Design of a PLC-Based Automatic Separate Channel Filter Rod Sampling Detection System

DF10 filter rod forming machine produced by Italy GD Automatic Machinery Ltd is the world's fastest filter rod maker adopting the design of dual-channel. To achieve automatic sampling detection on line, a PLC-based automatic separate channel filter rod sampling detection system has been designed. Mainly composed of a sampling and launching device, matching tube, receiving device, a test instruments, PLC control unit and data terminal, the system first samples the filter rods from the two channels, then launches them into the test instrument to measure their physical parameters, and after wards send the real-time feedback of testing data to the data terminal. The application results show that the system has the advantages of convenient operation, high stability, safety and reliability. With an effective batch’s completion rate above 98%, it greatly reduces the labor intensity of operators and QC personnel, and significantly improves the quality control capacity of filter rod production.
