printing unit

The invention relates to a printing unit according to the preamble of claims 1 or 3.

GM 84 10 619 U1 discloses a printing unit of an offset rotary printing machine with two horizontally movable forme cylinders, which can optionally be adjusted to a common and stationary transfer cylinder and a common stationary applicator roller.

EP 00 26 628 A1 also shows an impression unit with two forme cylinders which have a common, stationary inking roller. The two forme cylinders can be moved horizontally as a pair and can thus be adjusted against the inking roller and a common satellite cylinder wrapped in a paper web.

EP 07 49 369 B1 discloses a printing unit, wherein four right and four left printing units are arranged one above the other. The four right printing units are located in a frame part that can be moved horizontally. In the closed position, the right and left printing units each form a bridge-type printing unit in pairs.

The US 61 19 593 A shows two forme cylinders with two roller inking units arranged in a frame, which between a first position, in which the first forme cylinder with the transfer cylinder not located in the frame, and a second position, in which the second forme cylinder cooperates with the transfer cylinder , is movable. The ink application and distribution rollers assigned to each of the forme cylinders have a common ink feed.

DE 198 33 470 A1 shows satellite printing units from offset printing which in order to increase the possible uses, e.g. B. either as a 9-cylinder printing unit or as a 5-cylinder printing unit, modular design, and the modules are designed to be movable.

DE 197 50 886 C1 discloses a sheet-fed rotary printing press, printing units being movable away from the interacting impression cylinder for the purpose of accessibility. Each printing unit has its own ink supply, which colors the assigned form cylinder and the assigned transfer cylinder.

DE 39 17 340 A1 shows an offset printing unit which is suitable for the flying elevator change, with two forme cylinders being assigned a transfer cylinder and an application roller. The printing unit has a roller inking unit and a dampening unit.

The invention has for its object to provide a printing unit.

The object is achieved by the features of claims 1 or 3.

The advantages that can be achieved with the invention are, in particular, that a wide range of uses for a wide variety of printing presses and thus good standardizability is achieved.

The compact design of a printing unit as a module, in particular using an anilox inking unit, for example even without an additional inking roller and, for waterless offset printing or flexographic printing, without a dampening unit, enables use in a wide variety of printing press types.

For example, a printing unit that is designed for high-pressure printing can be used in a printing machine that is essentially designed with offset printing units. An embodiment is also advantageous, wherein two forme cylinders assigned to a transfer cylinder can be optionally colored by a common inking unit. By arranging only one inking unit, in particular an anilox inking unit, the outlay and costs are kept as low as possible. In particular, the small dimensions, the low weight and the simple structure enable the execution as a module, which, for. B. for the purpose of turning on and off in the printing unit.

When interacting with conventional printing units or units and / or when integrating into an overall system, the compact basic dimensions of the module make it possible to compensate for different heights using filler pieces.

The arrangement of two form cylinders which can be driven independently of one another and which alternately interact with only one blanket cylinder enables a flying printing form change without having to stop a web to be printed. Thus, when changing the impression, the pressure point on the same transfer cylinder is retained. The pivoting of the forme cylinder when changing from one impression to the other is also particularly advantageous, the transfer cylinder being able to remain stationary. This enables production to continue without the transfer cylinder and thus the printing point being moved during the change.

The printing unit designed as a module is advantageously designed as a high-pressure or flexographic printing unit with one or more corresponding high-pressure printing plates on the circumference of the plate cylinder designed as a plate cylinder. For the purpose of coloring the shape or The printing unit only has a plate cylinder with an anilox or anilox roller that works directly with the plate or plate cylinder. This works directly with an ink pan using a squeegee, e.g. B. a chamber doctor blade together. It is also possible to arrange an immersion roller between the ink tray and the anilox roller if the spatial conditions allow this. In a particularly advantageous embodiment, each cylinder of the printing unit is designed with its own drive motor, and is therefore independent of the drive of the other printing units of the printing press. At least one drive motor on each of the forme cylinders enables the drive to be driven during production and braking, set-up and acceleration again during the printing form change. Auxiliary motors and clutches can be omitted. Another advantage is the possibility of a relative register or register adjustment of the forme cylinders to each other.

