At the beginning of the working day
•Check that the nozzle center is clean.
•(With humidifier for solvent-based colorants or without humidifier) 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).
•(With humidifier for water-based colorants) Check that the water in the bottle is not below the minimum level.
•Carry out system Purge (not necessary if the dispenser is equipped with Integrated Nozzle Valve System, INV).
Th i n g s to re m e m be r
•Never let the machine in the OFF position.
•In the canisters, stirring of each colorant takes place automatically (stirring times can however be customized).
•Be careful not to fill the canisters with too much colorant. In case of overfilling, 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 filling operations.
•Remember to update accordingly the canisters filling levels via the management software.
•(With humidifier for solvent-based colorants or without humidifier) 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).
•(With humidifier for water-based colorants) Top up the water bottle as soon as the minimum level is reached. Do
not exceed the maximum level.
At the end of the working day
•Refill the canisters.
•Update the canister filling 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.

3FEATURES
3.1 Description of the machine
The automatic dispenser is a device to automatically dispense fluid colorant products into containers (metal or plastic
canisters,cans or bins) of the size indicated in this manual,pre-filled with base,to produce finished 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. Control panel.
3. Upper covers.
4. Canister filling area.
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.
dd Some of the pictures in this manual were taken from prototypes; some details may differ in machines in
standard production.

3.2 Description of units
Canisters
The machine canisters can be of different capacities and are suitable for
containing the product to be dispensed.
Covers in the upper part of the machine provide access for filling the canisters.
Each canister has its own lid.
Nozzle center
The ends of the dispensing pipes coming from the canisters converge and are
fixed to the nozzle center, from which the tinting product to fill the can is
dispensed.
Integrated Nozzle Valve System (INV)
The INV system integrates the dispensing nozzle and the valve of each circuit
in a single cartridge.
The cartridges are mounted onto the specially designed dispensing head.
Valve opening (dispensing) and closing (recirculation) are operated by
compressed air, through a compressor positioned inside the machine.
Thanks to the air tightening characteristics of this system, the INV prevents
colorant from drying.
Shelf
The can shelf allows for the correct positioning of the can under the dispensing nozzle.
Manual shelf - The shelf is fixed 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.
Semiautomatic shelf - The shelf is commanded by the operator with the activation buttons (two-handed control); the
shelf stops when the can is detected by the photocell.
Automatic shelf - The shelf is managed by the computer that controls its movement and checks that the can placed on it
is actually the one selected for dispensing. A photocell checks for the presence of the can and that the shelf is correctly
positioned.
Roll conveyor
The foldable roll conveyor is mounted frontally on the canister module and facilitates the loading of heavy cans on the
shelf. It also features a step that makes canister refilling operations easier for the operator.
Can centering device
It is useful for placing the cans under the nozzle center, so that the can lid is punched in the middle and dispensing takes
place precisely into the hole created.

- 7 - COROB EVOFLX-LW
It is supplied on the machine accessorized with punching system, and is custom-made based on the size of the cans to
be handled.
The can centering device is also available as an optional accessory to the standard machine, useful for positioning pre-
punched cans right under the dispensing center.
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.
Nozzle Humidifier Cap
To prevent colorants from drying out in the nozzle center,the machine is equipped with a humidifier cap.
Puncher
The puncher is a device that perforates the can lid.
With semiautomatic puncher,punching is carried out by the operator by
pushing contemporaneously the semiautomatic shelf activation buttons
(two-handed control).
The shelf upward movement pushes the can resting on it against the puncher,
and with a downward movement brings it to the correct position for
dispensing.
No-Dry-Nozzle Humidifier
The humidifier for water-based colorants guarantees the nozzles are
constantly humidified. The air, humidified by the water contained in the
bottle, is transferred to the nozzles area. Based on the humidity level detected,
the system activates or shuts off whenever needed.
The humidifier for solvent-based colorants humidifies the nozzles when the
cap is closed. The solvent, contained in a small tank inside the cap, keeps the
nozzles area constantly saturated.
The two systems can be present individually or together according to the
tinting system used on the machine.
The rotating cap opens thanks to
the push applied to the opening
bar while the can is being
positioned. The cap closes when
the can is removed.When the cap
is open, the system confirms the
can presence to begin dispensing.
The automatic rotating cap is an
automatic cap managed by the
software, which opens it
automatically before dispensing
and closes it immediately
afterwards.
The automatic sliding cap is an
automatic cap which ensures that
the nozzles are hermetically sealed.
It is managed by the software,
which opens it automatically
before dispensing and closes it
immediately afterwards.
