Description

  The present invention mainly relates to a 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 winds 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 multipole armature Required. For this purpose, so-called aligned winding, in which the wires adjacent to the magnetic poles are aligned without gaps, is effective. For this purpose, in the flyer type winding machine, a pair of center formers arranged so as to sandwich the magnetic pole from the axial direction of the multipole armature, and arranged so as to sandwich the magnetic pole from the circumferential direction of the multipolar armature. What is provided with a pair of side plates parallel to each other is known (for example, see Patent Document 1).

  That is, in this flyer type winding machine, the center former sandwiches the magnetic pole to be wound by the multipole armature from the axial direction of the multipole 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. On the other hand, the side plate sandwiches the magnetic pole to be wound of the multipole armature from the circumferential direction of the multipole armature, thereby winding the wire fed from the flyer from the tip facing the inner peripheral side of the multipole armature. Guide to the desired position of the power pole. The flyer that feeds the wire while rotating is moved in the direction of the rotation axis together with the center former and the side plate, whereby the aligned winding is performed.

  Here, a specific description will be given of the case where the wire is wound around the magnetic poles over a plurality of layers. First, the tips of the center former and the side plate are advanced to the inner peripheral side of the multipole armature, The flyer is rotated from the state to feed out the wire, and the flyer is moved together with the center former and the side plate toward the outside of the multipole armature to perform the first layer winding. When the wire is in contact with the outer peripheral side flange of the magnetic pole, the first layer winding is finished, and then the second layer is the center former and the side plate opposite to the first layer winding. Winding by moving in the direction. The center former and the side plate are arranged so that the second layer is wound on the first layer coil by moving away from the outer peripheral side of the magnetic pole toward the inner peripheral side while guiding the wire. Yes, when the tip of each of the center former and side plate moves to the inner circumference side of the magnetic pole, the third layer is wound by reversing the moving direction. The layer is also wound.

  However, as shown in FIG. 22, since the flange 201a that defines the winding width of the winding is formed on the outer peripheral side of the magnetic pole 201, the pair of side plates 202, 202 parallel to each other has the outer peripheral flange 201a. The multi-pole armature 200 is sandwiched from the circumferential direction, and the side plate 202 has a problem of approaching the adjacent magnetic pole 201. That is, there is no problem when the number of magnetic poles 201 is a relatively small number of multipolar armatures 200 such as 4 to 6, but the number of magnetic poles 201 is 12 or 18 or more. In the case of the armature 200, the angle formed by one magnetic pole 201 on which the winding is performed and the magnetic pole 201 adjacent to the magnetic pole 201 is small, and the two approach each other. For this reason, when the winding 203 has already been formed on the magnetic pole 201 adjacent to the magnetic pole 201 on which the winding is performed, a pair of mutually parallel pairs sandwiching the outer peripheral side flange 201a from the circumferential direction of the multipole armature 200 When the side plates 202, 202 move in the direction of the rotation axis of the flyer and move toward the inner peripheral side of the multipole armature 200 as indicated by solid arrows, the tips of the side plates 202 that guide the wire to the magnetic pole 201 are adjacent to each other. The side plate 202 cannot sufficiently enter the inner peripheral side of the magnetic pole 201 to be wound by contacting the already formed winding 203 of the magnetic pole 201 to be wound. Then, the guide of the wire to the magnetic pole 201 by the side plate 202 is not performed on the inner peripheral side of the magnetic pole 201, and there is a possibility that the wire cannot be guided to the portion where the wire is originally intended to be wound on the inner peripheral side. .

  In order to eliminate this point, as shown in FIG. 23, a pair of side plates 202 and 202 that sandwich the outer peripheral flange 201 a from the circumferential direction of the multipolar armature 200 are directed toward the inner peripheral side of the multipolar armature 200. As shown in FIG. 2, the side plates 202 and 202 are inclined with respect to the rotation axis of the flyer as indicated by solid and broken arrows along the inclination angle. It is possible to move it diagonally. By inclining the pair of side plates 202, 202 with respect to the rotation axis of the flyer, the tip toward the inner peripheral side of the multipole armature 200 contacts the already formed winding 203 of the adjacent magnetic pole 201. Without making it possible, the pair of side plates 202, 202 can be advanced to the inner peripheral side of the magnetic pole 201 to be wound in the first layer winding. When the first layer is wound, the side plate 202 enters the inner periphery of the magnetic pole to be wound, so that the wire is actually wound at the tip of the side plate 202 that guides the wire. Therefore, it can be expected that the wire is surely guided to the portion where the wire is originally intended to be wound.

  However, if the side plate 202 is inclined with respect to the rotation axis of the flyer, it is necessary to move the side plate 202 obliquely with respect to the rotation axis of the flyer along the inclination angle. Then, when further winding the second layer on the first layer wound on the magnetic pole 201, the tip of the side plate 202 comes into contact with the first layer, and the second layer At the time of winding the eye, the side plate 202 cannot be moved to the inner peripheral side of the magnetic pole 201. Further, if the third layer is to be wound, the tip of the side plate 202 is further in contact with the second layer, and the entry distance of the side plate 202 entering the inner peripheral side of the magnetic pole 201 is further shortened. Become. Thus, the approach distance of the side plate 202 is sequentially shortened in accordance with the upper layer winding, and there is still a problem to be solved that the wire cannot be guided to the portion to be originally wound on the inner peripheral side of the upper layer winding. It remained.

  The object of the present invention is to stabilize the wire rod in the magnetic pole not only in the first layer but also in the winding of the second and subsequent layers by sufficiently making the tip of the side plate enter the inner peripheral side of the magnetic pole. Another object of the present invention is to provide a winding apparatus and a winding method that can be aligned and wound.

  The present invention relates to a flyer that draws a wire while rotating around a magnetic pole in a multipole armature and winds the wire around the magnetic pole, and a flyer that is disposed so as to sandwich the magnetic pole from the axial direction of the multipole armature. A pair of center formers for guiding the wire drawn from the magnetic pole to the magnetic pole, and a pair of side plates arranged to sandwich the magnetic pole from the circumferential direction of the multipole armature and guiding the wire drawn from the flyer to the magnetic pole. This is an improvement of the winding device.

  The characteristic configuration is that the pair of side plates are inclined with respect to the rotation axis of the flyer so that the distance from each other becomes closer toward the inner periphery of the multipole armature, and the inclination angle with respect to the rotation axis of the flyer is changed. Thus, the distance between the tips facing the inner peripheral side of the multipole armature can be changed.

  In this case, it is preferable that concave grooves into which the outer peripheral side flanges of the magnetic poles enter can be formed on the opposing surfaces of the pair of side plates so as to extend in the direction of the rotation axis of the flyer. It is preferable that the support member is provided so as to be movable in the direction of the rotation axis of the flyer, and the pair of side plates are pivotally supported by the side plate support member.

  Then, when the side plate support member moves away from the magnetic pole, the inclination angle of the pair of side plates with respect to the rotation axis of the flyer is reduced, and the tip interval between the pair of side plates is increased, and when the side plate support member approaches the magnetic pole, Plate angle changing means for decreasing the tip interval between the pair of side plates while increasing the inclination angle of the side plate with respect to the rotation axis of the flyer can also be provided.

