Description

Die Erfindung betrifft eine Rotationsschneidmaschine für die druckverarbeitende Industrie, die ein Obermesser und ein Untermesser aufweist, welche einen einstellbaren Schnittspalt bilden und die jeweils mit einer Messerwelle rotierbar an einem Maschinengestell gelagert sind, mit einer Steuervorrichtung, mit einem Messerantrieb und einer Verstellvorrichtung, mit der wenigstens eines der genannten Messer zum Einstellen des Schnittspaltes in Längsrichtung einer Messerwelle verstellbar ist, wobei eine Nullposition und von dieser aus eine Schnittposition einstellbar sind.The invention relates to a rotary cutting machine for the printing industry, which has an upper blade and a lower blade, which form an adjustable kerf and which are each rotatably mounted with a knife shaft on a machine frame, with a control device, with a blade drive and an adjusting device, with at least one of said knives for adjusting the kerf is adjustable in the longitudinal direction of a blade shaft, wherein a zero position and from this a cutting position are adjustable.

Solche Rotationsschneidmaschinen sind seit langem bekannt. Eine solche ist beispielsweise durch die EP 0 3405621.8 (Anmeldetag 28. August 2003) des Anmelders bekannt geworden.Such rotary cutting machines have been known for a long time. Such has become known, for example, from EP 0 3405621.8 (filing date August 28, 2003) by the applicant.

Um bei Rotationsschneidmaschinen ein optimales Schneidergebnis zu erreichen, muss der Schnittspalt zwischen Obermesser und Untermesser in einem Bereich von beispielsweise 0.03 mm bis 0.035 mm eingestellt werden. Das Verstellen erfolgt über eine Stellspindel mit Nonius. Verstellt wird das Obermesser oder das Untermesser. Das korrekte Einstellen des Schnittspaltes setzt ein sehr genaues und sorgfältiges Arbeiten voraus. Wird nicht mit der nötigen Sorgfalt gearbeitet, so ist der Schnittspalt entweder zu gross oder zu klein. Bei einem zu grossen Schnittspalt ist die Schnittqualität ungenügend und bei einem zu kleinen Schnittspalt können die teuren Klingen des Obermessers brechen.In order to achieve optimum cutting results in rotary cutting machines, the cutting gap between upper blade and lower blade must be set in a range of, for example, 0.03 mm to 0.035 mm. The adjustment is done via a Adjusting spindle with vernier. The upper knife or the lower knife is adjusted. The correct setting of the kerf requires a very precise and careful work. If you do not work with the necessary care, the kerf is either too big or too small. If the cutting gap is too large, the cutting quality is insufficient and if the cutting gap is too small, the expensive blades of the upper knife can break.

Das Einstellen des Schnittspaltes erfolgt in der Regel von Hand, wobei das verstellbare Messer zuerst von einer Ausgangsposition in die Nullposition gefahren und von dieser in Gegenrichtung in die Schnittposition gefahren wird. Um eine solche Einstellung korrekt durchführen zu können, ist ein gewisses mechanisches Verständnis nötig. In der Regel muss deshalb ein Mechaniker beigezogen werden.The adjustment of the cutting gap is usually done by hand, the adjustable knife is first moved from a starting position to the zero position and driven by this in the opposite direction in the cutting position. In order to perform such a setting correctly, a certain mechanical understanding is necessary. As a rule, therefore, a mechanic must be consulted.

