Abstract

The invention concerns a device for the intermediate stacking of material that is to be cut, wherein the material is supplied from the work table of one work station, especially a jolting table, to a fork lift, on which the material is made into component stacks with boards positioned between them, and thence to another work station, especially the cutting table of a cutting machine. The object of the invention is to provide a device that makes it possible to stack materials that are to be cut without the component stacks getting displaced. This object is attained in accordance with the invention in that movable stops (13) are positioned below the level of the supporting surfaces (20, 21) of the work tables (10, 12), whereby the stops, when they are in, are outside of the stroke space that occurs when the boards (7a, 7b, 7c, 7d, 7e) are raised and lowered, whereby the stops, when they are out, engage the stroke space, and whereby the supporting surface (19) of the board (7e) delineates a plane in conjunction with the supporting surfaces of the work tables when the stops are out and a board (7e) is laid on them.

Description

Die Erfindung betrifft eine Vorrichtung zum . Zwischenstapeln von Schneidegut, bei der das Schneidegut von dem Arbeitstisch einer ersten Arbeitsstation, insbesonderen einem Rütteltisch, einem Stapellift zugeführt wird, auf dem das Schneidegut unter Zwischenlagerung von Brettern zu Teilstapeln gelagert wird und von dort dem Arbeitstisch einer zweiten Arbeitsstation, insbesondere einem Schneidetisch einer Schneidemaschine, zugeführt wird.The invention relates to a device for. Intermediate stacking of material to be cut, in which the material to be cut is fed from the work table to a first work station, in particular a vibrating table, to a stack lift, on which the material to be cut is stored in part stacks with the intermediate storage of boards and from there to the work table of a second work station, in particular a cutting table of a cutting machine , is fed.

Eine derartige Vorrichtung ist aus der DE-PS-1 244 711 bekannt. Bei dieser wird das Schneidegut vor dem Schneidevorgang auf einem Rütteltisch gerüttelt, um dadurch die einzelnen Blätter genau zueinander auszurichten. Im Anschluß an den Rüttelvorgang erfolgt eine Zwischenstapelung des Schneideguts auf einem Stapellift. Die Teilstapel liegen dabei auf dem Stapellift übereinander, wobei zwischen den einzelnen Teilstapeln Bretter angeordnet sind. Das Verschieben der Teilstapel vom Rütteltisch auf die Bretter bzw. von den Brettern auf den Schneidetisch erfolgt in einfacher Art und Weise dadurch, daß die Bretter als Luftbretter ausgebildet sind, d. h. sie sind mit einer Luftzufuhr sowie auf der den aufliegenden Teilstapeln zugewandten Oberfläche mit Luftaustrittsdüsen versehen.Such a device is known from DE-PS-1 244 711. In this case, the material to be cut is shaken on a vibrating table before the cutting process, in order to thereby align the individual sheets precisely with one another. After the shaking process, the material to be cut is stacked on a stack lift. The partial stacks lie one above the other on the stack lift, boards being arranged between the individual partial stacks. Moving the partial stack from the vibrating table to the boards or from the boards to the cutting table is done in a simple manner in that the boards are designed as air boards, d. H. they are provided with an air supply and on the surface facing the partial stacks with air outlet nozzles.

Eine derartige Vorrichtung weist jedoch den Nachteil auf, daß es durch ungleichmäßig hohes Auftragen der einen Teilstapel bildenden Einzelbogen dazu kommen kann, daß das auf dem Teilstapel aufliegende Luftbrett schief liegt. Eine Bündigkeit des Luftbrettes mit den Auflageflächen der Arbeitstische ist damit nicht mehr gewährleistet. Beim Beschicken oder Entladen des auf dem obersten Luftbrett liegenden Teilstapels wird der unter diesem Brett liegende Teilstapel verschoben. Beim Schneiden dieses Teilstapels können sich dann keine exakten Schnittgrößen mehr ergeben.However, such a device has the disadvantage that the unevenly high application of the individual sheets forming a partial stack can result in the air board resting on the partial stack being crooked. This means that the air board is no longer flush with the support surfaces of the work tables. When loading or unloading the partial stack lying on the top air board, the partial stack below this board is moved. When cutting this partial stack, exact cutting sizes can no longer result.

