Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire element of a brush for scraping off a label attached to a container, a product or the like, and a soft wire material which can be used for a rope for packing, climbing or the like.

[0002]

2. Description of the Related Art In order to recycle and reuse beer bottles, it is necessary to once remove the label attached at the time of collection. The label is usually attached to the bottle with a strong adhesive so that it does not peel off easily during distribution, so conventionally, a rotating brush was pressed against the bottle.
It was designed to be scraped off by rubbing the tip or side of the brush wire.

If the strands of this brush are too soft, the labels and adhesives will not be sufficiently scraped off, and if too hard, the surface of the container such as a bottle will be scratched, reducing the commercial value and reducing the strength of the container. Let Therefore, conventionally, a material such as plastic or rubber has been used as the brush wire.

However, with a brush element wire made only of plastic or rubber, when the brush is continuously rotated for a long time, cracks are gradually generated and grow due to repeated bending, and finally it breaks and falls off. After many brush strands have fallen off like this, the brush loses the ability to scrape off the label and its adhesive, but with conventional brushes it takes a relatively short time to do so. , There was a problem that I had to immediately replace it with a new brush.

In order to solve such a problem, the present applicant has already devised a brush element wire in which a twisted yarn is arranged at the center and a soft elastic material containing fine particles of an abrasive is arranged around it. Japanese Patent Application No. 1-46566).

[0006] Conventionally, as the rope material, in addition to those obtained by twisting only fibrous materials such as natural fibers and synthetic fibers, rubber strands such as ropes for fixing luggage on a luggage carrier of a bicycle are used. There are things that can be stretched by twisting.

[0007] The packing rope containing the rubber strands has the effect of strongly fixing the load due to its own expansion and contraction force, but the rope must first be loaded at a position where the rope becomes the shortest. Due to vibration during transportation, the position of the rope gradually shifts toward the shorter route and the rope shrinks. In this case, the force for fixing the load may be weakened, or the effect of fixing the load may be lost altogether, and the rope may be unwound from the load naturally.

If the load is a hard object having a sharp corner, the rope may be worn out at this corner due to vibration during transportation. This was inevitable even with a retractable rope.

As for the problem with such a rope, the twisted yarn is arranged in the center and a soft elastic material such as rubber is arranged around it as described above (abrasive may be mixed with the soft elastic material). The use of soft wire solves to some extent. That is, since the periphery is made of a soft elastic material such as rubber, friction with the luggage is increased, and the displacement of the rope is unlikely to occur. In addition, the soft elastic material on the surface of the rope softly covers the sharp corners of hard objects,
The chance of rope breaks is reduced.

[0010]

In any case of the above-mentioned brush wire and rope material, the above-mentioned problems are solved by making the cross-sectional shape of the soft wire material different, for example, square, rectangular or star-shaped. be able to. That is,
By rubbing the label or the adhesive at the corners of these deformed soft wires, the force for scraping them off is further increased.
Further, when used as a rope, the frictional force with the luggage is further increased.

However, as a conventional method for manufacturing the above-mentioned soft wire, the above-mentioned application describes a method of impregnating the rubber by passing the twisted yarn through a rubber solution. Can only be manufactured. The present invention provides a method for manufacturing a soft wire material which can have a different cross-sectional shape.

[0012]

Means and Actions for Solving the Problems The first method for manufacturing a soft wire according to the present invention, which has been made to solve the above problems, comprises:
It is characterized by including the following steps. i) A fluidized soft elastic material is arranged around the fibrous wire, and simultaneous extrusion is performed from a nozzle having a predetermined shape. ii) By solidifying the soft elastic material, a soft wire in which rubber is arranged around the fibrous wire is obtained.

The shape of the nozzle used in step i) can be a circular shape, a rectangular shape, or a star shape.

A second manufacturing method of the present invention is characterized by including the following steps. i) The fluidized soft elastic material is coated on both sides of the sheet-shaped fibrous body. ii) A soft elastic material is solidified to form a sheet-shaped composite. iii) A soft wire is obtained by cutting the composite into elongated pieces.

