Description

Die Erfindung betrifft eine Vorrichtung zum Stanzen gemäß dem Oberbegriff von Anspruch 1 und weiter eine Vorrichtung zum Stanzen gemäß dem Oberbegriff von Anspruch 10.The invention relates to a punching device according to the preamble of claim 1 and further to a punching device according to the preamble of claim 10.

Als Stanzen wird das Schneiden mit in sich geschlossenen geometrischen Zuschnittsformen bezeichnet, die kreisförmig, oval oder mehreckig sowie Phantasieformen aller Art sein können. Auch die in der Druckweiterverarbeitung geübten Praktiken, wie Stanzen mit Locheisen, Eckenabstoßen und Registerstanzen werden zu diesem Bereich gezählt. Die Stanzung erfolgt gegen eine Stanzunterlage oder gegen Stempel, teilweise sind es auch Schervorgänge. Verpackungsmaterialien aus Papier, Karton, Pappe oder Wellpappe werden hauptsächlich im Bogenformat gestanzt. Beim Stanzvorgang können zusätzlich aber auch Rilllinien oder Blindprägungen in den Nutzen eingebracht werden. Dieser komplexe Prozess macht es unabdingbar, die Bogen einzeln zu stanzen. Da es sich bei den Endprodukten um anspruchsvolle Verpackungen hinsichtlich technischer und graphischer Ausführung handelt (etwa Verpackungen für Kosmetik, Zigaretten, Pharmazie, Lebensmittel, etc.), werden besondere Anforderungen nicht nur an die Verpackungsmaterialien selbst gestellt, sondern es sind für optimale Resultate auch Stanzwerkzeuge mit geringsten Toleranzen und äußerst präzise und zuverlässig arbeitende Stanzmaschinen erforderlich. Diesen Ansprüchen wird das Flachbettstanzen am besten gerecht. Dabei werden die gedruckten und auf einer Palette gestapelten Bogen der Stanzmaschine zugeführt. In der Maschine werden in einer Ausrichteinrichtung die zu stanzenden Bogen passgenau ausgerichtet, von einem Greiferwagen übernommen und exakt in der Stanzeinrichtung zwischen einem fest gelagerten Untertisch und einem über einen Kniehebel oder Exzentergetriebe vertikal bewegbaren Obertisch positioniert.As punching the cutting is referred to with closed geometric blank forms that can be circular, oval or polygonal and imaginary shapes of all kinds. Also the practices practiced in print finishing, such as punching with punch, corner punching and register punching are counted to this area. The punching takes place against a punching pad or against stamp, in some cases it is also shearing operations. Packaging materials made of paper, cardboard, cardboard or corrugated board are mainly punched in sheet format. When punching but also creasing lines or blind embossing can be introduced into the benefit. This complex process makes it indispensable to punch the sheets individually. Since the end products are sophisticated packaging in terms of technical and graphic design (such as packaging for cosmetics, cigarettes, pharmacy, food, etc.), special requirements are not only placed on the packaging materials themselves, but are also punching tools for optimum results required with the smallest tolerances and extremely precise and reliable punching machines. Flatbed punching best meets these demands. The printed sheets stacked on a pallet are fed to the punching machine. In the machine, the sheets to be punched are precisely aligned in an alignment device, taken over by a gripper carriage and positioned exactly in the punching device between a fixed undercounter and a vertical over a knee lever or eccentric upper table.

In bekannten Bogenstanz- und Prägemaschinen, die zum Stanzen, Ausbrechen, Prägen und Ablegen von Bögen aus Papier, Pappe und der gleichen eingesetzt werden, ist es bekannt die Bögen mittels Greiferwagen durch die einzelnen Stationen der Maschine zu bewegen. Ein jeweiliger Greiferwagen besitzt eine Greiferbrücke, an der Greifer befestigt sind, die die Bögen an einem vorderen Ende ergreifen. Ein Greiferwagen besitzt weiterhin seitliche Fahrwagen, welche mit endlosen Ketten des Transportsystems verbunden sind und wodurch die Greiferwagen durch die Maschine bewegt werden. Durch diese Art der Bewegung der Bögen durch die Maschine wird ein kontinuierliches Arbeiten in den einzelnen hintereinander angeordneten Stationen der Maschine, insbesondere Stanz-, Ausbrech- und Nutzentrennstation, ermöglicht.In known sheet punching and embossing machines, which are used for punching, breaking, stamping and depositing sheets of paper, cardboard and the like, it is known to move the sheets by means of gripper carriage through the individual stations of the machine. A respective gripper carriage has a gripper bridge, to which grippers are fixed, which grasp the arches at a front end. A gripper carriage still has lateral Trolleys which are connected to endless chains of the transport system and whereby the gripper carriages are moved through the machine. By this type of movement of the sheets through the machine, a continuous work in the individual successively arranged stations of the machine, in particular punching, break-away and Nutzentrennstation allows.

