Description

Die Erfindung betrifft eine Vorrichtung zum Zuführen von Buchblocks in das Buchblocktransportsystem einer Klebebindemaschine gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a device for feeding book blocks into the book block transport system of an adhesive binding machine according to the preamble of patent claim 1.

In der DE 198 46 525 A1 ist eine Klebebindemaschine dargestellt und beschrieben mit einem Buchblocktransportsystem bestehend aus einer Vielzahl von in einer geschlossenen Umlaufbahn kontinuierlich bewegbaren und antriebsmäßig in gleichen gegenseitigen Abständen miteinander verbundenen Buchblockzangen zum Einspannen der als Blattstapel zugeführten Buchblocks, mit einer Einfuhr und einer Ausfuhr und mit einer Anzahl von Bearbeitungsstationen längs geradliniger Förderstrecken.In the DE 198 46 525 A1 an adhesive binding machine is shown and described with a book block transport system consisting of a plurality of continuously movable in a closed orbit and drivingly connected at equal mutual spacing book block pliers for clamping the supplied as a sheet stack book block, with an import and an export and with a number of processing stations along straight-line conveyor lines.

Aus der DE 34 42 560 C2 , die eine Vorrichtung nach dem Oberbegriff des Anspruchs 1 beschreibt, und der DE 34 45 928 C2 ist eine Zuführvorrichtung für das Buchblocktransportsystem bekannt, bestehend aus einer endlosen umlaufend angetriebenen Förderkette mit daran angeordneten die Buchblocks vorschiebenden Mitnehmerleisten, aus einer die aufrecht stehenden Buchblocks im Rücken stützenden Auflage und aus seitlichen Führungen. Der Antrieb der Förderkette ist mit dem Antrieb des Buchblocktransportsystems mechanisch gekoppelt. Die Buchblocks werden den Buchblockzangen entweder von schräg unten oder im Falle aufschwenkbarer Buchblockzangen höhengleich zugeführt. Für die nachfolgende Bearbeitung in der Klebebindemaschine ist eine positionsgenaue Aufnahme der Buchblocks in den Buchblockzangen erforderlich.From the DE 34 42 560 C2 , which describes a device according to the preamble of claim 1, and the DE 34 45 928 C2 a feeding device for the book block transport system is known, consisting of an endless circumferentially driven conveyor chain arranged thereon, the book blocks advancing entrainment, from a standing upright book block in the back supporting pad and side guides. The drive of the conveyor chain is mechanically coupled to the drive of the book block transport system. The book blocks are fed to the book block pliers either from diagonally below or in the case of swiveling book block pliers height equal. For the subsequent processing in the perfect binding machine a positionally accurate recording of the book block in the book block pliers is required.

Um Gleichlaufungenauigkeiten zwischen den Buchblockzangen des Buchblocktransportsystems und den Mitnehmerleisten der Zuführvorrichtung infolge ungleichmäßiger Kettenlängungen und Spiel in den Antriebsgliedern auszugleichen, weisen die Buchblockzangen jeweils einen Blockanschlag auf. Der zugeführte Buchblock wird von dem an der inneren Klemmbacke der Buchblockzangen angebrachten, mit der Umlenkbewegung der Buchblockzangen sich hinter den Buchblock bewegenden und in weiterer Förderbewegung die Mitnehmerleiste überholenden Blockanschlag von der Mitnehmerleiste übernommen und zur Buchblockzange ausgerichtet. Anschließend wird der Buchblock durch Schließen der Buchblockzange seitlich eingespannt.To compensate for inaccuracies inaccuracies between the book block tongs of the book block transport system and the entrainment of the feeder as a result of uneven chain elongations and play in the drive links, the book block tongs each have a block stop. The supplied book block is taken from the attached to the inner jaw of the book block pliers, with the deflection of the book block pliers behind the book block moving and in further conveying the catch rail overhauling block stop from the driver bar and aligned to the book block pliers. Then the book block is clamped laterally by closing the book block pliers.

