Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lane marking apparatus and a lane marking apparatus,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lane marking apparatus and method, and more particularly, to a lane marking apparatus having a metering device and a lane marking method.

The lane-painting device is a device that is installed in the vehicle and automatically paints the lane as the vehicle moves.

Conventionally, lanes are painted by melting and applying a thermoplastic resin. However, when the thermoplastic resin is melted to paint the lane, high temperature is required, and when the road surface is frozen as in winter, it is difficult to construct. In addition, the lanes using thermoplastic resin have a problem that the brightness and reflectivity are very low and the life of the product is short.

In order to solve this problem, a method of painting a lane by coating a mixture of various materials has been proposed. One such material is the methyl methacrylate (MMA) series resin. The methyl methacrylate (MMA) series resin has a high life and has a property of curing in a short time. As described above, the methyl methacrylate (MMA) series resin is advantageous in that the curing time is fast, but has a problem that it is difficult to control because the curing time is fast.

For example, in the case of a polytype, a fixed amount is mixed and injected. However, there is a problem that it is difficult to mix a fixed amount and inject. In the case of the multi-liquid type paint, if the quantities are not mixed, there is a problem that the painted lane is defective.

Also, in the process of mixing various materials, the paint may harden and harden, resulting in difficulties in continuous painting or later painting. Particularly, when the material constituting the paint flows backward without moving according to a desired flow, the paint is hardened inside the lane marking apparatus by hardening, which may greatly reduce workability.

The cleaning agent 310a is supplied to the quantitative mixing valve 140, the paint mixer 120, the paint sprayer 130, and the like in the resting stage where the paint composition 120a is not sprayed, ), The second subject 112a, the curing agent 114a, and the like. The hardening is caused by the first main body 111a, the second main body 112a, and the hardening agent 114a remaining in the quantitative mixing valve 140, the paint mixer 120, the paint sprayer 130, .

The pressure supply unit 400 is connected to the paint storage unit 110, the bead storage unit 210, and the detergent storage unit 310, and supplies the pressure to the material accommodated in the paint storage unit 110, the bead storage unit 210, The pressure supply unit 400 includes a compressor 410 and various pumps connected to the compressor 410 and providing pressure to the paint storage unit 110, the bead storage unit 210, and the detergent storage unit 310 412, 414, 424, 434).

In this embodiment, one compressor 410 is connected to the various pumps 412, 414, 424, 434, and 144, respectively, to simplify the structure. At this time, a valve or the like is positioned between each of the various pumps 412, 414, 424, 434 and 144 and one compressor 410, and various pumps 412, 414, 424 and 434 , 144) can be driven. However, the present invention is not limited thereto, and it is also possible that the pumps 412, 414, 424, 434, and 144 are driven by the different compressors 410 with a plurality of compressors 410. Various other variations are possible.

The compressor 410 may provide pressure using air pressure, hydraulic pressure, or the like. Various structures, methods, and the like known as the compressor 410 may be applied.

Basically, the control unit 500 basically controls or drives the pressure supply unit 400, the constant-volume mixing valve 140, and the like. That is, by controlling the shutoff or opening between the compressor 410 and the main pump 412, the bead puff 424, the cleanser pump 434 and the quantitative mixing pump 144, various pumps 412, 424, 434, 144 can be driven. Particularly, the control unit 500 can drive the constant volume mixing pump 144 when the operation of the constant volume mixing pump 144 is required, which will be described in more detail after the description of the constant volume mixing valve 140.

In addition, in the present embodiment, the control unit 500 receives various real-time information and the like to control the supply amount of the first subject 111a, the second subject 112a and the curing agent 114a, the amount of the coating composition 120a through the paint spraying unit 130, The injection speed, or the injection amount of the bead 210a, the injection time of the bead 210a through the bead injector 230, the injection speed, or the injection amount of the bead 210a.

Accordingly, the controller 500 can control the supply time, supply speed, supply amount, and the like of the first main body 111a, the second main body 112a, the hardening agent 114a, and the cleaning agent 310a.

Hereinafter, the quantitative mixing valve 140 will be described in detail with reference to FIG.

3 is a schematic view showing a part of the quantitative mixing valve 140, the cleanser storage part 310, and the paint spraying part 130 of the lane marking apparatus 10 shown in FIG.

In this embodiment, the metering mixing valve 140 may include a metering mixing pump 144 that applies a pressure to the paint mixing section 120 when necessary (e.g., a rest period). The quantity mixing valve 140 includes a first main path 141 having a first inlet 141a through which the first main body 111a is introduced and a first outlet 141b through which the first main body 111a is discharged, And a second main path 142 having a second inlet 142a into which the second subject 112a flows and a second outlet 142b through which the second subject 112a is discharged. At this time, the metering pump 144 may include a first pump portion 144a located in the first subject path 141 and a second pump portion 144b located in the second subject path 142. [

The first subject path 141 and the second subject path 142 may be fixed to the control block 146. [ Thus, the constant-volume mixing valve 140 can have a stable structure. The control block 146 may be provided with a path 143 through which the cleaning agent 310a flows. The path 143 through which the cleaning agent 310a flows may be connected to the first main path 141 and / or the second main path 142 by the cleaning agent 310a. The path 143 through which the cleaning agent 310a flows is formed to communicate with the first and second main paths 141 and 142 so that the first main path 141 and the second main path 142 are simultaneously connected to the first main path 141 and the second main path 142, (310a). Or a valve that controls or changes the path through which the cleaning agent 310a flows to the control block 420 or the path through which the cleaning agent 310a flows, 142 can be selectively cleaned. However, the present invention is not limited thereto, and it is also possible that the control block 146 is not provided.

