Title The design of pneumatic conveying test system based on Microcontroller-Structure design of conveying system

Abstract Pneumatic technology is a use of compressed air as the working medium to transmit energy and signal,achieves industrial automation technology with the microcomputer or industrial computer and the corresponding software.Because of its unique advantages,it is widely used in the fields of machinery,electronics,light industry,chemical industry,food, packaging,printing and so on.

This topic is a pneumatic conveying system structure design,including the overall layout of the structure,choose the implementation of components, solenoid valve according to the standard components provided by the manufacturer,design and installation of non-standard structure fixed desired pieces,use AutoCAD to draw 2D part drawings and assembly drawings, use Solidiworks to draw 3D parts drawing and assembly drawing,complete the action sequence according to the actual needs of the design;then select suitable programmable logic controller (PLC),According to the choice of the implementation of components and electromagnetic valves,drawing PLC circuit wiring diagram,finish the PLC program in accordance with the action sequence . After the completion of the overall design with manual single step,back to the origin, single cycle and continuous cycle of operation mode,fully applicable to teaching,mass production and so on.

The system has high reliability,high positioning accuracy,bear large load,simple pneumatic circuit,low cost,strong adaptability,can be widely used in industrial practice which requires monotonic and frequent handling products.

Keywords  Pneumatic technology,convey,structure design,PLC
