Abstract

The yarn feed unit, using two rollers (1,2) to move the yarn through between them, has a roller (2) on a floating mounting as a rotation symmetrical hollow body. Its inner wall is supported by a spherical support body (12) on the axis shaft (3). The floating yarn feed roller is on a static axis shaft, and the support has a ball shape. Limits (13,14) are against the floating roller, aligned parallel to the plane through the axes of both rollers on one side and at right angles to the roller gap on the other side. One roller is given a swing movement against the other roller, through its mounting on a swing arm (10) fitted with a spring (11). The swing arm carries a motor for the roller drive.

Description

Die Erfindung betrifft ein Fadenlieferwerk mit zwei Lieferwerkrollen, von denen die eine Rolle federnd gegen die andere Rolle anstellbar ist, wobei eine der beiden Rollen derart schwimmend gelagert ist, daß sie in der Lage ist, Schwenk- bzw. Pendelbewegungen relativ zur anderen Rolle durchzuführen.The invention relates to a yarn feeder with two feeder rollers, of which the one role is resilient against the other role, one of the two roles is floating so that it is able to swivel or pendulum movements to perform relative to the other role.

Bei derartigen, z. B. in der DE-OS 26 58 995 beschriebenen, Fadenlieferwerken wird mindestens eine der beiden Rollen von außen her rotatorisch angetrieben, während die andere nicht von außen her angetriebene Rolle von dem durch den Rollenspalt geförderten Faden in Drehung gesetzt wird. Die beiden Rollen sind parallel zueinander ausgerichtet, wobei eine der beiden Rollen zum Einlegen eines Fadens in das Lieferwerk in der Regel von der anderen Rolle entweder translatorisch oder schwenkbar weg bewegt und nach dem Einlegen des Fadens wieder an die andere Rolle anstellbar ist. Bei den bekannten Fadenlieferwerken ist während des Betriebs des Fadenlieferwerks der Abstand zwischen den beiden Rollen im wesentlichen durch die Fadendicke des hindurchlaufenden Fadens bestimmt, wobei dieser Abstand im Idealfall über die gesamte Rollenlänge konstant sein soll. Zur Verbesserung der Achsparallelität zwischen den beiden Rollen ist bei dem in der DE-OS 26 58 995 beschriebenen Fadenlieferwerk eine der beiden Rollen an einem federbelasteten Schwenkarm gelagert, der als selbstzentrierender, um einen Drehpunkt schwenkbarer Pendelarm ausgebildet ist. Es wird dabei davon ausgegangen, daß durch Verbesserung der Achsparallelität eine Vergleichmäßigung des auf den zu fördernden Faden ausgeübten Klemmdrucks und damit eine gleichmäßige Fadenförderung erreicht wird.In such, e.g. B. described in DE-OS 26 58 995, yarn feeders at least one of the two rollers is driven in rotation from the outside, while the other non-externally driven roller from that conveyed through the roller nip Thread is set in rotation. The two roles are aligned parallel to each other, one of the two rollers for inserting a thread into the delivery plant usually away from the other role either translationally or pivotally moved and can be adjusted to the other reel after inserting the thread. In the known yarn feeder is during the operation of the yarn feeder the distance between the two rollers essentially by the thread thickness of the passing thread determined, this distance ideally over the entire Roll length should be constant. To improve axis parallelism between the two roles is in the yarn feed mechanism described in DE-OS 26 58 995 one of the two rollers is mounted on a spring-loaded swivel arm, which acts as a self-centering, swing arm is designed to be pivotable. It will assumed that by improving the parallelism of the axes an equalization of the clamping pressure exerted on the thread to be conveyed and thus uniform thread conveyance is achieved.

Der vorliegenden Erfindung liegt die Problematik zugrunde, die dann auftritt, wenn mit dem Lieferwerk gleichzeitig zwei Fäden mit unterschiedlichen Dicken oder Titern einer Maschine, zum Beispiel zur Herstellung von Effektgarn, zugefördert werden sollen, da sich dann der Rollenspalt auf die Dicke des dickeren Fadens einstellt und damit der dünnere Faden von den Rollen unbeeinflußt bleibt.The present invention is based on the problem that arises when two threads with different thicknesses or titers at the same time with the supplier a machine, for example for the production of fancy yarn should, since then the roller gap adjusts to the thickness of the thicker thread and so that the thinner thread remains unaffected by the rolls.

