SUMMARY OF THE INVENTION A method according to the present invention comprises a yoke portion which, when combined, forms part of an annular yoke, a core portion having one end connected to the yoke portion, and a second end portion connected to the yoke portion. A split core support device having a split core support having a linked magnetic pole piece and supporting a split core having a curved inner surface connected to the side surface of the core portion of the yoke, and a nozzle for supplying a winding conductor And a winding conductor supplying device for supplying a winding conductor to the split core, and performing relative movement between the split core support base and the nozzle to wind the winding conductor around the iron core portion. The winding method of the split core to be mounted is to be improved.

In the present invention, when the winding conductor is wound around the side surface of the iron core portion (the lamination surface of the steel plates constituting the divided core or the surface along the lamination direction of the steel plates), the nozzle is arranged so as not to interfere with the divided core. Determine the angle of the nozzle with respect to a center plane passing through the centers of the yoke, iron core and pole piece (so that the nozzle does not hit a part of the split core and the nozzle does not move). And in this invention, a winding conductor is wound around an iron core part so that the space formed between a yoke part and a pole piece part may be filled, and a winding part is formed. It is needless to say that an insulating member called a slot insulator for electrical insulation between the split core and the winding portion may be interposed between the surface of the split core and the winding portion. Here, "to fill the space" refers to the winding between the yoke and the pole piece, including the space adjacent to the intersection of the side surface of the iron core and the inner surface of the yoke. This means that the winding conductor is wound so as not to leave a large space where no conductor exists, and the space is filled with the winding conductor as much as possible. If this space is completely filled, the space factor will be the highest, but it goes without saying that the winding part formed by winding the required number of turns does not have to completely fill this space.

The angle of the nozzle is set only when the winding conductor is wound around at least the side surface of the iron core. This is because the nozzle does not interfere with the split core when the winding conductor is wound around the end surface of the iron core (the surface located on both sides in the stacking direction of the steel sheet). That's why.

According to the present invention, the winding conductor is wound while appropriately changing the angle of the nozzle with respect to the center plane of the split core so that the nozzle does not interfere with the split core. The winding conductor can be wound around the iron core so that the winding conductor also exists in the space formed between the curved inner surface of the iron part. As a result, the space factor can be greatly increased as compared with the related art. In addition, the winding conductor can be wound in a state where the winding conductor is present in the space formed between the side surface of the iron core portion and the curved inner surface of the yoke portion. The occurrence of winding collapse during the turning operation can be prevented. Therefore, it is possible to arrange and wind the winding conductor.

The method of the present invention can be applied not only to a case where a winding portion is formed on one split core, but also to a case where a winding portion is simultaneously formed on a plurality of split cores.
In this case, in particular, a plurality of divided cores necessary for constituting one stator are supported in a row on a divided core support base, and a plurality of nozzles are provided in a winding conductor supply device, and a plurality of phased cores are simultaneously provided. The winding conductor is wound around each of the plurality of divided cores, and the winding portions are simultaneously formed on the plurality of divided cores for the plurality of phases. The winding conductor is wound around each of the plurality of divided cores, and the winding portions are simultaneously formed on the plurality of divided cores for the next plurality of phases, and all of the plurality of divided cores necessary to constitute one stator If the above operation is repeated until the winding portion is formed, the winding portion can be continuously formed on each split core without forming a connection portion on the crossover connecting the winding portions of the split cores of each phase. .

In forming the winding portion, one or both of the nozzle and the split core support may be moved to generate a relative rotational movement between the nozzle and the split core. However, when the nozzle is relatively
If it is not necessary to change the angle of the nozzle during rotation, moving the split core support to obtain relative rotation allows the winding conductor to be wound faster. When it is necessary to change the angle of the nozzle while the nozzle makes one rotation around the outer circumference of the split core, it is faster to move both the nozzle and the split support to obtain the relative rotation. Winding conductor can be wound.

The timing for changing and setting the angle of the nozzle is arbitrary. However, when the winding operation is performed smoothly and quickly, the relative angle to the divided core along the side surface of the iron core of the divided core is obtained. It is preferable that the setting of the angle is not changed when the nozzle moves, and the setting of the angle is changed when the nozzle moves relative to the split core along the end face of the core portion of the split core. This is because while the nozzle moves relative to the split core along the end face of the core of the split core, there is no need to maintain the nozzle at a specific angle, and the nozzle may interfere with the split core. Because there is no. Therefore, at this time, if the setting for changing the angle of the nozzle is performed, the operation can be quickly and smoothly shifted to the operation of winding the winding conductor around the side surface of the iron core portion.

