Description
Die vorliegende Erfindung betrifft ein Verfahren zum Konturstanzen eines Ausgangsstapels aus blättrigem Gut, insbesondere zum Ausstanzen von Etiketten aus einem Ausgangsstapel aus blättrigem Gut. Ferner betrifft die Erfindung eine Stanzvorrichtung zur Durchführung des Verfahrens.The present invention relates to a method for contour punching an initial stack of sheet material, in particular for punching out labels from an initial stack of sheet material. The invention further relates to a punching device for carrying out the method.
Verwendet wird das erfindungsgemäße Verfahren sowie die erfindungsgemäße Vorrichtung insbesondere zum Stanzen eines aus einer Vielzahl übereinanderliegender, mit einem Etikettenaufdruck versehener Blätter gebildeten Ausgangsstapels. Der Ausgangsstapel aus blättrigem Gut besteht insbesondere aus bedrucktem Papier. In Sonderfällen bestehen die einzelnen Etiketten aus Kunststoff, insbesondere aus einer Kunststofffolie.The method according to the invention and the device according to the invention are used in particular for punching an initial stack formed from a large number of sheets lying one above the other and provided with a label print. The initial stack of sheet material consists in particular of printed paper. In special cases, the individual labels are made of plastic, in particular a plastic film.
Bei dem zu stanzenden Ausgangsstapel handelt es sich insbesondere um einen vorgeschnittenen Nutzenstapel, der eine Quaderform aufweist. Insofern dient das Verfahren bzw. die Vorrichtung dazu, dem vorgeschnittenen Nutzenstapel seine finale Kontur zu geben. So werden Etiketten üblicherweise auf großen Druckbögen gedruckt, die zu mehreren 100 bis über 1 000 Bögen übereinandergestapelt werden. Derartige Druckbogenstapel werden längs und quer vorgeschnitten, wobei dadurch eine Vielzahl von vorgeschnittenen Nutzenstapel gebildet werden, die anschließend vereinzelt werden. Zum Herstellen der fertigen Etiketten wird ein eine geschlossene Kontur aufweisendes Konturstanzmesser, auch als Stanzeisen bezeichnet, verwendet. Das Stanzen erfolgt derart, dass der zu stanzende Stapel gegen das Konturstanzmesser gepresst, insofern in das Konturstanzmesser hineingestoßen wird, wobei Stanzabfall entsteht.The initial stack to be punched is in particular a pre-cut stack of panels that has a cuboid shape. In this respect, the method or the device serves to give the pre-cut stack of benefits its final contour. Labels are usually printed on large printed sheets that are stacked on top of each other to form several hundred to over 1,000 sheets. Such stacks of printed sheets are pre-cut lengthwise and crosswise, thereby forming a large number of pre-cut stacks of sheets then be isolated. To produce the finished labels, a contour punching knife with a closed contour, also known as a punching iron, is used. The punching is carried out in such a way that the stack to be punched is pressed against the contour punching knife, so that it is pushed into the contour punching knife, resulting in punching waste.
Die
Bei einem Konturstanzen eines Ausgangsstapels aus blättrigem Gut, insbesondere zur Herstellung von Etiketten, besteht die Problematik, dass das auszustanzende Etikett häufig eine von einem Rechteck abweichende Form aufweist, somit ein vorgeschnittener quaderförmiger Ausgangsstapel, der der Stanzvorrichtung zugeführt wird, rechteckförmige Blätter bzw. Bögen mit relativ großen unbedruckten Bereich aufweist. Um ein gutes Ergebnis des ausgestanzten Etiketts zu erhalten, insbesondere um unbedruckte Ränder am ausgestanzten Etikett zu vermeiden, ist es in der Regel notwendig, das Etikett derart auszustanzen, dass das Konturstanzmesser im Bereich des bedruckten Bereichs das jeweilige Blatt bzw. den Ausgangsstapel durchdringt, damit das ausgestanzte Etikett bis zu seiner Außenkontur bedruckt ist. Dies führt allerdings zu der Problematik, dass der beim Stanzen gebildete Stanzabfall bedruckte Bereiche aufweist. Die Entsorgung und/oder ein Recycling von Abfall, der bedruckt ist, ist mit höheren Kosten bzw. höherem Aufwand verbunden als dies bei einem Abfall ohne bedruckte Bereiche der Fall ist.When contour punching an initial stack of sheet material, in particular for the production of labels, the problem is that the label to be punched out often has a shape that deviates from a rectangle, thus a pre-cut cuboid initial stack that is fed to the punching device contains rectangular sheets or sheets has a relatively large unprinted area. In order to obtain a good result from the punched-out label, in particular to avoid unprinted edges on the punched-out label, it is generally necessary to punch out the label in such a way that the contour punching knife penetrates the respective sheet or the initial stack in the area of the printed area the punched out label is printed up to its outer contour. However, this leads to the problem that the punching waste formed during punching has printed areas. The disposal and/or recycling of waste that is printed involves higher costs or greater effort than is the case with waste without printed areas.
