Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a road marking device.

(Prior Art) Conventionally, road marking work for drawing division lines and various markings on the road surface has been performed manually. That is, conventionally, a skilled person measures the dimensions in advance and manually draws marks according to markings, etc., and then manually applies paint based on the marks. Conventionally, workers have worked on the road in this way, so there is a risk of a car accidentally driving into them while they are working, and it is also difficult to work when the road surface is uneven. Therefore, attempts have been made to mechanize such road marking work instead of manually.

In order to mechanize road marking work in this way, a mechanism is required to move the paint marking means vertically and horizontally. It consists of an installed vertical guide rail and an axial guide rail movably attached to this guide rail, and a marking means is movably supported on the horizontal guide rail (for example, Japanese Patent Publication No. 58-36682). (see Japanese Patent Publication No. 2003-11-10), and a configuration consisting of a vertical guide rail and a horizontal guide rail that can be attached to and detached from the guide rail, and a marking means is movably supported on the horizontal guide rail ( For example, see Japanese Patent Publication No. 56-31403).

(Problem that the invention aims to solve) Installing a guide rail on a car or having a vertical guide rail and a horizontal guide rail integrated into one is very large and difficult to transport and handle. In addition, miniaturization results in a narrower range that can be marked at one time, which also makes the work cumbersome. In addition, in contrast to the above-mentioned vertical guide rail, there is also one in which the horizontal guide rail that supports the marking means is separable, and the vertical guide rail is made by connecting a pair of left and right guide rails with a connecting member so that they are parallel to each other. Since the pair of left and right wheels provided on the lateral guide rails run on the pair of left and right guide rails supported in a frame-like manner, the structure is relatively simple. There are problems in terms of handling, such as being large-scale, making it difficult to run smoothly if the left and right guide rails are poorly parallel, and being susceptible to road irregularities during installation.

It is an object of the present invention to solve the above-mentioned conventional problems and to provide a road marking device that is extremely easy to transport and handle by rationally configuring a vertical and horizontal movement mechanism.

(Means for Solving the Problems) The means for solving the above-mentioned objects will be explained with reference to the drawings corresponding to the embodiments. and the first guide rail 1.

(Function) In the above configuration, when marking work is performed, first the first guide rail 1 is added in the length direction according to the distance to be marked and installed at a predetermined position on the road. One guide rail 1
The traveling base 2 is attached to the base.

In this state, when the traveling base 2 is made to travel along the first guide rail 1 by the moving means, the second guide rail 3 is moved by the traveling base 2 and the road traveling wheels 6'' on the tip side. First guide rail 1
move in the length direction. Therefore, with this movement,
By moving the marking means 4 along the second guide rail 3 by the moving means and moving the marking means 4 in the longitudinal and lateral directions while being controlled by the respective position detection means, a predetermined marking can be performed. can.

(Example) Next, embodiments of the present invention will be described with reference to the drawings.

In the figure, reference numeral 1 denotes a first guide rail, and this first guide rail 1 is constructed in an angular shape, with one piece on one side serving as a bearing guide 12, and the end edge of the first guide rail 1 having an angled shape. It constitutes a rack part 9. And this first guide rail 1
For example, as shown in FIG. 2, the adjacent portions can be added by connecting the connecting plate 13 and screws. Also, the first guide rail 1
A scale 7 for positioning is provided movably and detachably. Next, code 2 is a running base,
This running base 2 is provided with a running support part that can be attached to and separated from the first guide rail 1 at will. The illustrated traveling support section is composed of a bearing 11 mounted on the bearing guide 12 of the first guide rail 1, a driving wheel 6, and a driven wheel 6'. A second guide rail 3 is provided on the running base 2 in a direction perpendicular to the running direction thereof, and a road running wheel 6'' is provided at the tip of the second guide rail 3. The second guide rail 3 supports a mark means 4 so as to be movable along it, and is provided with moving means and position detecting means for the mark means 4. This moving means is provided with a motor 1.
4. A pulley 15 driven by the motor 14, a pulley 15' paired at a distance from the pulley 15, and a wire wound between the pulleys 15 and 15', with a portion fixed to the marking means 4. It consists of 16. In addition, the position detection means is
It consists of an encoder 8' that rotates in contact with the wire 16. Further, the marking means 4 is configured to spray the paint in the paint tank 10 from a nozzle 20 to apply the paint to the road surface. In addition,
The specific configuration of the marking means 4 is arbitrary. on the other hand,
The means for moving the traveling base 2 includes a motor 5, a pulley 17 driven by the motor 5, and a pulley 1.
A pulley 17' which forms a pair at a distance from 7 and is interlocked with the drive wheel 6, and the pulleys 17,1
It consists of a wire 18 wound between 7',
Further, the position detecting means is the first guide rail 1.
an encoder 8 provided with a pinion 19 that engages with a rack portion 9 formed on the bearing guide 12;
It is composed of: The encoder 8 is not rotated by the engagement of the rack portion 9 and the pinion 19, but may be rotated by pressing a friction roller against the bearing guide 12.

When performing marking work in the above configuration, first the first guide rail 1 is added in the length direction according to the distance to be marked and installed at a predetermined position on the road, and then the traveling base 2 is supported for traveling. The bearing guide 12 of this first guide rail 1
At the same time, the pinion 19 of the encoder is engaged with the rack part 9.

In this state, the traveling base 2 is moved by the moving means.
When the is run along the first guide rail 1, the second guide rail 3 is moved in the length direction of the first guide rail 1 by this running base 2 and the road running wheels 6'' on the tip side. Since the marking means 4 is moved, the moving means moves the marking means 4 to the second guide rail 3 along with this movement.
By moving the marking means 4 in the vertical and horizontal directions while controlling the marking means 4 along the respective position detecting means, predetermined marking can be performed.

(Effects of the invention) As described above, in the present invention, the first guide rail can be freely added to in its length direction, and the second guide rail that movably supports the marking means is
Its one end side is attached to the first guide rail and supported by a detachable running base, and the other end side is supported by road wheels so as to be movable. There is no need for a pair of parallel vertical guide rails on the left and right sides, and there is no need for a frame-like structure with connecting members, making transportation and handling very easy. , it is possible to perform marking work in a wide range of directions at once. Thus, the present invention has the effect of providing a device that can perform road marking work easily and efficiently by mechanizing it instead of manually.
