Description

Die Erfindung betrifft Vorrichtung zum Bilden von Stapeln aus Bogen, mit einem Schneidzylinder, der von einer endlosen Bahn nacheinander Bogen abschneidet, mit einem in Transportrichtung nach dem Schneidzylinder angeordneten Bogenauszugband, von dem die Bogen nacheinander mit einem Schläger zu einem Schuppenstrom auf ein Schuppentransportband abgelegt werden und mit einer nachfolgenden Bogentransportvorrichtung zum Bilden der Stapel, wobei die Bogentransportvorrichtung in gleichen Abständen Bogenhalter aufweist und das Schuppentransportband so angetrieben ist, dass es pro Bogen einen vorbestimmten Weg ausführt, welcher dem genannten Abstand zwischen den Bogenhaltern entspricht.The invention relates to apparatus for forming stacks of sheets, comprising a cutting cylinder which sequentially cuts sheets from an endless web, with a sheet discharge belt arranged in the transporting direction after the cutting cylinder, from which sheets are successively deposited with a racket to a shingled stream on a shingled conveyor belt and with a subsequent sheet transporting device for forming the stacks, wherein the sheet transport device has sheet holders at equal intervals and the shingled transport belt is driven to execute a predetermined path per arc corresponding to said distance between the sheet holders.

Eine Vorrichtung der genannten Art ist bekannt und hat sich in der Praxis an sich bewährt. Bei dieser ist der Schneidzylinder ein formatvariabler Querschneider, mit dem von einem endlosen Papierband Bogen abgeschnitten werden. Aus diesen Bogen wird über einen sogenannten Wasserfall ein Schuppenstrom gebildet. Dieser Schuppenstrom wird gegen einen Frontanschläger einer Stapelvorrichtung geschoben und damit ein Stapel gebildet. Das Schuppentransportband ist für seinen Antrieb mechanisch mit dem Papiervorzug des Querschneiders gekoppelt.A device of the type mentioned is known and has proven itself in practice. In this case, the cutting cylinder is a variable-format cross-cutter, are cut off from an endless paper tape sheet. From this arc a shingled stream is formed over a so-called waterfall. This scale flow is pushed against a front stopper of a stacking device and thus formed a stack. The shingled conveyor belt is mechanically coupled with the paper advantage of the cross cutter for its drive.

Hierdurch ergibt sich immer ein relativer Schuppenabstand zur Bogenlänge, beispielsweise 1/10 der Bogenlänge. Bei einem Formatwechsel wird entsprechend der Schuppenabstand geändert.This always results in a relative scale distance to the arc length, for example, 1/10 of the arc length. In the case of a format change, the scale spacing is changed accordingly.

Die vorveröffentlichte DE 26 03 171 A vermittelt ein Verfahren und eine Vorrichtung zur Bildung eines Bogenstapels aus einer Folge von sich auf einem Transportband schuppenförmig unterlappenden Bogen. An Saugern werden die Bogen um Umlenkrollen transportiert und auf einen Stapel abgelegt.The pre-published DE 26 03 171 A teaches a method and an apparatus for forming a sheet pile from a sequence of on a conveyor belt scale-overlapping arc. At suckers, the sheets are transported around deflection rollers and placed on a stack.

Die vorveröffentlichte DE 42 31 891 A beschreibt ein Verfahren zum automatischen Aufstapeln von Bogen, die von einer Transportvorrichtung über einen Schuppenleger auf einem längeren Weg unter Reibungsschluss einer Bogenstapeleinrichtung zugeführt werden.The pre-published DE 42 31 891 A describes a method for automatically stacking sheets which are fed by a transport device via a scale depositor on a longer path under frictional engagement of a sheet stacker.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der genannten Art zu schaffen, die eine höhere Stapelgeschwindigkeit ermöglicht.The invention has for its object to provide a device of the type mentioned, which allows a higher stacking speed.

