Description

Die Erfindung betrifft einen Luntenverdichter in Streckwerken von Spinnmaschinen, wobei das Streckwerk ein von einem Riemchenpaar und einem diesem nachgeordneten Walzenpaar gebildetes Streckfeld und einen Trag- und Belastungsarm aufweist und wobei der Luntenverdichter pendelnd an einer am Trag- und Belastungsarm gehalterten Lagerstange gelagert ist und sein Verdichtungstrichter in dem Zwickel am Einlauf des nachgeordneten Walzenpaares liegt.The invention relates to a sliver compressor in drafting systems of spinning machines, the drafting system being one of a pair of straps and a roller pair arranged after this Stretching field and a support and load arm and where the fuse compressor oscillates on one of the carrying and loading arms supported bearing rod is stored and its compression funnel in the gusset at the inlet of the downstream pair of rollers lies.

Ein derartiger Luntenverdichter ist bspw. aus der DE 1.825.759 U bekannt. Die beiden, in ihrem Zusammenwirken den Verdichtungstrichter bildenden Elemente desselben sind über je einen Steg mit je einer Lagerbüchse verbunden, die auf der Lagerstange schwenkbar ist. Damit sich die Verdichtungstrichter dem jeweiligen Laufpfad der in aller Regel changierenden Lunte folgen können, ist die Lagerstange selbst oder sind Lagerhülsen, auf denen die Lagerbüchsen schwenkbar, aber axial nicht verschiebbar sind, in gewissem Ausmaß auch axial auf der Lagerstange verschiebbar.Such a sliver compressor is, for example, from DE 1.825.759 U known. The two, in their interaction, the compression funnel forming elements of the same are each over a web each connected to a bearing bush on the bearing rod is pivotable. So that the compression funnel suits the respective Follow the path of the generally changing fuse can, is the bearing rod itself or are bearing sleeves on which the bearing bushes can pivot, but not axially are, to a certain extent, also axially displaceable on the bearing rod.

Die die Verdichtungstrichter und ihre Lagerbüchsen verbindenden Stege erstrecken sich zwischen dem Oberriemchen und der Umfangsfläche der Oberwalze des Riemchenpaares nach oben. Zwischen diesem Oberriemchen und dieser Oberwalze muß daher ein Abstand für den Durchtritt der Stege vorgesehen sein. Dies hat jedoch den Nachteil, daß der Abstand zwischen dem Auslauf des Riemchenpaares und der Klemmlinie des nachgeordneten Walzenpaares entsprechend vergrößert werden muß. Dadurch wird die Führung der Fasern in dem in aller Regel das Hauptverzugsfeld bildenden Streckfeld des Streckwerkes vermindert und damit die Qualität des erzeugten Garnes beeinträchtigt.The connecting the compression funnels and their bearing bushes Webs extend between the top strap and the peripheral surface the top roller of the strappy pair upwards. Between this Upper apron and this top roller must therefore be a distance for the passage of the webs may be provided. However, this has the Disadvantage that the distance between the outlet of the pair of straps and the clamping line of the downstream roller pair accordingly must be enlarged. This will lead the Fibers in what is usually the main warping field The drafting field of the drafting system is reduced and thus the quality of the yarn produced is impaired.

Der Erfindung war demgemäß die Aufgabe gestellt, den Verdichtungstrichter eines Luntenverdichters im Streckfeld eines Streckwerkes so zu haltern, daß kein Vergrößern des Abstandes zwischen dem Auslauf des Riemchenpaares und der Klemmlinie des nachgeordneten Walzenpaares erforderlich wird.The object of the invention was accordingly the compression funnel of a fuse compressor in the draw field of a To keep the drafting system so that the distance does not increase between the outlet of the strappy pair and the clamping line of the downstream roller pair is required.

Sie löst diese Aufgabe dadurch, daß der Haltearm das Oberriemchen und/oder die Oberwalze des nachgeordneten Walzenpaares seitlich umgreift.It achieves this task by the fact that the holding arm laterally engages around the top strap and / or the top roller of the downstream pair of rollers.

