Description

Die Erfindung betrifft eine Vorrichtung zur Beschickung einer Verarbeitungsvorrichtung mit Druckprodukten, bestehend aus einer Fördervorrichtung, die in Förderrichtung betrachtet einen ersten Zuführabschnitt für die stehend hintereinander gestapelten Druckprodukte bildenden ersten Förderer und einen zweiten Förderers zur Bildung eines geschuppten, nach oben gerichteten Schuppenstromes aufweist, wobei zwischen dem ersten und dem zweiten Förderer eine Trennung der Druckprodukte an dem vorderen Ende von dem Stapel in einen Teilstapel von in Förderrichtung geneigten Druckprodukten vorgesehen ist.The invention relates to a device for feeding a processing device with printed products, consisting of a conveying device, as viewed in the conveying direction, a first feed section for standing one behind the other stacked printed products forming first conveyor and a second conveyor to form a shingled, upwardly directed scale flow, wherein between the first and the second conveyor, a separation of the printed products at the front end of the stack is provided in a partial stack of printed products inclined in the conveying direction.

Die eingangs genannte Vorrichtung wird in Betrieben der Druckweiterverarbeitung zur Beschickung von Anlegermagazinen mit Druckprodukten an zusammentragmaschinen, Sammelhefter und Einsteckmaschinen angewendet. Unter Druckprodukten sind beispielsweise Druckbogen, Karten, CD/DVD-ROM, flächige Warenmuster usw. zu verstehen, deren Abmessungen in einem weiten Bereich variieren können.
Eine Fördervorrichtung nach dem Stand der Technik zur Durchführung des Verfahrens ist in der EP 1 714 925 A1 offenbart. Die Fördervorrichtung wird durch einen etwa horizontal ausgerichteten ersten Förderer und einen im Übergabebereich im Wesentlichen quer zum ersten Förderer angeordneten zweiten Förderer gebildet. Die in das Anlegermagazin zu transportierenden Druckprodukte werden von Hand oder mittels Hebezeugen auf dem ersten Förderer der Fördervorrichtung zu einem liegenden Stapel aufgeschichtet, wobei die Druckprodukte an einer ihrer Seitenkanten auf einem Fördermittel des ersten Förderers aufliegen. Durch den ersten Förderer werden die Druckprodukte bedarfsgeregelt dem nachgeschalteten zweiten Förderer zugeführt, der die stapelförmige Formation der Druckprodukte des ersten Förderers in eine schuppenförmige Formation umsetzt und die Druckprodukte in dieser bevorzugten Formation in ein Magazin einer Verarbeitungsmaschine überführt. Dazu bildet der erste Förderer mit dem zweiten Förderer im Übergabebereich einen stumpfen Winkel und die Geschwindigkeit des zweiten Förderers ist wesentlich höher als die des ersten Förderers. Die Druckprodukte werden durch den ersten Förderer, der sich bis unmittelbar an den zweiten Förderer erstreckt, form- oder reibschlüssig gegen den zweiten Förderer vorgeschoben und durch diesen reibschlussig weggefördert. Die Bildung einer Schuppe aus dem liegenden Stapel gehört zur zentralen Funktion einer solchen Fördereinrichtung.The device mentioned above is used in companies of print finishing for feeding investor magazines with printed products to gathering machines, saddle stitchers and insertion machines. For example, under printed products Sheets, cards, CD / DVD-ROM, flat product samples, etc. whose dimensions can vary over a wide range.
A conveyor device according to the prior art for carrying out the method is in the EP 1 714 925 A1 disclosed. The conveyor device is formed by an approximately horizontally oriented first conveyor and a second conveyor arranged in the transfer area essentially transversely to the first conveyor. The printed products to be transported to the feeder magazine are stacked by hand or by means of hoists on the first conveyor of the conveyor to a horizontal stack, wherein the printed products rest on one of its side edges on a conveyor of the first conveyor. By the first conveyor, the printed products are demand-controlled fed to the downstream second conveyor, which converts the stacked formation of the printed products of the first conveyor in a scale-like formation and transferred the printed products in this preferred formation in a magazine of a processing machine. For this purpose, the first conveyor with the second conveyor in the transfer area forms an obtuse angle and the speed of the second conveyor is substantially higher than that of the first conveyor. The printed products are advanced by the first conveyor, which extends directly to the second conveyor, positively or frictionally against the second conveyor and conveyed away by this reibschlussig. The formation of a scale from the horizontal stack belongs to the central function of such a conveyor.

