Description

The invention relates to a drive of a punching cylinder according to the preamble of claim 1 and a method for adjusting a drive of a punching cylinder according to claim 17.

When processing corrugated board, a sheet of corrugated board goes through several processing steps. The sheets are printed or painted, for example, and their mass and/or shape and/or contour can be changed by shaping devices. A particularly suitable printing process is flexographic printing. Flexographic printing is characterized by a form cylinder with a flexible printing form. Rotary processing methods such as rotary punching are often used for shaping due to their speed advantages.

Rotary punches usually have punching units with a punching cylinder and an anvil cylinder. A punching die with punching tools or knives is usually arranged on the punching cylinder, which during operation processes the substrate and also comes into contact with the anvil cylinder. The counter-die cylinders have elastic and resistant coatings or die-cut coverings. When changing jobs, the dies have to be exchanged. Changing devices for cutting cylinders are used to quickly return the rotary die cutter to an operational state.

through the U.S. Patent No. 6,138,544 a changing device for a punching cylinder is known. The arrangement of the cylinders in this changing device is referred to in the document as a planetary arrangement, since two punching cylinders are arranged around an anvil cylinder. The cylinders are arranged on a disk and the two die-cutting cylinders can be exchanged by rotating the disk.

Furthermore, the GB 2 406 069 A a similar arrangement of the anvil cylinder and die cylinder. The two punching cylinders are rotatable about an axis of rotation and can be exchanged by rotation.

Furthermore, the DE 10 2014 205 880 B3 a punching device with means for changing punching cylinders. The tool change should be faster. For this purpose, the punching device has two holders for receiving punching cylinders. The anvil cylinder can be adjusted to both die cylinders. For this purpose, the counter-die cylinder is set off from one die-cutting cylinder and placed on the other.

The U.S. 7,175,578 B2 shows another possibility to exchange the punching cylinder. Two punching cylinders are adjusted using linear guides. A punching cylinder can be moved in the horizontal direction from a maintenance position. The die-cutting cylinder to be changed and the counter-die-cutting cylinder are adjusted from a vertical position in such a way that the two die-cutting cylinders are on one level in the vertical direction. Both punching cylinders are then shifted horizontally. The new die-cutting cylinder then takes the position of the previous cylinder.

Furthermore, cylinder changing devices are known in printing presses. through the WO 98/50235 A2 For example, a device for changing a forme cylinder in a rotary printing machine, in particular a gravure printing machine, is known. Changing a cylinder is very easy thanks to the use of a steady rest. A forme cylinder can be lifted out of the side frame by means of a carriage and moved in the direction of an elevator. The forme cylinder can then be moved there. The elevator is moved to introduce a new forme cylinder and then the new forme cylinder is guided to the storage.

When changing forme cylinders or for the purpose of rotating them relative to one another, the forme cylinders can be decoupled from their drive. For example, the WO 01/87605 A1 such a coupling of a forme cylinder with a corresponding drive in a printing press. In this document, the engine as a whole is shifted for coupling and/or for decoupling. The motor is adjusted via a threaded spindle.

The object of the invention is to create a drive for a punching cylinder and a method for adjusting a drive for a punching cylinder.

The object is achieved according to the invention by the features of claim 1 or by the features of claim 17.

The advantages that can be achieved with the invention are, in particular, that an improved punching unit has been created.

The punching unit preferably has a drive for driving the punching cylinder. The drive has a motor with a rotor and a stator, which are arranged to be axially adjustable relative to one another. The drive thus serves various functions. The relative adjustability can be used on the one hand for side register adjustment and on the other hand To release the punching cylinder from a clutch and/or to remove it, so that the punching cylinder can be changed in a simple manner. In particular, the punching cylinder can easily be removed horizontally from its punching position. This is possible because the motor is designed as a synchronous motor with a permanently excited magnetic field on the rotor. For this purpose, the rotor has at least one permanent magnet. In this configuration, the rotor can be easily adjusted relative to the stator.

Structurally, adjusting only the rotor has the advantage that the drive can be mounted firmly on a housing support and additional linear guides, on which the entire drive is moved, can be dispensed with. It must therefore only be ensured that the rotor can be adjusted axially. This is preferably done by a plain bearing.

In a preferred embodiment, the rotor is adjustable relative to the stator. The rotor can be adjusted either together with the punching cylinder or without the punching cylinder. When the rotor is adjusted together with the die-cutting cylinder, its side register can be adjusted. When adjusting without the punch cylinder, a clutch can be moved out of the way so that the punch cylinder can be easily changed. In addition, after the cylinder has been changed, a clutch can simply be brought back into contact with the new punching cylinder.

In a preferred embodiment, the rotor and stator are adjusted relative to one another by means of an actuator. This enables an automated adjustment process. For this purpose, the actuating drive is preferably connected to the rotor. The actuator is preferably designed as a pneumatic and/or electric and/or preferably an electromechanical drive. The electromechanical drive impresses with its durability and reduced complexity.

In a preferred embodiment, a clutch is arranged between the motor and the punching cylinder. By releasing the coupling, the connection between the drive and the punching cylinder can be separated. The coupling can preferably be released by means of a pressure medium. A sufficiently high force to release the clutch can thus be applied in a simple manner. Particularly preferably, the pressure medium can be fed through a bore through the axis of the rotor of the clutch. A rotary inlet is preferably used for this purpose.

The centering of the rotor is preferably ensured by mounting the punching cylinder, in particular in a hub of the punching cylinder. By coupling the clutch, the rotor is preferentially centered. This has the advantage that there is no need for an additional bearing in the motor. A spherical roller bearing enables corresponding mobility.

The punch cylinder can preferably be changed by a changing device in an improved manner. In addition, a pre-equipment of a punching cylinder is made possible by the changing device. The time-consuming task of changing a die can already take place during a current die-cutting process thanks to pre-setup. By using the changing device, another die-cutting cylinder can be prepared while a die-cutting cylinder is in operation. When the job changes, the new cutting die is already attached to the new cutting cylinder, which can then be moved to the cutting position quickly and fully automatically. The design of the changing device ensures a high degree of automation with increased safety. Furthermore, the construction of the changing device avoids additional costs due to a simple design and the saving of superfluous components.

In addition, the die-cutting cylinder can be changed fully automatically with the changing device. Inline in a sheet processing machine with application units, such as printing or coating units, the sheet processing machine achieves increased efficiency with regard to the time required for a job change. The application units also have devices for simplified changing of the cylinders of the application units, for example. An inline, fully automatic device for changing can thus contribute to significantly more efficient operation of the entire machine. The time-consuming process of changing a die can thus already take place in the machine while a current die-cutting process is still running. When the job changes, the new die is already attached to the die-cutting cylinder, and the die-cutting cylinder can then be moved to the die-cutting position quickly and fully automatically.

When changing jobs, not only the punching tools but also the order forms have to be changed in the processing machine. In a preferred configuration, the processing machine has redundant order aggregates, ie more order aggregates than are required in a normal order job. The combination of redundant order units in conjunction with the device for changing the die-cutting cylinders means that job changes can be made much faster. The application units are preferably designed in such a way that they can be switched on and/or off quickly and fully automatically. The The combination of the device for changing the die-cutting cylinders and the redundant job units makes it possible to pre-set up both processing steps and significantly reduces the time until the next job. However, the use of an increased number of application units is not limited to the fact that they can be used for pre-setup. These can also be used, for example, to carry out special orders. For example, an increased number of colors, in particular special colors, can be applied in this way.

