Abstract
Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Stanzen eines Fertigstapels flächiger Gebilde, insbesondere von Etiketten, aus einem Grundstapel nach den Merkmalen der Oberbegriffe der Patentansprüche 1 und 5. Derartige Vorrichtung und Verfahren sind aus den Dokument FR-A-2202459 bekannt.The invention relates to a method and a device for punching a finished stack of flat structures, especially of labels, from a basic stack according to the Features of the preambles of claims 1 and 5. Such apparatus and methods are known from document FR-A-2202459.
Beim sogenannten Gegendruck-Durchstossstanzen mit entsprechenden Vorrichtungen, wie sie beispielsweise in DE-A-40 13 071 und WO-A-96/12593 beschrieben sind, wird jeweils ein Fertigstapel flächiger Gebilde, wie z.B. Etiketten, mittels eines als Hohlform ausgebildeten Stanzmessers in einem Hub aus einem Grundstapel flächiger Gebilde herausgestanzt und gleichzeitig in den Hohlraum des Stanzmessers hinein bzw. durch diesen hindurchgedrückt. Um ein Durchbiegen der oberen Blätter des Stapels beim Eindringen der Stanzmesserschneide in den Grundstapel zu verhindern - was zu Ungenauigkeiten mit Stanzabsätzen im Fertigstapel führen würde - wird durch den Hohlraum des Stanzmessers ein Gegendruckstempel hindurchgeführt, der unmittelbar vor und während des Stanzvorganges von Seite des Messers her gegen den durch ein Stanzelement gestützten Stapel drückt. Dadurch werden die flächigen Gebilde in einer bezüglich der Innenkontur der Schneiden des Stanzmessers etwa senkrechten Presshaltung durch das Stanzmesser hindurchgeführt. Die verwendeten Grundstapel haben eine einfache geometrische Form, die möglichst an die Form des auszustanzenden Fertigstapels angenähert und vorzugsweise rechteckig oder quadratisch ist. Sie werden aus Stapeln grosser Bögen zugeschnitten, ehe sie der Stanzvorrichtung zugeführt werden. Aus jedem Grundstapel wird ein Fertigstapel gestanzt. Das Zuschneiden der Grundstapel erfordert eine entsprechende Vorbereitung mit entsprechendem Zeitaufwand und eine passende Schneidemaschine.With the so-called counter-pressure punching with corresponding devices, such as in DE-A-40 13 071 and WO-A-96/12593 are described one finished stack each of flat structures, such as Labels, by means of a hollow form Stamping knife flat in one stroke from a basic stack Formations punched out and at the same time in the cavity of the punch knife into or through this pushed through. To deflect the upper leaves of the stack when the punch knife edge penetrates into the Prevent basic stack - resulting in inaccuracies Would lead to punched paragraphs in the finished stack - will a counter pressure stamp in the cavity of the punching knife carried out immediately before and during the Punching process from the side of the knife against the presses a punch-supported stack. This will the flat structures in one with respect to the inner contour cutting the punch knife approximately vertical Press holding passed through the punch knife. The Basic stacks used have a simple geometric Shape that matches the shape of the die to be punched out Finished stack approximated and preferably rectangular or is square. They become stacks of large sheets cut before they are fed to the punching device become. Every basic stack becomes a finished stack punched. Trimming the basic stacks requires one Appropriate preparation with the appropriate amount of time and a suitable cutting machine.
Aufgabe der vorliegenden Erfindung ist es daher, ein Verfahren und eine Vorrichtung zur Verfügung zu stellen, mit dem bzw. der das Stanzen von Fertigstapeln flächiger Gebilde aus Grundstapeln ohne vorangehendes aufwendiges Vorschneiden der Grundstapel möglich ist.The object of the present invention is therefore a To provide methods and an apparatus with which the punching of finished stacks is more extensive Formations from basic stacks without previous complex Pre-cutting the basic stack is possible.
Die Aufgabe wird gelöst durch ein Verfahren gemäss den Merkmalen des Anspruches 1 und eine Vorrichtung gemäss den Merkmalen des Anspruches 5.The task is solved by a method according to the Features of claim 1 and a device according to the Features of claim 5.
