Next, a description will be given of a method of winding a filament according to the present embodiment using such a filament winding device.

In this embodiment, when the wire is aligned and wound around the outer circumference of the winding drum 6a of the bobbin 6 via the guide sheaves 4, 5 incorporated in the apparatus frame 3, the linear body 1 is wound around the outer circumference of the winding drum 6a of the bobbin 6. Is wound by aligned winding while traversing so that the winding position is sequentially changed in the axial direction of the winding drum 6a. When the filament 1 is wound around the flange 6b of the bobbin 6, the traverse direction is reversed. The filament 1 is wound around the outer periphery of the strand winding layer 17 by aligned winding.

At this time, in this embodiment, as shown in FIG. 3, the traverse is performed by using one of the pair of pressing roller units 11 of the first filament winding guide mechanism 9. Winding is performed while restricting the winding position of the filament 1 on the winding drum 6a up to the side of the flange 6b before reversing the direction. In other words, the winding position of the filament 1 on the winding drum 6a is pressed against the outer periphery of the winding drum 6a by the pressing roller portion 11a of the pressing roller unit 11 up to the side of the flange 6b before the reversal of the traverse direction, and has already been wound. Winding is performed while restraining the side surface of the filament 1 of the last turn of the same layer by the flange roller portion 11b so as to abut when the filament 1 slides in the direction of the approaching flange 6b. . In this way, winding can be performed at a predetermined pitch without leaving a large gap between turns of the linear body 1 adjacent to the outer periphery of the winding drum 6a except for the sides of the flange 6b.

When the filament 1 is wound around the flange 6b, the second filament winding guide mechanism 10, which has been waiting at a position radially away from the winding drum 6a, is moved to the position shown in FIG. As shown in the figure, the outer periphery of the wrapping layer 17 is pressed by the front end surface 18a of the first holding block 18 by moving forward to the winding drum 6a side.

In this state, the one pressing roller unit 11 described above retreats in the radial direction from the winding drum 6a.

On the side of the brim 6b, the first layer of the striated body winding layer 17
When the winding of the filament 1 of the first turn of the second layer is performed on the first layer, the first holding block 18 urges the spring 23 onto the filament 1 of the first turn of the second layer. Figure 4 against
Ride as shown in (B). First presser block 1
8 rises and retreats from the winding drum 6a, the second holding block 19 remains as it is as shown in FIG.
It comes into contact with the side surface of the striatum 1 of the first turn of the layer.

Further, the first holding block 18 is
a in the direction away from the first holding block 1
The operator 18c protruding from the side surface of the arm 8 also moves up and presses the traverse inversion signal sending means 20 composed of a direct acting potentiometer, and the traverse inversion signal sending means 20 sends out the traverse inversion signal. . This traverse inversion signal is applied to the traverse device 7 so that the traverse direction of the bobbin 6 is inverted.

When the traverse direction of the bobbin 6 is reversed and the bobbin 6 moves in the direction shown by the arrow in FIG. 4C, the first holding block 18 moves to the first layer as shown in FIG. The top surface 18a of the first pressing block 18 is pressed on the outer periphery of the first layer winding layer 17 on the top surface 18a of the first layer, and the second layer turns on the side surface 18b of the first pressing block 18. Is brought into contact with the side surface of the striatum 1 and pressed.

In this state, the other pressing roller unit 11 of the pair of pressing roller units 11 of the first filament winding guide mechanism 9 advances to the winding drum 6b side, and Pressing roller section 11 of roller unit 11
a presses the outer periphery of the second-layer wire winding layer 17, and the flange roller portion 11 b holds the side surface of the wire 1 of the last turn of the second-layer wire winding layer 17 as a wire. When the body 1 slides in the direction of the adjacent flange 6b, the body 1 comes into contact with the body 1 and is wound while being restrained.

In such a state, the second filament winding guide mechanism 10 retreats so that the winding drum 6a is separated in the radial direction, and the first filament winding guide mechanism 9 moves the filament 1 around. Winding is performed while restricting the winding position.

The restraining of the winding position of the filament 1 by the first filament winding guide mechanism 9 and the second filament winding guide mechanism 10 is repeated, and a full winding state is obtained. Then the winding is finished.

As described above, when the filament 1 is wound up in the middle of the winding drum 6a of the bobbin 6, and when the filament 1 is wound around the flanges 6b at both ends of the bobbin 6, each of the filaments 1 is By constraining the winding position, it is possible to orderly wind the filament 1 at a predetermined pitch in the middle of the winding drum 6a of the bobbin 6 and at the flanges 6b at both ends of the bobbin 6. In particular, bobbin 6
During the winding of the filament 1 in the middle of the winding drum 6a and the winding of the filament 1 near the flanges 6b at both ends of the bobbin 6, the filament 1 is pressed against the outer periphery of the winding drum 6a and wound. When the winding pitch of the filament 1 at the turn to be attached is shifted, winding is performed while restraining the side surface of the filament 1 so as to return to a normal position. In addition, even if the winding pitch of the striated body 1 is deviated at the flanges 6b at both ends of the bobbin 6, this is corrected so that the aligned windings can be arranged at a predetermined pitch without leaving a large gap between adjacent striated body turns. Can be done.

Further, the first striated body winding guide mechanism 9 and the second striated body winding guide mechanism 10 are used, and the second striated body winding guide mechanism 10 is provided with a traverse inversion signal transmitting means 20. When winding the filament 1 on the way of the winding drum 6a of the bobbin 6 and winding of the filament 1 on the flange 6b at both ends of the bobbin 6, Striatum 1
When the winding pitch of the filament 1 of the turn to be pressed and wound is shifted, the winding can be performed while restraining the side surface of the filament 1 to return to the normal position, and the bobbin 6 is wound. Even if the winding pitch of the filament 1 is deviated in the middle of the trunk 6a or at the flange 6b at both ends of the bobbin 6, this is corrected and the predetermined pitch is maintained without leaving a large gap between adjacent filament turns. The alignment winding can be performed orderly.

As shown in FIG. 5A, when the shaft 15 of the pressing roller unit 11 is fixed to the arm 13 of the roller urging means 12 for transmitting the pressing force, the pressing roller unit 11 is attached to the flange 6b. At this time, since the flange 6b is not perpendicular to the winding drum 6a at this time, the flange 6b swings, and the pressing force in the direction of pressing the pressing roller unit 11 against the flange 6b is reduced. When it acts, the connection between the shaft 15 of the pressing roller unit 11 and the arm 13 of the roller urging means 12 may be damaged by the pressure.
