Definitions

  • the invention relates to a washing device for cleaning a cylinder of a printing press according to the preamble of claim 1.
  • washing devices are used for reasons of good print quality.
  • a washing device of a blanket cylinder of an offset printing press which has two closely arranged brush rollers that are in direct contact with the blanket cylinder, the washing liquid being fed through the hollow axes of the rollers and through bores arranged around the circumference of the axes.
  • a plurality of wires, which represent the deflection element, are provided on the mutually opposite lateral surfaces of the brush rollers. Through the wires forming the deflection element, the dirt and washing liquid particles thrown off at the respective contact point with the rubber blanket cylinder are to be thrown towards the respectively adjacent brush roller. This means that corresponding dirt particles get from one brush roller to the other and therefore still have to be removed. Then, the supply of the washing liquid through the axes of the brush roller, in addition to a considerable washing liquid requirement, results in increased construction costs, with regard to appropriate seals, etc.
  • the object of the invention is therefore to design a washing device of the type in question of simple construction in such a way that there is an increased washing effect with low washing liquid consumption.
  • the deflecting element is designed as a distributor tube lying in the range of rotation of the bristles of the brush roller, so that it fulfills a double function: on the one hand, it serves to deflect the bristles, whereby a mechanical cleaning effect is achieved by moving the bristles along the deflecting element and a subsequent resilient return movement of the bristles .
  • the distributor pipe also serves to supply the washing liquid through the outlet openings, which are oriented radially to the brush axis. Since the distributor pipe does not rotate with the brush roller, as in the prior art, the structural measures for sealing can be kept low.
  • the washing liquid emerges directly at the location of the mechanical cleaning of the bristles themselves.
  • the washing liquid After the washing liquid has left the outlet openings, it initially flows in the direction of the brush axis and thereby wets the bristles to which the ink and paper residues removed from the blanket cylinder adhere.
  • the rotating brush roller then reverses the direction of flow of the washing liquid which has reached the bristles by centrifugal force.
  • the bristles must pass through the distributor pipe in their rotating area with deflection. This leads to the fact that the bristles bend due to their internal elasticity and carry out a superimposing wiping movement along the distributor pipe in such a way that any contaminants present on the bristles in Towards the end of the bristles.
  • the distributor pipe is arranged in such a way that the spun off particles of impurities are not directed in the direction of the blanket cylinder, but rather as intended into a collecting trough underneath the washing device.
  • the arrangement of the distributor pipe about 45 ° before the lowest point of the brush axis has proven to be a favorable solution.
  • Feeding the distributor pipe via a storage container arranged above the same leads to an overall technically simple configuration.
  • Corresponding, separately driven feed pumps can accordingly be dispensed with. It is such an arrangement of the container and dimensioning of the outlet openings that a wash liquid jet is formed there, which is directed in the direction of the axis of the brush roller. The cleaning effect accordingly extends over a larger area of the bristles.
  • the arrangement of the brush roller relative to the blanket cylinder is such that the brush roller axis runs below the axis of the blanket cylinder.
  • Above Measure creates a favorable prerequisite for arranging the brush roller - seen in the direction of rotation of the blanket cylinder - a rubber roller rolling off the blanket cylinder in order to accelerate the washing process of the blanket roller.
  • a squeegee roller rolling on the rubber roller then occurs as an accelerator.
  • the latter interacts with a doctor blade for mechanical wiping of contaminants by largely removing the ink and paper particles that come from the rubber roller to the doctor roller.
  • the cleaning effect is enhanced by the measure of bringing the rubber roller arranged above the brush roller into contact with the blanket cylinder, the brush roller and the doctor roller.
  • a closed roller arrangement with optimal cleaning effect is achieved in that the doctor roller is in contact with the brush roller. There is therefore a mutual influence that is aimed at accelerating the removal of existing contaminants and passing them into the sump.
  • the washing device designated as a whole by the number 1 is assigned to a blanket cylinder 2 which is illustrated in sections and can be driven in the direction of the arrow x.
  • a An essential component of the washing device 1 is a rotatably driven brush roller 4 with bristles 3, the axis 5 of which extends below the axis 6 of the blanket cylinder 2.
  • the connecting line 7 passing through both axes 5, 6 closes an angle ⁇ of approximately 20 ° to the horizontal a.
  • a rubber roller 9 rolling on the rubber blanket cylinder 2 or its outer surface 8.
  • the rubber roller 9 illustrated with a full line in FIG. 1 contacts the brush roller 4 in addition to the blanket cylinder 2.
  • a doctor roller 10 rolls on the rubber roller 9. The latter is in turn in contact with the brush roller 4.
  • the diameter of the doctor roller 10 and the rubber roller 9 are smaller than the diameter of the brush roller 4 formed by the bristle tips.
  • the rubber roller axis 11 is arranged above the axis 6 of the blanket cylinder 2.
  • the doctor roller 10 works together with a doctor 12 for mechanical stripping of contaminants.
  • the latter reach the outer surface of the doctor roller 10 via the rubber roller 9 and the brush roller 4 and are then stripped by the doctor blade 12.
  • the latter extends over the entire length of the doctor roller 10, the length of which corresponds to that of the other rollers.
  • the doctor blade 12 is supported by a spring element 13, which is seated on an adjusting device 14.
  • the entire washing device 1 is undertaken by a sump 15 for washing liquid.
  • the latter passes from a storage container 16 under atmospheric pressure via an inlet pipe 17 to a distributor pipe 18 Deflector.
  • the distributor pipe 18 is arranged in the direction of rotation in front of the lowest point 19 of the rotary region covered by the bristles, specifically at an angle alpha of approximately 45 ° in front of the lowest point 19.
  • the distributor pipe 18 is provided with outlet openings 20 directed radially to the brush axis 5.
  • the hole spacing of the outlet openings is approximately 10 mm, so that the brush roller is uniformly wetted through the outlet openings 20.
  • the distributor pipe 18 is fixed by means of a holder 21, so that the distributor pipe 18 remains in its intended position during cleaning.
  • a corresponding liquid level of the storage container 16 above the distributor pipe 18 and coordinated dimensioning of the outlet openings 20 form a wash liquid jet 22 directed in the direction of the axis 5 of the brush roller 4.
  • the rubber roller 9 causes the contaminants, such as ink and paper residues, located on the outer surface 8 of the blanket cylinder 2 to dissolve.
  • the rubber roller 9 can be wetted independently of the brush roller 4.
  • the impurities adhering to the outer surface of the rubber roller 9 partly reach the doctor roller 10 and are removed from there by the doctor 12.
  • the bristles 3 remove corresponding impurities from the outer surface of the rubber roller 9 and partially carry them to the doctor roller 10.
  • the brush roller 4, which is driven counter to the direction of rotation x of the blanket cylinder 2, carries out a traversing movement of 4 to 5 mm.
  • a section of a bristle 3 in its various positions illustrates which movements a bristle 3 executes when it passes through the distributor pipe.
  • the bristle 3 illustrated in full lines in FIG. 2 shows it in the position in which it steps against the circumference of the distributor pipe 18.
  • the entire washing device 1 After cleaning the blanket cylinder 2 or its outer surface 8, the entire washing device 1 is deactivated.