Aus der EP 1 177 833 ist eine Rotationsschneidmaschine bekannt geworden, bei welcher die Schneide des Obermessers und die Schneide des Untermessers elektrisch gegeneinander isoliert sind. Berühren sich beim Schneidvorgang die beiden Messer, so wird ein Stromkreis geschlossen und ein optisches oder akustisches Signal abgegeben. Die Ursache für ein solches Berühren der Schneiden ist in der Regel eine starke Wärmeausdehnung. Mit dem genannten Signal soll es möglich sein, die Maschine beim Berühren der Schneiden abzustellen und damit einen Schaden an den Schneiden zu vermeiden. Ein Signal wird ungewollt auch dann abgegeben, wenn der Stromkreis beispielsweise durch Öl im Schnittspalt geschlossen wird. Das Einstellen des Schnittspaltes ist aber auch bei dieser Rotationsschneidmaschine mit den oben genannten Nachteilen versehen.From EP 1 177 833 a rotary cutting machine has become known in which the cutting edge of the upper blade and the blade of the lower blade are electrically insulated from each other. If the two blades touch each other during the cutting process, a circuit is closed and an optical or acoustic signal is emitted. The cause of such touching of the blades is usually a strong thermal expansion. With the above signal, it should be possible to turn off the machine when touching the cutting edges and thus to avoid damage to the cutting. A signal is unintentionally delivered even if the circuit is closed, for example, by oil in the kerf. The setting of the cutting gap but also provided with this rotary cutting machine with the disadvantages mentioned above.

Der Erfindung liegt die Aufgabe zugrunde, eine Rotationsschneidmaschine der genannten Art zu schaffen, bei welcher der Schnittspalt wesentlich einfacher und sicherer eingestellt werden kann.The invention has for its object to provide a rotary cutting machine of the type mentioned, in which the kerf can be set much easier and safer.

Die Aufgabe wird dadurch gelöst, dass die Nullposition des verstellbaren Messers durch einen Signalgeber selbsttätig ermittelbar ist, und die Verstellvorrichtung einen Verstellantrieb aufweist, mit dem das verstellbare Messer durch einen Signalgeber gesteuert von der Nullposition selbsttätig in die Schnittposition verfahrbar ist.The object is achieved in that the zero position of the adjustable blade is automatically determined by a signal generator, and the adjusting device has an adjustment, with which the adjustable blade is controlled by a signal generator from the zero position automatically moved into the cutting position.

Bei der erfindungsgemässen Rotationsschneidmaschine weist die Verstellvorrichtung einen Verstellantrieb auf. Bei der erfindungsgemässen Rotationsschneidmaschine kann somit die Nullposition selbsttätig angefahren werden und ausgehend von dieser wird der Schnittspalt eingestellt. Sobald die Nullposition erreicht ist, wird das verstellbare Messer angehalten und mit dem Verstellantrieb in der Gegenrichtung in die Schnittposition bewegt. Die Einstellung des Schnittspaltes kann damit im Wesentlichen selbsttätig erfolgen. Da die Einstellung selbsttätig gesteuert ist, können Fehlmanipulationen ausgeschlossen werden.In the case of the rotary cutting machine according to the invention, the adjusting device has an adjusting drive. In the case of the rotary cutting machine according to the invention, the zero position can thus be approached automatically, and starting from this, the cutting gap is set. Once the zero position is reached, the adjustable blade is stopped and moved with the adjustment in the opposite direction in the cutting position. The adjustment of the kerf can thus essentially be done automatically. Since the setting is automatically controlled, false manipulations can be ruled out.

Mit dem Verstellantrieb ist gemäss einer Weiterbildung der Erfindung das verstellbare Messer von einer einstellbaren Ausgangsposition in die Nullposition verfahrbar. In der Ausgangsposition beträgt die Schnittspaltbreite beispielsweise 1.0 mm. Ein solcher Schnittspalt ist ohne das Risiko eines Klingenbruches einfach und sicher einstellbar. Beim Anfahren der Nullposition wird gemäss einer Weiterbildung der Erfindung das andere Messer mit dem Messerantrieb gedreht. Ist die Nullposition erreicht, so wird das verstellbare Messer durch Reibung am anderen Messer mitgedreht.With the adjusting drive, the adjustable blade can be moved from an adjustable starting position to the zero position according to an embodiment of the invention. In the initial position, the kerf width is 1.0 mm, for example. Such a kerf is easily and safely adjustable without the risk of blade breakage. When starting up the zero position is rotated according to an embodiment of the invention, the other knife with the knife drive. When the zero position is reached, the adjustable blade is rotated by friction on the other knife.

