Abstract

A process and device are disclosed for setting up a three-cutter machine by adjusting the supply station, the transfer station, the cutting station and the ejector according to a book format to be cut or in order to carry out maintenance work. During a computer-controlled setting up operation predetermined optimal positions for adjusting cutting parameters or for carrying out maintenance work are purposefully adjusted within one or several machine cycles. Static adjustment steps or maintenance steps are then automatically carried out in these positions, controlled by a computer, and/or adjustment steps to be manually carried out are presented on an electronic display device. In the latter case, these steps are then manually carried out and acknowledged by the control computer. Complementary dynamic adjustement steps can be carried out during operation of the three-cutter machine.

Description

Die Erfindung betrifft ein Verfahren bzw. eine Vorrichtung zum Einrichten eines Dreischneiders oder zur Durchführung von Wartungsarbeiten an einem Dreischneider nach dem Oberbegriff des Anspruchs 1 bzw des Anspruchs 7.The invention relates to a method and a device for setting up a three-knife trimmer or for carrying out maintenance work on a three-knife trimmer according to the preamble of claim 1 and claim 7.

Ein Dreischneider ist eine im Buchbindergewerbe eingesetzte Schneidvorrichtung, die drei Schneidmesser, nämlich ein Vordermesser und zwei Seitenmesser umfaßt. Einem solchen Dreischneider werden über eine Zuführstation Bücher zugeführt, die bereits am Rücken gebunden sind. Die Aufgabe des Dreischneiders besteht darin, die Bücher an den Seiten und an der Vorderkante in einem Arbeitsgang auf das endgültige gewünschte Format zu schneiden.A triple cutter is a cutting device used in the bookbinding industry, which comprises three cutting knives, namely a front knife and two side knives. Books that are already bound to the back are fed to such a triple cutter via a feed station. The task of the three-cutter is to cut the books on the sides and on the front edge in one operation to the final desired format.

Da sich die örtlichen Anordnungen der Messer und weitere Schneidparameter nach dem Format der zu schneidenden Bücher und der vom Auftraggeber gewünschten Schnittqualität richten müssen, ist es erforderlich, den Dreischneider vor Durchführung jedes Auftrags einzurichten.Since the local arrangement of the knives and other cutting parameters must be based on the format of the books to be cut and the cutting quality desired by the client, it is necessary to set up the three-knife trimmer before carrying out each job.

Bisher wurden die entsprechenden Arbeiten von der Bedienungsperson manuell durchgeführt, was lange Einrichtzeiten zur Folge hatte, in denen der Dreischneider nicht benutzt werden konnte.So far, the corresponding work has been carried out manually by the operator, which has resulted in long set-up times in which the three-knife trimmer could not be used.

Bisher war es nämlich erforderlich, die entsprechenden Positionen innerhalb der Maschinenumlaufphasen durch Tippbetrieb anzufahren, wobei es von der Geschicklichkeit und Erfahrung der Bedienungsperson abhing, den Antrieb so rechtzeitig abzuschalten, daß nach Eintreten des durch die Antriebsnachlaufzeit verzögerten Stillstandes gerade die gewünschte Position erreicht wurde. Wurde diese Position nämlich überschritten, so war ein neuer Versuch erforderlich, bei dem zumindest eine Maschinenumlaufphase wieder abgewartet werden mußte.So far, it has been necessary to move to the corresponding positions within the machine circulation phases by jog mode, whereby it depended on the skill and experience of the operator to switch off the drive in time so that the desired position was reached after the drive lag time delayed standstill. If this position was exceeded, a new attempt was necessary, in which at least one machine circulation phase had to be waited for again.

In letzter Zeit ist eine deutliche Zunahme von Druckerzeugnissen und Büchern in kleinen Auflagen zu beobachten. Dies führt dazu, daß in der Praxis immer häufiger Aufträge mit verschiedenen Buchformaten abzuwickeln sind. Den Einrichtzeiten kommt daher eine gravierende Bedeutung zu, weil die entsprechenden zeitintensiven Arbeiten im Vergleich zu der Nutzungszeit des Dreischneiders größer werden. Eine normale Einstellung der Schneidparameter von Hand erfordert einen Zeitaufwand von bis zu 30 Minuten.Recently, there has been a significant increase in printed matter and books in short runs. This means that in practice orders with different book formats have to be processed more and more frequently. The set-up times are therefore of great importance because the corresponding time-consuming work increases compared to the usage time of the three-cutter. A normal setting of the cutting parameters by hand takes up to 30 minutes.

Je häufiger bei einem Wechsel des Buchformats die entsprechenden Einrichtungen erforderlich sind, um so mehr leidet darunter die Wirtschaftlichkeit des Betriebes des Dreischneiders.The more often the corresponding facilities are required when changing the book format, the more the economy of the three-cutter operation suffers.

Der Erfindung liegt die Aufgabe zugrunde, das eingangsgenannte Verfahren und die eingangsgenannte Vorrichtung dahingehend zu verbessern, daß die Einstellung der Schneidparameter bzw. die Durchführung von Wartungsarbeiten schneller und präziser vorgenommen werden kann.The invention has for its object to improve the above-mentioned method and device in such a way that the setting of the cutting parameters and the execution of maintenance work can be carried out faster and more precisely.

