Description

Die Erfindung betrifft ein Stanz- und Rillwerkzeug zur Herstellung von gerillten Stanzteilen nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a stamping and creasing tool for producing grooved stamped parts according to the preamble of patent claim 1.

Faltschachtelzuschnitte aus Karton erhalten üblicherweise Rillungen, durch die die Faltschachteln beim späteren Aufrichten ihre definierte Form erhalten. Die Konturen sowie notwendige Einschnitte des Faltschachtelzuschnitts werden durch Stanzen erzeugt. Die Herstellung erfolgt mittels Bandstahl-Stanz-und Rill-Werkzeugen auf Flachbett- bzw. Rotationsstanzen.Folding box blanks made of cardboard are usually given creases, which give the folding boxes their defined shape when they are later erected. The contours as well as the necessary incisions of the folding box blank are created by punching. The production takes place by means of band steel stamping and creasing tools on flat bed or rotary stamping.

Die Bandstahl-Stanz- und Rill-Werkzeuge bestehen üblicherweise aus einer Trägerplatte beispielsweise aus Holz, Verbunden aus Kunststoffen mit Glasgewebe oder in Sandwichbauweise mit Metallplatten armiert. In diese Trägerplatten werden entsprechend den Schachtelkonturen Schlitze eingebracht, die denen Stanz- bzw. Rillinien aufgenommen werden. Die Stanzlinien stehen entweder genau so weit oder weiter von der Trägerplatte vor wie die Rillinien. Die Stanzlinien arbeiten gegen eine Stanzplatte, überwiegend aus Stahl.The band steel punching and creasing tools usually consist of a carrier plate made of wood, for example, bonded from plastics with glass fabric or sandwiched with metal plates. In accordance with the box contours, slots are made in these carrier plates to accommodate the punching or creasing lines. The punched lines either protrude as far as or farther from the carrier plate than the crease lines. The punching lines work against a punching plate, mainly made of steel.

Solche Werkzeuge sind beispielsweise in den Patentschriften DE 39 28 916 C1 oder DE 38 31 393 A1 dargestellt.Such tools are shown for example in the patents DE 39 28 916 C1 or DE 38 31 393 A1.

Die Rillinien erzeugen eine Rillung im Faltschachtelmaterial dadurch, daß sie das Material in eine Rillnut drücken. Diese Rillnuten können in die Stanzplatte eingefräst oder als Aufbau auf der Stanzplatte angebracht sein. Das Faltschachtelmaterial soll entlang der Rillungen exakt und mit einem definierten Faltwiderstand faltbar sein. Dem Faltvorgang kommt insbesondere in Kartonierautomaten eine besondere Bedeutung zu, da von der Exaktheit und dem Faltverhalten der Rillungen die erreichbare Arbeitsgeschwindigkeit der Kartonierautomaten abhängt.The creasing lines create a creasing in the folding box material by pressing the material into a creasing groove. These creases can be milled into the punching plate or as a structure be attached to the punching plate. The folding box material should be able to be folded exactly along the creases and with a defined folding resistance. The folding process is particularly important in cartoning machines, since the achievable working speed of the cartoning machines depends on the exactness and the folding behavior of the creases.