Dementsprechend ist es Aufgabe der vorliegenden Erfindung, ein Verfahren bereitzustellen, bei dem die Menge von bedrucktem Stanzabfall reduziert werden kann. Ferner ist es Aufgabe der Erfindung, eine Vorrichtung zur Durchführung des erfindungsgemäßen Verfahrens zu schaffen.Accordingly, it is an object of the present invention to provide a method in which the amount of printed punching waste can be reduced. A further object of the invention is to create a device for carrying out the method according to the invention.
Diese Aufgaben werden durch ein Verfahren, das die Merkmale des Patentanspruchs 1 aufweist, sowie eine Stanzvorrichtung, die die Merkmale des Patentanspruchs 3 aufweist, gelöst.These tasks are achieved by a method that has the features of
Das erfindungsgemäße Verfahren zum Konturstanzen eines Ausgangsstapels aus blättrigem Gut, insbesondere zum Ausstanzen von Etiketten aus einem Ausgangsstapel aus blättrigem Gut, weist die folgenden Verfahrensschritte auf:
- Bereitstellen eines zu stanzenden Ausgangsstapels aus blättrigem Gut, wobei das jeweilige Blatt einen bedruckten Bereich und einen den bedruckten Bereich, vorzugsweise vollständig, umgebenden unbedruckten Bereich aufweist, wobei der bedruckte Bereich des jeweiligen Blatts eine Außenkontur aufweist,
- Bereitstellen eines ersten Konturstanzmessers, auch als Stanzeisen bezeichnet, wobei eine Stanzkontur des ersten Konturstanzmessers größer ist als die Außenkontur des bedruckten Bereichs,
- Pressen bzw. Hineinstoßen des bereitgestellten Ausgangsstapels in das erste Konturstanzmesser zur Bildung eines vorgestanzten Stapels derart, dass das erste Konturstanzmesser ausschließlich in dem unbedruckten Bereich den Ausgangsstapel durchdringt, sodass bei diesem ersten Stanzvorgang gebildeter erster Stanzabfall frei von bedruckten Bereichen ist,
- Sammeln des ersten Stanzabfalls,
- Bereitstellen eines zweiten Konturstanzmessers, wobei eine Stanzkontur des zweiten Konturstanzmessers kleiner ist als die Außenkontur des bedruckten Bereichs oder der Außenkontur des bedruckten Bereichs entspricht,
- Pressen des vorgestanzten Stapels in das zweite Konturstanzmesser zur Bildung eines Nutzenstapels, insbesondere zur Bildung eines Stapels von ausgestanzten Etiketten, derart, dass das zweite Konturstanzmesser im bedruckten Bereich, insbesondere ausschließlich im bedruckten Bereich, durch den vorgestanzten Stapel schneidet, sodass bei diesem zweiten Stanzvorgang gebildeter zweiter Stanzabfall bedruckte Bereiche aufweist,
- Sammeln des zweiten Stanzabfalls, wobei der zweite Stanzabfall getrennt von dem ersten Stanzabfall gesammelt wird.
- Providing an initial stack of sheet material to be punched, the respective sheet having a printed area and an unprinted area surrounding the printed area, preferably completely, the printed area of the respective sheet having an outer contour,
- Providing a first contour punching knife, also referred to as a punching iron, wherein a punching contour of the first contour punching knife is larger than the outer contour of the printed area,
- Pressing or pushing the initial stack provided into the first contour punching knife to form a pre-punched stack in such a way that the first contour punching knife penetrates the initial stack only in the unprinted area, so that the first punching waste formed in this first punching process is free of printed areas,
- collecting the first punching waste,
- Providing a second contour punching knife, wherein a punching contour of the second contour punching knife is smaller than the outer contour of the printed area or corresponds to the outer contour of the printed area,
- Pressing the pre-punched stack into the second contour punching knife to form a stack of benefits, in particular to form a stack of punched-out labels, such that the second contour punching knife cuts through the pre-punched stack in the printed area, in particular exclusively in the printed area, so that in this second The second punching waste formed by the punching process has printed areas,
- Collecting the second punching waste, the second punching waste being collected separately from the first punching waste.
