Abstract

Nozzle arrangement for a weaving loom with an air-jet feed of the weft yarn into the shed. A plurality of nozzles, for example three nozzles (1, 2, 3), are connected in series and are connected respectively to one another by means of a continuous tube (15, 18). The cross-section (E) at the outflow channel (8) of a following nozzle (2) is larger than the cross-section (D) at the outflow channel (7) of a preceding nozzle (1), so that the air fed in at the second nozzle can be conveyed further together with the air coming from the first nozzle. The length of travel of the weft yarn (13) where the blowing air can act on the yarn and exert driving forces thereby becomes greater. At the same time, the possibility that air will escape between the individual nozzles into the environment is prevented, so that a compressed-air source of relatively low power can be used. <IMAGE>

Description

Die Erfindung bezieht sich auf 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 bisherigen Anordnung dieser Art (CH-PS 441 148) ist zwischen zwei hintereinander geschaltete Eintragsluftdüsen ein perforierter Schlauch geschaltet, durch den die Luft der ersten Düse auf dem Weg zur zweiten Düse sukzessive entweichen kann. Dadurch entsteht der Nachteil, dass auf dem Weg zwischen der ersten und der folgenden Düse nur relativ geringe Mitnahmewirkung seitens der eingeblasenen Luft auf den einzutragenden Faden entstehen kann. Auch geht die durch die Löcher des Verbindungsschlauches entweichende Luft verloren. Es wird also gesamthaft in den beiden Düsen relativ viel Druckluft verbraucht, so dass auch die Druckluftquelle entsprechend leistungsfähig ausgebildet werden muss.In a previous arrangement of this type (CH-PS 441 148), a perforated hose is connected between two intake air nozzles connected in series, through which the air from the first nozzle can gradually escape on the way to the second nozzle. This creates the disadvantage that on the path between the first and the following nozzle there can be only a relatively slight entraining effect on the thread to be introduced on the part of the air blown in. The air escaping through the holes in the connecting hose is also lost. Overall, a relatively large amount of compressed air is consumed in the two nozzles, so that the compressed air source must also be appropriately powerful.

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 der Querschnitt der Ausströmöffnung einer nachfolgenden Düse grösser ist als derjenige einer vorhergehenden Düse und dass die beiden Düsen durch einen nach aussen abgeschlossenen Kanal miteinander verbunden sind. (Im folgenden ist beispielsweise eine Luftstrahldüsenanordnung und ein Faden als einzutragendes Material angenommen.) Auf diese Weise lässt sich vermeiden, dass zwischen zwei aufeinanderfolgenden Düsen die durch die vorgeschaltete Düse eingeblasene Luft ganz oder teilweise verloren geht. Dadurch wird es möglich, dass die zwischen zwei aufeinander folgenden Düsen strömende Luft auf dem ganzen Weg zwischen den beiden Düsen eine gleichmässige Mitnahmewirkung auf den einzutragenden Faden ausübt. Konzentrierte Angriffspunkte mit stossförmiger Mitnahmewirkung können vermieden werden.The invention consists in that the cross-section of the outflow opening of a subsequent nozzle is larger than that of a preceding nozzle and that the two nozzles are connected to one another by a channel which is closed off from the outside. (The following is an example of an air jet nozzle arrangement and a thread as a measure to be entered assumed.) In this way it can be avoided that between two successive nozzles the air blown through the upstream nozzle is lost in whole or in part. This makes it possible for the air flowing between two successive nozzles to exert a uniform entraining effect on the thread to be inserted all the way between the two nozzles. Concentrated points of attack with impact-like entrainment effect can be avoided.

Es kann eine besonders hohe Fadenbeschleunigung mit relativ wenig Druckluft erzeugt werden, wie es für Webmaschinen mit hoher Drehzahl erwünscht ist. Da keine Luft zwischen den Düsen verloren geht, ist mit einer Druckluftquelle von relativ geringer Leistung auszukommen. Schliesslich kann durch den durchgehenden Verbindungskanal zwischen zwei aufeinanderfolgenden Düsen das Eindringen von im Websaal vorhandenem Faserflug oder anderer Verschmutzungen vermieden werden.A particularly high thread acceleration can be generated with relatively little compressed air, as is desired for high-speed weaving machines. Since no air is lost between the nozzles, a compressed air source of relatively low output can be used. Finally, the continuous connection channel between two successive nozzles prevents the ingress of fiber fly or other contaminants present in the weaving room.

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 eine erste Anordnung in einem schematisierten Schnitt,
  • Fig. 2 zeigt eine Abwandlung eines zugehörigen Details.
The drawing shows an inventive nozzle arrangement for an air jet weaving machine.
  • 1 is a first arrangement in a schematic section,
  • Fig. 2 shows a modification of an associated detail.

