[0001]
BACKGROUND OF THE INVENTION
The present invention mainly relates to a winding machine for winding a coil forming wire around a multipole armature.
[0002]
[Prior art]
Conventionally, a winding machine is widely used to wind a wire for forming a coil around a pole of a multipole armature. In order to improve the performance with a limited size of the armature such as a motor, the winding machine is required how many windings can be made in the limited winding space of the multi-pole armature. The For this purpose, so-called aligned winding, in which the wires adjacent to the pole are aligned and wound without any gap, is effective.
[0003]
For this purpose, as shown in FIG. 12, in the flyer-type winding machine 50, the pole on which the former guide 7 is wound is sandwiched from above and below the multi-pole armature 28 whose position is fixed. As shown in FIG. 13, the wire former W drawn from the winding nozzle is poled by rotating a flyer 5 (see FIG. 12) that covers the left and right poles 29 adjacent to each other, not shown, and holds the winding nozzle. 29.
[0004]
The reason why the pole 29 wound by the former guide 7 is sandwiched from above and below is that when the interval between the adjacent poles 29 is narrow, the conventional inner block 29a (not shown) having a concave center is up to the pole inner peripheral side 29a. It is because it cannot enter. By providing the former guide 7 in the vertical direction, the former guide 7 does not interfere with the adjacent pole 29 on the pole inner peripheral side 29a.
[0005]
[Problems to be solved by the invention]
However, even in the former guide 7, there is a portion where alignment winding is difficult with respect to the pole 29 to be wound. First, the former guide 7 sandwiches the pole 29 to be wound of the multipole armature 28, and is disposed so that there is no gap between the pole 29 and the former guide 7 (FIG. 14A). The wire W drawn from the flyer 5 passes (slids) through the guide surface 7a of the former guide 7 and is wound around the pole 29 to be wound, and the entire winding head 4 is the axis of the spindle shaft 3 which is the rotation axis of the flyer 5. Aligned winding is done by moving in the direction. As the winding is performed, the opening / closing action surface 7b of the former guide comes into contact with the flange 30 at the outermost peripheral portion of the multipole armature 28 (FIG. 14B). Then, the former guide 7 opens around the axis 10 of the former base 9. The former guide 7 is wound while being opened (FIG. 14C), and when the wire W is in contact with the flange 30, the first layer winding is finished (FIG. 14D). After that, the second layer is wound by moving the former guide 7 in the direction opposite to the winding of the first layer (FIG. 15A). As the opening / closing action surface 7b of the former guide 7 moves away (advances) from the flange 30, the former guide 7 is closed and the second layer is wound while pressing on the first layer coil (FIG. 15 (b)). ), FIG. 15 (c)). When the former guide 7 moves to the pole inner peripheral side 29a, the former guide 7 moves in the opposite direction and the third layer is wound, and the fourth layer and the like are wound as necessary.
[0006]
Here, as shown in FIGS. 14 (c) and 14 (d), the opening / closing action surface 7 b of the former guide hits the flange 30, so that the former guide 7 and the multipolar armature 28 are started from the moment when the former guide 7 is opened. Since a gap larger than the wire diameter of the wire W is generated between the wires W, the wire W jumps into the gap, and it becomes impossible to control the portion where the wire W is originally intended to be wound. That is, when the former guide 7 is open, it is not guided by the guide surface 7a of the former guide 7, so that a dead space D in which the winding of the wire W cannot be controlled occurs on the pole outer peripheral side 29b, making it difficult to achieve ideal aligned winding. It becomes.
[0007]
An object of the present invention is to provide a winding machine that enables aligned winding even on the pole outer periphery side.
[0008]
[Means, functions and effects for solving the problems]
In order to solve the above problems, the winding machine of the present invention Configuration Is
Of the multi-pole armature to be wound Around the pole Around the axis of rotation While turning For coil formation A flyer that feeds the wire, Said The pole From top to bottom The above While moving in the axial direction of the rotating shaft, The wire drawn out from the flyer Said With a pair of former guides to guide the poles Roll In the wire machine,
Said Arranged in the vicinity of the pole and the former guide, The axis of the rotating shaft on the outer circumference side of at least the entire winding width of the pole A side guide that can move in the direction
That Polar outer side The pair of former guides move in the axial direction of the rotating shaft and open apart from each other in the vertical direction, thereby entering a gap formed between the former guide and the pole. Wire The above Side guide replaces former guide Guide to the pole It is characterized by that.
