Description

The invention relates to a printing unit of a printing press with a pivotable Transfer cylinder according to the preamble of claim 1.

From DE 198 03 809 A1 a printing unit is known, the forme cylinder on which Has a circumference in the circumferential direction and a plurality of pressure plates in the longitudinal direction. A transfer cylinder cooperating with the forme cylinder has one double the circumference and is in the circumferential direction with a printing blanket and in Longitudinal direction with two, but offset to each other in the circumferential direction Printing blankets executed.

JP 100 71 69 4 discloses printing group cylinders with four juxtaposed, and circumferentially offset channels. The printing unit cylinders point a so-called double extent.

CH 345 906 discloses a device for bumpless printing, whereby Impacts of four elevators arranged side by side on transfer cylinders double the circumference and joints of four lifts arranged side by side on one Forme cylinders of double circumference are arranged offset from one another.

A double printing unit is known from DE 198 15 294 A1, the rotation axes the printing unit cylinders are arranged in one plane. The cylinders have one four times the width of a newspaper page (double width) and a circumference of one height Newspaper page on. The transfer cylinders have endless sleeves, which are on the side are interchangeable through openings in the side wall.

From US 41 25 073 A printing unit cylinders of simple scope are known, which have a vibration damper. In the case of wider printing presses, the Forme cylinder a double circumference and two pressure plates arranged one behind the other on. Those arranged side by side in the longitudinal direction, receiving the pressure plates Channels are additionally offset from one another in the circumferential direction.

From DE 44 15 711 A1 a double printing unit is known, for the purpose Improving the print quality a plane perpendicular to the paper web to the two Rotation axes of the plane connecting the transfer cylinder by approximately 0 ° to 10 ° is inclined.

JP 57-131 561 discloses a double printing unit arranged in one plane Axes of the printing unit cylinders. The printing unit cylinders are in their phase arranged to each other that channels for fastening the lifts to each other, and in unroll the two printing units working together.

DE 34 12 812 C1 also discloses a double printing unit, the Cylinder axes are arranged in a common plane, which is against the plane the web to be printed runs inclined. Starting and stopping the Transfer cylinder takes place along an almost rectilinear direction of movement using double eccentrics.

EP 08 62 999 A2 discloses a double printing unit with two working together Transfer cylinders, which are used in the eccentric or Double eccentric bushes are stored. In another version, they are stored in levers, which are pivotally mounted eccentrically to the forme cylinder axis.

DE 44 35 986 A1 describes a device for switching on and off Transfer cylinder in a printing unit with angularly arranged to each other Known cylinders, the one mounted in a lever around the forme cylinder Transfer cylinder for starting first by a first actuating means Eccentric on the forme cylinder, and then by a second, on the lever attacking actuating means is placed on the impression cylinder. The lever is closed Adjustment purposes eccentrically on the pin of the forme cylinder.

EP 07 41 013 A2 describes a printing press with bridge-shaped printing units is known, which is stored in levers to form a walk-in space Transfer cylinder pivotable about the axis of rotation of the associated forme cylinder are.

DE 44 02 389 A1 discloses four printing unit cylinders lying in one plane, whereby the transfer cylinders are mounted in swiveling levers. Turning off the Cylinder from each other is made by pivoting the forme cylinder, one of the Transfer cylinder due to the pivoting of the forme cylinder and as a result of Gravity is turned off by the cooperating transfer cylinder.

The invention has for its object a printing unit of a printing press with a to create pivotable transfer cylinder.

The object is achieved by the features of claim 1.

The advantages that can be achieved with the invention consist in particular in that Measures a printing press is created, which is compact, low-vibration and is robustly built, has a large variety of products, and is proportionate low manufacturing and maintenance requirements.

Minimizing the number of moving in normal operation and when setting up parts to be executed, e.g. B. the waiver of the movement of all cylinders, of Frame walls, bearings, etc., ensure the robust and inexpensive construction.

With the linear arrangement of the printing unit cylinders, i. H. the arrangement of the Rotation axes of the printing unit cylinders in the print-on position essentially in one Level, the cylinders support each other. This diminishes a relative Deflection of the cylinders. It is even a compensation of the bending line (static) of the Forme and transfer cylinder reachable to each other.

Because the elevators on the cylinders are not continuous over the length of the cylinders, but are held in circumferentially offset channels, a Channel blow when passing through the channel while rolling two together acting cylinder significantly reduced. In an advantageous embodiment, the channels are in the Case of two channels arranged side by side in the longitudinal direction by 1 8 0 ° to each other staggered.

The arrangement of the printing couple cylinders and the channels is particularly advantageous, that the offset channels of each cylinder in the area of the opposite lying, offset channel of the cooperating cylinder rolls. So one can Dynamic forces are balanced. With a fixed offset angle of 180 ° and linear arrangement of the cylinders lies for all production rates, i. H. Angular velocities, destructive interference before without an offset angle of Channels must be varied depending on the speed or frequency.

