Description

Die Erfindung betrifft eine Vorrichtung gemäss Oberbegriff des Patentanspruches 1. Eine solche Vorrichtung wird beispielsweise in der Patentschrift GB-A-2 096 945 beschrieben.The invention relates to a device according to the preamble of claim 1. Such a device is described for example in the patent specification GB-A-2 096 945.

Zur Verbesserung der Stabilität und Haltbarkeit eines Buches wird vor der Beleimung des Buchblockrückens durch das Anbringen von etwa quer zu den Seiten- oder Falzkanten verlaufenden Kerben eine Vergrösserung der Blattkantenfläche bezweckt. Diese Bearbeitung erfordert einen hohen Kraftaufwand und beansprucht eine Buchbindeanlage erheblich.In order to improve the stability and durability of a book, the purpose of the book edge is to enlarge the surface of the sheet edge by making notches running transversely to the side or fold edges. This processing requires a great deal of effort and places considerable stress on a bookbinding system.

Dabei führt ein unstabiler Buchblockaushang zu ungenauer Masshaltigkeit und wirkt sich qualitätsmindernd auf das herzustellende Produkt aus.An unstable book block display leads to imprecise dimensional accuracy and has a quality-reducing effect on the product to be manufactured.

Die bislang verwendeten sationären seitlichen Abstützvorrichtungen für den Buchblockaushang hinterliessen aufgrund hoher Reibungskräfte schädliche Marken wie Schürfspuren oder Rumpfbildungen. Zudem musste die Abstützvorrichtung nach einer bestimmten Zeit wegen Abnützung nachgestellt oder ausgewechselt werden.The stationary side supports previously used for the book block notice left behind harmful marks such as grazes or fuselages due to high frictional forces. In addition, the support device had to be readjusted or replaced after a certain time due to wear.

Bekanntlich werden beim Beschneiden von Buchblockrücken mit sog. Kreismessern beidseits des Buchblockaushanges rotierende Pressrollen als Gegenhalter verwendet, die den Buchblockaushang aufgrund der annähernd bündigen Schnittebene abzustützen vermögen.As is known, when trimming book block spines with so-called circular knives, rotating press rollers are used as counterholders on both sides of the book block display, which are able to support the book block display due to the approximately flush cutting plane.

Bei der Herstellung von Kerben bedarf es jedoch zumindest eines Buchblock-Aushanges der Tiefe der Kerben, wobei die Verwendung der bekannten Pressrollen wegen unstabiler Führung zu Ungenauigkeiten und Beschädigungen an den Rücken der Buchblöcke führen würde.In the production of notches, however, at least one book block notice of the depth of the notches is required, the use of the known press rollers, because of the unstable guidance, leading to inaccuracies and damage to the back of the book blocks.

Aufgabe der vorliegenden Erfindung ist es somit, eine Vorrichtung zu schaffen, mit welcher der Rücken eines Buchblockes derart bearbeitet werden kann, dass die den Gegenhalter passierenden Bogen nicht beschädigt und der Verschleiss am Gegenhalter weitgehend verhindert werden kann, ohne dass dadurch eine Qualitätseinbusse am Buchblock entsteht.It is therefore an object of the present invention to provide a device with which the spine of a book block can be processed in such a way that the sheets passing through the counter holder cannot be damaged and wear on the counter holder can be largely prevented without any loss of quality in the book block .

Erfindungsgemäss wird diese Aufgabe nach den Merkmalen des kennzeichnenden Teils des Patentanspruches 1 gelöst. Hierzu eignen sich die bekannten rotierenden Kerbwerkzeuge.This object is achieved according to the features of the characterizing part of patent claim 1. The known rotating notching tools are suitable for this.

Bei Anwendung eines in einer zum Buchblockrücken parallelen Ebene rotierend angetriebenen Kerbwerkzeuges oder eines Walzenfräsers verlaufen die Nuten in der Führung etwa parallel zum eingespannten Buchblockrücken, währenddem die eine Nut bei Verwendung eines rotierenden Kerbwerkzeuges zusätzlich die Form eines Kreisabschnittes aufweist.When using a notching tool or a milling cutter, which is driven to rotate in a plane parallel to the book block spine, the grooves in the guide run approximately parallel to the clamped book block spine, while the one groove is at Using a rotating notching tool also has the shape of a circular section.

