Definitions

  • the present invention refers to a device and method for deposition of fluids, for reproducing designs or decorations onto a surface, particularly the surface of objects, by means of fluids spraying, ejection or deposition, in particular fluids containing high concentration of solids, and it is one object thereof to solve the problems that object decorations currently have, especially ceramic products such as stabs or tiles and/or glass, problems which can also be extended to other fields of application of dispersions having a high solid content according to a determined pattern, design or motif.
  • thermal devices from Thermal Ink Jet
  • valves actuated by valves
  • piezoelectric actuators such that droplets are only generated when they are intended to be injected onto the object or substrate.
  • the droplet size can be very small (lower than 80 picolitres, compared to the 600 picolitres of the CIJ technology), the place where the droplets are deposited is perfectly controlled and the distance between the printheads for the different inks is reduced to few centimetres. All that makes the printing quality optimum and it also makes it possible to work readily with four-colour process (CYMK).
  • the CIJ technology is used, above all, for product and container marking and coding, and in this technology a pump conducts the fluid from a deposit to the small nozzles ejecting a continuous stream of droplets at a high frequency (in the range of about 50 kHz to 175 kHz), by the action of a piezoelectric glass which vibrates, thus pressing the walls of the supply channel, and the droplets are subjected to an electrostatic field which provides them of a charge, then the charged droplet goes through a deflection field that determines, based on the intensity of the electric field applied, if the droplets are directed to different points in the substrate or otherwise recirculated.
  • a pump conducts the fluid from a deposit to the small nozzles ejecting a continuous stream of droplets at a high frequency (in the range of about 50 kHz to 175 kHz), by the action of a piezoelectric glass which vibrates, thus pressing the walls of the supply channel, and the droplets are subjected to an
  • the high droplet frequency of the CIJ is directly reflected in the high speed printing capacity, as it is evidenced by applications such as the date coding on beverage cans.
  • An additional advantage of CIJ is the ejection speed (about 25 m/s) allowing (as compared to other ink injection technologies) relatively large distances between the printhead and the substrate, which is useful in industrial environments.
  • the CIJ has been provided with an advantage over other ink injection technologies in its capacity for using inks based on volatile solvents, which allows for a quick drying which helps the adherence onto many substrates.
  • the TIJ technology (also known as Bubble-Jet), is based on the sudden evaporation of small amounts of ink (micro-explosion), causing a bubble, which pushes the ink out of the printhead, forming the corresponding droplet that is deposited onto the substrate to be printed.
  • the main application is in home printers, due to the low productivity that can be reached and to the fact that the printheads or injectors are not so robust for industrial applications.
  • Thermal printheads must be changed periodically, since the repetitive heating cycles required for the thermal inkjet printing causes the electronic system operation of the printheads to deteriorate.
  • the piezoelectric technology (usually known as Piezoelectric Pressure Wave) is based on the application of an electric current to a piezoelectric device which, upon deformation, generates a pressure wave (by sudden reduction of the ejection chamber volume) producing ejection of the droplets of ink that are sprayed onto the substrate.
  • the production reached is very high, with the printheads being reliable for continuous operation for long periods of time, thereby this is the technology that has been implemented for industrial applications.
  • piezoelectric deposition devices which are based on the way the actuator is deformed [ Alex Grishin, Piezoelectric shear mode drop-on-demand inkjet actuator, Sensors and Actuators A 101 (2002), 371-382 ] and therefore on the way the pressure wave is created, with the compression (squeeze mode actuator), bent (bend mode actuator), piston (push mode inkjet actuator) and shear ones (shear mode actuator) being mostly used.
  • DOD technology allows obtaining solutions for fluid ejection or deposition with a small droplet size (lower than 80 picolitres, compared to the 600 picolitres of the CIJ technology), featuring high resolution and for fluids having very low viscosity at the ejection temperature.
  • deposition devices being currently on the market, feature an additional insuperable drawback.
  • Another additional technical problem is the non-scalability of many of the current solutions, since the ejection of droplets with a size higher than 1,000 picolitres, involves high volume ejection chambers, wherein the generation of a pressure wave with the current methods technically and/or economically unfeasible.
  • deposition devices have been previously suggested featuring deposition by ejection through mechanically shuttered nozzles, operating over a pressure circuit of the fluid to be deposited, involving multiple scaling, resolution, mechanical complexity and viability drawbacks, which make them unsuitable for solving the technical problem stated.
  • WO 2013/013983 discloses a device in which, by the action of a plunger (of about 3 and 5 mm diameter, claim 14), from certain means placed outside the supply channel, shuttering of the ejection orifice is produced, being the supply channel pressurized at a pressure lower than the atmospheric pressure.
  • Said invention has the drawback of providing low resolution and high technical complexity regarding the sealing of the aforementioned plungers, with respect to the supply chamber, the existence of springs, the mechanical fatigue and time of response of which can seriously constraint the reliability of the device operating at 1kH as it is claimed, and the use of electromagnetic means for operation thereof, adding further complexity factors because of its volume, thus, according to the description, drawings and claims, it seems clear that it is not able to achieve a resolution higher than 1/3.3 points per centimetre.
