The winding device 100 is a device that winds a wire rod 10 such as a metal wire drawn by a wire drawing machine or the like on a bobbin 120. The wire 10 is not limited to a drawn metal wire, and may be any wire that can be wound. For example, the wire 10 may be a wire made of a material that can be processed into a linear shape such as a resin, or a wire having a cross-sectional shape such as a circle, an ellipse, or a rectangle.
　ガイドローラ１１０は、所定の軸を中心に所定の面内で回転可能に構成されており、外部から受け取った線材１０を、ボビン１２０に対して送り出す。本実施形態において、ガイドローラ１１０は、ローラ本体１１２と、ローラ本体１１２の外周面１１４（ローラ外周面の一例である）に設けられた溝部１１６とを有して構成される。 The guide roller 110 is configured to be rotatable within a predetermined plane around a predetermined axis, and sends the wire 10 received from the outside to the bobbin 120.

　ローラ本体１１２は、所定の半径を有する円盤状の形状を有しており、回転軸１１８（第１回転軸の一例である）を中心に回転可能に構成されている。回転軸１１８は、一端がローラ本体１１２の略中心に取り付けられているとともに、他端がガイドローラ固定部１５０に固定さている。 The roller body 112 has a disc shape having a predetermined radius, and is configured to be rotatable around a rotation shaft 118 (an example of a first rotation shaft). The rotating shaft 118 has one end attached to the approximate center of the roller body 112 and the other end fixed to the guide roller fixing portion 150.
　また、ローラ本体１１２は、ローラ本体１１２の外周面１１４の近傍における厚さが、ローラ本体１１２の回転軸又は中心の近傍における厚さよりも薄くなるように構成されている。図１～３に示す形態において、ローラ本体１１２の幅は、中心から外周面１１４に向かうにつれて徐々に薄くなっているが、これに限られない。例えば、ローラ本体１１２は、ローラ本体１１２の中心から一定の距離にある領域において同じ厚さを有し、当該領域の外側において、外周面１１４に近づくにつれて厚さが薄くなるように構成されてもよい。 The roller body 112 is configured such that the thickness in the vicinity of the outer peripheral surface 114 of the roller body 112 is thinner than the thickness in the vicinity of the rotation axis or center of the roller body 112. In the form shown in FIGS. 1 to 3, the width of the roller main body 112 gradually decreases from the center toward the outer peripheral surface 114, but is not limited thereto. For example, the roller body 112 may have the same thickness in a region at a certain distance from the center of the roller body 112, and may be configured so that the thickness decreases as the outer peripheral surface 114 is approached outside the region. Good.
　溝部１１６は、ローラ本体１１２の外周面１１４において、外周面１１４からローラ本体の中心に向かう方向に、所定の深さを有するよう設けられている。溝部１１６は、線材１０を案内するのに十分な深さを有する。 The groove 116 is provided on the outer peripheral surface 114 of the roller main body 112 so as to have a predetermined depth in a direction from the outer peripheral surface 114 toward the center of the roller main body. The groove 116 has a depth sufficient to guide the wire 10.
　ボビン１２０は、所定の軸を中心に所定の面内で回転可能に構成されており、ガイドローラ１１０から送り出された線材１０を巻き取る。本実施形態において、ボビン１２０は、胴部１２４と、鍔部１２６及び１２８とを有して構成される。 The bobbin 120 is configured to be rotatable within a predetermined plane about a predetermined axis, and winds the wire 10 fed from the guide roller 110. In the present embodiment, the bobbin 120 is configured to include a body portion 124 and flange portions 126 and 128.
　胴部１２４は、筒状の形状を有しており、周方向に外周面１２５を有する。また、胴部１２４は、回転軸１２２（第２回転軸の一例である）を中心に回転可能に構成されている。回転軸１２２は、一端が胴部１２４に挿入されるとともに、他端がボビン回転部１９０に連結されている。 The barrel portion 124 has a cylindrical shape and has an outer peripheral surface 125 in the circumferential direction. The body portion 124 is configured to be rotatable around a rotation shaft 122 (which is an example of a second rotation shaft). One end of the rotating shaft 122 is inserted into the body portion 124, and the other end is connected to the bobbin rotating portion 190.
