Description

Verfahren zum Betreiben einer Arbeitsstelle einer semiautomatischen Offenend-Spinnmaschine bzw. Arbeitsstelle zur Durchführung des Verfahrens (siehe EP-A-1 749 906).Method for operating a workstation of a semiautomatic open-end spinning machine or workstation for carrying out the method (see EP-A-1 749 906).

Die Erfindung betrifft ein Verfahren zum Betreiben einer Arbeitsstelle einer semiautomatischen Offenend-Spinnmaschine mit den Merkmalen des Oberbegriffes des Anspruches 1 bzw. eine Arbeitsstelle mit den Merkmalen des Oberbegriffes des Anspruches 5.The invention relates to a method for operating a workstation of a semi-automatic open-end spinning machine having the features of the preamble of claim 1 or a workstation having the features of the preamble of claim 5.

Semiautomatische Offenend-Spinnmaschinen sind bekannt und beispielsweise in der DE 10 2005 036 485 A1 , auch veröffentlicht als EP 1 749 906 A2 , ausführlich beschrieben.Semiautomatic open-end spinning machines are known and, for example in the DE 10 2005 036 485 A1 , also published as EP 1 749 906 A2 , described in detail.

Derartige Textilmaschinen unterscheiden sich von den in der Textilindustrie weit verbreiteten vollautomatischen Offenend-Spinnmaschinen unter anderem dadurch, dass sie kein fahrbares Serviceaggregat aufweisen, das die Arbeitsstellen dieser Textilmaschinen im Bedarfsfall selbsttätig versorgt.Such textile machines differ from the widely used in the textile industry fully automatic open-end spinning machines, inter alia, in that they have no mobile service unit that supplies the jobs of these textile machines when needed automatically.

Das bedeutet, bei semiautomatischen Offenend-Spinnmaschinen werden Bedienarbeiten, die bei vollautomatischen Offenend-Spinnmaschinen durch das entlang den Arbeitsstellen verfahrbare Serviceaggregat ausgeführt wurden, durch das Bedienpersonal manuell erledigt.This means that in semiautomatic open-end spinning machines, operating tasks that were carried out in the case of fully automatic open-end spinning machines by the service unit that can be moved along the work stations are performed manually by the operating personnel.

Nach einem Fadenbruch oder einer kontrollierten Spinnunterbrechung infolge eines Fadenfehlers wird zum Beispiel das auf die Kreuzspule aufgelaufene Fadenende durch die Bedienperson gesucht, maßgerecht abgelängt, vorbereitet und zum Wiederanspinnen in die Offenend-Spinnvorrichtung eingeführt. Anschließend wird, ebenfalls durch die Bedienperson, der eigentliche Anspinnprozess, der automatisch abläuft, gestartet. Da für das Bedienpersonal nicht immer erkennbar ist, wie lang ein Fadenfehler, der zu der Spinnunterbrechung führte, eigentlich ist, und vermieden werden sollte, dass fehlerhaftes Garn auf der Kreuzspule verbleibt, wickelt das Bedienpersonal in der Regel vorsichtshalber "reichlich" Fadenlänge von der Kreuzspule ab.
Das heißt, bei solchen semiautomatischen Offenend-Spinnmaschinen wird nach Spinnunterbrechungen oft viel Garn wieder von der Kreuzspule abgewickelt, das eigentlich einwandfrei ist und auf der Kreuzspule bleiben könnte.
After a yarn breakage or a controlled spinning interruption due to a yarn defect, for example, the yarn end accumulated on the cheese is searched by the operator, cut to length, prepared and introduced for re-spinning in the open-end spinning device. Subsequently, also by the operator, the actual piecing process, which runs automatically, started. Since operating personnel are not always aware of how long a thread defect that led to the spinning interruption actually is, and it should be avoided that defective yarn remains on the cheese, the operator wraps As a rule, as a precaution, "abundant" thread length from the cross-wound bobbin.
That is, in such semiautomatic open-end spinning machines often after spinning interruptions much yarn is unwound from the cheese again, which is actually perfect and could remain on the cheese.