Diese Aufgabe wird bei einem Verfahren nach dem Oberbegriff des Anspruchs 1 durch die im kennzeichnenden Teil dieses Anspruchs angegebenen Merkmale, und bei einer Vorrichtung nach dem Oberbegriff des Anspruchs 7 durch die im kennzeichnenden Teil des Anspruchs 7 angegebenen Merkmale gelöst.This object is achieved in a method according to the preamble of claim 1 by the features specified in the characterizing part of this claim, and in a device according to the preamble of claim 7 by the features specified in the characterizing part of claim 7.

Durch das erfindungsgemäße Verfahren wird erreicht, daß zumindest die häufigen und zeitintensiven Einstellmaßnahmen automatisch durchgeführt werden. Sehr hilfreich ist dabei, daß die entsprechenden Positionen innerhalb einer oder mehrerer Maschinenumlaufphasen gezielt angefahren werden, so daß die entsprechenden Einstellmaßnahmen zügig durchgeführt werden können.The inventive method ensures that at least the frequent and time-consuming adjustment measures are carried out automatically. It is very helpful here that the corresponding positions are approached in a targeted manner within one or more machine circulation phases, so that the corresponding adjustment measures can be carried out quickly.

Weiterhin wird durch eine Anzeigevorrichtung dargestellt, welche manuell vorzunehmenden Einstellmaßnahmen gerade anstehen. Auf diese Weise wird es auch ungeübtem Personal möglich, die Einrichtung des Dreischneiders innerhalb sehr kurzer Zeit durchzuführen. Insbesondere braucht die Bedienungsperson nicht durch eigene Versuche die optimale Reihenfolge und die optimalen Positionen herausfinden, in denen die entsprechenden Einstellarbeiten vorzunehmen sind. Darüber hinaus wird durch den vorgegebenen Programmablauf dafür gesorgt, daß Schäden infolge Kollisionen, die bei falscher Reihenfolge der Einstellmaßnahmen auftreten könnten, vermieden werden.Furthermore, a display device shows which manual adjustment measures are currently pending. In this way, even inexperienced personnel can set up the three-knife trimmer in a very short time. In particular, the operator does not need to find out the optimal sequence and the optimal positions in which the corresponding adjustment work is to be carried out by means of his own experiments. In addition, the predetermined program sequence ensures that damage due to collisions, which could occur if the adjustment measures are incorrect, is avoided.

Auch das gezielte Anfahren von Positionen wird ermöglicht, um z. B. im Betrieb auftretende Störungen, wie der Ausbruch der Schneide eines Messers, schnell beheben zu können. In diesem Fall wäre es nicht erforderlich, alle Positionen nacheinander anzufahren, die beim Einrichten nötig wären.The targeted approach to positions is also possible, for. B. faults occurring during operation, such as the breakout of the cutting edge of a knife, can be remedied quickly. In this case, it would not be necessary to move to all the positions one after the other that would be required during setup.

Vorzugsweise ist vorgesehen, daß die Schneidparameter für ein Buchformat, auf das der Dreischneider einzurichten ist, in einem Dialog mit dem Steuerrechner eingegeben werden. Der Umfang der anzufahrenden Positionen und der durchzuführenden Einstellmaßnahmen wird in Abhängigkeit der zuvor eingestellten Schneidparametern vorgenommen.It is preferably provided that the cutting parameters for a book format on which the three-knife trimmer is to be set are entered in a dialog with the control computer. The scope of the positions to be approached and the adjustment measures to be carried out depends on the previously set cutting parameters.

Durch den Dialogbetrieb wird vermieden, daß die Einstellung einzelner Schneidparameter aus Versehen unterbleibt und dann im späteren Schneidbetrieb zu einer hohen Ausschußquote führen könnte. Durch die Vornahme der Einstellmaßnahmen in Abhängigkeit von zuvor eingestellten Schneidparameter läßt sich die Einstellzeit bei Folgeaufträgen mit ähnlichen Formaten teilweise erheblich verkürzen, da nicht stets alle Schneidparameter geändert werden müssen und so ein Teil der Einstellmaßnahmen entfallen kann.The dialog mode prevents the setting of individual cutting parameters from being accidentally omitted and then leading to a high reject rate in the later cutting mode. By taking the setting measures depending on the previously set cutting parameters, the setting time for follow-up orders with similar formats can be reduced considerably, since not all cutting parameters have to be changed and part of the setting measures can be omitted.

Weiterhin ist vorzugsweise vorgesehen, daß die automatisch durchgeführten Einstellmaßnahmen im Sinne einer Regelung mit einem Sollwert-Istwert-Vergleich vorgenommen werden.Furthermore, it is preferably provided that the automatically performed adjustment measures are carried out in the sense of a regulation with a setpoint-actual value comparison.

Dies stellt sicher, daß die gewünschten Maße mit einer hohen Präzision eingehalten werden und damit auch eine hohe Schnittqualität erzielbar ist. Ablese- oder Rechenfehler, wie sie bei der bisher üblichen manuellen Einrichtung des Dreischneiders nicht immer vermeidbar waren, werden hierdurch zuverlässig ausgeschlossen.This ensures that the desired dimensions are adhered to with a high degree of precision and thus a high cut quality can also be achieved. Reading or arithmetic errors, which were not always avoidable in the manual setup of the three-knife trimmer previously used, are thereby reliably excluded.

