Abstract

The printed products (2) are conveyed in suspended position crosswise to their main surfaces. Conveyors (13) or one conveyor (11) convey holders (1) along a conveyor stretch. A stacking surface (4) has an underneath foot (5) and protrudes into the flow of conveyed articles. The stacking surface has a top edge on a plane parallel with the main surfaces of the printed products. The holders are equidistant on the conveyor and are opened separately by pick-up pieces (11).

Description

Die Erfindung betrifft ein Verfahren gemäss dem Oberbegriff des ersten, unabhängigen Patentanspruchs. Das Verfahren dient zum Ausschleusen von Druckprodukten aus einem Förderstrom und zum Bilden von Stapeln aus den ausgeschleusten Druckprodukten. Ferner betrifft die Erfindung eine Vorrichtung zur Durchführung des Verfahrens.The invention relates to a method according to the preamble of the first, independent claim. The process is used to discharge Print products from a flow and to form stacks from the ejected printed products. The invention further relates to a device to carry out the procedure.

Druckprodukte werden während ihrer Verarbeitung, beispielsweise zwischen aufeinanderfolgenden Verarbeitungsstationen, meist in Form von Förderströmen transportiert. In solchen Förderströmen liegen die Druckprodukte beispielsweise auf einer Förderfläche hintereinander oder einander überlappend (Schuppenstrom) auf und werden im wesentlichen parallel zu ihren Hauptflächen gefördert oder die Druckprodukte werden einzeln von Haltemitteln beispielsweise hängend gehalten im wesentlichen quer zu ihren Hauptflächen gefördert. Print products are processed during their processing, for example between successive processing stations, mostly in the form of flow rates transported. The printed products, for example, are located in such flow rates on a conveyor surface one behind the other or overlapping each other (Scale flow) and are essentially parallel to their main surfaces conveyed or the printed products are individually by holding means for example, suspended substantially perpendicular to their major surfaces promoted.

Druckprodukte werden für verschiedene Verarbeitungen zu Stapeln gesammelt (Zwischenlagerung, Verpackung) und anschliessend in Stapelform (Stangen, Pakete usw.) weitergefördert und/oder weiter verarbeitet.Printed products are collected into stacks for various processing (Intermediate storage, packaging) and then in stack form (bars, Parcels etc.) conveyed and / or processed.

Üblicherweise bilden Vorrichtungen zum Bilden von Stapeln, das Ende von Förderströmen, das heisst, alle im Förderstrom zugeführten Druckprodukte werden gestapelt. Die Kapazität der die Stapel weiterfördernden oder weiterverarbeitenden Vorrichtungen ist dabei an die Förderleistung des Förderstromes anzupassen oder es sind vorgängig Weichen in den Förderstrom einzubauen, die den Förderstrom auf verschiedene stapelbildende Vorrichtungen leiten. Die Anzahl von Druckprodukten, die eine Vorrichtung zum Weiterfördern oder Weiterverarbeiten (z.B. Umschnüren oder Verpacken) von Stapeln pro Zeiteinheit verarbeiten kann, ist im wesentlichen konstant und die Zuführung problemlos zu handhaben, solange alle gebildeten Stapel im wesentlichen gleich viele Druckprodukte umfassen. Sollen nun aber Stapel mit sehr verschiedenen Zahlen von Druckprodukten gebildet werden (z.B. Normpakete und Spitzenpakete oder Pakete mit Normgrösse aus Druckprodukten verschiedener Dicke), kommt es zu sehr schnellen Veränderungen in der Kapazität, mit der die stapelverarbeitenden Vorrichtungen Druckprodukte aufnehmen können. Dadurch entstehen Schwierigkeiten, die noch verschärft werden, wenn die Stapelbildung auch noch auf die Eigenschaften der einzelnen Druckprodukte ausgerichtet werden muss (individualisierte Druckprodukte).Typically, devices for forming stacks form the end of Flow rates, that is, all of the print products fed into the flow rate are stacked. The capacity of the stacks that convey or further process the stacks Devices is based on the delivery rate of the flow to be adapted or switches have to be installed beforehand in the flow, the flow to different stacking devices conduct. The number of printed products that convey a device or further processing (e.g. strapping or packaging) of stacks can process per unit of time is essentially constant and the Feeder easy to handle as long as all the stacks formed are essentially include the same number of printed products. But should now stack with very different numbers of printed products are formed (e.g. standard packages and top packages or packages of standard size from printed products different thickness), there are very rapid changes in capacity, with which the stack processing devices receive printed products can. This creates difficulties that are exacerbated when the stacking also depends on the properties of each Print products must be aligned (individualized print products).

