Description

Die Erfindung betrifft eine Vorrichtung zum Zuführen von einzelnen oder gestapelten Falzbogen, Buchblocks, Büchern oder dgl. Druckprodukten zu einer Weiterverarbeitungsmaschine, mit einem Zuführförderer, auf dem die Druckprodukte aufeinander folgend transportiert werden, mit einer am stromabwärtigen Ende des Zuführförderers angeordneten Sperre zur getakteten Freigabe einzelner Druckprodukte bzw. -stapel.The invention relates to a device for feeding individual or stacked signatures, book blocks, books or the like. Printed products to a finishing machine, with a feed conveyor on which the printed products are transported sequentially, with a arranged at the downstream end of the feed conveyor lock for individual release Printed products or piles.

Eine Zuführeinrichtung für Buchblocks und Bücher ist in der DD 203 279 B beschrieben und dargestellt. Auf einem Förderband flachliegend zugeführte Buchblocks werden von der Sperre solange gestoppt, bis die Freigabe zur taktgemäßen Weiterförderung in der Weiterverarbeitungsmaschine erfolgt. Die Weiterförderung erfolgt mit einer höheren Fördergeschwindigkeit als die Zuförderung, sodass sich zwischen den beiden vorderen, ggf. auf dem Förderband noch aneinander liegenden Buchblocks eine Lücke zum Schließen der Sperre ergibt. Bei einer in der DE 10 2004 019 756 A1 dargestellten Zuführeinrichtung für Bücher wird die Lückenbildung noch durch eine schaltbare Rückhalteeinrichtung für das nachfolgende Buch unterstützt.A feeder for book blocks and books is in the DD 203 279 B described and illustrated. On a conveyor belt lying flat supplied book blocks are stopped by the lock until the release of the clockwise further promotion takes place in the finishing machine. The further promotion is carried out at a higher conveying speed than the feed, so that there is a gap between the two front, possibly still lying on the conveyor belt book block to close the lock. At one in the DE 10 2004 019 756 A1 shown feeding device for books, the gap formation is still supported by a switchable restraint device for the subsequent book.

Die DE 42 27 478 A1 zeigt eine Vereinzelungseinrichtung für Buchblockstapel, die von einem Zuführförderer zu einer Entstapelstelle transportiert werden, wobei sich zwischen dem Zuführförderer und der Entstapelstelle eine Beschleunigungsrolle mit einer zugeordneten, schwenkbaren Gegendruckrolle befindet mit der Aufgabe den vorderen Buchblockstapel vom nachfolgenden wegzuziehen, um eine Lücke für eine hineinsteuerbare Sperre zum Zurückhalten eines nachfolgenden Stapels zu schaffen.The DE 42 27 478 A1 shows a book block stack singulator conveyed by a infeed conveyor to a destacking station with an acceleration roller with an associated pivotable counterpressure roller between the infeed conveyor and the destacking station, with the task of pulling the front book block stack away from the next to create a gap for an inrushable barrier to provide for the retention of a subsequent stack.

Es sind außerdem Zuführeinrichtungen mit taktgemäß ansteuerbaren Sperren bekannt, bei denen die Druckprodukte bzw. -stapel stehend, von seitlichen Führungen gestützt einer Weiterverarbeitungsmaschine zugeführt werden.There are also feeding devices with clockwise controllable locks are known in which the printed products or stacks are supported by lateral guides supported by a further processing machine.

Nachteilig bei den bekannten Zuführungseinrichtungen ist, dass insbesondere bei höheren Fördergeschwindigkeiten die gegen die geschlossene Sperre laufenden Druckprodukte bzw. -stapel von der Sperre zurückprallen und durch den Zuführförderer erneut gegen die Sperre gefördert werden müssen. Dabei kann es passieren, dass die Druckprodukte bzw. -stapel eine verdrehte, für die Weiterverarbeitung kritische Lage einnehmen. Produktstapel können ihre Stapelordnung verlieren. Auch können die Druckprodukte bzw. -stapel durch das Zurückprallen und Nachfördern verspätet an der mittlerweile taktgemäß geöffneten Sperre eintreffen, sodass eine taktgenaue Zuführung in die Weiterverarbeitungsmaschine nicht mehr gegeben ist. Durch den Einsatz von Schleppfedern oder Bürsten soll ein Zurückprallen unterdrückt werden. Deren Bremswirkung wirkt jedoch auch beim Vorlaufen gegen die Sperre auf die Druckprodukte bzw. -stapel. Sie sind daher sensibel in ihrer Einstellung und können leichte Druckprodukte bzw. -stapel derart ausbremsen, dass diese die Sperre nicht mehr oder zu spät erreichen.A disadvantage of the known feeding devices is that, in particular at higher conveying speeds, the products running against the closed barrier printed products or stack bounce back from the barrier and must be promoted again by the feed conveyor against the lock. It can happen that the printed products or stacks take a twisted, critical for further processing position. product stack can lose their stacking order. Also, the printed products or stacks can arrive late due to the rebounding and Nachfördern at the meantime clockwise open lock, so that a precise timing feed into the finishing machine is no longer given. The use of drag springs or brushes to suppress rebounding. Their braking effect, however, also acts in the run against the barrier on the printed products or stacks. They are therefore sensitive in their attitude and can slow down light printed products or piles in such a way that they no longer reach the barrier or too late.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Zuführen von einzelnen oder gestapelten Falzbogen, Buchblocks, Büchern oder dgl. Druckprodukten zu einer Weiterverarbeitungsmaschine gemäß dem Oberbegriff des Anspruchs 1 derart zu verbessern, dass bei einfacher Konstruktion ein einwandfreies Zuführen der Druckprodukte bzw. -stapel auch bei hoher Fördergeschwindigkeit ermöglicht wird.The invention has for its object to improve a device for feeding individual or stacked signatures, book block, books or the like. Printed products to a further processing machine according to the preamble of claim 1 such that with a simple design proper feeding of the printed products or stacks even at high conveying speed is made possible.