[0009]
The side guide is attached to the former base to which the former guide is attached via a slide mechanism in the direction of the flyer's rotation axis, and is configured to move within the movement range in the direction of the flyer's rotation axis. And
That is, the former guide and the side guide are normally movable relative to each other, but can move integrally with each other in a specific region. More specifically, in the entire winding width (width from the inner circumference end to the outer circumference end) including the base end side (pole inner circumference side) of the pole to be wound and the tip end side (pole outer circumference side) of the pole. In the process of winding from the pole outer circumference side to the pole inner circumference side, the side guide is held fixed at the pole outer circumference side, while only the former guide is advanced from the pole outer circumference side to the pole inner circumference side (side guide). Winding progresses while guiding the wire. Even in the process in which the former guide is retracted from the pole inner circumference side to the pole outer circumference side, the former guide guides the wire rod, winding is performed, and the former guide approaches the side guide. Therefore, when the former guide enters the predetermined area on the extreme outer circumference side, the former guide guide After that, the former guide and the side guide are both retreated (for example, synchronized with each other or integrally retreated), and the region on the extreme outer peripheral side is wound. At this time, the side guide replaces the former guide even if the former guide opens and closes with respect to the end of the pole and a gap is generated between the former guide and the winding of the pole, making it impossible to control the wire rod. The wire is guided in the end region on the pole outer periphery side. Former guides are usually opened once when the tip of a pole (generally with a flange) is crossed over from the outside to the inside. As a form that does not interfere with the end portion), a predetermined amount of light enters the pole, and movement of a distance necessary for the wire guide in the winding on the pole outer peripheral side is secured with respect to the pole outer peripheral end portion. In addition, it is possible to adopt a structure in which the side guide and the former guide move together within the allowable movement range of the side guide.
[0010]
In such a configuration, the side guide guides the winding after the former guide is opened. Therefore, even if a gap larger than the wire diameter of the winding occurs between the former guide and the multipole armature, it also occurs. After that, the wire can be controlled to the part that is originally intended to be wound.
[0011]
The side guide is attached to the former base to which the former guide is attached via a slide mechanism in the direction of the rotary shaft of the flyer, and is driven via a transmission rod penetrating the rotary shaft of the flyer. It is characterized by comprising an independent moving means different from that of the flyer so that it can move in the direction of the rotation axis of the flyer.
[0012]
In this case, since the positional relationship between the guide surface of the side guide and the guide surface of the former guide is not fixed to the dimensions of each component, it can be made the same surface or be slightly displaced. It is also possible to change the positional relationship between the first layer and the second layer, or to change the positional relationship at each pole of the multipole armature. That is, any adjustment that meets the conditions of the positional relationship between the former guide and the side guide can be easily performed, so that the wire can be guided to a more desirable position.
[0013]
In addition, the opening / closing mechanism of the former guide is driven through an opening / closing shaft penetrating the center of the rotary shaft of the flyer, and is provided with an opening / closing drive section that can be freely opened and closed and finely adjusted in opening / closing amount.
[0014]
In this case, the former guide was opened and closed when the opening / closing action surface of the former guide hits the hook, but can be arbitrarily opened and closed by the opening / closing drive unit, so that the hook does not hit the opening / closing action surface of the former guide. As a result, the hook is not bent by the opening / closing action surface of the former guide, so that the hook is not bent and the multi-pole armature is not defective. In addition, since the opening / closing amount of the former guide can be arbitrarily set, when winding the second layer or more, it is possible to wind with leaving a gap smaller than the diameter of the wire without contacting the already wound wire. Therefore, winding can be performed without damaging the insulating coating of the wire.
[0015]
Furthermore, the former guide is provided with a guide portion for opening and closing in a direction crossing the axial direction of the rotating shaft on the side opposite to the side for guiding the wire.
Corresponding to the guide portion, a rail portion for guiding the guide portion is provided on the former base.
[0016]
When the former guide is opened and closed in a direction intersecting with the axis direction of the rotation axis, and further in a direction perpendicular to the axis direction, the thickness of the contact portion of the former guide contacting the pole can be made thinner. This makes it possible for the former guide to guide the wire to the outer periphery of the pole, thereby increasing the winding distance for winding the wire around the pole by the former guide and conversely winding the wire around the pole by the side guide. The line distance will be reduced. For this reason, it is not necessary to insert the side guides deep inside the poles, the side guides do not contact the adjacent poles, and it is possible to wind even a multi-pole armature in which the distance between the adjacent poles is narrow. Further, the former guide can always be wound in the same form regardless of the thickness of the pole. That is, since the former guide does not tilt and the winding state does not change, the variation in products is greatly reduced.
