Description

Die Erfindung betrifft ein Werkzeug und ein Verfahren zur Herstellung eines Nutzens aus einem Kartonbogen gemäß den Oberbegriffen der Patentansprüche 1 beziehungsweise 9.The invention relates to a tool and a method for producing a blank from a sheet of cardboard according to the preambles of patent claims 1 and 9, respectively.

Bei der Herstellung von Nutzen aus Kartonbögen mit einem entsprechenden Werkzeug, welches üblicher Weise als Schneid-, Stanz- und/oder Rillwerkzeuge ausgebildet ist, werden oftmals kleinere Abfallteile mittels einer - an einem ersten Werkzeugteil angeordneten - entsprechenden Schneidlinienkontur vom Nutzen abgetrennt. Dabei wirkt der erste Werkzeugteil als Matrize mit einem zweiten Werkzeugteil als Patrize zusammen, zwischen welchen der jeweilige Kartonbogen angeordnet und der Nutzen durch Abtrennen des wenigstens einen Abfallteils erzeugt wird.When producing blanks from sheets of cardboard with a corresponding tool, which is usually designed as a cutting, punching and/or creasing tool, smaller waste parts are often separated from the blank by means of a corresponding cutting line contour arranged on a first tool part. The first tool part acts as a matrix together with a second tool part as a patrix, between which the respective sheet of cardboard is arranged and the blank is produced by separating the at least one waste part.

Während großer Abfall relativ leicht vom Nutzen des geschnittenen oder gestanzten Kartonbogens entfernt und abtransportiert werden kann, können bislang gerade kleine Stanzabfälle beim Weitertransport des Kartonbogens verloren gehen, was zu Verschmutzungen und weiteren Beeinträchtigungen im Herstellungsprozess führen kann.While large waste can be removed relatively easily from the blank of the cut or punched cardboard sheet and transported away, up to now it has been precisely small punching waste that can be lost during further transport of the cardboard sheet, which can lead to soiling and further impairments in the manufacturing process.

Aus der DE 10 065 457 A1 ist bereits ein Verfahren und eine Vorrichtung zur Trennung von Nutzen und Abfall eines gestanzten oder geschnittenen Materialbogens bekannt, bei der die Separierung von Nutzen und Abfall in einer Transporteinrichtung erfolgt, mittels welcher der Nutzen und der Abfall aus einer Bearbeitungseinrichtung entnommen werden, in welcher der Beschnitt des Kartonbogens erfolgt. Zur Separierung von Nutzen und Abfall weist die Transporteinrichtung dabei mehrere Anziehungsflächen mit unterschiedlichen Anziehungs- beziehungsweise Ansaugkräften auf, um die jeweiligen Kartonteile zu trennen und den Abfall aus dem Prozess zu entfernen. Aus der DE 10 2010 061991 A1 ist ein Werkzeug sowie ein Verfahren gemäß den Merkmalen der jeweiligen Oberbegriffe der Ansprüche 1 und 10 bekannt. Die EP 2 327 521 A1 beschreibt ein Verfahren zum Zurichten von Werkzeugen einer Flachbettbogenstanz- und/oder -prägemaschine. Dabei zeigt diese Druckschrift auch den prinzipiellen Aufbau einer Bogenstanz- und -prägemaschine zum Stanzen, Ausbrechen und Ablegen von Bögen aus Papier, Pappe und dergleichen.From the DE 10 065 457 A1 a method and a device for separating blanks and waste from a punched or cut sheet of material is already known, in which the blanks and waste are separated in a transport device, by means of which the blanks and waste are removed from a processing device in which the trimming of the cardboard sheet takes place. In order to separate use and waste, the transport device has several attraction surfaces with different attraction or suction forces in order to separate the respective cardboard parts and remove the waste from the process. From the DE 10 2010 061991 A1 a tool and a method according to the features of the respective preambles of claims 1 and 10 are known. the EP 2 327 521 A1 describes a method for preparing tools of a flatbed sheet punching and/or embossing machine. This publication also shows the basic structure a sheet punching and embossing machine for punching, breaking out and depositing sheets of paper, cardboard and the like.

Aufgabe der vorliegenden Erfindung ist es, eine Werkzeug und ein Verfahren zur Herstellung eines Nutzens aus einem Kartonbogen zu schaffen, mittels welchen kleinere Abfallteile auf besonders einfache und schnelle Weise aus dem Prozess entfernt werden können.The object of the present invention is to create a tool and a method for producing a panel from a sheet of cardboard, by means of which smaller pieces of waste can be removed from the process in a particularly simple and rapid manner.

