Circuit for supplying/interrupting power to robots

A circuit for supplying/interrupting power to robots according to claim 10, wherein said circuit for supplying/interrupting power to robots further comprises:

• relay contacts installed between a power source and servo amplifiers, each relay contact installed between the power source and a corresponding servo amplifier for a corresponding robot of the robots;
• relays, each relay corresponding to a respective relay contact of said relay contacts;
• and
• cutoff switch circuits for energizing or deenergizing said relays, each cutoff switch circuit corresponding to a respective relay, and each cutoff switch interrupting the power supplies to a respective servo amplifier for each axis of the corresponding robot when operated, causing the power supplies to said respective relay and said respective relay contact to be turned off.

A circuit for supplying/interrupting power to robots in a robot control system for controlling robots using one controller, comprising:

• power supply means for supplying power to said robots;
• a common power interrupting circuit coupled between said robots and said power supply means, which simultaneously interrupts power being supplied to said robots, said common power interrupting circuit comprising:
• relay contacts, coupled between the power supply means and servo amplifiers, each relay contact of the relay contacts coupled between the power supply means and a respective servo amplifier, each servo amplifier coupled to a respective robot of said robots, and
• relays, each relay corresponding to a respective relay contact of said relay contacts and each relay coupled to a respective emergency stop signal generating means associated with a respective robot, so that the power supplied to the robots is simultaneously interrupted by operating any of said respective emergency stop signal generating means and the respective relay contact is turned off.

A circuit for supplying/interrupting power to robots in a robot control system for controlling robots by one controller, comprising:

• a common power interrupting circuit, which simultaneously interrupts power supplies to robots, said common power interrupting circuit comprising:
• a plurality of relay contacts, each relay contact coupled in series between a power source and a servo amplifier of a corresponding robot of said robots;
• and
• relays, which correspond to a respective relay contact of the plurality of relay contacts, each said relay connected to at least two of a corresponding emergency stop command signal generating means of a peripheral device associated with the corresponding robot, a first emergency stop command switch installed in a teaching panel, and a second emergency stop command switch installed on a manual operating panel of the one controller, such that power supplied to each of the robots is simultaneously interrupted by operating one of said emergency stop command signal generating means and either of said first or second emergency stop command switches corresponding to any robot of said robots, causing one relay contact of the corresponding relay contacts to be turned off.

A circuit for supplying/interrupting power to robots in a robot control system for controlling robots by one controller, comprising:

• a common power interrupting circuit which simultaneously interrupts power supplies to the robots, and
• power interrupting circuits, each power interrupting circuit corresponding to an individual robot of the robots, each power interrupting circuit individually interrupting the power supplies to the corresponding individual robot,
• said common power interrupting circuit comprising:
• one or more common circuit relay contacts, connected, in series, and coupled to one side of a power source;
• common circuit relays, each common circuit relay corresponding to a respective first relay contact of said common circuit relay contacts, said common circuit relays being connected to at least one emergency stop command switch of a first group, and
• each said power interrupting circuit comprising:
• series-connected relay contacts, each series-connected relay contact coupled between a respective relay contact of said common power interrupting circuit and a servo amplifier corresponding to a respective robot;
• and
• relays, which correspond to said series-connected relay contacts and are connected to at least one emergency stop command switch of a second group, said second group being different from said first group of the emergency stop command switch,
• the power supplies to the robots being simultaneously interrupted or the power supplies to only one robot of the robots being interrupted or the power supplies to only one robot of the robots being interrupted depending on whether the at least one emergency stop command switch is of the first group or the second group, when one of said emergency stop command switches is activated, to cause a respective common circuit relay contact in said common power interrupting circuit to interrupt the power supplies to all of the robots or the respective relay contact in said power interrupting circuit for interrupting the power supplies to the respective robot.
