Aus der DE OS 37 32 367 ist ein Verfahren zum Vorbereiten eines nachfolgenden Be- oder Verarbeitungsvorganges einer Textilspule bekannt, wobei an der Textilspule oder an deren Hülse ein les- und beschreibbarer elektronischer Speicherchip angeordnet wird. Der Speicherchip dient der Hinterlegung von spezifischen Angaben für die jeweilige, an einer Textilmaschine hergestellte Textilspule, wie das Herstellungsdatum, die Herstellungsuhrzeit, der Herstellungsort, die Maschinennummer, die Partienummer, das Fasermaterial, die Garnlänge und dergleichen. Es werden aber auch Angaben über die Anzahl erfolgter Reinigerschnitte oder die Anzahl der behobenen Garnbrüche, die während der Herstellung der Textilspule aufgetreten sind, die für nachgelagerte Be- oder Verarbeitungsvorgänge relevant sind, erfasst.From the DE OS 37 32 367 a method for preparing a subsequent loading or processing operation of a textile bobbin is known, wherein a readable and writable electronic memory chip is arranged on the textile bobbin or on its sleeve. The memory chip serves to deposit specific information for the particular textile spool produced on a textile machine, such as the date of manufacture, the time of manufacture, the place of manufacture, the machine number, the lot number, the fiber material, the yarn length and the like. However, information is also reported on the number of cleaner cuts made or the number of yarn breaks that have occurred during the production of the textile bobbin, which are relevant for downstream processing or processing operations.

Aus der DE 197 55 060 A1 ist ein Verfahren zum Betreiben einer Offenend-Spinnvorrichtung bekannt, bei der an einem Spinnrotor eine Identifikationsmarkierung angeordnet wird, die als Transponder oder als Strichcode ausgebildet ist. Der Transponder wie auch der Strichcode dienen als Informationsträger von für den Spinnrotor spezifischen Produktdaten, wie Baujahr, Typ, Größe oder dergleichen. Diese auslesbaren Informationen werden dazu verwendet, die fehlerhafte Verwendung eines Spinnrotortyps beim Einbau des Spinnrotors in eine Arbeitsstelle einer Offenend-Spinnvorrichtung zu vermeiden. Dies dient dazu, dass sichergestellt wird, dass stets die für die jeweilige Garnpartie spinntechnologisch richtigen Spinnrotoren zum Einsatz kommen. Der verwendete Transponder ist mit einer fest eingespeicherten Codierung versehen, die nur die Spezifikation des Spinnrotors ermöglicht.From the DE 197 55 060 A1 a method for operating an open-end spinning device is known in which an identification mark is arranged on a spinning rotor, which is designed as a transponder or as a bar code. The transponder as well as the bar code serve as information carriers of product data specific to the spinning rotor, such as year of manufacture, type, size or the like. This readable information is used to avoid the erroneous use of a spinning rotor type when installing the spinning rotor in a workstation of an open-end spinning device. This serves to ensure that always for the respective yarn section Spinnrotoren right spin spinning rotors are used. The transponder used is provided with a permanently stored coding, which allows only the specification of the spinning rotor.

Das gemäß der DE 197 55 060 A1 vorgeschlagene Verfahren sieht lediglich die Identifikation des verwendeten Spinnrotors vor dem Hintergrund sicherheitstechnischer und produktionstechnischer Aspekte vor.That according to the DE 197 55 060 A1 proposed method provides only the identification of the spinning rotor used against the background of safety and production aspects.

Aus der DE 101 17 095 A1 ist es bekannt, austauschbare Maschinenkomponenten einer Textilmaschine mit einer Identifikationskennzeichnung zu versehen. Die Identifikationskennzeichnungen sind als Farbmarkierungen ausgebildet, die mittels eines optischen Erfassungssystemes ausgelesen werden. Die ausgelesenen Informationen lassen in bereits genannter Weise einen Rückschluss auf die Art und den Typ der austauschbaren Komponente zu. Auf diese Weise soll der spinntechnologisch sinnvolle Einsatz der Komponenten an der Textilmaschine sichergestellt werden, wie bereits aus der DE 197 55 060 A1 bekannt. Auch die DE 101 17 095 A1 offenbart lediglich die Möglichkeit der Identifikation einer austauschbaren Komponente vor dem Hintergrund sicherheitstechnischer und produktionstechnischer Aspekte.From the DE 101 17 095 A1 It is known to provide replaceable machine components of a textile machine with an identification tag. The identification markings are designed as color markings, which are read out by means of an optical detection system. The information read out in the manner already mentioned permits a conclusion about the type and type of replaceable component. In this way, the purpose of the spinntechnologisch meaningful use of the components is to ensure the textile machine, as already from the DE 197 55 060 A1 known. Also the DE 101 17 095 A1 discloses only the possibility of identifying a replaceable component against the background of safety and production aspects.

