[First Embodiment]

Hereinafter, the painting tool of the present invention will be described with reference to the first embodiment shown in FIGS.

1 is a front view of a painting tool of the present invention, FIG. 2 is a vertical cross-sectional view taken along the line CC of FIG. 1, FIG. 3 is a plan view of the painting tool, and FIG. 4 is a diagram showing a piping system of a cylinder. Gram.

As shown in Figs. 1 to 3, the painting tool of the present invention has a first reciprocating mechanism 1, a painting tool support member 2 and a second reciprocating mechanism (a cylinder having a bellows and no rod). (3), a painting spray gun (4), a hood (14) composed of a first hood (7), a second hood (8), and a third hood (9), and a suction nozzle (11).

The painting tool support member 2 is attached to a working device (wall working device) not shown. Such a wall work device, for example, has a work truck 201 of the prior art reflected in FIGS. 8 to 10. Preferably such work trucks are autonomous trucks that move on the paint surface remotely with wheels for moving on the painted surface of the structure and magnetic and other devices for holding the truck on the magnetic surface to be painted.

The first reciprocating mechanism 1 is formed of a cylinder mechanism composed of an air cylinder (fixing part) 1a and a piston rod (moving part) 1b. The air cylinder (hydraulic cylinder) 1a of the first reciprocating mechanism 1 is fixed to the painting tool support member 22, and the piston rod 1b is the painted surface 10 of the structure, as indicated by arrow A in FIG. Is applied to reciprocate in a direction perpendicular to or in other directions (movement direction toward or away from the paint surface 10).

The bracket 6 is also fixed to the piston rod 1b of the first reciprocating mechanism 1 and the bracket 5 is further fixed to the bracket 6. As shown in FIG. 3, the bracket 5 is larger than the entire length of the second reciprocating mechanism 3. The brackets 12 are fixed at both ends of the bracket 5, respectively.

The second reciprocating mechanism 3 is composed of a moving part 3a and an elastic part (elastic bellows) 3b and 3c. Each elastic portion 3b, 3c has an air inlet and an air outlet (not shown).

The painting spray gun 4 is attached to the moving part 3a of the second reciprocating mechanism 3 via the bracket 13. The outer ends of the bellows 3b and 3c of the second reciprocating mechanism 3 are fixed to the brackets 12 and 12, respectively. Painting with the moving part 3a while supplying air to one of the bellows 3b, 3c to inflate the bellows 3b, 3c, and discharging air from the other to deflate the bellows 3b, 3c. The spray gun 4 reciprocates in the direction indicated by arrow B in FIG. 3. That is, they move back and forth parallel to the paint surface 10 of the structure.

The first hood 7 is attached to the bracket 5 on the piston rod 1b side of the first reciprocating mechanism and covers the top of the second reciprocating mechanism 3, thereby spraying from the painting spray gun 4. Prevents paint from dispersing outside.

A second hood 8 is attached to the painting tool support member 2 to surround the lower part of the second reciprocating mechanism 3, thereby preventing the paint sprayed from the painting spray gun 4 from dispersing outwards.

The third hood 9 is an elastic bellows hood disposed between the first hood 7 and the second hood 8 and also prevents paint sprayed from the painting spray gun 4 from dispersing outwards.

A suction nozzle 11 is attached to the first hood 7 and is connected to an aspirator (not shown) to suck paint mist from within the first hood 7 to the third hood 9.

As shown in FIG. 4, the air cylinder 1a of the first reciprocating mechanism 1 is an air supply source via pipes 19a, 19b, 26, solenoid valve 17, and pressure reducing valve 30. It is connected to 35. Under remote control, the solenoid valve 17 is operated by a switch (switch operation of the connection state of the pipes 19a and 19b to the pipe 26) to move the bracket 65 and the second reciprocating mechanism 3 up and down. Let's do it. As shown in Fig. 4, when the solenoid valve 17 is turned off, the pipes 26 and 19b communicate with each other so that the bracket 6 descends along the piston rod 1b.

The second reciprocating mechanism 3 (the bellows 3b, 3c is connected to the air supply 35 via the pipes 20a, 20b, 27, the solenoid valve 16, and the pressure reducing valve 29). Under remote control, the solenoid valve 16 switches the connection of the pipes 20a, 20b to the switch operation (pipe 27) so that the painting spray gun 4 reciprocates parallel to the paint surface 10 of the structure. Exercise.

The spray gun 4 is connected to the air supply 35 via pipes 33, 34, solenoid valve 32, and pressure reducing valve 31. The solenoid valve 32 is simultaneously switched to match the reciprocating timing of the second reciprocating mechanism 3 (pipes 33 and 34 selectively communicate with each other or disconnect). Spray paint from (4) and as a result the paint surface 10 of the structure is painted.

With this specification, the painting tool of the first embodiment paints with a painting spray gun 4, which is otherwise worked by a wall work device not depicted. Here the painting tool itself moves the paint surface 10 together with the wall work device, where the solenoid valve 16 is suitably switched to actuate the second reciprocating mechanism 3 and the painting spray gun 4 It reciprocates parallel to the paint surface 10.

Thus, this movement of the painting tool with the moving wall work device and the movement of the painting spray gun 4 by the second reciprocating mechanism 3 are connected to each other, while the paint surface with the single painting spray gun 4 is also connected. Can paint the wide side of (10).