Die Aufgabe ist gemäss Anspruch 1 gelöst.
Bei der erfindungsgemässen Vorrichtung wird der Schuppenstrom nicht gegen einen Frontanschlag geschoben, sondern die Bogen werden mit der Bogentransportvorrichtung ziehend zum Frontanschlag gebracht. Damit ergibt sich eine sichere Führung der Bogen, und Bogen die lang und aus dünnem Papier bestehen können auch bei hohen Geschwindigkeiten sicher bis zum Frontanschlag gebracht werden. Die Abstände der Bogen auf dem Schuppentransportband sind so gesteuert, dass sie den Abständen der Bogenhalter der Bogentransportvorrichtung entsprechen. Die einzelnen Bogen können damit von der Bogentransportvorrichtung bzw. den Bogenhaltern sicher gefasst werden.The problem is solved according to claim 1.
In the inventive device, the scale flow is not pushed against a front stop, but the sheets are brought to the front stop with the sheet transport device pulling. This results in a secure guidance of the bow, and sheets that are long and made of thin paper can be safely brought to the front stop even at high speeds. The distances of the sheets on the scale conveyor belt are controlled so that they correspond to the distances of the sheet holder of the sheet transport device. The individual sheets can thus be taken safely by the sheet transport device or the sheet holders.

Bei der erfindungsgemässen Vorrichtung ist das Schuppentransportband für seinen Antrieb mit dem Papiervorzug nicht mechanisch gekoppelt. Bei eienem Formatwechsel muss somit eine mechanische Antriebskupplung, wie beispielsweise ein bisher übliches Wechselradgetriebe, nicht umgestellt werden. Über alle Formate und insbesondere über alle Blattlängen ist ein konstanter Schuppenabstand gewährleistet.In the apparatus according to the invention the shingled conveyor belt is for his Drive with the paper advantage not mechanically coupled. When eienem format change thus a mechanical drive clutch, such as a previously common change gear, must not be changed. Over all formats and especially over all blade lengths a constant scale distance is guaranteed.

Eine besonders funktionssichere und kostengünstig herstellbare Vorrichtung ergibt sich dann, wenn gemäss einer Weiterbildung der Erfindung das Schuppentransportband formschlüssig von einer im Bogentakt drehenden Welle angetrieben ist. Die Welle ist insbesondere im Takt des Schneidzylinders oder im Takt des Schlägers angetrieben. Der Antrieb ist hier insbesondere ein Motor. Nach einer Alternative ist vorgesehen, dass das Schuppentransportband von einem separaten und einer Steuervorrichtung zugeordneten Antrieb angetrieben ist.A particularly reliable and cost-effective to produce Device results when, according to a development of the invention, the flake conveyor belt is positively driven by a rotating shaft in the bow cycle. The shaft is driven in particular in time with the cutting cylinder or in time with the racket. The drive is here in particular a motor. According to an alternative, it is provided that the shingled conveyor belt is driven by a separate drive assigned to a control device.

Ein besonders schonender Transport der Bogen mit der Bogentransportvorrichtung ergibt sich dann, wenn gemäss einer Weiterbildung die Bogenhalter als Saugnäpfe ausgebildet sind. Die Bogenhalter bzw. die Saugnäpfe fassen die Bogen und ziehen diese in Transportrichtung zur Stapelvorrichtung.A particularly gentle transport of the sheet with the sheet transport device results when, according to a development, the sheet holder are designed as suction cups. The sheet holders and the suction cups grasp the sheets and pull them in the transport direction to the stacking device.

Ein besonders exakter Schuppenstrom ergibt sich dann, wenn gemäss einer Weiterbildung eine Stopprolle vorgesehen ist, mit welcher der Schuppenstrom an das Schuppentransportband angepresst wird.A particularly accurate scale flow is obtained when, according to a development, a stop roller is provided, with which the scale flow is pressed against the shingled conveyor belt.

Weitere vorteilhafte Merkmale ergeben sich aus den abhängigen Patentansprüchen, der nachfolgenden Beschreibung sowie der Zeichnung.Further advantageous features emerge from the dependent claims, the following description and the drawings.

