Description

Die Erfindung betrifft einen Ausleger für eine Bogen verarbeitende Druckmaschine mit einer Vorrichtung zum Wechseln des Auslegerstapels nach dem Oberbegriff von Anspruch 1.The invention relates to a boom for a sheet processing Printing machine with a device for changing the Boom stack according to the preamble of claim 1.

[Stand der Technik][State of the art]

Ein Ausleger dieser Art ist aus DE 195 16 071 A1 mit einer Vorrichtung zum Stapelwechsel an einer Bogendruckmaschine bei kontinuierlicher Bogenzuführung bekannt. Dabei kommt ein Trennelement, gebildet aus einer außerhalb des Stapelbereiches angeordneten Welle und einem bzw. mehreren Keilen zur Anwendung, welches den für den Stapelrecheneinschub erforderlichen Zwickel bildet. Das Trennelement liegt dabei im Bereich der Vorderkante auf dem oberen Bogen des Hauptstapels auf. Gleichzeitig legen sich oberhalb des Trennelementes die weiterhin zugeführten Zwischenstapelbogen auf dem nun entstehenden Hilfsstapel auf. Die oberhalb des Trennelementes angesammelten Bogen werden freigegeben, indem das Trennelement um die Welle drehend dem abgesenkten Hauptstapel folgt und aus dem Stapelbereich wieder herausschwenkt. Diese Lösung ist auf die Anwendung von Stapelrechen begrenzt, da die Keile in die Zwischenräume des Stapelrechens auf die Oberkante des Hauptstapels eingreifen müssen. A boom of this type is known from DE 195 16 071 A1 Device for changing stacks on a sheet-fed press continuous sheet feeding known. This comes in Separating element, formed from an outside of the stacking area arranged shaft and one or more wedges for Application that the necessary for the stacking rack Gusset forms. The separating element lies in the area the leading edge on the top sheet of the main stack on. At the same time lie above the separating element intermediate stack sheet still fed on the now emerging Aid pile on. The above the separating element accumulated sheets are released by the separator rotating around the shaft follows the lowered main stack and swings out of the stack area again. This solution is limited to the use of stacking rakes because of the wedges in the spaces between the stacking rake on the top edge of the Main stack must intervene.

Weiterhin ist aus DE 198 19 491 C1 ein Ausleger mit einer Vorrichtung zum Stapelwechsel an einer Bogendruckmaschine bei kontinuierlicher Bogenzuführung bekannt, die vor einem Auslegerstapel (erstes Stapelsystem) als Weiche wirkend angeordnet ist und die Bogen wahlweise auf dem Auslegerstapel (erstes Stapelsystem) oder auf ein dem ersten Stapelsystem vorgeordnetes zweites Stapelsystem ablegt. Soll beispielsweise ein Non-Stop-Stapelwechsel erfolgen, wird die Weiche derart aktiviert, dass die Bogen auf das zweite Stapelsystems ablegbar sind. In der Zwischenzeit kann beispielsweise der Hauptstapel des ersten Stapelsystems abgesenkt und aus dem Ausleger abgefahren werden. Vorher wird ein neues Stapelbrett bzw. ein Stapelrechen eingelegt und anschließend die bisher dem zweiten Stapelsystem zugeführten Bogen erneut dem Auslegerstapel (erstes Stapelsystem) zugeführt. In der Zwischenzeit kann der Stapel des zweiten Stapelsystemes gewechselt werden.Furthermore, from DE 198 19 491 C1 a boom with a Device for changing stacks on a sheet-fed press Continuous sheet feeding known in front of a delivery pile (first stacking system) arranged to act as a switch and the sheets are optionally on the delivery stack (first Stacking system) or on an upstream of the first stacking system second stack system. For example, a Non-stop stack changes take place, the turnout is like this activated that the sheets can be deposited on the second stacking system are. In the meantime, for example, the main stack of the first stacking system lowered and out of the boom be driven off. Before that, a new stacking board or inserted a stacking rake and then the previous one second sheet system fed sheets again to the delivery stack (first stacking system) fed. In the meantime the stack of the second stack system can be changed.

