Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an aligned winding device for manufacturing a winding coil by winding a plurality of wires adjacently around a winding frame with a good space factor.

[Background technology and its problems]

A wire-wound coil (hereinafter referred to as a double coil) in which two wires are arranged adjacent to each other alternately (hereinafter referred to as a double coil) has the following advantages: Yes, and the battery life will be relatively long.

(2) Since the coil is double, control within the driver is possible.

(3) By connecting the coils in series or in parallel, it can be used for both headphone and microphone.

It has the following features.

In order to take advantage of the above-mentioned features, it is necessary to wind the double coil in an aligned manner. Conventionally, the aligned winding of the double coil has been carried out by the method shown in FIGS. 1 and 2.

Figures 1a and b show each coil layer alternately with wire A,
In this method, the wires A and B forming each coil layer are made to cross each other on the coil at the end of the winding, and are routed to the winding start position.

In this method, the wires A and B are crossed, which increases man-hours and costs, and the space factor decreases due to the crossed portion. Furthermore, when adhering and fixing the wires A and B to each other, there are problems such as the wires A and B crossing each other.

Figures 2a and 2b show a method in which two wires A and B are started winding adjacent to each other and returned to the winding starting position in the second layer.

In this method, wires A and B start from m turns (m
+1) Two wires A and B when transitioning to a turn
Because of the deviation in the direction of the winding axis, wires A and B
The contact pressure between the wires increases, and the adjacent wires A,
It becomes easier to climb onto B. In addition, when one coil layer is formed with wires A and B, and wires A and B normally ride on the coil layer at the traverse turning point where wires A and B are folded back to form the next coil layer, as shown in Figure 2. The windings are aligned as in Figure 2b, depending on the state of wires A and B.
If the windings run over each other, the aligned windings will collapse and become irregularly wound, resulting in problems such as a decrease in the yield of the aligned windings.

[Purpose of the invention]

This invention was made in view of the above points, and it is possible to manufacture double coils with high space factor and yield.
The present invention provides an aligned winding device that can be manufactured at low cost.

[Summary of the invention]

In order to achieve the above object, the present invention arranges the first and second wires at a predetermined interval in the direction of the winding axis of the winding frame without misalignment in the direction of the winding axis,
A wire locking means for locking the winding frame and the first and second wires is rotated by a rotating mechanism around the winding frame, and after the first wire is wound around the winding shaft for a predetermined length, the second wire is wound around the winding frame. Since the double coil is guided by the first wire and wound around the winding shaft, the space factor of the double coil can be increased, stable winding can be achieved, and the device can be of a simple configuration.

〔Example〕

The aligned winding device of the present invention will be briefly explained with reference to the principle diagram in FIG. 3 and the explanatory diagrams in FIGS. 4 and 5.

As shown in FIG. 3, first and second wires (hereinafter simply referred to as wires) 28 and 29 are arranged at a distance H on a plane perpendicular to the winding shaft 6. It is guided by second wire guides (hereinafter simply referred to as wire guides) 26 and 27, and both wire guides 26 and 27 are configured to reciprocate at a predetermined speed along the width direction of the winding shaft 6. .

The starting ends of the wires 28 and 29 are held by a clamp mechanism 12, which will be described later, before starting winding, and the guide rotor 9 provided with the clamp mechanism 12 and the winding shaft 6 are configured to rotate clockwise in synchronization. There is.

