CPI COTI - Mixing System; Moving Dispense Head: COTI; Cup Dispense Unit: COTI

Secon 7 - Technical Informaon
4. To ensure a free ow of ingredient powder and granules it is essenal that they are
kept completely dry. This is achieved by extracng steam from the mixing system
using an extract fan. The electrical supply for the LINEA extract fan is 24VDC and for
the COTI machines it is 110V AC.
Note: The fan runs connuously whilst the machine has power.
5. Espresso machines: Coee beans are stored in a bean container and are dispensed
into the CoEx® Brewer via a 110V AC grinder located under the bean container outlet.
The amount of beans dispensed from the container is controlled by the vending
machine controller and may be adjusted via ming constraints set in the Engineers
Program.
7.4 Mixing System
1. The mixing system ulises 24V DC 13000 RPM motor assemblies and mixes ingredient
with hot water from the heater tank.
2. The mixing units are front mounted and secured by a single xing screw. For servicing
the complete unit can be quickly and easily removed.
7.5 Moving Dispense Head: COTI
1. COTI machines are ed with a moving dispense head mechanism. This allows for a
quicker and more direct cup drop and also helps to prevent cross contaminaon of
drinks. The head features two separate dispense posions depending upon the drink
being dispensed.
2. The mechanism is operated by a 24V DC 48 RPM motor. The motor is connected to a
pinion which engages with a rack on the dispense arm. This mechanism is used to
move the dispense head backwards and forwards.
3. A micro switch, ed to the rear of the dispense head chassis detects the home
posion (head withdrawn/not dispensing). An opcal sensor is also ed and this
works in conjuncon with a decoder aached to the rack to determine the posion of
the dispense head.
4. A moulded dispense head mounted at the front of the unit connects the tubes from
the various mixing systems, brewers and hot water to separate dispense nozzles.
Note: Dispense pipe informaon is shown in Secon 9.
7.6 Cup Dispense Unit: COTI
1. Cups (either paper or plasc) are stored in tubes which are located above the cup
dispense unit. The unit incorporates a 24V DC, motor for indexing the turret over the
cup drop unit as required.
2. The cups are separated and ‘dropped’ by a cup ring. The cup ring comprises of ve
splier cams operated by a 24V DC motor which is controlled by the vending machine
controller.
3. The cup level is monitored by an electronic system. An infrared LED (cup sensor
transmier) is posioned in the cup assembly above the cup splier with an infrared
detector (cup sensor receiver) mounted directly opposite.
