Definitions

  • the invention relates to the very broad sector of printing in general on very various supports, and the adopting of especially ceramictile decoration and glazing to this broader sector.
  • the ceramic tile decoration and glazing process specifically referred-to is the one described in European patent no. 0 677 364 , which related to a rotary machine for decorating and glazing, in particular for ceramic tiles, which machine comprises:
  • the machine and process of the present invention enable high production rhythms, do not require the constant presence of operators for controlling the results of the decoration and printing, and at the same time exhibit a very long working life for the matrices, with only very small maintenance needs.
  • the invention also enables decoration to be made on soft or flexible materials, as well as rigid materials having very regular shapes, without causing breakages, and while maintaining very high product quality of transfer of a decoration and printing.
  • 1 schematically denotes an infeed device for tiles 2, whereon the tiles are conveyed in the sense and direction indicated by arrow 15.
  • the infeed device 1 can be a traditional conveyor belt supported inferiorly by a plane along which the upper branch of the belt slides.
  • the infeed device 1 is inserted into a usual panel transport line.
  • the panels can be slabs and/or sheets, such as for example panes of glass for building and industrial uses, or plasterboard panels, or panels, slabs or sheets made of plastic materials, or concrete fibres, and so on.
  • a rotary decoration and glazing apparatus is positioned above the infeed device 1 and comprises a matrix cylinder 3 rotating about its own axis in the direction indicated by arrow 18, which matrix cylinder 3 comprises a centre 34 externally bearing an elastically deformable peripheral layer which in turn is externally and peripherally covered by a smooth cylindrical cylindrical external surface 30.
  • the elastically deformable part comprises a soft and spongy inner layer 32 and an external layer 33, also elastically deformable but more compact than the inner layer 32.
  • the inner layer 32 is made of silicone foam, while the external layer 33 is made in silicone rubber, which in a preferred embodiment is polymerized by polyaddition.
  • the centre 34 exhibits two crowns 35 and 36, having the same external diameter as the cylindrical external surface 30, to which they are coaxial.
  • the whole matrix cylinder 3 is supported by a shaft which is not illustrated in the figures.
  • External constant-section annular channels 37 are provided on both crowns 35 and 36 and extend over all of the periphery thereof.
  • liquid collecting baths 5 and 6 are situated below the downfacing side of the annular channels 37 of each of the crowns 35 and 36, which are inferiorly provided with liquid collection pipes 7 leading to a container 8 positioned below the apparatus and functioning also as a reservoir for the liquid or paste, which is removed from the container by means of a feed pipe 9.
  • the matrix set on the smooth cylindrical external surface 30 of the matrix cylinder 3, comprises a plurality of microscopic cavities 31 all of which retain a small amount of liquid.
  • the cavities 31 are uniformly distributed over all of the cylindrical external surface 30, and are characterised in that they exhibit a more or less constant breadth-depth ratio.
  • a doctor 4 Arranged in contact with the cylindrical surface 30 and along a generatrix of the matrix cylinder 3 is a doctor 4 supported on a frame 12 by means of a pivot 13.
  • a screw device 14 acting between the doctor 4 and the frame 12 permits an adjusting of the pressure with which the blade of the doctor 4 presses against the cylindrical external surface 30 of the matrix cylinder 3.
  • the doctor 4 as is clearly illustrated in figure 2, not only contacts the silicone cylindrical external surface 30 but also the coaxial external cylindrical surfaces of the crowns 35 and 36.
  • the doctor 4 oscillates alternatingly in a parallel direction to the matrix cylinder 3 axis, a movement which is transmitted to the frame 12 by a known-type device (not illustrated).
  • the frame 12 is supported on a support arm 21 which is rotatable about a parallel axis to the matrix cylinder 3 axis.
  • the doctor 4 can be arranged at various inclinations with respect to the cylindrical external surface 30 of the matrix cylinder 3, so that the best configuration can be found for filling the cavities 31 and for cleaning the cylindrical external surface 30.
  • the doctor 4 has a further very important function of refreshing, in effect, the liquid, by mixing it continuously, and also partially renews the liquid (or paste) inside the cavities 31, especially when, during the course of a rotation, not all of the liquid already lodged in the cavities 31 is laid on the panels.
  • a still further function of the doctor 4 is to free the cylindrical external surface 30 from any impurities or extraneous bodies, by shifting such detritus to the edges thereof.
  • a second doctor 25 is provided upstream of the first doctor 4 and has the function of effecting a first scraping and cleaning of the cylindrical external surface 30 so as to facilitate the subsequent reloading the cavities 31.
  • the liquid o paste for decorating or printing is brought into the space comprised between the doctor 4 and the adjacent portion of the cylindrical external surface 30 through the feed pipe 9, which has its exit mouth situated in the appropriate zone.
  • the liquid is collected from the same container 8 into which the excess liquid is sent from the annular channels 37.
  • the above-mentioned extraneous matter is also sent down with the liquid from the annular channels 37, and is deposited therewith in the baths 5 and 6, wherefrom the liquid flows down through the collection pipes 7 and into the container 8, located below the infeed device 1 and removable, being mounted on wheels 10 and resting on the floor.
  • the matrix cylinder 3 is set in rotation by a motor head 20 positioned by the side of the infeed device 1.
  • the motor head 20 can move vertically to enable height-regulation of the matrix cylinder 3 with respect to the infeed device 1 conveying the panels 2.
  • the motorization (not illustrated) producing the rotation of the matrix cylinder 3 is connected with the motorization producing the advancement of the panels 2 on the infeed device 1 such that the cylindrical external surface rotates without dragging and exerts a preestablished pressure on the upper surface of the panels 2 transiting on the infeed device 1.
  • the doctor 4 scrapes the cylindrical external surface 30, distributing the liquid and "freshening it” by continually remixing it, at least partially, inside the cavities 31.
  • the liquid contained in the cavities 31 is at least partially extracted and deposited on said panel surface and reproduces, in plan, the distributions of the cavities 31 distributed on the cylindrical external surface 30 constituting the matrix.
  • the depositing of the liquid for decorating or printing on the surface of the panels will be a true reproduction of the arrangement of the cells on the matrix situated on the external cylindrical surface 30; the small quantities of liquid transferred onto the surfaces of the panels will exactly correspond to the quantities of liquid contained in the cavities 31: the larger-size cells will deposit larger quantities of liquid, and the smaller-sizes cells will according deposit smaller quantities of liquid. This permits an excellent range of half-tones.
  • the infeed device supports and transfers material to be printed or decorated in the form of continuous sheets, and is constituted by usual means, not illustrated in the figures of the drawings, which means keep the materials to be printed tensed, so that the advance in a perpendicular direction to the axis of the matrix cylinder 3 in synchrony with the rotation direction of the cylinder, so that rolling with no drag is obtained of the smooth external cylinder surface (30), with a predetermined pressure on the surfaces of the materials to be printed or decorated.
  • any type of sheets can be decorated or printed on, for example metal materials unwinding directly from reels.
  • the decorating machine thus, realizes a decoration and glazing process, in particular for ceramic panels, which is characterized in that it comprises:
  • An advantage of the present invention is that the device is self-cleaning: before coming into contact with the panel, the doctor 4 scrapes the cylinder 3 and thus at the same time cleans the cylindrical external surface 30 and fills the cavities 31.
  • a further advantage is the operative speed of the device.
