Abstract

The machine has stops and high holders for the leading and trailing edges of the sheets. The front sheet high holders can be moved into the stack area above the main stack (1) at an angle (`) inclined to the horizontal. Lower stops (15) fixed on a vertically movable support (12) extending stretched beneath the insert plane of a second stack support (2) are movably guided on the stops (14) which are fixed on the cross beam (10). The support (12) has at the free ends wedges (16) projecting into the stack area with the wedge face facing the main stack and directed, seen in the conveyor direction, inclined upwards into the insert plane of the secondary stack support. A coupling rod movable by a work cylinder (19) is connected to ternary members parallel to the side of the support (12) remote from the stack area. These ternary members act in turn on the rear sheet high holders (17) to move same horizontally into a position between the trailing edges of the upper sheets of the main stack. The rear sheet high holders can be moved through engagement of the secondary stack support (2) with the wedges and the resulting lift of the support (12) up to above the main stack (1).

Description

Die Erfindung betrifft eine weitere Ausbildung eines Verfahrens und einer Vorrichtung zur exakten Trennung von Haupt- und Hilfsstapel bei Non-Stop-Auslegern in bogenverarbeitenden Druckmaschinen oder dergleichen, nach dem deutschen Hauptpatent Nr. P 43 17 357.The invention relates to a further embodiment of a method and a device for the exact separation of main and auxiliary stacks in non-stop delivery in sheet-processing printing machines or the like, according to the German main patent No. P 43 17 357.

Aus der DE 2 301 840 A1 ist eine Bogenauslegevorrichtung bekannt, bei der im Bereich der Bogenvorderkante des abzulegenden Bogens Auflagefinger in diesem Bereich über dem Hauptstapel einschwenkbar sind. In einer weiteren Ausbildung ist ein Hilfsstapeltisch zum Zwecke des Stapelwechsels über den Hauptstapel einschiebbar und auf der den Auflagefingern gegenüberliegenden Seite sind über dem Stapel mittels Arbeitszylinder einbringbare Hochhalter angeordnet.From DE 2 301 840 A1 a sheet delivery device is known in which, in the area of the sheet leading edge of the sheet to be deposited, support fingers can be swung in in this area above the main stack. In a further embodiment, an auxiliary stacking table can be inserted over the main stack for the purpose of changing the stack, and on the side opposite the support fingers, upright holders which can be inserted by means of working cylinders are arranged above the stack.

Eine Vorrichtung zum zwischenzeitlichen Auffangen von Bogen speziell zum Halten der Bogenhinterkante ist aus der DE 3 112 558 C2 bekannt. Als Stützmittel für die Bogenhinterkante dienen dabei Winkel stützen, die drehbar an einem Halter im Bereich der Bogenbremse angeordnet sind. Die Winkelstützen besitzen unterschiedliche Schenkellängen und können bei Auflage mehrerer Bogen, bedingt durch das Gewicht der Bogen, wegklappen, so daß der entstandene Teilstapel auf das inzwischen eingeschobene Zwischenstapelbrett gelangt.A device for the interim collection of sheets especially for holding the trailing edge of the sheet is known from DE 3 112 558 C2. Angle supports serve as support means for the trailing edge of the arch, which are rotatably arranged on a holder in the region of the arch brake. The angle supports have different leg lengths and can fold away when several sheets are placed due to the weight of the sheets, so that the resulting partial stack reaches the intermediate stacking board that has now been inserted.

Gemäß der DE 3 112 672 C1 ist ein Anschlag für die Bogenhinterkante bekannt, der als Traverse ausgebildet ist und mit einer an der Bogenbremse befestigten Stützschere in Verbindung mit einer Zwischenstapeleinrichtung auf- und abbeweglich angeordnet ist.According to DE 3 112 672 C1, a stop for the trailing edge of the sheet is known, which is designed as a traverse and is arranged so that it can move up and down with a pair of supporting scissors attached to the sheet brake in conjunction with an intermediate stacking device.

