Hi Guys,
I have an application i hope someone can help with.
First of all, all air cylinders are controlled by double acting valves.
I have a machine that picks up material from one pallet, and places it onto a conveyor. The part i am struggling with is working out logic for the pick and place. Pick up and drop off points to not change.
Basically the cylinder goes to the left, gripper goes down, gripper goes up,cylinder goes to the right,gripper goes down,gripper goes up,cylinder goes to the left.....and we just keep cycling like that until the switch is turned off. Need to remember valves are double acting....
Could someone please help me by sending me some handwritten ladder logic? Im not bad at PLC's but for some reason cant nut this out and im sure its pretty basic.......must be getting old!!
Thanks very much