Aus der DE 1.785.119 U ist es zwar bekannt, einen einstückigen Verdichtungstrichter mittels eines U-förmigen Haltebügels aus Draht am Käfig des Oberriemchens zu haltern, wobei die beiden Schenkel dieses Haltebügels sich seitlich des Oberriemchens nach oben erstrecken. Es handelt sich hierbei aber nicht um einen Luntenverdichter, der pendelnd an einer parallel zu den Streckwalzen verlaufenden Haltestange gelagert ist.From DE 1.785.119 U it is known to be a one-piece Compression hopper using a U-shaped bracket To hold wire on the cage of the top strappy, taking the two Leg of this bracket is laterally after the top strap extend above. But this is not one Sliver compactor, oscillating on one parallel to the stretching rollers extending support rod is stored.

Die Verdichtungstrichter der bevorzugten Art der eingangs genannten Luntenverdichter bestehen aus zwei, unabhängig voneinander pendelnd gehalterten Teilstücken, die im Zusammenwirken den Luntentrichter bilden. In manchen Fällen sind die Verdichtungstrichter aber auch einstückig ausgebildet.
Im ersteren Falle weist jedes Teilstück eines Verdichtungstrichters einen Haltearm auf, der dann das Oberriemchen und/oder die Oberwalze des nachgeordneten Walzenpaares jeweils auf der Seite umgreift, auf der das Teilstück des Verdichtungstrichters in Bezug auf die zu verdichtende Lunte angeordnet ist.
The compression funnels of the preferred type of the sliver compressors mentioned at the outset consist of two parts which are held in an oscillating manner and which, in cooperation, form the sliver funnel. In some cases, the compression funnels are also made in one piece.
In the former case, each section of a compaction funnel has a holding arm, which then engages around the top apron and / or the top roller of the downstream roller pair on the side on which the section of the compaction funnel is arranged with respect to the fuse to be compressed.

Im zweiten Falle ist zur Verwirklichung der Erfindung nur ein das Oberriemchen und/oder die Oberwalze des nachgeordneten Walzenpaares seitlich umgreifender Haltearm erforderlich. Dieser Haltearm ist bei dem die Regel darstellenden Einsatz von Oberwalzenzwillingen und Zwillingsriemchen vorteilhafterweise auf der freien Seite dieser Zwillingsorgane angeordnet. Es gibt dann rechtsseitig umgreifende und linksseitig umgreifende Haltearme.In the second case, only one is to implement the invention the top strap and / or the top roller of the downstream pair of rollers lateral support arm required. This The holding arm is the rule for the use of top roller twins and twin straps advantageously the free side of these twin organs. Then there is right-hand gripping and left-hand gripping arms.

In weiterer Ausgestaltung der Erfindung ist bei einstückigen Verdichtungstrichtern mit einer oder zwei Trichteröffnungen, bei denen die Trichteröffnung auf ihrer Oberseite geschlossen ist und nur unten einen Einfädelschlitz für die Faserlunte aufweist, vorgesehen, daß der Verdichtungstrichter auf seiner Oberseite in eine dünne Trennwand übergeht, die sich in den Zwischenraum zwischen dem Oberriemchen und der Ausgangsoberwalze erstreckt. Diese Trennwand verhindert, daß die Faserlunte den oberen Trichterrand übersteigt und unter Umgehen des Verdichtungstrichters zum Ausgangswalzenpaar läuft. Diese Gefahr ist ersichtlich bei zweigeteilten Verdichtungstrichtern nicht gegeben.In a further embodiment of the invention is in one piece Compression funnels with one or two funnel openings, at which the top of the funnel opening is closed and only has a threading slit for the fiber sliver at the bottom, provided that the compression funnel on its top in a thin partition merges into the space in between extends between the top apron and the top output roller. This partition prevents the fiber sliver from reaching the top edge of the funnel exceeds and bypassing the compaction funnel runs to the pair of output rollers. This danger can be seen at two-parted funnel not given.