Aus der DE 3 937 945 C2 ist eine Bogenhinterkantenfangeinrichtung für Ausleger mit einer Non-Stop-Hilfsstapeleinrichtung bekannt. Unterhalb der Saugwalze sind steuerbare Fangfinger zwischen Hinterkantenanschlägen angeordnet die mittels Zahnstange und Ritzel von einem pneumatischen Arbeitszylinder gemeinsam in einer Ebene beweglich sind.DE 3 937 945 C2 discloses a sheet trailing edge catching device for cantilevers with a non-stop auxiliary stacking device. Controllable catch fingers are arranged between the rear edge stops below the suction roller and can be moved together in one plane by means of a rack and pinion by a pneumatic working cylinder.

Bei den oben genannten Lösungen nach DE 2 301 840 A1 und DE 3 112 558 C2 läßt es sich nicht vermeiden, daß ankommende Bogen in die Maschine, in Richtung Bogenaufgang zurückrutschen oder zwischen Hinterkantenanschlag und Hilfsstapel klemmen oder deformiert werden. Nach der DE 3 112 672 C1 wird das Zurückrutschen der ankommenden Bogen verhindert, jedoch kann der Anschlag nicht die Aufgabe der exakten Trennung der Bogen von Haupt- und Hilfsstapel lösen. Gemäß DE 3 937 945 C2 wird das Zurückrutschen der ankommenden Bogen verhindert, jedoch ist hierbei eine aufwendige Ausbildung zum Trennen von Haupt- und Hilfsstapel erforderlich. Aufspießvorgänge von Bogen im Bereich der Hinterkante werden beim Einschieben des Rechens vermieden, jedoch wird die Gefahr lediglich auf die horizontale Hin- und Herbewegung der Fangfinger verlagert. Insbesondere bei höheren Maschinengeschwindigkeiten sind Aufspießvorgänge durch die Fangfinger nicht zu vermeiden. In der DE 4 011 286 A1 ist eine Einrichtung beschrieben, deren Fangfinger als Sauggreifer ausgebildet sind. An der Oberseite der Sauggreifer werden die abgelegten Bogen mittels Saugdüse angesaugt und zur Bogenstraffung werden die Sauggreifer um einen definierten Betrag zurückgezogen. Die Verwendung von Sauggreifern an der Bogenvorderkante in Auslegern ist an sich bereits aus der DE-PS 921 154 bekannt.With the above-mentioned solutions according to DE 2 301 840 A1 and DE 3 112 558 C2, it cannot be avoided that incoming sheets slip back into the machine, in the direction of the sheet emergence, or jam or become deformed between the trailing edge stop and the auxiliary stack. According to DE 3 112 672 C1, the incoming sheets are prevented from slipping back, but the stop cannot solve the task of exactly separating the sheets from the main and auxiliary stacks. According to DE 3 937 945 C2, the incoming sheets are prevented from slipping back, but this requires complex training for separating the main and auxiliary stacks. Spearings of sheets in the area of the rear edge are avoided when the rake is pushed in, but the danger is only shifted to the horizontal back and forth movement of the catch fingers. In particular at higher machine speeds, skewing operations by the catching fingers cannot be avoided. DE 4 011 286 A1 describes a device whose catch fingers are designed as suction pads. At the top of the suction pads, the deposited sheets are sucked in by means of a suction nozzle and the suction pads are pulled back by a defined amount to tighten the sheets. The use of suction pads on the sheet leading edge in jibs is known per se from DE-PS 921 154.

Aufgabe der Erfindung ist es, eine Lösung zur exakten Stapeltrennung von Haupt- und Hilfsstapel an der Bogenhinterkante zu entwickeln.The object of the invention is to develop a solution for the exact stack separation of main and auxiliary stacks on the trailing edge of the sheet.

