Abstract
The operations of the palletizer are automatically controlled by a prerecorded control program. The palletizer includes a vertical shaft, a retractable draw plate located above the shaft and a drive mechanism for moving a hoist along the shaft. After a tier of cartons is formed on the unretracted draw plate, a tier sheet inserter extracts a single tier sheet from a stack and places the sheet on top of the tier. The draw plate is then retracted, placing the tier on the hoist and the hoist is lowered until the tier is aligned with the banding mechanism, which is located within the shaft. The banding mechanism places a strap around the tier, tensions the strap and fastens same. The hoist is then repositioned to accept the next tier as same is deposited thereon by the draw plate.
