Description

Die Erfindung betrifft eine Fördereinrichtung zur Beschickung einer Verarbeitungsvorrichtung mit Druckprodukten, mit der die Druckprodukte auf einem Förderweg durch einen ersten Förderer von einem Stapel, in welchem die Druckprodukte stehend angeordnet sind, an einen eine höhere Umlaufgeschwindigkeit als der erste Förderer aufweisenden zweiten Förderer zur Bildung einer Schuppenformation nach oben versetzt transportiert werden, wobei in einem durch das Förderende des ersten und dem Förderbeginn des zweiten Förderers gebildeten Übergabebereich eine auf die Druckprodukte einwirkende, aus wenigstens einem umlaufenden Zugmittel gebildete Niederhaltevorrichtung angeordnet ist.The invention relates to a conveyor for feeding a processing device with printed products, with which the printed products on a conveying path through a first conveyor from a stack, in which the printed products are arranged standing, to a higher circulating speed than the first conveyor having second conveyor to form a Scales formation are transported offset upwards, wherein in a formed by the conveying end of the first and the start of delivery of the second conveyor transfer area acting on the printed products, formed from at least one circulating pulling means hold-down device is arranged.

Vorrichtungen der eingangs genannten Art werden zur Beschickung von Anlegermagazinen an Zusammentragmaschinen, Sammelheftern und Einsteckmaschinen mit Druckprodukten in Betrieben der Druckweiterverarbeitung eingesetzt. Unter Druckprodukten sind dabei Produkte wie Druckbogen, Karten, CD/DVD-ROM, flächige Warenmuster usw. zu verstehen, deren Abmessungen in einem weiten Formatbereich variieren können.
Die Fördereinrichtung wird dazu mit den zu verarbeitenden Druckprodukten beladen. Je nach der Art der Anlieferung der Druckprodukte erfolgt die Beladung beispielsweise von Hand oder mittels Hebezeugen. Anschliessend stehen die Druckprodukte in der Form eines liegenden Stapels auf einer ihrer Seitenkanten auf einem etwa horizontal verlaufenden ersten Förderer, der die Druckprodukte bedarfsgeregelt einem nachgeschalteten zweiten Förderer zuführt. Dieser zweite Förderer hat die Aufgabe, die stapelförmige Formation der Druckprodukte auf dem ersten Förderer in eine schuppenförmige Formation umzusetzen und die Druckprodukte anschliessend in dieser bevorzugten Formation einem Magazin einer Verarbeitungsmaschine zuzuführen. Zu diesem Zweck bildet der erste Förderer mit dem zweiten Förderer einen stumpfen Winkel und die Geschwindigkeit des zweiten Förderers ist wesentlich höher als die des ersten Förderers. Die Verschuppungsfunktion basiert auf dem Reibungsprinzip. Das Ziel ist die Bildung einer möglichst gleichmässigen Schuppung, um die besten Voraussetzungen für eine optimale Funktion des Anlegers der Verarbeitungsmaschine zu erreichen. Die Gleichmässigkeit soll so sein, dass aneinander anliegende Druckbogen mindestens gegeneinander verschoben werden und in der Schuppenformation keine Lücken entstehen. Zudem dürfen die Druckprodukte während der Schuppenbildung nicht schief in Bezug zur Förderrichtung gezogen werden. Die Bildung der Schuppe aus dem liegenden Stapel bildet somit die zentrale Funktion einer Fördereinrichtung. Dazu sind zu den bereits erwähnten, weitere Organe und Funktionen erforderlich, die die Wirkung der beiden Förderer unterstützen. Im Endbereich des ersten Förderers können beidseits des Stapels angetriebene Förderorgane in Form von Rollen, Bändern oder Ketten vorgesehen sein, die die Druckprodukte quer zu ihrer Förderrichtung leicht stauchen resp. vorseparieren. Weiterhin ist bei Fördereinrichtungen nach dem Stand der Technik eine Niederhaltevorrichtung aus mehreren umlaufend angetriebenen Zugmitteln vorgesehen, die sich über den Endbereich des ersten Förderers resp. bis an den geneigten vorderen Abschnitt des zweiten Förderers erstreckt und die Druckprodukte an deren oberen Seitenkanten erfassend gegen das untere Förderelement des ersten Förderers und den vorderen Abschnitt des zweiten Förderers presst. Da die durch den ersten Förderer gebildete Förderebene fix definiert ist, muss zwingend die Niederhaltevorrichtung an die Höhe der Druckprodukte und ebenfalls an die Dicke des erzeugten Schuppenstromes angepasst werden. Daraus resultiert bei einer Niederhaltevorrichtung nach dem Stand der Technik eine Verstellung der Position der Niederhaltevorrichtung in zwei Achsen. Diese Einstellung ist zeitintensiv und kritisch, weil damit wesentlich die Schuppenbildung beeinflusst wird. Zudem müssen die Einstellungen im Betrieb, zum Beispiel wenn die Schuppendicke infolge Änderung des Geschwindigkeitsverhältnisses zwischen erstem und zweitem Förderer verstellt wird, den sich ändernden Umständen angepasst werden.Devices of the type mentioned are used for feeding investors magazines on gathering machines, saddle stitchers and insertion machines with printed products in companies of print finishing. Among printed products are products such as printed sheets, cards, CD / DVD-ROM, flat Patterns, etc. whose dimensions may vary within a wide format range.
For this purpose, the conveyor is loaded with the printed products to be processed. Depending on the type of delivery of the printed products, the loading is done for example by hand or by means of lifting equipment. Subsequently, the printed products are in the form of a horizontal stack on one of its side edges on an approximately horizontally extending first conveyor, which feeds the printed products demand-controlled a downstream second conveyor. This second conveyor has the task of converting the stack-shaped formation of the printed products on the first conveyor into a scale-like formation and then feeding the printed products in this preferred formation to a magazine of a processing machine. For this purpose, the first conveyor forms an obtuse angle with the second conveyor and the speed of the second conveyor is substantially higher than that of the first conveyor. The scaly function is based on the friction principle. The aim is to create as even as possible scaling in order to achieve the best conditions for optimal functioning of the feeder of the processing machine. The uniformity should be such that adjoining printed sheets are at least shifted against each other and no gaps are formed in the imbricated formation. In addition, the printed products must not be drawn obliquely with respect to the conveying direction during flaking. The formation of the scale from the horizontal stack thus forms the central function of a conveyor. To this end, other organs and functions are required, which support the effect of the two promoters. In the end region of the first conveyor driven conveying elements can be on both sides of the stack be provided in the form of rolls, belts or chains that easily compress the printed products transversely to their conveying direction resp. vorseparieren. Furthermore, in conveyors according to the prior art, a hold-down device of a plurality of circumferentially driven traction means is provided, which respectively over the end region of the first conveyor resp. extends to the inclined front portion of the second conveyor and presses the printed products at the upper side edges thereof in detection against the lower conveyor element of the first conveyor and the front section of the second conveyor. Since the conveying plane formed by the first conveyor is fixedly defined, the hold-down device must be adapted to the height of the printed products and also to the thickness of the generated scale flow. This results in a hold-down device according to the prior art, an adjustment of the position of the hold-down device in two axes. This setting is time-consuming and critical because it significantly affects dandruff. In addition, the settings in operation, for example, when the shoe thickness is adjusted as a result of changing the speed ratio between the first and second conveyor, must be adapted to the changing circumstances.

