Abstract

Eine Spinnanlage für Chemiefasern umfaßt einen perforierten Spinnschacht (3), durch den Luft von außen nach innen in ein frischgesponnenes Faserbündel geblasen wird. Im Inneren des Spinnschachtes sind mehrere Ringe mit axialem Abstand angeordnet. Diese Ringe lassen im Inneren des Spinnschachtes lediglich einen Querschnitt frei, der im wesentlichen dem Querschnitt des Faserbündels entspricht.A spinning plant for man-made fibers comprises a perforated spinning shaft (3) through which air is blown from the outside into a freshly spun fiber bundle. In the interior of the spinning shaft, several rings are arranged at an axial distance. These rings only leave a cross-section inside the spinning shaft which essentially corresponds to the cross-section of the fiber bundle.

Description

Die Erfindung betrifft eine Spinnanlage für Chemiefasern mit einem an die Spinndüse anschließenden, als Rohr ausgebildeten Spinnschacht, dessen Teillänge perforiert ist und einen Anblaskasten durchdringt.The invention relates to a spinning system for man-made fibers with a spinning shaft, which is formed as a tube and connects to the spinneret, the partial length of which is perforated and penetrates a blow box.

Die Erfindung geht von einem Stand der Technik aus, wie er beispielsweise in der DE-OS 34 06 347 beschrieben ist. Bei einer Spinnanlage für Chemiefasern mit einem an die Spinndüse anschließenden Anblaskasten und einem diesen durchdringenden Spinnschacht ist der Spinnschacht im sog. Verteilerteil des Anblaskastens,nicht jedoch in seinem Einlaßteil, perforiert. Einlaßteil und Verteilerkasten sind durch Leitelemente verbunden, deren Aufgabe die Vergleichmäßigung der Strömung des Anblasmediums ist.The invention is based on a prior art, as described for example in DE-OS 34 06 347. In a spinning system for man-made fibers with a blow box adjoining the spinneret and a spinning shaft penetrating it, the spinning shaft is perforated in the so-called distributor part of the blow box, but not in its inlet part. The inlet part and the distributor box are connected by guide elements, the task of which is to even out the flow of the blowing medium.

Diese Spinnanlage hat sich in der Praxis bewährt. In einigen Fällen war jedoch die durch den perforierten Teil des Spinnschachts auf die frisch ersponnene Fadenschar geleitete Anblasluft in ihrer Wirkung nicht so effektiv wie erwünscht. Die der vorliegenden Erfindung zugrunde liegende Aufgabe besteht danach darin, die Anblaswirkung bei hoher Gleichmäßigkeit wesentlich zu verbessern.This spinning system has proven itself in practice. In some cases, however, the blowing air directed through the perforated part of the spinning shaft onto the freshly spun thread group was not as effective as desired in its effect. The object on which the present invention is based is to significantly improve the blowing effect with high uniformity.

Diese Aufgabe wird erfindungsgemäß durch eine Spinnanlage der eingangs beschriebenen Art dadurch gelöst, daß die der Spinndüse benachbarte perforierte Teilänge des Spinnschachts mit Mitteln ausgestattet ist, durch die die Anblasluft eine im wesentlichen radial zur Spinnschachtachse gerichtete Geschwindigkeitskomponente erhält und wobei die Mittel den freien Querschnitt des Spinnschachtabschnitts am Ort ihrer jeweiligen Anordnung bis auf einen zentrischen Fadendurchlaß einengen. In einer Ausführungsform der Erfindung sind die genannten Mittel mit der Innenwand der perforierten Spinnschachtteillänge verbundene Ringe, deren freier Querschnitt einen Durchmesser aufweist, der im wesentlichen dem Durchmesser der örtlichen Einhüllenden der Fadenschar entspricht, jedoch nicht kleiner ist als dieser. Diese Ringe können eben und senkrecht zur Spinnschachtachse angeordnet sein oder auch eine in die allgemeine Fadenlaufrichtung weisende Trichterform haben. Die Lochkanten der Ringe sind vorteilhaft abgerundet, um eine Beschädigung von Fäden der Fadenschar auszuschließen. Die Ringlochbegrenzung kann auch als eine Art Ringwulst ausgebildet sein, der dann um eine Beeinflußung der Luftführung zu vermeiden, über die gegen den Fadenlauf weisende Ringfläche nicht hinausstehn, sondern in ihr beginnen soll und so mit ihr bündig liegt.This object is achieved according to the invention by a spinning system of the type described at the outset in that the perforated partial length of the spinning shaft adjacent to the spinneret is equipped with means by which the blowing air receives a speed component which is directed essentially radially to the spinning shaft axis and the means have the free cross section of the spinning shaft section at the location of their respective arrangement except for a central thread let it narrow. In one embodiment of the invention, the means mentioned are rings connected to the inner wall of the perforated spinning shaft part length, the free cross section of which has a diameter which essentially corresponds to the diameter of the local envelope of the thread sheet, but is not less than this. These rings can be arranged flat and perpendicular to the spinning shaft axis or can also have a funnel shape pointing in the general direction of the thread. The perforated edges of the rings are advantageously rounded to prevent damage to the threads of the thread sheet. The ring hole delimitation can also be designed as a type of ring bead, which then, in order to avoid influencing the air flow, should not protrude beyond the ring surface pointing against the thread path, but should begin in it and thus lie flush with it.

