- FIG. 1 shows a printing device in front view.
- FIG. 2 represents the device in rear view.
- FIG. S represents the device in exploded front view.
- FIG. 4 shows the device in exploded rear view.
- Figure 1 illustrates an airbrush printing device 1 according to the invention.
- the printing device 1 allows the printing by airbrush of a representation for example on a sheet of paper to be printed 10.
- the paper must be of high quality for a better result.
- control panel 23 in which the representation is stored digitally, for example in an internal memory or via a remote server, so that the control panel 23 can provide this representation to the rest of the machine which will use it to carry out the impression.
- the controls of the control panel 23 allow the user to select the chosen task on the company's website, which can thus either sell the device 1, or sell the service of its use from a downloaded representation.
- the service provided creates the ready-to-use mixed ink cylinders. Colors cannot be mixed directly and must be applied in separate layers. The images with shades of a color, in particular of gray, are created in monochrome, therefore produced from the same mixture.
- the device 1 comprises a plate 9 of flat shape. It is suitable for the reception of the sheet of paper which is arranged on top of it.
- the plate 9 indeed provides the device 1 with an essential flat surface on which to paint.
- the device can provide for example that the tray is adapted to receive printing paper in the standard format of two hundred and ninety-seven millimeters by four hundred and twenty millimeters.
- the device 1 also includes an airbrush 7 which is suitable for airbrush printing, from the representation provided by the control panel.
- the Airbrush Trigger 7 can use a stepper motor to activate an air hose on it and spray this air along with the mixture onto the paper.
- Airbrush 7 uses paint and compressed air to create printed images on the sheet from the representation.
- the airbrush 7 has, unlike known printers, a hopper, and a reservoir 21 adapted to receive ashes and ink to be mixed by the hopper.
- the ashes make it possible to create beautiful, tailor-made images thanks to the device.
- the Ash Airbrush 7 gives the final image a distinct soft, slightly hazy effect unique to each image.
- the incorporation of ashes gives a poetic note to the work obtained, these ashes being able to be linked to the representation itself. For example, we can represent a plant by incorporating ashes from the cremation of this same plant, or a landscape or a still life by incorporating several ashes obtained from the cremations of the elements represented.
- the airbrush 7 is adapted to be able to produce airbrush prints from the mixture contained in said reservoir and supplied by the hopper.
- the reservoir has for example the shape of a cylinder.
- This cylinder is reusable. It can also be removably mounted on the airbrush 7, so that when the special ink mixture is poured into the hopper of the cylinder, this cylinder can be at least partially used on at least a portion of the front sheet to be swapped with another cylinder providing another mixture, in particular if the images require several layers in different colors because the device 1 cannot mix the colors automatically.
- the airbrush 7 is also mounted to move relative to the plate 9 along three orthogonal axes, namely two horizontal axes (antero/posterior and left/right) a vertical ascending axis.
- the airbrush 7 is thus capable of moving relative to the sheet, from right to left and from front to back to project the mixture of ink and ash onto the latter, and from top to bottom to position itself at the correct distance from it.
- the airbrush 7 is digitally controlled in its positions along said three axes by the control panel 23 to allow the printing by airbrush of the digital representation on the sheet of paper to be printed 10.
- the hopper is a metering hopper adapted to be able to adjust the ash and ink concentration in the tank.
- a dosing hopper allows adjustment of the concentration of the mixture according to preconfigured parameters.
- the airbrush 7 is configured to be able to be moved horizontally and vertically according to lead screws 15 and from position servo commands issued by the control panel 23.
- the lead screws 15 are made of metal, for example lead, aluminum or steel.
- the lead screw 15 which is along the vertical axis may comprise a housing 12 dedicated to this axis, as well as to the support of the airbrush 7, of the hopper, of the reservoir, which move vertically simultaneously with respect to the sheet.
- linear translation guide elements 13 are coupled to at least one of the lead screws 15.
- These guide elements 13 are sliding linear rails or bars, parallel to the lead screws.
- Brackets 29 attach the slide rails to each motor and couplers 31 couple the outputs of each motor 11 to the lead screw 15 by tightening the lead screw 15 to the motor shaft 11.
- mother 15, two linear bearings 33 drive, i.e. move up and down or move forward and back, the rail 13.
- a bearing 37 allows the lead screw 15 to rotate smoothly, for example a plain bearing or a ball bearing.
- three orthogonal lead screws each extending respectively along one of the three orthogonal axes and each of said lead screws is coupled to one of the three drive motors 11 of the airbrush and is suitable for rotational drive of said lead screws.
- the motors 11 are controlled by a control circuit module 41, having an electronic card 43, included in a protection box 25 and coupled to the control panel 23.
- the module 41 can for example receive its instructions movement from the control panel 23 or from the electronic card 43, the latter interpreting the given representation by the control panel 23 in instructions to move the airbrush 7 relative to the sheet.