Die Erfindung löst diese Aufgabe durch die Merkmale nach dem Kennzeichen der Patentansprüche 1 und 2. Die erfindungsgemäße Lösung gewährleistet den Non-Stop-Betrieb bei maximaler Maschinengeschwindigkeit. Beispielsweise bei einer Geschwindigkeit von 4 Bogen/Sekunde wird während des Fortdruckes der Hauptstapel ausgefahren. Dies erhöht die Effektivleistung der Druckmaschine und wirkt sich positiv auf die Druckqualität aus, da Störungen der Farb-/Feuchtmittelbalance vermieden werden und zum Stapelwechsel muß die Druckmaschine nicht während des Fortdruckes in ihrer Geschwindigkeit reduziert werden. Der Bogenausleger ist mit vorderen Bogenhochhaltern, einem absenkbaren Hilfsstapel und einer Trennvorrichtung am hinteren Bogenanschlag zur exakten Trennung von Haupt- und Hilfsstapel bei Rechen-oder Bretteinschub ausgerüstet. Haupt- und Hilfsstapel haben separate Antriebe, die über vier Rollenketten die daran befestigte Stahlplatte oder den Stahlrahmen heben oder senken. Bekannte seitlich angeordnete Winkel schienen schwenken seitlich ein bzw. aus. Durch die Kombination von feststehenden hinteren oberen Anschlägen und vertikal beweglichen hinteren unteren Anschlägen wird gewährleistet, daß die ankommenden Bogen nicht in Richtung Bogenaufgang in die Maschine zurückrutschen können. Die vorderen Bogenhochhalter werden in einem Winkel zur Horizontalen geneigt in den Stapelbereich bewegt und bei Bedarf mit Saugluft beaufschlagt. Mittels Saugluft wird der unterste Bogen des Hilfsstapels für einen bestimmten Zeitraum festgehalten (Sauggreifer). Dies ist insbesondere bei Verarbeitung von Bedruckstoffen mit einem Flächengewicht < 200g/M 2 von Vorteil. Diese Bedruckstoffe neigen aufgrund ihrer geringeren Eigensteifigkeit beim Einschieben des Rechens/Stapelbrettes zum Einrollen bzw. zum Deformieren in Richtung der Hinterkantenanschläge. Die hinteren Bogenhochhalter werden beim Einschieben des Stapelbrettes oder Rechens in den vorhandenen Stapel eingeführt und trennen den Stapel in Haupt- und Hilfsstapel. Da die weiter abzulegenden Bogen an den vorderen Bogenhochhaltern durch ihr Eigengewicht oder durch Saugluft (Sauggreifer) gehalten werden, können diese beim Einschieben des Stapelbrettes oder Rechens nicht in Richtung hintere Anschläge einrollen, verschoben oder deformiert werden. Die Erfindung soll an einem Ausführungsbeispiel näher erläutert werden.The invention solves this problem by the features according to the characterizing part of claims 1 and 2. The solution according to the invention ensures non-stop operation at maximum machine speed. For example, at a speed of 4 sheets / second, the main stack is extended during printing. This increases the effective performance of the printing press and has a positive effect on the print quality, since disturbances in the ink / fountain solution balance are avoided and the speed of the printing press does not have to be reduced during the printing process to change the batch. The sheet delivery is equipped with front sheet holders, a lowerable auxiliary stack and a separator at the rear sheet stop for exact separation of the main and auxiliary stacks when inserting rakes or boards. The main and auxiliary stacks have separate drives that raise or lower the steel plate or steel frame attached to them via four roller chains. Known laterally arranged angles seemed to pivot in or out laterally. The combination of fixed rear upper stops and vertically movable rear lower stops ensures that the incoming sheets cannot slip back into the machine in the direction of the sheet emergence. The front sheet brackets are inclined at an angle to the horizontal and moved into the stacking area and, if necessary, supplied with suction air. The bottom sheet of the auxiliary stack is held by suction air for a certain period of time (suction pad). This is particularly advantageous when processing substrates with a basis weight <200g / M 2 . Due to their lower inherent rigidity when inserting the rake / stacking board, these substrates tend to curl or deform in the direction of the rear edge stops. The rear sheet holders are inserted into the existing stack when the stacking board or rake is inserted and separate the stack in main and auxiliary stacks. Since the sheets to be deposited further are held on the front sheet holders by their own weight or by suction air (suction gripper), they cannot be rolled, shifted or deformed in the direction of the rear stops when the stacking board or rake is inserted. The invention will be explained in more detail using an exemplary embodiment.

