[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and a package for packing a wire coil, and more particularly to a method for packing a wire coil.
The present invention relates to a method and a package for a rolled wire rod coil converged and bound by a binding band.

[0002]

2. Description of the Related Art Conventionally, many rolled wire rod coils wound and converged and bound in a coil form have been stored and transported as they are, but rusting that occurs during long-term storage and transport has occurred in products. Its value has been remarkably reduced, and the generation of rust has been regarded as a problem in recent years, particularly as products are upgraded. Therefore, in order to improve this, for example, using a rectangular packaging material that combines a synthetic resin film or cloth, or a packaging material that is formed by joining a sheet material that combines a synthetic resin film or cloth into a cylindrical shape, As shown in FIG. 4 and FIG.

FIG. 4 is an explanatory view of a packing method using a rectangular packing material. In this packing method, the converged and bound rolled wire coil C is lifted by inserting the hanging tool 21 into the inner peripheral surface C1, and in this state, a rectangular packaging material 22 is formed on the outer peripheral surface.
And the overlapping portion of the wound ends is stopped with an adhesive tape 23, and the packaging material 22 is formed into a cylindrical shape. Thereafter, it is placed on a packaging table (not shown) provided with a coil rolling prevention device, and with the hanging member 21 removed, both ends 24 and 25 of the cylindrical packaging material 22 are rolled into a rolled wire coil. The rolled wire coil C is packed by folding it back into the inner peripheral surface C <b> 1 of C and packing it into a shape along the outer shape of the rolled wire coil C. Then, if necessary, a packing tape (not shown) is wound around three to five places from the top of the packaging material 22 to the inner and outer peripheral surfaces C1, C2 and both end surfaces C3, C4 to pack the rolled wire coil C. You may be asked.

FIG. 5 is an explanatory view of a packing method using a cylindrical packing material. In this packing method, the converged and bound rolled wire coil C is placed on a packaging table (not shown) provided with coil rolling prevention, and in that state, wires 26 and 27 are provided at both ends to narrow the openings. Cylindrical packaging material 28
Is inserted into the inner peripheral surface C1 of the rolled wire coil C, and is opened in a cylindrical shape along the inner peripheral surface C1 of the rolled wire coil C, and a hanging tool (not shown) is inserted through the opening. lift. Thereafter, in a state of being lifted, one end 29 of both ends 29, 30 of the packaging material 28 is folded back to the outer peripheral surface C2 side of the rolled wire coil C, and the wire 26 is wound in the middle of the outer peripheral surface C2.
And the other end 30 is similarly folded back to the outer circumferential surface C2 side of the rolled wire coil C to form an outer circumferential surface C2.

[0005]

By the way, even if the above-mentioned packing is performed, rust may occur during long-term storage or transportation, and the product value may be significantly reduced. In the case of export products, there may be problems such as dew condensation in the packaging, and the problem of rusting still occurs, and improvement thereof is desired. Therefore, for example, attention has been paid to a method of vacuum-packing the entire product, which is performed with small-sized parts or simple-shaped parts, to prevent rust (see, for example, JP-A-5-178323). A packaging bag made of a composite material of the above was produced as a trial and packing was attempted.
Since it is a large cylindrical heavy object of 0 to 1300 mm, inner diameter of about 500 to 900 mm, and weight of 1 to 3 tons, it is necessary to use the hanging tool as described above. It is difficult to seal with no space inside, and there is a problem in workability and practicality.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and its object is to store the data in a warehouse or the like for a long period of time or to export to a region where the temperature is significantly different. It is an object of the present invention to provide a method and a package for packaging a wire coil that does not generate rust even during storage or transportation during a period and that can be relatively easily packed.

[0007]

In order to achieve the above object, a method of packing a wire coil according to the present invention (claim 1) is to provide a method of packing inner and outer peripheral surfaces of a wire coil formed into a cylindrical shape by binding. A method of packing a wire coil to be covered and packed by using a tubular packaging material, wherein one end of the packaging material is inserted into the inner peripheral surface of the wire coil, and the other end is folded back to form an outer peripheral surface. After covering the side, both ends of the packaging material are air-tightly joined, the air inside the packaging is sucked, and then the suction port is closed.

