Description

Die Erfindung betrifft eine Vorrichtung zum Bilden und Abfördern von Bogenstapeln in bzw. aus einer Stapelablage, mit einer Sammelbox, die von vorderen und hinteren Stapelanschlägen begrenzt ist, deren gegenseitiger Abstand auf die Formatlänge der Bogenstapel einstellbar ist, sowie mit einer Bogen zuführenden Transportbahn, die mit einer höhenverfahrbaren Plattform korrespondiert, welche in Form eines Trennrechens synchron mit der Abzugsbewegung einer Stapelentnahmevorrichtung in Bogentransportrichtung in die Stapelablage vorbewegbar ist.The invention relates to a device for forming and conveying sheet stacks in or out of a stacking tray, with a collection box, the front and rear Stacking stops is limited, their mutual distance on the format length the sheet stack is adjustable, as well as with a sheet feeding conveyor, which corresponds to a height-adjustable platform, which is in shape a separating rake in synchronism with the withdrawal movement of a stack removal device can be advanced into the stacking tray in the sheet transport direction.

Bei Vorrichtungen der eingangs bezeichneten Art, wie sie beispielsweise durch die US-PS 4 436 472 bekanntgeworden sind und üblicherweise in mehrbahniger bzw. mehrnutziger Anordnung mit zahlreichen nebeneinander angeordneten Stapelablagen zur Bildung aufeinanderfolgender Stapelreihen konzipiert werden, werden hinsichtlich einer leistungsorientierten, das Bogenmaterial schonenden und exakt ausrichtenden sowie formatflexibel anpaßbaren Arbeitsweise hohe Anforderungen an die zusammenwirkenden Maschinenkomponenten gestellt.In devices of the type described at the outset, for example by the US Pat. No. 4,436,472 have become known and are usually in multi-lane or Multi-use arrangement with numerous stacking trays arranged side by side designed to form successive batch rows are considered a performance-oriented, gentle and precise alignment of the sheet material and format-adaptable, adaptable working methods to high requirements the interacting machine components.

Der Erfindung liegt die Aufgabe zugrunde, Maßnahmen zur Optimierung des allen Einzelforderungen gerecht werdenden Arbeitsergebnisses zu treffen.The invention has for its object measures to optimize all To meet the individual requirements of the work result.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die hinteren Stapelanschläge längs der Bogentransportrichtung verstellbar angeordnet sind.
Um im Zuge der Bogenansammlung bei der Stapelbildung stets gleiche Abwurfbedingungen zwischen der Transportbahn und der Stapelablage zu gewährleisten ist außerdem vorgesehen, daß die vertikal definiert zueinander beabstandete Plattform und Transportbahn gemeinsam auf- und abbewegbar sind. Auf diese Weise ist sowohl bei der Stapelbildung eines neuen Stapels als auch beim Stapelwechsel eine immer gleiche Abwurfhöhe der in geschuppter Formation zugeführten Bogen sichergestellt.
Eine einen Formatwechsel erheblich erleichternde Weiterbildung besteht darin, daß die hinteren Stapelabschläge, die Plattform und die als Bänderbahn ausgebildete Transportbahn an einem gemeinsamen, längs der Bogentransportrichtung verstellbaren Schlitten angeordnet sind. Auf diese Weise können mit einer einzigen Einstellbewegung des Schlittens alle beteiligten Komponenten nachgeführt werden.This object is achieved in that the rear stack stops are arranged adjustable along the sheet transport direction.
In order to always ensure the same discharge conditions between the transport path and the stack storage during the formation of the sheets during stack formation, it is also provided that the vertically defined platform and transport path can be moved up and down together. In this way, the same discharge height of the sheets fed in the shingled formation is ensured both when forming a new stack and when changing a stack.
A further development that greatly facilitates a format change is that the rear stack tees, the platform and the transport path designed as a belt path are arranged on a common carriage that can be adjusted along the sheet transport direction. In this way, all components involved can be tracked with a single adjustment movement of the slide.

