Abstract

Die Bildung einer Fadenreservewicklung auf einer Spulenhülse erfolgt an einer Spinnvorrichtung, bei welcher der Faden mittels eines Abzugswalzenpaares kontinuierlich aus der Spinnvorrichtung abgezogen und zur Bildung der Fadenreservewicklung erfaßt und auf die Spulenhülse aufgewunden wird. Erfindungsgemäß wird unmittelbar nach dem Erfassen des Fadens die Spinnspannung zum Aufwinden der Fadenreservewicklung zur Wirkung gebracht und nach dem Aufbringen der Fadenreservewicklung der Faden mit der normalen Aufwindespannung aufgewunden. Der Faden wird auf diese Weise mit einer für eine straffe Wicklung ausreichenden Fadenspannung durch die Spulenhülse abgezogen.The formation of a thread reserve winding on a bobbin tube takes place on a spinning device, in which the thread is continuously drawn out of the spinning device by means of a pair of draw-off rollers and is grasped to form the thread reserve winding and wound onto the bobbin tube. According to the invention, the spinning tension for winding the thread reserve winding is brought into effect immediately after the detection of the thread and the thread is wound up with the normal winding tension after the thread reserve winding has been applied. The thread is drawn off through the bobbin tube with a thread tension sufficient for a tight winding.

Description

Die vorliegende Erfindung betrifft ein Verfahren zum Bilden einer Fadenreservewicklung auf einer Spulenhülse an einer Spinnvorrichtung, bei welcher der mittels eines eine Druckwalze enthaltenden Abzugswalzenpaares kontinuierlich aus der Spinnvorrichtung abgezogene Faden vor Beginn der Fadenreservewicklung in eine Fadensaugeinrichtung gefördert und danach in eine Fadenübergabestellung gebracht wird, in welcher er die Drehebene einer mit der Spulenhülse umlaufenden Fadenfangvorrichtung kreuzt, von letzterer erfaßt und danach abgeschnitten wird.The present invention relates to a method for forming a thread reserve winding on a bobbin tube on a spinning device, in which the thread continuously drawn out of the spinning device by means of a pair of draw roller rollers is conveyed into a thread suction device before the start of the thread reserve winding and then brought into a thread transfer position, in which he crosses the plane of rotation of a thread catching device rotating with the bobbin tube, is grasped by the latter and is then cut off.

Bei der Herstellung von Spulen ist es allgemein üblich, vor Beginn des Spulenaufbaus zunächst am einen Ende der Spulenhülse eine Fadenreserve aufzuwicklen, um später die Fadenenden einzelner voller Spulen miteinander verbinden und so das Garn ohne Unterbrechung von einer Vielzahl von Spulen abziehen zu können. Dabei muß die Fadenreserve so fest auf die Spulenhülse aufgewickelt werden, daß sie sich bei der Handhabung der Spule nicht auflöst bzw. von der Hülse abrutscht und dadurch zu einem Störfaktor wird.In the production of bobbins, it is common practice to first wind up a thread reserve at one end of the bobbin tube before starting the bobbin build-up in order to later connect the thread ends of individual full bobbins to one another and thus to be able to pull the yarn off a large number of bobbins without interruption. The thread reserve must be wound up so tightly on the bobbin tube that it does not dissolve or slide off the tube during handling of the bobbin and thus becomes a disturbing factor.

