Description

Die Erfindung betrifft eine Einrichtung nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a device according to the preamble of patent claim 1.

Sammeleinrichtungen der genannten Art werden in der Druckweiterverarbeitung zum Sammeln von Druckprodukten, wie Druckbogen, Karten, CD/DVD-ROM oder anderen flächigen Erzeugnissen zu losen Materialzusammenstellungen eingesetzt. Unter Sammeleinrichtung sind dabei Züsammentragmaschinen, Sammelhefter und Einsteckmaschinen zu verstehen. Entlang einer horizontal verlaufenden Förderstrecke sind Zuführvorrichtungen angeordnet, die je mit einer Sorte der zu sammelnden Druckprodukte beschickt werden. Der Transport der Materialzusammenstellungen innerhalb der Förderstrecke erfolgt dabei mittels an einem umlaufend angetriebenen Zugmittel befestigten Mitnehmern. Die Förderrichtung der Sammeleinrichtung kann je nach Bauart längs oder quer zur Richtung des Rückens stehen. Die Gestaltung der Auflagemittel entlang der Förderstrecke ist abhängig von der jeweiligen Anwendung.Collecting devices of the type mentioned are used in print finishing for collecting printed products, such as printed sheets, cards, CD / DVD-ROM or other sheet products to loose material compositions. Under collecting means are Züsammentragmaschinen, saddle stitchers and insertion machines to understand. Along a horizontal conveyor line feeding devices are arranged, which are each loaded with a variety of printed products to be collected. The transport of the material compositions within the conveyor line is carried out by means of attached to a circumferentially driven traction means drivers. Depending on the design, the conveying direction of the collecting device can be longitudinal or transverse to the direction of the back. The design of the support means along the conveyor line depends on the particular application.

An einer Zusammentragmaschine ist das Auflagemittel L-förmig gestaltet und besteht aus einer in etwa senkrechten Führungswand, an der die Druckprodukte mit ihrem Rückenbereich anliegen und einem zur Führungswand hin geneigten Bodenteil. In der Rückenlängsrichtung sind Mitnehmer oder Anschläge vorgesehen, nach denen die Druckprodukte ausgerichtet werden. Dadurch sind die Bogenzusammenstellungen am Rücken und in Rückenlängsrichtung ausgerichtet. Eine Einrichtung nach dem Stand der Technik ist beispielsweise in der CH 446 269 offenbart. An einem umlaufend angetriebenen Zugmittel in gleichen Abständen befestigte Mitnehmer bilden zusammen eine Fördervorrichtung, die die Materialzusammenstellungen durch den Förderkanal schiebt. Die Materialzusammenstellungen sind in Förderrichtung exakt nach dem sie schiebenden Mitnehmer ausgerichtet. Vor jeden Mitnehmer wird auf seinem Weg durch den Förderkanal von jeder Zuführvorrichtung je ein Druckprodukt zugeführt, sodass am Ende der Sammelstrecke jedem Mitnehmer ein komplett zusammengetragener, loser Buchblock zugeordnet ist. Es ist weiterhin bekannt, die Fördervorrichtung so zu gestalten, dass die Druckprodukte in der Richtung quer zum Rücken gesammelt, respektive gefördert werden.At a gathering machine, the support means is L-shaped and consists of an approximately vertical guide wall, against which the printed products abut with their backs and an inclined towards the guide wall bottom part. In the back longitudinal direction drivers or stops are provided, according to which the printed products are aligned. As a result, the sheet compositions are aligned on the back and in the back longitudinal direction. A device according to the prior art is for example in the CH 446 269 disclosed. At a circumferentially driven traction means fixed at equal intervals driver together form a conveyor which pushes the material compositions through the conveyor channel. The material combinations are aligned in the conveying direction exactly after the driver pushing them. Before each driver is fed on its way through the conveyor channel of each feeder ever a printed product, so at the end of the collection each catch a completely assembled, loose book block is assigned. It is also known to design the conveyor so that the printed products are collected in the direction across the back, respectively conveyed.

