Description
本発明は、紡績機に備えられる空気紡績装置に関し、詳しくは、ドラフト装置から送られてきた繊維束に対し、紡績ノズル部材によって生成された旋回気流を作用させて、当該繊維束から繊維を分離させると共に、中空ガイド軸体の先端部の周りに当該繊維を振り回しつつ撚り込んで紡績糸とする空気紡績装置に関する。 The present invention relates to an air spinning device provided in a spinning machine, and more specifically, a swirl airflow generated by a spinning nozzle member is applied to a fiber bundle sent from a draft device to separate fibers from the fiber bundle. In addition, the present invention relates to an air spinning device that twists a fiber around a tip portion of a hollow guide shaft body and twists the fiber to make a spun yarn.
従来、ドラフト装置から送られてきた繊維束から紡績糸を製造する紡績装置として、種々の紡績装置が存在している。近年では、旋回気流を生じさせる紡績ノズル部材と中空ガイド軸体とを備えていて、高速で紡績することができる空気紡績装置が知られている（例えば、特許文献１参照）。 Conventionally, there are various spinning devices as spinning devices for producing spun yarn from a fiber bundle sent from a draft device. In recent years, there has been known an air spinning apparatus that includes a spinning nozzle member that generates a swirling airflow and a hollow guide shaft body and that can perform spinning at high speed (for example, see Patent Document 1).
空気紡績装置は主に、図６に示す如く、ノズル孔２１ｂおよび紡績室２１ａを備えた紡績ノズル部材２１と、紡績室２１ａに繊維束Ｆを案内するニードル２１ｅと、軸方向に延びる糸通路２２ｄを有していて、紡績室２１ａにおいてノズル孔２１ｂに対向するように配置された中空ガイド軸体２２と、から構成されている。 As shown in FIG. 6, the pneumatic spinning device mainly includes a spinning nozzle member 21 having a nozzle hole 21b and a spinning chamber 21a, a needle 21e for guiding the fiber bundle F to the spinning chamber 21a, and a yarn passage 22d extending in the axial direction. And a hollow guide shaft body 22 disposed so as to face the nozzle hole 21b in the spinning chamber 21a.
上記の空気紡績装置では、ドラフト装置から送出された繊維束Ｆは、ニードル２１ｅによって案内されつつ、紡績室２１ａに導入される。紡績室２１ａに導入された繊維束Ｆは、ノズル孔２１ｂから圧縮空気が噴出されることにより発生する旋回気流の作用により、中心繊維ｆ１に対して鞘繊維ｆ２が分離されながら、中空ガイド軸体２２の糸通路２２ｄ内に導入されていく。この際、鞘繊維ｆ２は、その後端側（未だ糸通路２２ｄ内に導入されていない部分）が、旋回気流の作用を受けて、中空ガイド軸体２２の先端部の周囲で振り回されながら、糸通路２２ｄ内へ導入されていく。その結果、中心繊維ｆ１の周囲に鞘繊維ｆ２が巻き付き、実撚り状の紡績糸Ｙが製造されることになる。
ところで、上記の空気紡績装置を用いて、ポリエステル等の合成繊維を紡績する場合が当然ある。合成繊維は一般に、その製造工程において、繊維同士による引抜き抵抗を下げる等の目的のために、合成繊維用油剤が付与されている。 Incidentally, there are naturally cases where synthetic fibers such as polyester are spun using the pneumatic spinning device. Synthetic fibers are generally provided with an oil for synthetic fibers in the production process for the purpose of reducing the pulling resistance between the fibers.
