ABSTRACT:
An automatic material loading, positioning and unloading system is disclosed in connection with a machine tool turret punch. The device includes a loader which receives a stack of sheets to be fed to the punch machine. The loader includes means for lifting the sheets one at a time from a storage area, means for transporting the sheets to a loading area of the punch worktable and means for unloading the sheets at the worktable area. The punch machine includes automatically controlled workpiece grippers which receive the sheets from the loader, properly position them with respect to the machine tool, move them in a predesired sequence through the machine and transport them to an unload area of the worktable. The unload area of the worktable is effective to discharge the punched sheets from the machine to an unload stacker. The unload stacker receives and stacks completed sheets. The loader, grippers, turret punch, unload area and unload stacker all cooperate together to provide a fully automatic machine tool device capable of operating under automatic control to process a large number of workpieces one at a time.