Diese Aufgabe wird erfindungsgemäß durch ein Werkzeug und ein Verfahren zur Herstellung eines Nutzens aus einem Kartonbogen mit den Merkmalen der Patentansprüche 1 beziehungsweise 9 gelöst. Vorteilhafte Ausgestaltungen und günstige Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche.According to the invention, this object is achieved by a tool and a method for producing a blank from a sheet of cardboard with the features of patent claims 1 and 9, respectively. Advantageous configurations and favorable developments of the invention are the subject matter of the dependent claims.

Um ein Werkzeug zu schaffen, mittels welchem kleinere Abfallteile auf besonders einfache und schnelle Weise aus dem Prozess entfernt werden können, ist es erfindungsgemäß vorgesehen, dass in dem ersten Werkzeugteil, in welchem die Schneidlinienkontur angeordnet ist, außerdem wenigstens ein Absaugkanal einer Absaugeinrichtung vorgesehen ist, über welchen das wenigstens eine, mittels der Schneidlinienkontur abgetrennte Abfallteil absaugbar ist. Erfindungsgemäß ist es somit vorgesehen, jeweilige kleine Abfallteile unmittelbar an Ort und Stelle innerhalb des ersten Werkzeugteils beziehungsweise unmittelbar während des Prozessschrittes des Stanzens des Abfallteils vom Nutzen abzusaugen. Hierdurch ist in besonders einfacher und zuverlässiger Weise gewährleistet, dass beim Weitertransport des Bogens beziehungsweise im Weiteren Prozess keine Abfallteile verloren gehen können, welche ansonsten zu Verschmutzungen der Anlage oder zu einer Beeinträchtigung des Prozesses führen könnten.In order to create a tool by means of which smaller waste parts can be removed from the process in a particularly simple and quick manner, it is provided according to the invention that at least one suction channel of a suction device is also provided in the first tool part in which the cutting line contour is arranged, via which the at least one piece of waste separated by means of the cutting line contour can be sucked off. According to the invention, provision is therefore made for the respective small waste parts to be sucked off directly on the spot within the first tool part or directly during the process step of punching the waste part from the panel. This ensures in a particularly simple and reliable manner that no waste parts can be lost during the onward transport of the sheet or in the further process, which could otherwise lead to contamination of the system or to an impairment of the process.

Ein entsprechender Absaugkanal ist dabei relativ einfach in den entsprechenden Werkzeugteil einbringbar, und zwar insbesondere dann, wenn dieser aus mehreren Trägerplatten zusammengesetzt ist. Der Absaugkanal muss dabei nur partiell innerhalb des entsprechenden Werkzeugteils vorgesehen sein. Eine teilweise außen am Werkzeugteil angeordnete Führung des Kanals, beispielsweise mittels entsprechender Leitungen, ist ebenfalls denkbar. Dabei ist es ein weiterer Vorteil, dass der Absaugkanal relativ einfach mit der entsprechenden Absaugeinrichtung verbunden werden kann. Zudem ist der Absaugkanal über einen Längenbereich durch jeweilige Teilabsaugkanäle gebildet. Diese Teilabsaugkanäle können sich an jeweilige, umlaufend geschlossene Konturbereich der Schneidlinienkontur anschließen, so dass gleichzeitig mehrere Abfallteile vom Nutzen abgetrennt und über den jeweils zugeordneten Teilabsaugkanal abgesaugt werden können.A corresponding suction channel can be introduced relatively easily into the corresponding tool part, in particular when this is composed of several carrier plates. The suction channel only has to be provided partially within the corresponding tool part. It is also conceivable for the channel to be guided partially on the outside of the tool part, for example by means of appropriate lines. It is a further advantage that the suction channel can be connected relatively easily to the corresponding suction device. In addition the suction channel formed over a length range by respective partial suction channels. These partial suction channels can adjoin the respective circumferentially closed contour area of the cutting line contour, so that several pieces of waste can be separated from the panel at the same time and sucked off via the assigned partial suction channel.

