Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of packing a laminated metal sheet and a package thereof, and more particularly to a method of packing a laminated metal sheet relating to a metal sheet of high quality and highly required to be rust-proof and moisture-proof and a package body thereof. .

[0002]

2. Description of the Related Art Normally, when packing metal sheets that are highly required to be rustproof and moistureproof, the metal sheets are stacked on a pedestal with a protective plate, and the side of the laminated metal sheet extending from the top end to the bottom surface of the pedestal is placed. Wrap the top and bottom of the waterproof packing paper in a waterproof packing paper, fold the upper margin of the waterproof packing paper on the upper surface of the laminated metal sheet, put the protective plate on it, and place the lower margin on the bottom surface of the pedestal. In order to protect the metal sheet from external shocks, the protective material on the upper surface and the side surface of the laminated metal sheet are covered with a metal or paper exterior material, and each edge of the rectangular parallelepiped exterior body thus formed. A single or double protective angle made of paper or metal is attached to the section (there are 12 locations), and band binding is performed to complete the package (for example, JP
5-278757).

The pedestal is usually made of wood, and wooden feet are attached to the lower surface of the pedestal. The pedestal and feet are integrally called a skid or a wooden skid.

[0004]

The outer surface of the packing paper is waterproof and does not cover the entire laminated metal sheet, but the end of the packing paper folded on the upper surface is a protective plate. It is pressed down with, and the exterior material is further covered on it, and the end of the packing paper folded into the lower surface of the pedestal is pressed down with a protective angle, so the intrusion of moisture from these ends Should be able to prevent it.

However, the rusting of the internal metal sheet has not yet been completely eliminated. There is a method to seal the edges of the packing paper with waterproof adhesive tape, etc.
Since the legs of the wooden skid are short and there is no space for people to enter under the pedestal, it is difficult to put tape around the underside of the pedestal, which impairs workability, and the tape cost and packaging cost increase. Economic efficiency is also impaired.

[0006] Therefore, an object of the present invention is to provide a method of packing a laminated metal sheet which can effectively prevent moisture from entering the inside without impairing workability and economy, and a packing body thereof.

[0007]

According to the present invention, a laminated metal sheet is formed directly on a pedestal with legs or through a protective plate, and the side surface extending from the lower surface of the pedestal to the top of the laminated metal sheet is left and right to be waterproof. In the method for packaging a laminated metal sheet, which includes the step of wrapping it in a flexible packaging paper, folding the lower margin into the lower surface of the pedestal, and pressing the ridges with a protective angle, the folding edge of the packaging paper on the lower surface is the bottom edge of the protective angle. It is a method of packing a laminated metal sheet, which is characterized in that it is protruded.

Further, according to the present invention, the pedestal with feet, the laminated metal sheet stacked directly on the pedestal or through the protective plate, and the side surface extending from the lower surface of the pedestal to the top end of the laminated metal sheet are covered with the upper and lower sides. In the package of the laminated metal sheet including the waterproof packaging paper having the lower margin folded on the lower surface of the pedestal and the protection angle in which the folded packaging paper is pressed by the ridges on the lower surface of the pedestal, It is a laminated metal sheet packaging body characterized in that the folding end of the packaging paper protrudes from the lower edge of the protective angle.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION The present inventors investigated the cause of rusting of a metal plate in a package, and as described below, found that there was a problem with the conventional packaging method, especially regarding the lower surface of the pedestal. It was FIG. 4 is a cross-sectional view of a main part of a package showing a problem of conventional packaging. As described above, the waterproof packing paper 9 is folded at the lower margin of the side surface into the lower surface of the pedestal 10A of the wooden skid. Conventionally, it is better to press the folding end 13 in a concealed state to prevent moisture. From the belief that entry can be prevented, this folding edge 13 is the side of the lower side of the protective angle (paper angle 7 and horizontal iron angle 5 in this example) (the side of the cross section of the protective angle that contacts the lower surface of the pedestal). The same shall apply hereinafter). FIG.
Reference numeral 11 denotes a protective plate at the bottom of the laminated metal sheet 12.

However, in fact, in the above conventional packing structure, the folding end 13 of the packing paper 9 has the protective angle (7,
5) Since it is located by retracting only the withdrawal allowance 15 shown by the dotted line from the lower end 14 of the lower side, the dew condensation water generated on the horizontal iron angle 5 and the rainwater that permeates the paper angle 7 are The fold end 13 wraps around the inner surface of the packing paper 9 that is not waterproofed, and easily enters the inside of the packing body. Thus, the invading water reaches the laminated metal sheet 12 inside and causes rust on the metal sheet. I knew that I would end up.

