Definitions

  • the invention relates to an arrangement for keeping the nozzles of an ink print head clean, in particular an ink print head with large numbers of nozzles, which is designed in a stacked construction from individual ink print modules.
  • Such ink printheads are intended for use in small, fast printers, which in turn are part of modern machines for franking mail or for printing addresses or for product labeling.
  • printing is carried out as a single print in one pass through the recording medium. Due to this much larger printing width - approximately one inch - the number of ink nozzles to be arranged one below the other is considerably larger than in the case of ink print heads for office printers.
  • EP-A-0 285 155 and EP-A-0 041 706 show an arrangement according to the preamble of claim 1.
  • the devices for carrying out these measures are either arranged outside the print area of the ink print head or are arranged on the print head in such a way that the distance from the recording medium is thereby determined.
  • a portable, movable ink printhead is required. This generally does not apply to franking machines, since here the mail is moved past the rigidly arranged ink print head.
  • the distance to the recording medium is increased so much that the print quality suffers as a result of the greater impact of misalignments, drop speed differences and the given recording medium speed.
  • a cover for the nozzles of a vacuum ink printhead which works with fast-drying inks is also known, compare EP 0 173 939 A1.
  • the cover is intended on the one hand to prevent the ink from drying out at the nozzle ends during the printing pauses, and on the other hand to ensure that the ink meniscus is neither touched nor pushed back.
  • the cover has a circumferential sealing element and a membrane, which form a pressure chamber when the cover is placed on the nozzle surface.
  • the inherent tension of the membrane is chosen to be smaller than the surface tension of the ink menisci. In this relatively small pressure chamber, the air quickly becomes saturated with moisture as a result of the ink solvents initially evaporating, so that drying of the nozzles is avoided over shorter printing pauses.
  • Another known device for cleaning the nozzle surface of an ink print head has a wiping element which is movably arranged in front of the nozzle surface and, in addition to the ink nozzles, a nozzle from which cleaning fluid is ejected against a deflector orifice and from it is redirected to the nozzle surface.
  • the wiping element consists of a belt which contains a plurality of cutouts lying next to one another in the belt direction and which is transported past the nozzle surface in one direction. Depending on the position of the belt, the nozzles are released - cutout - or covered.
  • the tape is designed as an endless tape and contained in a tape cassette with a drive.
  • the tape lies with one of its cutouts in front of the nozzle openings and releases them for ink ejection.
  • cleaning liquid is first discharged dropwise through the cleaning nozzle.
  • the belt is then moved so far in its transport direction that, instead of the cutout, the following belt section comes in front of the nozzle surface and covers it.
  • the edge of the cutout wipes over the nozzle surface and cleans it of any accumulated dirt.
  • the wiping element can be kept sufficiently thin so that the distance from the recording medium is sufficiently small. However, as is evident, this device is only used for rough cleaning of the nozzle surface. A smearing of the nozzle openings when the tape slides past is not excluded, nor is it possible for nozzles to dry out.
  • the purpose of the invention is to increase the reliability of ink print heads of the type described in the introduction with little effort.
  • the invention has for its object to find a solution with which all the nozzles of an ink print head can be quickly cleaned in the printing breaks and are protected against drying out.
  • cleaning should be possible when ink residues are deposited on the nozzle surface and the masses of the cleaning device to be moved should be small.
  • the cleaning device should have no influence on the distance between the ink print head and the recording medium and its transport speed.
  • the direct arrangement of a cleaning module on the ink print head which can consist of one or more ink printing modules, and the inclusion of the sealing cap in the cleaning process lead to a surprisingly small, compact arrangement with only small moving masses.
  • the ink print head is designed with angled nozzle rows, for example in the "non-interlaced design", the anyway free corner space can be used for the cleaning module.
  • the interruption of the printing operation for cleaning can be limited to the shortest possible time, since the sealing cap is freed of ink residues in the state pivoted away from the ink print head via the lateral suction channel, so that printing operation is possible here.
  • the design of the lever carrying the wiper lip with the two outer lugs ensures that the wiper lip always slides over the nozzle surface with the same placement force.
  • an ink print head 2 contains three ink print modules 21 and a cleaning module 22 which is lined up parallel to the ink print modules 21.
  • the front surface 201 of the inkjet print head 2 protrudes into a recess 10 in a guide plate 1.
  • the record carrier (not shown) or the mail item is guided past the guide plate 1 in the direction of the arrow.
  • the ink printing modules 21 and the cleaning module 22 are accommodated together in the housing 20 of the ink printing head 2.
  • a pin 2021 is formed on the top surface 202 of the housing 20.
  • a pin 2031 - not visible here - is formed on the bottom surface 203.
  • a gear 3 is rotatably fitted onto each pin 2021, 2031.
  • the gear wheel 3 has an outer ring gear 31 and within the latter a driver pin 32.
  • a bow-shaped lever 4 with its two legs 40 is attached to both pins 2021, 2031 and to the driver pin 32.
  • the lever 4 is provided in the region of its legs 40 with a first slot 401 for the pin 2021 or pin 2031 and with a second slot 402 for the driver pin 32. Both elongated holes 401, 402 are aligned one behind the other.