In der Publikation CH-667854 (bzw. US-4683708) ist eine Anlage beschrieben, mit der aus einem zugeführten Schuppenstrom Druckprodukte wahlweise in einen Stapelschacht abgeworfen werden oder in eine weitere stapelbildende Vorrichtung weitergefördert werden. In der weiteren Vorrichtung werden die gebildeten Stapel sofort in Folien gepackt und weitergefördert. Diese Anlage ist nur anwendbar, wenn die Hauptmenge der Druckprodukte in den Stapelschacht abgeworfen wird, oder, wenn die Förderleistung des zugeführten Schuppenstromes auf die momentane Kapazität der beiden, insbesondere der weiteren stapelbildenden Vorrichtung abgestimmt wird. Es ist mit der beschriebenen Vorrichtung auch nicht möglich, einzelne Druckprodukte aus dem Schuppenstrom auszuschleusen und in den Stapelschacht abzuwerfen, das heisst, individualisierte Druckprodukte individuell zu behandeln. Aus diesen Gründen bleibt die beschriebene Anlage auf ein sehr schmales Anwendungsspektrum beschränkt.A system is described in publication CH-667854 (or US-4683708), with the print products optionally from a shed stream supplied be dropped into a stacking shaft or into another stacking one Device will be promoted. In the further device, the formed stack immediately packed in foils and conveyed on. This facility is only applicable when the majority of the printed products in the stacking shaft is dropped, or when the delivery rate of the supplied Scale flow to the current capacity of the two, especially the another stack-forming device is tuned. It is with the one described Device also not possible to print individual products from the To discharge the shingled stream and throw it into the stacking shaft means treating individualized print products individually. From these For reasons, the system described remains on a very narrow range of applications limited.

Es ist nun die Aufgabe der Erfindung, ein Verfahren aufzuzeigen, mit dem aus einem Förderstrom von Druckprodukten einzelne Druckprodukte oder Gruppen von aufeinanderfolgenden Druckprodukten gezielt ausgeschleust und einzeln oder als gestapelte Gruppe einer Weiterverarbeitung zugeführt werden können. Das Verfahren soll einfach sein und an verschiedenste Vorgaben anpassbar. Ferner ist es die Aufgabe der Erfindung, eine Vorrichtung zur Durchführung des Verfahrens zu schaffen.It is now the object of the invention to demonstrate a method with which from a flow of print products individual print products or Groups of successive printed products are specifically ejected and individually or as a stacked group for further processing can. The process should be simple and meet a wide range of requirements customizable. Furthermore, it is the object of the invention to provide a device for To carry out the procedure.

Diese Aufgabe wird gelöst durch das Verfahren und die Vorrichtung, wie sie in den Patentansprüchen definiert sind.This object is achieved by the method and the device as it is are defined in the claims.

