Description

Die Erfindung betrifft ein Stapelhandling einer Druckmaschine zum Bedrucken einer Bogenvorderseite und zum Bedrucken einer Bogenrückseite.The invention relates to a stack handling of a printing machine for printing on a sheet front and for printing on the back of a sheet.

Es sind Druckmaschinen allgemein bekannt (EP 0 512 549), bei denen zum Bedrucken der Bogenvorderseite und zum nachfolgenden Bedrucken der Bogenrückseite ein zweimaliger Bogendurchlauf und ein Wenden des Stapels vor dem zweiten Bogendurchlauf zum Bedrukken der Bogenrückseite erforderlich ist.
Nachteilig ist der hohe Aufwand für den zweiten Bogendurchlauf und insbesondere für das Wenden des Bogenstapels mit einer zusätzlichen Stapelwendeeinrichtung.Printing presses are generally known (EP 0 512 549), in which a double pass through the sheet and a reversal of the stack before the second pass through the sheet are required to print on the back of the sheet for printing on the front of the sheet and for subsequent printing.
The high outlay for the second sheet pass and in particular for turning the sheet stack with an additional stack turning device is disadvantageous.

Es sind auch Druckmaschinen bekannt (DD 54 703), bei denen der zu bedruckende Bogen zuerst auf der Bogenvorderseite bedruckt, in der Druckmaschine gewendet, die Bogenrückseite bedruckt und danach mit der Bogenrückseite nach oben auf einen Auslagebogenstapel abgelegt wird.
Für kleine und/oder Kompaktmaschinen und/oder Druckmaschinen mit Bebilderung der Druckplatte in der Druckmaschine ist der Aufwand für eine Wendeeinrichtung relativ hoch und damit nachteilig.Printing machines are also known (DD 54 703), in which the sheet to be printed is first printed on the front side of the sheet, turned in the printing press, printed on the back side of the sheet and then placed on a delivery sheet stack with the back side up.
For small and / or compact machines and / or printing machines with imaging of the printing plate in the printing machine, the expenditure for a turning device is relatively high and therefore disadvantageous.

Das Bedrucken einer Bogenvorderseite und das Bedrucken einer Bogenrückseite eines von einem Anlegerbogenstapel über mindestens einen direkt oder indirekt mit mindestens einem einfärbbaren Drückformzylinder zusammenwirkenden Bogenführungszylinder zu einem Auslagebogenstapel geförderten Bogens ist auch dadurch möglich. daß der zu bedruckende Bogen vom Anlegerbogenstapel entnommen, dem Bogenführungszylinder zum Bedrucken der Bogenrückseite zugeführt, die Bogenrückseite bedruckt, der bedruckte Bogen mit einer Bogentransportrichtung zum Auslagebogenstapel entgegen der Bogenlaufrichtung zum Bogenführungszylinder transportiert, auf den relativ zur Bogenlaufrichtung in der gleichen Ebene vor dem Anlegerbogenstapel angeordneten Auslagebogenstapel mit der bedruckten Bogenrückseite nach oben abgelegt und der Auslagebogenstapel zum Nachfolgedruck der Bogenvorderseite in die Position des Anlegerbogenstapels verbringbar ist. Printing on a sheet front and printing on a sheet back one of a stack of feeders via at least one directly or indirectly with at least one inkable impression cylinder interacting sheet guide cylinder into one Delivery sheet stacks of conveyed sheets are also possible. that the one to be printed Sheet taken from the stack of feeder sheets, the sheet guide cylinder for printing on the Back of sheet fed, the back of sheet printed, the printed sheet with a sheet transport direction to the delivery sheet stack against the sheet running direction to the sheet guide cylinder transported on the relative to the sheet running direction in the same plane Delivery sheet stack with the printed sheet back arranged in front of the stack of feed sheets placed upwards and the delivery sheet stack for subsequent printing of the sheet front can be brought into the position of the stack of feeder sheets.