Aufgabe der vorliegenden Erfindung ist es, eine Niederhaltevorrichtung so auszugestalten, dass keine Verstellung bei sich ändernder Höhe der Druckprodukte und der Dicke des Schuppenstromes mehr notwendig ist, sodass sich diese den veränderten Betriebsbedingungen automatisch anpassen kann.Object of the present invention is to design a hold-down device so that no adjustment with changing height of the printed products and the thickness of the scale flow is more necessary, so that they can automatically adapt to the changed operating conditions.

Diese Aufgabe wird gemäss der Erfindung bei einer Fördereinrichtung der genanten Art dadurch gelöst, dass das Zugmittel wenigstens im Übergabebereich ein auf den Druckprodukten frei aufliegendes Arbeitstrum aufweist.This object is achieved according to the invention in a conveyor of the type mentioned in that the traction means has at least in the transfer area on the printed products freely resting Arbeitsstrum.

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

The invention will be explained below with reference to the drawing, to which reference is made with respect to all details not mentioned in the description, using an exemplary embodiment. In the drawing show:

Die Fig. 1 und Fig. 2 zeigen eine Fördereinrichtung 1, die einen ersten Förderer 2 und einen zweiten Förderer 3 aufweist, sowie eine Verarbeitungsvorrichtung 6, deren Magazin 7 durch die Fördereinrichtung 1 mit Druckprodukten 5 beschickt wird. Die Druckprodukte 5 werden üblicherweise in Form von umreiften Stangen 10 (Fig. 3) angeliefert und damit der erste Förderer 2 beladen. Eine Stange 10 entspricht einem langen Stapel aus Druckprodukten 5, der an beiden Enden mit einem Endbrett 12 abgeschlossen und mit einer Umreifung 11 versehen ist. Es ist jedoch auch denkbar die Druckprodukte 5 als lose Stapel von Hand oder mittels Handlingsystemen zu beladen.1 and 2 show a conveyor 1, which has a first conveyor 2 and a second conveyor 3, and a processing device 6, whose magazine 7 is fed by the conveyor 1 with printed products 5. The printed products 5 are usually supplied in the form of strapped rods 10 (FIG. 3) and thus load the first conveyor 2. A rod 10 corresponds to a long stack of printed products 5, which is completed at both ends with a end board 12 and provided with a strapping 11. However, it is also conceivable to load the printed products 5 as a loose stack by hand or by means of handling systems.

