Definitions

  • the invention relates to a device for refilling a printhead of an inkjet printer according to the preamble of claim 1.
  • the printhead can be refilled by hand through a bellows-like refill container, as is known, for example, from WO 92/20 577.
  • the refill container has a hollow needle which is inserted through a ventilation opening in the housing of the printhead and thereby inserted into the ink supply space.
  • the refill container described there is basically suitable for refilling printheads, a number of problems arise in practical handling. For example, it cannot be prevented that ink emerges from the nozzle plate during the filling process, associated with the risk of contamination.
  • a refillable cartridge which can be placed on the cannula empties into the ink reservoir after removal of a cap which closes it, so that the filling process runs automatically without further action.
  • Various sealing elements largely prevent unintentional leakage of ink from the nozzle plate and the ventilation opening.
  • Devices have also become known with the aid of which the filling process can run at least partially automatically, for example from EP 0 603 910 A1, from which the invention is based. It has a holder in which the printhead to be filled can be inserted.
  • the ink supply is located in an ink tank, which can be connected to the ventilation opening of the print head in a sealed manner via a line and a coupling piece.
  • the apparatus further includes a pump, in the form of a double-acting piston pump, which is connected at one end to the ink tank and serves to convey ink from the ink tank into the ink supply chamber of the printhead.
  • the pump is connected in a sealed manner to the nozzle plate of the print head via a further line and a coupling piece, so that a negative pressure in the region of the nozzle plate and thus can be generated inside the ink supply chamber of the printhead.
  • the double action of the piston pump now consists in that when the piston is displaced, overpressure is generated on one side, which conveys ink from the ink tank into the ink reservoir of the printhead. At the same time, a negative pressure is generated on the opposite side of the piston, which partially evacuates the ink supply space.
  • a series of valves ensures that the return movement of the piston can take place largely without resistance, without reversing the pressure conditions.
  • Additional valves can be provided at different positions on a case-by-case basis in order to vary the relation and the temporal course of partial vacuum in the ink supply space on the one hand and the delivery pressure of the ink to be supplied on the other and to optimally adjust them to predetermined conditions.
  • all variants are based on the basic principle of generating a partial vacuum in the ink supply space, at least in the initial phase of the filling process, in order to accelerate the penetration speed of the ink, and thus the speed of the refilling process as such.
  • This is of outstanding importance in the printheads described there, since their ink supply chambers are filled with an open-pore foam material as a recording medium for ink, which considerably delays the penetration rate of the ink under normal printing conditions. This deficiency is remedied by at least partially lowering the pressure in the ink supply space.
  • the devices described above can at least partially simplify the filling process, manual intervention by an operator is nevertheless required.
  • the pump In the case of the first-mentioned device, the pump must be operated by a hand lever, and it is also necessary to observe the refilling process and to end it by hand as soon as excess ink escapes into the collecting container. This also applies analogously to the device known from EP 0 509 687 A2, which expressly describes the manual closing of valves by an operator.
  • the invention was therefore based on the problem of developing a device of the type mentioned at the outset in such a way that the refilling of a printhead removed from the printer was carried out directly by the user and largely without manual intervention by the operator, i.e. can be carried out automatically.
  • the device should be simple and inexpensive to set up and operate safely in accordance with the intended field of application in the home or in smaller offices.
  • the invention is based on the idea of ink over one itself pumping as an aeration hole or aeration screw into the ink reservoir of the printhead under increased pressure and to let the air displaced thereby escape through the outlet openings of the nozzle plate.
  • the holder for the printhead is designed so that the printhead can be positioned with the nozzle plate essentially pointing upwards.
  • the air displaced by the inflowing ink can escape directly upwards, so that foaming or blistering is excluded even with rapid ink supply under high pressure.
  • the displaced air can be largely pushed through the outlet openings of the nozzle plate above the ink level before the rising ink level.
  • the maximum fill level is reached when the ink level reaches the outlet openings of the nozzle plate. Positioning with the nozzle plate pointing upwards ensures that the ink supply space is completely filled in this state and practically the entire volume can be used again.
  • a filling device can be implemented with comparatively little design effort, since the evacuation of the ink supply space can be completely dispensed with. This also means no loss of functionality, since it is possible to work with a comparatively high delivery pressure. Furthermore, the air displaced through the outlet openings of the nozzle plate provides the desired cleaning effect in the region of the nozzle plate, since the air flow escaping at high speed entrains paper dust which has accumulated in the region of the outlet openings. This reliably prevents dust particles from penetrating into the inlet openings and clogging them, as occurs in the conceivable alternative, in which ink is supplied through the nozzle plate.
