Description

Die vorliegende Erfindung betrifft ein Stanz- und Rillwerkzeug, insbesondere zur Herstellung von Faltschachtelzuschnitten, mit einer Trägerplatte, in der mindestens eine Ausnehmung zur Lagerung mindestens einer Stanz- und/oder Rilllinie in Form eines Bandstahlschnitts ausgebildet ist, wobei zur klemmenden und lösbaren Halterung der Stanz- und/oder Rilllinie mindestens ein elastisches Halteelement angeordnet ist, das in die Ausnehmung und/oder in eine zusätzliche Aussparung der Trägerplatte einführbar ist und dort lösbar gehalten ist.The present invention relates to a punching and creasing tool, in particular for the production of folding box blanks, with a carrier plate in which at least one recess for mounting at least one punching and/or creasing line is formed in the form of a strip steel section, with the punch being clamped and releasably held - At least one elastic holding element is arranged and/or the crease line, which can be inserted into the recess and/or into an additional recess of the carrier plate and is held there in a detachable manner.

Derartige Stanz- und Rillwerkzeuge sind aus dem Stand der Technik, insbesondere aus US 5,275,076 A , US 3,941,038 A , US 3,479,931 A , US 5,197,367 A und CN 103406936 B bekannt und werden im Folgenden mit Bezug auf die Fig. 1 bis 3d erläutert.Such punching and creasing tools are from the prior art, in particular US 5,275,076A , US 3,941,038A , US 3,479,931A , US 5,197,367A and CN 103406936B known and are referred to below with reference to the Figures 1 to 3d explained.

Fig. 1 zeigt einen bereits gestanzten und gerillten Faltschachtelzuschnitt 1, wie er mit einem herkömmlichen Stanz- und Rillwerkzeug aus einem Flachmaterial, wie beispielsweise Karton, hergestellt werden kann. Hierzu wird das Flachmaterial in eine Stanzmaschine eingelegt, wo die äußere Form des Faltschachtelzuschnitts 1 aus dem Flachmaterial herausgestanzt wird, was in Fig. 1 mit den durchgezogenen Linien 2 angedeutet ist. Die Rilllinien durchtrennen demgegenüber nicht das Flachmaterial, sondern erzeugen einen strichliniert dargestellten Falz 3, wodurch sich der Faltschachtelzuschnitt 1 entlang der vorgegebenen Linien zu einer fertigen Schachtel zusammenfalten lässt. 1 shows a folding box blank 1 that has already been punched and scored, as can be produced from a flat material, such as cardboard, using a conventional punching and scoring tool. For this purpose, the flat material is placed in a punching machine, where the outer shape of the folding box blank 1 is punched out of the flat material, which in 1 is indicated by the solid lines 2. In contrast, the scoring lines do not cut through the flat material, but produce a fold 3 shown in dashed lines, as a result of which the folding box blank 1 can be folded along the specified lines to form a finished box.

Zur Herstellung eines solchen Faltschachtelzuschnitts 1 besitzt das Stanz- und Rillwerkzeug eine Trägerplatte 4, wie sie in einer Draufsicht in Fig. 2 schematisch dargestellt ist. Die Trägerplatte 4 weist mehrere Ausnehmungen 5 auf, die das komplette Material der Trägerplatte 4 von der Oberseite bis zur Unterseite durchgreifen. Zwischen den Ausnehmungen 5 sind Brücken 6 ausgebildet, so dass die Trägerplatte 4 in sich stabil ausgebildet ist.To produce such a folding box blank 1, the punching and creasing tool has a carrier plate 4, as shown in a plan view in 2 is shown schematically. The support plate 4 has a plurality of recesses 5 which penetrate the entire material of the support plate 4 from the top to the bottom. Bridges 6 are formed between the recesses 5, so that the support plate 4 is inherently stable.

