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 wires adjacent to the magnetic pole are aligned with no gap, is effective. For this reason, in a flyer type winding machine, a pair of center formers that sandwich the magnetic pole to be wound from the axial direction of the multipole armature with respect to a multipole armature with a fixed position, and the pair of center formers There is known a mechanism including a moving mechanism that moves the pole armature so as to be separated from each other in the axial direction, and a side former that covers a magnetic pole adjacent to the magnetic pole to be wound (see, for example, Patent Document 1).

  That is, in this flyer-type winding machine, the center former sandwiches the magnetic pole to be wound of the multi-pole armature, is arranged so that there is no gap between the magnetic pole and the center former, and is fed from the flyer. The wire is slid on the guide surface of the center former and guided from the tip to the magnetic pole to be wound. At the same time, aligned winding is performed by moving the flyer that feeds the wire while rotating in the direction of the rotation axis. Here, when winding is performed when the tip of the center former is close to the magnetic pole, the tip of the center former comes into contact with the flange on the outermost peripheral portion of the multipolar armature. Then, the distance between the pair of center formers is widened by the moving mechanism so that the tips thereof are positioned outside the collar portion, and further winding is performed in this state. Then, when the wire comes into contact with the flange, the first layer winding is finished. Thereafter, the second layer is wound by the center former moving in the opposite direction to the first layer winding. The center former guides the wire and moves away from the collar, whereby the second layer is wound on the first layer coil. When the center former moves to the inner circumference side of the magnetic pole, the movement By reversing the direction, the third layer is wound, and if necessary, the multi-layer such as the fourth layer is also wound.

Japanese Patent Laid-Open No. 10-257724

  As described above, the center former of the winding machine is important in controlling where the wire is wound around the magnetic pole, and is a multi-pole armature having a relatively small number of magnetic poles such as 4-6. In some cases, it can be sufficiently aligned. However, in the case of a multi-pole armature with 12 or 18 magnetic poles or more, even if a center former is provided, alignment winding may be difficult for the magnetic poles to be wound. is there.

  That is, the wire guided to the magnetic pole by the center former sandwiching the magnetic pole from the axial direction of the multipole armature is pulled outward in the radial direction of the multipole armature by the side former. However, in the case of a multipole armature having 12 or 18 magnetic poles or more, the angle formed by one magnetic pole and the magnetic pole adjacent thereto becomes small, and the magnetic pole to be wound becomes multipolar. The level difference between the center former sandwiched from the axial direction of the armature and the side former covering the adjacent left and right magnetic poles is relatively large. For this reason, the angle formed by the wire extending from the flyer and guided to the magnetic pole by the center former and extending in the circumferential direction of the multi-pole armature, and the wire extending by the side former and extending outward in the radial direction of the multi-pole armature growing.

  On the other hand, in order to avoid the tip of the center former from coming into contact with the flange, there is a gap between the tip of the center former and the winding magnetic pole from the moment when the pair of center formers increases the mutual distance. Arise. Then, the wire rod pulled radially outward by the side former may enter the gap between the tip of the center former and the magnetic pole, and it may not be possible to wind the wire to a portion where the wire is originally intended to be wound. For this reason, the conventional flyer-type winding apparatus including the center former and the side former has a room for improvement because the wire winding may be disturbed in the process of winding the wire around the magnetic pole.

  An object of the present invention is to provide a winding apparatus and a winding method capable of stably aligning and winding wires around magnetic poles of a multipole armature having a relatively large number of magnetic poles.

  The present invention is arranged 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 move in the radial direction of the multipole armature as the flyer rotates and guide the wire fed from the flyer from the tip edge to the magnetic pole, and the pair of center formers in the axial direction of the multipole armature And a first moving mechanism for moving the blades so as to be separated from each other.

  The characteristic configuration is that the magnetic pole is sandwiched from the circumferential direction of the multi-pole armature and the tip edge is arranged to be flush with the tip edge of the pair of center formers, together with the pair of center formers as the flyer rotates. A pair of side plates that move in the radial direction of the multipole armature and a second moving mechanism that moves the pair of side plates so as to be separated from each other in the circumferential direction of the multipole armature are provided.

  And when the collar part which restrict | limits a winding range is formed in the protrusion end of a magnetic pole, it is preferable to each form the opening which a collar part can approach into a pair of side plate which clamps a magnetic pole, More preferably, the center former is formed with a cover that covers the side edges of the side plates sandwiched from the circumferential direction of the multipolar armature from the axial direction of the multipolar armature.