Der Gegenhalter ist zweckmässig frei drehbar ausgebildet, kann aber auch mit der Geschwindigkeit der Buchblöcke angetrieben sein.The counterholder is expediently freely rotatable, but can also be driven at the speed of the book blocks.

Zur Anhebung der Zuverlässigkeit und Genauigkeit beim Kerben mittels einer zum eingespannten Buchblockrücken parallel verlaufenden kreisförmigen Bewegungsbahn des Werkzeuges, ist vorzugsweise die Bewegungsbahn als Nut in einer gegenüber der zylindrischen Stützfläche zurückversetzten Führungsplatte ausgebildet.To increase the reliability and accuracy when notching by means of a circular movement path of the tool running parallel to the clamped book block spine, the movement path is preferably designed as a groove in a guide plate set back relative to the cylindrical support surface.

Damit in der Nähe des Rückens auf den Buchblock ein relativ hoher Druck erzeugt werden kann, ist es vorteilhaft, wenn die zylindrische Stützfläche als vorstehende Scheibe eines um eine zur Bearbeitungsebene etwa senkrecht gelagerten Rotationskörpers ausgebildet ist.So that a relatively high pressure can be generated in the vicinity of the spine on the book block, it is advantageous if the cylindrical support surface is designed as a protruding disk of a rotating body which is approximately perpendicular to the working plane.

Um zwischen zylindrischer Stützfläche und Schnittebene des Kerbwerkzeuges einen geringen Abstand erzielen zu können, ist es zweckmässig, wenn der stirnseitige Rand des Gegenhalters an der Führungsplatte gleitend ausgebildet und zum Nutboden bedarfsfalls ein geringer Abstand vorgesehen ist.In order to be able to achieve a small distance between the cylindrical support surface and the cutting plane of the notching tool, it is expedient if the end edge of the counter-holder is designed to slide on the guide plate and if necessary a small distance is provided from the groove bottom.

Dadurch, dass die Führungsplatte bei einstückiger Ausbildung aufgrund des in die Nut eintauchenden Kerbwerkzeuges relativ dünn ausgebildet ist und sich somit zur Belastung durch den Gegenhalter nicht besonders eignet, ist es günstig, wenn der Gegenhalter an einer in einem Träger einseitig befestigten Welle gelagert ist.Due to the fact that the guide plate, in the case of a one-piece design, is relatively thin due to the notching tool which dips into the groove and is therefore not particularly suitable for loading by the counter-holder, it is advantageous if the counter-holder is mounted on a shaft fixed on one side in a carrier.

Zur Anpassung des Gegenhalters an den Buchblockaushang ist letzterer vorzugsweise verstellbar ausgebildet.To adapt the counter holder to the book block notice, the latter is preferably designed to be adjustable.

Zur Einhaltung einer optimalen Massgenauigkeit ist die Lagerwelle an dem dem Befestigungsende gegenüberliegenden Ende in der Führungsplatte axial geführt.In order to maintain optimum dimensional accuracy, the bearing shaft is axially guided in the guide plate at the end opposite the fastening end.

Der die Befestigung der Lagerwelle bildende Träger ist zur Bildung eines einfachen, stabilen Elementes mit der Führungsplatte verbunden.The support forming the mounting of the bearing shaft is connected to the guide plate to form a simple, stable element.

Die Führungsplatte kann zum Zweck des Auswechselns von Verschleisspartien mehrteilig ausgebildet sein.The guide plate can be designed in several parts for the purpose of replacing wear parts.

Hierzug sind vorzugsweise eine Grundplatte und zwei mit dieser lösbar verbundene Sockelteile vorgesehen, die auf einfache Art ersetzbar sind.For this purpose, a base plate and two base parts releasably connected to it are preferably provided, which can be replaced in a simple manner.

Die Sockelleisten bilden vorteilhaft das dem Aushang zugewendete Ende der Führungsplatten.The skirting boards advantageously form the end of the guide plates facing the notice board.