Auch wenn durch das Fadenlieferwerk zwei oder mehrere Fäden gleicher Dicke hindurchgeführt werden, kann, wenn z. B. einer der durchlaufenden Fäden eine momentane Fadenverdickung aufweist, sich der Abstand zwischen den beiden Rollen entsprechend dieser Fadenverdickung vergrößern mit der Folge, daß dann der andere Faden nicht mehr in Kontakt mit den Oberflächen beider Rollen ist. Dadurch kann es zu einem Schlupf und damit zu einer nicht mehr gleichförmigen Förderung dieses zweiten Fadens oder Fadenabschnitts kommen. Wenn andererseits einer der beiden Fäden gegenüber dem anderen Faden eine momentane Fadeneinschnürung aufweist, wird dieser die Fadeneinschnürung aufweisende Faden oder Fadenabschnitt nicht mehr schlupffrei zwischen den beiden Rollen hindurchlaufen, da entsprechend der Dicke des anderen Fadens oder Fadenabschnitts sich der Abstand zwischen den beiden Rollen nicht verändern, d. h. verkleinern kann.Even if two or more threads of the same thickness are passed through the thread feed mechanism can, if z. B. one of the threads running through a momentary Has thread thickening, the distance between the two rollers accordingly enlarge this thread thickening with the result that the other then Thread is no longer in contact with the surfaces of both rolls. It can to slip and thus to a no longer uniform promotion of this second thread or thread section come. If, on the other hand, one of the two Threads has a momentary thread constriction compared to the other thread, this thread or thread section having the thread constriction will not run more slip-free between the two rollers, because the Thickness of the other thread or thread section is the distance between the two Do not change roles, d. H. can shrink.

Dadurch, daß bei dem in der DE-OS 26 58 995 beschriebenen Fadenlieferwerk der die eine Rolle tragende Schwenkarm als selbstzentrierender, um einen Drehpunkt schwenkbarer Pendelarm ausgebildet ist, ist dieses bekannte Lieferwerk in der Lage, das oben geschilderte Problem bei der gleichzeitigen Förderung von zwei Fäden zu lösen, selbst wenn an sich mit diesem bekannten Lieferwerk angestrebt ist, die Achsparallelität zwischen den beiden Rollen zu verbessern. lösen, selbst wenn an sich mit diesem bekannten Lieferwerk angestrebt ist, die Achsparallelität zwischen den beiden Rollen zu verbessern.
Der Nachteil des bekannten Lieferwerkes besteht darin, daß ein relativ großes System um den Drehpunkt pendelnd aufgehängt ist, nämlich neben der Rolle auch der diese Rolle tragende und zusätzlich auch noch federbelastete Schwenkarm.Characterized in that in the thread delivery mechanism described in DE-OS 26 58 995 the swivel arm carrying a role is designed as a self-centering pendulum arm which can be pivoted about a pivot point, this known delivery mechanism is able to solve the problem described above while simultaneously promoting two To solve threads, even if the goal is to improve the parallelism of the axes between the two rollers. solve, even if the aim of this known delivery system is to improve the axis parallelism between the two rollers.
The disadvantage of the known delivery system is that a relatively large system is suspended from the pivot point, namely in addition to the role also the swing arm carrying this role and also spring-loaded.

Der Erfindung liegt die Aufgabe zugrunde, ein demgegenüber vereinfachtes Fadenlieferwerk zur gleichzeitigen Zulieferung von zwei Fäden zu schaffen, bei dem unabhängig von unterschiedlichen Dicken oder Titern der beiden Fäden oder von auftretenden Fadenverdickungen oder Fadeneinschnürungen in jedem Fall eine gleichmäßige schlupffreie Förderung beider Fäden oder Fadenabschnitte gewährleistet ist.The invention is based on the object, a simplified thread delivery mechanism to provide for the simultaneous supply of two threads, with which independently of different thicknesses or titers of the two threads or of occurring Thread thickening or thread constriction in any case an even slip-free conveyance of both threads or thread sections is guaranteed.

Zur Lösung dieser Aufgabe ist das erfindungsgemäße Fadenlieferwerk dadurch gekennzeichnet, daß die schwimmend gelagerte Rolle als rotationssymmetrischer Hohlkörper ausgebildet ist, der mit seiner Innenwand auf einem auf einer Achswelle befestigten, balligen Stützkörper ausgebildet ist, derart, daß die Lage der schwimmend gelagerten Rolle nur in einer durch die Achsen der beiden Rollen bestimmten Ebene veränderbar ist.To achieve this object, the yarn feed mechanism according to the invention is characterized in that that the floating roller as a rotationally symmetrical hollow body is formed, with its inner wall on a fixed on an axle shaft, spherical support body is formed such that the position of the floating stored role only in a plane determined by the axes of the two roles is changeable.

