Definitions

  • the invention relates to a printing machine for direct printing of containers according to the preamble of claim 1 and a curing unit for printing ink on containers according to the preamble of claim 7 and a method for direct printing of containers according to the preamble of claim 10.
  • Radiation-reactive inks that cure by exposure to UV light are increasingly being used for direct printing of containers.
  • radiation-reactive printing inks are cured in the area of the printing press. This process is also known as pinning or fishing.
  • the printing units are assigned to curing units with radiation sources for irradiating the previously printed container areas.
  • the edge sharpness of imprints can be improved, since excessive bleeding of the printing inks is prevented.
  • the hardening of white background ink before overprinting with the actual process colors such as yellow, magenta, cyan and black.
  • the time interval permitted in each case between the imprint and the curing determines the extent to which the ink runs. In this case, it is generally desirable to control the extent of the color progression as flexibly and reproducibly as possible even when the printing press is running at different speeds and / or different printing inks and / or different container materials.
  • a generic printing machine is known from DE 10 2013 217 659 A1.
  • curing units are provided for irradiating the light of printing ink on containers in the periphery of a container carousel.
  • the curing units can be adjusted radially with respect to the carousel by means of a linear drive in order to adjust the irradiance resulting on the container surface.
  • the curing unit can thereby be adapted to different container cross sections.
  • Suitable curing radiation is, for example, UV light, which according to DE 10 2012 209 085 A1 is emitted by LED lamps and deflected by means of optical elements, such as cylindrical lenses or the like, onto the container areas to be irradiated can. Also, such optical elements allow a change in the light distribution on the surface to be irradiated, for example by variation in distance between the UV LED lamp and the optical element.
  • a disadvantage of the described printing machines and curing units is that the time interval between expression and hardening also changes with a change in the transport speed of the carousel, for example when starting up and shutting down the printing press. Another disadvantage is that you can adjust this time interval or only with considerable effort to changing environmental conditions, inks and / or container materials. As a result, the flowability of the printed inks prior to cure is inadequate in many cases.
  • this is for direct printing of containers and includes: a carousel for the continuous transport of the containers; on the carousel stationary arranged printing units with printheads for radiation-reactive inks; and individual and / or more of the printing units associated with curing units with respect to the carousel adjustable radiation sources for curing the printing inks.
  • the radiation sources are adjustable / movable / pivotable in the transport direction of the containers.
  • an adjustment in the transport direction is meant a positioning of the radiation sources by driving and / or pivoting substantially along and / or tangential to the transport path of the containers, in particular with respect to the pitch circle of the carousel. This is to be understood in contrast to an adjustment or positioning of the radiation sources away from or towards the transport path.
  • the transport distance between the imprint on the printing units and the curing of the associated curing unit can be adjusted specifically.
  • the respective actual time interval between printing and curing can be flexibly adapted to an example, material-specific and / or temperature-specific predetermined time interval between printing and curing.
  • the desired time interval between printing and curing depends, for example, on the type of radiation-reactive ink, on the container material to be printed and / or on the ambient temperature prevailing during the printing.
  • Driving the curing units in the direction of transport refers to changes in the transport distance from the printing unit, as opposed to exclusively adjusting the irradiation distance of the light sources from the containers.
  • the light sources are preferably UVA LED emitters with emission maxima of at most 400 nm, in particular from 365 to 395 nm.
  • the printing press further comprises electronic control for automatically adjusting transport distances between associated printheads and radiation sources in dependence on the transport speed of the containers and on predetermined or calculated target time intervals between printing and curing of the printing inks.
  • the desired time intervals for a specific printing ink and a specific container material are predetermined and / or calculated for a specific ambient temperature.
  • the actual transport speed of the containers is used by the controller to calculate a transport distance suitable for the respective transport speed and the predetermined target time interval.
  • the controller then instructs the curing unit to approach a suitable irradiation position of the irradiation sources substantially in or opposite to the transport direction to adjust the calculated transport distance.
  • the actual time interval between printing and curing of the inks can be adjusted to the applicable target time interval even with variations in the transport speed, such as when starting and shutting down the printing press.
  • control is designed for color-specific specification of the desired time intervals for individual printing units.
  • optimized flow properties of the respective printing ink can then be reproducibly and flexibly produced for the color components of a color model, such as, for example, CMYK, applied successively in layers.
  • the radiation intensity of the radiation sources and / or their duty cycle per container are also controllable.
  • LED emitters with adjustable relative radiation power of, for example, at most 10 to 100% are particularly suitable.
  • LED spotlights can be turned on and off within a few milliseconds to irradiate the imprints each in a treatment cycle over a predetermined period.
  • the intensity and duration of the curing can be adapted specifically to specific color types and container materials, as well as to different transport speeds of the containers and / or the ambient temperature.
