Program Settings:
Cure parameters (also called “Programs”), are
usually set at the main screen on the control
Kiosk (Figure 1). These parameters can be saved
with user-defined names, and can be recalled by
pressing a button on the kiosk, or scanning a
barcode (on devices with the optional scanner
software).
Figure 1: Main Control Screen
Cure parameters are applied to products laid on
the belt when the parameters are active on the
main screen. It is possible to change the
parameters several times while laying several
different products on the belt, and have the
correct cure parameters follow the product down
the belt and through the heat chamber. Consult
the “Load Detect” section of this manual for
more information on changing parameters
between products.
Temp:
This is the cure temperature of the product. The
Firefly Curing System will attempt to bring the
product up to this temperature as quickly as
possible, and maintain this temperature as the
product moves through the dryer.
Belt Speed:
This is the amount of time (in minutes and
seconds) the product will receive heat from the
heating elements. This does not include time
spent outside the heat chamber or under the
exhaust section.
The Firefly Curing System uses an intelligent
algorithm to control the belt speed. When
products are not being cured, the belt runs at a
default (usually fast) speed. Once a product is
detected, the belt will adjust its speed based on
the Program settings for that product. The “Belt
Speed” that was defined in the product’s
Program settings, is the exact amount of time
that it spends in the heat chamber.
If a second product, requiring less cure time,
were to enter the heat chamber at the same time,
the bulbs above that second product would turn
off once it reached its set amount of time. This
means that multiple different products with
varying cure times could run down the same belt
without interfering with one another.
Convection Top & Bottom:
Each Firefly Module (“Drone”) has independent
Top and Bottom Recirculation Air (also called
“Convection Air”). The convection air setting is
saved with each program, and thus changes as
products traveling through the conveyor calls for
more or less air.
Figure 2: Convection Air
Top air is advantageous when drying certain
water based inks, such as, digital and
solvent-based prints. However, it has a negative
effect on the performance of certain plastisol
inks, especially when attempting to control dye
migration on polyester products.