Eine derartige Flachbettstanze ist beispielsweise aus der DE 30 44 083 A1 bekannt. Die beiden Tische sind mit Schneid- und Rillwerkzeugen bzw. entsprechenden Gegenwerkzeugen bestückt, mit denen aus dem taktweise zwischen die Tischfläche gefiihrten Bögen die Nutzen ausgestanzt und gleichzeitig die zum sauberen Falten notwendigen Rillen eingedrückt werden. In der nachfolgenden Ausbrecheinrichtung wird der Abfall über Ausbrechwerkzeuge maschinell entfernt. Je nach Ausstattung der Maschine können schließlich die gestanzten Nutzen in einer hierfiir vorgesehenen Nutzentrenneinrichtung separiert werden.Such a flat bed punch is for example from the DE 30 44 083 A1 known. The two tables are equipped with cutting and scoring tools or corresponding counter tools with which out of the cyclically guided between the table surface arches punched out the benefits and at the same time pressed the necessary for clean folding grooves. In the subsequent breakout the waste is removed by machine tools. Depending on the equipment of the machine finally the punched benefits can be separated in a provided for this purpose Nutzentrenneinrichtung.

Für ein exaktes und hochwertiges Stanzen ist es notwendig, dass die Schneid- und Rillwerkzeuge relativ zu den Gegenwerkzeugen positioniert werden. Die DE 195 16 073 A1 beschreibt eine Vorrichtung zum Stanzen mit einer oberen positiven Form und einer unteren negativen Form. Die obere Form besteht aus einem Rahmen, in welchem die Stanz- und Rillmesser haltende Tragplatte durch Justier- und Halteschrauben gehalten ist. Die untere Form besteht aus einer Metallplatte, welche das negative Gegenstück zu den Stanz- und Rillmessern bildet. Die Vorrichtung besitzt verstellbare Anschläge, welche dem Positionieren der oberen und / oder unteren Form dienen.For an exact and high-quality punching it is necessary that the cutting and scoring tools are positioned relative to the counter tools. The DE 195 16 073 A1 describes a punching apparatus having an upper positive mold and a lower negative mold. The upper mold consists of a frame in which the punching and Rillmesser holding support plate is held by adjusting and retaining screws. The lower mold consists of a metal plate, which forms the negative counterpart to the punching and Rillmessern. The device has adjustable stops, which serve to position the upper and / or lower mold.

Die EP 0 756 919 B1 beschreibt eine Vorrichtung zum Stanzen mit einem oberen und einem unteren Tiegel. Der eine Tiegel trägt Stanzmesser, der andere Tiegel eine Gegenstanzplatte. Die Gegenstanzplatte umfasst eine fest mit dem Tiegel verbundene Unterplatte und eine ebenfalls dünne Oberplatte. Die Oberplatte ist relativ zur Unterplatte über mindestens ein Führungs- und Antriebselement verstellbar. Mittels mindestens eines Feststellelements sind die beiden Platten relativ zueinander fixierbar.The EP 0 756 919 B1 describes a device for punching with an upper and a lower crucible. The one crucible carries punching knife, the other crucible a counter-punching plate. The counter-punching plate comprises a fixedly connected to the crucible bottom plate and also a thin top plate. The top plate is adjustable relative to the lower plate via at least one guide and drive element. By means of at least one locking element, the two plates are fixed relative to each other.

