Description

Die Erfindung betrifft eine Vorrichtung sowie ein Verfahren zur Durchführung wenigstens eines Schnittvorganges zwecks Herstellung eines Buches, einer Broschüre oder dergleichen, insbesondere eines buchartigen Identifikationsdokumentes wie eines Passbuches.The invention relates to a device and a method for performing at least one cutting process for the purpose of producing a book, a brochure or the like, in particular a book-like identification document such as a passport book.

Ein Buch umfasst Seiten, die an einem Rücken gebunden sind. Zuzüglich zu den Seiten kann ein Buch einen Bucheinband aufweisen, der Deckel umfasst. Das Buch wird in einem der letzten Herstellungsschritte auf sein endgültiges Format gebracht, indem das Buch an den nicht gebundenen Seiten des Buches beschnitten wird. Dies ist notwendig, um Ungenauigkeiten beim Schneiden eines Druckbogens ausgleichen zu können und gleichmäßige Kanten des Buches zu ermöglichen.A book has pages that are bound on a spine. In addition to the pages, a book can have a book cover that includes a cover. In one of the last manufacturing steps, the book is brought to its final format by trimming the unbound pages of the book. This is necessary in order to be able to compensate for inaccuracies when cutting a printed sheet and to enable even edges of the book.

Nach dem Stand der Technik werden Bücher, insbesondere Passbücher, vor dem Beschnitt in einer für den Beschnitt geeigneten Vorrichtung fixiert, insbesondere durch das Pressen oder Spannen des Buches zwischen zwei Einspannungen. Das jeweilige Buch wird dadurch positionstreu gehalten.According to the prior art, books, in particular passport books, are fixed in a device suitable for the trimming before trimming, in particular by pressing or tensioning the book between two clamps. The respective book is kept true to its position.

Der Rücken ist ausgebildet durch ein Formelement, welches die im Wesentlichen parallel zueinander angeordneten Deckel bzw. die erste und die letzte Seiten des Buches, die sogenannten Deckseiten, miteinander verbindet. Üblicherweise hat ein derartiger Rücken eine zwischen den genannten Deckeln bzw. Deckseiten verlaufende konvexe Form. Er wird daher nicht durch das Pressen des Buches positionstreu gehalten. Beim Beschnitt des Buches kann es zu Verformungen des Rückens und infolgedessen zu Beschädigungen insbesondere in Form leichter Ausrisse an der seitlichen Begrenzung des Rückens kommen. Die Beschädigung tritt insbesondere an der Stelle auf, an der die seitliche Begrenzung des Rückens in die seitliche Begrenzungskante eines angeschlossenen Deckels bzw. einer Deckseite übergeht. Mit den seitlichen Begrenzungen des Rückens sind die Bereiche gemeint, die den Rücken an dessen entlang seiner Längserstreckung gegenüberliegenden Seiten begrenzen. Die Beschädigungen treten bei verschiedenen Techniken für den Beschnitt, einschließlich dem Schneiden und dem Fräsen, auf. Sie mindern den optischen Eindruck des Buches und sollen verhindert werden.The spine is formed by a shaped element which connects the covers, which are arranged essentially parallel to one another, or the first and last pages of the book, the so-called cover pages, to one another. Such a back usually has a convex shape running between the mentioned lids or top sides. It is therefore not held in the correct position by pressing the book. When the book is trimmed, the spine can be deformed and, as a result, damaged, especially in the form of slight tears on the side of the spine. The damage occurs in particular at the point at which the lateral delimitation of the back merges into the lateral delimiting edge of a connected cover or a cover side. The lateral delimitations of the back mean the areas which delimit the back on its opposite sides along its longitudinal extent. The damage occurs with various techniques for trimming, including cutting and milling. They reduce the visual impression of the book and should be prevented.

Diese Aufgabe wird durch die Vorrichtung zur Durchführung wenigstens eines Schnittvorganges nach Anspruch 1 und das Verfahren zur Durchführung wenigstens eines Schnittvorganges nach Anspruch 8 gelöst. Vorteilhafte Ausführungsformen der Vorrichtung sind in den Unteransprüchen 2 bis 7 angegeben. Vorteilhafte Ausführungsformen des Verfahrens sind in den Unteransprüchen 9 bis 13 angegeben. Diese und weitere Ausführungsformen werden im Folgenden beschrieben.This object is achieved by the device for carrying out at least one cutting process according to claim 1 and the method for carrying out at least one cutting process according to claim 8. Advantageous embodiments of the device are specified in subclaims 2 to 7. Advantageous embodiments of the method are specified in the dependent claims 9 to 13. These and other embodiments are described below.

Ein erster Aspekt der Erfindung betrifft eine Vorrichtung zur Durchführung wenigstens eines Schnittvorganges zwecks Herstellung eines Buches, einer Broschüre oder dergleichen, insbesondere eines buchartigen Identifikationsdokumentes wie eines Passbuches, welches Buchseiten umfasst, die an einem Rücken gebunden sind. Dabei weist die Vorrichtung ein Aufnahmeelement zur Aufnahme des Buches in einer ersten Ebene auf. Des Weiteren umfasst die Vorrichtung ein Schnittelement zur Beaufschlagung des Buches mit einer Schnittkraft in einer zweiten Ebene im Wesentlichen senkrecht zur ersten Ebene. Die Vorrichtung weist weiterhin mindestens eine mit dem Aufnahmeelement mechanisch fest verbundene Stützvorrichtung auf, an der wenigstens ein Bereich des Rückens anordbar ist und mit der bei Einwirkung der Schnittkraft auf das Buch wenigstens ein Bereich des Rückens mit einer der Schnittkraft im Wesentlichen entgegen gerichteten Abstützkraft abstützbar ist.A first aspect of the invention relates to a device for carrying out at least one cutting process for the purpose of producing a book, a brochure or the like, in particular a book-like identification document such as a passport book, which comprises book pages which are bound on a spine. The device has a receiving element for receiving the book in a first plane. Furthermore, the device comprises a cutting element for applying a cutting force to the book in a second plane essentially perpendicular to the first plane. The device furthermore has at least one support device mechanically firmly connected to the receiving element, on which at least one area of the back can be arranged and with which at least one area of the back can be supported with a support force essentially opposing the cutting force when the cutting force acts on the book .

Es ist erfindungsgemäß vorgesehen, dass die Stützvorrichtung einen konkav gewölbten Bereich aufweist, an den der Rücken formschlüssig anlegbar ist und dass die Vorrichtung mindestens eine Greifvorrichtung aufweist, die mindestens zwei Greifarme umfasst, mit denen das Buch mechanisch Greifbar ist.It is provided according to the invention that the support device has a concavely arched area against which the spine can be placed in a form-fitting manner and that the device has at least one gripping device comprising at least two gripping arms with which the book can be gripped mechanically.

Unter einem Aufnahmeelement ist dabei z.B. eine Matrize zur pressenden oder spannenden und damit fixierenden Aufnahme des Buches zu verstehen.A receiving element is to be understood as meaning, for example, a die for pressing or tensioning and thus securing the book.

