Abstract:
A safety control system (1), including a control unit (3), safety sensor (4) and machine (5) arrangements, operable in different operation modes (F 0 ,F N , F 1 , F 2 ), each having a different productivity (P 0 , P N , P 1 , P 2 ) of the machine arrangement (5), whereby the control unit (3) activates a operation mode (F 0 ,F N , F 1 , F 2 ) of the machine arrangement (5), wherein the at least one safety sensor arrangement (4) has two functionally redundant subsystems (6, 7), input to the control unit (3) includes information (8) indicating availability of said subsystems (6, 7), the control logic (3) may activate a normal operation mode (F N ) with normal productivity (P N ) if all subsystems (6, 7) are available, activate a fail-stop mode (F 0 ) of operation with zero productivity (P o ) upon unavailability of all subsystems (6, 7), activate a fail-operate mode (F 1 , F 2 ) of operation with non-zero productivity less than normal upon unavailability of at least one and availability of at least another subsystem (6, 7).
Abstract:
The invention is related to a control system (18, 62) for at least one robot (16, 68), comprising a data processing means (66) and a robot program stored thereon, whereas the robot program determines at least one trajectory of the at least one robot (16, 68) by a given movement path and a given movement speed. The control system (18, 62) is configured to receive and process safety-relevant first information (46, 84) of a person (12) near or within the working range of the at least one robot (16, 68). The processed first information (88) causes either an emergency or protective stop of the at least one robot (16, 68) or no reaction during the execution of the robot program. The control system (18, 62) is configured to alternatively receive and process safety-relevant second information (42, 76, 78, 80, 82, 83) of a person (12) near or within the working range of the robot (16, 68), whereas the processed second information (86) adaptively influences the trajectory of the at least one robot (16, 68), so that the safety of the person (12) is ensured while executing the robot program. The invention is also related to a belonging method for control.
Abstract:
The invention refers to a system and a method for safety protection of human beings against hazardous incidents with robots in operation by means of a monitoring means comprising sensor means which are able to receive and measure signals caused by the respective human being who might be in a dangerous situation within or near the working range of the robot, where the acoustical and/or optical sensors are located close around the robot within or near its working range, where said monitoring means comprises a processing means being linked to the acoustical and/or optical sensors, and where said processing means evaluates the received signals as for the source in order to trigger the robot controller to execute a control action leading to a safe situation.
Abstract:
The invention is related to a safe robot system, comprising at least one robot (16, 62), comprising at least one sensor means (22, 26, 30) for the measurement of data of at least one person (12, 66, 82), which is within or near the working range of the at least one robot (16, 62) and comprising a processing system (20) for the measured data. At least one person-related parameter is determined by the processing system (20) and a predetermined trajectory of the at least one robot (16, 62) is adaptively influenced by the at least one person-related parameter.
Abstract:
Die Erfindung betrifft ein Verfahren zum Verbinden von Formteilen, wobei wenigstens ein erstes Formteil in einem ersten Haltevorrichtungsteil (10) gehalten ist und wobei wenigstens ein zweites Formteil in wenigstens einem zweiten Haltevorrichtungsteil (30) gehalten ist. Die Haltevorrichtungsteile (10, 30, 72, 74, 92, 94) werden in einem ersten Handhabungsschritt in eine Relativposition zueinander mit einer gemeinsamen Kontaktfläche bewegt. In einem zweiten Handhabungsschritt werden bei unveränderter Relativposition das wenigstens erste Formteil und das wenigstens zweite Formteil mittels wenigstens einer relativ zu einem der Haltevorrichtungsteile (10, 30, 72, 74, 92, 94) bewegbaren Bewegungsvorrichtung (40) zueinander bewegt, bis eine durch Form- und/oder Kraftschluss hergestellte Verbindungsposition der jeweiligen Formteile zueinander mit gemeinsamer Kontaktfläche erreicht wird. Die Erfindung betrifft fernerhin eine diesbezügliche Verbindevorrichtung.
