Definitions
- the invention relates to a dampening system according to the preamble of claim 1.
- EP 07 19 639 A2 shows a dampening unit with four rollers.
- EP 04 62 490 A1 discloses a four-roller dampening unit in which a dampening roller and a distributor roller have the same speed.
- the object of the invention is to create a dampening system that meets high printing quality requirements.
- a two-roller dampening system can be retrofitted, ie. H. expandable, is trained.
- a two-roller dampening system can be retrofitted, ie. H. expandable, is trained.
- a sufficient for a 1/1 pressure two-roller dampening system if necessary, for. B. for a four-color newspaper printing, to be upgraded to a three-roller dampening unit with higher moisture quality.
- Figure 1 shows the cross section through a two-roller dampening system in a schematic representation.
- Figure 2 shows the cross section through a three-roller dampening system in a schematic representation.
- Fig. 3 shows the cross section through a four-roller dampening system in a schematic representation.
- a dampening unit 01 for a printing unit of a rotary printing press consists of a friction roller 04 rotatably mounted in a side frame 03 with a shaft journal 02.
- the friction roller 04 has a hard outer surface, e.g. B. made of chrome. It can be driven by means of a drive (not shown) and can be moved back and forth in the axial direction with a certain stroke.
- a plate cylinder 06 is arranged on the friction roller 04 and on the plate cylinder 06 adjustable, rubber-coated application roller 07.
- the application roller 07 is by means of actuating and holding elements 08, for. B. swivel levers 09, with journal supports 11 and working cylinders 12 on the aforementioned devices on and off.
- the friction roller 04 is by means of a known fountain solution source 13, for. B. the spray jets of a spray nozzle 13 having spray bar can be moistened.
- a dampening unit 14 In a dampening unit 14 according to a second embodiment (FIG. 2) one is connected to the Rubbing roller 04 additionally adjustable, rubber-elastic coated transfer roller 16 is provided, which can be switched on and off by means of the actuating and holding elements 08 analog actuating and holding means 17 on the rubbing roller 04.
- a dampening unit 21 compared to the second dampening unit 14 in the side frames 03, additional bores are provided for receiving shaft journals 18 arranged in bearings in an applicator roller 19 with a hard lateral surface arranged at a distance a from the friction roller 04, similar to that of FIG Shell surface of the friction roller 04.
- the applicator roller 19 works without an axial stroke and is z. B. is moved by the friction of the transfer roller 16 which can be swung out to the friction roller 04 and to the applicator roller 19 and which operates here as an intermediate roller.
- the application roller 19 and the friction roller 04 have approximately the same peripheral speed.
- the side frames 03 of the rotary printing press are equipped with additional bores for receiving the retrofittable transfer roller 16 and applicator roller 19.
- the application roller 19 is driven by the friction roller 04 in a form-fitting manner.
- the drive takes place, for example, by means of a belt drive or gear transmission.
- the fountain solution source 13 now acts on the applicator roller 19.
