Definitions

  • the present invention relates to ink delivery apparatus and systems, including ink delivery apparatus and systems that are suitable for use with flow-through print heads.
  • Printing systems having various forms of ink delivery systems are found in the art.
  • a number of conventional systems that supply larger quantities of ink - for example to printers - are most commonly passive - i.e., employing gravity feed, capillary feed siphons, and the like.
  • Many such systems are constrained by the effects of gravity and/or require the maintenance of specific constant heights between components of the system.
  • many conventional ink delivery systems either cannot deliver ink to print sideways (or directions significantly from vertical), or they cannot do so well.
  • the US 7,210,771 B2 discloses an ink delivery system in an inkjet printer, comprising among other things a print cartridge mounted on a carriage, the print cartridge having a print head including a plurality of nozzles to eject ink droplets for image printing, an ink container and an ink reservoir for receiving ink therein from the ink container and a flexible plastic tubing connected to an ink exit opening in the ink reservoir at one end and connected to the print cartridge at the other end.
  • the US 2008/136860 A1 discloses a liquid droplet ejection mechanism comprising a first ink tank and a second ink tank which store ink; a plurality of ink chamber units which are capable of ejecting the ink; a first common flow channel which connects the first ink tank with the plurality of ink chamber units; and a second common flow channel which connects the second ink tank with the plurality of ink chamber units; wherein each of the plurality of ink chamber units includes a pressure chamber which supplies the ink to a nozzle capable of ejecting ink.
  • the US 2008/158320 A1 discloses an ink jet recording apparatus comprising: an ink jet head having a pressure chamber opposed to a nozzle, an upstream port that communicates with the pressure chamber , and a downstream port; a first tank that communicates with the ink jet head via the downstream port and is capable of storing an ink; a second tank that communicated with the first tank and is capable of storing the ink; a third tank that communicates with the ink jet head via the upstream port and communicates with the second tank and is capable of storing the ink; an opening and closing mechanism that is capable of opening and closing a circulation path that connects the ink jet head, the first tank, the second tank, and the third tank; and air pressure adjusting mechanism.
  • the US 2008/079759 A1 discloses an inkjet recording apparatus, comprising: pressure chambers connected via nozzle flow channels to nozzles which eject ink; ink supply ports via which the ink is supplied to the pressure chambers; a circulation flow channel; and actuators which changes pressure in the pressure chamber to eject the ink from the nozzles.
  • a method for printing comprises an ink delivery system which includes a plurality of flow-through print heads in direct fluid communication by conduit or passageway between two tanks.
  • the method provides a pressure differential across the print heads to cause ink to flow through the print heads and into one of the tanks, such that ink can be controllably dispensed from the print heads irrespective of the orientation of the print heads with respect to the direction of the force of gravity controlling or adjusting the pressure differential to maintain a substantially constant meniscus pressure at the plurality of print heads including changing the position or orientation of one or more of the plurality of print heads.
  • the print head may be provided to control pressure differentials and print heads may print at one or more angles.
  • FIG. 1 generally illustrates an ink delivery system 10 in accordance with an embodiment of the invention.
  • Ink can be supplied to the system 10 from a source, e.g., bulk ink tank TBI, which may include a level sensor LS-TBI.
  • the bulk ink tank TBI may be open to atmospheric pressure, and the bulk ink tank TBI is in fluid communication with a first tank T1, which may also include a level sensor LS-T1.
  • the bulk ink tank TBI and the first tank T1 may be connected by a conduit or passageway 20, and the conduit or passageway 20 may include a make-up fill valve V1 and a flow restrictor FR-7 for controlling flow between the bulk ink tank TBI and the first tank T1.
  • the term "conduit” or “passageway” may comprise various forms of rigid or flexible paths, and may comprise, for example and without limitation, a hose, tube, supply line, or other conventional means for supplying ink from one component of the system to another.
  • Pressure in first tank T1 may be regulated by a regulator VR-1, which may include a valve and can control or regulate the pressure in first tank T1 to provide a vacuum.
  • regulator VR-1 may regulate the pressure in first tank T1 to approximately -350 mbar.
  • Make-up fill valve V1 may open to permit the vacuum associated with first tank T1 to draw ink from the bulk ink tank TBI. Ink can be permitted to flow from the bulk ink tank TBI into the first tank T1 until a specified fill level is reached - which may be signaled, for example, by a level sensor LS-T1. Once a specified or desired fill level is sensed or otherwise detected, make-up fill valve V1 can be closed.
  • Make-up fill valve V1 can again be opened as need so that the fill level of first tank T1 can be maintained continuously. It is noted that several sensor-and-valve feedback control loops are envisioned in connection with the system and the implementation of such controls will be readily understood by those of skill in the art.
  • system 10 is further shown to include a second tank T2 and a third tank T3.
  • tank as used herein, is intended to be construed broadly to include various types of ink-retaining tanks and/or various forms of fluid chambers.
  • each tank T2, T3 may additionally include reservoirs that are in communication with each other and are separated, at least in part, by a weir or overflow control barrier (hereinafter referred to as a "weir").
  • weirs can be configured to serve, at least in part, as a means to provide a hydraulic dampening effect to the system.
