Description

TECHNICAL AREA

The present invention mainly relates to a flyer winding machine and a winding method for winding a wire for forming a coil on a multi-pole armature.

STATE OF THE ART

Conventionally, the winding of a wire for forming a coil onto a magnetic pole of a multi-pole armature is realized by the widespread use of a flyer winding machine including a flyer which feeds the wire while rotating around the magnetic pole. In order to improve the performance of an engine or the like within the size limitations of the armature, there is a need for a flyer winding machine for winding the wire in a large volume on the magnetic pole within the limited winding space of the multi-pole armature. For this purpose, so-called oriented winding, ie, winding of the wire on the magnetic pole in an aligned manner without a gap between adjacent turns of the wire, is effective. JP 2002-34211A discloses a flyer winding machine that can perform an oriented winding using a pair of center formers contained therein. The pair of center formers is arranged so that it can include a magnetic pole in an axial direction of a multi-pole armature.

In this flyer winding machine, the center formers include the magnetic pole of the multipolar armature in the axial direction of the multipolar armature. A wire supplied by a flyer slides on guide surfaces of the center formers and is guided from the ends of the center formers to a desired position on the magnetic pole. Oriented winding is performed as the flyer feeding the wire rotates along the axis of rotation moving with the center formers.

After the flyer has formed the first winding layer on the magnetic pole by moving along the axis of rotation while feeding the wire, the flyer forms the second winding layer over the first winding layer by moving in a direction corresponding to the direction of travel of the flyer of forming the first winding layer is opposite. These operations are repeatedly performed sequentially while the rotating flyer reciprocates along the rotation axis. As a result, a plurality of winding layers are formed at the magnetic pole.

SUMMARY OF THE INVENTION

When multiple winding layers are formed at the magnetic pole by the reciprocating motion of the rotating flyer along the axis of rotation of the flyer, the winding direction alternates from one layer to the next. Each time the wire is wound onto the magnetic pole with one turn, it once crosses the wire in an underlying winding layer.

Thus, when the magnetic pole has a quadrangular cross-section and when the wire in a lower layer is parallel to the wire in an upper layer on three faces of the four faces of the circumference of the magnetic pole, the wire in the lower layer and the wire in the upper layer cross on the remaining surface each other and are not parallel to each other.

When the lower layer is in the form of an oriented winding and the wire in the upper layer is parallel to the wire in the lower layer, the wire in the upper layer sinks into the lower-wire indentations of the lower layer. In this case, the winding thickness is not large because it is smaller than twice the wire diameter.

In contrast, when the lower layer is in the form of an oriented winding and when the wire in the upper layer crosses the wire in the lower layer, the upper layer rides over the wire in the lower layer. In this case, the winding thickness is not small because it is twice the wire diameter.

A flyer winding machine performs winding on a multi-pole armature having a plurality of magnetic poles arranged radially in a circumferential direction of the multi-pole armature. When the wire wound on a magnetic pole becomes bulky in the circumferential direction of the multi-pole armature, restrictions are imposed on the winding at magnetic poles adjacent to the circumference. When a plurality of winding layers are formed on the magnetic pole having a quadrangular cross section, the wire in an upper layer and the wire in a lower layer preferably cross each other, viewed from the axial direction of a multi-pole armature, around a voluminousity of the wound wire in the circumferential direction caused by crossing to prevent.

The multi-pole anchor consists of a relatively large number of laminated plates. Generally, the cross sections of the magnetic poles have a rectangular shape whose long sides are in a thickness direction of the laminated plates extend. The wire in an upper layer simply rides over the wire in a lower layer as they cross each other at a small angle. Thus, when a plurality of winding layers are formed at a magnetic pole of the multi-pole armature, the wire in a lower layer and the wire in an upper layer simply cross each other on the surfaces of the magnetic pole corresponding to the long sides of the cross section of the magnetic pole. Thus, when a plurality of winding layers are formed on a magnetic pole of a multi-pole armature using a conventional flyer winding machine, the wound wire tends to cross on the long sides of the cross section of the magnetic pole and becomes bulky in a circumferential direction of the multi-pole armature.

It is an object of the present invention to provide a flyer winding machine that can wind a wire onto a magnetic pole such that the wire in an upper layer crosses the wire in a lower layer on one or more surfaces of the magnetic pole that is an axial direction of a multi-pole armature cross.

