1. Field of the Invention
The present invention relates generally to the recovery of water from an underground source through the use of a reciprocating pump system. The present invention relates more specifically to an improved water pumping system adapted to be driven by a windmill that utilizes an air lift fluid pump for generating a flow of water to the surface.
2. Description of the Related Art
Water pumping windmills may be found on farms and ranches worldwide and provide critical water supply for domestic and livestock use, especially in areas where electrical and fuel driven pumps are not practical. The type of technology associated with these windmill water pumps has enjoyed continuous use since the late 19th Century and may be generally illustrated by U.S. Pat. No. 1,632,188 assigned to the Dempster Mill Manufacturing Company (1927). This type of windmill pumps water by means of a positive displacement, reciprocating pump, submerged below the static water level of a drilled well. The pump is conventionally connected and supported by a water discharge pipe which leads to the surface and a reservoir for the water. The pump is driven by a reciprocating rod, typically made of wood or fiberglass, which reaches down from the windmill's transmission to the pump through the discharge pipe.
It is typical in reciprocating water pumps of this type to utilize a barrel or cylinder within which a piston is moved in a reciprocating motion by the pump rod. Both the piston and the bottom of the pump barrel incorporate check valves that allow water to flow only in the upper direction. The check valve at the bottom of the cylinder is commonly called the foot valve, while the valve in the piston is commonly called the lift valve. When the piston is lifted by the pump rod attached to the surface windmill, the lift valve closes and the piston lifts the entire column of water above it until water overflows out of the discharge pipe at the surface. At the same time a slight suction is formed under the piston causing the foot valve to open and water to flow in under the piston. During the next half of the cycle the piston moves down causing the foot valve to close and the lift valve to open such that water flows through the piston into a position to be lifted during the next half cycle.
Water flow valves, such as those described above, must be periodically replaced. The lift valve, which is typically made of leather or rubber, eventually wears due to particles of sand or earth in the water. Other check valves involved with the system also have finite useful lives and must be replaced on a regular basis. Replacement typically involves the removal of the pump rod, discharge pipe and pump by lifting the entire assembly up from the drilled well in order to access the valves. Such replacement efforts involve considerable labor and expense and greatly affect the down time of the windmill pumping system.
Obviously many efforts have been made in the past to replace the windmill pumping system powered by electrical motors and internal combustion engines. The present concern relates only to such efforts that have sought to improve upon wind driven pumping systems. One effort in the past is described in U.S. Pat. No. 3,367,281 issued to Gray on Feb. 6, 1968 entitled APPARATUS FOR PUMPING WATER FROM WELLS USING WIND POWER. The Gray patent discloses a water pumping device in which compressed air is generated by a windmill, stored in a tank, controlled through a pressure regulator, and delivered to a displacement type water pump. This invention, although not overly complex, is not directly adaptable to the typical windmill structure. The Gray disclosure describes a down stroke of a windmill pump rod as the compression stroke which does not lend itself well to application in conjunction with typical windmills that are designed to apply force and power on the upstroke of the pump rod. The pump rod conventionally made of wood would likely snap if used to compress air on the down stroke. The Gray invention also utilizes solenoid valves that are electrically controlled to effectuate the air compression cycle. Such electrically controlled valves are typically not practical in remote windmill locations. Finally, the Gray invention further requires the use of an air hold-up means and a pressure regulator.
U.S. Pat. Nos. 4,385,871 and 4,358,250 provide further examples of inventions generally related to the conversion of wind energy into compressed air for the purpose of water pumping. These earlier efforts, however, also do not address an appropriate adaptation of the air compressing mechanism to the typical windmill structure or to the utilization of the same in conjunction with an air injection type water pump.
It is therefore an object of the present invention to provide a water pumping system that is driven by a reciprocating windmill pump rod that is inexpensive to produce, install, maintain and operate.
It is a further object of the present invention to provide a water pumping system that may be retrofit onto existing reciprocating windmill structures and thereby replace the reciprocating water pump system utilized thereon.
It is yet another object of the present invention to provide an air lift water pumping system that retrofits to existing windmill structures and eliminates the heretofore required maintenance efforts associated with windmill well pumps.
It is a further object of the present invention to provide an improved air lift water well pumping system that may be retrofit onto existing windmill structures and which utilizes the upstroke as the power stroke in providing compressed air to an airlift pump positioned below the water level under the ground.
In fulfillment of these and other objectives, the present invention provides a system for pumping water from a well drilled into an underground water source that is operable in association with the windmill having a tower frame, a wind driven turbine, and a reciprocating pump shaft operably connected to the turbine. The system includes an air pump mechanically linked to the reciprocating pump shaft of the windmill and operable by the direct reciprocating motion of the shaft. The air pump is positioned within the windmill tower frame in line with the shaft and is held stationary with respect to the ground. The air pump operates through the reciprocating motion of the windmill shaft and delivers a flow of compressed air from an outlet port. An air conduit is connected to the outlet port and is directed into the well down to a point below the water level within the well. An air lift fluid pump is positioned within the well and comprises a fluid conduit with a first end positioned below the ground within the water table for receiving a flow of water there from, and a second end that extends above the ground for delivering a flow of water thereto. The air lift fluid pump comprises a submerged mixing chamber wherein compressed air received from the air conduit from the surface is injected into the mixing chamber forming a buoyant air-water mixture. This buoyant mixture flows towards the surface which in turn draws water up through the fluid conduit to the surface.
Other objectives will become apparent to those skilled in the art from a reading of the following description and consideration of the appended drawings.
FIG. 1 is a partial cross-sectional view of the entire assembly of the present invention shown installed on a typical windmill structure.
FIG. 2 is a detailed view of the air pump associated with the system of the present invention.
FIG. 3 is a detailed view of a first preferred embodiment of the air lift fluid pump associated with the system of the present invention.
FIG. 4 is a detailed view of a second preferred embodiment of the air lift fluid pump associated with the system of the present invention.
Reference is made first to FIG. 1 for a detailed description of the overall system of the present invention. The invention is intended to be utilized in conjunction with either an existing windmill system or to be installed in conjunction with a newly operable windmill system of the type typically employed in remote locations. The present invention is utilized in conjunction with windmill 10 that typically incorporates wind turbine 12 positioned at the apex of a tower frame 14 constructed on the ground. Windmill 10 incorporates a reciprocating shaft 16 that is attached to wind turbine 12 and moves in a direct reciprocating motion up and down with respect to the ground surface. Reciprocating shaft 16 typically terminates at an in-line linkage 18 that in the prior art is attachable to a down shaft that extends into the well 32. In the present invention, in-line linkage 18 is attached instead to air pump 20 as shown. Air pump 20 is positioned within tower frame 14 and is held in a relatively fixed configuration by pump supports 22 and 24. It is anticipated that lateral pump supports 22 will fix air pump 20 in a position immediately below reciprocating shaft 16 while vertical pump supports 24 will maintain air pump 20 in a fixed vertical position despite the reciprocating motion of reciprocating shaft 16. Air pump 20 delivers a flow of air by means of the motion of piston rod 26 (see FIG. 2) and piston plunger 28 within the air pump cylinder. This air flow moves from air pump 20 through air conduit 30 down into well 32 as described in more detail below.
Well 32 is typically constructed utilizing well casing 34 that extends into an underground water source 44. Fluid conduit 38 extends into well 32 to a point below the water level of underground water source 44. Air conduit 30 extends from air pump 20 above the surface to air lift fluid pump 36 below the surface. The operation of air lift fluid pump 36 is described in more detail below. In general, however, an air injection port 40 provides a flow of air into fluid conduit 38 which results in the lifting of water within fluid conduit 38 up to the surface. At the same time, water enters fluid conduit 38 at a first end 42 thereof positioned within underground water source 44.
