Definitions

  • the invention relates to ink jet recording systems, and more particularly to ink jet recording systems wherein ink is contained in a chamber or reservoir and is discharged through a nozzle orifice and adheres onto the surface of a recording medium.
  • heating elements may be provided to raise the temperature of the ink.
  • U.S. Patent 4,184,169, issued January 15, 1980 to Taylor et al a drop-on-demand ink drop printer is shown including two ink reservoirs having associated heating elements. The heating elements are used to create expanded vapour pressure to force the ink from one reservoir through a printhead and into the second reservoir.
  • heating elements are located along the flow path of ink in a printer to expand and vaporize the liquid ink to produce a pressure used to expel the ink.
  • U.S. Patent 3,878,519 issued April 15, 1975 to Eaton, an ink jet system is described wherein heat is applied to a stream of ink. The temperature change causes a change in surface tension of the ink, which controls the breakup of the stream into discrete droplets.
  • U.S. Patent 3,655,379, issued April 11, 1972 to Gundlach, is an example of a system which uses heat energy to produce vapour expansion pressure to propel ink from a drum surface onto a paper.
  • the aforesaid prior art is distinct from the present invention in that the present invention is directed to a wax-based hot-melt ink for an ink jet system incorporating heating elements to cause a liquid-solid phase transition of the ink.
  • An object of the present invention is to provide a liquid jet recording system employing ink which undergoes a liquid-solid phase transition.
  • Another object of the present invention is to provide an ink jet recording system using a wax-based hot-melt ink.
  • a further object of the present invention is to provide an ink jet recording system incorporating heating elements, a hot-melt ink, and a piezoelectric element for emitting the ink.
  • a still further object of the present invention is to provide an ink jet recording system wherein the spreading of liquid ink onto the outside surface of the ink nozzle, is prevented.
  • Another object of the present invention is to provide a hot-melt ink for an ink jet recording system which avoids long drying times and is therefore useful for high speed.
  • Still another object of the present invention is to provide a hot-melt ink for an ink jet recording system which is in a solid state when the system is idle.
  • the invention provides ⁇ ink jet recording system comprising a reservoir for holding a supply of ink, a nozzle mounted in said reservoir for permitting ink to exit from said reservoir, an actuating element connected to said nozzle and to a source of electrical excitation signals for causing droplets of ink to be expelled from said reservoir through said nozzle, a quantity of ink disposed in said reservoir, said ink being composed in part of a meltable wax-base which undergoes a liquid to solid phase transition, and heating means associated with said reservoir to melt said ink into said liquid phase for explusion from said nozzle.
  • the invention includes a method of recording data comprising storing in a reservoir an ink having a meltable wax-base which undergoes a thermally reversible liquid to solid phase transition, effecting a solid to liquid or a liquid to lower viscosity liquid transition of the ink in the reservoir by heating the ink, and ejecting a drop of the heated liquid ink from a nozzle connected to the reservoir.
  • Figure 1 is a perspective view of an embodiment of an apparatus for retaining and selectively expelling ink according to the principles of the present invention. It is understood that a plurality of such ink drop emitters could be integrated to form an array.
  • FIG. 1 an illustration of an apparatus for providing drop-on-demand ink from a reservoir wherein the ink contained in the reservoir is a wax-based hot-melt ink which undergoes a liquid-solid phase transition.
  • the apparatus includes an ink reservoir 10, a nozzle 12, and a piezoelectric transducer 14 connected to a source of electrical pulses to provide excitation to cause droplets of ink to be moved from reservoir 10 and out through nozzle 12.
  • the particular configuration of reservoir 10, nozzle 12 and piezoelectric transducer 14 is not critical, and many variations of such combinations are known in the art.
  • a plurality of ink channels can be used in serial or line printing applications.
  • a piezoelectric transducer is used to provide the piston-like action.
  • a piezoelectric transducer is a device that converts electrical energy into mechanical energy. It can also do the converse.
  • U.S. Patent 2,512,743 to C. W. Hansell, issued June 27, 1950 an ink jet was described in which a circular piezoelectric transducer was used in an extensional mode, the extension being along the axis to drive ink.
  • the piezoelectric transducer was arranged coaxially with a conical nozzle, the axial extension being used to create pressure waves causing expulsion of droplets from the nozzle.
  • Several other transducer arrangements have been proposed.
  • Patent 3,946,398, issued March 23, 1976 shows a similar device; however, as disclosed in that patent the center deflection of the disk is used to eject ink through an orifice, the axis of drop ejection being perpendicular to the axis of the disk.
  • the apparatus of FIG. 1 further includes heaters 16 which are employed to impart thermal energy to a unique wax-based ink which is located in reservoir 10 and is passed through nozzle 12.
  • the heaters 16 may be as heating elements on a thin film which is incorporated on the reservoir 10 and nozzle 12.
  • a heating element is explained in the previously mentioned U.S. Patent 4,251,824 wherein Si0 2 is sputtered as a base layer onto an Al 2 O 3 base plate, followed by lamination of ZrB 2 as the heat generating layer and Al as the electrode, after which the heat generating body is formed by a selective photo-etching, and finally Si0 2 is again sputtered as an insulative protective layer.
  • Other heater embodiments are also available and may be employed in the present invention.
  • the meltable wax-based ink which undergoes a liquid-to-solid phase transition employed in the embodiment of the present invention is specified as having a phase transition temperature within a 60° centigrade to 80° centigrade degree range and a kinematic viscosity between one and forty centistokes.
  • a suitable ink according to the present invention would be composed of 95% paraffine plus 5% carnauba wax which has a viscosity of 14.7 centistokes at 65° centigrade.
  • wax-based ink in the present invention provides an advantage relative to the problem of nozzle face wetting.
  • Water-based inks produce wetting of the nozzle face, and spreading of the ink occurs onto the outside surface of the nozzle which is generally exposed to ambient air. This wetting results in impaired drop ejection.
  • the nozzle face is hydrophobic and that the properties of the hot-melt ink keep the ink from spreading on the nozzle face.
  • the hot-melt ink requires some warm up time, but the fact that the hot-melt ink is initially in a solid state has advantages, such as the virtual absence of evaporation when the printer is not active.
  • the ink may be in a semi-liquid state and be brought to a proper flowable liquid state only when printing is to be effected.
