Printing machine and a method for handling at least two cylinders of a printing unit of a printing press

The invention relates to a printing machine according to the preamble of claim 1 and a method for handling at least two cylinders of a printing unit of a printing press according to the preamble of claim 13.

Rotary printing machines operate on a rotary printing principle, such as flexographic printing, offset printing, high-pressure, intaglio printing, etc., in which a printing original of the printing image to be printed is introduced in a lateral surface of one or more forme cylinders or as a pressure plate is mounted on the lateral surface of a forme cylinder, and during the Printing process via an unwinding of the forme cylinder on its outer surface, the print image either directly or via downstream

Transfer cylinder is transferred to a substrate. In order to maintain a high print quality at the same time essentially independently of the production speed and of other external influences, it is also frequently provided to operate the pressure rollers by means of a tempering device at a certain adjustable temperature by flowing through the pressure rollers, for example, by a cooling liquid.

In addition, it is necessary, in particular in the printing of sheet-like printing material to make a print length of a printed image for different print jobs variable at least in steps, whereby, for example, in

Packaging printing creates the opportunity to design different sized packaging. As in particular in the packaging printing mentioned a variety

different types of packaging such as tubular bag packaging or

Folding boxes are used with different shapes and sizes, it is required such rotary printing press manufacturers so that different form cylinder and / or transfer cylinder and / or

Cliché rollers can be used with different enclosures in the printing press.

The change of the different circumference of the cylinder can be made, for example, by exchanging, on a cylinder core with a certain diameter pushed and / or windable, sleeves or so-called sleeves with different outer diameters or by replacement of complete cylinder. This is done, for example, manually by an operator, in which case the cylinders must be turned off from each other and for the replacement of cylinders with a different diameter, the distance between the cylinders must be such that even cylinders with a maximum diameter can be easily replaced. Replaceable sleeves are known, but usually have the disadvantage that a temperature control of the lateral surface of the sleeves is not possible for all sleeves equally, since usually only the cylinder is mounted on the corresponding sleeve, via means for

Temperature control and then the corresponding surface temperatures of the cylinder are transmitted through the sleeve to ultimately set a surface temperature of the lateral surface of the sleeve. Different sized sleeves show different characteristics like heat conductivity or

Heat capacity.

For this purpose, the cylinders can be mounted, for example, in eccentric bushings, which can be pivoted by means of a suitable drive. In this case, only a limited pivoting of adjacent cylinders to each other on one

Circular arc possible, which requires a costly readjustment of the cylinder to each other in an exchange of cylinders of a first diameter against cylinders of a second diameter. It is also known to adjust the position of the cylinder to each other by means of a respective linear drive, whereby the cylinder and in particular associated

Bearing receptacles of the cylinder can each be moved to each other. In this case, a respective linear drive must be assigned to each moving along a particular direction, in particular shifting cylinder, resulting in a complex structure with corresponding costs.

An exact match of a print image on the front and back of a printed substrate printed on both sides is called register (DIN 16500-2). in the

Multi-color printing is referred to as the Passer (DIN 16500-2), when the individual print images of the different colors are combined exactly to a picture. In connection with the register or the passer when printing in multi-color rotary printing presses are various correction requirements and

Correction methods known. A correction of the page register or Seitenpassers, so a shift of the print image in a direction transverse to a transport direction of a printing substrate to be printed, for example, by moving,

For example, moving a forme cylinder can be achieved in the direction of its axis of rotation. The circumferential register or the peripheral register, so a shift of the print image in one direction along the transport direction of the printing material to be printed, can be adapted to each other for example by changing the phase position of the form cylinder involved. Furthermore, it may be necessary, the

Diagonal register or the diagonal register, so an inclination of the printed image to correct, for example, when printing plates are not aligned on a plate cylinder in the appropriate angle and thereby skew the printed image of the corresponding color is formed on the substrate. For this purpose, for example in rotary printing presses, usually the form cylinder is tilted so that its axis of rotation is no longer to the axis of rotation of the

Transfer cylinder is parallel. The following is for the sake of simplicity only of page perimeter or diagonal register to be the talk, but it is always equally equally the page - perimeter or diagonally meant.

DE 199 37 783 A1, DE 101 03 632 A1, DE 10 2006 020 957 A1 and DE 199 37 796 A1 each disclose a positioning device of at least two cylinders of a printing unit of a printing machine, wherein the positioning device has at least one rail arrangement and wherein the rail assembly comprises at least one rail and at least two carriages, and wherein one each, with a

The invention has for its object to provide a printing machine and a method for handling at least two cylinders of a printing unit of a printing press. The object is achieved by the features of claim 1 and the features of claim 13.

The achievable with the invention advantages are in particular that with only one handling device, two cylinders of a printing unit at the same time from a first position in which they are in contact with the same bearing receptacles with which they are in contact in a printing operation, moved into a removal position can be, whereby a removal of the cylinder and in particular a simultaneous removal of multiple cylinders is simplified. This can also be done on relative

inaccessible locations within a printing press arranged cylinder

exchanged and in particular be replaced fully automatically, which is particularly advantageous, for example, in a format change of an offset printing machine.

Another advantage is that, in spite of the handling device suitable for exchanging at least two cylinders, it is also possible to replace only one cylinder, which may save unnecessary work steps.

Another advantage is that by being able to move the cylinders in two different directions, one direction of which has a component in the horizontal direction which is larger than a possible component in the vertical direction and of which the other direction is one Component in the vertical direction, which is greater than a possible component in the horizontal direction, a greater flexibility is achieved and the handling device is particularly suitable for different printing units, in contrast to devices that

For example, cylinder lift vertically upward only from appropriate recordings. An advantage of an embodiment is that a cylinder can be replaced by different, relatively displaceable lifting arms and the other can remain arranged in its bearing receptacles and that it can be chosen freely, which cylinder is replaced and which not and that with the same handling device If required, several cylinders can be exchanged at once.

An advantage of another embodiment is that by dispensing with relatively movable lifting arms costs can be saved and that then indeed always lifted several cylinders from their bearing seats and moved to another position, but by appropriate selection in a further processing unnecessarily moved cylinder can be moved back without additional effort and re-installed in the printing unit.

A further advantage is that a fully automatic movement of the cylinder between two positions is made possible by own drives for each direction of movement and by a preferably connected to the drives machine control and thereby in conjunction with other devices a fully automatic change of any number of cylinders and in particular a forme cylinder and at the same time an associated transfer cylinder is made possible.

A further advantage is that the handling device is adapted to positions and preferably to service positions and removal positions of cylinders, which are independent of circling of the cylinders. This is possible because they are positions where the cylinders are offset from each other by other means such as carriages and rails. In this way it is easily possible with the handling device to exchange cylinders of one circumference for cylinders of a different circumference, without the handling device would have to be adjusted. This increases the flexibility of the printing machine and facilitates a fully automatic Cylinder change.

Another advantage is that by corresponding layers, the

Handling device can take, the handling device is positioned in a particularly space-saving location, as long as it is out of order.

Another advantage is that flexible mobility of the

Handling device in several directions, in particular a handling of completely or partially superimposed cylinders is made possible. A transfer between devices is not necessary, so that a corresponding method can proceed as simply as possible and a corresponding device can be designed as simple as possible.

Another advantage is that fewer drives are required by a common mobility of cylinder cylinders associated with different cylinders, as if cylinder holders were independently movable.

A printing press designed as a rotary offset printing press has at least one printing unit designed as a rotary offset printing unit. This printing unit has at least one designed as a forme cylinder 01 cylinder 01, the plate cylinder 01 may be formed and at least one designed as a pressure cylinder 02 cylinder 02 or impression cylinder 02 and optionally at least one as

Transfer cylinder 03 trained cylinder 03, which may be a blanket cylinder 03, on. If the printing unit is designed as a rotary offset printing unit, form cylinder 01, transfer cylinder 03 and impression cylinder 02 operate in one

Printing operation together in a known manner, so that the cylinder 01; 02; 03 are in direct contact with each other during printing operation at least in pairs. In the printing operation, all devices are in a production position. The forme cylinder 01 is inked by an inking unit with printing ink corresponding to a printed image to be printed. The selectively arranged on the forme cylinder 01 printing ink is transmitted by rolling contact on the transfer cylinder 03 and from there also transmitted by means of rolling contact on a substrate 04, which is pressed between the transfer cylinder 03 and the pressed thereon

Counter-pressure cylinder 02 is passed. The printing material 04 may be, for example, web-shaped or arcuate, and all possible printing materials 04 such as paper, cardboard, cardboard, textiles, plastic or metal may be printed.

The invention can also be applied to other printing processes such as high-pressure, flexographic printing or gravure printing. In addition, when it is said that ink is transferred, as well as a transfer of paints is included and therefore the invention also applies to painting equipment.

In one embodiment of such a printing press, a counter-pressure cylinder 02, a transfer cylinder 03 and a forme cylinder 01 are arranged. The forme cylinder 01 is in rolling contact with at least one, but preferably two inking rollers 06. The at least one inking roller 06 is in rolling contact with an inking roller 07, wherein this inking roller 07 is preferably designed as an anilox roller 07. The ink roller 07 is in contact with a color source 08, wherein the color source 08 in the case that the ink roller 07 is formed as an anilox roller 07, preferably as Chamber doctor 08 is formed. There are also other embodiments conceivable in which, for example, the color source 08 is designed as a color box 08 and the

Ink roller 07 as at least partially in the ink of the ink fountain 08th

immersed Farbduktor 07 is formed. Furthermore, it is possible that even more rollers between the forme cylinder 01 and the ink roller 07 are arranged and it is also possible that further rollers 1 1; 12 are arranged, which are not on a direct Farbtransportweg between ink roller 07 and forme cylinder 01, but for example as Farbreibwalzen 12 are formed and a homogenization of a color film are used, which is on components of the printing unit and in particular on the forme cylinder 01 (Fig. 1) , It is also possible, at least one dampening unit with corresponding dampening rollers and at least one corresponding

To arrange dampening solution source, in the preferred here described

However, this is not the case.