Further advantages and details of the invention result from the following description of an exemplary embodiment with reference to the drawing. In this shows:

Die Fig. 1 bis 3 zeigen eine Vorrichtung 1 für eine Buchbindemaschine zur Herstellung von klebeweise an den Rücken gebundenen Büchern oder Broschüren, bei denen die Buchblöcke 2 an ihren Rücken 3 etwa quer zu den Seiten- oder Falzkanten verlaufende Kerben 4 aufweisen, die vornehmlich durch spanende Dreh- oder Fräswerkzeuge 5 erzeugt werden. Zu diesem Zweck liegt der an der Unterseite der zweiteiligen Einspannvorrichtung 6 vorstehende Aushang 7 eines Buchblockes 2 seitlich an einem Gegenhalter 8 an, der den Aushang 7 gegen die Schnittkraft des Werkzeuges 5 und das Auseinanderklaffen der Blattkanten abstützt.
Hierzu ist der auf den Aushang 7 einwirkende Gegenhalter 8 mit einer drehbaren zylindrischen Stützfläche 9 ausgestattet, die durch Friktion mit dem Aushang 7 antriebsverbunden ist, jedoch auch mit gleicher Geschwindigkeit wie die Buchblöcke 2 angetrieben sein könnte. Der antreibbare Gegenhalter 8 ist oberhalb einer die Bewegungsbahn des Kerbwerkzeuges 5 seitlich umgebenden Nut 10 angeordnet, wobei letztere in einer gegenüber dem Buchblock von der zylindrischen Stützfläche 9 zurückversetzten Führungsplatte 11, die wie dargestellt auch aus mehreren Teilen 12, 13, 14 bestehen kann, angeordnet ist. Ist die Führungsplatte einstückig ausgebildet, so bedarf es eines grösseren Aushanges 7, um die beabsichtigte Kerbtiefe erzielen zu können, und einer seitlichen Verstärkung der Führungsplatte 11.
In der gezeigten Ausführungsform weist die Führungsplatte 11 jedoch eine Grundplatte 12 und daran befestigte Sockelteile 13 und 14 auf, die keilartig an der Grundplatte 12 aufgesetzt und mittels Schraube 15 befestigt sind. Die durch die Ausnehmung 16 entlang der Bewegungsbahn des Kerbwerkzeuges entstehende Zweiteiligkeit der Grundplatte 12 bedingt, dass Grundplatteteil 17 an einem festen, mit dem Ständer der Buchbindemaschine verbundenen Adapter 18 befestigt ist.1 to 3 show a device 1 for a bookbinding machine for the production of books or brochures which are adhesively bonded to the back, in which the book blocks 2 have notches 4 on their backs 3 which run approximately transversely to the side or fold edges, primarily through Metal turning or milling tools 5 are generated. For this purpose, the notch 7 on the underside of the two-part jig 6 of a book block 2 laterally abuts a counter-holder 8, which supports the notch 7 against the cutting force of the tool 5 and the gaping of the sheet edges.
For this purpose, the counter-holder 8 acting on the display 7 is equipped with a rotatable cylindrical support surface 9 which is frictionally connected to the display 7 but could also be driven at the same speed as the book blocks 2. The drivable counter-holder 8 is arranged above a groove 10 which laterally surrounds the movement path of the notching tool 5, the latter being arranged in a guide plate 11 set back from the cylindrical support surface 9 relative to the book block, which, as shown, can also consist of several parts 12, 13, 14 is. If the guide plate is formed in one piece, a larger notch 7 is required to achieve the intended notch depth and a lateral reinforcement of the guide plate 11.
In the embodiment shown, however, the guide plate 11 has a base plate 12 and base parts 13 and 14 fastened thereon, which are placed in a wedge-like manner on the base plate 12 and fastened by means of screw 15. The two-part nature of the base plate 12 that results from the recess 16 along the movement path of the notching tool means that the base plate part 17 is fastened to a fixed adapter 18 connected to the stand of the bookbinding machine.

