Description

  The present invention relates to a coil winding apparatus and a coil winding method.

  A focus coil, a tracking coil, and the like are known as coils used for driving a head in an apparatus for reproducing and recording an optical disk such as a compact disk.

  As a coil winding apparatus for manufacturing this type of coil, an apparatus for manufacturing a plurality of connected coils using a single continuous wire is known, and the present applicant has filed a patent application ( Patent Document 1).

JP-A-9-27435

  In this coil winding apparatus, since a plurality of winding jigs are provided on one spindle, the winding jigs are arranged so as to be offset from the rotation center of the spindle. Therefore, the winding jig rotates so as to draw a circle around the spindle axis. As a result, the feeding speed of the wire fed from the nozzle during spindle rotation changes depending on the distance between the winding jig and the nozzle. That is, as the distance between the winding jig and the nozzle increases, the wire feeding speed increases and the tension of the wire increases. Further, as the distance between the winding jig and the nozzle becomes shorter, the feeding speed of the wire becomes slower and the tension of the wire becomes smaller.

  As described above, since the tension applied to the wire varies during one rotation of the spindle, in the case of a thin wire, disconnection may occur when the rotation speed of the spindle is increased. Therefore, there is a limit to increasing the rotation speed of the spindle, and efficient winding cannot be performed.

  Moreover, since the wire is wound around the winding jig at a portion where the tension of the wire is high, and the wire is wound around the winding jig at a portion where the tension is low, it is difficult to obtain a desired coil shape.

  The present invention has been made in view of the above problems, and it is an object of the present invention to provide a coil winding apparatus and a coil winding method capable of obtaining a desired coil shape and performing winding efficiently. And

  The present invention is a coil winding device that winds a connection coil in which a plurality of coils are connected, and supports a spindle shaft that can rotate around an axis, a wire supply member, and the rotation of the spindle shaft. A flyer that revolves around the spindle axis, a plurality of winding jigs around which wire rods are wound, and a winding jig feed that sequentially sends the plurality of winding jigs to a position that is coaxial with and opposite to the spindle axis Means and a winding jig moving means for individually moving the plurality of winding jigs in the axial direction of the spindle shaft.

  According to the present invention, the plurality of winding jigs are sequentially fed to positions concentrically with the spindle shaft, and the wire is fed from the wire supply member supported by the flyer turning around the spindle shaft. The distance between the wound winding jig and the wire supply member is always kept constant during winding. Therefore, since the tension of the wire is kept constant during winding, it is possible to wind at a higher speed and to perform winding efficiently. Further, since the tension of the wire wound around the winding jig is constant, it is easy to obtain a desired coil shape.

  In addition, since there is a winding jig moving means that individually moves the winding jig in the axial direction of the spindle shaft, the winding jig to be wound among the plurality of winding jigs is arranged at a position that does not interfere with other winding jigs. Thus, winding can be performed efficiently.

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

  A coil winding apparatus 100 according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 is a perspective view showing the coil winding device 100, and FIG. 2 is a cross-sectional view showing the coil winding device 100. In the following, the “X-axis direction” refers to the axial direction of the spindle axis, and the “Y-axis direction” refers to the horizontal direction perpendicular to the spindle axis.

  The coil winding device 100 is a device that winds a connecting coil in which a plurality of coils are connected, and manufactures a connecting coil by winding one continuous wire 1 around a plurality of winding jigs 2 in order. Is. In this embodiment, the case where four winding jigs 2 (2a to 2d) are provided is shown, but the number of winding jigs 2 may be set so as to correspond to a desired number of coils (number of stations). . Moreover, you may make it select the winding jig | tool 2 to be used from the some winding jig | tool 2 so that it may become a desired number of coils.

  The coil winding apparatus 100 is disposed to face the wire winding mechanism 101 that winds the wire 1 from a wire supply source (not shown) around the winding jig 2, and the wire 1 is wound. And a winding jig adjusting mechanism 102 for adjusting the arrangement of the winding jig 2 to be wired.

  The wire rod winding mechanism 101 supports a spindle shaft 3 that rotates about an axis, a spindle shaft rotation mechanism 4 that rotates the spindle shaft 3, and a nozzle 5 as a wire rod supply member, and a spindle that rotates along with the rotation of the spindle shaft 3. And a flyer 6 that pivots about an axis 3.

