Description

The The invention relates to a trolley for interchangeable Cylinder according to the preamble of the claim 1, and a method for conveying at least one cylinder according to the preamble of claim 13.

Rotary presses work on a rotary printing principle, such as a Flexographic printing, offset printing, high pressure, gravure printing, etc., in which a print template of the printed image to be printed in a lateral surface one or more form cylinder is introduced or as a printing plate is clamped on the lateral surface of a forme cylinder, and during the printing process via an unwinding of the forme cylinder over its lateral surface the Print image either directly or via downstream transfer cylinders is transferred to a substrate. At the same time essentially independent of the production speed and from other external influences maintaining high print quality is above it In addition often provided, the pressure rollers by means of a Tempering device at a certain adjustable temperature to operate, for example, by the pressure rollers of a cooling fluid be flowed through.

About that In addition, it is particularly in the printing of web-like Printing material required, one printing length of one printed image for different print jobs at least in Steps to make variable, which, for example, in packaging printing the possibility is created of different sizes To design packaging. Especially in the mentioned packaging printing a variety of different types of packaging such as tubular bag packaging or folding boxes of different shapes and sizes used, it is necessary such rotary presses manufacturer so that different form cylinder and / or transfer cylinders and / or plate rollers with different Scope can be used in the printing press.

The change the different perimeters of the cylinder can, for example, here by replacing, on a cylinder core with a specific one Diameter slidable, sleeves or so-called sleeves with different outside diameters or by exchange complete cylinder are made. This is done, for example manually by an operator, in which case the cylinders from each other must be turned off and for the exchange against Cylinder with a different diameter the distance of the Cylinder to each other must be such that also cylinder with a maximum diameter easily replace. Replaceable sleeves are known, but usually carry the Disadvantage that a tempering of the lateral surface of the sleeves not possible for all sleeves alike is, since usually only the cylinder on the the appropriate Sleeve is wound up, has means for tempering and then the corresponding surface temperatures of the Cylinders are transmitted through the sleeve, ultimately a surface temperature of the lateral surface of the Adjust sleeves. Different sized sleeves show There are several characteristic properties, such as thermal conductivity or heat capacity.

For this For example, the cylinders can be stored in eccentric bushes be, which are pivoted by means of a suitable drive can. It is only a limited pivoting adjacent Cylinders to each other on a circular arc possible, which is when replacing cylinders of a first diameter against cylinders of a second diameter a complex Readjustment of the cylinder requires each other.

It is also known the position of the cylinder to each other by means of a set each linear actuator, causing the cylinder and in particular associated bearing receptacles of the cylinder in each case to each other can be moved. Everybody has to go along one certain direction to be moved cylinder a respective linear actuator be assigned, resulting in a complex structure with appropriate Costs result.

An exact match of a print image on front and back of a double-sided substrate is called register ( DIN 16500-2 ), In multicolor printing one speaks of the passer ( DIN 16500-2 ), when the individual print images of the different colors are combined exactly matching a picture. Various correction requirements and correction methods are known in connection with the register or register when printing in multicolor rotary printing presses. 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 material to be printed, can be achieved for example by moving a forme cylinder 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 to correct the diagonal register or the diagonal register, ie an inclination of the printed image, for example when printing plates on a plate cylinder are not aligned in the appropriate angle, thereby creating a skew of the printed image of the corresponding color on the substrate. For this purpose, for example, in rotary printing machines, usually the form cylinder is tilted so that its axis of rotation is no longer parallel to the axis of rotation of the transfer cylinder. In the following, for the sake of simplicity, only side-perimeter or diagonal registers will be discussed, but it is always equally meant for the side-perimeter or diagonal register.

By the DE 44 20 771 A1 a rotary printing machine with means for automatically replacing the printing cylinder is known, wherein a corresponding cylinder is driven by means of a carriage from outside the printing press in the printing press and is solved within the machine via suitable means of the car and fixed rotatably in the printing press.

By the DE 692 16 900 T2 a rotary printing machine is known which comprises a releasable cylinder which is held in the printing operation in the machine frame and removed by means arranged on a carriage lifting means from this position and placed in a receptacle on the carriage and is subsequently transported by means of the carriage from the printing press. The car has two shots, for example, serve to simultaneously record a developed and a cylinder to be installed.

Of the Invention is the object of a trolley for interchangeable cylinders and a method of transport to create at least one cylinder.

The The object is achieved by the features of claim 1 and solved by the features of claim 13.

The particular advantages of the invention are that by being able to print two together simultaneously remove cylinders in contact from a printing unit a cylinder change can take place particularly fast and time-saving, For example, a change of a forme cylinder against a forme cylinder with varying degrees and a simultaneous change of one with the form cylinder cooperating transfer cylinder.