In a preferred embodiment, the punching unit has a device for locking the punching cylinder in the punching position. As a result, the punching cylinder can be held in the punching position in a simple and secure manner and can also be released in a simple manner. The punching cylinder is preferably pressed from the processing point, preferably vertically, pointing away, preferably from below, against a frame and/or an element fixed to the frame. The punching cylinder experiences loads from the processing point during punching. These come about, for example, in that the punching cylinder cyclically presses and/or hits the anvil cylinder and/or the substrate. Because the die-cutting cylinder is pressed against the frame from the opposite side or from below, the impacts do not affect the locking of the die-cutting cylinder, but act on the solid frame. This leads to improved power dissipation with reduced stress and reduced wear. The detent is connected to a drive, whereby the detent can be actuated and raised automatically. The releasing or fixing of the lock can thus be synchronized with the changing process of the punching cylinders via a controller.

In a preferred embodiment, the bearings and the bearing seats are attached to the punching cylinders. As a result, the punching cylinder can be removed more easily. The punching cylinder then does not have to be removed from the bearings in the axial direction before changing.

In a further preferred embodiment, the punching cylinder is decoupled from its drive by means of a clutch for changing. This has the advantage that the punching cylinder can be changed and the drive remains in position. On the one hand, this saves an additional drive and, on the other hand, the movement sequence of the die-cutting cylinder change is significantly simplified. The punching unit and the changing device can then be designed in a simplified manner and take up less space.

In a preferred embodiment, the clutch is actuated with an actuator. For this purpose, the actuating drive preferably adjusts either the entire drive of the punching cylinder parallel to the axis of rotation or only part of it. In addition to actuating the clutch, the actuator can preferably be used to adjust the side register of the drive of the punching cylinder. The drive is preferably designed as a torque motor with a rotating component, a rotor, and a rigid component, a stator. The actuator then preferably adjusts only one of the two components, preferably the rotor, in the axial direction parallel to the axis of rotation of the punching cylinder. In this embodiment, both functions can thus be implemented with just one actuator.

In a further preferred embodiment, the punching cylinders are guided in guides by means of a groove. This significantly increases the security of the changing process. The punching cylinders remain in the guides and shifting in the axial direction is prevented. This prevents the cylinders from coming loose from the guides and increases safety. Safe operation for a plant operator is thus guaranteed at all times.

In a preferred embodiment, the cylinder pins each have at least one hub. Such a hub preferably has the groove for securely guiding the punching cylinders in the guides. Furthermore, the hub has the bearings for storing the punching cylinder. The hub preferably has an adapted contact surface for fixing and/or releasing the punching cylinders by means of the locking device.

Furthermore, the simple cylinder change is achieved in that the punching cylinder can be removed in a particularly simple manner, predominantly horizontally, from a punching position and/or changing position. A connecting straight line between the positions of the cylinders is then preferably inclined at less than 30° to a horizontal one.

In a preferred embodiment, the punching unit is designed in such a way that the at least one anvil cylinder is and/or remains in a working position or in a parked position during replacement. This simplifies the changing process, since only the punching cylinders have to be moved. Furthermore, the changing process is accelerated since the anvil cylinder can be brought back into the working position quickly.

Preferably, the device for changing punching cylinders to, preferably two Füh struggled up. This small number of guides enables a cylinder change with a particularly simple movement sequence.

Furthermore, the changing device has a waiting position for moving the cylinders past one another. In this way, the complexity of changing the cylinder can be reduced to a minimum. For this purpose, the waiting position is preferably arranged outside of a direct guide path between the changing position and the maintenance position.

In a preferred embodiment, the waiting position is arranged slightly below or at the same level in the vertical direction or above the punching position and/or the changing position and/or the extending position. As a result, the cylinders can be changed in a particularly simple manner and with a structurally simple design. By arranging the waiting position above the changing position and/or the extended position, in particular at a distance from the extended position, it is achieved that a punching cylinder change takes place in a simple manner, since both cylinders can be moved past one another particularly easily. For this purpose, for example, only a vertical guide has to be expanded. In this way, a cylinder can be temporarily stored in the waiting position and the other cylinder can simply be guided past it. Additional guides and further levels for arranging the cylinders can thus be dispensed with.

In a preferred embodiment, the maintenance position is at a significantly lower level than the punching position of the punching cylinder. As a result, a die can be changed or exchanged particularly easily. The die can then be changed easily and without a lifting device. The punching cylinder is also much more accessible in the maintenance position than in the punching position. At the punching position, a wide variety of devices such as sensors, suction devices, counter-punching cylinders, etc. interfere. It is particularly advantageous for the punching cylinder to be arranged at a distance from other cylinders in this position. For example, auxiliary devices can then also be brought up to the punching cylinder in a simple manner.

In a preferred embodiment, the punching unit has a device for locking the punching cylinder in the punching position. As a result, the punching cylinder can be held in the punching position easily and securely.

In a further preferred embodiment, the punching cylinders are transported on a transport system. In a preferred embodiment, only two transport elements are required for a cylinder change. This is achieved by using a common carrier with two holding places for the cylinders. There is also a horizontal transport element. With this arrangement, the complete cylinder change can be realized with just two adjustable elements.

Another advantage that can be achieved with the invention is that the punching cylinder can be removed from its punching position in a particularly simple manner. The transport device, which guides the sheets to the processing point, can be adjusted or raised in a simple manner by means of an adjustment device. The punching cylinder can then be removed from the punching position particularly easily, preferably horizontally. The transport device can easily be adjusted depending on the position of a punching cylinder. This enables a simple movement sequence when changing the cylinder.

The adjusting device preferably has a drive for adjusting the transport device. As a result, the transport device can be adjusted automatically and moved out of the way if necessary.

In a preferred embodiment, the adjustment process of the transport device is synchronized with the device for changing the punching cylinders, preferably mechanically and/or electrically. In a particularly preferred embodiment, the adjustment process is mechanically coupled to the device for changing the punching cylinders via a contact surface of the transport device. The mechanical coupling leads to a particularly simple and safe mode of operation for changing the cylinder. The mechanical coupling ensures in particular that the transport device is guided out of the guide path of the device for changing at the right moment.

In a preferred embodiment, the adjustment device has a particularly simple structure for adjusting the transport device. The transport device is preferably guided on a guide, as a result of which simple and safe adjustment or lifting of the transport device is ensured. The transport device preferably rests against a stop in the working position with its own weight. In order to adjust the transport devices, it is then only necessary to work against the transport device's own weight. The transport device can easily be lifted up in the vertical direction.

In a preferred embodiment, the guide in which the transport device is guided is designed as a common guide with the adjustment device. A frame and/or housing, which sits in the guide, is preferably arranged on the transport device. The movement when changing cylinders is synchronized with one another via a common contact surface between the transport device or frame and the device for changing. In the process of changing the punching cylinders, a transport element and/or a carrier is moved and adjusts the transport device or raises the transport device. This movement preferably takes place only in one guide, namely the vertical guide. This ensures that the cylinder can be easily removed from the punching position and that the transport device is quickly brought back into the correct position or working position after the cylinder has been changed. The return movement preferably takes place by lowering the contact element of the adjusting device. Due to the transport device's own weight, it is preferably lowered again as well.

A processing machine 01 is preferably embodied as a printing machine 01 and/or as a shaping machine 01, in particular a punching machine 01. Printing press 01 is embodied as a flexographic printing press 01, for example.

Processing machine 01 is preferably referred to as printing machine 01 if it has at least one printing unit 614 and/or at least one printing unit 600, in particular regardless of whether it has other units for processing substrate 02. For example, a processing unit designed as a printing press 01 processing machine 01 also has at least one further such unit 900, for example at least one shaping unit 900, which is preferably embodied as a punching unit 900, more preferably as a punching device 900. Processing machine 01 is preferably referred to as a shaping machine 01 if it has at least one shaping mechanism 914 and/or at least one shaping unit 900, in particular regardless of whether it has other units 600 for processing substrate 02. Processing machine 01 is preferably referred to as punching machine 01 if it has at least one punching unit 914 and/or at least one punching unit 900 and/or at least one punching device 900, in particular regardless of whether it has other units 600 for processing substrate 02. For example, a processing machine 01 configured as a shaping machine 01 or punching machine 01 also has at least one additional unit 600 for processing substrate 02, for example at least one printing unit 600 and/or at least one printing unit 614.

