Definitions

  • the invention relates to a combination of at least one inkjet printhead and a device for free spraying of an inkjet printhead according to the preamble of claim 1.
  • the invention is used in microprocessor-controlled printing devices and is suitable for franking machines and other mail processing devices.
  • the inkjet print head is moved during printing and on the one hand cleaned and maintained in a wrongspositlon and on the other hand held in a printing pause in print readiness and can be regularly sprayed free.
  • An apparatus for the free spraying of an ink jet print head of an ink printing system in which the printed matter or mail pieces are transported past a fixed during printing ink jet print head and wherein the Ink printhead is arranged stationary pivotally behind a guide plate, and with the addition of the usual functions, such as wiping and sealing, a free spraying during the transport of the printed material or mail items is possible.
  • a free spray position near the printing position allows the elimination of the longer travel times from a printing position to a cleaning and sealing position.
  • a compact transport device for mail pieces is needed, which should not be polluted by the free spraying.
  • at least one ink cartridge is arranged opposite to the direction of gravity over a printing window in the z-direction of a Cartesian coordinate system.
  • at least one ink jet printhead ejects ink droplets opposite to the z direction in the direction of gravity, which fly through the printing window.
  • the printing window is arranged on the edge of a conveyor belt in the y-direction in a housing part, wherein the conveyor belt transports a flat good to be printed on the edge during printing in the transport direction x on the at least one print head over.
  • the FR-A-2768078 is the closest prior art of the invention according to claim 1 and shows a combination of an ink jet printing device and a maintenance station.
  • the inkjet printer has two inkjet printheads.
  • each ink jet print head is associated with a shaft-like protective cap which is connected to a suction device for sucking ink.
  • the shaft-like caps are arranged on a shaft support, which is adjustable by means of a motor-driven cam against a spring force from a first position in which the protective caps on the printheads through openings in the feed table, and a second position in which the protective caps of the inkjet printheads are removed and clear the way for a piece of mail to be printed.
  • the US 2006/001696 A1 also shows an ink jet printer with an ink jet printhead disposed above a support surface for the print material and a protective device for the ink jet printhead disposed below the running surface with a cover cap which is adjustable by means of an adjusting device through the running surface between a cover position and a release position.
  • the invention has for its object to develop a combination of at least one ink jet printhead and a device for free spraying of an ink jet printhead, which uses a free-jet slot to reduce the ink contamination in a postage meter.
  • the device consists of a feed table with a counter to a spring force deflectable shaft support, which is equipped with at least one free-jet slot, which is arranged opposite at least one ink-jet printhead.
  • a free-jet slot is provided, which is molded onto a resilient shaft support, which is coupled to at least one actuating element and arranged in the transport path below the at least one inkjet printhead, wherein the feed table includes an opening for the actuating element.
  • the shaft carrier is shaped in such a way that the at least one free-standing shaft is deflected out of the transport path by the inlet of a supplied mail piece.
  • a free-jet shaft is used for each inkjet printhead.
  • one or two free-injection wells are used, which are coupled to a resilient shaft support with at least one actuating element and are arranged in the transport path below the printheads. Due to the spring action, free-standing wells are brought close to the ink-jet printheads, so that all ink jets are inside the free-fall wells.
  • the squeeze position is the print position. The inkjet printheads remain stationary during printing in the printing position and only the at least one free-jet pit is moved away from the ink-jet printhead. No separate engine is required for this.
  • the actuator equipped with a guide cam is actuated and the tray carrier with the free-injection chutes is moved downwardly against a spring force from the mail piece transport path.
  • a printing of the mail pieces can be realized.
  • the mailpiece pass is monitored by sensors. After the mailpiece pass, the well carrier with the free-injection wells is moved back to the position below the ink jet print heads due to the spring action to allow further free syringes as soon as the aforementioned sensors notify a controller that the mail piece transport path is free of mail pieces. Then, the inkjet printheads are appropriately driven to initiate the free-spraying.
  • the advantage is that it allows for immediate free spattering in the print position without having to advance the inkjet printheads.
  • Another advantage is that no separate drive is needed to move the tray carrier.
  • the resilient shaft support is rotatably mounted on one side on a rotation axis underneath a mailpiece feed table and has at least one free-injection shaft at the other end, which projects through an associated opening in the mailpiece feed table in the z-direction.