Die US 5,730,039 beschreibt eine Vorrichtung zur Einstellung der Position einer Stanzplatte in einer Stanzmaschine. Die Vorrichtung umfasst eine Stanzplatte und eine Lagerplatte. Die Lagerplatte ist mit zwei Einstelleinrichtungen, welche jeweils Exzenter umfassen, versehen. Die Stanzplatte verfügt über zwei Ausnehmungen, in welche die Einstelleinrichtungen eingreifen. Durch Verdrehen der Exzenter der Einstelleinrichtungen wird die Stanzplatte relativ zur Lagerplatte verschoben.The US 5,730,039 describes a device for adjusting the position of a punching plate in a punching machine. The device comprises a punching plate and a bearing plate. The bearing plate is provided with two adjusting devices, which each comprise eccentric. The punching plate has two recesses into which the adjusting devices engage. By rotating the eccentric adjusting the punching plate is moved relative to the bearing plate.

Die EP 1 153 716 B9 beschreibt eine Stanzmaschine mit einer Stanzstation, welche ein Stanzblech umfasst. Das Stanzblech liegt auf einer Stützplatte auf und wird durch bewegliche Bügel gehalten. Die beweglichen Bügel besitzen zwei Stellungen: eine erste Klemmstellung, in der das Verschieben des Stanzblechs auf der Stanzplatte verhindert und eine Ruhestellung, in der das Verschieben des Stanzblechs auf der Stützplatte ermöglicht wird. Die Position der Stützplatte relativ zum unteren Tiegel kann über Einstellmittel horizontal verändert werden.The EP 1 153 716 B9 describes a punching machine with a punching station, which comprises a stamped sheet metal. The stamping sheet rests on a support plate and is held by moving stirrups. The movable brackets have two positions: a first clamping position, in which prevents the displacement of the punching plate on the punching plate and a rest position, in which the displacement of the punching plate on the support plate is made possible. The position of the support plate relative to the lower crucible can be changed horizontally via adjusting means.

Aufgabe der vorliegenden Erfindung ist es, eine Vorrichtung zum Stanzen zu schaffen, die eine einfache und exakte Verstellung einer eine Gegenform umfassende Form ermöglicht, wobei die Form nach einem Auftragswechsel wieder einfach in ihre Nullstellung verbringbar ist.Object of the present invention is to provide a device for punching, which allows a simple and exact adjustment of a counter-mold comprehensive form, the mold after a job change is again easy to be brought into their zero position.

Gelöst wird diese Aufgabe durch eine Vorrichtung zum Stanzen mit den kennzeichnenden Merkmalen von Anspruch 1 und durch eine Vorrichtung zum Stanzen mit den kennzeichnenden Merkmalen von Anspruch 10.This object is achieved by a punching device having the characterizing features of claim 1 and by a punching device having the characterizing features of claim 10.

Die erfindungsgemäße Vorrichtung zum Stanzen von bogenförmigem Material aus Papier, Pappe und dergleichen besitzt einen oberen und einen unteren Tiegel. Eine erste positive Form, welche Stanz- und / oder Rillmesser trägt, ist mit dem oberen Tiegel verbunden. Eine zweite negative Form, welche eine Gegenform umfasst, ist mit dem unteren Tiegel verbunden. Die Gegenform ist mit einer Platte verbunden, bevorzugterweise verschraubt, und Gegenform und Platte werden in einem Rahmen gehalten. Dieser Rahmen ist über einen Spannmechanismus mit dem unteren Tiegel verbunden. Über eine Einstelleinrichtung kann der Rahmen zusammen mit der die Gegenform tragenden Platte und der Gegenform relativ zum unteren Tiegel horizontal verstellt werden. Die Verstellung erfolgt bevorzugterweise aktuatorisch bzw. motorisch.The inventive device for punching sheet material of paper, cardboard and the like has an upper and a lower crucible. A first positive mold, which carries punching and / or knives, is connected to the upper crucible. A second negative mold comprising a counter-mold is connected to the lower crucible. The counter-mold is connected to a plate, preferably screwed, and counter-mold and plate are held in a frame. This frame is connected via a clamping mechanism with the lower crucible. About an adjustment of the frame together with the counter-mold carrying plate and the counter-mold are adjusted horizontally relative to the lower crucible. The adjustment is preferably actuator or motor.

