Description

Die Erfindung bezieht sich auf ein Zahnelement zur Führung des Schusseintrags-Luftstrahles bei einer Düsenwebmaschine, mit einer Öffnung für den Durchtritt des Luftstrahles und einem Schlitz für den Austritt des eingetragenen Schusses beim folgenden Rietanschlag.The invention relates to a toothed element for guiding the weft insertion air jet in a jet weaving machine, with an opening for the passage of the air jet and a slot for the exit of the weft inserted during the following reed stop.

Bei einem bisherigen Zahnelement einer Luftdüsenwebmaschine (DE-OS 2739431) befindet sich in einem passenden Bereich des Umfanges der Luftstrahlöffnung ein radial gerichteter Schlitz für den Austritt des Schussfadens beim folgenden Rietanschlag. Das Zahnelement bzw. die Luftstrahlöffnung erstreckt sich somit nahezu über 360 und begrenzt überall die Luftstrahlöffnung durchgehend. Lediglich an dem einzigen Fadenaustrittsschlitz ist das Element unterbrochen.In a previous tooth element of an air jet weaving machine (DE-OS 2739431) there is a radially directed slot for the exit of the weft thread at the following reed stop in a suitable area of the circumference of the air jet opening. The tooth element or the air jet opening thus extends almost over 360 and continuously delimits the air jet opening everywhere. The element is interrupted only at the single thread exit slot.

Bei diesem bekannten Zahnelement neigt der Lufteintragsstrahl dazu, sich in Richtung zum Fadenaustrittsschlitz hin zu dezentralisieren. Dieser Effekt wiederholt sich bei den folgenden Zahnelementen entlang der Schusslinie sukzessive, so dass auch das einzutragende Schussmaterial (im folgenden ist beispielsweise ein Schussfaden angenommen) mehr und mehr aus der Mitte der Luftstrahlöffnung der einzelnen Zahnelemente und damit aus der Schusslinie abgelenkt werden kann. Die Fadenspitze kann dann schliesslich auf die Begrenzungswandung eines Zahnelementes auftreffen, wodruch der Schusseintrag gestört werden kann.In this known tooth element, the air inlet jet tends to decentralize in the direction of the thread exit slot. This effect is repeated in the following tooth elements along the weft line, so that the weft material to be inserted (in the following, for example, a weft thread is assumed) can be deflected more and more from the center of the air jet opening of the individual tooth elements and thus from the weft line. The thread tip can then finally hit the boundary wall of a tooth element, which can interfere with the weft insertion.

Der Erfindung liegt die Aufgabe zugrunde, ein besonders in dieser Hinsicht verbessertes Zahnelement zu schaffen.The invention has for its object to provide a particularly improved in this regard tooth element.

Die Erfindung liegt in einer zusätzlich zu dem Austrittsschlitz in der Luftstrahlöffnung angebrachten Ausnehmung, welche auf der durch Austrittsschlitz und Schusslinie verlaufenden Geraden dem Austrittsschlitz gegenüber angeordnet ist.The invention lies in a recess made in addition to the outlet slot in the air jet opening, which is arranged on the straight line running through the outlet slot and the firing line opposite the outlet slot.

Hierdurch lässt sich ein Druckausgleich auf der dem Fadenaustrittsschlitz gegenüberliegenden Seite der Luftstrahlöffnung des Zahnelementes erzielen, d.h. auch auf dieser Seite nimmt der Druck etwa in gleichem Mass ab wie auf der Seite des Fadenaustrittsschlitzes. Man erhält somit symmetrische Druckverhältnisse innerhalb der Luftstrahlöffnung jedes Zahnelementes. Damit lässt sich der Luftstrahl in sämtlichen Zahnelementen entlang der Schusslinie zentrieren, wodurch auch der Schussfaden ständig im Zentrum der einzelnen Zahnelemente gehalten werden kann. Die Spitze des einzutragenden Schussfadens kann somit ohne Dezentralisierung und ohne störendes Aufschlagen auf ein Zahnelement ganz in das Webfach eingetragen werden. Man erhält einen besonders störungsfreien Schusseintrag mittels des Luftstrahles.This allows pressure equalization to be achieved on the side of the air jet opening of the tooth element opposite the thread outlet slot, i.e. on this side, too, the pressure decreases to the same extent as on the side of the thread outlet slot. This gives symmetrical pressure conditions within the air jet opening of each tooth element. The air jet can thus be centered in all tooth elements along the weft line, as a result of which the weft thread can also be kept constantly in the center of the individual tooth elements. The tip of the weft thread to be entered can thus be completely inserted into the shed without decentralization and without disturbing knocking on a tooth element. A particularly trouble-free weft insertion is obtained by means of the air jet.

