本考案は、空気噴射式織機の緯入案内装置、更
に詳しくは、緯糸飛走路の幅員を調節可能な緯入
案内装置に関するものである。[Detailed Description of the Invention] The present invention relates to a weft insertion guide device for an air injection loom, and more particularly to a weft insertion guide device that is capable of adjusting the width of a weft flight path.

緯糸飛走路を進行する。従来、緯糸の飛走路は、
筬羽の織前側に一体的に突設した一対の凸曲部

6787号及び特開昭49−54671号参照）が、かゝる
方式においては通常、その溝底域により筬打ちを
行なわせる関係上、高度の形態精度が要求される
だけでなく、経糸種類により種々の厚みをもたせ
る必要があるが、当該飛走路の幅員Ｄは全く変更
することが出来なくなつている。 Generally, in an air-jet loom, weft insertion is performed using an air jet, and the weft yarn advances along the weft flight path when flying in front of the reed. Conventionally, the weft flight path was
A U-shaped channel (see Fig. 1) formed between a pair of convex curved parts a and b integrally protruding from the front side of the reed has become common (Tokuko Sho 54-
6787 and Japanese Unexamined Patent Publication No. 49-54671), in such a method, not only a high degree of form accuracy is required because beating is performed using the groove bottom area, but also a high degree of accuracy is required depending on the warp type. Although it is necessary to provide various thicknesses, it has become impossible to change the width D of the flight path at all.
しかしながら、かゝる飛走路を通過する緯糸が
幾分蛇行するために、該緯糸飛走状態は緯糸種類
によつて色々変化する。このため、緯糸種によつ
ては緯糸の毛羽立ち又は、フイラメント割れや、
更に緯入不良などといつたトラブルを起こす惧れ
が多分にあつたのである。 However, since the weft thread passing through such a flight path meanderes to some extent, the weft flight state varies depending on the type of weft thread. For this reason, depending on the weft type, weft fuzzing or filament cracking may occur.
Furthermore, there was a high risk of problems such as poor weft insertion.
本考案者は、緯糸種により最適な上下方向幅に
緯糸飛走路の幅員を設定すれば、上述の欠点が解
消できることに着目し、主筬の織前側に１つの凸
曲部を突設する一方、該凸曲部の下面側に相対的
に上下移動可能な補助筬羽を並設するという技術
手段を採用することによつて、飛走路の幅員を調
節出来るようにしたものである。 The inventor of the present invention focused on the fact that the above-mentioned drawbacks can be overcome by setting the width of the weft thread flight path to the optimum width in the vertical direction depending on the weft type. The width of the flying path can be adjusted by adopting a technical means of arranging auxiliary reed blades that are relatively movable up and down in parallel on the lower surface side of the convex curved portion.
以下、本考案を添附図面に示す実施例に基いて
詳しく説明する。 Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings.

節できるようになつている。 Fig. 2 is a perspective view of a weft entry guide device that constitutes a weft flight path 4 by reed blades 2, 2, . shows. That is, the reed feathers 2, 2, . Auxiliary reed wings 3, 3 made of springy material
. . . is held at its lower end together with the rim 5 of the reed, and can be finely adjusted forward and backward, and also has an adjuster bolt 7.
constitutes an auxiliary reed B which is slidable in the vertical direction in which the reed blade 2 extends, and is formed by a convex curved portion 2a of the reed blade 2 and a convex curved portion 2b of the auxiliary reed blade 3, as shown in FIG. The vertical width of the weft running path 4 can be adjusted from D to D'.

る）、緯糸を毛羽立てたり、又は、フイラメント
割れを起こさせるだけでなく、緯糸飛走を阻害し
て緯入れ不良を生じさせる場合がある。 By the way, in the air injection type loom, the weft thread is blown into the weft track 4 by riding on an air jet jetted from a main nozzle (not shown) in the direction of the arrow X toward the starting end of the weft track 4. By means of auxiliary jets from sub-nozzles (not shown) arranged at regular intervals along the line, the weft flies while contacting the upper and lower sides of the flying path 4 in a meandering manner, reaches the end, and weft insertion is completed. It's about to be completed. This meandering pitch differs depending on the type of weft yarn, and if the vertical width of the flying path 4 is fixed as in the past, as shown in Fig. 4, the vertical width D is appropriate for the spun yarn (solid line). If present, filament yarn (dotted line)
In other words, the width in the vertical direction is narrow, and the opportunity for contact with the upper and lower sides of the flight path 4 and the contact range L are large (in the case of spun yarn, the upper side of the flight path 4 is just at the meandering apex). However, in the case of filament yarns, it contacts the upper and lower sides of the flight path 4 even before and after the meandering apex), which not only fluffs the weft or causes filament cracking. , which may impede weft flight and cause weft insertion defects.

る。 On the other hand, in the present invention, since the vertical width of the weft thread path 4 can be adjusted from D to D', as shown in Fig. 4, the filament yarn (dotted line) In this case, the weft flight path 4
If the width in the vertical direction is increased, as shown in FIG. 5, the threads will not come into sliding contact with the upper and lower sides of the weft flight path 4 before and after the meandering apex, but will come into contact only at the meandering apex. Therefore, it is possible to prevent unnecessary contact action from occurring, and it is possible to eliminate fuzzing of the weft yarns and poor weft insertion.
また、この緯糸飛走路４の調節効果は筬打ち時
に織口が飛走路４に接触して発生する毛羽立ち等
の織物不良を解消することにもなる。 Furthermore, the effect of adjusting the weft running path 4 also eliminates fabric defects such as fluffing that occurs when the weft edge comes into contact with the running path 4 during beating.
更に、本考案においては、補助筬羽は筬打ちと
は直接関係せず、主筬によつて筬打ちがなされる
ため、経糸種、織物種によつて主筬羽の厚みのみ

上下方向幅を調節できるので、筬羽の緯糸飛走路
の幅を固定するような筬での上記欠点をなくする
ことができる。 Furthermore, in the present invention, the auxiliary reed feathers are not directly related to reed beating, and the beating is performed by the main reed, so that only the thickness of the main reed feathers can be changed depending on the warp type and fabric type. Since the vertical width of the weft running path 4 can be adjusted as described above, it is possible to eliminate the above-mentioned drawbacks of reeds in which the width of the weft running path of the reed feathers is fixed.
また更に、本考案においては、飛走路は主筬と
補助筬羽とにより形成し得るため、加工容易性も
向上し、工業上極めて実際的な緯入案内装置を提
供できる利点もある。 Furthermore, in the present invention, since the flying path can be formed by the main reed and the auxiliary reed blades, the ease of processing is improved, and there is also the advantage that it is possible to provide an industrially very practical weft insertion guide device.

選ばれてよい。 Although the present invention has been described above using preferred specific examples, the present invention is not limited to the above-mentioned specific examples.The present invention is not limited to the above-mentioned specific examples, and the present invention constitutes a reed groove whose vertical width can be adjusted by a combination of the main reed blade and the auxiliary reed blade. It should be understood that it falls within the technical scope of the present invention. Therefore, in the above specific example, the auxiliary reed blades are arranged opposite to the main reed blades, but the auxiliary reed blades may be arranged at regular intervals. Further, the auxiliary reed blades may be adjusted integrally with an adjusting bolt, or, for example, the effective passing width or reed passing width may be divided into blocks by the auxiliary nozzle arrangement interval, and adjusted for each square block. You may also do so. Furthermore, the form of the auxiliary reed blades is not limited to that shown in the drawings, and may be selected so as to form various reed groove shapes.