The winding method or winding method of the winding conductor for preventing the occurrence of winding collapse (the phenomenon that the wound winding conductor is shifted) when winding the winding conductor is arbitrary. For example, as an example, firstly, a winding conductor is wound around the core along the core with the portion where the side surface of the core and the inner surface of the yoke intersect or in the vicinity thereof as the winding start position, and then completely wound. A layer is formed. Next, the winding conductor is wound on the complete winding layer so that the length of the winding layer in the direction along the iron core portion becomes shorter toward the outside to form the yoke-side winding layer. The length of the wound layer in the direction along the iron core portion of the yoke-side wound layer may be shorter as it goes outward, and the order of formation or the method of formation is arbitrary. Then, the winding conductor is wound along the iron core portion on the portion not covered by the yoke portion side winding layer on the complete winding layer side, and the winding layer is completed by completing the winding layer. . The winding procedure or the winding method of the winding conductor at this time is also arbitrary, but it is preferable that the winding is performed so that the winding conductors constituting the winding layer are aligned. According to the above-mentioned winding order or winding method, since the yoke portion side winding layer is formed first and the space portion on the yoke portion side is filled with the winding conductor, winding collapse is unlikely to occur. There are advantages. Also, in the winding work of the winding conductor after winding the yoke part side winding layer, if the yoke part side winding layer is formed to the extent that it is not necessary to change and set the nozzle angle, the winding The rotation speed can be increased.

A winding conductor is wound around the core along the core to form a first completely wound layer, with a region where the side surface of the core and the inner surface of the yoke intersect as a winding start region, The next complete winding layer may be formed by winding the winding conductor around the core portion along the core portion on the next first complete winding layer to form the next full winding layer, and thereafter, the winding portion may be completed. Of course.

An apparatus for carrying out the method of the present invention comprises a yoke portion which, when combined, forms a part of an annular yoke, a core portion having one end connected to the yoke portion, and another end portion of the core portion. Supplying a split core support device having a split core supporter that supports one or more split cores having a curved inner surface connected to the side surface of the core portion of the yoke portion and having a connected pole piece portion, and a winding conductor A winding conductor supply device having one or more nozzles for supplying a winding conductor to a split core; and a relative movement between the split core support base and the one or more nozzles, to the iron core portion. It can be composed of a split core supporting device and a controller for controlling the winding conductor supply device so as to wind the winding conductor. The split core support device includes a support base moving mechanism for moving the split core support base in the X and Y directions. Further, the winding conductor supply device includes a nozzle support for rotatably supporting one or more nozzles, a nozzle moving mechanism for moving the nozzle support in the Z direction and the X direction, and a rotation shaft extending in the Y direction. And a nozzle rotating mechanism for rotating one or more nozzles within a predetermined angle range around the center. Where in the X direction,
The Y direction and the Z direction constitute a three-dimensional coordinate axis having an angle of 90 degrees between each other. By using such an apparatus, the method of the present invention can be performed with a simple configuration.

In the case where the winding portions are simultaneously formed on the plurality of split cores, the plurality of split cores are arranged on the split core support base in the X direction, and the plurality of split cores are oriented such that the end faces of the core portions in the stacking direction face the Y direction. A holding jig for holding the core is provided. Then, a plurality of nozzles may be supported by the nozzle support portion of the winding conductor supply device so as to be arranged in the X direction.