Durch das Vereinen mehrerer aufeinanderfolgender Stanzvorgänge in einem Stanzzyklus, während dem ein langgestreckter, quaderförmiger Grundstapel zwischen den einzelnen Stanzvorgängen in Richtung seiner Längsachse auf ein Stanzmesser zu verschoben und jeweils neu unter dem Stanzmesser ausgerichtet wird, ist es möglich, während des Stanzzyklus' mit dem Stanzmesser mehrere Fertigstapel flächiger Gebilde aus dem einen Grundstapel auszustanzen. Ein Vorschneiden einzelner Grundstapel, aus denen dann jeweils nur ein einziger Fertigstapel ausgestanzt wird, entfällt somit, was eine entsprechende Schneidvorrichtung überflüssig macht und Zeit spart.By combining several consecutive Punching operations in a punching cycle during which a elongated, cuboid basic stack between the individual punching operations in the direction of its longitudinal axis a punch knife moved and new under the Punch knife is aligned, it is possible during the Punching cycle 'with the punching knife several finished stacks to punch out flat structures from the one basic stack. A pre-cutting of individual basic stacks, from which then only one finished batch is punched out at a time, is therefore not necessary what a corresponding cutting device makes unnecessary and saves time.
Ein weiterer Vorteil der Erfindung ist, dass der relativ grosse Ausschuss, d.h. der anfallende, nichtverwertbare Rest, der bisher beim Ausstanzen eines einzigen Fertigstapels aus einem Grundstapel übrig blieb, beträchtlich vermindert wird, da die auszustanzenden flächigen Gebilde sozusagen ineinander verschachtelt im Grundstapel angeordnet sein können. Der Grundstapel wird in optimaler Weise also zwischen den Stanzvorgängen nur um die Länge bzw. Breite eines Fertigstapels verschoben, was eine beträchtliche Materialeinsparung ermöglicht.Another advantage of the invention is that it is relatively large rejects, i.e. the accruing, unusable Rest, so far when punching out a single one Finished stack from a basic stack remained, is considerably reduced since the punched flat structures, so to speak, nested one inside the other Basic stack can be arranged. The basic stack is in an optimal way just between the punching processes the length or width of a finished batch shifted what allows a considerable saving of material.
Vorteilhafter Weise wird der Fertigstapel durch einen Gegendruckstempel in Richtung auf ein als Auflageplatte ausgebildetes Stanzelement aus dem Stanzmesser herausgedrückt und durch eine Aufnahmevorrichtung seitlich aus dem Bereich zwischen Stanzmesser und Auflagetisch entfernt. Dadurch kann gleichzeitig mit dem seitlichen Entfernen des Fertigstapels aus dem Stanzbereich der Grundstapel in Richtung auf das Stanzmesser verschoben und unter diesem ausgerichtet werden, was die Zeit zwischen zwei Stanzvorgängen verkürzt.The finished stack is advantageously replaced by a Counter pressure stamp in the direction of a as a platen formed punching element from the punching knife pushed out and laterally by a cradle from the area between the punching knife and the support table away. This can be done simultaneously with the side Remove the finished stack from the punching area of the Basic stack moved in the direction of the punch knife and be aligned under this what the time between shortened two punching processes.
Eine erfindungsgemässe Vorrichtung gemäss den Merkmalen des Anspruches 4 erlaubt ein Ausstanzen mehrerer Fertigstapel aus einem langgestreckten, quaderförmigen Grundstapel, ohne dass dieser vorgängig in einzelne Grundstapel vorgeschnitten werden müsste. Die durch das Eindringen des Stanzmessers zueinander verschobenen flächigen Gebilde des Grundstapels können mit Hilfe eines als Anschlag dienenden Ausrichteelementes, gegen das der Grundstapel mit Hilfe eines Schiebeelementes verschoben wird, wieder unter dem Stanzmesser ausgerichtet werden.A device according to the invention according to the features of claim 4 allows punching out several Finished stack from an elongated, cuboid Basic stack without first dividing it into individual Basic stack would have to be pre-cut. The through that Penetration of the punch knife shifted to each other flat structures of the basic stack can be created using a serving as a stop aligning element against which the Basic stack shifted with the help of a sliding element will be aligned again under the punch knife.
Bei einer besonders vorteilhaften Ausführungsform ist der Anschlag auswechselbar, so dass bei einem Wechsel des Stanzmessers eine Anschlagfläche des Ausrichteelementes einer neuen Aussenkontur des Stanzmesser angepasst werden kann.In a particularly advantageous embodiment, the Interchangeable stop, so that when changing the Stamping knife a stop surface of the alignment element be adapted to a new outer contour of the punching knife can.
Besonders vorteilhaft ist es, wenn der Abstand zwischen Auflageplatte und Stanzmesser auf mindestens zwei Stapelhöhen einstellbar ist, da so gleichzeitig mit dem Verschieben und Ausrichten des Grundstapels unter dem Stanzmesser seitlich eine Aufnahmeeinrichtung zum Entfernen des Fertigstapels zwischen Stanzmesser und Auflageplatte hin- und herbewegbar ist.It is particularly advantageous if the distance between Platen and punch knife on at least two Stack heights can be adjusted, because at the same time as the Move and align the basic stack under the Punching knife on the side a holder for Remove the finished stack between the punch knife and Platen is movable back and forth.