At the initial stage of winding, the clamp mechanism 12 is in the position shown in FIG.
Holds 29. When the guide rotor 9 rotates a certain angle clockwise and the clamp mechanism 12 comes to the position, the wire 28 first contacts the winding shaft 6 at a point P as shown by the dotted line. At this time, the wire 29 is still attached to the winding shaft 6.
Do not come into contact with

Then, when the clamp mechanism 12 further rotates and comes to the position, the wire 29 also comes into contact with the winding shaft 6 at a point Q as shown by a chain line. At this time, wire 28
has already been wound around the winding shaft 6 by a distance PQ. Thereafter, as the winding shaft 6 and the clamp mechanism 12 rotate, the wires 28 and 29 are attached to the winding shaft 6.
It will be wrapped around the wire guide 2.
Wires 28, 29 drawn out from 6, 27
The winding position is always a point P, which is separated by a certain angle.
Q, and it gets caught up with a difference of distance PQ. Therefore, the wire 29 wound later is guided by the wire 28 and wound while following its outward path, so that it can be wound in an aligned manner as shown in FIGS. 4a and 4b.

Note that, as described below, this method also has some problems at the initial stage of winding. That is, if the wire guides 26 and 27 are arranged on a plane perpendicular to the winding axis direction, the wire 29 that is later wound up when the clamp mechanism 12 rotates from the position shown in FIG. There may be cases where it overlaps the wire 28.

At this time, if the wires 28 and 29 are positioned as shown in FIG. As a result,
After the wire 28 is pushed out to the right, the fifth
The winding will be as shown in Figure b. In this case, wire 2
At the beginning of winding 8 and 29, the windings are not aligned and the yield of double coils is less than 60%.

Therefore, in the second embodiment of the present invention, a wire locking means is further provided to cause the winding to become aligned when winding the wire around the winding shaft 6.

The aligned winding device provided with this wire locking means will be explained with reference to the principle diagram in FIG. 6 and the sectional view of the clamp mechanism in FIG. 7.

First, as shown in FIG. 6, the clamp mechanism 12 attached to the side surface (back surface) of the guide rotor 9
The configuration and operation of A will be explained with reference to FIG.

FIGS. 7a and 7b are cross-sectional views of the clamp mechanism attached to the guide rotor 9. In these figures, the cam follower 13 is moved by a cam (not shown).
When pushed downward on the paper, the spring constants of the compression springs 19 and 20 are set such that compression spring 19 < compression spring 20, so the guide pin that is integrally supported with the cutter shaft 14 and the connecting rod 16 1
5 and the sleeve 18 protrude from the surface of the guide rotor 9 as shown in FIG. 7b. When the pressure of the cam is released, the cutter shaft 14, guide pin 15 and sleeve 18 return to their original state as shown in FIG.
Return to state.

Therefore, if the wires 28 and 29 are hooked to the tip of the cutter shaft 14 in the state shown in FIG.
7 and the cutter shaft 14, the wires 28, 2
Cut off the extra length of 9 and cut off the cutter shaft 14.
The tips of the wires 28 and 29 are held between the tips of the wires 28 and the sleeve 18. Further, the guide pin 15 holds only the wire 28 between its tip and the guide rotor 9, as shown in FIG. In this way, the clamp mechanism 12A cuts the wires 28 and 29, and only the wire 28 is attached to the guide rotor 9 by the pin 15.
It will be held on the side.

Next, the winding operation will be briefly explained with reference to FIG.

When the clamp mechanism 12A provided on the guide rotor 9 is in the position shown in FIG. 6, the clamp mechanism 12A becomes the state shown in FIG. Wrap it around the tip of the cutter shaft of the mechanism 12A.

Then, while the clamp mechanism 12A is in the position, the pressure of the cam is released as described above, and the clamp mechanism 12A returns to the state shown in FIG. 7a. At this time, the cutter shaft 14 cuts off the extra lengths of the ends of the wires 28 and 29 and holds them. And wire 2
8 is held at the tip of the guide pin 15 in a stretched state.

While the clamp mechanism 12A rotates to the position, the wire 29 passes over the guide pin 15 and intersects with the wire 28 on the opposite side of the guide rotor 9 (on the near side in the drawing). Then, when the clamp mechanism 12A comes to the position, the wire 28 comes into contact with the winding shaft 6 first at the point P. Furthermore, when the clamp mechanism 12A rotates to the position, the wire 2
9 touches the winding shaft 6 at a point Q. At this time, wire 29
Since the wires are guided to the winding shaft 6 in a state where they intersect with the wire 28 and come into contact with it, the wires do not ride on the wire 28 and form aligned windings as shown in FIGS. 4a and 4b. Thereafter, the wires 28 and 29 are always wound with a difference of the distance PQ.