　ボビン回転部１９０は、例えば、モータ等の回転機構であり、回転軸１２２をｘｚ面内において回転させる。また、回転軸１２２には、ボビン１２０とボビン回転部１９０との間において、巻取軸部１９４が係合している。また、巻取軸部１９４は、ｙ軸方向に配置されたトラバース部１９６を摺動可能に設けられており、トラバース部１９６をｙ軸方向に移動することにより、回転軸１２２をｙ軸方向に移動させる。これにより、ｙ軸方向においてボビン１２０の位置を移動させることができるとともに、ｙ軸方向における、ボビン１２０に対するガイドローラ１１０の相対的な位置を移動させることができる。 The bobbin rotating unit 190 is a rotating mechanism such as a motor, for example, and rotates the rotating shaft 122 in the xz plane. Further, the winding shaft portion 194 is engaged with the rotating shaft 122 between the bobbin 120 and the bobbin rotating portion 190. The take-up shaft portion 194 is slidably provided on the traverse portion 196 disposed in the y-axis direction, and the rotary shaft 122 is moved in the y-axis direction by moving the traverse portion 196 in the y-axis direction.

　ボビン１２０は、回転軸１２２が延びる方向、すなわち、胴部１２４の回転面に対して略垂直な方向における、胴部１２４の両端に、それぞれ鍔部１２６及び１２８を有する。鍔部１２６及び１２８は、所定の半径を有する円盤形状を有しており、さらに、その中心部分に円形状の開口が設けられている。鍔部１２６及び１２８は、当該開口の周囲において回転軸１２２及び胴部１２４と連結されており、回転軸１２２が回転すると、胴部１２４とともに回転するよう構成されている。胴部１２４の外周面１２５は、胴部１２４が回転して線材１０が巻き付けられた際に、線材１０がスリップしにくいよう、例えば、外周面１２５よりも摩擦係数が高い材料により覆われている。 The bobbin 120 has flange portions 126 and 128 at both ends of the body portion 124 in the direction in which the rotation shaft 122 extends, that is, in the direction substantially perpendicular to the rotation surface of the body portion 124, respectively. The flanges 126 and 128 have a disk shape having a predetermined radius, and are further provided with a circular opening at the center thereof. The flanges 126 and 128 are connected to the rotating shaft 122 and the trunk portion 124 around the opening, and are configured to rotate together with the trunk portion 124 when the rotating shaft 122 rotates. The outer peripheral surface 125 of the trunk portion 124 is covered with, for example, a material having a higher friction coefficient than the outer peripheral surface 125 so that the wire rod 10 is less likely to slip when the trunk portion 124 rotates and the wire rod 10 is wound. .
　ガイドローラ１１０及びボビン１２０は、外周面１１４と外周面１２５が互いに対向するように配置されている。そして、ガイドローラ１１０及びボビン１２０は、図１におけるｘ軸方向及びｚ軸方向において、相対的な位置関係を変化させながら、ガイドローラ１１０の外周面１１４を通った線材１０を、ボビン１２０の外周面１２５に巻き付ける動作を行う。 The guide roller 110 and the bobbin 120 are arranged so that the outer peripheral surface 114 and the outer peripheral surface 125 face each other. The guide roller 110 and the bobbin 120 change the wire 10 that has passed the outer peripheral surface 114 of the guide roller 110 while changing the relative positional relationship in the x-axis direction and the z-axis direction in FIG. An operation of winding around the surface 125 is performed.
　ガイドローラ１１０及びボビン１２０は、それぞれの回転中心が図１におけるｘ軸方向、すなわち、ガイドローラ１１０の移動方向（図１におけるｚ方向）に略垂直な方向において略一致するように配置されている。すなわち、ガイドローラ１１０は、ガイドローラ１１０がｚ軸方向に移動した場合に、回転軸１１８の軌跡とボビン１２０の回転中心が、同一直線状に位置するように配置されている。 The guide roller 110 and the bobbin 120 are arranged so that their respective rotation centers substantially coincide with each other in the x-axis direction in FIG. 1, that is, in a direction substantially perpendicular to the moving direction of the guide roller 110 (z direction in FIG. 1). . That is, the guide roller 110 is disposed so that the locus of the rotation shaft 118 and the rotation center of the bobbin 120 are located in the same straight line when the guide roller 110 moves in the z-axis direction.
