Abstract

Conveyor systems have been a mainstay of material handling for over 1 00 years. Conveyors are ideally suited to solving handling problem as a complete system rather than as a individual units. A complete conveyor system involves a combination of conveyors, accessories and controls the monitor and control the movement of material through the operation process. In this project is concerned with learning and exploring Grafcet and PLC as programming tooL The programmable logic controller (PLC) was becoming more powerful and high technology that extensively used in automation works. Thus, an efficient approach which can represent the control process by using the graphical representation perhaps a good solution to helps the designer in order to programming the PLC' s. There has been a growing interest in programming languages for PLC's. In order, the sequential function chart (SFC), an international standard based on the GRAFCET language was introduced in 1977 at France. The GRAFCET language has been used as one of the most important means for designing, programming and describing logic sequential control system. This powerful graphical language dedicated to the specification of the behavior of sequential logical systems. It is standardized by CEI and its semantic is defined for this type of applications. The GRAFCET is a very good tool for logic controller specification, and the graphical nature of the language makes GRAFCET easy or simply can learn and implement or use in automation works especially in company site. In this conveyor system it is easy to handling material because a part of conveyor in this system is can move up and down. It is suitable to handling material or product from one plan to another plan.
