Description

Die Erfindung betrifft eine Einrichtung zum seitlichen Ausrichten von Bogen in einer Bogendruckmaschine auf einer rotierenden Trommel mit einem Greifersystem, das durch mindestens ein motorisches Stellglied in axialer Richtung verschiebbar vorgesehen ist.The invention relates to a device for the lateral alignment of sheets in a sheet-fed press on a rotating drum with a gripper system which is slidably provided by at least one motor actuator in the axial direction.

Aus der EP 753 407 B1 ist eine derartige Vorrichtung zum seitlichen Ausrichten von Bogen auf einer Trommel bekannt. Bei dieser Vorrichtung werden die Ist-Lage einer Seitenkante des auszurichtenden Bogens durch Messelemente erfasst und durch einen Soll-Ist-Vergleich Impulse generiert, die einem motorischen Stellglied zugeführt werden. Das motorische Stellglied ist gestellfest im Kanal der Trommel angeordnet und greift an dem axial verschiebbar in der Trommel gelagerten Greifersystem an. Durch axiales Verschieben des Greifersystems wird die Soll-Lage des auszurichtenden Bogens realisiert.From EP 753 407 B1 such a device for the lateral alignment of sheets on a drum is known. In this device, the actual position of a side edge of the sheet to be aligned are detected by measuring elements and generated by a target-actual comparison pulses that are supplied to a motor actuator. The motor actuator is fixed to the frame in the channel of the drum and engages the axially displaceable mounted in the drum gripper system. By axial displacement of the gripper system, the desired position of the sheet to be aligned is realized.

Nachteilig ist, dass einerseits für eine gute Bogenführung ein enger Kontakt zwischen dem Bogen und dem axial fixierten Trommelmantel erforderlich ist, andererseits jedoch das Greifersystem axial verschoben wird. Das führt dazu, dass die hinteren Bogenteile der durch das Greifersystem eingeleiteten Ausrichtbewegung nicht folgen können, was zu einer Faltenbildung und damit zu einem Makulaturanfall führt.The disadvantage is that on the one hand for a good bowing close contact between the sheet and the axially fixed drum shell is required, on the other hand, however, the gripper system is axially displaced. The result is that the rear parts of the sheet can not follow the introduced by the gripper alignment movement, resulting in wrinkling and thus a waste of waste.

Aus der DE 20 46 602 A1 ist es bekannt, mit Messmitteln die Abweichung der Seitenkante des auszurichtenden Bogens von der Soll-Lage zu erfassen und die gesamte Trommel mit dem im Greifersystem gehaltenen Bogen sowie dem Trommelmantel axial so zu verschieben, dass die seitliche Soll-Lage des auszurichtenden Bogens realisiert wird.From DE 20 46 602 A1 it is known to detect with measuring means the deviation of the side edge of the sheet to be aligned from the desired position and to move the entire drum with the held in the gripper system sheet and the drum shell axially so that the lateral setpoint Location of the sheet to be aligned is realized.

Nachteilig sind die große Trommelmasse und der hohe technische Aufwand der Trommellagerung.Disadvantages are the large drum mass and the high technical complexity of drum storage.

Aufgabe der Erfindung ist die Schaffung einer gattungsgemäßen Einrichtung, die mit einfachen Mitteln zu realisieren ist und eine qualitätsgerechte Zuführung der Bogen ermöglicht.The object of the invention is to provide a generic device that can be realized with simple means and allows a quality-compliant feeding the sheet.

Erfindungsgemäß wird die Aufgabe durch eine Einrichtung nach den Merkmalen des Anspruchs 1 gelöst.According to the invention the object is achieved by a device according to the features of claim 1.

Durch die erfindungsgemäße Lösung ist es möglich, mit einfachen Mitteln eine Einrichtung zu schaffen, die es ermöglicht, unterschiedliche Materialien ohne Makulaturanfall zu verarbeiten.The solution according to the invention makes it possible to create a device with simple means which makes it possible to process different materials without waste of waste.