- the lead screws can be held in their respective axial positions by structural supports with aluminum frames 3,39,45.
- the frames 3,39,45 comprise for example a substantially horizontal frame 3.
- This horizontal frame 3 serves as the basis for the device 1.
- a front-rear frame 39 having two sides 5 joined by a left-right frame 6 which structure the assembly.
- the set of frames 3,39,45 is fixed by fixing means 44 which are all standard.
- the device 1 can thus be completely disassembled.
- the device 1 can further comprise a support 49 for the tray 9, comprising five aluminum sections bolted to the horizontal frame 3.
- the support 49 is mounted on the horizontal frame 3 itself mounted on feet 53, which can be used to help to level the plate 9 with respect to the horizontal. They also confer adhesion to the surface on which the device 1 is placed. They are for example made of rubber. They may include a thread to be adjusted in height by screwing into the support 49 and/or into the horizontal frame 3.
- each lead screw makes it possible to move the hopper for airbrush printing along its axis which is orthogonal to the axes of the other lead screws.
- Each frame 3,39,45 provides support for a lead screw 15 and its motor 11. We therefore want to avoid any contact with the sheet during the transverse movements of each motor 11 and its lead screw 15, which is made possible by the cable tray 42 which keeps all the wires in place while the device is moving.
- a metering hopper located downstream of the tank makes it possible to automatically adjust the ash and ink concentrations, depending on the desired effect, for example.
- upstream and downstream are defined with respect to the direction of circulation of the ink and the ash in the airbrush. When two elements are connected, it means that the ink or the ashes can circulate between these two elements.
- Ash can be mixed with ink through the hopper to adjust the ash concentration.
- the metering hopper may include a funnel-shaped container (conical, wedge-shaped, pyramidal, etc.), a first ink reservoir and a second ash reservoir, upstream of the funnel-shaped container. These two tanks can be used to store ashes and ink for graphic printing. These two reservoirs can each be connected to the hopper, more particularly to the funnel-shaped container, in order to supply it with the ink and the ashes separately.
- the container of the hopper can also contain a membrane arranged for example vertically in order to separate the two compounds.
- the walls of the hopper as well as the membrane define two chambers, each chamber comprising one of the two compounds, that is to say the ink and the ashes.
- Each compound can then be evacuated into the reservoir 21 by metering means connected to each chamber.
- Each dosing means located in the lower part of the funnel-shaped container, discharges the desired quantity of each compound to the reservoir 21 or to a mixer, located downstream of the funnel-shaped container, to finally be discharged into the tank 21.
- the metering hopper and more particularly the metering means can also be connected to a control system making it possible to control the concentrations of ink and ash supplied to the reservoir before spraying on the support.
- the ashes in the ash container can be in the form of powder.
- the dosing means for the ashes can then comprise a powder dosing system.
- the ashes are retained in the chamber of the hopper and are delivered to the tank 21 or to the mixer, upstream of the tank 21, per unit of time, for example by an endless screw (such as an Archimedean screw) whose speed of rotation is adjustable.
- the dosing means can also be provided by volumetric or gravimetric dosers.
- the volumetric screw feeders are equipped with a swirler which is used both to measure the volume and to evacuate the product at each turn.
- the advantage of this type of dispenser is that the volume is identical at each cycle (for example, at each rotation of the auger) and that the product density is regular.
- Single-screw, twin-screw and triple-screw feeders can be used.
- the ashes are stored in a chamber in the hopper connected to a dynamic scale which constantly measures their weight, which allows very precise dosing.
- the ash can also be pre-ground to achieve a finer powder and a finer airbrushed image with less grit.
- the ashes can be ground by molding means such as at least one of a mortar and pestle, by ultrasound, by a grinder or by a ball mill.
- the second tank comprising the ashes can also be equipped with a grinder.
- One or more dispersants may be added during molding to stabilize the dispersion of ash in the liquid for graphic printing.
- the molding means can be integrated in the container comprising the ashes or in the chamber comprising the ashes.
- the ashes provided in the ash container can be mixed beforehand with a solvent or water and optionally a binder to provide the ashes in the form of a liquid, pasty or gelatinous medium.
- Dosing means can be supplied by volumetric and gravimetric, piston, membrane, valve and peristaltic feeders to the mixer.
- the use of a binder makes it possible to fix the ash particles on the printed image.
- the binder can be mixed with the ash-supplying medium and/or be present in one or more inks.
- the printing can be carried out by one or more inks, for example with different colors.
- a device can be used to adjust the mixture of two or more inks.
- inks and paints can be used, such as solvent-based, oil-based, water-based, ultraviolet-curing inks, acrylic paints, watercolors, Indian inks, etc.
- the colors can be obtained by dyes and/or organic and/or inorganic pigments.
- Different graphic effects can be obtained by using special effect inks, such as fluorescent inks, metallic inks, etc.
- the metering means for the ink include, for example, volumetric and gravimetric, piston, membrane, valve and peristaltic metering devices.