上記の空気紡績装置によって合成繊維を紡績する場合、その鞘繊維ｆ２が中空ガイド軸体２２の先端部の周囲で振り回される際に、合成繊維用油剤が当該先端部の外周面に付着し、縞状に堆積していくことがあった（図７参照）。この場合、その堆積物が阻害要因となり、鞘繊維ｆ２が中空ガイド軸体２２の周りで十分に振り回されなくなって、糸の強力が弱い所謂弱糸が製造されてしまう問題があった。 When the synthetic fiber is spun by the above-described pneumatic spinning device, when the sheath fiber f2 is swung around the distal end portion of the hollow guide shaft body 22, the synthetic fiber oil adheres to the outer peripheral surface of the distal end portion, and stripes (See FIG. 7). In this case, there is a problem that the deposit becomes an obstructing factor, and the sheath fiber f2 is not sufficiently swung around the hollow guide shaft body 22, so that a so-called weak yarn having weak yarn strength is produced.
また、弱糸の発生を防止するには、一定時間毎に作業者が上記堆積物を布で拭い去る必要が生じ、非常に煩雑であると共に、生産効率の低下を招いていた。 Further, in order to prevent the occurrence of weak yarn, it is necessary for the operator to wipe off the deposit with a cloth every predetermined time, which is very complicated and causes a reduction in production efficiency.
本発明は上記事情に鑑みてなされたものであり、その目的とするところは、紡績糸の原料に含まれる油剤が中空ガイド軸体の先端部外周面に堆積するのを防止することができる空気紡績装置を提供することにある。 The present invention has been made in view of the above circumstances, and an object of the present invention is to prevent the oil contained in the raw material of the spun yarn from accumulating on the outer peripheral surface of the distal end portion of the hollow guide shaft body. It is to provide a spinning device.

紡績ノズル部材２１は、図３に示す如く、繊維束Ｆが通過する紡績室２１ａと、紡績室２１ａ内に圧縮空気を噴出して旋回気流を発生させるべく、紡績室２１ａに接線方向から接続された複数の第１ノズル孔２１ｂとを備えている。 As shown in FIG. 3, the spinning nozzle member 21 is connected to the spinning chamber 21a through which the fiber bundle F passes and the spinning chamber 21a from the tangential direction so as to generate a swirling airflow by jetting compressed air into the spinning chamber 21a. And a plurality of first nozzle holes 21b.
第１ノズル孔２１ｂは、繊維束Ｆの通過方向に向かって傾斜している一方、第１圧縮空気通路２１ｃを介して、圧縮空気源２３に接続されている。 The first nozzle hole 21b is inclined toward the passing direction of the fiber bundle F, and is connected to the compressed air source 23 via the first compressed air passage 21c.
圧縮空気源２３と第１圧縮空気通路２１ｃとを結ぶ圧縮空気ラインの途中に、界面活性剤付与器２４が配置されており、第１ノズル孔２１ｂから噴出される圧縮空気中に、界面活性剤をミスト状に混入するようになっている。 A surfactant applicator 24 is disposed in the middle of the compressed air line connecting the compressed air source 23 and the first compressed air passage 21c, and the surfactant is contained in the compressed air ejected from the first nozzle hole 21b. Is mixed in mist form.
界面活性剤付与器２４は、図４に示す如く、圧縮空気源２３からの圧縮空気が通過する第１通路２４ａと、第１通路２４ａの下方に設けられ、界面活性剤Ｓを貯留する貯留室２４ｂと、第１通路２４ａと貯留室２４ｂとを繋ぐ第２通路２４ｃと、第１通路２４ａの上方に設けられた滴下室２４ｄと、貯留室２４ｂから滴下室２４ｄまで延びて、滴下室２４ｄに界面活性剤Ｓを滴下する滴下管２４ｅと、第２通路２４ｃよりも下流側に設けられ、滴下室２４ｄと第１通路２４ａとを繋ぐ滴下通路２４ｆと、から構成されている。 As shown in FIG. 4, the surfactant applicator 24 is provided with a first passage 24 a through which compressed air from the compressed air source 23 passes, and a storage chamber in which the surfactant S is stored below the first passage 24 a. 24b, a second passage 24c connecting the first passage 24a and the storage chamber 24b, a dropping chamber 24d provided above the first passage 24a, and extending from the storage chamber 24b to the dropping chamber 24d, into the dropping chamber 24d. A dropping tube 24e for dropping the surfactant S and a dropping passage 24f provided downstream of the second passage 24c and connecting the dropping chamber 24d and the first passage 24a are configured.