The configuration of the controller is arbitrary, but the controller
When winding the winding conductor around the side surface of the core, the nozzle is wound so as to determine the angle of the nozzle with respect to the center plane passing through the center of the yoke, iron core and pole piece so that the nozzle does not interfere with the split core. Controlling the nozzle rotation mechanism of the conductor supply device,
The operation required to wind the winding conductor around the iron core so as to fill the space formed between the yoke part and the pole piece is performed by the support base moving mechanism of the split core support device and the winding conductor supply. The method of the present invention can be easily implemented if the apparatus is configured to control the nozzle moving mechanism and the nozzle rotating mechanism of the apparatus.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1A is a diagram for explaining the basic principle of the method of the present invention, and FIG. 1B is a diagram schematically showing a state of a winding formed by the method of the present invention. The split core 1 is configured by laminating a plurality of silicon steel sheets punched into the same shape, and welding the laminated surfaces or joining the silicon steel plates having an adhesive applied to the laminated surfaces. The split core is composed of a yoke portion 1a which forms a part of an annular yoke when combined,
core 1b and core 1b connected (connected) to a
And a pole piece 1c connected to the other end of the pole piece. An inner surface 1d of the yoke portion 1a connected to the side surface of the iron core portion 1b is curved in an arc shape. The inner surface 1e of the pole piece 1c is also curved in a substantially arc shape. Although not shown, the outer surface of the core portion 1b and the inner surface 1 of the yoke portion 1a are formed to form the winding portion.
d and the inner surface 1e of the pole piece 1c are covered with an insulating member called a slot insulator. The split core 1 is supported by a split core support of a split core support device (not shown).

Reference numeral 2 denotes a nozzle for supplying a winding conductor 3;
The nozzle 2 is supported by a winding conductor supply device (not shown) that supplies a winding conductor to the split core 1. Although FIG. 1A shows a plurality of nozzles 2, this is for indicating that the angle of the nozzles 2 can be displaced. One nozzle 2 is used. In order to form the winding part 4, a relative movement (a movement in which the nozzle 2 relatively rotates around the iron core 1 b of the divided core 1) between the divided core support (not shown) and the nozzle 2 is performed. Then, the winding conductor 3 is wound around the core portion 1b.

According to the present invention, the nozzle 2 is arranged at an arbitrary angle θ with respect to a center plane (an imaginary plane extending in a direction perpendicular to the plane of the drawing) 5 passing through the centers of the yoke part 1a, the iron core part 1b, and the pole piece part 1c. And the winding conductor 3 is wound around the iron core 1b. Specifically, the side surface (laminated surface of the silicon steel plate) 1f of the iron core 1b
When the winding conductor is wound around 1 and 1f2, the angle θ of the nozzle with respect to the center plane 5 is determined so that the nozzle 2 does not interfere with the split core 1, and the angle between the yoke 1a and the pole piece 1c is set. The winding conductor 4 is formed by winding the winding conductor 3 around the iron core 1b so as to fill the space S formed. As can be seen from this figure, in order to wind the winding conductor 3 around the side surface 1f1 and the side surface 1f2 of the iron core 1b, it is necessary to change the angle θ of the nozzle 2. This angle change is performed by changing the nozzle 2 to the end face of the iron core 1b (the face located on both sides in the stacking direction of the steel sheet)
It may be performed when the winding conductor is wound around 1 g. When winding the winding conductor 3 around the end face 1g of the iron core 1b, if the distance between the nozzle 2 and the end face 1g is sufficiently widened, the nozzle 2 will interfere with the split core 1 (collision). Since the nozzle 2 does not stop moving together), the angle of the nozzle at this time is arbitrary.

In FIG. 1 (A), the tip of the nozzle 2 is inserted to the inside of the space S to a considerable extent. However, since the winding conductor 3 extends in the space S, the tip of the nozzle 2 is Even if the nozzle 2 is not inserted deeply, the winding conductor can be arranged deep inside the space S if the angle θ of the nozzle 2 is set to a predetermined angle.

FIGS. 2 (1) to 2 (8) are process diagrams showing a part of an initial process of winding a winding around the split core 1. FIG. In each of FIGS. 2 (1) to 2 (8), the diagram shown on the left shows the relationship between the split core 1 and the nozzle 2 when the split core 1 is viewed from the side surface 1f1 (laminated surface). . FIG. 2
In each of the drawings (1) to (8), the drawings on the right side show the relationship between the split core 1 and the nozzle 2 when the split core 1 is viewed from the end face 1g side. In the following description, it is assumed that the nozzle 2 rotates around the divided core 1 for easy understanding.

