Description

本発明は、合繊糸用スプライサに関する。 The present invention relates to a splicer for synthetic yarn.

従来の合繊糸用スプライサとして、例えば、特許文献１に記載されているものが知られている。特許文献１に記載の合繊糸用スプライサは、２本の合繊糸の始端と終端とを逆方向に引き揃えてエアノズル内に引き込み、引き込んだ糸端のエアノズル外の両側部分を押さえ、押さえた両側部分をエアノズル内の方向に移動させることにより引き揃えた糸端に、エアノズル内で弛みを持たせ、エアノズル内の空気流により糸継ぎを行う。 As a conventional splicer for synthetic fiber yarn, for example, the one described in Patent Document 1 is known. The splicer for synthetic yarn described in Patent Document 1 aligns the start end and the end of two synthetic yarns in opposite directions and draws them into an air nozzle, and presses and presses both side portions of the drawn yarn ends outside the air nozzle. The yarn ends that are aligned by moving the portion toward the inside of the air nozzle are provided with slack in the air nozzle, and the yarn is spliced by the air flow in the air nozzle.

特開平１０－１７２１４号公報Japanese Unexamined Patent Publication No. 10-17214

合繊糸用スプライサは、例えば、合成繊維を巻き取る糸巻取機において、一の供給ボビンの糸の終端と他の供給ボビンの糸の始端とを糸継ぎするために使用される。糸巻取機では、糸にテンションを与えつつ糸をボビンに巻き取り、パッケージを形成する。そのため、合繊糸用スプライサによって糸継ぎされた糸同士の絡合部は、テンションが加わると引っ張られる。糸巻取機では、糸の巻き取り中に絡合部が解けると、巻取動作を一時停止して作業を行わなければならないため、生産効率が低下する。そのため、合繊糸用スプライサには、巻取テンションに耐え得る引張伸度を有する絡合部を形成することが求められる。 The synthetic fiber splicer is used, for example, in a yarn winder for winding synthetic fibers to join the end of the yarn of one feed bobbin and the start of the yarn of another feed bobbin. In the thread winder, the thread is wound on the bobbin while applying tension to the thread to form a package. Therefore, the entangled portion between the yarns spliced by the synthetic fiber splicer is pulled when tension is applied. In the thread winder, if the entangled portion is unwound during the winding of the thread, the winding operation must be temporarily stopped to perform the work, which lowers the production efficiency. Therefore, the synthetic fiber splicer is required to form an entangled portion having a tensile elongation that can withstand the take-up tension.

本発明の一側面は、絡合部の引張伸度の低下を抑制できる合繊糸用スプライサを提供することを目的とする。 One aspect of the present invention is to provide a splicer for synthetic yarns capable of suppressing a decrease in tensile elongation of an entangled portion.

本発明の一側面に係る合繊糸用スプライサは、合成繊維からなる一方の糸と他方の糸との糸継ぎを行う合繊糸用スプライサであって、一方の糸及び他方の糸が挿通可能である空間を形成する通路と、通路に開口すると共に流体を噴射する噴射孔と、を有する糸継部と、糸継部の通路を挟む位置に設けられ、空間に挿通される一方の糸及び他方の糸のそれぞれを挟持する一対の挟持機構と、を備え、一対の挟持機構のそれぞれは、一方の糸及び他方の糸のそれぞれを挟持する挟持部と、挟持部を支持する支持部と、を有し、支持部は、一対の挟持機構の対向方向において、挟持部を挟む位置に配置されている第１当接面及び第２当接面をそれぞれ有し、第２当接面は、糸継部と挟持部との間に配置されており、第１当接面よりも上方に位置している。 The synthetic fiber splicer according to one aspect of the present invention is a synthetic fiber splicer that joins one thread made of synthetic fibers and the other thread, and one thread and the other thread can be inserted through the splicer. A thread splicing portion having a passage forming a space and an injection hole for injecting fluid while opening in the passage, and one thread and the other thread provided at a position sandwiching the passage of the thread splicing portion and inserted into the space. Each of the pair of pinching mechanisms comprises a pair of pinching mechanisms for pinching each of the threads of the thread, and each of the pair of pinching mechanisms has a pinching portion for sandwiching one thread and each of the other threads, and a supporting portion for supporting the pinching portion. The support portion has a first contact surface and a second contact surface arranged at positions sandwiching the sandwiching portion in the opposite direction of the pair of sandwiching mechanisms, and the second contact surface is a thread. It is arranged between the joint portion and the sandwiching portion, and is located above the first contact surface.

本発明の一側面に係る合繊糸用スプライサでは、合成繊維からなる一方の糸及び他方の糸は、挟持部を固定点として通路内で振り回される。合繊糸用スプライサでは、第２当接面は、糸継部と挟持部との間に配置されており、第１当接面よりも上方に位置している。この構成では、一方の糸及び他方の糸が配置されたときに、一方の糸及び他方の糸の自重によって、一方の糸及び他方の糸が少なくとも第２当接面に当接する。この状態において、一方の糸及び他方の糸が挟持部によって挟持され、一方の糸及び他方の糸に流体が噴射されると、一方の糸及び他方の糸は、実質的には、第２当接面を固定点として振り回される。そのため、合繊糸用スプライサでは、振り回される一方の糸及び他方の糸において、支持部との接触による摩擦が生じ難い。したがって、合繊糸用スプライサでは、絡合部を適切に形成できる。その結果、合繊糸用スプライサでは、絡合部の引張伸度の低下を抑制できる。 In the synthetic fiber splicer according to one aspect of the present invention, one thread made of synthetic fibers and the other thread are swung in the passage with the sandwiching portion as a fixed point. In the synthetic fiber splicer, the second contact surface is arranged between the yarn joint portion and the sandwiching portion, and is located above the first contact surface. In this configuration, when one thread and the other thread are arranged, the weight of one thread and the other thread causes one thread and the other thread to come into contact with at least the second contact surface. In this state, when one thread and the other thread are sandwiched by the sandwiching portion and the fluid is sprayed onto the one thread and the other thread, the one thread and the other thread are substantially the second thread. It is swung around with the contact surface as a fixed point. Therefore, in the splicer for synthetic fiber yarn, friction due to contact with the support portion is unlikely to occur in one yarn and the other yarn that are swung around. Therefore, in the splicer for synthetic fiber yarn, the entangled portion can be appropriately formed. As a result, in the splicer for synthetic yarn, it is possible to suppress a decrease in the tensile elongation of the entangled portion.