  • the printing press preferably comprises groups of docking stations arranged in pairs for the printing units and an immediately adjoining hardening unit. In the periphery of the carousel then several groups of two docking stations and one Anhärtungshow are arranged in the transport direction one behind the other.
  • a first group could be designed to imprint and harden a white background color.
  • An adjoining second group could be designed to imprint and harden two color components of a color model, in particular first yellow and then magenta.
  • a subsequent third group could be designed to print and harden two further color components of the color model, in particular first cyan and then black.
  • a fourth group could follow to print and harden a further layer of white background ink.
  • a fifth group could be present for printing and curing black ink or any color component of the color model.
  • multicolor prints in individual layers of color can be printed on one another in a controlled manner and hardened, as well as special overprints, such as, for example, labeling fields.
  • individual docking stations can remain unoccupied, for example, if only a single color layer is required for a covering printing base for a white base print. If, on the other hand, two successively applied white color layers are required for sufficient coverage of the container material, two adjacent printing units of a group can be put into operation.
  • the printing units required for certain printing tasks can be efficiently / flexibly arranged / activated on the printing machine and the curing units can be positioned at a suitable transport distance.
  • the printing units each comprise at least two, in particular at least three print heads for vertically overlapping partial imprints.
  • the radiation sources cover the vertical pressure range of all partial imprints, in particular a vertical range of at least 120 mm.
  • two printheads are positioned one above the other and a third printhead vertically in between and overlapping with the other two printheads, preferably upstream in the transport direction of the other two printheads.
  • the transport distance between printing and curing can then be determined, for example, as the distance between the superimposed print heads and the associated curing unit.
  • container side walls with commercially available dimensions in the vertical direction can be continuously provided with printed images.
  • the individual print layers are then printed continuously and cured.
  • the object is also achieved with a Anhärtungshow according to claim 7. Accordingly, this is for the curing of ink on containers in a printing machine according to at least one of the embodiments described above.
  • the curing unit comprises a radiation source for irradiating an imprint on the containers with an annealing radiation and a frame with which the radiation source can be moved relative to a transport path of the containers.
  • the frame for adjusting / driving / pivoting the radiation source in the transport direction of the container is formed.
  • Printing machines can also be retrofitted with such curing units. In conjunction with existing printheads and the carousel of the printing press can thus achieve the advantages described above.
  • the frame comprises a motor-driven linear drive, in particular in the form of a cross slide, for positioning the radiation source in the transport direction.
  • a linear drive for example, be aligned substantially tangentially with respect to the transport path of the container.
  • the linear drive can be oriented so that it includes in its adjustment with the transport path of the container acute angle of at most 10 °.
  • the cross slide can have an arc-shaped course adapted to the pitch circle of the carousel, for example by means of a correspondingly curved guide and a carriage running along it.
  • the radiation sources can be adjusted particularly flexibly into a suitable irradiation position in the transport direction and to a suitable irradiation distance, which is defined in particular radially with respect to the carousel.
  • the frame for motorized adjustment of a transport distance between an irradiation position of the radiation source and a printing position of an associated print head is formed in particular along a transport path of the container.
  • the frame for this purpose comprises an automatically controllable drive for setting the irradiation position in the transport direction and preferably also orthogonal thereto, ie in the main irradiation direction.
  • the stated object is also achieved by a method according to claim 10. Accordingly, this is used for direct printing of containers during their continuous transport on a carousel. Furthermore, radiation-reactive inks are printed in layers by means of stationary print heads and radiation sources and hardened. According to the invention, actual time intervals between imprinting and associated hardening as a function of a transport speed of the containers are adjusted by adjusting the radiation sources in the transport direction of the containers to desired time intervals between printing and associated hardening. Thus, a desired flow behavior of the printing inks can be achieved even with varying transport speed.
  • a layered imprint is to be understood as meaning that individual color layers of a white background and / or individual color components of a color model are applied one above the other by means of separate printing units in succession and depending on the printing motif.
  • the hardening takes place either after the application of a single coat of paint or after the application of two coats of paint.
  • transport distances defined between the irradiation positions of the radiation sources and the printing positions of the assigned print heads are automatically readjusted in the event of a change in the transport speed and / or an ambient temperature.
  • Actual values of the transport speed and the ambient temperature can be easily determined during the current printing operation. This facilitates continuous control of the transport distances.
  • both actual time intervals between the imprint and associated hardening can be adapted to their respective desired values, as well as predetermined time intervals between imprint and associated hardening suitable for the respective prevailing conditions, in particular for a measured ambient temperature.
  • the desired time intervals are specified specifically for the container material to be printed and / or the applied ink.
  • Corresponding desired values can be stored, for example, in a central controller of the printing press and adjusted flexibly and reproducibly depending on the product to be produced. Thus, high quality imprints on different containers are possible with little retooling.
  • a radiation intensity and / or irradiation duration with hardening radiation is preferably set by machine as a function of the transport speed of the containers, ie by means of the controller.
