Design And Implementation Of White Paper Line PLC Control System

With the continuous development of the general printing industry,the technological innovation in the printing and coinage industry continues.At the same time that the printing equipment production related equipment has been updated,the preparation process has also attracted more attention.Banknote printing paper must go through a series of preparatory processes before printing,such as unpacking,punching,over-counting,etc.,still use the full manual operation form,transforming it into an automated assembly line can reduce manpower,improve work efficiency and reduce Error rate,etc.Based on this background and relying on Xi'an Banknote Printing Co.,Ltd.to carry out detailed demand analysis.The automatic assembly line is sealed,and the multiple manual processes that have been manually completed are integrated into one automation.This paper proposes to prepare the process of transforming the printing white paper into automatic flow operation,create the mechanical system of the whole linkage line,adopt PLC as the core of its control system,design the power supply of the total circuit,the electrical control method of each module and its auxiliary servo system.Air floatation system.Select all hardware including the PLC and its corresponding modules and configure the input/output point address.At the same time,the functions of each module are designed on the software flow,and the operation screen is completely designed.Subsequently,the debugging work of each module and the system joint debugging were carried out on the assembly line,so that the system finally realized its function and had good human-computer interaction.Finally,the faults that are easy to appear in the module are summarized and the corresponding processing methods are given to ensure the safe operation of the system.The white paper unpacking linkage line system has been put into use,which solves the problem of high efficiency and low error rate of printing white paper in the preparation process.It proves that the design of the research is good in actual production and proves that it is on the market.The feasibility of the application.Since the design is only a preliminary design,more in-depth research is needed in the completely automatic control,and the subsequent needs are continuously summarized according to production requirements,manual operations,etc.,and the inadequacies of the automation linkage line are improved.
