Description

Die Erfindung betrifft ein Eintragsystem für eine Webmaschine mit wenigstens zwei Düsen, die in einem gemeinsamen Halter angeordnet sind und die jeweils einen Eingang für einen Schußfaden aufweisen und denen jeweils ein Zuführanschluß für ein Druckmedium zugeordnet ist. Ein solches Eintragsystem ist aus US-A-4 644 980 bekannt.The invention relates to an entry system for a weaving machine with at least two nozzles in a common holder are arranged and each have an input for one Have weft and each have a feed connection for a print medium is assigned. Such an entry system is known from US-A-4 644 980.

Bei Eintragsystemen der eingangs genannten Art sind die Zuführanschlüsse für das Druckmedium jeweils in der Nähe eines Injektor Abschnittes auf unterschiedlichen Seiten des Halters angeordnet. Abhängig von der Anzahl der Düsen sind die Zuführanschlüsse auf der Oberseite, auf der Unterseite oder auch an einer Seitenfläche des Halters angebracht. Daraus resultiert, daß Zuführleitungen, die an die Zuführanschlüsse angeschlossen werden, einander kreuzen müssen. Da das Eintragsystem mit den Düsen auf der Weblade angeordnet ist und sich mit dieser mitbewegt, kann dies dazu führen, daß die Zuführleitungen, die die Zuführanschlüsse mit stationären Versorgungseinrichtungen verbinden, aneinander anliegen und aneinander scheuern. Dieses Scheuern kann zu Beschädigungen der Zuführleitungen führen, wodurch Leckagen entstehen.In the case of entry systems of the type mentioned at the beginning, the feed connections are for the print medium close to each Injector section on different sides of the holder arranged. The supply connections are dependent on the number of nozzles on the top, on the bottom or also attached to a side surface of the holder. This results, that feed lines connected to the feed ports connected, must cross each other. Because the entry system is arranged with the nozzles on the sley and moving with it, this can lead to the supply lines, the supply connections with stationary utilities connect, rest against each other and against each other scrub. This rubbing can damage the Lead supply lines, causing leaks.

Der Erfindung liegt die Aufgabe zugrunde, ein Eintragsystem der eingangs genannten Art so auszubilden, daß die Zuführleitungen so angeordnet werden können, daß sie sich möglichst nicht berühren und möglichst nicht aneinander scheuern.The invention has for its object an entry system of the type mentioned in such a way that the feed lines can be arranged so that they are as possible do not touch and if possible do not rub against each other.

Diese Aufgabe wird dadurch gelöst, daß die Zuführanschlüsse für das Druckmedium auf der gleichen Seite des Halters in Längsrichtung der Düsen in Abstand zueinander angeordnet sind, und daß in dem Halter Kanäle vorgesehen sind, die jeweils von einem Zuführanschluß zu einer Düse führen.This object is achieved in that the feed connections for the print medium on the same side of the holder in The longitudinal direction of the nozzles is spaced apart are, and that channels are provided in the holder, each lead from a feed connection to a nozzle.

Die Erfindung bietet den Vorteil, daß die zu den Zuführanschlüssen führenden Zuführleitungen für das Druckmedium nach einem System verlegt werden können, das die Gefahr wesentlich verringert, daß die Zuführleitungen aneinander anliegen und miteinander reiben. Darüber hinaus kann das gesamte Eintragsystem kompakt ausgebildet werden. Die Erfindung ist vor allem dann von erheblichem Vorteil, wenn eine Mehrzahl von Düsen vorgesehen wird.The invention offers the advantage that the to the supply connections leading supply lines for the pressure medium a system can be installed that significantly increases the risk reduces that the feed lines abut each other and rub together. In addition, the entire entry system be compact. The invention is above all then of considerable advantage if a plurality of nozzles is provided.

Bevorzugt wird vorgesehen, daß die Zuführanschlüsse in einer Ebene angeordnet sind, in der die Längsachsen der zugehörigen Düsen liegen. Aufgrund dieser Anordnung kann der Halter relativ schmal ausgeführt werden, was den Vorteil hat, daß mehrere Düsen kompakt in einem Halter angeordnet werden können, oder daß mehrere Halter dicht nebeneinander auf der Weblade einer Webmaschine montiert werden können.It is preferably provided that the feed connections in a Plane are arranged in which the longitudinal axes of the associated There are nozzles. Because of this arrangement, the holder can be relative run narrow, which has the advantage that several Nozzles can be arranged compactly in a holder, or that several holders close together on the sley can be mounted on a weaving machine.

