特開２００６−１３１５０号公報JP 2006-13150 A

上記従来技術は、１本のコイル（ワイヤ）をコアに巻回してコイル部品を製造するものであるが、コイル部品としては、１対のワイヤをコアに巻回するものもある。このようなコイル部品において、１対のワイヤを整列状態でよじれないように端子金具に巻き付けるという工程を自動的に行うことは困難である。１対のワイヤをコアに巻回した後に、各ワイヤの両端部を端子金具に巻き付けるという方法であれば、１対のワイヤを整列状態で端子金具に巻き付けることは可能であるが、その場合には各ワイヤの両端部を別々の駆動機構で動かす必要があり、装置構成が複雑になってしまう。   In the above-described prior art, a coil component is manufactured by winding a single coil (wire) around a core. However, there is a coil component in which a pair of wires are wound around a core. In such a coil component, it is difficult to automatically perform a process of winding a pair of wires around a terminal fitting so as not to be twisted in an aligned state. If a method of winding a pair of wires around a core and then winding both ends of each wire around a terminal fitting, it is possible to wind a pair of wires around the terminal fitting in an aligned state. However, it is necessary to move both ends of each wire by a separate drive mechanism, which complicates the apparatus configuration.

本発明の目的は、装置構成を複雑化すること無く、１対のワイヤを整列状態で端子金具に巻き付けることができるコイル部品の製造装置を提供することである。   An object of the present invention is to provide a coil component manufacturing apparatus capable of winding a pair of wires around a terminal fitting in an aligned state without complicating the apparatus configuration.

本発明は、１対のワイヤがコアに巻回されると共に各ワイヤの両端部が１対の端子金具に継線されてなるコイル部品の製造装置であって、コア及び１対の端子金具を保持する保持部材と、保持部材を回転駆動させる第１駆動手段と、１対のワイヤを整列状態で供給するワイヤ供給部材と、ワイヤ供給部材を回転駆動させる第２駆動手段と、ワイヤ供給部材により供給される各ワイヤを保持する回転自在なワイヤホルダと、ワイヤ供給部材とワイヤホルダとを一体で３軸方向に移動させる第３駆動手段とを備えることを特徴とするものである。   The present invention is an apparatus for manufacturing a coil component in which a pair of wires are wound around a core and both ends of each wire are connected to a pair of terminal fittings. A holding member for holding; a first driving means for rotating the holding member; a wire supplying member for supplying a pair of wires in an aligned state; a second driving means for rotating the wire supplying member; and a wire supplying member. A rotatable wire holder for holding each supplied wire, and a third driving means for integrally moving the wire supply member and the wire holder in three axial directions.

このようなコイル部品の製造装置において、保持部材に保持されたコア及び１対の端子金具に１対のワイヤを装着する場合は、まず第３駆動手段によりワイヤ供給部材及びワイヤホルダを一体で動かして、各ワイヤをコアに引っ掛けた状態で１対の端子金具のいずれか一方に各ワイヤを巻き付け、その後で各ワイヤをカットする。そして、第１駆動手段により保持部材を回転駆動させて、各ワイヤをコアに巻き付ける。そして、第３駆動手段によりワイヤ供給部材及びワイヤホルダを一体で動かして、１対の端子金具の他方に各ワイヤを巻き付け、その後で各ワイヤをカットする。   In such a coil component manufacturing apparatus, when mounting a pair of wires to a core and a pair of terminal fittings held by a holding member, first, the wire supply member and the wire holder are moved together by the third driving means. Each wire is wound around one of a pair of terminal fittings with each wire hooked on the core, and then each wire is cut. Then, the holding member is rotationally driven by the first driving means, and each wire is wound around the core. And a wire supply member and a wire holder are moved integrally by a 3rd drive means, each wire is wound around the other of a pair of terminal metal fittings, and each wire is cut after that.

