Abstract

Auf der Fangseite (41) ist eine Haltedüse (85) vorgesehen zum Festhalten des Schussfadenendes (36d) beim Abschneiden des Schussfadens (36) mittels der Schere (77) und ausserdem eine Ueberführdüse (62). Wenn der Schussfaden (36) nach dem Abschneiden über der Ueberführdüse (62) steht, wird diese eingeschaltet und anschliessend die Haltedüse (85) abgeschaltet. Dadurch wird das Schussfadenende (36d) aus dem Fangkanal (89) der Düse (85) herausgezogen und in den Fangkanal (88) der Düse (62) eingeblasen. Bei diesem Vorgang wird das Schussfadenende (36d) durch die Oese (74) der Leistenlegernadel (72) geführt und dieser übergeben. Durch die Haltedüse (85) wird erzielt, dass das Abschneiden mittels der Schere (77) auch bereits erfolgen kann, bevor der Schussfaden (36) über der Oese (74) der Leistenlegernadel (72) und der Ueberführdüse (62) steht.On the catch side (41) there is a holding nozzle (85) for holding the weft thread end (36d) when cutting the weft thread (36) by means of the scissors (77) and also a transfer nozzle (62). If the weft thread (36) is above the transfer nozzle (62) after cutting, this is switched on and the holding nozzle (85) is then switched off. As a result, the weft thread end (36d) is pulled out of the catch channel (89) of the nozzle (85) and blown into the catch channel (88) of the nozzle (62). In this process, the weft end (36d) is passed through the eyelet (74) of the groin needle (72) and transferred to it. The holding nozzle (85) ensures that the scissors (77) can also cut off before the weft thread (36) is above the eyelet (74) of the groin needle (72) and the transfer nozzle (62).

Description

Die Erfindung betrifft eine Webmaschine mit einer während des Schusseintrages ausserhalb des Webfaches verbleibenden Schussfaden-Vorratsspule, von der der Faden während des Eintrages abgezogen wird, ferner mit einer Leistenlegernadel zum Einlegen der ausserhalb des Faches befindlichen Schussfadenenden in ein folgendes Fach, sowie mit einer Strahldüse zum Ueberführen des Schussfadenendes auf die Leistenlegernadel.The invention relates to a weaving machine with a weft supply spool remaining during the weft insertion outside of the shed, from which the thread is drawn off during the entry, also with a selvage needle for inserting the weft ends located outside the compartment into a following compartment, and with a jet nozzle for Transfer of the weft end to the groin needle.

Bei einer bisherigen Webmaschine dieser Art (EP-Anmeldung 83 810397.6 = T. 628) ist ein zusammen mit der Ueberführdüse am Rand des Gewebes in Kettrichtung hin und her verschiebbarer Fadenführer vorgesehen, durch welchen das in Randkettfäden festgehaltene Schussfadenende über die Ueberführdüse geführt und in dieser Position gespannt gehalten wird. Nunmehr wird die Ueberführdüse eingeschaltet. Erst danach kann das Schussfadenende mittels einer Schneidvorrichtung abgeschnitten und der Leistenlegernadel übergeben werden.In a previous weaving machine of this type (EP application 83 810397.6 = T. 628), a thread guide which can be moved back and forth in the warp direction together with the transfer nozzle at the edge of the fabric is provided, through which the weft thread end held in edge warp threads is guided over the transfer nozzle and in it Position is kept tense. Now the transfer nozzle is switched on. Only then can the end of the weft thread be cut off by means of a cutting device and transferred to the selvage needle.

Es liegt bei dieser Maschine der Nachteil vor, dass der Zeitpunkt, zu dem andere, sich auf die Gewebeleiste beziehende Vorgänge der Webmaschine stattfinden können, davon abhängig ist, ob der Schussfaden bereits über der Ueberführdüse steht und diese eingeschaltet ist.The disadvantage of this machine is that the point in time at which other processes of the weaving machine that relate to the fabric bar can take place depends on whether the weft thread is already above the Transfer nozzle stands and this is switched on.

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

Die Erfindung ist gekennzeichnet durch eine vor dem Einschalten der Ueberführdüse auf den Schussfaden einwirkende Haltedüse zum Festhalten des Schussfadenendes vor Ueberführen auf die Leistenlegernadel.The invention is characterized by a holding nozzle, which acts on the weft thread before the transfer nozzle is switched on, for holding the weft thread end before transferring it to the selvage needle.

