    A fluid (liquid or water) cleaning device 46 is used to clean the front surface of the inkjet printer cartridge 17. In addition, the nozzle plate 24 blocks the ink 32 from splashing on the nozzle array 23. In an inkjet printer, ink droplets are ejected from an array of holes in the nozzle plate in the print head. While the ink droplets are ejected, the ink is sprayed and deposited around the holes. Ink droplets are attached to the paper web 14 adjacent to the nozzles, and portions of the droplets fly behind the coating surface of the nozzle plate. Some ink leaks onto the array of nozzle holes 23. Ink coatings tend to stick particles and clog pores. The ink coating cleans the nozzle surface with fluid flow and in some embodiments flows over the nozzle hole itself. Fluid 46 is water, ink or other liquid and is channeled across the nozzle surface, and the fluid is air flow and flows across the nozzle surface.

    Apparatus and method for cleaning continuous ink jet nozzles
    Instant inkjet and bubblejet printers (collectively referred to as inkjet printers) eject very small droplets of ink from the nozzle towards the paper adjacent to the nozzle. An example of these types of printers is Canon's nozzles known as BC01 and BC02. By precisely controlling the ejection time and trajectory of the ink droplets, the inkjet nozzles print clean dots on the paper. In order to achieve precise positioning of the ink droplets, the inkjet nozzles must be provided with clean and clear holes for ink droplets to pass through the nozzles as the ink droplets fly from the nozzles to the surface of the paper. In a typical instant inkjet nozzle, there was an array of several holes on the surface of the nozzle that ejected the ink droplets. During printing, ink is ejected through selected holes in the array to draw the desired image on the paper. The ejection of ink droplets impinging on the surface of the paper produces a spray of inks covering the surface of the nozzle. In addition, during ejection into ink droplets, unnecessary ink is sprayed and accumulated on the nozzle face adjacent to the hole. This dry ink coating prevents paper fibers, dust, tees and other types of particles from clogging the nozzle holes and blocking ink sprayed from the nozzles. In addition, unnecessary ink is accumulated to block the holes. Therefore, the hole array needs to be kept clean so that ink does not accumulate, and it is necessary to periodically clean the nozzle plate of the inkjet printer so as not to disturb the printing of the ink on the paper.
    Conventionally, inkjet printers have been cleaned with a wiper mechanism for wiping nozzle plates and holes. During the printing operation the print head moves from the paper web to the cleaning station where it slides against the cleaning wiper. These wipers are pressed across the face of the hole and nozzle plate to remove particles that are blocking the ink in the nozzle. Since the wiper itself temporarily blocks the nozzles, the wipers are only used when the inkjet printer is not printing. For example, the wiper may be located at the far end of the path of the carriage away from the edge of the paper supported in contact with the carriage path. An example of a wiping system is disclosed in US Pat. No. 5,126,765 in which the name of the invention has cleaning means for cleaning the recording head.
    It has been found that wiper devices are acceptable for tabletop printing applications where each individual print job is relatively short and relatively simple when cleaning the printer nozzles. In a typical tabletop inkjet printer, a carriage with an inkjet print head can be converted to a cleaning station after each print job. Therefore, in conventional tabletop applications, the printing nozzles need to be cleaned frequently with conventional wiper rolls and do not tend to clog particles.
    In a continuous web feed printing apparatus, the printer nozzle is required to continue printing for several hours. This is undesirable for typical tabletop printing applications where each print job is relatively short. Switching the print head to a wash station remote from the paper to be printed needs to interrupt the print job of the continuous printer. Although this interruption does not practically disrupt typical desk printing operations, this hinders commercial printing of continuous webs. In this regard, it has been found that conventional inkjet printer heads need to be cleaned after every 30 to 60 hours of continuous printing. Remote cleaning stations for inkjet printers are not desirable for commercial continuous printers because the print job must be interrupted every half to one hour to clean the nozzles. Thus, there has long been a need for a method and apparatus for cleaning inkjet nozzles without interrupting printing.