Bei einer praktischen Ausgestaltung des Verfahrens ist eine Aufteilung der Einstellmaßnahmen in einerseits rechnergesteuert automatisch durchzuführende und andererseits manuell durchzuführende Einstellmaßnahmen vorgenommen. Die rechnergesteuert automatisch durchzuführenden Einstellmaßnahmen betreffen die Maßeinstellung der Übergabestation und der Schneidstation und die manuell durchzuführenden Einstellmaßnahmen betreffen den Austausch von Maschinenteilen und ergänzende Maßeinstellungen.In a practical embodiment of the method, the adjustment measures are subdivided into adjustment measures to be carried out automatically on the one hand under computer control and on the other hand to be carried out manually. The computer-controlled adjustment measures to be carried out relate to the dimension setting of the transfer station and the cutting station, and the adjustment measures to be carried out manually relate to the replacement of machine parts and additional dimension settings.

Durch die Beschränkung der automatisch durchzuführenden Einstellmaßnahmen auf Maßeinstellungen werden die besonders kritischen und mit großen Toleranzen bei einer manuellen Ausführung behafteten Einstellmaßnahmen automatisiert. Der vorrichtungstechnische Mehraufwand hält sich jedoch in Grenzen, da die zwangsläufig erforderlichen Stellglieder stationär den entsprechenden Einstellorganen zugeordnet werden können. Demgegenüber werden die Einstellmaßnahmen durch Austausch von Teilen oder Einstellmaßnahmen, die keine extrem geringen Maßtoleranzen einhalten müssen, von Hand durchgeführt. Dadurch entfällt hier der Mehraufwand an vorrichtungstechnischen Maßnahmen, der besonders bei der Handhabung auszutauschender Teile einen großen Umfang annehmen würde.By restricting the adjustment measures to be carried out automatically to dimensional settings, the particularly critical adjustment measures which are subject to large tolerances in manual execution are automated. However, the additional expenditure on device technology is limited, since the actuators that are inevitably required can be assigned to the corresponding setting elements in a stationary manner. In contrast, the adjustment measures are carried out by hand by exchanging parts or adjustment measures that do not have to comply with extremely small dimensional tolerances. As a result, there is no additional expenditure on device-related measures, which would take on a large scope, particularly when handling parts to be replaced.

Ergänzend können die manuell vorgenommenen Einstellmaßnahmen sensorisch überwacht werden und ein Anfahren der im Einrichtungsablauf vorgesehenen nächsten Position erst vorgenommen werden, wenn eine Übereinstimmung zwischen Ist- und Sollwert ermittelt wurde.In addition, the manually performed adjustment measures can be monitored by sensors and the next position provided in the set-up sequence can only be approached when a match between the actual and target values has been determined.

Durch diese Weiterbildung lassen sich eventuell noch mögliche Fehler, die z.B. durch einen nicht vorgenommenen Austausch, fehlerhaften Einbau oder den Einbau falscher Maschinenteile entstehen könnten, vermeiden.This further training can possibly also eliminate possible errors, e.g. through an incorrect replacement, incorrect installation or the installation of wrong machine parts.

Bei einem vollständigen Einrichtungsablauf werden folgende Einstellmaßnahmen in folgender Reihenfolge durchgeführt:

  • a) Eingabe der Schneidparameter,
  • b) Ausbauen der Formatplatte und der Auswerfer,
  • c) Wechseln von Schneidtisch und Schneidmessern,

  • h) Justieren des Buchanschlags, Einsetzen und Justieren der Auswerfer,

  • k) Vornehmen der Feineinstellungen.
With a complete set-up procedure, the following setting measures are carried out in the following order:
  • a) input of the cutting parameters,
  • b) removing the format plate and the ejector,
  • c) changing the cutting table and cutting knives,
  • d) setting of side knives, head stop and book stop,

  • k) Make the fine adjustments.

Hierbei handelt es sich um Einstellmaßnahmen, die in der beschriebenen Reihenfolge bei einem Dreischneider der AM Wohlenberg GmbH zu einer Minimierung der Einrichtungszeit geführt haben. Im Zuge dieser Einstellmaßnahmen wird die Buchbreite, die Buchhöhe, der Kopfanschlag, die Preßstempelhöhe und die Preßkraft des Stempels automatisch eingestellt.These are adjustment measures which, in the order described, have minimized the set-up time for a three-knife trimmer from AM Wohlenberg GmbH. In the course of these adjustment measures, the book width, the book height, the head stop, the ram height and the pressing force of the ram are automatically set.

Die erfindungsgemäße Vorrichtung ermöglicht es, die bei der Einrichtung des Dreischneiders erforderlichen Einstellmaßnahmen nicht mehr nur ausschließlich manuell sondern in wichtigen, zeitintensiven Bereichen auch automatisch durchführen zu können. Dabei werden jedoch auch für die manuelle Einstellung die Voraussetzungen geschaffen, diese in optimaler Reihenfolge und bei der günstigsten Position der Maschinenumlaufphasen durchführen zu können.The device according to the invention makes it possible to carry out the adjustment measures required when setting up the three-knife cutter not only exclusively manually but also automatically in important, time-consuming areas. However, the prerequisites are also created for the manual setting in order to be able to carry this out in the optimal order and in the most favorable position of the machine circulation phases.

