Description

Die Erfindung betrifft ein Verfahren nach dem Oberbegriff des Patentanspruches 1.The invention relates to a method according to the preamble of claim 1.

Nach der Fertigung in den Klebebindeanlagen werden die in Umschläge gebundenen Buchblöcke über Fördereinrichtungen einer Schneideinrichtung zugeführt, beispielsweise einem Dreiseitenschneider.After production in the perfect binding machines, the book blocks bound in envelopes are conveyed to a cutting device via conveyor devices, for example a three-sided cutter.

Dabei gelangen die gebundenen Buchblöcke einzeln oder mehrfach aufeinanderliegend mit dem Rücken voraus in die Schneideinrichtung und werden hiermit dem Rücken an einen Anschlag gepresst; diese Möglichkeit schliesst nicht aus, dass das, Schneidgut schon früher ausgerichtet und mit der offenen Seite voraus in die Schneideinrichtung geführt wird. Ebenso schreibt das Verfahren nicht vor, dass der Frontschnitt zeitlich vor den Kopf- und Fussschnitten durchgeführt wird, was umgekehrt auch praktikabel ist.The bound book blocks, one or more lying one on top of the other, reach the cutting device with their backs ahead and are hereby pressed against a stop with their backs; this possibility does not rule out that the material to be cut is aligned earlier and is guided into the cutting device with the open side ahead. Likewise, the method does not stipulate that the front cut should be made before the head and foot cuts, which is also practical in reverse.

Neben den scherenschnittartigen Schneidmethoden oder einem Gegenmesser ist ein Beschnitt mit fräserartigen Werkzeugen ebensowenig wie die Schnittrichtung hinsichtlich Buchblockrücken von dem vorgeschlagenen Verfahren ausgeschlossen. Diesbezüglich wird auf bekannte einschlägige Lehrmittel, bspw. Technologie der Klebebindung, und andere Fachliteratur verwiesen.In addition to the scissor-cut-like cutting methods or a counter knife, trimming with cutter-like tools is just as impossible as the cutting direction with regard to the spine of the book block from the proposed method. In this regard, reference is made to known relevant teaching aids, for example technology of perfect binding, and other specialist literature.

In der Fertigung von Büchern, Broschüren oder Katalogen treten nach dem abschliessenden Beschneiden an den Kopf- und Fusseiten der Buchblöcke an den Kanten im Bereich des Rückens, insbesondere an der Übergangsstelle des Umschlagrückens zu den Umschlagklappen Beschädigungen durch aufbrechende Schichten bzw. fragmentartige Stellen auf.In the manufacture of books, brochures or catalogs, after the final trimming on the top and bottom sides of the book blocks, the edges in the area of the spine, in particular at the transition point of the spine of the cover to the cover flaps, cause damage due to breaking layers or fragment-like areas.

Solche Markierungen hinterlassen u.a. den Eindruck eines bereits benutzten Buches bzw. nicht mehr neuen Buches.Such markings leave the impression of a book that has already been used or is no longer new.

Eine Nachbearbeitung mit der selben Methode könnte die Behebung dieses Mangels wohl nur zufällig bewirken, das Problem jedoch keinesfalls lösen.Post-processing with the same method could only remedy this defect by accident, but in no way solve the problem.

Bei einer Papierschneidemaschine nach der EP - A - 0234 216 soll zur Meidung des beschriebenen Mangels eine an den Seitenmessern befestigte, auf den Rücken der Buchblöcke einwirkende Rückenanpressvorrichtung verwendet werden, die an dem freien Ende eine dem/den Buchrücken im Randbereich zugewendete Druckplatte aufweist. An ihrer Aussenkante besitzt die Druckplatte in unmittelbarer Nähe der Schneidkante einen spitzen Vorsprung, der, wenn sich die Druckplatte an den Buchrücken abstützt, einen partiell höheren Druck auf die Buchrücken erzeugt als dies durch die verbleibende Fläche der Druckplatte der Fall ist.In a paper cutting machine according to EP-A-0234 216, a back pressure device, which is attached to the side knives and acts on the spine of the book blocks and has a pressure plate on the free end facing the spine (s) in the edge area, is to be used to avoid the described defect. On its outer edge, the printing plate has a pointed projection in the immediate vicinity of the cutting edge, which, when the printing plate is supported on the book spine, generates a partially higher pressure on the book spines than is the case due to the remaining area of the printing plate.

