Description

  The present invention mainly relates to a flyer-type winding machine and a winding method for winding a wire for forming a coil around a multipole armature.

  Conventionally, in order to wind a wire for forming a coil around a magnetic pole of a multipole armature, a flyer-type winding provided with a flyer that feeds the wire while rotating around the magnetic pole and winds the wire around the magnetic pole. Wire machines are widely used. In order to improve the performance with the limited size of the armature, such as a motor, how many windings can be made in the limited winding space of the multi-pole armature Required for wire machines. For this purpose, so-called aligned winding is effective, in which winding is performed without gaps between the wires adjacent to the magnetic pole. For this reason, a flyer type winding machine is known which includes a pair of center formers arranged so as to sandwich the magnetic poles from the axial direction of the multipole armature (see, for example, Patent Document 1). ).

  That is, in this flyer-type winding machine, the center former sandwiches the magnetic pole to be wound by the multi-pole armature from the axial direction of the multi-pole armature, so that the wire fed from the flyer becomes the guide surface of the center former. Slide and guide from its tip to the desired position of the pole to be wound. And it is supposed that aligned winding is performed by moving the flyer which feeds a wire rod while rotating in the direction of the rotation axis together with the center former.

  After the flyer that feeds the wire moves in the direction of the rotation axis and the first layer winding is formed on the magnetic pole, the flyer that feeds the wire while rotating is opposite to the direction in which the first layer is wound. The second winding is applied on the first winding wound around the magnetic pole. It is known that a plurality of layers of windings are applied to the magnetic poles by repeating this sequentially and reciprocating the rotating flyer in the direction of the rotation axis.

  However, when the rotating flyer is reciprocated in the direction of the axis of rotation and a plurality of layers of winding are applied to the magnetic pole, the winding direction of each layer is alternately reversed, so in the layer wound above Each time the wire is wound once around the magnetic pole, it intersects the wire in the lower layer winding once.

  Therefore, when the cross section of the magnetic pole on which the wire is wound has a square shape, the lower layer winding and the upper layer winding are parallel on three of the four surrounding surfaces around which the magnetic pole is wound. However, on one of them, the lower layer winding and the upper layer winding intersect each other without being parallel.

  And if the lower layer is aligned and the wire in the upper layer is parallel to the wire in the lower layer, the wire in the upper layer falls into the gap generated between the wires in the lower layer, The winding thickness is less than twice the wire diameter, and the winding thickness does not increase.

  However, if the lower layer is wound in an aligned manner, but the wire in the upper layer intersects the wire in the lower layer, the wire in the upper layer will overcome the wire in the lower layer. The winding thickness is always twice the wire diameter, and the winding thickness is never reduced.

  Conventionally, in a multi-pole armature that performs winding using a flyer-type winding machine, a plurality of magnetic poles are formed radially in the circumferential direction. When it swells in the circumferential direction, a restriction is imposed on the winding to the magnetic pole adjacent in the circumferential direction. For this reason, when winding a plurality of layers on one magnetic pole, the cross section of the magnetic pole is rectangular, so that the wire in the upper layer intersects the wire in the lower layer in the axial direction of the multipole armature. It is preferable to avoid the occurrence of the bulge of the winding in the circumferential direction due to the intersection.

  However, the multipole armature is composed of a relatively large number of laminated plates, and the cross section of the magnetic pole generally has a rectangular shape having a long side in the thickness direction. In order for the upper layer wire to get over the lower layer wire, it is preferable that the crossing angle between the intersecting wires is small. For this reason, when a plurality of layers of winding are applied to the magnetic pole of the multipole armature, the lower layer wire and the upper layer wire easily cross each other with the long cross section of the magnetic pole. Therefore, in a conventional flyer type winding machine, when a multi-layer armature is provided with multiple layers of windings, the windings cross on the long side of the cross-section of the magnetic poles, and the windings are multipole armatures. Tended to swell in the circumferential direction.

  An object of the present invention is to wind a wire in an upper layer intersecting a wire in a lower layer on the surface in the axial direction of the multipole armature when a multi-layer armature is provided with a plurality of layers of windings. An object of the present invention is to provide a flyer type winding machine that can be wired.