Die erfindungsgemäße Vorrichtung ist von Vorteil, da sie ein Abstützen zumindest eines Teils des Rückens ermöglicht und somit der Verformung des Rückens bei Einwirkung der Schnittkraft und der damit verbundenen Beschädigungen in Form leichter Ausrisse im Bereich des Rückens entgegenwirkt.The device according to the invention is advantageous because it supports at least one Part of the back allows and thus the deformation of the back when exposed to the Counteracts cutting force and the associated damage in the form of slight tears in the area of the back.

Eine erfindungsgemäße Ausführungsform sieht vor, dass die Kontur des konkav gewölbten Bereiches parallel zur zweiten Ebene im Wesentlichen einem Viertelkreis entspricht.An embodiment according to the invention provides that the contour of the concavely curved area corresponds essentially to a quarter circle parallel to the second plane.

Diese Ausführungsform ist vorteilhaft, da sie ein formschlüssiges Anlegen vom Rücken mit seiner konvex ausgebildeten Form an die Stützvorrichtung ermöglicht. Passbücher weisen eine derartige Form des Rückens auf.This embodiment is advantageous because it enables a form-fitting application of the back with its convex shape to the support device. Passport books have such a shape of the spine.

Eine vorteilhafte erfindungsgemäße Ausführungsform sieht vor, dass die Stützvorrichtung derart ausgebildet ist, dass der Rücken bis zu seiner Scheitellinie formschlüssig an der Stützvorrichtung anliegen kann. Mit der Scheitellinie ist dabei die Linie gemeint, die entlang der Rücken-Längsausdehnung durch die Zenit-Punkte bzw. Maxima der konvexen Rückenwölbung ausgebildet ist.An advantageous embodiment according to the invention provides that the support device is designed in such a way that the back can rest against the support device in a form-fitting manner up to its apex line. The apex line here means the line which is formed along the longitudinal extension of the back through the zenith points or maxima of the convex back curvature.

Nach einer weiteren Ausführungsform ist die Vorrichtung derart eingerichtet, dass die Stützvorrichtung wenigstens zwei voneinander beabstandete Stützelemente aufweist, zwischen denen ein Zwischenraum ausgebildet ist. Wenn das Buch in oder an dem Aufnahmeelement positioniert ist, wird durch den Zwischenraum ein Zugang zumindest zu einem Teil des Rückens ermöglicht.According to a further embodiment, the device is set up in such a way that the support device has at least two spaced-apart support elements, between which an intermediate space is formed. When the book is positioned in or on the receiving element, access to at least part of the spine is made possible through the gap.

Dabei können die zwei Stützelemente durch ein gemeinsames Bauteil ausgebildet sein, das eine entsprechende Aussparung aufweist. Alternativ können die zwei Stützelemente ebenso durch zwei einzelne Bauteile ausgebildet sein, die voneinander beabstandet positioniert sind.The two support elements can be formed by a common component which has a corresponding recess. Alternatively, the two support elements can also be formed by two individual components which are positioned at a distance from one another.

Die Erfindung ist dabei nicht auf zwei Stützelemente und/oder einen ausgebildeten Zwischenraum beschränkt. Sie umfasst ebenso Ausführungsformen, die mehr als zwei Stützelemente aufweisen und in denen somit mehr als ein Zwischenraum ausgebildet ist.The invention is not limited to two support elements and / or a formed space. It also includes embodiments which have more than two support elements and in which more than one intermediate space is thus formed.

Bei dieser erfindungsgemäßen Ausführungsform ist von Vorteil, dass bei Anlage eines Buches dessen Rücken durch die Stützvorrichtung abgestützt ist und zudem ein Zugriff zumindest auf einen Teil des Rückens ermöglicht ist.In this embodiment according to the invention, it is advantageous that when a book is placed, its spine is supported by the support device and, in addition, access to at least part of the spine is made possible.

Gemäß einer Ausführungsform der Erfindung ist vorgesehen, dass die Stützvorrichtung derart eingerichtet und angeordnet ist, dass sie bündig oder mit einem minimalen Abstand mit der Ebene abschließt, in der die Schnittkraft auf das Buch aufgebracht wird. Der Abstand beträgt maximal 1 mm, insbesondere maximal 0,5 mm.According to one embodiment of the invention it is provided that the supporting device is set up and arranged in such a way that it ends flush with or with a minimal distance from the plane in which the cutting force is applied to the book. The distance is a maximum of 1 mm, in particular a maximum of 0.5 mm.

Mit dem Abstand ist die Distanz zwischen der Stützvorrichtung und dem Schnittelement bzw. dessen Schneidkante gemeint, wenn der Schnittvorgang vorgenommen wird. In der Ebene, in der die Schnittkraft auf das Buch aufgebracht wird, verläuft die Schnittkante, die durch ein Trennverfahren, insbesondere durch Schneiden oder Fräsen, hergestellt wird.The distance between the support device and the cutting element or its cutting edge is meant when the cutting process is carried out. In the plain in which the cutting force is applied to the book, the cut edge runs, which is produced by a cutting process, in particular by cutting or milling.

Diese Ausführungsform der Vorrichtung ist von Vorteil, da insbesondere die Bereiche des Rückens abgestützt werden, die durch die Schnittkanten begrenzt sind.This embodiment of the device is advantageous because in particular the areas of the back that are delimited by the cut edges are supported.

Gemäß einer weiteren Ausführungsform der Vorrichtung ist vorgesehen, dass die Stützvorrichtung von einer Kante oder einer Grenzebene an der von der ersten Ebene abgewandten Seite begrenzt ist. Dabei weist die Kante oder die Grenzebene einen Abstand von mindestens 3 mm zur ersten Ebene auf.According to a further embodiment of the device it is provided that the support device is delimited by an edge or a boundary plane on the side facing away from the first plane. The edge or the boundary plane is at a distance of at least 3 mm from the first plane.

Mit anderen Worten bedeutet das, dass die Kante oder die Grenzebene in einer Ebene um mindestens 3 mm versetzt zur ersten Ebene angeordnet ist. Ist die erste Ebene als untere Ebene eingerichtet, so erstreckt sich die Kante oder die Grenzebene um mindestens 3 mm über dieser. Insbesondere ist die Kante oder die Grenzebene mit einem derartigen Abstand zur ersten Ebene angeordnet, dass sie sich in einer Ebene mit der Scheitellinie eines Rückens eines an die Stützvorrichtung angelegten Rückens befindet. Insbesondere verläuft die Kante oder die Grenzebene parallel zur ersten Ebene.In other words, this means that the edge or the boundary plane is arranged in a plane offset by at least 3 mm to the first plane. If the first level is set up as the lower level, the edge or the boundary level extends above this by at least 3 mm. In particular, the edge or the boundary plane is arranged at such a distance from the first plane that it is located in a plane with the apex line of a back of a back placed on the support device. In particular, the edge or the boundary plane runs parallel to the first plane.

