Description

Die Erfindung betrifft eine Spinnmaschine nach dem Oberbegriff der unabhängigen Ansprüche 1 und 2. Weiter wird sie auch zur Anwendung bei Verdichtungsspinnmaschinen nach Anspruch 4 vorgeschlagen. Derartige Spinnmaschinen haben entweder ein Streckwerk mit einer speziellen Auslaufwalze, welche an eine Saugeinrichtung angeschlossen ist, oder es ist eine mit Unterdruck arbeitende Verdichtungseinrichtung an ein konventionelles zweistufiges Streckwerk mit drei Zylinderpaaren angeschlossen. Die Verdichtung geschieht auf einem mit dem Faserverband fortbewegten luftdurchlässigen Verdichtungselement, das von innen her mit Unterdruck beaufschlagt ist, wobei die Verdichtung durch die quer gegen den Faserverband anströmende Saugluft bewirkt wird.The invention relates to a spinning machine according to the preamble of the independent claims 1 and 2. Further, it is also proposed for use in compaction spinning machines according to claim 4. Such spinning machines either have a drafting system with a special outlet roller which is connected to a suction device, or it is connected to a conventional two-stage drafting system with three pairs of cylinders operating under vacuum compression device. The compression takes place on a moving with the fiber structure air-permeable compression element, which is acted upon from the inside with negative pressure, wherein the compression is effected by the inflowing transversely against the fiber structure suction air.

Die US-A-5,577,298 beschreibt ein Doppelriemchenstreckwerk, welches zwischen der Austrittsöffnung der Riemchenführung und dem Klemmspalt des Lieferzylinderpaares einen mechanischen Verdichter enthält, welcher das Faserband mechanisch verdichtet.The US-A-5,577,298 describes a Doppelriemchenstreckwerk, which contains a mechanical compressor between the outlet opening of the Riemchenführung and the nip of the delivery cylinder pair, which mechanically compresses the sliver.

Mit der Erschliessung neuer Einsatzgebiete insbesondere von Verdichtungsspinnmaschinen entsteht das Bedürfnis, den Faserverband vor der Verdichtung auf seinem Weg durch das Streckwerk und gegebenenfalls zur Verdichtungseinrichtung möglichst vollkommen zu kontrollieren.With the development of new fields of application, especially of compaction spinning machines, the need arises to control the fiber structure as completely as possible before it is compacted on its way through the drafting system and optionally to the compacting device.

In einer Ausführungsform wird dies durch ein Umlenkelement erreicht, dessen Oberfläche wenigstens von einem Teil der Fasern bestrichen wird, bevorzugt so, dass sämtliche Fasern eines Faserverbandes in derselben Weise und/oder derselben Richtung umgelenkt werden. Dies wird bevorzugt durch ein prismatisches Umlenkelement - stabförmig mit im wesentlichen einheitlichen Querschnitten erreicht, welches quer zur Flussrichtung des Faserstromes angeordnet ist und in Längsrichtung der Streckwerkszylinder angeordnet ist. Dieses Führungselement kann unmittelbar vor dem Auflaufen des Faserverbandes auf ein Verdichtungselement angeordnet sein. Die Richtungsänderung des Faserverbandes durch das Führungselement beträgt dabei bevorzugt 1.5 bis 5°.According to the invention, a special guide is provided for this purpose in the main draft of the drafting system and / or before reaching the compacting device, which allows drifting apart of the drawn fibers less than in conventional drafting systems, without imposing significant changes in direction on the individual fibers. In one embodiment, this is achieved by a deflection element, the surface of which is at least coated by a part of the fibers, preferably so that all the fibers of a fiber structure are deflected in the same way and / or the same direction. This is preferred by a prismatic deflection - rod-shaped achieved with substantially uniform cross-sections, which is arranged transversely to the flow direction of the fiber stream and is arranged in the longitudinal direction of the drafting cylinder. This guide element can be arranged immediately before the emergence of the fiber structure on a compression element. The direction change of the fiber structure by the guide element is preferably 1.5 to 5 °.

