Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Herstellung von klebegebundenen, aus einem Buchblock und einem Umschlag gebildeten Druckerzeugnissen, bei dem die Buchblocks jeweils in einer von mehreren umlaufenden Klammern einer Klebebindevorrichtung zur Bearbeitung und Beleimung ihres Rückens an Bearbeitungsstationen der Klebebindevorrichtung vorbeigeführt werden. Anschliessend wird dem beleimten Rücken taktsynchron gesteuert ein Umschlag zugeführt. Dabei ist nach der Zusammenführung des Umschlags mit dem Buchblock ein Messvorgang zur Erfassung einer gegenseitigen Ist-Lage von Umschlag zu Buchblock vorgesehen.The invention relates to a method and a device for the production of adhesive-bonded, formed from a book block and an envelope printed products in which the book blocks are guided past in each case in one of several circumferential brackets of an adhesive binder for processing and gluing of their back to processing stations of the adhesive binding device. Subsequently, the envelope is clocked synchronously fed the glued back. In this case, after the merging of the envelope with the book block, a measuring process for detecting a mutual actual position of envelope to book block is provided.

Bei der industriellen Fertigung von klebegebundenen Druckerzeugnissen wie Zeitschriften, Katalogen, Taschenbüchern oder ähnlichen Produkten werden in einem ersten Schritt bedruckte Druckbogen zu losen Buchblocks zusammengetragen und anschliessend in einem Klebebinder im Rückenbereich bearbeitet, beleimt und mit einem Umschlag verklebt, d.h. gebunden. Schnell laufende Klebebinder weisen dabei eine Vielzahl von in regelmässigen Abständen angeordneten, in einer geschlossenen Bahn umlaufende Klammern auf, in die die losen Buchblocks eingespannt in Rückenlängsrichtung von einer Zufuhrstation zu einer Freigabestation transportiert werden. Der Antrieb der Klammern kann durch ein über ein Antriebsrad angetriebenes Zugmittel, an dem die Klammern befestigt sind oder direkt durch an den Klammern angeordnete Zahnstangen erfolgen, die über ein Antriebszahnrad antreibbar sind. Mittels zwischen der Zufuhrstation und Freigabestation ortsfest angeordneten Bearbeitungsstationen, wie beispielsweise Rückenbearbeitungsstationen, Beleimungsstationen, Umschlagstation und Anpressstation werden die leicht mit ihrem Rückenbereich aus den Klammern nach unten vorstehenden Buchblocks während der Förderung bearbeitet. Eine der letzten Bearbeitungsstationen in einem Klebebinder ist die Umschlagstation. Die Genauigkeit, mit der die Umschläge in Rückenlängsrichtung relativ zum Buchblock anbringbar sind, stellt dabei ein wesentliches Qualitätsmerkmal eines gebundenen Druckerzeugnisses dar. Die Buchblocks werden nach ihrer Zufuhr in die Klammern in Rückenlängsrichtung exakt ausgerichtet. Die Umschläge werden mittels eines in einer geschlossenen Bahn umlaufenden Förderers zu der Zusammenführungsstelle von Umschlag und Buchblock gefördert und durch eine Anpressstation von unten an den Buchblockrücken und seitlich angepresst. Der Antrieb des Umschlagförderers ist entweder mechanisch oder mittels eines eigenen Antriebs synchron mit dem Antrieb der Klammern verbunden. Die erreichbare Genauigkeit von Umschlag zu Buchblock wird dabei wesentlich beeinträchtigt durch Fehler in den Antriebsmitteln, vor allem den Zugmitteln der Antriebsmittel, bedingt durch Fertigungsungenauigkeiten und Verschleiss. Zusätzlich kann die Genauigkeit durch ändernde Produktionsbedingungen, wie Produktionsgeschwindigkeit, Leimfilmdicke, Leimauftragstemperatur oder Anpresskraft der Umschlaganpressung negativ beeinflusst werden.In the industrial production of glued-bound printed products such as magazines, catalogs, paperbacks or similar products, in a first step printed signatures are collected into loose book blocks and then processed in an adhesive binder in the back area, glued and glued to an envelope, ie bound. Fast-moving perfect binders have a plurality of arranged at regular intervals, in a closed path circulating brackets, in which the loose book block clamped in Back longitudinal direction are transported from a supply station to a release station. The drive of the clamps can be effected by a driven by a drive wheel traction means on which the brackets are attached or directly by arranged on the brackets racks, which are drivable via a drive gear. By means of stationary between the feed station and release station processing stations, such as back processing stations, Beleimungsstationen, handling station and press station easily edited with their back area from the brackets down the above book block during promotion. One of the last processing stations in an adhesive binder is the handling station. The accuracy with which the envelopes are attached in the back longitudinal direction relative to the book block, thereby represents an essential quality feature of a bound printed product. The book blocks are aligned exactly after their supply into the brackets in the back longitudinal direction. The envelopes are conveyed by means of a conveyor circulating in a closed path to the merging point of the envelope and book block and are pressed by a pressure station from below to the book block back and side. The drive of the envelope conveyor is connected either mechanically or by means of its own drive synchronously with the drive of the clamps. The achievable accuracy of envelope to book block is significantly affected by errors in the drive means, especially the traction means of the drive means due to manufacturing inaccuracies and wear. In addition, the accuracy can be adversely affected by changing production conditions, such as production speed, glue film thickness, glue application temperature or pressing force of the Umschlaganpressung.