Diese Aufgabe wird erfindungsgemäß gelöst, durch wenigstens eine in Transportrichtung hinter der Sperre angeordnete, eine Rücklaufsperre entgegen der Transportrichtung aufweisende Druckrolle. Durch die Rücklaufsperre wird ein Zurückbewegen der Druckprodukte von der Sperre weg verhindert. Der Bremseffekt wird nur bei einem möglichen Rückprall wirksam, denn beim Vorlaufen der Druckprodukte gegen die Sperre dreht die Druckrolle frei mit. Außerdem wird durch die Druckrolle der Schlupf auf Bandförderern reduziert, wenn nach Freigabe durch die Sperre die Druckprodukte wieder beschleunigt werden. Vorzugsweise ist die Rücklaufsperre von einem Freilauf gebildet.This object is achieved by at least one arranged in the transport direction behind the lock, a backstop against the transport direction having pressure roller. The backstop prevents backward movement of printed products away from the barrier. The braking effect is effective only in case of a possible rebound, because when the print products run against the barrier, the pressure roller rotates freely. In addition, the pressure roll reduces the slippage on belt conveyors when, once released by the barrier, the printed products are accelerated again. Preferably, the backstop is formed by a freewheel.

Die Kontaktfläche der Druckrolle und damit die übertragbare Rückhaltekraft kann durch eine vorzugsweise elastische Mantelfläche vergrößert werden, welche außerdem noch Dickenschwankungen kompensieren kann. Vorteilhaft für eine hohe Rückhaltekraft ist auch eine griffige Mantelfläche. Es können unterschiedlich dicke Produkt- bzw. Stapeldicken verarbeitet werden, wenn die Druckrolle auf Produkt- und Stapeldicke einstellbar ist. Mit einer angefederten Druckrolle können Dickenschwankungen ausgeglichen werden und außerdem eine definierte Druckkraft aufgebracht werden.The contact surface of the pressure roller and thus the transferable retention force can be increased by a preferably elastic lateral surface, which also can compensate for thickness variations. An advantage for a high retention force is also a grippy lateral surface. It can be processed with different thickness product or stack thicknesses when the pressure roller on product and stack thickness is adjustable. With a spring-loaded pressure roller thickness variations can be compensated and also a defined pressure force can be applied.

Um zu vermeiden, dass beim Vorlaufen des Druckprodukts bzw. -stapels deren vorlaufende Kante gegen eine evtl. zu tief eingestellte Druckrolle läuft und/oder beim taktgemäßen Weiterfördern nach Sperrenfreigabe die Druckrolle an der nachlaufenden Kante abläuft, ist in einer Ausbildungsform vorgesehen, dass die wenigstens eine Druckrolle durch Schwenken oder Verschieben gegen die Druckprodukte und zurück steuerbar ist. Insbesondere bei weichen Buchblocks und Büchern sowie bei Stapeln ist es vorteilhaft, dass die wenigstens eine Druckrolle auf eine Vorder- oder Rückseite der Druckprodukte wirkt. Durch die von der Druckkraft erzeugte Reibkraft wird insbesondere ein Zurückspringen der innen liegenden Blattlagen verhindert.In order to avoid that the leading edge runs against a possibly too deep set pressure roller when advancing the printed product or stack and / or expires the clockwise forwarding after locking release the pressure roller on the trailing edge, is provided in an embodiment that at least a pressure roller by pivoting or moving against the printed products and back is controllable. Particularly in the case of soft book blocks and books as well as in stacks, it is advantageous that the at least one pressure roller acts on a front or back side of the printed products. By the frictional force generated by the pressure force in particular a spring back of the inner sheet layers is prevented.

