Description

  The present invention relates to a method and an apparatus for coating an inner surface of a threading rod, and more particularly to a technique for forming a resin layer for improving the sliding property of a fishing line insertion space inside the rod.

Conventionally, as a threading rod configured as described above, a fishing line is prevented by arranging a spirally formed thread guide member on the inner surface of the rod material to prevent the fishing line from adhering to the inner surface of the rod material. There is one configured to guide lightly (for example, Patent Document 1).
JP-A-1-304836

  Here, when thinking about threading rods, this type of kite eliminates thread entanglement in the guide and makes the kite operation easier compared to a kit with a yarn guide on the outer surface of the kite. In the technique of Patent Document 1 described above, even when a fishing line in a wet state passes through the inside of the fishing rod, the fishing line is prevented from adhering to the inner surface of the fishing rod. It has a good aspect of sending smoothly.

  However, since the technology of Patent Document 1 has a structure in which a thread guide member manufactured separately from the saddle material is inserted into the saddle material, it takes time to manufacture the yarn guide member, and the thread guide member is used as the saddle material. There is room for improvement because it takes time and effort to insert it into the inner surface.

  In order to eliminate this inconvenience, it is preferable to apply a fluorine resin such as a polymer of trifluoroethylene chloride and a polymer of tetrafluoroethylene having good water repellency and a low coefficient of friction by means such as coating. Although it is conceivable to form the resin on the inner surface, this type of resin is not very good in adhesiveness with other resins and has low feasibility.

  An object of the present invention is to provide an inner surface coating method for a through rod that forms a resin layer for smoothly guiding a fishing line without impairing the conventional good surface of preventing the fishing line from adhering to the inner surface of the rod material. The reason is to rationally configure the device.

  The first feature of the present invention is that an inner surface of a threaded rod that allows a fishing line (6) to be inserted into an inner space of a rod (R) that is formed into a cylindrical shape by winding a prepreg impregnated with resin in high-strength fibers. In the coating method, a mixture of fluorine resin particles (8) and a resin coating material (9) is applied to the inside of the rod (R) on the entire inner surface through which the fishing line (6) of the rod (R) passes. The resin layer (P) is formed by the resin coating material (9) by supplying air to the inner surface of the brazing material (R) and drying it, thereby forming the resin layer (P). ) Is exposed to the surface of the above-mentioned fluororesin particles (8), and their functions and effects are as follows.

[Action]
When the first and second features are configured as shown in FIGS. 1 to 5, for example, a mixture of the fluororesin particles 8 and the resin coating material 9 with respect to the inner surface of the brazing material R at the time of producing the through-through ridge. The resin layer P is formed by applying and drying, and the resin layer P adheres to the brazing material R like a fluorine resin such as a polymer of trifluoroethylene chloride or tetrafluoroethylene. The resin layer P can be used as the base material R because the resin coating material 9 having good adhesiveness to the base material such as polyurethane can be used as a main component. On the other hand, it is formed in a state of being firmly bonded. Further, since the fluorine resin particles 8 are exposed on the surface of the resin layer P formed in this way, even if the fishing line 6 in a wet state may come into contact, the good water repellency of the fluorine resin particles 8. As a result, the moisture is formed into independent water droplets and the spread is prevented, so that the attachment of the fishing line 6 is suppressed, and the resistance during movement of the fishing line 6 is reduced by the low friction coefficient of the fluorine resin particles 8. .

  Further, for example, when configured as shown in FIG. 7 to FIG. 9, when manufacturing the punch through, a film of ultrahigh molecular weight polyethylene 12 on which an adhesive layer 14 has been previously formed is wound around the core material 13, and this adhesive layer 14 A prepreg 15 such as a sheet is wound around the outer surface of the sheet, fired, and then the core material 13 is removed, whereby a brazing material R provided with a resin layer Q of ultrahigh molecular weight polyethylene 12 on the inner surface via an adhesive layer 14 is obtained. It will be formed. In addition, since the ultrahigh molecular weight polyethylene 12 having high wear resistance and high lubricity is exposed on the wide inner surface of the resin layer Q formed in this way, the wet fishing line 6 may come into contact with the resin layer Q. Even so, as a result of the water repellency of the resin layer Q being prevented from spreading in the form of independent water droplets, adhesion of the fishing line 6 is suppressed, and furthermore, the fishing line 6 is prevented by the low friction coefficient of the resin layer Q. This reduces the resistance during movement. The ultra high molecular weight polyethylene 12 has a static friction coefficient of about 0.25 and a dynamic friction coefficient of about 0.15.

  That is, according to the present invention, the fishing line 6 can be smoothly guided as in the prior art due to the properties of the fluorine resin particles 8 or the ultrahigh molecular weight polyethylene 12, and at the same time, the fishing line 6 can be moved with a light force. Thus, the resin layers P and Q having good properties are formed by a relatively simple process of coating, or an improvement to the extent that one process is added at the time of manufacturing the brazing material R.

  Therefore, an inner surface coating device for a through rod that can easily form a resin layer that smoothly and lightly guides the fishing line on the inner surface of the rod material without impairing the conventional good surface of preventing the attachment of the fishing line to the inner surface of the rod material In addition, the inner surface coating method for easily manufacturing the through hole is rationally configured.

