Abstract

The nozzle assembly employs a guide tube between successive nozzles to reliably convey a yarn from one nozzle to the other. The guide tube provides for a practically constant flow of velocity in a central zone so that the yarn is not deflected from the central zone. The guide tube can be axially adjusted along the outflow tube of one nozzle assembly.

Description

Die Erfindung betrifft eine Düsenanordnung für eine Webmaschine mit Strahl-, z.B. Luftstrahleintrag, mit mindestens zwei hintereinander geschalteten Eintragsdüsen für das einzutragende, fadenförmige Material, wobei jede Eintragsdüse einen vor einer Strahleinleitstelle angeordneten Zuleitkanal und einen nach der Strahleinleitstelle angeordneten Ableitkanal aufweist.The invention relates to a nozzle arrangement for a loom with jet, e.g. Air jet entry, with at least two entry nozzles connected in series for the thread-like material to be inserted, each entry nozzle having an inlet duct arranged in front of a jet inlet point and an outlet channel arranged after the jet inlet point.

Bei bekannten Anordnungen dieser Art (DE-OS-27 41 859=US-PS-4 133 353, DE-OS-29 00 144) besteht zwischen der Austrittsöffnung der ersten Düse und der Eintrittsöffnung der folgenden Düse freier Raum, so dass der Luftstrahl der ersten Düse weitgehend in die Umgebung austreten kann, Dadurch kann das Eintragsmaterial vor dem Eintritt in die folgende Düse in die Umgebung abgelenkt werden. Dies ist insbesondere beim Einfädeln eines neuen Schussfadens durch die verschiedenen Düsen der Anordnung nachteilig.In known arrangements of this type (DE-OS-27 41 859 = US-PS-4 133 353, DE-OS-29 00 144) there is free space between the outlet opening of the first nozzle and the inlet opening of the following nozzle, so that the air jet the first nozzle can largely escape into the environment. As a result, the feed material can be deflected into the environment before entering the following nozzle. This is disadvantageous in particular when threading a new weft thread through the various nozzles of the arrangement.

Der Erfindung liegt die Aufgabe zugrunde, eine besonders in dieser Hinsicht verbesserte Düsenanordnung zu schaffen.The invention has for its object to provide a nozzle arrangement which is particularly improved in this regard.

Die Erfindung besteht darin, dass zwischen der Austrittsöffnung des Ableitkanals der ersten Düse und der Eintrittsöffnung des Zuleitkanals der folgenden Düse ein Führungskanal von-im Vergleich zu dem Querschnitt des Ableitkanales der ersten Düse-mindestens etwa vierfachem Querschnitt unter Dichtung mit dem Ableitkanal der ersten Düse angeordnet ist. Hierdurch wird es möglich, einen flächenmässig grösseren Mittelbereich von praktisch konstanter Geschwindigkeit in dem Führungskanal zu erzielen. Der Faden wird praktisch nur in diesem Mittelbereich vorwärts getragen. Die eine Geschwindigkeitsabnahme aufweisenden Randbereiche des Führungskanales sind relativ zu dem Mittelbereich von geringer Erstreckung. Diese Randbereiche vermögen praktisch keinen Einfluss auf den Faden auszuüben, so dass dieser nicht aus dem Mittelbereich abgelenkt wird. Der Webbetrieb und auch das Einfädeln eines neuen Schussfadens etwa nach einem Schussfadenbruch werden dadurch begünstigt. Die Luft kann in dem Bereich zwischen den beiden Düsen geführt werden.The invention consists in that between the outlet opening of the discharge duct of the first nozzle and the inlet opening of the feed duct of the following nozzle, a guide duct of at least approximately four times the cross-section under sealing with the discharge duct of the first nozzle is arranged in comparison with the cross section of the discharge duct of the first nozzle is. This makes it possible to achieve a larger central area of practically constant speed in the guide channel. The thread is practically carried forward only in this central area. The edge regions of the guide channel which show a decrease in speed are relatively small in relation to the central region. These edge areas have practically no influence on the thread, so that it is not deflected from the middle area. The weaving operation and also the threading of a new weft thread, for example after a weft thread breakage, are thereby favored. The air can be led in the area between the two nozzles.

