This thesis mainly discussed the design of contrnl system of roll packing.As the kermel 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 Dongguan Jiaming Machine Manufacturing Limited Company 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 ments to work safely, high speed and efficiently, we designed the PLC correspondence network by using the WinCC, a supervise contrnl 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.
Key words:Packing machine; PLC; tension control; self-adaptive Control control; WinCC; Step7.