Das aus Fig. 1 ersichtliche Streckwerk ist von geläufiger Bauart, so daß hier nur die wesentlichen und für das Verständnis der Erfindung wichtigen Teile benannt und beschrieben sind. Das Streckwerk weist drei Walzenpaare 1, 2 und 3 mit über die Länge des Streckwerkes durchgehenden, angetriebenen Unterwalzen 4 und Zwillings-Oberwalzen 5 auf. Die Unterwalze 4 des Ausgangswalzenpaares 3 ist unmittelbar, die Unterwalzen der anderen Walzenpaare 1 und 2 sind über Lagerschlitten 6 bzw. 7 in Stanzen 8 gelagert. An den Stanzen 8 sind über eine Tragstange 9 auch Trag- und Belastungsarme 10 aufklappbar gehaltert, welche die hier nicht näher dargestellten Führungs- und Belastungsorgane der Oberwalzen 5 der Walzenpaare 1 bis 3 enthalten.1 is of a common design, so that here only the essential and for understanding important parts of the invention are named and described. The The drafting system has three pairs of rollers 1, 2 and 3 along the length of the drafting unit, driven lower rollers 4 and Twin top rollers 5. The lower roller 4 of the pair of output rollers 3 is immediate, the lower rolls of the other pairs of rolls 1 and 2 are stored in punch 8 via bearing carriages 6 and 7, respectively. On the punches 8 are also carrying a support rod 9 and load arms 10 hinged, which the here Management and stress organs of the Top rollers 5 of the roller pairs 1 to 3 contain.

In den durch die Walzenpaare 2 und 3 gebildeten Hauptverzugsfeidern des Streckwerkes sind sowohl Doppelriemchenaggregate mit je einem Unterriemchen 11 und je einem Oberriemchen 12 als auch Luntenverdichter 13 mit Verdichtungstrichtern 14 angeordnet. Diese Verdichtungstrichter 14 liegen in den einlaufseitigen Zwickeln zwischen den Walzen 4 und 5 des Ausgangswalzenpaares 3 an den Walzen an. Die Verdichtungstrichter 14 sind jeweils mittels mindestens eines Haltearmes 15 und einer Lagerbüchse 16 an einer parallel zu den Walzen des Streckwerkes liegenden Haltestange 17 pendelnd gelagert.In the main warpage formed by the pairs of rollers 2 and 3 of the drafting system are both with double apron units one lower strap 11 and one upper strap 12 as well Match compressor 13 arranged with compression funnels 14. These compression funnels 14 are in the inlet side Gusset between the rollers 4 and 5 of the pair of output rollers 3 on the rollers. The compression funnels 14 are each means at least one holding arm 15 and a bearing bush 16 a handrail parallel to the rollers of the drafting system 17 oscillating.

Wie bekannt, dienen die Riemchenaggregate dazu, die Fasern im Verzugsfeld bis möglichst nahe an die Klemmlinie des nachgeordneten Walzenpaares 3 heran zu führen. Um den Zwischenraum zwischen dem Oberriemchen 12 und der Oberwalze 5 des Ausgangswalzenpaares 3 nicht für den Durchtritt dieses Haltearmes 15 und damit den Abstand zwischen der Mündung des Riemchenaggregates und der Klemmlinie des Ausgangswalzenpaares vergrößern zu müssen, ist erfindungsgemäß vorgesehen, diesen Haltearm wie dargestellt seitlich neben der Oberwalze 5 und/oder wie nicht näher dargestellt seitlich neben dem Oberriemchen 12 verlaufen zu lassen.
Wie aus den Fig. 2 und 3 erkennbar, sind die Haltearme 15 zu diesem Zweck winkelartig ausgebildet.
As is known, the apron units serve to bring the fibers in the draft zone as close as possible to the clamping line of the downstream pair of rollers 3. In order not to have to increase the space between the upper apron 12 and the upper roller 5 of the output roller pair 3 for the passage of this holding arm 15 and thus the distance between the mouth of the apron assembly and the clamping line of the output roller pair, it is provided according to the invention that this holding arm is shown laterally next to the Let the upper roller 5 and / or, as not shown in detail, run laterally next to the top strap 12.
As can be seen from FIGS. 2 and 3, the holding arms 15 are of an angular design for this purpose.

