[0001] 本発明は、異なる糸の末端同士を撚り継ぎするスプライサ装置に関する。  [0001] The present invention relates to a splicer device for twisting together ends of different yarns.
背景技術  Background art
[0002] 従来から、編地や織地を形成する際には、異なる糸の末端同士の糸継ぎが必要と なる。糸継ぎには、結び目を形成するノッタや、糸の末端の繊維の撚りをいつたんほ どいたあとで絡み合うように撚り合わせて継ぎ目を形成するスプライサなどが用いられ る。ノッタによる糸継ぎは、異なる糸の末端同士で結び目を形成して行われるので、 糸継ぎ部に結び目が生じてしまう。結び目の部分は、径が太くなり、編地や織地を形 成する装置の途中などに引っ掛かって、円滑な動作が困難になってしまう。スプライ サによる糸継ぎでは、糸継ぎ部での径の増大を抑えることが可能なので、編成や製 織の動作を円滑に継続させやすレ、。  Conventionally, when forming a knitted fabric or a woven fabric, it is necessary to splice ends of different yarns. For the yarn splicing, a knotter that forms a knot, a splicer that twists the fibers at the end of the yarn and twists them so that they are intertwined to form a seam, and the like are used. Since knitting with a knotter is performed by forming a knot between the ends of different yarns, a knot is produced at the piecing portion. The knot portion has a large diameter and is caught in the middle of an apparatus for forming a knitted fabric or a woven fabric, making smooth operation difficult. In splicing with a splicer, it is possible to keep the knitting and weaving operations smoothly because it is possible to suppress an increase in diameter at the splicing section.
スプライサは、糸を卷き取って織機などに装着するコーンを形成するワインダなどで の糸継ぎに使用されている。スプライサとしては、糸継ぎする糸の末端の向きを揃え て行い、直線状に接続される糸から末端同士が絡み合う糸継ぎ部が横に延びだして 、いわば T字形に糸継ぎ部を形成するものと（たとえば、特開 2004— 27463号公報 参照。）、糸の末端の向きを互いに対向するようにして行レ、、糸継ぎ部が直線状に接 続される糸の周囲を覆うように絡みあって、いわば I字形に糸継ぎ部を形成するものと がある（たとえば、特開 2004— 131276号公報参照。）。  Splicers are used for splicing yarns in winders that form a cone that winds the yarn and attaches it to a loom. As a splicer, the ends of the yarns to be spliced are aligned, and the spliced portion where the ends are intertwined from the yarns connected in a straight line extends laterally, forming a so-called T-shaped spliced portion. (See, for example, Japanese Patent Application Laid-Open No. 2004-27463) The yarn ends are arranged so that the ends of the yarns are opposed to each other, and the yarn splices are entangled so as to cover the periphery of the yarn that is connected linearly. In other words, there is a so-called I-shaped yarn splicing portion (see, for example, JP-A-2004-131276).
編地は基本的に 1本の編糸で形成されるので、異なる糸を継ぎ足すと、同一の糸で は得られないような性質や色の変化などを与えることができる。編み機では、複数の 糸を交互に使用することも可能であるけれども、形成される編地で同じ糸を使用する 部分が離れていると、渡り糸が生じる。糸継ぎで糸を切り換えれば、渡り糸は生じない 。また、編み機で複数の糸が使用可能であっても、糸を供給する部分は狭い領域に 限られるので、使用可能な糸の数にも制限がある。編み機で糸継ぎを必要とする場 合、結び目を形成するノッタなどを用いている。ノッタを用いる場合、結び目の部分で 糸の径が太くなり、装置の円滑な稼働が阻害され、形成される編地でも結び目が表 面に出ないように処理する必要がある。スプライサで糸継ぎを行えば、糸継ぎ部分の 処理が簡単になることが期待される。し力 ながら、従来のワインダなどに備えられる スプライサは大型であり、編み機などの糸の供給経路に設けることはできない。 特開 2004— 27463号公報および特開 2004— 131276号公報には、各部の配置 や装置を小型化するための具体的構造についての記載はない。編み機に使用する スプライサは、たとえば色を切り換えるような場合、前述の I字形の糸継ぎ部では、糸 継ぎ部が中間の色の部分となってしまう。前述の T字形の糸継ぎ部であれば、糸継ぎ 部は前後の糸の外部に出るので、前後の糸の色を中間色の部分なしに切り換えるこ とができる。編み機では、色を変える模様の境界部分で糸継ぎが行われ、糸継ぎ部 が編地の裏側などに隠れるような制御も可能である。したがって、編み機などには、 前述の T字形の糸継ぎ部を形成するスプライサが好ましい。特開 2004— 27463号 公報には、糸継ぎ用のヘッド部分の機構については詳細に説明されている。編み機 などに組み込むためには、糸継ぎの対象となる糸を自動的にヘッドに挿入することが 必要となる。特開 2004— 27463号公報には、ヘッドに糸を自動的に挿入することが 可能な糸挿入の機構は記載されていない。 Since the knitted fabric is basically formed of a single knitting yarn, adding different yarns can give changes in properties and colors that cannot be obtained with the same yarn. In a knitting machine, it is possible to use a plurality of yarns alternately. However, if the portion of the knitted fabric that uses the same yarns is separated, a crossover yarn is generated. If the thread is switched by piecing, no crossover thread is generated. Even if a plurality of yarns can be used on the knitting machine, the number of yarns that can be used is limited because the portion for supplying the yarn is limited to a narrow area. When a knitting machine requires splicing, a knotter that forms a knot is used. When using a knotter, at the knot It is necessary to treat the yarn so that the diameter of the yarn becomes thick, the smooth operation of the device is hindered, and even in the knitted fabric that is formed, the knot does not appear on the surface. If splicing is performed with a splicer, the processing of the spliced part is expected to be simplified. However, the splicer provided in a conventional winder is large and cannot be provided in the yarn supply path of a knitting machine or the like. Japanese Patent Application Laid-Open Nos. 2004-27463 and 2004-131276 do not describe the arrangement of each part and the specific structure for downsizing the device. For example, if the splicer used in a knitting machine switches colors, the above-mentioned I-shaped yarn splicing portion has an intermediate color portion. In the case of the T-shaped yarn splicing portion described above, the yarn splicing portion protrudes outside the front and rear yarns, so that the color of the front and rear yarns can be switched without the intermediate color portion. In a knitting machine, it is possible to perform control so that yarn joining is performed at the boundary of the pattern that changes color and the yarn joining part is hidden behind the knitted fabric. Therefore, for the knitting machine or the like, a splicer that forms the above-described T-shaped yarn splicing portion is preferable. Japanese Patent Laid-Open No. 2004-27463 describes in detail the mechanism of the head portion for piecing. In order to incorporate it into a knitting machine, it is necessary to automatically insert the yarn to be spliced into the head. Japanese Patent Application Laid-Open No. 2004-27463 does not describe a thread insertion mechanism that can automatically insert a thread into the head.