Reference is now made to FIG. 2 for a detailed description of the structure and operation of air pump 20 positioned as indicated in FIG. 1. Air pump 20 is linked to the reciprocating motion of the windmill by means of reciprocating shaft 16 connected through in-line linkage 18 to piston rod 26. Piston rod 26 is attached as typical to piston plunger 28 which is free to move up and down within air pump cylinder 29. Any of a number of inexpensive air pumping systems configured as shown are available in the industry.
In order to take advantage of the upstroke/power stroke of the typical windmill system, air pump 20 of the present invention is fitted with a number of air conduit sections and check valves designed to direct a flow of compressed air down air conduit 30 into the water well. Air pump 20 incorporates upper air outlet port 50 and lower air outlet port 52. During an up stroke, air is drawn through air filter 60 and through check valve 58 into the lower chamber of air pump cylinder 29. During the upstroke, air in the upper chamber of air pump cylinder 29 is compressed until it exceeds the air pressure within the air conduit 30 extending into the well. Once this pressure is exceeded, check valve 54 opens and compressed air is allowed to flow into the well as described in more detail below. In this manner, utilization of the power stroke of the typical reciprocating shaft windmill is utilized while the return stroke (the downward stroke) is used to simply refresh the air within air pump 20. During the down stroke air is expelled from the lower chamber of air pump cylinder 29 and is directed into the upper chamber thereof through check valve 56.
Positioned in association with air filter 60 is pneumatic oiler 59. This device, well known in the art, facilitates the operation of the air pump by allowing a small amount of lubricant to flow into the pump with the air. Under conditions where potable water is required the lubricating oil should be a food grade oil or the equivalent.
Reference is now made to FIG. 3 for a detailed description of the structure and function of a first embodiment of air lift fluid pump 36. Water well 32 is drilled through the ground into the area of an underground water source 44. Typically, well 32 incorporates well casing 34 to prevent breakdown of the walls in the well. Positioned below the water level of underground water source 44 is a first inlet end 42 of fluid conduit 38. Positioned apart and vertically higher than first end 42 of fluid conduit 38 is air lift fluid pump 36. In the generic preferred embodiment air lift fluid pump 36 comprises an air injection port 40 (as in FIG. 1) that delivers compressed air received by way of air conduit 30 into fluid conduit 38. In the first preferred embodiment shown in FIG. 3, air lift fluid pump 36 comprises a concentric, cylindrical bell enclosure 37 that surrounds a section of fluid conduit 38 as shown. The section of fluid conduit 38 within the confines of cylindrical enclosure 37 is perforated by a plurality of holes 41 that constitute the air injection port 40. In this manner, air pumped through air conduit 30 into air lift fluid pump 36 is directed by pressures within cylindrical enclosure 37 through holes 41 of air injection port 40 into fluid conduit 38 and therein mixes with the water contained in fluid conduit 38. The water-air mixture within fluid conduit 38 is buoyant, and therefore rises to the surface under the force of the hydrostatic pressure of the surrounding water entering through the first end 42 of fluid conduit 38. In this manner, a flow of water is created from the first end 42 through fluid conduit 38 to the surface where it may be stored in a reservoir or utilized as needed.
FIG. 4 shows an alternate preferred embodiment for air lift fluid pump 36. In this embodiment first open end 42 of fluid conduit 38 comprises the open end of cylindrical bell enclosure 37 as shown. Air conduit 30 in this embodiment extends into cylindrical enclosure 37 and is perforated by a plurality of holes 43 that constitute the air injection port 40 (of FIG. 1). In this embodiment the air mixes with the water within enclosure 37 and flows upward into fluid conduit 38 in the same manner as described above with respect to the first embodiment of air lift fluid pump 36.
The combination of the air pump and air lift fluid injection pump of the present invention works with greatest efficiency when it is submerged to a point where approximately 60% of the total length of fluid conduit 38 is submerged underwater. A certain water pressure exists at the preferred depth of the air injection pump and it is this pressure that the compressed air must overcome in order to create bubbles in the mixing chamber. The air pump arranged as described above to compress air and deliver it into the well is sized such that the pulling force available from the power stroke of the pump rod of the typical windmill is enough to overcome the force on the air cylinder at the air pressure required for an air injection pump at the depths encountered. The present invention has been shown to be operable in a well where the water is approximately 100 feet below the surface. The air injection pump, under such conditions, is submerged at 150 feet below the water level where the water pressure is approximately 65 pounds per square inch. It has been determined that an existing windmill structure with a 12-foot diameter turbine is capable of approximately 765 pounds of pulling force. A four inch bore cylinder for the air pump as described may therefore be driven by such a windmill when the cylinder is under 65 psi of pressure. The water pumping apparatus constructed in this manner is capable of producing between two to three gallons per minute of water under 15 mph wind speed conditions.
Although the present invention has been described in conjunction with a specific preferred embodiment, it is anticipated that those skilled in the art will identify further embodiments and modifications that fall within the spirit and scope of the invention. Other types of air compression/air pump mechanisms may be utilized in place of the described air pump as an example. Similarly, alternative air lift fluid pumps may be utilized in conjunction with the system of the present invention without departing from its scope. The range and scope of the present invention is more completely described in the appended claims.

1. Field of the Invention
The present invention relates to a machine for manufacturing folded boxes with sheet material, and is particularly concerned with the drive of a machine which processes corrugated cardboard boxes, i.e. printing, creasing, cutting and folding such boxes.
2. Description of the Prior Art
The machines heretofore known generally process sheets, by printing and cutting the sheets, to manufacture folded and assembled, i.e. glued, boxes.
The first operation to be performed is the printing. Then comes the creasing of the longitudinal folding lines. It should be noted that sheets have already have transverse folding lines thereon. The third operation is the slotting of the front and rear edges of the sheet, in alignment with the folding lines, so that areas, which are to be folded and glued in order to form a box, are created around the sheet. In a fourth operation, holes to ensure ventilation or easy handling of the boxes are cut out of the sheet.
Normally these operations are performed by devices with tools working like mills.
Each printing unit includes a lower printing cylinder operating jointly with an upper pressure cylinder. The creasing elements are constituted by upper and lower tools mounted on four transverse shafts arranged in successive superposed pairs. A slotter unit, also having two pairs of superposed shafts on which the slotting tools are mounted, follows the creasing elements. The slotting tools comprise upper knives mounted around a cylinder and cylindrical lower counterparts facing the upper knives. The slotter can also be provided as well with tools for cutting the lateral edges of the sheets, as with tools for cutting the gluing flaps. The slotter could be provided with two transport bores arranged one above the other and located between the two pairs of superposed shafts to improve sheet transport.
The slotter is followed by a cutting station for special cuts on the blank, such as ventilation holes or handles. This cutting station comprises an upper tool-bearing cylinder acting on a lower angle cylinder made of steel. In certain cases, the anvil cylinder can be made of steel with an elastomer covering. For good transport of the sheets in this unit, conveying elments are mounted on each side of the lower and upper cylinders, as in the slotter.
The upper and lower shafts of the various units are driven by gears ensuring equivalent circumferential speeds for all elements which touch the sheets. There is a device for the angular setting of the slotting and cutting tools, with regard to the position of introduction of the sheets at the entrance of the units. Therefore, the tool-bearing cylinders are set in registration with the sheets to be processed.
The various printing, creasing, slotting and cutting tools are laterally shiftable along their respective shafts, so that they can process boxes of different widths and shapes. These shiftings are performed by moto-reductors driven by a central unit, into which, for example, various values can be registered, according to the size of the boxes to be manufactured. This central unit provides the required orders to the various moto-reductors.
The precreasing, creasing, slotting and cutting units are included in a machine ensuring the feeding, printing, folding and stacking of the different sheets. This type of machine, therefore, enables the manufacturing of a given amount of finished boxes depending on the length of the introduced boxes, and from the circumference of the slotting and cutting tools, for a given speed of the sheet transport. Moreover, as the mechanical driving of the various elements of the machine involves running inaccuracies, the register setting of the various elements is very difficult.