Die CH 475098 A5 beschreibt ein Verfahren, bei dem die Lage der Umschläge im Verhältnis zu den Buchblocks durch eine Anpassung der Zuführorgane der Umschläge an die Klammern gesteuert wird. Die Zuführorgane sind an einer zyklisch arbeitenden Anpressstation angeordnet und werden vor der Zusammenführung des Umschlags mit dem Buchblock nach der Klammer ausgerichtet. Für diesen Ausrichtvorgang steht ein relativ kurzes Zeitfenster zur Verfügung, sodass bei hohen Taktzahlen der Umschlag durch hohe Beschleunigungen deformiert werden kann und somit die geforderte Ausrichtgenauigkeit nicht mehr erreichbar ist.The CH 475098 A5 describes a method in which the position of the envelopes relative to the book blocks is controlled by an adjustment of the feeders of the envelopes to the staples. The feeders are located at a cyclically operating press station and are aligned with the book block after the staple prior to merging the envelope. For this alignment process a relatively short time window is available, so that at high cycle times, the envelope can be deformed by high accelerations and thus the required alignment accuracy is no longer achievable.

Die CH 586115 A5 beschreibt ein Verfahren, bei dem höhere Taktzahlen möglich sind, indem eine Umschlagförderkette direkt an einer Klammer referenziert wird, damit der Umschlag relativ zum Buchblock ausgerichtet werden kann. Auch wenn dadurch die Beschleunigungen und die damit verbundenen negativen Auswirkungen auf die Druckerzeugnisse reduziert werden, ist dieses Verfahren nicht für Taktzahlen über 12000 T/h geeignet.The CH 586115 A5 describes a method in which higher beats are possible by referencing an envelope conveyor chain directly to a bracket so that the envelope can be aligned relative to the book block. Although this reduces the accelerations and the associated negative effects on the printed products, this method is not suitable for cycles above 12000 T / h.

In der DE 10221542 A1 , die den Oberbegriff des Anspruchs 1 oder 4 offenbart, wird eine Vorrichtung offenbart, bei der die Klammern und wenigstens eine Bearbeitungsstation unabhängig voneinander antreibbar sind. Dabei wird ein Messsystem zur Positionserfassung der Klammern bzw. der Buchblocks in der Nähe dieser Bearbeitungsstation zu deren Steuerung im Sinne einer Positionieraufgabe vorgesehen. Dadurch lässt sich eine Bearbeitungsstation, beispielsweise die Umschlagzuführung zu der Klammer, bzw. zu dem Buchblock ausrichten.In the DE 10221542 A1 Disclosing the preamble of claim 1 or 4, there is disclosed an apparatus in which the staples and at least one processing station are independently drivable. In this case, a measuring system for detecting the position of the brackets or the book blocks in the vicinity of this processing station is provided for their control in the sense of a positioning task. This makes it possible to align a processing station, for example, the envelope feed to the clip, or to the book block.

Mit derartigen Lösungen nach dem Stand der Technik lassen sich Abweichungen der Umschläge zu den Buchblocks, verursacht durch Toleranzen in den Antrieben und Zugmitteln für den Antrieb der Klammern und die Umschlagzuführung, lediglich vor deren Zusammenführung vermeiden. Abweichungen die während und/oder nach der Zusammenführung der Umschläge mit den Buchblocks erfolgen, lassen sich mit Vorrichtungen nach dem Stand der Technik nicht erfassen und ausgleichen. Derartige Abweichungen können beispielsweise dadurch verursacht werden, dass Parameter wie z.B. die Produktionsgeschwindigkeit des Klebebinders, die Filmdicke oder die Auftragstemperatur des Klebstoffs oder die Anpresskraft des Umschlags an den Buchblock verändert werden.With such prior art solutions, deviations of the envelopes from the book blocks, caused by tolerances in the drives and traction means for driving the clamps and the envelope feed, can be avoided only prior to their merging. Deviations that occur during and / or after the merging of the envelopes with the book block, can not be detected and compensated with devices of the prior art. Such deviations can be caused, for example, by changing parameters such as the speed of production of the perfect binder, the film thickness or the application temperature of the adhesive or the contact force of the envelope to the book block.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zur Herstellung von klebegebundenen Druckerzeugnissen zu schaffen, mit denen auch bei veränderten Produktionsbedingungen eine genaue relative Lage des Umschlages zum Buchblock in Rückenlängsrichtung gewährleistet ist.The invention has for its object to provide a method and apparatus for the production of adhesive bound printed products, with which an accurate relative position of the envelope is guaranteed to the book block in the back longitudinal direction even with changed production conditions.