In weiterer Ausgestaltung der Erfindung hat es sich dabei als vorteilhaft gezeigt, wenn der Absaugkanal zumindest über einen Längenbereich durch die Schneidlinienkontur gebildet ist. Somit bildet die Schneidlinienkontur den Eingang des Absaugkanals, so dass abgetrennte Abfallteile unmittelbar aus dem Beschnittbereich heraus nach hinten in den entsprechenden Werkzeugteil abtransportiert werden können. Da das jeweilige Abfallteil infolge des Beschnitts somit zwangsläufig in den Absaugkanal gedrückt wird, erfolgt die Absaugung auf besonders einfache und zuverlässige Weise. Zudem ist der Absaugkanal in seiner Form besonders günstig auf das korrespondierende Abfallteil angepasst, so dass eine infolge der Absaugung erzeugte Kraft in optimaler Weise auf das Abfallteil wirkt.In a further embodiment of the invention, it has proven to be advantageous if the suction channel is formed by the cutting line contour at least over a length region. The contour of the cutting line thus forms the entrance to the suction channel, so that separated waste parts can be transported away directly from the trimming area to the rear and into the corresponding part of the tool. Since the respective piece of waste is inevitably pressed into the suction channel as a result of the trimming, the suction takes place in a particularly simple and reliable manner. In addition, the shape of the suction channel is particularly favorably adapted to the corresponding waste part, so that a force generated as a result of the suction acts on the waste part in an optimal manner.

Eine weitere vorteilhafte Ausgestaltung der Erfindung sieht vor, dass der erste Werkzeugteil wenigstens eine, insbesondere obere Trägerplatte aufweist, in welcher der Absaugkanal zumindest über einen Längenbereich ausgebildet ist. Ein derartiger Absaugkanal innerhalb der entsprechenden Trägerplatte ist besonders einfach herstellbar.A further advantageous embodiment of the invention provides that the first tool part has at least one support plate, in particular an upper support plate, in which the suction channel is formed at least over a longitudinal area. Such a suction channel within the corresponding support plate is particularly easy to produce.

In weiterer Ausgestaltung der Erfindung weist der erste Werkzeugteil wenigstens eine, insbesondere untere Trägerplatte auf, in welcher die Schneidlinienkontur aufgenommen ist. Somit kann für die Schneidlinienkontur in einfacher Weise eine durch die Trägerplatte durchgängige Aussparung vorgesehen werden.In a further embodiment of the invention, the first tool part has at least one support plate, in particular a lower one, in which the cutting line contour is accommodated. Thus, a continuous recess through the carrier plate can be provided for the cutting line contour in a simple manner.

Als zudem vorteilhaft hat es sich gezeigt, wenn der erste Werkzeugteil zwischen der Trägerplatte, in der die Schneidlinienkontur aufgenommen ist, und der Trägerplatte, in welcher der Absaugkanal zumindest über einen Längenbereich ausgebildet ist, eine Zwischenplatte aufweist, in welcher der Absaugkanal zumindest über einen Längenbereich ausgebildet ist. Die Zwischenplatte kann somit einerseits der Abstützung der Schneidlinienkontur dienen und andererseits auf einfache Weise mit einem oder mehreren Absaugkanälen versehen werden.It has also been shown to be advantageous if the first tool part has an intermediate plate between the carrier plate, in which the cutting line contour is accommodated, and the carrier plate, in which the suction channel is formed at least over a length area, in which the suction channel is formed at least over a length area is trained. The intermediate plate can thus on the one hand the support of Serve cutting line contour and on the other hand are easily provided with one or more suction channels.

In weiterer Ausgestaltung der Erfindung weist die Schneidlinienkontur wenigstens einen umlaufend geschlossenen Konturbereich zum Abtrennen des jeweiligen Abfallteils auf, wobei der sich jeweils daran anschließende Absaugkanal beziehungsweise Teilabsaugkanal im Querschnitt größer ausgebildet ist als der zugeordnete Konturbereich. Durch diesen, vorzugsweise geringfügig größeren Querschnitt des jeweiligen Absaugkanals beziehungsweise Teilabsaugkanals in Bezug auf den jeweiligen Konturbereich der Schneidlinienkontur wird erreicht, dass die jeweils abgetrennten Abfallteile einerseits ohne innerhalb des Absaugkanals beziehungsweise Teilabsaugkanals zu verkanten, andererseits jedoch mit einer hinreichend großen Absaugkraft, von der Beschnittstelle entfernt werden.In a further embodiment of the invention, the cutting line contour has at least one circumferentially closed contour area for separating the respective waste part, with the respective adjoining suction channel or partial suction channel having a larger cross section than the associated contour area. This cross section, which is preferably slightly larger, of the respective suction channel or partial suction channel in relation to the respective contour area of the cutting line contour ensures that the respectively separated waste parts are removed from the cutting point on the one hand without tilting within the suction channel or partial suction channel and on the other hand with a sufficiently large suction force will.