Der in die Buchrücken eindringende Vorsprung soll angeblich verhindern, dass während des Schneidvorganges an Kopf- und Fusseite des Buches ein Ausreissen der Buchrücken praktisch vollständig verhindert wird.The protrusion penetrating the book spines is said to prevent the book spines from being practically completely prevented from being torn out at the top and bottom of the book during the cutting process.

Dadurch, dass der keilartig ausgebildete Vorsprung auf den am Buch verbleibenden Teil des Buchrückens einwirkt, weil das Seitenmesser auf der abgewandten Seite dem Vorsprung entlanggleiten soll, können Spannungen im Umschlag, insbesondere am Rücken und dessen Übergang zu den Umschlagklappen nicht vermieden werden, sodass der nachfolgende Kopf- und Fussschnitt schadhafte Stellen wie gehabt zurück lässt. Insbesondere die Übergangsstellen von Buchrücken an die Umschlagklappen sind auf diese bekannte Bearbeitungsweise von Beschädigungen kaum fernzuhalten.Due to the fact that the wedge-shaped projection acts on the part of the spine remaining on the book, because the side knife is supposed to slide along the projection on the opposite side, tensions in the cover, in particular on the back and its transition to the cover flaps, cannot be avoided, so that the following Head and foot cuts leave damaged areas as before. In particular, the transition points from book spines to the cover flaps can hardly be kept away from damage in this known processing method.

Aufgabe der vorliegenden Erfindung ist es somit, ein Verfahren und eine Vorrichtung zu schaffen, welches bzw. welche auf einfache Weise ein beschädigungsfreies Beschneiden der Kopf- und Fusseite sowie des Buchrückens gewährleisten.The object of the present invention is therefore to provide a method and a device which, in a simple manner, ensure damage-free trimming of the top and bottom of the page and the spine of the book.

Erfindungsgemäss wird diese Aufgabe gemäss dem kennzeichnenden Teil des Patentanspruches 1 gelöst.According to the invention, this object is achieved in accordance with the characterizing part of patent claim 1.

Durch dieses Vorgehen können keine sich an den Seitenrändern auf die Buchkanten auswirkenden Spannungen entstehen, schon deshalb nicht, weil durch den Schnitt im Buchrücken auftretende Spannungen nach aussen unterbrochen sind bzw. letztere schon bei wenigstens teilweise angeschnittenem Umschlagrücken, beispielsweise nach der Art einer Perforation, nicht nach aussen vollständig übertragbar sind.This procedure does not result in any stresses affecting the edges of the book on the side edges, if only because the cut that occurs in the spine is interrupted to the outside or the latter is not possible with the cover spine at least partially cut, for example in the manner of a perforation are fully transferable to the outside.

Tolerierbar ist bei einer geringfügigen Abweichung der Kopf- und Fussschnitte von dem Rückenanschnitt bzw. Rückenschnitt, wenn letzterer gegenüber ersteren nach innen versetzt ist, sodass durch die Zurücksetzung des Rückenbeschnittes gegenüber dem Kopf- und Fussschnitt der geringe Absatz vor einem Ausbrechen der Papierschichten geschützt ist.It is tolerable with a slight deviation of the head and foot cuts from the back cut or back cut, if the latter is offset inwards relative to the former, so that by setting the back cut back against the head and foot cut, the low heel is protected from breaking out of the paper layers.

Vorteilhafterweise wird der Umschlag am Rücken des Buchblockes vollständig durchgeschnitten, sodass beim Beschneiden von Kopf und Fuss keine Spannungen auf die Umschlagkanten im Bereich des Rückens übertragen werden.Advantageously, the cover on the back of the book block is completely cut through, so that when the head and foot are cut, no tension is transferred to the cover edges in the area of the back.

Als Vorrichtung zur Durchführung des erfindungsgemässen Verfahrens, mit jeweils einem für den Kopf- und Fussbeschnitt eines Buchlockes bestimmten Schneidmesser, ist fluchtend mit den Schneidmessern ein sich wenigstens über die Breite der Buchblockrücken erstreckendes und in den Umschlag letzterer schneidend eintauchbar angetriebenes Messer angeordnet, welches den Umschlag am Rücken der Buchblöcke wahlweise wenigstens teilweise anschneidet, perforiert oder durchschneidet.As a device for carrying out the method according to the invention, each with a cutting knife intended for the top and bottom trimming of a book lock, a knife is arranged in alignment with the cutting knives, which extends at least over the width of the book block spines and is immersed in the cover of the latter, which knife drives the cover at least partially cut, perforate or cut through the back of the book blocks.

