AUTOMATIC MOVABLE DUST REMOVING DEVICE

摘要

PROBLEM TO BE SOLVED: To efficiently remove welding dust without interrupting a welding work. SOLUTION: A dust removing device 1 has a function of automatically adjusting the position of a hood 11 as a welding work is advanced. A means to move the hood 11 comprises a frame vehicle 12 to support the hood 11 and a driving vehicle 13 having an electric motor to push the frame vehicle 12 during the movement. Two optical sensors 132 and 132 to detect arc beams emitted during the welding are installed on the driving vehicle 13 in a longitudinally deviating manner in the advancing direction. The optical sensors 132 and 132 and the electric motor of the driving vehicle 13 are connected to each other via a relay circuit. COPYRIGHT: (C)2004,JPO&NCIPI
