Abstract: A device and method for filling open boxes, containing such products as electronic equipment, with loose fill. The boxes are fed one at a time to a conveyor in random order. A bar code applied to each box, giving the box size, is scanned. The boxes are longitudinally centered by electric eyes actuating a brake at a centering station along the conveyor. The boxes are then widthwise centered by a pair of successively actuated cylinders. A pump-up cylinder at the centering station is actuated to lift a centered box to a predetermined height set by said bar code. A fill valve for loose fill has a supply of loose fill at its upper end fed to it through a feed pipe by gravity, the loose fill flowing by gravity, once the valve is opened, until its feed pipe is plugged, and then it is shut off. The pump-up cylinder then lowers the box to the conveyor. A series of air-blasts, sent to the box further along the conveyor, levels any mountain of loose fill that forms during the feeding of the loose-fill.
