AUTOMATIC CLEANING SYSTEM

Solutions for the professional of flexography and rotogravure

The I-ACS Automatic Cleaning System supplies ink to the Doctor Blade Chamber through an adjustable flow and ensures at all times the necessary volume of ink in the chamber for a correct supply. Once the work is finished, the system allows to clean the entire ink circuit and can clean all the printing bodies simultaneously.

We have two versions of the I-ACS system, a basic system with a single impulse pump and return from the chamber by gravity and the complete system with double pump that ensures the pressure inside the doctor blade chamber and optimizes solvent / water consumption as well as minimizes cleaning times.

ALL THE ADVANTAGES OF THE LEADING SYSTEM OF CLEANING FOR FLEXOGRAPHY AND ROTOGRAVURE
  • The I-ACS system centrally manages all the operation of ink supply and cleaning of the printing bodies in the minimum possible space (design in tower layout). Allows simultaneous cleaning of all printing bodies.

  • It minimizes the consumption of solvent / water that cleans in each process thanks to the reuse of solvent / water that has been used in previous cleanings

  • Once the print job is finished, the majority of ink found in the system and in the chamber is recovered to the ink cube and can be used in future work.

  • The materials used in its manufacture are of proven quality and leading brands in the market which is reflected in a high reliability and long life of the components, as in the case of the membranes of the pumps with a service life of 50,000,000 cycles.

  • This system is completely compatible with the rest of the modules of the Ink Control Solution (I-ICS), being able to add concentration control, temperature control, etc …

  • The modular design by groups of printing allows the complete replacement of a group in case of failure simplifying the tasks of maintenance and the times of stopped machine in case of failure.

HOW THE AUTOMATIC CLEANING SYSTEM WORKS

In the pumping process, the equipment employs a pneumatic pump to absorb in from the standard cube and drive to the doctor blade chamber. A second pump* absorbs from the doctor blade chamber. The working frequency ratio of these two pumps and consequently the flow of impulsion and absorption are configurable separately so as to avoid any problem of over-pressure in the chamber that could generate overflows.

The system allows to configure different cleaning processes depending on the needs, quick cleanings to use similar colours or deep cleaning for changes from black to white without any contamination. In any case, the common cleaning process begins with emptying the ink circuit and the doctor blade chamber for practically total reuse (see technical characteristics) of the ink in future work. Subsequently and through an external pump, it is introduced into the solvent or water circuit (depending on the type of ink) that has already been used in previous cleanings to remove the remains of ink that could remain in the circuit. This solvent / water is again removed from the system by another external pump and stored in a tank for future reuse use. In a second cycle, the system performs the same procedure but this time using clean solvent / water as a rinse to ensure complete cleaning of the circuit and the doctor blade chamber. Through this procedure and the combined use of reused solvent / water and clean solvent / water, it is possible to minimize consumption in each cleaning without sacrificing perfect results.

*Depending on model

PHASE OF INK

2 electronic control pneumatic pumps:

  • 1st pump directs the ink from the can to the chamber.
  • Return driven through the 2nd pump to the can.
  • The power of the 2nd pump is controlled electronically to be somewhat higher than the drive and create negative pressure inside the chamber.
Better anilox inking
Avoid spills

EMPTYING PHASE

Electronic redirection of pumps:

  • Both pumps are redirected to empty the circuit in both directions.
  • Once the emptying has finished the user can change the cans I-ACS Complet starts washing automatically.
Faster and better emptying
Easier and faster cleaning

CLEANING CYCLE

I-ACS Complet directs recycled water / solvent from the tank or line by passing it through the entire circuit by using both pumps, all colours at the same time:

  • After the wash cycle, ACS empties the circuit with both pumps driving the solvent / dirty water to its corresponding tank or line.
  • For a perfect result, I-ACS repeats the cleaning cycle but with clean solvent (or water).
More effective and cleaner
The equipment works in better conditions