また特開 2004— 27463号公報および特開 2004— 131276号公報には、繊維塵 などによる動作不良を防ぐ構成について、何ら記載されていない。  Japanese Patent Application Laid-Open No. 2004-27463 and Japanese Patent Application Laid-Open No. 2004-131276 do not describe any configuration for preventing malfunction due to fiber dust or the like.

糸継ぎ動作は、制御部 50の制御によって実行され、糸 12の変更が必要になった 時点で開始される。ステップ siでは、複数の糸選択板 10の先端のリング 11には糸 1 2がそれぞれ揷通されている。このうち、少なくとも 1本の糸 12bは、使用中である。そ の他の糸 12の末端は、糸保持 13で保持されている。糸保持 13での待機中の糸 12 の末端の保持は、セパレータ 15の手前側で行われる。使用中の糸 12bは、セパレー タ 15の奥側を通過して下方に延びるように、待機中の糸 12と分離されている。各部 の状態としては、糸押さえ 23は、 OFFであり、糸を押さえていない状態である。糸保 持 13は、 ONであり、待機中の糸 12の末端は保持されている状態である。サクシヨン 19は、 OFFであり、糸を吸引しない状態である。カツタ 30は、 OFFであり、 2枚の刃 3 0a, 30bが開いた状態となる。糸クランプ 31は、スプライスノズル 7の入口を塞がない 状態である。つまりカム 36は、原点位置にある。スプライスノズル 7は、 OFFであり、糸 継ぎのための圧縮流体の流れが生じていない状態である。糸保持 13では、保持する 糸 12の先端が糸保持 13から下方へ出るように保持する。糸保持 13の下方から出て いる糸 12の先端は、サクシヨン 19を ONにすれば吸引することができる。糸案内レバ 一 14は、原点位置にある。  The yarn splicing operation is executed under the control of the control unit 50, and is started when the yarn 12 needs to be changed. In step si, the threads 1 and 2 are threaded through the rings 11 at the tips of the plurality of thread selection plates 10, respectively. Of these, at least one thread 12b is in use. The other end of the yarn 12 is held by a yarn holder 13. The holding of the end of the waiting yarn 12 by the yarn holding 13 is performed on the front side of the separator 15. The thread 12b in use is separated from the waiting thread 12 so as to pass through the back side of the separator 15 and extend downward. As for the state of each part, the thread presser 23 is OFF and the thread is not pressed. The yarn holding 13 is ON, and the end of the waiting yarn 12 is held. Succession 19 is OFF and does not suck the yarn. The cutter 30 is OFF, and the two blades 30a and 30b are opened. The thread clamp 31 is in a state where the inlet of the splice nozzle 7 is not blocked. That is, the cam 36 is at the origin position. The splice nozzle 7 is OFF, and there is no flow of compressed fluid for piecing. In the thread holding 13, the thread 12 to be held is held so that the tip of the thread 12 protrudes downward from the thread holding 13. The tip of the thread 12 coming out from the lower side of the thread retainer 13 can be sucked if the suction 19 is turned on. Thread guide lever 14 is at the origin position.
ステップ s2では、図 10、図 11に示すように、制御部 50は、糸選択部 3で少なくとも 1 本の糸 12aを選択させる。特に図 11に明確に示されているように、選択された糸 12a は、糸案内レバー 14の角変位の移動軌跡に力かる位置で、先端 14aによって引っ掛 けられる位置まで移動する。糸案内レバー 14の側面突起 14bは、使用中の糸 12bを 引っ掛けることができる位置に設けられている。  In step s2, as shown in FIGS. 10 and 11, the control unit 50 causes the yarn selection unit 3 to select at least one yarn 12a. In particular, as clearly shown in FIG. 11, the selected thread 12a moves to a position where it is caught by the tip 14a at a position that is applied to the movement locus of the angular displacement of the thread guide lever 14. The side projection 14b of the thread guide lever 14 is provided at a position where the thread 12b in use can be hooked.
