Querschneiden zu Blattlagen in einem definierten Format zugeschnitten und die Blattlagen zu Blattstapeln gesammelt werden, die anschließend verpackt werden.Cutted to sheet layers in a defined format and the sheet layers are collected into sheet stacks, which are then packaged.
Bevorzugt werden Blattlagen im Kleinformat von A3 bis A5 zugeschnitten und anschließend zu Stapeln mit einer Riesgröße zwischen 200 und 500 Blatt gesammelt. Dabei können acht Stapel oder mehr nebeneinander gebildet und anschließend zur Weiterverarbeitung, beispielsweise zum Verpacken, abtransportiert werden.Sheet layers are preferably cut to size from A3 to A5 and then collected into stacks of a size between 200 and 500 sheets. In this case, eight stacks or more can be formed side by side and then transported away for further processing, for example for packaging.
Die Sammel- und Transportvorrichtung weist einen Zuförderer 1 auf, von dem die Blattlagen zu einer Sammelstation 3 gefördert werden, in der aus den Blattlagen Stapel 4 gebildet werden. Der Zuförderer 1 besteht bevorzugt aus einer Reihe von parallel nebeneinander angeordneten Förderbändern 5, die zum Führen der Blattlagen bevorzugt bis in den Bereich der Sammelstation 3 reichen. Im Bereich vor der Stapelstelle liegen die Blattlagen auf einem Fördertisch 2.The collecting and transporting device has a feed conveyor 1, from which the sheet layers are conveyed to a collection station 3, in which stack 4 are formed from the sheet layers. The feed conveyor 1 preferably consists of a series of conveyor belts 5 arranged parallel to one another, which preferably extend into the region of the collecting station 3 for guiding the sheet layers. In the area in front of the stacking point, the sheet layers lie on a conveyor table 2.
Die Sammelstation 3 besteht aus einer Reihe von sich in Produktlaufrichtung erstreckenden Auflageelementen 6, die mit etwas seitlichem Abstand voneinander angeordnet sind und deren die Stapel 4 tragenden Oberflächen fluchtend in einer horizontalen Ebene verlaufen. Auslaufseitig schließt sich an dieThe collecting station 3 consists of a series of support elements 6 extending in the product running direction, which are arranged at a slightly lateral distance from one another and whose surfaces carrying the stacks 4 run in a horizontal plane. The outlet side closes to the
Auflageelemente 6 als Abförderer ein Querförderer 7 an, von dem die fertigenSupport elements 6 as a discharge conveyor to a cross conveyor 7, from which the finished
Blattstapel 4 quer zur Produktlaufrichtung zu einer nicht dargestellten Packstation abtransportiert werden.Sheet stack 4 are transported transversely to the product direction to a packing station, not shown.
Im Bereich der Sammelstation 3 sind weitere Stapelbildungs- und Übergabeelemente angeordnet, die eine kantengenaue Ablage der Blattlagen zu einem Stapel 4 und dessen Übergabe an den Querförderer 7 sicherstellen: Die einlaufseitige Begrenzung des Stapelbereichs wird von einer Reihe von Begrenzungs-Schüttelelementen 8 gebildet, von denen eines in Figur 4 detaillierter dargestellt ist. Es besteht aus zwei mit Abstand voneinander angeordneten waagerechten Tragteilen 8.1 und zwei sich fluchtend anschließenden senkrecht nach unten abgewinkelten Begrenzungsteilen 8.2 an deren senkrechten hinteren Begrenzungskanten die Blattlagen beim Stapeln ausgerichtet werden. Für eine kantengenaue Ablage werden die obersten Blattlagen beim Ablegen auf einen Stapel 4 geschüttelt. Dies erfolgt mittels einer Schüttelplatte 8.3, die senkrecht verlaufend zwischen den Begrenzungskanten angeordnet ist und von einem Schüttelantrieb 8.4 geschüttelt wird. Oben auf den Tragteilen 8.1 ist eine Halteplatte 8.5 befestigt, in der eine sich quer über die Arbeitsbreite erstreckende Führungsleiste 14 gelagert ist. Die Führungsleiste 14 dient dazu, die Begrenzungs- und Schüttelelemente 8 aufzunehmen.In the area of the collecting station 3 further stacking and transfer elements are arranged, which ensure edge-accurate storage of the sheet layers to a stack 4 and its transfer to the cross conveyor 7: The inlet-side boundary of the stacking area is formed by a series of boundary-shaking elements 8, of which one is shown in more detail in FIG. It consists of two spaced-apart horizontal support members 8.1 and two aligned subsequent perpendicular downwardly angled boundary parts 8.2 at the vertical rear boundary edges of the sheet layers are aligned during stacking. For an edge-exact storage, the uppermost sheet layers are shaken when depositing on a stack 4. This is done by means of a shaking plate 8.3, which extends perpendicularly between the boundary edges is arranged and shaken by a shaker 8.4. On top of the supporting parts 8.1, a holding plate 8.5 is fixed, in which a transversely extending over the working width guide rail 14 is mounted. The guide rail 14 serves to receive the limiting and shaking elements 8.
