Definitions

  • This invention relates to inkjet printers and, more particularly, to an ink filtration arrangement in a continuous inkjet (CIJ) printer.
  • CIJ continuous inkjet
  • Ink or solvent make-up is typically supplied to inkjet printing systems through the use of disposable ink bottles.
  • An ink bottle may be mounted on an ink reservoir that includes a mating feature that allows ink to pass from the ink bottle into the ink reservoir.
  • Each ink bottle retains a finite amount of ink, typically a pint or litre of ink.
  • the properties of the printing ink may deteriorate over time. How long this may take depends upon a number of factors such as the rate at which new ink and/or make-up is added, the environment and the ingredients from which the ink is made.
  • the main ink filter is separate from the ink reservoir and is connected into the ink system by flexible tubing. This arrangement presents a cluttered appearance and the end connections on the tubes are a potential source of leakage.
  • the invention provides an ink service module for a continuous inkjet printer, said module having an ink reservoir and a filter, said module being characterised in that said filter is positioned in an enclosure within said module said enclosure being sealed from said ink reservoir and having connections to an exterior of said module.
  • said enclosure is located within said ink reservoir.
  • said ink reservoir and said enclosure are sealed within said module
  • said module further includes an array of connectors on a common exterior wall thereof, some of said connectors being in communication with said enclosure and some of said connectors being in communication with said ink reservoir.
  • the invention provides a continuous inkjet printer including an ink circulation system and an ink service module, said ink service module having an ink reservoir, a filter, and a plurality of connections to enable connection of said module to said ink circulation system, said printer being characterised in that said filter is positioned in an enclosure within said module, a first set of said connections communicating said enclosure with said ink circulating system and a second set of said connections communicating said ink reservoir with said ink circulating system.
  • connections are arranged on a common side of said module.
  • Figure 1 shows an isometric view, from the rear, of an ink service module according to the invention
  • Figure 2 shows a sectional view of the module shown in Figure 1 ;
  • Figure 3 shows the module assembled on to an ink circulation system
  • the invention provides an ink service module 5 for attachment to the ink circulation system 6 of a continuous inkjet printer. To this end a line of spigot connectors 7 are provided along one side of the module 5, the connectors 7 engaging in corresponding sockets (not shown) in the ink circulation system. Located in the top of the module 5 is a further connection socket 8 whereby an ink cartridge (not shown) may be mounted on the module 5 to replace ink from the module which is consumed through printing.
  • a solvent make-up module 9 may be similarly mounted to the ink circulation system 6.
  • the ink service module 5 has an ink reservoir 10 and a filter 11, the filter being located in an enclosure 12 which is within, but sealed from, the ink reservoir and communicates with the exterior of the module.
  • the filter enclosure 12 in use, will be subject to full system pressure of about 5 bar while the ink reservoir is at ambient pressure.
  • the module 5 is a fully sealed item. At the specified service interval, the module including filter(s) and any ink therein, is removed from the ink circulation system 6 and discarded.
  • the filter enclosure 12 communicates with the ink circulation system via a first set of two spigots 7b and 7c. The remaining spigots convey ink, including ink to and from the ink reservoir 12, at lower pressures. Because of the unique manner of isolating and mounting the filter 11 within the service module, longer life components such as the circulating pump may be included externally and thus not be subject to replacement at the same time as the service module. This significantly reduces servicing costs.
  • the invention provides a replaceable ink module that satisfies the requirement to provide service items such as replacement ink and filters in a single unit, whilst providing for different working pressures to be realised in the module when in use, and not including expensive items such as pumps.

Abstract

L'invention concerne un module de traitement d'encre ayant à la fois un réservoir d'encre et un boîtier de filtre. Le boîtier de filtre peut être situé à l'intérieur du réservoir d'encre mais de manière scellée par rapport à celui-ci, pour permettre au filtre de fonctionner à la pression du système tandis que le réservoir d'encre est à la pression ambiante.
