摘要： A shingle bundle palletizer includes a bundle metering conveyor, an incline conveyor, a pattern conveyor, a lug conveyor, an adjustable height transfer conveyor, a shuttle conveyor, and a pallet removal conveyor. The bundle metering conveyor includes one or more upstream and downstream belts. Each upstream belt is driven by an in-roller, variable speed motor that is independent of each downstream belt. The pattern conveyor includes a pair of outer pattern belts rotatably mounted on a pair of outer pulleys, and a center pattern belt rotatably mounted on a center pulley. The pair of outer pulleys is keyed to a pulley shaft and the center pulley is free-rotating about the pulley shaft to decouple the center pattern belt from the pair of outer belts. The pair of outer pattern belts and the center pattern belt are independently driven by separate motors and belts made of elastomeric material. The shuttle conveyor includes a belt made of an elastomeric material driven by a motor connected to a drive shaft. An encoder reads indicia on the drive shaft to determine the precise location of the shuttle conveyor during the reciprocation process.
