  • a lifting device is provided for moving the cutting roller and counter roller apart.
  • the invention is based on the object of providing a rotary cutting device of the type mentioned at the outset, which has a high level of operational reliability.
  • this object is achieved according to the invention in that the second roller is supported on a wedge device in a support mode, that the wedge device has at least one displaceable wedge element, with a displacement position of the at least one displaceable wedge element having a distance between the second roller and the first roller, and that the at least one displaceable wedge element is assigned a drive device for a displacement movement of the at least one displaceable wedge element in a second displacement axis, wherein the drive device is designed such that when the second roller is lifted off the first roller and a support is removed the second roller on the wedge device, the at least one movable wedge element is automatically displaced in such a way that the second roller is again supported the wedge device is made, in which then the second roll is spaced from the first roll.
  • a material web is guided through between the first roller and the second roller, with the first roller and the second roller in particular rotating at the same peripheral speed.
  • a corresponding cutting force is set via the cutting pressure device.
  • the second roller is pressed against the first roller with the required force.
  • the corresponding introduction of force takes place in particular via a roller bearing.
  • the distance between the second roller and the first roller is fixed in a machining operation for a workpiece (such as a cutting operation), and in particular the second roller bears on the first roller.
  • the web of material contains "disturbances". Such disturbances can be foreign bodies, such as screws, tools, etc., which have got onto the material web.
  • the web may also have deformed products, doubled products, etc., or the web may be misaligned.
  • the material web can have a greater thickness than the normal thickness in some areas. This in turn can lead to the second roller being lifted off when the second roller is displaceable, in which case a rebound of the second roller onto the first roller can generally result due to the introduction of force via the cutting pressure device.
  • Such a rebound can damage the tool roller with damage to a cutting edge and/or the counter-roller, for example with indentations.
  • a roller impact protection is provided.
  • the second roller is also supported via the wedge device, in particular in addition to being directly supported on the first roller.
  • the second roller is additionally supported on the machine frame via the wedge device. If the first roll is fixed against displacement with respect to the machine frame, then there is an additional indirect support of the second roll via the wedge device on the first roll.
  • the drive device provides for a displacement of the at least one displaceable wedge element in the second displacement axis in order to restore support, in which case the support but an impact of the second roll the first roll prevents since the distance between the second roller and the first roller can be increased by moving the at least one wedge element.
  • the wedge device can be integrated into the rotary cutting device and in particular into the machine frame with a relatively small space requirement.
  • the drive device for the displacement movement of the at least one displaceable wedge element can be designed in a structurally simple manner.
  • the drive device can be designed as a pneumatic or hydraulic cylinder or as a motor (electric motor).
  • the displacement movement can be carried out automatically by means of a prestressed drive device without control or regulation effort.
  • the first roller is supported on the second roller via at least one support ring which is arranged on the first roller and/or the second roller.
  • the at least one support ring makes it possible to prevent contact or “excessive contact” between a cutting edge of the tool roller and the mating roller in a machining operation. A precise cut can be made and an optimized cutting force can be set.
  • a first support ring and a second support ring are arranged on a tool roll, with a cutting edge being positioned between the first support ring and the second support ring in relation to a direction parallel to an axis of rotation of the tool roll.
  • the drive device is designed in such a way that a movement of the at least one displaceable wedge element is driven in a direction in which a distance between the second roller and the first roller increases when the second roller is supported on the wedge device is. It can thereby achieve a roll impact protection. Appropriate tracking of the displaceable wedge element by means of the drive device prevents the second roller from impacting on the first roller by restoring it to the wedge device.
  • the drive device is designed in such a way that it exerts a prestress on the at least one displaceable wedge element.
  • a counterforce exerted via the cutting pressure device prevents displacement of the at least one displaceable wedge element during machining operation. If, after a disturbance has occurred, the second roller lifts off the first roller and this counterforce is reduced as a result, the prestressing of the drive device causes the at least one displaceable wedge element to be automatically displaced and the second roller is again supported on the wedge device, whereby in this case, however, an increase in the distance between the second roller and the first roller is produced and thus, in turn, roller impact protection is provided, ie the second roller cannot collide with the first roller.
  • a prestress is provided on the at least one displaceable wedge element (in the support mode)
  • the bias is then specified by the drive device.
  • a controlled bias is provided.
  • the preload is adjusted to the prevailing conditions on the rotary cutting device. For example, the position of a wedge element in the support mode may change due to guide play and vibrations in the rotary cutter. through a regulation With the preload, such changes can be taken into account and, in particular, their effect on the corresponding wedge element can be compensated for.
  • a sensor device is provided for this purpose, which detects a movement and/or change in position of the at least one displaceable wedge element and communicates this to an evaluation device.