The invention will be explained in more detail in an embodiment. In the accompanying drawings show

Die Fig. 1 zeigt eine Bogenanlage, bestehend aus einem Anlegtisch 1 mit Vordermarken 2, einer Schwinganlage 3 und einer Trommel 4. Der Trommel 4 ist ein Druckzylinder 5 nachgeordnet. Die Schwinganlage 3 besteht aus einem Schwinger 6 sowie einem diesem zugeordneten Schwingergreifersystem 7, das Greifer 8 und Greiferauflagen 9 aufweist.
In einem Trommelkanal 10 der Trommel 4 ist ein Greifersystem 11 in axialer Richtung verschiebbar gelagert. Das Greifersystem 11 besteht aus auf einer Greiferwelle 12 geklemmten Greiferfingern 13, die mit Greiferaufschlägen 14 korrespondieren. Das Greifersystem 11 ist als funktionelle Einheit in einem Schlitten 15 eingeordnet, der verschiebbar im Trommelkanal 10 gelagert ist. Am Schlitten 15 greift ein Mitnehmer 16 an, der mit einer konzentrisch in einem Trommelgrundkörper 29 angeordneten Ziehwelle 17 verbunden ist (Fig. 2). Die Ziehwelle 17 ist in Lagern 18 geführt. Am äußeren Ende der Ziehwelle 17 ist mit dieser drehfest verbunden eine Gewindemutter 19 vorgesehen, in welche eine Gewindespindel 20 eingreift. Die Gewindespindel 20 ist gegen axiales Verschieben durch ein Axiallager 21 in einem Motorflansch 22 gelagert. Der Motorflansch 22 ist gestellfest an einer Seitenwand 23 angeordnet, in der die Trommel 4 mittels eines Wälzlagers 24 und einer Buchse 25 gelagert ist. Mit dem Motorflansch 22 ist ein Motor 26 fest verbunden. Eine Motorwelle 27 des Motors 26 ist durch eine drehsteife Kupplung 28 mit der Gewindespindel 20 gekoppelt.Fig. 1 shows a sheet system consisting of a feed table 1 with front marks 2, a vibration system 3 and a drum 4. The drum 4 is a pressure cylinder 5 downstream. The oscillating system 3 consists of a vibrator 6 and a vibrating gripper system 7 associated therewith, which has grippers 8 and gripper pads 9.
In a drum channel 10 of the drum 4, a gripper system 11 is slidably mounted in the axial direction. The gripper system 11 consists of clamped on a gripper shaft 12 gripper fingers 13, which correspond to gripper clutches 14. The gripper system 11 is classified as a functional unit in a carriage 15 which is slidably mounted in the drum channel 10. On the carriage 15 engages a driver 16, which is connected to a concentrically arranged in a drum base 29 pulling shaft 17 (Fig. 2). The pulling shaft 17 is guided in bearings 18. At the outer end of the pull shaft 17 is rotatably connected to a threaded nut 19 is provided, in which a threaded spindle 20 engages. The threaded spindle 20 is mounted against axial displacement by a thrust bearing 21 in a motor flange 22. The motor flange 22 is fixed to the frame on a side wall 23, in which the drum 4 is mounted by means of a rolling bearing 24 and a bush 25. With the motor flange 22, a motor 26 is fixedly connected. A motor shaft 27 of the motor 26 is coupled by a torsionally stiff coupling 28 with the threaded spindle 20.

