Definitions

  • the present invention relates to a digital printer for the decoration of slabshaped manufactured articles.
  • lab-shaped manufactured articles means any product of flattened conformation having two dimensions of spatial extension (i.e. width and length) significantly larger than the third dimension (i.e. thickness), regardless of the material (rigid, soft or flexible) composing it.
  • tiles and slabs made of ceramic material, sheets of paper or cardboard and sheets of cloth are considered slab-shaped manufactured articles which can be decorated by means of the present invention.
  • the decoration of slab- shaped manufactured articles consists of applying pigments to the visible face of the tiles, made of unfired or partly fired ceramic material, which are then completely and definitively stabilized by firing in a kiln.
  • the decoration of the slab- shaped ceramic manufactured articles can be carried out using various methods and, currently, the use of digital printers is widespread.
  • the decoration of slab- shaped ceramic manufactured articles using digital printers involves the application of special ceramic inks, which consist of mixtures of powdered dyes (mineral oxides, or metal oxides, or metals with complex structures), with a very fine grain size, suspended in a special solvent or other carrier.
  • special ceramic inks consist of mixtures of powdered dyes (mineral oxides, or metal oxides, or metals with complex structures), with a very fine grain size, suspended in a special solvent or other carrier.
  • the digital printers for the decoration of tiles made of ceramic material of known type usually comprise a plane of forward movement on which the ceramic manufactured articles to be decorated move forward and a plurality of printing heads facing the plane of forward movement and provided with nozzles dispensing the ceramic ink on the visible face of the ceramic manufactured articles.
  • the plane of forward movement is usually composed of a conveyor belt which is moved along a substantially horizontal direction thanks to pulleys or motor- driven rollers.
  • the printing heads spray ceramic ink onto the visible face of the slab- shaped ceramic manufactured articles according to a previously established pattern.
  • the printing heads are mounted on top of the plane of forward movement in a fixed position so as to cover the entire width of the plane of forward movement and be able to decorate the slab- shaped ceramic manufactured articles of any size, according to an operating mode commonly known as “single pass”.
  • the printing heads are, in fact, usually mounted on a holding bar placed on top of the plane of forward movement at a distance of a few centimeters from the plane itself.
  • the replacement operations of the printing heads and/or the capping operations are quite frequent, since they are to be carried out not only to adjust or clean any heads that are not perfectly functional but also to modify the printing area, i.e. the number and arrangement of the printing heads, which may vary depending on the size of the slab-shaped ceramic manufactured articles to be decorated; therefore, each time the size of the tiles in production is changed, it may be necessary to intervene on the printing heads.
  • some digital printers have all the printing heads mounted on a sliding drawer; when maintenance/capping operations are required, the drawer is removed from the machine taking the printing heads with it, allowing them to be replaced and/or cleaned and/or capped more easily.
  • the main aim of the present invention is to devise a digital printer for the decoration of slab-shaped manufactured articles, which allows carrying out in a practical, easy and functional manner the maintenance and/or capping operations of the printing heads.
  • a further object of the present invention is to devise a digital printer for the decoration of slab-shaped manufactured articles which allows avoiding stopping the manufacturing plant or at least reducing the downtime thereof.
  • the object of the present invention is to devise a digital printer for the decoration of slab-shaped manufactured articles which allows lowering the production costs and the retail price of the finished products.
  • Another object of the present invention is to devise a digital printer for the decoration of slab-shaped manufactured articles which allows the mentioned drawbacks of the prior art to be overcome within a simple, rational, easy and effective to use as well as affordable solution.
  • Figure 1 is an axonometric view of the printer according to the invention.
  • Figure 2 is a side view of the printer according to the invention.
  • Figure 3 is an axonometric view, on an enlarged scale, of a detail of the printer according to the invention.
  • Figure 4 is a plan view of a detail of the printer according to the invention, working according to a first operating mode
  • Figure 5 is a plan view of a detail of the printer according to the invention, working according to a second operating mode.
  • reference numeral 1 globally indicates a digital printer for the decoration of slab-shaped manufactured articles.
  • the digital printer 1 is particularly configured to decorate large- size slab- shaped manufactured articles M (e.g. with sides longer than 2 m), but can also be used to work with smaller sizes.
  • the digital printer 1 comprises at least one basic frame 2, for the support onto the ground, with which at least one line of forward movement 3 of the slabshaped manufactured articles M is associated.
  • the line of forward movement 3 is adapted to move the slab- shaped manufactured articles M along a direction of forward movement A.

  • the digital printer 1 comprises automatic means of fine adjustment, not shown in detail in the figures, which adjust the lifting and lowering of the supporting set 4 depending on the thickness of the slab-shaped manufactured articles M.
  • the supporting set 4 is placed in the proximity of the line of forward movement 3; for the decoration of thick slabshaped manufactured articles M (e.g. with a thickness of 2 cm), on the other hand, the supporting set 4 is placed at a greater distance from the line of forward movement 3.
  • the automatic means of fine adjustment consist, e.g., of a micrometer-controlled electric motor or other similar system.
  • the supporting set 4 is associated with at least one guidance unit 6 arranged at least partly on top of the line of forward movement 3 and defining a movement path Pl, P2, P3, P4.
  • a plurality of printing sets 7 is mounted on the guidance unit 6, which printing sets are movable in a sliding manner along the movement path Pl, P2, P3, P4, individually and independently of each other, between at least one working position, wherein the printing sets 7 are arranged on top of the line of forward movement 3 for the dispensing of ink on the slab- shaped manufactured articles M, and at least one home position.

  • the printing sets 7 may move along the movement path Pl, P2, P3, P4, which is also shaped in a closed loop, either in one direction of travel or in the opposite direction.

  • the guidance unit 6 comprises at least one linear magnetic motor device 8 provided with a plurality of movable sliders 9 on which the printing sets 7 are mounted.
  • the linear magnetic motor 8 in actual facts, consists of an electric motor wherein the rotor and the stator, instead of being circular, are deployed along a linear direction and, instead of generating a mechanical torque, produce a force.
  • the linear magnetic motor device 8 is, e.g., integrated along the guidance unit 6 and the movable sliders 9 to produce a magnetic field capable of setting the movable sliders 9 in motion, as well as the printing sets 7 mounted thereon, along the guidance unit 6 and blocking them in the desired positions.
  • the adjustment of the movement and of the blocking of the movable sliders 9 is micrometric, i.e. the linear magnetic motor device 8 is adapted to position the movable sliders 9 and the printing sets 7 along the guidance unit 6 with precision.