  The plate angle changing means preferably includes a pressing member that contacts the outer end surface of the magnetic pole, and side plate urging means that urges the pair of side plates so that the pair of side plates sandwich the pressing member. The plate angle changing means includes a plate-like member that overlaps with the side plate support member at a predetermined interval on the magnetic pole side of the side plate support member and is movable independently of the side plate support member in the rotation axis direction of the flyer. The plate-like member urging means for urging the side plate support member and the plate-like member so as to increase the distance between them can be further provided. In this case, the plate-like member is provided with a pressing member.

  The winding method of the present invention is such that a wire rod is drawn out while rotating around a magnetic pole in a multipole armature, and the wire is wound around the magnetic pole, and the magnetic pole is sandwiched from the axial direction of the multipole armature. A pair of center formers that guide the wire rod that is arranged and fed from the flyer to the magnetic pole, and a pair of sides that guide the wire rod fed from the flyer that is arranged so as to sandwich the magnetic pole from the circumferential direction of the multipole armature. In this winding method, a wire rod is wound around each magnetic pole of a multipole armature using a winding device including a plate.

  The characteristic point is that the pair of side plates are inclined with respect to the rotation axis of the flyer so that the distance from each other becomes closer toward the inner peripheral side of the multipole armature, and the pair of side plates with respect to the rotation axis of the flyer is wound during winding. This is to change the tip end interval facing the inner peripheral side of the multipole armature by changing the inclination angle of the plate.

  Specifically, when the pair of side plates move from the inner peripheral side to the outer peripheral side of the multipole armature, the tip end distance between the pair of side plates is increased while reducing the inclination angle of the pair of side plates with respect to the rotation axis of the flyer. Winding that decreases the tip interval between the pair of side plates while increasing the inclination angle of the pair of side plates with respect to the rotation axis of the flyer when the pair of side plates moves from the outer peripheral side to the inner peripheral side of the multipole armature. Is the method.

  In the case of a winding method in which multiple layers of wire are wound around the magnetic pole, the pair of center formers are moved over the entire winding width of the magnetic pole when winding all layers, and at least when the first layer is wound. The side plate is moved over the entire winding width of the magnetic pole together with the pair of center formers with the tips thereof aligned with the tips of the pair of center formers. The pair of side plates can be moved together with the pair of center formers in a state where the ends of the pair of side plates coincide with the ends of the pair of center formers in at least a part of the entire winding width.

  On the other hand, in the case of a winding method in which a plurality of layers of wire are wound around the magnetic pole, a pair of center formers are moved over the entire winding width of the magnetic pole when winding all layers, and at least the first layer winding Sometimes the pair of side plates are moved over the entire winding width of the magnetic pole together with the pair of center formers with their tips aligned with the tips of the pair of center formers. When the gap between the wound wire and the winding formed on the adjacent magnetic pole is less than the wire diameter of the wire, the wire formed on the magnetic pole wound adjacent to the magnetic pole within the total winding width of the magnetic pole was formed. It is also possible to move the pair of side plates together with the pair of center formers with their tips aligned with the tips of the pair of center formers in at least a part of the gap between the windings exceeding the wire diameter of the wire rod.

  In the winding machine and winding method of the present invention, since the pair of side plates are inclined with respect to the rotation axis of the flyer, even if the pair of side plates sandwich the outer peripheral side flange of the magnetic pole, the rotation axis of the flyer By moving the pair of side plates obliquely, the end of the side plate facing the inner periphery of the multipole armature is wound without contacting the already formed windings of the adjacent magnetic poles. It can be made to approach to the inner peripheral side of the magnetic pole. For this reason, by moving the pair of side plates together with the pair of center formers over the entire winding width of the magnetic poles with the tips of the pair of side plates aligned with the tips of the pair of center formers, The wire rod can be guided to the magnetic pole by both the center former and the pair of side plates, which enables stable alignment winding.

  Then, the inclination angle is changed so that the distance between the tip ends of the pair of side plates facing the inner peripheral side of the multipole armature can be changed. Even when trying to wind the upper layer further, the pair of side plates are inserted into the inner circumference side of the magnetic pole while the lower layer winding is sandwiched between them by widening the distance between the tips of the pair of side plates. Can be made. Therefore, in the winding machine and winding method of the present invention, not only the first layer but also the second and subsequent layers are wound, the end of the side plate sufficiently enters the inner peripheral side of the magnetic pole. The side plate can be used to guide the wire to the magnetic pole, thereby enabling stable alignment winding.

  In this case, when the pair of side plates moves from the outer peripheral side to the inner peripheral side of the multipole armature, the tip end distance between the pair of side plates is decreased while increasing the inclination angle of the pair of side plates with respect to the rotation axis of the flyer. The tip of each of the pair of side plates facing the inner peripheral side of the multipole armature draws an arc shape to narrow the distance between each other. For this reason, compared with the case where the side plate is moved linearly without changing the tilt angle, the distance to reach the inner peripheral side of the magnetic pole without bringing the tip of the side plate into contact with the lower layer winding is reduced. Can be increased.

  On the other hand, since the magnetic poles are provided radially in the multipole armature, the gap between adjacent magnetic poles is narrowed on the inner peripheral side. For this reason, when the winding of the first layer or more is formed, the gap between the wire wound around the magnetic pole and the winding formed on the adjacent magnetic pole is less than the wire diameter of the wire on the inner peripheral side Occurs. Then, winding around the gap on the inner peripheral side becomes impossible. However, on the outer peripheral side, if the gap between the wire wound around the magnetic pole and the winding formed on the adjacent magnetic pole exceeds the wire diameter of the wire, further winding is possible on the outer peripheral side. It is. Therefore, at the time of winding of the second and subsequent layers, a part of the total winding width of the magnetic pole, specifically, the magnetic pole adjacent to the wire wound around the magnetic pole within the total winding width of the magnetic pole was formed. By moving the pair of side plates together with the pair of center formers in a state where the tips of the pair of side plates are aligned with the tips of the pair of center formers in a part on the outer peripheral side of the armature where the gap between the windings exceeds the wire diameter of the wire rod In a part of the range, the wire rod is guided to the magnetic pole by both the pair of center formers and the pair of side plates, thereby enabling more stable aligned winding.

  And, if the concave grooves into which the outer peripheral side flanges of the magnetic poles can enter are formed on the opposing surfaces of the pair of side plates so as to extend in the rotation axis direction of the flyer, the strength of the side plates is ensured between the magnetic poles and the magnetic poles. Decreasing the thickness of the entering side plate, increasing the distance between the side plate and the winding material formed on the adjacent magnetic pole, and a part of the total winding width that can guide the wire by the side plate. The range can be expanded.

The multipole armature 1 is placed on the index table 11 with the shaft 11a of the index table 11 inserted through the through hole 1c of the annular portion 1a. At the same time, the multipole armature 1 is pressed against the index base 11 from an opposite direction (upward in FIG. 1) to the index base 11 by an armature pressing member 96 described later. Thereby, the multipole armature 1 is configured to be supported on the index base 11.

The first head 22 supports a cylindrical first spindle shaft 24 that is rotatable via a bearing 23, and a first central body 26 that cannot rotate through a bearing 25 on the inner periphery of the first spindle shaft 24. (The structure that makes the first central body 26 non-rotatable will be described later). An annular flange portion 24a is integrally provided at the tip of the first spindle shaft 24 facing the multipole armature 1, and a flyer 4 extending toward the multipole armature 1 is attached to the flange portion 24a.