  The winding method of the present invention includes a flyer that rotates around a magnetic pole in a multipole armature, moves in the radial direction of the multipole armature, and winds a wire around the magnetic pole, and the multipole armature. And a pair of center formers that are arranged so as to be sandwiched from the axial direction of the wire and move in the radial direction of the multi-pole armature as the flyer moves and guide the wire fed from the flyer from the tip edge to the magnetic pole. This is a winding method in which a wire is wound around each magnetic pole of a multipole armature using a winding device.

  The characteristic point is that a pair of side plates that sandwich the magnetic poles from the circumferential direction of the multi-pole armature are arranged so that the leading edges are flush with the leading edges of the pair of center formers. Move the pair of side plates together with the pair of center formers in the radial direction of the multi-pole armature, and wind the wire fed from the flyer by both the pair of center formers and the pair of side plates guided by the magnetic poles and wound. is there.

  In the winding machine and winding method of the present invention, a pair of side plates are arranged so that the magnetic poles are sandwiched from the circumferential direction of the multipole armature and the leading edges are flush with the leading edges of the pair of center formers. Since the wire rod is provided, the wire rod pulled outward in the radial direction during winding is guided to the magnetic pole by the side plate. Since the leading edge of the side plate that guides the wire to the magnetic pole is flush with the leading edge of the center former, the wire can be guided by the side plate to the magnetic pole portion that the center former originally intends to guide. For this reason, in order to avoid the tip of the center former from coming into contact with the flange, even if a gap is formed between the pair of center formers and the magnetic poles, the wire rods enter the gap. There is nothing. Then, by moving the pair of side plates in the radial direction of the multipole armature together with the pair of center formers as the flyer rotates, the wires can be stably aligned and wound around the magnetic poles.

  Moreover, if the opening which a collar part can approach is formed in a pair of side plate which clamps a magnetic pole, respectively, the mutual space | interval of a pair of side plate will be narrowed by making a collar part approach into the opening. This makes it possible to achieve more stable aligned winding by guiding the wire to the magnetic pole while preventing the side plate from interfering with the magnetic pole adjacent to the magnetic pole performing winding.

  And if the cover part which covers the side edge of the side plate which clamps a magnetic pole from the circumferential direction of a multi-pole armature from the axial direction of a multi-pole armature is formed in a center former, the wire which slides the guide surface in the surface of a center former Can be prevented from entering between the side edge of the side plate and the center former.

  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.

Further, as shown in FIG. 7, the dimension N in the X-axis direction of the opening 39a is such that the front end edge 39b of the side plate can approach the annular portion 1a in a state where the flange portion 2a enters the opening 39a. As shown in FIG. 8, the tip edge 39b is formed to be able to reach the vicinity of the flange 2a away from the annular portion 1a in a state where the flange 2a enters the opening 39a.

  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 11 are formed.

The The trapezoidal second cam is disposed so that the inclined surfaces 48a on both sides of the trapezoidal second cam abut against the opposed inclined surfaces 38c of the pair of moving plates 38a, 38b by retreating together with the second rod 47.

  Since the inclined surfaces 38c of the pair of moving plates 38a and 38b are formed opposite to the inclined surface 48a of the second cam 48, the second cam 48 is inclined by retreating between the pair of moving plates 38a and 38b. When the surface 48a abuts on the inclined surface 38c, the pair of moving plates 38a and 38b are pushed and spread against the urging force of the springs 40a and 40b, and move in the horizontal direction. As described above, the pair of side plates 39 and 39 are moved away from each other by moving the second cam 48 backward, and the pair of moving plates 38a and 38b are moved by the springs 40a and 40b by moving the second cam 48 forward.

Is done. Thus, by driving the traverse motor 50, the flyer 4, the center formers 15, 16 and the pair of side plates 39, 39 can be moved in the rotational axis direction of the flyer 4. The traverse mechanism 18 is used to move the wire 3 in the X-axis direction by the outer 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. .

  On the other hand, the moving mechanism 17 that moves the pair of center formers 15 and 16 and the pair of side plates 39 and 39 apart from each other moves the first rod 44 in the axial direction to move the pair of center formers 15 and 16 in the vertical 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 horizontal movement 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 an output shaft of the plate horizontal movement motor 85. Screwed into the lower part of the head 75. Thus, when the plate horizontal movement motor 85 is driven, the third head 75 moves along the guide shaft 58, and the second rod 47 connected to the third central body 79 moves in the axial direction. . In this way, by driving the plate horizontal movement motor 85, the second cam 48 at the tip of the second rod 47 can be moved backward or forward, and the pair of side plates 39, 39 are moved in the horizontal direction to each other. It is configured to be able to be separated or approached. 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 the bearing 94, the armature presser member 96 is used as the multipole armature during rotation of the multipole armature 1 by driving the index motor 90. It depends on 1 and rotates.