The arrangement of printing unit cylinders of simple scope is particularly advantageous for printed products of smaller and / or variable page size and / or for printing companies with limited space. Compared to producing the same product a double-size press (without gathering) is not a "double" Plate change required. In contrast to a double-size printing press in the collective operation it becomes possible to create an affair from two sides, and thereby creating increased flexibility in the printed product.

The design of all printing unit cylinders with a simple scope allows in comparison Printing units which have one or more cylinders of double circumference much more compact and lightweight design. Are also damaged Rubber blankets to be replaced are smaller and therefore less expensive

The use of printing blankets and printing plates allows the cylinders to be on both sides Stable to store, with a simple, robust and inexpensive construction of the Printing unit cylinder receiving side frame is made possible.

With regard to a robust and simple construction, it is also advantageous if the Parking the printing unit only the transfer cylinders are moved have to. The form cylinders can indeed be spaced apart for the purpose of adjustment Transfer cylinder and, if necessary, ink and, if available, dampening unit can be changed be stored, a turning on and off of the transfer cylinder from each other and from associated forme cylinders, however, is advantageously carried out solely by means of a Movement of the transfer cylinder.

The movement is linear by a specially selected movement in the area of the pressure point Arrangement of the cylinders enables and at the same time switch-on and switch-off devices or - Movements of the forme cylinders avoided. This also contributes to the robust and simple Execution at.

In an advantageous embodiment, the transfer cylinders are in for this purpose Arranged levers which are pivotally mounted eccentrically to the forme cylinder axis. Due to the special position of the pivot points and the size of the eccentric (for Axis of rotation of the forme cylinder) in connection with the selected inclination to the plane the cylinder forming the pressure point or between the web and the plane of the cylinder is a Fast parking of the assigned cylinders or clearing of the web possible. The operational starting and stopping is done only by means of the transfer cylinder, in a preferred embodiment by means of only one actuating movement.

In one possible variant, the transfer cylinders can be in double eccentric bushings be stored, which is almost linear at least in the area close to the pressure point and largely allows movement perpendicular to the plane of the cylinder axes.

Due to the elevators designed as so-called metal printing blankets on the Transfer cylinders will reduce the effective channel width, reducing excitation of vibrations further advantageously reduced and the non-printing area on the cylinders, d. H. the "white border" on the product or the waste paper is reduced.

The execution of the printing unit with cylinders is particularly advantageous Scope and arrangement in one plane, with offset, but mutually channels rolling on one another, and with elevators designed as metal printing blankets on the transfer cylinders.

Especially for washing, changing lifts, etc. cylinders or rollers in printing units from the operating state "pressure on", d. H. a pressure on position against and against each other. The radial movement necessary for this the roller also contains a component of motion in the tangential direction, the Size of the structural design (lever and angle to the nip point) of the Actuator depends. Arises from the adjustment in relation to the operating state a speed difference on the effective lateral surfaces in the nip point, so this implies a due to the surface friction of the roller materials used tangential friction force component which is opposite to the adjustment movement. The Adjustment movement is thus inhibited or its speed is limited.

This is particularly important with printing unit cylinders in the case of so-called "winders", since here The high pressures that occur also result in large frictional forces.

It is therefore advantageous in a method for turning cylinders on and off, one relative tangential velocity in the area close to the contact, d. H. in the field of Nip point of two cylinders or rollers acting together, by conscious, with the Movement correlated rotation or rotation of at least one of the cylinders involved or rolling is reduced. In addition to a reduction in the inhibition in the adjustment also an unnecessarily high load (friction, deformation) of the elevators and / or the Shell surfaces of the cylinders or rollers involved avoided.

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

A first printing unit 01 of a printing press, in particular one Rotary printing machine, has a first cylinder 02, z. B. a forme cylinder 02, and an assigned second cylinder 03, e.g. B. a transfer cylinder 03, (Fig. 1).

In a print-on position AN, their axes of rotation define R02; R03 a level E.

The form cylinder 02 and the transfer cylinder 03 have in their circumference Circumferential direction on the lateral surface at least one fault, for. B. an interruption 04; 06 in the lateral surface effective when unrolling. This interruption 04; 06 may a joint of a leading and a trailing end of one or more Be elevators, for example, by means of magnetic force or cohesive on the Scope are arranged. However, it can also, as in the following Embodiments shown to channels 04; 06 or slots 04; 06 act, which pick up the ends of elevators. The following as channels 04; 06 designated faults are synonymous with other interruptions 04; 06 on the effective surface area, d. H. the outward-facing surface of the with elevators provided cylinder 02; 03.