Nachteilig ist, dass das Hineinschwenken des Blockeinschlags in den Strom von nacheinander zugeführten Buchblocks eine entsprechende Förderlücke erfordert, wodurch die maximale Formathöhe in Bezug auf die Teilung des Buchblocktransportsystems beschränkt ist. Durch die feste Anordnung der Blockanschläge an den Buchblockzangen ist eine hinterkantenfeste Positionierung der Buchblocks in den Buchblockzangen vorgegeben. Die sich dadurch ergebende außermittige Aufnahme der Buchblocks in den Buchblockzangen erfordert einen hohen konstruktiven Aufwand in der Führung und Kraftbeaufschlagung der äußeren Klemmbacke.The disadvantage is that the pivoting in of the block impact into the flow of successively fed book blocks requires a corresponding conveying gap, whereby the maximum format height is limited with respect to the pitch of the book block transport system. Due to the fixed arrangement of the block stops on the book block pliers, a trailing edge fixed positioning of the book block in the book block pliers is specified. The resulting eccentric recording of the book block in the book block pliers requires a lot of design effort in the leadership and force application of the outer jaw.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Zuführen eines Buchblocks nach dem Oberbegriff des Patentanspruchs 1 zu schaffen, die eine positionsgenaue Zuführung eines Buchblocks in die Buchblockzange ermöglicht.The invention has for its object to provide a device for feeding a book block according to the preamble of claim 1, which allows a positionally accurate supply of a book block in the book block pliers.

Diese Aufgabe wird erfindungsgemäß durch die Vorrichtung des Anspruchs 1 gelöst. Teilungstoleranzen und sonstige Ungenauigkeiten des Buchblocktransportsystems sowie des Fördermittels für die Zuführung der Buchblocks werden durch die Antriebsregelung des Fördermittels kompensiert. Die Buchblocks werden zur jeweiligen Buchblockzange ausgerichtet zugeführt, sodass eine Übernahme und Ausrichtung der Buchblocks durch Blockanschläge nicht mehr erforderlich ist. Die Blockanschläge an den Buchblockzangen können entfallen. Die durch die Blockanschläge begründeten, oben beschriebenen Beschränkungen lösen sich auf und es kann ein wesentlich größeres Formatspektrum bei gleicher Zangenteilung des Buchblocktransportsystems verarbeitet werden. Außerdem kann das Buchblocktransportsystem um die Übergabe- und Ausrichtstrecke gekürzt werden.This object is achieved by the device of claim 1. Graduation tolerances and other inaccuracies of the book block transport system and the conveyor for the supply of book blocks are compensated by the drive control of the conveyor. The book blocks are fed aligned to the respective book block pliers, so that a takeover and alignment of the book blocks by block stops is no longer required. The block stops on the book block pliers can be omitted. The limitations imposed by the block stops, as described above, are resolved, and a much wider range of formats can be processed with equal zipping of the book block transport system. In addition, the book block transport system can be shortened by the transfer and alignment path.

Die abhängigen Ansprüche definieren bevorzugte Weiterausgestaltungen der erfindungsgemäßen Zuführvorrichtung.The dependent claims define preferred further developments of the feeding device according to the invention.

Da es sich beim Einspannen aufgrund des elastischen Buchblocks um einen zeitlichen Vorgang handelt, ist es vorteilhaft, dass sich die betreffende Mitnehmerleiste zumindest während des Schließens synchron zur Buchblockzange bewegt. Die betreffende Mitnehmerleiste kann vor dem Schließen der Buchblockzange mit höherer oder langsamerer Geschwindigkeit als die betreffende Buchblockzange bewegt sein, um bspw. eine von der Zangenteilung abweichende Teilung der Mitnehmerleisten in dem Fördermittel auszugleichen. Die betreffende Mitnehmerleiste kann nach dem Schließen der Buchblockzange langsamer als die betreffende Buchblockzange bewegt sein, damit sich die Mitnehmerleiste von dem eingespannten Buchblock entfernt. Vorzugsweise ist die Teilung der Mitnehmerleisten gleich der Zangenteilung des Buchblocktransportsystems.Since it is a temporal process during clamping due to the elastic book block, it is advantageous that moves the respective driver bar at least during closing synchronously with the book block tongs. The respective catch bar can be moved before closing the book block pliers with higher or slower speed than the book block pliers in question, for example, to compensate for a deviating from the Zangenteilung pitch of the entrainment in the conveyor. The respective catch bar can be moved after closing the book block pliers slower than the book block pliers in question, so that the carrier strip removed from the clamped book block. Preferably, the pitch of the entrainment is equal to the Zangenteilung the book block transport system.

