[0016]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 1, on a winding machine main body 2 of a multiple winding machine 1, a plurality of winding devices 4 for feeding out a wire 3 for winding are arranged at predetermined intervals. ing. Further, as a holding means for holding the armature 10 which is a winding frame around which the wire 3 fed from the winding device 4 is wound and disposing it at a predetermined winding position or a standby position, a plurality of indexes 20 are provided. It is provided so as to face each winding device.

As shown in FIG. 2, the armature 10 includes an armature body 13 including a plurality of cores 11 and slots 12 formed between the cores 11, and an armature 13 extending vertically from the armature body 13, and (Commutator) 15. From the base end side of the commutator 15, a tongue 15a extends in the direction of each core 11, and the wire 3 is tied thereto.

Each of the winding devices 4 has a rotatable spindle 5, and each of these spindles 5 has
A flyer 6 is arranged at a predetermined distance from the center axis of the rotation. The wire 3 is fed out through the nozzle 7 attached to the flyer 6 to the armature 10 held by the index 20 facing the winding device 4.

In order to guide the wire 3 fed from the nozzle 7 to the slot 12 of the armature 10 where the wire 3 is to be wound, a center former 30 is supported in front of the spindle 5 as guide means for the wire 3. You.

As shown in FIG. 3, the center former 30 is rotatably supported by the spindle 5 via a support shaft 31, and extends toward the armature 10 by expansion and contraction of the support shaft 31, Center Former 3
The tip of one of the cores 11 of the armature 10 is fitted into the grip 32 at the center of the tip of the arm 10, and the wire 3 is guided to the slot 12 of the amateur 10 while guiding the wire 3 from the grip 32 at an inclined portion 33 forming a gentle slope. When each spindle 5 rotates in this state, the wire 3 slides on the inclined portion 33 of the center former 30 and the amateur 10
Is wound around the core 11.

In this case, the center former 30 fitted to the amateur 10 at the grip portion 32 is
, The non-rotation with respect to the amateur 10 is maintained. Therefore, the center former body 3
4, a weight portion 35 is fixed at a position (below) deviated from the center, and the center former 30 has a center of gravity below the center axis of the spindle 5 as a whole to maintain balance. ing.

Further, when the index shaft 20 rotates as described later, the center shaft 30 contracts the support shaft 31 into the spindle 5 so as not to interfere with the rotation.
From the gripping position where it is fitted to the core 11 to the retracted position on the spindle 5 side.

In this case, a fitting recess 36 is formed on the surface of the center former 30 facing the spindle 5 at the rear of the center former 30 so that the center former 30 which has not been fitted with the amateur 10 becomes unstable. In the figure, the fitting recess 36 is shown in a partially cutaway cross section of the center former 30). When the center former 30 retreats toward the spindle 5, the fitting recess 36 corresponds to the fitting recess 36. The fitting protrusion 37 fixed at the position is fitted.

The winding device 4 can be moved in a three-dimensional direction by a three-dimensional moving mechanism (not shown). The winding operation of the armature 10 on the slot 12 and the winding of the wire 3 on the tongue 15a are performed. It is also possible to perform entanglement work.

On the other hand, the plurality of indexes 20 are shown in FIG.
As shown in FIG. 4, at both ends 21 and 22, an insertion hole 23 into which the vertical shaft 14 of the armature 10 is inserted is shown (only the winding-position-side end 21 is shown in the figure). At 23, amateur 10 has index 20
At both end portions 21 and 22.

The index 20 holding the armature 10 at both ends 21 and 22 is attached to the armature 10 on the end 21 side.
Is disposed at a winding position facing the winding device 4, and the end 2
The armature 10 on the second side is arranged at a standby position which is 180 degrees inverted from the winding position. However, since the index 20 is rotatable about the rotation shaft 40, after this rotation, the rotation is reversed. , Amateur 1 on the end 22 side
0 is located at the winding position, and the armature 10 on the end 21 side is located at the standby position.

In this case, the armature 10 on the winding position side is wound by the winding device 4 while the armature 10 with respect to the index 20 is wound on the standby position side.
The armature 10 on the standby position side waits in the standby position until the winding of the armature 10 on the winding position side ends, and after the winding of the armature 10 on the winding position side ends, the index As the 20 rotates, it moves to the winding position side to form a winding.

Each index 20 is covered from above by an index cover 24 during winding. When each index 20 is rotated, the index cover 24 is driven by the actuator 25 to move upward so as not to interfere with the rotation of the index 20.

