 図面を参照して、本発明の実施形態に係る線材撚り装置について説明する。 A wire strand twisting device according to an embodiment of the present invention will be described with reference to the drawings.
 線材撚り装置10は、図1に示すように、軸部材11と、軸部材11の中心軸を回転中心として軸部材11を回転させる軸部材回転機構12と、を備える。軸部材11は断面が円形の棒状部材であって、軸部材11の中心軸には芯線13が通過する芯線通路11aが形成される。軸部材11の先端には、後述するスプール31から巻解かれて繰り出される線材32が挿通される複数のノズル11bが、芯線通路11aを中心に放射状に等角度に設けられる(図5)。 As shown in FIG. 1, the wire strand twisting device 10 includes a shaft member 11 and a shaft member rotation mechanism 12 that rotates the shaft member 11 about the central axis of the shaft member 11 as a rotation center. The shaft member 11 is a rod-like 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. At the tip end of the shaft member 11, a plurality of nozzles 11b through which a wire 32 unwound and fed from a spool 31 to be described later is inserted are provided radially at equal angles around the core passage 11a (FIG. 5).
 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、例えば、図5に示すように、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。 The nozzle 11b is a hole formed parallel to the core line passage 11a at the tip of the shaft member 11. For example, as shown in FIG. 5, the nozzle 11b consisting of a hole is formed every 60 degrees around the core line passage 11a. Six pieces are formed.
 軸部材11は、基端側端縁と先端側端縁とがベアリング14a,15aを介してそれぞれ台板14,15に回転自在に支持される。台板14,15は、軸部材11が水平になるように基台16に立設される。基台16には、基台16を移動可能な複数のローラ16aと、基台16を設置可能な複数の支持脚16bと、が設けられる。 As for the shaft member 11, the base end side edge and the front end side edge are rotatably supported by the base plates 14 and 15 via the bearings 14a and 15a, respectively. The base plates 14 and 15 are erected on the base 16 so that the shaft member 11 is horizontal. The base 16 is provided with a plurality of rollers 16 a capable of moving the base 16 and a plurality of support legs 16 b on which the base 16 can be installed.
 基端側台板14には、軸部材回転機構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る。サーボモータ12aの回転軸12bには第一プーリ12cが取り付けられる。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との間にはベルト12eが掛け回される。サーボモータ12aには、制御装置であるコントローラ8の制御出力が接続される。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を介して第二プーリ12dに伝達され、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。 The servomotor 12a which comprises the shaft member rotation mechanism 12 is provided in the base end side base plate 14 so that the rotating shaft 12b may become parallel to the shaft member 11. As shown in FIG. The first pulley 12c is attached to the rotation shaft 12b of the servomotor 12a. A second pulley 12d is provided on the proximal end side of the shaft member 11 corresponding to the first pulley 12c, and a belt 12e is wound around the first pulley 12c and the second pulley 12d. The control output of a controller 8 which is a control device is connected to the servomotor 12a. When the servomotor 12a is driven by the command from the controller 8 and the rotary shaft 12b rotates with the first pulley 12c, the rotation is transmitted to the second pulley 12d via the belt 12e, and the shaft provided with the second pulley 12d The member 11 rotates around the core passage 11a.
 軸部材11には、中心軸方向に所定の間隔を開けて一対の支持板21,22が設けられる。一対の支持板21,22には複数の公転体23が回転自在に支持される(図1には二台の公転体23が示される)。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と平行になるように一対の支持板21,22に回転自在に支持される。公転体23の数は、ノズル11bと同数であり、この場合は6個設けられる(図4及び図5)。 The shaft member 11 is provided with a pair of support plates 21 and 22 at predetermined intervals in the central axis direction. A plurality of revolving bodies 23 are rotatably supported by the pair of support plates 21 and 22 (two revolving bodies 23 are shown in FIG. 1). The plurality of revolution bodies 23 are rotatably supported by the pair of support plates 21 and 22 such that their rotation axes C2 are parallel to the central axis C1 of the shaft member 11. The number of revolving bodies 23 is the same as that of the nozzles 11 b, and in this case, six 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つについて説明する。図3に示すように、公転体23は、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、を有し、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る。枢支部材23c,23dは一対の支持板21,22にベアリング21a,22aを介してそれぞれ回転自在に支持される。このように、複数の公転体23は、回転軸C2が軸部材11と平行になるように支持板21,22に回転自在に支持され、軸部材11の回転により軸部材11を中心として公転する。 Since the plurality of revolving bodies 23 have the same structure, one of them will be described. As shown in FIG. 3, the revolving body 23 has a square portion 23 a located on the base end side of the shaft member 11 and a trapezoidal portion 23 b located on the tip end side of the shaft member 11 in plan view. Cylindrical pivot members 23c and 23d are respectively provided at both ends of the rotary shaft C2 of the second embodiment. The pivot members 23c and 23d are rotatably supported by the pair of support plates 21 and 22 via bearings 21a and 22a. As described above, the plurality of revolution bodies 23 are rotatably supported by the support plates 21 and 22 such that the rotation axis C2 is parallel to the shaft member 11, and revolves around the shaft member 11 by the rotation of the shaft member 11. .
