3 – VENDING SYSTEMS
“Sfera” is
a vending machine belonging to the S&F range, with
product dispensing by means of the rotation of spirals.
During their rotation the steel spirals, because of their
“auger
effect”
, push forward the product loaded onto the tray,
dropping it in the dispensing compartment.
As an optional kit on request, some versions are provided with
infrared barriers with receiver/transmitter diodes and transistors
that detect the falling product and signal to the software that
the product was released correctly. In the event the barrier is
not interrupted, the option of trying the selection again is given;
if the selection fails again, the option of another choice or
refund is given. (SW option)
The tray is modular, and by simply moving the partitions it is
possible to change it from single to double or triple; there are
also some specific accessories for dispensing special products.
Different pitch spirals are provided, to be able to dispense 20 to
76 mm wide products.
In addition the spirals can be right or left hand, to be used in
double compartment configuration with double spiral. The
ratiomotor is fitted with a “minidip” switch to reverse the
rotation.
The tray is held into position automatically by a stop located on
the guides; to slide out the tray it need to be lifted slightly from
the front and then pulled fully to the second safety stop. To
extract it completely it needs to be lifted further and then
removed (after disconnecting the electrical connector located on
the right side). As standard feature, the vending machine is
provided with 6 trays, however up to 8 trays can be fitted by
reducing the space between trays
(see configuration instructions).
