Definitions

  • This invention relates to ejecting drops.
  • Ink jet printers are one type of apparatus for depositing drops on a substrate.
  • Ink jet printers typically include an ink path from an ink supply to a nozzle path. The nozzle path terminates in a nozzle opening from which ink drops are ejected.
  • Ink drop ejection is typically controlled by pressurizing ink in the ink path with an actuator, which may be, for example, a piezoelectric deflector, a thermal bubble jet generator, or an electrostatically deflected element.
  • An actuator which may be, for example, a piezoelectric deflector, a thermal bubble jet generator, or an electrostatically deflected element.
  • a typical print assembly has an array of ink paths with corresponding nozzle openings and associated actuators. Drop ejection from each nozzle opening can be independently controlled.
  • each actuator is fired to selectively eject a drop at a specific pixel location of an image as the print assembly and a printing substrate are moved relative to one another.
  • the nozzle openings typically have a diameter of 50 microns or less, e.g. around 25 microns, are separated at a pitch of 100-300 nozzles/inch, have a resolution of 100 to 3000 dpi or more, and provide drops with a volume of about 1 to 120 picoliters (pL) or less.
  • Drop ejection frequency is typically 10 kHz or more.
  • Hoisington et al. U.S. Patent No. 5,265,315 describes a print assembly that has a semiconductor body and a piezoelectric actuator.
  • the body is made of silicon, which is etched to define ink chambers. Nozzle openings are defined by a separate nozzle plate, which is attached to the silicon body.
  • the piezoelectric actuator has a layer of piezoelectric material, which changes geometry, or bends, in response to an applied voltage. The bending of the piezoelectric layer pressurizes ink in a pumping chamber located along the ink path.
  • Piezoelectric ink jet print assemblies are also described in Fishbeck et al. U.S. Patent No. 4,825,227 , Hine U.S. Patent No. 4,937,598 , Moynihan et al. U.S. Patent No. 5,659,346 and Hoisington U.S. Patent No. 5,757,391 , the entire contents of which are hereby incorporated by reference.
  • GB-A-2339170 discloses a drop ejection device according to the preamble of claim 1.
  • the invention features a drop ejection device according to claim 1
  • the invention features a method of ejecting fluid according to claim 16.
  • Embodiments may include one or more of the following advantages.
  • Printing errors can be reduced by controlling waste ink that collects adjacent ejection nozzles, where it could interfere with ink ejection, or become disposed on the substrate and obscure an image.
  • the waste ink can be controlled by directing and containing it in controlled locations by using vacuum, capillary forces, gravity and/or surface tension effects.
  • the waste ink can be recycled to an ink supply, or directed to a waste container off the nozzle plate surface.
  • the waste control aperture features can be formed accurately on a nozzle plate by, e.g., etching a semiconductor material such as a silicon material.
  • an ink jet apparatus 10 includes a reservoir 11 containing a supply of ink 12 and a passage 13 leading from the reservoir 11 to a pressure chamber 14.
  • An actuator 15, e.g., a piezoelectric transducer covers the pressure chamber 14.
  • the actuator is operable to force ink from the pressure chamber 14 through a passage 16 leading to a nozzle opening 17 in an nozzle plate 18, causing a drop of ink 19 to be ejected from the nozzle 17 toward a substrate 20.
  • the ink jet apparatus 10 and the substrate 20 can be moved relative to one another.
  • the substrate can be a continuous web that is moved between rolls 22 and 23.
  • the inkjet apparatus also controls the operating pressure at the ink meniscus proximate the nozzle openings when the system is not ejecting drops.
  • pressure control is provided by a vacuum source 30 such as a mechanical pump that applies a vacuum to the headspace 9 over the ink 12 in the reservoir 11.
  • the vacuum is communicated through the ink to the nozzle opening 17 to prevent ink from weeping through the nozzle opening by force of gravity.
  • a controller 31 e.g. a computer controller, monitors the vacuum over the ink in the reservoir 11 and adjusts the source 30 to maintain a desired vacuum in the reservoir.
  • a vacuum source is provided by arranging the ink reservoir below the nozzle openings to create a vacuum proximate the nozzle openings.
  • An ink level monitor (not shown) detects the level of ink, which falls as ink is consumed during a printing operation and thus increases the vacuum at the nozzles.
  • a controller monitors the ink level and refills the reservoir from a bulk container when ink falls below a desired level to maintain vacuum within a desired operation range.
