DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper bobbin capable of winding a wire such as an optical fiber cable and a coaxial cable around its body.

[0002]

2. Description of the Related Art In recent years, in the case of telephone lines and other communication lines, optical fiber cables and coaxial cables have been increasingly used in place of conventional copper cables. This is because these cables have larger information capacity and lower loss. Further, such an optical fiber or coaxial cable has an advantage that it is lightweight and easy to handle as compared with a copper wire.
Conventionally, such a cable is wound around the body of a wooden bobbin 1 (see FIG. 8) used for winding a high-voltage electric wire, and is housed, for example, transported to a construction site or stored in a warehouse. Further, the wooden bobbin 1 transported to the construction site had the shaft 3 inserted through the central shaft hole 2 and supported by the gantry 4 (see FIG. 9). Then, the entire bobbin 1 is turned in the direction of arrow A, and the wound optical fiber 5 is sent out into the manhole 6.

[0003]

However, the wooden bobbin 1 has a certain degree of strength but is very heavy, and it is difficult to handle the wooden bobbin 1 alone because it weighs more than 30 kg. In particular, they were rolled and moved on construction sites, and forklifts were used to load and unload trucks. Further wooden bobbins 1
In the case where the wound cable is exported to other countries, the fumigation process is required during the quarantine procedure because the bobbin part is made of wood, which alone requires extra cost and time. And it was.

Further, since such a wooden bobbin 1 is bulky after use and uses a lot of nails and metal fittings even if it is incinerated, the wooden part and the metal fittings must be separated after being once disassembled. (For reasons of protecting the incinerator). However, such disassembly work is very costly and time-consuming, so it has been sent to a specific waste disposal company.

[0005] Under these circumstances, the applicant is considered to be suitable for winding optical fiber cables, coaxial cables, and the like, which are relatively lighter than high-voltage electric wires and the like, and has a certain strength that is easy to disassemble and easy to incinerate. The development of a paper bobbin with However, even if it is a bobbin made of paper, it can be disassembled by simply increasing the size of a conventional bobbin that winds a wrapping strap (one that has disk paper on both sides of a tubular body). However, when it is rolled on a construction site or used by being supported on a gantry 4 as shown in FIG. 9, the strength is insufficient.

The present invention has been made in view of the above points, and an object of the present invention is to provide a bobbin made of paper which can be easily assembled and disassembled and which can be completely incinerated.
