Definitions
- the invention relates to a device for the adhesive binding of book blocks formed from compressed sheet that pass on a conveying path of a perfect binder to a book block spine about an approximately vertical axis of rotation notching tool having for the production of arcuate notches in the book block back dipping cutting teeth, the frontally protruding a carrier of the notching tool are attached.
- the CE 303 678 teaches a method and apparatus for the seamless incorporation of books, with which the sheets of paper gathered into book blocks on the back side in the wines notched, that arcuate, mutually crossing notches on the back, is applied to the glue.
- the apparatus consists of a conveyor for moving a book block along a conveying path, the back of the book block projecting for processing. Opposite the book block back a notching device is arranged, which has an inclined in the conveying direction of the book block disc which is driven about a vertical axis.
- This axis of rotation is hollow and concentric with a shaft is mounted within the axis of rotation, which extends at one end for driving a notching tool on the disc out.
- the notching tool consists of three mutually adjacent Fräsdorfn that leave when passing the book block back transverse to the conveying direction, different depths notches or grooves that are perpendicular to the inclined disc. That is, with each revolution of the disc, three notches are produced, each extending at different depths into the spine of the book block.
- the slanted grooves help to better anchor the glue on the back of a book block.
- the device used for this is associated with a relatively high cost.
- the present invention has an improvement in both the anchoring of the glue in the back of a book block and the stapling effect compared to the US 4'741'236 A task.
- the object is achieved in that the carrier of the notching tool has at least two opposite to the axis of rotation cutting teeth, which are aligned at an acute angle to a cutting circle plane.
- At least one of the cutting teeth has a position inclined toward the cutting center of the notching tool, so that during machining a mutually opposing inclined position of the notches is created.
- the same structure of the notches may arise when at least one of the cutting teeth has a radially outwardly inclined position from the cutting center.
- the carrier of the notching tool can be driven about an axis of rotation perpendicular to the conveying path, so that the book block back is possibly simultaneously trimmed by two spaced apart cutting teeth at the same time.
- the Book block spines are notched from a forward end, with opposite orientation of the cutting teeth on the carrier at the book block spine results in uniform alignment of the notches, whereas with uniform alignment of the cutting teeth on the book block spine, an opposing score structure results.
- the distance resp. the structure of the notches along the book block spine can be determined by the speed adjustment of the scoring tool and / or the speed of the book blocks on the conveyance path of the perfect binder.
- FIGS. 1 and 2 show a device for notching a printed sheet compressed at least on the lateral flanks of a book block spine 1 of a book block 2 (partially visible), the book block 2 being raised or facing the book block spine 1 of the scoring device in the direction F along a conveying path an adhesive binder is transported.
- the book block 2 clamped in a staple of the perfect binder passed a milling station in which the folded edges of the individual printed sheets were removed by cutting, so that for the subsequent notching process of the book block back 1 has a largely planar structure.
- the book block spine 1 for notching the book block spine 1 consists essentially of a, preferably disk-like carrier 3, which is connected to a drive shaft 4 and two the book block back 1 facing cutting teeth 5, which, as in the illustrated embodiment recognizable , are attached to the carrier 3 above the axis of rotation 6 vis-à-vis.

Description
Die Erfindung betrifft eine Vorrichtung zum Klebebinden von aus zusammengepressten Druckbogen gebildeten Buchblöcken, die auf einem Förderpfad eines Klebebinders ein zu einem Buchblockrücken um eine etwa senkrechte Drehachse rotierendes Kerbwerkzeug passieren, das zur Herstellung von bogenförmigen Kerben in den Buchblockrücken eintauchende Schneidzähne aufweist, die stirnseitig vorstehend an einem Träger des Kerbwerkzeuges befestigt sind.The invention relates to a device for the adhesive binding of book blocks formed from compressed sheet that pass on a conveying path of a perfect binder to a book block spine about an approximately vertical axis of rotation notching tool having for the production of arcuate notches in the book block back dipping cutting teeth, the frontally protruding a carrier of the notching tool are attached.
Die CE 303 678 vermittelt ein Verfahren und eine Vorrichtung zum fadenlosen Einbinden von Büchern, mit denen die zu Buchblocks zusamengelegten Blätter auf der Rückiseite in der Weine gekerbt werden, dass bogenförmige, sich gegenseitig kreuzende Kerben an dem Rücken entstehen, auf den Leim aufgetragen wird.The CE 303 678 teaches a method and apparatus for the seamless incorporation of books, with which the sheets of paper gathered into book blocks on the back side in the wines notched, that arcuate, mutually crossing notches on the back, is applied to the glue.
