Definitions
- the invention relates to an application device for a printing / coating unit in a processing machine according to the preamble of claim 1.
- the processing machine is preferably a printing machine with printing units and preferably combined with at least one coating unit or a coating machine with at least one coating unit.
- An application device of this type is known from EP-0 090 179 B1 for preventing roller strips (in the printing result) in a roller unit of a printing press.
- roller strips result, for example, from impacts that occur when the rollers roll on a plate cylinder with at least one cylinder channel.
- the applicator roller is supported by resilient pressure pieces against an adjacent, upstream roller and, in addition, resilient pressure pieces are also assigned to this upstream roller.
- the spring forces of all pressure pieces are designed in such a way that the bearing play in the application roller is shifted to the side facing away from the upstream roller and in the upstream roller to the side facing away from the application roller.
- an inking roller which is functionally connected to a forme cylinder with a tensioning channel and which rolls on the forme cylinder with high damping and almost vibration-free.
- this roller carries an elastic roller train on a core as a color-carrying cover layer.
- the contour of the roller core has a recess (recess) which is assigned to the clamping channel of the forme cylinder and which is filled by a thickening of the roller cover.
- the inking roller has a completely cylindrical jacket on its outer circumference.
- the disadvantage here is the high manufacturing effort and that the thickening of the roll cover must always be operated synchronously with the tensioning channel. Furthermore, the damping behavior that can be achieved at higher machine speeds and / or larger format widths of the printing material is inadequate.
- the object of the invention is to create an application device of the type mentioned at the beginning which Avoids disadvantages, which in particular reduces the occurrence of impacts when passing through a cylinder channel and further increases the pressure quality.
- a first advantage is based on the fact that the application device with at least one application roller has a noticeably improved damping behavior compared to the impacts resulting from the passage of a cylinder channel. Due to the design of the application device, no or only negligible vibrations in the neighboring ones Transfer roller groups or cylinders. Furthermore, the formation of roller strips on the printed product can be avoided and thus an increase in the print quality (or varnishing quality) can be realized.
- the application device with at least one application roller permits the operation of a processing machine at increased machine speed, in particular with larger format widths of the printing materials, without vibration.
- the application device with at least one application roller can be used universally on processing machines with a forme cylinder and at least one cylinder channel.
- the application device can preferably be used on inking units, for example offset and / or flexo inking units. In offset printing supported by dampening solution, the application device can also be used in dampening units.
- the application device can also be used in coating or flexographic printing units.
- the application device is always functionally connected to a forme cylinder or plate cylinder with preferably at least one cylinder channel.
- the application device can be operated with at least one application roller, preferably in the inking unit and / or dampening unit, with a peripheral speed that differs from the forme cylinder.
- the application roller can be driven with a friction fit to the forme cylinder and the adjacent roller, for example the friction roller, can be driven with a positive fit.
- At least one application roller of the application device has a compressible layer that is effective over the entire roller circumference during the unrolling.
- the applicator roll here has a roll core on which the compressible layer is arranged concentrically adherent and on this compressible layer an elastic cover layer guiding the medium to be processed (paint, varnish, dampening solution) is arranged concentrically adherent.
- the applicator roller designed in this way dips into this and into the channel edges.
- the compressible layer of the application roller sufficiently elastic restoring force, so 'that "the basic roll setting in particular the predetermined roller strip (Walzenbei too) on the adjacent plate cylinder is again ingestible.
- the compressible layer of the applicator roll consists of A foam material with a cellular structure.
- the pore diameter of a cell is preferably approximately 0.1-5 mm.
- the structure can be closed-cell, ie the individual cells form closed cavities or open-cell, ie the cells are connected to one another.
- a foam material can be used with mixed cell structure.
- Fig. 3 shows an applicator roller of the applicator in cross section.
- the inking unit 3 has, inter alia, at least one inking roller train, which has a plurality of application rollers as inking rollers 6 at the end.
- the inking rollers 6 are preceded by axially changeable and rotationally drivable friction rollers 8.
- inking rollers 6 are frictionally assigned to this forme cylinder 1 in the direction of rotation of a forme cylinder 1 embodied here as a plate cylinder.
- first and second inking rollers 6 are in frictional contact with an upstream first friction roller 8 and the third and fourth inking rollers 6 are in frictional contact with an upstream second friction roller 8.
- the forme cylinder 1 has at least one axially parallel cylinder channel 10, for example for receiving clamping means for fixing printing forms.
- the forme cylinder 1 is also in contact with a blanket cylinder 2 and the blanket cylinder 2 is in contact with a printing cylinder, not shown, which guides the printing material, for example a sheet guiding cylinder.
- the dampening unit 4 is arranged upstream of the inking unit 3 in the direction of rotation of the forme cylinder 1.
- the dampening unit 4 has at least one applicator roller, which can be brought into contact with the forme cylinder 1, as the dampening applicator roller 5, which is functionally connected to an upstream dampening solution metering system.
- the coating unit 2 shows a coating unit, alternatively a flexographic printing unit, with a forme cylinder 1 with at least one cylinder channel 10 and a printing cylinder 11, for example a sheet guiding cylinder, which is in functional connection with the forme cylinder 1 and guides the printing material.
- the coating unit has at least one application roller, which can be brought into contact with the forme cylinder 1, as a coating application roller 7, which is coupled to a metering system 9 for the medium to be processed (flexographic printing ink, coating), for example a doctor blade or roller system.
- an application roller 5, 6, 7 (dampening application roller 5, ink application roller 6, lacquer application roller 7) is shown in cross section.
- This applicator roller 5, 6, 7 has a roller core 12 (with roller pins arranged at the ends) as the carrier material.
- a compressible layer 13 is arranged concentrically on the roller core 12, on which in turn a cover layer 14 carrying the respective medium (paint, lacquer, dampening solution) is arranged concentrically in a firmly adhering manner.
- the compressible layer 13 is preferably an open-cell or closed-cell, alternatively a mixed-cell, foam material. Furthermore, the compressible layer 13 can be designed with bubble-shaped or channel-shaped air or gas inclusions.
