Definitions
- the invention relates to a dampening unit and a method for the optional application of dampening solution or cleaning liquid according to the preamble of claims 1 or 3.
- a spray dampening unit has become known from an advertising leaflet "Spray damps and rubber cleaning in one" from the Swedish company Grafiskt Team AB, S-57 121 Nässjö, by means of which plate cylinders or rubber cylinders of a printing unit can alternatively be cleaned.
- DE 36 38 607 A1 describes an inking unit in which a collecting container can optionally be connected to different collecting containers.
- the invention has for its object to provide a dampening system and method for optionally applying dampening solution or cleaning liquid.
- the advantages which can be achieved with the invention consist in particular in that the different liquids which can optionally be applied to the dampening solution roller, when not in use, each separately, ie. H. can be fed to different collection containers according to type. Subsequently, the liquids can either be reprocessed, added to the respective liquid supply, or disposed of.
- Figure 1 is a schematic representation of a cross section through a spray dampening unit.
- Fig. 2 shows a longitudinal section II - II of FIG. 1 showing the left end of the spray dampening unit, but with switching means.
- a dampening unit 01 for a printing unit of a rotary printing press exists u. a. from a frame 02, which is an axially parallel to a roller, for. B. carries a transfer roller 03 for dampening solution extending housing 04.
- the transfer roller 03 protrudes with a part of its lateral surface 06 into the housing 04 opened on one side in the direction of the transfer roller 03.
- the housing 04 takes several means for applying dampening solution, eg. B. spray nozzles 07.
- the spray nozzles 07 are arranged on a crossbar 08 fastened between the frame parts on a nozzle carrier 10 and each point with their spray opening in the direction of the lateral surface 06 of the transfer roller 03.
- Each of the spray nozzles 07 is connected to a common feed line 11 provided with a check valve 09, which in turn can be connected via a multi-way valve 12 optionally to a supply line 13 for dampening solution or a supply line 14 for cleaning liquid.
- the housing 04 receiving the spray nozzles 07 is designed on its underside as a collecting container 16, so that one or more liquid return points 17 are formed, each of which opens into a collecting line 18.
- the manifold 18 is via 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 or three other cylinders or rollers, of which a dampening roller (not shown) interacts with a forme cylinder and this in turn interacts with a blanket cylinder of a printing unit.
- a dampening roller (not shown) interacts with a forme cylinder and this in turn interacts with a blanket cylinder of a printing unit.
- the function is as follows:
- the excess dampening solution running off the transfer roller 03 is received in the collecting container 23 for dampening solution. If the transfer roller 03 is sprayed with cleaning liquid, then both multi-way valves 12; 19 z. B. switched electrically operable and the unnecessary cleaning liquid is received in the collecting container 24 for cleaning liquid.
- dampening solution suitable for printing is already applied by means of the dampening unit, but is not passed into the collecting container 23 for dampening solution (which serves for reprocessing), but rather into the collecting container 24 for cleaning liquid.
- the spray nozzles 07 are thus connected to the supply line 13 for dampening solution during the rinsing and the collecting container 16 is connected to the collecting container 24 for cleaning liquid.