Damit wird erfindungsgemäß ermöglicht, dass der Rücken mindestens in einem Abstand von 3 mm senkrecht zur ersten Ebene von der Stützvorrichtung abstützbar ist.According to the invention, this enables the back to be supported by the support device at least at a distance of 3 mm perpendicular to the first plane.

Erfindungsgemäß ist die Vorrichtung derart eingerichtet, dass sie weiterhin mindestens eine Greifvorrichtung aufweist, die mindestens zwei Greifarme umfasst, mit denen das Buch mechanisch greifbar ist.According to the invention, the device is set up in such a way that it furthermore has at least one gripping device which comprises at least two gripping arms with which the book can be gripped mechanically.

Die Greifarme weisen Kontaktbereiche auf und sind derart eingerichtet und angeordnet oder anordbar, dass die Kontaktbereiche an dem Buch positionierbar sind. Die Kontaktbereiche weisen insbesondere ein nachgiebiges Material auf, insbesondere ein Polymer. Dies ermöglicht, dass durch die Kontaktbereiche keine Beschädigungen des Buches hervorgerufen werden, wenn die Kontaktbereiche ans Buch angelegt werden bzw. an dem Buch anliegen. Zudem wirkt eine Reibungskraft zwischen den Kontaktbereichen aus nachgiebigem Material und dem angelegten Buch, so dass ein Gleiten des Buches zwischen den Greifarmen oder ein Gleiten des Buches aus den Greifarmen heraus erschwert bzw. verhindert wird.The gripping arms have contact areas and are set up and arranged or can be arranged such that the contact areas can be positioned on the book. In particular, the contact areas have a flexible material, in particular a polymer. This makes it possible that the contact areas do not cause any damage to the book when the contact areas are placed against the book or are in contact with the book. In addition, a frictional force acts between the contact areas made of flexible material and the applied book, so that sliding of the book between the gripping arms or sliding of the book out of the gripping arms is made more difficult or prevented.

Die erfindungsgemäße Vorrichtung hat den Vorteil, dass sie neben dem Stützen und dem Beschnitt eines Buches ebenfalls das Greifen des Buches durch die Greifarme zwecks Bewegung des Buches ermöglicht. Durch die erfindungsgemäße vorteilhafte Ausführungsform der Kontaktbereiche, ist dabei keine Beschädigung des Buches zu befürchten.The device according to the invention has the advantage that, in addition to supporting and trimming a book, it also enables the book to be gripped by the gripping arms for the purpose of moving the book. Due to the advantageous embodiment of the contact areas according to the invention, there is no risk of damage to the book.

Gemäß einer Ausführungsform der Vorrichtung ist vorgesehen, dass zumindest ein Teil einer Greifvorrichtung innerhalb des Zwischenraumes, der zwischen den Stützelementen ausgebildet ist, angeordnet oder anordbar ist.According to one embodiment of the device it is provided that at least a part of a gripping device is arranged or can be arranged within the intermediate space which is formed between the support elements.

Diese vorteilhafte erfindungsgemäße Ausführungsform umfasst, dass zumindest ein Teil eines Greifarmes bzw. eines Kontaktbereiches innerhalb des Zwischenraumes angeordnet oder anordbar ist. Mindestens einem Teil eines Greifarmes bzw. eines Kontaktbereiches wird derart ermöglicht, an das Buch angelegt zu werden, wobei das Buch in oder auf dem Aufnahmeelement angelegt ist und der Rücken an der Stützvorrichtung anliegt. Das bedeutet, dass der Greifvorrichtung durch den Zwischenraum Zugriff zu dem Buch ermöglicht wird, während dessen Rücken an der Stützvorrichtung anliegt.This advantageous embodiment according to the invention comprises that at least a part of a gripping arm or a contact area is arranged or can be arranged within the intermediate space. At least one part of a gripping arm or a contact area is thus made possible to be placed against the book, the book being placed in or on the receiving element and the spine resting against the support device. This means that the gripping device is enabled to access the book through the intermediate space, while its spine rests against the support device.

Die Erfindung umfasst zudem, dass das Aufnahmeelement, mit dem die Stützvorrichtung mechanisch fest verbunden ist, einen Leerraum aufweist, der in den Zwischenraum übergeht. Damit wird vorteilhaft ermöglicht, dass die Greifvorrichtung nicht nur im Bereich des Rückens Zugriff auf das Buch erhält, sondern ebenfalls zu dem Bereich des Buches, mit dem es den Leerraum überbrückt. Damit wird ein verbessertes und sichereres Greifen des Buches ermöglicht, da eine größere Fläche des Buches mithilfe der Greifarme gegriffen werden kann.The invention also includes that the receiving element, with which the support device is mechanically firmly connected, has an empty space which merges into the intermediate space. This advantageously enables the gripping device to gain access to the book not only in the area of the back, but also to the area of the book with which it bridges the empty space. This enables an improved and safer gripping of the book, since a larger area of the book can be gripped with the aid of the gripping arms.

Nach einer weiteren Ausführungsform ist die Greifvorrichtung derart verschiebbar, dass entgegengesetzt zur Wirkrichtung der Schnittkraft mindestens eine Strecke überwindbar ist, die dem Abstand der Kante oder der Grenzebene der Stützvorrichtung zur ersten Ebene entspricht. Somit ist mindestens ein Teil eines Greifarmes zumindest derart bewegbar, dass sich ein Kontaktbereich des Greifarmes, mit dem der Greifarm an das Buch anlegbar ist, mindestens in einer Ebene mit der Kante oder Grenzebene befindet oder sich zwischen dem Kontaktbereich und der ersten Ebene ein größerer Abstand befindet als zwischen der Kante oder der Grenzebene der Stützvorrichtung und der ersten Ebene.According to a further embodiment, the gripping device is displaceable in such a way that, opposite to the effective direction of the cutting force, at least a distance can be overcome which corresponds to the distance between the edge or the boundary plane of the support device and the first plane. Thus, at least part of a gripper arm can be moved at least in such a way that a contact area of the gripper arm with which the gripper arm can be placed against the book is at least in one plane with the edge or boundary plane or there is a greater distance between the contact area and the first plane located than between the edge or the boundary plane of the support device and the first plane.

Mit anderen Worten bedeutet das, dass ein Buch, das in einer Ausgangsposition auf einem Aufnahmeelement aufliegt und mittels der Greifvorrichtung gegriffen ist, durch eine Bewegung der Greifvorrichtung anhebbar ist. Damit wird das Buch aus der ersten Ebene herausbewegt. Das bedeutet, dass es von dem Aufnahmeelement wegbewegt wird. Dabei ist das Buch soweit anhebbar, dass sich das Buch oberhalb der Kante oder der Grenzebene der Stützvorrichtung befindet. Insbesondere kann die Bewegung der Greifvorrichtung, mit der ein gegriffenes Buch aus der ersten Ebene hinausbewegt wird, pneumatisch realisiert werden.In other words, this means that a book which rests on a receiving element in an initial position and is gripped by means of the gripping device can be lifted by a movement of the gripping device. This moves the book out of the first level. This means that it is moved away from the receiving element. The book can be raised so far that the book is above the edge or the boundary plane of the support device. In particular, the movement of the gripping device, with which a gripped book is moved out of the first level, can be realized pneumatically.

