Description

TECHNICAL FIELD [0001] The present invention relates to a coating method for coating a two-

More particularly, the present invention relates to a method of coating a paint for road surface marking of a liquid type, and more particularly, The present invention relates to a two-pack type coating composition for road surface marking which is capable of spraying a mixed solution of a coating material and a curing initiator and spraying a bead on the surface of a road surface using a paint device that provides hydraulic pressure and air pressure as power supplied from an engine .

In general, various buildings, ships, etc. perform painting work to obtain wall insulation or various exterior effects. Currently, the most commonly used method is airless spray method which applies pressure to paint and spray it. And can be divided into a single pump and a plural component pump depending on performance.

The one-component pump is a system in which the mixed paint is transferred to the piston motion by an air motor and atomized at the end of the spray gun. In this liquid type pump, the motive of the paint and the curing agent are separately transferred The mixture is mixed in the equipment at a desired mixing ratio, and the mixture is discharged by mixing the two components. When the components are mixed, the components are chemically reacted and cured, thereby transferring to a useful material.

In this conventional liquid type pump, the lower end of the main pump is axially coupled, an air motor is mounted on the upper part of the rod of the main pump, and an auxiliary pump having a lower end shaft- And the center of the operation is rotatably coupled to the support which is connected to the load of the auxiliary pump and is set up in the middle between the main pump and the auxiliary pump.

Accordingly, as the rod of the main pump reciprocates upward and downward due to the operation of the air motor, the rod of the auxiliary pump connected between the operations also reciprocates upward and downward, so that the paint of this liquid type is sprayed on the road to paint the lane.

BACKGROUND ART [0002] The background art of the present invention is disclosed in Korean Patent Registration No. 10-1176538 (published on Aug. 23, 2012, entitled " Two-component paint system ").

The lane-painting apparatus according to the prior art requires a compressor for driving the air motor because pneumatic pressure is used for supplying paint and curing agent. In order to provide the air pressure of about 150 Bar required for spraying paint, It is difficult to reduce the size and weight of the lane-painting apparatus because a large-sized compressor requiring space is installed.

In the lane marking apparatus according to the related art, it is difficult to reduce the number of parts of the paint apparatus because the drive unit for driving the vehicle, the drive unit for supplying the paint or hardening agent, and the drive unit for supplying the bead are separately provided There is a problem that the size and weight of the lane-painting apparatus can not be reduced.

In addition, since the pump for supplying paint and the pump for supplying the hardener have the same or similar capacity, the lane-painting apparatus according to the related art has a drawback that the mixing ratio of the paint and the hardener is maintained at about 1: 1 to 1: However, when the coating material and the curing initiator are mixed in a ratio of about 98: 2, the amount of supply between the coating material and the curing agent is remarkable and the precise mixing ratio is maintained, and the coating material and the curing agent can not be supplied.

Further, in the lane-painting apparatus according to the related art, since the rod of the pump for supplying the paint and the rod of the pump for supplying the hardening agent are alternately pressed, the paint and the hardening agent are alternately supplied. Therefore, The paint and the curing agent are not effectively mixed so that the lane is not partially cured after the completion of the lane painting operation.

Therefore, there is a need for improvement.

The present invention relates to a paint coating method and a paint coating method that use a paint apparatus that mixes and injects a paint and a curing initiator at a predetermined ratio by a paint apparatus that simultaneously supplies paint and an initiator by engine operation, It is an object of the present invention to provide a method of coating a coating solution for road surface marking which is capable of spraying a mixed solution of a coating material and a curing initiator and spraying beads to construct a road surface mark.

The above lane painting method is performed by a lane marking apparatus for realizing the present embodiment, and the lane marking apparatus for implementing the present embodiment is provided with a first tank 82 in which a paint is stored, A main body 92 having a second tank 84 in which a curing initiator that induces the curing initiator to be stored and a wheel 92a for movement; An engine 94f installed in the main body 92 and an engine 94f for converting the power provided from the engine 94f into hydraulic pressure so that the power of the wheel 92a or the power of the wheel 92a And a mixing block 96 for mixing and supplying a coating material and a curing initiator provided by the pumping part 100. The mixing block 96 is provided with a hydraulic motor 94a for providing a driving force.