Probleme bei der Erzeugung exakter Rillinien ergeben sich bei den bekannten Bandstahl-Stanz-und Rill-Werkzeugen aus dem Zusammenwirken von Rillinien und Rillnut. Die Rillinie ist Bestandteil der Trägerplatte während die Rillnuten auf der Stanz-Rillplatte angebracht sind. Die Schlitze für die Aufnahme der Rillinien werden z.B. mit Laser NC-gesteuert in die Trägerplatte eingebracht. Mit demselben Programm werden die Rillnuten NC-gesteuert in die Stanz-Rillplatte eingearbeitet. Bei der Ausrichtung der Trägerplatte zur Stanz-Rillplatte ist es trotzdem nicht zu verhindern, daß die Rillinien in der Trägerplatte nicht an jeder Stelle exakt mittig zur zugehörigen Rillnut plaziert sind. Dies ist unvermeidbar, da die Rillinien in den Schlitzen der Trägerplatte durch Klemmsitz gehalten werden. Dadurch entstehen bei einer Vielzahl von parallel laufenden Rillinien seitliche Verspannungen, die geringfügige Versetzungen zur Folge haben. Die Rillinien müssen deshalb zum Teil von Hand nachgerichtet oder die Rillnutbreiten müssen dementsprechend angepaßt sein. Dies ist jedoch ungünstig, da eine möglichst schmale Rillung gewünscht ist, um eine genaue und symetrische Faltkante zu erreichen.Problems in the production of exact creasing lines arise in the known band steel punching and creasing tools from the interaction of creasing lines and creasing groove. The creasing line is part of the carrier plate while the creasing grooves are attached to the punching-creasing plate. The slots for receiving the creasing lines are e.g. brought into the carrier plate with NC controlled laser. With the same program, the creasing grooves are machined into the punched-creasing plate under NC control. When aligning the carrier plate to the punch-crease plate, it is nevertheless not possible to prevent the crease lines in the carrier plate from not being placed exactly in the middle of the associated crease groove at every point. This is unavoidable since the creasing lines are held in the slots in the carrier plate by a clamp fit. This creates lateral tension in a large number of creasing lines running in parallel, which result in slight dislocations. The creasing lines must therefore be partially adjusted by hand or the creasing widths must be adjusted accordingly. However, this is disadvantageous, since the smallest possible crease is desired in order to achieve a precise and symmetrical folded edge.

Der Erfindung liegt die Aufgabe zugrunde, ein Stanz- und Rillwerkzeug zu schaffen, mit dem sich gerillte Stanzteile mit hoher Rillengüte herstellen lassen.The invention has for its object to provide a punching and creasing tool with which grooved stamped parts can be produced with high quality.

Diese Aufgabe wird durch ein Stanz- und Rillwerkzeug mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen des erfindungsgemäßen Stanz- und Rillwerkzeuges sind Gegenstand der Patentansprüche 1 bis 8.This object is achieved by a punching and creasing tool with the features of patent claim 1. Advantageous configurations of the punching and creasing tool according to the invention are the subject of claims 1 to 8.

Die erfindungsgemäße Ausgestaltung des Stanz- und Rillwerkzeuges ermöglicht eine exakte Ausrichtung der Rillvorsprünge bezüglich der in der Stanz-Rillplatte ausgebildeten Rillnuten. In der Trägerplatte sind nur noch Schlitze für die Stanzelemente vorzusehen. Hierdurch wird die Anzahl der Schlitze deutlich reduziert, so daß die Trägerplatte eine hohe Steifigkeit aufweist, die eine genaue Ausrichtung der Rillinien gewährleistet.The inventive design of the punching and creasing tool enables exact alignment of the creasing projections with respect to the creasing grooves formed in the punching-creasing plate. Only slots for the punching elements have to be provided in the carrier plate. As a result, the number of slots is significantly reduced, so that the carrier plate has a high degree of rigidity, which ensures precise alignment of the creasing lines.

Es ist möglich, für jeden zu stanzenden Nutzen eine eigene Rillungsplatte vorzusehen.It is possible to provide a separate crease plate for each blank to be punched.