  The winding jig adjusting mechanism 102 includes a winding jig feeding mechanism 8 as a winding jig feeding means for sequentially feeding the winding jig 2 to a position that is coaxial with the spindle shaft 3 and confronts it.

  Winding by the coil winding device 100 is performed by operating the wire winding mechanism 101 and the winding jig adjusting mechanism 102 in synchronization. Specifically, in the winding jig feeding mechanism 8 of the winding jig adjusting mechanism 102, one of the plurality of winding jigs 2a to 2d, for example, the winding jig 2a is coaxial with the spindle shaft 3 and confronts it. Place it at the position you want. Then, the wire rod winding mechanism 101 rotates the spindle shaft 3 around the axis, thereby turning the flyer 6 around the spindle shaft 3 and winding the wire 1 fed from the nozzle 5 around the winding jig 2a. After the winding to the winding jig 2a is completed, the winding jig 2 is fed by the winding jig feed mechanism 8, and the winding jig 2b adjacent to the winding jig 2a is coaxial with the spindle shaft 3 and at a position facing it. Deploy. Then, the wire 1 is wound around the winding jig 2b by the wire winding mechanism 101. By repeating this operation, an arbitrary number of connected coils can be obtained from one continuous wire 1.

  Below, the detailed structure of the wire winding mechanism 101 and the winding jig adjustment mechanism 102 is demonstrated.

  First, the wire winding mechanism 101 will be described. A head moving mechanism 11 to be described later is disposed on a base 10 that is a base of the coil winding apparatus 100, and a head mounting table 12 is fixed on the head moving mechanism 11. The spindle shaft 3 is supported by a head 13 mounted on the head mounting table 12 via a bearing 14. The bearing 14 is configured to be capable of relative rotation with respect to the head 13 of the spindle shaft 3 and relative movement in the axial direction.

  The spindle shaft 3 has a cylindrical shape, and the wire rod 1 supplied from the wire rod supply source is guided to the nozzle 5 through the guide hole 3 b formed in the body portion 3 a of the spindle shaft 3.

  The spindle shaft rotation mechanism 4 transmits the rotation of the spindle motor 16 to the spindle shaft 3 via the rotation transmission mechanism 15. The spindle motor 16 is attached to the side wall of the head 13 so that the output shaft 16 a extends in parallel with the spindle shaft 3.

  The rotation transmission mechanism 15 includes a pulley 17 attached to the output shaft 16 a of the spindle motor 16, and a pulley 19 connected to the pulley 17 via a belt 18. A spline 3a is formed at the end of the spindle shaft 3, and the pulley 19 is splined coaxially with the spline shaft 3 via the spline 3a. As a result, the spindle shaft 3 rotates in synchronization with the rotation of the spindle motor 16 and moves slidably with respect to the pulley 19 in the axial direction.

  A disc-shaped flyer support plate 21 that supports the flyer 6 is coaxially connected to the spindle shaft 3 at an end of the spindle shaft 3 that faces the winding jig 2. The flyer 6 is an arm-shaped member, and supports the nozzle 5 that feeds the wire on the distal end side. As a result, the flyer support plate 21 rotates with the rotation of the spindle shaft 3, and the flyer 6 rotates about the spindle shaft 3.

  The flyer 6 is configured to be movable in the X-axis direction by the flyer moving mechanism 23. The flyer moving mechanism 23 includes a flyer moving motor 26 attached to the head 13, a ball screw 25 connected to the output shaft of the flyer moving motor 26 and extending parallel to the spindle shaft 3, and the ball screw 25 screwed together. The spindle shaft 3 includes a moving plate 24 that passes through the bearing 27.

  The bearing 27 is configured such that the spindle shaft 3 can rotate relative to the moving plate 24 while the movement in the axial direction is integrated. As a result, when the moving plate 24 moves in the X-axis direction by driving the flyer moving motor 26, the spindle shaft 3 also moves in the axial direction along with the movement of the moving plate 24, and the flyer 6 via the flyer support plate 21. Also moves in the X-axis direction.

  Since the nozzle 5 supported at the tip of the flyer 6 by the flyer moving mechanism 23 can be moved in the X-axis direction, that is, the axial direction of the winding jig 2, the wire rod is fed when winding the winding jig 2. Can do.