ステップ s3では、制御部 50は、第 1モータ 4を制御し、糸案内レバー 14の原点位置 力 作用位置に向力 角変位を開始させる。糸案内レバー 14が角変位中に、先端 1 4aで糸選択部 3によって選択されている糸 12aを引っ掛けると、図 12に示すように、 側方に引き出すことができる。糸 12aの末端は、糸保持 13で他の待機中の糸の末端 とともに保持されているけれども、他の糸については図示を省略する。糸案内レバー 14の角変位の途中では、側面突起 14bで使用中の糸 12bを引っ掛ける。使用中の 糸 12bは、側面突起 14bに引っ掛かるまではセパレータ 15の奥側を通っている。側 面突起 14bに引っ掛かると、糸案内レバー 14の角変位によって、図 12から図 13に 示すように、セパレータ 15の側端を越えて、セパレータ 15の手前側に移動し、 OFF で開いている糸押さえ 23内に入り込む。糸押さえ 23には、図 10に示すように、待機 中の糸 12も入り込んでいる。ただし、使用中の糸 12bよりも右側となる糸 12cを選択 する場合は、側面突起 14bは使わないで、選択した糸 12cが使用中の糸 12bを連行 する。これらの糸 12， 12bは、糸押さえ 23を〇Nにすることによって、一時的に保持 することが可能になる。 In step s3, the control unit 50 controls the first motor 4 to start the directional force angular displacement to the origin position force acting position of the yarn guide lever 14. When the thread guide lever 14 is angularly displaced and the thread 12a selected by the thread selector 3 is hooked at the tip 14a, as shown in FIG. Can be pulled out to the side. The end of the yarn 12a is held together with the other ends of the waiting yarn by the yarn holding unit 13, but the illustration of the other yarns is omitted. During the angular displacement of the thread guide lever 14, the thread 12b being used is hooked by the side protrusion 14b. The thread 12b in use passes through the back side of the separator 15 until it is caught by the side protrusion 14b. When hooked on the side protrusion 14b, the angular displacement of the thread guide lever 14 moves past the side edge of the separator 15 to the front side of the separator 15 as shown in FIGS. Enter the thread retainer 23. As shown in FIG. 10, the thread retainer 23 also enters the thread retainer 23. However, when selecting the thread 12c on the right side of the currently used thread 12b, the side thread 14b is not used, and the selected thread 12c entrains the used thread 12b. These threads 12 and 12b can be temporarily held by setting the thread retainer 23 to 0N.
ステップ s4では、制御部 50は、糸案内レバー 14が作用位置に到達し角変位を終 了させる。糸案内レバー 14の先端 14aは、スプライスノズノレ 7の下方の入口まで選択 された糸 12aを案内し、選択された糸 12aはスプライスノズル 7に設けられる糸継ぎ用 の溝 7aに嵌まり込む。選択された糸 12aの末端側は、スプライスノズル 7の上方の糸 保持 13で保持されている。使用中の糸 12bは、セパレータ 15の側端を乗り越えて、 OFFで開いた状態の糸押さえ 23に挿入されて、糸選択板 1 Obのリング 11 bまで延び る。  In step s4, the control unit 50 ends the angular displacement when the yarn guide lever 14 reaches the operating position. The tip 14 a of the yarn guide lever 14 guides the selected yarn 12 a to the lower entrance of the splice nozzle 7, and the selected yarn 12 a is fitted into a splicing groove 7 a provided in the splice nozzle 7. The end of the selected yarn 12a is held by a yarn holder 13 above the splice nozzle 7. The thread 12b in use gets over the side end of the separator 15, is inserted into the thread retainer 23 that is open when OFF, and extends to the ring 11b of the thread selection plate 1 Ob.
ステップ s5では、制御部 50は、吸引制御用電磁弁を制御してサクシヨン 19を ONに し、これ同時に、糸押さえ制御用電磁弁を制御して糸押さえ 23を ONにする。サクシ ヨン 19が ONになるので、図 13に示すように、選択された糸 12aを含めて、糸保持 13 に保持されている糸 12， 12aの糸保持 13から下方へ出ている先端は、サクシヨン 19 によって吸引される。また糸押さえ 23によって、使用中の糸 12bが押さえられる。 ステップ s6では、制御部 50は、第 2モータ 5を制御して、カム 36を原点位置から角 変位を開始させる。これによつて糸クランプ 31の可動部 31bが角変位され、 ONとな つて、スプライスノズル 7の溝 7aの入口が塞がれ、同時に溝 7aに嵌まり込んでいる選 択された糸 12aおよび使用中の糸 12bが、固定部 31aと協働してクランプされる。ま たカム 36を原点位置から角変位を開始させることで、カツタ 30が ONとなり、溝 7aの 出口付近で、選択された糸 12aおよび使用中の糸 12bを切断する。このようにステツ プ s6では、図 14に状態から図 15の状態に動作させる。 In step s5, the control unit 50 controls the suction control solenoid valve to turn on the suction 19 and simultaneously controls the thread presser control solenoid valve to turn on the thread presser 23. Since the succession 19 is turned ON, as shown in FIG. 13, the tip of the yarns 12 and 12a held in the yarn holding 13 including the selected yarn 12a is projected downward from the yarn holding 13 as shown in FIG. Sucked by suction 19 In addition, the thread presser 23 holds the thread 12b in use. In step s6, the control unit 50 controls the second motor 5 to start the angular displacement of the cam 36 from the origin position. As a result, the movable part 31b of the thread clamp 31 is angularly displaced and turned ON, so that the inlet of the groove 7a of the splice nozzle 7 is closed and at the same time the selected thread 12a and the thread 12a fitted into the groove 7a and The thread 12b in use is clamped in cooperation with the fixing part 31a. Also, by starting the angular displacement of the cam 36 from the origin position, the cutter 30 is turned on and the groove 7a Cut the selected thread 12a and the thread 12b in use near the exit. In this way, in step s6, the state shown in FIG. 14 is changed to the state shown in FIG.
次にステップ s7では、制御部 50は、供給制御用電磁弁を制御して、スプライスノズ ル 7の溝 7aへの圧縮空気の供給を開始し、糸継ぎを開始する。スプライスノズル 7の 溝 7aには圧縮空気のノズノレが設けられ、入口から出口に向力 方向の空気流を形成 し、空気流内で糸 12a， 12bの撚りをいつたん解いてから再び絡めてスプライスによる 糸継ぎを行う。ステップ s8では、制御部 50は、糸保持制御用電磁弁を制御して糸保 持 13を OFFにさせ、糸 12の保持を解除させる。選択された糸 12aの端部は、糸保持 13から解放されて、糸屑としてサクシヨン 19に吸引される。ステップ s6で糸押さえ 23 を〇Nにしているので、使用中の糸 12bを含めて、待機中の糸 12は糸押さえ 23によ つて押えられている。たとえばサクシヨン 19の吸引力が充分であれば、糸押さえ 23が 設けられなくても、糸保持 13を OFFにすることができる。  Next, in step s7, the control unit 50 controls the supply control solenoid valve to start the supply of compressed air to the groove 7a of the splice nozzle 7 and to start piecing. The groove 7a of the splice nozzle 7 is provided with a nose of compressed air, forming an air flow in the direction of the force from the inlet to the outlet, unwinding the yarns 12a and 12b in the air flow, and then entwining them again and splicing. Perform splicing with. In step s8, the control unit 50 controls the yarn holding control electromagnetic valve to turn off the yarn holding 13 and release the holding of the yarn 12. The end portion of the selected yarn 12a is released from the yarn holder 13 and is sucked into the succession 19 as yarn waste. Since the thread presser 23 is set to “N” in step s6, the waiting thread 12 including the currently used thread 12b is pressed by the thread presser 23. For example, if the suction force of the suction 19 is sufficient, the yarn holding 13 can be turned off even if the yarn presser 23 is not provided.