Beim Wechsel eines Stapels ist von Nachteil, dass das konturengerecht gestapelte Bogenmaterial beim Stapelwechsel seine Lage auf dem Stapel verändern kann. Durch die Absenkbewegung und/oder durch die insbesondere im oberen Stapelbereich zwischen Bogen eingeschlossene Luft (Reduzierung der Haftreibung) ist die Lage der Bogen auf dem Stapel veränderbar.The disadvantage of changing a stack is that it conforms to the contours stacked sheet material when changing stacks can change its position on the stack. By the lowering movement and / or particularly in the upper stack area Air trapped between arches (reduction of Static friction) the position of the sheets on the stack can be changed.

[Aufgabe der Erfindung]OBJECT OF THE INVENTION

Der Erfindung liegt die Aufgabe zugrunde, einen Ausleger der eingangs beschriebenen Art zu schaffen, der die genannten Nachteile vermeidet, der insbesondere eine Lageveränderung des Bogenmaterials beim Stapelwechsel spürbar reduziert und eine verbesserte Ausbildung einer kantengerechten Stapelbildung gestattet. The invention has for its object a boom of to create the type described above, the said Avoids disadvantages, in particular a change in position of sheet material when changing stacks is noticeably reduced and an improved formation of an edge-aligned stack formation allowed.

Erfindungsgemäß wird die Aufgabe durch die Ausbildungsmerkmale von Anspruch 1 gelöst. Weiterbildungen ergeben sich aus den abhängigen Ansprüchen.According to the invention, the task is based on the training features solved by claim 1. Further training results from the dependent claims.

Ein erster Vorteil der Erfindung ist darin begründet, dass der Ausleger an einer vertikal bewegbaren Stapeltragplatte und einer gestellseitig, bevorzugt lösbar befestigten Traverse, wenigstens eine einer Kante, beispielsweise der Vorderkante, des gestapelten Bogenmaterials benachbart zugeordnete, längenveränderbare Kantenführungseinrichtung aufweist. Diese Kantenführungseinrichtung führt bei Bedarf das Bogenmaterial beim Ablegen in seiner vorbestimmten Stapellage und führt insbesondere das Bogenmaterial beim Absenken des Hauptstapels. Damit wird die Lageveränderung des Bedruckstoffes, beispielsweise das Schieben von Bogenmaterial, vermieden und die bereits während der Auslage hergestellte kantengerechte Stapelbildung bleibt beim Absenken (des Stapels) des Bogenmaterials unverändert.A first advantage of the invention is based on the fact that the boom on a vertically movable stacking support plate and a frame-side, preferably releasably attached cross-member, at least one edge, for example the leading edge, adjacent to the stacked sheet material, has variable-length edge guide device. This Edge guide device guides the sheet material if necessary when placed in its predetermined stacking position and leads especially the sheet material when lowering the main stack. This changes the position of the substrate, for example, the pushing of sheet material, avoided and the right-edged one that was already produced during delivery Stacking remains when the sheet material is lowered unchanged.

Ein weiterer Vorteil besteht darin, dass die Kantenführungseinrichtung bei der vertikalen Aufwärts- bzw. Absenkbewegung des Stapels längenveränderbar ist. Damit ist beim Wechsel eines Stapels, insbesondere bei der Absenkbewegung, unabhängig von der Größe des Stapels eine ständige Führung im Bereich einer Kante, beispielsweise der Vorderkante, des gestapelten Bogenmaterials gewährleistet.Another advantage is that the edge guide in the vertical upward or downward movement the length of the stack is variable. So that's when changing of a stack, especially when lowering, independently of the size of the stack a constant guide in the area one edge, for example the leading edge, of the stacked one Guaranteed sheet material.

Vorteilhaft ist ferner, dass die Kantenführungseinrichtung in einem geringen Abstand zur Kante des den Stapel bildenden Bogenmaterials angeordnet ist. Damit ist eine Reibung zwischen einer Kante des Bogenmaterials und der Kantenführungseinrichtung beim Absenken des Stapels (Relativbewegung) vermeidbar, welche die gewünschte Lage des Bogenmaterials auf dem Stapel negativ beeinflussen könnte. It is also advantageous that the edge guide device in a short distance from the edge of the one forming the stack Sheet material is arranged. So there is a friction between an edge of the sheet material and the edge guide when lowering the stack (relative movement) avoidable on the desired location of the sheet material could adversely affect the stack.

