Description

Die Erfindung betrifft eine Ringspinnvorrichtung mit wenigstens einer Spinnstelle, die ein Streckwerk und eine Ringspindel enthält, wobei eine Falschdralleinrichtung für einen zu verdrehenden Faserverband zwischen Streckwerk und Ringspindel angeordnet ist, an die der Faserverband seitlich anlegbar ist.The invention relates to a ring spinning device with at least one spinning station, which includes a drafting system and a ring spindle, wherein a false twisting device is arranged for a twisting fiber structure between drafting and ring spindle, to which the fiber structure is applied laterally.

DE-161971-A zeigt den Oberbegriff vom Anspruch 1. DE-161971-A shows the preamble of claim 1.

Eine derartige Ringspinnvorrichtung ist aus der JP62-231039 A bekannt. Die Falschdralleinrichtung enthält eine Siebtrommel, an die der vom Streckwerk kommende und zu verdrehende Faserverband angelegt wird. Der Faserverband läuft über die Umfangsfläche der Siebtrommel. Die Rotationsachse der Siebtrommel ist parallel zum Faserverband angeordnet. Im Innern der Siebtrommel ist ein Saugeinsatz angeordnet, über den der Faserverband an die Oberfläche der Siebtrommel angesaugt wird. Durch die Rotation der Siebtrommel wird dem an die Umfangsfläche angesaugten Faserverband ein Falschdrall erteilt.Such a ring spinning device is known from JP62-231039 A known. The false twisting device contains a sieve drum to which the fiber structure coming from the drafting system and to be twisted is applied. The fiber structure runs over the peripheral surface of the sieve drum. The axis of rotation of the screening drum is arranged parallel to the fiber structure. Inside the screen drum, a suction insert is arranged, via which the fiber structure is sucked to the surface of the screen drum. Due to the rotation of the sieve drum, the false twist is imparted to the fiber structure sucked onto the circumferential surface.

Die meisten Fadenbrüche entstehen beim Ringspinnen im Bereich unmittelbar im Anschluss an das Ausgangswalzenpaar des Streckwerks, wenn der zu verdrehende Faserverband die Ausgangsklemmlinie verlässt. Dort kann ein so genanntes Spinndreieck vorhanden sein, das eine Schwachstelle des Faserverbandes auf seinem Weg zur Ringspindel darstellt. Die Drehungsfortpflanzung in dem Faserverband wird, ausgehend von der Ringspindel, oftmals auch dadurch behindert, dass zwischen Ausgangswalze des Streckwerks und Ringspindel ein Fadenführer angeordnet ist. Dieser Fadenführer wird auch als "Sauschwänzchen" bezeichnet.Most yarn breaks occur in ring spinning in the area immediately following the pair of output rollers of the drafting system when the fiber strand to be twisted leaves the output clamping line. There, a so-called spin triangle may be present, which represents a weak point of the fiber structure on its way to the ring spindle. The rotation propagation in the fiber structure, starting from the ring spindle, often also hindered by the fact that a thread guide is arranged between the output roller of the drafting and ring spindle. This thread guide is also called "Sauschwänzchen".

Durch eine Falschdralleinrichtung zwischen Streckwerk und Ringspindel kann die Drehung des Faserverbandes unmittelbar im Anschluss an die Ausgangsklemmlinie, also insbesondere im Bereich eines Spinndreiecks, erhöht werden, so dass sich die Zahl der Fadenbrüche verringern lässt. Die aus JP62-231039 A bekannte Falschdralleinrichtung benötigt eine Unterdruckversorgung und weist somit einen relativ hohen Energieverbrauch auf.By a false twisting device between drafting and ring spindle, the rotation of the fiber structure immediately following the Ausgangsklemmlinie, ie in particular in the region of a spinning triangle, can be increased, so that reduce the number of thread breaks leaves. From JP62-231039 A known false twisting device requires a vacuum supply and thus has a relatively high energy consumption.