The forme cylinder 02 and transfer cylinder 03 each have at least two channels 04; 06 (or interruptions 03; 04 etc.). These two channels 04; 06 are in Longitudinal direction of the cylinder 02; 03 in a row, and in the circumferential direction to each other staggered.

Assign the cylinders 02; 03 only a length L02; L03 on which essentially corresponds to two widths of a newspaper page, then only two are in relation to each other Channels 04; offset in the circumferential direction and arranged one behind the other in the longitudinal direction; 06 arranged.

Channels 04; 06 are on the two cylinders 02; 03 they arranged at Rotation of the two cylinders 02; 03 each on one of the channels 06; 04 of each other cylinder 03; 04 unroll. The offset of the channels is preferably 04; 06 each cylinder 02; 03 approx. 180 ° in the circumferential direction. Thus roll after 180 ° Rotation of cylinders 02; 03 at least one pair of channels 04; 06 on each other, while on a longitudinal section a of the cylinder 02; 03 the cylinders 02; 03 undisturbed roll on each other.

The transfer cylinder 01 of the first printing group 01 forms with a third cylinder 07; via a train 08; z. B. a printing material web 08, a printing point 09. This third Cylinder 07 can be used as a second transfer cylinder 07 (FIG. 1) or as a Impression cylinder 07 (Fig. 2), z. B. steel cylinder, or satellite cylinder 07 be executed. The axes of rotation R03 and R07 of those forming the printing point 09 Cylinder 03; 07 span a plane D in the print-on position AN (see Fig. 6).

5, the axes of rotation R02; R03; R07 of the three interacting cylinder 02; 03; 07 during a print-on position ON here together essentially in level E, which in this case with level D coincides, and run parallel to each other (see Fig. 5). He knows Satellite cylinder 07 has two pressure points on its circumference, so a second one cannot illustrated printing unit can also be arranged in the common plane E. It can also define its own level E, which is also assigned to it Level D is different.

As shown in the embodiment of FIG. 1, it acts as the second Transfer cylinder 07 third cylinder 07 with a fourth cylinder 11, in particular a second forme cylinder 11 with an axis of rotation R11, together, and forms a second printing unit 12. The two printing units 01; 12 form one on both Pages 13 simultaneously printing unit 13, a so-called double printing unit 13th

5 all axes of rotation R02; R03; R07; R11 of the four cylinders 02; 03; 07; 11 during printing, d. H. in the pressure-on position AN in the common plane E or D and run parallel to each other. 6 shows a corresponding printing unit 13, a pair of forme and transfer cylinders 02, 03; 11, 07 a level E, and the transfer cylinder 03; 07 which form level D different from levels E.

In the case of the double printing unit 13 (FIG. 1), the cylinders 07; 11 of the second Printing unit 12 channels 04; 06 with those described above for the first printing group 01 Properties with regard to the number and that of the offset to one another. Channels 04; 06 the four cylinders 02; 03; 07; 11 one are now preferably arranged such that two channels 04; 06 two interacting cylinders 02; 03; 07; 11 on top of each other roll.

The forme cylinder 02 and the transfer cylinder 03 have an advantageous design each a length L02; L03, which is four or more widths of a printed page, e.g. B. a newspaper page, e.g. B. 1,100 to 1,800 mm, in particular 1,500 to 1,700 mm and a diameter D02; D03, e.g. B. 130 to 200 mm, in particular. 145 to 185 mm, the extent of which corresponds essentially to the length of a newspaper page, hereinafter "Simple scope" (Fig. 3 and 4). The device is also advantageous for other sizes, in which the ratio between diameter D02; D03 and length L02; L03 of the cylinder 02; 03 less than 0.16, in particular less than 0.12, or even less than or equal to 0.08 is.

In an advantageous embodiment, each of the two cylinders 02; 03 two channels 04; 06 on, which each extend continuously over at least one length, which two Widths corresponds to a newspaper page (Fig. 3).

Each cylinder 02; 03 but also more than two channels 04; 06 may be arranged. In this case, two channels 04; 06 in alignment, or alternately. However, it can for example with four channels 04; 06 the two the end faces of the cylinders 02; 03 adjacent channels 04; 06 in a common escape, and the two "inside" lying channels 04; 06 in a common escape, but in the circumferential direction be arranged offset to the former (Fig. 4).

Are the interruptions 04; 06 actually as channels 04; 06 or slots 04; 06 executed, the channels 04; 06 something longer than the width or double the width of the printed page. Possibly. you can have two in Channels 04; 06 also slightly in the circumferential direction overlap. This is not the case in FIGS. 1 to 4, which are only shown schematically so detailed can be removed.

