Description

Die Erfindung betrifft eine Einrichtung für das Beschneiden wenigstens einer Seitenkante gebundener resp. gehefteter Druckerzeugnisse, wie beispielweise Buchblocks, Bücher, Zeitschriften oder dgl., bestehend aus einem Schneidtisch, dem die Druckerzeugnisse jeweils in eine Schneidposition versetzbar flach aufliegend zuführbar sind, und einem die Druckerzeugnisse zumindest während dem Schneidvorgang gegen den Schneidtisch pressenden, auf ein Druckerzeugnis absenk- und von diesem anhebbaren Pressstempel sowie wenigstens einem aus einer Ausgangsstellung gegen den Schneidtisch und zurück angetriebenen Schneidmesser und einer die Schneidbewegung begrenzenden Schneidleiste oder einem Gegenmesser, wobei der Pressstempel einen den Druckerzeugnissen im Näherungsbereich der Seitenkante zugewandten, in Pressrichtung an dem Pressstempel erhöhten Pressrand aufweist, der einen dem Schneidtisch zugewandten Expansionsraum bildet, welcher zur Aufnahme einer elastischen Einlage ausgebildet ist.The invention relates to a device for trimming at least one side edge bound resp. Stapled printed products, such as book blocks, books, magazines or the like., Consisting of a cutting table, the print products are displaceable in a cutting position displaceable flat fed, and a the press products at least during the cutting process against the cutting table pressing, on a printed matter sinkenk- and from this liftable ram and at least one of a starting position against the cutting table and driven back cutting blade and a cutting movement limiting cutting bar or a counter knife, the ram having a printed products in the proximity of the side edge facing, in the pressing direction on the ram raised pressing edge, the forms an expansion space facing the cutting table, which is designed to receive an elastic insert.

Einrichtungen der genannten Art sind für den Beschnitt der drei Seitenkanten gebundener Druckerzeugnisse vorgesehen und dem Fachmann als Dreischneider, Trimmer, Dreimesserautomat oder ähnlichen Bezeichnungen bekannt. Die gebundenen Druckerzeugnisse werden in einem seriellen Produktestrom, einzeln oder in Stapeln einem Schneidtisch zugeführt und dabei nach dem Rücken und/oder den Seitenkanten ausgerichtet, danach mittels eines Pressstempels auf den Schneidtisch gepresst und in dieser Position beschnitten. Die Messer führen hierzu jeweils eine gegen eine am Schneidtisch befestigte Schneidleiste gerichtete Schneidbewegung aus. Nach diesem Prinzip arbeitende Dreischneider gewährleisten eine gute Qualität der Druckerzeugnisse in Bezug auf die Geometrie und die Schnittfläche. Nachteilig ist, dass für die Umstellung auf verschiedene Formate in der Regel sowohl der Pressstempel, als auch der Schneidtisch entsprechend dem Format ausgetauscht werden müssen. Enthalten die Druckerzeugnisse zusätzlich Beilagen, wie Beutel, Warenmuster, Hefte oder dgl. Produkte, kann die Dicke innerhalb der Druckerzeugnisse variieren. Um die Presskraft in die Bereiche der Seitenkanten verteilen zu können, muss nach dem Stand der Technik die Topologie des Pressstempels an die Oberflächentopologie der Druckerzeugnisse angepasst werden. Diese Anpassarbeiten können erst nach dem Vorhandensein der gebundenen Druckerzeugnisse vorgenommen werden, wodurch die restlichen, bereits eingerichteten Anlageteile solange nicht produzieren können, bis auch der Dreischneider eingerichtet ist. Die Umstellzeit des Dreischneiders beeinträchtigt somit die Effizienz einer kompletten Verarbeitungslinie nachhaltig und die Verteilung der Schneidkraft auf die Oberfläche der Druckerzeugnisse ist von den Fähigkeiten des Maschinenbedieners abhängig.Devices of the type mentioned are provided for trimming the three side edges of bound printed products and known to those skilled in the art as trimmers, trimmers, three-knife automatic machines or similar designations. The bound printed products are in a serial product stream, individually or in stacks fed to a cutting table while aligned to the back and / or the side edges, then pressed by means of a punch on the cutting table and cut in this position. For this purpose, the knives each execute a cutting movement directed against a cutting strip fastened to the cutting table. Three-knife trimmers working according to this principle ensure a good quality of the printed products with respect to the geometry and the cut surface. The disadvantage is that for the conversion to different formats usually both the ram, and the cutting table must be replaced according to the format. If the printed matter also contains inserts, such as pouches, samples, booklets or similar products, the thickness of the printed products may vary. In order to distribute the pressing force in the areas of the side edges, the topology of the press stamp must be adapted to the surface topology of the printed products according to the prior art. This adjustment work can be made only after the presence of the bound printed products, so that the remaining, already furnished plant parts can not produce until the trimmer is set up. The changeover time of the three-knife trimmer thus adversely affects the efficiency of a complete processing line and the distribution of the cutting force on the surface of the printed products depends on the capabilities of the machine operator.