Aufgabe der Erfindung ist es, eine Vorrichtung zu schaffen, mit der es möglich ist, Schneidegut zu stapeln, ohne daß beim Beschicken oder Entladen die Teilstapel in sich verschoben werden.The object of the invention is to provide a device with which it is possible to stack material to be cut without the partial stacks being shifted during loading or unloading.

Gelöst wird die Aufgabe dadurch, daß unterhalb des Niveaus der Auflageflächen der Arbeitstische bewegliche Anschläge angeordnet sind, wobei die Anschläge sich in eingefahrener Position außerhalb des beim Heben und Senken der Bretter gebildeten Hubraumes befinden, in ausgefahrener Position in den Hubraum eingreifen und beim Auflegen eines Brettes auf die ausgefahrenen Anschläge die Auflagefläche des Brettes mit den Auflageflächen der Arbeitstische eine Ebene bildet.The object is achieved in that movable stops are arranged below the level of the support surfaces of the work tables, the stops being in the retracted position outside the displacement formed when the boards are raised and lowered, engaging in the extended position in the extended position and when a board is placed on the board the support surface of the board forms a level with the support surfaces of the work tables on the extended stops.

Beim Beschicken des Stapelliftes wird dieser soweit abgesenkt, daß eine auf diesem liegende Transportpalette und/oder bereits abgelegte Teilstapel unterhalb der Anschläge sich befinden. Sodann werden die Anschläge in die ausgefahrene Position bewegt und das Brett auf diese gelegt. Die Anschläge halten das Brett in dieser Position, in der die Auflagefläche des Brettes mit der Auflagefläche der Arbeitstische eine Ebene bildet. Der abzulegende Teilstapel wird auf das Brett geschoben und anschließend der Stapellift soweit angehoben, daß das oberste Brett mit dem jetzt abgelegten Teilstapel die Anschläge entlastet. Die Anschläge werden in ihre eingefahrene Position bewegt, d. h. sie befinden sich außerhalb des beim Heben und Senken der Bretter gebildeten Hubraumes, der Stapellift wird soweit abgesenkt, daß die Oberfläche des zuletzt abgelegten Teilstapels unterhalb der Anschläge liegt und einen Zwischenraum zur Unterseite des später aufzulegenden Brettes bildet. Schließlich werden die Anschläge zur Aufnahme des nächsten Brettes sowie eines weiteren Teilstapels in die ausgefahrene Position bewegt.When loading the stack lift, it is lowered to such an extent that a transport pallet lying thereon and / or partial stacks already deposited are located below the stops. Then the stops are moved to the extended position and the board is placed on them. The stops hold the board in this position, in which the support surface of the board forms a plane with the support surface of the work tables. The partial stack to be put down is pushed onto the board and then the stack lift is raised so that the top board with the now placed partial stack relieves the stops. The stops are moved to their retracted position, i.e. H. they are located outside of the displacement formed when lifting and lowering the boards, the stack lift is lowered to such an extent that the surface of the last stacked part lies below the stops and forms an intermediate space to the underside of the board to be placed later. Finally, the stops for receiving the next board and a further partial stack are moved into the extended position.

Beim Abarbeiten der Teilstapel wird der Stapellift soweit hochgefahren, daß sich die Anschläge unter das den obersten Teilstapel tragende Brett bewegen lassen. Der Stapellift wird soweit abgesenkt, daß das oberste Brett auf den Anschlägen aufliegt und sich ein Zwischenraum zwischen der Unterseite des obersten Brettes und der Oberfläche des darunter bereitgehaltenen Teifstapels bzw. im Endstadium des Arbeitsablaufs sich ein Zwischenraum zwischen der Unterseite des obersten Luftbretts und der Oberfläche der Transportpalette bildet. Der bereitgelegte Teilstapel wird sodann der zweiten Arbeitsstation zugeführt, das Brett herausgenommen und die Anschläge in die eingefahrene Position bewegt. Es erfolgt dann das Hochfahren des nächsten Teilstapels durch den Stapellift.When processing the partial stack, the stack lift is raised so far that the stops can be moved under the board carrying the uppermost partial stack. The stack lift is lowered to such an extent that the top board rests on the stops and there is a gap between the underside of the top board and the surface of the stack of taps below it, or in the final stage of the workflow there is a gap between the underside of the top air board and the surface of the Transport pallet forms. The prepared partial stack is then fed to the second work station, the board is removed and the stops are moved into the retracted position. The next partial stack is then raised by the stack lift.