Because of these registration errors, a sheet cannot be processed with great accuracy, and the adjusting of one element with respect to another requires an expensive and complicated structure.
The object of the present invention is to provide a machine which does not suffer from the above-mentioned registration drawbacks and which noticeably improves the accuracy of the manufactured blanks.
The above object is achieved in a machine for manufacturing folded boxes with sheet material which comprises successive stations working in synchronism, the stations including a feed station, a printing station, a cutting station, a folding and gluing station and a piling-up and delivery station. The machine is characterized in that the feed station is provided with means to feed the machine with a pile of sheet material, means to center a pile of sheet material, means to square an upper sheet pack of the pile, and means to individually feed the uppermost sheet of the pile. The machine is further characterized in that a centering station is provided with means to center a sheet and means to sequentially feed a sheet into the printing station. The machine is further characterized in that the printing station comprises several printing units operable with printing cylinders located on the bottom of the printing units. The machine is further characterized in that the cutting station comprises two successive cutting units. One of the cutting units is mounted on means to enable its setting for in or out of operation. The folding-gluing station comrises a telescopic conveyor ensuring the transport of the sheets when the cutting unit is out of operation. The piling-up and delivery station is provided with counter-stacking means and pack conveying means. The elements of the stations are driven by D.C. motors commanded by a D.C. control and a control for the registration, data processing and programming. The elements of the stations are laterally shifted with asynchronous motors controlled by an A.C. control.
Other objects, features and advantages of the invention, its organization, construction and operation will be best understood from the following detailed description, taken in conjunction with the accompanying drawing, on which:
FIG. 1 is a schematic illustration of a machine for manufacturing boxes;

The machine for manufacturing boxes illustrated in FIG. 1 comprises a feed station A, a positioning station B for the corrugated cardboard sheet delivered by the station A, a printing station C comprising four printing units 1, 2, 3 and 4, a cutting station D having a creasing unit 5, a slotting unit 6 and a cutting unit 7, a folding-gluing station E, and finally a stacking and delivering station F.
The feed unit is constructed with a pile feed device 8 working in conjunction with a feeder 9 comprising a pile elevator 10 and a pusher 11 which takes off the uppermost sheet from the pile 12, in order to push the same in continuous cycles into the machine. The pile 12 introduced into the feed unit is first centered with respect to the median axis of the machine by way of lateral stops, then its upper sheets are squared with front and side stops, and advanced to the positioning station B. The sheet positioning station B is provided with a register chain and push lugs 13 ensuring the sequential advance of the sheets, so that the sheets are driven in registry with the printing plates mounted on the printing cylinders of the printing station C. The push lugs 13 work in conjunction with lateral guides (not shown) ensuring the proper positioning of the sheet, with respect to the median reference line 32 (FIG. 1b). An ejection device eliminates the damaged or inadequate sheets. The same is located in the positioning station B.
FIG. 1 illustrates that if some printing units are not needed they are set out of order. Here, the printing stations 2 and 4 are not working and have been lowered to the non-operating position.
In order to warrant the accurate transport of the sheets, a pressure roller 15 takes the place of the previously occupied printing cylinder. The roller 15 is mounted on a longitudinally-shiftable lever arm. Therefore, set out of order, the printing unit can be prepared for a new job without stopping production.
The creasing unit 5 of the cutting station D comprises two successive creasing elements. Each element is constructed of a lower cylinder 17 and an upper cylinder 18. The upper cylinder 18 is provided with creasing tools and the lower cylinder 17 is provided with the usual counterparts. The slotter 6 comprises two successive slotting units constructed of a tool-bearing upper cylinder 19 facing a lower, grooved cylinder 20.
The slotting unit 6 is followed by a cutting unit 7 having an upper tool-bearing cylinder 21 facing a lower anvil cylinder 22. The cutting unit 7 is mounted in such a manner that it is lowered when set out of order, as illustrated in broken lines in FIG. 1. If the work is to go on without using the cutting unit 7, the spare space it frees behind the slotting unit 6 will be occupied by a telescopic conveyor 23. As soon as the telescopic conveyor 23 is properly positioned, the adjusting, setting and positioning of the new tools on the upper tool-bearing cylinder 19 of the cutting unit 7 can be achieved while the machine is in production. The cutting station D also comprises a waste evacuator 24 located beneath the sliding and cutting units 6 and 7.
The folding-gluing unit E comprises, in addition to the telescopic conveyor 23, several lower belt conveyors 26 and upper belt conveyors 27 extending side-by-side. These upper and lower belt conveyors 26, 27 ensure the transport and the folding of the blanks produced by the cutting station D. The telescopic conveyor 23 fills the spare space between the cutting unit and the folding-gluing station E, when the cutting uhit 7 is lowered and set out of order (as illustrated in broken lines in FIG. 1). A blank gluing device (not shown) is arranged at the starting area of the upper and lower endless belt conveyors 26 and 27. The stacking and delivery station F follows the folding-gluing station E. It is provided with a counting-piling-up device 28 which delivers packs 29 with a given number of folded blanks to a pack conveyor 30 which transfers the packs 29 to a bundling machine (not shown).
FIG. 1a illustrates the sequential operation of the machine. Only the main guide motors are illustrated. FIG. 1b schematically illustrates the operational chain for the lateral shifting of the machine elements, as well as the various positions of a sheet being processed in the successive stations of the machine. The motors demanding the pile feeding device 8 and the pile elevator 10 are not illustrated on the drawing. The command motor of the pusher 11 in the feeder 9 is a motor M9. The command motor of the positioning station B is a motor M1, which also commands the lower and upper cylinders 17, 18 of each creasing unit. The motor M1 also drives the lower and upper conveyors 31 of each printing unit 1, 2, 3 and 4. The printing units are commanded separately, i.e. a motor M2 drives the printing unit 1, a motor M3 drives the printing unit 2 a motor M4 drives the printing unit 3 and a motor M5 drives the printing unit 4. The slotting unit 6 is driven by a pair of motors M6 and M7. The motor M6 drives the upper tool-bearing cylinder 19 and the lower, grooved cylinder 20 of the first slotter, while the motor M7 drives the upper tool-bearing cylinder 19 and the lower, grooved cylinder 20 of the second creasing unit of the slotting unit 6. The upper tool-bearing cylinder 21 and the anvil cylinder 22 of the cutting unit 7 are driven by a motor M8. The folding-gluing station E and the stacking and delivery station F are driven by a motor M10.
FIG. 1b illustrates the operations required for lateral setting of the various stations according to sheet width. The lateral setting is based on a median line 32. FIG. 1b also illustrates the motors to be used for the length registration in the printing, slotting and cutting operations. The sheet 34 is illustrated along its run in the machine. Its various locations are more specifically referenced 34a-34i. In the feed station A, the upper sheets of the pile 12, indicated at 34, are squared against lateral guides, one of which is actuated and the other of which is fixed. The location of these guides or stops is to be set according to the width of the sheet to be processed. To this end, two motors, i.e. a motor M21 for the fixed stop and a motor M22 for the actuated stop are employed. The setting with respect to the sheet length is performed by a motor M20 which shifts the feeder 9 forward or backward on its frames having a rear stop. The feeder 9 and the stops are therefore set simultaneously. In the positioning station, the sheets indicated at 34b are accelerated, then precisely aligned on their rear edges, in order to register with respect to one another, by way of chain register and push lugs 13 (FIG. 1). Simultaneously, the sheets are again aligned laterally, so that they are finally perfectly positioned with respect to the median line 32. The chain and push lugs register 13 comprises two conveyors having grooved belts 35 (FIG. 1) provided with fingers 36 mounted on two laterally-shiftable supports driven by a motor M23 for the left conveyor with respect to the direction of the arrow 37 and a motor M24 for the right conveyor with respect to the same direction. The lateral alignment of the sheet is achieved by a fixed guide on the frame of the right conveyor and by a guide mounted with springs on the left conveyor. Therefore, by laterally setting the right and left conveyors, one also achieves the setting of the sheet alignment elements. In the positions 34c and 34d, the sheet 34 is lying in the printing station C. The sheets are shifted separately from one printing unit into the other by lower and upper conveyors 31 (FIG. 1) arranged against a common slide moving transversely along cylindrical bars. The left lower and upper conveyors 31 are laterally set by a motor M35, whereas the right upper and lower conveyors are laterally set by a motor M39. If the printing is to be extended on the entire lower face of the sheet, the sheet cannot be carried by the lower conveyors. In such a case, the sheet is to be pressed against the upper conveyors by a device which creates a vacuum. Eah printing unit 1-4 is provided with such a device. The engraved cylinder of each printing unit 1-4 can also shift laterally in order to register the prints of the various printing units. For this purpose, the cylinder is mounted on bearings, which bearings are laterally shifted by a plurality of motors M105, M106, M107 and M108, respectively connected with the printing units 1, 2, 3 and 4. The registration of the printing units 1-4 is controlled by an electrical circuit which modifies the angular position of each motor M2-M5 (FIG. 1a) driving such units.
