Definitions
- the invention relates to a method for coating the surfaces of an article of fusible material with colored lines and surfaces by applying a paint layer and then melting the ink layer and / or the surface of the
- the limitation is achieved by selective application of the pasty paint mass, such. B. by a brush or by a printing operation, so the pressing of a color-carrying layer having the dimensions of the desired colored area.
- a pulsating ink jet creates numerous, juxtaposed pixels, which merge into a colored surface.
- An essential limitation of this process is that the working temperature of the dye during application can not be freely selected, but by the Operating principle of the inkjet printer is determined.
- the adhesiveness of the ink layer depends only on how the ink and the surface of the material to be coated react with each other. An influence of the color point is excluded, as soon as the ink has left the nozzle of the inkjet printer.
- a major disadvantage of this method is that the color layer is a solvent such. B. contains water that can react with the object to be coated, him z. B. brings to swelling.
- the invention has the object to develop a method for coating surfaces with lines and delimited areas, for which a very long storable dye is used, which applied in a short time, fixed to the desired surfaces and not from the to be dyed surfaces is removed very quickly.
- the invention presents that the color layer consists of a color powder containing color pigments and a carrier material and is first built dry and then in the field of
- Lines and surfaces is heated and then removed from the remaining areas dry again.
- the decisive feature of the invention is thus the use of powder for building up the color layer.
- This powder does not need to be further processed for its processing.
- Another advantage is that numerous materials such.
- As plastic in the form of a fine powder when applied to a surface electrostatically charge, because they rub against the wall of the container and at the outlet opening or at the nozzle and thereby adhere to the object to be coated. However, this effect is limited to a very small distance from the surface. As a result, the powder layer automatically regulates over the entire surface of the object to be coated away to a uniform layer thickness.
- the application of a powder in contrast to the application of dye mist with solvents, does not require any additional time and no additional heat source to dry off. Rather, the next step of the process can be instantaneous, namely the selective heating of the surfaces and lines to be colored by a directional heat source, such B. a laser beam.
- a directional heat source such B. a laser beam.
- This heat source can act in three variants: If the melting points of the object and the color powder are in a similar range, it makes sense not only to melt the color powder, but also - via the color powder as a heat conductor - to liquefy the surface of the object to be coated , but only up to a very small penetration depth. As a result, the liquid ink layer combines with the melted surface of the article very intimately similar to a welded joint
- the second possibility is that the color powder layer melts, but the surface of the article to be coated does not melt or is only softened. Then, however, the elements of the ink layer are perfectly matched to the surface of the article and penetrate into depressions and openings of the surface structure, whereby they also adhere to it.
- the third possibility is that only the surface of the article melts, but not the particles of color powder, which are then partially enclosed by the liquid components of the surface of the article and thereby adhere.
- the choice of one of these three methods is determined by the material pairing between the color powder and the material of the object.
- the preferred variant is that both the surface and the color powder melt and mix in an area on both sides of the dividing line.
- the color powder used always contains color pigments and a carrier material. In most cases, the color pigments and the carrier material will be different materials. However, it is expressly included in the invention that the carrier material itself can also assume the function of a color pigment. In addition - depending on the application - the color powder may contain other ingredients such. B. a medicinal agent for the production of tablets. It is also conceivable that the color intensity of the pigments is very low or approaches zero.
- the method is suitable for both single-color and multi-colored paint application.
- Multi-color printing is achieved in the simplest case by applying color layers, each with different color pigments, side by side.
- At least one further color layer is applied to and / or directly after a first color layer.
- These two layers of color should then usefully each have the same carrier material or at least one carrier material, which are adjacent to or below the substrate. fuses the carrier material, so that the color layers are intimately interconnected even in the zone of their mutual contact.
- the majority of its particles consist of color pigments which are mechanically firmly bonded to the carrier material.
- the majority of its particles consist of color pigments which are mechanically firmly bonded to the carrier material.
- Color particles with carrier particles consisting primarily of the carrier material to be firmly connected at least on a part of its surface.
- Color powder having an average size of about 40 to 60 microns and the paint particles adhering thereto or at least partially enclosed therein are up to about 15 microns in size.
- Color powder in which color particles are mechanically bound to particles from adhere to the following three steps: In the first step, color pigments and pellets of thermoplastic material in an extruder by melting the plastic are mixed together and formed into a strand. In the second step, they are chopped up to now color pigment-containing pellets, which are then ground in the third step to the color powder.
- thermoplastic material The grinding of a thermoplastic material is hindered by the fact that the frictional heat released during grinding melts the plastic or, in the worst case, even completely liquefies it. To avoid this, in practice, the grinding process is stopped before the plastic particles start to melt. Unfortunately, they are usually still relatively large.
