PLC在材料自动分拣系统中的应用

为解决人工分拣货物劳动强度大、效率低等缺点，以PLC为主控制器，结合气动装置、传感器、位置控制等技术，运用梯形图编程，实现对铁块、铝块及不同颜色材料的自动分拣。系统具有自动化程度高、运行稳定、易控制的特点。并可根据不同对象，稍加修改本系统即可实现要求。

Application of PLC in Automatic Sorting System

To resolve shortcomings such as high intensity and low efficient about man-sorting goods,PLC was the master con-troller in the paper,and combines pneumatic device,sensing,Position control technology,program with the ladder-shape figure,designing the automatic system that sorts out iron,aluminum and plastics and different colour.The device is characteristic of high automation,steady running,easy control,which can fulfill the requirement according to different situations with little modifications..