Um eine ununterbrochene Kontur von Stanz- und Rilllinien zu schaffen, werden die Stanz- und Rilllinien in Form von Bandstahlschnitten in die Ausnehmungen 5 der Trägerplatte 4 eingesteckt, wo sie klemmend gehalten sind. Detailansichten einer Trägerplatte 4 mit einer beispielhaft dargestellten Rilllinie 7 sind in den Fig. 3a, c (Längsschnittdarstellungen) und 3b, d (Querschnittsdarstellungen) gezeigt. Dargestellt ist jeweils eine Rilllinie 7 mit einer oberen Rilllinienkante 8 und zwei Ausschneidungen 9, 9' zur Aufnahme jeweils einer Brücke 6, 6' der Trägerplatte 4. Die Rilllinie 7 wird in Pfeilrichtung 10 in die Ausnehmungen 5, 5', 5" der Trägerplatte 4 eingesteckt, so dass die Rilllinie 7 hierin kraft- bzw. reibschlüssig gehalten ist.In order to create an uninterrupted contour of punching and creasing lines, the punching and creasing lines are inserted in the form of strip steel cuts into the recesses 5 of the carrier plate 4, where they are held in a clamped manner. Detailed views of a carrier plate 4 with a score line 7 shown as an example are in FIGS Figure 3a , c (longitudinal sectional views) and 3b, d (cross-sectional views). A score line 7 is shown with an upper score line edge 8 and two cutouts 9, 9' for receiving a bridge 6, 6' of the carrier plate 4. The score line 7 is inserted in the direction of the arrow 10 into the recesses 5, 5', 5" of the carrier plate 4 inserted, so that the scoring line 7 is held here in a non-positive or frictional manner.

Die Fig. 3c und 3d zeigen das Stanz- und Rillwerkzeug im zusammengesetzten Zustand, das in Pfeilrichtung 11 Stanzhübe auf eine Konterplatte 12 ausübt. Hierzwischen eingelegtes Flachmaterial 13 wird den vorgegebenen Konturen entsprechend von Stanzlinien gestanzt. Rilllinien erzeugen demgegenüber Falze, indem die Rilllinien das Flachmaterial 13 in Nuten 14 pressen, die auf der Konterplatte 12 ausgebildet sind.the Figures 3c and 3d show the punching and creasing tool in the assembled state, which exerts punching strokes on a counter-plate 12 in the direction of the arrow 11 . Flat material 13 inserted between them is punched according to the predetermined contours by punching lines. In contrast, scoring lines produce folds in that the scoring lines press the flat material 13 into grooves 14 which are formed on the counter plate 12 .

Nachteiliger Weise ist die klemmende Halterung der Stanz- und Rilllinien innerhalb der Trägerplatte mit dem Nachteil verbunden, dass das Einbringen der Rilllinien in die Ausnehmungen zu einer unerwünschten Ausdehnung der Trägerplatte führt, weshalb die Maßhaltigkeit der Trägerplatte nicht gegeben ist. Hierdurch verändert sich nicht nur die Kontur des Stanz- und Rillverlaufs, womit ungleichmäßige Faltschachtelzuschnitte entstehen, sondern in Extremfällen verschiebt sich eine Rilllinie gegenüber der Konterplatte soweit, dass das Flachmaterial von der Rilllinie nicht mehr in die Nut gedrückt wird, sondern geschnitten wird, so dass ein sogenannter Rillbruch entsteht. Fehlchargen und unpräzise Faltschachtelzuschnitte sind die unerwünschte Folge.Disadvantageously, the clamped mounting of the stamping and creasing lines within the carrier plate has the disadvantage that the introduction of the creasing lines into the recesses leads to an undesired expansion of the carrier plate, which is why the carrier plate is not dimensionally accurate. This not only changes the contour of the punching and creasing process, resulting in uneven folding box blanks, but in extreme cases a creasing line is shifted relative to the counter plate to such an extent that the flat material is no longer pressed by the creasing line into the groove, but is cut, so that a so-called groove fracture occurs. Bad batches and imprecise folding box blanks are the undesired result.

Es ist daher die Aufgabe der vorliegenden Erfindung ein Stanz- und Rillwerkzeug anzugeben, dass eine konstante Zurichtung von Faltschachtelzuschnitten erlaubt und die Maßhaltigkeit der Trägerplatte erhöht.It is therefore the object of the present invention to specify a punching and creasing tool that allows constant trimming of folding box blanks and increases the dimensional accuracy of the carrier plate.

