Description

[Detailed Description of the Invention] The present invention relates to an improvement of a reel for winding wire rod.

BACKGROUND ART Conventionally, a method shown in FIGS. 1 and 2 has been used to wind up a wire rod such as a hard steel wire or steel cord onto a reel and fix the end of the wire rod when the wire rod is fully wound.

However, in the method shown in FIG. 1, the final winding part of the wire rod 2 wound around the reel 1 is folded back to form a folded part 3, and the terminal part 4 of the wire rod 2 is hooked on the folded part 3. Because the wire is bent and the end is fixed, it has the disadvantage that the wire tends to loosen, causing tangles.

In addition, in order to eliminate this drawback, a method shown in FIG. 2 has been considered, but in this method, a small hole 6 is provided in the outer periphery of the flange 5 of the reel 1, and the end portion 4 of the wire rod 2 is inserted into the small hole 6. Since the end is fixed by hooking and bending, it takes time and effort to pass the end 4 of the wire through the small hole 6, making the work complicated and making it difficult to take out the end when disconnecting the wire. be.

Another drawback is that when the reel is rolled and transported, the wire on the outer peripheral edge of the reel flange is cut and detached, causing the wire to unravel.

The present invention has been made to eliminate the above-mentioned drawbacks, and embodiments thereof will be described below with reference to the drawings.

As shown in FIG. 3, the outer periphery of the flange of the reel 1 is bent outward to form the flange outer peripheral edge 7, and a notched groove 8 larger than the diameter of the wire rod 2 is formed in a part of the outer peripheral edge 7. established,
A clip 9 for gripping the end of the wire rod 2 is provided at a folded portion of the outer surface of the reel flange at a position close to the notch groove 8.

The clip 9 is made of hard steel wire and is bent into a substantially U-shape, an oval shape, etc. to form a gripping part for the wire rod 2, and its both leg ends are bent laterally to form a part for attaching to the reel 1. To run away.

Further, the lower end of the clip 9 is bent outward in a dogleg shape to form an insertion portion for the wire rod 2.

The mounting portion of the clip 9 is inserted from the lower end of the outer circumferential folded portion of the reel flange, and the mounting portion is supported and mounted within the outer circumferential folded portion of the reel flange by its elastic force.

Therefore, the clip 9 is attached so that its upper half is always in contact with the outer surface of the reel flange.

In the above structure, it is preferable that the cutout groove 8 is a V-shaped groove to prevent the wire 2 from slipping.

Further, the clip mounting portion 10 may be formed by removing a portion of the outer circumferential folded portion of the reel flange.

In this case, the clip 9 is fitted with the mounting parts at both leg ends of the clip from the clip mounting part 10, and is supported within the outer circumferential folded part of the flange by the elastic force of the mounting parts.
The clip is installed so that the upper half of the clip is always in contact with the outer surface of the flange.

Since the reel of the present invention has the above structure, the end of the wire wound on the reel is inserted between the clip and the reel flange through the notch groove, and is securely clamped and fixed by the elastic force of the clip. Ru.

As described above, the reel of the present invention has an extremely simple structure, so there is no need to bend the end of the wire into the hole provided in the reel flange or tie the wire, making it possible to securely secure the end of the wire with an extremely simple operation. It can be fixed in place, and it is also easy to work when unraveling the wire.

Moreover, even when the reel is rolled, the terminal will not be damaged or disconnected, and since the clip is placed close to the notch, the end of the wire can be inserted easily and reliably, which has its practical value. There is something big.
