Description

Die Erfindung betrifft einen Faserband-Kondensor an einer Textilmaschine, insbesondere an einem Streckwerk eines Flyers, gemäss dem Oberbegriff des Anspruches 1. Eine solche Vorrichtung ist durch die FR-A-2597119 bekanntgeworden.The invention relates to a sliver condenser on a textile machine, in particular on a drafting device of a flyer, according to the preamble of claim 1. Such a device has become known from FR-A-2597119.

Den Streckwerken von Flyern werden Faserbündel bzw. Faserbänder in paralleler Orientierung zugeleitet, in welchen sie verstreckt werden. Diese Streckwerke, die mindestens eine Vorverzugszone und eine Hauptverzugszone und deshalb drei Walzenpaare aufweisen, erzeugen an dem Austritts- bzw. Auslaufwalzenpaar ein Faserband, dessen Breite grösser ist als dessen Höhe. Die Drehungen im Faserband kommen durch die Flügelumdrehungen zustande und pflanzen sich bis zum Auslaufwalzenpaar zurück, wo sich das sog. Spinndreieck bildet. Die Kehlweite von herkömmlichen Kondensoren, die im Raum zwischen dem Austrittswalzenpaar und den Riemchen der Hauptverzugszone angeordnet sind, wird durch Optimierung bestimmt, derart, dass die seitliche Einengung des Faserbandes so klein wie möglich wird, ohne Stauungen in den Randbereichen des Faserbandes zu erzeugen. Denn die Breite des aus dem Austrittswalzenpaar heraustretenden Faserbandes bestimmt die Breite und indirekt die Länge des Spinndreieckes, das bezüglich Faserband- bzw. Luntenbruches ein neuralgischer Bereich ist. Der Wichtigkeit einer schmalen Faserbandbreite wegen kommen bei manchen Streckwerken Kondensierzonen zur Anwendung. Dazu wird ein zusätzliches Walzenpaar, das jetzt zum Austrittswalzenpaar wird, benötigt.The flyer drafting systems are fed with fiber bundles or fiber tapes in a parallel orientation, in which they are stretched. These drafting units, which have at least one pre-drafting zone and one main drafting zone and therefore three pairs of rollers, produce a fiber sliver on the pair of exit or discharge rollers, the width of which is greater than the height. The twists in the sliver result from the wing revolutions and plant themselves back to the pair of outlet rollers, where the so-called spinning triangle forms. The throat width of conventional condensers, which are arranged in the space between the exit roller pair and the aprons of the main draft zone, is determined by optimization in such a way that the lateral narrowing of the sliver becomes as small as possible without creating congestion in the edge areas of the sliver. This is because the width of the sliver emerging from the pair of exit rollers determines the width and indirectly the length of the spinning triangle, which is a sensitive area with regard to sliver or sliver breakage. Due to the importance of a narrow fiber bandwidth, condensing zones are used in some drafting systems. This requires an additional pair of rollers, which now becomes the pair of exit rollers.

Es ist Aufgabe der vorliegenden Erfindung, einen Faserbandkondensor vorzuschlagen, der bei gleichbleibender Kehlweite ein schmaleres Faserband erzeugen kann. Diese Aufgabe wird dadurch gelöst, dass ein schräg zur Laufrichtung des Faserbandes verlaufender, den ersten Kanal nachgeordneter Kanal vorgesehen ist, der eine quer zur Abzugsrichtung des Faserbandes vom Kondensor zu messende Lichtweite aufweist, wobei die Lichtweite kleiner ist als die Kehlweite. Dadurch ist es nunmehr möglich, das Spinndreieck erheblich zu reduzieren bzw. gänzlich zu eliminieren, sodass sich weniger Luntenbrüche ereignen. Pilotversuche haben dies bestätigt, bei welchen ebenfalls der Einfluss des Winkels der Seitenwandungen bezüglich des Faserbandes untersucht wird. Weitere vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der abhängigen Ansprüche 2-9. Die Erfindung wird nachfolgend anhand der Zeichnung näher erläutert. Es zeigen schematisch:

