摘要： In a pallet supply apparatus, pallets are stacked on a loaded pallet elevator and are conveyed by the elevator to the upper end position of a main body of the pallet supply apparatus. The uppermost pallet is separated from the remaining pallets by a shutter. A left side flange of the pallet is pushed by a left roller in a direction to approach rear and side reference surfaces, and a right side flange of the pallet is then pushed by a right roller in a direction to separate away from the side reference surface and to approach the rear reference surface, thus positioning the pallet. When all works are picked up, and the pallet becomes empty, the right and left rollers are escaped, and thereafter, the pallet is slidably moved toward an empty pallet elevator.