The main body 92 of this embodiment is provided with a plurality of wheels 92a and the wheels 92a are rotated forward or backward by the power of the hydraulic motor 94a to advance or retract the main body 92.

A support plate 76a is provided at the rear end of the main body 92 so as to allow an operator to ride on the support body 76. An operator and a handle capable of operating the main body 92 in a state in which the operator is on the front of the support plate 76a Respectively.

An engine 94f is provided in the front portion of the main body 92 and a hydraulic motor 94a is connected to the output shaft of the engine 94f so that the power of the engine 94f is transmitted to form a hydraulic pressure.

A clutch 94e is provided between the engine 94f and the hydraulic motor 94a to determine whether or not to transmit power by attaching and detaching the disk. An air motor 94g is connected to the drive shaft of the hydraulic motor 94a, So that the hydraulic pressure and the pneumatic pressure can be formed.

A distribution valve 94d is provided at one side of the clutch 94e to distribute the hydraulic pressure supplied from the hydraulic motor 94a to the wheel 92a or to the side of the pump 100, Thereby forming the driving unit 94.

Accordingly, in this embodiment, since the driving of the main body 92, the driving of the pumping part 100 and the injection of the beads can be performed simultaneously by one engine 94f, the driving part 94, And the size of the driving unit 94 is remarkably reduced.

As described above, since the number of the driving units 94 is reduced, the size and weight of the coloring device can be reduced, and the number of parts required for manufacturing the coloring device can be reduced, thereby reducing the time and cost required for manufacturing the coloring device And the space required for the painting operation is reduced.

The display unit for displaying the driving state of the main body 92 or the pumping unit 100 is mounted on the main body 92 so as to face the support plate 76a and the support unit 76 extending upward from the main body 92, And a pumping unit 100 is installed on one side of the support table 76.

An operation handle capable of manipulating the forward or backward movement of the main body 92 is provided at the upper end of the support table 76 so that the operator can ride the support plate 76a to move the main body 92 forward or backward .

Since the pumping part 100 is provided on one side of the support 76, when the driving part 94 is operated, the hydraulic pressure supplied from the driving part 94 is supplied to the pumping part 100 to drive the pumping part 100 .

The step S20 of mixing and spraying the coating material of the present embodiment with the curing initiator includes a first pump 10 installed in the main body 92 for supplying paint and a second pump 10 provided in a smaller capacity than the first pump 10 By operating the second pump 30 interlocked with the first pump 10 by the power transmission portions 50 and 70 so as to supply the bake hardening initiator.

The pumping unit 100 of this embodiment is configured to perform the step S20 of mixing and spraying the paint and the curing initiator. The pumping unit 100 includes a first load A second pump 30 having a first rod 10 having a first rod 12 and a second rod 32 capable of moving up and down to supply a hardening initiator; And a power transmitting portion (50, 70) for transmitting the power to the rod (32).

The pumping unit 100 of the present embodiment supplies the coating material and the curing initiator separately, and the curing initiator is mixed with the coating material immediately before the coating material is sprayed, so that the curing action of the coating material is started. do.

Accordingly, when the paint supplied by the first pump 10 and the curing initiator supplied by the second pump 30 are mixed and sprayed on the road, the paint is cured within a short time and forms a lane.

The first pump 10 is driven by the hydraulic pressure supplied from the driving unit 94 and sucks and discharges the paint from the first tank 82 in which the paint is stored and the second pump 30 discharges the paint from the second tank 84 ), And the paint and the curing initiator are mixed with each other while passing through the mixing block 96, and then sprayed on the road.

The present embodiment is provided with the power transmitting portions 50 and 70 for transmitting the linear motion of the first rod 12 projected from the first pump 10 to the second rod 32 of the second pump 30 A separate drive device for providing an external force to the second rod 32 is not required in addition to the drive portion 94 for supplying the hydraulic pressure to the first rod 12, thereby reducing the number of pieces of the lane paint system, Can be reduced.

