Description

Die vorliegende Erfindung betrifft ein Verfahren sowie eine Vorrichtung zum Beschneiden von Druckprodukten nach dem Oberbegriff des Anspruchs 1 bzw. des Anspruchs 13.The present invention relates to a method and a device for trimming of printed products according to the preamble of claim 1 and of claim 13.

Für das Beschneiden von Druckprodukten, insbesondere gebundene Buchblocks, Broschuren u. dgl., sind Dreimesserschneidemaschinen bekannt, welche die Druckprodukte an den drei nicht gebundenen Seiten beschneiden, wobei die Druckprodukte von einem Pressstempel auf einem stationären Schneidtisch fixiert werden und Seitenmesser die Kopf- und Fußseite und ein Quermesser die Vorderseite nacheinander beschneiden. Die Schnitte werden im Schrägschwingschnitt gegen eine Schneidleiste ausgeführt, welches auch als Messerschnittprinzip am stehenden Produkt bekannt ist und qualitativ hochwertige Schnitte auch bei dicken Druckprodukten gestattet. Die DE 28 52 878 C2 zeigt eine Dreimesserschneidemaschine mit hypozykloidischen Bewegungen der Seitenmesser, wodurch eine nahezu gleichzeitige Seitenmesser- und Quermesserbewegung für das Beschneiden ermöglicht wird.For trimming printed products, especially bound book blocks, brochures u. Like., Dreimesserschneidemaschinen are known which the printed products at the three unbound pages, the printed products of a Press punches are fixed on a stationary cutting table and side knife the Head and foot side and a transverse knife cut the front one after the other. The Sections are performed in a diagonal cutting against a cutting bar, which Also known as knife cutting principle on standing product and high quality Sections are allowed even with thick printed products. DE 28 52 878 C2 shows a Three-knife cutting machine with hypocycloidal movements of the side knives, whereby an almost simultaneous side knife and cross knife movement for trimming is possible.

Durch das Ausführen aller Schnitte in einer Pressstellung werden Verschiebungen der Druckprodukte durch Zwischenentlastung bzw. Transport vermieden und eine hohe Maßhaltigkeit erreicht. Aufgrund des Produktstillstandes beim Beschnitt einhergehend mit einer Zuführung, Ausrichtung, Pressung und Ausführung der Druckprodukte ist die Taktzahl bei Dreimesserschneidemaschinen begrenzt. Höhere Schneidleistungen, wie sie in Klebebinderfließstrecken verlangt werden, werden durch Stapelbildung bewältigt - mit nicht unerheblichem Aufwand für das Stapeln und ggf. das Entstapeln, wenn nach dem Dreiseitenbeschnitt Einzelprodukte zu verarbeiten sind. Wegen formatabhängiger Wechselteile (Schneidtisch, Pressstempel) wird bei einem Formatwechsel eine Rüstzeit erforderlich.By performing all cuts in a press position shifts of Printed products avoided by intermediate relief or transport and a high dimensional stability reached. Due to the product standstill when trimming along with a Feeding, alignment, pressing and execution of the printed products is the number of cycles limited to three knife cutting machines. Higher cutting performance, as in Klebebinderfließstrecken be required are managed by stacking - not with Insignificant effort for stacking and possibly unstacking, if after the three-side trimming Individual products are to be processed. Because of format-dependent change parts (Cutting table, press punch) a set-up time is required when changing the format.

Für die Realisierung des Dreiseitenbeschnitts sind außerdem Trimmer bekannt, die nach dem Scherschnittprinzip arbeiten, welches dadurch gekennzeichnet ist, dass ein Obermesser gegen ein feststehendes Untermesser bewegt wird. Seiten- und Frontbeschnitt werden in zwei, räumlich voneinander getrennten Stationen ausgeführt. Es sind nur eingeschränkte Schnittqualitäten erreichbar und die maximale Einsatzhöhe ist auf ca. 15 mm begrenzt. Trimmer eignen sich für den Einzelbeschnitt von Zeitschriften und dünnen Broschuren und erreichen hohe Schneidleistungen.For the realization of the three-side trimming trimmers are also known that after working the shear cut principle, which is characterized in that an upper blade is moved against a fixed lower blade. Side and front trim are executed in two, spatially separated stations. They are only limited Cutting quality achievable and the maximum insertion height is about 15 mm limited. Trimmers are suitable for single cutting of magazines and thin brochures and achieve high cutting performance.

