Description

Description: TECHNICAL FIELD The present invention relates to a method and an apparatus for constructing a road marking line such as a road marking line.

(Prior Art) Conventionally, if the road marking line has a smooth upper surface, it is dangerous for a car to slip easily on the line, and it is flooded in the rain at night, and the visual recognition effect is significantly impaired. Line is required, for example Japanese Patent Publication Sho 55
-27922 discloses a method of constructing the above-mentioned improved line. The construction method of this line is that the molten paint on the road surface flows out from the slit part of the tank and is applied in a line shape with an appropriate thickness and width, and the hardened or semi-cured paint, etc. on the upper surface of the paint applied on the road surface. The protrusion forming paint is made to flow out and fall from the tank, and the protrusion forming paint is welded and fixed onto the line-shaped paint on the road surface.

(Problems to be Solved by the Invention) However, in such a conventional line construction method, since the projection-forming coating material flows out and drops onto the upper surface of the line-shaped coating material applied to the road surface, it is necessary to use the two coating materials for the line and the projection. There is a problem in that workability is poor because different types of paints must be prepared separately and outflow coating of these paints is performed separately. Further, unless the coating material for forming the protrusions is dropped and then heated by a gas burner, the coating materials cannot be sufficiently welded to each other, and there is a problem that the construction is troublesome.

It is an object of the present invention to provide a road marking line construction method and a device therefor, which solves the conventional problems and has good workability.

(Means for Solving the Problems) In order to solve the above problems, a method of constructing a road marking line of the present invention is to move a dolly, and melt the paint melted from a slit portion of a paint tank on the dolly on a road surface with a predetermined width. To form a belt-like material, and periodically through the actuating portion consisting of a cam and a lever device that interlocks with the rotation of the wheels of the carriage, a coating film thickness adjusting member provided on the rear surface of the slit portion so as to be vertically movable. Lift it to widen the paint outlet, increase the amount of paint flowing out from the slit part and form protrusions on the strip at a predetermined interval, interlocking with the rotation of the wheel of the trolley via the rotation transmission mechanism. The bead-dispersing roll behind the slit portion is rotated to disperse and adhere the glass beads on the strip. or,
A small bead sprinkling roll that sprinkles small-diameter glass beads is rotated at all times or when the upper surface of the strip below the roll is smooth, and a large-bead sprinkling roll that sprinkles large-diameter glass beads is projected onto the upper surface of the strip below the roll. The glass beads are sprinkled by being rotated when the part is formed.

The road marking line construction device of the present invention allows molten paint to flow out from a slit portion of a paint tank on a trolley to a road surface with a predetermined width, and spreads and adheres glass beads to the upper surface of the paint applied to the road surface by a bead spreader. In such a road marking line construction device, a cam that interlocks with the rotation of the wheels of the carriage and a lever device that operates by the cam are provided, and a coating film thickness adjusting member that is vertically movable on the rear surface of the slit portion is connected to the lever device. By rotating the cam, the adjusting member is periodically lifted via the lever device to widen the paint outlet and increase the amount of paint flowing out from the slit portion. The machine is equipped with a bead spraying roll, and the rotation of the bead spraying roll is interlocked with the rotation of the wheels of the trolley via a rotation transmission mechanism. Further, the bead sprinkling machine is provided with a small bead sprinkling roll that scatters small-diameter glass beads and a large bead sprinkling roll that scatters large-diameter glass beads, and the rotation transmission mechanism is interlocked with the cam shaft, and the rotation transmission mechanism is An intermittent transmission mechanism is incorporated so that the rotation cycle of the large bead spraying roll and the stop cycle of the small bead spraying roll correspond to the operating cycle of the lever device by the cam, respectively, so that both rolls intermittently stop rotating. , When the lever device in which the amount of paint flowing out from the slit portion is increased is actuated, the large bead spraying roll that is stopped is rotated via the intermittent transmission mechanism, and the small bead spraying roll that is rotating is stopped. It is a thing.

In the embodiment described above, the glass beads (51) with a small diameter and the glass beads with a large diameter, respectively (52), are to be sprayed to a specific location, but the small beads spraying roll (33) is constantly rotated to form a strip ( Scatter small glass beads (51) on the entire upper surface of (S),
Large diameter glass beads (52) may be sprinkled on the protrusions (50).
Further, high-intensity glass beads may be dispersed instead of the large-diameter glass beads (52). Further, glass beads of appropriate diameter and brightness may be sprayed regardless of the smoothness of the upper surface of the belt-like material (S) or the projection (50). In this case, the dispersion of the glass beads is moved by the rotation of the wheel (2), but the bead dispersion roll may be directly connected to the rotation transmission mechanism (14) without the intermittent transmission mechanism (34).

Further, the width of the coating film thickness adjusting member (16) may be determined according to the width of the protrusion (50) formed on the strip (S), and the width of the strip (S) is appropriately smaller than that. I have to

(Effects of the Invention) As described in detail above, according to the present invention, the coating film thickness adjusting member on the rear surface of the slit portion is periodically lifted to widen the paint outlet through the operating portion that interlocks with the rotation of the wheels of the truck. Since the protrusions are formed on the strip at a predetermined interval by increasing the outflow amount of paint from the road, the road marking line and the protrusions on the line can be formed simultaneously with the same paint, improving workability. Can be made. Moreover, since the formation of the protrusions on the line is performed in conjunction with the rotation of the wheels, a power source for forming the protrusions is not required and the construction can be simplified.

In addition, since the bead-dispersing roll is rotated through the rotation transmission mechanism in association with the rotation of the wheels of the trolley to disperse the glass beads, the beads can be uniformly dispersed, and the power source for the bead-dispersion is I do not need.

Further, when the upper surface of the strip below the small bead sprinkling roll is smooth, the small bead dispersal roll that sprinkles small-diameter glass beads is rotated, and when the protrusion is formed on the upper surface of the strip below the large bead dispersal roll. Large glass beads are sprinkled.Large bead sprinkling rolls are rotated to sprinkle glass beads, so even when it is raining at night, a road marking line with excellent visibility that exhibits the bead reflection effect on the line top projection can be obtained. You can Moreover, since the bead-dispersing rolls are rotated through the rotation transmission mechanism and the intermittent transmission mechanism that are interlocked with the rotation of the wheels of the carriage, the beads can be automatically dispersed and uniformly dispersed.