The forme cylinder 01 and the transfer cylinder 03 are preferably arranged one above the other, preferably so that in the printing operation an axis of rotation 13; 14 one of the two cylinders 01; 03 in the vertical direction directly above or below a component of another of the two cylinders 01; 03 is arranged, more preferably such that at least the rotational axis 13 of the forme cylinder 01 and the axis of rotation 14 of

Transfer cylinder 03 lie in a common vertical plane. One

Substrate 04 is preferably transported horizontally, at least at the point where it is in contact with the transfer cylinder 03. The following is from this

Arrangement assumed, but the invention can also be transferred to embodiments in which such a plane is not vertical and / or the substrate 04 is not transported horizontally and should therefore not be limited to this particular arrangement. In addition, the paraphrasing that at least the rotation axes 13; 14 are in a common plane also include the case that at least the two axes of rotation 13; 14 are not exactly parallel and therefore not mathematically exactly in a plane, for example, because one of the axes of rotation 13; 14 slightly skewed to the other due to a diagonal register setting

Rotation axis 13; 14 lies.

Preferably, at least one roller and / or a cylinder 01; 02; 03 exchangeable, more preferably, all rollers and cylinders 01; 02; This makes it possible, for example, to use different forme cylinders 01, which differ on the one hand in the printed image to be printed, but on the other hand can also have a different circumference and thus the possibility for Open printing in different formats, without leaving space on, for example, a web-shaped substrate 04 unnecessarily unprinted. Thus, a smaller print image can be printed with a forme cylinder 01 smaller circumference, while a web-shaped substrate 04 and a constant format of the forme cylinder 01 with a smaller print image would produce a larger waste. Of the

Transfer cylinder 03 is also exchanged in the case of an exchange of the forme cylinder 01, since the circumference of forme cylinder 01 and transfer cylinder 03 must match or at least have to be in an integer ratio.

To form cylinder 01 and transfer cylinder 03 different formats in the

To use printing press, the press has different

Properties and devices.

The printing machine preferably has at least one positioning device 101 for at least the forme cylinder 01 and the transfer cylinder 03, since a

Positioning the rotation axes 13; 14 of the forme cylinder 01 and the

Transfer cylinder 03 must be adapted to the diameter when these cylinders 01; 03 are exchanged for those with other enclosures. The

Positioning device 101 thus serves, despite different usable scope of the cylinder 01; 03 Distances and gaps between forme cylinder 01, transfer cylinder 03 and impression cylinder 02 to optimize.

To cylinder 01; 02; 03 and / or to replace rollers, they are preferably by means of bearing receivers 32, which are preferably designed as a folding bearing 32 and more preferably designed as a controllable quick-lock bearings 32, rotatably fixed in the printing machine. Such quick-lock bearings 32 ensure a safe and quick replacement of rollers and / or cylinders 01; 02; 03. For a mechanical replacement of rollers and / or cylinders 01; 02; 03 are preferably controllable

Quick locking bearing 32 arranged, since in this way such an exchange can take place automatically and thus accurately and quickly and operating personnel no danger is exposed to a handling of sometimes more than 100 kg heavy components of the printing press. Problems with not quite open folding bearings 32 are reduced or completely avoided by a machine control and preferably in conjunction with corresponding sensors.

At least one cylinder 01; 02; 03 is in the printing press at its two ends with respect to its axis of rotation 13; 14 stored. These are for example

Cylinder pin 17 of the cylinder 01; 02; 03 held in bearing receivers 32. The

Bearing receptacles 32 can and manually and / or automatically open or

closed and / or locked or unlocked. As a result, the at least one cylinder 01; 02; 03 are fixed rotatably in a certain predetermined position. In this case, both cylindrical pins 17 each have at least one preferably designed as a rolling bearing 19 bearing 19, for example, a ball bearing 19 or a roller bearing 19, the outer, fixed in the printing operation immovable component, such as outer ring, fixed in each case a bearing receptacle 32, for example, can be clamped. In this way, the corresponding cylinder 01; 02; 03 about a fixed axis of rotation 13; 14 rotate. The bearing receptacles 32 are preferably arranged so that they by means of one and preferably a plurality of corresponding adjusting devices in directions perpendicular to the axis of rotation 13; 14 of the cylinder 01; 03 can be moved. As a result, changes in a diagonal register can be made depending on the adjusting device and / or an entire cylinder 01; 03 moves, in particular be moved so that, for example, a distance to another cylinder 01; 02; 03 or a contact pressure between cylinders 01; 02; 03 changes. As adjusting eccentric bushings or preferred

Linear adjustment used. Whenever we talk about shifts below, it is understood that they are general movements, for example

Pulling movements are just as suitable, without this being explicitly mentioned.

At least one adjusting device preferably has frame-fixed strips 23; 24 or rails 23; 24 or guide rails 23; 24 or guides 23; 24, in which, for example, at least one carriage 27; 28 is mounted movably via sliding elements 26. The at least one carriage 27; 28 has at least one bearing receptacle 32 in which at least one, with the cylinder pin 17 each of a cylinder 01; 02; 03 firmly connected, roller bearing 19 is arranged. By means of corresponding adjusting devices and, if appropriate, corresponding drives, it is thereby possible to move the cylinder 01; 02; 03 depending on the number and design of the adjustment in different

To shift directions and thus distances between cylinders 01; 02; 03 and / or set rollers. This is preferably possible under machine control. A displacement of the cylinder 01; 02; 03 along its axis of rotation 13; 14 is not possible.

For an exchange of rollers and / or cylinders 01; 02; 03 is preferably at least one handling device 301 and / or a cylinder changing device is provided, which are more preferably in a position, machine-controlled and possible without intervention of an operator rollers and / or cylinder 01; 02; 03 expand and / or install. It should be noted that via an exchange of rollers and / or cylinders 01; 02; 03 can be applied accordingly for a single expansion or a single installation of one or more corresponding components. The at least one handling device 301 thus serves the purpose of exchanged rollers and / or cylinder 01; 02; 03, remove from the printing press and replace it with others if necessary. In this case, various embodiments are conceivable, for example, at least one

Handling device 301 at least one lifting arm 327; 328 having a transport of the rollers and / or cylinder 01; 02; 03 by a series of vertical and / or horizontal movement steps from the printing press in at least one camp or at least one trolley lifts or it can at least one

Cylinder changing device have at least one swivel arm, the rollers and / or cylinder 01; 02; 03 by pivoting movements between at least one position within the printing press and at least one position, for example, on or in a transport device, for example, below the printing machine and / or can pivot back. Such a transport cart or such a transport device can be designed so that it has, for example, a storage position or a plurality of storage positions and thus rollers and / or cylinder 01; 02; 03 can and optionally transport machine-controlled between different locations, which can be selected at each relevant location, which storage position is released for loading or unloading.

Since both each forme cylinder 01 and each transfer cylinder 03 are preferably each provided with their own drive 16, for example in the form of a motor 16, this drive 16 must be in the event of a change of the corresponding cylinder 01; 03 are taken into account. The drives 16, which may be formed, for example, as position-controlled synchronous motors 16 with permanent magnets, are preferably coaxial with the cylinders 01; 03 arranged. Preferably, the motors 16 remain during a change of the cylinder 01; 03 stationary at their occupied in printing operation place, for example on a side frame of the printing press. For this purpose, a coupling device between cylinder 01; 03 and motor 16 are separable. Preferably, such a separation is at least also machine-controlled feasible. Further preferred For example, the printing machine has at least one page register adjustment device 602, while a peripheral register is at least provided by the separate drive 16

Form cylinder 01 requires no additional mechanical components. The

Seitenregistereinstellvorrichtung 602 is preferably arranged cooperatively with the coupling between the motor 16 and forme cylinder 01, since after a change of the forme cylinder 01 usually a new setting of the side reg ister required.

At least the forme cylinder 01 or the transfer cylinder 03 or both the forme cylinder 01 and the transfer cylinder 03 have at least one but preferably two diagonal register adjustment devices each.

In principle, it is not only possible to exchange forme cylinders 01 and / or transfer cylinders 03 of a first circumference for those having a different, second circumference, but it is also possible to use corresponding cylinders 01; 03 with different lifts or sleeves, so-called sleeves to provide, each one the same

Inner diameter and different outer diameter. These sleeves are placed on a cylinder 01; 03 pushed and fixed it, so are with a single such cylinder 01; 03 different effective circumferential lengths for different printing operations possible.

For a consistent and high print quality, it is provided that at least the forme cylinder 01 and / or the transfer cylinder 03 are designed to be temperable in order to control and / or regulate a respective surface temperature of at least the lateral surface. For this purpose, at least the forme cylinder 01 and / or the transfer cylinder 03 with an inflow and an outflow and a

durchströmbaren component provided so that this of a liquid

Temperature control are flowed through and can be kept in this way in the printing operation of at least the forme cylinder 01 and / or the transfer cylinder 03 on its lateral surface at a constant temperature. In addition, components of the printing unit, which are in the printing operation with adjustable cylinders 01; 03 in contact are also movably arranged, as at a

Format change and in particular with a circumferential change of the cylinder 01; 03, these components must be at least partially adjusted in their positioning. For example, it must be ensured that an inking roller 06 always has the same distance or contact pressure to the forme cylinder 01, regardless of the circumference of the forme cylinder 01. The same applies to others

Contact points at which one of the cylinders 01; 03 is involved.

It should be noted that the term "parallel" in previous and in the following is to be understood as both parallel and antiparallel.

To work with cylinders 01; 02; 03 to be able to print different circumference and optionally cylinder 01; 02; 03 to be able to replace wholly or partially or at least be able to turn off each other, the bearing seats 32 are at least one cylinder 01; 02; 03 and preferably at least the forme cylinder 01 and the transfer cylinder 03 can be arranged by means of at least one positioning device 101 at different positions. Such a positioning device 101 has at least one, and preferably a plurality of parallel, as guide rails 23; 24 or rails 23; 24 trained strips 23; 24 and for everyone by means of

Positioning device 101 positionable cylinder 01; 02; 03 at least one carriage 27; 28 and preferably each cylinder pin 17 a slide 27; 28 on. The

Guide rails 23; 24 may have at least on one side, for example, the shape of dovetail guides. In the figures are simpler

Embodiments with a substantially triangular cross section dargerstellt. Each positionable by the positioning 101 cylinder 01; 02; 03 is thus preferred with its two cylindrical pins 17 on a respective carriage 27; 28 disposed along one or more guide rails 23; 24 movable is arranged. Preferably, the guide rails 23; 24 each of a plurality of carriages 27; 28 shared, corresponding to several cylinders 01; 02; 03 are assigned, so that preferably only two rail assemblies are required for at least one printing unit, each having two parallel rails 23; 24, between which carriage 27; 28 are arranged movable.

