In the winding method related to this embodiment, first, the chuck opening and closing rod 18 is moved, and the front end cam 18a is pressed between the inclined cams 16a, 16b, thereby squeezing and expanding the chuck claws 15a, 15b, and then Turn on the chuck mechanism of the first spindle mechanism 10. Next, by using a workpiece supply mechanism (not shown in the figure), etc., one of the magnetic poles 3 is arranged along the rotation axis O, and the multi-pole armature 1 is positioned in the chuck claws 15a, 15b. Insert the multi-pole armature 1 between. The multi-pole armature 1 is maintained by the chuck claws 15a, 15b.

Then, the slide plate 20b is driven by the sliding movement motor 24b, so that the second spindle mechanism 20 is moved toward the first spindle mechanism 10. At this time, the support member 25 at the front end of the second main shaft 20a engages with the front end of the magnetic pole 3 of the multi-pole armature 1 and stops. Accordingly, the first spindle mechanism 10 and the second spindle mechanism 20 support both ends of the multi-pole armature 1.

Next, the wire feeder 31 of the wire supply unit 30 is moved by the three-axis moving mechanism 35 so that the front end of the wire W held by the clamp 34 of the wire feeder 31 faces the winding start position of the winding magnetic pole 3 In this embodiment, the movement is performed toward the front end side of the magnetic pole 3. Then, the wire W that starts to be wound is locked on the terminal portion (not shown) provided around the magnetic pole 3, and the wire clamp 34 is opened.

Then, by the third winding die moving mechanism 90, the opposing winding die 63 of the first spindle mechanism 10 is moved to the front end side of the magnetic pole 3 having the winding start end of the wire W. Specifically, as shown in FIG. 4A, the facing winding die 63 of the first spindle mechanism 10 is set from the front end 3a of the magnetic pole 3 (more specifically, the end face of the front end 3a on the side of the ring portion 2). The same applies to the above.) And in the rotation axis, it moves only at a position where the wire diameter is measured.

Furthermore, the central winding die and the lateral winding die 61 in the second spindle mechanism 20 are moved toward the first spindle mechanism 10 in the rotation axis direction. Specifically, as shown in FIG. 4A, the position of the central winding die 60 is that the position of the axis of rotation is slightly consistent with the front end 3a of the magnetic pole 3, wherein the central winding die 60 is positioned such that the claws at the front end 60b is slightly in contact with the front end 3a of the magnetic pole 3, or at least a small gap below the diameter of the wire to be approached. According to this, the center winding die 60 and the opposing winding die 63 are arranged with a gap of the diameter of the wire along the axis of rotation. As shown in Fig. 4B, the lateral winding die 61 enters the slot 4 of the multi-pole armature 1, and is positioned in such a way that the position of the leading end of the guide portion 61b along the axis of rotation is substantially the same as the leading end 3a of the magnetic pole 3 .

Next, the first main shaft 10a of the first main shaft mechanism 10 and the second main shaft 20a of the second main shaft mechanism 20 are synchronously rotated, and the magnetic poles 3 of the wound multi-pole armature 1 are rotated around the rotation axis O. In addition, as the first main shaft 10a and the second main shaft 20a rotate, the central winding die 60, the lateral winding die 61, and the opposite winding die 63 also rotate around the rotation axis O.

The wire W continuously fed from the wire feeding portion 31 is tensioned by a tension device (not shown in the figure) and is simultaneously supplied to the multi-pole armature 1. With the rotation of the magnetic pole 3 of the multi-pole armature 1, the wire W supplied to the multi-pole armature 1 contacts the inclined surface 60c of the central winding die 60, and is guided along the inclined surface 60c toward the magnetic pole 3 Lead to the axial and radial directions of the multi-pole armature 1 (arrows in Figure 4A).

Furthermore, the wire W is in contact with the guide portion 61b of the lateral winding die 61 along with the rotation of the magnetic pole 3, and is guided in the radial direction of the multi-pole armature 1 along the guide portion 61b (Fig. 4B Arrow). The lateral winding die 61 is a plate-shaped member arranged approximately perpendicular to the multi-pole armature 1, and the guide portion 61b is arranged along the slot 4 between the magnetic poles 3, and the slot 4 between the magnetic poles 3 is arranged in the multi-pole armature. The pole armature 1 extends in the radial direction. Therefore, when the wire W extending from the wire feeding portion 31 toward the magnetic pole 3 contacts the lateral winding die 61 with the rotation of the magnetic pole 3, the lateral winding die 61 moves along the axial direction of the multi-pole armature 1 In this way, the wire W is turned and guided to the magnetic pole 3. That is, the wire W is inserted into the slot 4 from the radial direction of the magnetic pole 3 of the multipole armature 1 while extending along the axial direction of the multipole armature 1 through the lateral winding die 61. Accordingly, the wire W guided to the surface of the magnetic pole 3 by the central winding die 60 and the lateral winding die 61 is guided to the wire W formed between the central winding die 60 and the opposing winding die 63 In the gap, and wound around the magnetic pole 3.