このとき、ワイヤホルダは回転自在であるので、ワイヤホルダが一方の端子金具に対して公転するようにワイヤ供給部材及びワイヤホルダを一体で動かして、各ワイヤを一方の端子金具に巻き付けると、ワイヤホルダは各ワイヤのテンションのかかる方向に回転（自転）するようになる。このため、ワイヤ供給部材により整列状態で供給された各ワイヤがよじれて重なることが無く、各ワイヤは整列状態を保ったまま一方の端子金具に巻き付けられることとなる。また、ワイヤ供給部材が他方の端子金具に対して公転するようにワイヤ供給部材を動かして、各ワイヤを他方の端子金具に巻き付けると共に、第２駆動手段によってワイヤ供給部材を各ワイヤのテンションのかかる方向に回転（自転）させることで、上記と同様に各ワイヤは整列状態を保ったまま他方の端子金具に巻き付けられるようになる。このように各ワイヤの両端部を別々の駆動機構で動かさなくても、各ワイヤを整列状態で１対の端子金具に巻き付けることができる。   At this time, since the wire holder is rotatable, when the wire supply member and the wire holder are moved together so that the wire holder revolves with respect to one terminal fitting, and each wire is wound around one terminal fitting, the wire holder Rotate (rotate) in the direction of the tension. For this reason, the wires supplied in an aligned state by the wire supply member are not twisted and overlapped, and each wire is wound around one terminal fitting while maintaining the aligned state. Further, the wire supply member is moved so that the wire supply member revolves with respect to the other terminal fitting, and each wire is wound around the other terminal fitting, and the wire driving member is tensioned by the second driving means. By rotating (spinning) in the direction, each wire is wound around the other terminal fitting while maintaining the aligned state as described above. Thus, each wire can be wound around a pair of terminal fittings in an aligned state without moving both ends of each wire with separate drive mechanisms.

好ましくは、１対の端子金具のいずれか一方に各ワイヤを継線する際に、各ワイヤを一方の端子金具に沿うようにガイドする第１ワイヤガイド部と、１対の端子金具の他方に各ワイヤを継線する際に、各ワイヤを他方の端子金具に沿うようにガイドする第２ワイヤガイド部とを更に備える。この場合には、各ワイヤを１対の端子金具に巻き付ける際に、各ワイヤの両端部を端子金具に沿って継線することができる。   Preferably, when connecting each wire to one of the pair of terminal fittings, the first wire guide portion for guiding each wire along the one terminal fitting and the other of the pair of terminal fittings A second wire guide portion for guiding each wire along the other terminal fitting when connecting the wires is further provided. In this case, when winding each wire around a pair of terminal fittings, both ends of each wire can be connected along the terminal fitting.

また、好ましくは、ワイヤ供給部材のワイヤ引き出し部の高さ位置がワイヤホルダのワイヤ保持部の高さ位置よりも高い。この場合には、ワイヤ供給部材のワイヤ引き出し部から引き出された各ワイヤをワイヤホルダのワイヤ保持部に保持したときに、各ワイヤの引き出し角度が鈍角になるため、各ワイヤに過剰なテンションがかかることが防止される。また、ワイヤホルダにより各ワイヤを保持した状態で、ワイヤ供給部材を回転させる際に、各ワイヤがワイヤ供給部材に絡まることが防止される。   Preferably, the height position of the wire drawing portion of the wire supply member is higher than the height position of the wire holding portion of the wire holder. In this case, when each wire pulled out from the wire pulling portion of the wire supply member is held in the wire holding portion of the wire holder, the pulling angle of each wire becomes an obtuse angle, so that excessive tension is applied to each wire. Is prevented. Further, when the wire supply member is rotated while the wires are held by the wire holder, the wires are prevented from being tangled with the wire supply member.

本発明によれば、装置構成を複雑化すること無く、１対のワイヤを整列状態で端子金具に巻き付けることができる。これにより、端子金具と各ワイヤとを半田で良好に継線することが可能となる。   According to the present invention, a pair of wires can be wound around a terminal fitting in an aligned state without complicating the device configuration. As a result, the terminal fitting and each wire can be satisfactorily connected with the solder.

図１は、本発明に係わるコイル部品の製造装置の一実施形態を示す正面図であり、図２は、図１に示した製造装置の平面図であり、図３は、図１に示した製造装置の側面図である。各図において、本実施形態の製造装置１は、図４に示すようなコイル部品２を製造する装置である。   FIG. 1 is a front view showing an embodiment of a coil component manufacturing apparatus according to the present invention, FIG. 2 is a plan view of the manufacturing apparatus shown in FIG. 1, and FIG. 3 is shown in FIG. It is a side view of a manufacturing apparatus. In each figure, the manufacturing apparatus 1 of this embodiment is an apparatus which manufactures the coil components 2 as shown in FIG.

