Manual Palletizing Equipment for Stacking Bags on Pallets

Incline conveyor takes 50 Lb. bags of shelled corn up to a gravity roller accumulation table

One or more operators can use manual palletizing equipment to stack open mouth bags and valve bags containing a variety of agricultural products such deer corn, cottonseed hulls, oats, alfalfa pellets / cubes, soybean meal, barley, dried molasses, and mixing / stock salts. They can also stack bags filled with industrial products such as chemical powders, cement, mortar, and pigments.

Process Description

If you are filling open mouth bags, they first drop onto a closing conveyor, where the bags are closed using a bag sewing machine or heat band sealer.

If you are filling valve bags, they are automatically sealed and don’t require sewing.  The valve bags simply “tip-and-drop” onto a wire mesh bag discharge conveyor.

Next, if you need to turn, kick, or lay down bags, they move through a type of conveyor called a bag turner conveyor, or bag kicker.  This orients the bags in the correct direction before they move through the next set of conveyors.

Next, the bags are elevated using an incline conveyor.  If you need to remove air from the bags, they will instead move through an incline bag flattener conveyor.

Then, the bags arrive at the gravity roller conveyor or table, where an operator picks up a bag and carries it over to the palletizing station.

The shipping pallets can sit directly on the floor, or they can rest on top of an EZ pallet loader that automatically adjusts the height of the pallet to an ergonomic stacking height for the operators. When the pallets are full, a forklift operator will take the pallet away from the manual palletizing system and replace it with an empty pallet. If you have 2 palletizing stations, this will allow the operators to continue stacking bags while the forklift operator replaces the full pallet with an empty pallet.