  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 6). 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 traverse motor 50 of the traverse mechanism 18 is driven to advance the first head 22 together with the moving base 21, and the flyer 4, the pair of center formers 15 and 16, and the pair of side plates 39 and 39 are brought into the winding position. It arrange | positions at the base end part of the arrange | positioned magnetic pole 2. As shown in FIG. 6 and 7, between the tapered portions 15a, 16a of the pair of center formers 15, 16 and the tip edges 39b of the pair of side plates 39, 39 and the annular portion 1a of the multipole armature 1 It arrange | positions so that the clearance gap in which the wire 3 can approach will be opened. Further, in the pair of center formers 15 and 16, the first cam 45 is not in contact with the pair of vertical movement plates 35a and 35b, and as shown in FIG. The magnetic pole 2 is arranged so as to be sandwiched from the Z-axis direction which is the thickness direction.

  On the other hand, in the pair of side plates 39, 39, the second cam 48 is not in contact with the pair of horizontal movement plates 38a, 38b, and the distance between them is reduced by the urging force of the springs 40a, 40b. As shown in FIG. 6, the magnetic pole 2 is sandwiched from the Y-axis direction which is the width direction. Then, since the flange portion 2a of the magnetic pole 2 enters the opening 39a formed in the side plate 39, the side plate 39 on the tip side from the opening contacts the magnetic pole 2 or has a gap smaller than the diameter of the wire 3. It arrange | positions so that the magnetic pole 2 may be pinched | interposed. Here, the width H of the tapered portions 15a, 16a of the pair of center formers 15, 16 is substantially equal to the width W of the magnetic pole 2 to be wound, and the pair of side plates 39, 39 together with the magnetic pole 2 has the tapered portion 15a. 16a is also sandwiched. Then, as shown in FIG. 6, the pair of side formers 97 are moved, and the pair of side formers 97 are arranged so as to cover the flange portions 2a of the magnetic poles 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.

  With the flyer 4 positioned vertically above the magnetic pole 2, the flyer rotating 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 wound around the magnetic pole 2. To do. 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 outer diameter of the wire 3 in the winding direction (the radial direction of the magnetic pole 2). As described above, the magnetic pole 2 is wound by feeding the outer 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 alignment.

  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 where the winding is formed is surrounded by these so as to form 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 a wire rod at a desired position 2 and wind the wire 3 around the magnetic pole 2 in an aligned manner.

  When such aligned winding is repeated, the pair of side plates 39, 39 move in the X-axis direction, which is the radial direction of the multipole armature 1, and before the first layer winding is completed as shown in FIG. The flange 2a entering the opening 39a comes into contact with the lip of the opening 39a. When such aligned winding is repeated, the pair of center formers 15 and 16 also move in the X-axis direction, which is the radial direction of the multipole armature 1, and the first-layer winding is completed as shown in FIG. Before this, the tapered portions 15a and 16a come into contact with the flange portion 2a.

  In order to continue the aligned winding of the first layer, the pair of side plates 39 and 39 are moved to increase the distance from each other as shown in FIG. 10 immediately before the flange portion 2a comes into contact with the edge of the opening 39a. spread. In order to move the pair of side plates 39, 39, the plate horizontal movement motor 85 is driven to retract the second cam 48 together with the second rod 47, and the first side plates 39, 39 are moved to the inclined surfaces 38c, 38c of the pair of horizontal movement plates 38a, 38b. The inclined surface 48a of the two cams 48 is brought into contact. As a result, the pair of side plates 39, 39 move away from each other in the width direction of the magnetic pole 2 disposed at the winding position. The amount of movement of the pair of side plates 39, 39 in the Y-axis direction is adjusted by the amount of retraction of the second cam 48, and the pair of side plates 39, 39 has a slight gap around the flange portion 2a. It is set so as to be sandwiched from the Y-axis direction which is the circumferential direction.

  Further, in order to continue the aligned winding of the first layer, the pair of center formers 15, 16 just before the tapered portions 15 a, 16 a abut against the flange 2 a, as shown in FIG. 16 is moved 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 is driven to advance the first cam 45 and 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.

  Thus, the first layer of aligned winding can be continued by moving the pair of side plates 39, 39 in the Y-axis direction and moving the pair of center formers 15, 16 in the Z-axis direction. Then, as shown in FIGS. 12 and 13, the first layer winding is performed until the wire 3 comes into contact with the flange 2 a of the magnetic pole 2.

