Hi Guys,
I've got a little problem that's puzzling me a little.
I'm installing an automated production cell we obtained from another company and by the looks of things i've got to completely rewire the cell and re-do the PLC program as we have no drawings available for any of it. The problem is this
We are using a roller conveyor to transport full pallets out of the cell, the roller conveyor entrance to the cell is to be protected by a light barrier. Obviously the light barrier will need to be muted when a pallet is leaving the cell but generate an E-stop condition at any other time. How do i stand with doing this from a safety perspective? I was thinking something along the lines of using a Pilz E-stop relay driven from the output controlling the outfeed conveyor and using that to loop out the light guard monitor temporarily the only downside is that the robot will still be working within the cell while the pallet conveys and I cant get around this as it would be detrimental to the cycle time and product quality.
What would you guys recommend?
