　線材の製造工程において、ボビンに線材を巻き取る装置が用いられている。この巻取装置は、ボビンを回転させつつ該ボビンの軸方向に往復移動させることで、ボビンに線材を多層整列巻き可能に構成されている。具体的には、この巻取装置は、回転するボビンの胴部に軸方向一端側から他端側へと線材を整列して巻き取り、ボビンの鍔部に接する位置で線材を既存層から層上がりさせ、その後層上がりした位置からボビンを反転させて軸方向に線材を整列して巻き取りを行うことで線材を多層整列巻きする。 An apparatus for winding a wire around a bobbin is used in the manufacturing process of the wire. This winding device is configured such that a wire rod can be wound in multiple layers on a bobbin by reciprocating in the axial direction of the bobbin while rotating the bobbin. Specifically, this winding device arranges and winds the wire from the axial end to the other end of the rotating bobbin body, and the wire is layered from the existing layer at a position in contact with the bobbin collar. Then, the bobbin is reversed from the position where the layer is raised, and the wire is aligned and wound in the axial direction, whereby the wire is wound in multiple layers.
　しかしながら、この巻取装置は、線材の既存層からの層上がり位置でボビンの鍔部及び線材の間に間隔が生じたり、隣接する線材間に重なり合いが生じたりするおそれがある。 However, this winding device may cause a gap between the bobbin buttock and the wire at the layer rising position from the existing layer of the wire, or overlap between adjacent wires.
　このような問題に基づいて、今日では「平角線の巻取装置および巻取方法」が発案されている（特開２０１０－６５８５号公報参照）。この公報に記載の巻取装置は、ボビンの往復移動速度を可変に制御すると共に、線押えローラで線材を押えることにより線材及びボビンの鍔部の間隔、並びに線材同士の隙間を減少させることで、線材間、又は線材及び鍔部間の間隔を調整して隣接する線材間の重なり合いを抑制することができる。 Based on these problems, a “flat wire winding device and winding method” have been proposed today (see Japanese Patent Application Laid-Open No. 2010-6585). The winding device described in this publication variably controls the reciprocating speed of the bobbin, and reduces the gap between the wire and the bobbin ridge and the gap between the wires by pressing the wire with a wire holding roller. By adjusting the interval between the wire rods or between the wire rod and the collar portion, the overlap between the adjacent wire rods can be suppressed.

The winding device described in the above publication has a problem that it is difficult to prevent the wire rod from climbing (wire riding) and the wire rod from dropping (wire dropping) due to disturbance. Specifically, this winding device corresponds to a convex portion when irregularities are formed on the inner surface of the bobbin collar (surface on the body side of the bobbin) due to thermal deformation during use. The wire rod hits the buttock faster than the setting at the part, or the space between the wire rod and the buttock increases at the part corresponding to the recess, and the wire rod at the climbing part falls to the buttock side and the line drop occurs. May occur. Further, when such wire riding or wire dropping occurs, there is a high possibility that further wire riding or wire dropping will occur in the subsequent winding process of the wire.

　上記課題を解決するためになされた本発明の一態様に係る巻取装置は、円筒状の胴部及びその両側の鍔部を有するボビンを該ボビンの軸方向に往復移動させるボビン駆動機構を備え、該ボビンに線材を多層整列巻きする巻取装置であって、該ボビンを胴部の接線方向から撮影するカメラと、上記カメラが撮影した画像に基づいて該ボビンの往復移動のタイミングを設定する制御部とを備える。 [Description of Embodiment of the Present Invention]
A winding device according to an aspect of the present invention made to solve the above-described problem includes a bobbin driving mechanism that reciprocally moves a bobbin having a cylindrical body portion and flanges on both sides thereof in the axial direction of the bobbin. A winding device for winding the bobbins in a multi-layered arrangement, wherein the bobbin is photographed from the tangential direction of the body, and the reciprocating timing of the bobbin is set based on an image photographed by the camera. And a control unit.
　当該巻取装置は、ボビンを胴部の接線方向から撮影するカメラを備えており、このカメラは既存層への線材の乗り上がり画像を撮影することができる。また、当該巻取装置は、このカメラが撮影した画像に基づいてボビンの往復移動のタイミングを設定する制御部を備えるので、線材の乗り上がりに基づいてボビンの往復移動を制御することができる。当該巻取装置は、規定のプログラムによってボビンを往復移動させるものではなく、線材の乗り上がりに基づいて（つまり、実測データに基づいて）ボビンの往復移動を制御するものであるので、ボビンの鍔部の内面に凹凸が形成されていた場合でもこの凹凸に基づく線乗り及び線落ちを抑制し易い。そのため、当該巻取装置は、線材の線乗りや線落ちを容易かつ確実に抑制することができる。 The winding device is equipped with a camera that photographs the bobbin from the tangential direction of the trunk, and this camera can photograph an image of the wire rod on the existing layer. Further, since the winding device includes a control unit that sets the timing of the reciprocating movement of the bobbin based on the image taken by the camera, the reciprocating movement of the bobbin can be controlled based on the climbing of the wire rod. The winding device does not reciprocate the bobbin according to a prescribed program, but controls the reciprocating movement of the bobbin based on the climbing of the wire (that is, based on measured data). Even when unevenness is formed on the inner surface of the portion, it is easy to suppress line riding and line dropping based on the unevenness. Therefore, the winding device can easily and reliably suppress the wire riding and wire dropping of the wire.