　ガイドローラ１１０は、ｚ軸方向において、回転軸１１８が鍔部１２６及び１２８の外周縁よりも外側に位置するように配置されている。すなわち、ガイドローラ１１０は、ｙ軸方向からガイドローラ１１０を見た場合に、回転軸１１８が、鍔部１２６及び１２８と重ならない位置に配置されている。また、ガイドローラ１１０は、外周面１１４の少なくとも一部が鍔部１２６及び１２８の外周縁よりも内側に位置するように配置されている。すなわち、ガイドローラ１１０は、ｙ軸方向からガイドローラ１１０を見た場合に、回転軸１１８が、鍔部１２６及び１２８と重なる位置に配置されている。 The guide roller 110 is disposed so that the rotation shaft 118 is positioned outside the outer peripheral edges of the flanges 126 and 128 in the z-axis direction. That is, the guide roller 110 is disposed at a position where the rotation shaft 118 does not overlap the flanges 126 and 128 when the guide roller 110 is viewed from the y-axis direction. Further, the guide roller 110 is arranged so that at least a part of the outer peripheral surface 114 is located inside the outer peripheral edges of the flanges 126 and 128. That is, the guide roller 110 is disposed at a position where the rotation shaft 118 overlaps the flanges 126 and 128 when the guide roller 110 is viewed from the y-axis direction.
　ガイドローラ移動部１３０は、ガイドローラ固定部１５０をｚ軸方向に移動させることにより、ガイドローラ固定部１５０に固定されたガイドローラ１１０をｚ軸方向に移動させる。具体的には、ガイドローラ移動部１３０は、モータ１３２及びボールネジ１３４を有しており、モータ１３２によってボールネジ１３４が回転し、ボールネジ１３４に係合したガイドローラ固定部１５０が、ボールネジ１３４が設けられた方向（すなわち、ｚ軸方向）に移動する。 The guide roller moving unit 130 moves the guide roller 110 fixed to the guide roller fixing unit 150 in the z-axis direction by moving the guide roller fixing unit 150 in the z-axis direction. Specifically, the guide roller moving unit 130 includes a motor 132 and a ball screw 134, and the ball screw 134 is rotated by the motor 132, and the guide roller fixing unit 150 engaged with the ball screw 134 is provided with the ball screw 134. (Ie, z-axis direction).
　ガイドローラ固定部１５０の一端には、ガイドローラ１６０が設けられている。ガイドローラ１６０は、ガイドローラ１１０と同様に、ローラ本体１６２、外周面１６４及び溝部１６６を有しており、回転軸１６８を中心に回転可能に構成されている。回転軸１６８は、一端がローラ本体１６２の略中心に取り付けられているとともに、他端がガイドローラ固定部１５０の一端に固定されている。 A guide roller 160 is provided at one end of the guide roller fixing portion 150. Similar to the guide roller 110, the guide roller 160 includes a roller main body 162, an outer peripheral surface 164, and a groove portion 166, and is configured to be rotatable around a rotation shaft 168. One end of the rotating shaft 168 is attached to the approximate center of the roller body 162, and the other end is fixed to one end of the guide roller fixing portion 150.
　ガイドローラ１６０は、ｙ軸報告において、溝部１６６が、ガイドローラ１１０の溝部１１６と重なるように、ガイドローラ固定部１５０に固定される。そして、ガイドローラ１６０は、巻取装置１００の外部において送り出された線材１０を溝部１６６において案内するとともに、ガイドローラ１１０に送り出す。 The guide roller 160 is fixed to the guide roller fixing portion 150 so that the groove portion 166 overlaps the groove portion 116 of the guide roller 110 in the y-axis report. The guide roller 160 guides the wire 10 delivered outside the winding device 100 in the groove portion 166 and sends it to the guide roller 110.
　ガイドローラ固定部１５０の他端には、ガイドローラ角度制御部１４０が設けられている。ガイドローラ角度制御部１４０は、例えばモータなどの回転機構を有しており、その回転軸ａを中心として、ガイドローラ固定部１５０をｙｚ面内で回転させて、ボビン１２０の外周面１２５に対するガイドローラ１１０の傾きを調整する。 A guide roller angle control unit 140 is provided at the other end of the guide roller fixing unit 150. The guide roller angle control unit 140 has a rotation mechanism such as a motor, for example, and rotates the guide roller fixing unit 150 in the yz plane around the rotation axis a to guide the outer peripheral surface 125 of the bobbin 120. The inclination of the roller 110 is adjusted.
