Description

The invention relates to a punching unit with a device for changing a punching cylinder according to the preamble of claim 1 and a method for changing a punching cylinder according to claim 25.

When processing corrugated board, a sheet of corrugated board goes through several processing steps. The sheets are printed or varnished, for example, and their mass and/or shape and/or contour can be changed by at least one shaping device. 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. Punching cylinders have punching tools or knives, which process the substrate during operation and also come into contact with the anvil cylinder. The counter-die cylinders have elastic and resistant coatings or die-cut coverings. When changing jobs, cutting dies have to be exchanged. In order to get the rotary die-cutter ready for operation again quickly, changing devices for die-cutting cylinders are used.

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 disc.

Furthermore, the GB 2 406 069 A a similar arrangement of anvil cylinder and two die cylinders which can be swapped in position. 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 placed on both die-cutting cylinders or transferred from one to 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, 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.

The object of the invention is to provide a punching unit with a device for changing a punching cylinder and a method for changing a punching cylinder.

The object is achieved according to the invention by the features of claim 1 or by the features of claim 25.

The advantages that can be achieved with the invention are, in particular, that an improved punching unit was created with a device for changing a punching cylinder. The punching cylinder can be changed in a simple manner by the changing device. This is achieved in particular in that the punching cylinder can be removed from a punching position and/or changing position in a particularly simple manner, predominantly horizontally. A connecting straight line between the posi tion of the cylinder is then preferably less than 30 ° inclined to a horizontal.

In addition, the die-cutting cylinder can be changed fully automatically with the changing device. Especially inline in a sheet processing machine with application units, such as printing or coating units, the sheet processing machine achieves increased efficiency in terms of processing speed and job changes. The application units also have devices for simplified changing of the cylinders of the application units, for example. An inline, fully automatic die changer 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 this can then be moved to the die-cutting position quickly and fully automatically. The design of the changing device ensures a high degree of automation with a high level of safety and avoids additional costs through a simple design and saving on duplicate components.

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 when the punching cylinders are replaced. 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.

The device for changing punching cylinders preferably has two guides for this purpose. This makes it possible to change the cylinder with a particularly simple sequence of movements. In conjunction with the waiting position for moving the cylinders past one another, the complexity of changing cylinders 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 configuration. 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, the cylinder can be temporarily stored in the waiting position and the other cylinder can simply be moved past it.

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 maintenance position is also much more accessible than 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 only two adjustable elements.

Exemplary embodiments of the invention are shown in the drawings and are described in more detail below.

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 machine 01 embodied as a printing press 01 also has at least one other 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-like substrate 02 or sheets 02 made of corrugated cardboard 02, in particular sheet-like printing material 02 made of corrugated cardboard 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. 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.

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 path. 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. Unless otherwise described, the aggregates 100; 300; 600; 700; 900; 1000 of the processing machine 01 preferably characterized in that the through the respective unit 100; 300; 600; 700; 900; 1000 defined section of a transport path provided for transporting sheets 02 is at least essentially flat and more preferably completely flat. A substantially flat section of the transport path provided for transporting sheets 02 is to be understood as meaning a section that has a minimum radius of curvature of at least 2 meters, more preferably at least 5 meters and even more preferably at least 10 meters and even more preferably at least 50 meters. A completely flat section has an infinitely large radius of curvature and thus is also substantially flat and thus also has a minimum radius of curvature that is at least 2 meters. Unless otherwise described, the aggregates 100; 300; 600; 700; 900; 1000 of the processing machine 01 preferably characterized in that the through the respective unit 100; 300; 600; 700; 900; 1000 defined section of the transport path provided for the transport of sheets 02 runs at least essentially horizontally and more preferably exclusively horizontally. This transport path preferably extends in a direction T, in particular transport direction T. An essentially horizontal transport path provided for the transport of sheets 02 means in particular that the transport path provided in the entire area of the respective unit 100; 300; 600; 700; 900; 1000 exclusively has one or more directions that deviate by at most 30°, preferably at most 15° and more preferably at most 5° from at least one horizontal direction. The direction of the transport path, in particular the transport direction T, is in particular the direction in which the sheets 02 are transported at the point at which the direction is measured. The transport path provided for transporting sheets 02 preferably begins at a point where sheets 02 are removed from a feeder stack 104.

Processing machine 01 preferably has at least one substrate feed system 100, which is more preferably embodied as unit 100, in particular substrate feed unit 100, and/or as module 100, in particular substrate feed module 100. Particularly in the case of a sheet processing machine 01, the at least one substrate feed system 100 is preferably embodied as sheet feeder 100 and/or sheet feeder unit 100 and/or sheet feeder module 100.

Processing machine 01 has, for example, at least one unit designed as a conditioning device, in particular a conditioning unit, which is more preferably designed as a module, in particular as a conditioning module. Such a conditioning device is designed, for example, as a preparation device or as an after-treatment device. Processing machine 01 preferably has at least one unit designed as a preparation device, in particular a preparation unit, which is more preferably designed as a module, in particular as a preparation module, and represents a conditioning device. Processing machine 01 preferably has at least one post-processing device. Processing machine 01 preferably has at least one unit 300, preferably one system device 300, which is more preferably embodied as a system unit 300 and/or system module 300. The at least one contact device 300 is alternatively designed as a component of the substrate feed device 100 or another unit.