The Oberriemchen 5 is driven in contact with the Unterriemchen 3 by this, wherein the vorverzugsfeld between inlet cylinder 42 and center cylinder 3 zoom out fibers of the fiber structure 11 are retained in the main drafting zone against the train of the discharge cylinder 2. The outlet cylinder 2 is designed in this embodiment as a compression element 19, that is, as an internally evacuated, perforated drum. The Oberriemchen 5 wraps around the one hand, the second upper roller 3 ', on the other hand, a spacer 32 which sits on the cage 30. Between the discharge point of the fiber structure 11 from Unterriemchen 4 and Oberriemchen 3 and the outlet cylinder 2 with the third upper roller 2 ', a guide member 34 is arranged, which, as shown in FIG FIG. 1 the fiber structure 11 deflects a little, whereby a tight guidance of the fibers of the fiber structure 11 is achieved and in particular shorter fibers are prevented from dissolving from the dressing. Preferably, a round rod is used in particular with a diameter between 3 and 6 mm as a guide element 34. The guide element 34 is arranged as close as possible to the surface of the outlet cylinder 2 or the compression element 19, with a distance of less than 1 mm. The fiber structure runs after a deflection by the guide member 34 by a few degrees on the surface of the compression element 19, wherein the looping path between the nip of the third top roller 2 'and the fourth top roller 1' is located on the compression element 19. A screen 19 'above the compression element 19 ensures a guidance of the incoming suction air as parallel as possible to the axis of the outlet cylinder 2. The fiber structure is then preferably screwed by means of a ring spinning device 40 and wound onto a yarn package.

Figur 2 und Figur 2a zeigen vergrössert Teile der Einrichtung in der Umgebung der Führung 34, mit der eine Umlenkung des Faserverbandes 11 um den Winkel α = 1.5...6° bewirkt wird. Mit vorzugsweise einer einzigen Einstellung des Führungselements der Führung 34 können Garne im Feinheitsbereich Ne 3 bis 100, vorzugsweise 3...50, insbesondere 3 bis 30 versponnen werden. Die Vorlage kann aus allen bekannten spinnbaren Fasermaterialien auch mit hohem Kurzfaseranteil bestehen, besonders kardierte Baumwolle, auch MMF, PES, Blends. Dank der Führung 34 werden gute Garnqualitätswerte erreicht. Die Bezugszeichen in den Figuren 2 und 2a gelten analog zu jenen in Figur 1. Figure 2 and Figure 2a show enlarged parts of the device in the vicinity of the guide 34, with a deflection of the fiber structure 11 by the angle α = 1.5 ... 6 ° is effected. With preferably a single adjustment of the guide element of the guide 34, yarns in the fineness range Ne 3 to 100, preferably 3 to 50, in particular 3 to 30, can be spun. The template may consist of all known spinnable fiber materials also with high short fiber content, especially carded cotton, also MMF, PES, blends. Thanks to the guide 34 become good yarn quality values reached. The reference numerals in the Figures 2 and 2a apply analogously to those in FIG. 1 ,

