Description

Die Erfindung betrifft eine Vorrichtung zur Synchronisierung der Zuführung von Bogen mit dem Takt einer buchbindenden Weiterverarbeitungsmaschine, insbesondere Fadensiegelmaschine, der eine Bogen-Übergabevorrichtung vorgelagert ist.The invention relates to a device for synchronization the feeding of sheets with the beat of a bookbinding Processing machine, in particular thread sealing machine, which is preceded by a sheet transfer device.

Eine solche Synchronisationsvorrichtung für die Übergabe von Bogen aus Papier, Karton oder dergleichen an Maschinen zur buchbindenden Weiterverarbeitung wird immer dann benötigt, wenn die Bogenzuführung auf den Takt dieser Weiterverarbeitungsmaschine abgestimmt werden muß. Wird an eine Falzmaschine oder einen Falzbogenanleger ein Fadensiegelmaschine angeschlossen, das jeden Falzbogen während seines Durchlaufes mit der jeweils notwendigen Anzahl Fadenklammern versieht, ist eine Synchronisierung der Bogen in den Takt der Fadensiegelmaschine notwendig. Such a synchronization device for the transfer of Sheets of paper, cardboard or the like on machines for bookbinding further processing is always required if the sheet feeder is on the beat of this finishing machine must be coordinated. Will be on a folding machine or a folding sheet feeder a thread sealing machine connected to each folder during its passage with the necessary number of thread clips, is a synchronization of the bow to the beat of the Thread sealing machine necessary.

Beim Einbringen der Fadenklammern in einen Bogen ist es notwendig, einen konstanten Abstand von der Vorderkante des Falzbogens zu den Fadenklammern zu gewährleisten. Von der Falzmaschine oder einem Falzbogenanleger kommen die Falzbogen unregelmäßig, was ohne Synchronisation zur Folge hätte, daß der Abstand der Fadenklammern zur Bogenvorderkante schwankt. Deshalb ist es notwendig, daß die Falzbogen, bevor sie in den Siegelbereich des Fadensiegelmaschine kommen, auf Fadenklammertakt synchronisiert werden.When inserting the thread clips into an arch, it is necessary a constant distance from the front edge of the Ensure the folding sheet to the thread clips. Of the The folding sheets or a folding sheet feeder come with the folding sheets irregular, which would result in no synchronization, that the distance of the thread clips to the leading edge of the sheet fluctuates. Therefore it is necessary that the folding sheet before they come into the sealing area of the thread sealing machine Thread clip clock can be synchronized.

Das Synchronisieren der Bogen wird bei einer aus der DD 122 359 bekannten Einrichtung dadurch gelöst, daß mittels einer umlaufenden Kette, deren Anschläge in die Bogenebene eines Zuführtisches gesteuert werden, die mit einer höheren Geschwindigkeit zugeführten Bogen sich an den mit einer geringeren Geschwindigkeit bewegten Anschlägen ausrichten und deren Taktgeschwindigkeit annehmen. Diese Art der Synchronisation bedingt einen sehr komplizierten Zuführ- und Ausrichtetisch sowie eine sehr aufwendige Takteinrichtung.The synchronization of the bows is done at one of the DD 122 359 known device solved in that by means of a revolving chain, the stops in the arch plane of a feed table can be controlled with a higher Speed fed sheets adhere to those with a lower Align the speed of the moving stops and assume their clock speed. This kind of synchronization requires a very complicated feed and alignment table as well as a very complex clock mechanism.

Trotz dieser komplizierten und aufwendigen Einrichtung bleibt das Problem des Widerspruches zwischen kontinuierlicher und lagegenauer Ausrichtung sowie Taktung und damit Verzögerung der Bogen. Die in die Bogenebene gesteuerten Anschläge erzeugen immer eine Kraftkomponente, die bestrebt ist, die Bogen vom Ausrichtelineal des Zuführtisches zu entfernen.Despite this complicated and expensive setup remains the problem of contradiction between continuous and precise alignment and timing and thus Delay the bow. The steered into the arch plane Stops always create a force component that strives is to remove the sheets from the feed table alignment ruler.

Aus der EP-A-0 244 484 ist eine Vorrichtung zur Synchronisierung der Zuführung von flächigen Materialien mit dem Takt, der für die weitere Bearbeitung notwendig ist, bekannt, bei der die Übergabevorrichtung durch zwei übereinandergestellte Transportwalzen gebildet ist. Die Vorrichtung weist weiterhin eine variable Transportgeschwindigkeit auf. From EP-A-0 244 484 is a device for synchronization the feeding of flat materials with the Clock that is necessary for further processing is known, in which the transfer device by two superimposed Transport rollers is formed. The device still has a variable transport speed.

Ein gegenüber dem Takt der Weiterverarbeitungsmaschine nacheilender Materialbogen wird vorübergehend beschleunigt, ein voreilender Materialbogen verzögert. Ferner ist aus der EP-A-0 615 941 eine Registriervorrichtung für Papierbogen bekannt, bei der die Papierbogen durch seitliche Beschleunigung bzw. Abbremsung registriert werden.A lagging behind the clock of the processing machine Material sheet is temporarily accelerated leading material sheet delayed. Furthermore, from the EP-A-0 615 941 a registration device for paper sheets known in which the paper sheet by lateral acceleration or braking are registered.