Eine kompakte, sowohl die einwandfreie Stapelbildung als auch die Formatanpassung erleichternde Baueinheit wird nach einem weiteren Vorschlag dadurch erhalten, daß der Schlitten längsverfahrbar an einem relativ zur Sammelbox höhenverfahrbaren Schlittenträger angeordnet ist.
Um auch die Bewegung der Plattform exakt an die jeweilige Formateinstellung anpassen zu können, wird außerdem vorgeschlagen, daß die Plattform relativ zum Schlitten mit einem entsprechend dem Abstand zwischen hinteren und vorderen Stapelanschlägen angepaßten verkürzten oder verlängerten Längshub verschiebbar ist.
Eine zusätzliche Vereinfachung und Erleichterung der Querformat-Einstellung wird gemäß einer Weiterbildung dadurch erreicht, daß die Sammelbox eine mit Stützrechen bestückte austauschbare Bodenleiste aufweist, welche mit in Querführungen verstellbaren und arretierbaren seitlichen Stapelanschlägen versehen ist.According to a further proposal, a compact structural unit that facilitates both the perfect stack formation and the format adaptation is obtained in that the slide is arranged in a longitudinally displaceable manner on a slide carrier that can be moved vertically relative to the collecting box.
In order to be able to adapt the movement of the platform exactly to the respective format setting, it is also proposed that the platform can be displaced relative to the slide with a shortened or lengthened longitudinal stroke adapted to the distance between the rear and front stacking stops.
An additional simplification and simplification of the landscape format setting is achieved according to a further development in that the collection box has an exchangeable bottom bar equipped with support rakes, which is provided with lateral stack stops which are adjustable and lockable in transverse guides.

Der mit der Erfindung erzielte Vorteil besteht darin, daß durch die Formateinstellung der hinteren Stapelanschläge die auf der Gegenseite zwischen der Stapelablage und in kürzestmöglichem Abstand nachgeordneten Quertransportmitteln hin- und herfahrende Stapelentnahmevorrichtung immer einen kürzestmöglichen Längshub ausführen kann, wodurch eine optimale Förderleistung gewährleistet ist.
Zudem wird durch die formatabhängig voreinstellbaren seitlichen Stapelanschläge an komplett bereitstehenden, schnell auswechselbaren Bodenplattformen der Sammelbox die Wirtschaftlichkeit weiter verbessert.
Durch alle mit einer einzigen Schlittenbewegung formatabhängig einstellbaren Bogenführungs- und Stapelbildungskomponenten wird der Zeitaufwand für eine Umrüstung minimiert. The advantage achieved by the invention is that the format setting of the rear stacking stops means that the stack removal device, which is arranged downstream on the opposite side between the stacking tray and at the shortest possible distance, can always carry out the shortest possible longitudinal stroke, which ensures optimal conveying capacity.
In addition, the economy is further improved by the format-dependent presettable side stacking stops on completely ready, quickly exchangeable floor platforms of the collection box.
The time required for a changeover is minimized by means of all the sheet guide and stacking components that can be adjusted depending on the format with a single slide movement.

Die Erfindung wird nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert.The invention is described below using an exemplary embodiment shown in the drawing explained in more detail.

