Description

本発明は、線材が巻回された複数のスプールからそれぞれ巻解かれた線材を撚って撚り線を得る線材撚り装置及び撚り線の製造方法に関するものである。   The present invention relates to a wire twisting device that twists a wire wound from a plurality of spools around which the wire is wound to obtain a stranded wire, and a method for manufacturing a stranded wire.

従来、線材が巻回された複数のスプールから線材をそのスプールの軸方向にそれぞれ引き出し、それら複数のスプールを公転させてそれらからそれぞれ巻解かれた線材を撚って撚り線を製造する装置が知られている(例えば、特許文献1参照。)。   Conventionally, there is an apparatus for producing a stranded wire by drawing a wire from a plurality of spools around which the wire is wound, in the axial direction of the spool, revolving the plurality of spools, and twisting the unwound wire from each spool. It is known (for example, refer to Patent Document 1).

特開2001−76556号公報JP 2001-76556 A

しかし、スプールから線材をそのスプールの軸方向に引き出すと、その引き出された線材は捩られた状態で引き出されることに成り、このように、既に捩られた複数の線材を撚って撚り線を製造すると、線材が既に捩られていることから、得られた撚り線の撚りの程度が、その後に各線材の弾性により戻ってしまい、所望の撚り状態を維持できないような事態を生じさせる。   However, when the wire rod is pulled out from the spool in the axial direction of the spool, the drawn wire rod is pulled out in a twisted state, and in this way, a plurality of already twisted wire rods are twisted to form a stranded wire. When manufactured, since the wire has already been twisted, the degree of twisting of the obtained stranded wire is then returned by the elasticity of each wire, causing a situation in which the desired twisted state cannot be maintained.

また、複数のスプールから線材をそのスプールの軸方向に引き出すと、各スプールから繰り出された線材における捩りの程度が異なることもある。このように捩りの程度が異なる複数の線材を撚ると、撚り線を構成する各線材の弾性により戻ろうとする復元力が異なることに成り、得られた撚り線の撚りの程度が局部的に異なり、撚りの程度が均一な撚り線を得ることが困難になる不具合も生じさせる。   Further, when the wire rod is pulled out from a plurality of spools in the axial direction of the spool, the degree of twist in the wire rod fed out from each spool may be different. When twisting a plurality of wires having different degrees of twisting in this way, the restoring force to return due to the elasticity of each wire constituting the stranded wire is different, and the degree of twist of the obtained stranded wire is locally In contrast, it also causes a problem that it is difficult to obtain a stranded wire with a uniform degree of twist.

この様な不具合を解消するためには、線材をスプールの円周方向に引き出して、捩られていない状態で、複数の線材を撚ることが考えられる。けれども、線材をスプールの円周方向に引き出す為には、スプールを回転させなければならず、スプールに貯線された線材の巻回された直径は、線材が引き出される従って小さくなり、スプールの回転速度が一定であってもその周方向に引き出される線材の速度は変動し、常に一定の速度で線材を繰り出すことが困難に成る不具合があった。   In order to solve such a problem, it is conceivable to pull out the wire in the circumferential direction of the spool and twist the plurality of wires in a state where the wire is not twisted. However, in order to pull out the wire in the circumferential direction of the spool, the spool must be rotated, and the wound diameter of the wire stored in the spool becomes smaller as the wire is pulled out, and the spool rotates. Even if the speed is constant, the speed of the wire drawn in the circumferential direction fluctuates, and there is a problem that it is difficult to always feed the wire at a constant speed.

また、引き出す線材の速度に変動が生じる場合、スプールの回転速度が、その変動に追従できなければ、線材を所望の速度で引き出すことができずに、比較的細い線材にあっては、速度変動に追従できない線材が引き千切られるような事態も生じさせる。   Also, when fluctuations occur in the speed of the drawn wire, if the spool rotation speed cannot follow the fluctuation, the wire cannot be drawn out at the desired speed. It also causes a situation where the wire rod that cannot follow is broken.

本発明の目的は、複数のスプールから線材を所望の速度で捩ることなく引き出して、捩られていない複数の線材を撚ることのできる線材撚り装置及び撚り線の製造方法を提供することにある。   An object of the present invention is to provide a wire twisting device and a method of manufacturing a twisted wire that can draw a wire from a plurality of spools without twisting at a desired speed and twist a plurality of untwisted wires. .

本発明は、スプールから巻解かれて繰り出される線材が挿通される複数のノズルが先端に設けられた軸部材と、制御手段により制御され軸部材の中心軸を回転中心として軸部材を回転させる軸部材回転手段と、回転軸が軸部材と平行になるように軸部材の周囲に設けられ軸部材の回転により軸部材を中心として公転する複数の公転体と、公転体の自転を禁止する自転禁止手段と備え、軸部材とともに回転する複数のノズルから繰り出された複数の線材を撚る線材撚り装置である。   The present invention relates to a shaft member provided with a plurality of nozzles at the tip thereof through which a wire rod unwound from a spool is inserted, and a shaft that is controlled by the control means and rotates the shaft member around the center axis of the shaft member A member rotating means, a plurality of revolution bodies provided around the shaft member so that the rotation shaft is parallel to the shaft member, and revolving around the shaft member by rotation of the shaft member, and rotation prohibition prohibiting rotation of the revolution body A wire twisting device that twists a plurality of wire rods fed from a plurality of nozzles that rotate together with the shaft member.

その特徴ある構成は、スプールが回転して線材を巻解くようにスプールの中心軸を軸部材の中心軸に直交する面内にしてスプールが公転体に枢支され、制御手段により制御されスプールを回転させる回転駆動手段が公転体に設けられたところにある。   The characteristic configuration is that the spool is pivotally supported by the revolution body with the central axis of the spool in a plane perpendicular to the central axis of the shaft member so that the spool rotates and unwinds the wire, and is controlled by the control means. The rotating drive means for rotating is provided at the revolution body.

この場合、回転駆動手段がスプールに並列に設けられたモータであることが好ましく、そのモータは、軸部材が同軸に連結された一対の小モータから成ることが更に好ましい。   In this case, the rotation driving means is preferably a motor provided in parallel with the spool, and the motor is more preferably composed of a pair of small motors whose shaft members are connected coaxially.

一方、スプールから供給される線材に張力を付与する張力付与手段が設けられ、制御手段は、張力付与手段により付与される張力が一定となるようにスプールの回転を制御することが好ましく、張力付与手段は、回動支点の回りで回動可能なテンションアームと、テンションアームの先端に取り付けられスプールからノズルに延びる線材が掛け回される線材ガイドと、テンションアームの回動支点と線材ガイドとの間の所定位置においてテンションアームにその回動角度に応じた弾性力を及ぼす弾性部材と、テンションアームの回動角度を検出する検出手段とを備え、制御手段は、検出手段により検出された回動角度が所定の角度となるように回転駆動手段を制御することが更に好ましい。   On the other hand, tension applying means for applying tension to the wire supplied from the spool is provided, and the control means preferably controls the rotation of the spool so that the tension applied by the tension applying means is constant. The means includes a tension arm that is rotatable around a rotation fulcrum, a wire guide that is attached to the tip of the tension arm and that is wound around a wire extending from the spool to the nozzle, and the rotation fulcrum of the tension arm and the wire guide. An elastic member that exerts an elastic force on the tension arm according to the rotation angle at a predetermined position, and a detection unit that detects the rotation angle of the tension arm, and the control unit detects the rotation detected by the detection unit. More preferably, the rotation driving means is controlled so that the angle becomes a predetermined angle.

