Definitions

  • the present invention relates to the field of the treatment of mail and it relates more particularly to a device for cleaning the ink ejection nozzles of an inkjet printhead of a postage meter for mail items.
  • the present invention provides a nozzle cleaning device ink ejection which does not require the passage of these nozzles to a maintenance station and which can be implemented during their operation.
  • An object of the present invention is also to propose a simple and inexpensive device, so as to allow its installation on cheap franking machines.
  • a nozzle cleaning device ink ejection of a machine inkjet print head mail processing characterized in that it comprises a means of scraping disposed in a transport path of mail items at right of the ejection nozzles and actuated by a mail item at its advanced under the print head.
  • the scraping means which preferably comprises a wheel optionally motorized fins, is articulated between a position of scraping in which the scraping means is disposed in the path of transport of mail items and a rest position in which the scraping means is set back from this transport path.
  • means for cleaning said means scraper comprises a scraper which rubs each fin of the wheel fins.
  • the displacement of said support arm can be controlled according to the number of mail items counted by a position sensor arranged on the way of transport of the articles of mail.
  • This sensor position is advantageously arranged upstream of said means of scraping.
  • FIG. 10 is a partial view at the level of the means printing of a mail processing machine.
  • the print head 10 which conventionally comprises two printed modules 12, 14 staggered in a direction perpendicular to the direction D of advancing articles mail is mounted between two sets of drive rollers, a first series of two upstream rollers 16, 18 superimposed one of which preferably the upper roller 16, is motorized and a second series of two downstream rollers 20, 22 superimposed also one of which, preferably the upper roller 20 is motorized.
  • an upper fixed plate 24 and a lower mobile plate 26 (also called ski mobile) define a path 28 for transporting mail items 30.
  • These trays are of course perforated to the right of the ejection nozzles of ink 12A, 14A of each print module.
  • Reference 32 illustrates one of the corresponding openings (the second 34 is behind the plane cutting due to the offset of the two modules).
  • the printhead 10 is movable and can take two positions, a print position in which printing a postal imprint is possible and a rest or maintenance position in which this print head is set back from the transport path 28 at the level a maintenance station to allow nozzle cleaning ink ejection, thus prohibiting any printing of an impression PO.
  • the print head 10 is now fixed in the position printing and cleaning the ink ejection nozzles is carried out directly in that position, ie in the very course of printing process.
  • a scraper means is provided in the path 28 for transporting mail items to the nozzle of ink ejection 12A, 14A and actuated by a mailpiece 30 when of its progress under these nozzles. More specifically, this scraping means comprises two impeller wheels 38A, 38B each provided with at least one blade or blade and disposed in line with a row of nozzles 12A, 12B of a given print module, in the opening made in the trays fixed 24 and mobile 26, and whose rotation is controlled by the advance of a mail article.
  • the impeller 38A, 38B being fixed, that is to say solidary of the body of mail processing machine, it is provided a light 26A, 26B in the fixed plate 26 so as to allow the moving this tray according to the thickness of the mail to print.
  • each fin combines elasticity and rigidity effective cleaning without altering the nozzles.
  • the scraping means In order to guarantee the maintenance of the effectiveness of the scraping means, it cooperates with a means of automatic cleaning of the fins polluted by the debris from the ink ejection nozzles, formed of a scraper 40A, fixed 40B, ie integral with the machine body of mail processing, and on which will rub one after another the pale wing wheels 38A, 38B.
  • FIG. 2 illustrates an embodiment variant of FIG. which the impeller 38A, 38B is motorized by a motor 40A, 40B so that the scraping of the ejection nozzles can be carried out also between mail items, or even in the absence of articles from mail.
  • each wheel provided with at least a fin or blade is mounted on a support arm 44A, 44B pivoting around an articulation axis 46A, 46B secured to the movable plate 26, to against an elastic means, for example a spring 48A, 48B, secured to this support arm at one end and the movable plate to its other end.
  • This spring-mounted arrangement allows the cleaning of nozzles with an optimal application constraint.
  • the support arm can move between a scraping position (corresponding to the position of the first embodiment) and a rest position set back from the transport path (preferably retracted under this path and can be if necessary also clear of the nozzle spitting area) under the influence of a means of control, for example a motor or an electromagnet 50A, 50B whose the motor shaft or the corresponding control rod 52A, 52b is connected to the associated support arm.
  • a means of control for example a motor or an electromagnet 50A, 50B whose the motor shaft or the corresponding control rod 52A, 52b is connected to the associated support arm.
  • kinematics with levers and pulleys may be provided between this control means and the finned wheels.
  • the control means is actuated from a means of treatment 54 according to different parameters, the number of mail items counted by a position sensor, such as tilting lever 56, arranged on the transport path of the articles of mail upstream of the scraping means and actuated by the front of each mail item.
  • This number of mail items can be set according to the type of paper used or any other consideration, for example the country of installation of the machine. So, in this embodiment, the scraping of the nozzles is not performed when the printing of each mail item but after the passage of a number of these articles.
  • FIG. 7 illustrates a third embodiment of the invention wherein the hinge axis 46A, 46B of the support arm 44A, 44B and the control means 50A, 50B are no longer fixed on the moving plate but attached directly to the body of the processing machine mail.
  • the engine control is simplified because it is no longer necessary to compensate for the movable platen 26, the distance impeller / nozzles now being fixed.
  • FIG. 8 An alternative embodiment of FIG. 7 is illustrated in FIG. 8.
  • the control means 50A, 50B is arranged directly on the hinge axis 46A, 46B which further supports the elastic means 48A, 48B.
  • the present invention can not be limited to illustrated figures only and the person skilled in the art will be able to complete them without demonstrate inventive activity.
  • the wheel with fins may have a form of forest (or worm), each helical cutting edge corresponding to a scraping edge of a blade.
  • forest or worm