Es ist zwar auch ein Zahnelement einer Düsenwebmaschine bekannt (DE-OS 19 17 780), das zwei nebeneinander angeordnete Luftführungs- öffnungen enthält, die miteinander über einen Ausfädelschlitz verbunden sind. Dieser dient dazu, dass ein durch die hintere Öffnung eingetragener Schussfaden beim Rietanschlag in die vordere Öffnung übertreten und von hier aus dem Zahnelement austreten kann. Der zwischen beiden Öffnungen liegende Ausfädelschlitz ist jedoch nicht bezüglich der Schusslinie (Mittelachse) der vorderen Öffnung symmetrisch zu deren Ausfädelschlitz angeordnet, sondern in einem Bogenabstand von ca. 120° von ihm, also in asymmetrischer Anordnung. Aus diesem Grund kann dort keine Zentrierung des Schussfadens im obenerwähnten Sinn eintreten. Vielmehr wird dieser aufgrund der asymmetrsichen Schlitzanordnung einseitig in Richtung auf das Riet hin abgelenkt.A tooth element of a jet weaving machine is also known (DE-OS 19 17 780), which contains two air guide openings arranged next to one another, which are connected to one another via a threading slot. This serves to ensure that a weft thread inserted through the rear opening can pass into the front opening at the reed stop and can exit the tooth element from here. However, the threading slot lying between the two openings is not arranged symmetrically with respect to the firing line (central axis) of the front opening, but at an arc distance of approximately 120 ° from it, that is to say in an asymmetrical arrangement. For this reason, there can be no centering of the weft thread in the sense mentioned above. Rather, this is deflected on one side towards the reed due to the asymmetrical slot arrangement.

Further features of the invention result from the following description of exemplary embodiments in conjunction with the claims and the drawing.
  • 1 shows a tooth element of a weaving machine with an air jet entry designed according to the invention,
  • 2 is an associated section,
  • 3 is a front view of a modified embodiment;
  • 4 is an associated section,
  • 5 and 6, FIGS. 7 and 8 and FIGS. 9 and 10 illustrate further designs in corresponding representations,
  • FIG. 11 shows the variant according to FIG. 1 in use with a weaving machine and
  • 12 shows an associated section through the most important parts of the weaving machine along the weft line.

Das Zahnelement 1 enthält eine Öffnung 2 für den Durchtritt des Luftstrahles. Öffnung 2 ist mit einer Schräge 20 versehen und hat im wesentlichen kreisrunde Innenbegrenzung 3. Ein radial gerichteter Schlitz 4 dient zum Austritt eines durch die Öffnung 2 vertikal zu Fig. 1 eingetragenen Schussfadens 28 (Schusslinie 6) während des auf den Eintrag folgenden Rietanschlages.The tooth element 1 contains an opening 2 for the passage of the air jet. Opening 2 is provided with a bevel 20 and has an essentially circular inner boundary 3. A radially directed slot 4 serves for the exit of a weft thread 28 (weft line 6) entered through opening 2 vertically to FIG. 1 during the reed stop following the entry.

