Description

Die Erfindung betrifft das Führen von Fibrillenbündel durch einen Teil einer Spinnstrecktexturier- oder Strecktexturiermaschine und den Teil der Spinnstrecktexturier- und Strecktexturiermaschine, gemäss Oberbegriff der unabhängigen Patentansprüche.The invention relates to the guiding of fibril bundles through a part of a spin draw texturing or draw texturing machine and to the part of the spin draw texturing and draw texturing machine, according to the preamble of the independent patent claims.

Mit einem an sich aus der europäischen Patentanmeldung EP 0 784 109 A1 bekannten Texturierverfahren, in welchem mehrere einzelne Fibrillenbündel gleichzeitig auf einem Streckrollenpaar verstreckt und anschliessend in einer Texturiereinheit mit mehreren nebeneinander angeordneten Texturierdüsen texturiert werden, ergibt es sich einerseits, dass die einzelnen Fibrillenbündel auf dem Streckrollenpaar mit einem kleineren Abstand von Fibrillenbündel zu Fibrillenbündel geführt werden, als der von Texturierdüse zu Texturierdüse notwendige Abstand.With one in itself from the European patent application EP 0 784 109 A1 known texturing in which a plurality of individual fibril bundles stretched simultaneously on a pair of stretch rollers and then textured in a texturing unit with a plurality of juxtaposed texturing, it results on the one hand, that the individual fibril are performed on the pair of draw rolls with a smaller distance from fibril bundle to fibril bundle than the distance necessary from texturing nozzle to texturing nozzle.

Da andererseits die Bauhöhe der Maschine möglichst niedrig sein soll, um ein Einziehen der mit hoher Geschwindigkeit mit einer sogenannten Saugpistole eingesaugten Filamentbündel möglichst rasch vom Anfang bis zum Ende der Maschine zu ermöglichen, sollen die Abstände zwischen den einzelnen Verfahrenseinheiten möglichst klein sein.On the other hand, since the height of the machine should be as low as possible to allow retraction of the suctioned at high speed with a so-called suction gun filament bundles as quickly as possible from the beginning to the end of the machine, the distances between the individual process units should be as small as possible.

Diese Bedingungen sind besonders für die Führung der Fibrillenbündel zwischen der abgebenden Streckrolle und der Texturiereinheit unvorteilhaft, da einerseits der Abstand, wie erwähnt, auf den Streckrollen von Fibrillenbündel zu Fibrillenbündel möglichst klein sein soll während der Abstand von Texturierdüse zu Texturierdüse aus verschiedenen Gründen wesentlich grösser ist und deshalb die Fibrillenbündel von der Streckrolle zur Texturiereinheit stark gefächert und dadurch am Einlauf jeder einzelnen Texturierdüse umgelenkt werden müssen.These conditions are disadvantageous especially for the guidance of the fibril bundles between the donating stretch roll and the texturing unit, since on the one hand the distance, As mentioned, should be as small as possible on the stretch rollers of fibril to fibril bundle while the distance from texturing to texturing for different reasons and therefore the fibril bundles strongly stretched from the stretch roll to Texturi unit and thus must be redirected at the inlet of each texturing.

Dabei unterscheidet man auf der Streckrolle den kleineren Abstand von Fibrillenbündel zu Fibrillenbündel innerhalb einer Gruppe und den etwas grösseren Abstand von Gruppe zu Gruppe.A distinction is made on the stretch roller the smaller distance from fibril bundle to fibril bundle within a group and the slightly larger distance from group to group.

Um nun den Gruppenabstand zwischen der zweitletzten Gruppe und letzten, äussersten Gruppe trotz der genannten Fächerung einzuhalten, müssen zwischen den einzelnen Streckrollen eines Streckrollenpaares Führungen vorgesehen werden, welche die letzte Fibrillenbündelgruppe auf den Streckrollen derart entfernt von der zweitletzten Gruppe führt, dass trotz der Abgabebreite der letzten Fibrillenbündel von der Rolle an die Texturiereinheit der Gruppenabstand in einem akzeptablen Mass ist, um zu vermeiden, dass entweder zu lange Rollen notwendig werden oder die Gefahr besteht, dass die gefächerten Fibrillenbündel der letzten Gruppe benachbarte sich noch auf den Rollen befindliche Fibrillenbündel der vorangehenden Gruppe überdecken.In order to keep the group distance between the second last group and last, outermost group despite the aforementioned fan, guides must be provided between the individual stretch rollers of a pair of stretch rollers, which leads the last Fibrillenbündelgruppe on the stretch rollers so far from the second last group that despite the discharge width of last fibril bundle from the roll to the texturing unit is the group spacing to an acceptable degree to avoid either requiring too long rolls or the risk that the fanned fan fibrils of the last group would be adjacent fibril bunches of the preceding group still on the rolls cover.

