Description

Die Erfindung betrifft eine Vorrichtung zum Strecken und Spannen eines Schussfadens für eine Düsenwebmaschine gemäss dem Oberbegriff des Anspruches 1 und eine Webmaschine mit einer solchen Vorrichtung.The invention relates to a device for stretching and tensioning a weft thread for a jet loom according to the preamble of claim 1 and a loom with such a device.

In der DE-A-32 00 637 ist eine Düsenwebmaschine mit einem Schussfadenwächter und mit einer Spannvorrichtung zum Strecken und Gespannthalten eines Schussfadens bis zum Anschlag beschrieben. Diese Vorrichtung weist einen Körper mit einer halboffenen Ausnehmung auf, deren eine Begrenzungsfläche eine Lufteintrittsöffnung und deren andere Begrenzungsfläche eine Luftaustrittsöffnung aufweist. Die beiden Öffnungen liegen einander gegenüber und sind an einer Luftzuführleitung bzw. an einer Luftabsaugleitung angeschlossen, so dass in der Ausnehmung quer zur Schussrichtung ein Luftstrom erzeugt werden kann. Durch diesen Luftstrom wird der Endabschnitt eines einzutragenen Schussfadens nach dem Durchflug des Fadenwächters erfasst und in die Luftabsaugleltung ausgelenkt.In DE-A-32 00 637 a jet loom with a weft detector and with a tensioning device for stretching and holding a weft yarn to a stop is described. This device has a body with a half-open recess, whose one boundary surface has an air inlet opening and whose other boundary surface has an air outlet opening. The two openings are opposite each other and are connected to an air supply line or to an air suction, so that in the recess transversely to the firing direction, an air flow can be generated. By this air flow, the end portion of a weft thread to be entered is detected after passing through the thread monitor and deflected into the Luftabsaugleltung.

Als nachteilig erweist sich bei diesen Vorrichtungen, dass lediglich ein gerichteter Luftstrahl zur Fadenablenkung vorgesehen ist.
Aus der JP-A-6-43/88 ist eine Vorrichtung bekannt, bei der eine Düse seitlich versetzbar ist, jedoch nur um einen Arbeitsort innerhalb des Webblattes zu wählen, jedoch nicht um den Düsenstrahl zu beeinflussen. Weiter ist die Düse in Schussrichtung verschwenkbar, um die Absaugung zu unterbrechen und den Schussfaden nicht in den Saugkanal abzulenken, sondern längs des Schusskanals abzuführen.A disadvantage proves in these devices that only a directed air jet is provided for thread deflection.
From JP-A-6-43 / 88, a device is known in which a nozzle is laterally displaceable, but only to select a place of work within the reed, but not to influence the jet. Further, the nozzle is pivotable in the weft direction to interrupt the suction and not to deflect the weft in the suction channel, but dissipate along the firing channel.

Der Erfindung liegt die Aufgabe eine Vorrichtung zum Strecken und Spannen eines Schussfadens zu verbessern.The object of the invention is to improve a device for stretching and tensioning a weft thread.

Diese Aufgabe wird erfindungsgemäss durch die Merkmale des Anspruches 1 gelöst.This object is achieved by the features of claim 1.

Die Erfindung hat die Vorteile, dass die Düse einerseits zwei Luftstrahlen erzeugt, welche einen Luftvorhang bilden und dass die Düse andererseits bezüglich dem Kanal einstellbar ist. Dadurch wird unabhängig von der Fadenart eine Fadenablenkung gewährleistet und der Schussfaden sicher gespannt gehalten.The invention has the advantages that the nozzle on the one hand generates two jets of air, which form an air curtain and that the nozzle on the other hand is adjustable with respect to the channel. As a result, a thread deflection is ensured regardless of the type of thread and held the weft safely stretched.

Nachfolgend wird die Erfindung anhand der beiliegenden Zeichnungen erläutert.The invention will be explained with reference to the accompanying drawings.

Auf der Fangseite einer Webmaschine sind in Schussrichtung einem Webblatt 1 mit einem Führungskanal 2 für einen Schussfaden, ein Schussfadenwächter 3 und eine Vorrichtung 4 der hier in Rede stehenden Art nachgeordnet.On the catching side of a loom, a reed 1 with a guide channel 2 for a weft thread, a weft thread guard 3 and a device 4 of the type in question are arranged downstream in the weft direction.