Wenn in der Rillungsplatte Zentrierbohrungen vorgesehen sind, die mit in der Stanz-Rillplatte ausgebildeten ersten Zentrieröffnungen fluchten, wenn die Rillungsplatte so angeordnet ist, daß die Rillvorsprünge exakt zu den entsprechenden Rillnuten ausgerichtet sind, können durch die Zentrierbohrungen und die ersten Zentrieröffnungen hindurchgehende Paßstifte zur Fixierung der Rillungsplatte auf der Stanz-Rillplatte eingesetzt werden. Der Abstand der Rillungsplatte zur Stanz-Rillplatte läßt sich dabei durch Distanzscheiben einstellen, durch die die Paßstifte hindurchgehen.If centering holes are provided in the grooved plate, which are aligned with the first centering openings formed in the stamped-grooved plate, if the grooved plate is arranged such that the grooved projections are exactly aligned with the corresponding grooved grooves, dowel pins passing through the centering holes and the first centering openings can be used for fixing the grooved plate can be used on the punched-grooved plate. The distance between the grooved plate and the punched-grooved plate can be adjusted using spacers through which the dowel pins pass.

Die Trägerplatte kann mittels Paßstiften exakt zur Stanz-Rillplatte ausgerichtet werden, wenn in der Trägerplatte Zentrierbohrungen vorgesehen sind, die mit in der Stanz-Rillplatte ausgebildeten zweiten Zentrieröffnungen fluchten. Hierdurch wird es ermöglicht, die Trägerplatte in einer genau definierten Position mit der auf der Stanz-Rillplatte fixierten Rillungsplatte zu verbinden.The carrier plate can be aligned exactly with the punching-creasing plate by means of dowel pins if centering bores are provided in the carrier plate, which are aligned with second centering openings formed in the stamping-creasing plate. This enables the carrier plate to be connected in a precisely defined position to the grooved plate fixed on the stamped-grooved plate.

Diese Verbindung kann vorläufig durch ein zwischen der Trägerplatte und der Rillungsplatte vorgesehenes Klebemittel, vorzugsweise ein Doppelklebeband, erfolgen.This connection can be made temporarily by an adhesive provided between the carrier plate and the grooved plate, preferably a double-sided adhesive tape.

Nach der vorläufigen Befestigung kann die Rillungsplatte zur endgültigen Befestigung mit der Trägerplatte verschraubt werden.After the preliminary fastening, the grooved plate can be screwed to the carrier plate for final fastening.

Ein Ausführungsbeispiel der Erfindung wird nachstehend anhand von Zeichnungen näher erläutert. Es zeigt:

Die in Fig. 1 gezeigte Stanz-Rillplatte 10 ist an einer Gegendruckplatte (nicht gezeigt) eines Stanz- und Rillwerkzeuges horizontal angebracht. In der Oberfläche der Stanz-Rillplatte 10 sind mehrere Rillnuten 12 zur Ausbildung von Rillungen in einem zu bearbeitenden Flachmaterial, z.B. in einem Karton, vorgesehen. Außerhalb des mit den Rillnuten 12 vorgesehenen Bereichs sind in der Stanz-Rillplatte 10 vier vertikale erste Zentrieröffnungen 14 vorgesehen, in die jeweils ein Paßstift 20 eingesetzt ist. Oberhalb der Stanz-Rillplatte 10 ist eine Rillungsplatte 16 angeordnet, in der vertikale Zentrierbohrungen 18 ausgebildet sind, die mit den ersten Zentrieröffnungen 14 in der Stanz-Rillplatte 10 fluchten, den gleichen Durchmesser wie diese aufweisen und in die ein entsprechender in eine jeweilige erste Zentrieröffnung 14 eingesetzter Paßstift 20 eingreift.The punching-creasing plate 10 shown in FIG. 1 is horizontally attached to a counter-pressure plate (not shown) of a punching and creasing tool. In the surface of the stamped-scoring plate 10, a plurality of scoring grooves 12 are provided to form scoring in a flat material to be processed, for example in a cardboard box. Outside the area provided with the creasing grooves 12, four vertical first centering openings 14 are provided in the punching-creasing plate 10, into each of which a dowel pin 20 is inserted. A grooved plate 16 is arranged above the punched-grooved plate 10, in which vertical centering bores 18 are formed, which are aligned with the first centering openings 14 in the punched-grooved plate 10, have the same diameter as these, and into which a corresponding first centering opening 14 inserted dowel pin 20 engages.

