LASER ANILOX ROLLS CLEANING SYSTEM

The cleaning of anilox rolls has always been one of the biggest concerns of flexography printers. If they are not perfectly clean, the cylinders reduce their transfer capacity and therefore color intensity is lost in the printing, with the consequences for the production that this may have: invalid impressions, longer start-up times, etc.

I-LAC solves this problem effectively thanks to the laser that removes in depth the dry ink inside the cells without damaging the cells of the roll. A specially designed optical laser vaporizes any residue and cleans the remains of dry ink, adhesives, waxes, silicones, etc. The laser technology allows a cleaning without any mechanical or thermal action on the anilox cylinder, which allows us to clean even after each use and preserve the useful life of the anilox rollers for much longer.

Accurate and reliable laser technology

The new laser anilox cleaning system uses a fibre laser technology to emit a beam through a series of diodes mounted on an optical fibre. The cells of the anilox are completely clean, getting near of the nominal contribution, being able to clean any type of color, base of the ink or adhesive.

During the printing processes, the ink used is deposited at the bottom of the anilox cells and reduces the volume and, consequently, the roll contribution is reduced.
Through laser technology, the laser anilox cleaning system removes ink from the interior of the rolls’s cells, extracting any type of ink, glue or varnish. In this way, the initial volume of the cylinder is recovered 100%, being able to maintain the intensity of the color always constant.

Intuitive software

The laser anilox cleaning system is controlled by a user interface that allows simple and intuitive operation of the machine without the need for additional knowledge.

Easy configuration

Through the touch screen you can adjust the parameters of the anilox in addition to displaying the status of the cleaning at all times.

ALL THE ADVANTAGES FOR YOUR ANILOX CERAMIC ROLLERS

  • The fastest cleaning system on the market today with a decrease in cleaning time of up to 80% compared to other systems.
  • Able to clean very high line-count where other systems have no possibility.
  • Rolls with a maximum ink supply. The cells are clean and 100% of the intensity is maintained.
  • Being the maximum intensity, the times of repetitions of work are reduced.
  • Cleaning of any color and type of water-based ink, solvent base, adhesives, varnishes, hardeners, etc.
  • Does not damage the surface of the material or cause wear.
  • Does not generate increases in temperature on the cleaning surface.
  • Does not generate waste, does not require pneumatic air supply or requires water intake, it only requires electrical power.
  • The user interface allows easy operation of the machine without the need for technological knowledge.
  • Confirmity with international safety regulations.
  • Allows the cleaning of Anilox with or without shaft.

The system cleans the surface of the anilox rolls very efficiently using laser technology. The process is fast, simple, fully automatic and leaves the Anilox clean, achieving the cell volume at 100% without the use of chemical products, bicarbonates, etc. so that the machine only needs power and does not generate any kind of waste.
The cleaning is done with a special diode laser designed to eliminate foreign elements to the ceramic surface recorded as remains of the dry ink, adhesives, waxes and silicones that may be on the surface and inside the cells. All this without altering or damaging the surface.
It does not exert any mechanical action on the ceramic surface, the dirt expelled is captured by a filter after the ventilation system arranged in the equipment.

Electronic
The machine is controlled by a PLC and a touch screen, OMRON brand. The operator can easily enter the parameters and external measurements of the anilox and start the washing process. 

Operator interface
The touch screen besides to the configuration of the anilox, also allows to visualize the state of the machine in each moment, time to finish the cycle of the cleaning, list of current alarms or history of alarms, etc. The machine also has illuminated pushbuttons and an emergency stop for easy, quick and correct operation of the machine.

Laser
The machine has an innovative laser with diode technology that reduces maintenance to a single intervention every 100,000 hours (on average) of operation.

Extraction system
The machine uses an extraction system that allows the capture of all the particles in a reusable filter.

Servomotor
The OMRON servomotor allows positioning and linear movement (X movement) of the laser with high precision and reliability that allows all movements during the cycle automatically.

Rotation motor
The rotation motor allows the rotation of the anilox (Y movement) by means of a reducer, frequency variator and rubber coated rollers so as not to damage the surface of the anilox.

Door
The door of the machine allows easy access to it and is specially designed so that the operator can not access while the laser fires its beam. The door complies with all regulations and if the customer opens the door during the cycle, the machine will automatically go into standby mode until the operator closes it again. With the total door opening, it can be accessed by crane.

The washing process is fully automatic and consists of the following cleaning stages:

  • Preparation: The operator will inform roll diameter and width.
  • Cleaning: The machine will automatically position the laser unit (using a servomotor) and start the cleaning cycle (laser firing with horizontal movement, rotational rotation and extractor fan)
  • Completion: When the laser reaches the end of cleaning, it automatically returns to its starting position.

After the cycle, the operator must open the door and extract the anilox.

The maximum cleaning speed * for our laser is almost 6 cm2/sec. The approximate cleaning time for the a 1200 mm and 150Ø mm  roll is 20 minutes*.
*NOTE: Estimated times, may vary depending on the characteristics of the roll (line-count, volume and saturation of the cells) and the I-LAC equipment.

The cleaning machine includes all the elements and materials necessary for the start-up and good operation of the machine.
The customer should only prepare the area where the machine will be installed and the power supply.
