Eine Fördereinrichtung für Buchbindemaschinen nach der DE 199 26 407 A1 besitzt eine Anzahl Bearbeitungsstationen entlang von die Buchblocks fördernden, umlaufenden Stollenketten.A conveyor for bookbinding machines after the DE 199 26 407 A1 has a number of workstations along the perimeter blocks conveying the book blocks.

Nach der DE 22 64 336 A ist eine Buchbinde-Anlage bekannt, in der klebegebundene Bücher einer Abrichtmaschine für das Beschneiden der ungebundenen Seitenkanten zugeführt werden. Entlang der Zuführstrecke sind den Seitenkanten der Bücher zugeordnete Messfühler angeordnet, die die relative Stellung der Sägebänder zu den Buchkanten bestimmen.After DE 22 64 336 A a bookbinding system is known in which bound books are fed to a dressing machine for trimming the unbonded side edges. Along the feed path sensors are assigned to the side edges of the books, which determine the relative position of the saw bands to the book edges.

Die GB 830 681 vermittelt eine Buchbindemaschine, bei welcher die Bücher nacheinander zwischen zwei Förderriemen mit dem Buchrücken aufliegend gefördert werden, wobei am Abgabeende eines Hauptförderers ein mit höherer Geschwindigkeit laufender Hilfsförderer und ein Stapelkopf, auf den die Bücher einzeln auflaufen, vorgesehen ist,The GB 830,681 mediates a bookbinding machine, in which the books are successively conveyed lying between two conveyor belts with the spine, wherein at the discharge end of a main conveyor a running at a higher speed auxiliary conveyor and a stacking head, on which the books accumulate individually, is provided

Es stellt sich an die Erfindung die Aufgabe vor einem weiteren Verarbeitungsschritt eine Kontrolle über die Vollständigkeit eines Buchblockes durchführen zu können, ohne dass dadurch eine Verlängerung einer Verarbeitungsstrecke mehrerer Verarbeitungsstationen entsteht, indem einerseits die tatsächlichen Dickenwerte der Buchblocks bereitgestellt und andererseits die Transportqualität durch Erzeugung eines weitgehend regelmäßigen Reibungskontakts mit den Buchblocks verbessert werden.It is an object of the invention to be able to carry out a check on the completeness of a book block without further extending a processing path of a plurality of processing stations, on the one hand providing the actual thickness values of the book blocks and, on the other hand, largely ensuring the transport quality by generating one regular friction contact with the book block can be improved.

Erfindungsgemäss wird die Aufgabe durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst.According to the invention, the object is achieved by the characterizing features of patent claim 1.

Zur Optimierung des Transportes der Buchblocks erweist es sich als günstig, wenn wenigstens einer Transportrolle eine Umlenkrolle zugeordnet ist, die gemeinsam mit einem endlos umlaufenden Zugorgan einen auf die Seitenflächen eines Buchblocks einwirkenden Arbeitstrum bilden, sodass ein zuverlässiger resp. günstiger Reibungskontakt mit dem Buchblock entstehen kann.To optimize the transport of the book block, it proves to be advantageous if at least one transport roller is associated with a guide roller, which form together with an endlessly circulating pulling member acting on the side surfaces of a book block Arbeitstrum, so that a reliable resp. favorable frictional contact with the book block can arise.

Wenn dabei die Transportrollen jeweils an einem federbelasteten Lenkergelagert sind, kann ein weiti gehend regelmässiger Reibungskontakt mit den Buchblocks entstehen.If in this case the transport rollers are each mounted on a spring-loaded handlebar, a far-reaching regular frictional contact with the book block can arise.

Vorteilhaft erweist sich eine Einrichtung, bei der die Umlenkrolle an einem konzentrisch zur Transportrolle gelagerten Hebel schwenkend verstell- und feststellbar ist, sodass das Arbeitstrum gegenüber der Richtung des Förderkanals (leicht) verstellt werden kann.Advantageously, a device in which the deflection roller is pivotally adjustable and lockable on a lever mounted concentrically to the transport roller, so that the working strand can be adjusted (easily) with respect to the direction of the conveying channel.

Vorzugsweise sind die Transportrollen in einer als Messwertaufnehmer ausgebildeten Messvorrichtung angeordnet, sodass eine kompakte Bauweise der den Transport und die Dickenmessung der Buchblocks vereinigenden Einrichtung erreicht werden kann.Preferably, the transport rollers are arranged in a measuring device designed as a measuring device, so that a compact design of the transport and the thickness measurement of the book blocks unit can be achieved.

Zur Messung resp. Kontrolle der Dicke eines Buchblockes kann die Messvorrichtung einen die Transportrollen verbindenden Wegsensor aufweisen, der auf einer elektrischen, optischen oder elektromagnetischen Basis aufgebaut ist.For measurement resp. Checking the thickness of a book block, the measuring device may have a displacement sensor connecting the transport rollers, which is constructed on an electrical, optical or electromagnetic base.

Solche und andere Potentiometer sind beispielsweise bei der Gefran GmbH, DE-63500 Seligenstadt erhältlich.As expedient proves, for example, a linear potentiometer, which is mounted between the transport rollers and is designed to be telescopically movable. Such and other potentiometers are for example at Gefran GmbH, DE-63500 Seligenstadt available.

Der einfachheithalber sind die Transportrollen jeweils in einem durch den Wegsensor verbundenen Support gelagert.The sake of simplicity are the transport wheels each stored in a connected by the displacement sensor support.

An dem Support ist vorteilhaft eine senkrechte Stange befestigt, an deren unterem Ende eine Halterung zur einseitigen Befestigung des Wegsensors vorgesehen ist.On the support a vertical rod is advantageously attached, at the lower end of a holder for one-sided attachment of the displacement sensor is provided.

Als einfach erweist sich eine Ausführungsform, bei der das freie Ende des schwenkbaren Lenkers durch den Support ausgebildet ist.As simple proves an embodiment in which the free end of the pivotable arm is formed by the support.

Bei einer Aenderung der Dicke der Buchblocks ist es erforderlich, dass die Transportrollen und die ihr zugeordneten Betätigungs- und Antriebselemente auf einerrechtwinklig zur Förderrichtung (F) des Förderkanals verschiebbaren Konsole befestigt sind.In a change in the thickness of the book block, it is necessary that the transport rollers and their associated actuation and drive elements are mounted on a perpendicular to the conveying direction (F) of the conveyor channel sliding console.
