By the way, in the so-called wave-winding motor, as shown in FIG. 10, the conductive wire forming the coil is formed in the radial waveform winding 3 having an annular waveform shape in advance to be inserted into the slot 2 of the stator core 1. It is necessary to keep. When the radial corrugated winding 3 is mounted on the stator core 1, the radial corrugated winding 3 is inserted into the slot 2 by the punch 5 with a plurality of blades 4 applied to the inner curved portion 6.
このように導線を円環状の波形形状に形成するために、波形形状の内側湾曲部６に対応する複数の第１支柱と、外側湾曲部７に対応する複数の第２支柱とをそれぞれ回転テーブル上に円環状に配置し、第１支柱及び第２支柱に導線を交互に巻き付ける装置が提案されている（例えば、特許文献１参照）。 Thus, in order to form a conducting wire in an annular corrugated shape, a plurality of first struts corresponding to the corrugated inner curved portion 6 and a plurality of second struts corresponding to the outer curved portion 7 are respectively rotated tables. There has been proposed a device that is arranged in an annular shape and winds conductive wires alternately around a first support column and a second support column (see, for example, Patent Document 1).

The engagement piece 56 is a part of the height adjustment mechanism 58, and the engagement piece 56 can be advanced and retracted by operating the operation unit 60, and the engagement piece 56 is retracted from the annular groove 54. In this state, the nozzle 48 is moved up and down, and when it reaches an appropriate position, the operation portion 60 is operated to set the height of the nozzle 48, and the amount of protrusion of the tip portion 50 downward is adjusted.
本体部５２はベアリング６２によってノズル支持部材４６に対して回転自在となっており、さらに、ノズル４８の後端であるキャップ部６４は、本体部５２に対してベアリング６６によって回転自在となっている。 The main body 52 is rotatable with respect to the nozzle support member 46 by a bearing 62, and the cap portion 64, which is the rear end of the nozzle 48, is freely rotatable with respect to the main body 52 by a bearing 66. .
キャップ部６４の上面中心部には孔６８が設けられ、該孔６８よりも外周側の一箇所には垂直面上において回転可能な第１ローラ７０が設けられている。本体部５２は中空円筒構造となっており、導線供給部２０（図１参照）から供給された導線１２は、第１ローラ７０及び孔６８を介して本体部５２の中空部に導かれる。このとき、キャップ部６４はベアリング６６により回転自在であることからノズル４８がいかなる位置にあっても第１ローラ７０は導線供給部２０の方向を向くことになり、導線１２を適切に導入することができる。 A hole 68 is provided at the center of the upper surface of the cap part 64, and a first roller 70 that is rotatable on a vertical surface is provided at one location on the outer peripheral side of the hole 68. The main body portion 52 has a hollow cylindrical structure, and the conductive wire 12 supplied from the conductive wire supply portion 20 (see FIG. 1) is guided to the hollow portion of the main body portion 52 through the first roller 70 and the hole 68.

先端部５０には、垂直面上で回転可能な第２ローラ（第１導線ガイド部）７２と、略水平な孔７４ａを有するリング（第２導線ガイド部）７４が設けられている。ノズル４８において、導線１２は第１ローラ７０、第２ローラ７２及びリング７４の順に導かれる。第２ローラ７２は、前記第１ローラ７０を経由して下方に向かって案内された導線１２を水平方向よりやや上方に向かってリング７４の孔７４ａに入るように案内する。つまり、第２ローラ７２の下部よりも孔７４ａの最下部の方がやや高い位置に設定されており、導線１２は、第２ローラ７２によって図４の時計方向（矢印Ｃ方向）に曲げられた後、孔７４ａの最下部における端点７４ｂで図４の反時計方向（矢印Ｄ方向）に曲げられることから、それぞれ逆の回転方向に曲げられる。これにより、導線１２に対する曲げ変形が矯正されて、導線１２を曲がり癖のない真っ直ぐな状態で第１支柱１４及び第２支柱１６に供給することができる。また、第２ローラ７２の径を小さく設定することが可能になり、先端部５０をコンパクトにすることができる。 The distal end portion 50 is provided with a second roller (first conducting wire guide portion) 72 that can rotate on a vertical plane and a ring (second conducting wire guide portion) 74 having a substantially horizontal hole 74a. In the nozzle 48, the conducting wire 12 is guided in the order of the first roller 70, the second roller 72, and the ring 74. The second roller 72 guides the conducting wire 12 guided downward via the first roller 70 so as to enter the hole 74a of the ring 74 slightly upward from the horizontal direction. That is, the lowermost part of the hole 74a is set at a slightly higher position than the lower part of the second roller 72, and the conductive wire 12 is bent in the clockwise direction (arrow C direction) in FIG. 4 by the second roller 72. After that, since it is bent in the counterclockwise direction (arrow D direction) in FIG. 4 at the end point 74b at the lowermost portion of the hole 74a, it is bent in the opposite rotational direction. Thereby, the bending deformation | transformation with respect to the conducting wire 12 is corrected, and the conducting wire 12 can be supplied to the 1st support | pillar 14 and the 2nd support | pillar 16 in a straight state without a bend. Moreover, it becomes possible to set the diameter of the 2nd roller 72 small, and the front-end | tip part 50 can be made compact.
