The bobbin 12 is driven by a traverse method and rotates while moving in the axial direction, so that the fixed guide roller 34 is rotated. The supported square wire W is drawn out, and the first layer is aligned and wound (leaded) in a string winding shape. When the bobbin 12 has been wound from one end side to the other end side in the axial direction, the second layer reverses the winding direction and is again aligned and wound (reverse lead winding) into a string winding shape. Accordingly, the second layer can be stacked on the first layer while intersecting every one turn (360 degrees per rotation) without changing the square line W (transfer portion C1). As shown in FIG. 2, the substrate 35 to which the guide roller 34 is fixed is supported in a floating manner, and by swinging the head following the winding direction of the winding C, a stable square line W can be pulled out. To.

  At this time, as shown in the drawing, the winding direction of the square line W is inclined with respect to the direction perpendicular to the axis, so that a gap G is formed between the end of the bobbin 12 and the winding C. When starting to wind one turn of the second layer over the last turn of the first layer, if a square line W falls into this gap G, there is a step in the winding C at the transfer portion C1 from the first layer to the second layer. Formed or loosened easily. Therefore, in the present invention, the fixed guide members 61 and 71 and the movable guide members 63 and 73 arranged at both ends of the bobbin 12 with the spiral convex portions (hereinafter referred to as pseudo mountains) along the gap as guide portions. , 64, 74, and multi-winding while guiding so as not to cause bending or bending of the square line W due to climbing upon transfer. The details will be described next.

  As shown in FIG. 8A, the inner fixed guide members 61 and 71 are thick cylindrical bodies, and the clamp shaft 13 is inserted and fixed in the cylindrical hole so as to rotate integrally (see FIG. 5). On the front end side (upper surface in the drawing) of the inner fixed guide members 61 and 71, pseudo mountains 61a and 71a serving as guide portions are formed to protrude. The pseudo mountains 61a and 71a are substantially C-shaped spiral convex portions along the outer peripheral edges of the inner fixed guide members 61 and 71, and the spiral shape (projection height, spiral angle) is the size of the square line W or the winding C.

The leg portions 63b and 73b of the inner movable guide members 63 and 73 have an end protruding inward in an L shape, and elongated holes 63c and 73c are formed in the two opposing legs. The leg portions 64b and 74b of the outer movable guide members 64 and 74 have an end portion protruding outward in an L shape, and elongated holes 64c and 74c are formed in two opposing legs.

  The pseudo mountains 63a and 73a of the inner movable guide members 63 and 73 and the pseudo mountains 64a and 74a of the outer movable guide members 64 and 74 are substantially C-shaped along the outer peripheral edges of the guide members 63, 73, 64, and 74, respectively. It is a spiral convex part, and the spiral shape (projection height, spiral angle) is set according to the size of the square line W and the winding angle of the winding C. In FIG. 5, the inner movable guide members 63 and 73 and the outer movable guide members 64 and 74 are arranged concentrically so that the long holes 63c and 73c communicate with the long holes 64c and 74c. The elongated members 63c and 73c and the elongated holes 64c and 74c are inserted with shaft-like members 67 and 77 attached to the outer periphery of the clamp shaft 13 so as to restrict the movement range in the axial direction and to be positioned in the rotational direction. Yes.

  The rotation direction and amount of rotation of the rotation flange 65 of the inner movable guide member 63 and the rotation flange 66 of the outer movable guide member 64 are independently controlled by the drive unit 68. Similarly, the rotation direction and amount of rotation of the rotation flange 75 of the inner movable guide member 73 and the rotation flange 76 of the outer movable guide member 74 are independently controlled by the drive unit 78. These drive units 68 and 78 include, for example, cylinder actuators and the like, and are controlled together with the motor M of the rotary spline shaft 11 by a control device (not shown). Specifically, in conjunction with the rotation of the clamp shaft 13 and the winding of the square line W by the axial movement, the corresponding movable guide members 63, 64, 73, 74 are transferred before the layer is transferred at the end of the bobbin 12. Can be controlled to advance to a predetermined position and retract after the end of winding.

  Referring to FIG. 9, the movable guide members 63, 64, 73, and 74 are formed when a wire W having a four-layer structure is formed by winding a rectangular wire W around the bobbin 12 of the winding unit 1 using the winding device having the above configuration.

As shown in the figure, in order to transfer from the 9th turn of the first layer to the 1st turn of the second layer, a pseudo mountain 61a of the inner fixed guide member 61 is arranged in accordance with the gap generated on the inner periphery of the second layer. . Thereby, it can pass over smoothly, without the square W of the 2nd layer which expands diameter falling. Further, in order to reverse the inclination direction of the winding C from the first layer to the second layer, the pseudo mountain 63a of the inner movable guide member 63 is arranged in accordance with the gap generated on the outer periphery of the first layer. The winding direction can be adjusted by guiding the square line W of the second layer.

  Similarly, in FIG. 9A, the pseudo mountain 73a of the inner movable guide member 73 and the pseudo mountain 74a of the inner movable guide member 74 are sequentially moved by the drive unit 78 in the transfer portion from the second layer to the third layer. Further, in the transfer portion from the third layer to the fourth layer, the pseudo mountain 64a of the outer movable guide member 64 is moved by the drive unit 68 and wound up to nine turns of the fourth layer, and the same effect is obtained. can get.

  In addition, in order to prevent the level difference due to the drop of the corner line W or the climbing, it is sufficient that a pseudo mountain is formed at least at the transfer portion. For this reason, in this embodiment, in order to simplify the device configuration, the fourth layer of the outermost layer is not provided with a pseudo mountain for guidance, but a movable type in which a pseudo mountain is provided in a portion facing the illustrated gap. It can also be used as a guide member.

  In the above embodiment, the winding C has a four-layer winding structure, but the number of turns and the number of layers can be arbitrarily set.

  According to the winding device and the winding method of the present invention, a multi-layer aligned winding is provided without causing deformation or damage by stably supplying the square wire in the winding direction while reciprocating the winding portion of the square wire. Therefore, downsizing and high performance are possible.
