Definitions
- the present invention relates to an ink supply tank for a Ink jet print head which can be fixedly attached in an ink jet printer with an ink reservoir attached to one of the ink jet printhead leading ink supply line is connectable, and with a Ink dispenser, the externally accessible actuators has, which with corresponding, motor-driven drive elements of the inkjet printer can be brought into operative engagement, the Ink delivery device with actuation of the actuating elements with ink Feeds excess pressure into the ink supply line.
- a central part of an inkjet printer is the inkjet printhead, the one with a corresponding mechanism relative to the printable Can be positioned and controlled by ink leakage from a Variety of fine print nozzles creates the print image.
- the continuous The printhead is supplied with ink from an ink reservoir, which holds a larger ink reservoir.
- simple black and white inkjet printers is composed of the inkjet printhead formed with the ink reservoir as a one-piece, interchangeable unit.
- a separate ink tank from the printhead with the entrances features mentioned is described, for example, in US Pat. No. 5,777,646.
- this has an attached, active ink delivery device, which serves the ink supply lines to pressurize. This is required to a continuous flow of ink in all practically occurring To ensure acceleration states.
- this is an ink dispenser in the form of a small pump, which acts as an actuator has a flexible pump bellows accessible from the outside, that of motor-driven drive cams on the printer every time actuated, that is pressed together when a print job is pending.
- This active actuation of the pump device has the advantage that it is independent from the fill level in the ink reservoir over the entire Adequate life of the ink supply tank with every print job Ink operating pressure is built up in the order of magnitude from about 0.2 to 0.3 bar.
- a major disadvantage of the known ink supply tanks with active Ink delivery is that the pump mechanism for ink delivery is off a large number of individual components. For example, one separate pumping chamber required, which is connected to a non-return valve on the Ink reservoir is connected. At the pump chamber still attached as actuators pistons or bellows-like membranes be on the drive elements, for example the actuating cams are matched to the printer. In the state of the art, this is the case previously required mechanical effort, for example from the U.S. Patent 5,784,087, U.S. Patent 5,825,387, U.S. Patent 5,844,579 and EP 0 870 618 A2 impressively.
- the invention proposes starting from an ink supply tank with the features mentioned in the introduction, that the ink dispenser acts on the ink reservoir Has pressure generating device with the actuators is coupled, and the ink reservoir when actuating the actuators pressurized.
- the peculiarity of the embodiment of the invention is that a innovative operating principle for automatic ink delivery is realized, which of all of the prior art known from Printer actively operated ink supply tanks generally deviates.
- the state of the art has basically been through the ink dispensing device first sucked the ink out of the ink reservoir, compressed in a kind of pump chamber and from there into the ink supply line given.
- the present invention is now the Based on the knowledge that the technically problematic, mechanical Complexity lies in the fact that the ink pump device incorporated between the ink reservoir and the ink supply line is.
- the invention now provides that the Printers still actively driven actuators directly in the Ink reservoir an excess pressure is built up.
- the invention supply line connected directly to the ink reservoir thereby also subjected to excess pressure.
- the according to the invention provided pressure generating device can be pronounced mechanically be simple. In the simplest case, it is sufficient to use the Actuating elements to mechanically compress the ink reservoir, so that its ink content is pressurized into the supply line becomes.
- a preferred embodiment of the invention therefore provides that the Ink reservoir is mechanically compressible and that the pressure generating device has a pressure stamp that with the actuating elements is coupled and when they are actuated Squeezes the ink reservoir.
- the ink reservoir is there constructed entirely or partially from flexible, deformable material. If a force on the actuators by the drive elements of the printer is exercised, the pressure stamp presses on the deformable Ink reservoir, so that in its volume, that is, in the essential incompressible ink, a corresponding overpressure built up which is transferred to the ink supply line.
- the compressible ink reservoir can be designed like a bellows be, for example with molded beads or folds, so that it is in a Direction is compressible.
- it can be designed as a foil bag be, with at least one flexible side wall.
- the container completely as a film bag or bladder, or to attach a more or less rigid, all-round frame, whose frame openings are sealed with deformable ones Foil are closed.