なお、図５に示すように、第２ローラ７２と同じ平面上で回転可能な第３ローラ７６を前記リング７４の位置に設け、第２ローラ７２及び第３ローラ７６によって導線１２に対する曲げ変形を矯正させてもよい。 As shown in FIG. 5, a third roller 76 that can rotate on the same plane as the second roller 72 is provided at the position of the ring 74, and the lead wire 12 is bent and deformed by the second roller 72 and the third roller 76. It may be corrected.
第２ローラ７２及びリング７４を経由した導線１２は、水平な向きとなって第１支柱１４又は第２支柱１６に供給されるが、この際、本体部５２はベアリング６２により回転自在であることから、ノズル４８がいかなる位置にあってもリング７４は導線１２の供給先である第１支柱１４又は第２支柱１６の方向を向くことになり、導線１２を適切に導出することができる。 The conducting wire 12 passing through the second roller 72 and the ring 74 is supplied to the first support column 14 or the second support column 16 in a horizontal orientation. At this time, the main body 52 is rotatable by a bearing 62. Therefore, the ring 74 faces the direction of the first support column 14 or the second support column 16 to which the conductive wire 12 is supplied regardless of the position of the nozzle 48, and the conductive wire 12 can be appropriately led out.
図１に戻り、導線供給部２０は巻線治具１８からみて矢印Ａ方向の一端方向（矢印Ａ２方向）に設けられており、導線１２が巻回された６つのリール８０と、該リール８０の上部に配置されて、各リール８０からノズル４８に対して導線１２を弛みなく供給するための６つのテンショナ８２とを有する。このように、導線供給部２０は巻線治具１８の一端である矢印Ａ２方向に設けられていることから、ノズル４８からみて６本の導線１２は常に略同じ方向から供給されることになり、各導線１２の曲がり具合を常に均一な状態に揃えることができる。従って、第１支柱１４及び第２支柱１６に６本の導線１２を均一な状態に巻回することができる。 Returning to FIG. 1, the conductive wire supply unit 20 is provided in one end direction (arrow A2 direction) in the direction of arrow A when viewed from the winding jig 18, and six reels 80 around which the conductive wire 12 is wound, and the reel 80 6 tensioners 82 for supplying the lead wire 12 from each reel 80 to the nozzle 48 without slack. Thus, since the conducting wire supply unit 20 is provided in the direction of the arrow A2 that is one end of the winding jig 18, the six conducting wires 12 are always supplied from substantially the same direction when viewed from the nozzle 48. The bending state of each conductor 12 can be always made uniform. Therefore, the six conducting wires 12 can be wound around the first support column 14 and the second support column 16 in a uniform state.
次に、このように構成される波形巻線形成装置１０を用いて、導線１２を波形形状である放射状波形巻線１００（図８参照）に形成する波形巻線形成方法及び放射状波形巻線１００をステータコア１０２に挿入する方法について図６〜図９を参照しながら説明する。 Next, using the waveform winding forming apparatus 10 configured as described above, the waveform winding forming method and the radial waveform winding 100 for forming the conductive wire 12 into a waveform having a waveform shape (see FIG. 8). Will be described with reference to FIGS. 6 to 9.
