Design of the control system of automatic picking and conveying line based on PLC

Automatic picking and conveying line is used to automatically transport work bin in spacecraft assembly warehouse. The hardware composition and control system design of automatic picking and conveying line is present in this work. The system consists of robot, automated containers, and conveyor lines. The control system of automatic picking and conveying line has three level control structures: computers, PLC, and actuating mechanism. The SIEMENS S7-315 PN/DP PLC is used as the slave computer to control the conveying line, clamps, sensors and other actuators. The system can implement many batches of work bin delivered into and out of warehouse.
