に関する。More specifically, even if the fluid consumption is low, the mixing degree is high;
The present invention relates to a yarn mixing method and device capable of reducing mixing spots.
従来１個以七の流体導入孔を内径の断面積が一様な糸通
路の側壁に開口せしめた糸条混合ノズルを使用して１本
以上のマルチフィラメント糸条を混合するに際し、該混
合ノズルの糸通路へ糸条を実質的に傾けることなく導入
し、進出する方法が広く知られている。Conventionally, when mixing one or more multifilament yarns using a yarn mixing nozzle in which one or more fluid introduction holes are opened in the side wall of a yarn passage with a uniform cross-sectional area of the inner diameter, the mixing nozzle A widely known method is to introduce and advance the yarn into the yarn path without substantially tilting it.
この方法において糸条の混合は１次のように行なわれて
いるものと推定される。In this method, it is presumed that the yarns are mixed in a first-order manner.
すなわち糸条は入口側通路、上りの排出流体により予備
開繊されて糸通路通過中に強く開繊され、流体導入孔よ
り噴出する高速流体の渦流及び乱流により糸条を構成す
る個々のフィラメントは不規則に分離され、混ぜ合わさ
れ、絡合され、固定されて混合糸となる。In other words, the yarn is pre-opened by the upward discharge fluid in the entrance side passage, and is strongly opened while passing through the yarn passage, and the individual filaments that make up the yarn are separated by the eddies and turbulence of the high-speed fluid ejected from the fluid introduction hole. are randomly separated, mixed, entangled, and fixed to form a mixed thread.
従って混合には入口側通路内での安定したしかも混合に
光分な開繊を可能とする糸通路径、流体の速度、流量、
流体導入孔付近での個々のフィラメントを不規則に混ぜ
合わせ絡合するに光分な渦流及び乱流が必要である。Therefore, for mixing, the yarn passage diameter, fluid speed, flow rate, etc. that enable stable and optical opening in the entrance passage
Light vortices and turbulence are required to randomly mix and entangle the individual filaments near the fluid introduction holes.
このため、従来の糸条混合ノズルを使用して従来の方法
で１本ないし２本以上の糸条を混合する場合、何等かの
原因で流体用力が低下したり、流体消費量を減少させよ
うとして流体圧力を低くしたり、又は流体導入孔の断面
積を小さくすると。For this reason, when mixing one or more yarns in a conventional manner using a conventional yarn mixing nozzle, the fluid utility may be reduced for some reason or the fluid consumption may be reduced. If you lower the fluid pressure or reduce the cross-sectional area of the fluid introduction hole.
入口側通路で流体速度又は流量が低下し、且つ流体導入
孔開口部での渦流及び乱流も弱くなり、光分な開繊混合
が行われなかった。The fluid velocity or flow rate decreased in the inlet side passage, and the vortex and turbulence at the opening of the fluid introduction hole also became weak, so that optical fiber opening and mixing were not performed.
従って良好な混合度を一定に保つために流体流量は多く
なり、糸条混合のためのコストは増力口した。Therefore, in order to maintain a constant good mixing degree, the fluid flow rate is increased and the cost for yarn mixing is increased.
本発明の目的は、かかる従来の糸条混合方法及び糸条混

糸条を走行せしめて混合せしめるに際し。In order to achieve such an object, the present invention provides a method of mixing yarns using a mixing nozzle, in which an inlet side passage and an outlet side passage are connected in a straight line, and the inner diameter of the outlet side passage is The cross-sectional area is 20 to 60 that of the inlet side passage.
% on the side wall of the entrance side passage of the yarn passage.
The yarn is run through a mixing nozzle having a plurality of fluid introduction holes that face each other and are opened substantially perpendicularly to the inlet side passage, and in such a way that the center line of the fluid introduction hole intersects with the center line of the inlet side passage. At least when mixing.