Die Erfüllung der Forderung nach einer festen Bewicklung der Spulenhülse mit einer Fadenreserve stößt bei einer Spinnvorrichtung, beispielsweise einer Offenend-Spinnvorrichtung, bei der der Faden kontinuierlich abgezogen und der Aufwickelvorrichtung zugeführt wird, jedoch auf Schwierigkeiten. Diese ergeben sich daraus, daß der Faden während der Bildung der Fadenreservewicklung nicht changiert wird und daher die Aufwickelgeschwindigkeit geringer ist als die Geschwindigkeit des von der Spinnvorrichtung nachgelieferten Fadens. Eine für eine feste Aufwicklung der Fadenreserve erforderliche Fadenspannung zwischen der Spulenhülse und dem den Fadenabzug aus der Spinnvorrichtung vornehmenden Abzugswalzenpaar ist damit nicht vorhanden.However, meeting the requirement for a fixed winding of the bobbin tube with a thread reserve encounters difficulties in a spinning device, for example an open-end spinning device, in which the thread is continuously drawn off and fed to the winding device. These result from the fact that the thread is not changed during the formation of the thread reserve winding and therefore the winding speed is lower than the speed of the thread supplied by the spinning device. There is therefore no thread tension required for a tight winding of the thread reserve between the bobbin tube and the pair of take-off rollers which take the thread from the spinning device.

Eine Lösung dieses Problems bei einer Offenend-Spinnspulvorrichtung ist in der EP-OS 0 069 205 aufgezeigt, von der die Erfindung ausgeht. Nach diesem bekannten Vorschlag wird die während der Bildung der Fadenreservewicklung auftretende überschüssige Länge des nachgelieferten Fadens in einem pneumatischen Fadenspeicher zwischengespeichert und mit Beginn des Spulenaufbaus bei der normalen Spulenbewicklung mit Changierung des Fadens über die Hülsenlänge wieder aufgebraucht. Neben dem zusätzlichen Aufwand durch einen pneumati- schen Fadenspeicher und erhöhten Luftverbrauch befriedigt dieses Verfahren jedoch auch hinsichtlich der Straffheit der Fadenreservewicklung nicht.A solution to this problem with an open-end spinning reel device is shown in EP-OS 0 069 205, from which the invention is based. According to this known proposal, the excess length of the subsequent thread that occurs during the formation of the thread reserve winding is temporarily stored in a pneumatic thread memory and is used up again at the beginning of the bobbin build-up in the normal bobbin winding with traversing of the thread over the sleeve length. In addition to the extra effort by a p neumati- rule yarn storage and increased air consumption, however, this method does not satisfy even regarding the tightness of the thread reserve winding.

Aufgabe der vorliegenden Erfindung ist es, ein Verfahren zu schaffen, das die Nachteile des bekannten Vorschlages vermeidet und auf einfache Weise die Bildung einer genügend festen Fadenreservewicklung bei einer Spinnvorrichtung ermöglicht.The object of the present invention is to provide a method which avoids the disadvantages of the known proposal and which in a simple manner enables the formation of a sufficiently firm thread reserve winding in a spinning device.

Diese Aufgabe wird bei einem Verfahren gemäß dem Oberbegriff des Patentanspruchs erfindungsgemäß dadurch gelöst, daß unmittelbar nach dem Erfassen des Fadens die Spinnspannung zum Aufwinden der Fadenreservewindungen zur Wirkung gebracht wird und nach dem Aufbringen der Fadenreservewicklung das Aufwinden des Fadens mit der normalen Aufwindespannung erfolgt.This object is achieved according to the invention in a method according to the preamble of claim that the spinning tension for winding the thread reserve windings is brought into effect immediately after the detection of the thread and the winding of the thread with the normal winding tension takes place after the thread reserve winding has been applied.

Dadurch wird erreicht, daß der Faden während der Bildung der Fadenreservewicklung mit einer für eine straffe Wicklung ausreichenden Fadenspannung durch die Spulenhülse abgezogen wird.It is thereby achieved that the thread is drawn through the bobbin tube with a thread tension sufficient for a tight winding during the formation of the thread reserve winding.

