2. Description of the Related Art Wiring for homes, buildings, factories, etc.
Although electric wires and VVF electric wires are used, these electric wires are generally used in the form of bundled electric wires wound in a ring shape and bundled for ease of storage, transportation and handling during use. I have. Most of the bundled electric wire wound in a ring shape is wrapped in order to protect the electric wire during storage and transport and to prevent collapse of the electric wire, and a donut-shaped electric wire bundle is used as the wrapping means. It is common that kraft paper is wrapped around and wound and packaged.

However, in the case of the above-mentioned wrapping by kraft paper, the amount used as a wrapping material increases, and it takes time to unwrap the kraft wrapping when using the electric cable. Because you ca n’t see
There is a problem (wrong product trouble) that wrong wires are delivered by mistake.

In recent years, as shown in FIGS. 4 and 5,
The wire bundle 6 wound in a ring shape is made of polyethylene terephthalate as a raw material, and a hole 8 of the wire bundle 6 is formed by a heat-shrinkable film 7 made of a uniaxially stretched heat-shrinkable plastic sheet that is thermally contracted only in the outer circumferential direction of the wire bundle. A heat-shrinkable film-wrapped bundle-wound electric wire 10 which has been covered and wrapped with an opening 9 communicating therewith has been proposed (JP-A-9-20237).
No. 2). The heat-shrinkable film-wrapped bundled electric wire 10 has a transparent film made of PET or the like used for packaging so that the inside of the package can be visually recognized in a packaged state. The wires can be pulled out.

[0005]

In such a heat-shrinkable film-wrapped wire bundle 10 as shown in FIGS. 4 and 5, a heat-shrinkable plastic material is used to heat-shrink a wire bundle 6 wound in a ring shape as shown in FIGS. A method is adopted in which the sheet 7 is used to cover and package an opening 9 communicating with the hole 8 of the wire bundle 6. The heat-shrinkable plastic sheet 7 is made of a transparent polymer resin such as PET, polyethylene (hereinafter, referred to as “PE”), and polypropylene (hereinafter, referred to as “PP”). The surface of the wire bundle 6 is applied to all surfaces of the outer periphery of the wire bundle 6 except for the inside of the opening 9 so that printing of the type and the name of the stored bundled wire can be seen from everywhere. . However, the packaged heat-shrinkable film-wrapped bundled wire is generally stored and transported by flat stacking. For this reason, the printing ink of the heat-shrinkable film as the packaging material is transferred to the bundled wire exposed on the inner peripheral end side where the overlapping surfaces are rubbed, or the color is transferred to the bundled wire, and the work is also performed. There is a problem such as soiling the hands and clothes of the elderly.

[0006] An object of the present invention is to prevent the exposed electric wire from being stained by the printing ink of the heat-shrinkable film as a wrapping material even when the packaged heat-shrinkable film-wrapped bundled wire is stored and transported in a flat state. Another object of the present invention is to make it difficult for workers' hands and clothes to be stained.

[0007]

In order to achieve the above object, a heat-shrinkable film-wrapped bundled wire according to claim 1 is provided.
In a heat-shrinkable film-wrapped bundled wire in which a wire bundle wound around a ring is covered and packaged with an opening communicating with the hole of the ring-type by a heat-shrinkable film, a band-shaped printing range is set on the heat-shrinkable film. The printing range is set to be equal to or less than the width of the outer periphery of the wire bundle. With this configuration, according to the first aspect of the invention, the heat-shrinkable film is a packaging material in which the exposed wire is a packaging material even when the packaged heat-shrinkable film-wrapped bundled wire is stacked and stored / transported. So that it will not be stained by the printing ink,
Further, it is possible to make the hands, clothes, and the like of the worker hard to be stained.