  As described above, the flyer 6 can be turned around the spindle shaft 3 by the spindle shaft rotating mechanism 4 and can be moved in the axial direction of the spindle shaft 3 by the flyer moving mechanism 23.

  A center bar 30 that is a rod-like member is inserted through the hollow portion of the spindle shaft 3. The center bar 30 is held via a bearing 32 disposed on the inner periphery of the spindle shaft 3, and is inserted through a through hole 21 a formed in the center axis of the flyer support plate 21 to face the winding jig 2. The center bar 30 is positioned coaxially with the spindle shaft 3 by the bearing 32 and the through hole 21a.

  The bearing 32 is configured so that the rotation and movement of the spindle shaft 3 are not transmitted to the center bar 30. The center bar 30 is provided with a permanent magnet 31b that attracts the permanent magnet 31a provided on the head 13. Thus, the center bar 30 is disposed so as not to rotate.

  The winding to the winding jig 2 is performed in a state where the winding jig 2 and the center bar 30 are in contact with each other. Thereby, the axial center of the winding jig | tool 2 and the spindle axis | shaft 3 which is the rotation center of the flyer 6 correspond. Thus, the center bar 30 has a function of positioning the winding jig 2 and the rotation center of the flyer 6. Further, the end surface of the center bar 30 functions as a flange that regulates the winding width of the winding jig 2.

  The rotation and movement of the spindle shaft 3 are not transmitted to the center bar 30, and the center bar 30 is connected to the head 13 via permanent magnets 31a and 31b. Therefore, the center bar 30 is moved by moving the head 13. Below, the moving mechanism of the center bar 30 is demonstrated.

  The center bar 30 is moved in the X-axis direction by moving the head 13 in the X-axis direction by the head moving mechanism 11. The head moving mechanism 11 includes a head moving motor 38 disposed on the base 10, a ball screw 37 connected to the output shaft of the head moving motor 38 and extending in parallel with the spindle shaft 3, and the ball screw 37 screwed together. A moving table 36 and a guide rail 35 arranged on the base 10 for guiding the moving table 36 are provided.

  Since the head mounting table 12 is fixed on the moving table 36, when the head moving motor 38 is driven, the head 13 mounted on the head mounting table 12 moves in the X-axis direction. In this way, the center bar 30 is moved in the X-axis direction.

  The center bar 30 is moved in the vertical direction by moving the head 13 in the vertical direction by the vertical movement mechanism 40. The vertical movement mechanism 40 includes a vertical movement motor 41 disposed on the head mounting table 12, a ball screw 42 connected to the output shaft of the vertical movement motor 41 and extending in the vertical direction, and the ball screw 42 screwed together. 13 and a follower 43 fixed to 13. The vertical movement mechanism 40 also includes a guide bar 44 attached to the head mounting table 12 and extending in parallel with the ball screw 42, and a guide 45 fixed to the head 13 and sliding along the guide bar 44.

  As a result, when the vertical movement motor 41 is driven, the head 13 moves away from the head mounting table 12 and is guided by the guide rod 44 and moves up. In this way, the center bar 30 is moved in the vertical direction.

  Next, the winding jig adjustment mechanism 102 will be described. The plurality of winding jigs 2 a to 2 d are individually held by a plurality of wire rod guides 50 (50 a to 50 d), and the wire rod 1 is wound around a portion protruding from the end surface of the wire rod guide 50. Thus, the end surface of the wire guide 50 functions as a collar portion of the winding jig 2. The wire rod guides 50a to 50d are arranged in the Y-axis direction by the holder 58 so that the winding jigs 2a to 2d are aligned with the X-axis direction.

  The holder 58 is moved in the Y-axis direction, which is the direction in which the winding jigs 2 a to 2 d are arranged, by the winding jig feeding mechanism 8 disposed on the base 10. In this way, the holder 58 moves in the Y-axis direction, so that the winding jigs 2a to 2d are sequentially sent to positions that are coaxial with the spindle shaft 3 and face each other.

