5) Signaling methods for workers of related equipment
6) Types of malfunctions and how to distinguish them
Please ensure "working regulations" are appropriate to the robot
type, the place of installation and to the content of the work.
Be sure to consult the opinions of related workers, engineers at
the equipment manufacturer and that of a labor safety consultant
when creating these "working regulations".
To prevent anyone other than the worker from accessing the start
switch or the changeover switch by accident during operation,
display something to indicate it is in operation on the operation
panel or teach pendant. Take any other steps as appropriate,
such as locking the cover.
When performing jobs within the robot's restricted space, take
any of the following steps to ensure that robot operation can be
stopped immediately upon a malfunction.
(1) Ensure an overseer is placed in a position outside the robot's
restricted space and one in which he/she can see all robot
movements, and that he/she is devoted solely to that task.
An emergency stop device should be activated
immediately upon a malfunction.
Do not permit anyone other than the worker engaged for
that job to enter the robot's restricted space.
(2) Ensure a worker within the robot's restricted space carries
the portable emergency stop switch so he/she can press it
(the emergency button on the teach pendant) immediately if
it should be necessary to do so.
Before starting work such as teaching, inspect the following
items, carry out any repairs immediately upon detection of a
malfunction and perform any other necessary measures.
(1) Check for any damage to the sheath or cover of the external
wiring or to the external devices.
(2) Check that the robot is functioning normally or not (any
unusual noise or vibration during operation).
(3) Check the functioning of the emergency stop device.
(4) Check there is no leakage of air or oil from any pipes.
(5) Check there are no obstructive objects in or near the robot's
restricted space.
