Abstract
The present invention provides a robot system including a robot having a plurality of move axes and a safeguard apparatus provided independently of a control system of the robot and adapted for limiting a movable range of the robot. The safeguard apparatus includes at least two individual-axis-detection external sensors configured to be respectively turned ON/OFF in response to a rotational position or a transfer position of respective at least two move axes among the plurality of move axes of the robot, and an apparatus body configured to limit a move of the robot based on a combination of ON/OFF conditions of at least two output signals obtained from the at least two individual-axis-detection external sensors.

A robot system including a robot having a plurality of move axes and a safeguard apparatus provided independently of a control system of the robot and adapted for limiting a movable range of the robot, wherein the safeguard apparatus includes at least two individual-axis-detection external sensors configured to be respectively turned ON/OFF in response to a rotational position or a transfer position of respective at least two move axes among the plurality of move axes of the robot, and an apparatus body configured to limit a move of the robot based on a combination of ON/OFF conditions of at least two output signals obtained from the at least two individual-axis-detection external sensors.
A robot system including a robot having a plurality of move axes and a safeguard apparatus provided independently of a control system of the robot and adapted for limiting a movable range of the robot, wherein the safeguard apparatus includes a composite-move-detection external sensor configured to detect a predetermined movable position of the robot provided by composite moves of at least two move axes among the plurality of move axes of the robot, and an apparatus body configured to limit a move of the robot based on an output signal obtained from the composite-move-detection external sensor.
