Description

The invention relates to a method for using a newspaper printing press according to the features of claim 1.

In the DE 10 2005 015 197 A1 is a printing tower of a newspaper printing machine disclosed which is designed for newspaper printing with printing units in dry offset. In one embodiment, the printing units have a single-roller inking unit with metering pump device. In this case, the forme cylinders are preferably cooled and / or kept at a constant temperature in order to avoid toning under changing operating conditions during printing. A tempering is also preferably provided for the distribution cylinders of the inking unit, wherein the temperature control preferably takes place from the inside by means of a suitable fluid such that the surface area of the distribution cylinders is maintained within the temperature range between 22 ° C. and 40 ° C. and the surface area of the forme cylinders in the temperature range z. B is maintained between 20 ° C and 30 ° C. For a trouble-free printing is a tack with a tack value between 2 and 16, z. B. between 6 and 9.5, in particular between 7 and 8.5 strive, the values of the respective test equipment depend. The tack can be tested by testing equipment such. B an Incomer or a Tackomat Fa. Prüfbau be determined.

Such a range for the speed between 6 and 9.5, in particular between 7 and 8.5, is also in the WO 03/045694 A1 discloses in connection with an inking unit of a newsprint printing unit, wherein the ink is supplied from a paint supply via an anilox roller to the forme cylinder.

The WO 2005/097504 A2 discloses a multitude of modularly assembled Printing towers, in some embodiments, the printing units of the printing tower are designed as waterless offset printing works for newspaper printing. In various variants, inking modules can be provided, which are designed as a short inking unit, as einzughiges roller inking unit or as a two-pass roller inking unit. U. a. is in a variant according to Fig. 8 discloses a teibarer printing tower for newspaper printing with printing units in dry offset, which have a single-roller inking unit. Three of four cylinders of the double printing units are preferably linearly adjustable in linear bearings for the purpose of pressure on / off positioning.

By the WO 2006/072558 A1 is a printing towers having printing machine for waterless printing of uncoated or lightly coated newsprint known, the printing units are formed with anilox rollers having short inking units. For ink flow control, the anilox rollers can each be tempered individually via inner temperature control circuits, which can be fed from supply circuits. The forme cylinders of the printing tower can be tempered individually, in pairs or in larger groups by means of temperature control circuits that can also be fed from supply circuits.

In the WO 2009/097912 A1 a printing tower of a printing machine is disclosed, wherein the printing unit is formed with a width of at least two stationary newspaper pages and the inking unit as a short two-row roller inking unit with a close to the dampening unit and a dampening remote drive cylinder in two parallel pulleys.

The DE 10 2008 064 635 A1 discloses a printing press line with an anilox roller printing tower of a first waterless printing machine for printing either newsprint or higher quality paper. A printing tower of a second, newsprint-printing machine line is conventionally formed with roller inking units and dampening units, whereby webs or partial webs originating from both machines can be guided on a common funnel structure. The dry offset printing units used in the anilox rolls used Ink has at 25 ° z. B. a viscosity of at least 120 Pa * s, in particular at least 150 Pa * s.

The EP 0 652 104 A1 discloses a waterless I-printing unit of a commercial printing machine, wherein the two transfer cylinders of the printing unit by a tempering, the two forme cylinders of the printing unit by a tempering, the distribution cylinder of the double printing by a temperature control and the ink fountain rollers are tempered by a tempering. In the respective temperature control a temperature control of the components to be tempered is regulated by the fact that the circulating volume flow is varied. The printing plate is tempered here to about 28 to 30 ° C, the inking unit to about 25 to 27 ° C.

The US 2002/0112636 A1 relates to a horizontal web-fed rotary printing machine, as is common for commercial printing. The wet or dry offset printing units arranged horizontally one behind the other are designed to be tempered by passing tempering fluid through a dividing flow line from a fluid reservoir to the inking units of the printing units, wherein the fluid flow can be adjusted by valves provided in the respective return line for temperature control. In a further development, the form cylinder of the same printing unit is tempered by the same supply line parallel to the inking rollers of the same circuit. Alternatively, the flow rate of all parallel, tempering the printing units branches can be varied before their division by a controllable valve via a bypass line.

The DE 602 02 551 T2 relates to a waterless offset printing machine for a multi-color overlap printing, wherein the form cylinder cooperate with a common transfer cylinder. Each forme cylinder is an inking unit with a plurality of fluidized by fluid via a secondary system line friction cylinders, and assigned via a first system line temperable ductor and a transfer roller. The forme cylinders are cooled by injected air.

The invention has for its object to provide a method of using a newspaper printing press with printing tower.

The object is achieved by the features of claim 1.

The achievable with the present invention consist in particular in that a printing tower with inking units having printing units for newspaper printing and such a printing tower having newspaper printing machine is created, which at reasonable cost allows trouble-free waterless printing using newsprint, especially natural papers.

On the one hand, optimal color application (without toning and no plucking) is achieved by means of a special design of the printing tower temperature control, while for the tempering of inking unit rollers reduced expenditure is required for stable processes.

By using a printing ink of special properties and / or setting specially selected temperature levels for the components, a sufficiently good color flow can be achieved in the roller inking unit, and at the same time a toning on the printing form can be prevented, and preference can be given to tempering transfer cylinders.

The special architecture of the tempering, for example, associated with the pressure tower primary circuits and individually controllable secondary circuits -. B. for individual form cylinder or form cylinder pairs -, with at least one preferably Inking roller of several arranged on the same side of the web printing units associated secondary circuit and possibly with a the pressure towers associated primary circuits connecting higher-level circuit, an effective, responsive and needs-based temperature control is created. This ensures trouble-free printing on natural or newsprint, z. B. already in a startup phase of the printing press.

By forming the inking unit as a roller inking unit, in comparison to anilox rollers having inking units, a printing ink which is more strongly adapted to the ink application to the forme cylinder and / or to the printing material can be used without the amount of ink to be conveyed being decisively influenced. By using a zonally adjustable metering device, in particular a color box with zonally adjustable control elements, the color input viewed in the axial direction can be influenced in a targeted manner. Furthermore, it is not necessary to control the color input by varying the temperature. The temperature control can thus be completely decoupled from the required color flow. For example, it is possible to realize a lower tack of the printing ink in the area of the forme cylinder while at the same time increasing the viscosity of the printing ink in the area of the inking unit. The temperature in the inking unit can thereby be chosen even contrary to the requirements of the forme cylinder. For example, the temperature at the forme cylinder is set lower than that at the at least one tempered distribution cylinder of the inking unit.

In particular, the formation of the inking units in their arrangement de rollers offer advantages in terms of good trituration with minimum space requirements and contamination. The special design of the Reibzylinders has advantages in terms of good homogenization of the temperature. The same applies to the formation of the forme cylinder.

Of particular advantage is also an embodiment and / or operation of z. B. a plurality of such printing towers having printing machine, wherein a printing tower while maintaining a same ink type without replacing the ink optionally in heatset mode, eg. B. with a heatset web, and in coldset operation, for. B. with a coldset web, operable or operated. Also advantageous is the mode of operation, wherein a coldset web or partial web printed in the coldset in a dry offset printing tower is brought together on a hopper assembly together with a heatset web or partial web printed in the heatset in a dry offset printing tower.

Embodiments of the invention are illustrated in the drawings and will be described in more detail below.

A printing machine, in particular a printing press designed in the manner of a newspaper printing press, has at least one printing group 01 for double-sided printing on both sides of a web 02, e.g. B. paper web 02, but preferably several, z. B. at least two, advantageously z. B. at least three groups of printing groups 01 for the two-sided multicolor printing of several at the same time, z. B. at least two, advantageously z. B. at least three tracks 02, on. At least one reel unwinder 03, in particular reel changer 03, is provided per web 02 or per printing unit group 01, from which the respective web 02 can be unwound and supplied via corresponding guide elements of the respective printing group 01 (see eg Fig.1 ).

The printing unit groups 01 of the "newspaper printing press" are distinguished, in contrast to the illustration printing, preferably by their design as so-called printing towers 01, in which the webs 02 guided through them are guided (predominantly) vertically. The respective printing tower 01 has z. B. all required for a double-sided multi-color printing web 02 required pressure points 10. For a four-color printing on both sides, the printing tower 01 has at least eight individual (printing areas) 10 or four double printing sites 10. Preferably, at least two or at least three printing towers 01 are in the same machine alignment. By this design of the printing machine are on a small footprint at least two, three or more webs 02 simultaneously printable and after printing together on a same hopper assembly 04 for common further processing in z. B. a folder 06 (eg., Cross folder for transverse cutting and Querfalzen) feasible. Are the print groups 01 for printing more than two juxtaposed print pages, especially newspaper pages, z. B. four or six newspaper pages or printing plates wide, formed, for example, between the pressure point groups 01 and the funnel assembly 04 a turning tower 07 is provided with at least one pair of turning bars having turning tail. By merging a plurality of webs 02, the page numbers required in newspaper printing can be produced at least for the standard product in the inline process, ie without or at least without any significant subsequent gathering. Under "newspaper printing press" should also be understood such printing towers 01 having printing machines, which additional units, for. B. one or more dryers 05, have, and in principle also for printing higher quality substrates, eg. B. of webs 02 'higher quality in z. As a heatset operation are suitable. In contrast to a commercial press installation in which each horizontally extending web is associated with a dryer, none, or at least less dryer 05 than the number of printing towers 01 or webs 02 intended. The dryer 05 is z. B. as a radiation dryer (IR, UV) or in particular as a thermal dryer 05 formed. Advantageously, at least one web path without passing through a dryer 05 is provided per printing tower 01.

The printing machine is preferably characterized by the fact that, for. B. in at least one mode of operation (eg., In coldset operation), at least through one of the printing towers 01 a web 02 out and / or printed or printable, which preferably uncoated (or at least slightly coated) paper, preferably so-called Newsprint, machine smooth or calendered calendered, is formed. This type of printing material is also referred to below as "newsprint". In particular, these may be 02 simultaneously guided by a plurality of printing towers 01 simultaneously. The run in the coldset through the relevant printing tower 01 web 02, for example, by open-pored and / or possibly satin-finished and / or in particular wood-containing paper, eg. B. as so-called. "Natural paper" (ie with untreated, possibly mechanically satin finished surface), be formed. It may also contain a proportion of recycled waste paper (eg, at least 50% secondary fibers derived from recycled paper), or it may even be a web 02 made essentially of waste paper. The wood content (especially the lignin) of the newspaper contributes to the rigidity of the mostly large and thin pages of the finished newspaper product, while z. B. the open porosity of the newspaper a "knocking" of the color, and thereby less expensive production, usually without drying support by a specially provided and / or activated dryer allows. This thin newsprint paper has z. B. a basis weight according to ISO 536 preferably between 35 to 60 g / m ² , in particular 40 to 50 g / m ² for "normal" (machine-smooth) and 50 to 60 g / m ² for satin (eg., By calender) on. If the web 02 is formed from satined or possibly slightly coated paper, then it is not completely "sealed" but in the second case has z. B. a coating weight below 10 g / m ² , in particular at most 5 g / m ² . These papers, especially the uncoated or barely painted, have in common that they have open pores or at least none having a closed-pore surface and, in particular in the case of recycled paper (in whole or in part); z. B. (compared to only primary fibers having papers) shorter fibers. The thus formed, coldset printed or to be printed web 02 has, for example, a roughness according to Bendtsen (ISO 8791/2) of z. B. more than 70 ml / min (eg, simply satin), in particular of more than 80 ml / min (simply satin) or even at least 100 ml / min (machine smooth) on. However, this superficial fuzziness and / or roughness, in contrast to papers used in commercial printing, can cause individual fibers to be torn off by the "stickiness" of the ink, resulting in errors in printing and printing instead of error-free image transfer leads to contamination of the paint. In the case of the dry offset present here, the fibers are not transported away by dampening solution otherwise present in the wet offset. All this leads to great obstacles in the area of newspaper printing for the application of waterless offset printing or dry offset printing.

