DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for packing a metal sheet coil, and more particularly to a method for efficiently and safely packing a metal sheet coil which is required to have high quality and high rust and moisture resistance.

[0002]

2. Description of the Related Art In general, a metal plate such as a steel plate (hereinafter, described as a steel plate) is wound in a coil shape and transported or stored in a packed state. When packaging steel sheet coils, it is required that both ends of the coil be well-shaped in addition to the outer circumference and the inner circumference of the hollow part. Particularly, how to treat the vicinity of the boundary between the inner circumference and the end face is required. Is one of the packing points.

FIG. 7 shows an example of a packing structure of a normal steel coil.
This will be described with reference to FIG. FIG. 7 is an external perspective view of a package in which a steel plate as a content is covered with an exterior material, and FIG. 8 is a cross-sectional view showing the structure of the package shown in FIG. This packing structure is, as shown in FIG. 8, composed of an inner peripheral plate 2 in which the inner periphery of a steel plate 1 wound on a coil serving as a content is formed into a cylindrical shape, and a disk-shaped side plate 3 having a central hole on the side surface. The outer peripheral surface is covered
Covered with.

Further, in order to prevent damage when the inner diameter hole is lifted by a crane or a forklift, the reinforcing cap 5 is attached and then tightened by a steel plate belt 6. For coils that are susceptible to damage, such as coils for export, steel outer materials may be attached to the inner periphery, outer periphery, and side surfaces before the reinforcing cap is attached, but the inner peripheral plate 2,
The structure covered by the side plate 3 and the outer peripheral plate 4 is basically the same.

[0005] One of the problems in this packing structure is a waterproof treatment of a connection portion between the inner peripheral plate 2 and the side plate 3. The package may be left outdoors or exposed to a natural environment such as rain or snow during transportation, or may be transported by truck, ship, or the like. In such a case, there is a problem that rainwater or the like intrudes from a gap between the inner peripheral plate 2 and the side plate 3 to cause rust or the like.

Therefore, the inner cylinder of the inner peripheral plate 2 is made longer than the coil width to protrude from the side surface of the coil, and a rectangular cut is made in this portion, and the cut is opened outward by folding the cut outward. Adhesion between the notch and the side plate 3 is often employed, but it has not been possible to completely prevent rainwater from entering through the gap between the notch. Conversely, inner peripheral plate 2
May be formed in a cylindrical shape corresponding to the coil width, a slit may be cut in the center hole of the side plate 3, and the surface may be folded back on the surface of the inner peripheral plate 2. However, the situation is the same. If these cuts are reduced to the required minimum, the gap between the cuts will be reduced, but it will not be possible to eliminate them, and it will take a great deal of labor and time to cut the strip into the required minimum. Has occurred. Further, when an adhesive is used for bonding, moisture and harmful gas are generated, which may cause rust on the steel sheet, which is not preferable in quality.

[0007]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and to provide a method for packing a steel sheet coil which can ensure the waterproofness with a simple operation.

[0008]

According to a first packing method of the present invention, a metal plate coil, a perforated disk-shaped side plate abutting on both side surfaces of the metal plate coil, and a center portion of the side plate are provided. In a metal plate coil package comprising a cylindrical inner peripheral plate inserted into a hole, a waterproof adhesive in which a connecting portion between the side plate and the inner peripheral plate is stuck over the side plate and the inner peripheral plate. Characterized by being covered with an elastic elastic body.

In a second packing method according to the present invention, a metal plate coil, a perforated disk-shaped side plate abutting on both side surfaces of the metal plate coil, and a hole inserted in the center of the side plate. The inner peripheral plate is formed longer than the metal plate coil width, at least one end is cut into a strip shape, and a portion of the inner peripheral plate longer than the metal plate coil width is folded back. In the metal plate coil package closely adhered to the side plate, the connection portion between the side plate and the inner peripheral plate, the side plate,
It is characterized by being covered with a waterproof adhesive elastic body stuck over the side plate and the folded portion of the inner peripheral plate which is in close contact.

[0010]

According to the present invention, a waterproof adhesive elastic body which is attached over the inner peripheral plate 2 and the side plate 3 is attached to the connecting portion between the inner peripheral plate 2 and the side plate 3. The gap between the parts was completely sealed. Although various forms and materials can be considered as the waterproof adhesive elastic body,
For example, a commercially available sponge tape (a sponge-like resin having an appropriate thickness formed in a tape shape and a non-drying adhesive applied to the front surface or the back surface) is preferable.

According to the first aspect of the present invention, the inner peripheral plate,
After attaching the side plate to a predetermined position, the inner peripheral plate and the side plate are bonded with a waterproof adhesive elastic body, so that the gap between the inner peripheral plate and the side plate can be sealed, and the waterproof property can be improved. . Further, since the adhesive elastic body is used, it can be completely stuck over the entire circumference of the circular hole, and no wrinkles or tears occur on the inner peripheral plate or the side plate.

According to the second aspect of the present invention, after the inner peripheral plate edge is cut into a strip shape, a waterproof adhesive elastic body is attached to the strip-shaped cut portion. Then, when the cut portion is folded in one direction and is brought into close contact with the side plate, a gap between the cut portions generated when the cut portion is folded is sealed, so that water can be prevented from entering through the gap. Further, since the adhesive elastic body is used, it can be easily folded at the time of folding, and can be sealed over the entire circumference.