Letzterer kann bspw. an dem die Lagerwelle 19 des Gegenhalters 8 aufnehmenden Träger 20, der seinerseits mit dem Maschinenständer verbunden ist, angebaut sein.
Wird, wie in den Fig. 1 und 2 erkennbar, ein parallel zum Buchblockrücken 3 rotierendes Kerbwerkzeug 5 verwendet, dann verläuft die Ausnehmung 16 für die Bewegungsbahn des rotierenden Kerbwerkzeuges 5, dessen Drehachse etwa senkrecht zum Buchblockrücken fest angeordnet ist, nach einem Kreisabschnitt gemäss den gestrichelten Linien 30 in Fig. 2.
Darin liegt u.a. der Grund, der zur Mehrteiligkeit der Führungsplatte 11 führt.
Bei Benutzung von Walzenfräsern, die von unten gegen den Buchblockrücken bewegt werden, ist es vorteilhaft, wenn diese mit der Fortbewegungsgeschwindigkeit des Buchblockes, also während dem Fräsvorgang mitlaufend und in ihre Ausgangslage zurückversetzbar angetrieben sind.The latter can, for example, be attached to the support 20 which receives the bearing shaft 19 of the counter-holder 8 and which in turn is connected to the machine stand.
If, as can be seen in FIGS. 1 and 2, a notch tool 5 rotating parallel to the book block spine 3 is used, then the recess 16 for the movement path of the rotating notch tool 5, the axis of rotation of which is arranged approximately perpendicular to the book block spine, runs according to a circular section according to FIGS dashed lines 30 in FIG. 2.
This is one of the reasons why the guide plate 11 has multiple parts.
When using milling cutters that are moved against the back of the book block from below, it is advantageous if they are driven at the speed of travel of the book block, that is to say during the milling process, and are driven back to their initial position.

Der rotierende Gegenhalter 8 weist eine pyramideähnlich gestufte kreisförmige Querschnittsform auf und ist an seinem Umfang mit einer zylindrischen bzw. scheibenartigen Stützfläche 9 versehen. Die beiden stirnseitigen Enden des Gegenhalters 8 sind mit halsähnlichen Ansätzen 21, 22 ausgebildet, die in eine gegenüberliegende Vertiefung eintauchend eine labyrinthartige Dichtung gegen Staub bzw. Späne bilden.The rotating counter-holder 8 has a circular cross-sectional shape stepped like a pyramid and is provided on its circumference with a cylindrical or disk-like support surface 9. The two front ends of the counter-holder 8 are formed with neck-like projections 21, 22 which, when immersed in an opposite depression, form a labyrinth-like seal against dust or chips.

Am Rand der der Führungsplatte 11 zugewendeten Stirnseite des Gegenhalters 8 ist eine ringförmige Gleitfläche vorgesehen, die an der Führungsplatte 11 anliegt. Die zum Buchblockrücken 3 senkrecht stehende Lagerwelle 19 ist von einer in dem Träger 20 festsitzenden Schraube 23 axial durchsetzt und in diesem einseitig verankert, wogegen das andere Ende der Lagerwelle 19 in einer Durchtrittsöffnung der Führungsplatte 11 geführt ist. Zur Lagerung des Gegenhalters 8 sind zwei Nadellager 24 vorgesehen.At the edge of the end face of the counter-holder 8 facing the guide plate 11, an annular sliding surface is provided which bears against the guide plate 11. The bearing shaft 19, which is perpendicular to the spine of the book block 3, is axially penetrated by a screw 23 fixed in the carrier 20 and anchored in it on one side, whereas the other end of the bearing shaft 19 is guided in a passage opening of the guide plate 11. Two needle bearings 24 are provided for mounting the counter holder 8.

In der Fig. 1 ist eine Einspannvorrichtung 27 veranschaulicht, die eine das Kerbwerkzeug 5 an einem Halter 26 festklemmende Schraube 25 und Unterlagsscheiben 28 aufweist. Das Kerbwerkzeug 5 ist bspw. als eine am Umfang Schneidzähne aufweisende Scheibe, die jeweils nach reduzierter Schneidwirkung drehverstellt werden kann, oder als ähnliches spanendes Werkzeug ausgebildet.1, a clamping device 27 is illustrated which has a screw 25 and washer 28 which clamps the notching tool 5 on a holder 26. The notching tool 5 is designed, for example, as a disk having cutting teeth on the circumference, which can be rotated in each case after a reduced cutting action, or as a similar cutting tool.