Über die Stellglieder werden die vom Steuerrechner automatisch einzustellenden Schneidparameter umgestellt, so daß hier kein Eingriff durch die Bedienungsperson erforderlich ist. Die Anzeigevorrichtung ermöglicht es, der Bedienperson die in der jeweils eingenommenen Position des Maschinenumlaufs erforderlichen Einstellmaßnahmen anzuzeigen, so daß hierfür keine gesonderte Bedienungs- oder Einrichtanleitung benutzt werden muß. Durch die Eingabevorrichtung können dem Steuerrechner sowohl die für ein einzurichtendes Buchformat erforderlichen Parameter in vereinfachter Form durch Eingabe der Abmessungen eingegeben und die Beendigung manueller Einstellmaßnahmen quittiert werden.The cutting parameters to be set automatically by the control computer are changed over by the actuators, so that no intervention by the operator is required here. The display device makes it possible for the operator to be shown the adjustment measures required in the position of the machine circulation assumed so that no separate operating or setup instructions have to be used for this. The input device allows the control computer to enter the parameters required for a book format to be set up in a simplified form by entering the dimensions and to acknowledge the completion of manual setting measures.

Die sich aus den Abmessungen der fertigen Buchformate ergebenden Einstellparameter lassen sich durch den Steuerrechner selbst ermitteln, so daß die Fehlermöglichkeit bei einer gesonderten Umrechnung der Abmessungen der Formate in Schneidparameter ausgeschlossen ist.The setting parameters resulting from the dimensions of the finished book formats can be determined by the control computer itself, so that the possibility of errors with a separate conversion of the dimensions of the formats into cutting parameters is excluded.

Die Vorrichtung ermöglicht ferner, daß im Speicher des Steuerrechners die zuvor eingestellten Schneidparameter gespeichert sind und daß das Einrichtungsablaufprogramm einen Vergleichsprogrammteil für einen Vergleich zwischen den eingegebenen Schneidparametern und den zuvor eingestellten Schneidparametern umfaßt. An Hand des Vergleichs werden die anzufahrenden Positionen und die durchzuführenden Einstellmaßnahmen in Abhängigkeit der zuvor eingestellten Schneidparameter vorgenommen.The device further enables the previously set cutting parameters to be stored in the memory of the control computer and for the set-up sequence program to include a comparison program part for a comparison between the entered cutting parameters and the previously set cutting parameters. Based on the comparison, the positions to be approached and the adjustment measures to be carried out are shown in Dependent on the previously set cutting parameters.

Diese Eigenschaft der Vorrichtung ermöglicht es, die Vornahme der Einstellmaßnahmen nur auf diejenigen Einzelmaßnahmen zu beschränken, die für die Umstellung auf ein neues Buchformat erforderlich sind. Weist z.B. ein Folgeauftrag ein ähnliches Format wie der vorangegangene Auftrag auf, so können unter Umständen einige Einstellmaßnahmen entfallen, so daß die Einrichtung des Dreischneiders in wesentlich kürzerer Zeit erfolgen kann, als wenn alle Einstellmaßnahmen vorgenommen werden müßten.This property of the device makes it possible to restrict the adjustment measures to only those individual measures that are required for the changeover to a new book format. For example, If a follow-up order has a format similar to the previous order, some adjustment measures may be omitted, so that the three-cutter can be set up in a much shorter time than if all adjustment measures had to be carried out.

Zusätzlich können die Stellglieder durch Istwertgeber ergänzt sein, die ebenfalls mit dem Steuerrechner verbunden sind. Ein im Speicher des Steuerrechners gespeichertes Einrichtungsablaufprogramm umfaßt dann einen Regelungsprogrammteil zur Durchführung eines Sollwert-Istwert-Vergleichs.Actuators can also be added to the actuators, which are also connected to the control computer. A set-up sequence program stored in the memory of the control computer then comprises a control program part for carrying out a setpoint-actual value comparison.

Diese Weiterbildung hat folgende Vorteile. Zum einen läßt sich eine höhere Genauigkeit der einzustellenden Maße erzielen, da die exakte Position durch die Istwertgeber überprüft wird und es nicht allein auf die lineare Übertragung der den Stellgliedern zugeführten Signale auf die von den Stellorganen durchgeführten Einstellmaßnahmen ankommt. Zum anderen läßt sich auch die Präzision des Stellantriebs in vernünftigen Grenzen halten, da Fertigungsungenauigkeiten und Abnutzung durch Verschleiß in seinen Auswirkungen auf die Maßhaltigkeit durch die Istwertgeber kompensiert werden.This training has the following advantages. On the one hand, a higher accuracy of the dimensions to be set can be achieved, since the exact position is checked by the actual value transmitter and it is not only a matter of the linear transmission of the signals supplied to the actuators to the adjustment measures carried out by the actuators. On the other hand, the precision of the actuator can also be kept within reasonable limits, since inaccuracies in production and wear due to wear are compensated for by the actual value transmitters in terms of their dimensional accuracy.

Vorzugsweise sind die Stellglieder und die zusätzlich vorhandenen Istwertgeber solchen Einstellorganen zugeordnet, die Maßeinstellungen der Übergabestation und der Schneidstation vornehmen.The actuators and the additional actual value transmitters are preferably assigned to such setting members which make the dimensional settings of the transfer station and the cutting station.

