A printing press, in particular a web-fed rotary printing press for printing one or more webs B, has a plurality of assemblies 100; 200; 300; 400; 500; 600; 700; 800; 900 for material supply 100, for printing and further processing. From Z. B. a roll handling 100 to be duckled web B, in particular paper web B, unwound before it is fed via an infeed 200 one or more printing units 300. Additional printing units 300 can be provided for the printing units 300 (eg four pieces for four-color printing) provided by default for multi-color printing, which can then also be used, for example, alternately with one or more of the remaining printing units 300 for the flying printing form change.

In an advantageous embodiment, a coating unit 400 may be provided in the web path.

After printing and optionally painting, the web B passes through a dryer 500 and is optionally cooled again in a cooling unit 600, if the drying takes place in a thermal manner. After the dryer 500, in or after the cooling unit 600, at least one further, in Fig. 1 Not shown conditioning, such. B. a coating device and / or a Wiederbefeuchtung be provided. After cooling and / or conditioning, the web B can be fed via a superstructure 700 to a folding apparatus 800. The overbuilding 700 has at least one not in FIG. 1 illustrated silicone work, a longitudinal cutting and a turning device and a funnel unit. The said silicone work can also be before the superstructure 700, z. B. be arranged in the region of the cooling unit 600. The Überbaubau 700 can continue in Fig. 1 not shown Perforierwerk, a gluing unit, a numbering and / or a Pflugfalz have. After passing through the superstructure 700, the web B or partial webs are fed into a folding apparatus 800.

In an advantageous embodiment, the printing machine additionally has a separate cross cutter 900, z. B. a so-called. Plano boom 900, in which a, for example, not guided by the folder 800 web B cut into format sheets and possibly stacked or designed.

The aggregates 100; 200; 300; 400; 500; 600; 700; 800; 900 of the printing press have an effective width transversely to the transport direction T of the web B, which processing of webs B of a maximum width b ( Fig. 2 ) from Z. B. up to 1,000 mm allowed. Under effective width here is the respective width or clear width of the directly or indirectly cooperating with the web B components (eg, roller, cylinder, implementation, sensors, travel paths, etc.) of the units 100; 200; 300; 400; 500; 600; 700; 800; 900 so that the web B can be processed, conditioned and conveyed in its full width b. Furthermore, the aggregates 100; 200; 300; 400; 500; 600; 700; 800; 900 in their functionality (material supply, rail transport, sensors, further processing) designed such that even partial width webs B 'in the printing press down to a width b' of only 400 mm are processed.

The aggregates 100 defining or processing a section length a; 200; 300; 400; 500; 600; 700; 800; 900 are configured to define, for example, a section length a lying between 540 and 700 mm on the path B. Advantageously, the section length a is between 540 and 630 mm. In a specific embodiment, the section length a is 620 ± 10 mm. In training of Printing machine are the aggregates 100; 200; 300; 400; 500; 600; 700; 800; 900 designed so that with a few changes, the printing machine with optional section length 546 mm, 578 mm, 590 mm or 620 mm is executable. Thus, for example, essentially only an interchangeability of bearing elements for printing cylinder (see below), an adjustment of the drive (see below) and an adjustment in the folder 800 and the cross cutter 900 (see below) required to equip the same printing press for different formats , The section length a is, for example, standard with four stationary printed pages, z. B. DIN A4, in the transverse direction of the web B side by side and two printed pages (for example, a length s) in the longitudinal direction one behind the other. Depending on the printed image and subsequent further processing in the superstructure 700 and folder 800, however, other page numbers per section length a are possible.

The roll handling 100 can be used as a standstill roll changer with web storage or else advantageous, as in Fig. 3 illustrated, designed as a reel changer 100 for the flying reel change. He has several, here two, pairs of brackets 101; 102, which on a support 103 in pairs in an alignment parallel to the axis of rotation of a roll to be unwound 104; 106 are mounted individually movable. The split, individually movable support arms 101; 102 allow the simultaneous inclusion of rollers 104; 106 different width b '; b by the support arms 101 and 102 ( Fig. 3 ). The axial movement takes place for example via drive motors 107 and / or spindle drives, not shown. The carrier 103, the total as in Fig. 2 represented z. B. is designed in several parts, is one to the axes of rotation R104; R103 parallel to the central axis R103 motor mounted in a frame 109 or in frame walls 109 pivotally, wherein the two pairs of support arms 101; 102 are preferably offset by 180 ° about the central axis R103 to each other. Cones 111 accommodating a roll core are rotatory, for example via a belt drive, by a drive motor 112 on a cone 111 per pair of support arms 101; 102 drivable. The other cone 111 is not driven in each case.

