- Crimping grooves in foldable materials such as cardboard or paperboard when erecting a blank made of this material during the manufacture of a package, provide for a defined shape of that package.
- the contours of the blank are usually produced by means of a punching tool, while the folding grooves are introduced into the material with a scoring tool.
- the creasing and punching tools are often combined in such a way that the punching step and the impressing of the folding grooves takes place simultaneously or within the same process step.

- the creasing plates each comprise one or more creasing contours which, in cooperation with a counter-plate of the creasing tool, emboss corresponding folding grooves in the foldable material.
- Each scoring plate is mounted resiliently on an elastomer plate with a predetermined spring constant on the support plate.
- the elastomeric plate is compressed due to the application of force to the scoring plate during the embossing process, which shortens the distance between the scoring plate and the carrier plate.

Description
Die Erfindung betrifft ein Rill- und Prägewerkzeug zum Prägen von Faltrillen in faltbare Materialien gemäß dem Oberbegriff des Patentanspruchs 1. Die Erfindung betrifft weiterhin einen Zuschnitt zur Herstellung einer Verpackung sowie eine Verwendung des Rill- und Prägewerkzeugs zur Herstellung eines Zuschnitts für eine Verpackung.The invention relates to a creasing and embossing tool for embossing folding grooves in foldable materials according to the preamble of claim 1. The invention further relates to a blank for producing a packaging and a use of the creasing and embossing tool for producing a blank for packaging.
Faltrillen in faltbaren Materialien wie beispielsweise Karton oder Pappe sorgen beim Aufrichten eines aus diesem Material bestehenden Zuschnitts während der Herstellung einer Verpackung für eine definierte Form dieser Verpackung. Die Konturen des Zuschnitts werden üblicherweise mit Hilfe eines Stanzwerkzeugs hergestellt, während die Faltrillen mit einem Rillwerkzeug in das Material eingebracht werden. Die Rill- und Stanzwerkzeuge sind dabei häufig derart kombiniert, dass der Stanzschritt und das Einprägen der Faltrillen gleichzeitig bzw. innerhalb desselben Verfahrensschritts erfolgt. Ein Rillwerkzeug ist beispielsweise bereits aus der
Als nachteilig an dem bekannten Rillwerkzeug ist der Umstand anzusehen, dass die Elastomerplatte nach einer gewissen Anzahl an Prägehüben getauscht werden muss, wodurch erhöhte Ersatzteil- und Montagekosten entstehen. Da sich mit der Zeit auch die Elastizität und Federwirkung der Elastomerplatte verändern, kann zudem die Maßhaltigkeit des Rillwerkzeugs nicht über einen längeren Zeitraum garantiert werden. Die Alterung der Elastomerplatte führt dabei aufgrund der veränderlichen Toleranzen zu vergleichsweise unregelmäßigen Prägeergebnissen, was eine häufige Nachjustierungen des Rillwerkzeugs erforderlich machen. Zudem muss insgesamt mehr Druck auf die Rillplatte ausgeübt werden, um die Federwirkung der Elastomerplatte zu überwinden. Bei Leerhüben führt dies zu einer sehr starken Beanspruchung der Schneiden von Stanzmessern, die bei bekannten Rillwerkzeugen ebenfalls vorhanden sein können.A disadvantage of the known scoring tool is the fact that the elastomeric plate must be replaced after a certain number of coining strokes, resulting in increased spare parts and assembly costs. In addition, since the elasticity and spring action of the elastomer plate change with time, the dimensional accuracy of the scoring tool can not be guaranteed over a longer period of time. The aging of the elastomer plate Due to the variable tolerances, this leads to comparatively irregular embossing results, which necessitate frequent readjustments of the scoring tool. In addition, a total of more pressure must be exerted on the grooved plate in order to overcome the spring action of the elastomer plate. With empty strokes, this leads to a very high stress on the cutting edges of punching knives, which may also be present in known scoring tools.
