Abstract

A device for compressing a drafted assembly of fibers (4) is arranged downstream from a pair of delivery rollers (7) in the drafting equipment (1) of a spinning machine. The compression area (11) comprises a suction roller (15) which lies adjacent to two driven rollers (8), (19) forming two clamping points (12), (13) for clamping the assembly of fibers. A suction slot (18) is located inside the suction roller between the clamping points. Said slot defines the length of the compression area. The first clamping point (12) in the direction of conveyance of the assembly of fibers is formed with a driven lower roller (8) belonging to the pair of delivery rollers (8,9) in the drafting equipment, whereby the assembly of fibers to be compressed is guided in a continuously effective manner from the drawing area to the end of the compressing area

Description

Vorrichtung in einer Spinnmaschine zum Verdichten eines Faserverbandes Device in a spinning machine for compacting a fiber structure
Die Erfindung betrifft eine Vorrichtung in einer Spinnmaschine zum Verdichten eines Faserverbandes, mit einer einem Ausgangswalzenpaar eines Streckwerks folgenden Verdichtungszone, die eine Saugwalze enthält, welche unter Bilden zweier den Faserverband klemmender Klemmstellen an zwei angetriebenen Walzen anliegt und in ihrem Innern einen zwischen den Klemmstellen befindlichen und dadurch die Länge der Verdichtungszone definierenden Saugschlitz enthält.The invention relates to a device in a spinning machine for compacting a fiber structure, with a compression zone following an output roller pair of a drafting system, which contains a suction roller, which rests on two driven rollers to form the fiber structure clamping nip points and one inside and one located between the nip points thereby containing the length of the compression zone defining the compression zone.
Wenn einem verstreckten Faserverband in unmittelbarem Anschluss an das Ausgangswalzenpaar des Streckwerks der Spinndrall erteilt wird, dann entsteht an der Klemmlinie des Ausgangswalzenpaares ein so genanntes Spinndreieck. Dies rührt daher, dass der verstreckte Faserverband mit einer bestimmten Breite das Streckwerk verlässt und zu einem Faden relativ kleinen Durchmessers zusammengedreht wird. Das Spinndreieck enthält Randfasern, die nicht ordnungsgemäß in den verdrehten Faden eingebunden werden und somit wenig oder nichts zur Festigkeit des ersponnenen Fadens beitragen. Man ist daher in jüngerer Zeit dazu übergegangen, der Verzugszone des Streckwerks eine so genannte Verdichtungszone nachzuordnen, die ihrerseits von einer Klemmstelle auslaufseitig begrenzt wird. Erst danach wird dem Faden die Spinndrehung erteilt. In der Verdichtungszone werden die Fasern gebündelt oder verdichtet, wodurch der Faserverband beim Verlassen der letzten Klemmstelle so schmal ist, dass das gefürchtete Spinndreieck nicht mehr entsteht. Der ersponnene Faden wird dann gleichmäßiger und fester und weniger haarig.If a stretched fiber structure is given the spin twist immediately after the exit roller pair of the drafting system, a so-called spin triangle is created at the clamping line of the exit roller pair. This is due to the fact that the stretched fiber structure leaves the drafting system with a certain width and is twisted into a thread of relatively small diameter. The spinning triangle contains edge fibers that are not properly incorporated into the twisted thread and thus contribute little or nothing to the strength of the spun thread. It has therefore recently started to assign a so-called compression zone to the draft zone of the drafting system, which in turn is delimited on the outlet side by a clamping point. Only then is the thread spun. The fibers are bundled or compacted in the compression zone, which means that the fiber structure is so narrow when leaving the last nip point that the dreaded spinner triangle no longer arises. The spun thread then becomes more even and firmer and less hairy.
Eine eine Verdichtungszone enthaltende Vorrichtung der eingangs genannten Art ist durch die DE 198 15 052 A1 , Figur 2, Stand der Technik. Bei dieser bekannten Vorrichtung muss der verstreckte Faserverband, ohne unterstützt zu sein, eine gewisse Wegstrecke zurücklegen, bevor er auf die Oberfläche der der Verdichtungszone zugehörigen Saugwalze gelangt. Der bis zu seiner endgültigen Feinheit verstreckte und noch ohne jegliche Spinndrehung versehene Faserverband ist jedoch überaus zerbrechlich, so dass die Gefahr von Fehlverzügen oder gar von einem Bruch des Faserverbandes besteht.A device of the type mentioned at the outset containing a compression zone is state of the art by DE 198 15 052 A1, FIG. 2. In this known device, the stretched fiber structure has to travel a certain distance, without being supported, before it reaches the surface of the suction roll belonging to the compression zone. The fiber structure, stretched to its final fineness and still without any spinning twist, is extremely fragile, so that there is a risk of incorrect drawing or even breakage of the fiber structure.