Particularly advantageous with regard to the excitation or damping by Vibration caused by channel impact is when the channels 04; 06 on the respective cylinder 02; 03; 07; 11 are offset from each other by 180 °. So they roll Channels 04; 06 between the forme cylinders 02; 11 and the transfer cylinders 03; 07 of the two printing units 01; 12 simultaneously and in the area of the same section in Longitudinal direction of the cylinder 02; 03; 07; 11 from; z. B. on the same page, e.g. B. a side I (Fig. 1, 3 and 4) of the double printing unit 13 in one stage of the cycle, and in the another phase on one side II, or with more than two channels 04; 06 per cylinder 02; 03; 07; 11, for example in the area of the center of the cylinder 02; 03; 07; 11th

Due to the offset arrangement of the channels 04; 06 and the unwinding of all channels 04; 06 in the manner described, and in addition, if necessary, the linear arrangement of all cylinders 02; 03; 07; 11 in a plane E, the excitation of vibrations is significantly reduced. Due to the synchronous and possibly symmetrical unwind on the two printing units 01; 12 there is a destructive interference of the suggestions, which when choosing the Offset of channels 04; 06 on the cylinders 02; 03; 07; 11 by 180 ° from the speed the cylinder 02; 03; 07; 11 or the frequency takes place independently.

Are the interruptions 04; 06 actually as channels 04; 06, they are in an advantageous embodiment with a small width gap, for. B. less than or equal to 3 mm, in the area of a lateral surface of the forme cylinder 02; 11 or transfer cylinder 03; 07 executed which ends of one or more elevators, for. B. one or several blankets, on the transfer cylinder 03; 07 or ends of one or several elevators, e.g. B. one or more printing plates on the forme cylinder 02; 11 receives. The elevator on the transfer cylinder 03; 07 is preferably a so-called Metal printing blanket, which on a metallic base plate has ink-bearing coating. In the case of Transfer cylinders 03; 07 for example by clamping and / or tensioning devices and in the case of forme cylinders 02; 11 by clamping devices in the channels 04; 06 held.

In each of the channels 06 of the transfer cylinder 03 there can be a single, continuous one Clamping and / or tensioning device or it can - in the case of more than one Newspaper page widths through continuous channels - several in a row in the longitudinal direction Clamping and / or tensioning devices can be arranged. The channels 04 of the forme cylinder 02, for example, also each have a single one or more Clamping devices on.

Preferably, the forme cylinder 02; 11 as well as in the Channels 06 of the transfer cylinder 03; 07 a "minigap technology" was used, being in a narrow channel 04; 06 with an inclined leading hooking edge leading end inserted, the elevator to cylinder 02; 03; 07; 11 wound up is, the trailing end also in channel 04; 06 is inserted, and the Anti-slip ends, e.g. B. by means of a rotatable spindle or pneumatic device to be clamped.

However, it can also be used both for the elevator on the forme cylinder 02; 11, as well as for the elevator of the transfer cylinder 03; 07 a as narrow slot 04; 06 executed channel 04; 06 arranged without a clamping device be the one that picks up the ends of the lifts. The ends are here, for example by their shape and / or the geometry of the slot in slot 04; 06 held.

The transfer cylinder 03; 07 have z. B. in an advantageous embodiment (Fig. 3) only two elevators offset in the circumferential direction from each other by 180 °, which each have at least one width, which two widths of a newspaper page equivalent. In this case, the elevators or channels 04 of the forme cylinders 02; 11 complementary to this and must either, as shown, two continuous, each a length of two newspaper page widths, channels 04, or in pairs Adjacent and aligned channels 04 each having a length of one Have newspaper page width. In the former case, each actually shows channel 04 executed interruption 04 of the forme cylinder 02; 11 in an advantageous embodiment two Clamping devices each have a length that is essentially a width of one Newspaper page corresponds to.

The forme cylinder 02; 11 are in an advantageous embodiment with four in the longitudinal direction Forme cylinder 02; 11 bendable lifts arranged side by side, which in Circumferential direction a length of slightly above the length of the printed image Newspaper page, and in the longitudinal direction have a width of about one newspaper page. When arranging continuous channels 04 and only one clamping device per channel 04; 06, which has a length of two widths on a newspaper page, is also possible lifts with a width of two newspaper pages, so-called panorama printing plates, raise.

For printing units 01; 12, for which a need of equipping with panoramic printing plates can be excluded, an arrangement can also be advantageous, the each to side I and the "outer" elevators adjacent to side II align and align the "inner" lifts with each other and to the former Are arranged offset by 180 ° (Fig. 4). This highly symmetrical arrangement leaves additionally reduce the risk of vibration excitation in level E or avoid which is caused by the non-simultaneous passage of channels 04; 06 on Side I and Side II can result. This also alternates between side I and side II alternating tensioning and relaxation of the web 08, and thereby caused Swinging of the web 08 can thereby be avoided.

