Design and Application of Automatic Material Sorting System Based on PLC Control

In order to speed up the sorting speed, reduce the intensity of manual labor, this project designs an automatic material sorting system based on PLC control. The system takes Siemens S7-1500 PLC as the controller, and completes the software and hardware system design of six workstations in the assembly line. The system realizes the processing, assembling and sorting of cylindrical materials through feeding unit, handling unit, processing unit, handling and installation unit, installation unit, sorting unit. At the same time, the project has developed a HMI human-machine interaction system. After debugging, the system can automatically sort different color materials and achieve the expected function.