そして、軸部材の中心軸に芯線が通過する芯線通路が形成され、軸部材の基端側から芯線通路に芯線を供給する芯線供給機を更に備え、軸部材の先端から繰り出された芯線の周囲に複数のノズルから繰り出された線材を螺旋状に巻き付けるように構成することもできる。   A core wire passage through which the core wire passes is formed in the central axis of the shaft member, and further includes a core wire feeder for supplying the core wire from the proximal end side of the shaft member to the core wire passage, and around the core wire fed out from the tip end of the shaft member In addition, the wire rod fed out from the plurality of nozzles may be wound in a spiral shape.

一方、別の本発明は、複数のスプールを軸部材を中心として公転させ、複数のスプールからそれぞれ巻き解かれて繰り出される複数の線材が撚られた撚り線を得る撚り線の製造方法である。   On the other hand, another aspect of the present invention is a method of manufacturing a stranded wire that revolves a plurality of spools around a shaft member and obtains a stranded wire in which a plurality of wire rods unwound from the plurality of spools and twisted are twisted.

その特徴ある点は、軸部材の回転により軸部材を中心として公転する複数の公転体を設け、スプールが回転して線材を巻解くようにスプールの中心軸を軸部材の中心軸に直交する面内にしてスプールを公転体に枢支させ、スプールを回転させる回転駆動手段を公転体に設け、複数の公転体の自転を禁止しつつ軸部材を中心として複数の公転体を公転させ、スプールから巻き解かれた線材の張力が一定となるようにスプールの回転を制御しつつ公転体を公転させて複数の公転体にそれぞれ設けられた複数のスプールからそれぞれ巻き解かれて繰り出される複数の線材を撚るところにある。   The characteristic point is that a plurality of revolution bodies that revolve around the shaft member are provided by the rotation of the shaft member, and the center axis of the spool is perpendicular to the center axis of the shaft member so that the spool rotates and unwinds the wire. The spool is pivotally supported on the revolution body, and a rotation drive means for rotating the spool is provided on the revolution body, and the revolution bodies are revolved around the shaft member while prohibiting the rotation of the revolution bodies. While controlling the rotation of the spool so that the tension of the unwound wire is constant, the revolving body is revolved, and a plurality of wires that are unwound from each of the plurality of spools provided on the plurality of revolving bodies are drawn out. It is in a place to twist.

軸部材の中心軸に芯線が通過する芯線通路を形成している場合、公転体を公転させつつ軸部材の基端側から芯線通路に芯線を供給し、軸部材の先端から繰り出された芯線の周囲に線材を螺旋状に巻き付けることもできる。   When the core wire passage through which the core wire passes is formed in the central axis of the shaft member, the core wire is supplied to the core wire passage from the base end side of the shaft member while revolving the revolving body, and the core wire fed out from the tip end of the shaft member A wire rod can also be wound around the periphery.

本発明の線材撚り装置及び撚り線の製造方法では、スプールの中心軸を軸部材の中心軸に直交する面内にしてスプールを公転体に枢支したので、回転駆動手段によりスプールを回転させて線材を巻解くことにより、その線材を軸部材の長手方向に所望の速度で引き出すことができる。すると、線材はスプールの円周方向に引き出され、その引き出しの際に線材が捩られるようなことはない。よって、本発明では、複数のスプールから線材を所望の速度で捩ることなく引き出して撚ることのできるものとなる。   In the wire stranding device and the method for manufacturing a stranded wire according to the present invention, the spool is pivotally supported on the revolution body with the center axis of the spool being in a plane perpendicular to the center axis of the shaft member. By unwinding the wire, the wire can be drawn out at a desired speed in the longitudinal direction of the shaft member. Then, the wire is drawn out in the circumferential direction of the spool, and the wire is not twisted during the drawing. Therefore, in the present invention, the wire can be drawn and twisted from a plurality of spools without twisting at a desired speed.

そして、回転駆動手段がスプールに並列に設けられたモータであれば、そのモータをスプールの軸方向に設ける場合に比較して、公転体の幅方向の寸法を小さくすることができ、公転体の幅方向の寸法が拡大することに起因する公転半径の拡大は防止され、公転半径の拡大に起因する装置の大型化を回避することができる。   If the rotation driving means is a motor provided in parallel with the spool, the dimension of the revolution body in the width direction can be reduced as compared with the case where the motor is provided in the axial direction of the spool. An increase in the revolution radius due to the increase in the dimension in the width direction is prevented, and an increase in the size of the apparatus due to the increase in the revolution radius can be avoided.

また、そのモータは、軸部材が同軸に連結された一対の小モータから成る様であれば、同一の動力であるにもかかわらず、単一のモータによりスプールを回転させる場合に比較して、モータの径方向の寸法を小さくすることができ、そのモータが設けられる公転体の回転軸方向における寸法を小さくすることもできる。   In addition, if the motor is composed of a pair of small motors whose shaft members are coaxially connected, the motor is the same power, but compared to the case where the spool is rotated by a single motor, The dimension in the radial direction of the motor can be reduced, and the dimension in the rotation axis direction of the revolution body provided with the motor can also be reduced.

そして、複数のスプールから別々に巻解かれた複数の線材に別々に所定の張力を加える複数の張力付与手段を設ければ、各ノズルから繰出される線材のそれぞれの張力は略等しくなり、その張力変動を押さえて、所定のピッチで規則正しく撚られた複数の線材から成る撚り線を得ることができる。   Then, if a plurality of tension applying means for applying a predetermined tension separately to a plurality of wire rods separately unwound from a plurality of spools are provided, the respective tensions of the wire rods fed from the nozzles are substantially equal, It is possible to obtain a stranded wire composed of a plurality of wire rods regularly twisted at a predetermined pitch while suppressing tension fluctuation.

一方、スプールに貯線された線材の巻回された直径は、線材が引き出される従って小さくなり、スプールの回転速度が一定であれば、その周方向に引き出される線材の速度は変動することになる。けれども、引き出される線材の速度変動は、線材の張力に影響を与えるので、張力付与手段によりその線材に付与される張力が一定となるようにスプールの回転を制御すれば、スプールに巻回された線材の外径が変化した場合でも、そのスプールから引き出される線材の速度を目標値に保つことができ、その速度が変動するような事態を回避することができる。   On the other hand, the wound diameter of the wire rod stored in the spool becomes smaller as the wire rod is pulled out, and if the rotation speed of the spool is constant, the speed of the wire rod drawn in the circumferential direction will fluctuate. . However, since the speed fluctuation of the drawn wire affects the tension of the wire, if the rotation of the spool is controlled so that the tension applied to the wire is constant by the tension applying means, the wire is wound around the spool. Even when the outer diameter of the wire changes, the speed of the wire drawn from the spool can be maintained at the target value, and a situation in which the speed fluctuates can be avoided.

よって、スプールの回転速度が繰り出される線材の速度変動に追従できないような事態は回避され、線材を所望の速度で引き出すことができない場合に生じる線材が引き千切られるような事態を回避することができる。   Therefore, a situation in which the rotation speed of the spool cannot follow the speed fluctuation of the wire that is fed out is avoided, and a situation in which the wire that occurs when the wire cannot be pulled out at a desired speed can be avoided. .

The wire twisting device 10 of the present invention includes a shaft member 11 and shaft member rotating means 12 that rotates the shaft member 11 around the central axis of the shaft member 11 as a rotation center. The shaft member 11 is a rod-shaped member having a circular cross section, and a core wire passage 11 a through which the core wire 13 passes is formed at the central axis of the shaft member 11. A plurality of nozzles 11b, through which a wire 32 unwound from a spool 31 (described later) is fed, are inserted at the tip of the shaft member 11 radially at equal angles around the core wire passage 11a (FIG. 5). .