Das Scherschnittprinzip wird auch genutzt bei Rotationsschneidern, in denen die Druckprodukte im Schuppenstrom zwei Schneidstationen durchlaufen, welche in rechtwinkliger Anordnung zueinander durch ein Eckmodul zur Umorientierung der Druckprodukte gekoppelt sind. Die Schnitte erfolgen hierbei durch rotierender Obermesser, die sich gegen ebenfalls rotierende Untermesser bewegen. Die zu beschneidenden Druckprodukte werden, von Pressbändern gehalten, durch die Schneidstationen gefördert. Mit Rotationsschneidem werden höchste Schneidleistungen ermöglicht. Sie sind aber wegen des Scherschnittprinzips mit Rotationsmessem für den qualitativen Dreiseitenbeschnitt nicht geeignet.The shear cut principle is also used in rotary cutters, in which the printed products in the scale flow through two cutting stations, which in rectangular Arrangement coupled to each other by a corner module for reorientation of the printed products are. The cuts are made by rotating upper blade, which oppose also move rotating undercutter. The printed products to be cut are held by press belts, conveyed by the cutting stations. With rotary cutting highest cutting performance is possible. But they are because of the Shear cut principle with rotary knife for the qualitative three-side trimming not suitable.

Ein weiteres Prinzip zum Beschneiden von Druckprodukten ergibt sich aus dem Messerschnittverfahren mit stillstehend angeordnetem Messer, gegen das die Druckprodukte eingespannt gehalten bewegt werden. Aus der EP 0 670 203 B1 ist eine Vorrichtung bekannt, bei der zur Herabsetzung der nicht unerheblichen Schnittkräfte eine Vielzahl von nacheinander auf die zu beschneidende Kante des Druckprodukts einwirkende Schneiden vorgesehen ist. Die Größe der notwendigen Haltekräfte erfordert aber weiterhin das Einspannen der Druckprodukte in einem Klammerwagen, wodurch bei dieser Vorrichtung eine getaktete Zu- und Ausführung der Druckprodukte unumgänglich ist.Another principle for trimming printed products results from the knife cutting process with stationary knife, against which the printed products be kept in a clamped position. From EP 0 670 203 B1 a device is known, in the reduction of the not inconsiderable cutting forces a variety of one after the other on the edges of the printed product to be trimmed cutting is provided. The size of the necessary holding forces but still requires the Clamping the printed products in a stapler, resulting in this device a timed delivery and execution of the printed products is essential.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Beschneiden von Druckprodukten gemäß dem Oberbegriff des Anspruchs 1 und eine Vorrichtung für dessen Durchführung zu schaffen, die es gestatten, ungetaktet zugeführte Einzelprodukte bei hohen Schneidleistungen qualitativ hochwertig zu beschneiden.The present invention is based on the object, a method for trimming of printed products according to the preamble of claim 1 and a device for to provide for its implementation, which allows uncalibrated individual products to be supplied High quality cutting at high cutting performance.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Schneidvorgang in zwei aufeinander folgenden Arbeitsgängen erfolgt, wobei die zu beschneidende Seite der Druckprodukte in einem ersten Arbeitsgang durch einen Vorbeschnitt bis nahe dem endgültigen Beschnittmaß abgetrennt und in einem zweiten Arbeitsgang durch einen Glättungs- bzw. Endbeschnitt mittels des ziehenden Messerschnitts endbeschnitten wird. Es hat sich dabei als besonders vorteilhaft gezeigt, den Vorbeschnitt mit einem rotierenden Werkzeug auszuführen, wobei die zu beschneidende Seite tunlichst spanend, z.B. durch Fräsen oder Sägen, bearbeitet wird, und beim Glättungs- bzw. Endbeschnitt nur noch einen sehr dünnen Schnittspan von vorzugsweise ca. 0,5 mm Dicke abzuschneiden.This object is achieved in that the cutting process in two successive operations, with the page to be trimmed Printed products in a first pass through a pre-cut to near the final Trimming cut off and in a second operation by a smoothing End trim is cut by means of the drawing knife cut. It has shown to be particularly advantageous, the pre-cropping with a rotating Implement tool, with the side to be trimmed as far as possible, e.g. by Milling or sawing, is processed, and when smoothing or final trimming only cut a very thin Schnittpan of preferably about 0.5 mm thickness.