Die Automatisierung der diese Maßeinstellungen betreffenden Teile des Dreischneiders bewirkt den größten Anteil an Zeiteinsparung bei den Einrichtungsmaßnahmen. Die Einstellung dieser Organe erforderte nämlich bisher ein Umrechnen der endgültigen Formatabmessungen auf die einzustellenden Schneidparameter und die ständige Kontrolle der Abmessungen bei der Einstellung. Die für die Automatisierung erforderlichen Stellglieder lassen sich relativ leicht in die konstruktive Grundgestaltung eines Dreischneiders integrieren, so daß der zusätzliche vorrichtungstechnische Aufwand und die damit verbundenen Zusatzkosten im Vergleich zu den erzielten Einsparungen durch kürzere Stillstandszeiten gering sind.The automation of the parts of the three-knife trimmer relevant to these dimensional settings results in the greatest amount of time saving in the installation measures. The adjustment of these organs has hitherto required a conversion of the final format dimensions to the cutting parameters to be set and the constant control of the dimensions during the adjustment. The actuators required for automation can be integrated relatively easily into the basic design of a three-knife trimmer, so that the additional outlay in terms of device technology and the associated additional costs are low in comparison to the savings achieved through shorter downtimes.

Eine Weiterbildung sieht vor, daß manuelle Einstellorgane mit Sensoren ausgestattet sind, die mit dem Steuerrechner verbunden sind, und daß das Einrichtungsablaufprogramm einen Vergleichsprogrammteil umfaßt, der ein Anfahren der im Einrichtungsablauf vorgesehenen nächsten Position erst dann zuläßt, wenn eine Übereinstimmung zwischen Ist- und Sollwert ermittelt wird.A further development provides that manual setting devices are equipped with sensors which are connected to the control computer, and that the set-up sequence program comprises a comparison program part which only allows the next position provided in the set-up sequence to be approached when a match between the actual value and the target value is determined becomes.

Die Sensoren könnten z.B. Kodiermarken der Einstellorgane oder der auszutauschenden Teile abtasten, die dann im Steuerrechner im Hinblick auf die richtige Einstellung überwacht werden. Ein nicht vorgenommener Austausch, ein fehlerhafter Einbau oder der Einbau falscher Maschinenteile wird so erkannt und kann korrigiert werden, ehe der Fehler zu Beschädigungen an Teilen des Dreischneiders oder zu einer hohen Ausschußquote bei den zu bearbeitenden Büchern führt.The sensors could e.g. Scan coding marks of the setting elements or the parts to be replaced, which are then monitored in the control computer with regard to the correct setting. A replacement that has not been carried out, a faulty installation or the installation of incorrect machine parts is thus recognized and can be corrected before the fault leads to damage to parts of the three-knife trimmer or to a high reject rate for the books to be processed.

Bei einer praktischen Ausgestaltung der Vorrichtung umfassen die Stellglieder, die im Betrieb des Dreischneiders stark belasteten Einsteilorganen zugeordnet sind, jeweils Stellmotore und Klemmvorrichtungen.In a practical embodiment of the device, the actuators, which are associated with heavily loaded adjusting members during operation of the three-cutter, each comprise servomotors and clamping devices.

Diese Klemmvorrichtungen erfüllen zweierlei Funktionen. Zum einen beseitigen sie das Spiel der Einstellorgane, daß im Schneidbetrieb zu Ungenauigkeiten führen würde, wenn die Haltekräfte ausschließlich von den Stellmotoren übernommen würden. Zum anderen ermöglichen sie, die Stellmotore einfacher zu dimensionieren. Müßten nämlich die beim Transport und Schneiden erforderlichen Haltekräfte von den Stellmotoren aufgebracht werden, so wären hier besonders robuste, teure Ausführungen einzusetzen.These clamping devices have two functions. On the one hand, they eliminate the play of the adjusting elements that would lead to inaccuracies in the cutting operation if the holding forces were only taken over by the servomotors. On the other hand, they allow the servomotors to be dimensioned more easily. If the holding forces required for transport and cutting had to be applied by the servomotors, particularly robust, expensive designs would have to be used here.

Durch die Aufteilung in Stellmotore und Klemmvorrichtungen gelingt es hingegen, den vorrichtungstechnischen Aufwand gering zu halten, da die Stell- und Klemmaufgaben nunmehr von verschiedenen, speziell auf die dabei auftretenden Kräfte abgestimmten Elementen vorgenommen werden können. Somit lassen sich Stellmotore einsetzen, die nur auf die bei der Verstellung auftreten Kräfte bemessen sein müssen, während die im Betrieb aufzunehmenden Gegenkräfte von den Klemmvorrichtungen übernommen werden können.By dividing it into servomotors and clamping devices, on the other hand, it is possible to keep the expenditure on device technology low, since the actuating and clamping tasks can now be carried out by various elements which are specially matched to the forces which occur. This means that servomotors can be used that only have to be dimensioned for the forces that occur during the adjustment, while the counterforces to be absorbed during operation can be taken over by the clamping devices.

Eine zusätzliche Weiterbildung sieht vor, daß das dem im Betrieb des Dreischneiders stark belasteten Einstellorgan der Übergabestation zugeordnete Stellglied außer einem ersten Stellmotor für die Grundeinstellung einen zweiten Stellmotor für eine im laufenden Betrieb durchführbare Feineinstellung umfaßt. Die durch den ersten Stellmotor vorgenommene Grundeinstellung ist im laufenden Betrieb durch die Klemmvorrichtung fixierbar.An additional further development provides that the actuator associated with the setting member of the transfer station, which is heavily loaded during operation of the three-knife cutter, comprises, in addition to a first actuator for the basic setting, a second actuator for fine adjustment that can be carried out during operation. The basic setting made by the first servomotor can be fixed during operation by the clamping device.

