The present invention relates to a lane painting apparatus and a lane painting method using the same. More particularly, the present invention relates to a vehicle lane painting apparatus and a lane painting method using the same, which are installed in a vehicle and automatically paint the lane while the vehicle moves.

Lane coating is performed by combining three elements, one or two lines, yellow or white, solid line or dashed line, and two kinds of paint are used with paint and mixed with powder of stone and resin. There is.

The prior art uses different lane painting methods depending on the type of paint. In the case of using paint, it is common to put all equipment necessary for lane painting in a loading box of a vehicle and spray the paint through a nozzle while the vehicle is traveling. to be. This is because there is no problem in lane painting by spraying paint even when the vehicle is traveling at a speed of about 10-30 km / h. Therefore, it is the maximum advantage that can be a quick operation, the paint has a disadvantage in that its durability is poor and easy to discolor compared to the fusion-based paint to be described later.

In the case of fusion-based paints using stone powder (CaCO ₃ ) and resins, paints mixed with both materials and other additives in a proportion are put in a melting tank mounted in a vehicle loading box and heated to make a molten state. It is transferred to a lane marker of a type (aka fusion rod marking machine), and the worker paints the lane while pushing the rod marker.

In spite of the excellent durability of the lane itself and the color of mixed paint, it is suitable for lane painting, even when the vehicle runs at the lowest speed (about 10 ~ 15km) that ordinary vehicles can achieve at idle. This is because there is a problem such as being broken in the process of being placed on, or the surface of the paint is partially cured, causing the lane to come up after construction.

The lane-painting vehicle which solved such a problem is disclosed by Unexamined-Japanese-Patent No. 2002-13460.

However, since the lane formed by the conventional method of painting using the lane paint apparatus is painted on the road to have a constant thickness, lane identification is poor when driving at night or when the road surface is wet or rained. Therefore, to increase lane identification, lane identification devices had to be installed on the road separately from lanes.

Accordingly, it is an object of the present invention to ensure sufficient lane identification even with painted lanes.

In order to achieve the above object, the present invention provides a lane paint apparatus installed in a vehicle, comprising: a paint supply unit for supplying a paint having a predetermined temperature including glass grains; A lane paint portion which receives the paint from the paint supply part and applies the paint to paint a base lane of a predetermined width on a roadway; And a protrusion forming unit installed at the rear of the lane coating unit and discharging the paint supplied from the paint supply unit at predetermined time intervals to form protrusions at predetermined intervals in the base lane.

In the present invention, the heat insulating part may further include a heat medium circulation path formed to pass between the ejectors.

The present invention also provides a lane painting method using the above-described vehicle lane painting apparatus. That is, (a) forming a base lane by applying the paint of a predetermined temperature including the glass grains on the roadway painted portion; (b) the projection forming unit discharging the paint to the base lane at predetermined time intervals in a predetermined form to form the projections at predetermined intervals in the base lane; It provides a lane painting method used.

In the lane coating method according to the present invention, after the step (b) further comprises the step of (c) spraying the paint on the base lane formed with the projection to form a coating layer.

In the lane painting method according to the present invention, steps (a) to (c) are continuously performed.

In the lane painting method according to the present invention, the protrusions are formed in step (b) by matching the rows in a direction perpendicular to the direction in which the base lane is painted.

Hereinafter, with reference to the accompanying drawings will be described in detail an embodiment of the present invention.

1 is a block diagram illustrating a vehicle lane painting apparatus 100 according to an embodiment of the present invention. FIG. 2 is a schematic diagram illustrating a vehicle 1 in which the lane paint apparatus 100 of FIG. 1 is installed. 3 is an enlarged view of portion “A” of FIG. 2 and is an enlarged view of a lane 94 painted on a road 90. 4 is a perspective view illustrating the lane paint apparatus 100 of FIG. 1.

And a projection forming portion 30 to form projections 92 at predetermined intervals on the painted base lane 91 by discharging the paint supplied from the substrate at predetermined time intervals. It is installed at the back and sprays the paint supplied from the paint supply unit 10 to the base lane 91 formed with the projection 92 It comprises a bead gun (70) to form a coating film (93). At this time, the base lane 91, the projection 92 and the coating film 93 constitutes a lane 94, the lane coating so that the base lane 91, the projection 92 and the coating film 93 can be formed in sequence It is preferable that the part 20, the protrusion forming part 30, and the bead gun 70 be provided on substantially the same line.

Then, the heat medium oil is provided and circulated to the lane paint part 20 and the protrusion forming part 30 to adjust the temperature of the melted paint provided from the paint supply part 10 to the lane paint part 20 and the protrusion forming part 30. It further includes a heat medium supply unit 80 to maintain the temperature. The heat medium supply unit 80 forces the heat medium oil to circulate the heat medium oil between the heat medium tank 81 in which the heat medium oil is stored, and between the heat medium tank 81, the lane paint part 20, and the protrusion forming part 30. It includes a circulation pump 82 for circulating to.