一実施形態においては、挟持部は、互いに対向する一対の挟持部材を有し、第１当接面及び第２当接面は、一方の挟持部材と他方の挟持部材とが当接する位置に設けられていてもよい。この構成では、一対の挟持部材よって挟持される一方の糸及び他方の糸を、第２当接面に確実に当接させることができる。そのため、一方の糸及び他方の糸は、確実に第２当接面を固定点として振り回される。したがって、振り回される一方の糸及び他方の糸において、支持部との接触による摩擦が生じない。その結果、合繊糸用スプライサでは、絡合部を適切に形成でき、絡合部の引張伸度の低下を抑制できる。 In one embodiment, the sandwiching portion has a pair of sandwiching members facing each other, and the first contact surface and the second contact surface are provided at positions where one sandwiching member and the other sandwiching member abut. It may have been. In this configuration, one thread and the other thread sandwiched by the pair of sandwiching members can be reliably brought into contact with the second contact surface. Therefore, one thread and the other thread are surely swung around the second contact surface as a fixed point. Therefore, in one thread and the other thread that are swung, friction due to contact with the support portion does not occur. As a result, in the splicer for synthetic fiber yarn, the entangled portion can be appropriately formed, and the decrease in the tensile elongation of the entangled portion can be suppressed.

一実施形態においては、第２当接面は、一対の挟持機構の対向方向に沿って延在する平坦面であってもよい。この構成では、振り回される一方の糸及び他方の糸において、支持部との接触による摩擦をより一層回避できる。 In one embodiment, the second contact surface may be a flat surface extending along the opposite direction of the pair of sandwiching mechanisms. In this configuration, friction due to contact with the support portion can be further avoided in one thread and the other thread that are swung around.

一実施形態においては、第１当接面及び第２当接面に直交する方向における第１当接面と第２当接面との間の寸法が、０．５ｍｍ以上１．５ｍｍ以下であってもよい。この構成では、一方の糸及び他方の糸をより確実に第２当接面に当接させることができる。 In one embodiment, the dimension between the first contact surface and the second contact surface in the direction orthogonal to the first contact surface and the second contact surface is 0.5 mm or more and 1.5 mm or less. You may. In this configuration, one thread and the other thread can be more reliably brought into contact with the second contact surface.

本発明の一側面によれば、絡合部の引張伸度の低下を抑制できる。 According to one aspect of the present invention, it is possible to suppress a decrease in the tensile elongation of the entangled portion.

The second contact surface 27c is located above the first contact surface 27b. The term "upper" as used herein means a direction orthogonal to the facing direction between the first pinching mechanism 20 and the second pinching mechanism 30 and the facing direction (pinching direction) between the first pinching member 24 and the second pinching member 26, which will be described later. On the side where the first yarn Y1 and the second yarn Y2 are introduced. That is, it shows the upper side in the vertical direction shown in FIG. The first contact surface 27b is located closer to the main surface 22b than the second contact surface 27c. The second contact surface 27c is located closer to the main surface 22a than the first contact surface 27b.

第１当接面２７ｂと主面２２ｂとの間の距離Ｄ１は、第２当接面２７ｃと主面２２ｂとの間の距離Ｄ２よりも短い。言い換えれば、第２当接面２７ｃと主面２２ｂとの間の距離Ｄ２は、第１当接面２７ｂと主面２２ｂとの間の距離Ｄ１よりも長い。見方を変えると、第１当接面２７ｂと主面２２ａとの間の距離は、第２当接面２７ｃと主面２２ａとの間の距離よりも長い。言い換えれば、第２当接面２７ｃと主面２２ａとの間の距離は、第１当接面２７ｂと主面２２ａとの間の距離よりも短い。 The distance D1 between the first contact surface 27b and the main surface 22b is shorter than the distance D2 between the second contact surface 27c and the main surface 22b. In other words, the distance D2 between the second contact surface 27c and the main surface 22b is longer than the distance D1 between the first contact surface 27b and the main surface 22b. From a different point of view, the distance between the first contact surface 27b and the main surface 22a is longer than the distance between the second contact surface 27c and the main surface 22a.

The difference G is a dimension between the first contact surface 27b and the second contact surface 27c in the direction orthogonal to the first contact surface 27b and the second contact surface 27c. The difference G may be appropriately set according to the diameters of the first sandwiching member 24 and the second sandwiching member 26. For example, if the distance D1 between the first contact surface 27b and the main surface 22b is shortened and the difference G is increased, the first thread Y1 sandwiched between the first sandwiching member 24 and the second sandwiching member 26 and The length of the second thread Y2 may be shortened. When the lengths of the first thread Y1 and the second thread Y2 sandwiched between the first sandwiching member 24 and the second sandwiching member 26 become shorter, the first thread Y1 and the second thread Y2 are stably held in the sandwiching portion 23. It may not be possible to pinch it. Therefore, it is preferable that the difference G is appropriately set based on an experiment or the like so that the first thread Y1 and the second thread Y2 can be stably sandwiched by the sandwiching portion 23.