In order to meet the problem set out with the least possible technical and regulatory effort, and at the same time to ensure stable printing conditions and a high print quality for newspaper printing in the dry offset process, the printing press is at least the one with o. G. Paper operated or operated printing tower 01, executed in the manner described below with printing units 08 and inking 09 or operated.

The printing unit 08 is formed as a so-called "waterless" offset printing unit 08 without Fechtmittelquelle, ie formed without a dampening agent in addition to the ink additionally dampening dampening. Per printing unit 08 is a web 02 in print-on together acting printing cylinder 11, z. B. transfer cylinder 11, a respect. The colorway upstream with the transfer cylinder 11 cooperating printing cylinder 12, z. B. forme cylinder 12, and provided with this an upstream ink the inking unit 09.

The pressure point 10 is preferably formed by a pressure nip of the transfer cylinder 11 with a further printing unit cylinder 13, which serves the transfer cylinder 11 via the web to be printed 02 as an abutment. This third printing cylinder 13 can be designed as a pure, no ink leading impression cylinder, but advantageously as a second, ink-carrying transfer cylinder 13 of a second printing unit 08 with a second formed as a plate cylinder 14 printing group cylinder 14. This forms with the first printing unit 08 at each other over the web 02 salaried transfer cylinders 11; 13 a pressure point 10 designed as a double pressure point 10 for the simultaneous double-sided printing (see, for example, FIG. Fig. 2 ). In an advantageous embodiment, the centers of the two printing cylinder 11 lie in pressure-on position; 12 of the printing unit 08 and the third printing cylinder 13, in the embodiment with double pressure point 10, the centers of all four printing cylinder 11; 12; 13; 14, in a common plane E (see eg Fig. 2 ).

In the embodiment with counter-pressure cylinders, the pressure tower 01 having at least eight pressure points 10 can be configured, for example, with two stacked nine or ten-cylinder pressure units. In the illustrated advantageous embodiment, the printing tower 01 four double printing units 17 from two printing units 08, which can all be provided in a common frame, two double printing units 17 in two stacked racks, or a double printing unit 17 in four stacked racks. The double printing units 17 can be angled in deviation from the advantageous planar design (level E) in a conventional manner, z. B. all or mixed as n or u-printing units or as a respective n- and u-printing unit having H-pressure units may be formed. The double printing units 17 are designed lying, ie they extend in each case z. B. in predominantly horizontal orientation. In all cases, the printing tower 01 of the newspaper printing machine - in contrast to illustration printing units - one above the other several printing units 08 for a double-sided multi-color printing at least partially from bottom to top, ie substantially vertically, passing through the printing tower 01 web 02. For example, there are several, z. B. four, successively printing on the same side of the web 02 printing 04 - in particular one above the other - arranged.

In an advantageous, not explicitly shown embodiment of several, z. B. four double printing units 17 on top of each other printing tower 01 in the region of its pressure points 04 so formed teibar that a resulting in an open position space between the transfer cylinders 11; 13 can be entered by operating personnel. For this purpose, the printing cylinder 11; 12; 13; 14 and ancillary units (eg inking units 09) on the one side of a web 02 to be carried out or carried out by the printing tower 01, in each case on the front side on first frame sections and the printing unit cylinders 11; 12; 13; 14 and ancillary units (eg inking units 09) which are mounted on the other side of the web 02 in each case on the front side on second frame sections. The first and second frame sections carrying these printing unit units are mounted on a ground plane in such a way that a distance between the first and second frame sections can be changed. Preferably z. B. first frame sections away from the pressure point direction (maintenance position) and in pressure point direction movable (operating position), while the second frame sections are arranged stationary. The divisibility of the printing tower 01 allows a more crowded design than only externally accessible printing towers 01 and therefore an extremely short distance between the printing areas 10, ie between the first and last printing location 10, so that a result of inking "growth" of the web 02 between the first and last nip 10 is reduced to a minimum. This is especially true in the context of porous, d. H. z. As undrained or slightly coated substrate in which moisture contained in the ink penetrates faster and which is more susceptible to growth due to its (unprotected) fiber structure.

Basically, this is i. V. m. the waterless offset printing, in particular newspaper offset printing, Also mentioned on printing presses or printing towers 01 or Druckwerke 08 and apply to their operating situations or operations mutatis mutandis, which indeed have a dampening unit, but this is set in the relevant operating situation or mode of operation out of service.

The two printing cylinders 11; 12 and 13, respectively; 14 of a printing unit 08 are mechanically driven by at least one drive motor 15 independently of the other printing units 08 of the printing tower 01. This can be done in pairs by a common drive motor 15, or preferably by individual, each of the other printing cylinder 11; 12; 13; 14 and of the inking units 09 mechanically independent drive motors 15 take place.

The transfer cylinder 11; 13 has on its circumference at least one, possibly up to a resulting through the attachment in a cylinder channel gap, over the entire circumference reaching blanket. This can also extend over the entire effective cylinder length in an advantageous embodiment. In an alternative embodiment, several, z. B. two or three, in o. G. Sense across the entire circumference reaching blankets arranged side by side. It is advantageous in this case, an embodiment, wherein only two (two-page width or three-page width) blankets are arranged side by side, so that a joint with the transfer cylinder 11; 13 dividing half-length symmetry plane coincides. Especially for dry offset applications, especially i. V. m. Newsprint (see below) is an embodiment of advantage, wherein each transfer cylinder 11; 13 is assigned a remotely operable and / or automatic washing device 16. Preferably, this is designed to work with a cloth. Preferably, the transfer cylinder 11; 13 formed without tempering, d. H. he is not in operative connection to a tempering device.

The forme cylinder 12 of the printing unit 08 carries on its periphery one or more printing forms designed for waterless offset printing. Whose outward-facing Surface has as color-repellent, ie no color accepting and thus ultimately non-printing, places z. B. silicone-containing areas, which are interrupted by silicone-free (or silicone-free) so ink receptive and thus printing sites, the latter thus form the printing pattern of the printing form. The print pattern embodying the printed image of the relevant color separation (eg black, yellow, magenta or cyan) is for example a (eg amplitude-modulated) screen resolution of at least 60 lines / cm, advantageously at least 80 lines / cm, preferably between 80 and Based on 160 lines / cm. In this case, the grid can basically be formed by amplitude or frequency modulation (the latter periodically or advantageously stochastically). Advantageously, the printing form, the printed image of the extract on the basis of a z. B. stochastic frequency modulated screening on.

The form cylinder 12; 14 is each temperature-controlled, d. H. as a temperature-controllable component 12; 14 trained. For this purpose, it is preferably connected to a tempering device and formed with permeable by the tempering temperature control fluid. Preferably, the forme cylinder 12; 14 (in contrast to a pure cooling) in the manner formed by the tempering tempered such that a temperature of the forme cylinder 12; 14 through flowing fluid and / or the temperature of the lateral surface and / or located on the cylinder jacket ink in a predeterminable temperature range is adjustable and can be maintained. In a preferred embodiment, at least one control circuit is provided for this purpose. In a further advantageous with respect to a start-up further training includes the temperature control in addition to a temperature control the cooling fluid as needed cooling source also a temperature control the heating of the heating medium, for. B. a Heizfluidkreislauf or a heating unit.

The temperature-controlled forme cylinder 12; 14 has z. B. in the region of one of its end faces (eg operating side) a coaxial rotary feedthrough for the inflow and outflow of the tempering fluid, and in the region of the opposite end face (eg drive side) the rotary positive drive (drive motor 15 and / or a transmission part) on.

In an advantageous embodiment of the form cylinder to be tempered is 12; 14 so formed in terms of its internal structure, so that the cylinder jacket on its effective length for the ink guide in the interior both with flow channels, which lead fluid from the fluid inlet towards the opposite end side flowing fluid, as well as flowing back from the inlet remote end face fluid flow channels in thermal contact stands (countercurrent principle). In this way, a certain balance between the tempering with little and already more heated Temperierfluids takes place in each with respect. Color guide relevant axial section, which effectively sets everywhere a mixing temperature or at least a profile with very low amplitudes.

As in Fig. 2 for the upper double printing unit 17 indicated, is preferably a bearing 35 for at least one of the transfer cylinder 11; 13 is provided which allows the pressure on / off along a linear travel. The adjustment direction along the linear travel forms with one of the two transfer cylinders 11; 13 in pressure-on connecting plane z. B. at most an angle of 15 °, preferably at most 10 °, and therefore acts predominantly to the pressure point 10 toward or away from this. At least both form cylinder 12 are advantageous; 14 and at least one of the two transfer cylinders 11; 13, preferably all four printing cylinder 11; 12; 13; 14 of the double printing unit 17 so adjustably stored. For this purpose, the printing cylinder 11 mounted in this way is; 12; 13; 14 stored in a radial bearing bearing block, which in turn is movably mounted in linear bearings with respect to the direction of adjustment. By this linearly adjustable design of the bearing 35, it is possible, for example, a print substrate dependent Anstelllage, ie, for example, printing gap and / or pressure force to perform without disturbing pivotal movement.

In a particularly advantageous embodiment with respect to printing gap and / or pressure force a with respect to pressure on / off movably mounted printing cylinder 11; 12; 13; 14, in particular at least one of the transfer cylinder 11; 13, by a force-controllable actuator, z. B. a pneumatically or hydraulically actuated actuator, adjustable. With regard to a force controllable means in this context that a pressure to be acted upon selectable, z. B. is selectable from several levels of pressure or is selected or can be entered via an input device. Due to the force-controllable actuator, a pressure in the printing area 10 can be optimally adapted to the paper quality and / or thickness. This is particularly advantageous for printing machines in which either two different qualities, eg. B. in coldset or heatset to be printed. Preferably, at least one such actuator in the above storage 35 at least of the adjustable transfer cylinder 11; 13, preferably in the storage 35 all adjustable printing cylinder 11; 12; 13; 14 provided.

The inking unit 09 is designed as a so-called roller inking unit 09 and has on the input side, ie form cylinder remote, a ink metering system 18, through which the printing ink can be introduced into the inking unit 09 with respect to at least its quantity. In the present inking unit 09, the ink metering system 18 should preferably be in the form of a continuous ink-introducing system, and the inking unit 09 in particular as a film inking unit 09. Between Farbdosiersystem 18 and form cylinder 12; 14 is a roller train provided by which the registered ink "triturated", ie as uniform as possible on the roll circumferences. The color input is not controlled via an anilox roller, in particular the tempering of such an anilox roller, as in the case of a so-called short inking unit, but via the ink metering system 18. The roller inking unit 09 is preferably formed without an anilox roller. In the present inking unit 09, therefore, no ink metering is provided by means of a doctor blade (for example a doctor blade or doctor blade) which is placed on an anilox roller. The control of the color input preferably takes place via the mechanisms typical of a film inking unit 09.

The inking unit 09 provided here has a comparison with a commercial or commercial printing unit comparatively smaller number of rollers or cylinders, z. B. only eight or nine directly in the ink stream arranged rollers or cylinders. In addition, if necessary, one or more so-called. Rider rolls, rider cylinder or take-off rolls occur, which are not arranged in the color flow. Under "in the ink stream" are here rollers or cylinders to understand, which at least one contact point to an upstream, d. H. directly or indirectly to the ink dosing system 18 leading roller (or cylinder), and at least one of the first-mentioned contact point different second contact point to a downstream, d. H. directly or indirectly to the forme cylinder 12; 14 leading roller (or cylinder) has.

