- a spinning rotor rotates to spin a yarn at a high speed.
- different spinning rotors are required.
- the spinning rotor is a wearing part.
- the spinning rotors are usually interchangeable.
- the spinning rotors differ mainly in their diameter and shape. The diameter and shape influence the permissible speed. Smaller rotors can be operated at higher speeds. A large spinning rotor requires lower speeds because the higher centrifugal forces can otherwise lead to damage.
- the rotor diameter influences the possible yarn count.
- the DE 101 17 095 A1 discloses to provide the spinning rotor and other interchangeable machine components of spinning machinery with an identification tag. With an appropriate arrangement of the identification mark this can be detected automatically, so the configuration of a spinning station is automatically retrieved.

- the electric power supplied to the drive becomes continuous and the actual value profile of a quantity representing the energy supply is continuously compared with the desired value profile profile assigned to the respective operating phase.
- the detection occurs both during startup and during normal spinning operation. This should be detected disturbances due to contamination in the storage area of the spinning rotor. It is mentioned that, in principle, the rotational speed of the spinning rotor can be monitored to detect such disturbances. The deviations in the speed are, however, significantly lower than in the power supply.
- the object is achieved by a method for operating an open-end rotor spinning device with a replaceable, single-motor driven spinning rotor .
- the spinning rotor is accelerated from a first speed to a predetermined second speed with a predetermined power, and the acceleration time required for the acceleration from the first speed to the second speed is detected and evaluated as the evaluation quantity.
- the spinning rotor is accelerated with a predetermined power from a first speed for a predetermined acceleration time and the second speed reached in this time is detected and evaluated as an evaluation variable.
- the invention is based on the finding that the acceleration depends on the diameter of the spinning rotor.
- a small spinning rotor accelerates faster than a large spinning rotor due to its lower mass inertia.
- the diameter is a characteristic feature of the spinning rotor.
- an inserted spinning rotor can be identified on the basis of the evaluation value.
- the operational safety is increased because a wrongly inserted rotor can be detected.

- the detected evaluation variable is preferably compared with the reference value of the evaluation variable of the at least one spinning rotor having the predetermined diameter.
- the at least one spinning rotor having the predetermined diameter represents a given spinning rotor.
- a display is made.
- the reference value of the evaluation variable thus allows the simple determination of whether a spinning rotor with the predetermined diameter is arranged in the open-end rotor spinning device or not.
- the display can be in the form of a simple warning, for example, yellow or red lamp at the spinning station, or a text hint in a display. In addition to the displays can also be a shutdown of the spinning station.
- the permissible rotational speed of the spinning rotor is limited as a function of the detected evaluation variable. That is, it is ensured that an inserted spinning rotor is operated only at speeds that lead to no damage.
- a reference value of the evaluation variable may be assigned a limit speed.
- the reference value of the evaluation variable corresponds to a predetermined diameter of the spinning rotor. All spinning rotors that have a larger diameter are not operated at a speed greater than the limit speed.
- the present invention also relates to an open-end rotor spinning device.

Description
Die vorliegende Erfindung betrifft ein Verfahren zum Betreiben einer Offenend-Rotorspinneinrichtung mit einem austauschbaren, einzelmotorisch angetriebenen Spinnrotor und eine Offenend-Rotorspinneinrichtung mit einem austauschbaren Spinnrotor und einem einzelmotorischen Antrieb zum Antreiben des Spinnrotors.The present invention relates to a method for operating an open-end rotor spinning device with a replaceable, single-motor driven spinning rotor and an open-end rotor spinning device with an exchangeable spinning rotor and a single-motor drive for driving the spinning rotor.