先ず、ステップＳ１において、リニアガイド４０を巻線治具１８における矢印Ａ１方向の端部まで移動させるとともに、高さ調整機構５８によってノズル４８の先端部５０を十分に下げる。また、導線供給部２０において、各リール８０から導線１２を引き出し、各テンショナ８２、第１ローラ７０、第２ローラ７２及びリング７４を通しておく。 First, in step S <b> 1, the linear guide 40 is moved to the end of the winding jig 18 in the direction of arrow A <b> 1, and the tip 50 of the nozzle 48 is sufficiently lowered by the height adjustment mechanism 58. Further, in the conducting wire supply unit 20, the conducting wire 12 is pulled out from each reel 80 and passed through each tensioner 82, first roller 70, second roller 72, and ring 74.
次に、ステップＳ２において、６本の導線１２の端部を巻線治具１８における矢印Ａ１方向の端部に設けられた開始係合部８６に係合する。 Next, in step S <b> 2, the end portions of the six conducting wires 12 are engaged with the start engagement portion 86 provided at the end portion in the arrow A <b> 1 direction of the winding jig 18.
次いで、ステップＳ３において、リニアガイド４０を矢印Ａ２方向に手動で移動させるとともに移動ブロック４４を矢印Ｂ方向に往復動させながら、６本の導線１２を第１支柱１４及び第２支柱１６に対して交互に巻き付ける。 Next, in step S3, the six conductors 12 are moved relative to the first support column 14 and the second support column 16 while manually moving the linear guide 40 in the direction of arrow A2 and reciprocating the moving block 44 in the direction of arrow B. Wrap alternately.
この処理を具体的に説明するために、図２に示すように、複数の第１支柱１４を矢印Ａ１方向の端部から逆の矢印Ａ２方向に向かって第１支柱１４ａ、１４ｂ、１４ｃ、１４ｄ…とし、同様に、複数の第２支柱１６を第２支柱１６ａ、１６ｂ、１６ｃ、１６ｄ…として区別する。先ず、ノズル４８を第１支柱１４ａの外側に回し、第１支柱１４ａと第１支柱１４ｂとの間を通す。次に、ノズル４８を第２支柱１６ａの外側に回し、第２支柱１６ａと第２支柱１６ｂとの間を通す。この後、同様にノズル４８を第１支柱１４ｂ、第２支柱１６ｂ、第１支柱１４ｃ及び第２支柱１６ｃの外側を通す。 In order to specifically describe this process, as shown in FIG. 2, the first support columns 14a, 14b, 14c, and 14d are moved from the end in the arrow A1 direction toward the reverse arrow A2 direction. .., And similarly, the plurality of second support columns 16 are distinguished as second support columns 16a, 16b, 16c, 16d,. First, the nozzle 48 is turned to the outside of the first support column 14a to pass between the first support column 14a and the first support column 14b. Next, the nozzle 48 is turned to the outside of the second support column 16a to pass between the second support column 16a and the second support column 16b. Thereafter, the nozzle 48 is similarly passed through the first column 14b, the second column 16b, the first column 14c, and the second column 16c.
この段階で、第１転位区切り巻線部３４ａに対する導線１２の巻き付けが終了し、次に、リニアガイド４０を矢印Ａ２方向に距離ｄ３だけ移動させて第２転位区切り巻線部３４ｂに対する導線１２の巻き付けを行う。この際、第２支柱１６ｄの外側を通してから第１支柱１４ｄの外側を通すようにノズル４８を移動させる。つまり、ノズル４８は、第２支柱１６ｃを経由した後にさらに第２支柱１６ｄを経由してから第１支柱１４ｄに向かうこととなり、第２支柱１６ｃと第２支柱１６ｄとの間に距離ｄ３の第１転位箇所８８ａを形成する。 At this stage, the winding of the conducting wire 12 around the first dislocation separating winding portion 34a is completed, and then the linear guide 40 is moved by a distance d3 in the direction of arrow A2 to move the conducting wire 12 to the second dislocation separating winding portion 34b. Wrap. At this time, the nozzle 48 is moved so as to pass through the outside of the first column 14d after passing through the outside of the second column 16d. In other words, after passing through the second column 16c, the nozzle 48 further passes through the second column 16d and then moves toward the first column 14d, and the nozzle 48 has a distance d3 between the second column 16c and the second column 16d. One dislocation point 88a is formed.
この後、同様に第２〜第５転位区切り巻線部３４ｂ〜３４ｅの第１支柱１４及び第２支柱１６に対して導線１２の巻き付けを行い、第２転位箇所８８ｂ、第３転位箇所８８ｃ及び第４転位箇所８８ｄを形成する。 Thereafter, similarly, the conductive wire 12 is wound around the first support column 14 and the second support column 16 of the second to fifth dislocation separating winding portions 34b to 34e, and the second dislocation portion 88b, the third dislocation portion 88c, and A fourth dislocation location 88d is formed.
次に、ステップＳ４において、第５転位区切り巻線部３４ｅまで巻き付けの終わった６本の導線１２を切断し、その端部を巻線治具１８における矢印Ａ２方向の端部に設けられた終了係合部９０に係合する。 Next, in step S4, the six conducting wires 12 that have been wound up to the fifth dislocation separating winding 34e are cut, and the ends thereof are provided at the ends of the winding jig 18 in the direction of the arrow A2. Engage with the engaging portion 90.
次いで、ステップＳ５において、巻き付けを行った回数を確認し、該回数がＮ回（例えば、２０回）未満であればステップＳ６へ移り、回数がＮ回に達していればステップＳ７に移る。 Next, in step S5, the number of windings is confirmed. If the number is less than N (for example, 20), the process proceeds to step S6, and if the number has reached N, the process proceeds to step S7.
ステップＳ６においては、リニアガイド４０を巻線治具１８における矢印Ａ１方向の端部まで移動させるとともに、高さ調整機構５８を操作することによってノズル４８の先端部５０を所定高さだけ上昇させる。この後、前記ステップＳ２に戻り６本の導線１２の端部を開始係合部８６に係合して２回目以降の導線１２の巻き付けを行う。高さ調整機構５８によって導線１２の高さを変えながら複数回巻き付け作業を行うことにより、導線１２の束を帯状に形成することができる。 In step S6, the linear guide 40 is moved to the end of the winding jig 18 in the direction of the arrow A1, and the height adjusting mechanism 58 is operated to raise the tip end 50 of the nozzle 48 by a predetermined height. Thereafter, the process returns to step S2, and the ends of the six conducting wires 12 are engaged with the start engaging portion 86, and the conducting wires 12 are wound for the second and subsequent times. By performing the winding operation a plurality of times while changing the height of the conducting wire 12 by the height adjusting mechanism 58, the bundle of conducting wires 12 can be formed in a strip shape.
ところで、導線１２の巻き付けを行う方法として、奇数回目の導線１２の巻き付け処理を矢印Ａ２方向へ向かって行うとともに、偶数回目の導線１２の巻き付け処理を矢印Ａ１方向へ向かって行うという往復式の方法も考えられる。しかしながら、この方法では、往復時に導線供給部２０からノズル４８に対する導線１２の供給垂直角度θ（図１参照）の変化が異なる。つまり、矢印Ａ２方向に向かって導線１２の巻き付けを行うときには、供給垂直角度θは次第に大きくなるように変化するのに対して、矢印Ａ１方向に向かって導線１２の巻き付けを行うときには、供給垂直角度θは次第に減少する。 By the way, as a method of winding the conducting wire 12, a reciprocating method in which the winding processing of the odd-numbered conducting wire 12 is performed in the direction of the arrow A2 and the winding processing of the even-numbered conducting wire 12 is performed in the direction of the arrow A1. Is also possible. However, in this method, the change in the supply vertical angle θ (see FIG. 1) of the conducting wire 12 from the conducting wire supply unit 20 to the nozzle 48 differs during reciprocation. That is, when the conductor 12 is wound in the direction of the arrow A2, the supply vertical angle θ is gradually increased, whereas when the conductor 12 is wound in the direction of the arrow A1, the supply vertical angle is θ gradually decreases.
また、導線１２はテンショナ８２によって張力が一定となるように調整されているが、実際上はテンショナ８２とノズル４８との位置関係によって張力が多少変化することがある。例えば、矢印Ａ２方向に向かって導線１２の巻き付けを行うときに導線１２の張力はやや減少し、矢印Ａ１方向に向かって導線１２の巻き付けを行うときには張力はやや増加することがある。 Further, although the lead wire 12 is adjusted by the tensioner 82 so that the tension becomes constant, in practice, the tension may slightly change depending on the positional relationship between the tensioner 82 and the nozzle 48. For example, the tension of the conductor 12 may slightly decrease when the conductor 12 is wound in the direction of the arrow A2, and the tension may slightly increase when the conductor 12 is wound in the direction of the arrow A1.
このように、偶数回目の導線１２の巻き付けを矢印Ａ１方向へ向かって行う場合、奇数回目の導線１２の巻き付けを矢印Ａ２方向へ向かって行う場合と比較して導線１２の供給角度の変化や張力の変化具合が異なり、導線１２の曲がり癖が変わることとなり、導線１２を第１支柱１４及び第２支柱１６に対して均一に巻き付けることができない。 Thus, when the winding of the even-numbered conductor 12 is performed in the direction of the arrow A1, the change in the supply angle of the conductor 12 and the tension are compared with the case where the winding of the odd-numbered conductor 12 is performed in the direction of the arrow A2. However, the bending of the conductive wire 12 changes, and the conductive wire 12 cannot be uniformly wound around the first support column 14 and the second support column 16.
本実施の形態に係る波形巻線形成方法では、導線１２の巻き付けを矢印Ａ２方向にのみ繰り返して行うことから導線１２の曲がり癖が一定であり、形成される波形の各導線１２は均一に整列される。なお、逆に、導線１２の巻き付けを矢印Ａ１方向にのみ繰り返して行うようにしても同様の効果が得られる。 In the corrugated winding forming method according to the present embodiment, since the winding of the conducting wire 12 is repeated only in the direction of the arrow A2, the bending curve of the conducting wire 12 is constant, and the conducting wires 12 of the formed waveform are uniformly aligned. Is done. On the contrary, the same effect can be obtained even if the winding of the conducting wire 12 is repeated only in the direction of the arrow A1.
次に、ステップＳ７（巻き付け回数がＮ回に達したとき）においては、第１〜第５転位区切り巻線部３４ａ〜３４ｅの第１支柱１４及び第２支柱１６に巻き付けられた導線１２に対して適当な間隔でシール９２を巻き付けて仮固定し、導線１２を上方に引き上げて巻線治具１８から抜き取る（図７参照）。このようにして導線１２は波形形状に形成される。 Next, in step S7 (when the number of windings reaches N), for the conductor 12 wound around the first support column 14 and the second support column 16 of the first to fifth dislocation separating winding portions 34a to 34e. Then, the seal 92 is wound and temporarily fixed at an appropriate interval, and the conducting wire 12 is pulled upward and removed from the winding jig 18 (see FIG. 7). Thus, the conducting wire 12 is formed in a waveform shape.
次に、ステップＳ８において、波形形状に形成された導線１２をさらに環状に丸めて、放射状波形巻線１００を形成する。すなわち、図８に示すように、６つの外側湾曲部９４ａ、９４ｂ、９４ｃ、９４ｄ、９４ｅ及び９４ｆと内側湾曲部９６ａ、９６ｂ、９６ｃ、９６ｄ、９６ｅ及び９６ｆを形作るように導線１２を丸めて放射状波形巻線１００を形成する。 Next, in step S <b> 8, the conductive wire 12 formed in a waveform shape is further rounded into a ring shape to form the radial waveform winding 100. That is, as shown in FIG. 8, the conductor 12 is rounded to form six outer curved portions 94a, 94b, 94c, 94d, 94e and 94f and inner curved portions 96a, 96b, 96c, 96d, 96e and 96f. A wave winding 100 is formed.
放射状波形巻線１００は、波形に形成された巻線が縦方向に４層に積層されて形成されている。具体的には、第１転位区切り巻線部３４ａ及び第２転位区切り巻線部３４ｂの前半が図８における最上層の第１層目を形成し、第２転位区切り巻線部３４ｂの後半及び第３転位区切り巻線部３４ｃの前半が第２層目を形成する。同様に、第３転位区切り巻線部３４ｃの後半及び第４転位区切り巻線部３４ｄの前半が第３層目を形成し、第４転位区切り巻線部３４ｄの後半及び第５転位区切り巻線部３４ｅが第４層目を形成する。 The radial corrugated winding 100 is formed by laminating four windings formed in a corrugated shape in the vertical direction. Specifically, the first half of the first dislocation separating winding portion 34a and the second dislocation separating winding portion 34b form the first layer of the uppermost layer in FIG. 8, and the second half of the second dislocation separating winding portion 34b and The first half of the third dislocation separating winding part 34c forms the second layer. Similarly, the latter half of the third dislocation separating winding portion 34c and the first half of the fourth dislocation separating winding portion 34d form the third layer, and the latter half of the fourth dislocation separating winding portion 34d and the fifth dislocation separating winding portion 34d. The portion 34e forms the fourth layer.
また、第１〜第４転位箇所８８ａ〜８８ｄは、それぞれ１８０°捻られて転位しており、この転位により６本の導線１２の導電度等に個体差がある場合にもそのばらつきが相殺される。さらに、前記の通り、第１〜第４転位箇所８８ａ〜８８ｄは間隔ｄ２よりもやや長い距離ｄ３（図１参照）の長さが確保されていることから、１８０°捻られてもその部分の長さが不足するということがない。 In addition, the first to fourth dislocation locations 88a to 88d are each twisted by 180 °, and the dislocation cancels out even when there are individual differences in the conductivity of the six conductors 12 due to the dislocation. The Furthermore, as described above, the first to fourth dislocation locations 88a to 88d have a distance d3 (see FIG. 1) slightly longer than the distance d2, so that even if the first to fourth dislocation locations 88a to 88d are twisted 180 °, There is no shortage of length.
次に、ステップＳ９において、放射状波形巻線１００の内側湾曲部９６ａ〜９６ｆの部分をステータコア１０２の内径に合うように複数のブレード１０３（図８参照）を当てておき、図示しないパンチ（又はスライダーとも呼ばれる）により放射状波形巻線１００をステータコア１０２のスロット１０４に挿入する（図９参照）。これにより、内側湾曲部９６ａ〜９６ｆがステータコア１０２の一端面に配置され、外側湾曲部９４ａ〜９４ｆがステータコア１０２の他端面に配置されることになる。なお、図９は、ステータコア１０２に１つの放射状波形巻線１００を挿入した状態を示しているが、このステータコア１０２は３相モータ用のものであり、さらに別の２つの放射状波形巻線１００を用意しておき、空いているスロット１０４に互いの位相が１２０°ずれるようにして残りの２つの放射状波形巻線１００を挿入すればよい。 Next, in step S9, a plurality of blades 103 (see FIG. 8) are applied so that the inner curved portions 96a to 96f of the radial corrugated winding 100 are aligned with the inner diameter of the stator core 102, and a punch (or slider) (not shown). The radial corrugated winding 100 is inserted into the slot 104 of the stator core 102 (refer to FIG. 9). As a result, the inner curved portions 96 a to 96 f are disposed on one end surface of the stator core 102, and the outer curved portions 94 a to 94 f are disposed on the other end surface of the stator core 102. FIG. 9 shows a state in which one radial waveform winding 100 is inserted into the stator core 102. This stator core 102 is for a three-phase motor, and two other radial waveform windings 100 are provided. The remaining two radial waveform windings 100 may be inserted into the vacant slot 104 so that the phases thereof are shifted by 120 °.
