Abstract

Known devices for stacking sheets (1), especially for stacking on pallets (4) paper or cardboard sheets conveyed in an overlapping stream, comprise a device (2) for conveying the sheets (1) to a depositing platform (5) which is suspended on pillars (6) in the stacking area such that it can be raised and lowered. According to the invention the depositing platform (5) is attached to two cantilever beams (9) which are each mounted on a pillar (6) in a vertically movable manner. The two cantilever beams (9) are preferably mounted on the arrival-side pillars (6) of the frame. The invention has the advantage that only two instead of four support elements are required for the depositing platform and in that it allows for a modular construction with simple adjustment of both the length and width of the stacking area.

Kurze Beschreibung der ZeichnungBrief description of the drawing
Die Zeichnung dient zur Erläuterung der Erfindung anhand eines vereinfacht dargestell- ten Ausführungsbeispiels.The drawing serves to explain the invention on the basis of a simplified exemplary embodiment.
Figur 1 zeigt in einer Seitenansicht eine Stapelvorrichtung nach der Erfindung.Figure 1 shows a side view of a stacking device according to the invention.
Wege zur Ausführung der ErfindungWays of Carrying Out the Invention
Die in Figur 1 dargestellte Stapelvorrichtung dient zum Stapeln von kontinuierlich in Schuppenform angeförderten Papierbögen 1 , die in einer Querschneidemaschine hergestellt wurden. Die Bögen 1 werden dem Stapelbereich von einem als Bandförderer ausgebildeten Zuförderer 2 zugefördert, der vertikal ortsfest in einer Höhe oberhalb der maximalen Stapelhöhe über dem Boden angeordnet ist. Die Stapel 3 werden auf Paletten 4 gebildet, die auf einer Ablageplattform 5 liegen. Die Ablageplattform 5 ist auf die nachfolgend beschriebene Weise im Gestell der Stapelvorrichtung bis in den Bereich der Zuförderebene der Bögen 1 anhebbar und bis in den Flurbereich absenkbar aufgehängt: — ~The stacking device shown in FIG. 1 is used to stack sheets of paper 1 which are continuously conveyed in the form of scales and which have been produced in a cross-cutting machine. The sheets 1 are fed to the stacking area by a feed conveyor 2 designed as a belt conveyor, which is arranged vertically stationary at a height above the maximum stacking height above the floor. The stacks 3 are formed on pallets 4 which lie on a storage platform 5. The storage platform 5 can be raised in the frame of the stacking device in the manner described below up to the area of the feed plane of the sheets 1 and can be lowered into the corridor area: - ~
Das Gestell der Vorrichtung besteht aus zwei einlaufseitigen Ständern 6 und zwei auslaufseitigen Ständern 7, die außerhalb der Arbeitsbreite an beiden Maschinenlängsseiten angeordnet und an ihrem oberen Ende über Längsträger 8 und in Figur 1 nicht sichtbare Querträger miteinander verbunden sind. Die Ständer 6, 7 begrenzen den Stapelbereich. An der Innenseite jedes einlaufseitigen Ständers 6 ist ein Kragträger 9 vertikal bewegbar gelagert, der aus einem horizontal frei in den Stapelbereich kragenden Tragteil 10 und einem senkrecht nach oben abgewinkelten Lagerteil 1 1 besteht. Bevorzugt wird jeder Kragträger 9 einstückig aus einem abgewinkelten Blech von ca.The frame of the device consists of two inlet-side stands 6 and two outlet-side stands 7, which are arranged outside the working width on both longitudinal sides of the machine and are connected to one another at their upper end via longitudinal members 8 and cross members which are not visible in FIG. The stands 6, 7 limit the stacking area. On the inside of each upright stand 6, a cantilever 9 is vertically movable, which consists of a horizontally freely cantilevered in the stacking portion 10 and a vertically angled bearing part 1 1. Each cantilever 9 is preferably made in one piece from an angled sheet of approximately
40 mm Dicke mit ca. 400 mm Schenkelhöhe gebildet, das ausreichend stabil ist, um ein Stapelgewicht von mehreren Tonnen zu tragen. Die Ablageplattform 5 ist an den beiden waagerechten Tragteilen 1 0 der Kragträger 9 befestigt. Sie enthält eine ebene Auflagefläche, auf die die Paletten 4 aufgelegt werden können.40 mm thick with about 400 mm leg height, which is sufficiently stable to support a stack weight of several tons. The storage platform 5 is attached to the two horizontal support parts 1 0 of the cantilever 9. It contains a flat support surface on which the pallets 4 can be placed.