In the cutting station D, the lower and upper cylinder 17, 18 of each creasing unit are provided with lower and upper creasing tools, as well as with flap-forming tools. There are five lower and upper creasing tools and flap-forming tools, mounted side-by-side on the entire width of the machine on a first creasing shaft, called the pre-creasing shaft, and four tools on the second creasing shaft. They must, of course, be laterally adjustable, so that they can process various sheet sizes for various kinds and sizes of box blanks.
Therefore, the lower and upper creasing and pre-creasing tools arranged along the median line 32 are definitely set, whereas the upper and lower creasing and pre-creasing tools, located on both sides of the line 32 are laterally shiftable with respect to the location of the creasing to be achieved. The lower and upper pre-creasing tools, as well as the tool positioned exactly on the median line 32 and the flap-former, are arranged with two pre-creasing tools on the left and one flap-former on the right. A motor M31 achieves the positioning of the right pre-creasing tool, and a motor M32 sets the right flap-former. The first left pre-creasing tool is set by a motor M30, whereas the setting of the second right pre-creasing tool and the flap-former connected therewith is achieved by a motor M29. Four creasing tools are to be mounted on the creasing shaft and are aligned with the pre-creasing tools. These tools are shifted laterally by the motors also used for the setting of the pre-creasing tools, i.e. the motors M29, M30 and M31.
The cutting station D also comprises two slotting units, each comprising an upper tool-bearing cylinder 19 and a lower-grooved cylinder 20 (FIG. 1). The first slotting unit is provided with three sets of slotting tools and another set, constructed of a slotting tool and two flap-cutting tools. The second slotting unit is provided with a set including a slotting tool, with two flap-cutting tools and three sets of slotting tools having a circular knife. The lateral arrangement of these various tools on the respective shafts is identical to the tool arrangement of the creasing units. Therefore, the same motors 29-32 ensure the lateral shiftings of all pre-creasing, creasing and first and second cutting tools. The slotting tools are also angularly shiftable on the circumference of their respective tool-bearing cylinders, by way of a motor M33 for the tools of the first slotting unit and by way of the motor M34 for the tools of the second slotting unit. This angular shifting permits the accurate location of the slots.
Refering again to FIG. 1b, the position of the sheet is indicated by the reference 34f. In FIG. 1, in its working position the cutting unit 7 following the two slotting units is actuated separately by the motor M8 (FIG. 2), which is set and registered with respect to the speed of the other members of the machine. When the cutting unit 7 is out of order, the motor M8 becomes independent and is driven by an auxiliary command. The cutting unit 7 constructed of the upper tool-bearing cylinder 21 and the lower anvil cylinder 22 is located between the two pairs of driving shafts 39 (FIG. 2). The upper tool-bearing cylinder 21 comprises a transverse groove into which a tool bearer with a transverse knife is mounted. It is also provided with a range of tapered holes for mounting the cutting tools. The lower anvil cylinder 22 is mounted on two bearings vertically shiftable by way of hydraulic jacks, so that it can be lowered, in case of a jam for example. This vertical shifting of the lower anvil cylinder 22 also permits the accurate setting of the spare space between its surface and the transverse knife. Moreover a mechanical device permits the shifting of the transverse knife in such a way that it faces exactly a longitudinal groove on the lower anvil cylinder 22, when the knife is not used. Therefore, the transverse knife does not work with the lower anvil cylinder. The useless wearing of the knife is therefore avoided. Jacks lifting or lowering the entire element set the frames bearing the lower anvil cylinder. Depending on particular sheet size conditions, the transverse knife can cut the sheet into two halves, thus doubling the output of folded boxes. Electrical securities prevent erroneous manipulation of all these elements. The reference 34g illustrates the position of the sheet in the cutting unit 7. The slots have already been cut and the sheet is parted into two blanks 40 and 41 by the transverse knife.
The blanks 40 and 41 illustrated at 34g are inserted into a folder-gluer 42 (FIGS. 1 and 1a) by a conveyor 23. The conveyor 23, combined with the folder-gluer 42, constitutes the folding-gluing station E. The upper and lower belt conveyors 26 and 27 and the conveyor 23 are supported by two bars facing one another, one on the right and one on the left of the direction of sheet travel illustrated by the arrow 37. These two bars are to be set laterally according to the foldings requested on the blanks 40 and 41, shown as they are folded at 34i. The flaps of the box blanks 40 and 41 are folded one above the other by the upper belt conveyors 26.
The linear speed of one of the upper and lower conveyors 26, 27 is adjusted to the folding conditions by way of a speed control which lowers or increases the speed at request. The folding-gluing station E is driven by a motor M10, the speed of which is adjusted to the cutting conditions, i.e. if the machine is processing two half sheets, for example. In such a case, the working speed is to be increased by approximately 15% of the normal working speed, and the blanks 40 and 41 are then separated at the output of the cutting unit 7. The folding-gluing station is provided with a gluing device 43 (FIG. 1a) at the beginning of the folder-gluer 42. The right and left bars are to be positioned with accuracy by shifting the right bar with a motor M37 and the left bar with a motor M36. The lateral positioning of the gluing device 43 is performed by a motor M38 (FIG. 1b). All the shiftings are controlled by the central control unit of the machine. Limit switches prevent any erroneous manipulation of the machine. At the output of the gluing station E, the folded blanks 40 and 41 are counted and stacked in packs in the stacking and delivery station F. The piles are then transferred to a bundling machine and stopped or dispatched. The motors M1-M10 are all D.C. motors, whereas the motors M20-M24 and M29-M38 are A.C. motors. The machine is provided with a register control device, which warrants an accurate positioning of each sheet at the entrance of the stations A-F.
FIG. 2 illustrates the drive control, and particularly the control of the motors M1-M10. The motors M20-M24 and M29-M38 are commanded by a microprocessor, which processes the data regarding the sheet width and lateral positioning of the creasing and slotting. As illustrated in FIG. 3, the driving control of the motors M1-M9 includes a control unit I comprising a code-generating circuit 50, a synchronization circuit 51 for each motor M1-M9, a curve-generating circuit 52 for the motor M9, a calculating unit II comprising a microprocessor 53, input and output circuits 54, an input circuit with interruption control 55, a signal conditioning unit III including a sensed discrimination element 56 multiplying by four pulses generated by the pulse generators Gl-G9 of FIG. 2 for the motors M1-M9, as well as a conditioner 57 for the interphasing and the conditioning of all signals between the machine and the units I and II, and a logic command unit IV of the machine including a driving selection circuit 58 and a logic manual command selection circuit 60. The motor M10 is controlled directly without a synchronization circuit code C10 produced by the code generator 50, with respect to the single or double cutting mode.
The operation of the various elements is described with reference to FIG. 2.