    Other conventional techniques for cleaning the nozzle face of an ink jet printer have been to blow particles at or around the ink nozzle to blow particles off the nozzle face or to prevent particles from sticking to the nozzle. Some of these techniques involve the use of ionized air to neutralize the electrostatic charge of dust particles that are attracted to the nozzles. These techniques have only been partially successful, as the name of the invention is disclosed in US Pat. No. 4,411,706, which is a method and apparatus for removing dust from an inkjet printer. Blowing air into the nozzle is achieved when the nozzle sprays ink, while turbulent flow of air in the prior art hinders the trajectory of the ink droplets on the paper. Since conventional systems for cleaning inkjet nozzles are not satisfactory, techniques for effectively cleaning nozzles have long been required. Such a request was not entirely satisfactory until the present invention.
    The present invention relates to printer nozzles, and more particularly to instant printer nozzles, such as inkjet and bubblejet printer nozzles.
    The invention will be described in detail with reference to the accompanying drawings as follows.
    1 is a cross-sectional view of an inkjet printer with an associated fluid cleaning mechanism forming a first embodiment of the present invention.
    FIG. 2 is a front view illustrating the inkjet printer surface shown in FIG. 2.
    3 and 4 are cross-sectional and front views respectively showing another embodiment of the present invention.
    5 is a front view showing another embodiment of the present invention.
    6 and 7 are front views showing another embodiment of the present invention.
    The present invention relates to a method and apparatus for cleaning an inkjet nozzle with a fluid, such as water or air, flowing across the printing nozzle surface to entrain dust and paper particles sticking to the nozzle surface. Once particles are entrained in the fluid, they are removed from the nozzle by the flow of the fluid.
    In one embodiment of the present invention, the fluid flow flows across the nozzle face of the inkjet printer to clean the printer. This flow is located adjacent to the nozzle array from which the ink droplets eject. Dust and paper particles that may clog the nozzle array are entrained into the fluid flow prior to clogging the nozzles. The network of fluid sources, drainage feed fluids, and fluid channels in the nozzle creates a fluid flow path that is employed to remove particles and dust near the nozzle array. Continuously flowing fluid across the nozzle face continuously collects ink, debris and paper particles and removes them from the nozzle array. In some embodiments, the fluid flow does not interfere with the ejection of ink droplets from the nozzle array and thereby does not interfere with printing.
    In a first embodiment of the invention, the cleaning fluid is contained in a channel adjacent to the nozzle hole. The hole does not pass through the fluid. Thus, the inkjet nozzles can print while the cleaning fluid flows because the fluid flow does not prevent or hinder ink droplets ejected from the nozzle onto the paper. Accordingly, the first embodiment of the present invention provides an apparatus and method for continuously removing particles from an inkjet printer side while printing.
    In a second embodiment of the invention, the cleaning fluid generally flows directly into the printing nozzle aperture to clean the aperture and nozzle. Printing is stopped and the holes are cleaned using the second embodiment. The hole cleaning embodiment of the present invention wipes off ink residues, dust or paper fibers blocking the holes. Therefore, the second embodiment cleans the print nozzle more thoroughly than that of the first embodiment. The second embodiment of the present invention may be used together with the first embodiment.
    In the third embodiment of the present invention, the array of nozzle holes is blocked from ink spraying and scattering by the nozzle plate. The nozzle plate includes a narrow slit located in front of the hole and through which ink droplets can scatter. The nozzle plate is separated by a small gap from the array of nozzle holes and excess ink is discharged away from the nozzle hole through the gap. The third embodiment can be used with the first and second embodiments of the present invention.
