  However, in the winding device described in Patent Document 1, in order to rotate the nozzle in the circumferential direction of the stator, it is necessary to rotate the two shaft rotation motors at the same speed. If the speed is slightly different, the nozzle moves in the radial direction, and stable winding cannot be performed on the magnetic pole of the stator.

  Also, in order to move the nozzle in the radial direction of the stator, it is necessary to rotate the two shaft rotation motors at different speeds. Therefore, when the head support shaft is rotating at a high speed, the traverse shaft is In some cases, it is necessary to rotate at the above speed. In this case, the shaft rotation motor of the traverse shaft may not be able to follow the rotation speed of the head support shaft, and stable winding cannot be performed on the magnetic poles of the stator.

  According to the present invention, by rotating one of the first shaft and the second shaft about the axis, the rotation is transmitted to the other shaft. Can be rotated at the same speed, and even if the other axis is rotated about the axis, the rotation is not transmitted to one axis, so the other axis rotates relative to the other axis. Can be moved. Therefore, stable winding can be performed on the magnetic pole.

  Embodiments of the present invention will be described below with reference to the drawings.

  A winding apparatus 100 according to an embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a perspective view showing the winding device 100, FIG. 2 is a cross-sectional view showing the winding device 100, and FIG. 3 is an exploded perspective view showing the periphery of the head.

  The winding device 100 is a device that automatically winds the wire 2 around the magnetic pole 1, and in the present embodiment, a device that winds the wire 2 around the magnetic pole 1 of the stator 3 in the inner rotor type motor will be described. .

  The winding device 100 includes a stator support base 4 that supports the stator 3 and an indexing motor 5 that rotationally drives the stator support base 4. The stator support 4 and the indexing motor 5 are arranged on the upper stage 7 of the gantry 6.

  The stator 3 includes an annular yoke portion 3a and a plurality of magnetic poles 1 extending from the inner periphery of the yoke portion toward the center of the stator 3, and a wire rod 2 is wound around each magnetic pole 1 to form a stator coil.

  The stator support 4 has teeth 4 a meshing with a gear 9 connected to the output shaft of the indexing motor 5 on the outer periphery, and rotates by driving the indexing motor 5.

  The winding device 100 includes a plurality of nozzles 11 that feed out the wire 2, a head 12 that supports the plurality of nozzles 11, a head support shaft 13 as a first shaft that supports the head 12, and a coaxial with the head support shaft 13. A traverse shaft 14 as a second shaft disposed above, a shaft connection mechanism 15 as a shaft connection means for connecting the head support shaft 13 and the traverse shaft 14, and the head 12 are rotated about the axis of the head support shaft 13. A head rotation mechanism 16 as a moving head rotation means, a head axis direction movement mechanism 17 as a head axis direction movement means for moving the head 12 in the axial direction of the head support shaft 13, and the nozzle 11 as a head support shaft 13. And a nozzle moving mechanism 18 as nozzle moving means for moving in the axial radius direction.

  The winding device 100 operates the head rotating mechanism 16, the head axial direction moving mechanism 17, and the nozzle moving mechanism 18 to operate the nozzle 11 to wind the wire 2 fed from the nozzle 11 around the magnetic pole 1. To do. Below, the detailed structure of the winding apparatus 100 is demonstrated.

  The plurality of nozzles 11 are held by the nozzle holder 21 and arranged to extend radially toward the magnetic pole 1 of the stator 3.

  The head 12 includes a disc-shaped guide plate 22 that is disposed in the inner opening of the stator 3 and is concentric with the stator 3, and the nozzle holder 21 is supported by the guide plate 22.

  The head support shaft 13 has a cylindrical shape, and one end is coupled to the center of the guide plate 22 of the head 12. Therefore, when the head support shaft 13 rotates about the axis, the head 12 also rotates about the axis of the head support shaft 13. A plurality of wires 2 supplied from a wire supply source (not shown) are introduced into the head support shaft 13 from the other end of the head support shaft 13, pulled out from an opening 13 b provided near the head 12, and held by the nozzle 11. Is done.