Die DE 10 2004 013 776 A1 betrifft eine vollautomatische Offenend-Spinnmaschine, bei der beim Auftreten eines Fadenfehlers kein Bedienereingriff stattfindet. Hier wird beim Auftreten einer Sollwertabweichung eine Abspullänge zwischen der Stelle des ersten Auftretens der Sollwertabweichung bis zu einem danach produzierten Garnende ermittelt.The DE 10 2004 013 776 A1 relates to a fully automatic open-end spinning machine in which no operator intervention takes place when a thread error occurs. Here, when a setpoint deviation occurs, a take-off length between the point of the first occurrence of the setpoint deviation and a yarn end produced thereafter is determined.

Im Zusammenhang mit so genannten Kreuzspulautomaten, die bekanntlich Spinnkopse, die auf Ringspinnmaschinen erstellt wurden und relativ wenig Garn enthalten, zu großvolumigen Kreuzspulen umspulen und dabei das Garn auf Fadenfehler hin überprüfen, ist bereits ein Verfahren bekannt, mittels dessen dafür gesorgt wird, dass nach einem Fadenschnitt jeweils automatisch nur soviel Garn von der Kreuzspule abgewickelt wird, dass sichergestellt ist, dass der Fadenfehler vollständig ausgereinigt wird.In connection with so-called cross-winding machines, which are known spin-on spinning cops, which were created on ring spinning machines and contain relatively little yarn to large-volume cheeses and thereby check the yarn for thread defects, a method is already known, by means of which it is ensured that after a Thread cutting automatically only as much yarn is unwound from the cross-wound bobbin that it is ensured that the thread defect is completely cleaned.

Bei diesem in der DE 196 40 184 B4 beschriebenen Verfahren wird beim Auftreten eines Garnfehlers zunächst die Länge des fehlerbehafteten Fadens zwischen dem Zeitpunkt des Auftretens des Fehlers und dem Zeitpunkt des Fadenschnitts ermittelt und anschließend der fehlerbehaftete, auf die Kreuzspule aufgelaufene Faden mittels einer spulstelleneigenen Saugdüse abgesaugt, während die Kreuzspule entgegen ihrer Wickelrichtung rotiert wird.
Die Saugdüse ist mit einem Sensor ausgestattet, der den Eintritt des Fadens in die Saugdüse detektiert.
Das Abwickeln des Fadens von der Kreuzspule wird gestoppt, wenn auf Basis der eingangs ermittelten fehlerbehafteten Fadenlänge eine solche Fadenlänge in die Saugdüse eingesaugt ist, dass sichergestellt ist, dass im Rahmen des anschließenden pneumatischen Verbindens des auflaufspulenseitigen Fadenendes mit einem ablaufspulenseitigen Fadenende die fehlerbehaftete Fadenlänge herausgeschnitten ist.
In this in the DE 196 40 184 B4 described method is the occurrence of a yarn defect first determined the length of the faulty thread between the time of the occurrence of the error and the time of thread cutting and then sucked the faulty, accumulated on the cheese thread by means of a spool own suction nozzle, while the cheese is rotated counter to its winding direction ,
The suction nozzle is equipped with a sensor that detects the entry of the thread into the suction nozzle.
The unwinding of the thread from the cross-wound bobbin is stopped, if based on the initially determined erroneous thread length such a thread length is sucked into the suction nozzle, which ensures that the defective thread length is cut out in the context of the subsequent pneumatic connection of the package-side yarn end with a supply-side yarn end.

Ausgehend vom vorgenannten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, ein Verfahren bzw. eine Arbeitsstelle zu entwickeln, durch das/die gewährleistet ist, dass bei einer Spinnunterbrechung an einer Arbeitsstelle einer semiautomatischen Offenend-Spinnmaschine infolge eines Fadenfehlers das Bedienpersonal auf einfache und sichere Weise erkennen kann, wann die fehlerbehaftete Fadenlänge wieder von der Kreuzspule abgewickelt ist.Based on the above-mentioned prior art, the present invention seeks to develop a method or a work by which ensures that at a spinning break at a workstation of a semi-automatic open-end spinning machine due to a thread error, the operator to simple and secure Way can recognize when the faulty thread length is unwound from the cheese again.

Diese Aufgabe wird erfindungsgemäß durch ein Verfahren gelöst, das die im Anspruch 1 beschriebenen Merkmale aufweist bzw. durch eine Arbeitsstelle zur Durchführung des erfindungsgemäßen Verfahrens, die über die Merkmale des Anspruches 5 verfügt.This object is achieved by a method having the features described in claim 1 or by a job for performing the method according to the invention, which has the features of claim 5.

