Description

Technisches GebietTechnical area

Die Erfindung bezieht sich auf ein Verfahren und Vorrichtung zur Herstellung von elastischem Coregarn entsprechend dem Oberbegriff der unabhängigen Ansprüche.The invention relates to a method and device for producing elastic core yarn according to the preamble of the independent claims.

Stand der TechnikState of the art

Bei der Herstellung von Coregarn wird ein Endlosfaden durch Stapelfasern umsponnen. Dadurch können Eigenschaften eines bestimmten Endlosfadens auf ein fertiges Garn übertragen und mit den Eigenschaften der verwendeten Stapelfasern kombiniert werden. Der Endlosfaden dient dabei als Kern des fertigen Garns. Um diesen Kern entsteht in der Folge im Spinnprozess eine Hülle aus Stapelfasern. Auf diese Art und Weise ist es möglich, einen elastischen Baumwollfaden herzustellen. Als Kern wird dazu ein elastischer Endlosfaden, beispielsweise Elastan, verwendet, welcher mit Baumwollfasern umsponnen wird.In the production of core yarn, a continuous thread is spun around with staple fibers. As a result, properties of a certain continuous thread can be transferred to a finished yarn and combined with the properties of the staple fibers used. The continuous thread serves as the core of the finished yarn. A sheath of staple fibers is then created around this core in the spinning process. In this way it is possible to produce an elastic cotton thread. For this purpose, an elastic continuous thread, for example elastane, is used as the core, which is spun with cotton fibers.

Vorrichtungen und Verfahren zur Herstellung von Coregarn sind aus dem Stand der Technik bekannt, beispielsweise offenbart die EP1561845 eine Vorrichtung, bei welcher ein Corefaden einer Faserlunte zugeführt wird, bevor die Faserlunte durch Drehung verfestigt wird. Der Corefaden wird der Faserlunte zugeführt, bevor die Faserlunte das Ausgangswalzenpaar des Streckwerks passiert.Devices and methods for the production of core yarn are known from the prior art, for example disclosed in US Pat EP1561845 a device in which a core thread is fed to a fiber sliver before the fiber sliver is solidified by rotation. The core thread is fed to the fiber sliver before the fiber sliver passes the pair of output rollers of the drafting system.

Einem Streckwerk einer Ringspinnmaschine wird eine Faserlunte bzw. ein Faserverband zugeführt. Beim Durchlaufen des Streckwerks, welches aus mehreren Walzenpaaren besteht, wird der Faserverband durch unterschiedliche Geschwindigkeiten der Walzenpaare verzogen. Dieser verzogene Faserverband verlässt das Streckwerk durch ein Ausgangswalzenpaar. Vor dem Verlassen des Ausgangswalzenpaars wird dem Faserverband ein elastischer Endlosfaden zugeführt. Der Endlosfaden wird dabei von einer Spule abgespult und über ein Lieferwalzenpaar zum Faserverband transportiert. Das Lieferwalzenpaar ist in seiner Umfangsgeschwindigkeit derart auf die Umfangsgeschwindigkeit des Ausgangswalzenpaars abgestimmt, dass der Endlosfaden zwischen dem Lieferwalzenpaar und dem Ausgangswalzenpaar gedehnt wird. In der Folge verlassen der Faserverband und der gedehnte Endlosfaden das Ausgangswalzenpaar und werden über einen Fadenführer zu einem Läufer geführt und über den auf einem Ring umlaufenden Läufer auf eine sich drehende Spule aufgewickelt. Durch die Wirkung von Läufer und Spindel wird der Endlosfaden in den Faserverband eingesponnen und derA fiber sliver or a fiber structure is fed to a drafting system of a ring spinning machine. When passing through the drafting system, which consists of several pairs of rollers, the fiber structure is drawn by the different speeds of the pairs of rollers. This warped fiber structure leaves the drafting system through a pair of output rollers. Before leaving the pair of output rollers, an elastic continuous thread is fed to the fiber structure. The continuous thread is unwound from a bobbin and transported to the fiber structure via a pair of delivery rollers. The peripheral speed of the pair of delivery rollers is matched to the peripheral speed of the pair of output rollers in such a way that the continuous thread is stretched between the pair of delivery rollers and the pair of output rollers. Subsequently abandoned the fiber structure and the stretched continuous thread the output roller pair and are guided to a rotor via a thread guide and wound onto a rotating bobbin via the rotor rotating on a ring. Due to the action of the rotor and spindle, the continuous thread is spun into the fiber structure and the

Faserverband mit dem gedehnten Endlosfaden zu einem elastischen Garn umgebildet.The fiber structure with the stretched continuous thread is transformed into an elastic yarn.