  The traverse shaft 14 has a cylindrical shape, and is arranged in such a manner that the head support shaft 13 is inserted through the cylinder of the traverse shaft 14. The traverse shaft 14 and the head support shaft 13 are connected by fitting a groove 14 a provided on the inner periphery of the traverse shaft 14 and a convex portion 13 a provided on the outer periphery of the head support shaft 13. As a result, the traverse shaft 14 is in a state where the rotation of the shaft center is independent of the head support shaft 13 and the axial direction is coupled.

  One end of the traverse shaft 14 is coupled to the center of the disc-shaped cam plate 23. Accordingly, when the traverse shaft 14 rotates about the axis, the cam plate 23 rotates about the axis of the traverse shaft 14. The cam plate 23 is disposed in parallel to the guide plate 22 on the opposite side of the guide plate 22 via the nozzle holder 21, and is rotated relative to the guide plate 22 integral with the head support shaft 13. The nozzle 11 is configured to move in the axial radial direction of the head support shaft 13.

  A specific mechanism for allowing the nozzle 11 to move in the axial radius direction of the head support shaft 13 will be described with reference to FIG. The guide plate 22 coupled to one end of the head support shaft 13 is formed with guide grooves 51 extending radially in the same radial direction as the number of nozzles 11. The cam plate 23 connected to one end of the traverse shaft 14 is formed with a cam groove 52 that is curved in the outer edge direction from the vicinity of the center and extends in a spiral shape.

  The nozzle holder 21 that holds the nozzle 11 includes a slide portion 53 that is slidably fitted in the guide groove 51 of the guide plate 22, and a roller-shaped cam follower 54 that is engaged with the cam groove 52 of the cam plate 23. As a result, the cam follower 54 moves along the spiral cam groove 52 as the cam plate 23 rotates relative to the guide plate 22, and the nozzle holder 21 moves along the guide groove 51 in the radial direction of the guide plate 22. That is, it moves in the axial radial direction of the head support shaft 13.

  As described above, when the traverse shaft 14 is rotated relative to the head support shaft 13, the nozzle 11 moves in the axial radial direction of the head support shaft 13, and the traverse shaft 14 is synchronized with the head support shaft 13. If rotated, the nozzle 11 does not move in the radial direction of the head support shaft 13.

  The shaft connection mechanism 15 connects the first gear mechanism 25 connected to the head support shaft 13, the second gear mechanism 26 connected to the traverse shaft 14, and the first gear mechanism 25 and the second gear mechanism. And a connecting shaft 27 as a connecting member.

  The first gear mechanism 25 includes a sun gear 25a having teeth formed on the outer periphery, an annular internal gear 25b surrounding the sun gear 25a and teeth formed on the inner periphery, and the sun gear 25a and the internal gear 25b. A plurality of planetary gears 25c that are disposed between and formed on the outer periphery mesh with both teeth. The head support shaft 13 is inserted through the sun gear 25 a, and the inner periphery of the sun gear 25 a is coupled to a spline 28 formed on the outer periphery of the head support shaft 13. The internal gear 25b is fixed to the upper stage 7 of the gantry 6 in a non-rotatable manner by fastening bolts 60.

  The second gear mechanism 26 includes a sun gear 26a having teeth formed on the outer periphery, an annular internal gear 26b enclosing the sun gear 26a and having teeth formed on the inner periphery, and the sun gear 26a and the internal gear 26b. A plurality of planetary gears 26c that are disposed between and formed on the outer periphery mesh with both teeth. The traverse shaft 14 is inserted through the sun gear 26 a, and the inner periphery of the sun gear 26 a is coupled to a spline 29 formed on the outer periphery of the traverse shaft 14.

  The connecting shaft 27 inserts both the planetary gear 25 c in the first gear mechanism 25 and the planetary gear 26 c in the second gear mechanism 26 through the rolling bearing 61 and connects the two. Thereby, the planetary gear 25c and the planetary gear 26c can revolve around the sun gear 25a and the sun gear 26a in a synchronized manner, and can rotate independently of each other.

  Thus, by configuring the shaft coupling mechanism 15, when the sun gear 25a of the first gear mechanism 25 is rotated, the head support shaft 13 spline-coupled to the inner periphery of the sun gear 25a rotates about the axis. . Since the internal gear 25b of the first gear mechanism 25 is fixed, the planetary gear 25c revolves along the inner periphery of the internal gear 25b while rotating.