　当該巻取装置は、上記線材に対するボビンの鍔部の軸方向間隔を測定する変位センサーをさらに備えるとよい。このように、上記線材に対するボビンの鍔部の軸方向間隔を測定する変位センサーをさらに備えることによって、線材及び鍔部の軸方向間隔に基づいてボビンの往復移動をより的確に制御することができる。 The winding device may further include a displacement sensor for measuring an axial distance of the bobbin collar relative to the wire. Thus, by further providing a displacement sensor that measures the axial distance between the bobbin collar relative to the wire rod, the reciprocation of the bobbin can be more accurately controlled based on the axial distance between the wire rod and the collar portion. .
　当該巻取装置は、上記線材が上記ボビンに巻き取られる際に線材を鍔部側に付勢する線材整列機構をさらに備え、上記変位センサーがこの線材整列機構に取り付けられているとよい。このように、上記ボビンに巻き取られる際に線材を鍔部側に付勢する線材整列機構をさらに備え、上記変位センサーがこの線材整列機構に取り付けられていることによって、線材及び鍔部の軸方向間隔を容易かつ確実に測定することができる。 The winding device may further include a wire rod alignment mechanism that biases the wire rod toward the buttocks when the wire rod is wound around the bobbin, and the displacement sensor may be attached to the wire rod alignment mechanism. As described above, the wire rod alignment mechanism further biases the wire rod toward the flange portion when being wound around the bobbin, and the displacement sensor is attached to the wire rod alignment mechanism. The direction interval can be measured easily and reliably.
　上記制御部が、既存層への上記線材の乗り上がり位置を基準としてボビンが１５０°以上３００°以下回転したときにボビンを反転移動させるとよい。このように、上記制御部が、既存層への上記線材の乗り上がり位置を基準としてボビンが上記範囲の角度で回転したときにボビンを反転移動させることによって、層上がりした位置の外面と層上がりした位置以外の外面との平坦化を促進することができ、巻き取り後に線材をスムーズに繰り出すことができる。 The control unit may reversely move the bobbin when the bobbin rotates 150 ° or more and 300 ° or less with reference to the position where the wire rods on the existing layer. In this way, the control unit reversely moves the bobbin when the bobbin rotates at an angle in the above range with respect to the position where the wire rods on the existing layer as a reference. It is possible to promote flattening with the outer surface other than the position, and the wire can be smoothly fed out after winding.
　また、上記課題を解決するためになされた別の発明は、円筒状の胴部及びその両側の鍔部を有するボビンを該ボビンの軸方向に往復移動させ、該ボビンに線材を多層整列巻きする巻取方法であって、ボビンを胴部の接線方向から撮影する撮影工程と、上記撮影工程で撮影した画像に基づいてボビンの往復移動のタイミングを設定する制御工程とを備える。 Another invention made in order to solve the above-mentioned problem is to reciprocate a bobbin having a cylindrical body portion and flanges on both sides thereof in the axial direction of the bobbin, and wind the wire rods in a multi-layered manner around the bobbin. A winding method, which includes a photographing step of photographing the bobbin from a tangential direction of the body portion, and a control step of setting the timing of the reciprocating movement of the bobbin based on the image photographed in the photographing step.
　当該巻取方法は、ボビンを胴部の接線方向から撮影する撮影工程を備えるので、撮影工程によって既存層への線材の乗り上がり画像を撮影することができる。また、当該巻取方法は、撮影工程で撮影した画像に基づいてボビンの往復移動のタイミングを設定する制御工程を備えるので、線材の乗り上がりに基づいてボビンの往復移動を制御することができる。そのため、当該巻取方法は、既述のように線材の線乗りや線落ちを容易かつ確実に抑制することができる。 Since the winding method includes a photographing process of photographing the bobbin from the tangential direction of the body part, it is possible to photograph a climbing image of the wire on the existing layer by the photographing process. In addition, since the winding method includes a control process for setting the timing of the reciprocating movement of the bobbin based on the image captured in the imaging process, the reciprocating movement of the bobbin can be controlled based on the climbing of the wire rod. Therefore, the winding method can easily and surely suppress the wire riding and wire dropping of the wire as described above.

　以下、本発明に係る巻取装置及び巻取方法を図面を参照しつつ詳説する。 [Details of the embodiment of the present invention]
Hereinafter, a winding device and a winding method according to the present invention will be described in detail with reference to the drawings.
［第一実施形態］
＜巻取装置＞
　図１の巻取装置１は、円筒状の胴部１１ａ及びその両側に鍔部１１ｂを有するボビン１１を軸方向に往復移動させるボビン駆動機構１２を備え、ボビン１１に線材Ｘを多層整列巻きする巻取装置である。当該巻取装置１は、ボビン駆動機構１２及びボビン１１を回転させるボビン回転機構１３を有するトラバーサ２と、ボビン１１を胴部１１ａの接線方向から撮影するカメラ３と、カメラ３が撮影した画像に基づいてボビン１１の往復移動のタイミングを設定する制御部４とを備える。 [First embodiment]
<Winding device>
The winding device 1 shown in FIG. 1 includes a bobbin driving mechanism 12 that reciprocally moves a bobbin 11 having a cylindrical body 11a and flanges 11b on both sides thereof in the axial direction. It is a winding device. The winding device 1 includes a traverser 2 having a bobbin driving mechanism 12 and a bobbin rotating mechanism 13 that rotates the bobbin 11, a camera 3 that photographs the bobbin 11 from the tangential direction of the body 11 a, and an image captured by the camera 3. And a control unit 4 that sets the timing of the reciprocating movement of the bobbin 11.