Druckprodukte zum Sammelheften werden auf einer dachförmigen Auflage rittlings aufliegend gesammelt und müssen vor dem Ablegen auf die Fördervorrichtung einzeln mittig geöffnet werden. Ihre Lage quer zur Fördervorrichtung ist durch die Spitze der dachförmigen Auflage und einem Anschlag oder Mitnehmer in der Rückenlängsrichtung definiert.Print products for saddle stitching are collected on a roof-shaped support astride resting and must be opened individually centrally before depositing on the conveyor. Its position transversely to the conveying device is defined by the tip of the roof-shaped support and a stop or catch in the back longitudinal direction.

Bei Sammeleinrichtungen zum Einstecken sind entlang einer Förderstrecke Zuführvorrichtungen zum Zuführen von Druckprodukten angeordnet. Dabei wird zuerst das sogenannte Hauptblatt zugeführt und in der Mitte geöffnet, sodass eine Art Tasche entsteht, in die die einzusteckenden Druckprodukte von den nachfolgenden Zuführvorrichtungen eingefügt werden können. Der Antrieb der Fördervorrichtung erfolgt taktsynchron zu der an die in Förderrichtung nachfolgende Weiterverarbeitungsmaschine, beispielsweise einen Klebebinder oder Sammelhefter.In collecting devices for insertion along a conveyor line supply devices for supplying printed products are arranged. In this case, the so-called main sheet is first fed and opened in the middle, so that a kind of pocket is created, in which the einzusteckenden printed products can be inserted by the subsequent feeding devices. The drive of the conveyor takes place isochronous to the subsequent processing machine in the conveying direction, for example, an adhesive binder or saddle stitcher.

Dies kann durch einen mit der nachfolgenden Weiterverarbeitungsmaschine synchronisiert laufenden, geregelten Elektromotor oder mechanisch durch Ankupplung an den Zentralantrieb der nachfolgenden Verarbeitungsmaschine erfolgen. Die Zuführvorrichtungen sind einzeln, gruppenweise oder zentral angetrieben. Damit die zugeführten Druckprodukte an der korrekten Stelle auf die Materialzusammenstellungen abgelegt werden, müssen die Antriebe der Zuführvorrichtungen zur Fördervorrichtung synchronisiert laufen. Je nach Antriebsart der Zuführvorrichtungen erfolgt dies durch eine mechanische Kopplung oder bei motorischem Antrieb durch eine Antriebssteuerung.This can be done by a synchronized with the subsequent processing machine running, controlled electric motor or mechanically by coupling to the central drive of the subsequent processing machine. The feeders are driven individually, in groups or centrally. In order for the supplied printed products to be deposited on the material compilations at the correct location, the drives of the feed devices to the conveyor device must run synchronized. Depending on the drive type of the feeders, this is done by a mechanical coupling or motor drive by a drive control.

Nachteilig an Vorrichtungen nach dem Stand der Technik ist, dass die Antriebe der Zuführvorrichtungen und der Fördervorrichtung starr miteinander gekoppelt sind. Dies hat zur Folge, dass infolge von Teilungsfehlern der Fördervorrichtung der Summenfehler eines Mitnehmers zur Bogenzuführvorrichtung mit wachsender Distanz zum Antrieb der Fördervorrichtung zunimmt.A disadvantage of devices according to the prior art is that the drives of the feeders and the conveyor are rigidly coupled together. This has the consequence that due to pitch errors of the conveyor of the sum error of a driver to Bogenzuführvorrichtung with increasing distance to drive the conveyor increases.

