Vorzugsweise ist vorgesehen, daß der Unterwindefaden die Spindel mit weniger als 360° umschlingt und daß die Betätigungsvorrichtung feststehend an der Ringspinnmaschine angeordnet ist.The invention relates to a device for clamping a Unterwindefadens on a spindle of a ring spinning machine, the spindle below a attached cop a fixed clamping ring and one by means of a Actuator axially displaceable to the spindle, with the clamping ring in Has effective clamping connection bringable ferrule and wherein the Clamping surfaces on the clamping ring and clamping sleeve are conically interlocking. It is preferably provided that the underwind thread with less than 360 ° wraps around and that the actuator is fixed to the Ring spinning machine is arranged.

Eine solche Vorrichtungen ist aus der EP 0 775 769 A1 (Z 9532) bekannt. Dort wird der Unterwindefaden zwischen einem kegeligen Klemmring und einer Klemmhülse, die mit kegelstumpfförmigen Klemmflächen selbsthemmend ineinandergreifen, eingeklemmt. In der Praxis hat sich gezeigt, daß die Klemmwirkung in seltenen Fällen infolge Verschmutzung oder Verschleiß versagt.Such a device is known from EP 0 775 769 A1 (Z 9532). There will the underwind thread between a tapered clamping ring and a clamping sleeve, which interlock with self-locking frustoconical clamping surfaces, trapped. In practice it has been shown that the clamping effect is rare fails due to contamination or wear.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die Betriebssicherheit, insbesondere die Klemmwirkung solcher Klemmwirkverbindungen zu verbessern.The present invention has for its object the operational safety, in particular to improve the clamping effect of such clamping active connections.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß die Klemmfläche des Klemmringes und/oder die Klemmfläche der Klemmhülse durch Strukturierung einen höheren Reibwert erhalten. Die Strukturierung kann beispielsweise rillenförmig, verzahnt, gezackt oder mäanderförmig ausgebildet sein. In manchen Fällen kann die erreicht werden. Die Strukturierung kann an beiden oder nur an einem der zusammenwirkenden Klemmelemente angeordnet sein.According to the invention the object is achieved in that the clamping surface of the Clamping ring and / or the clamping surface of the clamping sleeve by structuring get higher coefficient of friction. The structuring can be, for example, groove-shaped, be toothed, serrated or meandering. In some cases, the can be achieved. The structuring can be carried out on both or only on one of the interacting clamping elements can be arranged.

Es ist schon vorgeschlagen worden (Z 9814), im wesentlichen ebene Klemmflächen von gegeneinander bewegbaren und zusammenwirkenden Klemmelementen mit wellen-förmiger Struktur zu versehen. Hierbei hat die wellenförmige Struktur jedoch den Zweck, bei gegenseitigem Verdrehen der beiden Elemente der Klemmvorrichtung den Klemmspalt zu öffnen und den Faden freizugeben.It has already been proposed (Z 9814), essentially flat clamping surfaces of mutually movable and interacting clamping elements with wave-shaped structure. Here, however, the wavy structure has the purpose of mutually twisting the two elements of the clamping device open the nip and release the thread.

Eine vorteilhafte Weiterbildung der Erfindung sieht vor, die Strukturierung von Klemmhülse und Klemmring jeweils ineinandergreifend auszubilden und Klemmhülse und Klemmring verdrehsicher zueinander anzuordnen.An advantageous development of the invention provides for the structuring of To form the clamping sleeve and clamping ring each interlocking and clamping sleeve and the clamping ring must be arranged so that they cannot rotate relative to one another.

Weitere Ausgestaltungen der Erfindung sehen vor, daß mindestens ein Element der Klemmvorrichtung elastisch ausgeführt ist und daß Klemmhülse und Klemmring durch Federwirkung in Klemmstellung gehalten werden.Further refinements of the invention provide that at least one element of the Clamping device is designed to be elastic and that clamping sleeve and clamping ring are held in the clamped position by spring action.

In den Figuren der Zeichnung ist eine Ausführungsform der Erfindung an einer einzelnen Spindel dargestellt. Es versteht sich, daß eine Ringspinnmaschine eine Vielzahl von Spindeln aufweist, deren jede mit dieser Einrichtung ausgestattet ist. Es zeigen

  • Fig. 1 eine Ringspinnspindel in Seitenansicht;
  • Fig. 2 einen den Gegenstand der Erfindung enthaltenden Ausschnitt aus Fig. 1 teils in
       Ansicht, teils im Längsschnitt.
    • In the figures of the drawing, an embodiment of the invention is shown on a single spindle. It is understood that a ring spinning machine has a plurality of spindles, each of which is equipped with this device. Show it
  • Figure 1 is a side view of a ring spinning spindle.
  • Fig. 2 shows a part of the subject of the invention from Fig. 1 partly in
    View, partly in longitudinal section.

