Abstract

The device (1) has a horizontally and vertically movable table (2) with a front transverse side facing towards total stacks (31, 32). Two identical, horizontal and drivable rollers (12, 13) are mounted on the transverse side, such that the rollers and the table are retracted between the partial stacks and remaining stacks. Longitudinal middle axes (28, 29) of the respective rollers are arranged at an angle that is not equal to 180 degree. Outer regions of the rollers are respectively arranged before inner regions in a retraction direction (A).

Description

Die Erfindung betrifft eine Vorrichtung zum Abnehmen mindestens eines Teilstapels aus blattförmigem Gut von mindestens einem Gesamtstapel, mit einem horizontal verfahrbaren Tisch, in dem, auf dessen dem mindestens einen Gesamtstapel zugewandten Seite, mindestens eine horizontal angeordnete, antreibbare Walze gelagert ist, zum Einfahren von Walze und Tisch zwischen den Teilstapel und den verbleibenden Reststapel.The invention relates to a device for removing at least one sub-stack of sheet-like material of at least one total stack, with a horizontally movable table, in which, on which the at least one total stack facing side, at least one horizontally arranged, drivable roller is mounted, for retracting the roller and table between the partial stack and the remaining residue.

In großer Größe vorliegende Gesamtstapel sind, um sie der Weiterverarbeitung zuzuführen, in aller Regel in Teilstapel zu unterteilen und hierbei die Teilstapel sukzessive der Weiterbearbeitung zuzuführen. Bei dem blattförmigen Gut handelt es sich beispielsweise um Blätter aus Papier, Pappe, Kunststofffolie und dergleichen. Die einzelnen Blätter können bedruckt oder unbedruckt sein.In large size present total stacks are, in order to supply them to further processing, usually subdivide into sub-stacks and in this case gradually supply the partial stacks for further processing. The sheet-like material is, for example, sheets of paper, cardboard, plastic film and the like. The individual sheets can be printed or unprinted.

Die Teilstapel werden beispielsweise einer Weiterverarbeitungsstation zugeführt, die als Rütteltisch ausgebildet ist. Dort werden die einzelnen Teilstapel abgelegt und durch Neigen des mit Seitenlinealen versehenen Tisches kantengenau an den Seitenlinealen ausgerichtet. Nach dem Ausrichten eines Teilstapels wird ein anschließend entsprechend vom Reststapel abgenommener Teilstapel dem Rütteltisch zugeführt und gleichfalls dieser Teilstapel, somit die Gesamtanordnung beider Teilstapel ausgerichtet. Anschließend werden diese Teilstapel und gegebenenfalls weitere Teilstapel einer Weiterverarbeitung zugeführt, beispielsweise einer Schneidmaschine.The partial stacks are supplied for example to a further processing station, which is designed as a vibrating table. There, the individual sub-stacks are stored and aligned by tilting the side rulers table provided edge-to-edge on the side rulers. After aligning a partial stack, a partial stack subsequently removed correspondingly from the remaining stack is fed to the vibrating table and likewise this partial stack, thus aligning the overall arrangement of both partial stacks. Subsequently, these partial stacks and possibly further partial stacks are sent for further processing, for example a cutting machine.

Der jeweilige Teilstapel wird vom Gesamtstapel abgenommen und hierbei der Tisch horizontal in den zwischen Teilstapel und Reststapel gebildeten Spalt eingefahren. Die im Tisch gelagerte Walze, die antreibbar ist, dient dem Auffächern des blattförmigen Guts beim Abnehmen des Teilstapels und auch dem Fördern des Teilstapels auf den Tisch, unabhängig von dessen Einfahrbewegung in den zwischen dem Teilstapel und dem Reststapel gebildeten Spalt. Vorzugsweise wird die Drehrichtung der Walze, bei Kontakt der Walze mit der Unterseite des Teilstapels, so gewählt, dass das unterste Blatt des Teilstapels entgegen der Einfahrrichtung des Tisches gezogen wird. Hierdurch wird eine Stauchung der untersten Blätter des Teilstapels vermieden. Dies ist unter dem Aspekt der exakten Übergabe des Teilstapels auf den Tisch von Vorteil.The respective partial stack is removed from the total stack and in this case the table is retracted horizontally into the gap formed between the partial stack and the remaining stack. The mounted in the table roller, which is driven, serves to fan the sheet-like Guts when removing the sub-stack and also conveying the sub-stack on the table, regardless of its retraction in the gap formed between the part-stack and the remaining stack. Preferably, the direction of rotation of the roller, upon contact of the roller with the bottom of the sub-stack, chosen so that the bottom sheet of the sub-stack is pulled against the direction of retraction of the table. As a result, compression of the lowermost sheets of the sub-stack is avoided. This is advantageous in terms of the exact transfer of the sub-stack to the table.

Eine Vorrichtung der eingangs genannten Art ist aus der DE 36 12 780 A1 bekannt. Mit dieser kann nur ein Teilstapel beim Verfahren des Tisches vom Gesamtstapel abgenommen werden. Es ist der Tisch mit einer einzigen horizontal angeordneten, antreibbaren Walze versehen. Der Tisch wird unterhalb des Teilstapels in den Gesamtstapel eingefahren, wobei der Teilstapel auf den Tisch aufläuft. Dieses Auflaufen wird durch die Walze erleichtert. Das Eindringen der Walze wird dadurch begünstigt, dass der Gesamtstapel etwas schräg gestellt wird, nämlich so, dass ein vorderer Eckbereich des Gesamtstapels, an dem der Teilstapel mittels einer separaten Einrichtung angehoben wurde, näher bei der Walze liegt als die diesem Eckbereich abgewandte Eckbereich des Gesamtstapels.A device of the type mentioned is from the DE 36 12 780 A1 known. With this only a partial stack can be removed when moving the table from the total pile. It is the table with a single horizontally arranged, drivable roller provided. The table is retracted below the sub-stack in the total stack, with the part pile runs onto the table. This emergence is facilitated by the roller. The penetration of the roll is facilitated by the fact that the total stack is slightly inclined, namely, such that a front corner region of the overall stack, on which the partial stack has been raised by means of a separate device, is closer to the roll than the corner region of the overall stack facing away from this corner region ,

Eine Vorrichtung zum Abnehmen jeweils eines einzigen Teilstapels aus blattförmigem Gut von einem Gesamtstapel bei einer horizontalen Verfahrbewegung eines Tisches ist ferner aus der DE 39 33 626 C1 bekannt. Die CH 538 982 A offenbart eine Vorrichtung gemäß dem Oberbegriff des Anspruchs 1.A device for removing in each case a single sub-stack of sheet-like material from a total stack in a horizontal movement of a table is further from the DE 39 33 626 C1 known. The CH 538 982 A discloses a device according to the preamble of claim 1.