ステップ s9では、制御部 50は、供給制御用電磁弁を制御して、スプライスノズル 7 の溝 7aへの圧縮空気の供給を停止させ、糸継ぎを終了する。ステップ slOでは、制 御部 50は、糸保持制御用電磁弁を制御して糸保持 13を ONにし、待機状態の糸 12 の末端付近を保持する。使用中の糸 12bは、ステップ s6でのカツタ 30による切断箇 所から上方の部分が糸保持 13で保持され、待機状態となる。ステップ sl lでは、制御 部 50は、第 2モータ 5を制御し、ステップ s6における角変位方向とは逆の方向に、力 ム 36を原点位置まで角変位させる。糸クランプ 31は、 OFFとなって糸継ぎされた糸 が解放され、スプライスノズノレ 7の溝 7aの入口が開く。さらにカツタ 30も OFFとなって 、刃先が開く。  In step s9, the control unit 50 controls the supply control solenoid valve to stop the supply of compressed air to the groove 7a of the splice nozzle 7 and finish the piecing. In step slO, the control unit 50 controls the yarn holding control electromagnetic valve to turn on the yarn holding 13 and holds the vicinity of the end of the yarn 12 in the standby state. The thread 12b in use is held by the thread retainer 13 at the upper part from the cutting position by the cutter 30 in step s6, and enters a standby state. In step sl l, the control unit 50 controls the second motor 5 and angularly displaces the force force 36 to the origin position in a direction opposite to the angular displacement direction in step s6. The thread clamp 31 is turned OFF, the spliced thread is released, and the inlet of the groove 7a of the splice nozzle 7 is opened. In addition, the cutter 30 is turned off and the cutting edge opens.
次のステップ sl 2では、制御部 50は、吸引制御用電磁弁および糸押さえ制御用電 磁弁を制御して、サクシヨン 19と糸押さえ 23とを同時に OFFにする。サクシヨン 19に よる糸 12の吸引が停止され、糸押さえ 23による糸 12の押さえが停止される。ステップ sl3では、制御部 50は、第 1モータ 4を、ステップ s3とは逆方向に回転させ、糸案内 レバー 14を原点位置に戻し、糸継ぎ動作が終了する。  In the next step sl 2, the control unit 50 controls the suction control solenoid valve and the thread presser control electromagnetic valve to turn off the succession 19 and the thread presser 23 simultaneously. The suction of the thread 12 by the suction 19 is stopped, and the pressing of the thread 12 by the thread retainer 23 is stopped. In step sl3, the control unit 50 rotates the first motor 4 in the direction opposite to that in step s3, returns the yarn guide lever 14 to the origin position, and the yarn splicing operation ends.

FIG. 18 is an enlarged plan view showing the vicinity of the yarn guide 20. As shown in Figure 18, The groove 7a of the price nozzle 7 is formed with a V-shaped space 7b that is recessed in a V-shape and a yarn splicing space 7c that continues to the deepest region of the V-shaped space 7b. The yarn splicing space 7c is formed so as to swell more than the deepest region of the V-shaped space 7b.
図 18に示すように、糸ガイド 20の案内面 20aが、糸継ぎ空間 7cよりも予め定める第 1設定距離 D1以上、サクシヨン 19の吸引方向と反対方向に離れるように形成される。 これによつて、編成時の使用中の糸は、糸ガイド 20に案内されるとともに、スプライサ 装置 1から排出された使用中の糸を導糸する導糸部 202とに案内される。テンション が与えられることで、図 17に示すように糸が張られ、使用中の糸は、糸継ぎ空間 7cか ら脱出して、 V字状空間 7bに位置する。これによつて糸継ぎ空間 7cに比べて広い領 域を通過することで、円滑に糸の繰出しを行うことができる。  As shown in FIG. 18, the guide surface 20a of the yarn guide 20 is formed so as to be separated from the yarn splicing space 7c by a predetermined first set distance D1 or more in a direction opposite to the suction direction of the sac- tion 19. As a result, the yarn in use at the time of knitting is guided to the yarn guide 20 and to the yarn introduction portion 202 that guides the yarn in use discharged from the splicer device 1. When the tension is applied, the yarn is stretched as shown in FIG. 17, and the yarn in use escapes from the yarn splicing space 7c and is positioned in the V-shaped space 7b. As a result, the yarn can be fed smoothly by passing through a wider area than the yarn splicing space 7c.
また図 13に示すように、作用位置に配置される糸案内レバー 14の先端 14aが、糸 継ぎ空間 7cよりも予め定める第 2設定距離 D2以上、サクシヨン 19の吸引方向に離れ るように形成される。これによつて、糸継ぎ時には、使用中の糸は、糸案内レバー 14 の先端 14aによって案内されて、糸継ぎ空間 7cに配置される。同様に選択された糸 もまた、糸案内レバー 14の先端 14aによって案内されて、糸継ぎ空間 7cに配置され る。 Further, as shown in FIG. 13, the tip 14a of the yarn guide lever 14 disposed at the operating position is formed so as to be separated from the yarn splicing space 7c by a predetermined second set distance D2 or more in the suction direction of the sac- tion 19. The As a result, at the time of yarn joining, the yarn in use is guided by the tip 14a of the yarn guide lever 14 and placed in the yarn joining space 7c. Similarly, the selected yarn is also guided by the tip 14a of the yarn guide lever 14 and placed in the yarn splicing space 7c.
