Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a winding machine for winding a wire material for forming a coil on a multipole armature.

[0002]

2. Description of the Related Art Conventionally, a winding machine has been widely used for winding a wire rod for forming a coil around a winding core of a multipole armature. In order to improve the performance with a limited size of the armature such as a motor, the winding machine is required to have many windings in the limited winding space of the multi-pole armature. It For this purpose, so-called aligned winding is effective, in which adjacent wire rods are wound around the winding core with no gap therebetween.

For this reason, Japanese Laid-Open Patent Publication No. 8-19228 proposes a flyer type winding machine that can perform aligned winding up to the inside of the winding core. The mechanism is roughly described. As the nozzle goes through the nozzle holder toward the inner side of the winding core, the nozzle is slanted so as to approach the winding core, and the nozzle is allowed to directly penetrate deep into the winding core. Is something that can be done. Thereby, the wire rod can be accurately wound from the front end side to the inner part of the winding core.

[0004]

However, the winding machine disclosed in the above publication has the following drawbacks.
First, since the nozzle holder including the nozzle is arranged away from the center of rotation of the flyer, the flyer itself becomes large, and the main body that supports the flyer also becomes large to support the inertial force of the flyer. Further, even if the flyer is rotated at a high speed in order to increase the winding speed, the inertia is increased due to its large size, which makes it difficult.

Then, as shown in FIG. 9 (a), in order to wind more wire W, the nozzle 80 can contact the cores M adjacent to each other when it reaches the inner part of the core M. There is a nature. When the nozzle 80 comes into contact with the wire W wound around the adjacent winding cores M, the nozzle 2 and the wire W are damaged. Therefore, as shown in FIG. 9B, the tip of the nozzle 80 is made as thin as possible, but the curved surface portion 80a for preventing the strength of the nozzle 80 or the wire W from being scratched.
There is a limit to making the nozzle 80 thin in order to secure the above.

[0006] An object of the present invention is to provide a winding machine in which the entire device is miniaturized and faster and reliable winding is possible.

[0007]

In order to solve the above-mentioned problems, the first construction of the winding machine of the present invention is to wind a multi-pole armature to be wound. located apart a predetermined distance from the core, the flyer for causing winding the wire on the core by rotation of its own, mounted on the tip of the flyer, a winding machine provided with a nozzle for feeding the wire, fly

In the winding machine having such a structure, in the nozzle holder for holding the nozzle, in order to bring the nozzle close to the winding core M, the axis of the moving direction of the nozzle holder is inclined with respect to the axis of the rotary shaft of the flyer. The first guide portion that tilts and moves by being provided in the above is provided. In order to tilt the nozzle holder from the movement of the nozzle holder in the direction of the axis of rotation of the nozzle holder, the nozzle holder is placed in a plane intersecting the axis of the rotating shaft and with the axis of the rotating shaft interposed therebetween. The second guide portion is movably provided within a range extending from one side to the other side. This allows the nozzle holder to wind around the core of the multipole armature without moving away from the axis of the flyer's axis of rotation. That is, the flyer itself can be downsized, and the main body that supports the flyer itself can also be downsized. Since the flyer itself is downsized, its inertial force is reduced, so that the rotational speed of the flyer can be increased. This makes it possible to reduce the manufacturing time for each multipole armature.

In the winding machine having such a structure, the nozzle has its tip cut so that it does not come into contact with the adjacent wound core. As a result, the nozzle can be moved to the inner part of the winding core to be wound without contacting the adjacent wound winding core. That is, it is possible to perform the aligned winding up to the inner part of the winding core and increase the number of windings.

FIG. 2 is a plan view of the drive portion of the main body 6. The flyer rotation motor 5 is attached to the main body 6, and from the pulley 23 attached to its output shaft 5a (see FIG. 1),
Through the timing belt 24, the spindle shaft 21 (see FIG.
The pulley 25 attached to (see) is rotated. Since two flyers 3 are provided in parallel in this embodiment,
The flyer rotation motor 5 rotates two spindle shafts 21 (see FIG. 1), but the spindle shaft 21 may be one or plural. As shown in FIGS. 1 and 3, a slide member moving motor 26 is provided to move the slide shaft 19 in the axial direction of the spindle shaft 21. The slide member moving motor 26 is attached to the moving member 27. The motor 26 for moving the slide member is the coupling 2
It is provided so as to rotate the ball screw shaft 29 through 8. The ball screw shaft 29 converts a rotational movement into a linear movement by a ball screw 30 attached to the main body 6. As shown in FIG. 1, the slide shaft 19 rotates with the rotation of the spindle shaft 21, but the moving member 27 does not rotate. Therefore, the bearing 3 for allowing the rotation to escape.
1 is provided.