Eine Verbesserung der Anblasung kann schon durch die Anordnung nur eines Ringes erzielt werden, bevorzugt werden jedoch mehrere Ringe vorgesehen; mindestens sollten es aber zwei sein.An improvement in the blowing can already be achieved by arranging only one ring, but preferably several rings are provided; at least there should be two.

Der Durchmesser der Ringöffnungen ist vorteilhaft nur um ein geringes, eben das Anlaufen der außenliegenden Fäden der Fadenschar verhinderndes Maß größer als der Durchmesser der gedachten Einhüllenden der Fadenschar und zwar so, daß die Ringöffnung in ihren jeweiligen Abmessungen dem Abmaß der ggf. von der Spinndüse zu ihrer Zusammenfassung konisch zusammenlaufenden Fadenschar am Ort des jeweils betroffenen Ringes angepaßt ist.The diameter of the ring openings is advantageously only by a small amount, which prevents the tarnishing of the external threads of the thread sheet, larger than the diameter of the imaginary envelope of the thread sheet, and in such a way that the ring opening in its respective dimensions increases in relation to the size of the spinneret their summary of conically converging cords of thread is adapted at the location of the ring concerned.

An Hand der beigegebenen Zeichnung wird die Erfindung näher erläutert. Es zeigt:

  • Fig. 1 erfindungsgemäße Spinnanlage, in der Spinnschachtachse geschnitten;
  • Fig. 2 Verteilerteil des Anblaskastens, in der Spinnschachtachse geschnitten.
The invention is explained in more detail with reference to the accompanying drawing. It shows:
  • 1 spinning plant according to the invention, cut in the spinning shaft axis;
  • Fig. 2 distributor part of the blow box, cut in the spinning shaft axis.

Der obere, an die Spinndüse 1 anschließende Teil des Spinnschachtes 3 besteht aus dem perforierten Teilabschnitt 6 und einem kurzen anschließenden nichtperforierten Abschnitt. Es kann zusätzlich im unmittelbaren Anschluß an die Spinndüse auch ein weiterer nichtperforierter Abschnitt vorgesehen sein, der der Nachheizung der aus der Spinndüse austretenden Fäden dient. Diese Teile des Spinnschachtes 3 werden vom Anblaskasten 4 mit dem Luftzufuhrkanal 5 umgeben. Der Anblaskasten 4 ist seinerseits in den unteren Eintrittsteil 18 und den oberen, durch den aus einem siebförmigen Verteilereinsatz bestehenden Verteilerkastenboden 17 vom Eintrittsteil 18 getrennten Austrittsteil oder Verteilerkasten 19 unterteilt; die Perforation des Teilabschnitts 6 des Spinnschachts 3 verläuft nur im Verteilerkasten 19. Zwar kann sie noch andere Abschnitte des Spinnschachts umfassen, nicht jedoch den Abschnitt, der den Eintrittsteil 18 durchdringt; dieser darf keine Perforation aufweisen.The upper part of the spinning shaft 3 adjoining the spinneret 1 consists of the perforated section 6 and a short subsequent non-perforated section. In addition, a further non-perforated section can be provided in the direct connection to the spinneret, which serves to reheat the threads emerging from the spinneret. These parts of the spinning shaft 3 are surrounded by the blow box 4 with the air supply duct 5. The blow box 4 is in turn subdivided into the lower inlet part 18 and the upper outlet part or distribution box 19 which is separated from the inlet part 18 by the distributor box base 17 consisting of a sieve-shaped distributor insert; the perforation of the section 6 of the spinning shaft 3 runs only in the distribution box 19. Although it can comprise other sections of the spinning shaft, the section that penetrates the inlet part 18 cannot; this must have no perforation.