One Another advantage is that cylinder both in the printing press as well as in a trolley are mounted only on their pins and thereby a cylinder surface, in the printing operation for a color transfer is responsible, from damage is protected.

One Another advantage is that cylinder directly from the printing press be transferred to cylinder receivers of the trolley can and therefore cumbersome and / or potentially dangerous Transport operations, such as a manual lifting the cylinder from the printing press in the dolly, not necessary. This saves time and reduces hazards from operators.

One Another advantage is that cylinder directly from the trolley can be handed over to a storage magazine and thereby cumbersome and / or potentially dangerous Transport operations, such as a manual lifting the cylinder from the trolley into the supply magazine, not necessary. This also saves time and reduces hazards from operators.

One Another advantage is that it, by a sufficient large number of storage locations in the storage magazine, is possible, removed from the printing press cylinder in to introduce the storage magazine and in a subsequent step issue cylinders to be re-installed from the storage magazine so that a cylinder change take place as quickly as possible can.

One Another advantage is that by means of automatically movable lifting arms of the trolley a transfer of cylinders between printing press and transport cart and between transport cart and supply magazine is possible without an operator would have to intervene. By the arrangement of the lifting arms are in particular less lifting arms necessary than when this at the printing press and would be arranged on the storage magazine.

One Another advantage is that by cylinder shots ensures the lifting arms safe transport of the cylinder is.

One Another advantage is that by a fixation of the trolley relative to the printing press or relative to the supply magazine a transfer of cylinders between the trolley and the printing press or the storage magazine particularly safe and less prone to interference can be.

One Another advantage is that by appropriate actuators on the lifting arms of the dolly also with non-automatically opening Lageraufnahmen can interact and thereby a cylinder transfer is made possible without intervention of an operator.

Another advantage is that through a connectable to the machine control control of the trolley on the one hand the trolley, in particular during transport of cylinders must not be continuously connected to the machine control and on the other hand, a transfer of cylinders, for example, between printing press and trolley better synchronized and executed.

One Another advantage is that by own transport wheels and its own drive the trolley flexibly used No major changes and alterations of driveways of the trolley Reconstruction costs require, unlike, for example would be the case with recessed in the ground chain drives.

One Another advantage is that by a rail for guidance of the trolley a purposeful movement of the trolley is possible. Such a rail can be used to uphold the above said advantage be easily removable and mainly relocated serve an orientation of the trolley.

One Another advantage is that the trolley in interaction with the printing press and the storage magazine a fast, safe and automatically, d. H. without manual intervention of an operator, performed change of one or more cylinders one Printing machine allows.

One Another advantage is that sufficient by the arrangement many storage spaces in the supply magazine and the possibility of handovers of cylinders between the dolly different storage locations to carry out a quick replacement of cylinders is possible because the dolly only once between the printing press and the supply magazine must reciprocate and the supply magazine at the same, as close as possible to the Printing press arranged location can remain. transport times are thereby minimized.

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 as a form cylinder 01 trained cylinder 01 that works as a plate cylinder 01 may be formed and at least one as a printing cylinder 02 trained cylinder 02 or impression cylinder 02 and optionally at least one as a transfer cylinder 03 trained cylinder 03 , the one blanket cylinder 03 can be on. If the printing unit is designed as a rotary offset printing unit, form cylinder work 01 , Transfer cylinder 03 and impression cylinder 02 together in the printing operation in a known manner. The form cylinder 01 is inked by an inking unit with printing ink according to a printed image to be printed. The selective on the form cylinder 01 arranged ink is made by rolling contact on the transfer cylinder 03 transferred from there and also by means of rolling contact on a substrate 04 transferred between the transfer cylinder 03 and the impression cylinder pressed against it 02 is passed. The substrate 04 For example, it can be sheet or arcuate and it can be all sorts of substrates 04 such as paper, cardboard, cardboard, textiles, plastic or metal are printed.

The Invention can also be applied to other printing methods such as High-pressure, flexo or gravure transfer. Furthermore is when the talk is about transferring that ink is included, as well as a transfer of paints and the invention therefore also applies to painting equipment.

In one embodiment of such a printing machine are a counter-pressure cylinder 02 , a transfer cylinder 03 and a form cylinder 01 arranged. The form cylinder 01 is at least one, but preferably two inking rollers 06 in rolling contact. The at least one inking roller 06 stands with a paint roller 07 in rolling contact, this ink roller 07 preferably as an anilox roller 07 is trained. The ink roller 07 stands with a color source 08 in contact with the color source 08 in the event that the paint roller 07 as an anilox roller 07 is formed, preferably as a chambered doctor blade 08 is trained. There are also other embodiments conceivable in which, for example, the color source 08 as a color box 08 is formed and the ink roller 07 as at least partially in the ink of the ink fountain 08 submerged ink ductor 07 is trained. 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 more rolls 11 ; 12 are arranged, not on a direct Farbtransportweg between ink roller 07 and form cylinder 01 lie, but for example as Farbreibwalzen 12 are formed and serve a homogenization of a color film, based on components of the printing unit and in particular on the forme cylinder 01 located ( 1 ), It is also possible to arrange at least one dampening unit with corresponding dampening rollers and at least one corresponding dampening solution source, but this is not the case in the preferred embodiment described here.