US3243950 offenbart beispielweise ein Verfahren zur Herstellung eines elastischen Coregarns. US3243950 For example, discloses a method for making an elastic core yarn.

Es hat sich nun gezeigt, dass auf Ringspinnmaschinen, bei welchen ein Spulenwechsel automatisch vorgenommen wird, eine zuverlässige Trennung des auf die Spule aufgewickelten Garnes nicht möglich ist, bedingt durch die Elastizität des gesponnen Garns.It has now been shown that on ring spinning machines in which a bobbin change is carried out automatically, a reliable separation of the yarn wound onto the bobbin is not possible due to the elasticity of the spun yarn.

Die automatische Vorrichtung für den Spulenwechsel trennt das Garn dadurch, dass die Spule von der Spindel abgezogen und dabei das Garn über eine Messerkante gezogen wird. Bei einem elastischen Garn wird jedoch das Garn in die Länge gezogen und durch das Messer nicht zuverlässig getrennt. Die führt regelmässig zu Störungen im automatischen Betrieb der Ringspinnmaschine, wobei in Betracht zu ziehen ist, dass an bis zu 2'000 Spinnstellen ein Spulenwechsel gleichzeitig erfolgt.The automatic device for changing the bobbin cuts the yarn by pulling the bobbin off the spindle and pulling the yarn over a knife edge. In the case of an elastic yarn, however, the yarn is drawn in length and is not reliably separated by the knife. This regularly leads to malfunctions in the automatic operation of the ring spinning machine, whereby it should be taken into account that a package change takes place at up to 2,000 spinning positions at the same time.

Darstellung der ErfindungPresentation of the invention

Der Erfindung liegt somit die Aufgabe zugrunde, ein Verfahren sowie eine Vorrichtung dazu bereitzustellen, welche eine störungsfreie Trennung des gesponnen elastischen Garns bei einem Spulenwechsel ermöglichen.The invention is therefore based on the object of providing a method and a device for this purpose, which enable a trouble-free separation of the spun elastic yarn when changing bobbins.

Zur Lösung der Aufgabe wird nunmehr ein Verfahren vorgeschlagen, bei welchem beim Abspinnen einer vollen Spule ein Umfangsgeschwindigkeitsverhältnis zwischen dem Ausgangswalzenpaar und dem Lieferwalzenpaar derart angepasst wird, dass die Dehnung des Endlosfadens reduziert wird.To solve the problem, a method is now proposed in which, when a full bobbin is spun, a circumferential speed ratio between the pair of output rollers and the pair of delivery rollers is adapted in such a way that the elongation of the continuous thread is reduced.

Die Umfangsgeschwindigkeit des Lieferwalzenpaares bestimmt die Geschwindigkeit, mit welcher das elastische Filament von der Spule abgespult wird. Die Umfangsgeschwindigkeit des Ausgangswalzenpaares des Streckwerks bestimmt, mit welcher Geschwindigkeit der Faserverband zusammen mit dem elastischen Endlosfaden an die Spinneinrichtung weitergegeben wird. Das Verhältnis zwischen diesen beiden Geschwindigkeiten ist im Betriebsfall auf das verwendete Material des Endlosfadens abgestimmt. Bei Verwendung eines elastischen Endlosfadens ist die Umfangsgeschwindigkeit des Auslaufwalzenpaares höher als die Umfangsgeschwindigkeit des Lieferwalzenpaares und damit das genannte Verhältnis erheblich grösser als 1. Die Grösse des Verhältnisses bestimmt die Dehnung des Endlosfadens, mit welcher dieser das Ausgangswalzenpaar verlässt.The peripheral speed of the pair of delivery rollers determines the speed at which the elastic filament is unwound from the spool. The peripheral speed of the pair of output rollers of the drafting device determines the speed at which the fiber structure is passed on to the spinning device together with the elastic continuous thread. The ratio between these two speeds is matched to the material of the continuous thread used during operation. When using an elastic continuous thread, the peripheral speed is of the pair of outlet rollers is higher than the peripheral speed of the pair of delivery rollers and thus the ratio mentioned is significantly greater than 1. The size of the ratio determines the elongation of the continuous thread with which it leaves the pair of outlet rollers.

