MELTER OPERATION
After this point, the system moves down automatically without the need to
keep pushing the bimanual control. The buzzer stops sounding: the risk
dosen’t exist already.
Whenever the plate is moving down into the drum, it is necessary to open the
manual purge valve to prevent the drum from being pressurized. Once the
adhesive is released by the valve, it may be closed and operated as normal.
When the corresponding sensor on the cam system, which position has been
selected previously, detects that the adhesive in the drum will end shortly, the
system warns by the external signal or the light tower (if it is present —red
light—). A new full drum can be prepared to replace the empty one.
When the platen reaches the bottom of the drum (detected by the
corresponding sensor on the cam system), the platen stops, also the pump
and the system is waiting for the order to raise once again. At the same time
the buzzer advises of the empty drum (lowest position of the platen). The
buzzer can be deactivated by bimanual control.
With the system at the lowest position the amber button ‘Platen up’ blinks
showing the possibility to move up the platen. Pushing it the platen moves up
until the button is re-push or it reaches the highest position (detected by the
corresponding sensor on the cam system), where it stops and the button light
goes off.
Automatically, while platen is moving up, the air input for aeration is activated
to avoid vacuum efects inside the drum. It is necessary to insert previously
the aeration bar (manual system) if the drum melter has not the automatic
aeration option installed. Any case it is possible to activate this signal
manually by the blue button ‘Air in’.
Placing a new drum
With the platen in the highest position put the new drum placing it on the
rounded positioning base (1). This fixation avoids horizontal displacements of
the drum. The drum must not have dents or deformations.
Place the drum retainer to adjust its the vertical fixation when the platen
moves up out of the drum (2).
Apply a light layer of grease on the plate closure seal (3).
Remove the rod from the purge hole. To do so, turn it 1/4 turn to the left and
pull up. Now, the rod will up a level and will be in the protection zone.
Note: This step is not necessary to remove the rod completely.