Vorzugsweise wird die Spinnspannung während der Dauer der Fadenreservewicklung dadurch zur Wirkung gebracht, daß die Druckwalze des Abzugswalzenpaares abgehoben wird und nach dem Aufbringen der Fadenreservewicklung auf die Spulenhülse die Druckwalze wieder ihrer Antriebswalze zugestellt wird. Wenn die Druckwalze während des Bildens der Fadenreservewicklung intermittierend abgehoben wird, kann die Fadenspannung und damit die Straffheit der Reservewicklung beeinflußt werden. In weiterer Ausbildung des erfindungsgemäßen Verfahrens wird vorgesehen, daß ein Abschnitt des abgeschnittenen Fadens mit Spinnspannung von den Reservewindungen überwunden wird.The spinning tension is preferably brought into effect during the duration of the thread reserve winding in that the pressure roller of the pair of draw-off rollers is lifted off and the pressure roller is returned to its drive roller after the thread reserve winding has been applied to the bobbin tube. If the pressure roller is lifted intermittently while the thread reserve winding is being formed, the thread tension and thus the tightness of the reserve winding can be influenced. In a further embodiment of the method according to the invention it is provided that a section of the cut thread with spinning tension is overcome by the reserve windings.

Die Erfindung wird nachstehend anhand der beigefügten Zeichnungen näher erläutert. Es zeigt

  • Figur 1 die für die Erläuterung wesentlichen Teile einer Offenend-Spinnvorrichtung mit zugehöriger Aufwickelvorrichtung in perspektivischer Darstellung;
  • Figur 2 einen Abschnitt einer Spulenhülse mit überwundener Fadenreserve.
The invention is explained below with reference to the accompanying drawings. It shows
  • Figure 1 shows the essential parts for the explanation of an open-end spinning device with associated winding device in a perspective view;
  • Figure 2 shows a section of a bobbin with overcome thread reserve.

Die Erfindung ist nicht auf Offenend-Spinnvorrichtungen beschränkt, sondern auch bei anderen Spinnvorrichtungen, aus denen der Faden durch ein Abzugswalzenpaar abgezogen wird, mit Vorteil anwendbar, unabhängig von der Art der Fadenvorlage und der Reservebildung.The invention is not limited to open-end spinning devices, but can also be advantageously used with other spinning devices from which the thread is drawn off by a pair of draw-off rollers, regardless of the type of thread feed and the reserve formation.

Die erfindungsgemäß zum Aufwinden der Fadenreservewindungen benutzte Spinnspannung kann auf verschiedene Weise zur Wirkung gebracht werden, beispielsweise dadurch, daß der Faden nach seinem Erfassen durch die Fadenfangvorrichtung aus der Klemmlinie des Abzugswalzenpaares ausgeworfen wird. Bevorzugt wird jedoch der Faden der Spinnspannung dadurch unterworfen, daß die Druckwalze des Abzugswalzenpaares abgehoben wird.The spinning tension used according to the invention to wind up the thread reserve windings can be brought into effect in various ways, for example by the thread being ejected from the clamping line of the pair of draw-off rollers after it has been gripped by the thread-catching device. However, the thread is preferably subjected to the spinning tension in that the pressure roller of the pair of draw-off rollers is lifted off.

Die nachstehende Beschreibung beschränkt sich auf das Auslegen des Fadens vor der Spulstelle und das Bilden der Fadenreservewicklung. Die diesen Maßnahmen vorausgehenden Verfahrensschritte, wie Anspinnen des von der Spule rückgelieferten Fadens, Abführen des Ansetzers und Wechseln der Spule gegen eine leere Hülse, sind beispielsweise in der EP-OS 0 069 205 beschrieben, so daß es sich erübrigt, hier nochmals darauf einzugehen.The following description is restricted to the laying out of the thread in front of the winding unit and the formation of the thread reserve winding. The process steps preceding these measures, such as spinning on the thread returned from the bobbin, removing the piecing and changing the bobbin for an empty tube, are described, for example, in EP-OS 0 069 205, so that it is not necessary to go into this again here.

In Figur 1 ist mit 1 das Fadenabzugsrohr einer Offenend-Spinnvorrichtung bezeichnet, durch das hindurch der gesponnene Faden F kontinuierlich abgezogen wird. Der Fadenabzug erfolgt durch ein Abzugswalzenpaar, das aus einer Antriebswalze 2 und einer Druckwalze 20 besteht.In FIG. 1, 1 denotes the thread draw-off tube of an open-end spinning device, through which the spun thread F is drawn off continuously. The thread is drawn off by a pair of draw-off rollers, which consists of a drive roller 2 and a pressure roller 20.