Weitere Vorteile der Erfindung ergeben sich aus den abhängigen Ansprüchen und aus der nachfolgenden Beschreibung. Dort wird die Erfindung anhand eines in den Zeichnungen schematisch dargestellten Beispiels näher erläutert.Further advantages of the invention result from the dependent claims and from the following Description.

In den Figur 1 und 2 ist eine Etikettenstanzvorrichtung 10
dargestellt, wie sie im wesentlichen aus der WO-A-96/12593
bekannt ist. Sie weist ein Maschinengestell 12 mit einem
Stanzelement 14, einem Stanzmesser 16 und einem
Gegendruckstempel 18 auf, die, wie aus Figur 1
ersichtlich, in einer schiefen Ebene 34 angeordnet sind.
Das Stanzelement 14 ist als Auflageplatte 20 ausgebildet
und bildet einen Teil eines Auflagetisches 22, wie er in
Fig. 2 deutlich erkennbar ist. Auflagetisch 22 und
Auflageplatte 20 sind mittels eines hydraulischen oder
pneumatischen, ersten Betätigungselementes 24 in der Ebene
34 hin- und zurückverschiebbar (Pfeil A) . Der
Gegendruckstempel 18 ist mittels eines hydraulischen oder
pneumatischen Elementes 28 im Hohlraum des Stanzmessers 16
ebenfalls in der Ebene 34 hin- und zurückverschiebbar
(Pfeil B). Er ist dabei derart gestaltet, dass seine
Aussenkonturen mit geringem Abstand an den Innenkonturen
des Stanzmessers entlanggleiten. Gegendruckstempel 18 und
Stanzmesser 16 sind auf einem Schlitten 30 befestigt, der
auf einem Ausleger 32 am Maschinengestell 12 mittels eines
zweiten, hier nicht dargestellten, hydraulischen oder
pneumatischen Betätigungselementes parallel zur Ebene 34
hin- und zurückbewegbar (Pfeil C) ist. Der Schlitten 30
ist mittels einer mechanischen Arretierung (hier nicht
dargestellt) für den eigentlichen Stanzvorgang fixierbar.1 and 2 is a
Mit einer Seite durch eine zur Ebene 34 parallelen
Auflagefläche 13 abgestützt liegt ein langgestreckter,
quaderförmiger Grundstapel 26 aus einer Vielzahl von
flächigen Gebilden 54, wie Blättern aus Papier, dünnem
Halbkarton oder dergleichen auf dem Auflagetisch 22. Mit
Hilfe eines Niederhalters 36 ist der Grundstapel 26 im
Stanzbereich 38 zwischen Stanzmesser 16 und Auflageplatte
14/20 parallel zur Auflagefläche 13 ausgerichtet und
gehalten. Zum Ausrichten des Grundstapels 26 in Richtung
seiner Längsachse 40 ist im ersten, die Auflageplatte
14/20 aufweisenden Endbereich 42 des Auflagetisches 22 ein
Ausrichteelement 44 angeordnet. Im gegenüberliegenden
zweiten Endbereich 46 des Auflagetisches 22 ist ein
Schiebeelement 50 vorgesehen. Das Ausrichteelement 44
weist eine gegen den zweiten Endbereich 46 des
Auflagetisches 22 gerichtete Anschlagfläche 48/48' auf,
gegen die der Grundstapel 26 mit Hilfe des
Schiebeelementes 50 geschoben wird.With one side through one parallel to
In Fig. 3 ist ein Grundstapel 26 mit Vielzahl von
auszustanzenden Fertigstapeln 52 dargestellt. Die Form der
Fertigstapel 52, d.h. der auszustanzenden flächigen
Gebilde, vorzugsweise Etiketten, ist in ihrer
Längsausdehnung quer zum Grundstapel 26 angeordnet, wie
dies aus Fig. 2 erkennbar ist. Die Fertigstapel 52 sind
derart ineinander verschachtelt, dass der Grundstapel 26
zwischen den einzelnen Stanzvorgängen eines Stanzzyklus' - während dem die Zahl aller aus einem Grundstapel 26
ausstanzbaren Fertigstapel 52 aus diesem ausgestanzt wird
- jeweils nur um die Breite eines Fertigstapels 52 in
Richtung auf das Stanzmesser 16 verschoben wird. Die
Ausrichtung des Stanzmessers 16 zum Grundstapel 26 bleibt
während des gesamten Stanzzyklus unverändert, d.h. das
Stanzmesser 16 muss nicht gedreht oder parallel zum
Grundstapel 26 und zum Auflagetisch 22 verschoben werden.
