ABSTRACT:
A longitudinal conveying system for mechanically feeding one or more workpieces to a predetermined loading position, comprising a pair of spaced, parallel longitudinal workpiece supports, with each such supports including an upper support face and having a distal end and a proximal end. The predetermined loading position is located adjacent the proximal end of the workpiece supports, and a longitudinal conveying beam is moveably located intermediate the workpiece supports. The conveying beam has an upper surface for supporting one or more workpieces. Driving apparatus for moving the conveying beam in an upward direction, a forward conveying direction toward the proximal end, a downward direction, and a backward direction is provided for enabling the conveying beam to lift workpieces from the workpiece supports for movement toward the proximal end. The downward movement is substantially vertical, and the upper surface of the conveying beam is lowered below the upper workpiece support faces prior to the backward movement returning the conveying beam to a predetermined original position. A device for detecting when a workpiece on the upper surface of the conveying beam has reached the loading position is provided, and the conveying system includes a control device, for automatically varying the length of stroke of the forward movement of the upper surface so that the detected workpiece can be properly placed at the loading position by the downward movement of the conveying beam.