Das Stapelhandling für Bogendruckmaschinen zum Bedrucken einer Bogenvorderseite und nachfolgendem Bedrucken einer Bogenrückseite wird anhand der in Fig. 1 dargestellten Bogendruckmaschine beschrieben.
Die Druckmaschine enthält einen Anlegerbogenstapel 1, Förderelemente 2, weitere Förderelemente 3, einen als Druckzylinder ausgebildeten Bogenführungszylinder 4, der mit zwei Offsetzylindern 5 zusammenwirkt, wobei jedem Offsetzylinder ein Druckformzylinder 6 mit zwei Farb-/Feuchtwalzen 7 zugeordnet ist, zusätzliche Förderelemente 9 und einen Auslagebogenstapel 11.
Der zu bedruckende bogen 12 wird zuerst vom Anlegerbogenstapel 1 in Richtung des Bogenführungszylinders 4 transportiert, diese Richtung wird mit Bogenlaufrichtung 14 bezeichnet. Die Übergabe der bedruckten Bogen vom Bogenführungszylinder 4 an die nachfolgenden zusätzlichen Förderelemente 9 erfolgt entgegen der Bogenlaufrichtung 14, diese Richtung wird nachfolgend Bogentransportrichtung 15 genannt.
Durch die Änderung der Bogenbewegungsrichtung - Bogenlaufrichtung 14 in Bogentransportrichtung 15 - ist der Auslagebogenstapel 11 in Bogenlaufrichtung 14 gesehen, vor dem Anlegerbogenstapel 1 angeordnet. The stack handling for sheet-fed printing machines for printing on a sheet front and subsequent printing on a sheet back is described with reference to the sheet-fed printing machine shown in FIG. 1.
The printing press contains a feeder sheet stack 1, conveying elements 2, further conveying elements 3, a sheet guiding cylinder 4 designed as a printing cylinder, which cooperates with two offset cylinders 5, with each offset cylinder being assigned a printing form cylinder 6 with two inking / dampening rollers 7, additional conveying elements 9 and a delivery sheet stack 11.
The sheet 12 to be printed is first transported from the feeder sheet stack 1 in the direction of the sheet guide cylinder 4, this direction is referred to as sheet travel direction 14. The transfer of the printed sheets from the sheet guide cylinder 4 to the subsequent additional conveying elements 9 takes place counter to the sheet travel direction 14, this direction is referred to below as the sheet transport direction 15.
Due to the change in the direction of sheet movement - sheet travel direction 14 in sheet transport direction 15 - the delivery sheet stack 11 is seen in the sheet travel direction 14, arranged in front of the feeder sheet stack 1.

Des weiteren ist der Anlegerbogenstapel 1 und der Auslagebogenstapel 11 in gleicher Stapelebene 10 angeordnet.
Die Bogenstapel 1; 11 sind jeweils einem Stapeltransportwagen 16 zugeordnet, die auf der Stapelebene 10 bewegbar sind.
Der vom Anlegerbogenstapel 1 zu dem Bogenführungszylinder 4 geförderte Bogen wird aufgrund dieses Maschinenschemas, bezogen auf die Lage des Bogens auf dem Anlegerbogenstapel 1 zuerst auf der Bogenrückseite bedruckt und mit der bedruckten Bogenrückseite nach oben auf dem Auslagebogenstapel 11 abgelegt. Dies bietet die Möglichkeit, den Auslagebogenstapel 11 durch Verschieben oder durch Drehen um 180° und Verschieben in die Position des Anlagebogenstapels 1 zu bringen und sofort den Nachfolgedruck der Vorderseite des Bogens in einem zweiten Bogendurchlauf ohne Stapelwendung zu beginnen. Das Drehen des Stapels bietet den Vorteil, daß die für einen qualitativ hochwertigen Druck relevante Anlagekante immer, d.h. beim Bedrucken der Bogenvorderseite und beim Bedrucken der Bogenrückseite in Bogenlaufrichtung vorn liegt.Furthermore, the feeder sheet stack 1 and the delivery sheet stack 11 are arranged in the same stacking level 10.
The sheet stack 1; 11 are each assigned to a stack transport carriage 16, which are movable on the stacking level 10.
The sheet conveyed from the feeder sheet stack 1 to the sheet guide cylinder 4 is first printed on the back of the sheet based on this machine scheme, based on the position of the sheet on the feeder sheet stack 1, and is placed on the delivery sheet stack 11 with the printed sheet back upward. This offers the possibility of bringing the delivery sheet stack 11 into the position of the feed sheet stack 1 by shifting or rotating it by 180 ° and shifting and immediately starting the subsequent printing of the front of the sheet in a second sheet pass without turning the stack. Turning the stack offers the advantage that the contact edge relevant for high-quality printing is always at the front, ie when printing on the front of the sheet and when printing on the back of the sheet in the direction of sheet travel.

