Description

Technisches GebietTechnical field

Die Erfindung betrifft eine Vorrichtung zur Erzeugung eines Garnes mit zufällig angeordneten und/oder ausgebildeten Effekten, enthaltend

  • (a) Kopmittel, die um eine Drehachse drehbar sind zum Aufwickeln des Garnes auf einen Wickelkörper (16) und Kopantriebsmittel (18) zum Antreiben der Kopmittel um diese Drehachse,
  • (b) erste Fadenführungsmittel (12), die auf der besagten Drehachse der Kopmittel angeordnet sind zum Führen von Grundfäden (10), wobei diese Grundfäden durch die Drehung der Kopmittel zur Bildung eines Garnes verzwirnt und auf den besagten Wickelkörper (16) aufgewickelt werden.
The invention relates to a device for producing a yarn with randomly arranged and / or designed effects, containing
  • (a) copying means which are rotatable about an axis of rotation for winding the yarn onto a winding body (16) and cop driving means (18) for driving the copying means about this axis of rotation,
  • (b) first thread guide means (12) which are arranged on said axis of rotation of the copying means for guiding base threads (10), these base threads being twisted by the rotation of the copying means to form a yarn and being wound onto said winding body (16).

Zugrundeliegender Stand der TechnikUnderlying state of the art

Garne bestehen aus Grundfäden, die durch eine Drehbewegung umeinandergedreht und dadurch verzwirnt werden. Dazu verwendet man Vorrichtungen, bei denen die Grundfäden durch eine zentrale Fadenführung zugeführt werden und dann auf einen schnell umlaufenden Wickelkörper, den Kop, aufgewickelt werden. Die Fadenführung sitzt etwa auf der Umlaufachse des Kops. Bei dem Aufwickelvorgang beschreiben die Grundfäden eine konische Fläche und werden dabei miteinander verzwirnt. Das ist eine normale Verzwirneinrichtung.Yarns consist of basic threads that are twisted around each other by a twisting movement and thereby twisted. For this purpose, devices are used in which the basic threads are fed through a central thread guide and are then wound onto a rapidly rotating winding body, the cop. The thread guide sits approximately on the axis of the cop. During the winding process, the basic threads describe a conical surface and are twisted together. This is a normal twisting device.

Es ist häufig erwünscht, Garne mit bestimmten Unregelmäßigkeiten wie Noppen oder Knoten zu versehen. Man bezeichnet diese Unregelmäßigkeiten als "Effekte". Durch solche Effekte wird bei dem fertigen Gewebe oder Gewirke eine bestimmte, gewünschte optische Wirkung erzielt. Es ist dabei wesentlich, daß die Effekte in zufälliger Folge auftreten und keine Periodizität erhalten wird. In einem solchen Falle würden sich nämlich beim Verweben eines solchen Garnes unerwünschte Muster ("Bilderung") ergeben.It is often desirable to provide certain irregularities such as knobs or knots on yarns. These irregularities are called "effects". Such effects achieve a specific, desired optical effect in the finished woven or knitted fabric. It is essential that the effects occur in a random sequence and that no periodicity is obtained. In such a case, undesirable patterns (“formation”) would result when such a yarn was woven.

Durch die US-A 3 805 344 ist eine Texturiervorrichtung bekannt, welche zur Erzeugung unregelmäßiger Effekte ein Faden in zeitlicher Aufeinanderfolge mit unterschiedlichen Geschwindigkeiten zugeführt wird.A texturing device is known from US Pat. No. 3,805,344 which is fed with a thread in chronological succession at different speeds in order to produce irregular effects.

Die GB-A 2 122 229 zeigt eine Vorrichtung, bei welcher ein schon verzwirntes Kerngarn von Rollen einer Falschdrallvorrichtung zugeführt wird. Das Effektgarn wird seitlich mit größerer Geschwindigkeit als das Kerngarn zugeführt und wird längs des Kerngarnes auf- und abbewegt. Durch Vergrößerung des Dralls des Garnes in der Falschdrallvorrichtung werden die so erzeugten Beulen und das Kerngarn miteinander verbunden, so daß kein anschließender Heizprozess erforderlich ist.GB-A 2 122 229 shows a device in which an already twisted core yarn from rolls is fed to a false twist device. The fancy yarn is fed laterally at a higher speed than the core yarn and is moved up and down along the core yarn. By increasing the twist of the yarn in the false twist device, the dents produced in this way and the core yarn are connected to one another, so that no subsequent heating process is required.

Somit verwendet die GB-A 2 122 229 eine Falschdrallvorrichtung zur Vergrößerung des Dralls von schon verzwirntem Material.GB-A 2 122 229 thus uses a false twist device to increase the twist of already twisted material.

