Definitions
- Printing module for an ink printing device with an ink supply container with an integrated ink printing head
- the invention relates to an ink reservoir for an ink printing device with an ink print head which can be arranged thereon, and a method for its production.
- Ink printing devices with ink printing heads which operate according to the piezoelectric or thermoelectric principle, are generally known.
- an ink print head is generally moved along a record carrier with the aid of an electromotive drive device and a print image is generated on the record carrier when the ink print head is excited as a function of the characters.
- the ink printhead is supplied with ink from an ink reservoir, which can either be arranged stationary or can be moved along the recording medium together with the ink printhead.
- the ink print head can form an exchangeable print module together with the ink supply container.
- the ink print head If the ink print head is moved together with the ink reservoir in the form of a print module, the capacity of the ink reservoir is limited due to the required driving forces and the small possible size. Furthermore, care must be taken to ensure that, despite high dynamic loads, an uninterrupted supply of ink to the ink print head is ensured from the ink reservoir.
- the ink supply container must also be constructed in such a way that the ink supply stored therein can be fully used for the writing operation.
- thermoelectric print head An ink reservoir with an integrated thermoelectric print head is known from US Pat. No. 4,771,295.
- Ink supply Containers and ink printhead form a unit in the form of a printing module, which is arranged on a printer carriage of the printing device.
- the entire housing of the ink reservoir is filled with a porous material made of polyurethane foam, which has a controlled porosity.
- At the bottom of the ink supply container there is an ink removal opening in the form of a collar-shaped connecting part which extends into the ink supply container and is closed off from the porous material by a metal mesh grid. This serves to prevent air bubbles and dirt particles from entering the ink supply system.
- the porous material made of polyurethane foam is pressed into the housing under pressure, so that a compression zone results in the immediate vicinity of the connection area.
- the pore size in this compression area is smaller than in a region of the foam which is further away from the connection area. This measure is intended to increase the capillary forces in the vicinity of the connection area so that ink can be reliably supplied to the connection area.
- the tubular connection area protruding into the container space reduces the usable ink supply. There is also the risk that, due to the small size of the connection area in relation to the total supply, the mesh will easily clog with air bubbles and thus block the ink supply. Due to the foam compression, there is still the danger that singular areas with different capillary behavior will arise. Ink islands can thus arise in the foam. A complete emptying of the foam of ink is therefore only possible to a limited extent. Complete drainage also assumes that the foam is completely saturated with ink. Depletion zones have a disadvantageous effect on the ink transport.
- the object of the invention is to provide an ink supply container with an associated ink print head for an ink print device and a method for its production is designed with little effort and enables the most complete emptying possible.
- the penetration of air bubbles into the ink supply system of the ink print head should be prevented without causing an interruption in the ink supply.
- the arrangement of a large-area filter element in connection with the storage element in connection with an ink collecting area located under the filter element enables undisturbed ink removal even if the filter element is partially clogged by air bubbles or dirt.
- the large dirt capacity which can be achieved in this way can make a separate cleaning of the storage element before it is introduced into the ink storage container unnecessary.
- the container volume can be better utilized.
- the storage element consisting of melamine-formaldehyde foam (MF) has no compression areas and therefore no local pore size variation due to targeted compression. This enables easy assembly of the filter element in the ink reservoir with extended tolerances of the reservoir element.
- MF melamine-formaldehyde foam
- the large-area filter element made of plastic fabric that can be wetted with ink in connection with the storage element also acts as a blocking element for air bubbles that have penetrated if the storage element is only slightly impregnated with ink. In order to Large air bubbles can stick to the filter element without disturbing the ink supply. Despite this partial blocking of the filter element, a continuous ink supply is guaranteed.
- the filter element retains its air-blocking effect even if it partially protrudes from the ink level in the foam, because inside the ink reservoir there is a climate saturated with moisture, which prevents the filter from drying.
- the ink collecting area arranged under the filter element with spacing means to ensure a predetermined distance between the filter element and a bottom surface of the ink collecting area also enables an ink flow when the supply element presses against the screen. It is not possible to pinch off the ink supply opening.
- the entire ink supply container can be produced very easily in the plastic injection molding process, without having to pay attention to exact tolerances.
- the cover closing the ink supply container also serves as protection for the ink print head or as a sealing surface for a sealing cap arranged in the printer.
- the arrangement of the ink printhead and a contact plate on a mounting surface on the outside of the ink reservoir enables simple and reliable contacting of the printing module in a holding device of a printer carriage of the printing device.
- Guide and positioning elements arranged in the holding device ensure reliable, clear and wear-free positioning, even when the pressure module is changed frequently.

- FIG. 8 shows a schematic illustration of the contact area between the pressure module and holder, partly in a sectional view
- Figure 9 is a side view of the printing module.
- Figure 10 is a sectional view of the positioning elements of the printing module.
- An ink printing device shown in FIGS. 1 and 2 contains a printer carriage 10 in the form of a holder for exchangeably accommodating a printing module 11.