  As the planetary gear 25c of the first gear mechanism 25 revolves, the planetary gear 26c of the second gear mechanism 26 connected to the planetary gear 25c by the connecting shaft 27 also rotates while the inner periphery of the internal gear 26b. Revolve along. As a result, the planetary gear 26a of the second gear mechanism 26 rotates, and the traverse shaft 14 splined to the inner periphery of the planetary gear 26a also rotates about the axis. In this way, the rotation in the first gear mechanism 25 is transmitted to the second gear mechanism 26. At this time, the internal gear 26b of the second gear mechanism 26 is stationary without rotating.

  When the internal gear 26b of the second gear mechanism 26 is rotated, the planetary gear 26c of the second gear mechanism 26 rotates and the sun gear 26a of the second gear mechanism 26 rotates. As a result, the traverse shaft 14 splined to the inner periphery of the sun gear 26a rotates about the axis. At this time, since both the internal gear 26b and the sun gear 26a rotate, the planetary gear 26c does not revolve. For this reason, the rotation in the second gear mechanism 26 is not transmitted to the first gear mechanism 25.

  As described above, the shaft coupling mechanism 15 rotates the sun gear 25a in the first gear mechanism 25 and rotates the head support shaft 13 about the axis, so that the traverse shaft 14 is also synchronized with the head support shaft 13. It can be rotated around the axis. Further, the traverse shaft 14 can be rotated relative to the head support shaft 13 by rotating the internal gear 26 b in the second gear mechanism 26 and rotating the traverse shaft 14 about the axis.

  The head rotation mechanism 16 is coupled to the head support shaft rotation motor 35, the cam follower 33 connected to the output shaft 34 of the head support shaft rotation motor 35, and the sun gear 25 a of the first gear mechanism 25. And a cam guide 31 guided in a guide groove 32 formed in the above. The head support shaft rotation motor 35 is supported by a housing 36 connected to the upper stage 7 of the gantry 6.

  When the cam follower 33 is rotated by the rotation of the head support shaft rotation motor 35, the cam guide 31 is guided along the guide groove 32 of the cam follower 33. As a result, the head support shaft 13 splined to the sun gear 25a reciprocates around the axis, and the head 12 at the end of the head support shaft 13 also reciprocates around the axis.

  The head axis direction moving mechanism 17 includes a head support shaft moving motor 37, a support plate 38 that supports the head support shaft moving motor 37, a disk 40 connected to the output shaft 39 of the head support shaft moving motor 37, and a link 41. One end 41a of the link 41 is rotatably connected to the outer edge of the disc 40, and the other end 41b is rotatably connected to the vicinity of the end opposite to the end of the head support shaft 13 where the head 12 is provided. The support plate 38 is disposed on the lower stage 8 of the gantry 6.

  When the disc 40 is rotated by the rotation of the head support shaft moving motor 37, the one end 41 a of the link 41 moves along the outer edge of the disc 40. As a result, the head support shaft 13 linked to the other end 41b of the link 41 reciprocates in the axial direction, and the head 12 at the end of the head support shaft 13 also reciprocates in the axial direction. The traverse shaft 14 is reciprocated in the axial direction together with the head support shaft 13 because the traverse shaft 14 is connected to the head support shaft 13 in the axial direction by fitting the groove 14a and the convex portion 13a. Thus, the head axis direction moving mechanism 17 is a crank mechanism that converts the rotational movement of the disc 40 into the reciprocating movement of the head support shaft 13 and the traverse shaft 14.

  The head axis direction moving mechanism 17 may be configured to reciprocate the head support shaft 13 and the traverse shaft 14 using a motor and a ball screw.

  The nozzle moving mechanism 18 is a mechanism that allows the nozzle 11 to move in the axial radial direction of the head support shaft 13, that is, a guide plate 22, a guide groove 51, a cam plate 23, a cam groove 52, a slide portion 53, and a cam follower. In addition to 54, a traverse shaft rotating mechanism 43 that rotates the traverse shaft 14 relative to the head support shaft 13 is provided.

  The traverse shaft turning mechanism 43 includes a traverse shaft turning motor 44, a pulley 46 connected to the output shaft 45 of the traverse shaft turning motor 44, a pulley 46 and an internal gear 26 b of the second gear mechanism 26. And a belt 47 to be connected. The traverse shaft rotation motor 44 is disposed on the upper stage 7 of the gantry 6.

