Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an apparatus for painting the inner surface of a narrow and long groove formed in the vertical direction on the outer wall of a building.

[Conventional technology]

BACKGROUND ART In some cases, a long narrow groove is formed in the outer wall of a building, which serves as a guide rail for guiding a gondola when cleaning windows, for example.

Conventionally, painting the inner surface of such grooves has mostly been done by hand by painters.

Additionally, with the recent development of mechatronics technology, there is a trend towards automating the painting of such parts.

[Problem that the invention attempts to solve]

However, this traditional hand-painting work by painters is dangerous at high places, and
Problems were that the work efficiency was poor, it took a long time, and the quality of the painting was low.

Furthermore, even when attempting to automate painting, there is a problem in that it is almost impossible to prevent mist from scattering if current automatic painting equipment is used as is.

This idea was created by focusing on these conventional problems, reducing the need for work at heights, achieving quick and high-quality painting, and creating a building that eliminates the scattering of mist. The object of the present invention is to provide a coating device for a groove on an exterior wall of a property.

[Means for solving problems]

Therefore, the coating device for a building exterior wall groove according to this invention includes a box that can move the front surface of a groove vertically formed in the exterior wall of a building while being guided by the groove, and a case that can paint the inner surface of the groove. a spray gun mounted on the box, and a spray gun having a shape similar to the cross-sectional shape of the groove, and mounted on the upper and lower parts of the box above and below the spray gun mounting position of the box. It contacts the inner surface of the unpainted part of the groove on the front side in the direction of movement of the box, and moves with the case with a gap between the inner surface of the painted part of the groove on the rear side in the direction of movement of the case. At least one partition plate.

[Effect]

While moving the box along the front surface of a groove vertically formed on the exterior wall of a building, a coating device paints the inner surface of the groove. The partition plate on the front side in the direction of movement of the box moves with the case while contacting the inner surface of the unfinished part of the groove, so the sprayed paint mist is reliably prevented from scattering, and the partition plate on the rear side in the direction of movement of the box moves with the case. Since the partition plate moves with the box with a gap between it and the inner surface of the already installed part of the groove, it almost certainly prevents paint mist from scattering, and also prevents the occurrence of scratches on the painted inner surface. Peeling of the film is prevented.

〔Example〕

Hereinafter, embodiments of this invention will be described with reference to the drawings.

First, the configuration will be explained.

In FIG. 1, reference numeral 1 denotes an outer wall of a building, on which a groove 2, such as a guide rail, which is narrow and long in the vertical direction and whose cross section is approximately T-shaped, is formed.

Reference numeral 3 denotes a box for the coating device, and this box 3 is attached via a bracket (not shown) below a carrier 4 that moves up and down along the outer wall of the building. As the box 3 moves up and down along the groove 2, the box 3 is guided by the groove 2 at the front surface of the groove 2 and can move in the vertical direction.

Note that the coating device including the box 3 can be guided by the conveyor 4 into the groove 2 and moved in the vertical direction, but in the embodiment described here, the coating work is performed when the box 3 is raised. It is something. (It is also possible to perform the painting work when the box 3 is lowered, but this will be described later.) As shown in Figures 1 to 4 (particularly Figure 2),
The box 3 has a box center part 3a in the center part in the vertical direction.
, an upper part 3b of the box, and a lower part 3c of the box below the central part 3a of the box.

The central part 3a of the box has a back plate 3d arranged parallel to the front surface of the groove 2, and a surface facing the groove 2 by surrounding the vertical direction between the back plate 3d and the front surface of the groove 2 with a plate. is configured so that it opens. A painting device such as a spray gun 5 is attached to the back plate 3d, and paint can be sprayed from the spray gun 5 toward the opening of the central portion 3a of the box.

In addition, the bottom plate 3e of the central part 3a of the box is a back plate 3d.
It is tilted from the side toward the opening, so that the mist on the paint adhered to the inside of the case center portion 3a flows toward the opening along the bottom plate 3e.

The upper part 3b of the box has a contact plate 3f that contacts at least the front surface of the groove 2.

Moreover, the lower part 3c of the case has at least a contact plate 3g that similarly contacts the front surface of the groove 2 and a space portion 3h below the contact plate 3g.

Therefore, while the contact plate 3f of the upper part 3b of the case and the contact plate 3g of the lower part 3c of the case are in contact with the front surface of the groove 2, the case 3 is moved up and down by the conveyor 4 on the front surface of the groove 2. move up and down.