The code generator 50 produces an analog speed code CA, a digital rotation code CD, a digital shifting code DD with respect to the manual or automatic operating mode, an analog acceleration code ACC and a signal V≧VL for the manual command circuit 60. The code generator 50 includes a counter/decoder which memorizes the operating speed of the machine. This operating speed can be increased or reduced at request. The code generator 50 also includes an analog/digital converter for converting the digital speed reference into an analog speed reference. The code generator 50 is also provided with a curve generator so that an analog speed code CA is produced without any acceleration jerk. The analog acceleration code ACC is also delivered by the curve generator. The code C10 for the motor M10 is derived from, for example, the single or double size mode of the machine. The information on the single/double cutting mode S/D is generated by the calculating unit II. The code generator 50 also comprises a tension/frequency converter driven by the analog speed code CA to produce the digital rotation code CD, as well as a frequency generator driven by an automatic/manual control line to generate the digital shifting code DD. The code generator is also provided with a comparator for producing the information V≧VL for the logic manual command circuit 60. In short, the information fed into the code generator 50 is:
(a) One S/DM signal establishing manually a single or double operating mode;
(b) A signal S/D generated by the calculation unit II preestablishing automatically the single or double size operating mode;
(c) A signal A/M for the manual or automatic mode selection;
(d) Signals AI for instant stop;
(e) Acceleration signals ACC;
(f) A deceleration signal DEC;
(g) Slow working signals ML; and
(h) Starting signals DEM.
The code generator 50 produces a plurality of signals CA, CD, DD and ACC, the signal V VL already mentioned above, and the signal MA, i.e. machine stopped signal for the analog circuit of the driving selection circuit 58.
The synchronization circuits 51 constitute the second element of the control unit I. Each circuit 51 includes an adder which delivers a current code Icons. The current code Icons is calculated by the adder on the basis of a dual code delivered by a speed regulator combined with an analog acceleration code ACC produced by the code generator 50. Each synchronization circuit 51 has a speed adjusting loop, with a feedback from a speed measurement device based on the pulses of the pulse generator G1-G8 of each motor M1-M8. The speed code can result from the combining of the analog speed code CA, the speed correction signal CORR calculated by a position regulator, and a positive or negative internal speed reference. Each synchronization circuit 51 is also provided with a position-regulating loop ensuring the angular synchronization. This loop comprises a counter/decoder, a digital/analog converter and a position decoder, an analog/digital converter and a position regulator. The synchronization circuit is also provided with a command logic for the calculation of the required operations on the basis of the received orders.
The third element of the command unit I is a curve generator 52 comprising a binary counter/decoder, a memory, a multiplier, a divider and a command logic circuit. The binary counter/decoder is incremented by the positive pulses of the pulse generator G1 and deincremented by the negative pulses of the pulse generator G1 of the motor M1. These pulses have previously been treated by the conditioning unit III for the signals.
The memory maintains the curve shape characteristics to be followed by the movement of the motor M9. The multiplier calculates the speed code for the motor M9 and the divider adapts the incremental value of the pulse generator G9 of the motor M9 to the advance increment of the digital code CD' generated by the memory. The command logic controls the generator 52, while the shaft connecting the motor M1 to the generator G9 is coupled. Therefore, the respective signals entering the curved generator 52 are:
(a) The digital shifting signal DD delivered by the code generator 50;
(b) The analog speed of the motor M1 (VAM1) coming from the synchronization circuit 51 of the motor M1;
(c) The correct index setting indication of the motor M1 (index M1) of the synchronization circuit 51 of the motor M1;
(d) The positive or negative pulses GI1 provided from the pulse generator G1;
(e) The corect index setting of the motor M9 (index M9); and
(f) The positive or negative pulses generated by the pulse generator G9.
The signals produced by the curve generator 52 are:
(a) The processed positive or negative pulses GI' of the pulse generator G9;
(b) The processed digital shift signals DD';
(c) A digital code C'; and
(d) An analog code CA'.
All of the signals generated by the curve generator 52 are transmitted to the synchronization circuit 51 of the motor M9.
The calculating unit II comprises a microprocessor 53 which commands the following functions:
(a) Control of the equivalence of the programmed values and the actual state of the elements of the machine;
(b) Prepositioning the motors M1-M9 when the job is changed or after the interruption of the shaft connecting the motors;
(c) Angular correction of the motors M1-M9 by either actuation of a push button or by sheet register control units; and
(d) Control of the correct operation of the motors M1-M9.
The control mentioned under (a) above concerning the equivalence of the programmed values and the actual state of the elements of the machine must take place each time the job is changed. Therefore, the operator provides production data, i.e. the size of the box to be manufactured, the lateral positioning of the various tools, the list of the operating printing units and the information concerning the working or not working of the cutting unit by way of a console. This information belongs to the data base to be transmitted to the microprocessor 53 of the calculating unit II, as soon as the pre-positioning orders of the D.C. motors M1-M9 or the A.C. motors M20-M24 and M29-M39 have been given. On the other hand, the microprocessor 53 receives information from the input lines of the logic selection driving circuit 58 of the motors M1-M9. A pre-positioning order is provided by the console or by the index setting signal generated by the logic starting circuit 59. The microprocessor 53 then compares the list of the motors with the list of the effectively-selected motors, and announces any registered difference to the command console so that a message can be displayed on a screen.
The operation under (b) above concerning pre-positioning occurs when the machine working conditions are modified, i.e. if a new blank of different size is to be manufactured. To this end, the data base memorizing the information about a given job contains a value for every D.C. motor M1-M9, calculated by the command console on the basis of the geometrical dimensions of the box to be processed. During production, this value represents the actual angular phases of the motors M1-M9. This effective phasing is defined as the initial angular phasing increased by the sum of the angular correction registered from the start of the job. This operation can be reqested by the command console by way of a menu switch, or with a signal provided from the general index setting signal. The pre-positioning comprises detecting the "index OK" signal of the synchronization surface 51 of the motors M1-M9, then performing an angular correction of the phasing of the motors M1-M9 corresponding to the value previously memorized in the data base which stores the data of a given job. A pre-positioning routine checks if the selected motors corresponds to the programmed units, and if the list of the "index OK" signals corresponds to the list of the selected units. There is a deadline for performing this routine.
The function (c) of angular correction mentioned above with respect to the motors M1-M9 occurs while the machine is operating. To this end, five lines AD0-AD4 permit the recognition of the synchronization circuits 51 of the motors M1-M9 where the correction is to be made and determine the direction of correction, and a line CORR which receives a pulse, the length of which is proportional to the magnitude of the correction from the microprocessor 53 of the calculation unit II. During this pulse, the digital shifting signal DD produced by the code generator 50 is transmitted to the given synchronization circuit 51.
The maximum value the correction represents a complete revolution of a motor M1-M9. This allows the positioning of a motor to any angular value with a single correction routine. After the transmission of the correction, the routine resets the data base of the microprocessor 53. The correction routine is called by an order generator by the command console (index setting), or at the request of one of the register control units 66 and 67 (FIG. 4) for the register error correction. The correction routine can also be called by one of the command console push buttons 68 (FIG. 4) for manual correction.
The function (d) mentioned above concerning the control of the correct operation of the motors provides that the microprocessor 53 of the calculating unit II is provided with an "overflow" signal. If this signal is actuated, the microprocessor 53 immediately checks the input values "index OK" of all of the selected synchronization circuits 51 in order to determine which circuit, or circuits, have failed, and to display the information at a terminal. The calculating unit II receives the following data:
(a) The selection codes of the motors M2, M3, M4, M5, M8 with references S2, S3, S4, S5, S8 which are generated at the input of the logic drive selection circuit 58;
(b) The "machine stopped" signal MA produced by the code generator 50;
(c) The push-buttons "out of order" signals BPM3-BPM6;
(d) The digital shift code DD produced at the output of the code generator;
(e) The "index setting" signal MI and the "empty sheets" signal VF, both generated by the synchronization circuits 51 of the motors M1-M9;
(f) The "overflow" signal O generated by the synchronization circuits 51 of the motors M1-M9;
(g) The automatic/manual mode signal A/M generated by the command console;
(h) The "index OK" code generated by the synchronization circuits 51 of the motors M1-M9; and
(i) A signal P produced by the pulse generators GIAC of the motors M20-M24 and M29-M39 for the lateral positioning of the machine elements.