　巻取装置１００は、ボビン１２０とガイドローラ角度制御部１４０との間において、投光部１７０を有する。本実施形態において、投光部１７０は、レーザ光を発する発光装置である。当該レーザ光は、例えば、長手方向がｙ軸方向、短手方向がｚ軸方向となる、帯状のレーザ光である。また、投光部１７０は、投光部１７０が発するレーザ光のｙ軸方向における光軸ｂが、ガイドローラ角度制御部１４０の回転軸ａと略一致するように設けられている。例えば、当該レーザ光が、ｙ軸方向に所定の幅を有する帯状のレーザ光である場合、ｙ軸方向における当該レーザ光の略中心を、当該レーザ光の光軸としてもよい。また、ガイドローラ１１０及び投光部１７０は、投光部１７０が発したレーザ光が、ガイドローラ１１０からボビン１２０に送り出された線材１０に照射され得るように配置される。具体的には、投光部１７０は、投光部１７０が発したレーザ光がガイドローラ１１０の外周面１１４とボビン１２０との間を通過するように配置される。 The winding device 100 includes a light projecting unit 170 between the bobbin 120 and the guide roller angle control unit 140. In the present embodiment, the light projecting unit 170 is a light emitting device that emits laser light. The laser beam is, for example, a strip-shaped laser beam in which the longitudinal direction is the y-axis direction and the short direction is the z-axis direction. The light projecting unit 170 is provided such that the optical axis b in the y-axis direction of the laser light emitted from the light projecting unit 170 substantially coincides with the rotation axis a of the guide roller angle control unit 140. For example, when the laser beam is a strip-shaped laser beam having a predetermined width in the y-axis direction, the approximate center of the laser beam in the y-axis direction may be the optical axis of the laser beam. Further, the guide roller 110 and the light projecting unit 170 are arranged so that the laser beam emitted from the light projecting unit 170 can be applied to the wire rod 10 sent from the guide roller 110 to the bobbin 120. Specifically, the light projecting unit 170 is disposed so that the laser light emitted from the light projecting unit 170 passes between the outer peripheral surface 114 of the guide roller 110 and the bobbin 120.
　また、巻取装置１００は、ボビン１２０を挟んで投光部１７０と反対側に、受光部１８０を有する。受光部１８０は、光軸ｂ上に設けられており、投光部１７０が発したレーザ光を受光する。受光移動部１８２は、受光部１８０と係合しており、ｚ軸方向における投光部１７０の位置に応じて、ｚ軸方向において受光部１８０を移動するよう構成されている。そして、受光部１８０は、例えば、当該レーザ光がガイドローラ１１０から送り出された線材１０に照射されて、その一部が受光部１８０に到達しなかった場合、受光部１８０においてレーザ光が受光されなかった位置を示す受光信号を出力する。なお、投光部１７０が本実施形態における受光部１８０の位置に、また、受光部１８０が本実施形態における投光部１７０の位置に配置されてもよい。 Further, the winding device 100 has a light receiving unit 180 on the opposite side of the light projecting unit 170 with the bobbin 120 interposed therebetween. The light receiving unit 180 is provided on the optical axis b, and receives the laser light emitted from the light projecting unit 170. The light receiving / moving unit 182 is engaged with the light receiving unit 180 and is configured to move the light receiving unit 180 in the z-axis direction according to the position of the light projecting unit 170 in the z-axis direction. For example, when the laser beam is irradiated on the wire 10 sent out from the guide roller 110 and a part of the light does not reach the light receiving unit 180, the light receiving unit 180 receives the laser light. A light reception signal indicating the position where there was not is output. The light projecting unit 170 may be disposed at the position of the light receiving unit 180 in the present embodiment, and the light receiving unit 180 may be disposed at the position of the light projecting unit 170 in the present embodiment.
　図４は、巻取装置１００の制御構成を示すブロック図である。巻取装置１００は、巻取装置１００の各構成を統括的に制御する制御部２００をさらに備える。制御部２００は、ガイドローラ移動部１３０、ガイドローラ角度制御部１４０、ボビン回転部１９０、ボビン移動部１９２、投光部１７０及び受光部１８０に接続される。また、巻取装置１００を制御する制御プログラムを備え、当該制御プログラムに基づいて、制御部２００に接続された各構成を制御する。 FIG. 4 is a block diagram showing a control configuration of the winding device 100. The winding device 100 further includes a control unit 200 that comprehensively controls each component of the winding device 100. The control unit 200 is connected to the guide roller moving unit 130, the guide roller angle control unit 140, the bobbin rotating unit 190, the bobbin moving unit 192, the light projecting unit 170, and the light receiving unit 180. Moreover, the control program which controls the winding apparatus 100 is provided, and each structure connected to the control part 200 is controlled based on the said control program.
