  • Patent number: 5697753
    Abstract: A box stacker uniquely able to semiautomatically load, in place, inside a variety of enclosures, columns of stackable boxes, said box stacker being in the form of a movable structure that has a conveyor belt carrying structure attached thereto in a cantilevered fashion. The conveyor belt carrying structure has an inner end and an outer end and carries spaced boxes thereon to be stacked. A speed-up belt carrying structure has an inner end attached to the outer end of the conveyor belt carrying structure and receives boxes from the conveyor belt. A lift device automatically raises the conveyor belt carrying structure in predetermined increments to successively deposit boxes on a column or stack and a drive arrangement is coupled to the speed-up belt for driving the speed-up belt at a greater speed than the conveyor belt to eject the boxes from the speed-up belt onto the column or stack.