In der Praxis sind Gesamtstapel in unterschiedlichster Größe einer Weiterverarbeitung zuzuführen. Es handelt sich einerseits um relativ große Gesamtstapel, wobei eine Palette nur einen Gesamtstapel aufnimmt, andererseits um relativ kleinere Gesamtstapel, wobei mehrere, insbesondere zwei Gesamtstapel dicht an dicht auf einer gemeinsamen Palette bzw. einer gemeinsam handhabbaren, aus zwei Paletten gebildeten Palettenanordnung gelagert sind. Es sind sogenannte Twin-Paletten bekannt. Hierunter wird eine Doppelpalette verstanden, wobei die jeweilige der beiden identischen Paletten eine Länge von 67 cm und eine Breite von 49 cm aufweist Beide Paletten werden, nebeneinander angeordnet, mittels Verbindungsmitteln miteinander verbunden, beispielsweise mittels eines Kunststoffbandes oder durch Zusammentackern der beiden Paletten. Es ergibt sich hierdurch ein Gesamtmaß der Doppelpalette von 67 cm x 98 cm. Auf der Doppelpalette finden zwei Gesamtstapel Platz, die im Wesentlichen die Aufnahmefläche der Twin-Palette einnehmen.In practice, total stacks of different sizes are to be sent for further processing. On the one hand, these are relatively large total stacks, one pallet accommodating only one total stack, and, on the other hand, relatively smaller total stacks, several, in particular two, total stacks being mounted close together on a common pallet or a pallet arrangement formed from two pallets. There are so-called twin-pallets known. This is understood to mean a double pallet, with the respective two identical pallets having a length of 67 cm and a width of 49 cm. Both pallets are arranged side by side, connected to one another by means of connecting means, for example by means of a plastic band or by collapsing the two pallets. This results in a total dimension of the double pallet of 67 cm x 98 cm. The double pallet accommodates two total stacks, which essentially occupy the receiving area of the twin pallet.

Mit den aus dem vorstehend diskutierten Stand der Technik bekannten Vorrichtungen ist ein gleichzeitiges Abnehmen der oberen Teilstapel bei mehreren, insbesondere zwei nebeneinander angeordneten Gesamtstapeln nicht möglich. Zumindest bedarf es hierfür separater Mittel, die eine Vortrennung der Teilstapel und der Reststapel herbeiführen, beispielsweise Keile, die zwischen die Teilstapel und die Reststapel eingefahren werden. Dies bedingt einen erheblichen zusätzlichen Bauaufwand hinsichtlich der Gestaltung der Vorrichtung zum Abnehmen der Teilstapel.With the devices known from the prior art discussed above, simultaneous removal of the upper part stacks is not possible with several, in particular two juxtaposed, total stacks. At the very least, this requires separate means which bring about a pre-separation of the partial stacks and the remaining stacks, for example wedges, which are inserted between the partial stacks and the remaining stacks. This requires a considerable additional construction costs with regard to the design of the device for removing the partial stacks.

Aufgabe der vorliegenden Erfindung ist es, eine Vorrichtung der eingangs genannten Art so weiter zu bilden, dass mit dieser, bei Anordnung einer einzigen Palette und auf dieser aufliegendem Gesamtstapel, ein Teilstapel abgenommen werden kann, oder, bei Anordnung zweier nebeneinander angeordneter Paletten, in einem Arbeitsgang von den auf diesen aufliegenden beiden Gesamtstapeln, gleichzeitig zwei Teilstapel abgenommen werden können.Object of the present invention is to provide a device of the type mentioned so that with this, with the arrangement of a single pallet and on this resting total stack, a partial stack can be removed, or, in the arrangement of two juxtaposed pallets, in one Operation of the resting on these two total stacks, two partial stacks can be removed simultaneously.

Gelöst wird die Aufgabe bei einer Vorrichtung der eingangs genannten Art dadurch, dass im Tisch zwei Walzen gelagert sind, deren Drehachsen unter einem Winkel ungleich 180° angeordnet sind, wobei die äußeren Bereiche der Walzen in Einfahrrichtung des Tisches vor den inneren Bereichen der Walzen angeordnet sind.The object is achieved in a device of the type mentioned above in that two rollers are mounted in the table whose axes of rotation are arranged at an angle not equal to 180 °, wherein the outer regions of the rollers are arranged in the retraction of the table in front of the inner regions of the rollers ,

Sind von zwei Gesamtstapeln gleichzeitig Teilstapel abzunehmen, kann dies durch die erfindungsgemäße Vorrichtung auf einfache Art und Weise dadurch bewerkstelligt werden, weil jede Walze nicht parallel bezüglich der Drehachse dieser Walze und der dieser Walze zugewandten Fläche des Gesamtstapels auf diesen auftrifft, somit den Gesamtstapel anfangs nur eine vertikale Stapelkante kontaktiert. Diese Kontaktierung, quasi entlang einer vertikalen Linie, bewirkt ein Auffächern des Gesamtstapels bereits ohne zusätzliche Hilfsmittel zum Trennen von der jeweiligen Walze zugeordneten Teilstapel und Gesamtstapel. Durch Antreiben der Walze, insbesondere derart, dass diese mit der Unterseite des zugeordneten Teilstapels in Kontakt gelangt, bei einer Drehrichtung der Walze derart, dass das unterste Blatt des Teilstapels entgegen der Einfahrrichtung der Walze bzw. des Tisches gezogen wird, wird sichergestellt, dass die Walze das Abnehmen des Teilstapels vom Gesamtstapel nachhaltig unterstützt, und bei Überlagerung der Einfahrbewegung des Tisches in den Spalt zwischen Teilstapel und Gesamtstapel der Teilstapel vom Reststapel abgenommen und auf den Tisch gefördert wird. In diesem Zusammenhang können dann, wenn der Teilstapel zumindest im Einfachbereich des Tisches in den Gesamtstapel vom Reststapel getrennt ist, zusätzliche Mittel vorgesehen sein, die den Teilstapel ergreifen, so dass diese Mittel das Überführen des Teilstapels auf den Tisch unterstützen. So ist vorzugsweise im Bereich jeder Walze eine Greifeinrichtung zum Ergreifen des Teilstapels hinter der Walze vorgesehen.If partial stacks are to be taken from two stacks at a time, this can be achieved in a simple manner by the device according to the invention, since each roller does not impinge on it parallel to the axis of rotation of this roller and the surface of the total stack facing this roller, thus initially only stacks the total stack contacted a vertical stacking edge. This contacting, virtually along a vertical line, causes a fanning of the entire stack already without additional aids for separating part of the stack and the total stack associated with the respective roller. By driving the roller, in particular such that it comes into contact with the underside of the associated sub-stack, in a direction of rotation of the Roller such that the lowermost sheet of the sub-stack is pulled against the direction of retraction of the roller or the table, it is ensured that the roller sustainably supports the removal of the sub-stack of the total stack, and superimposed on the retraction of the table in the gap between the partial stack and total stack the partial stack is removed from the remaining stack and conveyed to the table. In this context, if the partial stack is separated from the remaining stack in the total stack at least in the single region of the table, additional means may be provided which grip the partial stack, so that these means support the transfer of the partial stack to the table. Thus, a gripping device for gripping the partial stack behind the roller is preferably provided in the region of each roller.

