Painting method and painting facility

A painting facility, comprising:

• a preceding painting area equipped with a preceding sprayer for effecting a preceding painting operation on a painting object by paint spraying;
• a preceding painting robot as a part of a painting robot having an arm leading end portion and while effecting the preceding painting operation on the painting object, displacing the painting object relative to the preceding sprayer by an action of the preceding painting robot, keeping the painting object connected to the arm leading end portion of the preceding painting robot;
• a subsequent painting area equipped with a subsequent sprayer for effecting a subsequent painting operation on the painting object by paint spraying;
• a subsequent painting robot as a part of the painting robot having an arm leading end portion and, which, while effecting the subsequent painting operation on the painting object, displaces the painting object relative to the subsequent sprayer by an action of the subsequent painting robot, while keeping the painting object connected to the arm leading end portion of the subsequent painting robot;
• a holder via which the painting object is connected to the arm leading end portion of each of the preceding painting robot and the subsequent painting robot;
• a transfer section located near the preceding painting area and the subsequent painting area;
• and
• a controller for causing the preceding painting robot and the subsequent painting robot respectively to act automatically in accordance with a preset operational program;
• wherein, after completion of the preceding painting operation in the preceding painting area, the controller causes the painting object connected to the arm leading end portion of the preceding painting robot via the holder to be held to the transfer section by an action of the preceding painting robot with the holder, and connection between the arm leading end portion of the preceding painting robot and the holder is released, while keeping connection between the painting object and the holder, and
• wherein subsequently, while the arm leading end portion of the preceding painting robot is retracted from the transfer section, by an action of the subsequent painting robot, the controller causes the arm leading end portion of the subsequent painting robot, while keeping the connection thereof to the painting object, to be connected to the holder, which is being held to the transfer section, such that the painting object is shifted to the subsequent painting operation in the subsequent painting area in succession.
