DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for fixing an end of a wire used for an end treatment after winding an ultrafine wire made of, for example, a metal material on a bobbin.

[0002]

2. Description of the Related Art Conventionally, as a method of fixing the end of a wire of this type, there is known a method in which the end of the wire is locked in a locking groove formed in a bobbin flange when the bobbin is fully wound. Have been.

[0003]

However, in the case of the above-mentioned conventional structure, the wire rod W may be cut because the terminal end portion is locked in the locking groove of the bobbin flange, and the process is complicated, so that the automation is difficult. Is a major bottleneck.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to solve such a problem. The gist of the present invention is to wind a wire rod sequentially fed out onto a rotating bobbin, and set the bobbin in a fully wound state. In the method of fixing the end portion of the wire wound around the bobbin, a wrapping sheet is interposed between the wire reaching the bobbin and a full winding surface of the wire, and the wrapping sheet is filled with the wire by rotation of the bobbin. A wire is wound around the surface of the packaging sheet material while being wound on the winding surface, and an adhesive sealing material is applied to the overlapped portion of the packaging sheet material in a state where the rear edge of the packaging sheet material is superimposed on the leading edge of the packaging sheet material. And fixing the end portion of the wire by attaching the end portion of the wire including the end portion of the wire.

The above-mentioned packaging sheet material can be made of rust-proof paper, and the adhesive sealing material can be made of an adhesive label.

[0006]

[Function] A packaging sheet is interposed between a wire reaching a bobbin and a full winding surface of the wire, and the bobbin is rotated so that the packaging sheet is wound on the full winding surface of the wire and the wire is wound on the surface of the packaging sheet. The adhesive sealant is attached to the overlapped portion of the packaging sheet material including the terminal end portion of the wire material in a state where the rear edge of the packaging sheet material is superimposed on the leading edge portion of the packaging sheet material. The final terminal part will be fixed.

[0007]

1 to 8 show an embodiment of the present invention. Reference numeral 1 denotes a bobbin, which is mounted on a winding shaft 2 which is wound and rotated by a drive mechanism (not shown), and is provided on a side of the bobbin 1. Is arranged so that the wire W is wound around the bobbin 1 by cooperation of reciprocation of the guide 3 and rotation of the bobbin. In addition, the position of the guide 3 is fixed,
The bobbin 1 may be reciprocated in the axial direction and wound up.

Reference numeral 4 denotes a wrapping sheet material, which is made of rust-proof paper and has a width substantially equal to the inner dimension of the bobbin flanges 1a on both right and left sides of the bobbin 1. The packaging sheet material 4 may be a so-called sheet, or may be cut into a predetermined size using continuous paper.

Reference numeral 5 denotes an adhesive sealing material. In this case, an adhesive label having one surface formed on an adhesive surface and having a product name and contents printed thereon is used.

In the above embodiment, when the wire W is wound around the bobbin 1 and becomes full as shown in FIG.
As shown in FIG. 5, the wire W reaching the bobbin 1 and the full winding surface M of the wire W
As shown in FIG. 7, the packaging sheet material 4 is wound around the full surface M of the wire material W by the rotation of the bobbin 1 as shown in FIG. W is wound, and as shown in FIG. 8, the rear end edge 4b of the packaging sheet material 4 is superimposed on the front edge 4a of the packaging sheet material 4, and in this superimposed state, the packaging sheet 4 is folded as shown in FIGS. The adhesive sealing material 5 is applied to the overlapped portion of the material 4 with the end portion S of the wire W.
The end of the wire W is cut off after the application, so that the end S of the wire W is fixed as shown in FIG.

Accordingly, the wrapping sheet material 4 is wound between the wire W reaching the bobbin 1 and the full winding surface M of the wire W, and the wire W is wound around the surface of the wrapping sheet material 4. In a state where the portion 4a and the rear edge 4b overlap, the end sealing portion 5 of the wire W can be fixed by attaching the adhesive sealing material 5 including the end portion S of the wire W. Can fix the end portion S of the wire W, and also can fix the wrapping sheet material 4 at the same time, and these can be easily automated. When the wire W is unwound from the bobbin W, Adhesive sheet material 5
Can be performed only by peeling or tearing, and the work efficiency can be improved.

The wrapping sheet material 4 can be made of rust-proof paper to suppress the generation of rust on the wire W, and the adhesive seal material 5 can be made of an adhesive label to indicate the product name and quality. be able to.

It should be noted that the present invention is not limited to the structure shown in the above embodiment, but includes the packaging sheet material 4 and the adhesive sealing material 5.
The material, size, etc. are designed as appropriate.

[0014]

As described above, the present invention interposes and winds a wrapping sheet between a wire reaching a bobbin and a full winding surface of the wire and winds the wire on the surface of the wrapping sheet. In a state where the leading edge and the trailing edge are overlapped, the terminal end of the wire can be fixed by sticking the adhesive sealing material including the terminal end of the wire, so that the end of the wire W can be easily fixed. The terminal part can be fixed, the packaging sheet material can be fixed at the same time, and these can be easily automated.When unwinding the wire from the bobbin, just peel or tear off the adhesive sheet material And work efficiency can be improved.

As described above, the intended purpose can be sufficiently achieved.