In the packing method according to the first aspect, the wire coil is housed between the inner and outer materials formed by folding back the cylindrical packaging material, so that the inner circumference of the wire coil is formed. The hanging part can be inserted through the surface part, and the handling of the coil can be made relatively easy. It can be airtightly bonded with a double-sided adhesive tape or an adhesive that has been applied. In addition, since the air inside the package is sucked after airtight bonding and the suction port is closed after that, the packing material can be packed in close contact with the inner and outer peripheral surfaces and both end surfaces of the wire coil, and the air inside the package is diluted. It is hard to cause dew condensation, and during long-term storage in a warehouse,
Alternatively, rusting can be prevented even during long-term storage or transportation during export to regions with greatly different temperatures.

In order to achieve the above object, a method of packing a wire coil according to the present invention (claim 2) is to form the inner and outer peripheral surfaces of the wire coil formed into a cylindrical shape by binding. A method of packing a wire coil to be covered and packed by using the wrapped material, wherein the wrapping material has a cylindrical shape formed so as to cover an outer peripheral surface of the wire coil, and an inner and outer circumference of the wire coil. With a length that can cover the surface and both end surfaces, it has a double-sided adhesive tape at one end of its outer peripheral surface,
One end of the wrapping material is inserted into the inner peripheral surface of the wire coil, and the other end is folded back to cover the outer peripheral surface. It sucks the air inside and then closes the suction port.

In the packing method according to the second aspect of the present invention, the wire coil is housed between the inner and outer materials formed by folding the cylindrical packing material, so that the inner circumference of the wire coil is formed. The hanging member can be inserted through the surface, the coil can be handled relatively easily, and the packaging material can cover the outer peripheral surface of the wire coil. The outer diameter of the wire coil can be easily packaged because the outer diameter of the wire coil is larger than the outer diameter of the wire coil. In addition, since a double-sided adhesive tape is provided at one end of the outer peripheral surface of the packaging material, the release liner is peeled off after the wire coil is housed between the inner and outer materials formed in a double form, so that the inner and outer materials formed in the double form are removed. The ends can be easily hermetically joined. In addition, since the air inside the package is sucked after airtight bonding and the suction port is closed after that, the packing material can be packed in close contact with the inner and outer peripheral surfaces and both end surfaces of the wire coil, and the air inside the package is diluted. And condensation hardly occurs,
Rust can be prevented during long-term storage in a warehouse or the like, or during long-term storage or transportation for export to an area having a significantly different temperature.

In the packing method according to the second aspect of the present invention, when the both ends of the packaging material are air-tightly bonded with a double-sided adhesive tape, the both sides are bonded while leaving a part of the release liner of the double-sided adhesive tape. After the air inside the package is suctioned from the part where the liner is partially left, the release liner can be removed and joined (claim 3). By sucking the air inside the package by such a method, there is no need to separately provide a suction hole, and the suction hole after suction can be easily sealed.

In order to achieve the above object, a package for a wire coil according to the present invention (claim 4) is provided such that the inner and outer peripheral surfaces and both end surfaces of a wire coil formed in a bundled and cylindrical shape are combined. It is covered with two cylindrical packaging materials, both ends of which are air-tightly joined, and the air inside the packaging is sucked.

In the above-described package, both ends of the packaging material are air-tightly joined, and since the air inside the package is thin, dew condensation hardly occurs. In addition, since it is airtightly packed, humid air and moisture can enter from outside even during long-term storage in a warehouse or during long-term storage or transportation such as export to a region with greatly different temperatures. Difficult, no rusting

In the wire coil packing method according to the first or second aspect, and further in the wire coil package according to the fourth aspect, the packaging material may be bound with a packing tape or the like. . By tying in this manner, the bulk of the packaging material can be prevented, and even if the airtightness of the packaging material is impaired during the handling of the wire coil after packing, the packing can be prevented from being out of shape. .