These have a positive drive for their traversing movement, which z. B. either by its own drive means, for. As a motor, or via a rotation of the roller 19; 21 can be formed in a traversing movement converting gear. These two as a distribution cylinder 19; 21 formed rollers 19; 21 of the inking unit 09, which is designed in particular as a film inking unit 09, may preferably be parallel (in roller compactor) (FIG. Fig. 3 ) or in an alternative serial ( Fig. 4 ) can be arranged. The printing ink is replaced by at least one roller 22 cooperating with the forme cylinder 12; 23; 24, z. B. inking roller 22; 23; 24, applied. In order to ensure a good inking despite comparatively "shorter" inking 09, act with the forme cylinder 12; 14 in pressure-on advantageous at least two, but preferably three rollers 22; 23; 24 of the inking unit 09 as so-called. Ink application rollers 22; 23; 24 together.

A control circuit in this case therefore comprises at least one sensor S0x (eg S03, S03 ') supplying a temperature measurement value (actual value) at the destination (in the fluid circuit and / or on the roller 19, 21 or of the printing unit cylinder 12, 14) Actual value with a predetermined or predetermined target value for the destination comparing controller or control process (here a example implemented in the control and / or regulating device 49 control process), a component (roller 19, 21 or printing cylinder 12, 14) and one with the component together acting fluid circuit as a controlled system, and at least one on the controlled system, in particular acting on the fluid circuit actuator 51 (69), here z. B. the controllable valve 51 (69), on. In principle, a plurality of measured or actual values can also be included in the process processing and / or multiple actuators (for example a plurality of valves and / or a pumping capacity and / or the activity of a heating medium) acting on the same circuit may be provided by the Regulator or control process to be addressed or be. With "one (same) control loop" is in the local context, an adjustable cycle, z. B. Temperierkreislauf 37 (38) with possibly all its parallel Temperierzweigen 37.y (38.x) to understand, in which or in which via a same adjusting means (valve 51 (69)) tempered fluid flows.

The control and / or regulating device 49 (or the control processes implemented therein) can -. B. from a higher-level machine control or a control center implemented logic - the printing process data, in particular an indication of the target and / or actual speed v _m (machine speed) and / or data for the color type used and / or the affected printing unit 08 or Double printing unit 17 to be supplied or. Based on these data is then with the appropriate memory and / or computing means, the adjusted setpoint temperature T _set (possibly only maximum temperature) for the destination of the control process concerned, ie directly for the material to be tempered component (for example, the form cylinder 12;. 14, or the Roller 19; 21 via preferably a sensor S03; S03 ') or indirectly a fluid temperature at a specific location (of the sensor S0x to be used) of the forme cylinder 12; 14 and the roller 19; 21 tempering fluid circuit determined. This is then z. B. formed depending on the machine speed. The same is the same in the same way to the tempering of a roller 19; 21 via a same tempering temperature control 38 with corresponding fluid, measuring points and actuator (s) 69 to transfer. The means for determining the target temperature T _soll need not be housed structurally in a same objective control and / or regulating device 49, but may also be provided in the control room itself or a machine control. In this case, the setpoint temperatures T _soll (or temperature ranges) of the above-mentioned control and / or regulating device 49 of the respective control circuits (or temperature control circuits 37 (38)) as a target specification of the centrally or decentrally arranged control processes having control and / or regulating device 49 transmitted. A one or more looped particular execution, z. B. a structural or procedural conditions (eg., Runtime and / or manipulated variable limitation real actuators and / or machine speed) execution of the control path, in particular in the manner of a cascade control, of the control process implemented in the control and / or regulating device 49 acts by comparing one or more of the actual temperatures T _ist (to sensor S01, S01 S03, S03 ' etc.) with the respective setpoint temperature T _set (or temperature range) in accordance with their implemented logic on the valve 51 (69), and, if present and, if necessary, a heating device 52 to the desired temperature T _set on the component (plate cylinder 12, 14 and / or roller 19, 21) or at least at the affected destination, z. B. at the relevant temperature measuring point to achieve.

The secondary circuit 37 (38) from the primary circuit 43 (for 38 partly also 59 or 77, see below) zuzuführendes, z. B. colder fluid is for example from a -. B. vertically in the printing tower 01 or on an end face of the printing tower 01 extending - feed line 53 of the relevant primary circuit 43 (for 38 partly also 59 or 77, see below), the thereby deriving from the secondary circuit 37 (38), z. B. heated fluid, for example, a z. B. vertically in the printing tower 01 or on an end face of the printing tower 01 running - return line 54 at a return point 58 of the primary circuit 43 (partly also 59 or 77, see below) is returned (see, eg. Fig. 6 to 16 ). Preferably, the fluid is conveyed in the primary circuit 43 by at least one pump 56 (64), which z. B. in the flow line 53 before a first sampling point 57 (61) is arranged. Between the last removal point 57 (61) and the first return point 58 (62) of the primary circuit 43, a preferably adjustable valve 66 (79), z. As a pressure control valve 66 (79) or a pressure reducer 66 (79) may be provided to ensure a desired pressure gradient between flow and return and adjust if necessary. Especially before or during a restart of the machine, by opening the valve 66 (79), the "warm" fluid present in the lines of the primary circuit 43 (59) can be quickly tempered or exchanged, so that it is not heated by the components 12; 14; 19; 21 must flow.

The temperature control by means of the tempering circuit 37 (38) thus does not take place (or at least not predominantly) via the variation of a volume flow to be led through the component to be tempered (eg roller (s) 19, 21 or printing cylinder 12, 14) via a specific temperature change of the fluid circulating in the temperature control circuit 37 (38) by replacement of a part of the circulating fluid by (eg colder) fluid from the primary circuit (at a substantially constant volume flow in the secondary circuit 37 (38)). Of course, a change in volume flow, z. B. for basic adjustment or adjustments or readjustment required relative pressure levels (see below), but this is not to be understood in the sense understood here of the operational tempering. Operationally, the regulation of the fluid temperature in the secondary circuit 37 (38) takes place via the exchange of circulating fluid at a substantially constant volume flow. The above is also to be read and applied to the reproduced in parentheses as reference numerals components of the above-described parent circuit 59.

The - at least form cylinder 12; 14 tempering secondary circuits 37 supplying - Primary circuit 43 may be formed either as a closed, the pressure tower 01 associated circuit, which optionally arranged in the primary circuit 43 tempering 60, z. B. a cooling source 60, in particular a controllable cooling unit 60, through which the circulating in the primary circuit 43 fluid, for example, to a temperature below ambient temperature is cooled (see, eg. Fig. 5 ). In several provided for a printing tower 01 primary circuits 43 and primary circuit branches 43 and / or independent of the primary circuit 43 temperature of a roller 19; 21 tempering secondary circuit 38 may also be limited to the printing tower 01 superordinate circuit 77, z. Supply circuit 77, which then contains, for example, the temperature control device 58 and feeds the primary circuit 43 or the primary circuits 43 and / or the secondary circuit 38 to be supplied independently (see, for example, below to Fig. 15 ). In this case, the tempering device 39 assigned to the printing tower 01 is autonomous and decentralized by tempering devices 39 of other printing towers 01. The temperature control device 60 can be designed as a commercially available temperature control device with a thermostat which outputs a fluid at the output (possibly via a control device) provides. This tempering device 60 may also include a heating means in an advantageous embodiment, in order - for example, in cold seasons - to be able to heat the temperature of the fluid optionally to the desired temperature.

However, in an advantageous alternative embodiment (see, eg, below to Fig. 16 ) is the primary circuit 43 in conjunction with a plurality of printing towers 01 parent circuit 59, z. B. parent primary circuit 59, from which for the primary circuit 43, z. B. compared to the secondary circuit 37 (38) colder, fluid removed via a sampling point 61 (81) and in which via a return point 62 (82) fluid is fed back from the primary circuit 43. In this case, the primary circuits 43 of the printing towers 01 parallel flowed through "loops" or branches, z. The primary circuit (43; 59) may then be considered to consist of the superordinate circuit 59 and the parallel primary circuit branches 43. In contrast to the interface between secondary circuit 37 (38) and primary circuit branch 43 (59; 77), in the interface between primary circuit branch 43 and primary circuit 59 (77) preferably no separate temperature control takes place via metering by means of a valve, so that the primary circuit branch 43 entering volume flow through the interaction of the pump 56 (64) and pressure conditions is determined.

It is only one -. B. correspondingly larger-sized - tempering 63, z. B. cold source 63, z. B. a controllable refrigeration unit 63, for the temperature of several, possibly all, connected printing towers 01 required (see z. B. below Fig. 16 ). The tempering device 63 may be formed as a commercially available temperature control device with a thermostat, which provides at the output of a fluid (possibly via a control device) vorgebaren target temperature. Due to the possibility of a larger dimensioning, it may also be of particular advantage to form the temperature control device 63 as a device combining two cooling processes, in which, in addition to an example, the working fluid under ambient temperature cooling chiller, z. B. compression refrigeration, also an optional operable and / or optionally switchable free cooler is provided. The tempering device 63 may in an advantageous embodiment also include a heating means to - for example, in cold seasons - the temperature of the fluid z. B. before starting if necessary, to be able to heat to the desired temperature. The parent circuit 59 has a pump 64 through which the fluid is driven in the parent circuit 59. Nevertheless, preferably each connected primary circuit 43 ("primary circuit branch" 43) has its own pump 56. This makes it possible to ensure that the respective primary circuit branches 43 can be operated in each case with suitable pressure despite possibly different effective line resistances. In addition to this own pump 56, the primary circuit branch 43 z. B. also not shown pressure equalization vessel.

Between last removal point 61 (81) and first return point 62 (82) of the higher-level tempering circuit 59 or supply circuit 77 is z. B. a bypass with a preferably adjustable valve 79, z. B. a pressure control valve 79 and a pressure reducer 79, provided to set a desired pressure gradient between flow and return and possibly at a slight decrease by the Primärkreislaufzweige 43 a minimum level of fluid circulation in the parent circuit 59 to ensure (see, eg. Fig. 15 and 16 ).

The pump 56 of the primary circuit branch 43 is preferably with respect. A differential pressure between flow and return, especially between a not shown measuring point in the flow line 53 to the pump 56 and before the first sampling point 57 and not shown a measuring point in the return line 54 after the last return point 58 in the primary circuit 43 and primary circuit branch 43 and before the return point 62 into the parent circuit 59, regulated operated or run so operable together with said measuring points. Preferably, it is or a control module associated with it to a desired differential pressure, z. B. a lying between 1 and 3 bar differential pressure, in particular a differential pressure of 1.8 to 2.3 bar, set. Change the line resistance, z. B. by changing withdrawal flows into the secondary circuits 37 (38) or by changing the setting of the valve 66, so the appropriate differential pressure level between flow and return is still maintained. This ensures that the conditions when metering into the secondary circuit 37 (38) or the secondary circuits 37 (38) are always constant and thus a better calculable control process can take place.

As stated above, the form cylinder 12; 14 of the printing tower 01 each individually or in pairs per double printing unit 17 with independently temperature-controlled temperature control circuits 37 in thermal interaction. As also mentioned above, each printing unit 08 is at least one roller 19; 21, advantageously at least one distribution cylinder 19; 21, but preferably two or both distribution cylinders 19; 21 each printing unit 08 tempered formed and are available with a tempering circuit 37; 38 in thermal interaction. To the temperature, in particular to the dynamics of required temperature changes as well as to the accuracy in maintaining a temperature (larger temperature window), the roller (s) 19; 21; 22; 23; 24/29; 26; 27; 28 are set much lower requirements here, as in the temperature of the forme cylinder 12; 14. Using the above for independent temperability of cylinders 12; 14, for tempering the roller (s) 19; 21; 22; 23; 24/29; 26; 27; 28 as well as the exemplary embodiment of possible temperature control circuits 37 (38), advantageous embodiments are set out below: In Fig. 6 . 8th . 10 . 12 and 14 be the two form cylinder 12; 14 tempered each double printing unit 17 by a common tempering circuit 37 (regardless of the other double printing units 17). In principle, the form cylinder 12; 14 may also be passed through in series, but is preferably a parallel, particularly advantageous with respect. The sections as symmetrical as possible or with respect to line resistance similar, fluid management in two parallel Temperierzweigen 37.1; 37.2 (also commonly referred to as 37.y in the text). In the interior of the secondary circuit 37 circulates the tempering fluid, funded by the pump 47. The respective temperature control circuit 37 (secondary circuit 37) is connected via an extraction point 57 and a return point 58 to the primary circuit (branch) 43. If a setpoint temperature T _soll (or maximum temperature) is exceeded at a above-mentioned, not shown here sensor S0x (for at least the Formzylindertemperierung preferably on a sensor S03 or S03 '), then colder fluid from the primary circuit (branch) 43 via the valve 51 introduced into the secondary circuit 37 (38) and the corresponding amount via the return point 58 in the primary circuit (branch) 43 discharged. Per pair of forming cylinders 12; 14, a temperature control circuit 37 (38) connected to the primary circuit (branch) 43 is provided here.