The form cylinder 01 and the transfer cylinder 03 are preferably arranged one above the other, more preferably such that at least one axis of rotation 13 of the forme cylinder 01 and a rotation axis 14 the transfer cylinder 03 lie in a common vertical plane. A substrate 04 At least at the point where he is using the transfer cylinder 03 in contact is preferably transported horizontally. The following is based on this arrangement, 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 therefore should not be limited to this particular arrangement. In addition, the paraphrasing that at least the axes of rotation 13 ; 14 in a common plane also include the case that at least the two axes of rotation 13 ; 14 do not lie exactly parallel and thus are not mathematically exactly in a plane, for example because one of the axes of rotation 13 ; 14 because of a Diagonalregistereinstellung slightly skewed to the other axis of rotation 13 ; 14 lies.

At least one roller and / or a cylinder is preferred 01 ; 02 ; 03 interchangeable, more preferred are all rollers and cylinders 01 ; 02 ; 03 the printing unit interchangeable, especially the form cylinder 01 and the transfer cylinder 03 , This makes it possible, for example, different form cylinder 01 on the one hand differ in the printed image to be printed, on the other hand, but may also have a different circumference and thereby open up the possibility of printing in different formats without having space on, for example, a web-shaped substrate 04 would remain unnecessarily blank. So can a smaller print image with a forme cylinder 01 be printed smaller scale, while a web-shaped substrate 04 and with a constant format of the forme cylinder 01 with a smaller print image a larger blend would be incurred. The transfer cylinder 03 is in the case of an exchange of the forme cylinder 01 also exchanged, since the scopes of form cylinder 01 and transfer cylinder 03 agree or at least have to be in an integer ratio.

To form cylinder 01 and transfer cylinder 03 To use different formats in the printing press, the press on various properties and devices.

The printing machine preferably has at least one positioning device for at least the forme cylinder 01 and the transfer cylinder 03 because of a positioning of the axes of rotation 13 ; 14 of the form cylinder 01 and the transfer cylinder 03 must be adapted to the diameter of these cylinders 01 ; 03 be exchanged for those with other scopes. The positioning device thus serves, despite different usable scopes of the cylinder 01 ; 03 Distances and gaps between form cylinder 01 , Transfer cylinder 03 and impression cylinder 02 to optimize.

To cylinder 01 ; 02 ; 03 and / or to be able to replace rollers, these are preferably by means of bearing receptacles 32 , which is preferred as a folding camp 32 and more preferably as controllable quick-lock bearings 32 are formed, rotatably fixed in the printing press. Such quick release bearings 32 ensure a safe and fast exchange of rollers and / or cylinders 01 ; 02 ; 03 , For a mechanical replacement of rollers and / or cylinders 01 ; 02 ; 03 are preferably controllable quick-lock bearings 32 arranged, since in this way such an exchange can take place automatically and thus accurately and quickly and operators are not exposed to any danger in handling of more than 100 kg heavy components of the printing press. Problems with not completely open folding warehouses 32 be 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, cylindrical pins 17 of the cylinder 01 ; 02 ; 03 in camp shots 32 held. The bearing shots 32 can be opened and / or closed manually and / or automatically and / or locked or unlocked. This allows the at least one cylinder 01 ; 02 ; 03 be fixed rotatably in a certain predetermined position. Both have both cylindrical pins 17 in each case at least one bearing, preferably designed as a roller bearing, for example a ball bearing or a roller bearing, whose outer component, immovable in printing operation, for example outer ring, in each case a bearing receiver 32 fixed, for example, can be clamped. In this way, the corresponding cylinder 01 ; 02 ; 03 around a fixed axis of rotation 13 ; 14 rotate. The bearing shots 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 ; 02 can be moved. As a result, depending on the adjustment changes of a diagonal register can be made and / or it can be an entire cylinder 01 ; 02 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 preferably Linearverstelleinrichtun come conditions for use.