Diametral gegenüber dem Fadenaustrittsschlitz 4 ist ein Schlitz 5 angeordnet, der bei diesem Beispiel im vollen Material endet, also nicht wie der Austrittsschlitz 4 durchgehend ausgebildet ist. Durch den Blindschlitz 5 wird erreicht, dass der Druck des Luftstrahles von der Schusslinie 6 in Richtung der beiden Schlitze 4, gleichmässig abnimmt. Somit herrschen in der Öffnung 2 symmetrische Druckverhältnisse. Luftstrahl und Faden lassen sich dadurch leicht im Zentrum bzw. der Schusslinie 6 während des Eintrages halten.A slot 5 is arranged diametrically opposite the thread exit slot 4, which in this example ends in the full material, that is to say not in a continuous manner like the exit slot 4. The blind slit 5 ensures that the pressure of the air jet from the firing line 6 in the direction of the two slits 4 decreases uniformly. Thus there are 2 symmetrical pressure conditions in the opening. The air jet and thread can thus be easily held in the center or the line of fire 6 during the entry.

Bei dem Beispiel nach Fig. 3,4 enthält das Zahnelement 1 einen oberen, etwa halbkreisförmig ausgebildeten Teil 7, der mittels zweier Stifte 8 unter Innehaltung von Spiel 9 an dem unteren Teil 11 des Zahnelementes befestigt ist.In the example according to FIG. 3, 4, the toothed element 1 contains an upper, approximately semicircular part 7, which is fastened to the lower part 11 of the toothed element by means of two pins 8, while maintaining play 9.

Das Spiel 9 bildet in ähnlicher Weise wie der Schlitz 5 nach Fig. 1 und 2 einen Druckausgleich in der Öffnung 2 mit dem Unterschied, dass bei diesem Beispiel der durch das Spiel 9 gebildete Druckausgleichschlitz sich bis zum Ende des Zahnelementes bei 12 fortsetzt, also durchgehend ausgebildet ist.The game 9 forms a pressure equalization in the opening 2 in a similar manner to the slot 5 according to FIGS. 1 and 2, with the difference that in this example the pressure equalization slot formed by the game 9 extends until the end of the Tooth element continues at 12, that is, formed continuously.

Bei dem Beispiel nach Fig. 5, 6 ist die innere Begrenzung 3a der Luftstrahlöffnung 2 quadratisch ausgebildet. Im übrigen entspricht diese Variante weitgehend derjenigen nach Fig. 3, 4.5, 6, the inner boundary 3a of the air jet opening 2 is square. Otherwise, this variant largely corresponds to that according to FIGS. 3, 4.

Bei dem Beispiel nach Fig. 7, 8 ist eine quadratische, innere Begrenzung der Luftstrahlöffnung 2 entsprechend Fig. 5, 6 angewendet. Im übrigen ist ein nicht durchgehender Ausgleichsschlitz 5 angebracht.In the example according to FIGS. 7, 8, a square inner boundary of the air jet opening 2 according to FIGS. 5, 6 is used. Otherwise, a non-continuous compensation slot 5 is provided.

Ferner ist bei dem Beispiel nach Fig. 9 angedeutet, wie in demjenigen Bereich 29 der inneren Begrenzung 3 der Luftstrahlöffnung 2, welcher dem Fadenaustrittsschlitz 4 gegenüberliegt, zwei Druckausgleichschlitze 5 angeordnet werden können, die jeweils in einem Bogenabstand von etwa 150° vom Austrittsschlitz 4 entfernt liegen. Die Schlitze 5 nach Fig. 9 sind symmetrisch zu der durch den Schlitz 4 und die Schusslinie 6 gehenden, in Fig. 9 gestrichelt angedeuteten Geraden 35 angeordnet, besitzen also gleichen Bogenabstand von dieser. Auch bei dieser Bauart lässt sich durch die Anordnung der beiden Schlitze 5 ein Druckausgleich auf der dem Fadenaustrittsschlitz 4 gegenüberliegenden Seite der Schusslinie 6 erzielen, wodurch sich Luftstrahl und Schussfaden 28 während des Eintrages zentrieren lassen.Furthermore, in the example according to FIG. 9 it is indicated how two pressure compensation slots 5 can be arranged in that area 29 of the inner boundary 3 of the air jet opening 2, which is opposite the thread outlet slot 4, each of which is at an arc distance of approximately 150 ° from the outlet slot 4 lie. The slots 5 according to FIG. 9 are arranged symmetrically to the straight line 35, which is indicated by the dashed line in FIG. 9, and thus have the same arc distance from the latter. With this design too, the arrangement of the two slots 5 allows pressure equalization to be achieved on the side of the weft line 6 opposite the thread outlet slot 4, as a result of which the air jet and weft thread 28 can be centered during the entry.

