Definitions

  • the present invention relates to a method and apparatus for replenishing an ink-jet print head with ink and more particularly to a device for use with ink-jet print heads incorporating an ink reservoir confining a porous body soaked with ink.
  • the connecting tube Since the head is mounted on a carriage movable along a line of print, the connecting tube must have a considerable length in order to cover the maximum distance of the head from the main reservoir. Moreover, during the to-and-fro movement of the carriage, the tube is repeatedly bent, with the risk of the tube itself being damaged.
  • a further drawback which restricts, over time, the use of such a device is in the fact that repeated insertion and withdrawal of the needle into/from the sponge causes the walls to be perforated with a large number of pores resulting in a reduction in the capillary action in the part of the sponge adjacent to the needle. This drastically reduces the sponge's capacity to be charged with a fresh supply of ink.
  • Preferred embodiments of the present invention provide a device for continually replenishing a print head designed to be repeatedly supplied with ink any number of times, without damage to the sponge contained in the head reservoir.
  • the replenishing device consists of a connecting element made of porous material and having one end immersed in a main ink reservoir. ,The other end can make contact with the spongy body in the print head ink reservoir via a hole in the wall of the head's reservoir. When the spongy body is partially empty of ink the porous connecting element supplies further ink thereto by capillary action.
  • the spongy body of a print head is replenished each time the head stops in a parked position, for example during replacement of a sheet of paper.
  • Figs. 1-4 illustrate the physical principle on which the ink replenishing device according to the invention is based.
  • the greater negative pressure existing in the spongy body which is less soaked with ink causes ink to be drawn from the other, more soaked body 2 until an equilibrium is established between the negative pressures in the two bodies 1 and 2. Therefore, since the body 2 is completely soaked with ink, being immersed in a main reservoir 4 full of ink 5 with a free surface making contact with the atmosphere via a hole 6, the body 1, when it is partially empty of ink, sucks ink from the reservoir 4 until it is almost entirely impregnated.
  • Figures 2-4 illustrate a few useful measures for ensuring initiation of the ink suction process by the spongy body 1.
  • a spongy body 1 is contained in a reservoir 10 having a hole 12 formed in a wall 11 for accommodating the body 2.
  • a sleeve 14 is inserted into the hole 12, said sleeve projecting inside the reservoir 10 so as to create in the spongy body 1 a zone 15 which is more compressed and therefore has a greater capillarity than the part of the sleeve 14 which is further away.
  • the zone 15 will be the last zone to be emptied. Therefore, by arranging end-of-ink sensors (not shown in the drawings) in the vicinity of the zone 15 it is possible to know when this zone starts to become empty. By bringing at this point the free end 2′ of the body 2 up to the body 1 through the sleeve 14, hydraulic continuity is established in a reliable manner between the two bodies 1 and 2.
  • Fig. 3 shows the use of a spongy body 2 which is per se more rigid than the spongy body 1, or has been rigidified by a tubular support 16.
  • the body 2 is pressed through the hole 12 against the spongy body 1 so as to compress it locally inside the contact surface 3.
  • the latter is packed inside the reservoir 10 so as to form a zone 18 which is more compressed in the vicinity of the bottom 11 and the hole 12.
  • Fig. 4 shows the use of a thin layer 20 of a rigid porous material, for example porous ceramic or Porex (registered trademark), i.e. a sufficiently rigid thin sheet which is obtained using sintered nylon microscopic balls.
  • the porous layer 20 advantageously replaces the measures illustrated in Figs. 2 and 3.
  • Fig. 5 illustrates use of the principle of replenishment of the reservoir 10 with ink, in order to supply an ink-jet print head.
  • the reservoir 10 is filled with a spongy body 1, subsequently referred to simply as a sponge, packed on the bottom so as to form a more compressed zone 22 which is roughly delimited with respect to the upper part 25 by a broken line 24.
  • the side wall 28 has formed in it a hole 30 for accommodating a spongy or fibrous body 32, referred to below as a connecting element for the ink, of the type indicated by 2 in Figs. 1-4.
  • the element 32 consists of a porous or fibrous material having a plurality of capillary ducts arranged in a bundle each with a diameter varying between 50 and 500 ⁇ m.
  • the element 32 has an elongated cylindrical shape with a prismatic circular crows-section much larger than the cross-section of each capillary duct.
  • the transverse dimension or diameter of the element 32 may vary between 3 and 15 mm.
  • the hole 30 leaves exposed a part 34 of the surface of the sponge 1, up to which one end 36 of the element 32 is brought.
  • the element 32 may be made using one of the following materials:
  • the reservoir 10 carries an ink-jet print head 40 integrally fixed to its bottom part.
  • the head 40 may consist of a multi-layer plate 41 incorporating capillary cells each containing a resistance which can be actuated so as to expel drops of ink from corresponding nozzles 42 so as to print onto a horizontal sheet 43.
  • the reservoir 10 together with the head 40 are mounted on a structure 44 forming part of a movable carriage (not illustrated for the sake of clarity) of a printer.
  • the plate 41 may be, for example, of the type described in European Patent Application No. 401996 published on 12 December 1990, in the name of the present Applicant.
  • a main reservoir 48 filled with ink is arranged underneath the head 40 so that the level of the ink forms a pressure head H of about 1-3 cm with respect to the head 40.