At least one adjusting device preferably has frame-fixed strips or rails or guide rails, in which, for example, at least one slide is movably mounted via sliding elements. The at least one carriage has at least one bearing receiver 32 on, in which at least one, with the cylinder pin 17 one cylinder each 01 ; 02 ; 03 firmly connected, roller bearing is arranged. By means of corresponding adjustment devices and, if appropriate, corresponding drives, this makes it possible to move the cylinder 01 ; 02 ; 03 depending on the number and version of the adjustment to move in different directions and thus distances between cylinders 01 ; 02 ; 03 and / or rollers. This is preferably possible under machine control. A shift of the cylinder 01 ; 02 ; 03 along its axis of rotation 13 ; 14 this 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 are provided, which are more preferably capable of machine-controlled and possible without intervention of an operator rollers and / or cylinders 01 ; 02 ; 03 expand and / or install. It should be noted that this is via an exchange of rollers and / or cylinders 01 ; 02 ; 03 The same can also be said for a single expansion or a single installation of one or more corresponding components. The at least one handling device 301 So serves the purpose of exchanging rollers and / or cylinders 01 ; 02 ; 03 to 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 301 having a transport of the rollers and / or cylinders 01 ; 02 ; 03 by a series of vertical and / or horizontal movement steps from the printing press into at least one warehouse or at least one transport vehicle 303 lifts or at least one cylinder changing device may have at least one pivot arm, the rollers and / or cylinders 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 press and / or can pivot back. Such a trolley 303 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 cylinders 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.

As preferred both each forme cylinder 01 as well as each transfer cylinder 03 each with its own drive 16 , for example in the form of a motor 16 , has, must, this drive 16 when changing the corresponding cylinder 01 ; 03 be taken into account. The drives 16 , for example, as position-controlled synchronous motors 16 may be formed with permanent magnets are preferably coaxial with the cylinders 01 ; 03 arranged. Preferably, the engines remain 16 during a change of cylinders 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 601 between cylinders 01 ; 03 and engine 16 be executed separable. Preferably, such a separation is at least also machine-controlled feasible. More preferably, the printing press on at least one Seitenregistereinstellvorrichtung, while a circumferential register by the separate drive 16 at least the forme cylinder 01 No additional mechanical components required. The side register adjuster is preferred with the coupling between the engine 16 and form cylinder 01 arranged cooperatively, as after a change of the forme cylinder 01 usually a new setting of the page register is required.

At least the form cylinder 01 or the transfer cylinder 03 or both the form cylinder 01 as well as the transfer cylinder 03 have at least one, but preferably in each case two Diagonalregistereinstellvorrichtungen.

It is not only possible in principle, forme cylinder 01 and / or transfer cylinder 03 to exchange for those with a different scope, but it is also possible, corresponding cylinder 01 ; 03 to be provided with various lifts or sleeves, so-called sleeves, each having a same inner diameter and different outer diameter. These sleeves are on a cylinder 01 ; 03 pushed and fixed on 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 tempered are formed to control a respective surface temperature of at least the lateral surface and / or to be able to regulate. For this purpose, at least the form cylinder 01 and / or the transfer cylinder 03 with an inflow and an outflow and a flow-through Be provided part, so that they are flowed through by a liquid temperature control and in this way in the printing operation of at least the forme cylinder 01 and / or the transfer cylinder 03 can be kept at a constant temperature on its lateral surface.

In addition, components of the printing unit are in the printing operation with adjustable cylinders 01 ; 03 In contact are also movably arranged, as in a format change and especially in 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 an equal distance or contact pressure to the forme cylinder 01 regardless of the extent of the forme cylinder. The same applies to other contact points where one of the cylinders 01 ; 03 is involved.

It be pointed out that the term "parallel" in Previous and below as well as in parallel as well as is to be understood antiparallel.

A handling device 301 a printing press is designed such that it has at least two cylinders in a first operating state 01 ; 03 can move back and forth between different positions. One of the positions is preferably a service position, for example a position in which the cylinders 01 ; 03 not in contact with each other but both still on their cylinder pin 17 with the respective bearing shots 32 in contact with which they are also in contact in a printing company. In such a position, the cylinder 01 ; 03 and the bearing shots 32 for example, as described above be brought by means of carriages along rails. This is the handling device 301 capable of the cylinders 01 ; 03 to move in two different directions, 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 has a component in the horizontal direction, which is larger than a possible component in the vertical direction and of which the other direction has a component in the vertical direction, which is greater than a possible component in the horizontal direction. In one embodiment, with the handling device 301 in a second operating state, only one cylinder 01 ; 03 be moved at a time, for example because of a changed position of at least two cylinder shots 334 ; 336 the handling device 301 relative to each other only one cylinder 01 ; 03 is accessible and another cylinder out of range of corresponding cylinder shots 334 ; 336 the handling device 301 lies.