A third manufacturing method of the present invention is characterized by including the following steps. i) Fluidized soft elastic materials are arranged on both sides of the sheet-like fibrous body, and coextrusion is performed from a slit having a predetermined shape. ii) A sheet-shaped composite body is obtained by solidifying the soft elastic material. iii) A soft wire is obtained by cutting the composite into elongated pieces.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the first method of the present invention will be described with reference to FIG. FIG. 1A is a perspective view of the inside of the extrusion container as seen through, and an extrusion nozzle 11 is provided on the side surface of the container 10. A supply port 12 is provided at the rear of the container 10, and from there, the high pressure rubber latex 1 is introduced into the container 10.
3 (fluidized soft elastic material described above) is provided. A twisted yarn 15 (fibrous wire) serving as a core material is wound and stored in a reel 16 inside the container 10, and one end of the twisted yarn 15 is drawn out from a nozzle 11 in advance.

In such an apparatus, when the high pressure rubber latex 13 is supplied from the supply port 12, the wire rod 17 whose periphery is covered with the rubber latex is extruded from the nozzle 11. The extruded wire 17 is
As shown in FIG. 1B, after passing through the drying chamber 18, it is wound by the winding reel 19 to complete the soft wire. In addition, when the use is determined to be a short wire such as a brush wire, the wire may be immediately cut into pieces each having a predetermined length without being wound after drying.

FIG. 2 shows a soft wire produced by the apparatus shown in FIG. Although the nozzle 11 is circular in FIG. 1A, the soft wire produced by this is as shown in FIG. However, by making the shape of the nozzle 11 rectangular, star-shaped or the like, a soft wire 20 having a deformed cross section (particularly, the rubber coating 22) is manufactured as shown in FIGS. 2B to 2E. You can also do it. In any of the cross-sectional shapes, since the twisted yarn 15 is previously immersed in the rubber latex inside the extrusion container 10 in the above-described manufacturing method, the rubber latex enters even a narrow gap between the twisted yarns. Therefore, after the rubber latex is dried and becomes the rubber coating 22, the soft wire material 20 is produced by the anchor effect of the rubber 22 that has entered the gap between the twisted yarns 21.
The rubber layer on the surface of is firmly fixed to the twisted yarn 21, which is the core material.

The soft wire manufactured by the manufacturing method of the above embodiment can be made into a wire for a brush by making the nozzle 11 relatively small (for example, about 1 to 5 mm) and relatively large ( For example, by setting the length to about 5 to 30 mm), the rope can be used for various purposes.

As the twisted yarn 21 serving as the core material of the soft wire 20, in addition to ordinary natural fibers, synthetic fibers or yarns or strings produced by blending them, carbon fiber, Kevlar (trademark), ceramic fiber, metal Twisted yarns using high strength fibers such as fibers can also be used. Depending on the combination of a certain type of fiber and a certain type of rubber latex, the compatibility with the rubber latex may not be good, but in such a case, the twisted yarn is previously impregnated with an affinity agent that mediates the two. Alternatively, it may be soaked in rubber latex.

As a material of the rubber coating 22, it is desirable to use rubber having a relatively high friction coefficient. Examples thereof include synthetic rubbers such as polychloroprene = CR, butadiene acrylonitrile copolymer = NBR, hexafluoropropene vinylidene fluoride copolymer = FPM, styrene-butadiene rubber = SBR, and natural rubber. Further, not only rubber but also soft elastic material to be arranged around the soft wire 20 is used.
Synthetic resin emulsion such as vinyl acetate, acrylic, PVA and vinylidene chloride, thermoplastic polymer such as EVA, polyurethane and PVC, thermosetting polymer such as urethane and epoxy, softening with liquid resin material such as thiochol and acrylic ester. Elastic materials can also be used.

Further, by adding a foaming agent to the soft elastic material, extruding, foaming and solidifying, a soft wire material having a higher friction coefficient can be obtained.

In the case of producing a brush wire, an antistatic agent such as carbon powder or an antibacterial agent such as boric acid for preventing electrification caused by rubbing a bottle with a fluidized soft elastic material. May be added as appropriate. Further, in order to increase the physical peeling force due to friction with the label or the adhesive, fine particles of the abrasive may be mixed in the resin. As the abrasive, fine particles of silicon carbide, alumina, silicon oxide or the like can be used. The size of these powder particles is 1 μm depending on the allowable depth of flaws such as containers and products rubbed with a brush.
Set appropriately within about 1 mm. An example of these mixing ratios is as follows.

