Design of a sequential control circuit for an Industrial Robot using cascading method

Abstract

A sequential control circuit for an industrial robot is to Automation model using PLC program is also programmed and controlled by using Sieman simatic step win software. The be designed to transfer hot billets leaving a furnace to the die of a forging machine. There is no universal circuit design method that suits all types of sequential circuits. A circuit designer should be aware that his method is economical for particular applications. There are four methods to design a sequential circuit. They are Karnaugh Veitch map, step counter, combinational logic circuit design and cascading method. This paper helps to know how to design a sequential circuit using cascading method. The circuit has been simulated by using Automation studio 5.3, software. A model of the industrial robot performing the above said operation is in a sequence C+A+B+C-B-A-. The pneumatic supply is used to control the sequence of operation. Also a model of robot has been made. The robot functions as the above said sequence. Using PLC program, the robot operation is controlled. The sequence of operation controlled by PLC program is also simulated using Automation studio 5.3 software.
