PURPOSE:To carry pallets efficiently in an automatic working line employing robots, by performing working at the feed/return sides of pallet to be fed along a guide rail then returning said pallets through going side to returning side. CONSTITUTION:Two lines of rail 2, 3 are laid respectively above and below the machine frame 1 while elevating mechanisms 4 having independent short rails 2', 3' to be matched with each rail 2, 3 are provided at the opposite ends. A pair of guide rolls 6 are projected from the lower face of pallet 5 to hold one 3 of said rails 2, 3 from the opposite sides thus to guide the pallet 5. A friction sprocket 17 is provided to the pallet 5 to geared with a chain 15 sliding in a groove formed in the upper face of rail 3 thus to move the pallet 5 and to stop the pallet 5 through function of a stopper 18 while idling the friction sprocket 17. |