In der bevorzugten, da wirksameren, Ausführungsform von Luntenführern der Fig. 2 bestehen deren Verdichtungstrichter 14 aus jeweils zwei, unabhängig voneinander pendelnd gehalterten Trichterelementen 18 und 19, die zusammenwirkend den Verdichtungstrichter bilden. Jedes dieser Trichterelemente 18, 19 ist über einen Haltearm 15 bzw. 15' und eine Lagerbüchse 16, 16' auf der Lagerstange 17 gelagert. Klemmscheiben 20 begrenzen die axiale Verschiebbarkeit der Büchsen 16, 16' auf der Lagerstange 17. Jeder Haltearm 15, 15' besteht aus einem ersten, zu den Walzen parallelen, im Zwickel des Ausgangswalzenpaares 3 liegenden Steg 21 und einem diesen Steg mit der zugeordneten Lagerbüchse 16, 16' verbindenden zweiten Steg 22, der erfindungsgemäß seitlich neben der Oberwalze 5 oder dem Oberriemchen 12 liegt.In the preferred, since more effective, embodiment of sliver guides 2 consist of their compression funnels 14 two funnel elements, each swinging independently 18 and 19 interacting with the compression hopper form. Each of these funnel elements 18, 19 is over a holding arm 15 and 15 'and a bearing bush 16, 16' on the Bearing rod 17 stored. Clamping discs 20 limit the axial Movability of the sleeves 16, 16 'on the bearing rod 17. Everyone Holding arm 15, 15 'consists of a first, parallel to the rollers, in the gusset of the pair of output rollers 3 lying web 21 and a web with the associated bearing bush 16, 16 'connecting second web 22, the side according to the invention is next to the top roller 5 or the top strap 12.

Wie aus Fig. 1 erkennbar, sind die Stege 22 der Haltearme 15, 15' gekrümmt und liegen seitlich neben der Oberwalze 5 des Ausgangswalzenpaares 3. Diese Stege 22 können jedoch ebenso gut gerade oder auch entgegengesetzt gekrümmt sein, wodurch sie neben das Oberriemchen 12 zu liegen kommen.1, the webs 22 of the holding arms 15, 15 'curved and lie laterally next to the top roller 5 of the pair of output rollers 3. However, these webs 22 can just as well be straight or also be curved in the opposite direction, which makes them next to the top strap 12 come to rest.

In der Ausführungsform der Fig. 3 sind die Verdichtungstrichter 14 einstückig ausgebildet und nach unten offen. In diesem Falle genügt zum Haltern eines Verdichtungstrichters jeweils ein Haltearm 15, der im übrigen entsprechend der Figur 2 ausgebildet sein kann.In the embodiment of FIG. 3, the compression funnels are 14 formed in one piece and open at the bottom. In this case One arm is sufficient to hold a compression funnel 15, which is otherwise designed according to Figure 2 can be.

Fig. 5 zeigt eine Ausführungsform des erfindungsgemäß gehalterten Verdichtungstrichters in einem Streckwerk für das Herstellen von Core-Garn. Unter Core-Garn wird ein Garn verstanden, bei dem ein zugeführter, fertiger Kernfaden - meist ein synthetischer Endlosfaden - mit Fasern umsponnen wird. Der Kernfaden wird der im Streckwerk verstreckten Faserlunte vor dem Ausgangswalzenpaar zugeführt.Fig. 5 shows an embodiment of the one according to the invention Compression funnel in a drafting system for manufacturing of core yarn. Core yarn means a yarn in which a supplied, finished core thread - usually a synthetic one Continuous thread - is wound with fibers. The core thread is the fiber sliver stretched in the drafting system in front of the pair of exit rollers fed.