  The present invention relates to a flyer for winding a wire rod around a magnetic pole while rotating around the magnetic pole in a multipole armature, and a flyer disposed so as to sandwich the magnetic pole from the axial direction of the multipole armature. Flyer type winding machine provided with a pair of center formers for guiding the wire fed from the magnetic poles to the magnetic poles, and a center former moving mechanism for adjusting the axial position and the radial position of the pair of center formers with respect to the multipole armature It is an improvement.

  The characteristic configuration is that one of the pair of center formers is composed of a pair of former plates that overlap in the circumferential direction of the multi-pole armature, and the center former moving mechanism is one of the pair of former plates. The other former plate is configured to be able to shift in the radial direction of the multipole armature.

  In this case, an opposing former provided to face one center former, an opposing former moving mechanism that moves the opposing former in the radial direction of the multipole armature together with the one center former as the flyer rotates, It is preferable to further include a rotation mechanism that rotates the opposing former in response to the displacement of the pair of former plates.

  A center former moving mechanism is connected separately to the pair of former plates and is movable in the direction of the rotation axis of the flyer, and is connected to the other center former in the direction of the rotation axis of the flyer. It is preferable to include a movable third operating rod and movable means capable of independently moving the first to third operating rods separately in the axial direction.

  Another aspect of the present invention is a flyer that rotates around a magnetic pole in a multipole armature and reciprocates in the radial direction of the multipole armature to wind a wire around the magnetic pole. A pair of center formers disposed so as to be sandwiched from the axial direction of the child and for reciprocating in the radial direction of the multipole armature as the flyer reciprocates and guiding the wire fed from the flyer from the tip edge to the magnetic pole; This is an improvement of a winding method in which a wire rod is wound around each magnetic pole of a multipole armature using a winding device provided with.

  The characteristic point is that one of the pair of center formers is composed of a pair of former plates that overlap in the circumferential direction of the multi-pole armature, and the pair of center formers travels in the radial direction of the multi-pole armature. When one of the pair of former plates is displaced radially inward or outward of the multipole armature with respect to the other, the pair of former plates is moved backward in the radial direction of the multipole armature of the pair of center formers. Any one of these is shifted to the radially outer side or the inner side of the multipole armature with respect to the other.

  In this case, the counter former facing one center former is reciprocated in the radial direction of the multipole armature together with the pair of center formers in accordance with the rotation of the flyer, and the radial former of the multipole armature of the pair of center formers is moved. In the forward movement, one of the pair of former plates is tilted with the pair of center formers by inclining the opposing former along the slope of the pair of former plates shifted inward or outward in the radial direction of the multipole armature. When the armature moves forward in the radial direction and the pair of center formers return in the radial direction of the multipole armature, one of the pair of former plates is displaced outward or inward in the radial direction of the multipole armature. The opposing former is inclined along the inclination of the pair of former plates and moved back together with the pair of center formers in the radial direction of the multi-pole armature. It is preferable to winding guided to the pole from between the Ma and opposing former.

  In the flyer type winding machine and winding method of the present invention, one of the pair of center formers is constituted by a pair of former plates, and one of the former plates is a multipolar armature with respect to the other former plate. I shifted it in the radial direction. By shifting in this way, the wire sliding down the inclined surface of each former plate is guided in a state inclined to the axis of the magnetic pole, and if the wire guided in the inclined state is a wire in the upper layer, the wire Can be crossed with the wire in the lower layer.

  Here, since one of the center formers is provided in the axial direction of the multipolar armature, in the axial direction of the multipolar armature, the wire in the upper layer intersects with the wire in the lower layer, and the multipolar armature It is possible to avoid that the wire in the upper layer intersects the wire in the lower layer in the circumferential direction.

  In addition, when the opposing former is opposed to one center former corresponding to the displacement of the pair of former plates, the wire that slides down the respective inclined surfaces of the former plate in one center former is sandwiched between the former plate and the opposing former. In this state, it is guided to the magnetic pole and guided onto the lower layer winding while maintaining its inclined state, so that the wire in the upper layer can be connected to the lower layer on the surface facing this one center former. It is possible to reliably cross the wire.