    It is an object of the present invention to clean a nozzle array of an inkjet printer and to prevent the holes in the nozzle array from being blocked by ink, dust and paper particles. Another object of the present invention is to continuously grasp the ink and paper particles of the nozzle array and to thoroughly clean the nozzles while the nozzles are printing. It is another object of the present invention to extend the period for maintenance-free printing of inkjet printers and to reduce frequent stops for the cleaning required in inkjet printers. It is also an object of the present invention to overcome many of the problems caused by dust, debris and paper particles that have clogged the prior art inkjet printers, thereby improving printing improvements of the inkjet printers. These and other objects are achieved by the present invention shown and described below.
    1 shows an inkjet printer head 10 mounted as a carriage on an axis 12 in a printing mechanism. In particular, the printing apparatus may be a conventional continuous web feed printer for high volume computer printing. In these printers the speed of the web is typically 300 feet per minute and the working speeds in the range of 200 to 500 web feet per minute are normal. In addition, these printers operate continuously and print for as long as 12 hours without interruption, and the inkjet printer is not interrupted during this period.
    The paper or other web is moved as web 14 in the direction of arrow 15. The web is moved across the surface of the platen 16 adjacent the printer head. The platen is generally parallel to the inkjet printer and positioned to print directly to the front of the printer. The printing mechanism includes a conventional web handling device (not shown), ie a tractor feeder, to move the web at a predetermined speed in a precisely controlled manner along a predetermined course. The inkjet printer head is attached to the shaft by a bracket 17 such that the printer head is fixed in position on the shaft and arranged in an array with other printer heads evenly spaced across the width of the web. The print head may also be moved back and forth across the axis and slidably mounted thereon in a controlled manner during printing to position the print head relative to the moving web. The bracket may also include pins 18 for dissipating heat away from the inkjet printer head. The thermocouple may be attached to the base of the heating pin for sensing the temperature of the print head. The bracket is formed of a suitable aluminum or other material to firmly support the inkjet nozzle assembly.
    The inkjet nozzle assembly includes a mounting plate 19 on the front side of the print head bracket 17. The mounting plate supports the print head in the grooves 20 of the bracket. The plate covers the bracket groove and is removably attached to the bracket by screws or other fastening devices. The mounting plate includes a rectangular hole 21 and thereby includes a front nose 22 of the print head. The array of nozzle holes 23 is located on the front surface of the nose of the print head. The mounting plate is formed of machined copper and coated with a hydrophilic coating, ie Teflon, near the area of the aperture 22 to reduce the tendency for excess ink to clog the aperture.
    The nozzle plate 24 covers the mounting plate and the nose of the print head. The nozzle plate is attached to the mounting plate or bracket by screws or other fastening device. The seal 25 may be located between the nozzle plate and the mounting plate to prevent the cleaning liquid from leaking out of the gap between the two plates. The nozzle plate also includes a narrow slit 26 aligned with the array of nozzle holes in the print head to allow ink droplets to flow from the hole through the slit 26 toward the paper web 14. The slits are aligned with the array of nozzle holes. In addition, the slits have holes with an area only slightly larger than the area of the nozzle array. The nozzle plate may be formed of a porous material so that ink dispersed in the nozzle plate can be discharged through the plate into the gap between the rear portion of the nozzle plate and the mounting plate.
    The nozzle plate prevents ink droplets from striking the print head when ink droplets impinge the paper web. The ink spray collects on the outer surface of the nozzle plate instead of being bounced back into the nozzle array. In addition, the ink that bleeds into the gap 40 between the mounting plate and the nozzle plate is blocked from paper and web fibers and other particles that tend to wet the surface with ink. Ink that collects on the nozzle surface 48 of the print head is not collected by web fibers and other particles because of the nozzle plate. Because of the existence of a unique nozzle plate, it is believed that printing can be extended for several hours (relative to half to one hour) and the print head nozzle can be continuously printed between washings.