  A first embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 6, the rod material R of the head rod 1, the intermediate rod 2, and the main rod 3 is configured in a side-by-side configuration, and the fishing reel 5 is mounted on the main rod 3 via the reel seat 4. Constructs a through hole. This threading rod is configured to feed the fishing line 6 from the line insertion hole 7 formed in the middle portion of the main rod 3 through the inner space of each rod material R through the tip of the tip rod 1. In order to smoothly feed the fishing line 6 to the inner space of the material R, as shown in FIG. 1 and FIG. 2, fluorine resin particles 8 made of a polymer of ethylene tetrafluoride are provided on the inner surface of the rod material R. A resin layer P mixed in the coating material 9 is formed.

  This fluorine resin composed of a polymer of ethylene tetrafluoride has a chemical formula of its monomer:

It has a good water repellency and a low coefficient of friction, and even when the wet fishing line 6 comes into contact with the resin layer P, the adhesion of the fishing line 6 to the resin layer P is suppressed and at the same time a low coefficient of friction. Thus, the fishing line 6 can be sent without causing much resistance, and the resin layer P is formed by the following steps.

  This brazing material R is formed by winding a prepreg (not shown) in which high strength fibers such as carbon fiber and glass fiber are impregnated with a resin such as epoxy around a mandrel (not shown) in which aqueous wax is applied as a decentering agent. It is formed into a cylindrical shape by turning and firing, and after this molding, as shown in FIG. 3, the aqueous wax is removed by washing with water, and the oil and fat components are removed by wiping off alcohol.

  Further, the resin layer P is obtained by mixing and dispersing the solid fluorine resin particles 8 in the resin coating material 9 containing a polyurethane resin as a main component, and adding a paint leveling agent so that the coating film surface becomes smooth. This is a mixture, and the particle diameter of the fluorine resin particles 8 is set to about 0.3 μm.

  Next, as shown in FIG. 4, the mixture of the resin coating material 9 from the paint pressure feeding tank 11 pressurized by the compressor 10 is fed from the large diameter side of the brazing material R to the inside of the brazing material R and applied. After that, as shown in FIG. 5, the resin layer P shown in FIG. 2 is formed by supplying air from the compressor 10 and drying in a state where the brazing material R is set in a standing posture. is there.

  And by forming the resin layer P on the inner surface of the rod material R in this way, even if the wet fishing line 6 is sent on the inner surface of each rod material R, the moisture spreads as an independent water droplet. Since the fishing line 6 is prevented from adhering, the fishing rod 6 moves while the fishing line 6 is in strong contact with the inner surface of the tip rod 3, but the fishing line 6 is lightly fed by the low friction coefficient of the fluorine resin particles 8. It will be easy to operate.

  Hereinafter, a second embodiment of the present invention will be described with reference to the drawings. In this embodiment as well, a through rod is formed as in the first embodiment. In this through rod, the inner surface of the rod R is provided on the inner surface of the rod R so that the fishing line 6 can be smoothly fed into the internal space of the rod R. As shown in FIG. 7, a resin layer Q made of ultrahigh molecular weight polyethylene 12 is formed.

  This ultrahigh molecular weight polyethylene 12 has the chemical formula of its monomer

It has a good water repellency and a low coefficient of friction, and even when the wet fishing line 6 comes into contact with the resin layer P, the adhesion of the fishing line 6 to the resin layer P is suppressed and at the same time a low coefficient of friction. Thus, the fishing line 6 can be sent without causing much resistance, and the resin layer Q is formed by the following steps.

  That is, as shown in FIG. 8, a film of ultrahigh molecular weight polyethylene 12 having an adhesive layer 14 formed in advance on a mandrel 13 as a core material is wound with the adhesive layer 14 as an outer surface, and as shown in FIG. As described above, a sheet-like prepreg 15 in which a high-strength fiber such as carbon fiber or glass fiber is impregnated with a resin such as epoxy is wound around the outer surface of the adhesive layer 14, and a heat shrink tape (not shown) ) Is wound and fired, and then the mandrel 13 is pulled out, whereby the brazing material R having the resin layer Q of the ultrahigh molecular weight polyethylene 12 is formed on the inner surface via the adhesive layer 14.

  The film of ultrahigh molecular weight polyethylene 12 is 0.1 to 0.4 millimeters and has a uniform tape-like thickness, and the adhesive layer 14 is an adhesive mainly composed of acrylic resin, synthetic rubber or the like. Good one is used.

[Another embodiment]
In the present invention, any fluorine polymer particles other than the above-described embodiments may be used as the fluorine resin particles, for example, any fluorine-containing olefin polymer such as a fluorine resin composed of a polymer of trifluoroethylene chloride. Various materials such as acrylic resin are also used for the resin coating material.

  In the present invention, the diameter of the fluorine resin particles can be set larger or smaller than 0.3 μm, and particles having different particle diameters can be used in a mixed state.

  In the present invention, when the resin layer is formed, the inner surface of the brazing material is roughened by polishing so that the adhesiveness of the resin layer to the brazing material can be improved.

  Further, in the present invention, it is possible to use an ultra-high molecular weight polyethylene film having a length equal to the total length of the ridges, and it is also possible to form the tape-shaped film described above in a form in which a gap is formed. .