Durch das Vorsehen von zumindest zwei Stanzvorgängen wird bei dem ersten Stanzvorgang ein großer Anteil des unbedruckten Bereichs von dem bedruckten Bereich getrennt und der dabei entstehende erste Stanzabfall separat gesammelt, wodurch die Menge des bei dem zweiten Stanzvorgang gebildeten zweiten Stanzabfalls sehr viel geringer ist als wenn lediglich ein einziger Stanzvorgang durchgeführt werden würde. Durch das separate Sammeln des ersten Stanzabfalls und des zweiten Stanzabfalls können diese jeweils einer geeigneten Entsorgung bzw. einem geeigneten Recycling zugeführt werden.By providing at least two punching processes, a large proportion of the unprinted area is separated from the printed area in the first punching process and the resulting first punching waste is collected separately, as a result of which the amount of second punching waste formed in the second punching process is much smaller than if only a single punching process would be carried out. By collecting the first punching waste and the second punching waste separately, they can each be sent for suitable disposal or recycling.
Der Ausgangsstapel aus blättrigem Gut, insbesondere das jeweilige Blatt, weist vorzugsweise eine Quaderform auf. Bei dem Ausgangsstapel kann es sich insbesondere um einen vorgeschnittenen Ausgangsstapel handeln, wobei der Ausgangsstapel derart vorgeschnitten ist, dass auf dem jeweiligen Blatt nur ein einziger geschlossener bedruckter Bereich pro Blatt des vorgeschnittenen Ausgangsstapels vorhanden ist, insbesondere ein einziger Etikettenaufdruck pro Blatt des vorgeschnittenen Ausgangsstapels vorhanden ist. Der Etikettenaufdruck bildet dabei den bedruckten Bereich. Es ist durchaus denkbar, dass sich der bedruckte Bereich teilweise bis an den Rand des jeweiligen Bogens erstreckt. Vorzugsweise weist der Etikettenaufdruck größere Abmessungen als das finale Etikett auf.The initial stack of leafy material, in particular the respective sheet, preferably has a cuboid shape. The output stack can in particular be a pre-cut output stack, the output stack being pre-cut in such a way that on the respective sheet there is only a single closed printed area per sheet of the pre-cut output stack, in particular a single label print per sheet of the pre-cut output stack . The label print forms the printed area. It is entirely conceivable that the printed area partially extends to the edge of the respective sheet. The label print preferably has larger dimensions than the final label.
Als besonders vorteilhaft wird es angesehen, wenn das Pressen des vorgestanzten Stapels in das zweite Konturstanzmesser dadurch erfolgt, dass der Ausgangsstapel beim Pressen des Ausgangsstapels in das erste Konturstanzmesser auf den vorgestanzten Stapel einwirkt. Dadurch ist es nicht notwendig, den vorgestanzten Stapel separat zu handhaben. Insbesondere ist vorgesehen, dass zwischen dem ersten Konturstanzmesser und dem zweiten Konturstanzmesser Führungsstrukturen vorhanden sind, wobei diese Führungsstrukturen dazu dienen, die Bewegung des vorgestanzten Stapels bei einem Pressen des vorgestanzten Stapels in Richtung des zweiten Konturstanzmessers zu führen.It is considered particularly advantageous if the pre-punched stack is pressed into the second contour punching knife by the initial stack acting on the pre-punched stack when the initial stack is pressed into the first contour punching knife. This means it is not necessary to handle the pre-punched stack separately. In particular, it is provided that there are guide structures between the first contour punching knife and the second contour punching knife, these guide structures serving to control the movement of the pre-punched stack when pressing the pre-punched stack in the direction of the second contour punching knife.