Aufgabe der vorliegenden Erfindung ist es, ein Rill- und Prägewerkzeug der eingangs genannten Art zu schaffen, welches eine erhöhte Haltbarkeit besitzt und während seines Betriebs geringere Einstellungs- und Wartungskosten verursacht.Object of the present invention is to provide a creasing and embossing tool of the type mentioned, which has an increased durability and causes lower Einstellungs- and maintenance costs during its operation.
Die Aufgaben werden erfindungsgemäß durch ein Rill- und Prägewerkzeug zum Prägen von Faltrillen in faltbare Materialien mit den Merkmalen des Patentanspruchs 1 sowie durch die im Patentanspruch 12 angegebene Verwendung des erfindungsgemäßen Rill- und Prägewerkzeugs zur Herstellung eines Zuschnitts gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.The objects are achieved by a creasing and embossing tool for embossing folding grooves in foldable materials with the features of claim 1 and by the use specified in
Ein Rill- und Prägewerkzeug, welches eine erhöhte Haltbarkeit besitzt und während seines Betriebs geringere Einstellungs- und Wartungskosten verursacht, ist erfindungsgemäß dadurch geschaffen, dass die Rillplatte steif an der Trägerplatte abgestützt ist, so dass ein Abstand zwischen der Rillplatte und der Trägerplatte bei einer Kraftbeaufschlagung der Rillplatte während eines Prägeschritts gegenüber einem Abstand zwischen der Rillplatte und der Trägerplatte im Ruhezustand unverändert oder zumindest im Wesentlichen unverändert bleibt. Mit anderen Worten ist es erfindungsgemäß vorgesehen, dass die Rillplatte nicht federnd nachgiebig an der Trägerplatte gehalten ist. Das Rill- und Prägewerkzeug ist somit frei von elastischen oder nachgiebigen Dämpfungselementen, federnden Zwischenlagen oder dergleichen zwischen der Rillplatte und der Trägerplatte ausgebildet. Durch die steife Anbindung der Rillplatte an die Trägerplatte ist eine langfristige, toleranzenfreie Verwendung des Rill- und Prägewerkzeugs ohne die Notwendigkeit von Nachjustierungen ermöglicht. Weiterhin entfällt der bislang erforderliche regelmäßige Austausch von Elastomerplatten oder dergleichen, wodurch erhebliche Zeit- und Kostenvorteile erzielt und die Stückkosten der mit Hilfe des erfindungsgemäßen Rill- und Prägewerkzeugs gerillten Zuschnitte entsprechend stark gesenkt werden. Des Weiteren kann das erfindungsgemäße System vorteilhafterweise mit einem geringeren Gesamtdruck gefahren werden. Des Weiteren ist erfindungsgemäß vorgesehen, dass dem Rill- und Prägewerkzeug ein Stanzwerkzeug zum Trennen des faltbaren Materials, insbesondere zum Zuschneiden eines Materialbogens, zugeordnet ist. Hierdurch kann das faltbare Material besonders schnell und einfach in einem Verfahrensdurchgang gerillt und zugeschnitten werden. Das Zuschneiden des faltbaren Materials wird zusätzlich vereinfacht, indem wenigstens ein Steg eine Öffnung umfasst und/oder zusammen mit der Rillplatte eine Öffnung bildet, in welche ein Stanzmesser des zugeordneten Stanzwerkzeugs eindringen kann.A creasing and embossing tool, which has an increased durability and causes lower adjustment and maintenance costs during its operation, according to the invention created by the creasing plate is rigidly supported on the support plate, so that a distance between the creasing plate and the support plate at a force application the scoring plate during an embossing step against a distance between the scoring plate and the support plate in the idle state remains unchanged or at least substantially unchanged. In other words, it is inventively provided that the groove plate is not resiliently held on the support plate. The creasing and embossing tool is thus formed free of elastic or resilient damping elements, resilient intermediate layers or the like between the creasing plate and the carrier plate. Due to the rigid connection of the scoring plate to the carrier plate is a long-term, tolerance-free use of creasing and embossing tool without the need for readjustments. Furthermore, eliminates the previously required regular replacement of elastomer plates or the like, which achieved considerable time and cost advantages and the unit cost of grooved with the aid of the creasing and embossing tool blanks are reduced accordingly. Furthermore, the system according to the invention can advantageously be operated with a lower overall pressure. Furthermore, the invention provides that the creasing and embossing tool is assigned a punching tool for separating the foldable material, in particular for cutting a material sheet. As a result, the foldable material can be grooved and cut particularly quickly and easily in a single pass. The cutting of the foldable material is additionally simplified in that at least one web comprises an opening and / or together with the scoring plate forms an opening into which a punching knife of the associated punching tool can penetrate.
