本発明は、コイル巻線方法及び装置の改良に関するものである。   The present invention relates to an improved coil winding method and apparatus.

断面が四角形の平角線を巻回して形成される渦巻き状コイルは、巻回方向に隣接する線材の面同士が接触し、線材の占積率（密度）を高められることが知られている。   It is known that a spiral coil formed by winding a rectangular wire having a quadrangular cross section can make the space factor (density) of the wire rods higher by contacting the surfaces of the wire rods adjacent to each other in the winding direction.

従来、特許文献１には、図１０に示すように、平角線を渦巻き状に巻回した第一、第二コイル１００ａ，１００ｂを有する二列渦巻き（外外巻き）コイル１００を形成するコイル製造装置が開示されている。   Conventionally, in Patent Document 1, as shown in FIG. 10, a coil manufacturing method for forming a two-row spiral (outer and outer winding) coil 100 having first and second coils 100 a and 100 b in which a rectangular wire is spirally wound. An apparatus is disclosed.

この装置は、中央の巻取り部材を挟んで第一、第二挟み部材が同軸上に設けられる。線材源から供給される平角線の線材を予め蓄線リールに巻き取り、この蓄線リールを第二挟み部材に取り付、線材の中程１０４を巻取り部材のスリットに通して保持する。そして、中央の巻取り部材と第一挟み部材が同期回転することにより線材源から供給される線材を巻取り部材と第一挟み部材の間に渦巻き状に巻回する一方、第二挟み部材が２倍の速度で回転することにより蓄線リールから供給される線材を巻取り部材と第二挟み部材の間に渦巻き状に巻き取り、第一、第二コイル１００ａ，１００ｂを同時に巻回するようになっている。   In this device, the first and second pinching members are provided coaxially with the central winding member interposed therebetween. A rectangular wire supplied from a wire source is wound in advance on a storage reel, the storage reel is attached to a second pinching member, and the middle 104 of the wire is passed through a slit in the winding member. Then, the central winding member and the first sandwiching member rotate synchronously to wind the wire supplied from the wire source in a spiral between the winding member and the first sandwiching member, while the second sandwiching member By rotating at a double speed, the wire supplied from the storage reel is wound in a spiral between the winding member and the second pinching member, and the first and second coils 100a and 100b are wound simultaneously. It has become.

第一、第二コイル１００ａ，１００ｂの巻芯部において第一、第二コイル１００ａ，１００ｂの始点となる部位には第一、第二巻付け案内部材がそれぞれ突出して設けられており、線材が第一、第二巻付け案内部材に沿って非円形に巻回される。
特開平４−１９２５９３号公報 In the core portions of the first and second coils 100a and 100b, first and second winding guide members are provided so as to project at the starting points of the first and second coils 100a and 100b, respectively.

しかしながら、このような従来のコイル巻線方法にあっては、第一、第二コイル１００ａ，１００ｂが中央の巻取り部材を挟んで巻回されるため、第一、第二コイル１００ａ，１００ｂの間に間隙ができ、線材の占積率を高められないという問題点があった。   However, in such a conventional coil winding method, since the first and second coils 100a and 100b are wound around the central winding member, the first and second coils 100a and 100b There was a problem that a gap was formed between them and the space factor of the wire could not be increased.

また、第一、第二コイル１００ａ，１００ｂは巻芯部に設けられる第一、第二巻付け案内部材に沿って巻回されると、第一、第二コイル１００ａ，１００ｂが非円形に形成されるため、第一、第二コイル１００ａ，１００ｂの内外周部に間隙ができ、線材の占積率を高められないという問題点があった。   Further, when the first and second coils 100a and 100b are wound along the first and second winding guide members provided in the core portion, the first and second coils 100a and 100b are formed in a non-circular shape. Therefore, there is a problem that gaps are formed in the inner and outer peripheral portions of the first and second coils 100a and 100b, and the space factor of the wire cannot be increased.

本発明は上記の問題点に鑑みてなされたものであり、線材の占積率を高められるコイル巻線方法及び装置を提供することを目的とする。   This invention is made | formed in view of said problem, and it aims at providing the coil winding method and apparatus which can raise the space factor of a wire.

Since the forming rotator 62 is rotationally driven in one direction to form the first bent portion 108 in the interposed state, the forming rotator 62 is rotationally driven in the other direction to form the second bent portion 109. It becomes possible to form the stepped portion 107 bent in a crank shape at a predetermined position with respect to the wire 101 with high accuracy, and the gap between each stepped portion 107 is reduced, so that the wire 101 in the first coil 102 Increases the space factor.