　図５は、ガイドローラ１１０から送り出された線材１０がボビン１２０に巻き取られる動作を模式的に示した図である。以下、図１～５を参照して、巻取装置１００の動作について説明する。なお、以下では、線材１０の先端がボビン１２０の外周面１２５のうち鍔部１２６に最も近い部分に固定された状態から、線材１０をボビン１２０に巻き取る例について説明する。 FIG. 5 is a diagram schematically showing an operation in which the wire 10 delivered from the guide roller 110 is wound around the bobbin 120. Hereinafter, the operation of the winding device 100 will be described with reference to FIGS. In the following, an example in which the wire 10 is wound around the bobbin 120 from a state in which the tip of the wire 10 is fixed to a portion of the outer peripheral surface 125 of the bobbin 120 closest to the flange 126 will be described.
　まず、制御部２００は、予め与えられたガイドローラ１１０の回転半径や位置等の情報に基づいて、ｚ軸方向における、ボビン１２０の外周面１２５の対するガイドローラ１１０の位置を制御する。制御部２００は、例えば、ガイドローラ１１０の外周面１１４とボビン１２０の外周面１２５との距離が、予め定められた距離となるように、ガイドローラ移動部１３０を制御して、ｚ軸方向におけるガイドローラ１１０の位置を制御する。制御部２００は、ガイドローラ１１０の外周面１１４又は溝部１１６に案内された線材１０が、ボビン１２０の外周面１２５に接するか、外周面１２５を押圧するようにガイドローラ移動部１３０を制御してもよい。 First, the control unit 200 controls the position of the guide roller 110 with respect to the outer peripheral surface 125 of the bobbin 120 in the z-axis direction based on information such as the rotation radius and position of the guide roller 110 given in advance. For example, the control unit 200 controls the guide roller moving unit 130 so that the distance between the outer peripheral surface 114 of the guide roller 110 and the outer peripheral surface 125 of the bobbin 120 is a predetermined distance, and thereby the z-axis direction is controlled. The position of the guide roller 110 is controlled. The control unit 200 controls the guide roller moving unit 130 so that the wire 10 guided by the outer peripheral surface 114 or the groove 116 of the guide roller 110 is in contact with or presses the outer peripheral surface 125 of the bobbin 120. Also good.
　また、制御部２００は、予め与えられた情報に基づいて、ボビン１２０の外周面１２５に対するガイドローラ１１０の傾きを制御する。具体的には、制御部２００は、ガイドローラ１１０の外周面１１４がボビン１２０の外周面１２５のうち鍔部１２６に最も近い部分に位置する場合に、ｚ軸、すなわち、ボビン１２０の外周面１２５に略垂直な方向に対するガイドローラ１１０の角度（すなわち、ボビン１２０の回転面に対するガイドローラ１１０の回転面の角度。以下、「ガイドローラ１１０の角度」という。）をθにするという情報を予め記憶している。そして、制御部２００は、当該情報に基づいて、ガイドローラ１１０の角度がθになるように、ガイドローラ角度制御部１４０を制御する。 Further, the control unit 200 controls the inclination of the guide roller 110 with respect to the outer peripheral surface 125 of the bobbin 120 based on information given in advance. Specifically, when the outer peripheral surface 114 of the guide roller 110 is located at a portion of the outer peripheral surface 125 of the bobbin 120 that is closest to the flange 126, the control unit 200 detects the z axis, that is, the outer peripheral surface 125 of the bobbin 120. The information that the angle of the guide roller 110 with respect to the direction substantially perpendicular to the angle (that is, the angle of the rotation surface of the guide roller 110 with respect to the rotation surface of the bobbin 120; hereinafter referred to as “the angle of the guide roller 110”) is θ is stored in advance. is doing. Based on the information, the control unit 200 controls the guide roller angle control unit 140 so that the angle of the guide roller 110 becomes θ.
