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 nach dem Oberbegriff des Anspruchs 1 bzw des Anspruchs 7.The invention relates to a method and an apparatus for setting up a Triple cutter according to the preamble of claim 1 or 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 one used in the bookbinding industry Cutting device, the three cutting knives, namely includes a front knife and two side knives. One such three-knife trimmers are via a feed station Books fed that are already bound on the back. The job of the three-tailor is to get the books on the sides and on the front edge in one operation cut 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.Because the local arrangements of knives and others Cutting parameters according to the format of the to be cut Books and the cutting quality desired by the client need to straighten, it is necessary to use the three-knife trimmer to set up before executing any order.

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 done by the operator performed manually, which takes long set-up times in which the three-knife trimmer did not could 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 have the appropriate Positions within the machine circulation phases To start typing operation, it depends on the skill and operator experience depended on the drive switch off in time that after the occurrence of the drive overrun time just delayed standstill the desired position has been reached. Became this position namely exceeded, was a new attempt required 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 3⊘ Minuten.Lately there has been a significant increase in printed matter and books in small editions. This causes it to become more common in practice Orders with different book formats have to be processed. The set-up times are therefore of great importance to because the corresponding time-consuming work in the Compared to the usage time of the triple cutter larger become. A normal setting of the cutting parameters of Hand takes up to 3⊘ 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 when changing the book format, the corresponding ones Facilities are required, more so suffers from the profitability of the operation of the Triple cutter.

Aus der gattungsbildenden JP-A-63062696 ist ein Dreischneider bekannt, der eine rechnergesteuerte Einrichtung seiner Zuführstation, Übergabestation und Schneidstation vorsieht. Dazu verfügt der Dreischneider über einen Rechner mit einer Ein- und Ausgabevorrichtung, über die Schneidparameter eingegeben und angezeigt werden können. Der Rechner ist mit motorisch betätigbaren Stellgliedern verbunden, die entsprechend den eingegebenen Schneidparametern Einrichtemaßnahmen vornehmen. Durch Sensoren an den einzurichtenden Teilen des Dreischneiders werden Istwerte der Schneidparameter ermittelt und an den Rechner geleitet. Durch Soll-Istwert-Vergleich der Schneidparameter können die Stellglieder präzise betätigt werden. A triple cutter is known from JP-A-63062696 known of a computerized facility its feed station, transfer station and cutting station provides. The three-knife trimmer has a computer for this with an input and output device via which Cutting parameters can be entered and displayed. The computer is equipped with actuators that can be actuated by motor connected according to the entered cutting parameters Carry out setup measures. Through sensors on The parts of the three-knife trimmer to be set up become actual values the cutting parameter is determined and sent to the computer headed. By comparing the target and actual values of the cutting parameters the actuators can be operated precisely.

Der Erfindung liegt die Aufgabe zugrunde, das eingangsgenannte Verfahren und die eingangsgenannte Vorrichtung dahingehend zu verbessern, daß die Einstellung der Schneidparameter schneller und präziser vorgenommen werden kann.The invention has for its object the above Method and the device mentioned to improve in that the setting of the cutting parameters more quickly and can be made 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 task is carried out in a method according to the generic term of claim 1 by the in the characterizing part Features specified in this claim, and in a device according to the preamble of claim 7 by the in the characterizing part of the specified features solved.

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 be carried out automatically. It is very helpful making sure that the corresponding positions within a or several machine circulation phases be, so that the appropriate adjustment measures quickly can be carried out.

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 to be carried out queue. This way even inexperienced personnel possible to set up the triple cutter within to perform in a very short time. In particular, it needs Operator not the optimal by own experiments Order and find the optimal positions in to carry out the appropriate adjustment work are. In addition, through the predetermined program flow ensures that damage due to collisions, the wrong order of adjustment measures could occur can be avoided.

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 to set up the three-knife trimmer is entered in a dialog with the control computer become. The scope of the positions to be approached and the Adjustment measures to be carried out will depend 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 individual cutting parameters are accidentally omitted and then in the later cutting operation to a high scrap rate could lead. By taking the adjustment measures depending on previously set Cutting time can be set for follow-up orders with similar formats sometimes shorten considerably, since not all cutting parameters are always changed must and so part of the adjustment measures are omitted can.

