Definitions

  • the present invention refers to a system for the management and the distribution of flexographic ink for four-colour printing in process to install on printing systems.
  • the system in the following description, will be divided, for greater clarity, in three distinguished parts:
  • the system is made up a stainless steel containing tank devided in two buckets, wich can be installed in pit or at floor level, in which is inserted a welded frame fit to support the ink tanks. These tanks are mounted on 3 load compression sensor for electronic weighing, connected to a microprocessor digital indicator installed on the general switchboard panel, in order to indicate the actual ink level in the tanks. A signal light will indicate the lowest level, while a float will indicate the maximum level and will interrupt the feeding operations.
  • the system can be installed on whichever printing system improving the functional performances and reducing the pollution.
  • a pneumatic pump transfers the ink from the terminal reservoirs to the stocking ones.
  • Another disadvantage of the traditional systems is the use of the simple plastic connections of the ink reserviors, because this is not reliable and in many occasions it detaches with consequent flooding of the storage zone, environmental pollution, risk of operator falls from who could slip on the liquids poured on the floor.
  • Other disadvantage of remarkable importance in the traditional systems is the use of a great water amount for washing the inked parts, and the consequent water environment dispersion, as well a continuous utilization of new water for the mixing process and other washings at the end of the working cycle.
  • the aim of the present invention is to solve the disadvantages over indicated, supplying a system that:
  • the outline over showed represents in a simplified way a plant for the fitting out of the print ink.
  • the operator at the beginning of the production prepares the print ink by an electrical control device he adjusts the necessary amount of pure ink in the mixer. This amount is visualized net of what by chance remained from the previous preparation.
  • the system allows by means of an electro-hydraulic compensation a perfect dosage of the ink, obtaining the right dosage to the print without waste.
  • the system can be of several dimensions in order to equip printing machines of different sizes and types.
  • the water recovery system of the equipment always allows an easier employment, a lower economic waste of resources, less water pollution so as to permit an easier and safer use of the equipment, increasing its efficiency and competitivness.