Da das Zugmittel der Fördervorrichtung in der Regel eine Kette ist, nehmen die Toleranzen durch Verschleiss der Kette laufend zu. Ebenfalls nicht berücksichtigt werden Deformationen in den Antriebsorganen infolge der zu übertragenden Drehmomente und Kräfte, die zusätzlich zu einer Verschlechterung der Synchronisationsgenauigkeit beitragen. Bei der Verarbeitung von Standard Druckprodukten gleichen Formats können im Falle von längeren Sammeleinrichtungen bereits Beeinträchtigungen der Betriebssicherheit auftreten.Since the traction means of the conveyor is usually a chain, the tolerances by wear of the chain are constantly increasing. Also not taken into account are deformations in the drive members due to the torques and forces to be transmitted, which in addition contribute to a deterioration of the synchronization accuracy. When processing standard print products of the same format, operational reliability may already be impaired in the case of longer collection devices.

Die vorveröffentlichte US 5 031 891 beschreibt ein Verfahren und eine Vorrichtung für ein selektives Sammeln unterschiedlicher Druckprodukte, wobei die Druckprodukte jeweils durch steuerbare Entnahmevorrichtungen resp. Anleger einzelnen Förderabschnitten einer Fördervorrichtung zugeführt werden. Die Anleger sind durch einen Rechner gesteuert, der einen Speicher mit Leseradressen sowie der Lieferabfolge und die auszuwählenden Teile eines Druckproduktes für bestimmte Leser aufweist.The pre-published US 5 031 891 describes a method and an apparatus for selectively collecting different printed products, wherein the printed products respectively by controllable sampling devices resp. Suppliers individual conveyor sections are fed to a conveyor. The investors are controlled by a computer which has a memory with reader addresses as well as the delivery sequence and the parts to be selected from a print product for certain readers.

Die vorveröffentlichte EP - A - 1 065 074 vermittelt ein Verfahren und eine Vorrichtung zur Verbesserung des richtigen Zeitpunktes zwischen der Entnahme von Druckprodukten durch Anleger und den Mitnehmerfingern einer Förderkette an einer Sammelstrecke. Dabei ist an den Enden der Sammelstrecke einer Einstechmaschine zur Feststellung des Durchlaufs der Mitnehmerfinger jeweils ein Sensor vorgesehen, mit denen der Verzug der Förderkette durch verspätetes Eintreffen der Mitnehmerfinger an jedem Anleger erfasst wird, so dass der richtige Zeitpunkt zwischen Entnahme und Mitnehmerfinger korrigiert werden kann.The pre-published EP-A-1 065 074 provides a method and a device for improving the timing between the withdrawal of printed products by investors and the driving fingers of a conveyor chain on a collecting line. In each case, a sensor is provided at the ends of the collection section of a Einstechmaschine for determining the passage of the driver fingers, with which the delay of the conveyor chain is detected by late arrival of the driver fingers on each investor, so that the right time between removal and driver finger can be corrected.

Die vorpublizierte EP - A - 1 357 069 befasst sich mit einem Bankautomat, der ein erstes Transportband aufweist, das einen Stapel von Bogen entlang eines Förderweges transportiert, und der einen zweiten Förderabschnitt aufweist, der an einer Zuführstelle in den ersten Förderweg mündet, an der eine die Bogen ausrichtende Vorrichtung vorgesehen ist.The prepublished EP-A-1 357 069 is concerned with an automatic cash dispenser having a first conveyor belt which transports a stack of sheets along a conveying path, and which has a second conveying section which opens at a feed point into the first conveying path at which a sheet-aligning device is provided.

Der Erfindung liegt die Aufgabe zugrunde, das zuletzt zugeführte Druckprodukt in Förderrichtung präzise ausgerichtet auf das oberste Druckprodukt der sich darunter befindenden Materialzusammenstellung zu fördern.The invention has for its object to promote the last supplied printed product in the conveying direction precisely aligned with the uppermost printed product of the underlying material composition.

Die Aufgabe wird erfindungsgemäss durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst.The object is achieved according to the invention by the characterizing features of claim 1.