この実施の形態におけるノズル11bは、軸部材11の先端に芯線通路11aと平行に形成された孔であって、図5に示すように、この孔から成るノズル11bは、芯線通路11aを中心に60度毎に6個形成される場合を示す。   The nozzle 11b in this embodiment is a hole formed in the tip of the shaft member 11 in parallel with the core wire passage 11a. As shown in FIG. 5, the nozzle 11b made of this hole is centered on the core wire passage 11a. The case where 6 pieces are formed every 60 degrees is shown.

図1に戻って、軸部材11は、その基端側端縁と先端側端縁がベアリング14a,15aを介してそれぞれ台板14,15に枢支され、軸部材11が水平になるように台板14,15が基台16に立設される。基台16には、この基台16を移動可能な複数のローラ16aと、この基台16を設置可能な複数の支持脚16bとが設けられる。   Returning to FIG. 1, the shaft member 11 has its proximal end edge and distal end edge supported on the base plates 14 and 15 via bearings 14 a and 15 a, respectively, so that the shaft member 11 is horizontal. The base plates 14 and 15 are erected on the base 16. The base 16 is provided with a plurality of rollers 16a capable of moving the base 16 and a plurality of support legs 16b on which the base 16 can be installed.

基端側台板14には、軸部材回転手段12を構成するサーボモータ12aがその回転軸12bが軸部材11と平行になるように設けられ、その回転軸12bには第一プーリ12cが設けられる。その第一プーリ12cに対応する軸部材11の基端側には第二プーリ12dが設けられ、第一プーリ12cと第二プーリ12dの間にはベルト12eが掛け回される。サーボモータ12aには、制御手段であるコントローラ8の制御出力が接続され、そのコントローラ8からの指令によりサーボモータ12aが駆動してその回転軸12bが第一プーリ12cとともに回転すると、その回転はベルト12eにより第二プーリ12dに伝達され、その第二プーリ12dが設けられた軸部材11が芯線通路11aを回転中心として回転するように構成される。   The proximal base plate 14 is provided with a servo motor 12a constituting the shaft member rotating means 12 so that the rotary shaft 12b is parallel to the shaft member 11, and the first pulley 12c is provided on the rotary shaft 12b. It is done. A second pulley 12d is provided on the base end side of the shaft member 11 corresponding to the first pulley 12c, and a belt 12e is wound between the first pulley 12c and the second pulley 12d. The servo motor 12a is connected to the control output of the controller 8 which is a control means. When the servo motor 12a is driven by the command from the controller 8 and the rotation shaft 12b rotates together with the first pulley 12c, the rotation is the belt. 12e is transmitted to the second pulley 12d, and the shaft member 11 provided with the second pulley 12d is configured to rotate around the core wire passage 11a.

軸部材11には、その中心軸方向に所定の間隔を開けて一対の支持板21,22が設けられ、この一対の支持板21,22には複数の公転体23が枢支される(図1には二台の公転体23を示す)。この複数の公転体23は、それらの回転軸C2が軸部材11の中心軸C1と平行になるよう一対の支持板21,22に枢支され、この実施の形態では、ノズル11bの数に等しい6個の公転体23が設けられるものとする(図4及び図5)。   The shaft member 11 is provided with a pair of support plates 21 and 22 at a predetermined interval in the central axis direction, and a plurality of revolution bodies 23 are pivotally supported on the pair of support plates 21 and 22 (see FIG. 1 shows two revolution bodies 23).

It is assumed that six revolution bodies 23 are provided (FIGS. 4 and 5).

複数の公転体23はそれぞれ同一構造であるので、その内の1つを代表して説明する。すると、図3に示すように、この公転体23は、その平面視において、軸部材11の基端側に位置する方形部23aと、軸部材11の先端側に位置する台形部23bとから成り、それらの回転軸C2上における両端には円筒状の枢支部材23c,23dがそれぞれ設けられ、これらの枢支部材23c,23dが一対の支持板21,22にベアリング21a,22aを介してそれぞれ枢支される。このようにして、この複数の公転体23は、その回転軸C2が軸部材11と平行になるように支持板21,22に枢支され、軸部材11の回転によりその軸部材11を中心として公転するように構成される。   Since the plurality of revolution bodies 23 have the same structure, one of them will be described as a representative. Then, as shown in FIG. 3, the revolution body 23 includes a rectangular portion 23 a located on the proximal end side of the shaft member 11 and a trapezoidal portion 23 b located on the distal end side of the shaft member 11 in the plan view. Cylindrical pivot members 23c and 23d are respectively provided at both ends on the rotation axis C2, and these pivot members 23c and 23d are respectively connected to the pair of support plates 21 and 22 through bearings 21a and 22a.

Configured to revolve.

図1に戻って、この線材撚り装置10には、公転体23の自転を禁止する自転禁止手段25が設けられる。図4に示すように、この実施の形態における自転禁止手段25は、公転体23の基端側枢支部材23cに公転体23の回転軸C2と同軸に設けられた第一スプロケット26と、第一スプロケット26と同形同大であって軸部材11と同軸になるように基端側台板14(図1)に回転不能に取付けられた第二スプロケット27と、この第一及び第二スプロケット27を連結するチェーン28とを備える。ここで、符号27aは、第二スプロケット27を基端側台板14(図1)に取付ける取付脚27aである。   Returning to FIG. 1, the wire twisting device 10 is provided with a rotation prohibiting means 25 that prohibits the rotation of the revolution body 23.

The connector 47 for connecting with the motor 40 etc. which were provided in the revolution body 23 revolving around is shown.

図2及び図3に示すように、公転体23における方形部23aと台形部23bの境には、その方形部23aに設けられたスプール31から巻解かれた線材32を挟んで公転体23の幅方向(スプール31の中心軸C3方向)における中央に集める一対のローラ51,51が枢支され、その台形部23bには、一対のローラ51,51により案内された線材32を軸部材11の先端側支持板22に枢支された枢支部材23dに貫通させるように案内する複数のプーリ52,52が枢支される。   As shown in FIG. 2 and FIG. 3, the revolution body 23 has a boundary between the rectangular portion 23a and the trapezoidal portion 23b with a wire 32 unrolled from a spool 31 provided in the square portion 23a. A pair of rollers 51, 51 gathered at the center in the width direction (the direction of the central axis C3 of the spool 31) is pivotally supported, and a wire rod 32 guided by the pair of rollers 51, 51 is attached to the trapezoidal portion 23b of the shaft member 11. A plurality of pulleys 52, 52 that are guided so as to penetrate through a pivot member 23 d that is pivotally supported by the distal end side support plate 22 are pivotally supported.

そして、図2に示すように、これら一対のローラ51,51及びプーリ52,52は、公転体23の表面側と裏面側(図2の上側と下側)の双方に取付けられ、スプール31に巻回された線材32を公転体23の表面側と裏面側のいずれに側に巻解いても、そのように巻解かれた線材32を軸部材11の先端側支持板22に枢支された枢支部材23dにそれぞれ貫通させ得るように構成される。   As shown in FIG. 2, the pair of rollers 51, 51 and pulleys 52, 52 are attached to both the front surface side and the back surface side (upper side and lower side in FIG. 2) of the revolution body 23. Regardless of whether the wound wire rod 32 is unwound on either the front surface side or the back surface side of the revolving member 23, the unrolled wire rod 32 is pivotally supported by the front end side support plate 22 of the shaft member 11. Each of the pivot members 23d can be penetrated.

