BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roll coater apparatus using a strip as an object to be coated.

[0002]

2. Description of the Related Art Conventionally, as a coating technique using a roll, a method of combining one or a plurality of rolls is known. For example, in a single-roll system, the paint is supplied to a roll and is transferred from the roll surface to an object to be coated. In this method, a predetermined coating film thickness can be obtained by adjusting the paint viscosity, the roll rotation speed, and the like. Also, in the method of combining a plurality of rolls, by changing the paint viscosity, the rotation speed of the rolls, the gap between the rolls to be combined, the pressing pressure, etc., the paint film thickness on the roll surface is sequentially changed, and a predetermined paint film thickness is obtained. can get.

FIG. 4 shows a conventional roll coater apparatus. The roll coater device in FIG.
The lower surface of the roll 1 is immersed in the paint stored in the paint pan 2 and the roll is rotated to lift the paint on the roll 1 and transfer the paint to an object to be coated or another roll. Regarding the cleaning of the rolls of the roll coater device, a method in which the paint in the paint pan 2 is removed and replaced with a cleaning liquid, the lower surface of the roll 1 is immersed in the cleaning liquid, and the cleaning liquid is circulated on the roll surface by rotating the roll. Had been taken.

[0004]

Under this configuration, the paint remaining on the surface of the roll 1 after coating is washed by the cleaning liquid in the paint pan, but the paint remaining on the end face of the roll 1 is not Since the cleaning liquid cannot be sufficiently lifted only by the rotation of the roll 1, it is inevitable that the paint adhered to the end face of the roll is manually scraped off with a spatula and then wiped off.

Accordingly, the present invention makes it possible to reduce the amount of paint remaining on the roll end face after the completion of coating, eliminate the need for manual scraping and wiping of the remaining paint, and to clean the roll end face without manual work. It is an object of the present invention to provide a roll coater device.

[0006]

SUMMARY OF THE INVENTION The present invention advantageously solves the problems of the prior art. To achieve the above-mentioned object, the inventors have devoted their efforts to a manual operation. It is possible to efficiently clean the end face of a roll, and the gist of the invention is as follows. (1) In a roll coater device configured to transfer paint to an object to be coated via a roll, In addition to providing a cover of a material that is easy to repel paint on the roll shaft,
A roll coater device, wherein a collar structure is arranged on a roll shaft. (2) The roll coater according to (1), wherein a spray washer is provided on the end face of the roll. (3) The roll coater according to (1), wherein a conical cover, a grooved cover, or an uneven cover is used as the cover. It is in.

[0007]

The present invention will be described below in detail with reference to the drawings.
FIG. 1 is a schematic view of a roll coater device according to the present invention.
In FIG. 1, the lower surface of the roll 1 is immersed in a paint pool stored in a paint pan 2, and the paint is lifted on the roll 1 by rotating the roll, and the paint is transferred to an object to be coated or another roll to paint. It consists of a device to be performed.

With this configuration, conical covers 3a, 3b made of a material that is easy to repel paint, for example, a fluororesin, are provided on the end face of the roll 1, and collar structures 4a, 4b are provided outside the covers 3a, 3b. Is provided. In the roll cleaning operation, after the coating is completed, the paint is removed from the paint pan 2, the cleaning liquid is filled in the paint pan 2, and the lower surface of the roll is placed in the paint pan 2.
Immerse in the cleaning solution inside. Thereafter, the cleaning liquid is pumped up to the roll surface by the rotation of the roll, and the roll surface is cleaned. At the same time, the cleaning liquid supply valve 6 is opened, and the cleaning liquid is supplied to the roll end face by the spray cleaners 5a and 5b to clean the roll end face. At this time, the paint is repelled by the cover provided on the end face of the roll, and the paint remaining on the end face is effectively flowed off. The cleaning liquid overflows along the roll axis, but is prevented from overflowing by the brim structures 4a and 4b, and falls into the paint pan.

In FIG. 2, covers 3a 'and 3b' having a radial groove structure 7 made of a material which is easy to repel paint are provided on the end face of the roll 1 and have the same structure as that of FIG. 3a ', 3b', outer flange structure 4
a, 4b are provided. In the roll cleaning operation, after the coating is completed, the paint is removed from the paint pan 2 and the cleaning liquid is applied to the paint pan 2.
And the lower surface of the roll is immersed in the cleaning liquid in the paint pan 2. Thereafter, the cleaning liquid is pumped up to the roll surface by the rotation of the roll, and the roll surface is cleaned. At the same time, the cleaning liquid supply valve 6 is opened, and the spray cleaning devices 5a and 5b are opened.
Thus, the cleaning liquid is supplied to the roll end face, and the roll end face is also cleaned. At this time, the paint is repelled by the cover provided on the roll end face, and the cleaning liquid is agitated on the roll end face by the groove 7, so that the paint remaining on the end face is effectively flowed down. The washing liquid overflows along the roll axis, but is prevented from overflowing by the brim structures 4a and 4b, and falls into the paint pan.

FIG. 3 also has covers 3a "and 3b" having an uneven structure 8 made of a material which is easy to repel paint on the end face of the roll 1 based on the same structure as that of FIG.
A collar structure 4a, 4b is provided outside the cover 3a ", 3b".
Is provided. In the roll cleaning operation, after the coating is completed, the paint is removed from the paint pan 2, the cleaning liquid is filled in the paint pan 2, and the lower surface of the roll is immersed in the cleaning liquid in the paint pan 2. Thereafter, the cleaning liquid is pumped up to the roll surface by the rotation of the roll, and the roll surface is cleaned. At the same time, the cleaning liquid supply valve 6 is opened, and the cleaning liquid is supplied to the roll end face by the spray cleaners 5a and 5b to clean the roll end face. At this time, the coating liquid is repelled by the cover provided on the roll end face, and the cleaning liquid is stirred on the roll end face by the unevenness 8, so that the paint remaining on the end face is effectively flowed down. The washing liquid overflows along the roll axis, but is prevented from overflowing by the brim structures 4a and 4b, and falls into the paint pan.

[0011] The form of the end face cover is determined by the type of paint,
The diameter of the roll and the type of the cleaning liquid are comprehensively determined, and an appropriate one is selected from the above (1) conical type, (2) grooved type, and (3) uneven type . The paint remaining on the surface of the roll 1 as in the related art can be easily washed simultaneously with the washing of the roll surface without manual operation.

[0012]

As described above, in the roll coater device, by covering the roll end face and providing the spray cleaner, the roll end face can be cleaned simultaneously with the cleaning of the roll surface without manual operation. Can be performed efficiently.
