  • Patent number: 5423648
    Abstract: A method and system are provided for quickly and efficiently transferring a workpiece from a first work station including a first sheet metal press to a second sheet metal press by providing a pendulum-type robot, including an arm assembly mounted on a support structure to swing about a first axis located above and between the first and second presses. The arm assembly not only swings about a first axis but also rotates about a second axis orthogonal to the first axis and a third axis which is orthogonal to the second axis. During swinging movement of the arm assembly about the first axis, rotation of the arm assembly about the second and third axes allows a center of gravity of the workpiece to follow a substantially straight line path between the first and second presses. The arm assembly includes first and second four-bar linkages, which are pivotally connected together to rotate about the second axis. Preferably, a wrist mechanism is provided to permit rotation of the part between the presses.
