Definitions
- the invention relates to an adapter unit according to the preamble of claim 1 for receiving punching tools.
- punching 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.
- 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 punched out of the cyclically guided between the table surface sheets 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 designatedWhentrenn arthritis.
- the DE 102 51 780 A1 describes a sheet punching and embossing machine with a punching device. It is provided a frame for receiving a fitted with punching and knurling knives supporting plate, wherein the support plate, also commonly referred to as a punching tool, can be clamped by means of hydraulically actuated clamping elements. Such a frame is also referred to as a quick-release frame or closing frame. A disadvantage of such a closure frame is that only tools of a certain format, namely the nominal size, can be held by the latter. However, since the production of punching and / or stamping tools is complex and expensive, it is of interest to be able to use tools whose size differs from the nominal format.
- Newer sheet punching and / or embossing machines increasingly have a larger nominal size compared to older machines. For smaller or only occasionally repeating orders, it is not economical to have a reworked to the larger nominal size machining tool. One already existing tools should continue to be used on the new larger format machine.
- the DE 195 16 074 B4 discloses an apparatus for punching with a frame for holding a tool composed of various stamped parts.
- a sliding clamping bar and slidable telescopic rods are arranged in the frame.
- the individual tools are connected via fixing elements.
- a disadvantage of such a device is that results in an uneven punching pressure distribution over the entire crucible surface.
- punching forces can be transmitted only in the area of the frame where individual tools are located.
- the unequal punching pressure distribution results in a high load on the cutting edges as well as a reduced cutting quality.
- the adapter unit according to the invention has a first recess for alternative recording of punching and / or stamping tools of different format in the tool holder of a punching and / or embossing station.
- the stamping and / or embossing tool may comprise a plate element with active elements such as punching knives and / or knives and / or embossing dies.
- the adapter unit has a plurality of telescopic clamping elements for holding the punching and / or embossing tool. Due to the telescoping of the clamping elements is ensured in an advantageous manner that the tool may have different dimensions.
- the adapter unit has at least one further recess in which a plate can be received, which is equipped with force transmission elements.
- the adapter unit corresponds in its external dimensions to the nominal format of the punching and / or embossing station. It is manufactured in particular from a plate-shaped element made of a stiff, kink-resistant and lightweight material, such as aluminum or fiber-reinforced plastic (eg GFK or CFK).
- At least one plate equipped with punching force transmission elements is part of the adapter unit.
- the plate can be designed for example as a wooden plate.
- the force transmission elements are punching blades. Even if no machining of a sheet of paper, cardboard, plastic and the like to be processed in the punching and / or embossing station is desired at the positions of the punching force transmission elements, the use of punching knives represents a cost-effective variant. Thus, the plates equipped with punching knives to be commissioned by the stamping and stamping tool manufacturers. As an alternative to the punching blades, however, it is also possible, for example, to use plates or small hard rubber discs as punching force transmission elements.
- a respective further recess has at least one locking element for holding the respective plate.
- This may be, for example, a displaceable or rotatable clamping element, a screw connection, or a tensioning element acting with spring force.
- a respective clamping element has a bolt for transmitting a clamping force.
- This bolt which can also be referred to as a bump, is in particular made of a high-strength, kink-resistant material such as steel.
- the clamping force of the closing frame is transmitted by the bolt to the punching and / or embossing tool located in the first recess. This will keep this safe.
- a respective clamping element is variable in its length from a first length for clamping a punching and / or embossing tool first format to a second length for clamping a punching and / or embossing tool second format.
- this graded length variability of the clamping element and a stepless change in length is possible, for example by providing a thread.
- An advantage of the use of a stepped adjustability by means of the dog clutch is that for the change in length of the clamping element there is only a small amount of time.
- this has a spring pin as a compression spring for holding a respective clamping element.
- This spring pin prevents a clamping element from slipping out during removal, storage and installation of the adapter unit and is lost.
- a respective clamping element may comprise a spring, which pulls a respective bolt into a recess in the adapter unit. If no clamping force is applied to a respective bolt from the outside, the spring force of the spring causes the clamping element to release the punching and / or stamping tool and this can be removed from the adapter unit.
