Double acting Cylinder Forword/reverse operation using PLC.

 Double acting Cylinder Forword/reverse operation using PLC.           

This is the PLC program for double acting cylinder operation using PLC.                                                              

Although writing a PLC program in Double acting cylinder is a highly technical process, it can be understood in simple language:

Problem Description: -

We need to operate double acting cylinder using PLC. Write the PLC program using ladder diagram language and draw pneumatic circuit.

 

Problem Diagram: -

Solution: -

Here we need to operate double acting cylinder with PLC. As show in figure we took two push buttons for forward and reverse operation. PLC is used to control the outputs. We used double solenoid direction control valve for forward and reverse operation of the cylinder. Once user will press forward button, cylinder will move forward and if user presses reverse button, cylinder will move reverse.

Here we used PLC for output control so need to write program in PLC according to application.

 Program

Here is PLC program for making forward/reverse cylinder operation using PLC.

 

List of Inputs/Outputs

List of Inputs

X0: -Cylinder Forward

X1: -Cylinder Reverse

List of Outputs

Y0: -Cylinder Forword

Y1: -Cylinder Reverse

 

Ladder Diagram for forward/reverse operation of double acting cylinder.

Program Description: -

-        In first rung we have used NO contact of the Cylinder forward push button (X0) so Cylinder forward (Y0) output can be operated with the forward push button (X0).

-        In first rung we have used NO contact of the Cylinder reverse push button (X1) so Cylinder reverse (Y1) output can be operated with the reverse push button (X1).

Making application to move block from the magazine feeder to conveyor using pneumatic system.

Making application to move block from the magazine feeder to conveyor using pneumatic system.

Problem Description: - There is one conveyor system. Single acting cylinder should start if user press bush button and block should move form magazine feeder to conveyor system for next process. 

Problem Diagram: -

Solution: -

Here we can consider single acting cylinder, take one spring return bush button to operate singly acting cylinder. Push button will work as 3/2 bush button valve. If bush button is pressed, cylinder will operate and move the block and if it is released, cylinder will back to its original position. 

Pneumatic circuit: - 

Pneumatic circuit explanation: -

Here we can see in the figure single acting cylinder with spring return. It can push block when required and it can come back with spring force if bush button released. Connect pneumatic pipe from A to cylinder in as shown in figure.

We took 3/2 bush button so in normal condition air will pass from A to R as shown in figure, so cylinder is in normal condition. If we press push button, air will pass from P to A so cylinder will move. Connect Main air line in Port P of the 3/2 push button.

If we release push button air will not pass from P to A so due to spring force it will come back.