Bei dem Beispiel nach Fig. 10 ist die Luftstrahlöffnung 2 bei 37 V-förmig ausgebildet. Auch die Druckausgleichausnehmung 5a ist V-förmig gestaltet. Die Weite b beim Beginn derAusnehmung 5a ist grösser als die Weite a des Fadenaustrittsschlitzes 4. Der Druckausgleich lässt sich dadurch besonders wirksam gestalten.In the example according to FIG. 10, the air jet opening 2 is formed in a V shape at 37. The pressure compensation recess 5a is also V-shaped. The width b at the beginning of the recess 5a is larger than the width a of the thread outlet slot 4. The pressure compensation can thus be designed to be particularly effective.

Bei Anbringung der Zahnelemente 1 in einer Luftstrahl-Oüsenwebmaschine werden die Zahnelemente entsprechend Fig. 11, 12 auf der Lade 21 der Webmaschine befestigt, auf der auch das Riet 22 angebracht ist. Beim Schusseintrag ragen die Zahnelemente 1 entsprechend Fig. 10 in das von den Kettfäden 25,26 gebildete Webfach 27 hinein. Der Schussfaden 28 wird in Zentrum 6 (Schusslinie) der Öffnung 2 der Elemente eingetragen. Während des Eintrags kann der Faden 28 besonders gut zentriert werden, weil jedes Element 1 Druckausgleichsschlitze 5 aufweist.When attaching the tooth elements 1 in an air jet loom, the tooth elements are fastened according to FIGS. 11, 12 on the drawer 21 of the weaving machine, on which the reed 22 is also attached. 10, the tooth elements 1 protrude into the shed 27 formed by the warp threads 25, 26. The weft thread 28 is inserted in the center 6 (weft line) of the opening 2 of the elements. During the entry, the thread 28 can be centered particularly well because each element has 1 pressure compensation slots 5.

Bei dem folgenden, dem Pfeil 30 entsprechenden Rietanschlag werden die Teile 1, 22, 21 in Fig. 10 nach links verschwenkt, so dass der Schussfaden 28 an der Anschlagstelle 31 zur Entstehung des Gewebes 32 angeschlagen wird. Der Faden 28 wird mittels einer ausserhalb des Webfaches 27 angeordneten Luftdüse 33 (Fig. 11) durch das Fach geschossen.In the following reed stop corresponding to the arrow 30, the parts 1, 22, 21 in FIG. 10 are pivoted to the left, so that the weft thread 28 is struck at the stop point 31 to create the fabric 32. The thread 28 is shot through the compartment by means of an air nozzle 33 (FIG. 11) arranged outside the shed 27.

Bei allen Ausführungsformen sind ein oder mehrere Druckausgleichsschlitze 5, 9 zusätzlich zu dem Fadenaustrittsschlitz 4 in der Luftstrahlöffnung 2 angebracht, und zwar sind diese Druckausgleichsschlitze im wesentlichen gegenüber dem Fadenaustrittsschlitz 4 angeordnet, so dass eine symmetrische Kraftwirkung auf die Schusslinie 6 bzw. den einzutragenden Schussfaden 28 entsteht und dieser während des Eintrages zentriert wird.In all embodiments, one or more pressure compensation slots 5, 9 are provided in addition to the thread exit slot 4 in the air jet opening 2, specifically these pressure compensation slots are arranged opposite the thread exit slot 4, so that a symmetrical force effect on the weft line 6 or the weft thread 28 to be inserted arises and this is centered during the entry.