According to one aspect of the present invention, a flyer winding machine includes: a flyer configured to wind a wire on a magnetic pole of a multi-pole armature by supplying the wire while rotating around the magnetic pole; a pair of center formers arranged to enclose the magnetic pole in an axial direction of the multipolar armature, the pair of center formers being configured to guide the wire fed from the flyer from vertex sides to the magnetic pole; and a center shaper moving mechanism configured to adjust positions of the pair of center shifters in the axial direction and in a radial direction of the multi-pole armature relative to the multi-pole armature, one of the pair of center shifters having a pair of shaper plates arranged one inside the other Overlapping the circumferential direction of the multi-pole armature, and wherein the central shaper moving mechanism is configured to move one of the pair of shaper plates in the radial direction of the multi-pole armature relative to the other of the pair of shaper plates.

Because the pusher 49 on the pair of side plates 34a . 34b is mounted, bringing forward the pair of side plates 34a . 34b the pusher 49 in contact with an outer end surface of the magnetic pole 2 , The pusher 49 prevents the magnetic pole 2 relative to the axis of rotation C of the flyer 4 is moved while in contact with the outer end surface of the magnetic pole 2 under the urging force of the spring, not shown.

Thereafter, the center shaper movement mechanism places 17 the end parts 15c . 15d . 16a at a near end part of the magnetic pole 2 as in 9B shown by taking the positions of the pair of center shapers 15 . 16 in the axial direction and the radial direction of the multi-pole armature 1 relative to the multipole anchor 1 established. In particular, the positions of the pair of center shapers become 15 . 16 in the radial direction of the multi-pole armature 1 relative to the multipole anchor 1 set such that there is a gap in which the wire 3 can be inserted between the end parts 15c . 15d . 16a and the annular part 1a of the multipolar anchor 1 is formed.

The positions of the pair of center shapers 15 . 16 in the axial direction of the multi-pole armature 1 relative to the multipole anchor 1 are adjusted so that the end parts 15c . 15d . 16a of the pair of center shapers 15 . 16 the magnetic pole 2 in the Z-axis direction (a thickness direction).

Then it will be in a state where the flyer 4 is positioned higher than the magnetic pole 2 in the vertical direction as in 1 shown, the flyer rotary engine 29 operated to the flyer 4 together with the main spindle shaft 24 to turn. The one on the pen 1d locked wire 3 becomes the circumference of the magnetic pole 2 as in 9A shown led. After that, the flyer 4 fed wire 3 around the magnetic pole 2 wound.

As in 2 shown, the rotation of the main spindle shaft 24 to the first to fourth spindle shafts 61b . 66b . 71b . 76b about the leadership wave 58 transfer. That is, the first to fourth spindle shafts 61b . 66b . 71b . 76b synchronous with the rotation of the flyer 4 rotate. Accordingly, the wire supplied from the wire feeding source can be 3 to the nozzle 27 be guided without being twisted.

In the process of 180-degree rotation of the flyer 4 from the position vertically higher than the magnetic pole 2 to the position vertically lower than the magnetic pole 2 comes through the flyer 4 fed wire 3 in contact with a page shaper 97 and is guided along an inclined surface thereof. As in 9A shown on the pen 1d locked wire 3 (please refer 1 and 9B ) to the circumference of the magnetic pole 2 guided. As in 9B shown, the wire becomes 3 at the pin 1d on a side surface of the magnetic pole 2 in the circumferential direction of the multi-pole armature 1 along the annular part 1a wound.

In the process of 180-degree rotation of the flyer 4 from the position vertically lower than the magnetic pole 2 to the position vertically higher than the magnetic pole 2 comes through the flyer 4 fed wire 3 in contact with a page shaper 97 (please refer 1 ) and is guided along an inclined surface thereof. As in 9C shown, comes through the flyer 4 fed wire 3 in contact with the lower miter former 16 , slides off the inclined surface of the center former 16 and is from the end part 16a to a lower surface of the magnetic pole 2 in the axial direction of the multi-pole armature 1 guided. The to the bottom surface of the magnetic pole 2 guided wire 3 becomes on the lower surface of the magnetic pole 2 along the annular part 1a wound. Although not shown, the along the inclined surface of the side former 97 guided wire 3 on a side surface of the magnetic pole 2 in the circumferential direction of the multi-pole armature 1 along the annular part 1a wound. This way, with a turn of the flyer 4 the wire 3 with one turn on the magnetic pole 2 along the annular part 1a wound.

