Abstract

In the method for production of scored punched parts from a material sheet by a punching and scoring tool the formation of scores in the material sheet is started before the punching process is initiated. The punching and scoring tool has a carrier board, on the underside of which punching elements and scoring elements are provided, and a punching/scoring plate under the carrier board, in which scoring grooves are formed under the scoring elements. The scoring elements in an initial position, in which the scoring elements and punching elements are arranged at a distance from the punching/scoring plate, project further from the carrier board towards the punching/scoring plate than the punching elements. The scoring elements are also mounted flexibly on the carrier board in the lifting direction.

Description

Die Erfindung betrifft ein Verfahren sowie ein Stanz- und Rillwerkzeug zur Herstellung von gerillten Stanzteilen nach den Oberbegriffen der Patentansprüche 1 bzw. 2.The invention relates to a method and a punching and Creasing tool for the production of grooved stamped parts the preambles of claims 1 and 2 respectively.

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 given Creases through which the folding boxes when later erected 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 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, in 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. Die Rillinien erzeugen einen Rillwulst 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. Es werden auf diese Weise mit einem Stanzhub die Rillungen und die Stanzkonturen erzeugt, wobei die Rillungen erst dann geformt werden, wenn die Stanzlinien den Stanzvorgang begonnen haben. Solche Werkzeuge sind beispielsweise in den Patentschriften DE 39 28 916 Cl oder DE 38 31 393 A1 dargestellt.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 in the box contours, in which 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. Create the crease lines a crease in the folding box material in that they Press material into a creasing groove. These creases can be in the punching plate is milled or as a structure on the punching plate to be appropriate. It is done with a punch stroke the creases and the punched contours are produced, the creases only be formed when the punched lines are the Punching process has started. Such tools are for example in the patents DE 39 28 916 Cl or DE 38 31 393 A1 shown.

Der Stanz- und Rillvorgang ist bei den bekannten Stanz- und Rillwerkzeugen problematisch, da das Material durch die Rillinie erst dann in die entsprechende Rillnut eingezogen wird, wenn der Stanzvorgang bereits begonnen hat, d.h. die Stanzlinien bereits in den Karton eingedrungen sind.The punching and creasing process is in the known punching and Creasing tools problematic because the material through the crease line only then is pulled into the corresponding groove, if the punching process has already started, i.e. the punch lines have already entered the box.

Durch das Einziehen des Materials in die Rillnut ist eine Wegverlängerung gegenüber der Rillnutbreite von theoretisch bis ca. 50% erforderlich. Die Rillinie versucht dieses Mehrmaterial seitlich heranzuziehen. Dies ist jedoch nur begrenzt möglich, da die Stanzlinien das Material festhalten. Dieser Vorgang wird umso problematischer, je enger parallel verlaufende Stanz- und Rillinien angeordnet sind. Setzen die Stanzlinien auf das Material auf, wird das Material fixiert, dabei zieht die Messerschneide bis zur endgültigen Durchtrennung des Materials ihrerseits in der Kompressionsphase Material ein, so daß der Materialzufluß für die Bildung der Rillwulst stark behindert wird. Da nicht genügend Material nachfließen kann, treten an den Schnittstellen Zugspannungen auf, weil die Rillinien ihrerseits versuchen, Material heranzuziehen, während die Rillinien in die Rillnut eintauchen. Die Zugspannungen im Material bewirken so, daß der Trennvorgang zu einem Schneid-Reißvorgang wird, was die Schnittgüte negativ beeinträchtigt. Die Rillwulst unterliegt ihrerseits Zugspannungen, die durch die benachbarten Schneidlinien verursacht sind. Da nur in Ausnahmefällen Stanz-und Rillinien symmetrisch in einem Faltschachtelzuschnitt angeordnet sind, sind die auf die Rillwulst wirkenden Zugspannungen in der Regel assymetrisch, was zur Assymetrie bzw. Schieflage der Rillwulst in Abhängigkeit vom Abstand der benachbarten Linien führt und das Faltverhalten stark beeinträchtigt. Die Grenzen der Stanz-Rillbarkeit sind dadurch in Abhängigkeit vom Stanzgut und der Faltschachtel-Geometrie vorgezeichnet. Insbesondere die Güte der Rillwulst ist für die nachfolgenden Faltvorgänge in schnelllaufenden Faltschachtelklebe- und Abpackmaschinen von entscheidender Bedeutung.By pulling the material into the groove, there is one Path extension compared to the groove width from theoretical up to approx. 50% required. The creasing line tries this extra material pull sideways. However, this is only limited possible because the punching lines hold the material. This Process becomes more problematic the closer it runs parallel Punching and creasing lines are arranged. Put the punch lines on the material, the material is fixed, thereby pulls the knife edge until the final cut of the Material in turn in the compression phase that the material inflow strong for the formation of the crease is hindered. Since not enough material can flow in, tensile stresses occur at the interfaces because the Creases in turn try to pull material while Dip the crease lines into the crease groove. The tensile stresses in the material so that the separation process into one The cutting-tearing process becomes, which adversely affects the cutting quality. The crease bead is itself subject to tensile stress, caused by the neighboring cutting lines. There only in exceptional cases punching and creasing lines symmetrical in one Folding box cut are arranged on the Creasing tensile stresses usually asymmetrical, what depending on the asymmetry or skew of the creasing bead leads from the distance of the neighboring lines and the folding behavior severely impaired. The limits of punching and scoring are therefore dependent on the punched material and the Folded box geometry. In particular the goodness the crease bead is in for the subsequent folding processes high speed folding carton gluing and packaging machines from vitally important.

