Abstract

PURPOSE:To make it possible to apply a same winder on various split stator cores having different diameters by regulating the distance between the center P of index of the slit stator core and the center Q of rocking. CONSTITUTION:In a stator core 11 held by a holder 35 on a second turn table 64, the second turn table 64 rotates around the axis P (center of index) of a shaft 60 to position the winding line of flyer with respect to a specific slot 13. Furthermore, a first turn table 51 reciprocates during winding operation with the axis Q (center of rocking) of a rotary shaft 44 as a center and thereby the stator core 11 rocks with the point Q, which is close to the inlet of the slot 13 to be applied with winding, as a center. In such a manner, winding is applied sequentially in each slot 13 of the split stator core 11. When a knob 57 is rotated, a sliding board 52 slides against the first turn table 51 through a screw moving mechanism. Consequently, the distance between the axis Q of the rotary shaft 44 and the axis P of the shaft 60 varies.

Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a winding device for winding a coil around a semicircular arc-shaped divided stator core formed by dividing an annular stator core into two.

"Conventional technology" In recent years, there has been a strong demand for electric motors to be smaller and lighter, as well as thinner.The stator core, which constitutes the main part of the electric motor, is divided into two parts, and a yoke part for each slot of the iron core is created. Electric motors are attracting attention because they have toroidal windings perpendicular to the motor to promote thinness of the motor, as well as to reduce material costs and increase efficiency. As a winding device for such a split stator core, for example, Japanese Patent Application Laid-Open No. 60-245453 discloses a device that rotates the split stator core around the center to align the flyer winding line with a predetermined slot. However, a device has been disclosed in which the winding is performed while the split stator core is oscillated about the entrance portion of the slot. With this device,
There is an advantage that the electric wire can be evenly wound around the yoke part of the slot.

5 to 9 show an example of a winding device for the split stator core as described above.

As shown in FIGS. 5 to 7, this winding device is provided with a first turntable 33 and a second turntable 34 via a support shaft 32 erected on a base 31. ing. A holder 35 is erected on the second turntable 34, and the split stator core 11 is removably held in the holder 35 with its arcuate surface horizontal. Holder 3
5, a rotating shaft 38 supported by a frame 36
A one-rotation shaft 38 on which a fryer 39 is installed is rotationally driven by a motor (not shown). Further, the rotating shaft 38 is movable in the axial direction, and is adapted to push out the flyer 39 to a predetermined position during winding.

As shown in FIG. 8.9, the second turntable 34 is rotated about a point P at the center of the split stator core 11 held by the holder 35 by a drive mechanism (not shown). This allows each slot 13 of the split stator core 11 to be connected to the winding line of the flyer 39! It is designed to be aligned sequentially.

On the other hand, the first turntable 33 is configured to swing at a predetermined angle about a point Q near the entrance of the slot 13 where the winding of the split stator core 11 is performed by a drive mechanism (not shown). In this case, the winding operation using the device in which the turntable 34i3 and the holder 35 also swing as the turntable 33 swings is performed as follows.

First, the winding jigs 21 are attached to the teeth 12 of the divided stator core 11, respectively, and then the 1-divided stator core 11 is attached to the holder 35. When the device is operated in this state, the second turntable 34 rotates around point P, and the winding line β of the flyer 39 is aligned with the predetermined slot 13 of the one-segment stator core 11. Once alignment is achieved, rotation of the turntable 34 is stopped until the winding in that slot 13 is completed.

Next, the first turntable 33 begins to swing at a predetermined angle θ about a point Q near the entrance of the slot 13. Therefore, together with the first turntable 33, the second turntable 34, the holder 35i3, and the split stator core 1
1 also oscillates. At the same time, a motor (not shown) is activated, and the fryer 39 begins to rotate via the rotating shaft 38.
Winding work begins.

Since the split stator core 11 is swinging, the electric wires 47 are arranged in a line on the yoke section at the bottom of the slot 13, and are further layered on top of the yoke in a line.