コイル部品２は、ベースプレート３と、このベースプレート３上に載置されたドラムコア４と、このドラムコア４の巻芯部に巻回された１対のワイヤ（巻線）５と、ドラムコア４を挟むようにベースプレート３の両側に設けられた１対の端子金具６Ａ，６Ｂとを備えている。１対のワイヤ５の両端部は、端子金具６Ａ，６Ｂに半田で接合されている。なお、ここでいう１対のワイヤ５とは、１対の平行な導体線を絶縁材で一体に被覆してなるペア線ではなく、単線のワイヤを単に１対に並べたものである。   The coil component 2 sandwiches the drum core 4 with a base plate 3, a drum core 4 placed on the base plate 3, a pair of wires (windings) 5 wound around the core of the drum core 4, and the coil core 4. Are provided with a pair of terminal fittings 6A and 6B provided on both sides of the base plate 3. Both ends of the pair of wires 5 are joined to the terminal fittings 6A and 6B with solder. Here, the pair of wires 5 is not a pair of wires formed by integrally covering a pair of parallel conductor wires with an insulating material, but simply a single wire arranged in a pair.

図１〜図３に戻り、製造装置１は、ドラムコア４に１対のワイヤ５を巻き付けると共に各ワイヤ５の両端部を端子金具６Ａ，６Ｂに巻き付ける（絡げる）動作を自動的に行う装置である。製造装置１は、ドラムコア構造体７を前端面に保持するスピンドル８と、ワイヤ供給部材９及びワイヤホルダ１０を有するワイヤユニット１１とを備えている。   1 to 3, the manufacturing apparatus 1 automatically performs an operation of winding a pair of wires 5 around the drum core 4 and winding (tangling) both ends of each wire 5 around the terminal fittings 6A and 6B. It is. The manufacturing apparatus 1 includes a spindle 8 that holds the drum core structure 7 on the front end surface, and a wire unit 11 that includes a wire supply member 9 and a wire holder 10.

ドラムコア構造体７は、ベースプレート３、ドラムコア４、ワイヤ５及び半田付け前の端子金具６Ａ，６Ｂから構成されている。スピンドル８は、図示しない挟持手段または吸着手段によりドラムコア構造体７を前端面に保持・固定する。また、スピンドル８は、駆動モータ１２により回転駆動される。   The drum core structure 7 includes a base plate 3, a drum core 4, a wire 5, and terminal fittings 6A and 6B before soldering. The spindle 8 holds and fixes the drum core structure 7 to the front end surface by a clamping means or suction means (not shown). The spindle 8 is rotationally driven by a drive motor 12.

ワイヤ供給部材９は、１対のワイヤ５をそれぞれ整列状態で供給する１対のワイヤノズル１３を有している。ワイヤ５は、ワイヤボビン（図示せず）から繰り出されてワイヤノズル１３に導入される。ワイヤホルダ１０は、各ワイヤノズル１３の下端に設けられたワイヤ引き出し開口部から引き出された各ワイヤ５を保持する。ワイヤ供給部材９及びワイヤホルダ１０は、それぞれベアリング１５，１４を介して支持部材１６に回転自在に支持されている。つまり、ワイヤ供給部材９及びワイヤホルダ１０は、支持部材１６を介して一体化されている。   The wire supply member 9 has a pair of wire nozzles 13 for supplying a pair of wires 5 in an aligned state. The wire 5 is fed out from a wire bobbin (not shown) and introduced into the wire nozzle 13. The wire holder 10 holds each wire 5 drawn from a wire drawing opening provided at the lower end of each wire nozzle 13. The wire supply member 9 and the wire holder 10 are rotatably supported by the support member 16 via bearings 15 and 14, respectively. That is, the wire supply member 9 and the wire holder 10 are integrated via the support member 16.

ワイヤユニット１１は、タイミングベルト１７を介してワイヤ供給部材９を回転駆動させる駆動モータ１８を有している。これにより、駆動モータ１８を回転させると、タイミングベルト１７を介して各ワイヤノズル１３が同時に回転するようになる。また、ワイヤユニット１１は、ワイヤホルダ１０の下端部を昇降させることでワイヤホルダ１０を開閉駆動させる開閉駆動機構１９を有している。さらに、ワイヤユニット１１は、支持部材１６を３軸方向（ＸＹＺ方向）に移動させる３軸駆動機構２０を有している。これにより、ワイヤ供給部材９及びワイヤホルダ１０は、一体で３軸方向に移動可能となる。   The wire unit 11 has a drive motor 18 that rotationally drives the wire supply member 9 via a timing belt 17. Thus, when the drive motor 18 is rotated, the wire nozzles 13 are simultaneously rotated via the timing belt 17. Further, the wire unit 11 has an opening / closing drive mechanism 19 that drives the wire holder 10 to open and close by moving the lower end of the wire holder 10 up and down. Furthermore, the wire unit 11 has a triaxial drive mechanism 20 that moves the support member 16 in triaxial directions (XYZ directions). Thereby, the wire supply member 9 and the wire holder 10 are integrally movable in the three axial directions.