Figur 3 zeigt zwei Ausführungsformen für die Befestigung der Führung 34 im Streckwerk. Der Käfig 30 zur Führung der Oberriemchen 5 ist mit zweiten Oberwalzen 3' an der erwähnten Belastungseinrichtung 10 ortsfest, aber schwenkbar montiert. Beim ersten Ausführungsbeispiel des Führungselements der Führung 34 erstreckt sich dieses über die gesamte Länge eines Abschnitts des Käfigs 30 in Figur 3. Die Enden des Führungselements 34 sind durch Halteelemente 340, 340' gefasst. Die Halteelemente 340 sind ortsfest an den Enden des Käfigs 30 angebracht, beispielsweise mit Hilfe von Befestigungselementen 342 in Form von Stiften oder Schrauben. Die Halteelemente 340 können beispielsweise als Blattfedern aus Federstahl gefertigt sein. Sie können mittels Befestigungsstiften 342 in Bohrungen in Flucht der Befestigungselemente 342 seitlich in die Enden der Käfige eingeschnappt werden. FIG. 3 shows two embodiments for the attachment of the guide 34 in the drafting system. The cage 30 for guiding the Oberriemchen 5 is stationary with second upper rollers 3 'to the mentioned load device 10, but pivotally mounted. In the first embodiment of the guide element of the guide 34, this extends over the entire length of a portion of the cage 30 in FIG. 3 , The ends of the guide element 34 are held by holding elements 340, 340 '. The holding elements 340 are fixedly attached to the ends of the cage 30, for example by means of fastening elements 342 in the form of pins or screws. The holding elements 340 may be made, for example, as leaf springs made of spring steel. They can be snapped laterally into the ends of the cages by means of fastening pins 342 in bores in alignment with the fastening elements 342.

Gemäss einem zweiten Ausführungsbeispiel der Führung 34 im rechten Teil von Figur 3 wird ein vergleichsweise kurzes Führungselement 34 mittels zweier Halteelemente 340, 340', an deren Enden Reiter 342 sitzen, bei einem Distanzstück 32 auf die rechte Längskante des Käfigs 30 aufgesteckt. Die Reiter 342 sitzen dabei direkt neben Reitern 320 des Distanzstücks 32. Das Distanzstück dient zur Führung des Oberriemchens 5, wobei dieses durch das Umlenkelement 33 zwischen den Reitern 320 umgelenkt wird. Die Reiter 342 können wie die Reiter 320 des Distanzstücks, in perspektivischer Darstellung gezeigt, ausgeführt sein, mit einer grösseren Distanz zwischen den Reitern 342 als zwischen den Reitern 320. Ein Halteelement 340 sitzt in der in Figur 3 gezeigten Weise mit dem Reiter 342 neben dem Distanzstück 32 auf dem Käfig 30. Neben dem Käfig 30 sind das Distanzstück 32 in perspektivischer Darstellung und das kurze Führungselement 34 mit den Halteelementen 340 in perspektivisch/schematischer Darstellung gezeigt. Das Führungselement der Führung 34 ist, wie bereits erwähnt, ein bevorzugt kreiszylindrisch prismatisches Element. Die Führung 34kann auch direkt auf dem Umlenkelement 33 befestigt sein.According to a second embodiment of the guide 34 in the right part of FIG. 3 is a relatively short guide member 34 by means of two holding elements 340, 340 ', sit at the ends tabs 342, plugged at a spacer 32 on the right longitudinal edge of the cage 30. The riders 342 sit directly next to riders 320 of the spacer 32. The spacer serves to guide the Oberriemchens 5, which is deflected by the deflector 33 between the riders 320. The tabs 342 may be like the tabs 320 of the spacer, shown in perspective, executed, with a greater distance between the tabs 342 than between the tabs 320. A holding member 340 is seated in the in FIG. 3 shown in addition to the cage 30, the spacer 32 in a perspective view and the short guide element 34 with the holding elements 340 are shown in perspective / schematic illustration. The guide element of the guide 34 is, as already mentioned, a preferably circular-cylindrical prismatic element. The guide 34 can also be fastened directly on the deflection element 33.