界面活性剤付与器２４では、ＩＮ側から入った空気の一部が第２通路２４ｃを経て貯留室２４ｂ内の界面活性剤Ｓの液面を加圧し、他の空気はそのまま第１通路２４ａを通過する（図４の実線矢印参照）。このとき、貯留室２４ｂと滴下室２４ｄとの間に圧力差が生じるため、界面活性剤Ｓは滴下管２４ｅを介して滴下室２４ｄに滴下される。滴下された界面活性剤Ｓは、滴下通路２４ｆから第１通路２４ａを通過する空気に対してミスト状に混入される（図４の破線矢印参照）。 In the surfactant applicator 24, a part of the air entering from the IN side pressurizes the liquid level of the surfactant S in the storage chamber 24b through the second passage 24c, and other air passes through the first passage 24a as it is. Pass (see solid arrow in FIG. 4). At this time, since a pressure difference is generated between the storage chamber 24b and the dropping chamber 24d, the surfactant S is dropped into the dropping chamber 24d through the dropping tube 24e. The dropped surfactant S is mixed in a mist form with respect to the air passing through the first passage 24a from the dropping passage 24f (see the broken line arrow in FIG. 4).
また、紡績ノズル部材２１は、図３に示す如く、紡績室２１ａの上流側に、紡績室２１ａに通じる案内孔２１ｄと、案内孔２１ｄ内に配置されていて、紡績室２１ａ内に突出し、後述する糸通路２２ｄの入口に対向するニードル２１ｅとを有している。 Further, as shown in FIG. 3, the spinning nozzle member 21 is disposed on the upstream side of the spinning chamber 21a, in a guide hole 21d communicating with the spinning chamber 21a, in the guide hole 21d, and protrudes into the spinning chamber 21a. And a needle 21e facing the inlet of the yarn passage 22d.
紡績ノズル部材２１はさらに、紡績室２１ａから下流側に向かって延びるテーパ孔２１ｆと、テーパ孔２１ｆに通じると共に、繊維束Ｆの通過方向に対して略直交する一方向に開放された排出室２１ｇと、排出室２１ｇに通じると共に中空ガイド軸体２２と嵌合する嵌合孔２１ｈと、を有している。 The spinning nozzle member 21 further has a tapered hole 21f extending from the spinning chamber 21a toward the downstream side, and communicates with the tapered hole 21f. The discharge chamber 21g is opened in one direction substantially orthogonal to the passing direction of the fiber bundle F. And a fitting hole 21h that communicates with the discharge chamber 21g and fits with the hollow guide shaft body 22.

なお、外部筒体２２ａの先端部分のテーパ形状は、紡績ノズル部材２１のテーパ孔２１ｆと略等しいテーパ角になっていると共に、テーパ孔２１ｆとの間に隙間が生じるように形成されている。

また、中空ガイド軸体２２は、外部筒体２２ａおよび内部筒体２２ｂを貫通して軸方向に延びる糸通路２２ｄを有しており、紡績ノズル部材２１によって紡績された紡績糸Ｙが通過するようになっている。 The hollow guide shaft body 22 has a yarn passage 22d that extends in the axial direction through the outer cylinder body 22a and the inner cylinder body 22b, so that the spun yarn Y spun by the spinning nozzle member 21 passes therethrough.

Here, the second nozzle hole 22e is formed so as to generate a swirling airflow opposite to the swirling airflow generated by the first nozzle hole 21b in the spinning nozzle member 21.