Therefore, the lane paint apparatus 100 according to the embodiment of the present invention may improve lane identification at night or in rain by forming the lane 94 having the protrusion 92 formed thereon. That is, since the light emitted from the vehicle's illuminator is reflected by the projection 92 protruding from the lane 94 when the vehicle is driving at night, the driver can easily identify the lane 94.

Referring to the lane paint apparatus 100 according to the embodiment of the present invention in detail, the paint supply unit 10, as shown in Figs. 1 and 5, by making the paint in a molten state lane coating unit 20 And a means for providing to the protrusion forming portion 30 and the bead gun 70, a melting tank 11, a heating burner 12, a stirring motor 13, and a discharge valve 14. The temperature of the paint in the melting tank 11 is heated by the heating burner 12 so as to maintain 190 to 210 degrees. Although not shown, in the melting tank 11, a stirring blade for stirring the paint is connected to the shaft of the stirring motor 13. In this case, it is preferable to use a paint including a glass egg, a resin, a stone (CaCO 3), a pigment, and the like mixed in a predetermined ratio.

The lane paint part 20 receives the paint in the molten state from the discharge valve 14 of the paint supply part 10 and paints the lane in a fusion manner, as shown in FIGS. 1, 4, and 6. And a storage tank 21 for temporarily storing the paint, a paint discharge port 22 formed at the bottom of the bottom surface of the storage tank 21, an air cylinder 23 for opening and closing the paint discharge port 22, and In order to form a jaw on the upper surface, a flat gate 24 lifted by an air cylinder 27 to be described later, a fixed gate 26 in contact with the flat gate 24 and an open groove 25 formed at the bottom thereof, It includes an air cylinder 27 for lifting the flat gate 24 at each distance.

In this case, when painting a normal base lane, the bottom of the flat gate 24 and the bottom of the fixed gate 26 coincide with each other. In the case where a jaw is to be formed on the upper surface, a stroke corresponding to the height of the jaw to be formed is reciprocated. The flat plate 24 is set so that the flat plate 24 is moved up and down for a predetermined time by the air cylinder 27 at a predetermined distance.

And the storage tank 21 maintains the temperature of the paint stored in the storage tank 21 by the heat insulating jacket 28 surrounding the outer surface of the storage tank 21 constant. At this time, the heat medium oil supplied from the heat medium supply part (80 of FIG. 1) circulates in the storage tank 21 and the heat insulating jacket 28 to maintain a constant temperature of the paint in the storage tank 21. Here, reference numeral 83 in FIG. 4 denotes an input pipe into which the heat medium oil is input, and reference numeral 84 denotes a discharge pipe through which the heat medium oil is discharged. The temperature of the paint stored in the reservoir 21 can be confirmed through the temperature gauge 29.

It is preferable to keep the temperature of the paint in the storage tank 21 to 150-180 degree here. The reason is that when the temperature of the paint in the reservoir 21 is 150 degrees or less, the viscosity of the paint applied through the paint outlet 22 increases, so that the paint is boiled in the process of being applied to the road surface, or the surface of the paint The phenomenon of hardening to a portion may occur and a problem such as lifting of a lane after construction may occur. On the contrary, when the temperature of the paint is 180 degrees or more, since the viscosity of the paint applied through the paint outlet 22 is lowered, the paint may not be maintained in a constant shape in the process of being applied to the road surface.

The protrusion forming unit 30 is a portion for forming a plurality of protrusions in the base lane at predetermined intervals by discharging a predetermined amount of paint on the lane painted by the lane coating unit 20. As illustrated in FIGS. 7 to 9, a hopper 40 for storing the paint supplied from the paint supply unit 20 and a lower end of the hopper 40 are disposed to discharge the paint in the hopper 40. The ejector 50 and the heat retention part 60 which heats around the hopper 40 and the ejector 50, and maintains the temperature of the paint discharged to the ejector 50 uniformly. At this time, the hopper 40 is supported by the support 31 which is connected to the rear of the lane paint portion 20.

The hopper 40 is provided with a storage space 45 for storing the paint, and is provided with an agitator 41 for stirring the paint stored inside. The stirrer 41 includes a stirring motor 42 having a rotating shaft 43 and a stirring blade 44 coupled to the rotating shaft 43.                     

Here, the stirring motor 42 is installed outside the hopper 40, and the rotating shaft 43 of the stirring motor extends into the storage space 45 of the hopper. Stir blade 44 has a structure coupled to the rotating shaft 43 located in the storage space 45 of the hopper. Therefore, the stirring blade 44 coupled to the rotary shaft 43 rotates as the stirring motor 42 is driven to agitate the paint stored in the storage space 45 of the hopper.

The ejectors 50 are arranged in rows at the lower end of the hopper 40 and include a plurality of nozzles 51 arranged in a line at a predetermined interval in a direction perpendicular to the direction in which the base lanes are painted. That is, the ejector 50 includes a plurality of nozzles 51 for discharging a predetermined form of the paint stored in the hopper 40, and a switch 52 installed at an end of the nozzle 51 close to the ground to open and close the nozzle 51. It includes. The switch 52 includes an opening and closing plate 54 having a hole 55 corresponding to the nozzle 51, and an air cylinder 53 for opening and closing the nozzle 51 by horizontally moving the opening and closing plate 54 side to side. do. At this time, the cylinder rod 53a of the air cylinder 53 is installed in parallel to the opening and closing plate 54, the opening and closing plate 54 and the cylinder rod 53a is connected by a bracket 56 of the letter "L" shape According to the operation of the air cylinder 53, the opening and closing plate 54 is horizontally moved to the left and right to open and close the nozzle 51. And the guide plate 57 for guiding the horizontal movement of the opening and closing plate 54 to the left and right is installed below the opening and closing plate 54, the slot 58 is formed so that all the holes 55 of the opening and closing plate is exposed. .