A schematic representation of a positioning device 101 can also be seen in FIG. The positioning device 101 in this case, for example, a

Rail arrangement, which at least one and preferably at least two mutually parallel rails 23; 24, each having attached thereto or formed as part of its running rails 102, 103. Between and / or on the rails 23; 24 are different carriages 27; 28 arranged, which at their, the runners 102; 103 facing sides respective counterparts 29; 31, whereby the carriage 27; 28 between the rails 23; 24 can be moved without play parallel to a direction C and preferably in particular parallel to each other, wherein the direction C perpendicular to at least one axis of rotation 13; 14 one

Cylinder 01; 02; 03 is located and has at least one component of a drive 124 on at least one carriage 27; 28 to assign. With simultaneous movement of the carriage 27; Thus, they are preferably moved in the same direction.

Each of the carriages 27; 28 further preferably has a bearing receptacle 32, in which at least one cylinder pin 17 of the corresponding cylinder 01; 02; 03 can be rotatably mounted (Fig. 10). Furthermore, the bearing receivers 32 are each mounted on adjusting units, which has a movable in a recess 104; 106 of the respective carriage 27; 28 arranged adjusting slide 107; 108. The movement of the adjustment slide 107; 108 takes place for example by means of the carriage 27; 28 arranged adjustment drives 109; 1 1 1, which via a push rod 1 12; 1 13 each a thrust wedge 1 14; 1 16 against a on the adjusting slide 107; 108 located slope 1 17; Press 1 18, whereby the adjusting slide 107; 108 in two opposite set directions, preferably parallel to the direction C, can be shifted (Fig. 3a and 3b). As a result, a contact force of adjacent cylinders 01; 02; 03 adjusted to each other. In a preferred embodiment, the adjustment slide 107; 108 against the carriage 27; 28 and the adjusting drives 109; 1 1 1 biased, for example by means of a spring 1 19; 121st

Preferably, the adjustment slide 107; 108 and / or the adjusting drives 109; 1 1 1 with corresponding, for example in the carriage 27; 28 arranged, force sensors 122; 123 equipped, whereby a predeterminable and controlled contact force of the cylinder 01; 02; 03 adjusted to each other and can be controlled by a machine control, preferably a higher-level machine control of the entire printing press. At the same time it is thereby possible in a method described below, the carriage 27; 28 with their cylinders 01 thereon; 02; 03 a contact point of the cylinder 01; 02; 03 uniquely determine and thereby a control of the drive 124 or described in more detail below

To adjust adjusting motor 124 via the machine control, not shown.

Furthermore, a plurality of fixing elements 126, for example clamping elements 126, in particular clamping jaws 126 are arranged, for example, along the rail 24 and the running bar 103, which can each be actuated independently via a separate drive 127 or a separate drive element 127 and

Clamping a carriage 27; 28 on a respective clamping surface 128; 129 of the respective carriage 27; 28 act. In particular, fixation with respect to a movement is parallel to the rail 23; 24 to understand. The fixing elements 126 provide a frictional and / or positive connection, wherein in the following example, clamping elements 126 are described, which provide a frictional connection. However, other fixing elements 126 can also be used. An advantage of the clamping elements 126 is that a continuous selection of relative positioning of the carriage 27; 28 to the rails 23; 24 is possible. Movements for setting, for example, a diagonal register are not affected. The clamping elements 126 can be activated and deactivated and at least partially independently of one another via the or a higher-level machine control designed to be controlled. The clamping elements 126, which are described below without limiting the invention thereto as jaws 126, and / or the clamping surfaces 128; 129 may have roughened and / or surface-structured contact surfaces, it being preferred to match surface structures of co-operating surfaces to achieve optimum clamping properties. By the clamping elements 126 it is ensured that the at least two slides 27; 28 along the at least one rail 23; 24 are displaceable and can be fixed to freely selectable pre-definable positions along the rail arrangement. Preferably below the carriage 27; 28, the drive 124 is arranged, which acts for example via a push rod 131 on the nearest carriage 28, which can be moved with dissolved jaws 126 in this embodiment, the carriage 28 along with the transfer cylinder 03 arranged thereon along the rail assembly in the direction C. , Thus, two cylinders 01; 03 are moved simultaneously by means of a single drive 124. Starting from a state during the printing operation in this case the forme cylinder 01 is in mechanical contact with the transfer cylinder 03, so that at the same time the forme cylinder 01 is displaced with a displacement of the transfer cylinder 03. By way of example, the cylinders 01 are located here; 02; 03 on top of each other, whereby the cylinder 01; 03 remain in contact with each other due to their own weight (FIG. 2). But it is also possible, the cylinder 01; 03 and / or their respective carriages 27; 28 to bias against each other, for example by means of at least one, not shown in the figures, spring, which may be formed as a tension or compression spring. As a result, the possibility is created, for example, the drive 124 above the cylinder 01; 03 to order or the cylinder 01; 02; 03 horizontally or at any angle to a vertical order.

The same applies analogously for a contact or a bias voltage with the Impression cylinder 02. The clamping elements 126 are thus in particular in addition to the carriage 27; 28 and the rails 23; 24 and the drives 124 arranged.

FIGS. 3 a and 3 b schematically show perspective views of different embodiments of the positioning device 101. For the sake of clarity, not all elements shown in FIG. 2 are shown here.

In one embodiment, the rail 23, for example, at least two different, mutually parallel rails 102; 133, which in corresponding counterparts 29; 31 of the carriage 27; 28 intervene. The opposite rail 24, however, has only a running bar 103, which in corresponding counterparts of the carriage 27; 28 engages and thereby a displacement of the carriage 27; 28 in direction C allows. On the rail 24 in this case a support bar 134 is attached to a soft row of jaws 126 is fixed with their respective drive elements 127 so that the jaws 126 by means of the drive elements 127 parallel to a direction D, ie perpendicular to the rails 23; 24 and from the rail 24 to the other rail 23 pointing, and thus can be moved perpendicular to the direction C (Fig. 3a).

Here, the jaws 126 in the direction D against the clamping surfaces 128; 129 on the carriage 27; 28 are pressed, whereby the carriage 27; 28 also against the runners 102; 133 is pressed and whereby the carriage 27; 28 can be fixed in this position in the rail assembly. The case here on the rail 23 existing second runner 133 is suitably arranged so that they

Clamping surfaces 128; 129 is exactly opposite, so that when clamping the carriage 27; 28 by means of the jaws 126 substantially the running bar 133 acts as an abutment and thereby tilting the carriage 27; 28 in the

Rail arrangement is effectively avoided. If, on the other hand, the clamping jaws 126 are moved counter to the direction D, then the mechanical connection between the clamping jaws 126 and the clamping surfaces 128; 129 solved, whereby the carriage 27; 28 easily in the rail assembly in

Directions parallel to C can be moved. The jaws 126 perform only a stroke of a few tenths of a millimeter, so that even with a release of the fixation of the carriage 27; 28, the carriages 27; 28 free of play along the

Rail arrangement can be moved. It may also be provided that the jaws 126 and / or the clamping surfaces 128; 129 are roughened or have an interlocking surface structure, thereby slipping the carriage 27; 28 can be more effectively prevented in its fixed position.

In a further embodiment, the rail 23 only a running bar 102, which is a running bar 132 of the rail 24 opposite. The running bar 132 is in this case formed by the clamping jaws 126, which are arranged parallel to one another and in a row and are arranged along the direction C as seamlessly as possible next to each other. Furthermore, the jaws 126 are formed according to a running bar, so that they easily into the corresponding on the carriage 27; 28 existing

Counterparts 29; 31 engage, creating a backlash and smooth movement of the carriage 27; 28 parallel to the direction C is made possible. The jaws 126 and their respective drives 127 are further mounted on a support bar 134 so that the jaws 126 can be moved in directions parallel to the direction D by means of the drives 127 (Figure 3b).

Depending on the control of the drive elements 127 of the jaws 126, it is possible to move the jaws 126 in the direction D and a carriage 27; 28 to fix at a certain position along the rail assembly. The existing in the rail 23 running bar 102 is suitably arranged so that it is exactly opposite the runner 132 formed by the jaws 126, so that when a clamping of the carriage 27; 28 by means of the jaws 126, the running bar 102nd acts as an abutment and thereby tilting the carriage 27; 28 in the

Rail arrangement is effectively avoided.

On the other hand, if the clamping jaws 126 are moved counter to the direction D via the drive elements 127, a fixing of at least one corresponding slide 27 is effected; 28 lifted and the carriage 27; 28 is freely movable along the rail arrangement in directions parallel to the direction C. It may be expedient to limit a stroke of the clamping jaws 126 via stops (not shown) in the carrier strip 134. The jaws 126 perform only a stroke of a few tenths of a millimeter, so that even with a release of the fixation of the carriage 27; 28, the carriages 27; 28 free of play along the rail assembly can be moved. It may also be appropriate, the jaws 126 each mechanically against the in the carriage 27; 28 existing counterparts 29; 31 vorzuspannen, for example by means of spring elements, whereby in the dissolved position of the jaws 126 on the one hand, the carriage 27; 28 are kept free of play in the rail assembly and on the other the carriage 27; 28 by means of the drive 124 easily along the

Rail arrangement can be moved.

A sequence of a cylinder change with the aid of a positioning device 101 then takes place in several steps, for example as described below and also schematically illustrated in FIGS. 4 to 9. It should be noted in particular that the two adjustable cylinder 01; 03 can be fixed independently of one another in freely selectable positions along the rail arrangement, wherein they still have a common drive 124 in shared rails 23; 24 are arranged movable. This is made possible, for example, by the fact that the

Carriage assembly is arranged substantially vertically, whereby the drive 124 directly to a cylinder 03; and indirectly on a cylinder 01 in contact with this cylinder 01 is arranged acting. In this case, the drive 124 below the located in a vertical rail arrangement carriage 27; 28 be arranged and the unfixed carriage 27; 28 are supported on each other and on the drive 124 due to gravity or it may be that the unfixed carriage 27; 28 against each other and / or against the drive 124 due to a mechanical bias, for example by means of respective springs, which may be compression or extension springs support. In another embodiment, the forme cylinder 01 is arranged below the transfer cylinder 03 and the remaining printing unit is adapted accordingly.

