CONSTITUTION:The main unit of a screw tightening machine, consisting of a robot R, provides an electric motor driven driver D in an end wrist (d) of the second arm (c) in the main unit. A hopper H', storing a screw, is fixed to a bracket 3 protruding from a turning root part a'. The wrist (d) fixes an auxiliary chute 4 for conveying a screw to a screw supply part 9g) of the electric motor driven driver D. While the hopper H' connects with a hopper side chute 5 which connects with the auxiliary chute 4 and delivers to it a screw when the robot 4 comes to a screw supply position. A fixed quantity supply unit is provided in a connection part between the hopper side chute 5 and the auxiliary chute 4. |