Es wird auf die Figuren 2 bis 4 Bezug genommen. Wie die Fig. 4 zeigt, enthält die Vorrichtung 4 einen Düsenhalter 5 und eine Düse 6, die am Düsenhalter montiert ist. Der Düsenhalter 5 hat eine Durchbohrung 8, die einen Kanal zur Aufnahme eines Schussfadens 9 bildet und einen Ansatz 10, der eine geschlitzte Bohrung zur Aufnahme der Düse 6 aufweist. Die Düse 6 besteht aus einen Körper 11, dereinen rechteckähnlichen Querschnitt mit parallelen Längsseiten und gerundeten Schmalseiten (Fig.2) und einen zylindrischen Ansatz 12 aufweist. In der Düse sind eine Blindbohrung 13 und zwei Düsenlöcher 14 ausgebildet, die parallel zueinander angeordnet und in der gerundeten Seite ausmünden. Die Düse ist im Halter drehbar montiert und durch eine nicht dargestellte Schraube gesichert. Dadurch wird eine halboffene Ausnehmung 15 gebildet, welche mit dem Führungskanal 2 fluchtet. Die Düse 6 ist mit einer Leitung 16 zum Zuführen von Luft verbunden.Reference is made to FIGS. 2 to 4. As shown in Fig. 4, the apparatus 4 includes a nozzle holder 5 and a nozzle 6 mounted on the nozzle holder. The nozzle holder 5 has a through hole 8 which forms a channel for receiving a weft thread 9 and a projection 10 which has a slotted hole for receiving the nozzle 6. The nozzle 6 consists of a body 11, which has a rectangular-like cross-section with parallel longitudinal sides and rounded narrow sides (Figure 2) and a cylindrical projection 12. In the nozzle, a blind bore 13 and two nozzle holes 14 are formed, which are arranged parallel to each other and open out in the rounded side. The nozzle is rotatably mounted in the holder and secured by a screw, not shown. As a result, a half-open recess 15 is formed, which is aligned with the guide channel 2. The nozzle 6 is connected to a conduit 16 for supplying air.

In der Fig.2 ist die Düse 6 in einer Stellung gezeigt, in welcher analog zum Stand der Technik die Düsenlöcher mit dem Kanal fluchten. Aufgrund der sich schneidenden Luftstrahlen treten die bekannten Probleme auf. Ist der Förderluftstrom für den Schussfaden stärker als Luftstrom aus der Düse 6, so wird der Schussfaden 9 nicht korrekt abgelenkt und gespannt. Ist der Luftstrom aus der Düse 6 stärker, so wird der Förderiuftstrom für den Schussfaden bereits vor Erreichen der Vorrichtung abgelenkt. Somit sind die sich schneidenden Luftstöme aufeinander abzustimmen, was sehr aufwendig ist. Bei der ersten Ausführungsform der Vorrichtung wird in vorteilhafter Weise diese Abstimmung der Luftströme durch Schwenken der Düse 6 und damit des erzeugten Luftvorhanges erleichtert ( Fig.3).2, the nozzle 6 is shown in a position in which, analogously to the prior art, the nozzle holes are aligned with the channel. Due to the cutting air jets occur the known problems. If the conveying air flow for the weft thread stronger than air flow from the nozzle 6, the weft thread 9 is not deflected correctly and tense. If the air flow from the nozzle 6 is stronger, the conveying air flow for the weft yarn is deflected even before reaching the device. Thus, the intersecting air currents are matched, which is very expensive. In the first embodiment of the device, this tuning of the air streams by pivoting the nozzle 6 and thus the generated air curtain is facilitated in an advantageous manner (Figure 3).

