[Industrial applications]

 The present invention relates to a coil winding machine for automatically winding a wire around a coil bobbin.

[0002]

[Prior art]

 Conventionally, a coil winding machine that automatically winds a wire around a set coil bobbin is known.

FIG. 4 shows a typical conventional coil winding machine 50. In the figure, reference numeral 51 denotes a machine body, and a front outer surface portion thereof is provided with a winding portion 52 and a wire guide portion 53. The winding section 52 has a bobbin setting section 55 for setting the coil bobbin Bo, and the bobbin set section 55 is rotated by a drive section incorporated in the machine body 51. Reference numeral 56 is a flywheel provided in the bobbin setting section 55. On the other hand, the wire guide portion 53 has a support shaft portion 57, and the support shaft portion 57 is repeatedly displaced in the axial direction of the winding portion 52 by a drive portion incorporated in the machine body 51. Then, the guide unit portion 58 is supported by the support shaft portion 57. The guide unit portion 58 includes a support arm portion 59. The mounting portion 60 provided at one end of the support arm portion 59 is fixed to the support shaft portion 57 with a screw, and the other end of the support arm portion 59 is provided with a first arm. A guide portion main body 63 having one guide pulley 61 and a second guide pulley 62 is provided. Reference numeral 64 is an adjusting unit for adjusting the axial position of the guide unit body 63.

Therefore, the coil bobbin Bo is set in the bobbin setting section 55, and the wire Wo supplied from a wire supply section (not shown) is bridged in the order of the first guide pulley 61 and the second guide pulley 62. When the coil winding machine 50 is operated after being fixed to the coil bobbin Bo, the winding section 52 rotates the bobbin setting section 55, the wire Wo is wound around the coil bobbin Bo, and the wire guide section 53 moves the wire Wo. Since the guide position is repeatedly displaced in the axial direction of the winding section 52, the wire Wo is sequentially wound in layers along the winding width of the coil bobbin Bo.

[0005]

[Problems to be solved by the device]

 However, such a conventional coil winding machine 50 is limited to one coil that can be manufactured at the same time. Therefore, when manufacturing a plurality of coils by simultaneously winding a plurality of coils on a plurality of coil bobbins, Since it was necessary to prepare multiple machines, there were problems that the installation space increased, workability deteriorated, and the cost increased significantly. There are coil winding machines that can manufacture multiple coils at the same time, but on the other hand, if only one coil is manufactured at the same time, unnecessary costs will be imposed.

The present invention solves the problems existing in such conventional techniques, and saves space, improves workability and mass productivity, significantly reduces cost, and improves usability. It is an object of the present invention to provide a coil winding machine that can be designed.

[0007]

The auxiliary wire guide portion 4s is provided.

In this case, the auxiliary winding section 2s can be configured to include a support section 6 attached to the outer surface section Mp of the machine body M, and a winding section body 7 rotatably supported by the support section 6. Further, the rotation transmission mechanism section 5 includes a driven pulley 8 provided on the winding section main body 7, a driving pulley 9 provided on the main winding section 2m, and a transmission belt 10 spanned between the driven pulley 8 and the driving pulley 9. Can be configured. The axial position of the auxiliary winding section 2s for setting the coil bobbin Bs is preferably offset by a predetermined width H from the axial position of the main winding section 2m for setting the coil bobbin Bm.

On the other hand, the main wire guide portion 4m can be configured to include a support shaft portion 11 that is repeatedly displaced in the axial direction of the main winding portion 2m, and a main guide unit portion 12 attached to the support shaft portion 11. The auxiliary wire guide portion 4s includes an auxiliary guide unit portion 13, and the auxiliary guide unit portion 13 can be attached to the support shaft portion 11. The guide position of the wire Ws in the displacement direction of the auxiliary wire guide portion 4s is preferably offset by a predetermined width H from the guide position of the wire Wm in the main wire guide portion 4m.

[0010]

[Action]

 According to the coil winding machine 1 according to the present invention, originally, a single winding type coil winding machine in which the wire Wm is wound around one coil bobbin Bm is provided with one (or two or more) auxiliary winding portions 2s. A multi-winding coil winding machine for simultaneously winding the wires Wm, Ws on the plurality of coil bobbins Bm, Bs by attaching one (or two or more) auxiliary wire guide portions 4s by a retrofit method. Can be easily changed to. Therefore, the aircraft M is used in common.

As a result, when the main winding section 2m rotates, the wire Wm is wound around the coil bobbin Bm set in the main winding section 2m. The rotation of the main winding section 2m is transmitted to the auxiliary winding section 2s via the rotation transmission mechanism section 5. That is, the drive pulley 9 is rotated by the rotation of the main winding portion 2m, and this rotation is transmitted to the driven pulley 8 via the transmission belt 10. The auxiliary winding section 2s is rotated by the rotation of the driven pulley 8, and the wire Ws is wound around the coil bobbin Bs set in the auxiliary winding section 2s. In this case, by making the drive pulley 9 and the driven pulley 8 have the same diameter, the auxiliary winding section 2s and the main winding section 2m rotate at the same speed.

On the other hand, since the main wire guide portion 4m is repeatedly displaced in the axial direction of the main winding portion 2m, the guide position of the wire Wm is also repeatedly displaced integrally, and the wire Wm is sequentially arranged along the winding width of the coil bobbin Bm. It is wound repeatedly. Further, since the auxiliary wire guide portion 4s also shares the support shaft portion 11 in the main wire guide portion 4m, the auxiliary wire guide portion 4s is displaced integrally with the main wire guide portion 4m. Therefore, the guide position of the wire Ws is also repeatedly displaced, and the wire Ws is sequentially wound in layers along the winding width of the coil bobbin Bs.

The axial position where the coil bobbin Bs is set in the auxiliary winding section 2s is offset by a predetermined width H from the axial position where the coil bobbin Bm is set in the main winding section 2m, and the auxiliary position is set. If the guide position of the wire Ws in the displacement direction of the wire guide portion 4s is offset from the guide position of the wire Wm in the main wire guide portion 4m by a predetermined width H, the wire on the main winding portion 2m side is offset. Since Wm and the wire Ws on the side of the auxiliary winding section 2s are separated from each other by a predetermined width H in the axial direction, mutual independence (non-interference) and workability are secured.