An embodiment of the invention will be explained in more detail with reference to the drawing. Show it:

Die in Fig. 1 gezeigte erfindungsgemässe Vorrichtung 1 weist einen Schneidzylinder 2 auf, der im Gegenuhrzeigersinn angetrieben ist und einen Querschneider mit Schneidmessern 24 bildet. Der Schneidzylinder bildet einen Vorzug für eine endlose Bahn 10, insbesondere eine Papierbahn. Diese Bahn 10 ist um eine Umlenkrolle 9 gelegt, die im Uhrzeigersinn dreht und die Papierbahn 10 zum Schneidzylinder 2 hin umlenkt. Die Bahn 10 wird von einer hier nicht gezeigten Rolle abgezogen. Der angetriebene Schneidzylinder 2 schneidet die Bahn 10 in Querrichtung zu einzelnen Bogen 12, die auf einem Bogenauszugband 3 in Richtung des Pfeiles 11 transportiert werden. Das Bogenauszugband 3 kann auch aus mehreren Teilbändern bestehen. Die Bogen 12 werden hintereinander auf dem Bogenauszugband 3 transportiert.In the Fig. 1 shown inventive device 1 has a cutting cylinder 2 which is driven in the counterclockwise direction and forms a cross cutter with cutting blades 24. The cutting cylinder forms an advantage for an endless web 10, in particular a paper web. This web 10 is placed around a deflection roller 9, which rotates clockwise and deflects the paper web 10 to the cutting cylinder 2 out. The web 10 is withdrawn from a role, not shown here. The driven cutting cylinder 2 cuts the web 10 in the transverse direction to individual sheets 12 which are transported on a sheet extraction belt 3 in the direction of the arrow 11. The sheet extraction belt 3 may also consist of several subbands. The sheets 12 are transported in succession on the sheet extraction belt 3.

Das Bogenauszugband 3 führt die Bogen 12 einer Schlägerwelle 4 zu, an welcher ein sogenannter Schläger 4a befestigt ist, der in Richtung des Pfeiles 13 um die Welle 4 rotiert. Mit dem Schläger 4a werden die Bogen 12 jeweils an einem nachlaufenden Rand 12a nach unten auf ein Schuppentransportband 5 geschlagen. Hierbei wird ein Schuppenstrom S gebildet. Der Antrieb des Schuppentransportbandes 5 erfolgt mit einem separaten Antrieb 6, beispielsweise einem Elektromotor, der von einer Steuervorrichtung 23 gesteuert ist. Wesentlich ist nun, dass das Schuppentransportband 5 so gesteuert ist, dass es pro Bogen einen Weg D1 zurücklegt. Dieser Weg D1 ergibt gemäss Fig. 2 einen Schuppenabstand D1 und dieser entspricht dem Abstand D2 zwischen benachbarten Haltern 19 einer Transportvorrichtung 8. Der Antrieb 6 ist so gesteuert, dass unabhängig vom Format bzw. der Bogenlänge der Bogen 12 dieser Abstand D1 eingehalten wird. Das Schuppentransportband 5 kann alternativ auch von einer im Bogentakt drehenden Welle beispielsweise von der Schlägerwelle 4 oder von der Welle des Schneidzylinders 2 angetrieben sein.The sheet extraction belt 3 leads the sheet 12 to a racket shaft 4, to which a so-called racket 4a is fixed, which rotates in the direction of the arrow 13 about the shaft 4. With the bat 4a, the sheets 12 are each struck at a trailing edge 12a down on a shingled conveyor belt 5. Here, a scale flow S is formed. The drive of the scale conveyor belt 5 is carried out with a separate drive 6, for example an electric motor, which is controlled by a control device 23. It is essential that the shingled conveyor belt 5 is controlled so that it covers a path D1 per arc. This way D1 results according to Fig. 2 a scale distance D1 and this corresponds to the distance D2 between adjacent holders 19 of a transport device 8. The drive 6 is controlled so that regardless of the format or the arc length the sheet 12 of this distance D1 is maintained. The shingled conveyor belt 5 may alternatively also be driven by a shaft rotating in the bowing cycle, for example by the club shaft 4 or by the shaft of the cutting cylinder 2.