Die Aufgabe wird erfindungsgemäss dadurch gelöst, dass die Umschlagstation einen Mitnehmer aufweist, welcher den Umschlag zum Buchblock zuführt, die Ist-Lage des Umschlags zum Buchblock mit einer vorgegebenen Soll-Lage verglichen wird und bei Abweichungen der Ist-Lage von der Soll-Lage ein Korrekturwert für eine bestimmte Paarung des den erfassten Umschlag transportierende Mitnehmers und der den erfassten Buchblock transportierenden Klammer ermittelt wird. Dieser Korrekturwert wird abgespeichert und vor dem erneuten Auftreten der bestimmten Paarung von Mitnehmer und Klammer wird eine dem Korrekturwert entsprechende Änderung der Position der Klammer und/oder des Mitnehmers dieser Paarung vorgenommen.The object is achieved according to the fact that the transfer station has a driver which feeds the envelope to the book block, the actual position of the envelope is compared to the book block with a predetermined target position and in case of deviations of the actual position of the desired position Correction value for a particular pairing of the detected envelope transporting the driver and the book block transported the detected staple is determined. This correction value is stored and prior to the re-occurrence of the particular pairing of driver and clamp, a change in the position of the clamp and / or the driver of this pairing is made corresponding to the correction value.

Dieses Verfahren ermöglicht demnach eine Korrektur von Abweichungen die sowohl durch Änderung der Produktionsbedingungen, als auch durch aufgrund des Verschleisses von Antriebselementen auftretendes, längerfristiges Driften hervorgerufen werden.This method thus makes it possible to correct deviations which are caused both by changing the production conditions and by longer-term drift occurring as a result of the wear of drive elements.

Die Bearbeitungsstationen weisen eine Anpressstation und eine stromab angeordnete Freigabestation auf. Vorzugsweise werden bei diesem Verfahren die der jeweiligen Ist-Lage von Umschlag zu Buchblock entsprechende, durch die Messvorrichtung ermittelten Ist-Werte stromab der Anpressstation und besonders vorteilhaft zwischen der Anpressstation und der Freigabestation erfasst.The processing stations have a contact pressure station and a downstream release station. In this method, the actual values determined by the measuring device, which correspond to the respective actual position from cover to book block, are preferably detected downstream of the contact pressure station and particularly advantageously between the contact pressure station and the release station.

Die Klebebindevorrichtung der erfindungsgemässen Vorrichtung weist ebenfalls eine Auswerte- und Steuereinheit auf, in der eine vorgegebene Soll-Lage des Umschlags zum Buchblock speicherbar, mit der Ist-Lage des Umschlags zum Buchblock vergleichbar, eine Abweichung der Ist-Lage von der Soll-Lage feststellbar, ein Korrekturwert für die bestimmte Paarung ermittelbar und abspeicherbar ist. Vor dem erneuten Auftreten der bestimmten Paarung von Mitnehmer und Klammer wird mit der Auswerte- und Steuereinheit eine dem Korrekturwert entsprechende Änderung der Position der Klammer und/oder des Mitnehmers dieser Paarung ermittelt und an einen mit der Auswerte- und Steuereinheit verbundenen Hauptantrieb der Klammern und/oder an eine Antriebsvorrichtung der Umschlagstation weitergegeben.In a device according to the invention for producing adhesively bound printed products formed from a book block and an envelope, the transhipment station has a carrier which feeds the envelope to a book block transported in a clamp. In this case, the driver supplying the envelope form and the clip transporting the book block has a certain mating. The adhesive binding device of the device according to the invention also has an evaluation and control unit, in which a predetermined target position of the envelope to the book block storable, comparable to the actual position of the envelope to the book block, a deviation of the actual position of the desired position determined , a correction value for the particular pairing can be determined and stored. Before re-occurrence of the specific pairing of driver and clamp, the evaluation and control unit determines a change in the position of the clamp and / or the driver of this pairing corresponding to the correction value and to a main drive of the clamps connected to the evaluation and control unit. or passed on to a drive device of the transfer station.

