Patent number: 5224032Abstract: The present invention pertains to a process and a system for controlling the movements of an axis on program-controlled machines, especially industrial robots, comprising a position control unit and/or a velocity control unit and/or a power control unit. The loads acting on the axis from the outside during the operation are measured by one or several sensors. The load signal is fed back regeneratively in the sense of an increase in the position control variance and sent to the summation point of the position and/or velocity control unit. To increase or decrease the mechanical flexibility of the axis, a controllable amplifying or attenuating device is provided. The sensors may have different designs, corresponding to the loads to be measured. They are preferably directly associated with the axes.Type: GrantFiled: July 6, 1990Date of Patent: June 29, 1993Assignee: Kuka Schwessanlagen+Roboter GmbHInventors: Heinz Worn, Dietmar Schmid

Patent number: 5177319Abstract: An apparatus for loading shells in tubular weapons, particularly tank howitzers, comprises a linearly guided rammer engaging on the bottom of the shell, a pretensioned spring means driving said rammer and a release mechanism acting on the rammer and absorbing the spring tension in the locked position. In order to reliably absorb high ramming forces in a clearance-free manner and so as to suddenly release the same with a limited force requirement, the release mechanism has a fixedly mounted gripper, which cooperates by a planar effective surface with a planar opposite surface on the rammer. The effective surface and the opposite surface are in each case one face of a freely rotatably mounted polyhedron and, in the locked position, are at an angle less than 90.degree. to the force vector of the spring means. For releasing the rammer, the gripper can be pivoted by a release drive acting at right angles to the force vector.Type: GrantFiled: June 28, 1991Date of Patent: January 5, 1993Assignee: Kuka Wehrtechnik GmbHInventor: Wolfgang Grimm