Every time the wire 3 with one turn on the magnetic pole 2 is wound, drives the transverse mechanism 18 (please refer 1 ) the transverse motor 50 on to the exercise table 21 together with the flyer 4 in a winding direction (the radial direction of the multi-pole armature 1 , ie the direction of the axis of rotation C of the flyer 4 (the X-axis direction)) away from the multi-pole armature 1 over a distance corresponding to the wire diameter of the wire 3 to move.

The center shaper movement mechanism 17 is at the exercise table 21 assembled. When the exercise table 21 over a distance corresponding to the wire diameter of the wire 3 is moved, also move the Mittenformer movement mechanism 17 and the upper center former 15 in the winding direction (the radial direction of the multi-pole armature 1 , ie the direction of the axis of rotation C of the flyer 4 (the X-axis direction)) over a distance corresponding to the wire diameter of the wire 3 , That means that in the following process of the 180-degree turn of the flyer 4 from the position vertically higher than the magnetic pole 2 to the position vertically lower than the magnetic pole 2 for forming a second turn subsequent to the first turn, the upper center shaper 15 is at a position in the winding direction by a distance corresponding to the wire diameter of the wire 3 is moved.

In this state, in which the upper central shaper 15 by a distance corresponding to the wire diameter of the wire 3 was retired, the flyer turns 4 180 degrees from the position vertically higher than the magnetic pole 2 to the position vertically lower than the magnetic pole 2 , During this rotation comes through the flyer 4 fed wire 4 in contact with the upper center former 15 and slides off the inclined surfaces of the center former 15 , As in 10A shown, allows the upper central shaper 15 an oriented winding by passing the wire 3 from the end parts 15c . 15d to one of the first turn at the magnetic pole 2 subsequent position.

It will be one of the pair of formers 15a . 15b of the upper central shaper 15 to the radially inner or outer side of the multi-pole armature 1 shifted relative to the other. In particular, the shaper plate 15b moving downstream in one direction of the flyer 4 is positioned in a direction of movement of the flyer 4 relative to the former plate 15a moving upstream in the direction of the flyer 4 is positioned, moved. 10A shows a case in which the former plate 15b which are downstream in the direction of the flyer 4 is positioned to the radially outer side of the multi-pole armature 1 relative to the former plate 15a moving upstream in the direction of the flyer 4 is positioned during the winding of the first layer is shifted.

The pair of shaper plates 15a . 15b is on the actuator plates 44a . 44b attached (see 5 and 6 ), with the operating rods 46a . 46c are connected. A shift between the pair of forming plates 15a . 15b is achieved by moving one or both actuating rods 46a . 46c of the center shaper movement mechanism 17 in the X-axis direction together with the actuator plate 44a and / or the actuator plate 44b as in 2 shown achieved.

If such a shift between the pair of former plates 15a . 15b takes place, prevents the shaper plate 15a moving upstream in the direction of the flyer 4 is positioned that the first turn of the wire 3 to the radially outer side of the multi-pole armature 1 is moved. The shaper plate 15b which are downstream in the direction of the flyer 4 is positioned, leads the wire 3 from the end parts 15c . 15d to one of the first turn at the magnetic pole 2 subsequent position when the wire 3 from the inclined surfaces of the center former 15 slides ( 10B ).

Thereafter, in the second half of the winding of the second turn, the flyer rotates 4 again 180 degrees from the position vertically lower than the magnetic pole 2 to the position vertically higher than the magnetic pole 2 , In this process also moves the lower central shaper 16 in the winding direction (the radial direction of the multi-pole armature 1 , ie the direction of the axis of rotation C of the flyer 4 (the X-axis direction)) by a distance corresponding to the wire diameter of the wire 3 as in 10C shown. In this state, in which the lower central shaper 16 by a distance corresponding to the wire diameter of the wire 3 was retired, the flyer turns 4 180 degrees from the position vertically lower than the magnetic pole 2 to the position vertically higher than the magnetic pole 2 , During this rotation comes through the flyer 4 fed wire 3 in contact with the lower center former 16 and slides off the inclined surface of the center former 16 , The center shaper 16 allows an aligned winding by holding the wire 3 from the end part 16a to one of the first turn at the magnetic pole 2 subsequent position leads.