 また、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機構25が設けられる。図4に示すように、自転禁止機構25は、公転体23の基端側の枢支部材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と同じ大きさであり同じ形状であって軸部材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、第一及び第二スプロケット27を連結するチェーン28と、を有する。なお、符号27aで示される部材は、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。 In addition, the wire twisting device 10 is provided with a rotation prohibition mechanism 25 that prohibits rotation of the revolving body 23. As shown in FIG. 4, the rotation inhibiting mechanism 25 includes a first sprocket 26 provided coaxially with the rotation axis C2 of the revolving member 23 on the pivoting member 23 c on the base end side of the revolving member 23, and the first sprocket 26 The second sprocket 27 and the first and second sprockets 27 which are non-rotatably attached to the base plate 14 (FIG. 1) so as to have the same size and the same shape and be coaxial with the shaft member 11 And a chain 28 to be connected. The member indicated by reference numeral 27a is a mounting leg 27a for attaching the second sprocket 27 to the base plate 14 (FIG. 1).
 このように、軸部材11が回転しても、第二スプロケット27は回転しない。従って、第二スプロケット27にチェーン28を介して連結された第二スプロケット27と同じ大きさであり同じ形状である第一スプロケット26は、軸部材11を中心として公転しても、第一スプロケット26自体が回転することはないため、第一スプロケット26が枢支部材23cに設けられた公転体23は、自転することが禁止される。 Thus, even if the shaft member 11 rotates, the second sprocket 27 does not rotate. Therefore, even if the first sprocket 26 which is the same size and shape as the second sprocket 27 connected to the second sprocket 27 via the chain 28 is the first sprocket 26 even if it revolves around the shaft member 11. Since the motor itself does not rotate, the revolving body 23 provided with the first sprocket 26 on the pivoting member 23c is prohibited from rotating.
 よって、図1及び図4に示すように、公転体23が基台16と平行な水平状態(基準状態)で一対の支持板21,22間に架設されている場合、支持板21,22が軸部材11とともに回転すると、複数の公転体23は、軸部材11の周囲を公転するものの、公転体23は自転することが禁止されるため、複数の公転体23は、水平状態(基準状態)を維持したままで軸部材11の周囲を公転することになる。 Therefore, as shown in FIGS. 1 and 4, when the revolving body 23 is bridged between the pair of support plates 21 and 22 in a horizontal state (reference state) parallel to the base 16, the support plates 21 and 22 are When rotating with the shaft member 11, the plurality of orbiting bodies 23 revolve around the shaft member 11, but the revolving body 23 is prohibited from rotating, so the plurality of revolution bodies 23 are in the horizontal state (reference state) While rotating the shaft member 11 around.
 図4に示すように、支持板21には、6個の公転体23が60度毎に設けられており、周方向に隣接する一対の公転体23におけるそれぞれの第一スプロケット26には、単一のチェーン28が掛け回され、そのチェーン28は軸部材11と同軸に設けられた単一の第二スプロケット27に更に掛け回される。このように、6個の公転体23は3本のチェーン28によってそれぞれが自転することが禁止される。また、各チェーン28の弛みを取るように、チェーン28にテンションを付与する補助スプロケット29がそれぞれ設けられる。 As shown in FIG. 4, six revolving bodies 23 are provided on the supporting plate 21 every 60 degrees, and each first sprocket 26 in a pair of revolving bodies 23 adjacent in the circumferential direction is a single One chain 28 is wound around, and the chain 28 is further wound around a single second sprocket 27 provided coaxially with the shaft member 11. Thus, the six revolving bodies 23 are prohibited from rotating by the three chains 28 respectively. Further, auxiliary sprockets 29 are provided to apply tension to the chains 28 so as to remove slack of the chains 28.
 また、軸部材11の基端を回転自在に支持する台板14には、図1に示すように、自転禁止機構25や軸部材回転機構12を構成するプーリ12c,12d及びベルト12e等を覆う覆い部材30が設けられる。 Further, as shown in FIG. 1, the base plate 14 rotatably supporting the base end of the shaft member 11 covers the pulleys 12c and 12d, the belt 12e and the like constituting the rotation inhibition mechanism 25 and the shaft member rotation mechanism 12. A covering member 30 is provided.
 図3に示すように、複数の公転体23における方形部23aには、線材32が巻回されたスプール31がそれぞれ取付けられる。スプール31の取付け構造は、それぞれ同一であるので、その内の1つについて説明する。スプール31は、スプール31が回転することで線材32が巻解かれるように、スプール31の中心軸C3が軸部材11の中心軸C1及びそれに平行な公転体23の回転軸C2に対して直交するように公転体23に回転自在に支持される。 As shown in FIG. 3, the spools 31 around which the wire 32 is wound are attached to the rectangular portions 23 a of the plurality of revolution bodies 23 respectively. The attachment structures of the spools 31 are identical to each other, so one of them will be described. In the spool 31, the central axis C3 of the spool 31 is orthogonal to the central axis C1 of the shaft member 11 and the rotation axis C2 of the revolving member 23 parallel thereto so that the wire 32 is unwound by rotation of the spool 31. It is rotatably supported by the revolving body 23 as shown in FIG.