糸送り装置３は、図２に示す如く、紡績機Ｓｐの機枠に支持されたデリベリローラ３１と、デリベリローラ３１に接離自在に設けられたニップローラ３２とから構成されており、空気紡績装置２によって生成された紡績糸Ｙを、デリベリローラ３１とニップローラ３２との間に挟みつつデリベリローラ３１を回転駆動させることにより、巻取装置４側へ送るようになっている。 As shown in FIG. 2, the yarn feeding device 3 includes a delivery roller 31 supported by a machine frame of the spinning machine Sp, and a nip roller 32 provided so as to be able to contact with and separate from the delivery roller 31.

次に、本実施形態に係る紡績機Ｓｐの動作について説明する。
通常の紡績状態では、第２ノズル孔２２ｅは圧縮空気を噴射しない非作動状態とされ、第１ノズル孔２１ｂのみ圧縮空気を噴射する作動状態とされる。このとき、紡績室２１ａには旋回気流が発生し、テーパ孔２１ｆを螺旋状に流れながら排出室２１ｇから排出される。
Next, the operation of the spinning machine Sp according to this embodiment will be described.
In a normal spinning state, the second nozzle hole 22e is in a non-operating state in which compressed air is not injected, and only the first nozzle hole 21b is in an operating state in which compressed air is injected. At this time, a swirling airflow is generated in the spinning chamber 21a and is discharged from the discharge chamber 21g while flowing spirally through the tapered hole 21f.
繊維束Ｆは、フロントローラ１ｄから案内孔２１ｄ、紡績室２１ａ、糸通路２２ｄを通過して糸送り装置３に至る連続状態にあり、糸送り装置３により下流側への送り力が付与されることによって、糸には張力が付与されている。 The fiber bundle F is in a continuous state from the front roller 1d through the guide hole 21d, the spinning chamber 21a, and the yarn passage 22d to reach the yarn feeding device 3, and a feeding force to the downstream side is given by the yarn feeding device 3. Thus, tension is applied to the yarn.
ドラフト装置１のフロントローラ１ｄから送り出された繊維束Ｆは、紡績ノズル部材２１の案内孔２１ｄを通過して紡績室２１ａに入り、第１ノズル孔２１ｂによる旋回気流の作用を受ける。ここで、第１ノズル孔２１ｂによる旋回気流は、界面活性剤付与器２４を通過した圧縮空気によって形成されているため、ミスト状の界面活性剤を含んでいる。 The fiber bundle F sent out from the front roller 1d of the draft device 1 passes through the guide hole 21d of the spinning nozzle member 21 and enters the spinning chamber 21a, and receives the action of the swirling airflow by the first nozzle hole 21b. Here, since the swirling airflow by the first nozzle hole 21b is formed by the compressed air that has passed through the surfactant applicator 24, it contains a mist-like surfactant.
繊維束Ｆは、この旋回気流の作用によって中心繊維に対して鞘繊維が分離されながら、中空ガイド軸体２２の糸通路２２ｄ内に導入されていく。この際、鞘繊維は、その後端側（未だ糸通路２２ｄ内に導入されていない部分）が、旋回気流の作用を受けて、中空ガイド軸体２２先端のテーパ形状部の周囲で振り回されながら、糸通路２２ｄ内へ導入されていく。その結果、中心繊維の周囲に鞘繊維が巻き付き、実撚り状の紡績糸Ｙが製造される。
なお、この撚りは、フロントローラ１ｄ側へ伝播しようとするが、ニードル２１ｅによって阻止される。すなわち、ニードル２１ｅは、撚り伝播防止手段となっている。
The fiber bundle F is introduced into the yarn passage 22d of the hollow guide shaft body 22 while the sheath fiber is separated from the center fiber by the action of the swirling airflow. At this time, the sheath fiber is swung around the taper-shaped portion at the tip of the hollow guide shaft 22 under the effect of the swirling airflow at the rear end side (the portion not yet introduced into the yarn passage 22d) It is introduced into the yarn passage 22d. As a result, the sheath fiber is wound around the center fiber, and a real twisted spun yarn Y is manufactured.
