Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same or similar reference numerals are given to the same or similar parts. Also, when an element is referred to as " including " an element throughout the specification, it does not exclude other elements unless specifically stated to the contrary. It is to be understood that the present invention may be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. .

First, a metal roll packaging structure according to an embodiment of the present invention will be described in detail. FIG. 2 is a perspective view of a metal roll packaging structure (hereinafter abbreviated as "packaging structure") according to an embodiment of the present invention, and FIG. 3 is an exploded perspective view of the metal roll packaging structure. 4 is a cross-sectional view of a compressed paper pad according to an embodiment of the present invention.

2 and 3, the packaging structure includes a packaging material 200 for covering the exposed surface of the metal roll 20, and a fixing member 300 for fixing the packaging material 200. The metal roll 20 is generally cylindrical and has a hollow portion 22 therein. The diameter and the width of the entire metal roll 20 and the diameter of the hollow portion 22 are supposed to be standardized according to the product.

4, the packaging material 200 is made of a paper material so as to have a hygroscopic function, and is formed of a compressed paper pad having a predetermined thickness so as to have a predetermined thickness, Even if it is constituted by the compressed paper pad of the present invention. In this respect, it is preferable that the resultant thickness of the compressed paper pad is 10 to 15 mm, and the paper sheet may be manufactured by pressurizing the pulp with a high pressure in a laminated layer of thin paper sheets coated with an adhesive.

A waterproof coating layer 202 is provided on one surface of the compressed paper pad constituting the packaging material 200 to prevent moisture from penetrating from the outside. It is preferable that the waterproof coating layer 202 is partially infiltrated from one side of the compressed paper pad to a predetermined depth of the inside of the compressed paper pad 202. Accordingly, when the waterproof coating layer 202 is provided only on the surface, The moisture penetration prevention capability is completely eliminated, so that the compressed paper pad is deteriorated or the inner metal roll 20 is prevented from being corroded.

On the other hand, when the waterproof coating layer 202 is completely infiltrated in the thickness direction of the compressed paper pad, the function of the moisture absorption function of the compressed paper pad itself may be lost. Therefore, The penetration depth of the coating layer 202 is preferably 30 to 40% based on the thickness of the compressed paper pad.

Preferably, the waterproof coating layer 202 is formed of paraffin which is hydrophobic and has good adhesion and invasion to the compressed paper pad, as well as resistance and resistance to chemicals. The waterproof coating layer 202 may be formed by applying liquid paraffin uniformly to one side of a compressed paper pad through a process of pressing the compressed paper pad or separately after the production of the compressed paper pad, As shown in FIG.

As shown in FIG. 3, the wrapping material 200 includes a roll-type inner film 210 installed on a wall surface of the hollow portion 22 of the metal roll 20; A pair of donut-type cutouts 220 provided on the side of the metal roll 20; And a roll-type envelope 230 provided on the outer circumferential surface of the metal roll 20. This is because it is possible to improve the workability in the field by separately providing the packaging material 200 along each shape surface of the metal roll 20 and at the same time to ensure the covering of the entire exposed surface of the metal roll 20, (20), thereby making it possible to achieve durability and reliability of the packaging structure.

The inner surface 210 and the outer surface 230 of the wrapping material 200 have a width corresponding to the width of the metal roll 20 and are equal to the inner circumferential surface of the hollow portion 22 of the metal roll 20 and the outer circumferential surface length of the metal roll 20 And is rolled in the form of a roll in accordance with the inner peripheral surface of the hollow portion 22 of the metal roll 20 and the outer peripheral surface curved shape of the metal roll 20 when forming the package structure.

In this case, referring to FIG. 4, on the inner side of the roll-type inner skin 210 and the roll-type outer skin 230, that is, on the side contacting the surface of the metal roll 20 in the installed state, The curved surface 204 can be easily deformed. That is, when the curved surface is deformed by the corresponding bone, the compressive stress on the surface is relaxed, so that the curved surface modification of the inner surface 210 and the outer surface 230 is performed so as to completely conform to the curved surface profile of the metal roll 20, And the adhesion of the packaging material 200 to the hollow portion 22 and the circumferential surface of the metal roll 20 is improved. It is also advantageous to store the inner skin 210 or the outer skin 230 in roll form before and after packaging.

The processing of the troughs 204 with respect to the compressed paper pads may be performed in a pressing manner by using a pressurizing mechanism, and this pressing processing may be performed simultaneously with or separately from the compression manufacturing of the compressed paper pads. The surface on which the troughs 204 are formed may be a surface on which the waterproof coating layer 202 is formed as shown in Figure 4A in the case of the inner skin 210 and a surface on which the waterproof coating layer 202 is formed as shown in Figure 4 may be the opposite surface on which the waterproof coating layer 202 is formed as shown in FIG. Also, such a bone may be in the form of a continuous glue portion in the width direction as in the embodiment, but it may be intermittent.