Für eine möglichst schlupffreie Beschleunigung der Druckprodukte nach Sperrenfreigabe ist der wenigstens einen Druckrolle gegenüberliegend eine taktgemäß angetriebene Beschleunigungsrolle zugeordnet. Die Weiterförderung kann auch dadurch beschleunigt werden, dass die wenigstens eine Druckrolle taktgemäß drehangetrieben ist.For as slip-free as possible acceleration of the printed products after lock release of the at least one pressure roller opposite a clock driven driven acceleration roller is assigned. The further promotion can also be accelerated by the fact that the at least one pressure roller is rotationally driven in line with the clock.

Die in Fig. 1 dargestellte Zuführeinrichtung 1 besteht aus einem ersten, kontinuierlich mit der Fördergeschwindigkeit V1 angetriebenen Bandförderer 3 als Zuführförderer für flachliegend und aufeinander folgend in Längsrichtung zugeführte Broschuren 2 und einem zweiten, mit der Fördergeschwindigkeit V2 schneller laufenden Bandförderer 4, als Weiterförderer von einer Sperre 5 taktweise freigegebener Broschuren 2. Die Sperre 5 ist zwischen den beiden Bandförderern 3, 4 angeordnet und gibt die jeweils vorderste Broschur 2 im Takt einer nicht weiter gezeigten Weiterverarbeitungsmaschine frei, sodass die Broschuren 2 auf dem Bandförderer 4 einen gleichen gegenseitigen Taktabstand L0 aufweisen. Der Bandförderer 4 kann kontinuierlich oder intermittierend angetrieben sein.In the Fig. 1 shown supply conveyor 1 consists of a first, continuously driven with the conveying speed V 1 belt conveyor 3 as a feed conveyor for lying flat and consecutively fed in the longitudinal direction brochures 2 and a second, with the conveyor speed V 2 faster running belt conveyor 4, as a conveyor from a lock 5 intermittently 2. The lock 5 is arranged between the two belt conveyors 3, 4 and releases the respective leading booklet 2 in time with a further processing machine, not shown further, so that the brochures 2 on the belt conveyor 4 have the same mutual pitch L 0 . The belt conveyor 4 can be driven continuously or intermittently.

Erfindungsgemäß ist hinter der Sperre 5 (in Transportrichtung gesehen) eine Druckrolle 6 mit einem Freilauf als Rücklaufsperre vorgesehen. Die Druckrolle 6 befindet sich an einem von einem Pneumatikzylinder 8 betätigten Hebel 7, wobei die Druckrolle 6 in einem bestimmten Abstand zur vor- bzw. nachlaufende Kante der Broschur 2 auf deren Oberseite mit einer definierten, ggf. einstellbaren Druckkraft aufgesetzt und wieder abgehoben wird. Die Druckrolle 6 ist mit einer griffigen Oberfläche versehen und dreht während der Vorbewegung der Broschur 2 frei mit, während ihre Rücklaufsperre ein Zurückbewegen der Broschur 2 von der Sperre 5 unterbindet. Insbesondere solche Broschuren 2, die aufgrund hoher Zuführgeschwindigkeit V1 und/oder hoher Masse mit entsprechend hoher Bewegungsenergie gegen die Sperre 5 bewegt werden, werden von der erfindungsgemäßen Druckrolle 6 an der Sperre 5 gehalten. Ein Zurückprallen wird verhindert. Nach dem Öffnen der Sperre 5 kann die Druckrolle 6 über eine bestimmte Wegstrecke synchron zum Bandförderer 4 drehangetrieben sein, zur nahezu schlupffreien Beschleunigung der Broschur 2 auf dessen Fördergeschwindigkeit V2 .According to the invention, a pressure roller 6 with a freewheel is provided behind the barrier 5 (seen in the transport direction) as a backstop. The pressure roller 6 is located on a operated by a pneumatic cylinder 8 lever 7, wherein the pressure roller 6 is placed at a certain distance from the leading or trailing edge of the brochure 2 on its upper side with a defined, possibly adjustable pressure force and lifted again. The pressure roller 6 is provided with a grippy surface and rotates freely during the forward movement of the brochure 2, while their backstop a move back the brochure 2 of the lock 5 prevents. In particular, such brochures 2, which are moved due to high feed rate V 1 and / or high mass with correspondingly high kinetic energy against the lock 5 are held by the pressure roller 6 of the invention to the lock 5. A rebound is prevented. After opening the lock 5, the pressure roller 6 may be rotationally driven over a certain distance in synchrony with the belt conveyor 4, for almost slip-free acceleration of the brochure 2 on the conveying speed V 2nd

