SPINNING MEANS FOR A WORK STATION OF A TEXTILE MACHINE, AND TEXTILE MACHINE AND METHOD FOR OPERATING A TEXTILE MACHINE HAVING A PLURALITY OF WORK STATIONS

Abstract

The invention relates to a spinning means for a work station of a textile machine having a plurality of work stations, comprising a first spinning means identification for identifying and/or authenticating the spinning means at a work station. Furthermore, the invention relates to a textile machine having a plurality of work stations and a method for operating the same, wherein the work stations have replaceable spinning means, each having a first spinning means identification. In order to provide a spinning means that has a particularly forgery-proof spinning means identification, it is provided that the first spinning means identification is formed by at least one specific, sensor-detectable material property of a spinning means material and/or a coating applied to the spinning means material. In order to provide a method for operating a textile machine which prevents operation with unsuitable spinning means, it is provided that the first spinning means identification formed by a material property of the spinning means is monitored by a sensor device and, depending on the detected material property, operation of the respective work station is blocked or limited.

Description

[0035] FIG. 1 shows a first embodiment of a spinning means designed as a spinning rotor, with a first embodiment of a second spinning means identification arranged on a rotor cup, and

[0036] FIG. 2 shows a second embodiment of a spinning rotor, with a second embodiment of a second spinning means identification arranged on the rotor cup.

[0037] FIG. 1 shows, by way of example, a spinning rotor 1 as a replaceable spinning means of a work station (not shown here) of a textile machine. On an outer side 2 of a rotor cup 3, the spinning rotor 1 has a second spinning means identification designed as a bar code 4 which is etched into the outer side, for example, or has been applied by means of a laser. In an alternative not shown here, instead of the shown bar code 4, a QR code can also be used to form a second spinning means identification.

[0038] FIG. 2 shows a second embodiment of a spinning rotor 1 which has a passive transponder in the form of an RFID chip 5 on the outer side 2 of the rotor cup 3. The RFID chip 5 is used not only for identification, but can also contain spinning rotor-specific information which can be processed in a control device of the textile machine (not shown here). Alternatively, instead of the passive transponder, an active transponder (not shown here) can also be used, i.e., a transponder which has its own power supply device, which increases the range within which data can be received and transmitted by the transponder.

[0039] According to a further particularly preferred embodiment (not shown) the code or the transponder is arranged on the rotor bottom, in particular on the end face of the axis of the spinning rotor 1.

[0040] According to a further embodiment of the present invention, the rotor cup 3 has a coating. The coating extends over the inner region of the rotor cup 3. That is, the coating is applied to the rotor groove, the fiber slip surface, and the base surface. Furthermore, the coating extends onto the outer side 2 of the rotor cup 3. The coating is admixed with solid particles.

[0041] A sensor device detects the concentration of the solid particles in the coating. According to the present example, the concentration is 0.9%. For example, it is stored in the control device of the textile machine that spinning rotors of type A have a concentration of the solid particles between 0.1% and 0.5%. Spinning rotors of type B have a solid particle concentration of 0.51% to 1.0%. In the present example, a spinning rotor of type B can thus be detected on the basis of the measured concentration of 0.9%.

[0042] During the spinning operation, the inner region of the rotor cup 3 is constantly in contact with fibers and is thus subject to wear. In contrast, the outer side 2 is largely wear-free. A wear evaluation can take place by comparing the concentration of the solid particles in the wear zone and in the non-wear zone.
