 Cup dispenser assembly
The cup d spens ng assembly cons sts of a storage un t w th 5, tube-shaped columns
that have an nternal d ameter of 78 mm (3.071”). The columns are jo nt by flanges
runn ng down the r full length, compr s ng a compact assembly. The assembly has a
pressure f tted star-shaped p ece that f ts ns de the gap left by the f ve tubes and serves
to mount t on the shaft that supports the cup d spenser .
Fig. 06
The total capac ty of the cup storage assembly s 250 cups.
The cup d spenser has a control system that employs
photocells to detect whether cups are present or not. When
the photocell beam s un nterrupted, the 12 V geared motor
ns de the d spenser starts and turns the storage assembly to
the next pos t on, controlled by the storage assembly pos t on
m crosw tch. If there are cups n the column, the r own we ght
pushes them down unt l they reach the hole on the d spenser
cover, block ng the l ght beam from the photocell system. If
every column s empty, the cup storage assembly w ll rotate
through 8 consecut ve pos t ons, to make sure that there are
no cups n any column, n wh ch case t w ll leave the mach ne
out of serv ce.
The cup for each serv ng s del vered by the cup d spenser . It cons sts of a 12 V geared
motor that s multaneously turns 5 cogwheels. The movement of these cogwheels
releases the cup rest ng on them at the same t me that t restra ns the other cups n the
stack (see f g. 07).
Note: The type of cup to be used has to be taken nto account.
Furthermore, w th n each class, the d spens ng cogwheels can be adapted to cup
d ameter at 0.5 mm (0.020”) ntervals. There s a cogwheel d splacement system that
allows you to br ng them closer to or further away from the cup centre. Follow these
steps to choose the most appropr ate system to d spense cups:
1. After dec d ng on the cup to be used, measure the d ameter at the base of the support
r ng and determ ne wh ch category the cup belongs to, 65-67 mm (2.559”–2.638”) or 67-
69 mm (2.638”–2.717”). Please note that the d spenser cogwheels, the cup collector
supplement and the cup sl de w ll be d fferent n each case.

2. Once you have def ned the cup n terms of ts class f cat on, choose the most
appropr ate cogwheel pos t on. To do th s, the cup d spenser assembly has 5
ntermed ate pos t ons for the 2 mm (0.079”) d stance between the largest and smallest
d ameter at 0.5 mm (0.020”) ntervals. Cogwheel pos t on 1 corresponds to the smallest
d ameter, wh le pos t on 5 s for the largest d ameter. The other pos t ons are obta ned by
add ng 0.5 mm (0.020”) ntervals. Choose the pos t on mmed ately above the closest to
cup d ameter (see f g. 07)