Sind mittels der Vorrichtung nicht zwei Gesamtstapel gleichzeitig zu handhaben, sondern nur ein Gesamtstapel, wird die Palette mit dem darauf ruhenden Gesamtstapel so bezüglich der Walzen positioniert, dass der Gesamtstapel im Bereich einer dem Tisch zugewandten vertikalen Kante des Gesamtstapels einem der beiden Walzen zugewandt ist, somit diese eine Walze nicht parallel zur dieser zugewandten Fläche des Gesamtstapels angeordnet ist. Die zweite Walze besitzt somit keine anfängliche Auffächerfunktion, sondern gelangt erst später in den Spalt zwischen Teilstapel und Reststapel, wenn dieser bereits durch die erstgenannte Walze gebildet ist.If by means of the device not two total stacks are to be handled at the same time, but only one total stack, the pallet with the total stack resting thereon is positioned relative to the rolls such that the total stack faces one of the two rolls in the region of a vertical edge of the total stack facing the table, Thus, this one roller is not arranged parallel to this facing surface of the overall stack. The second roller thus has no initial Auffächerfunktion, but only later reaches the gap between the partial stack and the remaining stack, if this is already formed by the former roller.

Wesentlich ist somit bei einer Handhabung eines einzigen Gesamtstapels bzw. zweier benachbart angeordneter Gesamtstapel, dass die Palette, auf der der eine Gesamtstapel ruht bzw. die beiden Gesamtstapel ruhen, exakt bezüglich der Walzenanordnung der Vorrichtung ausgerichtet wird bzw. werden. Dies kann einfach dadurch erfolgen, dass die Vorrichtung einen Bodenanschlag für die Palette aufweist. Dieser Bodenanschlag sollte in unterschiedlichen Schwenkpositionen anordbar sein, derart, dass die am Bodenanschlag ausgerichtete Palette mit deren der jeweiligen Walze zugewandten Seite unter einem Winkel von 2 bis 10°, insbesondere 2 bis 5°, zur Drehachse dieser Walze positioniert ist. Hierdurch ist immer sichergestellt, dass die jeweilige Walze, sei es die eine Walze beim Abnehmen eines Teilstapels von einem großen Gesamtstapel, oder beim Abnehmen zweier Teilstapeln von zwei kleineren Gesamtstapeln, immer den Gesamtstapel im Bereich einer vertikalen Kante, die der Walze zugewandt ist, anfänglich kontaktiert. Insbesondere ist der verstellbare Bodenanschlag in einem Winkelbereich von 0° bis 10°, vorzugsweise 0° bis 5° bezüglich der Senkrechten zur Mittellängsachse bzw. der Senkrechten zur Verfahrrichtung des Tisches verstellbar.It is essential when handling a single total stack or two juxtaposed total stack that the pallet on which rests a total stack or rest the two total stack is exactly aligned with respect to the roller assembly of the device or will. This can be done simply by the device having a bottom stop for the pallet. This bottom stop should be able to be arranged in different pivoting positions, such that the pallet aligned with the bottom stop is positioned with its side facing the respective roller at an angle of 2 to 10 °, in particular 2 to 5 °, to the axis of rotation of this roller. This always ensures that the respective roller, be it when removing one sub-stack from a large total stack, or when removing two sub-stacks from two smaller total stacks, one roll initially contacts the entire stack in the area of a vertical edge facing the roll. In particular, the adjustable bottom stop is adjustable in an angle range of 0 ° to 10 °, preferably 0 ° to 5 ° with respect to the perpendicular to the central longitudinal axis or the perpendicular to the direction of travel of the table.

Besonders gute Ergebnisse beim Abnehmen des mindestens einen Teilstapels vom mindestens einem Gesamtstapel lassen sich erzielen, wenn die Drehachse der jeweiligen Walze mit der Einfahrrichtung des Tisches, bezogen auf den mittleren Bereich des Tisches in seinem dem Gesamtstapel zugewandten Bereich, einen Winkel von 88° bis 80°, insbesondere 88° bis 85° einschließt.Particularly good results when removing the at least one sub-stack of at least one total stack can be achieved if the axis of rotation of the respective roller with the retraction of the table, based on the central region of the table in its total stack facing area, an angle of 88 ° to 80 °, in particular 88 ° to 85 °.