これによつて簡単な構造で、糸をガイドすることができる。また糸ガイド 20は、セパレ ータ 15に連なることで、サクシヨン 19近傍に配置することができかつ、スプライスノズ ル 7および糸案内レバー 14に干渉することを防ぐことができる。  Thus, the yarn can be guided with a simple structure. Further, since the yarn guide 20 is connected to the separator 15, it can be arranged in the vicinity of the sac- tion 19 and can be prevented from interfering with the splice nozzle 7 and the yarn guide lever 14.
図 19は、スプライサ装置 1を横編機 60に装着して編糸 61を糸 12として糸継ぎを行 う構成を示す。スプライサ装置 1は、織機やワインダなど、他の装置に装着することも できる。横編機 60は、たとえば、特願 2004— 303761号として提案されてレヽる。図示 を省略しているけれども、横編機 60の上部には、色や性状の異なる複数種類の糸を それぞれ供給可能なコーンが載置される。横編機 60での編地の編成は、ニードルべ ッド 62に配置される編針を、ニードルベッド 62に沿って走行するキャリッジ 63に搭載 されるカム機構で選択的に駆動して行われる。編針に編糸 61を供給するために、キ ャリッジ 63はヤーンフィーダ 64を連行する。横編機 60では、複数のヤーンフィーダ 6 4を選択して編糸 61を切り換えることができるけれども、使用可能なヤーンフィーダ 6 4の数には制限があり、したがって変更可能な編糸 61の数にも制限がある。スプライ サ装置 1で編糸 61を切り換えることができれば、ヤーンフィーダ 64は 1つでも、供給 する編糸 61を複数に切り換えることが可能となり、編成する編地に使用される編糸 6 1の数を大幅に増大させることができる。 FIG. 19 shows a configuration in which the splicer device 1 is mounted on the flat knitting machine 60 and the knitting yarn 61 is used as the yarn 12 for piecing. The splicer device 1 can be attached to other devices such as a loom or a winder. The flat knitting machine 60 is proposed, for example, as Japanese Patent Application No. 2004-303761. Although not shown, a cone capable of supplying a plurality of types of yarns having different colors and properties is placed on the upper portion of the flat knitting machine 60. The knitting of the knitted fabric by the flat knitting machine 60 is performed by selectively driving the knitting needles arranged on the needle bed 62 by a cam mechanism mounted on the carriage 63 that runs along the needle bed 62. The carriage 63 entrains the yarn feeder 64 to supply the knitting yarn 61 to the knitting needle. In the flat knitting machine 60, a plurality of yarn feeders 6 4 can be selected and the knitting yarn 61 can be switched. There is a limit to the number of 4, so there is also a limit to the number of knitting yarns 61 that can be changed. If the splicer device 1 can switch the knitting yarn 61, even one yarn feeder 64 can switch the supplied knitting yarn 61 to a plurality of knitting yarns 61. Can be greatly increased.
編成する編地に編み込まれる編糸 61の長さは、編糸 61の張力変動が少なレ、条件 で予め計算して求めることができる。編成される編地の品質を高めるためにも、急激 な張力変動を避けることが好ましいので、編糸の定量送り出し装置 65が設けられる。 スプライサ装置 1で編糸 61の切換を行うタイミングを、編地で編糸 61を切り換える位 置に合わせるように調整すると、編糸 61の種類を切り換えた糸継ぎ部が編地で編糸 が切り換わる部分付近で編み込まれる。糸継ぎ部が編地の表面から見えないように 編成処理することも可能となる。  The length of the knitting yarn 61 to be knitted in the knitted fabric can be calculated in advance under the conditions where the tension variation of the knitting yarn 61 is small. In order to improve the quality of the knitted fabric to be knitted, it is preferable to avoid sudden tension fluctuations, and therefore a knitting yarn fixed-feed device 65 is provided. When the timing for switching the knitting yarn 61 with the splicer device 1 is adjusted so that it matches the position where the knitting yarn 61 is switched on the knitted fabric, the knitted yarn is cut at the knitted fabric at the spliced portion where the type of the knitting yarn 61 is switched. It is knitted near the changing part. It is also possible to perform knitting so that the yarn splicing portion is not visible from the surface of the knitted fabric.
以上のように、横編機 60側方に装着されるスプライサ装置 1では、ベース 2が複数 の編糸 61の給糸側を上方とし、編糸 61の使用側を下方とする配置で、糸選択部 3を 最上部で、糸選択部 3の下部で第 1モータ 4および第 2モータ 5をそれぞれ支持する ので、選択した編糸 61を下方で継ぐことができる。第 1モータ 4は、糸案内レバー 14 を水平方向の軸を中心として角変位駆動するので、選択した編糸 61を上方で糸案 内レバー 14に引っ掛けて下方に案内することができる。第 2モータ 5は、出力軸が下 方に向力う第 2モータ 5を備えるので、下方で糸継ぎのための駆動を行うことができる 。サクシヨン 19は、スプライスノズノレ 7の溝 7aの出口付近に配置されるので、糸継ぎに よって発生する糸屑を吸引し、除去することができる。  As described above, in the splicer device 1 mounted on the side of the flat knitting machine 60, the base 2 is arranged such that the supply side of the plurality of knitting yarns 61 is the upper side and the use side of the knitting yarn 61 is the lower side. Since the selection unit 3 is supported at the top and the first motor 4 and the second motor 5 are supported at the bottom of the yarn selection unit 3, the selected knitting yarn 61 can be spliced down. Since the first motor 4 angularly drives the yarn guide lever 14 about the horizontal axis, the selected knitting yarn 61 can be hooked on the yarn guide lever 14 upward and guided downward. Since the second motor 5 includes the second motor 5 whose output shaft is directed downward, driving for piecing can be performed below. Since the succession 19 is disposed in the vicinity of the outlet of the groove 7a of the splice nose 7, the yarn waste generated by the splicing can be sucked and removed.
