Description

Die Erfindung betrifft eine Webmaschine mit einer während des Schusseintrages ausserhalb des Webfaches verbleibenden Schussfaden-Vorratsspule, von der der Faden während des Eintrags abgezogen wird, und mit einer Leistenlegernadel zum Einlegen der ausserhalb des Faches befindlichen Schussfadenendes in ein folgendes Fach.The invention relates to a weaving machine with a weft supply spool remaining outside the shed during the weft insertion, from which the thread is drawn off during the entry, and with a selvage needle for inserting the weft end located outside the compartment into a following compartment.

Bei einer bisherigen Webmaschine dieser Art (DE-C-1 710 353 wird das Schussfadenende mittels einer Randfadenklemme gehalten, über die mit einem Haken versehene Leistenlegernadel geführt und von ihr anschliessend in das Webfach eingelegt. Die mechanische Bewegung der Randfadenklemme und die anschliessende Uebergabe des Schussfadenendes an die Leistenlegernadel erfordern relativ viel Zeit innerhalb des Arbeitsspieles der Webmaschine. Einer Steigerung der Drehzahl einer Webmaschine sind u.a. durch diesen Fadenübergabevorgang gewisse Grenzen gesetzt.In a previous weaving machine of this type (DE-C-1 710 353), the end of the weft thread is held by means of an edge thread clamp, is guided over the bar-laid selvage needle and then inserted into the shed by the latter. The mechanical movement of the edge thread clamp and the subsequent transfer of the weft end to the selvage needle take a relatively long time within the working cycle of the weaving machine.

Der Erfindung liegt die Aufgabe zugrunde, eine besonders in dieser Hinsicht verbesserte Maschine zu schaffen.The invention has for its object to provide a particularly improved machine in this regard.

Die Erfindung ist gekennzeichnet durch eine Luftdüse, vorzugsweise Blasdüse, zum Ueberführen des Schussfadenendes auf die Leistenlegernadel. Wie die Versuche ergaben, lässt sich das Schussfadenende auf diese Weise in ganz besonders kurzer Zeit der Leistenlegernadel übergeben. Durch die Uebergabe des Schussfadenendes an die Leistenlegernadel mittels Luft werden daher höhere Drehzahlen der Webmaschine ermöglicht.The invention is characterized by an air nozzle, preferably a blowing nozzle, for transferring the weft end to the groin needle. As the tests showed, the weft end can be handed over to the groin needle in a particularly short time. By transferring the weft end to the groin needle by air, higher speeds of the weaving machine are therefore made possible.

Die als Ganzes mit 31 bezeichnete Webmaschine enthält zwei Maschinenwangen 32, 33. Dazwischen sind ein Warenbaum 34 und ein Riet 35 angeordnet. Der Schussfaden 36 wird von einer ortsfesten Spule 37 abgezogen, durch eine Schussfadenbremse 38 geleitet und von einer ausserhalb des Webfaches 65 (Webbreite W) befindlichen Haupteintragsdüse 39 eingeblasen. Ueber die Webbreite W verteilt sind Hilfsdüsen 1 angeordnet, die während des Schusseintrages in das Webfach 65 hineinragen. Auf der Fangseite 41 ist eine Saugdüse 42 angeordnet.The weaving machine, designated as a whole by 31, contains two machine cheeks 32, 33. A goods tree 34 and a reed 35 are arranged between them. The weft 36 is drawn off from a stationary spool 37, passed through a weft brake 38 and blown in from a main entry nozzle 39 located outside the shed 65 (weaving width W). Auxiliary nozzles 1 are arranged over the weaving width W and protrude into the shed 65 during the weft insertion. A suction nozzle 42 is arranged on the catch side 41.

Die Düsen 39,1,42 sind über z.B. von einer elektronischen Steuereinrichtung 43 gesteuerte Ventile 44 an ein Luftverteilrohr 45 angeschlossen, das über eine Luftzuführungsleitung 46 von einem Druckluftbehälter (Luftquelle) 47 gespeist ist. Der Behälter 47 wird von einem nicht dargestellten Luftkompressor unter Druck gehalten.The nozzles 39,1,42 are e.g. Valves 44 controlled by an electronic control device 43 are connected to an air distribution pipe 45, which is fed via an air supply line 46 from a compressed air container (air source) 47. The container 47 is held under pressure by an air compressor, not shown.

Auf der Schußseite 61 ist eine in Figuren 1 - 3 nach oben gerichtete Blasdüse 62 angeordnet, die auf einem gemäss Pfeil 63 hin und her . bewegten Träger 64 befestigt ist. Das Webfach 65, in welches der Schussfaden 36 eingetragen wird, ist durch die Hochfachkettfäden 66 und die Tieffachkettfäden 67 gebildet. Ausserdem sind eine Anzahl Randkettfäden 68 vorhanden, durch welche die Schussfadenenden 36a festgehalten werden.On the weft side 61 there is a blowing nozzle 62 which is directed upwards in FIGS. 1-3 and which is directed back and forth on an arrow 63. moving carrier 64 is attached. The shed 65, in which the weft thread 36 is inserted, is formed by the high shed warp threads 66 and the deep shed warp threads 67. There are also a number of edge warp threads 68 by which the weft thread ends 36a are held.

Während des Eintrages eines Schussfadens 36c wird der Träger 64 mit der Düse 62 aus der vorderen, dem Riet 35 fernen, wirkungslosen Umkehrstellung nach Fig. 4 in die in Fig. 5 wiedergegebene, hintere, dem Riet 35 nahe Umkehrstellung (Wirkungsstellung) bewegt. Das freie Ende 36a des vorher eingetragenen Schussfadens 36 wird mittels der Randkettfäden 68 festgeklemmt. Eine Leistenlegernadel 72 wird dann um den Schwenkpunkt 71 gemäss Fig. 2 von oben durch die Hochfachkettfäden 66 eingeführt. Die Spitze 73 der Nadel 72 enthält eine Oese 74, deren Durchmesser grösser ist als der Durchmesser der Düse 62. Die Düse 62 steht nunmehr unmittelbar unter der Oese 74 der Nadel 72 gemäss Fig. 5. Der Schussfaden 36 wird dabei durch einen auf dem Träger 64 befestigten, mitbewegten, stiftförmigen Fadenführer 76 über die Düse 62 geführt und in dieser Position gespannt gehalten. Nunmehr wird der Schussfaden 36 durch eine Schere 77 abgeschnitten. Zugleich erhält Düse 62 Blasluft, so dass das Schussfadenende 36b in die Oese 74 der Leistenlegernadel 72 gemäss Fig. 2 eingeblasen wird.During the insertion of a weft thread 36c, the carrier 64 with the nozzle 62 is moved from the front, ineffective reversal position according to FIG. 4, which is distant from the reed 35, into the rear reversal position (operative position) shown in FIG. 5, close to the reed 35. The free end 36a of the previously inserted weft thread 36 is clamped by means of the edge warp threads 68. A selvage needle 72 is then inserted from above through the high shed threads 66 around the pivot point 71 according to FIG. 2. The tip 73 of the needle 72 contains an eyelet 74, the diameter of which is larger than the diameter of the nozzle 62. The nozzle 62 is now directly under the eyelet 74 of the needle 72 according to FIG. 5. The weft thread 36 is thereby carried on the carrier 64 attached, moving, pin-shaped thread guide 76 over the nozzle 62 and held in this position tensioned. Now the weft thread 36 is cut off by scissors 77. At the same time, nozzle 62 receives blown air, so that the weft thread end 36b is blown into the eyelet 74 of the groin needle 72 according to FIG. 2.

Anschliessend wird die Leistenlegernadel 72 entsprechend Fig. 6 nach links bewegt, so dass das Schussfadenende 36b in das Webfach 65 eingalegt wird. Während dieser Bewegung wird das Fach durch die nicht dargestellten
Webschäfte geschlossen, wodurch das Ende 36b festgeklemmt wird. Zugleich wird das Riet 35 in Fig. 3 nach rechts verschwenkt, wodurch das Ende 36b zusammen mit dem Schussfaden 36c an das Gewebe 78 beim Anschlag 79 angeschlagen wird.Subsequently, the selvage needle 72 is moved to the left according to FIG. 6, so that the weft thread end 36b is inserted into the shed 65. During this movement, the tray is not shown
Heald frames closed, thereby clamping end 36b. At the same time, the reed 35 is pivoted to the right in FIG. 3, as a result of which the end 36b together with the weft thread 36c is struck against the fabric 78 at the stop 79.

Die Leistenlegernadel 72 ist inzwischen wieder aus dem Fach 65 herausgezogen, die Blasluft in der Düse 62 ist wieder unterbrochen, der Träger 64 mit der Blasdüse 62 wird anschliessend wieder aus der hinteren Umkehrstellung (Wirkungsstellung) nach Fig. 5,6 in die vordere Umkehrstellung (Ruhestellung) nach Fig. 4 bewegt. Die Hilfsleiste 82 kann nunmehr abgeführt werden. Die Maschine ist für den dem Eintrag des Schussfadens 36c folgenden Schusseintrag bereit. Am Gewebe 78 entsteht eine Einlegleiste 81, die den Geweberand bildet.The groin needle 72 is now pulled out of the compartment 65 again, the blowing air in the nozzle 62 is interrupted again, the carrier 64 with the blowing nozzle 62 is then again from the rear reverse position (effective position) according to FIG. 4). The auxiliary bar 82 can now be removed. The machine is for that Entry of the weft 36c following the weft entry ready. An insert strip 81 is formed on the fabric 78 and forms the fabric edge.

Bei einer abgewandelten Ausführungsform (Fig. 8) besitzt die Leistenlegernadel 72 statt einer Oese 74 einen Haken 91, um den herum die Schussfadenenden 36b mittels einer entsprechend angeordneten Blasdüse 62 herumgelegt werden.In a modified embodiment (FIG. 8), the groin needle 72 has a hook 91 instead of an eyelet 74, around which the weft ends 36b are placed by means of a correspondingly arranged blowing nozzle 62.

Eine Blasdüse 62 für das Ueberführen des Schussfadenendes 36b auf die Leistenlegernadel 72 eignet sich naturgemäss insbesondere für Luftstrahlwebmaschinen, bei denen ohnedies Druckluft zur Verfügung steht und bei denen besonders hohe Drehzahlen vorliegen.A blowing nozzle 62 for transferring the weft thread end 36b to the selvage needle 72 is naturally particularly suitable for air jet weaving machines in which compressed air is available anyway and at which particularly high speeds are available.

Bei einer abgewandelten Ausführungsform ist auch auf der Fangseite 41 eine Blasdüse 62 zum Ueberführen der Schussfadenenden in eine Leistenlegernadel vorgesehen. Bei einem weiteren Ausführungsbeispiel ist eine Saugdüse statt der Blasdüse 62 benutzt, durch welche das Fadenende 36b durch die Oese 74 der Leisteniegernadel 72 hindurch gesaugt wird.In a modified embodiment, a blowing nozzle 62 is also provided on the catch side 41 for transferring the weft thread ends into a groin needle. In a further exemplary embodiment, a suction nozzle is used instead of the blowing nozzle 62, through which the thread end 36b is sucked through the eyelet 74 of the groin needle 72.

Bei einer noch anderen Bauart ist als Blasdüse eine Mehrlochdüse 62a gemäss Fig. 7 verwendet, die eine siebartige Anordnung einer grösseren Anzahl von Elementar-Düsenlöchern aufweist.In yet another design, a multi-hole nozzle 62a according to FIG. 7 is used as the blowing nozzle, which has a sieve-like arrangement of a larger number of elementary nozzle holes.
