Abstract
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, inspection cameras 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 that are used for coating the inner surface of bottomed cylinders. Moreover, the coating area including the spray devices and the inspection area including the inspection cameras are covered with a cover. By supplying air inside the cover from the upper part (air supply port) of the inspection area and discharging the air out of the cover from the lower part (coating mist collection duct) of the coating area, an air flow is formed from the upper part of the inspection area to the lower part of the coating area.