第２当接面２７ｃと側面２２ｄとは、略９０°の角度を成している。第２当接面２７ｃと側面２２ｄとにより形成される角の頂部は、表面研磨されていることが好ましい。この構成では、第１糸Ｙ１及び第２糸Ｙ２が上記頂部から離間するときにおいて、第１糸Ｙ１及び第２糸Ｙ２がダメージを受けることを抑制できる。 The second contact surface 27c and the side surface 22d form an angle of approximately 90 °. The top of the corner formed by the second contact surface 27c and the side surface 22d is preferably surface-polished. In this configuration, it is possible to prevent the first thread Y1 and the second thread Y2 from being damaged when the first thread Y1 and the second thread Y2 are separated from the top.

第１当接面３７ｂと主面３２ｂとの間の距離Ｄ１は、第２当接面３７ｃと主面３２ｂとの間の距離Ｄ２よりも短い。言い換えれば、第２当接面３７ｃと主面３２ｂとの間の距離Ｄ２は、第１当接面３７ｂと主面３２ｂとの間の距離Ｄ１よりも長い。見方を変えると、第１当接面３７ｂと主面３２ａとの間の距離は、第２当接面３７ｃと主面３２ａとの間の距離よりも長い。言い換えれば、第２当接面３７ｃと主面３２ａとの間の距離は、第１当接面３７ｂと主面３２ａとの間の距離よりも短い。第１当接面３７ｂは、第１挟持機構２０の第１当接面２７ｂと同じ位置であり、第２当接面３７ｃは、第１挟持機構２０の第２当接面２７ｃと同じ位置である。 The distance D1 between the first contact surface 37b and the main surface 32b is shorter than the distance D2 between the second contact surface 37c and the main surface 32b. In other words, the distance D2 between the second contact surface 37c and the main surface 32b is longer than the distance D1 between the first contact surface 37b and the main surface 32b. From a different point of view, the distance between the first contact surface 37b and the main surface 32a is longer than the distance between the second contact surface 37c and the main surface 32a. In other words, the distance between the second contact surface 37c and the main surface 32a is shorter than the distance between the first contact surface 37b and the main surface 32a. The first contact surface 37b is at the same position as the first contact surface 27b of the first holding mechanism 20, and the second contact surface 37c is at the same position as the second contact surface 27c of the first holding mechanism 20. be.

The difference G may be appropriately set according to the diameters of the first sandwiching member 34 and the second sandwiching member 36 and the like.

第２当接面３７ｃと側面３２ｄとは、略９０°の角度を成している。第２当接面３７ｃと側面３２ｄとにより形成される角の頂部は、表面研磨されていることが好ましい。 The second contact surface 37c and the side surface 32d form an angle of approximately 90 °. The top of the corner formed by the second contact surface 37c and the side surface 32d is preferably surface-polished.

図２に示されるように、挟持部３３は、第１挟持部材３４と、第２挟持部材３６と、を有している。第１挟持部材３４及び第２挟持部材３６のそれぞれは、円柱状を呈している。第１挟持部材３４及び第２挟持部材３６のそれぞれは、例えば、耐摩耗性を有するＳＵＳ等の金属で形成されている。第１挟持部材３４及び第２挟持部材３６のそれぞれの直径は、適宜設定されればよい。 As shown in FIG. 2, the sandwiching portion 33 has a first sandwiching member 34 and a second sandwiching member 36. Each of the first sandwiching member 34 and the second sandwiching member 36 has a columnar shape. Each of the first holding member 34 and the second holding member 36 is made of, for example, a metal such as SUS having wear resistance. The diameters of the first holding member 34 and the second holding member 36 may be appropriately set.

第１挟持部材３４及び第２挟持部材３６は、支持部３２において、それぞれの端面が対向するように配置されている。具体的には、第１挟持部材３４は、支持部３２の先端部側に配置されており、第２挟持部材３６は、第１挟持部材３４よりも支持部３２の基端部側に配置されている。第２挟持機構３０では、挟持部３３において、第１挟持部材３４の端面と第２挟持部材３６の端面との間で糸を挟持することにより、糸を保持する。 The first sandwiching member 34 and the second sandwiching member 36 are arranged in the support portion 32 so that their end faces face each other. Specifically, the first sandwiching member 34 is arranged on the tip end side of the support portion 32, and the second sandwiching member 36 is arranged on the proximal end portion side of the support portion 32 with respect to the first sandwiching member 34. ing. In the second sandwiching mechanism 30, the thread is held by sandwiching the thread between the end surface of the first sandwiching member 34 and the end surface of the second sandwiching member 36 in the sandwiching portion 33.

第１挟持部材３４の一部は、支持部３２に収容されており、第１挟持部材３４の一部は、支持部３２の凹部３５において露出している。第１挟持部材３４は、支持部３２に固定されていてもよいし、第１挟持部材３４と第２挟持部材３６との対向方向において移動自在（支持面３７ａに摺動可能）に設けられていてもよい。 A part of the first holding member 34 is housed in the support portion 32, and a part of the first holding member 34 is exposed in the recess 35 of the support portion 32. The first sandwiching member 34 may be fixed to the support portion 32, or is provided so as to be movable (sliding on the support surface 37a) in the facing direction between the first sandwiching member 34 and the second sandwiching member 36. You may.

