り容易に行われる。As a conventional weft inserting nozzle, for example, Utility Model No. 49-1
There is something like the one shown in No. 8542. That is, as shown in FIG. 5, what is disclosed in the above-mentioned publication is a needle 3 having a thread passage hole 2 in the center of the nozzle body 1 through which the weft thread is passed.
The inner wall of the inner surface hole 4 provided in the nozzle body 1 and the outer wall 5 of the tip of the needle 3 inserted into the inner surface hole 4 form an orifice 6 through which the pressure fluid passes. To adjust the gap between the orifice 6, move the needle 3 to the body 1.
When the needle adjustment screw 7 provided inside the needle is rotated, the tip of the needle 3 is tapered (contoured), so the tip of the needle 3 moves back and forth in the nozzle axis direction.

させるようになっている。Pressure fluid such as water or air is sent to a fluid reservoir 9 provided in the nozzle body 1 through a fluid guide pipe 8, and
The orifice 6 passes through a plurality of holes 10 provided on the circumference of the nozzle in a direction substantially perpendicular to the nozzle axis or in a direction toward the nozzle axis.
Then, it becomes a jet flow, enveloping the weft yarn Y coming out of the needle threading hole 2 and pulling it, causing it to fly into the warp opening.

に振れが生じ、オリフィス断面は片寄った間隙のリング
状となり、この中を流れる噴射流は片寄った中空流れを
形成し、ノズル軸線より外れて噴射され、緯糸は経糸開
口内の所定の経路を飛走しないという問題点があった。However, in such a conventional weft insertion nozzle, the tip of the needle 3 has a thread passage hole 2 and is hollow and thin, so it is difficult to align the fine detail with the nozzle axis completely. , and when the needle 3 is rotated to adjust the gap between the orifices 6, the tip of the needle 3 that is away from the mounting position of the needle adjustment screw 7 that restricts the rotation of the needle 3 is aligned with the needle axis. If the needle adjustment screw 7 is even slightly out of alignment or bent, or if there is even a slight gap in the needle adjustment screw 7, the needle tip will deflect, and the orifice cross section will be shaped like a ring with uneven gaps. There was a problem in that the flowing jet formed a lopsided hollow flow and was jetted away from the nozzle axis, and the weft yarn did not fly along a predetermined path within the warp opening.
又、オリフィス６に入る圧力流体は、孔１０を通り流体
貯留部９よりノズル軸線に対し直角方向から供給される
ため、ノズル軸線に平行に設けられているオリフィスに
圧力流体が入るためには直角に近く、曲がる必要があり

による噴射流の流速の低下、集束性の低下は避は難いも
のとなっていた。尚、オリフィスに入る圧力流体の入口
方向をノズル軸線に対して斜めに改善した方法も考えら
れているが、尚充分ではない。In addition, since the pressure fluid entering the orifice 6 is supplied from the fluid storage section 9 through the hole 10 in a direction perpendicular to the nozzle axis, it is necessary for the pressure fluid to enter the orifice, which is provided parallel to the nozzle axis, at right angles. Because of this, it is difficult to avoid the occurrence of fluid resistance and severe turbulence, resulting in a decrease in the velocity of the jet flow and a decrease in convergence. Although a method has been considered in which the inlet direction of the pressure fluid entering the orifice is made oblique to the nozzle axis, this method is still not sufficient.

発生等の問題点を解決しようとするものである。The present invention deals with non-uniformity of the orifice cross-sectional gap due to misalignment between the axis of the needle of the weft insertion nozzle and the axis of the nozzle, the resulting deviation in the jetting direction of the jetted water, and the refraction of the pressurized fluid entering the orifice. This aims to solve problems such as the generation of resistance and turbulence.

した。In a weft inserting nozzle for a fluid jet type shuttleless loom, a part of the needle having a weft threading hole in the center is fitted and supported in the center hole of the nozzle body, and on the other hand, the needle has an inner hole surrounding the outer periphery of the tip of the needle. The adjustment fitting is screwed into the front opening of the 7-nozzle body, and the outer periphery of the tip of the needle and the inner wall of the inner hole of the adjustment fitting form an orifice through which the pressure fluid passes, and the adjustment fitting with the inner hole is aligned with the nozzle axis. The cross-sectional area of the orifice is changed by moving it in the direction.

飛走し、かつ集束性を高めることが出来る。In the weft insertion nozzle of this invention, the tip axis of the needle is fixed using a jig in a state that is perfectly aligned with the nozzle axis, and the cross-sectional gap of the orifice (the cross-sectional area through which pressure fluid passes) can be adjusted. This is done by rotating the adjusting fitting, but since the position of the adjusting fitting adjusted by turning coincides with the position where the orifice is formed at the tip of the needle by the adjusting fitting and the needle, the cross section of the orifice due to the turning of the adjusting fitting Non-uniform fluctuations in the gap will not occur. Therefore,
The jet stream does not bend with respect to the nozzle axis, flies straight, and can be highly focused.

の整流孔又は整流板を通ってオリフィスに放出される。Further, the pressure fluid sent into the fluid reservoir by the fluid guiding pipe is discharged into the orifice through a number of rectifying holes or plates provided on the orifice side surrounding the needle.