Als zudem vorteilhaft hat sich eine Ausführungsform der Erfindung erwiesen, bei der der Absaugkanal einen Endkanal umfasst, welcher zu beiden Seiten hin aus der korrespondierenden Trägerplatte austritt, wobei an der einen Seite des Endkanals ein Absaugelement der Absaugeinrichtung angeschlossen ist und an der anderen Seite des Endkanals eine freie Einströmöffnung vorgesehen ist. Ein derartiger Endkanal ist zum einen sehr einfach herstellbar und eröffnet zum anderen die einfache Möglichkeit, einen kontinuierlichen Luftstrom zum Absaugen der Abfallteile zu erzeugen.An embodiment of the invention has also proven to be advantageous in which the suction channel comprises an end channel which emerges from the corresponding carrier plate on both sides, with a suction element of the suction device being connected to one side of the end channel and to the other side of the end channel a free inflow opening is provided. On the one hand, such an end channel is very easy to produce and, on the other hand, opens up the simple possibility of generating a continuous air flow for sucking off the waste parts.

Schließlich hat es sich als vorteilhaft gezeigt, den Endkanal an einer Außenseite der korrespondierenden Trägerplatte vorzusehen, an welcher ein Rahmenblech angeordnet ist. Hierdurch kann der Endkanal besonders kostengünstig erzeugt werden.Finally, it has proven to be advantageous to provide the end channel on an outside of the corresponding carrier plate, on which a frame sheet metal is arranged. As a result, the end channel can be produced in a particularly cost-effective manner.

Die vorstehend im Zusammenhang mit dem erfindungsgemäßen Werkzeug genannten Vorteile ergeben sich in ebensolcher Weise für das Verfahren zur Herstellung eines Nutzens aus einem Kartonbogen mit den Merkmalen des Patentanspruchs 10.The advantages mentioned above in connection with the tool according to the invention result in the same way for the method for producing a panel from a sheet of cardboard with the features of patent claim 10.

Zwischen die beiden Werkzeugteile 10, 12 sind jeweilige Kartonbögen zur Herstellung enstprechender Nutzen in einem kontinuierlichen Prozess einbringbar, wobei das Abtrennen von Abfallteilen und das Einbringen von Faltrillen auf im Weiteren noch näher beschriebene Weise durch eine Relativbewegung die beiden Werkzeugteile 10, 12 relativ zueinander, vorwiegend durch Bewegen des ersten Werkzeugteils 10 relativ zum zweiten Werkzeugteil 12, erfolgt. Vorliegend ist das Werkzeug zumindest teilweise offen dargestellt.In 1 is shown in a schematic sectional view of a tool for producing a panel, not shown, from a sheet of cardboard, also not shown. The tool designed here as a combined cutting, punching and creasing tool basically comprises a first, upper tool part 10 in the manner of a die and a lower tool part 12 in the manner of a patrix. Cardboard sheets can be introduced between the two tool parts 10, 12 for the production of corresponding panels in a continuous process, with the separation of waste parts and the introduction of folding grooves in a manner described in more detail below by a relative movement of the two tool parts 10, 12 relative to one another, predominantly by moving the first tool part 10 relative to the second tool part 12. In the present case, the tool is shown at least partially open.

Der obere Werkzeugteil 10 ist aus einer unteren Trägerplatte 14 und einer oberen Trägerplatte 16 unter Zwischenanordnung einer Zwischenplatte 18 zusammengesetzt. Oberseitig der oberen Trägerplatte 16 ist überdies ein Rahmenblech 20 vorgesehen. Alle Platten 14 bis 18 sind in einer Halteeinrichtung 22 mit einem seitlichen Halterahmen 24 aufgenommen und gegeneinander verspannt.The upper tool part 10 is composed of a lower support plate 14 and an upper support plate 16 with an intermediate plate 18 arranged between them. A frame plate 20 is also provided on top of the upper carrier plate 16 . All plates 14 to 18 are accommodated in a holding device 22 with a lateral holding frame 24 and braced against one another.

