Definitions

  • the invention relates to an anilox roller for a flexographic printing machine and a Flexographic printing machine with such anilox roller.
  • anilox rollers serve to print the printing ink from one Take up the doctor blade and roll it onto a roller that runs around the circumference of the anilox roller Transfer cylinder.
  • anilox rollers are usually formed by a metal cylinder having a ceramic layer on its peripheral surface carries a fine grid in the outer surface with the help of a laser Shallow cups were formed when passing through the chamber doctor blade filled with ink and then the ink to the printing cylinder submit.
  • the bearing construction has so far been formed by stub axles, which in are integrally formed at both ends of the metal cylinder.
  • the outside diameter of the printing cylinder is of the desired printing length dependent.
  • the diameter of the anilox roller is not of the desired printing length dependent and is generally smaller than the diameter of the impression cylinder.
  • different jobs are often different Anilox rollers are used, which differ in the nature of the cell grid differentiate. Therefore, the anilox roller of the be replaced more often.
  • Printing cylinders are often designed as hollow cylinders closed at both ends, which are traversed by a continuous axis and hydraulically are clamped on the axis (US-A 3 378 902).
  • European Patent application 99 102 033 a pressure cylinder is proposed, the outer jacket through a sleeve made of a carbon fiber composite material with a coiled scaffold is formed from carbon fibers. This will result in no loss in mechanical strength a weight saving and thus the replacement the pressure cylinder facilitated.
  • the object of the invention is therefore to provide an anilox roller, the given mechanical strength has the lowest possible weight.
  • roller body Anilox roller is releasably clamped on a continuous axis and this Surrounds axis with distance.
  • This two-part construction increases the weight of the anilox roller decreased. Nevertheless, a high mechanical strength is achieved since the axis is stiffened by the roller body, which this axis by a distance surrounds.
  • Another advantage of this solution is that the roller body detached from the axis and by another roller body with a other cells can be replaced. The axis can be in the Printing press remain. To find a suitable selection of cell grids allow, it is therefore sufficient to have an appropriate range of roller bodies to keep in stock, which is then clamped on one and the same axis as required can be. This not only saves costs, but also reduces the weight of the storage racks or storage trolleys used for Storage of the range of roller bodies.
  • the roller body is passed through a sleeve made of carbon fiber material, for example a carbon fiber composite material with a wound structure made of carbon fibers in a matrix made of plastic.
  • the carbon fibers give the roller despite its low weight sufficient strength so that it can surround the axis "self-supporting".
  • the roller body is preferably closed off at both ends by disks, which can also be offset somewhat axially inwards, and those with their inner peripheral edge can be clamped on the axis.
  • the discs can be in be formed in one piece with the roller body, however, can optionally also made separately from the roller body and from a different material and then non-rotatably connected to the roller body.
  • the only drawing figure shows a partially broken side view of a Anilox roller.
  • the anilox roller 10 has a roller body 12 in the form of a tubular Sleeve made of a carbon fiber composite material.
  • a tubular body made of carbon fiber composite material have been used for example as web guide rollers in Printing machines or possibly also as printing cylinders for smaller ones Print lengths used.
  • These tubular bodies typically have a scaffold diagonally wrapped carbon fibers embedded in a plastic matrix are.
  • the roller body 12 is closed off in the region of both ends by disks 14, which are made of metal in the example shown and rotatably with the Roller body are connected.
  • the roller body 12 carries a metallic one on its outer peripheral surface
  • Primer layer 16 made by metallizing the carbon fiber composite material can be formed.
  • a ceramic layer is on the primer layer 16 18 applied, in the outer surface in a known manner a fine Grid from well 20 is formed.
  • the disks 14 are penetrated by a continuous axis 22 made of metal, whose outside diameter is significantly smaller than the inside diameter of the cylindrical roller body 12. Between the axis 22 and the roller body 12 an annular cavity 24 is thus formed. Because of this design and due to the low weight of the roller body 12, the total weight the anilox roller considerably reduced, so that even relatively long anilox rollers easily handled for printing widths of 2000 mm or more can be.
  • the axis 24 forms bearing sections 26, 28 at both ends.
  • the bearing section 26 is stable by two bearings 30 in the machine frame 32 of the flexographic printing machine held while the bearing section 28 by a not shown removable bearing is held. After removing this bearing you can pull the roller body 12 with the disks 14 axially from the axis 22.
  • the axis 22 forms a stop 34 for one of the disks 14, which rotatably with the axle is wedged.
  • the washer 14 is on the removable bearing side releasably clamped on the axis 22 with a clamping bush 36.