Die erfindungsgemäße Ausführungsform ist nicht darauf beschränkt, dass die Greifvorrichtung derart bewegt wird, dass ein fixiertes Buch angehoben wird. Umfasst wird allgemein eine Bewegung der Greifvorrichtung senkrecht zur ersten Ebene.The embodiment according to the invention is not restricted to the fact that the gripping device is moved in such a way that a fixed book is lifted. A movement of the gripping device perpendicular to the first plane is generally included.

Diese Ausführungsform der Vorrichtung ist von Vorteil, da durch die erfindungsgemäße Bewegung der Greifvorrichtung das mit den Greifarmen fixierte Buch aus der ersten Ebene herausbewegt wird, die an einer Seite durch die Stützvorrichtung begrenzt ist. Diese Begrenzung verhindert die Bewegung des Buches in der ersten Ebene aus der Aufnahmeeinrichtung heraus bzw. schränkt die Richtungen ein, in denen das Buch in der ersten Ebene bewegt werden kann. Mithilfe der vorteilhaften Ausführungsform der Vorrichtung wird diese Einschränkung möglicher Bewegungsrichtungen aufgehoben. Dies umfasst, dass die Voraussetzung geschaffen wird, dass ein mittels der Greifvorrichtung gegriffenes Buch in einem nächsten Schritt über die Kante oder Grenzebene hinweg aus der Stützvorrichtung herausbewegt werden kann, ohne mit der Stützvorrichtung zu kollidieren. So wird in einfacher Weise ermöglicht, dass das Buch einer weiteren Vorrichtung zur Herstellung oder einer Lagerstätte zugeführt werden kann. Des Weiteren wird die Möglichkeit gegeben, dass das Aufnahmeelement ein nächstes Buch aufnehmen kann.This embodiment of the device is advantageous because the movement of the gripping device according to the invention moves the book fixed with the gripping arms out of the first plane, which is delimited on one side by the support device. This limitation prevents the movement of the book in the first plane out of the receiving device or restricts the directions in which the book can be moved in the first plane. With the aid of the advantageous embodiment of the device, this restriction on possible directions of movement is eliminated. This includes that the prerequisite is created that a book gripped by means of the gripping device can be moved out of the supporting device in a next step over the edge or boundary plane without colliding with the supporting device. It is thus made possible in a simple manner that the book can be fed to a further device for production or to a storage facility. Furthermore, the possibility is given that the receiving element can receive a next book.

Insbesondere ist eine Ausführungsform der Vorrichtung von Vorteil, in der die Kante oder die Grenzebene mit einem solchen Abstand zur ersten Ebene angeordnet ist, dass sie sich in einer Ebene mit der Scheitellinie eines Rückens eines an die Stützvorrichtung angelegten Rückens befindet. Damit wird der Rücken an seiner der ersten Ebene zugewandten Seite vollständig abgestützt. Zudem wird ermöglicht, dass das Buch ohne Kollision mit der Stützvorrichtung durch eine Bewegung senkrecht zur Wirkrichtung der Schnittkraft aus der ersten Ebene herausbewegt werden kann. Weiterhin wird ermöglicht, dass das Buch um eine minimale Strecke bewegt wird, um über die Kante oder Grenzebene hinweg aus der Stützvorrichtung herausbewegt zu werden.In particular, an embodiment of the device is advantageous in which the edge or the boundary plane is arranged at such a distance from the first plane that it is in a plane with the apex line of a back of a back placed on the support device. In this way, the back is completely supported on its side facing the first level. In addition, it is made possible that the book can be moved out of the first plane by a movement perpendicular to the effective direction of the cutting force without colliding with the support device. It also enables the book to be moved a minimal distance in order to be moved out of the support device over the edge or boundary plane.

Gemäß einer Ausführungsform der Vorrichtung ist vorgesehen, dass die Greifvorrichtung zwecks Greifens des Buchs pneumatisch angetrieben oder antreibbar ist.According to one embodiment of the device it is provided that the gripping device is pneumatically driven or drivable for the purpose of gripping the book.

Der pneumatische Antrieb dieser erfindungsgemäßen Ausführungsform ist von Vorteil, da bei pneumatisch betriebenen Systemen die Abluft an die Umgebung abgegeben werden kann und daher die Vorrichtung keine Rückleitungen umfassen muss. Dies erleichtert die Wartung der Vorrichtung. Des Weiteren sind aufgrund der verwandten Pneumatik keine Verunreinigungen zu befürchten sowie auftretende Kräfte flexibel einstellbar.The pneumatic drive of this embodiment according to the invention is advantageous because, in pneumatically operated systems, the exhaust air can be released into the environment and therefore the device does not have to include any return lines. This facilitates the maintenance of the device. Furthermore, due to the pneumatics used, there is no risk of contamination and the forces that occur can be flexibly adjusted.

Ein weiterer Aspekt der Erfindung betrifft ein Verfahren zur Durchführung wenigstens eines Schnittvorganges zwecks Herstellung eines Buches, einer Broschüre oder dergleichen, insbesondere eines buchartigen Identifikationsdokumentes wie eines Passbuches, welches Buchseiten umfasst, die an einem Rücken gebunden sind. Dabei wird eine erfindungsgemäße Vorrichtung zur Verfügung gestellt und der Vorrichtung ein Buch zugeführt. Das Buch wird in oder auf dem Aufnahmeelement aufgenommen, mit seinem Rücken an die Stützvorrichtung angelegt und in oder auf dem Aufnahmeelement gespannt. Das Buch wird mittels eines Schnittelementes mit einer Schnittkraft, von der zumindest eine Komponente senkrecht zur Ebene des Aufnahmeelements verläuft, beaufschlagt, wobei die Stützvorrichtung entgegen der Wirkrichtung der Schnittkraft eine Abstützkraft auf wenigstens einen Bereich des Rückens ausübt.Another aspect of the invention relates to a method for carrying out at least one cutting process for the purpose of producing a book, a brochure or the like, in particular a book-like identification document such as a passport book, which comprises book pages which are bound on a spine. A device according to the invention is provided and a book is supplied to the device. The book is received in or on the receiving element, placed with its back on the support device and stretched in or on the receiving element. A cutting force is applied to the book by means of a cutting element, at least one component of which runs perpendicular to the plane of the receiving element, the supporting device exerting a supporting force on at least one area of the back against the effective direction of the cutting force.

Dabei wird ein Trennverfahren, insbesondere das Schneiden oder Fräsen, an mindestens einer der nicht gebundenen Begrenzungsseiten des Buches ausgeübt. Dabei wirkt eine von der Stützvorrichtung ausgeübte Abstützkraft mit wenigstens einer Komponente senkrecht zur ersten Ebene und damit auch entgegen wenigstens einer Komponente der Schnittkraft.A separating process, in particular cutting or milling, is carried out on at least one of the unbound boundary pages of the book. In this case, a supporting force exerted by the supporting device acts with at least one component perpendicular to the first plane and thus also against at least one component of the cutting force.