- the printer carriage 10 is guided on guide rods 12 and is, for example, about an electromotive drive device 13 moves over ropes 14 in printing operation on these guide rods 12, of which only one is shown here, back and forth.
- the print module itself consists of a housing 15 made of plastic injection molding with a mounting surface 16 for an ink print head 17, which is designed as a so-called bubble jet ink print head - a print head that works with heating elements as drive elements.
- it is also possible to use other types of ink print heads for example ink print heads with piezoelectric drive elements.
- the ink print head 17 used in the exemplary embodiment and working according to the thermoelectric principle is constructed in layers in accordance with the illustration in FIG. 3 and has nozzle channels 18 with heating elements 19 arranged therein.
- An ink chamber 21 with an approximately circular ink supply opening 22 is located upstream of the nozzle channels in the transport direction of the ink 20.
- the ink supply opening 22 leads through a silicon substrate layer carrying the nozzle channels 18 with a base layer 24 made of aluminum arranged underneath. However, this base layer 24 can also be dispensed with or it can consist of a different material.
- the ink chamber 21 and the nozzle channels 18 are covered by a cover layer 25 in the form of a cover plate.
- the ink print head 17 is fastened on the mounting surface 16 of the housing 15 in such a way (FIG. 1) that the nozzle channels 18 run parallel to the mounting surface 16.
- a vapor bubble is formed in a known manner above the heating elements 19, which ensures that the ink 20 is expelled in droplets via nozzle outlet openings 26 of the nozzle channels 18.
- a contact plate 27, e.g. attached by gluing which has corresponding raised contact nipples 28 corresponding to the number of heating elements to be controlled - in this case 50 heating elements
- connection area 30 of the contact plate and the connection area 31 of the ink print head is made, for example, by bonding or other known connection techniques or, for example, by a plug contact.
- the printing module 11 basically consists of an ink reservoir 32 with an ink print head 17 arranged thereon.
- the ink reservoir itself, in accordance with the illustration in FIG. 4, consists of the housing 15 with the mounting surface 16 for the Ink print head, the mounting surface 16 having an ink supply opening 33 which interacts with the ink supply opening 22 of the ink print head 17, as can be seen from the detailed illustration of the bottom region of the ink supply container in FIGS. 5 and 6.
- An ink collecting area 34 is formed in the housing 15 of the ink reservoir 32 adjacent to the mounting surface 16 inwards.
- the housing 15 In principle, it consists of a recess at the bottom of the housing 15 with a large number of spacer elements 35 in the form of ribs or small columns and the recessed ink supply opening 33.
- the ink collecting area 34 with its spacer elements 35 is covered over a large area through a filter element 36 in the form of a plastic network made of polyamide with ink passing channels (pores) with a diameter of 3 - 35 ⁇ m and a filter thickness of about 0.1 mm.
- a plastic mesh it is also possible to use a metal mesh or another structure which has ink passage channels of the corresponding pore size. Decisive for the selection of the material, however, is its wettability with the ink 20 used.
- a reservoir element 38 made of a microchannel-structured, ink-absorbing and dispensing material, for example melamine-formaldehyde Foam (MF).
- MF melamine-formaldehyde foam
- the storage element can also be produced from other, for example fibrous, material.
- melamine-formaldehyde foam has proven to be a particularly advantageous material. This is a skeletal structure made of three-dimensionally branched fibers. In contrast to the usual foam with partially broken chamber walls, such a skeletal fiber foam has a much higher usable volume.
- the thin, branched fibers form interconnected cavity structures, the fibers having a relatively large length / diameter ratio of approximately 10: 1 or more.
- the pore size ie the size of the cavity structures, is approximately 50 ⁇ m to 175 ⁇ m, the majority of the pores having a size of approximately 140 ⁇ m to 160 ⁇ m.
- the pore size of the smallest pores hardly falls below 75 ⁇ m, a relatively constant pore size results, so that the foam can be completely emptied of ink or filled with ink.
- the composition of the foam material As far as the composition of the foam material is concerned, it must be such that it can be wetted by the ink used, but does not swell or absorb components of the ink under the influence of the ink.
- a material that contains more than 80% melamine-formaldehyde condensate has proven to be a cheap material.
- Particularly advantageous is an unmodified temperature-adjusted melamine-formaldehyde condensate with three-dimensionally branched fibers that form a type of tissue, the fibers being connected to one another, with a length to width to diameter ratio of approximately 10: 1 or greater and with a fiber density on the order of 1.1 grams per milliliter or greater. Tissue structures that are too short, i.e. in which the length-to-diameter ratio is too low, the usable storage volume can be reduced.
- Melamine foam for use in ink containers can be melamine-formaldehyde condensates which, in addition to melamine, also contain up to 50%, preferably 20%, of other materials from the field of temperature-controlled resins and which, in addition to formaldehyde, also have other aldehydes.
- the supply element 38 lies flat on the filter element 36 without any particular pressure and is in contact with it.