In a preferred embodiment, processing machine 01, in particular a sheet processing machine 01, preferably comprises a unit 100 embodied as sheet feeder 100 and/or at least one application unit 614 for applying at least one printed image to substrate 02. If processing machine 01 has at least one printing unit 614 and/or at least a printing unit 600 on the one hand and at least one shaping unit 914 and/or at least one shaping unit 900 on the other hand, it is therefore configured both as a printing press 01 and as a shaping machine 01. If processing machine 01 has at least one printing unit 614 and/or at least one printing unit 600 on the one hand and at least one punching unit 914 and/or at least one punching unit 900 and/or at least one punching device 900 on the other hand, it is therefore suitable both as a printing machine 01 and as a shaping machine 01, in particular punching machine 01.

The processing machine 01 is preferably embodied as a sheet-fed processing machine 01, i.e. as a processing machine 01 for processing sheet-type substrate 02 or sheets 02, in particular sheet-type printing material 02. For example, the sheet-fed processing machine 01 is configured as a sheet-fed printing machine 01 and/or as a sheet-forming machine 01 and/or as a sheet-fed punching machine 01 educated. Processing machine 01 is more preferably embodied as a corrugated cardboard sheet processing machine 01, i.e. as a processing machine 01 for processing sheet-type substrate 02 or sheets 02 made of corrugated cardboard 02, in particular sheet-type printing material 02 made of corrugated cardboard 02. The processing machine 01 is more preferably embodied as a sheet-fed printing machine 01, in particular as a sheet-fed printing machine 01 Corrugated sheet printing machine 01, i.e. as a printing machine 01 for coating and/or printing sheet-type substrate 02 or sheets 02 made of corrugated board 02, in particular sheet-type printing material 02 made of corrugated board 02. Printing machine 01 is embodied, for example, as a printing machine 01 that operates using a printing forme-based printing process.

Unless an explicit distinction is made, the term sheet-shaped substrate 02, in particular a printing material 02, specifically sheet 02, is used here to mean any flat substrate 02 or any substrate 02 that is present in sections, i.e. also substrates 02 that are in the form of panels or plates, i.e. also panels or plates, be included. The sheet-like substrate 02 or sheet 02 defined in this way is made of paper or cardboard, for example; H. formed as paper or cardboard sheets, or by sheets 02, panels or plates made of plastic, cardboard, glass or metal. More preferably, substrate 02 is corrugated cardboard 02, in particular corrugated cardboard sheets 02. The at least one sheet 02 is preferably embodied as corrugated cardboard 02. The thickness of a sheet 02 is preferably understood to mean a dimension orthogonal to a largest area of the sheet 02. This largest area is also referred to as the main area. The thickness of the sheets 02 is, for example, at least 0.1 mm, more preferably at least 0.3 mm and even more preferably at least 0.5 mm. In the case of sheets of corrugated cardboard 02 in particular, significantly greater thicknesses are also common, for example at least 4 mm or even 10 mm and more. Corrugated cardboard sheets 02 are comparatively stable and therefore not very flexible. Corresponding adjustments to the processing machine 01 therefore make it easier to process thick sheets 02.

The respective, preferably at least one, sheet 02 is preferably made of paper or cardboard. According to DIN 6730, paper is a flat material consisting essentially of fibers, mostly of vegetable origin, which is formed by draining a fibrous suspension on a sieve. This creates a fiber felt that is then dried. The mass per unit area of paper is preferably at most 225 g/m2. According to DIN 6730, cardboard is a flat material consisting essentially of fibers of plant origin, which is formed by dewatering a fibrous suspension on one or between two screens. The fiber structure is compacted and dried. Cardboard is preferably made from cellulose and/or by gluing or pressing together. Before cardboard is preferably designed as solid cardboard or corrugated cardboard 02. In the above and below, corrugated cardboard 02 is cardboard made of one or more layers of corrugated paper that is glued to one layer or between several layers of another preferably smooth paper or cardboard. Preferably the grammage of paperboard is over 225 g/m2. In the above and in the following, the term board refers to a paper fabric that is preferably coated on one side and preferably has a mass per unit area of at least 150 g/m 2 and at most 600 g/m 2 . Cardboard preferably has high strength relative to paper.

The processing machine 01 preferably has a plurality of units 100; 300; 600; 700; 900; 1000 on. A unit is preferably understood to mean a group of devices that work together functionally, in particular to be able to carry out a preferably self-contained processing operation on sheets 02. For example, at least two and preferably at least three and more preferably all of the units 100; 300; 600; 700; 900; 1000 as modules 100; 300; 600; 700; 900; 1000 formed or at least assigned to one such. A module is to be understood in particular as a respective unit or a structure made up of several units, which preferably has at least one means of transport and/or at least one controllable and/or regulatable drive of its own and/or as an independently functioning module and/or each manufactured separately and/or is formed as a machine unit or functional assembly mounted on its own. A unit or module's own controllable and/or regulatable drive means, in particular, a drive that serves to drive the movements of components of this unit or module and/or that serves to transport substrate 02, in particular sheets 02, through it respective unit or module and/or through at least one effective area of this respective unit or module and/or which is used to directly or indirectly drive at least one component of the respective unit or module intended for contact with sheets 02. Preferably, the separate controllable and/or regulatable drive of a unit or module is designed to drive movements of components of this unit or module and/or to cause substrate 02 to be transported and/or at least one component of the respective unit intended for contact with sheets 02 or Module trained directly or indirectly driving. These drives of the aggregates 100; 300; 600; 700; 900; 1000 of processing machine 01 are preferably embodied as position-controlled electric motors in particular.

Each unit preferably has 100; 300; 600; 700; 900; 1000 at least one drive controller and/or at least one drive controller, which the respective at least one drive of the respective unit 100; 300; 600; 700; 900; 1000 is assigned. The drive controls and/or drive controllers of the individual units 100; 300; 600; 700; 900; 1000 can preferably be operated individually and independently of one another. The drive controls and/or drive controllers of the individual units 100; 300; 600; 700; 900; 1000 are and/or can be linked to one another and/or to a machine controller of processing machine 01 in terms of circuitry, in particular by means of at least one BUS system, in such a way that coordinated control and/or regulation of the drives of several or all units 100; 300; 600; 700; 900; 1000 of processing machine 01 is and/or can be carried out. The individual aggregates 100; 300; 600; 700; 900; 1000 and/or in particular modules 100; 300; 600; 700; 900; 1000 of processing machine 01 can therefore be operated and/or operated in an electronically coordinated manner, at least with regard to their drives, in particular by means of at least one electronic master axis. An electronic master axis is preferably specified for this purpose, for example by a higher-level machine controller of processing machine 01. Alternatively or additionally, the individual units 100; 300; 600; 700; 900; 1000 of processing machine 01, at least with regard to their drives, for example, are mechanically synchronized and/or can be synchronized with one another. The individual units 100; 300; 600; 700; 900; 1000 of processing machine 01, however, are mechanically decoupled from one another, at least with regard to their drives.

The spatial area provided for the transport of substrate 02, which the substrate 02 occupies at least temporarily if it is present, is the transport route. The transport path is preferably defined by at least one device for guiding the substrate 02 when the processing machine 01 is in an operating state.

