7 - CUP DISPENSER ASSEMBLY
It is a new functional unit, provided with the functions of
containing, releasing and positioning the cups.
Such feature is exclusive and patented.
The unit is composed of a cup holder turret with four columns with
a capacity of approximately 175 cups.
The turret is rotated by a 230 V 50 Hz synchronous ratiomotor
positioned in the same unit and activated by relay K 13. To make
cup loading easier the turret can be tilted and to achieve this it
needs to be lifted slightly and then pulled forward.
The system has an international patent.
The system operates as follows:
When a selection is made, relay K14 activates the cup release
ratiomotor (14) that rotates cam (16) clockwise, also driving pinion
(18) that connects the toothed rim of ring (22) by means of an idler
wheel.
When rotating, the ring also rotates the four worm gears (24) which
due to their special profile (snail) cause a cup to be released and
hold the other cups above.
The cup falls into the holding and shifting (32).
When the cam (16) rotates driven by the motor, it controls the
lever (36), as a consequence the fork (32) moves away from
the idle (starting) position until it reaches the cup release
position (Fig. 3).
It stays in such position long enough to receive the cup.
Then, completing the ratiomotor rotation, the fork brings the
cup into drink dispensing position (Fig. 2).
It remains in this position until a new selection is made.
Such position is determined by the microswitch (40) that also
gives the dispensing consent.
The fork is retained against the cam by a torsion spring, that
also allows manual movement of the fork to place a jug in the
dispensing compartment and an automatic return after the jug
is removed.
