【Example】

 One embodiment of the present invention will be described in detail below with reference to the drawings. The drawings show a paper winding reel used when winding an electric wire which is an example of a long object. In FIGS. 1 and 2, the paper winding reel 10 has a reel body 11 A core 20 having a hollow cylindrical shape for winding the flexible electric wire A, and a substantially disk-shaped side plate 30 for regulating the electric wire A on the core 20. The wire A is formed of a paper material (for example, cardboard or corrugated paper) having a thickness and strength necessary for winding the wire A.

The above-described core 20 is formed to have a length and an outer diameter where the long electric wire A is continuously wound by a predetermined length, and has a substantially cylindrical insertion portion formed at both ends of the core 20. 21 has an outer diameter substantially the same as or smaller than the hole 31 of the side plate 30, and has a size and shape substantially matching the hole 31. Further, the outer peripheral surface of the core 20 may be formed in a tapered shape having a large diameter from one end to the other end.

The notch 22 formed on the side peripheral surface of the insertion portion 21 is formed continuously in the axial direction from the leading end of the insertion portion 21 toward the base end. When deformed or expanded in the direction (radial direction) locked against the edge 31a of the hole 31 against the material elasticity, the hole 31 is formed to have a length and width that allow the deformation or expansion. . Further, a plurality of notches 22 may be formed at predetermined intervals in the circumferential direction along the side peripheral surface of the insertion portion 21.

The annular step portion 23 formed on the base end side shaft peripheral surface of the insertion portion 21 is formed to have a larger diameter than the hole portion 31, and abuts against the edge 31 a of the hole portion 31. Instead of the core 20, a solid cylindrical core, for example, may be used.

The above-mentioned side plate 30 is formed to have a thickness and an outer diameter for restricting the electric wire A on the winding core 20, and a hole 31 formed at a substantially central portion of the side plate 30 is allowed to be inserted by the above-mentioned insertion portion 21. Hole diameter and round shape. In addition, the wire A is formed in a size and a shape to support the wire A in accordance with the winding amount of the wire A wound on the core 20.

When assembling the winding reel 10 described above, the insertion part 21 on one end side of the winding core 20 is inserted into a hole 31 formed in one of the side plates 30, and then protrudes outward from the hole 31. The inserted portion 21 is deformed and expanded in the radial direction from the inside to the outside, and the folded portion 21a of the inserted portion 21 is locked to the edge 31a of the hole 31 to prevent the insertion.

In addition, an appropriate amount of a paper adhesive B is uniformly applied between opposing surfaces of the folded portion 21 a of the insertion portion 21 and the edge 31 a of the hole portion 31, and the two are integrally adhered and fixed to each other. .

In the same manner as described above, the other end side insertion portion 21 of the core 20 is inserted into the hole 31 formed on the other side plate 31 to prevent the insertion, and the folded portion 21 a of the insertion portion 21 The edge 31a of the portion 31 is integrally bonded and fixed with the adhesive B.

As shown in FIG. 3, after the above-described winding core 20 and side plates 30 and 30 are integrally assembled to assemble one winding reel 10, a long electric wire A is placed on the winding core 20. The winding is regulated on the winding core 20 by the side plates 30 fixed to both ends.

As described above, since the winding core 20 and the side plate 30 constituting the winding reel 10 are formed of a paper material, the work and the process of separating the material by the material are omitted, and the winding reel 10 is manufactured. Almost the whole can be recycled. In addition, since the paper resources can be effectively used, it is possible to improve the recycling efficiency and reduce the recycling cost.

Moreover, the insertion portion 21 of the core 20 is inserted into the hole 31 of the side plate 30 to prevent the insertion, and the folded portion 21a of the insertion portion 21 and the edge 31a of the hole 31 are bonded with an adhesive. B is used to integrally bond and fix, so that rattling is unlikely to occur, and it is possible to fix the shafts so that their axes are substantially aligned. In addition, there is no need to use retaining parts or to form insertion holes, making assembly work easy and the structure is simple. can do.

Further, since the insertion portion 21 of the core 20 is deformed or expanded so as to be engaged with the hole 31 of the side plate 30 and is prevented from being removed, the core 20 and the side plate 30 are firmly fixed. Thus, the strength necessary for winding the electric wire A can be obtained.

FIGS. 4 and 5 show another method of fixing the winding reel 10 in which the insertion portion 21 of the winding core 20 and the hole 31 of the side plate 30 are fitted. Is surrounded by an outer core 25 having a diameter larger than that of the inner core 24, and is supported or loosely fitted with a mutually opposed peripheral surface at a predetermined interval to form a double structure. I have.

On the side plate 30, an annular convex portion 27 is formed along the edge 31 a of the hole 31 so as to face the annular concave portion 26 formed between the opposing peripheral surfaces of the inner core 24 and the outer core 25. doing. Further, the convex portion 27 may be formed partially (for example, in an arc shape) with respect to the edge portion 31a.

At the time of assembling, the concave portion 26 and the convex portion 27 are fitted to each other, and the axis of the insertion portion 21 of the core 20 and the hole 31 of the side plate 31 are regulated to be substantially aligned. In addition to being able to firmly fix each other, alignment and positioning can be performed accurately.

The insertion portions 21 formed at both ends of the inner core 24 are bonded and fixed to the hole 31 of the side plate 30 in the same manner as described above, and the end 25 a of the outer core 25 is Since it is adhesively fixed to the portion 31a, it is possible to obtain substantially the same operation and effect as the above-described embodiment.

As another method of fixing the core 20 and the side plate 30 to each other, for example, as shown in FIG. 6, an annular convex portion 25 b formed at the end of the outer core 25 is formed into an annular shape formed around the hole 31. The opposing portions may be bonded and fixed to each other by being fitted into the concave portion 31b, so that substantially the same operation and effect as in the above-described embodiment can be obtained. In addition, the convex portion 25b and the concave portion 31b may be formed partially.

As shown in FIG. 7, the inner peripheral surface and / or the outer peripheral surface of the convex portion 27 may be formed in a tapered shape in which the diameter gradually increases from the inner end to the outer end. At the time of assembling, even if the axes of the insertion portion 21 and the hole portion 31 are slightly displaced, they are fitted and guided along the tapered surface of the convex portion 27, so that insertion and alignment can be easily performed. .

Further, as another fixing method, as shown in FIG. 8, an end of the hollow or solid formed shaft core 20 is fitted to a substantially circular convex portion 28 formed substantially at the center of the side plate 30. As shown in FIG. 9, the notch 31c formed in the edge 31a of the hole 31 of the side plate 30 is expanded so that the edge 31a of the hole 31 extends inward. After the folding, the end of the shaft core 20 may be fitted to the folded edge 31a of the hole 31 and fixed by bonding, so that substantially the same operation and effect as in the above-described embodiment can be obtained.

In the correspondence between the configuration of the present invention and the above-described embodiment, a long object of the present invention corresponds to the electric wire A of the embodiment, and similarly, the concave portion corresponds to the concave portion 31b, and the convex portion The portions correspond to the insertion portion 21, the protrusions 25b, 27, 28, and the folded edge 31a, but the present invention is not limited to the configuration of the above-described embodiment.

The above-described core 20 and side plate 30 may be formed in an external shape such as an ellipse, a square, a pentagon, and a hexagon.
