Abstract

PURPOSE:To automate a painting operation in painting a roof made of metallic folded plate, by making a carriage travellable with the projecting line parts of the roof as rails and making wheels movable in the axle direction. CONSTITUTION:The projecting line parts 1a of a roof 1 is used as rails for a carriage 2. While the carriage 2 is moved along the parts 1a, a paint is ejected from the oscillating spray nozzles 16 of a spray type coater 11 mounted on the carriage, whereby the parts 1a and both lateral wall faces 1a' of the roof 1 as well as the entire surface in the groove parts 1b are painted automatically and uniformly. When the carriage 2 comes to the terminal of the roof 1 along the parts 1a serving as rails, guide rails 29 are disposed below wheels 24 for traversing so as to intersect orthogonally with the parts 1a and the wheels 24 are placed on the rails 29; at the same time, traveling wheels 3 are floated together with the carriage 2. Thereafter, the carriage 2 is moved transversely to the position above the parts 1a to be used as the next rails by using the wheels 24.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic roof coating machine constructed using folded metal plates having a trapezoidal or V-shaped cross section.

Roofs made of the above metal folded plates are often used in structures with large roof areas, such as factories, warehouses, and station buildings. Conventionally,
Applying anti-corrosion coatings to such roofs has been left entirely to manual labor. However, as mentioned above, the roof area is generally vast, and the entire roof has many uneven lines, making it difficult to paint, making the painting process very expensive. Ta. Therefore, there has been a desire for an automatic coating machine that can efficiently coat roofs made of folded metal plates at a low cost, but it has not yet been commercially available.

The present invention was developed in response to such demands, and an object of the present invention is to provide a traveling automatic roof coating machine that can automatically and efficiently coat folded metal plate roofs.

In order to achieve the above object, the present invention uses parallel protrusions of a roof constructed using folded metal plates having a trapezoidal or V-shaped cross section as rails, and wheels that roll along the protrusions. A drive device for driving the wheels, a spray coating device, and a rocking device for an injection nozzle of the spray coating device that is swingably attached to the trolley are mounted on a trolley having The vehicle is characterized in that the wheel is attached to the axle thereof so as to be movable in the axial direction.

Hereinafter, one embodiment of the present invention will be described based on the drawings. 1
is a roof made of folded metal plates with a trapezoidal cross-sectional shape, and has many protrusions (mountains, 11a) and grooves (valleys) extending in parallel.
b are formed alternately in parallel. Reference numeral 2 denotes a trolley that forms the main body of the coating machine, and checkerboards 3.3' are provided at the four corners of both the front and rear sides. Wheels 3. The holder has a flange 3a on both sides, and the flange 3a abuts against both 111 slopes 1a of the protrusion 1a and is mounted so as to straddle the protrusion 1a, and extends along the protrusion 1alC. When rolling, the folded plate attachment can pass through the bolt 30 without contacting it, as shown in FIG.

One wheel 3 on one side is wedged via a key 6 to an axle 5.6' which is rotatably supported at the bottom of the bogie 1 via a bearing 4, and the number of cars is 11111. 3° and 3' are mounted on two parallel protrusions 1a, and the carriage 2 can run along the protrusions 1a using the protrusions 1a as rails. In this case, the wheel 3 can be adjusted to be movable in the axial direction with respect to the axles 6 and 5', and the distance τ1 of the protrusions 1a can be easily adapted to roofs using folded metal plates. be.

Reference numeral 7 denotes a wheel 3ON6 drive device mounted on a trolley 2, consisting of a worm reducer with an electric motor and other rotary transmissions, a chain wheel 8 wedged on its output shaft, and a chain wheel wedged on one axle 6. 9, and by forcibly rotating the wheels 3 and 3' on both sides of the transmission chain 10 through the axle 6, the trolley 2 becomes a rail as described above with the two protrusions 1afC.
It is designed to run as J'i.

Reference numeral 11 denotes a spray paint machine mounted on a trolley 2, which is an air-renu type using a diaphragm pump, which sucks paint directly from a paint can 12 through a suction hose 13, compresses and pressurizes it, and sends it through an on-off valve 14. Two paint hoses 15.1
5 and jets it out from an injection nozzle 16.16 attached to the tip of the hose 15.15. As shown in FIG. 2, the injection nozzle 16 includes a swinging arm 1 whose intermediate portion is swingably supported on the front surface of the truck 2 around a support shaft 18.
It is attached to the bottom end of 7. The upper end of each swing arm 17 is pivotally connected to a crank arm 21 fixed to an output shaft 20 of a rotary transmission 19 via a link 22, and when the crank arm 21 rotates, it moves by 1 [I8] and swings both ways. The arm 17.17 and the injection nozzle 16.16 are structured to swing from side to side. In the figure, reference numeral 23 denotes an electric motor that serves as a drive source for the rotational transmission device 19.

Reference numeral 24 denotes wheels for lateral movement that are installed close to the wheels 3 on both the front and rear sides of the truck 2, as shown in FIGS. 8 and 4.
The support frame 26 is connected to the operating shaft 27 of the toggle clamp 26, and is attached so that it can be raised and lowered by the operation lever 28, and is normally in the raised position shown in FIG. The structure is such that it does not get in the way of driving. When the first cart 2 moves to the end of the roof 1 along the protrusion 1a that becomes the rail, the lateral movement wheels 24
A guide rail/I/29 is arranged below the projection 1a so as to be substantially perpendicular to the protrusion 1a, and as shown in FIG. is pushed down and placed on the guide saw L/29, and floated together with the truck 2 with three traveling wheels, and then moved to the guide saw L/29 using the wheels 24 to move the truck 2. Let me.

It is laterally moved to a position above the protrusion 1a, which will become the next rail.

According to the present invention having the above-described configuration, the protrusion 1a of the roof 1 is used as a rail of the truck 2, and while the protrusion 1a is used to move the truck 2, the injection nozzle 16 that swings Spray the paint and paint the protrusion 1a of the roof 1 and the walls 1 on both sides of it.
The entire surfaces of the grooves 1b and 1b can be coated automatically and uniformly.

Moreover, Painting Sakushiba is excellent in terms of labor saving as it requires one worker to operate the trolley 2 and the painting station *11.
The practical effect of significantly reducing the overall paint trade is extremely large.

Note that the trolley 2 can also be structured so that a worker can ride on it.
