In response to these problems, the use of PLC technology to design a lowcost, high efficiency materials automatic sorting device, material sorting process achieved good control effect. Sorting of materials using programmable controllers PLC control, continuous, large quantities of cargo sorting, sorting error rate is low and the labor intensity greatly reduced, can significantly improve labor productivity. Moreover, the sorting system can be flexibly connected seamlessly with other logistics equipment, to achieve real materials logistics, materials distribution and management of information flow. The design uses standardized, modular assembly, having a flexible system layout, maintenance, overhaul and convenient features, subject to site causes little impact. Meanwhile, as long as the object depending on the sorting, the system requires little modification can be realized. PLC control sorting device covers PLC technology, pneumatic technology, sensor technology, position control technology and other content, is the actual industrial field production equipment miniatures. Application of PLC technology bined with pneumatic, sensors and position control technology, the design of automatic sorting of different types of materials control system. Strong flexibility of the system, program development easy sorting of materials can be adapted to flexible production line requirements. This paper introduces the PLC control system hardware and software design, as well as some debugging methods. In this thesis, Mitsubishi FX2N series PLC sorting device for control system design. Main contents are based on the requirements in the process, the first advanced hardware system design, and then the ladder programming, and the key steps of the ladder explanation. Finally learning software in Mitsubishi PLC FXTRNBEGC simulation software for the simulation, the simulation results illustrate the correctness of hardware and software development.