Die erfindungsgemäße Stanzvorrichtung dient zur Durchführung des erfindungsgemäßen Verfahrens. Zu diesem Zweck weist die Stanzvorrichtung ein erstes Konturstanzmesser mit einer Stanzkontur, ein zweites Konturstanzmesser mit einer Stanzkontur und einen in Richtung des ersten Konturstanzmessers verfahrbaren Stanzstempel zum Pressen eines Ausgangsstapels in das erste Konturstanzmesser auf. Die Abmessungen der Stanzkontur des ersten Konturstanzmessers sind dabei größer als die Abmessungen der Stanzkontur des zweiten Konturstanzmessers. Beim Durchgang des ersten Konturstanzmessers durch den Ausgangsstapel wird ein vorgestanzter Stapel gebildet. Die Vorrichtung weist eine erste Sammeleinrichtung zum Sammeln des beim Durchgang des ersten Konturstanzmessers durch den Ausgangsstapel gebildeten ersten Stanzabfalls auf. Das zweite Konturstanzmesser ist in Verfahrrichtung des Stanzstempels dem ersten Konturstanzmesser nachfolgend angeordnet, sodass der vorgestanzte Stapel beim Verfahren des Stanzstempels in Richtung des ersten Konturstanzmessers in das zweite Konturstanzmesser hineingepresst wird. Die Vorrichtung weist eine zweite Sammeleinrichtung zum Sammeln des beim Durchgang des zweiten Konturstanzmessers durch den vorgestanzten Stapel gebildeten zweiten Stanzabfalls auf. Die erste Sammeleinrichtung und die zweite Sammeleinrichtung sind dabei nicht identisch, sodass der erste Stanzabfall und der zweite Stanzabfall getrennt voneinander gesammelt werden.The punching device according to the invention is used to carry out the method according to the invention. For this purpose, the punching device has a first contour punching knife with a punching contour, a second contour punching knife with a punching contour and a punch that can be moved in the direction of the first contour punching knife for pressing an initial stack into the first contour punching knife. The dimensions of the punching contour of the first contour punching knife are larger than the dimensions of the punching contour of the second contour punching knife. As the first contour punch knife passes through the initial stack, a pre-punched stack is formed. The device has a first collecting device for collecting the first punching waste formed when the first contour punching knife passes through the initial stack. The second contour punching knife is arranged downstream of the first contour punching knife in the direction of travel of the punching stamp, so that the pre-punched stack is pressed into the second contour punching knife when the punching stamp is moved in the direction of the first contour punching knife. The device has a second collecting device for collecting the second punching waste formed when the second contour punching knife passes through the pre-punched stack. The first collecting device and the second collecting device are not identical, so that the first punching waste and the second punching waste are collected separately from each other.
Es ist durchaus denkbar, dass die erste und die zweite Sammeleinrichtung Bestandteile einer gemeinsamen Abfallsammeleinrichtung sind, beispielsweise die Sammeleinrichtungen durch unterschiedliche Fächer der Abfallsammeleinrichtung gebildet sind.It is entirely conceivable that the first and second collection devices are components of a common waste collection device, for example the collection devices are formed by different compartments of the waste collection device.
Es wird als vorteilhaft angesehen, wenn eine geometrische Form der Stanzkontur des ersten Konturstanzmessers durch eine Skalierung in eine geometrische Form der Stanzkontur des zweiten Konturstanzmessers überführbar ist, wobei ein Skalierungsfaktor kleiner ist als 1.It is considered advantageous if a geometric shape of the punching contour of the first contour punching knife can be converted into a geometric shape of the punching contour of the second contour punching knife by scaling, with a scaling factor being less than 1.
Vorzugsweise entsprechen sowohl die geometrische Form der Stanzkontur des ersten Konturstanzmessers als auch die geometrische Form der Stanzkontur des zweiten Konturstanzmessers, zumindest im Wesentlichen, der geometrischen Form der Außenkontur des bedruckten Bereichs.Preferably, both the geometric shape of the punching contour of the first contour punching knife and the geometric shape of the punching contour of the second contour punching knife correspond, at least essentially, to the geometric shape of the outer contour of the printed area.
Als besonders vorteilhaft wird es angesehen, wenn die Konturstanzmesser ineinander verschachtelt angeordnet sind.It is considered particularly advantageous if the contour punching knives are arranged nested one inside the other.
Vorzugsweise sind sowohl das erste Konturstanzmesser als auch das zweite Konturstanzmesser im Wesentlichen hohlkegelförmig ausgebildet. Dadurch kann das zweite Konturstanzmesser innerhalb des ersten Konturstanzmessers angeordnet werden.Preferably, both the first contour punching knife and the second contour punching knife are essentially hollow conical. As a result, the second contour punching knife can be arranged within the first contour punching knife.
Die Stanzvorrichtung weist zumindest ein Ableitelement zum Ableiten des ersten Stanzabfalls in die erste Sammeleinrichtung und/oder zum Ableiten des zweiten Stanzabfalls in die zweite Sammeleinrichtung auf.The punching device has at least one diverting element for diverting the first punching waste into the first collecting device and/or for diverting the second punching waste into the second collecting device.