In Ausgestaltung der Erfindung wird vorgesehen, daß der Halter mit in Schußrichtung verlaufenden Aussparungen versehen ist, in die die Düsen eingesetzt sind, die zwischen einem Einführungselement für einen Schußfaden und einem Führungsrohr ein einen Injektor enthaltenden Abschnitt aufweisen, der zu dem Einführungselement und zu dem Führungsrohr oder zu einem nachfolgenden Führungselement in Längsrichtung der Aussparung abgedichtet ist und der an einen Zuführanschluß mittels eines Kanals angeschlossen ist. Dabei wird weiter bevorzugt vorgesehen, daß der von einem Zuführanschluß zu einer weiter entfernt angeordneten Düse führende Kanal die näher angeordnete Düse oder Düsen in einem Abschnitt umgibt, der in Längsrichtung der Düsen abgedichtet ist. Auf diese Weise wird erreicht, daß die Kanäle quer zu der Ebene der Längsachsen der Düsen keinen allzu großen Raum beanspruchen.In an embodiment of the invention it is provided that the holder provided with recesses running in the weft direction in which the nozzles are inserted, which are between one Insertion element for a weft thread and a guide tube have a portion containing an injector which to the insertion element and to the guide tube or to one following guide element in the longitudinal direction of the recess is sealed and by means of a feed connection a channel is connected. It is further preferred provided that the from a feed port to a more distant nozzle leading channel closer arranged nozzle or nozzles in a section that in Longitudinal direction of the nozzles is sealed. That way achieved that the channels transverse to the plane of the longitudinal axes the nozzles do not take up too much space.

Bei einer ersten Ausführungsform ist ein Halter mit mehreren Sätzen von Düsen versehen, die übereinander oder nebeneinander in zueinander im wesentlichen parallelen Ebenen angeordnet sind. Damit läßt sich ein sehr kompaktes Eintragsystem schaffen, bei welchem die Zuführanschlüsse für alle Düsen auf der gleichen Seite in systematischer Weise angebracht sind.In a first embodiment, there is one holder with several Sets of nozzles provided, one on top of the other or side by side arranged in mutually parallel planes are. This allows a very compact entry system create, in which the supply connections for all nozzles systematically attached to the same side.

Bei einer anderen Ausführungsform wird vorgesehen, daß ein Halter mit zwei oder mehr übereinander in einer gemeinsamen im wesentlichen vertikalen Ebene angeordneten Düsen versehen ist. Ein derartiger Halter baut relativ schmal. Dadurch kann in vorteilhafter weiterer Ausgestaltung vorgesehen werden, daß mehrere Halter mit jeweils wenigstens zwei Düsen nebeneinander angeordnet sind, und daß die Zuführanschlüsse auf der Oberseite der Halter angeordnet sind. Auf diese Weise wird ebenfalls ein sehr kompaktes Eintragsystem geschaffen, das in Modulbauweise mit mehreren Haltern und entsprechend einer Mehrzahl von Düsen ausgerüstet sein kann. Dabei wird zusätzlich vorzugsweise vorgesehen, daß die Halter - in der Draufsicht gesehen - sich in Schußrichtung verjüngen und mit ihren Seitenflächen aneinanderliegen. Dadurch ist es möglich, eine Vielzahl von Düsen relativ genau zu einem Führungskanal, insbesondere Luftführungskanal in einem Webblatt, auszurichten.In another embodiment it is provided that a Holders with two or more one above the other in a common provided in the substantially vertical plane arranged nozzles is. Such a holder is relatively narrow. This can can be provided in an advantageous further embodiment, that several holders with at least two nozzles each side by side are arranged, and that the feed connections on the top of the holder are arranged. In this way a very compact entry system is also created, the modular design with several brackets and so on can be equipped with a plurality of nozzles. Doing so additionally preferably provided that the holder - in the Seen from above - taper in the direction of the shot and with their side faces lie against each other. This makes it possible a large number of nozzles relative to a guide channel, in particular to align the air duct in a reed.

Jeder Halter 8 hält zwei Düsen 10, 11, die sich somit mit der Weblade 2 bewegen. Bei Luftdüsenwebmaschinen werden die Düsen 10, 11 Hauptdüsen genannt. Die den Haltern 8 abgewandten Enden der Düsen 10, 11 sind mit einer Halterung 12 an der Grundplatte angebracht.The entry system contains several holders 8, in the embodiment four holders 8, each by means of screws 9 are attached to a base plate, which in turn on the Sley 2 is attached. Each holder 8 holds two nozzles 10, 11, which thus move with the sley 2. For air jet weaving machines the nozzles 10, 11 are called main nozzles. The The ends of the nozzles 10, 11 facing away from the holders 8 are provided with a Bracket 12 attached to the base plate.