The said arrangement of interruptions 04; 06 on the respective cylinder 02; 03; 07; 11 and between the cylinders 02; 03; 07; 11 and possibly the linear arrangement of the Cylinder 02; 03; 07; 11 are in training also particularly on cylinder 02; 03; 07; 11 to apply, which have a length L02; L03, which essentially the corresponds to six times the width of a newspaper page. However, it can be an advantage here be the transfer cylinder 03; 07 and / or the forme cylinders 02; 11 with one Diameter D02; Execute D03, which results in a scope that in corresponds essentially to twice the length of a newspaper page.

For a technically simple and robust design of the double printing unit 13, the Forme cylinder 02; 11 in an advantageous embodiment with respect to their axes of rotation R02; R11 fixed. For switching the printing units 01; 12 are the Transfer cylinder 03; 07 with respect to their axes of rotation R03; R07 movable executed and are simultaneously from the associated forme cylinder 02; 11 and from interacting transfer cylinder 03; 07 adjustable, or adjustable to this. In this version will only be in normal operation of the press Transfer cylinder 03; 07 moves while the forme cylinder 02; 11 in their fixed, if necessary previously adjusted position remain. The form cylinders 02; 11 however in corresponding devices, e.g. B. in eccentric or double eccentric bushings, in Linear guides or in levers.

The transfer cylinder 03; 07, as shown schematically in FIGS. 5 and 6, movable along a curved path 17. The Stellweg 17 and the Transfer cylinder 03; 07 in a print-down position AB are dashed in Fig. 5 shown.

In the lever 18 shown schematically in FIG. 5, one of the transfer cylinders 03 pivoted about a pivot axis S. The pivot axis S is here z. B. in the level E. The lever 18 has a length between the storage of the Axis of rotation R03; R07 of the transfer cylinder 03; 07 and the pivot axis S which is larger than the distance of the axis of rotation R03; R07 des Transfer cylinder 03; 07 from the axis of rotation R02; R11 of the assigned Forme cylinder 02; 11 in print-on position ON. This means that it is switched off simultaneously of cooperating transfer cylinder 03; 07 and the associated Forme cylinder 02; 11, and vice versa for starting.

However, the pivot axis S can in particular also, as described in more detail below, in otherwise eccentric to the axis of rotation R02; R11 of the assigned Forme cylinder 02; 11, e.g. B. at a distance from the plane E. Warehousing in a lever 18 is preferably on side I and on side II of the Double printing unit 13.

In a further embodiment, not shown, the travel path 17 z. B. through the storage of the transfer cylinder 03; 07 in not shown Eccentric bushings, especially in double eccentric bushings. With Double eccentric bushes can be largely used in the ON position linear travel, but in the area farther from the pressure point 09, if necessary Generate curved travel 17, which faster or larger parking the transfer cylinder 03; 07 of the cooperating transfer cylinder 07; 03 as from the associated forme cylinder 02; 11 or vice versa allowed. Also for them The use of eccentrics is the storage on side I and on side II of the Double printing unit 13 is an advantage.

5 and 6 is also the course of the web 08 through the in the print-on position ON located printing point 09 shown. The plane E of the double printing unit 13 (FIG. 5) or the respective printing group 01; 12 (Fig. 5, 6) and cut the plane of the web 08 in an advantageous embodiment at an angle α of 70 ° to 85 °. Assign the Transfer cylinder 03; 07 has a circumference which is approximately one Newspaper page corresponds, the angle α z. B. between 75 ° and 80 °, preferably about 77 °, the transfer cylinder 03; 07, however, to an extent which is approximately corresponds to the length of two newspaper pages, the angle α z. B between 80 ° and 85 °, preferably approx. 83 °. This choice of the angle α contributes to the one hand safe and quick release of the train 08 and / or the parking of the Transfer cylinder 03; 07 from each other with minimized travel 17, and minimized on the other hand negative influences on the printing result, which are caused by the dimension of a partial wrapping of the or the transfer cylinder 03; 07 decisive is influenced (duplication, lubrication, etc.).

At least one of the transfer cylinders 03; 07 is in an advantageous embodiment adjustable so far that the retracted web 08 during the printing operation by means of other printing units can be guided through the printing point 09 without contact.

The double printing unit 13 (here in a linear design) is multiple, as in FIG. 7 shown for example twice, in a printing unit 19, for. B. a so-called. H printing unit 19, can be used in a common side frame 20. In Fig. 7 was on the separate designation of the parts identical to the upper double printing unit 13 for the double printing unit 13 located at the bottom is omitted. When all cylinders are arranged 02; 03; 07; 11 with a circumference which is essentially a length of one Corresponds to newspaper page, can be in terms of space, d. H. at a height h of the printing unit 19 save on. Of course, this also applies to individual printing units 01; 12, for Double printing units 13 and for differently configured printing units, which several Printing units 01; 12 have. However, the priority can instead of saving Height h also with improved accessibility of the cylinders 02; 03; 07; 11, e.g. B. for the purpose of changing lifts, cleaning work and washing, maintenance etc.

