1 Function and identification
1.1 Function
Automatic spray guns are used for
n automatic coating/marking of surfaces
n dosing of fluids
n placement of adhesive or marking points
Typical spray fluids are paints, dyes, adhesives, glazes, enamels, release agents, etc.
The spray fluid is fed into the automatic spray gun under pressure. This pressure is typically gener-
ated by pumps or pressure containers. The automatic spray gun is controlled via compressed air.
Upon opening, the control piston charged with compressed air initially opens the air nozzle and
then with a short delay the fluid nozzle of the automatic spray gun. Upon closing, initially the fluid
nozzle and then the air nozzle is closed in order to prevent a subsequent dripping of the spray
fluid.
For the precise control of the automatic spray gun, electrically-activated solenoid valves can be
used. Switching times of 60 ms can be achieved this way.
The spray fluid is atomised using compressed air. The geometry of the spray jet and the sprayed
quantity of the spray fluid can be adjusted with the following measures:
n Selection of the air and fluid nozzle
n
Changing of the atomiser air pressure
n Changing of the spray fluid pressure
n
Adjustment of the needle stroke on the regulator of the automatic spray gun.
The automatic spray gun also features the following additional characteristics:
n
Head section only in aluminium, hard-coated
n Head section with lower fluid connection
n Main element with flat jet controller
or with flat and round jet controller