Es sind auch Falschdralleinrichtungen verschiedener Art bekannt, die ohne Unterdruckversorgung arbeiten. Diese Falschdralleinrichtungen weisen rotierende Elemente auf, die eine Öffnung für den Faserverband enthalten. Bei der Behebung eines Fadenbruchs muss der Faden durch die Öffnung der Falschdrallelemente hindurchgefädelt werden. Der Aufwand für die Behebung eines Fadenbruchs ist dadurch wesentlich erhöht. Insgesamt kann der Bedien- und Wartungsaufwand der Ringspinnmaschine durch derartige Falschdralleinrichtungen nicht verringert werden, selbst wenn sich die Anzahl der Fadenbrüche reduziert.There are also false twisting devices of various types known that work without vacuum supply. These false twist devices have rotating elements which contain an opening for the fiber structure. When eliminating a thread breakage, the thread must be threaded through the opening of the false twist elements. The cost of repairing a thread breakage is thereby substantially increased. Overall, the operating and maintenance costs of the ring spinning machine can not be reduced by such false-twisting devices, even if the number of yarn breaks is reduced.

Der Erfindung liegt die Aufgabe zugrunde, eine verbesserte Falschdralleinrichtung für eine Ringspinnvorrichtung zu schaffen.The invention has for its object to provide an improved false twist device for a ring spinning device.

Die Aufgabe gemäß Anspruch 1 gelöst.The object is achieved according to claim 1.

Der zu verdrehende Faserband liegt auf der Reibfläche der rotierenden Scheiben auf und wird durch die Reibfläche um sich selbst verdreht und erhält dadurch einen Falschdrall. Im Vergleich zu einer pneumatischen Falschdralleinrichtung ist für die Falschdralleinrichtung wesentlich weniger Energieeinsatz erforderlich. Bei einer Behebung eines Fadenbruchs, also beim Anspinnen der Spinnstelle, ist kein erhöhter Arbeitsaufwand erforderlich. Der zu verdrehende Faserverband legt sich von selbst an die Reibfläche der rotierbaren Scheibe an. Es ist kein Einfädeln erforderlich. Die Reibfläche ist bevorzugt am Außenumfang der Scheibe angeordnet.The sliver to be twisted rests on the friction surface of the rotating disks and is rotated around itself by the friction surface and thus receives a false twist. Compared to a pneumatic false twist device much less energy input is required for the false twist device. When correcting a thread break, so when piecing the spinning station, no increased workload is required. The fiber strand to be twisted applies itself to the friction surface of the rotatable disc. There is no threading required. The friction surface is preferably arranged on the outer circumference of the disc.

Es ist vorteilhaft, dass die Rotationsrichtung der Scheibe so gerichtet ist, dass der Faserverband durch die Falschdralleinrichtung in der gleichen Drehrichtung gedreht wird, wie durch die Ringspindel. Die Drehung des Faserverbandes lässt sich temporär erhöhen, so dass die Gefahr eines Fadenbruchs sich verringert. Insbesondere lässt sich die Drehung des Faserverbandes in dem Bereich zwischen der Ausgangsklemmlinie des Streckwerks und der Falschdralleinrichtung erhöhen. Die Festigkeit des Faserverbandes in seinem schwächsten Bereich unmittelbar im Anschluss an die Ausgangsklemmlinie, wo sich auch das Spinndreieck befindet, wird dadurch erhöht.It is advantageous that the direction of rotation of the disc is directed so that the fiber structure is rotated by the false twist device in the same direction of rotation, as by the ring spindle. The rotation of the fiber structure can be temporarily increased, so that the risk of yarn breakage is reduced. In particular, the rotation of the fiber structure in the region between the output clamping line of the drafting system and the false twist device can be increased. The strength of the fiber structure in its weakest area immediately after the Ausgangsklemmlinie, where the spinning triangle is located, is thereby increased.

Es ist vorteilhaft, dass der Faserverband durch die zwei benachbarten Scheiben geführt wird, so dass solche mit einem Achsabstand angeordnet sind, der kleiner als der Scheibendurchmesser ist. Zwei benachbarte Scheiben überlappen sich, und es entsteht ein Keilspalt. Der Faserverband legt sich in den Keilspalt der beiden benachbarten Scheiben und wird dort sicher positioniert. Durch die Reibflächen der beiden Scheiben wird dem Faserverband eine Drehung erteilt. Die benachbarten Scheiben rotieren gleichsinnig.It is advantageous that the fiber bundle is passed through the two adjacent discs, so that those are arranged with an axial distance which is smaller than the disc diameter. Two adjacent disks overlap and a wedge gap is created. The fiber structure settles in the wedge gap of the two adjacent disks and is securely positioned there. Through the friction surfaces of the two discs, the fiber structure is given a rotation. The adjacent discs rotate in the same direction.