The pressure on or off position ON; AB is for clarification in all figures shown exaggerated. Fig. 7 indicates the transfer cylinder 03; 07 in one second possible location along the actuating path 17, for example here upper double printing unit 13, z. B. for the purpose of printing form change, in the print-down position AB, and the lower double printing unit 13, z. B. for continued printing, in the Pressure ON position is operated.

In an advantageous embodiment, each of the printing units 01; 12 at least one own, drive motor 14 for the rotary drive of the cylinders 02; 03; 07; 11 on. The drive motor 14 is an electric motor, in particular an asynchronous motor, Synchronous motor or designed as a DC motor.

The Eccentricity e-S is in the position of the transfer cylinder 02; 03; 07; 11, d. H. the Axes of rotation R03; R07 are in the above Level D, oriented so that an angle ε-S between the plane D of the cylinder 03; 07 and the Connection plane V of the pivot axis S and the axis of rotation R02; R11 between 25 ° and 65 °, advantageously between 32 ° and 55 °, in particular between 38 ° and 52 °, the pivot axis S preferably in the range of an obtuse angle β between level D and the incoming or outgoing web 08, and further from the printing point 09 is spaced as the axis of rotation R02; R11 of the associated forme cylinder 02; 11th With vertical, and, except for one possibly caused by partial wrapping Offset, straight web run and an angle of 77 ° between the plane D and the plane Bahn 08, the eccentric e-S z. B. an angle of 12 ° to 52 °, advantageously 19 ° up to 42 °, in particular 25 ° to 37 ° to the horizontal H.

Ideally, d. H. with never changing conditions and tolerance-free production, the arrangement as described so far is sufficient without further adjustment mechanisms Requirements for starting and stopping the printing units 01; 12 or des Double printing unit 13.

However, to compensate for any manufacturing tolerances that may arise and / or a Basic settings for the elevators, substrates, etc. are other Adjustment options given for adjustment purposes:

The axis of rotation R02; R11 of the forme cylinder 02; 11 is adjustable, e.g. B. also eccentric to its attachment to the side frame 20, here to a bore 49, stored. In the present case, a pin 51 of the forme cylinder 02; 11 in one Eccentric bearing 52 or an eccentric bearing bush 52 arranged in the Bore 49 is pivotally mounted.

A pivot axis S51 of the forme cylinder 02; 11 is about an eccentricity of 5 to 15 mm, in particular about 7 to 12 mm eccentric to the axis of rotation R02; R11 des Forme cylinder 02; 11 and is located outside of level E.

The eccentricity e-S51 is in the position of shape and assigned Transfer cylinder 02, 03; 11, 07, d. H. the axes of rotation R02, R03 or R11, R07 lie in the plane E, oriented so that an angle ε-S51 between the plane E of the Pair of cylinders 02, 03 or 11, 07 and a connecting plane of the pivot axis S51 and the axis of rotation R02; R11 of the forme cylinder 02; 11 between 25 ° and 65 °, advantageously between 32 ° and 55 °, in particular between 38 ° and 52 °. The Pivot axis S5 is preferably in a half-plane, which is more distant from Axis of rotation R03; R07 of the assigned transfer cylinder 03; 07 than that Axis of rotation R02; R11 of the associated forme cylinder 02; 11 lies.

The swivel axis S51 for the eccentric mounting of the forme cylinder 02; 11 falls in 8 with the pivot axis S of the lever 18 together.

The coincidence of the pivot axis S and S51 is not mandatory, however appropriate. In particular by the stationary with respect to the side frame 20 Swivel axis S, which by pivoting the forme cylinder 02; 11 not affected allows simple and exact adjustment. Basically, the lever 18 could too on an eccentric flange of the bearing bush 53 receiving the pins 51 be arranged, which, however, a simultaneous adjustment of the distances when twisting between form- 02; 11 and transfer cylinder 03; 07 and between the Transfer cylinders 03; 07 would have resulted.

In an advantageous embodiment, the two pivot axes S51 are in the pressure-on position AN (and / or S) and S23 of a pair of forme and transfer cylinders 02, 03; 11, 07 arranged on two different sides of level E.

You are e.g. B. also eccentrically in the assigned Lever 18 stored. An eccentricity e-S23 of a pivot axis S-23 to the axis of rotation R03; R07 of the transfer cylinder 03; 07 is between 1 and 4 mm, in particular approx. 2 mm. The eccentricity e-S23 is in the position where the pressure point 09 forms Cylinder 03; 07, d. H. the axes of rotation R03; R07 are on level D, oriented so that an angle ε-S23 between the plane D and the connecting plane of the Swivel axis S-23 and the rotation axis R07 (R03) between 70 ° and 110 °, advantageously between 80 ° and 100 °, in particular between 85 ° and 95 °. For example the angle ε-S23 should be approx. 90 °.

