Description

Detailed Description of the Invention 3. Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a winding device for a toroidal core. The present invention relates to a toroidal core winding device suitable for performing toroidal winding.

[Conventional technology]

A conventional wire winding device, as described in Japanese Patent Application Laid-open No. 60-91614, includes a pair of wire feeding devices disposed between a holder that holds a body to be wound and is rotationally driven;
A pair of wire suction devices are disposed, and the wire feeding device includes a clamping portion that slidably clamps the wire to be wound around the wire to be wound, and the wire is directed toward the wire to be wound. The wire suction device is provided with a feeding mechanism, and is driven in a direction in which it rotates around a direction in which it adheres to the holder and a direction perpendicular to this direction, and the wire suction device is driven in a direction in which it approaches and separates from the holder. At the same time, it is possible to suction the wire sent out from the above-mentioned feeding mechanism to give tension to the wire, and the wire is automatically wound around the body to be wound by the combination of the functions of the wire feeding device and the wire suction device. A new system is being implemented that will allow people to wear their clothes.

[Problem that the invention seeks to solve]

In the conventional technique, since it is necessary to install a wire feeding device and a feeding mechanism, the structure is complicated and the work is troublesome.

Furthermore, since the wire must be gripped and changed, it takes time to change the grip, so there is a limit to how much work time can be shortened.

SUMMARY OF THE INVENTION An object of the present invention is to provide a toroidal core winding device that solves the problems of the conventional technology, has a simple configuration, shortens working time, and improves the reliability of winding work. It is in.

[Means for solving problems]

The purpose is to provide an annular wire guide, a circular slit formed adjacent to the inner end of the wire guide, a roller disposed over the wire guide for transporting the wire through the wire guide, This is achieved by providing a mechanism for holding a core that is disposed in a part of the guide and has a core window connected to the line guide, and a movable line guide mechanism that moves the line guide toward and away from the slit.

[Effect]

In the present invention, when passing a wire through the core window, the wire guide that guides the wire is separated from the slit and the surrounding area is sealed, so that the tip of the wire protrudes from the wire guide and the wire is inserted into the core window. This can prevent buckling due to interference with wires wound around the wire.

In addition, when the wire passes through the core window, the wire guide is connected to the slit, so the wire enters the slit from the wire guide, reducing the diameter of the wire ring and the winding portion of the coil. Since the wire is guided in the circumferential direction of the coil, the wire can be reliably wound around the winding portion of the coil.

Therefore, the reliability and workability of winding work can be improved.

, 3', the intermediate portion IB of the wire 1 passes above the inner roller 15b from the wire guide 8 and enters the slit 10). At this time, the above 1
The wire 1 between the pair of rollers 14, 14' and the core 2.2' continues to be tensioned, and at the same time the wire 1c wound on the windings 4, 4' is tensioned.

Therefore, one end of the wire 1 is connected to the core window 3.3'.
It is possible to prevent interference with the wire IC wound around the winding parts 4, 4' when the wire is inserted into the inside. Further, the pair of rollers 12a and 12b and the pair of rollers 1
4a, 14b can be prevented from interfering with the intermediate portion IB that has entered into the slit 10 from the line guide 8.

Thereafter, as shown in Figure @8, the tip IA of the wire 1 passes through the core windows 3, 3', and the pair of rollers 13a
, 13b, the inner roller 14b retracts from the solid line position to the dashed-dotted line position as shown in FIG.
At the same time, the inner roller 15b swings from the dashed line position to the solid line position as shown in FIG. 2, and comes into contact with the outer roller 15a. Further, the movable linear guide plate 26 descends and its lower surface contacts the inner bottom surface of the opening groove 28, creating a gap approximately equal to the depth ε of the slit 10 between its upper surface and the force 11. Form.

Next, the two pairs of rollers 12a, 12b, 13m,
13b causes the tip end IA of the wire 1 to move to the wire guide 8.
When the line 1 is fed in the direction of the pair of rollers 14a and 14b, the intermediate portion IB of the line 1 behind the pair of rollers 12m and 12b is moved toward the roller 1 on the inner side of the line guide 8.
4b and enters into the slit 10.