Vorteilhaft bei dieser erfindungsgemäßen Ausführungsform des Verfahrens ist, dass mindestens während des Schnittvorganges der Rücken an der Stützvorrichtung anliegt, die eine Kraft bewirkt, die der Schnittkraft entgegenwirkt und so einer Beschädigung im Bereich des Rückens entgegenwirken kann.The advantage of this embodiment of the method according to the invention is that at least during the cutting process the back rests against the support device, which causes a force that counteracts the cutting force and can thus counteract damage in the area of the back.

Gemäß einer Ausführungsform des Verfahrens wird das Buch mittels der Greifarme gegriffen, so dass bei einer Bewegung der Greifarme das Buch entsprechend bewegt wird.According to one embodiment of the method, the book is gripped by means of the gripping arms, so that when the gripping arms move, the book is moved accordingly.

Nach Durchführung eines Schnittvorganges wird die Spannung des Buches beendet. Die Greifarme werden mit dem Buch in einer Richtung entgegengesetzt zur Wirkrichtung der Schnittkraft bewegt, so dass das Buch aus der ersten Ebene herausbewegt wird.After a cutting process has been carried out, the tension on the book is terminated. The gripping arms are moved with the book in a direction opposite to the effective direction of the cutting force, so that the book is moved out of the first plane.

Dabei kann die gesamte Greifvorrichtung mit den Greifarmen und dem fixierten Buch bewegt werden. Alternativ kann lediglich ein Abschnitt der Greifvorrichtung derart bewegt werden, dass mindestens die Greifarme entgegengesetzt zur Wirkrichtung der Schnittkraft bewegt werden. Ein Buch, das mittels der Greifarme fixiert ist, wird entsprechend mitbewegt und aus der ersten Ebene herausbewegt, so dass es nicht mehr in oder auf dem Aufnahmeelement aufgenommen ist.The entire gripping device with the gripping arms and the fixed book can be moved. Alternatively, only a section of the gripping device can be moved in such a way that at least the gripping arms are moved in the opposite direction to the effective direction of the cutting force. A book that is fixed by means of the gripping arms is moved along with it and moved out of the first plane so that it is no longer received in or on the receiving element.

Eine weitere Ausführungsform des Verfahrens sieht vor, dass die Greifarme zumindest um 3 mm in einer Richtung entgegengesetzt zur Wirkrichtung der Schnittkraft bewegt werden, so dass das Buch aus der ersten Ebene herausbewegt wird.Another embodiment of the method provides that the gripping arms are moved at least 3 mm in a direction opposite to the effective direction of the cutting force, so that the book is moved out of the first plane.

Das bedeutet, dass die Greifarme derart entgegengesetzt zur Wirkrichtung der Schnittkraft bewegt werden, dass ein Kontaktbereich, mit dem ein Greifarm an das Buch anlegbar ist, mindestens auf die Ebene der Kante oder der Grenzebene der Stützvorrichtung bewegt wird. Ein Buch, das mittels der Greifarme gegriffen ist, wird entsprechend mitbewegt, wodurch dessen Anlage an der Stützvorrichtung aufgehoben wird. Die Greifarme und das fixierte Buch werden mindestens um die Strecke bewegt, die dem Abstand zwischen der ersten Ebene und der Kante oder Grenzebene der Stützvorrichtung entspricht. In einer erfindungsgemäßen Ausführungsform entspricht dieser Abstand 3 mm. Die Erfindung ist jedoch nicht auf diesen Abstand begrenzt.This means that the gripping arms are moved opposite to the effective direction of the cutting force in such a way that a contact area with which a gripping arm can be placed against the book is moved at least to the level of the edge or the boundary plane of the support device. A book that is gripped by means of the gripping arms is moved accordingly, whereby its contact with the support device is canceled. The gripping arms and the fixed book are moved at least by the distance which corresponds to the distance between the first plane and the edge or boundary plane of the support device. In one embodiment according to the invention, this distance corresponds to 3 mm. However, the invention is not limited to this distance.

Eine erfindungsgemäße Ausführungsform des Verfahrens sieht vor, dass die Bewegung der Greifarme in einer Richtung entgegengesetzt zur Wirkrichtung der Schnittkraft pneumatisch realisiert wird.An embodiment of the method according to the invention provides that the movement of the gripping arms is realized pneumatically in a direction opposite to the effective direction of the cutting force.

Diese Ausführungsform des Verfahrens ist von Vorteil, da durch die erfindungsgemäße Bewegung der Greifvorrichtung ein Buch, das mittels der Greifarme fixierte ist, derart bewegt wird, dass es aus dem Bereich, in dem die Stützvorrichtung eine Einschränkung der Bewegungsrichtung des Buches ausübt, herausbewegt ist.This embodiment of the method is advantageous because the inventive movement of the gripping device moves a book that is fixed by means of the gripping arms in such a way that it is moved out of the area in which the support device restricts the direction of movement of the book.

Nach einer weiteren Ausführungsform des Verfahrens, werden mindestens die Greifarme weiterhin derart bewegt, dass das mit den Greifarmen gegriffene Buch aus dem Projektionsbereich des Aufnahmeelements und der Stützvorrichtung herausbewegt wird.According to a further embodiment of the method, at least the gripping arms are further moved in such a way that the book gripped with the gripping arms is moved out of the projection area of the receiving element and the support device.

Mit anderen Worten bedeutet das, dass das Buch aus einem Raum bewegt wird, dessen Grundfläche durch die Ränder des Aufnahmeelementes sowie der Stützvorrichtung begrenzt ist, nachdem das Buch mittels der Greifvorrichtung angehoben wurde.In other words, this means that the book is moved out of a space, the base area of which is delimited by the edges of the receiving element and the supporting device, after the book has been lifted by means of the gripping device.

Dadurch wird ermöglicht, dass das Buch auf einfache Weise einer Lagerstätte oder einer weiteren Vorrichtung zur Herstellung zugeführt werden kann. Des Weiteren wird die Möglichkeit gegeben, dass das Aufnahmeelement ein nächstes Buch aufnehmen kann.This enables the book to be easily supplied to a storage facility or to another device for production. Furthermore, the possibility is given that the receiving element can receive a next book.

Eine weitere Ausführungsform des Verfahrens sieht vor, dass der Schnittvorgang durch eine translatorische Bewegung eines als Messer ausgestalteten Schnittelementes oder durch eine rotatorische Bewegung eines als Fräser ausgestalteten Schnittelementes realisiert wird.A further embodiment of the method provides that the cutting process is implemented by a translatory movement of a cutting element designed as a knife or by a rotary movement of a cutting element designed as a milling cutter.

Beschädigungen des Rückens können sowohl beim Beschnitt durch ein translatorisch bewegtes Messer als auch bei Beschnitt durch Fräsen auftreten. Die erfindungsgemäße Vorrichtung und das erfindungsgemäße Verfahren können insbesondere bei diesen beiden gängigen Techniken des Beschnitts einer Beschädigung des Rückens entgegenwirken und den optischen Eindruck des Buches nach dem Beschnitt verbessern. Dies ermöglicht eine vielseitige Einsetzbarkeit der erfindungsgemäßen Vorrichtung und des erfindungsgemäßen Verfahrens.Damage to the back can occur both when trimmed by a knife moving in a translatory manner and when trimmed by milling. The device according to the invention and the method according to the invention can counteract damage to the back, in particular with these two common techniques of trimming, and improve the visual impression of the book after trimming. This enables versatile applicability of the device according to the invention and the method according to the invention.

