Definitions

  • the invention relates to a drop generator in series arranged nozzles, which are used to eject drop sequences a piezoelectric bending transducer is assigned (Piezo bending transducer drop-on-demand printhead) and one Method for controlling a piezo bending transducer drop-on-demand Printhead.
  • a conventional piezo bending transducer drop-on-demand printhead is known from DE 25 27 647 C3.
  • Piezo bending transducers are parallel to the nozzle plate in the form of an elongated tongue clamped on one side, so-called piezo-tongue transducers, in parallel in a row arranged side by side in such a way that their not clamped free ends face each one of the nozzles.
  • Piezo bending transducer is designed as a piezo bimorph, the one parallel to the nozzle plate or perpendicular to the nozzles has extending bending axis.
  • the piezo tongue For ejecting a drop the piezo tongue is bent by applying a voltage, so that the free end moves away from the associated nozzle. The voltage is switched off and the free end snaps shut the nozzle and pushes an amount of liquid through the nozzle, so that a drop is expelled.
  • the nozzles face away from the piezo bending transducers
  • Side of the nozzle plate has a circular cross section with one of the desired drop shape dependent diameter.
  • the side facing piezo bending transducers expands Nozzle funnel-shaped, but not rotationally symmetrical, but only in the direction parallel to the piezo bending transducers.
  • the nozzle has a direction perpendicular to the piezo bending transducers a constant width, so that the nozzles lie close together can be arranged.
  • the invention is based on the problem of a Piezo-bending transducer drop-on-demand print head with high resolution to create that with little manufacturing and assembly costs is producible and works without crosstalk.
  • the object is achieved with a method for Control of a piezo bending transducer drop-on-demand printhead with a nozzle plate with nozzles arranged in series, which one piezo bending transducer is assigned, each of the Piezo bending transducer with a desired print image corresponding sequence of one drop ejection movement each causing triggering pulses is applied. Every trigger pulse each is assigned to that triggered by the trigger pulse Piezo bending transducers neighboring piezo bending transducers with one this deflecting compensation pulse is applied.
  • the deflection of the neighboring piezo bending transducer by the Compensation pulse causes locally at the neighboring Nozzle associated with piezo bending transducers fluid movement.
  • This Fluid movement counteracts the fluid movement that occurs due to the trigger pulse and the movement of the triggered Piezobiegewandlers directly on the neighboring Piezo bending transducer adjusts the nozzle.
  • the Fluid movements compensate each other completely or partially. A drop of droplets on the neighboring one Nozzle associated with piezo bending transducer (neighboring nozzle) does not come conditions. Falsification of the printed image is prevented. The adverse effects of crosstalk are thus switched off.
  • adjacent piezo bending transducers can be so narrow be arranged side by side as it is the nozzle width allowed. It can therefore be a very high printhead Resolution can be achieved.
  • the narrow gap between the piezo bending transducer and the conventionally provided partitions are eliminated. During one Recess or reset movement of the piezo bending transducer can thus the flow of hydraulic fluid past the side the piezo bending transducer faster. Another Droplet ejection is thus shorter in time previous possible. The print frequency can be increased.
  • the piezo bending transducers with Trigger pulses are applied, the deflection of the Cause piezo bending transducer to the assigned nozzle.
  • the piezo bending transducers with triggering pulses are preferred applied, the deflection of the piezo bending transducer cause the associated nozzle away.
  • the real one Drop ejection movement of the piezo bending transducer then consists of the snap back of the piezo structure due to the during the Action of the trigger pulse and the associated Deflection built-up mechanical tension. Such Backward movement is generally faster than that Deflection movement.
  • Each of the adjacent piezo bending transducers is preferred a compensation pulse compared to the trigger pulse lower amplitude applied. This ensures that not due to the compensation pulse, either when deflecting or when moving backwards neighboring piezo bending transducer, a drop ejection at the Adjusts neighboring nozzle. It also prevents the Fluid movement so much energy is withdrawn that it is at the triggered nozzle no longer associated piezo bending transducer a drop of drop comes.
  • A is preferred Compensation pulse with an amplitude of 10 to 40%, further preferably one third of the amplitude of the trigger pulse upset.
  • the adjacent piezo bending transducers with a Compensation pulse compared to the trigger pulse shorter duration.
  • a shorter pulse duration can as well as with a lower amplitude of the applied Voltage can be achieved that the deflection amplitude of the Piezobiegewandlers at the compensation pulse is less than at the trigger pulse. This can also make it more undesirable Drop ejection from the neighboring nozzle and undesirably higher fluid mechanical energy withdrawal can be avoided.
  • the shorter pulse duration has the Advantage that the piezo bending transducer both in the trigger pulses as well as with the compensation pulses with one and the same Voltage can be operated to which the piezo bending transducer is designed.
  • a shorter pulse duration can also be used easy to implement in terms of control technology.
  • the adjacent piezo bending transducers are preferred in each case delayed after the assigned trigger pulse with the Compensation pulse applied. This ensures that the fluid movement due to the trigger pulse and the Fluid movement due to the compensation pulse in time largely overlap and each other particularly well compensate.
