  • Taco shell nesting apparatus and method
    Publication number: 20080041695
    Abstract: The present invention is, in one embodiment, an apparatus for placing an insert within a nested group of taco shells. The insert placement apparatus comprises a vertical shaft, a horizontal shaft, a first pillow block, a second pillow block, a vacuum cup, a horizontal timing belt, an air cylinder, and a servomotor. The vacuum cup is adapted to transport the insert. The first pillow block has a bore therethrough for receiving the horizontal shaft. The second pillow block is supported off of the first pillow block and has a bore therethrough for receiving the vertical shaft. The vacuum cup is suspended off of the vertical shaft. The horizontal belt is routed around a drive pulley and a second pulley and is interconnected to the first pillow block. The servomotor is interconnected to the drive pulley. The servomotor causes the timing belt to displace the first pillow block along the horizontal shaft, thereby causing the vacuum cup to displace horizontally.