Für relativ großhübige Einstellvorgänge wird also weiterhin die Aufteilung in einen Stellmotor und eine Klemmvorrichtung beibehalten. Für eine Feineinstellung ist ein zusätzlicher Stellmotor vorgesehen, der jedoch nur geringfügige Maßhübe ausüben muß. Da dies mit einer entsprechend hohen Untersetzung realisierbar ist, reicht trotz der aufzunehmenden Kräfte hier ebenfalls eine Ausführung geringer Leistung aus.For relatively large-scale adjustment processes, the division into an actuator and a clamping device is therefore retained. An additional servo motor is provided for fine adjustment, but this only has to perform slight measuring strokes. Since this can be achieved with a correspondingly high reduction ratio, a low-power version is also sufficient in spite of the forces to be absorbed.

Die in Fig. 1 gezeigte schematische Darstellung der einzelnen Stationen eines Dreischneiders zeigt eine Zuführstation 10, eine Übergabestation 12, eine Schneidstation 14 und ein Auslageband 52.The schematic illustration of the individual stations of a three-cutter shown in FIG. 1 shows a feed station 10, a transfer station 12, a cutting station 14 and a delivery belt 52.

Gebundene Bücher gelangen von der Zuführstation 10 zur Übergabestation 12, wobei der Transport im Arbeitstakt des Dreischneiders durch Vorschubbürsten 112 vorgenommen wird. In der Übergabestation 12 werden die Bücher in Vorbereitung des anschließenden Schneidvorganges ausgerichtet, so daß sich der Druckspiegel nach dem Schneidvorgang in der gewünschten Position befindet.Bound books go from the feed station 10 to the transfer station 12, the transport being carried out in the work cycle of the three-knife trimmer by feed brushes 112. In the transfer station 12, the books are aligned in preparation for the subsequent cutting process, so that the printing level is in the desired position after the cutting process.

Dazu umfaßt die Übergabestation 12 einen verstellbaren Kopfanschlag 54, einen Buchanschlag 56 und einen Zangenwagen 58. Der Zangenwagen 58, dessen Aufbau aus Fig 4 hervorgeht, besteht aus einem Rückenanschlag 60 und einer Zange 62, die ihrerseits eine Bodenplatte 64 und eine Druckbacke 66 umfaßt. Nach der Ausrichtung der Bücher erfolgt ihr Transport in die Schneidstation 14. Dazu wird der Buchstapel von der Zange 62 erfaßt, leicht angehoben und mittels des Zangenwagens 58 in die Schneidstation 14 verbracht.For this purpose, the transfer station 12 comprises an adjustable head stop 54, a book stop 56 and a tong carriage 58. The tong carriage 58, the construction of which can be seen in FIG. 4, consists of a back stop 60 and a tong 62, which in turn comprises a base plate 64 and a pressure jaw 66. After the books have been aligned, they are transported to the cutting station 14. For this purpose, the book stack is gripped by the tongs 62, slightly raised and brought into the cutting station 14 by means of the tongs carriage 58.

Die Schneidstation 14 umfaßt eine Schneidplatte 68 mit Schneidleisten, eine Fixiervorrichtung 70 sowie eine Schneidvorrichtung 72. Die Fixiervorrichtung 70 dient dazu, den Buchstapel während des Schneidvorganges auf der Schneidplatte 68 zu fixieren, damit der Stapel als Ganzes oder einzelne Seiten nicht verrutschen. Das Fixieren erfolgt mittels einer an einer Formatplatte 74, angebrachten Zurichtung 76 die unmittelbar auf den Buchstapel drückt. Die Formatplatte 74 ist an einem Formatplattenhalter 78 befestigt und dieser ist wiederum in der Höhe durch einen Preßstempel 80 verfahrbar. Nach dem Aufsetzen der Zurichtung 76 auf den Buchstapel kann durch Druckerhöhung des Preßstempels 80 auch die erforderliche Preßkraft aufgebracht werden.The cutting station 14 comprises a cutting plate 68 with cutting strips, a fixing device 70 and a cutting device 72. The fixing device 70 serves to fix the stack of books on the cutting plate 68 during the cutting process so that the stack as a whole or individual pages does not slip. Fixing takes place by means of a dressing 76, which is attached to a format plate 74 and presses directly onto the book stack. The format plate 74 is fastened to a format plate holder 78 and this can in turn be moved in height by a press ram 80. After the dressing 76 has been placed on the stack of books, the required pressing force can also be applied by increasing the pressure of the press ram 80.

Die zum Beschneiden des Buchstapels auf das endgültige Format dienende Schneidvorrichtung 72 umfaßt drei Messer, nämlich zwei Seitenmesser 82, 84 und ein Vordermesser 86. Die Seitenmesser 82, 84 und das Vordermesser 86 befinden sich jeweils in einem Messerhalter 88, 90, 92, wobei die Seitenmesserhalter 88 und 90, wie es insbesondere die Figuren 2 und 3 zeigen, ihrerseits auf einem Seitenmesserbalken 94 befestigt und geführt sind. Zwei Messerantriebe besorgen die zum Schneiden erforderliche Bewegung der Messer 82, 84, 86. In Fig 1 sind in der Schneidstation 14 die sich durch die Anordnung der Messer 82, 84, 86 ergebenden Schnittlinien gestrichelt dargestellt.The cutting device 72 used to cut the stack of books to the final format comprises three knives, namely two side knives 82, 84 and a front knife 86. The side knives 82, 84 and the front knife 86 are each located in a knife holder 88, 90, 92, the Side knife holders 88 and 90, as shown in particular in FIGS. 2 and 3, are in turn fastened and guided on a side knife bar 94. Two knife drives provide the movement of the knives 82, 84, 86 required for cutting. In FIG. 1, the cutting lines resulting from the arrangement of the knives 82, 84, 86 are shown in dashed lines in the cutting station 14.

