Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automatic coating device used to automatically apply upward coating to a surface to be coated, such as the bottom shell of a ship.

[Prior Art] For example, the bottom and side panels of a ship built in a dock are painted as required, but
Painting on the bottom of the ship must be done in an upward position in the dock.

Conventionally, the painting work applied to the bottom outer panels of ships built at docks has mainly been done manually by workers, and in reality, the painting is done using brushes.

[Problem to be solved by the invention] However, in the conventional method of manually painting the bottom shell of a ship in the dock, the thickness of the paint film tends to be uneven depending on the location, and it is difficult to make the paint film thickness uniform. requires a high degree of skill, and in practice it is difficult to achieve a uniform coating thickness by hand, and the coating must be done in an upward position.
There were also difficulties in the workability of painting.

SUMMARY OF THE INVENTION Therefore, the present invention aims to provide an automatic painting device that automates the painting of the bottom shell of a ship, makes it easy to achieve a uniform coating film thickness, and allows the painting work to be performed with high efficiency. That is.

[Means for Solving the Problems] In order to solve the above problems, the present invention provides a means for solving the problems described above.

A rail for gun direction change is installed, and a drive device for running the truck and a traversing drive device for the coating machine are installed so that when the truck moves forward and stops, the coating device moves along the guide rail and performs painting. Link.

[Operation] When carried to a position below the surface to be coated, the coating machine on the guide rail is reciprocated along the guide rail to coat in the left and right direction. When the reciprocating motion of the coating machine stops, the traveling truck is moved forward and then stopped, and the coating machine is moved laterally again to coat a portion of the coating in a lapped state.

In the above, when the coating machine comes to the guide rail and stops, the spray gun is turned from upward to diagonally outward to prevent the coating film from increasing in thickness at the folded portion.

[Example] Embodiments of the present invention will be described below with reference to the drawings.

A guide rail 5 with a C-shaped cross section extending horizontally in the left-right direction is installed on the upper surface of the trolley 1 connected to the trolley 1 so as to be movable up and down with a lifting jack 6. The guide rail 5 is guided by a guide device 7 that allows the guide rail 5 to move only in the vertical direction,
Moreover, on the guide rail 5, a paint g 18 is installed, which is a movable body 9 with a spray gun 10 attached upward and swingable in the left and right directions. The above moving body 9
The spray gun 10 is made to be able to move freely on the guide rail 5, and when the spray gun 8 reaches both ends of the guide rail 5, the spray gun 10 is automatically swung from upward to diagonally outward.

Specifically, the coating machine 8 includes a movable body 9 to which a guide roller 12 is attached so as to roll along the upper and lower surfaces and the front and rear surfaces of the guide rail 5, and a screw 31 attached to the movable body 9.
A spray gun 10 is attached so as to be able to swing in the left and right direction at the same time, and an arm 14 is integrated with a guide roller 15 that moves on a guide rail 5 at both ends to regulate the direction of the spray gun 10. Spray gun 1 formed by fixing the central part of vertical bar 16 to spray gun 10
0, the spray gun 1
One end of a hose storage hanger 18 for storing the paint hose 17 connected to the spray gun 10 is fixed to the lower end of the vertical bar 16 of the direction regulating device 13 of The hose 17 and the hanger 18 are enabled to follow and move together when moving in the left and right direction.

Furthermore, a spray gun deflection rail 19 having an arcuate guide surface 20 is extended downward and fixed to both ends of the guide rail 5, and the left or right end of the guide rail 5 is painted. When machine 8 moved, spray gun 1
The guide roller 15 of the direction regulating device 13 runs along the guide roller 20 of the rail 19, so that the direction regulating device 13 is tilted, and at the same time, the spray gun 10 can be swung from upward to diagonally outward. Make it.

A chain 11 is disposed along the inside of the guide rail 5 in order to reciprocate the painting tool 8 in the left and right direction, and a chain sprocket 2 is supported on both sides of the guide rail 5.
1.22, its both ends are fixed to the movable body 9 of the coating machine 8, and the middle part is fixed to the notch 2 of the guide rail 5.
3 through a sprocket 24, and is hooked around a chain sprocket 26 on the output shaft of a motor 25 installed on the top surface of the truck 1, and the chain 11 is moved by the drive of the motor 25, and the coating machine 8 is rotated. The coating machine 8 can be moved automatically on the guide rail 5, and limit switches 2 for moving the coating machine 8 are installed at both ends of the guide rail 5.
7 is installed, and when the operating piece 28 (see Fig. 3) that protrudes from the movable body 9 of the atomizer 8 comes into contact with the limit switch 27, the limit switch 27 is activated, and the atomizer 8 is activated.
The limit switch 27 and the motor 25 are interlocked so that the movement of the dolly 1 is automatically stopped, and the motor 25 is interlocked so that the movement of the trolley 1 and the movement of the coating machine 8 are alternately performed. 25 and the drive device 4 of the truck 1 are interlocked so that the truck 1 automatically runs and paints.