Die Erfindung wird anschliessend unter Bezugnahme auf die Zeichnung, auf die bezüglich aller in der Beschreibung nicht näher erwähnten Einzelheiten verwiesen wird, anhand von Ausführungsbeispielen erläutert. In der Zeichnung zeigen:

Die in den Fig. 1 und Fig. 4 dargestellten Sammeleinrichtungen 1 bestehen im Wesentlichen aus einer Förderstrecke 27 und Zuführvorrichtungen 26, die entlang der Förderstrecke 27 angeordnet sind. Die Förderstrecke 27 verfügt über Auflagemittel 39 (in Fig. 1 nicht dargestellt) auf denen Materialzusammenstellungen 23 aus Druckprodukten 3 und Beilagen 33 entstehen und in Förderrichtung F verschoben werden, und ein Arbeitstrum 37 einer Fördervorrichtung 6 umlaufender Zugmittel 4, an welchen in regelmässigen Abständen Mitnehmer 5 befestigt sind, die Aufnahmestellen 25 für die Materialzusammenstellungen 23 bilden. An Förderabschnitte 35 der Förderstrecke 27 werden durch Zuführvorrichtungen 26 Druckprodukte 3 oder Beilagen 33 geliefert, wobei jedem Förderabschnitt 35 mindestens eine Zuführvorrichtung 26 zugeordnet ist. Die Sammeleinrichtung 1 nach der Fig. 1 könnte beispielsweise für das Sammeln von Materialzusammenstellungen 23 für einen Klebebinder und die Sammeleinrichtung 1 nach der Fig. 4 für einen Sammelhefter eingesetzt werden. Beim Sammelprozess für die Klebebindung werden die verschiedenen Druckprodukte 3 durch die entlang der Förderstrecke 27 angeordneten Zuführvorrichtungen 26 in einem Kanal aufeinander geschichtet, sodass am Ende der Förderstrecke 27 komplette Materialzusammenstellungen 23 verfügbar sind. Beim Sammelprozess für die Sammelheftung nach Fig. 4 werden die Druckprodukte 3 in geöffnetem Zustand auf einer durch Auflagemittel 39 gebildeten dachförmigen Auflage rittlings gesammelt. Das Zugmittel 4 wird mittels einer Antriebsvorrichtung 7, beispielsweise eines Motors, angetrieben.The in the Fig. 1 and Fig. 4 The collecting devices 1 shown essentially consist of a conveying path 27 and feed devices 26, which are arranged along the conveying path 27. The conveyor line 27 has support means 39 (in Fig. 1 not shown) on which material compilations 23 of printed products 3 and supplements 33 are produced and displaced in the conveying direction F, and a working belt 37 of a conveying device 6 circulating traction means 4, which are fixed at regular intervals driver 5, the receiving points 25 for the material compositions 23 form , At conveying sections 35 of the conveying path 27, printing products 3 or inserts 33 are supplied by feeding devices 26, wherein each conveying section 35 is assigned at least one feeding device 26. The collecting device 1 after the Fig. 1 For example, for the collection of material assemblies 23 for an adhesive binder and the collecting device 1 according to the Fig. 4 be used for a saddle stitcher. In the collecting process for the adhesive binding, the various printed products 3 are stacked on one another in a channel by the feed devices 26 arranged along the conveying path 27, so that complete material combinations 23 are available at the end of the conveying path 27. During the collection process for the saddle stitching according to Fig. 4 the printed products 3 in the open state are astride collected on a roof-shaped support formed by support means 39. The traction means 4 is driven by means of a drive device 7, for example a motor.

