Our custom developed infared technology is installed in the delivery
bin to insure the dispensing of the product. When the selection is
made, the transaction is complete only if the product breaks the
mesh of the infared beam.
If the product is not sensed, the spiral
rotates in steps of 1/3 rotations until the product drops. If there
is no product sensed, then the motors are returned to home and the
selection is made SOLD OUT and the customer will have the
opportunity to make another selection.
