Definitions

  • the invention relates to a meterable anilox roller, in particular for an anilox inking unit in a rotary printing press, according to the preamble of claim 1.
  • inking units are used in which the printing ink via a doctor blade chamber into the wells or groove-shaped depressions an anilox roller, for example an anilox roller, is introduced, which the Printing ink then usually on the one or more intermediate rollers Surface of a printing form cylinder transfers.
  • an anilox roller for example an anilox roller
  • Anilox rollers with recesses are known, which can be engraved, etched or with the help are introduced into the surface of the roller by lasers, the latter for example consists of steel, chrome, copper and / or ceramic. All rollers have in common that these cells or groove-shaped depressions, the volume of which Manufacture of the roller is set, and after that - apart from that by the Squeegee wear and tear - usually can no longer be changed.
  • the amount of ink transferred to the printing form is determined by the volume of the cells or the groove-shaped depressions of the anilox rollers is determined, and the total The amount of ink required depends on the size of the area to be inked on the printing form it with a view to optimally adapting the amount of ink supplied to the respective Print job desirable to be able to change the amount of color.
  • an object of the present invention to provide an anilox roller especially for an anilox inking unit of a rotary printing press, which has a simple structure, is inexpensive to manufacture and with which an effective and targeted change in the amount of ink transferred from the roller is possible.
  • the meterable anilox roller according to the invention is characterized in that the reason the wells, d. H. the cups or grooves, formed by an elastic material is formed below, from which chambers associated with the depressions are formed to increase or decrease the volume of the wells with a Pressure medium, for example pressurized with compressed air or with a liquid are.
  • a Pressure medium for example pressurized with compressed air or with a liquid are.
  • the anilox roller according to the invention, it comprises a roller base body, in the circumferential surface of which recesses are made, which are designed according to the shape of the wells and via feed channels inside of the roller base body can be acted upon with the pressure medium.
  • a roller base body in the circumferential surface of which recesses are made, which are designed according to the shape of the wells and via feed channels inside of the roller base body can be acted upon with the pressure medium.
  • a flexible coating that for example the shape of a plate or preferably a flexible, on the Has base body slidable sleeve.
  • the Supply channels for the pressure medium to the chambers, or the chambers themselves as one spiral-shaped single groove or if desired as a variety of in Grooves extending in the axial direction over the circumferential surface of the roller base body be trained. Because the grooves are very simple and with a very high accuracy by milling, etching or with the help of a laser in the preferably ground and Let the smooth circumferential surface of the roller base be brought in, is the manufacture of the roller body only slightly more expensive than the production of a conventional anilox roller with a fixed cell volume.
  • the roller body consists of Area of its outer peripheral surface made of porous material, which is connected to the feed channels stands for the print medium, and in which the recesses directly are introduced.
  • the feed channels can, for example, also directly in the porous material.
  • the porous one Material also be shaped as a jacket body, which on a rotatably mounted core of the Roll body is slidable in the axial direction.
  • the feed channels preferably as a in the peripheral surface of the rotatably mounted core of the Roll body introduced and through the inner peripheral surface of the casing body designed groove covered to the outside, which means that the manufacturing effort again can be further reduced.
  • the flexible coating is preferred in the previously described embodiments formed by a sleeve which can be axially slid onto the roller base.
  • the sleeve is advantageously expanded by supplying compressed air the supply channels into the wells of the wells, causing the sleeve in its Diameter is expanded and on an air cushion on the roller base can be postponed. After switching off the compressed air and applying a vacuum via the Feed channels become the flexible coating on the roll base during operation of the Reliably fixed to the roller by applying compressed air to it again Feed channels in reverse when wear and tear occurs can be removed easily.
  • the depressions in the flexible coating as one fixed predetermined structure are introduced, which results in the advantage that the basic cell depth and cell volume in different areas the anilox roller even when applying a uniform vacuum to all cells can have different values, and an adaptation of the anilox roller different print jobs in an advantageous manner by simply exchanging the flexible coating can take place.
  • the pressure medium can be, for example, a gas, preferably air, with a appropriate increase or decrease in air pressure the desired Volume change is brought about.
  • a gas preferably air
  • Pressure medium it is also possible as Pressure medium to choose a liquid, which gives the advantage that due to the incompressibility of liquids and the comparatively low temperature-related volume change of the same a very constant cell or Groove volume results, which is also at a high contact pressure of the rollers other rollers or only slightly changed in the event of strong temperature fluctuations.
  • the use of liquids significantly generate larger pressures, which change the volume of the wells can be used.
  • the structured tube 2b can, for example, be mounted on a rotatable one Roll core 2a may be axially slidable.
  • the reason 8 of the wells will be thereby formed by a thin wall, below the one with a pressure medium actable chamber 10 is arranged, which by between the depressions 6th webs 12 arranged below the same is limited.
  • the roller base body 2 consists of solid material, for example made of aluminum or steel, in which preferably axial and radial Feed channels 14a and 14r are introduced.
  • the radial feed channels 14r open into one Pressure distribution chamber 16, which is in the circumferential surface of the roller main body 2 recesses 18 is in flow connection.
  • the recesses 18 can be formed, for example, as a spiral-shaped groove, or can have the shape of a cup.
  • the cells can continue z. B. in itself extending axially through the roller base body 2, in FIG. 2 not supply bores shown may be connected to the pressure distribution chamber 16.
  • a Cover 20 made of a flexible material, such as rubber, plastic or applied a thin-walled metal.
  • the cover 20 is preferably as a sleeve formed, which by applying compressed air to the supply bore 14a on a Air cushion can be pushed axially onto the roller body 2, and there after Switching off the compressed air and / or keeping it in a secure position when applying a vacuum becomes.
  • the sleeve has a predetermined structure, whereby the basic volume of the depressions 6 as a whole and in different Adjust areas of the peripheral surface of the roller 1 to the respective requirements leaves. For example, in non-printing areas, e.g. H. in areas where no ink is to be transferred from the anilox roller 1, a structure with the Wells 6 convex bulges are used, which after Applying a negative pressure to the feed bore 14a or the recesses 18 an essentially flat area is deformed.
  • the recesses 18 in a jacket body 22 made of solid and porous Material are formed, which via radial feed bores 24 with the pressure medium is applied.
  • the radial feed bores 24 can be, for example, with a cavity 26 formed in the interior of the roller base body 2 stand, which acts on the axial supply bore 14a with the pressure medium becomes.
  • the jacket body 22 made of porous material is preferably on a cylindrical smooth-walled core 28 of the cylinder body 2 axially pushed on, which is rotatably mounted in the inking unit of the printing press.
  • the anilox roller 1 according to the invention is not within one shown completed and pressurized housing of the inking unit is housed.