Dieses Messer kann etwa senkrecht zu seiner Schnittkante bzw. Schneide gegen den Buchblockrücken und von diesem weg angetrieben sein, wobei sich dazu geradlinige Schneiden wie auch kreisrunde eignen, von denen letztere rotierend antreibbar ausgebildet sein können.This knife can be driven approximately perpendicular to its cutting edge or cutting edge against the book block spine and away from it, whereby straight-line cutting edges as well as circular ones are suitable, the latter of which can be designed to be driven in rotation.

Die Schneidbewegung und/oder Zustellbewegung des Messers kann zweckmässig durch mechanische und/oder hydraulische bzw. pneumatische Antriebsmittel erfolgen.The cutting movement and / or delivery movement The knife can expediently be provided by mechanical and / or hydraulic or pneumatic drive means.

Hierzu ist vorzugsweise eine mit dem Messer verbundene Kolben-Zylinder-Einheit vorgesehen.For this purpose, a piston-cylinder unit connected to the knife is preferably provided.

Das Messer weist vorteilhaft eine Nachschleifkante auf, die auf der der Schneidebene abgewendeten Seite angeordnet ist, dies gilt auch für kreisrunde, scheibenartige Messer.The knife advantageously has a regrinding edge which is arranged on the side facing away from the cutting plane; this also applies to circular, disk-like knives.

Das Messer kann an das zu schneidende Buchformat durch seitliches Versetzen angepasst werden.The knife can be adjusted to the book format to be cut by moving it to the side.

Zweckmässigerweise ist die Vorrichtung mit einem Anschlag für die Buchblockrücken ausgebildet, mit dem der Abstand der Buchblockrücken zum Messerhub einstellbar ist.The device is expediently designed with a stop for the book block spine with which the distance of the book block spine to the knife stroke can be adjusted.

Die Vorrichtung selbst ist an einem verstellbaren Anschlag befestigt, der beim Einsatz der Schneidmesser aus dem Schneidbereich entfernt wird.The device itself is attached to an adjustable stop which is removed from the cutting area when the cutting knives are used.

Nachstehend wird die Erfindung anhand einer in der Zeichnung beispielhaft dargestellten Ausführung erläutert. Die einzige Figur zeigt einen Grundriss des Schneidtisches einer Schneideinrichtung.The invention is explained below with reference to an embodiment shown as an example in the drawing. The single figure shows a floor plan of the cutting table of a cutting device.

Mit 1 ist ein verstellbarer Seitenanschlag eines nicht vollständig veranschaulichten Dreiseitenschneiders bezeichnet, der hinsichtlich Lage wenigstens eines mit strichpunktierter Linie angedeuteten, liegenden Buchblockes 3 aus diesem Bereich nach der Seite hin versetzbar ausgebildet ist.1 designates an adjustable side stop of a three-side cutter, which is not fully illustrated, and which is designed to be displaceable to the side from this area with regard to the position of at least one lying book block 3 indicated by a dash-dotted line.

An diesem Seitenanschlag 1 ist eine Vorrichtung 2 befestigt, mit welcher der Umschlag an den Rücken der Buchblöcke 3 in senkrechter Richtung zu den Lagen der gebundenen Druckprodukte beschnitten wird. Die Befestigung der Vorrichtung 2 ist durch die Senkkopfschraube 4 angedeutet.A device 2 is fastened to this side stop 1, with which the cover on the back of the book blocks 3 is trimmed in a direction perpendicular to the layers of the bound printed products. The attachment of the device 2 is indicated by the countersunk screw 4.