ワイヤ供給部材９における各ワイヤノズル１３のワイヤ引き出し開口部の高さ位置は、ワイヤホルダ１０のワイヤ保持部の高さ位置よりも高くなっている。これにより、ワイヤノズル１３のワイヤ引き出し開口部からのワイヤ５の引き出し角度θ（図１参照）が９０度よりも大きくなるため、ワイヤ５に必要以上にテンションがかかることが無い。また、各ワイヤノズル１３を任意に回転させるときに、ワイヤ５がワイヤノズル１３に絡むことも無い。   The height position of the wire drawing opening of each wire nozzle 13 in the wire supply member 9 is higher than the height position of the wire holding portion of the wire holder 10. As a result, the pulling angle θ (see FIG. 1) of the wire 5 from the wire pulling opening of the wire nozzle 13 becomes larger than 90 degrees, so that the wire 5 is not tensioned more than necessary. Further, the wire 5 is not entangled with the wire nozzle 13 when each wire nozzle 13 is arbitrarily rotated.

また、製造装置１は、スピンドル８の手前側からスピンドル８に対して近接・離間自在に配置されたワイヤガイド２１（図１０参照）及びワイヤガイド２２（図１５参照）を更に備えている。   In addition, the manufacturing apparatus 1 further includes a wire guide 21 (see FIG. 10) and a wire guide 22 (see FIG. 15) that are disposed so as to be close to and away from the spindle 8 from the front side of the spindle 8.

ワイヤガイド２１は、ワイヤ５を湾曲させる湾曲部２１ａ（図１２参照）を有し、巻き始め側の端子金具６Ａに各ワイヤ５を巻き付ける際に、各ワイヤ５を端子金具６Ａの長手方向に沿うようにガイドする。ワイヤガイド２２は、ワイヤ５を湾曲させる湾曲部２２ａ（図１７参照）を有し、巻き終わり側の端子金具６Ｂに各ワイヤ５を巻き付ける際に、各ワイヤ５を端子金具６Ｂの長手方向に沿うようにガイドする。   The wire guide 21 has a bending portion 21a (see FIG. 12) that bends the wire 5, and when each wire 5 is wound around the terminal fitting 6A on the winding start side, the wire 5 extends along the longitudinal direction of the terminal fitting 6A. To guide. The wire guide 22 has a bending portion 22a (see FIG. 17) that bends the wire 5, and when each wire 5 is wound around the terminal metal fitting 6B on the winding end side, the wire 5 extends along the longitudinal direction of the terminal metal fitting 6B. To guide.

次に、上記のような製造装置１を用いてドラムコア構造体７に１対のワイヤ５を装着する工程について説明する。   Next, a process of attaching the pair of wires 5 to the drum core structure 7 using the manufacturing apparatus 1 as described above will be described.

なお、スピンドル８及びワイヤユニット１１は、予め図１〜図３に示すような状態となっている。つまり、ワイヤ供給部材９は、スピンドル８の手前上方に配置されている。そして、ワイヤ供給部材９の各ワイヤノズル１３から整列状態で引き出された１対のワイヤ５は、一定のテンションがかかるようにワイヤホルダ１０に保持されている。   The spindle 8 and the wire unit 11 are in a state as shown in FIGS. That is, the wire supply member 9 is disposed in front of the spindle 8. Then, the pair of wires 5 drawn out in an aligned state from the wire nozzles 13 of the wire supply member 9 are held by the wire holder 10 so that a certain tension is applied.

次いで、図５に示すように、支持部材１６を動かして、ワイヤホルダ１０と各ワイヤノズル１３との間に架け渡された各ワイヤ５をドラムコア４の直下位置に配置する。そして、図６に示すように、支持部材１６を矢印Ａに沿って動かすことで、ワイヤホルダ１０と各ワイヤノズル１３との間に架け渡された各ワイヤ５をドラムコア４の巻芯部に引っ掛ける。   Next, as shown in FIG. 5, the support member 16 is moved so that the wires 5 laid between the wire holder 10 and the wire nozzles 13 are arranged at positions immediately below the drum core 4. Then, as shown in FIG. 6, by moving the support member 16 along the arrow A, each wire 5 laid between the wire holder 10 and each wire nozzle 13 is hooked on the core portion of the drum core 4.

次いで、図７に示すように、支持部材１６を矢印Ａに沿って動かすことで、ワイヤホルダ１０側の各ワイヤ５を端子金具６Ａに巻き付け始める。このとき、ワイヤノズル１３側の各ワイヤ５は、ワイヤノズル１３の位置に応じてワイヤノズル１３から出たり入ったりするため、ワイヤ５の動きには支障は無い。   Next, as shown in FIG. 7, by moving the support member 16 along the arrow A, each wire 5 on the wire holder 10 side starts to be wound around the terminal fitting 6A. At this time, each wire 5 on the wire nozzle 13 side exits and enters the wire nozzle 13 in accordance with the position of the wire nozzle 13, so that there is no problem in the movement of the wire 5.

続いて、図８に示すように、ワイヤホルダ１０が端子金具６Ａに対して公転するように支持部材１６を矢印Ａに沿って動かすことで、ワイヤホルダ１０側の各ワイヤ５を更に端子金具６Ａに巻き付けていく。   Subsequently, as shown in FIG. 8, each wire 5 on the wire holder 10 side is further wound around the terminal fitting 6A by moving the support member 16 along the arrow A so that the wire holder 10 revolves with respect to the terminal fitting 6A. To go.

このとき、ワイヤホルダ１０は、フリー回転可能となっているため、各ワイヤ５に引っ張られてテンションのかかる方向に、つまり各ワイヤ５の導入部が端子金具６Ａを向くように自然に回転（自転）するようになる。これにより、２本のワイヤ５は、よじれて重なること無く並んだ状態で端子金具６Ａに巻き付けられることとなる。   At this time, since the wire holder 10 is freely rotatable, the wire holder 10 is naturally rotated (rotated) in a direction in which the wire 5 is pulled and tensioned, that is, the introduction portion of each wire 5 faces the terminal fitting 6A. To come. As a result, the two wires 5 are wound around the terminal fitting 6A in a state where they are aligned without being twisted and overlapped.

また、各ワイヤ５を端子金具６Ａに巻き付ける際には、端子金具６Ａがスピンドル８の前端面に対して手前側へ傾くことにより、端子金具６Ａの根元とベースプレート３との間に各ワイヤ５が入り込む隙間が形成されるので、各ワイヤ５を端子金具６Ａの根元から複数回にわたって巻き付けることが可能となる。   When each wire 5 is wound around the terminal fitting 6A, the terminal fitting 6A is inclined toward the front side with respect to the front end surface of the spindle 8, so that each wire 5 is interposed between the base of the terminal fitting 6A and the base plate 3. Since the clearance gaps are formed, each wire 5 can be wound around the base of the terminal fitting 6A a plurality of times.

そして、図９に示すように、支持部材１６を矢印Ａに沿って動かすことで、各ワイヤ５が端子金具６Ａに必要な巻回数だけ巻き付けられると、図１０に示すように、ワイヤガイド２１がスピンドル８の手前側からスピンドル８に接近してきて端子金具６Ａに接触するようになる。   Then, as shown in FIG. 9, when each wire 5 is wound around the terminal fitting 6A by the necessary number of turns by moving the support member 16 along the arrow A, the wire guide 21 is moved as shown in FIG. It approaches the spindle 8 from the front side of the spindle 8 and comes into contact with the terminal fitting 6A.

続いて、図１１及び図１２に示すように、支持部材１６を矢印Ａに沿って動かすことで、ワイヤノズル１０側の各ワイヤ５をワイヤガイド２１の湾曲部２１ａに倣って湾曲させ、その状態で各ワイヤ５を端子金具６Ａの先端に向けて引き上げる。   Subsequently, as shown in FIGS. 11 and 12, each wire 5 on the wire nozzle 10 side is bent following the bending portion 21a of the wire guide 21 by moving the support member 16 along the arrow A, and this state Then, each wire 5 is pulled up toward the tip of the terminal fitting 6A.

ここで、各ワイヤ５を端子金具６Ａに巻き付ける際に端子金具６Ａがスピンドル８の手前側に傾斜（前述）した場合でも、ワイヤガイド２１が端子金具６Ａをスピンドル８側に押し付けるため、端子金具６Ａがワイヤガイド２１により元の真っ直ぐに近い状態に戻されるようになる。また、ワイヤガイド２１を端子金具６Ａに接触させるだけでなく、各ワイヤ５を端子金具６Ａの先端側に引っ張り上げることによっても、端子金具６Ａの傾斜姿勢を正すことができる。   Here, even when each wire 5 is wound around the terminal fitting 6A, even if the terminal fitting 6A is inclined toward the front side of the spindle 8 (described above), the wire guide 21 presses the terminal fitting 6A toward the spindle 8 side. Is returned to a state close to the original straight by the wire guide 21. Moreover, not only the wire guide 21 is brought into contact with the terminal fitting 6A but also the inclined posture of the terminal fitting 6A can be corrected by pulling up each wire 5 to the tip end side of the terminal fitting 6A.

