The present invention relates to a bobbin for storing cables and rope-type products in a round shape. After the use and storage of cables and other rope-type products, the bobbin is generally collected and discarded without reuse. Therefore, there is environmental pollution and unnecessary waste of resources, and this is to be improved. In particular, in recent years, with the spread of 3D printers, the use of filaments used for 3D printing is rapidly increasing. It is considered to protect the environment as it is a biodegradable material using an eco-friendly plastic made from corn starch called PLA. However, since PLA is sold almost entirely on bobbins formed of plastic injection molding, 3D printing technology may be environmentally friendly, but the surrounding technology still uses technology that pollutes the environment, which is a problem.

The present invention intends to use the following problem solving means in order to solve the above problems.

In the environmentally friendly biodegradable prefabricated integrated paper bobbin,

The development of the prefabricated integrated paper bobbin is

Six vertically long rectangles forming the paper tube of the prefabricated integrated paper bobbin are provided adjacent to each other in the center, and the vertical length of the rectangle is formed by the width of the paper bobbin cable and other rope-type products.

The present invention provides a bobbin by folding paper, and is intended to replace most of the existing bobbins made of plastic injection molding, and some made of paper materials are also made of paper tubes and pads, respectively, and assembled, all of which are made of paper. There has been a problem with not being configured.

The invention of the present application was invented to solve the above problems, and the effects of the invention of the present application will be described using the drawings as follows.

1 is a perspective view of a paper bobbin of the present invention. The pad is provided vertically, and a branch pipe is connected to the pad at the center. A cable hook groove is provided on one side of the branch pipe to secure the cable to be wound by knotting and inserting the end of the cable, for example, when winding the cable.

2 is an exploded view of the paper bobbin of the present invention. If six rectangles of the same size are provided in the middle to provide the branch tube in a hexagonal shape, the width of the six rectangles is wider than the six rectangles having the width of the circumscribed circle of the regular hexagonal cross section made by assembling the six rectangles at both ends. These are provided at the left and right ends of the six rectangles, respectively. The wide rectangle functions as a paper tube center reinforcing plate for reinforcing the strength of the paper tube by combining with each other inside the six rectangles constituting the paper tube. The upper and lower ends of each of the paper tube center reinforcing plates provided at the left and right ends are provided with bobbin pads, respectively. The shape of the pad may have a semi-circular, semi-elliptical or polygonal shape depending on the use, but in the present application, as shown in FIG. 2, a wide 'V' shape is the same.

Figure 3 is a view showing the joint in the developed view for assembling the paper bobbin of the present invention, Figure 4 is a view showing the position for bonding the pad of the paper bobbin of the present invention. It has been exemplified to use double-sided tape to promote the convenience of assembly, but it is more preferable to use starch paste in terms of considering the environment.

As shown in Fig. 3, the upper point A' and the point A'' are positioned at the point A, and the lower point B' and the point B'' are aligned with the point B, and the branch center provided at the left and right ends of the development view Attach the reinforcing plate. When adhered in this way, a hexagonal paper tube is formed, and two pads are rotatably attached to the top and bottom respectively. The pad branch tube coupling portion provided at the center of the four pads has three sides cut, and one side is coupled to the pad. The pad paper tube coupling portion is folded and coupled to the inside of the paper tube so that the pad does not move and is bonded and fixed to the paper tube. It is also attached with double-sided tape or starch paste. When the four pads are adhered to the inside of the paper tube in this way, the paper bobbin of the present application is made as shown in FIG. 1 .

5 shows the increase in strength by the paper tube center reinforcing plate provided inside the paper bobbin of the present invention. Of course, the durability of the paper jobbin of the present invention can be increased by adjusting the thickness of the paper used. However, the feature of the present application is that the paper tube center reinforcing plate is provided to reinforce the inner center of the paper tube by assembling, so that it can be supported even when the cable and rope type products are wound on the paper bobbin of the present application and stacked on the side. provides strength.

6 is a diagram showing that one side of the pad paper tube coupling part provided in the pad of the paper bobbin of the present invention is folded to increase the mechanical strength. The C line with the pad folded and the D line, which is the pad paper tube coupling part combined with the paper tube in a folded state, increased compression and elongation strength in the folded direction by folding. It can be seen that the strength is also increased in the direction.

That is, in the present invention, while making a bobbin by folding eco-friendly paper, the pad is mechanically reinforced by providing the configuration of the paper tube center reinforcing plate and the pad paper tube coupling portion, which is the pad coupling portion, in order to solve the lack of strength of the paper. In addition, 5 adhesive parts are provided for easy assembly.

7 is a diagram further comprising an RFID tag that stores information such as the type, length and type of the cable on one or both sides of the environmentally friendly biodegradable prefabricated cable bobbin and reads it with a contactless reader in order to use the present invention more productively; to be. The RFID tag may be made of thin paper and may be adhered, but may be thick in order to increase the strength of the pad of the present invention, and may be made larger in size than that of the pad.

8 is a pad reinforcing plate for reinforcing the pad of the environmentally friendly biodegradable prefabricated cable bobbin of the present invention, and may be in the form of a rhombus and a chamfered edge of the rhombus. An RFID tag may be further provided on the front or rear surface of the pad reinforcement plate.

9 is a view of folding and assembling a coupling part for coupling the pad reinforcing plate to the pad.

Fold the inner line of the rhombus-shaped double line inward, and fold the outer line outward. When assembled in this way, a rhombus-shaped space is formed as shown on the right side of FIG. 9 .

10 is a view showing the combination of the pad reinforcement plate and the pad forming the rhombus-shaped space. In order to maintain the rhombus-shaped space provided in the pad, the point where the two pieces of the pad meet may be bonded or not.

By further providing a pad reinforcing plate in the rhombus-shaped space provided in the pad, the eco-friendly biodegradable prefabricated cable bobbin of the present invention is strong and can be used for a long time because the pad strength is reinforced. The pad reinforcing plate can be adhered to further increase the pad strength, but for more eco-friendly use, the pad reinforcing plate with RFID is wound around an environmentally friendly biodegradable prefabricated cable bobbin and can be recovered and reused at the time of shipment.

The configuration of the invention showing the above-described effects of the present application is as follows.