First, the end of the winding conductor 3 is locked to a conductor locking portion of a core support (not shown), and winding of the winding is started.
As shown in FIGS. 2 (1) and 2 (2), when winding the winding conductor 3 around the side surface 1f2 of the iron core 1b,
The winding operation is performed with the nozzle 2 inclined to the right by θ1 with respect to the center plane 5. After winding the winding conductor 3 around the side surface 1f2 of the iron core 1b, as shown in FIG. 2 (3), the nozzle 2 is moved to a position away from the end face 1g2 of the iron core 1b to some extent. 3) As shown in FIG. 2 (5), the nozzle 2 is rotated by .theta.1 + .theta.2 degrees during the operation of winding the winding conductor 3 around the end face 1g2 of the iron core 1b. Usually, θ1 = θ2.

The angle θ between the nozzle 2 and the center plane 5
2 (5) to 2 (7), the winding conductor 3 is wound around the side surface 1f1 of the iron core portion 1b while maintaining the value 2 as shown in FIG. When the nozzle 2 exceeds the end face 1g1 of the iron core 1b, the nozzle 2 is moved to a position somewhat away from the end face 1g1 of the iron core 1b as shown in FIG.
2 (5), during operation of winding the winding conductor 3 around the end face 1g1 of the iron core 1b, the nozzle 2
After turning by + θ2 degrees, the state returns to the state shown in FIG. Thereafter, this operation is repeated. As shown in FIG. 2, the winding conductor is wound while changing the angle between the nozzle 2 and the center plane 5 only when the nozzle 2 interferes with the split core 1. Therefore, when the nozzle 2 forms a winding portion that does not interfere with the split core 1, the nozzle 2 and the center plane 5
Nozzle 2 is divided into divided cores 1 without changing the angle between
The winding conductor 3 may be wound around the core portion 1b by relatively rotating the winding conductor 3 around the core portion 1b.

According to the method of the present invention, the winding conductor 3 is wound while appropriately changing the angle θ of the nozzle 2 with respect to the center plane 5 of the split core 1 so that the nozzle 2 does not interfere with the split core 1. Therefore, the winding conductor 3 is arranged so that the winding conductor 3 is disposed also in a narrow space portion formed between the side surfaces 1f1 and 1f2 of the iron core portion 1b and the curved inner surface 1d of the yoke portion 1a. 3 can be wound around the iron core 1b. As a result, the space factor can be significantly increased as shown in FIG.

How to change the angle θ between the nozzle 2 and the center plane 5 can be considered in several ways depending on the winding method of the winding conductor. FIG. 3 is a diagram for explaining a mode of change of the angle θ with respect to the center plane 5. In this drawing, θ0 ° = 90 ° −θ °. That is, θ determined by the degree of curvature of the inner surface 1d of the yoke portion 1a of the split core 1
Θ0 ° is changed so that 3 ° (the angle between the plane perpendicular to the center plane 5 and the tangent plane passing through the end of the inner surface 1d) and θ0 ° have the following relationship.

Θ0 ° = 90 ° −θ ° = (θ3 ° / 2) + α where α varies depending on the position where the winding conductor is wound.
The right side of FIG. 3 shows an example of the relationship between the position where the winding conductor is wound and the change in the nozzle inclination angle θ0 ° = 90 ° −θ °. In this example, the side of the iron core 1b and the yoke 1
When the winding conductor 3 is wound at a position where the inner surface 1d of the yoke portion a intersects, θ0 ° is set to 20 ° (θ ° is set to 70 °). The position where the winding conductor 3 is wound is the pole piece 1c.
, The angle θ0 ° is 90 ° (θ ° is 0
(Degree), the angle of the nozzle is changed.

The example of FIG. 3 is merely an example. In order to facilitate setting and changing the angle, the position where the winding conductor 3 is wound is divided into a plurality of regions, and the left and right angles θ 1 and θ 2 are determined in each region. These angles may be changed when the area is changed, while being kept constant. When the winding is wound at a position where the nozzle 2 and the split core 1 do not interfere with each other, when the nozzle 2 is rotated around the split core 1, the angle θ
The winding conductor may be wound at a constant angle (eg, 0 degrees). In such a case, when forming the winding part 4, one or both of the nozzle 2 and the split core support are moved to cause a relative rotational movement between the nozzle 2 and the split core 1. generate. When it is not necessary to change the angle of the nozzle 2 while the nozzle 2 makes one rotation around the outer circumference of the split core 1, the split core support is moved to obtain relative rotation. By doing so, the winding conductor can be wound quickly. When it is necessary to change the angle of the nozzle 2 while the nozzle 2 makes one rotation around the outer circumference of the divided core 1, the relative rotation is obtained by moving both the nozzle 2 and the divided support base. By doing so, the winding conductor can be wound faster.