  When the pulley 46 is rotated by the rotation of the traverse shaft rotation motor 44, the rotation is transmitted to the internal gear 26b of the second gear mechanism 26 via the belt 47, and the internal gear 26b is rotated. Thereby, the planetary gear 26c of the second gear mechanism 26 rotates and the sun gear 26a of the second gear mechanism 26 rotates. Then, the traverse shaft 14 splined to the inner periphery of the sun gear 26a rotates about the axis. At this time, since the planetary gear 26 c does not revolve, the rotation in the second gear mechanism 26 is not transmitted to the first gear mechanism 25. Accordingly, the traverse shaft 14 rotates relative to the head support shaft 13, and the nozzle 11 moves in the axial radius direction of the head support shaft 13.

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

  First, the stator 3 is fixed to the stator support 4 and the indexing motor 5 is driven to place the stator 3 at a predetermined position.

  A plurality of wires 2 supplied from a wire supply source are introduced into the head support shaft 13 from the lower end of the head support shaft 13 and pulled out from an opening 13 b provided near the head 12. Further, it is pulled out from the nozzle tip through the nozzle 11. The wire 2 drawn from the tip of the nozzle 11 is held by a clamp (not shown).

  Since the winding device 100 includes the plurality of nozzles 11, the winding to the plurality of magnetic poles 1 is simultaneously performed. The winding of the wire 2 around the magnetic pole 1 moves the nozzle 11 around the magnetic pole 1 and winds the wire 2 around the magnetic pole 1, and moves the nozzle 11 in the longitudinal direction of the magnetic pole 1 to move the wire 2 along the length of the magnetic pole 1. This is done by combining the operation of feeding the wire diameter in the direction. That is, the wire 2 is wound around the magnetic pole 1 by repeating the operation of feeding the wire 2 around the magnetic pole 1 once and then feeding the wire 2 by the wire diameter in the longitudinal direction of the magnetic pole 1.

  Further, the movement of the nozzle 11 around the magnetic pole 1 is performed by combining the operation of moving the nozzle 11 in the width direction of the magnetic pole 1 and the operation of moving the nozzle 11 in the height direction of the magnetic pole 1.

  First, the operation of moving the nozzle 11 in the width direction of the magnetic pole 1 will be described. By driving the head support shaft turning motor 35 in the head turning mechanism 16 and rotating the cam follower 33, the cam guide 31 is guided along the guide groove 32 of the cam follower 33, and the sun gear 25 a of the first gear mechanism 25. The head support shaft 13 reciprocates around the shaft center. As a result, the head 12 also reciprocates around the axis, so that the nozzle 11 supported by the head 12 reciprocates in the width direction of the magnetic pole 1.

  At this time, since the rotation of the sun gear 25a of the first gear mechanism 25 is transmitted to the second gear mechanism 26 by the shaft coupling mechanism 15 as described above, the spline is splined to the sun gear 26a of the second gear mechanism 26. The coupled traverse shaft 14 also reciprocates in synchronization with the head support shaft 13. Therefore, since the rotation of the traverse shaft 14 does not deviate from the rotation of the head support shaft 13, the nozzle 11 does not move in the axial radius direction of the head support shaft 13 and stable winding is performed. Can do.

  Next, the operation of moving the nozzle 11 in the height direction of the magnetic pole 1 will be described. The disk 40 is rotated by driving a head support shaft moving motor 37 in the head axis direction moving mechanism 17, and the rotation is converted into a reciprocating motion in the axial direction of the head support shaft 13 and the traverse shaft 14 by a crank mechanism. Accordingly, the head 12 also reciprocates in the axial direction, so that the nozzle 11 supported by the head 12 reciprocates in the height direction of the magnetic pole 1.

  In this way, by controlling the driving of the head support shaft rotating motor 35 and the head support shaft moving motor 37, the nozzle 11 can be moved around the magnetic pole 1, and the wire 2 is wound around the magnetic pole 1. be able to.

  Next, the operation of moving the nozzle 11 in the longitudinal direction of the magnetic pole 1 will be described. By driving the traverse shaft rotation motor 44 in the traverse shaft rotation mechanism 43 and rotating the internal gear 26b of the second gear mechanism 26, the sun gear 26a of the second gear mechanism 26 is rotated, and the sun The traverse shaft 14 that is splined to the gear 26a is rotated about the axis.

