Description

Die Erfindung betrifft eine Vorrichtung zum Beschneiden von Bogen, Bogenstapeln, Broschüren und dgl. an Fertigungslinien zur buchbin­ derischen Weiterverarbeitung von polygraphischen Erzeugnissen.The invention relates to a device for trimming sheets, Sheet stacks, brochures and the like on production lines for the book further processing of polygraphic products.

Mit der CH-PS 5 61 593 ist ein Verfahren zum Zuschneiden eines Stapels von Bogen sowie die Einrichtung zur Durchführung des Verfahrens bekanntgeworden. Mit diesem Verfahren ist es möglich, lediglich jeweils einen Stapel unbeschnittener Bogen auf zwei in Förderrichtung hintereinander angeordneten Schneidstationen in der Weise von drei Seiten zuzuschneiden, daß mit der Messervorrich­ tung der ersten Schneidstation dessen Stirnseite sowie mit den beiden Messervorrichtungen der zweiten Schneidstation dessen Kopf- und Fußseiten beschnitten werden. Des weiteren ist es zwar mög­ lich, bei Anwendung des Doppelnutzenprinzips den Stapel auch noch mittels einer in der Mitte der Bogenförderbahn angeordneten Mes­ sereinrichtung zu trennen. Bei Einsatz eines Stanzmessers ist die Bearbeitung von nur dünnen Bogenstapeln bis etwa 4 mm in guter Qualität möglich. Sollen dagegen dickere Bogenstapel, wie z. B. Broschuren mit einer Dicke von über 4 mm, im Doppelnutzenprinzip verarbeitet werden, erfolgt die Trennung des Stapels in der zwei­ ten Schneidstation durch das erste mittlere Messer, wodurch ein Nutzen fertiggestellt ist, jedoch muß das Beschneiden des zweiten Nutzens in einer zusätzlichen dritten Schneidstation vonstatten gehen. Mithin ist diese Einrichtung zum Beschneiden von Broschu­ ren, insbesondere auch Rückstichbroschuren, nicht geeignet.CH-PS 5 61 593 is a method for cutting a Stack of sheets as well as the device for carrying out the Process became known. With this procedure it is possible only one stack of untrimmed sheets at a time in two Conveying stations arranged one behind the other in the Cut from three sides, that with the knife tion of the first cutting station, its end face and with the two knife devices of the second cutting station whose head and the sides of the foot are trimmed. Furthermore, it is possible Lich, the stack also when using the dual-use principle by means of a measuring device arranged in the middle of the sheet conveying path to separate water equipment. When using a punch knife, the Processing of only thin sheet stacks up to about 4 mm in good Quality possible. On the other hand, thicker stacks of sheets, such as. B. Brochures with a thickness of over 4 mm, based on the double-use principle processed, the stack is separated into two cutting station through the first middle knife, creating a Benefit is finished, however, the pruning of the second Benefit in an additional third cutting station go. So this device is for trimming brochure Ren, especially backstitch brochures, not suitable.

Ziel der Erfindung ist es, eine Vorrichtung zu schaffen, mit der das Beschneiden von weiterzuverarbeitenden Produkten, insbesondere von Bogenstapeln oder Broschuren, in hoher Qualität bei gleichzei­ tiger Steigerung der Produktivität gesichert ist.The aim of the invention is to provide a device with which the trimming of products to be processed, in particular sheet stacks or brochures, in high quality at the same time increased productivity is assured.

Der Erfindung liegt darum die Aufgbe zugrunde, die Anordnung der Messer in der Vorrichtung derart vorzunehmen, daß der Beschnitt von gleichzeitig zwei Produkten in nur zwei Schneidstationen er­ folgen kann. The invention is therefore based on the task, the arrangement of the Make knife in the device so that the trimming of two products at the same time in only two cutting stations can follow.  

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß in der ersten Schneidstation der Vorrichtung ein über die Breite zweier Produk­ tenströme reichendes Vorderbeschnittmesser angeordnet und daß in der zweiten äußere Messer, an einem gemeinsamen Messer­ träger befestigt sind und daß alle doppelt angeordneten Förder- und Ausrichtelemente beider Produktenströme in jeder Schneidsta­ tion eine Funktionseinheit bilden. Dabei ist in der zweiten Schneidstation eine Messeranordnung derart möglich, daß entweder die inneren Messer einen konstanten Abstand zueinander aufweisen sowie ortsunveränderlich und daß die äußeren Messer formatabhängig verstellbar angeordnet sind oder daß jeweils ein äußeres und ein inneres Messer zueinander formatabhängig verstellbar angeordnet sind. Möglich ist es auch, die inneren Messer der zweiten Schneid­ station herausnehmbar oder gegen eine Stanzvorrichtung austausch­ bar anzuordnen. Mit der erfindungsgemäßen Vorrichtung wird bei jeder Ausführung der Vorgang der Formateinstellung optimal verein­ facht. Des weiteren erfolgt der Beschnitt der zu beschneidenden Kanten der Produkte nach dem Scherenprinzip, also der Funktion von Obermessern gegen Untermesser, wodurch mit der Vorrichtung ein qualitativ hochwertiger Beschnitt der Produkte unabhängig von ihrer Dicke gewährleistet ist, wobei die Produktivität beim Dop­ pelstromprinzip auf das Doppelte erhöht wird. Darüber hinaus ist es möglich, durch den Austausch der inneren Messer der zweiten Schneidstation gegen eine Stanzeinrichtung geeignete Produkte auch nach dem an sich bekannten Doppelnutzenprinzip zu bearbeiten, also eine bisher noch nicht bekannte Universalität zu erreichen. Diese Universalität ist noch durch das ledigliche Herausnehmen der inne­ ren Messer erweiterbar, weil dadurch ein mittiger Beschnitt auch von Einzelexemplaren erfolgen kann.According to the invention the object is achieved in that in the first Cutting station of the device across the width of two products arranged front trimming knife and that in the second outer knife, on a common knife are fixed and that all double arranged conveyor and alignment elements of both product streams in each cutting station tion form a functional unit. It is in the second Cutting station a knife arrangement possible so that either the inner knives are at a constant distance from each other as well as stationary and that the outer knives depend on the format are adjustable or that each have an outer and a inner knife adjustable to each other depending on the format are. It is also possible to cut the inner knife of the second Removable station or exchange for a punching device to be arranged in cash. With the device according to the invention each execution optimally combine the process of setting the format fold. Furthermore, the pruning is trimmed Edges of the products according to the scissors principle, i.e. the function of Upper knives against lower knives, which means with the device high quality trimming of the products regardless of their thickness is guaranteed, while productivity in dop principle is doubled. Beyond that it is possible by replacing the inner knife of the second Cutting station against a punching device also suitable products to process according to the known double benefit principle, so to achieve a hitherto unknown universality. These Universality is still only by removing the inside Ren knife can be expanded because this also means a central trim can be made from individual copies.