In the following, a first embodiment of a handling device 301 described. The handling device 301 has a sled 304 on which one along a rail 306 by means of a first drive 307 , for example via a spindle 308 , Can be moved substantially in a horizontal direction. It is of course also possible instead of a spindle 308 having drive 307 a belt drive 307 , a chain drive 307 or a linear drive 307 to use or instead of the exemplified electric drive 307 a pneumatic or hydraulic drive 307 to use or the sled 304 mechanically driven by a gear or gears and / or racks. The same applies to the other drives described below 307 ; 326 , On the sledge 304 is still a second rail 309 with a second slide 311 arranged, which for example by means of a drive 312 over a spindle 313 along the rail 309 can be moved.

At the second sled 311 are still pivot axes 314 ; 316 for example, hinges 314 ; 316 arranged over which support arms 317 ; 318 each rotatably mounted with the carriage 311 are connected. The pivot axes 314 ; 316 can, for example, centric in the support arms 317 ; 318 be arranged ( 2 ), Coaxial to the pivot axes 314 ; 316 are on the support arms 317 ; 318 respective gears 319 ; 321 attached, which with a common drive gear 322 engage. The drive gear 322 is in this case for example via a shaft 323 rotatable on a plate 324 attached, with the plate 324 For example, fixed to the pivot axes 314 ; 316 connected is. Furthermore, the gear 322 with a drive 326 connected, whereby when driving the drive 326 the support arms 317 ; 318 over the meshing gears 319 ; 321 ; 322 can be pivoted parallel to each other in a certain angular range. To limit the angular range, it may be provided, corresponding, not shown in the figures limit stops on the carriage 311 and / or on at least one support arm 317 ; 318 and / or at another appropriate location.

Furthermore, at the respective ends of the support arms 317 ; 318 respective common lifting arms 327 ; 328 attached, each via rotary axes 329 ; 331 respectively 332 ; 333 with the carrying arms 317 ; 318 are connected and thereby with the support arms 317 ; 318 form a parallelogram. The lifting arms 327 ; 328 continue to have at their ends respective cylinder shots 334 ; 336 on, for example, substantially circular segment-shaped and / or semicircular 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-level, not shown machine control, it is thus possible, the lifting arms 327 ; 328 in different positions to pivot, for example, in a first, also in 2 shown, in which the upper lifting arm 327 is brought into a forward from the pointing 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 Hebearm 328 placed in 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 can be brought into an example middle position, in which both cylinders 01 ; 03 can be handled.

An exact location of the lifting arms 327 ; 328 and thus also the cylinder shots 334 ; 336 to each other, especially in the middle position, depends on the geometric arrangement of the cylinder 01 ; 03 in the printing unit, this is exemplified below as standing perpendicular to each other. A process of handling the upper cylinder 01 ; 03 by means of the handling device 301 is described below and is also schematic in the 3a to 3e shown. It corresponds to the second operating state of the handling device described above 301 , For better understanding here are in 2 shown elements, such as drive elements, not shown.

Here is the Rebeinrichtung 301 at the beginning of a cylinder change initially still in a rest position, which the handling device 301 for example, during normal printing operation occupies and in which in particular the lifting arms 327 ; 328 outside an area of influence of the cylinders 01 ; 03 are located. The cylinders 01 ; 03 are already in a required for a cylinder change service position, in which the cylinder 01 ; 02 ; 03 are offset from each other and have a fixed distance to each other ( 3a ), The cylinders 01 ; 03 are at this time with their respective cylinder pin 17 in their respective bearing shots 32 stored, at which time, for example, already a fixation by means of a respective component, not shown, for example, as a folding bearing 32 trained camp admission 32 can be solved, so that the cylinder 01 ; 03 are removable.

In a subsequent step, the upper lift arm 327 by means of the drive 326 over the support arms 317 ; 318 move in a forward position, which ensures that in the further course of action, only the upper cylinder 01 ; 03 from his warehouse 32 can be taken while the lower cylinder 01 ; 03 out of reach of the handling device 301 lies. 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 into a rear position and thus pivoted away from the work area ( 3b ),

In a subsequent step, the handling device will now be 301 on her sled 304 along the rail 306 by means of the drive 307 in a direction M in a first working position, in which the cylinder receiving 334 of the lifting arm 327 below the cylinder pin 17 of the cylinder to be removed 01 ; 03 located ( 3c ), The direction M is substantially perpendicular to a plane that the assumed as parallel axes of rotation 13 ; 14 the cylinder 01 ; 03 contains, and has at least one component, the of the handling device 301 away and on one of the rotation axes 13 ; 14 to assign. A subsequent lifting of the carriage 311 the Rebeinrichtung 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 shots 334 to come to rest and the cylinder 01 ; 03 from the storage shots 32 is lifted out ( 3d ), The direction N thus preferably points essentially vertically upwards. This is the cylinder 01 ; 03 at least as far as the stock photographs 32 singled out that in a subsequent step without any problems by means of the drive 307 in the direction M out of the printing unit in a removal position can be moved out ( 3e ),

A procedure of handling a lower cylinder 03 ; 01 by means of the handling device 301 show schematically and by way of example 4a to 4f , This procedure also corresponds to the second operating state of the handling device described at the outset, and also in these figures, for the sake of clarity, those in FIG 2 shown elements partly not shown.

