DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in more detail with reference to the drawings. FIG. 1 is an explanatory view of a packaging form of a hermetically-sealed package for a winding material according to the present invention. FIG. 1A is an explanatory diagram of the interior. FIG. 1B is a side view of the interior form. The take-up roll 1 is made by winding a metal single sheet or a metal sheet such as a laminate having a metal layer around the roll shaft 2, and is used by pulling out a required length from the take-up roll 1. To be done. In the present invention, in order to hermetically package such a roll material 1, as the interior material, as shown in FIG. 1 (a), a tubular body 3 made of a barrier film excellent in oxygen and water vapor barrier properties is used. A disc 4 having two central holes 5 is used. The tubular body can be formed by encapsulating a barrier film or pasting it with a palm, and has no cut-off portion and has a small use area, which is extremely economical.
The outer diameter of the disk 4 and the inner diameter of the center hole 5 are set to be larger than the outer diameter of the winding raw fabric 1 and the outer diameter of the raw fabric shaft 2 protruding from both ends, respectively. On the other hand, the diameter of the cylindrical body 3 made of the barrier film is set slightly larger than the outer diameter of the disc 4. Therefore, the tubular body 3 made of the barrier film can cover the winding material web together with the two disks 4 fitted from both ends of the material web shaft 2. In the hermetically-sealed package for roll-up roll according to the present invention, the tubular body 3 made of this barrier film is used.
And the space surrounded by the two discs 4 is shielded,
Form a closed system M.

Shielding means around the disk is performed as follows. As shown in FIG. 1A, two discs 4
A packing material 6 having a thickness of 1 to 3 mm is provided on the entire peripheral edge of the cylindrical body 3 with a barrier film, and the inner surface of the end of the cylindrical body 3 and the outer edge of the disk 4 are fastened together with the packing band 6. Is pressed in. On the other hand, the gap between the original shaft 2 and the central hole 5 of the disk 4 is also shielded by the method described later. Thus, a closed system M is formed as shown in FIG. 1 (b), and the winding web 1 is sealed therein.

FIG. 1C is a side view of the exterior form. FIG.
As shown in (b), the wound web roll 1 is further supported by both ends of the web shaft 2 exposed from the closed system M by supports 7 made of wood or the like, and in that state, a wooden frame or a reinforced cardboard box. The outer packaging material 8 is used to form the wound original fabric hermetically sealed package 10. As is clear from the above, the wound original fabric hermetically sealed package 10 according to the present invention is doubly packaged with the interior material and the exterior material, and the hermetically sealed system M is formed therein.

FIG. 2 is an explanatory view of an example of the tightening band 7. The tightening band is formed by connecting at least three arcs that divide the circumference into three parts so that the inner diameter can be adjusted according to the outer diameter of the disc 4, and the adjust fastener 12 is provided at that one position. The outer edge of the disk 4 can be tightened with an arbitrary tightening force. As shown in FIG. 1 (b), both ends of the cylindrical body are shielded by covering the outer edge of the disk 4 with the cylindrical body 3 made of a barrier film and tightening the tightening band 7.

FIG. 3 is an explanatory view of the shield means around the original shaft. FIG. 3A is a side view of the shield portion of the original shaft, and FIG. 3B is an enlarged sectional view thereof. FIG. 3 (a),
As shown in (b), the shield member of the original shaft 2 is a disc 4
The inner and outer flanges 11 and 12, which can be fitted in the center hole 5 of the inner and outer sides of the disk 4 by the tightening screws 13 provided with caulking material, the disk 4 and the inner and outer flanges 1
Tightening screw 1 that penetrates 1 and 12 and fixes these three
3, a spacer 14 and an inner nut 15 that are provided between the outer flange 12 and the original shaft 2 and slide on the original shaft 2.
Consists of inner flange 11 and spacer 14
Three O-rings are provided between the inner flange 11 and the outer flange 12, and between the inner flange 11 and the inner surface of the disc 4. As shown in FIG. 3 (b), when the inner nut 15 is turned and the spacer 14 is pushed in, the O-ring provided between the inner flange 12 and the spacer 14 is deformed and the space between the inner flange 11 and the original shaft 2 is changed. Shield. On the other hand, the space between the inner flange 11 and the outer flange, and the space between the inner flange 11 and the inner surface of the disk 4 are already shielded by the O-rings previously inserted between them when tightening with the tightening screw 13. As described above, by using three O-rings on one side of the original fabric shaft 2 to shield the three places, the circumference of the original fabric shaft 2 is completely shielded, and Together with the shield, a closed system is completed. The above shield member and disk 4
Can be repeatedly used, and the barrier film 3 can be repeatedly used in some cases. Moreover, since there is no so-called wrapping operation that is seen in general packaging, the barrier film is less likely to wrinkle, and aluminum foil can be used as a barrier material. Further, the amount of the barrier film used can be small because the use form is a tubular body. Therefore, initial investment of the shield member etc. is required, but in the long term, it is more economical than the conventional method of disposing of the moisture-proof or rust-proof packaging material once each time. It is possible to increase reliability.

The barrier film is required to have excellent oxygen and water vapor barrier properties, and in order to impart this barrier property, it is desirable to use an aluminum foil having a thickness of 9 μm or more. However, depending on the type of target metal, transportation and storage conditions, an aluminum vapor-deposited or silica vapor-deposited film, an ethylene-vinyl alcohol copolymer exhibiting excellent oxygen barrier properties at a humidity of 70% RH or less
It is possible to appropriately select and use a film such as a cyclic polyolefin resin having excellent moisture resistance. Furthermore, if a rust preventive agent or a desiccant is used alone or in combination in the closed system obtained by each interior material and the shield member, a further excellent antioxidation effect is exerted on the metallic material roll 1. be able to. The rust preventive used here is a corrosion inhibitor that turns into a gas at room temperature and suppresses the electrochemical reaction of rust generation by sublimated gas, and iron, aluminum, tin, zinc, copper, brass, etc. Since there are some non-ferrous metals that are suitable for each, they may be appropriately selected and used according to the metallic raw material 1 to be targeted. Further, a desiccant such as silica gel may be used together to maintain low humidity. The disk 4 may be made of metal or plastic as long as it is a material capable of producing the dimensional accuracy, and it is desirable that the disk 4 does not cause a deviation in the dimensional accuracy with repeated use.
The tightening band 7 is not limited to the one described above, and any band may be used as long as it has an appropriate tightening force.
Regardless of whether the material is metal or plastic, the tightening mechanism and molding method are free. However, it is desirable that it is lightweight, compact, and stable.

EFFECTS OF THE INVENTION A hermetically sealed package 10 for a roll of roll according to the invention
According to this, it is possible to switch the conventional physical distribution of the metal winding material in the low temperature and low humidity atmosphere to the normal room temperature distribution without any temperature and humidity control, and to prevent the entire winding operation. Instead of rust wrapping, only the barrier film formed into a tubular shape is required, and since the tubular shape is retained until the end, wrinkles are less likely to occur, and it is possible to use aluminum foil effectively. Not only the barrier film but also the barrier film can be repeatedly used in some cases, so that the total cost of logistics can be significantly reduced in the long term, and the shielding means according to the present invention can provide a reliable, high-quality metallic raw material. Anti-supply is possible.