Nach einer Weiterbildung der Erfindung ist der Signalgeber so ausgebildet, dass er dieses Mitdrehen des verstellbaren Messers detektiert. Eine solche Drehbewegung kann besonders zuverlässig und sicher mit einem Drehgeber ermittelt werden. Der Drehgeber gibt beim Erreichen der Nullposition ein Signal an den Verstellantrieb, der sofort stoppt und anschliessend das verstellbare Messer zur Einstellung des Schnittspaltes in der Gegenrichtung bewegt. Mit einem Drehgeber, der die Nullposition besonders zuverlässig und präzise feststellt, können Beschädigungen, insbesondere der Klingen, vermieden werden.According to a development of the invention, the signal generator is designed so that it detects this turning of the adjustable blade. Such a rotational movement can be determined particularly reliably and safely with a rotary encoder. When the zero position is reached, the rotary encoder sends a signal to the adjusting drive, which stops immediately and then moves the adjustable blade to set the cutting gap in the opposite direction. With a rotary encoder that detects the zero position particularly reliable and precise, damage, especially the blades, can be avoided.

Nach einer Weiterbildung der Erfindung ist vorgesehen, dass die Steuervorrichtung die Nullposition speichert und dass ausgehend von diesem gespeicherten Wert das verstellbare Messer selbsttätig in die Schnittposition verfahrbar ist.According to a development of the invention it is provided that the control device stores the zero position and that starting from this stored value, the adjustable blade is automatically moved into the cutting position.

Vorzugsweise ist ein weiterer Drehgeber vorgesehen, mit welchem der Schnittspalt beim Verfahren in die Schnittposition bestimmt wird.Preferably, a further rotary encoder is provided, with which the cutting gap is determined during the process in the cutting position.

Das Verstellen des verstellbaren Messers erfolgt vorzugsweise mit einer Verstellspindel, die mit einer Büchse oder einem Schlitten in Eingriff ist. Die Messerwelle des verstellbaren Messers ist an dieser Büchse bzw. der Verstellspindel gelagert. Mit der Verstellspindel sind sehr präzise Bewegungen möglich.The adjustment of the adjustable knife is preferably carried out with an adjusting spindle, which is in engagement with a bush or a carriage. The knife shaft of the adjustable knife is mounted on this bushing or the adjusting spindle. With the adjusting spindle very precise movements are possible.

Bei der erfindungsgemässen Rotationsschneidmaschine kann eine bestimmte Schnittspaltbreite vorgegeben werden, die dann selbsttätig eingestellt wird. Da der Vorgang im Wesentlichen selbsttätig abläuft, ist es wesentlich einfacher, die Schnittspaltbreite zu ändern. Damit bietet sich die Möglichkeit, die Schnittspaltbreite an das entsprechende Produkt anzupassen bzw. die Schnittspaltbreite zu variieren.In the rotary cutting machine according to the invention, a specific cutting gap width can be predetermined, which is then set automatically. Since the process essentially proceeds automatically, it is much easier to change the kerf width. This makes it possible to adapt the kerf width to the corresponding product or to vary the kerf width.

Vorzugsweise wird das Untermesser verstellt. Grundsätzlich ist aber auch eine Ausführung denkbar, bei welcher das Obermesser verstellt wird.Preferably, the lower blade is adjusted. In principle, however, a design is conceivable in which the upper blade is adjusted.

Grundsätzlich ist es auch möglich, eine vorbestimmte Schnittspaltbreite in der Steuerung zu speichern. Diese Schnittspaltbreite wird dann selbsttätig eingestellt, nachdem der Befehl zur Schnittspalteinstellung eingegeben wurde. Es ist auch möglich, mehrere solche Schnittspaltbreiten vorzugeben.In principle, it is also possible to store a predetermined kerf width in the controller. This kerf width is then set automatically after the cut gap setting command is entered. It is also possible to specify several such kerf widths.

