Design of Multisensor Material Automatic Sorting System Based on PLC Control

研究基于PLC控制的多传感器物料自动分拣系统的设计,采用三菱FX-2N系列PLC承担其主要程序控制任务,同时,对传感器技术、变频器技术、电磁、气动、触摸屏技术等进行了系统综合,采用模块化设计,每一个工作单元可以独立设计,自由组合实现不同的系统功能。在对物料自动分拣系统功能需求的基础上,基于PLC提出电气控制系统的总体方案,设计实现整个系统控制部分与机械动作部分合理连接适配。设计的整个系统具有控制精度高、操作简便、可靠性高等特点,各项性能指标均达到设计要求。

The research of this paper is based on the PLC multiple-sense for automatic sorting system, this re- search adopts Mitsubishi FX-2N Series PLC to undertake major program control tasks. At the same time, sensor technology, frequency convertor technology, electromagnetic technique, pneumatics technique and touch screen technology are systematically integrated, the design of this system, employs modular design and each working unit can make design independently and achieve different functions. On the basis of the needs of auto sorting, this paper posed a scheme of electrical control based on PLC, with an aim to realize reasonable connection between systematic control and mechanical action. Reasonable connection and matching between controlling and mechani- cal action was achieved in this paper based on the auto sorting function requirement and the electrical control sys- tem design of PLC. The designof this system has characteristics such as high precision on control, easy and simple operation and good reliability and that all performance indexes have achieved the design requirements.