Wie in Fig.1 dargestellt, werden zur Herstellung von klebegebundenen, aus einem Buchblock 1 und einem Umschlag 2 gebildeten Druckerzeugnissen 38 wie Bücher, Broschuren, Zeitschriften etc., zuerst in einer Zusammentragmaschine Druckprodukte zu losen Buchblocks 1 zusammengetragen. Anschliessend werden die Buchblocks in einer nachgeschalteten Klebebindevorrichtung 3 im Bereich ihres Rückens 4 gebunden. Die Klebebindevorrichtung 3 weist m in einer geschlossenen Bahn in regelmässigen Abständen umlaufende, durch ein Zugmittel 5 angetriebene Klammern 6 auf, denen die Buchblocks 1 zur Rückenbearbeitung, -beleimung und zur Anbringung des Umschlags 2 zugeführt werden. Alle Bearbeitungen erfolgen mittels entlang einem Förderweg 36 der Klammern 6 ortsfest angeordneten, hier nur teilweise dargestellten Bearbeitungsstationen 37, in denen die mit dem Rücken 4 nach unten leicht aus den Klammern 6 vorstehenden Buchblocks 1 während ihrer Förderung in einer Förderrichtung F bearbeitet werden. Der Förderweg 36 entspricht dabei dem Weg zwischen einer nicht dargestellten Zufuhrstation, die die Buchblocks 1 in die Klammern 6 zuführt und einer Freigabestation 7, in der die die gebundenen Druckerzeugnisse 38 aus den Klammern 6 entnommen werden. Das Zugmittel 5 wird durch ein Antriebsrad 8 angetrieben, das über eine Antriebswelle 9 mit einem Hauptantrieb 10 der Klebebindevorrichtung 3 verbunden ist.As in Fig.1 shown, for the production of adhesive-bound, formed from a book block 1 and an envelope 2 printed products 38 such as books, brochures, magazines, etc., first collected in a collating machine printed products to loose book block 1. Subsequently, the book blocks are bound in a downstream adhesive binding device 3 in the region of the back 4. The adhesive binding device 3 has m in a closed path at regular intervals circumferential, driven by a pulling means 5 brackets 6, where the book block 1 for back processing, gluing and attaching the envelope 2 are supplied. All processing takes place by means of along a conveying path 36 of the brackets 6 fixedly arranged, here only partially illustrated processing stations 37, in which the back 4 down easily be processed from the brackets 6 above book block 1 during its promotion in a conveying direction F. The conveying path 36 corresponds to the path between a feed station, not shown, which feeds the book block 1 in the brackets 6 and a release station 7, in which the bound printed products 38 are removed from the brackets 6. The traction means 5 is driven by a drive wheel 8, which is connected via a drive shaft 9 with a main drive 10 of the adhesive binding device 3.

In einem ersten Ausführungsbeispiel nach der Fig. 1 weist der Hauptantrieb 10 ein Verteilgetriebe 11 und einen Hauptmotor 12 auf, der das Verteilgetriebe 11 antreibt. Eine im Wesentlichen durch einen Umschlaganleger 13 und eine Umschlagzuführung 14 gebildete Umschlagstation 15 führt die Umschläge 2 den Buchblocks 1 mittels an einer Kette 17 befestigten Mitnehmer 18 taktsynchron gesteuert zu und bildet somit eine der letzten Bearbeitungsstationen 37 der Klebebindevorrichtung 3.In a first embodiment of the Fig. 1 For example, the main drive 10 includes a transfer gear 11 and a main motor 12 that drives the transfer gear 11. A handling station 15 essentially formed by a cover feeder 13 and an envelope feeder 14 guides the envelopes 2 in an isochronously controlled manner to the book block 1 by means of a carrier 18 attached to a chain 17 and thus forms one of the last processing stations 37 of the adhesive binding device 3.

Mittels einer stromabwärts der Umschlagstation 15 angeordneten Anpressstation 24 werden die Umschläge 2 von unterhalb an die Rücken 4 der Buchblocks 1 und seitlich an die Buchblocks 1 angepresst, wobei die Umschläge 2 und/oder die Buchblocks 1 vor dem Anpressen mit Klebstoff beschichtet werden. Am Ende des Förderwegs 36 der Klammern 6, d.h. nach der Anpressstation 24, ist eine Messvorrichtung 28 zur Erfassung der gegenseitigen Position von Umschlag 2 und Buchblock 1 entlang des Rückens 4 vorgesehen. Die durch die Messvorrichtung 28 ermittelten Ist-Werte I werden an eine mit ihr verbundene Auswerte- und Steuereinheit 19 übermittelt, durch diese mit einem Soll-Wert S verglichen und Korrekturwerte K berechnet. Die Bildung der Korrekturwerte K wird im Anschluss an die Vorrichtungsbeschreibung erläutert.By means of a downstream of the transfer station 15 arranged pressing station 24, the envelopes 2 are pressed from below to the back 4 of the book block 1 and laterally to the book block 1, the envelopes 2 and / or the book block 1 are coated with adhesive before pressing. At the end of the conveying path 36 of the clamps 6, i. after the pressing station 24, a measuring device 28 for detecting the mutual position of the envelope 2 and book block 1 along the back 4 is provided. The actual values I determined by the measuring device 28 are transmitted to an evaluation and control unit 19 connected to it, compared with these by a desired value S and calculated correction values K. The formation of the correction values K will be explained after the device description.