Die untere Trägerplatte 14 ist im vorliegenden Fall eine Multiplex - Trägerplatte mit einer zentralen, durchgängigen Aussparung 26, in welcher eine Schneidlinienkontur 28 zumindest im Wesentlichen formidentisch eingesetzt ist. Die Schneidlinienkontur 28 ist vorliegend aus einem Metallblock gebildet und umfasst im Wesentlichen drei umlaufend geschlossen Konturbereiche 30, mittel welchen jeweilige, parallel zueinander angeordnete Abfallteile (nicht dargestellt) vom Kartonbogen beziehungsweise Nutzen abtrennbar sind. Von der Schneidlinienkontur 28 sind demzufolge in der vorliegenden Schnittansicht sechs Schnittbereiche 32 der entsprechenden Schneidlinie dargestellt. Nach oben hin schließt der Metallblock der Schneidlinienkontur 28 bündig an der Oberseite der unteren Trägerplatte 14 beziehungsweise an der Unterseite der Zwischenplatte 18 ab, an welcher sich die Schneidlinienkontur 28 abstützt. Unter anderem aus diesem Grund ist die Zwischenplatte aus einem Stahlwerkstoff mit einer Härte von beispielsweise etwa 50 HRC gestaltet.In the present case, the lower support plate 14 is a multiplex support plate with a central, continuous recess 26, in which a cutting line contour 28 is used, at least essentially with the same shape. In the present case, the cutting line contour 28 is formed from a metal block and essentially comprises three circumferentially closed contour regions 30, by means of which respective waste parts (not shown) arranged parallel to one another can be separated from the cardboard sheet or panel. Consequently, in the present sectional view, six cutting regions 32 of the corresponding cutting line are shown from the cutting line contour 28 . Towards the top, the metal block of the cutting line contour 28 terminates flush on the upper side of the lower support plate 14 or on the underside of the intermediate plate 18 on which the cutting line contour 28 is supported. For this reason, among others, the intermediate plate is made of a steel material with a hardness of, for example, about 50 HRC.

Neben der zentralen Aussparung 26 für die Schneidlinienkontur 28 umfasst die untere Trägerplatte 14 weitere Aussparungen für jeweilige seitliche Schneidlinien 34 zur Abtrennung des Nutzens von einem großen Abfallstück sowie eine innenseitig davon angeordnete jeweilige Rilllinie 36 zur Erzeugung einer Faltrille in dem Nutzen.In addition to the central recess 26 for the cutting line contour 28, the lower support plate 14 includes further recesses for respective lateral cutting lines 34 for separating the panel from a large piece of waste and a respective scoring line 36 arranged on the inside thereof for producing a folding groove in the panel.

Der untere Werkzeugteil 12 umfasst vorliegend im Wesentlichen eine Gegenplatte 38, welche mit der Schneidlinienkontur 28, der jeweiligen Schneidlinie 34 und der jeweiligen Rilllinie 36 derart zusammen wirkt, das sich die gewünschten Beschnitte der Abfallteile beziehungsweise Faltrillen ergeben. Hierzu sind in der Gegenplatte 38 entsprechende Nuten 40 zum Zusammenwirken mit den Rilllinien 36 vorgesehen.In the present case, the lower tool part 12 essentially comprises a counter-plate 38, which interacts with the cutting line contour 28, the respective cutting line 34 and the respective creasing line 36 in such a way that the desired cuts of the waste parts or folding grooves result. For this purpose, corresponding grooves 40 are provided in the counter-plate 38 to interact with the scoring lines 36 .

An die durch die Schneidlinienkontur 28 gebildeten drei umlaufend geschlossenen Konturbereiche 30 zum Abtrennen des jeweiligen Abfallteils schließt sich vorliegend ein in diesem Bereich durch drei Teilabsaugkanäle 42 gebildeter Absaugkanal 44 an. Die Teilabsaugkanäle 42 beziehungsweise der hierdurch gebildete Absaugkanal 44 verlaufen somit innerhalb der Schneidlinienkontur 28 in Richtung nach oben bis zur Zwischenplatte 18, in welcher formidentisch die Teilabsaugkanäle 42 fortgesetzt sind. Ausgehend von der Zwischenplatte 18 erstrecken sich die Teilabsaugkanäle 42 über einen Längenbereich in Hochrichtung innerhalb der oberen Trägerplatte 16, bis sie in einen Endkanal 46 des Absaugkanals 44 münden.In the present case, a suction channel 44 formed by three partial suction channels 42 in this area adjoins the three circumferentially closed contour regions 30 formed by the cutting line contour 28 for separating the respective waste part. The partial suction channels 42 or the suction channel 44 formed thereby run within the cutting line contour 28 in the upward direction to the intermediate plate 18, in which the partial suction channels 42 are continued in an identical form. Starting from the intermediate plate 18 , the partial suction channels 42 extend over a length in the vertical direction within the upper support plate 16 until they open into an end channel 46 of the suction channel 44 .