Die Transportvorrichtung 8 ist so angetrieben, dass sie pro Umdrehung des Schneidzylinders 2 genau um eine Taktlänge D2 und somit um einen Abstand zwischen zwei benachbarten Bogenhaltern 19 weiterläuft. Die Transportvorrichtung kann von einem hier nicht gezeigten separaten Motor oder ebenfalls von der im Bogentakt laufenden Schlägerwelle 4 oder der Welle des Schneidzylinders angetrieben sein. Das Schuppentransportband 5 besitzt somit eine Geschwindigkeit V1, welche der Geschwindigkeit V2 der Transportvorrichtung 8 entspricht.The transport device 8 is driven so that it continues to rotate per revolution of the cutting cylinder 2 exactly by a stroke length D2 and thus by a distance between two adjacent sheet holders 19. The transport device can be driven by a separate motor, not shown here, or also by the bow clock shaft 4 running in the bow cycle or the shaft of the cutting cylinder. The shingled conveyor belt 5 thus has a speed V1, which corresponds to the speed V2 of the transport device 8.

Auf dem Schuppentransportband 5 wird der Schuppenstrom S von einer Stopprolle 7, auch Bremsrolle genannt, angepresst. Die Stopprolle 7 ist um eine Achse 14 schwenkbar und weist ein verstellbares Gewicht 15 auf. Durch Verstellen des Gewichtes 15 kann die Bremswirkung eingestellt werden. Die Stopprolle 7 stellt sicher, dass der Schuppenstrom S mit der Geschwindigkeit V1 des Schuppentransportbandes 5 transportiert wird.On the scale conveyor belt 5, the scale flow S is pressed by a stop roller 7, also called a brake roller. The stop roller 7 is pivotable about an axis 14 and has an adjustable weight 15. By adjusting the weight 15, the braking effect can be adjusted. The stop roller 7 ensures that the scale flow S is transported at the speed V1 of the shingled conveyor belt 5.

Die Transportvorrichtung 8 weist ein endloses Band 25 auf, das um eine Umlenkrolle 18 und eine hier nicht gezeigte Antriebsrolle gelegt ist. Am endlosen Band 25 sind in gleichen Abständen jeweils nebeneinander zwei oder mehr als zwei Bogenhalter 19 befestigt. Diese Bogenhalter 19 sind beispielsweise vorzugsweise Saugnäpfe. Diese Saugnäpfe 19 erfassen unterhalb der Umlenkrolle 18 jeweils einen Bogen 12 und ziehen diesen in Fig. 1 von links nach rechts. Am unteren Trum 8a des endlosen Bandes 8 werden somit mehrere Bogen 12 transportiert. Diese Bogen 12 werden zu einer in Fig. 2 lediglich angedeuteten Stapelvorrichtung transportiert und zu einem Stapel 22 abgelegt. In der Fig. 2 sind zudem strichpunktiert die Stellen 21 angedeutet, an denen die Bogen 12 jeweils von zwei Bogenhaltern 19 gefasst werden. Die Bogen 12 können unterschiedliche Formate aufweisen. Aber auch bei unterschiedlichen Formaten und insbesondere unterschiedlichen Bogenlängen sind die Abstände D1 und D2 genau gleich. Durch den ziehenden Transport der Bogen 12 zur Stapelvorrichtung 26 kann eine Beschädigung der Bogen 12 sowie auch eine Störung vermieden werden. Dies ist auch bei hohen Geschwindigkeiten möglich. Die Bogen 12 werden hier somit gezogen und nicht wie bisher geschoben und gegen einen Frontanschläger geschossen.The transport device 8 has an endless belt 25 which is placed around a deflection roller 18 and a drive roller, not shown here. On the endless belt 25 two or more than two sheet holder 19 are attached at equal intervals each side by side. These sheet holders 19 are for example preferably suction cups. These suction cups 19 detect below the guide roller 18 each have a sheet 12 and pull it in Fig. 1 left to right. At the bottom strand 8a of the endless belt 8 thus become transported several sheets 12. These bows 12 become one in Fig. 2 transported only indicated stacking device and stored to a stack 22. In the Fig. 2 are also dash-dotted lines indicated the points 21, where the sheet 12 are each taken by two sheet holders 19. The sheets 12 may have different formats. But even with different formats and in particular different arc lengths, the distances D1 and D2 are exactly the same. By pulling the sheet 12 to the stacking device 26, damage to the sheet 12 and a fault can be avoided. This is possible even at high speeds. The bow 12 are thus pulled here and not pushed as before and shot against a front attacker.