  • a guide strip 2022 is also formed on the top surface 202.
  • a guide strip 2032 is formed on the bottom surface 203 - not visible here.
  • Both guide strips 2022, 2032 serve to guide the bow-shaped lever 4, which has 40 lugs 403 in the inner region of its legs, which bear non-positively on the outer contour of the guide strips 2022, 2032.
  • the pressing force is generated by means of a compression spring 43, which is arranged between the pins 2021 or 2031 and the outer end of the elongated hole 401.
  • the bow-shaped lever 4 carries a sealing cap 5 in an articulated manner in the middle of the connecting piece 41 between the legs 40.
  • eyes 411 are formed on the connecting piece 41 for receiving an axis 42.
  • On the axis 42 a hook-shaped lever and a spring 63 are rotatably arranged.
  • the spring 63 is supported on the one hand on the connecting piece 41 and on the other hand on the lever 6, see also FIG. 4.
  • the lever 6 carries at its point of rotation opposite end a wiper lip 62 and is provided at the corners of the front edge with lugs 61 which are slightly shorter than the width of the wiper lip 62.
  • the lever 6 is pressed by the spring 63 against the front surface 201 such that the lugs 61 on the front surface rest and the wiper lip 62 is bent, see also detail Fig. 3rd Due to the overlying lugs 61, the wiper lip 62 always has the same curvature and thus a constant contact pressure thereof.
  • the ink print head 2 contains three ink print modules 21 and a cleaning module 22, which is arranged transversely under the title print modules 21; otherwise conditions are analogous to those in FIG. 1.
  • the sealing cap 5 is removed here. As a result, a universal joint 44 is clearly visible, which is fastened in the connecting piece 41 of the bow-shaped lever 4 and is used for the articulated connection thereof to the sealing cap 5.
  • the drive 9 for the gear 3 and thus via the bow-shaped lever 4, the universal joint 44, the coupling to the sealing cap 5 is shown schematically.
  • the drive 9 can consist of an actuator with a gear.
  • the connection of the ink print head 2 or the cleaning module 22 can be seen via a connecting hose 227 to an external suction pump 7.
  • the suction pump 7 is in turn connected via a hose 70 to a suction tank 8, which can be exchangeable.
  • the first kink 20221 in the guide strip 2022 serves for the defined locking of the nose 403 of the bow-shaped lever 4.
  • the sealing cap 5 is pulled by the spring 43 against the front surface 201 in this end position.
  • FIG. 4 shows the situation when the sealing cap 5 is pivoted in front of the front surface 201.
  • the second kink 20222 in the guide strip 2022 for the other end position can be clearly seen here, as can the suction openings 2230 in the side surface 204 of the housing 20 of the ink print head 2.
  • FIG. 5 the conditions according to FIG. 4 inside the ink print head 2 are disclosed by the angular section.
  • Three suction channels 222 run from the front side 220 - see also FIG. 1 - of the Cleaning module 22 to the exit.
  • Three further suction channels 223 open on the one hand with the suction openings 2230 in the side surface 204 of the ink print head 2 and on the other hand in a common connecting channel 225 which leads to a suction pump 7 which cannot be recognized.
  • the nozzle openings 211 of the ink pressure modules 21 are covered by the sealing cap 5 with the suction pad 52.
  • the suction pad 52 is mounted in a seal 51 and this in turn is mounted in a trough 53 which is attached to an end plate 54 in which the universal joint 44 engages.
  • the lever 6 with the wiper lip 62 is omitted for reasons of clarity. 6 shows the ink print head 2 with the sealing cap 5 pivoted into the second end position.
  • the nose 403 of the lever 4 is in this case latched into the second kink 20222 of the guide strip 2022 and the sealing cap 5 lies against the side surface 204.
  • the bow-shaped lever 4 slides with its nose 403 onto the outer contour when moving out of the bevels of the kinks 20221 or 22222 and the sealing cap 5 is lifted off the ink print head 2, consequently avoiding grinding on the surfaces 201 and 204, respectively .
  • FIG. 7 shows a cleaning module 22, the suction channels 222 opening on the front are combined by a common connecting channel 224, in which a suction pump in the form of a microstructure pump 226 is integrated. Only a hose 70 to the suction tank 8 is then required on the output side. Analogously, the laterally opening suction channels are combined to form a common connecting channel 225, in which a microstructure pump 226 is also integrated.
  • the structure of the sealing cap 5 is illustrated in FIG. 8.
  • the suction pad 52 is adapted to the rows of nozzles 211, see also FIG. 2, and is provided with grooves 520 for this purpose, so that direct contact is avoided.
  • the suction pad 52 is adapted to the structure of the seal 511, which is provided with chambers 510.
  • a chamber 510 is assigned to each ink pressure module 21 and each suction channel opening at the front. From the bottom of each chamber 510, an opening 511 leads through an associated opening 531 into the trough 53 receiving the seal 51 to connecting channels 541.
  • the connecting channels 541 are in the End plate 54 is molded in such a way that a connection is established between the part of the sealing cap 5 assigned to the ink ejection area and the part of the sealing cap 5 assigned to the ink suction area.
  • the tub 53 and the end plate 54 can be combined into one part.