The present invention has been made on the basis of such a new finding. Contrary to the conventional technique, the lower surface folding end of the packing paper is made to protrude from the lower edge of the protective angle of the lower surface ridge. And FIG. 1 shows a cross-sectional view of a main part of a package showing the features of the present invention. In FIG. 1, 16 is a protrusion margin. The same members as those in FIG. 4 are designated by the same reference numerals and the description thereof will be omitted.

As shown in FIG. 1, in the present invention, since the folding end 13 of the packing paper 9 into the pedestal 10A protrudes from the lower end 14 of the protective angle (5, 7), the protrusion margin 16 is provided. , Condensation water or rainwater collected on the upper surface of the lower side of the protective angles (5, 7) should not be
Since it does not reach to, it does not go around to the inner surface of the packaging paper 9 from there. In addition, even if water is retained on the upper surface of the protruding portion 16, the bottom edge 14 of the protective angle (5, 7)
It does not go inside beyond the position where it was pressed.

As described above, according to the present invention, it is possible to effectively block the moisture invasion route from below into the inside of the package of the laminated metal sheet which is highly required to be rustproof and moistureproof. In addition, when implementing, whether the folding length of the packing paper to the lower surface is longer than the lower side length of the protective angle that presses this at the ridge,
Alternatively, it is only necessary to design so that the length of the lower side of the protective angle is shorter than the length of the bottom of the packing paper.
Since there is no need to change or add special packing procedures or add packing materials, workability and economic efficiency are hardly impaired.

A packing sheet of sex, 10 is a skid (wooden skid), 10A is a pedestal, 10B is a foot, 11 is a protective plate, and 12 is a laminated metal sheet. The vertical, horizontal, and vertical iron angles 4, 5, 6 and the paper angle 7 are collectively referred to as a protective angle.

The packing method of the packing body of the embodiment will be described below with reference to FIGS. 2 and 3. First, 1000 tinplate sheets having a plate thickness of 0.2 mm were stacked and placed on the pedestal 10A on which the protective plate 11 was laid. A foot 10B is attached to the lower surface of the pedestal 10A, the pedestal 10A and the foot 10B constitute a wooden skid 10, and the protective plate 11 is a 1.0 mm thick cardboard.

The side walls of the tin-plated metal sheet 12 thus stacked and placed together with the pedestal 10A and the upper and lower sides are left waterproof to provide waterproof packing paper 9 (external polyethylene coated kraft paper: coating thickness 20 μm, kraft paper 75 g / m ² ), the upper part of the packing paper 9 was folded on the upper surface of the laminated metal sheet 12, and the protective plate 11 was placed on it. Then, the lower surplus portion was folded into the lower surface of the pedestal 10A. In addition, when wrapping the side surface, this folding length is a standard size paper angle 7,
The length of the lower margin of the packaging paper 9 is adjusted so that it is longer than the lower sides of the vertical and horizontal iron angles 4 and 5.

Further, in order to protect the metal sheet from external impact, the top and side surfaces of the laminated metal sheet 12 are covered with a 1.0 mm-thick cardboard exterior material 8, and the top surface of the exterior body in the shape of a rectangular parallelepiped thus formed. To the ridge between the side and the side and the ridge between the sides,
The vertical and horizontal iron angles 4 and 5 and the hawk iron angle 6 were attached, and the paper angle 7 was placed inside and the vertical and horizontal iron angles 4 and 5 were placed on the ridges of the lower and side surfaces. At this time, the folding end 13 (see FIG. 1) of the packing paper 9 was protruded from the lower side of the paper angle 7 and the lower sides of the vertical and horizontal iron angles 4 and 5. In this example, the protrusion margin 16 (see FIG. 1) was about 5.0 mm.

Finally, 0.7 mm thick steel vertical, horizontal, and elastic bands 1, 2, and 3 were wound and bound with a tightening pressure of 7 kg / cm ² to complete a package. In the laminated metal sheet thus packed, no rust was generated due to water intrusion from the lower surface of the package. In this embodiment, the paper angle 7 and the vertical and horizontal iron angles 4 and 5 are used as the protection angle of the lower surface ridge, and the length of the lower surface of the packing paper 9 is the same as the standard size of the protection angle. However, the present invention is not limited to this, and the iron angle and the paper angle may be used independently, and the lower side of the protective angle is shorter than the folding length of the lower surface of the packing paper. May be designed to
