Specifications
3.4 Pneumatic system
3.4.1 Compressed air connection
The compressed air servicing unit for non-oil
compressed air is fitted with a pressure
regulator valve and a gauge which keeps the
operating pressure constant virtually all the time.
The minimum operating pressure is 6 bar (87
psi). Pressure losses and fluctuations make it
necessary to set the supply pressure at the
control valve to 6 bar (87 psi). ( refer to Section
7 Maintenance/Repairs).
The available initial pressure must not be
allowed to fall below 7 bar (102 psi) and or
exceed 12 bar (174 psi).
The pressure control valve is not designed to be
able to deenergise the system pneumatically.
This is done by activating the electrical main
switch via the main valve which then vents the
system.
3.4.2 Creating a vacuum
The vacuum which is required to operate the
gripper is created using a vacuum injector
(Venturi principle). A blow out function is used to
place the components in the correct position.
3.4.3 Pneumatic valves
The system uses pneumatic 5/2-way valves
with multiple mounting plates. The integrated
vacuum nozzle in the valve block means that it
can only be used with oil-free air.
The vacuum valve air consumption is 27 l/min
(7.13 US gallons).
3.4.4 Pressure monitoring
The standard pneumatic system is fitted with a
pressure switch which acts as a pneumatic-
electronic converter (closer). If the pressure falls
below the 3 bar (44 psi) setting the robot sends
out a fault signal.
This is indicated in the display. The pneumatic
axis and gripper functions cannot operate safely
if the supply pressure drops below the specified
setting. The user shall be liable for any
consequential damage.
3.4.5 Central configuration
All the pneumatic elements are located on the
Z(X) slide except for the servicing unit.