In a first step, the carriage 27; 28 located in their first working position cylinder 01; 03 solved by the jaws 126 over their

Control elements 127 are moved counter to the direction D. It is included

expedient to move all along the rail assembly attached jaws 126 against the direction D, whereby the total possible travel for the carriage 27; 28 is released along the rail assembly (FIG. 4).

In a next step, the carriages 27; 28 with the cylinders 01 thereon; 03 by means of the drive 124 via the push rod 131 in the direction C in a first position, in which, for example, the cylinder 01 occupies a required service position for a subsequent treatment. In this position, the carriage 27 is now by means of the jaws 126 in the rail assembly

clamped by the jaws 126 are moved in the direction D (Fig. 5).

The remaining freely movable carriage 28 is subsequently moved in a further step counter to the direction C to a second position, in which the cylinder 03; occupies a service position required for a subsequent treatment. In this position, the carriage 28 is now by means of the jaws 126 in the

Rail assembly clamped by the jaws 126 are moved in the direction D (Fig. 6). This makes it possible, the cylinder 01; 03 in respective specific positions, such as service items, to proceed and fix there, the cylinder 01; 03 have no mechanical contact with each other, but rather can be spaced apart from each other (Fig. 6), so that, for example, the cylinder 01; 03 in a simple manner against other cylinders 01; 03 can be replaced, for example, against those with a different circumference (Fig. 7). In particular, this makes it possible to replace cylinders 01; 03 with appropriate storage up out of this storage. Such a suitable storage can

For example, have mentioned bearing receivers 32.

After a successful replacement of the cylinder 01; 03 is now released in a subsequent step, the clamping of the carriage 28 so that it can be moved easily in a third position in the direction C, in which the cylinder 01; 03

have mechanical contact with each other and rest on each other, so that the

Clamping of the carriage 27 can be solved easily by the jaws 126 are moved by means of their control elements 127 against the direction D (Fig. 8).

In a final step then the carriage 27; 28 with the cylinders 01 thereon; 03 in their respective associated working position opposite to the direction C and fixed there by means of the jaws 126 there (Fig. 9). By means of the on the respective carriage 27; 28 located adjusting it is then possible in subsequent steps, a desired for a particular printing process and / or required contact pressure of the cylinder 01; 03 on each other and on the

Adjust counter-pressure cylinder 02 and by means of the force sensors 122; 132 on the unillustrated higher-level machine control to control by the

Adjusting slide 107; 108 by means of adjusting drives 109; 1 1 1 in each case in or against the direction C to be moved.

The drive 124 for position determination preferably has an encoder and / or it along the rail assembly sensors are mounted at least for the determination of selected positions to an exact positioning of the cylinder 01; 02; 03 to each other to ensure. The drive 124 and / or the clamping jaws 126 can be designed, for example, electrically, pneumatically or hydraulically, so that optionally, for example, supply devices for hydraulic fluid or the like can be shared. The drive 124 may also be a via a

mechanical coupling to a drive present in the printing machine

be executed drive 124.

For safety reasons, the clamping jaws 126 preferably clamp the carriages 27; 28 in a non-controlled state in the rail assembly and release it only in a controlled state. More preferably, the bearing receivers 32 are designed as a quick-lock bearing 32.

In a preferred embodiment, the counterparts 29; 31 in the carriage 27; 28 and / or the runners 102; 103; 133 respective rollers or running balls, whereby the carriage 27; 28 easily and reliably on the runners 102; 103; 133 can be moved along the rail assembly. It is of course also possible to use other linear guides known to the person skilled in the art, instead of the dovetail guide which is mentioned by way of example.

The drive 124 can with the nearest carriage 27; 28, for example, via a clutch or rigidly connected, but it can also only via a mechanical bias by means of a spring or the weight of this slide 27; 28 coupled.

It is also possible by means of one drive 126 more than two cylinders 01; 03 to move and / or position. For example, three cylinders 01; 02; 03 are moved, then one of the cylinder 01; 02; 03 are fixed, then two cylinders 01; 02; 03 are moved, then another cylinder 01; 02; 03 are fixed and then the last of the cylinder 01; 02; 03 are moved and finally fixed as well.

In one embodiment, the bearing receptacle 32 designed as a quick-lock bearing 32 has at least one lower folding bearing shell 202, in particular

Folding bearing half 202 and an upper folding bearing shell 203, in particular

Folding bearing half 203 on. The lower folding bearing half 202 is connected via non-illustrated connecting elements fixed to a component of the printing press, for example, on a frame, a side wall or a displacement device, with which a cylinder 01; 02; 03 against other cylinder 01; 02; 03 can be adjusted in the printing press, arranged and preferably fixed.

The one, upper folding bearing half 203 is connected to the other, lower folding bearing half 202 via a hinge 204 so that the folding bearing half 203 can be pivoted about an axis of rotation defined by the joint 204, the axis of rotation preferably parallel to the axis of rotation 13; 14 at least one cylinder 01; 02; 03 is located. The pivoting of the folding bearing half 203 takes place by means of a drive 206, which via connections 207; 208 with the folding bearing half 203 and with the folding bearing half 202 and / or one, relative to the folding bearing half 202 rigid

arranged carrier plate 209 is connected. The connections 207; 208 may be used as articulated supports 207; 208 may be formed and each having a pivot axis. Preferably, these pivot axes are parallel to each other and further preferably parallel to the axis of rotation 13; 14 at least one cylinder 01; 02; 03. The drive 206 may, depending on the requirements, for example, a solenoid 206, an electric motor 206, a pneumatic cylinder 206 and / or a hydraulic cylinder 206 have, which is controlled via the higher-level machine control, not shown. On the folding bearing half 203, a retaining clip 21 1 is furthermore fastened such that it can be pivoted about a rotation axis 212 defined by a pivot joint 212 at least within a certain angular range. This axis of rotation 212 is preferably parallel to the axis of rotation 13; 14 at least one cylinder 01; 02; 03. The pivoting range can be limited, for example, by a stop 213 and a biased spring 214, whereby the headband 21 1 is pressed in the unloaded state against the stop 213 and thereby a certain first position, for example, a rest position occupies. The spring 214 pushes the

Holding bracket 21 1 so at least temporarily and always preferred in an unlocking position. Whether only the corresponding force acts or actually takes place a movement in the unlocking position, depends on an interaction with the adjusting lever 226.

The retaining bracket 21 1, in one embodiment, further at one, its axis of rotation 212 facing away, two different arms 216 and 217, which together form a molding 218. The arm 217 further has, on its outer side facing away from the formation 218, a draft 219 and a claw 221 which, in the closed state of the bearing receiver 32 described below, engage corresponding retaining bolts 222; 223 act. It can further be provided that the arm 217 has on its side facing the formation 218 a surface 224 or a pressure-resistant and dimensionally stable insert 224, on which acts as described below an adjusting lever 226 and whereby a deformation and / or abrasion of the Poor 217 of the retaining clip 21 1 due to the mechanical action of the control lever 226 on the arm 217 avoided or at least reduced.

The folding bearing half 202 has the adjusting lever 226, which by one through a

Swivel joint 227 defined axis of rotation 227 is pivotally mounted and / or rotatable. Preferably, this axis of rotation 227 is parallel to the axis of rotation 13; 14 at least one cylinder 01; 02; 03 and / or to the axis of rotation 212 of the retaining clip 21 1. The adjusting lever 226 In addition, on its side facing away from the folding bearing half 203, a connection 228 is connected to a drive 229, which is supported on the carrier plate 209 via a further connection 231. The drive 229 can, depending on the requirements, for example, a solenoid 229, an electric motor 229, a

Have pneumatic cylinder 229 and / or a hydraulic cylinder 229 and be formed controllable via a higher-level machine control, not shown (Fig. 1 1).

The adjusting lever 226 is further formed on its side facing the folding bearing half 203 side 233 so that it is in a closing of the bearing seat 32 in the

Forming 218 of the retaining clip 21 1 dips (Fig. 12). In addition, the

Adjusting lever 226 at least in a region 232 formed as a surface 232 that the region 232 on rotation of the control lever 226 about the rotation axis 227 smoothly over the corresponding surface 224 of the retaining clip 21 1 can slide.

The folding bearing halves 202; 203 always have one in each case

A substantially semicircular recess 234; 236 for receiving a bearing 19, for example, a cylinder pin 17 of a cylinder 01; 02; 03, wherein the respective recesses 234; 236 are arranged so that they form a substantially circular recess in a closed state of the folding bearing 32 (Fig. 12). In this closed position of the folding bearing 32, it is provided that in particular in one of the recesses 234; 236 inserted bearing 19, the folding bearing halves 202; 203 do not touch each other directly, but are separated by a gap 237 (Fig. 12). In the foregoing and below is of folding bearing halves 202; 203 the speech, but it can also be general

Folding bearing shells 202; 203 are used, thereby characterized by folding bearing halves 202; 203 distinguish that at least one folding bearing shell 202; 203 one

Recess 234; 236, which is not formed semicircular, but for example, a circular arc with less than 180 ° covering or even at one or more Kontaltstellen comes into contact with the bearing 19.

To close the folding bearing 32, the drive 206 is actuated via the higher-level machine control, not shown, whereby the connection 207 is pushed away in a direction E from the connection 208 and the folding bearing half 203 is pivoted about the axis of rotation in the bearing 204 in the direction F. Such

Pivoting of the folding bearing half 203 can due to the two independent drives 206; 229 independent of and in particular after insertion of a corresponding cylinder 01; 02; 03 or cylinder pin 19 done in the folding bearing 32, so that, for example, between a position control of the cylinder 01; 02; 03 is feasible. As a result, the area 233 enters the recess 218 of the retaining clip 21 1, wherein the retaining bracket 21 1 in this position is not in the retaining pin 222; 223 intervenes. A subsequent actuation of the drive 229 via the higher-level machine control, not shown, displaces the connection 228 in a direction G away from the connection 231, whereby the adjusting lever 226 is pivoted about its axis of rotation 227 in a direction H (FIG. 13). The direction H is set so that the surface 232 of the actuating lever 226 presses on the surface 224 of the retaining clip 21 1 and the headband 21 1 is rotated about its axis of rotation 212, whereby the headband 21 1 is pivoted in a direction J and the arm 217 between the retaining bolts 222; 223 is pressed. The direction J is set so that a pivoting of the

Holding bracket 21 1 in this direction J causes a locking of the folding bearing 32. It is provided that the retaining bolt 223 is resiliently mounted by means of a spring 238, whereby the claw 221 passes behind the retaining pin 223 and the folding bearing 32 locked in this position by the claw 221 engages in the attached to a folding bearing half 202 retaining pin 223.

