Abstract: A loading and unloading apparatus, in particular for the loading and unloading of presses, comprises a horizontally extending arm which is arranged on a carrier and which is moveable in the direction of its longitudinal axis and also vertically, and which has a gripper device for the parts to be handled. For the acceleration of the loading and unloading procedure, the arm is horizontally moveably guided relative to the carrier, and the gripper device is arranged on a gripper carriage guided on the arm, with the gripper carriage being moveable between the two ends of the arm.

Abstract: A portal system is described which consists of two translational axes and two rotary axes which are so arranged and controlled that every point within a cubic working space can be computed and reached. As a result of this special kinematic construction the total complexity for the frame and also the mechanical complexity and cost are substnatially reduced in comparison to customery portal systems.