In conjunction with the rotation of the flyer 4 the opposite shaper moves 80 who is the center shaper 15 is opposite, in the radial direction of the multi-pole armature 1 along with the pair of center shapers 15 . 16 , When the couple of middle shapers 15 . 16 to the outside (front) in the radial direction of the multi-pole armature 1 moves, the opposite shaper becomes 80 in correspondence with the displacement between the pair of shaper plates 15a . 15b inclined. As in 10A shown is the flat plate 80a arranged so that they the misaligned end portions 15c . 15d the pair of shaper plates 15a . 15b opposite, with the flat plate 80a and the misaligned end parts 15c . 15d the wire 3 with a slight gap. In this state, the opposite shaper moves 80 outward in the radial direction of the multi-pole armature 1 along with the pair of center shapers 15 . 16 ,

The opposite shaper 80 is determined by the in 1 shown rotating mechanism 82 turned. In a state where the turned flat plate 80a the misaligned end parts 15c . 15d the pair of shaper plates 15a . 15b is opposite, the opposite shaper 80 through the in 2 shown counter-former movement mechanism 83 emotional.

By repeating such winding, the pair of center shapers move 15 . 16 and the opposite shaper 80 sequentially away from the multipole anchor 1 by a distance corresponding to the wire diameter of the wire 3 if the flyer 4 moved in the direction of its axis of rotation.

The winding proceeds by wire in accordance with the wire diameter of the wire 3 is fed, and is per turn of the flyer 4 performed by the pair of center shapers 15 . 16 and the opposite shaper 80 who has the wire 3 to the magnetic pole 2 leads, along with the flyer 4 to be moved. As in 11A . 11B and 11C shown, the wire becomes 3 on the magnetic pole 2 wound with a so-called oriented winding, so that the turns in close contact with each other in the radial direction of the multi-pole armature 1 are. In this way, the first winding layer at the magnetic pole 2 educated.

When winding the first layer, the pair of center shapers 15 . 16 in the X-axis direction (the direction of the rotation axis C of the flyer 4 ) moves, the end parts can 15c . 15d . 16a in contact with a flange 2a come before wrapping the first layer of 11A . 11B and 11C is completed. In this case, the pair of center shapers 15 . 16 in the axial direction of the multi-pole armature 1 moved just before the end parts 15c . 15d . 16a in contact with the flange 2a come. This can cause a contact between the end parts 15c . 15d . 16a and the flange 2a can be prevented and then an aligned winding of the first layer can be continued.

The center shapers 15 . 16 be in the axial direction of the multipole anchor 1 moved by the operating rod 46d of the center shaper movement mechanism 17 in the axial direction of the actuating rod 46d is advanced. Because the cam plate 35a with the operating rod 46d connected is also the cam plate 35a along with the advancement of the operating rod 46d advanced. The handrails 39a . 39b move in the vertical direction along the vertical long holes 34c . 34d away from each other. Because the vertically moving plates 38a . 38b on the handrails 39a . 39b fixed, the vertically moving plates move 38a . 38b in the vertical direction (in which the vertically long holes 34c . 34d extend) away from each other along with the mutually away movements of the support rods 39a . 39b , Because the pair of upper and lower middle shaper 15 . 16 on the vertically moving plates 38a . 38b is mounted, move the center shaper 15 . 16 away from each other in conjunction with the mutually away movements of the vertical movement plates 38a . 38b , As a result, an aligned winding of the first layer can be continued. The winding of the first layer is at a contact between the wire 3 and the flange 2a of the magnetic pole 2 completed.

When winding the first layer, the opposite shaper 80 in the X-axis direction (the direction of the rotation axis C of the flyer 4 ) along with the pair of center shapers 15 . 16 moved, the flat plate can 80a in contact with the flange 2a come before the winding of the first layer is completed. In this case, the opposite shaper 80 in the axial direction of the multi-pole armature 1 moved just before the flat plate 80a in contact with the flange 2a comes. This can cause a contact between the flat plate 80a and the flange 2a can be prevented and then an aligned winding of the first layer can be continued. The opposite shaper 80 can therefore in the axial direction of the multi-pole armature 1 by the Z-axis expandable / contractible actuator 86 the Opposite Shaper Movement Mechanism 83 to be moved.