Zwischen den Auflageelementen 6 sind senkrecht sich in Produktlaufrichtung erstreckende Seitenschüttelbleche 9 angeordnet, von denen die Seitenkanten der Stapel 4 bei der Stapelbildung geschüttelt werden. Die Vorderkanten der Blattlagen werden von sich quer über die Arbeitsbreite angeordneten Stopperelementen abgestoppt, die in den Figuren nicht dargestellt sind. Die Auflageelemente 6, die Begrenzungs- und Schüttelelemente 8, zwei Schüttelbleche 9 und die Stopperelemente bilden so beim Ablegen der Blattlagen eine oben offene Sammelbox, in der die Stapel 4 gebildet werden.Between the support elements 6 are arranged vertically extending in the product direction Seitenschüttelbleche 9, of which the side edges of the stack 4 are shaken in the stack formation. The leading edges of the sheet layers are stopped by arranged across the working width stopper elements, which are not shown in the figures. The support elements 6, the boundary and shaking elements 8, two shaking plates 9 and the stopper elements thus form when depositing the sheet layers an open-topped collection box in which the stacks 4 are formed.
Zum Herausschieben der fertigen Stapel 4 aus der Stapelbox in Richtung zum Querförderer 7 dienen Schiebeelemente 10, die in Figur 2 detaillierter dargestellt sind. Jedes Schiebeelement 10 besteht aus zwei senkrechten Schiebeleisten 10.1 , die quer zur Produktlaufrichtung jeweils außen neben den Begrenzungsteilen 8.2 und parallel zu diesen angeordnet sind. An jede Schiebeleiste 10.1 schließt sich eine waagerechten Tragleiste 10.2 an, die sich jeweils neben einem Tragteil 8.1 des Begrenzungselements 8 erstreckt. Die Schiebeleisten 10.1 schieben einen fertigen Stapel 4 in Produktlaufrichtung aus der Sammelbox, so dass in dieser ein neuer Stapel gebildet werden kann. Vorteilhaft werden die Blattlagen auf den Tragleisten 10.2 zwischengelagert, während die fertigen Stapel 4 abtransportiert werden. Beim Zurückfahren der Schiebeelemente gegen Produktlaufrichtung werden die zwischengelagerten Blattlagen an die Auflageelemente 6 übergeben.To push out the finished stack 4 from the stacking box in the direction of the transverse conveyor 7 serve sliding elements 10, which are shown in more detail in Figure 2. Each sliding element 10 consists of two vertical sliding strips 10.1, which are arranged transversely to the product running direction in each case outside the boundary parts 8.2 and parallel to them. To each slide bar 10.1 is followed by a horizontal support bar 10.2, which extends in each case adjacent to a support member 8.1 of the limiting element 8. The sliding strips 10.1 push a finished stack 4 in the product running direction from the collection box, so that in this a new stack can be formed. Advantageously, the sheet layers are stored on the support strips 10.2, while the finished stack 4 are transported away. When moving back the sliding elements against product running direction, the intermediate sheet layers are transferred to the support elements 6.