Das Fördermittel kann nach einer festlegbaren Position der Buchblocks in den Buchblockzangen gesteuert bzw. veränderbar gesteuert sein. Der Buchblock kann damit an einer beliebigen Stelle in der Buchblockzange eingespannt werden. Vorzugsweise werden die Buchblocks bezüglich ihrer sich in Zuführförderrichtung erstreckenden Formathöhe mittig in den Buchblockzangen zugeführt und eingespannt, wodurch sich eine symmetrische Beanspruchung der Buchblockzangen ergibt, die hinsichtlich der Führung und Kraftbeaufschlagung der äußeren bewegbaren Klemmbacke eine wesentlich einfachere konstruktive Gestaltung der Buchblockzangen ermöglicht.The conveying means can be controlled or variably controlled according to a definable position of the book blocks in the book block tongs. The book block can thus be clamped anywhere in the book block tongs. Preferably, the book blocks are fed and clamped centrally in the book block pliers with respect to their Formathöhe extending in Zuführförderrichtung, resulting in a symmetrical stress of the book block pliers, which allows a much simpler design of the book block pliers with respect to the guidance and force application of the outer movable jaw.

Die Referenzierung erfolgt bei jeder Buchblockzange 12 bzw. 13, um mögliche Abweichungen in den Abständen zwischen den einzelnen Buchblockzangen 12 bzw. 13 zu erfassen.The motor controller 30 of the servomotor 28 is for this purpose connected to a higher-level controller 20, in which the actual position of the respective book block tongs 12 and 13 is calculated according to the signal of the arranged on the drive wheel 15 of the book block transport system 11.1 and 11.2 rotary encoder 18, wherein the position calculation of a reference position is carried out, which is in each case set by a light barrier 19 reacting to a reference edge of the book block pliers 12 and 13 immediately before. Rotary encoder 18 and light barrier 19 thus form the measuring system for determining the position of the respective book block pliers 12 and 13, respectively. Referencing takes place at each book block pliers 12 and 13 in order to detect possible deviations in the distances between the individual book block pliers 12 and 13.

Aus gleichem Grund ist in der Zuführvorrichtung 21.1 bzw. 21.2 zusätzlich zur Resolverrückführung 28 a des Servomotors 28 eine Lichtschranke 29 vorgesehen, welche quasi die jeweils zugeordnete Mitnehmerleiste 25 referenziert. Resoverrückführung 28 a und Lichtschranke 29 bilden das Messsystem zur Positionsermittlung der betreffenden Mitnehmerleiste 25.For the same reason, a light barrier 29 is provided in the feeder 21.1 or 21.2 in addition to the resolver return 28 a of the servomotor 28, which quasi the referenced each Mitnehmerleiste 25 referenced. Reso feedback 28 a and light barrier 29 form the measuring system for determining the position of the respective carrier strip 25.

Die Förderkette 22 wird dann vom Servoantrieb 28 derart gesteuert angetrieben, dass ein von der Mitnehmerleiste 25 vorgeschobener Buchblock 2 in vordefinierter Lage zur kontinuierlich bewegten Buchblockzange 12 bzw. 13 gelangt. Eine Übernahme und Ausrichtung der Buchblocks 2 durch Blockanschläge an den Buchblockzangen 12 bzw. 13 ist nicht mehr erforderlich, weshalb in den Figuren die Buchblockzangen 12 und 13 auch keine solchen Blockanschläge mehr aufweisen. Die Mitnehmerleiste 25 kann unterhalb der Klemmbacken 12 a, 12 b bzw. 13 a, 13 b bewegt werden, wobei sie den Kopf des Buchblocks im Bereich seines Aushanges aus der Buchblockzange kontaktiert.The conveyor chain 22 is then driven in a controlled manner by the servo drive 28 in such a way that a book block 2 advanced from the entrainment bar 25 reaches the continuously moving book block tongs 12 or 13 in a predefined position. A takeover and alignment of the book block 2 by block stops on the book block pliers 12 and 13 is no longer necessary, which is why in the figures, the book block pliers 12 and 13 have no such block stops more. The carrier strip 25 can be moved below the jaws 12 a, 12 b and 13 a, 13 b, wherein it contacts the head of the book block in the region of his notice from the book block pliers.

