Definitions

  • the invention relates to a printing machine for printing textiles with a machine bed, at least one conveyor device arranged on the machine bed for conveying at least one textile along a processing path, at least one priming device arranged on the machine bed for applying a primer paint over a surface area of the textile on which a Print motif is to be provided, and at least one printing device arranged on the machine bed with at least one digital print head for printing the print motif, according to the preamble of claim 1.
  • the invention further relates to a method for printing textiles, in particular with such a printing machine, in which at least one textile is conveyed by means of at least one conveyor device on a machine bed along a processing path, along the processing path on the textile on at least one priming device at least one primer paint over a large area a motif area of the textile is applied to which a print motif is to be applied, and the primed motif area for forming the print motif is printed on at least one printing device along the processing path with at least one digital print head, according to the preamble of claim 7.
  • the pretreatment fluid is not a color, but a preferably transparent liquid which is used to penetrate the fibers of the textile fabric and to pretreat them in such a way that undesired flow of the printing inks to be applied later is counteracted.
  • the pretreatment usually takes place in a separate station, preferably on a separate machine.
  • the textile is dried under the influence of heat, which can be done by means of radiant heaters or heating plates.
  • a primer color in particular a white color
  • the primer color can be applied with the same print head as the subsequent colors or with a separate print head.
  • the aim is to apply a print motif that is as precise and sharp as possible to the textile on the three-dimensional fabric structure of the textile.
  • the invention is based on the object of specifying a printing machine and a method for printing textiles with which a high quality print motif can be applied to a textile in a particularly efficient manner.
  • the printing machine according to the invention is characterized in that at least one press device is arranged between the priming device and the printing device along the processing path, which press device is used for pressing the Motif area is formed with the applied primer paint, and that the textile can be transported by means of the at least one conveyor device from the primer device to the press device and from the press device to the printing device.
  • a basic idea of the invention can be seen in applying a priming color in a priming device and then pressing this in a press station before printing with the actual print motif.
  • a smoothed motif area can be created in particular on a partial area of the textile.
  • the three-dimensional structure of the fabric of the textile is leveled and leveled to a considerable extent by the applied primer paint and the subsequent pressing, so that the actual print motif can subsequently be applied to this leveled motif area. Since the macroscopic three-dimensional fabric structure in the motif area is reduced or even largely eliminated, the print motif can be applied with particularly great precision and sharpness of the contours. Also, the step of pressing the primer paint before printing increases the longevity of the applied print motif.
  • pressing in the printing machine can be carried out with any suitable press device, for example with a press roller.
  • the press device has at least one press plate which can be heated.
  • the pressure plate has a size which corresponds at least to the size of the motif area.
  • the press plate can preferably be heated to a defined press temperature, which is in particular between 60 ° C. and 150 ° C., depending on the primer color used.
  • the textile is preferably clamped and pressed between a lower press plate or base plate and an upper press plate.
  • a preferred embodiment of the printing press according to the invention consists in that the primer device has at least one application nozzle for applying the primer paint.
  • the one or more application nozzles can be arranged in a print head which extends statically over the motif area of the textile to be primed or which can be moved transversely to the direction of movement of the textile.
  • the at least one conveying device can have a single pallet or a plurality of pallets, which each receive a textile and are moved in a linearly reversing or rotating manner along the processing path.
  • a particularly preferred embodiment of the invention can be seen in the fact that at least two parallel, adjacent conveyor devices are provided, and that the at least one priming device and / or the at least one printing device for each conveyor device have the same position in relation to the respective processing path.
  • the conveying devices can also have linearly reversing moving pallets or revolving conveyor belts. In the case of a twin arrangement of this type with two conveyor devices lying next to one another, efficient use of personnel and also efficient use of the processing units on the priming device or the printing devices can be achieved.
  • the adjacent priming devices and / or printing devices each have a common guide bar above the conveying device, along which application nozzles for the primer paint and / or print heads of the printing devices are mounted transversely to the processing path.
  • the application nozzles and / or the print heads are mounted on a respective common guide bar in such a way that they can basically process a textile both on the first conveyor device and on the second conveyor device. This allows a particularly efficient use of the processing units and also allows further operation of the printing machine, even if, for example, a print head on one of the conveying devices fails because this function can also be carried out by the second print head on the conveyor.
  • a preferred embodiment of the invention consists in that the priming device and the printing device are formed in one station.
  • the priming device and the printing device can therefore be formed at the same location, the press device being spaced therefrom.
  • the textile is first provided with a primer color by the primer device, the textile thus processed being conveyed to the press device by the conveyor device.
  • the textile is then conveyed back to the first processing location, the textile then being printed by the printing device.
  • the primer paint can be applied using the same print heads that are provided for the printing inks.
  • the invention is characterized in that the primed motif area of the textile is pressed by means of at least one press station, which is arranged between the at least one priming device and the at least one printing device, before the print motif is printed.
  • the method can in particular be carried out by the previously described printing press according to the invention.
  • the advantages described above relating to the application of the print motif in high quality can be achieved.
  • the primer color can be selected depending on a basic color of the textile to be printed.