Von der Aufwickelvorrichtung ist lediglich eine Spulenhülse 3 mit einem Spulenteller 4 und ihre Antriebswalze 30 gezeigt; die Spulenhülse 3 ist jedoch in bekannter Weise zwischen zwei Spulenarmen drehbar gehalten, die sie gegen die Antriebswalze 30 drücken. Jeder der beiden Spulenarme besitzt zur Aufnahme und Zentrierung der Spulenhülse 3 einen mit der Spulenhülse 3 umlaufenden Spulenteller, von denen der gezeigte Spulenteller 4 mehrere auf seinem Umfang angeordnete und als Fadenfangvorrichtung dienende Schlitze 40 aufweist. Die Schlitze 40 bilden an ihrem Eintritt mit der Umfangstangente des Spulentellers 4 einen spitzen Winkele .From the winding device, only a bobbin 3 with a bobbin 4 and its drive roller 30 is shown; however, the bobbin tube 3 is rotatably held in a known manner between two bobbin arms, which press it against the drive roller 30. Each of the two bobbin arms has a bobbin plate, which rotates with the bobbin tube 3, for receiving and centering the bobbin tube 3, of which the bobbin plate 4 shown has a plurality of slots 40 arranged on its circumference and serving as a thread catching device. At their entry, the slots 40 form an acute angle with the circumferential tangent of the coil plate 4.

Die Handhabung und Führung des Fadens F vor und bei seiner Überführung zur Spulenhülse 3 entspricht den in der EP-OS 0 069 205 beschriebenen Vorgängen. Der dort in Figur 2 gezeigte Fadenführer 5 entspricht der Fadenführungsgabel 5 in Figur 1, die vor der Spulenhülse 3 angeordnet ist. Ein Unterschied besteht lediglich darin, daß die Fadenführungsgabel 5 nicht verschiebbar ist. Ferner entspricht der Mündung 40 der Fadenabsaugvorrichtung 4 in der EP-OS 0 069 205 das mit einer nicht gezeigten Unterdruckquelle verbundene Fadenabsaugrohr 6, das in Nähe seiner Mündung eine Fadenabschneidvorrichtung 60 aufweist. Diese Schneidvorrichtung kann innerhalb des Rohres oder, wie in der EP-OS 0 069 205 gezeigt, auch außerhalb des Rohres angeordnet sein. Da die Fadenführungsgabel 5 ortsfest angeordnet ist, übernimmt ein Fadenauslenker 8 mittels einer Schwenkbewegung die Führung des Fadens zwecks Bildung der Reservewindungen. Ferner ist nahe der Außenseite des Spulentellers 4 ein schwenkbarer Fadenheber 7 vorgesehen. Diese Vorrichtungsteile sind auf einem verfahrbaren Wartungswagen angeordnet und werden entsprechend vor der Aufwickelvorrichtung in Position gebracht, um das Auswechseln einer vollen Spule gegen eine Leerhülse durchzuführen und den aus der Spinnvorrichtung austretenden Faden auf diese Leerhülse zu überführen.The handling and guidance of the thread F before and during its transfer to the bobbin tube 3 corresponds to the processes described in EP-OS 0 069 205. The thread guide 5 shown there in FIG. 2 corresponds to the thread guide fork 5 in FIG. 1, which is arranged in front of the bobbin tube 3. The only difference is that the thread guide fork 5 cannot be moved. Furthermore, the mouth 40 of the thread suction device 4 in EP-OS 0 069 205 corresponds to the thread suction pipe 6 connected to a vacuum source, not shown, which has a thread cutting device 60 in the vicinity of its mouth. This cutting device can be arranged inside the tube or, as shown in EP-OS 0 069 205, also outside the tube. Since the thread guide fork 5 is arranged in a stationary manner, a thread deflector 8 takes over the guiding of the thread by means of a pivoting movement in order to form the reserve windings. Furthermore, a pivotable thread lifter 7 is provided near the outside of the bobbin plate 4. These parts of the device are arranged on a movable maintenance cart and are accordingly before the reel device brought into position to carry out the replacement of a full bobbin for an empty tube and to transfer the thread emerging from the spinning device onto this empty tube.