Die Erfindungsidee liegt nämlich darin, die Druckprodukte mit einem Trennverfahren zunächst vorzuschneiden, das unabhängig vom Beschnittmaß nur geringe Schnittkräfte aufweist, um sie dann mit dem ziehenden Messerschnitt durch Abtrennen eines dünnen Schnittspans glatt zu schneiden. Weil dabei nur ein geringes Papiervolumen zur Seite gedrängt werden muss, werden nur geringe Schnittkräfte benötigt, die außerdem weitestgehend unabhängig von der relativen Ziehgeschwindigkeit des Messers sind und mit größerer Produktdicke nur unwesentlich ansteigen. Das Schneidverfahren eignet sich daher auch für den Beschnitt dicker Druckprodukte und ermöglicht hohe Schneidleistungen.The idea of the invention lies in the fact that the printed products are first subjected to a separation process to cut to size, regardless of the trim size only low cutting forces to then pull them with the pulling knife cut by separating a thin Smooth cutting cuts. Because it only a small volume of paper to the side must be urged, only low cutting forces are needed, which also largely regardless of the relative pulling speed of the knife are larger and with Product thickness increase only insignificantly. The cutting method is therefore suitable also for trimming thick printed products and enables high cutting performance.

Zweckmäßig ist der ständig gehaltene Transport der Druckprodukte während des Schneidvorgangs mit Vorbeschnitt und Glättungs- bzw. Endbeschnitt. Aufgrund der im Verhältnis zu den vorbekannten Schneidverfahren geringen Schnittkräfte genügt es gemäß einer bevorzugten Ausführungsform, die Druckprodukte zur Förderung beim Schneidvorgang zwischen endlosen Transportmitteln, wie Pressband, Rollenkette mit Klemmplatten, Zahnriemen o. dgl., einzuspannen. Zusätzliche Klemmmittel, wie synchron mitbewegte Presstempel und Schneidtische, sind nicht erforderlich, wodurch bei einem Formatwechsel keine formatabhängigen Wechselteile ausgetauscht werden müssen. Das Schneidverfahren zeichnet sich gemäß Unteranspruch 8 dadurch aus, dass die Druckprodukte ungetaktet gegen die Schneidwerkzeuge bewegbar sind. Mit Vorteil ist das Schneidverfahren auch einsetzbar für den Beschnitt von im Schuppenstrom geförderten Druckprodukten.Appropriately, the constantly held transport of the printed products during the Cutting process with pre-cutting and smoothing or final trimming. Because of the Relative to the previously known cutting methods low cutting forces, it is sufficient in accordance a preferred embodiment, the printed products to promote the Cutting process between endless means of transport, such as press belt, roller chain with Clamp plates, timing belt o. The like., To clamp. Additional clamping means, like synchronous mitbewegte press ram and cutting tables, are not required, which at one Format change no format-dependent change parts must be replaced. The Cutting process is characterized according to dependent claim 8 characterized in that the printed products untimed against the cutting tools are movable. That's an advantage Cutting method can also be used for trimming of shingled material Printed products.

Anspruch 10 gibt an, dass das erfindungsgemäße Schneidverfahren für den Dreiseitenbeschnitt genutzt werden kann. Im Anspruch 11 ist die Anwendung des Schneidverfahrens für die Rückenbearbeitung von Buchblocks beim Klebebinden angegeben, wobei mit dem Schneidverfahren der Bundsteg der zusammengetragenen Falzbogen abgetrennt wird. Gemäß Anspruch 12 folgt dem Abtrennen das Aufrauhen und Kerben des Buchblockrückens.Claim 10 indicates that the cutting method according to the invention for the three-side trimming can be used. In claim 11, the application of the cutting process specified for the back processing of book blocks in adhesive binding, with the cutting process of the gutter of the gathered signatures separated becomes. According to claim 12, the severing is followed by roughening and scoring of the book block spine.