In a technically less complex solution of the Fig. 6 are also to be tempered rollers 19; 21 with the two form cylinder 12; 14 tempering secondary circuit 37 in thermal interaction. In an advantageous embodiment, in each of the tempering 37.y each downstream of the forme cylinder 12; 14 two the same printing unit 08 associated distribution cylinder 19; 21 parallel or serially flowed through. The temperature of the distribution cylinder 19; 21 moves here in a wide temperature window, depending on the for the forme cylinder 12; 14 set temperature and the heating of the fluid in this. In this case, it may be advantageous in terms of the temperature gradient to be set, if in the execution of the inking unit 09 after Fig. 4 first of all, the mold cylinder nearer (19), and then the Formzylinderfernere (21) flow cylinder is flowed through. In case of execution after Fig. 3 For example, in the circumferential direction first distribution cylinder 19 may be flowed through first. In principle, however, if necessary, the reverse order may be provided. Preferably, however, it is provided that the two branches of the secondary circuit 37 again have similar routes in terms of line resistance. For the four double printing units 17, the temperature in Fig. 6 representatively shown only on the upper double printing unit 17.

In the execution according to Fig. 8 is contrary to Fig. 6 for the temperature of the four rollers 19; 21 each double printing unit 17 a different from the temperature control 37 Temperierkreislauf 38, in particular secondary circuit 38, is provided. The same applies to the temperature control circuit 37 set forth above, but with the following reference symbols: feed point 67, pump 68 and valve 69 instead of feed point 46, pump 47 and valve 51. For one or more measuring points or one or more sensors S0x in the secondary circuit 38 tempering control loop that applies to the temperature control 37 applies. Possibly. However, the requirement is considerably lower, so that only a single sensor S0x in the secondary circuit 38 or on one of the rollers 19; 21 can be sufficient. The rollers 19; 21 tempering secondary circuits 38 are in the embodiment according to Fig. 8 also connected via withdrawal points 57 and return points 58 to the primary circuit (branch) 43.

In contrast to Fig. 8 stand in the execution Fig. 10 the rollers 19 to be tempered; 21 of two superimposed double printing units 17 with a same secondary circuit 38, so only a corresponding control circuit or a same tempered fluid, in thermal interaction. Although other flow patterns may be chosen here, but preferably as symmetrical as possible fluid guide z. B. via appropriately trained parallel Temperierzweige 38.1; 38.2; 38.11; 38.12; 38.21; 38.22 provide, here z. B. the two rollers 19; 21 of the same printing unit 08 again each serially, for example in the above order, be flowed through. The not fully shown temperature of the two lower double printing units 17 is carried out in the same way. In the Fig. 11 Secondary circuits 38 are fed here from the secondary circuits 37 feeding primary circuit (branch) 43 fed.

In the execution after Fig. 12 is for the rollers to be tempered 19; 21 of the printing tower 01 only one control loop or a tempering circuit 37 is provided. Again, in an advantageous embodiment, a substantially symmetrical fluid guide with each branch of two serially traversed rollers 19; 21 provided in approximately equal lengths. The in Fig. 12 set secondary circuit 38 is fed here from the secondary circuits 37 feeding primary circuit (branch) 43. In this case, preferably (not shown) is a removal point for the temperature control circuit 38 either before the first or after the last removal point 57 of the forme cylinder 12; Provide 14 tempering Temperierkreisläufe 37.

Fig. 14 shows an embodiment of the temperature of the printing tower 01, wherein the temperature of the forme cylinder 12; 14 as described individually (not shown in FIG Fig. 14 ) or in pairs by secondary circuits 37, which in turn are supplied by at least one primary circuit (branch) 43. In an advantageous embodiment according to Fig. 14 is the rollers 19; 21 tempering secondary circuit 38 (or at several, the secondary circuits 38) are not from the one or the secondary circuits 37 of the forme cylinder 12; 14 tempering primary circuit (branch) 37 fed, but will (or be) either by its own, in Fig. 14 indicated in the tempering circuit 38 indicated or by its own the tempering 38 in a separate primary circuit upstream and only by reference numeral "45" indicated temperature control 45, z. As cold source, in particular a controllable refrigeration unit, tempered or supplied by a higher-level tempering circuit 59 forth as needed. In Fig. 14 this is schematically for only one tempering circuit 38 for all to be tempered distribution cylinder 19; 21 of the Pressure tower 01 shown, said temperature control circuit 38 a plurality of parallel Temperierzweige 38.1; 38.2; 38.3; 38.4 (eg 38.x), in which parallel one or more flow in serial flow cylinder 19; 21 are tempered. The tempering circuit 38 has the pump 68 which the fluid via a -. B. vertically in the printing tower 01 or on an end face of the printing tower 01 extending - flow line 71, via sampling points 74 through the or more Temperierzweige 38.x, return points 76, a -. B. vertically in the printing tower 01 or on an end face of the printing tower 01 extending - return line 72 and a bypass line 73 circulates. In unillustrated, closed design is provided in the temperature control 38, in particular between the last return point 76 and the first extraction point 74, a non-illustrated above-mentioned cold source. Instead of a separate cooling source, however, the temperature control circuit 38 is preferably (for example via a valve 69) described in the above-mentioned example for the temperature control circuit 37, and / or a removal point 81 is assigned to the pressure tower 01 (see, for example, US Pat. Fig. 15 , Execution b) and c) parent circuit 77, z. B. supply circuit 77, or connected to a plurality of printing towers 01 associated higher temperature control circuit 59. The tempering circuit 38 then has the feed point 67, at which from a flow of a parent circuit 59 (77) via z. B. the controllable valve 69 colder fluid can be fed, and via a corresponding line fluid from the temperature control circuit 38 in a return line of the parent circuit 59 (77) is traceable. The rollers 19; 21 (or distribution cylinder 19, 21) tempering Temperierkreislauf 38 (secondary circuit 38) is then again associated with a pump 68, a valve 69 and a feed point 67. The control circuit associated with the temperature control circuit 38 comprises, in addition to the valve 69 as an actuating element 69, at least one sensor S0x, by means of which an actual temperature T _{ist of} the fluid and / or the roller (s) 19; 21 determined in the above manner and in the control and / or regulating device 49 with a setpoint temperature T _soll (preferably a permissible temperature range) is compared. It may be in Temperierkreislauf 38, if necessary, only a sensor S0x, z. B. in the flow line 71 or the return line 72 may be provided. It can also each in the flow line 71 and the return line 72 each a sensor S02; S04 be provided which z. B. in the manner of the above-mentioned virtual sensor S03 'work together. Preferably, however, each of the Temperierzweige 38.1; 38.2; 38.3; 38.4 (at least Temperierzweige first order or main branches) associated with a sensor S0x for determining a respective actual temperature, wherein z. B. in the control and / or regulating device 49, the actual temperatures of all Temperierzweige 38.1; 38.2; 38.3; 38.4 be checked for affiliation to the permissible temperature range. If one of the temperatures falls above the upper limit of the range, colder fluid is metered in via the valve 69 in the manner described above or a cold source (not shown) is activated. The higher-order temperature control circuit 59 (77) serving as the fluid source can preferably be the same, which also feeds the primary circuit 43 of the mold cylinder temperature control units. In an advantageous development, for the case of n (n ∈ N), tempering branches 38.1; 38.2; 38.3; 38.4 (38.x) in at least (n-1) tempering branches 38.1; 38.2; 38.3; 38.4 with respect to the flow resistance and / or cross-section adjustable valves 78 provided by which a basic setting of the relative flow rates (to compensate, if necessary, due to differences in line resistances differences) in the branches feasible and can be changed if necessary. These valves 78 can manually or even -. B. forth from a control room or console computer - remote actuated adjustable. However, said adjustability of the relative flow rates is not comparable to a cooling regulated by the flow of tempering fluid, but merely supplements a temperature control controlled by fluid exchange (at a substantially constant volume flow) in the case of parallel branches of a same temperature control circuit 37; If, by regulation of the fluid temperature of the temperature control circuit 38 encompassing all or all pressure units 08, the condition relating to the affiliation of all branches to the permitted temperature range can not be fulfilled, then by changing the cross section at one or more of the valves 78 a " Redistribution "of the fluid flow, and thus an adjustment of the temperature of the connected to the common temperature control circuit 38 rollers 19; 21 possible. These are the adjustable relative flows (eg via valves 78), in Fig. 14 illustrated embodiment is on all versions of temperature control circuits 37; Apply 38 described above and to transmit analogously, in which a tempering circuit 37; 38 or a branch of a tempering circuit 37; 38 in parallel branches, z. B. in Temperierzweige 38.x or in exemplary in Fig. 6 named tempering branches 37.1; 37.1 (37.y) shares. This also applies, for example, to in Fig. 6 and 8 to 13 explained routing in several form cylinder 12; 14 or more rollers 19; 21 parallel temperature control circuits 37; 38. Here too, at least (n-1) of n branches of a same temperature control circuit 37; 38 have a respect to the cross-section or flow adjustable valve 78. The same applies to the division of the primary primary circuit 59 in the primary circuit branches 43, where also in the case of n branches at least in (n-1) branched circuits a corresponding valve may be provided.

The example of the according Fig. 14 only one tempering circuit 38 for all distribution cylinders 19; 21 of the printing tower 01 having principle of the "form cylinder primary circuit (-zweig)" independent Walzentemperierung is advantageous to the versions individually temperable form cylinder 12; 14 and / or to transfer to versions in which z. B. for the temperature of the distribution cylinder 19; 21 of the printing tower 01 two or more such, independent of the primary circuit 43 temperature control circuits 38 are provided. Deviating from the example of Fig. 14 can also be formed in other ways, serially traversed groups of Reibzylindern 19; 21 may be formed or it may instead of the serial pass as shown also more parallel, z. B. only one or two rollers 19; 21 tempering Temperierzweige 38.1; 38.2; 38.3; 38.4 or less tempering branches 38.1; 38.2; 38.3; 38.4, but with more tempering branches 38.11; 38.12; 38.21; 38.22 (reference numeral "Temperierunterzweige" exemplarily in Fig. 10 and 14 ) and / or further divided branches of Temperierunterzweigen 38.11; 38.12; 38.21; 38.22 be provided. Such Temperierunterzweige 38.11; 38.12; 38.21; 38.22 and possibly further subdivided Temperierunterzweige should, however, if not explicitly excluded, equally under the name "Temperierzweige" be taken.

As in Fig. 15 and 16 illustrated by way of example, Temperierzweige 38.1; 38.2; 38.3; 38.4 also depart from a flow distributor 83 and open in a return collector 84.

In Fig. 15 and 16 By way of example, three variants for printing tower temperature control (labeled a, b and c) are shown side by side and in the case of Fig. 16 connected to a common parent circuit 59. Although in the case of several, z. B. two or three in a section of juxtaposed printing towers 01 preferably each have a same variant is used, could possibly also be different at the same time the different variants for different printing towers 01 of the section are used.

For the mentioned versions of the FIGS. 6 to 14 , in particular the Fig. 6 . 8th . 10 . 12 and 14 , the two rollers 19; 21 per printing unit 08 basically always be flowed through in parallel instead of serially as needed.