[0017]
Next, the transmission shaft as the transmission rod is provided penetrating in the axial direction with respect to the rotation shaft,
Further, the open / close shaft is provided so as to penetrate the transmission shaft in the axial direction thereof.
[0018]
Thereby, the rotating shaft, the transmission shaft, and the opening / closing shaft are arranged concentrically, that is, provided as a triple structure. As a result, the diameter of the rotating shaft provided on the outermost side can be reduced, the output of the rotating shaft rotating motor can be reduced, and the winding machine itself can be reduced in size.
[0019]

The winding machine 100 is mainly composed of a base 1, a movable body 2, a spindle shaft 3, a winding head 4, a flyer 5, and a multipole armature holding means 6. The winding head 4 is mainly composed of a former guide 7, a side guide 8 and a former base 9. The former guide 7 is supported so as to be openable and closable around the axis 10 of the former base 9. An elastic member (urging means) such as a spring 11 is provided between the former guide 7 and the former base 9 to urge the former guide 7 in the closing direction. However, in this example, it has enough force to close.
[0020]

An elastic member (biasing means) such as a spring 13 is provided between the side guide 8 and the former base 9 and is pressed against the flange 30 of the multipole armature by the stopper portion 8a of the side guide 8 at the start of winding. The stopper member 12 attached to the side guide 8 is arranged coaxially with the spring 13, and the winding head 4 is wound on the pole outer peripheral side 29b (see FIGS. 4 and 5) of the multipole armature during winding. The former guide 7 is provided to move together.
[0021]
The flyer 5 includes a wire feeding reel 5a for feeding the wire W. The flyer 5 is fixed to the spindle shaft 3. The spindle shaft 3 is rotatably supported by the movable body 2 via a bearing 40. The spindle shaft 3 is rotated via a pulley 15 and a timing belt 16 by a spindle shaft rotating motor 14. The winding head 4 is disposed coaxially with the spindle shaft 3 and is supported by a bearing 17 in a non-rotating state. A plurality of (for example, three) planetary gear shafts 18a are rotatably mounted on the flyer 5 via bearings 42, and the planetary gears 18 and 18 are respectively fixed to the flyer 5 with screws or the like. On the other hand, fixed gears 19, 19 are fixed to the former base 9 with the movable body 2 by screws or the like, and the planetary gears 18 revolve while engaging with the fixed gear 19, whereby the spindle shaft 3 rotates. However, the winding head 4 is held unrotatable only by the planetary gear 18 rotating, and the lateral load applied to the winding head 4 via the wire W is received.
[0022]
An opening / closing shaft 20 for opening / closing the former guide 7 is provided inside the spindle shaft 3. The opening / closing shaft 20 is provided so as to be movable in the axial direction of the spindle shaft 3 (strictly, in a direction parallel to the axial direction) by a pneumatic cylinder 21 fixed to the movable body 2. An arm 38 is fixed over both of the pneumatic cylinder shaft 21a and the opening / closing shaft fixing member 37 so as to connect them. The opening / closing shaft fixing member 37 is attached to the opening / closing shaft 20 via a bearing 43, so that it can move in the axial direction of the spindle shaft 3. As the opening / closing shaft 20 advances, the taper portion 20a at the end of the opening / closing shaft 20 enters or leaves between the cam follower portions 7c, 7c (a pair) formed at the rear end of the former guide 7 as the opening / closing shaft 20 advances. As a result, the former guide 7 can be opened and closed around the axis 10 of the former base 9. In the former guide 7, a pair of movable members are rotatably connected to each other by the shaft 10 at each intermediate portion, and the cam follower portions 7c and 7c are formed in a spherical shape at the end opposite to the pole 29 with respect to the shaft 10. It is formed to have other convex curved surfaces.
[0023]
The movable body 2 holds the winding head 4, the flyer 5, and the spindle shaft 3, and is provided on the base 1 so as to be movable in the axial direction of the spindle shaft 3. In the movable body 2, a ball screw shaft 23a fixed to the output shaft 22a of the winding head moving motor 22 fixed to the base 1 rotates forward and backward, and on a rail (not shown) via a nut portion 23 of the ball screw. It can be moved.