Similarly, the operating rods 45a and 45b provided on 44a and 44b are also retracted, and the mounting bases 42a and 42b into which the operating rods 45a and 45b enter the concave grooves 42d and 42e are also connected to the second and third forward / backward guide rails 41a and 41a. It will retreat along 41b. Therefore, the operation tables 44a and 44b move the upper center former 15 together with the mounting tables 42a and 42b in the X-axis direction.

  The upper center former 15 is composed of a pair of former plates 15a and 15b that overlap in the circumferential direction of the multipole armature 1, and operation rods 46a and 46c for moving them forward or backward are also provided separately. Therefore, the center former moving mechanism 17 having the operation rods 46a and 46c moves the operation rods 46a and 46c separately to thereby form one of the former plates 15a and 15b. Can be displaced in the radial direction of the multipole armature 1 with respect to the other former plate 15ab. 3 shows a state in which one former plate 15a is shifted so as to slightly advance toward the multi-pole armature 1 with respect to the other former plate 15b. In FIG. 4, one former plate 15a is moved to the other one. The state which shifted | deviated slightly from the multipolar armature 1 with respect to the former board 15b is shown.

The rollers 40a and 40b fitted into the cam plate 35a and the inclined long holes 35c and 35d move in the movement direction for converting the movement of the operation rod 46d in the X-axis direction into the movement of the pair of center formers 15 and 16 in the Z-axis direction. The conversion means is configured.

  That is, the support rods 39a and 39b with the rollers 40a and 40b pivotally supported at the tips are inserted into the vertical long holes 34c and 34d formed in the side plate 34a, and the vertical movement plates 38a and 38b to which the base ends are attached are It engages with a vertical guide rail 37a (FIGS. 5 and 6) extending in the Z-axis direction. For this reason, the support bars 39a and 39b do not move in the X-axis direction with respect to the side plate 34b. Therefore, as shown in FIG. 7, when the advanced operating rod 46d moves backward together with the cam plate 35a as indicated by the solid line arrow in FIG. 8, the rollers 40a and 40b are inclined by the inclined long holes 35c and 35d by the retreating cam plate 35a.

  On the other hand, as shown in FIG. 8, when the retracted operation rod 46d moves forward together with the cam plate 35a as indicated by the broken arrow in FIG. 7, the rollers 40a and 40b are inclined by the inclined long holes 35c and 35d by the advanced cam plate 35a. In the inside, the rolling movement is made along the inclination of the inclined long holes 35c, 35d. Then, the support rods 39a and 39b are separated from each other in the vertical direction along the vertical elongated holes 34c and 34d. As shown in FIG. 5, since the base ends of the support bars 39a and 39b are attached to the vertical movement plates 38a and 38b, the support bars 39a and 39b that are separated from each other are attached to the support bars 39a and 39b. Together with the vertical moving plates 38a and 38b, they are separated from each other in the vertical direction, which is the direction in which the vertical elongated holes 34c and 34d are formed.

  The winding method of the present invention includes a flyer 4 that rotates around the magnetic pole 2 in the multipole armature 1 and reciprocates in the radial direction of the multipole armature 1 to wind the wire 3 around the magnetic pole 2. The wire 3 that is arranged so as to sandwich the magnetic pole 2 from the axial direction of the multipole armature 1 and reciprocated in the radial direction of the multipole armature 1 along with the reciprocating movement of the flyer 4 is fed from the flyer 4. In this winding method, a wire rod 3 is wound around each magnetic pole 2 of the multipole armature 1 using a winding device 100 having a pair of center formers 15 and 16 guided from the leading edge to the magnetic pole 2.

Specifically, the magnetic pole 2 to be wound is aligned with the direction of the rotation axis C of the flyer 4. Thus, the position facing the rotation axis C of the flyer 4 is the winding position. Although not shown, the alignment of the multipole armature 1 to the winding position is performed by detecting the position of the magnetic pole 2 using a detector (not shown) such as a sensor provided in the vicinity of the magnetic pole 2 and detecting the detected information. On the basis of

Wound along.