Von besonderem Vorteil ist ferner, wenn die Walzen symmetrisch zur Einfahrrichtung des Tisches, insbesondere symmetrisch zur Längsmittelachse des Tisches angeordnet sind. Sind Teilstapel von zwei Gesamtstapeln gleichzeitig zu entnehmen, wird vorzugsweise die den beiden Walzen zugewandte vertikale Stirnfläche der Gesamtstapel senkrecht zur Verfahrrichtung des Tisches positioniert, somit die Palette entsprechend am Bodenanschlag ausgerichtet. Ist nur ein Teilstapel von einem größeren Gesamtstapel abzunehmen, wird diese vertikale Stirnseite des Gesamtstapels unter einem Winkel ungleich 90° bezüglich der Verfahrrichtung des Tisches angeordnet, wobei dieser Winkel so zu wählen ist, dass erst dann, wenn der vorlaufende Bereich der einen Walze in den Gesamtstapel eingefahren ist, der vorlaufende Bereich der anderen Walze den Gesamtstapel kontaktiert. Durch diese Art des Einfahrens der Walzen in den Gesamtstapel wird erreicht, dass die untere Blattlage des abgenommenen Teilstapels bei entsprechender Drehrichtung der Walzen straff gezogen wird, welches für die weitere Verarbeitung des Teilstapels unter dem Aspekt eines exakten Ablegens des Teilstapels auf dem Tisch von Bedeutung ist.It is also particularly advantageous if the rollers are arranged symmetrically to the retraction direction of the table, in particular symmetrically to the longitudinal center axis of the table. If partial stacks of two total stacks can be taken at the same time, the vertical end face of the total stacks facing the two rolls is preferably positioned perpendicular to the direction of travel of the table, thus aligning the pallet accordingly with the bottom stop. If only a partial stack to remove from a larger total stack, this vertical end face of the total stack is arranged at an angle not equal to 90 ° with respect to the direction of travel of the table, this angle is to be chosen so that only when the leading portion of a roller in the Total stack is retracted, the leading portion of the other roller contacted the entire stack. This type of retraction of the rolls in the overall stack ensures that the lower sheet layer of the removed part stack is pulled taut with a corresponding direction of rotation of the rolls, which is important for the further processing of the sub-stack under the aspect of an exact placement of the sub-stack on the table ,

Der Tisch weist insbesondere eine rechteckige Aufnahmefläche für den Teilstapel auf und die beiden Walzen sind unterhalb des Niveaus der Aufnahmefläche, vor dem Tisch, bezogen auf dessen Einfahrrichtung, angeordnet.In particular, the table has a rectangular receiving surface for the partial stack and the two rollers are arranged below the level of the receiving surface, in front of the table, with respect to its direction of retraction.

Eine bauliche besonders einfache Gestaltung und optimale Funktionalität der Vorrichtung ergibt sich, wenn die jeweilige Walze über ihre Länge einen konstanten Außendurchmesser aufweist. Obwohl die jeweilige Walze in Einführrichtung schräg zum Gesamtstapel angeordnet ist, ist hierdurch eine präzise Krafteinleitung der Reibkräfte zwischen Walze und Teilstapel gewährleistet. Insbesondere ist vorgesehen, dass die beiden Walzen identisch gestaltet sind. Besonders gute Auffächerergebnisse und optimale Reibwerte lassen sich erzielen, wenn die jeweilige Walze einen elastischen Mantelbereich aufweist.A structurally particularly simple design and optimal functionality of the device results when the respective roller has a constant outer diameter over its length. Although the respective roller is arranged obliquely to the total stack in the insertion direction, this ensures a precise introduction of force of the frictional forces between the roller and the partial stack. In particular, it is provided that the two rollers are designed identically. Particularly good fan results and optimum coefficients of friction can be achieved if the respective roller has an elastic jacket area.

Gemäß einer bevorzugten Weiterbildung der Erfindung ist vorgesehen, dass die beiden Walzen im Bereich deren benachbarten Enden gelenkig miteinander verbunden sind. Diese gelenkige Verbindung vereinfacht die Lagerung der Walzen und ermöglicht überdies diese besonders einfach mittels eines gemeinsamen Antriebs anzutreiben. Gemäß einer konkreten Weiterbildung ist vorgesehen, dass die beiden Walzen im Bereich deren benachbarten Enden mittels eines Doppelgelenks miteinander verbunden sind, wobei das Doppelgelenk drehbar in einem Träger gelagert ist, der im Tisch gelagert ist. In diesem Fall sind die beiden Walzen dreifach gelagert; einerseits im Bereich der benachbarten Enden mittels des Doppelgelenks, andererseits in deren einander abgewandten Bereichen. Bei diesen Bereichen handelt es sich insbesondere um die Seitenbereiche des Tisches. Insbesondere ist vorgesehen, dass die eine Walze im Bereich des der anderen Walze abgewandten Endes im Tisch drehbar gelagert ist und die andere Walze im Bereich des der einen Walze abgewandten Endes im Tisch drehbar gelagert ist oder in dem mit dem Tisch verbundenen Antrieb gelagert ist. Bei diesem Antrieb handelt es sich insbesondere um einen elektromotorischen Antrieb mit Untersetzungsgetriebe.According to a preferred embodiment of the invention, it is provided that the two rollers are hinged together in the region of their adjacent ends. This articulated connection simplifies the storage of the rollers and also makes it particularly easy to drive them by means of a common drive. According to a specific embodiment, it is provided that the two rollers are connected to each other in the region of their adjacent ends by means of a double joint, wherein the double joint is rotatably mounted in a carrier which is mounted in the table. In this case, the two rolls are stored in triplicate; on the one hand in the region of the adjacent ends by means of the double joint, on the other hand in their mutually remote areas. These areas are in particular the side areas of the table. In particular, it is provided that one roller is rotatably mounted in the table in the area facing away from the other roller and the other roller is rotatably mounted in the table in the region of the one end facing away from the roller or is mounted in the drive connected to the table. This drive is in particular an electric motor drive with reduction gear.

Die Figuren 1 bis 12 veranschaulichen den Aufbau der erfindungsgemäßen Vorrichtung 1 in stark vereinfachter Darstellung. Die Vorrichtung weist einen horizontal und auch vertikal verfahrbaren Tisch 2 auf. Der Tisch 2 ist horizontal in einem Gestell 3 verfahrbar gelagert und das Gestell 3 vertikal in einem auf dem Boden stehenden Ständer 4 verfahrbar gelagert. Hierdurch lässt sich die beschriebene Verfahrbewegung des Tisches 2 erzielen.The FIGS. 1 to 12 illustrate the structure of the device 1 according to the invention in a highly simplified representation. The device has a horizontally and vertically movable table 2. The table 2 is mounted horizontally movable in a frame 3 and the frame 3 vertically in one the stand 4 standing on the floor. As a result, the described movement of the table 2 can be achieved.