Diese Aufgabe wird durch das Stanz- und Rillwerkzeug nach Anspruch 1 gelöst. Erfindungsgemäß ist vorgesehen, dass das Haltelement im vertikalen Querschnitt U-förmig ausgebildet ist und zwei freie Schenkel aufweist, zwischen denen eine Nut zur Aufnahme und klemmenden Halterung der Stanz- und/oder Rilllinie ausgebildet ist. Die freien Schenkel der U-förmigen Halterung sind dabei über einen Steg miteinander verbunden, so dass das im Querschnitt U-förmige Profil entsteht. Hierdurch werden die erforderlichen Klemmkräfte nicht mehr auf die Trägerplatte übertragen, weshalb die Ausdehnung der Trägerplatte beim Einstecken der Stanz- und/oder Rilllinien verhindert und die Maßhaltigkeit erhöht wird. Die erfindungsgemäße Kombination aus Trägerplatte, elastischer Halterung und hierin gehaltener Stanz- und/oder Rilllinien erlaubt es dem System sich selbst beispielsweise im Rillkanal zu zentrieren, was die Präzession des Stanz- und Rillverlaufs erhöht. Mit anderen Worten halten die elastischen Halterungen die Stanz- und/oder Rilllinien einerseits fest, damit sie nicht aus der Trägerplatte herausfallen, und andererseits bewirken sie, dass die Stanz- und/oder Rilllinien zentriert bleiben und sich beim Stanzen ggf. selbst ausrichten können.This problem is solved by the punching and creasing tool according to claim 1. According to the invention, it is provided that the holding element is U-shaped in vertical cross section and has two free legs, between which a groove for receiving and clampingly holding the punching and/or creasing line is formed. The free legs of the U-shaped bracket are connected to one another via a web, so that the cross-sectionally U-shaped profile is formed. As a result, the required clamping forces are no longer transmitted to the carrier plate, which is why the expansion of the carrier plate when the stamping and/or creasing lines are inserted is prevented and the dimensional accuracy is increased. The inventive combination of carrier plate, elastic mount and punching and/or creasing lines held therein allows the system to center itself, for example, in the creasing channel, which increases the precession of the punching and creasing process. In other words, on the one hand, the elastic mounts hold the punching and/or creasing lines so that they do not fall out of the carrier plate, and on the other hand, they ensure that the punching and/or creasing lines remain centered and, if necessary, can align themselves during punching.

Bevorzugte Ausführungsformen der vorliegenden Erfindung werden nachfolgend und in den Unteransprüchen beschrieben.Preferred embodiments of the present invention are described below and in the subclaims.

Das Halteelement ist im Längsschnitt und/oder im horizontalen Querschnitt vorzugsweise rechteckig ausgebildet, so dass das Halteelement in eine quaderförmige Aussparung der Trägerplatte einführbar ist. Ein solches Haltelement lässt sich einfach aus einem quaderförmigen Elastomer oder Kunststoff herstellen, indem die Nut zur Aufnahme und klemmenden Halterung der Stanz- und/oder Rilllinie in den quaderförmigen Elastomer hineingeschnitten wird, so dass das U-förmige Profil des Halteelementes entsteht.The holding element is preferably rectangular in longitudinal section and/or in horizontal cross section, so that the holding element can be inserted into a cuboid recess in the carrier plate. Such a holding element can be easily produced from a cuboid elastomer or plastic by cutting the groove for receiving and clamping the punching and/or creasing line into the cuboid elastomer, so that the U-shaped profile of the holding element is created.

In bevorzugter Ausführungsform ist die Stanz- und/oder Rilllinie in Form eines Bandstahlschnitts ausgebildet und auf der der Stanz- oder Rilllinienkante gegenüberliegenden Seite ist mindestens eine erste Ausschneidung zur Aufnahme des Stegs des elastischen Halteelementes ausgebildet. Hierdurch wird vermieden, dass das Material des Halteelementes im Bereich des Stegs durch die Stanz- und/oder Rilllinie beschädigt oder im ungünstigsten Fall durchtrennt wird.In a preferred embodiment, the punching and/or creasing line is designed in the form of a strip steel cut and on the side opposite the punching or creasing line edge there is at least one first cut-out for receiving of the web of the elastic holding element. This avoids the material of the holding element being damaged in the region of the web by the punching and/or scoring line or, in the worst case, being severed.

