  • Device for the transport of carriers from and to a positioning device and selection device for use in such a device
    Patent number: 5085553
    Abstract: A device for the transport of carriers (11,29), in which displaceable containers (27,31) with carriers (29,11) can be coupled with a selection device (33), which is displaceable in vertical direction along a container (27,31) and has two relatively vertical positions with respect to the container (27,31) for the transport of carriers (11,29) at a bringing stage and at a fetching stage, respectively, from and to a positioning device R(B), R(C). The selection device (33) for use in the transport device as described. Use of the transport device with selection device lies particularly in the field of the flexible automation.

  • Manipulator with rod mechanism
    Patent number: 4874286
    Abstract: The invention relates to a manipulator comprising an end effector (27) displaceable by means of a rod mechanism comprising four arms (11,13,15,17). By means of simultaneously activated individual drives (29,35) for two of the arms (11,15) which are of equal length, which individual drives are integrated in a differential drive, a displacement of the rod mechanism is obtained in a plane at right angles to a main axis (3) about which the two arms (11,15) are rotatable. At the same and oppositely directed angular velocities of the arms (11,15) about the main axis (3), a radial (R) positioning of the end effector (27) takes place, while at the same angular velocities of the arms (11,15) in the same direction an angular (.theta.) displacement of the end effector (27) about the main axis is obtained. The manipulator is particularly suitable for use as assembling robot.

  • Driving mechanism and manipulator comprising such a driving mechanism
    Patent number: 4872362
    Abstract: A driving mechanism having a spindle which is provided with a first helical threaded portion having a lefthand direction of rotation and with a second helical threaded portion having a righthand direction of rotation. A pair of spindle guides each engage a respective spindle threaded portion for rotating the spindle and translating the spindle in an axial direction. Each spindle guide has three pairs of runner rollers on a sleeve for centering and supporting the spindle within the sleeves. The three pairs of runner rollers on each sleeve kinematically constrain the six degrees of freedom of the spindle without overconstraint to reduce friction and binding of the spindle in the spindle guides.