In the case where the winding conductor is wound by using the method of the present invention, the occurrence of winding collapse (a phenomenon in which the wound winding conductor is displaced) is prevented, and the winding is aligned. The winding method or the winding method of the winding conductor for winding is arbitrary. One example will be described with reference to FIG.
The numbers given to the respective parts in FIG. 4 indicate the winding order of the winding conductor, and the arrows indicate the winding order. In this example, first, a winding conductor is wound around the core portion 1b along the iron core portion 1b with a portion where the side surface 1f2 of the iron core portion 1b intersects with the inner surface 1d of the yoke portion 1a or a position near the intersection portion as a winding start position. Turn 2
Fully wound layers of layers (layers with numbers 1 to 8 and layers with numbers 9 to 18)
To form Next, the winding conductor is wound on the complete winding layer so that the length of the winding layer in the direction along the iron core portion 1b becomes shorter toward the outside, and the yoke portion side winding layer (number 19 to 19) 3
8) is formed. In this example, six short wound layers (numbers 19 to 24, numbers 25 to 29 and 42, numbers 30 to 33)
And 41, numbers 34 to 36 and 40, numbers 37 and 3
9, the layer of No. 38) constitutes the yoke portion side wound layer. It is sufficient that the length of the wound layer in the direction along the iron core portion is shorter as it goes outward, and the order of forming or the forming method is arbitrary. Then, the complete wound layer (the layers of Nos. 1 to 8 and the Nos. 9 to 18)
The winding conductor is wound along the core portion 1b on a portion which is not covered by the yoke portion side winding layer on the side of the yoke portion to form a winding layer (layers with numbers 43 to 46, numbers 47 to 50). Layer, number 51
Layers 56 to 56; layers 57 to 63; layers 64 to 72; layers 73 to 81; layers 82 to 88;
Layers 9-94, layers 95-98, numbers 99 and 10
0 layer) to complete the winding part. The winding procedure or the winding method of the winding conductor at this time is also arbitrary, but it is preferable that the winding is performed so that the winding conductors constituting the winding layer are aligned. When winding the winding conductor in this winding order,
What is necessary is just to change the angle of the nozzle 2 according to the example shown in FIG.

FIG. 5 shows a winding sequence of another winding method in which a yoke portion side winding layer is formed in advance similarly to the example of FIG. Also in this example, first, a winding conductor is wound around the core portion 1b along the core portion 1b with a portion where the side surface 1f2 of the iron core portion 1b intersects with the inner surface 1d of the yoke portion 1a or a position near the intersection. By turning, two completely wound layers (layers of numbers 1 to 8 and layers of numbers 9 to 18) are formed. Next, the winding conductor is wound on the complete winding layer so that the length of the winding layer in the direction along the iron core portion 1b becomes shorter toward the outside, and the yoke portion side winding layer (number 19 to 19) 43) is formed. In this example, FIG.
The winding conductor is wound so as to increase diagonally to the left as viewed in the drawing, unlike the example of FIG.
0, 24, 25, 32, 33, and 43) constitute a yoke-side wound layer. Next, the winding conductor is wound along the core portion 1b on a portion not covered by the yoke portion side winding layer on the complete winding layer side to form a winding layer (layers of numbers 44 to 46). , Layers of numbers 47 to 50, number 51
Layers 56 to 56; layers 57 to 63; layers 64 to 72; layers 73 to 81; layers 82 to 88;
Layers 9-94, layers 95-98, numbers 99 and 10
0 layer) to complete the winding part.

According to the above two winding orders or winding methods, the yoke portion side winding layer is formed first, and the space portion on the yoke portion side is filled with the winding conductor. There is an advantage that occurrence of is difficult. Also, in the winding work of the winding conductor after winding the yoke part side winding layer, if the yoke part side winding layer is formed to the extent that it is not necessary to change and set the nozzle angle, the winding The rotation speed can be increased.