When the wire W is wound around the magnetic pole 3 only once, in the axis of rotation, the opposing winding die 63 moves toward the root side of the magnetic pole 3 (the side of the ring portion 2 of the magnetic pole 3) by only the amount of the wire diameter (refer to Figure 5A). Furthermore, the center winding die 60 is configured to move along the axial direction of the multi-pole armature 1, and move along the rotation axis toward the root side of the magnetic pole 3 by the amount of the wire diameter. The axial direction of the armature 1 is in contact with the wire W that goes around to the magnetic pole 3 only once, or is positioned at a position close to it with only a small gap. As a result, as shown in FIG. 5A, a gap of the diameter of the wire is formed between the opposing winding die 63 and the central winding die 60 along the axis of rotation. In addition, the lateral winding die 61 moves only the wire diameter amount to the root side of the magnetic pole 3 along the rotation axis (refer to FIG. 5B ). That is, the lateral winding die 61 moves to follow the movement of the central winding die 60 in the rotation axis. Thereby, with the rotation of the magnetic pole 3, the wire W is guided to the inclined surface 60c of the central winding die 60 and the guide portion 61b of the lateral winding die 61, and is guided to the central winding die 60 and the opposite The gap between the winding dies 63. The wire W of the second turn is wound on the magnetic pole 3.

Thereafter, each time the wire W is wound around the magnetic pole 3, in other words, the magnetic pole 3 is rotated one turn at the center of the rotation axis O, and the central winding die 60, the lateral winding die 61 and the opposite wire are wound. The die 63 moves toward the root side of the magnetic pole 3 by the amount of the wire diameter along the axis of rotation. Thereby, the wire W is guided to the magnetic pole 3 by the central winding die 60, the lateral winding die 61 and the opposite winding die 63, and the new wire W is wound on the magnetic pole 3 in turn and is The winding wires W are adjacent to each other. According to this, in a state where the side surfaces of the wire W are brought into contact with each other, the wire W can be sequentially wound to the magnetic pole 3.

When the wire W is wound to the root side of the magnetic pole 3, the opposing winding die 63 moves from the multi-pole armature 1 toward the away direction and along the axial direction of the multi-pole armature 1, and at the same time, moves toward the magnetic pole along the rotation axis. The tip of 3 moves only half the diameter of the wire (the hollow arrow in Figure 6A). As a result, as shown in FIG. 6A, the claw portion 60b of the opposing winding die 63 is slightly in contact with the first layer of wire W that has been wound or is positioned at a position close to it with a small gap. Furthermore, the central winding die 60 and the lateral winding die 61 move along the rotation axis and toward the root side of the magnetic pole 3 by only half the diameter of the wire (refer to FIGS. 6A and 6B). Between the central winding die 60 and the opposing winding die 63, a gap of the wire diameter is formed along the rotation axis. Therefore, as described above, with the rotation of the magnetic pole 3, the wire W is guided to the gap between the central winding die 60 and the opposing winding die 63, and the second layer is wound so as to overlap with the first layer. Layer the wire W of the first circle. The winding of the second layer is wound on the axis of rotation in such a way that it is offset from the winding of the first layer by only half the diameter of the wire.

After the first winding of the second layer, the opposing winding dies 63 respectively move in the direction away from the multi-pole armature 1 along the axial direction of the multi-pole armature 1, and at the same time move toward the magnetic pole 3 along the axis of rotation. The front end side of the wire moves, and the moving distance is the amount of the wire diameter. As a result, the opposing winding die 63 is slightly in contact with the wire W of the first turn of the second layer in the axial direction of the multipolar armature 1 or is positioned at a position close to it with a small gap. In addition, the center winding die 60 and the lateral winding die 61 move along the rotation axis direction toward the front end side of the magnetic pole 3 by only the wire diameter. Thereby, between the opposing winding die 63 and the central winding die 60, a gap of the wire diameter is formed again along the rotation axis. Therefore, as the magnetic pole 3 rotates, the wire W is guided to the gap between the central winding die 60 and the opposing winding die 63, and the wire W of the second layer and second turn is wound on the magnetic pole 3.