スプール31から巻解かれて先端側支持板22に枢支された枢支部材23dを貫通した線材32はその後ノズル11b(図1)にまで案内されるけれども、図5に示すように、この先端側支持板22には、スプール31から供給される線材32に張力を付与する張力付与手段60が設けられる。   The wire 32 that is unwound from the spool 31 and passes through the pivot member 23d pivotally supported by the distal support plate 22 is then guided to the nozzle 11b (FIG. 1), but as shown in FIG. The side support plate 22 is provided with tension applying means 60 for applying tension to the wire 32 supplied from the spool 31.

この実施の形態における張力付与手段60は、その先端側支持板22に設けられ回動支点の回りで回動可能なテンションアーム61と、そのテンションアーム61の先端に取り付けられスプール31(図2)から枢支部材23dを貫通してノズル11bにまで延びる線材32が掛け回される線材ガイド62と、そのテンションアーム61の回動支点と線材ガイド62との間の所定位置においてテンションアーム61にその回動角度に応じた弾性力を及ぼす弾性部材63と、テンションアーム61の回動角度を検出する検出手段64とを備える。   The tension applying means 60 in this embodiment includes a tension arm 61 provided on the distal end side support plate 22 and rotatable around a rotation fulcrum, and a spool 31 attached to the distal end of the tension arm 61 (FIG. 2). To the tension arm 61 at a predetermined position between the wire rod guide 62 through which the wire rod 32 extending through the pivot member 23d to the nozzle 11b is wound, and the pivot fulcrum of the tension arm 61 and the wire rod guide 62. An elastic member 63 that exerts an elastic force according to the rotation angle and a detection means 64 that detects the rotation angle of the tension arm 61 are provided.

即ち、スプール31から巻解かれて枢支部材23dを貫通した線材32はテンションアーム61の先端における線材ガイド62に導かれる。このため先端側支持板22には枢支部材23dを貫通した線材32を軸部材11に向かわせる第一転向プーリ66と、その軸部材11に向かう線材32を横方向に折り返して先端側支持板22の周方向に向かわせる第二転向プーリ67が設けられる。   That is, the wire 32 unwound from the spool 31 and penetrates the pivot member 23 d is guided to the wire guide 62 at the tip of the tension arm 61. For this reason, the front end side support plate 22 has a first turning pulley 66 for directing the wire 32 penetrating the pivot member 23d toward the shaft member 11, and the wire 32 toward the shaft member 11 is folded back in the lateral direction to return the front end side support plate. A second turning pulley 67 is provided to be directed in the circumferential direction of 22.

第二転向プーリ67により先端側支持板22の周方向に転向した線材32が線材ガイド62に達するように、その線材ガイド62が先端に設けられたテンションアーム61は支持板22の直径方向に延びて設けられる。線材ガイド62に導かれた線材32はその線材ガイド62に掛け回されて折り返され、支持板22の逆の周方向に向かい、その逆の周方向に向かう線材32を再び軸部材11に向かわせるように転向させる第三転向プーリ68が支持板22に設けられる。   The tension arm 61 provided with the wire rod guide 62 at the tip extends in the diameter direction of the support plate 22 so that the wire rod 32 turned in the circumferential direction of the tip support plate 22 by the second turning pulley 67 reaches the wire guide 62. Provided. The wire rod 32 guided to the wire rod guide 62 is looped around the wire rod guide 62 and turned back, and is directed to the opposite circumferential direction of the support plate 22, and the wire rod 32 directed to the opposite circumferential direction is directed again to the shaft member 11. A third turning pulley 68 for turning in this way is provided on the support plate 22.

テンションアーム61は、その基端の軸部材11と平行な回動軸61aを支点として回動可能に支持板22に設けられる。この回動軸61aの回動角度は、その支持板22に取付けられた回動角度検出手段としてのポテンショメータ64により検出される。ポテンショメータ64の検出出力は制御手段であるコントローラ8(図1)に入力され、コントローラ8からの制御出力が、各公転体23における一対の小モータ41,41(図3)にそれぞれ接続される。   The tension arm 61 is provided on the support plate 22 so as to be rotatable about a rotation shaft 61a parallel to the shaft member 11 at the base end thereof. The rotation angle of the rotation shaft 61 a is detected by a potentiometer 64 as a rotation angle detection means attached to the support plate 22. The detection output of the potentiometer 64 is input to the controller 8 (FIG. 1) as control means, and the control output from the controller 8 is connected to a pair of small motors 41 and 41 (FIG. 3) in each revolution body 23, respectively.

また、テンションアーム61の回動軸61aと線材ガイド62との間の所定位置には、テンションアーム61の回動方向に付勢力を与える付勢手段としての弾性部材であるスプリング63の一端が取付けられる。テンションアーム61は、弾性部材63であるスプリング63によって回動角度に応じた弾性力が及ぼされる。このスプリング63の他端は、移動部材69に固定される。この移動部材69はテンション調節ネジ70に螺合しており、このネジ70の回転に従って移動調整が可能に構成される。このように、スプリング63の他端の固定位置は変位でき、テンションアーム61によって付与される線材32の張力が調節可能に構成される。   In addition, one end of a spring 63 that is an elastic member serving as a biasing unit that applies a biasing force in the rotation direction of the tension arm 61 is attached to a predetermined position between the rotation shaft 61 a of the tension arm 61 and the wire guide 62. It is done. The tension arm 61 is given an elastic force according to the rotation angle by a spring 63 which is an elastic member 63. The other end of the spring 63 is fixed to the moving member 69. The moving member 69 is screwed into the tension adjusting screw 70, and is configured to be movable and adjustable as the screw 70 rotates. Thus, the fixing position of the other end of the spring 63 can be displaced, and the tension of the wire 32 applied by the tension arm 61 can be adjusted.

制御手段であるコントローラ8(図1)は、回動角度検出手段であるポテンショメータ64により検出された回動角度が所定の角度となるように回転駆動手段であるモータ40(図3)を制御するように構成される。従って、この張力付与手段60では、スプリング63によりテンションアーム61を介して線材32に張力を与えて、そのテンションアーム61が所定の角度になるようにスプール31が回転して所定量の線材32が繰出される。よって、線材32の張力は所定の値に維持されるようになっている。   The controller 8 (FIG. 1) as the control means controls the motor 40 (FIG. 3) as the rotation driving means so that the rotation angle detected by the potentiometer 64 as the rotation angle detection means becomes a predetermined angle. Configured as follows. Therefore, in this tension applying means 60, tension is applied to the wire rod 32 via the tension arm 61 by the spring 63, and the spool 31 rotates so that the tension arm 61 becomes a predetermined angle, whereby a predetermined amount of the wire rod 32 is formed. It is paid out. Therefore, the tension of the wire 32 is maintained at a predetermined value.

図1の拡大図に示すように、軸部材11の先端側支持板22が設けられた部位には、第三転向プーリ68から軸部材11に向かう線材32を更に転向させてノズル11bを通過させ、その線材32を軸部材11の先端側から突出させる第四転向プーリ71がノズル11b毎に設けられる。従って、軸部材回転手段12によりこの軸部材11を回転させると、この軸部材11とともに芯線通路11aの周囲において複数のノズル11bが回転することになる。このため、軸部材11を回転させつつ、それら複数のノズル11bから線材32が繰り出されると、その繰り出された複数の線材32は撚られることになる。   As shown in the enlarged view of FIG. 1, the wire 32 directed from the third turning pulley 68 toward the shaft member 11 is further turned to pass through the nozzle 11 b at the portion of the shaft member 11 where the tip side support plate 22 is provided. A fourth turning pulley 71 for projecting the wire 32 from the tip end side of the shaft member 11 is provided for each nozzle 11b. Accordingly, when the shaft member 11 is rotated by the shaft member rotating means 12, the plurality of nozzles 11b are rotated around the core wire passage 11a together with the shaft member 11. For this reason, when the wire rod 32 is drawn out from the plurality of nozzles 11b while rotating the shaft member 11, the drawn-out wire rods 32 are twisted.