Darüber hinaus weist die Stanz- und/oder Rilllinie auf der der Stanz- oder Rilllinienkante gegenüberliegenden Seite mindestens eine zweite Ausschneidung zur Aufnahme einer Brücke der Trägerplatte auf, die zwischen zwei voneinander beabstandeten Ausnehmungen ausgebildet ist. Die hierdurch ausgebildete Brücke der Stanz- und/oder Rilllinie liegt im zusammengesetzten Zustand des Stanz- und Rillwerkzeugs auf der Brücke der Trägerplatte auf, weshalb vermieden wird, dass die Stanz- und/oder Rilllinie beim Stanzen in die Ausnehmungen hineingedrückt wird. Vielmehr ist hierdurch ein konstanter Abstand zwischen der Stanz- oder Rilllinienkante und der Oberfläche der Trägerplatte gewährleistet.In addition, the punching and/or creasing line has at least one second cutout on the side opposite the punching or creasing line edge for receiving a bridge of the carrier plate, which is formed between two recesses spaced apart from one another. In the assembled state of the punching and creasing tool, the bridge of the punching and/or creasing line formed in this way rests on the bridge of the carrier plate, which is why it is avoided that the punching and/or creasing line is pressed into the recesses during punching. Rather, this ensures a constant distance between the punched or creasing line edge and the surface of the carrier plate.

Nach einer besonders bevorzugten Ausführungsform der vorliegenden Erfindung ist vorgesehen, dass die Trägerplatte mehrere Ausnehmungen und/oder Aussparungen zur Aufnahme mehrerer Halterungen sowie mehrerer Stanz- und/oder Rilllinien aufweist, die eine geschlossene Stanz- und Rillkontur bilden. Vorzugsweise sind dabei die Stanzlinien unmittelbar klemmend in den Ausnehmungen der Trägerplatte gehalten und die Rilllinien sind klemmend in den elastischen Halteelementen gelagert. Mithin werden die Stanzlinien in an sich bekannter Weise in die Ausnehmungen der Trägerplatte eingesteckt und werden hierin kraft- bzw. reibschlüssig gehalten. Nur die Rilllinien werden in diesem bevorzugten Ausführungsbeispiel durch ein erfindungsgemäßes Halteelement gehalten.According to a particularly preferred embodiment of the present invention, it is provided that the carrier plate has a number of recesses and/or recesses for accommodating a number of holders and a number of stamping and/or creasing lines which form a closed stamping and creasing contour. Preferably, the punched lines are clamped directly in the recesses of the carrier plate and the scoring lines are clamped in the elastic holding elements. Consequently, the punched lines are inserted into the recesses of the carrier plate in a manner known per se and are held therein with a non-positive or frictional connection. In this preferred exemplary embodiment, only the scoring lines are held by a holding element according to the invention.

Specific embodiments of the present invention are explained below with reference to the figures. Show it:
Fig. 4a-d:
different schematic views of a carrier plate and
Figure 5:
a perspective view of a holding element.

Fig. 4a zeigt einen Ausschnitt einer Trägerplatte 4 mit zwei Ausnehmungen 5, 5' zur Aufnahme einer Stanz- oder Rilllinie in einer Draufsicht. Die Ausnehmungen 5, 5' sind mit zusätzlichen Aussparungen 15, 15' verbunden, die ausgebildet sind, um jeweils ein elastisches Halteelement 16, 16' aufzunehmen, das in die Aussparungen 15, 15' eingeführt werden kann. Die Halteelemente 16, 16' besitzen jeweils eine Nut 17, 17', die im Vergleich zu den Ausnehmungen 5, 5' schmaler ausgestaltet sind. Hierdurch wird die Stanz- und/oder Rilllinie ausschließlich von den elastischen Halteelementen 16, 16' gehalten und ein unmittelbarer Kontakt zwischen der Stanz- und/oder Rilllinie und der Trägerplatte 4 wird - zumindest zur Vermeidung einer Klemmung - verhindert. Figure 4a shows a detail of a carrier plate 4 with two recesses 5, 5 'for receiving a punched or creasing line in a top view. The recesses 5, 5' are connected to additional recesses 15, 15', which are designed to respectively receive an elastic retaining element 16, 16', which can be inserted into the recesses 15, 15'. The holding elements 16, 16' each have a groove 17, 17' which is narrower than the recesses 5, 5'. As a result, the punching and/or creasing line is held exclusively by the elastic holding elements 16, 16' and direct contact between the punching and/or creasing line and the carrier plate 4 is prevented--at least to avoid jamming.