  • the use of the ventilation opening or the ventilation screw as a supply opening for the ink is not least of all advantageous because it is easily accessible from the outside of the housing of the Printhead are accessible. This eliminates the need for preparatory measures to expose any filling openings that may be present, such as the pressing in of balls serving as closure elements.
  • the print head is ready for use immediately after filling.
  • a subsequent preparation step in the form of the priming described at the outset is omitted because, due to the positioning of the print head during the filling process, any space that may be between the recording medium and the nozzle plate is filled with ink without further action and the air therein is displaced.
  • the filling process can be carried out fully automatically by means of control electronics.
  • the ink is fed into the ink reservoir until the desired filling level is reached.
  • the direction of delivery of the pump is then reversed so that the delivery pressure can be reduced and, if necessary, a predetermined vacuum can be established in the ink supply chamber.
  • the reduction of the delivery pressure by reversing the direction of delivery accelerates the pressure equalization, so that the print head can be removed from the holder practically immediately after the desired filling state has been reached, there being no risk of contamination from residual amounts of ink present under the delivery pressure.
  • the reversal of the conveying direction also makes it possible to produce a negative pressure required for certain printheads in the ink supply space, without which the functionality of the refilled printhead is not or only to a limited extent.
  • an ink tank is therefore provided, which is connected to the via a line and a coupling piece Ventilation opening can be connected in a sealed manner, so that a fluid connection can be established between the ink tank and the ink supply space.
  • a pump with reversible delivery direction is switched on, which is actuated fully automatically in the desired manner via the control electronics.
  • a collecting container is also provided which can be connected to the nozzle plate in a sealed manner via a line and a coupling piece, so that ink droplets which are entrained by the air escaping from the nozzle area during the filling process can be collected in a targeted manner and there is no risk of contamination.
  • ink droplets often adhere to the nozzle plate itself or in immediately adjacent areas inside the ink supply space on wall areas which are swept by the displaced air, so that the droplets are inevitably entrained in the air flow.
  • the ink supply space of the printhead is thus sealed and integrated into a line system during the period of the filling process, in which fluid flows are generated and controlled in a fully automatic manner, and at the same time unintentional leakage of ink is avoided.
  • the device therefore enables the automatic refilling of print heads without manual intervention.
  • a signal transmitter is installed in the line between the nozzle plate and the collecting container, which responds as soon as ink emerges from the nozzle plate and is present in the line. This is the criterion for the ink head of the printhead to be completely full, so that the pump can be stopped.
  • the signal generator is connected to the control electronics, which act on the pump in the manner described above. It goes without saying that the signal transmitter is designed such that it does not detect individual ink droplets entrained by the escaping air, but rather only responds when there is a continuous liquid column in the line just above the outlet openings of the nozzle plate.
  • a signal generator can be installed in the line between the ink tank and the vent, in the section between the pump and the vent. At the point mentioned, it measures the pressure prevailing in the delivery line for the ink before it enters the printhead.
  • the switch-off or reversal criterion for the pump is the sudden pressure rise that occurs as a result of the throttling effect of the outlet openings of the nozzle plate as soon as the ink level is present on the nozzle plate. Because of their small diameter, the outlet openings represent a throttling point for the ink, which suddenly offers resistance to the progressing liquid front of the rising ink level. The pressure surge associated with this continues quickly against the direction of the ink and is detected by the signal transmitter.
  • the signal generator is connected to the control electronics, which act on the pump in the manner described above. In contrast to the liquid-detecting sensor described above, this signal transmitter is more cost-effective as a comparatively simple pressure sensor.
  • the specified fill level can be exactly maintained so that printheads that still have residual ink in the ink supply chamber can be refilled without the risk of overfilling. Furthermore, fluctuations in the delivery rate of the ink are irrelevant, since the pump is switched off or reversed exactly at the point in time at which the ink supply space has reached the desired filling level.
  • Further sensors are preferably provided, which are used to monitor and / or control the filling process. It deals are liquid or flow sensors which are known per se and are integrated at various points in the lines. For example, a sensor of this type is installed in the line between the ink tank and the pump in order to monitor the ink flow. This ensures that no air is pumped into the printhead's ink reservoir if the ink tank is exhausted. In such a case, the control electronics ensure that the pump is stopped immediately and the reversal of the conveyor is initiated. This is necessary so that the print head can be easily removed and inserted into the printer even if the ink supply space is not completely filled.
  • a display element for example in the form of an LED or LCD, is preferably activated at the same time or an acoustic signal is triggered in order to draw attention to this operating state.
