Description

Die Erfindung betrifft eine Webmaschine, insbesondere eine Luftdüsenwebmaschine mit einer ein Webblatt tragenden Blattleiste, die zum Zwecke des Eintragens und Anschlagens von Schußfäden an die Anschlagkante eines Gewebes aus einer Eintragsposition in eine Anschlagposition und in umgekehrter Richtung um eine Längsachse einer Antriebs- oder Blattwelle gleichförmige Schwingbewegungen ausführt, mit einer ersten Düsenanordnung, die aus mehreren Hauptdüsen mit Blasrohr besteht, wobei die Hauptdüsen nach einem Ordnungssystem in einem Hauptdüsenblock aufgenommen sind und wobei der Hauptdüsenblock mit der die Schwingbewegungen ausführenden Blattleiste verbunden ist, und mit einer in Schußrichtung vor der ersten Düsenanordnung vorhandenen zweiten, stationären Düsenanordnung, die aus mehreren Vordüsen mit Blasrohr besteht, wobei der Fadenführungskanal jedes Blasrohres der jeweiligen Vordüse zum Zeitpunkt des Schußfadeneintrags fluchtend dem Fadenführungskanal des Blasrohres der jeweiligen Hauptdüse gegenüberliegt.The invention relates to a weaving machine, in particular an air-jet weaving machine with a leaf bar carrying a reed which, for the purpose of inserting and attaching weft threads to the stop edge of a fabric, from an insertion position into a stop position and in the opposite direction about a longitudinal axis of a drive or blade shaft, uniform oscillating movements carries out, with a first nozzle arrangement consisting of a plurality of main nozzles with a blowpipe, the main nozzles being accommodated in a main nozzle block according to an order system and the main nozzle block being connected to the blade strip which carries out the oscillating movements, and with a second one present in the weft direction in front of the first nozzle arrangement , stationary nozzle arrangement, which consists of several pre-nozzles with a blowpipe, the thread guide channel of each blowpipe of the respective pre-nozzle in alignment with the thread guide channel of the blowpipe at the time of the weft thread insertion opposite the respective main nozzle.

Bekannte Luftdüsenwebmaschinen besitzen für den Schußfadeneintrag einen Hauptdüsenblock mit mehreren darin nach einem bestimmten Ordnungssystem aufgenommenen, pneumatisch beaufschlagbaren Hauptdüsen mit Blasrohr bestimmter Länge, wobei das jeweilige Blasrohr auf den Schußeintragskanal eines Webblattes gerichtet ist. Der Hauptdüsenblock ist auf der das Webblatt tragenden Blattleiste der Webmaschine angeordnet und zwar so, daß der Hauptdüsenblock relativ zum Webblatt einstellbar ist.Known air jet weaving machines have a main nozzle block for the weft insertion with several main nozzles which can be acted upon pneumatically and with a blowing tube of a certain length, the main blowing tube being directed onto the weft insertion channel of a reed. The main nozzle block is arranged on the leaf bar of the weaving machine that carries the reed, in such a way that the main nozzle block is adjustable relative to the reed.

Zur Realisierung einer hohen Schußfadeneintragsleistung ist bekannt, jeder in dem Hauptdüsenblock integrierten Hauptdüse eine separat angeordnete Vordüse zuzuordnen, die in Eintragsrichtung des Schußfadens gesehen, vor der jeweiligen Hauptdüse beabstandet positioniert ist.To achieve a high weft insertion performance, it is known to assign each main nozzle integrated in the main nozzle block to a separately arranged pre-nozzle, which is positioned in front of the respective main nozzle as seen in the direction of insertion of the weft thread.

Die jeweilige Vordüse besitzt ein Blasrohr bestimmter Länge, das so in Richtung der jeweiligen Hauptdüse ausgerichtet ist, daß den Schußfaden schädigende Schußfadenablenkungen weitgehend vermieden werden.The respective front nozzle has a blowing tube of a certain length, which is oriented in the direction of the respective main nozzle in such a way that weft deflections which damage the weft thread are largely avoided.

Dabei ist das Ausrichten der jeweiligen Vordüse auf die betreffende Hauptdüse zeitaufwendig und zwar dann, wenn eine Vielzahl von Vordüsen auf eine betreffende Vielzahl von Hauptdüsen ausgerichtet werden muß.Aligning the respective pre-nozzle with the main nozzle in question is time-consuming, specifically when a large number of pre-nozzles have to be aligned with a relevant number of main nozzles.