Nach dem Schneidvorgang werden die auf das endgültige Format beschnittenen Bücher durch Auswerfer 16 erfaßt und auf das Auslageband 52 transportiert.After the cutting process, the books cut to the final format are gripped by ejectors 16 and transported to the delivery belt 52.

Von den drei Messern in der Schneidstation 14 ist das Vordermesser 86 nicht verstellbar, jedoch sind die beiden Seitenmesser 82, 84 durch ein Stellglied 24 in der Breite verstellbar. Das Stellglied 24 ist in den Fig. 2 und 3 veranschaulicht. Es umfaßt einen Stellmotor 44, der eine Gewindespindel 96 antreibt, die beide Seitenmesserhalter 88, 90 durchdringt. Die auf der Gewindespindel 96 befindlichen Gewinde sind für die beiden Seitenmesserhalter 88, 90 gegensinnig ausgebildet, so daß die Seitenmesserhalter 88, 90 bei der einen Drehrichtung auseinandergehen, während sie in der anderen Drehrichtung zusammenkommen.The front knife 86 cannot be adjusted from the three knives in the cutting station 14, but the width of the two side knives 82, 84 can be adjusted by an actuator 24. The actuator 24 is illustrated in FIGS. 2 and 3. It includes an actuator 44 which drives a threaded spindle 96 which penetrates both side knife holders 88, 90. The threads on the threaded spindle 96 are formed in opposite directions for the two side knife holders 88, 90, so that the side knife holders 88, 90 diverge in one direction of rotation while they come together in the other direction of rotation.

An der dem Stellmotor 44 gegenüberliegenden Seite der Gewindespindel 96 befindet sich ein Istwertgeber 38, der die durchgeführten Umdrehungen der Gewindespindel 96 erfaßt und dem Steuerrechner 18 mitteilt. Das Stellglied 24 für die Seitenmesser 82, 84 umfaßt außerdem eine Klemmvorrichtung 48, die die Seitenmesserhalter 88, 90 auf dem Seitenmesserbalken 94 im normalen Betrieb festklemmt und nur während der Einstellphase durch den Stellmotor 44 löst. Der Aufbau dieser Klemmvorrichtung ergibt sich aus Fig. 3, und zwar besitzt die Klemmvorrichtung 48 ein Tellerfederpaket 98, auf einem Gewindebolzen 100, das die Klemmbacken 102 im Normalfall zusammendrückt, und eine hydraulische Spreizvorrichtung 104, die die Klemmbacken 102 zur Ermöglichung einer Verstellung durch Spreizung löst. Durch Einstellung des Abstandes der Seitenmesser 82 und 84 wird die Höhe des Buchformates festgelegt.On the side of the threaded spindle 96 opposite the servomotor 44 there is an actual value transmitter 38 which detects the revolutions of the threaded spindle 96 carried out and communicates it to the control computer 18. The actuator 24 for the side knives 82, 84 also includes a clamping device 48 which clamps the side knife holder 88, 90 on the side knife bar 94 in normal operation and only releases during the adjustment phase by the servomotor 44. The structure of this clamping device results from Fig. 3, namely the clamping device 48 has a plate spring assembly 98, on a threaded bolt 100, which normally compresses the clamping jaws 102, and a hydraulic spreading device 104, which enables the clamping jaws 102 to be adjusted by spreading solves. The height of the book format is determined by adjusting the distance between the side knives 82 and 84.

Die Buchbreite sowie die Lage des Druckspiegels wird durch Einstellungen der Übergabestation 12 bestimmt. Der dort vorhandene verstellbarer Kopfanschlag 54, der die vertikale Lage des Druckspiegels vorgibt, ist ebenfalls durch ein Stellglied 22 einstellbar. Dieses Stellglied 22 umfaßt einen Stellmotor 106 der über eine Gewindespindel 108 den Kopfanschlag 54 horizontal verschieben kann. Mit dem Stellmotor 106 ist ein Istwertgeber 36 zur Rückmeldung der eingestellten Lage des Kopfanschlags 54 an den Steuerrechner 18 verbunden.The book width and the position of the printing surface is determined by the settings of the transfer station 12. The adjustable head stop 54 present there, which specifies the vertical position of the pressure mirror, is also adjustable by an actuator 22. This actuator 22 comprises an actuator 106 which can move the head stop 54 horizontally via a threaded spindle 108. An actual value transmitter 36 is connected to the servomotor 106 for feedback of the set position of the head stop 54 to the control computer 18.