In order to achieve the above object, the heat-shrinkable film-wrapped bundled wire according to the present invention is characterized in that the print area of the heat-shrinkable film is subjected to a surface treatment for repelling the printing ink outside the set print area. It is composed. With this configuration, according to the second aspect of the present invention, since the printing is not performed with the printing ink except for the set print range, the packed heat-shrinkable film-wrapped bundled wire is stored and transported in a flat state. Even so, it is possible to prevent the exposed electric wires from being stained by the printing ink of the heat-shrinkable film as the packaging material, and it is possible to make the hands, clothes and the like of the worker hard to be stained.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the heat-shrinkable film-wrapped bundle-wound electric wire of the present invention will be described below. In FIG.
1 shows an entire heat-shrinkable film-wrapped bundled electric wire according to the present invention. In the figure, reference numeral 1 denotes an electric wire bundle obtained by winding and bundling an IV electric wire, a VVF electric wire, or the like in a ring shape, and 2 covers the entire outer peripheral surface 1A of the electric wire bundle 1 and the entire ring-side peripheral surface 1B on both sides. Shrink film (heat-shrink film) packaged with a heat-shrink film made of a transparent polymer resin such as PET, polyethylene (hereinafter, referred to as “PE”), or polypropylene (hereinafter, referred to as “PP”). . The electric wire bundle 1 wrapped in the above-mentioned ring shape is bundled with the shrink film 2 in which the electric wire bundle 1 is wrapped.
An opening 4 communicating with a hole 3 opening at the center of the hole is formed. Shrink film 2 which is a heat shrink film
In the above, the wire bundle 1 wound in a ring shape is covered and packaged by opening an opening 4 communicating with the hole 3 of the wire bundle 1. Reference numeral 5 denotes a binding band, which is used to press the wire bundle 1 so that it does not come loose when packing the wire bundle 1 wound in a ring shape.

The shrink film 2 is made of a heat shrink film, and the material of the shrink film 2 is PE.
A polymer resin such as T, PE or PP is used as a raw material. Generally, when a polymer film is stretched by uniaxial stretching or biaxial stretching, the molecules are oriented in the tensile direction (stretching direction). When the polymer film stretched in this way is heated, the stress due to the molecular orientation oriented by stretching is relaxed. Shrinks to return to the state of the polymer film before stretching. A shrink film for packaging electric wire bundles utilizes this property.
By stretching the thermoplastic film (polymer film) at an appropriate temperature and cooling in that state, the molecular chains are oriented in the stretching direction and the shape is fixed (the film in this state is a shrinkable film or stretched film). Film), then has the property of returning to its original dimensions when reheated,
Used for shrink wrap (shrink wrap).

The shrink film 2 made of the heat-shrinkable film in the present embodiment has, for example, an outer diameter of 360.
The wire bundle 1 wound in a ring shape having a diameter of 240 mm, an inner diameter of 240 mm, and a height of 120 mm is covered and packaged with an opening 4 communicating with the hole 3. This shrink film 2 is shown in FIG.
As shown in FIG. The roll of the shrink film 2 has, for example, a width of 220 mm and a length of 1200 mm, and has a thickness of 1 mm after stretching.
It is composed of a PET film stretched in the length direction to have a thickness of 00 μm. Specifically, this shrink film 2 is made of a polymer transparent resin such as PET, polyethylene (PE), or polypropylene (PP) as a material, and is produced as a raw material having a width of about 2 m at a manufacturing plant. The film is stretched uniaxially in the length direction, formed so that the thickness after stretching is usually 50 to 200 μm, and then cut again to a width of about 300 mm.

In the PET film of the shrink film 2, a printing range 2A is formed in an arbitrary width within a range of the width of the ring outer peripheral surface 1A of the electric wire bundle 1. The print area 2A of the PET film of the shrink film 2
Is, for example, a printing process of displaying the type and product name of a bundled electric wire to be stored later in a 120 mm portion of the ring outer peripheral surface 1A,
The printing is performed by a printer using a printing ink created by dispersing a pigment in a lacquer in which a rubber-based resin is dissolved in a solvent, and 50 mm portions on both sides of the ring-side peripheral surface 1B of the wire bundle 1 are used for printing. Blank part 2 not applied
B and 2C are formed. In this printing process, the roll width of the PET film of the shrink film 2 is set to 220 mm.
After that, it may be applied to one portion of this part, or a large number of printer heads arranged at every 220 mm in a state of a wide raw material may perform a large number of prints having a width of 120 mm or less at a time. Good.

