Definitions

  • the invention relates to a method for cleaning cylinders and rollers of a printing unit of a printing press, in particular an offset printing press.
  • a method for cleaning cylinders and rollers is known from EP 0 453 853 A2. According to the method, the relative positions of the blanket cylinder, plate cylinder and associated rollers are freely controllable, so that a spacing or contact position can be assumed during the cleaning process.
  • DE 36 06 006 A1 discloses a cleaning device for the inking roller of an offset printing unit, which has a primary and a secondary strand for the cleaning fluid supply.
  • a variable amount of cleaning fluid depending on the ink layer thickness and the number of rollers / cylinders, is fed to the inking roller train.
  • the cleaning liquid is then removed from the single drum with the paint remnants removed by a squeegee.
  • the object of the invention is therefore to develop a method that noticeably reduces the cleaning time and the cleaning fluid consumption with the same washing quality.
  • the task the invention is solved by the characterizing part of the main claim. Further training results from the subclaims.
  • the circumferential length of the roller train increases.
  • the number and / or the cleaning time of the washing sequences increases manually or in a controlled manner.
  • the printing unit consists of an ink fountain 7 with ink fountain roller 6, an ink lifter 5 and a series of ink rollers, which are referred to as an ink roller train 4.
  • a detergent spray device 10 and a water spray device 11 are assigned to the inking roller 4.
  • the inking roller 4 is assigned to a plate cylinder 1 which carries a printing plate.
  • the plate cylinder 1 is also assigned a dampening roller train 3 which can be coupled to the inking roller train 4 via a bridge roller.
  • a blanket cylinder 2 of an offset printing unit is assigned to the plate cylinder 1. Further components of the printing unit will not be discussed further.
  • a doctor device 8 is arranged on one of the last rollers of the inking roller train 4.
  • the doctor device 8 is received in a swivel joint and can be pivoted by means of an actuating device 9.
  • the actuating device 9 and the detergent spray device 10 and the water spray device 11 are connected to a control system in terms of circuitry.
  • the mode of operation is as follows: The washing sequence is activated via the control.
  • the detergent spraying device 10 sprays the detergent onto the adjacent inking roller train 4 for a defined time.
  • the detergent is then distributed over the inking roller roller 4 until approximately the same layer thicknesses of dyeing agent and detergent are present.
  • the doctor device 8 is periodically placed on one of the last rollers of the inking roller 4 and doctored off the emulsion of ink and detergent.
  • the inking roller 4 is parked by the plate cylinder 1.
  • ink fountain 7, ink fountain roller 6 and ink lifter 5 are shown in FIGS Ink roller 4 integrated. If the ink fountain 7 needs to be emptied (filling / changing the color), all paint slides are closed and the ink fountain is swung out after emptying.
  • a very thin ink film is then still on the ink fountain roller 6.
  • the ink lifter 5 is released, the stripe width of the ink lifter 5 is set to maximum, and thus the ink fountain roller 6 is also cleaned by coupling ink lifter 5 with the remaining ink roller train 4.
  • the washing sequence also applies analogously to the use of water as a cleaning fluid.
  • a vegetable oil ester is preferably used as the cleaning fluid.
  • the washing sequence can be repeated several times.
  • the plate cylinder 1 is brought into contact with the inking roller 4 via the control, and thus the printing plate on the plate cylinder 1 is also cleaned.
  • the dampening roller train 3 is also to be cleaned, it is coupled to the inking roller train 4 via a bridge roller.
  • the dampening roller of the dampening roller train 3 can also be placed on the plate cylinder 1.
  • at least one washing sequence with water as a detergent is finally carried out.
  • inking rollers 4 and plate cylinder 1 with a corresponding plate or from all rollers (inking roller train 4, dampening roller train 3) and plate cylinder 1 with a plate longer spraying, pause and doctoring times are necessary to achieve the necessary quality.
  • the cleaning times are preferably extended by an editable factor.
  • the inking roller train 4 and the dampening roller train 3 are turned off by the plate cylinder 1.