  • the evaluation device correspondingly controls the drive device in order to set the pretension as a function of a detected movement or position of the corresponding wedge element and thus to regulate the pretension in a control loop.
  • the drive device is designed in such a way that it does not exert any pretension on the at least one displaceable wedge element.
  • no compensation for a displacement or change in position of the at least one displaceable wedge element is necessary in the support mode.
  • Such movements or changes in position can arise, for example, as a result of guide play and/or vibrations in the rotary cutting device. If a preload is provided, such movements or changes in position can affect the preload.
  • the drive device is designed in such a way that it can also fulfill its function without prestressing, then such changes in movement in the support mode do not have a negative effect and they do not have to be compensated for.
  • a sensor device which detects a position of the second roller relative to the machine frame, with the sensor device in particular being designed as a distance measuring sensor device or position sensor device.
  • the sensor device makes it possible in particular to detect a lifting of the second roller and thus to detect an end of the support mode. This in turn can be used to control the drive device in such a way that a corresponding displacement movement of the at least one displaceable wedge element takes place.
  • the sensor device is advantageous when there is no bias is provided between the drive device and the wedge device.
  • the sensor device is connected in a signal-effective manner to an evaluation device and the evaluation device controls the drive device as a function of signals from the sensor device.
  • the evaluation device can use the sensor device to detect a position and in particular a lifting position of the second roller. This can then be used for a corresponding activation of the drive device and movement of the at least one displaceable wedge element.
  • the evaluation device controls the drive device in such a way that when the sensor device detects a threshold value, which corresponds to the second roller being lifted off the first roller and the second roller no longer being supported on the wedge device, the at least one movable wedge element is shifted and in particular is automatically shifted in such a way that the second roller is again supported on the wedge device, the second roller then being spaced apart from the first roller.
  • Roller impact protection can thus be implemented automatically via the detection results of the sensor device. This roller impact protection is automated. It can be achieved independently of movements or changes in position of the at least one displaceable wedge element in the support mode (caused, for example, by guide play and/or vibrations).
  • the drive device is designed in such a way that when the second roller is lifted off the first roller and the second roller is no longer supported on the wedge device, the at least one displaceable wedge element is automatically displaced in such a way that the second roller is again supported on the wedge device, in which then the second roll is spaced from the first roll.
  • this roller impact protection can be achieved without control effort or regulation effort.
  • the support mode in which the second roller is supported on the wedge device and thus in particular on the machine frame, is present in normal machining operation and is present when, after the second roller has been lifted off the first roller, the at least one displaceable wedge element is moved again Support of the second roll was moved to the wedge device.
  • the second roll In the machining operation, in particular the second roll is supported on the first roll by at least one support ring, and there is also support by the wedge device.
  • the support mode does not exist for a short time if a corresponding disruptive body is contained in the material web, which causes the second roller to lift off the first roller. During this lifting process, the second roll is not supported on the wedge device.
  • the support mode is only present again when the at least one movable wedge element has been adjusted in such a way that there is renewed support. There is then no longer any (additional) support via a support ring.
  • the wedge device comprises at least one partial device with a first wedge element and a second wedge element, with the first wedge element being supported on the second wedge element in the support mode, and with the first wedge element and/or the second wedge element being displaceable and coupled to the drive device is.
  • a permanent support of the second roller on the wedge device can thus be achieved in the support mode.
  • tracking of the at least one displaceable wedge element can be achieved in a simple manner, in order to reach the support mode again if a support mode is briefly canceled.
  • first wedge element is assigned to the first roller and the second wedge element is assigned to the second roller.
  • the first wedge element is connected to the first roller so as to be non-displaceable with respect to the first displacement axis. If the first roller is non-displaceable in relation to the machine frame in the first displacement axis, then the first wedge element is also arranged non-displaceably in relation to the first displacement axis on the machine frame. It is then structurally advantageous if the first wedge element is displaceable, since the displaceability in the first displacement axis can be realized in a non-displaceable manner with respect to the machine frame. In particular, the first wedge element can then be guided on a displacement guide, which is non-displaceable with respect to the machine frame.
  • the second wedge element is displaceable with the second roller in the first displacement axis (relative to the machine frame). In this way, in particular in an effective and structurally simple manner, a roll impact protection can be achieved after the second roll is lifted relative to the first roll.
  • the first wedge element is arranged on a first bearing housing of the first roll, via which the first roll is seated on the machine frame.
  • the first roller is rotatably mounted about an axis of rotation via the bearing housing.

  • the second roller is rotatably mounted via the bearing housing.
  • the second roller can also be displaced in the first displacement axis relative to the machine frame via the bearing housing.
  • both the first roller and the second roller can be displaceable relative to the machine frame (in the first displacement axis).
  • the first roller is positioned on the machine frame so as to be non-displaceable with respect to the first displacement axis.