Für die Haltbarkeit eines klebegebundenen Buchblockrückens ist dessen mechanische Bearbeitung ebenso wichtig wie die Beleimung. Mit der Bearbeitung des Buchblockrückens wird eine Vergrösserung der zur Beleimung verfügbaren Blattoberfläche angestrebt.
Gestrichene oder für Kunstdruck geeignete Papiere erschweren die Klebebindung eines Buchblockrückens aufgrund der hierzu unzureichenden Eigenschaften.For the durability of a bound book block back its mechanical processing is as important as the gluing. With the processing of the book block back an enlargement of the sheet surface available for gluing is sought.
Coated or fine art papers complicate the perfect binding of a book block spine due to insufficient properties.
Nicht zuletzt aus diesem Grund wird eine verbesserte Bindung über eine Optimierung der Buchblockrücken-Struktur gesucht, mit der Massgabe, die Buchblockrückenoberfläche für den aufgetragenen Klebstoff zu vergrössern und damit die Steifigkeit mit einer günstigen Klammerwirkung zu verbessern.Not least for this reason, an improved binding is sought through an optimization of the book block spine structure, with the proviso to enlarge the book block back surface for the applied adhesive and thus to improve the rigidity with a favorable clamping effect.
Dieses Ziel verfolgt u.a. die US 4'741'236 A mit einer Vorrichtung zum Kerben eines Buchblockrückens. Die Vorrichtung besteht aus einem Förderer zum Bewegen eines Buchblocks entlang einem Förderpfad, wobei der Rücken des Buchblocks zum Bearbeiten vorsteht. Gegenüber dem Buchblockrücken ist eine Kerbvorrichtung angeordnet, die eine in Förderrichtung des Buchblocks geneigte Scheibe aufweist, welche um eine senkrechte Achse angetrieben ist. Diese Drehachse ist hohl ausgebildet und konzentrisch dazu ist innerhalb der Drehachse eine Welle gelagert, die sich einenends zum Antrieb eines Kerbwerkzeuges über die Scheibe hinaus erstreckt. Das Kerbwerkzeug besteht aus drei nebeneinander angeordneten Fräsblättern, die beim Passieren des Buchblockrückens quer zur Förderrichtung verlaufende, unterschiedlich tiefe Kerben oder Nuten hinterlassen, die senkrecht zur geneigten Scheibe stehen. D.h., mit jeder Umdrehung der Scheibe werden drei Kerben produziert, die sich jeweils unterschiedlich tief in den Rücken des Buchblocks erstrecken. Die schräggestellten Nuten verhelfen zu einer günstigeren Verankerung des Leims am Rücken eines Buchblocks. Die dazu verwendete Vorrichtung ist mit einem relativ hohen Aufwand verbunden.This goal is pursued i.a. US 4'741'236 A with a device for notching a book block spine. The apparatus consists of a conveyor for moving a book block along a conveying path, the back of the book block projecting for processing. Opposite the book block back a notching device is arranged, which has an inclined in the conveying direction of the book block disc which is driven about a vertical axis. This axis of rotation is hollow and concentric with a shaft is mounted within the axis of rotation, which extends at one end for driving a notching tool on the disc out. The notching tool consists of three mutually adjacent Fräsblättern that leave when passing the book block back transverse to the conveying direction, different depths notches or grooves that are perpendicular to the inclined disc. That is, with each revolution of the disc, three notches are produced, each extending at different depths into the spine of the book block. The slanted grooves help to better anchor the glue on the back of a book block. The device used for this is associated with a relatively high cost.
Die vorliegende Erfindung hat sich eine Verbesserung sowohl der Verankerung des Leims im Rücken eines Buchblocks als auch der Klammerwirkung gegenüber der US 4'741'236 A zur Aufgabe gemacht.The present invention has an improvement in both the anchoring of the glue in the back of a book block and the stapling effect compared to the US 4'741'236 A task.