After completing wrapping the in 11A . 11B and 11C Subsequently, the winding of the second layer is carried out. When winding the second layer is while the wire 3 around the magnetic pole 2 by turning the flyer 4 in the same direction as the first layer is wrapped, the flyer 4 to the multi-pole anchor 1 moved by the transverse motor 50 is rotated in the direction opposite to the direction of rotation during the winding of the first layer. Along with the movement of the flyer 4 also become the middle forms 15 . 16 in a similar way to the multipole anchor 1 as in 12A . 12B and 12C shown moved.

To start winding the second layer, the pair of center shifters moves 15 . 16 to the multi-pole anchor 1 as indicated by the solid arrows in 12B indicated from the in 11A . 11B and 11C shown states. Once the end parts 15c . 15d . 16a from the flange 2a are spaced, the distance between the pair of Mittenformern 15 . 16 reduced. The end parts 15c . 15d . 16a close the on the magnetic pole 2 Wrapped first winding layer in the Z-axis direction with a small gap between them. In this way, stable oriented winding of the second layer can be achieved by guiding the wire 3 to the magnetic pole 2 be performed.

When winding the second layer, the rotating flyer moves 4 in the direction opposite to the direction of movement during the winding of the first layer. Every time the wire 3 in the second layer with one turn on the magnetic pole 2 is wound, he crosses the wire 3 in the underlying first layer once. If the wire 3 in an upper layer the wire 3 Crosses in a lower layer, the first rides over the second wire.

The multipole anchor 1 includes the plurality of magnetic poles 2 radially in the circumferential direction of the multi-pole armature 1 are arranged. When the winding is at a magnetic pole 2 voluminous in the circumferential direction of the multi-pole armature 1 This results in restrictions on the winding at magnetic poles adjacent to the circumference 2 , What the quadrangular cross sections of the magnetic poles 2 When it comes to forming a plurality of winding layers on a magnetic pole 2 to prefer that wire 3 in an upper layer and the wire 3 in a lower layer from the axial direction of the multi-pole armature 1 seen crossing each other.

In the winding method according to this embodiment, the direction of displacement is between the pair of forming plates 15a . 15b during winding of the second layer, opposite to that during winding of the first layer. In particular, as in 12A shown the shaper plate 15b which are downstream in the direction of the flyer 4 is positioned to the radially inner side of the multi-pole armature 1 relative to the former plate 15a moving upstream in the direction of the flyer 4 is positioned, moved.

The pair of shaper plates 15a . 15b is on the actuator plates 44a . 44b (please refer 5 and 6 ) attached to the operating rods 46a . 46c are connected. A shift between the pair of forming plates 15a . 15b is achieved by one or both actuating rods 46a . 46c of the center shaper movement mechanism 17 in the X-axis direction together with the actuator plate 44a and / or the actuator plate 44b be moved.

If such a shift between the pair of former plates 15a . 15b takes place, slides through the flyer 4 fed wire 3 from the inclined surfaces of the former plates 15a . 15b and is in a tilted state from the end parts 15c . 15d on the first winding layer at the magnetic pole 2 guided. If the wire 3 in the second layer is guided in a tilted state, he crosses the wire 3 in the underlying first layer. Therefore, in this embodiment, the wire 3 in an upper layer the wire 3 in a lower layer from the axial direction of the multi-pole armature 1 cross seen.

In conjunction with the rotation of the flyer 4 during the winding of the second layer, the opposite former moves 80 in the radial direction of the multi-pole armature 1 along with the pair of center shapers 15 . 16 while he is the center shaper 15 opposite. When the couple of middle shapers 15 . 16 inward (back) in the radial direction of the multipole anchor 1 moves, the opposite shaper becomes 80 in correspondence with the displacement between the pair of shaper plates 15a . 15b so inclined that the flat plate 80a the end parts 15c . 15d along the slopes of the pair of shaper plates 15a . 15b with a space in between that is slightly larger than the wire diameter of the wire 3 is opposite.