  • the second roller which is slidable in the first displacement axis relative to the first roller on the machine frame, is then seated above the first roller in relation to the direction of gravity.
  • first displacement axis is oriented transversely and in particular perpendicular to the second displacement axis. This results in effective roller impact protection with a structurally simple design of the roller impact protection.
  • the corresponding wedge device can be integrated into the rotary cutting device with little space requirement.
  • the first displacement axis is an axis that is parallel to the direction of gravity.
  • the second displacement axis is then in particular a horizontal axis.
  • first axis of displacement and/or the second axis of displacement are oriented transversely and in particular perpendicularly to an axis of rotation of the first roller. This results in an effective cutting operation with a structurally simple design protection against roller impact.
  • the wedge device comprises a first sub-device and a second sub-device, the first sub-device and the second sub-device being spaced apart from one another in a direction parallel to an axis of rotation of the first roll, and with the support mode supporting the second roll on both the first sub-device and is supported on the second sub-device. This results in a symmetrical support of the second roll with respect to the machine frame.
  • first sub-device and the second sub-device are of the same design, resulting in effective support and also effective roller impact protection.
  • the orientation of the axes of rotation of the first Roll and the second roll not changed to each other and in particular they remain oriented parallel.
  • the drive device has a first drive for the first sub-device and a second drive for the second sub-device, with the first drive and the second drive in particular being synchronized. It is possible to achieve effective roll impact protection. An orientation of the axes of rotation of the first roller and the second roller is retained and in particular the parallelism of the axes of rotation is retained.
  • the drive device is designed in such a way that it constantly exerts a force on the at least one displaceable wedge element. It is then provided in particular that in a machining operation, taking into account the force exerted via the cutting pressure device, the force exerted by the drive device is not sufficient to displace the at least one displacement element. Only when the force is reduced, which occurs when the second roller is lifted off the first roller, does the constant application of force lead to a displacement of the at least one movable wedge element. A type of prestressing on the wedge device can thus be achieved in a simple manner via the drive device. In the event of a fault, the at least one movable wedge element can be displaced in a simple manner without, for example, a complex control circuit being necessary. It is also possible for a controlled force (a controlled pretension) to be constantly exerted on the at least one displaceable wedge element. Furthermore, it is possible that there is no permanent pretension on the displaceable wedge element.
  • the drive device is or includes, for example, a mechanical drive (in particular with a spring device) or pneumatic drive (with one or more pneumatic cylinders) or hydraulic drive (with one or more hydraulic cylinders) or magnetic drive or inductive drive or electromagnetic drive or a motor drive.
  • the drive device can be designed to be relatively compact and integrated into the rotary cutting device in a space-saving manner.
  • the tool roller is a cutting roller or an embossing roller or a knife roller or a compression roller or a crushing roller.
  • the tool roller causes workpiece processing, in particular in a defined area of the workpiece.
  • a cutting roller the shape of a cutting edge specifies the workpiece machining area.
  • the first roller and/or the second roller is supported by at least one other roller. Excessive deflection of the first roller or second roller can be prevented as a result.
  • the first roller can be supported directly on the second roller (in particular via support rings), particularly during the cutting operation.
  • there is in particular indirect support via the wedge device This provides a starting position to achieve effective roll crash protection.
  • the drive device moves the at least one displaceable wedge element (preferably automatically) in such a way that due to a then restored support of the second roller on the wedge device, the second roller cannot collide against the first roller. Proceeding from a support mode, there is briefly no longer any support on the wedge device when the second roller is lifted off the first roller. By pushing the at least one displaceable wedge element further, the support is restored (whereby in particular there is no longer any support ring support). In the state of this restored support, however, the at least one sliding wedge element is displaced with respect to its initial position in the cutting operation and thereby the distance between the second roller and the first roller is increased compared to the machining operation.
  • the rotary cutting device then usually has to be switched off, and this can be done automatically, in particular.
  • a machining operation is only possible again when the wedge device with the at least one movable wedge element is brought into its starting position for the machining operation.
  • a sensor device which determines a displacement position of the at least one displaceable wedge element and in particular determines it relative to the machine frame. It can then be recognized via the sensor device that the second roller has been lifted off the first roller. This manifests itself in a changed displacement position of the at least one displaceable wedge element. This means a disruption in normal operation and the rotary cutting device is then switched off, in particular on the basis of the corresponding sensor signals.
  • a display device and/or an evaluation device is provided, which is coupled to the sensor device in a signal-effective manner. If it is recognized that a new displacement position of the at least one displaceable wedge element is present, which must be caused by a fault, then the rotary cutting device can be switched off via the evaluation device in order to prevent further possible damage. Furthermore, faults in the material web can then also be detected with regard to products and corresponding faults can be eliminated. A corresponding fault can be displayed via the display device.