Weitere Merkmale ergeben sich aus der folgenden Beschreibung von Ausführungsbeispielen in Verbindung mit der Zeichnung und den Ansprüchen.Further features result from the following description of exemplary embodiments in conjunction with the drawing and the claims.

Die Zeichnung zeigt eine erfindungsgemäss ausgebildete Düsenanordnung für eine Luftstrahlwebmaschine.

  • Fig. 1 ist ein Schnitt durch eine erste Ausführungsform,
  • Fig. 1 a zeigt eine andere Position der Teile nach Fig. 1,
  • Fig. 1b erläutert ein zu Fig. 1 gehörendes Geschwindigkeitsdiagramm und
  • Fig. 2 und 3 veranschaulichen abgewandelte Ausführungsformen.
The drawing shows an inventive nozzle arrangement for an air jet weaving machine.
  • 1 is a section through a first embodiment,
  • 1 a shows another position of the parts of FIG. 1,
  • FIG. 1b explains a speed diagram belonging to FIG. 1 and
  • 2 and 3 illustrate modified embodiments.

Ein Gehäuse 1 enthält zwei als Ganzes mit 2,3 bezeichnete, hintereinander geschaltete Düsen. Jede Düse 2,3 enthält einen Düsenkörper 4, der unter Zwischenlage von Gummidichtungen 5 in eine Bohrung 6 des Gehäuses 1 eingeschoben ist.A housing 1 contains two nozzles, which are designated as a whole by 2, 3 and are connected in series. Each nozzle 2, 3 contains a nozzle body 4 which is inserted into a bore 6 of the housing 1 with the interposition of rubber seals 5.

Der Düsenkörper 4 enthält einen Zuleitkanal 8 für den von einer nicht dargestellten Schussfaden-Vorratsspule kommenden Schussfaden 7 und mehrere, um ihn herum angeordnete Luftzuführungskanäle 9, die an einer Einleitstelle 70 münden. Die Kanäle 9 erhalten Luft durch einen Zuführungskanal 1. In Strömungs- bzw. Fadenlaufrichtung nach der Lufteinleitstelle 70 ist ein Ableitkanal 12 angeordnet.The nozzle body 4 contains a feed channel 8 for the weft thread 7 coming from a weft thread supply bobbin, not shown, and a plurality of air supply channels 9 arranged around it, which open out at an inlet point 70. The channels 9 receive air through a supply channel 1. A discharge channel 12 is arranged in the flow or thread running direction after the air inlet point 70.

Auf den Ableitkanal 12 jeder Düse 2,3, dessen Querschnitt mit A bezeichnet ist, ist unter Zwischenlage eines Dichtungsringes 13 ein Führungsrohr 14 aufgeschoben, dessen Querschnitt B im Vergleich zu dem Querschnitt A wesentlich grösser ist, z.B. das Vier- bis Achtfache beträgt.On the discharge channel 12 of each nozzle 2, 3, the cross section of which is designated A, a guide tube 14 is pushed with the interposition of a sealing ring 13, the cross section B of which is significantly larger than the cross section A, e.g. is four to eight times.

Das auf der Düse 2 befindliche, gemäss Pfeil 61 axial verschiebbare Führungsrohr 14 kann z.B. in Fig. 1 soweit nach links geschoben sein, dass zwischen seiner Austrittsöffnung 16 und der Eintrittsöffnung 17 der folgenden Düse 3 nur ein geringer Abstand C von z.B. ein bis zwei Millimeter besteht.The guide tube 14 located on the nozzle 2 and axially displaceable according to arrow 61 can e.g. 1 pushed so far to the left that between its outlet opening 16 and the inlet opening 17 of the following nozzle 3 only a small distance C of e.g. one to two millimeters.

