Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a binding band for winding and binding several bundled wires.

[0002]

2. Description of the Related Art In general, electric wires (wires) used for wiring in houses, buildings, factories, etc. are bundled in a ring shape for ease of storage, transportation and handling during use. Many usage forms have been adopted. As shown in FIG. 5, the bundled electric wire 3 is usually wound around the electric wire 2 in a fixed length in a ring shape and bound, and is bound by winding a binding band at appropriate places (usually two to four places).
This binding band is generally a band-shaped band as shown by reference numeral 51 in FIGS. 5 and 6, and polypropylene is used for its material. That is, the polypropylene band 51 is formed by winding the electric wire 2 in a ring shape to form the bundled electric wire 3, then winding the electric wire 2 around a plurality of places (two places in FIG. 5), overlapping both ends, and setting this overlapped place. It is fixed by heat fusion or by fixing the overlapped portion with a seal fitting or the like. When the electric wire 2 is taken out from the bundled electric wire 3 at the time of actual work, the polypropylene band 51 is cut to release the binding, and the electric wire 2 is taken out.

[0003]

However, since it is rare to use up all the electric wires 2 in one operation, it is necessary to bundle the remaining electric wires 2 in a ring shape again and store them in order to store them. However, when re-binding the bundled electric wire 3 after use, the polypropylene band 5 cut once is used.
When using No. 1, it is necessary to overlap the cut portions again and heat-bond them again, or fix them with a seal fitting and re-bind them, which is troublesome. In order to re-bind with heat fusion or a seal fitting, it is necessary to overlap the parts to be bound, especially when re-binding after removing a small amount of the electric wire 2 from the bundled electric wire 3. In addition, there is a problem that the shape of the bundled electric wire 3 is distorted, the bundle becomes thick, and the length of the polypropylene band 51 necessary for rebinding is insufficient.

[0004] Further, the material of the polypropylene band 51 is hard, and if the band is tightly bound, the electric wire 2 will be damaged, and when the operation of cutting the polypropylene band 51 is performed, the worker cuts his hand due to the hardness of the material. In some cases, such problems as inconveniences were caused.

[0005] It is an object of the present invention to improve a binding band and improve handling and safety during work.

[0006]

In order to achieve the above object, a binding band according to claim 1 binds a plurality of bundled wire rods, and comprises a stretch film or a stretch film extending beyond its original length. It is characterized by being made of wrap film. According to the first aspect of the invention, when the binding wire is wound around an arbitrary portion of the bundled electric wire while being pulled, the bundled electric wire is bound. When reuniting,
Rebinding is performed by winding the bundled wire around the bundled wire while pulling the binding band. In order to achieve the above object, the binding band according to claim 2 is characterized in that the binding band according to claim 1 has mutual adhesion. According to the second aspect of the present invention, the binding band is wound around the bundled electric wire, and the binding bands are simply overlapped with each other.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a binding band according to the present invention will be described below with reference to the drawings. In this embodiment, a case where an electric wire is used as a wire will be described as an example. FIG. 1 shows an embodiment of a binding band according to the present invention. In FIG. 1, reference numeral 1 denotes a binding band wound around a bundle of electric wires wound in a ring shape and is formed of a stretch film. Also, reference numeral 2
Denotes an electric wire, and reference numeral 3 denotes a bundled electric wire obtained by bundling and winding the electric wire 2 in a ring shape. The binding band 1 is formed in a band shape, and can be wound around an arbitrary position of the bundled electric wire 3. Therefore, the bundled electric wire 3 is connected to the binding band 1
Will be united.

