Definitions

  • the present invention relates to a printing machine with inkjet printer or the like, particularly for decorative printing of easily deformable sheet-like products such as fabrics, hides, synthetic films or other products.
  • this method has the advantage of requiring no intervention for replacement or adaptation, and further allowing to utilize the extreme versatility and speed that are typical of digital technology.
  • Another problem is the behavior of the product being printed, i.e., the fabric.
  • the fabric is in fact rested on a supporting surface and is made to advance gradually, in step with the actuation of the printing head, by means of a set of wheels that press on the fabric and move it by friction.
  • This advancement often causes a transient deformation of the fabric that inevitably penalizes printing precision. Moreover, during advancement the fabric may shift accidentally.
  • the aim of the present invention is to solve the problems noted above by providing a printing machine that allows to print, with fully satisfactory results, easily deformable sheet-like products such as fabrics, hides, synthetic films or other products by using an inkjet printer or the like.
  • an object of the invention is to provide a printing machine that allows to use the advantages of printing with digital technology also for the printing of fabrics, hides, synthetic films or other deformable products.
  • Another object of the invention is to provide a printing machine that thanks to its high versatility allows economically convenient decorative printing of products even in small runs.
  • a printing machine with inkjet printer or the like particularly for decorative printing of easily deformable sheet-like products such as fabrics, hides, synthetic films or other products
  • a main structure that supports means for supporting and moving the product to be printed, which can be actuated in order to produce an advancement of said product along an advancement direction, and at least one inkjet printing head, which can move on command with a reciprocating motion along a printing direction that is substantially perpendicular to said advancement direction in order to print a region of the product that faces said printing head
  • said support and movement means comprise a belt-type conveyor element that runs along a path in which one portion faces the work area of said printing head and forms, with one of its faces, at least along said portion, a supporting surface for said product.
  • the machine generally designated by the reference numeral 1, comprises a main structure 2 that supports supporting and movement means 3 for supporting and moving the product 4 to be printed; said means can be actuated in order to cause the advancement of the product 4 along an advancement direction, indicated by the arrow 5.
  • the machine comprises at least one printing head 6 of the inkjet type or the like, which can move on command with a reciprocating motion along a printing direction 7, which is substantially perpendicular to the product advancement direction 5, in order to print the region of the product 4 that in each instance faces the printing head 6.
  • the printing head 6 can slide along a guiding bar 8, which is fixed to the main structure 2 of the machine.
  • the printing head 6, with the corresponding elements required for its operation, such as for example a motor that is actuated to cause the reciprocating movement of the printing head 6 along the bar 8, is not described further for the sake of simplicity, since it is of a known type, for example of the type currently used to print fabric samples or more generally for computer-controlled printing of graphic output on a paper medium.
  • the support and movement means 3 comprise a belt-type conveyor element 9, constituted by a conveyor belt or ribbon, which runs along a path that faces, with one of its portions, the work area of the printing head 6.
  • the conveyor element 9 forms, with one of its faces, at least at the portion that faces the work area of the printing head 6, a supporting surface for the product 4.
  • the product 4 can be simply rested on the conveyor element 9. Owing to the fact that the product 4, differently from what occurs with known types of printing machine with inkjet printing head, is not subjected to traction during its advancement, deformation of the product 4 as a consequence of its feeding during printing is avoided with absolute certainty.
  • the face of the conveyor element 9 that is meant to make contact with the product 4 in order to support it and feed it is adhesive-coated, so that the product 4 is firmly anchored to the conveyor element 9 during its advancement and during printing, thus avoiding any possibility of deformation of the product 4 or of random movements of said product 4 with respect to the conveyor element 9.
  • the conveyor element 9 has a closed shape and winds around at least two rollers 10 and 11 that have horizontal and mutually parallel axes and are orientated at right angles to the advancement direction 5.
  • At least one of the rollers 10, 11 is connected to a motor 12, which can be actuated in order to cause the advancement of the conveyor element 9.
  • rollers 10 and 11 are preferably arranged so that their axes lie on a substantially horizontal plane and have mutually identical diameters, so that the upper portion of the conveyor element 9, meant to support the product 4, lies on a substantially horizontal plane and faces, with one of its portions, the underside of the guiding bar 8 along which the printing head 6 moves.