 このようにスプール31を支持するために、公転体23の方形部23aには、スプール31の両側を支持する一対の支持部材33,33が設けられる。支持部材33は、方形部23aに固定される円筒状の取付材34と、ベアリングを介して取付材34の内周面に支持される円筒状の回転体35と、回転体35にスプライン結合されて軸方向に移動可能に設けられた係止棒36と、を有する。軸部材11の中心軸C1に対して係止棒36の中心軸が直交するように取付材34は公転体23の方形部23aに取り付けられる。一対の支持部材33,33の係止棒36,36は、互いにスプール31に対して離接可能に取付けられる。 As described above, in order to support the spool 31, the rectangular portion 23 a of the revolving body 23 is provided with a pair of support members 33 and 33 that support both sides of the spool 31. The support member 33 is splined to the cylindrical mounting member 34 fixed to the rectangular portion 23a, the cylindrical rotary body 35 supported on the inner circumferential surface of the mounting member 34 via a bearing, and the rotary body 35. And an axially movable locking rod 36. The mounting member 34 is attached to the rectangular portion 23 a of the revolving body 23 so that the central axis of the locking rod 36 is orthogonal to the central axis C 1 of the shaft member 11. The locking bars 36, 36 of the pair of support members 33, 33 are attached to the spool 31 so as to be able to be separated from each other.

And the connector 47 for electrically connecting the motor 40 and the like provided on the revolving body 23 are shown.
 図2及び図3に示すように、公転体23の方形部23aと台形部23bとの境には、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)における中央に案内する一対のローラ51,51が設けられる。また、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が枢支部材23d内を挿通するように案内する複数のプーリ52,52が設けられる。 As shown in FIG. 2 and FIG. 3, at the boundary between the rectangular portion 23 a and the trapezoidal portion 23 b of the revolving member 23, the wire member 32 unwound from the spool 31 provided in the rectangular portion 23 a A pair of rollers 51, 51 guiding to the center in the width direction (the direction of the central axis C3 of the spool 31) is provided. Further, the trapezoidal portion 23b is provided with a plurality of pulleys 52, 52 for guiding the wire 32 guided by the pair of rollers 51, 51 to be inserted through the pivot support member 23d.
 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、図2に示すように、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る。このため、スプール31に巻回された線材32を公転体23の表面側と裏面側とのいずれの側に巻解いても、巻解かれた線材32を枢支部材23dに導くことが可能である。 As shown in FIG. 2, the pair of rollers 51, 51 and the pulleys 52, 52 are attached to both the front and back sides (upper and lower sides in FIG. 2) of the revolving member 23, as shown in FIG. Be Therefore, even if the wire 32 wound around the spool 31 is unwound on either side of the surface side and the back side of the revolving member 23, the unwound wire 32 can be guided to the pivoting member 23d. is there.
 スプール31から巻解かれて枢支部材23d内を貫通した線材32は、ノズル11b(図1)へと案内される。図5に示すように、先端側支持板22には、スプール31から供給されノズル11bへと案内される線材32に張力を付与する張力付与機構60が設けられる。 The wire 32 unwound from the spool 31 and passing through the pivot member 23d is guided to the nozzle 11b (FIG. 1). As shown in FIG. 5, the tip end side support plate 22 is provided with a tension applying mechanism 60 for applying tension to the wire 32 supplied from the spool 31 and guided to the nozzle 11b.
 張力付与機構60は、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、テンションアーム61の先端に取り付けられ線材32が掛け回される線材ガイド62と、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に回動角度に応じた弾性力を付与する弾性部材63と、テンションアーム61の回動角度を検出する回動角度検出器64と、を有する。 The tension applying mechanism 60 includes a tension arm 61 provided on the tip side support plate 22 and rotatable around a pivot, a wire guide 62 attached to the tip of the tension arm 61 and around which the wire 32 is wound, and tension An elastic member 63 for applying an elastic force according to the rotation angle to the tension arm 61 at a predetermined position between the rotation support point of the arm 61 and the wire rod guide 62, and a rotation angle for detecting the rotation angle of the tension arm 61 And a detector 64.
 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に向けて転向させる第一転向プーリ66と、軸部材11に向かう線材32を先端側支持板22の周方向に向かわせることで線材ガイド62に向けて転向させる第二転向プーリ67とが、設けられる。 That is, the wire 32 unwound from the spool 31 and penetrating the pivot member 23 d is guided to the wire guide 62 at the tip of the tension arm 61. For this reason, in the front end side support plate 22, the first diverting pulley 66 which turns the wire 32 penetrating the pivoting member 23 d toward the shaft member 11, and the wire 32 facing the shaft member 11 in the front end side support plate 22. A second diverting pulley 67 is provided which is diverted towards the wire guide 62 by directing it circumferentially.
