TECHNICAL FIELD OF THE INVENTION
The present invention relates to an injection-type road marking application method and an injection-type road marking application device.
[0002]
[Prior art]
As a conventional injection type road marking application device, for example, there is one as shown in FIG. (See JP-A-55-155756)
That is, the two cylindrical rotating bodies 21 and 22 spaced apart from the ground GL are arranged in parallel and equidistantly with respect to the ground. The two cylindrical rotary bodies 21 and 22 are rotated inward by a power (not shown) while contacting the generatrix of the two cylindrical rotary bodies 21 and 22 in the directions indicated by arrows, respectively. Reference numeral 23 denotes an application material tank, and reference numeral 24 denotes a downflow cock disposed between the application material tank 23 and the cylindrical rotating bodies 21 and 22. Reference numerals 25 and 25a denote opening / closing shutters that open and close horizontally in relation to the down cock 24.
[0003]
In such a device, when the down cock 24 is opened, the open / close shutters 25 and 25a are also opened horizontally, and the coating material in the coating material tank 23 is supplied to the coating material outlet 23a provided in the lower portion of the coating material tank 23. At the same time, it flows down in the inscribed direction of the two cylindrical rotating bodies 21 and 22 immediately below, and at the same time, is atomized by the centrifugal force and repulsive force due to the rotation of the cylindrical rotating body 21 in the downward direction, and is sprayed on the road surface of the ground GL. , Road marking painting 26 is performed.
When the down cock 24 is closed, the open / close shutters 25 and 25a are also closed. Therefore, the outflow of the coating material is immediately stopped, and the road marking painting can be stopped.
[0004]
Further, as another conventional injection type road marking application device, as shown in FIG. 9, two cylindrical rotating bodies 21, 21a rotatably supported by both side plates 27, 27a and separated from the ground are mounted on a road surface GL. With the opening and closing operation of the flow-down cock 24 with respect to the coating material outlet 24 provided at the lower part of the coating material tank 23 in parallel with and equidistant from the coating material tank 23, the inner surfaces of the rotating bodies 21 and 21a are directed downward while contacting the generatrix. The coating material in the coating material tank 23 is caused to flow into the contact point side while rotating in the tangential direction, and at least the lower portions of both the rotating bodies 21 and 21a are each provided with four burners as shown in FIG. 28 (the number changes depending on the size of the marking line width), and the coating material flowing into the contact side is atomized by centrifugal force and repulsive force due to the rotation of the two rotating bodies 21 and 21a, and is atomized on the road surface GL on the ground. Inject Is obtained to perform the road markings painted 26 as shown in FIG. 10.
[0005]
[Problems to be solved by the invention]
In the former conventional device, since the opening and closing shutters 25 and 25a linked to the down cock 24 operate to open and close horizontally, the coating material is sprayed onto the road surface of the ground GL from between the two cylindrical rotating bodies 21 and 22. In this case, since the coating material adheres to the opening / closing shutters 25 and 25a, there is a possibility that the coating material hangs down and stains the painted road marking surface during construction. Further, there is a problem that the coating material adhering to the opening and closing shutters 25 and 25a is solidified, and the yield is low.
Also, in order to open and close the opening and closing shutters 25 and 25a widely and horizontally, a large operating force is required, and the structure becomes large and the cost is increased.
[0006]
Further, in the latter conventional apparatus, there is a problem that the flow of the coating material is poor and the upper corner portions 26a on both sides in the cross section of the road marking coating 26 are chipped as shown in FIG.
[0007]
[Means for Solving the Problems]
An injection type road marking coating device of the present invention aims to solve the above-mentioned problems, and a hopper for storing the coating material, and a pair of a hopper that sprays the coating material downward and inwardly while rotating the coating material inward. Injection type road sign provided with a rotating body, an application material outlet shutter provided in the hopper, and an application material blocking shutter for blocking the application material ejected from the rotating body at a position below the both rotating bodies. In the coating device, a burner for uniformly warming the rotating body is provided below the rotating body, and burners are provided above both sides of the rotating body, and the coating material blocking shutter is connected to one side of the rotating body. The coating material shut-off shutter has a width substantially equal to the axial length of both rotators, and is rotatably disposed in a range between the portion and the lower position. At the required position above the side Attached to a pivot arm provided with a point, and the pivot arm is inclined or almost upright with respect to the ground when the coating material blocking shutter is opened and rotated, and when the coating material blocking shutter is closed and rotated, It is characterized by being bent at an acute angle of about 60 degrees, which is almost parallel to the ground .