[0024]
The multipole armature holding means 6 includes an indexing rotary shaft 24 for holding the multipole armature and an indexing rotary motor 25. The indexing rotation motor 25 is fixed to the base 1. The indexing rotary shaft 24 is rotatably attached to the base 1 via a bearing 41. The index rotation motor 25 causes the multipole armature to be indexed and rotated to a pole 29 to be wound next after being wound around a certain pole 29.
[0025]
2A and 2B are a plan view and a side view of the winding head 4, respectively. At the start of winding, the former guide 7 moves to the pole inner peripheral side 29a, and the side guide 8 tries to advance to the pole inner peripheral side 29a by the spring 13 in accordance with the movement, but hits the flange 30 by the stopper portion 8a of the side guide 8. Therefore, it cannot proceed to the pole inner peripheral side 29a.
[0026]
FIGS. 3A and 3B are a plan view and a side view of the winding head 4. As winding is performed, the former base 9 moves away from the pole inner peripheral side 29 a together with the former guide 7. When the stopper member 12 hits the former base 9, the side guide 8 moves away together with the former guide 7. At this time, the guide surface 7a of the former guide 7 and the guide surface 8b of the side guide are in the same plane.
[0027]
4 and 5 are operation process diagrams during winding. As shown in FIG. 4A, the side guide 8 does not advance to the pole inner peripheral side 29a by the stopper portion 8a, only the former guide 7 advances to the pole inner peripheral side 29a, and guides the wire W to the pole inner peripheral side 29a. To do. That is, in this state, the wire W is guided to the pole portion 29 only by the former guide 7.
[0028]
As shown in FIG. 4B, the winding head 4 moves away from the pole inner peripheral side 29a, and winding is performed. The guide surface 7a of the former guide 7 and the guide surface 8b of the side guide 8 coincide with each other when the opening / closing operation surface 7b of the former guide 7 hits the flange 30. That is, in this case, the wire W is guided to the pole 29 by both the former guide 7 and the side guide 8.
[0029]
As shown in FIG. 4C, when the winding is further advanced, the former guide 7 is opened by the opening / closing operation surface 7b of the former guide 7 hitting the flange 30. However, the wire rod that the side guide 8 tries to enter into the gap is guided to an appropriate position by which the wire rod W can be aligned and wound by the guide surface 8 b of the side guide 8. That is, the wire W is guided to the pole 29 only by the side guide 8.
[0030]
As shown in FIG. 4 (d), the guide surface 8 b of the side guide 8 guides the wire W until the winding of the first layer is completed, that is, until the wire W comes into contact with the flange 30. When the winding of the first layer is finished, the winding head 4 starts to approach the pole inner peripheral side 29a while winding the second layer.
[0031]
As shown in FIG. 5A, also in the second layer, when the opening / closing operation surface 7b of the former guide 7 is in contact with the flange 30, the guide surface 8b of the side guide 8 should wind the wire W. Guide to pole 29.
[0032]
As shown in FIGS. 5B and 5C, when the opening / closing operation surface 7 b of the former guide 7 leaves the flange 30, the wire W is aligned and wound around the pole 29 to be wound by the guide surface 7 a of the former guide 7. To go.
[0033]
Thus, the guide surface 7a of the former guide guides the wire W to the pole 29 until the opening / closing operation surface 7b of the former guide 7 hits the flange 30, and the guide surface 8b of the side guide 8 is the opening / closing operation surface 7b of the former guide 7. At the distance that is opened by hitting the heel 30, the wire W is guided to the pole 29 instead of the former guide 7. Therefore, the wire W can be accurately controlled without entering the gap generated when the former guide 7 is opened, and aligned winding can be performed in the vicinity of the flange 30.
[0034]
Next, another embodiment of the present invention is shown in FIG. The winding machine 100 is mainly composed of a base 1, a movable body 2, a spindle shaft 3, a winding head 4, a flyer 5, and a multipole armature holding means 6. In this embodiment, the side guide 8 of the winding head 4 is configured to be movable in the axial direction of the spindle shaft 3 by a transmission rod 26 (shaft-like member) penetrating the inside of the spindle shaft 3. The side guide 8 is fixed to the transmission rod 26. A ball screw shaft 32 a fixed to the output shaft 31 a of the side guide moving motor 31 rotates in the transmission rod 26, and the transmission rod 26 can be moved through the nut portion 32 of the ball screw.
