ABSTRACT:
A lifting and stabilizing mechanism for an apparatus such as a bag elevator assembly for an automated filling machine having a stationary frame and a generally horizontal carriage mounted for vertical movement relative to the frame. The carriage is carried on a plurality of geared belts which each criss-cross the frame in an opposing "Z" configuration, and are alternately wrapped over and under opposed drive wheels and tensioning wheels rotatably mounted on the carriage. The opposing belts maintain the carriage in its horizontal orientation, and the drive wheels are rotated to provide the lift force for controllably raising and lowering the carriage. The drive belts are attached to and extend along vertical brace members of the frame using one of various clamping assemblies, and the vertical alignment of the carriage is augmented by a pin and channel guide assembly. Exact vertical linear registration or displacement of the carriage is accomplished by monitoring the revolutions of the drive wheels, drive axle, or drive motor, and comparing those revolutions to a predetermined chart or formula relating revolutions to linear displacement.