Aus der DE 25 46 082 A1 ist ein Stanz- und Rillwerkzeug zur Herstellung von gerillten Stanzteilen aus einem Materialbogen bekannt, das eine Trägerplatte aufweist, an deren Unterseite Stanzelemente und eine Rillungsplatte mit Rillvorsprüngen vorgesehen sind. Unter der Trägerplatte ist eine Stanz-Rillplatte vorgesehen, in der unterhalb der Rillvorsprünge Rillnuten ausgebildet sind. Die Stanz-Rillplatte ist relativ zur Trägerplatte in einer Hubbewegung bewegbar ist, wodurch der Materialbogen in die Rillnuten bewegt wird. Die Rillvorsprünge stehen in einer Ausgangsstellung, in der die Rillelemente und die Stanzelemente im Abstand zur Stanz-Rillplatte angeordnet sind, weiter von der Trägerplatte zur Stanz-Rillplatte hin vor als die Stanzelemente. Die Rillungsplatte ist in Hubrichtung mittels einer elastischen Einrichtung an der Trägerplatte gelagert. Die Rückstellkraft des elastischen Materials ist so gewählt, dass eine Auswerferfunktion gewährleistet ist, d.h. dass das gestanzte Bogenmaterial von den Stanzmessern abgestreift wird, wenn die Trägerplatte in ihre Ausgangsstellung zurückbewegt wird. Dieses Dokument ist als Beschreibung des nächstliegenden Stands der Technik in Betracht zu ziehen.DE 25 46 082 A1 discloses a punching and creasing tool for Production of grooved stamped parts from a sheet of material known, which has a support plate on the underside Punching elements and a scoring plate with scoring projections are provided are. There is a punched and scored plate under the carrier plate provided in the grooves below the creasing projections are trained. The punch-crease plate is relative to the carrier plate is movable in one stroke, whereby the sheet of material is moved into the creasing grooves. The creases are in a starting position in which the creasing elements and the punching elements are arranged at a distance from the punching-crease plate are further from the carrier plate to the punched-grooved plate than the stamping elements. The grooved plate is in the stroke direction by means of an elastic device on the carrier plate stored. The restoring force of the elastic material is like this chosen that an ejector function is guaranteed, i.e. that the punched sheet material is stripped from the punching knives when the carrier plate is in its initial position is moved back. This document is a description of the to consider the closest prior art.

