Description

Die Erfindung betrifft eine Eintragsdüsen-Anordnung einer Luftstrahlwebmaschine, mit mindestens zwei, wahlweise entsprechend einem Eintragsprogramm aktivierten, ausserhalb des Webfaches an einem Webmaschinenteil angeordneten Düsen für den Schusseintrag.The invention relates to an entry nozzle arrangement of an air jet weaving machine, with at least two nozzles for the weft insertion, which are optionally activated according to an entry program and are arranged outside of the shed on a weaving machine part.

Bei einer bisherigen Anordnung dieser Art (DE-OS-30 14 766 = US-PS-4 326 565 / TS 270) ist die Zweischuss-Düsenanordnung schwenkbar auf der Lade der Webmaschine angeordnet. Durch eine Steuervorrichtung wird jeweils diejenige Düse mit ihrem Luftausströmrohr in die Schusslinie verschwenkt, deren Schussfaden beim folgenden Schusseintrag benötigt wird.In a previous arrangement of this type (DE-OS-30 14 766 = US-PS-4 326 565 / TS 270) the two-shot nozzle arrangement is pivotally arranged on the drawer of the weaving machine. By means of a control device, the nozzle with its air outlet pipe is pivoted into the weft line, the weft thread of which is required for the following weft insertion.

Bei hohen Schusszahlen z. B. von 400 min-1 und mehr kann der Fall eintreten, dass die Verschwenkung der Düsen vor dem jeweiligen Schusseintrag nicht rasch genug vor sich geht. Auch können Störungen an den beweglichen Teilen der Schwenkeinrichtung eintreten.At high numbers of shots z. B. of 400 min- 1 and more, the case may occur that the pivoting of the nozzles before the respective weft insertion is not going on quickly enough. Faults can also occur on the moving parts of the swivel device.

Der Erfindung liegt die Aufgabe zugrunde, eine besonders in dieser Einsicht verbesserte Anordnung zu schaffen.The invention has for its object to provide a particularly improved arrangement in this insight.

Die Erfindung besteht darin, dass die beiden Düsen fest an dem sie tragenden Webmaschinenteil angebracht sind und dass eine der Düsen - mindestens in Eintragsposition der Teile - im wesentlichen parallel zur Schusslinie und die andere Düse unter einem geringen Neigungswinkel, vorzugsweise 1 - 5° zu dieser steht.The invention consists in that the two nozzles are firmly attached to the weaving machine part carrying them and that one of the nozzles - at least in the entry position of the parts - essentially parallel to the weft line and the other nozzle at a slight angle of inclination, preferably 1-5 ° to this stands.

Dadurch lässt sich erreichen, dass auf die bewegliche Anordnung der Mehrschuss-Eintragsdüsen überhaupt verzichtet werden kann. Die Düsen brauchen während des Betriebes weder verschwenkt, noch achsparallel verschoben zu werden. Damit lässt sich die Anordnung leicht für beliebig hohe Schusszahlen der Webmaschine verwenden. Bewegliche Teile wie auch die zugehörige Steuervorrichtung für die jeweilige Bewegung der Düsen vor dem Schusseintrag fallen fort.This makes it possible to dispense with the movable arrangement of the multi-shot entry nozzles at all. The nozzles do not need to be swiveled during operation or moved axially parallel. The arrangement can thus easily be used for any number of weft numbers of the loom. Moving parts as well as the associated control device for the respective movement of the nozzles before the weft insertion are eliminated.

Die Erfindung geht von der Erkenntnis aus, dass es - wie die Versuche ergaben - möglich ist, die eine Düse vorzugsweise parallel zur Schusslinie und die andere unter einem gewissen, geringen Winkel von beispielsweise 3° permanent einzubauen, so dass die beiden Düsen während des Betriebes nicht relativ zur Schusslinie bzw. zum Webblatt oder zu anderen Führungsmitteln für den Luftstrahl (z. B. Führungszähnen) bewegt werden müssen. Der geringe Neigungswinkel der zweiten Düse relativ zur ersten Düse ist besonders dann möglich, wenn die zweite Düse unter dem geringen Winkel gegen das Riet hin bläst und nicht etwa von ihm weg. Es kann z. B. ein sogenanntes Tunnelriet (profiliertes Riet) verwendet werden, dessen Tunnel aus der Profilierung der Lamellen gebildet ist.The invention is based on the knowledge that - as the tests have shown - it is possible to permanently install one nozzle, preferably parallel to the firing line, and the other at a certain, small angle of, for example, 3 °, so that the two nozzles during operation do not have to be moved relative to the line of fire or the reed or other guiding means for the air jet (e.g. guiding teeth). The small angle of inclination of the second nozzle relative to the first nozzle is particularly possible when the second nozzle blows against the reed at the small angle and not away from it. It can e.g. B. a so-called tunnel reed (profiled reed) can be used, the tunnel of which is formed from the profiling of the slats.