Zur anschließenden Übergabe der Stapel 4 an den Querförderer 7 dienen Elemente, von denen die Stapel 4 beim Transport festgeklemmt gehalten werden, um ein Verrutschen der gestapelten Blattlagen zu verhindern. Geeignete Elemente sind Wagen mit Klemmfingern, von denen die Stapel 4 so gehalten werden, dass ihre Form erhalten bleibt. Damit die anderen Teile sichtbar sind, sind diese Elemente in den Figuren nicht dargestellt. Die vorstehend beschriebenen Elemente der Sammel- und Transportvorrichtung sind auf folgende Weise in dem Gestell der Vorrichtung gelagert:For the subsequent transfer of the stack 4 to the cross conveyor 7 serve elements of which the stack 4 are kept clamped during transport to prevent slippage of the stacked sheet layers. Suitable elements are carriages with clamping fingers, of which the stacks 4 are held so that their shape is maintained. So that the other parts are visible, these elements are not shown in the figures. The elements of the collecting and transporting device described above are mounted in the frame of the device in the following manner:
Die Stopperelemente der Sammelbox und der Querförderer 7 sind ortsfest gelagert. Der Zuförderer 5, die Begrenzungs- und Schüttelelemente 8, die Seitenschüttelbleche 9 und die Schiebeelemente 10 sind an vertikal bewegbaren Seitenwangen 1 1 gelagert, so dass ihre Position in vertikaler Richtung den wachsenden Stapelhöhen angepasst werden kann. Die Schiebeelemente 10 sind zusätzlich vertikal und zugleich horizontal in und gegen Produktlaufrichtung relativ zu den übrigen an den Seitenwangen 11 gelagerten Elementen mittels eines Antriebs bewegbar, damit sie hochfahren und die Schiebebewegung durchführen können. Um die einlaufseitige Begrenzung der Sammelbox in Abhängigkeit von der Formatlänge der Blattlagen einstellen zu können, sind die Seitenwangen 1 1 mit den daran befestigten Elementen zusätzlich begrenzt horizontal in und gegen Produktlaufrichtung verstellbar gelagert.The stopper elements of the collection box and the cross conveyor 7 are stored stationary. The feed conveyor 5, the limiting and shaking elements 8, the Seitenschüttelbleche 9 and the sliding elements 10 are mounted on vertically movable side walls 1 1, so that their position in the vertical direction can be adapted to the growing stack heights. The sliding elements 10 are additionally vertically and horizontally movable in and against the product running direction relative to the other mounted on the side walls 11 elements by means of a drive so they can start up and perform the sliding movement. In order to adjust the inlet-side boundary of the collection box in dependence on the format length of the sheet layers, the side walls 1 1 are mounted with the attached elements additionally limited horizontally adjustable in and against product travel direction.
Damit unterschiedliche Formatbreiten der Blattlagen und eine unterschiedliche Nutzenanzahl verarbeitet werden können, sind nach der Erfindung die von der Formatbreite und/oder Nutzenanzahl abhängig quer zu positionierenden Elemente besonders vorteilhaft gestaltet und gelagert:In order to be able to process different format widths of the sheet layers and a different number of uses, according to the invention the elements which are to be positioned transversely to be positioned depending on the format width and / or number of use are designed and stored in a particularly advantageous manner:
Die auf die Stapelseiten einwirkenden Seitenschüttelbleche 9 sind gemeinsam mit den Oberbändern 5, von denen die Blattlagen in den Stapelbereich geführt werden, quer verstellbar. Die Seitenschüttelflächen 9 werden zwischen zwei parallel gebildete Blattstapel 4 positioniert. Falls weniger Nutzen als möglich gestapelt werden, werden die überflüssigen Elemente in seitliche Parkpositionen verfahren.The Seitenschüttelbleche 9 acting on the stack sides are transversely adjustable together with the upper belts 5, of which the sheet layers are guided in the stacking area. The side shaking surfaces 9 are positioned between two sheet stacks 4 formed in parallel. If fewer benefits are stacked than possible, the redundant items are moved to lateral parking positions.