In den Fig. 1 und Fig. 2 ist die Messvorrichtung 28 nach der Anpressstation 24, d.h. der vorletzten Bearbeitungsstation 37 angeordnet. Die Messvorrichtung 28 könnte jedoch auch nach der Freigabestation 7 angeordnet sein. Dabei lässt sich das im Bereich der Messstation 28 befindliche Druckerzeugnis 38 eindeutig einer Paarung P einer Klammer 6 mit einem Mitnehmer 18 zuordnen.In the Fig. 1 and Fig. 2 the measuring device 28 is arranged after the pressing station 24, ie the penultimate processing station 37. However, the measuring device 28 could also be arranged after the release station 7. This can be in the Area of the measuring station 28 located printed product 38 clearly assign a pairing P of a bracket 6 with a driver 18.

Die in einem Magazin 16 des Umschlaganlegers 13 aufeinander gestapelten Umschläge 2 werden durch den Umschlaganleger 13 vereinzelt und der Umschlagzuführung 14 übergeben. Diese weist n Mitnehmer 18 auf, die an der umlaufenden Kette 17 in regelmässigen Abständen befestigt sind. Die Kette 17 wird durch eine dem Umschlaganleger 13 zugeordnete und mit der Auswerte- und Steuereinheit 19 verbundene Antriebsvorrichtung 20 taktsynchron zu den Klammern 6 angetrieben. Dabei wird die Antriebsvorrichtung 20 aus einem mit dem Verteilgetriebe 11 über eine Königswelle 31 und einem Elektromotor 21 verbundenen Überlagerungsgetriebe 22 gebildet. Das Überlagerungsgetriebe 22 addiert, die durch den dem Überlagerungsgetriebe 22 zugeordneten, als Stellmotor ausgebildeten Elektromotor 21 erzeugten Drehwinkel mit dem Drehwinkel des Verteilgetriebes 11.The envelopes 2 stacked on each other in a magazine 16 of the envelope feeder 13 are separated by the envelope feeder 13 and transferred to the envelope feeder 14. This has n carrier 18, which are attached to the revolving chain 17 at regular intervals. The chain 17 is driven in a clock-synchronized manner to the clamps 6 by a drive device 20 associated with the envelope feeder 13 and connected to the evaluation and control unit 19. In this case, the drive device 20 is formed from a superposition gear 22 connected to the transfer gear 11 via a king shaft 31 and an electric motor 21. The superposition gear 22 adds, which generated by the superposition gear 22, designed as a servomotor electric motor 21 rotation angle with the rotation angle of the transfer gear 11th

Der Elektromotor 21 ist vorzugsweise als drehwinkelgesteuerter Schrittmotor oder Servomotor ausgebildet, der mit einer mit der Auswerte- und Steuereinheit 19 verbundenen Motorsteuerung 23 verbunden ist. Durch den Einsatz des Elektromotors 21 lassen sich Korrekturen an der gegenseitigen Position der Mitnehmer 18, bzw. der Umschläge 2 zu den Klammern 6, bzw. der in den Klammern 6 eingespannten Buchblocks 1, vornehmen. Dies geschieht unmittelbar vor der Zusammenführung der Umschläge 2 mit den Buchblocks 1 durch die Anpressstation 24. Diese Korrekturen basieren auf der mittels der Messvorrichtung 28 ermittelten Ist-Lage der Umschläge 2 zu den Buchblocks 1 vorgängig zugestellter Druckerzeugnisse 38.The electric motor 21 is preferably designed as a rotational angle-controlled stepper motor or servomotor, which is connected to a motor controller 23 connected to the evaluation and control unit 19. By using the electric motor 21, corrections can be made to the mutual position of the drivers 18, or of the envelopes 2, to the clamps 6 or the book block 1 clamped in the clamps 6. This is done immediately before the merging of the envelopes 2 with the book block 1 by the pressing station 24. These corrections are based on the determined by means of the measuring device 28 actual position of the envelopes 2 to the book block 1 previously delivered printed products 38th

Wird die Auswerte- und Steuereinheit 19 ausgeschaltet, verliert sie die Kontrolle über die Stellung der Mitnehmer 18 zu den Klammern 6. Nach dem erneuten Einschalten der Auswerte- und Steuereinheit 19 ist dieser demnach die Position der Mitnehmer 18 zu den Klammern 6 nicht bekannt, womit zunächst Druckerzeugnisse 38 mit undefinierter Position der Umschläge 2 zu der Buchblocks 1 gefertigt werden, bis nach einer Messung der Abweichungen mit der Messvorrichtung 28 die Abweichungen durch die Auswerte- und Steuereinheit 19 ausgeglichen werden.If the evaluation and control unit 19 is turned off, it loses control of the position of the driver 18 to the brackets 6. After re-switching the evaluation and control unit 19 this is therefore the position of the driver 18 to the brackets 6 not known, thus first printed products 38 are made with undefined position of the envelopes 2 to the book block 1 until after a measurement of the deviations with the measuring device 28, the deviations are compensated by the evaluation and control unit 19.