Weitere Vorteile ergeben sich, indem zwischen der Trägerplatte und der Rillplatte wenigstens ein Grundelement angeordnet ist, mittels welchem eine relative Position der Rillplatte gegenüber der Trägerplatte eingestellt ist, wobei das Grundelement aus einem steifen Material besteht. Mit Hilfe des oder der Grundelemente ist eine einfache Einstellung des Abstands zwischen der Rillplatte und der Trägerplatte ermöglicht. Da das Grundelement steif ausgebildet ist und somit bei einer Kraftbeaufschlagung der Rillplatte nicht nachgibt, bleibt der Abstand zwischen der Rillplatte und der Trägerplatte auch während der Verwendung des Rill- und Prägewerkzeugs zuverlässig konstant. Das Grundelement fungiert dementsprechend als eine Art Fundament für die Rillplatte.Further advantages are obtained by arranging at least one base element between the carrier plate and the scoring plate, by means of which a relative position of the scoring plate relative to the carrier plate is set, wherein the base element consists of a stiff material. With the help of the basic elements or a simple adjustment of the distance between the grooved plate and the carrier plate is possible. Since the base element is rigid and thus does not give way when a force is applied to the scoring plate, the distance between the scoring plate and the carrier plate remains reliably constant even during use of the scoring and embossing tool. Accordingly, the basic element acts as a kind of foundation for the scoring plate.
In einer weiteren vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass das Grundelement aus einem Metall oder einer Metalllegierung, insbesondere aus Aluminium oder einer Aluminiumlegierung, und/oder aus einem formfesten Kunststoffmaterial und/oder aus einer Keramik besteht. Hierdurch ist sichergestellt, dass das oder die Grundelemente in einer großen Formenvariation und kostengünstig herstellbar sind und gleichzeitig eine hohe Haltbarkeit und Steifigkeit besitzen.In a further advantageous embodiment of the invention, it is provided that the base element consists of a metal or a metal alloy, in particular of aluminum or an aluminum alloy, and / or of a dimensionally stable plastic material and / or of a ceramic. This ensures that the one or more basic elements in a large variety of shapes and inexpensive to produce and at the same time have a high durability and rigidity.
In einer weiteren vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass das Grundelement eine vorzugsweise durch Erodieren hergestellte Aluminiumplatte ist. Ein als Aluminiumplatte ausgebildetes Grundelement bietet dabei den Vorteil einer hohen Steifigkeit bei gleichzeitig geringem Eigengewicht. Dementsprechend ist die beim Rillen bewegte Masse des Rill- und Prägewerkzeugs vergleichsweise gering, ohne dass Einbußen bei der mechanischen Steifigkeit in Kauf genommen werden müssen. Indem die Aluminiumplatte durch ein Erodierverfahren hergestellt ist, können auch komplexe Konturen schnell und kostengünstig hergestellt werden. Alternativ oder zusätzlich kann jedoch beispielsweise auch vorgesehen sein, dass die Aluminiumplatte durch ein Urformverfahren, insbesondere durch ein Guss- bzw. Druckgussverfahren, und/oder durch ein Trennverfahren, insbesondere durch Spanen, hergestellt ist.In a further advantageous embodiment of the invention, it is provided that the base element is preferably made by eroding aluminum plate. A basic element designed as an aluminum plate offers the advantage of high rigidity low weight at the same time. Accordingly, the mass of the creasing and embossing tool moved during the creasing is comparatively small, without having to accept losses in the mechanical rigidity. By making the aluminum plate by an erosion process, even complex contours can be produced quickly and inexpensively. Alternatively or additionally, however, it can also be provided, for example, that the aluminum plate is produced by a primary shaping method, in particular by a casting or pressure casting method, and / or by a separation method, in particular by machining.
