The specific embodiment
Produce simultaneously a large amount of single doughnut, for example 768 ultimate fibres according to the fibre spinning equipment of prior art.The described ultimate fibre of a spinning-drawing machine is merged into common bar and is supplied to up-coiler.Described up-coiler produces hollow fiber bundle by described, and described hollow fiber bundle is refitted in further operation.Here trimming refers to utilize and holds film described Shu Jinhang is held, will film is fixed and the bundle through holding is prescinded to required length around holding of holding of described bundle.Holding film is a kind of servicing unit in trimming is processed, and has following task, that is, make fibre bundle keep shape and make it possible to reliably the fibre bundle section being imported in filter box.After importing afterwards in filter box, will hold film and pull out, the fibre bundle section expands in box.
The present invention has illustrated a kind of new up-coiler with built-in bundle trimming, for the manufacture of with trimming hollow fiber membrane bundle section.Content of the present invention is up-coiler and method for winding, comprises automatically hollow fiber membrane bundle being transferred to new bundle finishing device.Described doughnut makes and is transferred to the slack adjuster of described new up-coiler in the fibre spinning machine by prior art.
Show ryce 7 at the embodiments of the invention shown in Fig. 1 and Fig. 2, the rotation of described ryce is perpendicular to the main shaft of ryce support 10, that is to say, the so mutual layout of the main shaft of the rotation of ryce 7 and ryce support 10, make for ryce 7 and always have plane perpendicular to the main shaft of ryce support 10, the rotation of ryce is distributed in this plane.The rotation of each ryce is to the distance of the main shaft of the ryce support radius of turn less than ryce thus, and this has realized a kind of compact especially arrangement form.For after the rotation of ryce support, the ryce of back occupies the position identical with the ryce of front in addition, and the rotation of these ryces is distributed in a common plane.The rotation of described ryce has the distance of the identical main shaft that arrives the ryce support in addition.Equal zero in this distance of the embodiment shown in Fig. 1 and 2, thereby the main shaft of the rotation of ryce 7 and ryce support intersects.
Show cylinder 10 as the ryce support at the embodiment shown in Fig. 1 and Fig. 2, described cylinder can support rotatably around main shaft.Rotatably mounted two are oppositely arranged ryce beam 7 on cylinder 10, and wherein the coaxial axis of ryce beam 7 is perpendicular to the main shaft of cylinder 10.Non-constant width ground winding mandrels 8 spaced apart from each other is arranged on the end of coiling beam 7, thereby the ribbon of carrying 5 is reeled by winding mandrels 8 when 7 rotation of ryce beam.
When winding process begins, in described coiling beam 7 one of the top of ribbon, preferably on one of two winding mandrels 8, keep securely by wired device (" top folder ").After reeling, its separation is fixed and then made to ribbon on one of two winding mandrels 8 by another wired device (" end folder "), wherein, the free end of ribbon 5, the top that is next fibre bundle keeps by shifting wired device 14, and the wired device of described transfer then is transferred to described ribbon another ryce beam 7 or its top folder.The separation of ribbon can be undertaken by the separator that is built in wired device.
At least two ryce beams 7 are bearing in can be on the cylinder 10 that rotation rotates, and wherein the rotation of ryce 7 is perpendicular to the rotation of cylinder 10.Can reel on a ryce beam thus, the second ryce beam that loads automatically is transferred to its fibre bundle trimming and processes quasi-continuously.Thereby realized quasi-continuous be connected (Verkn ü pfung) of spinning process with the hollow fiber membrane bundle trimming, particularly because the length of the fibre bundle of having reeled is longer than the length of the bundle section of making.By reeling, the doughnut of sensitivity there is especially the processing of protection.
Utilize the present invention, can be by producing simultaneously a lot of fibre bundle sections at the fibre bundle of reeling between winding mandrels 8 in an operation.Transfer process of the prior art can be saved.Ryce beam 7 can have the length of several meters.
New up-coiler is made for example several meters long of the fibre bundle 20(of the length that is longer than final bundle section here).Described bundle 20 is transferred to renovation process with its whole length and automatically uses the film 25 that holds from a spool to hold on whole length.Hold film 25 and for example automatically fix and after this, described bundle is automatically cut into by welding the bundle section that length is about 200-300mm.Hold device and be built in and movably hold in platform and can for example move to ryce beam 7 from the below or from the side, in order to admit bundle 20.By holding with film 25, bundle 20 has and connects rotund cross section.
Be about 0.4-0.5m/s from the spinning speed of spinning-drawing machine output long filament.Ryce beam 7 revolves to turn around on average needs 14 seconds.The speed of ryce beam changes, because at first reel in the starting that winding process begins by means of the filament length of slack adjuster 1 storage.