In this state, the opposite shaper moves 80 inward in the radial direction of the multipole anchor 1 along with the pair of center shapers 15 . 16 and will be the one by the flyer 4 fed wire 3 while being wound up between a middle shaper 15 and the opposite former 80 to the magnetic pole 2 to be led. The opposite shaper 80 is through the rotating mechanism 82 turned (see 1 ) and by the opposing former movement mechanism 83 moved (see 2 ).

As in 12B shown slides through the flyer 4 fed wire 3 from each of the inclined faces of the former plates 15a . 15b of the upper central shaper 15 and becomes the magnetic pole 2 while passing through the molding plates 15a . 15b and the opposite former 80 is included. If the wire 3 to the magnetic pole 2 is guided, the wire becomes 3 guided on the first winding layer, while the inclined state is maintained, so that it does not sink into the intermediate wire recesses of the underlying layer. The wire 3 So in the second layer can be the wire 3 in the underlying first layer reliably on a surface of the magnetic pole 2 opposite the upper central former 15 cross.

As the second layer is wound, the lower center former also moves 16 in the winding direction (the radial direction of the multi-pole armature 1 , ie the direction of the axis of rotation C of the flyer 4 (the X-axis direction)) over a distance corresponding to the wire diameter of the wire 3 per revolution of the flyer 4 as in 12C shown. In the process of 180-degree rotation of the flyer 4 from the position vertically lower than the magnetic pole 2 to the position vertically higher than the magnetic pole 2 comes through the flyer 4 fed wire 3 in contact with the lower center former 16 and slides off the inclined surface of the center former 16 , The center shaper 16 allows aligned winding of the second layer by guiding the wire 3 from the end part 16a to a position subsequent to a previously wound turn of the wire in the first winding layer. As in 13A . 13B and 13C shown, the winding of the second layer at a contact between the wound wire 3 and the annular part 1a completed.

Then, the winding of the third layer is performed. The winding of the third layer is performed in the same procedure as the winding of the first layer. The winding of the fourth layer is performed by the same procedure as the winding of the second layer. Therefore, a redundant description of this winding is omitted here.

When the desired winding at the magnetic pole 2 is completed, the indexing engine 9 operated to the multipole anchor 1 to turn and another magnetic pole 2 to place at the winding position, then the winding is started again. Completing the winding at all magnetic poles 2 marks the end of the winding process on the multi-pole anchor 1 ,

In this embodiment, when there are multiple layers of winding at each magnetic pole 2 of the multipolar anchor 1 can be formed, the winding can be performed such that the wire 3 in an upper layer the wire 3 in a lower layer on surfaces of the magnetic pole 2 crosses the axial direction of the multipole anchor 1 cross. It is at each of the surfaces of the magnetic poles 2 that the circumferential direction of the multi-pole armature 1 cross, carried out an aligned winding, so so the turns of the wire 3 in each layer are parallel to each other and there is no gap between them. Furthermore, the wire 3 in an upper layer parallel to the wire 3 in a lower layer and sinks into the intermediate wire pits of the lower layer.

Therefore, the winding thickness is at each of the surfaces of the magnetic poles 2 that the circumferential direction of the multi-pole armature 1 do not cross, because it is smaller than twice the wire diameter. So although the multitude of magnetic poles 2 radially in the circumferential direction of the multi-pole armature 1 can be arranged, winding at a magnetic pole 2 Therefore, restrictions on the winding of adjacent magnetic poles along the circumference are not imposed 2 yield, and can the number of turns of the wire 3 at each magnetic pole 2 be wound can be increased.

According to the above-described embodiments, the upper center shaper is made 15 from the pair of former plates 15a . 15b , Although not shown, may also be the lower central shaper 16 consist of a pair of shaper plates. If the lower central shaper 16 consists of a pair of forming plates, the winding can be performed such that the wire 3 in an upper layer the wire 3 in a lower layer on surfaces of the magnetic poles 2 , which is the axial direction of the multi-pole armature 1 crosses, in which one of the pair of forming plates to the radially inner or outer side of the multi-pole armature 1 relative to the other is shifted when the pair of center shapers 15 . 16 outward in the radial direction of the multi-pole armature 1 moved, and by one of the pair of forming plates to the radially inner or outer side of the multi-pole armature 1 relative to the other is shifted when the pair of center shapers 15 . 16 inward in the radial direction of the multipole anchor 1 emotional.