In this way, when the winding in the predetermined slot 13 is completed, the rotation of the flyer 39 is stopped, and at the same time, the swinging of the first turntable 33 about the point Q is also stopped.

Then, the second turntable 34 rotates again, and the adjacent slots 13 of the divided stator core
2, and the same winding operation as above is repeated again.

"Problems to be Solved by the Invention" The conventional winding device for a split stator core described above has an index center point for aligning the winding line β of the flyer 39 with a predetermined slot 13 of the split stator core 11. P and
The distance from the swinging center point Q, which swings the split stator core 11 around the entrance of the slot 13 where the winding is performed, is as follows:
It had become fixed. However, the distance between the index center point P and the swing center point Q may need to be changed depending on the type of split stator core, the thickness of the electric wire, the number of windings, etc.

That is, the distance between the index center point P and the swing center point Q naturally changes when the diameter of the split stator core 11 changes. Furthermore, even when winding is performed on the split stator core 11 having the same diameter, in order to align the electric wires 47 with the yoke at the bottom of the slot 13 and wind them as densely as possible, the swing center is located near the entrance of the slot 13. It may be necessary to delicately adjust the position of point Q.

Therefore, an object of the present invention is to make it possible to change the distance between the integral center point ゛P and the swing center point Q, so that the type of split stator core, the thickness of the electric wire, the number of windings, etc. can be changed. Another object of the present invention is to provide a winding device for a split stator core that can be handled using the same device.

"Means for Solving the Problem" In order to achieve the above object, a winding device for a split stator core according to the present invention is provided.

"Function" In the winding device of the present invention, the second turntable (6
The axis of the support shaft (60) of 4) forms the index center point P, and the axis of rotation (44) of the first turntable 151)
) forms the swing center point Q, and the split stator core (11) held in the holder (35) on the second turntable (64) is rotated by the second turntable (64). By moving the flyer (39), the winding line β of the flyer (39) is aligned with the predetermined slot (13). moreover,
During the winding operation, as the first turntable (51) reciprocates, the divided stator core 1111 swings around a point Q near the entrance of the slot (13) where the winding is applied. . In this way, each slot +131' of the split stator core (11) can be successively wound.

By the way, in the present invention, the screw moving mechanism allows

0) changes. As mentioned above, the support shaft (60
), the index center point P is formed.

Since the axial center of the rotating shaft (44) forms the swing center point Q, the distance between the index center point P and the swing center point Q can be adjusted by the above operation.

For this reason, it is possible to wind wires on split stator cores with different diameters using the same device, and it is also possible to wind wires on split stator cores with different diameters.
It is possible to finely adjust the position of the swing center point Q so that the wires are aligned and densely wound within the slots (13) of the wires 111.

One example includes a male screw (56) which is threadedly inserted into the female screw member (54) and whose one end is pivotally attached to the slide plate (52). According to this, by changing the degree of engagement between the female thread member (54) and the male thread (56), the male thread (56) moves in the axial direction, so that the male thread (56) is connected to one end of the male thread (56). The slide plate (52) slides. However, various other structures can be adopted as the screw moving mechanism.

A rotary shaft 44 is rotatably inserted and supported in the sleeve 43 via a bearing 45.The axial center of the one-rotation shaft 44 forms the aforementioned swing center point Q. Referring also to FIG. A boss portion 46a of a sector gear 46 is fixed to the lower end of the shaft 44. In relation to this sector gear 46, a servo motor 40 is mounted on the bottom surface of the board 42.
is attached via a holder 48. A gear 50 is attached to the drive shaft 49 of the servo motor 40, and this gear 50 is connected to the upper 8 [l! It meshes with the sector gear 46.

Therefore, the operation of the servo motor 40 causes the drive shaft 49 to
The gear 50 rotates, and the rotary shaft 44 rotates via the sector gear 46.

