CIRCUIT FOR CUTTING POWER SUPPLY TO ROBOT.

摘要

A circuit for cutting power supply to two robots (1 and 2) controlled by one controller (10). The power supply cutting circuit comprises a common power source cutting circuit which cuts off the power supply to two robots simultaneously, and power supply cutting circuits each of which cuts off the power supply to the corresponding robot independently. When a common cutoff switch circuit (14) of the common power supply cutting circuit is actuated by an emergency stop signal or an alarm signal, two relays (7 and 8) are deenergized at the same time. The power to the two robots are suspended simultaneously. On the other hand, when one of the cut-off switch circuits (12 and 13) of the power supply breaking circuits is actuated by an emergency stop signal or an alarm signal, only one corresponding relay (7 or 8) is deenergized to cut off the power supply to the corresponding robot.
