Definitions

  • the invention relates to a dampening system and a method for the optional application of Fountain solution or cleaning liquid according to the preamble of claims 1 or 3.
  • DE 36 38 607 A1 describes an inking unit in which a collecting container is optionally available different receptacles can be connected.
  • the invention has for its object a dampening system and method for optional Applying dampening solution or cleaning liquid.
  • a dampening unit 01 for a printing unit of a rotary printing press exists u. a. out a frame 02, which is an axially parallel to a roller, for.
  • B. one Transfer roller 03 for dampening solution housing 04 carries.
  • the Transfer roller 03 protrudes with one part of its lateral surface 06 into the one side Housing 04 opened towards transfer roller 03.
  • Housing 04 takes several Means spaced apart in the axial direction of the transfer roller 03 for Applying dampening solution, e.g. B. spray nozzles 07.
  • the spray nozzles 07 are on a crossbar 08 fastened between the frame parts arranged on a nozzle carrier 10 and each point with their spray opening in Direction of the outer surface 06 of the transfer roller 03.
  • Each of the spray nozzles 07 is on a common feed line 11 provided with a check valve 09 connected, which in turn via a multi-way valve 12 optionally with a feed line 13 for dampening solution or a feed line 14 for cleaning liquid can be connected.
  • the housing 04 receiving the spray nozzles 07 is on its underside as Collection container 16 formed so that one or more liquid return points 17th arise, each opening into a manifold 18.
  • the manifold 18 is over a multi-way valve 19 optionally via lines 21; 22 with a collecting container 23; 24 connected for dampening solution or for cleaning liquid.
  • the dampening unit 01 can have two in addition to the transfer roller 03 or three other cylinders or rollers, one of which is not shown Moist application roller with a form cylinder and this in turn with a Rubber cylinder of a printing unit interacts.
  • a rinsing process takes place. During the rinsing process is already for Apply suitable dampening solution by means of the dampening system, but not in the Collection container 23 for dampening solution (which is used for reprocessing) passed, but in the collecting container 24 for cleaning liquid.
  • the spray nozzles 07 are thus during the rinsing with the supply line 13 for dampening solution and the collecting container 16 is with the collecting container 24 for cleaning liquid connected.