If there are deviations in the printing and/or punching quality, the sheet deflector 1001 can be controlled by means of the signals from the sensors 726, 728, 916 and the sheets can be deflected in the transport path and thus conveyed onto the discharge stack. Sheet processing machine 01 also has a plurality of sheet arrival sensors 622; 922 on. Furthermore, over time, external changes in the print length result in the punch length. This change can also be detected by the sensors and the cylinders can then be controlled and/or regulated with the signals.

There is a need to change the die-cutting cylinders 901 in a die-cutting unit 900 in an improved manner. For this purpose, the punching unit 900 has a device for changing 950 the punching cylinders 901 . A punching cylinder 901, which is in a punching position 981 during operation, can be exchanged for another punching cylinder 903. The device for changing 950 includes the components of the punching unit 900 on changing the cylinder 901; 903 are involved and/or required. The punching unit 900 preferably has a suction device 966 for sucking off waste parts or dust.

The punching cylinders 901; 903 can be used in the device for changing 950 in several positions 981; 982; 985; 986; 987 be arranged. When punching, the punching cylinder 901 is arranged in the punching position 981. During operation of the processing machine 01, the punching knives come into contact with the punching layer 906 of the counter-punch cylinder 902 in the punching position 981. This position 983 of the counter-punch cylinder 902 is referred to as the working position 983 of the counter-punch cylinder 902.

The at least one punching cylinder 901 can be and/or is arranged in a changing position 982. The punching cylinder 901 can be transferred from the punching position 981 to a changing position 982 . For this purpose, at least one lock 951 of the punching cylinder 901 is opened. The at least one punching cylinder 901 is ready for removal in the changing position 982. The change position 982 is preferably spaced apart from the punching position 981 and more preferably arranged below the punching position 981.

In a preferred embodiment, the punching cylinder 901 is operatively connected to a drive 962 . The drive 962 is preferably fixed to the frame and/or housing on the housing 963 of the punching unit 900, preferably by means of a carrier 974. The drive 962 advantageously includes a motor 931, in particular a torque motor 931, with a rotor 994 and a stator 995. The motor 931 is designed as a synchronous motor 931. The rotor 994 has a permanently excited magnetic field. For this purpose, the rotor 994 preferably has at least one permanent magnet. For this purpose, the rotor 994 preferably has at least one winding with at least one, preferably several, permanent magnets. The rotor 994 or runner of the synchronous motor 931 has poles made of permanent magnets on its circumference (in particular alternating in the circumferential direction). The stator 995 has windings opposite the permanent magnets for generating magnetic fields by electrical energy. A moving rotating magnetic field is generated in the stator 994 . The rotor 994 and the stator 995 are preferably arranged to be adjustable relative to one another, preferably axially. A high power density is achieved by this design of the motor 931, in particular with the permanent magnets. The use of gear ratios therefore becomes unnecessary. This eliminates inaccuracies in the drive train and wear and tear on mechanical elements such as gears.

By axially adjusting the rotor 994, the punching cylinder 901; 903 can be completely removed from a clutch 968 and brought back into contact. In addition, due to the relative adjustability of rotor 994 and stator 995, the side register can be adjusted. Furthermore, the power of the drive 962 changes due to the relative adjustment. The rotor 994 is axially displaced from a coupled position to an uncoupled position. The rotor 994 preferably moves between 50 mm and 200 mm, more preferably about 160 mm. To adjust the side register, the rotor 994 is moved out of the coupled position with the punching cylinder 901; 903 moves. Sensors on the machine can be used to generate a signal for the actuator 996 via the machine control. Based on this signal, the actuator 996 is adjusted accordingly to correct the side register. The punching cylinder 901, 903 is preferably only moved a few millimeters to centimeters for register setting.

The drive 962 has at least one guide 969 for this purpose. The drive 962 is particularly preferably designed as a torque motor 931. A rotary encoder monitors the position of the cylinder 901; 903. To remove the punching cylinder 981, the clutch 968 is released. Alternatively, the entire drive 962 can also be adjusted parallel to the axis of rotation of the punching cylinder 901, preferably by means of an actuator 996.

Preferably, only the rotor 994 of the actuator 996 is arranged parallel to the axis of rotation of the punching cylinder 901, by means of the actuator 996, adjustable and/or adjustable. The rotor 994 can be adjusted either with the punching cylinder 901 or without the punching cylinder 901.

In particular, the side register can then be adjusted by the relative displacement of rotor 994 to stator 995. In this case, the rotor 994 can be adjusted with the punching cylinder 901. On the other hand, the rotor 994 can also be adjusted without the punching cylinder 901. On the one hand, this is the case when a clutch is released and the clutch 968 is pulled off or removed from the punching cylinder 901 or when the clutch 968 is connected to a new punching cylinder 901; 903 is to be coupled. The clutch 968 is preferably removed from the cylinder journal when changing the punching cylinder. This exposes the punch cylinder 901 for easy horizontal removal from its changing position. After changing the punching cylinder 901, the new punching cylinder 903 is coupled by axially adjusting the rotor 994.

The rotor 994 is mounted in the motor 931. The motor 931 preferably has a spherical roller bearing 930 for mounting. This is preferably adjusted with the rotor 994 in the axial direction by means of the actuator 996 . A plain bearing 999 is also used to allow the rotor 994 to move axially. The sliding bearing 999 is preferably arranged on the end face in the direction of the clutch 968.

The rotor 994 is preferably centered via the bearing 990 of the punching cylinder 901; 903; in particular in the hub 970 of the punching cylinder 901; 903, guaranteed. By coupling the clutch 968, the drive 968 or the rotor 994 is centered. The spherical roller bearing 930 enables the centering movement. The drive 968 is thus supported by the spherical roller bearing 930 and the bearing 990 of the punching cylinder 901 .

The device for changing 950 has the coupling 968 for coupling and/or for decoupling the punching cylinder 901; 903 to and/or from the driver 962 for driving one of the punch cylinders 901; 903 on. An actuator 996 is preferably connected to the drive 962 . The drive 962 is preferably connected to the punching cylinder 901 via a coupling 968 . Preferably, the clutch 962 when changing the punching cylinder 901; 903 can be opened and the punching cylinder 901 can thus be decoupled from its drive 962. The clutch 968 is preferably arranged between the drive 962 or the motor 931 and the punching cylinder 901. In the engaged state, the clutch 968 is axially connected to the punch cylinder 901; 903 movable.

In an advantageous embodiment, the coupling 968 has a clamping sleeve 973 with prestressed clamping elements. Such clamping elements can be star disks, for example. The clutch 968 is designed to be detachable, preferably with a pressure medium, for example by means of hydraulics or hydraulically. For this purpose, the pressure medium can be supplied to the clutch 968 through the axis of the rotor 994 . The rotor 994 preferably has a central bore 998 through which the pressure medium reaches the clutch 968 . The bore 998 preferably extends through the entire rotor 994. The pressure medium can thus be supplied or conveyed in a simple manner to actuate the clutch 968, for example via a rotary inlet 997 through the axis or the bore 998 to the clutch 968.

Alternatively, the clutch 968 can also be a clutch 968 that can be shifted in some other way. For example, clutch 968 may be embodied as a cone, disc, electromagnetic, or fluid clutch. In a first embodiment, the punching cylinder 901 remains in position or does not change its position during transfer from the punching position 981 to the changing position 982.

The at least one actuator 996 can preferably adjust drive 962 or part thereof, preferably rotor 994, in a direction parallel to the axis of rotation of punching cylinder 901 and/or is arranged to be adjustable. The actuator 996 is preferably in operative connection with the rotor 994 and can adjust it in the axial direction relative to the stator 995 . The rotor 994 can preferably be adjusted by at least 100 mm, more preferably by 160 mm, in the axial direction.

