DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an injection type road marking coating apparatus which can apply a broken road marking with a uniform flow rate of a coating material.

[0002]

2. Description of the Related Art As a conventional injection type road marking coating apparatus of this type, a known one is shown in FIG. 3, for example. (See, for example, Japanese Patent Application Laid-Open No. 55-155756) That is, the two cylindrical rotating bodies 31 and 32 separated from the ground GL are arranged in parallel with the ground and at the same distance from each other. The two cylindrical rotating bodies 31 and 32 are driven by power (not shown).
Each of them rotates in the inscribed direction downward while contacting the generatrix of the two cylindrical rotating bodies 31 and 32 in the directions indicated by arrows. Three
3 is a coating material tank, 34 is this coating material tank 33
And a down-flow cock disposed between the cylindrical rotating bodies 31 and 32. Reference numerals 35 and 35a denote opening / closing shutters that open and close horizontally in relation to the down cock 34.

In such an apparatus, the down cock 34
Is opened, the opening / closing shutters 35 and 35a are also opened horizontally, so that the coating material in the coating material tank 33 can be rotated by the two cylindrical rotating bodies 31, just below the coating material outlet 33a provided in the lower portion of the coating material tank 33. At the same time as flowing down in the inscribed direction of 32
The road sign painting 36 is performed by atomizing downwardly by centrifugal force and repulsive force due to the rotation of the cylindrical rotating body 31 and spraying the atomized air onto the road surface of the ground GL. Further, when the down cock 34 is closed, the open / close shutters 35 and 35a are also closed, so that the outflow of the coating material is immediately stopped, and the road marking painting can be stopped.

[0004]

As described above, in the conventional injection type road marking coating apparatus, the coating material from the coating material tank 33 is sprayed by the two cylindrical rotating bodies 31 and 32, and is sprayed on the road surface of the ground GL. We perform road marking painting 36,
Since the amount of the coating material in the coating material tank 33 decreases with each injection, the pressure of the coating material outlet 33a changes, and the amount of the coating material flowing out is not constant. There was a problem that was not performed.

Further, since the opening and closing shutters 35 and 35a linked to the down cock 34 are opened and closed horizontally, when the coating material is sprayed from between the two cylindrical rotating bodies 31 and 32 onto the road surface of the ground GL, the opening and closing shutter 35 and 35a are opened. , 35a, there is a risk that this coating material hangs down and stains the painted road marking surface during construction. Further, there is a problem that the coating material adhered to the opening / closing shutters 35, 35a is solidified, and the yield is low. Also, in order to open and close the opening and closing shutters 35 and 35a horizontally, a large operating force is required, and there is a problem that the structure is large and the cost is high. In order to finish the front and rear ends of the road marking paint 36 neatly,
A tape was stuck to the front and rear ends and jetted, and then the tape was peeled off.

You. At this time, a predetermined amount of the coating material is delivered from the inside of the coating material storage case 11 to the hopper 3 through the coating material delivery port 11a by the coating material delivery means 13.

During the application of the road marking coating, the coating material receiving plate 20 for preventing the coating material from dripping and the coating material receiving plate 22 for cutting the road marking tip are separated from the lower position on both sides of both the rotating bodies 1 and 2, respectively. The vehicle is lifted to a position, and a road marking line is applied to the ground GL in accordance with the movement of the device in the traveling direction, following the road marking having a clean tip shape.

At the end of the road sign application with the application material discharge port shutter 7 closed, the two rotating bodies 1, 2 of the application material 4
Since the inflow to the side is cut off and the injection by the two rotating bodies 1 and 2 is cut off, the discharge of the coating material 4 is immediately stopped, and the road marking painting can be stopped. At this time, since the coating material receiving plate 20 for preventing the coating material sagging and the coating material receiving plate 22 for cutting the road marking tip are lowered to the positions below the rotating bodies 1 and 2 almost simultaneously, The coating material 4 hanging from the coating materials 1 and 2 is received by the coating material receiving plate 20 for preventing the coating material from dripping, and is further received by the coating material receiving plate 22 for cutting off the road marking tip. Therefore, the rear end shape of the road marking line is applied finely on the road surface. During construction, the coating material 4 adhering to the coating material receiving plate 20 for preventing the coating material sagging and the coating material receiving plate 22 for cutting the road marking tip before heat is formed into small tubs by heat and placed in a container 25 before forming the sign. Since it is dropped and a new sign is formed immediately after that, there is no effect on the sign painted surface, and the finish is beautiful.