Vorteilhafte Ausgestaltungen des erfindungsgemäßen Verfahrens sind Gegenstand der Unteransprüche 2 - 4.
Vorteilhafte Ausführungsformen der erfindungsgemäßen Arbeitsstelle sind in den Unteransprüchen 6 - 8 beschrieben.
Advantageous embodiments of the method according to the invention are the subject of the dependent claims 2-4.
Advantageous embodiments of the workstation according to the invention are described in the subclaims 6-8.

Wie im Anspruch 1 dargelegt, wird der laufende Faden durch einen Fadenreiniger auf Fadenfehler hin überwacht. Beim Auftreten eines Fadenfehlers wird nicht nur die Länge des fehlerhaften Fadens, die auf die Kreuzspule aufläuft, durch einen Arbeitsstellenrechner ermittelt und der Spinnprozess an der betreffenden Arbeitsstelle unterbrochen, sondern beim anschließend manuellen Abwickeln der fehlerhaften Fadenlänge von der Kreuzspule wird durch eine Signaleinrichtung auch exakt angezeigt, wann die fehlerhafte Fadenlänge wieder vollständig von der Kreuzspule abgewickelt ist.
Das heißt, das Bedienpersonal wird im Bedarfsfall durch die Signalrichtung stets zweifelsfrei darüber informiert, ob bereits die gesamte fehlerhafte Fadenlänge von der Kreuzspule abgewickelt ist, oder ob noch fehlerhafte Fadenlänge auf der Kreuzspule ist, die im Interesse einer einwandfreien Kreuzspule noch von der Kreuzspule abgewickelt werden muss.
Aufgrund des Signals der Signaleinrichtung ist es für das Bedienpersonal möglich, die von der Kreuzspule wieder abzuwickelnde Fadenlänge relativ exakt einzuhalten und damit zu minimieren, mit der Folge, dass der im Zusammenhang mit dem Ausreinigen von Fadenfehlern anfallende Fadenabfall vermindert wird, was zu einer optimalen Nutzung des Vorlagematerials führt. Wie im Anspruch 2 beschrieben, ist in vorteilhafter Ausbildung vorgesehen, dass der Spinnprozess an der betreffenden Arbeitsstelle beim Auftreten eines Fadenfehlers durch Stoppen der Faserbandzufuhr in die Spinnvorrichtung unterbrochen wird. Zu diesem Zweck wird durch den Arbeitsstellenrechner einfach der einzelmotorische Antrieb des Faserbandzuführzylinders abgeschaltet und damit die Einzelfaserzuspeisung in den Spinnrotor unterbrochen.
As stated in claim 1, the current thread is monitored by a thread cleaner on thread error out. When a thread error occurs not only the length of the faulty thread that runs onto the cheese, determined by a workstation and the spinning process is interrupted at the relevant job, but during manual unwinding of the faulty thread length of the cheese is also displayed by a signal device exactly when the faulty thread length is completely unwound from the cheese again.
That is, the operator is informed in case of need by the signal direction always beyond doubt whether already the entire faulty thread length of the cross-wound bobbin is unwound, or whether there is still faulty thread length on the cheese, which still has to be unwound from the cross-wound bobbin in the interest of a perfect cheese.
Due to the signal of the signaling device, it is possible for the operator to maintain relatively accurate to be handled by the cheese reel yarn length and thus minimize, with the result that incurred in connection with the cleaning of yarn defects thread waste is reduced, resulting in optimal use of the original material. As described in claim 2, it is provided in an advantageous embodiment that the spinning process is interrupted at the job concerned in the occurrence of a yarn defect by stopping the sliver feed into the spinning device. For this purpose, the single-motor drive of the sliver feed cylinder is simply switched off by the workstation computer and thus the single-fiber feed into the spinning rotor is interrupted.