Vor diesem Hintergrund ist es Aufgabe der Erfindung, eine Vordüsenanordnung vorzusehen, mit der das individuelle Ausrichten jeder Vordüse auf die zugehörige Hauptdüse entfällt und mit der Schußfadenablenkungen zwischen den Vor- und Hauptdüsen während des Schußfadeneintrages vermieden werden.Against this background, it is an object of the invention to provide a pre-nozzle arrangement with which the individual alignment of each pre-nozzle on the associated main nozzle is eliminated and with which weft deflections between the pre-and main nozzles during the weft insertion are avoided.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß die einzelnen Vordüsen mit Blasrohr nach einem dem Ordnungssystem der Hauptdüsen im Hauptdüsenblock entsprechenden Ordnungssystem in einem Vordüsenblock aufgenommen sind, welches Ordnungssystem ermöglicht, daß mit dem Ausrichten einer einzigen Vordüse auf die betreffende Hauptdüse alle übrigen Vordüsen beim Schußfadeneintrag auf die betreffenden Hauptdüsen ausgerichtet sind und zwar auch dann, wenn der Vordüsenblock auf einem von der Blattleiste unabhängigen, stationären Träger montiert ist.According to the invention the object is achieved in that the individual pre-nozzles with blowpipe are accommodated in a pre-nozzle block according to an order system corresponding to the order system of the main nozzles in the main nozzle block, which order system enables all other pre-nozzles to be inserted when the weft thread is inserted by aligning a single pre-nozzle to the relevant main nozzle the relevant main nozzles are aligned, even if the pre-nozzle block is mounted on a stationary support that is independent of the blade strip.

In weiterer Ausgestaltung der Erfindung kann der Vordüsenblock bei einem entsprechenden Ordnungssystem um seine Längsmittenachse drehbar auf dem mit der Webmaschine stationär verbundenen Träger angeordnet sein.
Ein bestimmtes Ordnungssystem der Vor- und Hauptdüsen ist z.B. dann gegeben, wenn die Mittenachsen der Düsen symmetrisch um die Längsmittenachse der Düsenblöcke auf einer Kreisbahn angeordnet sind.
In einem solchen Fall wird erreicht, daß durch Drehen des Vordüsenblockes um seine Längsmittenachse jede Vordüse einer beliebigen Hauptdüse zugeordnet werden kann.
Ein solches Vorgehen kann dann von Bedeutung sein, wenn Schußfäden verschiedener Qualität zu einem Gewebe verarbeitet werden und z.B. ein Schußfaden eine von der Hauptdüse abweichend konstruktiv ausgebildete Vordüse erfordert.
Innerhalb einer kurzen Zeitdauer ist dann die betreffende Vordüse der betreffenden Hauptdüse zuordenbar.
Erfindungswesentlich ist also, daß mit dem Ausrichten einer einzigen Vordüse auf die betreffende Hauptdüse alle übrigen Vordüsen auf ihre zugeordneten Hauptdüsen zwangsläufig fluchtend ausgerichtet sind.In a further embodiment of the invention, the pre-nozzle block can be arranged on a carrier connected to the weaving machine so that it can be rotated about its longitudinal center axis in a corresponding arrangement system.
A specific order of the pre and main nozzles is given, for example, if the center axes of the nozzles are arranged symmetrically about the longitudinal center axis of the nozzle blocks on a circular path.
In such a case it is achieved that by rotating the pre-nozzle block about its longitudinal center axis, each pre-nozzle can be assigned to any main nozzle.
Such a procedure can be of importance if weft threads of different quality are processed into a fabric and, for example, a weft thread requires a pre-nozzle which is designed differently from the main nozzle.
The relevant front nozzle can then be assigned to the relevant main nozzle within a short period of time.
It is essential to the invention that with the alignment of a single pre-nozzle on the Main nozzle in question all other pre-nozzles are necessarily aligned with their assigned main nozzles.

Mit der erfindungsgemäßen Lösung entfällt in vorteilhafter Weise das separate Ausrichten der Vielzahl von Vordüsen auf die betreffenden Hauptdüsen und es sind den Schußfaden schädigende Schußfadenablenkungen zwischen der Vor- und Hauptdüsenanordnung während des Schußfadeneintrags ausgeschlossen.With the solution according to the invention, the separate alignment of the plurality of pre-nozzles onto the main nozzles in question is advantageously eliminated and weft deflections damaging the weft thread between the pre-and main nozzle arrangement during the weft insertion are excluded.

Die Erfindung wird nachfolgend anhand eines in den Zeichnungen dargestellten Ausführungsbeispiels näher erläutert.The invention is explained in more detail below with reference to an embodiment shown in the drawings.