Um eine gute Auflage des Faserverbandes auf der Reibfläche und somit eine sichere Drehungserteilung zu gewährleisten, ist es vorteilhaft, dass die Falschdralleinrichtung so zwischen einer Ausgangsklemmlinie des Streckwerks und einem der Ringspindel vorgeordneten Fadenführer angeordnet ist, dass der Faserverband durch die Falschdralleinrichtung aus der kürzesten Verbindungslinie zwischen Ausgangsklemmlinie und Fadenführer ausgelenkt wird. Diese Anordnung ist insbesondere vorteilhaft, wenn der Faserverband in dem Keilspalt von den zwei benachbarten Scheiben geführt wird.In order to ensure a good circulation of the fiber structure on the friction surface and thus a reliable rotation distribution, it is advantageous that the false twisting device is arranged between an output clamping line of the drafting system and one of the ring spindle upstream yarn guide, that the fiber structure by the false twisting device from the shortest connecting line between Output terminal line and thread guide is deflected. This arrangement is particularly advantageous when the fiber structure in the wedge gap is guided by the two adjacent disks.

In Ausgestaltung der Erfindung kann es vorteilhaft sein, dass der Scheibendurchmesser der rotierbaren Scheiben größer ist als die Teilung der Ringspinnvorrichtung. Die Anzahl der Scheiben in der Ringspinnvorrichtung ist dann um eine Scheibe höher als die Anzahl der nebeneinander angeordneten Spinnstellen. Diese Ausgestaltung ist insbesondere dann vorteilhaft, wenn die Teilung der Ringspinnvorrichtung, also der Abstand von Spinnstelle zu Spinnstelle, sehr klein ist, wie es häufig bei der Verarbeitung von Kurzstapelfasern üblich ist.In an embodiment of the invention, it may be advantageous that the disk diameter of the rotatable disks is greater than the pitch of the ring spinning device. The number of discs in the ring spinning device is then one slice higher than the number of juxtaposed spinning stations. This embodiment is particularly advantageous if the Division of the ring spinning device, so the distance from spinning station to spinning station is very small, as is common in the processing of short staple fibers.

Weitere Vorteile und Merkmale der Erfindung ergeben sich aus der nachfolgenden Beschreibung einiger Ausführungsbeispiele.Further advantages and features of the invention will become apparent from the following description of some embodiments.

  • FIG. 2 a very schematic view in the direction of arrow II the FIG. 1 on two adjacent false twisting devices,
  • FIG. 3 a view similar FIG. 2 to a differently configured false twisting device,
  • FIG. 4 a very schematic view of a false twisting device in the direction of arrow IV of FIG. 1 ,

In Figur 1 ist sehr schematisch eine Spinnstelle 1 einer Ringspinnvorrichtung 2 dargestellt. Die Spinnstelle enthält ein Streckwerk 3, eine Falschdralleinrichtung 4 und eine Ringspindel 5. Von dem Streckwerk 3 ist lediglich das aus einer Unterwalze 6 und einer daran angedrückten Oberwalze 7 bestehende Ausgangswalzenpaar 6,7 dargestellt. Das Streckwerk 3 kann in an sich bekannter Weise weitere nicht dargestellte Walzenpaare enthalten, um einen Faserverband 8 aus Stapelfasern auf die gewünschte Feinheit zu verziehen. An der Klemmlinie 9 des Ausgangswalzenpaares 6,7 ist der Faserverband 8 fertig verzogen und wird in Transportrichtung A an die Ringspindel 5 geliefert.In FIG. 1 is very schematically a spinning station 1 a ring spinning device 2 shown. The spinning station contains a drafting system 3, a false twisting device 4 and a ring spindle 5. Of the drafting system 3, only the existing of a lower roller 6 and an upper roller 7 pressed thereon roller pair 6,7 is shown. The drafting system 3 may include in a conventional manner further roller pairs, not shown, to forgive a fiber structure 8 of staple fibers to the desired fineness. At the nip line 9 of the output roller pair 6.7 of the fiber structure 8 is finished warped and is delivered in the transport direction A to the ring spindle 5.