Auf der Lade 1 einer Luftstrahlwebmaschine ist ein aus profilierten Lamellen 2 bestehendes Riet 3 angebracht. Die Lamellen 2 bilden zusammen einen Eintragstunnel 4, in welchem die Schusseintragslinie 5 liegt.On the drawer 1 of an air jet weaving machine, a reed 3 consisting of profiled slats 2 is attached. The slats 2 together form an entry tunnel 4, in which the weft insertion line 5 lies.

An dem in Fig. 1 linken Ende der Lade 1 ist ein Träger 6 durch eine mit Schlitzen 7 versehene Verschraubung 8 verstellbar und feststellbar mit der Lade verbunden, wodurch sich der Abstand C (Fig. 2) verändern lässt. Auf dem Träger 6 ist mittels einer Schraube 11 ein Block 12 befestigt, auf dem zwei als Ganzes mit 15, 16 bezeichnete Schusseintragsdüsen fest angebracht sind. In der Düse 15 und dem zugehörigen, kreisrunden Querschnitt aufweisenden Mischrohr 17 ist ein in Fig. 1 strichpunktiert dargestellter Schussfaden 21, in der Düse 16 und dem zugehörigen Mischrohr 19 ist ein in Fig. 1 gestrichelt wiedergegebener Schussfaden 18 anderer Sorte, z. B. anderer Farbe, für einen Schusseintrag bereitgehalten. Die Schussfäden werden von Schussfadenspeichern 61, 62 abgezogen.At the left end of the drawer 1 in FIG. 1, a carrier 6 is adjustable and fixably connected to the drawer by a screw connection 8 provided with slots 7, as a result of which the distance C (FIG. 2) can be changed. On the carrier 6, a block 12 is fastened by means of a screw 11, on which two weft insertion nozzles, designated as a whole by 15, 16, are firmly attached. In the nozzle 15 and the associated circular cross-section having mixing tube 17 is a weft thread 21 shown in FIG. 1 in dash-dotted lines. B. different color, ready for a weft entry. The weft threads are drawn off from weft thread stores 61, 62.

Das freie, kreisrunden Querschnitt aufweisende Ende 17a ist, wie besonders aus Fig. 2 ersichtlich, parallel zur Schusslinie 5 gestellt, das freie, ebenfalls kreisrunden Querschnitt aufweisende Ende 19a des Mischrohres 19 steht unter einem Winkel A von etwa 3° zu der Schusslinie 5. Die beiden Enden 17a, 19a der Mischrohre 17, 19 sind in einer Führung 23 gehalten. Die beiden Ausströmöffnungen 51, 52 werden in der Regel so nahe wie möglich beieinander angeordnet, vorzugsweise berühren sie einander. Der Winkel A lässt sich mittels einer Verschraubung 45 einstellen, die einen an der Düse 16 angebrachten Flansch 48 mit einem sich senkrecht zur Zeichenebene von Fig. 1 erstreckenden Schlitz 47 aufweist.The free, circular cross-section end 17a, as can be seen particularly from FIG. 2, is placed parallel to the firing line 5, the free, likewise circular cross-section end 19a of the mixing tube 19 is at an angle A of approximately 3 ° to the firing line 5. The two ends 17a, 19a of the mixing tubes 17, 19 are held in a guide 23. The two outflow openings 51, 52 are generally arranged as close as possible to one another, preferably touching one another. The angle A can be set by means of a screw connection 45, which has a flange 48 attached to the nozzle 16 with a slot 47 extending perpendicular to the plane of the drawing in FIG. 1.

Während des Betriebes werden Lade 1 und Riet 3 sowie die gesamte mit 24 bezeichnete Düsenanordnung gemäss Pfeil 25 hin und her bewegt und es wird z. B. wechselweise entsprechend dem Schusseintragsprogramm ein Faden 18 oder 21 in das von den Kettfäden 42, 43 gebildete Webfach 41 eingetragen.During operation, drawer 1 and reed 3 as well as the entire nozzle arrangement designated 24 are moved back and forth according to arrow 25 and z. B. alternately according to the weft insertion program, a thread 18 or 21 entered in the shed 41 formed by the warp threads 42, 43.