In a preferred embodiment, the drive 961 of the counter-punch cylinder 902 also has a synchronous motor, preferably one that is excited by permanent magnets. A gearing can then also be dispensed with for the anvil cylinder 902 as well.

In a first embodiment, the punching cylinder 901 remains in position or changes its position only slightly during transfer from the punching position to the changing position. In this case, the changing position is characterized in that only the locking device 951 is open or loosened.

The device for changing 950 has a lock 951 for fixing the punching cylinder 901 in the punching position 981 and/or for releasing it from the punching position 981. The at least one punching cylinder 901 can be and/or is arranged in a released state of the locking device 951 in the changing position 982. The at least one punching cylinder 901 can be and/or is arranged in the punching position 981 when the locking device 951 is in a fixed state.

In a further embodiment, the position of the punching cylinder 901 changes during transfer from the punching position 981 to the changing position 982. This is particularly the case when the detent 951 pushes the punching cylinder 901 into one position and is then released. The locking device 951 is particularly preferably arranged pressing the punching cylinder 901 from below against a contact surface, preferably in the form of a half-shell, in a housing wall 963 or in the frame. The contact surface is preferably adapted to the shape of the punching cylinder 901 and/or at least adapted to a guide element 971 on the cylinder journal. Such a guide element 971 is preferably a groove 971 on a hub 970 which is placed on the cylinder journal. In the embodiment with the detent 951 from below, the punching cylinder 901 falls or moves downwards in the vertical direction V when transferring from the punching position 981 to the changing position 982 . In particular, the punching cylinder 901, in particular its groove 971, is then in a changing position 982 in a guide 959. The punching cylinder 901 then preferably moves only a few centimeters. Preferably, the die-cutting cylinder moves less than 20 cm, more preferably less than 10 cm. At least in the embodiment with the locking device 951 from below and the change of position during transfer to the changing position, the anvil cylinder 902 has an actuator. The counter-punch cylinder 902 can be transferred from a punching position 981 to a parked position 984 by means of the actuating drive.

The lock 951 is preferably in operative connection with a drive 962 . The drive 962 presses or pulls a holding element from below against the contact surface 971 of the punching cylinder 901 via a lever. 903 in the punching position 981. The punching cylinder 901 rises and is pressed from below against the housing wall and/or the frame. The detent 951 is the punch cylinder 901; 903 arranged fixed from below against a frame 963 and/or an element 963 fixed to the frame and/or the housing 963. The lock 951 can then be released again by the drive 952 . By releasing the lock 951, the punching cylinder 901 can be transferred from the punching position 981 to the changing position. In this embodiment described here, the punching cylinder 901 is locked from below. However, locking from the side or from above is also possible. The locking device 951 particularly preferably acts pointing away from the shaping point 909 or processing point 909, in particular perpendicularly. For example, locking from above is advantageous in the case of a rotated punching unit. The housing 963 has a coordinated contact surface, preferably in the form of a half-shell, for receiving the punching cylinder 901 in the punching position 981. The matched shape preferably means a contact surface with a similar curvature to the corresponding contact surface of the punching cylinder 901, in particular the hub 971. On the one hand, the punching cylinder 901 preferably has a contact surface for clamping. The detent 951 has another matching contact surface. Preferably, the contact surface of the detent 951 is also adapted to the shape of the punching cylinder 901; 903, or the shape of the hub 970. The contact surface of the locking device 951 is then arranged opposite the contact surface of the housing 963 or of the frame 963 for a good clamping effect. Alternatively, the two contact surfaces can also be arranged diagonally opposite one another. In a preferred embodiment, the punching cylinder 901 or the additional punching cylinder 903 is arranged in the changing position 982. In this changing position 982, the respective punching cylinder 901; 903 arranged at the end of the horizontal guide 959. The horizontal guide 959 preferably has a half-shell at the end. In this half-shell is the punching cylinder 901; 903 on. Furthermore, a further recess, preferably in the form of a half-shell, is preferably arranged above. In this, the punching cylinder 901; 903 now pressed. For this purpose, the lock 951 lifts the punching cylinder 901; 903 from below and pushes the punch cylinder 901; 903 in the recess above. The recess is designed in such a way that the punching cylinder 901; 903 is then held in position. The contact surface of the detent 951 holds the punch cylinder 901; 903 then also in position due to the coordinated shape, preferably the half-shell shape. The respective punching cylinder 901; 903 is then held in the punching position by the catch 951, in particular its contact surface, and/or by the recess in the frame 963 and/or the housing 963 and/or the recess at the end of the horizontal linear guide 959. The recesses are preferably designed in such a way that they have a shape that is matched to the contact surface of the hub 970 . In particular, this configuration ensures that the punching cylinders 901; 903 possible.

In a further preferred embodiment, the position of the punching cylinder 901 changes when it is transferred from the punching position 981 to the changing position 982. The punching cylinder 901 preferably moves only a few centimeters. Preferably, the die-cutting cylinder moves less than 20 cm, more preferably less than 10 cm. In a preferred embodiment, the anvil cylinder 902 is predominantly adjustable in the vertical V direction. The parked position 984 is a position at which the counter-punch cylinder 902 is brought out of contact with the punch cylinder 901 . The counter-punch cylinder 902 thus essentially remains in its working position 983. The counter-punch cylinder 902 is preferably only turned off to such an extent that the counter-punch cylinder 902 is out of contact even when the punch cylinder 901 is arranged in the changing position 982. Preferably, an actuator drives the anvil cylinder 902 only between 15 cm and 30 cm. The actuator preferably has a stroke of at most 50 cm, more preferably at most 30 cm.

The punching cylinder 901 has at least one bearing 990 at each axial end, preferably on the cylinder journal. The at least one punching cylinder 901 has at least one bearing 990 at each axial end. The bearing 990 is preferably arranged on the punching cylinder 901 in such a way that it moves with the punching cylinder 901. The position of the bearing 990 differs in the changing position 982 from the position in the punching position 981. A bearing 990 is preferably arranged at each axial end of the punching cylinder 901. In particular, each punching cylinder 901; 903 has a hub 970 at each of its ends in the axial direction A.

The punching cylinder 901 preferably has at least one hub 970 on at least one of the cylinder journals. The hub 970 is preferably designed in such a way that it facilitates the movement of the punching cylinder 950 in the axial direction in the guides 958; 959 limited. For this purpose the hub 970 has two shoulders which form a groove 971 . The hub 970 has a surface that can be fixedly connected to the frame and/or a housing wall 963 by the detent 951 . The locking device 951 preferably has a half-shell shape, which is adapted to the contact surface of the hub, in particular the groove 971. In addition, the housing wall 963 preferably also has a tuned half-shell to accommodate the contact surface of the 970 hub. Thus, the punching cylinder 901 is fixed in the vertical and horizontal directions at the punching position 981 by the detent 951 . The punching cylinder 901 is fixed in the axial direction by raising the hub 970 . Accordingly, these also act as guide elements in the guides 958; 959. The bearing 990 is preferably arranged in the hub 970. Furthermore, for example, a detent 951 is briefly opened by means of the actuating drive 996 in order to set the lateral register.

The device for changing 950 has to move the punch cylinder 901; 903 a transport system 955 on. This includes transport elements 965, 956, which the punching cylinder 901; 903 and transport it along the guideways and/or to the different positions.

Another position that the punching cylinder 901 can assume is the extended position 985. The at least one punching cylinder 901 can be transferred from the changing position 982 to an extended position 985. For this purpose, the at least one punching cylinder 901 is preferably removed from the changing position 982 and guided along a guide 959.

