Abstract

A manufacturing device is configured to manufacture a molded product provided with a gas barrier layer, in which the gas barrier layer is formed on a surface of the molded product. The manufacturing device includes: a coater configured to coat the molded product with the gas barrier material; a drier configured to dry the gas barrier material applied by the coater; a surface modifier configured to modify a surface of the gas barrier material dried by the drier; and a transfer unit configured to transfer the molded product to the coater, the drier, and the surface modifier. The coater, the drier, and the surface modifier are consecutively connected and separated from each other by partitions.

First claim

1 . A manufacturing device of a molded product provided with a gas barrier layer, wherein the gas barrier layer is formed on a surface of the molded product, the manufacturing device comprising:
a coater configured to coat the molded product with a gas barrier material; a drier configured to dry the gas barrier material applied by the coater; a surface modifier configured to modify a surface of the gas barrier material dried in the drier, and a transfer unit configured to transfer the molded product to the coater, the drier, and the surface modifier, wherein the coater, the drier, and the surface modifier are consecutively connected, and the coater, the drier, and the surface modifier are separated from each other by partitions.

2 . The manufacturing device according to claim 1 , further comprising:
a measuring unit configured to measure at least one of the gas barrier material applied by the coater, the gas barrier material dried by the drier, and the gas barrier material modified by the surface modifier.

3 . The manufacturing device according to claim 2 , wherein
the measuring unit is consecutively connected to the coater, the drier, and the surface modifier, and the coater, the drier, the surface modifier, and the measuring unit are separated from each other by the partitions.

4 . The manufacturing device according to claim 3 , wherein
the molded product is transferred to the coater, the drier, and the measuring unit in this order.

5 . The manufacturing device according to claim 2 , wherein
the measuring unit is disposed inside at least one of the coater, the drier, and the surface modifier.

6 . The manufacturing device according to claim 1 , wherein
the drier is disposed at a center of the manufacturing device, a transfer opening of the coater and a transfer opening of the surface modifier are positioned facing the drier, and the transfer unit is disposed in the drier.

7 . The manufacturing device according to claim 1 , wherein
a transfer opening of the coater, a transfer opening of the drier, and a transfer opening of the surface modifier face a space in which the transfer unit is disposed.

8 . The manufacturing device according to claim 1 , wherein
the molded product is an elongated base material in a form of a roll, the transfer unit comprises: a feeding roller configured to feed the elongated base material; and a winding roller configured to wind the elongated base material, the coater comprises: a support roller supporting the elongated base material; and a die coater that is disposed opposite to the support roller across the elongated base material and is configured to coat the elongated base material with the gas barrier material, and the drier comprises: a plurality of transfer rollers configured to transfer the elongated base material; and a heater disposed opposite to the plurality of transfer rollers across the elongated base material.

9 . The manufacturing device according to claim 8 , wherein
the surface modifier comprises: an electrode roller configured to be wound with the elongated base material; a voltage applying unit configured to apply a voltage onto the electrode roller; and an electrode disposed opposite to the electrode roller across the elongated base material.

10 . The manufacturing device according to claim 8 , further comprising:
a measuring unit configured to measure at least one of the gas barrier material applied by the coater, the gas barrier material dried by the drier, and the gas barrier material modified by the surface modifier.

11 . The manufacturing device according to claim 10 , wherein
the measuring unit is disposed between the drier and the surface modifier.

12 . The manufacturing device according to claim 2 , wherein
the measuring unit measures at least one selected from the group consisting of a refractive index, light transmissivity, light reflectivity, chromaticity, film composition, film density, film defects and film thickness of the gas barrier layer.

13 . The manufacturing device according to claim 10 , wherein
the measuring unit measures at least one selected from the group consisting of a refractive index, light transmissivity, light reflectivity, chromaticity, film composition, film density, film defects and film thickness of the gas barrier layer.