Um die Anzahl der Querverstellungen bei einem Formatwechsel erheblich zu verringern, werden jeweils ein Auflageelement 6, ein Begrenzungs- und Schüttelelement 8 und ein Schiebeelement 10 gemeinsam als Einheit quer verschoben. Dazu sind die beiden Schiebeleisten 10.1 eines Schiebeelements 10 jeweils außen neben den beiden Begrenzungsteilen 8.2 eines Begrenzungs- und Schüttelelements 8 angeordnet. Die Schüttelplatte 8.3 ist zwischen den beiden Begrenzungsteilen 8.2 befestigt. Ein Auflageelement 6, das den Boden der Sammelbox bildet, ist unterhalb der Schüttelplatte 8.3 ebenfalls zwischen den Begrenzungsteilen 8.2 angeordnet. Diese Gestaltung ermöglicht es, mittels eines einzigen seitlich an einem Begrenzungsteil 8.2 angreifenden Verstellelements, beispielsweise einer Verstellstange 13, die aus einem Auflageelement 6, einem Schiebeelement 10 und einem Begrenzungs- und Schüttelelement 8 bestehende Einheit gemeinsam quer zur Produktlaufrichtung zu verstellen und auf die neue Formatbreite zu positionieren. Dies vereinfacht die Querpositionierung der Elemente erheblich.In order to reduce the number of transverse adjustments in a format change considerably, each support element 6, a limiting and shaking element 8 and a sliding element 10 are moved together as a unit transverse. For this purpose, the two sliding strips 10.1 of a sliding element 10 are each arranged outside next to the two boundary parts 8.2 of a limiting and shaking element 8. The Schüttelplatte 8.3 is attached between the two boundary parts 8.2. A support element 6, which covers the floor the collecting box forms, is also arranged below the shaking plate 8.3 between the boundary parts 8.2. This design makes it possible, by means of a single side engaging on a boundary part 8.2 adjusting element, for example, an adjusting rod 13, the unit consisting of a support element 6, a sliding element 10 and a limiting and shaking element 8 to adjust together across the product direction and the new format width to position. This considerably simplifies the transverse positioning of the elements.
Die beiden Schiebeleisten 10.1 eines Schiebeelements 10 sind bevorzugt unterhalb des zugehörigen Auflageelements 6 mit einer Querleiste verbunden, damit sie ohne Kollision mit dem Begrenzungs- und Schüttelement 8 nach oben und ohne Kollision mit einem Seitenschüttelblech 9 in und gegen Produktlaufrichtung bewegt werden können.The two sliding strips 10.1 of a sliding element 10 are preferably connected below the associated support element 6 with a transverse bar, so that they can be moved without collision with the boundary and pouring element 8 upwards and without collision with a Seitenschüttelblech 9 in and against the product direction.
Zum Transport der geschuppten Blattlagen und/oder der Stapel 4 sind ein oder mehrere Förderstrecken auf besonders vorteilhafte Weise gestaltet. Die Förderstrecken werden oder teilweise von ebenen Oberflächen von Tragelementen gebildet, die aus einem porösen Keramikwerkstoff mit offenen Poren gefertigt sind. Die Poren weisen einen mittleren Durchmesser von weniger als 100 μm, bevorzugt weniger als 20 μm, auf. Die Tragelemente sind an ihrer Unterseite an eine Druckluftzufuhr angeschlossen, so dass Druckluft zur Bildung eines Luftpolsters aus der fördernden Oberfläche austritt und so die Reibung mit den Blattlagen und/oder Stapeln 4 auf minimale Werte verringert. Diese Bauweise ermöglicht Förderstrecken mit sehr geringer Bauhöhe im Vergleich zu Förderbändern. So lassen sich quer verstellbare Förderelemente innerhalb des Bereichs der maximalen Fallhöhe der Blattlagen beim Stapeln anordnen. Bevorzugt sind bei der Sammel- und Transportvorrichtung die Auflageelemente 6, der Querförderer 7 und der Einlauf in die Sammelstation 3, insbesondere der Führungstisch 2, aus dem plattenförmigen porösen Keramikwerkstoff mit offenen Poren gefertigt. To transport the scaly sheet layers and / or the stack 4, one or more conveyor lines are designed in a particularly advantageous manner. The conveying paths are formed in part or by planar surfaces of supporting elements, which are made of a porous ceramic material with open pores. The pores have an average diameter of less than 100 .mu.m, preferably less than 20 .mu.m. The support members are connected at their underside to a compressed air supply, so that compressed air emerges from the conveying surface to form an air cushion and thus reduces the friction with the sheet layers and / or stacks 4 to minimum values. This design allows conveyor lines with very low height compared to conveyor belts. Thus, transversely adjustable conveying elements can be arranged within the range of the maximum drop height of the sheet layers during stacking. Preferably, in the collecting and transporting device, the support elements 6, the cross conveyor 7 and the inlet to the collecting station 3, in particular the guide table 2, made of the plate-shaped porous ceramic material with open pores.