In Fig. 1 ist ein mittels Kettensystem 8 und Greifersystem 6 in Förderrichtung 18 zugeführter Bogen 7 in einem Bogenausleger einer Druckmaschine dargestellt. Die von der Druckmaschine ankommenden Bogen 7 werden über einen Hauptstapel 1 transportiert und auf diesem abgelegt. Jeder Bogen 7 wird dabei mit der Bogenvorderkante gegen an sich bekannte nebeneinander angeordnete, vordere Anschläge 3 abgelegt. Parallel zu den Seitenteilen des Auslegers sind einschwenkbare Winkel schienen 13 zur Aufnahme eines Stapelbrettes 2 angeordnet. Zum Zwecke der Entnahme von Probebogen oder zur Bildung eines Hilfsstapels 5 sind ebenfalls bekannte, sich über die Bogenbreite erstreckende und wahlweise mit Saugluft beaufschlagbare, vordere Bogenhochhalter 4 angeordnet. Die Bogenhochhalter 4 sind zu einer Horizontalen 24 in einem spitzen Winkel a in den Stapelbereich geneigt. Im Bereich der Hinterkante der zu einem Stapel 1 abgelegten Bogen 7 ist dem Stapel 1 eine formatabhängig einstellbare Bogenbremseinrichtung 9 vorgeordnet. Unterhalb der Bogenbremse 9 ist an dieser eine querverlaufende Traverse 10 befestigt. An der Traverse 10 sind parallel zur Hinterkante des abgelegten Bogens 7 mehrere obere Anschläge 14 mit Abstand nebeneinander angeordnet. Die Anschläge 14 erstrecken sich dabei vertikal nach oben zwischen die Bogenbremseinrichtung 9. Unterhalb der Traverse 10 sind parallel dazu ein Querstab 11 und ein Träger 12 angeordnet, die über mehrere Koppeln 20 drehbeweglich mit der Traverse 10 verbunden sind, derart, daß Träger 12 und Querstab 11 zur feststehenden Traverse 10 vertikal auf- und abbeweglich sind. Zwischen Traverse 10 und Träger 12 sind zwei zugbeanspruchte Federn 25 angeordnet, die die Aufwärtsbewegung von Träger 12 und Querstab 11 unterstützen. Der Träger 12 ist breiter als die maximale Bogenbreite ausgeführt, jedoch kleiner als der Abstand zwischen den beiden Winkel schienen 13. An den freien Enden des Trägers 12 sind Keile 16 befestigt und über die Bogenbreite sind mehrere untere Anschläge 15 mit Abstand nebeneinander am Träger 12 angeordnet. Mindestens zwei der unteren Anschläge 15 sind mit den oberen Anschlägen 14, z.B. in einer Längsnut, derart geführt, daß eine Relativbewegung (Translation) der unteren Anschläge 15 zu den feststehenden oberen Anschlägen 14 möglich ist. Die unteren Anschläge 14 erstrecken sich nach unten bis auf die Höhe des Hauptstapels 1. An dem Träger 12 sind an der dem Stapelbereich abgewandten Seite zwei ternäre Glieder 21 drehbeweglich angelenkt, deren jeweiligen drei Drehgelenke mit einer parallel zum Träger 12 angeordneten Koppelstange 22, dem Träger 12 und hinteren Bogenhochhaltern 17 verbunden sind. Der Koppelstange 22 ist ein Pneumatik-Arbeitszylinder 19 vorgeordnet, der am Träger 12 fixiert und mit einer nicht weiter beschriebenen Luftversorgung verbunden ist. Die hinteren Bogenhochhalter 17 sind durch den Träger 12 hindurch geführt, so daß deren Spitzen in eingeschwenktem Zustand in den Stapel bereich zeigen. Im vorliegenden Beispiel sind die Bogenhochhalter 17 zusätzlich durch die unteren Anschläge 15 geführt. Zum Erkennen des einzuschiebenden Stapelbrettes 2 ist im Bereich der vorderen Anschläge 3 ein Sensor 23 angeordnet. Ebenso ist zum Erkennen der Auf- und