Durch die Haltedüse kann dafür gesorgt werden, dass an der Gewebeleiste erforderliche Vorgänge, wie z.B. das Abschneiden des Schussfadens, unabhängig davon ausgeführt werden können, ob Schussfaden und Leistenlegernadel bereits über der Ueberführdüse stehen. Der Schussfaden lässt sich durch die Haltedüse bereits vorher fixieren, so dass er z.B. nach dem Abschneiden gespannt gehalten und über die Ueberführdüse und vor die Leistenlegernadel geführt werden kann.The holding nozzle can be used to ensure that the necessary processes, such as e.g. the cutting of the weft thread, regardless of whether the weft thread and the groin needle are already above the transfer nozzle. The weft thread can be fixed in advance by the holding nozzle, so that it e.g. after cutting it can be kept taut and passed over the transfer nozzle and in front of the groin needle.

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 in between. 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). Over the weaving width W are distributed ilfsdüsen H 1 arranged, which protrude during the weft insertion into the shed 65th 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 und der Fangseite 41 ist je eine in Fig. 1 - 3 nach oben gerichtete Blasdüse 62a,62 angeordnet, die auf einem gemäss Pfeil 63 hin und her bewegten Träger 64 befestigt ist. Träger 64 enthält ausserdem eine Haltedüse 85. Während die den Schussfaden 36 überführende Düse 62 in Fig. 2 von unten nach oben (Pfeil 86) bläst, bläst die Haltedüse 85 gemäss Pfeil 87 entgegengesetzt von oben nach unten. Der Luftstrahl von Düse 62 gelangt in einen Fangkanal 88, der Luftstrahl aus Düse 85 in einen Fangkanal 89.On the weft side 61 and the catching side 41 there is a blowing nozzle 62a, 62 which is directed upwards in FIGS. 1-3 and is fastened on a support 64 which is moved to and fro according to arrow 63. Carrier 64 also contains a holding nozzle 85. While the nozzle 62 passing over the weft thread 36 in FIG. 2 blows from bottom to top (arrow 86), the holding nozzle 85 blows in the opposite direction from arrow top to bottom. The air jet from nozzle 62 enters a catch channel 88, the air jet from nozzle 85 into a catch channel 89.

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.The shed 65, in which the weft thread 36 is inserted, is through the high shed warp threads 66 and the deep shed warp threads 67 formed. 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 den Düsen 62,85 aus der vorderen, dem Riet 35 fernen, wirkungslosen Umkehrstellung nach Fig.4 in eine in Fig. 5 wiedergegebene, dem Riet 35 nähere Mittelposition bewegt. Während dessen wird eine Leistenlegernadel 72 um den Schwenkpunkt 71 gemäss Fig. 2 im Gegenzeigersinn verschwenkt (Pfeil 90) und gelangt in eine der Fig. 5 entsprechende Mittelposition 72a nach Fig. 6. Die Spitze 73 der Nadel 72 enthält eine Oese 74, deren Durchmesser grösser ist als der Durchmesser der Düse 62.During the insertion of a weft thread 36c, the carrier 64 with the nozzles 62, 85 is moved from the front, ineffective reversed position according to FIG. 4 distant from the reed 35 into a central position shown in FIG. 5, closer to the reed 35. During this time, a groin needle 72 is pivoted counterclockwise about the pivot point 71 according to FIG. 2 (arrow 90) and reaches a central position 72a according to FIG. 5 corresponding to FIG. 6. The tip 73 of the needle 72 contains an eyelet 74, the diameter of which is larger than the diameter of the nozzle 62.

Nunmehr wird die Haltedüse 85 eingeschaltet und anschliessend der Schussfaden 36 mittels einer Schere 77 abgeschnitten. Das Schussfadenende 36d wird dadurch in den Fangkanal 89 entsprechend Fig. 6 geblasen, wodurch der Schussfaden 36 gespannt gehalten wird.Now the holding nozzle 85 is switched on and then the weft thread 36 is cut off with scissors 77. The weft thread end 36d is thereby blown into the catch channel 89 according to FIG. 6, as a result of which the weft thread 36 is kept taut.

Bei der weiteren Bewegung der Teile gelangt der Träger 64 in die Position nach Fig. 7 und die Leistenlegerhadel 72 in die Stellung 72c nach Fig. 7,9, in der ihre Oese 74 über der Ueberführdüse 62 steht.As the parts continue to move, the carrier 64 moves into the position shown in FIG. 7 and the groin laying needle 72 moves into the position 72c shown in FIG. 7.9, in which its eyelet 74 stands above the transfer nozzle 62.