  • a time delay of 60 is preferred up to 100 microseconds, particularly preferably one of 80 Microseconds.
  • a Compensation pulse is applied, of which the neighboring Piezo bending transducer deflected in the opposite direction becomes like the triggered piezo bending transducer.
  • This can be done either a compensation pulse opposite to the trigger pulse Polarity. Or the other active location a bimorph or trimorph is applied.
  • the piezo-bending transducers triggered are preferred neighboring piezo bending transducers, however, if they have two triggered piezo bending transducers are adjacent, with a Compensation pulse of greater amplitude applied than if it are only adjacent to a triggered piezo bending transducer. This ensures that there is adequate compensation the fluid movement caused by the trigger pulse in each Trigger constellation occurs.
  • the piezo bending transducers in three groups at different times with trigger pulses are, with every third piezo bending transducer in the Series of piezo bending transducers belonging to the same group.
  • the Piezo bending transducers in two groups at different times Trigger pulses acted upon, adjacent to each other Piezo bending transducers belong to different groups.
  • the Print speed can be increased even further.
  • the trigger pulses of different strengths ensure that even at simultaneous triggering of neighboring Piezo bending transducers deliver even drops from all Nozzles is reached.
  • the piezo bending transducers if one of the neighboring piezo bending transducers also is triggered with a trigger pulse of lower amplitude acts as if none of the neighboring Piezo bending transducer is also triggered, and with a Trigger pulse of even lower amplitude applied when both neighboring piezo bending transducers are also triggered become.
  • the compensation pulses as Rectangular signals are provided.
  • the neighboring piezo bending transducers Preferably with compensation pulses with a gentle falling edge. This will achieved that due to the movement of the neighboring Piezo bending transducer towards the neighboring nozzle, i.e. depending on Polarity either at the deflection due to the Compensation pulse or when jumping back after action of the compensation pulse, no droplet ejection at the neighboring nozzle sets, but a gentle decay of the flow movement is achieved.
  • a Method for controlling a piezo bending transducer drop-on-demand Printhead with a nozzle plate arranged in series Nozzles, each of which is assigned a piezo bending transducer proposed, each of the piezo bending transducers with a sequence of one desired print image Trigger pulses causing drop ejection movement and each trigger pulse is assigned to everyone with it applied piezo bending transducers adjacent piezo bending transducers is applied with a closing control pulse, of which the Piezo bending transducer deflected towards the associated nozzle and is held there for a period during the drop ejection.
  • the neighboring piezo bending transducers with the Closing control pulse timed to the assigned trigger pulse acted upon previously or simultaneously. In this way it is ensured that the foreclosure when the Drop-ejecting movement of the trigger pulse applied piezo bending transducer has already occurred.
  • the adjacent piezo bending transducers can also be used a closing control pulse are applied, the Amplitude that comes close to a trigger pulse. To be favoured them with a close control pulse of an amplitude acted on, the maximum one sixth, the amplitude of the Trigger pulse is.
  • This enables the use of Piezo bending transducers of two-pole type, i.e. Piezobimorph with passive position or monomorph. Since the trigger pulse the Piezo bending transducers are usually deflected away from the nozzle Tripping pulse and closing control pulse each other opposed. Two-pole piezo bending transducers can actually only in one direction, namely its preferred direction be deflected. If the amplitude is low, it is also two-pole piezo bending transducers a deflection against the Preferred direction possible.
  • the Compensation pulse is individual to the individual Piezo bending transducer adapted. This way, too existing manufacturing inaccuracies Drop discharge on all nozzles or piezo bending transducers be ensured. If the trimming process is not only with individual trigger pulses but with pulse combinations, i.e. simultaneous triggering of several piezo bending transducers different constellations can be carried out interactions of manufacturing or Material inaccuracies of several piezo bending transducers be worn.
  • the measurements can be carried out within the Trimming process with one of the piezo bending transducers independent device.
  • the piezo bending transducers as sensors used by voltages that result from triggering a Piezo bending transducer, the fluid movement caused thereby and the deflection of the neighboring piezo bending transducers in them be induced, measured and to optimize the Drop ejection or crosstalk behavior can be evaluated.
  • This allows and without additional equipment thus inexpensively determine the crosstalk behavior. Thereby, that effects can be recorded in the printhead itself can Crosstalk behavior can be determined particularly precisely.
  • the piezo-bending transducers triggered are preferred neighboring piezo bending transducers during operation Compensation pulses or closing control pulses are applied, determined for the amplitude, duration and / or time delay be caused by tensions caused by the triggering of a Piezo bending transducer, the fluid movement caused thereby and the deflection of the neighboring piezo bending transducers in them be induced, measured and processed. So one serves Adjacent piezo bending transducer after application of a trigger pulse initially as a sensor. The recorded data are evaluated and Amlitude, duration and / or time delay of the optimal Compensation pulse are determined.
  • the ongoing adjustment when operating the piezo bending transducer drop-on-demand Print head can be used instead of the invention Trimming or in addition to trimming before commissioning.
