3-2 3-FEATURES
COROB™ TATOCOLOR
The machine may be accessorized with an optional device to center the hole of the pre-punched
can under the nozzle center with a laser (Bung hole locator or B.H.L.), this is useful for those
using pre-punched cylindrical or differently shaped cans.
The structure of the dispensing section has been designed to allow the computer, monitor and
keyboard to be housed on the machine. An auxiliary support plate for the computer may be
requested as an optional.
3.1.2 COROB™ TATOCOLOR TA

2. Right side canister section
3. Left side canister section
Figure 3-2 - COROB™ TATOCOLOR with ABS panels - model TA
3.2 Description of groups
This chapter gives a detailed description of the main machine groups.
3.2.1 Canister section
(Figure 3-3)
The side sections of the machine house canisters (1) suitable for containing the product to be
dispensed. To keep the colorant to be dispensed in the best possible condition of storage and
homogeneity, each canister is equipped with a stirrer with slanted blades (2), powered by a gear-
3

3-FEATURES 3-3
COROB™ TATOCOLOR
motor (3) attached beneath the canister itself. The materials of which the shaft and stirrer blades
are made are compatible with the type of product that the canister is to contain.
At regular, programmable intervals, the management computer activates the stirrers for a
programmable time, one after another; the stirring time and interval between cycles may be set
based on the physical nature of the products in the canisters.
The rotation speed of the stirrer prevents the formation of air emulsions and other negative
effects that could interfere with the machine's performance.
During dispensing, if stirring is in progress it is interrupted to allow suitable working conditions;
the stirring cycle will start again at the end of dispensing.
In addition to stirring, recirculation takes place at regular programmable intervals to keep the
colorant to be dispensed in ideal condition; this process circulates the colorant, which travels
throughout the dispensing circuit and returns to the canister through a special fitting (4).
The canister sections house the COROB™ pumps (5), made of wear-resistant materials that
maintain their characteristics over time. All pumps are driven by a single gear-motor (6) located
in the dispensing section.
Each pump has a filtering unit (7) that serves to trap any impurities that may be present in the
colorant, protecting the life-span, integrity and precision of the pumps.
Figure 3-3
3.2.2 Dispensing section
(Figure 3-4)
The dispensing section (also called the dispensing center) is where the ends of all of the
machine's dispensing circuits (1) converge, fixed to the nozzle center (2), which dispense the
calibrated amounts of colorant.
The part including the nozzle center and can positioning area is known as the dispensing area.
The upper compartment of the dispensing section contains the same number of electrovalves (3)
as circuits installed on the machine, on a single support surface.
The electrovalves are three-way/two-position valves, suitable for handling viscous, abrasive, and
chemically aggressive products.

3-4 3-FEATURES
COROB™ TATOCOLOR
The status of the electrovalve determines whether the colorant is discharged (dispensed) or
returned to the canister (recirculation).
The lower compartment of the dispensing section also contains the gear motor (4) that drives the
pumps, and the control electronics that allow the machine to run at a steady speed during
dispensing operations.
Product is prevented from drying in the nozzle center area by a humidifier cap.
The structure of the dispensing section has been designed to allow the computer, monitor and
keyboard to be housed on the machine. An auxiliary support plate for the computer may be
requested as an optional.
Figure 3-4
3.2.3 Shelf for can positioning
COROB™ TATOCOLOR features an internal dispensing center, which includes the dispensing area
and can handling system built into the machine chassis.
The shelf is a system that allows to raise the can and place it correctly in correspondence with the
dispensing nozzles.
The cans, of different sizes, containing the base product to be colored are loaded and positioned
by a manual shelf (1) (Figure 3-5) fixed to the machine that can be raised or lowered by the
operator.
The shelf is provided with a locking handle (3) (Figure 3-6) that must be pulled to release the
shelf and allow it to be moved to the desired height. Once you have reached the desired height,
release the handle to lock the shelf in place, allowing you to rest the can on it.
The check of can presence is carried out by the photocell (2) (Figure 3-5), placed at the
appropriate height in the dispensing area (only when automatic sliding cap is present).

3.2.4 Humidifier cap
By their very nature, colorants tend to dry out; this tendency may be more or less strong
depending on the type of colorant and the environment conditions where the dispenser is
installed, such as the temperature, relative humidity, etc.
The machine is equipped with a humidifier cap to keep the dispensing nozzle center at a moisture
level to prevent the colorant from drying out; this device contains a moistened sponge.
The sponge is housed inside the cap, and must be cleaned and moistened periodically (chapter
8.4).
Sliding cap
(Figure 3-7)
This 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. Dispensing is allowed only if the can is
present, that is to say when the cap is properly open.
Automatic sliding cap or sliding Autocap
(Figure 3-8)
This is an automatically activated cap (Autocap) which opens automatically when the can placed
on the shelf obscures the photocell, and closes automatically when the shelf is lowered and the
photocell disengaged or when the can is removed from the shelf.

3.2.5 Punch & plugger - TATOCOLOR TA only
The punch & plugger is a device that perforates the can lid, then (after dispensing) inserts a
plastic plug in the hole made.
On the machine accessorized with the punch, a can centering device (custom-made) can be
mounted as an optional accessory on the shelf surface, essential for aligning the cans with the
nozzle center, so that the can lid is punched in the middle, dispensing precisely into the hole
created, and correctly inserting the plastic plug. The can centering device is also available as an
optional accessory to the standard machine.
Manual punch
(Figure 3-9)
The operator punches the can manually, by pulling on the suitable lever (2) that lowers down the
manual punch (3); this requires that the enabling button (1) be simultaneously pressed, for
obvious safety reasons (chapter 7.3.2). Punching is allowed only if a can has been correctly
loaded into the machine.
Manual plugger
(Figure 3-9)
The plastic plug is inserted by pulling on the suitable lever (2) that lowers down the manual
plugger (4); this requires that the enabling button (1) be simultaneously pressed, for obvious
safety reasons (chapter 7.3.4). The plug insertion is allowed only if a can has been correctly
loaded into the machine.
The green enabling button (1) is active (and can therefore release the punch/plugger lever)
only if it is illuminated, that is when the following conditions occur: correct positioning of the can
and opening of the sliding Autocap.
