Description

Centering device, system and method for operating a centering device Technical Field The invention relates to a centering device for the directional accommodation of cables, comprising a gripping unit consisting of two gripping jaws. The invention also relates to a system comprising a processing station and a centering device. The invention also relates to a method for operating a centering device. Background In order to be able to process the cable end of a cable, in particular a multi-core cable, precisely, the cable end is stripped off the jacket in order to expose the core. For further processing, the core wires are accommodated and held in a centering device, wherein the plurality of core wires are oriented as far as possible in a defined plane. After processing, the centering device is opened so that the cable can be transported further. Such a centering device is already known from the prior art from WO 2016/088088 A1. However, there is the problem that the cable is guided into the centering device in a cable-supply direction (which is usually oriented perpendicular/transverse to the cable longitudinal axis) and is guided out again in a cable-discharge direction opposite to the cable-supply direction. In particular, at least one (upper) gripping jaw blocks the path in order to allow the passage of the cable, i.e. the supply and extraction of the cable in the same direction. This results in the cable transport having to be configured in a complex manner in order to be able to be led out again, which in turn has a disadvantageous effect on the compactness of the centering device. Disclosure of Invention The object of the present invention is therefore to provide a centering device and a system of a processing station and a centering device and a method for operating a centering device, wherein the centering device is designed as compact as possible and at the same time ensures a particularly efficient and simple supply of the cable into and out of the centering device. This object is achieved by a centering device, a system or a method according to the invention. The centering device serves for the directional accommodation of cables, in particular multi-core cables. The centering device has a gripping unit consisting of two gripping jaws, namely a first gripping jaw and a second gripping jaw. For opening and closing the gripping unit, that is to say for actuating the gripping unit, the two gripping jaws can be moved linearly in the gripping actuating direction (respectively). In particular, the two gripping jaws can be moved linearly in opposite directions to one another, that is to say (for closing) toward one another and (for opening) away from one another. The two gripping jaws each have a tool with a tool contour. The tool contours are arranged opposite each other in the gripping direction, i.e. in the gripping direction. In particular, each tool contour can protrude in the direction of the tool contour of the respective other gripping jaw. The tool contour extends in the cable supply direction perpendicular to the gripping direction in order to accommodate at least one, in particular a plurality of, core wires of the cable, in particular in a form-fitting manner. This means that each tool contour, that is to say the respective cross section of the tool contour, is configured to at least partially enclose the respective cross section of the core wire (around the cable longitudinal axis or (single) core wire longitudinal axis). In particular, the tool profile is configured with centering means, by means of which the core wire of the cable can be accommodated. Preferably, the tool profile is configured with a plurality of centering devices, wherein in each centering device the core wire of the cable can be accommodated and preferably all/all core wires of the cable can be accommodated in the plurality of centering devices. The tool profile with the plurality of centering devices is preferably configured to receive the core wires of the cable between the tools for an orientation of the core wire longitudinal axis(s) thereof spaced apart in parallel along the cable supply direction. In other words, the cable longitudinal axis, the gripping direction and the cable supply direction are each oriented perpendicularly to one another. According to one aspect of the invention, the first gripping jaw has a (first) arm. In particular, the arm of the first gripping jaw may extend from the tool (of the first gripping jaw). Preferably, the arms of the first gripping jaw extend substantially in a plane perpendicular to the cable feed direction. The arms have a substantially arcuate trend. The arcuate path is understood to be a U-shape or V-shape formed by two spaced-apart legs, which are connected to one another at the closed end of the arcuate path and are not connected at the open end of the arcuate path. That is, the arm has two legs (oriented substantially parallel or tapering toward each other) that are space