第２挟持部材３６一部は、支持部３２に収容されており、第２挟持部材３６の一部は、支持部３２の凹部３５において露出している。第２挟持部材３６は、支持部３２において移動可能に設けられている。第２挟持部材３６は、上記対向方向において移動する。第２挟持部材３６は、ばね等の付勢部材（図示省略）によって、第１挟持部材３４に向かって付勢されている。すなわち、第２挟持部材３６と第１挟持部材３４とは、第２挟持部材３６に付勢部材以外の力が作用していない状態では、付勢部材の付勢力によって、互いの端面が当接している。 A part of the second holding member 36 is housed in the support portion 32, and a part of the second holding member 36 is exposed in the recess 35 of the support portion 32. The second holding member 36 is provided so as to be movable in the support portion 32. The second sandwiching member 36 moves in the opposite direction. The second sandwiching member 36 is urged toward the first sandwiching member 34 by an urging member (not shown) such as a spring. That is, in a state where a force other than the urging member is not acting on the second sandwiching member 36, the end faces of the second sandwiching member 36 and the first sandwiching member 34 are in contact with each other due to the urging force of the urging member. ing.

第２挟持部材３６は、支持部３２の移動に連動して移動する。第２挟持部材３６は、支持部３２の第２位置Ｐ２（図６（ｂ）参照）から第１位置Ｐ１（図６（ａ））への移動によって、第１挟持部材３４から離間する方向に移動する。具体的には、第２挟持部材３６は、支持部３２が第２位置Ｐ２から第１位置Ｐ１に移動すると、図示しないカム機構等によって、付勢部材の付勢方向に反した方向に押し下げられる。これにより、挟持部３３では、第１挟持部材３４と第２挟持部材３６との間に隙間（空間）が形成される。なお、第２挟持部材３６の移動は、支持部３２の移動と連動しなくてもよい。 The second sandwiching member 36 moves in conjunction with the movement of the support portion 32. The second sandwiching member 36 moves away from the first sandwiching member 34 by moving the support portion 32 from the second position P2 (see FIG. 6B) to the first position P1 (FIG. 6A). Moving. Specifically, when the support portion 32 moves from the second position P2 to the first position P1, the second holding member 36 is pushed down in a direction opposite to the urging direction of the urging member by a cam mechanism or the like (not shown). .. As a result, in the sandwiching portion 33, a gap (space) is formed between the first sandwiching member 34 and the second sandwiching member 36. The movement of the second holding member 36 does not have to be interlocked with the movement of the support portion 32.

続いて、合繊糸用スプライサ１を用いた絡合部の形成方法（糸継ぎ方法）について説明する。 Subsequently, a method of forming an entangled portion (thread splicing method) using the splicer 1 for synthetic fiber yarn will be described.

最初に、図６（ａ）に示されるように、第１糸Ｙ１及び第２糸Ｙ２を、合繊糸用スプライサ１にセットする。具体的には、第１糸Ｙ１及び第２糸Ｙ２を、糸継部１０のスリット１３を介してチャンバー１４に位置させると共に、第１位置Ｐ１に位置する第１挟持機構２０及び第２挟持機構３０に配置する。より詳細には、第１糸Ｙ１及び第２糸Ｙ２を、第１挟持機構２０の第１挟持部材２４と第２挟持部材２６との間に配置すると共に、第２挟持機構３０の第１挟持部材３４と第２挟持部材３６との間に配置する。これにより、第１糸Ｙ１及び第２糸Ｙ２は、第１挟持機構２０の第１当接面２７ｂ及び第２当接面２７ｃ上に載置されると共に、第２挟持機構３０の第１当接面３７ｂ及び第２当接面３７ｃ上に載置される。 First, as shown in FIG. 6A, the first yarn Y1 and the second yarn Y2 are set in the synthetic fiber splicer 1. Specifically, the first thread Y1 and the second thread Y2 are positioned in the chamber 14 via the slit 13 of the thread joint portion 10, and the first pinching mechanism 20 and the second pinching mechanism located at the first position P1. Place at 30. More specifically, the first thread Y1 and the second thread Y2 are arranged between the first pinching member 24 and the second pinching member 26 of the first pinching mechanism 20, and the first pinching mechanism 30 is held first. It is arranged between the member 34 and the second holding member 36. As a result, the first thread Y1 and the second thread Y2 are placed on the first contact surface 27b and the second contact surface 27c of the first pinching mechanism 20, and the first equivalent of the second pinching mechanism 30. It is placed on the contact surface 37b and the second contact surface 37c.

合繊糸用スプライサ１に第１糸Ｙ１及び第２糸Ｙ２をセットすると、操作部７を操作（押下）する。これにより、合繊糸用スプライサ１では、駆動部が作動し、第１挟持機構２０及び第２挟持機構３０が動作する。 When the first yarn Y1 and the second yarn Y2 are set in the synthetic yarn splicer 1, the operation unit 7 is operated (pressed). As a result, in the synthetic fiber splicer 1, the drive unit operates, and the first pinching mechanism 20 and the second pinching mechanism 30 operate.

具体的には、第１挟持機構２０において、第１挟持部材２４と第２挟持部材２６とにより第１糸Ｙ１及び第２糸Ｙ２が挟持される。また、第２挟持機構３０において、第１挟持部材３４と第２挟持部材３６とにより第１糸Ｙ１及び第２糸Ｙ２が挟持される。その後、図６（ｂ）に示されるように、第１挟持機構２０及び第２挟持機構３０は、第１位置Ｐ１から第２位置Ｐ２に移動する。これにより、図７に示されるように、第１糸Ｙ１及び第２糸Ｙ２は、挟持部２３と挟持部３３との間で弛んだ状態で保持される。また、第１糸Ｙ１及び第２糸Ｙ２は、少なくとも第２当接面２７ｃ及び第２当接面３７ｃに当接した状態で保持される。 Specifically, in the first pinching mechanism 20, the first thread Y1 and the second thread Y2 are pinched by the first pinching member 24 and the second pinching member 26. Further, in the second pinching mechanism 30, the first thread Y1 and the second thread Y2 are pinched by the first pinching member 34 and the second pinching member 36. After that, as shown in FIG. 6B, the first pinching mechanism 20 and the second pinching mechanism 30 move from the first position P1 to the second position P2. As a result, as shown in FIG. 7, the first thread Y1 and the second thread Y2 are held in a loose state between the sandwiching portion 23 and the sandwiching portion 33. Further, the first thread Y1 and the second thread Y2 are held in a state of being in contact with at least the second contact surface 27c and the second contact surface 37c.