Somit liegt der vorliegenden Erfindung die Aufgabe zugrunde, ein Verfahren sowie eine Textilmaschine zur Durchführung des Verfahrens bereitzustellen, wodurch die automatische Erfassung von den Verschleiß einer austauschbaren Komponente beeinflussenden Daten ermöglicht wird.Thus, the present invention has for its object to provide a method and a textile machine for performing the method, whereby the automatic detection of the wear of a replaceable component influencing data is made possible.

Diese Aufgabe wird hinsichtlich des Verfahrens durch die kennzeichnenden Merkmale des Anspruches 1 und bezüglich der Textilmaschine durch die kennzeichnenden Merkmale des Anspruches 9 gelöst.This object is in terms of the method by the characterizing features of claim 1 and with respect to Textile machine solved by the characterizing features of claim 9.

Weiter vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.Further advantageous embodiments are the subject of the dependent claims.

Gemäß Anspruch 1 wird vorgeschlagen, dass während des Lebenszyklus' der austauschbaren Komponenten zumindest die für diese während ihrer Einsatzzeit erfassbaren Betriebsdaten, die den Verschleißzustand der austauschbaren Komponenten unmittelbar beeinflussen, auf dem Transponder gespeichert werden. Bei den zu erfassenden Betriebsdaten handelt es sich beispielsweise um Daten, wie die mit den jeweiligen Komponenten verarbeitete Tonnage, gegebenenfalls aufgeschlüsselt auf mehrere Partien und die Zahl der Betriebsstunden, in denen die Komponenten im Einsatz waren. Ebenso können die Einsatzbedingungen erfasst werden, unter denen die austauschbaren Komponenten eingesetzt wurden, wie beispielsweise die Drehzahl während der Verarbeitung einer-Partie, die durchschnittliche Drehzahl über die Einsatzdauer oder die Gesamteinsatzdauer der Komponenten. Aber auch die Anzahl der Fadenbrüche oder der Reinigerschnitte bezogen auf die Einsatzdauer der Komponenten können in dem jeweiligen Transponder erfasst werden.According to claim 1, it is proposed that during the life cycle of the exchangeable components, at least the operating data which can be detected for them during their operating time and which directly influence the state of wear of the exchangeable components be stored on the transponder. The operating data to be collected are, for example, data such as the tonnage processed with the respective components, possibly broken down to several lots, and the number of operating hours in which the components were in use. Likewise, the conditions under which the interchangeable components were used, such as the number of revolutions during the processing of a batch, the average speed over the period of use or the total duration of use of the components, can be recorded. But also the number of thread breaks or cleaner cuts based on the duration of use of the components can be detected in the respective transponder.

Die über die Lebensdauer erfassten Betriebsdaten erlauben die Beurteilung des verschleißgradabhängigen Verhaltens der austauschbaren Komponenten unter unterschiedlichen Einsatzbedingungen. Auf diese Weise lassen sich für die jeweiligen Komponenten Qualitätsprofile erstellen, was eine Optimierung der austauschbaren Komponenten bezogen auf ihre Einsatzbedingungen ermöglicht. Dies kann zu einer verbesserten Ausnutzung der Standzeiten führen, wobei zur Verarbeitung einer Partie Komponenten gleichen Typs mit ähnlichem Verschleißzustand eingesetzt werden.Operational data collected over the service life allows assessment of the wear-level-dependent behavior of the interchangeable components under different operating conditions. In this way, quality profiles can be created for the respective components, which enables an optimization of the exchangeable components in relation to their conditions of use. This can lead to an improved utilization of the service life, whereby components of the same type with a similar state of wear are used for processing a batch.

Hierzu kann beim Austausch von Komponenten die Qualität der zum Austausch verwendeten Komponente anhand der Betriebsdaten schnell überprüft und verglichen werden, wodurch eine verlässlichere Aussage über deren Einsatzfähigkeit vorgenommen werden kann. Darüber hinaus wird eine Kategorisierung der Komponenten in Abhängigkeit vom Verschleiß ermöglicht, wodurch die Lagerhaltung transparenter wird. Mögliche Kategorien sind vor allem die tatsächliche Einsatzdauer der Komponenten beziehungsweise der erzielte Durchsatz.For this, when replacing components, the quality of the component used for replacement can be quickly checked and compared on the basis of the operating data, which makes it possible to make a more reliable statement about its usability. In addition, a categorization of the components depending on the wear is made possible, making the storage more transparent. Possible categories are above all the actual duration of use of the components or the achieved throughput.

