6.1.3 Precautions for using robot
The safety measures for using the robot are specified in the "Labor Safety and Sanitation Rules". An outline of
the rules is given below.
(1) Robot installation
・ Secure sufficient work space required to safely perform work such as teaching and maintenance related to the
robot.
・ Install the controller outside the robot's motion space. (If a safety fence is provided, install outside the fence.)
・ Install the controller where the entire robot operation can be viewed.
・ Install display lamps, etc., to indicate the robot's operation state.
・ Securely fix the robot arm onto the fixing table with the designated bolts.
(2) Prevention of contact with operator
・ Install a safety fence or enclosure so that the operator cannot easily enter the robot's motion space.
・ Install an interlock function that will stop the robot if the safety fence or enclosure door is opened.
(3) Work procedures
・ Create and observe work procedures for the robot teaching, operation, inspection and emergencies.
・ Create hand signals to be followed when several operators are working together.
・ Create displays such as "Teaching in Progress" and "Inspection in Progress" to be put up when an operator is
in the robot's motion space so that other operators will not operate the operation panel (controller, control
panel).
(4) Training
・ Train the operators about the operations, maintenance and safety required for the robot work.
・ Only trained and registered operators must operate the robot.
Participation in the "Special training for industrial robots" sponsored by the Labor Safety and Sanitation Com
-
mittee, etc., is recommended for safety training.
(5) Daily inspection and periodic inspection
・ lways inspect the robot before starting daily operations and confirm that there are no abnormalities.
・ Set the periodic inspection standards in view of the robot's ambient environment and operation frequency, and
perform periodic inspections.
・ Make records when periodic inspections and repairs have been done, and store the records for three or more
years.
6.1.4 Safety measures for automatic operation
(1) Install safety fences so that operators will not enter the operation area during operation and indicate that
automatic operation is in progress with lamps, etc.
(2) Create signals to be given when starting operation, assign a person to give the signal, and make sure that the
operator follows the signals.
6.1.5 Safety measures for teaching
Observe the following measures when teaching, etc., in the robot's operation range.
(1) Specify and follow items such as procedures related to teaching work, etc.
(2) Take measures so that operation can be stopped immediately in case of trouble, and measures so that oper
-
ation can be restarted.
(3) Take measures with the robot start switch, etc., to indicate that teaching work is being done.
(4) Always inspect that stop functions such as the emergency stop device before starting the work.
(5) Immediately stop the work when trouble occurs, and correct the trouble.
(6) Take measures so that the work supervisor can immediately stop the robot operation when trouble occurs.
(7) The teaching operator must have completed special training regarding safety. (Training regarding industrial
robots and work methods, etc.)
(8) Create signals to be used when several operators are working together.
6.1.6 Safety measures for maintenance and inspections, etc.
Turn the power OFF and take measures to prevent operators other than the relevant operator from pressing the
start switch when performing inspections, repairs, adjustments, cleaning or oiling.
If operation is required, take measures to prevent hazards caused by unintentional or mistaken operations.
(1) Specify and follow items such as procedures related to maintenance work, etc.
(2) Take measures so that operation can be stopped immediately in case of trouble, and measures so that oper
-
ation can be restarted.
(3) Take measures with the robot start switch, etc., to indicate that work is being done.
(4) Take measures so that the work supervisor can immediately stop the robot operation when trouble occurs.
(5) The operator must have completed special training regarding safety. (Training regarding industrial robots and
work methods, etc.)
(6) Create signals to be used when several operators are working together.