The data issued by the calculating unit II are:
(a) A reference for the single/double size S/D transmitted to the code generator 50;
(b) A microprocessor OK code, also sent to the code generator 50;
(c) A locking signal BL;
(d) An index memorization signal MEMI;
(e) An "index setting" order MI;
(f) A correction signal CORR; and
(g) Four addressing signals AD0-AD3 and a correction signal AD4, all being transmitted to the synchronization circuits 51 of the motors M1-M9.
The signal conditioning unit III receive data from the pulse generators G1-G9 of the motors M1-M9, which data are transformed into signals GI1 -GI9, and thus into the synchronization circuits 51 of each motor M1-M9.
The data entered into the logic driving selection circuits 58 are:
(a) The selection codes S2, S3, S4, S5 and S8 of the motors M2, M3, M4, M5 and M8;
(b) The "machine stopped" signal MA produced by the code generator 50; and
(c) A signal generated by a push button 65 which electrically uncouples the shaft and resets the motors M1-M9 to the initial conditions.
The values produced by the logic driving selection circuits 58 are:
(a) Selection orders SEL1, 6, 7, 9 for the synchronization circuits 51 of the motors M1, M6, M7 and M9; and
(b) The selection orders SEL2, 3, 4, 5, 8 addressed to the synchronization circuits of the motors M2, M3, M4, M5 and M8.
The logic command unit IV also includes the logic starting circuit 59 which performs the following operations:
(a) A start signal;
(b) Machine emptying if sheets are remaining;
(c) Slow running; and
(d) Normal running.
The start signal is a "hoop" actuated by any push-button for starting the machine. The emptying order, if sheets are remaining in the machine, works independently of the connection or disconnection of the electrical shaft of the motors M1-M9. This order then calls in the "slow running" signal from the code generator 50 and actuates the signal VF (emptying of the remaining sheets) for the synchronization circuits 51. A slow or normal running order can call in the function (b), index setting of the motors M1-M9, depending on the connection or disconnection of the electric shaft of the motors. The running mode can be changed from slow to normal or vice-versa, without stopping the machine.
The data entered into the log starting circuit 59;
(a) The signals STO provided from the "stop" push-buttons of the machine;
(b) The signals STA provided from the "start" push-buttons of the machine;
(c) The signal BL locking the electrical shaft of the motors M1-M9 if something goes wrong;
(d) The signal O indicating the interruption of the electrical shaft (synchronization out or lost);
(e) The emergency stop signal STU;
(f) The slow running signal ML;
(g) The machine emptying signal VF; and
(h) The general resetting signal RG restoring the initial conditions.
The data generated by the logic starting circuit 59 are:
(a) A start signal DEM, a slow running signal ML and an instant stop signal AI, all transmitted to the code generator 50;
(b) A signal AE OK indicating that the electrical shaft is all right; and
(c) The index setting signals MI and the machine emptying signals VF, both transmitted to the synchronization circuits 51 of the motors M1-M9 and to the calculating unit II.
The third element of the logic command unit IV is the logic manual command selection circuit 60 comprising push-buttons for the positive or negative command of each motor M1-M9. These commands have three different functions, which are:
(a) The analog forward/backward command for the synchronization circuits 51, which are not working in a correct electrical shaft mode;
(b) A forward/backward phasing digital command for the synchronization circuits 51 with the connected electrical shaft mode as the microprocessor of the calculating unit II is out of order; and
(c) The calling-in command of a correction routine for the microprocessor of the calculating unit II.
Except in case of emergency stop, the logic circuit of the manual command selection circuit must transmit the orders "positive or negative values of the push-buttons" for the selected motors. As far as the selected motors are concerned, the circuit 60 transmits the order "negative values of the push-buttons" only if the signals V≧VL or MEM index (FIG. 2) are generated so that no selected units can turn backward. The data sent to the logic manual command selection circuits 60 are:
(a) A signal V≧VL generated by the code generator 50;
(b) The emergency stop signal STU provided by the logic starting circuit 59;
(c) The signals S2, S3, S4, S5 and S8 selecting the motors M2, M3, M4, M5 and M8, provided by the logic drive selection circuit 58;
(d) The positive or negative data BM1-BM9 produced by the actuated push-buttons for the manual command; and
(e) An index memorization MI.
The data pduced by the logic manual command circuit 60 are primarily the signals BM1-BM9, positive or negative, which data are sent, on the one hand, to the synchronization circuits 51 of the motors M1-M9, and, on the other hand, to the microprocessor 53 of the calculating unit II.
FIG. 4 is a diagram of the drive of all motors of the machine, i.e. the connections existing between the various command elements of the D.C. motors M1-M9 and the A.C. motors M20-M24 and M29-M39. The calculating unit II receives specific data from the D.C. motors and A.C. motors. The D.C. motors M1-M9 are controlled by the circuits illustrated in the D.C. control circuit 77 of FIG. 4 enclosed in a broken line, whereas the A.C. motors M20-M24 and M29-M39 are controlled by the A.C. control circuit 78 enclosed within a continuous line. The controls 77 and 78 are commanded by a CTP central control circuit 79 which is enclosed in a dot and dash line. The elements of the control 77 described in FIG. 2 create an electrical shaft coupling between the motors M1-M9, establish the independent phasing of each motor M1-M9, achieve the index setting of all motors, i.e. position them on an identical reference, receive correction orders from the CPT central control circuit 79 while the motors M1-M9 are operating, and control the motor M9 with respect to one of the motors M1-M8. In the present case, the control of the motor M9 refers to the conditions of the motor M1, submitted to identical running conditions as for the motors M2-M8, when the electrical shaft coupling is established. The motor M9, controlled by the motor M1, warrants an independent rotation of the motor M9 during the rotation of the motor M1. The motor M9 drives the pusher 11 (FIG. 1) with a non-linear movement determined by the curved generator 52. The beginning and the end of the non-linear movement absolutely must be registered with the beginning and the end of a rotation cycle of the motor M1. Therefore, the curve generator 52 receives positive or negative pulses GI9 of the pulse generator G9 and digital shifting pulses DD produced by the code generator 50. The very high values of these pulses are processed to be acceptable for the synchronization circuits CS9 of the motor M9, and become the pulses GI9' and DD' at the output of the curve generator 52. The curve generator also receives from the synchronization circuit CS1 of the motor M1 positive or negative pulses GI1, the index setting signal M11 and analog speed signals VA1 of the motor M1. These values must be processed by elements of the curve generator 52 in order to deliver a positive or negative digital value CD' to be transmitted to the synchronization circuit CS9 of the motor M9. Therefore, the synchronization circuit CS9 of the motor M9 processes the values CA', CD', DD' and GI9' and generates a code current Icons 9 for the motor M9 which refers to the requested curve for the speed of the motor M9 during one cycle as to the curve of the constant speed of the motor M1 and ensuring, therefore, a perfectly-identical beginning and end of the cycle for both of the motors M1 and M9.