Wie im Anspruch 3 dargelegt, wertet der Arbeitsstellenrechner die Signale des Fadenreinigers sowie die Signale eines Sensors der einzelmotorisch angetriebenen Fadenabzugseinrichtung aus. Das heißt, durch den Arbeitsstellenrechner werden anhand der Signale des Sensors der Fadenabzugseinrichtung sowohl die Länge des fehlerhaften Fadens, die auf die Kreuzspule aufgelaufen ist, als auch die Gesamtfadenlänge der Kreuzspule ermittelt.
Aus den bekannten Garnparametern sowie der Gesamtfadenlänge berechnet der Arbeitsstellenrechner anschließend den augenblicklichen Durchmesser der Kreuzspule, anhand dessen der Arbeitsstellenrechner dann ermittelt, wie oft die Kreuzspule entgegen ihrer Wickelrichtung rotiert werden muss, um sicherzustellen, dass die fehlerhafte Fadenlänge wieder abgewickelt ist.
As set forth in claim 3, the workstation computer evaluates the signals of the thread cleaner and the signals of a sensor of the single-motor driven thread withdrawal device. That is, by the workstation computer are determined based on the signals of the sensor of the thread take-off both the length of the faulty thread that has accumulated on the cheese, as well as the total thread length of the cheese.
From the known yarn parameters and the total yarn length calculates the workstation computer then the current diameter of the cheese, based on which the workstation then determines how often the cheese must be rotated counter to its winding direction to ensure that the faulty thread length is unwound again.

Wie im Anspruch 4 dargelegt, sind an den Arbeitsstellenrechner außerdem eine Sensoreinrichtung und eine Signaleinrichtung angeschlossen.
Die Sensoreinrichtung erfasst, insbesondere wenn die Kreuzspule zum Abwickeln des fehlerhaften Fadens manuell entgegen der Wickelrichtung rotiert wird, die Richtung und die Winkelgrade der Rotationen der Kreuzspule.
Die Signaleinrichtung zeigt anschließend an, wann die Kreuzspule unter Berücksichtigung des jeweiligen Kreuzspulendurchmessers ausreichend in Abwickelrichtung rotiert ist, um sicherzustellen, dass das fehlerhafte Fadenstück von der Kreuzspule abgewickelt ist und abgetrennt werden kann.
As set forth in claim 4, a sensor device and a signaling device are also connected to the workstation computer.
The sensor device detects, in particular when the cross-wound bobbin for unwinding the faulty thread, manually against the Winding direction is rotated, the direction and the angular degrees of the rotations of the cheese.
The signaling device then indicates when the cross-wound bobbin is sufficiently rotated in the unwinding direction, taking into account the respective cross-coil diameter, to ensure that the faulty piece of thread is unwound from the cross-wound bobbin and can be separated.

Die Arbeitsstellen zum Durchführen des erfindungsgemäßen Verfahrens weisen, wie im Anspruch 5 beschrieben, jeweils eine Spinnvorrichtung zum Herstellen eines Fadens, eine einzelmotorisch angetriebene Fadenabzugseinrichtung sowie eine Spulvorrichtung zum Erstellen von Kreuzspulen auf.
Außerdem sind die zahlreichen Arbeitsstellen der semiautomatischen Offenend-Spinnmaschine jeweils mit einer Signaleinrichtung, einem Fadenreiniger zum Überwachen des laufenden Fadens, einem Sensor zum Ermitteln der durch die Fadenabzugseinrichtung aus der Spinnvorrichtung abgezogenen Fadenlänge sowie einer Sensoreinrichtung, die die Rotation der Kreuzspule erfasst, ausgestattet. Diese stehen über Signalleitungen mit einem Arbeitsstellenrechner in Verbindung, der die Signaleinrichtung aktiviert, wenn die fehlerhafte Fadenlänge wieder von der Kreuzspule abgewickelt ist.
Derartig ausgestattete Arbeitsstellen erleichtern dem Bedienpersonal nicht nur die Arbeit beim Beseitigen eines Fadenfehlers, weil das Bedienpersonal im Bedarfsfall durch die Signaleinrichtung stets sofort und exakt darüber informiert wird, wann die gesamte fehlerhafte Fadenlänge von der Kreuzspule abgewickelt ist, sondern ermöglichen auch eine optimale Nutzung des Vorlagematerials.
Das heißt, das Aufleuchten der Signaleinrichtung bei Erreichen der abzuwickelnden, fehlerhaften Fadenlänge führt dazu, dass auf einfache Weise vermieden werden kann, dass unnötig Faden von der Kreuzspule abgewickelt wird.
The jobs for performing the method according to the invention, as described in claim 5, each have a spinning device for producing a yarn, a single-motor driven yarn withdrawal device and a winding device for creating cheeses on.
In addition, the numerous work stations of the semi-automatic open-end spinning machine are each equipped with a signaling device, a thread cleaner for monitoring the running thread, a sensor for determining the withdrawn by the thread withdrawal device from the spinning device yarn length and a sensor device that detects the rotation of the cheese. These are connected via signal lines with a workstation computer in connection, which activates the signaling device when the faulty thread length is unwound from the cross-wound bobbin again.
Such equipped workstations not only facilitate the operator's work when eliminating a thread error, because the operator is informed immediately if necessary by the signal device immediately and exactly when the entire faulty thread length is unwound from the cheese, but also allow optimal use of the original material ,
That is, the lighting up of the signal device upon reaching the unwinding, erroneous thread length results in that it can be easily avoided that unnecessary thread is unwound from the cross-wound bobbin.