The handling device 301 is at the beginning of a cylinder change initially still in a rest position, which the handling device 301 during normal printing operation occupies and in which in particular the lifting arms 327 ; 328 outside the sphere of influence of the cylinders 01 ; 03 are located and the cylinders 01 ; 03 as already described, in a service position required for a cylinder change the one in which the cylinders 01 ; 03 are offset from each other and have a fixed distance to each other ( 4a ), The cylinders 01 ; 03 are at this time with their respective cylinder pin 17 in their respective bearing shots 32 stored, at which time, for example, already a fixation by means of a respective component, not shown, for example, as a folding bearing 32 trained camp admission 32 can be solved, so that the cylinder 01 ; 03 are removable.

In a subsequent step, the lower lift arm 328 by means of the drive 326 over the support arms 317 ; 318 moved in a forward position, which ensures that in the further course of action, only the lower cylinder 03 ; 01 from his warehouse 32 can be taken ( 4b ), For this purpose, the support arms 317 ; 318 pivoted against the direction L, at the same time the upper lifting arm 327 is pivoted into a rear position with and thus pivoted away from the work area.

It may be necessary in this case, in a subsequent step, the lifting arms 327 ; 328 along the rail 309 Lower counter to the direction N so far that the lifting arm 328 or at least the cylinder mount 336 below the cylinder pin 17 and / or below the bearing receiver 32 passes, whereby the lifting arm 328 easily under the cylinder pin 17 can be handled ( 4c ),

In a subsequent step, the handling device will now be 301 on her sled 304 along the rail 306 by means of the drive 307 in the direction M in a first working position, in which the cylinder receiving 336 of the lifting arm 328 below the cylinder pin 17 of the cylinder 03 ; 01 located ( 4d ), A subsequent lifting of the carriage 311 the handling device 301 along the rail 309 in the direction of N by means of the drive 312 , causes the cylinder pin 17 of the cylinder 03 ; 01 in the cylinder shots 336 to come to rest and the cylinder 03 ; 01 from the storage shots 32 is lifted out ( 4e ), This is the cylinder 03 ; 01 at least as far as the stock photographs 32 he emphasized that in a subsequent step, by means of the drive 307 can be moved out in the direction of M from the printing unit in a removal position and at the same time not with the still in his camp recording 32 located cylinder 01 ; 03 collided or obstructed by it ( 4f ),

A sequence of handling both cylinders 01 ; 03 by means of the handling device 301 , the initially mentioned first operating state of the handling device 301 corresponds, show schematically and by way of example 5a to 5d , Also in these figures, for clarity, partly in 1 not shown elements shown.

The Rebeinrichtung 301 is at the beginning of a cylinder change initially still in a rest position, which the handling device 301 during normal printing operation occupies and in which in particular the lifting arms 327 ; 328 outside the sphere of influence of the cylinders 01 ; 03 are located and the cylinders 01 ; 03 as already described, in a service position required for a cylinder change, in which the cylinders 01 ; 03 are turned off each other and their axes of rotation 13 ; 14 have a fixed distance to each other ( 5a ), The cylinders 01 ; 03 are at this time with their respective cylinder pin 17 in their respective bearing shots 32 stored, at which time, for example, already a fixation by means of a respective component, not shown, for example, as a folding bearing 32 trained camp admission 32 can 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 required for the removal of both pressure rollers 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 will now be 301 on her sled 304 along the rail 306 by means of the drive 307 in the direction of M in a working position, in which the cylinder shots 334 ; 336 the lifting arms 327 ; 328 each below the respective cylinder pin 17 the cylinder 01 ; 03 are located ( 5b ),

A subsequent lifting of the carriage 311 the handling device 301 along the rail 309 in the direction of N by means of the drive 312 on the one hand causes the cylinder pin 17 the cylinder 01 ; 03 in the respective cylinder shots 334 ; 336 to come to rest and the cylinders 01 ; 03 from their respective storage shots 32 be lifted out ( 5c ), Here are the cylinders 01 ; 03 at least as far from the respective bearing shots 32 singled out that in a subsequent step without any problems by means of the drive 307 in the direction M from the printing unit in a removal position can be moved out ( 5d ),

It should be noted that the working positions of the carriages mentioned in the respective exemplary descriptions 304 ; 311 along their respective rails 306 ; 309 depending on the cylinder or cylinders to be removed 01 ; 03 can be different and each example monitored and / or controlled by means not shown sensors and / or control devices. Such sensors and / or controllers may be connected to a machine controller.