The punching cylinder 901 can preferably be removed predominantly horizontally from the changing position 982 and transferred to the extended position 985. In this context, predominantly horizontal means in particular a direction with a predominantly horizontal component. This also includes inclined guides with this formulation. The punching cylinder 901 can preferably be transferred on a linear guide 959 from the changing position 982 to the extended position 985.

The predominantly horizontal guide 959 is preferably implemented by means of at least one transport element 965. Before releasing a lock 951, a transport element 965 is preferably arranged under the punching cylinder 901. The transport element 965 preferably has a coordinated shape and thus holds it on the transport element 965. For this purpose, the transport element 965 receives the punching cylinder 901 in the changing position 982 and is guided on a guide rail by means of a drive. A distance between the punching position 981 and the changing position 982 is preferably smaller than a distance between the punching position 981 and the extended position 985.

The device for changing 950 for transferring the punching cylinder 901 from the changing position 982 to the extended position 985 preferably has at least one transport element 965. A transport element 965 is preferably arranged on each side of the housing 963 . This preferably has a half-shell for holding the punching cylinder 901. The transport element 965 can be moved, preferably horizontally, on a guide rail. However, the transport element 965 can also follow curved guide paths. By moving the transport element 965, the punching cylinder 901 is moved along the guide 959, preferably predominantly horizontally, more preferably completely horizontally.

The extended position 985 is preferred, the position at which the direction of the punching cylinder 901 changes. The punching cylinder 901 is preferably transferred at the extended position 985 from the transport element 965 of the horizontal guide 959 to the transport element 956 of the vertical guide 958. i.e. the extended position 985 is preferably a position where the guide paths of the vertical guide 958 and the horizontal guide 959 intersect. For this purpose, the two transport elements are arranged in different positions or offset from one another in the axial direction, i.e. over the width of the machine, and can engage in one another and take over the punching cylinder 901 . From there, the punching cylinder 901 can then be adjusted in the vertical V direction.

Furthermore, a punching cylinder 901; 903 can be and/or is arranged in a maintenance position 987 for set-up and/or maintenance. In this maintenance position 987, the punching cylinder 901 can be serviced and, for example, prepared for a new punching job. For example, a punching tool can be exchanged for a new one. For example, the punching tools consist of half-shells with punching tools, such as punching knives, arranged thereon. The maintenance position 987 is preferably arranged in a vertical direction V below the punching position 981 and/or the changing position 982. More preferably, the punching cylinder 901 is then at a height that is comfortable for an operator. This has the advantage that the punching cylinder 901 can be prepared for the next punching job in a position that is at a height that is easy for an operator to reach. The die-cutting cylinder 901 is also removed from interfering elements and can thus be easily reached from the surrounding pages.

Another position in which the punching cylinders 901; 903 is a waiting position 986. The waiting position 986 is used to move two cylinders 901; 903 and is at least outside of a guide path of a punching cylinder 901. The guide path is the direct transport path between the changing position 982 and the maintenance position 987. This is defined by the guides 958; 959. This can achieve that a punching cylin the 901 and another punching cylinder 903 in the guides 958; 959 can be guided past each other. Thus, a punching cylinder 901 can be exchanged with another punching cylinder 903 in the punching position 981. The process can also take place in reverse order. One of the punching cylinders 901; 903 is arranged in the waiting position 986 and the other punching cylinder 901; 903 can then be guided past it.

In a preferred embodiment, the waiting position 986 is located at a similar height or above the changing position 982 and/or the punching position 981. In this case, a similar height means, in particular, a position in the vertical direction V which is essentially at the same position in the vertical direction V. This means in particular that the waiting position 986 is arranged at most only 100%, more preferably at most 50% or 20%, lower than a diameter D901 of the punching cylinder 901. The diameter D901 is preferably the distance from the furthest dimensions, including any knife lengths, of the punching cylinder 901. In order to save space, the at least one punching cylinder 901 in the waiting position 986 is preferably above the punching cylinder 901; 903 arranged, but the waiting position 986 is only so far above that it is outside the guide path and the other punching cylinder 901; 903 can be guided past this.

In a preferred embodiment, the punching cylinder 901 is removed from the changing position 982 along a removal direction E and guided to the extended position 985 . Furthermore, the waiting position 986 is within or even more preferably above two envelope tangents of the punching cylinder 901. These upper tangent 974 and lower tangent 975 are preferably at the opposite points of the outer edges of the punching cylinder 901 and are preferably arranged parallel to the removal direction E. The removal direction E is preferably defined by the guide 959. In a preferred embodiment, the removal direction E is oriented horizontally. However, in the case of an inclined or curved guide 959, the removal direction E can also be inclined relative to the horizontal. The removal direction E preferably runs through the changing position 982 and the extended position 985 or is defined by these two positions. The removal direction E can thus be determined in particular in the case of curved guides 959 . The waiting position 986, in particular its center point, is preferably inside or above the tangent and preferably spaced apart so that the cylinder 901 to be removed and the new cylinder 903 do not get in each other's way. The position of the positions preferably means the position of the axis of a cylinder that would lie at this position.

The device for changing 950 preferably has two guides 958; 959 on. The two guides 958; 959 of the device for changing 950 as linear guides 958; 959 trained. A guide 959 is preferably designed as a predominantly, more preferably completely, horizontal linear guide 959. The other guide 958 is preferably designed as a predominantly, more preferably completely, vertical guide 958. Preferably, predominantly here means a larger directional component in the respective horizontal or vertical direction. In another embodiment, guides 958; 959 also be curved.

The transport system 955 preferably has at least one transport element 965 for moving the punching cylinders 901; 903 and preferably at least one transport element 956; 960 for mainly vertically moving the punching cylinders 901; 903 on. These transport elements 965; 956; 960 are designed, for example, as carriages with holding arms. The waiting position 986 is preferably arranged on the vertical guide 958 . The predominantly vertical guide 958 then has either two transport elements 956; 960 or two transport elements 956; 960 on a common transport device 972. In a particularly simple structural configuration, the two transport elements 956 of the predominantly vertical guide 958 are arranged together on a common transport device 972, in particular a carrier 972 and/or carriage 972. Then, by moving the transport device 972, both punching cylinders 901; 903 are moved in a predominantly, more preferably completely, vertical direction V. The guide 958 preferably has two transport elements 956; 960, in particular a first vertical transport element 956 and a second vertical transport element 960. The first and second transport elements 956; 960 are preferably movable with a common transport device 972 on a preferably predominantly, more preferably completely, vertical guide rail 957.

Furthermore, the punching cylinders 901, 903 can and/or are also arranged at least briefly in intermediate positions during the change. This is due, for example, to the fact that e.g. B. move the transport elements under the cylinders to take them over, whereby these can be easily lifted. In addition, the punching cylinder 901, 903, which is arranged in the maintenance position 987, can in principle be on the upper or on the lower transport element 956; 960 be discarded. This is then driven to the right height for waiting.

