SOLUTION: To a manifold 2 provided on a spray material feed part 11 of a spray gun body 1, a spray material feed hose 21 is connected, and also an agitation propeller 23 rotated by a motor 22 with a speed reducer is installed in the manifold 2. And in the case a spray gun for a multicolored pattern is used, when gel coat resins of different colors are fed to the manifold 2 by spray material feed hoses 21, 21, the gel coat resins of different colors are agitated by the agitation propeller 23, and the agitated gel coat resin is fed to the spray gun body 1 through a connecting pipe 24 and is jetted from a jetting part 6 at the tip of the spay gun body 1 to apply a multicolored pattern having desired, complicated feeling to the surface of object FRP half-finished goods.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spray gun for a multicolor pattern, which is suitable for applying a multicolor pattern using a plurality of types of spray materials such as paints and gel coat resins.

[0002]

2. Description of the Related Art Conventionally, for example, Japanese Patent Application Laid-Open No. 3-232560.
As described in Japanese Unexamined Patent Publication (Kokai) No. H10-207, a plurality of types of spray materials are individually supplied to a spray gun through a flow path for individually introducing the spray materials in a plurality of tanks, and the spray materials are individually provided. 2. Description of the Related Art A spray gun is known in which a multicolor pattern is formed by individually jetting with a nozzle.

Further, as described in, for example, Japanese Patent Application Laid-Open No. 4-330956, a manifold is provided by a flow path for individually introducing spray materials in a plurality of tanks for individually storing a plurality of types of spray materials. A spray gun is known in which a multi-color pattern is formed by supplying a spray raw material from a nozzle by supplying the spray material through a nozzle.

[0004]

However, in such a conventional spray gun for a multicolor pattern, when the size of the spray material is relatively large, there is a limit to the degree of mixing between the various spray materials. Spray raw material particles may be applied as they are without being mixed,
There was a problem that the texture of the multicolor pattern was limited to a monotonous one.

The present invention has been made in view of such problems in the conventional spray gun for a multicolor pattern, and an object of the present invention is to solve the above-mentioned problems and to make various types of spray raw materials compatible with each other. The object of the present invention is to provide a spray gun for a multicolor pattern, which can obtain a multicolor pattern having a texture that could not be obtained conventionally by mixing.

[0006]

In order to achieve the above object, a spray gun for a multicolor pattern according to the first aspect of the present invention supplies a plurality of types of spray materials into a spray gun body for a multicolor pattern. Therefore, in a spray gun in which a manifold is provided in a spray material supply unit, a stirring propeller is provided in the manifold, and a plurality of types of spray materials in the manifold are stirred by the stirring propeller. Things.

In the present invention, the stirring propeller includes:
Use of motors with transmissions, impeller motors, servo motors, etc. that can change the number of rotations,
This is preferable because the degree of stirring of the spray material can be adjusted.

[Operation] In the spray gun for a multicolor pattern of the present invention, a stirring propeller is provided in the manifold.
Since a plurality of types of spray materials in the manifold are agitated by the agitation propeller, the plurality of types of spray materials are sufficiently agitated by being agitated by the agitation propeller.

[0009]

Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an explanatory view showing an example of the multicolor pattern spray gun of the present invention, and FIG. 2 is an enlarged sectional view of a manifold 2.

In FIG. 1, reference numeral 1 denotes a spray gun main body;
Reference numeral denotes a manifold provided in the spray material supply unit 11 of the spray gun body 1, reference numeral 21 denotes a spray material supply hose, reference numeral 22 denotes a motor with a transmission provided in the manifold 2, reference numeral 221 denotes electric wires, and reference numeral 3 denotes the spray gun main body 1. , 4 is an ejection amount adjusting section provided on the spray gun main body 1, 5 is a compressed air introducing section provided on a handle of the spray gun main body 1, and 6 is provided on a tip of the spray gun main body 1. Eruption part.

As shown in FIG. 2, a stirring propeller 23 is provided on the manifold 2, and the stirring propeller 23 is driven and rotated by a motor 22 having a transmission. In FIG. 2, reference numeral 24 denotes a connecting pipe provided between the manifold 2 and the spray material supply unit 11 of the spray gun main body 1, and reference numeral 25 denotes a connecting pipe provided between the shaft 231 of the stirring propeller 23 and the bottom plate 26 of the manifold 2. It is the packing which was done.

The spray gun for a multicolor pattern of the present invention shown in FIGS. 1 and 2 has such a structure.
When gel coat resins of different colors are supplied to the manifold 2 by the spray raw material supply hoses 21, 21, the gel coat resins of different colors are stirred by the stirring propeller 23,
The agitated gel coat resin is supplied to the spray gun main body 1 via the connecting pipe 24, and is jetted from the jetting portion 6 at the tip of the spray gun main body 1, so that the surface of the target FRP semi-finished product has a desired complex texture. Color patterns can be applied.

Although the embodiment of the present invention has been described with reference to the drawings, the configuration of the present invention is not limited to the illustrated embodiment, and design changes within the scope of the present invention are included in the present invention. It is.

For example, instead of using a multicolor gel coat resin as in the illustrated embodiment, a multicolor paint may be used.

[0015]

According to the spray gun for a multicolor pattern of the present invention, since a plurality of types of spray materials are sufficiently stirred by being stirred by a stirring propeller, a multicolor pattern having a complicated texture can be applied.