ドが設けられたことを特徴とする糸条混合装置。A yarn mixing method characterized in that the supply system path on the yarn entrance side is inclined by 20° to 60° with respect to the central axis of the yarn passage of the mixing nozzle, and the yarn passage is composed of an entrance side passage and an exit side passage. The inner diameter cross-sectional area of the outlet side passage is in the range of 20 to 60% of that of the inlet side passage, and there are 2 to 4 fluid introduction holes or the side wall of the inlet side passage. The fluid introduction holes are opened so that they face each other and are substantially perpendicular to the inlet passage, and the center line of the fluid introduction hole intersects with the center line of the inlet passage; A yarn mixing device characterized in that a yarn guide is provided that is inclined at 200 to 60 degrees with respect to the central axis of the yarn mixing device.
以下本発明を図面により詳細に説明する。The present invention will be explained in detail below with reference to the drawings.
なお１図は説明のためのもので１本発明の精神を逸脱し
ない限り、多少の変更は許容される。Note that FIG. 1 is for illustration purposes only, and some changes may be made without departing from the spirit of the present invention.
第１図は従来の糸条混合装置の縦断面図で１図において
糸条１がブラケット３にとりつけられたガイド２．糸通
路４．ガイド２を、糸通路４に対し実質的に傾くことな
く走行しているとき、流体が図示していない流体源から
流体導入管５．流体導入孔６を通って糸条１に吹きつけ
られて糸条１を開繊し混合する。FIG. 1 is a longitudinal sectional view of a conventional yarn mixing device. In FIG. 1, a yarn 1 is attached to a guide 2 attached to a bracket 3. Thread passage 4. When running the guide 2 substantially without tilting relative to the thread path 4, fluid flows from a fluid source (not shown) into the fluid inlet tube 5. The fluid is blown onto the yarn 1 through the fluid introduction hole 6 to open and mix the yarn 1.
流体は糸通路４の入口４ａ及び出口４ｂから排出される
。Fluid is discharged from the inlet 4a and outlet 4b of the thread passage 4.
７は混合ノズルである。ここで糸通路４の内径は一様な
断面積である。7 is a mixing nozzle. Here, the inner diameter of the thread passage 4 has a uniform cross-sectional area.
第２図及び第３図は本発明に係る糸条混合装置の一例の
縦断面図である。FIGS. 2 and 3 are longitudinal cross-sectional views of an example of a yarn mixing device according to the present invention.
第２図において糸通路１０（１出口側通路１２と入口側
通路１１とから構成されており、この出口側通路１２の
内径の断面積と入口側通路１１の内径の断面積の比は２
０〜６０％の範囲である。In FIG. 2, the yarn passage 10 (1) is composed of an exit passage 12 and an entrance passage 11, and the ratio of the cross-sectional area of the inner diameter of the exit passage 12 to the cross-sectional area of the inner diameter of the entrance passage 11 is 2.
It is in the range of 0 to 60%.
ここで内径の断面積の比を２０〜６０％の範囲に限定し
たのは、流体導入管１３から入った流体が実質的に入口
側通路１１へ流れて糸条を充分に開繊して１次の混合効
果を高め、且つ出口側通路１２への排出流体流を減少す
ることにより、混合された糸条が再び開繊され、混合度
低下を生じさせないようにするためである。The reason why the ratio of the cross-sectional area of the inner diameter is limited to the range of 20 to 60% is that the fluid entering from the fluid introduction tube 13 substantially flows into the inlet side passage 11 and fully opens the yarn. This is to enhance the subsequent mixing effect and reduce the discharge fluid flow to the outlet side passage 12 to prevent the mixed yarns from being opened again and causing a decrease in the degree of mixing.
又もう１つの目的は流体導入孔１４付近の糸条をほぼ糸
通路の中心位置にあらしめるとともに安定化するためで
ある。Another purpose is to align the yarn near the fluid introduction hole 14 to approximately the center of the yarn path and to stabilize it.
従って出口側通路１２は糸条１′がスムーズに通過出来
る断面積をもてばよい。Therefore, the outlet passage 12 only needs to have a cross-sectional area through which the yarn 1' can pass smoothly.