また、操作部７が操作されると、空気流路１６を介して、噴射孔１６ａからチャンバー１４に対して空気が噴射される。これにより、チャンバー１４内に位置する第１糸Ｙ１及び第２糸Ｙ２は、空気の作用によって糸継ぎされ、絡合部が形成される。 Further, when the operation unit 7 is operated, air is injected from the injection hole 16a into the chamber 14 through the air flow path 16. As a result, the first yarn Y1 and the second yarn Y2 located in the chamber 14 are spliced by the action of air, and an entangled portion is formed.

続いて、操作部７の操作を解除する。これにより、合繊糸用スプライサ１では、噴射孔１６ａからチャンバー１４に対しての空気の噴射が停止されると共に、第１挟持機構２０及び第２挟持機構３０が動作する。 Subsequently, the operation of the operation unit 7 is released. As a result, in the synthetic fiber splicer 1, the injection of air from the injection hole 16a to the chamber 14 is stopped, and the first pinching mechanism 20 and the second pinching mechanism 30 operate.

具体的には、図６（ａ）に示されるように、第１挟持機構２０及び第２挟持機構３０は、第２位置Ｐ２から第１位置Ｐ１に移動する。この動作に伴って、第１挟持機構２０において、第２挟持部材２６が第１挟持部材２４から離間する方向に移動し、第１挟持部材２４と第２挟持部材２６とによる第１糸Ｙ１及び第２糸Ｙ２の挟持が解除される。第２挟持機構３０においても同様に、第２挟持部材３６が第１挟持部材３４から離間する方向に移動し、第１挟持部材３４と第２挟持部材３６とによる第１糸Ｙ１及び第２糸Ｙ２の挟持が解除される。なお、第１挟持機構２０が第２位置Ｐ２から第１位置Ｐ１に移動した後に、第１挟持部材２４と第２挟持部材２６とによる第１糸Ｙ１及び第２糸Ｙ２の挟持が解除されてもよい。同様に、第２挟持機構３０が第２位置Ｐ２から第１位置Ｐ１に移動した後に、第１挟持部材３４と第２挟持部材３６とによる第１糸Ｙ１及び第２糸Ｙ２の挟持が解除されてもよい。以上により、合繊糸用スプライサ１による、第１糸Ｙ１及び第２糸Ｙ２の糸継ぎが完了する。これにより、第１糸Ｙ１及び第２糸Ｙ２は、一本の糸になる。 Specifically, as shown in FIG. 6A, the first pinching mechanism 20 and the second pinching mechanism 30 move from the second position P2 to the first position P1. Along with this operation, in the first pinching mechanism 20, the second pinching member 26 moves in a direction away from the first pinching member 24, and the first thread Y1 and the second pinching member 26 are formed by the first pinching member 24 and the second pinching member 26. The pinching of the second thread Y2 is released. Similarly, in the second pinching mechanism 30, the second pinching member 36 moves in a direction away from the first pinching member 34, and the first thread Y1 and the second thread formed by the first pinching member 34 and the second pinching member 36 The pinching of Y2 is released. After the first pinching mechanism 20 moves from the second position P2 to the first position P1, the pinching of the first thread Y1 and the second thread Y2 by the first pinching member 24 and the second pinching member 26 is released. May be good. Similarly, after the second pinching mechanism 30 moves from the second position P2 to the first position P1, the pinching of the first thread Y1 and the second thread Y2 by the first pinching member 34 and the second pinching member 36 is released. You may. As described above, the splicing of the first yarn Y1 and the second yarn Y2 by the synthetic yarn splicer 1 is completed. As a result, the first thread Y1 and the second thread Y2 become one thread.

続いて、本実施形態に係る合繊糸用スプライサ１の作用効果について説明する。 Subsequently, the action and effect of the splicer 1 for synthetic yarn according to the present embodiment will be described.

図８に示されるように、比較例に係る糸継機構５Ａの第１挟持機構２０Ａでは、支持部２２Ａの第１当接面２７ｂ及び第２当接面２７ｃの位置関係が、本実施形態に係る第１挟持機構２０の支持部２２における第１当接面２７ｂ及び第２当接面２７ｃと反対になっている。すなわち、第２当接面２７ｃは、第１当接面２７ｂよりも下方に位置している。第２挟持機構３０Ａの支持部３２Ａについても、同様の構成である。 As shown in FIG. 8, in the first holding mechanism 20A of the thread splicing mechanism 5A according to the comparative example, the positional relationship between the first contact surface 27b and the second contact surface 27c of the support portion 22A is in the present embodiment. It is opposite to the first contact surface 27b and the second contact surface 27c in the support portion 22 of the first holding mechanism 20. That is, the second contact surface 27c is located below the first contact surface 27b. The support portion 32A of the second holding mechanism 30A has the same configuration.