    • Wie aus Fig. 1 erkennbar, besteht die Spinnspindel 1 aus einem Spindelunterteil 2, das in einer den Antrieb der Spinnspindel enthaltenden Spindelbank 3 befestigt ist und in dem das drehbare Spindeloberteil 4 gelagert ist. Auf diesem Spindeloberteil 4 ist ein Hülse 5 aufgesteckt, auf der ein zulaufender Faden 6 zu einer Wicklung 7 aufgewunden wird. Hülse 5 und Wicklung 7 bilden den Kops 8. Der zugeführte Faden 6 wird durch einen Ringläufer 9 geführt, der auf einem Spinnring 10 umläuft, der seinerseits in einer auf und ab bewegbaren Ringbank 11 angeordnet ist.As can be seen from Fig. 1, the spinning spindle 1 consists of a lower spindle part 2, the is fastened in a spindle bank 3 containing the drive of the spinning spindle and in which the rotatable upper spindle part 4 is mounted. On this upper spindle part 4 is a Inserted sleeve 5, on which an incoming thread 6 to a winding 7 is wound up. Sleeve 5 and winding 7 form the cop 8. The thread fed 6 is guided by a ring traveler 9, which rotates on a spinning ring 10, the is in turn arranged in an up and down movable ring bench 11.

    Unterhalb des Kopses 8 ist auf dem Spindeloberteil 4 eine Klemmvorrichtung für den Unterwindefaden angeordnet. Wie aus Fig. 2 hervorgeht, umfaßt diese Klemmvorrichtung 12 eine auf dem Spindeloberteil 4 befestigte Büchse 13. Auf dieser Büchse 13 ist mittels Schrauben 14 ein sich an einer Schulter 15 der Büchse abstützender Klemmring 16 leicht auswechselbar gehalten, dessen Außenumfang auf einem Teilbereich kegelstumpfförmig ist. Mittels der Schrauben 14 kann auch ein Trennmesser 17 mit scharfer Schneidkante 18 befestigt sein.Below the cop 8 is a clamping device for the upper spindle part 4 Underwind thread arranged. As is apparent from Fig. 2, this includes Clamping device 12 a sleeve 13 fastened on the upper spindle part 4. On this Bushing 13 is by means of screws 14 on a shoulder 15 of the bushing supporting clamping ring 16 held easily replaceable, the outer circumference a portion is frustoconical. By means of the screws 14 can also Cutting knife 17 can be attached with a sharp cutting edge 18.

    Auf der Büchse 13 ist ferner eine Klemmhülse 19 axial verschiebbar, die mittels einer sich an Schultern auf der Büchse und in der Klemmhülse abstützenden Feder 20 nach oben gegen den Klemmring 16 gedrückt wird. Der obere innere Rand dieser Klemmhülse 19 ist dem kegelstumpfförmigen Bereich des Klemmringes 16 angepaßt innenkegelstumpfförmig ausgebildet. Die beiden einander gegenüberstehenden kegelstumpfförmigen Flächen 21 bzw. 22 des Klemmringes 16 und der Klemmhülse 19 bilden zusammenwirkend die Klemmvorrichtung 12, in der der Faden 6 geklemmt und gehalten werden kann. Die Schrauben 14 durchdringen auch einen Innenbund der Klemmhülse 19 und sichern diese gegen Verdrehen.On the sleeve 13, a clamping sleeve 19 is also axially displaceable, which by means of a on shoulders on the sleeve and in the clamping sleeve supporting spring 20 after is pressed against the clamping ring 16 above. The top inner edge of this Clamping sleeve 19 is adapted to the frustoconical area of the clamping ring 16 frustoconical. The two facing each other frustoconical surfaces 21 and 22 of the clamping ring 16 and the clamping sleeve 19 cooperatively form the clamping device 12 in which the thread 6 is clamped and can be held. The screws 14 also penetrate an inner collar of the Clamping sleeve 19 and secure it against twisting.

    Die Klemmhülse 19 hat einen Außenbund 23, an dem sie mittels einer Betätigungsvorrichtung gegen die Kraft der Feder 20 nach unten verschoben werden kann. Wie aus Fig. 1 erkennbar, kann diese Betätigungsvorrichtung aus einer entlang der Spindelbank 3 verlaufenden Welle 24 bestehen, an der ein Nocken 25 angeordnet ist, mittels dessen durch Drehen der Welle auf die Klemmhülse 19 eine in der Zeichnung nur durch Pfeile A angedeutete Kraft ausübbar ist. The clamping sleeve 19 has an outer collar 23 on which it is actuated can be moved downward against the force of the spring 20. How 1 can be seen, this actuator from a along the Spindle bank 3 extending shaft 24, on which a cam 25 is arranged, by means of which by rotating the shaft on the clamping sleeve 19 one in the drawing force can only be exerted by arrows A.