In an advantageous embodiment, the printing unit designed as a module is arranged to be movable as a whole in a frame or a frame, in particular almost perpendicular to the course or to the plane of the paper web; z. B. vertically movable for the case of a printing line with a horizontally running paper web, and horizontally for the case of a vertically running paper web. The cylinders can be turned on or off to or from a cylinder of a cooperating printing unit without the position of the cylinders of the printing unit relative to one another being changed by the on / off process. The module which can be moved in this way simultaneously enables simple movements of two forme cylinders on a transfer cylinder and the turning on and off of the transfer cylinder on the counter-pressure cylinder. The movements of the forme cylinder, the module and the inking unit are completely decoupled from each other.

The interaction of the modular printing unit for the flying printing plate change with a second module of this type is advantageous. A flying change of printing form on both sides of the paper web is possible. If two modules form a printing unit, only one of the two modules has to be arranged to be movable.

Due to its compact design, the module can also be integrated into a printing press, in which it interacts with a conventional offset printing unit. The forme cylinder or cylinders of the module then have, for example, high-pressure printing forms, and the forme cylinder of the offset printing unit has an offset or planographic printing Printing form on. A possibly missing height when using the module instead of a conventional printing unit is e.g. B. can be compensated again by means of fillers.

The printing unit can be used in various printing units, such as. B. a so-called rubber-to-rubber operation printing four-cylinder or bridge unit, an eight-cylinder printing unit (H-printing unit or two vertically arranged four-cylinder printing units or double printing units arranged side by side), a so-called eight-tower, a nine- or ten-cylinder printing unit , e.g. B. a satellite printing unit with one or two counter-pressure cylinders designed as satellite cylinders.

The interaction of a modular high-pressure printing unit, which has only one forme cylinder assigned to the module, with an offset or planographic printing unit also offers great advantages due to its standardizability and the small space requirement.

Embodiments of the invention are shown in the drawings and are described in more detail below.

Show it:

2 shows a printing unit with two printing units arranged one above the other, designed as a module, for the flying printing form change in the print-on position;

3 shows a printing unit with two printing units arranged side by side as modules for the flying printing form change in the print-down position; Fig. 4 shows a printing unit with a printing unit designed as a module for the flying printing form change and an offset printing unit in the print-on position.

A printing unit 01 of a rotary printing press, in particular an offset printing press, has a printing unit 02 with a web 03, e.g. B. a substrate or paper web 03 interacting cylinder 04, z. B. a transfer cylinder 04 on. The transfer cylinder 04 has two cylinders 06; 07, in particular two forme cylinders 06; 07 assigned, which can optionally be adjusted to the transfer cylinder 04 and then interact with it. Starting the forme cylinder 06; 07 is advantageously carried out via a linear actuating device, not shown. The setting can also be done via a stroke of an eccentric bearing (not shown in the figures) for the forme cylinders 06; 07 done. The two forme cylinders 06; 07 each have their own drive motor which is independent of the transfer cylinder 04 but is not shown in the figures. In the example, the transfer cylinder 04 also has its own, one of the forme cylinders 06; 07 independent drive motor, not shown in the figures.

The two forme cylinders 06; 07 is assigned a common inking unit 08, which can optionally be used with one of the two forme cylinders 06; 07 works together.

In a first exemplary embodiment (FIG. 1), the inking unit 08 is designed as an anilox inking unit 08, which has an ink fountain 09 and one with one of the forme cylinders 06; 07 cooperating roller 11, in the example an anilox roller 11, for. B. has an anilox roller 11. Instead of an ink fountain 09, a doctor blade 09, in particular a chamber doctor blade 09, can also be arranged. In an advantageous embodiment, the inking unit 08 has its own, from the forme cylinders 06; 07 independent drive motor. The inking unit 08 can, however, also be driven together with the transfer cylinder 04.

The transfer cylinder 04, the two forme cylinders 06; 07 with its facilities for Switching on and off, the inking unit 08 and the drive motors are part of the printing unit 02 designed as a module 02 and are, for example, in a common frame 12, for. B. a frame 12 or a housing 12 is arranged.

In this context, a “module” is understood to mean a complex part of a machine, for example the printing press, in particular a printing unit, which forms a functional unit. U. represents a whole replaceable and / or movable unit.