Die Ringspindel 5 enthält einen Kops 10 zum Aufwinden des zu einem Garn verdrehten Faserverbandes 8. Der Kops 10 wird in Rotation versetzt. Der Ringspindel 5 ist ein Spinnring 11 und ein Ringläufer 12 zugeordnet. Der Ringspindel 5 ist ein Fadenführer 13 vorgeordnet, der auch als "Sauschwänzchen" bezeichnet wird. Der vom Streckwerk 3 gelieferte Faserverband 8 durchläuft den Fadenführer 13 und den Läufer 12 und wird auf den Kops aufgewunden. Dabei wird dem Faserverband 8 in an sich bekannter Weise seine Spindrehung erteilt. Die Spinndrehung läuft entgegen der Transportrichtung A bis zum Ausgangswalzenpaar 6,7 des Streckwerks 3 zurück. In dem Bereich unmittelbar im Anschluss an die Ausgangsklemmlinie 9 kann ein Spinndreieck vorhanden sein, das die schwächste Stelle des Faserverbandes zwischen Ausgangsklemmlinie 9 und Ringspindel 5 darstellt. Durch die Reibung des Faserverbandes 8 an dem Fadenführer 13 wird das Zurücklaufen der Spinndrehung zum Streckwerk 3 behindert.The ring spindle 5 includes a cop 10 for winding up the twisted into a yarn fiber structure 8. The cop 10 is set in rotation. The ring spindle 5 is associated with a spinning ring 11 and a ring traveler 12. The ring spindle 5 is preceded by a yarn guide 13, which is also referred to as "Sauschwänzchen". The supplied from the drafting 3 fiber strand 8 passes through the yarn guide 13 and the rotor 12 and is wound on the cop. Here, the fiber structure 8 is granted in a conventional manner its spin rotation. The spin rotation runs back against the transport direction A to the pair of output rollers 6, 7 of the drafting system 3. In the area immediately after the output terminal line 9, a spinning triangle be present, which represents the weakest point of the fiber structure between the output clamping line 9 and ring spindle 5. Due to the friction of the fiber structure 8 on the yarn guide 13, the running back of the spinning rotation to the drafting 3 is hindered.

Die Falschdrallrichtung 4 ist zwischen dem Ausgangswalzenpaar 6, 7 und dem Fadenführer 13 angeordnet. Die Falschdralleinrichtung 4 enthält eine rotierbare Scheibe 14, die an ihrem Außenumfang eine Reibfläche 15 für den Faserverband 8 aufweist. Die Rotationsachse der Scheibe 14 ist durch die strichpunktierte Linie 16 angedeutet. Die Scheiben 14 ist über eine Lagerung 17 und einen Halter 18 ortsfest in der Ringspinnvorrichtung 2 angebracht. Die Scheibe 14 ist mit einem Wirtel 19 verbunden, der von einem Riemen 20 angetrieben wird. In alternativer, nicht dargestellter Ausgestaltung, kann der Scheibe 14 ein eigener Antriebsmotor zugeordnet sein.The false twist direction 4 is arranged between the pair of output rollers 6, 7 and the thread guide 13. The false twist device 4 contains a rotatable disc 14, which has a friction surface 15 for the fiber structure 8 on its outer circumference. The axis of rotation of the disc 14 is indicated by the dotted line 16. The discs 14 is fixedly mounted in the ring spinning device 2 via a bearing 17 and a holder 18. The disc 14 is connected to a whorl 19 which is driven by a belt 20. In an alternative, not shown embodiment, the disc 14 may be associated with its own drive motor.

Die Falschdralleinrichtung 4 ist so zwischen der Ausgangsklemmlinie 9 und dem Fadenführer 13 angeordnet, dass der Faserverband 8 durch die Falschdralleinrichtung 4 aus der kürzesten Verbindungslinie zwischen Ausgangsklemmlinie 9 und Fadenführer 13 ausgelenkt wird. Der Faserverband 8, der in dem Bereich zwischen Streckwerk und Ringspindel einer gewissen Zugspannung unterliegt, wird dadurch an die Reibfläche 15 der Scheibe 14 angelegt und kann durch die rotierende Scheibe 14 verdreht werden. Der Faserverband 8 wird an der Reibfläche 15 der Falschdralleinrichtung 4 umgelenkt.The false twisting device 4 is arranged between the output clamping line 9 and the yarn guide 13 such that the fiber structure 8 is deflected by the false twisting device 4 from the shortest connecting line between the output clamping line 9 and yarn guide 13. The fiber structure 8, which is subject to a certain tensile stress in the region between the drafting system and the ring spindle, is thereby applied to the friction surface 15 of the disk 14 and can be rotated by the rotating disk 14. The fiber structure 8 is deflected at the friction surface 15 of the false twist device 4.

