Hi guys,
We have recently purchased a Fanuc robot which will be arriving in about two months time. It has been specced with the Profinet option and we intend to use it with a Siemes s7 1200 PLC. This robot will be installed in Multi-station welding cell.
My biggest question at the moment is what would be the best method of calling the individual programs. There are going to be 6 stations split into two loading sides. (3 different jigs per side). Only one jig per side will run at a time. So for example jig 1- station 1 and jig 4 - station 2 in tandem. This is to allow the operator time to load one side as the robot welds on the other and so on...
There shouldn't ever be more than two jobs in the queue at a time, but they should atleast be able to queue a second job while the first is busy welding. As far as I know the only option that allows queuing is RSR's?
The other issue is that they would like to have the option to change the jigs depending on the needs of production. In other words they would like to take the jig off of station 1 jig 1 and place a second jig in it's place. That's why I would prefer for each jig to have it's own individual "Program" and no rely on DI's and jump logic to accomplish a similar thing. it's just too messy. So using RSR's in this case would be a problem as they only come with 8 of them if I'm not mistaken?
If anyone has any suggestions or ideas, I woul love to hear them.
