Abstract

The feed of sliver (71) to a spinning machine (5) has an additional sliver guide (55') for the condensed sliver. The spinning assembly has a condenser (3) between the drawing unit (1) and the spinning machine (5). The additional guide (55'), below the condenser (3), is a deflection roller rotating on a pin, pref. of ceramic material, so that the sliver remains in contact with the condenser after it has passed through the clamping gap between a condensing section (31) and the locking roller (35). The additional guide (55') gives a path deflection of 10-40 deg .

Description

Die Erfindung betrifft eine Spinnmaschine nach dem Oberbegriff des unabhängigen Anspruchs.The invention relates to a spinning machine according to the preamble of the independent Claim.

Bei Spinnmaschinen insbesondere mit Verdichtungseinrichtungen besteht das Problem, dass der zwischen dem Streckwerk bzw. der Verdichtungseinrichtung und einer Aufwindevorrichtung gespannte Faden während des Betriebs der Maschine schlecht sichtbar ist.This exists in spinning machines, in particular with compression devices Problem that the between the drafting device or the compression device and a winder tensioned thread during the operation of the machine is poorly visible.

Dementsprechend besteht die Aufgabe der vorliegenden Erfin­ dung darin, diesem Nachteil abzuhelfen.Accordingly, the present inventor has the task to remedy this disadvantage.

Durch den Gegenstand des unabhängigen Anspruchs wird diese Aufgabe gelöst. Die Unteransprüche betreffen vorteilhafte Weiterbildungen.This object is achieved by the subject matter of the independent claim. The Subclaims relate to advantageous developments.

Als zusätzlicher Vorteil ergibt sich ein verbessertes Laufverhalten, das sich in einer Verringerung von Fadenbrüchen auswirkt.An additional advantage is an improved running behavior, which can be seen in a Reducing thread breaks affects.

Im folgenden wird die Erfindung anhand der Zeichnung im Detail beschrieben.The invention is described in detail below with reference to the drawing.

Fig. 1 zeigt eine schematische Darstellung einer Spinneinheit einer Spinnmaschine mit einer Verdichtungseinrichtung. Fig. 1 shows a schematic representation of a spinning unit of a spinning machine with a compression device.

Die Materialvorlage 7 besteht bei einer herkömmlichen Spinnmaschine entweder aus einer Kanne oder Vorgarnspule. Aus der Kanne wird ein Faserverband 71 (gestrichelt gezeichnet) dem Streckwerk 1 zugeführt. Im Falle einer Vorgarnspule wird Vorgarn vom Umfang der Spute abgezogen. Über eine Umlenkvorrichtung kommt der Faserver­ band, nämlich das Vorgarn oder das Faserband, in den Bereich eines Streckwerks 1. Das Streckwerk umfasst mehrere Paare von Lieferwalzen 11, vorzugsweise zum Teil mit Riemchen ausgestattet. Der Faserverband 71 wird zwischen dem ersten und zwei­ ten Lieferwalzenpaar 11 nur schwach und zwischen dem zweiten und nachfolgenden Walzenpaar 31 und 33 stark verzogen, wobei das Verzugsverhältnis insgesamt den Wert 100 übersteigen kann. Zwischen einer Klemmwalze 33 und einem Verdichtungs­ element 31 wird der verstreckte Faserverband geklemmt, und nachfolgend auf der Ver­ dichtungseinrichtung 3 verdichtet. Entlang der Verdichtungszone 31' kann eine Füh­ rung 39 bevorzugt in Form eines Schirmes den Faserverband an der Oberfläche des Verdichtungselements 31 begleiten. Abschliessend ist in der Verdichtungszone eine Sperrwalze 35 vorgesehen, welche an das Verdichtungselement angedrückt ist und so die Drehungserteilung von einer Spinneinrichtung 5 her entgegen der Materialflussrich­ tung begrenzt. Im Inneren des Verdichtungselements 31 befindet sich ein Saugelement 37, welches an eine Saugeinrichtung 4 angeschlossen ist.The material template 7 consists in a conventional spinning machine either from a can or roving spool. A fiber structure 71 (drawn in broken lines) is fed to the drafting device 1 from the jug. In the case of a roving spool, roving is subtracted from the circumference of the sput. About a deflection device comes the Faserver band, namely the roving or the sliver, in the area of a drafting device. 1 The drafting system comprises several pairs of delivery rollers 11 , preferably partially equipped with straps. The fiber structure 71 is only slightly warped between the first and two th pair of delivery rollers 11 and strongly warped between the second and subsequent pair of rollers 31 and 33 , and the overall draft ratio may exceed 100. The stretched fiber structure is clamped between a pinch roller 33 and a compression element 31 , and subsequently compressed on the compression device 3 . Along the compression zone 31 ', a guide 39, preferably in the form of an umbrella, can accompany the fiber structure on the surface of the compression element 31 . Finally, a blocking roller 35 is provided in the compression zone, which is pressed against the compression element and thus limits the rotation from a spinning device 5 against the material flow direction. Inside the compression element 31 is a suction element 37 , which is connected to a suction device 4 .

