5.2. Pneumatic system
The pneumatics are a key component of the
robot system. They provide a ”source of energy”
for the auxiliary axes and the gripper clamping /
vacuum circuits.
5.2.1 Directional control valves
These valves shut off, release and divert the
compressed air channels.
Electromagnetic valve
These valves adjust the auxiliary axes (basic
and end positions) and set/reset the clamping
circuits.
Principle:
Electrical, indirectly activated 5/2 bistable,
directional valve. The valve remains in position
after it has been adjusted until it is reset by a
counter signal.
Solenoid valve
Principle:
Electrically activated 5/2 monostable directional
control valve Once it has been set, the valve
only remains in position while the adjusting
signal is activated. A mechanical spring resets
the valve when the signal is deactivated.
5.2.2 Vacuum suction nozzle
A vacuum is created inside the vacuum
generator by the compressed air passing
through it (Venturi principle). The vacuum
generator is switched on/off by an input signal.
The housing has an integrated filter to keep out
any dirt.