Mit dem Trommelgrundkörper 29 sind zwei Trommelwangen 30, in Figur 2 ist nur eine der Trommelwangen 30 dargestellt, drehfest verbunden. Von den Trommelwangen 30 wird ein Trommelmantel 31 geführt, der aus einem in Drehrichtung 34 dem Greifersystem 11 vorgeordneten Segment 32 und einem dem Greifersystem 11 nachgeordneten Segment 33 besteht.
Das vorgeordnete Segment 32 ist starr mit den Trommelwangen 30 verbunden, während das nachgeordnete Segment 33 in axialer Richtung verschiebbar den Trommelwangen 30 zugeordnet ist. Dazu sind mit den Trommelwangen 30 Führungsbolzen 35 fest verbunden, auf deren freien Ende über Gleitbuchsen 36 das nachgeordnete Segment 33 gelagert ist. Das nachgeordnete Segment 33 ist über ein Koppelglied 37 mit dem Schlitten 15 verbunden, so dass das nachgeordnete Segment 33 axialen Bewegungen des Schlittens 15 synchron folgen kann.
Das nachgeordnete Segment 33 erstreckt sich über einen Erstreckungswinkel β, der etwa einem Segmentwinkel α entspricht, wobei der Segmentwinkel α eingeschlossen wird von einer Geraden g1, die die Mittelpunkte des Druckzylinders 5 sowie der Trommel 4 verbindet und einer Geraden g2, auf der der Mittelpunkt der Trommel 4 und der Gestellpunkt des Schwingers 6 liegen.
In an sich bekannter Weise werden Bogen 38 in einem Bogenanleger vereinzelt und über einen Bändertisch auf dem Anlegtisch 1 sowie mit der Vorderkante gegen die am Anlegtisch 1 positionierten Vordermarken 2 gefördert und so nach der Vorderkante ausgerichtet. Durch Messmittel wird die Ist-Lage der Seitenkante erfasst und ein Messwert generiert, der einer Auswerteinheit zu einem Soll-Ist-Vergleich zugeführt wird. Weicht der Ist-Wert von einem vorgegebenen Soll-Wert ab, wird von der Auswerteinheit ein Stellsignal erzeugt, mit dem der Motor 26 angesteuert wird.
Der Motor 26 läuft mit einer Drehzahl um, die synchron der Drehzahl der Trommel 4 folgt. Die Drehzahlsynchronisation des Motors 26 mit der Trommel 4 wird durch einen maschineninternen oder einen separaten, nicht dargestellten Drehzahlgeber realisiert. Dabei wird ständig die Momentandrehzahl der Maschine oder der Trommel 4 erfasst und durch diesen Messwert des Motors 26 nachgeführt, so dass die Motorwelle 27 und die Ziehwelle 17 synchron umlaufen.
Der auf dem Anlegtisch 1 nach der Vorderkante 4 ausgerichtete Bogen 38, dessen Seitenkante von dem Messmittel erfasst wurde, wird zwischen den Greifern 8 und den Greiferauflagen 9 des Schwingers 6 geklemmt, vom Anlegtisch 1 abgezogen und zur Trommel 4 transportiert, wobei die Vordermarken 2 in eine Position unter dem Anlegtisch 1 geführt werden. Der abziehende Bogen 39 wird vom Schwinger 6 zur Trommel 4 transportiert und vom Schwingergreifersystem 7 an das Greifersystem 11 der Trommel 4 übergeben, wobei die Trommel 4 in Drehrichtung 34 dreht und den abziehenden Bogen 39 zum Druckzylinder 5 transportiert. Dabei schmiegt sich der abziehende Bogen 39 an das dem Greifersystem 11 nachgeordnete Segment 33 des Trommelmantels 31 an.
Wurde durch Messmittel auf dem Anlegtisch 1 erfasst, dass die Seitenkante des abziehenden Bogens 39 von der Soll-Lage abweicht, wird die Ist-Lage der Soll-Lage auf der Trommel 4 während des Transports zum Druckzylinder 5 angepasst, indem das Greifersystem 11 axial verschoben wird. Dazu wird durch das dem Motor 26 zugeführte, aus dem Soll-Ist-Vergleich generierte Stellsignal die Momentandrehzahl des Motors 26 vor- oder nacheilend verstellt und danach wieder synchronisiert. Durch die vor- oder nacheilende Verstellung der Drehzahl des Motors 26 wird eine Verdrehung zwischen Gewindemutter 19 und Gewindespindel 20 initiiert und damit die Ziehwelle 17 in oder entgegen einer Pfeilrichtung 40 verschoben. Da die Ziehwelle 17 über den Mitnehmer 16 mit dem das Greifersystem 11 tragenden Schlitten 15 in Wirkverbindung steht, folgt dieses der Stellbewegung der Ziehwelle 17, so dass der vom Greifersystem 11 geklemmte abziehende Bogen 39 axial verschoben und damit bezüglich seiner Seitenkante in die Soll-Lage verbracht wird. Da mit dem Schlitten 15 über das Koppelglied 37 das axial verschiebbar gelagerte, den abziehenden Bogen 39 führende nachgeordnete Segment 33 verbunden ist, folgt das nachgeordnete Segment 33 synchron der axialen Bewegung des Greifersystems 11, so dass der abziehende Bogen 39 problemlos auf der Trommel 4 in axialer Richtung verschoben werden kann. Der in der Soll-Lage befindliche abziehende Bogen 39 wird an den Druckzylinder 5 übergeben.
Nach der Übergabe des abziehenden Bogens 39 an den Druckzylinder 5 wird die Momentandrehzahl des Motors 26 nach- oder voreilend verstellt und damit das Greifersystem 11 mit dem nachgeordneten Segment in die Ausgangsposition zurückgeführt. Beide Stellhandlungen, also das Verschieben des Greifersystems 11 mit dem nachgeordneten Segment 33 aus einer Ausgangslage in eine die Soll-Lage des abziehenden Bogens 39 realisierende Position und das Zurückführen des Greifersystems 11 mit dem nachgeordneten Segment 33 in seine Ausgangsposition wird innerhalb einer Umdrehung der Trommel 4 realisiert.With the drum base body 29 are two drum cheeks 30, in Figure 2, only one of the drum cheeks 30 is shown, rotatably connected. Of the drum cheeks 30, a drum shell 31 is guided, which consists of a direction of rotation 34 upstream of the gripper system 11 segment 32 and a gripper system 11 downstream segment 33.