ベース 2は、第 1モータ 4、第 2モータ 5およびサクシヨン 19の下部で、スプライスノズ ル 7を出口が上で入口が下になるように支持するので、使用する編糸 61を下方に引 き出す部分がスプライスノズル 7の入口となって、使用中の編糸 61から選択された編 糸への糸継ぎが終了すると、直ちに使用中の編糸 61を選択された糸に切換えること ができる。  The base 2 supports the splice nozzle 7 at the lower part of the first motor 4, the second motor 5 and the suction 19 so that the outlet is on the upper side and the inlet is on the lower side. When the splicing nozzle 7 becomes the entrance of the splicing nozzle 7 and the splicing from the knitting yarn 61 in use to the selected knitting yarn is completed, the knitting yarn 61 in use can be immediately switched to the selected yarn.
ただし、スプライサ装置 1の動作は、重力の影響をあまり受けないので、各部の配置 は、たとえば上下を逆にして、下方から上方に糸の供給を行うようにすることもできる。 スプライサ装置 1では、複数の糸 12のうちの少なくとも 1本の糸 12bを使用中に、他 の少なくとも 1本の糸 12aに糸継ぎすることが可能である。たとえば 2本の糸 12aを選 択して、使用中の糸 12bとの 3本で糸継ぎすることもできる。糸保持 13は、複数の糸 1 2のうちで使用中ではない糸 12の先端側を保持し、糸選択部 3は、糸保持 13が保持 する糸 12のうちから、糸継ぎする対象となる糸 12aを選択するので、複数の糸 12から 任意の糸 12aを選択して糸継ぎを行うことができる。スプライスノズノレ 7は、糸選択部 3 によって選択される糸 12aと使用中の糸 12bとを、溝 7a内で、圧縮流体の流れで接 合して糸継ぎするので、使用中の糸 12bと選択された糸 12aとは、スプライスノズノレ 7 の入口で連続的に接続される。 However, since the operation of the splicer device 1 is not significantly affected by gravity, the arrangement of each part can be made upside down, for example, so that the yarn is supplied from below to above. In the splicer device 1, while using at least one thread 12b of the plurality of threads 12, It is possible to splice to at least one thread 12a. For example, two yarns 12a can be selected and spliced with three yarns 12b in use. The thread retainer 13 retains the tip end side of the thread 12 that is not in use among the plurality of threads 12, and the thread selection unit 3 is a target to be spliced from the threads 12 retained by the thread retainer 13. Since the yarn 12a is selected, it is possible to perform splicing by selecting an arbitrary yarn 12a from the plurality of yarns 12. The splice nose 7 joins the yarn 12a selected by the yarn selector 3 and the yarn 12b in use by joining the compressed fluid flow in the groove 7a. The selected thread 12a is continuously connected at the inlet of the splice nose 7.
糸案内レバー 14は、糸選択部 3によって選択される糸 12aを先端 14aに引っ掛け て溝 7aの入口まで案内して溝 7aに配置させ、案内のための移動の途中で、使用中 の糸 12bも引っ掛けて溝 7aに案内し、選択された糸 12aとともに溝 7aに配置させる。 糸案内レバー 14は、第 1モータ 4によって駆動される。サクシヨン 19は、溝 7aの出口 付近で糸 12を吸引する。糸クランプ 31は、溝 7aに選択された糸 12aおよび使用中の 糸 12bが嵌まり込んだ状態で、糸継ぎする間、溝 7aの入口を塞くので、圧縮流体が 入口から漏れることを防ぎ、効率良く糸継ぎすることができる。また糸クランプ 31は、 スプライスノズル 7で糸継ぎされる間、溝 7aの入口付近で、使用中の糸 12bと糸選択 部 3で選択された糸 12aとをクランプし、糸継ぎの終了後にクランプを解除するので、 糸継ぎの間は溝 7a内で形成される糸継ぎ部には糸に掛かる張力が作用しないように すること力 Sできる。  The thread guide lever 14 hooks the thread 12a selected by the thread selector 3 to the tip 14a and guides it to the entrance of the groove 7a to place it in the groove 7a. Is also guided to the groove 7a and arranged in the groove 7a together with the selected thread 12a. The yarn guide lever 14 is driven by the first motor 4. Suction 19 sucks thread 12 near the exit of groove 7a. The thread clamp 31 blocks the inlet of the groove 7a during the splicing with the selected thread 12a and the thread 12b being used in the groove 7a fitted, thus preventing the compressed fluid from leaking from the inlet. , Can be spliced efficiently. The thread clamp 31 clamps the thread 12b being used and the thread 12a selected by the thread selector 3 near the entrance of the groove 7a while the splicing nozzle 7 is splicing, and clamps after the splicing is completed. Therefore, during the piecing, it is possible to prevent the tension applied to the yarn from acting on the piecing portion formed in the groove 7a.
カツタ 30は、溝 7aの出口付近で、糸継ぎする使用中の糸 12bと選択された糸 12aと を切断するので、形成される糸継ぎ部の長さを制限することができる。第 2モータ 5は 、カツタ 30および糸クランプ 31を、糸案内レバー 14を駆動する第 1モータ 4とは個別 に設けられるので、カツタ 30および糸クランプ 31を、糸案内レバー 14とは独立して制 御すること力 Sでき、たとえば弱い糸では糸案内レバー 14を低速で角変位させ、他の 機構は通常速度で動かすなどのように、制御の柔軟性を得ることができる。  The cutter 30 cuts the used yarn 12b to be spliced and the selected yarn 12a near the outlet of the groove 7a, so that the length of the spliced portion to be formed can be limited. Since the second motor 5 is provided with the cutter 30 and the thread clamp 31 separately from the first motor 4 that drives the thread guide lever 14, the cutter 30 and the thread clamp 31 are provided independently of the thread guide lever 14. The control force S can be obtained. For example, with a weak yarn, the yarn guide lever 14 is angularly displaced at a low speed, and other mechanisms can be moved at a normal speed.