Ryce machine (when average filter size FX is 60) was produced the bundle section through holding and cutting in average every 9 seconds.By the suction bar realize bundle section through cutting from hold device taking-up and to the transfer of conveyer belt.Hold platform moves perpendicular to the suction bar for this reason.The suction bar is transferred to the section of bundle on conveyer belt.By means of the conveying of described conveyer belt realization from machine to other processing.
During to the ribbon of reeling by the spinning equipment supply, can relative position at cylinder on continue processing at the ribbon of completing coiling on another ryce beam when winding mandrels, that is to say, hold, weld and prescind with film.Also it is contemplated that on cylinder and to arrange more than two winding mandrels pair.This moment for example can a winding mandrels on carry out winding process, and simultaneously three other winding mandrels on carry out other trimming step, as holding, weld and prescind with film.But preferably only form two winding mandrels pair, thereby cylinder is always with 180 ° of beats operations.
As mentioned above, there is clamping device on each winding mandrels 8, in order to the top of new ribbon is clamped in (top folder) on winding mandrels securely.For this reason, swingable gripping bow moves and the end of ribbon is pressed on winding mandrels to winding mandrels.The top gripping bow holds with fiber when reeling.There is in addition same clamping device, so that the end (end folder) of fixing ribbon of having reeled.
Two winding mandrels 8 are arranged on the ryce head here, and described ryce head can be linearly mobile along ryce beam 7.Obtain thus one for stretching and the compression set of the fibre bundle 20 of having reeled, have normal position, stretch position and compression position when being shaped when reeling, this compression position is the final lengths when holding corresponding to fibre bundle.
When 7 rotation of coiling beam, ribbon 5 in the end is stretched on a deflecting roller 3 with very different speed, that is to say, ryce 7 is static in short time at two dead-centre position places, is elevated to maximum to be similar to sinusoidal skew curve between dead-centre position.Degree of tightness regulating wheel 1 is used for compensating this velocity perturbation, the correspondingly vibration (reciprocating motion) on its vertical axis of described degree of tightness regulating wheel.When the amplitude of the motion of degree of tightness regulating wheel surpasses upper extreme value or lower extreme value, lentamente the rotating speed of ryce beam is readjusted, until readjust constant stationary value (Beharrungswert).The level of the vibration of degree of tightness regulating wheel/highly preferred in the upper area of vertical axis 4.Thus, in the time of on the ryce of the sky below fully loaded and long filament bar 5 is transferred to when ryce 7, the degree of tightness regulating wheel also has enough capacity as buffer storage.
When utilizing weight G to apply required pulling force on degree of tightness regulating wheel 1 according to prior art, form spring mass system together with flexible ribbon, this system tends to occur natural frequency vibration in disadvantageous situation.Therefore suitable is to combine with common tooth belt driver to adopt as far as possible puller system without quality, for example the servomotor 16 controlled of torque.Described degree of tightness regulating wheel 1 designs gently especially in this case, thereby intrinsic frequency is obviously higher and can avoid resonant vibration.Servomotor provides constant torque, and described torque also can be readjusted according to the output signal of additional thread-tension measurement mechanism in case of necessity.Described degree of tightness regulating wheel 1 additionally can also not have during situation that pulling force is regulated is moved to fixing position, as suitable when the initial sum termination of winding process.
Here reel and carry out with following steps:
Initial position before initial:
Advanced in degree of tightness regulating wheel system (1,2,3) by the ribbon 5 that production equipment provides, and after this, in the end taken out by suction tube 13 between deflecting roller 3 and ryce beam 7.The degree of tightness regulating wheel is in fixing upright position for 1 this moment, does not namely apply pulling force.
Winding process begins:
Shifting wired device 14 grasps ribbon 5 and directly in the back that clamps the position, it is cut off above suction tube 13.Degree of tightness regulating wheel 1 switches to " pulling force " operational mode simultaneously.
The separated end of ribbon is sucked out, and the top of the ribbon of back is directed to the following winding mandrels of ryce 7 by the wired device of transfer, it is transferred to the top folder here.
In this transfer process, the ribbon material of supplying later is stored in slack adjuster during this period.
The ryce beam begins rotation, at first with the rotating speed rotation higher than normal speed of production.At this moment, the degree of tightness regulating wheel of vibration moves up gradually, until arrive the height and position of wishing.Regulate by amplitude monitoring recited above, the ryce rotating speed is now according to average ribbon Speed Reduction.
When reaching the rotating cycle of hope, the ryce beam stops at definite position, and by the clamping end of deciding ribbon of end.The ribbon material of supplying later is stored in again in degree of tightness regulating wheel device now.
Shift wired device 14 and now static ribbon 5 is cut off, keep securely formed free end, until with cylinder 10 Rotate 180s of fully loaded ryce °, press from both sides to the top of new empty ryce described end-transfer this moment, etc.
Breaking down or during at the coiling end-of-job, shifting wired device 14 and again ribbon is transferred to suction tube 13.
Obtain following advantage in up-coiler according to the present invention by this structure:
