【発明の属する技術分野】
この発明は、供給される電磁ワイヤを、フライヤの旋回動作とガイド部材の案内動作により、積層鉄心のスロットへ案内、巻回して巻線を行う巻線装置に関するものである。
【０００２】
【従来の技術】
図７は例えば特開昭６１−３０９４１号公報等に開示されるこの種従来の巻線装置の要部の構成を示す断面図である。
従来の巻線装置は、図に示すように積層鉄心１の積層方向端部にガイド部材２が配置され、供給される電磁ワイヤ３はフライヤ（図示せず）の旋回動作、およびガイド部材２の案内動作により積層鉄心１の磁極テイース間に形成されるスロット内へ所望の回数だけ巻回される。そして、ガイド部材２は積層鉄心１の半径方向（図中矢印Ｙで示す方向）に、順次所定の間隔で図中破線で示すように移動し、その都度電磁ワイヤ３が所望の回数ずつ巻回されて巻線が行われる。
【０００３】
【発明が解決しようとする課題】
従来の巻線装置は以上のように巻線がなされ、巻線のスロット内における占積率を向上させるために、巻線の前後にガイド部材２により巻線に成形を与え、巻線をスロットの奥部に押し込む方法が用いられているが、積層鉄心１の積層厚み（図中Ｗで示す）のばらつきにより、ガイド部材２と積層鉄心１の端面との間に隙間（図中Ｇで示す）が生じる場合があり、この隙間Ｇに電磁ワイヤ３が入り込み、成形動作が有効に行われないばかりか、電磁ワイヤ３が損傷する恐れがある等の問題点がある。
【０００４】
このため、図示はしないが特開昭６３−２５７４４０号公報では、ガイド部材を積層鉄心の積層方向に移動可能とし、積層鉄心の端面との間に所定の隙間ができるように配置することが開示されているが、巻線の成形時にはかなりの大きさの力がかかるため、電磁ワイヤが強引に隙間内に入り込む恐れもあり、電磁ワイヤが損傷するのを確実に防止することができないという問題点があった。
【０００５】
この発明は上記のような問題点を解消するためになされたもので、電磁ワイヤを損傷させることなく、巻線の占積率の向上を図ることが可能な巻線装置を提供することを目的とするものである。
【０００６】
【課題を解決するための手段】
この発明の請求項１に係る巻線装置は、供給される電磁ワイヤを、フライヤの旋回動作とガイド部材の案内動作により、積層鉄心の磁極テイース間に形成されるスロットへ案内、巻回して巻線を行う巻線装置において、

【０００７】
又、この発明の請求項２に係る巻線装置は、積層鉄心の積層方向に所定の間隔を介した外方に、周方向に所定の間隔を介して積層鉄心の半径方向に移動可能に一対ずつ配置され、半径方向内方に所定の力が付勢されたカム部材と、カム部材を解放可能に所定の位置で保持する保持部材と、積層鉄心の積層方向に回動可能に支承され、積層方向に傾斜を有しカム部材が嵌合して摺動可能なカム溝を有する回動部材と、先端に押圧面を有し回動部材上に回動方向の動きが拘束されて配置され、積層鉄心の積層方向両端側を積層鉄心の半径方向外方に、所定の間隔で順次移動可能なガイド部材と、旋回することによりガイド部材を介して積層鉄心の磁極テイース間に形成されるスロットへ、供給される電磁ワイヤを巻回するフライヤとを備え、カム部材の保持部材による保持を解放することにより、付勢された所定の力で回動部材を回動させ、ガイド部材の押圧面を磁極テイースの端面に押圧するようにしたものである。
【０００８】
又、この発明の請求項３に係る巻線装置は、請求項１または２において、ガイド部材の磁極テイースの端面を押圧する押圧面は、磁極テイースの高さ方向両側に磁極テイースの端面から漸次遠ざかるように湾曲して、磁極テイースの端面との間に隙間が形成されるとともに、巻線が行われる側の端部の隙間は、電磁ワイヤの線径の１／２以下の寸法に形成されるものである。
【０００９】
又、この発明の請求項４に係る巻線装置は、請求項１ないし３のいずれかにおいて、ガイド部材には、磁極テイースの端面を押圧したままの状態を維持するロック機構を具備するものである。
【００１０】
又、この発明の請求項５に係る巻線装置は、請求項１ないし３のいずれかにおいて、ガイド部材が、電磁ワイヤを巻回する動作の前後に、磁極テイースの端面を押圧したままの状態で、積層鉄心の半径方向内方に所定の距離だけ移動するものである。
【００１１】
【発明の実施の形態】
以下、この発明の実施の形態を図に基づいて説明する。
実施の形態１．
図１はこの発明の実施の形態１における巻線装置の構成を示し、（Ａ）は正面図、（Ｂ）は側面図、図２は図１における巻線装置の要部の動作停止時における状態を示す断面図、図３は図１における巻線装置の要部の動作開始時における状態を示す断面図、図４は図１におけるガイド部材の押圧面の構成を示す詳細図、図５は図１におけるガイド部材の成形動作を示す図、図６はこの発明の実施の形態１における巻線装置の図１とは異なる構成を示し、（Ａ）は正面図、（Ｂ）は側面図である。
【００１２】
図において、１１は板状磁性部材を積層して形成された積層鉄心で、周方向に所定の間隔を介して磁極テイース１１ａが設けられ、これら各磁極テイース１１ａ間にスロット１１ｂがそれぞれ形成されている。１２は積層鉄心１１の積層方向の両端外方に、周方向に所定の間隔を介し積層鉄心１１の半径方向に移動可能に一枚ずつ配置されたカム部材、１３はこれら各カム部材１２に半径方向内方（図中矢印Ａで示す）に向かって所定の力を付勢する複数のバネ部材、１４はこれら各バネ部材１３が圧縮された状態の位置でカム部材１２を保持する保持部材で、半径方向内方（図中矢印Ｂで示す）に移動することにより、カム部材１２を開放可能に配設されている。
【００１３】
１５は図中矢印Ｃ１、Ｃ２で示すように回動可能に支承される回動部材で、積層鉄心１１の積層方向に傾斜を有し、カム部材１２が嵌合して摺動可能なカム溝１５ａを有している。１６は回動部材１５上に回動方向の動きが拘束されて配置され、回動部材１５上を図示しない駆動機構により駆動され、積層鉄心１１の半径方向（図中矢印Ｄ１、Ｄ２で示す）に移動可能なガイド部材で、先端の積層鉄心１１の端面と対応する側に押圧面１６ａが、積層鉄心１１の軸心と対応する側に成形面１６ｂが、又、この成形面１６ｂの外方に連なって傾斜した案内面１６ｃがそれぞれ形成されており、押圧面１６ａは図４に矢印Ｅで示すように、磁極テイース１１ａの高さ方向両側に、磁極テイース１１ａの端面から遠ざかるように湾曲して、磁極テイース１１ａの端面との間に隙間Ｇが形成され、この隙間Ｇは電磁ワイヤ１８の線径の１／２以下の寸法に形成されている。そして、このガイド部材１６は例えば図１（Ｂ）に示すように所定の間隔を介した両スロット１１ｂに、それぞれ対応するように配設されている。１７は旋回することにより供給される電磁ワイヤ１８を、ガイド部材１６を介して積層鉄心１１の所定のスロット１１ｂ内へ巻回するフライヤである。
【００１４】
次に、上記のように構成される実施の形態１における巻線装置の動作について図に基づき説明する。
まず、常時は図２に示すように、保持部材１４によりカム部材１２が保持されているため、回動部材１５は矢印Ｃ１側に回動された状態で、又、回動部材１５上のガイド部材１６は、矢印Ｄ１側に移動した所定の位置で、押圧面１６ａが磁極テイース１１ａの端面から離れた状態でそれぞれ待機している。
次いで、巻回が開始されると、図３に示すように保持部材１４が図中矢印Ｂで示す方向に移動し、これに伴ってカム部材１２がバネ部材１３の付勢力によって図中矢印Ａで示す方向に、回動部材１５のカム溝１５ａ内を移動する。
【００１５】
すると、回動部材１５はカム溝１５ａが積層鉄心１１の積層方向に傾斜を有しているため、図中矢印Ｃ２で示す方向に回動し、この回動によりガイド部材１６の押圧面１６ａが磁極テイース１１ａの端面を押圧する。この状態でフライヤ１７を旋回させると、供給される電磁ワイヤ１８は図１に示すように、ガイド部材１６の案内面１６ｃを図中矢印Ｆで示すように案内され、所定の間隔を介した両スロット１１ｂ内へ順次巻回される。
【００１６】
そして、所定の回数だけ巻回が終了すると、積層鉄心１１が回転して次の磁極テイース１１ａが対応する位置に配置され、上記と同様の動作が繰り返されることにより所定の間隔を介した次の両スロット１１ｂ内に順次巻回され、円周上の全てのスロット１１ｂ内の巻回が終了すると、ガイド部材１６は図示しない駆動機構により、図中矢印Ｄ２で示す方向に順次所定の間隔で移動し、その間それぞれ上記のような動作が繰り返されて巻線が完了するが、ガイド部材１６は電磁ワイヤを巻回する動作の前後に、図５（Ｂ）に示すように、図中矢印Ｈで示すように磁極テイース１１ａの端面を押圧したままの状態で、図中矢印Ｉで示すように上記矢印Ｄ２で示す方向とは逆方向に所定の距離だけ移動する。この移動により電磁ワイヤ１８は図５（Ａ）に示す状態から、図５（Ｂ）に示すように成形面１６ｂによりスロット１１ｂの底部側に押しやられて成形がなされる。
【００１７】
このように上記実施の形態１によれば、巻線の巻回時に電磁ワイヤ１８を案内するガイド部材１６の押圧面１６ａで、磁極テイース１１ａの端面を押圧するようにしているので、ガイド部材１６と磁極テイース１１ａの端面との間に、電磁ワイヤ１８が入り込むこともなくなり、電磁ワイヤ１８を損傷させることなく、巻線の占積率の向上を図ることが可能になる。又、カム部材１２とこのカム部材１２に嵌合可能なカム溝１５ａを有する回動部材の動作により、ガイド部材１６の押圧面１６ａを磁極テイース１１ａの端面に押圧するようにしているので、簡単な構成で確実に、電磁ワイヤ１８を損傷させることなく、巻線の占積率の向上を図ることができる。
【００１８】
又、ガイド部材１６の押圧面１６ａを湾曲させて、磁極テイース１１ａの端面との間に隙間を形成し、巻線が行われる側の端面の隙間Ｇを電磁ワイヤ１８の線径の１／２以下の寸法にしたので、電磁ワイヤ１８を損傷させることがないことは勿論、磁極テイース１１ａの端面を傷つけることなく押圧することが可能になる。又、電磁ワイヤ１８を巻回する動作の前後に、ガイド部材１６を磁極テイース１１ａの端面を押圧したままの状態で、積層鉄心１１の半径方向内方に移動させて成形動作を行うようにしているので、さらに巻線の占積率を向上させることが可能になる。
【００１９】
なお、上記構成では述べなかったが、ガイド部材１６の押圧面１６ａで磁極テイース１１ａの端面を押圧したままの状態を、維持するロック機構を具備することにより、信頼性の向上を図ることが可能になる。
又、上記構成では巻線方式が分布巻の場合について説明したが、これに限定されるものではなく、図６に示すように積層鉄心１９の磁極テイース１９ａに、電磁ワイヤ１８を集中巻する巻線方式の場合に適用しても同様の効果を発揮し得ることは言うまでもない。
【００２０】
【発明の効果】
以上のように、この発明の請求項１によれば、供給される電磁ワイヤを、フライヤの旋回動作とガイド部材の案内動作により、積層鉄心の磁極テイース間に形成されるスロットへ案内、巻回して巻線を行う巻線装置において、

【００２２】
又、この発明の請求項３によれば、請求項１または２において、ガイド部材の磁極テイースの端面を押圧する押圧面は、磁極テイースの高さ方向両側に磁極テイースの端面から漸次遠ざかるように湾曲して、磁極テイースの端面との間に隙間が形成されるとともに、巻線が行われる側の端部の隙間は、電磁ワイヤの線径の１／２以下の寸法に形成したので、電磁ワイヤを損傷させることがないことは勿論、磁極テイースの端面を傷つけることなく、巻線の占積率の向上を図ることが可能な巻線装置を提供することができる。
