Definitions

  • the object of the present invention is an ink re-use system for printing machines that incorporates appreciable innovations and advantages.
  • the invention is related to a system for the re-use of diluted ink coming from the cleaning processes for printing machines, in particular flexographic and rotogravure types of printing machines.
  • the flexographic and rotogravure printing machines are provided with automatic cleaning systems for the inking assemblies.
  • These systems allow the circulation of a solvent across the inking circuits that acts as a cleaning element that is then discharged into a common tank, in such a way that if the printing has eight colours, the liquid obtained from the cleaning of each one of the printing assemblies and which hereafter will be called diluted ink "DI", is going to end up in a common tank where a dark coloured "DI" is obtained due to the mix of the "DI" of differing colours, as can be seen in figure 1 .
  • this DI is subjected to a distillation process obtaining the solvent and the ink sludge which is then sent to a waste treatment company so as to be dealt with in an incineration process.
  • the printing machine has automatic viscosity control systems which, during the printing process, add solvent to the ink.
  • the present invention has been developed for the purpose of providing a DI ink re-use system that solves the above-mentioned disadvantages, in addition contributing other additional advantages that will become clear from the description that is given below.
  • an ink re-use system for printing machines wherein a plurality of individual tanks is provided for the differing colours, one tank with a clean cleaning agent, one tank for the collection of the dirty cleaning agent, and which is characterised in that it includes at least one additional tank for the collection of the ink that has been diluted and transferred, in such a way that it establishes a bi-directional relationship between at least one additional tank and one of the individual tanks filled with coloured ink.
  • a pipe that sends the diluted ink from the individual tank full of ink to the additional tank and a second pipe that sends the diluted ink from the additional tank to the individual tank full of ink.
  • said by-pass means that associates the additional tank to the diluted ink, the tank with the dirty cleaning agent and the tank full of ink for printing.
  • said by-pass device consists of an electro-valve governed by a PLC ("programmable logic controller").
  • system can be provided with some means of colour detection associated to the by-pass means in such a way that in line with the colour detected it sends a signal to the PLC to open or close the passage defined between the tank full of ink and the additional tank.
  • ink viscosity detection means associated to the by-pass means can be provided in such a way that depending on the viscosity level detected it sends a signal to the PLC to open or close the passage defined between the tank full of ink and the additional tank.
  • an embodiment of the ink re-use system for flexographic printing machines in accordance with the invention is provided with a plurality of individual tanks 1, 2, 3, 4, 5, 6, 7, 8 for differing colours, one tank with clean cleaning agent 9 connected by means of a circulation pipe 10 to one of the individual tanks 8, in this case corresponding to the tank that stores the white ink, a tank for the collection of the dirty cleaning agent 11 and a tank with the solvent 12 that can be any type of suitable solvent that is known in the art hence greater detail is not going to be entered into.
  • This system is in addition provided with a pipe 13 that sends the diluted ink from the individual tank full of white ink 8 to an additional tank 14 with the help of a pump 16 and a second pipe 15 that sends the diluted ink from the additional tank 14 to the individual tank full of ink 8 in such a way that it allows the re-use of the diluted ink that was previously treated in an earlier cleaning stage.
  • Tank 9 and tank 12 are connected to each other by means of a pipe 19 and is provided with an impulsion pump 20 in order to supply solvent to the clean cleaning agent when it is thus required.