In drei gesamthaft mit 1 - 3 bezeichnete Druckluftdüsen wird jeweils bei 4 Druckluft gemäss Pfeil 49 eingeblasen. Dies kann intermittierend entsprechend dem Schusseintrag erfolgen. Jede Düse 1 - 3 enthält einen ringförmigen Verteilkanal 5, aus dem mehrere z.B. zwei, drei oder vier Kanäle 6 weggeführt sind. Durch sie gelangt die eingeleitete Druckluft gemäss Pfeilen 50 in die Ausströmöffnung 7 bzw. 8 bzw. 9 der drei Düsen.Air is blown into three compressed air nozzles, labeled 1 - 3, at 4 compressed air according to arrow 49. This can be done intermittently according to the weft insertion. Each nozzle 1-3 contains an annular distribution channel 5, from which several, for example, two, three or four channels 6 are led away. The introduced one passes through it Compressed air according to arrows 50 into the outflow opening 7 or 8 or 9 of the three nozzles.

Der in das Webfach einzutragende Schussfaden 30 gelangt von einer Vorratsspule 10 gemäss Pfeil 11 in eine trichterförmige Einlauföffnung 12 der Düse 1 und wird in dem Zulaufraum 13 von der aus den Kanälen 6 kommenden Druckluft erfasst. Der Querschnitt des Ausströmkanales 7 der Düse 1 ist mit D bezeichnet. Er ist gleich dem Querschnitt des Verbindungsrohres 15, durch das die Ausströmöffnung 7 der Düse 1 mit der Einlauföffnung 16 der Düse 2 verbunden ist. Das Rohr 15 bildet einen durchgehenden Kanal. Zwischen Düse 1 und 2 tritt keine Druckluft in die Umgebung aus.The weft thread 30 to be inserted into the shed goes from a supply spool 10 according to arrow 11 into a funnel-shaped inlet opening 12 of the nozzle 1 and is captured in the inlet space 13 by the compressed air coming from the channels 6. The cross section of the outflow channel 7 of the nozzle 1 is denoted by D. It is equal to the cross section of the connecting pipe 15 through which the outflow opening 7 of the nozzle 1 is connected to the inlet opening 16 of the nozzle 2. The tube 15 forms a continuous channel. No compressed air escapes into the environment between nozzles 1 and 2.

Der mit gleichem Querschnitt D versehene Einströmkanal 17 der Düse 2 mündet in den Verteil- bzw. Mischraum 13, in dem die über die Kanäle 6 der Düse 2 eingeleitete, zusätzliche Druckluft mit der aus Kanal 17 kommenden Luft der Düse 1 gemischt und gemeinsam in den Ausströmkanal 8 der Düse 2 geleitet wird. Dieser besitzt den Querschnitt E, der gleich dem Querschnitt des in Düse 2 mit der nachgeschalteten Düse 3 verbindenden Rohres 18 ist. Der Querschnitt E ist grösser als der Querschnitt D des Verbindungsrohres 15, so dass die von Düse 1 und Düse 2 kommende Luft gemeinsam weiterströmen kann.The inflow duct 17 of the nozzle 2 provided with the same cross section D opens into the distribution or mixing space 13, in which the additional compressed air introduced via the ducts 6 of the nozzle 2 mixes with the air from the duct 1 coming from duct 17 and together in the Outflow channel 8 of the nozzle 2 is passed. This has the cross section E, which is the same as the cross section of the pipe 18 connecting the nozzle 2 to the downstream nozzle 3. The cross section E is larger than the cross section D of the connecting pipe 15, so that the air coming from the nozzle 1 and nozzle 2 can continue to flow together.

Die Luft gelangt nunmehr in die Einströmöffnung 21 der folgenden Düse 3 und anschliessend im Kanal 22 dieser Düse bis zum Mischraum 13 von Düse 3. Hier wird die Luft in entsprechender Weise mit der über die Kanäle 6 der Düse 3 eingeleiteten Zusatzluft vermischt, um schliesslich in den Ausströmkanal 9 von Düse 3 zu gelangen. Dieser besitzt den Querschnitt F, der grösser ist wie der Querschnitt E der vorhergehenden Düse 2. Auch das Ausströmrohr 23 der Düse 3 besitzt den gleichen Querschnitt F. Der Faden 13 wird in der Zeichnung links aus dem Rohr 23 heraus in das nicht dargestellte Webfach der Webmaschine geleitet. Die Rohre 15,18,21 haben beispielsweise kreisförmigen Querschnitt.The air now enters the inflow opening 21 of the following nozzle 3 and then in the channel 22 of this nozzle to the mixing chamber 13 of the nozzle 3. Here, the air is mixed in a corresponding manner with the additional air introduced via the channels 6 of the nozzle 3, and finally in to get the outflow channel 9 from nozzle 3. This has the cross section F, which is larger than the cross section E of the preceding nozzle 2. The outflow pipe 23 of the nozzle 3 also has the same cross section F. The thread 13 is shown in the drawing on the left out of the pipe 23 in the shed, not shown Loom guided. The tubes 15, 18, 21 have a circular cross section, for example.

