Definitions

  • the invention relates to a method and an apparatus for Applying and / or introducing a color decoration onto or into an object, in which a carrier with dye in contact with the object is brought to dye from the carrier to the object transferred to.
  • the invention is based on a prior art as it is based EP-A 0 282 859 "Method and device for applying a Decorations on an object "is known.
  • a color decor from sublimable dyes first applied to a carrier.
  • the carrier can e.g. B. are made of paper. This color decor should then on from the carrier the object to be decorated is transferred.
  • the object can e.g. B. consist of a suitable plastic or also from another material, e.g. B. with plastic or Lacquer is coated.
  • the carrier is placed over the object and by increasing the temperature the color decor is transferred from the carrier to the sublimation Transfer the item.
  • a cloth made of elastic in the cited prior art Material e.g. silicone
  • a vacuum pump is placed over the table on which the object a vacuum is deposited with the carrier and the drape generated, which sucks the carrier with the overlying cloth.
  • the present invention finds z. B. at this level Technology - with or without silicone cloth - application.
  • the invention is based on a prior art, as described in EP-A 0 573 676 "using a carrier "release” properties for applying varnish and paint on a substrate ".
  • carriers e.g. from suitable paper
  • release so-called “release” properties used to transfer a decor to an object.
  • the "release” property of the wearer means that the Peel off the decor in the manner of a "decal” and can be transferred to the object in this way.
  • the invention is based on the object, the method and Devices according to the aforementioned prior art especially with regard to the quality of the color decoration improve.
  • the method according to the invention is characterized in claim 1.
  • This technique is special both in the sublimation transfer mentioned at the beginning as well Can be used for "release" transfer of the color decor.
  • the Gas jet causes the wearer to lie tightly over the entire surface on the object without gas inclusions or other inhomogeneities.
  • the gas jet can over the object with it Carrier (and possibly the elastic Cloth) in the manner of a "doctor knife". In doing so, gas inclusions are struck out and a rich one All-over contact of the wearer with the object is guaranteed.
  • the gas jet in at least one Direction has a dimension that is small compared to the dimension of the object in this direction. It is special preferably provided that the gas jet in the form of a Knife has and linearly over the carrier or that, if necessary cloth lying on it is guided.
  • the line has Gas jet prefers a length that is greater than the width of the object plus the overlapping areas the carrier or the cloth.
  • the knife-shaped described above Design of the gas jet provided that the direction of the line at least one gas jet an angle with the direction the relative movement between the gas jet and the object, which is different from 0 ° and 90 °.
  • Another preferred embodiment of the invention in particular when using sublimable dyes Color decor is used, provides that the gas jet on a temperature is heated at which it causes or at least promotes that the dye sublimes and so from the carrier to the Object passes.
  • the invention enables in particular a high quality of colored decoration of the object in the edge area, if the gas jet is directed obliquely towards the edge area being the carrier on both sides of the edge presses evenly.
  • the gas jet according to the invention can be with or without the one described above Suction effect used with the use of a vacuum pump become.
  • Figure 1 shows an object to be decorated 10.
  • the embodiment 10 is intended to be subject to sublimable Disperse dyes are decorated.
  • the object 10 can e.g. B. consist of plastic into which the dye molecules can diffuse into it.
  • the Carrier 12 consists in the illustrated embodiment Paper. With the printed side down, the carrier 12 1 over the object 10, so that the paper protrudes over the edges. About the carrier 12 is an elastic Cloth 14, e.g. B. made of silicone. The object 10 with the carrier 12 and the cloth 14 is on a table 16. Im Table 16 has a channel 18 formed with branches 18a. The Arrow 22 indicates a connection to a suction pump (not shown) directly via the channels 18 and the branches 18a creates a vacuum above the table top, so that the cloth 14 is sucked with the underlying carrier 12 and dragged over item 10. As such, this is in the described above prior art.