- Too large particles of color powder require a larger amount of energy from the laser. This prolongs the time required and the uniformity and adhesion of the ink layer deteriorates. Therefore, a particle size of the color powder of about 40 to 60 microns is preferred.
- the dry Color powder are transported from a reservoir with compressed air into a nozzle, from where it emerges and meets as color dust on the object to be coated.
- Another alternative to the construction of the color layer is an electrostatic charge of the object to be coated.
- high voltages are required, which must be passed via electrodes to the object to be coated. If this area z. B. is made available for cleaning or waiting for people, the electrodes must be previously discharged.
- the third alternative is a horizontally arranged roll with nubs or other bulges uniformly distributed on the surface.
- a funnel is arranged, which drops color powder on the nubs of the roller. As the roller continues to rotate, the color powder falls by gravity onto the article to be coated. Alternatively, the color powder can also be swept out of the nubs by brushing.
- the fourth variant for distributing the colored powder on the surface of the object to be coated is a sieve.
- This screen can either be "shaken", ie placed in a horizontal, oscillating motion, or instead of moving the screen, a squeegee - a slider that sweeps along the screen - can oscillate, transporting the color powder particles through the screen.
- a piezoelectric crystal or an electromagnet As a drive for the oscillating movements, a piezoelectric crystal or an electromagnet is proposed.
- An alternative drive is an electric motor, either as a rotating motor or as a linear drive. The finer-meshed the wire is, the lower the required amplitude of the strokes, but the faster the lifting movement has to be carried out, ie the frequency of the oscillation must be increased.
- the color layer deposits both in depressions and on elevations of the surface to be coated in about the same layer thickness.
- the application of a paint coat of powder is superior to the application of a solvent-based, viscous paint coat because it flows down from bumps and tends to collect in pits.
- the next step is the selective heating of the lines and surfaces to be coated with paint.
- any directed heat source can be used, such.
- lasers are particularly attractive because they focus a relatively large amount of energy in the smallest space and thereby limit the area to be tempered relatively accurately.
- the inventive principle is not limited to any particular type of laser, but can be performed depending on the material and application with different types of lasers.
- a CO 2 laser is an electrically excited gas laser with typical output power between 10 watts and 20 kilowatts. Its wavelength of 10.6 microns is well above the range of visible light, which is why the light emitted by it mostly with deflecting mirrors of copper or metal-coated silicon on the Color layer is guided. CO 2 lasers are relatively efficient and inexpensive and therefore widely used.
- the excimer lasers generate beams in the ultraviolet wave range.
- Excimer lasers are operated pulsed with a pulse duration usually between 4 and 40 nanoseconds. This type of laser is particularly suitable for very fine and very precisely defined lines and color areas.
- Another widely used variant is a YAG laser, a solid-state laser that contains yttrium and aluminum as a garnet, ie in a special crystal form as a beam-generating medium. But many other types of load types are also usable.
- the rays of the laser or other directed heat sources are always directed exclusively at the lines or surfaces to be colored.
- the power of the heat source must be matched to the material properties of the paint powder and the object. Ideally, both the color powder and the surface of the object to be coated are melted, whereby the penetration depth of the molten zone in the object must comprise only a few molecules.
- increasing the penetration depth makes sense. Convections of the two liquids to be mixed and thus an accelerated and intensified connection result. In most cases, however, the penetration depth is significantly less than 1 millimeter.
- a laser as a heat source can work as a scanning laser or as a scanner laser.
- a raster laser a stencil lets the laser beam radiate only to the lines and surfaces to be heated and covers the remaining areas.
- the advantage is that a powerful ker laser can be used, whereby the time required for heating drops.
- the light beam of a scanning laser is guided along the lines and surfaces to be coated. This eliminates the template, but this increases the time required for heating, so decreases the processing speed.
- the frequency of the laser should be matched to the material properties of the object and the color powder.
- a laser principle can be selected which is suitable.
- Frequency be adapted even better by a frequency multiplier or a frequency divider on the material.
- the lines and surfaces to be coated are fixed by heating, in the third step, the excess color powder must be removed from the outside areas.
- the invention calls for suitable processes: brushing, blowing away or shaking off.
- a practical embodiment is a suction chamber.
- the excess color powder is blown away from the object by compressed air.
- the resulting dust is moved in the chamber by sucking the air contained in it on a filter and deposits on the surface of this filter, only the air occurs between the dust particles and the
- a coating device with three stations makes sense.