Die erfindungsgemäßen Anschläge haben somit in ihrer ausgefahrenen Position die Aufgabe, die horizontale Lage des auf ihnen liegenden Brettes sowie die Bündigkeit der Auflagefläche des Brettes mit den Auflageflächen der Arbeitstische zu gewährleisten. Während üblicherweise der Stapellift die Tragefunktion für die Teilstapel sowie die dazwischen befindlichen Bretter übernimmt, wird diese Tragefunktion für das oberste Brett sowie den darauf befindlichen Teilstapel durch die Anschläge wahrgenom Durch das Trennen des obersten Brettes vom Reststapel während des Beschickens oder Entladens wird verhindert, daß sich der unter dem obersten Brett liegende Teilstapel verschiebt.In their extended position, the stops according to the invention thus have the task of ensuring the horizontal position of the board lying on them and the flushness of the contact surface of the board with the contact surfaces of the work tables. While the stack lift usually takes over the carrying function for the partial stack and the boards in between, this carrying function for the top board and the partial stack located on it is performed by the stops. By separating the top board from the remaining stack during loading or unloading, it is prevented that the partial stack under the top board moves.

Die Befestigung der Anschläge kann sowohl an den Arbeitsstationen als auch am Stapellift erfolgen. Zweckmäßig sind die Anschläge als Klappen ausgebildet, deren eines Ende an der Unterseite der Arbeitstische der Arbeitsstationen schwenkbar befestigt ist und desse freies Ende der Auflage des Brettes dient. Für den Fall der Anordnung der Klappen an der Unterseite der Arbeitstische ergibt sich eine besonders raumsparende Gestaltung des Stapellifts. Zum Verschwenken der Klappe sollten ferner an der Unterseite der Arbeitstische Kraftelemente, insbesondere hydraulische Kraftzylinder, angeordnet sein.The stops can be attached to both the workstations and the stack lift. The stops are expediently designed as flaps, one end of which is pivotally attached to the underside of the work tables of the work stations and the free end of which serves to support the board. If the flaps are arranged on the underside of the work tables, the stack lift is particularly space-saving. To pivot the flap, force elements should also be on the underside of the workbenches, in particular whose hydraulic power cylinder can be arranged.

Um eine stabile Lage des Brettes bezüglich der Auflageflächen der Tische zu gewährleisten, sollten über die Breite des Brettes, d. h. senkrecht zur Verschieberichtung der Teilstapel auf dem Brett, mehrere Klappen mit Kraftelementen vorgesehen sein.In order to ensure a stable position of the board with respect to the contact surfaces of the tables, the width of the board, i. H. perpendicular to the direction of displacement of the partial stack on the board, several flaps with force elements can be provided.

Es bietet sich jedoch gleichfalls an, die Anschläge nicht verschwenkbar, sondern verschiebbar an der Unterseite der Arbeitstische anzuordnen. In einem solchen Fall könnten dornenartig gestaltete Fortsätze in ausgefahrener Position das Brett untergreifen bzw. in entsprechende Ausnehmungen im Brett eingreifen und derart das Brett in bündiger Position zu den Arbeitstischen halten. Die Verschiebung der Fortsätze von der eingefahrenen in die ausgefahrene Position und zurück würde gleichfalls durch Kraftelemente bewirkt.However, it is also advisable to arrange the stops not on the underside of the work tables, but rather on a swivel. In such a case, thorn-like projections could extend under the board in the extended position or engage in corresponding recesses in the board and thus hold the board in a flush position with the work tables. The displacement of the extensions from the retracted to the extended position and back would also be effected by force elements.

Es ist schließlich möglich, die Anschläge nicht an den Arbeitsstationen, sondern am Stapellift verschwenkbar oder verschiebbar anzuordnen.Finally, it is possible not to arrange the stops so that they can be pivoted or displaced at the work stations, but rather at the stack lift.

