Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、電磁機器等に使われるコイルを巻回成形する
際に用いるコイル巻枠に関する。TECHNICAL FIELD The present invention relates to a coil winding frame used when winding forming a coil used in an electromagnetic device or the like.
巻枠を用いてコイルを巻回成形する場合、巻枠とコイル
を互いに一体化させて製品にする場合はコイルを巻枠か
ら取外す必要はないが、いわゆる素巻きコイルを作る場
合には、コイルの成形後に巻枠からコイルを取外す必要
がある。このためこの種の巻枠は特殊な構造のものが使
用されている。When winding a coil using a reel, it is not necessary to remove the coil from the reel when the reel and the coil are integrated with each other to form a product. It is necessary to remove the coil from the bobbin after molding. For this reason, this type of reel has a special structure.

し時にコイルを掛けるコイル案内棒を放射方向に移動可
能に設けることにより、コイル巻型を分解することなく
コイル完成品を取外せる構造のものが知られている。For example, like the coil winding frame seen in Japanese Examined Patent Publication No. Sho 55-26111, a plurality of divided coil winding dies are provided by an arm so that they can be expanded and contracted in the radial direction, and a coil guide rod for hanging the coil when removing the coil is provided. There is known a structure in which a coil finished product can be removed without disassembling the coil winding form by movably providing the coil winding form.
しかしながら上記先行技術はコイルを取出すための巻枠
構造がきわめて複雑かつ大掛りであり、装置と製品のコ
スト高を招くばかりでなく、構造が複雑な分だけ作業の
段取りやメンテナンスに手間がかかる。However, in the above-mentioned prior art, the winding frame structure for taking out the coil is extremely complicated and large in size, which not only increases the cost of the device and the product, but also requires complicated work setup and maintenance due to the complicated structure.

徴とする。INDUSTRIAL APPLICABILITY The present invention is applied to a coil winding frame provided with a winding drum having four corner portions in the circumferential direction on a surface around which a coil is wound.
In the present invention, the winding drum is divided into four winding drum components for each of the corner portions. A spring for urging adjacent winding drum constituent pieces in a direction to draw each other, and a holding means capable of being engaged with and disengaged from the winding drum constituent pieces and capable of supporting the winding drum constituent pieces in a state of being spread to a predetermined width. Is provided.

に取出すことができる。When the coil is wound and formed, each winding drum constituent piece is fixed in a state of being expanded to a predetermined width by the holding means. When a certain amount of coil is wound around the winding drum and then the winding drum component pieces are released from the holding means, adjacent winding drum component pieces are attracted to each other by a spring, thereby reducing the outer diameter of the winding drum. . Therefore, the coil after the winding molding can be easily taken out from the winding drum.

A concave portion 47 is formed. The convex portion 46 and the concave portion 47 are provided at positions where they are fitted to each other when the winding drum component pieces 11 to 14 are expanded to a predetermined width. Therefore, the convex portion 46 and the concave portion 4
7 constitutes a part of the holding means 40. In addition, the convex portion 46 is provided on the winding drum component pieces 11 to 14, and the concave portion 47 is formed on the flange plate 4.
It may be provided in the.

て形成されている。Further, on the edges of the flange plates 3 and 4, recesses 54 and 55 having a length reaching the outer peripheral surface (coil winding surface) of the winding drum 2 are formed. As shown in FIG. 2, in one of the recesses 54, a winding support groove 57 having a substantially V-shaped cross section is formed at a corner portion extending from the side wall surface 54a of the recess 54 to the surface 54b on the winding drum 2 side. . The winding support groove 57 prevents the lead-in portion of the winding located in the lowermost layer from moving in the radial direction when the coil is wound. Therefore, this winding support groove 57
Are formed along the outer peripheral surface of the winding drum 2, that is, the surface around which the coil is wound.
次に上記構成のコイル巻枠１の作用につき説明する。Next, the operation of the coil winding frame 1 having the above structure will be described.

フランジ板３，４と巻胴２を一体化させる。The flange plates 3 and 4 are assembled to the winding drum 2, and the shaft 31 is inserted into the shaft insertion hole 19 and the through holes 28 and 29. At this time, the winding drum component pieces 11 to 14 have the tapered pressing portion 34 and the pressing member 50.
The winding drum constituent pieces 11 to 14 are fixed by being pushed to a predetermined width by the convex portion 46 and fitted into the concave portion 47. In this state, the nut 39 is screwed onto the male screw 32 and tightened to integrate the flange plates 3 and 4 and the winding drum 2 as shown in FIG.

ながら順次重ねられてゆく。Then, the winding support groove 57 of the flange plate 4 is hooked with the winding introduction portion of the coil, and then the winding frame 1 is rotated around the shaft 31, and a winding (not shown) is supplied. Wind the winding around the winding drum 2. At this time, the lowermost winding is closely wound while keeping a predetermined pitch by the grooves 9 formed in the corner portions 5 to 8. Then, the windings of the second and subsequent layers are sequentially stacked on top of each other while shifting their positions alternately in a so-called bale stacking manner.

まり、成形後のコイルを容易に取出すことができる。When the predetermined number of turns has been reached, the rotation of the reel 1 is stopped, the nut 39 is removed, the flange plate 4 is removed from the reel 2, and the shaft 31 is moved in the pull-out direction. As a result, the one winding drum component 11 or 12 is attracted to each other by the pulling force of the spring 16, and the other winding drum component 13 or 14 is also attracted to each other by the spring 17. Moreover, since the winding drum component pieces 11 to 14 are movable only in the longitudinal direction of the elongated hole 44, the winding drum component pieces 11, 13 and 12, 14 which are not connected by the springs 16 and 17 are also close to each other. Move to. In this way, the outer shape of the winding drum 2 is reduced, and the coil after molding can be easily taken out.
コイルを取出したのちは、再び巻胴２とフランジ板３，
４および軸３１を一体に組付けることにより、前記と同
様にコイルを成形することができる。After taking out the coil, the winding drum 2 and the flange plate 3,
By assembling the 4 and the shaft 31 integrally, a coil can be formed in the same manner as described above.

コイルを同時に巻回成形できるようにしてもよい。The holding means 40 does not necessarily have to be provided on the flange plates 3 and 4. For example, a structure for holding the winding drum component pieces 11 to 14 in an unfolded state by attaching a holding component formed separately from the flange plates 3 and 4 to the end surfaces of the winding drum component pieces 11 to 14 and the like. But it's okay. Further, a plurality of sets of winding frames 1 may be arranged and attached in the axial direction of the shaft 31 so that a plurality of coils can be simultaneously wound and formed.
