Easy job adjustment

Cingular Modules

Faster setpoints, less shrinkage, more benefits

The job changeovers in flexo printers generate waste in web and inks that have a significant impact in the profit and loss account. The current trend to reduce runs implies more changeovers, an increase in the total waste generated during the setpoints and a loss in machine efficiency.

At Comexi we have launched a set of solutions that adapt to the difference scenarios facing our clients. The CINGULAR MODULES offer automatic and semi-automatic features, with or without a mark, adapted to the specific requirements of our industry.

 

CINGULARDot2

  • Automatic printer unit pressures and register system.
  • Use of trademark.
  • Average waste generated throughout the 100 m process on one side and according to the repeat.
  • Inspection system with camera.

CINGULARPress2

  • Automatic printer unit pressure setpoint system.
  • Waste generated in the process between 20 and 160 m (with an average of 90 m) according to the repeat.
  • Suitable module for adding to the CReg semi-automatic register module without marks.

CINGULARReg

  • Semi-automatic register setpoint system for third party manufacturers.
  • Without specific marks.
  • Inspection system with camera.
  • The CINGULARPress2 module can be added to improve the automation.
Inking control

Excellence with the most efficient cleaning system

The Comexi SelfCleaning is an automatic system that manages the ink supply to the print, and cleans the ink chamber, the anilox, ink tanks and connection hoses in the circuit.

The system adapts to water-based inks and solvent-based inks.

Its high level of automation makes it possible to program different cycles (from light to intensive) to adapt solvent and time consumption to your needs. These advantages combined with the easy use thanks to the simple interface, complete a system designed according to the highest standards of efficiency.

  

MAIN BENEFITS FOR YOU

INTEGRATION AND ERGONOMICS

The SelfCleaning is built into the actual machine frame. Its ergonomic arrangement provides for easy operator access and facilitates the maintenance tasks for all elements.

The system includes tanks for the solvent that connect to solvent recovery equipment, achieving safe and fully automatic operation.

 

CONTROL OVER THE INK

It includes built-in online viscometers to automatically regulate the viscosity in the values set up as optimum for printing. An upgrade of the standard version also includes a temperature regulating system in order to maintain the ink working temperature.

The new electronic control allows continuous control over the working and performance of the various valves, saving large amounts of ink and reducing costs.

 

MACHINE SCREEN CONTROLS

Visualising the system parameters via the PLC allows you to control the process from start to finish. The impulse and time screens provide preventive maintenance, minimising the machine stops as well as achieving the system's best setpoint.

 

BETTER PERFORMANCE AND LESS MAINTENANCE

The pneumatic pumps controlled by the PLC manage the ink induction and suction, at the same time as adapting the frequency to the print needs prolongs the life of the membranes.

 

Easy access to the printing units
Easy access to the printing units

The press has 8 decks adapted for a front print. Its design adapts to the easy access requirements for maintenance and daily operation thanks to the  FLEXOEfficiency concept.

High performance doctor blades
 High performance doctor blades

The doctor blade is assembled in a closed swinging chamber mounted on linear guides, with automatic horizontal movement by means of low friction, pneumatic pistons.

It is dismantled easily without having to disconnect the inking tubes, facilitating the cleaning and changeover tasks, with simple handling thanks to its extraordinary 12 kg weight.

Thanks to the patented ComexiMAGNETBlade technology, a tool-free magnetic changeover system, we can obtain a fast and safe blade and seal changeover.

Fast sleeve changeover

The plate cylinder and anilox sleeve changeover takes a couple of minutes. The covers are opened manually, in a quick, simple way.

Drying: Power and accessibility
Drying: Power and accessibility

The drying equipment is made up of two circuits connected together by hot air blown at high speed, which evaporates the solvent contained in the ink. The system is designed to comply with the speed requirements that the market calls for.

For any maintenance needs, you can access the drying area through platforms specially designed for this purpose, and also the tunnel through sliding doors located at the lower part of the drying module.

Access to the top area

The press is designed so that it is possible to access all the maintenance and cleaning points from the platform located on the printing unit, avoiding maintenance work at a height using a ladder. The job can be done from platforms designed according to the most demanding safety standards.

Easy maintenance

You will find several details that highlight this machine as the best solution in terms of maintenance: its easy handling and doctor blade access, filter change, greasing points, decentralised electronic panel, and others.

Electronics and perfectly adapted interfaces

The press is designed so that most of the functions can be controlled from the control console. In parallel our COMPACT concept, based on the SIMOTION platform and in decentralising the electronics, provides for high electronic integration, thereby eliminating electronic equipment containers and facilitating maintenance tasks.

At Comexi we apply the DDDrive concept for driving the shafts via AC motors without any kind of mechanical transmission, controlled by absolute encoders coupled directly to the shafts. All improving the register and quality of the print.

You will obtain production data for subsequent analysis such as the amount of meters printed, the amount of meters lost, the job duration time, stop times, print times, average real speed, etc. 

With the operator attributing the cause of the stop, statistics are obtained on the various causes of stops and the time assigned to each one. All the data can be stored in the computer memory and/or on disks.

Work files can be created to increase the efficiency in the job changeovers, and these files can be recovered subsequently.

Energy efficiency

The ENERGYSavvy concept, applied to a set of electrical and electronic control technologies, saves large amounts of energy and drastically reduces CO2 emissions.