A flange 44a is formed at the upper end of the rotating shaft 44, and the first turntable 51 is fixed to this flange 44a with bolts. On the top surface of the first turntable 51,
A slide plate 52 is slidably attached as shown by arrow A in FIG. 1 by fitting into a guide groove (not shown). If we look at Figure 4 together, we can see that the first turntable 5
A plate 53 is fixed to one side edge of 1 with bolts, and this plate 5
A female screw member 54 is attached to 3. Female screw member 5
A scale 55 is engraved along the axial direction on the outer periphery of 4. A male screw 56 is screwed into the female screw member 54 and inserted through the plate 53. The tip of the male screw 56 is pivotally attached to the side edge 52a of the slide plate 52.
A knob 57 is attached to the base end of 6. Therefore, when the knob 57 is rotated, the male screw 56 rotates, and since the male screw 56 is screwed into the female screw member 54, the male screw 56 rotates.
moves in the axial direction. At the same time, the slide plate 52 connected to the tip of the male screw 56 moves in the direction of the arrow in the figure.

A support shaft 60 is erected on the upper surface of the slide plate 52, with a flange portion 60a at the lower end thereof being fixed with bolts. A sleeve 62 is attached to the outer periphery of the support shaft 60 via a bearing 61.
is rotatably mounted. A ring-shaped gear 63 is fixed to the flange portion 62a of the sleeve 62 with bolts. Furthermore, a second turntable 64 is attached to the upper surface of this gear 63 with bolts. The second turntable 64 is provided with a portion 64a in which the holder 35 of the split stator core 11 is installed. A spacer 66 and a support plate 67 are extended by bolts 65 on the side edge of the slide plate 52 opposite to the part connected to the male screw 56, and a servo motor 69 connects the support plate 67 with a flange portion 68. The installation has been fixed. The servo motor 69 is attached to the lower surface of the support plate 67 and inserted into the notch 42a of the substrate 42. And servo motor 6
The gear 72 attached to the drive shaft 71 of No. 9 is the upper Me gear 63.
It fits perfectly. Therefore, the servo motor 69 operates and the drive shaft 71. When the gear 72 rotates, the gear 63 meshing with the gear 72 rotates, and the second turntable 64 rotates together with it. In addition, the support shaft 6
The axis of ◎ forms the index center P.

Referring also to FIG. 2, a holder 35 for the split stator core 11 is provided upright on the upper surface of the second turntable 64. As shown in FIG. Similar to the conventional example described above, the split stator core 11 is held parallel to the second turntable 64 by the holder 35.

5.76 is installed. The proximity sensors 75 and 76 detect when the second turntable 64 rotates and the arm 74 approaches, and detect this position as the second turntable 6.
As a reference point for the rotation of 4, an operating signal is sent to the servo motor 69 via a control device (not shown). Further, stoppers 77 and 78 are installed on the board 42, and these stoppers 77 and 78 come into contact with protrusions (not shown) protruding from the lower surface of the gear 63, thereby stopping the gear 63 and the second turntable 64. Regulate the rotation range.

Also referring to Figure 2.4, slidable arms 81, 82 are attached. In this connection, a pair of proximity sensors 83, 84 are installed on the substrate 42. Proximity sensor 83 detects when arm 81 approaches, and proximity sensor 84 detects when arm 82 approaches. The swing range of the first turntable 51 and slide plate 52 around the swing center Q is restricted to the range of rotation detected by these proximity sensors 83 and 84.

That is, based on the detection signals of the proximity sensors 83 and 84,
The operation of the servo motor 69 is controlled.

Note that structures such as the flyer 39 adjacent to the rotational support structure of the split stator core 11 described above are similar to those of the fifth to ninth structures described above.
Since this is the same as the conventional device shown in the figure, its explanation will be omitted.

Next, the operation of the winding device for this split stator core will be explained. In addition, in order to make the explanation easier to understand,
Regarding the parts omitted from illustration in Figure 4, parts 5 to 9
Let us borrow the numbers of the devices shown in the figure.

