Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a winding device made of paper such as cardboard for winding linear objects such as electric wires and hoses.

(Prior art) As shown in Fig. 1, it consists of a paper tube with a structure in which paper strips are pasted in multiple layers, a corrugated cardboard flange, and a short tube connector made of a metal plate with an outer flange for integrally connecting the two. It has a structure in which a push-in claw is pushed open and fixed integrally with the inner wall surface of the paper tube which is joined to the outside from the inner wall surface of the coupler into which the corrugated cardboard flange is fitted.

(Problems to be solved by the invention) In the above-mentioned conventional structure, the paper tube and short tube connector made of metal plate are more expensive than the collar body made of inexpensive material such as corrugated cardboard. There is a drawback that the cost is unavoidably high, and the collar pieces of the connector protrude from both sides of the collar body, making it unstable and bulky when a large number of connectors are stacked.

There was also a winding tool made only of inexpensive materials such as cardboard, but since it was made of paper, there was a problem in terms of strength, and depending on the material and weight of the linear object, the connection between the collar plate and the paper cylinder could be difficult. There were problems such as damage to the

(Means for Solving the Problems) In order to solve the above-mentioned drawbacks, the present invention aims to significantly reduce costs by using inexpensive and easily available paper materials such as corrugated cardboard for the entire material. It is designed so that the outer surface of the body is a uniform surface so that it can be assembled and stacked easily, and the inner wall surface of the collar body is curved at an obtuse angle with respect to the paper tube. is as follows.

(1) In the main body of the winding device, which consists of the left and right flanges 2, 2 and the paper cylinder 3 that can turn the paper strip, the outline and the small holes 10 at the peripheral end are placed in vertically symmetrical positions with the fold line M as the border. The inner and outer collar plates 4 and 5 integrally formed are folded in half to form the collar bodies 2 and 2, and the insertion protrusions 12 are formed by bending them into a circular shape with respect to the paper cylinder fitting hole 6 of the inner collar plate 4. The inverted trapezoidal glue allowance pieces 19 and groups of 19 formed at both ends of the paper tube body 3 formed by combining the and insertion slits 14 are expanded outward and fixed to the inner flange plate 4 with adhesive. , the reinforcing plate 7 whose outer dimensions are designed to fit into the inner cavity of the paper tube body 3 is pressed into contact with the outer flange plate 5 through an adhesive in an overlapping state, and the peripheral edge thereof is stapled (registered). trademark)
A paper winding device characterized in that it is configured by being joined and fixed by a fastening means such as the above.

(2) The paper tube fitting hole 6 of the inner flange plate 4 is formed in a dodecagonal shape, and the paper tube body 3 is formed in a dodecagonal shape and is fitted therein.Claim 1 of the utility model claim. Paper winder as described.

(Example) Reference numeral 1 denotes a winding tool body whose entire material is assembled and formed using paper materials such as corrugated cardboard, and includes left and right flanges 2,
2 and a paper tube body 3 on which a strip of paper can be bent as a substitute for a paper tube. First, it is assumed that the left and right flanges 2, 2 are the same, and only the left flanges 2, for example, will be explained.

In other words, the flange body 2 is
A two-piece assembly made by folding the inner and outer flange plates 4 and 5 in half, in which several small holes 9 for inserting fingers or stick-shaped objects are formed at vertically symmetrical positions on the outer line and the circumferential edge, respectively. A paper tube body 3 is placed in the center of the inner flange plate 4.
A paper cylinder fitting hole 6 is bored into which the paper cylinder fitting hole 6 is fitted. As will be described later, the paper tube body 3 is formed into a dodecagonal shape in this embodiment, and the fitting hole is formed into a dodecagonal shape in accordance with the shape. A shaft hole 8 is bored in the center of the central portion of the outer flange plate 5, and a rotation hole 9 is bored in the periphery of the shaft hole 8.

After the paper tube body 3 is fitted into the paper tube fitting hole 6, a reinforcing plate 7 whose outer dimensions are to be fitted into the inner cavity of the paper tube body 3 is adhered and fixed.

As shown in the unfolded state in FIG. 1, the paper cylinder 3 is formed by punching out a piece of vertically long paper material, and has a slight folding margin in the corresponding direction from the left and right ends 15 and 16. A large number of equally spaced transverse fold lines S are formed in the central paper portion 18 with a portion 17 remaining, so as to configure the paper cylinder 3 into a dodecagonal shape. Trapezoidal adhesive pieces 19, 19 are formed in a protruding manner.

An insertion protrusion 12 and an insertion slit 14 are integrally formed on the upper and lower ends 11 and 13.

This paper cylinder body 3 is formed by turning into a circular shape to connect the insertion protrusion 12 and the insertion slit 14, and the glue margin pieces 19, 19 groups formed at both ends of the paper cylinder body 3 are formed on the inner side. The glue allowance pieces 19 that have been inserted into the shaft holes 8 in the flange plate 4 and passed through are expanded outward and fixed to the inner flange plate 4 with adhesive, and then the outer side pieces 19 that are connected with each other with the fold line M as the boundary are expanded outward. The flange plate 5 is folded in half and pressed into contact with the inner flange plate 4 in an overlapping state via an adhesive,
The peripheral end portions are joined and fixed using a fastening means such as a stapler (registered trademark). Then, the reinforcing plate 7 attached to the outer flange plate 5 fits into the inner cavity of the paper cylinder 3 and functions as a reinforcing core. . Since the paper cylinder thus assembled has a prismatic shape, a cylindrical surface can be formed by further wrapping and fixing a piece of paper around this surface. 20 is provided in the center of the paper tube body 3 in which an escape hole 21 is bored to allow the core rod to be inserted through the shaft hole 8 and rotation hole 9 in the left and right flanges 2, 2. It is a central reinforcement.

(Effects) Since the present invention has the above-mentioned configuration, compared to the conventional winding device consisting of a paper tube, a corrugated cardboard flange, and a short cylindrical connector made of a metal plate with an outer flange for integrally connecting the two, In addition to realizing considerable cost and weight reductions, on the other hand, the structural weakness of the conventional paper-only structure has been solved by inserting protrusions 12 and inserts into both the upper and lower ends of the strip of paper that makes up the paper tube. By forming the slits 14 and connecting them, the strength against the weight of the linear object hanging in the direction of the central axis of the paper tube body is increased,
In addition, since the adhesive strips 19 and 19 groups at both the left and right ends of the paper tube are formed into an inverted trapezoid, the adhesive area can be increased, and these adhesive strips can be used on the inner flange plate. Since it is fitted into the paper tube fitting hole and adhered to the inner flange plate, its adhesion force can be greatly enhanced.

Moreover, since the outer flange plate and the inner flange plate folded back along the fold line M are polymerized and bonded with an inverted trapezoidal glue margin sandwiched therebetween, the bonding force between the paper tube body and the flange body is significantly increased.

Furthermore, the reinforcing plates 7 attached to the outer flange plate fit into both ends of the inner space of the paper tube, so that the paper tube can withstand the weight of the linear object hanging in the direction of the center axis of the paper tube. By reinforcing the winding tool, all of these structures work together to bring about an excellent effect that significantly improves the disadvantages of the winding tool being made of paper.