Aus der NL-A-9 002 692 ist ein Verfahren zur Herstellung von gerillten Stanzteilen aus Wellpappe bekannt, bei dem ein Stanz-und Rillwerkzeug verwendet wird, an dem Rill- und Stanzeinrichtungen vorgesehen sind, die zur Ausbildung von Rillungen in der Wellpappe bzw. zum Stanzen der Wellpappe in einer Hubbewegung relativ zu einer Gegenstanzplatte bewegbar sind. Bei der Ausbildung der Rillungen wird mit der Ausbildung von Rillungen in dem Kartonbogen begonnen, bevor der Stanzvorgang eingeleitet wird. Der Stanzvorgang wird eingeleitet, wenn die Ausbildung der Rillungen erfolgt ist. Während des Stanzvorgangs dringen Rilllinien ab einem bestimmten Zeitpunkt nicht weiter in die Wellpappe ein, sondern werden in Richtung der Trägerplatte eingedrückt. Auf diese Weise bleibt die Tiefe der Rillen begrenzt, wenn die Trägerplatte nach unten bewegt wird, bis Stanzlinien mit der Gegenstanzplatte in Berührung kommen.From NL-A-9 002 692 is a process for the production of grooved stamped parts made of corrugated cardboard known in which a Punching and creasing tool is used on the creasing and punching equipment are provided for the formation of creases in the corrugated cardboard or for punching the corrugated cardboard in one Stroke movement are movable relative to a counter-punching plate. In the formation of the creases with the formation of creases started in the cardboard sheet before the punching process is initiated. The punching process is initiated when the Training of the creasing has taken place. During the Stamping process penetrate creasing lines from a certain point in time no further in the corrugated cardboard, but are heading in the direction pressed in the carrier plate. In this way, the depth remains of the grooves is limited when the carrier plate moves down until the punching lines touch the counter-punching plate come.

Bei dem erfindungsgemäßen Verfahren wird der Stanzvorgang eingeleitet, wenn der Materialeinzug in die Rillnuten erfolgt ist. Dadurch werden Spannungen im Material bei der Bildung der Rillinien vermieden, so daß die Rillinien eine hohe Güte aufweisen. Durch die Komprimierung des Materials wir eine genau definierte Faltkante erzeugt, die eine präzise Faltung des Kartonbogens ermöglicht.In the method according to the invention, the punching process initiated when the material is drawn into the creasing grooves is. This creates tension in the material during the formation of the Creasing lines avoided, so that the creasing lines are of high quality exhibit.

Das erfindungsgemäße Verfahren läßt sich am besten mit einem Stanz- und Rillwerkzeug mit den Merkmalen des Patentanpruchs 2 durchführen.The method according to the invention can best be carried out with a Stamping and creasing tool with the features of patent claim 2 carry out.

Bei dem erfindungsgemäßen Stanz- und Rillwerkzeug ist die starre Verbindung von Stanzen und Rillen aufgehoben, so daß es möglich ist, in einem Arbeitshub das Rillen und Stanzen zeitlich verschoben vorzunehmen. Das Material kann spannungsfrei in die Rillnuten eingezogen werden.In the punching and creasing tool according to the invention rigid connection of punches and grooves removed so that it it is possible to time the creasing and punching in one working stroke postponed. The material can be stress-free be drawn into the creasing grooves.

Durch entsprechende Wahl der Rückstellkraft der elastischen Einrichtung kann in Abhähigkeit von der Materialart und Materialstärke des zu rillenden Kartons und der Rillnuttiefe die Komprimierung des Materials im Rillenbereich eingestellt werden.By appropriate selection of the elastic restoring force Furnishing can depend on the material type and material thickness of the boxes to be grooved and the groove depth Compression of the material can be set in the groove area.

Gemäß Anspruch 2 sitzen die Rillelemente elastisch auf dem zu rillenden Material auf, so daß es möglich ist, eine gleichmäßige, konstante Rilltiefe unabhängig von dem Verschleiß der Stanzelemente zu erreichen.Sit according to claim 2 the creasing elements are elastic on the material to be creased on so that it is possible to have an even, constant Creasing depth regardless of the wear of the stamping elements to reach.