After the winding jig 21 is attached to the teeth 12 of the split stator core 11 in advance, the split stator core 11 is held in a holder 35 erected on the second turntable 64, and then
When the winding device is operated with the installation of the 0-segment stator core 11 supported in parallel to The second turntable 64 rotates around the index center point P to align the first slot 13 of the split stator core 11 to be wound with the winding line β. In this state, the flyer 39 rotates and the winding for the first slot 13 is exposed.

When this winding starts, the servo motor 40 is operated to rotate the rotary shaft 44 via the drive shaft 49, gear 50i5, and sex gear 46, and at the same time, the first turntable 5
1 and the slide plate 52 move the swing center point Q set near the entrance of the slot 130 of the split stator core 11 to the center IC.
The bow rotates. In this case, the aforementioned proximity sensor 83.8
4 sends a signal to switch the rotation direction of the servo motor 40, so the first turntable 51 and the slide plate 52 swing at a predetermined angle about the swing center point Q. Further, since the second turntable 64 is supported by a support shaft 60 erected on the slide plate 52, the second turntable 64 similarly swings, and as a result, the holder 35
The split stator core 11 supported by the split stator core 11 swings around a point Q near the entrance of the slot 13 in which the wire is wound. Therefore, the electric wires 47 are arranged in a line on the yoke portion at the bottom of the slot 13 of the split stator core 11, and are further layered on top of the yoke in a line.

When the first slot 13 has been wound a predetermined number of times in this manner, the flyer 39 is temporarily stopped, and the servo motor 40 is also temporarily stopped. In this condition.

The servo motor 69 operates again and the drive shaft 71 and gear 72
The second turntable 64 rotates around the index center point P via the gear 63, and the next slot 13 of the divided stator core 11 to be wound is set to the winding line! Aligned to . Then, by repeating the above operations, windings are sequentially applied to the slots 13 of the single-segment stator core 11. In this way, when all the slots 13 are wound, the winding device stops, and the work of replacing the divided stator core 11 with a new divided stator core 11 is performed.
Winding the wires to the slots 13 of No. 1 does not require winding all the slots 13 in one operation. For example, attaching the split stator core 11 to the holder 35 can be done in two operations by changing the direction. Winding may also be applied.

By the way, when the diameter of the divided stator core 11 is changed, the distance between the index center point P and the swing center point Q must be changed according to the diameter of the divided stator core 11. In addition, the setting of the swing center point is the split stator core 11.
The split stator core 11 is slightly changed in the vicinity of the entrance of the slot 13 without damaging the electric wire 47.
It is necessary to experimentally find the best position in which the electric wires 47 can be aligned and densely arranged in the slots 13. In such a case, in this winding device, the distance between the index center point P and the swing center point Q can be freely changed by turning the knob 57.

That is, when the knob 57 is rotated, the male screw 56 rotates, and since the male screw 56 is screwed into the female screw member 54,
The male screw 56 moves in the axial direction. At the same time, male screw 5
A slide plate 52 connected to the tip of 6 moves in the six directions indicated by arrows in the figure. As a result, the index center point P, which is the axis of the support shaft 60 erected on the slide plate 52, and the substrate 4
The distance from the swing center point Q, which is the axis of the rotating shaft 44 supported by the rotating shaft 44 supported by the rotating shaft 44, can be changed. Note that the amount of movement of the male screw 56 due to the rotation of the knob 57 can be measured by the scale 55 carved on the outer periphery of the female screw member 54, so that delicate adjustment is possible.

Further, by changing the index angle of the servo motor 69, it is possible to freely adapt to split stator cores 11 having different numbers of slots 13.

"Effects of the Invention" As explained above, according to the winding device of the present invention, the distance between the index center point P and the swing center point Q can be changed, so that it is possible to change the distance between the index center point P and the swing center point Q. It can accommodate split stator cores with different diameters. In addition, by slightly changing the distance between the index center point P and the swing center point q, the swing center point Q is adjusted so that the electric wires are aligned and densely wound in the slots of the split stator core. It can be set in the best position. Furthermore, the adjustment work of the swing center point Q can be performed easily and quickly.