Die Vorrichtung weist gemäß Figur 1 eine Stapelablage 1 zum Ansammeln von Papierbogen 2 zu Bogenstapeln 3 auf, die in zahlreiche, senkrecht zur Zeichenebene hintereinander liegenden Sammelboxen 4 unterteilt ist und welcher - bezogen auf die Bogen- bzw. Stapeltransportrichtung (Pfeil 6) - stromauf eine als Bänderbahn ausgebildete Transportbahn 7 für in geschuppter Formation zugeführte Papierbogen 2 sowie stromab eine als Zangengreifer 5 ausgebildete Stapelentnahmevorrichtung 8 mit anschließenden Quertransportmitteln 9 zugeordnet sind, die heb- und senkbare Transportriemen 11 mit integrierten Lufttischsegmenten 12 aufweisen.
Die Stapelablage 1 ist von vorderen Stapelanschlägen 13 und hinteren Stapelanschlägen 14 begrenzt, von denen erstere aus einer Anschlagstellung gemäß Figur 1b in eine Außerbetriebsstellung gemäß Figur 1a verschwenkbar sind.
Die hinteren Stapelanschläge 14 sind an einem in Richtung des Doppelpfeils 15 verschiebbaren Schlitten 16 befestigt, an welchem zusätzlich auch die Transportbahn 7 sowie in Längsrichtung relativ zum Schlitten 16 mit veränderbarem Hub verschiebbar eine als Trennrechen ausgebildete Plattform 17 angeordnet sind.According to FIG. 1, the device has a stacking tray 1 for collecting paper sheets 2 to form sheet stacks 3, which is divided into numerous collecting boxes 4, one behind the other perpendicular to the plane of the drawing, and which - based on the sheet or stack transport direction (arrow 6) - upstream one Transport conveyor 7 designed as a belt conveyor for paper sheets 2 fed in a shingled formation and downstream are associated with a stack removal device 8 designed as a gripper 5 with subsequent transverse transport means 9, which have lifting and lowering transport belts 11 with integrated air table segments 12.
The stacking tray 1 is delimited by front stacking stops 13 and rear stacking stops 14, of which the former can be pivoted from a stop position according to FIG. 1b into an inoperative position according to FIG. 1a.
The rear stacking stops 14 are fastened to a slide 16 which can be displaced in the direction of the double arrow 15 and on which the transport track 7 and a platform 17 designed as a separating rake are also displaceably displaceable in the longitudinal direction relative to the slide 16 with a variable stroke.

Das Abwurfende 18 der Transportbahn 7 weist einen definierten Abstand zur Plattform 17 auf.
Der Schlitten 16 ist wiederum verschiebbar an einem in Richtung des Doppelpfeils 19 höhenverfahrbaren Schlittenträger 21 angeordnet.
Die Sammelbox 4 ist mit einer Bodenplattform 22 ausgestattet, welche gemäß den Figuren 3 und 4 mit zahlreichen parallelen Stützrechen 23 bestückt ist, die an einer Bodenleiste 24 befestigt sind, welche außerdem in Querführungen 26 formatabhängig einstellbare und festsetzbare seitliche Stapelanschläge 27 trägt, wozu entsprechende Abstandshalter 28 eingefügt sind.
Die Bodenplattformen 22 werden mit formatabhängig voreingestellten seitlichen Stapelanschlägen 27 als komplette Austauschgruppe bereitgehalten. The discharge end 18 of the transport path 7 is at a defined distance from the platform 17.
The carriage 16 is in turn slidably arranged on a carriage support 21 which can be moved vertically in the direction of the double arrow 19.
The collecting box 4 is equipped with a floor platform 22, which according to FIGS. 3 and 4 is equipped with numerous parallel support rakes 23, which are fastened to a floor rail 24, which also carries lateral stacking stops 27, which can be set and fixed depending on the format, with corresponding spacers 28 are inserted.
The floor platforms 22 are kept ready as a complete exchange group with format-dependent preset side stacking stops 27.