The painting spray gun 4 can spray paint when the solenoid valve 32 is actuated to communicate the pipes 33 and 34 with each other to supply air to the painting spray gun 4. When the second reciprocating mechanism (3) reciprocates the painting spray gun (4), the solenoid valve (32) operates simultaneously with the timing of the reciprocating motion to adjust the air supply to the painting spray gun (4) to paint spray operation. Adjust As a result, the paint surface 10 can be painted uniformly.

In addition, the solenoid valve 17 is switched so that the first reciprocating mechanism 1 can be operated as needed, thereby adjusting the vertical position of the painting spray gun 4.

Thus, even if there is an obstruction on the path of the painting tool, the painting spray gun 4 can lower its position to avoid obstruction of the obstruction, thereby increasing its movement area in spite of the obstruction and also the painting area. Also increases.

The hood 14 also includes a first hood 7 attached to the moving part (piston rod) 1b of the first reciprocating mechanism 1 and a first hood 8 attached to the painting tool support member 2. And a third hood 9 disposed between the first hood 7 and the second hood 8, and because the third hood 9 is an elastic material, the lower end of the hood 14 and The distance between the paint surfaces 10 can be kept constant even when the first reciprocating mechanism 1 operates to move the painting spray gun 4 up and down.

As a result, the hood 14 protects the paint surface 10, while reliably preventing paint sprayed from the paint spray gun 4 from dispersing outside the hood 14. In addition, the fat mist in the hood 14 can be reliably sucked and collected by the suction nozzle 11.

The result is an improvement in the use of paint by ensuring that only the required paint surface is painted without spraying the areas where painting is not needed.

Although the solenoid valves 16 and 17 are simple on / off switch types, their working capacity can be improved when the air supply and discharge stop modes are provided in addition to the air supply mode and the air discharge mode.

In addition, solenoid valves 16 and 17 may be duty-controlled. In this case, when the solenoid valve 16 is duty controlled, the second reciprocating mechanism 3 can move or stop in a given direction at an appropriate speed. On the other hand, when the solenoid valve 17 is duty controlled, the first reciprocating mechanism 1 can also move or stop in a given direction at an appropriate speed.

Second Embodiment

5 shows a painting tool according to a second embodiment of the invention. In this embodiment, the first reciprocating mechanism 50 has two cylinder mechanisms (reciprocating mechanisms) 51 and 52, each of which is, like the cylinder mechanism 1 of the first reciprocating mechanism of the first embodiment, air Cylinder (stop) 51a, 52a and piston rod (moving part) 51b, 52b are included.

In the first cylinder mechanism 51, like the first reciprocating mechanism 1 of the first embodiment, the bracket 6 is fixed to the piston rod 51b and similarly to the first embodiment, the second reciprocating mechanism 3 is A bracket 5 fixed to the bracket 6 and a bracket 12 fixed to the bracket 5 are connected to each other.

On the other hand, in the second cylinder mechanism 52, the air cylinder 52a is fixed to the painting tool support member 2, the bracket 56 is fixed to the piston rod 52b, and the bracket 55 is the bracket 56. Is fixed to the piston rod 52b via the brackets 55 and 56.

In this embodiment, since the first reciprocating mechanism 50 can move vertically in a wider range, the painting tool can lower its height further. For example, assuming that the first and second cylinders 51 and 52 are the same, S1 = S2. In the case where only one cylinder mechanism is provided (ie, the first embodiment), the height of the painting spray gun 4 is H + S1.

When the length L of the air cylinder decreases by α, the height of the painting spray gun 4 is H-α + S1-α = H + S1-2α. The height of the painting tool is L-α.

By adding and attaching the same cylinder, the height of the painting spray gun 4 becomes H + S1-2α + S1-α.

When S1-α> 2α, the original height of the painting spray gun 4 can be secured. As a result, when α is S1> 3α, the height of the painting tool can be lowered by α, thereby securing the height H + S1 of the painting spray gun 4.

Although the first reciprocating mechanism, in which the moving part reciprocates in a direction toward or away from the paint surface, is configured such that only two cylinder mechanisms (reciprocating mechanisms) 51 and 52 are connected together in this embodiment, more cylinder mechanisms ( The reciprocating mechanism may similarly be further connected.

Also in each embodiment, although one or a plurality of air cylinder mechanisms are provided as the first reciprocating mechanism, other fluid pressure cylinder mechanisms such as hydraulic cylinders as well as the air cylinder mechanism may be used as the first reciprocating mechanism. have. In addition, other mechanisms may be used, such as cylinder mechanisms as well as reciprocating mechanisms using electric motors.

Similarly, although air pressure is used as the second reciprocating mechanism for driving the moving part in each embodiment, other fluid pressures such as hydraulic pressure may be used. Other mechanisms may also be used, such as reciprocating mechanisms using electric motors as well as fluid pressure mechanisms.

Although the hood 14 is a configuration in which the first hood 7, the second hood 8, and the third hood 9 are connected together in each embodiment, the configuration of the hood 14 is not limited to this alone. In other words, the hood 14 may be constituted only by an elastic hood such as the third hood 9. The hood 14 may also be of a configuration in which the first hood 7 and the second hood 8 overlap one another, and their overlap length may be varied so that the hood 14 may have a varying length.
