Description

Die Erfindung betrifft ein Stanz- und Rillwerkzeug zur Herstellung von gerillten Stanzteilen nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a punching and creasing tool for production of grooved stamped parts according to the generic term of 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.Cardboard box blanks are usually received Creases, through which the folding boxes during later erection maintain their defined shape. The contours as well as necessary Incisions in the folding box blank are made by Punching generated. The production takes place by means of steel strip - stamping and Creasing tools on flat bed or rotary punches.

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 exist from a carrier plate made of wood, for example, connected Plastics with glass fabric or in sandwich construction Armored metal plates. In this carrier plates are made accordingly slots are introduced into the box contours that correspond to those Punching or creasing lines are included. The punch lines are either exactly as far or further from the carrier plate like the crease lines. The punch lines work against one 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 for example in the patents DE 39 28 916 C1 or DE 38 31 393 A1 shown.

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 crease lines create a crease in the folding box material by pushing the material into a groove. This Grooved grooves can be milled into the punching plate or as a structure be attached to the punching plate. The folding box material should be along the creases exactly and with a defined Folding resistance to be foldable. The folding process comes in particular of particular importance in cartoning machines because of the exactness and folding behavior of the creases the achievable Working speed of the cartoning machine depends.

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 with the generation of exact crease lines arise with the well-known steel stamping and creasing tools from the Interaction of crease lines and crease groove. The creasing line is Part of the carrier plate while the creases on the Punching-grooved plate are attached. The slots for inclusion the crease lines are e.g. with laser NC controlled in the Carrier plate introduced. With the same program Creasing grooves NC-controlled incorporated into the punching-creasing plate. When aligning the backing plate to the punch-crease plate it still does not prevent the crease lines in the Carrier plate not exactly in the middle of the corresponding one Rillnut are placed. This is inevitable because the Creases in the slots of the carrier plate due to the clamp fit being held. This results in a large number of parallel creasing lateral tension, the result in minor transfers. The crease lines must therefore be partially hand-adjusted or the groove widths must be adjusted accordingly. This is however unfavorable, since the smallest possible crease is desired is to achieve a precise and symmetrical folding edge.

Aus der FR-A-2 315 368, die als der nächstliegender Stand der Technik angesehen wird, ist ein Stanz- und Rillwerkzeug zur Herstellung von gerillten Stanzteilen aus einem Materialbogen bekannt, das eine Trägerplatte aufweist, an deren Unterseite Stanzelemente vorgesehen sind. Zwischen den Stanzelementen ist eine Rillungsplatte angebracht, an deren Unterseite Rillvorsprünge ausgebildet sind. Zwischen der Trägerplatte und der Rillungsplatte ist ein elastisches Material vorgesehen, wodurch die Rillungsplatte gleichzeitig eine Auswerferfunktion erfüllen kann, um gestanzte Bogen abzustreifen. Unter der Trägerplatte ist eine Stanz-Rillplatte vorgesehen, in der unterhalb der Rillvorsprünge Rillnuten ausgebildet. Eine exakte ebene Ausrichtung der Rillungsplatte bezüglich der Stanz-Rillplatte ist aufgrund ihrer elastischen Lagerung nicht möglich.FR-A-2 315 368, which is considered to be the closest prior art, discloses a punching and creasing tool Production of grooved stamped parts from a sheet of material known that has a support plate on the underside Stamping elements are provided. Is between the stamping elements a grooved plate attached to the underside of creasing projections are trained. Between the carrier plate and the Grooved plate is provided by an elastic material, whereby the grooved plate also has an ejector function can meet to strip punched sheets. Under the A punching and scoring plate is provided in the carrier plate Grooved grooves are formed below the creasing projections. A exact level alignment of the grooved plate with respect to the Punching-grooved plate is not due to its elastic storage possible.

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. Then, as shown in Fig. 2, the carrier plate 21 on the grooved plate 16 or on several grooved plates (with multiple uses). In the carrier plate 21 are 16 holes in the area above the grooved plate provided in which leveling bushes 34 by means of a clamp fit are attached, the lower end faces of which lie in one plane and to a small extent from the underside of the carrier plate 21 protrude.

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 holes 24 are provided in the carrier plate 21, the one with second centering openings 26 in the punch-crease plate 10 align and have the same diameter as this. The Carrier plate 21 is by means of dowel pins 28 on the punch-crease plate 10 fixed in each center hole 24 and the engage 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 Trägerplatte 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 which each have a punching line 30 inserted so that you Back is flush with the top of the support plate 21 and the cutting edge 32 facing the stamping-scoring plate 10 is the stamping plate 10 touches when the carrier plate 21 on the grooved plate 16 rests. Between the grooved plate 16 and the Carrier plate 21, a double-sided adhesive tape (not shown) is arranged, with which the grooved plate 16 provisionally on the End faces of the leveling bushings 34 in the carrier plate 21 is fixed.

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 is attached the grooved plate 16 attached to it from the punched grooved plate 10 lifted off, and there are the dowel pins 20 and 28th away. Now the adhesive tape is used to temporarily Carrier plate 21 fixed grooved plate 16 by Screws (not shown) connected to the carrier plate 21, through the through openings 36 of the leveling bushings 34 go through and engage in threaded bores 38, the the top of the grooved plate 16 are provided.

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 in this way several scoring plates 16 in one exact position on the support plate 21 is attached to align the creases 22 with the corresponding ones Groove grooves 12 only a one-time alignment of the carrier plate 21 required connected to a pressure plate becomes.

Die Nivellierungsbuchsen 34 dienen zur Schaffung einer präzisen Auflageebene, da die Trägerplatte 21 an ihrer Unterseite Unebenheiten aufweisen kann.The leveling bushings 34 serve to create a precise Support level, since the carrier plate 21 on its underside Can have bumps.