Wie im Anspruch 6 beschrieben, ist in vorteilhafter Ausführungsform vorgesehen, dass die Signaleinrichtung in den elektronischen Fadenreiniger integriert ist.As described in claim 6, it is provided in an advantageous embodiment that the signal device is integrated in the electronic thread cleaner.

Da solche Fadenreiniger in der Regel ohnehin mit wenigstens einer optischen Anzeigeeinrichtung, beispielsweise einer farbigen LED-Leuchte, ausgestattet sind, bietet sich an, als Signaleinrichtung eine solche LED-Leuchte zu verwenden, die im Ereignisfall in einer vorgebbaren Farbe aufleuchtet.Since such thread cleaners are usually anyway equipped with at least one optical display device, for example a colored LED light, it makes sense to use such a LED light as a signaling device which lights up in a predefinable color in the event of an incident.

Wie in den Ansprüchen 7 und 8 dargelegt, ist die Sensoreinrichtung, die insbesondere bei der manuellen Rotation der Kreuzspule den Drehwinkel und die Drehrichtung der Kreuzspule erfasst, im Bereich der Spulvorrichtung der Arbeitsstelle angeordnet und verfügt vorzugsweise über einen am Spulenrahmen angeordneten Hallsensor sowie wenigstens ein in einen rotierbaren Hülsenteller integriertes Permanentmagnetelement.
Derartige Sensoreinrichtungen sind insbesondere im Zusammenhang mit Kreuzspulautomaten seit langem bekannt und stellen kostengünstige, in der Praxis bewährte Bauelemente dar.
As set out in claims 7 and 8, the sensor device, which detects the angle of rotation and the direction of rotation of the cheese in particular during the manual rotation of the cross-wound bobbin, is arranged in the region of the winding device of the work station and preferably has a Hall sensor arranged on the creel and at least one in a rotatable sleeve plate integrated permanent magnet element.
Such sensor devices have been known for a long time, in particular in connection with reciprocating machines, and are cost-effective, proven components in practice.

In Fig.1 ist in Seitenansicht und in Fig.2 schematisch in Vorderansicht eine Arbeitsstelle 2 einer semiautomatischen Offenend-Rotorspinnmaschine 1 dargestellt.
Derartige Textilmaschinen verfügen, wie bekannt, über eine Vielzahl gleichartig ausgebildeter, in Reihe nebeneinander angeordneter Arbeitsstellen 2, die als wesentliche Funktionselemente jeweils eine Spinnvorrichtung 3 sowie eine Spuleinrichtung 33 aufweisen.
In Fig.1 is in side view and in Fig.2 schematically shown in front view a job 2 a semi-automatic open-end rotor spinning machine 1.
Such textile machines have, as is known, a plurality of identically formed, in series juxtaposed workstations 2, each having a spinning device 3 and a winding device 33 as essential functional elements.

