Definitions

  • the present invention relates to printing on panels intended for forming packaging boxes, proposing a machine for such a function with which the process of printing said panels can be carried out without the common limitations of a specific printing system, such as flexography, intaglio or ink projection, also allowing to carry out supplementary operations on such panels, such as dying, background application, painting, etc., without having to use multiple devices or facilities for such purpose.
  • a specific printing system such as flexography, intaglio or ink projection
  • MDF panels have a color and an absorption capacity that make it impossible to print with quality if a layer of background paint is not first applied so that the colors of the printing ink appear with the corresponding tone when they are applied.
  • the amount of product applied is key to obtaining correct results with competitive costs, as is the case of special effects inks (gold, silver and other metallic colored inks), the high cost of which requires correct metering, which is only possible with ink jet heads, which afford precision in the range of picoliters in the applied ink volume.
  • Ink jet printing allows in the same manner variable data that can be changed from piece to piece, for example bar codes, part number, manufacturing batch, packager, weights, etc.
  • patents EP 1 364 783 and ES 2,204,290 describe machines with successive print heads and a transfer conveyance of the pieces to be printed along a path with regard to the different heads, incorporating the application of a vacuum through the conveyor means itself for holding the pieces and adapting them against the mentioned conveyor means.
  • the invention proposes a machine developed with constructive and functional features that allow overcoming in a practical manner the drawbacks of the use needs of different printing techniques, achieving very important advantages for performing printing processes to be carried out.
  • This machine object of the invention comprises transporting the pieces to be printed along a path through the position of one or more print heads with the pieces being fed to said conveyor from an automatic feeder and the pieces being held on the conveyor means by means of applying a vacuum therethrough.
  • each print head of the machine is formed with an applicator roller, which can be of the direct printing type or by means of a blanket incorporated thereon, a holding system of an inking module being arranged in relation to said applicator roller, by means of a support on which it is possible to incorporate different types of inking modules, with an easy to assemble and disassemble holding.
  • the assembly support for the inking module consists of two parallel blocks, between which the print applicator roller and the component elements of the inking module are incorporated, said blocks of the assembly support being provided for such purpose with anchors for holding the component elements of different types of inking modules, allowing the inking module to be easily changed.
  • a machine is thus obtained with a modular concept in terms of the inking system of the print applicator roller, such that it allows using different types of inking modules according to the printing process to be carried out by means of a fast and easy replacement of the inking module in each print head, being able to use flexography, intaglio, ink jet or single roller application modules in order to combine any technique depending on the desired print.
  • Said machine object of the invention therefore has clearly advantageous features having its own identity and preferred nature in relation to conventional solutions for the application function it is intended for.
  • the object of the invention relates to a machine intended for printing such types of print applied on panels used to form packaging boxes for fruits, vegetables, bottled products, etc., being carried out such that it allows applying different printing techniques by means of simply changing the inking modules of the print applicator roller.
  • Said object of the invention can be applied in printing machines like the one shown in Figure 1 , formed by an automatic feed (1) feeding the panels to be printed to a conveyor (2) taking them along a path through one or more print heads (3), a vacuum bin (4) being arranged in relation to the conveyor (2) which provides a suction through perforations of the conveyor (2) itself for holding the panels to be printed thereon.
  • each print head (3) consists, as shown in Figure 2 , of an applicator roller (5) by means of which the application panels (6) are printed on either directly or by means of a blanket incorporated on the roller, a holding arrangement for holding the different types of inking modules (7.1, 7.2, 7.3, 7.4) being provided in relation to said applicator roller (5), which inking modules can be replaced according to the printing technique involved in each case.
  • Said arrangement allows determining, for example, a flexographic printing system, incorporating an inking module (7.1), as shown in Figure 3 , wherein the ink (8) is fed from a closed chamber (9) by means of an engraved roller (10) in contact with the applicator roller (5), which in turn makes contact with the panels (6) to be printed.
  • a flexographic printing system incorporating an inking module (7.1), as shown in Figure 3 , wherein the ink (8) is fed from a closed chamber (9) by means of an engraved roller (10) in contact with the applicator roller (5), which in turn makes contact with the panels (6) to be printed.
  • An intaglio printing system can likewise be provided, incorporating an inking module (7.2), as shown in Figure 4 , wherein the ink (8) is fed by means of an engraved roller (11) on which a metering blade (12) is supported due to the contact of said engraved roller (11) with the applicator roller (5), which in turn makes contact with the panels (6) to be printed.
  • a system can be easily replaced by another one in any of the print heads (3) of the machine by means of removing the inking module that is incorporated and assembling the inking module of the system to be applied, a support (16) being provided for such purpose, according to Figure 2 , which can hold any of the inking modules (7.1, 7.2, 7.3, 7.4) for the different application systems.
  • the support (16) for holding the inking modules is envisaged formed by two blocks (16.1, 16.2) arranged parallel to one another, the applicator roller (5) being arranged between said blocks by means of inserting the ends of its axle (5.1) in respective holes (17) of the mentioned blocks (16.1, 16.2) forming the support (16).
  • Said blocks (16.1, 16.2) of the support (16) further have rods (18) for holding the ink chamber (9) of the system of Figure 3 , as can be seen in Figure 7 , or for holding the projecting heads (15) of the system of Figure 6 , as can be seen in Figure 10 , said blocks (16.1, 16.2) likewise defining gaps (19) in which the roller (11) of the system of Figure 4 can be held by means of supports (20), as shown in Figure 8 , or in which the rollers (13 and 14) of the system of Figure 5 can be held by means of supports (21), as shown in Figure 9 , guides (22) being formed in said gaps (19) for the assembly of the roller (10) of the system of Figure 3 by means of respective supports (23), as shown in Figure 7 .