A first cam 45 whose tip is formed in a tapered shape 45 a (FIG. 2) is connected to the end of the first rod 44. The first rod 44 is formed in a hollow cylindrical shape, and a second rod 47 is slidably inserted therein. This second rod 47 is spline-engaged with the first rod 44 and is movable in the direction of the rotation axis of the flyer 4 but is not rotatable. A center former support plate 33 that supports the center formers 15 and 16 is attached to the distal end surface of the first central body 26.

  As shown in FIGS. 2 to 5, a guide rail 34 extending in the rotation axis direction (Z-axis direction) of the multipolar armature 1 is provided on the front surface of the center former support plate 33 facing the multipolar armature 1. The guide rail 34 is engaged with a pair of vertical movement plates 35 a and 35 b that are movable along the guide rail 34. The pair of vertical moving plates 35a and 35b are urged in a direction approaching each other by a spring 36 as an elastic member connected to both. Center formers 15 and 16 that sandwich the magnetic pole 2 from the Z-axis direction are attached to the pair of vertical moving plates 35 a and 35 b at positions symmetrical to each other about the rotation axis of the flyer 4.

  As shown in FIG. 2, one center former 15 at the upper side is formed in a substantially L-shape that extends forward from the vertical moving plate 35 a toward the multipolar armature 1 and then goes downward. The outer surface leading to is formed into a curved surface. Also, as shown in FIG. 4, the tip of one center former 15 is formed to taper downward, and the width H of the tapered portion 15a toward the lower side is the width W ( It is formed substantially equal to FIG. Then, the wire 3 fed from the flyer 4 is polished and finished so that it slides down along the curved surface of the center former 15 and is guided to the magnetic pole 2 from the tip 15a at the tip.

  On the other hand, as shown in FIG. 2, the other center former 16 is also formed in a substantially L-shape that extends forward from the vertical movement plate 35b and then moves upward, and the outer surface from the lower surface to the front surface is formed in a curved shape.

Sliders 32b and 32b are movably provided on the rails 32a and 32a, respectively, and attachment members 32c are provided on the sliders 32b and 32b, respectively. Then, the side plate support member 37 is bridged and fixed to the attachment members 32c and 32c of the side walls 32 and 32 on both sides in the Y-axis direction so as to be parallel to the center former support plate 33.

  As shown in FIGS. 2 and 3, a fixing member 47 a is attached to the armature 1 side end of the second rod 47, and the fixing member 47 a is fixed to the side plate support member 37. In this way, the armature 1 side end of the second rod 47 is fixed to the side plate support member 37 via the fixing member 47a, and the side plate support member 37 is moved to the center former by the movement of the second rod 47. It is configured to be movable in the direction of the rotation axis of the flyer 4 independently of the support plate 33. A pair of side plates 39, 39 sandwiching the magnetic pole 2 from the circumferential direction of the multipole armature 1 are disposed on the side plate support member 37 at positions symmetrical with respect to the rotation axis of the flyer 4.

  The pair of side plates 39, 39 is a target structure, and the side view thereof will be described by representing one of them. As shown in FIG. 2, the outer edge in the side view of the side plate 39 has a tip 39b extending in the vertical direction. It is formed so as to form a straight arc and a gentle arc in the vertical direction. A straight tip 39b is formed so as to be longer than the thickness D (FIG. 6) of the magnetic pole 2, and the arcuate portion 39c in the vertical direction has a tapered shape 15a, 16a in the pair of center formers 15, 16, respectively. It is formed so as to be sandwiched from the axial direction. The outer surface and the periphery of the side plate 39 are polished and finished, and the wire 3 that has been fed out of the flyer 4 and slid along the curved surface of the center former 16 extends along the outer surface and the periphery of the side plate 39. It is configured to slide down and be guided to the magnetic pole 2.

  As shown in FIGS. 2 to 6, such a side plate 39 has a plate-like shape that sandwiches the magnetic pole 2 from the circumferential direction of the multipole armature 1, and extends through an extension member 38 that extends the entire length thereof. The side plate support member 37 is pivotally supported. The side plate support member 37 is H-shaped when viewed from the front in the X-axis direction, and both end portions in the Y-axis direction are attached to the attachment members 32c and 32c, respectively. The extension member 38 is formed with a notch 38 a into which the central portion 37 a of the side plate support member 37 enters at the rear end facing the center former support plate 33 in a side view as viewed from the Y-axis direction. The rear end 39d of the side plate 39 is attached to the front end of the extension member 38, and the entire length thereof is extended. With the central portion 37a of the side plate support member 37 entering the notch 38a, the substantially central portion of the extension member 38 is pivotally supported by the side plate support member 37 by the pivot pin 38b extending in the Z-axis direction ( FIG. 2, FIG. 3, FIG. 6). Thus, the pair of side plates 39, 39 are provided to be rotatable about the pivot pin 38b.

  The pair of side plates 39, 39, with respect to the rotation axis of the flyer 4, such that the distance from each other becomes closer toward the inner peripheral side of the multipole armature 1 in the top view shown in FIG. 3. Inclined. Then, plate angle changing means 42 is provided for changing the inclination angle of the side plate 39 with respect to the rotation axis of the flyer 4 to change the tip interval facing the inner peripheral side of the multipole armature 1.

  As shown in FIGS. 3 and 6, the plate angle changing means 42 in this embodiment includes a plate-like member 48 that overlaps the side plate support member 37 at a predetermined interval on the magnetic pole 2 side of the side plate support member 37. The pressing member 49 attached to the plate-like member 48 via the support column 49a, and the pressing member urging means 40a for urging the plate-like member 48 so that the pressing member 49 is brought into contact with the outer end surface of the magnetic pole 2 And side plate urging means 40b for urging the pair of side plates 39, 39 so that the pair of side plates 39, 39 sandwich the pressing member 49 therebetween.

  Four slide pins 48a parallel to the rotational axis of the flyer 4 are inserted into the side plate support member 37 at the four corners so as to surround the pair of side plates 39, 39, and the magnetic pole 2 of the four slide pins 48a. The side end is screwed to the plate member 48. The plate-like member 48 is formed with a pair of relatively large holes 48b, 48b into which the pair of side plates 39, 39 are separately inserted, so that the plate-like member 48 is independent of the side plate support member 37 and is used as a flyer. 4 is configured to be movable in the direction of the rotation axis. Between the side plate support member 37 and the plate-like member 48, a coil spring 40a which is a pressing member urging means for urging the gap between the side plate support member 37 and the plate-like member 48 is interposed. . Then, at the other end of the four slide pins 48a that have passed through the side plate support member 37, a stopper member 48c that prohibits the distance between the side plate support member 37 and the plate-like member 48 from being increased to a predetermined value or more (see FIG. 3) is provided.

  The pressing member 49 is a front surface facing the multipolar armature 1 of the plate-like member 48, and is attached to the rotating shaft of the flyer 4 via a support column 49 a. As shown in FIG. 6, the pressing member 49 is formed to have substantially the same width as the width in the circumferential direction of the flange portion 2 a in the magnetic pole 2. The coil spring 40a, which is a pressing member urging means for moving the plate member 48 to the armature 1 side, is operated by the urging force for increasing the distance between the side plate support member 37 and the plate member 48. The pressing member 49 is configured to abut on the outer end face of the magnetic pole 2 that is on the rotation axis 4 and is the object of winding. Since the pair of side plates 39 and 39 sandwich the magnetic pole 2 that is the object of winding, the pair of side plates 39 and 39 has the pressing member 49 in contact with the magnetic pole 2 in the width direction Y. It is configured to be sandwiched from the axial direction.