Die erfindungsgemäße Vorrichtung und das erfindungsgemäße Verfahren sind vielseitig gewerblich anwendbar. Sie können für den Beschnitt unterschiedlicher Ausführungsformen von Büchern, Broschüren oder dergleichen verwandt werden. Insbesondere können sie beim Beschnitt eines buchartigen Identifikationsdokumentes wie eines Passbuches eingesetzt werden.The device according to the invention and the method according to the invention are industrially applicable in many ways. They can be used for trimming different types of books, brochures or the like. In particular, they can be used when trimming a book-like identification document such as a passport book.

Die Figur 1 zeigt eine perspektivische teilweise aufgeschnittene Darstellung eines Ausschnitts einer Vorrichtung zur Durchführung wenigstens eines Schnittvorganges 10 gemäß der vorliegenden Erfindung, die eine Stützvorrichtung 30 zum Abstützen zumindest eines Bereiches eines Rückens 74 während des Schnittvorganges zur Herstellung des Buches 70 aufweist. Die Vorrichtung 10 umfasst ein Gehäuse 1. Ein Buch 70 ist auf der unteren Einspannung 16 positionsgenau platziert. Die untere Einspannung 16 umfasst ein unteres Aufnahmeelement 12, das eine Auflagefläche für ein Buch 70 ausbildet. Die obere Einspannung 18, die das obere Aufnahmeelement 14 sowie ein Schnittelement umfasst, ist verfahrbar. Sie ist zum Buch 70 beabstandet. Das Buch 70 liegt auf der unteren Einspannung 16, insbesondere auf dem unteren Aufnahmeelement 12, auf und zumindest mit einem Teil des Rückens 74 formschlüssig an der Stützvorrichtung 30 an. Die Stützvorrichtung 30 ist von der Kante 34 begrenzt. Im Bereich des Stützelementes 32 liegt der Rücken 74 an der Stützvorrichtung 30 an; im Bereich des Zwischenraumes 36 besteht kein Kontakt zwischen dem Rücken 74 und der Stützvorrichtung 30. Die untere Einspannung 16 weist einen Leerraum 40 auf, der derart ausgebildet und angeordnet ist, dass er zumindest teilweise an den Zwischenraum 36 grenzt. Der Leerraum 40 ist zumindest teilweise durch das untere Aufnahmeelement 12 ausgebildet. Der Leerraum 40 und der Zwischenraum 36 sind derart eingerichtet und angeordnet, dass ein Gegenstand, insbesondere ein Vorrichtungselement wie beispielsweise ein Bereich der Greifvorrichtung 50, in dem Leerraum 40 und dem Zwischenraum 36 auf und ab bewegt werden kann. Auf diese Weise wird ermöglicht, dass ein Bereich der Greifvorrichtung 50, insbesondere ein unterer Greifarm 53, von unten an das Buch 70 herangeführt werden kann und nicht nur im Bereich des Rückens 74 Zugriff zu dem Buch 70 erhält, sondern ebenfalls im Bereich des Deckels 72, mit dem der Leerraum 40 überspannt ist. Dadurch werden ein großflächigerer Zugang zu dem Buch 70 und ein verbessertes und sichereres Greifen ermöglicht, da eine größere Fläche des Buches 70 mit den Greifarmen 52,53 gegriffen werden kann.the Figure 1 4 shows a perspective, partially cut-open representation of a section of a device for performing at least one cutting process 10 according to the present invention, which has a support device 30 for supporting at least one area of a back 74 during the cutting process for producing the book 70. The device 10 comprises a housing 1. A book 70 is placed on the lower clamp 16 in a precisely positioned manner. The lower restraint 16 comprises a lower receiving element 12 which forms a support surface for a book 70. The upper restraint 18, which comprises the upper receiving element 14 and a cutting element, can be moved. It is spaced from book 70. The book 70 rests on the lower restraint 16, in particular on the lower receiving element 12, and at least with part of the back 74 rests in a form-fitting manner on the support device 30. The support device 30 is delimited by the edge 34. In the area of the support element 32, the back 74 rests against the support device 30; There is no contact between the back 74 and the support device 30 in the region of the intermediate space 36. The lower restraint 16 has an empty space 40 which is designed and arranged in such a way that it at least partially borders the intermediate space 36. The empty space 40 is formed at least partially by the lower receiving element 12. The empty space 40 and the intermediate space 36 are set up and arranged in such a way that an object, in particular a device element such as, for example, a region of the gripping device 50, can be moved up and down in the empty space 40 and the intermediate space 36. This enables an area of the gripping device 50, in particular a lower gripping arm 53, to be brought up to the book 70 from below and to gain access to the book 70 not only in the area of the spine 74, but also in the area of the cover 72 , with which the empty space 40 is spanned. This enables a larger area of access to the book 70 and an improved and safer gripping, since a larger area of the book 70 can be gripped with the gripping arms 52, 53.

Ein Teil einer Hubvorrichtung 60 ist perspektivisch teilweise aufgeschnitten dargestellt. Mithilfe der Hubvorrichtung 60 können die Greifarme 52,53 und ein durch sie gegriffenes Buch 70 senkrecht nach oben bewegt werden. Die Hubvorrichtung 60 umfasst eine Hubplatte 68, Schenkel 62 und eine Schiene 63 sowie einen Schubstein 66 und eine Schraubenzugfeder 64. Die Hubvorrichtung 60 befindet sich in ihrer Ausgangsposition, in der sich der Schubstein 66 in seiner Ausgangsposition befindet. Die Schraubenzugfeder 64 ist nicht gedehnt. In der Position der Hubvorrichtung 60 befinden sich der Schenkel 62 sowie die Schiene 63 an der unteren Ebene 42 des Leerraumes 40.Part of a lifting device 60 is shown partially cut away in perspective. With the aid of the lifting device 60, the gripping arms 52, 53 and a book 70 gripped by them can be moved vertically upwards. The lifting device 60 comprises a lifting plate 68, legs 62 and a rail 63 as well as a pusher block 66 and a helical tension spring 64. The lifting device 60 is in its starting position, in which the pusher block 66 is in its starting position. The tension coil spring 64 is not stretched. In the position of the lifting device 60, the leg 62 and the rail 63 are located on the lower level 42 of the empty space 40.

