VEND CYCLE
Several operations take place during the vend cycle: When a selection is made, the cam
and bucket rotate, product is dispensed and the bucket is then reloaded. The sequence
of these operations change slightly when the column’s depth setting is changed. With
the single depth setting, one purchase is made and the bucket is reloaded. The cam
sequence occurs one time per bucket revolution. With the double depth setting, two
purchases are made before the bucket is reloaded, and the cam sequence occurs twice
per bucket revolution. With the triple depth setting, three purchases are made and the
cam sequences three times per bucket revolution. With the quadruple depth setting, four
purchases are made and the cam sequences four times per bucket revolution.
PURCHASE SEQUENCE: (See Figure 11, quadruple depth setting pictured)
PS 1. Customer inserts money.
PS 2. The coinage reports credit to the vending machine electronic controller.
Established credit is displayed on the digital display located near the coin insert
slot.
PS 3. Customer presses a selection button.
PS 4. The controller receives the signal from the selection switch and (if sufficient
credit exists) energizes the corresponding vend motor.
PS 5. The vend motor rotates the bucket and cam. As the cam rotates, the motor
position switch actuator raises to the outer surface of the cam. This closes the
switch which signals the controller to remove credit.
PS 6. Product is immediately dispensed. The motor and cam continue to rotate until
the motor position switch actuator drops into the low part of the cam.
PS 7. Motor stops.

NOTE: The numbers on the cam reflect the number of vends allowed per cycle.