Weitere vorteilhafte Merkmale ergeben sich aus den abhängigen Patentansprüchen, der nachfolgenden Beschreibung sowie der Zeichnung.Further advantageous features emerge from the dependent claims, the following description and the drawings.

Die in Figur 1 gezeigte Rotationsschneidmaschine 1 besitzt ein Maschinengestell 2, an dem ein Obermesser 5 und ein Untermesser 7 gelagert sind. Das Obermesser 5 ist von einem Motor 3 angetrieben, der mit einem hier nicht sichtbaren unter einer Abdeckung 4 angeordneten Antriebsorgan angetrieben ist. Das Antriebsorgan wirkt auf eine hier nicht gezeigte zweite Welle des Obermessers 5. Das Obermesser 5 besitzt an seinem Umfang eine Mehrzahl von Klingen, die aus einem geeigneten Hartmetall hergestellt und aufgeklemmt sind. Das Untermesser 7 bildet das Gegenmesser und besitzt einen Ring 8 aus Hartmetall, der mit den Klingen 6 zusammenarbeitet. Das Obermesser 5 und das Untermesser 7 sind gemäss Figur 2 um parallele Achsen A1 und A2 rotierbar.The rotary cutting machine 1 shown in FIG. 1 has a machine frame 2 on which an upper blade 5 and a lower blade 7 are mounted. The upper blade 5 is driven by a motor 3, which is driven by a not visible here under a cover 4 arranged drive member. The drive member acts on a second shaft, not shown here, of the upper blade 5. The upper blade 5 has at its periphery a plurality of blades, which are made of a suitable hard metal and clamped. The lower blade 7 forms the counter blade and has a ring 8 made of hard metal, which cooperates with the blades 6. The upper blade 5 and the lower blade 7 are rotatable about parallel axes A1 and A2 according to FIG.

Wie die Figur 2 zeigt, weist das Untermesser 7 eine Messerwelle 11 auf, die mit zwei Lagerelementen 17 in einer Büchse 16 drehbar gelagert ist. Die Büchse 16 ist in einer Lagerbohrung 21 des Maschinengestells 2 in Längsrichtung der Messerwelle 11 verschiebbar, jedoch gegen ein Verdrehen gesichert. Zum Verschieben der Büchse 16 ist eine Verstellvorrichtung 10 mit einem Verstellantrieb 12 vorgesehen. Dieser besitzt einen Verstellmotor V, der vorzugsweise ein steuerbarer Elektromotor ist und mit dem ein Zahnrad 13 antreibbar ist, welches mit einem weiteren vorzugsweise grösseren Zahnrad 14 in Eingriff ist. Mit dem Zahnrad 14 ist fest eine Stellspindel 15 verbunden, welche an der Büchse 16 angreift. Je nach Drehrichtung der Spindel 15 wird die Büchse 16 in Figur 2 nach links oder nach rechts bewegt. Entsprechend wird das Untermesser 7 nach links oder nach rechts bewegt. Der Verstellmotor V wird hierbei von einer Steuerung ST gesteuert.As FIG. 2 shows, the lower blade 7 has a blade shaft 11, which is rotatably mounted in a bush 16 with two bearing elements 17. The sleeve 16 is displaceable in a bearing bore 21 of the machine frame 2 in the longitudinal direction of the blade shaft 11, but secured against rotation. To move the sleeve 16, an adjusting device 10 is provided with an adjusting 12. This has an adjusting motor V, which is preferably a controllable electric motor and with which a gear 13 is driven, which is in engagement with a further, preferably larger gear 14. With the gear 14, an adjusting spindle 15 is fixedly connected, which acts on the sleeve 16. Depending on the direction of rotation of the spindle 15, the sleeve 16 in Figure 2 to the left or moved to the right. Accordingly, the lower blade 7 is moved to the left or to the right. The adjusting motor V is controlled by a controller ST here.