The first subject 111a and the second subject 112a may flow through the first subject path 141 and the second subject path 142 during a period during which the coating composition 120a should be continuously sprayed, The first inlet 141a and the first outlet 141b and the second inlet 142a and the second outlet 142b are simultaneously opened. 3 (a), the constant-volume mixing pump 144 (particularly, the first and second pump portions 144a and 144b) is connected to the first inlet 141a and the first outlet 141b, And a first position (an upper position in the drawing) in which the second inlet 142a and the second outlet 142b are not blocked. Therefore, a certain amount of the first subject and the second subject are simultaneously introduced through the first inlet 141a and the second inlet 142a. Since the first and second motors 111a and 112a flow in a certain amount through the first inlet 141a and the second inlet 142a, the first and second motors 111a and 112a are mixed Can be constantly controlled. Therefore, the quality of the lane painted on the road can be kept excellent.

On the other hand, in the rest period in which the paint composition 120a is not sprayed from the paint sprayer 130 or the first subject 111a and the second subject 112a are not provided to the paint mixer 120, the quantitative mixing pump 144 moves to the second position (the lower position in the drawing) as in b). Then, the metering pump 144 (in particular, the first and second pump portions 144a and 144b) blocks the first inlet 141a and the second inlet 142a and opens the first outlet 141b and the second outlet 142a, Lt; RTI ID = 0.0 > 141b. &Lt; / RTI > The first subject 111a and the second subject 112a in the dosing mixing valve 140 (particularly the first subject path 141 and the second subject path 142) or the painting material mixing section 120 And pushes it toward the paint sprayer 130. Then, the first theme 111a and the second theme 112a can be blocked at the same time.

Also, the first motive 111a, the second motive 112a, the curing agent 114a, or the coating composition 120a located in the paint mixing unit 120 can be prevented from flowing backward in the opposite directions.

Unlike the present embodiment, in the absence of the metering valve 140, it is difficult to control mixing of the first and second subjects 111a and 112a in a fixed amount. The first main body 111a, the second main body 112a, the curing agent 114a or the coating composition 120a mixed with each other in the paint mixing part 120 are separated from the paint mixing part 120, And can move in a direction opposite to the yarn 130. Then, the hardening may occur before the paint mixing unit 120 or the paint mixing unit 120, thereby hindering the work to be performed at a later time. In particular, as in the present embodiment, curing can be performed in a short time when using the first subject 111a including the reactive methyl methacrylate (MMA) resin and the second subject 112a including the acrylic resin. Therefore, in the present embodiment, the effect of the constant-volume mixing valve 140 can be doubled.

As described above, the quantitative mixing valve 140 can be controlled by the control unit 500. That is, during the idle period, the control unit 500 drives the constant-volume mixing pump 144 to be positioned at the second position to provide the pressure toward the first outlet 141a and the second outlet 142a. During the operation period, the control unit 500 may cause the constant-volume mixing pump 144 to be positioned at the first position. At this time, the controller 500 controls the compressor 410 connected to the constant-volume mixing pump 144 to drive the constant-volume mixing valve 140.

The lane marking apparatus 10 described above can be installed in a vehicle and can perform lane marking. Such as the paint storage part 110, the bead storage part 210, the cleaning agent storage part 310, the pressure supply part 400, etc., can be installed on the vehicle. The paint sprayer 130 and the bead sprayer 230 are positioned on the lower side of the vehicle so that the bead sprayer 230 is positioned behind the paint sprayer 130 to the rear of the vehicle.

The lane painting method using the lane marking apparatus 10 according to the present embodiment is a method in which the first and second mottles 111a and 112a are supplied and mixed with the hardener 114a to form the paint composition 120a A working step for spraying the same, and a resting step for which no working step is performed. In the working step, the first and second motors 111a and 112a are simultaneously discharged and mixed in a quantitative manner. In the dormant phase, the first motive 11a and the second motive 112a are simultaneously discharged It is possible to prevent backflow.

More specifically, the work step is performed when the lane has to be painted. That is, the controller 500 drives the main pump 412 and the hardener pump 414 through the compressor 410 so that the first main body 111a, the second main body 112a, the curing agent 114a. The first main body 111a, the second main body 112a and the curing agent 114a are mixed and sprayed through the paint spraying part 130 in the paint mixing part 120. [ For example, the control unit 500 may control the paint sprayer 130 to spray the paint composition 120a at a desired spray speed, spray time, spray amount, or the like.