 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、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は線材ガイド62に掛け回されて折り返される。支持板22には、線材ガイド62で折り返された線材32を再び軸部材11に向けて転向させる第三転向プーリ68が設けられる。 The tension arm 61 provided with the wire guide 62 at the tip extends in the diameter direction of the support plate 22 so that the wire 32 deflected in the circumferential direction of the tip side support plate 22 by the second deflection pulley 67 reaches the wire guide 62 Provided. The wire 32 guided to the wire guide 62 is wound around the wire guide 62 and folded back. The support plate 22 is provided with a third diverting pulley 68 for diverting the wire 32 folded back by the wire guide 62 toward the shaft member 11 again.
 テンションアーム61は、軸部材11と平行に支持板22に設けられる回動軸61aを支点として回動可能である。回動軸61aの回動角度は、支持板22に取付けられた回動角度検出器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の検出出力は制御装置であるコントローラ8(図1)に入力される。また、コントローラ8は、各公転体23における一対の小型モータ41,41(図3)に接続される。 The tension arm 61 is rotatable in parallel with the shaft member 11 with a pivot shaft 61 a provided on the support plate 22 as a fulcrum. The rotation angle of the rotation shaft 61 a is detected by a potentiometer 64 as a rotation angle detector attached to the support plate 22. The detection output of the potentiometer 64 is input to a controller 8 (FIG. 1) which is a control device. Moreover, the controller 8 is connected to a pair of small motors 41 and 41 (FIG. 3) in each revolving body 23.
 また、回動軸61aと線材ガイド62との間のテンションアーム61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には、スプリング63によって回動角度に応じた弾性力が付与される。スプリング63の他端は、移動部材69に固定される。移動部材69はテンション調節ネジ70に螺合されており、ネジ70を回転させることによって移動量を調整することが可能である。このように、スプリング63の他端の固定位置は変位可能であり、テンションアーム61によって線材32に付与される張力を調節することが可能である。 Further, at a predetermined position of the tension arm 61 between the pivot shaft 61a and the wire guide 62, one end of a spring 63, which is an elastic member as an urging means for applying an urging force in the pivoting direction of the tension arm 61, is attached. Be The spring 63 applies an elastic force to the tension arm 61 according to the rotation angle. 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 the amount of movement can be adjusted by rotating the screw 70. In this manner, the fixed position of the other end of the spring 63 is displaceable, and the tension applied to the wire 32 by the tension arm 61 can be adjusted.
 制御装置であるコントローラ8(図1)は、回動角度検出器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機構であるモータ40(図3)を制御する。このように、張力付与機構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に張力が付与され、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を回転させる。この結果、所定量の線材32が繰出されるとともに、線材32の張力は所定の値に維持される。 The controller 8 (FIG. 1), which is a control device, controls the motor 40 (FIG. 3), which is a rotational drive mechanism, such that the rotation angle detected by the potentiometer 64, which is a rotation angle detector, becomes a predetermined angle. . Thus, in the tension applying mechanism 60, tension is applied to the wire 32 by the spring 63 via the tension arm 61, and the spool 31 is rotated so that the tension arm 61 is at a predetermined angle. As a result, the wire 32 of a predetermined amount is fed out, and the tension of the wire 32 is maintained at a predetermined value.
 図1の拡大図に示すように、先端側支持板22が設けられる軸部材11の部位には、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を通過させる第四転向プーリ71がノズル11b毎に設けられる。ノズル11bを通過した線材32は、軸部材11の先端側から繰り出される。従って、軸部材回転機構12により軸部材11を回転させると、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、複数のノズル11bから線材32が繰り出されると、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, in the portion of the shaft member 11 where the distal end side support plate 22 is provided, the wire 32 directed from the third turning pulley 68 toward the shaft member 11 is further turned to pass the nozzle 11 b. Four diverting pulleys 71 are provided for each nozzle 11b. The wire 32 passing through the nozzle 11 b is drawn out from the tip end side of the shaft member 11. Therefore, when the shaft member 11 is rotated by the shaft member rotating mechanism 12, the plurality of nozzles 11 b rotate around the core passage 11 a together with the shaft member 11. For this reason, when the wire 32 is drawn from the plurality of nozzles 11 b while the shaft member 11 is rotated, the drawn plurality of wires 32 are twisted.
 図1に示すように、軸部材11の中心軸には、芯線13が通過する芯線通路11aが形成されている。このため、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が更に設けられる。芯線供給機80から供給され、軸部材11の先端から繰り出された芯線13の周囲には、複数のノズル11bから繰り出された線材32が螺旋状に巻き付けられる。このように、芯線13の周囲に複数の線材32が螺旋状に巻き付けられることで撚り線9が得られる。そして、このように得られた撚り線9は回収装置90により回収される。 As shown in FIG. 1, a core line passage 11 a through which the core line 13 passes is formed at the central axis of the shaft member 11. For this reason, the core wire supply machine 80 which supplies the core wire 13 to the core wire channel | path 11a from the base end side of the shaft member 11 is further provided. Wires 32 fed from the plurality of nozzles 11 b are spirally wound around the core wire 13 supplied from the core wire feeder 80 and drawn out from the tip end of the shaft member 11. As described above, the plurality of wires 32 are spirally wound around the core wire 13 to obtain the stranded wire 9. The stranded wire 9 thus obtained is recovered by the recovery device 90.
