COROB™ FLEX 900
COROB™ AUTOMATIC DISPENSER
QUICK GUIDE
At the beginning of the working day
• Check that the nozzle center is clean.
• Check that the sponge is clean and saturated; if it is necessary to saturate, use only appropriate liquid (the
choice of the liquid depends on the nature of the colorants, and must be done directly by the manufacturer
of the products used).
• Carry out system Initialization and Purge.
Things to remember
• Never let the machine OFF.
• In the canisters, stirring of each colorant takes place automatically (stirring times can however be
customized).
• Be careful not to ll the canisters with too much colorant. In case of overlling, act as indicated in the user’s
manual.
• The colorant to be poured inside the canisters must be stirred manually. Do not use automatic shakers.
• Close the canisters with their lids right after lling operations.
• Remember to update accordingly the canisters lling levels via the management software.
• The sponge must be saturated at least twice a week (the frequency of intervention is indicative, since it
depends on the nature of colorants and the environment conditions).
At the end of the working day
• Rell the canisters.
• Update the canister lling levels in the management software.
• Shut down the computer. Do not shut off the machine.
It is recommended to carefully read the user’s manual.

2 SAFETY
2.1 General warnings
COMPULSORY
• Read the user’s manual carefully before carrying out any operation on the machine.
• The machine must be used only for its intended purpose.
• Pay close attention to the signs on the machine.
• The substances that may be used on the machine -- such as colorants, paints, solvents, lubricants and
cleansers -- may be hazardous to your health; handle, store and dispose of these substances in keeping
with current regulations and the instructions provided with the product.
• Only qualied and appropriately trained personnel (MAINTENANCE TECHNICIANS) are authorized to access
the machine parts protected by panels for maintenance and repair interventions.
• During routine maintenance operations, scrupulously follow the safety instructions given in the corresponding
chapters before accessing the dangerous area.
PROHIBITED
• The OPERATOR must not carry out operations reserved to the MAINTENANCE TECHNICIAN. The manufacturer
CANNOT BE HELD RESPONSIBLE for damages deriving from the non-observance of this prohibition.
• It is strictly forbidden to bypass or disable the protections and any safety devices present on the machine.
• The panels must be kept closed at all times.
• THE MACHINE IS NOT EXPLOSION-PROOF AND MUST NOT BE USED IN AREAS AT RISK FOR
EXPLOSION.
• Do not stare the light source of the Laser Bung Hole Locator (Class II laser product).
• If the machine catches re, never use water. Use only dry powder or carbon dioxide re extinguishers, and
strictly follow the instructions and warnings indicated by the manufacturer and listed on the extinguisher.
ELECTRICAL DANGER
• In the event of a sudden power outage, when power returns the machine will automatically be switched on
to allow the automatic processes to prevent products from drying out.
• The machine must not be powered by a power source having specications other than those listed on the
identication plate.
• Incorrect grounding may lead to the risk of electrical shock; always plug the machine into a socket that
ensures proper grounding. The line must be protected from overloads, short-circuits and direct contacts
according to current accident prevention regulations.
• To prevent any risk of electric shock or injuries, the machine must be used indoors only.
• Always unplug the power supply cable from the socket outlet before carrying out any maintenance operations.
• The machine is isolated from the power supply line when the power cable is disconnected; it must therefore
be installed near an easily accessible mains socket outlet.
• Do not use extension cords to power the machine.
• Do not use multisockets to connect other equipment to the same socket that powers the machine.
• Periodically check the condition of the power supply cable; if it is damaged, replace it with a new cable

3.1 Description of the machine
The COROB™ FLEX 900 automatic dispenser is a device to automatically dispense uid colorant products into
containers (metal or plastic canisters, cans or bins) of the size indicated in this manual, pre-lled with base, to
produce nished products such as paints, dyes, enamels, and inks of the desired hue, chosen by means of the
machine management software.

The dispenser consists of:
1. Dispensing area and can handling system.
2. Off-line button.
3. Upper covers.
4. Canister lling area.
5. Computer support surface.
The dispenser is fully managed by a normal personal computer that can be provided upon request, since it is
not supplied as standard together with the machine. The manufacturer can also supply a wide range of software
applications to manage all of the machine’s functions.

10 - FEATURES
COROB™ FLEX 900
3.2 Description of units
Canisters
The machine canisters are suitable for containing the product to be dispensed.
Covers in the upper part of the machine provide access for lling the canisters.
Nozzle Center
The ends of the dispensing pipes coming from the canisters converge and
are xed to the nozzle center, from which the tinting product to ll the can is
dispensed.
Shelf
The can shelf allows for the correct positioning of the can under the dispensing
nozzles.
The Lift manual shelf is xed to the machine and can be raised or lowered
by the operator. The shelf is provided with a locking handle that must be
pulled to release the shelf and allow it to be moved to the desired height.
Can centering device
The can centering device is useful for positioning pre-punched cans right under
the dispensing center and is custom-made based on the size of the cans to be
handled.
Bung Hole Locator (B.H.L.)
This is a system that emits laser beams that allow the positioning of pre-punched
cans, so that the hole is in line with the center of the dispensing nozzles.

FEATURES - 11
COROB™ FLEX 900
Nozzle Humidier Cap
Colorants tend to dry out; this tendency may be more or less strong depending on the type of colorant and
the environment conditions (temperature, relative humidity, etc.). To prevent colorants from drying out in the
nozzle center, the machine is equipped with a humidier cap which requires constant maintenance.
The Sliding cap is a simple cap, which opens thanks to the push applied
to the opening bar while the can is being positioned. The cap closes when
the can is removed. The system checks that the cap is properly opened
and conrms the can presence to begin dispensing.
The Sliding Autocap is an automatically activated cap, whose movement
is managed by the application program, which opens it automatically
before dispensing and closes it automatically immediately afterwards. A
photocell prevents dispensing from taking place when no can is resting
on the shelf.