An der Oberseite 15 jedes der Halter 8 sind zwei Anschlußelemente 16, 17 vorgesehen, mittels welchen jeweils eine Düse 10, 11 mit Druckluft versorgt wird. An die Anschlußelemente 16, 17 sind Zuführleitungen 18, 19 angeschlossen. Die Zuführleitungen 18, 19 verlaufen bei dem Ausführungsbeispiel im Bereich der Anschlußelemente 16, 17 im wesentlichen vertikal. Sie sind in einem Abstand voneinander und parallel zueinander angeordnet und über nicht dargestellte Ventile an eine ebenfalls nicht dargestellte Druckluftversorgung angeschlossen. Gemäß einer nicht dargestellten Abwandlung können die Anschlußelemente 16, 17 auch in die Halter 8 integriert sein.On the top 15 of each of the holders 8 are two connection elements 16, 17 provided, by means of which a nozzle 10, 11 is supplied with compressed air. On the connection elements 16, 17 supply lines 18, 19 are connected. The feed lines 18, 19 run in the embodiment in the area the connecting elements 16, 17 substantially vertically. They are spaced apart and parallel to each other arranged and also via valves, not shown Compressed air supply, not shown, connected. According to a modification, not shown, the connection elements 16, 17 can also be integrated into the holder 8.

In Fig. 2 bis 5 sind jeweils Schnitte durch einen Halter 8 dargestellt, der zwei übereinander angeordnete Düsen 10, 11 enthält. Die Düsen 10, 11 sind untereinander gleich. Der Halter 8 ist mit einem Zuführanschluß 20, 21 für jede Düse 10, 11 versehen. Jede Düse 10, 11 besitzt ein Fadeneinführungselement 28, das einen Eingang 22 für einen nicht dargestellten Schußfaden aufweist. An das Einführungselement 28 schließt ein Führungselement 29 an, das mit dem Einführungselement 28 einen Injektor bildet. Auf das Führungselement 29 folgt ein Führungsrohr 24, das einen Ausgang 26 für die Druckluft und einen nicht dargestellten Schußfaden aufweist. Die Achsen des Einführungselementes 28 und des Führungselementes 29 verlaufen im wesentlichen koaxial zu den Achsen der Führungsrohre 24, so daß sie die Längsachsen 30, 31 der Düsen 10, 11 bilden. Ein Schußfaden läuft im wesentlichen entlang dieser Längsachsen 30, 31 durch die Düse 10, 11 hindurch, so daß die Längsachsen 30, 31 die Bewegungsrichtung A des Schußfadens bestimmen.2 through 5 are sections through a holder 8 shown, the two superposed nozzles 10, 11th contains. The nozzles 10, 11 are identical to one another. The keeper 8 is with a feed connection 20, 21 for each nozzle 10, 11 provided. Each nozzle 10, 11 has a thread insertion element 28, which has an input 22 for a not shown Has weft. To the insertion element 28 connects a guide element 29, which with the insertion element 28 forms an injector. On the guide element 29 follows a guide tube 24 which has an outlet 26 for the Compressed air and a weft thread, not shown. The axes of the insertion element 28 and the guide element 29 run essentially coaxially to the axes of the Guide tubes 24 so that they have the longitudinal axes 30, 31 of the nozzles 10, 11 form. A weft essentially runs along this longitudinal axes 30, 31 through the nozzle 10, 11, so that the longitudinal axes 30, 31 the direction of movement A of the weft determine.

Die Außenseite 32 des Einführungselementes 28 ist mit radialen Vorsprüngen 33 versehen. Das Führungselement 29 übergreift mit einer Innenfläche 34 die Außenseite 32 des Einführungselementes 28 im Bereich der Vorsprünge 33, so daß das Druckmedium zwischen der Außenseite 32 des Einführungselementes 28 und der Innenfläche 34 in das Führungselement 29 eingeführt wird. Die Innenfläche 34 liegt an den Vorsprüngen 33 an, so daß das Führungselement 29 in axialer Verlängerung zu dem Einführungselement 28 ausgerichtet ist. Das Einführungselement 28 und das Führungselement 29 bilden einen Injektor, durch welchen ein Schußfaden von dem Eingang 22 durch die Bohrung 35 des Einführungselementes 28, durch eine Bohrung 36 des Führungselementes 29 und durch das Führungsrohr 24 geführt wird. Das Einführungselement 28 und das Führungselement 29 sind mittels Schrauben 37 an dem Halter 8 gegen axiales Verschieben gesichert.The outside 32 of the insertion element 28 is radial Provide projections 33. The guide element 29 engages with an inner surface 34, the outer side 32 of the insertion element 28 in the region of the projections 33, so that the Print medium between the outside 32 of the insertion element 28 and the inner surface 34 are inserted into the guide element 29 becomes. The inner surface 34 lies on the projections 33 on, so that the guide element 29 in an axial extension the insertion element 28 is aligned. The introductory element 28 and the guide element 29 form an injector, through which a weft thread from the entrance 22 through the Bore 35 of the insertion element 28, through a bore 36 of the guide element 29 and guided by the guide tube 24 becomes. The insertion member 28 and the guide member 29 are by means of screws 37 on the holder 8 against axial Moved secured.