Erfindungsgemäss wird die Aufgabe dadurch gelöst, dass der Träger des Kerbwerkzeuges wenigstens zwei sich an der Drehachse gegenüberliegende Schneidzähne aufweist, die in einem spitzen Winkel zu einer Schneidkreisebene ausgerichtet sind. Dadurch lässt sich in dem Buchblockrücken eine Struktur von Kerben verwirklichen, mit der die Steifigkeit und Klammerwirkung eines Buchblockrückens spürbar verbessert wird.According to the invention, the object is achieved in that the carrier of the notching tool has at least two opposite to the axis of rotation cutting teeth, which are aligned at an acute angle to a cutting circle plane. As a result, a structure of notches can be realized in the book block back, with the stiffness and stapling effect of a book block back is noticeably improved.
Vorteilhaft weist wenigstens einer der Schneidzähne eine zum Schneidkreiszentrum des Kerbwerkzeuges hin geneigte Lage auf, so dass bei der Bearbeitung eine wechselweise entgegengerichtete Neigungslage der Kerben entsteht.Advantageously, at least one of the cutting teeth has a position inclined toward the cutting center of the notching tool, so that during machining a mutually opposing inclined position of the notches is created.
Die gleiche Struktur der Kerben kann entstehen, wenn wenigstens einer der Schneidzähne eine von dem Schneidkreiszentrum radial nach aussen geneigte Lage aufweist.The same structure of the notches may arise when at least one of the cutting teeth has a radially outwardly inclined position from the cutting center.
Der Träger des Kerbwerkzeuges kann um eine zum Förderpfad senkrecht angeordnete Drehachse angetrieben sein, sodass der Buchblockrücken jeweils von zwei im Abstand sich gegenüberliegenden Schneidzähnen möglicherweise gleichzeitig beschnitten wird.The carrier of the notching tool can be driven about an axis of rotation perpendicular to the conveying path, so that the book block back is possibly simultaneously trimmed by two spaced apart cutting teeth at the same time.
Mit jeder Umdrehung des Kerbwerkzeuges resp. Trägers werden zwei Kerben von einem Schneidzahn geschnitten.With each revolution of the notching tool resp. Carrier two notches are cut by a cutting tooth.
Oder bei einem Träger des Kerbwerkzeuges, der um eine zum Förderpfad geneigt angeordnete Achse angetrieben ist, kann der Buchblockrücken von einem in Förderrichtung vorderen Ende aus gekerbt werden, wobei bei entgegengesetzter Ausrichtung der Schneidzähne an dem Träger am Buchblockrücken eine gleichförmige Ausrichtung der Kerben entsteht, wogegen bei gleichförmiger Ausrichtung der Schneidzähne am Buchblockrücken eine entgegengerichtete Kerbstruktur entsteht.Or in a carrier of the notching tool, which is driven about an axis arranged inclined to the conveying path, the Book block spines are notched from a forward end, with opposite orientation of the cutting teeth on the carrier at the book block spine results in uniform alignment of the notches, whereas with uniform alignment of the cutting teeth on the book block spine, an opposing score structure results.
Der Abstand resp. die Struktur der Kerben entlang des Buchblockrückens kann über die Drehzahlverstellung des Kerbwerkzeuges und/oder über die Geschwindigkeit der Buchblöcke auf dem Förderpfad des Klebebinders bestimmt werden.The distance resp. the structure of the notches along the book block spine can be determined by the speed adjustment of the scoring tool and / or the speed of the book blocks on the conveyance path of the perfect binder.

Die Fig. 1 und 2 zeigen eine Vorrichtung zum Kerben eines zumindest an den seitlichen Flanken eines Buchblockrückens 1 eines Buchblocks 2 (teilweise ersichtlich) zusammengepressten Druckbogen, wobei der Buchblock 2 hochgestellt bzw. mit dem Buchblockrücken 1 der Kerbvorrichtung zugewandt in Richtung F entlang einem Förderpfad eines Klebebinders transportiert wird. Zuvor passierte der Buchblock 2 eingespannt in einer Klammer des Klebebinders eine Frässtation, in der die Falzkanten der einzelnen Druckbogen spanend entfernt worden sind, sodass für den anschliessenden Kerbvorgang der Buchblockrücken 1 eine weitgehend ebene Struktur aufweist.