In the remarks of the Fig. 6 . 8th . 10 . 12 and 14 are the two form cylinder 12; 14 and / or the roller pairs of the two printing units 08 of the same double printing unit 17 each to common secondary circuits 37; 38 tethered. At the same time, with little effort, it is basically possible to optimally adapt the different colors to the currently used substrate (paper).

As mentioned above, however, it may be advantageous in terms of fine tunings between perfecting side when the two forme cylinder 12; 14 of the double printing unit 17 and / or the rollers 19; 21 of the two printing units 08 of the double printing unit 17 by mutually different Temperierkreisläufe 37; 38 are tempered.

In Fig. 7 . 9 . 11 and 13 be the two form cylinder 12; 14 each double printing unit 17 tempered by each independently thermostatic temperature control circuits 37 (regardless of the other printing units 08). Inside each secondary circuit 37 circulates the tempering fluid, funded by the pump 47. The respective temperature control circuit 37 (secondary circuit 37) is connected to a primary circuit (branch) 43 via a sampling point 57 and a return point 58. In general, a common, substantially vertically extending primary circuit (branch) 43 can be used for the temperature control circuits 37; 38 may be provided. Also for reasons of clarity, however, an embodiment with two primary circuits 43 is shown, which is possibly advantageous in terms of divisibility and / or fluid paths, wherein two z. B. substantially vertically extending primary circuits 43 are provided in the printing tower 01, which in each case the forme cylinder 12; 14 of a web page or a printing tower half (a divisible printing tower 01) tempered secondary circuits 37 supplied. The temperature control by means of the temperature control circuits 37; 38 or control loops, however, takes place in the same way. Is a desired temperature T _set (or maximum temperature or range) for a destination on a not shown sensor S0x (see above) is exceeded, cooler via the valve 51 fluid from the primary circuit (branch) 43 in the secondary circuit 37 (38) introduced and the corresponding amount via the return point 58 in the primary circuit (branch) 43 discharged. Per form cylinders 12; 14 here is a with the primary circuit (branch) 43 and one of the primary circuit (branches) 43 connected tempering circuit 37 is provided.

In a technically less complex solution of the Fig. 7 are also to be tempered rollers 19; 21 with the same printing unit 08 associated with the form cylinder 12; 14 tempering secondary circuit 37 in thermal Interaction. In an advantageous embodiment, each downstream of the forme cylinder 12; 14 two the same printing unit 08 associated distribution cylinder 19; 21 be flowed through serially. As mentioned above, it can be advantageous in terms of the temperature gradient to be set if in the embodiment of the inking unit 09 Fig. 4 first of the form cylinder nearer (19), and then the form cylinder remoter (21) flow cylinder is flowed through. In case of execution after Fig. 3 For example, the first in the circumferential direction of the distribution cylinder 19 may be flowed through first. Basically, however, if necessary, the reverse order may be provided here. For the four double printing units 17, the temperature in Fig. 7 representatively shown only on the upper double printing unit 17.

In the execution according to Fig. 9 is contrary to Fig. 7 for the temperature of the two rollers 19; 21 each printing unit 08 a different from the tempering circuit 37 tempering 38, in particular secondary circuit 38, is provided. In principle, however, can also in accordance with the rolling tempering of not shown here variant Fig. 8 the four rollers 19; 21 each double printing unit 17 by a common secondary circuit 38, be tempered. On the rollers 19; 21 tempering Temperierkreislauf 38 is again the above set up for tempering 37 in the same way, but using the reference numbers for the feed point 67, the pump 68 and the valve 69 apply. The rollers 19; 21 individual printing units 08 tempering secondary circuits 38 are in the embodiment according to Fig. 9 also via withdrawal points 57 and return points 58 to the primary circuit (branch) 43 and possibly with the primary circuit (branches) 43 connected.

In contrast to Fig. 9 stand in the execution Fig. 11 the rollers 19 to be tempered; 21, in particular distribution cylinder 19; 21, two superimposed printing units 08 with a same secondary circuit 38, so only a corresponding control circuit, in thermal interaction. Although other flow patterns may be selected here, but preferably one is possible provide symmetrical fluid guide, in which case z. B. the two rollers 19; 21 of the same printing unit 08 again each serially, for example, in the above order, are traversed. The not fully shown temperature of the two lower double printing units 17 is carried out in the same way.

In the execution after Fig. 13 is for the rollers to be tempered 19; 21, in particular distribution cylinder 19; 21, the left and the right printing units 08 of the printing tower 01 each provided only a control loop or a temperature control 38. Again, in an advantageous embodiment, a substantially symmetrical fluid guide, ie for each of two serially traversed rollers 19; 21 containing branches provided a roughly equal length of track.

For reasons of clarity, the figurative depiction of the Fig. 14 parallel training with individually temperable cylinders 12; 14 and / or two Temperierkreiszweigen 43 is omitted. Based on the execution of the roller temperature control Fig. 14 with a separate source of cold or own connection to a higher-level tempering circuit 59 (77), this variant of the Fig. 14 also on individually temperature-controlled forme cylinder 12; 14 and / or to the embodiment with two primary circuit branches 43 according to z. B. the Formzylindertemperierung Fig. 13 be transmitted in the same way. Here, a primary circuit branch 43 or it can as in Fig. 13 2 shows two primary circuit branches 43 (for example on each side of the web) for supplying the forme cylinders 12; Be provided 14 tempering temperature control 37. To this one primary circuit branch 43 or to these two primary circuit branches 43 can then as in Fig. 14 one the rollers 19; 21 of the printing tower 01, possibly via Temperierzweige 38.x, tempering secondary circuit 38, or it can, for. B. two such rollers 19; 21 of the printing tower 01, possibly via Temperierzweige 38.x, tempering secondary circuits 38, z. B. per web page a secondary circuit 38 may be provided. In an advantageous in terms of short distances sections and / or simpler piping design z. B. one each the rollers 19; 21 tempering tempering circuit 38 and one for the supply of the forme cylinder 12; Provided 14 tempering temperature control 37 serving primary circuit branch 43.

Also for the mentioned embodiments of Fig. 7 . 9 . 11 and 13 as well as the corresponding variant of the Fig. 14 the two rollers 19; 21 per printing unit 08 in principle also be flowed through parallel instead of serial as needed.

The solutions according to Fig. 6 and 7 do not require additional control circuits or temperature control circuits for the tempering of the rollers 19; 21, in particular the distribution cylinder 19; 21. With a suitable design of the ink and / or setting of the target temperature T _{soll of} the respective temperature control 37, the from the forme cylinder 12; 14 independent temperature of the distribution cylinder 19; 21 omitted. This also generally applies to the above-mentioned preferred embodiment of the transfer cylinder 11; 13 without the requirement of its own tempering.

The solutions according to Fig. 8 and 9 (or a combination of individually tempered forme cylinder 12, 14 with "double-printing-system" temperature control of the rollers 19, 21 to be tempered) have an increased technical complexity through a total of eight, twelve or sixteen temperature control circuits 37; 38 or corresponding control circuits, however, allow a high degree of adaptation of the color properties to the present in the printing tower 01 needs each other subsequent pressure points 10 and / or paper properties.

The solutions 10 to 14 is z. B. together that rollers 19; 21, in particular distribution cylinder 19; 21 of several, at least several (preferably all) printing on a same side of a web 02, printing units 08 of a printing tower 01 by a common temperature control circuit 38 and a control circuit that they are jointly formed tempered, resulting in significant savings Temperierkreisläufen 37 or control circuits brings with it, while the forme cylinder 12; 14, in particular preferably the forme cylinder 12; 14 all printing on a same side of the web 02 printing units 08, are tempered by respective independent temperature control circuits 37 with appropriate control circuits. In the remarks of the Fig. 14 is also the the distribution cylinder 19; 21 tempering circuit 38 regardless of the form cylinder 12; 14 tempering circuits 37 and of the primary circuit branch (s) 43 tempered by its own cooling source or its own connection to a higher-level tempering circuit 59. As a result, for example, the possibility of a direct, individual adjustment of the desired temperature level in which the rollers 19; 21 temperature control circuit 38 (or in the rollers 19, 21 Temperierkreisläufen 38) allows, without a possibly fluctuating load of the temperature control circuits 37 supplying primary circuit branch 43 takes place. The less critical tempering of the rollers 19; 21 (larger allowable temperature range and / or lower demand on the dynamics) is in this case of the within narrow limits and / or more stringent requirements for the dynamics underlying temperature of the forme cylinder 12; 14 separated.

The stated embodiments are also applicable to embodiments in which only one of the rollers 19; 21; 22; 23; 24/29; 26; 27; 28, z. B. one of the distribution cylinder 19; 21, and / or a color reservoir 25, or z. B. in addition to one or both Reibzylindern 19; 21, the film roller 27 and / or the ink reservoir 25, or z. B. in addition to one or both Reibzylindern 19; 21, the ductor roller 28 in z. B. several of the described temperature control circuits 38 is included. This could then z. B. the film roller 27 and / or the ductor roller 28 and / or the ink reservoir 25 in addition to one or two Reibzylindern 19; 21 in the relevant temperature control circuit 38 serially / and be integrated in parallel.

However, the film rollers 27 and / or ductor rollers 28 and / or ink reservoirs 25 may be additionally tempered by not shown own tempering, which z. B. in the manner of the above-mentioned temperature control circuits 38 may be formed. The embodiments described for the tempering circuits 38 are to be transferred to designs of another such tempering circuit, where each printing unit 08 by the further tempering at least two of the components of film roller 27 and / or ductor roller 28 and / or ink reservoir 25 (eg tempering are. If only the film roller 27 or the ductor roller 28 or the inking unit 25 is to be tempered, then the variants set forth for the tempering circuits 38 are to be transferred in such a way that no second components are serial in the branch or sub-branch concerned, but only one component, namely the film roller 27 or the ductor roller 28 or the reservoir 25 is tempered. If the film roller 27 or the ductor roller 28 is to be tempered, then this is corresponding to that for the distribution cylinder 19; 21 designed tempered trained. If the ink reservoir 25 is to be heated, this can be done, for example, by contacting the line of the temperature control circuit itself with the ink or else by contacting this line with a housing receiving the ink.

In principle, the feed points 46 (67) and pumps 47 (68) of the tempering device 39 of a printing tower 01, contrary to the representations, can also be centrally located, for B. summarized in a so-called. Temperature control, be arranged in a lower area or even in a plane below the pressure tower 01, in which case, however, the conduction paths of the secondary circuits 37; 38 extend accordingly (and sometimes have a considerably different length). As can be seen in the figures, it is advantageous (for example with regard to reaction time and / or symmetrical conditions) for at least the forme cylinders 12 to be advantageous; 14 tempering temperature control circuits 37 (possibly also for the rollers 19, 21) at least each of the feed point 46 (67) and pump 47 (68) of the temperature control circuits 37, z. B. as part of an assembly, at different heights of the printing tower 01, in particular one above the other, so z. B. each close to the component to be tempered component 12; 14 (19; 21). Preferably, these assemblies are located approximately at the height of the printing units 08, the through this assembly too tempering components 12; 14 (19; 21). This can also - especially for the designs Fig. 8 . 10 , possibly 12 and possibly 13 corresponding to the rollers 19; 21 tempering secondary circuits 38 applied. For the execution according to Fig. 12 . 13 and in particular 14 and the related modification, it may be advantageous, the feed point (s) 67 for the rollers 19; Provide 21 tempering secondary circuit 38 in the lower region of the printing tower 01.

