駆動機構を含む駆動装置とからなる。 A toroidal winding machine that winds a wire around a toroidal core includes a core holding device that reciprocates the core around its axis, and a core holding device that intersects with the core and is introduced into the core and rotatably supported. It consists of a shuttle that stores the wire and then winds it around the core while unwinding it, and a drive device that includes a core holding device and a periodic drive mechanism for the shuttle.

と平行ではなく右側に傾いていた。 The conventional core holding device holds the core using three cylindrical rubber rollers (for example, two for driving and one for following) that are coaxially engaged and attached to the upper end of an upright shaft whose lower end is pivotally supported. It was configured to be pressed against the outer periphery from three sides. Since the shaft of the roller is in the shape of a cantilever, the shaft deflects outward when pressed against the core, and the roller tends to be weakly pressed against the upper periphery of the core and strongly pressed against the lower periphery of the core. In addition, the winding machine that is wound around the core (hereinafter, the winding machine in this state is referred to as the winding machine), for example, when the core is rotated clockwise and the shuttle passes through the core from top to bottom, It was tilted to the right instead of parallel to the axis of the core.

〔考案が解決しようとする問題点〕[Problem that the invention attempts to solve]

従来のコア保持装置ではローラがコアの下部周
縁により強く圧接し、極端な場合下部周縁だけに
圧接しており、そのために巻線のコア下部周縁側
がコアの回動方向（ここでは時計回り）に上部側
より大きくずらされてコア外周での巻線の傾きが
強められ巻線に乱れが生じ見映えが悪くなるとい
う問題があり、特に整列重ね巻きする場合、二層
目は一層目の巻線の終了点から始めてコアを一層
目と逆向き（ここでは反時計方向）に回動させる
ので、一層目巻線のコア下部周縁側がコア外周で
の巻線の傾きが減る方向に（下部側）よりずれて
一層目巻線のコア外周での傾きが一様でなくな
り、二層目の整列巻きが困難であるという問題が
あつた。 In conventional core holding devices, the rollers press more strongly against the lower periphery of the core, and in extreme cases, only the lower periphery, so that the lower periphery side of the core is rotated in the direction of rotation of the core (in this case, clockwise). There is a problem in that the windings are shifted far from the upper side and the windings are tilted at the outer periphery of the core, which causes the windings to become disordered and the appearance to be poor.Especially when aligning and overlapping windings, the second layer windings are closer to the first layer windings. Starting from the end of the wire, the core is rotated in the opposite direction to the first layer (counterclockwise in this case), so that the lower peripheral edge of the core of the first layer winding is rotated in the direction that reduces the inclination of the winding at the outer periphery of the core (lower There was a problem that the inclination of the first layer winding around the core periphery became uneven due to deviation from the side), making it difficult to wind the second layer in alignment.

As shown in the rotational cross-sectional view of the line, the cross-sectional shape is an inverted trapezoid, an inverted truncated cone, and the inclination of the circumferential surface (△θ)
is equal to or greater than the angle formed by the vertical line and a line connecting the fulcrums of the shafts 5 and 7 and the upper shaft end when the toroidal core 10 is held in pressure contact. A metal collar 8 is provided near the upper end of the shafts 5 and 7, and a collar plate 9 made of a hard resin material and having the same size as the collar 8 is fixed to the upper surface of the collar 8. Coaxial rollers 1, 2, and 3 are fixed on a collar plate 9. The collar plate 9 is provided to prevent damage to the windings, and the collar plate 9 may be omitted if the collar 8 is made of hard resin instead of metal.

て、巻線材の貯線・巻き付けが行われる。 As already explained, since the roller 3 is elastically supported, the core 10 can be freely rotated by pressing the rollers 1, 2, and 3 against the outer periphery of the toroidal core 10 from three sides as shown in FIG. is maintained. A shuttle 11 (part of which is shown by a chain line) is introduced into the central hole of the core 10 held in this manner, and the winding material is stored and wound.

る。 Since the core holding device has such a configuration, the pressure contact between the core 10 and the rollers 1, 2, and 3 is strong.
Even if the shaft 5.7 is deflected, the rollers 1, 2, 3
The outer periphery in contact with the core 10 is either vertical or inclined so that it contacts only the upper periphery of the core 10 as shown in FIG. The winding is on the outer peripheral surface of the core.
In the rotating direction of the rollers 1, 2, and 3 (clockwise here), either the winding inclination by the shuttle 11 remains unchanged, or only the upper peripheral edge of the core shifts and the inclination of the winding decreases. There is less disorder in the winding than in the past, and it is easier to align and overlap winding.