Die EP-A 0 177 009 arbeitet nach dem gleichen Prinzip wie die oben diskutierte GB-A 2 122 229. Es gibt dort Kern- und Mantelkomponenten. Das Noppengarn bildet den Noppen, indem es eine mehrlagige Wicklungsstruktur liefert. Das geschieht durch Uberliefern der Mantelkomponente senkrecht zu der Kernkomponente in einer Drallzone einer Falschdrall-Texturiermaschine.EP-A 0 177 009 works on the same principle as GB-A 2 122 229 discussed above. There are core and shell components. The pimple yarn forms the pimple by providing a multi-layer winding structure. This is done by delivering the jacket component perpendicular to the core component in a swirl zone of a false twist texturing machine.

Die DE-A 2 616 786 betrifft ebenfalls eine Vorrichtung mit einer Falschdrallstrecke. Auf dieser Falschdrallstrecke wird ein Effektgarn mit einer bewegten Zufuhreinrichtung auf einen Grundfaden aufgebracht. Im Prinzip entspricht diese Anordnung der schon diskutierten EP-A 0 177 009. Dabei sind Grundfäden und Effektfäden von Multifilamentfäden gebildet.DE-A 2 616 786 also relates to a device with a false twist section. A fancy yarn with a moving feeding device is applied to a basic thread on this false twist path. In principle, this arrangement corresponds to the already discussed EP-A 0 177 009. Basic threads and effect threads are formed from multifilament threads.

Auch bei der FR-A 2 315 554 durchläuft der multifile Grundfaden eine Falschdralleinrichtung. Ein Effektfaden wird von einer Fadenführung seitlich zugeführt und wickelt sich um den Kern- oder Grundfaden.With FR-A 2 315 554, too, the multifilament basic thread runs through a false twist device. An effect thread is fed laterally from a thread guide and wraps around the core or base thread.

Der Erfindung liegt die Aufgabe zugrunde, bei einem Garn, das durch Verzwirnung mehrerer Fäden hergestellt wird, Effekte der beschriebenen Art in einem Arbeitsgang mit der Verzwirnung anzubringen.The invention is based, to apply effects of the type described in one operation with the twisting in a yarn which is produced by twisting a plurality of threads.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, durch

  • (c) zweite Fadenführungsmittel, die von Haltemitteln gehalten und zwischen den ersten Fadenführungsmitteln und den Kopmitteln angeordnet und längs der Grundfäden beweglich sind, wobei die besagten Grundfäden durch die besagten zweiten Fadenführungsmittel geführt sind,
  • (d) Mittel zum Zuführen eines Effektgarnfadens,
  • (e) Mittel zum Führen des Effektgarnfadens durch die besagten zweiten Fadenführungsmittel zum Verzwirnen mit den Grundfäden infolge der Drehung der Kopmittel,
  • (f) Antriebsmittel zum Hin- und Herbewegen der Haltemittel im wesentlichen längs der Grundfäden und
  • (g) Steuermittel zum Steuern der Antriebsmittel, wobei die Steuermittel Zufallsgeneratormittel enthalten, wodurch die hin- und hergehende Bewegung der Haltemittel zufällig erfolgt.
According to the invention, this object is achieved by
  • (c) second thread guide means, which are held by holding means and are arranged between the first thread guide means and the coping means and are movable along the base threads, said base threads being guided through said second thread guide means,
  • (d) means for feeding fancy yarn,
  • (e) means for guiding the fancy thread through said second thread guiding means for twisting with the base threads due to the rotation of the head means,
  • (f) drive means for reciprocating the holding means substantially along the main threads and
  • (g) control means for controlling the drive means, the control means including random generator means whereby the reciprocating movement of the holding means is random.

Bei der erfindungsgemäßen Vorrichtung wird der Effektfaden der Verzwirnungseinrichtung quer zur Laufrichtung der zu verzwirnenden "Grundfäden" zugeführt und durch die Verzwirnungseinrichtung mit diesen verzwirnt. Wenn der Effekthebel stillsteht und der Effektfaden mit der gleichen Zuführgeschwindigkeit zugeführt wird wie die Grundfäden, dann wird der Effektfaden ganz normal mit den Grundfäden verzwirnt. Wenn aber der Effekthebel beispielsweise mit einer solchen Geschwindigkeit längs der zu verzwirnenden Grundfäden bewegt würde, daß der Punkt, in welchem der Effektfaden zugeführt wird, sich mit der Zuführgeschwindigkeit der Grundfäden bewegt, dann wird der Effektfaden praktisch nur an einer Stelle des Garnes "aufgewickelt", es entsteht ein kleiner Knoten. Zwischen diesen Extremen liegen die Fälle, in denen der Punkt, in welchem der Effektfaden zugeführt wird, sich langsamer bewegt als die Grundfäden, so daß ein sich über eine bestimmte Länge erstreckender Effekt entsteht. Die Parameter der Bewegung des Effekthebels und die Zeitpunkte dieser Bewegung werden über die elektronische Steuereinheit von einem Zufallsgenerator gesteuert.In the device according to the invention, the effect thread is fed to the twisting device transversely to the running direction of the "basic threads" to be twisted and twisted with it by the twisting device. If the effect lever is at a standstill and the effect thread is fed at the same feed speed as the basic threads, then the effect thread is twisted in the normal way with the basic threads. However, if, for example, the effect lever were moved along the basic threads to be twisted at such a speed that the point at which the effect thread is fed moves at the feed speed of the basic threads, then the effect thread is practically "wound up" only at one point of the yarn. , a small knot is created. Between these extremes are the cases in which the point at which the effect thread is fed moves more slowly than the base threads, so that there is an effect that extends over a certain length. The parameters of the movement of the effect lever and the times of this movement are controlled by a random generator via the electronic control unit.