Further, as shown in FIG. 3, a guide shaft 32 for guiding the movement of the moving member 27 is attached to the moving member 27. A stopper 33 is provided on the guide shaft 32 to limit the amount of movement of the guide shaft 32, and the stopper 33 contacts the slide bearing 34 fixed to the main body 6 so that the slide shaft 19 ( (See Figure 1)
Is the direction approaching the multi-pole armature C (see Fig. 1) (forward direction)
The amount of movement to is limited. Further, a fixing plate 35 is fixed to the side of the guide shaft 32 opposite to the side on which the moving member 27 is attached, and the stopper bolt 3 is attached to an arbitrary position of the fixing plate 35.
6 is arranged. The slide shaft 19 (see FIG. 1) attached to the moving member 27 is in contact with the main body 6 by the stopper bolt 36 so that the amount of movement in the direction away from the multipole armature C (see FIG. 1) (retraction direction) is limited. To be done. The positions of the stopper 33 and the stopper bolt 36 can be arbitrarily changed. Further, the main body 6 is provided with a displacement sensor 37, which measures the amount of movement of the moving member 27 and controls the position by a control device (not shown).

Returning to FIG. 1, the slide member moving motor 2
6 is a ball screw shaft 29 through a coupling 28
When is rotated, since the ball screw 30 is immovably fixed to the main body 6, the slide member moving motor 26 relatively moves. At the same time, the moving member 27 to which the slide member moving motor 26 is attached also moves in the direction parallel to the axial direction of the spindle shaft 21. This allows
The slide shaft 19 is rotatably attached to the moving member 27, so that the slide shaft 19 can move in parallel in the axial direction of the spindle shaft 21. Further, the guide shaft 32 (see FIG. 3) for guiding the movement of the slide member moving motor 26 is also
Spindle shaft 2 inside slide bearing 34 (see FIG. 3)
1. Move in a direction parallel to the axis direction of 1.

4 and 5 are a front view and a plan view of the vicinity of the flyer 3. A linear rail 38, which is the first guide portion 15, is attached to the tip of the flyer 3 with screws or the like. The nozzle 2 is coupled to the nozzle holder 14 and the nozzle holder 14
Via the linear guide 39 attached to himself,
It is movably arranged in the direction of a linear rail 38 arranged on an inclined trajectory approaching the winding core M. Further, the nozzle holder 14 has a linear rail 40 which is the second guide portion 16.
However, the flyer 3 is attached with screws or the like at right angles to the rotating axis direction of the flyer 3. The linear guide 41 corresponding to the linear rail 40 is attached to the slide member 70 on the slide plate 18 side. The linear guide 41 does not move the slide plate 18 in the direction perpendicular to the axis of rotation of the flyer 3,
It is possible to guide the nozzle holder 14 in the moving direction of the linear guide 41.

Further, since the wire W has a structure which is passed through the inside of the slide shaft 19 and is paid out, a guide portion 42 is provided at the tip of the slide shaft 19 in order to smooth the payout of the wire W. Then, the slide shaft 19 rotates together with the spindle shaft 21 and the flyer fixture 20,
In addition, key grooves 19a are provided at a plurality of positions for moving forward and backward. In addition, slide keys 43 that engage with the key grooves 19a are provided at a plurality of locations on the flyer fixture 20.

FIG. 6 is a diagram showing a winding process of the winding machine 100 of the present invention. When the slide shaft 19 is moved forward by the slide member moving motor 26 (see FIG. 3), the slide plate holding member 17 attached to the slide shaft 19 moves the slide plate 18 forward. At the same time, the linear guide 41 attached to the slide plate 18 presses the linear rail 40 in the forward direction. However, since the linear guide 41 cannot move in the forward direction, the nozzle holder 14 to which the linear rail 40 is attached is arranged so that the linear guide 39 fixed to itself is different from the axial direction of the spindle shaft 21. It moves on the linear rail 38 and brings the nozzle 2 close to the winding core M. That is, the linear guide 41 and the linear rail 40 that are the second guide portions 16 are in a direction perpendicular to the forward movement direction in order to move the slide plate 18 forward from the forward movement so that the nozzle holder 14 is inclined to move toward the winding core M. Since it is movably installed in the nozzle holder 14 without bending the slide plate 18,
Allows tilt movement of.