図1に示すように、この実施の形態では、軸部材11の中心軸に芯線13が通過する芯線通路11aを形成したので、その軸部材11の基端側から芯線通路11aに芯線13を供給する芯線供給機80を更に備え、その軸部材11の先端から繰り出された芯線13の周囲に複数のノズル11bから繰り出された線材32は螺旋状に巻き付けられ、芯線13の周囲に螺旋状に巻き付けられた複数の線材32から成る撚り線9が得られることになる。そして、そのように得られた撚り線9は回収手段90により回収される。   As shown in FIG. 1, in this embodiment, since the core wire passage 11a through which the core wire 13 passes is formed at the central axis of the shaft member 11, the core wire 13 is supplied from the proximal end side of the shaft member 11 to the core wire passage 11a. And a wire rod 32 fed out from the plurality of nozzles 11b is spirally wound around the core wire 13 and wound around the core wire 13 in a spiral manner. Thus, the stranded wire 9 composed of the plurality of wire rods 32 is obtained. The stranded wire 9 thus obtained is recovered by the recovery means 90.

この実施の形態における回収手段90は、撚り線9を等速でドラム91に巻き取るものであって、撚り線9を巻き取るためのドラム91と、そのドラム91を回転させる巻き取りモータ92と、ドラム91に巻き取られる撚り線9が掛け回される回収側速度検出プーリ93と、その回収側速度検出プーリ93の回転速度を検出する例えばエンコーダからなる回収側回転センサ94とを備える。   The collecting means 90 in this embodiment winds the stranded wire 9 around the drum 91 at a constant speed, and includes a drum 91 for winding the stranded wire 9 and a winding motor 92 for rotating the drum 91. A recovery-side speed detection pulley 93 around which the stranded wire 9 wound around the drum 91 is wound, and a recovery-side rotation sensor 94 made of, for example, an encoder that detects the rotational speed of the recovery-side speed detection pulley 93.

モータ92はその回転軸92aが軸部材11の中心軸C1に直交する面内になるように基板96に取付けられ、ドラム91はその回転軸92aに同軸に取付けられる。また、回収側速度検出プーリ93は、そこに掛け回される撚り線9が芯線通路11aの延長線上に位置するように、基板96に取付けられる。基板96には、この回収手段90を移動可能な複数のローラ97と、この回収手段90を設置可能な支持脚98とが設けられる。そして、撚り線9は回収側速度検出プーリ93に掛け回された後にドラム91に巻き取られるように構成される。ここで、図の符号99は、回収側速度検出プーリ93に掛け回された撚り線9が回収側速度検出プーリ93から外れないように、その回収側速度検出プーリ93と共に撚り線9を挟む挟持ローラ99を示す。   The motor 92 is attached to the substrate 96 such that the rotation shaft 92a is in a plane perpendicular to the central axis C1 of the shaft member 11, and the drum 91 is coaxially attached to the rotation shaft 92a. Further, the recovery side speed detection pulley 93 is attached to the substrate 96 so that the stranded wire 9 wound around the recovery side speed detection pulley 93 is positioned on the extension line of the core wire passage 11a. The substrate 96 is provided with a plurality of rollers 97 that can move the collection means 90 and support legs 98 on which the collection means 90 can be installed. The stranded wire 9 is configured to be wound around the drum 91 after being wound around the recovery-side speed detection pulley 93. Here, reference numeral 99 in the figure indicates that the stranded wire 9 wound around the recovery side speed detection pulley 93 is sandwiched between the recovery side speed detection pulley 93 and the stranded wire 9 so that the stranded wire 9 does not come off from the recovery side speed detection pulley 93. A roller 99 is shown.

回収側回転センサ94の検出出力は制御手段であるコントローラ8の制御入力に接続され、コントローラ8の制御出力は巻き取りモータ92に接続される。ここで、撚り線9のドラム91への巻き取り速度は、その撚り線9が掛け回された回収側速度検出プーリ93の回転速度により決まることになり、コントローラ8は、回収側回転センサ94が出力する回収側速度検出プーリ93の回転速度が一定になるように巻き取りモータ92を制御し、撚り線99を等速でドラム91に巻き取るように構成される。   The detection output of the collection side rotation sensor 94 is connected to the control input of the controller 8 which is a control means, and the control output of the controller 8 is connected to the winding motor 92. Here, the winding speed of the stranded wire 9 around the drum 91 is determined by the rotational speed of the recovery side speed detection pulley 93 around which the stranded wire 9 is wound. The winding motor 92 is controlled so that the rotation speed of the recovery-side speed detection pulley 93 to be output is constant, and the stranded wire 99 is wound around the drum 91 at a constant speed.

一方、芯線供給機80は、芯線13が巻回されて貯線された繰り出しスプール81と、その繰り出しスプール81を回転させる繰り出しモータ82と、繰り出しスプール81から巻解かれた芯線13が掛け回される供給側速度検出プーリ83と、その供給側速度検出プーリ83の回転速度を検出する例えばエンコーダからなる供給側回転センサ84とを備える。   On the other hand, the core wire feeder 80 is wound around a supply spool 81 around which the core wire 13 is wound and stored, a supply motor 82 for rotating the supply spool 81, and the core wire 13 unwound from the supply spool 81. A supply-side speed detection pulley 83 and a supply-side rotation sensor 84 configured to detect the rotation speed of the supply-side speed detection pulley 83, for example, an encoder.

モータ82はその回転軸82aが軸部材11の中心軸C1に直交する面内になるように基板86に取付けられ、繰り出しスプール81はその回転軸82aに同軸に取付けられる。また、供給側速度検出プーリ83は、そこに掛け回されて繰り出される芯線13が芯線通路11aに真っ直ぐに伸びてそのまま供給されるように、芯線通路11aの延長線上の基板86に取付けられる。基板86には、この芯線供給機80を移動可能な複数のローラ87と、この芯線供給機80を設置可能な支持脚88とが設けられる。そして、繰り出しスプール81が回転することにより巻解かれて繰り出された芯線13は、供給側速度検出プーリ83に掛け回された後、芯線通路11aに挿通される。   The motor 82 is attached to the substrate 86 so that the rotating shaft 82a is in a plane perpendicular to the central axis C1 of the shaft member 11, and the feeding spool 81 is coaxially attached to the rotating shaft 82a. Further, the supply side speed detection pulley 83 is attached to the substrate 86 on the extension line of the core wire passage 11a so that the core wire 13 wound around and fed out extends straight to the core wire passage 11a and is supplied as it is. The substrate 86 is provided with a plurality of rollers 87 that can move the core wire feeder 80 and support legs 88 on which the core wire feeder 80 can be installed. Then, the core wire 13 unwound and fed out by the rotation of the feed spool 81 is wound around the supply-side speed detection pulley 83 and then inserted into the core wire passage 11a.

供給側回転センサ84の検出出力は制御手段であるコントローラ8の制御入力に接続され、コントローラ8の制御出力は繰り出しモータ82に接続される。ここで、図の符号89は、供給側速度検出プーリ83に掛け回された芯線13が供給側速度検出プーリ83から外れないように、その供給側速度検出プーリ83と共に芯線13を挟む挟持ローラ89を示す。   The detection output of the supply side rotation sensor 84 is connected to the control input of the controller 8 which is a control means, and the control output of the controller 8 is connected to the feeding motor 82. Here, reference numeral 89 in the figure denotes a sandwiching roller 89 that sandwiches the core wire 13 together with the supply-side speed detection pulley 83 so that the core wire 13 wound around the supply-side speed detection pulley 83 does not come off from the supply-side speed detection pulley 83. Indicates.