他方入口側通路１１の内径は、糸条１′を構成するフィ
ラメントがその通路の狭さのため、排出流体により開繊
を拘束されないような断面積が必要であり、ある程度の
大きさを有するべきである。On the other hand, the inner diameter of the inlet side passage 11 needs to have a cross-sectional area such that the filaments constituting the thread 1' are not restricted from opening by the discharge fluid due to the narrowness of the passage, and should have a certain size. It is.
例えばエステルフィラメント１５０Ｄの場合。For example, in the case of ester filament 150D.
その直径は円形モノフィラメントと仮定すると約１２５
μとなるか、この場合入口側通路１１の内径（１その１
２〜２５倍が必要である。Its diameter is approximately 125, assuming it is a circular monofilament.
μ, or in this case, the inner diameter of the inlet side passage 11 (1 part 1
2 to 25 times is required.
また、Ｒ体導入孔１４．１４は入口側通路１１に対して
ほぼ直角方向に２個開口せしめられる。Further, two R body introduction holes 14.14 are opened in a direction substantially perpendicular to the entrance side passage 11.
こう直角方向に開口せしめるのは、流体導入孔１４．１
４からの流体を最も大きな速度でお互いに衝突せしめて
強い渦流を発生させるためである。The fluid introduction hole 14.1 is opened in this perpendicular direction.
This is to cause the fluids from No. 4 to collide with each other at the highest velocity to generate a strong vortex.
そして、この流体導入孔１４の数は強い渦流を発生させ
るために２〜４個必要である。The number of fluid introduction holes 14 is required to be 2 to 4 in order to generate a strong vortex.
５個以上の場合は、工作精度及び流量増大による経済性
が問題になり、他方１個の場合は渦流が弱いという問題
が生じる。If there are five or more, there will be problems with machining accuracy and economy due to an increase in flow rate, while if there is only one, there will be a problem of weak vortex flow.
なお、流体導入孔１４．１４の中心線が入口側通路１１
の中心線と交わるようにするのは、旋回流を発生させな
いためである。Note that the center line of the fluid introduction hole 14.14 is aligned with the inlet side passage 11.
The reason for making it intersect with the center line of is to prevent swirling flow from occurring.
また入口側通路１１の内径と流体導入孔１４の内径との
比は１〜５の範囲におさめられる。Further, the ratio of the inner diameter of the inlet side passage 11 to the inner diameter of the fluid introduction hole 14 is kept in the range of 1 to 5.
これは消費流体流量の（紗と良好な渦流の発生のためで
ある。This is due to the consumption of fluid flow (gauze and the generation of a good vortex).
次に、糸入口側の供給系路と入口側通路１１の中心線と
の角度αが２０〜６０°好ましくは２０〜５５°、更に
好ましくは２０〜５０°の範囲に入るように、入口側の
ガイド８をブラケット９に取付ける。Next, the entrance side is adjusted so that the angle α between the supply system path on the yarn entrance side and the center line of the entrance side passage 11 is in the range of 20 to 60°, preferably 20 to 55°, and more preferably 20 to 50°. Attach the guide 8 to the bracket 9.
図では、ブラケット９はその部材９ａ、９ｂ及び９ｃを
４箇所のところでボルト及びナツトで止められているの
で、角度αを調節するときはナツト１７をゆるめて９ａ
又は９ｂをスライドさせれば良い。In the figure, the bracket 9 has its members 9a, 9b, and 9c fastened with bolts and nuts at four locations, so when adjusting the angle α, loosen the nut 17 and tighten the bolts 9a.
Or just slide 9b.
第３図はブラケットを除いて第２図の説明と同様である
が、第３図において角度αを調節するには、別の大小さ
まざまのブラケット９を用いれば良いことになる。3 is the same as the explanation of FIG. 2 except for the bracket, but in order to adjust the angle α in FIG. 3, it is sufficient to use other brackets 9 of various sizes.
第３図はブラケットを除いて第２図の説明と同様である
が、第３図において角度αを調節するには、別の大小さ
まざまのブラケット９を用いれば良いことになる。3 is the same as the explanation of FIG. 2 except for the bracket, but in order to adjust the angle α in FIG. 3, it is sufficient to use other brackets 9 of various sizes.