このようにして３つの放射状波形巻線１００がコイルとして挿入されたステータコア１０２は、図示しないロータと組み合わされて３相モータを構成する。この３相モータは、コイルを形成する導線１２の束が適当な間隔で転位していることから、導線１２の個体差が相殺されて良好な磁界を発生することができる。 The stator core 102 in which the three radial waveform windings 100 are inserted as coils in this manner is combined with a rotor (not shown) to constitute a three-phase motor. In this three-phase motor, since the bundle of the conducting wires 12 forming the coil is shifted at an appropriate interval, the individual difference of the conducting wires 12 is canceled and a good magnetic field can be generated.
上記の実施例では、放射状波形巻線１００が４層である例について示したが、例えば、３層で足りる場合には、前記ステップＳ３において、１層分少ない箇所に対応する第１支柱１４ｓ（図２参照）まで導線１２の巻き付けを行い、これに対応した適当な係合部に切断した導線１２の端部を係合させればよい。 In the above-described embodiment, an example in which the radial corrugated winding 100 has four layers has been described. However, for example, when three layers are sufficient, in the step S3, the first support column 14s ( The conductor 12 may be wound up to (see FIG. 2), and the end of the cut conductor 12 may be engaged with an appropriate engaging portion corresponding thereto.
また、ステータコア１０２の高さＨ（図９参照）が異なる場合には、クランプ３２（図１参照）を操作することによって、板材２４と板材２６との距離を調整すればよく、ステータコア１０２の極数やスロット１０４の形状が異なる場合には、各第１支柱１４及び各第２支柱１６の位置を調整すればよい。 If the height H (see FIG. 9) of the stator core 102 is different, the distance between the plate material 24 and the plate material 26 may be adjusted by operating the clamp 32 (see FIG. 1). When the numbers and the shapes of the slots 104 are different, the positions of the first pillars 14 and the second pillars 16 may be adjusted.
さらに、上記の実施例では、リニアガイド４０及び移動ブロック４４を手動で動かすものとして説明したが、これらの移動機構に適当なアクチュエータを設け、コントローラの制御下に自動運転するようにしてもよい。 Further, in the above-described embodiment, the linear guide 40 and the moving block 44 are described as being manually moved. However, an appropriate actuator may be provided in these moving mechanisms, and automatic operation may be performed under the control of the controller.
上述したように、本実施の形態に係る波形巻線形成装置１０によれば、平行に並べられた複数の第１支柱１４と第２支柱１６に導線１２を交互に巻き付けることにより、スロット１０４の数及び形状が異なる種々のステータコア１０２に対応可能なように、導線１２を種々の波形形状に形成することができる。 As described above, according to the corrugated winding forming apparatus 10 according to the present embodiment, the conductive wires 12 are alternately wound around the plurality of first support columns 14 and second support columns 16 arranged in parallel, thereby The lead wire 12 can be formed in various corrugated shapes so as to be compatible with various stator cores 102 having different numbers and shapes.
また、リング７４又は第３ローラ７６によって、第２ローラ７２を通過した導線１２の曲がり癖を矯正することができるので、導線１２を均一に整列させることができる。 Moreover, since the bending wrinkles of the conducting wire 12 that has passed through the second roller 72 can be corrected by the ring 74 or the third roller 76, the conducting wires 12 can be evenly aligned.
さらに、導線１２にはテンショナ８２及び第１ローラ７０等により多少の曲がり癖が加わる場合があるが、本実施の形態に係る波形巻線形成方法によれば、導線１２の巻き付けを矢印Ａ２方向にのみ繰り返して行うことから導線１２の曲がり癖が一定であり、形成される波形形状における導線１２は均一に整列する。 Furthermore, the conductor 12 may be slightly bent due to the tensioner 82, the first roller 70, and the like. However, according to the corrugated winding forming method according to the present embodiment, the conductor 12 is wound in the arrow A2 direction. Since the process is repeated only, the bending curve of the conducting wire 12 is constant, and the conducting wires 12 in the corrugated shape to be formed are uniformly aligned.
本発明に係る波形巻線形成装置及び波形巻線形成方法は、上述の実施の形態に限らず、本発明の要旨を逸脱することなく、種々の構成乃至ステップを採り得ることはもちろんである。 The corrugated winding forming apparatus and corrugated winding forming method according to the present invention are not limited to the above-described embodiments, and it is needless to say that various configurations or steps can be adopted without departing from the gist of the present invention.