Gemäss dem erfindungsgemässen Verfahren ist der Förderstrom, in dem die Druckprodukte zugeführt werden, ein Strom von quer zu ihren Hauptflächen einzeln an Haltemitteln hängend geförderten Druckprodukten. Dieser Förderstrom wird über eine Stapelfläche gefördert, wobei die Stapelfläche derart angeordnet ist, dass sie von unten in den Förderstrom ragt und dass jedes der Druckprodukte mindestens mit seinem unteren Teil vorübergehend an die Stapelfläche oder an ein bereits an der Stapelfläche anliegendes Druckprodukt angelegt wird. Soll nun ein Druckprodukt dem sich auf der Stapelfläche bildenden Stapel zugefügt werden, wird es in dem Moment, in dem es an der Stapelfläche anliegt oder unmittelbar vorher, vom Haltemittel losgelassen. Durch die Schwerkraft fällt das losgelassene Druckprodukt, geführt von der Stapelfläche oder von bereits auf der Stapelfläche gestapelten Druckprodukten nach unten bis auf ein Fussstück und steht dort auf.According to the inventive method, the flow in which the Printed products are fed a stream from across their major surfaces Printed products individually suspended from holding devices. This flow is conveyed over a stacking surface, the stacking surface being such is arranged that it protrudes from below into the flow and that each of the Print products at least with its lower part temporarily to the Stacking surface or to a printed product already lying on the stacking surface is created. Now you want a print product on the stacking surface forming stack will be added the moment it is on the Stacking surface abuts or immediately before, released from the holding means. The released printed product, guided by the, falls through gravity Stacking area or of printed products already stacked on the stacking area down to a foot piece and gets up there.

Für den Weitertransport eines auf der Stapelfläche gebildeten Stapels wird beispielsweise das Fussstück entfernt und das oder die auf dem Fussstück aufstehenden Druckprodukte werden durch die Schwerkraft fallend einer Weiterverarbeitung, beispielsweise einer Verpackung zwischen Folienbahnen zugeführt. Für den Weitertransport eines auf der Stapelfläche gebildeten Stapels, der aus mehreren Druckprodukten oder auch aus nur einem Druckprodukt bestehen kann, kann dieser auch mit geeigneten Mitteln seitwärts von der Stapelfläche gestossen werden.For the further transport of a stack formed on the stacking surface for example, the foot piece removed and the one or more standing on the foot piece Print products are subjected to gravity for further processing, for example, a packaging fed between film webs. For the further transport of a stack formed on the stack surface, that from several printed products or from just one printed product can exist, this can also with suitable means sideways from the Stacking surface to be pushed.

Die Ausschleusung und die Stapelbildung können in einem Verfahrensschritt vereinigt werden. In einer derartigen Verfahrensvariante werden Produkte, die nicht ausgeschleust, das heisst nicht auf der Stapelfläche deponiert werden sollen, von den Haltemitteln im Bereiche der Stapelfläche nicht losgelassen sondern am Haltemittel hängend weiter gefördert und damit über die Stapelfläche gezogen.The removal and stacking can be done in one process step be united. In such a process variant, products that not ejected, that is, not to be deposited on the stacking surface should not be released from the holding means in the area of the stacking surface but conveyed further by the holding means and thus over the stacking surface drawn.

Die Ausschleusung und die Stapelbildung können aber auch in zwei voneinander getrennten Schritten durchgeführt werden, dadurch, dass vor der Stapelfläche eine Weiche vorgesehen wird, an der die auszuschleusenden Druckprodukte samt ihren Haltemitteln aus dem Förderstrom ausgeschleust und gegen die Stapelfläche gefördert werden, während Druckprodukte, die nicht ausgeschleust werden, auf der ursprünglichen Förderstrecke weitergefördert werden. In einem derartigen Verfahren ist es auch möglich, die Druckprodukte zwischen Ausschleusweiche und Stapelfläche zu puffern, um Kapazitätsengpässe in der Stapelweiterverarbeitung zu überbrücken.The discharge and stacking can also be done in two separate steps are carried out in that in front of the stacking surface a switch is provided on which the printed products to be discharged ejected together with their holding means from the flow and are conveyed against the stacking surface while printed products that are not are rejected, conveyed on the original conveyor line will. In such a process it is also possible to print the products to buffer between the discharge switch and the stacking area to avoid capacity bottlenecks to bridge in batch processing.

