Definitions

  • the invention relates to a washing device according to the preamble of patent claim 1.
  • the invention has for its object to provide a flawless and largely maintenance-free washing device for inking units in printing presses, which have the harmful side effects with high cleanability which avoids squeegee blades.
  • the advantages achieved by the invention are, in particular, that even the last ink residues are completely removed from the ink roller to be cleaned, since doctoring is avoided.
  • the use of rotating parts avoids the harmful effects of the squeegee blade when the device runs dry, such as scoring.
  • the washing facility is as far as possible maintenance-free, since no squeegee blades can be freed from adhering paint residues.
  • the device can be attached universally to various driven friction rollers 3, as shown by these friction rollers 3 in FIG. 1.
  • the direction of rotation of the friction roller does not have to be taken into account, since the driven rubber roller of the washing device is reversibly driven in the direction of rotation.
  • an inking unit of a printing press which has a plate cylinder 1, on which four application rollers 2 rest.
  • a distribution cylinder 3 is connected to two application rollers 2.
  • the two distribution cylinders 3 are connected to a third distribution cylinder 3 via two intermediate rollers 4.
  • Two further intermediate rollers 4 are connected to a naked cylinder 6, which in turn is connected to a ductor 8 via an ink lifter 7.
  • a dampening unit 9 is connected to an outer application roller 2.
  • the washing device according to the invention which is designated as a whole by 11, is in contact.
  • the cylinders, rollers and other devices shown in Fig. 1 are attached according to their function in bearings or holders of a machine frame, not shown.
  • the enlarged view of the washing device 11 according to the invention is shown in the rest position.
  • a housing 12 with an approximately U-shaped cross section and a lateral opening
  • two rollers are accommodated, a polygon roller 13 and a rubber roller 14.
  • Both rollers 13; 14 are mounted with their stub axles in the housing 12 and arranged side by side so that the outer surface of the polygon roller 13 penetrates into the outer surface of the rubber roller 14 in the contact area A.
  • the rubber roller 14 has a rubber coating with a hardness of max. 15 ° shore.
  • the polygon roller 13 is provided on its surface with a plastic coating. According to the representation according to FIG.
  • the polygon roller 13 has a plurality of distributed surfaces B on its circumference, which seen in the axial direction have a swirl, which improves the smooth running of both rollers 13; 14 results.
  • the rubber roller 14 is driven in a speed-adjustable manner in the arrow direction C by a motor, not shown.
  • the polygon roller 13 is driven by a drive, not shown, for example a toothed belt at the same speed, but in the opposite direction according to arrow direction D.
  • the drive can be designed so that the speed and thus the peripheral speed of the Polygon roller 13 is smaller or greater than the peripheral speed of the rubber roller 14.
  • the surface of the polygon roller 13 is in the tangential direction by means of nozzle bars 16; 17 arranged flat spray nozzles sprayable.
  • the jet direction of the flat jet nozzles runs in opposite directions.
  • the nozzle strips 16; 17 are fed by a cleaning agent supply 18.
  • a filter, a reservoir and a pump is switched on via lines not shown.
  • a bulkhead 21 Arranged in the interior of the housing 12 at the level of the axis of the polygon roller 13 is a bulkhead 21 which is roof-shaped in cross section, the ridge 22 of which extends at the level of the axes of both rollers 13; 14 is located. This results in a reduction in the distance E between the ridge 22 and the surface of the polygon roller 13.
  • the housing 12 is in the arrow direction F on guides 23; 24 displaceable, for example, by the piston 26 of a working cylinder, so that the washing device 11 comes into operative connection with the distribution cylinder 3 in the operating state.
  • Fig. 3 shows the detail X of FIG. 2 in an enlarged view.
  • the driven distribution cylinder 3 according to FIG. 2 rotates in the direction of the arrow G, that is, in the opposite direction to the direction of rotation C of the rubber roller 14, and with its surfaces B it transports cleaning agents 28 from the Nozzle strips 17; 16 in the area H of the polygon roller 13.
  • the surfaces and edges of the polygon roller 13 penetrate into the surface of the rubber roller 14.
  • the ink layer 27 transferred from the distribution cylinder 3 and adhering to the rubber roller 14 is pushed into the contact area A against the edges of the polygon roller 13 as a result of the rubber roller 14 rotating in the direction of arrow C.
  • the ink layer 27 is mixed with the cleaning agent 28 supplied by the polygon roller 13.
  • This mixture 27; 28 ' is from the surface of the polygon roller 13 through the nozzle strips 17; 16 sprayed and passes through the detergent discharge 19 for filtration and the nozzle strips 16; 17 fed.
  • a storage container is also interposed, which, like the pump and the filtration, is also not shown.
  • Cleaning agent 28 is immediately removed again on the cleaned rubber roller 14 in the direction of arrow C as cleaning agent 28 ′′.
  • FIG. 4 shows a further embodiment variant according to FIG. 2.
  • a trough 29 filled with cleaning agent 28, which is connected at its bottom to a vibration generator 31 and into which the surface of the polygon roller 13 is immersed.
  • the vibration generator 31 rests on vibration isolators 32 which are connected to the bottom of the housing 12.
  • the vibration generator 31 works in the ultrasound range and removes any color residues still remaining on the polygon roller 13.
  • the tub 29 fills itself with cleaning agent 28 and paint residues 27, which are applied via the nozzle strips 16; 17 or supplied via the polygon roller 13. The liquid in the tub 29 then overflows automatically and is returned to the cleaning circuit via the detergent discharge 19.