Zwischen dem Streckwerk 1 und der Spinneinrichtung 5 befindet sich ein Fadenführer 55, der im Falle einer Ringspinneinrichtung den Fadenballon des Garns 73 gemäss Fig. 1 nach oben hin begrenzt. Im unteren Bereich der Spinneinrichtung wird das Garn 73 mittels eines Läufers 53 auf einem Ring, der auf einem Ringrahmen 51 befestigt wird, durch die Drehung einer Spindel 59 mit Antrieb auf eine Garnpackung 75 aufge­ wickelt. Die Höhe der Garnpackung wird durch den Bewegungsbereich eines Ringrah­ menantriebs 57 bestimmt, der den Ringrahmen 51 in vertikaler Richtung gemäss Fig. 1 auf und ab versetzt.Between the drafting device 1 and the spinning device 5 there is a thread guide 55 which , in the case of a ring spinning device, limits the thread balloon of the yarn 73 according to FIG. 1 at the top. In the lower region of the spinning device, the yarn 73 is wound up by means of a runner 53 on a ring, which is fastened to a ring frame 51 , by rotating a spindle 59 with a drive on a package of yarn 75 . The height of the yarn package is determined by the range of motion of a ring frame drive 57 which moves the ring frame 51 up and down in the vertical direction according to FIG. 1.

Erfindungsgemäss wird zwischen der Verdichtungseinrichtung 3 und der Spinneinrich­ tung 5 bzw. dem Fadenführer 55 ein zusätzlicher Fadenführer 55' derart angeordnet, dass das Garn 73 unterhalb des Streckwerks 1 bzw. der Verdichtungseinrichtung 3 umgelenkt wird, bevor es in den Bereich der Spinneinrichtung 5 gelangt. Durch diese Umlenkung werden Garnschwingungen verhindert und somit die Sichtbarkeit des Fa­ dens oder Garns in der Spinnstelle verbessert. Der zusätzliche Fadenführer 55' kann beispielsweise als Keramikteil ausgeführt sein, das bevorzugt als drehbar gelagerte Rolle auf einer Achse sitzt, an dessen Umfang das Garn 73 läuft und die Rolle in Dre­ hung versetzt. Vorzugsweise wird die Rolle mit einer V-förmigen Lauffläche für das Garn 73 ausgeführt. According to the invention between the compression means 3 and the Spinneinrich tung 5 and the yarn guide 55, an additional thread guide 55 'are arranged such that the yarn is deflected 73 below the drafting unit 1 and the compression means 3, before it reaches the region of the spinning device. 5 This deflection prevents yarn vibrations and thus improves the visibility of the thread or yarn in the spinning station. The additional thread guide 55 'can for example be designed as a ceramic part, which preferably sits as a rotatably mounted roller on an axis, on the circumference of which the yarn 73 runs and the roller is rotated. The roll is preferably designed with a V-shaped running surface for the yarn 73 .

Wie aus Fig. 1 ersichtlich ist, wird der zusätzliche Fadenführer 55' so angeordnet, dass das Garn 73 unterhalb des Verdichtungselements 31 nach Verlassen des Klemmspal­ tes zwischen dem Verdichtungselement 31 und der Sperrwalze 35 noch am Umfang des Verdichtungselements 31 bzw. der perforierten Walze verbleibt. Der Fadenführer 55' wird zwischen der Verdichtungseinrichtung 3 und der Spinneinrichtung 5 bevorzugt so angeordnet, dass sich ein Umlenkwinkel zwischen 10° und 40° infolge des Faden­ führers 55' ergibt. As is apparent from Fig. 1, the additional thread guide is positioned 55 'so that the yarn 73 below the compacting element 31 after leaving the Klemmspal tes between the compression member 31 and the locking roller 35 nor the circumference of the compression member 31 and the perforated roll remains . The thread guide 55 'is preferably arranged between the compression device 3 and the spinning device 5 such that there is a deflection angle between 10 ° and 40 ° as a result of the thread guide 55 '.