Furthermore, the two pairs of rollers 12a, 12b, 13m,
When the tip end IA of the wire 1 is moved into the wire guide 8 and sent in the direction of the pair of rollers 14a and 14b by the rotation of the wire 13b, the intermediate portion of the wire 1 behind the pair of rollers 12a and 12b is moved. The wire ring formed by IB is the winding part 4.4'
Its diameter becomes smaller as it narrows down toward .

Thereafter, the inner roller 12b retracts from the solid line position to the position shown by the dashed-dotted line as shown in FIG. When they come into contact with each other, the tip end IA of the wire 1 is inserted between the pair of rollers 14a and 14b along the line guide 8 as shown in FIG. 4 by the rotation of the pair of rollers 13a and 13b, and At the same time, the diameter of the wire ring at the intermediate portion IB of the wire 1 is smaller, and the wire 1 is wound once around the winding portion 4.4' of the cores 2, 2', and by repeating the above-mentioned action. A predetermined number of turns can be wound, and FIG. 9 illustrates the above-mentioned effect.

As described above, the toroidal core winding device according to the present invention has
A part of the annular line guide has approximately the same shape as the line guide.
When a movable linear guide plate having a movable linear guide formed in the size of , the movable line guide is separated from the slit and surrounded by a wing, and when the upper surface of the movable line guide plate is separated from the opposing surface, the movable line guide is connected to the slit. Therefore, when the tip of the wire fed through the movable wire guide passes through the core window of the core, it can be reliably passed through the core window without interfering with the wire already wound around the winding section. , reliability and workability of winding work can be improved.

First, FIG. 10, which shows a modification of the movable linear guide plate and movable linear guide shown in FIG. 3, will be described.

In the figure, an opening groove 32 is bored between the line guide 8 and the slit 10 on the upper surface of the pace 5, and a movable line guide plate 33 is fitted into the opening groove 32 so as to be movable in the vertical direction. The upper end of a piston rod 30 of an air cylinder 29 fixed to the lower surface of the base 5 is connected to this movable linear guide plate 33.

Therefore, in this embodiment, when the movable line guide plate 33 rises due to the operation of the air cylinder 29 and its upper surface comes into contact with the lower surface of the cover 11, the line guide 8 and the slit 10
and the wire guide 8 is surrounded.

Furthermore, by operating the air cylinder 29 in the opposite direction to the above case, when the guide plate 33 is lowered and its upper surface is separated from the lower surface of the cover 11, the line guide 8 and Since the slit 10 is connected, the wire (not shown) in the wire guide 8 can enter into the slit 10.

Therefore, in this embodiment as well, the same effects as in the above-mentioned embodiments can be obtained. In addition, in the above embodiment, when the movable wire guide plate is lowered, the depth of the groove in the movable wire guide is added to the gap between the upper surface of the movable wire guide plate and the lower surface of the cover, and the thickness of the wire is Since the wire is considerably larger in comparison, when the wire enters the slit from the movable wire guide, there is a risk that the vertical position will vary and the wire will be wound so as to overlap the winding part of the core, but in this example, the groove of the wire guide Since the depth is only , it is possible to perform winding with good alignment around the winding portion of the core.

Furthermore, in the above embodiment, since the movable line guide plate moves in the vertical direction, some clearance is required between the line guide and the movable line guide. Therefore, there is a possibility that the tip of the wire may get stuck in this gap, but in this embodiment, since the wire guides are the same, the above-mentioned problem can be solved.

〔effect〕

As described above, according to the present invention, since the tip of the wire is surrounded and passed through the core window of the core, unlike the prior art, the wire protrudes into the slit adjacent to the wire guide and is wound around the winding portion of the core. Since it is possible to prevent buckling due to interference with the wire that has been attached, the reliability and workability of the winding work can be improved.