Bei diesem Ableitelement kann es sich beispielsweise um ein plattenförmiges Element, beispielsweise in Art einer Trennwand, handeln. Es ist durchaus denkbar und bevorzugt, dass sich das Ableitelement zwischen den beiden Konturstanzmessern in Richtung der Sammeleinrichtungen erstreckt.This diverting element can be, for example, a plate-shaped element, for example in the form of a partition. It is entirely conceivable and preferred for the diverting element to extend between the two contour punching knives in the direction of the collecting devices.
Als besonders vorteilhaft wird es angesehen, wenn die jeweilige Sammeleinrichtung unterhalb des jeweiligen Konturstanzmessers angeordnet ist.It is considered particularly advantageous if the respective collecting device is arranged below the respective contour punching knife.
Als besonders vorteilhaft wird es angesehen, wenn es sich bei der ersten Sammeleinrichtung und/oder bei der zweiten Sammeleinrichtung um einen Abfallbehälter, insbesondere einen rollbaren Abfallbehälter, handelt. Vorzugsweise handelt es sich bei dem Abfallbehälter um eine handelsübliche Mülltonne. Insbesondere weist die Vorrichtung separat voneinander handhabbare Abfallbehälter auf.It is considered particularly advantageous if the first collecting device and/or the second collecting device is a waste container, in particular a rollable waste container. The waste container is preferably a commercially available garbage can. In particular, the device has waste containers that can be handled separately from one another.
Es wird als vorteilhaft angesehen, wenn das erste Konturstanzmesser und/oder das zweite Konturstanzmesser verschiebbar und/oder schwenkbar in der Stanzvorrichtung gelagert ist, insbesondere die Konturstanzmesser zueinander verschiebbar und/oder zueinander schwenkbar in der Stanzvorrichtung gelagert sind. Dadurch kann in besonders einfacher Art und Weise das erste Konturstanzmesser und/oder das zweite Konturstanzmesser in seiner Lage geändert werden, insbesondere um eine optimale Ausrichtung des jeweiligen Konturstanzmessers zu dem Ausgangsstapel bzw. den vorgestanzten Stapel und/oder dem Stanzstempel zu erreichen.It is considered advantageous if the first contour punching knife and/or the second contour punching knife is mounted in the punching device in a displaceable and/or pivotable manner, in particular if the contour punching knives are mounted in the punching device in a displaceable and/or pivotable manner relative to one another. As a result, the position of the first contour punching knife and/or the second contour punching knife can be changed in a particularly simple manner, in particular in order to achieve an optimal alignment of the respective contour punching knife to the initial stack or the pre-punched stack and/or the punch.
Als besonders vorteilhaft wird es angesehen, wenn das erste Konturstanzmesser und/oder das zweite Konturstanzmesser in einer gemeinsamen Lagerstruktur gelagert sind, wobei die Lagerstruktur schwenkbar und/oder verschiebbar in der Stanzvorrichtung gelagert ist. Dadurch ist es möglich, das erste Konturstanzmesser und das zweite Konturstanzmesser gemeinsam auszurichten, insbesondere bezüglich des Ausgangsstapels auszurichten. In diesem Zusammenhang ist es durchaus denkbar, dass die Position und Ausrichtung des ersten Konturstanzmessers zu dem zweiten Konturstanzmesser unveränderlich ist.It is considered particularly advantageous if the first contour punching knife and/or the second contour punching knife are mounted in a common bearing structure, the bearing structure being pivotably and/or displaceably mounted in the punching device. This makes it possible to align the first contour punching knife and the second contour punching knife together, in particular to align them with respect to the initial stack. In this context, it is entirely conceivable that the position and orientation of the first contour punching knife relative to the second contour punching knife is unchangeable.
Es ist aber auch durchaus denkbar, dass das erste Konturstanzmesser und/oder das zweite Konturstanzmesser verschiebbar und/oder schwenkbar in der Lagerstruktur gelagert ist.However, it is also entirely conceivable that the first contour punching knife and/or the second contour punching knife is mounted in the bearing structure in a displaceable and/or pivotable manner.
Als besonders vorteilhaft wird es angesehen, wenn die Stanzkontur des ersten Konturstanzmessers und/oder die Stanzkontur des zweiten Konturstanzmessers als geschlossene Kontur ausgebildet sind.It is considered particularly advantageous if the punching contour of the first contour punching knife and/or the punching contour of the second contour punching knife are designed as a closed contour.