Außerdem lässt sich auf Grund der Kenntnis des Verschleißes der eingelagerten Komponenten abwägen, ob und in welchem Umfang die betreffenden Komponenten erneut zum Einsatz kommen beziehungsweise welche Qualität bei der Verarbeitung einer Partie auf Grund der Verwendung der Komponenten an einer Textilmaschine erreichbar ist.In addition, based on the knowledge of the wear of the stored components can be weighed whether and to what extent the components concerned are used again or what quality can be achieved in the processing of a lot due to the use of components on a textile machine.

Vorrangig sollen die Betriebsdaten der austauschbaren Komponenten erfasst werden, die unmittelbar mit dem zu verarbeitenden Material, wie dem Faserband oder dem herzustellenden Faden, in Verbindung kommen. Erfindungsgemäß findet das Verfahren bei verschiedenen Textilmaschinen, wie Rotorspinnmaschinen, Ringspinnmaschinen, Spulmaschinen, Zwirnmaschinen oder dergleichen Anwendung, bei denen insbesondere die austauschbaren Komponenten mit Transpondern versehen werden, die unmittelbar mit dem zu verarbeitenden Material in Berührung kommen und somit einem stärkeren Verschleiß ausgesetzt sind, als beispielsweise andere austauschbare Komponenten der Textilmaschinen.It is primarily intended to record the operating data of the exchangeable components, which come in direct contact with the material to be processed, such as the sliver or the thread to be produced. According to the invention, the method is used in various textile machines, such as rotor spinning machines, ring spinning machines, winders, twisting machines or the like application, in which in particular the interchangeable components are provided with transponders, which come directly into contact with the material to be processed and are thus exposed to greater wear than for example, other interchangeable components of textile machines.

Ein weiterer wesentlicher Vorteil ergibt sich dadurch, dass die in dem Transponder erfassten Betriebsdaten beim Entfernen der austauschbaren Komponenten aus der Textilmaschine nicht gelöscht werden. Die in den Transpondern erfassten Betriebsdaten stehen auch für einen wiederholten Einsatz der austauschbaren Komponenten zur Verfügung, da die Betriebsdaten individuell in dem der jeweiligen Komponente zugehörigen Transponder gespeichert wurden und nicht an einer zentralen Stelle der Textilmaschine. Auf diese Weise wird der erforderliche Speicherbedarf an der Textilmaschine reduziert. Zudem müssen die Textilmaschinen hierfür nicht derart miteinander verbunden sein, dass sie untereinander Betriebsdaten austauschen können, um zu gewährleisten, dass bei der Verwendung der Komponente an einer anderen Textilmaschine gleichen Typs die Historie des Lebenszyklus' der ausgetauschten Komponente bereit steht. Vielmehr sind die in den Transpondern erfassten Betriebsdaten der Komponenten jederzeit abrufbar und können zur Beurteilung des Verschleißzustandes herangezogen werden.Another significant advantage results from the fact that the operating data recorded in the transponder are not deleted when removing the replaceable components from the textile machine. The operating data recorded in the transponders are available also for a repeated use of interchangeable components, since the operating data were stored individually in the respective component associated transponder and not at a central point of the textile machine. In this way, the required storage space is reduced on the textile machine. In addition, the textile machines do not need to be interconnected in such a way that they can exchange operational data with each other to ensure that when the component is used on another textile machine of the same type, the history of the life cycle of the replaced component is ready. Rather, the operating data of the components recorded in the transponders are retrievable at any time and can be used to assess the state of wear.

Insbesondere können die für die austauschbare Komponente relevanten Betriebsdaten bei einer Arbeitsunterbrechung zur Erfassung automatisch auf den Transponder übertragen werden. Dies kann beispielsweise bei der Einleitung eines Spulenwechsels oder eines Partiewechsels beziehungsweise bei einem Fadenbruch oder einem Reinigerschnitt sowie nach dem Einschalten der Textilmaschine der Fall sein. Somit wird eine lückenlose Erfassung der Betriebsdaten über den Lebenszyklus der austauschbaren Komponenten erreicht.In particular, the operating data relevant to the replaceable component can be automatically transferred to the transponder during a work interruption for detection. This can be the case, for example, in the introduction of a bobbin change or a lot change or in a thread break or a cleaner cut and after switching on the textile machine. Thus, a complete acquisition of the operating data over the life cycle of the exchangeable components is achieved.

Vorteilhafterweise können die im Transponder hinterlegten Betriebsdaten beim Einbringen der Komponenten in die Arbeitsstellen der Textilmaschine automatisch ausgelesen werden. Somit stehen dem Bedienpersonal die Daten der jeweiligen Komponenten, die im Austausch gegen andere Komponenten in die Textilmaschine eingebaut werden, zur Verfügung. Die Anzeige der Daten kann hierzu beispielsweise unmittelbar an der jeweiligen Arbeitsstelle oder an einer zentralen Steuereinheit erfolgen.Advantageously, the operating data stored in the transponder can be read out automatically when the components are introduced into the workstations of the textile machine. Thus, the operators of the data of the respective components, which are installed in exchange for other components in the textile machine available. For this purpose, the data can be displayed, for example, directly at the respective workstation or at a central control unit.