Another embodiment of a handling device 301 is described below. Here, in contrast to the previous embodiments, the lifting arms 327 ; 328 as short lifting arms 327 ; 328 executed, which each have a cylinder recording 334 ; 336 and which via respective push rods 337 338 at respective linear drives 339 ; 341 are attached. The linear drives 339 ; 341 are here on the sled 311 a vertical displacement device attached, which at least one rail 309 , a sled 311 and a drive 312 having, wherein the carriage 311 by means of the drive 312 via a drive shaft 313 for example, a spindle 313 along the rail 309 can be moved ( 6 ),

This makes it possible by operating either the linear drive 339 or 341 only one of the cylinders 01 ; 03 essentially according to an already described process from its bearing receptacle 32 to remove or both cylinders 01 ; 03 at the same time. It is expedient at least the vertical distance of the linear drives 339 ; 341 so choose that it is essentially the vertical distance of the cylinder 01 ; 03 in their service position.

With the handling device 301 So you can choose a cylinder as needed 01 ; 03 or two cylinders 01 ; 03 , in other conceivable embodiments also more than two cylinders 01 ; 02 ; 03 be automatically brought without intervention of an operator from a first position, such as 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, such as a replacement position or removal position or other service position. In accordance with the reverse procedure can of course also cylinder 01 ; 02 ; 03 be moved 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 by means of an external handling device, for example a trolley 303 , a swivel arm or a pulley, are removed and against other cylinders 01 ; 02 ; 03 be replaced or it can also be carried out only cleaning or a printing plate change or a blanket change.

In a further embodiment of the handling device 301 are all lifting arms 327 ; 328 relative to each other rigidly arranged and can only be moved together. It follows that all cylinders 01 ; 03 that with the handling device 301 can be moved, can only be moved together ( 7 ), This embodiment is recommended when predominantly or always all cylinders 01 ; 03 should be replaced at the same time. The execution then essentially corresponds to that in 6 illustrated embodiment, with the difference that the linear actuators 339 ; 341 omitted and instead the cylinder shots 334 ; 336 are arranged immovably to each other. Their use is analogous to the case described above, which is also in 5a to 5d is shown. Also in this case it is possible to use only one of the cylinders 01 ; 03 exchange, for example, by all cylinders 01 ; 03 means of handling device 301 be brought into their appropriate 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 attached cylinder 01 ; 03 back to his service position and / or returned to his working position. In 7 is also another embodiment of the drive 312 represented, in this case, at least one hydraulic cylinder or a pneumatic cylinder whose movements via a lever 342 in a vertical movement of the carriage 311 and thus the associated lifting arms 327 ; 328 is converted.

For this purpose, the dolly 303 moved to a specific removal position between two printing units and, for example via positioning 354 , for example, positioning mandrels 354 or conically shaped and possibly extendable centering pins 354 on the trolley 303 , which engage in corresponding sockets on the printing press aligned with the printing unit, so that, for example, lifting arms 356 and in particular those at the ends of the lifting arms 356 attached cylinder mountings 357 at a suitable height and in a suitable position relative to the cylinders 01 ; 03 are located. A subsequent method of at least one displacement device 358 on which the lifting arms 356 are fixed, moves the lifting arms 356 and in particular the cylinder receptacle 357 in a direction O in the printing unit and preferably to the respective bearing receptacles 32 ( 7 ), wherein the direction O is preferably perpendicular to a rotation axis 13 ; 14 a cylinder 01 ; 02 ; 03 has and at least one component, that of the displacement device 358 on a cylinder 01 ; 02 ; 03 to assign. In one embodiment, the printing press has other or additional means than the carriages around the cylinders 01 ; 03 be brought from a position intended for the printing operation in the appropriate service position or removal position. Such means then have, for example cylinder receivers 334 ; 336 on, in which the cylinders 01 ; 03 can be stored.

In a preferred embodiment, the trolley 303 Locking elements, with which it can be fixed at least for the duration of the cylinder change with the respective printing unit, for example, by the positioning 354 have additional locking elements such as electrically or pneumatically actuated clamping elements or screw elements, which after a successful positioning of the trolley 303 be pressed to the printing unit. In a further preferred embodiment of the trolley 303 can with the positioning and locking of the trolley 303 with the printing unit an electrical and / or pneumatic connection by means of a plug connection 359 be prepared, whereby, for example, a power supply and / or a control of the trolley 303 befindli Chen movement elements can be done via a higher-level machine control, not shown. In one embodiment, the trolley 303 an electric drive and preferably also a separate memory for electrical energy or a separate power generator, preferably the trolley 303 but connected via an electrical connection, for example via a drag chain with a supply unit and the higher-level machine control.