More preferably, the at least one punching cylinder 901 and the at least one additional punching cylinder 903 have an axis of rotation 976. The individual positions can be geometrically connected via straight lines 977; 978; 979 of the axes of rotation 976 are described. The axes of rotation 976 run axially through the punching cylinders 901; 903. They can also be called the central axis. In particular, these connecting lines are 977; 978; 979 then the shortest connections between the axes of rotation 976 of the punching cylinders 901; 903 if they are in the individual positions. A shortest connecting straight line 977 between the axis of rotation 976 of the punching cylinder 901; 903 in the punching position 981 and the axis of rotation 976 of the punching cylinder 901; 903 in the extended position 985 is inclined less than α=30°, more preferably less than α=15°, to a horizontal plane 988. Inclined means an inclination between an angle α and a horizontal plane 988. This also applies to the changing position 982. This differs little from the punching position 981. Here, too, there is a shortest connecting straight line 979 between the axis of rotation 976 of the punching cylinder 901; 903 in the changing position 982 and the axis of rotation 976 of the punching cylinder 901; 903 in the deployed position 985 inclined less than 30° to a horizontal plane 988. The horizontal plane 988 preferably runs parallel to a floor. Furthermore, the waiting position 986, the maintenance position 987 and the extended position 985 are preferably arranged on a vertical guide 959. i.e. the positions are aligned with one another at a vertical 989 and are preferably offset in the vertical V direction. Vertical 989 is preferably parallel to vertical direction V. Preferably, vertical 989 passes through the centers of cylinders 901; 903 in the maintenance position 987, extended position 985 and waiting position 986. The 3 positions are preferably arranged directly one above the other. A waiting position 986 is preferably arranged above the extended position 985 and a maintenance position 987 is arranged below the extended position 985 . However, in another embodiment, the waiting position 986 may be adjacent to one of the other positions. In principle, it is only important that the waiting position 986 is outside of the direct guide path between the maintenance position 987 and the punching position 981. However, the waiting position 986 is preferably above, since this enables a particularly preferred and simple structural design of the device for changing 950. A shortest connecting straight line 978 between the axis of rotation 976 of the punching cylinder 901; 903 in the extended position 985 and the waiting position 986 less than 30 °, more preferably less than 15 °, inclined to the vertical 989 and / or vertical direction V. Furthermore, a shortest connecting straight line 980 between the axis of rotation 976 of the punching cylinder 901; 903 is inclined less than 30° to a vertical and/or vertical direction V in the deployed position 985 and the maintenance position 987 . The maintenance position 987 is preferably arranged in the vertical direction V below at a distance from the changing position 982 .

The punching unit 900 with the changing device 950 is advantageously arranged inline in a sheet processing machine 01 with order units. These aggregates also have, for example, devices for simplified changing of the cylinders of the application works. An inline, fully automatic die changer can thus contribute to a significantly more efficient overall machine.

In a preferred embodiment, the processing machine 01 has more order units 600 than are required in a normal order job. This means that machine 01 has at least two application units 600, it being possible for one of the application units 600 to be used at least as a redundant application unit 600. In the case of multi-color printing, four application units 600 are usually used. These four application units 600 are preferably printing units 600. Additional units 600 designed as paint application units 600 can also be present. The processing machine 01 more preferably has four additional application units 600 for multi-color printing. These four application units 600 can usually be serviced and/or set up while the other units 600 are in operation. These four additional application units 600 can be used at least as redundant application units. Alternatively, these additional job units 600 can also be used for special print jobs. For example, special colors and/or lacquers can also be applied with the additional application units 600 .

The punching cylinder 901 is changed by the changing device 950 with the method described below.

When machine 01 is in operation, punching cylinder 901 and counter-punching cylinder 902 are located in punching position 981 and working position 983, respectively. From time to time the punching cylinder 901 has to be changed or exchanged. In a first step, the anvil cylinder 902 is turned off from the punching cylinder 901 and transferred from a punching position 981 to a turned off position 984 . The anvil cylinder 902 is preferred for this purpose mainly in the vertical direction V, preferably down. During the change, the anvil cylinder 902 remains in this position and does not have to be moved.

In a further step, the punching cylinder 901 is moved from the punching position 981 to the changing position 982. In a preferred embodiment, the punching position 981 and the changing position 982 are different positions. The lock 951 is released for the transfer. In a preferred embodiment, the punching cylinder 901 is decoupled from the drive 962 by the clutch 968 before it is transferred from the punching position 981 to the changing position. The punching cylinder 901 is pressed in the punching position 981 by means of the locking device 951 pointing away from the shaping point 909 against a frame wall 963 and/or housing wall 963. In the preferred embodiment, the punching cylinder 901 is positioned above the forming station 909 . Therefore, the lock 951 presses the punching cylinder 901 from below against the frame 963 and/or the housing wall 963. The lock 951 lifts the cylinder 901; 903 and presses it against an adapted contact surface, preferably a half-shell.

The further punching cylinder 903, which is to be exchanged with the current punching cylinder 901, is located in the maintenance position 987. Preferably, the punching cylinder 903 in the maintenance position 987 can easily be prepared for the next punching job. For this purpose, a half-shell with the punching knives is preferably exchanged.

The two punching cylinders 901; 903 are now in the guides 958; 959 passed each other. For this purpose, one of the punching cylinders 901; 903 temporarily stored and/or temporarily stored in the waiting position 986. Either the punching cylinder 901 is moved from the changeover position 982 and/or the punching position 981 to the waiting position 986, or the additional punching cylinder 903 is moved from the maintenance position 987 to the waiting position 986. Only one of the cylinders 901; 903 must be brought out of the guide path and is therefore temporarily stored in the waiting position 986 for the cylinders to be moved past one another.

In the embodiment with the further punching cylinder 903 in the waiting position 986, the adjustment takes place according to the following steps. The other punching cylinder 903 is moved from the maintenance position 987 to the waiting position 986. This is preferably done by adjusting the additional punching cylinder 903 predominantly vertically, preferably along the primarily vertical guide 958. In particular, a transport element 956 is moved in the vertical direction V with the cylinder on the guide rail 957 and thus transports the additional punching cylinder 903 to the waiting position 986 The transport element 956 is preferably positioned at the extended position 985 and waits for the punching cylinder 901 to take over.

After the counter-punch cylinder 902 has been switched off and the lock 951 has been released, the punch cylinder 901 is guided from the changing position 982 and/or the punching position 981, preferably on the guide 959, into the extended position. For this purpose, the punching cylinder 901 preferably rests on the contact surfaces of the transport element 965 provided for this purpose. This is guided with the punching cylinder 901 on a guide rail and stopped in the extended position 985. The punching cylinder 901 is moved in one step from a punching position 981 or changing position 982 to an extended position 985. The punching cylinder 901 is thereby moved predominantly horizontally from the punching position 981 to the extended position 985.

In the extended position 985, the punching cylinder 901 is transferred to the transport element 956 of the preferably vertical guide 959. For example, the transport element 956 moves from below to the punching cylinder 901 and takes over the punching cylinder 901 in which the transport element 956 lifts the cylinder 901 slightly so that the transport element 956 of the predominantly horizontal guide can be moved out. There may be a few intermediate positions that are due to the construction and are required to transfer the cylinders from one transport element to another.

Alternatively, the punching cylinder 901 can also be temporarily stored in the waiting position 986. The punching cylinder 901 is then transferred from the extended position 985 to the waiting position 986. For example, this is what happens when the changeover position 982 is at the same height in the vertical V direction. The punching cylinder 901 is then either transferred directly, predominantly horizontally, from the changing position 982 to the waiting position 986. Alternatively, the punching cylinder 901 is removed from the extended position 985 and then taken over predominantly vertically, for example with the further transport element 956, and transferred to the waiting position 986. In this variant, a transport element 956 takes over the punching cylinder 901 in the extended position 985 and moves it into the waiting position 986.

The other punching cylinder 903 is then guided to the extended position 985. For example, depending on the embodiment, guided to the extended position 985 by means of the transport system 955 . Depending on the embodiment, the first or the second vertical transport element 956, 960 is used for this purpose. With the help of the waiting position 986 it is thus achieved that the two cylinders can be moved past one another. The further punching cylinder 903 can then be moved from the extended position 985, preferably predominantly horizontally, to the changing position 982. The horizontal transport element 965 is preferably used for this purpose. At the changing position 982 the further punching cylinder 903 is then fastened or fixed again by means of the locking device 951 . The additional punching cylinder 903 is preferably transferred to the punching position 981 for this purpose. The counter-die cylinder 902 is then placed back against the die-cut cylinder 903 and the machine is put back into operation.