ベース 2は、糸保持 13、糸選択部 3、スプライスノズノレ 7、糸案内レバー 14、第 1モ ータ 4、サクシヨン 19、カツタ 30、および第 2モータ 5を含む、各部を、相互の位置関 係を保つように支持するので、各部を所要スペースが小さくなるように配置して、各部 をコンパクトに支持し、装置を小型化することができる。し力もベース 2は、隔壁 100を 有しているので、糸保持 13、スプライスノズル 7、糸案内レバー 14、カツタ 30、サクシ ヨン 19および糸ガイド 20などが設けられる隔壁 100の手前側で、糸継ぎによって発 生する繊維塵が、第 1および第 2モータ 4, 5ならびに第 1および第 2電磁弁ユニット 1 30, 131の配置される隔壁 100の奥側に飛散することを抑制することができる。した 力 Sつて第 1および第 2モータ 4, 5ならびに第 1および第 2電磁弁ユニット 130, 131に 繊維塵が嚙み込むことによる動作不良を防ぐことができる。このように好適なスプライ サ装置 1を実現することができる。し力も電磁弁が組み込まれたスプライサ装置 1を実 現すること力 Sできる。 Base 2 includes thread retainer 13, thread selector 3, splice nose 7, thread guide lever 14, first motor 4, succession 19, cutter 30, and second motor 5. Since it is supported so as to maintain the relationship, each part is arranged so that the required space is reduced. Can be compactly supported, and the apparatus can be miniaturized. Since the base 2 has the partition wall 100, the thread holding 13, the splice nozzle 7, the thread guide lever 14, the cutter 30, the suction 19 and the thread guide 20 are provided on the front side of the partition 100. The fiber dust generated by the splicing can be prevented from scattering to the back side of the partition wall 100 where the first and second motors 4 and 5 and the first and second solenoid valve units 1 30 and 131 are disposed. . Therefore, it is possible to prevent malfunction caused by the stagnation of fiber dust into the first and second motors 4, 5 and the first and second solenoid valve units 130, 131. Thus, a suitable splicer device 1 can be realized. The force S can be realized by realizing the splicer device 1 in which the solenoid valve is incorporated.
また第 1モータ 4の出力軸と、糸案内レバー 14の角変位軸とが平行であるので、第 1モータ 4によって糸案内レバー 14を駆動するために要するスペースを低減すること ができる。糸案内レバーは、予め定める角度範囲内で角変位可能であり、糸案内レ バーを角変位させるために必要な空間も、予め定める角度範囲内に制限することが でき、糸案内レバーを設けるために必要な空間を低減することができる。またカツタ 3 0および糸クランプ 31は、カム機構を介して、第 2モータ 5で駆動される。したがって力 ッタ 30および糸クランプ 31を、その動作を同期させて駆動することができる。  Further, since the output shaft of the first motor 4 and the angular displacement axis of the yarn guide lever 14 are parallel, the space required for driving the yarn guide lever 14 by the first motor 4 can be reduced. The thread guide lever can be angularly displaced within a predetermined angle range, and the space necessary for angularly displacing the thread guide lever can also be limited within the predetermined angle range, and the thread guide lever is provided. It is possible to reduce the space required for the operation. The cutter 30 and the thread clamp 31 are driven by the second motor 5 through a cam mechanism. Therefore, the force cutter 30 and the thread clamp 31 can be driven with their operations synchronized.

Therefore, the above-described embodiment is merely an example in all respects, and the scope of the present invention is shown in the claims, and is not restricted by the text of the specification. Further, all modifications and changes belonging to the scope of claims are within the scope of the present invention.

Can be Since the base has a partition wall, the fiber dust generated by the yarn joining on the one side of the partition wall on which the holding section, head section, thread guide lever, cutter, and suction are provided is the first and first. 2 Scattering to the other side of the partition wall where the drive unit is disposed can be suppressed. Therefore, it is possible to prevent malfunction due to fiber dust trapped in the first and second drive units.
本発明によれば、ヘッドへの圧縮流体の供給および供給停止を制御する供給制御 用電磁弁と、サクションによる糸の吸引および吸引停止を制御する吸弓 I制御用電磁 弁とが組み込まれる。これらの供給制御用電磁弁および吸引制御用電磁弁は、隔壁 の他方側に配置されるので、供給制御用電磁弁および吸引制御用電磁弁に繊維塵 が嚙み込むことによる動作不良を防ぐことができる。したがって供給制御用電磁弁お よび吸引制御用電磁弁が組み込まれる好適なスプライサ装置が実現される。  According to the present invention, the supply control solenoid valve for controlling the supply and stop of supply of the compressed fluid to the head and the sucking bow I control solenoid valve for controlling the suction and stoppage of the yarn by the suction are incorporated. Since these supply control solenoid valve and suction control solenoid valve are arranged on the other side of the partition wall, it is possible to prevent malfunction caused by fiber dust trapped in the supply control solenoid valve and suction control solenoid valve. Can do. Therefore, a suitable splicer device in which the supply control solenoid valve and the suction control solenoid valve are incorporated is realized.
本発明によれば、保持部制御用電磁弁によって、保持部への圧縮流体の供給およ び供給停止が制御される。保持部を制御するための保持部制御用電磁弁は、隔壁 の他方側に配置されので、保持部制御用電磁弁に繊維塵が嚙み込むことによる動 作不良を防ぐことができる。したがって保持部を圧縮流体によって駆動する構成とし、 保持部を制御するための保持部制御用電磁弁が組み込まれる好適なスプライサ装 置が実現される。  According to the present invention, the supply and stop of supply of the compressed fluid to the holding unit are controlled by the holding unit control electromagnetic valve. Since the holding unit control solenoid valve for controlling the holding unit is arranged on the other side of the partition wall, it is possible to prevent malfunction due to fiber dust swallowing into the holding unit control solenoid valve. Therefore, a suitable splicer device is realized in which the holding unit is driven by the compressed fluid and the holding unit control electromagnetic valve for controlling the holding unit is incorporated.