In Fig. 2 ist das Handling des Anlegerbogenstapels 1 und des Auslagebogenstapels 11 beim Bedrucken der Bogenvorderseite und Bogenrückseite schematisch dargestellt.In Fig. 2 the handling of the feeder sheet stack 1 and the delivery sheet stack 11 is at Printing of the sheet front and sheet back shown schematically.

In der ersten Phase wird der Anlegerbogenstapel 1 in seine Ausgangsposition gefahren und der Stapeltransportwagen 16 des Auslagebogenstapels 11 bereitgestellt. Danach (Schema darunter) wird der Anlegerbogenstapel 1 und der Stapeltransportwagen 16 durch eine Vertikalbewegung von der Unterseite 19 des jeweiligen Stapeltransportwagens 16 zugeordneten Kragarmen 18 (Fig. 3) in seine Betriebsposition gebracht.
Nunmehr beginnt der Druckvorgang, d.h. die zu bedruckenden Bogen 12 werden vom Anlegerbogenstapel 1 entnommen, auf der Bogenrückseite bedruckt - schematisch durch ein gestricheltes Dreieck angedeutet - zum Auslagebogenstapel 11 gefördert und dort mit der bedruckten Bogenrückseite nach oben - schematisch durch ein ausgefülltes Dreieck angedeutet - abgelegt. Dieser Vorgang wird fortgesetzt bis der Anlegerbogenstapel 1 leer und in seiner oberen Position und der Auslagebogenstapel 11 voll und in einer Zwischenposition ist. In the first phase, the stack of feeder sheets 1 is moved into its starting position and the stack transport carriage 16 of the delivery sheet stack 11 is made available. Thereafter (diagram below), the stack of feeder sheets 1 and the stacking trolley 16 are brought into their operating position by a vertical movement from the underside 19 of the cantilever arms 18 (FIG. 3) associated with the respective stacking trolley 16.
Now the printing process begins, ie the sheets 12 to be printed are removed from the feeder sheet stack 1, printed on the back of the sheet - indicated schematically by a dashed triangle - conveyed to the delivery sheet stack 11 and stored there with the printed back of the sheet facing upward - indicated schematically by a filled triangle . This process continues until the feeder sheet stack 1 is empty and in its upper position and the delivery sheet stack 11 is full and in an intermediate position.

