Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical cable and an I cable.
The present invention relates to a prefabricated paper drum used for winding lightweight electric wires and cables such as V and OW or tubes and hoses.

[0002]

2. Description of the Related Art Hitherto, electric wires and cables such as optical cables, IVs and OWs, tubes, hoses and the like have been wound on wooden drums or plastic drums. There was a point.

It is difficult to dispose of used drums. Takes place for storage because it is bulky. Being bulky, transportation costs are incurred. It is difficult to reduce costs because it is processed in a drum factory. The drum is heavy.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems described in the prior art, and is easy to dispose after use, occupies a small space for storage, and has a light assembly type. The purpose is to provide paper drums.

[0005]

SUMMARY OF THE INVENTION A prefabricated paper drum according to the present invention is provided with a shaft hole at a central portion, radially spaced from the center of the shaft hole, and radially spaced apart from each other. A U-shaped body plate made of paper material is fitted into the U-shaped through holes of the two flanges made of paper material having a U-shaped through hole, and furthermore, A paper material is wound around the outer periphery of the body plate.

In another assembly type paper drum according to the present invention, a shaft hole is formed in a center portion, and a plurality of radially U-shaped plural holes are spaced apart from the center of the shaft hole in the radial direction. The U-shaped through-hole of two flanges made of paper material having a through-hole formed therein and a U-shaped through-hole, and a shaft hole is formed at the center, and the shaft is radially separated from the center of the shaft hole. Drill a plurality of U-shaped through holes radially at the same interval as
It is made of a paper material provided with a notch at the edge, and is bent into a U-shape made of a paper material into the U-shaped through hole of one middle collar disposed between the two flanges. A body plate is fitted, and a paper material is further wound around the outer periphery of the body plate.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, an embodiment of the invention according to claim 1 will be described with reference to the drawings. As shown in FIGS. A shaft hole 1 is formed in the shaft portion, and the shaft hole 1 is radially separated from the center of the shaft hole 1, and is made of a paper material such as a step ball having four through holes 2 radially formed at intervals. .

The body plate B bent in a U-shape is shown in FIG.
(A) is formed as shown in the figure, and can be fitted in the U-shaped through hole 2 of the flange A, and is provided with a notch 5 that can be fitted into the flange A at a bent portion inside from both ends. -It is made of paper such as paper.

When assembling two flanges A and the body plate B, as shown in FIG. 3, the U-shaped body plate B is inserted into the U-shaped through hole 2 of the flange A, and Body B folded in the shape of
Is fitted into the U-shaped through hole 2 of the flange A. Since the body plate B is formed in a U-shape, the inward bending of the body plate B can be prevented when a product such as a cable is wound.

Next, as shown in FIG. 4, a paper material 3 such as a step ball or kraft paper is wound around the outer periphery of a U-shaped body plate B. By winding the paper material 3, the U-shaped body plate B is firmly fitted into the U-shaped through hole 2 of the flange A,
A robust drum can be finished.

An embodiment of the invention according to claim 2 will be described with reference to the drawings.
As shown in FIG. 5, the middle collar C has a shaft hole 1 ′ in the center.
And radially spaced from the center of the shaft hole 1 ′ to form four U-shaped through-holes 2 ′ radially at the same interval as the interval between the flanges A. Notch 4 in part
Made of a paper material such as a corrugated ball.

[0012] As shown in Figs.
It is arranged so as to be located between the two flanges A.

The body plate B ′ bent in a U-shape is shown in FIG.
(B), it can be fitted into the U-shaped through-hole 2 of the flange A and the U-shaped through-hole 2 'of the middle flange C, and has bent portions inside from both ends. Further, it is made of a paper material such as a corrugated ball provided with notches 5, 5 'which can be fitted in the collar A and the middle collar C.

When assembling the collar A, the middle collar C and the body plate B ′, as shown in FIG. 6, the U-shaped body plate B ′ is formed by passing the flange A and the middle collar C in a U-shape. The notch 5 of the body plate B 'is inserted into the U-shaped through hole 2 of the flange A, and the body plate B'
Is inserted into the U-shaped through hole 2 ′ of the middle flange C.

Next, as shown in FIG. 7, a paper material 3 such as a step ball or kraft paper is wound around the outer periphery of the U-shaped body plate B '. By winding the paper 3, the body plate B ′ is firmly fitted into the U-shaped through holes 2 and 2 ′ of the flange A and the middle flange C, so that a robust drum can be finished.

The drum assembled as shown in FIG. 7 has, for example, an optical cable or a tube wound in a space formed by a left collar A and a middle collar C in a few turns. Through the notch 4 of the middle flange C, the remaining optical cable or tube is wound around the space formed by the middle flange C and the right flange A.

In this way, when laying the cables and tubes while rewinding them from the drum, new cables and tubes and the like are sequentially connected to the winding start end. Therefore, there is an advantage that the laying work can be performed efficiently. The number of the U-shaped through holes 2, 2 'is not limited, and can be freely increased or decreased as needed. There is no particular limitation on the paper material.

The flange A, the middle collar C, and the body plate B may be finished with one sheet of paper, or may be finished with a plurality of sheets of paper, depending on the strength of the paper used. Good.

[0019]

As described above, the present invention has the following advantages. Disposal of the used drum is easy. It is not bulky and does not take up space for storage. Since it is not bulky, transportation costs can be saved. Since mass production can be performed at the paper processing plant, costs can be reduced. The drum is light.