Der Erfindung liegt die Aufgabe zu Grunde, die Vorrichtung der eingangs genannten Art dahingehend zu verbessern, dass die Gefahr von Fehlverzügen und Faserverbandbrüchen vermieden wird.The invention is based on the object of improving the device of the type mentioned at the outset in such a way that the risk of incorrect drawing and fiber breakage is avoided.
Die Aufgabe wird dadurch gelöst, dass die in Transportrichtung des Faserverbandes erste Klemmstelle mit der angetriebenen Unterwalze des Ausgangswalzenpaares des Streckwerks gebildet ist.The object is achieved in that the first clamping point in the transport direction of the fiber structure is formed with the driven lower roller of the pair of output rollers of the drafting system.
Auf Grund dieser Ausgestaltung liegt der verstreckte und noch nicht verdrehte Faserverband vom Ende der Verzugszone bis zum Ende der Verdichtungszone ständig am Umfang einer Walze an. Zunächst ist dies ein Teil des Umfanges der Ausgangsunterwalze, und zwar bis zur ersten Klemmstelle, an welcher die Saugwalze an der Unterwalze anliegt. Anschließend umschlingt der Faserverband in der Verdichtungszone den Umfang der Saugwalze und zwar bis zur zweiten Klemmstelle, nach welcher dem nunmehr verdichteten Faserverband der Spinndrall erteilt wird. Der Faserverband ist somit auf der gesamten Wegstrecke, längs welcher er zerbrechlich ist, außerordentlich gut geführt.Because of this configuration, the stretched and not yet twisted fiber structure is constantly in contact with the circumference of a roller from the end of the draft zone to the end of the compression zone. First of all, this is part of the circumference of the output lower roller, up to the first nip point at which the suction roller rests on the lower roller. The fiber structure then wraps around the circumference of the suction roll in the compression zone, namely up to the second nip point, after which the now compacted fiber structure is given the spin twist. The fiber structure is therefore extremely well guided along the entire path along which it is fragile.
Weitere Vorteile und Merkmale der Erfindung ergeben sich aus den Unteransprüchen und der nachfolgenden Beschreibung eines Ausführungsbeispiels.Further advantages and features of the invention result from the subclaims and the following description of an exemplary embodiment.
Es zeigen:Show it:
Figur 1 eine teilweise geschnittene Seitenansicht auf eine Vorrichtung nach der Erfindung, Figur 2 eine Ansicht in Richtung des Pfeiles II auf die Figur 1.FIG. 1 shows a partially sectioned side view of a device according to the invention, Figure 2 is a view in the direction of arrow II on Figure 1.
Die in Figuren 1 und 2 dargestellte Vorrichtung 3 ist Bestandteil einer Spinnstelle einer Spinnmaschine, insbesondere einer Ringspinnmaschine. Die Vorrichtung 3 folgt einem Streckwerk 1 , in welcher ein Faserband oder Vorgarn 2 verstreckt wird, und dient dem Zweck, den verstreckten, jedoch noch spinndrehungsfreien Faserverband 4 durch seitliches Zusammenfassen seiner Fasern zu verdichten.The device 3 shown in Figures 1 and 2 is part of a spinning station of a spinning machine, in particular a ring spinning machine. The device 3 follows a drafting device 1, in which a sliver or roving 2 is drawn, and serves the purpose of compressing the drawn, but still spinning-free fiber structure 4 by laterally combining its fibers.
Das Streckwerk 1 enthält in bekannter Weise ein Eingangswalzenpaar 5, ein Riemchenwalzenpaar 6 und ein Ausgangswalzenpaar 7. Letzteres besteht aus einer angetriebenen Unterwalze 8 sowie einer dagegen angedrückten Druckwalze 9. Im Streckwerk 1 wird in bekannter Weise das Faserband oder Vorgarn 2 in Transportrichtung A bis zur gewünschten Feinheit verstreckt. An der Ausgangsklemmlinie 10 des Ausgangswalzenpaares 7 ist die Verzugszone des Streckwerks 1 beendet.The drafting system 1 contains, in a known manner, an input roller pair 5, an apron roller pair 6 and an output roller pair 7. The latter consists of a driven lower roller 8 and a pressure roller 9 pressed against it. In the drafting system 1, the sliver or roving 2 is transported in the transport direction A up to stretched the desired fineness. At the exit nip line 10 of the exit roller pair 7, the draft zone of the drafting unit 1 is ended.
