Definitions

  • the invention relates to a device for drying printed products according to the preamble of the main claim.
  • a device is known in which a laser light source generates a laser beam.
  • This laser beam is directed via a rotating polygon mirror onto a printed product, which is carried out continuously under the laser beam. Due to the rotating polygon mirror, the laser beam oscillates across the width of the printed product and causes heating and thus drying of the printing ink applied to the printed product.
  • a disadvantage of this known device can be seen in the fact that the laser beam only heats the printed product selectively. This requires a very high energy density, since the point of incidence of the laser beam must be guided over the printed product at high speed in order to cover its entire area. In addition, a drive device is required for the polygon mirror.
  • the invention is therefore based on the object of avoiding negative influences on the printing press caused by the radiation device due to its heat loss and to achieve the fastest possible drying of the ink with optimal use of the radiation energy.
  • a major advantage of the solution according to the main claim is to be seen in the fact that unnecessary heating in the printing press is avoided by arranging the radiation device outside the printing press.
  • a radiation device can be a laser beam source, for example.
  • the laser beam is transmitted by means of suitable transmission means which have a low power loss. It is furthermore advantageous to simultaneously radiate the energy over the entire width or a partial area of the surface Let printed products hit. This means that the radiation energy does not hit them point by point, but rather linearly, which results in a better drying effect and a higher drying speed.
  • optical fiber cable is used as the transmission means.
  • Optical fibers can be used to bridge long distances between a radiation device and the place where the radiation energy is used. If this optical fiber cable consists of a large number of individual fibers, its end can be fanned out in a line, i.e. the individual optical fibers are separated into one or more rows that end above the surface of the printed copies. The width of such a row corresponds to the width of the surface to be dried.
  • a gas-filled tube is provided as a transmission means for the radiation energy. Nitrogen is expediently used as the gas filling. Such a pipe can also be used to achieve very long lines. To form a linear radiation energy, an optical beam splitter device is provided at the end of the tube.
  • UV inks recently used in offset printing harden when exposed to UV light. Compared to solvent-based inks, these inks have the advantage that they can be dried without unnecessarily heating the printed copy. It is therefore expedient and provided according to a further development of the invention to generate the radiation with a wavelength that is in the UV range.
  • this tube is provided with a UV-reflecting inner coating.
  • a UV-reflecting inner coating With such an inner coating, it is possible to lay the pipe as desired like an optical fiber. Deflecting mirrors and straight pipe routing are then not required.
  • the entire device can be integrated into a control circuit for controlling the radiation energy to be supplied. Since a printed copy is rarely printed over the entire area, but also very often has non-image areas, it is advantageous not to allow any radiation energy to strike the printed product or the printed sheet at the non-image areas. This means that radiation energy only needs to be supplied to the printing sheet where it is required due to the presence of ink to be dried.
  • the radiation energy is controlled by a control device.
  • This control device is supplied with information about color-guiding or non-color-guiding areas on the printed product via sensors. For example, the sensors are directed in the same way as the line of incidence of the radiation energy on the printed sheet and detect the ink application on this sheet. The signals generated by the sensors are fed to the control device, the control device using these signals to switch the intensity of the radiation energy.
  • an electronic memory can also be provided, in which the structure of the printed product, ie the distribution of ink-guiding and non-ink-guiding surfaces, is stored. Cyclic reading of the memory content with the control device is carried out in the same way Beam intensity or the switching of the radiation energy controlled.
  • the radiation device can be equipped with radiation sources that generate different wavelengths. This has the advantage that it is possible to dry inks that harden in different UV ranges. Depending on the color used, the corresponding UV ranges are selected and the radiation device is activated with the corresponding wavelength.
  • the schematic representation of a printing press 1 shows a sheet-fed offset printing press with a sheet feeder 2, four printing units 3, 4, 5, 6 and a sheet delivery unit 7.
  • the drive 8 of the printing press is an electric motor 9.
  • the sheet is transported along the transport path 21 (FIG. 2).
  • a suitable drying device has several components.
  • a first component is a device for generating radiation energy, which consists of a laser beam device 13.
  • Such a laser beam device contains an electronic control unit 14 and a laser tube 15. This laser beam device is known, for example, from "Lambda Physics Laser Beam Technology", information leaflet from Lambda Physiks GmbH, Göttingen, Germany.
  • the laser beam generated by the laser tube is fed into an optical fiber cable 16, 17, which consists, for example, of a bundle of optical fibers, as a further component.
  • the entire laser beam device 13 is arranged outside the printing press in a suitable housing.
  • the only connection between the laser beam device and the printing press is via the optical fiber cables 16, 17.
  • the ends of the optical fiber cable 16 are brought up to the transfer drums of the individual printing units and end just above the outer surface of these transfer drums.
  • the ends of the optical fiber cable 17 are to a chain delivery 18, which transports the printed sheets to the sheet delivery 7.
  • the printed sheets are then dried on both sides in the area of the chain delivery.
  • the ink or coating layer applied by the printing unit 6 is dried.
  • FIG. 2 An embodiment of the end of an optical fiber cable 16 is shown in more detail in FIG. 2.
  • a print sheet 19 is located on the transfer drum 12. This is held at its front end by means of a gripper 20 and transported along the transport path 21.
  • Above the Transfer drum 12 is arranged on a traverse 22, the end of the optical fiber cable 16.
  • the optical fiber cable 16 is split, ie the individual fibers of the cable are arranged so that they have a line running transversely to the transport direction of the sheet, form.
  • the laser beam emerging at the ends of the optical fiber cable 16 strikes the arc surface almost perpendicularly.
  • a plurality of laser tubes can also be arranged, each of which generates a laser beam of a specific wavelength.
  • the laser beams of different wavelengths are led to the individual printing units via separate or a common optical fiber cable. With this multiple laser, each printed color is optimally cured according to its absorption behavior and its curing properties.
  • a so-called UV excimer laser can also be used to generate the laser beam.
  • excimers are formed by an electrical discharge under certain discharge conditions. These are molecular complexes such as Xe2, which emit UV radiation when decaying.
  • Xe2 molecular complexes
