Abstract
The design of an automatic sorting device with low cost and high efficiency is presented in the paper which regards programmable logic controller (PLC) as the master controller and combines pneumatic device sensing technology and other technology to implement automatic selecting of the products. The device is characteristic of high automation, steady running, high precision and easy control .It can be continuous, large quantities of goods are sorted, sorting error rate low ,greatly reduce labor intensity, can significantly increase labor productivity. Furthermore, the sorting system would be flexibly and seamlessly connect to other logistics equipment. The design use of standardized and modular assembly , a flexible system layout, simple program development and easy maintenance. It adapts to elasticity production line for materials sorting. The system affected by the venue and other factors with little impact. Meanwhile it can fulfill different requirement according to different situations with little modifications.