  In order to wind the wire 1 around the winding jig 2, one of the winding jigs 2 a to 2 d, for example, the winding jig 2 a is opposed to the spindle shaft 3 coaxially, and the flyer 6 is connected to the winding jig 2. Winding is performed by swiveling around 2a. At this time, if the winding jig 2a and the other winding jigs 2b to 2d have the same position in the X-axis direction, the flyer 6 interferes with the adjacent winding jig 2b. Therefore, in order to prevent interference between the flyer 6 and the unwound winding jigs 2b to 2d, the position of the winding jig 2a in the X-axis direction is shifted from the positions of the other winding jigs 2b to 2d. 2a needs to be advanced toward the spindle shaft 3. This operation is performed by a winding jig moving mechanism 60 as a winding jig moving means for individually moving the winding jig 2 in the axial direction of the spindle shaft 3.

  The winding jig 2 is slidably moved in the wire guide 50 by the winding jig moving mechanism 60. A guide portion 59 for guiding the wire 1 to the winding jig 2 during winding is formed in a taper shape on the end surface of the wire guide 50, and the end surface of the wire guide 50 functions as a flange portion of the winding jig 2. To do. Therefore, it is necessary to move the wire guide 50 to an optimum position with respect to the winding jig 2 as the winding jig 2 is moved by the winding jig moving mechanism 60. This operation is performed by a wire rod guide moving mechanism 70 as wire rod guide moving means for individually moving the wire rod guide 50 in the axial direction of the spindle shaft 3.

  The holder 58 is arranged at a predetermined interval in the Y-axis direction via the guide shaft 52, the guide shaft 52 extending in the Y-axis direction and having both ends detachably fixed to both side walls of the housing 53. And a plurality of cover members 51 (51a to 51d) for slidably holding the wire guide 50.

  Since the guide shaft 52 passes through the cover members 51a to 51d, the cover member 51 is restricted from moving in the X-axis direction, but can slide along the guide shaft 52 in the Y-axis direction. . Therefore, by adjusting the interval between the adjacent cover members 51, the interval between the adjacent coils of the connecting coil can be arbitrarily set. At the time of winding on the winding jig 2, the cover member 51 is fixed to the guide shaft 52 by a fastening member (not shown) such as a screw.

  Since the wire guide 50 is slidably held by the cover member 51, the wire guide 50 can be removed from the cover member 51 by removing the guide shaft 52 from the housing 53. Thus, since the wire guide 50 is detachably held by the holder 58, the number of winding jigs 2 can be freely set according to the desired number of connected coils.

  The winding jig feed mechanism 8 is fixed to a holder moving motor 54 disposed on the base 10, a ball screw 55 connected to the output shaft of the holder moving motor 54 and extending in the Y-axis direction, and a lower portion of the holder 58. A follower 56 to which the ball screw 55 is screwed and a guide rail 57 that extends along the ball screw 55 and guides the follower 56 are provided.

  Accordingly, when the holder moving motor 54 is driven, the holder 58 moves in the Y-axis direction along the guide rail 57. In this manner, the winding jigs 2a to 2d are sequentially sent to a position coaxial with the spindle shaft 3 and facing each other.

  Next, the winding jig moving mechanism 60 will be described with reference to FIG. The winding jig 2 is disposed in a through hole 78 that penetrates the wire guide 50 in the X-axis direction, and a rod-shaped member 62 is connected to the back surface of the winding jig 2 via a spring 61. The back surface portion 63 of the rod-shaped member 62 protrudes from the through hole 78 and is connected to the drive mechanism 65.

  The drive mechanism 65 includes a winding jig moving motor 66 attached to the back surface of the casing 53 of the holder 58, a ball screw 67 connected to the output shaft of the winding jig moving motor 66 and extending in the X-axis direction, A screw 67 is screwed and a moving plate 68 connected to the back surface portion 63 of the rod-like member 62 is provided. Thereby, the winding jig 2 can be moved in the X-axis direction by driving the winding jig moving motor 66.

  A dovetail groove is formed in the moving plate 68 in the Y-axis direction, and a back surface portion 63 of the rod-like member 62 is slidably fitted in the dovetail groove. Thus, the rod-shaped member 62 moves in the X-axis direction as the moving plate 68 moves, and can move freely in the Y-axis direction without being constrained by the moving plate 68. Therefore, when adjusting the interval between adjacent cover members 51, the cover member 51 can be moved in the Y-axis direction without being constrained by the drive mechanism 65.

  Next, the wire guide moving mechanism 70 will be described with reference to FIG. The wire guide 50 is disposed through the cover member 51. A flange portion 71 is formed at the rear end portion of the wire guide 50.

