Definitions

  • the innovation relates to a device for cleaning ink-transferring cylinders within a rotary printing press.
  • the quenching device shown there essentially has at least one nozzle, but preferably a plurality of nozzles arranged next to one another, which can be connected with the means of a commercially available high-pressure cleaning system, and is arranged in the printing press over an area of the surface of the printing form in the printing form. The entire surface of the printing form can be erased while the printing form is rotated under the erasing device.
  • the nozzles of the quenching device are provided with an encapsulation which is open towards the printing form to protect the environment, the encapsulation defining a work space and being connected to a pump for disposing of the water introduced into the work space and the removed coating.
  • a gravure cylinder is known from EP 0 368 177 B1, in which a solid substance which can be liquefied by the action of energy is introduced in an amount inversely proportional to the amount of ink to be transferred into each well of a raw form.
  • an erasing device is used which liquefies the filling material in the cells by means of a heat source and removes them again by means of a wiping and / or blowing or suction device.
  • the object of the invention is now to provide a complete cleaning system for ink-transferring cylinders within a rotary printing press, with this a reactive deletion of ink-carrying layers, including the removal of filler materials from a gravure printing form, and a cleaning of all form and transfer cylinders of ink during the printing process or possible during printing breaks.
  • an entire cleaning system is constructed in the rotary printing press with which reactive extinction is possible of ink-bearing layers, including the removal of filler materials from a gravure printing form, and cleaning of all form and transfer cylinders from color is also possible during the printing process.
  • the extinguishing device presented in the introduction to the description can be used for this purpose, which is arranged axially across the width of the cylinder to be cleaned and from which the water with the paint and, if appropriate, the filling materials or organic substance parts can be sucked off.
  • a doctor blade is provided behind the extinguishing device for scraping off the cylinder surface from any excess moisture, which is preferably designed as a rubber doctor blade.
  • a drying device for the same purpose, namely to remove excess moisture from the cylinder surface, a drying device can be used, which can be in the form of an air knife or a dry roll.
  • any agent including a dry fleece, that removes any excess moisture from the cylinder surface after the cleaning process could be used.
  • a rubber-to-rubber printing unit 1 of an offset printing machine comprises printing plate 4 and rubber cylinder 3 in a known manner, as well as two inking units 5 and dampening units 6.
  • the printing form cylinder 4 can now be a cylinder which is imaged by means of a thermographic process with an ink-guiding layer and is suitable for offset printing and has an erasing device 8 which is employed in a known manner, but also can be a plate cylinder prepared for planographic printing.
  • an extinguishing device 7 is also provided for each of the transfer or blanket cylinders 3.
  • a rubber squeegee 9, 10 is placed against the respective cylinder surface.
  • Fig. 2 shows an application in a doctor blade printing unit 11 for indirect web rotary printing.
  • Gravure is a collective term for all printing processes with printing elements that are lower than the surface of the mold.
  • the intaglio printing unit 11 comprises an intaglio printing cylinder 12 with a doctor blade 13 for doctoring off the ink before printing from all non-image areas, so that the ink only remains in the recessed image areas, as well as a rubber cylinder 14 and an impression cylinder 15, between the latter two the web W passes through.
  • Both the gravure forme cylinder 12 and the rubber cylinder 14 are each assigned an extinguishing device 17, 18, each with a rubber doctor blade 19, 20 following in the direction of rotation of the cylinders 12, 14 of the extinguishing device 17, 18.
  • the gravure form on the cylinder 12 can be erased by washing out the ink and the filler material from the grid network and cleaning the transfer cylinder 14 during the printing operation or during a printing pause.
  • Thermoplastic fillers ie thermoplastics (plastomers), are preferably used as filler material.
  • plastomers thermoplastics
  • polyolefins, vinyl polymers, polyamides, polyesters, polyacetals, polycarbonates, and in some cases also polyurethanes and ionomers can be used for this.
  • FIG. 3 shows an extinguishing device 7, 8 or 17, 18 in detail.
  • a high-pressure extinguishing chamber 30 is placed, in the housing 31 of which a plurality of high-pressure nozzles 32 arranged in series parallel to the cylinder axis are provided and a water supply 33 leads in and out a water drain 35 (FIG. 3a).
  • the water supply 33 leads via a commercial high-pressure cleaning system 34 connected upstream of the extinguishing chamber 30, while the water outlet 35 leads to a pump and suction combination 36 with filter downstream of the extinguishing chamber 30 (FIG. 3b).
  • the still pressure cleaning system 34 includes a compressor 40 and a heating container 50.
  • the extinguishing chamber water outlet 35 leads to the pump and suction combination 36 with a separator 41 for air and a pump with filter system 42 for the water outlet 43. The air can be sucked off by means of the suction motor 44 of a suction cup.
  • the water jet is preferably heated to approximately 85.degree. C. and thus has sufficient energy to also remove the imagewise filling material of the basic cup pattern of a filled gravure blank.
  • the water in the working area of the extinguishing device can also be used together with the so-called Crack air "are sucked off.