この構成では、第１糸Ｙ１及び第２糸Ｙ２が、空気の噴射によって挟持部２３，３３を固定点としてチャンバー１４で振り回されたときに、第２当接面２７ｃ，３７ｃに接触することがある。このように、第１糸Ｙ１及び第２糸Ｙ２が第２当接面２７ｃ，３７ｃに接触すると、接触によって摩擦が生じる。これにより、第１糸Ｙ１及び第２糸Ｙ２が何らかのダメージを受けて、絡合部が適切に形成されないおそれがある。その結果、比較例に係る構成では、絡合部の引張伸度が低下し得る。 In this configuration, the first thread Y1 and the second thread Y2 may come into contact with the second contact surfaces 27c and 37c when they are swung in the chamber 14 with the sandwiching portions 23 and 33 as fixed points by the injection of air. be. In this way, when the first thread Y1 and the second thread Y2 come into contact with the second contact surfaces 27c and 37c, friction is generated by the contact. As a result, the first thread Y1 and the second thread Y2 may be damaged in some way, and the entangled portion may not be properly formed. As a result, in the configuration according to the comparative example, the tensile elongation of the entangled portion may decrease.

これに対して、図７に示される本実施形態に係る合繊糸用スプライサ１では、第２当接面２７ｃ，３７ｃは、第１当接面２７ｂ，３７ｂよりも上方に位置している。この構成では、第１糸Ｙ１及び第２糸Ｙ２は、挟持部２３，３３を固定点としてチャンバー１４内で振り回される。ここで、第２当接面２７ｃ，３７ｃは、第１当接面２７ｂ，３７ｂよりも上方に位置しているため、第１糸Ｙ１及び第２糸Ｙ２が配置されたときに、第１糸Ｙ１及び第２糸Ｙ２の自重によって、第１糸Ｙ１及び第２糸Ｙ２が少なくとも第２当接面２７ｃ，３７ｃに当接する。この状態において、第１糸Ｙ１及び第２糸Ｙ２が挟持部２３及び挟持部３３によって挟持され、第１糸Ｙ１及び第２糸Ｙ２に空気が噴射されると、第１糸Ｙ１及び第２糸Ｙ２は、実質的には、第２当接面２７ｃ，３７ｃを固定点として振り回される。そのため、合繊糸用スプライサ１では、振り回される第１糸Ｙ１及び第２糸Ｙ２において、支持部２２，３２との接触による摩擦が生じ難い。したがって、合繊糸用スプライサ１では、絡合部を適切に形成できる。その結果、合繊糸用スプライサ１では、絡合部の引張伸度の低下を抑制できる。 On the other hand, in the synthetic fiber splicer 1 according to the present embodiment shown in FIG. 7, the second contact surfaces 27c and 37c are located above the first contact surfaces 27b and 37b. In this configuration, the first thread Y1 and the second thread Y2 are swung around in the chamber 14 with the sandwiching portions 23 and 33 as fixed points. Here, since the second contact surfaces 27c and 37c are located above the first contact surfaces 27b and 37b, the first yarn is arranged when the first yarn Y1 and the second yarn Y2 are arranged. Due to the weight of Y1 and the second thread Y2, the first thread Y1 and the second thread Y2 come into contact with at least the second contact surfaces 27c and 37c. In this state, when the first thread Y1 and the second thread Y2 are sandwiched by the sandwiching portion 23 and the sandwiching portion 33 and air is injected into the first thread Y1 and the second thread Y2, the first thread Y1 and the second thread Y2 is substantially swung around the second contact surfaces 27c and 37c as fixed points. Therefore, in the synthetic fiber splicer 1, friction is unlikely to occur due to contact with the support portions 22 and 32 in the first yarn Y1 and the second yarn Y2 that are swung around. Therefore, in the synthetic fiber splicer 1, the entangled portion can be appropriately formed. As a result, in the synthetic fiber splicer 1, it is possible to suppress a decrease in the tensile elongation of the entangled portion.

具体的に、実施例及び比較例に基づいて、合繊糸用スプライサ１の効果を説明する。図９（ａ）～図９（ｄ）では、絡合部が形成されていない合成繊維における引張伸度の測定値を基準値として、実施例及び比較例について、基準値からの引張伸度の低下量（％）を示している。実施例は、本実施形態に係る合繊糸用スプライサ１によって絡合部を形成した糸の結果を示している。比較例は、図８に示される糸継機構５Ａを備える合繊糸用スプライサによって絡合部を形成した糸の結果を示している。測定は、ＵＳＴＥＲ社製のＴＥＮＳＯＲＡＰＩＤ４（商品名）を用いて、太さや分子構造の異なる４種類の糸（糸Ａ～糸Ｄ）について行った。各糸は、半延伸糸（ＰＯＹ：Pre Oriented Yarn）である。 Specifically, the effect of the splicer 1 for synthetic yarn will be described based on Examples and Comparative Examples. In FIGS. 9 (a) to 9 (d), the measured value of the tensile elongation in the synthetic fiber in which the entangled portion is not formed is used as a reference value, and the tensile elongation from the reference value is used in Examples and Comparative Examples. The amount of decrease (%) is shown. The examples show the result of the yarn which formed the entangled part by the splicer 1 for synthetic fiber yarn which concerns on this embodiment. The comparative example shows the result of the yarn in which the entangled portion is formed by the splicer for synthetic yarn provided with the yarn splicing mechanism 5A shown in FIG. The measurement was performed using TENSORAPID4 (trade name) manufactured by USTER for four types of threads (threads A to D) having different thicknesses and molecular structures. Each yarn is a semi-drawn yarn (POY: Pre Oriented Yarn).

In Comparative Example 2 , the measured value was 120.0% with respect to the reference value (137.3%) of the yarn B, and the amount of decrease in tensile elongation from the reference value was "-17.3%". was gotten. In Example 2 , the measured value was 124.5% with respect to the reference value of the yarn B, and the amount of decrease in tensile elongation from the reference value was "-12.8%".