Figures 5 and 6
schematic representations of two exemplary embodiments of devices for performing the inventive method.

Figuren 1 bis 4 zeigen schematisch das Funktionsprinzip des erfindungsgemässen Verfahrens anhand von aufeinanderfolgenden Stadien eines Förderstromes mit einer Förderrichtung F, in welchem Förderstrom hängend von Haltemitteln 1 gehaltene Druckprodukte 2 im wesentlichen quer zu ihren Hauptflächen gefördert werden. Aus dem Förderstrom werden einzelne Druckprodukte 2 ausgeschleust und als Stapel 3 weitergefördert. Zu diesem Zwecke ist eine von unten in den Förderstrom ragende Stapelfläche 4 vorgesehen, deren obere Kante 4.1 (im wesentlichen senkrecht zur Papierebene) in einer parallel zu den Hauptflächen der Druckprodukte liegenden Ebene liegt und an deren unterem Ende, das unterhalb des Förderstromes positioniert ist, ein Fussstück 5 angeordnet ist. Die Stapelfläche 4 kann senkrecht ausgerichtet sein oder derart schief, dass ihre obere Kante in Förderrichtung F gegenüber dem unteren Ende vorlaufend ist. FIGS. 1 to 4 schematically show the functional principle of the method according to the invention on the basis of successive stages of a conveying flow with a conveying direction F, in which conveying stream, depending on the holding means 1, printed products 2 are conveyed essentially transversely to their main surfaces. Individual printed products 2 are discharged from the conveying flow and conveyed on as a stack 3. For this purpose, a stacking surface 4 projecting from below into the conveying flow is provided, the upper edge 4.1 (essentially perpendicular to the plane of the paper) lying in a plane lying parallel to the main surfaces of the printed products and at its lower end, which is positioned below the conveying flow, a foot piece 5 is arranged. The stacking surface 4 can be oriented vertically or obliquely in such a way that its upper edge leads in the conveying direction F towards the lower end.

Figur 1 zeigt einen Ausschnitt aus dem Förderstrom in einem Stadium, in dem das Druckprodukt 2.1, das durch das Haltemittel 1.1 hängend gehalten wird, in einer Position angelangt ist, in der es an der Stapelfläche 4 anliegt. Das Druckprodukt 2.1 soll nicht ausgeschleust werden. Aus diesem Grunde passiert das Haltemittel 1.1 die Stelle über der Stapelfläche ohne geöffnet zu werden und das Druckprodukt 2.1 wird über die Stapelfläche gezogen. Figure 1 shows a section of the flow at a stage in which the printed product 2.1, which is held suspended by the holding means 1.1, has reached a position in which it rests on the stacking surface 4. The printed product 2.1 should not be removed. For this reason, the holding means 1.1 passes the point above the stacking area without being opened and the printed product 2.1 is pulled over the stacking area.

Figur 2 zeigt das Druckprodukt 2.1, das die Stapelfläche 4 passiert hat und weitergefördert wird. Das folgende Druckprodukt 2.2, das vom Haltemittel 1.2 gefördert wird, ist jetzt an der Stapelfläche 4 angelangt. Da das Druckprodukt 2.2 ausgeschleust werden soll, wird das Haltemittel 1.2 geöffnet und das Druckprodukte 2.2 fällt geführt von der Stapelfläche 4 nach unten, bis es auf dem Fussstück 5 aufsteht (Figur 3). Figure 2 shows the printed product 2.1, which has passed the stacking surface 4 and is being conveyed on. The following printed product 2.2, which is conveyed by the holding means 1.2, has now reached the stacking surface 4. Since the printed product 2.2 is to be discharged, the holding means 1.2 is opened and the printed product 2.2 is guided downwards from the stacking surface 4 until it stands on the foot piece 5 (FIG. 3).