  In the process in which the flyer 4 rotates 180 ° from the vertically lower side to the vertically upper side of the magnetic pole 2, the wire 3 fed from the flyer 4 comes into contact with the side former 97 (FIG. 1) and is guided along the slope. At the same time, as shown in FIG. 9 (c), it abuts against the lower center former 16, slides down its inclined surface, and guides from the tip end portion 16 a to the bottom surface of the magnetic pole 2 in the axial direction of the multipole armature 1. And wound around the bottom surface along the annular portion 1a. Although not shown, the wire 3 guided along the slope of the side former 97 is wound around the side surface of the magnetic pole 2 in the circumferential direction of the multipole armature 1 along the annular portion 1a. Thus, as the flyer 4 makes one rotation, the wire 3 is wound once around the magnetic pole 2 along the annular portion 1a.

  Each time the wire 3 is wound around the magnetic pole 2, the traverse mechanism 18 shown in FIG. 1 drives the traverse motor 50 to move the moving table 21 together with the flyer 4 in the winding direction (in the radial direction of the magnetic pole 2). Then, the flyer 4 is moved away from the multipolar armature 1 by the wire diameter of the wire 3 in the rotation axis C direction (X-axis direction).

  When the moving base 21 is moved by the wire diameter of the wire 3 in this way, since the center former moving mechanism 17 is also provided in the moving base 21, in order to make the second turn adjacent to the first turn, In the process in which the flyer 4 again rotates 180 ° from the vertically upper side to the vertically lower side of the magnetic pole 2, the upper center former 15 also moves in the winding direction (the radial direction of the magnetic pole 2 and the rotational axis C direction of the flyer 4 (X-axis direction). )) Is moved by the wire diameter of the wire 3.

  Then, when the upper center former 15 retreats by the wire diameter of the wire 3, the flyer 4 is fed out in the process of rotating 180 ° from the vertically upper side to the vertically lower side of the magnetic pole 2 as shown in FIG. The wire 3 abuts on the upper center former 15, and the upper center former 15 guides the wire 3 sliding down the inclined surface to a position adjacent to the first winding of the magnetic pole 2 from its tip portions 15 c and 15 d. Align winding.

  At this time, the pair of former plates 15a and 15b in the upper center former 15 shifts one of the pair of former plates 15a and 15b toward the inside or outside in the radial direction of the multipolar armature 1 with respect to the other. Specifically, the former plate 15 b on the downstream side in the rotational direction of the flyer 4 is shifted in the moving direction of the flyer 4 with respect to the former plate 15 a on the upstream side in the rotational direction of the flyer 4. In FIG. 10 (a), the multi-pole armature is in the first layer winding, and the former plate 15b on the downstream side in the rotational direction of the flyer 4 is replaced with the former plate 15a on the upstream side in the rotational direction of the flyer 4. 1 shows a case of shifting outward in the radial direction.

  As shown in FIG. 2, the pair of former plates 15a and 15b is displaced in the X-axis direction together with the operation tables 44a and 44b by moving either one or both of the operation rods 46a and 46c constituting the center former moving mechanism 17. This is performed by moving the pair of former plates 15a and 15b attached to them.

  When shifted in this way, the former plate 15a on the upstream side in the rotational direction of the flyer 4 prohibits the first wire rod 3 from shifting outward in the radial direction of the multipole armature 1, while the downstream side in the rotational direction of the flyer 4 The former plate 15b guides the wire 3 sliding down the inclined surface to a position adjacent to the first winding of the magnetic pole 2 from the tip portions 15c and 15d (FIG. 10B).