In der folgenden zweiten Phase wird eine obere Rollbahn 24 eingeschwenkt, der leere Stapeltransportwagen 16 des Anlegerbogenstapels 1 von der Kragarmen 18 auf die obere Rollbahn 24 abgesetzt und auf der oberen Rollbahn, die schräg angeordnet ist, bis in die Betriebsposition des Auslagebogenstapels gebracht. Der Auslagebogenstapel 11 wird von den Kragarmen 18 auf den Drehtisch 13 abgesenkt, um 180° gedreht und auf die Linearfördereinheit 8 abgesenkt. Danach wird der Auslagebogenstapel 11 in die Ausgangsposition des Anlegerbogenstapels 1 verfahren und danach in die Betriebsposition gebracht.
Die zweite Phase ist in Fig. 2 in der Ausführung mit einem Drehtisch 13 und einer Linearfördereinheit 8 dargestellt.
Die Unterseite der Stapeltransportwagen 16 des Anlegerbogenstapels 1 und des Auslagebogenstapels 11 ist dabei der Linearfördereinheit 8 zugeordnet.
Dem Drehtisch 13 sind die Rollen 17 der Stapeltransportwagen 16 zugeordnet.
Nunmehr beginnt in der dritten Phase wieder der Druckvorgang, d.h. die zu bedruckenden Bogen werden vom in der Position des Anlegerbogenstapels 1 befindlichen Auslagebogenstapel 11 entnommen, auf der Bogenrückseite bedruckt, zum in der Position des Auslagebogenstapels 11 befindlichen Anlegerbogenstapel 1 gefördert und dort mit der bedruckten Bogenrückseite nach oben - schematisch durch ein Dreieck angedeutet - abgelegt. Dieser Vorgang wird fortgesetzt bis der Auslagebogenstapel 11 leer und in seiner oberen Position und der Anlegerbogenstapel 1 voll und in einer Zwischenposition ist; danach wird der Stapeltransportwagen 16 des Auslagebogenstapels 11 auf die eingangs erwähnte Ausgangsposition abgesenkt.
In der folgenden vierten Phase wird sowohl der leere Stapeltransportwagen 16 des Auslagebogenstapels 11 als auch der Anlegerbogenstapel 1 mit den beidseitig bedruckten Bogen ausgefahren.
In Fig. 3 und 4 ist die Einrichtung zur Realisierung des an Hand Fig. 2 beschriebenen Ablaufes dargestellt, wobei in Fig. 3 die obere Teilfigur eine Seitenansicht mit dem leeren Stapeltransportwagen 16 des Anlegerbogenstapels 1 in der Position Anlegerbogenstapel und die untere Teilfigur eine Draufsicht mit Arbeitsstellung des Drehtisches 13 darstellt. In Fig. 4 stellt die obere Teilfigur eine Seitenansicht mit dem leeren Stapeltransportwagen 16 des Anlegerbogenstapels in der Position Auslagebogenstapel und die untere Teilfigur eine Draufsicht mit Ruhestellung des Drehtisches 13 dar.
Zur Ausführung der Vertikalbewegung der Bogenstapel 1; 11 ist im seitlichen Bereich von Anlegerbogenstapel 1 und Auslagebogenstapel 11 jeweils ein symmetrisch zur Maschinenlängsachse 20 angeordneter Kragarm 18 angeordnet. Durch die Verwendung von Kragarmen 18 für die Vertikalbewegung der Stapel 1; 11 ist eine freie Durchfahrt der Stapel 1; 11 im Anleger- und Auslagebereich der Druckmaschine gewährleistet. Die Kragarme 18 sind der Unterseite 19 der jeweiligen Stapeltransportwagen 16 zugeordnet.
In Richtung quer zur Maschinenlängsachse 20 ist beidseitig neben den Kragarmen 18 eine Linearfördereinheit 8, beispielsweise als Rollbahn ausgebildet, und neben jeder Linearfördereinheit 8 eine Laufbahn 21 für die Rollen 17 der Stapeltransportwagen 16 angeordnet.

The underside of the stack transport car 16 of the feeder sheet stack 1 and the delivery sheet stack 11 is assigned to the linear conveyor unit 8.
The rollers 17 of the stacking trolleys 16 are assigned to the rotary table 13.
Now the printing process begins again in the third phase, that is to say the sheets to be printed are removed from the delivery sheet stack 11 located in the position of the delivery sheet stack 1, printed on the back of the sheet, conveyed to the delivery sheet stack 1 located in the position of the delivery sheet stack 11 and there with the printed back of the sheet upwards - schematically indicated by a triangle - filed. This process is continued until the delivery sheet stack 11 is empty and in its upper position and the feeder sheet stack 1 is full and in an intermediate position; then the stack transport carriage 16 of the delivery sheet stack 11 is lowered to the starting position mentioned at the beginning.
In the following fourth phase, both the empty stack transport carriage 16 of the delivery sheet stack 11 and the feeder sheet stack 1 are extended with the sheets printed on both sides.
3 and 4, the device for realizing the sequence described with reference to FIG. 2 is shown, in FIG. 3 the upper part of the figure showing a side view with the empty stack transport carriage 16 of the stack of feed sheets 1 in the position of the stack of feed sheets and the lower part of the figure showing a top view Working position of the turntable 13 represents. 4, the upper part of the figure shows a side view with the empty stack transport carriage 16 of the stack of feed sheets in the delivery sheet stack position, and the lower part of the figure shows a top view with the rotary table 13 in the rest position.
To carry out the vertical movement of the sheet stack 1; 11, a cantilever arm 18, which is arranged symmetrically to the longitudinal axis 20 of the machine, is arranged in the lateral area of the feeder sheet stack 1 and the delivery sheet stack 11. By using cantilever arms 18 for the vertical movement of the stack 1; 11 is a free passage of stacks 1; 11 guaranteed in the feeder and delivery area of the printing press. The cantilever arms 18 are assigned to the underside 19 of the respective stacking trolleys 16.
In the direction transverse to the longitudinal axis 20 of the machine, a linear conveyor unit 8, for example as a roller conveyor, is arranged on both sides next to the cantilever arms 18, and a track 21 for the rollers 17 of the stacking trolleys 16 is arranged next to each linear conveyor unit 8.
Each track 21 is laterally delimited by at least one guide rail 22, the rollers 17 being assigned to the guide rail. For this purpose, the rollers are designed as combination rollers (rollers and guide rollers) equipped with lateral guide rollers.
The pivot point of the rotary table 13 is arranged on the machine longitudinal axis 20 in the region of the delivery sheet stack 11. The turntable 13 is designed as a turntable / lifting table.
The turntable 13 is equipped with four support arms 23, which correspond to the rollers 17 of the stacking trolleys 16 in the working position (FIG. 3, lower part of the figure).
In the rest position, the support arms 23 release the raceways 21 (FIG. 4, lower part of the figure). In the area above the stack 1; 11 is arranged opposite to the longitudinal axis of the machine next to each cantilever arm 18, an upper roller conveyor 24 for transporting the stack transport carriage 16 of the feeder sheet stack 1 into the operating position of the delivery sheet stack 11.
Each of the four upper runways 24 is equipped with a device for vertical movement 25. Furthermore, the upper runways can be pivoted from a horizontal position or inclined position into a vertical position, shown in broken lines in FIG. 4. The underside of the stacking trolley 16 is assigned to the upper runways 24.