- the number of punching force transmission elements and optionally also their distribution is chosen such that a punching and / or embossing force is approximately evenly distributed over the surface of a crucible of the punching and / or -gargestation. So z. Eg the Line density of steel strips symmetrical evenly distributed over the maximum format, ie the nominal format of the punching and / or embossing station.

Abstract
Description
Die Erfindung betrifft eine Adaptereinheit gemäß dem Oberbegriff von Anspruch 1 zur Aufnahme von Stanzwerkzeugen.The invention relates to an adapter unit according to the preamble of claim 1 for receiving punching tools.
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, Prägen, Ausbrechen, ggfs. Nutzentrennen 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 used for punching, embossing, breaking, if necessary. Nutzentrennen and storing sheets of paper, cardboard and the same be, 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 further has lateral carriages, which are connected to endless chains of the transport system and whereby the gripper carriage to be moved by 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.

Die
Die
Aufgabe der vorliegenden Erfindung ist es daher, den bekannten Stand der Technik weiter zu bilden und die oben genannten Probleme zumindest teilweise zu lösen.It is therefore an object of the present invention to further develop the known state of the art and to at least partially solve the abovementioned problems.
Gelöst wird diese Aufgabe durch eine Adaptereinheit mit den Merkmalen von Anspruch 1.This object is achieved by an adapter unit having the features of claim 1.
Die erfindungsgemäße Adaptereinheit weist eine erste Ausnehmung auf zur alternativen Aufnahme von Stanz- und/oder -prägewerkzeugen unterschiedlichen Formats in der Werkzeugaufnahme einer Stanz- und/oder -prägestation. Das Stanz- und/oder Prägewerkzeug kann dabei ein Plattenelement mit Wirkelementen wie Stanzmessern und/oder Rillmessern und/oder Prägeklischees umfassen. Die Adaptereinheit besitzt eine Mehrzahl von teleskopierbaren Klemmelementen zum Halten des Stanz- und/oder Prägewerkzeuges. Aufgrund der Teleskopierbarkeit der Klemmelemente ist in vorteilhafter Weise gewährleistet, dass das Werkzeug unterschiedliche Abmessungen aufweisen kann. Erfindungsgemäß weist die Adaptereinheit mindestens eine weitere Ausnehmung auf, in welcher eine Platte aufgenommen werden kann, die mit Kraftübertragungselementen bestückt ist. Diese Stanz- bzw. Prägekraftübertragungselemente dienen der Übertragung der Presskraft des Tiegels der Stanz- und/oder Prägestation und tragen so zu einer gleichmäßigeren Verteilung der Stanz- und/oder Prägekraft bei. Die Adaptereinheit entspricht in ihren Außenabmessungen dem Nennformat der Stanz- und/oder -prägestation. Gefertigt wird sie insbesondere aus einem plattenförmigen Element aus einem steifen, knickstabilen und leichtem Werkstoff, wie beispielsweise Aluminium oder faserverstärkter Kunststoff (z. Bsp. GFK oder CFK).The adapter unit according to the invention has a first recess for alternative recording of punching and / or stamping tools of different format in the tool holder of a punching and / or embossing station. The stamping and / or embossing tool may comprise a plate element with active elements such as punching knives and / or knives and / or embossing dies. The adapter unit has a plurality of telescopic clamping elements for holding the punching and / or embossing tool. Due to the telescoping of the clamping elements is ensured in an advantageous manner that the tool may have different dimensions. According to the invention, the adapter unit has at least one further recess in which a plate can be received, which is equipped with force transmission elements. These punching or embossing force transmission elements serve to transmit the pressing force of the crucible of the punching and / or embossing station and thus contribute to one more uniform distribution of the punching and / or stamping force. The adapter unit corresponds in its external dimensions to the nominal format of the punching and / or embossing station. It is manufactured in particular from a plate-shaped element made of a stiff, kink-resistant and lightweight material, such as aluminum or fiber-reinforced plastic (eg GFK or CFK).
In vorteilhafter Weiterbildung der erfindungsgemäßen Adaptereinheit ist mindestens eine, mit Stanzkraftübertragungselementen bestückte Platte Teil der Adaptereinheit. Die Platte kann dabei beispielsweise als Holzplatte ausgeführt sein.In an advantageous development of the adapter unit according to the invention, at least one plate equipped with punching force transmission elements is part of the adapter unit. The plate can be designed for example as a wooden plate.