Since the mixing ratio of the coating material to the curing initiator is about 98: 2 in the two-liquid coating material used for the lane-painting, the supply amount of the coating material supplied by the driving of the first pump 10 and the supply amount of the coating material The difference in the supply amount of the curing initiator supplied by the driving of the substrate is remarkable.

The conventional lane painting apparatus has a problem in that it is not easy to supply while maintaining the mixing ratio of the coating material and the curing initiator having a remarkable difference in the amount of supply while simultaneously driving the two pumps by one driving unit 94. [

On the other hand, since the first rod 12 and the second rod 32 are connected by the power transmission portions 50 and 70, the linear reciprocating motion of the first rod 12 is transmitted to the second rod 32, The momentum of the first rod 12 is reduced by the action of the power transmitting portions 50 and 70 and transmitted to the second rod 32. [

Since the first pump 10 of this embodiment has a larger capacity than the second pump 30, when the linear motion of the first rod 12 is transferred to the linear motion of the second rod 32, There is no need for a separate reduction device or change device for reducing the momentum of the rod 12 and transmitting it to the second rod 32.

As described above, in this embodiment, the first pump 10 has a larger capacity than the second pump 30 in order to maintain the supply amount by the first pump 10 and the supply amount difference by the second pump 30 Even if the momentum of the first rod 12 is transmitted to the second rod 32 without passing through a separate speed reducing device or a power conversion device, the supply amount of the hardening initiator provided by the second pump 30 is smaller than the supply amount of the paint Which is a significantly smaller state than that of the first embodiment.

As described above, since the first pump 10 having a relatively large capacity and the second pump 30 having a small capacity are connected to be linked by the power transmitting portion, the curing initiator Can be supplied together with the paint while maintaining an accurate blending ratio.

The first pump 10 includes a first cylinder portion 14a to which a first supply pipe 14a to which paint is supplied and a first discharge pipe 14b to discharge paint are connected and a first rod 12 A first hydraulic pressure supply pipe 16b connected to the first cylinder portion 14 and having a connection hole portion 16a through which the first rod 12 is exposed and to which a working fluid delivered from the driving portion 94 is supplied, And an operating portion 16 to which the first hydraulic-pressure discharge pipe 16c is connected.

The first pump 10 is installed on a support base 76 provided in a vertical direction to a main body 92 constituting a lane painting apparatus and is provided with a first hydraulic pressure supply pipe 16b and a first hydraulic pressure supply pipe 16b on the first cylinder portion 14, The first cylinder 82 is connected to the first cylinder 82. The first cylinder 82 is connected to the first cylinder 82. The first cylinder 82 is connected to the first cylinder 82, And a first discharge pipe 14b is provided on a side surface of the first cylinder portion.

When the first pump 10 is driven by the hydraulic pressure supplied from the driving unit 94, the paint stored in the first tank 82 is supplied to the first cylinder unit 14 along the first supply pipe 14a, The paint discharged by the linear reciprocating motion of the first rod 12 is discharged toward the mixing block 96 along the first discharge pipe 14b.

Since the second pump 30 includes the second cylinder portion 34 to which the second supply pipe 34a to which the curing initiator is supplied and the second discharge pipe 34b to which the curing initiator is discharged, Is transmitted to the second rod 32, the curing initiator stored in the second tank 84 is sucked and supplied to the mixing block 96 along the second discharge pipe 34b.

At this time, in this embodiment, the first rod 12 and the second rod 32 are simultaneously inserted into the first cylinder portion 14 and the second cylinder portion 34 by the transmitting member 50, 1 cylinder portion 14 and the second cylinder portion 34, the supply of the paint and the supply of the curing initiator are simultaneously performed on the mixing block 96 side.

