Abstract: An arm engageable with a mounting receiver of an automated tooling system. The arm comprises a wall defining a central bore extending the length of the arm, and at least pin engageable with the mounting receiver to engage the mounting receiver for aligning and receiving the mounting receiver. The pin may be a plasma ion nitrided pin. The arm may also include first and second ends, an electrical power supply connector positioned inside the bore adjacent the first end and wiring. The second end defines an opening. The wiring is connected to the electrical power supply connector, and extends unexposed within the bore from the electrical power supply connector through the opening to supply power to the gripper.

Abstract: A vacuum generator which operates on the ejector principle. A multi-stage ejector has a plurality of nozzles arranged in a row. An air stream, an air from a compressed air connection flows through these nozzles at high speed to an outlet so that a negative pressure is generated in a valve chamber which surrounds the nozzles. A shut off valve closes the air outlet in an air tight fashion. The valve chamber or an evacuation chamber in which the negative pressure is generated has a conduit which is closed by an aeration valve which cooperates with the shut off valve, by which an aeration conduit for aerated the chambers in which the negative pressure is generatable is opened.

Abstract: A method and an apparatus serve to secure a gripper tool detachably to a movable crossbar of a transfer press. The gripper tool has two saddles, with spacing between them, which are brought into engagement with two bearings mounted on the crossbar and locked in a defined engagement position. To attain faster, simpler assembly, the gripper tool is introduced in an inclined position relative to the crossbar, by at least one protrusion of rounded longitudinal section or tapering in wedgelike fashion, on the first saddle, into a correspondingly rounded or V-shaped narrowing recess in the first bearing. The second saddle is then pivoted toward the crossbar. In the process, wedge faces on the second saddle and on the second bearing press the protrusion axially against the wall of the recess by the force of gravity. In the end position, the second saddle is locked to the second bearing.

Abstract: The invention is used to connect round or octagonal tubes conducted past each other in an intersecting manner by means of at least one screw, in particular in connection with support frames equipped with vacuum grippers for transporting and holding sheet metal parts in the automobile industry. In each one of the two tubes an insert is arranged at the joint, which matches their respective inner cross section and partially fills it, one of the inserts constitutes an underlay for the head of the screw extending through aligned transverse bores in the tubes, and whose other insert forms a support for the screw shank. An intermediate element matched to the outer circumferential surfaces of the two tubes is clamped between the two tubes.

Abstract: The method and the apparatus serve to secure a gripper tool (12) detachably to a movable crossbar of a transfer press. The gripper tool has two saddles (14, 16), with spacing between them, which are brought into engagement with two bearings (24, 26) mounted on the crossbar and locked in a defined engagement position. To attain faster, simpler assembly, the gripper tool (12) is introduced in an inclined position relative to the crossbar, by at least one protrusion (42) of rounded longitudinal section or tapering in wedgelike fashion, on the first saddle (14), into a correspondingly rounded or V-shaped narrowing recess (40) in the first bearing (24). The second saddle (16) is then pivoted toward the crossbar. In the process, wedge faces (44?, 52?) on the second saddle and on the second bearing (26) press the protrusion (42) axially against the wall of the recess (40) by the force of gravity. In the end position, the second saddle (16) is locked to the second bearing (26).

Abstract: The motor-actuable coupler is used for connecting workpiece grippers with a manipulating device, in particular a robot, which passes on workpieces from one stamping press to the next. The coupler consists of a fixed element (12, 66, 80, 38) on the drive side and a connecting element (10, 54) on the gripper side. Since normally a very large number of different workpiece grippers are employed and the connecting elements on the gripper side entail great costs, it is proposed that the fixed element of the coupler has a collet chuck (66, 74, 80, 38), and that the connecting element (10, 54) is a tube section, which can be centered in the fixed element (12, 66, 80) spaced apart from the clamping area (at 68, 76) located at the front end of the collet chuck. The tube section (10) is preferably centered by clamping faces (70, 78) and/or by cone surfaces (58) at its end which can be inserted into the collet chuck (14).

Abstract: A transporter or transport robot especially for transporting workpieces between presses has a cantilever arm swingable about a vertical first axis on a stationary base and a horizontal second axis in a common plane. A linear positioner is swingable at a free end of this cantilever arm about a vertical third axis and carries a gripper head on which the gripper is mounted for rotation about further axes. The workpiece can thus be swung across the first vertical axis to maintain its position along a line between the presses if the linear positioner and cantilever arm will swing in opposite senses. The actuator for the angular displacement may be electrical or hydraulic and a linear motor can be provided for the linear positioner.

Abstract: The conveyor robot which, in particular, is intended for being mounted between presses, comprises a double arm (14) that is rotatable about a central, vertical axis (12) and swingable about a central, horizontal axis (16). Both ends of the double arm (14) support engaging members (26) which, independently of one another, are extendable to opposite sides. The double arm (14) is formed with an articulated joint the axis of which coincides with the central, horizontal axis (16). The two parts (36,38) of the double arm (14) separated by the articulated joint are interconnected by a cross-bar (28) variably adjustable in length.

Abstract: A conveyor robot with a double arm with engaging members at both ends which are rotatable about a vertical axis and in a particular case additionally swingable about a horizontal axis. Both engaging members can be simultaneously moved in the longitudinal direction of the arm, in opposite directions. Both engaging members can have a common drive for their movements of rotation and another common drive for their swinging movements.