Therefore, when the opening 55 of the opening and closing plate coincides with the nozzle 51, the paint is discharged through the nozzle 51, and when the opening and closing plate 54 blocks the nozzle 51, the discharge of the coating is stopped.

The heat insulating part 60 maintains a constant temperature of the paint stored in the hopper 40 and the ejector 50 by the heat insulating jacket 61 surrounding the hopper 40 and the ejector 50. At this time, inside the heat insulating jacket 61 surrounding the hopper 40 and the ejector 50, the heat medium oil supplied through the inlet pipe 85 from the heat medium supply unit (80 of FIG. 1) circulates while the hopper 40 and The temperature of the paint in the ejector 50 is kept constant. For example, the temperature of the paint is preferably maintained at 140 to 145 degrees.

In particular, the heat insulating part 60 includes a burner 62 for heating the heat medium oil in the heat insulating jacket 61, a heat pipe 63 provided in close proximity to the lower end of the nozzle 51 of the ejector 50, The heating medium circulation path 64 is provided so that the nozzle 51 may pass zigzag between the lower ends. Of course, in the heat medium circulation path 64, the heat medium oil supplied from the heat medium supply part (80 of FIG. 1) circulates to heat the paint in the nozzle 51 before being discharged from the nozzle 51 to maintain the temperature of the paint.

The reason why the temperature of the paint in the protruding portion 30 is maintained by further reinforcing the heat insulating portion 60 as compared with the lane painted portion 20 is that the protruding portion 30 is lower than the lane painted portion 20. The projections must be formed by discharging a relatively small amount of paint to the lanes, because the amount of the discharged paints is small and the paints cool down relatively quickly, so that the temperature of the discharged paints is maintained at a temperature necessary for base lane fusion.

The bead gun 70 is a device for injecting paint into the base lane in which the protrusion is formed to stably fix the protrusion formed in the base lane, and is installed at the rear of the protrusion forming unit 30. At this time, the bead gun 70 is supported by the bead gun support 71 which connects with the outer surface of the hopper 40. It is preferable that the bead gun 70 is slightly inclined toward the nozzle 51 of the protrusion forming portion so as to form a coating layer by spraying paint on the protrusion formed by the protrusion forming portion 30.

A method of painting a lane with the lane painting apparatus 100 according to the embodiment of the present invention will be described.

First, as shown in FIGS. 1 and 6, the lane painter 20 applies the paint to the road 90 to form the base lane 91. That is, the base lane 91 is formed by applying the paint of the storage tank 21 storing the paint supplied from the paint supply unit 10 to the road through the paint discharge port 22.

Next, as shown in FIGS. 3 and 7, the process of forming the protrusions 92 at predetermined intervals on the painted base lane 91 is performed. That is, the ejector 50 of the protrusion forming portion discharges the paint in the hopper 40 onto the base lane 91 at predetermined time intervals, thereby allowing the protrusions 92 to be spaced at the base lane 91 at a predetermined interval. Can be formed. At this time, since the nozzles 51 of the ejector are provided in a direction perpendicular to the direction in which the base lane 91 is painted, the protrusions 92 are formed substantially in a line.

Finally, the process of forming the coating layer 93 by coating the base lane 91 on which the protrusions 92 are formed is performed. That is, the bead gun 70 installed behind the protrusion forming unit 30 forms a coating film 93 for spraying paint to coat the base lane 91 on which the protrusion 92 is formed, thereby forming a lane having the protrusion 92 ( 94) is completed.

At this time, the lane paint apparatus 100 according to the present invention moves the vehicle at a predetermined speed, painting the base lane 91, forming the protrusions 92 and forming the coating film 93. Proceed with the steps sequentially.

On the other hand, the embodiments of the present invention disclosed in the specification and drawings are merely presented specific examples to aid understanding, and are not intended to limit the scope of the present invention. In addition to the embodiments disclosed herein, it is apparent to those skilled in the art that other modifications based on the technical idea of the present invention may be implemented.

Therefore, according to the structure of the present invention, the lane paint portion, the protrusion forming portion and the bead gun are sequentially installed in the traveling direction of the vehicle, thereby forming a lane having protrusions at predetermined intervals in a direction perpendicular to the painted base lane. As a result, lanes are clearly visible at night or during wet or rainy roads. That is, by forming a plurality of protrusions at predetermined intervals in the longitudinal direction of the lane so as to protrude from the plane of the lane, the driver can easily identify the lane because the light irradiated from the illuminator of the vehicle is reflected on the protrusion formed on the lane of the lane. You can do it.