Die Figuren 5 bis 7 zeigen eine zweite Ausführungsform der Vorrichtung. Wie Fig.7 zeigt ist bei dieser Vorrichtung ein Düsenhalter 21 in einen Grundkörper 22 mit dem Kanal 8 und ein plattenförmiges Halteelement 23 für die Düse 6 unterteilt. Das Halteelement 23 ist mit der geschlitzten Bohrung versehen, in welcher die Düse 6 angeordnet ist und mittels einer Schraube 26 am Grundkörper zu befestigen. Wie die Fig. 7 zeigt, ist das Halteelement 23 so angeordnet, dass einerseits die halboffene Ausnehmung 15 gebildet wird und andererseits die Düsenmündungen der Düse 6 mit der Mündung des Kanals 8 fluchtet. In der Stellung gemäss Fig. 5 treten die vorstehend erläuterten Probleme auf, welche jedoch durch versetzen der Düse 6 gemäss Fig. 6 behoben werden. In der Fig. 6 ist die zweiten Ausführungform der Vorrichtung so angeordnet, dass einerseits die halboffene Ausnehmung gebildet wird und andererseits die Düsenmündungen der Düse 6 zur Mündung des Kanals 8 entgegen der Schussrichtung versetzt sind.FIGS. 5 to 7 show a second embodiment of the device. As FIG. 7 shows, in this device a nozzle holder 21 is subdivided into a base body 22 with the channel 8 and a plate-shaped holding element 23 for the nozzle 6. The holding element 23 is provided with the slotted bore, in which the nozzle 6 is arranged and fastened by means of a screw 26 on the base body. As shown in FIG. 7, the holding element 23 is arranged so that on the one hand the half-open recess 15 is formed and on the other hand, the nozzle orifices of the nozzle 6 is aligned with the mouth of the channel 8. In the position according to FIG. 5, the problems explained above occur, which, however, are remedied by displacing the nozzle 6 according to FIG. 6, the second embodiment of the device is arranged so that on the one hand, the half-open recess is formed and on the other hand, the nozzle orifices of the nozzle 6 are offset to the mouth of the channel 8 against the weft direction.

Wie bereits erwähnt sind, die Düsenlöcher 14 parallel zueinander angeordnet. Wird der Düse 6 Luft zugeführt, so wird mittels der Düsenlöcher 14 ein Luftvorhang erzeugt. Dieser Luftvorhang erstreckt sich quer zum Förderluftstrom für einen Schussfaden. Durch diesen Luftvorhang wird in erster Linie der Förderluftstrom für den Schussfaden und somit auch der Schussfaden zur Kanalmündung abgedrängt und in den Kanal B geleitet. Dadurch wird in vorteilhafter Weise der Schussfaden sowohl durch den Luftstrom aus der Düse als auch durch die Förderluftstrom für den Schussfaden gestreckt gehalten und gespannt. Die Vorrichtung weist einen Düsenhalter (5) mit einem Kanal (8) zur Aufnahme eines Schussfadens und eine Düse (6) mit Düsenlöchern (14) zum Strecken und Spannen des Schussfadens auf. Die Düse (6) ist am Düsenhalter montiert, derart, dass die Düse bezüglich der Schussrichtung einstellbar, insbesondere schwenkbar oder versetzbar ist. Mit dieser Vorrichtung wird in vorteilhafter Weise die optimale Einstellung der sich kreuzenden Luftstrahlen erleichtert und unabhängig von der Fadenart eine Ablenkung des Schussfadens (9) gewährleistet und der Schussfaden sicher gespannt gehalten.As already mentioned, the nozzle holes 14 are arranged parallel to one another. If the nozzle 6 supplied air, an air curtain is generated by means of the nozzle holes 14. This air curtain extends transversely to the conveying air flow for a weft thread. Through this air curtain, the conveying air flow for the weft thread and thus also the weft yarn is pushed to the channel mouth and directed into the channel B in the first place. As a result, the weft thread is advantageously kept stretched and stretched both by the airflow out of the nozzle and by the conveying air flow for the weft thread. The device has a nozzle holder (5) with a channel (8) for receiving a weft thread and a nozzle (6) with nozzle holes (14) for stretching and tensioning the weft thread. The nozzle (6) is mounted on the nozzle holder, such that the nozzle with respect to the weft direction is adjustable, in particular pivotable or displaceable. With this device, the optimum adjustment of the intersecting air jets is facilitated in an advantageous manner and regardless of the type of yarn ensures a deflection of the weft thread (9) and kept the weft safely stretched.