When the nozzle 2 reaches the inside of the winding core M, the flyer 3 rotates and the wire W fed from the nozzle 2 is wound around the winding core M. In accordance with the end of the winding core M on the first round, the nozzle 2 is retracted by the thickness of the wire W.

FIG. 7 is a diagram showing a winding process following FIG. During the winding of the first layer, the slide shaft 19 retracts according to the winding position. At the same time, the slide plate 18 also moves backward. At this time, the linear guide 41 attached to the slide plate 18 presses the linear rail 40 in the backward direction.
However, since the linear guide 41 cannot move in the backward direction, the nozzle holder 14 to which the linear rail 40 is attached is arranged so that the linear guide 39 fixed to itself is different from the axial direction of the spindle shaft 21. It moves on the linear rail 38. As a result, the nozzle holder 14 tilts on the linear rail 38 and separates the nozzle 2 from the winding core M.

When the nozzle 2 is located at the center of the winding section of the winding core M, the centers of the linear guides 39 and 41 are located at the center positions of the linear rails 38 and 40 and on the axis of the spindle shaft 21. To be done. That is, the nozzle holder 1
In the winding section 4, the linear rail 40 attached to the nozzle holder 14 is attached to the linear guide 41 attached to the slide plate 18, and the nozzle holder 1
The linear guide 39 attached to the No. 4 moves with respect to the linear rail 38 attached to the flyer 3 by an equal distance from the axis of the spindle shaft 21.
From the above, even if the nozzle holder 14 is moved by the slide plate 18, the spindle shaft 21 is moved within the winding section.
The amount of movement from the axis of
The change in the inertial force of the flyer 3 due to the movement of 4 is minimized.

FIG. 8 is a diagram showing a winding process following FIG. As the slide shaft 19 moves forward and backward, the nozzle 2 moves toward and away from the winding core section, and the wire W is wound around the winding core M. When the winding of all the winding cores M is completed, the slide shaft 19 retracts, and the slide plate 18 also retracts. This separates the nozzle holder 14 and the nozzle 2 from the multipole armature C via the linear guides 39 and 41 and the linear rails 38 and 40. Then, the tilt movement of the nozzle 2 and the rotation of the flyer 3 are stopped at a position away from the multi-pole armature C. After the wire W is locked by the elastic member 11 (see FIG. 1) attached to the indexing rotary shaft 7, the cutter 12
(See FIG. 1).

Next, the nozzle 50 of the present invention will be described. FIG. 10 is a sectional view of the nozzle 50. Nozzle 50
As shown in FIG. 10 (a), the tip end of the wire is cut so that it does not come into contact with the wire W wound around the adjacent winding cores M, which is not the winding core M side to be wound. . That is, as shown in FIG. 10B, at the tip of the nozzle 50, the winding core M side to be wound is left as the semicircular cylindrical portion 50b, and the adjacent winding core M side is removed. As a result, the nozzle 50 can be inserted deep into the winding core M. Further, at the tip of the nozzle 50,
The curved surface portion 50a is provided so that the wire W is not scratched, which is called a pinhole.

FIG. 11 is a diagram showing the locus of movement of the nozzle 50 with respect to the winding core M during winding. When winding the nozzle 50 while rotating around the outer periphery of the winding core M during winding, the surface of the curved surface portion 50a of the nozzle 50 facing the axis of the spindle shaft 21 (see FIG. 1) of the nozzle 50, that is, Only the semicircular cylindrical portion 50b of the nozzle 50 comes into contact with the wire W. As a result, the nozzle 50 can cut a portion where the wire W does not come into contact with the nozzle 50, and can be moved further into the core M during winding.

Further, as shown in FIG. 12, as the shape of the tip of the nozzle 50, the following examples can be given. As shown in FIGS. 12 (a) and 12 (b), even if the cutting is performed at an angle β which is an angle larger than the inclination angle α of the nozzle centering on a point 50c closest to the axis side of the spindle shaft 21 of the nozzle, It will be possible to enter the core C deep.

The embodiment of the present invention has been described above.