The operation of the D.C. control circuit 77 depends on the elements of the CTP central control circuit 79 for the register control, the processing and the programming. The CTP central control circuit 79 includes a register control unit 66 for the position of the transverse cutting only used with the double size operating mode, a color register unit 67 for the print positions in the printing means 1, 2, 3 and 4, a data processing unit 69 and a programming unit 70. The transverse cutting register unit 66 controls the registration of the cuttings and the prints on the sheet. It calculates the error between the sheet leading edge and a "cutting signal", given by a pulse generator mounted on one of the cylinders 19 or 20 of the first slotting unit. The leading edge detector is located between the printing unit 4 and the first slotting unit (FIG. 1). The information regarding the "cutting signal" is provided by the data processing unit 69. There are two methods for the calculation of an eventual register error correction. The first possibility is to calculate the register error on the basis of an average value measured on several sheet samples, therefore a correction should be done every x sheets. Another possiblity is to detect the position error for each sheet at the entrance of the first slotting unit, and to act immediately on the motors M6, M7, M8 of the slotting units and of the cutting unit 7, so that their angular positions are corrected with respect to the sheet infeed position. The calculation of the error correction on the first sheet is immediate, and the correction will operate simultaneously on the three motors M6, M7 and M8 driving the slotting units and the cutting unit 7. The forward or backward shifting, with respect to the sheet leading edge, can be done manually. During the automatic registration mode, the manual shifting commands of the motor M6 are locked, but the manual shifting commands of the motors M7 and M8 can modify the positions of the slots achieved in the second slotting unit, and of the cuttings performed by the cutting unit 7 with respect to the slots of the first slotting unit.
The color register control unit 67 measures and corrects the eventual register error of the prints achieved in the printing units 1-4. To this end, a pair of optical laser detectors read register marks always located on the same spot on the sheets. A reading aperture for these marks is generated by the detector of the sheet leading edge in the transverse cutting register unit 66. The correction orders are transmitted to the calcating unit II by way of the data processing unit 69, which transmits the signals with respect to the printing units being used.
The correction of the register error is calculated with an average value measured on several sampled sheets, taken off every x sheet. The calculating of the error and correction of the first sheet is immediate. In the automatic working mode of the color registration, the manual shifting commands of the motors M2-M5 are locked. However, the manual shifting commands of the printing units not being used are not locked, and with the help of three pairs of forward/backward push-buttons, the prints of the printing units 2-4 can be shifted with respect to the print of the printing unit 1, which is a reference unit. If an error appears between the print and the sheet leading edge, the motors M1-M9 can be commanded simultaneously and manually by push-buttons. The data processing unit 69 is the interface between the operator and the calculating unit II. This unit also comprises a cathode ray tube (CRT) screen. The data processing unit 69 can, on request:
(a) Call in a job programmed on the programming unit 70;
(b) Feed production data, i.e. box sizes, working speeds, jobs;
(c) Provide a pre-positioning order to the various motors to set the machine according to the data of the job to be achieved;
(d) Control the production;
(e) Calculate the real setting parameters; and
(f) Order the programming unit 70 to memorize the production data to be kept, once a job is finished.
The data processing unit 69 also ensures the interfacing between the register control unit 66 for the transverse cutting and the register control unit 67 for color registration and the calculating unit II. The correction order for the units 66 and 67 are directed by the data processing unit 69 to the printing units being used. The two units 66 and 67 will be connected to the data processing unit 69 by a connection element 80, also used to program the reading aperture of the transverse cutting register unit 66 with respect to the box to be manufactured. The data processing unit 69 will also receive from the calculating unit II regular information on the last position of the various D.C. motors and A.C. motors of the machine. These data are kept in protected memories belonging to the unit 69 so that a new start can easily be ordered if the synchronization of the motors M1-M9 is lost, in case of an emergency stop, for example. These data are provided from the machine and are able to generate a production diary, i.e. machine started, correct running of the sheets, production speed, etc, and are also transmitted to the unit 69 by this bus. The program unit 70 is connected to the data processing unit 69 by a connection 81. The program unit 70 can:
(a) Program new working data about the size and the shape of the boxes, the thickness of the material, and the list of colors used for printing;
(b) Check the jobs done in a potective memory, the data concerning the finished jobs, with all the corrections given during the job, and the production diary, etc.; and
(c) Control the stock list of the jobs kept and information concerning the spare space still available in the memory.
The various manual commands of the D.C. motors M1-M9 initiated by push-buttons are located on the same console, comprising the general console 76 and the command console 68 for the D.C. motors. The A.C. control circuit 78 illustrates the elements which manage the operation of the A.C. motors M20-M24 and M29-M39 for the lateral positioning of the various elements of the stations. Therefore, the A.C. control circuit 78 comprises an interface 71 for the connection of the pulse generator of the A.C. motors with the calculating unit II. The interface 71 transforms the data delivered by the pulse generators of the A.C. motors into a range of pulses and a signal giving the rotation sense of the motors. At each pulse, a processing routine provides a shifting direction and the beginning of the information. Therefore, the lateral position of each element of the various stations can be determined and controlled. The A.C. control circuit 78 also has terminal switches 72 for:
(a) Securing the operating security by locking the A.C. motor corresponding to the switch actuated when the switches 72 act on the A.C. control 74 of the A.C. motor; and
(b) Reset the element of the various stations into their original positions, when the positions of these elements is not known without absolute accuracy.
This can be done when the switches 72 act on the calculating unit II. All of the elements of the machine are then shifted until they are stopped by their respective switches; then, they are reset to the references memorized by the memory unit 70 at the start of the job. The A.C. control 74 of the A.C. motors receives orders from the calculating unit II and the A.C. command console 75. However, a shifting order can be locked either by the terminal switches 72 or an emergency stop of the machine. The A.C. control circuit 78 also comprises a control device 73 which is a shift detection device which establishes if the shifting of the elements of the stations ordered and controlled by the calculating unit II actually took place, when the calculating unit II was out of order. The control device 73 is a flip-flop circuit. When the calculating device II is started, it first detects the state of the flip-flop circuit. If this detection shows that a manual shifting occurred without control by the calculating unit, the resetting of the initial command conditions must take place before any new start. If, on the contrary, the detection shows that no shifting occurred, the calculating unit II immediately orders the start of the command device. Therefore, the operator has a driving device for the various motors of the machine for manufacturing boxes, allowing the free setting of the instant angular posions of all motors, this being done independently for each motor. Such a device can overcome the difficulty of obtaining a perfectly-accurate operation by the suppression of all mechanical perturbations of the drive systems heretofore known.
For a more detailed view of the structure set forth above, reference is now made to FIGS. 5-14 which illustrate operating elements of the machine.
Referring to FIGS. 5-8, the cutting unit 7 of the cutting station D is illustrated as comprising an upper tool-bearing cylinder 21 facing a lower anvil cylinder 22. The cylinders 21 and 22 are mounted between two lateral flanges 100 carrying the guide members 101 and 102. The guide members 101 and 102 comprise a recess 103 engaging a rod 104 when the cutting unit 7 is in its upper position. A roller 105 is fitted onto a guide member 101 and acts jointly with a guide rail 106 to allow guidance of the cutting unit 7 when raising. The guide member 102 is also equipped with a recess 107 which receives a rod 108 when the cutting unit 7 is in its upper position. The vertical motion of the cutting unit 7 is achieved by a pneumatic or hydraulic piston 109 carried on a frame 110 and equipped with a roller 111 which is entrained by a cable 112 with a roller 114, the cable 112 having one end fixed to a lug 113 and the other end attached to a connecting piece 115 carried on a plate 116 mounted at the upper end of the lateral flanges 100.
The lower anvil cylinder 22 may comprise a metal tube 117 including a recess 118 extending parallel to the longitudinal axis for receiving the cutting blade 119 of the upper tool-bearing cylinder 21 when no transverse cutting operation takes place. This is achieved by angularly displacing the position of the lower anvil cylinder 22 with respect to the upper tool-bearing cylinder 21. The tool-bearing cylinder 21 comprises a groove 120, as set forth above, which receives the tool bearer holding the cutting blade 119. The tool bearer may comprise fixing members 121 and 122 mounted in the groove by way of screws 123 and a screw 124 for pinching the cutting blade 119 between the fixing members 121 and 122.