The axial positioning of the respective support arm 101; 102 is determined, for example, by a control and / or regulation 114, which is indicated only schematically, on the basis of a desired value y-soll for the position of the roller 104, for example, manually (for example, from the control panel) or a machine control. 106 or y-soll, i for the support arms 101; 102 made. The setpoint values y-soll, i for the support arms 101; 102 may also be in the controller 114 or otherwise, for. B. from the setpoint y-should be formed. For detecting the actual position y-ist of the respective support arm 101; 102, the drive and / or the carrier 103 may be associated with a sensor, not shown, which reports back the position to the controller 114 and / or control. A sensor can be omitted if, for example, the actual axial position is correlated via a rotor position and present as information. If the current position y-ist (via the sensor system or the correlation) does not coincide with the current setpoint value y-soll, then the control and / or regulation 114 in turn acts with a corresponding adjustment command Δ107 on the respective drive motors 107. A control process can be more advantageous Be provided manner in which the new aufgeachste role, z. B. roller 106, the currently running role, z. Roll 104 (or web B, B ') is automatically aligned in the axial direction before the new web B; B 'by means of an adhesive and cutting device 108 to the outgoing web B'; B glued, and the old train B '; B from her roll 104; 106 is separated. Also, it is by the driven support arms 101; 102 possible and provided that after receiving a new roll 104; 106, or before the start of production, the role of 104; 106 automatically positioned in its axial position with respect to the desired web edge course and thus the web edge is preset. Corresponding information about the planned production and / or default values is given to the controller of the roll changer 100 by the machine control of the printing machine.

The roll changer 100 is prepared in an advantageous embodiment for being operated from both sides, ie in the region of both frame walls 109. These are at least in both frame walls 109 already in the production at least connection points (eg coverable recess in the frame wall and / or coverable openings for signal lines) for receiving a control element 116, z. B. a display 116 with appropriate input or switching elements provided. Depending on the definition of a provided during the installation of the machine for their operation side I, the operating side I, the recess of the opposite side II can be closed by means of a lid, not shown, in a first embodiment, while on the side provided for operating the machine I the Control 116 is installed. In another embodiment, the reel changer generally has an operating element in both frame walls 109 (side I and II).

The two-sided or optional equipment with controls 116 is particularly advantageous in the context of the arrangement of the roll changer 100 both in so-called. Left-right and in so-called. Right-left machines without that own solutions must be created in design and manufacture , As left-right or right-left machine should be understood here in the manner that this is the transport direction T of the web B; B 'indicates when the machine is viewed from the longitudinal side from which the operation is provided by the staff, ie from the operating side I forth. In Fig. 1 it is thus a left-right machine assuming that the viewer is on page I. The above also applies to the printing units 300, pull-in elements, switch cabinets 361 and longitudinal bars 362, which are specially designed for this purpose.

For multicolor printing of web B; B 'the press has several, z. B. at least four, in particular five substantially equally equipped printing units 300. The printing units 300 are preferably arranged side by side and are of the web B; Go through B 'horizontally. The printing unit 300 is preferably used as a printing unit 300 for offset printing, in particular as a double printing unit 300 or as an I-printing unit 300 with two printing units 301, z. B. two offset printing units 301 designed for the two-sided printing in the so-called rubber-against-rubber operation. At least one of the printing units 300 are at least in the lower region, and optionally in the upper region, upstream and downstream rollers 302, by means of which an incoming web B; B 'can be guided around the printing unit 300 at the bottom or at the top, a web B guided around an upstream printing unit 300; B 'can be carried out by the printing unit 300, or a web B performed by the printing unit 300; B 'is guided around the downstream printing unit 300.

Fig. 4 shows schematically the arrangement of two over the web B; B 'co-operating printing units 301, each with a cylinder 303 designed as a transfer cylinder 303 and as a forme cylinder 304; 304, also as printing cylinder 303; 304, an inking unit 305 and a dampening unit 306. In an advantageous embodiment, the printing unit 300 per form cylinder 304 has devices for semiautomatic or fully automatic plate feed 307 or exchange of a printing forme 310.

