Sealant flow control method in sealing by an industrial robot
 A sealing gun (31) of a sealant application unit, which controls the flow of the sealant in accordance with the value of an input signal, is attached to the end of a robot arm. The value of a signal applied to the sealant application unit (30) is controlled in association with acceleration/deceleration control of the moving speed of the sealing gun. The moving speed (TSA) of the sealing gun and the flow (SC) of the sealant discharged from the sealing gun are in direct proportion; therefore, the bead width becomes uniform independently of the moving speed (TSA) of the sealing gun.