In der DE-A-199 05 459 ist eine Vorrichtung zum Beschneiden von zu einem Stapel zusammengefassten Druckbögen offenbart. Die Druckbögen werden zu Wertpapieren verarbeitet, die zur Fälschungssicherung mit einem Wasserzeichen und/oder einem Prägedruck versehen sind. Ein Stapel von Druckbögen weist demzufolge im Bereich der Fälschungssicherung einen signifikanten hervorstehenden Bereich auf. Zur Erreichung einer hohen Formatgenauigkeit müssen die Stapel während dem Schneidevorgang mittels eines Pressstempels gegen einen, eine glatte Oberfläche aufweisenden, tragenden Tisch gepresst werden. Die Unterseite einer mit dem Pressstempel verbundenen Pressplatte weist eine Pressfläche auf, die genau in den Bereichen, in denen die mit einem Prägedruck versehenen Flächen in dem Stapel übereinander liegen, mit vielen Vertiefungen versehen ist. Die Vertiefungen sind exakt wie die hervorstehenden Bereiche der Druckbögen geformt und können mit einer elastischen Einlage versehen sein. Beim Pressen des Staples greifen nun die herausragenden Bereiche des Stapels in die Vertiefungen des Pressstempels ein, während die Pressfläche in den Bereichen ohne Prägedruck auf den Stapel Druck ausübt. Der Pressstempel muss demzufolge bei einer Änderung des Prägedrucks ebenfalls ausgetauscht oder angepasst werden. übereinander liegen, mit vielen Vertiefungen versehen ist. Die Vertiefungen sind exakt wie die hervorstehenden Bereiche der Druckbögen geformt und können mit einer elastischen Einlage versehen sein. Beim Pressen des Staples greifen nun die herausragenden Bereiche des Stapels in die Vertiefungen des Pressstempels ein, während die Pressfläche in den Bereichen ohne Prägedruck auf den Stapel Druck ausübt. Der Pressstempel muss demzufolge bei einer Änderung des Prägedrucks ebenfalls ausgetauscht oder angepasst werden.In the DE-A-199 05 459 a device for trimming printed sheets combined into a stack is disclosed. The signatures are processed into securities which are provided with a watermark and / or an embossing for counterfeiting. Consequently, a stack of signatures has a significant protruding area in the area of the anti-counterfeiting device. To achieve a high format accuracy, the stack must be pressed during the cutting process by means of a press ram against a, having a smooth surface bearing table. The underside of a pressing plate connected to the pressing die has a pressing surface which is exactly in the areas in which the embossed surfaces in the stack lie one above the other, provided with many depressions. The recesses are shaped exactly like the protruding areas of the signatures and can be provided with an elastic insert. When the staple is pressed, the protruding areas of the stack now engage in the depressions of the press ram, while the pressing surface exerts pressure on the stack in the areas without embossing pressure. The punch must therefore also be replaced or adjusted when changing the embossing. lie one above the other, provided with many depressions.

