BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for connecting a coupler servo drive traveling along a guide rail of a textile machine, in particular a twin-twisting machine, to a pressurized air supply nozzle which can wall it on a textile machine and connected to a pressurized air manifold. inside the guide rail. In a device of this kind, the main problem is the stopping of the service trolley of the operator's machine in such a position that its connecting sleeve is precisely in line with the pipe connection port of the compressed air.

The textile machines are mainly driven by a running rail located above the machine. These running rails are statically dimensioned to be able to carry the entire weight of the control unit. At the same time, the power rails are mounted in the running rail, in particular in the form of contact slides, by means of which the operating automaton is supplied with electrical energy necessary for its operation and also for the operation of other elements for machine maintenance and handling and integrated in this service automatu.

However, in many cases, the fastening of the operating automaton only on the upper running support rail is not sufficient and it is necessary to ensure perfect control of the operating automaton by means of a further auxiliary guide and support rail, which is located in the lower part of the machine;

However, automatic controllers for textile machines do not usually have a single source of energy. For example, a pressurized air is needed for handling or for displacing the yarn end. In some cases, the source of the pressurized air may be a compressor which is conveyed together with the operating automaton, but often the constructional conditions do not allow the compressor to be placed directly inside the operating automaton and also to reduce the noise emissions of such auxiliary devices. automatu.

A common way to supply a pressurized air supply to a vending machine is to use a pressurized air supply conduit, which is guided along the machine to be operated, and is typically located in the area of the guide rail.