FIG. 9 illustrates the telescopic conveyor 23 shown in the folding-gluing station E of FIGS. 1 and 1a. The conveyor 23 comprises two sets of belt conveyors 152 and 153 each of which is formed by a lower conveyor 154 and an upper conveyor 155. The lower conveyor 154 comprises a pair of flanges located on either side of the belt supporting arrangement of pulleys and rollers, the two flanges 156 being designed to slide along a beam 157 after release of a locking device 159 and movement of the hand grip 158. The upper conveyor 155 also comprises two flanges 160 supporting a similar arrangement of pulleys and rollers. The conveyor 155 is hung from a beam 161 and is slidable therealong by movement of the hand grip 162 upon release of the locking device 159. In order to ensure good transport of the cardboard sheets between the conveyors, a set of pressure rollers 163 is mounted under the flange members 160.
Referring to FIG. 10, the pile or stack centering structure of the feed station A is illustrated as comprising conveyor rollers 125 supporting a pile of cardboard sheets 126. At the beginning stage of operation, the lateral stop 127 is located in a position 127' and the pile 126 lies on a pile support 128 in its raised position. The support 128 is displaced in the direction of an arrow 129 in order to urge the lateral stop 127 down to operate a switch 130 to stop lateral movement of the support 128. The support 128 lowers and is then pulled back in its lower position to permit the pile 126 to engage the conveyor rollers 125 in a centered location.
In FIG. 11, the squaring device of the upper portion of the pile 126 is illustrated as comprising a movable stop 131 mounted at the end of a pneumatic or hydraulic piston 132 supported by a member 133 connected to a pair of guide rods 134. To set the position of the member 133 with respect to the size of the cardboard sheets a bearing 135 may be shifted along the guide rods 134, one of the guide rods being constructed as a screw engaging a nut in the bearing 135 (see the position 133'). The movable stop 131 acts jointly with an adjustable stop 136 mounted to another member 137 connected to a bearing 138. The assembly is supported by rods 139, again one of which is constructed as a screw engaging a suitable nut in the bearing 138 in order to adjust the lateral position of the stop 136 with respect to the size of the sheet, the maximum position being illustrated at 136'.
In FIG. 12, the dredge-type pushers 11 of FIG. 1 is illustrated as mounted on a tooth belt 141 by way of a screw 142 and a nut 143. Two pushers 11 are fixed onto the toothed belt 141 diametrically opposite one another. Immediately adjacent the tooth belt 141 is a sucker 144 for picking up the sheet 140 just before the picture 11 engages its trailing edge.
In FIG. 13, the general configuration of the dredge of the feeder 9 is illustrated. The toothed belt 141 is continuously driven by a pulley 145 (also shown in FIG. 12) in order to feed the sheet 140 in the direction of the arrow 146. The motion of the motor M9 (FIGS. 1a, 2 and 4) is transmitted to the shaft 147 of the pulley 145 by another toothed belt 148. The feeder 9 of the feed station A of FIGS. 1 and 2 is supported by a beam 149 extending transversely between the lateral frame 150 of the machine. A device comprising a hydraulic piston 151 is provided to raise the feeder when a jam occurs.
The lateral operating pushers and push lugs are illustrated in FIG. 14 for the positioning station B. A sheet 157, symbolically indicated by a dot-dash line, is fed from the feed station A and pushed forward from its rear edge by way of a finger 36 (also shown in FIG. 1) mounted on a grooved belt 35. The lateral alignment of the sheet is achieved by a guide 152. The position of the guide 152 is adjusted by a setting motor 153. The sheet 157 is maintained in a suitable position by the joint action of a lower plate 161 and an upper member comprising two upper guides 154 spaced apart from one another by a plurality of members 160. The upper members is hung by two sets of levers 159 attached to the upper guide 154 and to a pivot point 158. A set of rollers 155 provide guidance of the lateral edge of the sheet 157. A plurality of the fingers 36 are mounted on the belt 35 and the second conveyor of the positioning station B is designed on the same principle with the adjustable guide 152 being spring mounted.
The register control may advantageously be provided by a Bobst-Registron S2000 system available from Registron Bobst Champlain, Inc., Roseland, N.J.

Blog Mommas
A fun place to list your blog
July 23, 2016
With that said, I've decided to go ahead and remove the Blog Mommas Facebook and Blog Mommas Google+ pages. I'm also taking down the Blog Mommas Twitter List on my Twitter page. I think that's going to be a better fit for me personally. Less stressful, too.
I'd like to get back to writing more, networking with other writers, and hopefully I can be more hands on in responding to many of the posts I read throughout the year from your blogs. It's the interacting and networking with one another that floats my boat, and who doesn't love reading comments?
What have you been up to this summer? What do you think of my decision? I'd love to hear from you guys.

I'm excited to read this book!
Dr. Cloud's NEW book is called: The Power of the Other, The Startling Effect Other People Have on You, from the Boardroom to the Bedroom and Beyond – and What to Do About It by Dr. Henry Cloud.
I've always been a self-improvement fan. If there is solid advice out there from a reputable source, I'm usually the first to jump on it. I don't know about you, but I know that other people have a BIG effect on me, and I can't wait to see what Dr. Cloud has to say about it.
If you're interested in reading this book but don't want to buy it until you've had a test drive, you can find Dr. Henry Cloud on Facebook and read his first two chapters for FREE! He posted a link on April 29th giving his followers an opportunity to read the first two chapters. What are you waiting for? Have at it!
Stay tuned here though because I plan to blog about any quotes that I've read along the way, how they have impacted me, and what I plan to do with Dr. Cloud's advice. Or maybe stumbling on parts of the book will have me thinking about things differently? I'll be writing about those instances over the summer so please stay tuned for those upcoming blog posts.
If you decide to go ahead and pick up the book I hope you will chime in and let me know what you think of it. I'd love to dish about it with you, AND I LOVE to get blog comments, so please leave me a comment or two!!

Blog of the Month: Euchre Fun
Euchre Fun
One of these days I will investigate and find out just how fun it is to play Euchre. Are there any other Euchre players out there? What is it that you love about this game!? I'd LOVE to hear from you!

How to be selected for Blog of the Month
There are a couple of things you can do in order to be selected for Blog of the Month. Here are a few tips in no particular order:
- Make sure you are linking to Blog Mommas
The first thing I'll check is whether or not you're linking to Blog Mommas. Check your sidebar and make sure people can see your buttons and links. If folks have to scroll all the way to the bottom of the page or can't find any other pages where your links can be found, it makes things hard.
- Make sure your blog was added to the directory
Please let me know you're interested in being a part of Blog Mommas. In my sidebar on the right hand side there is a way for you to e-mail me and let me know. It's very easy to send me a quick message letting me know you want to be part of Blog Mommas and that you've linked to Blog Mommas. Some of you may have more than one blog and that's fine, I'd be happy to list all of your blogs. Once listed, I will introduce your blog to my readers and you'll automatically qualify to be selected as Blog of the Month.
- Invite your blog friends to join in on the fun
Tell your blog friends about Blog Mommas. There are perks to being a part of Blog Mommas and you will discover lots of new blogs to read. Some of my closest friends were made through just networking, reading other blogs, and leaving comments. Eventually we all get to know each other and a sense of community is developed, and new friendships made – for life!
Okay, I'm going to go check my e-mail and see if anyone has written me yet!
I can't wait to list your blog and start featuring blogs again!!

My Blog Comments Aren't Coming Through
Hello and Happy Spring!
I'm coming to you from my mobile device. It's pretty convenient doing it this way.
I've been reading your blogs, Blog Mommas. For some strange reason I don't think my comments are getting through and I'm not sure why?
I do all my blog reading from my feedly application. I've tried commenting through feedly. I've tried commenting through your main blog pages, and it doesn't seem to be working.
I can't see my comments.
I think I'm doing it wrong.
Maybe commenting from my laptop instead of commenting from my device would work better? I don't know.
I hope I can stick to my device because there are days I don't have time to log into my laptop.
How are you guys doing with leaving comments on blogs? Have you run into technical difficulties? Any idea what the problem might be?