Alternativ können die in den Transpondern der austauschbaren Komponenten hinterlegten Betriebsdaten unabhängig von deren Einsatz in den Arbeitsstellen der Textilmaschine ausgelesen werden. Dies ist insbesondere bei der Lagerung der austauschbaren Komponenten von Vorteil, da die in den Transpondern erfassten Betriebsdaten jederzeit abrufbar sind, um die Komponenten entsprechend ihres Verschleißzustandes zu kategorisieren beziehungsweise um diese bereits vor deren Einbau in die Arbeitsstelle der Textilmaschine selektieren zu können.Alternatively, the operating data stored in the transponders of the exchangeable components can be read out independently of their use in the workstations of the textile machine. This is particularly advantageous when storing the exchangeable components, since the operating data recorded in the transponders can be called up at any time in order to categorize the components according to their state of wear or to be able to select them before they are installed in the workstation of the textile machine.

Dazu kann der Transponder mittels einer Sende-Empfängseinrichtung ausgelesen und beschrieben werden. Weiterhin können die in dem Transponder hinterlegten Betriebsdaten verschlüsselt werden. Auf diese Weise lässt sich das ungewollte Auslesen oder Überschreiben der in den Transpondern hinterlegten Betriebsdaten unterbinden.For this purpose, the transponder can be read out and written by means of a transceiver device. Furthermore, the stored in the transponder operating data can be encrypted. In this way, the unwanted reading or overwriting of stored in the transponders operating data can be prevented.

Gemäß den kennzeichnenden Merkmalen des Anspruches 9 wird unter anderem vorgeschlagen, dass im Bereich jeder Arbeitsstelle eine Sensoreinrichtung zum Beschreiben und Auslesen der an den Komponenten angebrachten oder in die Komponenten integrierten Transponder angeordnet ist. Auf diese Weise werden die bereits auf dem Transponder erfassten Betriebsdaten bei Einbringung der Komponenten in die jeweilige Arbeitsstelle der Textilmaschine ausgelesen beziehungsweise werden die Betriebsdaten in bereits eingebauter Position der Komponenten nach jedem abgeschlossenen Arbeitsgang aktualisiert, um den Lebenszyklus der Komponenten fortlaufend zu dokumentieren. Bei einer erstmaligen Inbetriebnahme der Komponenten werden diese initialisiert, das heißt, es wird der Inbetriebnahmezeitpunkt auf dem Transponder der Komponenten abgespeichert.According to the characterizing features of claim 9, it is proposed, inter alia, that in the region of each workstation a sensor device is arranged for writing and reading out the transponders attached to the components or integrated in the components. In this way, the operating data already recorded on the transponder are read out when the components are brought into the respective workstation of the textile machine or the operating data are updated in already installed position of the components after each completed operation in order to continuously document the life cycle of the components. When commissioning the components for the first time, these are initialized, that is, the commissioning time is stored on the transponder of the components.

Gemäß dem kennzeichnenden Teil des Anspruchs 9 weisen die Arbeitsstellen jeweils eine Steuereinrichtung auf, die mit den Sende-Empfangseinrichtungen in Verbindung stehen. Weiterhin kann die Textilmaschine eine zentrale Steuereinheit aufweisen, die mit den Sende-Empfangseinrichtungen in Verbindung steht. Somit erfolgt die Übertragung der Betriebsdaten durch die übergeordnete zentrale Steuereinheit oder durch die arbeitstelleneigenen Steuereinrichtungen an die Sende-Empfangseinrichtungen und umgekehrt. Hierzu kann die Übertragung von Betriebsdaten beispielsweise durch Arbeitsunterbrechungen initiiert werden, die von der jeweiligen Steuereinrichtung der Arbeitsstellen oder der zentralen Steuereinheit an die Sende-Empfangseinrichtungen übermittelt werden. Ergänzend kann in regelmäßigen zeitlichen Intervallen eine Übermittlung der Betriebsdaten initiiert werden, um den Datenbestand auf den Transpondern der in der Textilmaschine verwendeten austauschbaren Komponenten zu aktualisieren.According to the characterizing part of claim 9, the jobs each have a control device, which with the transceiver devices keep in touch. Furthermore, the textile machine may have a central control unit which is in communication with the transceiver devices. Thus, the transmission of the operating data by the higher-level central control unit or by the workstation's own control devices to the transceiver devices and vice versa. For this purpose, the transmission of operating data can be initiated, for example, by work interruptions, which are transmitted from the respective control device of the workstations or the central control unit to the transceiver devices. In addition, a transmission of the operating data can be initiated at regular time intervals in order to update the database on the transponders of the exchangeable components used in the textile machine.

