PLC在机械手控制系统上的应用

机械手在工业生产中得到广泛的应用,传统工艺中采用继电器控制时,需要的继电器多,接线复杂,因此故障多,维修困难,费时费工,不仅加大了成本,而且影响设备的工效。本文介绍了用日本三菱公司生产的F1/F2系列可编程控制器,根据机械手的运动规律:左/右、上/下、夹/松等进行软件编程。实现了手动操作,即:用按钮操作,对机械手的每一种运动单独进行控制;自动操作包括单步、单周期和连续操作。另外,对右工作台有工件的特殊情况进行了处理。采用梯形控制直观易懂,为电气人员所熟悉;采用PLC控制使接线简化,安装方便,而且保证运行的可靠性,减少维修量,提高了工效。

PLC IN MECHANICAL MANIPULATOR APPLICATION ON CONTROL SYSTEM

The mechanical manipulator is widely used in our industry producetine.In the past,the manipulator was controlled by relay,which needed a lot of relays and its connection is very complex,this brought us much trouble,made the manipulator hard to repair,and influenced the work efficiency of the equipment.So in this article we introduced the F1/F2 series programmable controller made by MITSUBLSHI Co.By the law of the manipulator movement which is left/right,up/down,tigh/loose and using shift registers to program the software,at last the article actualized the manipulator manual operation,single step operation,single cycle operation,continuous operation and dealed with special parts of workbench.A program in ladder chart given to control circuit made it easy to understand,the use of PLC made installation conveniently and steadily,the trouble with the manipulator is fallen down,then improved its working efficiency.
