Description

Die Erfindung betrifft eine Hilfsblasdüse für eine Luftstrahlwebmaschine, mit einem Zuströmkanal und einer diesem gegenüber abgewinkelten Ausströmöffnung.The invention relates to an auxiliary blowing nozzle for an air jet weaving machine, with an inflow channel and an outflow opening angled relative thereto.

Eine solche Hilfsblasdüse ist z.B. in der CH-PS (= FR-PS 2 475 586), Fig. 1, offenbart. Dabei soll durch vertikales Hinaufströmen und anschliessendes Umlenken der Luft in horizontale Schrägrichtung ein schräges Einblasen in die Schusslinie bzw. in den Führungskanal erzielt werden. Diese bekannte Düse weist jedoch den Nachteil auf, dass bei der Umlenkung der Luft ein Drall entsteht, in welchem die einzelnen Strömungselemente unter Zentrifugalkrafteinwirkung stehen. Dadurch wird der Luftstrahl beim Austritt aus der Düse zyklonartig durchgewirbelt und auseinandergerissen.Such an auxiliary blowing nozzle is e.g. in CH-PS (= FR-PS 2 475 586), Fig. 1. In this case, an oblique blowing into the firing line or into the guide channel is to be achieved by vertically flowing upwards and then deflecting the air in the horizontal oblique direction. However, this known nozzle has the disadvantage that when the air is deflected, a swirl occurs in which the individual flow elements are subjected to centrifugal force. As a result, the air jet is cyclically swirled and torn apart as it exits the nozzle.

Demgegenüber ist es Aufgabe der Erfindung, die eingangs genannte Hilfsblasdüse so zu verbessern, dass statt eines auseinandergewirbelten Luftstrahls mit grossem Streuwinkel ein kohärenter Luftstrahl mit möglichst geringem Streuwinkel gebildet wird.In contrast, it is an object of the invention to improve the auxiliary blowing nozzle mentioned at the outset in such a way that a coherent air jet with the smallest possible scattering angle is formed instead of an air jet having a large scattering angle which is whirled apart.

Zur Lösung dieser Aufgabe dient die Massnahme, dass in dem der Ausströmöffnung zugewandten Endbereich des Zuströmkanals wenigstens eine sich parallel zu dessen Längsrichtung erstreckende Rippe vorgesehen ist.To achieve this object, the measure is used that in the end region of the inflow channel facing the outflow opening, at least one is parallel to its longitudinal direction device extending rib is provided.

Hierdurch lässt sich die Entstehung eines Dralls beim Umlenken der Luft wirkungsvoll verhindern, so dass der Austrittsstrahl aus praktisch gleichgerichteten Teilströmen mit optimaler Richtwirkung besteht. Somit wird eine für den Schussfadentransport maximale Schubkraft sowie Induktionswirkung erreicht.This effectively prevents the formation of a swirl when the air is deflected, so that the exit jet consists of practically rectified partial flows with optimal directivity. This ensures maximum thrust and induction for weft transport.

Nach einer besonders vorteilhaften Ausführung der Erfindung kann sich die Rippe im wesentlichen bis zur gegenüberliegenden Wand des Zuströmkanals erstrecken. Hierdurch wird eine optimale Drallverhinderung bzw. Richtwirkung bei verhältnismässig einfacher Fertigung erreicht.According to a particularly advantageous embodiment of the invention, the rib can extend essentially to the opposite wall of the inflow channel. In this way, an optimal swirl prevention or directivity is achieved with relatively simple production.

Der der Rippe zugewandte Boden des Zuströmkanals kann zur Längsmittelebene der Rippe geneigt sein. Hierdurch kann eine zusätzliche Schrägstellung bzw. Abwinkelung des Austrittstroms erreicht werden.The bottom of the inflow channel facing the rib can be inclined to the longitudinal center plane of the rib. In this way, an additional inclination or angling of the outlet flow can be achieved.

Der die Rippe umgebende Endbereich des Zuströmkanals kann zwei Teilkanäle unterschiedlichen Querschnitts aufweisen. Hierdurch lässt sich eine besonders einfache Beeinflussung des Strahlwinkels erreichen.The end region of the inflow channel surrounding the rib can have two sub-channels of different cross-section. This allows the beam angle to be influenced in a particularly simple manner.

Die Flanken der Rippe können zu deren Längsmittelebene verschieden geneigt sein. Hierdurch lässt sich die Leitwirkung der Rippe in Bezug auf den Ausströmkanal und somit die Richtwirkung zusätzlich verbessern.The flanks of the rib can be inclined differently to the longitudinal center plane thereof. In this way, the guiding effect of the rib in relation to the outflow channel and thus the directional effect can be additionally improved.