Die Vorrichtung 2 besteht aus einer doppelwirkenden Kolben-Zylinder-Einheit 5, deren Anschlüsse 6, 7 wechselweise mit einer nicht gezeichneten Druckquelleverbunden sind. In der gezeigten Lage befindet sich ein Messer 8 in der hinteren Endlage bzw. ausserhalb des Schneidbereiches, in welcher Lage ein mit dem Kolben 9 der Kolben-Zylinder-Einheit 5 verbundener Betätigungskolben 10 mit einer Schulter 11 stirnseitig an einer Kolbenführung 12 anliegt. Diese Kolbenführung 12 ist fluchtend mit der Längsachse des Kolbens 9 der Kolben-Zylinder-Einheit 5 an letzterer befestigt. In der Kolbenführung 12 ist eine Führungsbüchse 13 befestigt, die die Gleiteigenschaft des Betätigunskolbens 10 begünstigt.The device 2 consists of a double-acting piston-cylinder unit 5, the connections 6, 7 of which are alternately connected to a pressure source, not shown. In the position shown, there is a knife 8 in the rear end position or outside the cutting area, in which position an actuating piston 10 connected to the piston 9 of the piston-cylinder unit 5 rests with a shoulder 11 on the end face of a piston guide 12. This piston guide 12 is fastened in alignment with the longitudinal axis of the piston 9 of the piston-cylinder unit 5 on the latter. A guide bushing 13 is fastened in the piston guide 12 and promotes the sliding property of the actuating piston 10.

Damit das Messer 8 seitlich nicht abkippt, ist der Betätigungskolben 10 seitlich mit einer am Befestigungsteil 23 wenigstens annähernd anliegenden Führungsfläche 24 ausgestattet.So that the knife 8 does not tip sideways, the actuating piston 10 is laterally equipped with a guide surface 24 which is at least approximately in contact with the fastening part 23.

An dem der Schulter 11 gegenüberliegenden Ende des Betätigungskolbens 10 ist das Messer 8 in einer dafür bestimmten Ausnehmung 14 eines am Betätigungskolben 10 in Bewegungsrichtung vorstehenden Supports 15 eingespannt. Eine senkrecht zum Messer 8 verlaufende Gewindebohrung nimmt einen Gewindestift 16 zur lösbaren Arretierung des Messers 8 auf.At the end of the actuating piston 10 opposite the shoulder 11, the knife 8 is clamped in a recess 14 intended for this purpose in a support 15 projecting on the actuating piston 10 in the direction of movement. A threaded hole running perpendicular to the knife 8 receives a threaded pin 16 for releasably locking the knife 8.

Der Support ist wie mit strichpunktierter Linie bezeichnet, bspw. in einer Führung seitlich verstellbar angeordnet, sodass Buchblöcke unterschiedlichen Formats bzw. mit verschiedenen Endabschnitten bearbeitbar sind. Das Messer 8 ist mit einer Nachschleifkante 17 versehen, welche auf der Seite des vom Buchblock abgetrennten Umschlagteil vorgesehen ist, sodass am Buchrücken keinerlei schädliche Markierungen nach dem Gebrauch des Messers zurückbleiben.The support is designated as a dash-dotted line, for example laterally adjustable in a guide, so that book blocks of different formats or with different end sections can be processed. The knife 8 is provided with a regrinding edge 17 which is provided on the side of the cover part separated from the book block, so that no harmful markings remain on the book spine after use of the knife.

Ein winkelförmiger Anschlag 18 bestimmt den Abstand der Buchblockrücken zu dem ausstossbaren Messer 8 bzw. durch ihn kann die Schnittiefe im Umschlag am Rücken der Buchblöcke 3 bestimmt werden.An angular stop 18 determines the distance between the spine of the book block and the knife 8 that can be ejected, or it can be used to determine the depth of cut in the cover on the spine of the book block 3.

Die angedeutete Durchtrittsöffnung 19 im Anschlag 18 ist fluchtend zu dem Gewindestift 16 angeordnet und zur Betätigung letzterens mittels Inbusschlüssel oder Schraubenzieher vorgesehen.The indicated passage opening 19 in the stop 18 is aligned with the threaded pin 16 and provided for actuation of the latter by means of an Allen key or screwdriver.

Dervollständigkeithalber sei noch erwähnt, dass das Messer 8 in der Ausnehmung 14 mit einer geführten Platte 20 verbunden ist, wobei die Platte 20 eine Bohrung aufweist, in die der Gewindestift 16 eintaucht. Die strichpunktierte Linie 21 weist auf die eine Schnittebene eines nicht gezeichneten Schneidmessers hin.For the sake of completeness, it should also be mentioned that the knife 8 is connected in the recess 14 to a guided plate 20, the plate 20 having a bore into which the threaded pin 16 is immersed. The dash-dotted line 21 indicates the one cutting plane of a cutting knife, not shown.