Um bereits zu Beginn einer Produktion eine definierte Position der Umschläge 2 zu den Buchblocks 1 zu erreichen, sind Mittel für eine Grundeinstellung von Mitnehmern 18 zu den Klammern 6 vorgesehen. Nach Fig. 1 sind dies ein mit dem Hauptantrieb 10 verbundener Referenztaktsensor 33 und ein beim Passieren der Mitnehmer 18 einen Impuls erzeugender Mitnehmersensor 34. Ein Referenztaktgeber 32 ist über ein Referenzgetriebe 35 derart angetrieben, dass er am Referenztaktsensor 33 bei jedem Maschinentakt einen Impuls auslöst. Zum Synchronisieren wird zuerst der Hauptantrieb 10 auf jene Position gefahren, in der der Referenztaktsensor 33 einen Impuls erhält. Anschliessend wird die Antriebsvorrichtung 20 bis auf jene Position gefahren, in der der Mitnehmersensor 34 einen Impuls erhält. Das Synchronisieren kann bei leerer Klebebindevorrichtung 3 erfolgen, sodass bereits bei den ersten zu fertigenden Druckerzeugnissen 38 die Umschläge 2 zu den Buchblocks 1 an der richtigen Position zuführbar sind.In order to achieve a defined position of the envelopes 2 to the book blocks 1 already at the beginning of a production, means for a basic adjustment of drivers 18 are provided to the brackets 6. To Fig. 1 a reference clock 32 is driven via a reference gear 35 such that it triggers an impulse at the reference clock sensor 33 at each machine cycle. For synchronization, first the main drive 10 is moved to the position in which the reference clock sensor 33 receives a pulse. Subsequently, the drive device 20 is moved to that position in which the driver sensor 34 receives a pulse. The synchronization can be done with an empty perfect binding device 3, so that the envelopes 2 can already be fed to the book blocks 1 at the correct position in the first printed products 38 to be produced.

In einem zweiten Ausführungsbeispiel, wie in Fig. 2 dargestellt, weist die Antriebsvorrichtung 20 einen drehwinkelgesteuerten Elektromotor 21 auf, der direkt oder über ein dazwischen geschaltetes Getriebe 25, die Kette 17 antreibt. Der Hauptantrieb 10 treibt über ein Reduktionsgetriebe 26 ausschliesslich das Zugmittel 5 bzw. die Klammern 6 an. Zum synchronen Lauf der Kette 17 d.h. der Mitnehmer 18 zu den Klammern 6 ist am Hauptmotor 12 ein mit der Auswerte- und Steuereinheit 19 verbundener als Lagesensor ausgebildeter Resolver 27 vorgesehen, mit dem die Drehwinkellage des Hauptmotors 12 permanent erfassbar ist.In a second embodiment, as in Fig. 2 1, the drive device 20 has a rotational angle-controlled electric motor 21 which drives the chain 17 directly or via a transmission 25 connected therebetween. The main drive 10 drives via a reduction gear 26 exclusively the traction means 5 and the brackets 6 at. For synchronous running of the chain 17 that is the driver 18 to the brackets 6 is connected to the evaluation and control unit 19 connected as a position sensor resolver 27 is provided on the main motor 12, with which the rotational angle position of the main motor 12 is permanently detectable.

Auf der Basis des Drehwinkels des Hauptmotors 12 folgt der Elektromotor 21 synchron dem Hauptmotor 12. Der Hauptantrieb 10 bildet somit den Master-Antrieb, dem die Antriebsvorrichtung 20 als Slave-Antrieb folgt. Derartige Systeme sind auch unter dem Begriff "Elektrische Welle" bekannt. Je nach Art des Elektromotors 21, kann auch an dessen Antriebswelle ein Resolver gekoppelt sein, der mit der Auswerte- und Steuereinheit 19 oder der Motorsteuerung 23 verbunden ist. Analog zum ersten Ausführungsbeispiel wird durch einen hier nicht dargestellten Referenztaktgeber im Referenztaktsensor 33 ein Impuls pro Maschinenetakt erzeugt. Die Synchronisation der Mitnehmer 18 mit den Klammern 6 kann ebenfalls analog zur Beschreibung des ersten Ausführungsbeispiels erfolgen.On the basis of the rotation angle of the main motor 12, the electric motor 21 follows the main motor 12 in synchronism. The main drive 10 thus constitutes the master drive followed by the drive device 20 as a slave drive. Such systems are also known by the term "electrical wave". Depending on the type of electric motor 21, can also be coupled to the drive shaft, a resolver, which is connected to the evaluation and control unit 19 or the motor controller 23. Analogous to the first exemplary embodiment, a pulse per machine clock is generated in the reference clock sensor 33 by a reference clock, not shown here. The synchronization of the driver 18 with the brackets 6 can also be carried out analogously to the description of the first embodiment.