In a further development, in particular if the printing machine is to be suitable for an imprinting operation, at least one or more printing units 300 have additional guide elements 308 close to and behind the nip point of the printing unit 300. If a printing unit 300 without printing and without contact between web B; B 'and transfer cylinders 303 are passed through, the dashed line is in Fig. 4 illustrated web guide using the guide elements 308 advantageous. The web B; B 'passes through the nip so that it is at an angle of 80 ° to 100 °, z. B. forms about 90 °. The guide elements 308 are preferably designed as lutumspülte rods or rollers. This reduces the risk of abrasion of previously freshly printed paint.

In a further development of the illustrated printing unit 301, each transfer cylinder 303 is assigned a washing device 309. By means of the washing device 309, the elastic surface of the transfer cylinder 303 to be cleaned.

The cylinders 303; 304 each have a circumference between 540 and 700 mm, wherein preferably form and transfer cylinder 303; 304 have the same extent. Advantageously, the circumferences are between 540 and 630 mm. In a specific embodiment, the section length a is 620 ± 10 mm. In a further development, the printing unit 300 is designed in such a way that, with a few changes, cylinders 303; 304 with a circumference of 546 mm, 578 mm, 590 mm or 620 mm is executable. Thus, for example, only an exchange of bearing elements or a changed position of the holes in the side frame (and sprue; s.u.) For the cylinder 303; 304 and an adjustment of the drive (lever, s.u).

The transfer cylinder 303 has on its circumference at least one elevator, not shown, which is held in at least one axially extending on the lateral surface channel. Preferably, the transfer cylinder 303 has only one over the effective length or substantially over the entire width of the web B to be printed; B 'reaching and substantially (except for a shock or a channel opening) to the entire circumference of the transfer cylinder 303 reaching elevator. The elevator is preferably embodied as a so-called metal printing blanket, which has an elastic layer (eg rubber) on a substantially dimensionally stable carrier layer, eg. B. a thin metal plate having. The ends of this elevator are now introduced through an opening on the lateral surface in the channel and friction or held there form-fitting. In the case of a metal printing blanket, the ends are bent / folded (eg in the region of its leading end by approximately 45 ° and in the region of its trailing end by approximately 135 °). These ends extend through an opening of a channel extending axially over the entire width of the transfer cylinder 303, which, for example, likewise has a locking, clamping or tensioning device. The opening to the channel preferably has a width in the region of the circumferential surface in the circumferential direction of the cylinder 304 from 1 to 5 mm, in particular less than or equal to 3 mm. The clamping is advantageously pneumatically actuated, z. B. as one or more pneumatically actuated lever, which are biased in the closed state by spring force against the reaching into the channel trailing end executed. As an actuating means is preferably a pressurizable medium beaufschlagbarar hose used.

The inking unit 305 has in addition to a color feeder, z. B. a color box 311 with a regulator 312 for regulating the flow of color, a plurality of rollers 313 to 325 on. The ink feed 311 can also be designed as a doctor bar. The ink passes with rollers 313 to 325 from the ink fountain 311 via the ductor roller 313, the film roller 314 and a first ink roller 315 to a first distribution cylinder 316. From there, the ink passes, depending on the mode of operation of the inking unit 306 (see below), over at least an ink roller 317 to 320 on at least one further distribution cylinder 321; 324 and from there via at least one application roller 322; 323; 325 on the surface of the forme cylinder 304. In an advantageous embodiment, the color passes from the first distribution cylinder 316 via different possible ways either selectively or simultaneously (in series or in parallel) via two further distribution cylinder 321; 324 to the applicator rollers 322; 323; 325. In an advantageous embodiment of the inking and dampening unit 305; 306, the second distribution cylinder 324 may simultaneously with a roller 328, z. B. applicator roller 328, the dampening unit 306 act together.

In a further development, the inking unit 305 has, in addition to the rollers 313 to 325, at least one further roller 326, by means of which ink in the ink path, in particular in front of the first distribution cylinder 316, can be removed from the inking unit 305. This takes place by means of this roller 326 itself, or, as shown, on a roller 327 cooperating with this roller, a corresponding removal device 333 (FIG. Fig. 4 ).