Nach der Beladung stehen die Druckprodukte 5 mit einer ihrer Seitenkanten 13 auf einem ersten umlaufend angetriebenen Fördermittel 8 des ersten Förderers 2. Seitliche Führungselemente 21,22 erleichtern das Absetzen der Druckprodukte 5 in der richtigen seitlichen Position und verhindern ein seitliches Wegrutschen während der Förderung in Richtung v. Im Endbereich des ersten Förderers 2 werden die Druckprodukte 5 seitlich durch angetriebene Förderorgane 14,15 leicht eingespannt und mit in etwa der Geschwindigkeit des Fördermittels 8 in der Richtung v weiter transportiert. Durch diese Art des Transports werden die Druckprodukte 5 bogenförmig deformiert und eine allenfalls vorhandene Haftung zwischen den einzelnen Druckprodukten 5 wird abgebaut. Am Ende des ersten Förderers 2 liegen die Druckprodukte 5 mit ihrer flächigen Seite mindestens im Bereich ihrer Mittelachse 35 am unteren Förderteil 24 des zweiten Förderers 3, beispielsweise einem Bandförderer, an. Die Förderrichtung v des ersten Förderers 2 bildet mit der Förderrichtung x des zweiten Förderers 3 einen stumpfen Winkel α. Im unteren Bereich 26 erfolgt ein Druckkraftaufbau durch die Förderwirkung des Förderelements 25 des ersten Förderers 2, das die Druckprodukte 5 gegen das untere Förderteil 24 vorschiebt. Im oberen Bereich 27 werden die Druckprodukte 5 durch das eine Niederhaltevorrichtung 16 bildende Zugmittel 9, beispielsweise eine Kette, gegen das untere Förderteil 24 gedrückt. Sobald die Reibkräfte zwischen dem vordersten, noch auf dem Förderelement 25 stehenden Druckprodukt 5 und dem unteren Förderteil 24 und den sich bereits in der Richtung x bewegenden Druckprodukten 5 grösser werden als die Reibkraft zwischen dem vordersten und dem zweitvordersten Druckprodukt 5, beginnt sich das vorderste Druckprodukt 5 ebenfalls in Richtung x zu bewegen. Die Förderwirkungen der Niederhaltevorrichtung 16 und des unteren Förderteils 24 auf die Druckprodukte 5 basieren ausschliesslich auf Reibkräften. Die für den Aufbau dieser Reibkräfte benötigten Normalkräfte werden wesentlich durch die Niederhaltevorrichtung 16 aufgebracht. Das Zugmittel 9 der Niederhaltevorrichtung 16 wird über ein auf einer Welle 23 befestigtes Antriebsrad 30 in der Richtung y angetrieben. Die Geschwindigkeit der Niederhaltevorrichtung 16 ist mindestens so hoch wie die Geschwindigkeit des unteren Förderteils 24. Die Welle 23 ist im Grundbau 4 drehbar gelagert und durch einen nicht dargestellten Antrieb angetrieben. Das Hilfstrum 33 des Zugmittels 9 gleitet durch sein Eigengewicht auf der Zugmittelführung 28 in die Richtung des ersten Förderers 2 und liegt dort durch sein Eigengewicht auf der oberen Seitenkante 13 der Druckprodukte 5 auf. An der Zugmittelführung 28 ist mindestens ein Gleitschuh 18 befestigt, der permanent auf den oberen Seitenkanten 13 der Druckprodukte 5 im ersten Förderer 2 aufliegt und dadurch die Lage der Zugmittelführung 28 relativ zu den oberen Seitenkanten 13 der Druckprodukte 5 konstant hält. Es ist denkbar, anstelle des Gleitschuhs 18 ein frei drehbares Rad vorzusehen, das sich auf den oberen Seitenkanten 13 der Druckprodukte 5 abwälzt und an der Zugmittelführung 28 gelagert ist. Die Zugmittelführung 28 ist frei gelagert. Eine bevorzugte Ausbildungsform der Lagerung ergibt sich, wenn die Zugmittelführung 28 auf der Welle 23 gelagert wird und somit um die Achse 29 der Welle 23 schwenken kann. Es sind jedoch auch andere Positionen der Schwenkachse 29 denkbar. Bei der Verarbeitung von Druckprodukten 5 mit speziellen Eigenschaften kann es sinnvoll sein, die Auflagekraft F des Gleitschuhs 18 zu verändern. Zu diesem Zweck ist ein Gewicht 19 vorgesehen, das sich in der Richtung w auf einem fest mit der Zugmittelführung 28 verbundnen Hebel 17 verschieben lässt und sich in der gewählten Position mit einer Arretierung 20, beispielsweise einer Feststellschraube, sichern lässt. Je nachdem ob sich der Schwerpunkt des Gewichts 19 links oder rechts über der Achse 29 befindet, wird die Auflagekraft F des Gleitschuhs 18 erhöht oder vermindert. Anstelle des Gewichts liesse sich die gleiche Wirkung beispielsweise auch durch den Einsatz aller Arten von Federelementen, Pneumatikzylindern oder elektrischen Antrieben erreichen. Die erfindungsgemässe Lösung zeichnet sich durch eine einfache Bedienbarkeit und eine Selbsteinstellung der Niederhaltevorrichtung auf die formatabhängige Lage der oberen Seitenkanten der Druckprodukte 5 und der Dicke des entstehenden Schuppenstromes aus. Das biegeweiche Zugmittels kann sich an eine beliebige Formation der oberen Seitenkanten 13 der Druckprodukte 5 im Übergabebereich 31 anschmiegen und es ergibt sich eine