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 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 dimensions you want with a high precision and thus also a high cutting quality can be achieved. Reading or calculation errors, as in the previous manual setup of three-knife trimmers were not always avoidable, 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 is a Distribution of the adjustment measures in computer-controlled on the one hand to be carried out automatically and on the other hand adjustment measures to be carried out manually. The computer-controlled adjustment measures to be carried out automatically concern the dimension setting of the transfer station and the cutting station and those to be carried out manually Adjustment measures concern the exchange 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 automatic ones Adjustment measures on dimensional settings are the special critical and with large tolerances at one manual execution automated adjustment measures. The additional device expenditure persists however within limits, as the inevitably required Actuators stationary the corresponding setting elements can be assigned. In contrast, the adjustment measures by exchanging parts or adjustment measures, that do not adhere to extremely small dimensional tolerances must be done by hand. This eliminates here the additional expenditure on device-technical measures, the one to be exchanged especially when handling Parts would take on a large scale.

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 manual adjustment measures can be carried out be monitored by sensors and a start of the the next position provided in the setup process be made if there is a match between Actual and setpoint was 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 may still be possible Errors that e.g. by a not made Exchange, incorrect installation or incorrect installation Avoid 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,
  • i) Einstellen der Formatplatte auf Stapelhöhe,
  • j) Einstellen der Zuführstation und
  • 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,
  • e) adjusting the book width,

  • 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 that are carried out in the described sequence for a three-knife trimmer from AM Wohlenberg GmbH to minimize the set-up time have led. 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 stamp is 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 the setting measures required to set up the three-knife trimmer no longer just manual but also automatically in important, time-consuming areas to be able to perform. However, also the prerequisites for manual adjustment have been created, these in optimal order and at the cheapest Perform position of machine cycle phases to can.

    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 control computer automatically uses the actuators changed cutting parameters to be set, see above that no intervention by the operator is required here is. The display device enables the Operator in the position assumed in each case necessary adjustment measures of the machine circulation display, so that no separate operating or Setup instructions must be used. Through the input device can the control computer both for a parameter required to set up the book format Entered in a simplified form by entering the dimensions and the termination of manual adjustment measures be acknowledged.

    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 resulting from the dimensions of the finished book formats resulting setting parameters can be controlled by the control computer determine yourself, so the possibility of error with a separate conversion of the dimensions of the formats is excluded in cutting parameters.

    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 also enables that in the memory of the Control computer the previously set cutting parameters are stored and that the setup sequence program a comparison program part for a comparison between the entered cutting parameters and the previously set ones Includes cutting parameters. Based on the comparison the positions to be approached and those to be carried out Adjustment measures depending on the previously set Cutting parameters made.

    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 enables it to be made the adjustment measures only apply to those individual measures to limit those for switching to a new book format are required. For example, a follow-up order a format similar to the previous order under certain circumstances, some adjustment measures omitted, so that the establishment of the three-cutter can be done in a much shorter time than if all adjustment measures would have 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.In addition, the actuators can be controlled by actual value transmitters be supplemented, which is also connected to the control computer are. A stored in the memory of the control computer Setup sequence program then comprises a control program part to carry 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. For one, lets a higher accuracy of the dimensions to be set achieve, because the exact position by the actual value transmitter is checked and it is not just for linear transmission of the signals fed to the actuators to the Adjustment measures carried out by the actuators arrives. On the other hand, the precision of the Keep the actuator within reasonable limits because of manufacturing inaccuracies and wear and tear in its effects on the dimensional accuracy by the actual value transmitter be compensated.

    Vorzugsweise sind die Stellglieder und die zusätzlich vorhandenen Istwertgeber solchen Einstellorganen zugeordnet, die Maßeinstellungen der Übergabestation und der Schneidstation vornehmen. Preferably, the actuators and the additional existing actual value transmitters assigned to such setting elements, the dimensional settings of the transfer station and the Carry out 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 these dimensional settings Parts of the triple cutter make up the largest share saving time in the furnishing measures. The setting these organs have so far required one Convert the final format dimensions to those to be set Cutting parameters and constant control the dimensions when setting. The one for automation required actuators can be relative easy in the basic design of a three-cutter integrate so that the additional device technology Effort and the associated additional costs compared to the savings achieved through shorter downtimes are low.

    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 elements are equipped with sensors that work with the control computer are connected, and that the facility flow program includes a comparison program part that starts up the the next position provided in the setup process then allows if there is a match between the actual and Setpoint is determined.

    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. Coding marks of the setting elements or the parts to be replaced, which are then in the Control computer with regard to the correct setting be monitored. An exchange not made, a incorrect installation or installation of wrong machine parts is recognized and can be corrected before the Failure to damage parts of the triple cutter or a high reject rate among those to be processed Books.

    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 include the actuators that operate the triple cutter heavily loaded organs are assigned, each 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. Firstly, they eliminate the play of the adjusting elements, that in the cutting operation would lead to inaccuracies, if the holding forces come exclusively from the servomotors would be taken over. On the other hand, they enable that Servomotors easier to dimension. Should be the holding forces required during transport and cutting would be applied by the servomotors use particularly robust, expensive versions 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 into servomotors and clamping devices On the other hand, it succeeds in the device engineering effort to be kept low, since the setting and clamping tasks now from different ones, specifically to those that occur Forces coordinated elements are made can. This means that servomotors can only be used to the forces occurring during the adjustment must be while the counter forces to be absorbed in the operation be taken over by the clamping devices can.