Abwärtsbewegung von Querstab 11 und Träger 12 ein Sensor 26 im Bereich der Traverse 10 angeordnet.1 shows a sheet 7 fed in the conveying direction 18 by means of chain system 8 and gripper system 6 in a sheet delivery of a printing press. The sheets 7 arriving from the printing press are transported via a main stack 1 and placed thereon. Each sheet 7 is placed with the leading edge of the sheet against known front stops 3 arranged side by side. Parallel to the side parts of the boom, pivotable angle rails 13 are arranged for receiving a stacking board 2. For the purpose of taking out sample sheets or to form an auxiliary stack 5, known front sheet holders 4, which extend over the sheet width and can optionally be acted upon by suction air, are also arranged. The sheet support 4 are inclined to a horizontal 24 at an acute angle a in the stacking area. In the area of the rear edge of the sheets 7 deposited to form a stack 1, the stack 1 is preceded by a sheet brake device 9 which can be set depending on the format. A transverse traverse 10 is fastened to the latter below the sheet brake 9. On the crossmember 10, a plurality of upper stops 14 are arranged next to one another at a distance parallel to the rear edge of the deposited sheet 7. The stops 14 extend vertically upwards between the sheet braking device 9. Below the cross member 10, a cross bar 11 and a carrier 12 are arranged in parallel, which are rotatably connected to the cross member 10 via a plurality of couplers 20 such that the carrier 12 and cross bar 11 to the fixed cross member 10 are vertically up and down. Between the cross member 10 and the carrier 12, two tension-loaded springs 25 are arranged, which support the upward movement of the carrier 12 and the crossbar 11. The carrier 12 is made wider than the maximum arc width, but smaller than the distance between the two angles rails 13. Wedges 16 are fastened to the free ends of the carrier 12 and several lower stops 15 are arranged next to one another on the carrier 12 via the arc width . At least two of the lower stops 15 are connected to the upper stops 14, e.g. in a longitudinal groove, such that a relative movement (translation) of the lower stops 15 to the fixed upper stops 14 is possible. The lower stops 14 extend down to the height of the main stack 1. Two ternary links 21 are pivotally articulated on the support 12 on the side facing away from the stack area, the respective three rotary joints of which have a coupling rod 22, the support, arranged parallel to the support 12 12 and rear arch brackets 17 are connected. The coupling rod 22 is preceded by a pneumatic working cylinder 19, which is fixed to the carrier 12 and is connected to an air supply, which is not further described. The rear sheet holder 17 are passed through the carrier 12, so that their tips show in the pivoted state in the stack area. In the present example, the sheet support 17 are additionally guided through the lower stops 15. To detect the stacking board 2 to be inserted, a sensor 23 is arranged in the area of the front stops 3. Likewise, a sensor 26 is arranged in the area of the crossmember 10 in order to recognize the upward and downward movement of the crossbar 11 and the support 12.

