Abstract
An automated pallet checker system for checking the structural integrity of a pallet includes a conveyor arrangement mounted on a framework and operable to convey the pallet to be checked through an in-feed station and a lift station connected to the in-feed station. The in-feed station is configured to check the pallet for a presence or absence of pallet bottom cross boards as the pallet is carried on the conveyor arrangement. The lift station is also configured to check for obstructions depending from the pallet bottom cross boards, and missing material in leading and trailing edges of the pallet top cross boards during a lifting movement of the pallet in the lift station. A controller is operatively connected to the conveyor arrangement, the in-feed station and the lift station, and is responsive to signals generated in the in-feed station and the lift station to determine whether the pallet being checked in the in-feed station and the lift station is acceptable or unacceptable.