Thereafter, each time the wire W is wound to the magnetic pole 3, a pair of center winding dies 60, lateral winding dies 61 and a pair of opposed winding dies 63 are made to face the front end of the magnetic pole 3 along the axis of rotation. Move only the wire diameter amount on the side. Thus, the wire W is guided toward the magnetic pole 3 by the central winding die 60, the lateral winding die 61, and the opposing winding die 63, and the new wire W is sequentially wound around the magnetic pole 3 and connected with Wires W that have been wound are adjacent to each other.

When the wire W of the second layer is wound to the front end side of the magnetic pole 3, the opposing winding die 63 is moved along the rotation axis toward the root side of the magnetic pole 3 by only half the diameter of the wire (the hollow arrow in FIG. 7A) ). The center winding die 6 moves from the multi-pole armature 1 toward the away direction and along the axial direction of the multi-pole armature 1, while moving only one half of the wire diameter toward the root side of the magnetic pole 3 along the axis of rotation (Figure 7A Hollow arrow in). As a result, as shown in FIG. 7A, the claw portion 60b of the central winding die 60 is slightly in contact with or positioned close to the second layer of wire W which has been wound at the end. Furthermore, the lateral winding die 61 moves only half the diameter of the wire rod toward the root side of the magnetic pole 3 along the axis of rotation (refer to FIG. 7B ). Between the central winding die 60 and the opposite winding die 63, a gap of the wire diameter is formed along the rotation axis. Therefore, as described above, with the rotation of the magnetic pole 3, the wire W is guided into the gap between the central winding die 60 and the opposing winding die 63, and the third layer is superimposed on the second layer. The winding of the wire W in one circle. The winding of the third layer is wound on the axis of rotation in such a way that it is offset from the winding of the second layer by only one half of the diameter of the wire.

After that, by the same operation method as the winding of the first layer, the winding after the second turn of the third layer is performed.

By repeatedly performing the above-mentioned operations, only the wire W with a specified amount of winding layer is wound to the magnetic pole 3. When the winding is finished, stop the rotation of the first spindle 10a of the first spindle mechanism 10 and the second spindle 20a of the second spindle mechanism 20, and the wire W at the end of the winding faces the end set on the multipolar armature 1 Winding (not shown in the figure). The opposing winding die 63 of the first spindle mechanism 10, the center winding die 60 of the second spindle mechanism 20, and the lateral winding die 61 are each retracted so as to be separated from the multipolar armature 1 along the rotation axis.

Even during this period, a desired tension is applied to the wire W sent from the wire supply part 30 by the tension device, thereby preventing the wire W from loosening when wound toward the end. Then, the feeding of the wire W is stopped by the clamp 34 of the wire feeding part 31, and the wire feeding part 31 is returned to the initial position. Accordingly, winding to one magnetic pole 3 is completed.

When the winding to one magnetic pole 3 is completed, the indexing shaft 53 of the indexing mechanism 50 is raised to fit into the center hole 2a of the multi-pole armature 1. In this state, the second spindle mechanism 20 retreats in the rotation axis, and the chuck mechanism 15 of the first spindle mechanism 10 is opened. Furthermore, the multi-pole armature 1 is rotated by the indexing motor 51, and the newly wound magnetic poles 3 are arranged along the rotation axis. In this state, the chuck mechanism 15 maintains the multi-pole armature 1 again, causes the second spindle mechanism 20 to advance toward the multi-pole armature 1, and engages the support member 25 to the magnetic pole 3 of the multi-pole armature 1. After that, the index axis 53 of the index mechanism 50 is lowered to the standby position. Accordingly, when it is in the standby state again, the wire W is wound around the new magnetic pole 3 in the same manner as described above.

When the winding is completed to all the magnetic poles 3, the wire W at the end of the winding is maintained by the wire clip 34 of the wire feeding part 31, and the wire W between the wire clip 34 and the multi-pole armature 1 is cut by the cutting piece 43 . At the same time, the second spindle mechanism 20 is retracted, the chuck mechanism 15 of the first spindle mechanism 10 is opened, and the multi-pole armature 1 that has been wound is removed. Through the above steps, winding to the magnetic pole 3 of the multi-pole armature 1 is completed.

According to the above embodiment, the following effects can be achieved.

According to this embodiment, with the lateral winding die 61, the wire W is turned along the axial direction of the multi-pole armature 1, and the wire W is directed toward the groove 4 between the magnetic poles 3 along the multi-pole armature. 1 is guided in the radial direction. Accordingly, in the state along the axial direction of the multi-pole armature 1, the wire W is inserted into the slot 4 from the radial direction, and the magnetic pole 3 adjacent to the winding magnetic pole 3 can be prevented from contacting the wire W. Therefore, it is possible to stably wind the plurality of magnetic poles 3 arranged in the circumferential direction. In addition, since the contact between the wire W and the adjacent magnetic pole 3 is suppressed, even when the number of magnetic poles 3 is large and the interval between adjacent magnetic poles 3 is narrow, the main shaft winding can be stably performed with respect to the magnetic pole 3.