It is an object of the present invention to propose a sliver condenser which can produce a narrower sliver with the same fillet width. This object is achieved in that a channel which runs obliquely to the running direction of the sliver and is arranged downstream of the first channel is provided, which is a condenser which is to be measured transversely to the pulling direction of the sliver Has light width, the light width is smaller than the throat width. As a result, it is now possible to reduce the spinning triangle considerably or to eliminate it entirely, so that fewer rupture breaks occur. Pilot tests have confirmed this, in which the influence of the angle of the side walls with respect to the sliver is also examined. Further advantageous embodiments of the invention are the subject of dependent claims 2-9. The invention is explained below with reference to the drawing. They show schematically:

Fig. 1 zeigt ein Vierwalzen-Streckwerk 4 mit einem Faserband 5, das nacheinander Walzenpaar 6-7, 8-9, welches mit Riemchen 10,11 ausgestattet ist, 12-13 und das Austrittswalzenpaar 14-15 durchläuft und das als Lunte bzw. Vorgarn 16 in einen Flyerflügel 17 eingeführt ist. Der Bereich des Spinndreieckes wird mit dem Bezugszeichen 18 bezeichnet. Durch die Walzenpaare werden eine Vorverzugszone 19, eine Hauptverzugszone 20 und eine Kondensierzone 21 gebildet. Wie üblich, sind die Oberwalzen 6, 8, 12, 14 jeweils als Doppelwalzen ausgebildet und mit einem gemeinsamen, nicht dargestellten, hochklappbaren Streckwerksarm verbunden. Die Unterwalzen 7, 9, 13, 15 sind über die ganze Maschinenlänge miteinander verbunden. Die Laufrichtung des Faserbandes 5 bzw. der Lunte 16 ist mit dem Pfeil 22 angedeutet. Der erfindungsgemässe Kondensor 23 ist vorzugsweise in der Kondensierzone 21 nahe dem Austrittswalzenpaar 14,15 angeordnet.Fig. 1 shows a four-roll drafting device 4 with a sliver 5, which passes through the pair of rollers 6-7, 8-9, which is equipped with straps 10,11, 12-13 and the exit roller pair 14-15 and that as a fuse or Roving 16 is inserted into a flyer wing 17. The area of the spinning triangle is designated by the reference symbol 18. A pre-draft zone 19, a main draft zone 20 and a condensing zone 21 are formed by the pairs of rollers. As usual, the upper rollers 6, 8, 12, 14 are each designed as double rollers and connected to a common, not shown, foldable drafting arm. The lower rollers 7, 9, 13, 15 are connected to one another over the entire length of the machine. The running direction of the sliver 5 or the sliver 16 is indicated by the arrow 22. The The condenser 23 according to the invention is preferably arranged in the condensing zone 21 near the pair of outlet rollers 14, 15.

Fig. 2 zeigt einen Faserbandkondensor 30, der meistens im Raum 24 zwischen dem Walzenpaar 12,13 und den Riemchen 10,11 angeordnet ist. Zwei Seitenwandungen 31,32 konvergieren in Richtung des Pfeiles 22. Der kleinste Abstand zwischen den Wandungen 31,32 ist die Kehlweite 33, welche in diesem Fall ebenfalls die Lichtweite 34 ist. Unter Lichtweite wird die grösste seitliche Ausdehnung einer Lichtprojektion in Richtung des Pfeiles 22 verstanden.2 shows a sliver condenser 30, which is usually arranged in the space 24 between the pair of rollers 12, 13 and the straps 10, 11. Two side walls 31, 32 converge in the direction of arrow 22. The smallest distance between the walls 31, 32 is the fillet 33, which in this case is also the light width 34. The light width is understood to mean the greatest lateral extension of a light projection in the direction of arrow 22.

