摘要：The manual process of manufacturing the welding electrode takes more time and work. It also occupies more space for the control panel with the installation of PLC in the welding electrode manufacturing control panel the size of the panel is reduced to the great extent. It has reduced the cost of the panel and has increased the rate of the production. Here the entire process of electrode manufacturing is done automatically. The contol panel includes three major controls. They are wire feeder control, extruder control and conveyor control. In the above PLC is used for the extruder control. The sequences of forward and reverse operations of the extruder are controlled by PLC with the suitable program fed in it. The wire feeder and conveyor are control with the help of contactor, timers and variable frequency drives by direct connections with the control panel. PLC is implemented for the control of conveyor process. The conveyor process panel consist of an OMRON PLC(12/8), SMPS, proximity sensors, MCB and relays. For application purpose light indicators buzzers, exhaust fan and a model showing conveyor process are used. Any sequence of operation can be performed on the light indicator, buzzers, exhaust fan and conveyor model by feeding suitable program on PLC. The PLC program of this project are done and executed in CX-programmer on real time basis.
