Abstract
A carriage is mounted for movement along a track situated above, and generally parallel to, the case conveyor. When the case reaches a predetermined location, conveyor movement is terminated and the carriage is moved along the track by a pneumatic cylinder. Affixed to the side of the track is a rack having a plurality of gear teeth. The teeth of a pinion gear, situated on one end of a shaft extending from the carriage, operably engage the gear teeth of the rack. In this manner, the gear is rotated in accordance with carriage movement along the track. A flap engaging disc is operably connected to the other end of the shaft and situated adjacent the top of the case. Movement of the carriage along the track causes the disc to rotate as it is displaced relative to the case. As it moves, the disc engages the leading flap of the case and pivots same to an opened position.
