Abstract: The present invention relates to a protection device for protecting a baffle and/or a sprinkler head of a fire sprinkler system, wherein the protection device comprises a mounting portion for mounting to the sprinkler system and a protection portion adapted to at least partially surround the baffle and/or the sprinkler head, so that a damage to the baffle or the sprinkler head by placing stored goods into store or removing them from store can be prevented.

Abstract: An assembly robot has rotational arm and a lifting axis and three rotational axes. A first rotary joint for defining the first rotational axis is mounted in a lateral projection of the lifting column. The assembly makes possible large pivoting angles.

Abstract: A robot joint includes an electric drive motor and step-down transmission ilt into the robot joint housing. The output of the transmission drives a gear to which a mounting flange is coupled. A first part of the robot is coupled to the housing and a second robot part is coupled to the mounting flange. The mounting flange is supported axially and radially in the housing by bearings. The bearings preferably include a conical-roller bearing for providing radial and axial support and a needle bearing for providing axial support. Both bearings are maintained under pretension by a spring, thereby providing a robot joint which is free of play.

Abstract: An industrial robot assembly comprises a support body including a station portion and a vertically translatable portion. A tapered arm member is mounted to the translatable portion of the support for rotation about a first vertically oriented axis, and an angle lever is mounted to the tapered arm member at a point spaced from the first axis for rotation about a second axis parallel to and spaced from the first axis. A first electric motor is operatively connected to the arm member for rotating that member about the first axis, while a second electric motor is operatively connected to the angle lever for rotating that lever about the second axis. A translatable and rotatable component for carrying grippers or another workpiece manipulating element is mounted to the angle lever at a point spaced from the second axis. A third electric motor and a lifting drive are operatively coupled to the holder component for translating the component and for rotating that component about a third axis, respectively.

Abstract: An industrial robot having permanently excited three-phase motors driving each robot joint is described. Each motor is coupled to a common intermediate d-c link through an individual controlled inverter. Electric braking energy of the motors is stored in a large capacitor battery coupled to the intermediate d-c link.

Abstract: A robot joint includes an electric drive motor and step-down transmission ranged in a tubular inner part. The output of the step-down transmission is coupled to a tubular outer part coaxially surrounding the inner part. The outer part is guided on the inner part by bearings. The joint can be disassembled axially after screw connections holding the tubular parts together are loosened.