Der erfindungsgemässe, in Fig. 3 gezeigte Kondensor 23 hat ebenfalls Seitenwandungen 40,41, welche in Laufrichtung des Faserbandes 5 ebenfalls konvergieren und eine Kehlweite 42 bilden, welche zum Vergleich mit dem Kondensor 30 im gleichen Massstab gezeichnet ist. Die Kehlweite 33 sowie die Kehlweite 42 werden also rechtwinklig zur Laufrichtung des Faserbandes 5 gemessen. In Laufrichtung des Faserbandes 5 der Kehlweite 42 nachgeordnet ist ein Kanal 43 schräg zur Laufrichtung des Faserbandes 5 angeordnet. Die Wandung 40 ist geradlinig - eine gewölbte bzw. konkave Wandung wäre auch möglich - durchgezogen, so dass sie auch eine Seitenwandung des Kanals 43 bildet. Die Kehlweite 42 bleibt in ihrer Grösse beibehalten (gleich gross gezeichnet wie die Kehlweite 33), da die andere Seitenwandung 44 des Kanales 43 parallel zur Wandung 40 verläuft. Die Lichtweite 45, die ebenfalls rechtwinklig zur Laufrichtung des Faserbandes 5 gemessen wird, ist in diesem Fall nicht gleich der Kehlweite 42, sondern kleiner. Der Durchmesser der Lunte 16 entspricht etwa der Lichtweite 45 bei den gezeichneten Abmessungen. Mit Winkeln 48,49 der Seitenwandungen 40,41 zur Laufrichtung des Faserbandes 5 von beide etwa 45° sind bereits erfolgversprechende Resultate erzielt worden. Möglich wäre auch ein Winkel 48 von etwa 45° und ein Winkel 49 von etwa 60°. Es ist auch möglich, die in der Figur linke Begrenzung 50 der Kehlweite 42 weiter nach rechts zu verlegen; dadurch wird die Lichtweite 45 kleiner, bis sie auf Null kommt. Wird die Begrenzung 50 noch mehr nach rechts verlegt, wird die Lichtweite 45 sogar negativ; dies ist in Fig. 4 gezeigt. Diese Ausgestaltung kann besonders vorteilhaft sein.The condenser 23 according to the invention, shown in FIG. 3, likewise has side walls 40, 41, which likewise converge in the running direction of the sliver 5 and form a fillet 42, which is drawn on the same scale for comparison with the condenser 30. The fillet 33 and the fillet 42 are therefore measured at right angles to the running direction of the sliver 5. A channel 43 is arranged at an angle to the direction of travel of the sliver 5 in the running direction of the sliver 5. The wall 40 is rectilinear - a curved or concave wall would also be possible - so that it also forms a side wall of the channel 43. The fillet 42 remains the same size (drawn the same size as the fillet 33), since the other side wall 44 of the channel 43 runs parallel to the wall 40. The light width 45, which is also measured at right angles to the running direction of the sliver 5, is not equal to the throat width 42 in this case, but smaller. The diameter of the fuse 16 corresponds approximately to the light width 45 in the dimensions shown. With angles 48, 49 of the side walls 40, 41 to the running direction of the sliver 5 of both approximately 45 °, promising results have already been achieved. An angle 48 of approximately 45 ° and an angle 49 of approximately 60 ° would also be possible. It is also possible to move the left limit 50 of the throat 42 in the figure further to the right; this reduces the light range 45 until it comes to zero. If the boundary 50 is moved even more to the right, the light range 45 even becomes negative; this is shown in FIG. 4. This configuration can be particularly advantageous.