The processing machine 01 has, for example, at least one unit 600, e.g. B. application unit 600 on. The at least one application unit 600 is preferably arranged and/or constructed depending on the function and/or application method. The at least one application unit 600 preferably serves to apply at least one respective application fluid or coating medium to the entire surface and/or part of the surface of sheets 02. An example of an application unit 600 is a printing unit 600 or printing module 600, which is used in particular to apply printing ink and/or ink to substrate 02, in particular sheets 02. In particular, the at least one application unit 600 is designed to apply application fluid, preferably printing ink and/or ink, to the entire surface and/or part of the surface of sheets 02, for example. In the foregoing and in the following, any priming unit and/or coating unit that may be provided also apply as such an application unit 600 or printing unit 600.

In particular, independently of the function of the application fluid that can be applied therewith, application units 600 can preferably be differentiated with regard to their application methods. An example of an application unit 600 is a form-based application unit 600, which in particular has at least one fixed, physical and preferably exchangeable printing form. Shape-based application units 600 preferably work according to a planographic printing process, in particular an offset planographic printing process and/or a gravure printing process and/or a relief printing process, particularly preferably a flexographic printing process. The corresponding application unit 600 is then, for example, a flexo application unit 600 or flexo printing unit 600, in particular a flexo application module 600 or flexo printing module 600.

Such a flexographic printing unit 600 preferably has at least one supply roller 603, which is more preferably embodied as an anilox roller 603 and/or has a cell structure on its lateral surface, in particular on the lateral surface of its roller barrel 17. The at least one supply roller 603 is preferably equipped with a forme cylinder 602 in contact and/or arranged so that they can be brought into contact. A supply roller drive M3 is preferably connected and/or can be connected to the supply roller 603 via a detachable connection, for example by means of a clutch. This connection is preferably released when the supply roller 603 is to be stored in the storage device 21 . At least one chamber doctor blade 604 is therefore preferably in contact and/or operatively connected to the supply roller 603, which is embodied in particular as an anilox roller 603. The at least one storage device 21 preferably has at least two, more preferably at least three, even more preferably at least four and even more preferably exactly four storage receptacles, each for accommodating a supply roller 603. In this way, at least one supply roller 603 can always be kept ready in the vicinity of its intended place of use if a supply roller 603 that is currently being used is to be replaced. Typically, such replacement occurs, for example, when a subsequent application requires a lesser or greater amount of application fluid per area. The storage device 21 preferably has at least one movable relocating device 23, by means of which the at least two storage receptacles 22 can be moved and arranged in different storage positions. The storage device 21 is therefore suitable for replacing the anilox roller quickly and easily. In particular in connection with a device for changing die-cutting cylinders 950, an accelerated job change can be achieved. Both devices thus make a decisive contribution to accelerated job changes of the processing machine 01.

A preferred first embodiment of flexo application unit 614 is provided for applying application fluid to substrate 02, in particular sheets 02 and/or printing substrate 02, from below, for example to print it. In this preferred first embodiment of the flexographic applicator unit 614, the forme cylinder 602 is preferably arranged below the impression cylinder 608. In an alternative embodiment, sheets 02 are printed from above. The printing unit 600 is then preferably designed in a mirror-inverted order with structural adjustments. Sheets 02 are preferably punched on the opposite side to the printed image. Therefore, bottom printing is the preferred embodiment. The printing assembly 600 preferably also has a forme cylinder 602. The forme cylinder 602 can preferably be moved relative to the supply roller 603 by means of actuators. As a result, a corresponding application point 609 can preferably be adapted to different thicknesses of substrate 02 to be processed. The forme cylinder 603 preferably has a drive M3. During operation, the forme cylinder 602 is supplied with pressure fluid via the supply roller 603 . For this purpose, the supply roller is in contact with a chamber doctor blade 604 . A counter-pressure cylinder 608 is arranged opposite the forme cylinder 602. The application point 609 is located between the forme cylinder 602 and the counter-pressure cylinder 608.

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.

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 of the punching cylinder 901 is opened. The at least one punching cylinder 901 is ready for removal in the changing position 982. The changing 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. 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. 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 and 30 cm. The actuator preferably has a stroke of at most 50 cm, more preferably at most 30 cm.

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 the lock, 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 takes up 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. That is, 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. It can thereby be achieved that a punching cylinder 901 and a further 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 preferred by the

Guide 959 set. 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, for example, the transport elements move under the cylinders for takeover, whereby these can be slightly 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 a=30°, more preferably less than a=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 direct arranged on top of each 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.

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

When the machine 01 is in operation, the punching cylinder 901 and the counter-punching cylinder 902 are arranged in the punching position 981. 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. For this purpose, the further punching cylinder 903 is preferably adjusted predominantly in the vertical direction V, preferably downwards. During the change, the other punching cylinder 903 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 is released for transfer.

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 has been released, the punching 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 attached or fixed again by means of the locking device. 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 one of the vertical transport elements 960, the new punching cylinder 903, for example, 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.