Die Wirkungsweise dieser Einrichtung wird nachfolgend beschrieben.
Der leere Stapeltransportwagen 16 des Anlegerbogenstapels 1 wird von den Kragarmen 18 auf die oberen Rollbahnen 24, die vorher aus ihrer vertikalen Stellung in die geneigte Stellung eingeschwenkt wurden, abgesetzt. Dabei ist die Unterseite 19 des Stapeltransportwagens 16 der oberen Rollbahn 24 zugeordnet. The operation of this device is described below.
The empty stack transport carriage 16 of the feeder sheet stack 1 is deposited by the cantilever arms 18 onto the upper runways 24, which were previously pivoted from their vertical position into the inclined position. The underside 19 of the stacking trolley 16 is assigned to the upper runway 24.

Danach wird der leere Stapeltransportwagen 16 auf den oberen Rollbahnen 24 in den Bereich des Auslagebogenstapels 11 verbracht. In diesem Bereich wird der leere Stapeltransportwagen 16 von den Kragarmen 18 des Auslagebogenstapels 11 übernommen und in die Betriebsstellung gebracht.
Nach der Übergabe des leeren Stapeltransportwagens 16 des Anlegerbogenstapels 1 an die obere Rollbahn 24 werden die Kragarme 18 auf die Ausgangsstellung abgesenkt.
Der Stapeltransportwagen 16 des Auslagebogenstapels 11 wird mit seinen Rollen 17 durch eine Vertikalbewegung der Kragarme 18 auf den sich in Arbeits- und Hubstellung befindlichen Drehtisch 13 (Fig. 3 untere Teilfigur) abgesetzt und um 180° gedreht. Durch eine Vertikalbewegung des Drehtisches 13 wird nunmehr die Unterseite 19 des Stapeltransportwagens 16 des gedrehten Auslagebogenstapels auf die Linearfördereinheit 8 abgesetzt und nach einer Drehbewegung des Drehtisches in seine Ruheposition (Fig. 4 untere Teilfigur) in die Position des Anlegerbogenstapels 1 verbracht. Der Stapelwechsel ist damit beendet. Thereafter, the empty stacking trolley 16 is brought onto the upper runways 24 into the area of the delivery sheet stack 11. In this area, the empty stack transport carriage 16 is taken over by the cantilever arms 18 of the delivery sheet stack 11 and brought into the operating position.
After the empty stack transport carriage 16 of the feeder sheet stack 1 has been transferred to the upper runway 24, the cantilever arms 18 are lowered to the starting position.
The stack transport carriage 16 of the delivery sheet stack 11 is placed with its rollers 17 by a vertical movement of the cantilever arms 18 onto the turntable 13 which is in the working and lifting position (lower part of FIG. 3) and rotated through 180 °. By a vertical movement of the turntable 13, the underside 19 of the stack transport carriage 16 of the rotated delivery sheet stack is now placed on the linear conveyor unit 8 and after a rotary movement of the turntable into its rest position (lower part of FIG. 4) it is brought into the position of the feeder sheet stack 1. The stack change is now complete.