The draft 219 of the retaining clip 21 1 is in this case against the fixed

Holding pin 222 is pressed and is formed so that at least in this position of the retaining clip 21 1, a tangent 239 to the retaining pin 222, by a contact point between retaining bolt 222 and retaining bracket 21 1 extends, with the gap 237 between the folding bearing halves 202 and 203 forms an acute angle, which includes the retaining bolt 222. This makes it possible, by means of the drive 229 via the adjusting lever 226, the headband 21 1 and in particular the arm 217 in a direction K against the

Holding pin 222 to press, which is pressed over the headband 21 1, the folding bearing half 203 in a direction L and thereby a bearing 19 and cylinder pin 17 in the bearing receivers 234; 236 is fixed (Fig. 14). The direction K is set so that the pivoting of the retaining clip 21 1 is continued in the direction of J by the pressure in the direction K or would. The direction L points from the one

Folding bearing half 203 to the other folding bearing half 202 to. Depending on the tolerance of the bearing used 19 or cylinder pin 17 while the gap 237 can be at least in the area 241 of the bearing holder 32 are reduced or disappear completely.

An opening of the bearing receptacle 32 is in principle reversed to the sequence described, wherein for unlocking the folding bearing 32, the drive 229 is operated counter to the direction G, whereby the adjusting lever 226 is pivoted against the direction H. As a result, the portion 233 of the actuating lever 226 is pressed against an inner wall of the recess 218 in the region of the arm 216, whereby the arm 217 of

Holding bracket 21 1 from the area of the retaining bolts 222; 223 is swung out and, for example, reaches its rest position. The thus unlocked folding bearing half 203 can then be pivoted by a corresponding control of the drive 206 against the direction F, whereby the folding bearing 32 is opened. A pivoting of the retaining clip 21 1 takes place at least partially in that the adjusting lever 226 releases the retaining clip 21 1 and the spring 214 causes a pivoting movement of the retaining clip 21 1. In a corresponding embodiment in which, for example, no arm 216, but only the arm 217 is arranged, which takes place

Pivoting movement solely due to the release and the spring force.

The bearing receptacle 32 designed as a quick-lock bearing 32 or folding bearing 32 Thus, at least one drive 206 for unfolding and / or collapsing the

Folding bearings 32 and at least one further drive 229 for locking and / or unlocking the folding bearing 32 and for applying a force to a in the

Folding bearing 32 located bearing 19.

The adjusting lever 226 can act on the retaining clip 21 1, whereby the retaining clip 21 1 can be brought from a first position (FIG. 12) into a second position (FIG. 13) and into a third position (FIG. 14). In this case, the headband 21 1 in the first position is not engaged with one of the retaining pin 222; 223 formed abutment, while the headband 21 1 is in the second position in engagement with this abutment and in the third position in engagement with the abutment and on this abutment and the folding bearing halves 202; 203 a force is applied to a located in the folding bearing 32 bearing 19, resulting in a play-free mounting of the bearing 19.

Preferably, the drives 206; 229 and / or the bearing receptacle 32

Sensor devices having a respective positions of the drives 206; 229 and / or the folding bearing halves 202; 203 and / or the retaining clip 21 1 and / or the adjusting lever 226 can detect and optionally transmit the machine control, whereby uncontrolled states of the quick-lock bearing 32, for example, by jamming of the retaining clip 21 1 in a locked operating state, avoided by the headband 21 1 can be brought by means of a control lever 226 from a certain position to another specific position and a continuous position control of the retaining clip 21 1 is ensured.

The bearing receptacle 32 thus has two hinged bearing halves 202 connected by a joint 204; 203, which, in the folded state with a bearing located in the bearing 32 bearing 19, a gap 237 to each other, whereby the possibility is created, the two folding bearing halves 202; 203 bias against each other and in particular the located in the bearing receptacle 32 Bearing 19 positively clamped in the bearing receptacle 32. Preferably, the respective recesses 234; 236 additional guide elements, such as collars or edges, whereby a bearing 19 of a cylinder 01; 02; 03 is limited in its axial movement and / or axially centered in the bearing receptacle 32.

In a preferred embodiment, the retaining bolt 223, the spring 238 and the arm 216 are dispensed with. Unlocking the quick-release bearing 32 is done by means of the drive 229 of the lever 226 is rotated in the appropriate direction, causing it releases the headband 21 1. The retaining bracket 21 1 is then pivoted exclusively by the force of the spring 214 in an unlocked position (Fig. 15). Everything already described, which is not inconsistent with this embodiment, applies accordingly to this embodiment.

Preferably, the headband 21 1 further comprises a releasable connection 243, which is further preferably designed as a screw 243. This connection 243 serves to fix the insert 224, which is preferably designed as a spring assembly 224, to the retaining bolt 222. The spring assembly 224 has several purposes. On the one hand, it serves to compensate for tolerances in a locking operation, that is, if by means of the adjusting lever 226 of the headband 21 1 is clamped. On the other hand, it serves to allow the adjusting lever 226 to engage. For this purpose, the surface 232 of the actuating lever 226 is formed flat and in the locked state is preferably flat on the spring assembly 224. To get into this position or to come out of this position, the lever 226 must be pivoted and during this pivoting deformed part of the control lever 226 the spring assembly 224 by this part of the control lever 226, the spring assembly 224 at least partially into a behind the spring package 224th lying cavity 242 of the retaining clip 21 1 presses. The spring assembly 224 is reversibly deformed so when changing between a locked and an unlocked position of the actuating lever 226, with a certain force must be expended for deformation and thus a certain amount of energy is transmitted to the spring assembly 224. This necessary force ensures that the change between the locked and the unlocked position of the control lever 226 can not take place by itself or accidentally. In particular, this ensures that the bearing receptacle 32 is optionally closed and locked, without the drive 229, which causes the locking and unlocking, while operating must. In particular, in the case that the drive 229 is formed as a hydraulic cylinder 229 or a pneumatic cylinder 229, a certain pressure must not be maintained permanently to ensure the locking, since this locking is ensured by the passive spring assembly 224.

Since the spring assembly 224 must pass through at least a third operating state for a transition from a first, open and thus unlocked operating state of the bearing receptacle 32 in a second, locked operating state of the bearing receptacle 32, in which the spring assembly 224 is deformed more than in the second, locked operating state , Acts at least in this third operating state, a greater force transmitted by the lever 226 force on the spring assembly 224 and therefore at least in the third operating state by the deformation more energy stored in the spring assembly 224, as in the second, locked operating condition.

In order to be able to easily replace the spring pact 224 if necessary, the spring assembly 224 is detachably arranged on the retaining bracket 21 1 by means of the connection 243. Characterized in that the unlocking of the retaining clip 21 1 is effected solely by the spring 214, the headband 21 1 is not in the unlocked state with the adjusting lever 226 in contact. In contrast to an eccentric system, as described for example in DE 40 41 497 A1, the surface 224, which mitbewirkt an adjusting movement of a locking member and optionally must be replaced, so easily accessible in the unlocked state and can through the detachable connection 243rd easily replaced.

A handling device 301 of a printing machine is designed to be in a first operating state at least two cylinders 01; 03 move back and forth between different positions, in particular a first position and a second position, in particular transport and / or lift and / or can move. One of the positions is preferably a service position, for example a position in which the cylinders 01; 03 are not in contact with each other but both are still on their cylinder pin 17 with the respective bearing receivers 32 in contact with which they are in contact in a printing operation. In such a position, the cylinder 01; 03 and the bearing receivers 32, for example, as described above by means of slide 27; 28 along rails 23; 24 are brought. This is the

Handling device 301 capable of the cylinder 01; 03 in at least two different directions M; N to move, both perpendicular to the axes of rotation 13; 14, the cylinder 01; 03 and which are not parallel to each other and of which preferably the one direction M has a component in the horizontal direction which is larger than a possible component in the vertical direction and of which the other direction N has a component in the vertical direction, the larger is, as a possible component in the horizontal direction. Preferably, the direction M is the horizontal direction and / or the direction N is the vertical direction. In a

Embodiment may be with the handling device 301 in a second

Operating state only one cylinder 01; 03 are moved at a time, for example, because of a changed position of at least two cylinder receivers 334; 336 of the

Handling device 301 relative to each other only one cylinder 01; 03 is accessible and another cylinder 03; 01 out of range accordingly

Cylinder receivers 336; 334 of the handling device 301 is located.

A first embodiment of a handling device 301 will be described below. The handling device 301 has a carriage 304, which can be moved along a rail 306 by means of a first drive 307, for example via a spindle 308, essentially in the horizontal direction. It is of course also possible instead of a spindle 308 having a drive 307 to use a belt drive 307, a chain drive 307 or a linear drive 307 or instead of the exemplified electric drive 307 to use a pneumatic or hydraulic drive 307 or to drive the carriage 304 mechanically via a gear or gears and / or racks. The same applies here to the further drives 307 described below; 326. On the carriage 304, a second rail 309 is further arranged with a second carriage 31 1, which can be moved for example by means of a drive 312 via a spindle 313 along the rail 309.

On the second carriage 31 1 are further pivot axes 314; 316, for example, hinges 314; 316 arranged over which support arms 317; 318 are each rotatably mounted with the carriage 31 1 are connected. The pivot axes 314; 316 can, for example, centric in the support arms 317; 318 (FIG. 16). Coaxial with the pivot axes 314; 316 are on the carrying arms 317; 318, respective gears 319; 321, which are in engagement with a common drive gear 322. The drive gear 322 is in this case, for example, via a shaft 323 rotatably mounted on a plate 324, wherein the plate 324, for example, fixed to the pivot axes 314; 316 is connected. Furthermore, the gear 322 is connected to a drive 326, whereby upon actuation of the drive 326, the support arms 317; 318 via the meshing gears 319; 321; 322 in one particular

Angular range can be pivoted parallel to each other. To limit the angular range, it may be provided, corresponding, not shown in the figures limit stops on the carriage 31 1 and / or on at least one support arm 317; 318 and / or at any other appropriate location.

