Abstract: An example pallet auto box with robot palletizer includes a conveyor to move a pallet into a loading area adjacent a robot for loading bags onto the pallet. The example pallet auto box with robot palletizer also includes an auto box having at least one wall, and in an example four walls, that can be raised and lowered. The at least one wall is raised as the robot stacks bags onto the pallet to maintain a border around the edge of the pallet for the bags to be stacked on the pallet. At least one wall opens as a door or gate after the pallet has been loaded with bags so that the loaded pallet can be moved out of the loading area and a next pallet moved into the loading area. The at least one wall is lowered again for stacking bags onto the next pallet.