Die Zuführvorrichtungen 26 werden durch Anleger 2 gebildet, die die Druckprodukte 3 aus Stapeln vereinzeln und an Zuführförderer 28 abgeben, mittels derer die Druckprodukte 3 positionsgenau auf die sich bildenden Materialzusammenstellungen 23 abgelegt werden. Anleger 2 sind dem Fachmann in verschiedenen Ausführungsformen bekannt. In den Figuren sind die Anleger 2 als Trommelanleger dargestellt. Das unterste Druckprodukt 3 resp. die unterste Beilage 33 eines Stapels werden dabei mittels Saugmitteln partiell vom Stapel abgetrennt und anschliessend durch an den Trommeln 32 angeordneten Greifern erfasst, vom Stapel wegtransportiert und an eine als Zuführförderer 28 ausgebildete Zuführstrecke 43 abgegeben. Als Zuführförderer 28 eignen sich beispielsweise ein umlaufendes Oberband 30 und ein mit diesem zusammenwirkenden Unterband 31, zwischen denen die Druckprodukte 3 kraftschlüssig eingespannt gefördert werden. Ebenfalls denkbar wäre eine umlaufende Kette, mit einer Mehrzahl von an dieser befestigten Greifern, die die Druckprodukte 3 vom Anleger 2 bis zu der Zusammenführungsstelle 36 fördern und auf das oberste Druckprodukt 3 der darunter liegenden Materialzusammenstellung 23 ablegen würden. Üblicherweise liegen die Druckprodukte 3 am die Materialzusammenstellung 23 schiebenden Mitnehmer 5 an und sind somit auf dieser Seite exakt ausgerichtet und referenziert. Formatkleinere Druckprodukte 3, wie auch beispielsweise formatkleinere Beilagen 33, müssen jedoch meistens mit einem Positions-Sollwert a - gleich oder grösser 0 - zum obersten Druckprodukt 3 einer Materialzusammenstellung 23 an der Förderstrecke zugeführt werden. Die gegeneinander zu positionierenden Beilagen 33 undThe feed devices 26 are formed by feeders 2, which singulate the printed products 3 from stacks and deliver them to feed conveyors 28, by means of which the printed products 3 are placed with exact position on the forming material assemblies 23. Feeder 2 are known in the art in various embodiments. In the figures, the investors 2 are shown as a drum feeder. The lowest printed product 3 resp. The bottom shim 33 of a stack are thereby partially separated from the stack by means of suction means and subsequently detected by grippers arranged on the drums 32, transported away from the stack and delivered to a feed line 43 designed as a feed conveyor 28. For example, a circulating upper belt 30 and a lower belt 31 cooperating therewith, between which the printed products 3 are conveyed in a force-fit manner, are suitable as feed conveyors 28. Also conceivable would be a circumferential chain, with a plurality of grippers attached to this, which would promote the printed products 3 from the feeder 2 to the merging point 36 and deposited on the uppermost printed product 3 of the underlying material composition 23. Usually, the printed products are 3 on the material assembly 23 sliding driver 5 and are thus aligned and referenced on this page exactly. Format smaller print products 3, as well For example, smaller-size supplements 33, however, usually have to be supplied to the top printed product 3 of a material combination 23 on the conveyor line with a desired position value a equal to or greater than 0. The supplements to be positioned 33 and