In einer weiteren vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass eine Kontur des Grundelements an eine Kontur der Rillplatte angepasst ist. Mit anderen Worten ist es vorgesehen, dass das Grundelement und die Rillplatte eine zumindest im Wesentlichen ähnliche oder identische Kontur aufweisen, so dass die Rillplatte möglichst über ihre gesamte Auflagefläche am Grundelement abgestützt ist. Hierdurch ist eine mechanisch besonders steife Anbindung zwischen der Rillplatte und dem Grundelement gegeben. Des Weiteren ist hierdurch eine modulare Ausgestaltung des Rill- und Prägewerkzeugs mit einer einfach veränderbaren Anzahl an gegebenenfalls unterschiedlich ausgestalteten Rillplatten, die jeweils über ein zugeordnetes Grundelement an der Trägerplatte abgestützt sind, ermöglicht.In a further advantageous embodiment of the invention, it is provided that a contour of the base element is adapted to a contour of the scoring plate. In other words, it is provided that the base element and the scoring plate have an at least substantially similar or identical contour, so that the scoring plate is supported as possible over its entire bearing surface on the base member. This results in a mechanically particularly rigid connection between the scoring plate and the base element. Furthermore, this is a modular design of the creasing and embossing tool with a simple variable number of optionally differently designed scoring plates, which are each supported via an associated base member on the support plate, allows.
In einer weiteren vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass das Rill- und Prägewerkzeug Mittel zum maßgenauen Anordnen des Grundelements und der Rillplatte zueinander und/oder Mittel zum Festlegen des Grundelements und/oder der Rillplatte an der Trägerplatte umfasst.

As a result, the creasing and embossing tool can be equipped particularly quickly, reliably and without complex adjustment measures with one or more creasing plates or with a corresponding number of basic elements.
In einer weiteren vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass die Trägerplatte wenigstens eine Aufnahme umfasst, in welcher die Rillplatte und gegebenenfalls das wenigstens eine Grundelement angeordnet sind. Dies ermöglicht es, die Rillplatte und ein gegebenenfalls vorhandenes Grundelement durch einfaches Anordnen in der Aufnahme ohne aufwändige Einstellmaßnahmen an der Trägerplatte zu positionieren.In a further advantageous embodiment of the invention it is provided that the support plate comprises at least one receptacle in which the scoring plate and optionally the at least one base element are arranged. This makes it possible to position the scoring plate and an optional basic element by simple arrangement in the receptacle without complex adjustment measures on the support plate.
In einer weiteren vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass eine Kontur der Aufnahme, eine Kontur der Rillplatte und gegebenenfalls eine Kontur des wenigstens einen Grundelements aneinander angepasst sind. Hierdurch können die Rillplatte und - falls vorhanden - das oder die Grundelemente besonders einfach und maßhaltig in der Aufnahme an der Trägerplatte angeordnet werden. Darüber hinaus ist durch die aneinander angepassten Konturen sichergestellt, dass sich die Rillplatte und gegebenenfalls das oder die Grundelemente auch im Fall einer Kraftbeaufschlagung während des Rillens seitlich bzw. umfänglich abgestützt sind und sich nicht relativ zur Trägerplatte bewegen können.In a further advantageous embodiment of the invention, it is provided that a contour of the receptacle, a contour of the scoring plate and possibly a contour of the at least one basic element are adapted to one another. As a result, the scoring plate and - if present - the or the basic elements are particularly simple and dimensionally stable in the recording on the support plate can be arranged. In addition, it is ensured by the matched contours that the creasing plate and possibly the one or more basic elements are laterally or circumferentially supported even in the case of a force during grooving and can not move relative to the support plate.
