6.8 SETTING THE TEMPERATURE
The temperature of the heaters is controlled and regulated by the temperature controller located on
the control panel. (
Illustration 6.9
) The temperature should be set based on the following criteria:
1. Type of adhesive used on the bag. (i.e. glue melting point)
2. Speed of the conveyor system.
3. Room temperature.
4. Ambient bag temperature.
5. Relative humidity of the bag material.
Since the bag and glue take time to heat up, the faster the system is required to seal bags, the
higher the temperature setting must be. Keep in mind that every time the conveyor and machine
speed is changed the temperature should be changed.
Leaving the temperature set higher than
needed for a new setting, my cause the bag or glue to char. THIS IS A FIRE HAZARD AND
MUST ALWAYS BE AVOIDED!
6.8.1 DETERMINING THE CORRECT TEMPERATURE
The PBC 6000 is designed to accommodate a variety of heat-activated glues. Each type of bag
could require a different temperature setting for a variety of production line speeds. Check with the
bag supplier, to determine the temperature needed to melt the glue. Due to the rate at which the
bags pass through the system and the thermal properties of the bag, the temperature will have to be
set higher than the glue’s melting point.
For safety, always start at a lower temperature
and slowly increase the setting as needed.
For many common bag types and a line running
at
40 –45 FPM (12,2 –13,7 MPM)
, the temperature can be set at
450
o
F (232
o
C)
.
The room temperature and humidity can affect the seal quality. It is important to always keep in mind
all conditions while operating the PBC 6000. The temperature of the bag material when it passes into
the machine will also determine the setting for the temperature. It is best to allow the bags to reach
room temperature before filling and sealing them. Always allow the machine to heat up completely
before adjusting the temperature. (Approximately: 20-30 minutes)
The temperature should be adjusted accordingly while the machine is being operated. Take time
during the operation of the machine to inspect the seal quality and then adjust the temperature as
needed. Keep a record of the ambient room temperature, bag type and the production line speed in
order to reduce the set up time for determining the temperature settings, when changes occur.