Furthermore, the lateral winding die 61 can simultaneously move back and forth in the axis of rotation along with the pair of center winding dies 60. Therefore, during the winding process, the winding can be more stably and accurately guided to the position of the winding wire W, more specifically, the position adjacent to the wire W that has been wound. Therefore, the twisting and breaking of the wire W in the winding can be suppressed, and the gap generated between the wire W being wound can be suppressed, thereby increasing the space factor.

Next, a modification of this embodiment will be explained.

In the above-mentioned embodiment, by the second winding die moving mechanism 80, the lateral winding die 61 can move back and forth in the axis of rotation. In contrast, a mechanism for moving the lateral winding die 61 may not be provided, and the lateral winding die 61 may also be configured such that, with respect to the second spindle 20a of the second spindle mechanism 20, the lateral winding die 61 cannot Relative movement. That is, only in the case where the lateral winding die 61 and the second main shaft 20a are moved integrally by the sliding mechanism 24, it can also be configured to move to the rotation axis.

Furthermore, in the above-mentioned embodiment, the single lateral winding die 61 is arranged on one side of the central winding die 60 in the circumferential direction. In contrast, a pair of lateral winding dies 61 can also be provided at a position where the central winding die 60 is clamped in the circumferential direction of the multi-pole armature 1. In other words, lateral winding dies 61 may also be provided on both sides of the central winding die 60 in the circumferential direction, respectively.

Furthermore, in the above-mentioned embodiment, the first spindle mechanism 10 includes a pair of opposed winding dies 63. On the other hand, the facing winding die 63 is not essential, and the first spindle mechanism 10 may not include a pair of facing winding dies 63.

Hereinafter, the structure, function, and effect of the embodiment of the present invention will be comprehensively explained.

The present invention provides a winding device 100 for winding a wire W to the magnetic poles 3 of a multi-pole armature 1. The magnetic poles 3 of the multi-pole armature 1 extend radially and are arranged in parallel in the circumferential direction. Among them, The winding device 100 includes a first spindle mechanism 10 that supports the multi-pole armature 1 and rotates the magnetic poles 3 arranged along the rotation axis O around the rotation axis O; the second spindle mechanism 20 and the first spindle mechanism 10 rotates synchronously, is configured to be opposite to the first spindle mechanism 10, and together with the first spindle mechanism 10 supports the multi-pole armature 1; the wire supply part 30 supplies the wire W to the multi-pole armature 1; a pair of center windings The mold 60 guides the wire W toward the magnetic pole 3; the lateral winding mold 61 guides the wire W toward the magnetic pole 3. The pair of center winding dies 60 are arranged to face each other so that the magnetic pole 3 is sandwiched by the axial direction of the multi-pole armature 1. The lateral winding die 61 directs the wire W toward the groove 4 formed between the magnetic poles 3 and guides it along the radial direction of the multi-pole armature 1.

In addition, the present invention provides a winding method for winding the wire W to the magnetic pole 3 of the multi-pole armature 1, and the magnetic pole 3 of the multi-pole armature 1 is extended radially, and a plurality of them are arranged side by side in the circumferential direction. , Wherein the magnetic pole 3 rotates with the rotation axis O as the center, and a pair of central winding dies 60 are arranged such that the magnetic pole 3 is sandwiched by the axial direction of the multi-pole armature 1, and the wire W is directed While the magnetic pole 3 is being guided, the wire W is directed toward the groove 4 formed between the magnetic poles 3 and guided along the radial direction of the multi-pole armature 1 by the lateral winding die 61, and the wire W is wound to Around magnetic pole 3.

In these structures, the wire W is directed toward the groove 4 formed between the magnetic poles 3 and guided along the radial direction of the multi-pole armature 1 by the lateral winding die 61. Thereby, since the wire W is inserted into the groove 4 from the radial direction, contact with the wire W adjacent to the magnetic pole 3 can be suppressed. Therefore, a plurality of magnetic poles 3 arranged in the circumferential direction can be wound stably.

In addition, the winding device 100 is further provided with a first winding die moving mechanism 70 to move the lateral winding die 61 forward and backward relative to the groove 4.

In this structure, since the lateral winding die 61 can advance and retreat relative to the groove 4, the wound wire W can be guided to a desired position with better accuracy. Thereby, in addition to suppressing the twisting or breaking of the wound wire W, at the same time, it suppresses the generation of a gap between the wound wire W, thereby increasing the space factor.