Ebenso von Vorteil ist, dass die Kantenführungseinrichtung bevorzugt an einer Traverse eingeordnet ist und dass diese Traverse lösbar mit dem Auslegergestell verbunden ist. Bevorzugt ist die Kantenführungseinrichtung lösbar mit der Traverse verbunden. Somit ist der Stapelbetrieb auch ohne Kantenführungseinrichtung realisierbar und beim Stapelwechsel wird kein benötigter Freiraum versperrt.Another advantage is that the edge guide device is preferably arranged on a traverse and that this Traverse is detachably connected to the boom frame. Prefers the edge guide device is detachable with the traverse connected. Thus, the batch operation is also without edge guiding device feasible and when changing stacks no required free space blocked.

In einer weiteren Ausbildung ist von Vorteil, dass die lösbare Traverse, vorzugsweise manuell, vom Auslegergestell trennbar ist und mit der Kantenführungseinrichtung, beispielsweise an der Stapeltragplatte, lösbar fixierbar ist (Parkposition) .In a further training it is advantageous that the detachable Traverse, preferably manual, separable from the boom frame and with the edge guide device, for example on the stack support plate, can be detachably fixed (parking position).

Die erfindungsgemäße Ausbildung des Auslegers ist universell, beispielsweise für den Non-Stop-Stapelwechsel oder für den Päckchenbetrieb (untereinander getrennte Teilstapel in bestimmter Stückzahl von Bogenmaterial), einsetzbar.The design of the boom according to the invention is universal, for example for the non-stop stack change or for the Parcel operation (separate sub-stacks in certain Number of sheets), can be used.

Die erfindungsgemäße Ausbildung ist nicht auf den Einsatz einer einzelnen Kantenführungseinrichtung beschränkt. Vielmehr sind auch mehrere Kantenführungseinrichtungen an der bzw. den relevanten Kanten des Stapels anordbar.The training according to the invention is not on use a single edge guide device limited. Much more are also several edge guide devices on the or the relevant edges of the stack can be arranged.

Ein Ausleger 1 für den Non-Stop-Stapelwechsel besteht im Wesentlichen aus einem umlaufenden Fördersystem 4 mit daran angeordneten Greifersystemen 3, die in Förderrichtung 9 das von einem vorgeordneten Druckwerk oder einer Veredlungseinheit kommende Bogenmaterial 2 einem Auslegerstapel 5 zuführen. Dabei wird das Bogenmaterial 2 an feststehenden Bogenleiteinrichtungen 8 und format- und druckbildabhängig verstellbaren Bogenleiteinrichtungen 10 entlang geführt. Die Bogenleiteinrichtungen 8,10 sind bevorzugt wahlweise mit Blasluft- oder Saugluft umschaltbar steuerbar. Oberhalb des Auslegerstapels 5 ist in einem Feld ein Pneumatiksystem 6 angeordnet, dass das Ablegen der ankommenden Bogenmaterialien 2 auf den Auslegerstapel 5 unterstützt.A boom 1 for the non-stop stack change consists in Essentially from a circulating conveyor system 4 with it arranged gripper systems 3, the 9 in the conveying direction from an upstream printing unit or a finishing unit feed coming sheet material 2 to a delivery stack 5. The sheet material 2 is attached to fixed sheet guiding devices 8 and adjustable depending on format and print image Sheet guiding devices 10 guided along. The Sheet guiding devices 8, 10 are preferably optionally available with Blown air or suction air switchable controllable. Above the Boom stack 5 is a pneumatic system 6 in a field arranged that the depositing of the incoming sheet materials 2 supported on the boom stack 5.