続いて、端子金具６Ａの先端側において各ワイヤ５をカッタにより切断する（破線Ｃ参照）。これにより、各ワイヤ５の端部は、端子金具６Ａに沿って配置された形状となる。そして、ワイヤガイド２１をスピンドル８から遠ざける。   Subsequently, each wire 5 is cut with a cutter on the distal end side of the terminal fitting 6A (see broken line C). Thereby, the edge part of each wire 5 becomes a shape arrange | positioned along the terminal metal fitting 6A. Then, the wire guide 21 is moved away from the spindle 8.

次いで、図１３に示すように、スピンドル８を回転させることで、各ワイヤノズル１３から引き出された各ワイヤ５をドラムコア４の巻芯部に複数回巻回する。その後、図１４に示すように、ワイヤホルダ１０を開放して、切断後にワイヤホルダ１０で保持していた各ワイヤ５を排出（リリース）する。   Next, as shown in FIG. 13, by rotating the spindle 8, each wire 5 drawn from each wire nozzle 13 is wound around the core portion of the drum core 4 a plurality of times. After that, as shown in FIG. 14, the wire holder 10 is opened, and each wire 5 held by the wire holder 10 after cutting is discharged (released).

次いで、図１４に示すように、各ワイヤノズル１３が端子金具６Ｂに対して公転するように支持部材１６を矢印Ａに沿って動かすことで、各ワイヤノズル１３から引き出された各ワイヤ５を巻き終わり側の端子金具６Ｂに巻き付ける。このとき、ワイヤ供給部材９（１対のワイヤノズル１３）を端子金具６Ｂに対して公転させると同時に、ワイヤ供給部材９を（１対のワイヤノズル１３を一緒に）を各ワイヤ５のテンションのかかる方向に回転（自転）させる（矢印Ｂ参照）。これにより、各ワイヤ５は、よじれて重なること無く並んだ状態で端子金具６Ｂに巻き付けられることとなる。   Next, as shown in FIG. 14, each wire 5 drawn from each wire nozzle 13 is wound by moving the support member 16 along the arrow A so that each wire nozzle 13 revolves with respect to the terminal fitting 6B. Wind around the terminal fitting 6B on the end side. At this time, the wire supply member 9 (a pair of wire nozzles 13) is revolved with respect to the terminal fitting 6B, and at the same time, the wire supply member 9 (with the pair of wire nozzles 13 together) Rotate (rotate) in this direction (see arrow B). Thereby, each wire 5 will be wound around the terminal metal fitting 6B in the state where it arranged without twisting and overlapping.

また、端子金具６Ａへの各ワイヤ５の巻き付け動作と同様に、各ワイヤ５を端子金具６Ｂに巻き付ける際に、端子金具６Ｂがスピンドル８の前端面に対して手前側へ傾くことにより、端子金具６Ｂの根元とベースプレート３との間に各ワイヤ５が入り込む隙間が形成されるので、各ワイヤ５を端子金具６Ｂの根元から複数回にわたって巻き付けることが可能となる。   Similarly to the winding operation of each wire 5 around the terminal fitting 6A, when each wire 5 is wound around the terminal fitting 6B, the terminal fitting 6B is inclined toward the front side with respect to the front end surface of the spindle 8, thereby Since a gap is formed between each base wire 6B and the base plate 3, the wires 5 can be wound around the base of the terminal fitting 6B a plurality of times.

そして、各ワイヤ５が端子金具６Ｂに必要な巻回数だけ巻き付けられると、図１５に示すように、ワイヤガイド２２がスピンドル８の手前側からスピンドル８に接近してきて端子金具６Ｂに接触するようになる。   When each wire 5 is wound around the terminal fitting 6B as many times as necessary, the wire guide 22 approaches the spindle 8 from the front side of the spindle 8 and contacts the terminal fitting 6B as shown in FIG. Become.