Druckprodukte 3 können mit unterschiedlicher Polarität elektrostatisch aufgeladen werden, wodurch sich eine wenigstens temporäre Verbindung zwischen ihnen ergibt. Jede Zuführvorrichtung 26 verfügt über einen eigenen Regelantrieb 29, der mindestens den Zuführförderer 28 und in einer bevorzugten Ausführung auch den Anleger 2 antreibt. Der Regelantrieb 29 wird durch einen Motor 8 mit Lagesensor 10 und einer Servosteuerung 9 gebildet, die miteinander über eine Rückführung 11 und eine Energiezuführung 12 verbunden sind. Alternativ könnte der Regelantrieb 29 auch durch einen Schrittmotor und eine Schrittmotorsteuerung gebildet sein, wobei in diesem Fall auf den Lagesensor 10 und die Rückführung 11 verzichtet werden könnte. Bekannt sind weiterhin Antriebssysteme, bei denen durch die Servosteuerung 9 direkt die Position des Rotors ermittelt werden kann, womit der Lagesensor 10 ebenfalls entfallen kann. Eine weitere denkbare Lösung ist, als Motor 8 einen Linearmotor einzusetzen. Die Servosteuerung 9 ist mit einer Steuervorrichtung 13 verbunden, von der sie laufend mindestens die Sollwerte 14 der Lage des Antriebs erhält und die Istwerte 15 an die Steuervorrichtung 13 zurückgibt. Zur Ermittlung der Lage der Antriebsvorrichtung 7 für die Mitnehmer 5 ist die Steuervorrichtung 13 über die Signalleitung Feintakt 19 mindestens mit einem Feintakt Sensor 17 eines Wegmesssystems 16 verbunden. Bekanntlich können die Funktionen der Steuervorrichtung 13 und der Servosteuerung 9 in einem einzigen Gerät zusammengefasst sein. Dies ändert jedoch nichts an den vorgängig beschriebenen Abläufen und Funktionen.Printed products 3 can be electrostatically charged with different polarity, resulting in an at least temporary connection between them. Each feeder 26 has its own variable speed drive 29, which drives at least the feed conveyor 28 and in a preferred embodiment also the feeder 2. The variable speed drive 29 is formed by a motor 8 with position sensor 10 and a servo control 9, which are connected to each other via a return 11 and a power supply 12. Alternatively, the variable speed drive 29 could also be formed by a stepper motor and a stepper motor controller, in which case the position sensor 10 and the feedback 11 could be dispensed with. Also known are drive systems in which the position of the rotor can be determined directly by the servo control 9, whereby the position sensor 10 can also be dispensed with. Another conceivable solution is to use a linear motor as motor 8. The servo control 9 is connected to a control device 13, from which it continuously receives at least the desired values 14 of the position of the drive and returns the actual values 15 to the control device 13. To determine the position of the drive device 7 for the driver 5, the control device 13 is connected via the signal line Feintakt 19 at least one Feintakt sensor 17 of a position measuring system 16. As is known, the functions of the control device 13 and the servo control 9 can be combined in a single device. However, this does not change the previously described procedures and functions.

Im Bereich vor der Zusammenführungsstelle 36 eines Druckprodukts 3 oder einer Beilage 33 mit dem darunter liegenden Druckprodukt 3 sind Positionssensoren 22 für die Messung der Position, mindestens des obersten Druckprodukts 3 einer Materialzusammenstellung 23 und Positionssensoren 24 für die Messung der Position des zuzuführenden Druckprodukts 3 oder der Beilage 33 vorgesehen. Aufgrund der beiden Messwerte der Sensoren 22,24 berechnet die Steuervorrichtung 13 die zu erwartende relative Position (Positions-Istwert a) von zuzuführendem Druckprodukt 3 oder Beilage 33 zum obersten Druckprodukt 3 der Materialzusammenstellung 23. Alternativ zur Messung der Position des obersten Druckprodukts 3 einer Materialzusammenstellung 23 kann mit einem Positionssensor 21 die Position des Mitnehmers 5 gemessen werden, an dem das oberste Druckprodukt 3 einer Materialzusammenstellung 23 anliegt. Die Regelantriebe 29 laufen somit als Slave lagegeregelt nach der Antriebsvorrichtung 7 der Fördervorrichtung 6, die den Master bildet. Solche Systeme sind unter dem Begriff "elektrische Welle" bekannt. Durch Messung der effektiv zu erwartenden Position a eines zuzuführenden Druckprodukts 3 oder einer Beilage 33 zum obersten Druckprodukt 3 der Materialzusammenstellung 23 undIn the area in front of the merging point 36 of a printed product 3 or an insert 33 with the underlying printed product 3 are position sensors 22 for the measurement of the position, at least of the uppermost printed product 3 of a material composition 23 and position sensors 24 for the measurement of the position of the supplied printed product 3 or Supplement 33 provided. On the basis of the two measured values of the sensors 22, 24, the control device 13 calculates the expected relative position (actual position value a) of the printed product 3 or insert 33 to the uppermost printed product 3 of the material combination 23. Alternatively to the measurement of the position of the uppermost printed product 3 of a material combination 23 can be measured with a position sensor 21, the position of the driver 5, to which the uppermost printed product 3 of a material composition 23 is applied. The control drives 29 thus run as a slave position-controlled according to the drive device 7 of the conveying device 6, which forms the master. Such systems are known by the term "electrical wave". By measuring the effectively expected position a of a supplied printed product 3 or a supplement 33 to the top printed product 3 of the material composition 23 and