    Nach Fertigstellen der Fadenwicklung 7 auf dem Kops 8 wird bei auslaufender Spinnspindel 1 die Klemmhülse 19 durch Ausüben der durch die Pfeile A angedeuteten Kraft nach unten gedrückt. Dadurch werden die kegelstumpfförmigen Flächen 21 bzw. 22 des Klemmringes 16 und der Klemmhülse 19 auseinanderbewegt und die Klemmvorrichtung 12 geöffnet. Auf etwa der Hälfte bis drei Vierteln der letzten Umdrehung der Spinnspindel 1 ist ferner die Ringbank 11 so weit nach unten geführt, daß der Faden 6 durch den Ringläufer 9 mit einem entsprechenden Umfangswinkel auf der Fläche 21 des Klemmringes 16 abgelegt wird. Nachdem die Spinnspindel vollständig zum Stillstand gekommen ist, wird die durch die Pfeile A angedeutete Kraft weggenommen, so daß die Feder 20 die Klemmhülse 19 nach oben bewegen und die Fläche 22 der Klemmhülse an die Fläche 21 des Klemmringes 16 anlegen, die Klemmvorrichtung 12 also schließen kann. Dabei wird der Faden 6 in dieser Klemmvorrichtung 12 festgehalten.After the thread winding 7 is finished on the cop 8, the spinning spindle runs out 1, the clamping sleeve 19 by exercising the indicated by the arrows A. Force pressed down. As a result, the frustoconical surfaces 21 and 22 of the clamping ring 16 and the clamping sleeve 19 moved apart and the Clamping device 12 opened. About half to three quarters of the last Rotation of the spinning spindle 1, the ring bench 11 is further guided downwards so far that the thread 6 through the ring traveler 9 with a corresponding circumferential angle the surface 21 of the clamping ring 16 is deposited. After the spinning spindle has come to a complete standstill, is indicated by the arrows A. Force removed so that the spring 20 move the ferrule 19 up and create the surface 22 of the clamping sleeve on the surface 21 of the clamping ring 16, the Clamping device 12 can therefore close. The thread 6 in this Clamping device 12 held.

    Nach Auswechseln der vollen Kopse 8 gegen leere Hülsen kann ausgehend von dem in der Klemmvorrichtung 12 gehaltenen Faden 6 die Bewicklung der neuen leeren Hülse aufgenommen werden.After replacing the full cops 8 with empty sleeves, starting from the in the clamping device 12 held thread 6 the winding of the new empty tube be included.

    Um ein sicheres Klemmen des Fadens 6 zu bewirken, weisen die Flächen 21 und/oder 22 des Klemmringes 16 bzw. der Klemmhülse 19 erfindungsgemäß eine Strukturierung auf. Diese kann aus einer Wellung bestehen, deren Wellenberge und Wellentäler wechselweise ineinandergreifen und auf Linien liegen, die die Achse der Spindel bzw. die Spitzen der gedachten Kegel dieser Flächen schneiden. Die Schrauben 14 verhindern ein gegenseitiges Verdrehen des Klemmringes 16 und der Klemmhülse 19, so daß der Eingriff der Wellenberge und Wellentäler aufrecht erhalten bleibt Die Strukturierung kann aber bspw. auch aus einer scharfkantigen Zahnung oder Zackung der Flächen 21, 22 bestehen.In order to bring about a secure clamping of the thread 6, the surfaces 21 and / or 22 of the clamping ring 16 or the clamping sleeve 19 according to the invention Structuring on. This can consist of a corrugation, its wave crests and Wave valleys alternately interlock and lie on lines that line the axis of the Cut the spindle or the tips of the imaginary cones of these surfaces. The Screws 14 prevent mutual rotation of the clamping ring 16 and Clamping sleeve 19, so that the engagement of the crests and troughs upright The structuring can, for example, also be made from a sharp-edged one Serration or serration of the surfaces 21, 22 exist.

    In manchen Fällen genügt es, nur eine der Flächen 21, 22 auf dem Klemmring 16 oder der Klemmhülse 19 mit der Strukturierung zu versehen und sie mit der glatten Fläche des jeweils anderen Klemmelementes zusammenwirken zu lassen, um das angestrebte Erhöhen des Reibwertes zu erreichen. In diesem Falle kann auf eine Verdrehsicherung verzichtet werden.In some cases, it is sufficient to have only one of the surfaces 21, 22 on the clamping ring 16 or to provide the clamping sleeve 19 with the structuring and it with the smooth surface the other clamping element to cooperate to achieve the desired To increase the coefficient of friction. In this case, an anti-rotation device can be used to be dispensed with.

    In vielen Fällen reicht auch ein Aufrauhen dieser Flächen aus, um die angestrebte sichere Klemmwirkung zu erreichen. Ein solches Aufrauhen kann bspw. durch Sandstrahlen erreicht werden und zu einer Strukturierung führen, die bspw. einer Nagelfeile ähnelt.In many cases, roughening these surfaces is sufficient to achieve the desired to achieve a secure clamping effect. Such roughening can, for example, by Sandblasting can be achieved and lead to a structuring, for example Nail file resembles.

    Wenn eines der Klemmelemente 16, 19 elastisch, bspw. aus nachgiebigem Kunststoff ausgebildet ist, kann es sich in eine Strukturierung anderen Klemmelementes einlegen, ohne selbst eine Strukturierung aufweisen zu müssen. Auch in diesem Falle erübrigt sich eine Verdrehsicherung.If one of the clamping elements 16, 19 is elastic, for example made of flexible plastic is formed, it can be structured in another clamping element insert without having to have a structure itself. In this case too there is no need for an anti-rotation device.