In einer besonders vorteilhaften und daher bevorzugten Ausführungsform handelt es sich bei den Kraftübertragungselementen um Stanzmesser. Auch wenn an den Positionen der Stanzkraftübertragungselemente keine Bearbeitung eines in der Stanz- und/oder - prägestation zu bearbeitenden Bogens aus Papier, Pappe, Kunststoff und dergleichen gewünscht wird, stellt die Verwendung von Stanzmessern eine kostengünstige Variante dar. So können die mit Stanzmessern bestückten Platten bei den Stanz- und Prägewerkzeugherstellern in Auftrag gegeben werden. Alternativ zu den Stanzmessern können als Stanzkraftübertragungselemente jedoch beispielsweise auch Bleche oder kleine Hartgummischeiben zum Einsatz gelangen.In a particularly advantageous and therefore preferred embodiment, the force transmission elements are punching blades. Even if no machining of a sheet of paper, cardboard, plastic and the like to be processed in the punching and / or embossing station is desired at the positions of the punching force transmission elements, the use of punching knives represents a cost-effective variant. Thus, the plates equipped with punching knives to be commissioned by the stamping and stamping tool manufacturers. As an alternative to the punching blades, however, it is also possible, for example, to use plates or small hard rubber discs as punching force transmission elements.
In einer vorteilhaften Weiterbildung besitzt eine jeweilige weitere Ausnehmung mindestens ein Arretierelement zum Halten der jeweiligen Platte. Dabei kann es sich beispielsweise um ein verschiebliches oder drehbares Klemmelement, um eine Schraubenverbindung, oder um ein mit Federkraft wirkendes Spannelement handeln.In an advantageous development, a respective further recess has at least one locking element for holding the respective plate. This may be, for example, a displaceable or rotatable clamping element, a screw connection, or a tensioning element acting with spring force.
In einer besonders vorteilhaften und daher bevorzugten Ausführungsform weist ein jeweiliges Klemmelement einen Bolzen auf zur Übertragung einer Klemmkraft. Dieser Bolzen, welcher auch als Stösel bezeichnet werden kann, ist dabei insbesondere aus einem hochfesten, knickstabilen Werkstoff wie beispielsweise Stahl, hergestellt. In dem Fall, dass die Adaptereinheit in einem Schließrahmen auf genommen wird, wird die Klemmkraft des Schließrahmens durch den Bolzen auf das sich in der ersten Ausnehmung befindliche Stanz- und/oder Prägewerkzeug übertragen. Dadurch wird dieses sicher gehalten.In a particularly advantageous and therefore preferred embodiment, a respective clamping element has a bolt for transmitting a clamping force. This bolt, which can also be referred to as a bump, is in particular made of a high-strength, kink-resistant material such as steel. In the event that the adapter unit is accommodated in a closing frame, the clamping force of the closing frame is transmitted by the bolt to the punching and / or embossing tool located in the first recess. This will keep this safe.
In einer vorteilhaften Weiterbildung der erfindungsgemäßen Adaptereinheit ist ein jeweiliges Klemmelement in seiner Länge veränderlich von einer ersten Länge zum Klemmen eines Stanz- und/oder Prägewerkzeugs ersten Formats auf eine zweite Länge zum Klemmen eines Stanz- und/oder Prägewerkzeugs zweiten Formates. In vorteilhafter Weiterbildung weist ein jeweiliges Klemmelement eine Klauenkupplung auf mit zwei Ebenen zur Umsetzung der Längenveränderlichkeit. Sind die Elemente der Klauenkupplung in der ersten Ebene miteinander im Eingriff, so ist das Klemmelement von einer ersten Länge; Sind die Elemente der Klauenkupplung in der zweiten Ebene miteinander im Eingriff, so ist das Klemmelement von einer zweiten Länge. Alternativ zu dieser gestuften Längenveränderlichkeit des Klemmelements ist auch eine stufenlose Längenveränderung möglich, zum Beispiel durch Vorsehen eines Gewindes. Vorteilhaft an dem Einsatz einer gestuften Verstellbarkeit mittels der Klauenkupplung ist, dass für die Längenänderung des Klemmelements ein nur geringer Zeitbedarf besteht.In an advantageous development of the adapter unit according to the invention, a respective clamping element is variable in its length from a first length for clamping a punching and / or embossing tool first format to a second length for clamping a punching and / or embossing tool second format. In an advantageous embodiment, a respective clamping element on a claw coupling with two levels to implement the Längenveränderlichkeit. If the elements of the dog clutch are engaged with each other in the first plane, the clamping element is of a first length; If the elements of the dog clutch are engaged with each other in the second plane, the clamping element is of a second length. As an alternative to this graded length variability of the clamping element and a stepless change in length is possible, for example by providing a thread. An advantage of the use of a stepped adjustability by means of the dog clutch is that for the change in length of the clamping element there is only a small amount of time.