Vergleich mit dem Positions-Sollwert a ist es möglich, den Sollwert 15 des Regelantriebs 29 entsprechend zu korrigieren und damit die zuvor ermittelte Abweichung von Positions-Istwert a zu Positions-Sollwert a zu kompensieren. Geometrische Fehler der Fördervorrichtung 6 infolge Deformationen, Herstellungstoleranzen und Verschleiss werden somit laufend erfasst und kompensiert, sodass die zuzuführenden Beilagen 33 und Druckprodukte 3 in Förderrichtung F exakt auf das oberste Druckprodukt 3 einer Materialzusammenstellung 23 abgelegt werden. Die Positionssensoren 21,22,24 sind möglichst nahe vor der Zusammenführungsstelle 36 positioniert, aber mindestens soweit, dass auch bei maximaler Produktionsgeschwindigkeit der Regelantrieb 29 einen neu errechneten Sollwert erreichen kann. Wird die Maschine ausgeschaltet, wird zwangsläufig auch die ganze Steuerung inaktiv. Werden jetzt Veränderungen durch manuelle Eingriffe an der Maschine vorgenommen, wird dies die Steuervorrichtung 13 nicht erkennen können. Auf diese Weise können die Regelantriebe 29 ihre Referenz verlieren, die erst wieder durch die Förderung von Druckprodukten 3 und Beilagen 33 sowie Erfassung derer Lage mit Hilfe der vorgängig beschriebenen Sensorik und Steuervorrichtungen 13 wieder gewonnen werden kann. Um dies zu vermeiden, können Referenztakte an den Zuführvorrichtungen 26 und der Fördervorrichtung 6 generiert und mittels der Signalleitung 20 der Referenztakt der Fördervorrichtung 6 und mit der Signalleitung 42 der Referenztakt der Zuführvorrichtung 26 an die Steuervorrichtung 13 übertragen werden. Die Referenztakte werden je einmal pro Maschinentakt durch den Referenztaktsensor 40 der Fördervorrichtung 6 und Referenztaktsensoren 41 der Zuführvorrichtungen 26 erzeugt. Die zeitliche Lage innerhalb eines Maschinentaktes ist durch mechanische Einstellungen definiert. Somit ist es möglich, Regelantriebe 29 ohne Förderung von Druckprodukten 3 oder Beilagen 33 auf die Fördervorrichtung 6 annähernd zu synchronisieren. Die dabei erreichbare Genauigkeit entspricht derjenigen von Vorrichtungen nach dem Stand der Technik. Weiterhin ist denkbar, die Position a mit Hilfe des Positionssensors 22 der Materialzusammenstellungen und dem Referenztaktsensor 41 der Zuführvorrichtung zu bestimmen. In dieser Betriebsart wird die mögliche Genauigkeit nicht ganz erreicht, jedoch gegenüber Vorrichtungen nach dem Stand der Technik wesentlich übertroffen.Comparison with the position setpoint a, it is possible to correct the target value 15 of the variable speed drive 29 accordingly and thus to compensate for the previously determined deviation from actual position value a to position setpoint a. Geometric errors of the conveying device 6 as a result of deformations, manufacturing tolerances and wear are thus continuously detected and compensated so that the supplements 33 and printed products 3 to be supplied are deposited in the conveying direction F exactly on the topmost printed product 3 of a material composition 23. The position sensors 21, 22, 24 are positioned as close as possible in front of the merging point 36, but at least to the extent that the regulating drive 29 can reach a newly calculated setpoint value even at maximum production speed. If the machine is switched off, inevitably the whole control system becomes inactive. If changes are now made by manual intervention on the machine, the control device 13 will not be able to recognize this. In this way, the control drives 29 may lose their reference, which can only be recovered again by the promotion of printed products 3 and supplements 33 and recording derer position using the previously described sensors and control devices 13. To avoid this, reference clocks can be generated at the feed devices 26 and the conveyor device 6 and transmitted by the signal line 20 of the reference clock of the conveying device 6 and the signal line 42 of the reference clock of the feeder 26 to the control device 13. The reference clocks are generated once per machine cycle by the reference clock sensor 40 of the conveyor device 6 and reference clock sensors 41 of the feeders 26. The timing within a machine cycle is defined by mechanical settings. Thus, it is possible to approximately synchronize control drives 29 without conveying printed products 3 or supplements 33 to the conveying device 6. The achievable accuracy corresponds to that of devices according to the prior art. Furthermore, it is conceivable to determine the position a by means of the position sensor 22 of the material combinations and the reference clock sensor 41 of the feeding device. In this mode of operation, the possible accuracy is not quite achieved, but significantly exceeded that of prior art devices.