Der Erfindung liegt die Aufgabe zugrunde, die Synchronisierung der Bogen zu vereinfachen und unabhängig von der Ausbildung der die Bogen heranführenden Maschine zu machen.The invention has for its object the synchronization to simplify the bow and regardless of training of making the sheet moving machine.

Diese Aufgabe wird durch eine Vorrichtung zur Synchronisierung der Zuführung von Bogen mit dem Takt einer buchbindenden Weiterverarbeitungsmaschine mit den Merkmalen des Anspruchs 1 gelöst. Diese Vorrichtung kann zwischen der Weiterverarbeitungsmaschine und der die Bogen heranführenden Maschine, einem Bogenzuführtisch, Bogenanleger, einer Falzmaschine oder dergleichen, angeordnet werden und erfordert keine Eingriffe in diese Maschine. Durch die variable Übergabegeschwindigkeit läßt sich dennoch eine hochpräzise Synchronisation erreichen. Die Steuerung der variablen Übergabegeschwindigkeit läßt sich mit elektronischen Mitteln verwirklichen und erfordert daher keinen hohen Aufwand.This task is accomplished by a synchronization device the feeding of sheets with the beat of a bookbinding Processing machine with the features of the claim 1 solved. This device can be placed between the finishing machine and the one bringing up the arches Machine, a sheet feed table, sheet feeder, a folding machine or the like, are arranged and required no interference with this machine. Due to the variable transfer speed can still be a highly precise synchronization to reach. The control of the variable transfer speed can be done by electronic means realize and therefore does not require a lot of effort.

Die Bogen-Übergabevorrichtung nimmt die herangeführten Bogen vorzugsweise mit deren Zuführgeschwindigkeit entgegen und gibt sie an die Weiterverarbeitungsmaschine mit deren Durchlaufgeschwindigkeit ab. Zwischen den Zeitpunkten der Entgegennahme und der Abgabe wird der Bogen vorübergehend beschleunigt oder verzögert, je nachdem, ob er gegenüber dem Takt der Weiterverarbeitungsmaschine nacheilt oder vorauseilt.The sheet transfer device takes the introduced Sheets preferably counter to their feed speed and passes them on to the processing machine with their Throughput speed. Between the times of the Receiving and handing in the sheet becomes temporary accelerates or decelerates, depending on whether it is against the Clock of the processing machine lags or leads.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der folgenden Beschreibung einer Ausführungsform der Erfindung und aus der Zeichnung, auf die Bezug genommen wird. In der Zeichnung zeigen:

  • Fig. 1 schematisch in Seitenansicht einen Bogenzuführtisch, eine buchbindende Weiterverarbeitungsmaschine und eine dazwischen angeordnete Vorrichtung zur Synchronisierung der Bogenzuführung; und
  • Fig. 2 ein schematisches Blockschaltbild einer Steuerschaltung für den Antrieb der Vorrichtung.
    • Further features and advantages of the invention will become apparent from the following description of an embodiment of the invention and from the drawing, to which reference is made. The drawing shows:
  • Figure 1 shows schematically in side view a sheet feed table, a book-binding further processing machine and a device arranged between them for synchronizing the sheet feed. and
  • Fig. 2 is a schematic block diagram of a control circuit for driving the device.

    • Auf einem Zuführtisch 2 werden Bogen 1 mit der Geschwindigkeit V1 herangefördert. Zwischen dem Zuführtisch 2 und einer allgemein mit 7 bezeichneten, buchbindenden Weiterverarbeitungsmaschine, in diesem Falle eine Fadensiegelmaschine, ist eine allgemein mit 11 bezeichnete Bogen-Übergabevorrichtung angeordnet, die aus zwei übereinandergestellten Transportwalzen 3 besteht, von denen die untere über einen Treibriemen 8 durch einen Antriebsmotor 9 angetrieben wird. Dieser Antriebsmotor 9 ist ein Servo- oder Schrittmotor. Er wird durch die noch zu beschreibende, in Fig. 2 beispielshalber gezeigte elektronische Steuerschaltung angesteuert und kann durch diese mit variabler Geschwindigkeit betrieben werden. Die variable Geschwindigkeit vvar des Motors 9 wird durch einen Drehmelder 17 gemessen. Die Transportwalzen sind jeweils mit einem Reibbelag 4 versehen, durch den der Bogenschlupf minimiert wird. Die obere Transportwalze 3 ist mittels einer Einstellschraube 5 auf die Bogendicke einstellbar.On a feed table 2, sheets 1 are fed at the speed V 1 . Between the feed table 2 and a bookbinding further processing machine, generally designated 7, in this case a thread sealing machine, a sheet transfer device, generally designated 11, is arranged, which consists of two stacked transport rollers 3, the lower of which via a drive belt 8 by a drive motor 9 is driven. This drive motor 9 is a servo or stepper motor. It is controlled by the electronic control circuit to be described, shown by way of example in FIG. 2, and can be operated by it at variable speed. The variable speed v var of the motor 9 is measured by a resolver 17. The transport rollers are each provided with a friction lining 4, through which the sheet slip is minimized. The upper transport roller 3 can be adjusted to the sheet thickness by means of an adjusting screw 5.

