UNIVERSITI TEKNOLOGI MARA FACULTY OF MECHANICAL ENGINEERING ________________________________________________________________________ Program : Bachelor of Engineering (Hons) Mechanical EM220/221 Course : Robotic and Automation Code : MEM 665 ________________________________________________________________________ CASE STUDY: TRANSFER STATION (Automation Lab) OBJECTIVES 1. To design and realize coordinated sequential motion control with auxiliary conditions 2. To enhance the performance of the transfer station with students’ creativity. 3. To work effectively in a multidisciplinary team

ELECTRO PNEUMATIC SYSTEM

Problem description Using a transfer station, blocks are to be transferred from a magazine to a processing station. The blocks are pushed out of the magazine by cylinder 1A and transferred to the processing station by cylinder 2A, the piston rod of cylinder 2A may only return when the piston rod of cylinder 1A has reached the retracted end position. The magazine is monitored by means of a limit switch. If there are no more blocks in the magazine, it is not possible to start the cycle. The control is to be operated continuously and can be stopped at any time. Include any other performance enhancement of the automation system.
