Application of PLC in Material Automatic Sorting System

Abstract

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.

Design of Automatic Sorting System of Workpiece Based on Multi-sensor Detection

“…In the automatic production line, the PLC control is generally adopted, which has the advantages of strong resistance to interference, low requirement to environment, high reliability, simple program and the like. Many production lines are related to the classification and processing of items, literature [5][6] proposed the workpiece sorting system composed of PLC, frequency converter, etc., but haven't come up with good solutions to the software design, literature [7][8] proposed visual assistance sorting method, but the visual equipment cost is high, and the algorithm is trouble, literature [5][6] proposed two kinds of automatic sorting system for special purposes. In this paper, a simple and practical automatic sorting system is designed for general situations, the system solves several problems encountered in the establishment of automatic sorting system, and puts forward a scheme based on multi-sensor detection.…”