Der Tisch 2 weist eine im rechteckige obere Aufnahmefläche 5 auf. Diese ist durch zwei parallel zueinander angeordnete Längsseiten 6 und eine senkrecht zu diesen angeordnete hintere Querseite 7 sowie eine parallel zur Querseite 7 angeordnete vordere Querseite 8, wie es der Figur 13 zu entnehmen ist, gebildet.The table 2 has a rectangular upper receiving surface 5. This is by two mutually parallel longitudinal sides 6 and arranged perpendicular to these rear transverse side 7 and a parallel to the transverse side 7 arranged front transverse side 8, as it FIG. 13 can be seen formed.

Wie es der Figur 13 ferner zu entnehmen ist, ist der Tisch 2 im Bereich seiner Aufnahmefläche 5 mit einer Vielzahl von Luftauslassdüsen 9 versehen, die zum einfachen Verschieben eines Blattgutstapels auf dem Tisch 2 vorgesehen sind und ein Luftpolster zwischen dem Stapel und dem Tisch bilden. Die Luftauslassdüsen 9 sind in bekannter Art und Weise mittels Kugeln verschließbar und nur dann geöffnet, wenn ein Stapel im Bereich der jeweiligen Luftauslassdüse 9 auf dem Tisch 2 aufliegt und die Kugel aus deren Dichtstellung zurück drückt.Like the FIG. 13 it can also be seen, the table 2 is provided in the region of its receiving surface 5 with a plurality of Luftauslassdüsen 9, which are provided for easy movement of a sheet stack on the table 2 and form an air cushion between the stack and the table. The air outlet nozzles 9 are closed in a known manner by means of balls and only open when a stack in the region of the respective Luftauslassdüse 9 rests on the table 2 and pushes the ball from the sealing position back.

Wie der Figur 13 weiter zu entnehmen ist, ist mit dem Tisch 2, im Bereich dessen der vorderen Querseite 8 zugewandten Endes, eine Leiste 10 verbunden, die einerseits der mittigen Lagerung einer noch näher zu beschreibenden Walzenanordnung 11 in einem mittleren Bereich der Walzenanordnung 11, somit im Bereich der halben Breite des Tisches 2 dient, andererseits den aufgrund der besonderen Anordnung der Walzenanordnung 11 zwischen dieser und dem Tisch 2 gebildeten, nicht rechteckförmigen Spalt überbrückt. Diese Walzenanordnung 11 weist zwei identische Walzen 12 und 13 auf. Die jeweilige Walze ist zylindrisch ausgebildet und weist über ihre gesamte Länge einen konstanten Außendurchmesser auf. Die jeweilige Walze besitzt einen nicht näher veranschaulichten elastischen Mantelbereich.Again FIG. 13 can be seen further, is connected to the table 2, in the region of the front transverse side 8 facing end, a bar 10, on the one hand the central storage of a still closer to described roller assembly 11 in a central region of the roller assembly 11, thus in the field half width of the table 2 serves, on the other hand bridged due to the particular arrangement of the roller assembly 11 formed between this and the table 2, not rectangular gap. This roller assembly 11 has two identical rollers 12 and 13. The respective roller is cylindrical and has a constant outer diameter over its entire length. The respective roller has a non-illustrated elastic jacket region.

Der Figur 14 ist zu entnehmen, dass die beiden Walzen 12 und 13 im Bereich deren benachbarten Enden gelenkig miteinander verbunden sind. Diese Verbindung erfolgt mittels eines Doppelgelenks 14. Dieses weist einen zentralen Gelenkkörper 15 und zwei gelenkig mit diesem verbundene äußere Gelenkkörper 16 auf. Die Gelenkkörper 16 sind in stirnseitige Vertiefungen der beiden Walzen 12 und 13 eingesteckt und über Zapfen 17 die Gelenkkörper 15 bzw. 16 in Aufnahmebohrungen 18 der Walzen 12 bzw. 13 radial eingepasst. Die Walze 12 bzw. 13 und die Gelenkkörper 16 sind im Bereich der Linien 19 mit fluchtenden Bohrungen versehen, in die ein Stift eingesteckt ist, der der Übertragung des Drehmoments von der Walze 12 über das Doppelgelenk 14 in die Walze 13 dient. Der Gelenkkörper 15 ist axial festgelegt, aber frei drehbar in einer Gelenkaufnahme 20 gelagert, die Bestandteil eines Lagerteils 21 bildet, das, wie es der Darstellung der Figur 13 zu entnehmen ist, in der Leiste 10 und damit im Tisch 2 gelagert ist.Of the FIG. 14 It can be seen that the two rollers 12 and 13 are hinged together in the region of their adjacent ends. This connection is made by means of a double joint 14. This has a central Joint body 15 and two hingedly connected to this outer joint body 16. The hinge body 16 are inserted into the end-side recesses of the two rollers 12 and 13 and fitted via pins 17, the joint body 15 and 16 in receiving holes 18 of the rollers 12 and 13 radially. The roller 12 or 13 and the joint body 16 are provided in the region of the lines 19 with aligned bores in which a pin is inserted, which serves to transmit the torque from the roller 12 via the double joint 14 in the roller 13. The joint body 15 is fixed axially, but freely rotatably mounted in a joint receptacle 20 which forms part of a bearing part 21, which, as shown in the illustration of FIG. 13 can be seen in the bar 10 and thus stored in the table 2.

Der Figur 13 ist zu entnehmen, dass die Walze 12 im Bereich ihres dem Doppelgelenk 14 abgewandten Endes in einer dort mit dem Tisch 2 verbundenen Antriebseinheit 22 gelagert ist. Mittels dieser ist die Walze 12 antreibbar und über das Doppelgelenk 14 treibt die Walze 12 die Walze 13 an. Diese Walze 13 ist im Bereich ihres dem Doppelgelenk 14 abgewandten Endes frei drehbar in einer Lageraufnahme 23 gelagert, die ihrerseits in dem diesem Ende der Walze 3 zugewandten Bereich des Tisch 2 gelagert ist.Of the FIG. 13 It can be seen that the roller 12 is mounted in the region of its end facing away from the double joint 14 in a there connected to the table 2 drive unit 22. By means of this, the roller 12 can be driven and via the double joint 14, the roller 12 drives the roller 13 at. This roller 13 is freely rotatably mounted in the region of its end remote from the double joint 14 in a bearing receptacle 23, which in turn is mounted in the end of the roller 3 facing the area of the table 2.