vorteilhafte Verteilung der Auflagekräfte des Zugmittels 9 auf den Druckprodukten 5.After loading, the printed products 5 are at one of their side edges 13 on a first circulating driven conveyor 8 of the first conveyor 2. Lateral guide elements 21,22 facilitate settling of the printed products 5 in the correct lateral position and prevent lateral slippage during the promotion in the direction v. In the end region of the first conveyor 2, the printed products 5 are slightly clamped laterally by driven conveyor members 14,15 and transported at approximately the speed of the conveyor 8 in the direction v on. By this type of transport, the printed products 5 are arcuately deformed and any existing adhesion between the individual printed products 5 is degraded. At the end of the first conveyor 2, the printed products 5 lie with their flat side at least in the region of their central axis 35 on the lower conveyor part 24 of the second conveyor 3, for example a belt conveyor. The conveying direction v of the first conveyor 2 forms an obtuse angle α with the conveying direction x of the second conveyor 3. In the lower region 26, a pressure force build-up is effected by the conveying action of the conveying element 25 of the first conveyor 2, which advances the printed products 5 against the lower conveying part 24. In the upper region 27, the printed products 5 are pressed against the lower conveying part 24 by the traction means 9, for example a chain, forming a holding-down device 16. As soon as the frictional forces between the foremost printing product 5 still standing on the conveying element 25 and the lower conveying part 24 and the printed products 5 already moving in the direction x become greater than the frictional force between the foremost and the second leading printed product 5, the foremost printed product begins 5 also to move in the direction of x. The conveying effects of the hold-down device 16 and the lower conveyor part 24 on the printed products 5 are based exclusively on frictional forces. The normal forces required for the construction of these frictional forces are substantially applied by the hold-down device 16. The traction means 9 of the hold-down device 16 is driven via a mounted on a shaft 23 drive wheel 30 in the direction y. The speed of the hold-down device 16 is at least as high as the speed of the lower conveyor part 24. The shaft 23 is rotatably mounted in the basic structure 4 and driven by a drive, not shown. The auxiliary strand 33 of the traction means 9 slides by its own weight on the traction means guide 28 in the direction of the first conveyor 2 and is there by its own weight on the upper side edge 13 of the printed products 5 on. At least one sliding shoe 18, which rests permanently on the upper side edges 13 of the printed products 5 in the first conveyor 2 and thereby keeps the position of the traction mechanism guide 28 constant relative to the upper side edges 13 of the printed products 5, is attached to the traction mechanism guide 28. It is conceivable to provide, instead of the sliding shoe 18, a freely rotatable wheel which rolls on the upper side edges 13 of the printed products 5 and is mounted on the traction mechanism guide 28. The Zugmittelführung 28 is stored freely. A preferred embodiment of the bearing results when the traction means guide 28 is mounted on the shaft 23 and thus can pivot about the axis 29 of the shaft 23. However, other positions of the pivot axis 29 are conceivable. In the processing of printed products 5 with special properties, it may be useful to change the contact force F of the shoe 18. For this purpose, a weight 19 is provided, which move in the direction w on a fixed to the Zugmittelführung 28 lever 17 leaves and can be secured in the selected position with a lock 20, such as a locking screw. Depending on whether the focus of the weight 19 is left or right above the axis 29, the contact force F of the shoe 18 is increased or decreased. Instead of the weight, the same effect could be achieved, for example, by the use of all types of spring elements, pneumatic cylinders or electric drives. The inventive solution is characterized by a simple operation and self-adjustment of the hold-down device on the format-dependent position of the upper side edges of the printed products 5 and the thickness of the resulting scale flow. The flexurally soft traction device can conform to any desired formation of the upper side edges 13 of the printed products 5 in the transfer region 31 and results in an advantageous distribution of the contact forces of the traction device 9 on the printed products 5.
