Abstract

A roughening tool (4) rotates around a rotary axis, which has machining surfaces penetrating the book block spine. The machining edges (9) rotate in a cutting plane and are arranged on the face side of the periphery of the roughening tool (4). The machining edges and the machining plane on the book block spine form a flat adjustment angle ( alpha ). The markings opposite each other, produced by the roughening tool extending laterally over the book block spine, have different machining depths. The un-roughened spine section and the rotary axis of the roughening tool form an angle of more than 90 degrees.

Description

Die Erfindung betrifft eine Vorrichtung zum Aufrauhen eines aus zusammengepressten Druckbogen gebildeten Buchblockrückens gemäss dem Oberbegriff nach Patentanspruch 1.The invention relates to a device for roughening a book block spine formed from compressed printed sheets according to the preamble of patent claim 1.

Bei der Verarbeitung von Buchblöcken zum Klebebinden aus wenigstens einfach gefalteten Druckbogen werden letztere nach dem Zusammentragen in eine Klemmvorrichtung eines Klebebinders überführt, in der sie anschliessend Bearbeitungsstationen passieren.
Dabei werden die in Falznähe zu einem Buchlockrücken zusammengepressten Druckbogen durch spanendes Abtrennen von den Falzen befreit. Dies geschieht beispielsweise bei Klebebindern von Müller Martini durch ein um eine senkrechte Achse rotierendes Kreismesser, welches eine relativ glatte Rückenfläche hinterlässt, die anschliessend, je nach Qualität des zu verarbeitenden Papieres, entsprechend aufgerauht werden muss, um eine günstige Verbindung der Oberfläche des Buchblockrückens mit dem verwendeten Klebstoff herstellen zu können.
Es werden aber auch Fräswerkzeuge zum Entfernen der Falze eingesetzt.In the processing of book blocks for perfect binding from at least single folded printed sheets, the latter are transferred after being gathered into a clamping device of a perfect binder, in which they then pass through processing stations.
The printed sheets pressed together in the vicinity of the fold to form a booklock spine are freed from the folds by cutting. For example, in the case of perfect binders from Muller Martini, this is done by a circular knife rotating around a vertical axis, which leaves a relatively smooth back surface, which then has to be roughened, depending on the quality of the paper to be processed, in order to ensure a favorable connection between the surface of the book block spine and the to be able to manufacture the adhesive used.
Milling tools are also used to remove the folds.

Beim anschliessenden Aufrauhen der Blattkanten resp. des beschnittenen Buchblockrückens werden aus Karbiden gebildete Schleifmittel verwendet.
Der Einsatz von Karborundumbelägen erfolgt gemäss "Technologie der Klebebindung", Alfred Furler, u.a. mit einem um eine senkrechte Achse rotierenden Teller, über den die Buchblöcke hinweggeführt werden.When roughening the sheet edges respectively. of the trimmed book block spine, abrasives formed from carbides are used.
Carborundum coverings are used according to "Perfect Binding Technology", Alfred Furler, including a plate rotating around a vertical axis over which the book blocks are guided.

Durch den anfallenden Schleifstaub verstopfen die Freiräume der Karborundumbeläge zwischen dem Schleifkorn und es entsteht eine Neigung zum Verschluss des Aufrauhwerkzeuges, der sich auch auf die Blattkanten überträgt.The resulting sanding dust clogs the free spaces of the carborundum coverings between the abrasive grain and there is a tendency to close the roughening tool, which is also transferred to the sheet edges.

Aufgabe der Erfindung ist es somit, eine Vorrichtung zum Aufrauhen von rückenseitig beschnittenen Buchblöcken zu schaffen, mit welcher Papierfasern an den Blattkanten freigelegt resp. Füllstoffe herausgehoben werden können, um die mit dem Klebstoff zu verbindende Oberfläche des Buchblockrückens zu optimieren.The object of the invention is therefore to provide a device for roughening back-trimmed book blocks, with which paper fibers are exposed on the sheet edges or. Fillers can be lifted out in order to optimize the surface of the book block spine to be connected with the adhesive.