、流速が早く集束性が高い。The rectifying holes or rectifying plates are provided approximately evenly around the entire circumference of the orifice, and approximately in line with the axial direction of the orifice. As a result, the jet flow generated at this orifice is ejected from the nozzle in a stable manner without turbulence, and has a high flow velocity and high convergence.
この発明を図面に基づいて説明する。 This invention will be explained based on the drawings.

オリフィス２６を形成する。The needle 21, which is thin in its entirety and has a thread passage hole 20 through which the weft passes through the center G, is partially supported in the center hole of the nozzle body 22, while the needle 21, which is thin in its entirety, is supported in the center hole of the nozzle body 22, while inside the front opening of the nozzle body 22, in the direction of travel of the weft in the nozzle. The adjustment fitting 23 is screwed together from the opposite direction. The end of the adjustment fitting 23 that is inserted into the front opening is formed with a funnel-shaped tapered surface 25 that connects to the inner surface hole 24 and converges toward the center, and the tapered surface forms a small hole that converges. The tip of the needle 21 is inserted into the portion to form an orifice 26 for passing the jet flow between the tapered surface and the outer periphery of the needle tip.

。The small diameter portion of the nozzle body 22 is inserted into the insertion hole of the bracket 28 , the stepped portion is engaged with the bracket 28 , and the nozzle body 22 is fastened to the bracket 28 with a fixing metal fitting 29 . Pressure fluid such as water or air is sent from the fluid guide pipe 3o to a fluid reservoir 31 provided within the nozzle body. The fluid storage section 31 is provided close to the nozzle center axis because the needle does not rotate and the diameter of the needle can be made small. The jet flow passes through the plurality of rectifying holes 32 and reaches the orifice, enveloping the weft yarn Y and pulling it to fly into the warp opening.The rectifying holes 32 are, as shown in FIG. 31
However, in order to further enhance the rectification effect, instead of the rectification holes 32, holes radially extending from the nozzle axis are formed as shown in FIG. A rectifying plate 33 having many elongated holes may be fitted.

The other end of the needle 21 is press-fitted or shrink-fitted into the center hole of the body 22, or fixed using a strong adhesive (for example, an epoxy synthetic resin adhesive). As an example of another method, as shown in FIG. 4, a needle 34 with a stepped end on the opposite side of the orifice is inserted into the center hole of a seven-hole body 35, and then tightened with a set screw 36, and the needle 34 is Another possible method is to provide support.

直進性が確実となり集束性も向上する。According to the present invention, in a weft insertion nozzle for a fluid jet type shuttleless loom, a part of the needle having a weft passing hole in the center is fitted and supported in a nozzle body, and an inner hole surrounding the outer periphery of the tip portion of the needle is fitted and supported. An adjustment fitting having a diameter is screwed onto the front opening of the nozzle body, and the outer periphery of the tip of the needle and the inner wall of the inner hole of the adjustment fitting form an orifice through which the pressure fluid from the fluid reservoir passes. Since the orifice cross-sectional area can be changed by moving the nozzle in the axial direction, the axis of the needle tip is reliably on the nozzle center line, and the needle itself does not rotate, so the orifice cross-section can be changed due to deflection of the needle tip, etc. Non-uniformity of the gap does not occur, and therefore, the straightness of the jet flow with respect to the nozzle axis is ensured, and the focusing property is also improved.
又、圧力流体は流体貯留部からほぼオリフィスの軸線方
向に沿い整流されつつオリフィスに入るので、噴射流の
流速の増大、集束性の向上が可能である。In addition, since the pressure fluid enters the orifice from the fluid reservoir while being rectified approximately along the axial direction of the orifice, it is possible to increase the flow velocity of the jet flow and improve the focusing property.

させることが出来る。In other words, it has become possible to make the needle thinner and reduce the overall outer diameter of the weft insertion nozzle, so weft insertion can be performed by arranging multiple weft insertion nozzles to the side of the warp opening, as in the case of multicolor weft insertion. In such cases, if the weft insertion nozzle is moved, the moving distance can be reduced, and if the weft insertion nozzles are arranged in a fixed manner, there is less deviation in the weft insertion position, so weft insertion stability can be increased.

なっている。そして流体が空気の場合も略同様である。Furthermore, if the fluid is water, the weft insertion nozzle has an orifice forming part at the needle tip with an inner diameter of 1.2 to 1.6 x m+.
The outer diameter is 1.6~2. Orun, its wall thickness is 0.2 m
The length is about 7 to 10101 nm, the outer circumference of the orifice is 2.4 to 2.8 mm, and the gap in the cross section of the orifice is about 0.4 mm. In order to change the cross-sectional area of the orifice, when the needle moves while rotating as in the past, the gap between the cross-sections of the orifice must be uniform, so the manufacturing precision is extremely strict, and the In order to withstand contact friction, it is necessary to harden the material with high wear resistance, and the manufacturing technology for this part of the weft insertion nozzle requires an unprecedented level of sophistication, making the weft insertion nozzle very expensive. It becomes. The same applies when the fluid is air.

緯入れノズルを提供することも可能となった。The present invention has overcome this difficulty by fixing the needle to the nozzle body using a jig, and has therefore become able to provide an inexpensive weft inserting nozzle.