  On the other hand, the side plate urging means 40b is interposed in a compressed state between the end on the center former support plate 33 side from the pivot pin 38b which is a pivot point of the extension member 38 pivotally supported by the side plate support member 37. Coil spring 40b. Due to the force of the coil spring 40b to extend, the distance on the distal end side of the extension member 38 is narrowed, and the pair of side plates 39, 39 attached to the distal end are biased so as to approach each other. For this reason, the pair of side plates 39, 39 are configured to hold the pressing member 49 from the width direction of the magnetic pole 2 by the coil spring 40b. Here, the pair of side plates 39, 39 are provided to be inclined with respect to the rotation axis of the flyer 4 so that the distance between the side plates 39, 39 becomes closer to the tip, so that the side plates 39, 39 hold the pressing member 49. If the positions to be moved are different, the pair of side plates 39 and 39 rotate about the pivot pin 38b which is a pivot point, respectively, and the distance between the tips 39b and 39b is changed.

  Here, since the pressing member 49 does not move in contact with the magnetic pole 2 during actual winding, the position of the pair of side plates 39, 39 with respect to the pressing member 49 depends on the position of the side plate support member 37 with respect to the pressing member 49. Determined. That is, as shown in FIG. 8, the side plate support member 37 is moved away from the plate-like member 48 by the urging force of the spring 40a, and the holding member 49 is sandwiched between the tips 39b, 39b of the pair of side plates 39, 39. Then, since the space | interval in those front-end | tips 39b and 39b expands, a pair of side plate 39 and 39 rotates as shown by a solid line arrow centering on the pivot pin 38b, and the inclination angle with respect to the rotating shaft of the flyer 4 decreases. (FIG. 8 shows a case where the angle α2 in FIG. 7 decreases to α1). Conversely, when the side plate support member 37 is brought close to the plate-like member 48 against the biasing force of the spring 40a, as shown in FIG. 7, the holding member 49 on the extension member 38 side of the pair of side plates 39, 39. , The distance between the ends 39b, 39b of the pair of side plates 39, 39 is reduced, and the pair of side plates 39, 39 are rotated about the pivot pin 38b as indicated by solid arrows, The inclination angle α2 with respect to the rotation axis of the flyer 4 increases (FIG. 7 shows a case where the angle α1 in FIG. 8 increases to α2).

  Therefore, the plate angle changing means 42 including the side plate support member 37 is configured such that when the side plate support member 37 moves away from the magnetic pole 2 in the actual winding in which the pressing member 49 does not move in contact with the magnetic pole 2, As shown in FIG. 8, while the inclination angle of the pair of side plates 39, 39 with respect to the rotation axis of the flyer is reduced, the distance between the tip ends of the pair of side plates 39, 39 is increased, and the side plate support member 37 approaches the magnetic pole 2. Sometimes, as shown in FIG. 7, the tip end spacing of the pair of side plates 39, 39 is decreased while increasing the angle of inclination of the pair of side plates 39, 39 relative to the rotational axis of the flyer.

  As shown in FIG. 6, the pair of side plates 39, 39 that sandwich the magnetic pole 2 from the circumferential direction, that is, the Y-axis direction, has a concave groove 39 a that allows the outer peripheral side flange 2 a of the magnetic pole 2 to enter the opposing surface. Each is formed extending in the direction of the rotation axis of the flyer 4. The width M of the concave groove 39a in the Z-axis direction is larger than the dimension L of the flange portion 2a in the Z-axis direction so that the flange portion 2a can enter. The concave groove 39a starts from the tip 39b of the side plate 39, and the dimension N in the X-axis direction is as shown in FIG. 9, with the flange 2a entering the concave groove 39a. 39b is formed in a length that can approach the annular portion 1a.

  On the other hand, as shown in FIGS. 2 and 4, the pair of center formers 15, 16 covers the arcuate portions 39 c on both sides of the pair of side plates 39, 39 sandwiching the magnetic pole 2 from the width direction, from the vertical direction. That is, the cover portions 15b and 16b that cover the upper and lower edges of the pair of side plates 39 and 39 in FIG. 2 from the vertical direction that is the rotation axis direction of the multipole armature 1 are formed.

  Returning to FIG. 1, the traverse mechanism 18 that moves the flyer 4, the center formers 15 and 16, and the side plates 39 and 39 in the X-axis direction that is the radial direction of the multipole armature 1 is a traverse mechanism provided on the base 5. A motor 50, a ball screw 51 connected to the output shaft of the traverse motor 50 and extending in the direction of the rotation axis of the flyer 4, a moving body 52 a to which the ball screw 51 is screwed, and a ball screw 51 on the base 5. And a guide rail 53 that guides the moving body 52 a and a moving body 52 b that is guided by the guide rail 53. And the movable stand 21 is attached to those moving bodies 52a and 52b.

  In the traverse mechanism 18, when the traverse motor 50 is driven, the moving bodies 52 a and 52 b are guided by the guide rail 53, and the moving base 21 on which the first head 22 is placed moves in the direction of the rotation axis of the flyer 4. Is done. Thus, by driving the traverse motor 50, the flyer 4, the center formers 15 and 16, and the side plates 39 and 39 can be moved in the rotational axis direction of the flyer 4. This traverse mechanism 18 is used to move the wire 3 in the X-axis direction by the wire diameter of the wire 3 every time the wire 3 is wound around the magnetic pole 2 during winding of the wire 3 around the magnetic pole 2. It is done.

  On the other hand, the moving mechanism 17 that moves the center formers 15 and 16 and the side plates 39 and 39 separately from the traverse mechanism 18 moves the pair of center formers 15 and 16 in the vertical direction by moving the first rod 44 in the axial direction. And a second rod moving mechanism 56 that changes the inclination angle of the side plate 39 with respect to the rotation axis of the flyer 4 by moving the second rod 47 in the axial direction. The moving mechanism 17 including the first rod moving mechanism 55 and the second rod moving mechanism 56 is supported by a frame 57 provided behind the first head 22 that moves together with the moving base 21.

  A guide shaft 58 parallel to the rotation axis of the flyer 4 is installed on the frame 57 so as to be rotatable about its central axis. A pulley 59 a is attached to the rear end of the first spindle shaft 24 supported by the first head 22 at the rear end of the first head 22, and another pulley 59 b rotates with respect to the guide shaft 58. Mounted impossible. The pulley 59a and the pulley 59b are connected via a belt 59c, and are configured such that when the first spindle shaft 24 rotates, the guide shaft 58 also rotates.

  The first rod moving mechanism 55 has a second head 60 that is substantially parallel to the first head 22, and the guide shaft 58 is inserted through the second head 60. The second head 60 is supported by the guide shaft 58 and configured to be movable along the guide shaft 58. The second head 60 supports a cylindrical second spindle shaft 62 that is rotatable via a bearing 61, and a second central body that is not rotatable via a bearing 63 on the inner periphery of the second spindle shaft 62. 64 (the structure that makes the second central body 64 non-rotatable will be described later).

  A pulley 65 is attached to the rear end of the second spindle shaft 62. A pulley 67 is attached to a portion of the second head 60 where the guide shaft 58 is inserted so as to be rotatable with respect to the second head 60 and not movable in the axial direction. The pulley 67 is configured to be non-rotatable with respect to the guide shaft 58 and movable in the axial direction. The pulley 65 and the pulley 67 are connected via a belt 68. Thereby, when the guide shaft 58 rotates, the second spindle shaft 62 is also configured to rotate.

