The Schlebeleisten 10.1 push a finished stack 4 in the product direction of the collection box, so that in this a new stack can be formed. Advantageously, the sheet layers are placed on the support strips 10.2 between, 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 dargestelit.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.

Die vorstehend beschriebenen Elemente der Sammel- und Transportvorrichtung sind auf folgende Welse In dem Gestell der Vorrichtung gelagert:
Die Stopperelemente der Sammelbox und der Querförderer 7 sind ortsfest gelagert. Der Zuförderer 5, die Begrenzungs- und Schüttetelemente 8, die Seltenschüttelbleche 9 und die Schlebeelemente 10 sind an vertikal bewegbaren Seltenwangen 11 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 Seltenwangen 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 11 mit den daran befestigten Elementen zusätzlich begrenzt horizontal in und gegen Produktlaufrichtung verstellbar gelagert.The above-described elements of the collection and transport device are stored on the following catfish in the frame of the device:
The stopper elements of the collection box and the cross conveyor 7 are stored stationary. The feed conveyor 5, the limiting and pouring elements 8, the Seltenschüttelbleche 9 and the trailing elements 10 are mounted on vertically movable rare cheeks 11, 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 elements mounted on the Seltenwangen 11 elements by means of a drive, so that 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 cheeks 11 are mounted with the elements attached thereto additionally limited horizontally adjustable in and against product travel direction.

Damit unterschiedliche Formatbreiten der Blattlagen und eine unterschiedliche Nutzenanzahl verarbeitet werden können, sind die von der Formatbreite und/oder Nutzenanzahl abhängig quer zu positionierenden Elemente besonders vorteilhaft gestaltet und gelagert:
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 Seltenschüttelflächen 9 werden zwischen zwei parallel gebildete Blattstapel 4 positioniert. Falls weniger Nutzen als möglich gestapelt werden, werden die überflüssigen Elemente in seitliche Parkpositionen verfahren.Thus, different format widths of the sheet layers and a different number of benefits can be processed, the dependent on the format width and / or number of benefits transversely positioned elements are designed and stored particularly advantageous:
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 rare-earth 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 Schlebeelements 10 jeweils außen neben den beiden Begrenzungsteilen 8.2 eines Begrenzungs- und Schütteielements 8 angeordnet. Die Schütteiplatte 8.3 ist zwischen den belden Begrenzungsteilen 8.2 befestigt. Ein Auflageelement 8, 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.To significantly reduce the number of transverse adjustments in a format change, each support element 6, a limiting and shaking element 8 and a sliding element 10 are moved together as a unit across. For this purpose, the two sliding strips 10.1 of a traction element 10 are each arranged outside next to the two boundary parts 8.2 of a delimiting and Schütteielements 8. The Schütteiplatte 8.3 is attached between the Belden boundary parts 8.2. A support element 8, 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 laterally acting 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 Schlebeleisten 10.1 eines Schiebeelements 10 sind bevorzugt unterhalb des zugehörigen Auflageelemente 8 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 Schlebeleisten 10.1 a sliding element 10 are preferably connected below the associated support elements 8 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 Welse gestaltet. Die Förderstrecken werden 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 for particularly advantageous catfish. The conveying paths are formed by flat surfaces of supporting elements, which are made of a porous ceramic material with open pores. The pores have a mean diameter of less than 100 microns, preferably less than 20 microns, on. The support elements are connected to a compressed air supply at the bottom, so that compressed air escapes from the conveying surface to form an air cushion, thus reducing friction with the sheet layers and / or stacks 4 to minimal 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 collection station 3, in particular the guide table 2, made of the plate-shaped porous ceramic material with open pores.