The bearing shots 32 are preferred as quick release bearings 32 trained and can be further preferably opened via the machine control, so that no manual intervention of an operator is necessary. It can also be a handling device 301 be located directly on the press, the dissolved cylinder 01 ; 03 brings into a service position or removal position. In another embodiment, for releasing the bearing receivers 32 at the ends of the lifting arms 356 respective actuators 361 attached, which depending on the design of the bearing mounts 32 for example, electric screwdrivers 361 , Solenoids 361 or pneumatically actuated linear adjuster 361 can have. The actuators 361 In one embodiment, at least one part may be used 362 a camp recording 32 pick up and hold, especially if a bearing recording 32 several detachable parts such as screws and / or half shells 362 having. The parts thus held 362 the camp admission 32 are then after inserting another cylinder 01 ; 03 in the warehouse 32 of the printing unit again with the remaining parts in the printing unit 363 the camp admission 32 connected and the camp admission 32 is by means of the actuators 361 locked, causing the replaced cylinder 01 ; 03 is fixed in the printing unit in its desired position.

After opening the bearing receivers 32 and optionally after a displacement of the cylinder 01 ; 03 in a corresponding service position or removal position are from the stock recordings 32 removable or removed cylinder 01 ; 03 by means of the lifting arms 356 taken from the printing unit by the cylinders 01 ; 03 in at the ends of the lifting arms 356 attached cylinder mountings 357 be picked up and moved out in a subsequent step from the printing unit opposite to the direction O in a specific end position ( 8th ), For safe transport and / or safe transfer of the cylinders 01 ; 03 to ensure are preferred on the cylinder receivers 357 corresponding locking devices arranged. It is both conceivable that the lifting arms 356 be used to the cylinders 01 ; 03 to be taken from corresponding service positions or removal position, as well as that corresponding devices of the printing press, the cylinder 01 ; 03 keep in the service position or removal position, these cylinders 01 ; 03 active on the cylinder mounts 357 passed, for example, by lowering these devices. This can be the cylinder shots 357 move, but they can also be arranged stationary at least during the transfer.

After removal or transfer of the cylinder 01 ; 03 are the lifting arms 356 with the in the cylinder shots 357 located cylinders 01 ; 03 completely outside the printing unit, so after loosening the connector 359 and the positioning devices 354 and / or a lock 354 the trolley 303 can be moved out of the space between the successive printing units. In a subsequent step, the trolley is now 303 with the cylinders located on it 01 ; 03 to a respectively provided for the printing unit supply magazine 364 drove and the cylinders 01 ; 03 there in designated shots 366 or cylinder shots 366 stored. For this purpose, the dolly 303 in a similar manner as in the printing unit to the storage magazine 364 moved to a certain position and by means of positioning 354 aligned and optionally with the storage magazine 364 locked. The pictures 366 preferably have locking devices to secure transport and / or safe storage of the cylinder 01 ; 03 to ensure.

The storage magazine is designed for example as a rotating system, wherein, for example, on a conveyor belt 367 , for example, as a chain strap 367 is formed, a certain number of cylinder shots 366 is appropriate. The distance between the cylinder mounts 366 each other is suitably chosen so that it is the distance of the cylinder 01 ; 03 in the printing unit in its removal position or service positions ( 15 ),

For storing the cylinder 01 ; 03 becomes the conveyor belt 367 moved in one direction so far, the vacant positions 368 ; 369 at the height of in the shots 357 the lifting arms 356 of the trolley 303 located cylinder 01 ; 03 so that with a movement of the lifting arms 356 in a direction Q in the storage magazine 364 into the cylinders 01 ; 03 in the storage magazine 364 can be stored. The direction Q preferably has relative to the trolley 303 in the same direction as the previously mentioned direction O The supply magazine 364 here has at least two different cylinder recordings 366 for cylinders 01 ; 03 on, making a choice between Zylin countries 01 ; 03 with different diameter and / or different print image is made possible. For example, should two cylinders 01 ; 03 be replaced at the same time, so the supply magazine 364 an integer multiple of two cylinder recordings 366 on, but at least four. It is expedient that the storage magazine 364 more than four cylinder shots 366 For example, six, eight or more, which provides greater flexibility of an entire system by allowing multiple different cylinder diameters to be accessed quickly and easily (FIG. 15 and 16 ),

It can also be provided that only a common storage magazine 364 is provided for all printing units of the printing press. In this case, the supply magazine 364 all desired cylinders 01 ; 03 can record for all printing units.