  The second spindle shaft 62 is provided such that the rotation axis is eccentric from the rotation axis of the first spindle shaft 24. When the first spindle shaft 24 rotates, the guide shaft 58 also rotates, so that the second spindle shaft 62 rotates in synchronization with the rotation of the first spindle shaft 24 by the rotation of the guide shaft 58. . The second spindle shaft 62 is formed with a through hole 62a through which the wire 3 is inserted. The second center body 64 is formed with a through hole 64a coaxially with the through hole 26a of the first center body 26, and the rear end of the first rod 44 is fixed to the through hole 64a so as not to move in the axial direction. Is done.

  A former vertical movement motor 71 is fixed to the movable table 21 covered by the frame 57, and a ball screw 72 parallel to the guide shaft 58 is connected to the output shaft of the former vertical movement motor 71. The ball screw 72 is screwed into the lower portion of the second head 60. Thus, when the former vertical movement motor 71 is driven, the second head 60 moves along the guide shaft 58 and moves the first rod 44 fixed to the second central body 64 in the axial direction. . In this way, by driving the former vertical movement motor 71, the first cam 45 at the tip of the first rod 44 can be moved forward or backward, and the pair of center formers 15 and 16 are moved in the vertical direction and separated from each other. Or configured to approach.

  On the other hand, the second rod moving mechanism 56 has a third head 75 substantially parallel to the second head 60. The guide shaft 58 is also inserted through the third head 75, and the third head 75 is supported by the guide shaft 58 and is movable along the guide shaft 58 in the same manner as the second head 60. The third head 75 supports a cylindrical third spindle shaft 77 that is rotatable via a bearing 76 and is non-rotatable via a bearing 78 on the inner periphery of the third spindle shaft 77. 79 is supported.

  A pulley 80 is attached to the rear end of the third spindle shaft 77. A pulley 82 is attached to a portion of the third head 75 where the guide shaft 58 is inserted so as to be rotatable with respect to the third head 75 and not movable in the axial direction. The pulley 82 is configured not to rotate with respect to the guide shaft 58 and to be movable in the axial direction. The pulley 80 and the pulley 82 are connected via a belt 83. Thereby, when the guide shaft 58 rotates, the third spindle shaft 77 is also configured to rotate.

  In the third spindle shaft 77, the rotation axis of the third spindle shaft 77 is coaxial with the rotation axis of the second spindle shaft 62 and is eccentric from the rotation axis of the flyer 4, that is, the rotation axis of the first spindle shaft 24. Thus, it is supported by the third head 75. On the other hand, the third spindle shaft 77 is configured to rotate in synchronization with the rotation of the first spindle shaft 24 and the second spindle shaft 62. The third spindle shaft 77 is formed with a through hole 77a through which the wire 3 is inserted. A rear end portion of the second rod 47 is connected to the third central body 79. In this way, the central axis of the first central body 26 and the central axes of the second central body 64 and the third central body 79 are connected eccentrically, so that the rotation of the central bodies 26, 64, 79 is restricted. The center bodies 26, 64, and 79 are configured to be prevented from rotating.

  A plate angle changing motor 85 is fixed to the moving table 21 covered with the frame 57, and a ball screw 86 parallel to the guide shaft 58 is connected to the output shaft of the plate angle changing motor 85. Screwed into the lower part of the head 75. Thus, when the plate angle changing motor 85 is driven, the third head 75 is moved along the guide shaft 58, and the second rod 47 connected to the third central body 79 is moved in the axial direction. . Thus, by driving the plate angle changing motor 85, the side plate support member 37 fixed to the tip of the second rod 47 can be moved backward or forward, whereby the flyer of the pair of side plates 39, 39 is obtained. The angle with respect to the rotation axis 4 (FIG. 3) can be changed. Here, reference numeral 87 in FIG. 1 denotes a pivot member 87 that is provided on the movable table 21 and pivotally supports the rear end portion of the ball screw 72 and the front end portion of the ball screw 86 in abutting state.

  Further, in the vicinity of the index mechanism 7, there is used a work pressing mechanism 88 that holds the multipolar armature 1 against the index base 11 by holding it against the index base 11. This work presser mechanism 88 is connected to an armature presser motor 90 fixed to an end of a support column 89 erected on the base 5 and an output shaft of the armature presser motor 90, and is a rotary shaft of the multipole armature 1. A ball screw 91 extending in the direction, a moving body 92 to which the ball screw 91 is screwed, and a guide rail 93 arranged to extend in the vertical direction on the support 89 and guide the moving body 92 are provided. A rotatable rod 95 is provided on the side surface of the moving body 92 via a bearing 94. The rod 95 is disposed coaxially with the rotation axis of the multipole armature 1, and an armature pressing member 96 that contacts the annular portion 1 a of the multipole armature 1 is connected to the lower end of the rod 95.

  When the armature presser motor 90 is driven, the moving body 92 is guided by the guide rail 93, and the armature presser member 96 moves in the direction of the rotation axis of the multipolar armature 1. In this way, by driving the armature presser motor 90, the armature presser member 96 comes into contact with the upper surface of the annular portion 1a of the multipole armature 1 placed on the index base 11, and the multipole armature 1 is moved. Press against the index table 11. As a result, the multipole armature 1 is configured to be held between the index base 11 and the armature pressing member 96. Since the rod 95 connected to the armature presser member 96 is supported via a bearing 94, the armature presser member 96 is multipolar during the rotation of the multipole armature 1 driven by the armature presser motor 90. It will rotate depending on the armature 1.

  Around the multi-pole armature 1, there are magnetic poles on both sides of the magnetic pole 2 to be wound in order to prevent the wire 3 fed from the flyer 4 from being caught by the magnetic poles on both sides of the magnetic pole 2 to be wound. A pair of side formers 97 that respectively cover the flange portions 2a are disposed (see FIGS. 1 and 3). The side former 97 is formed in a curved surface shape that tapers toward the tip, is supported by a support column 98 standing on the base 5, and is configured to be movable by a mechanism (not shown).

  In addition, the winding device 100 includes an armature moving mechanism 99 for making the vertical position (height) of the multipole armature 1 coincide with the rotation axis of the flyer 4. This armature moving mechanism 99 is connected to the support 101 arranged on the base 5, the armature moving motor 102 arranged on the top surface of the support 101, and the output of the armature moving motor 102, and the multipole armature. A ball screw 103 extending in the direction of one rotation axis (vertical direction), a moving body 104 to which the ball screw 103 is screwed, and a guide rail that extends in the vertical direction to guide the moving body 104. 105.

  The moving body 104 is connected to an index motor mounting table 106 on which the index motor 9 is mounted. A guide rod 107 extending in the vertical direction is arranged on the opposite side of the ball screw 103 with the index motor mounting table 106 as the center, and a moving body 108 coupled to the index motor mounting table 106 slides on the guide rod 107. It is inserted freely. When the armature moving motor 102 is driven, the moving body 104 is guided by the guide rail 105 and the moving body 108 slides on the guide rod 107, and the index motor mounting table 106 moves in the vertical direction. Thereby, the multipole armature 1 supported by the index base 11 moves in the vertical direction. As described above, by driving the armature moving motor 102 in the armature moving mechanism 99, the vertical position (height) of the multipole armature 1 can be matched with the rotation axis of the flyer 4. Is done.

  Next, the operation of the winding apparatus 100 will be described. The operation of the winding apparatus 100 is automatically controlled by a controller (not shown) mounted on the winding apparatus 100.