Das in Förderrichtung 9 ankommende Bogenmaterial 2 wird in bekannter Weise von einer Bogenbremseinrichtung 7 abgebremst und auf den Auslegerstapel 5 gegen Vorderkantenanschläge 11 abgelegt. Parallel zu den Seitengestellen des Auslegers 1 sind einschwenkbare Führungen, zum Beispiel Winkelschienen, zur Aufnahme einer Hilfsstapelunterlage 12, zum Beispiel eines Brettes oder eines Rechens, angeordnet. Die Hilfsstapelunterlage 12 ist in Einschubrichtung 13 horizontal zuführbar bzw. entgegen der Einschubrichtung 13 entfernbar. Zum Zwecke der Entnahme von Probebogen oder zur Bildung des Hilfsstapels im Auslegerstapel 5 sind bekannte, sich über die Bogenbreite erstreckende und wahlweise mit Blas- oder Saugluft beaufschlagbare vordere Bogenhochhalter angeordnet. Die vorderen Bogenhochhalter sind zur Horizontalen in einem spitzen Winkel in den Bereich des Auslegerstapel 5 hineinragend geneigt angeordnet. Dabei sind die vorderen Bogenhochhalter aus einer Warteposition im Vorderkantenbereich außerhalb des Auslegerstapels 5 direkt in den Stapelbereich unterhalb der ankommenden Greifersysteme 5 bewegbar und mit den ankommenden Bogenmaterialien 2 zur Bildung einer Hilfsstapels absenkbar.The sheet material 2 arriving in the conveying direction 9 is in in a known manner, braked by a sheet brake device 7 and on the boom stack 5 against leading edge stops 11 stored. Parallel to the side frames of the boom 1 are swiveling guides, for example angle rails, for receiving an auxiliary stacking pad 12, for example a board or a rake. The auxiliary stack pad 12 can be fed horizontally in the insertion direction 13 or removable against the insertion direction 13. To the Purpose of taking test sheets or to form the Auxiliary stacks in the boom stack 5 are known, about the Arc width and optionally with blowing or suction air loadable front bow support arranged. The front bow brackets are horizontal in one acute angle protruding into the area of the boom stack 5 arranged inclined. Here are the front bow brackets from a waiting position in the leading edge area outside the delivery stack 5 directly into the stack area below the incoming gripper systems 5 movable and with the incoming sheet materials 2 to form an auxiliary stack lowered.

Im Bereich der Vorderkante des Auslegerstapels 5, speziell im Bereich des Hauptstapels, ist unterhalb der Führungen für die Hilfsstapelunterlage 12 zumindest über die Formatbreite eine Traverse 15 angeordnet, welche bevorzugt lösbar am Auslegergestell beidseitig befestigt ist. Der Auslegerstapel 5 weist weiterhin eine Stapeltragplatte 14 auf, welche eine Palette 19 mit den übereinander gestapelten Bogenmaterialien 2 aufnimmt. Bevorzugt weist die Stapeltragplatte 14 Anschläge 18 auf, gegen die die Palette 19 ausgerichtet ist.In the area of the front edge of the boom stack 5, especially in the Area of the main stack, is below the guides for the Auxiliary stacking pad 12 at least over the format width one Traverse 15 arranged, which is preferably releasably on the boom frame is attached on both sides. The boom stack 5 has furthermore a stack support plate 14, which is a pallet 19 records with the stacked sheet materials 2. The stack support plate 14 preferably has stops 18 against which the pallet 19 is aligned.

An der Stapeltragplatte 14 sowie an der Traverse 15 ist wenigstens eine, bevorzugt sind zwei längenveränderbare Kantenführungseinrichtungen 16 (fluchtend) nebeneinander angeordnet. Jede Kantenführungseinrichtung 16 ist parallel in einem festgelegten Abstand 20 der Vorderkante 21 des durch das Bogenmaterial 2 gebildeten Hauptstapels als Teil des Auslegerstapels 5 benachbart zugeordnet.
Beim Absenken oder Auffahren der Stapeltragplatte 14 mittels einer Stapelhubeinrichtung ist jede Kantenführungseinrichtung 16 zur vertikalen Bewegung der Stapeltragplatte 14 in ihrer Länge veränderbar. Bevorzugt ist die Längenänderung jeder Kantenführungseinrichtung 16 synchron zur vertikalen Bewegung der Stapeltragplatte 14 realisierbar.At least one, preferably two, length-adjustable edge guiding devices 16 (aligned) are arranged next to one another on the stack support plate 14 and on the cross member 15. Each edge guide device 16 is assigned in parallel at a fixed distance 20 to the front edge 21 of the main stack formed by the sheet material 2 adjacent as part of the delivery stack 5.
When the stack support plate 14 is lowered or opened by means of a stack lifting device, each edge guide device 16 can be changed in length for the vertical movement of the stack support plate 14. The change in length of each edge guide device 16 can preferably be implemented synchronously with the vertical movement of the stack support plate 14.