Die Länge L der Ausströmöffnung kann grösser sein als ihr halber Durchmesser d. Hierdurch lässt sich die Streuung des Austrittsstrahls zusätzlich verringern.The length L of the outflow opening can be greater than half its diameter d. As a result, the scattering of the exit jet can be reduced further.

Der der Rippe zugewandte Rand der Ausströmöffnung kann ferner gerundet sein. Hierdurch werden der wirksame Querschnitt sowie die wirksame Führungslänge der Ausströmöffnung vergrössert, womit eine zusätzliche Verstärkung der Richtwirkung erzielt werden kann.The edge of the outflow opening facing the rib can also be rounded. As a result, the effective cross section and the effective guide length of the outflow opening is enlarged, with which an additional strengthening of the directivity can be achieved.

Schliesslich kann der Endbereich des Zuströmkanals eine etwa dreieckförmige, sich in Richtung zur Ausströmöffnung hin verjüngende Abschrägung aufweisen. Hierdurch wird eine zusätzliche Optimierung der Strömungsverhältnisse in Richtung zur Ausströmöffnung hin erreicht.Finally, the end region of the inflow channel can have an approximately triangular bevel which tapers in the direction of the outflow opening. As a result, an additional optimization of the flow conditions in the direction of the outflow opening is achieved.

Am Ende jedes Eintragszyklus schliesst sich der Fadenstopper 18. Das gestreckte Schussgarn 12 wird angeschlagen und nach dem Fachschluss durch die Schneidvorrichtung 36 geschnitten. Das fertige Gewebe ist mit 37 bezeichnet.The weft yarn 12 drawn off from a supply spool 10 (FIG. 1) is guided at a constant speed over driver rollers 14, the yarn length per weft being determined by the circumference and the speed of the cutting disk 16 in accordance with the fabric width. When the thread stopper 18 is closed, the weft yarn 12 is kept ready for the weft insertion by the air flow from an auxiliary nozzle 20 in the form of a yarn loop 22 in the blow thread store 24. Immediately before the thread stopper 18 opens, the begins To blow the main nozzle 26 j, the air supply of which is indicated according to arrow 25, so that the weft yarn 12 starts to move when the thread stopper 18 is opened. The yarn loop 22 is removed and the weft yarn 12 is blown into the guide channel 28 of the reed 30 with the shed 27 open, the air outlet streams 32 of the auxiliary blowing nozzles 34 arranged as relay nozzles now carrying the weft yarn 12 through the shed 27. At the end of each entry cycle, the thread stopper 18 closes. The stretched weft yarn 12 is cast on and cut by the cutting device 36 after the shed is closed. The finished fabric is designated 37.

Die Hilfsblasdüse 34 (Fig. 2, 3) weist einen Zuströmkanal 38 auf, welcher im Bereich vor der Ausströmöffnung 40 in an sich bekannter Art eine Verengung 42 aufweist.The auxiliary blowing nozzle 34 (FIGS. 2, 3) has an inflow channel 38 which has a constriction 42 in the area in front of the outflow opening 40 in a manner known per se.

In dem der Ausströmöffnung zugewandten Endbereich 44 des Zuströmkanals 38 befindet sich eine sich parallel zu dessen Längsrichtung erstreckende Rippe 46 (Fig. 3), welche sich im wesentlichen bis zur gegenüberliegenden Wand 47 des Zuströmkanals 38 erstreckt.In the end region 44 of the inflow channel 38 facing the outflow opening there is a rib 46 (FIG. 3) which extends parallel to its longitudinal direction and extends essentially up to the opposite wall 47 of the inflow channel 38.

Der die Rippe 46 umgebende Endbereich 44 des Zuströmkanals 38 weist dabei zwei Teilkanäle 48, 50 unterschiedlichen Querschnitts auf (Fig. 4).The end region 44 of the inflow channel 38 surrounding the rib 46 has two sub-channels 48, 50 of different cross-section (FIG. 4).

Der der Rippe 46 zugewandte Boden 52 des Zuströmkanals 38 ist dabei zur Längsmittelebene der Rippe 46 geneigt. Dabei können die Flanken 54, 56 verschieden zur Längsmittelebene geneigt sein, z.B. die Flanke 54 parallel zur ihr, die Flanke 56 in einem Winkel von ca. 15° bis 30°.The bottom 52 of the inflow channel 38 facing the rib 46 is inclined to the longitudinal center plane of the rib 46.