Die Zuführanschlüsse 20, 21 für die zwei übereinander angeordneten Düsen 10, 11 befinden sich an der gleichen Seite 15 des Halters 8 und zwar, wie dies in Fig. 1 bis 4 dargestellt ist, an der Oberseite 15 des Halters 8. Wie aus Fig. 3 und 4 zu ersehen ist, liegen die Zuführanschlüsse 20, 21 in einer Ebene 38, in der auch die Längsachsen 30, 31 der beiden Düsen 10, 11 liegen. Diese Ebene 38 ist eine Symmetrieebene des Halters 8. Wie Fig. 2 zeigt, sind die Zuführanschlüsse 20, 21 in Richtung der Längsachsen 30, 31 der Düsen 10, 11 in einem Abstand zueinander angeordnet.The feed connections 20, 21 for the two arranged one above the other Nozzles 10, 11 are located on the same side 15 of the holder 8, as shown in FIGS. 1 to 4 is on the top 15 of the holder 8. As shown in FIGS. 3 and 4 can be seen, the feed connections 20, 21 are in one Level 38, in which the longitudinal axes 30, 31 of the two nozzles 10, 11 lie. This plane 38 is a plane of symmetry of the Holder 8. As shown in FIG. 2, the feed connections 20, 21 in the direction of the longitudinal axes 30, 31 of the nozzles 10, 11 in one Spaced from each other.

Das Einführungselement 28 und das Führungselement 29 der beiden Düsen 10, 11 sind jeweils in eine axiale Aussparungen 42, 43 eingesetzt, in der sie mittels der Schrauben 37 gesichert sind. Der Zuführanschluß 20, der der Düse 10 zugeordnet ist, steht in direkter Verbindung mit einem Abschnitt der Düse, in welchem der Injektor beginnt. Dieser Abschnitt ist durch zwei Dichtungsringe 44, 45 nach außen abgedichtet. Der Außendurchmesser des Einführungselementes 28 ist in diesem Abschnitt so weit verringert, daß eine Ringkammer gebildet wird, von der das Druckmedium in das Führungselement 29 strömt. Der Zuführanschluß 21 für die Düse 11 ist über einen aus zwei Abschnitten 39, 40 bestehenden Kanal des Halters 8 mit dem Abschnitt der Düse 11 verbunden, in welchem sich der Injektor befindet. Wie aus Fig. 3 zu ersehen ist, umgibt der Abschnitt 40 des Kanals die Düse 10 im Bereich eines Abschnittes 41 des Führungselementes 29. Um ein Austreten des Druckmediums in diesem Bereich zu verhindern, ist ein weiterer Dichtungsring 45 vorgesehen, der diesen Kanalabschnitt 40 im Bereich des Führungselementes 29 nach außen abdichtet. Der Abschnitt 39 des Kanals setzt den zunächst im wesentlichen radial zu den Düsen 10, 11 verlaufenden Abschnitt 40 in axialer Richtung koaxial zur Düsenachse 31 fort, so daß das Druckmedium wieder zu dem Abschnitt der Düse 11 strömt, in welchem sich der Injektor befindet. Das Führungselement 29 der Düse 11 ist mittels eines weiteren Dichtungsringes 45 nach außen abgedichtet.The insertion element 28 and the guide element 29 of the two Nozzles 10, 11 are each in an axial recesses 42, 43 used, in which it is secured by means of the screws 37 are. The feed port 20 associated with the nozzle 10 is in direct communication with a section of the nozzle, in which the injector starts. This section is by two Sealing rings 44, 45 sealed to the outside. The outside diameter of the insertion element 28 is so in this section greatly reduced that an annular chamber is formed, from which the pressure medium flows into the guide element 29. The feed connector 21 for the nozzle 11 is over one of two sections 39, 40 existing channel of the holder 8 with the section connected to the nozzle 11, in which the injector is located. As can be seen from Fig. 3, section 40 of the Channel the nozzle 10 in the region of a portion 41 of the guide element 29. To escape the print medium in this To prevent the area, another sealing ring 45 provided that this channel section 40 in the region of the guide element 29 seals to the outside. Section 39 of the The channel initially sets it essentially radially to the nozzles 10, 11 extending section 40 in the axial direction coaxially to the nozzle axis 31 so that the pressure medium again to the Section of the nozzle 11 flows, in which the injector located. The guide element 29 of the nozzle 11 is by means of a another sealing ring 45 sealed to the outside.

Bei dem Ausführungsbeispiel nach Fig. 1 bis 5 besteht der Halter aus einem Gußteil, insbesondere aus einem Druckgußteil oder Spritzgußteil, in das die Abschnitte 39, 40 des Kanals eingeformt sind. Dabei können auch die Aussparungen 42, 43, sowie entsprechende Öffnungen für die Zuführanschlüsse 20, 21 eingeformt werden, die jedoch noch nachbearbeitet werden. In the embodiment of FIGS. 1 to 5 there is Holder from a cast part, in particular from a die-cast part or injection molded part into which the sections 39, 40 of the channel are molded. The cutouts 42, 43, and corresponding openings for the feed connections 20, 21 are molded in, but are still being reworked.