Ein weiteres Ausführungsbeispiel eines Streckwerks mit einer Verdichtungseinrichtung ist in Figur 4 dargestellt. Vom Streckwerk 1 a sind lediglich der Mittelzylinder 3 und der Auslaufzylinder 2 mit mittels der Belastungseinrichtung 10 angepressten Oberwalzen 3' (zweite Oberwalze) und 2' (dritte Oberwalze) gezeigt. Zwischen der dritten Oberwalze 2' und der vierten Oberwalze 1' sitzt eine weitere Walze 27, die zum Antrieb der vierten Oberwalze 1' durch die dritte Oberwalze 2' dient. Im Gegensatz zur Anordnung in Figur 1 ist der Auslaufzylinder 2 nicht als Verdichtungselement ausgeführt; dieses befindet sich links daneben, wobei ein Unterdrucksystem 15 durch ein Verdichtungselement 19 in Form eines luftdurchlässigen Riemchens umschlungen wird. Das Verdichtungselement 19 wird durch die vierte Oberwalze 1' mit dem Faserverband 11 bzw. dem Garn 25 entlang der Verdichtungszone 13 vorwärts bewegt. Die Verdichtung des Faserverbandes 11 in der Verdichtungszone 13 geschieht entlang eines Saugschlitzes 17, durch den Luft in das Unterdrucksystem 15 eingesogen wird. Die Achsen 8 und 21 der dritten Oberwalze 2' bzw. der vierten Oberwalze 21 werden durch die Belastungseinrichtung 10 gehalten. Der Faserverband 11 wird durch ein Oberriemchen 5 an der zweiten Oberwalze 3' sowie ein Unterriemchen 4 am Mittelzylinder 3 im Hauptverzugsfeld des Streckwerks geführt, wobei zwischen den Riemchen 4 und 5 in bekannter Weise eine Führung 34 angeordnet ist, mit welcher der Faserverband um einen sehr kleinen Winkel zwischen 1.5 und 6° umgelenkt wird. Das Führungselement 34 kann, wie im Zusammenhang mit Figur 3 beschrieben, an einem Käfig 5' des Oberriemchens 5 befestigt sein. Vom Klemmspalt 23 zwischen Auslaufzylinder 2 und der dritten Oberwalze 2', welche gegen diesen gedrückt wird, bis zum Erreichen der Verdichtungszone 13 kann der Faserverband 11 durch ein weiteres Führungselement 34' unterstützt werden. Dieses Führungselement kann beispielsweise wie das beschriebene Führungselement 34 als kreiszylindrischer Stab oder, wie gestrichelt angedeutet, als flaches, mehr oder weniger ebenes Führungsteil ausgebildet sein, das sich mindestens im Bereich des Faserverbandes 11 entlang der Spinnmaschine erstreckt. Das erste Führungselement 34 verbessert, wie bereits weiter oben beschrieben, den Zusammenhalt der Fasern im Hauptverzugsfeld des Streckwerks zwischen Mittelzylinder 3 und Auslaufzylinder 2, während das zweite Führungselement 34' sozusagen als Führungstisch für den Faserverband zwischen Auslaufzylinder 2 und Verdichtungselement 19 dient. Der zweite Klemmspalt 24 zwischen der Verdichtungseinrichtung 1 und der vierten Oberwalze 1' begrenzt den Drall im Garn 25, der von einer nachgeördneten Spinneinrichtung herrührt. Die Führung 34 ist so anzuordnen, dass eine Verbindungslinie zwischen dem Klemmspalt 23 des Auslaufzylinderpaares 2, 2' und dem ablaufseitigen Klemmpunkt des Riemchenpaares 4, 5 das Führungselement 34 teilweise durchdringt.Another embodiment of a drafting system with a compression device is in FIG. 4 shown. From the drafting system 1 a only the central cylinder 3 and the outlet cylinder 2 are pressed by means of the loading device 10 top rollers 3 '(second top roller) and 2' (third top roller) shown. Between the third top roller 2 'and the fourth top roller 1' sits another roller 27, which serves to drive the fourth top roller 1 'through the third top roller 2'. Unlike the arrangement in FIG. 1 the discharge cylinder 2 is not designed as a compression element; this is on the left next to it, wherein a vacuum system 15 is wrapped by a compression element 19 in the form of an air-permeable belt. The compression element 19 is moved forward by the fourth top roller 1 'with the fiber structure 11 or the yarn 25 along the compression zone 13. The compression of the fiber structure 11 in the compression zone 13 takes place along a suction slot 17, is sucked through the air in the vacuum system 15. The axes 8 and 21 of the third top roller 2 'and the fourth top roller 21 are held by the loading device 10. The fiber structure 11 is guided by a Oberriemchen 5 on the second upper roller 3 'and a Unterriemchen 4 on the central cylinder 3 in the main drafting zone of the drafting system, between the straps 4 and 5 in a known manner a guide 34 is arranged, with which the fiber structure around a very small angle between 1.5 and 6 ° is deflected. The guide member 34 may, as in connection with FIG. 3 described, be attached to a cage 5 'of Oberriemchens 5. From the nip 23 between outlet cylinder 2 and the third top roller 2 ', which is pressed against this, until reaching the compression zone 13, the fiber structure 11 can be supported by a further guide element 34'. This guide element may be formed, for example, as the described guide element 34 as a circular cylindrical rod or, as indicated by dashed lines, as a flat, more or less flat guide member extending at least in the region of the fiber structure 11 along the spinning machine. The first guide element 34 improves, as already described above, the cohesion of the fibers in the main drafting zone of the drafting between central cylinder 3 and outlet cylinder 2, while the second guide element 34 'serves as a kind of guide table for the fiber structure between outlet cylinder 2 and compression element 19. The second nip 24 between the compacting device 1 and the fourth upper roller 1 ' limits the twist in the yarn 25, which results from a nachgeördneten spinning device. The guide 34 is to be arranged so that a connecting line between the nip 23 of the outlet cylinder pair 2, 2 'and the outlet-side clamping point of the pair of straps 4, 5, the guide member 34 partially penetrates.