Das Obermesser 5 ist von einem weiteren Motor F angetrieben, der auch als Fräsermotor bezeichnet werden kann. Beim Schneidvorgang ist somit das Obermesser 5 angetrieben. Das drehbar gelagerte Untermesser 7 wird hierbei zwangsläufig mitgedreht.The upper blade 5 is driven by a further motor F, which may also be referred to as a milling motor. During the cutting process, the upper blade 5 is thus driven. The rotatably mounted lower blade 7 is inevitably rotated in this case.

Die Drehbewegung der Messerwelle 11 kann mit einem ersten Drehgeber D1 detektiert werden. Beginnt die Messerwelle 11 zu drehen, so wird dies vom ersten Drehgeber D1 festgestellt und er sendet unmittelbar über eine Signalleitung 22 ein entsprechendes Signal an die Steuervorrichtung ST. Ein zweiter Drehgeber D2 ist vorgesehen, um die Bewegung der Spindel 15 in ihrer Längsrichtung zu messen. Dieser zweite Drehgeber D2 ist über eine weitere Signalleitung 23 mit der Steuervorrichtung ST verbunden.The rotational movement of the knife shaft 11 can be detected with a first rotary encoder D1. If the knife shaft 11 begins to rotate, this is detected by the first rotary encoder D1 and it sends a signal directly to the control device ST via a signal line 22. A second rotary encoder D2 is provided to measure the movement of the spindle 15 in its longitudinal direction. This second rotary encoder D2 is connected via a further signal line 23 to the control device ST.

Nachfolgend wird das Verfahren zum Einstellen des Schnittspaltes S näher erläutert.The method for adjusting the cutting gap S will be explained in more detail below.

Der einzustellende Schnittspalt S wird gemäss Figur 2 durch eine Fläche 19 des Obermessers 15 und eine Fläche 20 des Untermessers 7 gebildet. Die Fläche 19 wird durch Flächen der Klingen 6 und durch eine innere Fläche des Hartmetallringes 8 gebildet. Der Schnittspalt S besitzt in der Schnittposition des verstellbaren Untermessers 7 eine Breite von beispielsweise 0.03 bis 0.035 mm. Es sind hier aber auch andere Spaltbreiten denkbar. In der Figur 2 ist dieser Abstand durch die Pfeile 18 angedeutet. Die Spaltbreite ist hier aus zeichnerischen Gründen wesentlich grösser dargestellt als in der Wirklichkeit.The cutting gap S to be set is formed according to FIG. 2 by a surface 19 of the upper blade 15 and a surface 20 of the lower blade 7. The surface 19 is formed by surfaces of the blades 6 and by an inner surface of the hard metal ring 8. The cutting gap S has in the cutting position of the adjustable lower blade 7, for example, a width of 0.03 to 0.035 mm. But there are also other gap widths conceivable here. In FIG. 2, this distance is indicated by the arrows 18. The gap width is here from drawing Reasons presented much larger than in reality.

Zum Einstellen des Schnittspaltes S wird das Untermesser 7 mit dem in Figur 1 gezeigten Drehknopf 9 in eine Position gefahren, indem der Abstand zwischen den Flächen 19 und 20 wesentlich grösser ist als der einzustellende Schnittspalt. Dieser Abstand beträgt beispielsweise 1.0 mm. Grundsätzlich kann dieser Abstand jedoch auch selbsttätig eingestellt werden.To set the cutting gap S, the lower blade 7 is moved with the rotary knob 9 shown in Figure 1 in a position by the distance between the surfaces 19 and 20 is substantially greater than the cutting gap to be set. This distance is for example 1.0 mm. In principle, however, this distance can also be set automatically.