Figur 15 veranschaulicht die Lagerung der Walze 12 in der Antriebseinheit 22. Die Antriebseinheit 22 weist einen Elektromotor 24 und ein Getriebe 25 auf, die mit einer Lagerplatte 26 verbunden sind, die am Tisch 2 angeflanscht ist. FIG. 15 illustrates the mounting of the roller 12 in the drive unit 22. The drive unit 22 has an electric motor 24 and a gear 25, which are connected to a bearing plate 26 which is flanged to the table 2.

Figur 16 veranschaulicht die Lagerung der Walze 13 im Bereich der Lageraufnahme 23. Diese ist gleichfalls in einer Lagerplatte 27 gelagert, die am Tisch 2 angeflanscht ist. FIG. 16 illustrates the storage of the roller 13 in the region of the bearing receptacle 23. This is also stored in a bearing plate 27 which is flanged to the table 2.

Den Figuren 13 bis 16 und auch der Figur 1 ist zu entnehmen, dass die Walzen 12 und 13 derart im Tisch 2 gelagert sind, dass die Längsmittelachse 28 der Walze 12 einen Winkel ungleich 180° mit der Längsmittelachse 29 der Walze 13 einschließt. Hierbei sind die äußeren Bereiche der Walzen 12 und 13, somit die Bereiche, die den Lagerplatten 26 und 27 zugewandt sind, weiter entfernt von der Querseite 8 des Tisches 2 als die Walzen 12 und 13 im Bereich des Doppelgelenks 14 vom Tisch 2 entfernt sind. Die beiden Längsmittelachsen 28 und 29 schließen einen Winkel von 176 bis 160°, insbesondere 176° bis 170° ein. Die Anordnung der Walzen 12 und 13 ist hierbei symmetrisch zur in Figur 13 verdeutlichten Längsmittelachse 30 des Tisches 2, bezüglich dessen auch seine Einfahrrichtung durch den Pfeil A, der in Richtung der Längsmittelachse 30 verläuft, veranschaulicht ist.The FIGS. 13 to 16 and also the FIG. 1 It can be seen that the rollers 12 and 13 are mounted in the table 2 such that the longitudinal central axis 28 of the roller 12 forms an angle not equal to 180 ° with the longitudinal center axis 29 of the roller 13. Here, the outer portions of the rollers 12 and 13, thus the areas facing the bearing plates 26 and 27 are farther away from the transverse side 8 of the table 2 than the rollers 12 and 13 in the region of the double joint 14 are remote from the table 2. The two longitudinal central axes 28 and 29 enclose an angle of 176 to 160 °, in particular 176 ° to 170 °. The arrangement of the rollers 12 and 13 is in this case symmetrical to in FIG. 13 clarified longitudinal central axis 30 of the table 2, with respect to its also its retraction direction by the arrow A, which extends in the direction of the longitudinal central axis 30, is illustrated.

Figur 1 verdeutlicht die erfindungsgemäße Vorrichtung 1 mit zwei identischen, im Bereich der Vorrichtung 1 angeordneten Gesamtstapeln 31 und 32, die jeweils quaderförmig ausgebildet sind und im Bereich benachbarter Längsseiten dicht an dicht angeordnet sind, so dass sie einen einzigen, doppelt so breiten Quader bilden. Die beiden Gesamtstapel 31 und 32 befinden sich auf einer in der gezeigten Draufsicht nicht sichtbaren Twin-Palette. Die beiden Gesamtstapel 31 und 32 sind exakt auf der Twin-Palette ausgerichtet, deren Aufnahmefläche im Wesentlichen der Aufstandsfläche der beiden Gesamtstapel 31 und 32 auf der Twin-Palette entspricht. Diese Twin-Palette ist exakt an einem verstellbaren Bodenanschlag 33 der Vorrichtung 1 ausgerichtet, wobei der Bodenanschlag senkrecht zur Längsmittelachse 30 des Tisches 2 und damit parallel zur Querseite 7 des Tisches 2 positioniert ist. Aufgrund der exakten Ausrichtung der Gesamtstapel 31 und 32 auf der Twin-Palette sind somit die dem Tisch 2 zugewandten Seiten 34 und 35 der Gesamtstapel 31 und 32 exakt vertikal und parallel zur Querseite 7 angeordnet. In der in Figur 1 dargestellten Ausgangssituation befindet sich die Vorrichtung 1 in deren Grundstellung, in der die beiden Walzen 12 und 13 in geringem Abstand zu den Gesarntstapeln 31 und 32 angeordnet ist, konkret die Walzen 12 und 13 im Bereich deren abgewandten Enden näher und in einem Winkel ungleich 0° zum Gesamtstapel 31 bzw. 32 angeordnet sind, als die dem Doppelgelenk 14 zugewandten Enden der Walzen 12 und 13. FIG. 1 illustrates the device 1 according to the invention with two identical, arranged in the region of the device 1 total stacks 31 and 32, which are each cuboid and are arranged close to each other in the region of adjacent longitudinal sides, so that they form a single, twice as wide cuboid. The two total stacks 31 and 32 are located on a not visible in the plan view twin-pallet. The two total stacks 31 and 32 are exactly aligned on the twin pallet whose receiving surface substantially corresponds to the footprint of the two total stacks 31 and 32 on the twin pallet. This twin pallet is exactly aligned with an adjustable bottom stop 33 of the device 1, wherein the bottom stop is positioned perpendicular to the longitudinal central axis 30 of the table 2 and thus parallel to the transverse side 7 of the table 2. Due to the exact alignment of the total stacks 31 and 32 on the twin pallet thus the table 2 facing sides 34 and 35 of the total stack 31 and 32 are arranged exactly vertical and parallel to the transverse side 7. In the in FIG. 1 illustrated initial situation, the device 1 is in its basic position, in which the two rollers 12 and 13 is arranged at a small distance to Gesarntstapeln 31 and 32, specifically the rollers 12 and 13 in the region of their opposite ends closer and at an angle not equal to 0 ° are arranged to the total stack 31 and 32, as the double joint 14 facing ends of the rollers 12 and 13th

Es wird dann der Tisch 2 auf ein Niveau verfahren, das soweit unter dem oberen Niveau von Gesamtstapel 31 bzw. Gesamtstapel 32 liegt, dass ein Teilstapel blättrigen Guts definierter Dicke, beispielsweise ein Teilstapel mit einer Dicke von 10 cm vom Gesamtstapel abgetrennt werden kann und damit jeweils ein Reststapel verbleibt. Zum Abnehmen der Teilstapel von den Gesamtstapeln 31 und 32 werden die Walzen 12 und 13 mittels der Antriebseinheit 22 angetrieben, derart, dass die Antriebseinheit 22 die Walzen 12 und 13 entgegen dem Uhrzeigersinn antreibt. Beim Verfahren des Tisches 2 in Richtung der beiden Gesamtstapel 31 und 32 kontaktieren die beiden Walzen 12 und 13 somit gleichzeitig die Gesamtstapel 31 und 32 im Bereich deren Kanten 36 und 37 und fächern beim weiteren Verfahren des Tisches 2 die Gesamtstapel 31 und 32, ausgehend von der jeweiligen Kante 36 bzw. 37 auf und gelangen beim weiteren Einfahren im Bereich des Doppelgelenks 14 in die beiden Gesamtstapel 31 und 32, dort wo diese aneinander liegen. Dieser Zustand ist in Figur 2 veranschaulicht.It is then the table 2 moved to a level that is so far below the upper level of total stack 31 or total stack 32, that a sub-stack of leafy Guts defined thickness, for example, a partial stack with a thickness of 10 cm from the total stack can be separated and thus one remaining stack remains. To remove the partial stacks from the total stacks 31 and 32, the rollers 12 and 13 are driven by means of the drive unit 22, such that the drive unit 22 drives the rollers 12 and 13 in the counterclockwise direction. In the process of the table 2 in the direction of the two total stacks 31 and 32, the two rollers 12 and 13 thus simultaneously contact the total stacks 31 and 32 in the region of their edges 36 and 37 and fan in the further process of the table 2, the total stack 31 and 32, starting from the respective edge 36 or 37 and reach the further retraction in the region of the double joint 14 in the two total stacks 31 and 32, where they are adjacent to each other. This condition is in FIG. 2 illustrated.

Nach diesem Auffächern fahren, wie in Figur 3 veranschaulicht, aufgrund des horizontalen Vorschubes des Tisches 2 die angetriebenen Walzen 12 und 13 weiter in den zwischen den Teilstapeln 38 und 39 und den unter diesen liegenden, nicht veranschaulichten Reststapeln gebildeten Spalt und es ergreifen Greifer 40 und 41, die über nicht gezeigte Mittel relativ zum Tisch 2 verfahrbar in der Vorrichtung 1 gelagert sind, die Teilstapel 38 und 39 im Bereich der Seiten 34 und 35. Dieser Zustand ist in Figur 3 veranschaulicht.After this fanning drive, as in FIG. 3 FIG. 12 illustrates, due to the horizontal advancement of the table 2, the driven rollers 12 and 13 moving further into the nip formed between the sub-stacks 38 and 39 and the underlying unillustrated stacks, and grippers 40 and 41 engage relative to the non-illustrated means Table 2 are movably mounted in the device 1, the sub-stacks 38 and 39 in the region of the sides 34 and 35. This state is in FIG. 3 illustrated.

Bei mittels der Greifer 40 und 41 fixierten Teilstapeln 38 und 39 fährt der Tisch 2 weiter vor, so dass die Walzen 12 und 13 im Bereich der den Seiten 34 und 35 abgewandten Seiten der Teilstapel 38 und 39 unter diesen herausfahren und die Teilstapel 38 und 39 vollständig auf den Tisch 2 abgelegt werden, bis auf den Bereich der Teilstapel 38 und 39, der mittels der Greifer 40 und 41 ergriffen ist. Dieser Zustand ist in Figur 4 veranschaulicht.When fixed by means of grippers 40 and 41 sub-stacks 38 and 39 continues the table 2, so that the rollers 12 and 13 in the region of the sides 34 and 35 opposite sides of the sub-stacks 38 and 39 ride out under these and the sub-stacks 38 and 39 are completely placed on the table 2, except for the area of the partial stacks 38 and 39 which is gripped by means of the grippers 40 and 41. This condition is in FIG. 4 illustrated.

Die Greifer 40 und 41 ziehen dann die beiden Teilstapel 38 und 39 bis zu dem den Walzen 12 und 13 abgewandten Ende des Tisches 2 und lösen diese. Dieser Zustand ist in Figur 5 veranschaulicht. Anschließend fährt der Tisch 2 in seine in Figur 1 gezeigte Grundstellung zurück. Dieser Zustand ist in Figur 6 gezeigt. In diesem werden die beiden Teilstapel 38 und 39 über nicht näher veranschaulichte Mittel einer Weiterverarbeitungsstation zugeführt, so dass kein Stapel mehr auf dem Tisch 2 ruht und der Ausgangszustand gemäß Figur 1 erreicht ist. Nach vertikalem Verfahren des Tisches um das Höhenmaß des jeweiligen als nächstes abzunehmenden Teilstapels, schließen sich die Verfahrensschritte gemäß der Figuren 1 bis 6 erneut an.The grippers 40 and 41 then pull the two partial stacks 38 and 39 to the rollers 12 and 13 facing away from the end of the table 2 and solve them. This condition is in FIG. 5 illustrated. Then the table 2 moves into his in FIG. 1 shown basic position back. This condition is in FIG. 6 shown. In this, the two sub-stacks 38 and 39 are supplied via unspecified means of a further processing station, so that no more stack rests on the table 2 and the initial state according to FIG. 1 is reached. After vertical movement of the table by the height dimension of the respective partial stack to be removed next, the method steps according to the FIGS. 1 to 6 again.

Die in den Figuren 7 bis 12 veranschaulichten Verfahrensabfolgen entsprechen denjenigen der Figuren 1 bis 6, mit dem Unterschied, dass als Ausgangsstapel nicht zwei auf einer Twin-Palette angeordnete Gesamtstapel 31 und 32 vorgesehen sind, sondern ein einziger Gesamtstapel 42, der gleichfalls quaderförmig gestaltet ist, und auf einer nicht gezeigten Palette ruht. Im Gegensatz zum Gesamtstapel 31 bzw. 32, der auf der Twin-Palette ruht und eine Länge der Seite 34 bzw. 35 aufweist, die geringfügig kürzer ist als die Länge der jeweiligen Walze 12 bzw. 13, besitzt der auf der großen Palette befindliche Gesamtstapel 42 eine horizontale Erstreckung im Bereich der Seite 43, die geringfügig kürzer ist als die Gesamtlänge der beiden hintereinander angeordneten Walzen 12 und 13.The in the FIGS. 7 to 12 illustrated process sequences correspond to those of FIGS. 1 to 6 , with the difference that as a starting stack not two arranged on a twin pallet total stack 31 and 32 are provided, but a single total stack 42, which is also cuboid shaped, and rests on a pallet, not shown. In contrast to the total stack 31 and 32, which rests on the twin pallet and has a length of the side 34 and 35, which is slightly shorter than the length of the respective roller 12 and 13, has the total stack located on the large pallet 42 a horizontal extent in the region of the side 43, which is slightly shorter than the total length of the two rollers 12 and 13 arranged one behind the other.