In einer dem Streckwerk 1 nachfolgenden Verdichtungszone 11 wird der verstreckte, jedoch noch spinndrehungsfreie Faserverband 4 verdichtet, bevor ihm später der eigentlich Spinndrall erteilt wird. Die Verdichtungszone 11 ist einlaufseitig durch eine erste Klemmstelle 12 und auslaufseitig durch eine zweite Klemmstelle 13 begrenzt. Die zweite Klemmstelle 13 dient beim anschließenden Aufbringen des Spinndralls auf den zu erspinnenden Faden 14 als Drallstopp, damit die Spinndrehung nicht bis in die Verdichtungszone 11 zurückläuft. Wenn der Faden 14 in Lieferrichtung B einem nicht dargestellten Drallorgan, beispielsweise einer Ringspindel zugeführt wird, entsteht an der zweiten Klemmstelle 13 kein Spinndreieck.In a compression zone 11 following the drafting unit 1, the drawn fiber assembly 4, which is still free of spinning twist, is compressed before the actual spin twist is given to it later. The compression zone 11 is delimited on the inlet side by a first clamping point 12 and on the outlet side by a second clamping point 13. The second clamping point 13 is used during the subsequent application of the spin twist to the thread 14 to be spun as a twist stop, so that the spin rotation does not run back into the compression zone 11. If the thread 14 is fed in the direction of delivery B to a swirl element, not shown, for example an annular spindle, no spinning triangle is formed at the second clamping point 13.
Die Vorrichtung 3 zum Verdichten des Faserverbandes 4 enthält eine Saugwalze 15, deren Umfang perforiert ist, so dass der Mantel der Saugwalze 15 in bekannter Weise über eine gewisse Arbeitsbreite luftdurchlässig ist. Die Saugwalze 15 ist in nicht dargestellter Weise auf einem stationären Saugrohr 16 gelagert, auf welchem wiederum ein Saugeinsatz 17 verstellbar angeordnet ist. Der Saugeinsatz 17 enthält einen Saugschlitz 18, der sich im Wesentlichen in Transportrichtung A erstreckt und der die Länge der Verdichtungszone 11 definiert. Wie aus Figur 2 zur ersehen ist, ist der Saugschlitz 18 gegenüber der Bewegungsrichtung des Umfanges der Saugwalze 15 leicht schräg angeordnet, wodurch der zu verdichtende Faserverband 4 längs einer Kante des Saugschlitzes 18 entlang läuft und dabei während des Verdichtens einen leichten Falschdrall erhält. Die Saugwalze 15 liegt sowohl an der angetriebenen Unterwalze 8 des Ausgangswalzenpaares 7 als auch an einer weiteren angetriebenen Unterwalze 19 an, wodurch die beiden genannten Klemmstellen 12 und 13 gebildet werden. Da die Unterwalzen 8 und 19 getriebemäßig miteinander verbunden sind, weisen sie die gleichen Umfangsgeschwindigkeiten auf. Die Unterwalzen 8 und 19 sind jeweils mit einem elastischen Belag 20 und 21 versehen, was wegen der metallenen Oberfläche der Saugwalze 15 zweckmäßig ist.The device 3 for compacting the fiber structure 4 contains a suction roller 15, the periphery of which is perforated, so that the jacket of the suction roller 15 is air-permeable in a known manner over a certain working width. The suction roller 15 is mounted in a manner not shown on a stationary suction tube 16, on which in turn a suction insert 17 is arranged to be adjustable. The suction insert 17 contains a suction slot 18 which extends essentially in the transport direction A and which defines the length of the compression zone 11. As can be seen from Figure 2, the suction slot 18 is arranged slightly obliquely with respect to the direction of movement of the circumference of the suction roller 15, as a result of which the fiber structure 4 to be compressed runs along an edge of the suction slot 18 and thereby receives a slight false twist during the compression. The suction roll 15 bears both against the driven lower roll 8 of the pair of output rolls 7 and against a further driven lower roll 19, as a result of which the two nip points 12 and 13 mentioned are formed. Since the lower rollers 8 and 19 are connected to one another in terms of gears, they have the same peripheral speeds. The lower rollers 8 and 19 are each provided with an elastic covering 20 and 21, which is expedient because of the metallic surface of the suction roller 15.
Wie aus Figur 1 ersichtlich, ist die Unterwalze 8 des Ausgangswalzenpaares 7 um nahezu 90° ihres Umfanges vom Faserverband 4 umschlungen. Diese Umschlingung sollte wenigstens 45° betragen. Im Anschluss daran umschlingt der zu verdichtende Faserverband 4 die Saugwalze 15 um wenigstens 90°. Der Faserverband 4 liegt somit nicht nur zwischen den Klemmstelle 12 und 13 der Verdichtungszone 11, sondern bereits ab der Ausgangsklemmlinie 10 ständig an einer unterstützenden Fläche an. Der Faserverband 4 ist somit nach seinem Verstrecken bis zum Erteilen des Spinndralls durchgängig bestens geführt. As can be seen from FIG. 1, the lower roller 8 of the pair of output rollers 7 is wrapped by the fiber structure 4 by almost 90 ° of its circumference. This loop should be at least 45 °. Subsequently, the fiber structure 4 to be compressed wraps around the suction roll 15 by at least 90 °. The fiber structure 4 is therefore not only in contact with the nip point 12 and 13 of the compression zone 11, but already from the initial nip line 10 on a supporting surface. The fiber structure 4 is thus consistently well guided after it is stretched until the spinning twist is given.