Die geometrischen Bedingungen, wie z.B. der Höhenunterschied zwischen Stanzelementen und Rillelementen hängt von der Materialstärke des Stanzgutes und den Rillparametern ab, d.h. der Rillnuttiefe im Verhältnis zur Materialstärke, woraus sich eine Materialkomprimierung ableitet, die für die Ausbildung der Rillwulst von entscheidendem Einfluß ist. Durch den komprimierten Abdruck der Rillelemente wird die Faltkante der Schachtel fixiert. Die Möglichkeit der Komprimierung ist hier erstmalig anwendbar, da Stanz- und Rillelemente voneinander unabhängig arbeiten und der Höhenverschleiß der Stanzelemente im Verlauf der Fertigung sich nicht auf das Höhenverhältnis Stanz-Rillelemente auswirkt, wie das bei dem Stanz-Rillwerkzeugen bisher zwangsläufig der Fall war. Es hat weiter den Vorteil, daß die Rillnuttiefen in der Stanz-Rillplatte mit geringerem Aufwand erstellt werden können. Weiter können die Rillungen schmaler gehalten werden. Dies ist für die Faltkanten der Faltschachteln sehr vorteilhaft. The geometric conditions, e.g. the height difference between stamping elements and creasing elements depends on the material thickness of the punched material and the creasing parameters, i.e. the Groove depth in relation to the material thickness, which results derives a material compression that is necessary for training the creasing bead is of decisive influence. By the compressed Imprint of the creasing elements is the folded edge of the Box fixed. The possibility of compression is here Can be used for the first time since the stamping and creasing elements are mutually exclusive work independently and the height wear of the stamping elements in the course of manufacturing not on the height ratio Stamping-creasing elements affects, as with the stamping-creasing tools was previously the case. It still has that Advantage that the groove depths in the punch-groove plate with can be created with less effort. They can continue Grooves are kept narrower. This is for the folded edges of the folding boxes very beneficial.

Vorzugsweise werden die Rillelemente von Rillvorsprüngen gebildet, die an der Unterseite einer Rillungsplatte vorgesehen sind, die elastisch auf bzw. in der Trägerplatte gelagert ist.The creasing elements are preferably of creasing projections formed, which is provided on the underside of a grooved plate are mounted elastically on or in the carrier plate is.

Die Rillungsplatte ist zweckmäßigerweise mittels einer Elastomerplatte an der Trägerplatte gelagert, die zwischen der Rillungsplatte und der Trägerplatte angeordnet ist.The grooved plate is expediently by means of an elastomer plate mounted on the support plate, which between the Grooved plate and the support plate is arranged.

Zur maßgenauen Fixierung kann die Rillungsplatte in Hubrichtung durch Zentrierbolzen geführt werden, die an der Trägerplatte befestigt sind.The grooved plate can be adjusted in the stroke direction for precise fixation are guided by centering bolts on the carrier plate are attached.

Wenn pro Nutzen eine Rillungsplatte vorgesehen ist, hängt die maßgenaue Plazierung nur von der Herstellung und Zuordnung zur Rillnut der einzelnen Rillungsplatten ab. Damit ist ein bedeutender Vorteil verbunden. Die Rillnuten werden in die Stanz-Rill-Platten NC-gesteuert mit demselben Programm wie die Schlitze für die Stanz-Rillinien in die Trägerplatte eingebracht. Aber durch das Eintreiben der Linien in die Schlitze entstehen Verspannungen, die zu Maßabweichungen der Rillinien in der Trägerplatte und den Rillnuten in der Stanz-Rill-Platte führen, so daß die Rillinien per Hand, also sehr kostspielig, nachgerichtet werden müssen. Diese Fehlerquelle ist mit dem neuen Verfahren über die eigene Rillungsplatte beseitigt.If a scoring plate is provided for each panel, it depends accurate placement only from manufacture and assignment to Creasing of the individual creasing plates. So that's a significant one Advantage connected. The creasing grooves are in the punch-creasing plates NC controlled with the same program as that Slots for the punch-crease lines are made in the carrier plate. But by driving the lines into the slots tensions arise that lead to dimensional deviations of the crease lines in the carrier plate and the creasing grooves in the punch-creasing plate lead, so that the crease lines by hand, so very expensive, must be notified. This source of error is with the new procedures via the own grooved plate eliminated.

Die Rillungsplatte kann neben der Rillungsfunktion auch die Funktion einer Niederhalterplatte und Abstreifplatte übernehmen.In addition to the creasing function, the creasing plate can also be used Take over the function of a hold-down plate and scraper plate.

Das in Fig.1 und 2 gezeigte Stanz- und Rillwerkzeug 1 ist zwischen einer Druckplatte 3 und einer Gegendruckplatte 4 einer Stanzmaschine angeordnet. Das Stanz- und Rillwerkzeug 1 weist eine horizontal in der Stanzmaschine angeordnete, mit der Druckplatte 3 verbundene Trägerplatte 6, die beispielsweise aus Holzlaminat besteht, und eine mit der Gegendruckplatte 4 verbundene Stanz-Rillplatte 7 aus Stahl auf, die im Abstand unterhalb der Trägerplatte 6 angeordnet ist.The punching and creasing tool 1 shown in FIGS. 1 and 2 is between a pressure plate 3 and a counter pressure plate 4 arranged a punching machine. The punching and creasing tool 1 has a horizontally arranged in the punching machine the pressure plate 3 connected carrier plate 6, for example consists of wood laminate, and one with the counter pressure plate 4 connected punch-crease plate 7 made of steel, which in Distance below the support plate 6 is arranged.

