Description

Line marking device that enables simultaneous spraying of different paints

The present invention relates to a line marking device for painting a line on a flat or wall surface such as a road, and more particularly, the line marking is performed by spraying a liquid paint at room temperature, and different heterogeneous to be applied sequentially. It relates to a line marking device that allows the paint to be applied in one operation to form a line.

In general, the boundary of a roadway is formed or a line is formed for a special purpose so that a user who uses the roadway can recognize the partitioned boundary.

The marking is performed by fusing or spraying paint on the bottom surface of the road for various purposes such as parking division of a parking lot and information displayed on a road, and various equipments have been proposed and used for this line marking.

As a method for marking a line, fusion coating, heating painting, and room temperature painting are widely practiced.

Fusion coating is carried out by fusing epoxy resin etc. as a raw material and melting it at high temperature, and then painting it on the surface to be marked.In the case of heating painting, the coating is heated at a certain temperature to perform painting at a relatively high temperature. In the case of room temperature painting, the coating is dried and dried by spraying the paint onto the marking target surface at room temperature.

In the case of fusion paint or heating paint, the choice of paint is limited, and the disadvantage is that the equipment for painting is large or expensive.

In the case of room temperature painting, it is possible to use the cartridge which is compressed compressed gas and paint or paint is sprayed at room temperature by using liquid paint. Since the painting can be performed, it is a form widely used for general purposes.

In addition, in the marking of lines with special functions such as fluorescent lines, photoluminescent or light reflective lines, special paints are used, and multiple painting operations are required.

Conventional line marking apparatuses apply a white paint for marking a line having the above-mentioned special function, change the paint, reapply a fluorescent paint, and then repeatedly paint using the paint for coating. In general, this work method has the inconvenience of having to reciprocate several times in order to mark the same line as the replacement of paint, which has the disadvantage that the marking time is long.

Therefore, there is a need for a method for solving such problems.

The present invention has been made in order to solve the problems of the prior art described above, to perform the marking by applying a liquid paint at room temperature, and to load several different paints at the same time to be applied in multiple layers at the same time in a single movement In order to provide a line marking device that can perform marking in a short time to the application of a special paint, to adjust the width of the line to be marked, and to perform line marking on the wall as well as the bottom surface.

The objects of the present invention are not limited to the above-mentioned objects, and other objects that are not mentioned will be clearly understood by those skilled in the art from the following description.

222, 224, 226 is due to the characteristics of the present invention, in which a plurality of trays 110 are provided to accommodate different paints, and a line of fluorescent color, a line of stored light or light. In the case of marking a special line such as a line that is reflected, there is an effect of completing the line marking with only a minimum movement of the trolley 100 without multiple round trips.

Specifically, in the case of the special line described above, after the fluorescent color line is marked, for example, the first white line, the fluorescent paint is marked on the area marked with the white line, and then a special paint for coating is applied thereon. Although the process should be performed for this purpose, the inconvenience of having to repeat the marking of the same section several times with several marking apparatuses, but in one embodiment of the present invention, the tray 110 that can accommodate a plurality of different paints is provided. It is provided, and since the paints are discharged from each tray 110 independently and injected from the injection part 220, it has the advantage of facilitating the marking work of the special line.

Therefore, the first spray nozzle 222, the second spray nozzle 224, and the third spray nozzle 226 of the injection part 220 are arranged at a predetermined interval along a traveling direction of the trolley 100 at a predetermined distance. The paints sprayed from the

respective spray nozzles

222, 224, 226 are arranged to form one line.

The guide member 230 is disposed below the housing 210, and is formed to have a lower end adjacent to the ground, and to form a gap such that the paint spraying the gap with the ground does not leak to the outside of the housing 210. do.

In addition, it is provided on both sides of the housing 210 along the traveling direction of the bogie 100, disposed on both sides of the lower side of the injection nozzles (222, 224, 226) of the injection part 220, the width of the left and right width to adjust the injection part ( 220 may be configured to determine the width of the line (P) formed by the paints sprayed vertically downward.

In addition, the guide member 230 should be provided as close to the ground as possible so that the paint is not exposed to the outside and a clean line (P) can be formed, so that interference may occur by touching the ground according to the unevenness or inclination of the ground. .

Therefore, as shown in FIG. 6, the shape may be implemented to be inclined upward toward the front along the traveling direction of the trolley 100 of the guide member 230.

In detail, the front may be formed to have a predetermined curvature based on the moving direction of the bogie 100 and may be configured to more smoothly correspond to an obstacle that may interfere from the front or interference in an uphill terrain.

In addition, the front of the guide member 230 is provided with a guide roller 232 may be configured so that only a minimal impact is applied to the marking unit 200 in the obstacle interference or uphill terrain from the front.

The injection part 220 may further include

injection nozzles

222a, 224a, 226a, which are provided to spray the paint toward the side of the housing 210.

Injection nozzles (222a, 224a, 226a) provided in the side is also provided in a number corresponding to the number of trays 110, the discharge line 130 is independently connected to each tray 110, the user's operation It is provided so as to select and carry out paint spray in the vertical direction or paint spray in the side.

The configuration of the injection part 220 may be used to mark a specific line on a wall of a road or a specific space, as shown in FIG. 5, and move the bogie 100 adjacent to a wall for marking a line. This may be done by manipulating the paints to spray laterally.

In addition, as shown in FIG. 7, in the embodiment of the present invention, the spraying unit 220 is disposed ahead of the spraying part 220 based on the direction in which the marking unit 200 proceeds according to the movement of the trolley 100. Compressed air injection port 240 may be further provided to remove foreign matter by spraying compressed air on the path through which the paint is to be sprayed.

As described above, a preferred embodiment according to the present invention has been described, and the fact that the present invention can be embodied in other specific forms in addition to the above-described embodiments without departing from the spirit or scope thereof has ordinary skill in the art. It is obvious to them. Therefore, the above-described embodiments should be regarded as illustrative rather than restrictive, and thus, the present invention is not limited to the above description and may be modified within the scope of the appended claims and their equivalents.