Die vorveröffentlichte WO 03/068644 A1 betrifft eine Vorrichtung zur Vereinzelung von in einem kompakten Stapel 1 vorkommenden, stehenden Druckprodukten. Ein erstes Förderband trägt den Stapel der Druckprodukte, ein anschliessendes zweites Förderband schliesst förderwirksam an das erste Förderband an. Auf beiden Seiten des Stapels befinden sich den Förderweg verengende Seitenführungen.The pre-published WO 03/068644 A1 relates to a device for singulating occurring in a compact stack 1, standing printed products. A first conveyor belt carries the stack of printed products, a subsequent second conveyor belt adjoins the first conveyor conveyor effectively. On both sides of the stack are the conveying path narrowing side guides.

Die EP 0125214 offenbart eine Fördervorrichtung zur kontinuierlichen Förderung von stehend gestapelten Druckprodukten und weist Seitenführungen auf. Im Endbereich der Seitenführungen verengt sich der Förderweg, sodass sich die Druckprodukte in Förderrichtung wölben und sich dadurch voneinander trennen, so dass sie in einer Schuppenformation weitertransportiert werden.The EP 0125214 discloses a conveyor for continuously conveying stacked printed products and has side guides. In the end region of the side guides, the conveying path narrows, so that the printed products bulge in the conveying direction and thereby separate from one another, so that they are transported onward in an imbricated formation.

Die US 3 598 399 betrifft einen Druckprodukteanleger, mit dem in Stangen stehend gestapelte Druckprodukte vereinzelt und einer Verarbeitungseinrichtung zugeführt werden. Die Stange liegt auf einem Bett und wird von einer hinten angreifenden Pressplatte gegen eine Vereinzelungsvorrichtung gestossen. Das Bett, auf dem die Stange liegt, ist abgestuft, so, dass die Druckprodukte in einem entspannten Bereich auf eine tiefere Ebene rutschen und sich voneinander trennen.The US 3,598,399 relates to a printed product feeder with which printed products stacked in bars are singulated and fed to a processor. The rod lies on a bed and is pushed against a separating device by a pressure plate engaging behind. The bed on which the bar is located is stepped, so that the printed products in a relaxed area to a lower level slip and separate.

Es ist die Aufgabe der vorliegenden Erfindung, den Druck resp. die Druckkräfte zwischen den Druckprodukten im verschuppungsbereich wesentlich zu reduzieren.It is the object of the present invention, the pressure resp. to significantly reduce the pressure forces between the printed products in the scum area.

Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass das auf dem ersten Zuführabschnitt in Förderrichtung vordere Ende des ersten Förderers durch eine Gleitauflage ausgebildet ist und dass eine im Bereich des in Förderrichtung vorderen Endes des ersten Förderers auf ein von dem Teilstapel getrennten Reststapel auf den freistehenden oberen Randbereich der Druckprodukte einwirkende Rückhaltevorrichtung und im Bereich der Gleitauflage eine auf die Unterseite des Teilstapels und/oder des Reststepels einwirkende, gegen die förderrichtung wirkende Vorrichtung angeordnet ist.This object is achieved according to the invention in that the front end of the first conveyor on the first feed section in the conveying direction is replaced by a sliding support is formed and that in the region of the front end in the conveying direction of the first conveyor acting on a separate stack of the partial stack on the free-standing upper edge region of the printed products acting restraint and in the region of the sliding support acting on the underside of the sub-stack and / or the rest of the plug, against the conveying direction acting device is arranged.