The punching cylinder changing process can preferably take place fully automatically. The punching unit 900 is preferably operatively connected to a machine controller. The cylinder change can be stored in this and then run fully automatically.

In the embodiment with a carrier 972 and two transport elements 960; 956, both cylinders can only be moved together in the predominantly vertical guide 958. Then it may be that the cylinders 901; 903 are guided to intermediate positions in order to control the movement of the punching cylinders 901; 903 to the positions previously described in detail. For example, in the embodiment with the first punching cylinder 901 in the waiting position 986, the other punching cylinder 903 must already be taken out of the maintenance position 987. During the transfer from the predominantly horizontal transport element 965 to the upper of the vertical transport elements 960, for example, the new punching cylinder 903 is already arranged slightly below the extended position 985 on the lower transport element 956. Depending on which of the two cylinders 901; 903 on which transport element rests, the other punching cylinder is carried along vertically.

The accelerated maintenance and/or set-up takes place according to the following procedure. The printing fluid is applied or printed with some of the application units 600, with the rest of the application units 600 being in a switched-off state. In the parked state, the forme cylinders can be serviced or set up, in particular while the processing machine is running. When setting up, at least the order forms are preferably exchanged. However, other processes can also take place during set-up, such as an anilox roller exchange.

The other punching cylinder 903 can preferably also be prepared at the same time, while the at least one punching cylinder 901 is in the punching position 981 and is processing the substrate 02. For this purpose, the further punching cylinder 903 is arranged in the maintenance position of the device for changing 950 . In this position, the other punching cylinder 903 can be conveniently set up or serviced.

When the machining job is finished, the machine is prepared for a new machining job. For this purpose, the further punching cylinder 903 is exchanged with the punching cylinder 901 by means of the changing device 950 . In addition, the shut down and prepared application units 600 are transferred from the shut down state to the shut down state. Both processes preferably run automatically according to a scheme stored in a controller. The punching cylinders 901; 903 are changed according to the procedure described above. The application units 600 also have actuators for switching the application units 600 on and off. Accordingly, the order units 600 can also be transferred from the parked to the hired position.

In the processing machine 01, the sheet 02 must be transported to the processing points 909. For this purpose, the processing machine 01 has a plurality of transport units 700 with transport devices 710. Punching unit 900 also has at least one transport system 710 for feeding sheets 02 to processing point 909. The punching unit 900 preferably has a plurality of transport devices 710. Transport system 710 is preferably designed for overhead sheet transport and is therefore located above a transport path for sheet 02. In another embodiment, transport system 710 can also be arranged below the transport path for sheet 02. For the precise feeding of the sheet 02 to the processing point 909, the transport device 710 projects to just before the processing point 909. When changing the die-cutting cylinder with the device for changing 950, the transport device 710 is in the way. When the punching cylinder 901 is removed horizontally, the transport device 710 is preferably in the way. The punching unit 900 therefore preferably has an adjustment device. Alternatively or additionally, the transport device 710 can be adjusted manually, for example by an operator. In the case of a die-cutting cylinder change, only the part or the transport device 710 that is in the way when the die-cutting cylinder is changed is preferably adjusted. For this purpose, the punching unit 900 preferably has a transport device 710 in the area of the changing device 950 . Then only this part of the transport device 710 is adjusted. In operation of the processing machine 01 is the Transport device 710 arranged in a working position. To change cylinders 901; 903, the transport device 710 can be transferred to a maintenance position. The maintenance position is preferably a position outside the guide path of the device for changing 950 the punching cylinder 901; 903 lies. In a first embodiment, this maintenance position can be next to the working position of the transport device 710 . More preferably, however, the maintenance position is above the working position or above a transport level 993. More preferably, the transport device 710 is arranged at a distance from the transport level 993 in the maintenance position. The transport device 710 is preferably adjusted upwards by at least one cylinder diameter of a punching cylinder 901. Transport level 993 is preferably the level in which a sheet 02 is transported. The embodiment with the maintenance position arranged above is particularly advantageous because the transport device can be lifted in a particularly simple manner. In particular, the transport device 710 is arranged at least temporarily in this maintenance position during a cylinder change. The movement of the adjusting device is preferably synchronized with the movement of the changing device 950 . The transport device 710 is dependent on the position of the punching cylinder 901; 903 adjustable. The movement can, for example, be synchronized electrically, for example by means of an electrical guide axis and a controller, and/or synchronized mechanically via contact elements. The device for changing 950 preferably has contact elements for contacting the adjustment device. In the course of movement of the die-cutting cylinder change, these contact elements and/or contact surfaces are touched and the transport device 710 is set and/or moved out of the way at the appropriate times. It can thus be prevented that the transport device 710 hinders the simple movement of changing the punching cylinder.

In a further preferred embodiment, the transport device 710 is arranged in the maintenance position only pivoted upwards away from the working position, in particular pivoted to the plane 993 . Preferably, the transport device 710 only has to be out of the way for the die-cutting cylinder change.

In a preferred embodiment, the transport device 710 is in the maintenance position above the waiting position of the punching cylinder 901; 903 arranged. This ensures that there is enough space for changing the cylinder.

Furthermore, a transport means 904 arranged after the punching unit 900 can also be adjusted in such a way that an operator can easily reach the punching cylinder and/or the counter-punching cylinder. The means of transport 904 is preferably pivotable for this purpose.

The adjustment device preferably has a drive 961 for adjusting the at least one transport device 710. This drive 961 is preferably a shared drive 961 with the changing device 950. This drive 961 preferably drives at least the transport element 956; 960 and/or the carrier 972 of the device for changing 950 in the vertical guide 958.

The drive 961 is preferably designed as a spindle drive. When the drive 961 is actuated, the transport element 956; 960 and/or the carrier 970 moves up or down in the vertical direction V.

The adjusting device preferably has a frame 991 and/or a housing 991. This is attached to the ends of the transport devices 710 in the axial direction A and is preferably arranged in the guide rail 957 of the guide 958 . The at least one transport device 710 is preferably fixed to the frame 991 and moves together with it. The adjustment device preferably includes a stop on which the frame 991 and/or the transport device 710 rest in the working position. The movement counter to the vertical direction V is preferably restricted by the stop. Furthermore, a horizontal movement of the transport device 710 is restricted by the guide 958 . The transport device 710 preferably has only one degree of freedom in, preferably along, the vertical direction V. Preferably only the movement from the working position in the vertical direction V is possible. The adjusting device preferably has a contact element with a contact surface 992 for contacting the changing device 950 . If the transport element 956; 960 or the carrier 970 is raised in the vertical direction V, this and/or this comes into contact with the contact surface 992 and raises the transport device 710 with it. The transport device 710 is thereby preferably transferred at least temporarily into the maintenance position.

Alternatively, the transport device 710 can also carry out the desired movement using an electronic guide axis. The adjusting device then preferably has a further drive.

The transport device 710 is adjusted according to the method described below. When changing the die-cutting cylinder, the transport device 710 is adjusted by means of the adjustment device from the working position, preferably into the maintenance position, preferably by means of the drive 961. The drive 961 is preferably the common drive 961 of the device for changing 950. The adjustment of the transport device 710 is synchronized with the device for changing 950 or the changing of the punching cylinder. The transport device 710 is preferably adjusted and/or guided on a guide, preferably the linear guide 957.

The transport device 710 is preferably raised by means of the adjustment device in the vertical direction V, against the weight of the transport device 710. For this purpose, the transport device 710 via a contact surface by means of the transport element 956; 960 and/or the carrier 972, preferably from below, and thus adjusted.
