  • Publication number: 20040202531
    Abstract: An automated system for handling material and parts cut therefrom. The system includes means for unloading a material pallet positioned on a shelf within a first storage device and loading the material on a movable cart, transporting the material to an unloading station wherein the material is positioned onto a first shuttle table, the shuttle moving to a laser cutting station, unloading the cut material from the cutting station after parts are cut in the material, and transporting the cut parts on a pallet to a selected shelf in a second storage device using movable carts. The skeleton material remaining after the cutting operation is collected for eventual disposal. A second shuttle table is used to prepare additional material for cutting after the material brought by the first shuttle table is moved to the laser cutting station.

  • Patent number: 5913468
    Abstract: An improved method and device for separating parts from the sheet metal carrier. In particular, a single sheet from a stack of sheets having parts micro-joined to the carrier sheet is transported to the nip of a pair of pinch rollers. The pinch rollers move down to engage the front edge of the sheet, the pinch rollers moving the sheet to the nip formed between a pair of main rollers. The main rollers then move together to the drive position and transport the sheet to a separation device on the opposite side of the main rollers. The main rollers drive the sheet material in a manner such that the top surface of the leading edge of the sheet metal is engaged below the forward tip of the separation device. The separation device is then moves downwardly so that the upper surface of the separation device assembly is level to the part pass line.