Die Fig. 1 und 2 zeigen eine Fördervorrichtung 1 zur Beschickung einer Verarbeitungsvorrichtung 15 mit Druckprodukten 2, die auf einem ersten flachen Zuführabschnitt 3 einer Zuführstrecke 4 stehend hintereinander gestapelt sind und auf einem anschliessenden zweiten Zuführabschnitt 5 in einem Schuppenstrom 6 angeordnet sind, wobei von dem auf dem ersten Zuführabschnitt 3 sich befindenden Stapel 7 an dem in Förderrichtung F1 vorderen Ende 8 ein Teilstapel 9 abgetrennt wird. Der erste Zuführabschnitt 3 umfasst einen ersten Förderer 16 und der zweite Zuführabschnitt 5 einen zweiten Förderer 17. In einem durch den Endbereich des ersten Förderers 16 und den Anfangsbereich des zweiten Förderers 17 gebildeten Übergabebereich 27 bilden die Förderrichtung F1 des ersten Förderers 16 und die Förderrichtung F2 des zweiten Förderers 17 einen stumpfen Winkel α. Im ersten Zuführabschnitt 3 sind die Druckprodukte 2 auf einer ihrer Seitenkanten stehend hintereinander in der Form eines liegenden Stapels 7 aneinandergereiht, aus dem im zweiten Zuführabschnitt 5 ein geschuppter, nach oben gerichteter Förderstrom 18 gebildet wird, der als Schuppenstrom 6 der Verarbeitungsvorrichtung 15, beispielsweise einem Magazin eines Anlegers, zugeführt wird. Der für die Förderung des Stapels 7 im ersten Zuführabschnitt 3 vorgesehene erste Förderer 16 ist in zwei Bereiche aufgeteilt. Im ersten Bereich ist ein Fördermittel 26, das beispielsweise durch mehrere nebeneinander angeordnete, umlaufende und angetriebene Zugmittel, wie Ketten oder Riemen gebildet wird, vorgesehen. Im anschliessenden zweiten Bereich resp. dem in Förderrichtung F1 vorderen Ende 8' ist der erste Förderer 16 durch eine Gleitauflage 21 ausgebildet, die wenigstens die Länge des Teilstapels 9 aufweist. Im Bereich des stromabwärts liegenden Endes des Fördermittels 26 ist auf beide Seiten des Stapels 7 verteilt eine aus zwei Teilen 28,29 gebildete sog. Brechvorrichtung vorgesehen, die eine seitliche Verengung bewirkt und die Druckprodukte 2 auf der Gleitauflage 21 staucht, so dass der Teilstapel 9 -wie Fig. 2 zeigt- durch die gewölbte Bogenform der Druckprodukte 2 gelockert wird. Durch die Verengung und das Stauchen erhalten die Druckprodukte 2 eine gebogene Form und werden gegenseitig leicht verschoben. Eine an dem vorderen Ende auf einen freistehenden Randbereich 20 des Reststapels 12 einwirkende Rückhaltevorrichtung 19 ist stromabwärts nach der Brechvorrichtung angeordnet und hält den Reststapel 12 zurück, sodass die Druckprodukte 2 gehindert sind in Förderrichtung F1 zu kippen.The Fig. 1 and 2 show a conveying device 1 for feeding a processing device 15 with printed products 2, which are stacked standing on a first flat feed section 3 of a feed line 4 and are arranged on a subsequent second feed section 5 in a scale flow 6, of which on the first feed section 3 itself located stack 7 at the front end 8 in the conveying direction F1 a partial stack 9 is separated. The first feed section 3 comprises a first conveyor 16 and the second feed section 5 comprises a second conveyor 17. In one through the end area of the first conveyor 16 and the starting area of the second conveyor 17 formed transfer area 27 form the conveying direction F1 of the first conveyor 16 and the conveying direction F2 of the second conveyor 17 at an obtuse angle α. In the first feed section 3, the printed products 2 are arranged one behind the other on one of their side edges in the form of a horizontal stack 7, from which in the second feed section 5 a scaly, upwardly directed flow 18 is formed, the shingled stream 6 of the processing device 15, for example a Magazine of an investor who is fed. The intended for the promotion of the stack 7 in the first feed section 3 first conveyor 16 is divided into two areas. In the first area is a conveyor 26, which is for example formed by a plurality of juxtaposed, rotating and driven traction means, such as chains or belts is provided. In the subsequent second area resp. the front end 8 'in the conveying direction F1, the first conveyor 16 is formed by a sliding support 21, which has at least the length of the partial stack 9. In the region of the downstream end of the conveying means 26, a so-called breaking device formed from two parts 28, 29 is provided on both sides of the stack 7, which causes a lateral narrowing and compresses the printed products 2 on the sliding support 21, so that the partial stack 9 -as Fig. 2 shows by the curved arc shape of the printed products 2 is loosened. Due to the narrowing and upsetting the printed products 2 get a curved shape and are slightly shifted each other. A retaining device 19 acting on a free-standing edge region 20 of the residual stack 12 at the front end is arranged downstream of the breaking device and retains the residual stack 12 so that the printed products 2 are prevented from tilting in the conveying direction F1.

