Definitions

the invention relates to a device for dosing liquid media in offset printing machines.
coating units are used to apply liquid media, such as varnish, to printing sheets to be finished.
These coating units are known and can be divided into the following main groups - scoop roller coating units (DD 278 551 A1), squeeze roller coating units (Gbm G 930 5552 U1), doctor blade coating units (DD 27 855 A1), chambered doctor blade coating units (Gbm G 910 5552 U1). It is also known to optionally assign a scoop roller coating unit (DE 43 44 084 C1) or a squeeze roller coating unit (DE 43 34 803 C1) and a chamber doctor coating unit to a forme cylinder of a printing press.
the scoop roller coating unit consists of an application roller assigned to a forme cylinder and an upstream scoop roller which rotates in a paint reservoir.
the scoop roller is assigned a metering roller in some versions.
the paint is metered either by a speed difference between the scoop roller and applicator roller or by the metering roller.
the object of the invention is to provide a device for dosing liquid media for a wide range of applications.
a forme cylinder 1 of a printing press which works together with an impression cylinder (not shown), can optionally be assigned a chambered doctor blade applicator 2 and / or a combination applicator 3.
the combination applicator 3 receives an applicator roller 4 assigned to the forme cylinder 1 of the printing press.
This applicator roller 4 is operatively connected to a scoop roller 5, forming a gap 6. Under gap 6, the width of the rollers 4; 5 extending wedge-shaped space understood above the touching rollers.
the scoop roller 5 rotates in a media reservoir 7 and the gap 6 is a media feed 8 assigned.
the scoop roller 5 is operatively connected to a metering roller 9.
Scraper blades 10 are arranged laterally on the end faces of applicator roller 4 and scoop roller 5.
the scraper blades 10 arranged on both sides are equipped with an outlet opening through which an outflow of the stripped medium to the media reservoir is made possible.
the chambered doctor blade applicator 2 which either optionally or in addition to the combination applicator 3 is used, consists of the actual chamber doctor blade 11 and the applicator roller 4, the applicator roller 4 being designed as a rastered applicator roller.
the operation of the device according to the invention is described below.
the optional use of the chambered doctor blade applicator unit 2 or of the combination applicator unit 3 presupposes that either when using the combination applicator unit and the chambered doctor blade applicator unit, an application roller 4, designed as a screened application roller, is used, or an application roller used when using a combination doctor unit is used by a screened unit Applicator roller is replaced.
the scoop roller 5 rotating in the media reservoir in conjunction with the metering roller 9 pre-doses the medium; in addition, the medium is introduced into the gap between the scoop roller 5 and application roller 4 via the media feed 8 and metered by means of these rollers. The excess medium is through the rollers 4; 5 assigned doctor blade 10 removed.
the combination applicator can also be used as a squeeze roller mill - Applicator roller, scoop roller, media feed, scoop roller does not run in the media reservoir - or as a roller applicator - scoop roller, applicator roller, media reservoir, without Media supply, with or without metering roller - operated.