Infolge der schwimmenden Lagerung allein dieser Rolle ist diese, unbeeinflußt durch zu hohe Massenkräfte, in der Lage, sich bei durch das Lieferwerk hindurchlaufenden Fadenverdickungen oder Fadeneinschnürungen eines der beiden Fäden schräg zu stellen, so daß die auf beide auf das Lieferwerk hindurchlaufenden Fadenabschnitte einwirkenden Anpreßkräfte konstant bleiben, so daß beide Fadenabschnitte schlupffrei und damit gleichmäßig durch das Lieferwerk gefördert werden.As a result of the floating bearing of this role alone, it is unaffected by Too high mass forces, able to move through the delivery plant Thread thickening or thread constriction one of the two threads at an angle set so that the thread sections running through both on the delivery mechanism acting contact forces remain constant, so that both thread sections slip-free and thus be evenly promoted by the supplier.

Der auf der insbesondere stationären Achswelle gelagerte Stützkörper hat vorzugsweise die Form einer Kugel.The support body mounted on the in particular stationary axle shaft preferably has the shape of a ball.

Um ein Ausweichen der schwimmend gelagerten Lieferwerkrolle in einer Richtung zu verhindern, die außerhalb der durch die Achsen der beiden Rollen bestimmten Ebene liegt, ist das Fadenlieferwerk gemäß einer bevorzugten Ausführungsform gekennzeichnet durch gegen die schwimmend gelagerte Rolle anliegende Anschläge, die parallel zu der durch die Achsen der beiden Rollen gelegte Ebene einerseits und senkrecht zum Rollenspalt des Lieferwerks andererseits ausgerichtet sind.To avoid the floating supply reel in one direction prevent the outside of the plane determined by the axes of the two roles lies, the thread feed mechanism is characterized according to a preferred embodiment by abutting against the floating roller, the parallel to the plane through the axes of the two rollers on the one hand and perpendicular on the other hand are aligned with the roll gap of the supplying plant.

Das erfindungsgemäße Fadenlieferwerk kann auch bei einem System gemäß der EP 0 701 014 B1 (= US-PS 5,626,011) mit besonderem Vorteil verwendet werden, wenn es darum geht, während des Anspinnprozesses bei einem integrierten OE-Spinn- und Doppeldrahtzwirn-Prozeß mit dem Abziehen des Zwirnfadens durch die Spindelhohlachse der Doppeldraht-Zwirnspindel gleichzeitig die beiden Anspinn-Spinnfäden in die OE-Spinnrotoren hinein zu fördern.The yarn feed mechanism according to the invention can also be used in a system according to EP 0 701 014 B1 (= US Pat. No. 5,626,011) can be used with particular advantage if it's about during the piecing process with an integrated OE spinning and Double-wire twisting process with pulling the thread through the hollow spindle axis the double-wire twisting spindle simultaneously the two piecing threads to convey into the OE spinning rotors.

Die Erfindung wird im folgenden anhand der Zeichnungen näher beschrieben:

  • Figur 1 zeigt eine perspektivische Darstellung einer ersten Ausführungsform des erfindungsgemäßen Fadenlieferwerks;
  • Figur 2 zeigt eine perspektivische Darstellung einer zweiten Ausführungsform der Lagerung der einen der beiden Lieferwerkrollen.
    • The invention is described in more detail below with reference to the drawings:
  • Figure 1 shows a perspective view of a first embodiment of the yarn feeder according to the invention;
  • Figure 2 shows a perspective view of a second embodiment of the storage of one of the two delivery rolls.

    • Gemäß Figur 1 besteht das Fadenlieferwerk aus zwei Lieferwerkrollen 1 und 2, von denen die Lieferwerkrolle 1 auf einem federbelasteten Schwenkarm 10 gelagert ist, so daß sie zum Einlegen der Fäden A und B von der Lieferwerkrolle 2 weggeschwenkt und nach dem Einlegen der Fäden wieder an die Rolle 2 angestellt werden kann. An dem Schwenkarm 10 ist z. B. eine Zugfeder 11 mit ihrem einen Ende befestigt, während das andere Ende dieser Zugfeder 11 an einem (nicht dargestellten) stationären Teil z. B. des Fadenlieferwerks oder des Maschinengestells befestigt ist.According to FIG. 1, the thread feed unit consists of two delivery unit rolls 1 and 2, of which the delivery roller 1 is mounted on a spring-loaded swivel arm 10, so that they are pivoted away from the delivery roller 2 for inserting the threads A and B. and can be put back on the reel 2 after inserting the threads. On the swivel arm 10 is, for. B. attached a tension spring 11 with one end while the other end of this tension spring 11 on a stationary (not shown) Part z. B. the thread feeder or the machine frame is attached.