Vorteilhaft weisen die Bretter an ihrer Unterseite Stützen auf, wobei die Länge der einzelnen Stützen gleich, jedoch größer als die Höhe des unter dem Brett liegenden Teilstapels ist. Der Einsatz derartiger Bretter mit Stützen ist dann angezeigt, wenn die einzelnen Teilstapel aus leichtgewichtigen, qualitativ hochwertigen Einzelbogen bestehen. In diesem Fall ruht nicht die Last aller Teilstapel auf dem unteren Teilstapeln, sondern es stützen sich die Bretter auf den anderen Brettern ab.The boards advantageously have supports on their underside, the length of the individual supports being the same but greater than the height of the partial stack lying under the board. The use of such boards with supports is indicated when the individual partial stacks consist of lightweight, high-quality single sheets. In this case, the load of all partial stacks does not rest on the lower partial stack, but the boards are supported on the other boards.

Um ein leichtes Überschieben der Teilstapel zu gewährleisten, sollten die Bretter als Luftbretter mit Luftein- und -ausblasöffnungen ausgebildet sein.In order to ensure that the partial stacks are easily pushed over, the boards should be designed as air boards with air inlet and outlet openings.

Vorteilhaft weist der Stapellift Räder zum Verfahren auf. Noch während bei ausgefahrenen Anschlägen der auf dem Brett liegende Teilstapel zur nächsten Arbeitsstation verfahren wird, oder während Teilstapel von einer Arbeitsstation über das Brett zur anderen Arbeitsstation befördert werden, kann der Stapellift den Arbeitsbereich verlassen und neues Material heranschaffen.The stacking lift advantageously has wheels for moving. While the partial stack lying on the board is being moved to the next work station when the stops are extended, or while partial stacks are being transported from one work station over the board to the other work station, the stack lift can leave the work area and bring in new material.

Weitere Merkmale der Erfindung sind in der Zeichnung der Figur dargestellt.Further features of the invention are shown in the drawing of the figure.

Diese zeigt einen Längsschnitt durch die Vorrichtung. Zwischen einem teilweise nur dargestellten Rütteltisch 1 sowie einem gleichfalls nur teilweise dargestellten Schneidetisch2 einer Papierschneidemaschine befindet sich ein Stapellift 3. Dieser weist an seiner Unterseite Räder 4 zum Verfahren auf. Die teilweise angehobene Hubgabel 5 des Stapellifts 4 durchgreift eine Palette 6, auf der das Schneidegut unter Zwischenlage von Luftbrettern 7a bis 7e zu Teilstapein 8a bis 8d gelagert wird.This shows a longitudinal section through the device. A stacking lift 3 is located between a shaking table 1, which is only partially shown, and a cutting table 2, which is also only partially shown, of a paper cutting machine. The partially raised lifting fork 5 of the stack lift 4 passes through a pallet 6 on which the material to be cut is stored with the interposition of air boards 7a to 7e to partial stacks 8a to 8d.

An der Unterseite 9 der Arbeitsplatte 10 des Rütteltisches 1 sowie der Unterseite 11 der Arbeitsplatte 12 des Schneidetisches 2 sind senkrecht zur Zeichenebene mehrere Klappen 13 um die Gelenke 14 schwenkbar angeordnet. Dazu greifen gleichfalls an den Unterseiten 9 und 11 angeordnete hydraulische Kraftzylinder 15 mit ihren Kolbenstangen 16 an an den Klappen 13 angeordneten Winkelstücken 17 an.On the underside 9 of the worktop 10 of the vibrating table 1 and on the underside 11 of the worktop 12 of the cutting table 2, a plurality of flaps 13 are arranged pivotably about the joints 14 perpendicular to the plane of the drawing. For this purpose, hydraulic power cylinders 15 also arranged on the undersides 9 and 11 engage with their piston rods 16 on angle pieces 17 arranged on the flaps 13.