　また、制御部２００は、予め与えられた情報に基づいて、ｙ軸方向における、外周面１２５に対するガイドローラ１１０の相対的な位置を制御する。制御部２００は、ｙ軸方向において、ガイドローラ１１０の外周面１１４が、ボビン１２０の外周面１２５のうち鍔部１２６に最も近い部分に位置するように、ボビン移動部１９２を制御する。 Further, the control unit 200 controls the relative position of the guide roller 110 with respect to the outer peripheral surface 125 in the y-axis direction based on information given in advance. The control unit 200 controls the bobbin moving unit 192 so that the outer peripheral surface 114 of the guide roller 110 is positioned in the portion of the outer peripheral surface 125 of the bobbin 120 that is closest to the flange 126 in the y-axis direction.
　次に、制御部２００は、ボビン１２０を回転させて、線材１０の巻き取りを開始する。制御部２００は、ボビン回転部１９０を制御してボビン１２０を回転させるとともに、線材１０が所定の間隔で外周面１２５に巻き付けられるように、ボビン移動部１９２を制御して、ｙ軸方向においてボビン１２０を移動させる。 Next, the control unit 200 rotates the bobbin 120 and starts winding the wire 10. The control unit 200 controls the bobbin rotating unit 190 to rotate the bobbin 120 and also controls the bobbin moving unit 192 so that the wire 10 is wound around the outer peripheral surface 125 at a predetermined interval. 120 is moved.
　制御部２００は、線材１０の巻き始め、すなわち、ガイドローラ１１０が鍔１２６の近傍に位置する場合、図５（Ａ）に示すように、ｙ軸方向において、ガイドローラ１１０から送り出された線材１０がボビン１２０に巻かれた線材１０よりも鍔１２６から所定の距離、離れた部分に位置するように、ボビン移動部１９２を制御してもよい。当該所定の距離は、例えば、線材１０の半径から直径程度の距離である。 The control unit 200 starts the winding of the wire 10, that is, when the guide roller 110 is positioned in the vicinity of the flange 126, as shown in FIG. 5A, the wire 10 delivered from the guide roller 110 in the y-axis direction. The bobbin moving unit 192 may be controlled such that the bobbin moving part 192 is located at a predetermined distance from the rod 126 with respect to the wire rod 10 wound around the bobbin 120. The predetermined distance is, for example, a distance from the radius of the wire 10 to the diameter.
　そして、制御部２００は、線材１０が外周面１２５に密に巻き付けられるように、すなわち、ｙ軸方向において隣接する線材１０同士が接した状態で外周面１２５に巻き付けられるように、ボビン移動部１９２を制御する。具体的には、制御部２００は、図５（Ｂ）に示すように、線材１０の巻き付け方向（外周面１２５において線材１０が巻き付けられていく方向、すなわち、ｙ軸方向において鍔１２６から鍔１２８に向かう方向）において、ガイドローラ１１０から送り出された線材１０（すなわち、ガイドローラ１１０とボビン１２０との間に位置する線材１０）がボビン１２０に巻かれた線材１０よりも鍔１２６側に位置するように（すなわち、巻き付けられた線材１０がガイドローラ１１０から送り出された線材１０よりも先行するように）、ボビン移動部１９２を制御する。これにより、ガイドローラ１１０から送り出された線材１０が外周面１２５に巻き付けられる際に、外周面１２５に既に巻き付けられた線材１０に対して、巻き付け方向と反対の方向に力を加えることができるため、線材１０を外周面１２５において密に巻き付けることができる。 And the control part 200 is the bobbin moving part 192 so that the wire 10 may be tightly wound around the outer peripheral surface 125, that is, so that the wire 10 adjacent to each other in the y-axis direction is wound around the outer peripheral surface 125. To control. Specifically, as shown in FIG. 5B, the control unit 200 winds the wire 10 in the winding direction (the direction in which the wire 10 is wound on the outer peripheral surface 125, that is, the y-axis direction, from the flange 126 to the flange 128. In the direction toward the center), the wire 10 delivered from the guide roller 110 (that is, the wire 10 positioned between the guide roller 110 and the bobbin 120) is positioned closer to the flange 126 than the wire 10 wound around the bobbin 120. The bobbin moving unit 192 is controlled as described above (that is, the wound wire 10 precedes the wire 10 fed from the guide roller 110). Thereby, when the wire 10 delivered from the guide roller 110 is wound around the outer peripheral surface 125, a force can be applied to the wire 10 already wound around the outer peripheral surface 125 in a direction opposite to the winding direction. The wire 10 can be tightly wound around the outer peripheral surface 125.