Die Wirkungsweise ist wie folgt: In an sich bekannter Weise werden Bogen 7 von Greifersystem 6, das an einem Kettensystem 8 angelenkt ist in Förderrichtung 18 über eine Bogenbremse 9 geführt und auf einem Hauptstapel 1 abgelegt. Der Hauptstapel 1 liegt auf einem nicht dargestellten Ablegetisch auf, der entsprechend der wachsenden Stapelhöhe absenkbar ist. Hat der Hauptstapel 1 seine vorher bestimmte Höhe erreicht, wird bei laufendem Fortdruck ein Hilfsstapel 5 gebildet, damit der Hauptstapel 1 aus dem Auslegerbereich abtransportiert werden kann.The mode of operation is as follows: In a manner known per se, sheets 7 of the gripper system 6, which is articulated on a chain system 8, are guided in the conveying direction 18 via a sheet brake 9 and placed on a main stack 1. The main stack 1 lies on a storage table, not shown, which can be lowered in accordance with the increasing stack height. When the main stack 1 has reached its predetermined height, an auxiliary stack 5 is formed while the production is running so that the main stack 1 can be removed from the delivery area.

Zur Bildung des Hilfsstapels 5 werden die vorderen durch den Sensor 23 aktivierten Bogenhochhalter 4 beim Einlegen des leeren Stapelbrettes 2 herausgefahren, in eine Position die die vom Greifersystem 6 transportierten Bogen 7 im Bereich der Vorderkante stützt. Die Bogenhochhalter 4 sind in einem Winkel a von etwa 30 ° zur Horizontalen 24 in Richtung Stapelbereich geneigt und können wahlweise mit Saugluft (Sauggreifer) beaufschlagt werden. Die Verwendung als Sauggreifer empfiehlt sich bei leichten Bedruckstoffen mit einem Flächengewicht von < 200g/m2. Das Ansaugen des Bedruckstoffes auf die Bogenhochhalter 4 fixiert den unteren Bogen 7 des zu bildenden Hilfsstapels 5 auf den Hochhaltern 4 und verhindert das Zurückrutschen oder Einrollen des Bogens bei Stapelwechsel. Durch das Einschwenken der Bogenhochhalter 4 entsteht ein Freiraum zwischen Oberkante Hauptstapel 1 und Unterseite Hilfsstapel 5 zum Einlegen des leeren Stapelbrettes 2 entgegen der Förderrichtung 18 in Richtung auf die hinteren Anschläge 14, 15 (Endlage des Stapelbrettes 2). Trifft das in Winkel schienen 13 aufgenommene Stapelbrett 2 auf die schräg nach oben (in Richtung Greifersystem 6) gerichteten Keile 16, werden diese gemeinsam mit Träger 12 und Arbeitszylinder 19 senkrecht nach oben bewegt und somit auch die unteren Stapelanschläge 15. Die unterhalb des Stapelbrettes 2 angeordneten durch die unteren Anschläge 15 geführten hinteren Bogenhochhalter 17 wurden gleichzeitig mit dem Einschwenken der vorderen Bogenhochhalter 4 in den Auslegerbereich, hier den Hauptstapel 1, eingeschwenkt. Das Einschwenken erfolgt durch Beaufschlagung des Arbeitszylinders 19 mit Druckluft, ebenso sind die vorderen Bogenhochhalter 4 pneumatisch mit einem weiteren Arbeitszylinder gekoppelt. Durch die Aktivierung des Arbeitszylinders 19 wird die Koppelstange 22 parallel zum Träger 12 bewegt. Die Koppelstange 22 überträgt die Bewegung auf die ternären Glieder 21, welche um den jeweiligen Drehpunkt am Träger 12 verschwenken und die Bogenhochhalter 17 um den Bereich des Hauptstapels 1 bewegen. Jeder Hochhalter 17 verbleibt in seiner horizontalen Anordnung und bewegt sich zusätzlich vertikal, bedingt durch das Auftreffen des Stapelbrettes 2 an den Keilen 16. Das Bewegungsgesetz der Hochhalter 17 ist derart, daß diese in den Bereich des Hauptstapels 1 einschwenken und gleichzeitig eine Trennung von Hauptstapel 1 und Hilfsstapel 5 unter Verwendung eines Stapelbrettes 2 erfolgt. Dies erfolgt dadurch, daß zu Beginn der Einschwenkbewegung der Hochhalter 17 die oberen Bogen 7 des Hauptstapels 1 sich kurzzeitig auf die Spitzen der Hochhalter 17 auflegen und danach beim Hochbewegen der Hochhalter 17 und gleichzeitigen Absenken des Hauptstapels 1 auf dem Hauptstapel 1 abgelegt werden. Danach tragen die Spitzen des Hochhalters 17 den untersten Bogen 7 und alle zwischenzeitlich nachfolgenden Bogen 7 des Hilfsstapels 5, so daß das Stapelbrett 2 unter die hinteren unteren Anschläge 15 durchgeschoben werden kann. Die unteren Anschläge 15 liegen dabei auf dem Stapelbrett 2 auf und verhindern zusammen mit den eingeschwenkten Hochhaltern 17, das Zurückrutschen von Bogen 7 in Richtung Bogenaufgang. Nach erfolgter Stapeltrennung werden die hinteren Hochhalter 17 pneumatisch aus dem Stapelbereich zurückbewegt. Dies erfolgt unter Verwendung des Sensors 26 der die jeweilige Auf- und Abwärtsposition von Querstab 11 und Träger 12 