Research And Application Of Control System Of Automatic And High-speed Roll Packing Machine Based On PLC

This thesis mainly discussed the design of control system of roll packing.As the kernel device control system, PLC is widely used in modern industrial production and do well in this field.This thesis takes the control system of the high-speed full-automatic roll packing machine that was developed by Dongguan Jiaming Machine Manufacturing Limited Company along with us as a background. We apply the advanced control technique in the packing machine control system such as the technique of PLC, the inverter technique, light electricity technique and so on. By using these techniques, we realized tension control, Synchronous control in transmitting process and packing process program control. To complete the data of collecting and control the output equipments to work safely, high speed and efficiently, we designed the PLC correspondence network by using the WinCC, a supervise control and configuration software of the company of Siemens, and its communication function, to realize the surveillance function of the packing process.The machine got the exaltation of the quality whether the function or the efficiency, basically came to the international advanced level in the late of 90's, realized well the control request that the company put forward.This control system is well running in the lab.