  Thereafter, in the second half of the second winding, the flyer 4 rotates again by 180 ° from the vertically lower side to the upper side of the magnetic pole 2. In the process, as shown in FIG. 10 (c), the lower center former 16 also moves the wire 3 in the winding direction (the radial direction of the magnetic pole 2 and the rotation axis C direction (X-axis direction) of the flyer 4). Move by the wire diameter. In this way, the lower center former 16 is retracted by the wire diameter of the wire 3, and the wire 3 fed out in the process in which the flyer 4 rotates 180 ° from the vertically lower side to the upper side of the magnetic pole 2 is The wire rod 3 sliding down the inclined surface is brought into contact with the center former 16 and guided to the position adjacent to the first winding of the magnetic pole 2 from the tip end portion 16a, and aligned winding is performed.

  As the flyer 4 rotates, the opposing former 80 facing the one center former 15 is moved in the radial direction of the multipole armature 1 together with the pair of center formers 15 and 16. Then, during the forward movement of the pair of center formers 15 and 16 in the radial direction of the multi-pole armature 1, the opposing former 80 is inclined according to the displacement of the pair of former plates 15a and 15b, and FIG. As shown in FIG. 3, the flat plate portion 80a is opposed to the flat plate portion 80a along the shift so that the wire rod 3 is sandwiched with a slight gap together with the tip portions 15c and 15d of the pair of former plates 15a and 15b which are shifted. In this state, the opposing former 80 is moved forward in the radial direction of the multipole armature 1 together with the pair of center formers 15 and 16.

  Here, the rotation of the opposing former 80 is performed by the rotation mechanism 82 shown in FIG. 1, and the opposing former is rotated so that the flat plate portion 80a is opposed to the tip portions 15c and 15d which are displaced from the pair of former plates 15a and 15b. The movement 80 is performed by the opposed former moving mechanism 83 shown in FIG.

  These windings are repeated, and the pair of center formers 15 and 16 and the opposing former 80 are sequentially moved away from the multipolar armature 1 by the wire diameter of the wire 3 along with the movement of the flyer 4 in the rotational axis direction. Wind while doing.

  In this way, by moving the pair of center formers 15 and 16 and the opposing former 80 that guide the wire 3 to the magnetic pole 2 together with the flyer 4, the wire rod 3 is fed by one wire diameter for one rotation of the flyer 4. As shown in FIG. 11, the magnetic pole 2 is formed with a so-called aligned winding in which the wire 3 is in close contact with the radial direction of the multipole armature 1, and the magnetic pole 2 has a first layer winding. A line will be formed.

  In this first layer winding, the pair of center formers 15 and 16 move in the X-axis direction, which is the rotation axis C direction of the flyer 4, before the first layer winding shown in FIG. 11 is completed. The tip portions 15c, 15d, and 16a may come into contact with the flange portion 2a. In this case, in order to continue the subsequent aligned winding of the first layer, the center formers 15 and 16 immediately before the tip portions 15c, 15d and 16a of the pair of center formers 15 and 16 come into contact with the flange portion 2a. Is moved in the axial direction of the multipole armature 1 to avoid contact thereof.

  The center formers 15 and 16 are moved in the axial direction of the multipole armature 1 by advancing the operation rod 46d constituting the center former moving mechanism 17 in the axial direction. Then, the cam plate 35a connected to the operation rod 46d also moves forward, the support rods 39a, 39b are separated from each other in the vertical direction along the vertical elongated holes 34c, 34d, and the support rods 39a, 39b separated from each other are supported by the support plates 39a, 39b. Along with the vertical movement plates 38a and 38b to which the rods 39a and 39b are attached, they are separated from each other in the vertical direction, which is the direction in which the vertical elongated holes 34c and 34d are formed. It will be separated. Thereby, the aligned winding of the first layer can be continued. Then, the winding of the first layer is terminated when the wire 3 comes into contact with the flange 2 a of the magnetic pole 2.

  In the first layer winding, the opposing former 80 also moves in the X-axis direction, which is the rotational axis C direction of the flyer 4, together with the pair of center formers 15 and 16, before the first layer winding is completed. Further, the flat plate portion 80a may come into contact with the flange portion 2a. In this case, the counter former 80 is moved in the axial direction of the multipole armature 1 immediately before the flat plate portion 80a of the counter former 80 abuts against the flange portion 2a in order to continue the subsequent winding of the first layer. Thus, the contact is avoided. The movement of the opposed former 80 in the axial direction of the multipole armature 1 can be performed by the Z-axis direction extendable actuator 86 in the opposed former moving mechanism 83.