Rubber latex 100 parts Abrasive material 2-30 parts Antistatic agent 0.2-15 parts Antibacterial agent 0.1-5 parts

When using a soft wire as a rope, an antistatic agent or an antibacterial agent may be added to the soft elastic material forming the periphery.

An example of the second method of the present invention will now be described. In this method, first, a woven or non-woven fabric which is a sheet-like fibrous body is immersed in a container filled with fluidized soft elastic material such as rubber latex as described above, or the surface is coated with the fluidized soft elastic material. Thus, as shown in FIG. 3A, the fluidized soft elastic material 52 is coated on both sides of the woven fabric 51 and the like. At this time, the woven cloth 5 covered with the fluidized soft elastic material 52
Alternatively, the soft elastic material 52 may be sufficiently impregnated into the woven fabric 51 or the like by once rolling 1 or the like, and then the fluidized soft elastic material 52 may be thickly coated again.

The fluidized soft elastic material 52 which is impregnated into the woven cloth 51 and the like in this manner is subjected to a solidification treatment by heating or the like, whereby the sheet-shaped composite 50 is completed. As shown in FIG. 3 (b), this is cut into a string shape to obtain a soft wire material 53 having a square or rectangular cross section.

In the case of the present embodiment, as the sheet fibrous body 51, paper can be used in addition to the above woven fabric and non-woven fabric. Further, as the fibers constituting the woven cloth and the non-woven cloth, any of the fibers described in the first embodiment can be used, and the soft elastic material 52 can also be the same as the above.

An embodiment of the third method of the present invention will now be described. The method of the present embodiment is a combination of the method of the first embodiment and the method of the second embodiment, and the sheet-like fibrous body 51 used in the second embodiment is extruded in the first embodiment. The sheet-shaped composite body 50 is obtained by extruding it together with the fluidized soft elastic material 52 through an elongated extrusion hole (slit) by an apparatus. Therefore, the materials of the sheet-like fibrous body 51 and the soft elastic body 52 are the first and the second.
What was described in the Example can be used as it is. The sheet-shaped composite 50 extruded in this manner is shown in FIG.
It is the same as that shown in (a). Therefore, a soft wire material similar to that described above can be obtained by cutting it into a slender shape as shown in FIG. 3 (b).

Also in the method of this embodiment, the extrusion slit is not a simple elongated rectangular shape but a deformed shape such as a corrugated shape or a sawtooth shape, and as shown in FIG. A soft wire whose cross-sectional shape changes in the longitudinal direction can be obtained.

As described above, the soft wire produced by the method of the present invention can be used for various purposes such as brush wire, packing, and climbing rope. For example, when it is used as a brush wire, it does not fall off from the brush immediately after cutting like a conventional brush wire made only of rubber or plastic. Becomes Therefore, while the brush is rotating, the portion beyond the cutting portion continues to rub the surface of the bottle or the like even after that, and does not reduce the cleaning action of the container or the like. In addition, when the cross section of the wire is rectangular or star-shaped, the ridgeline enhances the scraping action of the label and adhesive, so the brush with the hair implanted on it shows a stronger cleaning action. To do.

When used as a packing rope, since the soft elastic material on the surface causes a large friction with the baggage, the rope will not be displaced by a slight vibration, and even if the optimum loading cannot be carried out, It becomes a rope that can firmly hold luggage. Further, even in a portion hitting a sharp corner of a hard baggage, the soft elastic material on the outer circumference of the rope softly covers the corner, so that the rope is not worn out by vibration or the like. Therefore, the rope manufactured by the method according to the present invention is suitable for climbing.

[0033]

According to the method for manufacturing a soft wire material by simultaneous extrusion according to the present invention, soft wire materials having various sectional shapes can be manufactured by arbitrarily setting the shapes of the extrusion nozzle and the slit. Therefore, when it is used as a brush wire, the effect of scraping off the label or adhesive on the surface of the container or the like becomes stronger. Also, when it is used as a rope for packing, the friction with the luggage becomes larger,
It will be a rope that can always hold the luggage firmly.
Further, also in the method for manufacturing a soft wire rod by cutting out from the sheet-shaped composite according to the present invention, since the cross section of the soft wire rod is rectangular, the ridgeline increases friction, and the same effect as described above can be obtained.