Die Arbeitsweise der Vorrichtung ist gemäß den Figuren 1a bis 1d wie folgt: Gemäß Figur 1a wird ein aus einer definierten Anzahl angesammelter Papierbogen 2 gebildeter Bogenstapel 3 nach dem Wegschwenken des vorderen Stapelanschlags 13 durch den Zangengreifer 5 der Stapelentnahmevorrichtung 8 erfaßt und in Förderrichtung 6 aus der Stapelablage 1 heraus auf die Quertransportmittel 9 überführt, welche den Bogenstapel gemäß Figur 1d wahlweise in die senkrecht zur Zeichenebene verlaufenden, durch die Pfeilsymbole 29 bzw. 31 gekennzeichneten Richtungen abfördern.
Synchron mit der Überführungsbewegung der Stapelentnahmevorrichtung 8 folgt die aus Stabreihen bestehende Plattform 17 der Rückseite des Bogenstapels 3 bis zum Anschlag an den wieder in die Anschlagstellung zurückbewegten Stapelanschlag 13, wobei die permanent geschuppt zugeführten Papierbogen 2 gleichzeitig ohne Unterbrechung auf die Plattform 17 überführt werden.
Durch Herunterfahren des Schlittenträgers 21 in Richtung des Doppelpfeils 19 gemäß Figur 1c wird die Plattform 17 bis auf die Bodenplattform 22 der Stapelablage 1 oder gegebenenfalls bis unter deren Niveau abgesenkt und gemäß Figur 1d aus der Stapelablage 1 in die Ausgangsstellung zurückgezogen, so daß der neue Bogenstapel 3 von der Bodenplattform 22 übernommen wird.
Durch die anschließende Aufwärtsbewegung des Schlittenträgers 21 in Richtung des Doppelpfeils 19 wird das Abwurfende 18 der Transportbahn 7 in dem Maße angehoben wie die Stapelhöhe des Bogenstapels 3 zunimmt, so daß immer eine gleichbleibende Abwurfhöhe für die Papierbogen 2 gewährleistet bleibt.The operation of the device according to FIGS. 1a to 1d is as follows: According to FIG. 1a, a sheet stack 3 formed from a defined number of accumulated paper sheets 2 is gripped by the gripper 5 of the stack removal device 8 after the front stack stop 13 has been swung away and in the conveying direction 6 from the Stacking tray 1 is transferred to the transverse transport means 9, which optionally transport the sheet stack according to FIG. 1d in the directions perpendicular to the plane of the drawing, identified by the arrow symbols 29 and 31.
In synchronism with the transfer movement of the stack removal device 8, the platform 17 consisting of rows of bars follows the back of the sheet stack 3 up to the stop against the stack stop 13 moved back into the stop position, the permanently scaled paper sheets 2 being simultaneously transferred to the platform 17 without interruption.
By moving the slide carrier 21 in the direction of the double arrow 19 according to FIG. 1c, the platform 17 is lowered to the base platform 22 of the stacking tray 1 or possibly below its level and, according to FIG. 1d, is withdrawn from the stacking tray 1 into the starting position, so that the new sheet stack 3 is taken over by the floor platform 22.
Due to the subsequent upward movement of the carriage carrier 21 in the direction of the double arrow 19, the discharge end 18 of the transport path 7 is raised to the extent that the stack height of the sheet stack 3 increases, so that a constant discharge height for the paper sheets 2 is always guaranteed.

Für eine gemäß den Figuren 2a und 2b vorgenommene Formatverstellung werden durch Einwärtsverschiebung des Schlittens 16 in Richtung des Doppelpfeils 15 der hintere Stapelanschlag 14 sowie das Abwurfende 18 der Transportbahn 7 und die Plattform 17 abstandsvermindernd auf den vorderen Stapelanschlag 13 zubewegt.
Eine Anpassung des Querformats senkrecht zur Zeichenebene erfolgt durch Austausch der Bodenplattform 22 gegen eine bereitstehende, mit entsprechend voreingestellten seitlichen Stapelanschlägen 27 bestückte Ersatz-Bodenplattform.For a format adjustment carried out according to FIGS. 2a and 2b, the rear stack stop 14 and the shedding end 18 of the transport path 7 and the platform 17 are moved towards the front stack stop 13 in a distance-reducing manner by inward displacement of the slide 16 in the direction of the double arrow 15.
The landscape format is adjusted perpendicular to the plane of the drawing by replacing the floor platform 22 with a replacement floor platform which is provided and is equipped with correspondingly preset lateral stacking stops 27.

Der Längshub der Plattform 17 wird entsprechend der Längsverkürzung der Stapelablage 1 angepaßt, während der Längshub der Stapelentnahmevorrichtung 8 durch die stets gleichbleibende Hubbegrenzung am vorderen Stapelanschlag 13 im wesentlichen unverändert bleibt, bei der beschriebenen Formatverstellung wegen des kleineren Bogenformats sogar verkürzt wird.The longitudinal stroke of the platform 17 is in accordance with the longitudinal shortening of the stacking tray 1 adapted during the longitudinal stroke of the stack removal device 8 due to the always constant stroke limitation on the front stack stop 13 in remains essentially unchanged, due to the format adjustment described the smaller sheet format is even shortened.