  Then, after the first layer winding is completed as shown in FIG. 11, the second layer winding is performed. The second-layer winding rotates the flyer 4 in the same direction as in the first layer and winds the wire 3 around the magnetic pole 2, while the traverse motor 50 is connected to the first-layer winding. Is rotated in the opposite direction, and the flyer 4 is moved in the direction approaching the multipole armature 1. Then, along with the movement of the flyer 4, the center formers 15 and 16 are similarly moved in the direction approaching the multipolar armature 1 as shown in FIG.

  At the start of the second layer winding, the pair of center formers 15 and 16 move from the state shown in FIG. 11 in a direction approaching the multipolar armature 1 as indicated by solid arrows in FIG. . Then, when the tip portions 15c, 15d, and 16a move to positions shifted from the flange portion 2a, the pair of center formers 15 and 16 reduce the distance between each other, and the first layer wound around the magnetic pole 2 The leading ends 15c, 15d, and 16a are sandwiched between the windings with a slight gap from the Z-axis direction. As a result, the wire 3 can be guided to the magnetic pole 2 to enable stable aligned winding in the second layer.

  Thus, in the second layer winding, the rotating flyer 4 is moved in the opposite direction to the first layer winding, so that the wire 3 in the second layer is placed on the magnetic pole 2. Each time it is wound once, it intersects the wire 3 in the winding of the first layer which is the lower layer once. When the wire 3 in the upper layer intersects with the wire 3 in the lower layer in this way, the wire 3 in the upper layer gets over the wire 3 in the lower layer.

  Here, in the multipole armature 1, a plurality of magnetic poles 2 are radially formed in the circumferential direction. Therefore, when the windings in one magnetic pole 2 swell in the circumferential direction of the multipolar armature 1, they are adjacent to each other in the circumferential direction. There is a restriction on the winding to the magnetic pole 2. For this reason, when a multi-layer winding is performed on one magnetic pole 2, the cross section of the magnetic pole 2 is square, so that the wire 3 in the upper layer is connected to the lower layer in the axial direction of the multipole armature 1. It is preferable to cross the wire 3.

  For this reason, in the winding method of the present invention, in the second layer winding, the pair of former plates 15a and 15b is shifted in the opposite direction to that in the first layer winding. Specifically, as shown in FIG. 12A, the diameter of the multi-pole armature 1 is set so that the former plate 15 b on the downstream side in the rotational direction of the flyer 4 is different from the former plate 15 a on the upstream side in the rotational direction of the flyer 4. Shift inward.

  The displacement of the pair of former plates 15a and 15b is caused by moving either one or both of the operation rods 46a and 46c constituting the center former moving mechanism 17 so as to be displaced in the X-axis direction together with the operation tables 44a and 44b. This is done by shifting the pair of attached former plates 15a and 15b.

  When shifted in this way, the wire rod 3 that slides down the inclined surfaces of the former plates 15a and 15b is guided and tilted from the tip portions 15c and 15d onto the winding of the first layer of the magnetic pole 2. The wire 3 in the second layer guided in the state intersects with the wire 3 in the first layer which is the lower layer. Therefore, in the present invention, in the axial direction of the multipole armature 1, the wire 3 in the upper layer can intersect with the wire 3 in the lower layer.

  In addition, in the counter former 80 facing the one center former 15 as the flyer 4 for winding in the second layer turns, the multi-polarity together with the pair of center formers 15 and 16 is provided. The armature 1 is moved in the radial direction. When the pair of center formers 15 and 16 are moved back in the radial direction of the multi-pole armature 1, the opposing former 80 is inclined by the displacement of the pair of former plates 15a and 15b, and the flat plate portion 80a is made to be a pair of formers. The plates 15a and 15b are opposed to each other with a gap slightly wider than the wire diameter of the wire 3 along the inclination of the plates 15a and 15b.

