Abstract: Apparatus for displacing workpiece carriers from one conveying path to a further conveying path. The apparatus has a lifting device for the workpiece carrier arranged in a transfer zone with which the workpiece carrier can be transferred from the feeding conveyor path to the further conveyor path. The further conveyor path has at least one transport, where pulling run can be lifted and later lowered from the first place to a second place by the lifting device so that the pulling run of the transport belt can serve as a support for the workpiece carrier. Arranged at the end of a transport section of the further conveyor path in the transport zone, is at least one lifting-deflecting device deflecting a transport belt, which lifting-deflecting device can lift and lower the respective transport belt from the first plane to the second plane substantially by the same amount as the lifting device of the same transport belt.

Abstract: An apparatus for shifting work carriers from a main conveying path (40) to a branching conveying path (45) arranged transversely thereto wherein the. The main conveying path (40) consists of a feeding conveying path (41) and a discharging conveying path (42). The conveying paths (40, 41, 42, 45) are formed from double-belt conveyors, one transport belt (45') of the branching conveying path (45) being arranged between the feeding conveying path (41) and the discharging conveying path (42). The feeding conveying path (41) and the discharging conveying path (42) are arranged with their ends in each case above the plane of the transport belt (45') of the branching conveying path (45).

Abstract: A pivotal robot arm is disclosed which includes a support body, at least one pivot arm and a working device that is provided at the outer end of the pivot arm. The pivotal robot arm is characterized in that the support body and/or at least one pivot arm and/or the housing of the working device are each composed of at least one extruded profile that extends in the direction of the articulation axes.

Abstract: A pressure medium linear unit for handling devices for industrial manufacture includes a housing block, at least one operating cylinder for at least one piston, at least one piston rod, at least one guide rod, and guide elements for at least one piston rod and at least one guide rod. The housing block accommodates the at least one operating cylinder for the at least one piston and the guide elements for the at least one piston rod and the at least one guide rod. The housing block is a modular unit and includes a guide unit and a drive unit releasably connected with the guide unit, one behind the other, to form a compact unit in the direction of linear movement. The guide rod and the piston rod are arranged in an axially parallel manner. The end of the guide rod at the end of the drive can be moved within the drive unit. If the guide rod is moved into the drive unit, the drive unit extends at least over the moved-in length of the guide rod.

Abstract: A linear unit for manipulation devices and comprising a housing part having a passage therethrough for receiving a spindle sleeve and a cylindrical bore longitudinally intersecting the passage and for receiving the two bearing elements that support the spindle sleeve for displacement in the passage, the cylindrical bore having a longitudinal axis at least partially lying in a plane in which the longitudinal edge of the spindle sleeve and the longitudinal axis of the spindle sleeve lie, and forming an acute feed angle with the longitudinal axis of the spindle sleeve.

Abstract: Swinging arm robot comprises at least two swinging arms and motor-operated articulated drives. Each motor of the drive is arranged on an articulated part of an articulated axle. At least one swinging arm is not provided with a motor. The motors of the two articulated axles, which are assigned to the one swinging arm, are each fastened at an adjacent articulated part.

Abstract: A linear unit comprises carriage which is arranged longitudinally displaceably in a holder and is driven by a linear motor, the rotor of which is designed as a flexible strip with a tooth structure consisting of magnetic metal. The strip is fixed self-supportingly on the carriage at its two ends and is guided on both sides on the surfaces of the stators of the linear motor bounding the pole gap.

Abstract: A robot arm comprises a robot arm unit, and an assembly flange provided with a unit for centering and fastening of tools, the assembly flange being formed as a wall of a housing member fastened to the robot arm element and having an interior space through which line portions for power supply and control on a robot arm element side can pass, the wall having a plurality of sides and being provided on the sides with openings, a plurality of cover plates arranged to cover the openings, at least one of the cover plates being provided with internal connections for the line portions on the robot arm element side, and also being provided with a unit for connecting the internal connections with further elements.

Abstract: A linear unit for handling equipment of industrial production is proposed, the longitudinally displaceably borne tool support (2 and 19) of which is designed as a gear rack of a linear motor (11 to 18 and 22 to 24) serving for driving the support.

Abstract: Robot joint with an electric drive motor (30), a limit switch (36) for a safety shut off of the same, and a sensor (100) for the zero position-scanning of the joint. The limit switch (36) is actuated by annular segment like platform pieces (50) which are securable in different angle positions on a front face of the one robot part (12). For this purpose, a divided support ring (72,74) is provided which is securable in different angle positions independent from the platform pieces (50) and which has a side face (96,98) which influences the sensor (100).

Abstract: A robot joint has a support carrying a rotary robot arm. An electric drive motor is mounted on the support and its drive shaft is coupled to the robot arm by harmonic drive-type reduction gears. The reduction gears include an elastically deformable, externally toothed ring whose elliptical shape is rotated by the drive shaft. The externally toothed ring itself is stationary and is firmly connected to the support by a flexible sleeve provided at its free end with a rigid mounting flange. The annular mounting face of the flange and the opposite mounting face on the support is each provided with radial teeth, preferably in the form of Hirth-type gears, which guarantee an accurate centering of the sleeve and safeguard the same against turning. Preferably, the flange is fastened to the end face of a steel bushing which is pressed into a bore in the support and secured against turning by knurled serrations.
