Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to an automatic spray painting device used to automatically spray paint walls of structures.

[Conventional technology and its problems]

Conventionally, when painting the walls of high-rise buildings or structures with tall and wide surfaces to be painted,
Currently, scaffolding etc. are erected in advance along the walls of structures and spray painting is done manually, which not only involves the danger of working at heights but also takes a lot of time. When I spent a lot of effort, I encountered a problem.

[Purpose of invention]

This invention was made in view of the above-mentioned problems, and the purpose is to provide an automatic spray painting device that can automatically paint the walls of a structure without manual effort.

[Means for solving the problems] In order to solve the above problems, this invention
an automatic traveling cart that horizontally moves the upper surface of the structure parallel to the wall surface of the structure; a guide rail extending downward from the automatic traveling cart parallel to the wall surface of the structure;
The main body of the spray machine is installed on the guide rail so that it can be raised and lowered, and the main body of the spray machine is equipped with a spray nozzle that can swing in the horizontal and vertical directions using a horizontal motor and a vertical motor. It is.

[Effect]

That is, this invention has the above-mentioned structure,
The main body of the spray machine moves vertically and horizontally along the wall of the structure by moving up and down guide rails that move horizontally together with an automatic traveling trolley, and the spray nozzle mounted on the main body of the spray machine swings vertically and horizontally using a horizontal motor and a vertical motor. By spray painting the wall surface while operating, the painting work becomes simple and uniform painting can be performed efficiently.

〔Example〕

This invention will be explained below based on an embodiment shown in FIGS. 1 to 4.

As shown in FIG. 1, reference numeral 1 in the figure is a structure having a vertical wall surface 1a serving as a surface to be painted, and an automatic traveling trolley 2 is installed on top of the structure. The automatic traveling trolley 2 is equipped with devices 3 such as a power source, a spraying material, and an automatic control device using a computer, so that it can run on a track parallel to the wall surface 1a of the structure 1. Further, in the figure, reference numeral 4 denotes a supporter protruding from the automatic traveling cart 2, on which a winder 7 for bundling conduction cables for power, signals, paint, air supply hoses 5, 6, etc. is loaded. A guide rail 8 is vertically suspended in the up-down direction. The guide rail 8
has a spacer 9 made of a roller that rolls in contact with the wall surface 1a of the structure 1 at its hanging end, and the spacer 9 extends the guide rail 8 parallel to the wall surface 1a and at regular intervals. It is adjustably supported by an adjuster 10 for sliding movement. Furthermore, reference numeral 11 in the figure indicates the guide rail 8.
As shown in FIGS. 2 to 4, the main body of the spraying machine is installed so that it can be guided up and down. , held via a nozzle holder 13, and horizontal electric motor 14.
The vertical electric motor 1 enables horizontal rotation at an angle of approximately 90° left and right.
It is possible to vertically rotate at an angle of about 90 degrees up and down through the actuator 16 which rotates by the forward and reverse rotation drive of the structure 1, so that an optimum distance from the wall surface of the structure 1 can always be maintained and the application route can be appropriately guided. In addition, this swinging motion makes it possible to improve the paintability of the uneven portions and details of the wall surface 1a.

The spraying machine main body 11 is powered by an electric motor 1.
The catch gear 20, which is directly connected to the worm wheel 19 which rotates via the worm gear 18 when the gear 7 is activated, is connected to the rack 2 mounted on the guide rail 8.
1, the slider 22 can be moved up and down via a movable slider 22, and the slider 22 slides on the flange portion of the guide rail 8 via upper and lower guide rollers 23, 24. I'm starting to get it. In addition, the spraying machine main body 1
1 tends to become unstable due to the suspension imbalance of the guide rail 8 or the repulsive force caused by the injection pressure of the spray nozzles 12, 12. In order to eliminate this unstable state, the center of gravity position W is changed to the first As shown in the figure, the guide rail 8 is slightly shifted outward by a distance e from the center of the guide rail 8, and the bending stress generates an inward component force so that the guide rail 8 is always pressed against the wall surface 1a, thereby making it smooth. The vertical position is maintained.

Incidentally, the movement of the automatic traveling cart 2, the raising and lowering of the spray machine main body 11, and the rotation of the spray nozzles 12, 12 are all incorporated into the sequence of the control device 3 by a computer, so that they can be controlled.

Furthermore, 25 in the figure is a pressure tank mounted on the spraying machine main body 11, and the spraying material loaded on the automatic traveling trolley 2 is supplied naturally via the paint supply hose 6 depending on the type, or is loaded with excess pressure. This pressure tank 25
The paint P supplied is extruded to the spray nozzles 12, 12 through the paint delivery hose 26, and the paint with sufficient extra pressure is sprayed from the spray nozzles 12, 12 without air, while the viscous The strong paint is sprayed under pressure with compressed air A supplied by an air supply hose 5. Further, the paint P supplied into the pressure tank 25 is agitated by an agitator 27 in order to always maintain a uniform concentration and dispersion state.
In addition to preventing precipitation, the supply of these paints,
The adjustment of the internal pressure of the pressure tank, the extrusion of paint from the spray nozzle, and the supply of compressed air are also all controlled based on the sequence of the control device 3 by computer.

That is, this invention raises and lowers the spraying machine main body 11 up and down on the guide rail 8 installed parallel to the wall surface 1a of the structure 1, and
is suspended from the automatic traveling trolley 2 via the supporter 4, and by moving the automatic traveling trolley 2 parallel to the wall surface 1a, the spraying machine main body 11 is regularly moved vertically and horizontally using the entire wall surface as a working range. The spray nozzles 12, 12 attached to the spray machine main body 11 are arranged so that the paint P can be automatically applied to the entire front surface in all directions to uniformly paint the wall surface, and the two are arranged as a pair. The automatic control device 3 controls the spray nozzles 12, 12 to simultaneously cause similar operations or each independent operation, thereby making it possible to efficiently apply uniform coating to the spraying area at each fixed point, and furthermore, the paint P
An airless spray device that automatically controls the opening and closing of the spray nozzles 12, 12 to which paint is supplied at high pressure to spray the paint in the form of a spray, and a device that assists compressed air to adjust the spray force of the paint. This makes it possible to generate a spray that matches the properties of the spray.

In the above embodiments, a structure with vertical walls has been described as an example, but it is of course applicable to a structure 1 having an inclined wall 1a as shown in FIG. In addition, as a means of running the automatic traveling trolley, means such as rail running or electromagnetic induction running can be considered.
The selection is arbitrary.

[Effect of idea]

As is clear from the above explanation, this idea is
The structure allows spray painting to be applied to walls of vertical or inclined structures by moving the main body of the spraying machine regularly in parallel up and down, left and right, and by swinging the spray nozzle vertically and horizontally. This has the advantage that dangerous manual work at high places can be eliminated, and the wall surface can be coated uniformly, and uneven parts and details of the wall surface can also be painted well.