- actuating elements on the Have a pressure-acting, force-intensifying gear.
- a thing Power transmission gear can be designed, for example, as a lever gear his. This contains, for example, single or double levers and is used by the drive element, that is, the drive cam of the Printer, actuating force exerted in a larger pressing force of the pressure stamp implement. It is possible to use the given stroke and the To optimally match the actuating force to the pressure force of the pressure ram, so that the required ink overprint is built up in any case.
- the actuating elements are spring elements have, which compress the ink reservoir spring-biased.
- These spring elements are designed, for example, so that they when inserting the ink supply tank according to the invention into the corresponding recording in the printer against one arranged there Abutment can be pressed.
- they practice a given compressive stress on the ink reservoir from what is already being generated minimum ink overpressure in the ink supply lines.
- the only way to generate the operating pressure is to exercise a Additional power through the actively controlled drive elements of the printer required. This comes from full utilization of the ink volume and especially against sufficient ink pressure at all times.
- the actuating elements can have latching and locking elements, which engage the pressure stamp in the pressed state and counter lock the contact direction.
- the underlying operating principle is known for example from mechanical hoists or presses: At an actuation stroke, the plunger is in a rest position Pressure direction shifted and held there by the locking and pawls. During a subsequent actuation stroke, the pressure stamp is either again moved one notch further in the pressing direction - or - remains in the locked position when the mechanical resistance of the ink reservoir is so big because of the overpressure in it, that currently no more due to the movement of the drive element Pressure increase can be effected.
- the foil bag with respect to the pressure stamp fixed abutment arranged, which corresponds to the pressure stamp is formed.
- the printing stamp for example arched-convex and the abutment shaped accordingly concave is, so that when pressing the plunger against the abutment the in completely displaces ink contained in the foil bag in between, that is, pressed into the ink supply lines. To this In this way, virtually complete recycling of the ink bag is obtained contained ink.
- a practical, particularly simple embodiment of the invention provides that the pressure stamp and the actuating element in one piece as resilient, Double lever rotatably mounted in a housing of the ink supply tank are made of resilient material.
- the double lever can for example can be realized in the form of a spring steel bracket, which at the same time for a power transmission of the actuating force exerted by the drive element serves and ensures the spring preload of the pressure stamp.
- the bracket is curved and corresponds to a corresponding abutment.
- a locking and locking device can also be present.
- the pressure generating device a pressure pump coupled to the actuators has, when actuated the interior of the ink reservoir is pressurized.
- This can be, for example be a simple, small diaphragm air pump that either directly connects the ink tank pressurized with air pressure - or - a displacer or -balloon filled with overpressure.
- An alternative embodiment provides that the ink supply tank over a control valve is connected to a pressure accumulator, which with the Actuators is coupled and is opened when they are actuated.
- a high-pressure gas cartridge for example Contains carbon dioxide, liquefied petroleum gas or the like.
- the printer opens the control valve, which is the highly biased Print medium of this accumulator either directly in the Ink reservoir leads or a displacer or other Pressure transmission device, such as a pressure stamp or the like, applied.
- the ink reservoir and the ink delivery device are expedient arranged in a housing, which is detachably in a corresponding Recording device of the inkjet printer can be used.
- the actuating elements are preferably in a recess or opening attach this housing, in which a linearly displaceable drive element of the inkjet printer can be inserted, for example a drive cam or stamp.
- Get information about how much ink is left in the ink reservoir is a particularly advantageous possibility in that the ink reservoir is compressible and at least a measuring element is arranged on it, which is when pressed together of the ink reservoir moved relative to a second measuring element.
- This technically particularly simple measure is then fundamentally applicable when the ink reservoir as a foil bag or as Bellows is formed, which inevitably deforms when the ink flows away, i.e. contracts.
- According to the present invention simply coupled a measuring element to the movable container wall.
- a second measuring element is fixed in the housing, for example installed so that the distance between the two measuring elements at one Emptying the ink tank and the related one Contraction or pressing changes their distance from each other, the can be recorded as a measured value and is an indication of the filling state of the Ink reservoir indicates.