The feed points 46 (67) and pumps 47 (68), z. B. each as part of an assembly, are preferably the front side of the printing tower 01 (ie on a front side of the printing unit cylinder 11, 12, 13, 14, for example, on the side frame or connected to the latter frame part, in particular within a frontal, z Arranged supply lines and, where appropriate, ancillary units, space, for example, as a front-end control cabinet (eg, including supply and / or switchgear and mechanical containing called) arranged.This arrangement of the modules integrated in or on the side frame allows the printer-near arrangement each In the case of centrally divisible printing towers 01, the front-side space accommodating the assemblies may possibly be designed as a space that is open towards the center or as two spaces separated at least partially towards the center.

Not only but especially in the case of a separable trained printing tower 01, in which z. B. for the left printing units 08 a left primary circuit branch 43 and for the right printing units 08 a right primary circuit branch 43, each with the corresponding flow or return lines 53; 54 is provided, can on the conduction path between the flow and return lines 53; 54 of the movable part of a separable printing tower 01 and the respective withdrawal or return point 61; 62 from the parent circuit 59 flexible pipe sections, z. B. pieces of tubing, may be provided.

In a development, it may be advantageous if associated with a particular printing tower 01 aggregates of the primary circuit 43 -. B. the pump (s) 56 and possibly provided pressure equalization vessels - and / or one at least the rollers 19; 21 of a printing tower half jointly supplying secondary circuit 38 -. B. its pump 68 and possibly also provided pressure equalization vessel and / or the valve 69 - in a plane below a ground plane, d. H. below the main operating level, and / or in a plane below the foot of the printing tower 01, z. B. in the example coverable recess are arranged. In the case of a pressure tower 01 set up in a table arrangement, that is to say on a gallery level, the recess is also designed, for example, as a recess below the level or step level of the operating personnel in the foot frame or as a recess arranged in the gallery frame. If such a depression or pit is advantageously designed to be coverable, then it is accessible, but not disturbing spatially for the operation of the machine from the front side. With this measure of sunk arranged aggregates the line lengths are shortened, while the frontal accessibility is guaranteed to the instrument room. For several printing towers 01 then z. B. all printing towers 01 such an end-face, in particular coverable depression, in which the fluid in the respective primary circuit branch 46 and / or secondary circuit 38 promotional pump 56 (68), and the junctions between parent primary circuit 59 and the corresponding primary circuit branch 43 (or. Secondary circuit 38) of the respective printing tower 01 are arranged.

The "architecture" of the described tempering device 39 is thus effective and where necessary sufficiently responsive trained by z. B. a parent circuit 59 (substantially predominantly horizontally between the towers 01 running) leads to a cooled below the ambient fluid fluid at the respective towers 01 each fluid removed from the parent circuit 59 and in a (substantially vertically through the or. at the printing towers 01 extending) primary circuit branch 43 and possibly rollers 19; 21 tempering secondary circuit 38 rotates, wherein z. B. Entnahmestellen 57 from the primary circuit branch 43 for the secondary circuits to be tempered 37 (38) and their essential aggregates (eg., Pump 47 (68) and metering valve 51 (69)) as close to the component, ie in the printing tower 01 distributed to different heights, are arranged. Preferably, in this case, it is provided for the less sensitive roller temperature control with respect to the temperature that rollers 19; 21 of a plurality of printing units 08, in particular at least of printing units 08 of a printing tower half or even the printing units 08 of the entire printing tower 01, tempered by a common control circuit or tempering circuit 38 or tempered

As already mentioned above, the secondary circuits 37; 38 with their fluid paths, valves and sensors each part of individual control loops, with a control loop z. B. the component 12; 14; 19; 21 tempering tempering fluid, at least one the temperature of the fluid and / or preferably of the thereby to be tempered component 12; 14; 19; 21 monitoring sensor S0x, at least one actuator 51; 69 (52) and one on the actuator 51; 69 acting rule process includes.

The individual secondary circuits 37; 38 or the correlating control circuits are preferably each own control processes with respect to the measured actual temperature (s) T _ist and setpoint temperatures T _soll assigned. Under control process should generally be understood here a controller which analog, digital or as a software routine z. B. works according to a specific circuit and / or software-based control algorithm. One or more of these control processes may be provided or combined in a common control and / or regulating device 49.

Each of the control processes are individually assigned target temperatures T _soll or assigned and / or predefinable, but basically for several control processes same values can be assigned. As already mentioned above, these predefinable or predetermined temperature specifications generally denoted as setpoint temperatures T _soll may be indicated as temperature _maximum values T _max , as specific setpoint temperature values T _s , if necessary defining a tolerance range T _s ± Δ, or as temperature ranges ΔT _s or . become. The specification of a setpoint temperature value T _s with tolerance range T _s ± Δ and the specification of a temperature range ΔT _s can be treated in the following - where no explicit distinction is made explicitly - whereby the range from said value taking into account the specified tolerances, and vice versa from the specified range a mean target temperature T _soll with symmetrical tolerance range Δ results. Unless otherwise explicitly stated below, the specification of a "setpoint temperature T _soll " is to be understood as meaning the setpoint temperature value T _s (irrespective of any additional tolerances) or the mean value, also center of gravity, of a temperature range ΔT _s .

The control processes of the form cylinder 12; 14 tempering Temperierkreisläufen 37 are preferably tolerance ranges .DELTA. Setpoint temperature values T _s and temperature ranges .DELTA.T _s predetermined, which has a width of z. B. maximum of 3 ° C, advantageously not more than 2 ° C, in particular not more than 1 ° C. In contrast, the control process or are the control processes of the or the rollers 19; 21 of the inking 09 tempering temperature control circuits 38 either only given maximum temperature values, or preferably tolerance ranges Δ and temperature ranges .DELTA.T _s , which -. B. depending on the version above variants - a width of z. B. more than 2 ° C, advantageously more than 3 ° C, and / or a width of z. B. up to 5 ° C, advantageously even up to 7 ° C, map.

At the same time, the condition that during the formation of separate temperature control circuits 37; 38 for printing cylinder 12; 14 on the one hand and rollers 19; 21 on the other hand, the control process of the forme cylinder 12; 14 of a printing unit 08 (individually or together with another forme cylinder) tempering Temperierkreislaufs 37 a smaller allowable temperature range is specified or stored as the control process of the rollers 19; 21 of the associated inking unit 09 (individually or together with rollers of other inking units) tempering Temperierkreislaufs 38. This applies z. B. for each printing unit 08 of the printing tower 01.

In particular for embodiments of the rollers 19; 21 several, possibly one half or even all arranged in the printing tower 01 printing 08 tempering Temperierkreislaufs 38 (possibly with the formation of tempering (under) branches 38.x) can thereby be ensured at low cost yet trouble-free operation. The "distance" with respect to the ink path to the forme cylinder 12; 14 and even to the printing location 10 (i.e., to the printing material), it is possible here, especially when using a "good-natured" printing ink, i. H. a printing ink with rheological color properties, which are not inferior in the relevant temperature range to grand grandients (see below) - a good compromise between procedural effort and achievable print quality in a robust operation - especially when using newsprint. An optionally obstructing this compromise anilox roller with appropriate color flow control over exact temperature specifications is not in the execution of the present newspaper printing press or the printing tower 01 with roller inking system. The choice of an advantageous printing ink and / or an advantageous predetermined temperature range for the rollers 19; 21 tempering control loop and / or possibly an advantageous flow order serial to be traversed rollers 19; 21 can already an advantageous temperature of the forme cylinder 12; 14 come to meet.

An individual and close adaptation of the color property of the optimal, especially sound-free ink application to the printing form, in particular without the possibility of control by a dampening unit, as well as an anticipatory adaptation to the particular possible rupffree interaction of the transfer cylinder 11; 13 with the substrate is by the single or at least pairwise control option the form cylinder 12; 14 given. When setting an advantageous temperature on the forme cylinder 12; 14 (see below) can be adapted to its own temperature of the transfer cylinder 11; 13 be waived. The temperature control circuits 37 of the forme cylinder 12; 14 regulating control circuits preferably access at least one measured value of at least one sensor S02; S03; S03 ';S04; S05 back, the component near the fluid fluid between pump 47 and Formzylindereinritt or advantageously a temperature of the forme cylinder 12; 14 or its surface (sensor S03 or S03 ') detected. In an advantageous development, in order to reduce overshoots, additionally one of the feed point 46 close to the temperature (eg sensor S01) can additionally be determined and taken into account with regard to the dynamics of the regulation process. Although in a very simple, but with respect to the mold cylinder temperature less accurate execution, only the feed-point near sensor S01 could be provided. In the case of a temperature value for which the regulation is based, only one sensor close to the feed point and / or close to the component S01; S02 can the temperature determined here - for example, in o. G i. V. m. Sensor S03 'mentioned manner according to empirically normalized or calibrated and modeled - give information about the mold cylinder temperature. In this case, the temperature specified in the control process in a variant z. B. to the temperature at the considered measuring point as the target temperature. For an advantageous case, however, that an above-mentioned empirical relationship and / or model is stored in the control process and is taken into account by the algorithm, the virtual component or jacket temperature resulting from the modeling can be used as the temperature at the destination as the "measured" temperature then processed by the control process with the target temperature for the same destination, namely on the component or component jacket. This principle is to be applied in particular also for the use of the above-mentioned virtual sensor S03 '. Here too, will then by the relevant control process, the "virtual component or jacket temperature than the actual temperature T _is at the destination" components "or" used mantle surface "and with the predetermined destination for this nominal temperature T _nom processed and evaluated.

This principle is basically to apply to all control circuits or secondary circuits mentioned above, unless the component or jacket temperature is not - as preferred - directly by a sensor S03, z. B. IR sensor, measured, but is determined indirectly via a fluid temperature via a model, but preferably a default setpoint temperature directly for the component or its lateral surface as the destination should be made.

If in the following a target or actual temperature on the component or its lateral surface is mentioned as the target location, then - unless explicitly stated otherwise - it is actually effected on the forme cylinder 12; 14 or on the roller 19; 21 or in particular its lateral surface to be set and / or measurable temperature go out. For the control process, in the case of a "virtual" actual temperature T _ist (eg from S01, S02 or S03 ') to be determined via a fluid temperature, a possible deviation between actual and virtual actual temperature T _{ist is} kept negligibly small via the corresponding modeling and calibration and / or a systematic error possibly even when setting the temperature value T _soll according to z. B. as T ' _{should be} considered.

In embodiments, wherein two parallel form cylinder 12; 14 tempered by a same temperature control 37, each can be a forme cylinder 12; 14 supplying tempering branch 37.1; 37.2 a sensor S02; S03; S03 '; S04 close to the component in the tempering branch 37.1; 37.2 (eg sensor S02 or S04) and / or on the forme cylinder 12; 14 (eg, sensor S03; S03 '(S02; S04)), in which the temperatures of the two temperature control branches 37.1, 37.2, and forme cylinders 12, 14 can _be monitored in parallel for membership of the permitted setpoint temperature T setpoint (range or tolerance) and, if necessary, the temperature of the fluid may be changed by the control process via the actuator 51. Should a difference between the two branches be once so great that the requirement for both forme cylinders 12, 14 is not simultaneous can be satisfactorily, it can be adjusted or newly adjusted via above adjustable valves 78, a relative flow rate, and thus within certain limits, a tempering effect:

In the case of embodiments, wherein by the one or two forme cylinder 12; 14 tempering tempering 37 (37.1; 37.2) and one or more rollers 19; 21 can be tempered or, in addition to one or more of the o. G. Sensors S01; S02; S03; S03 'or measured values to be provided a further sensor, which, for. B. the sensor S02 according to the fluid path before entering the (first) roller 19; 21 or z. B. the sensor S03 or S03 'according to the temperature of the roller surface is arranged descriptive. Instead or advantageously in addition thereto, in a sensor between leaving the (last) roller 19; 21 and be provided before reaching the feed point 46. This can, on the one hand, provide control of the power absorbed and / or an upper estimate of a roller temperature and / or, on the other hand, provide early information on possibly colder fluid to be supplied for the control process.