Um eine sichere Führung und Drallerteilung des Faserverbandes 8 an der Falschdralleinrichtung 4 zu gewährleisten, ist vorgesehen, dass der Faserverband 8 durch zwei benachbarte Scheiben 14 geführt wird, die mit einem Achsabstand angeordnet sind, der kleiner als der Scheibendurchmesser ist. Die beiden benachbarten Scheiben 14a und 14b sind dabei in axialer Richtung der Rotationsachse 16 versetzt zueinander angeordnet. Die Anordnung zweier benachbarter Scheiben 14a und 14b der Falschdralleinrichtung 4 ist in Figur 2 dargestellt. Die beiden benachbarten Scheiben 14a, 14b überlappen sich und bilden dadurch einen Keilspalt 21, in dem der Faserverband 8 der Spinnstelle 1 geführt wird. Die beiden Scheiben 14a, 14b rotieren gleichsinnig in Rotationsrichtung B. Beide Scheiben 14a, 14b werden über ihre Wirtel 19a, 19b von einem gemeinsamen Tangentialriemen 20 angetrieben. Eine zu der Spinnstelle 1 benachbarte Spinnstelle 1' zur Verarbeitung eines Faserverbandes 8' enthält eine eigene Falschdralleinrichtung 4', die ebenfalls zwei Scheiben 14a', 14b' enthält. Die Falschdralleinrichtung 4' der benachbarten Spinnstelle 1' wird von demselben Riemen 20 angetrieben, der bevorzugt durch die gesamte Ringspinnvorrichtung 2 durchläuft. Zwischen den beiden Falschdralleinrichtungen 4 und 4' kann eine Umlenkrolle 22 für den Riemen 20 vorgesehen sein. Der Abstand der benachbarten Faserverbände 8 und 8' in der Ringspinnvorrichtung 2 wird auch als "Teilung" bezeichnet. Der Außendurchmesser der Scheiben 14 ist kleiner als die Teilung der Ringspinnvorrichtung 2.In order to ensure a secure guidance and twist distribution of the fiber structure 8 on the false twisting device 4, it is provided that the fiber structure 8 is guided by two adjacent disks 14, which are arranged with an axial spacing which is smaller than the disk diameter. The two adjacent disks 14a and 14b are arranged offset in the axial direction of the axis of rotation 16 to each other. The arrangement of two adjacent disks 14a and 14b of the false twist device 4 is in FIG. 2 shown. The two adjacent disks 14a, 14b overlap and thereby form a wedge gap 21, in which the fiber structure 8 of the spinning station 1 is guided. The two disks 14a, 14b rotate in the same direction in the direction of rotation B. Both disks 14a, 14b are driven via their whorls 19a, 19b by a common tangential belt 20. A spinning station 1 'adjacent to the spinning station 1 for processing a fiber structure 8' contains its own false twist device 4 ', which likewise contains two disks 14a', 14b '. The false twist device 4 'of the adjacent spinning station 1' is driven by the same belt 20, which preferably passes through the entire ring spinning device 2. Between the two false twist devices 4 and 4 ', a deflection roller 22 may be provided for the belt 20. The distance of the neighboring ones Fiber composites 8 and 8 'in the ring spinning device 2 is also referred to as "division". The outer diameter of the discs 14 is smaller than the pitch of the ring spinning device. 2