Wie in Fig. 6 dargestellt ist, kann der Halter 8 aber auch als ein Block hergestellt werden, in welchem nachträglich Bohrungen angebracht werden. Um dabei einen ausreichend großen Querschnitt für die Abschnitte 39, 40 des Kanals zu erhalten, müssen relativ große Bohrungen 46, 47 vorgesehen werden. In den Zuführanschluß 21, der gleichzeitig mit einer den Abschnitt 40 des Kanals bildenden Bohrung geschaffen wird, muß dann nachträglich ein den eigentlichen Anschluß bildendes Teil angesetzt werden. Das Führungselement 29 der Düse 11 ist mit einer Verdickung 48 versehen, deren Außendurchmesser der Bohrung 46 entspricht, mit welcher der Kanalabschnitt 39 geschaffen worden ist. Im Bereich dieser Verdickung 48 ist dann ein Dichtungsring 49 vorgesehen. Das Ausführungsbeispiel nach Fig. 6 unterscheidet sich im übrigen dadurch noch von dem Ausführungsbeispiel nach Fig. 1 bis 5, daß die Führungsrohre 24, 25 jeweils einteilig mit den Führungselementen 29 ausgebildet sind. Die Düsen 10, 11 des Ausführungsbeispieles nach Fig. 6 haben zwar etwas unterschiedliche Außenformen, jedoch entsprechen sie bezüglich ihrer Innenform einander völlig.As shown in Fig. 6, the holder 8 can also be produced as a block, in which subsequently Holes are made. To make it big enough To obtain a cross section for the sections 39, 40 of the channel, relatively large holes 46, 47 must be provided. In the feed port 21, the one with the Section 40 of the channel forming bore is created must then subsequently form the actual connection Part. The guide element 29 of the nozzle 11 is provided with a thickening 48, the outer diameter of which Bore 46 corresponds with which the channel section 39 is created has been. Then in the area of this thickening 48 a sealing ring 49 is provided. The embodiment according to Fig. 6 also differs from that Embodiment of FIGS. 1 to 5 that the guide tubes 24, 25 each formed in one piece with the guide elements 29 are. The nozzles 10, 11 of the embodiment 6 have somewhat different external shapes, however they correspond completely to each other in terms of their inner shape.

Bei dem Ausführungsbeispiel nach Fig. 7 und 8 sind drei Düsen 10, 11, 50 in einer gemeinsamen Ebene 53 übereinander angeordnet, so daß drei Zuführanschlüsse 20, 21, 52 vorgesehen werden. Die Zuführanschlüsse 20 und 21 stehen mit den zugehörigen Düsen 10, 11 in gleicher Weise in Verbindung, wie dies für das Ausführungsbeispiel nach Fig. 1 bis 5 erläutert wurde. Es sind die gleichen Bezugszeichen verwendet worden, so daß auf die betreffende Beschreibung verwiesen werden kann. Die unterste Düse 50 ist mit dem Zuführanschluß 52 mittels eines Führungskanals des Halters 8 verbunden, der aus einem zur Düse 50 koaxialen Abschnitt 39 und aus einem dazu lotrecht verlaufenden Abschnitt 51 besteht.7 and 8 are three nozzles 10, 11, 50 arranged one above the other in a common plane 53, so that three feed ports 20, 21, 52 are provided become. The feed connections 20 and 21 are with the associated Nozzles 10, 11 connected in the same way as this for the embodiment of FIGS. 1 to 5 has been explained. The same reference numerals have been used, see above that reference can be made to the description in question. The lowermost nozzle 50 is connected to the supply connection 52 a guide channel of the holder 8, which consists of a to the nozzle 50 coaxial section 39 and perpendicular to it extending section 51.

Wie insbesondere aus Fig. 8 zu ersehen ist, umgibt der Abschnitt 51 die Düsen 10 und 11 im Bereich des jeweiligen Führungselementes 29, wobei in diesem Bereich ein Abschnitt 41 des Führungselementes 29 nach außen mittels Dichtungsringen 44, 65 abgedichtet ist. Die Achse 54 der Düse 50 liegt in einer Ebene, in der auch die Achsen 30, 31 der Düsen 10, 11 liegen und in der auch die Zuführanschlüsse 20, 21, 52 angeordnet sind.As can be seen in particular from FIG. 8, the section surrounds 51 the nozzles 10 and 11 in the area of the respective guide element 29, a section 41 in this area of the guide element 29 to the outside by means of sealing rings 44, 65 is sealed. The axis 54 of the nozzle 50 lies in one Plane in which the axes 30, 31 of the nozzles 10, 11 lie and in which the feed connections 20, 21, 52 are also arranged are.