Die
Der Ausgangsstapel 1 ist aus mehreren, übereinandergestapelten Bögen gebildet, und derart vorgeschnitten, dass dieser quaderförmig ist und auf dem jeweiligen Bogen ein einziger Etikettenaufdruck 20 aufgedruckt ist. Insofern weist der jeweilige Bogen bzw. das jeweilige Blatt 3 einen bedruckten Bereich 4, nämlich den Etikettenaufdruck 20, und einen den bedruckten Bereich 4 umlaufend umschließenden unbedruckten Bereich 5 auf, wobei der bedruckte Bereich 4 eine Außenkontur 6 aufweist. Der Etikettenaufdruck 20 weist geringfügig größere Abmessungen als das final beschnittene Etikett 2 auf. Vorliegend handelt es sich bei dem Etikett 2 um ein Etikett 2 für den Halsbereich einer Flasche.The
Die Stanzkontur 8 des ersten Konturstanzmessers 7 und die Stanzkontur 10 des zweiten Konturstanzmessers 9 sind vorliegend durch eine Skalierung annähernd ineinander überführbar, wobei die Stanzkontur 8 des ersten Konturstanzmessers 7 geringfügig größer ist als die Außenkontur 6 des bedruckten Bereichs 4 und die Stanzkontur 10 des zweiten Konturstanzmessers 9 geringfügig kleiner ist als die Außenkontur 6 des bedruckten Bereichs 4. Die Stanzkontur 10 des zweiten Konturstanzmessers 9 entspricht einer Außenkontur des finalen Etiketts 2.The punching
Beim Stanzvorgang mittels der Stanzvorrichtung gemäß
Die Stanzvorrichtung ist derart ausgebildet, dass das Pressen des vorgestanzten Stapels 11 in das zweite Konturstanzmesser 9 dadurch erfolgt, dass der Ausgangsstapel 1 beim Pressen des Ausgangsstapels 1 in das erste Konturstanzmesser 7 mittels des Stanzstempels 15 auf den vorgestanzten Stapel 11 einwirkt und diesen in das zweite Konturstanzmesser 9 presst. Beim Pressen des vorgestanzten Stapels 11 in das zweite Konturstanzmesser 9 wird ein Nutzenstapel 13 aus final gestanzten Etiketten 2 gebildet. Das zweite Konturstanzmesser 9 durchdringt dabei den vorgestanzten Stapel 11 ausschließlich in dem bedruckten Bereich 4, sodass bei diesem zweiten Stanzvorgang gebildeter zweiter Stanzabfall 14 bedruckte Bereiche 4 und unbedruckte Bereiche 5 aufweist. Exemplarisch ist dieser zweite Stanzabfall 14 für ein einzelnes Blatt 3 in der
Die Stanzvorrichtung weist eine zweite Sammeleinrichtung 18 zum Sammeln des beim zweiten Stanzvorgang gebildeten zweiten Stanzabfalls 14 auf. Um zu vermeiden, dass sich der erste Stanzabfall 12 mit dem zweiten Stanzabfall 14 vermischt und um dafür zu sorgen, dass der gebildete Stanzabfall 12, 14 der jeweiligen Sammeleinrichtung 17, 18 zuverlässig zugeführt wird, weist die Stanzvorrichtung zwei Ableitelemente 19 auf, wobei sich eines der Ableitelemente 19 von dem ersten Konturstanzmesser 7 in Richtung benachbarter Seitenwände der Sammeleinrichtungen 17, 18 erstreckt und das andere Ableitelement 19 von dem zweiten Konturstanzmesser 9 in Richtung einer der benachbarten Seitenwand gegenüberliegenden Seitenwand der zweiten Sammeleinrichtung 18 erstreckt. Bei dieser Stanzvorrichtung ist somit sichergestellt, dass in der ersten Sammeleinrichtung 17 ausschließlich unbedruckter erster Stanzabfall 12 gesammelt wird, der separat von dem zumindest teilweise bedruckten zweiten Stanzabfall 14, der in der zweiten Sammeleinrichtung 18 gesammelt wird, entsorgt werden kann. Somit können die Kosten für die Abfallentsorgung reduziert werden, da typischerweise die Kosten für die Entsorgung von bedrucktem Material teurer ist als die Entsorgung von unbedrucktem Material. Das unbedruckte Material kann durchaus als Wertstoff weiterverkauft werden. Dadurch kann durch eine Trennung von bedrucktem und unbedrucktem Abfallmaterial in der Summe Geld gespart werden.The punching device has a
