I have two pallets being unloaded onto two conveyors by one operator. The pallets are on a separator located at the end of their respective conveyors. I want one operator to unload 6 boxes from one pallet and then move to the other pallet and do the same and then alternate back and forth until empty. The operator will then move the pallet to a queue and a fork truck will deliver a new pallet and the sequence will continue.