Der Lagerteil 1 1 des Kragträgers 9 ist in dem zugehörigen einlaufseitigen Ständer 6 in einer vertikalen Linearführung kippsicher gelagert. Der Lagerteil 1 1 ist mit einem ebenfalls an einem einlaufseitigen Ständer 6 befestigten Hebeantrieb verbunden, so daß der Tragteil 10 jedes Kragträgers 9 mit der daran befestigten Ablageplattform 5 bis in die Zuförderebene der Bögen 1 angehoben und bis in den Flurbereich abgesenkt werden kann. Der Hebeantrieb enthält einen Elektromotor 1 2, bevorzugt ein Servomotor, der eine sich quer über die Arbeitsbreite im oberen Querträger erstrek- kende Synchronwelle 1 3 antreibt. Die Synchronwelle 1 3 ist mit ausreichendem Abstand oberhalb der Zuförderebene angeordnet und mit ihren Enden jeweils in einem Ständer 6 gelagert. An jedem Ende der Synchronwelle 1 3 ist ein Kettenrad 14 befestigt, in das eine Zugkette 1 5 eingehängt ist. Die Zugkette 1 5 ist mit einem Ende an dem Lagerteil 1 1 des Kragträgers 9 befestigt, das andere Ende hängt, von einem Gewicht 1 6 beschwert, frei nach unten. Die Führung der beiden die Kragträger 9 haltenden Zugketten 1 5 um die über die Synchronwelle 1 3 miteinander verbundenen Kettenräder 14 gewährleistet, daß die Ablageplattform 5 in exakt waagerechter Lage von den Zugketten 1 6 mittels des Motors 1 5 angehoben und abgesenkt wird.The bearing part 1 1 of the cantilever 9 is mounted in the associated inlet-side stand 6 in a vertical linear guide against tilting. The bearing part 1 1 is connected to a lifting drive also attached to an upstream stand 6, so that the supporting part 10 of each cantilever 9 with the storage platform 5 attached to it can be raised into the feed plane of the arches 1 and lowered into the corridor area. The lifting drive contains an electric motor 1 2, preferably a servo motor, which drives a synchronous shaft 1 3 extending across the working width in the upper cross member. The synchronous shaft 1 3 is arranged at a sufficient distance above the feed plane and is supported with its ends in a stand 6. At each end of the synchronous shaft 1 3, a sprocket 14 is attached, in which a pull chain 1 5 is suspended. The pull chain 1 5 is attached at one end to the bearing part 1 1 of the cantilever 9, the other end hanging, weighted by a weight 1 6, freely downwards. The guidance of the two pull chains 1 5 holding the cantilever beams 9 around the sprockets 14 connected to one another via the synchronous shaft 1 3 ensures that the storage platform 5 is raised and lowered in an exactly horizontal position by the pull chains 1 6 by means of the motor 1 5.
Da sowohl die Kragträger 9 als auch ihr Hebeantrieb (Motor 1 2, Synchronwelle 1 3, Kettenräder 1 4) und die zugehörige Elektrik in den einlaufseitigen Ständern 6 gelagert sind, kann die Vorrichtung einfach auf verschiedene Einsatzfälle sowohl in ihrer Länge als auch in ihrer Breite angepaßt werden. Bei einer Breitenänderung brauchen nur die - 4 -Since both the cantilever 9 and its lifting drive (motor 1 2, synchronous shaft 1 3, sprockets 1 4) and the associated electrics are stored in the uprights 6, the device can easily be used for various applications in both its length and its width be adjusted. When changing the width only need - 4 -
Querträger und die Synchronwelie 1 3 in ihrer Länge angepaßt werden, bei einer Längenänderung die Länge des Tragarms 10, der Ablageplattform 5 und der Längsträger 8. Alle Antriebe, einschließlich des Hebeantriebs der Ablageplattform 5 und die zugehörige Elektrik sind in den beiden einlaufseitigen Ständern 6 angeordnet. Sie können daher vor der Endmontage, also dem Zusammenbau der Vorrichtung an ihrem Einsatzort, auf ihre Funktionsfähigkeit geprüft werden. Dies verkürzt die erforderliche Montagezeit am Einsatzort erheblich.Cross members and the synchronous shaft 1 3 are adjusted in length, in the event of a change in length, the length of the support arm 10, the storage platform 5 and the longitudinal beam 8. All drives, including the lifting drive of the storage platform 5 and the associated electronics are arranged in the two uprights 6 . They can therefore be checked for functionality before final assembly, i.e. assembly of the device at its place of use. This considerably shortens the installation time required on site.