Um eine Lageveränderung des gestapelten Bogenmaterials 2 zu vermeiden ist die Kantenführungseinrichtung 16 in einem geringfügigen Abstand 20 zur Vorderkante 21 des Hauptstapels angeordnet. Die Größe des Abstandes 20 ist derart ausführbar, dass möglichst eine die Lage des Bogenmaterials 2 beeinträchtigende Reibung zwischen dem Bogenmaterial 2 im Bereich der Vorderkante 21 und jeder Kantenführungseinrichtung 16 beim Absenken des Hauptstapels zu vermeiden ist.To change the position of the stacked sheet material 2 avoid the edge guide device 16 in one slight distance 20 to the front edge 21 of the main stack arranged. The size of the distance 20 can be carried out in such a way that as far as possible impairing the position of the sheet material 2 Friction between the sheet material 2 in the area of Front edge 21 and each edge guide 16 at Avoid lowering the main stack.

In einer Ausbildung ist die Kantenführungseinrichtung 16 aus wenigstens einem vorzugsweise unter Zugspannung stehenden, aufwickelbaren Bandmaterial gebildet. In einer alternativen Ausbildung weist die Kantenführungseinrichtung 16 wenigstens ein unter Zugspannung stehendes, aufwickelbares Seil oder einen entsprechenden Gurt auf.
Bevorzugt weist jede Kantenführungseinrichtung 16 eine an der Stapeltragplatte 14 angeordnete Aufwickelvorrichtung 17 auf. Alternativ kann die Aufwickelvorrichtung 17 auch an der Traverse 15 angeordnet sein. Die Aufwickelvorrichtung 17 ist dabei derart ausgebildet, dass das Bandmaterial ebenso abwickelbar ist.In one embodiment, the edge guiding device 16 is formed from at least one windable strip material that is preferably under tensile stress. In an alternative embodiment, the edge guide device 16 has at least one cable that can be wound up under tension, or a corresponding belt.
Each edge guide device 16 preferably has a winding device 17 arranged on the stack support plate 14. Alternatively, the winding device 17 can also be arranged on the cross member 15. The winding device 17 is designed such that the strip material can also be unwound.

In einer bevorzugten Ausbildung ist die Traverse 15 vom Auslegergestell trennbar und auf der Stapeltragplatte 14 lagegesichert ablegbar. Das in der Aufwickelvorrichtung 17 gelagerte Bandmaterial ist in dieser Ausbildung fest oder lösbar mit der Traverse 15 verbunden.
Beim Ablegen der Traverse 15 auf der Stapeltragplatte 14 wickelt die Aufwickeleinrichtung 17 das Bandmaterial, vorzugsweise mittels Federkraft, auf. Dies gilt auch in der Ausbildung in der die Kantenführungseinrichtung 16 bzw. das Bandmaterial lösbar von der gestellfest verbleibenden Traverse 15 trennbar ist.In a preferred embodiment, the cross member 15 can be separated from the cantilever frame and can be placed on the stacking support plate 14 in a secured manner. In this embodiment, the strip material stored in the winding device 17 is fixedly or releasably connected to the cross member 15.
When the traverse 15 is placed on the stack support plate 14, the winding device 17 winds up the strip material, preferably by means of spring force. This also applies to the design in which the edge guide device 16 or the strip material can be detachably separated from the cross member 15 which remains fixed to the frame.

Die Erfindung ist nicht auf die Anordnung wenigstens einer Kantenführungseinrichtung 16 in Zuordnung zu einer Vorderkante 21 des Auslegerstapels 5 beschränkt. Vielmehr ist die Kantenführungseinrichtung 16 in Einzel- oder Mehrfachanordnung (fluchtend) wenigstens einer Seitenkante und/oder der Hinterkante des durch übereinander gestapelte Bogenmaterialien 2 gebildeten Hauptstapels parallel benachbart zuordbar.The invention is not based on the arrangement of at least one Edge guide device 16 in association with a leading edge 21 of the boom stack 5 limited. Rather, it is Edge guide device 16 in single or multiple arrangement (aligned) at least one side edge and / or the Trailing edge of sheet materials stacked on top of each other 2 formed main stack parallel adjacent.

Bei Zuordnung der Kantenführungseinrichtung 16 im Bereich der Seitenkanten und/oder Hinterkante des Auslegerstapels 5 ist zusätzlich zu berücksichtigen, dass unterschiedliche Bogenformate zu verarbeiten sind. Hierzu sind die eingesetzten Traversen 15 und die Kantenführungseinrichtungen 16 bevorzugt formatvariabel am Auslegergestell oder der Stapeltragplatte 14 oder an der Palette 19 angeordnet.When assigning the edge guide device 16 in the area of Side edges and / or rear edge of the boom stack 5 is additionally take into account that different sheet formats are to be processed. Here are the ones used Trusses 15 and the edge guide devices 16 are preferred variable in format on the jib frame or the stacking support plate 14 or arranged on the pallet 19.