  • second tank T2 may include a first reservoir RES.
  • third tank T3 may include a third reservoir RES.3 and a fourth (secondary) reservoir RES.4, the third and fourth reservoirs being separated by a weir W-2.
  • each of the aforementioned reservoirs, RES.1, RES.2, RES.3, and RES.4, may include a corresponding level sensor - generally illustrated in FIG. 1 as LS-3, LS-2, LS-5, and LS-4, respectively.
  • FIG. 1A generally illustrates an embodiment of a system similar to that shown in FIG. 1 . However, the tanks included in system 10A in FIG.
  • system 10A may be modified such that only one fill measurement is detected in connection with of tanks T2 and T3. This can be accomplished, for example and without limitation, by including a single sensor in connection with each tank - i.e., sensor LS-2 (tank T2) and sensor LS-4 (tank T3).
  • first tank T1 and second tank T2 may be in fluid communication - for example via a conduit or passageway 30.
  • ink may be pumped from first tank T1 to T2 (or to first reservoir RES.1 of second tank T2) via a pump P, such as a fill pump.
  • the ink may additionally be pumped through or past a heater H, which can be activated to heat and/or maintain the ink at a desired or designated operating temperature prior to entering the second tank T2.
  • second tank T2 may be maintained at a positive pressure by a regulator VR-2.
  • second tank T2 may be maintained at a pressure of approximately +30 mbar.
  • Ink provided to the second tank T2 may flow into and fill first reservoir RES.1. Once first reservoir RES.1 is filled to a certain level, ink will flow over weir W-1 into second reservoir RES.2. In an embodiment, the flow of ink into second tank T2 may be maintained at a sufficient volume so that first reservoir RES.1 is consistently full (e.g., to the top of the weir) and ink may be overflowing into the second reservoir RES.2.
  • a valve V2 may be opened to permit ink to flow (e.g., via conduit or passageway 32) from second tank T2 into third tank T3 (i.e., into third reservoir RES.3 of the third tank T3).
  • the third tank T3 may be maintained at a vacuum by a regulator VR-3 to facilitate the described ink flow (i.e., from T2 to T3).
  • third tank T3 may operate in a similar manner as previously discussed in connection with ink flow into second tank T2. That is, third tank T3 may be configured so that by having a sufficient volume flow of ink to maintain the third reservoir RES.3 in a filled and/or overflowing into fourth reservoir RES.4. As the fill level of ink in the third reservoir RES.3 rises, and level sensor LS-4 detects a full or designated fill level, a valve V3 may be opened to permit ink to flow from the third tank T3 back to the first tank T1.
  • system 10 can be configured to provide a continuous flow loop in which ink is supplied from first tank T1 and the portion that is not printed along the route of the system is returned to first tank T1.
  • the system 10 may additionally include drain valves V4 and V5 that are in fluid communication between first reservoir RES.1 and the first tank T1, and between the third reservoir RES.3 and the first tank T1, respectively.
  • the system 10 may include one or more print heads - e.g., PH1, PH2, and PH3 - in fluid communication with the first reservoir RES. 1 of second tank T2 and the third reservoir RES.3 of tank T3.
  • the print head or heads used in connection with the system can comprise various types of flow-through print heads.
  • the print head/system may comprise a digital drop-on-demand ink jet or ink jet system.
  • the invention is not limited to a specific type of print head, and various other types and forms of print heads may be used.
  • conduits or passageways 40, 60, and 80 flow from the first reservoir RES.1 into print heads PH1, PH2, and PH3, respectively.
  • conduits or passageways 50, 70, 90 flow from print heads PH1, PH2, and PH3 to the third reservoir RES.3.
  • one or more of the conduits or passageways associated with the one or more print heads may include a flow restrictor.
  • flow restrictors may comprise various forms of restriction devices or apparatus used to provide fluid restrictions for tubes or passageways.
  • each of the conduits or passageways leading into the print heads (e.g., 40, 60, 80) and each of the conduits or passageways leaving the print heads (e.g., 50, 70, 90) may include a flow restrictor - see, e.g., flow restrictors designated FR-2 and FR-1 (PH1), FR-4 and FR-3 (PH2), and FR-5 and FR-4 (PH3).
  • a flow restrictor - see, e.g., flow restrictors designated FR-2 and FR-1 (PH1), FR-4 and FR-3 (PH2), and FR-5 and FR-4 (PH3).
  • a flow restrictor FR-8 may be included and used to balance/control flow between the second tank T2 and the third tank T3, and a flow restrictor FR-9 may be included and used to balance/control flow between the third tank T3 and the first tank T1 (e.g., example along illustrated conduit or passageway 100).
  • the conduits or passageways themselves may be, i.e., serve or function, as the flow restrictor.
  • one or more of the conduits or passageways may be configured (e.g., may have a given internal diameter) so that, in the context of the system and the associated fill/pressure regulation, the conduit or passageway itself is, or serves, as a flow restrictor.
  • the configuration of the conduit or passageway itself e.g., 32
  • regulators VR-3 and VR-2 which may be vacuum regulators associated with the second and third tanks T2, T3, respectively, can be maintained at specific or controlled values to cause or impart a pressure differential across the print heads.