Weiterhin ist in Fig. 1 eine Einführrampe 80 gezeigt. Diese verhindert, dass ein Buch 70, das dem unteren Aufnahmeelement 12 zugeführt wird, mit der unteren Einspannung 16 kollidiert. Die Einführrampe 80 ist am Gehäuse 1, insbesondere an einer unteren Grundplatte der Vorrichtung 10, befestigt. Eine schräge Ebene 82 verläuft von einem darunter liegenden Bereich in Richtung des Stützelementes 32 bis auf die Höhe der Kante 34. Mindestens in dem Bereich, in dem die Hubvorrichtung 60 angeordnet ist, weist die Einführrampe 80 eine Aussparung 84 auf, so dass die Einführrampe 80 mögliche Bewegungen der Hubvorrichtung 60 nicht beeinträchtigt.Furthermore, in Fig. 1 an insertion ramp 80 is shown. This prevents a book 70, which is fed to the lower receiving element 12, from colliding with the lower clamp 16. The insertion ramp 80 is attached to the housing 1, in particular to a lower base plate of the device 10. An inclined plane 82 runs from an area below in the direction of the support element 32 up to the level of the edge 34. At least in the area in which the lifting device 60 is arranged, the insertion ramp 80 has a recess 84 so that the insertion ramp 80 possible movements of the lifting device 60 are not impaired.

In Figur 2 ist ein Ausschnitt einer Vorrichtung zur Durchführung wenigstens eines Schnittvorganges 10 perspektivisch dargestellt. Die Perspektive weicht von der Perspektive der Fig. 1 ab. Ein Buch 70 liegt auf dem unteren Aufnahmeelement 12 auf, an dem eine Stützvorrichtung 30 befestigt ist. Zwischen dem Buch 70 und dem oberen Aufnahmeelement 14 besteht ein Abstand. Mit dem Rücken 74 liegt das Buch 70 bis zur Kante 34 an der Stützvorrichtung 30, insbesondere an den Stützelementen 32, an. Mit den Endbereichen seiner Längsausrichtung ragt der Rücken 74 über die Stützvorrichtung 30 hinaus. Ebenfalls ragt das Buch 70 mit den ungebundenen Begrenzungsseiten 76 über die Begrenzung des unteren Aufnahmeelementes 12 hinaus. In diesem Bereich kann der Beschnitt der ungebundenen Begrenzungsseiten 76 erfolgen. Der Zwischenraum 36 sowie der Leerraum 40 sind dargestellt. Ihre Anordnung ermöglicht, dass zumindest ein Element der Hubvorrichtung 60, aber auch ein Element der Greifvorrichtung 50, im Bereich des Zwischenraumes 36 und des Leerraumes 40 angeordnet und in diesem Bereich an das Buch 70 herangeführt werden kann. In Fig. 2 sind die Schenkel 62 und ein Bereich der Schiene 63 der Hubvorrichtung 60 so angeordnet, dass sie sich innerhalb der Zwischenraumes 36 und des Leerraumes 40 befinden. Sie liegen auf der unteren Ebene 42 auf. Die beiden Schraubenzugfedern 64 sind nicht gedehnt.In Figure 2 a section of a device for performing at least one cutting process 10 is shown in perspective. The perspective differs from the perspective of the Fig. 1 away. A book 70 rests on the lower receiving element 12, to which a support device 30 is attached. There is a clearance between the book 70 and the upper receiving element 14. With the spine 74, the book 70 rests against the support device 30, in particular against the support elements 32, up to the edge 34. With the end regions of its longitudinal alignment, the back 74 protrudes beyond the support device 30. The book 70 with the unbound boundary pages 76 also protrudes beyond the boundary of the lower receiving element 12. The unbound boundary pages 76 can be trimmed in this area. The space 36 and the void 40 are shown. Their arrangement makes it possible that at least one element of the lifting device 60, but also one element of the gripping device 50, can be arranged in the area of the intermediate space 36 and the empty space 40 and can be brought up to the book 70 in this area. In Fig. 2 For example, the legs 62 and a region of the rail 63 of the lifting device 60 are arranged such that they are located within the intermediate space 36 and the empty space 40. They lie on the lower level 42. The two tension coil springs 64 are not stretched.

Die Einführrampe 80 ist mechanisch am Gehäuse 1 und an den Stützelementen 32 befestigt. In Fig. 2 ist veranschaulicht, dass die schräge Ebene 82 und die Aussparung 84 so eingerichtet und angeordnet sind, dass mögliche Bewegungen der Hubvorrichtung 60 nicht durch die Einführrampe 80 beeinträchtigt werden, das bedeutet, dass es zu keinen Kollisionen von Elementen der Hubvorrichtung 60 und der Einführrampe 80 kommen kann. Zudem kann durch die Aussparung 84 ein Gegenstand oder Vorrichtungselement auch derart bewegt werden, dass es weiterhin durch den Zwischenraum 36 und in den Leerraum 40 eingeführt werden kann. Aussparung 84, Zwischenraum 36 und Leerraum 40 sind in einer Flucht angeordnet.The insertion ramp 80 is mechanically attached to the housing 1 and to the support elements 32. In Fig. 2 it is illustrated that the inclined plane 82 and the recess 84 are set up and arranged in such a way that possible movements of the lifting device 60 are not impaired by the insertion ramp 80, which means that there are no Collisions of elements of the lifting device 60 and the insertion ramp 80 can occur. In addition, an object or device element can also be moved through the recess 84 in such a way that it can continue to be introduced through the intermediate space 36 and into the empty space 40. Recess 84, space 36 and empty space 40 are arranged in alignment.