　当該巻取装置１は、ボビン１１を胴部１１ａの接線方向から撮影するカメラ３を備えており、このカメラ３は既存層への線材Ｘの乗り上がり画像を撮影することができる。また、当該巻取装置１は、このカメラ３が撮影した画像に基づいてボビン１１の往復移動のタイミングを設定する制御部４を備えるので、線材Ｘの乗り上がりに基づいてボビン１１の往復移動を制御することができる。当該巻取装置１は、規定のプログラムによってボビン１１を往復移動させるものではなく、線材Ｘの乗り上がりに基づいて（つまり、実測データに基づいて）ボビン１１の往復移動を制御するものであるので、ボビン１１の鍔部１１ｂの内面に凹凸が形成されていた場合でもこの凹凸に基づく線乗り及び線落ちを抑制し易い。そのため、当該巻取装置１は、線材Ｘの線乗りや線落ちを容易かつ確実に抑制することができる。 The winding device 1 includes a camera 3 that photographs the bobbin 11 from the tangential direction of the body 11a, and the camera 3 can photograph an image of the wire X riding on an existing layer. Further, since the winding device 1 includes the control unit 4 that sets the timing of the reciprocating movement of the bobbin 11 based on the image captured by the camera 3, the rewinding movement of the bobbin 11 is performed based on the climbing of the wire X. Can be controlled. The winding device 1 does not reciprocate the bobbin 11 by a prescribed program, but controls the reciprocating movement of the bobbin 11 based on the climbing of the wire X (that is, based on measured data). Even when irregularities are formed on the inner surface of the flange portion 11b of the bobbin 11, it is easy to suppress line riding and line dropping based on the irregularities. Therefore, the winding device 1 can easily and reliably suppress the wire rod X and the wire drop of the wire X.
　線材Ｘは、アームガイドＹを介してボビン１１の胴部１１ａに巻き付けられる。線材Ｘは、平角線であっても丸線であってもよいが、平角線を用いることで当該巻取装置１の効果がより発揮される。線材Ｘの種類としては特に限定されるものではないが、例えば銅等の金属導体からなる単芯線に絶縁塗料を焼き付け塗布したエナメル線等の被覆電線が好適に用いられる。また、線材Ｘの厚さや幅は特に限定されるものではないが、当該巻取装置１は、例えば平均厚さが０．５ｍｍ以上５ｍｍ以下、平均幅が１ｍｍ以上１０ｍｍ以下のものを好適に巻き取ることができる。 The wire X is wound around the body 11a of the bobbin 11 via the arm guide Y. The wire X may be a flat wire or a round wire, but the effect of the winding device 1 is more exhibited by using a flat wire. Although it does not specifically limit as a kind of wire X, For example, the covered electric wire, such as an enamel wire which baked and applied the insulating paint to the single core wire which consists of metal conductors, such as copper, is used suitably. Moreover, although the thickness and width of the wire X are not particularly limited, the winding device 1 preferably has a mean thickness of 0.5 mm to 5 mm and a mean width of 1 mm to 10 mm, for example. Can be taken.
（トラバーサ）
　トラバーサ２は、上述のボビン駆動機構１２及びボビン回転機構１３と、台座となる支持台１４とを有する。 (Traversa)
The traverser 2 includes the bobbin driving mechanism 12 and the bobbin rotating mechanism 13 described above, and a support base 14 serving as a pedestal.
　支持台１４は、ボビン駆動機構１２及びボビン回転機構１３が載置される基台であり、トラバーサ２の最下部に位置する。 The support base 14 is a base on which the bobbin driving mechanism 12 and the bobbin rotation mechanism 13 are placed, and is located at the lowest part of the traverser 2.
　ボビン駆動機構１２は、スクリューシャフト１２ａ、移動台１２ｂ及び位置制御モータ１２ｃを有する。 The bobbin driving mechanism 12 includes a screw shaft 12a, a moving table 12b, and a position control motor 12c.
　スクリューシャフト１２ａは、螺旋状の溝（ネジ溝）が刻まれたシャフトであり、一端が移動台１２ｂに螺合され、他端が位置制御モータ１２ｃの軸に接合されている。 The screw shaft 12a is a shaft in which a spiral groove (screw groove) is engraved, and one end is screwed to the moving base 12b and the other end is joined to the shaft of the position control motor 12c.
　移動台１２ｂは、上記スクリューシャフト１２ａと螺合するネジ穴を有し、スクリューシャフト１２ａの回転に応じてスクリューシャフト１２ａの軸方向に移動するように支持台１４上に配設されている。 The moving table 12b has a screw hole to be screwed with the screw shaft 12a, and is arranged on the support table 14 so as to move in the axial direction of the screw shaft 12a according to the rotation of the screw shaft 12a.
　位置制御モータ１２ｃは、スクリューシャフト１２ａを回転させるモータである。位置制御モータ１２ｃは、正逆回転可能である。この位置制御モータ１２ｃによりスクリューシャフト１２ａを回転させることで、移動台１２ｂがスクリューシャフト１２ａの軸方向に移動する。また、位置制御モータ１２ｃの回転方向を変えることで移動台１２ｂを往復移動させることができる。 The position control motor 12c is a motor that rotates the screw shaft 12a. The position control motor 12c can rotate forward and backward. By rotating the screw shaft 12a by the position control motor 12c, the moving base 12b moves in the axial direction of the screw shaft 12a. Further, the movable table 12b can be reciprocated by changing the rotation direction of the position control motor 12c.