Bei der Ausführungsform nach Fig. 4, 5 sind Block 12 und Führung 23 mit dem Gestell 48 der Webmaschine fest verbunden. Die Düsenanordnung 24a wird während des Webbetriebes nicht mit dem Riet 3 hin und her bewegt. Die Düsen bilden wiederum einen Winkel A von ca. 3° zueinander.In the embodiment according to FIGS. 4, 5, block 12 and guide 23 are firmly connected to the frame 48 of the weaving machine. The Nozzle arrangement 24a is not moved back and forth with reed 3 during weaving operation. The nozzles in turn form an angle A of approximately 3 ° to one another.

Bei den Beispielen nach Fig. 1 - 5 ist jeweils das Mischrohr der Düse 16 mit dem freien Ende 19a so gerichtet (Winkel A), dass es unter der Neigung von ca. 3° gegen den Grund 49 des Tunnels 4 bläst. Der Winkel A liegt in der horizontalen, in Fig. 1 mit E bezeichneten, strichpunktiert dargestellten, durch den Gewebeanschlag 50 und den Tunnelgrund 49 verlaufenden Ebene, d.h. in Fig. 2, 4 parallel zur Zeichenebene.In the examples according to FIGS. 1-5, the mixing tube of the nozzle 16 is directed with the free end 19a (angle A) such that it blows against the base 49 of the tunnel 4 at an inclination of approximately 3 °. The angle A lies in the horizontal plane, designated by E in FIG. 1, shown in dot-dash lines and running through the fabric stop 50 and the tunnel base 49, i.e. 2, 4 parallel to the plane of the drawing.

Während die Mischrohre 17, 19 bei den Beispielen nach Fig. 1 - 5 bei 28, 29 abgeknickt sind, sind die beiden Mischrohre 17b, 19b bei der Bauart nach Fig. 6 gerade ausgebildet.While the mixing tubes 17, 19 in the examples according to FIGS. 1-5 are kinked at 28, 29, the two mixing tubes 17b, 19b in the construction according to FIG. 6 are straight.

Bei der Ausführungsform nach Fig. 7 ist ein Dreischussmechanismus dargestellt, der eine dritte Düse mit einem Mischrohr 32 enthält. Dieses ist unter einem etwas grösseren Winkel B von ca. 4° gegen die Schusslinie 5 geneigt. Alle drei Mischrohre 17, 19, 32 der drei Düsen sind in der horizontalen, durch den Gewebeanschlag 50 und den Tunnelgrund 49 verlaufenden Ebene angeordnet, d.h. in Fig. 7 parallel zur Zeichenebene.In the embodiment according to FIG. 7, a three-shot mechanism is shown, which contains a third nozzle with a mixing tube 32. This is inclined at a somewhat larger angle B of approximately 4 ° against the firing line 5. All three mixing tubes 17, 19, 32 of the three nozzles are arranged in the horizontal plane running through the fabric stop 50 and the tunnel base 49, i.e. 7 parallel to the plane of the drawing.

Bei allen Bauarten steht das Ende 17a des Mischrohres 17 mindestens in der Eintragsposition der Teile oder aber in jeder Position d.h. auch während der Bewegung des Rietes 3 zum Gewebeanschlag 50 hin, jeweils parallel zur Schusslinie 5, das Ende 19a des Mischrohres 19 steht unter dem Winkel A zu dem Ende 17a des Mischrohres 17.In all types, the end 17a of the mixing tube 17 is at least in the entry position of the parts or in any position, i.e. also during the movement of the reed 3 towards the fabric stop 50, in each case parallel to the line of fire 5, the end 19a of the mixing tube 19 is at an angle A to the end 17a of the mixing tube 17.

Bei einer abgewandelten Ausführungsform ist statt eines Tunnelrietes ein Riet mit unprofilierten, geraden Lamellen verwendet und der Eintragstunnel wird durch vor dem Riet positionierte Führungszähne gebildet, in welche die Eintragsdüsen 15, 16 bzw. ihre Enden 17a, 19a blasen. Die Schusslinie 5 liegt dann innerhalb der genannten Führungszähne.In a modified embodiment, a reed with unprofiled, straight lamellae is used instead of a tunnel reed, and the entry tunnel is formed by guide teeth positioned in front of the reed, into which the entry nozzles 15, 16 or their ends 17a, 19a blow. The firing line 5 then lies within the guide teeth mentioned.