Figur 3 zeigt, wie ein weiter folgendes Druckprodukt 2.3 ebenfalls auf der Stapelfläche 4 bzw. auf dem bereits auf der Stapelfläche anliegenden Druckprodukt 2.2 deponiert wird, dadurch, dass das Haltemittel 1.3 geöffnet wird. FIG. 3 shows how a further following printed product 2.3 is also deposited on the stacking surface 4 or on the printed product 2.2 already resting on the stacking surface, by opening the holding means 1.3.

Figur 4 zeigt, wie durch Verschiebung des Fussstückes 5 der Stapel 3, der sich auf der Stapelfläche 4 gebildet hat und der im dargestellten Beispiel aus den Druckprodukten 2.2 und 2.3 besteht, durch die Schwerkraft weitergefördert wird (Pfeil W), wofür vorteilhafterweise eine geeignete, nicht dargestellt Führung vorzusehen ist. Die Stapelfläche wird dadurch leer und, wenn das Fussstück 5 wieder in seine ursprüngliche Position gebracht ist (Pfeil R), wieder bereit für die Bildung eines neuen Stapels, die beispielsweise durch die dargestellte Ausschleusung des folgenden Druckproduktes 2.4 beginnt. FIG. 4 shows how, by moving the foot piece 5, the stack 3, which has formed on the stacking surface 4 and which in the example shown consists of the printed products 2.2 and 2.3, is conveyed further by gravity (arrow W), for which a suitable, not shown leadership is to be provided. The stack area is thereby empty and, when the foot piece 5 is brought back into its original position (arrow R), ready for the formation of a new stack, which begins, for example, by the illustrated discharge of the following printed product 2.4.

Selbstverständlich können anstelle von Stapeln, die aus einer Mehrzahl von Druckprodukten bestehen, auch einzelne Druckprodukte (Stapel mit nur einem Druckprodukt) von der Stapelfläche 4 weitergefördert und weiterverarbeitet werden.Of course, instead of stacks consisting of a plurality of Print products exist, also individual print products (stacks with only a printed product) from the stacking surface 4 and further processed will.

In den Figuren 1 bis 4 ist jeweils ein Ausschnitt aus einem Förderstrom dargestellt. Es ist ohne weiteres möglich, auf die in den Figuren dargestellte Stapelfläche 4 folgend eine weitere Stapelfläche oder eine Serie von weiteren Stapelflächen anzuordnen, über denen Druckprodukte, die an der ersten Stapelfläche nicht ausgeschleust wurden, losgelassen und gestapelt werden.1 to 4 each show a section of a flow. It is easily possible on the stacking surface shown in the figures 4 following another stacking area or a series of further stacking areas arrange over which printed products that are on the first stacking surface have not been removed, released and stacked.

In den Figuren 1 bis 4 sind die Druckprodukte schematisch dargestellt als einmal gefaltete Bogen mit einer Faltkante, die nach oben gerichtet ist, das heisst von den Haltemitteln gehalten wird. In der gleichen Weise sind auch andere Druckprodukte handhabbar, die beispielsweise aus mehreren ineinandergefalteten Bogen bestehen, oder auch Druckprodukte, die mehrseitig und geheftet oder gebundenen sind. Dabei können die Druckprodukte mit der Faltkante bzw. dem gehefteten oder gebundenen Rücken gegen oben, gegen unten oder auch seitlich angeordnet gefördert werden.In Figures 1 to 4, the printed products are shown schematically as once folded sheet with a folded edge that is directed upwards, the means is held by the holding means. Are in the same way too other print products can be handled, for example made up of several folded ones Sheet exist, or printed products that are multi-sided and are stapled or bound. The printed products can be used with the Folded edge or the stapled or bound back towards the top, against promoted below or laterally.