また第２゜３図において角度αを調節するのに混合ノズ
ル１５をスライドさせても良い。In addition, the mixing nozzle 15 may be slid to adjust the angle α in FIG. 2-3.
供給系路を混合ノズｌし１５の糸通路１０に対して２０
°〜６０°傾けるのは次の理由による。The supply line is connected to a mixing nozzle with 20 to 15 yarn paths 10.
The reason for tilting by 60 degrees is as follows.
一般に混合ノズル１５での混合は流体圧力を高く走行糸
の張力を低くした方が容易に行なわれるが、流体圧力を
高くすると流体消費量が多くなり、混合コストが高くな
る。Generally, mixing in the mixing nozzle 15 is easier when the fluid pressure is high and the tension of the running yarn is low, but increasing the fluid pressure increases fluid consumption and increases mixing cost.
他方張力を低くすると糸の走行が不安定になり易く１局
部的な混合斑が発生するのである。On the other hand, if the tension is lowered, the running of the yarn tends to become unstable and localized mixing spots occur.
すなわち、これまでに詳述したように混合ノズルによる
糸条の混合は混合ノズＩしの入口側通路での開繊、流体
導入孔、開口部付近での流体の渦流及び乱流に大きく左
右されるが、糸張力を低下させると入口側通路での糸条
の走行は。That is, as detailed above, the mixing of yarns by the mixing nozzle is greatly influenced by the fiber opening in the inlet side passage of the mixing nozzle, the fluid introduction hole, and the vortex and turbulent flow of the fluid near the opening. However, when the thread tension is lowered, the running of the thread in the entrance side passage becomes worse.
排出される流体により不安定になり、開繊斑が生じて混
合斑が惹起されるためである。This is because the discharged fluid makes it unstable, causing opening spots and mixing spots.
それ故供給系路の傾き角度αは糸通路内での糸条が安定
して走行できるところの２０°以上６０゜以１の角度に
すべきである。Therefore, the inclination angle α of the supply path should be between 20° and 60°, which allows the yarn to run stably in the yarn path.
該角度が２０°より小さいときは、殆んど傾けた効果が
表われず排出流体により糸条の走行は安定しなかった。When the angle was smaller than 20°, almost no effect of tilting was exhibited, and the running of the yarn was not stable due to the discharged fluid.
逆に６０°よりも大きくすると、糸条と糸通路入口部で
の接触が強くなり糸通路内の糸条張力が上昇したり糸条
がしごかれて張力変動が生ずる。On the other hand, if the angle is larger than 60°, the contact between the yarn and the yarn passage entrance becomes strong, and the yarn tension in the yarn passage increases or the yarn is squeezed, causing tension fluctuations.
従って供給系路の角度αは２０°以上６０°以下にすべ
きであり ％に２０°以上５０°以下の範囲が好ましい
。Therefore, the angle α of the supply path should be between 20° and 60°, preferably between 20° and 50°.
この関係を図示したのが第４図で１図においてＢの曲線
が角度α（０）と混合度との関係を Ｂ／の曲線が角度
α（０）と混合度斑との関係を示す。This relationship is illustrated in FIG. 4. In FIG. 1, the curve B shows the relationship between the angle α(0) and the degree of mixing, and the curve B/ shows the relationship between the angle α(0) and the degree of mixing.

２図８′の位置に設けてもよいし傾けずに糸通路の中心
線に一致させてもよい。Next, the angle β of the lead-out yarn path on the yarn outlet side does not have a large effect on the mixing effect, and for maintenance management purposes, it may be set at the same inclination angle as the inlet side at the position shown in Fig. 2 8', or it may be set at the position shown in Fig. It may be aligned with the center line.
尚、糸条の傾き方向はいずれでもかまわないが。Note that the direction of inclination of the threads may be any direction.
流体導入孔の軸を含む面内が好ましいようである。It seems preferable to be in a plane that includes the axis of the fluid introduction hole.