Vorgenannte Führungen, seien es Umlenkungen zwischen den Rollen oder Umlenkungen vor dem Eingang jeder einzelnen Texturierdüse, haben den Nachteil, dass sie unwillkürlich ein unkontrolliertes Mass an Schädigungen, z.B. Deformation des Fibrillenquerschnittes, am einzelnen Fibrillenbündel erzeugen, und zwar insofern unkontrolliert, als die Umlenkung, insbesondere vor dem Eingang der einzelnen Texturierdüse, von Texturierdüse zu Texturierdüse unterschiedlich ist, so dass Texturierunterschiede letztlich im einzelnen Fibrillenbündel vorhanden sind, welche unter Umständen im Fertigprodukt, beispielsweise im Teppich, sichtbar werden.The above-mentioned guides, whether deflections between the rollers or deflections in front of the entrance of each individual texturing nozzle, have the disadvantage that they involuntarily cause an uncontrolled degree of damage, eg deformation of the fibril cross-section. produce on the individual fibril bundle, in so far as uncontrolled, as the deflection, especially before the entrance of each texturing, different from texturing to texturing, so that texturing differences are ultimately present in the individual fibril, which may be visible in the finished product, for example in the carpet become.

Es war deshalb Aufgabe der Erfindung, diese Nachteile zu beheben.It was therefore an object of the invention to remedy these disadvantages.

Die Aufgabe wird durch die Massnahmen im kennzeichnenden Teil der unabhängigen Ansprüche gelöst.The object is achieved by the measures in the characterizing part of the independent claims.

Weitere abhängige Ansprüche definieren vorteilhafte Ausführungsformen.Further dependent claims define advantageous embodiments.

Die Erfindung wird beispielsweise mittels der Figuren 1 bis 3 erklärt.The invention is for example by means of FIGS. 1 to 3 explained.

Es zeigt:

It shows:

Die Fig. 1 zeigt ein Streckrollenpaar 1, auch Duo genannt, mit den einzelnen Streckrollen 1A und 1B, auf welchen einzelne Fibrillenbündel 6 in Gruppen 6.1 aufgezogen sind, welche, in Kombination mit mindestens einem weiteren, vorangehenden Streckrollenpaar in an sich bekannter Weise gestreckt werden.The Fig. 1 shows a pair of stretching rollers 1, also called duo, with the individual stretch rollers 1A and 1B, on which individual fibril bundles 6 are mounted in groups 6.1, which, in combination with at least one other, preceding pair of stretching rollers are stretched in a conventional manner.

Dabei sind die Gruppen, wie in Fig. 2 gezeigt, mit einem Abstand A getrennt voneinander gehalten.The groups are as in Fig. 2 shown separated by a distance A.

Die Fibrillenbündel 6 der letzten Gruppe (Fig. 2) werden durch eine sich zwischen den Streckrollen 1A und 1B vorgesehene untere führende Umlenkung 2 sowie eine etwas weiter vorn, gegen das freie Ende der Rollen 1A und 1B sitzende, sich ebenfalls zwischen den Streckrollen 1A und 1B befindliche obere führende Umlenkung 3 umgelenkt und dabei geführt und zwar derart, dass die letzte Fibrillenbündelgruppe auf der Rolle 1A einen grösseren Abstand B zur vorhergehenden Gruppe auf den Streckrollen aufweisen, als der Abstand A. Dazu weisen die Umlenkungen 2 und 3 für jedes Fibrillenbündel eine Rille auf. Dadurch wird verhindert, dass Fibrillenbündel der letzten Gruppe aufgrund der Spreizung, infolge des wesentlichen grösseren Abstandes von Texturierdüsenmitte zu Texturierdüsenmitte als von Fibrillenbündel zu Fibrillenbündel innerhalb der Gruppe an einer Abgabestelle 15 berühren oder gar überdecken. Dabei können die Umlenkungen 2 und 3 entweder stationär oder von den Fibrillenbündel angetriebene Rollen sein.The fibril bundles 6 of the last group ( Fig. 2 ) are deflected by a provided between the stretch rollers 1A and 1B lower guide deflection 2 and a slightly farther forward, sitting against the free end of the rollers 1A and 1B, also located between the stretch rollers 1A and 1B located upper guide deflection 3 and guided it in such a way that the last fibril bundle group on the roll 1A has a greater distance B to the preceding group on the draw rolls than the distance A. For this purpose, the deflections 2 and 3 have a groove for each fibril bundle. This prevents fibril bundles of the last group from touching or even covering due to the spread, due to the substantially greater distance from texturing nozzle center to texturing nozzle center than from fibril bundle to fibril bundle within the group at a delivery point 15. The can Deflectors 2 and 3 may be either stationary or rollers driven by the fibril bundles.