Bei der in Fig. 2 dargestellten, gebundene Buchblocks 12 flachliegend mit dem Vorderschnitt 12 a voran zuführenden Zuführeinrichtung 11 ist die Sperre 5 vor der Umlenkrolle 4a des Bandförderers 4 angeordnet und die erfindungsgemäße Druckrolle 6 ist dieser Umlenkrolle 4 a im Wesentlichen gegenüberliegend angeordnet, sodass sie zusätzlich zu ihrer Rücklaufsperrenfunktion als Gegendruckrolle zur Beschleunigung des von der Sperre 5 taktgemäß freigegebenen Buchblocks 12 fungiert. Die Druckrolle 6 befindet sich an einem mittels einer Druckfeder 14 gegen die Buchblocks 2 vorgespannten, an einem Halter 15 drehgelagerten Hebel 13. An dem nach der Buchblockdicke höheneinstellbaren Halter 15 befindet sich noch eine Führungsschiene 16, die die Buchblocks 12 unter die Druckrolle 6 leitet.At the in Fig. 2 shown, bound book block 12 lying flat with the front section 12 a leading feeder 11, the lock 5 is disposed in front of the deflection roller 4a of the belt conveyor 4 and the pressure roller 6 according to the invention this deflection roller 4 a arranged substantially opposite, so that they in addition to their backstop function as a counter-pressure roller to accelerate the clock block 12 released in time according to the lock 5. The pressure roller 6 is located on a biased by a compression spring 14 against the book block 2, rotatably mounted on a holder lever 13 at the height adjustable by the book block holder 15 is still a guide rail 16 which guides the book block 12 under the pressure roller 6.

Mit der in Fig. 3 dargestellten Zuführeinrichtung 21 werden aus Falzbogen lose zusammengetragene Buchblocks 22 in einem aus seitlichen Führungen 24 a und einem Kanalboden 24 b gebildeten Förderkanal von Mitnehmern 23 a eines Zuführförderers 23 zu einer Übergabestelle 29 stehend transportiert. Die Mitnehmer 23 a befinden sich an einer kontinuierlich umlaufenden Förderkette 23 b und tauchen in einer Lücke des Kanalbodens 24 b hinter dem in die Übergabestelle 29 vorgeschobenen Buchblock 22 nach unten ab.With the in Fig. 3 shown feeder 21 are transported from folded sheets loosely assembled book block 22 in a from lateral guides 24 a and a channel bottom 24 b formed conveying channel of carriers 23 a of a feed conveyor 23 to a transfer point 29 standing transported. The drivers 23 a are located on a continuously rotating conveyor chain 23 b and dive in a gap of the channel bottom 24 b behind the advanced into the transfer point 29 book block 22 down.

Die Übergabestelle 29 weist vorne eine nach der Buchblockhöhe in Förderrichtung verstellbare Sperre 25 auf, gegen die die Buchblocks 22 von den Mitnehmern 23 a vorgeschoben und ausgerichtet werden. Mittels eines vor und zurück bewegten Klemmgreifers 28 werden die Buchblocks 22 aus der Übergabestelle 29 in eine nicht weiter gezeigte Arbeitsstation einer Weiterverarbeitungsmaschine überführt. Dabei wird der Förderpfad der Buchblocks 22 durch taktgemäßes Ausfahren der Sperre 25 freigegeben.The transfer point 29 has the front of an adjustable after the book block height in the conveying direction lock 25, against which the book blocks 22 are advanced and aligned by the drivers 23 a. By means of a back and forth moving clamping gripper 28, the book blocks 22 are transferred from the transfer point 29 in a workstation not further shown a further processing machine. In this case, the conveying path of the book block 22 is released by clockwise extension of the lock 25.

Damit die Buchblocks 22 nach dem Abtauchen der Mitnehmer 23 a nicht von der Sperre 25 zurückprallen und dabei ihre Ausrichtung verlieren, sind von beiden Seiten auf die Buchblocks 22 wirkende Druckrollen 26 mit Rücklaufsperre vorgesehen. Die Druckrollen 26 sind in Haltern 27 gelagert, die an den auf Buchblockdicke einstellbaren Führungen 24 a angeordnet sind. Sie weisen eine elastische Oberfläche 26 a auf und können dadurch nicht nur Dickenschwankungen der Buchblocks 22 ausgleichen sondern bieten eine entsprechend vergrößerte Kontaktfläche dar, zur Übertragung einer entsprechend hohen Rückhaltekraft.Thus, the book blocks 22 after the immersion of the driver 23 a does not bounce back from the lock 25 and thereby lose their alignment, acting on both sides of the book blocks 22 pressure rollers 26 are provided with backstop. The pressure rollers 26 are mounted in holders 27, which are adjustable to the book block thickness guides 24 a are arranged. They have an elastic surface 26 a and can thereby not only compensate for variations in thickness of the book block 22 but also provide a correspondingly enlarged contact surface for transmitting a correspondingly high retention force.