As described above, in the present embodiment, since the paint and the curing initiator are simultaneously supplied at a constant mixing ratio while the first rod 12 and the second rod 32 are simultaneously lowered or raised, the paint and the curing initiator are evenly mixed It is possible to perform a lane-painting operation in which the problem that the lane is not partially hardened does not occur and the entire lane is hardened evenly within a short time.

A circulation pipe 34c for circulating a curing initiator through the second tank 84 is connected to the second cylinder 34 and a curing initiator which overflows due to the operation of the second rod 32 The overflow pipe 34d is connected to the second tank 84 so that the overflow pipe 34d can be recovered.

In this embodiment, a first chamber 94b in which air pressure is stored between the air motor 94g and the third tank 86 is provided, and between the first pump 10 and the mixing block 96, Two chambers 94c are installed.

The paint discharged from the first pump 10 is filled in the second chamber 94c and then supplied to the mixing block 96. The second chamber 94c is provided with a filter capable of removing foreign substances contained in the paint do.

The second chamber 94c is provided with a lever for switching the supply direction of the paint and a recovery pipe 94d for circulating the paint from the second chamber 94c to the first tank 82 is provided.

Therefore, when the first pump 10 is driven after the first supply pipe 14a is disconnected from the first tank 82 and the lever provided on the recovery pipe 94d is operated after the completion of the second coloring operation, The paint remaining in the first tank 14a and the first pump 10 can be recovered to the first tank 82 through the recovery pipe 94d.

As described above, when the first pump 10 is driven by the hydraulic pressure supplied from the hydraulic motor 94a, the first rod 12, which forms the first pump 10, The linear reciprocating motion of the first rod 12 is transmitted to the second rod 32 of the second pump 30 by the operation of the power transmitting portions 50 and 70. [

Therefore, in this embodiment, since the first pump 10 and the second pump 30 can be simultaneously driven by one driving unit 94 without a separate driving unit, And the curing initiator can be supplied at the same time.

The power transmitting portions 50 and 70 include a transmitting member 50 for connecting the first rod 12 and the second rod 32 to each other and a transmitting member 50 for supporting the second pump 30, (Not shown).

The fixing member 70 includes a horizontal portion 72 rotatably connected to the first pump 10 and rotatably supported by the second pump 30, And a bending portion 74 to which the bushing 50 is rotatably connected.

The lower end of the third cylinder part 36 is rotatably mounted on the horizontal part 72 and the transmitting member 50 is rotatably mounted on the upper end of the bent part 74 bent upward from the horizontal part 72 and extending upward. A hinge portion 54 is provided.

A gap is formed between the horizontal part 72 and the transmitting member 50 so that the second pump 30 is installed and one end of the transmitting member 50 connected to the first rod 12 is reciprocated linearly The transmitting member 50 is rotated about the hinge portion 54 to reciprocate the second rod 32 in the vertical direction.

A first connecting portion 52 is rotatably connected to the first rod 12 at one end of the transmitting member 50 and is rotatably connected to the other end of the transmitting member 50 And a second connection portion 56 is provided between the first connection portion 52 and the hinge portion 54 to which the second rod 32 is connected.

The moving distance of the central portion of the transmitting member 50 to which the second rod 32 is connected is shorter than the moving distance of the one end of the transmitting member 50 to which the first rod 12 is connected, Is transmitted to the second rod 32 while the momentum of the second rod 32 is reduced.

The difference between the momentum of the first rod 12 and the momentum of the second rod 32 depends on the connection structure of the transmitting member 50 and the fixing member 70 and the mounting position of the second pump 30, .