Wie aus Fig. 5 erkennbar, weisen die einstückigen Luntenverdichter 13 je zwei Haltearme 15, 15' auf, die an die auf der Haltestange 17 verschiebbar geführten Lagerbüchsen 16, 16' angeformt sind. Zwischen den Lagerbüchsen 16, 16' ist eine Nutrolle 25 auf der Haltestange 17 drehbar gelagert.As can be seen from Fig. 5, the one-piece fuse compressors 13 each two holding arms 15, 15 'on the on the Holding rod 17 slidably guided bushings 16, 16 'formed are. Between the bearing bushes 16, 16 'is a grooved roller 25 rotatably mounted on the support rod 17.

Beim Lauf des Streckwerkes werden die Verdichtungstrichter 14 der beiden Luntentrichter 13 durch die Faserlunte in der dieser erteilten Changierung über einen Teil der Breite des geriffelten Bereiches der Unterwalze 4 mitgenommen. In dieser Changierbewegung wird auch die Nutrolle 25 mitgenommen, so daß der zulaufende Kernfaden stets auf die Faserlunte geführt wird.When the drafting system runs, the compression funnels 14 of the two sliver funnels 13 through the fiber sliver in the latter issued oscillation over part of the width of the corrugated Area of the lower roller 4 entrained. In this traversing movement the grooved roller 25 is also taken along, so that the incoming Core thread is always guided on the fiber sliver.

Es versteht sich, daß der Haltearm 15 eines der beiden Luntenverdichter 13 auch auf der Innenseite der Zwillingsoberwalze gegen den Belastungsarm 10 zu angeordnet sein kann, wenn die Platzverhältnisse dies zulassen. Es liegt dann der Haltearm des einen Verdichtungstrichters 14 auf der Außenseite, der des anderen Verdichtungstrichters auf der Innenseite einer Zwillingsoberwalze 5. Diese Ausführungsform hat den Vorteil, daß die Lunterverdichter 13 gleich ausgeführt sein können.It is understood that the holding arm 15 is one of the two sliver compressors 13 also against the inside of the twin top roller the loading arm 10 can be arranged when the Space allow this. It is then the arm of the a compression funnel 14 on the outside, that of the other Compaction funnel on the inside of a twin top roller 5. This embodiment has the advantage that the sub-compressor 13 can be executed the same.

Zum In-Betrieb-Nehmen des Streckwerkes werden bei aufgeklappten Trag- und Belastungsarmen 10 die Faserlunten auf die Unterwalzen 4 gelegt und dann die Trag- und Belastungsarme abgeklappt und verriegelt. Bei diesem Abklappen der Trag- und Belastungsarme senken sich auch die Verdichtungstrichter 14 sowohl der zweiteiligen als auch der einteiligen Ausführungsform mit ihren unteren, gegen die Mitte ansteigenden Leitkanten 23 über die Faserlunten und führen diese in den mittigen Leitkanal der Verdichtungstrichter 14.To put the drafting system into operation, open the Carrying and loading arms 10 the fiber lunches on the lower rollers 4 placed and then the support and load arms folded down and locked. With this folding of the support and load arms also lower the compression funnels 14 of the two-part as well as the one-piece embodiment with their lower, rising towards the center leading edges 23 over the fiber slats and guide them into the central guide channel of the compression funnel 14th

Unter Spinnzwirnen wird ein Spinnverfahren verstanden, bei dem zwei Faserlunten parallel nebeneinander durch eine Arbeitsstelle eines Streckwerkes laufen und am Ausgang des Streckwerkes unter Wirkung der durch die Spindel erteilten Drehung zu einem Garn vereinigt werden. Das so erzeugte Garn ist zwirnähnlich und wird daher auch als Scheinzwirn bezeichnet.Fig. 4 shows an embodiment of the held according to the invention Compression funnel in a drafting device for spinning. Spinning threads is understood to be a spinning process in which two fiber lunches in parallel next to each other through a job of a drafting system run and at the exit of the drafting system under the effect of the rotation given by the spindle be combined into one yarn. The yarn produced in this way is like a thread and is therefore also known as a false thread.

