Definitions

  • the invention relates to an ink jet recording head having a pressurized ink chamber with at least one ink nozzle, which is closed by a movable valve body, and a piezoelectric valve actuator driving the valve body for lifting movements, which is electrically connected to a drive means.
  • Such ink-jet recording heads are used to print characters and numbers on the surfaces moved past them.
  • a plurality of ink nozzles are provided in an ink chamber, which are selectively actuated by a controller to briefly open the respectively driven nozzle.
  • a short jet of ink is ejected from the ink nozzle, which generates a dot on the surface to be printed.
  • ink-jet recording head EP 0 445 137
  • hinged magnets whose armature are each in drive connection with the associated valve body.
  • the mass formed essentially by the armature of the folding magnet must be accelerated and decelerated during each valve actuation process.
  • the object of the invention is therefore to provide an ink-jet recording head of the type mentioned in such a way that it can be operated smoothly under the working speeds required in practice.
  • valve body is held by a closing spring in its closed position and with a preferably sealed from the ink chamber movably led out drawbar is in drive connection that acts on the drawbar mindestes a curved spring strip at its end opposite the ink chamber is supported, that the pull rod is under tension bias of a tension spring and that on the spring strip at least one piezoelectric element is applied, which can be controlled by the driving device to Dehn- or contraction movements.
  • piezo elements are used, in particular piezo elements based on films are suitable.
  • piezoelectric elements based on fibers or strips
  • MFC piezo elements micro-fiber composite piezoelectric element
  • high-performance piezoelectric elements are available in the form of flat piezoelectric elements, they can not be used directly for actuating valves on ink-jet writing heads because of their design. Only through the connection with at least one curved spring strip, on which a planar piezoelectric element is applied on one side, creates a valve actuator, which allows a very high performance and operating speed in a very small footprint, to be used in an inkjet recording head. In particular, the functionality of the valve actuator remains unrestricted even at high operating frequency over a long period.
  • a piezoelectric element which is under compressive prestressing and excited only to stretch movements, is applied.
  • it may also be provided to apply in each case to the curvature outside of the spring strip a piezoelectric element which can be excited to give contraction movements. It is particularly advantageous to apply the piezo elements on both sides of the spring strip. As a result, a particularly high actuation force is achieved.
  • the valve remote end of the tie rod engages only one provided with a piezoelectric element, curved spring strip.
  • the masses to be moved are relatively small, so that a high operating frequency is achieved.
  • an embodiment is possible in which attack at the valve distal end of the pull rod two curved in the opposite direction spring strip, which are supported at their valve-side ends against the Tintenkamme r, and wherein the piezo elements of the two spring strips controlled by the driving device together to the movements are. Due to the symmetrical structure, a symmetrical force attack on the pull rod is achieved even without a guide device.
  • the pull rod may extend at its valve remote end through a bore of an upper clamping block and carry on a threaded portion of an adjusting nut, which allows adjustment of the bias. Valve side, the tie rod extends through a bore of a lower clamping block, in which the end of the spring strip or the ends of the two spring strips is or are received.
  • the pull rod is connected directly to the valve body according to a first embodiment of the invention. This gives an immediate power transfer from the pull rod to the valve body.
  • This embodiment is particularly suitable when there is only a single ink nozzle or when there is a sufficient gap between them in the case of a plurality of ink nozzles.
  • the pull rod via an actuating lever is in driving connection with a valve connecting rod connected to the valve closing body.
  • This embodiment makes it possible to arrange the valve actuators staggered on both sides of the ink chamber, so that also relatively closely juxtaposed ink nozzles can be achieved.
  • the in the Fig. 1 and 2 illustrated inkjet printhead serves on a in Fig. 2 only indicated area 1 characters and numbers to be printed while this area 1 is moved along the ink jet recording head.
  • the inkjet recording head to a writing ink filled, pressurized ink chamber 2, which is supplied via an ink line 3 with ink.
  • a writing ink filled, pressurized ink chamber 2 which is supplied via an ink line 3 with ink.
  • ink nozzles 5 are arranged, wherein in Fig. 1 only one of these ink nozzles 5 is shown.
  • Each ink nozzle 5 is closed by a valve body 6 which is driven to controlled strokes.