Bei dem Transponder kann es sich sowohl um einen aktiven als auch einen passiven Transponder handeln. Die Verwendung eines aktiven oder passiven Transponders richtet sich unter anderem nach der zu erwartenden Lebensdauer der Komponente sowie nach der erforderlichen Übertragungsreichweite der auf dem Transponder gespeicherten Betriebsdaten. Aktive Transponder sind mit einer eigenen Energieversorgung ausgestattet und weisen somit eine höhere Reichweite auf, als passive Transponder. Hingegen sind passive Transponder kostengünstiger.The transponder can be both an active and a passive transponder. The use of an active or passive transponder depends inter alia on the expected service life of the component and on the required transmission range of the operating data stored on the transponder. Active transponders are equipped with their own power supply and thus have a higher range than passive transponders. On the other hand, passive transponders are cheaper.

Vorzugsweise sind die Sende-Empfangseinrichtungen derart ausgebildet, dass die Betriebsdaten mehrerer Komponenten gleichzeitig ausgelesen werden können. Dies ist insbesondere dann von Vorteil, wenn beispielsweise eine Beurteilung von im Lagerbestand befindlichen Komponenten durchgeführt werden soll, da dieser Vorgang sich dadurch erheblich beschleunigen lässt.Preferably, the transceiver devices are designed such that the operating data of several components can be read out simultaneously. This is particularly advantageous if, for example, an assessment of components in stock is to be carried out, since this process can be accelerated considerably.

In Figur 1 ist eine Hälfte einer semiautomatischen Offenend-Rotorspinnmaschine 1 dargestellt. Solche Spinnmaschinen weisen eine Vielzahl von Arbeitsstellen 2 auf, die jeweils mit einer Spinnvorrichtung 3 sowie einer Spuleinrichtung 33 ausgestattet sind. In den Spinnvorrichtungen 3 wird das in Spinnkannen 28 vorgelegte Faserband 34 jeweils zu einem Faden 30 versponnen, der auf der Spuleinrichtung 33 zu einer Kreuzspule 22 aufgewickelt wird. Die Spuleinrichtungen 33 weisen dabei, wie an sich bekannt, jeweils einen Spulenrahmen 21 zum drehbaren Haltern der Hülse einer Kreuzspule 22, eine Spulenantriebswalze 23, eine Fadenchangiereinrichtung 26 sowie eine Einrichtung 7 zum Abheben der Kreuzspule 22 von der Spulenantriebswalze 23 auf.In FIG. 1 One half of a semiautomatic open-end rotor spinning machine 1 is shown. Such spinning machines have a plurality of jobs 2, which are each equipped with a spinning device 3 and a winding device 33. In the spinning devices 3, the fiber sliver 34 presented in spinning cans 28 is spun in each case into a yarn 30 which is wound on the winding device 33 to form a cross-wound bobbin 22. The winding devices 33 have, as is known, in each case a coil frame 21 for rotatably supporting the sleeve of a cross-wound bobbin 22, a bobbin drive roller 23, a Fadenchangiereinrichtung 26 and a device 7 for lifting the cross-wound bobbin 22 of the bobbin drive roller 23.

Die Einrichtung 7 ist beispielsweise als Schubkolbengetriebe ausgebildet, das über eine Pneumatikleitung 24, in die ein Elektromagnetventil 17 eingeschaltet ist, an eine (nicht dargestellte) Überdruckquelle angeschlossen ist.The device 7 is designed for example as a thrust piston, which is connected via a pneumatic line 24, in which a solenoid valve 17 is turned on, to a (not shown) overpressure source.

Im vorliegenden Ausführungsbeispiel erfolgt der Antrieb der Spulenantriebswalze 23 als Gruppenantrieb. Das heißt, es ist eine maschinenlange Antriebswelle vorgesehen, an der die einzelnen Spulenantriebswalzen 23 festgelegt sind. In alternativer Ausführungsform ist allerdings auch ein einzelmotorischer Antrieb der Spulenantriebswalze 23 möglich. In einem solchen Fall ist der Antrieb der Spulenantriebswalze 23 durch eine entsprechende Steuerleitung an die spinnstelleneigene Steuereinrichtung 9 angeschlossen.In the present embodiment, the drive of the bobbin drive roller 23 takes place as a group drive. That is, there is provided a machine-length drive shaft to which the individual reel drive rollers 23 are fixed. In an alternative embodiment, however, a single motor drive of the bobbin drive roller 23 is possible. In such a case, the drive of the bobbin drive roller 23 is connected by a corresponding control line to the spinning station's own control device 9.