Der Querschnitt E von Ausströmkanal 8 der Düse 2 wird zweckmässig so gross gehalten, dass in ihm die aus Kanal 16 kommende Luft und die aus den Kanälen 6 zusätzlich eingeleitete Luft ohne wesentliche Druckänderung weiterströmen kann. Entsprechend wird bei Kanal 23 bzw. Querschnitt F vorgegangen. "The cross section E of the outflow duct 8 of the nozzle 2 is expediently kept so large that the air coming from the duct 16 and the air additionally introduced from the ducts 6 can continue to flow without a significant change in pressure. The same procedure is followed for channel 23 or cross section F. "

Wie aus der Zeichnung ersichtlich, ist an einem plattenförmigen Halter 31 des Webmaschinengestelles ein die Zuführungskanäle aufnehmender Düsenteil 32 befestigt, auf den unter Bildung einer entsprechenden, konischen Partie 33 ein Düsenblock 34 aufgesetzt ist. Dieser setzt sich in das Verbindungsrohr 15 zu folgenden Düse 2 fort und bildet bei dieser einen entsprechenden Düsenteil 35. Auf ihn ist wiederum unter Bildung einer konischen Partie 33 ein zur Düse 2 gehörender Düsenblock 36 aufgesetzt, der sich entsprechend in das Verbindungsrohr 18 und den Düsenteil 37 der Düse 3 fortsetzt. Auch hier ist wiederum unter Bildung einer konischen Partie 33 ein Düsenblock 38 aufgesetzt, der sich in das Ausströmrohr 23 fortsetzt.As can be seen from the drawing, a nozzle part 32 receiving the feed channels is fastened to a plate-shaped holder 31 of the weaving machine frame, on which a nozzle block 34 is placed to form a corresponding conical part 33. This continues into the connecting pipe 15 to the following nozzle 2 and forms a corresponding nozzle part 35 there. A nozzle block 36 belonging to the nozzle 2 is placed on it, forming a conical part 33, which correspondingly fits into the connecting pipe 18 and the nozzle part 37 of the nozzle 3 continues. Here too, a nozzle block 38 is placed, forming a conical section 33, which continues into the outflow pipe 23.

Bei einem abgewandelten Ausführungsbeispiel ist die Düse 3 fortgelassen und es sind nur die beiden Düsen 1 und 2 hintereinander geschaltet. Bei allen Ausführungsformen ist jeweils der Durchlassquerschnitt der Ausströmungsöffnung einer nachfolgenden Düse (z.B. der Querschnitt E der Ausströmöffnung 7 der Düse 2) grösser als der Durchlassquerschnitt der vorhergehenden Düse (z.B. der Durchlassquerschnitt D bei der Ausströmöffnung 7 der Düse 1).In a modified embodiment, the nozzle 3 is omitted and only the two nozzles 1 and 2 are connected in series. In all embodiments, the passage cross section of the outflow opening of a subsequent nozzle (e.g. the cross section E of the outflow opening 7 of the nozzle 2) is larger than the passage cross section of the previous nozzle (e.g. the passage cross section D at the outflow opening 7 of the nozzle 1).

Bei der Düsenanordnung kann die eingeblasene Druckluft von dem Mischraum 13 an bis zum links befindlichen Austrittsende des Rohres 23 Mitnahmekraft auf den Faden 13 ausüben. Infolge der durchgehenden Verbindungsrohre 15,18 kann auf dem ganzen Weg keine Luft entweichen.In the case of the nozzle arrangement, the blown-in compressed air can exert driving force on the thread 13 from the mixing space 13 to the outlet end of the tube 23 on the left. As a result of the continuous connecting pipes 15, 18, no air can escape all the way.

Bei einer abgewandelten Ausführungsform haben die Verbindungsrohre 15,18 nicht kreisförmigen, sondern z.B. quadratischen Querschnitt. Auch können die Rohre 15,18,23 mehr oder weniger in der Zeichnung nach links divergierend ausgebildet sein, vgl. Fig. 2. Es ist dann jeweils der unmittelbar am Austritt einer Düse zu messende Querschnitt, z.B. F in Betracht zu ziehen.In a modified embodiment, the connecting tubes 15, 18 do not have a circular shape, but rather, for example, quadra cross section. The tubes 15, 18, 23 can also be designed to diverge to the left more or less in the drawing, cf. Fig. 2. The cross-section to be measured directly at the outlet of a nozzle, for example F, must then be taken into account.

Bei einer weiteren Ausführungsform sind die Düsen 1 - 3 unmittelbar aneinandergesetzt, auf die Verbindungsrohre 15,18 kann dann verzichtet werden. In diesem Fall liegt die Ausströmöffnung 7 von Düse 1 unmittelbar an der Einströmöffnung 16 von Düse 2 und entsprechend die Ausströmöffnung 8 von Düse 2 unmittelbar an der Einströmöffnung 21 von Düse 3.In a further embodiment, the nozzles 1 - 3 are placed directly next to one another, and the connecting pipes 15, 18 can then be dispensed with. In this case, the outflow opening 7 of nozzle 1 is located directly on the inflow opening 16 of nozzle 2 and, accordingly, the outflow opening 8 of nozzle 2 is directly on the inflow opening 21 of nozzle 3.