  • WO 2010/146473 discloses a printhead being particularly suitable for viscous or particle-containing fluids, having multiple channels, the operation of said device being controlled by means of a micro-electro-pneumatic circuit containing a micro-valve 18 and a regulating pneumatic throttle 23, so as to generate a control pressure Pc actuating a diaphragm 8 actuated by the control pressure Pc, thus controlling fluid discharge through the fluid outlet 6.
  • said invention provides a version of a device being pneumatically controlled which is analogous to one of the "piezo bend mode" technology, using a diaphragm, having the advantage that the pressure created in the chamber is higher than that being reached with a piezoelectric actuator, but it does not solve the problem of the mechanical resistance of said membrane at high pressures and frequencies, which are necessary for the ejection and the solution of the technical problem.
  • US 2002/0191053 describes, in the first claim, a fluid dispensing apparatus for selectively dispensing desired quantities of a fluid under pressure, said apparatus comprising a base plate having a dispensing passage extending about a first axis, a valve arrangement associated with said dispensing passage, and a piezoelectric transducer acting on said valve arrangement to effect displacement of said valve arrangement between a first position in which said dispensing passage is closed and a second position in which said dispensing passage is connected to a source of said fluid under pressure, wherein said valve arrangement comprises a slide valve, said slide valve and said piezoelectric transducer being arranged such that during, at least, the initial displacement of the valve arrangement from said second position towards said first position, said slide valve being displaced in a direction transverse to said first axis.
  • Patents US 2009/0115816 and US 2005/084952 similarly claim an ink jet printing element comprising a pressurized ink chamber, at least one ink nozzle that is closed by a mobile valve body, and a piezoelectric valve actuating element which performs bending motions, in a reciprocating motion, and that is electrically connected to a control device.
  • the spring strip is bent in such a way that an end pulls from the valve side (LLA) extending transversely to the reciprocating motion of the valve (6), and a longitudinal section of the strip is perpendicular thereto.
  • the end of the valve side attaches in a way it is allowed to move, to the valve body through a traction rod or through a wire having an adjusting nut.
  • Said devices are characterized in that they feature an indirect action of the actuator over the closure or valve, the position of which has to be secured by a spring, and the connection between the traction rod or the wire and the exterior feature additional sealing and abrasion problems, particularly when used for liquids with high solid content.
  • patent US 4,450,375 refers to a bending typology piezoceramic element or bender which cooperates with an impacting element, membrane and valve seat to provide a novel piezoelectric transducer arrangement for achieving desired rapid and accurate control of fluids under pressure in a variety of different applications, such as, computer printing, fluidics, etc.
  • the piezoelectric element is isolated from the fluid being used.
  • US 4,629,926 also refers to a flow control device of the same type, wherein piezoelectric spring-like benders are operably associated with impacting members, each capable of deforming a membrane so as to control flow past a valve seat upon change in the electrical condition of the piezoelectric members.
  • Each bender and impacting member is isolated from the fluid by the membrane.
  • the benders may be mounted individually, arranged side-by-side for multiple uses or can be grouped in a comb-like configuration. A mounting is provided for the benders, which permits the force exerted on the impacting member by the free end of the bender to be adjusted, and keeps the electrical isolation of the benders one from the others.
  • the mounting as installed provides an adjustable supporting point and a clamping member cooperating with the support for fixing the adjustment.
  • the mounting keeps the free end of the bender centred over the impacting member, and enables initial deflection adjustment and further provides electrical connection of the benders with a fixed receptacle. Where required, any differences in thickness between the assembled benders and the receptacle can be corrected.
  • US 4,629,926 and US 4,450,375 do not solve the technical problem of working with very viscous fluids, having a high solid content, since the use of a deformable membrane and a deforming means being interposed (by impact with the bender), introduces a higher stress load for the actuator, particularly for operation at high frequency, furthermore, the high distance between the printheads of the different inks due to the actuators arrangement and size, makes it practically impossible to use due to the distance between the printheads for the different inks, when resolutions higher to the native one are intended.
  • the present invention describes a method, device and machine for fluid deposition, particularly solid dispersions in fluids, having high solid contents and high viscosity, such that the problems related to the application thereof, in an efficient and cost-effective manner, may be solved.
  • the present invention describes a fluid deposition, injection or spraying method, in particular solid dispersions in fluids, and more preferably solid dispersions in liquids, by recirculation of said fluid in a device chamber under pressure, such that the side wall of said device communicates, by means of a orifice drilled therein, with a spraying channel arranged on an adjacent wall and being communicated with said orifice, such that, upon the action of a shutter, being individually operated for each orifice arranged over an actuator, the activation of this actuator arranged in the spraying direction, causes the shutter to slide in a perpendicular direction, detaching from the orifice and releasing the communication path of the pressurized chamber with the ejection channel.
  • Said method for the elements deposition allows, due to the vertical situation of the actuators (that is, in the ejection direction), a reduced dimension in the (x) direction in which the ejection nozzles extend (that is, printing width), keeping a constant separation from each other (native resolution) and a reduced size in the (y) direction, perpendicular to this (x) direction of the printing width (w i ) and to the ejection direction (z), which allows a reduced spacing between devices, a reduced size thereof and thus an efficient way of working with fluids.
  • figures 10 and 12 show the bending experimented by the piezoelectric actuator, after it being applied a determined electric charge onto the electrodes thereof, releasing the passage orifice, by the individualized and controlled action if the control means (7).
