Rotary atomizing head type coating device

A rotary atomizing head type coating system, comprising:

• a housing including a coating machine mount portion formed on a front side thereof for attaching a coating machine, and a feeder unit mount portion formed on a rear side for accommodating a feeder unit therein;
• a coating machine operatively be mounted on said coating machine mount portion of said housing, and having an air motor with a rotational shaft and a rotary atomizing head mounted on a fore end portion of said rotational shaft;
• a feed tube passage hole formed axially and internally of said rotational shaft of said air motor, and having a fore end opened toward said rotary atomizing head and a rear end opened into said feeder unit mount portion of said housing;
• a plural number of feeder units providing supply sources for a variety of paint colors and being adapted to be replaceably and selectively loaded into said feeder unit mount portion of said housing, each one of said feeder unit including a valve receptacle portion accommodating a paint valve and a solvent valve therein, and a feed tube extending axially forward from said valve receptacle portion to supply paint or solvent toward said rotary atomizing head from said paint valve or solvent valve, said feed tube of said feeder unit being placed in said feed tube passage hole when loaded into said feeder tube mount portion;
• paint conduits connected between said feeder units and paint sources of different colors to supply a variety of paint colors separately to the respective paint valves of said feeder units;
• and