Although this twist tends to propagate to the front roller 1d side, it is blocked by the needle 21e. That is, the needle 21e is a twist propagation preventing means.
上記のように製造された紡績糸Ｙは、糸通路２２ｄを通過した後、糸送り装置３を介して巻取装置４に送られ、パッケージＰとして巻き取られる。 The spun yarn Y manufactured as described above passes through the yarn passage 22d, is then sent to the winding device 4 through the yarn feeding device 3, and is wound as a package P.
なお、始動時または糸切れ発生時は、糸継台車Ｐおよび第２ノズル孔２２ｅが作動して糸継ぎ作業が実行される。この糸継ぎ作業は公知であるため（例えば、特開２００１−７３２３５号公報参照）、詳細な説明は省略するが、糸送り装置３による送り力の代わりに、第２ノズル孔２２ｅによって糸通路２２ｄ内に旋回気流を発生させることで糸通路２２ｄの入口に負圧を発生させ、紡績室２１ａの繊維束Ｆを糸通路２２ｄ内に引き込んで下流側に送るようになっている。 At the time of start-up or when a yarn breakage occurs, the yarn splicing carriage P and the second nozzle hole 22e are operated to execute the yarn splicing operation. Since this yarn splicing operation is known (for example, refer to Japanese Patent Laid-Open No. 2001-73235), detailed description is omitted, but instead of the feeding force by the yarn feeding device 3, the yarn passage 22d is formed by the second nozzle hole 22e. By generating a swirling air flow in the inside, a negative pressure is generated at the inlet of the yarn passage 22d, and the fiber bundle F in the spinning chamber 21a is drawn into the yarn passage 22d and sent to the downstream side.
上記の空気紡績装置２によれば、第１ノズル孔２１ｂから噴出する圧縮空気によって発生した旋回気流の作用によって、中心繊維に対して鞘繊維を分離し、その鞘繊維を中空ガイド軸体２２ａ先端のテーパ形状部の周りで振り回しながら加撚し、実撚り状の紡績糸Ｙを高速で製造することができる。 According to the pneumatic spinning device 2 described above, the sheath fiber is separated from the center fiber by the action of the swirling airflow generated by the compressed air ejected from the first nozzle hole 21b, and the sheath fiber is separated from the tip of the hollow guide shaft body 22a. It is possible to produce an actual twisted spun yarn Y at a high speed by twisting it around the taper-shaped portion.
第１ノズル孔２１ｂによる旋回気流は、界面活性剤付与器２４から付与されたミスト状の界面活性剤を含んでいるため、特に中空ガイド軸体２２の外部筒体２２ｂの先端部外周面に当該界面活性剤が作用せしめられる。これにより、空気紡績装置２は、合成繊維等の油剤を含有する原料を用いて紡績する際に上記先端部外周面に堆積する当該油剤を除去することができる。したがって、油剤の堆積に起因する加撚力の低下を防止し、弱糸の発生を回避することができる。 The swirling airflow generated by the first nozzle hole 21b includes the mist-like surfactant applied from the surfactant applicator 24. Therefore, the swirling airflow particularly affects the outer peripheral surface of the distal end portion of the outer cylindrical body 22b of the hollow guide shaft body 22. A surfactant is allowed to act. Thereby, the air spinning device 2 can remove the oil agent deposited on the outer peripheral surface of the tip when spinning using a raw material containing an oil agent such as synthetic fiber. Accordingly, it is possible to prevent the twisting force from being reduced due to the accumulation of the oil agent and to avoid the generation of weak yarn.
また、界面活性剤付与器２４には、ルブリケータ等の公知の器具を転用することができると共に、その設置も、圧縮空気源２３から第１ノズル孔２１ｂまでの圧縮空気ラインの途中に配置するだけでよく、シンプルかつ低コストに構成することができる。 Further, a known device such as a lubricator can be diverted to the surfactant applicator 24, and its installation is also arranged in the middle of the compressed air line from the compressed air source 23 to the first nozzle hole 21b. It can be configured simply and at low cost.
