  • Patent number: 6382400
    Abstract: A transport and position system, particularly for the workpiece transfer, has a lever mechanism between its driving motors and its output to carry out a step-up. The lever mechanism takes over the guiding as well as the driving of the carrier device which therefore forms the output of the lever mechanism. As a result of the step-up, high accelerations and decelerations can be achieved at the carrier device. Thereby, the mass inertia of linear guides for the bearing of levers and mass inertias of drives moved along play a substantially reduced role. While a high positioning precision can be achieved.

  • Patent number: 6374995
    Abstract: A positioning system (31, 32, 33, 34 35, 36), particularly for transporting and positioning workpieces, has a drive and force generating transmission device (47) by means of which a carrier device (41) can be moved and positioned. At least one force generating device (70) is connected to the drive and force transmission device (47), which force generating device (70) feeds into the drive and transmission system of the drive and force transmission device (47), an additional force used for compensating the weight of the drive and force transmission device and its moved parts and possibly of a workpiece, to the extent that this force manifests itself at the drives of the drive and force transmission device (47).

  • Patent number: 6374994
    Abstract: A transfer system, particularly for the transfer of workpieces in multi-station presses (1), consists of several transfer modules (14 to 19), which each have a workpiece holding device (28) which is carried by at least one lever mechanism (23). Each lever mechanism transmits the adjusting movement of two mutually independent drives (39, 44) to the workpiece holding device (28). One of the drives (39, 44) is disposed in a stationary manner, and the other is moved by the drive disposed in a stationary manner. This basic principle opens up many design possibilities.

  • Publication number: 20020035861
    Abstract: An orienting station provided particularly for press systems has a receiving device which is carried by a rod-type transmission. This rod-type transmission is supported on drive units of a driving device. The drive units are disposed in a stationary manner. The rods of the rod-type transmission are rigid and their lengths cannot be changed.