    Ink droplets 27 are ejected from the nozzle holes 23 in the direction of the paper web 14 for printing. When ink droplets impinge on the web, most of the ink remains on the web as a point 30 or other mark. Some ink splashes and strikes the paper and forms a spray of ink particles 32. In addition, ink droplets are ejected from the nozzle holes to produce ink spray residues. This ink spray rises near the nozzle plate, the print head nose 22 and the paper web, and tends to form on these surfaces as the ink coating 34 that occurs as ink printing continues. Since the paper web is moved, it is not stacked to be noticeable on any part of the web. The print head does not move. Therefore, the ink accumulated on the print head surface has various problems, but is solved by the present invention.
    The impact of ink droplets, the movement of the paper web and other factors caused by the paper fibers and other fine particles 36 deviate from the web and other surfaces and float in the ink spray. In addition to the build up of ink around the nozzles caused by ink spraying, some of these particles contribute to the deposition of ink and particles 34 in the vicinity of the inkjet nozzles. If such deposition continues without being removed by washing, the deposition causes the nozzle holes 23 to be clogged and the ink printing to stop. The need for the nozzle plate to wipe off large amounts of ink spray and discrete particles is entirely avoided. The present invention also includes a technique for removing particles and preventing printing from depositing around the nozzle hole while continuing printing.
    It has been found that the coating of the nozzle array can be cleaned by washing across the face of the nose 22 of the print head, its ink and particles with a fluid such as water or air. In one embodiment, the water is supplied from the water source to the gap 40 between the mounting plate 19 and the nozzle plate 24 via a conduit passing through the bracket 17 and the mounting plate and at the front of the mounting plate. Eject from relatively wide hole (s) on the surface. The fluid discharged into these holes enters the gap 40 between the mounting plates and the nozzle plates, and flows downwardly between these plates, shown by arrows 46, toward the print head. When the fluid reaches the print head nose 22, it flows over and wets the front surface 48 of the nose. In this way, the ink, web fibers and particles coated on the front surface of the nose are washed by the fluid.
    The fluid, along with the ink, fibers and other particles, flows downward through the gap between the mounting plate and the nozzle plate until it reaches the suction hole 50 in the mounting plate. Since a slight suction force is applied to the hole, the fluid is discharged into the hole and through the conduit 52 to the outlet (not shown). Fluid, which may be water or other liquid, may be discharged or filtered through the printer and may be recycled. Alternatively, the fluid discharged by suction into the suction hole 50 may be surplus ink in the gap 40 between the mounting plate and the nozzle plate. The suction force of the fluid produces a capillary force in the gap through which the ink is discharged downward from the nozzle array into the suction hole. In this alternative embodiment, the separate fluid source, supply conduit 42 and fluid discharge hole 44 on the printer head are unnecessary because excess ink itself is used as the cleaning fluid.
    If a cleaning fluid such as distilled water is supplied, printing may be interrupted or continued during the fluid cleaning of the front surface of the nozzle along the flow path of the fluid across the face of the nozzle array. If the flow of fluid is strong across the entire nozzle array, the fluid will clean the holes 23. While this powerful flow is particularly effective at cleaning clogged printing holes, the fluid will interfere with the ejection of ink droplets, whereby printing may be stopped or stopped for a powerful flow of cleaning fluid. Alternatively, a weak flow of fluid to the front surface 48 of the nozzle and / or the channel on the mounting plate may be used while continuing printing since the channel does not cut across the printing hole and thereby does not interfere with the ink flow. Surplus ink, fibers, and other particles can be included in these channels by coating the channel and the surface adjacent to the channels with a hydrophilic coating. Fluid in the channels carries ink, fibers, and other particles from the front surface of the nozzle array to suction holes 50.
    In another embodiment, the single fluid of the first embodiment, as shown in FIGS. 3 and 4 (where the reference numerals used in FIGS. 1 and 2 are used for the parts common to all the figures). The course was changed to a dual path system of fluid for cleaning excess ink, paper fibers and other particles. This fluid reverse cleaning may cause the print head not to print while the cleaning may interfere with the print job. The pair of fluid conduits 60, 62 extend from the pair of outlets 64 to a fluid source (not shown) and to the first and second fluid outlet ports 66, 68, respectively. In this embodiment, the nozzle plate is attached directly to the mounting plate by screws 74 or other attachment means.