Während dem Zusammenführen der Beilagen 33 oder der Druckprodukte 3 mit dem darunter liegenden Druckprodukt 3 muss dieses nicht zwingend auf der Materialzusammenstellung 23 aufliegen, sondern kann vorerst auf einer Auflage 34 gleiten, die oberhalb des Auflagemittels 39 angeordnet ist. Die Förderung kann trotzdem durch die Mitnehmer 5 erfolgen, wie dies in Fig. 3 dargestellt ist.During the merging of the inserts 33 or the printed products 3 with the underlying printed product 3, this does not necessarily have to rest on the material composition 23, but can initially slide on a support 34, which is arranged above the support means 39. The promotion can still be done by the driver 5, as in Fig. 3 is shown.

Weiterhin ist denkbar, mit Hilfe von nach der Zusammenführungsstelle 36 stromabwärts angeordneten Bilderkennungssystemen die Lage einer Beilage 33 oder eines Druckprodukts 3 relativ zu dem darunter liegenden Druckprodukt 3 zu erkennen. Damit ist es möglich, in Förderrichtung F und/oder quer dazu versetzt oder schief zugeführte Beilagen 33 zu erkennen und beim Überschreiten eines zulässigen Grenzwertes auszuschleusen.Furthermore, it is conceivable to detect the position of a supplement 33 or of a printed product 3 relative to the underlying printed product 3 with the aid of image recognition systems arranged downstream of the merging point 36. This makes it possible to detect in the conveying direction F and / or transversely offset or incorrectly supplied supplements 33 and auszuschleusen when exceeding an allowable limit.

In der Fig. 4 ist eine alternative Sammeleinrichtung 1 dargestellt, wie sie beispielsweise für die Beschickung einer Heftmaschine 38 eines Sammelhefters eingesetzt wird. Die Funktionsweise der Antriebe ist dabei identisch mit derjenigen in einer Zusammentragmaschine für einen Klebebinder. Wesentlicher Unterschied ist, dass die Druckprodukte 3 bei der Sammelheftung in geöffnetem Zustand auf einer dachförmigen Förderstrecke 27 rittlings aufeinander gelegt und in dieser Art gesammelt werden.In the Fig. 4 an alternative collecting device 1 is shown, as used for example for feeding a stapling machine 38 of a saddle stitcher. The operation of the drives is identical to that in a gathering machine for an adhesive binder. The main difference is that the printed products 3 in the saddle stitching in the open state on a roof-shaped conveying path 27 are placed astride and collected in this way.
