Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a resin hose that adds a discrimination function to a base color by a different color scheme.

[0002]

2. Description of the Related Art Conventionally, in a resin hose that connects each flowing liquid to various kinds of conduits in the middle of the conduit for each liquid,
Color-coded connections to the resin hose for each liquid line,
This is used to identify the contents flowing through the pipelines by coloring the resin hose when connecting to a large number of pipelines to prevent connection errors.

When the resin hoses colored for identification are generally manufactured, the resin material is toned in a predetermined amount, so that lots of each toning are produced in large quantities.

That is, a colored resin hose is basically formed by adjusting a transparent resin material to a desired color by a predetermined amount and then molding the hose by an extrusion molding machine. Therefore, it is troublesome to change the color to each color. Since a waste of material occurs, it is necessary to produce a certain amount, and the product is produced as such.

Further, the colored resin hose is heat-treated to be formed as a bent hose corresponding to each pipeline.

[0006]

Conventionally, the resin hose colored for identification is used by identifying the contents flowing in the pipeline by the color of the resin hose so that there is no connection error between the pipelines. When it is produced, it is generally produced in a large amount in a predetermined lot, and the cost is high in a small lot, and the production amount was not suitable.

That is, in the colored resin hose, a transparent resin material is basically toned to a desired color to be molded into a hose, and if the amount is less than a certain amount, the material cost for coloring cannot be used.

Further, when the colored resin hoses produced in such a state are to be prepared for each color, a large amount of resin hoses must be ordered with respect to the amount of resin hoses used, and in recent years it is a large variety of small lots. Didn't follow the flow of.

Further, the colored resin hose is heat-treated to be formed as a bent hose corresponding to each pipe line. When the resin hose is formed by heating, the resin pipe is twisted and fitted into the molding die. However, if it is heated and formed in that state, the twisted strain appears when it is cold and in use, and the formed bent hose cannot be used in a predetermined attached state.

That is, when the resin hose is heat-treated and fitted into the mold, it cannot be discriminated whether it is twisted because it is of a single color, and even if it takes time to carry out the confirmation work during mass production, it still occurs. I was waiting for countermeasures.

[0011]

According to the present invention, firstly, in a transparent or colored resin hose, the transparent or colored hose is formed as a base color and a different color is integrally formed on a predetermined portion. Therefore, it is possible to inexpensively produce a wide variety of colors in a small lot without having to mix a large amount of a desired color in the transparent resin material.

Secondly, by arranging different colors in a linear or discontinuous dotted linear shape, when the resin hose is heated to form a bent hose, the twist is visually observed by the linear color arrangement. It is possible to produce quickly while correcting distortion.

[0013]

BEST MODE FOR CARRYING OUT THE INVENTION The resin hose having the identification function of the present invention is transparent or colored as a base color, and on the surface side of the resin hose, a single color or a plurality of colors are integrally and linearly or intermittently combined with different colors. And mold it into a hose.

The resin hose formed as described above is fitted into a predetermined mold without distortion and heat-treated to form a bent hose.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. In FIG. 1, 1 is a resin hose having an identification function, and the resin hose 1 having the identification function is provided on the surface side of a transparent resin hose 2. Identification linear bodies 3 of different colors are arranged in a straight line in the longitudinal direction with respect to the transparent resin hose 2.

In FIG. 2, the bending hose 6 is formed by fitting the resin hose 1 having the above-mentioned identification function into the die groove 5 of the molding die 4 and heat-treating it.

However, in the production of the resin hose 1 having the identification function, when a transparent resin material as an example is used as a base material and extrusion molding is performed by an extrusion molding machine, a different type is formed at the tip of the extrusion molding machine. By extruding the identification color material at the same time, different colors can be colored on the surface side of the resin hose 1, and the resin hose 1 having an identification function can be molded by continuously arranging the colors in a straight line in the longitudinal direction. .

Further, the different color materials for identification are used in a small amount as compared with the base material, and a general-purpose ready-made color resin material is used without particular color matching.

Then, in the resin hose 1 having the identification function molded as described above, the liquids flowing in the various types of conduits are respectively color-coded and connected to the respective liquid conduits. At that time, the conduits are connected. The contents flowing through the identification line member 3 of the resin hose 1
By identifying the contents according to the color of, the connection mistake between the pipelines is prevented.

Further, when the resin hose 1 having the identification function formed as described above is connected between a large number of pipelines, the resin hose 1 having the identification function is provided in an apparatus having a large number of pipelines.
However, it is necessary to bend it into a predetermined shape because it is necessary to connect the pipes regularly so as not to become complicated.

Therefore, as shown in FIG. 2, the resin hose 1 having an identification function is fitted into the die groove 5 of the molding die 4 formed in a predetermined bending shape without distortion, and is heat-treated and bent. The hose 6 is formed.

When the resin hose 1 is fitted into the mold groove 5 of the molding die 4 to form the bending hose 6, it is fitted while checking the twisting of the resin hose 1 by the linear identification color body 3. The bent hose 6 having a predetermined shape is formed by heating, heating, and cooling.

That is, as shown in another embodiment shown in FIG. 3 in which the identification hose 6a is bent, the bending hose 6a is distorted and the identification linear member 3 is twisted. In addition to the process, in the example of the three-dimensional bending hose 6a, it occurs when the bending hose 6a is bent while the resin hose 1 is twisted, and when the pipe is connected, the bending hose 6a is adjacent and twisted. The other bending hose 6 is affected.

Therefore, as shown in FIG. 3, the bending hose 6 is
In order to eliminate the distortion of “a”, when the resin hose 1 shown in FIG. 2 is fitted into the mold groove 5 of the molding die 4, the identification linear body 3 is visually checked in a straight line state, and heat treatment is performed. Thus, the resin hose 1 can be formed into the bent hose 6 without distortion.

Although the identification linear body 3 of the resin hose 1 having the identification function is formed in a single straight line, a plurality of different identification color materials are extruded simultaneously at the tip of the extrusion molding machine. A plurality of identification linear bodies 3 may be colored, and it is also preferable that the identification linear bodies 3 are intermittently extruded to form a dotted straight line.

Further, the identification linear body 3 is circulated on the surface side of the transparent resin hose 2 and provided in a ring shape at a predetermined interval, and one portion of the ring shape is cut out, and the cutout portions are arranged linearly for identification. A linear body may be used, but the illustration is omitted.

Further, in this embodiment, the bending hose 6 is formed by the molding die 4, but it is also preferable to use other dedicated jigs when forming a three-dimensional shape or the like, but the illustration is omitted.

[0028]

The present invention is embodied in the form as described above, and in particular, in a transparent or colored resin hose, the transparent or colored hose is used as a base color and a different color is integrally arranged in a predetermined portion. Since it is molded, when producing a resin hose having an identification function by color coding, it is not necessary to mix a large amount of a desired color in the resin material, and by using a ready-made color resin material,
It is possible to produce a small number of resin hoses with a multi-product identification function, thus reducing production costs.

Further, since the resin hoses are colored in different colors in a linear or discontinuous dotted linear shape, when the resin hose is heat-treated to form a bent hose, the molding die 4 is formed by the linear coloring. When it is fitted in the mold groove 5, the twist can be visually corrected, so that the bending hose 6 can be easily produced quickly without distortion, defective products can be reduced and reliability can be increased, and the production cost can be reduced. Therefore, the present invention has a great effect in practical use.
