Coating system having plurality of coating robots and operation robot having five arms

A coating system comprising:

• a plurality of coating robots provided in a coating booth and configured to coat a vehicle conveyed in a conveyance direction;
• and
• an operation robot provided in the coating booth on an upstream side or a downstream side of the plurality of coating robots in the conveyance direction, the operation robot being configured to operate an open/close member provided at a front or a rear portion of the vehicle, the operation robot comprising:
• a first arm configured to turn around a first axis along a vertical direction;
• a second arm having a base end side supported at a tip side of the first arm, the second arm being configured to turn around a second axis parallel to the first axis;
• a third arm having a base end side supported at a tip side of the second arm, the third arm being configured to turn around a third axis parallel to the first axis, the third arm extending downward along the third axis;
• a fourth arm having a base end side supported at a tip side of the third arm, the fourth arm being configured to turn around a fourth axis perpendicular to the first axis;
• a fifth arm having a base end side supported at a tip side of the fourth arm, the fifth arm being configured to turn around a fifth axis parallel to the fourth axis;
• and
• a tip jig having a base end side attachably/detachably supported at the fifth arm, the tip jig being configured to turn around a sixth axis with respect to the fifth arm, the sixth axis being selectively parallel to the fifth axis or perpendicular to a plane which includes the fourth axis and the fifth axis.