 回収装置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、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、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、を有する。 The recovery device 90 is for winding the stranded wire 9 on the drum 91 at a constant speed, and the drum 91 for winding the stranded wire 9, a winding motor 92 for rotating the drum 91, and winding on the drum 91 And a recovery-side rotation sensor 94 formed of, for example, an encoder for detecting 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に対して直交するように基板96に取付けられる。ドラム91は、モータ92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、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、回収装置90を移動可能な複数のローラ97と、回収装置90を設置可能な支持脚98と、が設けられる。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。ここで、符号99で示される部材は、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、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である。 The motor 92 is attached to the substrate 96 so that its rotation axis 92 a is orthogonal to the central axis C 1 of the shaft member 11. The drum 91 is coaxially attached to the rotation shaft 92 a of the motor 92. Further, the recovery side speed detection pulley 93 is attached to the substrate 96 so that the stranded wire 9 to be wound is positioned on the extension of the core passage 11a. The substrate 96 is provided with a plurality of rollers 97 capable of moving the recovery device 90 and support legs 98 on which the recovery device 90 can be installed. The stranded wire 9 is wound around the recovery side speed detection pulley 93 and then wound around the drum 91. Here, the member denoted by reference numeral 99 sandwiches the stranded wire 9 together with the collection side speed detection pulley 93 so that the stranded wire 9 wound around the collection side speed detection pulley 93 does not come off the collection side speed detection pulley 93 It is a pinching roller 99.
 回収側回転センサ94の検出出力は制御装置であるコントローラ8に入力される。また、コントローラ8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、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。このため、コントローラ8は、撚り線9が等速でドラム91に巻き取られるように、回収側回転センサ94により検出される回収側速度検出プーリ93の回転速度が一定となるように巻き取りモータ92を制御する。 The detection output of the collection side rotation sensor 94 is input to a controller 8 which is a control device. The controller 8 is also connected to the winding motor 92. Here, the winding speed of the stranded wire 9 to the drum 91 is determined by the rotational speed of the collection side speed detection pulley 93 around which the stranded wire 9 is wound. Therefore, the controller 8 controls the winding motor so that the rotational speed of the collection side speed detection pulley 93 detected by the collection side rotation sensor 94 becomes constant so that the stranded wire 9 is wound around the drum 91 at a constant speed. Control 92
 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、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、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、を有する。 On the other hand, in the core wire feeder 80, a delivery spool 81 wound and wound with the core wire 13, a delivery motor 82 for rotating the delivery spool 81, and the core wire 13 unwound from the delivery spool 81 are wound. A supply-side speed detection pulley 83 and a supply-side rotation sensor 84, which is an encoder, for example, for detecting the rotational speed of the supply-side speed detection pulley 83 are provided.
 モータ82は、その回転軸82aが軸部材11の中心軸C1に対して直交するように基板86に取付けられる。繰り出しスプール81は、モータ82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、掛け回されて繰り出される芯線13が芯線通路11aに真っ直ぐ進入するように、芯線通路11aの延長線上に位置するように基板86に取付けられる。基板86には、芯線供給機80を移動可能な複数のローラ87と、芯線供給機80を設置可能な支持脚88と、が設けられる。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 such that its rotation axis 82 a is orthogonal to the central axis C 1 of the shaft member 11. The delivery spool 81 is coaxially attached to the rotation shaft 82 a of the motor 82. Further, the supply-side speed detection pulley 83 is attached to the base plate 86 so as to be positioned on the extension of the core passage 11a so that the core 13 wound and drawn out enters the core passage 11a straightly. The substrate 86 is provided with a plurality of rollers 87 capable of moving the core wire feeder 80 and support legs 88 on which the core wire feeder 80 can be installed. The core 13 unwound and fed out by the rotation of the delivery spool 81 is wound around the supply-side speed detection pulley 83, and then inserted into the core passage 11a.
 供給側回転センサ84の検出出力は制御装置であるコントローラ8に入力される。また、コントローラ8は、繰り出しモータ82に接続される。ここで、符号89で示される部材は、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、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である。 The detection output of the supply side rotation sensor 84 is input to the controller 8 which is a control device. The controller 8 is also connected to the feed motor 82. Here, the member indicated by reference numeral 89 is a pinching roller for pinching the core 13 together with the supply side speed detection pulley 83 so that the core 13 wound around the supply side speed detection pulley 83 does not come off the supply side speed detection pulley 83 89.