    The first discharge port 66 is opened from the bracket 17 into the gap 70 between the print head and the front surface portion 72 of the bracket and the nozzle plate, the surface portion comprising the front surface of the nozzle 48. do. The fluid flows downwardly through the gap until it passes through the holes 23 of the nozzle array. Under the nozzle array, the front surface of the print head descends along the inclined portion until it meets the other vertical portion 76 where the suction hole 50 for the bracket terminates. The inclined surface widens the gap 70 into a relatively large reservoir 78 where fluid, excess ink, web fibers and other stacked particles gather. The fluid flows downward into the reservoir and is discharged by capillary force into the suction hole 50 of the bracket.
    Similarly, the second fluid conduit 68 carries the fluid to the second outlet port 68, which constitutes a row of holes as shown in FIG. 4, through which fluid is directed to the surface of the nozzle plate 19. Discharged. The fluid cleans the front surface of the nozzle plate as the fluid flows down across the surface of the plate. In the slits 26 in the nozzle plate 24, fluid portions may flow around, in whole, and inwards. Fluid flows around and throughout the slit to wash the ink and particles collected in the plate. This outer path fluid, ink and particle mixture flows downward over the nozzle plate (surface tension that maintains the flow on the plate surface) until the fluid exits the hole in the nozzle plate in communication with the suction hole 50 of the bracket. To form. Fluid is discharged into the slit to clean the slit and into the cavity 78 between the nozzle plate and the printer head, from which the fluid, ink and particle mixture is discharged into the suction hole 50 of the bracket.
    Figure 5 illustrates another embodiment of the present invention, wherein a pair of fluid flows is directed to the front surface 48 of the nozzle on one side of the nozzle array 23 for cleaning ink from the surface 48 while printing. Flows across. The embodiment can be practiced with or without a nozzle plate (as shown). A pair of horizontal fluid conduits 90, 92 mounted on or within the mounting plate 19 is connected to a fluid source (indicated by arrow 94) and exits from a hole adjacent the front surface 48 of the print head nozzle. . The fluid from the discharge holes enters a pair of channels 98, 100 opposite and parallel to the sides of the nozzle array 23. Channels and surfaces adjacent the channels and nozzle holes do not allow ink to collect in these areas and may be coated with a hydrophilic material to be discharged into the channels and cleaned by channel flow. When the fluid in the channel reaches the opposite end of the channel, the fluid is discharged into the holes 102 and 104 on the mounting plate by suction. These orifices are connected to conduits 106 and 108 connected to outlet 110 to draw suction into conduits and orifices 102 and 104 such that fluid is discharged through the channels.
    6 and 7 illustrate another embodiment of the present invention, which is employed to use air (or other gas) as the cleaning fluid. Air bellows manifold 112, such as an ellipse funnel, provides a low pressure air flow horizontally (FIG. 6) or vertically (FIG. 7) across the front surface 48 of the nozzle array 23. The bellows pipe is connected to a compressed air source (not shown). Air flow pressure flows into the wet ink on the front surface of the nozzle array and causes the ink (including the fibers and particles included) to flow from the bellows 112 toward the vacuum manifold 114, which may have a bellows-like shape. The vacuum manifold collects the ink flow and directs it toward a drain (not shown) (see arrow 116). The vacuum manifold may also be connected to a vacuum pump to exhaust air across the nozzle array and into the manifold. The trajectory of the inkjet nozzle varies depending on the pressure of the air flow across the nozzle array, and the manifold and vacuum manifold may or may not be operated while printing is in progress.
    The present invention has been described in terms of the most practical and preferred embodiments. The invention is not limited to the described embodiments and includes various modifications and equivalents without departing from the spirit and scope of the appended claims.
