Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coating tank.

[0002]

2. Description of the Related Art In a pressurized tank generally used for painting, a paint is directly charged into a pressurized tank, and the paint is supplied to a paint gun by pressurizing the inside of the pressurized tank with a gas.

As an example of such a device, Japanese Patent Application Laid-Open No. Hei 9-193994 has been known.

[0004]

However, in such a conventional coating tank, it is necessary to transfer the paint from the can to the pressurized tank at the time of use, so that the transfer causes a loss of the paint. There is.

In addition, when changing colors to another color, the pressurized tank must be sufficiently washed. If cleaning is insufficient, color mixing occurs in the pressurized tank, resulting in poor coating. There is a risk of becoming. In addition, paint loss occurs due to cleaning.

Accordingly, an object of the present invention is to solve the above-mentioned problems, to reduce the loss of paint, and to provide a paint tank capable of easily changing colors.

[0007]

According to a first aspect of the present invention, there is provided a pressurized tank capable of storing a paint can, and the pressurized tank can be pressurized inside. A pressurizing means is provided, and a suction nozzle capable of sucking paint in the paint can to the outside is provided.

According to the first aspect of the present invention, the paint can is housed in the pressurized tank and the paint is sucked from the paint can. It is only necessary to change the paint can, so that there is no need to transfer the paint from the paint can to the pressurized tank, and it is possible to eliminate paint loss due to the transfer.

[0009] When the color can be changed to another color, the paint can can be replaced with another color can, so that the pressurized tank is not required to be cleaned and paint loss due to the cleaning is eliminated. be able to.

Further, since a single pressurized tank can support a plurality of colors, the structure is simplified and the installation space is reduced as compared with a system having a dedicated system for each color. Become like

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, specific embodiments of the present invention will be described with reference to the drawings.

1 to 3 show an embodiment of the present invention.

In this embodiment, a pressurized tank 2 capable of storing a paint can 1 is provided. The pressurized tank 2 is a sealed container including a container body 3 having an open upper end, and a closed lid 5 that can be attached to and detached from an opening 4 of the container body 3. A lock mechanism 6 is provided between the container body 3 and the lid 5 as necessary.

A small hole (not shown) is formed in the cover 5, and one end of a pressurizing means such as a pressurizing nozzle 7 for pressurizing the inside of the pressurizing tank 2 with a gas such as air in the small hole. Attach the parts from outside in a sealed state. A regulator 8 is attached to the pressurizing nozzle 7 at an intermediate part, and an air supply source (not shown) such as a compressor is connected to the other end via an air hose (not shown). Note that one end of the pressurizing nozzle 7 may penetrate the lid 5.

Further, one end of a suction nozzle 9 capable of sucking out the paint in the paint can 1 to the outside is penetratingly arranged in the lid 5 of the pressurized tank 2 in a sealed state. A paint gun or the like is attached to the other end of the suction nozzle 9 located outside the pressurized tank 2 via a suction hose (not shown). At this time, positioning means for the paint can 1 is provided in the pressurized tank 2, and the suction nozzle 9 is mounted at a position on the lid 5 corresponding to the opening of the paint can 1 housed and positioned in the pressurized tank 2. To do.

Next, the operation of this embodiment will be described.

As shown in FIG. 3, a paint can 1 is accommodated in a pressurized tank 2. Then, the lid of the paint can 1 is opened, and the lid 5 is attached to the pressurized tank 2 so that the suction nozzle 9 is inserted into the paint can 1 as shown in FIG.
State. At this time, positioning means for the paint can 1 is provided in the pressurized tank 2, and the suction nozzle 9 is attached to a position on the lid 5 corresponding to the opening of the paint can 1 housed and positioned in the pressurized tank 2. By doing so, installation of the paint can 1 in the pressurized tank 2 and insertion of the suction nozzle 9 into the paint can 1 can be facilitated.

In this state, air is supplied from a not-shown air supply source such as a compressor into the pressurized tank 2 through an air hose, a regulator 8 and a pressurizing nozzle 7 to pressurize the pressurized tank 2. The paint is supplied to the paint gun through the suction nozzle 9 to perform painting.

As described above, since the paint can 1 is accommodated in the pressurized tank 2 and the paint is sucked out of the paint can 1, the paint can 1 runs out in the reverse procedure when the paint in the paint can 1 runs out. It is only necessary to replace the paint can 1, so that the trouble of transferring the paint from the paint can 1 to the pressurized tank 2 is eliminated, and the loss of paint due to the transfer can be eliminated.

When the color can be changed to another color, the paint can 1 can be replaced with another color. Therefore, the cleaning of the pressurized tank 2 becomes unnecessary and the loss of the paint due to the cleaning is eliminated. Can be eliminated.

Further, since a single pressurized tank 2 can handle a plurality of colors, the structure is simplified and the installation space is reduced as compared with a system having a dedicated system for each color. Will be done.

[0022]

As described above, according to the first aspect of the present invention, since the paint can is housed in the pressurized tank and the paint is sucked out of the paint can, the paint in the paint can has run out. In this case, it is only necessary to replace the paint can, so that there is no need to transfer the paint from the paint can to the pressurized tank, and it is possible to eliminate paint loss due to the transfer.

When the color can be changed to another color, the paint can can be replaced with another color can, so that cleaning of the pressurized tank becomes unnecessary and paint loss due to cleaning is eliminated. be able to.

Further, since a single pressurized tank can support a plurality of colors, the structure is simplified and the installation space is reduced as compared with a system having a dedicated system for each color. And a practically useful effect.