Der Hauptvorteil des erfindungsgemässen Verfahrens, wie es in den Figuren 1 bis 4 dargestellt ist, besteht darin, dass es derart einfach ist und dass die für seine Durchführung notwendige Vorrichtung ebenfalls sehr einfach ist.The main advantage of the method according to the invention, as shown in FIG. 1 4 to 4 is that it is so simple and that for its implementation necessary device is also very simple.

Diese Vorrichtung besteht im wesentlichen aus einer Förderstrecke, die beispielsweise als Transportkette mit Greifern zur hängenden Förderung von einzelnen Druckprodukten realisiert ist, und aus einer oder mehreren Stapelflächen mit einem verschiebbaren Fussstück oder einem anderen geeigneten Mittel zum Entfernen eines auf der Stapelfläche gebildeten Stapels. Ferner sind Steuermittel vorzusehen, mit denen die Greifer in einer Position im Bereiche über der Stapelfläche geöffnet werden können, und gegebenenfalls Führungsmittel, mit denen Druckprodukte aus geöffneten Greifern geführt werden, womit ein unkontrolliertes Mitschleppen der Druckprodukte durch die sich entfernenden Greifer vermieden wird. Ein derartiges Führungsmittel ist beispielsweise eine Führungskulisse oder Führungsband und wird für auszuschleusende Produkte in den Förderstrom bewegt (siehe Figur 5) oder ist stationär angeordnet in Fällen, in denen alle Druckprodukte ausgeschleust werden.This device consists essentially of a conveyor line, for example as a transport chain with grabs for hanging conveying of individual printed products, and one or more stacking surfaces with a sliding foot piece or another suitable one Means for removing a stack formed on the stacking surface. Further control means are to be provided with which the grippers are in one position in the area can be opened above the stacking surface, and if necessary Guide means with which printed products are guided out of open grippers with which an uncontrolled dragging of the printed products through the moving gripper is avoided. Such a guide is, for example, a guide backdrop or a guide band and is used for those to be diverted Products moved in the flow (see Figure 5) or is arranged stationary in cases where all printed products are rejected will.

Figur 5 zeigt eine beispielhafte Ausführungsform einer Vorrichtung zur Durchführung des erfindungsgemässen Verfahrens. Diese weist eine Kette 10 (schematisch durch eine Linie dargestellt) auf, die in Förderrichtung F über eine Förderstrecke bewegt wird. An der Kette 10 sind äquidistante Greifer (Haltemittel 1) angeordnet, an denen gefaltete Druckprodukte 2 hängend über eine Stapelfläche 4 gefördert werden. Über der Stapelfläche 4 ist ein Mittel 11 zum Öffnen der Greifer installiert, welches Mittel 11 zum individuellen Öffnen vorbestimmter Greifer ansteuerbar ist. FIG. 5 shows an exemplary embodiment of a device for carrying out the method according to the invention. This has a chain 10 (shown schematically by a line) which is moved in the conveying direction F over a conveying path. Equidistant grippers (holding means 1) are arranged on the chain 10, on which folded printed products 2 are conveyed suspended over a stacking surface 4. A means 11 for opening the grippers is installed above the stacking surface 4, which means 11 can be controlled for the individual opening of predetermined grippers.

Die Förderstrecke (Verlauf der Transportkette 10) kann zur Erleichterung der Weiterförderung von nicht auszuschleusenden Druckprodukten im Bereiche der Stapelfläche 4 nach oben abbiegen, wie dies in der Figur 5 dargestellt ist.The conveyor line (course of the transport chain 10) can facilitate the Further promotion of non-rejectable print products in the area Turn the stacking surface 4 upwards, as shown in FIG. 5.