　ボビン回転機構１３は、ボビン取り付け用のスピンドル１３ａ、このスピンドル１３ａを回転自在に支持する軸受材１３ｂ、及びギア１３ｄを介して上記スピンドル１３ａを回転させる回転用モータ１３ｃを有する。 The bobbin rotating mechanism 13 includes a bobbin mounting spindle 13a, a bearing member 13b that rotatably supports the spindle 13a, and a rotating motor 13c that rotates the spindle 13a via a gear 13d.
　スピンドル１３ａは、回転用モータ１３ｃの回転動力をボビン１１に伝える円柱状部材である。スピンドル１３ａは、ボビン１１の胴部内部に軸方向が一致するよう装着可能に構成されている。スピンドル１３ａは、スクリューシャフト１２ａと軸方向が一致するよう配設されている。 The spindle 13a is a columnar member that transmits the rotational power of the rotation motor 13c to the bobbin 11. The spindle 13 a is configured to be mountable so that the axial direction coincides with the inside of the body portion of the bobbin 11. The spindle 13a is arranged so that the axial direction thereof coincides with the screw shaft 12a.
　軸受材１３ｂは、スピンドル１３ａを回転自在に支持する軸受である。ボビン回転機構１３は、スピンドル１３ａが軸受材１３ｂに支持された状態で、ボビン１１が装着されたスピンドル１３ａを回転させることでボビン１１を回転させる。 The bearing material 13b is a bearing that rotatably supports the spindle 13a. The bobbin rotating mechanism 13 rotates the bobbin 11 by rotating the spindle 13a on which the bobbin 11 is mounted while the spindle 13a is supported by the bearing material 13b.
　回転用モータ１３ｃは、移動台１２ｂ上に配設され、ギア１３ｄを介してスピンドル１３ａと接続されている。回転用モータ１３ｃがスピンドル１３ａを回転させることで、線材Ｘがボビン１１に巻き取られる。回転用モータ１３ｃは回転速度を可変に構成されてもよく、回転速度を不変に構成されてもよい。 The rotation motor 13c is disposed on the moving table 12b and is connected to the spindle 13a via a gear 13d. The wire X is wound around the bobbin 11 by the rotation motor 13c rotating the spindle 13a. The rotation motor 13c may be configured to have a variable rotation speed, or may be configured to have a constant rotation speed.
　トラバーサ２は以上のように構成されているので、当該巻取装置１は、位置制御モータ１２ｃを用いて移動台１２ｂを往復移動させることで、ボビン駆動機構１２によりボビン１１を往復移動させることができる。また、当該巻取装置１は、ボビン１１をスピンドル１３ａに装着し、回転用モータ１３ｃを用いてスピンドル１３ａを回転させることで、ボビン回転機構１３によりボビン１１を回転させることができる。そのため、当該巻取装置１は、位置を固定したアームガイドＹからボビン１１の軸方向に対して垂直方向に供給される線材Ｘをボビン１１の回転及び軸方向の往復移動によりボビン１１に多層に巻き取ることができる。このようなトラバーサ２としては、公知のものを利用できる。 Since the traverser 2 is configured as described above, the winding device 1 can reciprocate the bobbin 11 by the bobbin driving mechanism 12 by reciprocating the moving table 12b using the position control motor 12c. it can. Further, the winding device 1 can rotate the bobbin 11 by the bobbin rotating mechanism 13 by mounting the bobbin 11 on the spindle 13a and rotating the spindle 13a using the rotation motor 13c. Therefore, the winding device 1 is configured so that the wire rod X supplied in a direction perpendicular to the axial direction of the bobbin 11 from the arm guide Y whose position is fixed is multilayered on the bobbin 11 by rotating the bobbin 11 and reciprocating in the axial direction. Can be wound up. As such a traverser 2, a known one can be used.
（カメラ）
　カメラ３は、ボビン１１を胴部１１ａの接線方向から撮影できるよう配設されており、本実施形態では、図２に示すように、ボビン１１の軸方向と垂直方向から胴部１１ａに巻き付けられた線材Ｘを撮影可能に配設されている。また、カメラ３は、鍔部１１ｂの内面（対向面）近傍位置における線材Ｘを連続的に撮影できるように構成されており、これにより線材Ｘの既存層への乗り上がりを撮影可能に構成されている。なお、当該巻取装置１は、後述のように、カメラ３によって線材Ｘの乗り上がり画像を撮影した後、カメラ３が撮影したこの画像を基にボビン１１の往復移動を制御する。そのため、当該巻取装置１にあっては、カメラ３が線材Ｘの乗り上がりを早期に撮影できる方がボビン１１の往復移動を制御し易い。このような点から、カメラ３は、アームガイドＹから供給された線材Ｘがボビン１１に重積される点から２１０°巻かれる前の線材Ｘを撮影できるよう配設されることが好ましい。カメラ３としては、例えばＣＣＤ（Ｃｈａｒｇｅ　Ｃｏｕｐｌｅｄ　Ｄｅｖｉｃｅｓ）カメラ、ＣＭＯＳ（Ｃｏｍｐｌｅｍｅｎｔａｒｙ　Ｍｅｔａｌ　Ｏｘｉｄｅ　Ｓｅｍｉｃｏｎｄｕｃｔｏｒ）カメラ等を用いることができる。 (camera)
The camera 3 is arranged so that the bobbin 11 can be photographed from the tangential direction of the body part 11a. In this embodiment, the camera 3 is wound around the body part 11a from the direction perpendicular to the axial direction of the bobbin 11 as shown in FIG. The wire X is arranged so that it can be photographed. In addition, the camera 3 is configured to be able to continuously photograph the wire X in the vicinity of the inner surface (opposing surface) of the flange portion 11b, and is configured to be able to photograph the climbing of the wire X onto the existing layer. ing. In addition, the winding device 1 controls the reciprocation of the bobbin 11 based on this image captured by the camera 3 after capturing the climbing image of the wire X with the camera 3 as described later. Therefore, in the winding device 1, it is easier to control the reciprocating movement of the bobbin 11 if the camera 3 can photograph the climbing of the wire X at an early stage. From such a point, it is preferable that the camera 3 is arranged so as to be able to photograph the wire X before being wound by 210 ° from the point where the wire X supplied from the arm guide Y is stacked on the bobbin 11. As the camera 3, for example, a CCD (Charge Coupled Devices) camera, a CMOS (Complementary Metal Oxide Semiconductor) camera, or the like can be used.