FIG. 9 shows an embodiment according to FIG. 8 in a representation of a section given along the plane E. The pin 51 of the forme cylinder 02; 07 are in Bear 54, e.g. B. rolling bearings 54, rotatably mounted. To a setting or a To be able to make corrections to the page register is made possible in an advantageous manner Execution of this bearing 54 or an additional thrust bearing, not shown Movement of the forme cylinder 02; 11 or its pin 51 in the axial direction. The Bearings 54 are arranged in the eccentric bearing 52 or in the eccentric bearing bush 52, which in turn is arranged pivotably in the bore 49 in the side frame 20. It can in addition to the eccentric bearing bush 52 and the bearing 54 Bearing rings and plain or roller bearings arranged between bore 49 and pin 51 his. The lever 18 is on a to the forme cylinder 02; 07 out of the side frame 20 protruding part of the bearing bush 52, and pivotally mounted relative to this. The Lever 18 takes in its end remote from the pivot axis S the pin 23 of the Transfer cylinder 03; 07 on which rotates in a bearing 56, and this in Case of the transfer cylinder 07, pivotable in one around the pivot axis S-23 Eccentric bearing 57 or in an eccentric bearing bush 57 is arranged. A Such pivotable bearing bush 57 can, if necessary, also for both Transfer cylinder 03; 07 be arranged.

The side frame advantageously has, at least on one drive side of the printing press 20 recesses 58 in which the pin 23 of the transfer cylinder 03; 07 are pivotable. The actuating means 46; 53 or drive means 44 are not shown in FIG. 8 shown.

The rotary drive of the cylinders 02; 03; 07; 11 takes place by means of separate mechanically from the drive of the other cylinder 02; 03; 07; 11 independent Drive motors 14, which are preferably arranged fixed to the frame. The latter has the Advantage that the drive motors 10 do not have to be moved.

To the pivoting movement of the transfer cylinder 03; To balance 07 is between Transfer cylinder and drive motor 10 an angular and offset compensating Coupling 61 arranged. This can be used as a double joint 61 or else advantageously Design as an all-metal coupling 61 with two torsionally rigid but axially deformable Lamella packs are executed. The all-metal coupling 61 can at the same time Compensate for misalignment and the resulting change in length. It is essential that the rotational movement is transmitted without play.

The drive of the forme cylinder 02; 11 has between pin 51 and drive motor 14 a clutch 62, which has at least one axial relative movement between Cylinder 02; 11 and drive motor 14 takes. In order to also tolerate manufacturing tolerances and required movements of the forme cylinder 02; 11 for adjustment purposes, is also the clutch 62 as at least slight angle and offset compensating Coupling 62 executed. This is also in an advantageous embodiment All-metal clutch 62 with two torsionally rigid but axially deformable plate packs executed. The axial movement is due to the form-fitting in the axial direction with the Pin 51 or a shaft of the drive motor 14 connected plate packs added.

In an advantageous development is between each of the drive motors 14 and cylinder 02 to be driven; 03; 07; 11 a transmission 63 interposed. This Gear 63 can be connected to the drive motor 14 attachment gear 63, e.g. B. a Planetary gear 63 be. However, it can also be used as another reduction gear 63, e.g. B. from pinion or belt and drive wheel. One is advantageous individual encapsulation of the gearbox 63, which is particularly the case in the case of an auxiliary transmission 63 can be implemented in a simple manner. The lubricant spaces created in this way are spatial narrowly limited and prevent pollution of neighboring machine parts as well contribute to increasing the quality of the product.

In the case of those indicated schematically in FIG. 6 in the lower double printing unit 13 drives in pairs of cylinders 02; 03; 07; 11 is driven on the forme cylinder 02; 11 - e.g. B. via the attachment gear 63 or a pinion on a drive wheel of the Forme cylinder 02; 11. It is advantageous here to train those working together Drive wheels between forme and transfer cylinders 02, 03; 11, 07 each with one Straight teeth. The latter also applies to a pinion which may be arranged between Drive motor 14 and the drive wheel of the forme cylinder 02; 11. One of the above separate In this case, encapsulation extends around the paired drive of two cylinders 02, 03; 11, 07

In a variant shown in FIGS. 10 and 11, a paired drive can also be from Drive motor (possibly via further gear parts, not shown) by a pinion 59 a drive wheel 61 of the transfer cylinder 03; 07 if, for example, a special torque flow is to be achieved.

