Abstract

An improved case packer machine is disclosed, of the type where containers are dropped through grid fingers to an empty case positioned on a lift table. The case packer machine of the present invention includes a flap opener which includes a pair of shoes mounted to an air cylinder. The shoes are extended by the air cylinder to contact and open the leading flap. The lifting table of the present invention is motor driven and controlled to limit the shock loading experienced by the containers as they are positioned within the cases. The lifting table includes a pair spur gears driven by the motor in meshing arrangement with a pair rack gears each mounted to a table and a novel gear guide to maintain proper engagement between the racks and gears and further to provide for backlash adjustment between the gears.