続いて、図１６及び図１７に示すように、支持部材１６を矢印Ａに沿って動かすことで、各ワイヤ５をワイヤガイド２２の湾曲部２２ａに倣って湾曲させ、その状態で各ワイヤ５を端子金具６Ｂの先端に向けて引き上げる。   Subsequently, as shown in FIGS. 16 and 17, by moving the support member 16 along the arrow A, each wire 5 is bent following the bending portion 22 a of the wire guide 22, and in this state, each wire 5 is moved. Pull up toward the tip of the terminal fitting 6B.

ここで、端子金具６Ａへの各ワイヤ５の巻き付け動作と同様に、ワイヤガイド２２が端子金具６Ｂを押し付けると共に、各ワイヤ５を端子金具６Ｂの先端側に引っ張り上げることにより、各ワイヤ５の巻き付け時に傾斜した端子金具６Ｂが元の真っ直ぐに近い状態に戻されるようになる。   Here, similarly to the winding operation of each wire 5 around the terminal metal fitting 6A, the wire guide 22 presses the terminal metal fitting 6B, and each wire 5 is pulled up to the distal end side of the terminal metal fitting 6B. The terminal fitting 6B that is sometimes inclined is returned to the original straight state.

続いて、図１８に示すように、支持部材１６を矢印Ａに沿って動かすことで、ワイヤガイド２２と各ワイヤノズル１３との間に延びる各ワイヤ５をワイヤホルダ１０に保持し、その状態で、端子金具６Ｂの先端側において各ワイヤ５をカッタにより切断する（破線Ｃ参照）。これにより、各ワイヤ５の端部は、端子金具６Ｂに沿って配置された形状となる。そして、ワイヤガイド２２をスピンドル８から遠ざける。   Subsequently, as shown in FIG. 18, by moving the support member 16 along the arrow A, each wire 5 extending between the wire guide 22 and each wire nozzle 13 is held in the wire holder 10, and in this state, Each wire 5 is cut with a cutter at the tip end side of the terminal fitting 6B (see broken line C). Thereby, the edge part of each wire 5 becomes a shape arrange | positioned along the terminal metal fitting 6B. Then, the wire guide 22 is moved away from the spindle 8.

以上により、ドラムコア構造体７に１対のワイヤ５を装着する動作が完了する。その後、各ワイヤ５と端子金具６Ａ，６Ｂとを半田で接合し、端子金具６Ａ，６Ｂの先端部分をカットすることで、図４に示すようなコイル部品２が得られる。   Thus, the operation of attaching the pair of wires 5 to the drum core structure 7 is completed. Thereafter, the wires 5 and the terminal fittings 6A and 6B are joined by soldering, and the tip parts of the terminal fittings 6A and 6B are cut, whereby the coil component 2 as shown in FIG. 4 is obtained.

ところで、ワイヤ供給部材９とワイヤホルダ１０とが独立して自由に移動可能な構成となっている場合には、まず１対のワイヤ５をドラムコア４の巻芯部に巻回してから、各ワイヤ５の両端部を端子金具６Ａ，６Ｂに巻き付ければ良く、この方法によれば１対のワイヤ５を整列状態に維持することは特に困難ではない。しかし、ワイヤ供給部材９及びワイヤホルダ１０を駆動する機構が別々に必要となるため、製造装置の構成が複雑化してしまう。   By the way, when the wire supply member 9 and the wire holder 10 are configured to be freely movable independently, first, a pair of wires 5 are wound around the core portion of the drum core 4 and then each wire 5 It is sufficient to wind both ends of the wire around the terminal fittings 6A and 6B, and according to this method, it is not particularly difficult to maintain the pair of wires 5 in an aligned state. However, since a mechanism for driving the wire supply member 9 and the wire holder 10 is required separately, the configuration of the manufacturing apparatus becomes complicated.