Furthermore, at the respective ends of the support arms 317; 318 respective common lift arms 327; 328 attached, each via pivot axes 329; 331 and 332 respectively; 333 with the carrying arms 317; 318 are connected and thereby with the support arms 317; 318 form a parallelogram. The lift arms 327; 328 continue to point to their Ends respective cylinder receivers 334; 336, for example, substantially circular segment-shaped and / or semi-circular recesses 334; 336, in which the cylinder pin 17 to be taken cylinder 01; 03 can come to rest.

By a corresponding control of the drive 326 via a higher, not shown machine control, it is thus possible, the lifting arms 327; 328 to pivot into different positions, for example, in a first, also shown in Figure 16, position in which the upper lifting arm 327 is brought into a forward-facing position and in which, as described below, an upper cylinder 01; 03 can be handled, or can be brought to a second position, in which the lower lifting arm 328 is brought into a forward-facing position and in which a lower cylinder 01; 03 can be handled, or can be brought to a third position, in which both lifting arms 327; 328 in one

For example, middle position can be brought, in which both cylinders 01; 03 can be handled.

An exact location of the lift arms 327; 328 and thus also the cylinder receivers 334; 336 to each other, especially in the middle position, depends on the

geometric arrangement of the cylinder 03; 01 in the printing unit, this is chosen as an example below as perpendicular to each other. A process of handling the upper cylinder 01; 03 by means of the handling device 301 will be described below and is also shown schematically in Figs.17a to 17e. It corresponds to the second operating state of the handling device 301 described at the outset. For better understanding, elements shown in FIG. 16, for example drive elements, are not shown here.

Here, the handling device 301 is at the beginning of a cylinder change initially still in a rest position, which occupies the handling device 301, for example during normal printing operation and in which in particular the lifting arms 327; 328 out of an area of influence of the cylinder 01; 03 are located. The cylinders 01; 03 are already in one for one

Cylinder change required service position in which the cylinder 01; 03

are offset from each other and have a fixed distance to each other (Fig. 17a). The cylinders 01; 03 are at this time with their respective ones

Cylinder pin 17 mounted in their respective bearing receivers 32, wherein at this time, for example, already a fixation means of a respective component, not shown, for example, designed as a folding bearing 32 bearing receptacle 32 may be solved, so that the cylinder 01; 03 are removable.

In a subsequent operation, the upper lift arm 327 is driven by the drive

326 via the support arms 317; 318 moved to a front position, which

it is ensured that in the further procedure only the upper cylinder 01; 03 can be removed from its bearing receptacle 32, while the lower cylinder 03; 01 is out of reach of the handling device 301. For this purpose, the support arms 317; 318 pivoted in the direction L, wherein at the same time the lower lifting arm 328 is pivoted to a rear position and thus pivoted away from the working area (Fig. 17b).

In a subsequent step, the handling device 301 is now moved on its carriage 304 along the rail 306 by means of the drive 307 in a direction M in a first working position, in which the cylinder receptacle 334 of the lifting arm

327 below the cylinder pin 17 of the cylinder 01 to be removed; 03 is located (Fig. 17c). The direction M is substantially perpendicular to a plane that the assumed as parallel axes of rotation 13; 14, the cylinder 01; 03, and has at least one component, away from the handling device 301 and on one of the axes of rotation 13; 14 to assign. A subsequent lifting of the carriage 31 1 of the handling device 301 along the rail 309 in a direction N by means of the drive 312 causes the cylinder pin 17 of the cylinder 01; 03 in the Cylinder receivers 334 come to rest and the cylinder 01; 03 is lifted out of the bearing receptacles 32 (Fig. 17d). The direction N thus preferably points essentially vertically upwards. Here, the cylinder 01; 03 at least so far lifted out of the bearing receptacles 32 that they easily in a subsequent step by means of the drive 307 in direction M from the printing unit in a

Removal position can be moved out (Fig. 17e).

A procedure of handling a lower cylinder 03; 01 by means of

Handling device 301 show schematically and by way of example FIGS. 18a to 18f. This sequence also corresponds to the second operating state described at the outset

Handling device 301 and also in these figures, for the sake of clarity, the elements shown in Fig. 16 are not shown in part.

The handling device 301 is initially located at the beginning of a cylinder change in a rest position, which occupies the handling device 301 during normal printing operation and in which in particular the lifting arms 327; 328 out of the range of influence of the cylinder 01; 03 are located and the cylinder 01; 03 as already described in a service required for a cylinder change service position, in which the cylinder 01; 03 are offset from each other and each have a predetermined distance (Fig. 18a). The cylinders 01; 03 are at this time with their respective cylinder pin 17 in their respective

Bearing supports 32 mounted, at which time, for example, already a fixation by means of a respective component not shown, for example, designed as a folding bearing 32 bearing receptacle 32 may be solved, so that the cylinder 01; 03 are removable.

In a subsequent step, the lower lifting arm 328 by means of the drive 326 via the support arms 317; 318 moved to a front position, which

it is ensured that in the further procedure only the lower cylinder 03; 01 can be removed from its bearing receptacle 32 (Fig. 18b). For this purpose, the support arms 317; 318 pivoted against the direction L, wherein at the same time the upper lifting arm 327 is pivoted to a rear position and thus from the

Work area is pivoted away.

It may be necessary in this case, in a subsequent step, the lifting arms 327; Lower 328 along the rail 309 counter to the direction N as far as the lifting arm 328 or at least the cylinder receptacle 336 passes below the cylinder pin 17 and / or below the bearing receptacle 32, whereby the lifting arm 328 can be easily moved under the cylinder pin 17 (Fig. 18c ).

In a subsequent step, the handling device 301 is now moved on its carriage 304 along the rail 306 by means of the drive 307 in the direction M in a first working position, in which the cylinder receptacle 336 of the lifting arm 328 below the cylinder pin 17 of the cylinder 03; 01 is located (Fig. 18d). Subsequent lifting of the carriage 31 1 of the handling device 301 along the rail 309 in the direction N by means of the drive 312, causes the cylinder pin 17 of the cylinder 03; 01 come to lie in the cylinder receivers 336 and the cylinder 03; 01 is lifted out of the bearing receptacles 32 (FIG. 18e). Here, the cylinder 03; 01 at least so far lifted out of the bearing receptacles 32 that it can be easily moved out in a subsequent step by means of the drive 307 in the direction M from the printing unit in a removal position and not at the same time with the still in its bearing seat 32 cylinder 01; 03 is collided or obstructed by it (Fig. 18f).

A sequence of handling both cylinders 01; 03 by means of

Handling device 301, which corresponds to the above-mentioned first operating state of the handling device 301, show schematically and by way of example FIGS. 19a to 19d. Also in these figures, for the sake of clarity, some are in FIG. 1 not shown elements shown.

The handling device 301 is initially located at the beginning of a cylinder change in a rest position, which occupies the handling device 301 during normal printing operation and in which in particular the lifting arms 327; 328 out of the range of influence of the cylinder 01; 03 are located and the cylinder 01; 03 as already described in a service required for a cylinder change service position, in which the cylinder 01; 03 are offset from each other and their axes of rotation 13; 14 to each other at a predetermined distance (Fig. 19a). The cylinders 01; 03 are at this time with their respective cylinder pin 17 is mounted in their respective bearing receivers 32, wherein at this time, for example, a fixation by means of a respective component, not shown, for example, designed as a folding bearing 32 bearing receptacle 32 may be solved so that the cylinder 01; 03 are removable. It may be provided that the rest position of the lifting arms 327; 328 already for the removal of both cylinders 01; 03 required position corresponds, whereby an additional pivoting of the lifting arms 327; 328 by means of the support arms 317; 318 and the drive 326 is not required.

In a subsequent step, the handling device 301 is now moved on its carriage 304 along the rail 306 by means of the drive 307 in the direction M in a working position in which the cylinder receivers 334; 336 of the lift arms 327; 328 each below the respective cylinder pin 17 of the cylinder 01; 03 are located (Fig. 19b).

A subsequent lifting of the carriage 31 1 of the handling device 301 along the rail 309 in the direction N by means of the drive 312 on the one hand causes the cylinder pin 17 of the cylinder 01; 03 in the respective cylinder receivers 334; 336 come to rest and the cylinder 01; 03 are lifted out of their respective bearing receivers 32 (FIG. 19c). Here, the cylinder 01; 03 at least so far lifted out of the respective bearing receivers 32 that they can be easily moved out in a subsequent step by means of the drive 307 in direction M from the printing unit in a removal position (Fig. 19d).

This means that the handling device 301 is designed to be ingestible by means of a drive 307 at least two layers, wherein in a first position with one of the at least two cylinders 01; 03 in at least one operating state

cooperating cylinder receivers 334; 336 of the handling device 301 with respect to a horizontal direction on another side of in at least one operating state with the same of the at least two cylinders 01; 03 cooperating bearing receivers 32 are, as in a second position.

Thus, at least in this embodiment, the cylinders 01 are preferred; 03 always moves parallel to each other by means of the handling device 301.

It should be noted that the working positions of the carriages 304; 31 1 along their respective rails 306; 309 depending on the cylinder or cylinders 01 to be removed; 03 may be different and each monitored, for example, by means not shown sensors and / or control devices and / or can be controlled. Such sensors and / or controllers may be connected to a machine controller.

Another embodiment of a handling device 301 will be described below. In contrast to the previous embodiments, the lifting arms 327; 328 as short lift arms 327; 328 executed, each having a cylinder receiving 334; 336 and which via respective push rods 337; 338 on respective linear actuators 339; 341 are attached. The linear drives 339; 341 are in this case mounted on the carriage 31 1 a vertical displacement device, which has at least one rail 309, a carriage 31 1 and a drive 312, wherein the carriage 31 1 can be displaced by means of the drive 312 via a drive shaft 313, for example a spindle 313 along the rail 309 (FIG. 20).

Linear actuators 339; 341, for example, as a pneumatic cylinder 339; 341, electric linear actuators 339; 341 or hydraulic linear drives 339; Be executed 341, which can each be operated via a higher-level machine control. This makes it possible, by actuating either the linear drive 339 or 341 only one of the cylinder 01; 03 substantially in accordance with a procedure already described from its bearing receptacle 32 to remove or both cylinder 01; 03 at the same time. It is expedient at least the vertical distance of the linear drives 339; 341 to be chosen so that it is substantially the vertical distance of the cylinder 01; 03 corresponds to their service position.