  • the purpose of the primer is to ensure that an intense basic color of the textile does not impair the colors of the print motif to be printed.
  • a particularly advantageous embodiment of the invention is that the primer color is white. In this way, a basic color of the textile, even a black color, can be covered reliably.
  • the primer paint is applied with a layer thickness which can be between 10 ⁇ m and 500 ⁇ m.
  • filaments protruding from the fibers are covered by a primer paint and are incorporated into the applied primer layer at least during the subsequent pressing.
  • the primer color can only extend on one upper side of the fibers and threads of the motif area of the textile.
  • the primer paint can also cover the pores or mesh openings of the textile as a whole, so that a largely closed surface is then formed.
  • the motif area can thus form a flat surface after pressing, which is free of mesh openings or has mesh openings that are still exposed.
  • an advantageous embodiment of the method according to the invention consists in that the applied primer paint forms a continuous base surface, which is preferably flat, when pressed onto the motif area of the textile.
  • the base has a flat surface that is printed.
  • the motif area is pretreated with a treatment medium to a degree that is less than the degree of pretreatment for direct application of a printing ink.
  • the textile is preferably pretreated with a pretreatment fluid, but only about a third to a half of the pretreatment fluid is required, as in a normal textile printing process.
  • the primer paint also helps to seal the individual fibers and thus counteracts the flow of the printing inks through the fiber structure.
  • a pretreatment with a pretreatment fluid is dispensed with altogether.
  • a plurality of printing inks are printed on, one of which is white.
  • a white primer paint can thus be applied with the primer device. Then, after pressing, a white printing ink can be applied, which ensures what is known as highlighting in the motif area.
  • the pressing of the motif area of the textile after priming and before the actual printing can in principle take place in any desired manner, for example by means of press rollers. According to a further development of the invention, it is particularly preferred that the pressing takes place with a press plate which is heated to a defined temperature range.
  • the press plate has a flat contact surface, which is preferably provided with an appropriate coating to prevent paint from sticking.
  • a corresponding abutment plate or base plate, which is not heated or is also heated, can be provided below the textile.
  • the press plate applied to the print motif from above is preferably electrically heated to a temperature range between 60 ° C and 150 ° C. This not only ensures that the applied primer layer is smoothed out well, but also that the primer paint dries and hardens quickly.
  • the invention is further explained below with reference to a preferred exemplary embodiment which is shown schematically in the accompanying drawing.
  • the drawing shows a schematic plan view of a printing press according to the invention.
  • a printing press 10 is shown with a machine bed 12 that is rectangular in plan view.
  • two parallel, juxtaposed, belt-shaped conveyor devices 20a, 20b are arranged in a longitudinal direction.
  • the conveying devices 20 can be moved from a front input area in a movement or processing direction, which are each indicated by an arrow, to an end or removal area.
  • the textiles to be processed on the conveying device 20 first reach a priming device 30.
  • the priming device 30 has a portal-like guide bar 34 which is arranged above the conveying devices 20 on the machine bed 12.
  • a first application head 32 for the first conveyor 20a and a second application head 32 for the second conveyor 20b for applying a primer paint to a motif area of the textile are arranged on an underside of the guide bar 34.
  • the application heads 32 are designed with one or more application nozzles which are directed downwards towards the textile.
  • the application heads 32 are mounted such that they can be moved transversely to the conveying direction or the processing path of the textile along the guide bar 34.
  • the application heads 32 can thus cover the entire width of the conveyor device 20 and apply the primer paint in this area.
  • the application head 32 of the first conveying device 20a can also extend beyond the second Conveyor device 20b are moved in order to replace or support the application head 32 provided there if necessary.
  • the textile with the primed motif area is conveyed further in the conveying direction to a press device 50.
  • a height-adjustable press plate 52 is arranged on the press device 50 for each conveyor device 20, which press plate 52 can preferably be pressed with a pneumatic or hydraulic cylinder from an upper retraction position into a lower processing position, in which the press plate 52 is pressed onto an upper side of the textile on the conveyor device 20 becomes.
  • the press plates 52 can also be mounted on a portal-like guide bar 54 above the conveyor device 20 on the machine bed 12.
  • the press plates 52 are preferably electrically heated so that the motif area provided with the primer paint can be pressed on the textile and dried at the same time.
  • a particularly flat motif area can also be produced on a coarsely woven textile.
  • the textile is then conveyed onward to one or more printing devices 40 by means of the conveyor device 20.
  • the printing press 10 has only a single printing device with a portal-like guide bar 44, which is mounted on the machine bed 12 above the conveying device 20.
  • two print heads 42 with print nozzles are arranged on an underside of the guide bar 44 of the print device 40, through which a print motif can be applied to the motif area of the textile in a basically known manner by digitally controlling the print nozzles.
  • the print heads 42 can also be adjusted along the guide bar 44 transversely to the processing path of the textile, so that a print head 42 for the first conveyor 20a can replace the print head 42 for the second conveyor 20b.
  • the print head 42 of the second conveyor device 20b can also replace or support the print head 42 of the first conveyor device 20a.