Die Anordnung der Klappen an den Unterseiten 9 und 11 sowie die Abmessung der Klappen mit den am freien Klappenende angeordneten Auflagen 18 ist derart, daß in ausgeschwenktem Zustand der Klappen 13, wie in der Figur dargestellt, das Luftbrett 7e auf die Auflagen 18 gelegt werden kann, wobei die Auflagefläche 19 eine Ebene mit den Auflageflächen 20 und 21 der Arbeitsplatten 10 und 12 bildet. In der in der Figur dargestellten Position steht die nicht näher dargestellte Lufteintrittsöffnung des Luftbrettes 7e in Verbindung mit einer schematisch dargestellten Luftglocke 22. Durch diese wird ein Luftstrom in das Brett 7e und dann durch an der Oberseite des Brettes angeordnete Luftaustrittsöffnungen hindurchgeblasen. Der sich oberhalb des Luftbrettes 7e bildende Luftfilm erleichtert das Überschieben des Teilstapels 8e von der Auflagefläche 20 zum Luftbrett 7e.The arrangement of the flaps on the undersides 9 and 11 and the dimension of the flaps with the supports 18 arranged at the free end of the flap is such that, when the flaps 13 are pivoted out, as shown in the figure, the air board 7e can be placed on the supports 18 , wherein the support surface 19 forms a plane with the support surfaces 20 and 21 of the worktops 10 and 12. In the position shown in the figure, the air inlet opening of the air board 7e, which is not shown in any more detail, is connected to an air bell 22, which is shown schematically. An air flow is blown through this into the board 7e and then through air outlet openings arranged on the top of the board. The air film forming above the air board 7e makes it easier to push the partial stack 8e over from the support surface 20 to the air board 7e.

Bei ausgefahrenen Klappen 13 ist die Hubgabel 5 des Stapelliftes 3 soweit nach unten verfahren, daß zwischen der Unterseite des Luftbrettes 7e und der Oberfläche des Teilstapels 8d ein Zwischenraum verbleibt. Durch diesen ist gewährleistet, daß während des Verschiebens des Teilstapels 8e auf das Luftbrett 7e die oberen einzelnen Bogen des Teilstapels 8d nicht mit verschoben werden können.When the flaps 13 are extended, the lifting fork 5 of the stack lift 3 is moved so far down that a gap remains between the underside of the air board 7e and the surface of the partial stack 8d. This ensures that the upper individual sheets of the partial stack 8d cannot be moved during the displacement of the partial stack 8e onto the air board 7e.

Nachdem der Teilstapel 8e sich auf dem Luftbrett 7e befindet, wird die Hubgabel 5 des Stapelliftes 3 geringfügig angehoben, um die Klappen 13 zu entlasten. Im Gegensatz zu den Luftbrettern 7a bis 7d kommt dabei das Luftbrett 7e mit seinen vier Stützen 23 auf dem Luftbrett 7d zum Stehen, wobei es den auf dem Luftbrett 7d befindlichen Teilstapel 8d nicht berührt. Im Unterschied dazu weisen die übrigen Luftbretter 7a bis 7d derartige Stützen 23 nicht auf, das Brett 7b liegt direkt auf dem Teilstapel 8a, das Brett 7c direkt auf dem Teilstapel 8b und das Brett 7d direkt auf dem Teilstapel 8c auf. Es ist jedoch gleichfalls möglich, alle Bretter mit oder ohne Stützen zu versehen.After the partial stack 8e is on the air board 7e, the lifting fork 5 of the stack lift 3 is raised slightly in order to relieve the flaps 13. In contrast to the air boards 7a to 7d, the air board 7e comes to a standstill with its four supports 23 on the air board 7d, whereby it does not touch the partial stack 8d located on the air board 7d. In contrast to this, the other air boards 7a to 7d do not have such supports 23, the board 7b lies directly on the partial stack 8a, the board 7c directly on the partial stack 8b and the board 7d directly on the partial stack 8c. However, it is also possible to provide all boards with or without supports.

Nachdem die Klappen 13 entlastet sind, werden sie über die hydraulischen Kraftglieder 15 zurückgeschwenkt, so daß sie sich außerhalb des beim Heben und Senken der Bretter 7a bis 7e gebildeten Hubraumes befinden (Außenkontur des Hubraumes strichliert dargestellt).After the flaps 13 are relieved, they are pivoted back via the hydraulic force members 15, so that they are located outside of the displacement formed when the boards 7a to 7e are raised and lowered (outer contour of the displacement shown in dashed lines).

Das Einfügen weiterer Teilstapel in den Stapellift bzw. das Abarbeiten der Teilstapel aus dem Stapellift wurde bereits vorstehend erläutert.The insertion of further partial stacks into the stack lift or the processing of the partial stacks from the stack lift has already been explained above.