With the handling device 301 so, depending on your needs, either a cylinder 01; 03 or two cylinders 01; 03, in other conceivable embodiments more than two cylinders 01; 02; 03, automatically without intervention of an operator, ie

in particular driven by a machine and / or driven from a first position, for example a suitable for a printing operation working position or a service position, in at least a second, for example, easily accessible from outside the printing press, position, for example, a replacement position or removal position or other service position. In accordance with the reverse procedure, of course, cylinder 01; 02; 03 are brought from the second position to the first position. In the second position, for example, the service position and in particular in the removal position located cylinder 01; 02; 03 can be further treated manually or preferably by means of suitable machine-controlled means. For example, the cylinders 01; 02; 03 are removed by means of an external handling device, such as a trolley, a swivel arm or a pulley, and against other cylinders 01; 02; 03 can be replaced or it can also only cleaning or a Printing form change or a blanket change can be performed.

Preferably, the lift arms 327; 328 and / or the bearing receivers 32

Means for axially positioning at least one cylinder 01; 02; 03, whereby corresponding cylinder 01; 02; 03 can be aligned when inserting into the printing unit based on attached to the respective printing unit reference marks.

The handling device 301 is particularly suitable for printing machines and / or painting machines, in which a frequent replacement of cylinders 01; 03 is provided, for example, for variable-format rotary printing machines that process, depending on the printing job to be printed, printing forms of different print lengths.

Preferably, the bearing receivers 32 of the cylinder to be exchanged 01; 02; 03 equipped with at least its own drive and, for example, designed as a folding bearing 32 and Schnellverschlusslager 32 so that they in particular on the

Machine control to open and / or unlock, so that no manual intervention of an operator is necessary to the cylinder 01; 03 after one

To bring printing operation in a corresponding service position and finally in a corresponding removal position.

In a further embodiment of the handling device 301, all lifting arms 327; 328 relative to each other rigidly arranged and can only be moved together. It follows that all cylinders 01; 03, with the

Handling device 301 can be moved, can only be moved together (Fig. 21). This embodiment is recommended if predominantly or always all cylinder 01; 03 should be replaced at the same time. The embodiment then essentially corresponds to the embodiment shown in FIG. 20, with the difference that the linear drives 339; 341 and instead of the Cylinder mounts 334; 336 are arranged immovably to each other. Their use is analogous to the case described above, which is also shown in FIGS. 19a to 19d. Also in this case, it is possible to have only one of the cylinders 01; 03 exchange, for example, although by all cylinders 01; 03 are brought by means of handling device 301 in their corresponding removal position, but there only the cylinder 01; 03 is removed, which is to be replaced, while the other cylinder 01; 03 together with the newly set cylinder 01; 03 back to his service position and / or to his working position is returned. In Fig. 21 also another embodiment of the drive 312 is shown, which in this case has at least one hydraulic cylinder or a pneumatic cylinder whose movements via a lever 342 in a vertical movement of the carriage 31 1 and thus the associated lifting arms 327; 328 is converted.

With this embodiment, costs can be saved, since fewer drives and moving parts are incurred and with appropriate interaction with others

Machine components nevertheless a full functionality remains guaranteed.

In the following, a coupling device for coupling at least one cylinder 01; 02; 03 to at least one corresponding drive 16 described. Preferably, for each cylinder 01; 02; 03 with its own drive 16 at least one of the bearing receptacles 32 a coupling device, by means of which the cylinder 01; 02; 03 coupled in a coupled operating state with its drive 16, ie non-positively, in particular frictionally engaged and optionally also positively connected, in particular with respect to rotational movements about the rotation axis 13; 14 of the cylinder 01; 02; 03. For this purpose, the corresponding bearing receptacle 32 a to the rotation axis 13; 14 of the cylinder 01; 02; 03 and to a rotation axis 13; 14 of the drive 16 concentric opening through which a coupling body 603 of the coupling device, which is preferably designed as a coupling cylinder 603, can be moved concentrically at least partially. Hereinafter, the coupling device in the embodiment with a Coupling cylinder 603 described, however, the corresponding information applies

correspondingly also for a general coupling body 603.

The rotation axis 13; 14 of the cylinder 01; 02; 03 is equal to a rotation axis 13; 14 of the coupling cylinder 603 and the rotation axis 13; 14 of the drive 16. The

Coupling cylinder 603 is concentrically guided within a component 61 1 of the drive 16, preferably within a hollow drive shaft 61 1 of the drive 16, wherein the drive shaft 61 1 may be performed simultaneously, for example, as a rotor 659 of an electric motor 16 serving as a drive 16. This component 61 1 of the drive 16 is thus rotatable and / or arranged in rotation. For moving the coupling cylinder 603 in the drive shaft 61 1 along the common axis of rotation 13; 14 is preferably arranged outside the drive 16 displacement device 612, for example, a linear motor 612, an electric motor 612, a solenoid 612, a hydraulic drive 612 or a pneumatic cylinder 612, respectively. The

Displacement device 612 is thus independent of the drive 16 operable. The coupling body 603 can thus be arranged axially so that no plane exists, which is perpendicular to the axis of rotation 13; 14 of the cylinder 01; 03 is located and the same time the cylinder 01; 03 and the coupling body 603 intersects.

For frictional, ie in particular frictional and / or positive connection of the drive 16 with the cylinder 01; 02; 03, the coupling cylinder 603 from a first position in which the coupling cylinder 603 is not in a part of the

Cylinder pin 17 protrudes and neither frictionally nor positively with neither the cylinder 01; 03 is still connected to the drive 16 and which corresponds to a decoupled operating state, in the direction of the cylinder pin 17 to moved to a second position and in this case provided in a concentric with the rotation axis 13; 14 of the cylinder 01; 02; 03 lying recess 613 of the cylinder pin 17 and the cylinder 01; 02; 03, for example, a socket 613, pushed. The recess 613 is in this case adapted to an outer shape of the coupling cylinder 603 and in a preferred embodiment, for example, also cylindrical, whereby the coupling cylinder 603 in any rotational position of the cylinder 01; 02; 03 can engage relative to the coupling cylinder 603 in the recess 613, wherein a diameter of the recess 613 is slightly larger than a diameter of the coupling cylinder 603, so that the movably mounted coupling cylinder 603 can be easily moved into the recess 613 and out of the recess 613 out , It should be noted that at least the positive engagement in each case to rotational movements about the axis of rotation 13; 14 of the cylinder 01; 02; 03 relates. Related to

Translational movements, in particular in directions with components perpendicular to the axis of rotation 13; 14 of the cylinder 01; 02; 03 are not affected.

The coupling cylinder 603 has in its interior at least one longitudinal channel 604 and at least two transverse channels 606; 607, which are connected to the longitudinal channel 604, wherein at least two ends of the respective transverse channels 606; 607 end at at least two different positions along a lateral surface of the coupling cylinder 603 and thus form corresponding openings in this lateral surface. The longitudinal channel 604 is preferably as a bore of a cylinder pin 17 of the cylinder 01; 02, 03 opposite end face of the coupling cylinder 603 executed, also crosses the second transverse channel 607 preferably designed as a bore and ends in the region of the first transverse channel 606, which is also preferably designed as a bore. In a coupled operating state, ie in a coupled-in second position of the coupling cylinder 603 , Are at least two openings so that they in a first region in the interior of the recess 613 of the cylinder 01; 02; 03 lie and are at least two openings so that they lie in at least a second region in the interior of the running as a hollow cylinder drive shaft 61 1, in each case in particular relative to an axial direction. The openings are covered by a flexible material 614 and liquid-tight and / or gas-tight with the

Coupling cylinder 603 connected. As a flexible material 614 here, for example, a thin-walled metal cylinder 614 can be used, which with the coupling cylinder 603 for example, soldered, welded or glued or a plastic material 614, which is glued to the coupling cylinder 603. It can also be provided here that at least one additional groove, which surrounds the coupling cylinder 603 and is connected to the longitudinal channel 604, is provided at least in the region of the openings, which groove is completely covered by the flexible material 614 (FIGS. 22 and 27).

A frictional and preferably also positive connection between at least the cylinder 01; 02; 03, the coupling cylinder 603 and the drive shaft 61 1 takes place in that the longitudinal and transverse channels 604; 606; 607 of the coupling cylinder 603 are filled with a hydraulic medium, for example with a gas or preferably with an incompressible hydraulic fluid and an overpressure is exerted on this medium. As a result, the flexible materials 614 in the region of the openings are preferably reversibly deformed so that an effective diameter of the coupling cylinder 603 is increased in these areas and jamming of the coupling cylinder 603 with the cylinder 01; 02; 03 and the drive shaft 61 1 and thus a frictional and / or positive connection is achieved. Upon removal of the overpressure, the flexible material 614 preferably resumes its original shape. There are also other hydraulic media conceivable, such as appropriate sand.

The occurring deformations of the flexible materials 614 are included

adapted diameters of the respective cylinder 01; 02; 03 or coupling cylinder 603 and recesses 613 in the range of a few tenths of a millimeter or less, so that as flexible materials 614 as already mentioned and thin-walled metal cylinder 614 can be used, which in a particularly advantageous manner with the

Coupling cylinder 603 can be welded. Preferably, the coupling cylinder 603 in the region of the thin-walled metal cylinder 614 has a diameter smaller by twice the wall thickness of the thin-walled metal cylinder 614, so that the

Coupling cylinder 603 after applying the thin-walled metal cylinder 614 has a same diameter over its length. Pressurizing one through the longitudinal channel 604 and the transverse channels 606; 607 formed volume 608 can for example take place in that the volume 608 is filled with the hydraulic medium, which acts on a plunger 623 in the interior of the coupling cylinder 603, which can be changed by means of a push rod 624 in position and in particular pressed into the volume 608 inside can be. For this purpose, the plunger 623, for example, movably arranged in an example cylindrical bore 609 so that it can be moved along an axis of this bore 609. The bore 609 is connected to the volume 608 and forms at least up to the plunger 623 a common

Volume 608, which is filled with the hydraulic medium. To pressurize the common volume 608 with an overpressure, the plunger 623 can be subjected to mechanical or pneumatic or hydraulic force. The plunger 623 may be designed so that it has additional, not shown in the figures, sealing elements, whereby leakage of the incompressible liquid is prevented. More preferably, the plunger 623 acts on the inside of the incompressible liquid filled volume on a compression spring 626, which is pressed at a removal of the pressurization of the plunger 623 in an opposite direction, resulting in a low negative pressure inside the filled with incompressible liquid volume and flexible materials 614 are brought into their original form. Furthermore, between the plunger 623 and the push rod 624, a further compression spring 627 may be arranged, whereby temperature-induced volume changes of the hydraulic fluid and consequent pressure changes inside the filled with incompressible fluid volume can be effectively compensated (Fig. 26).