芯線通路11aに挿通される芯線13の繰り出しは、繰り出しモータ82による繰り出しスプール81の回転により行われ、その繰り出し速度は、供給側速度検出プーリ83の回転速度により検出される。コントローラ8は、供給側回転センサ84が出力する供給側速度検出プーリ83の回転速度が一定になるように繰り出しモータ82を制御し、芯線13を等速で繰り出しスプール81から巻解いて、芯線通路11aに供給するように構成される。   The core wire 13 inserted through the core wire passage 11 a is fed by the rotation of the feeding spool 81 by the feeding motor 82, and the feeding speed is detected by the rotation speed of the supply side speed detection pulley 83. The controller 8 controls the feed motor 82 so that the rotation speed of the supply side speed detection pulley 83 output from the supply side rotation sensor 84 becomes constant, and unwinds the core wire 13 from the feed spool 81 at a constant speed, thereby 11a.

それとともに、コントローラ8は、回収側回転センサ94が出力する回収側速度検出プーリ93の回転速度から求められる撚り線9の回収速度と、供給側速度検出プーリ83の回転速度により決まる芯線13の繰り出し速度をそれぞれ求める。そして、制御手段であるコントローラ8は、芯線13の繰り出し速度と撚り線9の巻き取り速度が目標値となるように、巻き取りモータ92及び繰り出しモータ82をそれぞれ制御するように構成される。これにより、芯線13の繰り出し、撚り線9の巻き取りによってスプール31に巻回された芯線13の外径及びドラム91に巻き取られた撚り線9の外径が変化した場合でも、芯線13の繰り出し速度及び撚り線9の巻き取り速度を、目標値に保つように構成される。   At the same time, the controller 8 feeds the core wire 13 determined by the recovery speed of the stranded wire 9 obtained from the rotation speed of the recovery side speed detection pulley 93 output from the recovery side rotation sensor 94 and the rotation speed of the supply side speed detection pulley 83. Find each speed. And the controller 8 which is a control means is comprised so that the winding motor 92 and the feeding motor 82 may each be controlled so that the feeding speed of the core wire 13 and the winding speed of the stranded wire 9 may become target values. As a result, even when the outer diameter of the core wire 13 wound around the spool 31 and the outer diameter of the twisted wire 9 wound around the drum 91 change due to the feeding of the core wire 13 and the winding of the twisted wire 9, the core wire 13 The feeding speed and the winding speed of the stranded wire 9 are configured to be maintained at target values.

次に、本発明の撚り線の製造方法を説明する。   Next, the manufacturing method of the strand wire of this invention is demonstrated.

本発明の撚り線の製造方法は、複数のスプール31を軸部材11を中心として公転させ、それら複数のスプール31からそれぞれ巻き解かれて繰り出される複数の線材32が撚られた撚り線9を得る方法である。   The method for manufacturing a stranded wire according to the present invention obtains a stranded wire 9 in which a plurality of spools 31 are revolved around a shaft member 11 and a plurality of wire rods 32 are unwound from the plurality of spools 31 and fed out. Is the method.

その特徴ある点は、軸部材11の回転により軸部材11を中心として公転する複数の公転体23を設け、スプール31が回転して線材32を巻解くようにスプール31の中心軸C3を軸部材11の中心軸C1に直交する面内にしてスプール31を公転体23に枢支させ、スプール31を回転させる回転駆動手段40を公転体23に設け、複数の公転体23の自転を禁止しつつ軸部材11を中心として複数の公転体23を公転させ、スプール31から巻き解かれた線材32の張力が一定となるようにスプール31の回転を制御しつつ公転体23を公転させて複数の公転体23にそれぞれ設けられた複数のスプール31からそれぞれ巻き解かれて繰り出される複数の線材32を撚るところにある。   The characteristic point is that a plurality of revolution bodies 23 that revolve around the shaft member 11 by the rotation of the shaft member 11 are provided, and the central axis C3 of the spool 31 is unwound so that the spool 31 rotates and unwinds the wire 32. 11 in a plane perpendicular to the central axis C1 and pivotally supporting the spool 31 on the revolution body 23, and the revolution body 23 is provided with a rotation drive means 40 for rotating the spool 31, while prohibiting rotation of the plurality of revolution bodies 23. A plurality of revolution bodies 23 are revolved around the shaft member 11 and the revolution body 23 is revolved while controlling the rotation of the spool 31 so that the tension of the wire 32 unwound from the spool 31 is constant. The plurality of wire rods 32 are unwound from a plurality of spools 31 provided on the body 23 and fed out, respectively.

上記線材撚り装置10を用いる撚り線の製造方法にあっては、軸部材11の中心軸C1に芯線13が通過する芯線通路11aを形成したので、公転体23を公転させつつ軸部材11の基端側から芯線通路11aに芯線13を供給し、軸部材11の先端から繰り出された芯線13の周囲に線材32を螺旋状に巻き付けて撚り線9を製造することになる。   In the stranded wire manufacturing method using the wire twisting device 10, since the core wire passage 11 a through which the core wire 13 passes is formed on the central axis C <b> 1 of the shaft member 11, the base of the shaft member 11 is revolved while revolving the revolving member 23. The core wire 13 is supplied to the core wire passage 11a from the end side, and the wire rod 32 is spirally wound around the core wire 13 drawn from the tip of the shaft member 11, and the stranded wire 9 is manufactured.

その具体的な手順は以下のようになる。   The specific procedure is as follows.

即ち、先ず、芯線13が巻回されて貯線された繰り出しスプール81を準備し、その繰り出しスプール81を繰り出しモータ82の回転軸82aに取付け、繰り出しスプール81の回転軸を軸部材11の中心軸C1に直交する面内にする。そして、繰り出しスプール81から巻解いた芯線13を供給側速度検出プーリ83に掛け回した後、芯線通路11aに挿通する。   That is, first, a feeding spool 81 in which the core wire 13 is wound and stored is prepared, the feeding spool 81 is attached to the rotating shaft 82a of the feeding motor 82, and the rotating shaft of the feeding spool 81 is connected to the central axis of the shaft member 11. It is in a plane orthogonal to C1. Then, the core wire 13 unwound from the supply spool 81 is wound around the supply-side speed detection pulley 83 and then inserted into the core wire passage 11a.

一方、線材32が巻回されて貯線された複数のスプール31を準備し、それらを複数の公転体23に枢支させる。具体的には、同軸になるように設けられて互いに離間した一対の係止棒36の間にスプール31を位置させ、その後に一対の係止棒36を互いに近づけてスプール31をその中心軸C3の両側から挟む。それにより、そのスプール31の中心軸C3を軸部材11の中心軸C1に直交する面内にして、そのスプール31を公転体23に枢支する。そして、スプール31を支持した係止棒36を係止具37に係止させて互いに離間することを防止する。   On the other hand, a plurality of spools 31 in which the wire 32 is wound and stored are prepared, and are pivotally supported by the plurality of revolution bodies 23. Specifically, the spool 31 is positioned between a pair of locking rods 36 provided so as to be coaxial and spaced apart from each other, and then the pair of locking rods 36 are brought close to each other to move the spool 31 to its central axis C3. Sandwich from both sides. Thus, the spool 31 is pivotally supported on the revolution body 23 with the center axis C3 of the spool 31 being set in a plane orthogonal to the center axis C1 of the shaft member 11. Then, the locking rod 36 that supports the spool 31 is locked by the locking tool 37 and is prevented from being separated from each other.

その後、図2に示すように、スプール31から線材32を巻解いて一対のローラ51,51間に挟み、一対のローラ51,51により案内された線材32を複数のプーリ52,52に掛回して軸部材11の先端側支持板22に枢支された枢支部材23dに貫通させる。そして、枢支部材23dを貫通した線材32を張力付与手段60を介してノズル11bに貫通させる。   Thereafter, as shown in FIG. 2, the wire 32 is unwound from the spool 31 and sandwiched between the pair of rollers 51, 51, and the wire 32 guided by the pair of rollers 51, 51 is wound around a plurality of pulleys 52, 52. Then, the shaft member 11 is passed through the pivot member 23d pivotally supported by the tip side support plate 22 of the shaft member 11. Then, the wire 32 penetrating the pivot member 23d is passed through the nozzle 11b via the tension applying means 60.

具体的には、枢支部材23dに貫通させた線材32を、第一及び第二転向プーリ66,67、線材ガイド62、第三及び第四転向プーリ68,71に順次掛け回し、その後に軸部材11の先端に形成されたノズル11bに貫通させる。このように複数のノズル11bからそれぞれ順次引き出された複数の線材32を、軸部材11の先端から引き出された芯線13と共に回収手段90である回収側速度検出プーリ93に掛け回し、その後ドラム91にそれらの端部を係止させる。   Specifically, the wire 32 passed through the pivot member 23d is sequentially wound around the first and second turning pulleys 66 and 67, the wire guide 62, the third and fourth turning pulleys 68 and 71, and then the shaft. The nozzle 11b formed at the tip of the member 11 is penetrated. In this way, the plurality of wire rods 32 sequentially drawn from the plurality of nozzles 11 b are hung around the collection side speed detection pulley 93 as the collection means 90 together with the core wire 13 drawn from the tip of the shaft member 11, and then to the drum 91. Lock their ends.

この状態から、ドラム91が巻き取る回収速度と、芯線供給機80における芯線13の繰り出し速度が目標値となるように、巻き取りモータ92及び繰り出しモータ82をそれぞれ制御する。   From this state, the take-up motor 92 and the take-out motor 82 are controlled so that the recovery speed at which the drum 91 winds up and the feed speed of the core wire 13 in the core wire feeder 80 become the target values.

巻き取りモータ92がドラム91を回転させて芯線13とともにノズル11bから繰り出される複数の線材32を巻き取って回収すると、その線材32が掛け回されて折り返された線材ガイド62は第二及び第三プーリ67,68に近づくので、張力付与手段60におけるテンションアーム61は揺動し、その回転は回動角度検出手段としてのポテンショメータ64により検出される。   When the winding motor 92 rotates the drum 91 to wind up and collect the plurality of wire rods 32 fed from the nozzle 11b together with the core wire 13, the wire rod guides 62 that are wound around and turned up are the second and third wire rod guides 62. As the pulleys 67 and 68 are approached, the tension arm 61 in the tension applying means 60 swings, and its rotation is detected by a potentiometer 64 as a rotation angle detecting means.

このポテンショメータ64の検出出力は制御手段であるコントローラ8(図1)に入力され、コントローラ8(図1)は、回動角度検出手段であるポテンショメータ64により検出された回動角度が、所定の角度となるように回転駆動手段であるモータ40(図3)を制御し、各公転体23におけるスプール31を回転させ、所定の張力が付与された状態で線材32を順次繰り出す。   The detection output of the potentiometer 64 is input to the controller 8 (FIG. 1) as control means, and the controller 8 (FIG. 1) detects that the rotation angle detected by the potentiometer 64 as rotation angle detection means is a predetermined angle. The motor 40 (FIG. 3) which is a rotation driving means is controlled so that the spool 31 in each revolution body 23 is rotated, and the wire 32 is sequentially fed out with a predetermined tension applied.

このように、張力が一定となるようにスプール31の回転が制御された状態で、軸部材11を回転させて複数のスプール31を軸部材11を中心として公転させ、複数のスプール31からそれぞれ巻き解かれて軸部材11の先端における複数のノズル11bから順次繰り出される複数の線材32を、軸部材11の先端から順次繰り出される芯線13の周囲に螺旋状に巻き付けて撚り線9を製造する。そして、製造された撚り線9を順次ドラム91に巻き付けて回収する。   In this way, in a state where the rotation of the spool 31 is controlled so that the tension is constant, the shaft member 11 is rotated to revolve the plurality of spools 31 around the shaft member 11, and each of the spools 31 is wound around. The stranded wire 9 is manufactured by winding a plurality of wire rods 32 that are unwound and sequentially fed out from the plurality of nozzles 11b at the tip of the shaft member 11 around the core wire 13 that is drawn out from the tip of the shaft member 11 in a spiral manner. And the manufactured strand 9 is wound around the drum 91 sequentially, and is collect | recovered.

制御手段であるコントローラ8は、芯線13の繰り出し速度、撚り線9の巻き取り速度が目標値となるように、巻き取りモータ92及び繰り出しモータ82をそれぞれ制御するとともに、軸部材11の回転速度を均一にして、芯線13の周囲に螺旋状に巻回される線材32の巻き付けピッチを均一にする。   The controller 8 that is a control means controls the winding motor 92 and the feeding motor 82 so that the feeding speed of the core wire 13 and the winding speed of the stranded wire 9 become target values, and the rotational speed of the shaft member 11 is controlled. The winding pitch of the wire 32 wound spirally around the core wire 13 is made uniform.

この時、軸部材11の周囲において公転する複数の公転体23の自転を禁止する。公転体23の自転の禁止は、自転禁止手段25により行われる。そして、張力付与手段60により付与された線材32の張力は、制御手段であるコントローラ8が、張力付与手段60におけるテンションアーム61が所定の角度になるようにスプール31を回転させ、このように回転駆動手段であるモータ40を制御することにより、所定の値に維持することになる。   At this time, the rotation of the plurality of revolution bodies 23 that revolve around the shaft member 11 is prohibited. The rotation of the revolution body 23 is prohibited by the rotation prohibiting means 25. And the tension | tensile_strength of the wire 32 provided by the tension | tensile_strength provision means 60 rotates the spool 31 so that the controller 8 which is a control means may rotate the tension arm 61 in the tension | tensile_strength provision means 60 to a predetermined angle, and rotates in this way. By controlling the motor 40 which is a driving means, the predetermined value is maintained.

このような線材撚り装置10及び撚り線の製造方法では、線材32を繰り出すスプール31の中心軸C3を軸部材11の中心軸C1に直交する面内にしてスプール31を公転体23に枢支したので、回転駆動手段40によりスプール31を回転させて線材32を巻解くことにより、その線材32を軸部材11の長手方向に引き出すことができる。すると、線材32はスプール31の円周方向に引き出され、その引き出しの際に線材32が捩られるようなことはない。   In such a wire twisting device 10 and a method of manufacturing a twisted wire, the spool 31 is pivotally supported on the revolution body 23 with the central axis C3 of the spool 31 that feeds the wire 32 in a plane orthogonal to the central axis C1 of the shaft member 11. Therefore, the wire 32 can be pulled out in the longitudinal direction of the shaft member 11 by rotating the spool 31 by the rotation driving means 40 and unwinding the wire 32. Then, the wire 32 is pulled out in the circumferential direction of the spool 31, and the wire 32 is not twisted when being pulled out.

よって、本発明では、複数のスプール31から線材32を所望の速度で捩ることなく引き出して撚ることのできるものとなる。これにより、得られた撚り線9の所望の撚り状態は維持され、得られた撚り線9の撚りの程度が局部的に異なるようなことはなく、撚りの程度が均一な撚り線9を得ることが可能となる。   Therefore, in the present invention, the wire 32 can be pulled out from the plurality of spools 31 without twisting at a desired speed and twisted. Thereby, the desired twisted state of the obtained stranded wire 9 is maintained, the degree of twisting of the obtained stranded wire 9 is not locally different, and the stranded wire 9 having a uniform degree of twisting is obtained. It becomes possible.

そして、回転駆動手段がスプール31に並列に設けられたモータ40であれば、そのモータ40をスプール31の軸方向に設ける場合に比較して、公転体23の幅方向の寸法を小さくすることができ、公転体23の幅方向の寸法が拡大することに起因する公転半径の拡大は回避される。   If the rotational drive means is a motor 40 provided in parallel with the spool 31, the dimension of the revolution body 23 in the width direction can be made smaller than when the motor 40 is provided in the axial direction of the spool 31. The expansion of the revolution radius resulting from the expansion of the dimension of the revolution body 23 in the width direction is avoided.

また、そのモータ40は、回転軸41aが同軸に連結された一対の小モータ41,41から成る様であれば、同一の動力を出力するにもかかわらず、単一のモータによりスプール31を回転させる場合に比較して、モータ41,41の径方向の寸法を小さくすることができ、そのモータ41,41が設けられる公転体23の回転軸C2方向における寸法を小さくすることもできる。これらにより、公転半径が拡大することや、公転体23の回転軸C2方向における寸法が拡大することに起因する装置10の大型化を回避することができる。   Further, if the motor 40 is composed of a pair of small motors 41 and 41 having a rotating shaft 41a coaxially connected, the spool 31 is rotated by a single motor, although the same power is output. Compared with the case where it makes it, the dimension of the radial direction of the motors 41 and 41 can be made small, and the dimension in the rotating shaft C2 direction of the revolution body 23 in which the motors 41 and 41 are provided can also be made small. By these, the enlargement of the revolution radius and the enlargement of the apparatus 10 resulting from the dimension in the rotating shaft C2 direction of the revolution body 23 can be avoided.

そして、複数のスプール31から別々に巻解かれた複数の線材32に別々に所定の張力を加える複数の張力付与手段60を設けているので、各ノズル11bから繰出される線材32のそれぞれの張力を略等しくすることができ、ノズル11bから繰出される線材32相互の張力変動が押さえられる。これにより、その張力変動を押さえて、所定のピッチで規則正しく撚られた複数の線材32から成る撚り線9を得ることができる。   And since the several tension | tensile_strength provision means 60 which applies predetermined | prescribed tension | tensile_strength separately to the several wire 32 unwound separately from the several spool 31 is provided, each tension | tensile_strength of the wire 32 drawn | fed out from each nozzle 11b Can be made substantially equal, and the tension variation between the wires 32 fed from the nozzle 11b is suppressed. Thereby, the tension | tensile_strength fluctuation | variation can be suppressed and the strand wire 9 which consists of the some wire rod 32 regularly twisted by the predetermined pitch can be obtained.

一方、スプール31に貯線された線材32の巻回された直径は、線材32が引き出される従って小さくなり、スプール31の回転速度が一定であれば、その周方向に引き出される線材32の速度は変動することになる。けれども、引き出される線材32の速度変動は、線材32の張力に影響を与えるので、張力付与手段60によりその線材32に付与される張力が一定となるようにスプール31の回転を制御すれば、スプール31に巻回された線材32の外径が変化した場合でも、そのスプール31から引き出される線材32の速度を目標値に保つことができ、その速度が変動するような事態を回避することができる。   On the other hand, the wound diameter of the wire 32 stored in the spool 31 decreases as the wire 32 is pulled out. If the rotation speed of the spool 31 is constant, the speed of the wire 32 drawn in the circumferential direction is Will fluctuate. However, since the speed fluctuation of the drawn wire 32 affects the tension of the wire 32, if the rotation of the spool 31 is controlled so that the tension applied to the wire 32 by the tension applying means 60 becomes constant, the spool Even when the outer diameter of the wire 32 wound around 31 changes, the speed of the wire 32 drawn out from the spool 31 can be maintained at the target value, and a situation in which the speed fluctuates can be avoided. .

よって、スプール31の回転速度が繰り出される線材32の速度変動に追従できないような事態は回避され、線材32を所望の速度で引き出すことができない場合に生じる線材32が引き千切られるような事態を回避することもできる。   Therefore, a situation in which the rotation speed of the spool 31 cannot follow the speed fluctuation of the wire rod 32 is avoided, and a situation in which the wire rod 32 generated when the wire rod 32 cannot be pulled out at a desired speed is avoided. You can also

なお、上述した実施の形態では、軸部材回転手段12として、サーボモータ12aを備えたものを例示したけれども、この軸部材回転手段12は、複数のノズル11bが先端に形成された軸部材11を回転可能である限り、モータに限られない。例えば、圧縮エア等の流体圧により軸部材11を回転可能な流体圧モータを備えるようなものであっても良い。   In the above-described embodiment, the shaft member rotating means 12 is illustrated as having the servo motor 12a. However, the shaft member rotating means 12 includes the shaft member 11 having a plurality of nozzles 11b formed at the tip. As long as it can rotate, it is not limited to a motor. For example, it may include a fluid pressure motor that can rotate the shaft member 11 by fluid pressure such as compressed air.

また、上述した実施の形態では、スプロケット26,27とチェーン28を用いた自転禁止手段25を例示したけれども、この自転禁止手段は25は、公転体23の自転を禁止しうる限り、これに限られるものではなく、例えば、ベルトとプーリを用いたようなものであっても良く、ギヤを用いたようなものであっても良い。   In the above-described embodiment, the rotation prohibiting means 25 using the sprockets 26 and 27 and the chain 28 is illustrated. However, the rotation prohibiting means 25 is limited to this as long as the rotation of the revolution body 23 can be prohibited. For example, a belt and a pulley may be used, or a gear may be used.

また、上述した実施の形態では、6本の線材32が芯線13の周囲に螺旋状に巻き付けられた撚り線を得る場合を説明した。けれども、撚られる線材32の数は6本に限られない。この場合、撚るべき線材32の数に等しいか又はそれ以上の数のノズル11bを軸部材11の先端に設け、軸部材回転手段12が軸部材11を回転させる。このように、それら複数のノズル11bを同時に回転可能である限り、線材32の数は、3本であっても、4本であっても、5本であっても、7本以上であっても良い。   Further, in the above-described embodiment, the case has been described in which six wires 32 obtain a stranded wire wound around the core wire 13 in a spiral shape. However, the number of wires 32 twisted is not limited to six. In this case, the number of nozzles 11b equal to or greater than the number of wires 32 to be twisted is provided at the tip of the shaft member 11, and the shaft member rotating means 12 rotates the shaft member 11. Thus, as long as the plurality of nozzles 11b can be rotated at the same time, the number of the wires 32 is three, four, five, seven, or more. Also good.

また、上述した実施の形態では、得られた撚り線9を回収手段90であるドラム91に巻き付けて貯線する場合を説明した。けれども、得られた撚り線9は必ずしも貯線しなくても良い。例えば、得られた撚り線9を図示しない巻線機にそのまま供給して、その巻線機により直ちに巻線に使用するようにしても良い。   Further, in the above-described embodiment, the case where the obtained stranded wire 9 is wound around the drum 91 which is the collecting means 90 and stored is described. However, the obtained stranded wire 9 does not necessarily have to be stored. For example, the obtained stranded wire 9 may be supplied to a winding machine (not shown) as it is and used for winding immediately by the winding machine.