 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、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、繰り出しスプール81から芯線13を等速で巻解いて芯線通路11aに供給するように、供給側回転センサ84により検出される供給側速度検出プーリ83の回転速度が一定となるように繰り出しモータ82を制御する。 The delivery of the core 13 inserted into the core passage 11 a is performed by the rotation of the delivery spool 81 by the delivery motor 82, and the delivery speed is detected by the rotational speed of the supply-side speed detection pulley 83. The controller 8 unrolls the core wire 13 at a constant speed from the delivery spool 81 and supplies it to the core passage 11 a so that the rotational speed of the supply-side speed detection pulley 83 detected by the supply-side rotation sensor 84 becomes constant. The feed motor 82 is controlled.
 さらに、コントローラ8は、回収側速度検出プーリ93の回転速度により決まる撚り線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の繰り出し速度と、をそれぞれ求め、芯線13の繰り出し速度と撚り線9の巻き取り速度と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。これにより、芯線13の繰り出し及び撚り線9の巻き取りによって、スプール81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あっても、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ことができる。 Further, the controller 8 determines the collection speed of the stranded wire 9 determined by the rotation speed of the collection side speed detection pulley 93 and the feeding speed of the core 13 determined by the rotation speed of the supply side speed detection pulley 83 respectively. The winding motor 92 and the feeding motor 82 are respectively controlled so that the feeding speed and the winding speed of the stranded wire 9 become target values. Thereby, even if the outer diameter of the core wire 13 wound around the spool 81 and the outer diameter of the stranded wire 9 wound around the drum 91 change due to the unwinding of the core wire 13 and the winding of the stranded wire 9. The feeding speed of the core wire 13 and the winding speed of the twisted wire 9 can be maintained at target values.
 次に、線材撚り装置10を用いた撚り線9の製造方法について説明する。 Next, a method of manufacturing the stranded wire 9 using the wire strand twisting device 10 will be described.
 上記構成の線材撚り装置10を用いた撚り線9の製造方法では、軸部材11を中心として複数のスプール31を公転させ、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た複数の線材32を撚ることによって、撚り線9が製造される。また、軸部材11の中心軸C1に芯線13が通過する芯線通路11aが形成されているため、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ることによって芯線13を有する撚り線9が製造される。 In the method of manufacturing the stranded wire 9 using the wire stranding device 10 having the above configuration, the plurality of spools 31 are revolved around the shaft member 11 and the plurality of wire rods 32 unwound and drawn from the plurality of spools 31 are By twisting, a stranded wire 9 is produced. Further, since the core passage 11a through which the core wire 13 passes is formed at the central axis C1 of the shaft member 11, the core wire 13 is supplied from the base end side of the shaft member 11 to the core passage 11a while revolving the revolution body 23. A stranded wire 9 having a core 13 is produced by spirally winding a wire 32 around the core 13 drawn from the tip of the shaft member 11.
 具体的には、以下のような手順で撚り線9は製造される。 Specifically, the stranded wire 9 is manufactured by the following procedure.
 まず、芯線13が巻回されて貯線された繰り出しスプール81を用意し、繰り出しスプール81を繰り出しモータ82の回転軸82aに取り付ける。そして、繰り出しスプール81から巻解かれて芯線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に挿通させる。 First, the take-out spool 81 in which the core wire 13 is wound and stored is prepared, and the take-out spool 81 is attached to the rotation shaft 82 a of the take-out motor 82. Then, the core wire 13 is unwound from the delivery spool 81 and wound around the supply-side speed detection pulley 83, and then inserted into the core wire passage 11a.
 一方で、線材32が巻回されて貯線された複数のスプール31を用意し、複数の公転体23にこれらを取り付ける。具体的には、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、一対の係止棒36を互いに近づけてスプール31を両側から挟む。この結果、スプール31の中心軸C3が軸部材11の中心軸C1に対して直交するように、スプール31は公転体23により回転自在に支持される。そして、ハンドル棒38を係止フック39に係止させて係止棒36が互いに離間することを防止する。 On the other hand, a plurality of spools 31 wound and wound with a wire 32 are prepared, and these are attached to a plurality of revolving bodies 23. Specifically, the spool 31 is positioned between a pair of locking bars 36 separated from each other, and then the pair of locking bars 36 are brought close to each other to sandwich the spool 31 from both sides. As a result, the spool 31 is rotatably supported by the revolving body 23 such that the central axis C3 of the spool 31 is orthogonal to the central axis C1 of the shaft member 11. Then, the handle bar 38 is locked to the locking hook 39 to prevent the locking bars 36 from being separated from each other.
 次に、図2に示すように、スプール31から巻解かれた線材32を一対のローラ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に掛回して支持板22に回転自在に支持された枢支部材23dに挿通させる。枢支部材23dを挿通した線材32は張力付与機構60を介してノズル11bに挿通される。 Next, as shown in FIG. 2, the wire 32 unwound from the spool 31 is sandwiched between the pair of rollers 51, 51, and the wire 32 guided by the pair of rollers 51, 51 is applied to the plurality of pulleys 52, 52. The pivoting member 23 d rotatably supported by the support plate 22 is inserted into the support plate 22. The wire 32 having the pivoting member 23d inserted is inserted into the nozzle 11b through the tension applying mechanism 60.
