ABSTRACT:
The present invention is directed to a conveyor system adapted to transfer palletized loads along a generally horizontal path under the force of gravity. In one preferred form, the conveyor system of the present invention includes a support structure which generally extends horizontally from an input end to an output end and includes an upwardly facing support surface for supportively engaging a load, such as a palletized load. A longitudinally extending ramp member includes an upwardly facing portion and is pivotally attached to the support structure for movement between a first position and a second position. When in the first position, the upwardly facing portion declines as it projects forwardly toward the output end. When in the second position, the ramp portion declines as it projects rearwardly toward the input end. The ramp member preferably includes two sides which are each angled from the horizontal. The sides are preferably disposed at an angle of approximately 45 degrees with respect to a horizontal plane. The conveyor system further includes a skate assembly moveable supported on the ramp portion for movement between an advance position and a return position. A drive arrangement cyclicly pivots the ramp member between the first and second positions.