Die Vorrichtung zur Durchführung des Schneidverfahrens weist gemäß Anspruch 13 ein Schneidmodul auf, das aus einer ersten, ein rotierend angetriebenes Schneidwerkzeug umfassenden Schneidstation zum Vorbeschneiden und einer zweiten, ein stehendes Messer umfassenden Schneidstation zum glatten Endbeschneiden besteht. Bevorzugte Ausbildungsformen der Vorrichtung sind in den weiteren abhängigen Ansprüchen angegeben.The apparatus for performing the cutting method has according to claim 13 Cutting module, which consists of a first, a rotating driven cutting tool comprehensive cutting station for pre-cutting and a second, a standing Knife comprehensive cutting station for smooth end trimming exists. preferred Embodiments of the device are indicated in the further dependent claims.

Die Buchblocks 2 weisen je eine Kopfseite 3, eine Fußseite 4, einen Rücken 5 und eine Vorderseite 6 auf und sind im Rücken 5 gebunden. Die unbeschnittenen Buchblocks 2a haben eine Höhe H u und eine Breite B u . Nach dem dreiseitigen Beschneiden an den drei nicht gebundenen Seiten, nämlich der Kopf- 3, Fuß- 4 und Vorderseite 5, ergibt sich die Höhe H und die Breite B am endbeschnittenen Buchblock 2b.The book blocks 2 each have a head side 3, a foot side 4, a back 5 and a front side 6 and are bound in the back 5. The uncut book blocks 2a have a height H u and a width B u . After the three-sided trimming on the three unbound pages, namely the head 3, foot 4 and front 5, the height H and the width B results at the end-trimmed book block 2b.

Für den Frontbeschnitt werden die unbeschnittenen Buchblocks 2a auf einem Transportband 7 unter Ausrichtung an seitlichen Führungen 8a,b der Schneideinheit S1 mit einer Fördergeschwindigkeit v 1 zugeführt und nahe der gewünschten Schneidkante durch die Pressplattenkettenförderer 10, 11 eingespannt weitergefördert. Der nicht eingespannte Teil der Buchblocks 2 wird von Stützschienen 12 getragen. Die Buchblocks 2 gelangen mit ihrer unbeschnittenen Vorderseite 6a in den Wirkbereich des von einem Motor 14 rotierend angetriebenen Sägeblatts 15, wobei zur Schaffung einer ebenen Seitenfläche wenigstens der zerklüftete Abschnitt vom Buchblock 2 abgetrennt wird. Unter Beibehaltung der eingespannten Förderung werden die Buchblocks 2 dann mit ihrer vorbeschnittenen Vorderseite 6b dem unter einem Schneidwinkel α feststehend angeordneten Messer 17 zugeführt zur Durchführung des glatten Endbeschnitts. Gemäß der Erfindungsidee wird nur ein dünner Schnittspann von ca. t = 0,5 mm Dicke abgeschnitten. Damit auch das letzte Blatt sicher abgeschnitten wird, ist das Messer 17 gegen eine in einem Halter 19 freidrehend gelagerte Stützrolle 18 angestellt.For the front trimming, the uncut book blocks 2a are conveyed on a conveyor belt 7 aligned with lateral guides 8a, b of the cutting unit S1 at a conveying speed v 1 and conveyed close to the desired cutting edge by the press plate chain conveyors 10, 11. The unclamped part of the book block 2 is supported by support rails 12. The book blocks 2 reach with their uncut front side 6a into the effective range of a motor 14 rotatably driven saw blade 15, wherein to create a flat side surface of at least the fissured portion of the book block 2 is separated. While maintaining the clamped promotion, the book blocks 2 are then supplied with their pre-cut front side 6b at a cutting angle α fixedly arranged knife 17 for performing the smooth Endbeschnitts. According to the idea of the invention, only a thin section of approximately t = 0.5 mm thickness is cut off. Thus, the last sheet is cut off safely, the knife 17 is employed against a free-rotating in a holder 19 support roller 18.

