Abstract: A mounting unit for a tool depositing device includes a coupling carrier having a tool-side coupling element, in particular for a coupling device for a tool of a robot, and a holding device that can be connected to a mounting plate of the tool depositing device. An intermediate space is provided between the holding device and the coupling carrier to allow compensating movements between the coupling carrier and the holding device. The holding device includes two guide rails, between which the coupling carrier is pushed in. An interlocking engagement between the coupling carrier and the guide rails is produced by engaging at least one protuberance in at least one recess, wherein the at least one recess and the at least one protuberance are arranged on mutually opposing sides of the coupling carrier and of the guide rails.

Abstract: The invention relates to a coupling system, a coupling arrangement, a method for mechanically coupling a coupling system and a method for measuring the mechanical loading of a coupling system. The coupling system according to the invention includes a first coupling part, at least one second coupling part, which can be coupled with the first coupling part by way of at least one coupling, and at least one sensor, wherein the first coupling part has an evaluation unit (5), which can be connected to the at least one sensor for sensing measuring signals, and the measuring signals that are sensed by the evaluation unit (5) can be called up by way of the evaluation unit, wherein the coupling in the coupling area can be checked by means of the at least one sensor.
