Bag palletizing equipment generally consists of two L-shaped stacking frames to perform bag palletizing operation effectively. The frames serve as a backstop against which the operator can throw the bag, while at the same time ensuring a vertical orientation for the unit load. The use of two frames ensures that the operator can continue to work in one of them while the forklift is removing the load from the other, thus allowing line operation to continue without delay. Empty pallet dispensers are often incorporated into mechanically assisted bag palletizing equipment in order to eliminate the time and effort required for handling empty pallets.