In the present embodiment, the binding band 1 formed in a belt shape may have another shape. Although the bundled electric wire 3 is bound at two places, the number of the bundled places can be increased or decreased in consideration of the size of the bundle and the stability at the time of bundling. Also, the position where the bundled electric wire 3 is bound by the binding band 1 can be freely determined. Further, the number of times the binding band 1 is wound around the electric wire 2 is one winding. However, depending on the thickness and stability of the bundled electric wire 3, the number of times the binding band 1 is wound twice or three times according to the situation. It can be changed.
Examples of a material serving as a base material of the binding band 1 include polyethylene, polypropylene, poly-4-methylpentene-1, ethylene acetate acrylate, and olefin-based materials (EVA, LL).
DPE). Further, the binding band 1 may be a multilayer film formed by freely combining the above materials. FIG. 2 shows an example of the multilayer film. In FIG. 2, reference numeral 4 denotes a binding band made of a stretch film composed of three materials, reference numeral 5 denotes, for example, a layer of polyethylene, reference numeral 6 denotes, for example, a layer of ethylene acetate acrylate, and reference numeral 7 denotes a layer of, for example, polypropylene. I have.

The binding band 1 has mutual adhesion and can be easily brought into close contact with or separated from each other without damaging the films. In order to produce tackiness, a tacky material such as polybutene or polyisobutylene may be kneaded into the above resin or coated on the surface. Thereby, after the electric wire 2 is taken out from the bundled electric wire 3 and used, when the binding band 1 is bound again, the binding bands are simply overlapped with each other without using a heat seal or a seal fitting as in the related art. Thus, rebinding can be easily performed. Further, the adhesiveness of the stretch film is such that the films adhere to each other, but hardly adhere to other films, so that the surface of the electric wire 2 is not broken.

FIGS. 3 and 4 show drawings relating to the stretchability (elongation) of the stretch film. FIG.
In the above, “+ α” indicates the stretchability of the binding band 1. Reference numeral 51 in FIG. 4 indicates a conventional polypropylene band. The binding band 1 in FIG. 3 and the polypropylene band 51 in FIG.
Have the same length for comparison. The polypropylene band 51 has no stretch property. On the other hand, the binding band 1 is extended by the amount indicated by “+ α” by being pulled. When the binding band 1 is extended by “+ α”, a small amount of the electric wire 2 is pulled out from the bundled electric wire 3, and even if the shape of the bundled electric wire 3 is lost and it becomes difficult to re-bind the electric wire 2, the bundled electric wire 3 is removed.
Can be easily re-bound.

Incidentally, the stretch property indicated by the above-mentioned "+ α" will be additionally explained. The degree of stretchability of the binding band 1 suitable for binding the bundled electric wire 3 in the present invention is Ts: about 10 to 20 MPa, and elongation (E) is preferably about 300 to 800. Higher values of Ts / E also allow more binding. The stretchability of “+ α” changes depending on the strength of the pulling force on the binding band 1.

Although the binding band 1 of the present invention has been described as being made of a stretch film, the same effect can be obtained by using a wrap film (not shown) instead of the stretch film. That is, the wrap film has a stretch property extending beyond the original length, and like the stretch film, the wrap film also has mutual adhesion. The method for generating the tackiness is the same as the above-described method for the stretch film. Wrap film is the material
Polyvinylidene chloride, polyethylene, polypropylene,
Resins based on poly-4-methylpentene and the like can be mentioned. The wrap film may also be a multilayer film formed by freely combining the above-mentioned base material, like the above-mentioned stretch film. The wrap film and the stretch film have some differences in strength and stretchability, and can be selected by an operator according to the use such as the thickness and amount of the bundled electric wires.

[0013]

Since the present invention is configured as described above, it has the following effects.

According to the first aspect of the present invention, the binding band binds a plurality of bundled wires, and is made of a stretch film or a wrap film extending to an original length or more, so that the bundled wires are easily bound. , Can be reunited. In addition, since stretch films and wrap films are highly flexible, they do not hurt the wire rod even if the binding band is tightly tied, and prevent problems such as workers cutting their hands when cutting. Can be.

According to the second aspect of the present invention, since the stretch film and the wrap film have mutual adhesiveness, even when the band is cut once and then re-banded, the band is thermally fused, It can be easily re-bound without being fixed with a seal fitting.