erkennt. Wird der Hilfsstapel 5 entsprechend der wachsenden Stapelhöhe abgesenkt, bewegen sich der Träger 12 sowie die Keile 16, untere Anschläge 15 und hintere Bogenhochhalter 17 nach unten. Der Hauptstapel 1 ist inzwischen abtransportiert worden, der Ablegetisch wird an Rollenketten in die obere Ausgangsposition bewegt und übernimmt das Stapelbrett mit Hilfsstapel 5. Haupt- und Hilfsstapel 1, 5 haben separate Antriebe. Beim Ausheben des Hilfsstapels 5 schwenken die Winkel schienen 13 seitlich aus und fahren in die obere Ausgangsstellung. Das Stapelbrett 2 wird nicht herausgezogen, sondern trägt nun den Hauptstapel 1.To form the auxiliary stack 5, the front sheet retainers 4 activated by the sensor 23 are moved out when the empty stacking board 2 is inserted, into a position which supports the sheets 7 transported by the gripper system 6 in the region of the front edge. The sheet support 4 are inclined at an angle a of approximately 30 ° to the horizontal 24 in the direction of the stacking area and can optionally be supplied with suction air (suction gripper). Use as a suction pad is recommended for light substrates with a basis weight of <200g / m 2. The substrate is sucked onto the sheet holder 4 the lower sheet 7 of the auxiliary stack 5 to be formed on the holder 4 and prevents the sheet from sliding back or rolling when the stack is changed. By pivoting the sheet support 4 there is a free space between the upper edge of the main stack 1 and the underside of the auxiliary stack 5 for inserting the empty stacking board 2 against the conveying direction 18 in the direction of the rear stops 14, 15 (end position of the stacking board 2). If the stacking board 2 received at an angle 13 meets the wedges 16 directed obliquely upwards (in the direction of the gripper system 6), these are moved vertically upwards together with the carrier 12 and the working cylinder 19 and thus also the lower stacking stops 15. The ones below the stacking board 2 Rear arch support 17 arranged through the lower stops 15 were pivoted into the delivery area, here the main stack 1, simultaneously with the pivoting of the front arch support 4. The pivoting-in is carried out by applying compressed air to the working cylinder 19, and the front arch brackets 4 are also pneumatically coupled to a further working cylinder. By activating the working cylinder 19, the coupling rod 22 is moved parallel to the carrier 12. The coupling rod 22 transmits the movement to the ternary members 21, which pivot about the respective pivot point on the carrier 12 and move the sheet support 17 around the area of the main stack 1. Each holder 17 remains in its horizontal arrangement and additionally moves vertically, due to the impact of the stacking board 2 on the wedges 16. The law of movement of the holder 17 is such that they pivot into the area of the main stack 1 and at the same time separate from the main stack 1 and auxiliary stack 5 is carried out using a stacking board 2. This is done in that at the beginning of the pivoting-in movement of the holder 17, the upper sheets 7 of the main stack 1 lie briefly on the tips of the holder 17 and are then placed on the main stack 1 when the holder 17 is moved up and the main stack 1 is simultaneously lowered. Thereafter, the tips of the bracket 17 carry the bottom sheet 7 and all sheets 7 of the auxiliary stack 5 following in the meantime, so that the stacking board 2 can be pushed under the rear lower stops 15. The lower stops 15 rest on the stacking board 2 and, together with the pivoted-in upholders 17, prevent the sheet 7 from sliding back in the direction of the sheet emergence. After the stack has been separated, the rear upholders 17 are pneumatically moved back out of the stacking area. This is done using the sensor 26 which detects the respective up and down positions of the cross bar 11 and the support 12. If the auxiliary stack 5 is lowered in accordance with the increasing stack height, the carrier 12 as well as the wedges 16, lower stops 15 and rear arch support 17 move downward. The main stack 1 has now been removed, the depositing table is moved to the upper starting position on roller chains and takes over the stacking board with the auxiliary stack 5. The main and auxiliary stacks 1, 5 have separate drives. When lifting the auxiliary stack 5, the angle rails 13 pivot laterally and move into the upper starting position. The stacking board 2 is not pulled out, but now carries the main stack 1.