In der Trägerplatte 6 sind vertikale Schlitze ausgebildet, in denen Stanzmesser 2a und 2b aus Bandstahl aufgenommen sind.Vertical slots are formed in the carrier plate 6, in which punch knives 2a and 2b are made of steel strip.

Zwischen den Stanzmessern 2a, 2b ist an der Unterseite der Trägerplatte 6 für jeden Nutzen eine Elastomerplatte 11 vorgesehen, an deren Unterseite eine massive Rillungsplatte 9 anliegt. Die Rillungsplatte 9 ist an ihrer der Stanz-Rillplatte 7 zugewandten Unterseite mit rillgebenden Rillvorsprüngen (Rillelemente) 10a und 10b versehen. Die freien Enden der Rillvorsprünge 10a, 10b erstrecken sich in der in Fig. 1 gezeigten Ausgangsstellung weiter von der Trägerplatte 6 nach unten als die freien Enden der Stanzmesser 2a, 2b, d.h. ihr Abstand zur Stanz-Rillplatte 7 ist geringer als der der Stanzmesser 2a, 2b. Between the punching knives 2a, 2b is at the bottom of the Carrier plate 6 provided an elastomer plate 11 for each use, on the underside there is a massive grooved plate 9 is applied. The grooved plate 9 is on the punched-grooved plate 7 facing underside with creasing protrusions (Creasing elements) 10a and 10b provided. The free ends of the Creasing projections 10a, 10b extend in the in Fig. 1st shown starting position further from the carrier plate 6 to below as the free ends of the punch knives 2a, 2b, i.e. their Distance to the punching-grooving plate 7 is less than that of the punching knife 2a, 2b.

Die Rillungsplatte 9 kann aus Metall, Kunstoff oder Verbundstoff bestehen. Die Rillvorsprünge 10a, 10b können durch Herausfräsen, Herausätzen, durch Einsetzen von Leisten oder Platten in die Rillungsplatte 9 gebildet werden. Die Rillungsplatte 9 schafft den Vorteil, daß eine maßgenaue Plazierung der einzelnen Rillelemente 10a, 10b nicht von der Trägerplatte 6, sondern durch die Herstellung der Rillungsplatte 9 bestimmt wird.The grooved plate 9 can be made of metal, plastic or composite consist. The creasing projections 10a, 10b can be milled out, Etch out by inserting strips or Plates are formed in the grooved plate 9. The crease plate 9 creates the advantage that a precise placement of the individual creasing elements 10a, 10b not from the carrier plate 6, but determined by the manufacture of the grooved plate 9 becomes.

In der Stanz-Rillplatte 7 sind den Rillvorsprüngen 10a, 10b gegenüberliegende Rillnuten 8a und 8b ausgebildet, in die die Rillvorsprünge 10a und 10b Faltschachtelmaterial beim Stanz-Rillvorgang eindrücken.In the punching-creasing plate 7 are the creasing projections 10a, 10b opposite grooves 8a and 8b formed, in which the Creasing projections 10a and 10b folding box material during the punching-creasing process Push.

Die Rillungsplatte 9 ist mit Zentrierbohrungen 13 versehen, in denen jeweils ein Zentrierbolzen 14 verschieblich geführt ist, der durch die Elastomerplatte 11 hindurchgeht und in eine Bohrung 12 der Trägerplatte 6 eingesetzt ist. Die Zentrierbolzen 14 sorgen für eine exakte Zentrierung der Rillvorsprünge 10a, 10b der Rillungsplatte 9 bezüglich der entsprechenden Rillnuten 8a bzw. 8b, so daß eine bestmögliche symmetrische Zuordnung der Rillvorsprünge 10a, 10b und Rillnuten 8a, 8b erreicht wird.The grooved plate 9 is provided with center holes 13 in each of which a centering pin 14 is slidably guided, which passes through the elastomer plate 11 and into a Bore 12 of the support plate 6 is inserted. The centering bolts 14 ensure exact centering of the creasing projections 10a, 10b of the grooved plate 9 with respect to the corresponding one Creasing grooves 8a and 8b, so that the best possible symmetrical Assignment of the creasing projections 10a, 10b and creasing grooves 8a, 8b is achieved.