Zum Abnehmen eines Teilstapels von einem derart großen Gesamtstapel 42 wird der Bodenanschlag 33 nicht in der Stellung gemäß der Figuren 1 bis 6 positioniert, sondern, ausgehend aus dieser Position, um einige Winkelgrade schräg gestellt, so dass entweder die Kante 36 des Gesamtstapels 42 zunächst von der Walze 12 in deren der Antriebseinheit 22 zugewandten Bereich, oder die Kante 37 des Gesamtstapels 42 zunächst in dem der Lageraufnahme 23 zugewandten Bereich der Walze 13 kontaktiert wird. In den Figuren 7 bis 12 ist der Bodenanschlag 33 so ausgerichtet, dass als erstes die Walze 13 den Gesamtstapel 42 im Bereich der Ecke 37 kontaktiert.To remove a sub-stack of such a large total stack 42 of the bottom stopper 33 is not in the position according to the FIGS. 1 to 6 positioned, but, starting from this position, inclined by a few degrees, so that either the edge 36 of the entire stack 42 first of the roller 12 in the drive unit 22 facing area, or the edge 37 of the total stack 42 first in the storage receptacle 23rd facing region of the roller 13 is contacted. In the FIGS. 7 to 12 the bottom stop 33 is oriented so that first the roller 13 contacts the total stack 42 in the area of the corner 37.

Ausgehend vom Ausgangszustand gemäß Figur 7 zeigt Figur 8 den Zustand beim Auffächern des Gesamtstapels 42 mittels der zunächst mit diesem in Kontakt gelangenden Walze 13. Figur 9 zeigt den Zustand bei in den Gesamtstapel 42 vollständig eingefahrenen Walzen 12 und 13 und damit vom Gesamtstapel 42 abgetrenntem Teilstapel 44, bei Ergreifen dieses Teilstapels 44 mittels des einen, bei dieser Variante nur benötigten Greifers 41. Figur 10 zeigt den Zustand bei vollständig unter den Teilstapel 44 verfahrenem Tisch 2, Figur 11 den Zustand bei mittels des Greifers 41 bis zum Ende des Tisches 2 gezogenem Teilstapel 44. Figur 12 verdeutlicht das Zurückfahren des Tisches in die Grundstellung gemäß Figur 7. Anschließend wird der Teilstapel 44, der auf dem Tisch 2 ruht, der Weiterverarbeitung zugeführt, somit vom Tisch 2 entfernt, so dass sich der Zyklus gemäß der Figuren 7 bis 12 erneut anschließen kann.Starting from the initial state according to FIG. 7 shows FIG. 8 the state when fanning the entire stack 42 by means of the initially coming into contact with this roller 13th FIG. 9 shows the state when in the total stack 42 completely retracted rollers 12 and 13 and thus separated from the total stack 42 part stack 44, when gripping this sub-stack 44 by means of the one, in this variant, only required gripper 41st FIG. 10 shows the state with completely moved under the partial stack 44 table 2, FIG. 11 the state in by means of the gripper 41 to the end of the table 2 drawn part stack 44th FIG. 12 illustrates the return of the table in the basic position according to FIG. 7 , Subsequently, the partial stack 44, which rests on the table 2, fed to the further processing, thus removed from the table 2, so that the cycle according to the FIGS. 7 to 12 connect again.

Die erfindungsgemäße Vorrichtung ist somit für unterschiedliche Palettengrößen und für einen Gesamtstapel oder für eine aus zwei Gesamtstapeln gebildete Gesamtstapelanordnung verwendbar. Unter diesem Aspekt kommt der Ausrichtung der Palette, auf dem der Gesamtstapel bzw. die Gesamtstapel ruhen, bezüglich des Tisches 2 und damit der beiden Walzen 12 und 13 eine besondere Bedeutung zu. Insbesondere ist der Bodenanschlag 33 so in unterschiedlichen Schwenkpositionen anordbar, dass die am Bodenanschlag ausgerichtete Palette mit deren der jeweiligen Walze zugewandten Seite unter einem Winkel von 2 bis 10°, insbesondere 2 bis 5°, zur Drehachse der Walze positioniert ist. Im Falle des Abnehmens zweier Teilstapel von zwei nebeneinander angeordneten Gesamtstapeln trifft dieser Winkelpositionierungsbereich für beide Walzen 12, 13 zu. Im Fall, dass nur ein Teilstapel vom Gesamtstapel 42 zu entnehmen ist, gilt der genannte Winkelbereich für eine der Walzen, gemäß Ausführungsbeispiel für die Walze 13. Wesentlich ist, dass in letztgenanntem Fall die eine Walze vor der anderen Walze den Gesamtstapel 42 kontaktiert, unter diesem Aspekt ist der optimale Winkel zu wählen.The device according to the invention can thus be used for different pallet sizes and for a total stack or for a total stack arrangement formed from two total stacks. In this aspect, the orientation of the pallet, on which rest the total stack or the total stack, with respect to the table 2 and thus the two rollers 12 and 13 is of particular importance. In particular, the bottom stop 33 can be arranged in different pivotal positions such that the pallet aligned with the bottom stop is positioned with its side facing the respective roller at an angle of 2 to 10 °, in particular 2 to 5 °, to the axis of rotation of the roller. In the case of removing two partial stacks of two juxtaposed total stacks, this angular positioning range applies to both rollers 12, 13. In the event that only a partial stack of the total stack 42 can be seen, said angle range for one of the rollers, according to the embodiment of the roller 13. It is essential that in the latter case, the one roller in front of the other roller contacts the total stack 42, below In this aspect the optimal angle has to be chosen.