In der Spinnvorrichtung 3 wird ein in einer Spinnkanne 28 vorgelegtes Faserband 34 zu einem Faden 30 versponnen, der anschließend auf der Spuleinrichtung 33 zu einer Kreuzspule 22 aufgewickelt wird.
Die Spuleinrichtungen 33 weisen zu diesem Zweck, 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.
Die Einrichtung 7 ist beispielsweise als Schubkolbengetriebe ausgebildet, das über eine Pneumatikleitung an eine (nicht dargestellte) Überdruckquelle angeschlossen und definiert ansteuerbar ist.
In the spinning device 3, a sliver 34 placed in a spinning can 28 is spun into a thread 30, which is then wound on the winding device 33 to form a cross-wound bobbin 22.
The winding devices 33 have for this purpose, as known per se, a creel 21 for rotatably supporting the sleeve of a cheese 22, a bobbin drive roller 23, a Fadenchangiereinrichtung 26 and a device 7 for lifting the cross-wound bobbin 22 from the bobbin drive roller 23.
The device 7 is formed, for example, as a thrust piston, which is connected via a pneumatic line to a (not shown) overpressure source and controllable defined.

Im vorliegenden Ausführungsbeispiel erfolgt der Antrieb der Spulenantriebswalze 23 als Gruppenantrieb.
Das heißt, an einer maschinenlangen, maschinenendseitig angetriebenen Antriebswelle sind die Spulenantriebswalzen 23 der einzelnen Arbeitsstellen 2 festgelegt.
In the present embodiment, the drive of the bobbin drive roller 23 takes place as a group drive.
That is, on a machine-length, machine end side driven drive shaft, the bobbin drive rollers 23 of the individual jobs 2 are fixed.

Die Spinnvorrichtung 3 weist im Wesentlichen, wie ebenfalls bekannt, einen Spinnrotor 4, eine Faserbandauflösewalze 12 sowie einen Faserbandeinzugszylinder 14 auf.
Wie in Fig.1 dargestellt, ist der Spinnrotor 4 beispielsweise in einer Stützscheibenlagerung 5 gelagert und wird über einen maschinenlangen Tangentialriemen 6 angetrieben.
Im Ausführungsbeispiel ist auch die Faserbandauflösewalze 12 über einen maschinenlangen Tangentialriemen 13 beaufschlagt, während der Faserbandeinzugszylinder 14 über einen Antrieb 15 einzelmotorisch angetrieben wird.
Der Antrieb 15 des Faserbandeinzugszylinders 14, beispielsweise ein Schrittmotor, ist über eine Steuerleitung 16 an einen Arbeitsstellenrechner 9 angeschlossen.
As is also known, the spinning device 3 essentially has a spinning rotor 4, a sliver-opening roller 12 and a sliver-intake cylinder 14.
As in Fig.1 illustrated, the spinning rotor 4 is mounted for example in a support disk bearing 5 and is driven by a machine-tangential belt 6.
In the embodiment, the sliver picking roller 12 is acted upon by a machine-tangential belt 13, while the sliver feed cylinder 14 is driven by a motor 15 single motor.
The drive 15 of the sliver feed cylinder 14, for example a stepper motor, is connected via a control line 16 to a workstation computer 9.

Des weiteren verfügen die Arbeitsstellen 2 jeweils über eine Fadenabzugseinrichtung 18, mit einem vorzugsweise im Bereich des Antriebes 19 angeordneten Sensor 32, der über eine Steuerleitung 20 mit dem Arbeitsstellenrechner 9 in Verbindung steht.Furthermore, the work stations 2 each have a thread withdrawal device 18, with a preferably arranged in the region of the drive 19 sensor 32, which is connected via a control line 20 to the workstation computer 9 in connection.

In Fadenlaufrichtung gesehen hinter der Fadenabzugseinrichtung 18 ist außerdem eine Fadenspeichereinrichtung 37, vorzugsweise eine pneumatisch beaufschlagbare Speicherdüse, vorgesehen, die über eine Pneumatikleitung 38 an eine (nicht dargestellte) Unterdruckquelle angeschlossen ist.When viewed in the thread running direction behind the thread withdrawal device 18 is also a thread storage device 37, preferably a pneumatically actuable storage nozzle, is provided, which is connected via a pneumatic line 38 to a (not shown) vacuum source.

