1.6.1. Safety Fence

 

Install safety fence against the possible collision between the robot and workers, so that no worker may approach the robot.

 

Install safety fence against the possible collision between the robot and workers, so that no worker may approach the robot. When operators or other personnel enter the robot's working envelope by accident, it may cause an accident. Install the safety fence to stop the robot when one, who intends to replace for TIP DRESSING or TIP changing replacement, or to inspect welding equipment, opens the fence gate and approaches the equipment during operation.

 

Figure 1.1 Recommended size for safety net and entrance gate (slot type entrance gate)

 

Figure 1.2 Recommended size for safety net and entrance gate (square type entrance gate)

(1)    Enough space for safety net should be secured by covering robot operating area so as that workers would not have difficulty in teaching work or repairing work, and the safety net should have solid structure in order that it would not move easily and man cannot enter over easily.

 

(2)    Safety net should be installed by static type in principle, and should not have hazardous parts such as prominence and depression or keen part, etc.

 

(3)    Install the safety fence with an entrance gate, and register the safety plug at the gate so that it does not open unless pulling the plug out. And, please make wiring with interlock so that robot would be operation ready OFF and motor OFF in the status that safety plug is pulled out or safety net is open.

 

(4)    When intending to operate the robot with the safety plug pulled out, wire the robot as a low-speed play mode.

 

(5)    For immediate emergency stop, install emergency stop button within operator’s easily accessible distance.

 

(6)    In case of no safety net, please install photoelectric switch, mat switch and so on instead of safety plug in all range of robot operation, and make robot to stop automatically when man goes into.

 

(7)    Operation area of robot (hazardous area) should be distinguished by the method like painting on floor.
