Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a paper reel suitable for winding a cable such as a power line or a telephone line or a wire such as a wire or a chain.
[0002]
[Prior art]
Conventionally, a reel made of a synthetic resin or a wooden reel has been used as a reel around which a relatively heavy wire such as a cable, a wire, or a chain as described above is wound. The reel is configured by integrally attaching flanges to both ends of the winding drum, and winding the wound material on the outer peripheral surface of the winding drum, and the end portions of the wound material wound by the flanges at both ends. Protected and rolled.
[0003]
The former synthetic resin reel is suitable for mass production because it is made by molding, but it has the advantage of beautiful appearance, but the mold cost and material cost increase, and when it is incinerated as industrial waste after use. However, since harmful substances are contained in the exhaust gas discharged from the incinerator, there is a problem that the environment around the incinerator is polluted. In particular, due to various unfavorable social problems associated with waste disposal in recent years, there has been a problem that recycling is not possible despite the fact that recycling is desired.
[0004]
The latter wooden reels are heavy and inconvenient, and have the convenience of being incinerated when they are no longer needed.However, since many metal fittings such as nails are used, they must be separated from the metal fittings before incineration. And a lot of trouble and time had to be spent on the work. In addition, there is a problem that it is not suitable from the viewpoint of depletion of timber resources, soaring timber prices and protection of the global environment.
[0005]
As a solution to these drawbacks, it is light, easy to handle, and inexpensive, and if it is no longer needed, it can be reused as waste paper for recycling, such as paperboard, and does not cause pollution problems as industrial waste. A paper reel comprising a paper tube and cardboard has been proposed. (For example, see Patent Document 1.2)

[0007]
[Problems to be solved by the invention]
However, the paper reels made of the paper tube and cardboard disclosed in the above-mentioned Patent Documents 1 and 2 include a winding drum outer cylinder, a flange body engraved with radial cuts, and the flange body disposed on both sides of the winding drum outer cylinder. It consists of an inner tube for crimping to be attached.When winding heavy wires such as cables such as power lines and telephone lines or wires and chains, a large winding pressure is applied to the winding drum and it can withstand the heavy load. However, it could not be used because it was bent and could not be accurately wound, or the bonding portion between the winding drum and the collar body was peeled off and crushed.
[0008]
Further, when the reel is rolled and moved at the time of storage at a construction site or a warehouse, for example, the flange to be grounded is weak and may be broken or damaged. Furthermore, when the diameter of the winding drum is increased so as not to give a curl to the wound material, the diameter of the inner cylinder for crimping increases, and the difference between the inner diameter and the outer diameter cannot necessarily be increased. Therefore, if the shaft center is not strengthened, it will be weakened, but the means has not been applied. For example, when the shaft is inserted through the center shaft hole, and the wound material is wound and unwound by pressing with a clip from the outer surface of the flange body, it can withstand the surface pressure from the left and right directions of the flange body. However, there has been a problem that accurate winding cannot be performed, such as occurrence of friction slip or damage to a flange portion, resulting in poor winding or unwinding.
[0009]
The present invention has been developed with the object of solving the above problems, and the winding drum portion and the shaft portion have a triple structure, and the whole is made of paper but has sufficient strength, It can wind up heavy loads such as cables, wires, chains, etc., and also strengthens against external force in the axial direction (length direction), preventing damage and breakage, and is easy to assemble and manufacture. It is an object of the present invention to provide a useful paper reel which can be reused as recycled waste paper when it is no longer needed and which is useful for resource conservation.

We developed and adopted a paper reel characterized in that the winding drum unit and the shaft unit, which were bonded between the inner tube and the inner tube, each had a triple structure.
[0011]
Further, in the present invention, in the paper reel configured as described above, the flanges attached to both sides of the winding paper core have a large diameter, the flanges attached to both sides of the shaft paper core have a small diameter, A paper reel in which the outer peripheral surface of the body is bonded to the folded piece of the winding paper tube, and the inner surface of the outer periphery is bonded and integrated with the end of the inner cylindrical paper tube of the winding paper tube, and a paper reel of the winding paper tube.