Ist die genannte Ausgangsposition eingestellt, so wird an einer hier nicht gezeigten Taste der Einstellvorgang ausgelöst. Die Steuervorrichtung ST stellt hierauf den Verstellmotor V so ein, dass das Untermesser 7 in Figur 2 nach links fährt. Gleichzeitig wird das Obermesser 5 vom Motor F angetrieben. Der Hartmetallring 8 nähert sich somit in Figur 2 dem Obermesser 5. Sobald nun der Hartmetallring 8 die Fläche 19 berührt, beginnt das Untermesser 7 zu drehen. Der Grund hierzu ist die Reibung des Hartmetallringes 9 am Obermesser 5. Diese Drehbewegung des Untermessers 7 wird vom ersten Drehgeber D1 detektiert und dieser gibt ein Signal über die Signalleitung 22 an die Steuervorrichtung ST ab. Die Steuervorrichtung ST stoppt sofort den Verstellmotor V, so dass das Obermesser 7 in der eingestellten Position stehen bleibt. Diese Position ist in Figur 3 illustriert und bildet die Nullposition, von der aus der Schnittspalt S eingestellt wird.If the named starting position is set, then the setting process is triggered on a button, not shown here. The control device ST then adjusts the adjusting motor V so that the lower blade 7 moves to the left in FIG. At the same time, the upper blade 5 is driven by the engine F. The hard metal ring 8 thus approaches the upper blade 5 in FIG. 2. As soon as the hard metal ring 8 touches the surface 19, the lower blade 7 begins to rotate. The reason for this is the friction of the carbide ring 9 on the upper blade 5. This rotational movement of the lower blade 7 is detected by the first rotary encoder D1 and this outputs a signal via the signal line 22 to the control device ST from. The control device ST immediately stops the adjusting motor V, so that the upper blade 7 stops in the set position. This position is illustrated in Figure 3 and forms the zero position from which the kerf S is adjusted.

Sobald der Verstellmotor V stillsteht, wird seine Drehrichtung durch Steuerung ST umgekehrt.As soon as the adjusting motor V stops, its direction of rotation is reversed by the control ST.

Die Büchse 16 und ihr das Untermesser 7 bewegen sich nun in Figur 2 nach rechts. Zwischen den beiden Flächen 19 und 20 bildet sich somit wieder ein Abstand. Dieser Abstand wird vom zweiten Drehgeber D2 gemessen und über die Signalleitung 23 der Steuerung ST übermittelt. Der zweite Drehgeber D2 misst primär die Drehung der Spindel 15, die jedoch proportional zum Abstand zwischen den Flächen 19 und 20 ist. Um den Schnittspalt S bzw. der vorbestimmte Abstand zwischen den Flächen 19 und 20 einzustellen, wird die Spindel 15 um einen entsprechenden vorbestimmten Betrag gedreht. In der Regel ist dies eine Teilumdrehung der Spindel 15. Ist diese Umdrehung erreicht, so gibt der zweite Drehgeber D2 ein entsprechende Signal über die Signalleitung 23 an die Steuervorrichtung ST ab. Die Steuervorrichtung ST stoppt hier sofort den Verstellmotor V und damit die weitere Bewegung des Untermessers 7. Der Schnittspalt S ist damit eingestellt und die Rotationsschneidmaschine 1 kann wie vorgesehen zum Schneiden, beispielsweise von Broschüren, Zeitschriften und anderen Druckprodukten verwendet werden.The sleeve 16 and her lower blade 7 now move in Figure 2 to the right. Between the two surfaces 19 and 20 thus again forms a distance. This distance is measured by the second rotary encoder D2 and transmitted via the signal line 23 of the controller ST. The second rotary encoder D2 primarily measures the rotation of the spindle 15 which, however, is proportional to the distance between the surfaces 19 and 20. In order to adjust the cutting gap S or the predetermined distance between the surfaces 19 and 20, the spindle 15 is rotated by a corresponding predetermined amount. As a rule, this is a partial rotation of the spindle 15. When this rotation is reached, the second rotary encoder D2 outputs a corresponding signal via the signal line 23 to the control device ST. The control device ST stops here immediately the adjusting motor V and thus the further movement of the lower blade 7. The cutting gap S is set with it and the rotary cutting machine 1 can be used as intended for cutting, for example, brochures, magazines and other printed products.
