Description

Die Erfindung bezieht sich auf eine Luftleistenlegervorrichtung für Webmaschinen gemäss den Oberbegriff von Anspruch 1.The invention relates to an air bar laying device for weaving machines according to the preamble of claim 1.

Aus der Offenlegungsschrift EP-0-149-969 ist eine Luftleistenlegervorrichtung bekannt, die das Schussfadenende vorübergehend mit einer Fangdüse hält, bis es mittels einer Einfädeldüse durch die Öse einer Leistenlegernadel geblasen wird. Daraufhin wird das Schussfadenende durch die Leistenlegernadel ins Webfach eingelegt.From the published patent application EP-0-149-969 an air bar laying device is known which temporarily holds the weft thread end with a catch nozzle until it is blown through the eyelet of a groin needle using a threading nozzle. The weft end is then inserted into the shed through the selvage needle.

Die dabei offenbarte Anordnung von bezüglich der Längsachse der Düsen parallel versetzten Fang- und Einfädeldüse weist den Nachteil auf, dass ein relativ langes Schussfadenende für ein sicheres Einfädeln in die Öse erforderlich ist, was eine relativ breite Webkante zur Folge hat. Diese Anordnung der Düsen bedingt zudem einen relativ schweren Träger für die Düsen. Eine weitere, im gleichen Dokument offenbarte Anordnung mit unmittelbar übereinander, auf der gleichen Achse angeordneten Düsen erlaubt kürzere Schussfadenende, wobei der Nachteil besteht, dass jede der beiden Düsen in den jeweils der gegenseitigen Düse vorgelagerten Fangkanal Schmutz fördert, der während dem Betrieb der Webmaschine nicht beseitigt werden kann. Der sich bildende Luftstau kann ein sicheres Einfädeln des Schussfadenendes behindern.The arrangement of the catching and threading nozzle offset parallel to the longitudinal axis of the nozzles has the disadvantage that a relatively long weft thread end is required for safe threading into the eyelet, which results in a relatively wide selvedge. This arrangement of the nozzles also requires a relatively heavy support for the nozzles. Another arrangement disclosed in the same document, with nozzles arranged directly one above the other, on the same axis, allows shorter weft ends, with the disadvantage that each of the two nozzles conveys dirt in the catch channel upstream of the mutual nozzle, which does not cause dirt during operation of the weaving machine can be eliminated. The air jam that forms can hinder the safe threading of the weft end.

Der Erfindung liegt die Aufgabe zugrunde, eine bezüglich dieser Aspekte verbesserte Vorrichtung zu schaffen.The object of the invention is to create a device which is improved with regard to these aspects.

Die Erfindung löst die Aufgabe gemäss den kennzeichnenden Merkmalen von Anspruch 1.The invention achieves the object according to the characterizing features of claim 1.

In einer Leistenlegervorrichtung sind eine Fangdüse mit einem in der achsialen Verlängerung der Düse liegenden Fangkanal sowie eine Einfädeldüse mit einem in der achsialen Verlängerung der Düse liegenden Fangkanal mit sich überkreuzenden Luftstrahlachsen in einem Träger angeordnet, was eine schmale Bauweise der Vorrichtung zum Einfädeln des Schussfadenendes in die Öse bezw. den Haken der Leistenlegernadel und somit kurze Schussfadenende respektiv schmale Webkanten ermöglicht. Schmutzteile wie Fadenflug werden zuverlässig aus dem Spalt des Trägers sowie aus den Fangkanälen abgeführt und die Bildung eines Luftstaus wird verhindert. Die kompakte Anordnung erlaubt die Masse der Düsen sowie des Trägers zu reduzieren, weshalb für das Positionieren des Trägers schnellere Bewegungen möglich sind.In a strip laying device, a catch nozzle with a catch channel lying in the axial extension of the nozzle and a threading nozzle with a catch channel lying in the axial extension of the nozzle with intersecting air jet axes are arranged in a carrier, which is a narrow construction of the device for threading the weft end into the Eyelet or the hook of the groin needle and thus short weft ends or narrow selvedges. Dirt particles such as thread flight are reliably removed from the carrier's gap and from the trap channels and the formation of an air jam is prevented. The compact arrangement allows the mass of the nozzles and the carrier to be reduced, which is why faster movements are possible for positioning the carrier.