Generell ist die Aufwickelvorrichtung 17 für die Kantenführungseinrichtung 16 wahlweise an der Stapeltragplatte 14 (im Bereich der Seiten- und Hinterkanten auch an der Palette 19) oder an der Traverse 15 anordbar.Generally, the winder 17 is for the edge guide 16 optionally on the stack support plate 14 (in Area of the side and rear edges also on the pallet 19) or can be arranged on the traverse 15.

In einer weiteren Ausbildung sind die übereinander gestapelten Bogenmaterialien 2 des Hauptstapels aus der im wesentlichen horizontalen Stapelebene in Förderrichtung 9, einer benachbarten vertikalen Kantenführungseinrichtung 16, der Vorderkante zugewandt, schwenkbar. Diese Schwenkbarkeit des Hauptstapels ist beispielsweise derart realisierbar, indem die Stapeltragplatte 14 mittels einer zumindest beim Stapelabsenken auf die Stapelhubeinrichtung wirkende Betätigungseinrichtung aus der horizontalen Ebene geneigt schwenkbar ist. Dazu ist beispielsweise die Stapeltragplatte 14 in vertikaler Richtung durch ausschließlich die der Hinterkante des Auslegerstapels 5 zugeordneten Zugmittel der Stapelhubeinrichtung um einen definierten Betrag anhebbar, so dass die Stapeltragplatte 14 (mit Auslegerstapel 5) in Richtung der der Vorderkante des Auslegerstapels 5 zugeordneten Kantenführungseinrichtung 16 geneigt ist.
In einer weiteren Ausbildung ist auf der Stapeltragplatte 14 im Bereich der Hinterkante des Auslegerstapels 5 (vor der Stapelbildung) wenigstens ein Keil ablegbar, welcher unter die Palette 19 greift und somit die Palette 19 in Förderrichtung 9 neigt. Dadurch ist der Auslegerstapel 5 gegen die Kantenführungseinrichtung 16 an der Vorderkante geringfügig geneigt.
In einer weiteren Ausbildung ist an der Stapeltragplatte 14 im Bereich der Hinterkante des Auslegerstapels 5 eine Kippeinrichtung angeordnet, die mittels einer Betätigungseinrichtung, beispielsweise pneumatisch oder hydraulisch, auf die Palette 19 im Bereich der Hinterkante wirkt und den Auslegerstapel 5 gegen die Kantenführungseinrichtung 16 neigt.
Die Neigung des Auslegerstapels 5 ist derart zu realisieren, dass die Kantenführung möglichst berührungslos erfolgt und eine mögliche Auslenkung der Kantenführungseinrichtung 16 aus der Vertikalen durch Kontakt mit dem Bogenmaterial 2 vermieden wird. In a further embodiment, the sheet materials 2 of the main stack which are stacked one above the other can be pivoted out of the essentially horizontal stacking plane in the conveying direction 9, an adjacent vertical edge guide device 16, facing the front edge. This pivotability of the main stack can be realized, for example, in that the stack support plate 14 can be tilted out of the horizontal plane by means of an actuating device which acts on the stack lifting device at least when the stack is being lowered. For this purpose, for example, the stack support plate 14 can be raised in the vertical direction by only a defined amount by means of the traction means of the stack lifting device assigned to the rear edge of the delivery stack 5, so that the stack support plate 14 (with delivery stack 5) is inclined in the direction of the edge guide device 16 assigned to the front edge of the delivery stack 5 ,
In a further embodiment, at least one wedge can be placed on the stack support plate 14 in the area of the rear edge of the delivery stack 5 (before the stack formation), which wedge engages under the pallet 19 and thus tilts the pallet 19 in the conveying direction 9. As a result, the boom stack 5 is slightly inclined against the edge guide device 16 on the front edge.
In a further embodiment, a tilting device is arranged on the stack support plate 14 in the area of the rear edge of the delivery stack 5, which acts on the pallet 19 in the area of the rear edge by means of an actuating device, for example pneumatically or hydraulically, and inclines the delivery stack 5 against the edge guide device 16.
The inclination of the delivery stack 5 is to be realized in such a way that the edge guidance takes place as contactlessly as possible and a possible deflection of the edge guidance device 16 from the vertical through contact with the sheet material 2 is avoided.