    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 training provides that the im Operation of the three-knife trimmer heavily loaded actuator assigned to the transfer station except one first servomotor for the basic setting a second Actuator for a feasible during operation Includes fine adjustment. By the first servomotor The basic setting made is in ongoing operation fixable 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 settings, it will continue to be the division into a servomotor and a clamping device maintained. For a fine adjustment is a additional servomotor provided, but only have to exercise minor measuring strokes. Since this is with a correspondingly high reduction is feasible in spite of the forces to be absorbed, also an execution here low performance.

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

    Gebundene Bücher gelangen von der Zuführstation 1⊘ 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 reach the feed station 1⊘ Transfer station 12, the transport in the work cycle of the three-knife trimmer by feed brushes 112 becomes. The books are being prepared in the transfer station 12 the subsequent cutting process, so that the pressure level after the cutting process is in the desired position.

    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 6⊘ 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 one Head stop 54, a book stop 56 and a tong carriage 58. The tong carriage 58, the construction of which is shown in FIG. 4 emerges, consists of a back stop 6⊘ and one Pliers 62, which in turn have a base plate 64 and a Compression jaw 66 includes. After aligning the books they are transported to the cutting station 14 the book stack gripped by the pliers 62, slightly raised and into the cutting station 14 by means of the tong carriage 58 spent.

    Die Schneidstation 14 umfaßt eine Schneidplatte 68 mit Schneidleisten, eine Fixiervorrichtung 7⊘ sowie eine Schneidvorrichtung 72. Die Fixiervorrichtung 7⊘ 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 8⊘ verfahrbar. Nach dem Aufsetzen der Zurichtung 76 auf den Buchstapel kann durch Druckerhöhung des Preßstempels 8⊘ auch die erforderliche Preßkraft aufgebracht werden.The cutting station 14 also includes a cutting plate 68 Cutting strips, a fixing device 7⊘ and one Cutting device 72. The fixing device 7⊘ serves to the stack of books during the cutting process on the Fix cutting plate 68 so that the stack as a whole or individual pages do not slip. The fixation takes place by means of an attached to a format plate 74 Dressing 76 the immediately on the book stack presses. The format plate 74 is on a format plate holder 78 attached and this is again in height can be moved by a press ram 8⊘. After touchdown The dressing 76 on the stack of books can be done by increasing the pressure of the ram 8⊘ also the required pressing force be applied.

    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, 9⊘, 92, wobei die Seitenmesserhalter 88 und 9⊘, 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 one for trimming the book stack to the final one Format cutting device 72 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 located each in a knife holder 88, 9⊘, 92, the Side knife holder 88 and 9⊘, as is particularly the case Figures 2 and 3 show, in turn, on a side knife bar 94 are attached and guided. Two knife drives provide the movement required for cutting the knife 82, 84, 86. In Fig. 1 are in the cutting station 14 which are distinguished by the arrangement of the knives 82, 84, 86 resulting cut lines shown in dashed lines.

    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 final Format cropped books captured by ejector 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, 9⊘ durchdringt. Die auf der Gewindespindel 96 befindlichen Gewinde sind für die beiden Seitenmesserhalter 88, 9⊘ gegensinnig ausgebildet, so daß die Seitenmesserhalter 88, 9⊘ bei der einen Drehrichtung auseinandergehen, während sie in der anderen Drehrichtung zusammenkommen.That is of the three knives in the cutting station 14 Front knife 86 is not adjustable, but the two are Side knife 82, 84 by an actuator 24 in width adjustable. The actuator 24 is shown in FIGS. 2 and 3 illustrated. It includes an actuator 44, the one Threaded spindle 96 drives both side knife holders 88, 9⊘ penetrates. Those located on the threaded spindle 96 Threads are for the two side knife holders 88, 9⊘ formed in opposite directions, so that the side knife holder 88, 9⊘ diverge in one direction of rotation, while they come together in the other direction.