Wie aus der Fig. 1 ersichtlich, ist der obere Teil des Spinnschachts zur Durchführung von Düsenwechseln und dergl. absenkbar. Hierzu ist der Anblaskasten 4 über einen Tragarm 8 mit einem auf einer Säule 10 laufenden Führungsschlitten 9 verbunden. Die Säule 10 ist über die Traverse 11 an der Gebäudewand verankert. Durch ein Gegengewicht 13 wird der obere Teil des Spinnschachts zusammen mit dem Anblaskasten 4 in seiner jeweiligen Lage gehalten.As can be seen from FIG. 1, the upper part of the spinning shaft can be lowered to carry out nozzle changes and the like. For this purpose, the blow box 4 is connected via a support arm 8 to a guide carriage 9 running on a column 10. The column 10 is anchored to the wall of the building via the cross member 11. The upper part of the spinning shaft is held in its respective position together with the blow box 4 by a counterweight 13.

Die in Fig. 1 angedeuteten Mittel 20 zum Einengen des freien Spinnschachtquerschnitts sind in Fig. 2 deutlicher zu erkennen. Zwar sind in der Zeichnung neun Ringe 20, in gleichbleibendem Abstand 21 voneinander, vorgesehen, dies bedeutet jedoch nicht, daß eine solche Anzahl immer erforderlich wäre; in manchen Fällen kan ein einzelner Ring 20 bereits genügen, wenn sich auch ergeben hat, daß in der Regel wenigstens zwei solcher Ringe 20 vorgesehen werden sollten. Die günstigste Anzahl hängt von den jeweiligen örtlichen Gegebenheiten wie Einzelfadenzahl, Einzelfadentiter, Material, Spinngeschwindigkeit, usw. ab. Bei mehreren Ringen kann der gegenseitige Abstand gleich sein, er kann aber auch beispielsweise in Fadenlaufrichtung zunehmen.The means 20 indicated in FIG. 1 for narrowing the free spinning shaft cross section can be seen more clearly in FIG. 2. Although nine rings 20 are provided in the drawing at a constant distance 21 from one another, this does not mean that such a number would always be required; in some cases, a single ring 20 may be are already sufficient, even if it has been found that generally at least two such rings 20 should be provided. The cheapest number depends on the local conditions such as the number of single threads, single thread titer, material, spinning speed, etc. If there are several rings, the mutual distance can be the same, but it can also increase, for example, in the direction of the thread.

Wie in Fig. 2 angedeutet, sind die Durchmesser 23 der einzelnen Ringöffnungen 22 an die nach der Stelle ihrer Zusammenführung hin enger werdende Form der Fadenschar angepaßt; auf jeden Fall soll der Durchmesser 23 der einzelnen Ringöffnung 22 möglichst eng an die örtliche Abmessung der Fadenschar angepaßt und allenfalls nur soviel größer sein, daß gerade Berührung verhindert wird.As indicated in FIG. 2, the diameters 23 of the individual ring openings 22 are adapted to the shape of the thread sheet which becomes narrower after the point at which they are brought together; in any case, the diameter 23 of the individual ring opening 22 should be adapted as closely as possible to the local dimension of the thread sheet and at most only be so much larger that straight contact is prevented.

Durch die Anordnung der Ringe wird die Luftführung in dem Spinnschaft 3 vergleichmäßigt. Die Luft tritt in allen axial hintereinander liegenden Zonen radial in das Faserbündel ein. Die ins Innere des Faserbündels gelangte, erwärmte Luft wird im Zentrum des Faserbündels axial abgeführt und kann nicht radial expandieren und dadurch den Kontakt des Faserbündels mit frischer Luft streckenweise behindern.The air flow in the spinning shaft 3 is made more uniform by the arrangement of the rings. The air radially enters the fiber bundle in all axially successive zones. The heated air that has entered the interior of the fiber bundle is axially discharged in the center of the fiber bundle and cannot expand radially, thereby hampering the contact of the fiber bundle with fresh air in places.