以上、本発明の実施の形態について具体的に説明したが、本発明はこれらに限定されるものではない。
図５Ａに示す如く、圧縮空気源２３から界面活性剤付与器２４を介して空気紡績装置２の紡績ノズル部材２１へ到るラインに対してバイパスラインＢＬを設け、制御器２６で制御可能な三方電磁弁２５によって両ラインを切替え可能に構成してもよい。この場合、制御器２６に所定のスケジュールを予め設定しておくことで、紡績ノズル部材２１の紡績室２１ａにおいて発生する旋回気流への界面活性剤の混入を間欠的、計画的に行うことができる。これによって、界面活性剤の混入を適切に制御し、その消費量を最適化することもできる。
As mentioned above, although embodiment of this invention was described concretely, this invention is not limited to these.
As shown in FIG. 5A, a bypass line BL is provided for the line from the compressed air source 23 to the spinning nozzle member 21 of the pneumatic spinning device 2 through the surfactant applicator 24, and three directions that can be controlled by the controller 26 You may comprise so that both lines can be switched by the solenoid valve 25. FIG. In this case, by setting a predetermined schedule in the controller 26 in advance, mixing of the surfactant into the swirling airflow generated in the spinning chamber 21a of the spinning nozzle member 21 can be performed intermittently and systematically. . Thereby, the mixing of the surfactant can be appropriately controlled and the consumption amount can be optimized.
さらに、図５Ｂに示す如く、油剤の堆積状況に応じて変化する信号（例えば、中空ガイド軸体２２先端のテーパ形状部表面における所定箇所の温度、圧力等を測定することにより得られる信号、当該所定箇所に対して設けられた光電センサにより得られる光量の変化に基づく信号、あるいは紡績糸Ｙの強力を測定して得られる信号等）を上記制御器２６に送り、その信号に基づいて、上記両ラインの切替えを行うように構成してもよい。この場合、通常時はバイパスラインＢＬを用い、上記信号に基づき油剤が堆積していると判断されたときのみ、界面活性剤付与器２４を通過するラインを用いることができる。これにより、旋回気流への界面活性剤の付与を、より適切に制御することができる。 Furthermore, as shown in FIG. 5B, a signal that changes according to the accumulation state of the oil (for example, a signal obtained by measuring the temperature, pressure, etc. at a predetermined location on the surface of the tapered portion at the tip of the hollow guide shaft 22, A signal based on a change in the amount of light obtained by a photoelectric sensor provided for a predetermined location or a signal obtained by measuring the strength of the spun yarn Y) is sent to the controller 26, and based on the signal, the above-mentioned You may comprise so that both lines may be switched. In this case, the bypass line BL is normally used, and a line passing through the surfactant applicator 24 can be used only when it is determined that the oil is deposited based on the signal. Thereby, the provision of the surfactant to the swirling airflow can be controlled more appropriately.
なお、界面活性剤付与器２４の滴下管２４ｅの管路内に対して出没可能なニードル弁を設け、その出没量を制御器によって制御するように構成することで、界面活性剤の混入を制御してもよい。 It should be noted that a needle valve that can be moved into and out of the pipe of the dripping pipe 24e of the surfactant applicator 24 is provided, and the amount of the protruding and protruding is controlled by the controller, thereby controlling the mixing of the surfactant. May be.
なお、上記の実施形態においては、中空ガイド軸体が回転しないタイプの空気紡績装置について説明したが、中空ガイド軸体が回転するタイプの空気紡績装置（例えば、特開平６−１７３１２９号公報参照）であっても、同様に構成することができる。 In the above embodiment, the pneumatic spinning device in which the hollow guide shaft body does not rotate has been described. However, the pneumatic spinning device in which the hollow guide shaft body rotates (see, for example, JP-A-6-173129). Even so, it can be configured similarly.