（比較例３、実施例３）
糸Ｃは、８４［ｄｔｅｘ］－３６［ｆ］の糸である。比較例３では、糸Ｃの基準値（１１９．７％）に対して、測定値が１０７．６％であり、基準値からの引張伸度の低下量が「－１２．１％」の結果が得られた。実施例３では、糸Ｃの基準値に対して、測定値が１０９．８％であり、基準値からの引張伸度の低下量が「－９．９％」の結果が得られた。 (Comparative Example 3, Example 3)
The thread C is a thread of 84 [dtex] -36 [f]. In Comparative Example 3 , the measured value was 107.6% with respect to the reference value (119.7%) of the yarn C, and the amount of decrease in tensile elongation from the reference value was "-12.1%". was gotten. In Example 3 , the measured value was 109.8% with respect to the reference value of the yarn C, and the amount of decrease in tensile elongation from the reference value was "-9.9%".

（比較例４、実施例４）
糸Ｄは、９０［ｄｔｅｘ］－３６［ｆ］の糸である。比較例４では、糸Ｄの基準値（１０３．４％）に対して、測定値が９７．１％であり、基準値からの引張伸度の低下量が「－６．３％」の結果が得られた。実施例４では、糸Ｄの基準値に対して、測定値が１０１．９％であり、基準値からの引張伸度の低下量が「－１．５％」の結果が得られた。 (Comparative Example 4, Example 4)
The thread D is a thread of 90 [dtex] -36 [f]. In Comparative Example 4 , the measured value was 97.1% with respect to the reference value (103.4%) of the yarn D, and the amount of decrease in tensile elongation from the reference value was "-6.3%". was gotten. In Example 4 , the measured value was 101.9% with respect to the reference value of the yarn D, and the amount of decrease in tensile elongation from the reference value was "-1.5%".

以上のように、太さや分子構造が異なる４種類の糸（糸Ａ～糸Ｄ）において、本実施形態に係る合繊糸用スプライサ１によって絡合部を形成した場合、比較例に比べて、何れも引張伸度の低下量が小さい。そのため、合繊糸用スプライサ１で絡合部を形成した場合には、引張伸度の低下を抑制できることが確認できた。なお、一般的に、糸の種類（例えば太さやフィラメント数）が異なる場合、引張伸度の値が異なるため、許容される引張伸度の低下割合も異なる。 As described above, when the entangled portion is formed by the synthetic fiber splicer 1 according to the present embodiment in four types of yarns (threads A to D) having different thicknesses and molecular structures, any of the four types of yarns (threads A to D) are compared with the comparative example. However, the amount of decrease in tensile elongation is small. Therefore, it was confirmed that when the entangled portion was formed by the splicer 1 for synthetic fiber yarn, the decrease in tensile elongation could be suppressed. In general, when the type of yarn (for example, the thickness and the number of filaments) is different, the value of the tensile elongation is different, so that the permissible reduction rate of the tensile elongation is also different.

本実施形態に係る合繊糸用スプライサ１では、挟持部２３，３３は、互いに対向する第１挟持部材２４，３４及び第２挟持部材２６，３６を有している。第１当接面２７ｂ，３７ｂ及び第２当接面２７ｃ，３７ｃは、第１挟持部材２４，３４と第２挟持部材２６，３６とが当接する位置に設けられている。この構成では、第１挟持部材２４，３４と第２挟持部材２６，３６とによって挟持される第１糸Ｙ１及び第２糸Ｙ２を、第２当接面２７ｃ，３７ｃに確実に当接させることができる。そのため、第１糸Ｙ１及び第２糸Ｙ２は、確実に第２当接面２７ｃ，３７ｃを固定点として振り回される。したがって、振り回される第１糸Ｙ１及び第２糸Ｙ２において、支持部２２，３２との接触による摩擦が生じない。その結果、合繊糸用スプライサ１では、絡合部を適切に形成でき、絡合部の引張伸度の低下を抑制できる。 In the synthetic fiber splicer 1 according to the present embodiment, the sandwiching portions 23 and 33 have first sandwiching members 24 and 34 and second sandwiching members 26 and 36 facing each other. The first contact surfaces 27b, 37b and the second contact surfaces 27c, 37c are provided at positions where the first sandwiching members 24, 34 and the second sandwiching members 26, 36 abut. In this configuration, the first thread Y1 and the second thread Y2 sandwiched by the first sandwiching members 24, 34 and the second sandwiching members 26, 36 are surely brought into contact with the second contact surfaces 27c, 37c. Can be done. Therefore, the first thread Y1 and the second thread Y2 are surely swung around the second contact surfaces 27c and 37c as fixed points. Therefore, in the first thread Y1 and the second thread Y2 that are swung around, friction due to contact with the support portions 22 and 32 does not occur. As a result, in the synthetic fiber splicer 1, the entangled portion can be appropriately formed, and the decrease in the tensile elongation of the entangled portion can be suppressed.

本実施形態に係る合繊糸用スプライサ１では、第２当接面２７ｃ，３７ｃは、第１挟持機構２０及び第２挟持機構３０対向方向に沿って延在する平坦面である。この構成では、振り回される第１糸Ｙ１及び第２糸Ｙ２において、支持部２２，３２との接触による摩擦をより一層回避できる。 In the synthetic fiber splicer 1 according to the present embodiment, the second contact surfaces 27c and 37c are flat surfaces extending along the facing directions of the first sandwiching mechanism 20 and the second sandwiching mechanism 30. In this configuration, in the first thread Y1 and the second thread Y2 that are swung around, friction due to contact with the support portions 22 and 32 can be further avoided.

