Abstract

The traditional separation methods using artificial detection, slow speed, low efficiency of existing material and human factors issues. With the increasing productivity, material for automated detection of inevitable. Based on the material analysis of the process flow, design based on the PC-PLC model material automatic sorting system of hardware of control system. Through the sorting system control system general scheme and working principle of introduction, elucidation of the control part of the hardware system design, completed the selection of hardware and software design, and through on-site commissioning verifies the rationality and reliability of the control system.