The roller 328 acts with another roller 329 of the dampening unit 306, z. B. a friction roller 329, in particular a iridescent chrome roller 329 together. The Chrome roller 329 receives the dampening solution from a moistening device, eg. B. a roller 330, in particular a fountain roller 330, which in a dampening solution supply 332, z. B. a water tank, diving. Under the water tank a drip tray 335 is preferably arranged for collecting condensation forming on the water box, which can be heated in an advantageous embodiment, for. B. by means of heating coil is executed. For the friction roller 329 and the fountain roller 330 is ever a rotary single drive (in Fig. 5 not visible), in particular a drive motor provided, which z. B. via a corner or bevel gear, the respective roller 329; 330 mechanically independently rotatably drives individually. The drive motor is preferably designed as a. Adjustable speed (in particular continuously) electric motor, in particular three-phase motor. The setting of the speeds or the humidification can advantageously from the control center, z. B. from the color control desk, where it is displayed. In a preferred embodiment, the machine control is a correlation between machine speed and dampening or speed deposited by which the speed of the two rollers 329; 330, in particular the roller 330, can be predetermined.

The rollers 317; 318; 328 are arranged in an advantageous embodiment in the manner indicated by solid and dashed lines movable manner. Under the mobility of the rollers 317; 318; 328 is not to be understood here as the usual adjustability given for adjustment purposes, but the operational mobility for conversion from one to the other operating position. Ie. Manual or actuatable actuating means and / or stops (eg adjustable) are provided for both the one and the other operating positions. Furthermore, there is a larger allowable travel or before the roller assembly is chosen so that the two layers can be reached by the usual travel.

In an advantageous embodiment, the chrome roller 329 and the roller 330 are each movable in a direction perpendicular to its axis, z. B. in levers, stored so that the position the applicator roller 328 is changeable in the above manner.

The distribution cylinders 316; 321; 324 of the inking unit 305 and the roller 329 of the dampening unit 306 are in side frames 352; 353 or frame walls 352; 353 (see Fig. 5 ) axially movably mounted so that they can exert a traversing movement. The traversing movement takes place for the distribution cylinder 316; 321; 324 and the roller 329 z. B. forced via corresponding gear coupled to the respective rotary drive. For the roller 328 and the applicator roll 323 a storage is also provided, which allows a traversing. In contrast to the former Reibzylindern 316; 321; 324 and the roller 329, however, the axial movement is caused only by friction of the cooperating lateral surfaces and not via a corresponding traversing gear. Optionally, such a degree of freedom enabling storage in the axial direction can also be provided for the two applicator rollers 322 and 325.

In the Fig. 4 illustrated continuous arrangement in the inking and dampening unit 305, 306 shows the intended for the "normal" printing operation interaction of the rollers 313 to 330. Color and dampening means are in addition to the forme cylinder 304 and the second distribution cylinder 324 with each other. It takes place next to direct and indirect dampening.

By a mobility or adjustability of the roller 328 is a choice between a direct humidification in the "three-roller dampening unit" and - depending on the position of roller 317 - an indirect humidification or direct humidification in the "five-roller dampening unit" possible.

The cylinders 303; 304 and the rollers 313 to 330 of inking and dampening unit 305; 306 are each frontally in or on frame walls 352; Stored 353. Exemplary are in Fig. 5 however, only the rollers 329 and 330 and also explained below Main drive 354 of the printing unit 300 shown.

One of the frame walls 352; 353, in particular that on the side of the main drive 354, is one or more parts designed such that a lockable cavity 356, z. B. lubricant space 356, can be formed, which extends at least over an area, the front side all cylinders 303; 304 and with the cylinders 303; 304 in mechanically driving connection standing rollers or distribution cylinder, in particular distribution cylinder 316; 321; 324 of the inking unit 306, stand, covered. As in Fig. 6 shown schematically, a detachable cover 357 is provided for the cavity 356 frontally. The other frame wall 352 forms with a detachable, front side arranged cover 358 a cavity 359, in which inter alia, the switching and control devices 361 (dashed lines), z. B. in the form of a cabinet 361, the printing unit 300 are housed. The frontal arrangement of the switching and control devices 361, in contrast to the arrangement between the printing units 300 gives the advantage that the space between two printing units 300 can be walked on from both sides. An operating side I of the printing press is thus basically freely selectable (so left-right machine, right-left machine). This is further supported by the fact that a longitudinal cross-piece 362 connecting the printing units 300 can optionally be arranged on the frame wall 352 or 353 ( Fig. 6 : on the frame wall 352, the longitudinal bar 362 is shown by dashed lines). The arrangement of this longitudinal beam 362 thus defines the operating side I as the opposite side of the cross member 362 and vice versa results from the choice of the operating side I, the arrangement of the cross member 362. For the optional arrangement of the cross member 362 are preferably already during the manufacture of the racks 352; Provided 353 each prepared connection points 397. These may, for example, be in the nature of flanges with surface-treated surfaces (as opposed to rough casting) and holes for attachment.