（制御部）
　制御部４は、例えばパーソナルコンピューターやプログラマブルコントローラー等により構成することができる。制御部４は、上述のようにカメラ３が撮影した画像に基づいてボビン１１の往復移動のタイミングを設定する。具体的には、制御部４は、カメラ３が線材Ｘの既存層への乗り上がり画像を撮影すると、この画像に基づいて線材Ｘの乗り上がり位置を基準としてボビン１１を反転移動させるようボビン駆動機構１２を制御する。 (Control part)
The control part 4 can be comprised by a personal computer, a programmable controller, etc., for example. The control unit 4 sets the reciprocating timing of the bobbin 11 based on the image captured by the camera 3 as described above. Specifically, when the camera 3 captures an image of the wire X traveling on the existing layer, the control unit 4 drives the bobbin so as to reversely move the bobbin 11 with reference to the position where the wire X climbs based on the image. The mechanism 12 is controlled.
　図２～図４を参照して、当該巻取装置１におけるボビン１１の往復移動の制御機構について説明する。まず、当該巻取装置１は、ボビン駆動機構１２及びボビン回転機構１３によりボビン１１を周方向であるＺ方向に回転及び軸方向に移動させつつアームガイドＹから供給される線材Ｘを胴部１１ａに巻き取っていく。そして、制御部４は、線材Ｘが鍔部１１ｂの内面近傍に至るとボビン１１の軸方向の移動を停止させる。ボビン１１の軸方向の移動を停止させる手順としては、特に限定されるものではなく、例えば線材Ｘと鍔部１１ｂとの軸方向間隔を測定し、この間隔が一定以下となった場合にボビン１１の軸方向の移動を停止させればよい。 A control mechanism for the reciprocating movement of the bobbin 11 in the winding device 1 will be described with reference to FIGS. First, the winding device 1 uses the bobbin driving mechanism 12 and the bobbin rotating mechanism 13 to rotate the bobbin 11 in the Z direction, which is the circumferential direction, and move the wire X supplied from the arm guide Y in the axial direction while the body 11a. I will wind it up. And the control part 4 stops the movement of the axial direction of the bobbin 11, if the wire X reaches the inner surface vicinity of the collar part 11b. The procedure for stopping the movement of the bobbin 11 in the axial direction is not particularly limited. For example, the axial distance between the wire X and the flange portion 11b is measured, and the bobbin 11 when the distance is less than a certain value. The movement in the axial direction may be stopped.
　次に、ボビン１１の軸方向の移動が停止されると、線材Ｘは、ボビン１１の胴部１１ａにおける鍔部１１ｂの内面近傍の部分に巻かれていき、この部分において３６０°巻かれた際に、図２に示すように乗り上がり位置Ｘ１において既存層に乗り上がる。 Next, when the movement of the bobbin 11 in the axial direction is stopped, the wire X is wound around a portion of the body portion 11a of the bobbin 11 in the vicinity of the inner surface of the flange portion 11b, and when this portion is wound 360 ° In addition, as shown in FIG.
　さらに、線材Ｘは、乗り上がり位置Ｘ１において既存層に乗り上げた後も、ボビン１１の胴部１１ａにおける鍔部１１ｂの内面近傍の部分に巻かれていく。そして、図３に示すように、既存層に乗り上げ後、所定の角度巻き取られた時点で、この乗り上がり部分はカメラ３の撮影領域に至る。一方、カメラ３は、胴部１１ａの接線方向からボビン１１を連続的に撮影しているため、図４に示す乗り上がり画像がカメラ３によって撮影される。カメラ３によって乗り上がり画像が撮影されると、制御部４は、画像処理によって線材Ｘの乗り上がりを認識し、線材Ｘの既存層への乗り上がり位置Ｘ１を基準とする（つまり、乗り上がり位置Ｘ１を０°とする）ボビン１１の回転角度に基づいてボビン１１を反転移動制御する。なお、カメラ３が上記画像処理を行い、制御部４がこの画像処理データを受信してボビン１１を反転移動制御してもよい。 Furthermore, the wire X is wound around a portion of the body 11a of the bobbin 11 in the vicinity of the inner surface of the flange 11b even after riding on the existing layer at the climbing position X1. Then, as shown in FIG. 3, after riding on the existing layer, the climbed portion reaches the photographing region of the camera 3 when it is wound up at a predetermined angle. On the other hand, since the camera 3 continuously captures the bobbin 11 from the tangential direction of the trunk portion 11a, the climbing image shown in FIG. When a climbing image is captured by the camera 3, the control unit 4 recognizes the climbing of the wire X by image processing and uses the climbing position X1 of the wire X on the existing layer as a reference (that is, the climbing position). Based on the rotation angle of the bobbin 11, the reverse movement of the bobbin 11 is controlled. Note that the camera 3 may perform the above-described image processing, and the control unit 4 may receive the image processing data and perform the reverse movement control of the bobbin 11.