FIG. 6 shows still another winding method. In this example, the winding conductor is wound around the core along the core 1b with the region where the side surface 1f2 of the core 1b intersects with the inner surface 1d of the yoke 1a as the winding start region. The layers (Nos. 1 to 8) are formed, and the winding conductor is wound around the iron core along the core portion 1b on the next first fully wound layer to form the next fully wound layers (Nos. 9 to 18). , And thereafter, this is repeated to form a plurality of completely wound layers (Nos. 19 to 28... Nos. 99 to 100).
To complete the winding part.

FIGS. 7 and 8 are a schematic side view and a schematic front view, respectively, of an example of the winding device 10 for carrying out the method of the present invention. In these figures, reference numeral 11 denotes a base on which a split core supporting device 13 having a split core support 12 for supporting the split core is placed. The base 11 is placed on a worktable of an appropriate height. The split core support device 13 includes a support base moving mechanism 14 that moves the split core support base 12 in the X direction and the Y direction. This support base moving mechanism 14
Is a known X motor that moves using a servo motor M1 driven when moving the split core support 12 in the X direction and a servomotor M2 driven when moving the split core support 12 in the Y direction. -Y table moving mechanism. Due to the operation of the support base moving mechanism 14, the split core support base 12 becomes X-
Move arbitrarily in the Y direction. Although not shown, a plurality of (six in the drawing) split cores 1A1 to 1B3 necessary to constitute one stator are provided on the split core support 12.

A vertical frame 15 extending in the vertical direction is fixed to the base 11. This vertical frame 15
, The winding conductor supply device 16 is fixed to be movable in the Z-axis direction and the X-axis direction. The winding conductor supply device 16 includes:
A nozzle supporter 17 for rotatably supporting the three nozzles 2A to 2C, a nozzle moving mechanism 18 for moving the nozzle supporter 17 in the Z direction and the X direction, and three rotation axes extending in the Y direction Three nozzles 2A to 2C centering on 19
And a nozzle rotating mechanism 20 for rotating the nozzle within a predetermined angle range. Nozzle support 1 of winding conductor supply device 16
Reference numeral 7 denotes a support plate 17a and three nozzle fixing arms 17b rotatably supported by the support plate 17a and fixed to three rotation shafts 19 arranged in the X direction. As a result, the three nozzles 2A to 2C are arranged at predetermined intervals in the X direction. A winding conductor wound on a winding reel (not shown) is supplied to each of the nozzles 2A to 2C via a feed mechanism (not shown).

The nozzle moving mechanism 18 includes a nozzle support 17
The servo motor M3 for moving the nozzle support 17 in the Z direction and the servo motor M4 for moving the nozzle support 17 in the X direction are used as drive sources to move the nozzle support 17 arbitrarily in the XZ direction. . The specific configuration thereof is the same as that of the well-known X-
This is similar to the Y table moving mechanism. Nozzle rotation mechanism 20

Although not shown, the split core support is moved so as to perform relative movement between the split core support base 12 and the nozzles 2A to 2C so that the winding conductor 3 is wound around the iron core 1b. A controller for controlling the device 13 and the winding conductor supply device 16 is provided. The configuration of this controller is arbitrary. For example, when the winding conductor 3 is wound around the side surfaces 1f1 and 1f2 of the iron core 1b, the controller passes through the center of the split core so that the nozzles 2A to 2C do not interfere with the corresponding split cores 1A1 to 1A3. The nozzle rotation mechanism 20 of the winding conductor supply device is controlled so as to determine the angle of the nozzle with respect to. Further, the controller performs an operation necessary for winding the winding conductor 3 around the iron core portion 1b so as to fill a space S formed between the yoke portion and the pole piece portion. Control is performed by the support base moving mechanism 14, the nozzle moving mechanism 18 of the winding conductor supply device 16, and the nozzle rotating mechanism 20. This controller can be configured to include a microcomputer and a motor driving device.

