Patent number: 10786908Abstract: An adapter which allows an object to be pulled into a chamber after being gripped by a gripper module with a drive, said chamber being formed by an outer shell is provided. The outer shell is designed to at least partly cover the object and is sufficiently large so as to shield the object. The adapter can be understood as a gripper base system to which the gripper module is adapted. The drive pulls the entire gripper module including the object into the gripper base system. The adapter provides a safety gripper system with an object housing for a safe human/robot interaction. The outer shell protects persons from sharp-edged objects which are gripped by the gripper module and which could otherwise lead to an injury of the persons located in the working area.Type: GrantFiled: July 29, 2016Date of Patent: September 29, 2020Assignee: Siemens AktiengesellschaftInventor: Detlef Gerhard

Patent number: 10171009Abstract: A device and a method for moving an object in a vertical direction are disclosed. The device includes a plurality of piezo-actuators expanding in directions upon activation and in doing so generating pressure forces on an active side, and a hydraulic transmission device that converts the pressure forces of the piezo-actuators into a vertical pressure force for moving the object opposite the direction of gravity and transmits the pressure force with a transmission ratio. The object is lifted after the vertical pressure force has exceeded an oppositely acting spring force of a spring system.Type: GrantFiled: May 21, 2014Date of Patent: January 1, 2019Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Detlef Gerhard, Martin Renner

Patent number: 9255303Abstract: In a method for determining a state variable of an electric arc furnace, especially for determining the level of the foamed slag (15) in a furnace, the energy supplied to the furnace is determined with the aid of at least one electric sensor while solid-borne noise is measured in the form of oscillations on the furnace. The state variable is determined by a transfer function which is determined by evaluating the measured oscillations and evaluating measured data of the electric sensor. The state of the foamed slag level can thus be reliably recognized and be monitored over time. The foamed slag level is decisive for the effectiveness with which energy is fed into the furnace. Furthermore, losses caused by radiation are reduced by covering the arc with the foamed slag. The improved measuring method allows the foamed slag level to be automatically controlled or regulated in a reliable manner.Type: GrantFiled: August 24, 2010Date of Patent: February 9, 2016Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Dieter Fink, Detlef Gerhard, Thomas Matschullat, Detlef Rieger, Reinhard Sesselmann

Publication number: 20140233040Abstract: A focal point generated by a confocal sensor system is moved along a visual axis, orthogonal to the x, y-plane of an x, y, z-coordinate system, to a target z-coordinate of a point to be measured on a surface of an object. A light intensity of light reflected by the surface is dependent on a distance of the focal point along the z-axis to the point to be measured, and is detected and used in determining the actual z-coordinate of the point to be measured by an evaluation device.Type: ApplicationFiled: September 3, 2012Publication date: August 21, 2014Inventors: Werner Gergen, Detlef Gerhard, Martin Weber

Patent number: 7434856Abstract: The invention relates to a gripper for handling frames (2) that are covered with a film (3) that is intended for the transport of wafers (6). The gripper comprises at least two flat fingers (10) that carry flattened finger tips (8). This construction allows to insert the gripper between two frames (2) that are mounted in a cassette (9) without complication. The fingers (10) support in subsections both the frame (2) and the film (3). The film is attached to the frame due to the suction effect exerted by vacuum openings (5) configured on the frame, thereby fixating the film on the gripper.Type: GrantFiled: December 4, 2003Date of Patent: October 14, 2008Assignee: ICOS Vision Systems N.V.Inventors: Detlef Gerhard, Johannes Lechner, Martin Renner
