Safety risks related to end effectors
6.1 Gripper
If grippers are used to hold workpieces, inadvertent loosening of the workpiece must be
prevented.
6.2 Tools, workpieces
It must be possible to turn off tools like mill cutters, etc., in a safe and sure manner, e.g.
run down timers can ensure guards remain closed until cutters stop rotating.
Grippers must be so designed that the workpiece is retained in the event of an energy
failure or disturbances in the control system. It should be possible to release parts by
manual operation (valves).
6.3 Pneumatic, hydraulic:
Special safety regulations apply to pneumatic and hydraulic systems.
After shut-down, attention should be paid to residual energy in these system.
The pressure in pneumatic and hydraulic systems must be released before repair work is
commenced on them. Gravity may cause any parts or objects which are held by these
systems to drop. Dump valves should be used in case of emergency. Shot bolts should be
used to prevent tools, etc., from falling due to gravity.
Actions during operation disturbances
Disturbances in the working process entail other risks besides those associated with
regular operation, since such disturbances can necessitate rectification by hand.
Such rectification must be carried out by trained personnel only, who must be familiar
with the entire installation as well as the special risks associated with different
parts of it.
The industrial robot is flexible for use in different industrial applications. Caution must
always be observed and all work must be carried out to a professional standard and in
accordance with applicable safely regulations.