Es werden also unterschiedliche Effekte erzeugt. Diese Effekte sind nach Form und Anordnung innerhalb vorgebbarer Grenzen zufällig. Die Erzeugung der Effekte ist mit der Verzwirnung des Garnes kombiniert. Die Vorrichtung nach der Erfindung läßt sich ohne Schwierigkeiten an vorhandene Verzwirnungseinrichtungen anbauen.Different effects are created. These effects are random in form and arrangement within predefined limits. The effects are combined with the twisting of the yarn. The device according to the invention can be easily attached to existing twisting devices.

Bevorzugte Ausführung der ErfindungPreferred embodiment of the invention

In Fig.1 sind mit 10 Grundfäden bezeichnet, die zu einem Garn verzwirnt werden sollen. Die Grundfäden 10 sind durch eine obere, zentrale Fadenführung 12 geführt. Die Grundfäden 10 werden mit einer Durchlaufgeschwindigkeit V1 von etwa 7 bis 40 m/min zugeführt. Die Grundfäden 10 werden durch eine untere Fadenführung 14 auf einen Kops 16 geführt. Das ist ein kegelstumpfförmiger Wickelkörper, der von einem Kopsantrieb 18 mit etwa 2500 bis 5000 Umdrehungen pro Minute angetrieben wird. Die obere Fadenführung 12 liegt etwa auf der Umlaufachse des Kops 16. Die Grundfäden 10 beschreiben dadurch eine kegelförmige Fläche und werden umeinandergedreht und miteinander verzwirnt. Das ist eine übliche Verzwirnungseinrichtung.In FIG. 1 there are 10 basic threads which are to be twisted into a yarn. The basic threads 10 are guided through an upper, central thread guide 12. The basic threads 10 are fed at a throughput speed V1 of approximately 7 to 40 m / min. The basic threads 10 are guided through a lower thread guide 14 onto a cop 16. This is a truncated cone-shaped winding body which is driven by a cop drive 18 at about 2500 to 5000 revolutions per minute. The upper thread guide 12 lies approximately on the axis of rotation of the cop 16. The base threads 10 thereby describe a conical surface and are twisted around one another and twisted together. This is a common twisting device.