The push rod 624 may, for example, in a direction along the

Rotation axes 13; 14, the cylinder 01; 03 are arranged throughout hollow push rod 628 and preferably completely through this push rod 628th extend, wherein the push rod 628 is fixedly connected to the coupling cylinder 603. This makes it possible, the coupling cylinder 603 inside the drive shaft 61 1 along the axis of rotation 13; 14 of the cylinder 01; 02; 03 by means of the push rod 628 to move and thereby the coupling cylinder 603 from the recess 613 of the

Cylinder pin 17 fully extend. As a result, the cylinder 01; 02; 03 completely decoupled from the drive 16 and can be removed from its bearing receivers 32, for example by a movement perpendicular to its previous axis of rotation 13; 14. Preferably, a stroke of the coupling cylinder 603 in the drive shaft 61 1 is limited by at least one corresponding stop 629.

For driving the cylinder 01; 02; 03 is still on the carriage 27; 28 a drive 16 arranged so that this at least with its motor housing 619 on the carriage 27; 28 is supported, that is stationary relative to the carriage 27; 28 is arranged. In this case, the drive 16 is, for example, an electric motor 16 whose stator 658 is fastened in the motor housing 619 or housing 619 and whose rotor 659 comprises at least one drive shaft 61 1 with rotor windings 661 fastened thereto. In this case, the drive shaft 61 1 is mounted, for example, in each case at the ends of the motor housing 619 in bearings 649, preferably roller bearings 649, for example roller bearings 649. Furthermore, the drive shaft 61 1 is designed to receive the coupling cylinder 603 hollow. An inner diameter of the drive shaft 61 1 is also selected to be slightly larger than the diameter of the coupling cylinder 603, whereby the coupling cylinder 603 easily in the interior of the drive shaft 61 1 via the push rod 628 along the common axis of rotation 13; 14 can be moved. The movement of the

Coupling cylinder 603 via the push rod 628 along the common

Rotation axis 13; 14 in a direction A by means of the outer drive 612. The direction A is parallel to the axis of rotation 13; 14 of the cylinder 01; 02; 03 and points from the cylinder 01; 02; 03 off and on the drive in 16 too.

The drive 612 in this case is supported, for example, by a holder 632 on a the motor housing 619 of the drive 16 connected bracket 621 from. The drive 612 further has at least one guide rod 633 or guide shaft 633, on which at least one sliding element 634 is arranged, which can be moved by means of at least one push rod 636 through the drive 612 along the guide rod 633. Furthermore, at least one driver 637 is attached to the at least one sliding element 634, which has at least one claw 638 on a side facing away from the at least one sliding element 634. The at least one claw 638 engages in a recess formed on the push rod 628 of at least two spacers 639 and 641 in such a way that, when the push rod 636 moves in the direction A, the coupling cylinder 603 is likewise moved in the direction A. In this case, the coupling cylinder 603 moves via the push rod 636 and the at least one attached sliding member 634, the at least one located on the driver 637 claw 638 against the spacer 641, whereby the coupling cylinder 603 is moved via the push rod 628 in the direction A. As a result, the coupling cylinder 603 from the recess 613 of

Cylinder pin 17 moved out and the cylinder 01; 02; 03 separated from the drive 16 (Fig. 23).

Conversely, for engaging the drive 16 to the cylinder 01; 02; 03 moves the push rod 636 by means of the drive 612 counter to the direction A, whereby the claw 638 via the spacer 639, the push rod 628 and thus the

Coupling cylinder 603 moves into the recess 613 of the cylinder pin 17 in. The push rod 628 can additionally be supported via at least one slide bearing 642 in the interior of the drive shaft 61 1. The locking of the coupling cylinder 603 takes place in this case so that after incursion of the coupling cylinder 603 into the recess 613 of the cylinder pin 17 which is filled with incompressible liquid volume 608 is subjected to an overpressure, whereby at least the flexible material 614 in the region of the first transverse channels 606 expands and frictionally and / or

positively conforms to the inner wall of the recess 613. At the same time, the flexible material 614 expands in the region of the second transverse channels 607 and clings to the inner wall of the drive shaft 61 1 frictionally and / or positively, whereby the cylinder 01; 02; 03 frictionally engaged and / or positively connected to the drive 16.

For locking the coupling cylinder 603 in the recess 613 and in the

Drive shaft 61 1 protrudes the push rod 624, for example via a cylinder 01; 02, 03 facing the end of the push rod 628 and has at its end a thread which engages in a fixed to the push rod 628 counterpart, whereby upon rotation of the push rod 624, this push rod 624 along the axis of rotation 13; 14 is moved relative to the push rod 628 and thereby exerts a pressure on at least the plunger 623. The rotation of the push rod 624 may, for example, be such that a corresponding, for example electrically operated, screwing tool 643 with a corresponding tool head 644 into a corresponding recess 646 on a cylinder 01; 03 remote from the end of the push rod 624 engages, which depending on the direction of rotation of the screwing tool 643, the push rod 624 relative to the push rod 628 can be screwed in or out, so in the axial direction with respect to the rotation axis 13; 14 of the cylinder can be moved. Since in printing operation, the cylinder 01; 02; 03, the coupling cylinder 603, the drive shaft 61 1, the push rod 628 and the push rod 624 form a firmly connected unit and thus perform a common rotation, preferably the tool head 644 is moved out at least during the printing operation of the recess 646 and thus mechanically from the Recess 646 separated. For this purpose, the screwing tool 643 is fixed, for example, on a mounting plate 647, which can be moved via a lifting device 648 parallel to the direction A. It can also be provided that the spacer 641 simultaneously represents a screw head of the push rod 624.

Furthermore, a page register adjustment device 602 is arranged. To adjust the side register at least the forme cylinder 01 and the drive shaft 61 1 in bearings 19; 649 stored, which have a certain axial play. This creates the possibility of the coupling cylinder 603 and in the coupled operating state, the cylinder 01 and connected to the cylinder 01 via the coupling cylinder 603

Drive shaft 61 1 in and against the direction A parallel to the axis of rotation 13 of the forme cylinder 01 to move, in particular relative to a side frame wall 402. Such bearings 19; 649, for example, roller bearings 19, 649 such as roller bearings 19; Be 649. A displacement is preferably in the range of a few tenths of a millimeter to a few millimeters. For this purpose, an end facing away from the cylinder 01 of the drive shaft 61 1, for example, with at least one

largely or completely play-free and axially non-displaceable bearing 616, for example, a ball bearing 616, provided, the outer ring is enclosed in a sleeve 617 and secured by a washer 651 on the sleeve 617. The sleeve 617 in turn is via a thread 618, in particular external thread 618 with a, for example, attached to a motor housing 619, a corresponding

Internally threaded, counterpart 621 and a holder 621 rotatably connected, so that upon rotation of the sleeve 617 relative to the counterpart 621 the

Drive shaft 61 1 and connected to the drive shaft 61 1 via the coupling cylinder 603 cylinder 01 parallel to the rotation axis 13; 14 is moved. For this purpose, for example, the sleeve 617 can be rotated via an arranged drive 622 as required, preferably in that the disk 651 is designed as a toothed wheel, at least in a certain angular range, on which the drive 622 engages, for example via a pinion 652. The drive 622 can simultaneously be designed so that it acts as a brake when not operating the drive 622 and a

unwanted or unintentional twisting of the sleeve 617, whereby a

Adjustment of the page register would be effectively prevented. The drive 622 or actuator 622 may be designed for this purpose, for example, as a self-locking worm drive 622 or gear drive 622 or have at least one additional, not shown in the figures, brake device or fixing device. The drive 622 can, for example, electric, pneumatic, hydraulic or be mechanically formed.

FIGS. 24 and 25 show a respective left and right, respectively

Side register position of the forme cylinder 01. If, as shown in FIG. 24, the drive 622 is rotated in a direction B, ie with an axis of rotation pointing in the direction A, the sleeve 617 is unscrewed from the thread 618 via the disk 651 and the forme cylinder 01 accordingly shifted in the direction A. If the drive direction of the drive 622 is reversed and now points counter to the direction B, as shown in FIG. 25, the sleeve 617 is inserted into the thread 618 via the washer 651

screwed in, causing the forme cylinder 01 is moved counter to the direction A accordingly. An adjustment of the side register can be done both during and outside of the normal printing operation and independent of this, wherein the forme cylinder 01 is moved only in directions parallel to its axis of rotation 13. It is possible to use electric, pneumatic, hydraulic or mechanically coupled drives. By means of other components of the printing press, however, influence on the circumferential and / or

Diagonal registers are taken.

The fact that the coupling cylinder 603 in each possible angular position to the cylinder 01; 02; 03 is connectable, it is necessary, at least in the case of the forme cylinder 01 to determine a reference position of the cylinder 01 at least with respect to the circumferential register, d. H. with respect to a position of the printing material 04 and / or with respect to a position possible other form cylinder 01. A similar arrangement can of course for other cylinder 02; 03 are used, for example, a position of a

Cylinder channels of a transfer cylinder 02 to control and / or targeted to influence. For this purpose, the drive shaft 61 1 preferably has a rotational angle sensor 653 fixedly connected thereto, for example preferably rotary encoder 653, more preferably absolute value encoder 653, with which the rotational position of the drive 16 and in particular the rotational position of the drive shaft 61 1 preferably by means of a not can be determined absolute superior machine control by the rotation angle sensor 653 is rotatably arranged to a bearing seat 32 of the corresponding cylinder 01.

To support the rotation angle sensor 653, this preferably has at least one arm 654 which is arranged on the guide rod 633 so that the arm 654 is mounted without play in the direction of rotation and movably along the guide rod 633, thereby ensuring that the rotation angle sensor 653 is independent of an axial position of the drive shaft 61 1 always a same support angle, d. H. has a same reference position. It is further provided that the forme cylinder 01 has at least one reference mark 656 which can be scanned via at least one preferably mounted on the bearing holder 32 sensor device 657 and can be forwarded to a higher-level machine control, not shown, from which in conjunction with position data of the rotation angle sensor 653 a unique Reference angular position of the forme cylinder 01 can be determined and / or the

Form cylinder 01 can be brought by means of the drive 16 in this reference angular position.