Darauf wird die Ueberführdüse 62 eingeschaltet und anschliessend die Haltedüse 85 abgeschaltet. Das Schussfadenende 36d wird dadurch aus dem Kanal 89 gezogen und entsprechend Fig. 9 in Kanal 88 geleitet. Dabei wird es durch die Oese 74 geblasen und dadurch der Leistenlegernadel 72 übergeben.The transfer nozzle 62 is then switched on and the holding nozzle 85 is then switched off. The weft end 36d is thereby pulled out of the channel 89 and directed into the channel 88 according to FIG. 9. It is blown through the eyelet 74 and thereby transferred to the groin needle 72.

Anschliessend wird die Leistenlegernadel 72 in Fig. 10 nach links bewegt, so dass das Schussfadenende 36d in das Webfach 65 eingelegt wird, während die Leistenlegernadel die Position 72d durchfährt. Sie wird dabei wieder aus dem Fach 65 herausgezogen, die Blasluft in der Düse 62 wird abgeschaltet, der Träger 64 mit der Blasluft 62 wird anschliessend wieder aus der hinteren Umkehrstellung (Wirkungsstellung) nach Fig. 7,8,10 in die vordere Umkehrstellung (Ruhestellung) nach Fig. 4 bewegteSubsequently, the selvage needle 72 is moved to the left in FIG. 10, so that the weft end 36d in the Shed 65 is inserted while the groin needle moves through position 72d. It is pulled out of the compartment 65 again, the blown air in the nozzle 62 is switched off, the carrier 64 with the blown air 62 is then again from the rear reverse position (effective position) according to FIGS. 7, 8, 10 to the front reverse position (rest position 4 moved

Während dieser Bewegungen wird das Fach durch die nicht dargestellten Webschäfte geschlossen, wodurch das Ende 36d festgeklemmt wird. Zugleich wird das Riet 35 in Fig. 3 nach rechts verschwenkt, wodurch das Ende 36d zusammen mit dem Schussfaden 36c an das Gewebe 78 beim Anschlag 79 angeschlagen wird.During these movements, the shed is closed by the heald frames, not shown, whereby the end 36d is clamped. At the same time, the reed 35 is pivoted to the right in FIG. 3, as a result of which the end 36d together with the weft thread 36c is struck against the fabric 78 at the stop 79.

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 auxiliary bar 82 can now be removed. The machine is ready for the weft insertion following the insertion of the weft thread 36c. The fabric 78 e inlegleiste 81, which forms the fabric edge is formed.

Bei einer abgewandelten Ausführungsform sind die Düsen 62, 85 umgekehrt angeordnet, d.h. Düse 62 in Fig. 2 oberhalb des Schussfadens 36, Düse 85 unterhalb davon. Dann bläst die Ueberführdüse 62 in Richtung von Pfeil 87 und die Haltedüse 85 in Richtung von Pfeil 86. Die Düsen 62,85 können auch beide von ein und derselben Seite des Schussfadens 36 her blasen. Eine oder beide der Düsen 62,85 können beispielsweise auch mit Wasser gespeist werden.In a modified embodiment, the nozzles 62, 85 are arranged upside down, ie nozzle 62 in FIG. 2 above the weft thread 36, nozzle 85 below it. Then blowing the Ueberführdüse 62 in the direction of arrow 87 and the H altedüse 85 in the direction of arrow 86. The nozzles 62,85 both can blow from one and the same side of the weft thread 36 forth. One or both of the nozzles 62, 85 can also be fed with water, for example.

Bei einer noch anderen Bauart sind die Düsen 62,85 unmittelbar übereinander angeordnet, haben also die gleiche Achse (sie fluchten miteinander). Zuerst bläst Düse 85 gegen Düse 62, wobei das Fadenende 36d in die als Fangkanal benutzte Düse 62 geblasen wird. Anschliessend wird umgesteuert und Düse 62 bläst gegen Düse 85, wobei der Faden aus Düse 62 geblasen und unter Durchsetzen der Oese 74 der Leistenlegernadel 72 in die nunmehr als Fangkanal benutzte Düse 85 eingeblasen wird. Gegebenenfalls kann dabei auch eine der Düsen mit Wasserstrahl arbeiten, die andere mit Luftstrahl.In yet another design, the nozzles 62, 85 are arranged directly one above the other, that is to say they have the same axis (they are aligned with one another). First, nozzle 85 blows against nozzle 62, the thread end 36d being blown into the nozzle 62 used as a catch channel. It is then reversed and nozzle 62 blows against nozzle 85, the The thread is blown out of the nozzle 62 and is blown into the nozzle 85, which is now used as a catch channel, while penetrating the eyelet 74 of the groin needle 72. If necessary, one of the nozzles can also work with a water jet, the other with an air jet.