Jeder Paßstift 20 geht durch eine Distanzscheibe 23 hindurch, die zwischen der Rillungsplatte 16 und der Stanz-Rillplatte 10 angeordnet ist.Each dowel pin 20 passes through a spacer 23, which is arranged between the grooved plate 16 and the punched-grooved plate 10.

An der Unterseite der Rillungsplatte 16 sind den Rillnuten 12 gegenüberliegend Rillvorsprünge 22 angeordnet, die jeweils exakt zur entsprechenden Rillnut 12 ausgerichtet sind. Der Abstand des freien Endes der Rillvorsprünge 22 zu dem Nutgrund der jeweiligen Rillnut 12 ist abhängig von dem zu rillenden Flachmaterial sowie der Tiefe der Rillnut 12. Dieser Abstand kann mittels der Distanzscheiben 23 eingestellt werden.On the underside of the grooved plate 16, the grooved projections 22 are arranged opposite the grooved grooves 12, each of which is exactly aligned with the corresponding grooved groove 12. The distance between the free end of the creasing projections 22 and the groove base of the respective creasing groove 12 depends on the flat material to be creased and the depth of the creasing groove 12. This distance can be set by means of the spacers 23.

Zur Fixierung der Rillungsplatte 16 auf der Stanz-Rillplatte 10 werden die Paßstifte 20 in die ersten Zentrieröffnungen 14 so eingesetzt, daß sie von der Oberseite der Stanz-Rillplatte 10 vorstehen. Anschließend werden die Distanzscheiben 23 auf die Paßstifte 20 aufgesetzt.To fix the scoring plate 16 on the punching-scoring plate 10, the dowel pins 20 are inserted into the first centering openings 14 so that they protrude from the top of the punching-scoring plate 10. Then the spacers 23 are placed on the dowel pins 20.

Schließlich wird die Rillungsplatte 16 auf die Paßstifte 20 aufgeschoben, wobei die Paßstifte 20 in die Zentrierbohrungen 18 eingreifen.Finally, the grooved plate 16 is pushed onto the dowel pins 20, the dowel pins 20 engaging in the centering holes 18.

Die an der Unterseite der Rillungsplatte 16 vorgesehenen Rillvorsprünge 22 sind in dieser Stellung exakt zu den Rillnuten 12 ausgerichtet.The creasing projections 22 provided on the underside of the creasing plate 16 are exactly aligned with the creasing grooves 12 in this position.

Anschließend wird, wie es in Fig. 2 gezeigt ist, die Trägerplatte 21 auf die Rillungsplatte 16 bzw. auf mehrere Rillungsplatten (bei mehreren Nutzen) aufgelegt. In der Trägerplatte 21 sind im Bereich oberhalb der Rillungsplatte 16 Bohrungen vorgesehen, in denen Nivellierbuchsen 34 mittels Klemmsitz befestigt sind, deren untere Stirnseiten in einer Ebene liegen und in geringem Maße von der Unterseite der Trägerplatte 21 vorstehen.Subsequently, as shown in FIG. 2, the carrier plate 21 is placed on the grooving plate 16 or on a plurality of grooving plates (with several uses). Bores are provided in the carrier plate 21 in the area above the grooved plate, in which leveling bushings 34 are fastened by means of a clamp fit, the lower end faces of which lie in one plane and protrude slightly from the underside of the carrier plate 21.

In der Trägerplatte 21 sind Zentrierbohrungen 24 vorgesehen, die mit zweiten Zentrieröffnungen 26 in der Stanz-Rillplatte 10 fluchten und denselben Durchmesser wie diese haben. Die Trägerplatte 21 ist mittels Paßstiften 28 auf der Stanz-Rillplatte 10 fixiert, die in jede Zentrierbohrung 24 und die entsprechende zweite Zentrieröffnung 26 eingreifen.Centering bores 24 are provided in the carrier plate 21, which are aligned with the second centering openings 26 in the punching-creasing plate 10 and have the same diameter as this. The carrier plate 21 is fixed by means of dowel pins 28 on the punched-grooved plate 10, which engage in each centering hole 24 and the corresponding second centering opening 26.