本実施形態では、ワイヤ供給部材９とワイヤホルダ１０とを一体で３軸方向に移動可能な構成としている。ただし、この場合には、最初に１対のワイヤ５をドラムコア４の巻芯部に巻回することは困難となるため、まず各ワイヤ５を巻き始め側の端子金具６Ａに巻き付けてから、各ワイヤ５をドラムコア４の巻芯部に巻回し、その後に各ワイヤ５を巻き終わり側の端子金具６Ｂに巻き付けることとなる。この手法では、各ワイヤノズル１３がドラムコア４に接近して動きの自由度が奪われる方向へのワイヤ巻き付け動作となるため、何らかの工夫をしないと、各ワイヤ５を整列状態で巻き付けることが困難になる。１対のワイヤ５が整列状態とならずによじれ重なると、ワイヤ５と端子金具６Ａ，６Ｂとの間に隙間が生じるため、半田が端子金具６Ａ，６Ｂ上にうまく塗られないことがある。   In the present embodiment, the wire supply member 9 and the wire holder 10 are integrally movable in the three axial directions. However, in this case, since it is difficult to first wind the pair of wires 5 around the core portion of the drum core 4, each wire 5 is first wound around the terminal fitting 6A on the winding start side. The wire 5 is wound around the core part of the drum core 4, and then each wire 5 is wound around the terminal fitting 6B on the winding end side. In this method, since each wire nozzle 13 approaches the drum core 4 and becomes a wire winding operation in a direction in which the degree of freedom of movement is taken away, it is difficult to wind each wire 5 in an aligned state unless some measures are taken. Become. When the pair of wires 5 are twisted and overlapped without being aligned, a gap is formed between the wire 5 and the terminal fittings 6A and 6B, and thus solder may not be applied well onto the terminal fittings 6A and 6B.

これに対し本実施形態においては、１対のワイヤ５を保持するワイヤホルダ１０はフリー回転自在であるので、各ワイヤ５を巻き始め側の端子金具６Ａに巻き付けるべく、ワイヤホルダ１０を端子金具６Ａに対して公転するように動かすと、ワイヤホルダ１０は各ワイヤ５に引っ張られてテンションのかかる方向に自然に回転（自転）する。これにより、各ワイヤ５を端子金具６Ａに巻き付けるときに、各ワイヤ５がよじれて重なることが無いため、各ワイヤノズル１３がドラムコア４に接近して動きの自由度が奪われる方向へのワイヤ巻き付け動作となる場合でも、各ワイヤ５は整列状態に維持されるようになる。また、各ワイヤ５を巻き終わり側の端子金具６Ｂに巻き付けるときには、ワイヤ供給部材９を端子金具６Ｂに対して公転するように動かすと同時に、ワイヤ供給部材９をワイヤ５のテンションのかかる方向に回転（自転）させるので、同様に各ワイヤ５がよじれて重なることが無く、各ワイヤ５は整列状態に維持される。   On the other hand, in the present embodiment, the wire holder 10 holding the pair of wires 5 is freely rotatable. Therefore, in order to wind each wire 5 around the terminal fitting 6A on the winding start side, the wire holder 10 is attached to the terminal fitting 6A. When the wire holder 10 is moved so as to revolve, the wire holder 10 is pulled by each wire 5 and naturally rotates (spins) in the direction in which the tension is applied. Thereby, when each wire 5 is wound around the terminal fitting 6A, each wire 5 is not twisted and overlapped. Therefore, each wire nozzle 13 approaches the drum core 4 and is wound in a direction in which freedom of movement is taken away. Even in the operation, the wires 5 are maintained in the aligned state. Further, when each wire 5 is wound around the terminal fitting 6B on the winding end side, the wire supply member 9 is moved so as to revolve with respect to the terminal fitting 6B, and at the same time, the wire supply member 9 is rotated in the direction in which the wire 5 is tensioned. (Spinning) Since each wire 5 is not twisted and overlapped similarly, each wire 5 is maintained in an aligned state.

これにより、ワイヤ供給部材９とワイヤホルダ１０とを一体化した場合でも、各ワイヤ５を整列状態でドラムコア４及び端子金具６Ａ，６Ｂに巻き付けることができる。その結果、各ワイヤ５を端子金具６Ａ，６Ｂに半田で接合する際に、半田が端子金具６Ａ，６Ｂ上に十分にうまく塗られるようになるため、各ワイヤ５と端子金具６Ａ，６Ｂとを半田で良好に継線することができる。また、ワイヤ供給部材９及びワイヤホルダ１０を別々に駆動する構成としなくて済むため、製造装置１の構成を簡単化し、自動機として構成しやすくなる。   Thereby, even when the wire supply member 9 and the wire holder 10 are integrated, each wire 5 can be wound around the drum core 4 and the terminal fittings 6A and 6B in an aligned state. As a result, when the wires 5 are joined to the terminal fittings 6A and 6B with solder, the solder is sufficiently satisfactorily applied onto the terminal fittings 6A and 6B. Therefore, the wires 5 and the terminal fittings 6A and 6B are connected to each other. Good connection with solder. Moreover, since it is not necessary to drive the wire supply member 9 and the wire holder 10 separately, the configuration of the manufacturing apparatus 1 is simplified and it is easy to configure as an automatic machine.
