6.3 PNEUMATIC SYSTEM
Connect the air source with a female quick release air coupling (Foster Series 3, #3003 or
equivalent) to the safety shut-off valve located on the pneumatic control panel (
Illustration 6.2
).
Air hose connections must have a minimum 1/2 in. (13 mm) ID. The PBC 6000 requires
compressed, clean, non-lubricated air. The supply must be capable of sustaining 90 PSI (6,2 bar)
of pressure and a volume flow rate of at least 400 SCFH (11,3 SCMH).
The pneumatics control panel is
equipped with a safety control valve.
While performing maintenance on the
PBC 6000, the pneumatic supply must
be turned “OFF” and locked out.
(
Illustration 6.2
) When shutting down
the machine, always be sure that the
heaters have COMPLETELY cooled
before turning off the pneumatic
supply. Not allowing the heaters to cool
will damage the heater cartridges and
the pneumatic tubing. The machine
usually takes approximately 10-20
minutes to cool down enough to turn off
the air supply under normal conditions.
6.4 LEVELING AND CENTERING
The quality of the bag seal depends on a number of factors. The most basic of these factors is
whether the bag is being fed into the machine correctly. When first preparing the machine for
operation, it must be properly placed vertically and horizontally in relation to the conveyor system.
LEVELING
To maintain an even fold on the bag top, the sealing operation of the PBC must run parallel to the
conveyor. To check this, measure the distance between the bottom of the carry through belts and
the surface of the conveyor belts. This distance should be the same at both the input and output
ends of the PBC. (
Illustration 6.3
) If there is a significant difference, the bag seal will be uneven
from leading to trailing edge of the bag. Make the necessary adjustments to achieve a parallel and
straight seal line.