[0035]
FIG. 7 is a sectional view of the winding head 4. The side guide 8 is movable in the direction of the spindle shaft 3 by the transmission rod 26 penetrating the inside of the spindle shaft 3, but the winding head 4 is not rotatable, and therefore the transmission rod fixed to the bearing 33 and the transmission rod 26. The spindle shaft 3 is made unrotatable by the side bearing support member 34a and the side guide side bearing support member 34b. The side guide side bearing support member 34b is fixed to the side guide 8 with a screw or the like via a transmission rod 26a movable in the winding head 4.
[0036]
Here, although it is not always easy to set the positional relationship between the guide surface 8b of the side guide 8 and the guide surface 7a of the former guide 7, the side guide 8 and the former guide 7 move by mutually independent drive means. For this reason, in the positional relationship between the guide surface 8b of the side guide 8 and the guide surface 7a of the former guide 7, it becomes easy to make arbitrary adjustments that meet various conditions.
[0037]
Next, still another embodiment of the present invention is shown in FIG. The winding machine 100 is mainly composed of a base 1, a movable body 2, a spindle shaft 3, a winding head 4, a flyer 5, and a multipole armature holding means 6. In this embodiment, the side guide 8 of the winding head 4 is configured to be movable in the axial direction of the spindle shaft 3 by a transmission rod 26 penetrating the inside of the spindle shaft 3. Further, the opening and closing of the former guide 7 is not performed by using the pneumatic cylinder 21 but by moving the opening and closing shaft 20 in the direction of the spindle shaft 3 using the opening and closing shaft moving motor 35 which is an opening and closing drive unit. The former 20 is opened and closed around the axis of the former base 9. The opening / closing shaft 20 is configured to be movable in the axial direction of the spindle shaft 3 via the ball screw nut portion 36 by rotation of a ball screw shaft 36a fixed to the output shaft 35a of the opening / closing shaft moving motor.
[0038]
Therefore, the rotation of the flyer 5, the advance / retreat of the former guide 7, the opening / closing of the former guide 7, and the advance / retreat of the side guide 8 can be driven individually. As a result, the former guide 7 can be opened and closed without using the poles 30 of each pole of the multi-pole armature 28. Therefore, since the flange 30 is not bent by the opening / closing action surface 7b of the former guide 7, the defect of the multipole armature 28 is eliminated. Furthermore, since the opening / closing operation surface 7b of the former guide 7 does not have to be inclined, the effective range of the winding section of the former guide 7 increases.
[0039]
A fourth embodiment of the present invention is shown in FIG. The winding machine 200 is mainly composed of a base 1, a movable body 202, a spindle shaft 203, a winding head 204, a flyer 205, and multipole armature holding means 6. The winding head 204 is mainly composed of a former guide 7, a side guide 8, and a former base 209. This winding machine 200 has substantially the same structure as the winding machine 100 shown in the figure, but the points described below are different.
[0040]
FIG. 10 is an enlarged cross-sectional view around the former guide 7 and the side guide 8. In the former guide 7, the linear guide 210 is fixed to the former base 209 side with screws or the like, and the linear rail 211 corresponding to the linear guide 210 is fixed to the former base 209 with screws or the like. The former guide 7 is supported via a linear rail 211 on the former base 209 so as to be openable and closable in a direction that intersects the axis direction of the spindle shaft 203 and is orthogonal to the present embodiment. An elastic member (biasing means) such as a spring 261 is provided between the former guides 7 and biases the former guides 7 in a closing direction. An open / close shaft 220 for opening / closing the former guide 7 is provided inside the spindle shaft 203 for rotating the flyer 205. The opening / closing shaft 220 is moved in the direction of the spindle shaft 203 by using an opening / closing shaft moving motor 35 (see FIG. 9) fixed to the movable body 202 (via a member not shown in FIG. 9), thereby opening and closing the opening / closing shaft end. The taper 220a is opened and closed. The open / close shaft 220 is rotated by a ball screw shaft 36a (see FIG. 9) fixed to the output shaft 35a (see FIG. 13) of the open / close shaft moving motor 35 via a nut portion 36 (see FIG. 9) of the ball screw. It is configured to be movable in the axial direction of the spindle shaft 203.
[0041]
As the opening / closing shaft 220 advances, the taper portion 220a at the end of the opening / closing shaft 220 enters or leaves the cam follower portions 207c, 207c (a pair) formed at the rear end portion of the former guide 7 as the opening / closing shaft 220 advances. As a result, the former guides 7 and 7 can be opened and closed in a direction orthogonal to the axial direction of the spindle shaft 203 via the linear rail 211 on the former base 209. The cam follower portions 207c and 207c are formed to have a spherical shape or other convex curved surface. Of course, not only the cam mechanism as described above but also a link mechanism (not shown) may be used for opening and closing.