Two first partition plates 6 and 7 are fixed to the front surface of the abutting plate 3f of the upper part 3b of the case, and these first partition plates 6 and 7 are inserted into the groove 2 and are inserted into the groove 2. It is movable together with the box 3 in the vertical direction inside. That is, these first partition plates 6 and 7
Both are made of approximately T-shaped substrates 6a, 7a having a certain amount of clearance from the inner surface of the groove 2 and similar in cross-sectional shape to the groove 2, and a flexible material fixed around the substrates 6a, 7a. buffer materials 6b, 7
b, and when the first partition plates 6, 7 are inserted into the groove 2, the outer circumferences of the cushioning materials 6b, 7b are formed in close contact with the inner surface of the groove 2.

Also, four second partition plates 8, 9, 10, 11 are fixed to the contact plate 3g of the lower part 3c of the box 3, and the second partition plates 8 to 11 are also connected to the first partition plate 3g. Like the partition plates 6 and 7, it is inserted into the groove 2 and
It is movable together with the box 3 in the vertical direction inside the box.

That is, as shown in FIGS. 5 to 7, these second partition plates 8 to 11 (partition plates 9 to 11 are not shown) all have a considerable gap from the inner surface of the groove 2. , a substantially T-shaped substrate 8a similar to the cross-sectional shape of the groove 2, and a cushioning material 8b made of a flexible material fixed around the substrate 8a...
..., and when the second partition plates 8 to 11 are inserted into the groove 2, the outer periphery of the cushioning material 8b... is formed so as to have a gap between it and the inner surface of the groove 2. The size of the gap is determined by the size of the gap between the box 3 and the groove 2.
The width of the sway should be greater than the amount of sway when moving along the

Further, each of the second partition plates 8 to 11 is sloped such that the center portion in the width direction of the groove 2 (A-A direction in FIG. 5) is low and becomes higher toward both sides thereof (FIG. 7). ), and the groove 2 is sloped in the depth direction (B-B direction in FIG. 6) so that it becomes lower as it goes toward the box 3 side. The three second partition plates 8 to 10 other than the lowest second partition plate 11 among the four second partition plates 8 to 11 are A through hole 8c and a through hole 8d are formed in the middle of the box and at the base of the lower part 3c of the box to the contact plate 3g.

Due to the inclination of the second partition plates 8 to 11 and the through holes 8c and 8d, the second
The mist adhering to the partition plates 8 to 11 is collected at the base of the contact plate 3g at the widthwise center of the lowermost second partition plate 11.

As shown in FIGS. 2 and 3, a paint discharge port 12 is provided at the lowest part of the lower part 3c of the case, and this discharge port 12 is connected to a tank (not shown) outside the case 3. ing.

The coating device is thus configured.

Next, the operation of the above embodiment will be explained.

First, the first partition plates 6 and 7 and the second partition plates 8 to 11 fixed to the case 3 of the coating device are inserted into the groove 2 on the roof of the building.

Next, the coating device is once moved along the groove 2 by the carrier 4 and lowered to the ground, and then the coating device is lifted up by the carrier 4. During this upward movement, paint is sprayed from the spray gun 5 to paint the inner surface of the groove 2 between the first partition plate 7 and the second partition plate 8 from the opening of the central part 3a of the box.

When painting while raising the painting device in this way, the upper part of the groove 2 where the paint is sprayed from the spray gun 5, that is, the part on the front side in the direction of movement, which will be painted from now on, is , the cushioning material 6b of the two first partition plates 6 and 7,
Since the outer periphery of the groove 7b rises while contacting the inner surface of the groove 2, mist is prevented from leaking above the first partition plates 6 and 7 and being scattered.
Since two first partition plates are provided, mist scattering can be reliably prevented.

Further, the cushioning materials 6b and 7b prevent the substrates 6a and 7a from being damaged by hitting the step when there is a step on the inner surface of the groove 2 at the joint part of the PC board.

Further, the mist adhering to the bottom plate 3e of the central part 3a of the box flows toward the opening and passes through the second partition plate 8.
Flows down onto the top surface.

On the other hand, when painting is carried out while the painting device is raised, the painting has already been completed in the lower part of the groove 2 where paint is sprayed from the spray gun 5, that is, on the rear side in the direction of movement. The portion 4 is arranged with a gap from the inner surface of the groove 2.
The second partition plates 8 to 11 substantially, but not completely, prevent the mist from leaking downward and scattering.
The gap between the inner surface of the groove 2 and the second partition plate 8 to 11 is set so that even if the box 3 shakes while rising, the second partition plates 8 to 11 do not come into contact with the inner surface of the groove 2, which has been painted. The coating equipment rises without scraping the surface.

