Abstract

PROBLEM TO BE SOLVED: To smoothly spray paint on a road surface and retain uniformity of paint in a paint container tank by providing a rotary body used for agitation for paint and spray thereof in common in the paint container tank and spraying the paint while agitating the paint in the tank. SOLUTION: A rotary body 2 used for agitating and spraying paint in common is rotated in the direction shown by an arrow mark, and when an opening/ closing shutter 4 is opened, the paint 6 in a paint container tank 1 is sprayed onto a road surface 7 from a paint jetting opening 3 while it is agitated by the rotary body 2 used for agitating and spraying the paint in common to apply the paint 6 for marks. When the shutter is closed, it ceases to spray the paint. In this way, the paint can be smoothly sprayed onto a road surface and the paint can be homogeneously kept in the tank. Since a primary shutter partitioning a paint container tank and a spraying rotary body, which conventional devices have, is not required at all, the structure can be also simplified.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a center line,
The present invention relates to a method and an apparatus for applying a side line, a zebra line and other various jetting road markings.

2. Description of the Related Art Conventionally, as an injection type road sign coating method and apparatus, there are Japanese Patent Application Laid-Open Nos. 54-62624 and 59-147669.

[0003]

However, in each of the prior arts described above, since the rotating body for injecting the paint on the road surface is disposed outside the paint containing tank, the paint from the paint containing tank to the rotating body can be smoothly removed. In addition to the problem that the supply of the paint is difficult and therefore the spraying of the paint by the rotating body on the road surface is not performed smoothly, and in order to maintain the uniformity of the paint in the paint storage tank,
There was a problem that a stirring means had to be separately provided in the paint storage tank.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems, and to rotate a paint agitating / injecting rotary body in a tank containing a paint to agitate the paint in the tank and open and close the tank. Road marking is performed by operating the shutter to spray and stop the paint. One paint agitating / spraying rotator is provided in the paint containing tank, and an opening / closing shutter is provided at a paint spray opening of the paint containing tank, and the paint in the paint containing tank is rotated by rotation of the paint agitating / spraying rotation. And the road is marked by injecting and stopping the paint by opening and closing the opening / closing shutter. In addition to disposing a pair of paint agitating and spraying rotators in the paint containing tank and providing a pair of open / close shutters at a paint spray opening of the paint containing tank, the paint agitating and spraying rotation in the paint containing tank is performed by rotation of the paint agitating and spraying rotation. The method is characterized in that the paint is agitated, and the paint is injected and stopped by opening and closing the pair of opening and closing shutters to perform road marking.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. 1 and 2 are schematic side views schematically showing a preferred embodiment of an injection type road marking application device according to the present invention using one paint agitating / injection rotating body, and FIGS. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic side view schematically showing a preferred embodiment of an injection-type road sign application device according to the present invention using a paint agitating and injection rotating body.

In each of the drawings, reference numeral 1 denotes a paint storage tank, and 2 denotes a paint agitating / spraying rotator provided in the paint storage tank 1 so as to be rotated by an appropriate rotating device (not shown). The material, shape, and size are arbitrary, and those used in a conventionally well-known jet-type road sign coating device are used. Reference numeral 3 denotes a paint injection port provided in a lower portion of the paint storage tank 1, and reference numeral 4 denotes an opening / closing shutter, which is opened / closed by a suitable opening / closing device, not shown. Reference numeral 5 denotes a perforated cover body provided as needed in the paint storage tank 1 to improve the agitation of the paint 6 by the paint agitating and jetting rotary body 2. The perforated cover body 5 may be one without holes. 7 is a road surface and 8 is a spray paint.

Next, the operation will be described. In the state shown in FIG. 1, the paint agitating / spraying rotator 2 is rotated in the direction of the arrow, and the opening / closing shutter 4 is opened as shown in FIG.
While the paint 6 in the inside is stirred by the paint stirring and spraying rotary body 2, the paint 6 is sprayed from the paint outlet 3 onto the road surface 7,
The sign application of the paint 6 is performed. When the opening / closing shutter 4 is closed, the spraying of the paint 6 is stopped. In the case shown in FIG. 3, the paint agitating / spraying rotators 2 and 2 are rotated in the directions of arrows a and b, respectively, and the opening and closing shutters 4 and 4 are opened as shown in FIG. Is stirred by the paint agitating / injecting rotators 2 and 2 while the paint
Is sprayed onto the road surface 7 to perform the marking application of the paint 6. If the shutters 4 and 4 are closed, the paint 6
Injection stops.

[0008]

As described above, according to the present invention,
A rotating body that is used for both agitation and spraying of paint is provided in the paint storage tank and sprays while stirring the paint in the paint storage tank to perform road marking. Not only can be performed smoothly, but also the uniformity of the paint in the paint storage tank can be maintained, and the primary partitioning between the paint storage tank and the injection rotating body as in the conventional apparatus can be performed. Since a shutter is not required at all, there are various effects such as the structure can be significantly simplified.