In Figur 3 ist eine Variante einer Falschdralleinrichtung 4 dargestellt. Es sind ähnlich wie in Figur 2 zwei benachbarte Spinnstellen 1 und 1' dargestellt. Der Faserverband 8 wird im Keilspalt 23 von zwei benachbarten Scheiben 24 und 25 geführt. Der Faserverband 8' der benachbarten Spinnstelle 1' wird durch einen Keilspalt 23' geführt, der durch die Scheibe 25 und eine weitere Scheibe 26 gebildet wird. Der Außendurchmesser der Scheiben 24, 25, 26 ist größer als die Teilung der Ringspinnvorrichtung 2. Der Achsabstand der Scheiben 24, 25, 26 ist kleiner als der Scheibendurchmesser. Es sind bei dieser Variante insgesamt weniger Scheiben notwendig. Die Anzahl der Scheiben entspricht der Anzahl der nebeneinander angeordneten Spinnstellen plus einer weiteren Scheibe am Anfang.In FIG. 3 a variant of a false twist device 4 is shown. They are similar to FIG. 2 two adjacent spinning stations 1 and 1 'shown. The fiber structure 8 is guided in the wedge gap 23 by two adjacent disks 24 and 25. The fiber structure 8 'of the adjacent spinning station 1' is guided by a wedge-shaped gap 23 ', which is formed by the disk 25 and a further disk 26. The outer diameter of the discs 24, 25, 26 is greater than the pitch of the ring spinning device 2. The center distance of the discs 24, 25, 26 is smaller than the disc diameter. There are a total of fewer discs required in this variant. The number of disks corresponds to the number of juxtaposed spinning stations plus another disk at the beginning.

In Figur 1 verläuft die Rotationsachse 16 der Scheibe 14 im Wesentlichen parallel zum Faserverband 8 zwischen Streckwerk 3 und Falschdralleinrichtung 4. In nicht dargestellter Ausgestaltung kann es vorteilhaft sein, dass die Rotationsachse 16 einen Winkel zu dem Faserverband 8 aufweist. So dass die Falschdralleinrichtung eine Förderwirkung auf den Faserverband 8 ausübt. Die Förderwirkung ist bevorzugt entgegengesetzt der Transportrichtung A gerichtet, so dass die Zugspannung des Faserverbandes 8 im Bereich zwischen Ausgangsklemmlinie 9 und Falschdralleinrichtung 4 reduziert wird.In FIG. 1 the axis of rotation 16 of the disc 14 is substantially parallel to the fiber structure 8 between drafting 3 and false twist device 4. In an embodiment, not shown, it may be advantageous that the axis of rotation 16 has an angle to the fiber structure 8. So that the false twist device exerts a conveying effect on the fiber structure 8. The conveying effect is preferably directed opposite to the transport direction A, so that the tensile stress of the fiber structure 8 is reduced in the region between the output clamping line 9 and false twisting device 4.

Eine bevorzugte Ausgestaltung einer Falschdralleinrichtung 4 mit einer Förderwirkung auf den Faserverband 8 ist in Figur 4 erkennbar. Der Faserverband 8 wird im Keilspalt 27 von zwei gleichsinnig rotierenden Scheiben 28 und 29 geführt und mit einer Drehung versehen. Die Rotationsachse 30 der Scheibe 28 verläuft im Wesentlichen parallel zum Faserverband 8. Die Rotationsachse 31 der Scheibe 29 weist einen Winkel zu dem Faserverband 8 auf und übt eine Förderwirkung auf den Faserverband 8 aus. Bei der Darstellung in Figur 4 sollen der Faserverband 8 und die Rotationsachse 30 in der Zeichenebene verlaufen, während die Rotationsachse 31 einen kleinen Winkel zur Zeichenebene aufweist. Die Rotationsachsen 30 und 31 weisen also ebenfalls einen kleinen Winkel zueinander auf. Die Rotationsachse 31 ist somit leicht verschränkt zu der Rotationsachse 30 angeordnet.A preferred embodiment of a false twist device 4 with a conveying effect on the fiber structure 8 is in FIG. 4 recognizable. The fiber structure 8 is guided in the wedge-shaped gap 27 by two disks 28 and 29 rotating in the same direction and provided with a rotation. The axis of rotation 30 of the disc 28 extends substantially parallel to the fiber structure 8. The axis of rotation 31 of the disc 29 has an angle to the fiber structure 8 and exerts a conveying effect on the fiber structure 8. When displayed in FIG. 4 should the fiber structure 8 and the axis of rotation 30 extend in the plane of the drawing, while the axis of rotation 31 has a small angle to the plane of the drawing. The rotation axes 30 and 31 thus also have a small angle to each other. The rotation axis 31 is thus arranged slightly entangled to the rotation axis 30.