Die Stapelßäche 4 und das Fussstück 5 der in der Figur 5 dargestellten Vorrichtung zur Durchführung des erfindungsgemässen Verfahrens entsprechen der Stapelfläche und dem Fussstück der Figuren 1 bis 4. Ebenfalls zur Erleichterung der Weiterförderung der nicht auszuschleusenden Druckprodukte kann die Stapelfläche 4 in ihrer Höhe verschiebbar (beispielsweise parallel zu ihrer Ausrichtung) angeordnet sein, wie dies durch den Doppelpfeil V angedeutet ist. Eine derart verschiebbare Stapelfläche 4 wird für ein auszuschleusendes Druckprodukt in eine obere, für ein nicht auszuschleusendes Druckprodukt in eine untere Position verschoben, wozu sie mit einem entsprechend ansteuerbaren Antrieb wirkverbunden ist.The stacking surface 4 and the foot piece 5 of the device shown in FIG. 5 correspond to the implementation of the method according to the invention the stacking surface and the foot piece of Figures 1 to 4. Also for relief the further conveyance of the non-rejecting printed products the stacking surface 4 can be displaced in height (for example parallel to their orientation) can be arranged, as indicated by the double arrow V. is. A stackable surface 4 which is displaceable in this way is used for a discharge surface Print product into an upper one, for a print product that cannot be discharged shifted to a lower position, which is why with a corresponding controllable drive is operatively connected.

Die Figur 5 zeigt auch Führungsmittel 16 zur Führung von auszuschleusenden Druckprodukten aus geöffneten Greifern. Diese Führungsmittel sind derart auszugestalten, dass sie für auszuschleusende Druckprodukte in den Förderstrom bewegbar und für nicht auszuschleusende Druckprodukte aus dem Förderstrom entfernbar sind. Sie sind beispielsweise realisiert als Paar von Führungszylindern, die beidseitig der Greifer angeordnet sind und in ihrer ausgefahrenen Position (Figur 5) ein Druckprodukt aus einem geöffneten Greifer führen und in ihrer eingefahrenen Position nicht auszuschleusende Druckprodukte passieren lassen.FIG. 5 also shows guide means 16 for guiding those to be discharged Printed products from open grippers. These guide means are like this to design that they are in the flow for printed products to be discharged movable and for non-rejecting printed products from the Flow are removable. For example, they are realized as a pair of Guide cylinders, which are arranged on both sides of the gripper and in their extended position (Figure 5) a printed product from an open Guide the gripper and do not discharge it in its retracted position Let print products pass.

Ketten mit Greifern und ansteuerbare Mittel zum Öffnen der Greifer, wie sie in der Figur 5 schematisch dargestellt sind, sind beispielsweise in den Patentschriften CH-644816 (bzw. US-4381056, F113), EP-0557680 (bzw. US-5388820, F328) oder US-5395151 (F343) derselben Anmelderin beschrieben und brauchen aus diesem Grunde an dieser Stelle nicht im Detail beschrieben zu werden. Dasselbe gilt für Führungsmittel zum Führen von auszuschleusenden Druckprodukten aus geöffneten Greifern, die beispielsweise in den Patentschriften CH-648261 (bzw. US-4445681, F123) oder CH-654275, F128) beschrieben sind.Chains with grippers and controllable means for opening the grippers as they do 5 are shown schematically, for example, in the patents CH-644816 (or US-4381056, F113), EP-0557680 (or US-5388820, F328) or US-5395151 (F343) by the same applicant and need for this reason it cannot be described in detail here. The same applies to guidance means for guiding those to be removed Printed products from open grippers, for example in the patents CH-648261 (or US-4445681, F123) or CH-654275, F128) are.

