  • Patent number: 4786227
    Abstract: The apparatus of the present invention utilizes a bricklaying robot which comprises an automatic brick-handling or grabbing device fastened to the end of a main arm which is carried by a frame mounted on a work platform; and which is radially movable relative to the platform. Circular movement of the arm and of the grabbing device relative to the vertical axis of the work platform is generated as result of a rotation of the platform about this vertical axis. The present invention also utilizes a storage table which is mounted underneath the main arm of the robot, so as to be movable along a vertical axis and rotatable about the axis. The present invention further includes an automatic depalletizing mechanism comprising a pivoting arm, of which one of the ends is equipped with a brick-grasping device and the other end is mounted pivotally on a support sliding parallel to the main arm of the robot between two rails of the frame.

  • Patent number: 4784559
    Abstract: Apparatus for lifting successive topmost stacks of large paper sheets and the panels beneath such stacks off a pile of superimposed stacks and panels has one or more separating units each employing a roller which is caused to bear upon the topmost sheet of the topmost stack of the pile and a sword which is aligned with or is disposed at a level slightly below the topmost panel of the pile and is caused to penetrate into the pile so as to lift the topmost stack with the topmost panel preparatory to automatic shifting of the lifted stack and panel sideways into a processing machine. The distance between the lowermost portion of the roller and the plane of the sword is adjustable to permit for subdivision of piles having thicker or thinner stacks. Any sheets which are lifted with a panel and belong to the stack below the lifted panel are stripped off the lifted panel by a continuously driven friction wheel which enters the gap that is formed by the sword.

  • Patent number: RE32794
    Abstract: A programmable automatic assembly system is provided which may be employed to assemble small parts. Each assembly station includes cooperating manipulator arms which are programmable to assemble parts on a centrally located work table. Improved facilities are provided for teaching the manipulator arms at each station, these facilities including a computer which assists the teaching operator in setting up the programs required for assembly of small parts to close tolerances. Each manipulator arm includes closed loop teach facilities for maintaining the arm at a previously located position during the teaching mode of operation. The computer is employed as a teach assist facility in performing a number of tasks during the teaching operation which are extremely difficult for the operator to perform manually. All of the assembly stations may be controlled during playback from a common disc storage facility so that the control circuitry and memory storage facilities at each manipulator are minimized.
