Mounted on a wrist portion ( ) of a single coating robot ( ) is a common main assembly body ( ) to which a plural number of bell-shape heads ( ) are replaceably connectible. Further, a head changer ( ) is provided within a working area of the coating robot ( ), the head changer ( ) being provided with head gripping mechanisms ( ) to hold a plural number of bell-shape heads ( ) thereon. By the use of the coating robot ( ), one of the bell-shape heads ( ) on the head changer ( ) is replaceably connected to the common main assembly body ( ) to form a complete sprayer ( ). Accordingly, the coating robot ( ) can perform various coating operations by selectively picking up a suitable bell-shape head ( ) from the head changer ( ) and connecting same to the common main assembly body ( ).

Automatic coating apparatus

A rotary atomizing head type coating system capable of multiple color changes in the course of a coating operation. A housing (,) with a coating machine (,) is mounted on a wrist portion (,) of a coating robot. Provided for the coating system are a plural number of feeder units (,) which serve as separate sources for a variety of paint colors and which each accommodate a paint valve (,) and a solvent valve (,). Through paint hoses (,) and solvent hoses (,), the respective feeder unit (,) are connected to paint supply lines (,) of different colors and a solvent supply line (,). In order to supply paint of different colors to the coating machine (,) during a coating operation, the feeder units (,) are selectively and replaceably loaded into the housing (,). The use of a plural number of feeder units (,) which can be replaceably attached to the coating machine (,) makes it possible for the coating system (,) to cope with multiple color changes whenever necessary in the course of a coating operation.

Rotary atomizing head type coating device

A coating system which is provided with a plural number of feeder units for different paint colors in such a way as to permit color changes within a shortened period of time. Unit waiting devices for different paint colors are located in the vicinity of a coating robot. The unit waiting devices each include a feeder unit loader adapted to load and unload one of feeder units into and out of a rotary atomizing head type coating machine, which is mounted on a fore end portion of the arm of the coating robot, and a hose gripper adapted to hand over or receive one of supply hoses to and from a hose gripper which is provided on the side of the arm. As a consequence, the paint color can be changed by replacing a paint feeder unit on the coating machine by a specified one of feeder units of different colors which are supported on the unit waiting devices.