Ein Webfach 31, in welches ein Schussfaden 21 eingetragen wird, ist durch Hochfachkettfäden 32 sowie Tieffachkettfäden 33 gebildet. Nicht dargestellt sind in Fig. 1 Randkettfäden respektiv eine Haltedüse, die den Schussfaden bezw. das Schussfadenende bis zum Schneid- und Einfädelvorgang halten. Die um den Drehpunkt 12 drehbare Leistenlegernadel 11a mit Spitze 13 und Öse 14 ist, wie mit der Stellung der Leistenlegernadel 11b angedeutet, in das Webfach 31 einführbar. Die Öse 14 kann auch einseitig offen als Haken ausgebildet sein. Der Übersichtlichkeit halber ist nur die Einfädeldüse 41 mit Fluidzuleitung 43 sowie der achsial zur Einfädeldüse 41 gegenüberliegende Fangkanal 42 dargestellt. Das nach dem Schneidvorgang resultierende Schussfadenende 21a wird durch die Einfädeldüse 41 z.B. mittels eines in der Fluidleitung 43 angedeuteten Fluidstromes, z.B. mit Luft, durch die Öse der Leistenlegernadel 11b in den Fangkanal 42 geblasen.A shed 31, in which a weft thread 21 is inserted, is formed by high shed warp threads 32 and deep shed warp threads 33. Not shown in Fig. 1 edge warp threads or a holding nozzle, respectively, the weft. the weft end up to the cutting and threading process hold. The selvage needle 11a with tip 13 and eyelet 14, which can be rotated about the pivot point 12, can be inserted into the shed 31, as indicated by the position of the selvage needle 11b. The eyelet 14 can also be designed as a hook open on one side. For the sake of clarity, only the threading nozzle 41 with the fluid supply line 43 and the catch channel 42 opposite to the threading nozzle 41 are shown. The weft thread end 21a resulting after the cutting process is blown through the threading nozzle 41, for example by means of a fluid flow indicated in the fluid line 43, for example with air, through the eyelet of the groin needle 11b into the catching channel 42.

Fig. 2a zeigt im Detail die Elemente einer weiteren Luftleistenlegervorrichtung, die für den Vorgang des Einfädelns des Schussfadenendes in die Öse der Leistenlegernadel 11 von Bedeutung sind. Die beispielhafte Ausführung diese Leistenlegers mit Haltedüse 53 ist üblicherweise an der Gewebekante am Ende des Schusseintrages angeordnet. Der Träger 54 ist üblicherweise schwenkbar bezw. in Kettrichtung verschiebbar gelagert, sodass alle daran befestigten Elemente nach dem Einlegevorgang wegbewegbar sind, um z.B. den Anschlag des Webblattes nicht zu behindern. Die Einfädeldüse 41 sowie der in achsialer Verlängerung zur Düse liegende Fangkanal 42 als auch die Fangdüse 44 mit in achsialer Verlängerung zur Düse liegendem Fangkanal 45 sind mit sich überkreuzenden Luftstrahlachsen im Träger 54 angeordnet. Die sich überkreuzenden Luftstrahlachsen könne sich im Raum berühren oder auch derart überkreuzend angeordnet sein, dass nur die Projektion der räumlichen Achsen auf eine Ebene eine sich berührende Überkreuzung gibt. Ebenfalls dargestellt ist die Leistenlegernadel 11, in deren Öse der Schussfaden eingefädelt wird. Randkettfäden oder z.B. eine Haltedüse 53 halten den Schussfaden 21, bis er von einer Fadenschere 52 geschnitten wird. Um nach dem Schussfadenanschlag den Schussfaden 21 genau über dem Auslass der Fangdüse 44 zu positionieren ist am Träger 54 ein Garnpositionierdraht 51 vorgesehen, der die Lage des Schussfadens 21 im Spalt 55 des Trägers 54 bestimmt. Ein derart positionierter Schussfaden 21, der durch die Haltedüse 53 gehalten wird, ist aus Figur 2b ersichtlich. Ebenso ist das Webfach 31 mit Hochfachkettfäden 32 sowie Tieffachkettfäden 33 erkennbar. Der vorgängig vom Webblatt angeschlagene Schussfaden 21 ist durch Verkreuzen der Kettfäden bezw. durch Fachwechsel im Gewebe eingebunden.2a shows in detail the elements of a further air bar laying device which are important for the process of threading the weft thread end into the eyelet of the bar laying needle 11. The exemplary embodiment of this groin layer with holding nozzle 53 is usually arranged on the fabric edge at the end of the weft insertion. The carrier 54 is usually pivotable. Slidably mounted in the warp direction so that all elements attached to it can be moved away after the insertion process, so as not, for example, to hinder the stop of the reed. The threading nozzle 41 and the catch channel 42 lying in the axial extension of the nozzle as well as the catch nozzle 44 with the catch channel 45 lying in the axial extension of the nozzle are arranged in the carrier 54 with intersecting air jet axes. The intersecting air jet axes can touch in the room or can also be arranged such that only the projection of the spatial axes onto a plane gives a touching intersection. Also shown is the groin needle 11, in the eyelet of which the weft thread is threaded. Edge warp threads or, for example, a holding nozzle 53 hold the weft thread 21 until it is cut by a thread scissors 52. To weft 21 after the weft stop just above the outlet of the catch nozzle 44 position, a yarn positioning wire 51 is provided on the carrier 54, which determines the position of the weft thread 21 in the gap 55 of the carrier 54. A weft thread 21 positioned in this way, which is held by the holding nozzle 53, can be seen from FIG. 2b. The shed 31 with high shed warp threads 32 and deep shed warp threads 33 can also be seen. The weft thread 21 previously struck by the reed is or be crossed by crossing the warp threads. integrated in the tissue by changing the subject.