  The collar portion 71 functions as a stopper that restricts movement of a predetermined amount or more by contacting the back surface of the cover member 51 when the wire guide 50 moves forward. A spring 72 is interposed between the flange portion 71 and the back surface of the cover member 51.

  The wire rod guide 50 is moved forward toward the spindle shaft 3 by urging the collar portion 71 by the urging mechanism 73. Further, in order to retract the advanced wire rod guide 50, the urging force applied to the collar 71 is released by the urging mechanism 73, and the spring compressed by the collar 71 and the back surface of the cover member 51 when the collar 71 is urged. This is done with a biasing force of 72.

  The urging mechanism 73 has the same configuration as that of the drive mechanism 65, and includes a wire guide moving motor 74, a ball screw 75, and a moving plate 76. When the wire guide moving motor 74 is driven, the moving plate 76 is a buttocks. 71 is energized.

  As described above, the movement of the wire guide 50 by the wire guide moving mechanism 70 is independent of the movement of the winding jig 2 by the winding jig moving mechanism 60. Accordingly, the wire guide 50 is moved relative to the winding jig 2 by the wire guide moving mechanism 70 to adjust the distance between the end face of the wire guide 50 and the end face of the center bar 30 in contact with the winding jig 2. Thus, the winding width dimension of the coil can be adjusted.

  On the base 10 between the wire winding mechanism 101 and the winding jig adjusting mechanism 102, a clamp 80 for holding the wire 1 fed from the nozzle 5 is disposed.

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

  First, by operating the winding jig feeding mechanism 8, the holder 58 is moved in the Y-axis direction so that the winding jig 2 a at the end of the winding jigs 2 a to 2 d faces the spindle shaft 3. As a result, the winding jig 2 a is arranged at the center of rotation of the flyer 6. When the vertical positions of the winding jig 2a and the spindle shaft 3 are deviated, the vertical adjustment mechanism 40 is operated to adjust the position.

  By operating the winding jig moving mechanism 60 corresponding to the winding jig 2a, the winding jig 2a is advanced toward the spindle shaft 3, and the position in the X-axis direction is shifted from the other winding jigs 2b to 2d. Further, by operating the wire guide moving mechanism 70 simultaneously with this operation, the wire guide 50a is also advanced toward the spindle shaft 3, and the amount of protrusion of the winding jig 2a from the end surface of the wire guide 50a is adjusted. This protrusion amount becomes the winding width of the coil.

  Next, by operating the head moving mechanism 11, the center bar 30 connected to the head 13 via the permanent magnets 31a and 31b is moved toward the winding jig 2a, and the end surface of the center bar 30 and the winding jig are moved. 2a is brought into contact with the end face. At this time, since the spring 61 is attached to the back surface of the winding jig 2a, after the center bar 30 is brought into contact with the end surface of the winding jig 2a, the center bar 30 is further moved forward, whereby the winding jig 2a moves backward while compressing the spring 61. Thereby, contact | abutting with the center bar 30 and the winding jig | tool 2a can be made reliable.

  By the above operation, the end face of the wire rod guide 50a is arranged at one end of the winding jig 2a, and the end face of the center bar 30 is arranged at the other end as a flange portion of the winding jig 2a. Will be lined.

  Next, an operation for winding the wire 1 around the winding jig 2a will be described. First, the wire 1 supplied from a wire supply source (not shown) is passed through the nozzle 5, and the tip of the wire 1 is held by the clamp 80.

  The wire 1 fed out from the nozzle 5 is guided to the winding jig 2a through a groove 69 provided on the end surface of the wire guide 50.

  In this state, by rotating the spindle shaft 3 and rotating the flyer 6, the nozzle 5 supported at the tip of the flyer 6 turns around the winding jig 2 a while feeding the wire 1. Since the guide part 59 formed in the wire guide 50a is inclined so as to guide the wire 1 to the winding jig 2a, the wire 1 fed out from the nozzle 5 is wound around the outer periphery of the winding jig 2a.

  Since the winding jig 2a is arranged so that its axial direction coincides with the rotation center of the flyer 6, the tension of the wire 1 wound around the winding jig 2a is kept constant during the winding. Therefore, winding can be performed by rotating the flyer 6 at high speed.

  Further, by operating the flyer moving mechanism 23 during the winding, the flyer 6 is moved in the X-axis direction and fed to the wire 1 wound around the winding jig 2a.