  First, as a preparation before winding, the wire 3 supplied from a wire supply source (not shown) is passed through a tension device (not shown) from the rear portion of the frame 57 to the through hole of the third spindle shaft 77. 77a, the through hole 62a of the second spindle shaft 62, and the through hole 24b of the first spindle shaft 24 are sequentially passed. And it guide | induces to the nozzle 27 of a fryer front end via the some roller 4a provided in the fryer 4. As shown in FIG. Then, the wire 3 drawn out from the nozzle 27 is locked to a pin 1 d provided on the annular portion 1 a of the multipole armature 1.

  Next, the multipole armature 1 is placed on the index base 11 such that the shaft 11a is inserted into the through hole 1c. In this state, the multipole armature 1 and the winding mechanism 6 are aligned. That is, by driving the armature moving motor 102 of the armature moving mechanism 99, the vertical position (height) of the multipole armature 1 and the rotation axis of the flyer 4 are matched. That is, the winding center axis of the magnetic pole 2 to be wound and the rotation axis of the flyer 4 are adjusted to be the same height. After the adjustment, by driving the armature presser motor 90, the armature presser member 96 is lowered toward the multipolar armature 1 and pressed against the annular portion 1a. In this way, the multipolar armature 1 is supported between the index base 11 and the armature pressing member 96.

  Next, the multi-pole armature 1 is rotated by driving the index motor 9, and the magnetic pole 2 to be wound among the plurality of magnetic poles 2 is set at the winding position. Specifically, the magnetic pole 2 to be wound is aligned with the rotation axis direction of the flyer 4. Thus, the position facing the rotation axis 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

  Next, the second rod moving mechanism 56 moves the side plate support member 37 (FIG. 3) together with the second rod 47 separately from the center former support plate 33, and the front ends of the side plates 39, 39 are moved to the front ends of the center formers 15, 16. 39b and 39b are matched (FIG. 2). In this state, the traverse motor 50 of the traverse mechanism 18 is driven to advance the first head 22 together with the moving base 21. As a result, the center former support plate 33, the side plate support member 37, and the plate-like member 48 also move forward, and as shown in FIGS. 2 and 3, the presser member 49 provided on the plate-like member 48 via the column 49a is moved. The magnetic pole 2 is brought into contact with the outer end surface. Thereafter, the first head 22 is further advanced, and the pair of center formers 15 and 16 and the pair of side plates 39 and 39 are disposed at the base end portion of the magnetic pole 2 as shown in FIGS.

  Specifically, the gap through which the wire 3 can enter between the tapered portions 15a and 16a of the pair of center formers 15 and 16 and the tips 39b of the pair of side plates 39 and 39 and the annular portion 1a of the multipole armature 1. Arrange so that At this time, in the pair of center formers 15 and 16, the first cam 45 (FIG. 2) is not in contact with the pair of vertical movement plates 35a and 35b, and as shown in FIG. It arrange | positions so that the magnetic pole 2 may be clamped from the Z-axis direction which is a thickness direction by the taper details 15a and 16a.

  On the other hand, as shown in FIG. 9, the pair of side plates 39, 39 are inclined with respect to the rotation axis of the flyer 4 so that the distance from each other approaches the tip, so When the side plate support member 37 further moves forward against the biasing force of the spring 40a and approaches the magnetic pole 2 after coming into contact with the magnetic pole 2, the holding member 49 is moved on the extension member 38 side of the pair of side plates 39, 39. The angle of inclination of the pair of side plates 39, 39 with respect to the rotation axis of the flyer 4 is increased by the biasing force of the spring 40b. As a result, the pair of side plates 39 and 39 move forward while reducing the distance between the tips, and as a result, the pair of side plates 39 and 39 rotate the flyer 4 as indicated by solid arrows in FIG. It will move diagonally with respect to the axis. Then, even if the outer peripheral side flange 2a of the magnetic pole 2 is sandwiched by the urging force of the coil spring 40b, the pair of side plates 39, 39 enter the inner peripheral side of the magnetic pole 2 to be wound, The magnetic pole 2 is sandwiched from the Y-axis direction, which is the width direction, at the tips 39b, 39b. As a result, even if the winding is already formed in the adjacent magnetic pole 2, the end of the side plate 39 facing the inner peripheral side of the multipole armature 1 is tried to be wound without contacting the winding. It can be made to approach to the inner peripheral side of the magnetic pole 2 to be performed.

  On the other hand, in the pressing member 49, the biasing force of the spring 40 a makes contact with the outer end surface of the magnetic pole 2 to prevent the magnetic pole 2 from moving away from the rotation axis of the flyer 4. Further, the width H (FIG. 4) of the tapered portions 15a and 16a of the pair of center formers 15 and 16 is substantially equal to the width W (FIG. 6) of the magnetic pole 2 to be wound, and as shown in FIG. The side plates 39, 39 sandwich the tapered portions 15 a, 16 a together with the magnetic pole 2. Then, as shown in FIG. 9, the pair of side formers 97 are moved, and the pair of side formers 97 are disposed so as to cover the flanges 2a of the magnetic poles 2 on both sides of the magnetic pole 2 to be wound. The above is preparation before winding.

  Next, the winding started in the state described above will be described.

  As shown in FIG. 1, with the flyer 4 positioned vertically above the magnetic pole 2, the flyer rotation motor 29 is driven to rotate the flyer 4 together with the first spindle shaft 24, and the wire 3 fed from the flyer 4 is Wind around the magnetic pole 2. The rotation of the first spindle shaft 24 is transmitted to the second spindle shaft 62 and the third spindle shaft 77 via the guide shaft 58, and the second spindle shaft 62 and the third spindle shaft 77 are also synchronized with the rotation of the flyer 4. Will rotate. Thereby, the wire rod 3 supplied from the wire rod supply source can be guided to the nozzle 27 without twisting.

  In the process in which the flyer 4 rotates 180 ° from vertically above to vertically below the magnetic pole 2, the wire 3 fed from the flyer 4 comes into contact with the side former 97 and is guided along the inclined surface, and then the center former. 15 and the side plate 39 are brought into contact with the magnetic pole 2 by sliding down the curved surface and guided to the magnetic pole 2 from the tip thereof. In the process in which the flyer 4 is rotated 180 ° from the vertically lower side to the vertically upper side of the magnetic pole 2, the wire 3 fed out from the flyer 4 comes into contact with the side former 97 and is guided along the inclined surface. Abutting against the center former 16 and the side plate 39, sliding down the curved surface thereof, being guided to the magnetic pole 2 from the tip thereof, and wound around the magnetic pole 2. Thus, as the flyer 4 makes one rotation, the wire 3 is 1 to 2 turns.

  When winding the wire 3 on the last surface (for example, the upper surface) of the four surfaces of the magnetic pole 2 in one winding around the magnetic pole 2, the flyer 4 and the center former 15 are driven by driving the traverse motor 50. , 16 and the pair of side plates 39, 39 are moved away from the multipole armature 1 by the wire diameter of the wire 3 in the winding direction (the radial direction of the magnetic pole 2 and the rotational axis of the flyer 4). In this way, the magnetic pole 2 is wound on the magnetic pole 2 by feeding the wire 3 for the diameter of the wire 3 on one predetermined surface (for example, the upper surface) of the four surfaces of the magnetic pole 2 with one rotation of the flyer 4. The wire 3 is wound in an aligned manner.