Im Bereich der Spuleinrichtung 33 kann außerdem eine, an sich bekannte, (nicht dargestellte) Fadenhebeeinrichtung installiert sein. Eine solche Fadenhebeeinrichtung verhindert, dass der Faden während des Anspinnvorganges unbeabsichtigt durch die traversierende Fadenchangiereinrichtung 26 erfasst werden kann. Das heißt, die beispielsweise als klappbares Blech ausgebildete Fadenhebeeinrichtung hält den Faden 30 während des eigentlichen Anspinnvorganges zunächst im Abstand oberhalb der hin- und hergehenden Fadenchangiereinrichtung 26.In the area of the winding device 33 can also be a, known per se, (not shown) thread lifting device to be installed. Such a thread lifting device prevents the thread during the piecing process can be unintentionally detected by the traversing Fadenchangiereinrichtung 26. That is, for example, designed as a foldable sheet thread lifting device keeps the thread 30 during the actual piecing first at a distance above the reciprocating Fadenchangiereinrichtung 26th

Die Spinnvorrichtung 3 verfügt im Wesentlichen, wie bekannt, über einen Spinnrotor 4, eine Faserband-Auflösewalze 12 sowie einen Faserbandeinzugszylinder 14.As is known, the spinning device 3 has a spinning rotor 4, a sliver-opening roller 12 and a sliver-intake cylinder 14.

Gemäß dem Ausführungsbeispiel der Fig. 1 ist der Spinnrotor 4 beispielsweise in einer Stützscheibenlagerung 5 gelagert und wird über einen maschinenlangen Tangentialriemen 6 angetrieben.According to the embodiment of the Fig. 1 For example, the spinning rotor 4 is mounted in a support disk bearing 5 and is driven by a machine-tangential belt 6.

Zur Erfassung der Drehzahl des Spinnrotors 4 kann außerdem eine Sensoreinrichtung 8 vorgesehen sein, die dann über eine Signalleitung 40 an die Steuereinrichtung 9 angeschlossen ist. Die Faserband-Auflösewalze 12 wird vorzugsweise ebenfalls über einen maschinenlangen Tangentialriemen 13 beaufschlagt, während der Faserbandeinzugszylinder 14 über einen Antrieb 15 einzelmotorisch angetrieben wird.For detecting the rotational speed of the spinning rotor 4, a sensor device 8 can also be provided, which is then connected to the control device 9 via a signal line 40. The sliver-opening roller 12 is preferably also acted upon by a machine-tangential belt 13, while the sliver-picking cylinder 14 is driven by a motor 15 single motor.

Der Antrieb des Faserbandeinzugszylinders 14, beispielsweise ein Schrittmotor 15, ist über eine Steuerleitung 16 ebenfalls an die Steuereinrichtung 9 angeschlossen. Des Weiteren verfügen die Arbeitsstellen 2 jeweils über eine Fadenabzugseinrichtung 18, deren Antrieb 19 über eine Steuerleitung 20 mit der Steuereinrichtung 9 in Verbindung steht.The drive of the sliver feed cylinder 14, for example a stepper motor 15, is likewise connected to the control device 9 via a control line 16. Furthermore, the work stations 2 each have a thread withdrawal device 18, whose drive 19 is connected via a control line 20 to the control device 9.

Im Bereich der Arbeitsstelle 2 ist eine Sende-Empfangseinrichtung 38 angeordnet, die das berührungslose Auslesen und Beschreiben von Transpondern 37 ermöglicht, die an den austauschbaren Komponenten der Arbeitsstelle 2 angeordnet oder in diesen integriert sind, wie in Fig. 3 anhand des Spinnrotors 4 dargestellt. Die Sende-Empfangseinrichtung 38 steht über eine Steuerleitung 39 mit der spinnstelleneigenen Steuereinrichtung 9 in Verbindung.In the area of the workplace 2, a transceiver 38 is arranged, which allows the non-contact reading and writing of transponders 37, which are arranged on the replaceable components of the workstation 2 or integrated in this, as in Fig. 3 illustrated by the spinning rotor 4. The transceiver 38 is connected via a control line 39 with the spinning station's own control device 9 in connection.

In einer alternativen Ausführungsform, die in Fig. 2 dargestellt ist, ist der Spinnrotor 4 nicht in einer Stützscheibenlagerung 5 abgestützt, sondern in einer, lediglich schematisch angedeuteten Magnetlagerung. Der Spinnrotor 4 wird in einem solchen Fall vorzugsweise durch einen Einzelantrieb 31 beaufschlagt.In an alternative embodiment, the in Fig. 2 is shown, the spinning rotor 4 is not supported in a support disk bearing 5, but in a, only schematically indicated magnetic bearing. The spinning rotor 4 is preferably acted upon by a single drive 31 in such a case.

Der Spinnrotorantrieb 31 steht dabei über eine Steuerleitung 45 mit der Steuereinrichtung 9 in Verbindung. Wie im Ausführungsbeispiel gemäß Fig. 2 weiter dargestellt, kann auch die Faserband-Auflösewalze 12 einzelmotorisch angetrieben sein.The spinning rotor drive 31 is connected via a control line 45 to the control device 9 in connection. As in the embodiment according to Fig. 2 also shown, the sliver-opening roller 12 may be driven by a single motor.