Within the module 02, the transfer cylinder 04 is mounted in a fixed but rotatable manner and extends in the radial direction of the transfer cylinder 04 with a lateral surface 13 on its bale from the cross section of the module 02. The roller 11 is for the purpose of turning on and off both forme cylinders 06; 07 almost along a movement line W, the connecting line of axes of rotation R04; R11 of the transfer cylinder 04 and the roller 11, movable. The two forme cylinders 06; 07 are arranged to be movable along a movement line F, so that they can be adjusted to the transfer cylinder 04 and the roller 11 in a position of contact. In an advantageous embodiment, the movement lines W and F are almost perpendicular to one another. The movement line F advantageously connects the axes of rotation R06; R07 of the two forme cylinders 06; 07 in the position parked by the transfer cylinder 04.

For the pressure-down position AB (Fig. 1) or pressure-on position AN (Fig. 2) of the transfer cylinder 04 to a cylinder 14 acting together via the web 03, z. B. a second transfer cylinder 14, a cooperating printing unit 17, the entire module 02 is movably arranged in a frame 16 along a movement line M, the position of the cylinders 04; 06; 07 and the roller 11 do not change to each other. For this reason, it is advantageously possible to carry out simple linear movements within the module 02 without, for example, for the forme cylinders 06; 07 and / or the roller 11 double eccentric or two Linear movements are required for tracking. A device for guiding or pivoting can be omitted for the transfer cylinder 04. ,

In the first exemplary embodiment (FIGS. 1 and 2), the printing unit 02 designed as module 02 interacts with the second printing unit 17, also configured here as module 17, module 17 being advantageously arranged below module 02 in the same frame 16. In the print-on position AN, the cooperating transfer cylinders 04; 14 a pressure point. The modules 02; 17 are arranged in the frame 16 so that the bales of the two transfer cylinders 04; 14 face each other. In the example, the module 02 can be moved vertically along the movement line M in and against the direction of the module 17 arranged below it, while the module 17 is arranged stationary in the frame 16. Fig. 1 shows the module 02 in the pressure-down position AB and Fig. 2 in the pressure-on position ON. Within the module 02, the forme cylinders 06; 07 and the roller 11 turned off. In Fig. 2, the right forme cylinder 07 is placed on the transfer cylinder 04 and the roller 11. The roller 11 is also in a position of adjustment along its movement line W.

Corresponding to module 02, transmission cylinder 14 is stationary in module 17 with respect to module 17, and two further cylinders 18; 19, in particular two forme cylinders 18; 19, horizontally movable and a second roller 21 of a second inking unit 22, for. B. also an anilox roller 21, in particular an anilox roller 21, arranged vertically movable. A roller 23 or a doctor blade 23 is assigned to the roller 21. The cylinder 14; 18; 19 and the inking unit 22 are in an advantageous embodiment as a module 17 again in a frame 24, for. B. a frame 24 or a housing 24 arranged.

The two modules 02; 17 together form the printing unit 01, with the possibility for a flying printing form change or for an imprinter function during printing operation being provided on both sides of the web 03. If a flying printing form change is not necessary for the ongoing production, the printing unit 01 is a full printing unit 01, e.g. B. can be used for another color. In the example, the printing units 02; 17 as high-pressure or flexographic printing units 02; 17 executed for high pressure or flexographic printing, the z. B. designed as a rubber cylinder transfer cylinder 04; 14, the form or plate cylinder 06; which holds a plate or one or more high-pressure printing plates; 07; 18; 19 and the anilox roller 11; 21 have the same diameter.

In order to compensate for height differences in the guidance of the web 03 to the other printing towers in a printing machine having a plurality of printing towers side by side or one behind the other in a horizontally running web 03, a corresponding filler 26 can be arranged below the lower module 17 or below the frame 16. The printing unit 01 can be integrated, for example, in a printing line made up of printing units for offset printing.

The two to a common transfer cylinder 04; 14 form cylinder 06; 07 or 18; 19 can be movable along their movement line F for each of the exemplary embodiments, either individually or in pairs, as indicated schematically in FIG. 2 for module 02.

In a second exemplary embodiment (FIG. 3), the two modules 02 and 17 are not arranged one above the other but next to one another in the frame 16, here the left module 02 being horizontally movable in the frame 16 and the right module 17 being arranged stationary. Fig. 3 shows the module 02 in the print-down position AB. The web 03 runs vertically between the two transfer cylinders 04, 14. Such a horizontally oriented printing unit 27 can be used, for example, instead of one or in addition to one or more conventional bridge printing units in stacked construction with the web 03 running vertically in web offset printing presses. If necessary, differences in the overall height can be compensated for again using filler pieces 28.

For the structure and the movements within module 02; 17 is for the first Embodiment executed accordingly to apply.