　なお、制御部２００は、図５（Ａ）に示す状態から図５（Ｂ）に示す状態になるように、線材１０がボビン１２０の外周面１２５に巻かれるにつれて、ｙ軸方向における、ガイドローラ１１０から送り出された線材１０とボビン１２０の外周面１２５に既に巻き付けられた線材１０との相対的な位置関係が徐々に変化するように、ボビン移動部１９２を制御する。 Note that the control unit 200 guides the guide roller in the y-axis direction as the wire 10 is wound around the outer peripheral surface 125 of the bobbin 120 so that the state shown in FIG. 5A is changed to the state shown in FIG. The bobbin moving unit 192 is controlled so that the relative positional relationship between the wire 10 delivered from 110 and the wire 10 already wound around the outer peripheral surface 125 of the bobbin 120 gradually changes.
　このとき、制御部２００は、受光部１８０が出力した受光信号に基づいて、ｙ軸方向における、ガイドローラ１１０から送り出された線材１０とボビン１２０の外周面１２５に既に巻き付けられた線材１０との相対的な位置関係を判断し、さらに、当該位置関係に基づいて、ボビン移動部１９２を制御する。これにより、例えば、線材１０の実際の太さや、外周面１２５において線材１０が実際に巻かれた位置に応じて、ガイドローラ１１０とボビン１２０との相対的な位置関係を制御できる。従って、例えば、線材１０の太さに誤差があったとしても、線材１０をボビン１２０に巻くにつれて、当該誤差が累積することを防げるので、線材１０を密に巻くことができる。 At this time, based on the light reception signal output from the light receiving unit 180, the control unit 200 determines whether the wire 10 sent from the guide roller 110 and the wire 10 already wound around the outer peripheral surface 125 of the bobbin 120 in the y-axis direction. The relative positional relationship is determined, and the bobbin moving unit 192 is controlled based on the positional relationship. Thereby, for example, the relative positional relationship between the guide roller 110 and the bobbin 120 can be controlled according to the actual thickness of the wire 10 and the position where the wire 10 is actually wound on the outer peripheral surface 125. Therefore, for example, even if there is an error in the thickness of the wire 10, it is possible to prevent the error from accumulating as the wire 10 is wound around the bobbin 120, so that the wire 10 can be tightly wound.
　また、制御部２００は、ｙ軸方向における、外周面１２５に対するガイドローラ１１０の相対的な位置に応じて、ガイドローラ１１０の角度を制御する。制御部２００は、例えば、ｙ軸方向において、ガイドローラ１１０の外周面１１４の位置が外周面１２５の端部の近傍にあるときのガイドローラ１１０の角度をθとし、ガイドローラ１１０の外周面１１４の位置が外周面１２５の中心にあるときのガイドローラ１１０の角度をゼロとした場合、ガイドローラ１１０の外周面１１４が、外周面１２５の端部から中心部に向かうにつれて、ガイドローラ１１０の角度がθから徐々にゼロに近づくようにガイドローラ角度制御部１４０を制御する。 Further, the control unit 200 controls the angle of the guide roller 110 according to the relative position of the guide roller 110 with respect to the outer peripheral surface 125 in the y-axis direction. For example, the controller 200 sets the angle of the guide roller 110 when the position of the outer peripheral surface 114 of the guide roller 110 is near the end of the outer peripheral surface 125 in the y-axis direction as θ, and the outer peripheral surface 114 of the guide roller 110. When the angle of the guide roller 110 when the position of the guide roller 110 is at the center of the outer peripheral surface 125 is zero, the angle of the guide roller 110 increases as the outer peripheral surface 114 of the guide roller 110 moves from the end of the outer peripheral surface 125 toward the central portion. The guide roller angle control unit 140 is controlled so as to gradually approach zero from θ.