  Here, as shown in FIG. 7 and FIG. 9, the wire 3 guided to the magnetic pole 2 by the center formers 15 and 16 sandwiching the magnetic pole 2 from the axial direction of the multipole armature 1, The magnetic pole 2 is wound so as to extend in the Y-axis or Z-axis direction. However, in the multipole armature 1 in this embodiment in which the number of magnetic poles is 18 (only seven of them are shown in FIG. 6), one magnetic pole 2 to be wound and the magnetic pole 2 adjacent thereto are wound. The center formers 15 and 16 that sandwich the winding magnetic pole 2 from the Z-axis direction that is the axial direction of the multipole armature 1, and the side formers 97 that cover the adjacent left and right magnetic poles 2 and 2 are reduced. The step with 97 is relatively large. For this reason, as shown in FIGS. 6 and 8, the wire 3 that is drawn out from the flyer 4 and guided to the magnetic pole 2 by the center formers 15 and 16 and extends in the circumferential direction of the multipole armature 1, and the side formers 97 and 97. The angle formed by the wire 3 that is pulled by the wire 3 and extends outward in the radial direction of the multipole armature 1 increases.

  However, since the winding machine 100 of the present invention includes the pair of side plates 39 and 39 that sandwich the magnetic pole 2 from the circumferential direction of the multipolar armature 1, the wire 3 pulled outward in the radial direction by the side former 39. The side plate 39 guides to the magnetic pole 2. Since the front edge 39a of the side plate 39 that guides the wire 3 to the magnetic pole 2 is flush with the front edges of the center formers 15 and 16, the wire 2 is placed on the portion of the magnetic pole 2 that the center formers 15 and 16 originally intend to guide. 3 can be reliably guided by the side plate 39. For this reason, even if a gap is generated between the tip of the center former 15 and 16 and the magnetic pole 2 by moving the pair of center formers 15 and 16 in the Z-axis direction, the wire material 3 is placed in the gap. There is no such thing as getting in. That is, even if the distance between each other is increased, the pair of center formers 15 and 16 and the pair of side plates 39 and 39 form a so-called box structure surrounding the magnetic pole 2, so that the wire rod 3 fed out from the flyer 4 is used. Can be guided to a desired position of the magnetic pole 2 and the wire 3 can be aligned and wound.

  The arcuate portions 39c of the pair of side plates 39, 39 are formed so as to sandwich the respective tapered details 15a, 16b 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 boundary portion, and it is possible to effectively prevent the wire 3 from entering between the side edge of the side plate 39 and the center formers 15 and 16. Therefore, the wire that slides on the guide surfaces on the surfaces of the center formers 15 and 16 smoothly moves to the surface of the side plate 39, and the wire that slides on the guide surfaces on the surfaces of the side plates 39 smoothly on the surfaces of the center formers 15 and 16. Will be moved to. Therefore, even when the number of magnetic poles 2 is relatively large as in the multipole armature 1 in this embodiment, the wire 3 can be stably aligned and wound around the magnetic poles 2.

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

  When this second layer winding is started, the pair of side plates 39, 39 move in a direction approaching the multi-pole armature 1 in the X-axis direction, and as shown in FIG. The flange 2a faces the surface 39a, and the flange 2a can enter the opening 39a. When the second layer winding is started, the pair of center formers 15 and 16 are also moved in the direction approaching the multipole armature 1, and as shown in FIG. It will move to a position deviated from.

  Then, in the pair of side plates 39, 39, the plate horizontal movement motor 85 is driven to advance the second cam 48 together with the second rod 47, thereby narrowing the distance between the pair of side plates 39, 39. . Then, as shown in FIG. 16, the first layer winding wound around the magnetic pole 2 is sandwiched between the pair of side plates 39, 39 with a slight gap from the Y-axis direction. Thus, the side plates 39 and 39 can be prevented from interfering with the magnetic pole 2 adjacent to the magnetic pole 2 performing the winding, and the leading edge 39b for guiding the wire 3 can be brought close to the magnetic pole 2. Further, even in the pair of center formers 15 and 16, the distance between each other is narrowed, and as shown in FIG. 17, the windings of the first layer wound around the magnetic pole 2 have their tapered portions 15a and 16a. Hold it 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. The second winding is performed until the wire 3 comes into contact with the annular portion 1a.

  Subsequently, although the third layer winding is performed, this third layer winding is the same as the first layer winding procedure, and when performing the fourth layer winding, the second layer winding is performed. Since this is the same as the winding procedure, repeated description is omitted. 18 and 19 show a state in which the winding of the fourth layer is completed and all the windings scheduled for the magnetic pole 2 are completed. Here, since the slot 1b between the adjacent magnetic poles 2 of the multipole armature 1 expands in the outer diameter direction, the wire 3 has a substantially trapezoidal shape on the magnetic pole 2 as shown in FIGS. Winded. This is because the wire 3 is wound between the annular portion 1a and the flange portion 2a of the magnetic pole 2 in the first few layers after the start of winding, but the wire 3 becomes annular portion 1a as the number of layers increases. This is because the winding position of the wire 3 approaches the flange portion 2a from the annular portion 1a as the number of layers cannot be increased.

  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.