In a third exemplary embodiment (FIG. 4), the printing unit 02 designed as a flexographic printing unit 02 acts as a module 02 with a cylinder 29, e.g. B. a transfer cylinder 29 of a printing unit 31, in particular a printing unit 31 for planographic printing, z. B. an offset printing unit 31, which, in addition to the transfer cylinder 29 and another cylinder 32, z. B. a forme cylinder 32, a dampening unit 33 and an inking unit 34, z. B. has a roller inking unit 34. The forme cylinder 32 has one or more printing forms for planographic printing. The inking unit 34 can be a film or lifter inking unit or also an anolox inking unit 34 for offset printing, a so-called short inking unit. The dampening unit 33 can be omitted, in particular for waterless offset printing. The two printing units 02; 31 together form a printing unit 36 which is suitable for one-sided imprinter operation or a one-sided flying printing form change.

In the example, the module 02 is arranged to be vertically movable above the printing unit 31, the web 03 being arranged horizontally between the transfer cylinders 04; 29 runs. A print-on position AN is again carried out by moving the entire module 02 along the movement line M in the direction of the printing unit 31. In the print-on position AN, the cooperating transfer cylinders 04; 29 a pressure point. Fig. 4 shows the module 02 designed as a flexographic printing unit 02 in the print-on position ON.

In an advantageous embodiment, the vertically movable module 02 and the stationary printing unit 31 are arranged within the common frame 16. However, both the printing unit 31 and the movable module 02 can each be arranged in their own frame, not shown.

For the structure and the movements within the module 02, the statements made for the first exemplary embodiment are to be applied accordingly. As shown in the second exemplary embodiment (FIG. 3) for the printing unit 27, the printing unit 36 can also be arranged horizontally, with a course of the web 03 being vertical, and the module 02 and the printing unit 31 being arranged next to one another.

The module 02 designed as a printing unit 02 for the high pressure can also have only one forme cylinder 06 equipped with one or more high pressure printing plates. In this case too, the modular and compact printing unit 02 can be adjusted as a whole to the offset printing unit 31, but is not suitable for the flying printing plate change.

It is also possible that module 02; 17 with a counter-pressure cylinder 14; 29 executed cylinders 14; 29, e.g. B. a steel cylinder, without another pair of cylinders and an inking unit forms a printing unit, not shown in the figure, for one-sided printing of the web 03. In this case, however, it can be advantageous if the impression cylinder 14; 29 to module 02; 17 to the pressure on or pressure down position ON; AB to transfer cylinder 04 of module 02; 17 is moved towards or away from this, and the module 02; 17 is designed as a stationary module 17.

Module 02; 17, or its transfer cylinder 04; 14 can also with an impression cylinder 14; 29 cooperate on which at least one further cylinder, for. B. another cylinder pair with inking unit can be adjusted.

The function of the printing unit 02; 17 for the flying printing plate change using the example of module 02 is as follows: (The starting point is the printing unit 02 in the print-down position AB, both of the forme cylinders 06; 07 being switched off from the transfer cylinder 04 and the roller 11 from the forme cylinders 06; 07 is turned off.)

One of the two forme cylinders 06; 07, e.g. B. 06 is equipped with a printing form, not shown, and pivoted or moved linearly along the movement line F in the direction of the movement line W of the roller 11 until the forme cylinder 06 to the Transfer cylinder 04 is employed. The roller 11 is pivoted or moved linearly along the movement line W in the direction of the transfer cylinder 04 until the roller 11 is in contact with the forme cylinder 06. For the purpose of printing-on position ON, the entire module 02 previously accelerated to production speed is moved along the movement line M in the direction of the cooperating printing unit 17; 31 moves. The designs for the movements of the cylinders 06; 07 and the roller 11 are correspondingly on the cylinder 18; 19 and to apply the roller 21 of the printing unit 17.

For a flying printing form change, a printing form is arranged on the parked second form cylinder 07 and the form cylinder 07 is accelerated to production speed. While the forme cylinder 07 is pivoted or moved linearly between the roller 11 and the transfer cylinder 04 for the purpose of being positioned, the first forme cylinder 06, which is in production, can be switched off by the roller 11 and the transfer cylinder 04. If the module 17 is designed to be movable, the explanations for the movement of the module 04 are to be applied accordingly to the module 17.

A print-down position AB of the printing unit 01; 27; 36 takes place by moving the entire movable module 02 away from the cooperating printing unit 17; 31st