  • the valve body 6 is pressed by a closing spring 7 designed as a compression spring in the closed position of the valve is connected via a guided out of the ink chamber 2 pull rod 8 with a valve actuator 9.
  • the pull rod 8 may consist of a wire, a thin pull rope or a stranded stranded wire.
  • the pull rod 8 extends through the valve actuator 9 and carries at its upper end remote from the valve on a threaded portion 10 an adjusting nut 11.
  • the pull rod 8 extends at its valve distal end through a bore 12 of an upper Clamping block 13.
  • At the valve remote end of the pull rod 8 engage in the opposite direction convexly curved spring strips 14, which consist for example of spring steel. The upper ends of the two spring strips 14 are received in the upper clamping block 13.
  • the lower ends of the two spring strips 14 are received in a lower clamping block 15.
  • the pull rod 8 extends on the valve side through a bore 16 of the lower clamping block 15, which in the embodiment of the Fig. 1 and 2 sits directly on the ink chamber 2.
  • the lower clamping block 15 is also in a fixed position to the ink chamber. 2
  • the pull rod 8 is under tensile prestress of a tension spring.
  • a tension spring In the embodiment of the Fig. 1 and 2 forms the closing spring 7, which presses on the valve body 6, at the same time the tension spring of the pull rod eighth
  • the two curved spring strips 14 each carry a piezoelectric element 17 on the inside of the bulge.
  • These are preferably flat piezoelectric elements, with piezo-elements based on films in particular being suitable.
  • the use of piezoelectric elements based on fibers or strips is possible.
  • Both piezo elements 17 are connected by an electrical drive device 18 to Dehnterrorismen controllable.
  • the two piezo elements 17 are due to the bias of the valve actuator 9 and the resulting curvature of the spring elements 14 on their concave Völbungsinnencharge under a mechanical compression bias. They are electrically driven by the drive means 18 only in such a way that they perform an expansion movement.
  • a further planar piezoelectric element 17a may be applied, which is electrically connected so that it is only excited to contraction movements and therefore exerts tensile forces.
  • the drawbar 8 is connected directly to the valve body 6. Deviating from this is in the embodiment after Fig. 3 the pull rod 8 via a one-sided on the lower clamping block 15 mounted actuating lever 19 with a connected to the valve closing member 6 valve connecting rod 20 in drive connection.
  • Fig. 4 illustrated embodiment differs from the embodiment according to Fig. 1 primarily by the fact that instead of the two spring strips 14 at the valve distal end of the drawbar 8 only a single, provided with a piezo element 17, curved spring strip 14 acts.
  • the valve distal end 14a of the spring strip 14 is in this case longitudinally movably guided in a longitudinal guide device in the longitudinal direction of the drawbar 8.
  • the longitudinal guide device on a stationary guide slot 24 engages in the at least one upper longitudinal extension 25 of the spring strip 14 movable.
  • the guide slot 24 is formed on a guide plate 26 which is fastened at its one end to the clamping block 15, for example screwed and angled at the other end to a horizontal plate 27.
  • the longitudinal extensions 24 of the spring plate 14 are formed for example by the two upwards, ie in the longitudinal direction of the pull rod 8 extended side strips of the spring plate 14. A between these two longitudinal extensions 25 horizontally angled tab 28 is below the adjusting nut 11 and transmits the movements of the spring plate 14 on the pull rod 8. Since the masses to be moved in this case are relatively low, very high operating frequencies are achieved.
  • the longitudinal guide device can also be designed so that the valve distal end of the drawbar 8 is guided in the longitudinal guide device in the longitudinal direction of the drawbar movable, for example, also in a guide bore in the plate 27th
  • a spring 29, which is designed here as a compression spring.
  • the spring 29 is supported on the underside of the plate 27 and biases the spring strip 14 in the direction of movement of the pull rod 8.
  • the required bias of the piezoelectric element 17 is in this case essentially by the spring 29, so that on the one hand, the bias of the piezoelectric element 17 can be specified precisely and on the other hand, the closing spring 7 can be designed weaker.
  • Fig. 6 shows a valve actuator similar to the Fig. 4 , although in the already at Fig. 3 described manner on the camber outside of the spring strip 14 a stimulus for contraction movements planar piezoelectric element 17a is applied.
