CAN INNER SURFACE-COATING APPARATUS

Provided is a can inner surface-coating apparatus with which inspection of bottomed cylinders can be favorably performed in parallel without being affected by the coating process. In the can inner surface-coating apparatus (1), inspection cameras (13a - 13c) to be used for inspection following coating of the inner surface of a bottomed cylinder that will become the body of a can or bottle-shaped can are disposed above spray devices (11a - 11c) that are used for coating the inner surface of bottomed cylinders. Moreover, the coating area (2a) including the spray devices (11a - 11c) and the inspection area (2b) including the inspection cameras (13a - 13c) are covered with a cover (20). By supplying air inside the cover (20) from the upper part (air supply port [202]) of the inspection area (2b) and discharging the air out of the cover (20) from the lower part (coating mist collection duct [22]) of the coating area (2a), an air flow is formed from the upper part of the inspection area (2b) to the lower part of the coating area (2a).