Die Geschwindigkeit der den Ableitkanal 12 an der Austrittsöffnung 21 der Düse 2 verlassenden Luft wird durch die Vergrösserung des Querschnitts von A auf B stark abgesenkt. Dadurch kann ein relativ grosser Mittelbereich M in dem Querschnitt B entstehen, welcher praktisch konstante Geschwindigkeit aufweist. Die Randbereiche sind im Vergleich dazu vernachlässigbar klein. Dies wirkt sich auf die Fadenführung stabilisierend aus; der Faden hat eine verstärkte Tendenz im Mittelbereich zu verbleiben. Vgl. die entsprechenden Geschwindigkeitspfeile in dem Diagramm nach Fig. 1b. Ein Teil der Luft kann bei C in die Umgebung austreten. Der restliche Teil gelangt in die Einströmöffnung 17 der folgenden Düse 3.The speed of the air leaving the discharge duct 12 at the outlet opening 21 of the nozzle 2 is greatly reduced by increasing the cross section from A to B. This can result in a relatively large central region M in cross section B, which has a practically constant speed. In comparison, the marginal areas are negligibly small. This has a stabilizing effect on the thread guide; the thread has an increased tendency to remain in the middle area. See the corresponding speed arrows in the diagram of Fig. 1b. Part of the air can escape into the environment at C. The remaining part enters the inflow opening 17 of the following nozzle 3.

In entsprechender Weise kann das bei der Düse 3 befindliche Führungsrohr 14 verhältnismässig nahe an das durch die gemäss Pfeil 62 bewegten Kettfäden 22 gebildete Webfach 20 herangeführt werden, wo ein Gewebe 23 durch Eintragen der Schussfäden 7 erzeugt wird.In a corresponding manner, the guide tube 14 located at the nozzle 3 can be brought relatively close to the shed 20 formed by the warp threads 22 moved according to arrow 62, where a fabric 23 is produced by inserting the weft threads 7.

Das Führungsrohr 14 von Düse 2 kann beispeilsweise auch in Fig. 1 soweit nach links geschoben werden, dass es gemäss Fig. 1 a in die Einströmöffnung 17 der Düse 3 hineinragt oder auf dem Einströmtrichter 24 aufsitzt. In diesem Fall kann keine oder nur sehr wenig Luft in die Umgebung austreten.For example, the guide tube 14 of nozzle 2 can also be pushed to the left in FIG. 1 to such an extent that it protrudes into the inflow opening 17 of the nozzle 3 or sits on the inflow funnel 24 according to FIG. 1 a. In this case, little or no air can escape into the environment.

Bei dem Beispiel nach Fig. 2 besitzt das Führungsrohr 14 lediglich in dem Endbereich 26 zwei Reihen von Perforationslöchern 27. Durch sie vermag ein Anteil der Luft in die Umgebung auszutreten, und zwar auch dann, wenn das Rohr 14 gemäss Fig. 1 soweit nach links ausgeschoben ist, dass es in die Eintrittsöffnung 17 der Düse 3 hineinragt oder auf dem Einströmtrichter 24 aufsitzt.In the example according to FIG. 2, the guide tube 14 has only in the end region 26 two rows of perforation holes 27. A portion of the air is able to escape into the environment through them, even if the tube 14 according to FIG. 1 is pushed out to the left so far that it protrudes into the inlet opening 17 of the nozzle 3 or on the Inflow funnel 24 sits.

Bei der Bauart nach Fig. 2 besitzt das Führungsrohr 14 und das Rohr 12 Gewinde 28, wodurch das Rohr 14 axial verschiebbar und einstellbar ist.2, the guide tube 14 and the tube 12 have threads 28, as a result of which the tube 14 is axially displaceable and adjustable.

Bei der Ausführungsform nach Fig. 3 besitzt das Führungsrohr 14 auf seiner ganzen Länge Perforationslöcher 27. Hierdurch lässt sich die Menge der durch das Rohr 14 hindurch in die Umgebung austretenden Luft einstellen.In the embodiment according to FIG. 3, the guide tube 14 has perforation holes 27 along its entire length. As a result, the amount of air exiting through the tube 14 into the environment can be adjusted.

Bei den verschiedenen Verianten lassen sich die Verhältnisse bezüglich der Führung des Schussfadens 7 zwischen den Düsen 2,3 einerseits und der ihn mitnehmenden Luft andererseits in verschiedener Hinsicht verändern. Das Führungsrohr zwischen den beiden Düsen kann insbesondere auch während des Webbetriebes vom Bedienungspersonal auf optimale Verhältnisse eingestellt werden.With the different versions, the conditions with regard to the guidance of the weft thread 7 between the nozzles 2, 3 on the one hand and the air entraining it on the other hand can be changed in various respects. The guide tube between the two nozzles can also be set to optimal conditions by the operating personnel, particularly during weaving operation.
