ABSTRACT:
A control apparatus is provided for properly positioning an empty case on an elevator platform of an article loading machine having a conveyor for moving the empty case onto the elevator platform to be raised thereby to a loading position beneath a loading mechanism, a clutch and brake arrangement for intermittently controlling the conveyor, and hydraulic or pneumatic means for raising and lowering the elevator wherein the control apparatus comprises a cam means having a first position abutting a front end of the case when transported onto the elevator platform for physically stopping the case and for sequentially de-actuating the clutch, and actuating the brake for stopping the conveyor and for actuating the hydraulic means for raising the elevator platform. The cam means has a second position below a bottom surface of the case when loaded and lowered to an original position for actuating the means for starting the conveyor while providing a roller surface over which the loaded case is moved. The control apparatus thus provides proper alignment and positioning of the case on the elevator platform to prevent mis-loading of articles in the case and malfunctioning of the loading machine when the case is raised to the loading position.