  • Fig. 7 are shown in a vertical section two immediately adjacent to each other in an ink-jet recording head arranged valve actuation devices, each having a curved spring strip 14 'and at the valve distal end of the spring strip 14' attacking tie rod 8.
  • a planar piezoelectric element 17' appli graced At the vault outside of the spring strip 14 ' is a planar piezoelectric element 17' appli graced.
  • each spring strip 14 ' is similar in the embodiment according to Fig. 6 , Deviating from this, however, the pull rod 8 extends through a passage opening 30 of the spring strip 14 'and the planar piezo element 17'. How very clear Fig. 8 can be seen, the passage opening 30 for the tie rod 8 is a valve-side end of the spring strip 14 'open longitudinal slot.
  • the implementation of the pull rod 8 through the passage opening 30 of the spring strip 14 ' allows a space-saving arrangement.
  • the distance between two adjacent tie rods 8 and thus between two adjacent ink nozzles 5 can be very tight despite relatively large peak height of the curved spring strips 14 'because the support of the valve end of each spring strip 14' - Fig. 7 shown - may lie in the vicinity of the respective adjacent tie rod 8.
  • mutual distance of the ink nozzles 5 can be selected for the efficiency of the piezoelectric valve actuator, relatively strong curvature of the spring strip 14 '.
  • Fig. 8 also shows that the spring strip 14 'is laterally constricted in its central region. This results in the central region of the spring strip 14 'an increased bending elasticity. This is favorable for the drive behavior.
  • Fig. 9 engages the end of the projecting into the valve actuator 109 pull rod 108 a curved or curved spring strip 114, which consists for example of spring steel sheet, fiber-reinforced plastic or the like, resilient material.
  • the domed spring strip 114 is attached at its valve distal (in the drawing upper) end 114a to a bow-shaped support 113, which is attached for example to the upper wall of the ink chamber 2.
  • the pull rod 108 extends in the illustrated embodiment through a bore 115 in the upper wall of the ink chamber 2 and through a bore 116 of an angled tab 117 at the valve near end 118 of the spring strip 114th
  • a extending in the direction of movement of the drawbar 8 tongue 119 at the valve near end 118 of the spring strip 114 is guided in a serving as a longitudinal guide means recess 120 in the longitudinal direction of the tie rod 108 movable.
  • the curved spring strip 114 carries in the in Fig. 9 illustrated embodiment on its curvature inside a piezoelectric element 121.
  • This is preferably a planar piezoelectric element, in particular piezoelectric elements are suitable based on film.
  • piezoelectric elements are suitable based on fibers or strips.
  • the piezoelectric element 121 is caused by a electrical drive means 122, which is indicated only schematically in the drawing, to a contraction movement controllable. As the electrically driven piezoelectric element 121 shortens, the curvature or curvature of the spring strip 114 is enhanced. As a result, a tensile force is exerted on the pull rod 108; the valve is opened. The valve closes again under the action of the closing spring 7, as soon as this tensile force is no longer effective.
  • the ink-jet recording head shown differs from the writing head Fig. 7 in that on the pull rod 108 two curved in the opposite direction spring strips 114 attack, which are each arranged as already in the example according to Fig. 9 has been described. Both spring strips 114 are attached to their valve remote ends 112 and connected at their valve-near ends 118 with each other and with the tie rod 108. A longitudinal guide device, as in Fig. 9 described omitted in this double arrangement of the spring strips 114th
  • FIG. 11 The embodiment shown differs from the exemplary embodiment Fig. 1 only in that in addition to the already described planar piezoelectric element 121 on the curvature inside of the spring strip 114, a further, planar piezoelectric element 123 is applied to the vault outside of the spring strip 114. While the piezoelectric element 121 on the inside of the dome in the manner already described by the electric drive means 122 to contraction movements is controllable, the planar piezoelectric element 123 on the vault outside of the spring strip 114 is designed so that it through the electrical control device 122 is controlled to Ausdehn movements.
  • the embodiment according to Fig. 12 differs from the execution Fig. 11 only in that here the piezoelectric element on the curvature inner side of the spring strip 114 has been omitted, so that the spring strip 114 carries only the stimulable to Ausdehn movements piezoelectric element 123 on the vault outside.