  • the ink in which the reservoir is located far enough below the nozzles that the vacuum of the meniscus overcomes the capillary force in the nozzle, the ink can be pressurized to maintain a meniscus proximate the nozzle openings. Variations in meniscus can cause variations in drop velocity and can lead to air injection or weeping.
  • the operating vacuum maintained at the meniscus is about 0.5 to about 10 inwg, e.g., about 2 to about 6 inwg.
  • nozzle 17, having a nozzle width, W N is surrounded by waste ink control apertures 32, having an aperture width, W A .
  • the apertures generally surround the nozzle and are spaced a distance, S, from the periphery of the nozzle.
  • the apertures communicate through a lumen 34 and an opening 36 with an ink passage upstream of the nozzle opening.
  • ink may collect on the nozzle plate. Over time, ink can form puddles which cause printing errors. For example, puddles near the edge of a nozzle opening can effect the trajectory, velocity or volume of the ejected drops.
  • the apertures 32 provide a region in which waste ink can collect to avoid forming excessive puddles. Ink can be drawn into the apertures 32 by capillary force and/or by vacuum produced by the piezoelectric actuator 15 and/or the vacuum source 30.
  • FIG. 3 the operation of the ink control apertures during drop ejection is illustrated.
  • the nozzle 17 is illustrated in a non-jetting condition in which an ink meniscus 24 forms in nozzle 17.
  • ink is directed out of the nozzle opening 17 and a drop 19 is formed and ejected.
  • ink may also protrude from apertures 32, but it is not ejected from the apertures.
  • waste ink 38 may be deposited onto nozzle plate 18.
  • waste ink can be disposed on the nozzle plate as the drop separates from the ink or back-splashes in flight or satellites drops can be directed back to the nozzle plate.
  • the meniscus 24 is withdrawn by a vacuum.
  • the vacuum may be created the vacuum source 30 and/or by the piezoelectric actuator as it is actuated from a pressurizing condition, in which the actuator pressurizes ink 12 in chamber 14 to eject a drop, to a neutral or negative condition in preparation for the next drop ejection.
  • the vacuum on nozzle 17 is also communicated to ink control openings 32 so that waste ink is drawn into the openings 32 and through lumens 34 in a direction indicated by arrows 35.
  • waste ink does not pool excessively on the nozzle plate.
  • the nozzle plate, particularly the region 33 between the nozzle opening and the aperture includes a nonwetting coating, e.g. a polymer such as a fluoropolymer (e.g. TEFLON) to prevent forming of puddles of ink stably in this region and to encourage waste ink flow into the aperture.
  • the vacuum can also be produced by controlling the vacuum over the ink reservoir 11.
  • a relatively wettable nozzle plate surface can be provided between the nozzle and the apertures and a nonwetting coating can terminate outside the circle of apertures to discourage ink flow beyond the apertures.
  • the size, number, spacing and pattern of the apertures are selected to prevent excessive waste ink pooling.
  • the size and number of apertures can be selected to prevent ejection of ink from the apertures while drawing a desired amount of waste ink without requiring large additional jetting forces for drop ejection.
  • the apertures have a flow resistance sufficiently greater than the nozzle opening to prevent ink ejection from the apertures during drop ejection.
  • the resistance of each aperture is about 25 times or more, e.g. 100 times or 200 times or more than the resistance of the nozzle.
  • the total resistance of all the actuators is selected to withdraw a desired volume of waste ink without needing to significantly increase actuator displacement.
  • the increase in actuator deflection can be estimated by comparing the average flow through the apertures with the nozzle flow.
  • the average flow through the apertures is about 10% or less, e.g. 5% or 2% or less of the flow through the nozzle.
  • the apertures are arranged to draw, 5%, 1%, 0.5%, 0.1% or less of the ink jetted.
  • l c is the length of the channel
  • r c is the radius
  • ⁇ is the fluid viscosity
  • R c is the resistance.
  • the average flow through a channel is obtained by dividing the average pressure by this resistance.
  • a system including twelve 3 micron apertures, each of which corresponds to 20% of the nozzle width, would have the following features. Because fluidic resistance varies inversely with the fourth power of diameter, apertures that have 20% of the nozzle diameter have 625 times the resistance. Twelve apertures surrounding the nozzle have a total resistance that is 52 times the resistance of the nozzle. The average flow through the apertures will be about 1/52, or 2% of the flow through the nozzle. For a piezoelectric actuator, actuation voltage, which causes the actuator displacement, increases by about 2%.