Die erfindungsgemäße Zuführvorrichtung 21.1 bzw. 21.2 ermöglicht die beliebige, insbesondere aber mittige Einspannung der Buchblocks 2 in den Buchblockzangen 12 bzw. 13, wie dies in den Figuren 3 a und 3 b anhand der für die Buchblockzange 12 bzw. 13 und dem Buchblock 2 gemeinsamen Mittellinie M ersichtlich wird. Die sich dadurch ergebende symmetrische Beanspruchung der Buchblockzangen 12 bzw. 13 ermöglicht eine hinsichtlich der Führung und Kraftbeaufschlagung der äußeren bewegbaren Klemmbacke 12 c bzw. 13 c wesentlich einfachere konstruktive Gestaltung der Buchblockzangen 12 und 13.The feeding device 21.1 or 21.2 according to the invention allows any, but especially central clamping of the book block 2 in the book block pliers 12 and 13, as shown in the Figures 3 a and 3 b will be apparent from the common for the book block tongs 12 and 13 and the book block 2 center line M. The thus resulting symmetrical stress of the book block pliers 12 and 13 allows a respect to the leadership and Kraftbeaufschlagung the outer movable jaw 12 c and 13 c much simpler structural design of the book block pliers 12 and 13th

Die betreffende Mitnehmerleiste 25 kann vor dem Schließen der Buchblockzange 12 bzw. 13 mit höherer oder langsamerer Geschwindigkeit als die betreffende Buchblockzange 12 bzw. 13 bewegt sein, um bspw. eine von der Zangenteilung abweichende Teilung der Mitnehmerleisten 25 in der Zuführvorrichtung 21.1 bzw. 21.2 auszugleichen. In den beiden Ausführungsbeispielen ist die Teilung der Mitnehmerleisten 25 gleich der Zangenteilung des Buchblocktransportsystem 11.1 bzw. 11.2. Die betreffende Mitnehmerleiste 25 kann nach dem Einspannen des Buchblocks 2 langsamer als die betreffende Buchblockzange 12 bzw. 13 bewegt werden, damit sich die Mitnehmerleiste 25 von dem eingespannten Buchblock 2 entfernt. Da es sich beim Einspannen aufgrund des elastischen Buchblocks 2 um einen zeitlichen Vorgang handelt, ist zumindest über dieses Zeitraum vorgesehen, dass sich die betreffende Mitnehmerleiste 25 synchron zur Buchblockzange 12 bzw. 13 bewegt.The respective driver bar 25 can be moved 12 or 13 before closing the book block pliers 12 and 13 at a higher or slower speed than the book block pliers concerned, for example, to compensate for a deviating from the Zangenteilung division of Mitnehmerleisten 25 in the feeder 21.1 and 21.2 , In the two embodiments, the pitch of the Mitnehmerleisten 25 is equal to the Zangenteilung the book block transport system 11.1 and 11.2. The respective driver bar 25 can be moved after clamping of the book block 2 slower than the relevant book block pliers 12 and 13, so that the driver bar 25 away from the clamped book block 2. Since it is a temporal process during clamping due to the elastic book block 2, at least over this period, it is provided that the respective driver bar 25 moves synchronously with the book block pliers 12 and 13, respectively.

In den Ausführungsbeispielen weisen die erfindungsgemäßen Zuführvorrichtungen 21.1 und 21.2 einen vom Antrieb des Buchblocktransportsystems 11.1 bzw. 11.2 separaten Antrieb auf. Eine erfindungsgemäße Zuführvorrichtung lässt sich aber auch darüber realisieren, dass der Antrieb der Förderkette 22 ein Überlagerungsgetriebe umfasst, mit einer mechanischen Antriebsverbindung zum Antrieb des Buchblocktransportsystems am ersten Eingang und einem von einer Steuervorrichtung steuerbaren Antriebsorgan am zweiten Eingang.In the exemplary embodiments, the feed devices 21.1 and 21.2 according to the invention have a drive separate from the drive of the book block transport system 11.1 or 11.2. However, a feed device according to the invention can also be realized that the drive of the conveyor chain 22 comprises a superposition gear, with a mechanical drive connection for driving the book block transport system at the first input and a controllable by a control device drive member at the second input.