Wenn mehr als drei Düsen 10, 11, 50 in einem Halter 8 angeordnet werden, so läßt sich dies mit dem gleichen System realisieren, wie es anhand von Fig. 7 erläutert worden ist. Der jeweils der untersten Düse zugeordnete Zuführanschluß ist über einen Kanal mit der untersten Düse verbunden, der einen zu der Längsachse dieser Düse lotrechten Abschnitt aufweist, der alle darüber befindlichen Düsen umgibt und entsprechend mit Dichtungsringen im Bereich der jeweiligen Düsen abgedichtet ist.If more than three nozzles 10, 11, 50 are arranged in a holder 8 can be realized with the same system, as has been explained with reference to FIG. 7. The is the supply nozzle assigned to the lowest nozzle connected to the lowest nozzle via a channel, the one has a section perpendicular to the longitudinal axis of this nozzle, which surrounds all the nozzles above and accordingly sealed with sealing rings in the area of the respective nozzles is.

Bei der Ausführungsform nach Fig. 9 sind die Längsachsen 30, 31 der übereinander angeordneten Düsen 10, 11 in einer Ebene 38 angeordnet, die einen Winkel zur Vertikalen bildet. Dies erlaubt eine andere Anordnung der zugehörigen Führungsrohre 24. Der Zuführanschluß 21 befindet sich in der Mitte des Halters 8, so daß er etwas seitlich versetzt zu den Düsen 10 und 11 angeordnet ist. Der nicht sichtbare Zuführanschluß 20 wird dagegen lotrecht über der Längsachse 30 der Düse 10 angeordnet, d.h. etwas außermittig bezüglich der Oberseite 15 des Halters 8. Die Zuführanschlüsse 20, 21 sind ebenfalls in Längsrichtung der Längsachsen 30, 31 in einem Abstand zueinander angeordnet.In the embodiment according to FIG. 9, the longitudinal axes 30, 31 of the nozzles 10, 11 arranged one above the other in one plane 38 arranged which forms an angle to the vertical. This allows a different arrangement of the associated guide tubes 24. The feed port 21 is in the middle of the holder 8, so that it is offset somewhat laterally to the nozzles 10 and 11 is arranged. The invisible feed port 20 is on the other hand, arranged vertically above the longitudinal axis 30 of the nozzle 10, i.e. somewhat off-center with respect to the top 15 of the Holder 8. The feed ports 20, 21 are also in Longitudinal direction of the longitudinal axes 30, 31 at a distance from one another arranged.

Wie in Fig. 1 und 5 dargestellt ist, können mehrere Halter 8 mit jeweils zwei Düsen 10, 11 unmittelbar nebeneinander angeordnet werden. Zweckmäßig wird dabei vorgesehen, daß die Halter 8 sich in Schußrichtung verjüngen, d.h. die von der im Bereich des Eingangs 22 für Schußfäden befindlichen Stirnseite 60 ausgehenden Seitenwände 58, 59 konvergieren in Richtung zu dem Führungsrohr 24. Dadurch können die Führungsrohre 24 der Düsen 10, 11 zu dem Führungskanal 4 des Webblattes ausgerichtet werden. Die Halter 8 mit jeweils zwei oder mehr Düsen erlauben eine modulare Bauweise eines Eintragsystems, das an die gewünschten Betriebsbedingungen angepaßt werden kann.As shown in FIGS. 1 and 5, a plurality of holders 8 with two nozzles 10, 11 arranged directly next to each other become. It is conveniently provided that the holder 8 taper in the weft direction, i.e. that of the im Area of the entrance 22 for weft threads end face 60 outgoing side walls 58, 59 converge in the direction to the guide tube 24. As a result, the guide tubes 24 of the nozzles 10, 11 aligned with the guide channel 4 of the reed become. The holder 8, each with two or more nozzles allow a modular design of an entry system that the desired operating conditions can be adapted.

Es reicht aus, wenn nur ein Halter 8 mit zwei Düsen 10, 11 vorgesehen ist. Bevorzugt werden jedoch entsprechend der Darstellung nach Fig. 1 mehrere Halter 8 mit mindestens zwei Düsen 10, 11 nebeneinander angeordnet, beispielsweise zwei, drei, vier oder auch mehr, so daß mit vier, sechs, acht oder mehr Düsen gewoben werden kann. Die Zuführanschlüsse 20, 21 aller Halter 8 befinden sich dabei auf der gleichen Seite der Halter 8, d.h. bei dem Ausführungsbeispiel nach Fig. 1 auf der Oberseite 15 jedes Halters 8. Selbstverständlich ist es auch möglich, die Halter 8 nicht nebeneinander anzuordnen, sondern beispielsweise nach einer Verdrehung um 90° übereinander. In diesem Fall würden sich die Anschlußelemente 16, 17 und die Zuleitungen 18, 19 dann auf einer Seitenfläche der Halter 8 befinden.It is sufficient if only one holder 8 with two nozzles 10, 11 is provided. However, according to the illustration, are preferred 1 several holders 8 with at least two nozzles 10, 11 arranged side by side, for example two, three, four or more, so that with four, six, eight or more nozzles can be woven. The feed ports 20, 21 all holder 8 are on the same side of the Holder 8, i.e. in the embodiment of FIG. 1 the top 15 of each holder 8. Of course it is also possible not to arrange the holders 8 next to one another, but, for example, after being rotated 90 ° one above the other. In this case, the connection elements 16, 17 and the leads 18, 19 then on a side surface of the Holder 8 are.