本発明によれば、糸クランプが、第 2駆動部によって駆動され、選択された糸と使用 中の糸とがヘッドの溝に嵌まり込んだ状態で、ヘッドの溝の入口を塞ぐので、ヘッドの 溝内で糸継ぎする圧縮流体が入口から漏れるのを抑えて、糸継ぎを効率的に行うこ とができる。さらに糸クランプによって、選択された糸と使用中の糸とをクランプするこ とができるので、選択された糸と使用中の糸とをヘッドの溝に嵌まり込ませた状態でし つかりと保持し、糸継ぎ不良を防ぐことができる。  According to the present invention, the yarn clamp is driven by the second drive unit, and the selected yarn and the yarn in use are fitted in the groove of the head, thereby closing the inlet of the head groove. It is possible to efficiently perform the piecing by suppressing the compressed fluid piecing in the groove from leaking from the inlet. Furthermore, since the selected thread and the thread in use can be clamped by thread clamping, the selected thread and the thread in use are held firmly in the state where they are fitted in the groove of the head. In addition, it is possible to prevent defective splicing.
本発明によれば、糸ガイドの案内面が、ヘッドの溝力 溝深さ方向に脱出した位置 に配置される。したがって使用中の糸にテンションが与えられることで、糸が張られて 、ヘッドの溝に糸が嵌り込んだ状態となることを防ぐことができる。これによつて、円滑 な編成動作を実現することができる。また糸ガイドは、ベースに対して固定式とするこ とができ、構造を簡単化することができる。また糸ガイドを駆動させる必要がないので 、スプライサ装置の構造を簡単化することができる。また糸ガイドを駆動するための駆 動源からの動力を伝達する貫通孔をベースに形成する必要がなぐ繊維塵などがベ ース奥側に侵入することを防いで、駆動部の動作不良を防ぐことができる。 According to the present invention, the guide surface of the yarn guide is disposed at a position where it has escaped in the groove depth direction of the head. Therefore, tension is applied to the thread in use, and the thread is stretched. The thread can be prevented from being fitted into the groove of the head. As a result, a smooth knitting operation can be realized. Further, the thread guide can be fixed to the base, and the structure can be simplified. In addition, since it is not necessary to drive the yarn guide, the structure of the splicer device can be simplified. In addition, it prevents fiber dust that does not need to be formed in the base from a through hole that transmits power from the drive source for driving the thread guide, and prevents the drive unit from malfunctioning. Can be prevented.
本発明によれば、ベースは、複数の糸の給糸側と糸の使用側とを結ぶ方向に延び る隔壁を有している。ベースの端部のうち糸の給糸側の端部に選択部が配置され、 その選択部から糸の使用側に、保持部、サクシヨン、カツタおよびヘッド、ならびに第 1および第 2駆動部が配置され、選択部で選択された糸が、その選択部から糸の使 用側で使用中の糸に糸継される。さらに保持部から、サクシヨン、カツタおよびヘッド の順で、糸の給糸側から糸の使用側に向かって並び、ヘッドは、溝の出口が糸の給 糸側となり、溝の入口が糸の使用側となるように配置されている。したがって使用中の 糸から選択された糸への糸継ぎが終了すると、直ちに使用中の糸を選択された糸に 切換えることができるとともに、選択された糸のカツタによって切除される不要部分を サクシヨンによって吸引することができる。  According to the present invention, the base has the partition wall extending in the direction connecting the yarn supply side of the plurality of yarns and the yarn use side. A selection unit is arranged at the end of the base on the yarn supply side, and a holding unit, a sac- tion, cutter and head, and first and second drive units are arranged from the selection unit to the yarn usage side. Then, the yarn selected by the selection unit is spliced from the selection unit to the yarn being used on the yarn use side. Furthermore, from the holding part, in the order of succession, cutter, and head, the yarns are lined up from the yarn supply side to the yarn usage side, and the head has a groove outlet at the yarn supply side and a groove entrance at the yarn use side. It is arranged to be on the side. Therefore, as soon as the splicing from the currently used thread to the selected thread is completed, the currently used thread can be switched to the selected thread, and unnecessary portions that are cut off by the cutter of the selected thread can be removed by the succinction. Can be aspirated.
本発明によれば、第 1駆動部であるモータの出力軸と、糸案内レバーの角変位軸と が平行であるので、モータの出力軸で糸案内レバーを直接駆動したり、歯車などの 伝達機構を介して駆動する場合に、要するスペースを低減することができる。糸案内 レバーは、予め定める角度範囲内で角変位可能であり、糸案内レバーを角変位させ るために必要な空間も、予め定める角度範囲内に制限することができ、糸案内レバ 一を設けるために必要な空間を低減することができる。  According to the present invention, since the output shaft of the motor, which is the first drive unit, and the angular displacement shaft of the yarn guide lever are parallel, the yarn guide lever is directly driven by the motor output shaft or the transmission of gears, etc. When driving through a mechanism, the required space can be reduced. The thread guide lever is angularly displaceable within a predetermined angle range, and the space required for angular displacement of the thread guide lever can also be limited within the predetermined angle range, and a thread guide lever is provided. Therefore, it is possible to reduce the space required for this.
本発明によれば、カツタおよび糸クランプは、カム機構を介して、第 2駆動部である モータで駆動される。したがってカツタおよび糸クランプを、その動作を同期させて駆 動すること力 Sできる。  According to the present invention, the cutter and the thread clamp are driven by the motor that is the second drive unit via the cam mechanism. Therefore, it is possible to drive the cutter and the thread clamp with their movements synchronized.