The rotating mechanism of the index 20 is as follows. That is, as shown in FIG. 5, the vertically arranged rotating shaft 40 is fixed below the index 20, and is rotatably supported by the winding machine main body 2 via a bearing. Further, a pinion 41 is fixedly provided coaxially with the rotating shaft 40 at a lower end portion of each rotating shaft 40, and a rack 42 is erected in the winding machine main body 2 in a horizontal direction so as to mesh with these pinions 41. You.

In order to drive the rack 42, the winding machine main body 3 is provided with an actuator 43.
Can move along the erected straight line.
When each pinion 41 rotates according to the movement of the rack 42, this rotation is transmitted to each index 20 via the rotation shaft 40, and each index 20 rotates synchronously from the winding position to the standby position. Has become.

When the rotation position of the index 20 is determined by the rack 42 and the pinion 41 as described above, the position of each index 20 is adjusted so that each armature 10 is correctly adjusted by the play of the rack 42 and the pinion 41. It may deviate from the correct direction for turning to the winding position.

For this reason, in the present invention, as shown in FIG. 6, regulating plates 27 for sandwiching both side portions 26 of each index 20 at predetermined positions are fixed to both sides of the concave portion 60 of the index cover 24, and The rotation position of the index 20 is regulated by being held by the regulating plate 27 so that each index 20 is fixed at an accurate rotation position.

Since the regulating plate 27 is fixed to the index cover 24 in this manner, the index cover 24
When the index 20 rotates, the index 20 moves upward, is retracted so as not to hit each of the rotating indexes 20, and each of the indexes 20 having completed the rotating operation is moved from above to the index cover 2.
4, the side surfaces 2
6 can be fixed to maintain the correct orientation.

Further, in the present invention, as a holding means for holding the position of the armature 10 at the winding position, the armature holding cylinder 16 is fixed above the concave portion 60 of the index cover 24. And index cover 2
When the arm 4 is lowered so as to cover the index 20, the arm cylinder 16 is located at a position where the tip thereof contacts the arm 10 from above, and the vertical shaft 14 of the arm 10 is accommodated in the hollow portion of the arm 16. Then, the armature 10 is pressed down from above to maintain the position of the armature 10.

The armature holding cylinder 16 also moves up and down together with the index cover 24 in the same manner as the regulating plate 27. Therefore, when the index 20 rotates, it moves upward together with the index cover 24 to move the index 20 and the armature held by the same. 10 so that it does not interfere with the rotation operation.
When the index cover 24 is lowered after the rotation operation of the armature 0 is completed, the armature holding cylinder 16 is again moved to the armature 1 position.
The armature 10 descends to a position where it touches 0, and is fixed so that the amateur 10 does not move. The hollow portion of the amateur holding cylinder 16 has a sufficient size so as not to interfere with the commutator (commutator) 15 of the amateur 10.

As shown in FIG. 4, each index 20 is provided with a wedge member 28 having a wedge-shaped portion at the tip in order to prevent the rotation of the armature 10, and the wedge member 28 is provided with a spring. The armature 10 is urged to extend from the index device 15 and fit into the slot 12, thereby holding the armature 10 at a predetermined rotational position. The expansion and contraction of the wedge member 28 is performed synchronously with respect to all the indexes 20 by driving the connecting member 70 extending upward from the wedge member 28 by the actuator 71 (see FIG. 1). I have.

An indexing device 45 is provided on the winding machine main body 3 so as to be able to move up and down so as to be located below the slot 12 of the armature 10 at the winding position. The indexing device 45 is rotatable about a central axis, and a fitting portion 46 is fixedly provided at a predetermined distance from the central axis. Thus, when indexing the slot 12 to be wound into a predetermined position, the wedge member 2
8 and the slot 12 of the amateur 10, which has been released from being fixed by the amateur holding cylinder 16, is fitted into the slot 4 from below.
When the indexing mechanism 45 is rotated by fitting the armature 6, the armature 10 is rotated at a predetermined rotation angle (for example, for one slot).
And can be rotated.

Further, the winding machine main body 3 is provided with a clamping device 50 movable with respect to each index 20 for each winding device 4 and each index 20, and is fed out from the nozzle 7 of the winding device 4. After being clamped by the clamp device 50, the wire 3 is guided to the amateur 10 side.

As shown in FIG. 4, the clamp device 50 includes a fixed upper clamp plate 51 and a vertically movable lower clamp plate 52 for clamping the wire 3 therebetween. Further, a slide plate 53 having an inclined surface formed on an end surface is fixed to the side of the lower clamp plate 52, and when the unnecessary wire 3 clamped by the clamp device 50 is discarded, the lower clamp plate 52 is disposed. Is lowered, and the wire rod that has lost support from the lower clamp plate 42 slides down along the inclined surface of the slide plate 53.

