Robot coating system

A robot coating system which includes a robot which is provided with a coating gun which uses a pump to coat a viscous material and in which said coating gun coats a plurality of planned coating positions of a workpiece with said viscous material in exactly predetermined amounts to thereby scatter coat the viscous material, the robot coating system comprising:

• a robot moving unit configured to make said robot which is provided with said coating gun successively move to said plurality of planned coating positions at the time of operation of said robot coating system,
• a pilot pressure imparting unit configured to make said pump of the coating gun before reaching said planned coating positions and imparts to said viscous material a predetermined pilot pressure without coating said viscous material,
• a coating executing unit configured to execute coating work of said viscous material by a predetermined flow rate over a predetermined coating time when said coating gun has reached a planned coating position or immediately before that,
• a post-coating stopping unit configured to continue said coating work by said coating executing unit and make said pump stop after the end of said coating work when said coating executing unit is executing said coating work and a first command is issued to stop said robot,
• an immediate stopping unit configured to make said pump stop without continuing said coating work by said coating executing unit when said coating executing unit is executing said coating work and a second command is issued to stop said robot, and
• a selection unit configured to execute one of said post-coating stopping unit and said immediate stopping unit for functioning.