  • the other end 32′ of the element 32 is immersed in the reservoir 48.
  • the hole 30 it is preferable for the hole 30 to be arranged so that it uncovers a zone of the sponge 1 where, owing to the compression exerted by the walls of the cartridge 10, there is a high degree of capillarity and hence the guarantee that this zone is emptied only just before all of the ink is used up.
  • the contact between the sponge and the element 32 should occur in a zone which is always soaked with liquid connected to the ink contained in a chamber 45 supplying the plate 41 so that the sucking action always occurs at the right time.
  • the chamber 45 is always kept full of ink so as to prevent the presence of air bubbles in it affecting proper operation of the head.
  • the zone 52 has been delimited by a (dotted) line 54 indicating a surface separating the part 52 with greater capillarity and the upper part 25 with reduced capillarity.
  • the measures illustrated in Figs. 2, 3 and 4 may be advantageously used to establish at the right time hydraulic continuity between the element 32 and the sponge 1.
  • the reservoir 10 may be replaced by a removable cartridge 55 (Fig. 6) inserted from above into the support 56 in turn mounted on the structure 44 of Fig. 5.
  • the cartridge 55 contains a sponge 1 soaked with ink.
  • the print head 40 is integral with the support 56 and is not replaced together with the cartridge 55.
  • the chamber 45 is delimited at the top by a sleeve 57 through which a porous or fibrous element 58 passes.
  • the element 58 is made using one of the materials listed above in connection with the element 32 of Fig. 5 and projects at the top by a distance so as to penetrate into a hole 59 of the cartridge 55 until it comes into contact with a free portion 60 of the sponge 1.
  • This system for achieving the hydraulic connection between the cartridge 55 and the chamber 45 supplying the plate 41 advantageously replaces other known and more complicated connecting systems which use, for example, a hollow needle associated with a filter for the ink.
  • the element 58 as a result of its own capillarity, establishes a hydraulic connection between the sponge 1 and the chamber 45, performing at the same time a rigorous filtering action as regards all the impurities which may be present in the ink. Furthermore, the element 58 prevents air from passing into the chamber 45 even when no cartridge 55 is present, thus ensuring that there are no air bubbles inside the chamber 45.
  • Fig. 7 illustrates an application, to an ink-jet printer, of the device for replenishing the reservoir of the print head with ink, in accordance with the invention.
  • a print head 61 of the same type as that shown in Fig. 5 is mounted on a carriage 62 movable along a guide 64.
  • the carriage is moved by a motor 65, via a cable 66, so as to print on a sheet 67 in both the directions indicated by the double arrow A.
  • the head 61 stops in a parked position R where an ink release element 70 comes into contact with the sponge 1 contained in the cartridge 10 of the head 61.
  • the release element 70 is entirely similar to that indicated by 32 in Fig. 5 and is formed using the materials listed above.
  • the bottom end 72 of the element 70 is immersed inside a main reservoir 74 fixed to the structure 63 of the printer.
  • the reservoir 74 contains 1 to 8 times as much ink as that contained in the cartridge 10 when the sponge 1 is completely soaked with ink.
  • the reservoir 74 is located lower down than the head 61 so that the pressure head H (Fig. 5) between the free surface of the ink inside the reservoir and the nozzles of the head 61 is between about 1 and 3 cm.
  • the element 70 releases to the sponge 1, as a result of the capillary action, a quantity of ink which substantially replaces that used during printing.
  • the dimensions of the reservoir 10 may be very small, for example so as to contain a minimum of 3 cc of ink, sufficient on average to print about 50 pages of standard A4 format.
  • Fig. 8 shows a printer using an ink-jet print head 75 (Fig. 9) for printing on a sheet 78 arranged vertically.
  • the head 75 is mounted on a carriage 77 and is integral with the reservoir 76.
  • a bottom wall 80 of the reservoir 76 has formed in it a hole 82 for exposing a portion 83 of the sponge 85 and for accommodating an ink release element 87 intended to replenish the sponge 85 with a fresh supply of ink.
  • the release element 87 is similar, as regards its shape and the material form which it is made, to the elements 32 of Fig. 5 and/or 2 of Figs. 1-4.
  • the element 87 is supported inside a sleeve 89 integral with a main ink container 90 mounted on the frame 93 of the printer and slidable vertically on guides 92.
  • the container 90 is situated underneath the reservoir 76 and in the region of a parked position R (Fig. 7) at one end of the travel of the carriage 77 where the print head 75 is kept immobile during a pause.
  • a lever 94 hinged at a point 95 of the frame 93 is rotated in a clockwise direction by the head 75 when it reaches the position R, so that an arm 94′ of the lever 94 raises the reservoir 90 so as to bring the element 87 into contact with the sponge 85.
  • the release element 87 consists of a material which is more rigid than the sponge 85. Therefore, the element 87 is pressed against the sponge 85 so as to create a limited compression zone 97, hence with a greater capillarity, so as to ensure the prompt and correct flow of ink between the reservoir 90 and the sponge 85.
  • a nozzle suction and protection device (not shown in the figures) is provided with an elastic cap surrounding the nozzles.
  • an elastic cap 98 is preferably applied to the support 89 in order to seal the opening 82 during parking of the head.