The cushioning material 8b of each of the second partition plates 8 to 11 is
Similar to the cushioning materials 6b and 7b of the first partition plates 6 and 7, if there is a step on the inner surface of the groove 2 at the joint part of the PC board, it is possible to prevent the board 8a from hitting the step and being damaged. To prevent.

The mist adhering to the upper surface of the second partition plate 8 on the uppermost stage is moved from the widthwise center of the second partition plate 8 to the base of the box 3 according to the slope formed on the second partition plate 8. The bottom plate 3e of the central part 3a of the box
The through-hole 8c formed in the second partition plate 8 along with the mist that has flowed down onto the upper surface of the second partition plate 8.
And it flows down from 8d to the upper surface of the second partition plate 9 below.

The paint that has fallen onto the top surface of this second partition plate 9,
The mist that leaks through the gap between the second partition plate 8 and the inner surface of the groove 2 and adheres to the upper surface of the second partition plate 9 is formed on the second partition plate 9 by the same action as described above. It gathers from the center part in the width direction of the second partition plate 9 to the base part of the box 3 according to the inclination, and from the through hole (not shown) formed in the second partition plate 9, the second part further below. It flows down onto the upper surface of the partition plate 10.

The paint that has fallen onto the top surface of the second partition plate 10 and the mist that has leaked through the gap between the second partition plate 9 and the inner surface of the groove 2 and adhered to the top surface of the second partition plate 10 are similar to those described above. Due to this action, the particles gather from the widthwise center of the second partition plate 10 to the base of the box 3 according to the slope formed on the second partition plate 10, and are formed on the second partition plate 10. The water flows down from the through holes (not shown) onto the upper surface of the second partition plate 11 at the bottom.

The paint that has fallen onto the top surface of the second partition plate 11 at the bottom, and the slight mist that has leaked through the gap between the second partition plate 10 and the inner surface of the groove 2 and adhered to the top surface of the second partition plate 11, By the same action as described above, the second partition plate 11 gathers from the widthwise center part of the second partition plate 11 to the base part of the box 3 according to the inclination formed on the second partition plate 11, and furthermore, the lower part 3c of the box space part 3
h to the discharge port 12 and a tank (not shown).
is discharged and collected.

In this way, the coating device 4 moves up along the groove 2 in front of the groove 2 while painting the inner surface of the groove 2, and scatters the mist onto the two first partition plates 6, 7 and 4 second partition plates 8~
11, and the mist is collected and discharged.

In the above-described embodiment, the painting is performed when the painting device is moved up along the groove of the outer wall of the building by the conveyor, but the painting may be performed when the painting device is lowered. In this case, the box is attached to the top of the carrier, and the first partition plate, which is arranged so that there is no gap between the two and the groove, is located at the front side in the direction of movement of the box relative to the installation position of the spray gun. The second partition plate, which is fixed to the lower part of a certain box and is arranged with a gap from the groove, is fixed to the upper part of the box which is on the rear side in the moving direction of the box from the mounting position of the spray gun. The slope and through-hole for collecting the mist are formed in the lower first partition plate.

In addition, the first partition plate has two pieces, and the second partition plate has four pieces.
Although the number of partition plates is shown as two, the number of partition plates is not limited to this, and an appropriate number of partition plates may be used as long as the scattering of mist is prevented. In particular, the number of second partition plates is increased as the vibration of the box increases and the gap becomes larger.

Furthermore, although the first partition plate and the second partition plate are fixed to the case 3, they may be detachably attached to the case.

[Effect of idea]

As explained above, the coating device for a building exterior wall groove according to the present invention includes a box that is movable along the front surface of a groove formed in the vertical direction on the exterior wall of a building while being guided by the groove; a spray gun attached to the box so as to be able to paint the inner surface; an upper part of the box and a box having a shape similar to the cross-sectional shape of the groove and above and below the spray gun mounting position of the box; Attached to the bottom of the box, it contacts the inner surface of the unpainted part of the groove on the front side in the direction of movement of the box, and leaves a gap on the inner surface of the painted part of the groove on the rear side in the direction of movement of the box. Since the construction is equipped with at least one partition plate that moves with the body, it is possible to automatically paint the inner surfaces of narrow and long grooves on the exterior walls of buildings, reducing work at heights and quickly. Not only can a high-quality coating be obtained, but also the scattering of mist can be more reliably prevented on the front side in the direction of movement of the box and almost certainly on the rear side in the direction of movement of the box. The effect is that no scratches or peeling of the paint film will occur on the inner surface of the groove.
