PURPOSE:To facilitate restart in the event of an overrun of the table of automatic screw driving machine by stopping the drive motive when the sensor informs that any overrun has happened and by pushing back the table using an elastic member. CONSTITUTION:If the Z table 8 overrun during screw driving work, this table 8 is stopped by a stopper 20. At the same time, the overrun sensing switch 22 is actuated to shut off power to the motor 15. The Z table 8 is then pushed back by the elastic force of a compression spring 23, and the overrun sensing switch 22 is also turned off. In order to restart the Z table 8, just the restart switch shall be pushed, that means elimination of conventional works in which the Z table 8 is moved manually and the sensing switch 22 is turned off. |