Die in den Fig. 1 und 2 dargestellte Vorrichtung zum Kerben des Buchblockrückens 1 besteht im Wesentlichen aus einem, vorzugsweise scheibenartigen Träger 3, der mit einer Antriebswelle 4 verbunden ist und zwei dem Buchblockrücken 1 zugewandte Schneidzähne 5 aufweist, die, wie im dargestellten Ausführungsbeispiel erkennbar, vis-à-vis von der Drehachse 6 am Träger 3 vorstehend befestigt sind. Die in gleicher Neigungsrichtung an dem Träger 3 vorstehenden Schneidzähne 5 ergeben eine Kerbstruktur, wie sie in Fig. 3 veranschaulicht ist, d.h. jeweils ein Kerbenpaar weist entgegengesetzt ausgerichtete Kerben auf bzw. die in Längsrichtung eines Buchblockrückens aneinandergereihten Kerben weisen wechselweise entgegengerichtete Vertiefungen auf. Die Vertiefungen könnten wechselweise unterschiedlich lang ausgebildet sein und es wäre denkbar, mehr als zwei Schneidzähne 5 an dem Träger 3 zu befestigen. Der Abstand der Kerben richtet sich nach der Fördergeschwindigkeit der Buchblöcke und der Umlaufgeschwindigkeit der Schneidzähne 5, deren Umlaufrichtung durch Pfeil R in Fig. 2 vermerkt ist. Der zur Meidung ungleichmässiger Rotationskräfte kreisrund ausgebildete Träger 3 ist gegenüber dem passierenden Buchblockrücken 1 des Buchblocks 2 in eine leichte Schräglage versetzt, sodass jeweils nur ein Schneidzahn 5 an der gleichen Stelle über die Buchblockrückenbreite in den Buchblockrücken 1 eintaucht, wobei die Eintauchstrecke wenigstens die Länge der Buchblockdicke aufweist und eine kreisbogenförmige Kerbe hinterlässt. Die Schneidzähne 5 sind in einem gegenüber der von ihnen gebildeten Schneidebene spitzen Winkel β durch einen Schaft 9 in Ausnehmungen 7, 8 des Trägers 3 befestigt, vorzugsweise austauschbar befestigt. Die Ausnehmungen 7, 8 sind im Querschnitt dreieckförmig und weisen im Sinne einer seitlichen Halterung etwa die Breite eines Schaftes 9 eines Schneidzahnes 5 auf. Die Schneidzähne 5 können an ihrem Schaft 9 an dem Träger 3 festgelötet oder festgeschraubt sein.1 and 2 show a device for notching a printed sheet compressed at least on the lateral flanks of a

Fig. 3 vermittelt ein Bild der durch die in den Fig. 1 und 2 dargestellte Vorrichtung hergestellte Kerbstruktur an einem Buchblockrücken, wobei die Kerbabschnitte deutlich machen, dass sich der Rand des Buchblockrückens 1 beim Kerben etwa in der Drehachse 6 des Kerbwerkzeuges befindet.Fig. 3 provides an image of the notch structure formed by the apparatus shown in Figs. 1 and 2 on a book block spine, the notch portions making it clear that the edge of the
Die Fig. 4 bis 6b vermitteln eine alternative Ausführung des Kerbwerkzeuges und der Kerbstruktur.
Gemäss Fig. 4 sind die Schneidzähne 5 am Umfang eines scheibenförmigen Trägers 3 befestigt, der die Querschnittsform eines Kegelstumpfs aufweist. Die Schneidzähne 5 sind entlang einer Mantellinie des Trägers 3 befestigt bzw. auswechselbar befestigt und es handelt sich um die gleichen Schneidzähne 5, die schon in den Fig. 1 und 2 gezeichnet sind. Selbstverständlich könnten die Schneidzähne 5 auch in Ausnehmungen befestigt sein.
Ein weiterer Unterschied gegenüber den Fig. 1 und 2 besteht darin, dass die Drehachse 6 bzw. die mit dem Träger 3 verbundene Antriebswelle 4 etwa senkrecht zum Förderpfad bzw. zum Buchblockrücken 1 ausgerichtet ist, sodass jeweils beide der sich an der Drehachse 6 gegenüberliegenden Schneidzähne 5 Kerben in den Buchblockrücken 1 schneiden, wobei beide Schneidzähne 5 gleichermassen an der Herstellung der sich widerspiegelnden Kerbabschnittspaare 10 beteiligt sind (siehe auch Fig. 6a und 6b), deren Anordnung der Fig. 4 entnehmbar ist. Wie schon in Fig. 3 ist auch gemäss den Fig. 6a und 6b die Kerbstruktur nicht symmetrisch zur Längsachse des Buchblockrückens 1 angelegt.FIGS. 4 to 6 b provide an alternative embodiment of the notching tool and the notch structure.
According to FIG. 4, the cutting
