The fixed block 124 supports a cradle 122 which is arranged long in the horizontal direction and the cradle 122 is provided with a pair of a first mounting portion 122a and a second mounting portion 122b.

A separate spray gun 89 may be provided for each of the plurality of first mounting portions 122a. In the case of applying lanes of various colors using the painting apparatus of the present embodiment, The first pump 10 and the second pump 30 are connected after the first tank 82 in which the paint is stored and the second tank 84 in which the white paint is stored in the second pump 30, It is possible to apply a lane of a plurality of colors to one road.

For example, when applying a white lane after applying a center line of yellow color to the center of the road, the first hydraulic valve 16e is opened and the second hydraulic valve 36e is closed to the first tank 82 After the yellow paint, the curing initiator and the set material to be stored are jetted by driving the first pump 10 to apply the center line of the yellow color, the first hydraulic valve 16e is closed and the second hydraulic valve 36e is opened The white paint, the curing initiator and the curing agent stored in the tank 2 84 can be sprayed by driving the second pump 30 to apply the white lane.

As described above, in the present embodiment, since only the first pump 10 or the second pump 30 can be driven individually by operating the first hydraulic valve 16e and the second hydraulic valve 36e, It is possible to perform various lane-painting operations.

Hereinafter, the operation of the lane marking apparatus for a liquid type paint according to an embodiment of the present invention will be described.

First, a first tank 82 in which a paint and a curing initiator are mixed and stored at 49: 1 is placed on the upper surface of the main body 92, the first supply pipe 14a is inserted into the first tank 82, The second tank 84 in which the paint and the curing agent are mixed and stored at a ratio of 49: 1 is placed on the upper surface of the main body 92 and the second supply pipe 34a is inserted into the second tank 84, The beads are injected into the hole 86 to complete the preparation of the painting operation.

Thereafter, the operator starts the engine 94f to drive the hydraulic motor 94a and the air motor 94g, and operates a plurality of knobs and buttons provided on the operating unit to select the type of lane to be painted, The lane end of the lane is selected.

When the first hydraulic valve 16e and the second hydraulic valve 36e are opened to supply the hydraulic pressure generated in the first chamber 94b, the first rod 12 of the first pump 10 is opened, The linear reciprocating motion to be projected and withdrawn from the part 12 proceeds and the paint and the curing initiator are sucked and discharged from the first tank 82 along the first supply pipe 14a to the first pump 10 and discharged from the second pump 30 The second rod 32 of the second pump 32 is projected and retracted from the second cylinder 32 so that the paint and the curing agent are supplied from the second tank 84 to the second pump 30 along the second supply pipe 34a, And is discharged.

The paint and the curing initiator and the curing agent supplied as described above are mixed in the mixing block 96 and discharged along the guide tube 91a. At this time, the first screw 91c and the second screw 91c, 2 mixed with the paint, the curing initiator and the curing agent alternately in the forward direction and the reverse direction by the two screws 91d, and is sprayed on the road through the spray gun 89 after being mixed while being stirred a number of times.

At this time, the paint, the curing initiator and the curing agent are stored in the distribution tank 112 and are supplied with a constant hydraulic pressure, and the same or similar hydraulic pressure is applied to the first pump 10 and the second pump 30 through the branch pipe 114 And they are mixed and supplied at a constant ratio.

At the beginning of the mixing injection of the paint and the curing initiator as described above, the operator confirms whether the supply amount of the curing initiator is increased to a set value while confirming the flow meter, and when the supply amount of the curing initiator is increased to the set value, The lane marking of the solid line or the dotted line is performed on the road while the vehicle is advanced or reversed.

When the lane painting operation is completed, the operator operates the first hydraulic valve 16e or the second hydraulic valve 36e to shut off the hydraulic pressure, stop the driving of the first pump 10 or the second pump 30 When the lever member 93 is opened with the first passage 97a and the second passage 98a opened by operating the first manual lever 97c and the second manual lever 98c, The cleaning fluid is supplied to allow the paint and the curing initiator remaining in the case 96a and the stirring portion 91 to be discharged to the outside through the spray gun 89. [

When the cleaning operation as described above is completed, the operator closes the lever member 93 to completely block the supply of the paint, the curing initiator, the curing agent, and the cleaning fluid.

Thus, a plurality of supply lines for supplying a coating material, a curing initiator, a hardener or a bead are provided, and the coating material, the curing initiator, the curing agent and the beads are supplied to the plurality of supply lines through all the supply lines or a part of the supply lines, It is possible to provide a lane-painting apparatus having an optional multi-feed line that can be mixed and injected.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. .

Further, although a lane-painting apparatus having an optional multi-supply line has been described as an example, it is merely an example, and a painting apparatus of the present invention can be used for products other than a lane-painting apparatus having an optional multi-supply line.