  In addition, hot air is blown against the wire 1 wound around the winding jig 2a by a hot air device (not shown) during winding to melt the fusion layer of the wire 1 and fuse and solidify the wires.

  After the winding of the winding jig 2a is completed, the winding jig moving mechanism 60 and the wire guide moving mechanism 70 are operated in synchronization, thereby retracting the winding jig 2a and the wire guide 50a to their original positions. At this time, the flyer moving mechanism 23 is operated, and the flyer 6 is also moved by the same distance in the same direction as the winding jig 2a. This is because when the flyer 6 is not moved along with the movement of the winding jig 2a, the fused and solidified wire 1 is pulled on the winding jig 2a, and the fused portion of the wire 1 may be peeled off. This is to prevent this.

  Then, by operating the winding jig feeding mechanism 8, the holder 58 is moved in the Y-axis direction, and the winding jig 2b arranged adjacent to the winding jig 2a is opposed to the spindle shaft 3 on the same axis. 6 at the center of rotation. Thereafter, the above-described operation is repeated to perform winding on the winding jig 2b.

  As described above, the winding jigs 2a to 2d are sequentially sent to a position that is coaxial with and opposite to the spindle shaft 3, and the winding jigs 2a to 2d are sequentially wound to connect a plurality of coils. Wind the connected coil.

  After the winding of the winding jigs 2a to 2d is completed, the space between the winding jig 2a and the clamp 80 in the wire 1 is cut. Then, the gap between the winding jig 2d and the nozzle 5 in the wire 1 is held by the clamp 80, and the gap between the winding jig 2d and the clamp 80 is cut. Thereby, the wire 1 wound around the winding jigs 2 a to 2 d is separated from the clamp 80 and the nozzle 5.

  Next, by operating the drive mechanism 65 in the winding jig moving mechanism 60, the winding jigs 2a to 2d are retracted and accommodated in the through holes 78 of the wire guides 50a to 50d. At this time, since the movement of the coils wound around the winding jigs 2a to 2d is restricted by the end surfaces of the wire guides 50a to 50d, the coils are removed from the outer circumferences of the winding jigs 2a to 2d.

  The coil is also removed by operating the wire guide moving mechanism 70 to advance the wire guides 50a to 50d and accommodate the winding jigs 2a to 2d in the through holes 78 of the wire guides 50a to 50d. be able to. That is, the coil is removed by operating at least one of the winding jig moving mechanism 60 and the wire guide moving mechanism 70 and accommodating the winding jigs 2a to 2d in the wire guides 50a to 50d.

  According to the present embodiment described above, the plurality of winding jigs 2 a to 2 d are sequentially sent to positions confronting on the same axis as the spindle shaft 3, and the wire rod 1 turns around the spindle shaft 3. Therefore, the distance between the wound winding jigs 2a to 2d and the nozzle 5 is always kept constant during winding. Therefore, since the tension of the wire 1 is kept constant during winding, it is possible to wind at a higher speed and to perform winding efficiently. Moreover, since the tension | tensile_strength of the wire wound around the winding jigs 2a-2d is constant, it is easy to obtain a desired coil shape.

  Further, since the winding jigs 2a to 2d can be individually moved in the axial direction of the spindle shaft 3, the winding jig to be wound among the plurality of winding jigs 2a to 2d does not interfere with other winding jigs. It can arrange | position to a position and can wind efficiently.

  Since the wire guide 50 is detachably held by the holder 58, the number of winding jigs 2 can be freely set. Therefore, unlike a conventional winding device, it is not necessary to prepare a separate winding device according to the number of connected coils, or to prepare a plurality of spindle shafts. A connecting coil having a desired number of stations can be wound, and the winding of connecting coils having different stations can be flexibly handled.

  Furthermore, in this embodiment, since each member is moved by a motor, various controls of each member can be easily performed. For example, when the interval of the cover member 51 in the holder 58 is changed depending on the dimensions of the coupling coil, the movement distance of the winding jig 2 in the Y-axis direction by the winding jig feeding mechanism 8 and the winding jig It is necessary to control the moving distance of the winding jig 2 in the X-axis direction by the moving mechanism 60. However, since this control can be performed by the holder moving motor 54 and the winding jig moving motor 66, it is very easy.

  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 a connecting coil.