An axis of rotation R59 of the pinion 59 is then preferably fixed to the frame in this way arranged that one of the rotation axis R59 of the pinion 59 and the Pivot axis S of the lever 18 defined straight line G1 with one of the pivot axis S of the lever 18 and the axis of rotation R03; R07 of the transfer cylinder 03; 07 specified plane E18 an opening angle η in the range of + 20 ° to - 20 ° includes.

In a further development, one of the axes of rotation R02; R11 des assigned forme cylinder 02; 11 and the axis of rotation R59 of the pinion 59 straight line G2 with the axis of rotation R59 of the pinion 59 and the Pivot axis S of the lever 18 defined straight line G1 an opening angle λ im Range from 160 ° to 200 °.

The aforementioned statements on the drive and for pivoting the Transfer cylinder 03; 07 and the execution of the lever 18 are on printing units apply in which the cylinder 02; 03; 07; 11 not all of the same scope or Have diameter (Fig. 12). In particular, this can Forme cylinder 02; 11 have a circumference U, which in the circumferential direction Pressure side, e.g. B. the long side of a newspaper page has (in the following "Single circumference"). The cooperating transfer cylinder 03; 07 z. B. one Circumference or diameter, which is an integer multiple (greater than 1) that of the forme cylinder 02; 11 corresponds to d. H. he has z. B. a scope of two or even three printed pages in newspaper format (or on other formats adjusted accordingly).

If the printing point is 03; 07 and a z. B. as Satellite cylinder 07; 03 executed impression cylinder 07; 03 formed, so can also forme and transfer cylinder 02; 11; 03; 07 have a simple scope and the associated impression cylinder 07; 03 be made many times larger.

The training mentioned also advantageously increases Rigidity of the printing unit reached. This is particularly beneficial in connection with Cylinders 02; 11; 03; 07, which have a length of at least four or even six standing printed pages, especially newspaper pages, corresponds.

The execution of the cylinder 02; 03; 07; 11 double width and - at least the forme cylinders 02; 11 - with "single scope" enables in contrast to printing presses with double Scope and simple width a significantly higher product variability. The maximal The number of possible printed pages is the same, but in the case of single-width Printing units 01; 12 double scope in the collection plant in two different "Books" or "booklet". In the present case the double-wide printing units 01; 12 After printing, the (double-wide) webs 08 become longitudinal cut. In order to achieve a maximum stapling strength, one or more Partial webs in the so-called folded superstructure or reversible deck guided one above the other and z. B. on folded into a booklet using a folder without a collection company. Are such strengths not necessary, some partial webs can be overlaid, others however be guided together on a second former and / or folder. It can but also two products of the same thickness without being transferred to two folders be led. There is therefore a variable strength of two different products. In the case of a double folder or two folders, there are at least two Depending on the arrangement, the two booklets or Products next to or on top of each other to one side of the printing press, or to the on both sides.

The double-width printing press of simple size has a high degree of variability especially in the grading of the possible page numbers in the product, in the so-called "Escapade". While the strength per booklet (layer) for the printing press with double Scope and simple width in the collection operation (i.e. maximum product strength) only can be varied in steps of four printed pages, the double width described Printing machine of simple scope a "fling" from two sides (z. B. in Newspaper printing). The product strength and especially the "distribution" of the printed pages on different issues of the overall product or products is considerably more flexible.

After the web 08 is cut lengthwise, the partial web is either on one different folding former and / or folder for the corresponding partial web led, or it is turned to the escape of the latter. I.e. in the second The partial web falls before, during or after turning, but before merging with the "straight tracks", brought into the correct longitudinal or cutting register. This is in dependence on the channels 04; 06 one Cylinder 02; 03; 07; 11 in an advantageous embodiment by appropriate execution of Turning decks (e.g. preset distances between the bars or the path sections) considered. The fine adjustment or control is made with the travel ranges of the Cutting register regulation for the relevant partial web and / or partial web strand made to partial lanes of two different running levels if necessary to bring each other in register.

The forme cylinder 02; 11 is now in the circumferential direction with and in the longitudinal direction At least four standing printed pages can be loaded in broadsheet format (Fig. 13). Alternatively, this forme cylinder 02; 11 also optionally in the circumferential direction with two and in the longitudinal direction with at least four lying printed pages in tabloid format (Fig. 14) or in the circumferential direction with two and in the longitudinal direction with at least eight standing printed pages in book format (Fig. 15) or in the circumferential direction with four and in Longitudinal direction with at least four lying printed pages in book format (Fig. 16) by means of one and its longitudinal direction in the circumferential direction of the forme cylinder 03 at least one flexible printing plate that can be arranged on this.

By means of the double-width printing press and at least the forme cylinders 02; 11 simple scope are thus depending on the occupancy of the forme cylinder 02; 11 with lying Tabloid pages or standing newspaper, especially broadsheet pages, with lying or standing book pages different products depending on the used Width of the web 08 can be produced:
