Abstract

The apparatus for separating folded and perforated or creased endless or reel papers, which form an uninterrupted stack, comprises a conveyor belt 9 conveying the same to a separating station, in order to permit an automatic separation of the stack into individual stacks 7a with a predetermined number of paper sheets. For this purpose, a separating sword 2 is moved preferably from below between the sheets of the stack, so that a stack 7a is formed with the desired number of individual sheets. The small cavity 10 running in the longitudinal direction and formed by the separating sword 2 is used for receiving a knife 4, which is moved at right angles over the stack, in order to separate the same at a perforation or fold. Pivotable removal bolts 1 are used for conveying away the separated stack 7a and for transfer to a second conveyor belt 5. The removal bolts 1 are then moved back into the starting position, so that the separating sword 2 can be extended out of the conveying area of the stack and a new separating process can be carried out. This permits an automatic separation into small stacks with predetermined numbers at virtually any random point.

Description

Die Erfindung betrifft eine Vorrichtung nach dem Oberbegriff des Anspruches 1 (siehe DE-U-8509218).The invention relates to a device according to the preamble of claim 1 (see DE-U-8509218).

Diese Vorrichtung dient der Verarbeitung eines Endlos-Papiers, das durch Falten mit einer entsprechenden Perforation oder durch Falzen einen entsprechenden Stapel bildet. Die einzelnen Papiere werden in einer vorgeschalteten Vorrichtung bedruckt, gefaltet, perforiert oder gefalzt. Gegebenenfalls liegen mehrere Lagen mit dazwischenliegendem Durchschlagpapier übereinander. Aus der Druck- und Falzmaschine tritt ein fortlaufender Stapel mit den entsprechenden einzelnen Papieren aus. Normalerweise liegen die Falten oder Falze abwechselnd oben oder unten. Um die Papiere nach bestimmten Stückzahlen, beispielsweise zu 1 000, 2 000. 3 000 usw. zu verpacken, ist es erforderlich, den fortlaufenden Stapel entsprechend an der Perforation oder an den Falzen zu trennen.This device is used to process a continuous paper, which forms a corresponding stack by folding with a corresponding perforation or by folding. The individual papers are printed, folded, perforated or folded in an upstream device. If necessary, several layers with interleaved carbon paper are on top of each other. A continuous stack of the corresponding individual papers emerges from the printing and folding machine. Usually the folds or folds are alternately up or down. In order to pack the papers according to certain quantities, for example 1,000, 2,000, 3,000, etc., it is necessary to separate the continuous stack at the perforation or at the folds.

Bisher geschieht dieses von Hand, beispielsweise dadurch, daß die Druckmaschine nach der gewünschten Anzahl eine rote Markierung aufbringt, die der Bedienungsperson dann anzeigt, daß an dieser Stelle getrennt werden muß.So far, this has been done by hand, for example by the printing machine applying a red mark after the desired number, which then indicates to the operator that separation must be carried out at this point.

Der Erfindung liegt nun die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art zu schaffen, die das Abtrennen automatisch durchführt und dabei gleichzeitig einen sicheren Weitertransport des abgetrennten Stapels gewährleistet.The invention is based on the object of creating a device of the type mentioned at the outset which carries out the separation automatically and at the same time ensures safe further transport of the separated stack.

Diese Aufgabe wird durch das Kennzeichen des Anspruches 1 gelöst.This object is achieved by the characterizing part of claim 1.

Erfindungsgemäß wird vorzugsweise von unten ein Trennschwert nach Eingang eines entsprechenden Zählimpulses zwischen die Papiere geschoben, so daß diese getrennt werden. In Förderrichtung vor dem Trennschwert entsteht dann ein Stapel, der die gewünschte Anzahl von zusammenhängenden Bögen aufweist. Das Trennschwert wird bis in die Nähe des dann oben liegenden Falzes oder der entsprechenden Perforation bewegt, so daß hier ein quer zur r Förderrichtung durchgehender Hohlraum entsteht. In diesen Hohlraum kann dann ein Messer, wie ein Brieföffner, hinein und durch diesen hindurchgefahren werden. Das Messer ist verhältnismäßig stumpf, damit auch wirklich ein Abtrennen an der Perforation gewährleistet ist.According to the invention, a separating sword is preferably pushed from below after the receipt of a corresponding counting pulse between the papers, so that these are separated. A stack is then created in the conveying direction in front of the separating sword, which has the desired number of connected arches. The separating sword is moved up to the vicinity of the fold or the corresponding perforation, which then lies at the top, so that a cavity is formed which is transverse to the conveying direction. A knife, such as a letter opener, can then be inserted into and through this cavity. The knife is relatively blunt so that the perforation can really be cut off.