The upstream segment 32 is rigidly connected to the drum cheeks 30, while the downstream segment 33 is associated with the drum cheeks 30 in an axially displaceable manner. For this purpose, 30 guide pins 35 are fixedly connected to the drum cheeks, on the free end of sliding bushes 36, the downstream segment 33 is mounted. The downstream segment 33 is connected via a coupling member 37 with the carriage 15, so that the downstream segment 33 can follow axial movements of the carriage 15 synchronously.
The subordinate segment 33 extends over an extension angle β, which corresponds approximately to a segment angle α, wherein the segment angle α is enclosed by a straight line g 1 , which connects the centers of the impression cylinder 5 and the drum 4 and a straight line g 2 , on which Center of the drum 4 and the frame point of the vibrator 6 are.
In a conventional manner, sheets 38 are singulated in a sheet feeder and conveyed via a belt table on the feed table 1 and with the front edge against the front table 2 positioned on the feed table 1 and aligned so after the leading edge. By measuring means, the actual position of the side edge is detected and generates a measured value, which is supplied to an evaluation unit for a target-actual comparison. If the actual value deviates from a predetermined desired value, the evaluation unit generates an actuating signal with which the motor 26 is activated.
The motor 26 rotates at a speed that follows the rotational speed of the drum 4 synchronously. The speed synchronization of the motor 26 with the drum 4 is realized by a machine-internal or a separate, not shown, speed sensor. In this case, the instantaneous speed of the machine or the drum 4 is constantly detected and tracked by this measured value of the motor 26, so that the motor shaft 27 and the pull shaft 17 rotate synchronously.
The aligned on the feed table 1 after the leading edge 4 sheet 38, the side edge was detected by the measuring means is clamped between the grippers 8 and the gripper pads 9 of the vibrator 6, subtracted from the feed table 1 and transported to the drum 4, the front marks 2 in a position under the feed table 1 are performed. The withdrawing sheet 39 is transported by the oscillator 6 to the drum 4 and transferred from the vibratory gripper system 7 to the gripper system 11 of the drum 4, the drum 4 rotates in the direction of rotation 34 and the withdrawing sheet 39 is transported to the printing cylinder 5. In this case, the withdrawing sheet 39 hugs against the gripper system 11 downstream segment 33 of the drum shell 31.
Has been detected by measuring means on the feed table 1 that the side edge of the withdrawing sheet 39 deviates from the desired position, the actual position of the target position on the drum 4 during transport to the impression cylinder 5 is adjusted by the gripper system 11 axially displaced becomes. For this purpose, by the motor 26 supplied, generated from the target-actual comparison control signal, the instantaneous speed of the motor 26 before or after adjusted and then synchronized again. By the leading or lagging adjustment of the rotational speed of the motor 26, a rotation between the threaded nut 19 and threaded spindle 20 is initiated and thus the pulling shaft 17 is displaced in or against an arrow direction 40. Since the pulling shaft 17 is operatively connected to the carriage 15 carrying the gripper system 11 via the driver 16, this follows the adjusting movement of the pulling shaft 17, so that the clamping system 39 clamped by the gripper system 11 axially displaced and thus with respect to its side edge in the desired position is spent. Since with the carriage 15 via the coupling member 37, the axially displaceably mounted, the drawing sheet 39 leading downstream segment 33 is connected, the downstream segment 33 follows synchronously the axial movement of the gripper system 11, so that the withdrawing sheet 39 easily on the drum 4 in axial direction can be moved. The withdrawal sheet 39 located in the desired position is transferred to the impression cylinder 5.
After the transfer of the withdrawing sheet 39 to the pressure cylinder 5, the instantaneous speed of the motor 26 is moved later or advanced and thus the gripper system 11 is returned to the downstream segment in the starting position. Both Stellhandlungen, ie the movement of the gripper system 11 with the downstream segment 33 from a starting position in a target position of the withdrawing sheet 39 realizing position and returning the gripper system 11 with the downstream segment 33 to its initial position is within a revolution of the drum 4th realized.