In the case of one or more only rollers 19; 21 tempering temperature control circuits 38 (38.1, 38.2, etc.) may be in the temperature control circuit 38 associated control process instead of a temperature setpoint T _s or a temperature range .DELTA.T a temperature _maximum value T _{max be} set or be. For this case, a simple embodiment may be that in the temperature control circuit 38 (38.1, 38.2, etc.) upstream or downstream of one or more swept, in the case of serial passage z. B. upstream of each first or downstream of the last traversed roller 19; 21, a sensor S04 is provided. This actual temperature T _is can - for example, according to empirically normalized (see above) - provide information about the roller temperature. In a safer embodiment, however, the temperature of the roller 19; 21 and roll surface detecting sensor S03; S03 '- z. B. per roller 19; 21 or at least on a roller 19; 21 per roller pair - to be provided.

For the preferred case, rollers 19; 21 several printing units 08, in particular rollers 19; 21 of several double printing units 17 can be tempered by a same tempering circuit 38, for example via a plurality of parallel tempering branches 38.x., the control of the relevant tempering circuit 38 can be carried out in such a way that measured values from comparable measuring points of different tempering branches 38.x are monitored, that none of the measured values exceeds the predefined temperature maximum value T _max (maximum value definition) or none of the measured values fall out of the permitted temperature range ΔT _s or tolerance range T _s ± Δ (nominal value definition). Should a difference between the branches be so great that the requirement can not be met simultaneously for all affected measuring locations (so that, for example, if the temperature has been raised, the previously too low value is raised to the permitted range, another one, however, is then z. B. above runs out of the permitted range), so can be adjusted above og adjustable valves 78, a relative flow rate, and thus within certain limits, a tempering, or reset.

In one of the possibilities of the embodiments described above with particular advantage for the tempering device 39, at least two control processes of temperature control circuits 37, which comprise two forme cylinders 12; 14 at least two print on the same side of the web 02 printing units 08 of the printing tower 01 temperature, different from each other, in particular to z. B. at least 0.5 ° C Differenzendesolltemperaturen T _soll (ie after above mentioned by at least 0.5 ° C target temperature values with possibly the same tolerance range, or offset by at least 0.5 ° C average values relative to the respective temperature range .DELTA.T _s ) have. The two form cylinder 12; 14 at least two printing on the same side of the web 02 printing units 08 of the printing tower 01 are or are in an operating situation z. B. traversed with fluid whose respective control process underlying target temperature T _is z. B. order at least 0.5 ° C. In this case, the setpoint temperature T _soll which _is the downstream of the printing unit 08 considered in the web running direction is preferably the higher one. The rolls to be tempered 19; 21, in particular distribution cylinder 19; 21, these two printing units 08 can here either advantageous by a same temperature control 38, or possibly also by two temperature control circuits 38, z. B. on the basis of the same values for the target temperature T _soll or the temperature _maximum value T _max , tempered or become, so that these rollers 19; 21 of the two printing units 08 in both cases to a same target temperature T _soll or a same temperature _maximum value T _max are regulated or are. The latter is z. B. advantageous if the two halves of arranged in the printing tower 01 double printing units 17 are tempered by different temperature control circuits 38 and are. In principle, however, different values for the setpoint temperature T _soll or the maximum temperature value T _{max can be} predetermined for two different temperature control circuits 38 of the pressure tower 01.

In one - especially i. V. m. Newsprint and / or the formation of the inking unit 09 as a roller inking unit 09 and / or the formation of the printing unit as a printing tower 01 and / or the formation of the printing unit 08 as a dry offset printing unit 08 - advantageous embodiment or operation are or will be at least two of the forme cylinder 12; 14, preferably all forme cylinder 12; 14 of the printing tower 01 heated in such a way that it at least in the production plant on its outer surface, an actual temperature T _is in the range from 22 ° C to 29 ° C, advantageously in the range 23 ° C to 28 ° C, preferably in the range of 24 ° C to 25 ° C, exhibit. This actual temperature T _is in operation depending on the amount of production speed, in particular depending on the production speed, within the specified range vary, in particular by appropriate consideration in one of the control and / or regulating device 49 implemented or one og, the tax and / or control device 49 upstream Sollwertbildenden process to be selectively varied. The temperature ranges given here for the actual on Formzylindermantel im Operation present or to be observed above actual temperatures T _is refer to z. B. to values, as they are, for example, by commercially available infrared measurement systems (IR measurement systems) when used properly and appropriate calibration - possibly only temporarily arranged for review - measurable. In this case, a value is to be used for the indicated values, which value can be determined by measurement on the component 12; 14; 19; 21 (here forme cylinder 12, 14) viewed in the axial direction at a lying within the printing width point, preferably spaced by at least 50 mm from the outer edge of the outermost printing form is located. This preferably applies to an average value which results from at least two measurement points lying within the pressure width and spaced apart axially from one another. The above-mentioned is also for the measurement of below mentioned actual jacket temperature to rollers 19; 21, in particular friction cylinders 19; 21, apply.

The control processes of all the forme cylinder 12; 14 of the printing tower 01 be tempered secondary circuits 37 is or is for example a corresponding setpoint temperature T _set (T _'to) specified which in the case of an application of the real sensor S03 or sufficiently well modeled and calibrated virtual sensor S03' z.

If, instead of the sensor S03 or S03 ', a sensor S02 used in the flow between the pump and the component is used for presetting and setting, then the above-mentioned values minus a difference value in the temperature, for example by 3 ° C., apply to the values to be preset. This also applies to the examples of forme cylinders 12 set out below; 14 and rollers 19; 21. This difference value or the desired value for the control circuit having the sensor S02 can also be determined or described in the modeling as described above.

With regard to the inking unit 09 are or will be in a- i. V. m. Newsprint and / or the formation of the inking unit 09 as a roller inking unit 09 and / or the formation of the printing unit as a printing tower 01 and / or the formation of the printing unit 08 as a dry offset printing unit 08 - advantageous embodiment or operation at least two of the above-mentioned heatable rollers 19; 21, advantageously at least the four heatable rollers 19; 21 of a double printing unit 17, preferably all temperature-controlled rollers 19; 21, in particular distribution cylinder 19; 21 of the printing tower 01 heated in such a way that it at least in the production plant on its outer surface, an actual temperature T _is in the range from 25 ° C to 33 ° C, advantageously in the range of 26 ° C bis31 ° C, preferably in the range from 27 ° C to 30 ° C, exhibit. This actual actual temperature T _ist may possibly vary within the specified range depending on the level of the production speed, in particular depending on the production speed, in particular implemented by appropriate consideration in one of the control and / or regulating device 49 or one of the abovementioned controls - And / or control device 49 upstream Sollwertbildenden process to be selectively varied. The temperature ranges given here for the actually on the rollers 19; 21 or roll shell present in operation or og to be observed actual temperatures T _is relate z. B. to values, as they are measurable or to measure, for example, in the above manner.

The control process or possibly the control processes of the rollers 19; 21 of the printing tower 01 tempering secondary circuit 38 and the rollers 19; 21 of the printing tower 01 be tempered secondary circuits 38 is or is, for example (in each case), a corresponding desired temperature T _set (T _'to) specified which in the case of an application of the real the outer surface temperature detecting sensor S03 or sufficiently well modeled and calibrated virtual sensor S03 'z. In the range of 25 ° C to 33 ° C, preferably in the range of 26 ° C to 31 ° C, preferably in the range of 27 ° C to 30 ° C.

Likewise, the above for form cylinder or Walzentemperierung mutatis mutandis to be transferred to executions, a target temperature and an actual temperature of a remote component destination are processed and the reference to the assumed actual jacket temperature already by experts or appropriate model "backwards" in the specification of the destination to be set Target temperature T _{is to be} processed. This is then by the underlying control process to maintain temperature at the component 12; 14; 19; 21 different destination to the relevant target temperature T _{should be} regulated, it being assumed that the z.

Overall, the tempering device 39 does not necessarily have to meet the requirements for accuracy and / or dynamics, as required, for example, in the case of a screen roll temperature control for color flow control. This can be reflected on the one hand in the z. B. above areas or tolerances, in particular for Walzentemperierung, but also for the Druckwerkzylindertemperierung can be chosen considerably larger. This can be a constant rules to a minimum. In addition or instead, pumps 47; 68 and / or actuators 51; 69 (valves) be dimensioned smaller in terms of their capacity and / or their control range, since usually no sudden changes and thus no excessive circulation quantities and / or feeds are required. Additionally or alternatively, as modified from the above embodiment, a temperature level of the fluid circulating in the primary circuit 43 (59) may be higher than required, for example, for screen roller tempering. The temperature of the flow of the primary circuit 43; 59 flowing fluid can be here, for example, at a temperature of 12 to 20 ° C, in particular even more than 15 ° to 20 ° C inclusive are advantageous here, however, sufficiently large recirculation and flow rates. Overall, a dynamic for at least the temperature of the forme cylinder 12; 14 sufficient, which in the interaction of flow rates, valve limitation, travel distances of the fluid and the temperature levels z. B. in the temperature range between 20 ° C and 30 ° C, a possible cooling rate of z. B. at least 0.5 ° C / min advantageously 1 ° C / mingewährleistet. However, the cooling rate (eg, measurable by means of a sensor S03, possibly temporarily attached, directed to the central region or preferably to the entry-distal end of the effective bale length of the component 12, 14, 19, 21) does not necessarily exceed 2 ° C / min go out. The same applies to the or the rollers 19; 21 tempering Temperierkreise 38 or Temperierkreis. However, these may possibly be even more sluggish.

In one - especially i. V. m. Newsprint and / or the formation of the inking unit 09, in particular as a roller inking unit 09, and / or the formation of the printing unit as a printing tower 01 and / or the o. G. Training and / or operation of the tempering device 39 - advantageous embodiment or mode of operation, the ink reservoir 25 at least one of the printing units 08, in particular the ink reservoirs 25 all the printing units 08 of a particular made of newsprint web 02 printing tower 01 an ink of special properties. This bears in particular i. V. m. with the by the aforementioned embodiments for the formation of the printing tower 01 and / or the printing and inking units 08; 09 and / or the tempering 39 created opportunities the special requirements for waterless printing on uncoated or slightly coated paper, especially newsprint, in a printing towers 01 having machine bill.

As competing requirements are here on the one hand, the possible "rupffree" color transfer to the (newspaper) paper, the most possible "tone-free" transfer to the printing form and a -. B. in spite of particularly high printing speeds in newspaper printing-good possible streak-free and / or splash-free color flow with good trituration in line. In an advantageous embodiment, therefore, during operation of the printing press or at least one printing tower 01, in particular in a retracted web 02 of newsprint (see above), an ink in the ink reservoir 25 at least one, in particular all co-operating with the web 02 printing units 08 of the printing tower 01, provided, which has advantageously set forth embodiment. It can (possibly should) the inks of the individual printing units 08 z. Although indeed vary in their property, but are still preferably all in the specified advantageous embodiments:

The values given here for the viscosity are understood to be on a Physica, z. B. Physica MC 100 (with recommended (minimum) sample quantity, plate-plate principle, measuring plate MP 30 (25 mm), gap distance 0.15 mm, shear rate D = 10 1 / s, measuring interval 5 sec., Ie 12 measurements / min, software US 200), the company Anton Paar to be measured viscosities, preferably under the conditions mentioned. A measuring point for a color in a specific parameter set is effected here, for example, by averaging the values of the 12 consecutive measurements within the measuring minute, wherein the first measured value is recorded after 5 seconds without additional warm-up time for the color. (Temperature with ± 0.5 ° C error range for viscosity values).

The values given here for tack Z are determined with the Inkomat 200 (Fa. Prüfbau) at the corresponding recommended parameters as "Inko" (with recommended sample quantity, here eg 1250 mm ³ , without pre-tempering of the color, trituration 30 sec at 50 m / min, then 2 min measuring time at speed V to be tested and temperature, read off at the end of the 2 min value as result). The determination can be in addition to the specified parameters z. B. also according to the standard ISO 12634: 1996 (E).