In Offenend-Rotorspinneinrichtungen rotiert ein Spinnrotor zum Spinnen eines Fadens mit hoher Drehzahl. In Abhängigkeit von den gewünschten Spinn- und Garnparametern werden unterschiedliche Spinnrotoren benötigt. Außerdem handelt sich bei dem Spinnrotor um ein Verschleißteil. Aus diesem sind die Spinnrotoren üblicherweise austauschbar. Die Spinnrotoren unterscheiden sich dabei vor allem in ihrem Durchmesser und in ihrer Form. Der Durchmesser und die Form beeinflussen dabei die zulässige Drehzahl. Kleinere Rotoren können mit höheren Drehzahlen betrieben werden. Ein großer Spinnrotor erfordert geringere Drehzahlen, da die höheren Fliehkräfte ansonsten zu Beschädigungen führen können. Ferner beeinflusst der Rotordurchmesser die mögliche Garnfeinheit.In open-end rotor spinning devices, a spinning rotor rotates to spin a yarn at a high speed. Depending on the desired spinning and yarn parameters, different spinning rotors are required. In addition, the spinning rotor is a wearing part. For this, the spinning rotors are usually interchangeable. The spinning rotors differ mainly in their diameter and shape. The diameter and shape influence the permissible speed. Smaller rotors can be operated at higher speeds. A large spinning rotor requires lower speeds because the higher centrifugal forces can otherwise lead to damage. Furthermore, the rotor diameter influences the possible yarn count.

Es ist die Aufgabe der vorliegenden Erfindung, die Betriebssicherheit einer Offenend-Rotorspinneinrichtung auf einfache Weise zu erhöhen.It is the object of the present invention to increase the reliability of an open-end rotor spinning device in a simple manner.
Die Aufgabe wird durch ein Verfahren zum Betreiben einer Offenend-Rotorspinneinrichtung mit einem austauschbaren, einzelmotorisch angetriebenen Spinnrotor gelöst. Bei dem Verfahren wird der Spinnrotor mit einer vorgegebenen Leistung von einer ersten Drehzahl auf eine vorgegebene zweite Drehzahl beschleunigt und die für die Beschleunigung von der ersten Drehzahl auf die zweite Drehzahl benötigte Beschleunigungszeit wird erfasst und als Auswertegröße ausgewertet. Alternativ wird der Spinnrotor mit einer vorgegeben Leistung von einer ersten Drehzahl für eine vorgegebene Beschleunigungszeit beschleunigt und die in dieser Zeit erreichte zweite Drehzahl erfasst und als Auswertegröße ausgewertet.The object is achieved by a method for operating an open-end rotor spinning device with a replaceable, single-motor driven spinning rotor . In the method, the spinning rotor is accelerated from a first speed to a predetermined second speed with a predetermined power, and the acceleration time required for the acceleration from the first speed to the second speed is detected and evaluated as the evaluation quantity. Alternatively, the spinning rotor is accelerated with a predetermined power from a first speed for a predetermined acceleration time and the second speed reached in this time is detected and evaluated as an evaluation variable.
Der Erfindung liegt die Erkenntnis zu Grunde, dass die Beschleunigung von dem Durchmesser des Spinnrotors abhängt. Ein kleiner Spinnrotor beschleunigt aufgrund seiner geringeren Massenträgheit schneller als ein großer Spinnrotor. Der Durchmesser ist ein charakteristisches Merkmal des Spinnrotors. Damit kann anhand der Auswertegröße ein eingelegter Spinnrotor identifiziert werden. Die Betriebssicherheit wird erhöht, da ein falsch eingelegter Rotor erkannt werden kann. Die Erfindung ermöglicht damit auf einfache Weise einen Rotor, der nicht zu den eingestellten Spinn- und Garnparametern passt, zu identifizieren; insbesondere kann verhindert werden, dass ein Rotor nicht mit zu hohen Drehzahlen betrieben wird.The invention is based on the finding that the acceleration depends on the diameter of the spinning rotor. A small spinning rotor accelerates faster than a large spinning rotor due to its lower mass inertia. The diameter is a characteristic feature of the spinning rotor. Thus, an inserted spinning rotor can be identified on the basis of the evaluation value. The operational safety is increased because a wrongly inserted rotor can be detected. The invention thus makes it possible in a simple way to identify a rotor which does not match the set spinning and yarn parameters; In particular, it can be prevented that a rotor is not operated at too high speeds.
Die erste Drehzahl kann Null oder eine von Null verschiedene Drehzahl sein. Eine von Null verschiedene Drehzahl ist jedoch von Vorteil. Haftreibungseffekte, die beim Hochlauf aus dem Stillstand überwunden werden müssten und die Beschleunigungszeit beeinflussen würden, können so vermieden werden. Vorzugsweise ist die erste Drehzahl kleiner als die zweite Drehzahl. Das heißt, die Beschleunigung ist positiv.
