Problems solved by technology

[0010] Under such circumstances, in Patent Document 1 and Patent Document 2, it is not sufficient to remove disturbing vibrations, and uneven coating may occur
Even if the distance between the coating head and the backup roll is fixed by fixing the back-up roll that supports the coating head and the strip to solve this problem, it is difficult to prevent uneven coating due to the influence of disturbing vibrations.

Embodiment Construction

[0033] Preferred embodiments of the coating device in the present invention will be described below with reference to the drawings.

[0034] [Production line of optical compensation sheet]

[0035] FIG. 1 is an explanatory diagram illustrating a production line of an optical compensation sheet to which a coating method and a coating apparatus in the present invention are applied.

[0036] As shown in FIG. 1 , the production line of the optical compensation sheet is configured such that a belt-shaped body 16 serving as a transparent support on which a polymer layer for forming an alignment film is formed in advance is output from an output machine 66 . The strip 16 is guided by guide rollers 68 and fed into a polishing treatment device 70 . The polishing roll 72 is provided for polishing the polymer layer. A dust remover 74 is provided downstream of the buffing treatment device 70 . Dust adhering to the surface of the strip 16 can be removed by a dust remover 74 .

Abstract

The invention provides a coating device which can acquire coating films with high thickness precision and smooth surface as well as in free of uneven coating. The coating device includes: a support roller (20) which uses an outer circumference to support a long ribbon body (16) moves longitudinally, a coating device (10) of a coating head (18) which is provided oppositely with certain gap from the support roller (20) and supplies the coating liquid to the ribbon body, wherein the coating device includes a bracket (30) fixed with the coating head (18 and the support roller (20), and an active vibration eliminating device (32); the active vibration eliminating device (32) includes an actuator (33) for supporting the bracket (30) and driving, a first sensor (34) for detection of the vibration of the bracket (30), a second sensor (35) for detection of fundamental vibration, a third sensor (36) for detection of the vibration of the ribbon body, and a control mechanism which, on the basis of the information of each sensor, generates a control input for eliminating the vibration.

Description

technical field [0001] The present invention relates to a coating device, in particular to a coating device for coating a coating liquid on a continuously traveling strip (belt support) so as to form a coated film surface with a uniform thickness. Background technique [0002] In the fields of photographic photosensitive materials and magnetic recording media, the method of forming a coating film by applying a predetermined coating liquid to a continuously running belt-shaped flexible support (hereinafter referred to as "belt") is used. Coating process. In recent years, in these fields, a coating technique capable of obtaining a coating film with high thickness accuracy and a smooth surface free from coating unevenness has been demanded. [0003] Likewise, the coating technique described above is also required in the coating process applied to the production of optical films having various functions, such as optical compensation films, antireflection films, and antiglare f...
