This article describes an input crane station which controls and monitors the incoming side of flowracks in an automatic crane control system. The input crane is primarily driven by a laser, when the laser determines that a new pallet of parts has arrived at the pick-up station. Then the input crane goes to work. When a scanner detects a new pallet, a program will verify that the pallet number has previously been "assigned" by the receiving station controller and that the part number inhibit is not true for this part. If there is a laser "read- error" or any of the above checks fail, an alarm will sound to summon human intervention. (Image Omitted) When the pallet is accepted, the program will examine the part record associated with the pallet to see if a latest location index currently exists for this part.
