Exercise 12
Co-ordinated motion control with auxiliary conditions
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. This is indicated by means of an audible signal. The control is to be operated in single cycle. Use a single solenoid directional control valve for cylinder 1A and a double solenoid directional control valve for cylinder 2A. A detent push button switch is used to replace the limit switch S3 on the input plate.

Transfer device for boxes
Problem Description
Two cylinders are used to transfer parts from a magazine onto a chute. When a push button is pressed, cylinder A extends, pushing the part from the magazine and positions it in preparation for transfer by cylinder B onto the outfeed chute. Once the part is transferred, the second cylinder retracts followed by the first.

Bending device
Problem Description
The bending tool is used to bend metal strips. The strip is inserted manually. After pressing the Start push button, Cylinder A clamps the workpiece, Cylinder B bends the part and returns to its initial position. Cylinder C completes the bending operation.