Zur maßgenauen Fixierung der Rillungsplatte 9 bei der Einrichtung des Stanz- und Rillwerkzeugs 1 sind in der Stanz-Rillplatte 7 Zentrierbohrungen 15 vorgesehen, in die Zentrierstifte bei der Fixierung eingreifen.For precise fixing of the grooved plate 9 during the installation of the punching and creasing tool 1 are in the punching-creasing plate 7 center holes 15 are provided in the centering pins intervene in the fixation.

Nach der maßgenauen Fixierung auf der Stanz-Rillplatte 7 werden die entsprechenden Zentrierbohrungen 12 in der Trägerplatte 6 vorgesehen und die Rillungsplatte 9 mittels der Zentrierstifte 14 auf der Trägerplatte 6 fixiert. After the dimensionally accurate fixation on the punch-crease plate 7 the corresponding center holes 12 in the carrier plate 6 provided and the grooved plate 9 by means of Centering pins 14 fixed on the carrier plate 6.

In der in Fig. 1 gezeigten Ausgangsstellung des Stanz- und Rillwerkzeugs 1 stehen die Rillvorsprünge 10a, 10b um den Betrag A (z.B 0,3 mm) weiter von der Trägerplatte 6 vor als die Stanzmesser 2a, 2b. Der Abstand der Rillvorsprünge 10a, 10b von der Stanz-Rillplatte 7 ist ausreichend um einen Kartonbogen 5 (Fig. 2) zwischen die Rillungsplatte 9 und die Stanz-Rillplatte 7 einzuführen.In the starting position shown in Fig. 1 of the punching and Creasing tool 1 are the creasing projections 10a, 10b around Amount A (e.g. 0.3 mm) further from the carrier plate 6 than the punch knives 2a, 2b. The distance between the creasing projections 10a, 10b from the punch-crease plate 7 is sufficient around a cardboard sheet 5 (Fig. 2) between the grooved plate 9 and the Insert the punch-crease plate 7.

Nach Einführung des Kartonbogens 5 wird die Stanzmaschine geschlossen, wobei sich die Druckplatte 3 mit der Trägerplatte 6 in Richtung der Stanz-Rillplatte 7 bewegt, bis die in Fig. 2 gezeigte Endstellung erreicht wird, in der die Stanzmesser 2a, 2b den Karton durchtrennt und die Rillvorsprünge 10a, 10b Rillen geprägt haben.After the introduction of the cardboard sheet 5, the punching machine closed, the pressure plate 3 with the support plate 6 moved in the direction of the punching-grooving plate 7 until the in Fig. 2nd shown end position is reached, in which the punch knife 2a, 2b severed the cardboard and the creasing projections 10a, 10b Have shaped grooves.

In Fig.3 ist in einem Zeit-Weg-Diagramm der Abstand der Rillvorsprünge 10a, 10b und der Stanzmesser 2a, 2b während des Stanz-Rill-Vorgang mit dem erfindungsgemäßen Stanz- und Rillwerkzeug 1 dargestellt.3 shows the distance between the creasing projections in a time-path diagram 10a, 10b and the punch knife 2a, 2b during the Stamping-creasing process with the stamping and creasing tool according to the invention 1 shown.

Zum Zeitpunkt t0, an dem die Rillvorsprünge 10a, 10b auf den Karton auftreffen, befinden sich die Rillvorsprünge 10a, 10b auf der Höhe RO. Die freien Enden der Stanzmesser 2a, 2b befinden sich zu diesem Zeitpunkt um den Abstand A (Fig. 1) oberhalb der Höhe RO der Kartonoberfläche auf der Höhe S0.At the point in time t 0 at which the creasing projections 10a, 10b hit the cardboard, the creasing projections 10a, 10b are at the height RO. The free ends of the punching knives 2a, 2b are at this time by the distance A (FIG. 1) above the height RO of the cardboard surface at the height S0.