  At this time, the planetary gear 26c of the second gear mechanism 26 rotates as described above but does not revolve. For this reason, the rotation of the second gear mechanism 26 is not transmitted to the first gear mechanism 25, and therefore is not transmitted to the head support shaft 13. Therefore, the traverse shaft 14 rotates relative to the head support shaft 13, and the nozzle holder 21 disposed between the guide plate 22 and the cam plate 23 moves along the guide groove 51 of the head support shaft 13. Move in the axial radius direction. Thus, by rotating the traverse shaft rotation motor 44 by a predetermined angle corresponding to the wire diameter of the wire 2, the nozzle 11 moves in the longitudinal direction of the magnetic pole 1 and moves the wire 2 in the longitudinal direction of the magnetic pole 1. Can be sent as much as the wire diameter.

  When driving the traverse shaft rotation motor 44 and driving the wire 2 while driving the head support shaft rotation motor 35 and the head support shaft movement motor 37 and winding the wire 2 around the magnetic pole 1, the traverse shaft rotation is performed. Since the internal gear 26b of the second gear mechanism 26 to which the dynamic motor 44 is coupled is stationary, the wire 2 can be quickly fed by driving the traverse shaft rotation motor 44. That is, it is not necessary to rotate the traverse shaft rotation motor 44 in accordance with the rotation speed of the head support shaft 13, and the traverse shaft 14 is synchronized with the head support shaft 13 by driving the traverse shaft rotation motor 44. A rotation speed that is superimposed on the rotation speed is added, and the head support shaft 13 rotates relative to the rotation speed.

  As described above, the wire 2 can be wound around the magnetic pole 1 by controlling the head support shaft rotation motor 35, the head support shaft movement motor 37, and the traverse shaft rotation motor 44.

  According to the winding device 100 according to the first embodiment described above, when the wire 2 is wound around the magnetic pole 1, the traverse shaft 14 rotates in synchronization with the rotation of the head support shaft 13. There is no deviation in rotation. Further, when the wire 2 is fed in the longitudinal direction of the magnetic pole 1, only the traverse shaft 14 can be rotated, so that the traverse shaft 14 can be easily rotated relative to the head support shaft 13. Therefore, stable winding can be performed on the magnetic pole 1.

  Hereinafter, another aspect of the present embodiment will be described.

  In the present embodiment, the first gear mechanism 25 that fixes the internal gear 25 b of the first gear mechanism 25 in the shaft coupling mechanism 15 so as not to rotate and spline-couples the head rotation mechanism 16 to the head support shaft 13. The traverse shaft turning mechanism 43 of the nozzle moving mechanism 18 is connected to the internal gear 26b of the second gear mechanism 26. However, the internal gear 26b of the second gear mechanism 26 in the shaft coupling mechanism 15 is fixed to be non-rotatable, and the head rotation mechanism 16 is spline-coupled to the traverse shaft 14 to the sun gear 26a of the second gear mechanism 26. It is also possible to connect the traverse shaft rotation mechanism 43 of the nozzle moving mechanism 18 to the internal gear 25b of the first gear mechanism 25.

  That is, when the wire 2 is wound around the magnetic pole 1, the head support shaft 13 is rotated in synchronization with the rotation of the traverse shaft 14, and when the wire 2 is fed in the longitudinal direction of the magnetic pole 1, the head support shaft is rotated. 13 is configured to rotate relative to the traverse shaft 14. Even if comprised in this way, the effect similar to the said embodiment can be acquired.

  The shaft coupling mechanism 15 can also be configured as follows. In the first gear mechanism 25, the sun gear 25 a is fixed in a non-rotatable manner, and the internal gear 25 b is spline-coupled to the head support shaft 13, and the cam guided to the guide groove 32 of the cam follower 33 in the head rotation mechanism 16. The guide 31 is coupled to the internal gear 25b. Further, in the second gear mechanism 26, the pulley 46 in the traverse shaft rotation mechanism 43 is connected to the sun gear 26a, and the internal gear 26b is splined to the traverse shaft 14. Even if comprised in this way, the effect similar to the said embodiment can be acquired.

  The present invention is not limited to the above-described embodiment, and it is obvious that various modifications can be made within the scope of the technical idea.

  The present invention can be applied to a winding device for manufacturing a stator coil.
