Definitions

  • the invention relates to a machine for the Sheet rotary printing or sheet coating with the features the preamble of claim 1.
  • Corona treatment is an electrical one Flame with high voltage.
  • the ionized air between the Electrodes grip the surface of the plastic through ozone and oxygen on, also an oxidation.
  • On the Plastic surface polar groups are generated that are good are wettable.
  • the corona pretreatment is one of the most most of the processes used in surface finishing become. With it the surface tension of polymers Films and foils, aluminum foils, laminated paper and cardboard as well as sandwich materials before they are printed, be glued or coated. With this treatment the Adhesion between the surface to be bonded Improved layers or better adhesion of the Brush or paint achieved.
  • the end effect of the treatment depends on various parameters, such as the performance of the Electrodes, the duration of the discharge, the type of treated Material, temperature and humidity, any Impurities, the surface morphology and especially the gap width as small as possible.
  • Electrode segments have to adjust their settings despite vibration the system and other unfavorable conditions.
  • JP 591 31 460 A is a device for arcuate Substrates known, however, by an all-over Corona treatment, no accurate registration required and accordingly no gripper technology for the Sheet transport is available.
  • the sheets are on tapes in the flat condition with vacuum, without gripper, transported. The Accordingly, the gap width is easy to set and stable to handle.
  • the corona treatment of sheet materials in the Printing industry is an established technology (DE 199 10 740, DE 198 43 955, DE 101 06 385).
  • the gap width of a few Is composed of the thickness of the millimeters Substrate web and a gas gap above the to be treated Substrate surface.
  • the registers are accurate Transport gripper elements needed, but with their Gripper back is forced to millimeter above the Are arranged substrate surface and thereby the Gap width too large over the substrate surface to be treated for optimal corona treatment.
  • DE 100 39 represents the state of the art and the main reference point 073 there, although an optimal one despite the use of grippers Gap width is achieved by a lifting device or Gripper recesses are provided.
  • a Drum with gripper recess is format-related and therefore relatively large and complex due to extra insulation.
  • the Printing cylinder moves constantly at printing speed.
  • the feed system now has the task of guiding the sheet exactly, to bring it to the printing speed and to the grippers of the printing cylinder.
  • this task is with orbital grippers solved, which are arranged above or below the arch.
  • the substrate can be primed with a primer be coated, but that requires an extra printing unit and Dryers required for this in the printing press, see DE 100 04 997 A1. Printing machines with such a level of equipment are correspondingly expensive.
  • the invention is based on the object of a novel Sheet feed system with adequate space develop to the bow, precisely guided to the Bring production speed and to the grippers of the Pass printing cylinder, the front and / or also the back of the sheets with a surface treatment, e.g. Corona treatment and without additionally upstream drums, transfer cylinders or Printing units.
  • a surface treatment e.g. Corona treatment and without additionally upstream drums, transfer cylinders or Printing units.
  • the invention solves this problem by means of a sheet feed system with the characterizing features of claim 1. With regard to other essential design features referred to the subclaims.
  • FIG. 1 The side view of the system shown in Fig. 1 shows a traditional high pile feeder 1 for a sheet processing machine 3 with gripper technology 5.
  • the system 2 has the task to lead the bow exactly on the Bring production speed and to the gripper 5 of the Transfer impression cylinder 11.
  • the exact alignment is done e.g. B. in a stop moment in approximately at 9, the arc in the circumferential direction z. B. via a Conveyor mark (not shown) and laterally z. B. via a Page mark 8 is aligned before z. B. with the Preferred rollers 7 is accelerated.
  • Appendix 2 is a surface treatment system 6 integrated in such a way that the arch from above and / or can be treated from below, e.g. with a Corona treatment.
  • Fig. 2 shows a side view in the direction of Y Side mark 8, the preferred rollers 7, the stopping moment 9, the two chambers of the surface treatment system 6, the Access for regulated suction and / or blown air 14, electrodes 12 and opposite poles 13. This system is in one Stand arranged.
  • FIG 3 shows a side view of the plant unit from FIG 2, which, however, can be adjusted with e.g. 10 mm after is offset below. This creates a when entering the sheet Curvature 16 of the flexible substrate, which is advantageous affects the accuracy of the register.
  • the system is complete with your surface finishing system 6, e.g. a corona treatment system, feed rollers and Bow alignment mechanisms adjustable in height by X to, each according to paper thickness, an alternative for the substrate to create the moment when the bow to the stop is guided within the gripper 5. Stronger substrates like Cartons are introduced almost horizontally. With flexible Substrates with curvature, the system 2 is down adjusted.
  • your surface finishing system 6 e.g. a corona treatment system, feed rollers and Bow alignment mechanisms adjustable in height by X to, each according to paper thickness, an alternative for the substrate to create the moment when the bow to the stop is guided within the gripper 5. Stronger substrates like Cartons are introduced almost horizontally. With flexible Substrates with curvature, the system 2 is down adjusted.
  • the gripper bar 5 is adjustable to a circumferential and To enable diagonal registers.
  • a of the chambers are supplied with suction air around the substrate easy to brake.
  • FIG. 4 is a side view of a high performance feeder shown, the substrate sheet after separation over Slider 21 via a vacuum belt 17 and supported by Guide rods 20 are guided on the grippers. To Separation from the stack 4, the sheets are over a Vacuum belt system 22 out.
  • the vacuum belts are of the type arranged sunk that into an upper chamber, e.g. Electrodes 12 and into a lower chamber, e.g. Opposite poles 13 can be integrated to a surface treatment, such as e.g. to enable a corona treatment.
  • the upper processing cylinder 10 is part of the Sheet-fed rotary printing or coating machine 3 where this System 2 and the feeder 1 of the machine 3 are connected upstream.