Next, the operation will be described.

In order to perform winding by the multiple winding machine 1, first, a plurality of armatures 10 to be wound are inserted into the insertion holes 23 of the end 21 of the index 20 on the standby position side, and the index After raising the cover 24, the rack 42 is moved on a straight line to
Is inverted.

Thus, each index 20 arranges a plurality of amateurs 10 to be wound on the winding position side.
By lowering the index cover 24 in this state, the regulating plate 27 fixed to the index cover 24 sandwiches both side portions 26 of each index 20 and fixes each index 20 to a predetermined position accurately. I do.

Each of the amateurs 10 also has an amateur holding cylinder 16 fixed to the index cover 24.
And the wedge member 41 extending from the index 20 is fitted into the slot 12,
Its position is fixed.

Next, the winding device 4 is driven by a three-dimensional moving mechanism, and turns around the tongue 15a of the commutator 15 of the armature 10 so that the wire 3 fed from the winding device 4 is tangled. 15a.
In this case, the wire 3 is clamped by the clamp device 50 on the extended end side, so that the wire 3 at the portion between the clamp device 50 and the nozzle 7 is entangled with the tongue 15a. Become.

When the tangling to the tongue 15a is completed, the clamp device 50 is moved, and the wire 3 is cut between the clamp device 50 and the tongue 15a. At this time, unnecessary wires 3 remaining on the clamp device 50 side slide down the slope of the end surface of the slide plate 53 by lowering the lower clamp plate 52, and are disposed below the clamp device 50 (not shown). Discarded in a waste box.

Subsequently, the winding device 4 is advanced and the nozzle 7
Is moved to a predetermined position close to the slot 12 of the amateur 10, and then the spindle 5 is rotated to remove the wire 3 guided by the center former 30 to the amateur 10.
Is wound around the slot 12. At this time, the winding is performed while the winding device 4 is moved so as to cross the armature 10, so that the slots 12 are wound in an aligned state, and the space factor can be improved.

When the winding to the slot 12 is completed, the wire 3 is entangled with the tongue 15a of the amateur 10, and
Subsequently, in order to perform winding on the next slot 12, the wedge member 28 is temporarily retracted, and the index cover 2 is moved.
4 is lifted to release the fixing by the amateur holding cylinder 16. And in the slot 12 of the amateur 10,
The slot 12 to be wound next is arranged at a predetermined position by fitting the fitting portion 46 of the indexing device 45 from below and rotating the indexing device 45 by one slot of the armature 10. Thereafter, a new winding to the slot 12 is performed in the same procedure as described above.

By repeating the above procedure by the number of slots 12 of the amateur 10, the winding work on the amateur 10 in the first round is completed. After the winding operation, the wire 3 is cut between the upper clamp plate 51 and the lower clamp plate 52 of the clamp device 50 by gripping the wire 3 at a portion between the nozzle 7 and the amateur 10. Is performed by laterally moving the clamp device 50.

After the completion of the first winding operation, the index cover 24 is raised again and the index 20 is turned 180 degrees to perform the second winding operation. Move the lined amateur 10 to the standby position, remove it from the index 20, and at the same time attach it to the index 20 in the standby position,
The plurality of armatures 10 that have been waiting to be wound on the second round are reversed and moved to the winding position. Therefore, a new winding is applied to the new armature 10 in the same procedure as described above. Line work is started.

When the index 20 rotates, the center former 30 retreats to the retreat position on the spindle 5 side to avoid interference with the index 20.
At this time, since the center former 30 is unstable only by keeping the balance with the center of gravity downward, the center concave portion 36 on the side of the center former 30 and the convex portion 37 on the side of the spindle 5 are fitted to each other to form the center. The former 30 and the spindle 5 are integrated to prevent the center former 30 from wobbling.

As described above, according to the present invention, the rack 4
By using the pinion 2 and the pinion 41, the amateur 10
The index mechanism that moves the winding position between the standby position and the winding position can be configured at low cost, and the position of each index can be adjusted by using the restricting plate 27, and the position of each amateur 10 can be adjusted by using the armature fixing cylinder 42. ,
Since each can be determined with high positioning accuracy,
High-precision winding can be performed on many amateurs 10 at the same time.

In the above embodiment, the winding is performed on the armature of the motor. However, the present invention is not limited to the winding machine for the armature of the motor. It is also applicable to machines.