Die Buchblocks 2 mit der endbeschnittenen Vorderseite 6c werden an ein Transportband 20 abgegeben und über ein Eckmodul 21, bestehend aus einem Saugbandförderer 22 und einer Anschlagschiene 23, quer zur ursprünglichen Förderrichtung mit einer Fördergeschwindigkeit v 2 weitergefördert zur Übergabe an ein die Buchblocks 2 mit Führungsschienen 25a,b seitlich ausrichtendes und der zweiten Schneideinheit S2 zuführendes Transportband 24.The book blocks 2 with the end-trimmed front side 6c are delivered to a conveyor belt 20 and conveyed via a corner module 21, consisting of a suction belt conveyor 22 and a stop rail 23, transversely to the original conveying direction with a conveying speed v 2 for transfer to a book block 2 with guide rails 25a , b laterally aligning and the second cutting unit S2 feeding conveyor belt 24th

In der zweiten Schneideinheit S2 werden die Buchblocks 2 jeweils entlang der Kopf- 3 und der Fußseite 4 von Pressplattenkettenförderern 10, 11 eingespannt weitergefördert. Die Schneidvorgänge für den Kopf- und den Fußbeschnitt werden wie beim Frontbeschnitt durchgeführt. In Fig. 3 erkennt man, wie die zerklüftete unbeschnittene Kopfseite 3a vom Sägeblatt 15 in der Vorbeschnittstation 13 abgetrennt und die vorbeschnittene Fußseite 4a durch das feststehende Messer 17 in der Endbeschnittstation 16 endbeschnitten wird. Beim Transport durch die Schneideinheit S2 werden die Buchblocks 2 durch eine mittig zwischen den Pressplattenkettenförderem 10,11 liegende Stützschiene 28 unterstützt. Nach dem Beschneiden in der Schneideinheit S2 werden die fertig beschnittenen Buchblocks 2a an ein Transportband 29 übergeben und weiterverarbeitenden Einrichtungen zugeführt.In the second cutting unit S2, the book blocks 2 are respectively along the head 3 and the foot 4 further conveyed by press plate chain conveyors 10, 11 clamped. The cutting operations for the head and foot trim are the same as for the front trim carried out. In Fig. 3 can be seen how the ragged uncut side of the head 3a separated from the saw blade 15 in the Vorbeschnittstation 13 and the pre-cropped Foot side 4a end-cut by the fixed blade 17 in the Endbeschnittstation 16 becomes. During transport through the cutting unit S2, the book blocks 2 by a support rail located centrally between the press plate chain conveyors 10,11 28 supported. After trimming in the cutting unit S2, the finished trimmed Book blocks 2a passed to a conveyor belt 29 and further processing Supplied facilities.

In Fig. 3 ist außerdem der Aufbau der Pressplattenkettenförderer 10, 11 erkennbar. Der untere Pressplattenkettenförderer 10 wird gebildet aus einer um Kettenräder 40 umlaufend, angetriebenen Rollenkette 30, die sich im Bereich des geklemmten Transports auf einer an einem gestellfesten Halter 38 befestigten Kettenführung 39 abstützt. An den einzelnen Gliedern der Rollenkette 30 sind Bügel 32 befestigt, die die Aufnahme von Pressplatten 33 ermöglichen. Die Buchblocks 2 liegen auf den Pressplatten 33 des unteren Pressplattenkettenförderers 10 auf und werden durch die Pressplatten 33 des ähnlich aufgebauten oberen Pressplattenkettenförderers 11 mit einer definierten Haltekraft eingespannt. Zur Erzeugung der Haltekraft ist die zugeordnete Kettenführung 34 zwischen Führungsplatten 36 geführt und über Druckfedern 35 gegen einen gestellfest angeordneten Halter 37 abgestützt. Hierdurch wird die Rollenkette 30 mit den zugehörigen Pressplatten 33 nach unten gedrückt, wobei der Verschiebeweg durch vorstehende Bolzen 31 der Rollenkette 30 in entsprechend ausgeführten Nuten 36a der Führungsplatten 36 begrenzt ist. In Fig. 3 also the structure of the press plate chain conveyors 10, 11 can be seen. Of the lower press plate chain conveyor 10 is formed from a circulating around sprockets 40, driven roller chain 30, located in the area of the clamped transport on a fixed to a frame-fixed holder 38 chain guide 39 is supported. At the individual Links of the roller chain 30 are fixed bracket 32, which includes the inclusion of press plates 33 allow. The book blocks 2 are located on the press plates 33 of the lower Press plate chain conveyor 10 and are similar by the pressing plates 33 of the built-up upper press plate chain conveyor 11 clamped with a defined holding force. To generate the holding force is the associated chain guide 34 between guide plates 36 guided and arranged by pressure springs 35 against a frame fixed Holder 37 supported. As a result, the roller chain 30 with the associated press plates 33 pushed down, wherein the displacement by projecting bolts 31 of Roller chain 30 limited in correspondingly executed grooves 36a of the guide plates 36 is.