Um die beiden nebeneinander durch die Arbeitsstelle eines Streckwerkes laufenden Faserlunten je für sich verdichten zu können, weist der Luntenverdichter 13 in der Ausführungsform der Fig. 4 zwei Verdichtungstrichter 14 und 14' auf, in denen jeweils eine der beiden Faserlunten geführt ist und verdichtet wird. Da der durch die Einlauftrichter des Streckwerkes bestimmte gegenseitige Abstand der beiden Faserlunten gleich bleibt, können die beiden Verdichtungstrichter 14, 14' mit dem durch den Einlauftrichter vorgegebenen gegenseitigen Abstand in einem gemeinsamen Verdichtungskörper angeordnet sein.To the two next to each other through the workplace The drafting system running fiber slits each compress themselves can, the fuse compressor 13 in the embodiment of the Fig. 4 two compression funnels 14 and 14 ', in each one of the two fibers is guided and compressed becomes. Because the determined by the intake funnel of the drafting system mutual distance between the two fiber lunches equal remains, the two compression funnels 14, 14 'with the mutual distance predetermined by the inlet funnel be arranged a common compression body.

In der Ausführungsform der Fig. 4 ist eine weitere Ausgestaltung des erfindungsgemäßen Luntenverdichters dargestellt. Er weist in dem zwischen dem Oberriemchen 12 und der Ausgangsoberwalze 5 liegenden Bereich eine dünne, gegebenenfalls nur folienartige Trennwand 24 auf, die an die Oberkante des Verdichtungstrichters 14 angeformt ist. Sie kann darüber hinaus auch mit dem Haltearm 15 und der Lagerbüchse 16 verbunden sein und erhöht hierdurch - wenn sie selbst steif ist - die Steifigkeit des Luntenverdichters 13.4 is a further embodiment of the sliver compressor according to the invention. He points in between the top apron 12 and the top output roller 5 lying area a thin, possibly only film-like Partition 24 on the top of the compaction funnel 14 is formed. You can also use the holding arm 15 and the bearing bush 16 and thereby increases - if it is stiff itself - the stiffness of the fuse compressor 13th

Mittels dieser Trennwand 24 wird verhindert, daß Fasern über die Oberkante des die beiden Verdichtungstrichter 14 und 14' enthaltenden, einstückigen Verdichtungskörpers und damit an den Verdichtungstrichtern vorbeilaufen. Diese dünne Trennwand 24 hat nur die Aufgabe, ein Umgehen der Verdichtungstrichter 14, 14' zu verhindern, das Haltern der Verdichtungstrichter wird auch bei dieser Ausführungsform allein durch den seitlich des Oberriemchens 12 und seitlich der Oberwalze 5 liegenden Haltearm 15 erreicht.By means of this partition 24 it is prevented that fibers over the Upper edge of the two compression hoppers 14 and 14 'containing one-piece compression body and thus on the compression funnel pass. This thin partition 24 has only the task of bypassing the compression funnels 14, 14 ' prevent the compression hopper from being held too this embodiment solely by the side of the top strap 12 and laterally the upper roller 5 lying arm 15 reached.

Es versteht sich, daß die Trennwand 24 ohne weiteres auch bei den einen einstückigen Verdichtungstrichter 14 aufweisenden Ausführungsformen der Erfindung gemäß den Figuren 3 und 5 einsetzbar ist. It is understood that the partition 24 is also readily available the embodiments having an integral compression funnel 14 the invention according to Figures 3 and 5 can be used is.
