   Automation (ENT 471) Laboratory Module UNIVERSITI MALAYSIA PERLIS 1   AUTOMATION ENT471 Session 2013/2014 Semester 1 Experiment No. 1 Design an Electropneumatic System  Name : ___________________________________________ Matric No. : ___________________________________________ Experiment Date : ___________________________________________ Report Submission Date : ___________________________________________ Received By : ___________________________________________ School of Mechatronics Engineering Universiti Malaysia Perlis     Automation (ENT 471) Laboratory Module UNIVERSITI MALAYSIA PERLIS 2 EXPERIMENT 1 Design a Pneumatic and an Electro-pneumatic System   Objective: To study on how to design and develop an Automation system using Pneumatic system and an Electro-pneumatic system, and understand the differences and the advantages among these two systems. Experiment 1(a) – Design a Pneumatic System using Pneumatic Training System Design a magazine clamping machine circuit with two cylinders based on below Machine diagram and descriptions. Figure 1. Machine diagram Process description 1.   When a push-button is operated, a pressure die-cast housing for a surveillance camera is fed from a magazine to machining station by a double-acting cylinder (1A) and clamped. 2.   A second, pressure restricted, double-acting cylinder (2A) then clamps the thin walled housing from a direction of 90 degree to the first cylinder. The completed clamping action is signaled by 2/3-way roller lever valves. 3.   When the machining of the housing is finished, a second push button is operated. This causes an unthrottled return stroke of both cylinders in the reverse sequence.   Automation (ENT 471) Laboratory Module UNIVERSITI MALAYSIA PERLIS 3a) List of LIVE (5) pneumatic components and its basic function. Component Name Function  b) Draw a pneumatic circuit based on your development circuit on the Pneumatic Training System.   Automation (ENT 471) Laboratory Module Experiment 1(b) – Design an Electro-pneumatic system using Electro-pneumatic Training System Product transfer on two level conveyors. Two (2) double acting cylinders (A and B ) are used to transfer product on two level conveyors system. Cylinder A will push slowly  the product upward when proximity sensor C detected upcoming part from 1 st  conveyor. Cylinder B will push slowly  the product to 2 nd   conveyor. Both end position for cylinder A and B is monitor by limit switch . The system will automatically ON  when START button is pressed and OFF when STOP button is pressed. Above operation can be translate to the Sequence diagram as shown in Diagram 1(a). 1)   Design Pneumatic and Electrical circuit for above system using ONLY  electro-pneumatic component. a)   Sequence Diagram Diagram 1(a)