Unterhalb der Fadenchangiereinrichtung 26 ist schließlich ein Fadenreiniger 11 angeordnet, der den in der Spinnvorrichtung 3 hergestellten Faden 30 auf Fadenfehler hin überwacht, bevor dieser auf die Kreuzspule 22 aufgewickelt wird.
Der Fadenreiniger 11 ist über eine Signalleitung 24 mit dem Arbeitsstellenrechner 9 verbunden.
In den Fadenwächter 11 ist vorzugsweise außerdem eine Signaleinrichtung 17 integriert, die vorzugsweise als LED-Leuchte ausgebildet ist.
Des weiteren ist im Bereich des Spulenrahmens 21 eine Sensoreinrichtung 25 angeordnet, die über eine Signalleitung 31 ebenfalls mit dem Arbeitsstellenrechner 9 in Verbindung steht.
Below the Fadenchangiereinrichtung 26 finally a thread cleaner 11 is arranged, which monitors the thread 30 produced in the spinning device 3 for thread error out before it is wound onto the cheese 22.
The thread cleaner 11 is connected via a signal line 24 to the workstation computer 9.
In the thread monitor 11 also preferably a signaling device 17 is integrated, which is preferably designed as an LED light.
Furthermore, a sensor device 25 is arranged in the region of the coil frame 21, which is also connected to the workstation computer 9 via a signal line 31.

Wie in Fig. 1 angedeutet, ist der Arbeitsstellenrechner 9, der das Betätigungselement der Einrichtung 7 zum Abheben der Kreuzspule, den Antrieb 19 der Fadenabzugseinrichtung 18 sowie den Antrieb 15 des Faserbandeinzugszylinders 14 steuert, über eine Signalleitung 29 außerdem mit einem Schaltelement 27 verbunden.
Das heißt, die Steuereinrichtung 9 kann über das Schaltelement 27 vom Bedienpersonal manuell aktiviert werden.
As in Fig. 1 indicated, the workstation computer 9, which controls the actuating element of the device 7 for lifting the cross-wound bobbin, the drive 19 of the thread take-off device 18 and the drive 15 of the sliver feed cylinder 14, via a signal line 29 also connected to a switching element 27.
That is, the control device 9 can be manually activated by the operating element via the switching element 27.

Ablauf des erfindungsgemäßen Verfahrens:

  • Während des regulären Spinnbetriebs wird in der Spinnvorrichtung 3 aus dem Vorlagefaserband 34 ein Faden 30 gesponnen, der durch die Fadenabzugseinrichtung 18 aus der Spinnvorrichtung 3 gezogen und an die Spulvorrichtung 33 zur Herstellung einer Kreuzspule 22 weiterbefördert wird.
Procedure of the method according to the invention:
  • During the regular spinning operation, a yarn 30 is spun in the spinning device 3 from the original fiber tape 34, which is pulled by the yarn withdrawal device 18 from the spinning device 3 and is conveyed to the winding device 33 for producing a cross-wound bobbin 22.