The first connecting portion 52 includes a connecting piece 52a rotatably connected to the transmitting member 50 and a fixing pin 52b coupled to the connecting piece 52a and inserted into the first rod 12. [

Since the connecting piece 52a is rotatably installed at one end of the transmitting member 50 and the fixing pin 52b press-fitted into the connecting piece 52a is inserted and connected to the circumferential surface of the first rod 12, The connecting piece 52a linearly reciprocates in the vertical direction and one end of the transmitting member 50 rotatably connected to the connecting piece 52a is moved in the vertical direction and the connecting piece 52a And the transmitting member 50 are varied according to the position of the first rod 12. [

The position of the second connection portion 56 can be moved along the transmission member 50 because the transmission member 50 is provided with the angle adjusting portion 58 to which the second connection portion 56 is movably connected. The angle formed between the second pump 30 and the horizontal portion 72 is changed when the upper end position of the second rod 32 connected to the transmitting member 50 is changed by the second connecting portion 56. [

When the angle of the second pump 30 is changed by varying the position of the second connection portion 56 as described above, the momentum at which the second rod 32 is lowered or raised when the transmission member 50 is driven is varied The supply amount of the curing initiator supplied by the driving of the second pump 30 can be adjusted.

The angle adjusting portion 58 includes a sliding hole portion 58a formed in the transmitting member 50 and a scale portion 58b formed to face the sliding hole portion 58a.

Accordingly, the operator can adjust the supply amount of the curing initiator while moving the second connection portion 56 along the sliding hole portion 58a and adjust the position of the second connection portion 56 along the sliding hole portion 58a to the transmitting member 50, The movement amount of the second rod 32 is increased to increase the supply amount of the curing initiator and the position of the second connection portion 56 is moved to the other side of the transmission member 50 along the sliding hole portion 58a, The amount of movement of the two rods 32 is reduced, and the supply amount of the curing initiator is reduced.

The second connecting portion 56 includes a moving shaft which is movably inserted into the sliding hole portion 58a and a connecting member 56b which is engaged with the moving shaft and a connecting member 56b which is protruded from the connecting member 56b, And a lever 56c member for fixing the movement shaft.

When the operator holds the lever 56c and rotates the engaging member 56b in the forward direction, the moving shaft is inserted into the engaging member 56b, so that the engaging member 56b is brought into close contact with the outer wall of the transmitting member 50, So that the second rod 32 connected to the shaft is not moved.

Conversely, when the operator holds the lever 56c and rotates the engaging member 56b in the opposite direction, the moving shaft protrudes from the engaging member 56b, and a gap is formed between the engaging member 56b and the transmitting member 50, The connected second rod 32 is shifted to be movable along the sliding hole portion 58a.

Accordingly, the operator can vary the supply amount of the hardening initiator by adjusting the angle of the second pump 30 while moving the second rod 32 along the sliding hole portion 58a.

At this time, the operator can precisely adjust the supply amount of the curing initiator while checking the graduation portion 58b formed opposite to the sliding hole portion 58a. On one side of the engagement member 56b, the projecting portion 58b opposed to the graduation portion 58b So that the protruding portion indicates the scale portion 58b.

The mixing block 96 includes a first flow path 97a extending from the pump and connected to a first discharge pipe 14b for supplying paint and a second flow path 98a connected to a second discharge pipe for supplying a hardening initiator, An agitating portion 91 provided in a discharge hole portion 91e where the first flow path 97a and the second flow path 98a are joined and discharging the paint with the curing initiator while stirring, And a lever member 93 for opening and closing the first flow path 97a and the second flow path 98a.

A first tank 82, a second tank 84 and a third tank 86 are provided on the protruding portion of the main body 92, and the first tank 82, the second tank 84, A case 96a is provided at one side of the protrusion.

A first supply hole portion 97 and a second supply hole portion 98 are formed on the upper surface of the case 96a and a first flow path 97a connected to the first supply hole portion 97 is formed in the case 96a. The first flow path 97a and the second flow path 98a are joined at the lower portion of the case 96a and connected to the case 96a And the discharge hole 91e formed at the lower end of the discharge hole 91e.

The paint supplied to the inside of the case 96a through the first supply hole 97 and the curing initiator flowing into the case 96a through the second supply hole 98 are discharged through the first flow path 97a and the second Passes through the flow passage 98a and is discharged through the discharge hole 91e and mixed.

The paint and the curing initiator, which are discharged through the discharge hole 91e, are agitated while alternating between normal rotation and reverse rotation by the agitating part 91, so that the paint and the curing initiator are effectively mixed.