Fig. 4b zeigt den Querschnitt A-A der Trägerplatte 4 mit eingelegter Rilllinie 7 in einem Bereich außerhalb der Aussparung 15, 15'. Im zusammengesetzten Zustand ist zwischen der Rilllinie 7 und der Trägerplatte 4 ein Spalt 18 angeordnet, der eine Zentrierung der Rilllinie 7 erlaubt und der verhindert, dass Klemmkräfte von der Rilllinie 7 auf die Trägerplatte 4 übertragen werden, womit eine unerwünschte Ausdehnung der Trägerplatte 4 vermieden wird. Figure 4b shows the cross section AA of the carrier plate 4 with an inserted scoring line 7 in an area outside the recess 15, 15'. In the assembled state, a gap 18 is arranged between the crease line 7 and the carrier plate 4, which allows the crease line 7 to be centered and which prevents clamping forces from being transmitted from the crease line 7 to the carrier plate 4, thus avoiding an undesired expansion of the carrier plate 4 .

Fig. 4c zeigt den Querschnitt B-B und mithin die klemmende Lagerung der Rilllinie 7 in einem elastischen und im Querschnitt U-förmigen Halteelement 16, das in der Aussparung 15 der Trägerplatte 4 angeordnet ist und dass ein Herausrutschen der Rilllinie 7 vermeidet. Figure 4c shows the cross section BB and thus the clamping mounting of the scoring line 7 in an elastic and cross-sectionally U-shaped holding element 16 which is arranged in the recess 15 of the carrier plate 4 and that prevents the scoring line 7 from slipping out.

Die Längsschnittdarstellung in Fig. 4d zeigt die Seitenansicht der Rilllinie 7, die an der Unterkante 21 zwei Ausschneidungen 19, 19' zur Aufnahme der Stege 20, 20' der U-förmigen Halteelemente 16, 16' aufweist, damit die Stege 20, 20' beim bestimmungsgemäßen Gebrauch des Stanz- und Rillwerkzeugs nicht beschädigt oder durchtrennt werden. In an sich bekannter Weise ist eine weitere Ausschneidung 9 zur Aufnahme der Brücke 6 zwischen den Ausnehmungen 5, 5' der Trägerplatte 4 vorgesehen.The longitudinal section in Figure 4d shows the side view of the scoring line 7, which has two cutouts 19, 19' on the lower edge 21 for receiving the webs 20, 20' of the U-shaped holding elements 16, 16', so that the webs 20, 20' and creasing tool are not damaged or severed. In a manner known per se, a further cutout 9 for receiving the bridge 6 is provided between the recesses 5, 5' of the carrier plate 4.

Schließlich zeigt Fig. 5 eine perspektivische Darstellung eines elastischen Halteelementes 16 mit einem rechteckigen Längsschnitt und einem rechteckigen horizontalen Querschnitt. Im vertikalen Querschnitt ist das Halteelement 16 U-förmig ausgebildet und besitzt eine Steg 20 sowie zwei freie Schenkel 22, 22', zwischen denen die Nut 17 zur klemmenden Lagerung der Stanz- und/oder Rilllinie (in Fig. 5 nicht dargestellt) ausgebildet ist.Finally shows figure 5 a perspective view of an elastic holding element 16 with a rectangular longitudinal section and a rectangular horizontal cross section. In vertical cross section, the holding element 16 is U-shaped and has a web 20 and two free legs 22, 22', between which the groove 17 for clamping the punching and/or creasing line (in figure 5 not shown) is formed.
