  • Patent number: 5248236
    Abstract: A transfer system includes an air table, and a linear motor cooperating with the air table to float and move a pallet. The transfer system is designed to allow for a small radius of curvature for each turning section of the air table. Ball valves of the air table are openable upon contact with a pallet to apply air under pressure to a pallet. A linear motor is adapted to move the floating pallet, and guides are provided to guide the moving floating pallet. The pallet includes a pallet body made of a light material, and an external load part made of metal. The external load part has a lower surface projecting slightly from the lower surface of the pallet body. Guides are mounted to the outer periphery of the pallet body. A linear motor secondary conductor is mounted to the lower surface of the pallet body.