Statt das motorische Stellglied als gestellfest außerhalb der Trommel 4 angeordneten Motor 26 auszubilden, kann das motorische Stellglied auch gestellfest innerhalb der Trommel 4 angeordnet werden und über ein Stellelement, das am Schlitten 15 angreift, dieses und damit das Greifersystem 11 verschoben werden.Instead of forming the motor actuator as a frame fixed outside the drum 4 arranged motor 26, the motor actuator can also be fixed to the frame within the drum 4 and an actuator that engages the carriage 15, this and thus the gripper system 11 are moved.

Es ist auch möglich, dem das Greifersystem 11 tragenden Schlitten 15 ein erstes motorisches Stellglied und dem nachgeordneten Segment 33, welches nicht über das Koppelglied 37 mit dem Schlitten 15 gekoppelt ist, ein zweites motorisches Stellglied, das ebenfalls gestellfest in der Trommel 4 angeordnet ist, zuzuordnen. Das zweite motorische Stellglied wird dann so angesteuert, dass das nachgeordnete Segment 33 synchron der axialen Bewegung des Greifersystems 11 folgt.It is also possible, the carriage 15 carrying the gripper system 11, a first motor actuator and the downstream segment 33, which is not coupled via the coupling member 37 with the carriage 15, a second motor actuator, which is also arranged fixed to the frame in the drum 4, assigned. The second motor actuator is then controlled so that the downstream segment 33 synchronously follows the axial movement of the gripper system 11.