- the ink 20 stored in the supply element 38 penetrates through the filter element 36 through this contact contact and fills the ink collection area 34 underneath. From there it is continued via the ink supply opening 33 to the ink supply opening 22 of the ink print head 17.
- the filter element 36 has the task of retaining air bubbles 39 located in the ink supply container 37 (FIG. 6) by capillary action of the ink passage channels 37, so that air bubbles 39 cannot penetrate into the ink supply system of the ink print head. This could cause the ink printhead to fail.
- the pore size of the ink passage channels 37 is designed such that at the highest pressure difference that occurs between the ink reservoir 32 and the ink print head 17, e.g. due to different levels or due to the influence of a vacuum pump used to flush the print head, no air can penetrate through the filter element 36.
- the large-scale design of the ink collecting area 34 in connection with the filter element 36 and the storage element 38 ensures an ink supply even if, as shown in FIG. 6, parts of the filter element 36 are blocked by a larger air bubble 39 are.
- the filter element 36 still retains its air blocking effect even if it partially protrudes from the ink 20, e.g. shown in Figure 4, because inside the ink container 32, there is a climate saturated with moisture.
- the filter element can also retain dirt particles.
- the ink reservoir 32 is covered with a housing cover 41, which printhead 17 surrounding area 42, which represents a protection against contact for the ink printhead 17. It also acts as a spacer for the ink print head 17, in order to prevent the outlet openings 26 of the ink print head from coming into contact with the recording medium of the ink print device and thus becoming soiled, and it serves as a sealing surface for a sealing cap arranged in the printer the outlet openings are closed for longer breaks.
- the printing module 11 is fastened in an interchangeable manner in the holder of the printing carriage 10.
- counter contact elements 44 are arranged on a film 43 on the side surface of the holder 10, as shown in FIG.
- These mating contact elements 44 consist of raised gold-plated contact nipples which are attached to the film 43, an elastic consisting of elastomer between the film 43 and the side surface of the holder 10
- Layer 45 is arranged, which ensures good contact due to its elasticity.
- the mating contact elements 44 with the foil 43 are connected to a foil line 46.
- guide elements 47 are provided in the side surface of the holder 10 and on the printing module for a correct positioning of the printing module 11 in the holder.
- the printing module 11 according to FIG. 9 has three openings 48, 49, 50 on its mounting surface, into which the three spherical, for example guide elements 47 engage in the holder 10 when the printing module 11 is inserted (FIG 10).
- the guide elements can also be arranged rigidly without springs.
- the upper opening 48 on the mounting surface 16 consists of a flat, somewhat recessed surface.
- a further centering opening 49 arranged below this opening 48 consists of a conical slot, and one on the right edge of the mounting surface. Before 16 approximately centering 50 has the shape of a cone.
- the pressure module 11 is tied and centered in the holder 10 with regard to all degrees of freedom.
- a pressing force is exerted on a side surface of the pressure module 11 via a clamping lever 51 (FIG. 2).
- the pressure module is thus centered via the centering openings 48, 49, 50 and the contact nipples 28 and the mating contact elements 44 come into contact with one another in the correct position.
- the centering elements 47 also prevent the pressure module from being inserted incorrectly.
- the printing module 11 is manufactured as follows:
- the housing 15 with the mounting surface 16 and the ink collecting area 34 is produced in the plastic injection molding process.
- the plastic filter element 36 is then introduced into the ink reservoir 32 and welded to the housing 15 at the edges.
- the separately manufactured storage element 38 made of melamine-formaldehyde foam is then inserted into the housing 15, to the extent that the storage element 38 comes into contact with the filter element 36.
- the housing 15 is covered with the cover 42.
- the storage element e.g. filled with ink using a hollow needle.
- Deviating from this production process it is e.g. it is also possible to mount the ink print head 17 and the contact plate 27 on the mounting surface of the housing 15 immediately after the housing 15 has been produced, and then to introduce the storage element 38 into the housing.
- the supply element 38 by foaming in the housing 15 itself. After filling the ink reservoir 32 with ink, it is necessary to remove air located in the ink collecting area and in the ink chamber 21 of the ink print head. For this purpose, the air is sucked out, for example, via a vacuum bell over the nozzle openings of the nozzle channels 18, so that the ink collecting area and the nozzle channels including the nozzle chambers are completely filled with ink. Once a closed communicating liquid system has been built up, the ink supply container or the ink supply element 38 empties from above in the direction of the ink supply opening 33. This emptying is independent of the position of the ink print head. In the embodiment shown in FIG.
- the ink print head is arranged in the upper region of the housing 15. This ensures that no ink leaks from the nozzle outlet openings 26 during the breaks in operation of the ink print head. As a result of the capillary action at the nozzle outlet openings 26 between ink and air, no air can penetrate into the nozzle channels via the nozzle outlet openings 26. Conversely, when the heating elements 19 are actuated, the activity of the heating elements ensures that ink is conveyed out of the supply element independently of the position of the ink supply opening 33. It is only important that the ink supply opening 33 is completely filled with ink. This is ensured by the ink collecting area 34.