Ausserdem ist die Breite des Grundstapels 26 etwa gleich
der Längsausdehnung der Form der Fertigstapel 52, so dass
der nach einem Stanzzyklus verbleibende Abfall minimal
ist.3 is a
Anhand der Fig. 4 bis 13 werden nun die einzelnen Schritte
des Verfahrens genauer beschrieben. Dabei sind von der
Vorrichtung 10 jeweils nur die für den jeweiligen Vorgang
wesentlichen Elemente dargestellt.4 to 13, the individual steps are now
of the method described in more detail. Here are from
Die Fig. 4 bis 7 zeigen einen frisch in die Vorrichtung 10
eingebrachten, langgestreckten, quaderförmigen Grundstapel
26 mit einer Vielzahl von Fertigstapeln 52, deren Form
durch die Form der auszustanzenden flächigen Gebilde
(Etiketten) bestimmt ist. Dieser Grundstapel 26 wird
zunächst, vgl. hierzu Fig. 4 und 5, vom Schiebeelement 50
gegen einen rechtwinklig zum Auflagetisch 22 und zur
Auflagefläche 13 des Maschinengestells 12 ausgerichteten
Teil der Anschlagfläche 48' des Ausrichteelementes 44
geschoben und von einem Niederhalter 36 bezüglich der
nichtdargestellten Auflagefläche 13 des Maschinengestelles
12 ausgerichtet und gehalten.4 to 7 show a fresh in the device 10th

Vor dem Ausstanzen des Fertigstapels 52 wird der
Gegendruckstempel 18 gegen den von der Auflageplatte 20
gestützten Grundstapel 26 gedrückt, was hier nicht
dargestellt ist, und das Schiebeelement 50 sowie das
Ausrichteelement 44 und vorteilhafterweise auch der
Niederhalter 36 werden vom Grundstapel 26 zurückgezogen
(vgl. Fig. 6 und 7). Dadurch sind zwar die den Grundstapel
26 bildenden flächigen Gebilde 54 frei gegeneinander
verschiebbar, sie können sich aber nicht in Richtung des
Stanzmessers 16 aufwölben. Die als Stanzelement 14
dienende Auflageplatte 20, welche den ersten zu stanzenden
Fertigstapel 52' stützt, sowie der weitere Teil des
Auflagetisches 22 (jeweils nicht dargestellt) werden gegen
das Stanzmesser 16 und gegen den Gegendruckstempel 18
verschoben (siehe auch Fig. 7), so dass der erste
Fertigstapel 52 aus dem Grundstapel 26 gestanzt wird, wie
dies in den Fig. 6 und 7 dargestellt ist.Before the
Bedingt durch die konische Aussenform seiner Schneide 58
verschiebt das Stanzmesser 16 beim Eindringen in den
Grundstapel 26 die einzelnen flächigen Gebilde 54 des
Grundstapels 26 gegeneinander, was in einer schrägen
Stirnfläche 56 des verbleibenden Grundstapels 26
resultiert, wie dies in den Fig. 8 bis 10 dargestellt ist.Due to the conical shape of its
Der Auflagetisch 22 mit der Auflageplatte 14/20 wird nach
dem Stanzen des Fertigstapels 52 in seine Ausgangsposition
zurückbewegt, so dass sich der Grundstapel wieder auf der
Höhe des Ausrichteelementes 44 und des Schiebeelementes 50
befindet, wie dies in den Fig. 8 bis 10 gezeigt ist. The support table 22 with the support plate 14/20 is after
punching the
Das anschliessende Herausdrücken des Fertigstapels 52 aus
dem Stanzmesser 16 und das seitliche Entfernen des
Fertigstapels 52 aus dem Stanzbereich 38 ist in WO-A-96/12593
beschrieben. Der Abstand d zwischen Auflageplatte
20 und Stanzmesser 16 beträgt dabei mindestens zwei
Stapelhöhen h des Grundstapels 26. Gleichzeitig mit diesem
Vorgang wird der Grundstapel 26 mit der schrägen
Stirnfläche 56, die die Aussenkontur des Stanzmessers
wiedergibt, mit Hilfe des Schiebeelementes 50 gegen die
Anschlagfläche 48' des Ausrichteelementes 44 geschoben,

dienenden Auflageplatte 20, dem Niederhalter 36, dem
Schiebeelement 50 und dem Ausrichteelement 44 sowie das
mit dieser Vorrichtung 10 ausführbare Verfahren können
natürlich nicht nur mit einer Ettikettenstanzvorrichtung
wie sie hier und in der WO-A- 96/12593 beschrieben ist,
kombiniert und durchgeführt werden. Geeignet wäre auch