Es werden nun Effektfäden 20 und 22 durch einen Zuführantrieb 24 mit einer Zuführgeschwindigkeit V2 zugeführt. Der Zuführantrieb ist hier durch zwei Rollen 25 und 26 dargestellt. Die Rolle 26 wird durch einen Antriebsmotor 28 angetrieben. Die Effektfäden 20 und 22 werden über je einen Effekthebel 30 bzw. 32 quer zur Laufrichtung der Grundfäden 10 zugeführt und mit diesen verzwirnt. Diese Effekthebel 30 und 32 sind durch einen Effekthebelantrieb 34 auslenkbar, wie durch den Doppelpfeil 26 in Fig.1 angedeutet ist. Dadurch können die Punkte 38 und 40, in denen die Effektfäden 20 bzw. 22 den zu verzwirnenden Grundfäden 10 zugeführt werden, längs der Laufrichtung dieser Grundfäden 10 verlagert werden. Wenn der Effekthebel 30 stillsteht und die Zuführgeschwindigkeit vz gleich der Durchlaufgeschwindigkeit vi ist, dann wird der Effektfaden 20 ganz normal mit den Grundfäden 10 verzwirnt. Wird der Effekthebel 30 durch den Effekthebelantrieb 34 mit einer solchen Winkelgeschwindigkeit im Uhrzeigersinn verschwenkt, daß sich der Punkt 38 mit der Durchlaufgeschwindigkeit V1 von oben nach unten verläuft, dann läuft der Punkt 38 mit den Grundfäden 10 mit. Der Effektfaden 20 wird stets an der gleichen Stelle der Grundfäden 10 und des daraus verzwirnten Garnes zugeführt und auf die Grundfäden 10 aufgewickelt. Es entsteht dann an dieser Stelle ein sehr konzentrierter Knoten. Wenn sich der Punkt 38 mit einer geringeren Geschwindigkeit als der Durchlaufgeschwindigkeit bewegt, dann wird auf einem endlichen Abschnitt eine größere Länge von Effektfaden pro Längeneinheit des Garnes zugeführt als von den Grundfäden. Der Effektfaden 20 bildet dann einen mehr oder weniger langgestreckten Effekt. Entsprechend wirkt der Effektfaden 22 mit dem Effekthebel 32.Effect threads 20 and 22 are now fed by a feed drive 24 at a feed speed V2 . The feed drive is represented here by two rollers 25 and 26. The roller 26 is driven by a drive motor 28. The effect threads 20 and 22 are each fed via an effect lever 30 or 32 transversely to the running direction of the base threads 10 and twisted with them. These effect levers 30 and 32 can be deflected by an effect lever drive 34, as indicated by the double arrow 26 in FIG. 1. As a result, the points 38 and 40, in which the effect threads 20 and 22 are fed to the base threads 10 to be twisted, can be shifted along the running direction of these base threads 10. If the effect lever 30 is stationary and the feed speed v z is equal to the throughput speed v i , then the effect thread 20 is twisted with the basic threads 10 in the normal way. If the effect lever 30 is pivoted clockwise by the effect lever drive 34 at such an angular speed that the point 38 runs from top to bottom at the throughput speed V1 , then the point 38 runs along with the basic threads 10. The effect thread 20 is always fed to the base thread 10 and the yarn twisted therefrom at the same point and wound onto the base thread 10. This creates a very concentrated knot at this point. If the point 38 moves at a lower speed than the throughput speed, then a greater length of fancy threads per unit length of yarn is fed on a finite section than from the basic threads. The effect thread 20 then forms a more or less elongated effect. The effect thread 22 acts accordingly with the effect lever 32.

Wenn an den Effekthebeln eine Fadenführung fest angebracht wäre, durch welche die Effektfäden hindurchgeführt sind, können sich Probleme dadurch ergeben, daß der Effekthebel eine Schwenkbewegung ausführt. Wie aus Fig.2 ersichtlich ist, weist der Effekthebel 30 einen in Längsrichtung verlaufenden Schlitz 42 auf. In dem Schlitz 42 ist eine hülsenförmige Fadenführung 44 mittels einer Umfangsnut 46 verschiebbar geführt. Durch die Fadenführung 44 sind die schon verzwirnten Grundfäden 10 von oben nach unten hindurchgeführt. Durch einen seitlichen Schlitz 48 ist der Effektfaden 20 zugeführt. Der Effektfaden 20 wird bei der Drehbewegung des Kops 16 mit den Grundfäden 10 verzwirnt oder um diese herumgewickelt.If a thread guide were firmly attached to the effect levers, through which the effect threads are passed, problems can arise if the effect lever carries out a pivoting movement. As can be seen from FIG. 2, the effect lever 30 has a slot 42 running in the longitudinal direction. A sleeve-shaped thread guide 44 is slidably guided in the slot 42 by means of a circumferential groove 46. The already twisted base threads 10 are passed through the thread guide 44 from top to bottom. The effect thread 20 is fed through a side slot 48. The effect thread 20 is twisted or wound around the base threads 10 during the rotational movement of the cop 16.

Der Effekthebelantrieb 34 und der Zuführantrieb 24 sind von einer elektronischen Steuereinheit 50 gesteuert. Die elektronische Steuereinheit 50 enthält einen Zufallsgenerator. Die Steuereinheit 50 steuert demgemäß die Zuführgeschwindigkeit wie die Winkelgeschwindigkeit der Effekthebel 30 und 32 bei der Abwärts- und bei der Aufwärtsbewegung und die Zeitpunkte der Geschwindigkeitsänderungen und der Auslenkung der Effekthebel zufällig innerhalb bestimmter, vorgebbarer Grenzen. Die kommandierte Abwärtsgeschwindigkeit liegt also stets innerhalb eines vorgegebenen, sinnvollen Geschwindigkeitsintervalls, folgt aber innerhalb dieses Geschwindigkeitsintervalls einer Zufallsverteilung.The effect lever drive 34 and the feed drive 24 are controlled by an electronic control unit 50. The electronic control unit 50 contains a random generator. The control unit 50 accordingly controls the feed speed such as the angular speed of the effect levers 30 and 32 during the downward and upward movement and the times of the speed changes and the deflection of the effect levers at random within certain, predetermined limits. The commanded downward speed is therefore always within a predetermined, reasonable speed interval, but follows a random distribution within this speed interval.