[0042]
With such a structure, the former guide 7 is provided with a form protruding in the direction of the multipole armature 28 at the tip, that is, the opening / closing operation surface 7b of the former guide 7 is provided vertically, so that the thickness t of the contact portion 7f is reduced. Since the side guide 8 only needs to be inserted in the inner circumferential direction of the pole 29 by the thickness t, the distance that the former guide 7 guides the wire W is increased, and the side guide 8 is inserted deeply. There is no need. Further, even if the diameter of the wire W changes, the former guide 7 and the side guide 8 move independently, so that it is possible to easily cope with it.
[0043]
Next, as shown in FIG. 11, a spindle shaft 203 as a rotating shaft for rotating the flyer 205 is rotatable inside the former base 209, and a bearing 240 or the like is prevented so that the former base 209 is not rotated by the rotation. It is supported by. And the transmission shaft 226 for moving the side guide 8 is provided in the inside. The transmission shaft 226 is attached via a bearing 235 for preventing the side guide moving member 234 from being rotated, and the side guide moving member 234 moves the side guide 8 in the axial direction of the transmission shaft 226 via the arm 233. Making it possible. Further, an opening / closing shaft 220 passes through the transmission shaft 226 and is provided therein. The opening / closing shaft 220 is provided with a tapered portion 220 a at the tip thereof, and is supported via a bearing 237 so as not to rotate with the opening / closing shaft 220. As a result, the spindle shaft 203, the transmission shaft 226, and the opening / closing shaft 220 are coaxial, so that the spindle shaft 203 can be reduced in diameter, and the winding machine 200 itself can be downsized.
[0044]
Returning to FIG. 9, a connection key 250 for rotating the spindle shaft 203, the transmission shaft 226, and the opening / closing shaft 220 at the same time is provided and fixed to the spindle shaft 203. In order to allow movement in the axial direction, grooves 220a and 226a are provided in the opening / closing shaft 220 and the transmission shaft 226, respectively. Synchronous rotation is possible. Further, the movable body 202 is reduced in size by the reduction in the diameter of the spindle shaft 203, and the spindle shaft rotating motor 14 that rotates the spindle shaft 203 can also be reduced in size.
[0045]
And the operation | movement process of this winding machine 200 is demonstrated using FIGS. Here, a direction approaching the multipolar armature 28 is defined as a forward direction, and a direction away from the multipole armature 28 is defined as a backward direction. First, when the former base 209 advances, the opening / closing shaft 220 advances so that the contact portion 7f of the former guide 7 does not contact the flange 30, and the linear guide 210 moves along the linear rail 211 of the former base 209. 7 moves away. At this time, the side guide 8 is arranged at an arbitrary position, in this embodiment, so as to overlap the pole 29 by the thickness t of the contact portion 7 f of the former guide 7.
[0046]
Next, when the former guides 7 and 7 are moved to the innermost part of the multipole armature 28 and approach or come into contact with the pole 29, the flyer 205 is rotated by the rotation of the spindle shaft 203, and the wire W is wound around the pole 29. start. The former base 209 moves backward so that the first-layer winding moves from the inner circumference side to the outer circumference side of the pole 29. Since the contact portion 7f of the former guide 7 does not come into contact with the flange 30, the opening / closing shaft 220 advances, the tapered portion 220a contacts the cam follower portions 207c and 207c of the former guide 7, and the former guides 7 and 7 are separated from each other. Let At substantially the same time, the wire W is guided from the guide surface 7a of the former guide 7 by the guide surface 8b of the side guide, and winding is performed.
[0047]
When the first layer winding is completed, the second layer winding is performed continuously. In this embodiment, the wire W is wound from the outer peripheral side of the pole 29 toward the inner peripheral side. In the second layer, the process performed in the first layer is reversed. To explain, the wire W is wound on the wire W wound on the first layer by the side guide 8, and then the contact portion 7 f of the former guide 7 is a gap smaller than the diameter of the wire W on the first layer of wire W. As the wire guide W is guided by the former guide 7, the wire W is wound. In the third and subsequent layers, the winding is performed in the same manner. When the predetermined number of turns is reached, the winding is finished and the former base 9 is retracted. Similarly, the other poles 29 are wound, and all the poles 29 of the multipole armature 28 are wound.