Next, a description will be given of the operation in the case where the process shown in FIG. 2 is performed to form a winding portion on three divided cores for three phases using this apparatus. First, in order to wind the winding conductor around the first three divided cores 1A1 to 1A3 at the same time, the nozzle moving mechanism 18 is controlled by the controller to move the nozzle support 17 to the position shown by the broken line in FIG. In this state, the nozzle rotating mechanism 20 is controlled by the controller to divide the nozzles 2A to 2C (hereinafter, reference numeral 2 is used to maintain consistency with the reference numerals in FIG. 2) to the respective center planes of the divided cores 1A1 to 1A3. At a predetermined angle. As shown in FIGS. 2 (1) and 2 (2), when the winding conductor 3 is wound around the side surface 1f2 of the iron core 1b, the support base moving mechanism 14 controlled by the controller supports the split core support. Table 12 is Y
The nozzle 2 is moved in one of the directions (behind the plane of the paper), and the nozzle 2 is inclined rightward with respect to the center plane 5 by θ1 to perform the winding operation. After the winding conductor 3 is wound around the side surface 1f2 of the iron core 1b, the support moving mechanism 14 moves the split core support 12 in one of the X-axis directions (to the right in FIG. 8). . At this time, the nozzle moving mechanism 18
Moves the nozzle support 17 in the other direction of the X-axis direction (FIG. 8).
(Left side as seen in). By doing so, the moving range of the split core support base 12 in the X direction can be reduced. While this operation is being performed, the nozzle rotating mechanism 20
Is a counterclockwise rotation of the rotation shaft at a predetermined angle,
The angle of the nozzle 2 with respect to the center plane 5 is changed. Thus, as shown in FIG. 2 (3), the end face 1g2 of the iron core 1b is formed.
The nozzle 2 is moved to a position at some distance from
As shown in (3) to FIG. 2 (5), during the operation of winding the winding conductor 3 around the end face 1g2 of the iron core 1b, the nozzle 2
Rotates by θ1 + θ2 degrees.

Next, the angle between the nozzle 2 and the center plane 5 is θ
2 While maintaining the state, as shown in FIGS. 2 (5) to 2 (7), the winding conductor 3 is wound around the side surface 1f2 of the iron core 1b. At this time, the support base moving mechanism 14 moves the split core support base 12 in the other direction of the Y-axis direction (forward direction as viewed in the plane of FIG. 8). Nozzle 2 is end face 1g of iron core 1b
When the pressure exceeds 1, the nozzle 2 is moved to a position which is away from the end face 1g1 of the iron core 1b to a certain extent as shown in FIG. 2 (8), and then the direction is opposite to that of FIGS. 2 (3) to 2 (5). During the operation of winding the winding conductor 3 around the end face 1g1 of the iron core 1b, the nozzle 2 is rotated by θ1 + θ2 degrees to return to the state of FIG. In this operation, the support base moving mechanism 14 moves the split core support base 12 in the other direction of the X-axis direction (to the left as viewed in FIG. 8). And the nozzle moving mechanism 18
Shows that the nozzle support portion 17 is moved in one of the X-axis directions (FIG. 8).
(To the right as seen in). While this operation is being performed, the nozzle rotation mechanism 20 changes the angle of the nozzle 2 with respect to the center plane 5 of the nozzle 2 by rotating the rotation axis clockwise by a predetermined angle, as shown in FIG. Return to the state. Thereafter, this operation is repeated while the nozzle moving mechanism 18 moves the nozzle supporter 17 little by little in the Z-axis direction and the X-axis direction.

When the winding conductor can be wound without changing the angle of the nozzle 2, the nozzle rotating mechanism 20 rotates the rotating shaft 19 so that the nozzle 2 is substantially vertical. Then, the support moving mechanism 14 causes the split core support 12 to perform a box operation (a movement in which the locus becomes rectangular) in the X-Y directions to wind the winding conductor around the iron core 1b. At this time, the nozzle moving mechanism 18 moves the nozzle support 17 to Z
Move gradually in the axial direction.

The above operation is an operation in the case where the process of FIG. 2 is performed, and it goes without saying that other operations may be performed to form an arbitrary winding portion.

According to the present invention, the winding conductor is wound while appropriately changing the angle of the nozzle with respect to the center plane of the split core so that the nozzle does not interfere with the split core. The winding conductor can also be wound around the iron core so that the winding conductor exists also in the space formed between the wire core and the curved inner surface of the yoke. As a result, the space factor can be greatly increased as compared with the related art. In addition, the winding conductor can be wound in a state where the winding conductor is present in the space formed between the side surface of the iron core portion and the curved inner surface of the yoke portion. The occurrence of winding collapse during the turning operation can be prevented. Therefore, it is possible to arrange and wind the winding conductor.