In Figur 1 ist auf der sogenannten Blattleiste 2, einer hier nicht weiter dargestellten Webmaschine 11, das nur teilweise dargestellte Webblatt 1 montiert.
In Schußrichtung 7 ist vor dem Webblatt 1 eine Hauptdüsenanordnung 5 mit der Blattleiste 2 lösbar verbunden dargestellt.
Die Blattleiste 2 schwingt periodisch zusammen mit dem Webblatt 1 zum Zwecke des Anschlagens von Schußfäden 3 an die hier nicht dargestellte Anschlagkante eines Gewebes um die Längsachse 4a einer Antriebs- oder Blattwelle 4.
Die Hauptdüsenanordnung 5 schwingt folglich auch im Bewegungsrhythmus der Blattleiste 2 um die Achse 4a.
Die Hauptdüsenanordnung 5 bildet bekanntermaßen einen Hauptdüsenblock 6 aus.
Die Hauptdüsen 5a sind in dem Hauptdüsenblock 6 nach einem bestimmten System angeordnet. Ein solches bestimmtes System wird in den Figuren 4, 6 und 8 gezeigt.
Die Hauptdüsen 5a sind mit einem Blasrohr 5b ausgerüstet.
Ein Fadenführungskanal 5b' durchzieht die Hauptdüsen 5a und das zugehörige Blasrohr 5b über deren Länge.
Der Hauptdüsenblock 6 und die freien Enden der Blasrohre 5b werden von einem Halter 13 getragen, der die Verbindung zur Blattleiste 2 herstellt.
Die Verbindungsmittel 14 sind symbolisch dargestellt.In FIG. 1, the weaving reed 1, which is only partially shown, is mounted on the so-called leaf bar 2, a weaving machine 11, which is not shown here.
In the weft direction 7, a main nozzle arrangement 5 is shown detachably connected to the blade strip 2 in front of the reed 1.
The blade bar 2 periodically swings together with the reed 1 for the purpose of attaching weft threads 3 to the stop edge of a fabric (not shown here) about the longitudinal axis 4a of a drive or blade shaft 4.
The main nozzle arrangement 5 consequently also swings about the axis 4a in the movement rhythm of the blade strip 2.
As is known, the main nozzle arrangement 5 forms a main nozzle block 6.
The main nozzles 5a are arranged in the main nozzle block 6 according to a certain system. Such a particular system is shown in Figures 4, 6 and 8.
The main nozzles 5a are equipped with a blow pipe 5b.
A thread guide channel 5b 'runs through the main nozzles 5a and the associated blow pipe 5b over their length.
The main nozzle block 6 and the free ends of the blowpipes 5b are carried by a holder 13, which establishes the connection to the sheet bar 2.
The connecting means 14 are shown symbolically.

Eine Vordüsenanordnung 8 ist in Schußrichtung 7 vor der Hauptdüsenanordnung 5 positioniert.
Die Vordüsenanordnung 8 ist stationär mit einem maschinenfesten Träger 12 verbunden.
Ein Halter 15 nimmt einen Vordüsenblock 9 auf, in dem erfindungsgemäß Vordüsen 8a mit Blasrohr 8b integriert sind und zwar nach einem Ordnungssystem, das dem der Hauptdüsen 5a im Hauptdüsenblock 6 entspricht. Der Halter 15 ist über symbolisch dargestellte Verbindungsmittel 16 mit dem Träger 12 verbunden.
Das Ordnungssystem der Vordüsen 8a im Vordüsenblock 9 zeigen die Figuren 3, und 7.A pre-nozzle arrangement 8 is positioned in front of the main nozzle arrangement 5 in the weft direction 7.
The pre-nozzle arrangement 8 is connected in a stationary manner to a carrier 12 fixed to the machine.
A holder 15 accommodates a pre-nozzle block 9, in which pre-nozzles 8a with a blowpipe 8b are integrated according to the invention, namely according to an order system which corresponds to that of the main nozzles 5a in the main nozzle block 6. The holder 15 is shown symbolically Connection means 16 connected to the carrier 12.
The organization system of the pre-nozzles 8a in the pre-nozzle block 9 is shown in FIGS. 3 and 7.

In Figur 2 befindet sich die Blattleiste 2 mit den Aufbauten 1, 5 und 13 in der Eintragsposition des Schußfadens 3. In dieser Position befindet sich permanent die Vordüsenanordnung 8, wodurch dann die Fadenführungskanäle 5b' und 8b' einander fluchtend gegenüberliegen.
Mit einer derartigen Anordnung ist unter anderem der Vorteil verbunden, daß zum Zeitpunkt des Schußfadeneintrages Ablenkungen der Schußfäden am Ausgang der Blasrohre 8b und am Eingang der Hauptdüsen 5a ausgeschlossen sind und daß, wie schon vorstehend erwähnt, aufgrund eines identischen Ordnungssystems zwischen den Haupt- und Vordüsen und der Vereinigung aller Vordüsen in einen Vordüsenblock, der Aufwand zum fluchtenden Einstellen der Vordüsen auf die Hauptdüsen minimiert ist.In FIG. 2, the sheet bar 2 with the superstructures 1, 5 and 13 is in the insertion position of the weft thread 3. In this position, the pre-nozzle arrangement 8 is permanently located, as a result of which the thread guide channels 5b 'and 8b' are opposite one another in alignment.
Such an arrangement has the advantage, inter alia, that deflections of the weft threads at the outlet of the blowpipes 8b and at the inlet of the main nozzles 5a are excluded at the time of the weft thread insertion and that, as already mentioned above, due to an identical ordering system between the main and pre-nozzles and the combination of all pre-nozzles in one pre-nozzle block, the effort for aligning the pre-nozzles on the main nozzles is minimized.