  During this aligned winding, the tapered portions 15a and 16a of the pair of center formers 15 and 16 hold the magnetic pole 2 with a slight gap from the Z-axis direction, and the pair of side plates 39 and 39 hold the magnetic pole 2 in the Y-axis direction. Therefore, the periphery of the magnetic pole 2 on which the winding is formed is surrounded by these, forming a so-called box structure. For this reason, the wire 3 is slid on the outer surfaces of the pair of center formers 15 and 16 and the pair of side plates 39 and 39 constituting the box structure and guided to the magnetic pole 2 so that the magnetic pole 3 is not damaged. It is possible to wind the wire 3 at a desired position 2 and align and wind the wire 3 around the magnetic pole 2.

  The arcuate portions 39c of the pair of side plates 39, 39 are formed so as to sandwich the tapered portions 15a, 16a of the pair of center formers 15, 16 from the Y-axis direction, and the pair of side plates 39, 39 Since the cover portions 15b and 16b that cover the side edges of the arc-shaped portion 39c in the axial direction of the multipole armature 1 are formed on the center formers 15 and 16, respectively, the side edges of the side plates 39 and the center formers 15 and 16 There is no gap at the border. For this reason, the wire rod 3 is prevented from entering between the side edge of the side plate 39 and the center formers 15 and 16. Therefore, the wire 3 that slides on the guide surfaces on the surfaces of the center formers 15 and 16 and the side plate 39 smoothly moves to a predetermined position of the magnetic pole 2.

  When such aligned winding is repeated, the pair of center formers 15 and 16 move in the X-axis direction, which is the rotational axis direction of the flyer 4, and as shown in FIG. 14, before the first layer winding is completed. Further, the tapered portions 15a and 16a come into contact with the flange portion 2a. Further, in order to continue the alignment winding of the first layer, as shown in FIG. 15, immediately before the tapered portions 15a, 16a of the pair of center formers 15, 16 come into contact with the flange portion 2a, as shown in FIG. Move 16 to increase the distance between each other.

  For the movement of the pair of center formers 15 and 16, the former vertical movement motor 71 shown in FIG. 1 is driven to advance the first cam 45 so as to contact the rollers 35c of the pair of vertical movement plates 35a and 35b. As a result, the pair of center formers 15 and 16 move away from each other in the vertical direction (the rotation axis direction of the multipole armature 1). The amount of movement in the Z-axis direction of each of the pair of center formers 15 and 16 is adjusted by the amount of advancement of the first cam 45, and the pair of center formers 15 and 16 has a slight gap between the flange portions 2a. It is set so as to be sandwiched from the Z-axis direction that is the axial direction of the child 1. In this manner, the aligned winding of the first layer can be continued by moving the pair of center formers 15 and 16 in the Z-axis direction. As shown in FIG. 15, the winding of the first layer is completed when the wire 3 comes into contact with the flange 2 a of the magnetic pole 2.

  At the time of winding of the first layer, the pair of side plates 39, 39 together with the pair of center formers 15, 16 with their tips 39b, 39b aligned with the tips of the pair of center formers 15, 16 It moves in the X-axis direction over the entire winding width of the magnetic pole 2. At this time, the pressing member 49 remains in contact with the outer end surface of the magnetic pole 2 by the urging force of the spring 40a and remains there. For this reason, the pressing member 49 can prevent the magnetic pole 2 from being displaced from the rotational axis of the flyer 4 when the first layer is wound. The pair of side plates 39, 39 sandwiching the pressing member 49 by the urging force of the spring 40b is pivotally supported by the side plate support member 37 via the extension member 38. When moving away, the tip distance is expanded. Then, the inclination angle of the pair of side plates 39, 39 with respect to the rotation axis of the flyer 4 also decreases, and the pair of side plates 39, 39 has a rotation axis of the flyer 4 as shown by solid arrows in FIG. Will move diagonally. Then, as shown in FIG. 10, the enlarged tips 39b, 39b of the pair of side plates 39, 39 sandwich the flange 2a, and the wire 3 guided from the tip 39b contacts the flange 2a of the magnetic pole 2. Thus, the winding of the first layer is completed.

  Subsequently, although 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 rotating, the traverse motor 50 is rotated in the direction opposite to the winding of the first layer, and the flyer 4, the center former 15, 16, and the pair of side plates 39, 39 are moved in a direction approaching the multipolar armature 1. .

  At the start of the second layer winding, the pair of center formers 15 and 16 move in the direction approaching the multipole armature 1 from the state shown in FIG. Then, when the tip details 15a and 16a move to a position shifted from the flange portion 2a, the pair of center formers 15 and 16 are narrowed to each other, and the first layer winding wound around the magnetic pole 2 is used. Are sandwiched between the tapered portions 15a and 16a 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. And as shown in FIG. 16, winding of the 2nd layer is performed until the wire 3 contact | abuts to the annular part 1a.

  At the time of this second layer winding, the pair of side plates 39, 39 together with the pair of center formers 15, 16 with their tips 39b, 39b aligned with the tips of the pair of center formers 15, 16 It moves in a direction approaching the multipole armature 1. At this time, the pressing member 49 abuts against the outer end surface of the magnetic pole 2 by the urging force of the spring 40 a to prevent the magnetic pole 2 from being displaced from the rotational axis of the flyer 4. The pair of side plates 39, 39 sandwiching the pressing member 49 by the urging force of the spring 40 b increases the inclination angle with respect to the rotation axis of the flyer 4 when moving from the outer peripheral side to the inner peripheral side of the multipole armature 1. The space | interval in the front-end | tip 39b and 39b is decreased. In this way, the pair of side plates 39, 39 moves obliquely with respect to the rotation axis of the flyer 4 as indicated by solid line arrows in FIG. 11. Then, the tips 39b and 39b whose distance decreases are in contact with the first layer winding.

  However, since the pair of side plates 39 and 39 can change the interval between the tips 39b and 39b facing the inner peripheral side of the multipolar armature by changing the inclination angle, It advances further in the state where 39b is in contact. That is, after the tip 39b comes into contact with the first layer winding, the pair of side plates 39, 39 has the first tip 39b, 39b in a state where the distance between the tips 39b, 39b is wider than that during the first layer winding. The wire 3 is guided while moving toward the inner peripheral side of the magnetic pole 2 while sandwiching the winding of the layer. Therefore, in the winding machine and winding method of the present invention, not only the first layer but also the second and subsequent layers are wound, the tips 39b and 39b of the side plates 39 and 39 are connected to the inner periphery of the magnetic pole 2. The side plate 39, 39 can be used to guide the wire 3 to the magnetic pole 2 and stable alignment winding is possible.

  In this case, the pair of side plates 39, 39 decreases the tip interval 39 b, 39 b while increasing the inclination angle with respect to the rotation axis of the flyer 4 when moving from the outer peripheral side to the inner peripheral side of the multipole armature 1. That is, as shown by a one-dot chain line in FIG. 18, in a state where the pair of side plates 39 and 39 are on the outer peripheral side and the holding member 49 is sandwiched between the tips 39b and 39b, the inclination angle of the flyer 4 with respect to the rotation axis is is decreasing. However, when the pair of side plates 39, 39 moves from the outer peripheral side to the inner peripheral side of the multipole armature 1, after passing through the intermediate state shown by the two-dot chain line by the biasing force of the spring 40b (FIG. 6), The pair of side plates 39, 39 is in a state indicated by a solid line that clamps the presser member 49 on the extension member 38 side. Then, the space | interval in the front-end | tips 39b and 39b of a pair of side plates 39 and 39 reduces, a pair of side plates 39 and 39 rotate centering on the pivot pin 38b (FIG. 6), and the inclination angle with respect to the rotating shaft of the flyer 4 (In FIG. 18, the angle with respect to the rotational axis of the flyer 4 gradually increases from α1 which is relatively small and becomes α2 through α1.5).