  • sensors are preferably installed that take advantage of the electrical conductivity of the inks used.
  • a resistance measurement can be used to easily determine between two measuring points whether ink is present or not.
  • this sensor also triggers the reversal of the delivery direction of the pump.
  • the signals generated by the sensors can be used at the same time to display the respective operating states.
  • LEDs are preferably used, which can have different flashing frequencies or different colors to identify various operating states. These can also be coupled with acoustic signals.
  • a in the feed line in particular in the section between the pump and the ventilation opening another sensor is installed that monitors the pressure in this section. This is necessary in order to prevent an inadmissible pressure increase in the event of a blocked ventilation opening or ventilation screw or blocked outlet openings in the nozzle plate area. Such an increase in pressure could, on the one hand, lead to damage or destruction of important components, or could result in heavy soiling due to sudden leakage of ink at the moment the blockage was broken. In this case too, the pump must be reversed and the operating status must be displayed.
  • the lines are flexible hoses, in particular made of silicone, polytetrafluoroethylene (PTFE) or polyethylene (PE).
  • PTFE polytetrafluoroethylene
  • PE polyethylene
  • Such materials also open up the possibility of using a so-called peristaltic pump as a pump, in which, in contrast to the other types of pumps, no dirt or abrasion particles can come into contact with the ink. Such particles should never be put into the ink, as they can impair the function of the print head.
  • these hoses offer the possibility of monitoring the blocking states described above by clogged outlet openings and the like by monitoring the hose thickness and / or the hose diameter.
  • a pressure build-up leads to a widening of the hose and can thus be detected by simple means such as optical sensors or the like. It is therefore not necessary to install a sensor in the line itself, rather it can be arranged outside, ie outside the ink flow.
  • the coupling pieces for the ventilation opening and for the nozzle plate, which are attached to the ends of the lines, are preferably formed in one piece, namely when the ventilation opening and the nozzle plate are arranged adjacent to one another in the printhead type to be filled.
  • the seal between the coupling piece and printhead can be achieved by a resilient portion, so that the transition from the line to the ventilation opening or to the nozzle plate is made fluid-tight for the duration of the filling process by pressing the coupling piece onto the adjacent housing wall.
  • the ink tank preferably consists of flexible material, namely a plastic bag, which is accommodated in a dimensionally stable housing.
  • the housing can be designed to be foldable, so that the ink supply contained therein can be checked without problems.
  • refilling the ink tank it is an advantage if it is designed to be replaceable. This is to be seen in terms of an optimal and user-friendly operation, whereby the ink tank as such only needs to be replaced at certain intervals by a new one. Depending on the planned replacement interval, the volume of the ink tank itself can be varied within further limits.
  • the ink tank must also be designed so that it can easily receive the returned ink or the ink-air mixture when the pump is in the opposite direction.
  • the collecting container is advantageously at least partially filled with absorbent material, preferably with felt, sponge or a fleece, so that the ink droplets emerging from the area of the nozzle plate and the residual ink which overshoots at the end of the filling process can be safely absorbed.
  • absorbent material preferably with felt, sponge or a fleece
  • the collecting container and / or the absorbent material is preferably exchangeable. In terms of simple handling, it makes sense to completely replace the collecting container including the absorbent material contained therein.
  • the nozzle plate must face upwards in order to allow the displaced air to escape during the filling process.
  • the nozzle plate is arranged on a step-shaped section, so that the filling process can still proceed satisfactorily even when the print head is pivoted relative to the vertical.
  • the arrangement can be chosen so that the printhead is inclined up to a maximum of 80 ° from the vertical.
  • the holder can also be designed to be pivotable in such a way that the print head has a nozzle plate pointing downwards, i.e. can be used in a position which corresponds to that in the printer itself, the holder being able to be pivoted into the filling position after insertion.
  • Adapters can be inserted into the holder in order to enable adaptation to different printheads.
  • the holder itself can also be designed as an adapter, provided that it is designed to be exchangeable.
  • the device is therefore particularly suitable for smaller offices which have different printers or different types of print heads.
  • the specific design of the device is largely freely selectable. It is preferably constructed from individual modules in the manner of a modular system, so that individual adaptation to different requirements is possible. This also refers to the external design that can be chosen as desired.
  • the device into a housing that can be closed by a cover.
  • the cover is coupled to the control electronics via a sensor in such a way that opening during the filling process is not possible, or the filling process is interrupted immediately if the cover should be opened. Additional measures are also possible to prevent start-up, for example, if no printhead is inserted or another component is not working properly.