    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, 9⊘ 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 1⊘⊘, das die Klemmbacken 1⊘2 im Normalfall zusammendrückt, und eine hydraulische Spreizvorrichtung 1⊘4, die die Klemmbacken 1⊘2 zur Ermöglichung einer Verstellung durch Spreizung löst. Durch Einstellung des Abstandes der Seitenmesser 82 und 84 wird die Höhe des Buchformates festgelegt.On the opposite side of the actuator 44 Threaded spindle 96 is an actual value transmitter 38, the the revolutions of the threaded spindle 96 detected and communicated to the control computer 18. The actuator 24 for the side knives 82, 84 also includes one Clamping device 48, the side knife holder 88, 9⊘ clamped on the side knife bar 94 in normal operation and only during the adjustment phase by the servomotor 44 releases. The structure of this clamping device results 3 from the clamping device 48 a plate spring assembly 98, on a threaded bolt 1⊘⊘, the the jaws 1⊘2 normally compress, and a hydraulic spreader 1⊘4 that the jaws 1⊘2 to enable adjustment by Spreading triggers. By adjusting the distance between the side knives 82 and 84 determine the height of the book format.

    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 1⊘6 der über eine Gewindespindel 1⊘8 den Kopfanschlag 54 horizontal verschieben kann. Mit dem Stellmotor 1⊘6 ist ein Istwertgeber 36 zur Rückmeldung der eingestellten Lage des Kopfanschlags 54 an den Steuerrechner 18 verbunden.The book width as well as the position of the print mirror will determined by settings of the transfer station 12. The there adjustable head stop 54 which the vertical position of the pressure mirror is also adjustable by an actuator 22. This actuator 22nd includes an actuator 1⊘6 which has a threaded spindle 1⊘8 can move the head stop 54 horizontally. With Actuator 1⊘6 is an actual value transmitter 36 for feedback the set position of the head stop 54 to the Control computer 18 connected.

    Die Einstellung der Buchbreite und der horizontalen Lage des Druckspiegels besorgt der Rückenanschlag 6⊘ des Zangenwagens 58. Dazu ist die Einstellung des Zangenwagens 58 mit Hilfe eines Stellgliedes 2⊘ automatisch möglich. Der Zangenwagen 58 verfügt außerdem über einen Istwertgeber 34, der die Grundstellung dem Steuerrechner 18 übermittelt. Das Stellglied 2⊘ 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 setting of the book width and the horizontal position of the pressure level is provided by the back stop 6⊘ of the gun carriage 58. To do this is the setting of the tong carriage 58 automatically possible with the help of an actuator 2⊘. The tong carriage 58 also has an actual value transmitter 34, which transmits the basic position to the control computer 18. The actuator 2⊘ includes an actuator 42 and a clamp 46 which is similar to the clamp 48 is constructed. The clamping device 46 provides for the game caused by the actuator is eliminated and the transport movements of the Zangenwagens 58 dynamic forces not the Load 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 help of the pliers 62 of the pliers 58 the in the transfer station 12 located book stack and raised during transport to the cutting station 14 so that once there are no traces of grinding on the underside can and on the other hand that made in the transfer station 12 Alignment of the book stack on the way to the Cutting station 14 is retained. The one for registration of the book stack also existing book stop 56 is swung 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 6⊘ vorgesehen. Zu diesem Zweck ist neben dem ersten Stellglied 2⊘ mit dem Stellmotor 42 für die Grundeinstellung ein zweites Stellglied 114 mit einem zweiten Stellmotor 5⊘ für eine auch im laufenden Betrieb durchführbare Feineinstellung vorhanden. Dieser zweite Stellmotor 5⊘ ist durch einen Istwertgeber 11⊘ ergänzt, der dem Steuerrechner 18 die Position übermittelt.In order to be able to take into account that the towards the Front knife 86 moved and at the desired distance from it stopped pliers 58 due to its inertia a slight further deflection is carried out a setting of the Back stop 6⊘ provided. For this purpose is next to the first actuator 2⊘ with the actuator 42 for the Basic setting a second actuator 114 with a second servomotor 5⊘ for one even during operation feasible fine adjustment available. This second Actuator 5⊘ is supplemented by an actual value transmitter 11⊘, 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 1⊘6 aufgebracht werden.The head stop 54 is also adjustable during operation. There here, however, the holding forces are very low a version with a clamping device. Much more the forces from the single servomotor 1motor6 can be applied become.

    Der Preßstempel 8⊘ zum Verfahren der Formatplatte 74 bildet schließlich ein Stellglied 26 wobei die Hubhöhe und der Preßdruck durch einen Istwertgeber 4⊘ an den Steuerrechner 18 übermittelbar sind. The press ram 8⊘ for moving the format plate 74th finally forms an actuator 26 with the lifting height and the pressing pressure by an actual value transmitter 4⊘ to the Control computers 18 are communicable.

    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 2⊘, 22, 24, 26, 114 und Istwertgebern 34, 36, 38, 4⊘, 11⊘ verbunden und ermöglicht so die Einstellung von Schneidparametern über Einstellorgane im Sinne einer Istwert-Sollwert-Regelung.
