ABSTRACT:
A loader-unloader is disclosed which can controllably move a workpiece into and out of a workstation in a machine without danger to the machine operator. The loader-unloader has a table which supports the workpiece and aligns it with the workstation. A plurality of clamps are used to grip the workpiece. One clamp is provided for each part of the workpiece exiting the machine. The working faces of the clamps make point or line contact with the workpiece so that it can be moved slightly in the clamps under the influence of aligning means on the table and in the machine. The clamps lift the lower portion of the workpiece as it is moved toward the workstation to reduce frictional resistance and to prevent the lower portion of the workpiece from being scratched. In operation, the machine operator places the workpiece on the table and initiates the loader-unloader cycle. The workpiece is clamped and aligned and then moved forward into the workstation. The machine operates on the workpiece which is then withdrawn from the machine. The entire loader-unloader and machine cycles can be combined for automatic operation or can be individually controlled manually.