Der Verlauf des Endkanals 46 ist dabei - wie auch die Form der Teilabsaugkanäle 42 - besonders günstig aus Fig. 2 erkennbar, welche die obere Trägerplatte 16 in einer schematischen Draufsicht entlang einer durch die Linie II - II in Fig. 1 repräsentierten Schnittebene zeigt. Hierbei wird insbesondere erkennbar, dass der Endkanal 46 zu beiden Seiten 48, 50 hin aus der korrespondierenden Trägerplatte 16 austritt, wobei an der einen Seite 48, 50 des Endkanals 46 ein nicht dargestelltes Absaugelement einer Absaugeinrichtung angeschlossen ist und an der anderen Seite des Endkanals 46 eine freie Einströmöffnung 52 vorgesehen ist. Das Absaugelement der Absaugeinrichtung ist dabei beispielsweise mit einem nachfolgenden, weiteren Absaugkanal 54 der Absaugeinrichtung, welcher in dem Halterahmen 24 verläuft, verbunden. Mittels der Absaugeinrichtung kann somit ein kontinuierlicher Absaug-Luftstrom innerhalb des Endkanals 46 von der Einströmöffnung 52 zum Absaugelement hin, also von der einen zur anderen Seite 48, 50 des Trägerelements 16, erzeugt werden.The course of the end channel 46 is particularly favorable, as is the shape of the partial suction channels 42 2 recognizable, which the upper support plate 16 in a schematic plan view along a line through the line II - II in 1 represented cutting plane shows. It is particularly evident here that the end channel 46 emerges from the corresponding carrier plate 16 on both sides 48, 50, with a suction element (not shown) of a suction device being connected to one side 48, 50 of the end channel 46 and to the other side of the end channel 46 a free inflow opening 52 is provided. The suction element of the suction device is connected, for example, to a subsequent, further suction channel 54 of the suction device, which runs in the holding frame 24 . By means of the suction device, a continuous flow of suction air can thus be generated within the end channel 46 from the inflow opening 52 to the suction element, ie from one side 48, 50 of the carrier element 16 to the other.

Es ist klar, dass der Luftstrom innerhalb des Endkanals nicht nur durch Absaugen, sondern auch durch Einblasen von Luft an der einen Seite 48, 50 erzeugt werden könnte. Auch durch einen derart eingeblasenen Luftstrom lässt sich somit ein Absaugeffekt der Absaugeinrichtung an den Konturbereichen 30 der Schneidlinienkontur 28 beziehungsweise innerhalb der Teilabsaugkanäle 42 erzielen.It is clear that the air flow within the end channel could be generated not only by suction but also by blowing in air on one side 48, 50. A suction effect of the suction device on the contour regions 30 of the cutting line contour 28 or within the partial suction channels 42 can thus also be achieved by means of an air flow blown in in this way.

Die Kraft dieses Absaug-Luftstroms wirkt im Weiteren über die Teilabsaugkanäle 42 bis im Bereich der jeweiligen Konturbereiche 30 der Schneidlinienkontur 28, mittels welchen die jeweiligen Abfallteile vom Nutzen abgetrennt werden. Die Abfallteile werden dabei beim Stanzen beziehungsweise Schneiden in die Teilabsaugkanäle 42 hinein gedrückt und durch den Absaug-Luftstrom weiter nach oben zum Endkanal 46 transportiert, von wo aus der weitere Abtransport über die Absaugeinrichtung erfolgt.The force of this suction air flow also acts via the partial suction channels 42 to the area of the respective contour areas 30 of the cutting line contour 28, by means of which the respective waste parts are separated from the benefit. During the punching or cutting process, the waste parts are pressed into the partial suction channels 42 and transported further upwards by the suction air flow to the end channel 46, from where further removal takes place via the suction device.