Wird nun das Umfangsgeschwindigkeitsverhältnis zwischen dem Ausgangswalzenpaar und dem Lieferwalzenpaar beim Abspinnen reduziert, wird der Endlosfaden mit weniger Dehnung an die Spinneinrichtung weitergegeben. Entsprechend ist das fertige Coregarn ebenfalls weniger elastisch, da die um das Endlosgarn herumgesponnenen Fasern selbst keine Dehnung ermöglichen. Das Coregarn kann nur soweit gedehnt werden, bis der Zustand wieder erreicht ist, bei welchem der Faserverband mit dem Endlosfaden die Spinneinrichtung durchlaufen hat. Dadurch ergibt sich ein besseres Trennverhalten beim Abziehen des Coregarns über eine Messerklinge beim automatischen Spulenwechsel.If the circumferential speed ratio between the pair of output rollers and the pair of delivery rollers is now reduced during spinning, the continuous thread is passed on to the spinning device with less elongation. Correspondingly, the finished core yarn is also less elastic, since the fibers spun around the continuous yarn themselves do not allow any elongation. The core yarn can only be stretched until the state is reached again in which the fiber structure with the continuous thread has passed through the spinning device. This results in better separating behavior when the core yarn is drawn off using a knife blade during automatic bobbin change.

In einer vorteilhaften Ausführung wird beim Abspinnen das Umfangsgeschwindigkeitsverhältnis zwischen dem Ausgangswalzenpaar und dem Lieferwalzenpaar auf unter 3, vorzugsweise auf zwischen 1 bis 2.5, weiter vorzugsweise auf zwischen 1 bis 1.5 reduziert. Besonders vorteilhaft ist es, wenn beim Abspinnen das Umfangsgeschwindigkeitsverhältnis zwischen dem Ausgangswalzenpaar und dem Lieferwalzenpaar auf eins reduziert wird. Dies bedeutet, dass durch die Spinneinrichtung ein Coregarn hergestellt wird, welches trotz der Verwendung eines elastischen Endlosfadens als Kern in seinen Eigenschaften einem Garn entspricht, das ohne einen elastischen Endlosfaden hergestellt würde. Auf diese Art können für die Trennung des gesponnen Fadens bei einem automatischen Spulenwechsel die gleichen technischen Einrichtung verwendet werden, wie bei einem Stapelfasergarn, welches ohne Zuführung eines elastischen Kerns hergestellt wurde. Da die zu einem Garn umgebildeten Stapelfasern eine stark eingeschränkte Elastizität aufweisen, reisst das Garn schon bei kleinsten Dehnungen. Auf dieses Verhalten hat ein elastischer Kern keinen Einfluss, wenn dieser nicht in einem gedehnten Zustand umsponnen wurde.In an advantageous embodiment, the circumferential speed ratio between the pair of output rollers and the pair of delivery rollers is reduced to below 3, preferably to between 1 to 2.5, more preferably to between 1 to 1.5, during spinning. It is particularly advantageous if the circumferential speed ratio between the pair of output rollers and the pair of delivery rollers is reduced to one during spinning. This means that the spinning device produces a core yarn which, despite the use of an elastic continuous thread as the core, corresponds in its properties to a yarn which would be produced without an elastic continuous thread. In this way, the same technical equipment can be used for the separation of the spun thread during an automatic bobbin change as with a staple fiber yarn which was produced without feeding an elastic core. Since the staple fibers transformed into a yarn have a very limited elasticity, the yarn breaks even with the slightest stretch. An elastic core has no influence on this behavior if it is not wound in a stretched state.

Ebenfalls ist eine Vorrichtung zur Herstellung eines elastischen Coregarns mit einem Streckwerk zum Verziehen eines Faserverbandes vorgesehen, wobei das Streckwerk ein Ausgangswalzenpaar aufweist, und ein Lieferwalzenpaar zur Zuführung eines elastischen Endlosfadens zum Ausgangswalzenpaar vorgesehen ist. Zur Einbindung des elastischen Endlosfadens in den Faserverband ist eine Ringspinnvorrichtung vorgesehen, wobei ein Umlaufgeschwindigkeitsverhältnis zwischen dem Ausgangswalzenpaar und dem Lieferwalzenpaar beim Abspinnen reduziert ist.A device is also provided for producing an elastic core yarn with a drafting device for drawing a fiber structure, the drafting device having a pair of output rollers and a pair of delivery rollers for feeding an elastic one Endless thread is provided to the output roller pair. A ring spinning device is provided for integrating the elastic continuous thread into the fiber structure, with a rotational speed ratio between the pair of output rollers and the pair of delivery rollers being reduced during spinning.