  • Twelve 3 micron radius apertures that have a 30 micron long lumen can draw 636 pL of a 10 cps ink with a 2 inch water vacuum created at the ink reservoir. This accommodates jetting 10 pL drops at 63.6 kHz, capturing 0.1 % of the ink.
  • the vacuum at the apertures can increase substantially due to the actuator displacement during the fill stage of jetting in which the vacuum is created by the actuator as well as the vacuum in the reservoir.
  • the apertures are provided in a pattern that surrounds the nozzle opening.
  • the apertures are spaced a distance, S, so that fluid does not collect adjacent the nozzle opening where it would influence drop ejection.
  • the apertures are spaced closely adjacent the nozzle periphery.
  • spacing is about 200 % or less, e.g., 50% or less, e.g. 20% or less of the nozzle width.
  • apertures are positioned at greater spacing from the nozzle periphery, e.g., 200 % to 1000 % or more of the nozzle diameter.
  • the apertures can be provided at various spacings, including closely spaced apertures and apertures of greater spacing. In embodiments, there are three or more apertures associated with each nozzle.
  • the apertures have a width of about 30% or less, e.g. 20% or less or 5% or less than the nozzle width.
  • the vacuum on the apertures during fluid withdrawal is about 0.5 to 10 inwg or more.
  • the nozzle width is about 200 micron or less, e.g. 10 to 50 micron.
  • the ink or other jetting fluid has a viscosity of about 1 to 40 cps.
  • Multiple nozzles are provided in a nozzle plate at a pitch of about 25 nozzles/inch or more, e.g. 100-300 nozzles/inch.
  • the drop volume is about 1 to 70 pL.
  • a system can be operated to continuously direct ink into the control apertures 32 when not ejecting drops to avoid ink stagnation or ink drying in the apertures 32.
  • the actuator 15 is controlled to cause an ink bolus 27 to extend from the nozzle 17, but without sufficient energy to eject a drop.
  • the bolus 27 retracts into the nozzle and some of the ink spreads onto the surface of nozzle plate 18.
  • the actuator 15 is then operated to create a vacuum on the nozzle 17 and control apertures 32.
  • the ink on the nozzle plate is drawn into the control apertures 32.
  • control apertures 40 are in communication with a vacuum source that is isolated from the ink supply.
  • apertures 40 are in communication with a channel 42 that leads to a vacuum source such as a mechanical vacuum apparatus (not shown) that intermittently or continuously creates a vacuum.
  • a vacuum source such as a mechanical vacuum apparatus (not shown) that intermittently or continuously creates a vacuum.
  • the vacuum draws waste ink from the nozzle plate (arrows 46).
  • the ink drawn from the nozzle plate can be recycled to an ink supply or directed to a waste container.
  • the apertures can have non-circular cross-sections.
  • the apertures can be oval-shaped with the major axis of the oval aligned with the radius of the nozzle opening.
  • control apertures 50 include an absorbent material 52 to encourage waste ink 38 flow by wicking or capillary action.
  • the absorbent material 52 can be disposed in a channel 54 which leads to a bulk container of ink (not shown).
  • the material 52 can protrude slightly above the surface of the nozzle plate 18.
  • Suitable wicking materials include polymeric foams, e.g., a polyurethane foam, or other porous material.
  • the polyurethane precursor material can be delivered to the apertures as a low viscosity fluid which polymerizes in- situ within the apertures, forming the wicking material.
  • the apertures and/or the nozzle opening in any of the above described embodiments can be formed by machining, laser ablation, or chemical or plasma etching.
  • the apertures can also be formed by molding, e.g., injection molding.
  • the apertures and nozzle opening can be formed in a common body or in separate bodies that are assembled.
  • the nozzle opening can be formed in a body that defines other components of an ink flow path, e.g. a pumping chamber and the aperture can be formed in a separate body which is assembled to the body defining the nozzle opening.
  • the apertures, nozzle opening, and pressure chamber are formed in a common body.
  • the body can be a metal, carbon or an etchable material such as silicon material, e.g., silicon, silicon dioxide, a silicon nitride, or other etchable materials.
  • silicon material e.g., silicon, silicon dioxide, a silicon nitride, or other etchable materials.
