Definitions
- the invention relates to a cylinder printing unit, in particular for the precise coating of sheets or sections by full-surface painting or Aussparlackieren (partial painting).
- Screen printing methods for example flat screen printing or rotary screen printing, are widespread. Although the latter has a high printing capacity, often only continuous paper can be used at high throughput speeds.
- EP-B-1066159 a method and apparatus for coating sheets and sections, with which the qualitative standard of Flachsieb horres also be achieved by means of a round screen and high performance, this arches or Sections taken from a stack and forcibly fed.
- the circulation of a round screen should be adjustable with respect to the fed sheets or sections to achieve a precise pass during the printing process and a synchronization between continuous sheets and exact coating.
- a constant conveyor is provided and the round screen has a controllable drive.
- the round screen is also quickly changeable, for which purpose the screen cylinder can be lifted off the impression cylinder.
- the round screen is also adjustable for diagonal repeat and longitudinal repeat.
- DE-U-9102128 discloses a register system for flexographic and screen printing with a flexo cliche and a, over the entire length of the pressure field extending pass hole bar and a second pass hole bar with a corresponding passport system register fit.
- the invention is based on the object, a cylinder printing unit resp.
- a flexo-varnishing unit that enables a combination of rotary screen printing and flexographic printing (offline sheet-fed).
- the scope of a device according to EP-B-1066159 is to be increased. The solution of the problem is achieved with the features of the claim.
- the printing unit has a clamping mechanism, which is suitable for both a screen-printing cylinder and a flexographic printing cylinder with high registration accuracy to be used or quickly interchangeable.
- a flexographic printing cylinder should be used identically to a round screen in the same attachment and clamping device of a screen printing analogous to the screen.
- the flexographic printing cylinder consists essentially of two laterally arranged bearing flanges and a fixedly connected therebetween cylinder.
- the cylinder has a sunk in the lateral surface arranged clamping device for the suitable recording of blankets or printing plates.
- a flexographic printing cylinder which consists of two laterally mounted bearing flanges and a sleeve arranged between them (rubber-coated tube).
- the flexo cylinder with clamped blanket is preferably used for full-surface painting with low paint application quantities or for 'inaccurate' Aussparlackmaschineen, such as Klebelaschenaussparlackmaschineen where register accuracies of +/- 0.5 - 1.0mm are required.
- the flexo cylinder can also be used for precision recess finishes where register accuracies of ⁇ +/- 0.1 mm are required.
- Existing screen printing machines with screen printing cylinders can be retrofitted with an optional combination coating unit with chambered doctor blade coating system and flexographic printing cylinder.
- the paint application system with an anilox roller is pivotable on the flexographic printing cylinder.
- An apparatus for coating and coating of sheets in addition to the usual components, not shown, as disclosed for example in EP-B-1066159, a roller scheme consisting of a flexo cylinder 1, a counter-pressure cylinder 2 and a pivoting arm 3 on.
- the pivot arm 3 comprises its pivot point 32, an anilox roller 30, a chamber doctor blade 31 with storage, an unspecified delivery and drive the anilox roller 30 and a drip tray 34.
- This paint application device can be pivoted with the anilox roller 30 on the flexo cylinder 1.
- the flexographic printing cylinder 1 can be surrounded both with a rubber blanket or a printing plate (for example according to EP-B-1066159).
- the blanket 10 is preferably armored and symmetrical and will as well as the pressure plate to the outer surface the flexographic printing cylinder 1 stretched.
- a, in the jacket of the flexographic printing cylinder 1 recessed clamping device is provided, which is arranged parallel to the axis of rotation of the flexographic printing cylinder 1.
- This comprises two tensioning rails 11, between which a plurality of tensioning devices 13 are arranged, two fixing rails 12 for covering the transition between the rubber blanket 10 and the inserted tensioning rail 11.
- the end faces of the flexographic printing cylinder 1, which has a shaping circular tube 15, are covered by bearing flanges 14.
- a dynamic register correction in the run is possible.
- the flexographic printing cylinder 1 is also stored to increase the running accuracy.
- the flexographic printing cylinder can be mounted identically to a screen-printing cylinder in the screen printing plant and thus enables, in addition to the achievement of a combined printing or combi-coating plant in new systems and retrofitting existing systems, including the chambered doctor blade applicator.
- the paint is applied by means of chamber doctor blade 31 to the anilox roller 30. This transfers the paint from the outside to the clamped blanket 10 (cliché) and this the paint on a sheet, not shown.
- the paint is conveyed directly into the interior of the screen cylinder and applied by means of a doctor blade through the screen openings (from the inside to the outside) onto a sheet to be printed.
- a change between screen printing and flexo printing takes place by replacing the complete screen printing cylinder resp. Flexographic printing cylinder 1, for which a clamping mechanism is actuated (not shown).
