Coating device

A coating device which coats a container, comprising:

• a conveyor which conveys the container;
• first and second annular belts which are arranged on two sides of said conveyor to sandwich the container on said conveyor and configured to rotate the container on the conveyor;
• an adjusting mechanism which adjusts a gap between opposing portions of said first and second annular belts in accordance with a size of the container to be coated;
• a first supply mechanism which supplies a coating liquid to at least one of said first and second annular belts;
• a second supply mechanism which supplies a cleaning liquid to said first and second annular belts;
• a first pan which receives a liquid dropping from said first annular belt and discharges the liquid through a first discharge port;
• a second pan which receives a liquid dropping from said second annular belt and discharges the liquid through a second discharge port;
• a first discharge channel which receives at first receiving ports the liquid discharged through said first and second discharge ports and discharges the liquid to a first discharge destination;
• a second discharge channel which receives at second receiving ports the liquid discharged through said first and second discharge ports and discharges the liquid to a second discharge destination;
• and
• a driving mechanism to arrange said first and second pans so as to position said first and second discharge ports above said first receiving ports in a coating mode of the container and so as to position said first and second discharge ports above said second receiving ports in a cleaning mode of said first and second annular belts,
• wherein said first annular belt is so arranged as to move together with said first pan, said second annular belt is so arranged as to move together with said second pan, and the gap between said first and second annular belts in the cleaning mode of said first and second belts is larger than that in the coating mode of the container by driving of said first and second pans by said driving mechanism.
