Definitions
- the invention relates to an applicator for printing machines for applying liquid media to a printing material.
- liquid media / for example lacquers or metal printing inks / are applied in printing machines via an applicator and a lacquer form cylinder which is operatively connected to the applicator to the printing material guided by the printing cylinder.
- the liquid media are applied via applicators with an applicator roller and a feed system.
- a feed roller is used as the feed system / which forms a squeeze roller system with the application roller (DE 342 78 98) and on the other hand an immersion roller rotating in a trough is used / which interacts with an application roller (DE 332 40 96).
- a feed system is also used / in which a dosing roller is assigned to the dipping roller interacting with the application roller (DE 384 15 71).
- the liquid media are also applied via applicators with a rastered applicator roller and a feed system designed as a doctor blade (EP 0071 180).
- Devices for applying different media are known / in which two interchangeable metering systems are assigned to the forme cylinder / such that two interchangeable rollers with the same outside diameter and different surface hardness are assigned to the coating forme cylinder as the applicator roller and metering roller (squeeze roller principle) are or a chamber squeegee and a rastered application roller are assigned to the forme cylinder (DE 433 48 03).
- a disadvantage of this device is the high changeover effort - exchange rastered application roller for smooth application roller - when changing the medium to be applied.
- the object of the invention is to create a commissioned work / with which different media can be processed.
- Fig. 1 applicator with chamber doctor and plunger roller feed system
- Fig. 2 applicator with chamber doctor and squeeze roller feed system.
- Applicator units 2 with feed systems of three basic types are used for applying liquid media to a forme cylinder 1 of a printing press.
- FIG. 1 shows an applicator unit 2 of a printing press which is operatively connected to the forme cylinder 1 and is designed with an applicator roller 3 / a chamber doctor blade 6 which is operatively connected to the applicator roller 3 and a feed system 10 which forms a first basic type a trough 4 which contains the medium to be applied and which is in circulation / is in operative connection with the application roller 3.
- a feed system 10 described is expanded by a metering roller 7 (dashed line in FIG. 1), it represents a second basic type of feed system 10.
- the applicator unit consists of the applicator roller 3, the chamber doctor blade 6 and a squeeze roller system 8 assigned to the applicator roller 3. is found in the wedge-shaped space 9 formed by the squeeze rollers 8.
- the feed system 10 and the chamber doctor blade 6 are each connected to a known / not shown attachment and detachment device (indicated by two-way arrows in the figures) and thus can be optionally assigned to the applicator roller . By selective assignment is meant
- application roller 3 and dipping roller 5 In synchronous operation, application roller 3 and dipping roller 5 have the same direction of rotation with respect to the point of contact and in reverse operation application roller 3 and dipping roller 5 have different directions of rotation with respect to the point of contact.
- the application roller 3 is designed as a rastered application roller 3 and the chamber doctor blade 6 / the feed system 10 and the rastered application roller remain arranged in the machine even when processing different media.
- the application roller and / or the feed system no longer need to be converted; for the system changeover, it is sufficient to switch the chamber doctor blade 6 and / or the feed system 10 on and off without exchanging the application roller.
- the application roller 3 is equipped with a wear-resistant hard surface / preferably ceramic-coated.
- the grid can be used: perforated grid, spaced grid / line grid / grain grid / contact grid / cross grid grid, brick grid etc.
- the liquid medium is transported via the wells / lines of the rasterized application roller; the dipping roller or the squeezing roller remove the excess medium.
