Definitions

  • the present invention relates to a flexographic printing apparatus for application to offset printing units.
  • offset printing units or assemblies carry out an indirect type of printing and they are not designed for easily carrying out other types of printing processes such as the flexographic printing, which is typically a direct type of printing.
  • the aim of the present invention is to overcome the above mentioned drawbacks, by providing a flexographic printing apparatus designed for application to offset printing units, for quickly and simply transforming a conventional offset printing unit into a flexographic printing machine, with the possibility of easily selecting the type and amount of inks to be applied.
  • a main object of the present invention is to provide such a flexographic printing apparatus allowing to automatically replace the anilox cylinders or rollers engaging with the printing plate, thereby providing a printing machine very flexible from the operating standpoint.
  • Another object of the present invention is to provide such a flexographic printing apparatus which, owing to its specifically designed construction, is very reliable and safe in operation.
  • Yet another object of the present invention is to provide such a flexographic printing apparatus, for application to offset printing units, which can be easily made starting from easily available elements and materials and which, moreover, is very competitive from a mere economic standpoint.
  • a flexographic printing apparatus for application to offset printing units, characterized in that said apparatus comprises, at a printing plate bearing cylinder of an offset printing machine, a supporting unit for supporting a plurality of anilox cylinders, which can be caused to selectively contact said printing plate bearing cylinder.
  • an offset printing unit generally indicated by the reference number 1 is herein illustrated; said offset printing unit comprises, in a per se known manner, a sheet feeding assembly 2, provided for conveying the sheet to be printed upon to a transfer roller 3, which is coupled to a printing cylinder 4, in turn operatively associated with an output sheet transfer cylinder 5; on this cylinder 5 a chain 6 is entrained, said chain including a plurality of grippers for conveying the sheet inside a drying assembly or unit, generally indicated by the reference number 7.
  • the main feature of the invention is that, at said printing plate bearing cylinder 9 of the offset printing unit, a flexographic printing apparatus generally indicated by the reference number 10 is provided.
  • Said apparatus 10 comprises, substantially, a carousel element 11, including two end flanges 12, which peripherally support the end portions of a plurality of anilox cylinders 13 which, in the embodiment being disclosed are four, but which could be pbviously provided in any desired number.
  • the anilox cylinders have a cylinder surface which has been preliminarily subjected to any desired surface treatments, to provide therein small cells or hollows, in which the printing ink will deposit.
  • the anilox cylinders 13 are engaged, at their end portions, by a slide 20 designed for bringing each individual anilox cylinder 13 to the printing plate bearing cylinder 9.
  • the anilox cylinder 13 contacting said printing plate bearing cylinder 9 is supported, at the end portions thereof, by truncated cone-shaped plug-in elements 21, clearly shown in Figure 4, which can be so driven as to engage with and disengage from a respective anilox cylinder, while providing a perfect centering and locating of said cylinder.
  • an ink application unit 30 operates, said ink application unit being provided, at its contact end portions, with doctor blades for properly spreading the desired inks on the anilox cylinder, which inks could be water-based inks, U.V. based inks, as well as "flexo-inks" such as of a gold type.
  • said inks will have a comparatively high fluidity, and will include therein very volatile solvents so as to facilitate the drying of said inks.
  • the anilox cylinder will be rotatively driven by a driving geared unit 35, thereby spreading the ink over the printing plate to directly print the sheet.
  • holding arms indicated by the reference number 40, provided for engaging the end portions of the anilox cylinders or rollers in order to properly hold said cylinders on their supports, while allowing said cylinders to be easily brought to their operating positions.
  • operating units can also be mounted on the disclosed flexographic apparatus, such as embossing units, recording-embossing units as well as numbering, punching units and so on.
  • scrapable inks could be also used, on paper sheets having a basic weight from 60 to 80 grams and with a maximum thickness of 12/10 mm.
  • the used materials provided that they are compatible to the intended application, as well as the contingent size and shapes, can be any, depending on requirements.