Die oberen Pressplattenkettenförderer 11 sind durch nicht näher dargestellte Mittel bezüglich der Dicke D der Buchblocks 2 verstellbar. In den Fig. 2 und 3 ist diese Verstellung V D durch einen gestrichelten Doppelpfeil symbolisiert. Weitere Verstellungen sind vorgesehen zur Berücksichtigung der Breite B und der Höhe H der Buchblocks 2. So wird in der Schneideinheit S1 das Schneidmodul 9 mit der Verstellung V B bezüglich der Breite B verstellt derart, dass der Rücken 5 an einer konstanten Linie geführt wird. In der Schneideinheit S2 wird das Schneidmodul 27 für den Fußbeschnitt hinsichtlich der Höhe H der Buchblocks 2 verstellt. Diese Verstellung V H ist auch für die Anschlagschiene 23 des Eckmoduls 21 vorgesehen.The upper press plate chain conveyor 11 are adjustable by means not shown with respect to the thickness D of the book block 2. In FIGS. 2 and 3, this adjustment V D is symbolized by a dashed double arrow. Further adjustments are provided to take account of the width B and the height H of the book block 2. Thus, in the cutting unit S1, the cutting module 9 is adjusted with the adjustment V B with respect to the width B such that the back 5 is guided on a constant line. In the cutting unit S2, the cutting module 27 for Fußbeschnitt is adjusted in terms of the height H of the book block 2. This adjustment V H is also provided for the stop rail 23 of the corner module 21.

Der nach dem erfindungsgemäßen Schneidverfahren ausgeführte Dreischneider 1 für Buchblocks 2 erfordert keine getakteten Produktströme, wodurch eine kostengünstige Konstruktion ermöglicht wird, insbesondere auch weil gleichartig aufgebaute Schneidmodule 9, 26, 27 zum Einsatz kommen. Neben hohen Schneidleistungen zeichnet sich der Dreischneider 1 dadurch aus, dass auch größere (Produkt-) Dicken D verarbeitbar sind. Die Schneideinheiten S1, S2 können alternativ zur dargestellten Ausführung an verschiedenen Orten bzw. in unterschiedlichen Phasen der Druckweiterverarbeitung eingesetzt werden. So könnte die Schneideinheit S1 unmittelbar hinter einem Klebebinder eingesetzt werden, wobei ein stehender Transport der Buchblocks (2) wie im Klebebinder denkbar ist. Die Schneideinheit S2 würde erst im Anschluss an eine Transporttrockenstrecke folgen. Das Schneidverfahren kann außerdem auch im Klebebinder selbst für den Frontbeschnitt (9) verwirklicht werden, indem die in Transportklammem eingespannt geförderten Buchblocks (2) zunächst an einem Sägeblatt (15) oder an Fräswerkzeugen für den Vorbeschnitt (13) und anschließend an einem stehenden Messer (17) für den Endbeschnitt (16) vorbeigeführt werden. The executed according to the cutting method according to the invention three trimmer 1 for book block 2 does not require pulsed product streams, whereby a cost-effective design is made possible, especially because similarly constructed cutting modules 9, 26, 27 are used. In addition to high cutting performance, the three-knife trimmer 1 is characterized by the fact that even larger (product) thicknesses D can be processed. The cutting units S1, S2 can be used as an alternative to the illustrated embodiment at different locations or in different phases of the print finishing. Thus, the cutting unit S1 could be used immediately behind an adhesive binder, wherein a stationary transport of the book block (2) as in the perfect binder is conceivable. The cutting unit S2 would follow only after a transport dry stretch. The cutting method can also be realized in the adhesive binder itself for the front trimming (9) by the supported in Transportklammem funded book block (2) first on a saw blade (15) or on milling tools for Vorbeschnitt (13) and then on a stationary knife ( 17) for the Endbeschnitt (16) are passed.
