【Example】

 The details of the present invention will be described with reference to further illustrated embodiments. As shown in FIG. 1, a flat wire winding bobbin A according to a typical embodiment of the present invention comprises a shaft core 1, a collar portion 2, and a twist-preventing wire escape portion 3. A winding body B is formed by winding the rectangular wire S around the rectangular wire winding bobbin A. Furthermore, what is applied to the terminal end of the rectangular wire S in this winding body B is the end portion processing structure C of the winding body B as shown in FIG.

As shown in FIG. 2, the rectangular wire winding bobbin A has disk-shaped collar portions 2 provided on both sides of a hollow shaft core 1 and the hollow portion of the shaft core 1 is used as a mounting hole 4. A wire escape portion 3 for preventing twisting when the rectangular wire S is wound is provided on the inner surface of one of the collar portions 2. In particular, this bobbin A is intended to wind a rectangular wire S used for internal wiring of, for example, a video cassette recorder or a robot.

The twisting prevention wire escape portion 3 is for locating the starting end portion 6 of the rectangular wire S and letting it escape to the outside from the inner surface of the collar portion 2, that is, a bottomed groove portion as shown in FIG. The groove portion 5 expands in the tangential direction to the surface of the shaft core 1 toward the outer peripheral end of the collar portion 2, and the front side 5a in the rotation direction of the groove portion 5 is set to a helix so that the rectangular wire S is not scratched. The tip portion 5b of the groove portion 5 is rounded, and the depth of the groove portion 5 is set to be slightly larger than the plane width of the rectangular wire S. By providing the twist-preventing wire escape portion 3 in this manner, the twist of the rectangular wire S between the shaft core 1 of the bobbin A and a guide member described later can be eliminated.

The wire escape portion 3 may have various other shapes. For example, as shown in FIG. 4, a groove portion 5 having a constant width is formed from the outer peripheral end of the collar portion 2 toward the center of the shaft core 1. It may be provided, or a groove portion 5 having a constant width may be provided tangentially to the surface of the shaft core 1 as shown in FIG. 5, or 1/4 of the inner surface of the collar portion 2 may be formed as a groove portion 5 as shown in FIG. It may be one that you have done. Further, although the wire escape portion 3 uses a grooved portion having a bottom, it may have a groove having a similar shape and penetrated inside and outside the collar portion 2.

Next, in the winding body B, the bobbin A is used to position the starting end 6 of the rectangular wire S in the wire escape portion 3 as shown in FIG. The rectangular wire S is wound in a substantially flat state on the shaft core 1 in a state of being released to the outside, and the rectangular wire S is wound in multiple layers. Further, the winding body B may be one in which the end portion processing structure C of the winding body B described below is applied.

The end treatment structure C of the winding body B has a structure in which a rectangular wire S is wound around a bobbin A as shown in FIG. 7, and a holding sheet 8 is positioned at the winding terminal end 7 to form the rectangular wire S. The terminal end portion 7 of S is wound at least once, and the terminal end portion 7 of the rectangular wire S is fixed by a tape 9 such as an adhesive tape. Particularly, in the case of the example shown in the drawing, the end portion 7 of the rectangular wire S is wound once, the terminal end 7'of the rectangular wire S is positioned on the holding sheet 8, and the terminal end 7'of the rectangular wire S 1 is used as a free end. Both of the remaining end portion 7 and the once wound rectangular wire S or only the slightly left end portion 7 which is not shown is fixed to the sheet 8 with the tape 9. The holding sheet 8 is a sheet made of synthetic resin, paper, or the like, and is compatible with various sizes and materials of the rectangular wire S shown on the label 10 attached to the surface of the collar portion 2. It is a colored one. In addition, a label 10 colored in a color corresponding to the size and material of the rectangular wire S is attached to the surface of the collar 2 of the rectangular wire winding bobbin A, and the same color is colored on the holding sheet 8. It can also be used. Further, in addition to coloring the holding sheet 8, characters, symbols, etc. representing the size, material, etc. of the rectangular wire S can be expressed.

Then, as shown in FIG. 2, the mounting hole 4 of the bobbin A is externally fitted to the mounting rod 14 which is erected on the base 12 of the winding device 11 for the rectangular wire S and has the screw portion 13 at the tip. Then, the bobbin A can be attached to the winding device 11 by screwing the nut 15 into the screw portion 13, and further, as shown in FIG. 1, a plate in which the starting end portion 6 of the rectangular wire S is provided on the base 12. While guiding through the body 16 and the guide member 18 and locating the starting end 6 of the rectangular wire S inside the wire rod escape portion 3 on the inner surface of the collar portion 2 and allowing it to escape outside the inner surface of the collar portion 2, By rotating the base 12 of the winding device 11 in the direction of the arrow in the drawing and moving the rectangular wire S in the arrow direction in order, the rectangular wire S can be wound in a substantially flat state on the shaft core 1. Then, at the winding end portion 7, the holding sheet 8 is positioned as shown in FIG. 7, the end portion 7 of the rectangular wire S is wound once, and the end 7 ′ of the rectangular wire S is held. Both of the end portion 7 and the once wound rectangular wire S are fastened with the tape 9 while being positioned on the sheet 8 and leaving the terminal end 7 ′ of the rectangular wire S as a free end.