Der Faden 30 wird auf seinem Weg zur Kreuzspule 22, die durch eine Spulenantriebswalze 23 reibschlüssig angetrieben wird, durch einen elektronischen Fadenreiniger 11 berührungslos abgetastet und dabei auf Fadenfehler hin überprüft.
Bei Auflaufen auf die Kreuzspule wird der Faden 30 außerdem durch eine Fadenchangiereinrichtung 26 traversiert.
Die in der Spinnvorrichtung 3 produzierte und auf die Kreuzspule aufgewickelte Fadenlänge wird mittels eines Sensors 32, der Drehimpulse an der einzelmotorisch angetriebenen Fadenabzugseinrichtung 18 erfasst, ermittelt.
Der Sensor 32 ist, wie vorstehend erwähnt, über eine Signalleitung 20 an den Arbeitsstellenrechner 9 angeschlossen, der aus vorher eingegebenen Garnparametern und den Signalen des Sensors 32 ständig den aktuellen Durchmesser der Kreuzspule 22 berechnet.
Bei Auftreten eines Fadenfehlers, der durch den Fadenreiniger 11 detektiert wird, wird die betreffende Arbeitsstelle 2 durch Abschalten des Antriebes 15 des Faserbandzuführzylinders 14 gestoppt. Außerdem wird anhand der Signale des Sensors 32 der Fadenabzugseinrichtung 18 durch den Arbeitsstellenrechner 9 die Länge des fehlerhaften auf die Kreuzspule 22 aufgelaufenen Fadens 30 ermittelt.
Der Arbeitstellenrechner 9 berechnet außerdem anhand des aktuellen Durchmessers der Kreuzspule 22, um wie viele Winkelgrade die Kreuzspule 22 entgegen ihrer Wickelrichtung rotiert werden muss, um sicherzustellen, dass das fehlerbehaftete Fadenstück wieder von der Kreuzspule 22 abgewickelt ist.
The thread 30 is scanned on its way to the cheese 22, which is frictionally driven by a coil drive roller 23, by an electronic thread cleaner 11 and checked for thread error.
When running on the cheese, the thread 30 is also traversed by a Fadenchangiereinrichtung 26.
The yarn length produced in the spinning device 3 and wound onto the cross-wound bobbin is determined by means of a sensor 32 which detects angular momentum on the single-motor-driven yarn draw-off device 18.
The sensor 32 is, as mentioned above, connected via a signal line 20 to the workstation computer 9, which constantly calculated from previously entered Garnparametern and the signals of the sensor 32, the current diameter of the cheese 22.
When a thread error occurs, which is detected by the thread cleaner 11, the relevant job 2 is stopped by switching off the drive 15 of the sliver feed cylinder 14. In addition, the length of the faulty thread 30 accumulated on the cross-wound bobbin 22 is determined by the workstation computer 9 on the basis of the signals from the sensor 32 of the thread withdrawal device 18.
The workstation computer 9 also calculates, based on the actual diameter of the cross-wound bobbin 22, how many degrees of angle the cross-wound bobbin 22 has to be rotated counter to its winding direction to ensure that faulty thread piece is unwound from the cross-wound bobbin 22 again.

Beim anschließenden, manuellen Rotieren der Kreuzspule 22 in Abwickelrichtung werden die Winkelgrade und die Richtung der Rotation der Kreuzspule 22 durch eine im Bereich der Spulvorrichtung 33 angeordnete Sensoreinrichtung 25 erfasst, deren Hallsensor 35 mit wenigstens einem in einem Hülsenteller des Spulenrahmens 21 angeordneten Permanentmagneten 36 korrespondiert.
Sobald der Arbeitsstellenrechner 9 anhand der von der Sensoreinrichtung 25 übermittelten Signale feststellt, dass die Kreuzspule 22 um ausreichend viele Winkelgrade in Abwickelrichtung rotiert wurde, wird durch den Arbeitsstellenrechner 9 die Signaleinrichtung 17 aktiviert.
Das heißt, das Aufleuchten einer vorzugsweise am Fadenreiniger 11 angeordneten LED-Leuchte zeigt dem Bedienpersonal zuverlässig an, dass die fehlerbehaftete Fadenlänge wieder von der Kreuzspule 22 abgewickelt ist und abgeschnitten werden kann.
During the subsequent manual rotation of the cheese 22 in the unwinding direction, the degrees of angle and the direction of rotation of the cheese 22 are detected by a sensor device 25 arranged in the region of the winding device 33 whose Hall sensor 35 corresponds to at least one permanent magnet 36 arranged in a tube plate of the coil frame 21.
As soon as the workstation computer 9 ascertains, based on the signals transmitted by the sensor device 25, that the cross-wound bobbin 22 has been rotated by a sufficient number of degrees in the unwinding direction, the signal device 17 is activated by the workstation computer 9.
That is, the illumination of a preferably arranged on the thread cleaner 11 LED light reliably indicates to the operator that the faulty thread length is again handled by the cheese 22 and can be cut off.

Nach dem Abschneiden des fehlerhaften Fadenstückes wird das Fadenende, wie üblich, an einer entsprechenden Einrichtung 10 maßgenau abgelängt, vorbereitet und in die Spinnvorrichtung 3 zurückgeführt.
Zum Fortsetzen des Spinnprozesses, das heißt, zum Starten des automatischen Anspinnvorganges, wird anschließend das Schaltelement 27 betätigt, das den Arbeitstellenrechner 9 veranlasst, den Anspinnvorgang zu starten.
After cutting off the faulty thread piece, the thread end, as usual, cut to length on a corresponding device 10, prepared and returned to the spinning device 3.
To continue the spinning process, that is, to start the automatic piecing process, then the switching element 27 is actuated, which causes the workstation computer 9 to start the piecing process.