Selbstverständlich ist es auch möglich, mehrere Sätze von zwei übereinander angeordneten Düsen 10, 11 oder drei übereinander angeordneten Düsen 10, 11, 50 in einem einstückigen Halter 8 unterzubringen, der dann mit den Kanälen entsprechend den Ausführungsbeispielen nach Fig. 2 bis 9 versehen wird. Auch in diesem Fall befinden sich dann alle Zuführanschlüsse 20, 21, 52 der übereinander angeordneten Düsen 10, 11, 50 auf der gleichen Seite des Halters 8, wobei die Zuführanschlüsse 20, 21, 52 eines Satzes von Düsen 10, 11, 50 jeweils in Längsrichtung der Längsachsen 30, 31, 54, der Düsen 10, 11, 50 in Abstand zueinander sowie vorzugsweise auch in den Ebenen 38, 53 der Längsachsen 30, 31, 54 angeordnet sind. Die Ebenen 38, 53 der verschiedenen Sätze von Düsen 10, 11, 50 verlaufen dann im wesentlichen parallel zueinander.Of course, it is also possible to have multiple sets of two nozzles 10, 11 or three arranged one above the other arranged nozzles 10, 11, 50 in one piece To accommodate holder 8, which then with the channels accordingly the embodiments of FIGS. 2 to 9 provided becomes. In this case too, all feed connections are located 20, 21, 52 of the nozzles 10 arranged one above the other, 11, 50 on the same side of the holder 8, with the feed ports 20, 21, 52 of a set of nozzles 10, 11, 50 each in the longitudinal direction of the longitudinal axes 30, 31, 54, of the nozzles 10, 11, 50 at a distance from one another and preferably also arranged in the planes 38, 53 of the longitudinal axes 30, 31, 54 are. The planes 38, 53 of the different sets of nozzles 10, 11, 50 then run essentially parallel to one another.

In dem Ausführungsbeispiel nach Fig. 10 bis 12 sind beispielsweise zwei Sätze von jeweils zwei Düsen 10, 11 in einem gemeinsamen Halter 63 angeordnet. Der Halter 63 ist mit jeweils zwei Zuführanschlüssen 20 und 21 versehen, die sich auf der gleichen Fläche des Halters 63 befinden, bei dem Ausführungsbeispiel auf einer Seitenfläche 64. Jedem Satz der zwei Düsen 10, 11 ist jeweils an der Seitenfläche 64 ein Zuführanschluß 20 und ein Zuführanschluß 21 zugeordnet, die in Richtung der Längsachsen 30, 31 der Düsen 10, 11 in einem Abstand zueinander angeordnet sind. Pro Satz von Düsen 10, 11 ist jeweils in dem Halter 63 ein Führungskanal mit Abschnitten 39, 40 vorgesehen, um das Druckmedium von dem zugehörigen Zuführanschluß 21 zu der Düse 11 zu leiten. Die Düsen 10, 11 liegen bei dieser Ausführungsform jeweils in einer Ebene 38 nebeneinander, die durch die Längsachsen 30, 31 der Düsen verläuft. In diesen Ebenen liegen auch die zugehörigen Zuführanschlüsse 20, 21.10 to 12 are for example two sets of two nozzles 10, 11 in one common holder 63 arranged. The holder 63 is with each provided two feed ports 20 and 21, which are on the same area of the holder 63, in the embodiment on a side surface 64. Each set of the two Nozzles 10, 11 is a feed port on each side surface 64 20 and a feed port 21 assigned in the direction the longitudinal axes 30, 31 of the nozzles 10, 11 at a distance are arranged to each other. Per set of nozzles 10, 11 is each in the holder 63 a guide channel with sections 39, 40 provided to the print medium from the associated supply port 21 to lead to the nozzle 11. The nozzles 10, 11 are located in this embodiment in each case in a plane 38 side by side, which runs through the longitudinal axes 30, 31 of the nozzles. The associated feed connections are also located on these levels 20, 21.