- a measuring element directly on the ink reservoir for example the wall of a Foil bag attached, or on a pressure stamp against the ink reservoir is pressed and its path of movement also correlates with the ink level.
- a Measuring element firmly attached to the housing of the ink supply tank see above that the distance to the second sensor - depending on the arrangement - in the Emptying the ink reservoir either enlarged or reduced.
- the measuring elements can have switching contacts that for example, close a circuit when the ink reservoir is collapsed or compressed when emptied.
- the use of has inductive or capacitive or optical sensors or the like the advantage that a continuous detection of the ink level with can be carried out with little effort.
- the Numeral 1 denotes an ink supply tank according to the invention. This is only hinted at in the corresponding receiving slot illustrated inkjet printer 2 used.
- the ink supply tank 1 has a housing 3 in which a completely Ink reservoir 4 is arranged.
- This Ink reservoir 4 is as bellows-like, in the direction of the white arrow compressible film bag formed. Its interior is over one Connecting hose with a connection means accessible from the outside, for example, a septum or a connecting valve.
- connection means 6 On this connection means 6 is one for the ink jet print head of the printer 2 leading ink supply line 7 connectable, as shown.
- Reference number 8 denotes a drive element of printer 2, which is drawn in the rest position and by a motor Drive can be moved in the direction of the arrow.
- this drive element 8 Through an opening in the Housing 3 is this drive element 8 against an actuating element in Form of an actuating lever 9 movable about a bearing 10 in the Housing 3 is rotatably mounted.
- this operating lever 9 When actuated by the drive element 8 this operating lever 9 around the bearing 10 counterclockwise twisted, as shown by the arrow below.
- Integrally connected to the actuating lever 9 in the form of a double lever is a pressure stamp 11.
- actuating lever 9 When the actuating lever 9 is actuated by the drive element 8 in the direction of the arrow becomes in the direction of the white one Arrow swiveled.
- the ink reservoir is located on the side opposite the stamp 11 4 on an abutment 12 on the wall of the housing on.
- the ink supply tank 1 shown functions as follows: Receives the printer 2 a print job, is via a motor, not shown Drive moves the drive element 8 in the direction of the arrow and acts thereby on the operating lever 9. The movement of the operating lever 9 leads to a pivoting of the pressure stamp 11 via the bearing 10. This presses the compressible ink reservoir 4 against the abutment 12 together. With that, the inside is Ink is pressurized. Via the connecting hose 5 and that Connection means 6, the ink overpressure plants into the ink supply line 7 continues. This way, each time an incoming print job arrives sufficient operating pressure for the printhead in the ink supply line 7 built.
- the power transmission of the actuating lever 9, the formation of the ink reservoir 4 and the housing 3 are the respective requirements customized.
- the printing stamp 11 and the actuating lever 9 in one piece from resilient material, for example Spring steel sheet, to train, in the inserted state without actuation of the drive element 8 with the ink reservoir 4 Spring pressure applied and thus already a certain minimum ink pressure generated.
- the reference numerals 13a, 13b and 13c electrical or denotes electronic measuring elements which, for example, capacitive, inductive or optical sensors, such as measuring coils, Hall sensors, Capacitor plates, optical transmitting and receiving components or like.
- the measuring element 13a is on the movable wall the ink reservoir 4 or the printing stamp 11 lying thereon appropriate.
- a measuring element 13b or alternatively 13c is fixed in the Housing 3 installed.
- the ink moves in the right wall of the drawing together with the pressure stamp 11 in the direction of the arrow, so that the distance between the measuring elements 13 and 13b decreased or increased between 13a and 13c.
- This change in distance is a direct measure of the level of the Ink reservoir 4 and can have a corresponding, in detail electronic distance measuring device, not shown, between each a pair of sensors 13 can be detected with little effort.
- Ink supply tank 1 can be constructed particularly simply and accordingly requires little manufacturing effort. At the same time is through this structure ensures a particularly high level of operational reliability.