　線材Ｘの既存層への乗り上がり位置Ｘ１を基準とするボビン１１が反転移動を開始する角度の下限としては１５０°、上限としては３００°の範囲にあることが好ましい。上記角度が上記下限に満たないと、ボビン１１の反転移動が早くなり過ぎて、層上がりした位置における線材Ｘの層厚が不足して、巻き取り後に線材Ｘをスムーズに繰り出し難くなるおそれがある。逆に、上記角度が上記上限を超えると、層上がりした位置における線材Ｘの層厚が大きくなり、巻き取り後に線材Ｘをスムーズに繰り出し難くなるおそれがある。
なお、線材Ｘがボビン１１に重積された点からカメラ３によって撮影されるまでのボビン１１の回転角度は予め制御部４に記憶されている。ボビン１１の反転移動は、この重積点を基準とするボビン１１の回転角度が所定の値となった時にボビン１１を反転移動するよう制御部４がボビン駆動機構１２を制御することで行われる。 It is preferable that the lower limit of the angle at which the bobbin 11 starts the reversal movement with respect to the position X1 of the wire X on the existing layer is 150 ° and the upper limit is 300 °. If the angle is less than the lower limit, the reversal movement of the bobbin 11 becomes too fast, the layer thickness of the wire X at the position where the layer is raised is insufficient, and it is difficult to smoothly feed the wire X after winding. . On the other hand, if the angle exceeds the upper limit, the layer thickness of the wire X at the position where the layer is raised increases, and it may be difficult to smoothly feed the wire X after winding.
Note that the rotation angle of the bobbin 11 from the point where the wire X is stacked on the bobbin 11 until the image is taken by the camera 3 is stored in the control unit 4 in advance. The reverse movement of the bobbin 11 is performed by the control unit 4 controlling the bobbin driving mechanism 12 so as to reversely move the bobbin 11 when the rotation angle of the bobbin 11 with respect to this stacking point becomes a predetermined value. .
＜巻取方法＞
　次に、本発明に係る巻取方法について説明する。当該巻取方法は、円筒状の胴部及びその両側の鍔部を有するボビンを軸方向に往復移動させ、ボビンに線材を多層整列巻きする巻取方法であって、図１の当該巻取装置１を用いて行うことができる。当該巻取方法は、ボビン１１を胴部１１ａの接線方向から撮影する撮影工程と、上記撮影工程で撮影した画像に基づいてボビン１１の往復移動のタイミングを設定する制御工程とを備える。 <Winding method>
Next, the winding method according to the present invention will be described.

The control process is performed by the control unit 4. In the control step, the bobbin driving mechanism 12 is controlled so as to reversely move the bobbin 11 based on the riding position X1 based on the running image of the wire X taken in the photographing step onto the existing layer. In addition, it is preferable that the said control process stops the movement of the bobbin 11 in the axial direction when the wire X reaches the vicinity of the inner surface of the flange portion 11b before the bobbin 11 is reversed.
　当該巻取方法は、ボビン１１を胴部１１ａの接線方向から撮影する撮影工程を備えるので、撮影工程によって既存層への線材Ｘの乗り上がり画像を撮影することができる。また、当該巻取方法は、撮影工程で撮影した画像に基づいてボビン１１の往復移動のタイミングを設定する制御工程を備えるので、線材Ｘの乗り上がりに基づいてボビンの往復移動を制御することができる。そのため、当該巻取方法は、既述のように線材Ｘの線乗りや線落ちを容易かつ確実に抑制することができる。 Since the winding method includes a photographing step of photographing the bobbin 11 from the tangential direction of the trunk portion 11a, it is possible to photograph a running image of the wire X on the existing layer by the photographing step. Further, since the winding method includes a control step of setting the timing of the reciprocating movement of the bobbin 11 based on the image photographed in the photographing step, the reciprocating movement of the bobbin can be controlled based on the climbing of the wire X. it can. Therefore, the winding method can easily and surely suppress the wire riding and wire dropping of the wire X as described above.

