Description

Arrangement for transporting wires from an automatic wire assembly machine to a pick-up point Technical Field The present invention relates to an arrangement for transporting wires from an automatic wire assembling machine to a pick-up point for manual, semi-automatic or fully automatic wiring in a switching and control device. This arrangement can be used in particular if all process steps are to be carried out in situ and preferably substantially simultaneously in order to achieve as high a longitudinal integration as possible of the wiring from the assembly of the electrical lines up to the switching and/or control device. Background In the manufacture of switches and control devices, the wiring process is one of the most core and time-consuming work steps, which, to date, has often been performed entirely manually. Not only is the high complexity of the working process, but the requirement of being completely error-free also places high demands on the staff engaged in the assembly of the switch and control device. To optimize this wiring process, different technical aids with different support levels are known. This includes hand tools and/or semi-automatic machines for wire assembly, up to fully automated equipment that completely pre-assembles individual wires, such as cuts, peels, applies and crimps the core wire end sleeve, for subsequent use as loose individual wires, wire chains of serially connected, pre-assembled individual wires, or in the form of coil boxes on which individual wires are serially arranged. However, as an interface for receiving and processing pre-assembled wires with a robot for an automated wiring process, there is currently no known technical solution. In particular, it has proven to be particularly complex for the robotic handling of individual pre-assembled wires provided as wire bundles or wire combination sequences for handling by the robot, in particular because the wires are flexible components. Disclosure of Invention The object of the present invention is therefore to provide an arrangement of the type described at the outset which allows preassembled wires to be received and processed by the pick-up point in order to be routed for the switch or control device semi-automatically or fully automatically. The object is achieved by an arrangement having the features of claim 1. The dependent claims relate to various advantageous embodiments of the invention, respectively. The arrangement according to the invention has an automatic wire assembly machine and a pneumatic conveying system, wherein a wire adapter between the automatic wire assembly machine and the pneumatic conveying system has a wire inlet arranged in an entry region of the automatic wire assembly machine and also has a wire outlet which opens into at least one transport wire of the pneumatic conveying system, wherein the at least one transport wire is guided between the wire adapter and the pick-up point. The arrangement according to the invention allows the individual wires to be routed, pre-assembled, to be manufactured by means of an automated assembly machine immediately before routing and to be transported as individual wires via an air pressure transport system to a pick-up point (e.g. an articulated arm robot), without using a pre-assembled wire harness consisting of a plurality of pre-assembled individual wires, which wire harness has to be separated again separately for automated routing, so that it is no longer necessary to separate the wire harness separately or the wire combination sequence separately or to distinguish the individual wires of the wire harness or wire combination sequence in some cases. The preassembled wires, which usually belong to a flexible assembly, are purposefully fed to the pick-up point based on the threading of the preassembled wires through the transport wire. It is then ensured that the wire reaches the pick-up point first with its core wire end treatment (e.g. core wire end sleeve), for example the end effector of an articulated arm robot, so that the robot can reliably attach the wire flow to the core wire end treatment, for example the core wire end sleeve. If the pick-up point has an articulated arm robot, it can be designed to let the conveyor line pass directly into the end effector of the articulated arm robot. The articulated arm robot may have a wire threading brake, known in the art, consisting of two counter-rotating and gapped rollers, belts or tracks, by means of which a single wire fed to the end effector can be fed to the gripper of the end effector with a defined feed amount, at a feed speed, for example, resulting from the rotational speed of the rollers, belts or tracks. Instead of a separate wire threading brake, a roller pair, belt pair or crawler pair may be provided that has been provided at the end effector for transporting the wire originally, to brake the wire approaching via the transporting wire to a prescribed feeding speed.