Im weiteren handelt es sich bei der Abgabestelle um eine zur Rollenachse imaginäre parallele Gerade, entlang welcher die Fibrillenbündel nebeneinander laufen.Furthermore, the delivery point is an imaginary parallel straight line to the roller axis, along which the fibril bundles run side by side.

Die in die Texturiereinheit 4 einlaufenden Fibrillenbündel 6 werden am Eingang der Texturiereinheit 4, wie in Fig. 2 dargestellt, aufgrund der Spreizung der Fibrillenbündel zwischen der Abgabestelle 15 und dem Eingang in die Texturiereinheit 4 am Eingang umgelenkt.The fibril bundles 6 arriving in the texturing unit 4 are deposited at the entrance of the texturing unit 4, as in FIG Fig. 2 shown deflected due to the spread of the fibril bundles between the delivery point 15 and the entrance to the texturing unit 4 at the entrance.

Die Umlenkungen der Fibrillenbündel 6 an der unteren Umlenkung 2 und der oberen Umlenkung 3 sowie die Umlenkung am Eingang in die Texturiereinheit 4 verursachen, wie Eingangs erwähnt, aufgrund der Reibung an den Fibrillenbündeln eine von Fibrillenbündel zu Fibrillenbündel unterschiedliche und ausserdem nicht erwünschte Schädigung, welche eine Ungleichmässigkeit im fertigen Garn zur Folge hat.The deflections of the fibril bundles 6 at the lower deflection 2 and the upper deflection 3 and the deflection at the entrance to the texturing unit 4 cause, as mentioned at the beginning, due to the friction on the fibril bundles a different from fibril bundle to fibril bundle and also undesirable damage, which is a Unevenness in the finished yarn result.

Um diesem Nachteil abzuhelfen sind, wie in Fig. 4 dargestellt, die einzelnen Texturierdüsen 8 fächerförmig angeordnet und zwar derart, dass die mit strichpunktierten Linien dargestellten Längsachsen 16 jeder einzelnen Texturierdüse 8 coaxial mit einer, mit strichpunktierten Linien dargestellten Verbindungslinie 17, welche sich von der Abgabestelle 15 bis zum Ausgang jeder einzelnen Texturierdüse 8 erstreckt, verlaufen. Dabei entsprechen die Verbindungslinien 17 gleichzeitig dem Lauf der einzelnen Fibrillenbündel 6 von der Abgabestelle 15 bis in jede einzelne Texturierdüse 8 hinein.To remedy this disadvantage, as in Fig. 4 the individual texturing nozzles 8 are arranged fan-shaped in such a way that the longitudinal axes 16 of each individual texturing nozzle 8 shown in phantom line extend coaxially with a connecting line 17 shown by dotted lines, which extends from the discharge point 15 to the outlet of each individual texturing nozzle 8, run. there The connecting lines 17 simultaneously correspond to the course of the individual fibril bundles 6 from the discharge point 15 into each individual texturing nozzle 8.

Durch diese fächerförmige Anordnung der Texturierdüsen 8 kann, wie in Fig. 3 und 4 gezeigt, auf alle früher genannten Umlenkungsführungen verzichtet werden.By this fan-shaped arrangement of the texturing nozzles 8, as in 3 and 4 shown, to dispense with all previously mentioned deflection guides.

Die Texturierdüsen 8 geben je ein texturiertes Fibrillenbündel an eine Kühltrommel 5 ab und zwar je in eine einzelne, pro Fibrillenbündel, auf der Kühltrommel 5 vorgesehene Kühlbahn.The texturing nozzles 8 each deliver a textured fibril bundle to a cooling drum 5, and indeed each into a single, per fibril bundle, provided on the cooling drum 5 cooling path.