Erfindungsgemäss wird diese Aufgabe nach dem Kennzeichen des Patentanspruches 1 gelöst.
Dadurch kann ein wirkungsvollerer Aufrauheffekt an dem Buchblockrücken als beispielsweise durch das Verfahren und die Vorrichtung nach der WO 91/06435 erzielt werden.
Daraus ergibt sich, dass der unaufgerauhte Rückenabschnitt des Buchblockes und die Drehachse des Aufrauhwerkzeuges einen Winkel von mehr als 90° bilden.According to the invention, this object is achieved according to the characterizing part of patent claim 1.
As a result, a more effective roughening effect on the book block spine can be achieved than, for example, by the method and the device according to WO 91/06435.
This means that the un-roughened back section of the book block and the axis of rotation of the roughening tool form an angle of more than 90 °.

Da eine weitgehend gleichmässig ebene Rückenfläche gewünscht ist, ist der Anstellwinkel α mit Rücksicht auf den Durchmesser des Aufrauhwerkzeuges entsprechend einzuhalten.
Durch die nachwirkende, tiefere Aufrauhbewegung werden die von den vorlaufenden Bearbeitungskanten seitlich verlegten Blattkanten wieder in die ursprüngliche Lage zurückversetzt und dabei leicht aufgefächert, wodurch die Klebeverbindung weiter begünstigt wird.Since a largely even back surface is desired, the angle of attack α must be observed accordingly, taking into account the diameter of the roughening tool.
Due to the deeper roughening action, the sheet edges laid laterally by the leading processing edges are returned to their original position and slightly fanned out, which further promotes the adhesive bond.

Vorteilhaft sind die Bearbeitungskanten des Aufrauhwerkzeuges am Umfang eines kreisförmigen Halters angeordnet, wodurch eine regelmässige Verteilung der Markierungen am Buchblockrücken entstehen kann.The processing edges of the roughening tool are advantageously arranged on the circumference of a circular holder, as a result of which a regular distribution of the markings on the spine of the book block can arise.

Als geeignete Bearbeitungskanten erweisen sich Schneidelemente, die durch einen erzielbaren Schneideffekt eine schonende Behandlung der Blattkanten beim Freilegen von Papierfasern und/oder Ausheben von Füllstoffen gestatten.Suitable processing edges have been found to be cutting elements which, through an achievable cutting effect, permit gentle treatment of the sheet edges when paper fibers are exposed and / or fillers are excavated.

Eine Optimierung der Oberfläche des Buchblockrückens kann dadurch erreicht werden, wenn die Umfangsgeschwindigkeit der Bearbeitungskanten in Abstimmung mit der Fortbewegungsgeschwindigkeit eines Buchblockes so gewählt wird, dass sich die kreisförmigen Markierungen überschneiden.An optimization of the surface of the book block spine can be achieved if the peripheral speed of the processing edges is selected in coordination with the speed of travel of a book block so that the circular markings overlap.

Anschliessend wird die Erfindung unter Bezugnahme auf die Zeichnung, auf die bezüglich aller in der Beschreibung nicht näher erwähnten Einzelheiten ausdrücklich verwiesen wird, anhand eines Ausführungsbeispiels erläutert. In der Zeichnung zeigen:

a view from below according to FIG. 1.

In den Fig. 1 und 2 ist eine Vorrichtung 1 zum Aufrauhen des Buchblockrückens eines in einer Klemmzange 2 eines nicht ersichtlichen Klebebinders eingespannten Buchblockes 3 veranschaulicht. Die Pfeilrichtung F in Fig. 1 weist auf die Transportrichtung des ein Aufrauhwerkzeug 4 einer Bearbeitungsstation des Klebebinders passierenden Buchblockes 3 hin.
Dem in der Klemmzange 2 aus zusammengepressten einzelnen Druckbogen gebildeten Buchblock wurden zuvor in einer vorgeschalteten Bearbeitungsstation am Aushang 5 die Falze der Druckbogen durch Beschneiden oder Fräsen entfernt.
In der Aufrauhstation werden die durchziehenden Buchblockrükken zur Optimierung der Klebeverbindung mit einer rauhen Oberfläche ausgebildet, um an den Blattkanten der Druckbogen Papierfasern freizulegen resp. Füllstoffe aus der Blattkante herauszuheben.1 and 2 illustrate a device 1 for roughening the back of the book block of a book block 3 clamped in a clamp 2 of a non-visible perfect binder. The direction of arrow F in FIG. 1 indicates the transport direction of the book block 3 passing a roughening tool 4 of a processing station of the perfect binder.
The folds of the printed sheets were previously removed by trimming or milling in the upstream processing station on the display 5 of the book block formed in the clamping pliers 2 from compressed individual printed sheets.
In the roughening, the pulling book block spines are formed to optimize the adhesive connection with a rough surface in order to expose paper fibers on the sheet edges of the printed sheets. Lift fillers out of the sheet edge.

