Abstract

PURPOSE:To obtain a color sheet which solves the parting of color sets with margin spaces and permits the exact judgement as to whether the color sets are O.K. or not by coating the front surface of the sheet with plural coating material coating film bands of adjacent different colors in the state of not having margin spacings and color laps adjacently to each other. CONSTITUTION:The long-sized sheet 3 which is continuously supplied by successively passing between respectively plural guide rollers 1 and tension rollers 1 is bypassed to supporting rolls 6 for coating supported on a supporting base 5 of a device frame 4 and the bypassing part is coated by a coating head 7. Namely, the coating materials different in colors stored in coating material tanks 16 are continuously supplied through tubes 17 and the coating material passages and divergent passages of the coating head 7 onto the front surface of the sheet 3. The adjacent coating film bands 26 of the different colors free from the margin spacings are formed at a parallel width L on the front surface of the sheet 3. Then, the color sets are not parted in the margin spaces when the sheet 3 is used as color samples of the color sets and, therefore, whether the color sets are okay or not is correctly judged.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a color sheet used as a color sample for paints such as signboards, vehicle markings, and wall materials for architects.

[0002]

2. Description of the Related Art Conventionally, there is a color sheet by printing, but since the color material of the paint is not a paint as a color sample of the paint, there is a large difference in color combination, color tone, and color sense from the actual product, which is not preferable for use. Therefore, a color sheet coated with a paint is used in order to eliminate the difference from the actual paint. In this color sheet, a plurality of paint film bands of different colors are applied to one sheet, but a blank space is formed between the paint film bands.

Therefore, when used as a color sample of a single color, there is no problem in such coating, but when used as a color sample of a color group such as two-tone color or multi-tone color, the above-mentioned margin is used. Since the space divides the color set, it hinders the determination of the color tone and the color, and there is a difference in the color tone and the color appearance from the actual product, and there is a problem that it is not possible to accurately determine whether or not the color set is possible.

[0004]

SUMMARY OF THE INVENTION Even when used as a color sample for a color set of not only a single color but also a multi-tone color, the present invention has no difference in color tone and color judgment of a paint from an actual product, and accurately The purpose is to provide a color sheet that can judge a set.

[0005]

The present invention relates to a seat,
It is characterized in that it is a color sheet coated with a plurality of paint coating bands in which different colors are adjacent to each other with no blank space and no color wrap.

[0006]

According to the present invention, since there is a blank space and a color wrap between adjacent paint coating strips, there is no intervening color between the color groups of the paint coating strips of different colors. Of course, when used as a color sample of a color set such as a two-tone color or a multi-tone color, it is possible to accurately judge the color tone and color of the color set without dividing the color set in the above-mentioned blank space, Since there is no difference in color tone and color sense, it is possible to accurately determine whether or not a color group is available.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings. The drawing shows a sheet coating apparatus for coating color sheets. In FIG. 1, a large number of guide rollers 1 ...
And a long sheet 3 that is continuously supplied through the tension rollers 2 ... To a supporting roll 6 for coating which is rotatably supported by supporting bases 5 fixed upright at both ends of the apparatus frame 4.
The coating head 7 is used for coating on the peripheral surface of the bypass portion. Here, the above-mentioned sheet 3
For example, a vinyl chloride sheet is used, and as the paint, a urethane resin-based paint is used.

The above-mentioned coating head 7 is horizontally adjustably attached to the dovetail groove 9 of the fixing substrate 8.
In addition, a swing base plate 12 that can swing about a swing fulcrum 11 by a lever handle 10 is provided.
By attaching the above-mentioned fixing substrate 8 to the above, the above-mentioned coating head 7 can be brought into contact with and separated from the sheet 3.

Furthermore, the above-mentioned swing substrate 12 is provided on the support base 5.
It is attached to a slider 13 supported so as to be able to move up and down, and is configured to lift and lower the slider 13 by rotating a worm wheel 15 with a worm 14 to finely adjust the distance between the sheet 3 and the coating head 7. is doing.

Furthermore, the worm wheel 15 described above.
A plurality of paint tanks 16 ... Are disposed above the above, and these paint tanks 16 ... Are connected to the above-mentioned predetermined portions of the coating head 7 by respective tubes 17 ...

The above-mentioned coating head 7 is constructed as shown in FIGS. That is, this coating head 7
The lower surface of the head block 18 as a roll-opposing surface is formed into an arcuate concave curved surface 19 along the roll curvature of the support roll 6 over the entire width direction of the sheet 3, and a plurality of, for example, a plurality of pieces are formed in the vertical direction of the head block 18 described above. Seven paint passages 20 are formed separately.

The concave curved surface 19 has one end (see FIG. 2).
The left end) of the sheet 3 communicates with the paint passage 20 and the other end (the right end of FIG. 2) of the sheet 3 in the conveying direction is widened to form a plurality of divergent divergent recesses 21 ... Two
The depths of 1 ... are set to be deeper on the side of the paint passage 20 and shallower in the direction of conveyance of the sheet 3.

That is, one end of the above-mentioned divergent recess 21 is set to have the same width as the diameter of the paint passage 20, and the cross-sectional shape of the one end and the other end are substantially the same. The depth is set.

A connection body 22 is screwed onto the upper end of the paint passage 20 in the head block 18, and this connection body 22 is connected.
An open / close valve 23 provided on the tube is configured to control the paint supply flow rate, and a tube 17 is provided between the connection port 24 of the connector 22 and the paint tank 16 (see FIG. 1).
