BFT is born out of the need for innovation on inking systems in the world of flexographic printing. Since most inking systems are manual and free of washing automations, operators must adjust the speed of the pumps and remove the ink bucket manually and insert a bucket of water in the washing phase. For this, BFT has created the BFT Flexo inking and washing system and the BFT Carbon doctor blade unit. An integrated solution for your flexographic machines.

Two products to use separately, but. when integrated, achieve unparalleled levels of process optimisation. A flexible system. Just like the products you make.

Thanks to the excellent results obtained by the printing customers, the BFT Flexo systems are requested as an original equipment even by OEMs, that find technology and reliability in BFT Flexo systems but also a considerable saving compared to the internal management of the washing system.

It automates the inking and washing processes, recovering ink and halving consumption

The only thing you need to do by hand is touching the screen.Most inking systems include manual processes, including the pump adjustment and washing. Operations that require prolonged machine downtime and a continuous assistance by the staff.

The BFT FLEXO systems are completely automatic: to start any cycle, just press a button on the touch screen.

It remembers everything you doProcess standardisation

The operator can easily set the speed of the pumps from the screen to optimise the inking phase and the washing phase. Setting is saved and linked to the order to be resumed over time.

Don’t waste “liquids” Ink recovery

Thanks to the possibility of reversing the delivery pump, the system can recover all the residual ink that is washed and is wasted when using other systems.

Quick and thorough washing The washing cycles are fast and precise at every colour change and ensure the complete cleaning of the anilox cells.

The surprise of not having surprisesAn eye on the statistics

All the components of the system carry out a self-diagnosis showing the life of each component to the operator and signalling any necessary maintenance in advance, avoiding any costly downtime.

Description of the system

INTERNAL CLEANING

Before changing the bucket, the system carries out, by means of the specific cycle, an internal cleaning of the bucket-side pipes, thus avoiding any type of contamination of the next colour. Moreover, if the system is inactive for a defined time, it automatically carries out, thanks to a special algorithm, an internal cleaning cycle to guarantee the total cleaning in view of an extended inactivity.

SOAP2CLEAN*

For periodic cleaning, or to increase the daily cleaning performance greatly, use the cleaning solution dosing function in the system. By setting the amount of cleaning solution additions on the screen, the system will automatically add the solution during the cleaning phase.

QUICK WASH

To carry out quick washes, for a job change with similar colours, and thus optimise timing without any waste, you can use the QuickWash function. The operator can select this function with a simple touch.

PULSE-FREE INKING

inking is managed by a peristaltic pump that reduces the pulsations to a minimum and a return pump to increase the ink circulation speed and avoid gelling in the doctor blade unit

INK RECOVERY

The system recovers ink from both pipes, allowing the maximum ink saving

PREWASHING AND WASHING WITH 50% WATER SAVING

Using an internal tank to store the water resulting from the last washing cycle, the system uses the same water twice in order to use half the water volume. The cycle ends with the cleaning of the circuit using clean water or solvent to avoid contamination in the subsequent printing operation

CPC

The operator can constantly monitor the pressure status

and the doctor blade chamber position thanks to the CPC

system that can be integrated in the PLC touch screens.

The system guarantees the control of the closure

in the correct position of the doctor unit, it also allows

standardising the process, memorising the pressures

used, so as to reduce the consumption of the blades.

The algorithm can independently compensate

blade wear over time.

24 25

TemperatureTemperature control is the most important variable

to standardise the characteristics of the ink being

printed. Both viscosity and Ph are temperature

functions, stabilising the temperature, the most

important variable is eliminated.

Ph

The PH control is integrated in the internal manifold

so that it is always washed during the washing phase.

The probe is easily removable for maintenance

and the PH graph can be traced and saved job after job.

Checking takes place via a pressure line and a valve

located on the return line before the ink returns

to the bucket.

T-R Ink temperature reading and traceability by means of graph sensor

T-RW Reading and use of an inspectable piston heat exchanger for the cooling. The heat exchanger can be connected both to the cooling line of the machine, if there is one, and to a new refrigerated line

T-RWC Temperature control by means of a valve acting on the exchanger, once set the desired temperature, the system will maintain it

Viscosity Viscosity reading is made by established sensors

on the printing market. The BFT FLEXO system

intervenes on its control algorithm and integrates

the valve inside.Traceability and setting are included

in the system software.

VS-R Ink viscosity reading and traceability by means of graph sensor

VS-RW Reading and use of an inspectable piston heat exchanger for the cooling. The heat exchanger can be connected both to the cooling line of the machine, if there is one, and to a new refrigerated line

VS-RWL Reading by sensor and correction by pneumatic valve. Supply of pressure line for central drum versions. Tank excluded

Sensors

FLOW SENSORS

Determines if there is ink in the return line before

returning to the bucket.

With this sensor you can determine:

• pump breakage

• lack of ink in the bucket

• general circulation problem (clogged filters,

bodies obstructing the passage)

LEVEL SENSORS FOR EXTERNAL TANKS

For those using external tanks for the discharge

and water/solvent lines for washing,

level control is essential for the system to work.

The sensors are capacitive in zone 1 ATEX class.