    Vor dem Einlaufspalt zwischen den Transportwalzen 3 ist ein Sensor 10 angeordnet, der den Durchgang der Vorderkante jedes Bogens 1 feststellt. Der Arbeitstakt der Fadensiegelmaschine 7 wird durch einen Drehmelder 6 detektiert. Dieser Drehmelder 6 liefert ein Ausgangssignal, daß auch für die Durchlaufgeschwindigkeit V2 der Fadensiegelmaschine 7 repräsentativ ist. Die Durchlaufgeschwindigkeit V2 stimmt im wesentlichen mit der Zuführgeschwindigkeit V1 des Zuführtisches 2 überein.A sensor 10 is arranged in front of the inlet nip between the transport rollers 3 and detects the passage of the leading edge of each sheet 1. The operating cycle of the thread sealing machine 7 is detected by a resolver 6. This resolver 6 provides an output signal that is also representative of the throughput speed V 2 of the thread sealing machine 7. The throughput speed V 2 essentially coincides with the feed speed V 1 of the feed table 2.

    Anhand der Fig. 2 wird nun die Arbeitweise der Vorrichtung erläutert.2, the operation of the device explained.

    Das von dem Drehmelder 6 gelieferte, die Geschwindigkeit der Fadensiegelmaschine anzeigende Signal V2 gelangt zu einer Steuerelektronik 15, die aus diesem Signal V2 eine Bezugs-Soll-Lage für die Takteinrichtung ermittelt. Die Steuerelektronik 15 synchronisiert gleichzeitig mittels eines Verstärkers 16 die variable Geschwindigkeit vvar des Motors 9 mit der Geschwindigkeit V2 der Fadensiegelmaschine. Die Geschwindigkeit des Motors 9 wird als IST-Geschwindigkeit durch den Drehmelder 17 erfaßt. The signal V 2 supplied by the resolver 6 and indicating the speed of the thread sealing machine reaches control electronics 15, which uses this signal V 2 to determine a reference target position for the clock device. The control electronics 15 simultaneously synchronize the variable speed v var of the motor 9 with the speed V 2 of the thread sealing machine by means of an amplifier 16. The speed of the motor 9 is detected as the actual speed by the resolver 17.

    Mittels einer Signalquelle 14 kann eine Soll-Lage des Bogens entsprechend den technologischen Bedingungen vorgegeben werden. Durch Eingabe dieser Signale wird eine Verschiebung der Bogenvorderkante zum Maschinentakt erreicht.A target position of the sheet can be determined by means of a signal source 14 be specified according to the technological conditions. By entering these signals a shift of the Front sheet edge reached at machine cycle.

    Wenn die Vorderkante eines herangeführten Bogens 1 den Sensor 10 passiert, der beispielsweise als Lichtschranke ausgebildet ist, so wird die Soll-Lage der Vorderkante mit der IST-Lage der Vorderkante in der Steuerelektronik 15 verglichen, und es wird ein Differenzweg berechnet.If the leading edge of an advanced sheet 1 the sensor 10 happens, which is designed for example as a light barrier is, the target position of the leading edge with the Compared the actual position of the front edge in the control electronics 15, and a difference path is calculated.

    Die Steuerelektronik ermittelt aus diesem Differenzweg eine Beschleunigungs- und eine Bremsrampe, die über den Verstärker 16 der Synchrongeschwindigkeit des Motors 9 überlagert wird. Der Drehmelder 17 erfaßt die Relativbewegung des zu taktenden Bogens und meldet diese an die Steuerelektronik 15 zurück. Die Bogen-Übergabevorrichtung 11 arbeitet also zwischen den Zeitpunkten der Entgegennahme eines Bogens aus dem Zuführtisch 2 und der Abgabe dieses Bogens an die Fadensiegelmaschine 7 mit variabler Transportgeschwindigkeit.The control electronics determine one from this difference path Acceleration and a braking ramp that goes through the amplifier 16 of the synchronous speed of the motor 9 superimposed becomes. The resolver 17 detects the relative movement of the clocking arc and reports this to the control electronics 15 back. The sheet transfer device 11 thus works between the times of receipt of a sheet from the Feed table 2 and the delivery of this sheet to the thread sealing machine 7 with variable transport speed.

    Unmittelbar vor der Abgabe des Bogens 1 an die Fadensiegelmaschine 7, also etwa entsprechend der in Fig. 1 mit 13 bezeichneten Stelle, hat der Bogen seine Soll-Lage erreicht und wird gleichzeitig wieder mit der Synchrongeschwindigkeit V1 = V2 bewegt.Immediately prior to the delivery of the sheet 1 to the thread sealing machine 7, that is to say approximately in accordance with the position designated by 13 in FIG. 1, the sheet has reached its desired position and is simultaneously moved again with the synchronous speed V 1 = V 2 .