（制御部）
　制御部２４は、例えばパーソナルコンピューターやプログラマブルコントローラー等により構成することができる。制御部２４は、図１の巻取装置１の制御部４と同様、カメラ３が線材Ｘの既存層への乗り上がり画像を撮影すると、この画像に基づいて線材Ｘの乗り上がり位置を基準としてボビン１１を反転移動させるようボビン駆動機構１２を制御する。また、制御部２４は、一対の変位センサー２３が測定した間隔に基づいてボビン１１の往復移動を停止可能に構成されている。具体的には、制御部２４は、一対の変位センサー２３によって測定された変位センサー２３と鍔部１１ｂの内面との間隔から、ボビン１１に巻き取られる線材Ｘの外側の側面（鍔部１１ｂ側の側面）と鍔部１１ｂの内面との間隔を算出し、この間隔が一定値以下（例えば線材Ｘの幅よりも小さい値）となる時点でボビン１１の移動を停止可能に構成されている。 (Control part)
The control part 24 can be comprised by a personal computer, a programmable controller, etc., for example. As with the control unit 4 of the winding device 1 shown in FIG. 1, when the camera 3 takes an image of the wire X riding on the existing layer, the control unit 24 uses the climbing position of the wire X as a reference based on this image. The bobbin driving mechanism 12 is controlled to reversely move the bobbin 11. The control unit 24 is configured to be able to stop the reciprocation of the bobbin 11 based on the interval measured by the pair of displacement sensors 23. Specifically, the control unit 24 determines the outer side surface of the wire X wound around the bobbin 11 (the side of the flange 11b) from the distance between the displacement sensor 23 measured by the pair of displacement sensors 23 and the inner surface of the flange 11b. ) And the inner surface of the flange portion 11b are calculated, and the movement of the bobbin 11 can be stopped when the interval is equal to or smaller than a certain value (for example, a value smaller than the width of the wire X).
　図６，７を参照して、当該巻取装置２１における線材Ｘ及び鍔部１１ｂの軸方向間隔の測定機構について説明する。まず、当該巻取装置２１は、図６に示すように、線材Ｘがボビン１１の一方の鍔部１１ｂ側に巻き取られる際に、線材整列機構２２の一対のローラーユニット３１のうち小径ローラー３７が一方の鍔部１１ｂ側に位置する一方のローラーユニット３１をこの巻き取られる線材Ｘの外周に沿うように配置する。そして、この一方のローラーユニット３１のアーム部３５に取り付けられた変位センサー２３が、この変位センサー２３と鍔部１１ｂの内面との間隔Ｄを連続的に測定することで、線材Ｘに対する鍔部１１ｂの軸方向間隔を測定する。そして、図７に示すように、変位センサー２３と鍔部１１ｂの内面との間隔Ｄが一定の値以下になると、制御部２４は線材Ｘが鍔部１１ｂ近傍に至ったものと判断してボビン１１の移動を停止する。なお、当該巻取装置２１にあっては、上記間隔Ｄを基に線材Ｘの外側の側面（鍔部１１ｂ側の側面）と鍔部１１ｂの内面との間隔が測定できればよい。当該巻取装置２１は、変位センサー２３と線材Ｘの外側の側面との軸方向間隔を一定に保ちつつ、上記間隔Ｄを測定し、これらの値から線材Ｘの外側の側面と鍔部１１ｂの内面との正確な間隔を算出してもよい。 With reference to FIGS. 6 and 7, the measuring mechanism of the axial distance between the wire X and the flange 11b in the winding device 21 will be described. First, as shown in FIG. 6, the winding device 21 has a small-diameter roller 37 of the pair of roller units 31 of the wire rod alignment mechanism 22 when the wire rod X is wound on the one flange portion 11 b side of the bobbin 11. Is arranged so as to be along the outer periphery of the wire X to be wound up. And the displacement sensor 23 attached to the arm part 35 of this one roller unit 31 measures the space | interval D of this displacement sensor 23 and the inner surface of the collar part 11b continuously, The collar part 11b with respect to the wire X Measure the axial spacing of. Then, as shown in FIG. 7, when the distance D between the displacement sensor 23 and the inner surface of the flange portion 11b is equal to or less than a certain value, the control unit 24 determines that the wire X has reached the vicinity of the flange portion 11b. 11 stops moving. In addition, in the said winding apparatus 21, the space | interval of the outer side surface (side surface by the side of the collar part 11b) of the wire X and the inner surface of the collar part 11b should just be measured based on the said space | interval D. The winding device 21 measures the distance D while keeping the axial distance between the displacement sensor 23 and the outer side surface of the wire X constant, and from these values, the outer side surface of the wire X and the flange portion 11b. You may calculate the exact space | interval with an inner surface.
　なお、この一方のローラーユニット３１は、ボビン１１が反転移動した際には、ボビン１１に巻き取られる線材Ｘの外面に小径ローラー３７の周面を当接させ、かつ大径ローラー３６の側面（小径ローラー３７側の面）を線材Ｘの側面に当接させてボビン１１の鍔部１１ｂ側に線材Ｘを押圧し、線材Ｘ間の隙間を制御する。 In addition, when the bobbin 11 reversely moves, the one roller unit 31 causes the outer surface of the wire X wound around the bobbin 11 to abut the peripheral surface of the small diameter roller 37 and the side surface of the large diameter roller 36 ( The surface of the small-diameter roller 37 side) is brought into contact with the side surface of the wire rod X, the wire rod X is pressed against the flange portion 11b side of the bobbin 11, and the gap between the wire rods X is controlled.