Bis zu dem Zeitpunkt tm, an dem die Stanzmesser 2a, 2b auf die Kartonoberfläche (Höhe RO) auftreffen, ist der Abstand A zwischen den freien Enden der Stanzmesser 2a, 2b und den freien Enden der Rillvorsprünge 10a, 10b konstant, d.h. die Stanzmesser 2a, 2b und die Rillvorsprünge 10a, 10b werden synchron bewegt. Die Rillvorsprünge 10a, 10b haben zum Zeitpunkt tm den Karton in die Rillnuten 8a, 8b eingezogen. Der von dem Karton bei diesem Einziehen entgegengesetzte Widerstand ist bis zum Zeitpunkt tm kleiner als die Rückstellkraft der Elastomerplatte 11.Until the time t m at which the punching knives 2a, 2b hit the cardboard surface (height RO), the distance A between the free ends of the punching knives 2a, 2b and the free ends of the creasing projections 10a, 10b is constant, ie the punching knives 2a, 2b and the creasing projections 10a, 10b are moved synchronously. The creasing projections 10a, 10b have drawn the cardboard into the creasing grooves 8a, 8b at the time t m . The resistance of the cardboard during this pulling-in is smaller than the restoring force of the elastomer plate 11 up to the time t m .

Vom Zeitpunkt tm an, an dem die Komprimierung des Kartons in den Rillnuten 8a, 8b beginnt, bewegen sich die Stanzmesser 2a, 2b und die Rillvorsprünge 10a, 10b unterschiedlich, da der den Rillvorsprüngen 10a, 10b entgegengesetzte Widerstand durch die Komprimierung des Kartons in Verbindung mit der Reaktionskraft der Rillnuten 8a, 8b größer wird als die Rückstellkraft der Elastomerplatte 11, so daß die Elastomerplatte 11 komprimiert wird. Die Rillvorsprünge 10a, 10b bewegen sich vom Zeitpunkt tm bis zum Zeitpunkt te, zu dem die Stanzmesser 2a, 2b auf die Stanz-Rillplatte 7 auftreffen (Fig. 2) nur um den Betrag B, während sich die Stanzmesser 2a, 2b linear durch den Karton um den Betrag C hindurchbewegen, der der Dicke des Kartons entspricht.From the time t m at which the compression of the carton in the creasing grooves 8a, 8b begins, the punching knives 2a, 2b and the creasing projections 10a, 10b move differently, since the resistance opposed to the creasing projections 10a, 10b due to the compression of the carton in Connection with the reaction force of the grooved grooves 8a, 8b is greater than the restoring force of the elastomer plate 11, so that the elastomer plate 11 is compressed. The creasing projections 10a, 10b move from the time t m to the time t e , at which the punching knives 2a, 2b hit the punching-creasing plate 7 (FIG. 2) only by the amount B, while the punching knives 2a, 2b are linear move through the box by the amount C that corresponds to the thickness of the box.

Nach dem Zeitpunkt te wird die Druckplatte 3 mit der Trägerplatte 6 wieder in die in Fig. 1 gezeigte Ausgangsstellung zurückbewegt. Der Stanzzyklus ist beendet.After the time t e , the pressure plate 3 with the carrier plate 6 is moved back into the starting position shown in FIG. 1. The punching cycle has ended.

Anstatt der Elastomerplatte 11 können auch andere elastische Einrichtungen, wie z.B Federn, Gummi oder pneumatische Einrichtungen verwendet werden.Instead of the elastomer plate 11, other elastic ones can also be used Devices such as springs, rubber or pneumatic devices be used.

Die Stanz-Rillplatte 7 kann einteilig mit der Gegendruckplatte 4 ausgebildet sein.The punching-creasing plate 7 can be made in one piece with the counter-pressure plate 4 be formed.

Die Rillnuttiefe 17 hängt vom Stanzgut ab.The groove depth 17 depends on the punched material.

Die herkömmliche Stanztechnik arbeitet mit der Stanz-Rill-Platte, bei der die Rillnuten in die Stanzplatte eingebracht werden. Vielfach werden aber auch separat hergestellte Rillnuten den Rillinien zugeordnet auf die Stanzplatte aufgeklebt. Diese Technik ist selbstverständlich auch mit dem neuen Stanz-Rill-Verfahren möglich.The conventional punching technique works with the punch-crease plate, in which the creasing grooves are introduced into the punching plate become. In many cases, however, grooved grooves are also produced separately assigned to the crease lines glued to the punching plate. Of course, this technology is also available with the new punch-creasing process possible.