 具体的には、枢支部材23dを挿通した線材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、軸部材11の先端に形成されたノズル11bに挿通させる。このように複数のノズル11bから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と共に回収装置90の回収側速度検出プーリ93に掛け回し、それらの端部をドラム91に係止させる。 Specifically, the wire 32 having the pivot member 23d inserted is sequentially wound around the first and second diverting pulleys 66 and 67, the wire guide 62, and the third and fourth diverting pulleys 68 and 71. The nozzle 11b formed at the tip is inserted. The wires 32 drawn from the nozzles 11 b are wound around the collecting side speed detection pulley 93 of the collecting device 90 together with the core 13 drawn from the tip of the shaft member 11, and their ends are the drum 91. Lock on.
 このような状態から、ドラム91が撚り線9を巻き取る回収速度と、芯線供給機80による芯線13の繰り出し速度と、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 such a state, the winding motor 92 and the feeding motor 82 are respectively controlled such that the collection speed at which the drum 91 winds the strand 9 and the feeding speed of the core 13 by the core feeder 80 become target values. Do.
 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、線材32が掛け回された線材ガイド62は第二及び第三プーリ67,68に近づく。このとき、張力付与機構60のテンションアーム61は回動し、その回動角はポテンショメータ64により検出される。 When the winding motor 92 rotates the drum 91 to wind and collect the plurality of wires 32 drawn from the nozzle 11b together with the core wire 13, the wire guide 62 wound with the wires 32 has the second and third pulleys 67 and 68. Approach to At this time, the tension arm 61 of the tension applying mechanism 60 is rotated, and the rotation angle is detected by the potentiometer 64.
 ポテンショメータ64の検出出力はコントローラ8に入力され、コントローラ8は、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各公転体23のモータ40の回転を制御する。この結果、各公転体23のスプール31から所定の張力が付与された線材32が順次繰り出される。 The detection output of the potentiometer 64 is input to the controller 8, and the controller 8 controls the rotation of the motor 40 of each of the revolving members 23 so that the rotation angle detected by the potentiometer 64 becomes a predetermined angle. As a result, the wire rod 32 to which a predetermined tension is applied is sequentially fed out from the spools 31 of the respective revolving members 23.
 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、軸部材11を中心として複数のスプール31を公転させる。そして、複数のスプール31からそれぞれ巻き解かれて軸部材11の複数のノズル11bから順次繰り出される複数の線材32が、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られることで撚り線9は製造される。そして、製造された撚り線9は、順次、ドラム91に巻き付けられて回収される。 As described above, in a state in which 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. Then, a plurality of wire rods 32 unwound from the plurality of spools 31 and sequentially drawn out from the plurality of nozzles 11 b of the shaft member 11 are spirally wound around the core wire 13 sequentially drawn out from the tip of the shaft member 11 The stranded wire 9 is manufactured at. And the manufactured stranded wire 9 is wound around the drum 91 one by one, and is collect | recovered.
 コントローラ8は、芯線13を繰り出す速度、撚り線9を巻き取る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き付けられる線材32の巻き付けピッチを均一にする。 The controller 8 controls the winding motor 92 and the unwinding motor 82 such that the speeds of unwinding the core wire 13 and the speeds of winding the twisted wire 9 become target values, and the rotational speed of the shaft member 11 is made uniform. The winding pitch of the wire 32 spirally wound around the core wire 13 is made uniform.
 ここで、撚り線9が製造されるとき、軸部材11の周囲において公転する複数の公転体23の自転は禁止される。公転体23の自転の禁止は、自転禁止機構25により行われる。また、張力付与機構60により付与された線材32の張力は、コントローラ8が、張力付与機構60のテンションアーム61の回動角が所定の角度となるように、モータ40を制御してスプール31を回転させることで、所定の値に維持される。 Here, when the stranded wire 9 is manufactured, rotation of the plurality of revolving bodies 23 revolving around the shaft member 11 is prohibited. The prohibition of the rotation of the revolving body 23 is performed by the rotation prohibition mechanism 25. The tension of the wire 32 applied by the tension applying mechanism 60 is controlled by the controller 8 by controlling the motor 40 so that the rotation angle of the tension arm 61 of the tension applying mechanism 60 becomes a predetermined angle. By rotating, it is maintained at a predetermined value.
 このように、本実施形態に係る線材撚り装置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に対して直交するように、スプール31が公転体23により回転自在に支持されるため、モータ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、線材32を軸部材11の長手方向に引き出すことができる。つまり、線材32はスプール31の円周方向に引き出されるため、引き出される際に線材32が捩られることがない。 As described above, in the wire stranding device 10 and the method of manufacturing a stranded wire according to the present embodiment, the spool 31 is perpendicular to the central axis C3 of the spool 31 for feeding the wire 32 with respect to the central axis C1 of the shaft member 11. Since it is rotatably supported by the revolving body 23, the wire 32 can be pulled out in the longitudinal direction of the shaft member 11 by rotating the spool 31 by the motor 40 and unwinding the wire 32. That is, since the wire 32 is pulled out in the circumferential direction of the spool 31, the wire 32 is not twisted when it is pulled out.