In Fig. 4 ist ein Faserbandkondensor in doppelter Ausführung in Stellung in der Kondensierzone 21 gezeigt, wobei die Kondensoren 23 und 23.1 bezüglich des Schrägverlaufes des Kanales 43 spiegelbildlich gestaltet sind und mittels eines einstückigen Haltebügels 53 miteinander verbunden sind. Aus der Fig. 1, wo der Haltebügel 53 der Übersichtlichkeit wegen weggelasssen wurde, und Fig. 5 ist ersichtlich, dass die dem Walzenpaar 14,15 zugewandten Bereiche 54,55 den Radien der Walzen 14,15 angepasst sind, damit der Faserbandkondensor so nahe wie möglich am Walzenpaar 14,15 plaziert werden kann. Zwischen den konkaven Bereichen 54,55 ist eine rechtwinklig zur Faserebene angeordnete Fläche 56 vorhanden, die mindestens so hoch ist wie die Dicke des Faserbandes 5. Bei der spiegelbildlichen Anordnung der beiden Faserbandkondensoren 23, 23.1 ist es unerheblich, ob die Kanäle 43 in Laufrichtung des Faserbandes 5 gesehen zueinander konvergieren oder divergieren. Zweck dieser spiegelbildlichen Anordnung ist es, die vom Faserband herrührenden seitlichen Kräfte auf die Faserbandkondensoren 23,23.1 auszugleichen. In Fig. 4 sind zur Hervorhebung des Doppelkondensors 23,53,23.1 die darunter liegenden unteren Walzen 13,15 und die dazugehörenden Zylinder 57,58 gestrichelt gezeichnet. Der Haltebügel 53 hat zwei Bogenstücke 59,60, welche auf die Zylinder 57,58 gleitend aufliegen, sodass der Doppelkondensor 23,53,23.1 höhenmässig gesichert ist und die beiden Faserbänder 5 den Doppelkondensor gemäss der Changierbewegung seitlich bewegen können. Um den Doppelkondensor so leicht wie möglich zu machen, sollte der Haltebügel aus dünnem Stahldraht und die Kondensoren 23,23.1 aus Kunststoff sein. Wegen der Herstellung und Montage ist ein einstückiger Haltebügel 53 vorteilhaft. Eine Abschrägung 61 kann vorteilhaft sein. Die gewählte Kehlweite 42 und die Höhe der Fläche 56 richten sich nach dem Umfang des Faserbandes 5.4 shows a sliver condenser in duplicate in position in the condensing zone 21, the condensers 23 and 23.1 being designed in mirror image with respect to the oblique course of the channel 43 and being connected to one another by means of a one-piece holding bracket 53. From FIG. 1, where the holding bracket 53 has been left out for the sake of clarity, and FIG. 5 it can be seen that the regions 54, 55 facing the pair of rollers 14, 15 are adapted to the radii of the rollers 14, 15, so that the sliver condenser is so close can be placed on the pair of rollers 14, 15 as possible. Between the concave regions 54, 55 there is a surface 56 arranged at right angles to the fiber plane, which is at least as high as the thickness of the fiber band 5. In the mirror-image arrangement of the two fiber band condensers 23, 23.1, it is irrelevant whether the channels 43 run in the direction of the Sliver 5 seen to converge or diverge. The purpose of this mirror-image arrangement is to compensate for the lateral forces from the sliver on the sliver condensers 23, 23.1. In FIG. 4, to emphasize the double condenser 23, 53, 23.1, the lower rollers 13, 15 below and the associated cylinders 57, 58 are drawn in dashed lines. The holding bracket 53 has two curved pieces 59, 60 which slide on the cylinders 57, 58, so that the height of the double condenser 23, 53, 23.1 is secured and the two slivers 5 can move the double condenser laterally according to the traversing movement. To make the double condenser as light as possible, the bracket should be made of thin steel wire and the condensers 23, 23.1 should be made of plastic. Because of the manufacture and assembly, a one-piece bracket 53 is advantageous. A bevel 61 can be advantageous. The chosen one The fillet width 42 and the height of the surface 56 depend on the circumference of the sliver 5.