  • a gas jet 20 acts on the cloth 14 and so presses the Carrier 12 against the object 10.
  • the gas jet 20 has a line shape with a line width, which is very small compared to the dimension of the Item 10.
  • the elongated narrow gas jet 20 can z. B. have a width of a few millimeters, for. Legs Minimum width of about 1 mm and a maximum width of 10 mm Or less.
  • the gas jet 20 is guided over the object 10 so that it successively in Figures 1 and 2 z. B. from left to right via the carrier 14 and the underlying object 10 sweeps.
  • the gas jet is guided in particular in such a way that he in the critical edge area of the object for a clean Transfer of the color decor ensures. This is shown below of Figure 5 explained in more detail.
  • FIGS 3 and 4 schematically show an embodiment of a gas jet generator 24.
  • the gas jet generator has one Port 28 in the hot air through an inlet 16 in Flows in the direction of the arrows. There is a blower in front of the nozzle (not shown) arranged. A heater for the gas is indicated schematically by the reference numeral 32.
  • the hot one Gas flow passes through the nozzle 28 into a funnel 30 which 4 to a nozzle 34 with the diameter "D" rejuvenated. This structure of the funnel 30 creates a linear one Gas jet 20 according to Figure 2.
  • the gas flow through the Funnel 30 is such that by a suitable structure of the Funnel 30 and / or special chokes in the funnel through the hot gas stream exiting the nozzle 34 over the entire length of the linear gas jet 20 (cf. FIG. 2) at least approximately is homogeneous, d. H. the gas jet has in every unit area at least approximately the same intensity and speed, so that the pressure distribution generated by the gas jet between Carrier and object over the entire extension of the Gas jet is essentially homogeneous.
  • the gas jet 20 is heated to a temperature at which it heats the carrier 12 and the color decor printed thereon to the extent that the desired sublimation of the dye molecules expires for transfer to item 10. This will a very homogeneous heating in the area of action of the gas jet achieved and sublimation can be very effective in a short time be performed. In comparison with state of the art IR emitters technology, the energy consumption is considerably reduced.
  • the gas jet can be set in a number of parameters easy to control, e.g. B. with respect to the generated on the carrier Pressure and / or temperature of the gas. This can be an optimal Adaptation to the conditions of the object to be printed and the carrier.
  • FIG 5 shows schematically a modification of the above Embodiment with two gas jets 20a and 20b.
  • the table 16 is designed here as a carriage, which itself 5 moved in the direction of arrow 36.
  • the two line-shaped Gas jets 20a, 20b are stationary.
  • the edges of the Object 10 are in Figure 5 with the reference numerals 38, 40, 42, 44 designated.
  • the two linear gas jets 20a, 20b form with the feed direction 36, ie the direction of the Relative movement between table 16 and gas jets, angle ⁇ or ⁇ . These angles are different from 0 ° and 90 °.
  • the first Gas jet 20a obliquely detects the leading edge 42 and the Side edge 38 of the article 10, so that the carrier also in Edge area is pressed evenly.
  • the slant has a particularly high quality color transfer in the edge area result.
  • the likewise inclined second gas jet 20b is detected the leading edge 42 and the other side edge 40 of the Item 10.
  • Gas jets 20a and 20b can be the knife-shaped gas jets also be placed at an angle to the drawing level, d. H. the angle between the "knife blade" of the gas jet and the surface the carrier 12 or cloth 14 is not necessarily the same 90 °.
  • An inclination of the gas jet in relation to the main level of the carrier 12 has the result that the hot gases against the direction of the relative movement 36 flow and so the carrier 12 before entering the area of action of the gas jet is preheated. It is understood that air is suitable as a gas is.
  • the inclination of the gas jets enables in particular even heating in the edge area.
  • the method and the device described above can z. B. modified so that when in use a carrier with "release" properties worked without silicone cloth becomes.
  • the gas can also be heated be dispensed with in many cases.