    Gemäß Figur 2 ist die Rolle 2 als Hohlkörper ausgebildet, der mit seiner Innenwand auf einem auf einer stationär gelagerten Achswelle 11 befestigten balligen Stützkörper 12, vorzugsweise in Kugelform, abgestützt ist. Gegen die äußere Umfangsfläche der Rolle 2 oder gegen zur Umfangsfläche konzentrische Ansätze 2.1 dieser Rolle 2 liegen an den entgegengesetzten Enden der Rolle 2 Anschlagkörper 13, 14 an, die parallel zu der durch die Achsen der beiden Rollen 1, 2 gelegten Ebene einerseits und senkrecht zum Rollenspalt des Lieferwerks andererseits ausgerichtet sind. Auf diese Weise ist gewährleistet, daß die Rolle 2 ihre Lage nur um eine Achse in einer Ebene verändern kann, die durch die Achse der beiden Rollen bestimmt ist, während durch die gegen die Oberseite der Rolle 2 anliegenden Anschlagkörper 13, 14 ein Verschwenken bzw. Kippen der Rolle 2 um eine horizontale Achse in einer Ebene verhindert wird, die tangential zu den sich im Bereich des Rollenspaltes berührenden Mantelflächen der beiden Rollen 1, 2 gelegt ist.According to Figure 2, the roller 2 is designed as a hollow body, with its inner wall on a spherical support body attached to a stationary axle shaft 11 12, preferably in spherical form, is supported. Against the outer peripheral surface of the Roll 2 or against the peripheral surface concentric approaches 2.1 of this role 2 at the opposite ends of the roller 2 stopper bodies 13, 14 which are parallel to the plane defined by the axes of the two rollers 1, 2 on the one hand and vertically on the other hand are aligned with the roll gap of the supplying plant. That way ensures that the roller 2 change its position only around an axis in one plane can, which is determined by the axis of the two rollers, while by the counter the top of the roller 2 abutting stop body 13, 14 a pivoting or Tilting of the roller 2 around a horizontal axis in a plane is prevented tangential to the lateral surfaces of the contacting in the area of the roller gap two roles 1, 2 is placed.

    Wenn einer der beiden durch das Lieferwerk hindurchlaufenden Fäden bzw. Fadenabschnitte A und B, z. B. der Fadenabschnitt A, eine Fadenverdickung oder Fadeneinschnürung aufweist, ist die Rolle 2 in der Lage, entsprechend der Fadenverdickung oder Fadeneinschnürung auszuweichen, so daß sich die Rolle 2 relativ zur Rolle 1 entsprechend der Verdickung oder Einschnürung schräg stellt. Der Rollenspalt wird damit im Bereich des Fadenabschnitts A größer oder kleiner, während im Bereich des Fadenabschnitts B der Rollenspalt seine ursprüngliche Größe entsprechend der Fadendicke dieses Fadenabschnitts B behält. Auf diese Weise ist gewährleistet, daß die auf beide Fadenabschnitte A und B von den Rollen 1 und 2 ausgeübten Anpreßkräfte konstant bleiben, wodurch eine gleichmäßige und schlupffreie Förderung beider Fadenabschnitte A und B durch das Lieferwerk gewährleistet ist.If one of the two threads or thread sections passing through the delivery mechanism A and B, e.g. B. the thread section A, a thread thickening or thread constriction has, the roll 2 is able, according to the thread thickening or to avoid thread constriction, so that the roller 2 relative to the roller 1 according to the thickening or constriction. The nip is thus larger or smaller in the area of the thread section A, while in the area of the Thread section B of the roller gap its original size according to the thread thickness this thread section B retains. In this way it is ensured that the on both thread sections A and B from the rollers 1 and 2 applied pressing forces remain constant, which ensures even and slip-free conveyance of both thread sections A and B is guaranteed by the supplier.

    Eine der beiden Rollen, vorzugsweise die Rolle 1, kann gemäß Figur 1 von einem ebenfalls an dem Schwenkarm 10 befestigten Motor 12 angetrieben werden. Ein Antrieb beider Rollen kann, wie aus Figur 2 ersichtlich, auch in der Weise erfolgen, daß auf einen der beiden Fadenabschnitte A bzw. B eine Zugkraft ausgeübt wird, wodurch beide Rollen 1 und 2 entsprechend rotatorisch angetrieben werden und der andere Fadenabschnitt entsprechend mitgefördert wird.According to FIG. 1, one of the two roles, preferably role 1, can be used by one also attached to the pivot arm 10 motor 12 are driven. A drive As can be seen from FIG. 2, both roles can also take place in such a way that a tensile force is exerted on one of the two thread sections A or B, whereby both rollers 1 and 2 are driven in rotation and the other Thread section is promoted accordingly.