Nachfolgend wird ein Verfahren beschrieben, mit dem eine genaue Position der Umschläge 2 zu den Buchblocks 1 in Längsrichtung des Rückens 4 erreicht wird. Die durch die Messvorrichtung 28 laufend ermittelten Ist-Werte I werden mit einem, in eine Bedieneinheit 29 eingegebenen und in der Auswerte- und Steuereinheit 19 gespeicherten Soll-Wert S verglichen. Die Abweichungen werden dabei den Paarungen P der beteiligten Klammern 6 und der Mitnehmer 18 zugeordnet. Auf der Basis dieser Abweichungen berechnet die Auswerte- und Steuereinheit 19 für die betreffende Kombination einer Klammer 6 m und eines Mitnehmers 18 n einen Korrekturwert Km.n, für eine Paarung Pm.n der in einer Datenbank der Auswerte- und Steuereinheit 19 gespeichert wird.The following describes a method by which an accurate position of the envelopes 2 to the book blocks 1 in the longitudinal direction of the back 4 is achieved. The actual values I continuously determined by the measuring device 28 are compared with a desired value S entered in an operating unit 29 and stored in the evaluation and control unit 19. The deviations are assigned to the pairings P of the participating brackets 6 and the driver 18. On the basis of these deviations, the evaluation and control unit 19 calculates for the relevant combination of a clamp 6 m and a driver 18 n a correction value K mn for a pairing P mn which is stored in a database of the evaluation and control unit 19.

Fig. 4 zeigt in Tabellenform die den Paarungen P von Klammern 61..m und Mitnehmern 181..n zugeordneten Korrekturwerte K1.1...m.n. An einer neuen Klebebindervorrichtung 3 können die Korrekturwerte K1.1...m.n auf einen beliebigen Wert gesetzt werden, da sie während der Produktion automatisch korrigiert werden. Sinnvollerweise sollte man sie jedoch auf einen Wert setzten, der dem Ist-Wert I in etwa entspricht. Fig. 4 shows in tabular form the correction values K 1.1 ... mn associated with the pairings P of brackets 6 1..m and drivers 18 1..n . On a new adhesive binder device 3, the correction values K 1.1... Mn can be set to any desired value since they are automatically corrected during production. It makes sense, however, to set it to a value that corresponds to the actual value I approximately.

Weist die Klebebindevorrichtung 3 m Klammern 6 und die Kette 17 n Mitnehmer 18 auf, ergibt sich die maximal mögliche Anzahl Paarungen von Klammern 6 und Mitnehmern 18 als das Produkt von Anzahl m der Klammern 6 multipliziert mit der Anzahl n der Mitnehmer 18. Jeder dieser Paarungen P ist in der einen Rechner 30 aufweisenden oder mit einem Rechner 30 verbundenen Auswerte- und Steuereinheit 19 wenigstens eine Speicherstelle zugeordnet, in denen ein zuvor ermittelter Korrekturwert K11 m n abgespeichert ist, der unmittelbar vor dem nächsten Zusammentreffen von Klammer 6 und Mitnehmer 18 derselben Paarung P wirksam wird.If the adhesive binding device has 3 m staples 6 and the chain 17 n driver 18, the maximum possible number of pairings of staples 6 and drivers 18 results as the product of number m of staples 6 multiplied by the number n of drivers 18. Each of these pairings P is in the one computer 30 having or associated with a computer 30 evaluation and control unit 19 associated with at least one memory location in which a previously determined correction value K 11 mn is stored, which becomes effective immediately before the next meeting of bracket 6 and driver 18 of the same pairing P.