  The opposing former 80 in this state is moved backward together with the pair of center formers 15, 16 in the radial direction of the multipole armature 1, and the wire 3 fed from the flyer 4 is magnetically poled between the center former 15 and the opposing former 80. Guide to 2 and wind. The counter former 80 is rotated by the rotating mechanism 82 shown in FIG. 1, and the counter former 80 is moved by the counter former moving mechanism 83 shown in FIG.

  Then, as shown in FIG. 12 (b), the wire rod 3 sliding down the inclined surfaces of the former plates 15a and 15b in the upper center former 15 is sandwiched between the former plates 15a and 15b and the opposing former 80. Since it is guided by the magnetic pole 2 and guided on the winding of the first layer while maintaining its inclined state, the wire 3 is not dragged by the recesses between the wires 3 of the lower layer, and the wire 3 in the second layer. Can be reliably crossed with the wire 3 in the first layer, which is the lower layer, on the surface facing the upper center former 15.

  In the second layer winding, as shown in FIG. 12C, the lower center former 16 is also in the winding direction (the radial direction of the magnetic pole 2) every time the flyer 4 rotates once. The flyer 4 moves in the rotation axis C direction (X-axis direction) by the wire diameter of the wire 3. Then, even in the lower center former 16, the wire 3 drawn out in a process in which the flyer 4 is rotated 180 ° from the vertically lower side to the upper side of the magnetic pole 2 is brought into contact with the lower center former 16. Then, the wire 3 that slides down the inclined surface is guided to the position adjacent to the wire 3 previously wound on the winding of the first layer from the tip portion 16a, and the aligned winding of the second layer is performed. Then, as shown in FIG. 13, the winding of the second layer is terminated when the wire 3 is wound until it comes into contact with the annular portion 1a.

  Subsequently, although the third layer winding is performed, this third layer winding is the same as the first layer winding procedure, and when performing the fourth layer winding, Since it is the same as the winding procedure of the second layer, repeated description is omitted.

  When all the windings scheduled for the magnetic pole 2 are completed, the multi-pole armature 1 is rotated by driving the index motor 9, and the one magnetic pole 2 and the other magnetic pole 2 are moved to the winding position. The winding work for the multi-pole armature 1 can be completed when the winding is completed and winding is completed for all the magnetic poles 2.

  Here, in the present invention, when a plurality of layers of windings are applied to the magnetic pole 2 of the multipole armature 1, the wire 3 in the upper layer is replaced with the wire in the lower layer on the surface in the axial direction of the multipole armature 1. 3 can be crossed and wound. For this reason, on the surface of each magnetic pole 2 in the circumferential direction of the multipolar armature 1, the wire 3 in each layer is arranged in parallel with no gap between them, so the wire 3 in the upper layer is also the wire 3 in the lower layer. The wire 3 in the upper layer falls into a gap formed between the wires 3 in the lower layer.

  For this reason, the winding thickness of the surface of each magnetic pole 2 in the circumferential direction of the multipolar armature 1 is less than twice the wire diameter, and the winding thickness does not increase. Therefore, in the plurality of magnetic poles 2 formed radially in the circumferential direction of the multipole armature 1, the winding in one magnetic pole 2 does not restrict the winding to the magnetic pole 2 adjacent in the circumferential direction. Thus, the number of wires 3 that can be wound around each magnetic pole 2 can be increased.

  In the above-described embodiment, the case where the upper center former 15 is configured by the pair of former plates 15a and 15b has been described. However, although not shown, the lower center former 16 may be constituted by a pair of former plates. Thus, even if the lower center former 16 is constituted by a pair of former plates, any one of the pair of former plates at the time when the pair of center formers 15 and 16 are moved forward in the radial direction of the multipolar armature 1. One of the pair of former plates is displaced when one of the pair of center formers 15 and 16 is moved backward in the radial direction of the multipolar armature 1 by shifting one of them to the radially inner side or the outer side of the multipolar armature 1 Is shifted outward or inward in the radial direction of the multipole armature 1 with respect to the other, so that the wire 3 in the upper layer intersects the wire 3 in the lower layer on the surface in the axial direction of the multipole armature 1. Can be wound.