Das heißt, innerhalb des Garniturringes der Faserband-Auflösewalze 12 ist beispielsweise ein Außenläuferantrieb 59 angeordnet, der über eine Steuerleitung 32 ebenfalls mit der Steuereinrichtung 9 verbunden ist.That is, within the Garniturringes the sliver-opening roller 12, for example, an external rotor drive 59 is arranged, which is also connected via a control line 32 to the control device 9.

Der Darstellung in Fig. 3 ist exemplarisch eine austauschbare Komponente der Arbeitsstelle 2, der Spinnrotor 4, zu entnehmen. Der Spinnrotor 4 ist auf der Außenseite der Spinntasse 35 mit einem passiven Transponder 37 versehen. Alternativ sind auch aktive Transponder verwendbar, das heißt, dass die Transponder eine eigene Stromversorgungsvorrichtung aufweisen. Dies beeinflusst die Reichweite, innerhalb der Daten vom Transponder empfangen und gesendet werden können.The representation in Fig. 3 is exemplified a replaceable component of the job 2, the spinning rotor 4, refer. The spinning rotor 4 is provided on the outside of the spinning cup 35 with a passive transponder 37. Alternatively, active transponders can be used, that is, the transponders have their own power supply device. This affects the range within which data can be received and sent by the transponder.

Die Figuren 4 und 5 zeigen weitere austauschbare Komponenten einer Offenend-Rotorspinnmaschine, wie eine Stützscheibe 58, eine Abzugsdüse 56, eine Kanalplatte 55 sowie eine Kanalplattenadapter 56, die jeweils mit einem Transponder 37 zur Betriebsdatenerfassung ausgestattet sindThe FIGS. 4 and 5 show further interchangeable components of an open-end rotor spinning machine, such as a support disk 58, a discharge nozzle 56, a channel plate 55 and a channel plate adapter 56, each equipped with a transponder 37 for operational data acquisition

Das erfindungsgemäße Verfahren wird anhand des Austausches des Spinnrotors 4 näher erläutert. Wird in eine Arbeitsstelle 2 ein neuer, bisher unbenutzter Spinnrotor 4 eingesetzt, so wird der an der Spinnrotortasse 35 angeordnete Transponder 37 bei der Zuführung zur Arbeitsstelle 2 durch die Sende-Empfangseinrichtung 38 detektiert, was zu einer Aktivierung des Transponders 37 führt. Die zu diesem Zeitpunkt in dem Transponder 37 hinterlegten Betriebsdaten werden ausgelesen und an die Steuereinrichtung 9 weitergeleitet. Bei den Betriebsdaten handelt es sich um Angaben über die bisherige Einsatzdauer, Einsatzbedingungen wie Rotordrehzahl, Durchsatz, Anzahl von Fadenbrüchen und dergleichen. Insbesondere Betriebsdaten, die dazu geeignet sind, das verschleißgradabhängige Verhalten des Spinnrotors zu charakterisieren.The inventive method will be explained in more detail with reference to the replacement of the spinning rotor 4. If a new, previously unused spinning rotor 4 is used in a workstation 2, the transponder 37 arranged on the spinning rotor cup 35 is detected by the transceiver 38 when it is fed to the workstation 2, which leads to an activation of the transponder 37. The stored at this time in the transponder 37 operating data are read and forwarded to the controller 9. The operating data are details of the previous service life, operating conditions such as rotor speed, throughput, number of thread breaks and the like. In particular, operating data which are suitable for characterizing the wear-degree-dependent behavior of the spinning rotor.

Da es sich, wie bereits erwähnt, um einen unbenutzten Spinnrotor 4 handelt, dessen Lebenszyklus mit seiner erstmaligen Verwendung in der Arbeitsstelle 2 beginnt, wird zunächst der Zeitpunkt der erstmaligen Inbetriebnahme des Spinnrotors 4 auf dem Transponder 37 gespeichert. Die hierzu notwendigen Betriebsdaten werden von der Steuereinrichtung 9 an die Sende-Empfangseinrichtung 38 der betroffenen Arbeitsstelle 2 weitergeleitet. Mit der Inbetriebnahme werden nun alle Betriebsdaten, die den Spinnrotor 4 unmittelbar betreffen und dessen Verschleißverhalten bestimmen, erfasst.Since it is, as already mentioned, an unused spinning rotor 4 whose life cycle begins with its first use in the workplace 2, the time of first start-up of the spinning rotor 4 is initially stored on the transponder 37. The operating data necessary for this purpose are forwarded by the control device 9 to the transceiver 38 of the workstation 2 concerned. With the commissioning now all operating data that directly affect the spinning rotor 4 and determine its wear behavior is detected.