Es ist Aufgabe der Erfindung, eine Vorrichtung zu schaffen, mittels der die Presskraft effizient und die Druckerzeugnisse schonend auf die Druckerzeugnisse verteilbar ist. Es ist eine weitere Aufgabe der Erfindung, bei einer Produktionsumstellung von einem Druckerzeugnis auf das nächste, die Umrüstzeit kurz zu halten.It is an object of the invention to provide a device by means of which the pressing force can be distributed efficiently and the printed products gently on the printed products. It is a further object of the invention to keep the changeover time short during a production change from one printed product to the next.

Die an die Erfindung gerichtete Aufgabe wird erfindungsgemäss dadurch gelöst, dass der Schneidtisch einen dem Pressstempel gegenüberliegenden, aus der Schneidleiste gebildeten und in Pressgegenrichtung erhöhten Gegenpressrand aufweist, der einen Expansionsraum in dem Schneidtisch bildet, in den eine zweite elastische Einlage einsetzbar ist.The object of the invention is achieved according to the invention in that the cutting table has a pressing ram opposite, formed from the cutting bar and increased in press counter-direction counterpressure edge, which forms an expansion space in the cutting table, in which a second elastic insert can be used.

Eine in Fig.1 dargestellte Schneideinrichtung 1 ist für das Beschneiden wenigstens einer Seitenkante 2 gebundener resp. gehefteter Buchblocks, Bücher, Zeitschriften oder dgl. Druckerzeugnisse 3 vorgesehen. Die Druckerzeugnisse 3 werden dabei in einem Förderstrom einzeln oder in aus mehreren Druckerzeugnissen 3 gebildeten Stapeln in Förderrichtung F einem Schneidtisch 4 der Schneideinrichtung 1 flach aufliegend zugeführt. Die dem Schneidtisch 4 jeweils in eine Schneidposition zugeführten Druckerzeugnisse 3 werden zumindest während dem Schneidvorgang mittels eines gegen den Schneidtisch 4 pressenden, auf das Druckerzeugnis 3 absenk- und von diesem anhebbaren Pressstempel 5 gehalten und durch aus einer Ausgangsstellung gegen den Schneidtisch 4 resp. gegen Schneidleisten 7 oder Gegenmesser angetriebene Schneidmesser 6 beschnitten. Bei der Verarbeitung von Druckerzeugnissen 3, die über ihre flächigen Seiten 8 eine konstante Dicke aufweisen, können die Oberflächen des Pressstempels 5 und des Schneidtischs 4 als ebene Flächen ausgebildet sein. Sollen, wie in den Fig. 2 und Fig. 3 dargestellt, Druckerzeugnisse 3 mit eingefügten Beilagen 9, wie beispielsweise mit einer Flüssigkeit gefüllte Beutel oder Warenmuster, beschnitten werden, müssen in diesen Bereichen der Pressstempel 5 und/oder der Schneidtisch 4 derart gestaltet werden, dass keine übermässige Druckkraft auf die Beilagen 9 entsteht. Der Pressstempel 5 weist deshalb einen den Druckerzeugnissen 3 im Näherungsbereich der Seitenkante 2 zugewandten, in Pressrichtung P erhöhten Pressrand 10 auf. Ein durch den Pressrand 10 des Pressstempels 5 gebildeter, dem Schneidtisch 4 gegenüberliegender Expansionsraum 11, ist zur Aufnahme einer nachgiebigen Einlage 12 aus einem elastischen oder viscoelastischen Werkstoff gebildet. Vorzugsweise überragt die Einlage 12 den Pressrand 10 im unbelasteten Zustand leicht. Für den Zugriff zu den flächigen Seiten 8 der Druckerzeugnisse 3 einer durch ein Unterband und Oberband oder einen Greifer ausgebildeten Ausfördervorrichtung sind am Pressstempel 4 und am Schneidtisch 3 Aussparungen 13 vorgesehen. Bei der Verarbeitung von Druckerzeugnissen 3, die gemäss Fig. 4 aus Standarddruckbogen und kürzeren Druckbogen gebildet sind, wird vorzugsweise die Pressrandhöhe 14 an die unregelmässige Topologie eines Druckerzeugnisses 3 angepasst. Dies kann dadurch erreicht werden, dass der Pressstempel 5 gemäss den Fig. 4 und Fig. 7 mehrteilig aufgebaut wird, beispielsweise mit einer Grundplatte 15 und daran befestigten, den Pressrand 10 bildenden Pressleisten 16, deren Höhe an die Topologie der Druckerzeugnisse 3 angepasst ist. Der Pressstempel 5 ist mit einem in Pressrichtung P in einer Stempelführung 17 bewegbaren Stempelhalter 18 fest verbunden.An in Fig.1 shown cutting device 1 is for the trimming of at least one side edge 2 bound resp. stapled book block, books, magazines or the like. Printed 3 provided. The printed products 3 are fed in a single flow or in stacks formed from a plurality of printed products 3 in the conveying direction F to a cutting table 4 of the cutting device 1 lying flat. The the cutting table 4 each supplied to a cutting position printed products 3 are at least during the cutting process by means of a pressed against the cutting table 4, lowered onto the printed product 3 and held by this press ram 5 and held by a starting position against the cutting table 4, respectively. trimmed against cutting edges 7 or counter knife driven cutting blade 6. In the processing of printed products 3, which have a constant thickness over their flat sides 8, the surfaces of the press ram 5 and the cutting table 4 can be formed as flat surfaces be. Should, as in the Fig. 2 and Fig. 3 shown, printed products 3 with inserted inserts 9, such as with a liquid-filled bags or samples, are trimmed in these areas of the ram 5 and / or the cutting table 4 must be designed so that no excessive pressure force on the inserts 9 is formed. The press ram 5 therefore has a press edge 10 facing the printed products 3 in the vicinity of the side edge 2 and raised in the pressing direction P. A formed by the pressing edge 10 of the ram 5, the cutting table 4 opposite expansion space 11 is formed to receive a resilient insert 12 of an elastic or viscoelastic material. Preferably, the insert 12 projects slightly beyond the pressing edge 10 in the unloaded state. For access to the flat sides 8 of the printed products 3 of a discharge device formed by a lower belt and upper belt or a gripper, 3 recesses 13 are provided on the ram 4 and on the cutting table. In the processing of printed matter 3, according to Fig. 4 are formed of standard printing sheet and shorter sheet, preferably the pressing edge height 14 is adapted to the irregular topology of a printed product 3. This can be achieved in that the press ram 5 according to the Fig. 4 and Fig. 7 is constructed in several parts, for example, with a base plate 15 and attached thereto, the pressing edge 10 forming pressure bars 16 whose height is adapted to the topology of the printed products 3. The press ram 5 is firmly connected to a punch holder 18 which can be moved in the pressing direction P in a punch guide 17.