Um ein besonders günstiges Absaugen der Abfallteile zu erreichen, sind - wie dies insbesondere aus Fig. 3 anhand einer auschnittsweisen und gegenüber Fig. 1 vergrößerten Darstellung des Werkzeugs im Bereich der Schneidlinienkontur 28 erkennbar ist - die Teilabsaugkanäle 42 im Querschnitt größer ausgebildet ist als die zugeordneten Konturbereiche 30 der Schneidlinienkontur 28. Aus diesem Grund sind in der Draufsicht von Fig.2 auch Doppellinien in Bereich der Teilabsaugkanäle 42 erkennbar, da eine jeweils innere Linie den jeweiligen Konturbereich 30 der Schneidlinienkontur 28 zeigt.In order to achieve a particularly favorable suction of the waste parts - like this in particular 3 using a snippet and opposite 1 Enlarged view of the tool in the area of the cutting line contour 28 can be seen - the partial suction channels 42 is designed to be larger in cross section than the associated contour areas 30 of the cutting line contour 28. For this reason, in the top view of Fig.2 double lines can also be seen in the area of the partial suction channels 42, since a respective inner line shows the respective contour area 30 of the cutting line contour 28.

In Zusammenschau der Fig. 1 und 2 ist zudem erkennbar, dass der Endkanal 46 an einer Außenseite 56 der korrespondierenden Trägerplatte 16 vorgesehen ist. Dieser ist somit besonders einfach herstellbar, indem er durch das Rahmenblech 20 nach oben hin verschlossen ist. Die obere Trägerplatte 16 ist vorliegend aus einer Aluminiumlegierung gebildet, welche ein einfaches Bearbeiten ermöglicht.In synopsis of Figures 1 and 2 it can also be seen that the end channel 46 is provided on an outer side 56 of the corresponding carrier plate 16 . This is therefore particularly easy to produce in that it is closed off at the top by the frame sheet metal 20 . The upper carrier plate 16 is presently formed from an aluminum alloy, which allows for easy machining.

Insgesamt ist somit erkennbar, dass vorliegend ein Verfahren geschaffen werden kann, bei dem mit der Schneidlinienkontur 28 des ersten Werkzeugteils 10 wenigstens ein Abfallteil vom Nutzen durch Zusammenwirken mit dem zweiten Werkzeugteil 12 abgetrennt werden kann, welches hierbei in den entsprechenden Teilabsaugkanal 42 nach hinten beziehungsweise oben gedrückt und von hier aus über dem Absaugkanal 44 abgesaugt wird.Overall, it can therefore be seen that a method can be created in the present case in which at least one piece of waste can be separated from the panel using the cutting line contour 28 of the first tool part 10 by interacting with the second tool part 12, which in this case is directed backwards or upwards into the corresponding partial suction channel 42 is pressed and sucked off from here via the suction channel 44 .

Das vorliegende Werkzeug kann insbesondere zum Bearbeiten von Materialbögen aus Papier oder Karton in Stärken zwischen 80 gr/m2 und 500 gr/m2 beziehungsweise mit einer Materialstärke zwischen etwa 80 µm bis 700 µm zum Einsatz kommen. Die Materialbögen können hierbei insbesondere auch sowohl bedruckt und lackiert sein als auch beschichtet mit einer Polymerschicht oder mit einem Kunststofffilm. Ebenso können die Materialbögen eine Beschichtung mit einen Metallfilm, beispielsweise aus einem Aluminiummaterial, aufweisen. Natürlich sind auch Kombinationen der beschriebenen Materialien bei einem entsprechenden Materialbogen zum Einsatz kommen. Schließlich können die Materialbögen auch aus einem Laminat gebildet sein oder einen Verbundaufbau aufweisen.The present tool can be used in particular for processing material sheets made of paper or cardboard with thicknesses between 80 g/m 2 and 500 g/m 2 or with a material thickness between about 80 μm and 700 μm. The sheets of material can in particular also be both printed and varnished and also coated with a polymer layer or with a plastic film. Likewise, the material sheets can have a coating with a metal film, for example made of an aluminum material. Of course, combinations of the materials described are also possible are used with a corresponding material sheet. Finally, the sheets of material can also be formed from a laminate or have a composite structure.