Die Oberflächenbeschaffenheit der Umlenkung oder Führung ist je nach gewünschtem Effekt und Rohstoff zu wählen. Die Umlenkung kann fest oder rotierbar gelagert werden. Das Führungselement 34 kann auch an der Umlenkbrücke 40 befestigt sein.The surface condition of the deflection or guide should be selected according to the desired effect and raw material. The deflection can be stored fixed or rotatable. The guide element 34 may also be attached to the deflection bridge 40.

Die Führung 34 kann nach Fig. 5 zum Auslaufzylinder 2,2' hin konkav und zum Faserverband 11 hin konvex gekrümmt sein.The guide 34 can after Fig. 5 be concave towards the outlet cylinder 2,2 'and convexly curved towards the fiber structure 11.

Die Führung 34 kann gemäss Fig. 6 zwischen zwei Oberwalzen 2', 3' zum Riemchen 5 hin so angeordnet sein, dass dieses von aussen betrachtet durch die Führung 34 eine konkave Umlenkung erfährt. Damit ist es möglich, das Riemchen näher an die Oberwalze 2' heranzuführen, womit der Faserverband 11 wenn nicht zusätzlich, so doch auf einer längeren Strecke geführt wird.The guide 34 can according Fig. 6 between two top rollers 2 ', 3' to the strap 5 out so that this viewed from the outside through the guide 34 undergoes a concave deflection. This makes it possible to bring the strapping closer to the top roller 2 ', whereby the fiber structure 11 is guided, if not in addition, at least over a longer distance.

Gemäss Fig. 2 und 4 kann die zusätzliche Führung 34 für den Faserverband in Transportrichtung des Faserverbandes in einem oder nach einem Verstreckungsbereich 4,5 und vor einem Verdichtungsbereich, insbesondere vor dem Auflaufen des Faserverbandes 11 auf einem Verdichtungselement 19 der Verdichtungseinrichtung, angeordnet ist.According to Fig. 2 and 4 For example, the additional guide 34 for the fiber structure can be arranged in the transport direction of the fiber structure in or after a stretching region 4, 5 and before a compression region, in particular before the fiber structure 11 comes to rest on a compression element 19 of the compression device.

Nach Fig. 7 kann die Führung 34 mit Halteelementen 340a und 340c an Achsen von Oberwalzen 2',3' oder an einem Belastungsarm 344 befestigt sein.To Fig. 7 For example, the guide 34 may be fastened with support members 340a and 340c to axes of upper rollers 2 ', 3' or to a loading arm 344.