本実施形態に係る合繊糸用スプライサ１では、第１当接面２７ｂ，３７ｂと第２当接面２７ｃ，３７ｃとの差Ｇが、０．５ｍｍ以上１．５ｍｍ以下である。この構成では、第１糸Ｙ１及び第２糸Ｙ２をより確実に第２当接面２７ｃ，３７ｃに当接させることができる。したがって、合繊糸用スプライサ１では、絡合部を適切に形成でき、絡合部の引張伸度の低下を抑制できる。 In the synthetic fiber splicer 1 according to the present embodiment, the difference G between the first contact surfaces 27b and 37b and the second contact surfaces 27c and 37c is 0.5 mm or more and 1.5 mm or less. In this configuration, the first thread Y1 and the second thread Y2 can be more reliably brought into contact with the second contact surfaces 27c and 37c. Therefore, in the synthetic fiber splicer 1, the entangled portion can be appropriately formed, and the decrease in the tensile elongation of the entangled portion can be suppressed.

具体的に、測定結果に基づいて、第１当接面２７ｂ，３７ｂと第２当接面２７ｃ，３７ｃとの差Ｇによる効果を説明する。図１０（ａ）及び図１０（ｂ）では、差Ｇが、０ｍｍ、０．５ｍｍ、１．０ｍｍ及び１．５ｍｍの場合について、測定を行った結果を示している。図１０（ａ）及び図１０（ｂ）では、絡合部が形成されていない合成繊維における引張伸度の測定値を基準値として、各差Ｇについて、基準値からの引張伸度の低下量（％）を示している。測定には、ＵＳＴＥＲ社製のＴＥＮＳＯＲＡＰＩＤ４（商品名）を用いた。図１０（ａ）では、合繊糸用スプライサ１において、チャンバー１４の直径がφ６．０ｍｍ、噴射孔１６ａの直径がφ１．３ｍｍの構成での結果を示している。図１０（ｂ）では、合繊糸用スプライサ１において、チャンバー１４の直径がφ３．５ｍｍ、噴射孔１６ａの直径がφ１．０ｍｍの構成での結果を示している。図１０（ａ）及び図１０（ｂ）では、差Ｇが０ｍｍ、０．５ｍｍ、１．０ｍｍ及び１．５ｍｍの場合について、それぞれ６回測定を行った。 Specifically, the effect of the difference G between the first contact surfaces 27b and 37b and the second contact surfaces 27c and 37c will be described based on the measurement results. 10 (a) and 10 (b) show the results of measurement when the difference G is 0 mm, 0.5 mm, 1.0 mm and 1.5 mm. In FIGS. 10 (a) and 10 (b), the amount of decrease in tensile elongation from the reference value is used as a reference value for each difference G, using the measured value of tensile elongation in the synthetic fiber in which the entangled portion is not formed as a reference value. (%) Is shown. TENSORAPID4 (trade name) manufactured by USTER was used for the measurement. FIG. 10A shows the results of the synthetic fiber splicer 1 in which the diameter of the chamber 14 is φ6.0 mm and the diameter of the injection hole 16a is φ1.3 mm. FIG. 10B shows the results of the synthetic fiber splicer 1 in which the diameter of the chamber 14 is φ3.5 mm and the diameter of the injection hole 16a is φ1.0 mm. In FIGS. 10 (a) and 10 (b), measurements were performed 6 times when the difference G was 0 mm, 0.5 mm, 1.0 mm, and 1.5 mm, respectively.

図１０（ａ）及び図１０（ｂ）に示されるように、差Ｇが０ｍｍの場合、すなわち、第１当接面２７ｂ，３７ｂと第２当接面２７ｃ，３７ｃとの高さ位置に差が無い場合（同じ高さ位置である場合）には、引張伸度の低下量にばらつきが生じている。具体的には、差Ｇが０ｍｍの場合、図１０（ａ）に示される測定結果では、低下量の最大値と最小値との差が７．０％であり、図１０（ｂ）に示される測定結果では、低下量の最大値と最小値との差が１０．１％である。これに対して、差Ｇが０．５ｍｍ、１．０ｍｍ及び１．５ｍｍの場合には、差Ｇが０ｍｍの場合に比べて、何れも低下量のばらつきが小さい。また、差Ｇが０．５ｍｍ、１．０ｍｍ及び１．５ｍｍの場合には、差Ｇが０ｍｍの場合に比べて、何れも引張伸度の平均低下量が小さい。そのため、合繊糸用スプライサ１で絡合部を形成した場合には、引張伸度の低下量のばらつきを抑制できると共に、引張伸度の低下が抑制できることが確認できた。 As shown in FIGS. 10A and 10B, when the difference G is 0 mm, that is, the difference is in the height position between the first contact surfaces 27b and 37b and the second contact surfaces 27c and 37c. If there is no such item (at the same height position), the amount of decrease in tensile elongation is uneven. Specifically, when the difference G is 0 mm, the difference between the maximum value and the minimum value of the amount of decrease is 7.0% in the measurement result shown in FIG. 10 (a), which is shown in FIG. 10 (b). According to the measurement results, the difference between the maximum value and the minimum value of the amount of decrease is 10.1%. On the other hand, when the difference G is 0.5 mm, 1.0 mm and 1.5 mm, the variation in the amount of reduction is smaller than when the difference G is 0 mm. Further, when the difference G is 0.5 mm, 1.0 mm and 1.5 mm, the average decrease in tensile elongation is smaller than when the difference G is 0 mm. Therefore, it was confirmed that when the entangled portion is formed by the synthetic fiber splicer 1, the variation in the amount of decrease in tensile elongation can be suppressed and the decrease in tensile elongation can be suppressed.