In einer vorteilhaften Ausführung ist beim Abspinnen das Umfangsgeschwindigkeitsverhältnis zwischen dem Ausgangswalzenpaar und dem Lieferwalzenpaar auf unter 3, vorzugsweise auf zwischen 1 bis 2.5, weiter vorzugsweise auf zwischen 1 bis 1.5 reduziert. Besonders vorteilhaft ist es, wenn beim Abspinnen das Umfangsgeschwindigkeitsverhältnis zwischen dem Ausgangswalzenpaar und dem Lieferwalzenpaar auf eins reduziert ist.In an advantageous embodiment, the circumferential speed ratio between the pair of output rollers and the pair of delivery rollers is reduced to below 3, preferably to between 1 to 2.5, more preferably to between 1 to 1.5, during spinning. It is particularly advantageous if the circumferential speed ratio between the output roller pair and the delivery roller pair is reduced to one during spinning.

Die beiden Umfangsgeschwindigkeiten sind vorteilhaft mit einer elektronischen oder mechanischen Kopplung versehen. Es ist in einer vorteilhaften Ausführung eine Steuerung vorgesehen, welche es ermöglicht, die Umfangsgeschwindigkeit des Lieferwalzenpaares an eine sich beim Abspinnen verändernde Umfangsgeschwindigkeit des Ausgangswalzenpaares anzupassen. Es ist jedoch auch denkbar, dass die Antriebe des Lieferwalzenpaares und des Ausgangswalzenpaares mechanisch verbunden sind und beim Abspinnen in dieser Verbindung eine Umschaltung erfolgen kann, um das Umfangsgeschwindigkeitsverhältnis zu reduzieren.The two peripheral speeds are advantageously provided with an electronic or mechanical coupling. In an advantageous embodiment, a control is provided which makes it possible to adapt the circumferential speed of the delivery roller pair to a circumferential speed of the output roller pair that changes during spinning. However, it is also conceivable that the drives of the delivery roller pair and the output roller pair are mechanically connected and a switchover can take place in this connection during spinning in order to reduce the circumferential speed ratio.

Kurze Beschreibung der FigurBrief description of the figure

Im Weiteren wird die Erfindung anhand von der einzigen Figur näher erläutert. Diese zeigt in einer schematischen Darstellung eine Spinnstelle zur Herstellung von elastischem Coregarn. Es werden nur die für die Erfindung wichtigen Elemente gezeigt.The invention is explained in more detail below with reference to the single figure. This shows in a schematic representation a spinning station for the production of elastic core yarn. Only the elements important to the invention are shown.

Wege zur Ausführung der ErfindungWays of Carrying Out the Invention

In der einzigen Figur ist eine Spinnstelle einer Ringspinnmaschine gezeigt. Die Spinnstelle umfasst ein Streckwerk 1 mit einem Ausgangswalzenpaar 3. Das Streckwerk 1 ist beispielhaft mit einem Eingangswalzenpaar 13 und einem mit jeweils einem Riemchen 15 umschlungenen Mittelwalzenpaar 14. Der in das Streckwerk 1 einlaufende Faserverband 2 wird bedingt durch die unterschiedlichen Drehzahlen der Walzenpaare beim Durchlaufen des Streckwerks 1 verzogen. Vor dem Ausgangswalzenpaar 3 wird dem Faserverband 2 ein elastischer Endlosfaden 8 zugeführt. Die Zuführung erfolgt über ein Lieferwalzenpaar 9, welches den Endlosfaden 8 von einer Vorratsspule 10 abspult. Der Faserverband 2 und der Endlosfaden 8 werden über einen Fadenführer 4 zu einem Läufer 5 geführt. Der Läufer 4 rotiert auf einem Ring 6 um eine sich drehende Spule 7. Durch die Drehbewegungen von Läufer 4 und Spule 7 wird der Faserverband 2 zusammen mit dem Endlosfaden 8 zu einem fertigen Coregarn umgebildet und gleichzeitig auf der Spule 7 aufgewickelt. Der Ring 6 ist auf einer Ringbank 11 befestigt, welche sich entlang der Spulenachse 12 hin und her respektive auf und ab bewegt, was sich in einer gleichmässigen Aufwicklung des Coregarns auf der Spule 7 auswirkt.In the single figure, a spinning station of a ring spinning machine is shown. The spinning station comprises a drafting device 1 with an output roller pair 3. The drafting device 1 is exemplarily with an input roller pair 13 and a middle roller pair 14 each wrapped with a strap 15 Drafting system 1 warped. Before the output roller pair 3 is the Fiber structure 2 is supplied with an elastic continuous thread 8. The supply takes place via a delivery roller pair 9, which unwinds the continuous thread 8 from a supply spool 10. The fiber structure 2 and the continuous thread 8 are guided to a traveler 5 via a thread guide 4. The rotor 4 rotates on a ring 6 around a rotating bobbin 7. As a result of the rotary movements of the rotor 4 and bobbin 7, the fiber structure 2 together with the continuous thread 8 is converted into a finished core yarn and is simultaneously wound onto the bobbin 7. The ring 6 is attached to a ring rail 11, which moves back and forth or up and down along the bobbin axis 12, which results in an even winding of the core yarn on the bobbin 7.