In Fig. 3 ist perspektivisch, teilweise aufgeschnitten ein Ausschnitt der Vorrichtung zur Durchführung wenigstens eines Schnittvorganges 10 dargestellt, die eine Greifvorrichtung 50 umfasst. Es ist ein Ausschnitt der Greifvorrichtung 50 gezeigt. Dieser umfasst einen oberen Greifarm 52 und einen unteren Greifarm 53. Die Greifarme 52,53 weisen Kontaktbereiche 54,55 auf, mit denen die Greifarme 52,53 an ein Buch 70 angelegt werden können. Die Kontaktbereiche 54,55 sind insbesondere aus einem nachgiebigen Material, insbesondere einem Polymer, so dass durch das Anlegen der Kontaktbereiche 54,55 keine Beschädigungen des Buches 70 entstehen. Zudem wird durch das nachgiebige Material ein Gleiten eines gegriffenen Buches 70 zwischen den Greifarmen 52,53 oder aus den Greifarmen 52,53 heraus erschwert bzw. verhindert, da eine Reibungskraft zwischen den Kontaktbereichen 54,55 aus dem nachgiebigen Material und dem Buch 70 wirkt. Die beiden Greifarme 52,53 sind im Wesentlichen parallel zueinander angeordnet, ebenso wie die beiden Kontaktbereiche 54,55. Fig. 3 zeigt eine Vorrichtung zur Durchführung wenigstens eines Schnittvorganges 10, in der ein Buch 70 auf dem unteren Aufnahmeelement 12 aufliegt und der Rücken 74 formschlüssig am Stützelement 32 anliegt. In dieser Position ist das Buch 70 mittels der Greifvorrichtung 50 gegriffen. Dazu sind die Greifarme 52,53, insbesondere die Kontaktbereiche 54,55, an das Buch 70 im Bereich der Deckel 72 angelegt. Der obere Greifarm 52 liegt mit dem oberen Kontaktbereich 54 an dem Deckel 72 an, der sich gegenüber dem unteren Aufnahmeelement 12 befindet. Der untere Greifarm 53, genauer gesagt der untere Kontaktbereich 55, liegt an dem Deckel 72 an, mit dem das Buch 70 auf dem unteren Aufnahmeelement 12 liegt. Damit der untere Kontaktbereich 55 derart an das Buch 70 angelegt werden kann, ist zumindest ein Bereich der Greifvorrichtung 50 innerhalb des Leerraumes 40 und des Zwischenraumes 36 positioniert; insbesondere ein Bereich des unteren Greifarmes 53. Dazu wurde der besagte Bereich durch den Zwischenraum 36 in den Leerraum 40 bewegt sowie in Richtung des Buchdeckels 72. Die Greifvorrichtung 50 ist so angeordnet und eingerichtet, dass Bereiche der Greifvorrichtung 50 durch die Aussparung 84 der Einführrampe 80 bewegt werden können, ohne mit der schrägen Ebene 82 zu kollidieren.In Fig. 3 a section of the device for performing at least one cutting operation 10, which comprises a gripping device 50, is shown in perspective, partially cut open. A section of the gripping device 50 is shown. This comprises an upper gripping arm 52 and a lower gripping arm 53. The gripping arms 52, 53 have contact areas 54, 55 with which the gripping arms 52, 53 can be placed against a book 70. The contact areas 54, 55 are in particular made of a flexible material, in particular a polymer, so that no damage to the book 70 occurs when the contact areas 54, 55 are applied. In addition, sliding of a gripped book 70 between the gripping arms 52, 53 or out of the gripping arms 52, 53 is made difficult or prevented by the flexible material, since a frictional force acts between the contact areas 54, 55 made of the flexible material and the book 70. The two gripping arms 52, 53 are arranged essentially parallel to one another, as are the two contact areas 54, 55. Fig. 3 shows a device for carrying out at least one cutting process 10, in which a book 70 rests on the lower receiving element 12 and the spine 74 rests positively on the support element 32. In this position, the book 70 is gripped by means of the gripping device 50. For this purpose, the gripping arms 52, 53, in particular the contact areas 54, 55, are placed against the book 70 in the area of the cover 72. The upper gripping arm 52 rests with the upper contact area 54 on the cover 72, which is located opposite the lower receiving element 12. The lower gripping arm 53, more precisely the lower contact area 55, rests against the cover 72 with which the book 70 rests on the lower receiving element 12. So that the lower contact area 55 can be applied to the book 70 in this way, at least one area of the gripping device 50 is positioned within the empty space 40 and the intermediate space 36; in particular an area of the lower gripping arm 53. For this purpose, said area was moved through the gap 36 into the empty space 40 and in the direction of the book cover 72 can be moved without colliding with the inclined plane 82.

Wenn das Buch 70 in einem nächsten Arbeitsschritt angehoben werden soll, so dass es nicht mehr auf dem unteren Aufnahmeelement 12 aufliegt, wird dies mithilfe der Hubvorrichtung 60 realisiert. Die Hubplatte 68 und entsprechend die Schenkel 62 und die Schiene 63 werden senkrecht nach oben bewegt. Dies wird erreicht, indem der Schubstein 66 pneumatisch bewegt wird. Der Schubstein 66 weist eine schräge Ebene auf, mit der er an einer komplementären schrägen Ebene der Hubvorrichtung 60 anliegt. Wird der Schubstein 66 verschoben, realisiert er eine Keilwirkung. So wird eine Höhenverschiebung der Teile der Hubvorrichtung 60 bewirkt. Hubplatte 68, Schenkel 62 und Schiene 63 werden senkrecht nach oben bewegt. Die Schraubenzugfeder 64 wird gedehnt. Im Zuge des Greifvorganges wurde die Greifvorrichtung 50 derart bewegt, dass ein Gleitbereich 56 innerhalb der Schiene 63 positioniert ist. Durch diese Positionierung wird eine zusätzliche Stabilität erreicht. Ebenfalls erfindungsgemäß sind Ausführungsformen, in denen ein solcher Gleitbereich 56 nicht eingerichtet ist oder dieser nicht in die Schiene 66 eingeführt wird und Bereiche der Greifvorrichtung 50 oberhalb der Hubplatte 58 positioniert werden. Gemäß der Erfindung soll mithilfe der Hubvorrichtung 60 eine Höhenverschiebung eines Bereiches der Greifvorrichtung 50 vermittelt werden, insbesondere einem Bereich der Greifvorrichtung, der Teile der Greifarme 52,53 umfasst. Durch die Höhenverschiebung der Hubvorrichtung 60 legt sich die Hubplatte 68 bzw. die Schiene 66 zunächst an die entsprechenden Bereiche der Greifvorrichtung 50 an und drückt diese im Weiteren nach oben. Derart hat eine Höhenverschiebung der Hubvorrichtung 60 eine Höhenverschiebung zumindest von Teilen der Greifvorrichtung 50 zur Folge. Insbesondere werden so die Greifarme 52,53 und das gegriffene Buch 70 angehoben. Vorteilhaft wird der Schubstein 66 so weit bewegt, dass die Greifarme 52,53 derart senkrecht nach oben verschoben werden, dass in einem nächsten Schritt das Buch 70 über die Kante 34 hinweg bewegt werden kann, ohne mit der Stützvorrichtung 30 zu kollidieren.If the book 70 is to be lifted in a next work step so that it no longer rests on the lower receiving element 12, this is implemented with the aid of the lifting device 60. The lifting plate 68 and, accordingly, the legs 62 and the rail 63 are moved vertically upwards. This is achieved by using the push stone 66 is moved pneumatically. The pusher block 66 has an inclined plane with which it rests on a complementary inclined plane of the lifting device 60. If the pusher block 66 is moved, it realizes a wedge effect. In this way, the parts of the lifting device 60 are shifted in height. Lifting plate 68, legs 62 and rail 63 are moved vertically upwards. The tension coil spring 64 is stretched. In the course of the gripping process, the gripping device 50 was moved in such a way that a sliding area 56 is positioned within the rail 63. This positioning provides additional stability. Also according to the invention are embodiments in which such a sliding area 56 is not set up or this is not inserted into the rail 66 and areas of the gripping device 50 are positioned above the lifting plate 58. According to the invention, a height displacement of an area of the gripping device 50 is to be conveyed with the aid of the lifting device 60, in particular an area of the gripping device which comprises parts of the gripping arms 52, 53. As a result of the height displacement of the lifting device 60, the lifting plate 68 or the rail 66 first rests against the corresponding areas of the gripping device 50 and then pushes them upwards. In this way, a height displacement of the lifting device 60 results in a height displacement of at least parts of the gripping device 50. In particular, the gripping arms 52, 53 and the gripped book 70 are raised in this way. The pusher block 66 is advantageously moved so far that the gripping arms 52, 53 are displaced vertically upwards in such a way that in a next step the book 70 can be moved over the edge 34 without colliding with the support device 30.