In a first embodiment, the ink (ink A) - z. B. in the ink reservoir 25 of all printing units 08 of the printing tower 01 - at 27 ° (corresponding, for example, the above advantageous temperature range of the rollers 19; 21) has a viscosity of at least 50 Pa * s, in particular at least 60 Pa * s. Are several, z. B. a number n, in particular n = 4, colors assigned to a same side of the web to be printed 02, so for at least two consecutive printing units 08, the viscosity of the ink of the downstream printing unit 08 is higher than the upstream. Preferably - z. B. with respect to a temperature control of the printing units 08 - soft the viscosities of n a same side of the web 02 associated printing inks by a maximum of 20% of the above minimum value, z. B. by a maximum of 10 or 12 Pa * s, from the mean over the n colors.

At this measurement temperature of 27 ° (± 1 ° C) and a speed V of 10 m / s (± 0.03 ° m / s), which is within the range of production speeds, the tack Z of the advantageous printing ink (color A in Fig. 17 ) of the first embodiment at most at 10.0 Inko (tack value measured in Inko, see above), advantageously at most 9.5 tack, z. B. between 6.0 and 9.5 Inko, preferably between 7.0 and 9.5 Inko. This is true at least for an average value of the measured values from the n (eg n = 4) to be applied on a same side of a same web 02, located in the ink reservoirs 25, but also individually for all n (4) printing inks. In the event that the tack Z of the color at this temperature T of about 27 ° C in the range of speed V of 6 to 10 m / s has a significant dependence on the speed V, z. B. that a determined by the two measurement points at 6 m / s and 10 m / s mean value for the gradient (.DELTA.Z / .DELTA.V) z. B. 0.06 Inko / (m / s) or greater, then this ink should at a speed V of 6 m / s at the same time have a significant dependence of the speed Z of the temperature T, z. B. determined by the two measurement points at 20 ° C and 27 ° C average for the gradient (.DELTA.Z / .DELTA.T) z. Eg -0.06 Inco / ° C or even steeper (ie a larger negative number). As a result, an effective control option is ensured in the event of significant speed-dependent tack. Basically preferable, however, is a printing ink which has a gradient of less than 0.06 Inko / (m / s), in particular less than 0.03 Inko / (m / s) in the above-mentioned speed range. In this case, the temperature dependence may be reduced and the gradient between -0.06 and 0.00 Inko / ° C, in particular between -0.03 and 0.00 Inko / ° C lie.

In the first exemplary embodiment, the printing ink has a viscosity of at least 80 Pa * s, in particular at least 24 ° C., ie at 24 ° ± 1 ° C. (corresponding, for example, to the above-mentioned advantageous temperature range of the forme cylinder 12; 110 Pa * s up. Are several, z. B. a number n, in particular n = 4, colors assigned to a same side of the web to be printed 02, so here is for at least two successive printing units 08, the viscosity of the ink of the downstream printing unit 08 z. B. higher than the upstream. Preferably - z. B. with respect to a temperature control of the printing units 08 - soft the viscosities of the n a same side of the web 02 associated inks here by a maximum of 20% of the above minimum value, z. For example, by a maximum of 16 or 22 Pa * s, from the mean over the n colors.

At this measurement temperature of 24 ° C. (± 1 ° C.) and a speed V of 10 m / s (± 0.03 ° m / s) lying in the range of production speeds, the tack Z of the printing ink advantageously arranged in the ink reservoirs 25 should be first embodiment at the most at 10.5 Inko (tack value measured in Inko, see above), advantageously at most 10.0 tack, z. B. between 6.50 to 10.0, preferably between 8.0 and 10.0 Inko, are. This is true at least for an average value of the measured values from the n (eg n = 4) to be applied on a same side of a same web 02, located in the ink reservoirs 25, but also individually for all n (4) printing inks. In the event that the tack Z of the color at this temperature of about 24 ° C in the range of speed V of 6 to 10 m / s has a significant dependence on the speed V, z. B. that a determined by the two measurement points at 6 m / s and 10 m / s average for the gradient (.DELTA.Z / .DELTA.V) here z. B. 0.04 inco / (m / s) or greater, then this ink should at a speed V of 6 m / s at the same time have a significant dependence of the speed Z of the temperature T, z. B. as above by the two measurement points at 20 ° C and 27 ° C determined average value for the gradient .DELTA.Z / .DELTA.T) z. Eg -0.06 Inko / ° C or even steeper. Basically, however, an ink with little or no speed dependency in the tack Z as mentioned above is preferable here as well.

In an advantageous variant, the tack Z varies at z. B. at least two, preferably in all of n consecutively arranged on a same side of the web 02 printing units 08 at 24 ° C and a speed V of 10m / s targeted in such a way that the tack Z at the parameters mentioned from color to color (eg black, yellow, magenta or cyan). However, this is preferably for the respective above conditions within a maximum of z. B. Inko, but advantageously within the above specified for the respective conditions maximum limits or intervals. This embodiment is for example advantageous with a tempering device 39, wherein at least the rollers 19; 21 of two of four consecutively arranged on a web page printing units 08 in pairs tempered by a respective Temperierkreislauf 38, or all four by a common Temperierkreislauf 38. The mentioned grading in the speed then applies z. B. for the connected via a common Temperierkreis 38 printing units 08th

In a second embodiment of the in the ink reservoirs 25 of the printing tower 01 arranged or used inks (ink B), this has a tendency to even higher viscosity but further reduced toughness Z on. Thus, the viscosity here at a temperature of 27 ° C to e.g. at least 80 Pa * s, in particular at least 90 Pa * s. At 24 ° C it is e.g. at least 120 Pa * s, in particular at least 130 Pa * s. For the values at n printing units 08, etc., the above applies mutatis mutandis.

The speed Z is lower in the second embodiment of the ink (ink B) and has z. B. at 27 ° C a tackiness Z of at most 7.5 Inko, in particular at most 6.5 Inko, z. B. 3.5 to 7.5 Inko, in particular 3.5 to 6.5 Inko, on. At 24 ° C, it then z. B. a tackiness Z of at most 8.5 Inko, in particular at most 8 Inko, z. B. 4.0 to 8.0 Inko, especially 4, 0 to 7.5 Inko, on. The above to possibly present gradient in terms of speed and / or temperature dependence applies mutatis mutandis accordingly. Here, however, would be z. B. at a temperature of 27 ° C in the event that a by the two measurement points at 6m / s and 10 m / s determined average value for the gradient (.DELTA.Z / .DELTA.V) z. B. 0.04 Inko / (m / s) or greater, an ink advantageous whose tackiness Z at a speed of 6 m / s has a significant dependence on the temperature T, z. B. one through the both measuring points at 20 ° C and 27 ° C determined mean value for the gradient (.DELTA.Z / .DELTA.T) z. B. -0.04 Inko / ° C or even steeper (ie a larger negative number in terms of amount) is. In principle, however, an ink which has a gradient of less than 0.04 Inko / (m / s), in particular less than 0.02 Inko / (m / s), is also preferable here in the above-mentioned speed range. In this case, the temperature dependence may be reduced and the gradient between -0.04 and 0.00 Inko / ° C, in particular between -0.02 and 0.00 Inko / ° C liegen.Am measuring point at 24 ° C applies to the case that the tack Z of the color at this temperature of about 24 ° C in the range of speed V of 6 to 10 m / s has a significant dependence on the speed, z. B. that a determined by the two measurement points at 6 m / s and 10 m / s average for the gradient (.DELTA.Z / .DELTA.V) here z. B. 0.03 Inko / (m / s) or greater, then this ink should at a speed V of 6 m / s at the same time have a significant dependence of the speed Z of the temperature T, z. B. as above by the two measurement points at 20 ° C and 27 ° C determined average value for the gradient (.DELTA.Z / .DELTA.T) z. B. - 0.04 Inko / ° C or even steeper. Basically, however, a printing ink with little or no speed dependency in the tack Z is also preferable here as mentioned above. The execution of the printing unit 08 with the color B contains z. B. advantages in terms of a further improved Rupfverhaltens, but the handling is ensured in the inking unit train by increased viscosity.

In a non-illustrated third embodiment of the arranged in the at least one ink reservoir 25, in particular in the ink reservoirs 25 of the printing tower 01 or ink used (ink C) this combines the advantages of the ink B and the ink A in such a compromise that z. B. the viscosity here at a temperature of 27 ° C to eg at least 70 Pa * s, in particular at least 80 Pa * s. At 24 ° C it amounts z. B. to at least 100 Pa * s, in particular to at least 110 Pa * s. For the values of n printing units 08 etc. the above applies to ink A mutatis mutandis.

The tackiness is in the third embodiment of the ink at 27 ° C, e.g. not more than 9,0 Inko, in particular not more than 8,5 Inko, z. B: at 4.5 to 9.0 Inko, in particular 5.0 to 8.5 Inko. At 24 ° C, it then z. B. a tackiness Z of at most 9.5 Inko, in particular at most 9.0 Inko, z. B. 5.0 to 9.5 Inko, in particular 5.5 to 9.0 Inko on. With regard to the values for n printing units 08, the same applies to ink A above and to the gradients, the same applies to the ink B mentioned above.

Preferably, however, the viscosity in all three embodiments for 24 ° C is at most 280 Pa * s, in particular at most 230 Pa * s and for 27 ° C at most 180 Pa * s, in particular at most 130 Pa * s.

The printing press is preferably designed such that in one embodiment at least one printing tower 01 in one mode of operation (coldset) cooperates with a web 02 of newsprint, and in a second mode of operation (heatset) with a web 02 'of higher quality printing material, e.g. B. paper, hereinafter referred to, for example, as a semi-commercial paper, acts together (see, for example, the in Fig. 1 from the left printing tower 01 coming train 02; 02 '). In both modes of operation, the ink reservoirs 25 of the printing tower 01 each have a same printing ink described above. In the heatset mode, the web 02 'is or are guided after printing by an active dryer 05, before it is - optionally longitudinally cut in partial webs - fed to one or more formers of the hopper assembly 04 or is. In coldset operation, however, the web 02 after printing is supplied to the hopper assembly 04 without an activated dryer. This can be done without a dryer on the guide way, or with a deactivated dryer 05 on the guide. In coldset and heatset mode, one and the same - z.

B. on the roughness and / or surface porosity distinctive Semocommercialpapier (see below) printed by dry offset, wherein in both Operations of the same type of ink in the color reservoirs 25 is used. D. h., It must be provided or be no different color supply for the two modes of operation of the printing tower 01 or a complete cleaning when changing. The temperature of the printing tower 01 may differ in that, for example, in the heatset for the temperature of the printing cylinder 12; 14, in particular form cylinder 12; 14 regulating processes another, z. B. compared to the above for newspaper printing examples by at least 1 ° C lower target temperature T _is set or will be.

In addition or instead, the printing press may also preferably be designed such that in one embodiment at least one of several printing towers 01 in one mode (coldset) with a web 02 mentioned above made of newsprint and at the same time another printing tower 01 in a second mode (heatset) a web 02 'from higher quality printing material, eg. B. paper, hereinafter referred to as, for example, semicommercialpapier acts together or is operated (see, eg. Fig. 1 ). In both printing towers 01, the color reserves 25 of the respective printing tower 01 z. B. each have a same type of ink described above. D. h., It must be provided no different from each other ink supply for the two different operated towers 01. The printed in Heatsetbetrieb, ie dried after printing through a dryer 05, web 02 'is or is performed after printing by an active dryer 05 before it is guided on the funnel assembly 04 or is. Preferably, the web 02 produced in the coldset or a part web produced therefrom by longitudinal cutting and the web 02 'produced in the heatset or a part web produced therefrom by longitudinal cutting are or are jointly guided on the same hopper assembly 04, in particular a same former to produce a product. The (newspaper) printing press can then, for example, have a larger number of printing towers 01 than dryer 05.