　当該巻取装置２１は、線材Ｘに対する鍔部１１ｂの軸方向間隔を測定する変位センサー２３を備えることによって、線材Ｘ及び鍔部１１ｂの軸方向間隔に基づいてボビン１１の移動を停止することができる。当該巻取装置２１は、規定のプログラムによってボビンを移動を停止させるものではなく、実測データに基づいてボビン１１の移動を停止するものであるので、鍔部１１ｂの内面に凹凸が形成されていた場合でもこの凹凸に基づく線乗り及び線落ちを抑制し易い。そのため、当該巻取装置２１は、往復移動をより的確に制御することができる。また、当該巻取装置２１は、変位センサー２３が線材整列機構２２に取り付けられていることによって、線材Ｘ及び鍔部１１ｂの軸方向間隔を容易かつ確実に測定することができる。 The winding device 21 includes a displacement sensor 23 that measures the axial interval of the flange portion 11b with respect to the wire X, thereby stopping the movement of the bobbin 11 based on the axial interval of the wire X and the flange portion 11b. it can. Since the winding device 21 does not stop the movement of the bobbin according to a prescribed program, but stops the movement of the bobbin 11 based on the actual measurement data, the unevenness is formed on the inner surface of the flange portion 11b. Even in this case, it is easy to suppress line riding and line dropping based on the unevenness. Therefore, the winding device 21 can more accurately control the reciprocating movement. Further, the winding device 21 can easily and surely measure the axial distance between the wire X and the flange portion 11b because the displacement sensor 23 is attached to the wire alignment mechanism 22.
　なお、線材Ｘがボビン１１の他方側に巻き取られる際は、線材整列機構２２の一対のローラーユニット３１のうち小径ローラー３７が他方の鍔部１１ｂ側に位置する他方のローラーユニット３１をこの巻き取られる線材Ｘの外周に沿うように配置し、この他方のローラーユニット３１のアーム部３５に取り付けられた変位センサー２３によって線材Ｘに対する鍔部１１ｂの軸方向間隔を測定すればよい。 When the wire X is wound around the other side of the bobbin 11, the other roller unit 31 in which the small-diameter roller 37 of the pair of roller units 31 of the wire alignment mechanism 22 is positioned on the other flange 11b side is wound. What is necessary is just to measure the axial direction space | interval of the collar part 11b with respect to the wire X with the displacement sensor 23 arrange | positioned along the outer periphery of the taken wire X, and was attached to the arm part 35 of this other roller unit 31.
＜巻取方法＞
　次に、図５の当該巻取装置２１を用いた巻取方法について説明する。当該巻取方法は、カメラ３が撮影した画像及び一対の変位センサー２３が測定した間隔に基づいてボビン１１の往復移動のタイミングを設定する制御工程と、ボビン１１を胴部１１ａの接線方向から撮影する撮影工程とを備える。また、上記制御工程は、ボビン１１の移動を停止する移動停止工程と、ボビン１１を反転移動させる反転移動工程とを有する。当該巻取方法は、上記移動停止工程、撮影工程、反転移動工程の順で行われる。上記撮影工程は、上述の第一実施形態における撮影工程と同様であり、上記反転移動工程は、上述の第一実施形態の制御工程と同様であるため説明を省略する。 <Winding method>
Next, a winding method using the winding device 21 of FIG. 5 will be described. The winding method includes a control step of setting the reciprocating timing of the bobbin 11 based on the image taken by the camera 3 and the interval measured by the pair of displacement sensors 23, and the bobbin 11 taken from the tangential direction of the body 11a. And a photographing process. The control process includes a movement stopping process for stopping the movement of the bobbin 11 and a reversing movement process for reversing the bobbin 11. The winding method is performed in the order of the movement stop step, the photographing step, and the reverse movement step. The imaging process is the same as the imaging process in the first embodiment described above, and the reversal movement process is the same as the control process in the first embodiment described above, and thus the description thereof is omitted.
（移動停止工程）
　上記移動停止工程は、一対の変位センサー２３及び制御部２４によって行われる。上記移動停止工程では、まず一対の変位センサー２３が、この一対の変位センサー２３と鍔部１１ｂの内面との間隔を連続的に測定することで、線材Ｘに対する鍔部１１ｂの軸方向間隔を測定する。さらに、上記移動停止工程では、制御部２４が、一対の変位センサー２３と鍔部１１ｂの内面との間隔が一定の値以下になると、線材Ｘが鍔部１１ｂ近傍に至ったものと判断してボビン１１の往復移動を停止する。 (Moving stop process)
The movement stop process is performed by the pair of displacement sensors 23 and the control unit 24. In the movement stop process, first, the pair of displacement sensors 23 continuously measure the distance between the pair of displacement sensors 23 and the inner surface of the flange 11b, thereby measuring the axial distance of the flange 11b with respect to the wire X. To do. Further, in the movement stop step, the control unit 24 determines that the wire X has reached the vicinity of the flange 11b when the distance between the pair of displacement sensors 23 and the inner surface of the flange 11b is equal to or less than a certain value. The reciprocation of the bobbin 11 is stopped.
　当該巻取方法は、上記移動停止工程を備えるので、線材Ｘが鍔部１１ｂ近傍に至った位置でボビン１１の軸方向の移動を容易かつ確実に停止することができる。そのため、当該巻取方法は、線材Ｘの線乗りや線落ち（特に、鍔部１１ｂの内面の凹凸に起因する線材Ｘの線乗りや線落ち）をより的確に抑制することができる。 Since the winding method includes the movement stopping step, the movement of the bobbin 11 in the axial direction can be easily and reliably stopped at the position where the wire X reaches the vicinity of the flange portion 11b. Therefore, the said winding method can suppress more correctly the wire riding and wire fall of the wire X (especially the wire riding and wire fall of the wire X resulting from the unevenness | corrugation of the inner surface of the collar part 11b).
