Circuit Problem and Description: Using the given components, design two pneumatic circuit which will operate a single acting, spring return cylinder (A): 1. Direct Command: A push-button-controlled normally closed 3/2 way valve (M1) must be used to control a single acting cylinder so that, when the button is pressed, the cylinder moves out and, when it is released, the cylinder returns to the initial position. 2. Indirect Command: A single acting cylinder will be driven by the effect of a single air- piloted spring-return 3/2 way monostable valve. Activation by push-button of a normally closed 3/2 way valve will provide the signal to activate the valve moving the cylinder. The cylinder will move out when the push-button is pressed, and will move in when the user releases it.

For the following automatic control systems commonly encountered in daily life, identify the devices that perform the measurement (M), decision (D), and action (A) functions, and classify the action function as “On/Off’ or “Regulating” (time-varying until reaching a setpoint).

An industrial robot performs a machine loading and unloading operation. A PLC is used as the cell controller. The cell operates as follows: (1) a human worker places a part into a nest, (2) the robot reaches over and picks up the part and places it into an induction heating coil, (3) a time of 10 sec is allowed for the heating operation, and (4) the robot reaches into the coil, retrieves the part, and places it on an outgoing conveyor. A limit switch X1 (normally open) is used to indicate that the part is in the nest in step (1). This energizes output contact Y1 to signal the robot to execute step (2) of the work cycle (this is an output contact for the PLC, but an input interlock signal for the robot controller). A photocell X2 is used to indicate that the part has been placed into the induction heating coil C1. Timer T1 is used to provide the 10-sec heating cycle in step (3), at the end of which, output contact Y2 is used to signal the robot to execute step (4). Construct the ladder…

Design the electro -hydraulic circuit for the lifting and shifting operation as shown in Figure 2 with the following requirements. Following are the sequence of operation. Products are required to be transferred from lower level conveyor to higher level conveyor using two hydraulic Cylinders (Cylinder A and Cylinder B) and a conveyor belt (semi rotary motor) Cylinder A lifts the product on receiving it at lower level to the platform. Then, Cylinder B shifts the product from the platform to the conveyor, Then the conveyor motor should be rotated after 5 seconds to transfer the product to packaging Repeat the sequence of operation for 10 trials. NOTE: use independent DCV for each actuators (Cylinder A, Cylinder B and Conveyor motor)
