Function and application

The intended use of the vacuum block VABF-S4-1-V2B1… is to generate a vacuum. The generated vacu­
um and a suction gripper produce a force which is used to grip and transport a workpiece. The supply of
compressed air for vacuum generation is controlled by an integrated solenoid valve. The vacuum is
generated by actuating solenoid coil 12. The setpoint value set at channel B for the generated vacuum
is monitored via an integrated pressure sensor. Vacuum generation reverts to a self-holding phase after
reaching the setpoint value. The vacuum block controls the vacuum generation process independently
within the range of the set switching points (air-saving function). With the integrated solenoid valve, an
ejector pulse is activated and generated by activating coil 14 to release the workpiece safely from the
suction cup and to reduce the vacuum quickly. The length of the ejector pulse can be influenced by the
duration of the electrical pulse. The strength of the ejector pulse is influenced by the adjustable flow
control valve.