In einer weiteren Ausführungsvariante weist der mit einem Maschinengestell 19 fest verbundene Schneidtisch 4 einen dem Pressstempel 5 gegenüberliegenden, aus den Schneidleisten 7 und dem Schneidtisch 4 gebildeten und in Pressgegenrichtung G wirkenden Gegenpressrand 20 auf, der einen Expansionsraum 21 in dem Schneidtisch 4 bildet, in den eine zweite elastische Einlage 22 einsetzbar ist. Damit ist eine Verarbeitung von Druckerzeugnissen 3 mit grösseren Dickenunterschieden möglich und/oder eine grössere Schnittgenauigkeit der Seitenkanten 2 erreichbar. Obwohl die erfindungsgemässe Einrichtung für das Schneiden resp. Pressen von Druckerzeugnissen 3 mit einer unregelmässigen Dicke vorgesehen ist, ist diese auch bei der Verarbeitung von Druckerzeugnissen 3 mit regelmässiger Dicke einsetzbar.In a further embodiment variant, the cutting table 4 fixedly connected to a machine frame 19 has a counterpressure edge 20 which is opposite the press ram 5 and which is formed by the cutting edges 7 and the cutting table 4 and which acts in the press direction G, forming an expansion space 21 in the cutting table 4 a second elastic insert 22 can be used. For a processing of printed products 3 with larger thickness differences is possible and / or greater accuracy of the side edges 2 can be achieved. Although the inventive device for cutting resp. Pressing of printed matter 3 is provided with an irregular thickness, this can also be used in the processing of printed products 3 with regular thickness.