In Fig. 3 ist der hintere Bereich eines Buchblocks 1 mit einem daran befestigten Umschlag 2 dargestellt. Das Mass S entspricht dem Soll-Wert S, den der Umschlag 2 über den Buchblock 1 vorstehen soll und das Mass I dem Ist-Wert I, der mit der Messvorrichtung 28 gemessen wird. Die Position des Umschlags 2 zum Buchblock 1 weist demnach eine Abweichung von S-I auf. Nach jeder Messung wird der Korrekturwert K11 m n, beispielsweise mit folgender Formel, neu berechnet: Korrekturwert neu = Korrekturwert alt + Multiplikator M mal S - l ,

Figure imgb0001
was einer Proportionalregelung entspricht. Denkbar sind ebenfalls andere aus der Regeltechnik bekannte Regler. Als Referenzmarke R wird ein Impuls innerhalb eines Maschinentaktes angenommen, der mit dem Hauptantrieb 10 direkt oder indirekt erzeugt wird, beispielsweise ein Impuls des Referenztaktsensors 33.In Fig. 3 is the rear portion of a book block 1 with an attached envelope 2 shown. The dimension S corresponds to the desired value S, which the envelope 2 is to protrude above the book block 1, and the dimension I to the actual value I, which is measured by the measuring device 28. The position of the envelope 2 to the book block 1 therefore has a deviation from SI. After each measurement, the correction value K 11 mn is recalculated, for example using the following formula: correction value New = correction value old + Multiplier M times S - l .
Figure imgb0001
which corresponds to a proportional control. Also conceivable are other controllers known from control technology. As a reference mark R, a pulse within a machine cycle is assumed, which is generated directly or indirectly with the main drive 10, for example a pulse of the reference clock sensor 33.

Das Verfahren wird anschliessend anhand eines Beispiels mit folgenden Annahmen beschrieben: S = 3 mm; I = 1 mm; K4 3 = 3 mm; M = 0.5 The method is then described by way of example with the following assumptions: S = 3 mm; I = 1 mm; K 4 3 = 3 mm; M = 0.5

Dem mit der Klammer 64 geförderten Buchblock 1 wird mit dem Mitnehmer 183 ein Umschlag 2 zugeführt. Der für diese Paarung P4 3 gültige Korrekturwert K43 ist in der Auswerte- und Steuereinheit 19 gespeichert. Die Antriebsvorrichtung 20 wird relativ zum Impuls des Referenztaktsensors 33 um K43 + S = 6 mm verstellt. Der anschliessend am Produkt gemessene Ist-Wert I beträgt 1 mm und somit die Abweichung S - I = 2 mm. Der neue Korrekturwert K4 3 neu wird K43 alt+ M * (S - I) = 3 + 0.5 *(3- 1) = 4 mm. Beim nächsten zeitlichen Zusammentreffen der Paarung P43 von Klammer 64 und Mitnehmer 183 wird das gleiche Verfahren mit dem neuen Korrekturwert K4 3 neu durchgeführt und so fort. Dem Multiplikator M kann ein beliebiger Wert zwischen 0 und 1 zugewiesen werden. Mit einem kleinen Multiplikator M wird die Regelung träger und mit einem grösseren Multiplikator M schneller. Vorzugsweise wird für den Multiplikator M ein Wert von 0.5 gewählt.The funded with the clip 6 4 book block 1 is supplied with the driver 18 3 an envelope 2. The valid for this pairing P 4 3 correction value K 43 is stored in the evaluation and control unit 19. The drive device 20 is adjusted relative to the pulse of the reference clock sensor 33 by K 43 + S = 6 mm. The actual value I measured subsequently on the product is 1 mm and thus the deviation S - I = 2 mm. The new correction value K 4 3 becomes K 43 alt + M * (S - I) = 3 + 0.5 * (3- 1) = 4 mm. At the next time coincidence of the pairing P 43 of bracket 6 4 and driver 18 3 , the same procedure with the new correction value K 4 3 is performed again and so on. The multiplier M can be any value between 0 and 1. With a small multiplier M, the control becomes slower and with a larger multiplier M faster. Preferably, a value of 0.5 is selected for the multiplier M.

Mit dem beschriebenen Verfahren lassen sich sowohl durch Änderung der Produktionsbedingungen verursachte Abweichungen, als auch durch Verschleiss von bspw. als Kette ausgebildeten Antriebselementen hervorgerufene längerfristige Driften korrigieren. Zur Bedienung und Eingabe von relevanten Parametern ist die Auswerte-und Steuereinheit 19 mit der Bedieneinheit 29 verbunden.The described method can be used to correct deviations caused by changes in the production conditions as well as longer-term drifts caused by wear of, for example, drive elements designed as a chain. For operation and input of relevant parameters, the evaluation and control unit 19 is connected to the operating unit 29.

Der Einsatz des für die Klebebindevorrichtung 3 beschriebenen Verfahrens ist nicht auf diese Anwendung beschränkt. Es lässt sich beispielsweise auch für das Anbringen von geklebten Umschlägen in Sammelheftern bei der Fertigung von sogenannten "Square Backs" oder zum Anbringen von Schutzumschlägen in Schutzumschlagmaschinen anwenden.The use of the method described for the adhesive binder 3 is not limited to this application. It can also be used, for example, for the application of glued envelopes in saddle stitchers in the manufacture of so-called "square backs" or for the attachment of dust covers in dust jacket machines.