Wie in Fig. 2c dargestellt wird die Fangdüse 44 mit Luft beschickt, der Schussfaden 21 durch die Fadenschere 52 geschnitten, und das Schussfadenende in den Fangkanal 45 eingeblasen. Dabei kommt ein Teilstück des Schussfadenendes vor den Auslass der Einfädeldüse 41 zu liegen. Die Leistenlegernadel 11 wird danach derart in den Spalt 55 des Trägers 54 eingeschwenkt, dass die Öse 14 über der Öffnung des Fangkanales 42 zu liegen kommt. Durch die Aktivierung der Einfädeldüse 41 wird, wie in Fig. 2d dargestellt, das Schussfadenende 21a durch den Luftstrom aus dem Fangkanal 45 herausgezogen und über die Öse 14 in den Fangkanal 42 geblasen. Das Schussfadenende wird darauf durch die Leistenlegernadel 11 ins Webfach 31 eingelegt, und somit die Webkante gebildet.As shown in FIG. 2c, the catching nozzle 44 is charged with air, the weft thread 21 is cut by the thread scissors 52, and the end of the weft thread is blown into the catching channel 45. A portion of the weft end comes to lie in front of the outlet of the threading nozzle 41. The groin needle 11 is then pivoted into the gap 55 of the carrier 54 such that the eyelet 14 comes to rest over the opening of the catch channel 42. By activating the threading nozzle 41, as shown in FIG. 2d, the weft thread end 21a is pulled out of the catching channel 45 by the air flow and blown into the catching channel 42 via the eyelet 14. The weft end is then inserted into the shed 31 by the selvage needle 11 and the selvedge is thus formed.

Die Stellung der Hochfachkettfäden 32 sowie der Tieffachkettfäden 33 des Webfaches 31 sind in den Figuren 2b-2d immer in der gleichen Position dargestellt. Die Stellung der Kettfäden beziehungsweise des Faches 31 kann sich natürlich während dem Schneid- und Einlegevorgang auch verändern.The position of the high shed warp threads 32 and of the deep shed warp threads 33 of the shed 31 are always shown in the same position in FIGS. 2b-2d. The position of the warp threads or the compartment 31 can of course also change during the cutting and insertion process.

Die erfindungsgemässe Leistenlegervorrichtung lässt sich natürlich nicht nur mit Luft sondern auch mit weiteren Fluiden wie z.B. Wasser betreiben.The strip laying device according to the invention can of course be operated not only with air but also with other fluids such as water.

Fig. 3 zeigt eine Aufsicht des Spaltes 55 im Träger 54 sowie die Anordnung des Garnpositionierdrahtes 51, der Öffnung der Fangdüse 44 und der Öffnung des Fangkanales 42. Die Öffnungen 42 und 44 sind vorzugsweise parallel oder annähern parallel zum Verlauf der Kettfäden angeordnet, um kurze Schussfadenenden zu erzielen. Die Lage der Öffnung der Fangdüse 44 respektiv der Einfädeldüse 41 wird zudem derart gewählt, dass das zu befördernde Schussfadenende 21a vorteilhaft in den Luftstrahl der Düse zu liegen kommt. Jede der sich überkreuzenden Luftstrahlachsen der beiden Düsen 41 und 44 kann in einer Ebene parallel zur Richtung der Kettfäden, parallel zur Eintragsrichtung des Schussfadens 21 oder in einer Ebene eines Zwischenbereiches zwischen diesen beiden Positionen liegen. Die Eintrittsöffnungen der Fangkanäle 42 und 45 sind üblicherweise achsial fluchtend zur gegenüberliegenden Düse angeordnet, wobei der weitere Verlauf der Fangkanäle in gerader oder gekrümmter Form ausgeführt sein kann.Fig. 3 shows a top view of the gap 55 in the carrier 54 as well as the arrangement of the yarn positioning wire 51, the opening of the catching nozzle 44 and the opening of the catching channel 42. The openings 42 and 44 are preferably arranged in parallel or approximately parallel to the course of the warp threads, in short To achieve weft ends. The position of the opening of the catching nozzle 44 and of the threading nozzle 41 is also selected such that the weft thread end 21a to be conveyed advantageously lies in the air jet of the nozzle. Each of the intersecting air jet axes of the two nozzles 41 and 44 can lie in a plane parallel to the direction of the warp threads, parallel to the insertion direction of the weft thread 21 or in a plane of an intermediate region between these two positions. The inlet openings of the catch channels 42 and 45 are usually arranged axially in alignment with the opposite nozzle, and the further course of the catch channels can be designed in a straight or curved shape.

Die Anordnung der beiden Düsen 41 und 44, wie sie in den Figuren 2a-2d gezeigt wurden, kann auch gegenseitig vertauscht werden, sodass die Fangdüse 44 oben und die Einfädeldüse 41 unten zu liegen kommt.The arrangement of the two nozzles 41 and 44, as shown in FIGS. 2a-2d, can also be interchanged, so that the catch nozzle 44 comes to lie at the top and the threading nozzle 41 at the bottom.