In einer bevorzugten Ausführungsform wird die Gegenform durch ein Stanzblech gebildet. In einer bevorzugten Weiterbildung dieser Ausführung wird die die Gegenform tragende Platte durch eine Vakuumplatte gebildet. Das Stanzblech ist mit dieser verschraubt und wird durch ein Vakuum an die Vakuumplatte angepresst. Das Vakuum wird dabei durch einen dem Fachmann bekannten Unterdruckerzeuger erzeugt. Vorteilhafterweise ist die Vakuumplatte wesentlich dicker als das Stanzblech ausgeführt und stellt die tragende Struktur des Stanzblechs dar. Die Vakuumplatte besitzt üblicherweise eine Dicke von ca. 4 bis 10 mm, das Stanzblech eine Dicke von ca. 1 mm.In a preferred embodiment, the counter-mold is formed by a stamped sheet. In a preferred development of this embodiment, the counter-form bearing plate is formed by a vacuum plate. The stamped sheet is bolted to this and is pressed by a vacuum to the vacuum plate. The vacuum is generated by a known to the expert vacuum generator. Advantageously, the vacuum plate is made substantially thicker than the stamped sheet and represents the supporting structure of the punching sheet. The vacuum plate usually has a thickness of about 4 to 10 mm, the stamped sheet has a thickness of about 1 mm.

In einer vorteilhaften Weiterbildung umfasst der Spannmechanismus mindestens zwei Aktoren, welche den Rahmen auf den unteren Tiegel pressen. Die Aktoren können vorteilhaftertweise als Pneumatikzylinder ausgeführt sein. Besonders vorteilhaft ist der Einsatz von vier Pneumatikzylindern, die eine gleichmäßige Anpressung sicherstellen. Alternativ zu den Pneumatikzylindern können auch Hydraulikzylinder oder Elektromoren mit angetriebenen Spindeln zum Einsatz kommen.In an advantageous development, the clamping mechanism comprises at least two actuators which press the frame onto the lower crucible. The actuators can advantageously be designed as pneumatic cylinders. Particularly advantageous is the use of four pneumatic cylinders that ensure uniform contact pressure. As an alternative to the pneumatic cylinders, hydraulic cylinders or electric motors with driven spindles can also be used.

In einer vorteilhaften Weiterbildung der Erfindung verfügt die Einstelleinrichtung über mindestens zwei Aktuatoren zur Verstellung des Rahmens mit Platte und Gegenform in der horizontalen Ebene des Rahmens. In dieser Ebene ist ein zweidimensionales Koordinatensystem aufgespannt. Der erste Aktuator bewirkt eine Verstellung des Rahmens in Richtung der ersten Achse und der zweite Aktuator bewirkt eine Verstellung des Rahmens in Richtung der zweiten Achse des Koordinatensystems. Besonders vorteilhaft ist es, einen Aktuator durch zwei Aktuatoren zu ersetzen, welche jeweils am äußeren Ende des Rahmens angreifen und synchronisiert zueinander angetrieben werden. Dadurch wird sichergestellt, dass der Rahmen parallel zur Achse verschoben wird und keine Drehbewegung ausführt. In dem Fall, dass eine definierte Verdrehung des Rahmens erzielt werden soll, werden die Aktuatoren des Aktuatorpaars nicht synchron, sondern asynchron zueinander betrieben. Als Aktuatoren eignen sich insbesondere steuerbare Elektromotoren.In an advantageous development of the invention, the adjusting device has at least two actuators for adjusting the frame with plate and counter-mold in the horizontal plane of the frame. In this plane, a two-dimensional coordinate system is spanned. The first actuator causes an adjustment of the frame in the direction of the first axis and the second actuator causes an adjustment of the frame in the direction of the second axis of the coordinate system. It is particularly advantageous to replace an actuator by two actuators, which each act on the outer end of the frame and are driven in synchronism with one another. This ensures that the frame is moved parallel to the axis and does not rotate. In the event that a defined rotation of the frame is to be achieved, the actuators of the actuator pair are not synchronized, but operated asynchronously to each other. In particular, controllable electric motors are suitable as actuators.
