## Abstract

A robot coating system (1) includes a robot moving unit (21) which makes a robot (11) having a coating gun (12) successively move to a plurality of planned coating positions, a readying pressure imparting unit (22) which drives a pump (13) of the coating gun before reaching the planned coating positions and imparts to the viscous material a predetermined readying pressure without coating the viscous material, a coating executing unit (23) which executes coating work of the viscous material by a predetermined flow rate over a predetermined coating time when the coating gun has reached a planned coating position, and a post-coating stopping unit (24) which continues the coating work to make the pump stop after the end of the work when executing the coating work and a stop command of the robot is issued.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

The robot coating system as set forth in claim 1, further comprising a robot retracting unit configured to make said robot retract to at least said coating start position when a stop command of said robot is issued and said robot stops over the coating start position of said planned coating position before coating said viscous material at one planned coating position among said plurality of planned coating positions.

### Claim 3 (depends on 1)

The robot coating system as set forth in claim 1, further comprising
an input unit which teaches coating conditions of said coating work and
a display unit which displays at least one coating condition which is taught from said input unit including a coating time and flowrate of said viscous material and at least one planned coating position.

### Claim 4 (depends on 2)

The robot coating system as set forth in claim 2, further comprising
an input unit which teaches coating conditions of said coating work and
a display unit which displays at least one coating condition which is taught from said input unit including a coating time and flow rate of said viscous material and at least one planned coating position.