Die Einstellung der Buchbreite und der horizontalen Lage des Druckspiegels besorgt der Rükkenanschlag 60 des Zangenwagens 58. Dazu ist die Einstellung des Zangenwagens 58 mit Hilfe eines Stellgliedes 20 automatisch möglich. Der Zangenwagen 58 verfügt außerdem über einen Istwertgeber 34, der die Grundstellung dem Steuerrechner 18 übermittelt. Das Stellglied 20 umfaßt einen Stellmotor 42 und eine Klemmvorrichtung 46, die ähnlich der Klemmvorrichtung 48 aufgebaut ist. Die Klemmvorrichtung 46 sorgt dafür, daß das durch das Stellorgan verursachte Spiel beseitigt wird und die bei den Transportbewegungen des Zangenwagens 58 auftretenden dynamischen Kräfte nicht den Stellmotor 42 belasten.The back stop 60 of the tong carriage 58 takes care of the adjustment of the book width and the horizontal position of the pressure mirror. For this purpose, the tong carriage 58 can be automatically adjusted using an actuator 20. The tong carriage 58 also has an actual value transmitter 34 which transmits the basic position to the control computer 18. The actuator 20 comprises an actuator 42 and a clamping device 46, which is constructed similarly to the clamping device 48. The clamping device 46 ensures that the play caused by the actuator is eliminated and the dynamic forces occurring during the transport movements of the tong carriage 58 do not burden the servomotor 42.

Mit Hilfe der Zange 62 des Zangenwagens 58 wird der in der Übergabestation 12 befindliche Buchstapel erfaßt und beim Transport in die Schneidstation 14 angehoben, so daß einmal keine Schleifspuren auf der Unterseite auftreten können und zum anderen die in der Übergabestation 12 vorgenommene Ausrichtung des Buchstapels auf dem Wege in die Schneidstation 14 erhalten bleibt. Der für die Ausrichtung des Buchstapels ebenfalls vorhandene Buchanschlag 56 wird beim Transport hochgeschwenkt.With the aid of the pliers 62 of the pliers carriage 58, the stack of books located in the transfer station 12 is grasped and raised during transport into the cutting station 14, so that no traces of grinding can occur on the underside and, on the other hand, the alignment of the book stack carried out in the transfer station 12 on the Paths in the cutting station 14 is preserved. The book stop 56, which is also available for the alignment of the book stack, is pivoted up during transport.

Um berücksichtigen zu können, daß der in Richtung auf das Vordermesser 86 bewegte und im gewünschten Abstand davon gestoppte Zangenwagen 58 aufgrund seiner Massenträgheit noch eine geringfügige weitere Auslenkung vollführt, ist auch noch im laufenden Betrieb eine Einstellung des Rückenanschlags 60 vorgesehen. Zu diesem Zweck ist neben dem ersten Stellglied 20 mit dem Stellmotor 42 für die Grundeinstellung ein zweites Stellglied 114 mit einem zweiten Stellmotor 50 für eine auch im laufenden Betrieb durchführbare Feineinstellung vorhanden. Dieser zweite Stellmotor 50 ist durch einen Istwertgeber 110 ergänzt, der dem Steuerrechner 18 die Position übermittelt.In order to be able to take into account that the pliers carriage 58 moved in the direction of the front knife 86 and stopped at the desired distance therefrom performs a slight further deflection due to its inertia, an adjustment of the back stop 60 is also provided during operation. For this purpose, in addition to the first actuator 20 with the servomotor 42 for the basic setting, there is a second actuator 114 with a second servomotor 50 for fine adjustment that can also be carried out during operation. This second servomotor 50 is supplemented by an actual value transmitter 110, which transmits the position to the control computer 18.

Auch der Kopfanschlag 54 ist im Betrieb verstellbar. Da hier jedoch die Haltekräfte sehr gering sind, erübrigt sich eine Ausführung mit einer Klemmvorrichtung. Vielmehr können die Kräfte von dem einzigen Stellmotor 106 aufgebracht werden.The head stop 54 is also adjustable during operation. However, since the holding forces are very low here, an embodiment with a clamping device is not necessary. Rather, the forces can be applied by the single servomotor 106.

Der Preßstempel 80 zum Verfahren der Formatplatte 74 bildet schließlich ein Stellglied 26 wobei die Hubhöhe und der Preßdruck durch einen Istwertgeber 40 an den Steuerrechner 18 übermittelbar sind.The press ram 80 for moving the format plate 74 finally forms an actuator 26, the lifting height and the pressing pressure being able to be transmitted to the control computer 18 by an actual value transmitter 40.

Fig. 5 zeigt ein Blockschaltbild der Steuerung des Dreischneiders. Ein Steuerrechner 18 umfaßt einen Speicher 32 für Steuer- und Vergleichsprogramme sowie zur Speicherung von Daten der Schneidparameter. Der Steuerrechner ist mit Stellgliedern 20, 22, 24, 26, 114 und Istwertgebern 34, 36, 38, 40, 110 verbunden und ermöglicht so die Einstellung von Schneidparametern über Einstellorgane im Sinne einer Istwert-Sollwert-Regelung. Außerdem ist mit dem Steuerrechner 18 eine Anzeigevorrichtung 28 und eine Eingabevorrichtung 30 verbunden, die die Eingabe von Schneidparametern und die die Anweisung zur Ausführung von Einstellmaßnahmen im Dialog ermöglicht.Fig. 5 shows a block diagram of the control of the three-cutter. A control computer 18 includes a memory 32 for control and comparison programs and for storing data of the cutting parameters. The control computer is connected to actuators 20, 22, 24, 26, 114 and actual value transmitters 34, 36, 38, 40, 110 and thus enables the setting of cutting parameters via setting members in the sense of an actual value setpoint control.