Figur 6 zeigt eine weitere beispielhafte Ausführungsform einer Vorrichtung zur Durchführung des erfindungsgemässen Verfahrens. Die Förderstrecke ist in diesem Falle als Schiene 12 oder Schienenanordnung (schematisch als Linie dargestellt) realisiert, auf der individuelle Transportmittel 13, die je ein Haltemittel 1, z.B. einen Greifer tragen, individuell transportierbar sind. Die Schiene 12 verzweigt sich in einer steuerbaren Weichenstelle 14 in eine Schiene 12.1 zur Weiterförderung von Transport- und Haltemitteln mit nicht auszuschleusenden Druckprodukten und in eine über die Stapelfläche führende Schiene 12.2, auf die Transport- und Haltemittel, die auszuschleusende Druckprodukte fördern, geleitet werden. FIG. 6 shows a further exemplary embodiment of a device for carrying out the method according to the invention. In this case, the conveyor line is implemented as a rail 12 or rail arrangement (shown schematically as a line) on which individual transport means 13, each carrying a holding means 1, for example a gripper, can be transported individually. The rail 12 branches in a controllable switch point 14 into a rail 12.1 for the further conveyance of transport and holding means with printed products which cannot be discharged and into a rail 12.2 which leads over the stacking surface and onto which transport and holding means which convey printed products to be discharged are guided.

Die Schiene 12.2 kann beispielsweise abwärts gerichtet sein und ein steuerbares Arretiermittel 15, beispielsweise in Form eines ansteuerbaren Freigabe-, Takt- und Zählrades, aufweisen, an welchem Arretiermittel die durch die Schwerkraft zugeförderten Transportmittel gestoppt und gepuffert werden und nach Bedarf gegen das Mittel 11 zum Öffnen der Haltemittel 1 entlassen werden. Da auf der Schiene 12.2 nur auszuschleusende und auf der Stapelfläche 4 zu stapelnde Druckprodukte zugefördert werden, müssen alle Haltemittel 1 über der Stapelfläche geöffnet werden, sodass das Mittel 11 zum Öffnen nicht ansteuerbar sein muss. Es kann beispielsweise als stationäre Steuerkulisse ausgebildet sein, die mit entsprechenden Steuerrollen an den Haltemitteln kooperiert.The rail 12.2 can for example be directed downwards and a controllable one Locking means 15, for example in the form of a controllable release, Clock and counter wheel, on which locking means by the Gravity-fed means of transport are stopped and buffered and release against the means 11 for opening the holding means 1 as required will. Since on the rail 12.2 only to be discharged and on the stacking surface 4 to be stacked printed products, all holding means must be 1 are opened above the stacking surface, so that the means 11 for Opening does not have to be controllable. For example, it can be used as a stationary Control link be formed with the corresponding control roles on the Holding means cooperated.

Die in der Figur 6 dargestellte Stapelfläche entspricht im wesentlichen der Stapelfläche wie sie im Zusammenhang mit den Figuren 1 bis 4 beschrieben wurde. Da gemäss der in der Figur 6 dargestellten Variante keine nicht aus dem Förderstrom auszuschleusende Druckprodukte über die Stapelfläche 4 gezogen werden müssen, kann diese eine Position einnehmen, die für die Ausschleusung optimal ist, ein Darüberziehen von Druckprodukten aber verunmöglicht.The stacking area shown in FIG. 6 corresponds essentially to that Stacking surface as described in connection with Figures 1 to 4 has been. Since none according to the variant shown in FIG. 6 is not sufficient printed products to be discharged from the flow via the stacking surface 4 must be pulled, this can take a position that is for the ejection is optimal, but covering printed products is impossible.

Systeme von Schienen, Weicherstellen und darauf individuell laufenden Transportmitteln mit Haltemitteln sind beschrieben beispielsweise in den Patentschriften CH-382768 (bzw. US-3032341, F2), CH-569197 (bzw. US-3948551, F62), CH-596061 (bzw. US-4039182, F82) oder aus den Schweizerischen Patentanmeldungen 1816/96 (F434) und 1818/96 (F436) und brauchen aus diesem Grunde an dieser Stelle keine detaillierte Beschreibung.Systems of rails, soft points and individually running on them Means of transport with holding means are described for example in the Patents CH-382768 (or US-3032341, F2), CH-569197 (or US-3948551, F62), CH-596061 (or US-4039182, F82) or from the Swiss Patent applications 1816/96 (F434) and 1818/96 (F436) and need for this reason, no detailed description at this point.
