Description

[Detailed Description of the Invention] This invention relates to a road paint application device for drawing marking lines such as no-extrusion lines on the road surface.

Among the various signs displayed on road surfaces, the no-extrusion line has traditionally been simply indicated by one or two yellow lines painted at intervals, but the yellow color has the risk of becoming less noticeable when it fades. Therefore, it is better to display a yellow line with a white line in between, because the yellow of the line stands out more clearly in contrast with the white line, and it is easier to identify, especially at night. , those painted yellow came to be adopted.

However, in order to apply the above-mentioned yellow, white, and yellow separately using a conventional coating device, the device must be moved three times for each color, and it also requires a great deal of skill to coat each color layer correctly adjacent to each other. It takes.

In other words, in the case of welding type paints, each coated layer has a considerable thickness, so if adjacent color layers partially overlap, that part will bulge, and when separated, gaps will be created, resulting in unsightly results. Moreover, if one side of the coating device rides on the previously applied coating layer, the device will tilt, making it difficult to reliably apply adjacent coatings.

In addition, it was necessary to use two coating devices for the white and yellow paints, or to use one coating device, which had to be thoroughly cleaned each time the color was changed.

In contrast, the coating device of this invention divides the coating material hopper into multiple chambers, for example, three chambers, through partition walls, and provides a shutter for each chamber so that a fixed amount of coating material can be simultaneously discharged from each chamber. It is composed of

The interior is formed into a plurality (three in the figure) of compartments 3 through....

At the bottom of this coating material hopper 1, there is a round bar-shaped shutter 4.
is inserted through the opening/closing lever 5 and can be rotated by an opening/closing lever 5 attached to one end.

This shutter 4 is provided with a transparent hole "JL6" extending through it corresponding to the bottom of each compartment 3. can flow out.

By moving the coating material hopper 1 over a desired road surface in this manner, a plurality of coating layers can be formed adjacent to each other.

FIG. 3 shows various modifications of the shutter. In FIG. 3A, each shutter 4 is made into a rod-like shape 4' having an inverted triangular cross section, and is opened and closed by vertical movement.

In Figure B, it is formed as a horizontal plate 4'' that is movable back and forth, and in Figure C, it is formed as a swingable vertical plate 4'' whose upper end is pivoted.

These shutters 4/, 4//, and 4/II are all provided for each compartment, and are connected by appropriate connecting rods or the like and operated simultaneously.

4A and 4B show the case where the coating material is injected via rolls, and one roll rotates below the coating material hopper 1 (in the case of FIG. 4A), or one roll rotates inward from each other. roll 7
', 7' are provided (in the case of FIG. 4B) to ensure uniform coating, and these rolls 7, or 7', 7' are connected to shafts 8, or 8', 8'. and rotated by appropriate power.

The coating material exits the shutter 4 and is spray-sprayed by the centrifugal force of the rolls so that it is evenly coated.

9 is a cover. In this case, the shutter 4 is as shown in FIG.
In B, a round bar shape is shown, but it may also be the one shown on each side shown in FIG.

As described above, this invention enables the formation of adjacent coating layers of multiple colors in one operation using one device, and the operation is extremely efficient without requiring any skill. be able to.