Note that l supplied to the spray gun 10 of the coating machine 8 is
The paint is pumped from within a tank 29 installed on the truck 1, and the pump may be automatically driven when the paint sprayer 8 moves. 30
is the guide rail 5 for receiving the hose storage hanger 18.
This is a hanger holder fixed at a lower position.

When painting a flat object, such as the bottom shell of a ship, the trolley 1 is moved to the lower part of the surface to be painted, and then the lifting jack 6 is operated to move the object onto the guide rail. 5 is set at a predetermined height, and furthermore, the motor 25 is driven to position the coating machine 8 via the chain 11 at either the left or right end of the guide rail 5. In this state, the motor 25 is driven to cause the paint machine 8 to move laterally along the guide rail 5, and the paint is ejected upward from the spray gun 10 onto the surface to be painted. When the coating machine 8 linearly coats the desired width in the left and right direction and reaches the end of the guide rail 5, the movable body 9 of the coating machine 8 activates the limit switch 27 to stop the motor 25. Therefore, the coating machine 8 is stopped at the end of the guide rail 5. At this time, if the paint is ejected from the spray gun 10 and sprayed onto the surface to be painted while the paint machine 8 is stopped, the thickness of the paint film in that area will become thick and uneven, so the spray gun 10 will be turned off. Shake it around to prevent the paint film from getting thicker. This oscillation of the spray gun 10 is caused by the fact that when the II machine 8 comes to the end of the guide rail 5, the leading guide roller 15 of the direction regulating device 13 of the spray gun 10 moves toward the rail 1 for changing the direction of the spray gun.
9 and below the upper surface of the guide rail 5, the direction regulating device 13 as a whole is rotated outward relative to the movable body 9, thereby automatically rotating the direction regulating device 13. As a result, when the paint sprayer 8 comes to the end of the guide rail 5 and stops, the spray gun 10 is automatically swung from an upward position to a diagonally outward position, increasing the thickness of the coating film at one location. is prevented.

When the sprayer 8 comes to the end of the guide rail 5 and stops as described above, the trolley 1 is automatically moved a preset distance.
That is, it is moved forward by an amount that partially wraps the painted surface and then stopped again. When the platform 1 is stopped, the motor 25 is restarted and rotated in the opposite direction to the previous rotation to move the coating machine 8 through the engine 11 to the guide rail 5.
This is done by spraying the paint onto the surface to be painted using the spray gun 10 while moving along the direction. When the sprayer 8 reaches the end of the guide rail 5 in this way, the sprayer 8
The movement of the spray gun 10 is automatically stopped by the operation of the limit switch 27, and at the same time the spray gun 10 is changed from an upwardly facing position to an obliquely outwardly facing position.

Thereafter, as described above, the slight advance of the trolley 1 and the reciprocating movement of the coating machine 8 on the guide rail 5 are alternately and automatically carried out, so that the upward coating on the surface to be coated has a uniform coating film thickness. It will be held in ．． In the above, the hose 17 connected to the spray gun 10 is made to follow the movement of the sprayer 8, but it is stored in the hose storage hanger 18, and the hanger 18 is received by the hanger receiver 30 and moves. , kept safe.

Note that the present invention is not limited to the above-mentioned embodiments; for example, the spray gun 10 of the coating machine 8 is rotated by the direction regulating device 13 and the rail 19 for changing the direction of the spray gun. It goes without saying that the spray gun 10 may be directly engaged with the rail 19, and that various other modifications can be made without departing from the gist of the present invention.

[Effects of the Invention] As described above, according to the automatic painting apparatus of the present invention, a guide rail extending parallel to the left and right directions is installed on a self-propelled trolley so that it can be raised and lowered by a lifting device, and the painting device is moved to the guide rail. A paint machine, which is made up of a movable body that is freely assembled, is rotatably attached so that the spray gun can be swung left and right with the spray gun facing upward, is mounted on the guide rail so as to be able to move horizontally, and on both ends of the guide rail, A rail is attached to swing the sprayer, and the drive device that moves the sprayer horizontally on the guide rail is linked with the drive device of the trolley, so that when the trolley moves forward and stops, the sprayer moves along the guide rail. Paint is applied by spraying paint from a spray gun while moving horizontally, and when the paint machine stops at the end of the guide rail, the trolley is moved forward. Painting is automatically performed in a straight line in the left and right direction, making it possible to achieve uniform coating film thickness.Also, when the coating machine, which moves back and forth on the guide rail, comes to the end of the guide rail, the coating is automatically applied. Since the direction of the spray gun is directed outward, it is possible to prevent the coating film from becoming thicker at the edges, which has the excellent effect of realizing highly accurate coating.
