Abstract: [Objective] Material sorting is an indispensable link in industrial and agricultural production. Mechanized sorting can not only save costs, improve work efficiency, but also improve the accuracy of sorting. [Method] The author designed a simple, efficient and low-cost automatic sorting system, and analyzed the hardware and software structure of the system. The author selected Siemens S7-1200PLC as the control core of the material visual sorting system, comprehensively utilizing visual controllers, frequency converters, encoders, electromagnetic valve groups, sensors, high-speed counters, three-phase asynchronous motors, cylinders, and other equipment. The system was debugged using the Yalong YL-36A automation device as the control object. [Result] The system is able to recognize the color and shape of materials, realize the automatic sorting of different coloured materials, and can be used for real-time parameter monitoring, manual debugging or automatic operation through the human-machine interface. [Conclusion] The material visual sorting system runs stably, which is conducive to changing the traditional production mode, improving production efficiency, saving production costs, and achieving significant economic benefits. Therefore, large-scale modern automated material transfer and sorting, in line with the development trend of the times, is worthy of widespread promotion.
