Next, the operation of the winding machine of the embodiment will be described.

When the lead 11 is driven to rotate by rotating the motor 11, the ball nut 2 engaged with the lead 10 is rotated.
2 and the tubular member 19 connected thereto is advanced, and as shown in FIGS. 1 and 3, the holding portion 6 is inserted into the shaft support portion 1 a of the armature core 1 transported by the transport mechanism 5. Become. Shortly before the insertion state, the cylinder device 24 is driven to move the center shaft 20 backward, whereby the cylindrical member 29 and the cylindrical member 31 are retracted relatively to the chuck body 28, Tapered surface 31b of tubular member 31
Then, the engagement with the tapered surface 28b of the chuck body 28 is released, the chuck portion 28a opens, and the shaft support portion 1a of the armature core 1 is inserted therein. And the cylinder device 2
4 is driven to advance the central shaft 20, the cylindrical member 31
Is advanced by the coil spring 24 and the chuck portion 28
The shaft support 1a of the armature core 1 is sandwiched between the armature core 31a and 31a. At this time, the commutator 1c of the armature core 1 is covered by the tubular member 32 (see FIG. 16).

Next, the motor 11 is rotated in the reverse direction to retract the tubular member 19. As a result, the armature core 1 held by the holding portion 6 is transported rearward, and is in the state shown in FIG. Then, the cylinder 63 is driven to advance the center shaft 52, and the armature core 1 is held between the pair of formers 2 provided at the tip of the center shaft 52.

Next, the tip of the winding M is gripped by the wire chucks 59 and 61 (see FIG. 6). The motor 48 is driven to rotate the tubular member 46 half a turn. Here, since the tubular member 51 is spline-coupled to the tubular member 46, the tubular member 51 rotates, the flyer 3 also rotates, and the winding supplied from the winding supply passage 51a is connected to the armature. It is arranged so as to cross the end of the iron core 1. After this, the tongue retainer 64
To move the winding M to the commutator 1c of the armature core 1.
(See FIG. 7).

Next, by continuously rotating the motor 48,
By rotating the flyer 3 continuously, the winding supplied from the flyer 3 is wound around the groove 1e around the armature core 1 (see FIG. 8). At the time of this winding, the flyer 3 is attached to the cylindrical member 51 so as to be evenly wound in the groove 1e.
Are appropriately moved in the axial direction. That is, by rotating the motor 44, the lead 42
Is rotated, and the ball nut 53 meshed with the
Is moved along the lead 42, whereby the cylindrical member 51 is moved in the axial direction to move the flyer 3.

As described above, one groove 1e of the armature core 1 is formed.
When the winding M is wound around the commutator 1 of the armature core 1
The operation | work which winds the winding M around the tongue 1d formed in c is performed.

That is, as shown in FIG. 15, the tubular member 32 covering the commutator 1c is driven backward to
The tongue 1d is exposed. 10 and FIG.
As shown in (a), the flyer 3 is rotated by rotating the motor 48 so that the winding M passes over the tongue 1d. Next, the tongue holder 64 is moved in the radial direction of the commutator 1c, and the winding M is pressed against the tongue 1d.

Next, the motor 48 is rotated in the reverse direction to rotate the flyer 3, and the winding M is hooked on the tongue 1d (FIG. 1).
1, FIG. 14 (b) and FIG. 12). At this time, the position of the flyer 3 is adjusted by rotating the motor 44 so that the winding M is wound around the tongue 1d smoothly. Further, the motor 48 is rotated in the reverse direction to rotate the flyer 3 in the reverse direction, and the winding M is wound around the tongue 1d (see FIGS. 13 and 14C).

Next, the tubular member 32 is advanced to drop the winding M between the tongue 1d and the commutator 1c. Thereby, the winding M is completely locked by the tongue 1d.

Next, the cylinder 63 is driven to drive the center shaft 54.
Is retracted. And
The motor 17 of the index mechanism 4 is rotated to rotate the cylindrical member 15. Here, since the tubular member 19 having the armature core 1 sandwiched by the holding portion 6 at the distal end is spline-connected to the tubular member 15, the tubular member 19 rotates together with the tubular member 15, and the armature is rotated. The iron core 1 is rotated about an axis. Then, when the groove 1e of the armature core 1 rotates by one step, the rotation of the motor 17 is stopped.

Thereafter, the cylinder 63 is driven to move the former 2 forward, the armature core 1 is sandwiched between the formers 2, and the winding M is wound in the same procedure as described above.

When a predetermined number of turns of the winding M are wound in all the grooves 1e, the rotation of the motor 48 is stopped, and then the wire chucks 59 and 61 are moved outward to apply tension to the winding M. And the winding M is cut at the tongue 1d (see FIG. 9).

Thereafter, similarly to the above, the cylindrical member 19 is advanced toward the transport mechanism 5 by rotating and driving the motor 11, and the armature core 1 on which the winding M has been wound is transferred to the transport mechanism 5. Delivery, and then receive the armature core 1 on which the winding M is to be wound. Then, the tubular member 19 is retracted by reversing the motor 11, and the armature core 1 is positioned between the formers 2. Thereafter, an operation of winding the winding M is performed in the same procedure as described above.

As described above, the index mechanism 4 of the winding machine is used.
Can be moved toward the transport mechanism 5, there is no need to provide a delivery mechanism in addition to the winding machine, and the manufacturing cost of the apparatus increases, and the transport mechanism 5 and the winding machine are connected to each other. The present invention can also be applied to a case where they are arranged close to each other.

[0027]

As described above, according to the winding machine of the present invention, the armature core, which is sequentially conveyed by the conveying mechanism and has a plurality of grooves formed in the circumferential direction, is clamped by the index mechanism. In a winding machine for sequentially winding windings fed from a flyer around each axis while rotating intermittently around an axis, the index mechanism is configured to advance / retreat with respect to an armature core on a transfer mechanism,
Holds the armature core when the index mechanism moves forward / backward
Since the transfer of the armature core to and from the transfer mechanism is performed by performing the above operation, that is, since the index mechanism also has a function of transferring the armature core to and from the transfer mechanism, the transfer mechanism of the armature core as in the related art is used. There is no need to provide it separately,
Therefore, while suppressing the manufacturing cost of the device related to the winding,
The armature core can be reliably transferred to and from the transport mechanism, and the transport mechanism can be arranged close to the winding machine.