Preferably, the flyer winding machine further comprises: an opposing former disposed opposite one of the pair of center formers; an opposing former-movement mechanism configured to cause the opposing former to co-exist with one of the pair of center formers in the radial direction of the multipolar armature in conjunction with the rotation of the flyer emotional; and a rotation mechanism configured to cause the opposing shaper to rotate in correspondence with the displacement between the pair of shaper plates.

Preferably, the center shaper moving mechanism includes: a first operating rod and a second operating rod each connected to the pair of shaper plates and capable of moving in the direction of a rotation axis of the leaflet; a third operating rod, which is connected to the other of the pair of Mittenformern and can be moved in the direction of the axis of rotation of the flyer; and a moving device configured to allow the first to third actuating rods to move separately and independently of each other.

Another embodiment relates to improvements in a winding method for winding a wire on each magnetic pole of a multi-pole armature using a winding machine comprising a flyer and a pair of center shaper, wherein the flyer is configured to wind the wire onto the magnetic pole as it turns the magnetic pole rotates and reciprocates in a radial direction of the multi-pole armature, the pair of center formers being arranged to enclose the magnetic pole in an axial direction of the multi-pole armature, and configured to guide the wire fed from the flyer from vertex sides to the magnetic pole as they move back and forth outward and inward in the radial direction of the multipolar anchor in conjunction with the flyer's reciprocation.

One of the pair of center shapers consists of a pair of shaper plates that overlap each other in a circumferential direction of the multi-pole armature. The winding method includes: when the pair of center shapers move outwardly in the radial direction of the multipolar armature, shifting one of the pair of former plates to a radially inner or outer side of the multipolar armature relative to the other of the pair of former plates; and when the pair of center shifters move inward in the radial direction of the multipolar armature, a different one of the pair of shaper plates to the radially inner or outer side of the multi-pole armature relative to the other of the pair of shaper plates.

Preferably, the winding method further comprises: causing an opposing former plate facing one of the pair of center formers to reciprocate inwardly and outwardly together with the pair of center formers in the radial direction of the multipolar armature in conjunction with the rotation of the flyer emotional; when the pair of center shapers move outward in the radial direction of the multipolar armature, tilting the opposing former along inclinations of the pair of shaper plates after shifting one of the pair of shaper plates to the radially inner or outer side of the multi-pole armature, and causing that the inclined opposed former moves outward together with the pair of center formers in the radial direction of the multipolar armature; when the pair of center shapers move inward in the radial direction of the multipolar armature, tilting the opposed former along the inclinations of the pair of shaper plates after shifting one of the pair of shaper plates to the radially inner or outer side of the multi-pole armature and causing it the inclined opposed former moves inwardly along with the pair of center formers in the radial direction of the multi-pole armature; and winding the wire fed by the flyer onto the magnetic pole by passing the wire from between the one of the pair of center formers and the opposed former to the magnetic pole.

In the flyer winding machine and the winding method according to the above embodiments, one of the pair of center formers is composed of the pair of forming plates, and one of the forming plates is displaced in the radial direction of the multipolar armature relative to the other of the forming plates. Once the wire has slid from the inclined surfaces of the former plates, the wire is guided and inclined with respect to a center axis of a magnetic pole. When the wire guided in this inclined state belongs to an upper layer, the wire may cross the wire in a lower layer.

Since one of the center shaper is disposed in the axial direction of the multi-pole armature, the wire in an upper layer crosses the wire in a lower layer as viewed from the axial direction of the multi-pole armature. Thereby, the wire in the upper layer can be prevented from crossing the wire in the lower layer as viewed from the circumferential direction of the multi-pole armature.

The opposite shaper faces one of the center shaper in correspondence with the displacement between the pair of shaper plates. Thus, as soon as the wire has slid from the inclined surfaces of the former plates of one of the center formers, the wire is guided to the magnetic pole and thereby trapped by the former plates and the opposite former. When the wire is guided on a lower winding layer while maintaining its inclined state, the wire in an upper layer can reliably intersect the wire in the lower layer at a surface facing one of the center shaper.