Nachdem die volle Spule entfernt und eine Leerhülse zum Bewickeln eingelegt worden ist, läuft der von den Abzugswalzen 2, 20 kontinuierlich aus dem Fadenabzugsrohr 1 abgezogene Faden F zunächst in das Fadenabsaugrohr 6, wobei er auf seinem mit gestrichelter Linie gekennzeichneten Weg dorthin in der Fadenführungsgabel 5 geführt ist. Die Fadenführungsgabel 5 befindet sich zu diesem Zeitpunkt in derselben radialen Ebene, in der die Fadenreservewicklung auf den vorgesehenen Teil der Spulenhülse 3 gewickelt werden soll. Anschliessend wird der Fadenheber 7 hochgeschwenkt, so daß der in das Fadenabsaugrohr 6 abgeführte Faden in den Wirkungsbereich der nahe der Ansaugöffnung des Fadenabsaugrohres 6 befindlichen Fadenabschneidvorrichtung 60 gelangt, und gleichzeitig der Fadenauslenker 8 in Richtung zur Spulenhülse 3 und über deren der Reservewicklung vorbehaltenen Abschnitt hinaus verschwenkt. Der zwischen dem Fadenheber 7 und dem Fadenauslenker 8 liegende Fadenabschnitt befindet sich damit in einer Stellung, in der er die Drehebene der Fadenfangschlitze 40 auf dem Umfang des mit der Spulenhülse 3 mitumlaufenden Spulenteller 3 kreuzt und dabei von einem dieser Schlitze eingefangen wird. Unmittelbar danach wird der Faden im Fadenabsaugrohr 6 von der Fadenabschneidvorrichtung 60 durchtrennt und das abgetrennte Fadenende abgesaugt, während das sich zum Spulenteller 4 erstreckende Fadenstück von diesem mitgenommen wird.After the full bobbin has been removed and an empty tube has been inserted for winding, the thread F drawn continuously from the take-off rollers 2, 20 from the thread take-off tube 1 first runs into the thread suction tube 6, where it travels there in the thread guide fork 5 by its broken line is led. The thread guide fork 5 is at this time in the same radial plane in which the thread reserve winding is to be wound on the intended part of the bobbin tube 3. The thread lifter 7 is then swiveled up, so that the thread discharged into the thread suction tube 6 reaches the effective area of the thread cutting device 60 located near the suction opening of the thread suction tube 6, and at the same time the thread deflector 8 pivots in the direction of the bobbin tube 3 and beyond its section reserved for reserve winding . The thread section lying between the thread lifter 7 and the thread deflector 8 is thus in a position in which it crosses the plane of rotation of the thread catching slots 40 on the circumference of the bobbin plate 3 rotating with the bobbin tube 3 and is caught by one of these slots. Immediately thereafter, the thread in the thread suction tube 6 is cut by the thread cutting device 60 and the separated thread end is sucked off, while the piece of thread extending to the bobbin plate 4 is taken away by it.