Die Vorrichtung kann dann weiterhin so ausgebildet sein wie in den Ansprüchen 2 bis 6 angegeben. Die Verwendung eines in Förderrichtung bewegbaren und schwenkbaren Abnahmeriegels stellt eine besonders vorteilhafte Ausführungsform dar, um den relativ labilen abgetrennten Stapel zu handhaben und einer Weiterverarbeitung zuzuführen.The device can then also be designed as specified in claims 2 to 6. The use of a removal bar which is movable and pivotable in the conveying direction represents a particularly advantageous embodiment for handling the relatively unstable separated stack and for further processing.

Im folgenden wird die Erfindung unter Hinweis auf die Zeichnung anhand eines Ausführungsbeispiels näher erläutert :The invention is explained in more detail below with reference to the drawing using an exemplary embodiment:

Es zeigt :

  • Fig. 1 eine schematische Seitenansicht einer Ausführungsform einer Vorrichtung nach der Erfindung ;
  • Fig. 2 die Einzelheit X der Fig. 1.
It shows :
  • Figure 1 is a schematic side view of an embodiment of a device according to the invention.
  • 2 shows the detail X of FIG. 1st

Die in der Zeichnung dargestellte Vorrichtung besteht aus einem ersten Förderband 9, das einen Stapel aus Endlos-Papier von einer nicht gezeigten Druckmaschine aufnimmt. Dieser Stapel 7 besteht aus zick-zack-formig gefalteten und in den Falten perforierten Papieren, ggf. aus mehreren Lagen auch unterschiedlicher Papierarten. Die Falten mit der Perforation liegen abwechselnd oben und unten. Das erste Förderband 9 ist geringfügig schräg nach oben gerichtet. An seinem Ende am höchsten Punkt geht das Förderband 9 in eine schräg nach unten geneigte Förderebene 11 über. Diese wird durch entsprechende Schienen gebildet.The device shown in the drawing consists of a first conveyor belt 9 which receives a stack of continuous paper from a printing machine, not shown. This stack 7 consists of papers folded in a zigzag shape and perforated in the folds, possibly of several layers of different types of paper. The folds with the perforation alternate between top and bottom. The first conveyor belt 9 is directed slightly obliquely upwards. At its end at the highest point, the conveyor belt 9 merges into a conveyor plane 11 which is inclined downwards. This is formed by appropriate rails.

An dem Übergangspunkt sitzt die eigentliche Trenneinrichtung. Diese besteht aus einem auf-und abbewegbaren Trennschwert 2 und einer Schneideinrichtung 8 mit einem Messer 4. Einzelheiten sind in Fig. 2 dargestellt.The actual separation device is located at the transition point. This consists of a separating sword 2 that can be moved up and down and a cutting device 8 with a knife 4. Details are shown in FIG. 2.

Im Bereich der Förderebene 11 befindet sich ein Abnahmeriegel 1 mit einem rechtwinklig gegen die Förderrichtung gerichteten Kipprücken 6. Der Abnahmeriegel 1 und der Kipprücken 2 sind so schwenkbar, wie in Fig. 1 strichpunktiert angeordnet. Weiterhin sind sie bis zum unten liegenden Ende der Förderebene 11 bewegbar. Dort beginnt das zweite Förderband 5, das zu einer Weiterverarbeitungseinrichtung führt.In the area of the conveying plane 11 there is a removal bar 1 with a tilting back 6 directed at right angles to the conveying direction. The removal bar 1 and the tilting back 2 can be pivoted as shown in dot-dash lines in FIG. 1. Furthermore, they can be moved up to the end of the conveying plane 11 lying below. There begins the second conveyor belt 5, which leads to a further processing device.