Im Prinzip kann, um eine durchmesserabhängige Beschleunigungszeit zu erhalten, die erste Drehzahl auch größer sein als die zweite Drehzahl. Die Beschleunigung wäre dann negativ. Die erste Drehzahl und die zweite Drehzahl sollten jedoch kleiner sein als eine Grenzdrehzahl. Diese Grenzdrehzahl ergibt sich aus der zulässigen Drehzahl des Spinnrotors mit dem größten Durchmesser, der in der Offenend-Rotorspinneinrichtung montierbar ist.The first speed may be zero or a non-zero speed. However, a nonzero speed is beneficial. Stiction effects during startup can be overcome from a standstill and affect the acceleration time can be avoided. Preferably, the first speed is less than the second speed. That means the acceleration is positive.
In principle, to obtain a diameter-dependent acceleration time, the first speed may also be greater than the second speed. The acceleration would then be negative. However, the first speed and the second speed should be less than a limit speed. This limit speed results from the permissible speed of the spinning rotor with the largest diameter, which is mountable in the open-end rotor spinning device.
Vorteilhafterweise wird für mindestens einen Spinnrotor mit einem vorgegebenen Durchmesser ein Referenzwert der Auswertegröße ermittelt. Die erfasste Auswertegröße wird vorzugsweise mit dem Referenzwert der Auswertegröße des mindestens einen Spinnrotors mit dem vorgegebenen Durchmesser verglichen.Advantageously, a reference value of the evaluation variable is determined for at least one spinning rotor having a predetermined diameter. The detected evaluation variable is preferably compared with the reference value of the evaluation variable of the at least one spinning rotor having the predetermined diameter.
Gemäß einer vorteilhaften Ausführungsform des erfindungsgemäßen Verfahrens stellt der mindestens eine Spinnrotor mit dem vorgegebenen Durchmesser einen vorgegebenen Spinnrotor dar. Bei einer vorgegebenen Abweichung der erfassten Auswertegröße von dem Referenzwert der Auswertegröße erfolgt eine Anzeige. Der Referenzwert der Auswertegröße ermöglicht also die einfache Bestimmung, ob ein Spinnrotor mit dem vorgegebenen Durchmesser in der Offenend-Rotorspinneinrichtung angeordnet ist oder eben nicht. Die Anzeige kann in Form eines einfachen Warnhinweises erfolgen, zum Beispiel gelbe oder rote Lampe an der Spinnstelle, oder ein Texthinweis in einem Display. Zusätzlich zu den Anzeigen kann auch eine Stillsetzung der Spinnstelle erfolgen.According to an advantageous embodiment of the method according to the invention, the at least one spinning rotor having the predetermined diameter represents a given spinning rotor. With a predetermined deviation of the detected evaluation variable from the reference value of the evaluation quantity, a display is made. The reference value of the evaluation variable thus allows the simple determination of whether a spinning rotor with the predetermined diameter is arranged in the open-end rotor spinning device or not. The display can be in the form of a simple warning, for example, yellow or red lamp at the spinning station, or a text hint in a display. In addition to the displays can also be a shutdown of the spinning station.
Gemäß einer weiteren Ausführungsform des erfindungsgemäßen Verfahrens wird in Abhängigkeit von der erfassten Auswertegröße die zulässige Drehzahl des Spinnrotors begrenzt. Das heißt, es wird sichergestellt, dass ein eingelegter Spinnrotor nur bei Drehzahlen betrieben wird, die zu keinen Beschädigungen führen. Hierzu kann einem Referenzwert der Auswertegröße eine Grenzdrehzahl zugeordnet sein. Der Referenzwert der Auswertegröße entspricht einem vorgegebenen Durchmesser des Spinnrotors. Alle Spinnrotoren, die einen größeren Durchmesser haben, werden nicht bei einer Drehzahl betrieben, die größer ist als die Grenzdrehzahl.According to a further embodiment of the method according to the invention, the permissible rotational speed of the spinning rotor is limited as a function of the detected evaluation variable. That is, it is ensured that an inserted spinning rotor is operated only at speeds that lead to no damage. For this purpose, a reference value of the evaluation variable may be assigned a limit speed. The reference value of the evaluation variable corresponds to a predetermined diameter of the spinning rotor. All spinning rotors that have a larger diameter are not operated at a speed greater than the limit speed.
