The Design Of Control System Of BL300 Vertical Food Packing Machine Based On PLC

This thesis mainly discussed the design of control system of food packing.As the kernel device control system,PLC is widely used in modern industrial production such as tea ? medicine and chemical industry and do well in this field.The material is composite and agglutinate at high temperature.This thesis takes the control system of the BL300 full-automatic food packing machine that was developed by Hefei Baozhuangyuan Machine 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,light electricity technique and so on.This article mainly introduces the principle and course of the design,and the author calculates the parameter of the transmission system.This machine is mainly made up by the thwart and the vertical frame,the transmission system,shearing structure and electric control system.It can make bags?filling ?cutting and printing the date.This thesis summarizes the status quo of PLC and application prospects and possibility of packing machine.By understanding the production process of the full-automatic food packing machine,we optimize and improve the mechanical part,then add up the I/O points,and design the PLC control system.Using configuration software to realize touch screen control.Experimental study on prototype.According to the prototype testing we analyze data to find the best packing parameter values,verify the packing accuracy and speed,measure and calculate degree of reliability of the prototype.The machine got the exaltation of the quality whether the function or the efficiency,realized well the control request that the company put forward.