　そして、制御部２００は、ｙ軸方向において、ガイドローラ１１０の外周面１１４が、外周面１２５の中心を通過して、鍔部１２８の近傍に向かうにつれて、ガイドローラ１１０の角度が徐々にθに近づくように、ガイドローラ角度制御部１４０を制御する。これにより、図５（Ｃ）に示すように、ボビン１２０の外周面１２５において、鍔部１２６の近傍から鍔部１２８の近傍まで線材１０が巻き付けられた状態となる。 Then, in the y-axis direction, the control unit 200 gradually increases the angle of the guide roller 110 to θ as the outer peripheral surface 114 of the guide roller 110 passes through the center of the outer peripheral surface 125 and approaches the vicinity of the flange portion 128. The guide roller angle control unit 140 is controlled so as to approach. As a result, as shown in FIG. 5C, the wire 10 is wound from the vicinity of the flange 126 to the vicinity of the flange 128 on the outer peripheral surface 125 of the bobbin 120.
　次に、巻取装置１００が、ボビン１２０の外周面１２５に巻き付けられた線材１０の表面に、さらに線材１０を巻き付ける動作について説明する。 Next, an operation in which the winding device 100 further winds the wire 10 around the surface of the wire 10 wound around the outer peripheral surface 125 of the bobbin 120 will be described.
　制御部２００は、ボビン１２０の外周面１２５に巻き付けられた線材１０の表面の高さに応じて、ｚ軸方向における、ボビン１２０の外周面１２５の対するガイドローラ１１０の位置を制御する。図５に示す例では、ボビン１２０の外周面１２５に線材１０が密に巻き付けられており、制御部２００は、ガイドローラ１１０の外周面１１４がボビン１２０の外周面１２５から、線材１０の直径と同じ距離さらに離れるように、ガイドローラ移動部１３０を制御する。このとき、制御部２００は、投光部１７０が発したレーザ光を受光部１８０にて受光できるように、ガイドローラ１１０の移動に合わせて、受光移動部１８２を制御して、ｚ軸方向における受光部１８０の位置を制御する。 The control unit 200 controls the position of the guide roller 110 relative to the outer peripheral surface 125 of the bobbin 120 in the z-axis direction according to the height of the surface of the wire 10 wound around the outer peripheral surface 125 of the bobbin 120. In the example illustrated in FIG. 5, the wire 10 is tightly wound around the outer peripheral surface 125 of the bobbin 120, and the control unit 200 determines that the outer peripheral surface 114 of the guide roller 110 is from the outer peripheral surface 125 of the bobbin 120. The guide roller moving unit 130 is controlled so as to be further separated by the same distance. At this time, the control unit 200 controls the light receiving / moving unit 182 in accordance with the movement of the guide roller 110 so that the laser beam emitted from the light projecting unit 170 can be received by the light receiving unit 180. The position of the light receiving unit 180 is controlled.
　そして、制御部２００は、図５（Ａ）～（Ｃ）と同様の動作を繰り返し、図５（Ｄ）に示すように、ボビン１２０の外周面１２５に巻き付けられた線材１０の表面に、さらに線材１０を巻き付けることができる。なお、ガイドローラ１１０から送り出された線材１０は、外周面１２５に既に巻き付けられた隣接する線材１０間に形成される窪みに位置するように、ボビン１２０に巻き付けられてもよい。 Then, the control unit 200 repeats the same operation as that shown in FIGS. 5A to 5C, and as shown in FIG. 5D, further on the surface of the wire 10 wound around the outer peripheral surface 125 of the bobbin 120. The wire 10 can be wound. The wire rod 10 fed out from the guide roller 110 may be wound around the bobbin 120 so as to be positioned in a recess formed between adjacent wire rods 10 already wound around the outer peripheral surface 125.
　本実施形態の巻取装置１００によれば、ガイドローラ１１０から線材１０が送り出される位置を、ボビン１２０の胴部１２４の近傍に配置することができる。また、本実施形態の巻取装置１００によれば、ガイドローラ１１０から線材１０が送り出される位置と、当該線材１０がボビン１２０において巻き取られる位置を所望の位置関係に保つことができる。さらに、本実施形態に係る巻取装置１００によれば、ボビン１２０の胴部１２４の両端まで線材１０を密に巻き付けることができる。 According to the winding device 100 of the present embodiment, the position where the wire 10 is fed from the guide roller 110 can be disposed in the vicinity of the body portion 124 of the bobbin 120. Further, according to the winding device 100 of the present embodiment, the position where the wire 10 is fed from the guide roller 110 and the position where the wire 10 is wound on the bobbin 120 can be maintained in a desired positional relationship. Furthermore, according to the winding device 100 according to the present embodiment, the wire 10 can be tightly wound up to both ends of the body portion 124 of the bobbin 120.