The same is optionally valid for the preparation of a retracting device 399 (for example designed as a retraction guide 399 for a pulling-in means, not shown) through the printing unit 300. At least here in both side frames 352; 353 in each case already be prepared connection points 398 (eg machined surface with bore (s)) for receiving the Einziehführung 399. Also not shown supply channels (energy, signal lines, resources) between the printing units 300 and corresponding connection points for this can already in both side frames 352; 353 be prepared. These supply channels then run, for example, on the ultimately selected side II, preferably in the region of the longitudinal bar 362.

As mentioned above for the roll changer 100, at least in each of the frame walls 352; 353 a recess and / or a connection point in the form of a coverable recess in the frame wall and / or as coverable openings for signal lines) for a control element 390, z. B. a display 390 plus appropriate input or switching elements, such as a touch-sensitive display prepared.

In Fig. 6 it can be seen that the rotary individual drives 364; 365 of the rollers 329; 330 are arranged on the main drive 354 opposite machine side.

The roller 329 has on the opposite end of the rotary drive a traversing drive, not shown, in particular a gear for generating an axial traversing movement from the rotational movement. This gear is preferably arranged outside of the roller body in order to avoid selective generation of frictional heat in the roller 329. In an advantageous embodiment, this transmission is located on the drive side of the printing unit 300, ie in the region of the same frame wall 353 as the main drive 354 and / or a drive train of the printing cylinder 303; 304, the rotary drive of the rollers 329 and 330, however, on the opposite side, ie in the region of the frame wall 352. If the cavity 356 designed as a lubricant chamber 356, so the transmission to generate the axial traversing movement as an open, not specially lubricated transmission can be arranged in this. The roller 329 is on the transmission side for generating the axial traversing movement away side with the motor shaft of the drive motor 364 z. B. via a corner gear and an angle compensating coupling and a coupling means connected such that a rotational movement transmitted, however, an axial movement of the roller 329 relative to the shaft is possible.

On the cylinders 303; 304 facing side, the frame walls 352; 353 each one from the flight of the respective frame wall 352; 353 outstanding approach 363 on. The projection 363 is advantageously integral with the side frame 352; 353 and is preferably produced in the production in a mold as so-called. Sprue 363. The sprue 363 points through it and the flight of the frame wall 352; 353 reaching holes for receiving bearings, not shown. The sprue 363 extends, in particular contiguous, over the frontal region of the forming and transfer cylinders 303; 304, but not over frontal areas of iridescent and / or changeable inking or dampening rollers.

As in Fig. 5 already recognizable, the drive of the cylinder 303 takes place; 304 of the printing unit 300 via a main drive 354, z. B. a frame-fixed electric motor 354, in particular via a respect to its angular position adjustable electric motor 354, which is advantageously carried out water-cooled. The drive is preferably via a transmission (eg gear or belt transmission) from the drive motor to at least one of the cylinders 303; 304th

In Fig. 7 the arrangement of the drive is viewed from the frame wall 353 ago viewed from the outside. The electric motor 354 drives with his not in Fig. 7 visible pinion 383 (dashed arrow) not directly on a drive wheel 386; 387 one of the cylinders 303; 304, but via an intermediate gear 384. The idler 384 is mounted in a lever 388, which is mounted pivotably about a rotation axis R383 of the pinion 383 in principle. With a fixed position of the electric motor 354 with respect to the side wall 353 of the frame can be done for different sized printing units 300 in a simple manner to adapt to different cylinder circumferences (and thus different circumferences of the drive wheels 386, 387). Depending on the format of the printing unit 300, the lever 388 is pivoted during assembly so that the intermediate gear 384 in optimal engagement with the respective drive wheel 386; 387 stands. Advantageously, fixing elements 389, z. B.