Das mit der Antriebswelle 6 eines Motors 7 verbundene Aufrauhwerkzeug 4 besteht aus einem scheibenartigen resp. kreisförmigen Halter 8, in dessen Umfangsbereich stirnseitig vorstehende Bearbeitungskanten 9 angeordnet sind. Pfeil R weist in Fig. 2 auf eine der beiden möglichen Drehrichtungen hin.The roughening tool 4 connected to the drive shaft 6 of a motor 7 consists of a disk-like or. circular holder 8, in the circumferential region of which projecting processing edges 9 are arranged on the end face. Arrow R in FIG. 2 indicates one of the two possible directions of rotation.

Die vorstehenden Bearbeitungskanten 9 liegen in einer Schneidebene, welche mit der Bearbeitungsebene am Buchlockrücken einen flachen Anstellwinkel α bildet, so, dass die durch das beidseits über den Buchblockrücken hinausstehende Aufrauhwerkzeug 4 gebildeten Bearbeitungsabschnitte eines Kreises sich an der Drehachse gegenüberliegende Markierungen unterschiedlicher Bearbeitungstiefen aufweisen. Dabei weist jeweils der zu dem gleichen Bearbeitungskreis gehörende nachträgliche Bearbeitungs- resp. Markierungsabschnitt die grössere Tiefe im Buchblockrücken auf als der vorausgehende.
D.h. also, dass der in der aus der Drehachse des Aufrauhwerkzeuges 4 und der Fortbewegungsrichtung F des Buchblockes 3 gebildeten Ebene liegende Winkel, gebildet aus unaufgerauhtem Rückenabschnitt und der Drehachse des Aufrauhwerkzeuges, mehr als 90° beträgt.
Die als Schneidelemente ausgebildeten Bearbeitungskanten 9 können auch an der dem Buchblockrücken zugewendeten Stirnseite des Halters 8 befestigt sein.
Die Bearbeitungstiefe des Aufrauhwerkzeuges 4 beträgt maximal 1 mm.The protruding processing edges 9 lie in a cutting plane which forms a flat angle of attack α with the processing plane on the spine of the book lock, such that the roughening tool protrudes from the spine of the book block on both sides 4 formed machining sections of a circle have opposite markings of different machining depths on the axis of rotation. In this case, the subsequent processing or Marking section the greater depth in the spine of the book block than the previous one.
That is to say that the angle lying in the plane formed from the axis of rotation of the roughening tool 4 and the direction of travel F of the book block 3, formed from the unroughened back section and the axis of rotation of the roughening tool, is more than 90 °.
The processing edges 9 designed as cutting elements can also be fastened to the front side of the holder 8 facing the back of the book block.
The processing depth of the roughening tool 4 is a maximum of 1 mm.

Durch Abstimmen der Umfangsgeschwindigkeit und/oder der Anzahl der Bearbeitungskanten mit der Fortbewegungsgeschwindigkeit eines Buchblockes kann die Dichtheit der Markierungen am Buchblockrücken gewählt werden.The tightness of the markings on the back of the book block can be selected by coordinating the peripheral speed and / or the number of processing edges with the speed of travel of a book block.

Die Fig. 1 und 2 zeigen weiterhin die mögliche Kombination des Aufrauhwerkzeuges 4 mit einer ausserhalb dieses konzentrisch dazu angeordneten Ringbürste 12, die die aufgerauhte Oberfläche nachträglich von Staub und Spänen befreit. Die freien Borstenenden der gleich- oder gegensinnig um die Drehachse des Aufrauhwerkzeuges 4 angetriebenen Ringbürste 12 erreichen den Grund der Markierungen 10, 11.1 and 2 furthermore show the possible combination of the roughening tool 4 with an annular brush 12 arranged concentrically outside of it, which subsequently removes dust and chips from the roughened surface. The free bristle ends of the ring brush 12 driven in the same or opposite directions about the axis of rotation of the roughening tool 4 reach the bottom of the markings 10, 11.