Zudem trennt die Rückhaltevorrichtung 19 den Stapel 7 in einen Reststapel 12 mit senkrecht stehenden Druckprodukten 2 und einen Teilstapel 9 mit in Förderrichtung F1 geneigten Druckprodukten 2, wobei das obere Ende 10 des Teilstapels 9 gegenüber dem unteren Ende 11 des Teilstapels 9 vorausläuft. Es ist e-benfalls denkbar, die Rückhaltevorrichtung 19 seitlich des Stapels 7 anzuordnen, wobei wesentlich ist, dass sie auf den oberen Randbereich 24 des Reststapels 12 einwirkt, wie in der Fig. 5 dargestellt. Vorzugsweise wird die Rückhaltevorrichtung 19 als Hebel ausgebildet, der durch eine, von einer Feder 30 aufgebrachte Kraft gegen den Reststapel 12 gehalten wird und dessen eine Endlage durch einen Anschlag 31 begrenzt. Die im oberen Randbereich 24 durch die Rückhaltevorrichtung 19 frei gegebenen Druckprodukte 2 können mittels Blasdüsen 22 sanft an den Teilstapel 9 gefördert werden. Mit ihrer Unterseite 13 stehen der Teilstapel 9 und möglicherweise ein Teil des Reststapels 12 auf der Gleitauflage 21, die während der Förderung Reibkräfte gegen die Förderrichtung F1 an den Druckprodukten 2 erzeugt. Die Oberflächenbeschaffenheit der Gleitauflage 21 hat einen wesentlichen Einfluss auf die Reibkräfte gegenüber den Druckprodukten 2 und kann beispielsweise als Führung mit glatter bis rauer Oberfläche oder auch als Bürste ausgebildet sein. Es ist ebenfalls denkbar, die Gleitauflage 21 in Förderrichtung F1 in sich folgende Segmente mit unterschiedlichen Oberflächen und Reibwerten aufzuteilen. Der Teilstapel 9 wird durch den nachrückenden Reststapel 12 gleitend fortbewegt. Im Übergabebereich 27 ist nur noch der sich durch die Schiefstellung der Druckprodukte 2 im Teilstapel 9 ergebende Stapeldruck wirksam. Für eine zusätzliche Reduktion des Stapeldrucks im Übergabebereich 27 ist im Bereich der Gleitauflage 21 mindestens eine auf die Unterseite 13 des Teilstapels 9 oder des Reststapels 12 einwirkende, gegen die Förderrichtung F1 wirkende Vorrichtung 14, beispielsweise eine sich gegen die Förderrichtung F1 bewegende Bürstenwalze 23 vorgesehen, die den Teilstapel 9 und/oder den Reststapel 12 bremst, womit eine zusätzliche Verbesserung der Schuppenqualität erzielbar ist. Mittels im Übergabebereich 27 angeordneten zusätzlichen Blasdüsen 25, die gegen die Randbereiche der Druckprodukte 2 gerichtet sind, ist die Reibung zwischen den Druckprodukten 2 ebenfalls beeinflussbar.In addition, the retaining device 19 separates the stack 7 into a residual stack 12 with vertical printed products 2 and a partial stack 9 with printing products 2 inclined in the conveying direction F1, the upper end 10 of the partial stack 9 leading in front of the lower end 11 of the partial stack 9. It is e-benfalls conceivable to arrange the retaining device 19 side of the stack 7, wherein it is essential that it acts on the upper edge region 24 of the remainder of the stack 12, as in Fig. 5 shown. Preferably, the retaining device 19 is formed as a lever which is held by a, applied by a spring 30 force against the residual stack 12 and limits its one end position by a stop 31. The pressure products 2 released in the upper edge region 24 by the retaining device 19 can be conveyed gently to the partial stack 9 by means of blowing nozzles 22. With its underside 13, the partial stack 9 and possibly a part of the remaining stack 12 are on the sliding support 21, which generates frictional forces against the conveying direction F1 on the printed products 2 during the conveyance. The surface finish of the sliding support 21 has a significant influence on the frictional forces against the printed products 2 and may be formed, for example, as a guide with a smooth to rough surface or as a brush. It is also conceivable to divide the sliding support 21 in the conveying direction F1 into following segments with different surfaces and coefficients of friction. The partial stack 9 is moved by the advancing residual stack 12 slidably. In the transfer area 27, only the stacking pressure resulting from the misalignment of the printed products 2 in the partial stack 9 is effective. For an additional reduction of the stack pressure in the transfer region 27, at least one on the underside 13 of the sub-stack 9 or the Residual stack 12 acting, acting against the conveying direction F1 device 14, for example, provided a against the conveying direction F1 moving brush roller 23 which brakes the partial stack 9 and / or the remaining stack 12, whereby an additional improvement of the scale quality can be achieved. By means disposed in the transfer area 27 additional tuyeres 25 which are directed against the edge regions of the printed products 2, the friction between the printed products 2 is also influenced.