Die vorliegende Erfindung betrifft außerdem eine Offenend-Rotorspinneinrichtung. Die Offenend-Rotorspinneinrichtung umfasst erfindungsgemäß eine Steuereinrichtung, die den Antrieb des Spinnrotors so ansteuert, dass der Spinnrotor mit einer vorgegebenen Leistung von einer ersten Drehzahl auf eine zweite Drehzahl beschleunigt wird, und die die für die Beschleunigung von der ersten Drehzahl auf die zweite Drehzahl benötigte Beschleunigungszeit erfasst und als Auswertegröße ausgewertet wird, oder dass der Spinnrotor mit einer vorgegeben Leistung von einer ersten Drehzahl für eine vorgegebene Beschleunigungszeit beschleunigt wird und die in dieser Zeit erreichte zweite Drehzahl erfasst und als Auswertegröße ausgewertet wird. Die Steuereinrichtung umfasst einen Speicher, in dem ein Referenzwert der Auswertegröße mindestens eines Spinnrotors mit einem vorgegebenen Durchmesser gespeichert ist. Die Steuereinrichtung ist ferner dazu ausgebildet, die erfasste Auswertegröße mit dem Referenzwert der Auswertegröße des mindestens einen Spinnrotors mit dem vorgegebenen Durchmesser zu vergleichen.The present invention also relates to an open-end rotor spinning device. The open-end rotor spinning device according to the invention comprises a control device which controls the drive of the spinning rotor so that the spinning rotor with a predetermined power is accelerated from a first speed to a second speed, and the required for the acceleration of the first speed to the second speed Acceleration time is detected and evaluated as evaluation value, or that the spinning rotor is accelerated with a predetermined power of a first speed for a given acceleration time and the second speed reached in this time is detected and evaluated as an evaluation variable. The control device comprises a memory in which a reference value of the evaluation variable of at least one spinning rotor having a predetermined diameter is stored. The control device is further configured to compare the detected evaluation variable with the reference value of the evaluation variable of the at least one spinning rotor having the predetermined diameter.
Die erfindungsgemäße Offenend-Rotorspinneinrichtung lässt sich leicht realisieren. Bekannte Offenend-Rotorspinneinrichtungen mit einem einzelmotorischen Antrieb verfügen im Regelfall bereits über eine Steuereinrichtung mit einem Speicher. Die erfindungsgemäße Ausbildung lässt sich leicht durch eine Softwareanpassung und die Speicherung der benötigten Referenzwerte umsetzen. Die für die Erfindung notwendige Drehzahl und Zeiterfassung sind in der Regel bereits vorhanden. Zusätzliche Einrichtungen, wie Markierungen oder Sensoren, sind nicht erforderlich.The open-end rotor spinning device according to the invention can be implemented easily.

Additional facilities, such as markers or sensors, are not required.

Um die Anzeige zu generieren, können gegebenenfalls vorhandene Anzeigemittel verwendet beziehungsweise angepasst werden.Preferably, the at least one spinning rotor having the predetermined diameter represents a predetermined spinning rotor and the control device is designed to generate a display for a given deviation of the detected evaluation variable from the reference value of the evaluation variable. In order to generate the display, possibly existing display means can be used or adapted.
Die Steuereinrichtung ist vorzugsweise dazu ausgebildet, in Abhängigkeit von der erfassten Auswertegröße die zulässige Drehzahl des Spinnrotors zu begrenzen. Mit anderen Worten, die Steuereinheit sorgt dafür, dass eine Grenzdrehzahl nicht überschritten wird. Die Grenzdrehzahl hängt von der erfassten Auswertegröße und damit von dem Durchmesser des Spinnrotors ab. Die Begrenzung der Drehzahl dient ausschließlich der Betriebssicherheit. Garn- und Spinnparameter können ansonsten frei gewählt werden.The control device is preferably designed to limit the permissible rotational speed of the spinning rotor as a function of the detected evaluation variable. In other words, the control unit ensures that a limit speed is not exceeded. The limit speed depends on the detected evaluation value and thus from the diameter of the spinning rotor. The limitation of the speed is solely for operational safety. Yarn and spinning parameters can otherwise be chosen freely.