- the lines and surfaces to be coated are heated with a directional heat source, such as a laser.
- a directional heat source such as a laser.
- the powder coating is used to apply the color powder layer.
- Powder removal the excess color powder is removed, for. B. in a suction.
- a coating device may consist of three chambers, in which the objects are retracted by opening a gate, processed and driven out through another gate out and in the next station.
- the material of the article and the color powder of course, liquefied by heating, but may not undergo any chemical transformation in this temperature range, which limits the effectiveness and the gastric tolerability.
- a conceivable material could z.
- Another application in the pharmaceutical field is the application of a data matrix code to tablets or tablet boxes.
- This code is used to certify the authenticity of a first, with a specific copy of an inkjet printer on brought matrix codes.
- a reader is used to record the noise behavior of the first Data Matrix code and to store the result of this check in a second printed Data Matrix code.
- such a data matrix code can also be applied to the packaging of a drug. It is particularly interesting, however, to apply this certificate of authenticity on the tablets themselves, which makes subsequent manipulation of an already tested and re-packaged drug very difficult.
- FIGS. 1 a to 1 f represent six successive states during the coating of an article 2.
- the object 2 to be coated is shown in cross-section, wherein the cross-sectional area is designed black.
- the color powder 31 is characterized by a black area with horizontal white lines, the molten color powder by a diagonally finely shaded area and the coating of the lines and areas 1 by a coarse hatched area.
- Figure 1 f is - as before - in cross-section of the object 2 shown as a black area and the adhering thereto line or surface 1 by a rough hatching. It can be seen that this coating stretches beyond the former dividing line between the colored powder 31 and the article 2 into the article 2, that is to say that colored powder 31 and parts of the article 2 have mixed with one another.
- an object to be coated - in this example a hose - located, which passes through as a section of an endless profile from left to right.
- the running direction of the hose is marked by double arrows.
- the next station - in the center of the picture - is the heating of the lines to be coated and areas 1 with a directed heat source 4.
- the third station on the right side of FIG. 2 is the suction chamber 5 for removing the excess color powder 31.
- the powder application 8 a container is contained at the top, which is filled with color powder 31.
- This paint powder 31 is collected through the hopper 81 and fed into a nozzle from which it emerges, which is indicated by another marking of the color powder 31 in FIG.
- the paint powder 31 impinges on the screen 82, with which it is distributed on the tube to be coated.
- the powder application 8 the object 2 has been provided with the ink layer 3, which consists of the coated paint powder 31 so far.
- the heating radiates a directed heat source 4, such.
- a directed heat source 4 such as a laser
- the lines and surfaces of the coating to be fixed.
- the surface fuses with the color powder.
- Figure 2 is shown as an example that the top of the tube 2 is alternately coated and uncoated.
- the areas of the ink layer 3 fixed on the surface are characterized by a rough hatching.
- Color layer 3 still liquid, which is represented by a fine and differently inclined hatching. When they are cooled and thus hardened, this becomes clear in FIG. 2 by the change to a coarse and differently inclined hatching.
- the color powder 31 must not be heated. These areas of the tube run through the second station without melting the color powder 31 of the color layer 3, because the heat source 4 in this
- the powder removal, the unmelted, still powdery residues of the color layer 3 are removed.
- the object 2 runs into the suction chamber 5, in which parts of the ink layer 3 still lying loosely on the object 2 are blown away by compressed air 6.
- the line for the compressed air 6 is shown in Figure 2 by a black line from the air pump 71 to the nozzle in the suction chamber 5. This nozzle is symbolized by an arrowhead.
- the blown-off excess paint powder 31 is sucked in the suction chamber to the filter 51, which is connected to a line in which the negative pressure 7 is generated by the air pump 71.
- the filter 51 passes the air from the suction chamber, but holds the elements of the color powder 31 back. Thereby store these elements to a - not shown in Figure 2 - layer. This layer must be removed at regular intervals.
- the filter 51 via a valve 61 with a line for
- Compressed air 6 connected. At regular intervals, the valve 61 is opened for a short time and thereby leaves compressed air 6 in the filter 51.
- the pressure is so high that it superimposes the negative pressure 7 so that air passes through the meshes of the filter 51 and the elements of the colored powder deposited thereon 31 replaces.
- the elements of the color powder 31 are then driven downward by gravity and are collected in a collecting container 9.
- a similar collection container 9 is also below the first station, the powder application 8, and collects there excess paint powder 31, which has fallen down again during the application.
- FIG. 2 shows that the color powder 31 can be used again from the two collecting containers 9 in the station of the powder application 8. These are either the collection container