Sobald der Faden von einem der Fadenfangschlitze 40 erfaßt und damit auf der Hülse 3 festgelegt ist, wird die Druckwalze 20 des Abzugswalzenpaares von der Antriebswalze 2 abgehoben (Abstand a). Das Abzugswalzenpaar ist damit außer Funktion gesetzt und die volle Spinnspannung wirkt auf den Faden, während die umlaufende Spulenhülse 3 selbst den Fadenabzug aus der Spinnvorrichtung übernimmt. Die Spinnspannung, der der Faden beim Abzug durch die Spulenhülse 3 unterworfen ist, bewirkt bei der nun folgenden Bildung der Fadenreservewicklung deren feste Aufwicklung auf der Spulenhülse. Der Fadenabzug durch die Spulenhülse erfolgt während der Dauer des Aufwickelns der Fadenreserve, die vorzugsweise in der Weise auf die Spulenhülse gebracht wird, daß ein Abschnitt des abgeschnittenen Fadens von der Reservewicklung überwunden wird (Figur 2). Dieses Überwinden erfolgt, nachdem der Fadenauslenker 8 kurz nach Beginn der Mitnahme des Fadens durch die Spulenhülse durch Wegschwenken in Richtung zum Spulenteller 4 den Faden freigegeben und die in der radialen Ebene der Fadenreservewicklung angeordnete Fadenführungsgabel 5 die Fadenführung übernommen hat.As soon as the thread is gripped by one of the thread catch slots 40 and is thus fixed on the sleeve 3, the pressure becomes roller 20 of the draw roller pair is lifted from the drive roller 2 (distance a). The pair of take-off rollers is thus deactivated and the full spinning tension acts on the thread, while the rotating bobbin tube 3 itself takes over the thread from the spinning device. The spinning tension to which the thread is subjected when it is drawn off through the bobbin tube 3, when the thread reserve winding is now formed, causes it to be wound up firmly on the bobbin tube. The thread is drawn off through the bobbin tube during the winding up of the thread reserve, which is preferably brought onto the bobbin tube in such a way that a section of the cut thread is overcome by the reserve winding (FIG. 2). This overcoming takes place after the thread deflector 8 has released the thread shortly after the thread has been taken along by the bobbin tube by swiveling away in the direction of the bobbin plate 4 and the thread guide fork 5 arranged in the radial plane of the thread reserve winding has taken over the thread guidance.

Das Einwirken der Spinnspannung wird sofort nach dem Aufbringen der Fadenreservewindungen beendet, zweckmäßig kurz bevor der von der Fadenführungsgabel 5 freigegebene Faden vom Changierfadenführer (nicht gezeigt) der Aufwickelvorrichtung erfaßt wird und die Fadenchangierung für den Spulenaufbau einsetzt. Hierzu wird die Druckwalze 20 des Abzugswalzenpaares wieder in Anlage an die Antriebswalze 2 gebracht, so daß der Abzug des Fadens aus der Spinnvorrichtung durch das Abzugswalzenpaar erfolgt. Der vom Changierfadenführer erfaßte Faden wird nun mit normaler Aufwindespannung auf die Spulenhülse aufgewunden.The action of the spinning tension is ended immediately after the thread reserve turns have been applied, expediently shortly before the thread released by the thread guide fork 5 is gripped by the traversing thread guide (not shown) of the winding device and the thread traversing is used for the bobbin build-up. For this purpose, the pressure roller 20 of the pair of draw-off rollers is brought back into contact with the drive roller 2, so that the thread is drawn off from the spinning device by the pair of draw-off rollers. The thread caught by the traversing thread guide is now wound onto the bobbin tube with normal winding tension.

Die Betätigung der Druckwalze 20 kann grundsätzlich manuell erfolgen. Bei einer vorgesehenen automatischen Wartungsvorrichtung wirkt ein entsprechender Steuermechanismus auf den Hebel 9. Dadurch kann die Druckwalze 20 auch intermittierend abgehoben werden, wobei durch die Häufigkeit der Betätigung des Hebels 9 während der Bildung der Reservewindungen die Fadenspannung beeinflußt werden kann und damit auch die Straffheit der Reservewicklung.The actuation of the pressure roller 20 can basically be done manually. With an automatic maintenance planned direction acts a corresponding control mechanism on the lever 9. As a result, the pressure roller 20 can also be lifted off intermittently, the thread tension can be influenced by the frequency of actuation of the lever 9 during the formation of the reserve windings and thus also the tightness of the reserve winding.