Wie in Fig. 11 dargestellt ist, besitzen die Düsen 10, 11 alle die gleiche Innenform. Das Einführungselement 28 für den Schußfaden der Düsen 11 unterscheidet sich jedoch von dem Einführungselement 28 der Düsen 10 durch einen im Durchmesser vergrößerten Anfangsteil. Dieser Anfangsteil hat einen Außendurchmesser, der dem Innendurchmesser der Bohrung 65 entspricht, mit welchem der Abschnitt 39 des Kanals beschaffen worden ist, der von dem Zuführanschluß 21 zu der Düse 11 führt.As shown in Fig. 11, the nozzles 10, 11 all have the same inner shape. The insertion element 28 for the However, the weft thread of the nozzles 11 differs from that Insertion element 28 of the nozzles 10 by one in diameter enlarged initial part. This initial part has an outer diameter, which corresponds to the inside diameter of the bore 65, with which the section 39 of the channel procured which is from the supply port 21 to the nozzle 11 leads.

In Fig. 13 ist ein Ausführungsbeispiel dargestellt, das im Prinzip dem Ausführungsbeispiel nach Fig. 6 entspricht. Um den Abschnitt 40 des Kanals mit einem kleineren Durchmesser bohren zu können und dennoch einen genügend großen Querschnitt zu erhalten, ist das Führungselement 28 der Düse 10 im Bereich der Bohrung 47 mit einer Ringnut versehen. Derartige Ringnuten 61 können auch bei anderen Ausführungsbeispielen vorgesehen werden, beispielsweise bei dem Ausführungsbeispiel nach Fig. 8. In diesem Fall würden insbesondere im Bereich des Abschnittes 51 des Kanals die Führungselemente 29 der Düsen 10 und 11 mit entsprechenden Ringnuten 61 versehen werden. In Fig. 13 an embodiment is shown, which in Principle corresponds to the embodiment of FIG. 6. Around the section 40 of the channel with a smaller diameter to be able to drill and still have a sufficiently large cross-section to obtain the guide element 28 of the nozzle 10 Provide an annular groove in the area of the bore 47. such Ring grooves 61 can also be used in other exemplary embodiments can be provided, for example in the embodiment according to Fig. 8. In this case, especially in the area of section 51 of the channel, the guide elements 29 the nozzles 10 and 11 are provided with corresponding annular grooves 61 become.

Wie in Fig. 14 dargestellt ist, ist es selbstverständlich auch möglich, die Zuführanschlüsse 20 und 21 zu vertauschen, d.h. den Zuführanschluß 21 für die untere Düse 11 in dem den Eingängen 22 des Einführungselementes 28 näherliegenden Bereich und die Zuführanschlüsse 20 für die Düse 10 in dem diesen Eingängen 22 abgewandten Bereich anzuordnen. In diesem Fall wird der unteren Düse 11 ein entsprechend geformter Kanal 66 in dem Halter 8 zugeordnet. In entsprechender Weise können natürlich auch drei oder mehr Düsen übereinander angeordnet und mit Druckmedium versorgt werden. Selbstverständlich sind auch Kombinationen zwischen den Ausführungsformen nach Fig. 2, 6, 7, 11, 13 und 14 möglich.As shown in Fig. 14, it goes without saying also possible to interchange the feed connections 20 and 21, i.e. the feed port 21 for the lower nozzle 11 in the Inputs 22 of the insertion member 28 closer area and the feed ports 20 for the nozzle 10 therein Arrange entrances 22 facing away. In this In this case, the lower nozzle 11 becomes a correspondingly shaped channel 66 assigned in the holder 8. In a similar way Of course, three or more nozzles can also be arranged one above the other and be supplied with pressure medium. Of course are also combinations between the embodiments 2, 6, 7, 11, 13 and 14 possible.

Bei einer nicht dargestellten Ausführungsform ist ein einzelner Halter für acht Düsen vorgesehen, deren Führungsrohre entsprechend der Darstellung nach Fig. 1 angeordnet werden. Wenn die Zuführanschlüsse auf der Oberseite eines derartigen Halters vorgesehen werden, sind vier Sätze von jeweils zwei übereinander angeordneten Düsen vorgesehen. Wenn die Zuführanschlüsse an der Seite dieses Halters angebracht sind, können beispielsweise zwei Sätze von jeweils vier nebeneinander angeordneten Düsen vorgesehen werden. Pro Düsensatz sind die zugehörigen Zuführanschlüsse entsprechend den Ausführungsformen nach Fig. 1 bis 14 in Richtung der Längsachsen der Düsen der Düsensätze in Abstand zueinander angeordnet. Pro Düsensatz sind ein oder drei Kanäle für die Zuführung des Druckmediums vorgesehen, die von dem betreffenden Zuführanschluß zu den Düsen führen.In one embodiment, not shown, is a single one Holder provided for eight nozzles, their guide tubes be arranged according to the representation of FIG. 1.