The heat-shrinkable film-wrapped bundled electric wire 10 thus produced is stored in a horizontal position and stored and transported, and immediately before use, a binding band made of PP is cut to remove the necessary portion from the tire-shaped hollow portion. It is used while being pulled out and cut with a suitable length.
Are not printed on the ring-side peripheral surfaces 1B on both sides where they are in contact with each other, so that the electric wire is partially exposed and the ring-side peripheral surface of another packaged heat-shrinkable film-wrapped bundled wire 10 Even when the printing ink is in contact with the surface 1B, the printing ink printed on the heat-shrinkable film is not transferred to the exposed electric wire or is stained by color transfer.

FIG. 3 shows the entire heat-shrinkable film packaging material wound in a roll shape used in the heat-shrinkable film-wrapped bundled electric wire according to the present invention. In the figure, the heat-shrinkable film packaging material 11 wound into a roll used for the heat-shrinkable film packaging bundle wound wire has, for example, a width of 220.
mm, the length is 1200 m, and the thickness after stretching is 100
It is formed of a PET film stretched in the length direction to a thickness of μm. In the heat-shrinkable film packaging material 11, the printing range 11A is set in a band shape to an arbitrary width within the width of the ring outer peripheral surface 1A of the electric wire bundle 1. 1A width)
In addition to the above, a surface treatment is performed so that even if the printing ink is placed on the heat-shrinkable film packaging material 11, the heat-shrinkable film packaging material 11 is not repelled and printed.

That is, the heat-shrinkable film packaging material 11 has a packaging material end 11 corresponding to the ring-side peripheral surface 1B of FIG.
A 50 mm portion of each of B and 11C is subjected to a surface treatment for repelling a printing ink formed by thinly applying a lacquer obtained by dissolving a paraffin in a solvent, followed by drying. The ends 11B and 11C of the wrapping material are obtained by cutting the wide roll to a width of 220 mm and then performing the surface processing to repel the ink on both ends 50 mm after cutting the wide roll to a width of 220 mm. Is also good.

Therefore, according to the present embodiment, even if the printing is shifted during the printing process of the heat-shrinkable film and runs off to the surface-processed portions (packaging material ends 11B and 11C),
Since the thin paraffin surface treatment layer prevents fixing of the ink, it is not solidified on the heat-shrinkable film and can be easily wiped off.

The thus produced heat-shrinkable film-wrapped bundle wound wire is stored in a horizontal position and stored and transported.
Immediately before use, the PP binding band is cut and the required length is pulled out from the tire-shaped hollow portion and used while cutting, but the packed heat-shrinkable film-wrapped bundle wires are in contact with each other. Since the printing process is not performed on the ring side peripheral surfaces 1B on both sides, even if the electric wire is partially exposed and is in contact with the ring side peripheral surface 1B of the other packaged heat shrinkable film packaged and wound wire, the heat shrinkage is performed. The printing ink printed on the film is not transferred to the exposed electric wires or is stained by color transfer. In addition, the printing ink is less likely to be transferred to the hands or clothes of the worker or stained due to color transfer.

In this embodiment, PET is used as the packaging material of the bundled wire. However, any heat-shrinkable film that can contract and adhere to the stretched wire by heat may be used. Etc. can be used. Also,
In the present embodiment, the surface treatment for repelling the printing ink is performed by applying a thin layer of paraffin, but this is when the printing ink uses a rubber-based resin, and is combined with the resin used for the printing ink. Any resin that does not solidify the resin can be appropriately selected and used. Furthermore, in this embodiment, the bundled electric wire to be wrapped is constituted by an IV wire, but it is needless to say that the present invention can be applied to a VVF electric wire or the like, and the same effect can be obtained.

[0019]

The present invention is configured as described above, and has the following effects.

According to the heat-shrinkable film-wrapped bundled wire according to the first aspect, even when the packaged heat-shrinkable film-wrapped bundled wire is flatly stored and transported, the exposed wire is a packaging material. It is possible to prevent the printing ink of the shrink film from being stained and to make the hands, clothes and the like of the worker hard to be stained.

According to the heat-shrinkable film-wrapped bundled wire according to the second aspect, the printed heat-shrinkable film-wrapped bundled wire is stored in a flat pile because it is not printed with the printing ink outside the set print range. -It is possible to prevent the exposed electric wires from being stained by the printing ink of the heat-shrinkable film, which is a packaging material, even when conveyed.
