本考案は、トロイダル巻線機におけるコア保持
装置に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a core holding device in a toroidal winding machine.
トロイダルコアに巻線機を巻き回すトロイダル

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.

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.

The shaft 5 can be moved in an arc shape as shown by the arrow with a handle (not shown) centered on two points, and the lower end of the shaft 5 is pivotally supported on the other end side of the bed plate 4.
It has a built-in mechanism to rotate it. The lower end of the shaft 7 of the roller 3 is supported by a base plate 6 which is supported by a pair of guide plates (only one is shown) and can move linearly as shown by the arrow. A spring is built in to urge the base plate 6 in the direction of the drawing arrow.

ればつば板9を省いてもよい。 The rollers 1, 2, and 3 are shown in FIG. 2 as shown in FIG.
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.
既に説明したようにローラ3が弾発的に支持さ

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.
以上に述べたように本考案によれば、従来より