In einer Ausführungsvariante der erfindungsgemäßen Adaptereinheit besitzt diese zum Halten eines jeweiligen Klemmelements einen Federstift als Druckfeder. Dieser Federstift verhindert, dass ein Klemmelement beim Ausbauen, bei der Lagerung und beim Einbau der Adaptereinheit aus dieser heraus rutscht und verloren geht. Des Weiteren kann ein jeweiliges Klemmelement eine Feder aufweisen, welche einen jeweiligen Bolzen in eine Ausnehmung in der Adaptereinheit zieht. Wird von außen keine Klemmkraft auf einen jeweiligen Bolzen aufgebracht, so bewirkt die Federkraft der Feder, dass das Klemmelement das Stanz- und/oder -prägewerkzeug freigibt und dieses aus der Adaptereinheit entnommen werden kann.In one embodiment variant of the adapter unit according to the invention, this has a spring pin as a compression spring for holding a respective clamping element. This spring pin prevents a clamping element from slipping out during removal, storage and installation of the adapter unit and is lost. Furthermore, a respective clamping element may comprise a spring, which pulls a respective bolt into a recess in the adapter unit. If no clamping force is applied to a respective bolt from the outside, the spring force of the spring causes the clamping element to release the punching and / or stamping tool and this can be removed from the adapter unit.
In einer besonders vorteilhaften und daher bevorzugten Ausführungsform der Adaptereinheit ist die Anzahl der Stanzkraftübertragungselemente auf der mindestens einen Platte von der Anzahl und der Verteilung von Wirkelementen (also Stanzmesser, Rillmesser, Prägeklischees) eines jeweiligen Stanz- und/oder Prägewerkzeugs abhängig. Die Anzahl der Stanzkraftübertragungselemente und gegebenenfalls auch deren Verteilung ist dabei derart gewählt, dass eine Stanz- und/oder Prägekraft annähernd gleichverteilt über die Fläche eines Tiegels der Stanz- und/oder -prägestation ist. So kann z. Bsp. die Liniendichte von Bandstahlmessern symmetrisch gleichverteilt über das maximale Format, d.h. das Nennformat der Stanz- und/oder Prägestation sein. Um auf diesem Wege eine Gleichverteilung der Stanzkraft sicherzustellen, kann eine Sammlung von Platten mit verschiedener Anzahl an Stanzkraftübertragungselementen vorrätig gehalten werden, welche in Abhängigkeit von der Ausgestaltung des Stanz- und/oder Prägewerkzeuges in die mindestens eine weitere Ausnehmung der Adaptereinheit eingesetzt werden kann.In a particularly advantageous and therefore preferred embodiment of the adapter unit, the number of punching force transmission elements on the at least one plate on the number and distribution of active elements (ie punching, Rillmesser, embossing clichés) of a respective punching and / or embossing tool dependent. The number of punching force transmission elements and optionally also their distribution is chosen such that a punching and / or embossing force is approximately evenly distributed over the surface of a crucible of the punching and / or -prägestation. So z. Eg the Line density of steel strips symmetrical evenly distributed over the maximum format, ie the nominal format of the punching and / or embossing station. In order to ensure a uniform distribution of the punching force in this way, a collection of plates with different numbers of punching force transmission elements can be kept in stock, which can be used depending on the configuration of the punching and / or embossing tool in the at least one further recess of the adapter unit.