Therefore, according to this second embodiment, the winding condition as shown in FIG. 5 described above, which occurs at the beginning of winding, can also be avoided.

In Fig. 8 a, b, and c, the wire 29 is connected to the guide pin 1.
5 is a diagram showing another shape of the tip portion of the guide pin 15 that allows the guide pin 15 to easily pass over the guide pin 15. FIG.

FIG. 9 is a front view of an aligned winding device to which the present invention is applied, and FIG. 10 is a side view of the lower half of the guide rotor shown in FIG. 9 in a vertical section.

In these figures, 1 is a motor, 2 is a spindle shaft connected to the shaft of the motor 1, 3 is a compression spring loaded between the spindle shaft 2 and the sleeve 4, and 5 is attached to the tip of the spindle shaft 2. The winding frame is composed of a winding shaft 6 fixed to a spindle shaft 2, a side plate 7 fixed to a sleeve 4, and a side plate 8 that can be freely engaged with and detached from the winding shaft 6 using a ball plunger or the like.

A guide rotor 9 is fixed to the spindle shaft 2, and a slide pin 10 passes through the guide rotor 9, and is urged by a compression spring 11 so as to come into contact with the side plate 7. 12A and 12B are the clamp mechanisms explained in FIG.
1 is moved left and right in Figure 10. Reference numeral 24 denotes a lever that presses the slide pin 10, and by pushing the slide pin 10 with the operation of the jig cylinder 25, the side plate 7 is moved left and right in FIG. 2
6 and 27 are wire guides for the wires 28 and 29.

Note that two clamp mechanisms 12A and 12B were arranged with a phase difference of 180 degrees in order to continuously manufacture double coils.

Next, manufacturing of the double coil will be explained.

First, the jig cylinder 23 is operated to move the cam 21 forward, and the motor 1 is started to move the jig cylinder 23 forward.
As explained in the figure, the clamp mechanism 12A holds the wires 28 and 29 and starts winding them around the winding shaft 6, and the jig cylinder 23 is returned to its original position, and the cam 21
to retreat. Then, during the final winding of the wires 28 and 29 around the winding shaft 6, the jig cylinder 23 operates again to advance the cam 21, and this time the clamp mechanism 12B is activated as shown in FIGS. 6 and 7. 29 (Fig. 7a), and clamp mechanism 1
2A is the wire 28, 29 by the pressure of the cam 21.
It stops in the state where it is released (Fig. 7b). In this state, remove the side plate 8 from the winding shaft 6 and press the jig cylinder 25.
When the lever 24 is activated, the slide pin 10
is pushed in the direction of the side plate 7, so the formed double coil comes off from the winding shaft 6. When the jig cylinder 25 returns to its original position, the biasing force of the compression spring 3 causes the side plate 7 and slide pin 10 to return to their original positions.

At the same time, the jig cylinder 23 also returns to its original position, so that the clamp mechanism 12A is released from the pressure of the cam 21 and enters the state shown in FIG. 7a.

After that, the side plate 8 is locked to the winding shaft 6, and the motor 1 is
When activated, a double coil is formed as described above.

As described above, the wires 28 and 29 are arranged without positional deviation in the direction of the winding axis, and the clamp mechanisms 12A and 12B are
With the configuration in which the cutter shaft 14 and the guide pin 15 are provided at a predetermined interval, it is possible to manufacture the double coil, which is the intended purpose, with good space factor, good yield, and low cost. In addition, the aligned winding device can be simply configured by adding a clamp mechanism 12 (A, B) to the conventional device.