Im Betrieb wird der Stapel 7 aus der nicht gezeigten Druck- und Falzmaschine auf das erste Förderband 9 übergeben. Es entsteht ein fortlaufender Stapel aus einer entsprechenden großen Anzahl von einzelnen Blättern. Wenn dieser Stapel, bedingt durch die Förderung durch das zweite Band, den höchten Punkt und damit die Trennebene erreicht hat, steht dort Abnahmeriegel und das erste Blatt gelangt an ihm zur Anlage. Mit der Fördergeschwindigkeit des ersten Förderbandes 9 bewegt sich der Abnahmeriegel in der Förderebene 11 in Förderrichtung schräg nach unten und zwar solange, bis die entsprechende Anzahl von Blättern in dem abzutrennenden Stapel 7a vorhanden ist. Dieses kann durch Zählimpulse von der Druckmaschine aus gesteuert werden. Dann wird das Trennschwert 2 vorgeschoben. Das Trennschwert 2 und der Abnahmeriegel 1 nehmen dann die in Fig. 1 mit ausgezogenen Linien gezeichnete Stellung ein.In operation, the stack 7 is transferred from the printing and folding machine, not shown, to the first conveyor belt 9. A continuous stack of a correspondingly large number of individual sheets is created. When this stack has reached the highest point and thus the parting line due to the conveyance by the second belt, there is an acceptance bar and the first sheet comes into contact with it. With the conveying speed of the first conveyor belt 9, the take-off bar moves obliquely downward in the conveying plane 11 in the conveying direction until the corresponding number of sheets are present in the stack 7a to be separated. This can be controlled by counting pulses from the printing press. Then the separating sword 2 is advanced. The separating sword 2 and the removal bar 1 then assume the position shown in solid lines in FIG. 1.

Das Trennschwert läßt oben einen langgestreckten Hohlraum 10 (Fig. 2) frei, in den dann das verhältnismäßig stumpfe Messer 4, gesteuert durch die Trennvorrichtung 8, einfahren kann. Das Messer wird quer über den Stapel bewegt und trennt diesen ab. Das Messer wird dann in seine Ausgangsstellung zurückbewegt.The separating sword leaves an elongated cavity 10 at the top (FIG. 2) into which the relatively blunt knife 4, controlled by the separating device 8, can then enter. The knife is moved across the stack and cuts it off. The knife is then moved back to its original position.

Der Abriahmeriegel 1 wird zusammen mit dem Kipprücken 6 dann in die in Fig. 1 strichpunktiert gezeigte Stellung geschwenkt. Gleichzeitig werden diese Teile mit dem auf ihm liegenden abgetrennten Stapel 7a nach unten bewegt. Hier erfolgt die Übergabe des abgetrennten Stapels auf das zweite Förderband 5. Anschließend wird der Abnahmeriegel mit dem Kipprücken in die Ausgangsstellung (Kipprücken 6 parallel zur Förderebene 11 zurückgeschwenkt und nach oben in die Ausgangsstellung bewegt. Der Kipprücken 6 ist federnd gelagert, so daß er entsprechend zurückgedrückt wird, um die Bewegung des Abnahmeriegels in die höchste Stellung nicht zu behindern. Wenn der Abnahmeriegel seine höchste Stellung erreicht hat. kann das Trennschwert 2 zurückgefahren werden, damit ein neuer Stapel 7a im oberen Teil der Förderebene 11 zusammengestellt werden kann. Der Vorgang wiederholt sich dann.The locking bar 1 is then pivoted together with the tilting back 6 into the position shown in broken lines in FIG. 1. At the same time these parts are abge with the lying on it separated stack 7a moved down. This is where the separated stack is transferred to the second conveyor belt 5. Then the take-off bar with the tilting back is pivoted back into the starting position (tilting back 6 parallel to the conveying plane 11 and moved upwards into the starting position. The tilting back 6 is spring-loaded so that it corresponds accordingly is pressed back so as not to hinder the movement of the take-off bar into the highest position, when the take-off bar has reached its highest position, the separating sword 2 can be moved back so that a new stack 7a can be put together in the upper part of the conveying plane 11. The process is repeated then.

