Question 5 Four double acting pneumatic cylinders, namely A, B, C and D, are used to assemble a component in a production process. An electro-pneumatic circuit which are controlled by double solenoid valves is required for the application. The cylinder motion sequence is as below: Step 1. (b) 2. 3. 4. 5. 6. 7. 8. 9. à Description Initially cylinder A are in its extension state while cylinder B, C and D are in their retraction states. When a pushbutton (Normally Open type) is pressed momentarily, cylinder A retracts to its fully retracted position while B extends to its fully extended position simultaneously Next, cylinder B retracts to its fully extended position. Next, cylinder D extends to its fully retracted position. Next, cylinder C extends to its fully extended position. Next, cylinder C retracts to its fully retracted position. Next, cylinder D retracts to its fully retracted position. Lastly, cylinder A extends to its fully retracted position. System halts and await for another input signal to run the above cycle again. Other requirements: (i) Each step of motion can only be started right after the previous step motion ended (ii) Every cylinder motion is speed adjustable Reed switches or micro-switches or IR sensors, with NO and NC contacts, may be used for position sensors. (a) Group the motion sequence by the Cascade method. Draw the electro-pneumatic sub-circuit of the system. (c) By using the Cascade method, design an electrical ladder diagram for driving the above sequence of the four pneumatic cylinders.
