Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention
Paint in relatively small units
Paint of the desired paint color can be automatically supplied to the coating machine.
The present invention relates to an apparatus for supplying various kinds of small amount paint. 2. Description of the Related Art Conventionally, a variety of paint colors has been
In order to improve the workability of multicolor coating, various ideas and
Means have been proposed. For example, the Applicant
Japanese Patent Publication No. 3-40389, Japanese Utility Model 4-9013, Japanese Utility Model 4
-46846, Jitsuhei 4-46847, etc.
Like, a few turntables centered on an upright spindle
Rotatable and spaced apart above and below, with a variety of paints
Place a color paint tank on the turntable, and
The rotation of the turntable causes the required paint color
To carry it to the worker side.
Disclosure of various types of paint supply devices
And many of them have already been commercialized. These many
A small amount of paint supply equipment is mainly used for hand-painted paint.
That are designed to make the change of the product smooth and easy
It is. Therefore, the above-mentioned various kinds of small amount paint supply apparatus is
If a relatively small amount of paint is used at the wet simple painting booth
When painting relatively small products individually
It was a suitable device. On the other hand, painting of automobile bodies etc.
Smell in a large painting booth (tunnel booth)
Painting robot and / or automatic painting equipment (top,
Side), etc., the same
It is said that automatic painting sometimes advances with frequent color change operations
The method is performed by the following method. And in recent years, heels
Demand for multi-color coating has increased especially for automatic coating,
Already several to dozens of colors of paint for painting robots etc.
Several multicolors designed to be available
A coating system has been proposed (Japanese Patent Publication No. 7-34882)
Report, JP-A-4-83549). But so far
The proposed multi-color coating system is, for example, a pipe for each paint color
From each supply from the paint tank or paint system
Relatively large per color by a method such as guiding
With a configuration that continuously supplies a quantity of paint to a painting robot, etc.
there were. [0003] By the way, an automobile body
Recently became a car buyer at a paint factory
Each car box is painted with the paint of the respective paint color desired by each individual.
It is required to be able to paint individual di
You. Due to this situation, it can be used for painting automotive bodies
Paint colors range from dozens to more
In addition, multi-color painting has progressed further, and on the other hand, white paint
Except for paints used in large quantities such as
The amount is getting smaller. Therefore, just like
Use a painting robot to paint many colors in smaller units.
Equipment that can be selectively supplied to
Development is required. But developed so far
Conventional multi-color coating systems can meet this demand well.
It was something that could not be done. Therefore, the applicant has
Of the conventional turntable type multi-quantity small quantity paint supply device
Some good pump tanks with different paint colors
New turntable type multi-quantity small quantity paint supply equipment equipped with
And apply it to the earlier patent application (Japanese Patent Application No. 9-281472).
No.). However, the disclosed various small paints
Since the supply device has several pumping tanks,

By appropriately refilling the paint cartridges 1
In other words, replace with a paint cartridge 1 of a required paint color as needed.
This makes it possible to perform multi-color automatic painting using many paint color types.
It becomes possible. For example, if a car buyer
Each paint selected from dozens of paint colors
Each work (car body) is individually
It is also possible to paint. Moreover, with this device
Means five paint cartridges 1 ・
・ The rotation of the paint cartridge 1
Paint can be efficiently agitated and paint sedimentation can be effectively performed.
Can be suppressed. Therefore, this device uses a painting robot etc.
With continuous frequent color change operations
For use in automatic painting of advancing auto bodies, for example,
Very suitable. As described above, the various small amounts of the present invention
According to the paint supply device, paints of various paint colors are specified respectively.
Prepare in the unit of quantity, and for the required paint color
Paint can be selectively supplied to painting machines, etc., and
The paint color can be changed quickly, and moreover,
The effect that the body is smaller and sufficient is obtained. And
The present invention is directed to these disclosed various low volume paint supply devices.
However, painting is continuously performed in a flow operation using a painting robot etc.
In particular, car bodies, etc., that progress with frequent color changing operations
It also has the advantage that it is suitable for automatic painting.

Claims (1)

Claims 1. An apparatus capable of preparing a plurality of paints having different paint colors in units of small-capacity paint cartridges and supplying a paint of a paint color selected from them. A substantially cylindrical cartridge which has a paint outlet at one end of the cartridge and an air inlet at the other end, and is filled with paint so that the paint cartridge and the paint cartridge can be placed. A base body having a plurality of seats arranged substantially horizontally in parallel, each of the plurality of seats supporting a placed paint cartridge rotatably about its longitudinal axis; and a paint cartridge. A mechanism for simultaneously agitating each of the paints therein, provided in cooperation with a plurality of the seating portions, respectively, and rotating the placed paint cartridges together. An agitation mechanism that can be used as a means for supplying paint, a paint connector connected to a coating machine or the like via paint piping, and an air connector connected to the pressurized air source via air piping, The seating portions are provided so as to be opposed to each other, and when these two connectors are located at positions facing the placed paint cartridge, the paint connector is moved to be connected to the paint outlet, and at the same time, the air is removed. A paint supply means for displacing paint from the paint cartridge to the paint connector by injecting pressurized air following these connections, comprising a cylinder device for moving a connector to be connected to the air inlet; A mechanism for selecting a color, wherein the moving base on which the paint supply means is assembled is reciprocally movable over the entire width of the seating portions arranged in parallel. For example, and, the paint connector and air connector, comprising a movement control mechanism that can be transported to the paint cartridge and a position opposed to the specified paint color, wide minor paint supply device.