Im Bereich der Zuförderebene der Bögen 1 und im Bereich der Stapeloberkante sind die bekannten Elemente für ein störungsfreies Fördern der Bögen 1 in den Stapelbereich und deren kantengenaue Ablage auf den Stapel 3 angeordnet:In the area of the feed plane of the sheets 1 and in the area of the top edge of the stack, the known elements for a trouble-free feeding of the sheets 1 into the stack area and their edge-accurate placement on the stack 3 are arranged:
Unmittelbar oberhalb der Zuförderebene sind mehrere sich in Transportrichtung über den Stapelbereich erstreckende Oberbänder 1 8 mit Abstand voneinander angeordnet, von denen die Bögen 1 beim Ablegen auf den Stapel 3 geführt werden. Die Vorderkanten der Bögen 1 werden von vertikalen Anschlagbrettern 1 9 ausgerichtet, die am Ende des Stapels 3 angeordnet sind. Seitlich werden die Bögen 1 von Schüttelblechen 20 geführt und ausgerichtet. Im Bereich vor den Anschlagbrettern 1 9 unterstützen mehrere Blasrohre 21 das Ablösen der Bögen 1 von den Oberbändern 1 8 durchImmediately above the feed level, a plurality of upper belts 1 8 extending in the transport direction over the stack area are arranged at a distance from one another, from which the sheets 1 are guided onto the stack 3 when they are deposited. The front edges of the sheets 1 are aligned by vertical stop boards 1 9, which are arranged at the end of the stack 3. The sheets 1 are guided and aligned laterally by shaking plates 20. In the area in front of the bulletin boards 1 9, several blowpipes 21 support the detachment of the sheets 1 from the upper bands 1 8
Druckluft, die von oben bläst und zugleich die Bögen 1 für eine störungsfreie Ablage auf dem Stapel 3 stabilisiert. Die auslaufseitigen Umlenkrollen 22 der Oberbänder 1 8, die Anschlagbretter 1 9 und die Blasrohre 21 sind in einem in und gegen Bogenlauf- richtung verstellbaren Wagen 23 gelagert, um ihre Position verschiedenen Bogenlän- gen anpassen zu können.Compressed air that blows from above and at the same time stabilizes the sheets 1 for trouble-free storage on the stack 3. The outlet-side deflection rollers 22 of the upper belts 1 8, the stop boards 1 9 and the blowpipes 21 are mounted in a carriage 23 which can be adjusted in and against the direction of sheet travel in order to be able to adapt their position to different sheet lengths.
Damit die Bogenzufuhr bei einem Stapelwechsel nicht unterbrochen werden muß, ist unterhalb des Bandförderers 2 eine Hilfstapelplattform 24 horizontal in den Stapelbereich einfahrbar gelagert, auf der die Bögen 1 zwischengestapelt werden, während ein fertiger Stapel 3 abtransportiert wird. Zum Antransport von leeren Paletten 4 und zumSo that the sheet supply does not have to be interrupted when changing stacks, an auxiliary stacking platform 24 is horizontally mounted in the stacking area below the belt conveyor 2, on which the sheets 1 are stacked while a finished stack 3 is being transported away. For transporting empty pallets 4 and
Abtransport von Paletten 4 mit fertigen Stapeln 3 dient ein Flurförderer 25, dessen Förderstrecke den Stapelbereich und zusätzlich jeweils etwa die gleiche Fläche vor und hinter den Stapelbereich abdeckt. Pallet 4 with finished stacks 3 is transported away by a floor conveyor 25, the conveying path of which covers the stacking area and additionally approximately the same area in front of and behind the stacking area.