On the other hand, in the case of the side cuts 220, since the side surface of the metal roll 20 is planar, it is not accompanied by a curved surface deformation when the package structure is formed, so that the corrugation on the endothelial sheet 210 or the sheath 230 as described above may be unnecessary have.

The fixing member 300 may include at least one member selected from corner castings 310 and 320, a waterproof tape 330 and band strips 340 and 350 as in the embodiment, All of which may be included.

The corner casting comprises a pair of inner ring-shaped corner castings (310) mounted on a boundary edge between the hollow portion (22) and the side surface of the metal roll (20) A pair of outer ring-shaped corner castings 320 mounted on the outer ring-shaped corner castings 320 may be selectively provided. The corner castings 310 and 320 are all ring shaped in the shape of a cross section and have a boundary edge between the side surface of the metal roll 20 and the inner side surface or the warp surface of the hollow portion 22, And protects the corresponding boundary edge of the metal roll 20 from the high tensile tension, particularly at the time of installation of the horizontal band strip 340 among the band strips.

The corner castings 310 and 320 are not particularly limited as long as they are made of a material having sufficient rigidity and corrosion resistance, and can be manufactured by casting a metal such as aluminum or molding a high rigidity resin. The dimensions of the corner castings 310 and 320 are determined according to the standard of the metal roll 20 and are recyclable for the metal roll 20 of the same standard after the packaging structure is disassembled.

Since the corner castings 310 and 320 are installed to cover a part of the packaging material 200, 210, 220 and 230, the corner castings 310 and 320 and the packaging materials 200 and 210 and 220 and 230 ) Can be selectively sealed by using an adhesive tape or silicone (not shown) or the like.

(Not shown) is coated on one surface of the waterproof tape 330. The exposed end of the rolled inner film 210 and the rolled outer film 230 is fixed as a flexible resin material, So that moisture is prevented from penetrating. It is preferable that the waterproof tape 330 is installed before the corner castings 310 and 320 when the package structure is formed.

The band strips 340 and 350 are made of a metal material such as aluminum and securely fix the corner portions 310 and 320 of the packaging material 200 and the corner castings 310 and 320 Thereby making the overall packaging structure complete.

In the embodiment, the band strips 340 and 350 are provided in two shapes, i.e., vertical and horizontal, and the vertical band strip 350 is formed in the shape of the metal roll 20 in the circumferential direction of the metal roll 20, As shown in FIG. The transverse band strips 340 are provided in a manner that passes through the hollow portion 22 of the metal roll 20 and surrounds the side and circumferential surfaces and is provided at regular intervals in the circumferential direction of the metal roll 20.

These band strips 340 and 350 can provide sufficient fastening force to the packaging material 200 (210; 220, 230) and the corner castings 310 and 320 by maintaining high tensile tension in the loaded state, 350 may be accomplished using welding, bolting, riveting, or a separate joining member (not shown).

Next, the inner film 210, the outer film 230 and the side film 220 are respectively attached to predetermined portions of the metal roll 20 as the packaging material 200 provided separately, and the waterproof tape 330 is attached to the inner film 210, And the end portion of the sheath 230 (see Fig. 5 (b)). In this case, when the inner film 210 is released from the inside of the hollow portion 22 by a roll having a radius smaller than the diameter of the hollow portion 22 of the metal roll 20, the diameter of the roll is expanded by the elastic restoring force of the compressed paper pad And is naturally brought into close contact with the inner surface of the hollow portion 22. The curved surface profile of the inner film 210 and the outer film 230 in the installed state by the troughs 204 formed on the inner surface of the inner film 210 and the outer film 230 is formed on the inner side surface of the hollow portion 22 of the metal roll 20, So that it is almost perfectly aligned with the curved surface profile of the main surface, so that reliable close contact is possible. Next, the inner and outer ring-shaped corner castings 310, 310 are formed on the side surface of the metal roll 20 by manual operation of the operator or by using a separate temporary member such as a tape (not shown) 320) (see Fig. 5 (c)). In this case, since the inner and outer diameters of the inner and outer ring-shaped corner castings 310 and 320 are manufactured in accordance with the standard of the metal roll 20, the installation state of the inner and outer ring-shaped corner castings 310 and 320 can be maintained without the band strips 340 and 350 being fastened have. In this state, the boundary gaps between the inner and outer ring-shaped corner castings 310 and 320 and the packaging material 200 (210, 220 and 230) can be selectively sealed using an adhesive tape or silicone (not shown) have. Next, the vertical and horizontal band strips 340 and 350 are successively joined together to complete the packaging process (see FIG. 5 (d)).