Die Bewegung des Abnahmeriegels 1 mit dem Kipprücken 6 aus der Stellung I bis in die Stellung II (Fig. 1) erfolgt mit der Geschwindigkeit des ersten Förderbandes 9. Die Bewegung aus der Stellung 11 bis in die Stellung 111 und zurück in die Stellung I erfolgt sehr schnell, da während dieser Bewegung das Trennschwert 2 einen weiteren Vorschub des Stapels 7 verhindert. Dieses ist aber normalerweise möglich, da der Stapel 7 eine entsprechende Elastizität aufweist Wenn dieses nicht möglich ist, müsste dafür Sorge getragen werden, daß das Trennschwert 2 sich während der « Abwesenheit »des Abnahmeriegels ebenfalls mit der Geschwindigkeit des ersten Förderbandes 9 bewegt. Die Abnahme oder Übergangszeit ist aber, wie gesagt, normalerweise so kurz, daß auf diese Bewegung des Trennschwertes verzichtet werden kann.The movement of the take-off bar 1 with the tilting back 6 from position I to position II (FIG. 1) takes place at the speed of the first conveyor belt 9. The movement from position 11 to position 111 and back to position I takes place very quickly, since the separating sword 2 prevents a further advance of the stack 7 during this movement. However, this is normally possible because the stack 7 has a corresponding elasticity. If this is not possible, care would have to be taken that the separating sword 2 also moves at the speed of the first conveyor belt 9 during the “absence” of the removal bar. However, the decrease or transition period is, as I said, usually so short that this movement of the separating sword can be dispensed with.

Beim Betrachten der Fig. 2 wird deutlich, daß das Trennschwert 2 oben einen langgestreckten Hohlraum 10 freiläßt, in den das relativ stumpfe Messer 4 eingeführt und dann quer zur Förderrichtung zum Trennen vorgeschoben werden kann. Das Messer ist relativ stumpf, damit an der Perforation getrennt und nicht an einer anderen Stelle geschnitten wird.2, it becomes clear that the separating sword 2 leaves an elongated cavity 10 open at the top, into which the relatively blunt knife 4 can be inserted and then pushed forward for cutting at right angles to the conveying direction. The knife is relatively blunt so that the perforation is separated and not cut in another place.

Die Erfindung betrifft eine Vorrichtung zum . Trennen von gefalteten und perforierten oder gefalzten Endlospapieren, die einen fortlaufenden Stapel bilden. Dieser Stapel wird auf einem Förderer zu einer Trennstation gefördert, um ein automatisches Trennen des fortlaufenden Stapels in Einzelstapeln mit einer bestimmten Stückzahl von Papierblättern zu ermöglichen. Zu diesem Zweck wird ein Trennschwert 2 vorzugsweise von unten zwischen die Blätter des Stapels geschoben, so daß ein Stapel 7a mit der gewünschten Stückzahl einzelner Blätter separiert wird. Der durch das Trennschwert gebildete, in Längsrichtung verlaufende kleine Hohlraum, dient der Aufnahme eines Messers 4, das dann quer über den Stapel bewegt wird, um diesen an einer Perforation oder an einem Falz zu trennen. Ein Abnahmeriegel 6, der vorzugsweise schwenkbar ist, dient der Entfernung des abgetrennten Stapels 7a und der Weitergabe auf ein Förderband 5. Der Abnahmeriegel 6 wird dann zurück in die Ausgangsstellung bewegt, so daß das Trennschwert 2 dann aus dem Förderbereich des Stapels herausgefahren werden kann und ein neuer Trennvorgang durchführbar ist. Hierdurch ist eine automatische Trennung in kleine Stapel mit bestimmten Stückzahlen und eine gleichzeitige ordnungsgemäße Handhabung des labilen Stapels möglich.The invention relates to a device for. Cut folded, perforated, or folded continuous forms that form a continuous stack. This stack is conveyed on a conveyor to a separating station in order to enable the continuous stack to be automatically separated into individual stacks with a certain number of sheets of paper. For this purpose, a separating sword 2 is preferably pushed from below between the sheets of the stack, so that a stack 7a with the desired number of individual sheets is separated. The small cavity formed by the separating sword and running in the longitudinal direction serves to receive a knife 4, which is then moved across the stack in order to separate it at a perforation or at a fold. A removal bar 6, which is preferably pivotable, serves to remove the separated stack 7a and to pass it on to a conveyor belt 5. The removal bar 6 is then moved back into the starting position, so that the separating sword 2 can then be moved out of the conveying area of the stack and a new separation process can be carried out. This enables automatic separation into small stacks with certain quantities and simultaneous proper handling of the unstable stack.