Die Umgangsgeschwindigkeit des Lieferwalzenpaares 9 steht in einem bestimmten Verhältnis zur Umfangsgeschwindigkeit des Ausgangswalzenpaares 3, welches im Betrieb durch das verwendete Material des Endlosfadens 8 bestimmt wird.The circumferential speed of the pair of delivery rollers 9 is related to the circumferential speed of the pair of output rollers 3, which is determined by the material of the continuous thread 8 used during operation.

In einer vorteilhaften Ausführung wird beim Abspinnen das Umfangsgeschwindigkeitsverhältnis zwischen dem Ausgangswalzenpaar 3 und dem Lieferwalzenpaar 9 auf unter 3, vorzugsweise auf zwischen 1 bis 2.5, weiter vorzugsweise auf zwischen 1 bis 1.5 reduziert. Besonders vorteilhaft ist es, wenn beim Abspinnen das Umfangsgeschwindigkeitsverhältnis zwischen dem Ausgangswalzenpaar und dem Lieferwalzenpaar auf eins reduziert wird. Dies bedeutet, dass durch die Spinneinrichtung ein Coregarn hergestellt wird, welches trotz der Verwendung eines elastischen Endlosfadens als Kern in seinen Eigenschaften einem Garn entspricht, das ohne einen elastischen Endlosfaden hergestellt würde. Auf diese Art können für die Trennung des gesponnen Fadens bei einem automatischen Spulenwechsel die gleiche technische Einrichtung verwendet werden, wie bei einem Stapelfasergarn, welches ohne Zuführung eines elastischen Kerns hergestellt wurde. Da die zu einem Garn umgebildeten Stapelfasern eine stark eingeschränkte Elastizität aufweisen, reisst das Garn schon bei kleinsten Dehnungen. Auf dieses Verhalten hat ein elastischer Kern keinen Einfluss, wenn dieser nicht in einem gedehnten Zustand umsponnen wurde.In an advantageous embodiment, the circumferential speed ratio between the pair of output rollers 3 and the pair of delivery rollers 9 is reduced to below 3, preferably to between 1 to 2.5, more preferably to between 1 to 1.5, during spinning. It is particularly advantageous if the circumferential speed ratio between the pair of output rollers and the pair of delivery rollers is reduced to one during spinning. This means that the spinning device produces a core yarn which, despite the use of an elastic continuous thread as the core, corresponds in its properties to a yarn which would be produced without an elastic continuous thread. In this way, the same technical device can be used for the separation of the spun thread during an automatic bobbin change as in the case of a staple fiber yarn which was produced without feeding an elastic core. Since the staple fibers transformed into a yarn have a very limited elasticity, the yarn breaks even with the slightest stretch. An elastic core has no influence on this behavior if it is not wound in a stretched state.

Die beiden Umfangsgeschwindigkeiten sind mit einer Kopplung 16 versehen. Dies kann elektronisch oder mechanisch ausgeführt sein. Es ist in einer vorteilhaften Ausführung eine Steuerung vorgesehen, welche es ermöglicht, die Umfangsgeschwindigkeit des Lieferwalzenpaares an eine sich beim Abspinnen verändernde Umfangsgeschwindigkeit des Ausgangswalzenpaares anzupassen. Es ist jedoch auch denkbar, dass die Antriebe des Lieferwalzenpaares und des Ausgangswalzenpaares verbunden sind und beim Abspinnen in dieser Verbindung eine Umschaltung erfolgen kann, um das Umfangsgeschwindigkeitsverhältnis zu reduzieren.The two peripheral speeds are provided with a coupling 16. This can be done electronically or mechanically. In an advantageous embodiment, a control is provided which makes it possible to adjust the circumferential speed of the delivery roller pair to a circumferential speed which changes during spinning of the pair of output rollers. However, it is also conceivable that the drives of the delivery roller pair and the output roller pair are connected and a changeover can take place in this connection during spinning in order to reduce the circumferential speed ratio.
