![Consider a pneumatic transferring station shown in Figure Q.3, where two cylinders are
used to transfer parts from a lower deck to upper deck of conveyors.
Cylinder 2A
Cylinder 1A
Eject
(b) Draw the displacement step diagram of the two cylinders.

Figure Q.3
The operation can be described by the following steps:
Step 1: Cylinder 1A extends.
Step 2: Cylinder 2A extends.
Step 3: Cylinder 2A retracts.
Step 4: Cylinder 1A retracts.
Step 5: Repeat Step 1.
The limit switches are used to detect the presence of parts on cylinder 1A and to monitor
the positions of the piston rod of cylinders. The process will only start when a part is
detected on cylinder 1A.
(a) Determine the sequence of movements of the two cylinders for Step 1 to 5.
(e) Sketch a pneumatic circuit of the system if all the cylinders are of double acting
cylinders and all the DCVs are of 4/2 double solenoid valves.
(d) Design an electrical circuit diagram using direct control technique to control the
transferring process.
(e) Use an appropriate diagram to explain the working principle of one-way light barrier
typed optical proximity sensor.
(f) Redesign the electrical circuit in (d) by incorporating non-contact sensing for piston
position detection using optical proximity sensor.
(g) A problem has arisen in the operation above. The Step 1 takes place, but the Step 2 does
not. Identify two possible problems and suggest a solution for each problem.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F2529541c-7791-4d3d-921d-6b7cc9f32d17%2Fcc114444-a1b8-4d8e-93b0-28c90ee33217%2F8fdhi89_processed.jpeg&w=3840&q=75)