Die Kühltrommel 5 ist an sich ein, beispielsweise aus der EP 0 310 890 B1 bekanntes Element und hier weiter nicht beschrieben.The cooling drum 5 is a, for example from the EP 0 310 890 B1 known element and not further described here.

In Fig. 4 ist nur die eine Hälfte 4.1 der Texturiereinheit 4 von Fig. 3 dargestellt. Die andere Hälfte 4.2 ist, wie in Fig. 3 gezeigt, in Richtung III entfernt oder aufgeklappt worden. Dies hier lediglich, um den Verlauf der Fibrillenbündel 6 sowie der einzelnen Texturierdüsen 8 besser darstellen zu können.In Fig. 4 is only one half 4.1 of the texturing unit 4 of Fig. 3 shown. The other half is 4.2, as in Fig. 3 shown, removed in direction III or opened. This is merely to better illustrate the course of the fibril bundles 6 and of the individual texturing nozzles 8.

Aufklappbare Texturiereinheiten 4 an sich sind bereits in der europäischen Patentschrift EP-0 026 360 B1 sowie in EP-0 039 763 B1 gezeigt und beschrieben.Foldable Texturi units 4 are already in the European Patent EP-0 026 360 B1 as in EP-0 039 763 B1 shown and described.

Wie in Fig. 4 weiter dargestellt, werden die einzelnen Texturierdüsen 8 über einen Fördermediumverteilkanal 13 mit einem Fördermedium gespeist, so dass aufgrund eines an sich bekannten Venturieffektes die Fibrillenbündel 6 mittels des Fördermediums in die einzelnen Texturierdüsen 8 eingesaugt und durch den Förderteil 9 in den Texturierteil 10 gefördert werden, in welchem die Fibrillenbündel zu einem Pfropfen respektive texturierten Fibrillenbündel texturiert und von dort je in eine einzelne Kühlbahn 11 der Kühltrommel 8 gefördert werden.As in Fig. 4 further illustrated, the individual texturing 8 are fed via a Fördermediumverteilkanal 13 with a pumped medium, so that due to a per se known venturi effect the fibril bundles 6 are sucked by the conveying medium into the individual texturing 8 and conveyed by the conveying part 9 in the texturing 10, in which the fibril bundles textured to a graft or textured fibril bundles and from there each into a single cooling path 11 of the cooling drum 8 promoted.

Das Fördermedium wird durch einen Fördermediumzufuhrkanal 14 und via interne, hier nicht dargestellte Kanäle in die Fördermediumverteilkanäle 13 eingeführt.The conveying medium is introduced through a conveying medium supply channel 14 and via internal, not shown here channels in the Fördermediumverteilkanäle 13.

Die Erfindung ist nicht auf die dargestellte Anordnung des Fibrillenbündelverlaufes auf der Rolle 1A in Fig. 4 eingeschränkt. Grundsätzlich handelt es sich erfindungsgemäss um eine Fibrillenbündelführung, welche im wesentlichen keine stärkere Umlenkungen verursacht als beispielsweise diejenige, welche sich in Fig. 4 an der obersten Umfangslinie der Rolle 1A bis zur Abgabestelle 15 ergibt, welche einerseits von der Friktion zwischen Fibrillenbündel und Oberfläche der Rolle 1A und andererseits von der Fadenspannung im einzelnen Fibrillenbündel 6, erzeugt durch die Ansaugkraft der einzelnen Texturierdüse, und im weiteren von der Oberflächenbeschaffenheit der Rolle 1A abhängt.The invention is not limited to the illustrated arrangement of the fibril bundle course on the roll 1A in FIG Fig. 4 limited. Basically, according to the invention, it is a fibril bundle guide which essentially does not cause any stronger deflections than, for example, those which occur in Fig. 4 at the uppermost circumference of the roller 1A to the delivery point 15, which on the one hand by the friction between fibril and the surface of the roll 1A and on the other hand by the thread tension in the individual fibril bundle 6, generated by the suction force of the individual texturing, and in the other of the surface texture of the Role 1A depends.

Im Rahmen dieser Variationen kann die fächerartige Anordnung der einzelnen Texturierdüsen 8 variiert werden.Within the scope of these variations, the fan-like arrangement of the individual texturing nozzles 8 can be varied.