  • a plate-like supporting element 13 is conveniently arranged below the upper portion of the conveyor element 9 over at least one portion of its extension that also affects the work area of the printing head 6; said supporting element is fixed to the main structure 2 and forms a supporting surface for the upper portion of the conveyor element 9.
  • presser means 14 which are meant to make the product 4 adhere firmly to the adhesive layer of the conveyor element 9.
  • Said presser means 14 can be constituted by a presser roller 15, which is orientated so that its axis is parallel to the axes of the rollers 10 and 11 and is supported by the main structure 2.
  • Said presser roller 15 faces the upper portion of the conveyor element 9 and optionally can be movable toward or away from the conveyor element 9 along the direction 16 in order to facilitate the deposition of the initial part of the product 4 on the conveyor element 9.
  • the presser roller 15 can be pushed toward the conveyor element 9 by means of springs, weights, fluid-driven cylinders or other means of a known type.
  • the presser roller 15 can be arranged above the roller 10 or above a region of the conveyor element 9 that is supported by the supporting element 13, so that its pressure on the conveyor element 9 is contrasted adequately in order to achieve the maximum effect in pushing the product 4 against the conveyor element 9.
  • the conveyor element 9 can be made, for example, of vulcanized rubber reinforced with a textile core, so as to have high dimensional stability and adequate mechanical strength.
  • the adhesive coating of the face of the conveyor element 9 that is meant to make contact with the product 4 can be achieved by spreading a layer of permanent adhesive of a known and easily commercially available kind.
  • the motor 12 and the motor that drives the printing head 6 along the direction 7 are functionally interconnected so that the actuation of the printing head 6 and of the conveyor element 9 are synchronized according to the printing requirements.
  • the actuation of the entire machine can be managed by a control and monitoring element 17 of the programmable electronic type, such as for example a computer, which controls and monitors the actuation of the conveyor element 9 and of the printing head 6 according to preset programs.
  • a control and monitoring element 17 of the programmable electronic type such as for example a computer, which controls and monitors the actuation of the conveyor element 9 and of the printing head 6 according to preset programs.
  • the movement of the printing head 6 and of the conveyor element 9 can be controlled by means of encoders connected to the control and monitoring element 17 and arranged on the shafts of the motors that actuate said elements.
  • the product 4 to be printed is constituted by a rolled-up continuous element, such as for example a fabric
  • a roll holder for supporting the product in roll form to be printed, which is gradually unrolled, and it is possible to provide, at the output of the machine, a motorized takeup roll 18 on which the printed product is gradually wound.
  • the product 4 to be printed is simply rested on the upper portion of the conveyor element 9.
  • the product 4 to be printed or the supporting element on which it is placed is gradually made to adhere to the upper face of the upper portion of the conveyor element 9 by the presser roller 15.
  • the advancement of the upper portion of the conveyor element 9 along the advancement direction 5 places in each instance a portion of the product 4 under the work area of the printing head 6, which prints it, according to a program that is preset according to the ornamental pattern or design to be printed.
  • the printed product 4 exits from the machine and is optionally collected on the takeup roller 18.
  • the product 4 can separate from the conveyor element 9 after printing either spontaneously, as a consequence of the change of direction of the conveyor element 9 that winds onto the roller 11, or can be assisted, optionally by means of a separator bar or blade.
  • Any adhesive coating of the face of the conveyor element 9, by reinforcing the adhesion of the product 4 to the conveyor element 9, further ensures the absence of deformations and/or movements of the product 4.
  • the machine according to the invention fully achieves the intended aim, since it allows to print with excellent precision easily deformable products such as fabrics, hides, synthetic films or other products by using an inkjet printer or the like, and therefore with the possibility to utilize all the advantages, in terms of speed and versatility, of the digital technology used to control these kinds of printer.
  • the machine according to the invention has been conceived particularly for printing deformable sheet-like products, such as fabrics, hides, synthetic films or other similar products, it can be used nonetheless also to print other kinds of product that do not have the problem of avoiding deformations induced by traction, such as for example paper, but in which one wishes to avoid with absolute certainly accidental movements of the product during feeding and/or printing.
  • the materials used, as well as the dimensions, may be any according to requirements and to the state of the art.
