2.5.8 Air supply circuit example
shows an example of pneumatic supply circuitry .
(1) Place diodes parallel to the solenoid coil.
(2) If the factory's air pressure decreases, it may adversely affect the actual operations. As a preventive mea
-
sure, attach a pressure switch to the air source as shown in
so as to make the circuit stop the robot
in the event of air pressure drop. If the pressure switch does not improve the situation, use a device equipped
with a mechanical lock mechanism or a mechanism that clamps by spring pressure.
(3) The optional hand and solenoid valve are of an oilless type. If they are used, don't use any lubricator.
(4) Supply clean air to the vacuum generation valve when you use clean type robot.
