The Design of PLC in Electronic control
System of Punching Machine for Ceramic tile
ABSTRACT:Punching machine for ceramic tile is the important equipment in the tile production.The punching machine is composed of the monitor ,hydraulic control system , electronic control system and the attaching control system.This paper especially discussed the electronic control system which is based on PLC. The hardware and the software will be introduced separately. In the hardware part,firstly the electronic control principle would be analysed, including main circuity and control circuituy . Then the type of the electronic components should be elected and checked .In this part,selecting the PLC is most important.And the function of input and output terminal should be analysed also.In the software part,we should analyse the work flow,whicj included automatic、handed、circulativ and single working pattens .The paper introduced the programmes of every parts. The method of resisting interference is presented. And there is a instruction of how to run the system