In der Trägerplatte 21 sind mehrere Schlitze ausgebildet, in denen jeweils eine Stanzlinie 30 so eingesetzt ist, daß ihr Rücken mit der Oberseite der Tragerplatte 21 bündig ist und die der Stanz-Rillplatte 10 zugewandte Schneide 32 die Stanzplatte 10 berührt, wenn die Trägerplatte 21 auf der Rillungsplatte 16 aufliegt. Zwischen der Rillungsplatte 16 und der Trägerplatte 21 ist ein Doppelklebeband (nicht gezeigt) angeordnet, mit dem die Rillungsplatte 16 vorläufig auf den Stirnseiten der Nivellierungsbuchsen 34 in der Trägerplatte 21 fixiert wird.A plurality of slots are formed in the carrier plate 21, in each of which a punching line 30 is inserted in such a way that its back is flush with the top of the carrier plate 21 and the cutting edge 32 facing the punching-grooving plate 10 touches the punching plate 10 when the carrier plate 21 is open the grooved plate 16 rests. A double-sided adhesive tape (not shown) is arranged between the scoring plate 16 and the carrier plate 21, with which the scoring plate 16 is temporarily fixed in the carrier plate 21 on the end faces of the leveling bushings 34.

Nach der vorläufigen Fixierung wird die Trägerplatte 21 mit der daran befestigten Rillungsplatte 16 von der Stanz-Rillplatte 10 abgehoben, und es werden die Paßstifte 20 und 28 entfernt. Nun wird die durch das Klebeband vorläufig mit der Trägerplatte 21 befestigte Rillungsplatte 16 fest durch Schrauben (nicht gezeigt) mit der Trägerplatte 21 verbunden, die durch die Durchgangsöffnungen 36 der Nivellierungsbuchsen 34 hindurchgehen und in Gewindebohrungen 38 eingreifen, die an der Oberseite der Rillungsplatte 16 vorgesehen sind.After the provisional fixation, the carrier plate 21 with the grooved plate 16 attached to it is lifted off the punched grooved plate 10, and the dowel pins 20 and 28 are removed. Now the grooved plate 16, which is temporarily fastened to the carrier plate 21 by the adhesive tape, is firmly connected to the carrier plate 21 by screws (not shown), which pass through the through openings 36 in the leveling bushings 34 and engage in threaded holes 38 provided on the top of the grooved plate 16 are.

Wenn auf diese Weise mehrere Rillungsplatten 16 in einer exakten Position an der Trägerplatte 21 befestigt werden, ist zur Ausrichtung der Rillvorsprünge 22 zu den entsprechenden Rillnuten 12 nur noch eine einmalige Ausrichtung der Trägerplatte 21 erforderlich, die mit einer Druckplatte verbunden wird.If a plurality of scoring plates 16 are fastened in this way to the carrier plate 21 in an exact position, only a one-time alignment of the carrier plate is required to align the scoring projections 22 with the corresponding scoring grooves 12 21 required, which is connected to a pressure plate.

Die Nivellierungsbuchsen 34 dienen zur Schaffung einer präzisen Auflageebene, da die Trägerplatte 21 an ihrer Unterseite Unebenheiten aufweisen kann. Falls die Trägerplatte 21 an ihrer Unterseite jedoch absolut eben ist, kann auf die Nivellierungsbuchsen 34 verzichtet werden und die Rillungsplatte 16 kann direkt an der Trägerplatte 21 befestigt werden.The leveling bushings 34 serve to create a precise support plane, since the carrier plate 21 can have unevenness on its underside. If the carrier plate 21 is absolutely flat on its underside, the leveling bushings 34 can be dispensed with and the grooved plate 16 can be attached directly to the carrier plate 21.