Die Bereitstellung dieser Betriebsdaten erfolgt gleichfalls durch die Steuereinrichtung 9. Bei den zu erfassenden Betriebsdaten handelt es sich zum Beispiel um Partiedaten, insbesondere den Faserstoffeinsatz und die verarbeitete Menge an Faserband, die dem Spinnrotor 4 während seines Einsatzes an dieser Offenend-Rotorspinnmaschine 1 zugeführt wurde. Somit kann zu jedem beliebigen Zeitpunkt der Durchsatz der zuletzt verarbeiteten Partie oder der Gesamtdurchsatz des Spinnrotors 4 bestimmt-werden.The provision of this operating data is likewise effected by the control device 9. The operating data to be recorded are, for example, batch data, in particular the pulp feed and the processed amount of fiber sliver which was fed to the spinning rotor 4 during its use at this open-end rotor spinning machine 1. Thus, at any time the throughput of the last processed batch or the total throughput of the spinning rotor 4 can be determined.

Des Weiteren werden beispielsweise die von der Sensoreinrichtung 8 erfassten Drehzahlen des Spinnrotors 4 beziehungsweise die an der Steuereinrichtung 9 eingestellte Drehzahl an die Sende-Empfangeinrichtung 38 weitergeleitet und auf den Transponder 37 übertragen. Weiterhin wird die Anzahl von Fadenbrüchen an der Arbeitsstelle 2 erfasst und auf den Transponder 37 übertragen.Furthermore, for example, the rotational speeds of the spinning rotor 4 detected by the sensor device 8 or the rotational speed set on the control device 9 are forwarded to the transceiver device 38 and transmitted to the transponder 37. Furthermore, the number of yarn breaks is detected at the workplace 2 and transmitted to the transponder 37.

Dieser Informationsfluss wird über die gesamte Verweildauer des Spinnrotors 4 in der Arbeitsstelle 2 aufrechterhalten. Dabei werden die zu erfassenden Betriebsdaten stets beim Auftreten einer Arbeitsunterbrechung, zum Beispiel zu Beginn eines Spulenwechsels, aktualisiert, um eine lückenlose Erfassung der Betriebsdaten des Spinnrotors 4 sicherzustellen.This information flow is maintained over the entire residence time of the spinning rotor 4 in the workplace 2. In this case, the operating data to be detected are always updated when a work stoppage occurs, for example at the beginning of a bobbin change, in order to ensure complete detection of the operating data of the spinning rotor 4.

Bei einem erforderlichen Wechsel des Spinnrotors 4, beispielsweise auf Grund eines Partiewechsels, bleiben die in dem Transponder 37 hinterlegten Betriebsdaten erhalten. Wird zu einem späteren Zeitpunkt derselbe Spinnrotor 4 in eine andere Offenend-Rotorspinnmaschine eingebaut, so werden die über den bisherigen Lebenszyklus erfassten und gespeicherten Betriebsdaten des Spinnrotors 4 an dieser Textilmaschine wie bereits beschrieben ausgelesen und stehen unabhängig von der vorherigen Verwendung des Spinnrotors 4 zur Bewertung des Verschleißzustandes zur Verfügung.In a required change of the spinning rotor 4, for example due to a lot change, the stored in the transponder 37 operating data are retained. If the same spinning rotor 4 is installed at a later time in another open-end rotor spinning machine, the operating data of the spinning rotor 4 recorded and stored over the previous life cycle are read out on this textile machine as already described and are independent of the previous use of the spinning rotor 4 for evaluating the Wear state available.

Hierzu sind die in den Transpondern 37 der austauschbaren Komponenten hinterlegten Betriebsdaten unabhängig von deren Einsatz in den Arbeitsstellen 2 der Textilmaschine 1 auslesbar. Das Auslesen kann beispielsweise mittels eines Handgerätes oder dergleichen erfolgen, um auszutauschende Komponenten vor deren Einsatz in den Arbeitsstellen 2 kategorisieren zu können.For this purpose, the stored in the transponders 37 of the interchangeable components operating data regardless of their use in the jobs 2 of the textile machine 1 can be read out. The reading can be done for example by means of a hand-held device or the like in order to be able to categorize components to be exchanged before they are used in the workstations 2.

Das erfindungsgemäße Verfahren ist in entsprechender Weise zum Beispiel auch für die Faserband-Auflösewalze 12, die Stützscheibe 58, die Abzugsdüse 56, die Kanalplatte 55 oder den Kanalplattenadapter 57 der Offenend-Rotorspinnmaschine anwendbar.The inventive method is in a corresponding manner, for example, for the sliver-opening roller 12, the support plate 58, the Abzugsdüse 56, the channel plate 55 or the channel plate adapter 57 of the open-end rotor spinning machine applicable.
