Definitions
- the invention relates to a printing press roller cleaning method and a printing press roller cleaning device according to the claims.
- a cleaning device of this kind is from the DE-A-198 16 660 known .
- Ink rollers of an inking unit in a printing unit for offset printing are moistened by a so-called spray tube for dissolving the paint with liquid, which is sprayed onto one of the rollers and doctored down on another roller.
- One or more of the inking rollers are driven, while other rollers are not driven, but are rotated only by the contact of their roll shell with the roll shell of an adjacent roll.
- the cleaning process must be carried out in a short period of time to shorten the downtime for the printing operation.
- the liquid must therefore be transferred from the roll, which is moistened with the liquid from the spray tube, as quickly and uniformly as possible to all rolls of the compactor. If little liquid is sprayed onto the one roller, it will take a long time for all rollers to be moistened.
- the invention enables the problem to be solved in a simple and inexpensive way to achieve a safe cleaning of all rolls of a compactor in a short time.
- the invention ensures that the liquid is rapidly applied and distributed in a short time to all rollers up to and including the doctored-off roller.
- the invention prevents over-rolling of rolls and thereby slippage or stagnation of non-driven rolls.
- Standing rollers prevent the transfer of fluid to other rollers and thereby cause a liquid accumulation in the roller winding, from which liquid is laterally squeezed out.
- the Rushbefeuchturigszonen ensure sufficient frictional adhesion between the rollers through which all non-driven rollers are rotated by adjacent rollers and no rollers slip due to over-wetting of the adjacent roller. Furthermore, a fast fluid transfer to all rollers is achieved.
- the invention uses substantially fewer discharge ports or nozzles than the prior art.
- Liquid may be solvent, detergent, detergent or solvent-containing water, water with one or more additives which affect the printing process, pure water or any other liquid. Furthermore, the type of liquid can be changed during the washing process. For example, initially detergent or solvent or water containing it may be used to dissolve the paint from the rolls, and then rinsed with clean water.
- Rollers also include press cylinders, but especially inking rollers.
- a roller may be driven by an electric motor, a pneumatic motor or a hydraulic motor, or by a drive connection from another roller or cylinder of the printing press.
- Non-driven roller is a roller which rotates only by being in contact with an adjacent roller and being co-rotated by the frictional resistance.
- Dot-shaped cross-section of the liquid jets means a jet with a small cross-section and distance from each other over the entire jet length from the nozzle to the point of impingement on the roll, in contrast to a spray jet or a very wide flat jet which already on impact with the roll or even before each other touch or mix with each other.
- “Scraper device” for stripping the liquid and possibly detached from it roll contamination This may be a squeegee, a brush or a cloth or other element, with which the liquid and possibly dissolved by her dirt from a roller is removable.
- Fig. 1 shows schematically and not to scale a printing unit comprising a plate cylinder 2, a blanket cylinder 3 contacting him, a printing cylinder 4 contacting them, an inking unit 6 and a dampening unit 8.
- a dampening solution liquid offset printing unit is a dampening solution liquid offset printing unit.
- the invention can also be used for a dry offset printing unit.
- the printing unit can be part of a sheet-fed offset printing press (printing of sheets) or a web offset printing press (printing of sheet-like printing material).
- the invention is also applicable to other types of printing machines (high pressure, gravure printing).
- the printing material 10 (sheet or web) passes through the nip 11 between the blanket cylinder 3 and the pressure roller 4. The image is transferred from the plate cylinder 2 on the blanket cylinder and from there to the substrate 10.
- the inking unit 6 may be of any type, which contains at least one ink roller driven by a motor and at least one non-driven ink roller, which latter is driven by the frictional resistance of its lateral surface with the lateral surface of another roller.
- the inking unit 6 of Fig. 1 includes, as an example, a paint box 14 and a roller train of ink rollers 16-27, of which a roller 16 is a so-called ductor roller for receiving ink from the ink fountain 14 and of which at least one roller is driven by an electric motor or other motor drive and not shown of which one or more rollers have no motor drive, but are driven only by touching their roll shell with an adjacent roll of this adjacent roll, which may also be a roller without motor drive.
- a doctor blade 30 is engageable toeuerrakeln of this roller 27 paint and other contaminants, preferably in a receptacle 32nd
- the dampening unit 8 contains a dampening solution tank 36 from which dampening solution liquid is applied to the peripheral surface of the plate cylinder 2 via a train of dampening rollers 38, 39, 40 and 42 to form ink-repelling areas corresponding to the printed image to be printed.
- a transfer roller 44 or more transfer roller may be provided which on the one hand in circumferential contact with a dampening roller, z. B. dampening roller 42, and on the other hand in circumferential contact with a paint roller, for example, the ink rollers 26 and 27.
- a printing unit roller cleaning device 46 for cleaning rotating rollers of a compactor, of which at least one roller is driven by a motor, for example, the ink roller 17 after the ductor roller 16, and of which at least one roller, for example 19, only by contact their Mantle surface is drivable with the lateral surface of one of the other rollers, and of which at least one roller is an ink roller for ink transfer.
- a motor for example, the ink roller 17 after the ductor roller 16, and of which at least one roller, for example 19, only by contact their Mantle surface is drivable with the lateral surface of one of the other rollers, and of which at least one roller is an ink roller for ink transfer.
- the cleaning device 46 includes a liquid applicator 48.
- This includes a manifold 49 having a plurality of liquid dispensing orifices 50 disposed along a first one of the rollers, e.g. B.
- the ink roller 18, which may be a motor-driven or a motor-driven roller, are positioned at a distance from her or positioned to liquid on the Apply lateral surface of the roller 18. This liquid is transferred by rotation of this roller 18 on the standing in mantle with her other rollers and from these rollers on other rollers in contact with them.
- the discharge openings 50 may be bores or nozzles used in bores.
- Liquid may be solvent, detergent, detergent or solvent-containing water, water with one or more additives which affect the printing process, pure water or any other liquid. Furthermore, the type of liquid can be changed during the washing process. For example, initially detergent or solvent or water containing it may be used to dissolve the paint from the rolls, and then rinsed with clean water.
- the liquid discharge openings 50 are small in size and shape such that liquid can only be applied to discrete moistening longitudinal zones 52 of this first roller 18, leaving non-moistening longitudinal zones 54 therebetween on this first roller 18.
- the width of a longitudinal moistening zone 52 is equal to the width of a liquid jet.
- the cleaning device 46 includes a liquid supply means 56 for supplying liquid to the discharge openings 50 and from there to the lateral surface of the first roller 18 in such an amount of liquid that the rotation of the rollers, the liquid from the discrete Befeuchtungszonen 52 of the first roller 18th on the lateral surface of the voltage applied to its lateral surface further roller, in the present example, the rollers 17 and 19, is transmitted.
- the liquid is transferred from the longitudinal moistening zones 52 of the first roller 18 to longitudinal moistening zones of the at least one further roller 17 and 19, leaving non-moistening longitudinal zones thereon.
- the amount of liquid per unit time of the discharge ports 50 may be constant or variable.
- Fig. 1 shows the liquid jets 51 only schematically.