 よって、複数のスプール31から線材32を所望の速度で引き出して撚ることができる。このように捩られることなく引き出された線材32により得られた撚り線9は、所望の撚り状態が維持される。また、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, the wire 32 can be drawn out from the plurality of spools 31 at a desired speed and twisted. The stranded wire 9 obtained by the wire 32 drawn out without being twisted in this manner is maintained in the desired twisted state. Further, the degree of twisting does not locally differ, and it is possible to obtain a stranded wire 9 having a uniform degree of twisting.
 また、回転駆動機構がスプール31に並列に設けられたモータ40であるため、モータ40をスプール31の軸方向に設けた場合と比較して、公転体23の幅方向の寸法を小さくすることができる。この結果、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を回避することができる。 Further, since the rotational drive mechanism is the motor 40 provided parallel to the spool 31, the dimension in the width direction of the revolving body 23 can be reduced compared to the case where the motor 40 is provided in the axial direction of the spool 31. it can. As a result, it is possible to avoid the expansion of the revolution radius caused by the expansion of the dimension in the width direction of the revolving body 23.
 また、モータ40は、回転軸41aが同軸に連結された一対の小型モータ41,41から成る。このため、単一のモータによって同じ出力でスプール31を回転させる場合と比較して、モータ41,41の径方向の寸法を小さくすることができる。さらに、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ができる。このように、一対の小型モータ41,41を採用することで、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, the motor 40 is composed of a pair of small motors 41, 41 in which a rotation shaft 41a is coaxially connected. For this reason, compared with the case where the spool 31 is rotated with the same output by a single motor, the radial dimension of the motors 41 can be reduced. Furthermore, the dimension in the rotating shaft C2 direction of the revolving body 23 in which the motors 41 and 41 are provided can be made small. As described above, by adopting the pair of small motors 41, 41, the enlargement of the device 10 caused by the expansion of the revolution radius and the enlargement of the dimension of the revolving body 23 in the direction of the rotation axis C2 is avoided. be able to.
 また、複数のスプール31から巻解かれた複数の線材32に対して別々に所定の張力を加える複数の張力付与機構60が設けられているため、各ノズル11bから繰出される線材32のそれぞれの張力が略等しくなり、ノズル11bから繰出される線材32相互の張力ばらつきを抑制することができる。このように複数の線材32間の張力のばらつきが抑制されることで、所定のピッチで規則正しく撚られた撚り線9を得ることができる。 Further, since the plurality of tension applying mechanisms 60 for separately applying predetermined tension to the plurality of wires 32 unwound from the plurality of spools 31 is provided, each of the wires 32 delivered from each nozzle 11 b The tension becomes substantially equal, and it is possible to suppress the tension variation between the wires 32 delivered from the nozzle 11b. As described above, the variation in tension among the plurality of wires 32 is suppressed, so that it is possible to obtain the stranded wire 9 that is regularly twisted at a predetermined pitch.
 また、線材32が巻回されたスプール31の外径は、線材32が引き出されるのに従って小さくなる。もし、スプール31の回転速度が常に一定であれば、周方向に引き出される線材32の速度は、スプール31の外径に応じて変化することになる。このような線材32の引き出し速度の変化は、線材32の張力に影響を与える。これに対して、本実施形態においてスプール31の回転は、スプール31の外径に関わらず、張力付与機構60により線材32に付与される張力が一定となるように制御される。このようにスプール31の外径が変化した場合でも、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で、速度の変動に起因する悪影響を回避することができる。 Further, the outer diameter of the spool 31 around which the wire 32 is wound becomes smaller as the wire 32 is pulled out. If the rotational speed of the spool 31 is always constant, the speed of the wire 32 drawn in the circumferential direction will change according to the outer diameter of the spool 31. Such a change in the drawing speed of the wire 32 affects the tension of the wire 32. On the other hand, in the present embodiment, the rotation of the spool 31 is controlled so that the tension applied to the wire 32 by the tension applying mechanism 60 becomes constant regardless of the outer diameter of the spool 31. As described above, even when the outer diameter of the spool 31 changes, by maintaining the speed of the wire 32 drawn from the spool 31 at the target value, it is possible to avoid the adverse effect due to the fluctuation of the speed.
 また、引き出される線材32の速度に変動が生じ、スプール31の回転速度が、その変動に追従できなければ、線材32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32にあっては、線材32が引き千切られるおそれがある。これに対して、本実施形態では、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るため、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の引き千切りを線材32が比較的細い場合であっても回避することもできる。 In addition, if the speed of the drawn wire 32 fluctuates and the rotational speed of the spool 31 can not follow the fluctuation, the wire 32 can not be drawn at a desired speed, and the relatively thin wire 32 is As a result, the wire 32 may be broken. On the other hand, in the present embodiment, since the speed of the wire 32 drawn from the spool 31 can be maintained at the target value, the wire 32 is broken when it can not be drawn at a desired speed. Even if 32 is relatively thin, it can be avoided.