  As described above, when the tip interval 39b, 39b is decreased while the inclination angle with respect to the rotation axis of the flyer 4 is increased when moving from the outer peripheral side to the inner peripheral side of the multipole armature 1, it is indicated by a broken line arrow in FIG. As described above, the tips 39b, 39b of the pair of side plates 39, 39 facing the inner peripheral side of the multi-pole armature 1 draw an arc shape and narrow the distance between each other. Then, as compared with the case shown in FIG. 23 in which the side plates 202 and 202 are linearly moved without changing the inclination angle, the tip 39b of the side plate 39 is not brought into contact with the first layer winding. It is possible to increase the distance that enters the inner peripheral side of the magnetic pole 2. For this reason, the range of the winding of the 1st layer which the tip 39b of side plate 39 contacts and moves can be reduced. Then, as shown in FIG. 11, the tips 39b, 39b of the pair of side plates 39, 39 sandwich the winding of the first layer, and the wire 3 guided from the tip 39b abuts on the annular portion 1a. The winding of the second layer is completed.

  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. 12 and 17 show a state where the third layer winding is completed and all the windings scheduled for the magnetic pole 2 are completed. However, a winding of the fourth layer or higher may be further performed.

  As described above, the wire 3 is wound in multiple layers on the magnetic pole 2, and when the winding on one magnetic pole 2 is completed, the multi-pole armature 1 is rotated by driving the index motor 9, and the one The magnetic pole 2 and another magnetic pole 2 are arranged at the winding position, and a new winding is started.

  FIG. 21 shows a case where four layers of windings are made. As shown in FIG. 21, since the magnetic pole 2 is provided radially in the multipole armature 1, the slot 1b that is a gap between the magnetic pole 2 and the magnetic pole 2 is narrowed on the inner peripheral side. For this reason, when the winding of the first layer or higher is formed, the gap F between the wire 3 wound around the magnetic pole 2 and the winding 110 formed on the adjacent magnetic pole 2 is formed on the inner peripheral side of the wire 3. In some cases, the wire diameter is less than the diameter. Then, the winding to the gap F on the inner peripheral side becomes impossible. However, on the outer peripheral side, if the gap F between the wire 3 wound around the magnetic pole 2 and the winding 110 formed on the adjacent magnetic pole 2 exceeds the wire diameter of the wire 3, Further windings are possible.

  In this way, the gap F between the wire 3 wound around the magnetic pole 2 and the winding 110 formed on the adjacent magnetic pole 2 is less than the wire diameter of the wire 3 on the inner peripheral side, and the second and subsequent layers. At the time of winding, in part of the total winding width of the magnetic pole 2, specifically, the winding 110 formed on the magnetic pole 2 adjacent to the wire 3 wound around the magnetic pole 2 within the total winding width of the magnetic pole 2. In a part on the outer peripheral side of the armature 1 where the gap F exceeds the wire diameter of the wire rod 3, the pair of side plates 39, 39 are aligned with the tips 39 b, 39 b of the pair of center formers 15, 16. In this state, the wire 3 is guided to the magnetic pole 2 by both the pair of center formers 15 and 16 and the pair of side plates 39 and 39 in a part of the range by moving together with the pair of center formers 15 and 16. Is possible.

  Here, even when the gap between the wire 3 wound around the magnetic pole 2 and the winding 110 formed on the adjacent magnetic pole 2 exceeds the wire diameter of the wire 3, the side plate 39 enters the gap. When the distance G between the side plate 39 and the winding formed on the adjacent magnetic pole 2 is less than the wire diameter of the wire 3, the wire 3 does not slide on the surface of the side plate 39. 39 cannot be used to guide the wire 3. For this reason, a part of the total winding width is a range in which the distance G between the side plate 39 that has entered the slot 1 b and the winding 110 formed on the adjacent magnetic pole 2 exceeds the wire diameter of the wire 3. Become. However, if the concave grooves 39a and 39a into which the outer peripheral side flange 2a of the magnetic pole 2 can enter are formed in the opposing surfaces of the pair of side plates 39 and 39, respectively, extending in the rotation axis direction of the flyer 4, the magnetic pole 2 and the magnetic pole 2 During this time, the thickness t of the side plate 39 actually entering decreases, and the distance G between the side plate 39 and the winding 110 formed on the adjacent magnetic pole 2 increases. As a result, it is possible to expand a part of the entire winding width in which the wire 3 can be guided by the side plate 39. Further, even if such concave grooves 39a and 39a are formed, the strength of the side plate 39 can be secured by the thick portions 39e and 39e (FIG. 6) on both sides sandwiching the concave grooves 39a and 39a.

  On the other hand, the distance G between the side plate 39 and the winding 110 formed on the adjacent magnetic pole 2 is less than the wire diameter of the wire 3, but the wire wound around the magnetic pole 2 without the side plate 39 entering. If the gap F between the wire 3 and the winding 110 formed on the adjacent magnetic pole 2 exceeds the wire diameter of the wire 3, winding in that range is possible. As shown in FIGS. 19 and 20, the winding in this case is the outer peripheral side where the distance F (FIG. 21) between the side plate 39 and the winding 110 formed on the adjacent magnetic pole 2 exceeds the wire diameter of the wire 3. With the pair of side plates 39 and 39 remaining, only the pair of center formers 15 and 16 are moved in the direction of the rotation axis of the flyer 4, and the wire rod 3 is guided to the magnetic pole 2 by the pair of center formers 15 and 16. Thus, a winding is formed. As described above, the center formers 15 and 16 are moved by moving the center former support plate 33 together with the movable table 21 and the first head 22 by driving the traverse motor 50 of the traverse mechanism 18. However, in order to leave the pair of side plates 39, 39 on the outer peripheral side, the plate angle changing motor 85 shown in FIG. 1 is driven to move the side plate support member 37 together with the second rod 47 to move the center former support plate 33. Move in the opposite direction at the same speed as the speed. As a result, the pair of side plates 39, 39 are stationary with respect to the magnetic pole 2 and remain on the outer peripheral side.

  Thus, even if the gap F (FIG. 21) between the wire 3 wound around the magnetic pole 2 and the winding 110 formed on the adjacent magnetic pole 2 is reduced on the inner peripheral side, a part of the outer peripheral side In the range, the wire 3 can be guided to the magnetic pole 2 by both the pair of center formers 15 and 16 and the pair of side plates 39 and 39. Since the pair of center formers 15 and 16 can move independently of the pair of side plates 39 and 39 in the direction of the rotation axis of the flyer 4, the pair of side plates 39 and 39 remain on the outer peripheral side. Thus, by moving only the pair of center formers 15, 16 in the direction of the rotation axis of the flyer 4, winding beyond a part of the range is possible. Therefore, in the present invention, even the upper layer winding can be sufficiently aligned.

  In the above-described embodiment, the side plate urging means 40b and the plate-like member urging means 40a are exemplified by the coil spring, but the interval between the side plate support member 37 and the plate-like member 48 is increased. The plate-like member urging means and the side plate urging means are air as long as the pair of side plates 39, 39 are urged so that the pair of side plates 39, 39 hold the pressing member 49. An air cylinder or the like that generates an urging force by pressure may be used.