  • the pressure differential can be used to control the flow of ink through the respective print heads.
  • the flow rate of ink through an individual print head can be, at least in part, controlled by the associated flow restrictors.
  • the flow restrictors along with the pressure differential set/control the flow volume of ink as well as the required meniscus pressures associated with the print head-and-ink combination.
  • a system 10 can be configured to permit the print heads to be at any orientation relative to gravity. That is, given the flow provisions associated with the system 10, which are not dependent upon gravity feed and height differentials between tanks and print heads, the system 10 can provide one or more print heads that are configured to print at various (non-vertical/downward) angles with respect to an intended target object.
  • flow provisions associated with the system and the print heads can include, for example, pressure/vacuum regulating devices, engineered flow restrictions, and the provision of a closed loop in system that is not open to atmosphere while in operation.
  • systems that are configured in accordance with the teachings of the present invention can, as the print heads are oriented, regulate and control associated pressure to maintain a constant meniscus pressure at the print heads.
  • FIG. 2 generally illustrates an ink delivery system 10' in accordance with another embodiment of the invention.
  • the system 10' illustrated in FIG. 2 is similar to that shown in FIG. 1 ; however, certain valves have been replaced by pumps.
  • valves V1, V2, and V3 illustrated in FIG. 1
  • pumps P 4 , P 2 , and P 3 respectively.
  • the flow restrictors maintain various pressure within the tanks and the plurality of pumps serve, at least in part, to maintain level control.
  • pump P 1 - which supplies ink from tank T1 - may be run at a substantially constant rate. The rate may be faster than the rate that the associated print heads draw ink.
  • Pump P 2 - which supplies ink from tank T2 (RES.2) to tank T3 (RES.3) - may be run at a lower pump speed/flow than pump P 1 . Ink then may be drawn from T2 at a slower rate than ink is delivered to T1. Consequently, the level in tank T2 rises. If pump P 2 is run at a speed/flow that is faster than pump P 1 , then the level of ink within tank T2 will decrease. When pump P 2 is again slowed down, ink will again fill tank T2.
  • the ink levels associated with tank T2 may be controlled by changing the rate/flow associated with the running of pump P 2 .
  • the level associated with Tank T3 may be controlled, at least in part, by controlling the running of pump P 3 .
  • the various pumps may be run to maintain desired ink levels in the associated tanks.
  • the use of pumps can provide smooth rate/flow transitions, as the pumps may be constantly moving and their relative rates/flows may be controlled to provide desire fill levels fairly dynamically. As such the system may be controlled by speed/flow changes associated with the pumps rather than requiring the opening/closing of components in the flow path.
  • FIG. 3 generally illustrates an ink delivery system 10" in accordance with another embodiment of the invention.
  • System 10" illustrated in FIG. 3 is a "closed" system but includes certain similarities to the system 10' shown in FIG. 2 , and also does not require the inclusion of valves, such as valves V1, V2, and V3, or even tanks with reservoirs, as generally shown in FIG. 1 .
  • the embodiment of system 10" shown in FIG. 3 includes a plurality of pumps e.g., pumps P 1 , P 2 , P 3 , and P 4 .
  • pump controller PC is provided between tanks T2 and T3. Pump controller PC may also be in operative connection with one or more pressure transducers (e.g., PT-1 and PT-2), as generally illustrated.
  • vacuum regulators are not required. That is, the printing associated with the embodiment of the system may be controlled based on flow control rather than tank fill level control.
  • pump P 4 is not associated with a "pulled vacuum.” Rather, when a need for ink in Tank T1 is determined or sensed, pump P 4 can be configured to provide a supply of ink.
  • a pump P 2 may also be provided between tank T2 and tank T3, and pump P 3 may be provided between tank T3 and tank T1.
  • a pump controller PC may be provided between tanks T2 and T3. With system 10" pressure sensors associated with tanks T2 and T3 provide feedback to pump controller PC - which, in turn, may be used to provide control instructions (e.g., pump speed control) to pumps P 1 , P 2 , and/or P 3 .
  • Coordinated operation of the pumps can provide system 10" with desired pressures and ink delivery for printing.
  • a tank e.g., tank T2
  • the pressure in the tank will increase.
  • a subsequent pump in the system e.g., P 2
  • the speed/flow associated with an associated pumps e.g., P 2 and P 1
  • pump P 3 may, for example, be run faster to maintain a negative pressure with respect to tank T3 (and provide for continued flow of ink from tank T2 to tank T3 through the print heads (e.g., PH1, PH2, and PH3).
  • the associated print heads can be oriented in any way with respect to gravity and still deliver a desired amount of ink through the print heads. Consequently, the present invention permits, among other things, the print heads to be able to print in any given direction (including those opposing gravity) to print in any given orientation without modifying the associated ink delivery system. Moreover, such changes in print head orientations can be handled dynamically, i.e., without requiring the stationary periods between printing.
  • embodiments of the invention may be very useful in connection with printing, e.g., digitally printing, on the surfaces of various articles, such as printing labels and/or other matter on various forms of plastic containers.
