Application of PLC in Material Automatic Sorting System

摘要

In this paper a PLC control system is designed to control the sorting, transmission and loading/unloading in the manufacturing, in view of the defects of the relay control system which usually has poor reliability and bad flexibility in use. On the basis of the superior performance of PLC control system and the working principle of frequency converter, AC transducer drive technology is applied to achieve stable starting, reliable operation and low breakdown rate in the assembly line of manufacturing. In the design of the upper monitoring system, the functions of parameter settings, process monitoring and control, data processing, fault location can be well implemented via configuration software. The research work of this paper will lay a solid foundation for the design of material automatic sorting system based on the PLC controller.