As described above, according to the bobbin A and the winding body B of the representative embodiment according to the present invention, the starting end portion 6 of the rectangular wire S is located in the wire rod escape portion 3 on the inner surface of the collar portion 2. Since the rectangular wire S is wound around the bobbin A in a state in which the rectangular wire S is released from the inner surface of the portion 2, the rectangular wire S hits the inner surface of the collar portion 2 and is wound in a twisted state, or the adjacent rectangular wire S is wound. Since the side ends are not wound in a state of being overlapped with each other, the winding flat wire S of the bottom bottom is not twisted because the entire shaft core 1 of the bobbin A, especially the winding start end portion, is not twisted. Thus, the height of the wound rectangular wire S can be made constant, the rectangular wire S can be evenly wound, and the surface of the rectangular wire S is not scratched. Further, since the groove portion 5 is provided in the tangential direction with the surface of the shaft core 1 in the twist preventing wire rod escape portion 3 shown in FIG. 3, the start end portion 6 of the rectangular wire S is surely moved along the trajectory of the rectangular wire S. Can be escaped to the outside of the inner surface of the collar portion 2, and further expands toward the outer peripheral end of the collar portion 2, so it is easy to guide the rectangular wire S from the outer peripheral end of the collar portion 2 toward the axis 1. Since the front side 5a of the groove portion 5 in the rotating direction is set to be a die, the position at which the rectangular wire S starts to be wound around the shaft core 1 can be kept constant without variation, and the tip portion 5b of the groove portion 5 can be further fixed. Since the rectangular wire S is rounded, the rectangular wire S is not damaged even if the rectangular wire S contacts the tip 5b of the groove 5, and the depth of the groove 5 is smaller than the flat width of the rectangular wire S. Since it is set to a slightly large size, even if the rectangular wire S shakes slightly during winding, it may come into contact with the inner surface of the collar 2 and cause damage. No.

Further, according to the end treatment structure C of the winding body B of the representative embodiment of the present invention, the terminal end 7 ′ of the rectangular wire S is always positioned on the holding sheet 8 and fixed. Therefore, when using the flat wire S of the winding wire B, the end 7 ′ of the flat wire S can be easily found and the winding of the flat wire S can be unwound. Even in the case of storage at 1, it can be easily attached by simply fixing it on the holding sheet 8 using the tape 9. Further, according to the end portion processing structure C of FIG. 7, since both the end portion 7 of the rectangular wire S left as a free end and the rectangular wire S wound once are fixed by the tape 9, The flat wire S can be securely attached without coming off the shaft core 1 of the bobbin A, and at the time of use, simply pulling the end 7 of the remaining flat wire S is easier than the bobbin A holding sheet 8. The rectangular wire S can be removed. Further, even if the collars 2 of a large number of bobbins A are placed so as to come into contact with each other, the size of the rectangular wire S shown on the label 10 attached to the surface of the collar 2 on the holding sheet 8, Since the characters, symbols or colors corresponding to the material etc. are shown, it is possible to judge the dimension, material etc. of the rectangular wire S by the holding sheet 8, especially the dimension, material etc. of the rectangular wire S by the color. If the holding sheet 8 is colored separately, the size and material of the rectangular wire S can be determined at a glance. Moreover, a label 10 colored in a color corresponding to the size and material of the rectangular wire S is attached to the surface of the collar portion 2 of the rectangular wire winding bobbin A, and the same color is applied to the holding sheet 8 to be used. For example, the size, material, etc. of the rectangular wire S can be determined by the label 10 and the holding sheet 8. Therefore, when a large number of winding bodies B are mounted, the mounting arrangement is not limited.

[Effect of device]

 As described above, according to the flat wire winding bobbin and the winding body of the present invention, the starting end of the flat wire is located inside the wire escape portion on the inner surface of the flange portion and is released outward from the inner surface of the collar portion. Since the rectangular wire is wound on the bobbin, the rectangular wire does not hit the inner surface of the collar and is twisted, or the adjacent ends of the rectangular wire do not overlap. Since the winding flat wire at the bottom of the bobbin is not twisted at the entire winding center of the bobbin, especially at the winding start end, the height of the flat wire wound in such a way can be made constant, and the flat wire can be evenly wound. The wire can be wound and the surface of the rectangular wire is not scratched.

Further, since the groove portion is provided in the twisting prevention wire rod relief portion in the tangential direction to the surface of the shaft core, the start end portion of the flatness wire is surely escaped to the outside from the inner surface of the collar portion along the trajectory of the flatness wire. Moreover, since the depth of the groove is set to be slightly larger than the flat width of the rectangular wire, even if the rectangular wire is slightly shaken during winding, it will not come into contact with the inner surface of the flange and be damaged.

Further, if it is enlarged toward the outer peripheral end of the flange, it becomes easy to guide the starting end of the rectangular wire toward the axis.

Further, if the front side of the groove portion in the rotation direction is set to be a die, the position where the rectangular wire starts to be wound around the shaft center can be kept constant without variation.

Further, by rounding the tip of the groove, even if the rectangular wire comes into contact, it will not be damaged.