In einer weiteren vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass die wenigstens eine Aufnahme durch eine Ausnehmung in der Trägerplatte gebildet ist.In a further advantageous embodiment of the invention it is provided that the at least one receptacle is formed by a recess in the carrier plate.
In einer weiteren vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass zwischen der Trägerplatte und der Rillplatte wenigstens ein Ausgleichselement angeordnet ist. Hierdurch ist eine einfache Einstellung des Abstands zwischen der Trägerplatte und der Rillplatte und somit ein einfacher Toleranzausgleich ermöglicht. Vorzugsweise ist das Ausgleichselement eine Kunststoff- oder Metallfolie mit einer Stärke zwischen 0,05 mm und 20,0 mm. Es ist aber auch möglich, dass das Ausgleichselement aus Papier oder Keramik besteht. Auch andere Materialien sind denkbar. Zudem ist das Ausgleichselement insbesondere kalibriert ausgebildet. Um dies steife Kopplung zwischen der Trägerplatte und der Rillplatte gewährleisten zu können, sollte natürlich auch das Ausgleichselement grundsätzlich nicht federnd nachgiebig ausgebildet sein. Ein als unelastische Kunststoff- oder Metallfolie ausgebildetes Ausgleichselement eignet sich besonders zur Höhenkorrektur bzw. zum einfachen Einstellen des Abstands zwischen der Rillplatte und der Trägerplatte. Beispielsweise können mehrere Ausgleichselemente mit einer jeweiligen Dickendifferenz von 0,05 mm oder einer anderen geeigneten Dickendifferenz bereitgestellt und bedarfsweise gegeneinander ausgetauscht werden, um den Abstand zwischen der Rillplatte und der Trägerplatte auf einen gewünschten Wert einzustellen. Des Weiteren ermöglicht das Ausgleichselement eine einfache Anpassung des Abstands zwischen der Trägerplatte und der Rillplatte für unterschiedliche Ausgestaltungen eines gegebenenfalls vorhandenen Grundelements. Es kann dabei vorgesehen sein, dass das Ausgleichselement zwischen der Trägerplatte und dem Grundelement und/oder zwischen dem Grundelement und der Rillplatte angeordnet wird. Alternativ oder zusätzlich kann vorgesehen sein, dass mehrere gleich oder unterschiedlich dicke Ausgleichselemente zum Toleranzausgleich verwendet werden. Es kann weiterhin vorgesehen sein, dass eine Kontur des Ausgleichselements an eine Kontur der Rillplatte und/oder des Grundelements und/oder einer Aufnahme der Trägerplatte angepasst ist.In a further advantageous embodiment of the invention, it is provided that at least one compensation element is arranged between the carrier plate and the scoring plate. As a result, a simple adjustment of the distance between the support plate and the scoring plate and thus a simple tolerance compensation is possible. Preferably, the compensation element is a plastic or metal foil with a thickness between 0.05 mm and 20.0 mm. But it is also possible that the compensation element made of paper or ceramic. Other materials are conceivable. In addition, the compensation element is designed in particular calibrated. In order to be able to ensure this rigid coupling between the support plate and the scoring plate, of course, the compensating element should in principle not be resiliently designed. A designed as inelastic plastic or metal foil compensation element is particularly suitable for height correction or for easy adjustment of the distance between the groove plate and the support plate. For example, several compensating elements with a respective thickness difference of 0.05 mm or other suitable thickness difference can be provided and, if necessary, interchanged to set the distance between the scoring plate and the carrier plate to a desired value. Furthermore, the compensation element allows easy adjustment of the distance between the carrier plate and the scoring plate for different configurations of an optional basic element. It can be provided that the compensation element between the support plate and the base member and / or between the base member and the scoring plate is arranged. Alternatively or additionally, it can be provided that a plurality of equal or different thickness compensation elements are used for tolerance compensation. It may further be provided that a contour of the compensating element is adapted to a contour of the scoring plate and / or the base element and / or a receptacle of the carrier plate.
