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.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.

Bei einer bekannten Anordnung dieser Art (DE-OS 27 41 859 = US-PS 4 133 353) 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 a known arrangement of this type (DE-OS 27 41 859 = US-PS 4 133 353) 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 of the first nozzle can largely escape into the environment . This allows the feed material to be deflected into the environment before entering the following nozzle. This is particularly disadvantageous 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 der ersten Düse und der Eintrittsöffnung der folgenden Düse ein Führungskanal von -- im Vergleich zu dem Querschnitt A der Fadenkanäle der beiden Düsen -- wesentlich grösserem Querschnitt B 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 first nozzle and the inlet opening of the following nozzle a guide channel of - in comparison to the cross section A of the thread channels of the two nozzles - a substantially larger cross section B is arranged. This makes it possible to have a larger central area to achieve a 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 break, 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.

The drawing shows an inventive nozzle arrangement for an air jet weaving machine.
  • 1 is a section through a first embodiment,
  • 1a shows a different position of the parts according to FIG. 1,
  • FIG. 1b explains a speed diagram belonging to FIG. 1
  • 2 and 3 illustrate modified embodiments and
  • Fig. 4 shows yet another type.

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. Der Düsenkörper 4 enthält einen Fadenkanal 8 für den von einer nicht dargestellten Schussfaden-Vorratsspule kommenden Schussfaden 7 und mehrere, um ihn herum angeordnete Luftzuführungskanäle 9. Diese erhalten Luft durch einen Zuführungskanal 11.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. The nozzle body 4 contains a thread 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. These receive air through a supply channel 11.

Auf das Ausströmrohr 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 Acht-fache beträgt.On the outlet pipe 12 of each nozzle 2, 3, its cross section denoted by A, a guide tube 14 is pushed on with the interposition of a sealing ring 13, the cross section B of which is considerably larger than the cross section A, for example 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 crr 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 there is only a small distance C of e.g. one to two millimeters.

Die Geschwindigkeit der das Rohr 12 an der Austrittsöffnung 21 der Düse 2 verlassenden Luft wird durch die Vergrösserung des Querschnitts von A auf B stark abgesenkt. Dadurch kann en relativ grosser Mittelbereichlin 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 tube 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 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 beispielsweise auch in Fig. 1 soweit nach links geschoben werden, dass es gemäss Fig. 1a 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.The guide tube 14 of the nozzle 2 can, for example, 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. 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. 1a 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 two rows of perforation holes 27 only in the end region 26. A portion of the air is able to escape into the environment through them, even if the tube 14 according to FIG is pushed out that it projects into the inlet opening 17 of the nozzle 3 or sits on the inflow funnel 24.

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 Ausführungsfrom 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.3, the guide tube 14 has perforation holes 27 along its entire length. This allows the amount of air exiting through the tube 14 into the environment to be adjusted.

Bei dem Ausführungsbeispiel nach Fig. 4 ist zwischen dem Fadenkanal 12 bzw. der Austrittsöffnung 21 der Düse 2 und der Eintrittsöffnung 17 der Düse 3 ein auf einem Halter 31 ortsfest angeordnetes Führungsrohr 14a vorgesehen. Sein Querschnitt F ist wesentlich grösser als der Querschnitt A des Kanals 12 der Düse 2. Auch auf diese Weise lässt sich erreichen, dass ein relativ grosser, mittlerer Strömungsbereich von praktisch konstanter Geschwindigkeit in dem Rohr 14a entsteht.In the exemplary embodiment according to FIG. 4, a guide tube 14a which is arranged in a stationary manner on a holder 31 is provided between the thread channel 12 or the outlet opening 21 of the nozzle 2 and the inlet opening 17 of the nozzle 3. Its cross-section F is substantially larger than the cross-section A of the channel 12 of the nozzle 2. Also in this way it can be achieved that a relatively large, middle flow area of practically constant speed is created in the pipe 14a.

Gegebenenfalls können die Düsen 2,3 wie auch das Führungsrohr 14a aufgrund von Führungen 41,42,43 in dem Gestell 1 gegeneinander verschiebbar und einstellbar angeordnet sein (Pfeile 44,45,46). Das Rohr 14a kann dann z.B. mit seinem Ende 14b über den Fadenkanal 12 unter Spiel 34 hinwegragen.If necessary, the nozzles 2, 3 and also the guide tube 14a can be arranged such that they can be displaced and adjusted relative to one another due to guides 41, 42, 43 in the frame 1 (arrows 44, 45, 46). The pipe 14a can then e.g. project with its end 14b over the thread channel 12 under play 34.

Durch den Schlitz 34 kann eine gewisse Menge Luft in die Umgebung austreten bzw. in das Rohr 14a eintreten.A certain amount of air can escape through the slot 34 or enter the tube 14a.

Bei den verschiedenen Varianten 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.In the different variants, the conditions with regard to the guidance of the weft thread 7 between the Change nozzles 2, 3 on the one hand and the air entraining it on the other hand in various ways. The guide tube between the two nozzles can also be set to optimal conditions by the operating personnel, particularly during weaving operation.
