Mittels verschiedener Positioniermittel kann ein auf einer Schiebebühne gelagerte Papierrolle zunächst in einer Grobeinstellage und danach in eine Feineinstellage gebracht werden. Bei dieser Anlage sind Einstellsäulen entlang von Führungsschienen horizontal verfahrbar, um eine exakte Ausrichtung der Papierrolle vor deren übergabe zu gewährleisten.EP-A-0 391 061 relates to a system for loading the paper roll carrier of a rotary printing press with a paper roll. Using various positioning means, a paper roll mounted on a transfer table can first be brought into a rough setting position and then into a fine setting position. In this system, adjustment columns can be moved horizontally along guide rails in order to ensure exact alignment of the paper roll before it is transferred.

In einer Druckmaschine kann ein Druckwerk auch über einer jeweiligen individuellen Abwickeleinrichtung angeordnet sein. Eine in die Abwickeleinrichtung aufgenommene Rolle mit Bahnmaterial wird beim Abwickeln nach oben in das Druckwerk geführt. Je nach Anordnung der Druckwerke in der Druckmaschine ist möglicherweise nicht genügend Platz neben der Abwickeleinrichtung zum Einlegen und Abnehmen der Rolle (DE-C-310 813 oder GB-A-1 214 641).A printing unit can also be arranged in a printing press above a respective individual unwinding device. A roll included in the unwinder Web material is fed upwards into the printing unit during unwinding. Depending on the arrangement of the printing units in the printing press, there may not be enough space next to the unwinding device for inserting and removing the roll (DE-C-310 813 or GB-A-1 214 641).

Der Erfindung liegt die Aufgabe zugrunde, an einer Abwickeleinrichtung für eine Druckmaschine, die Handhabung des Bahnvorrats zu verbessern.The invention has for its object to improve the handling of the web supply on an unwinding device for a printing press.

Die Aufgabe wird gemäß der Merkmale des Patentanspruches 1 gelöst.The object is achieved according to the features of patent claim 1.

Eine nach vorliegender Erfindung konstruierte Abwickeleinrichtung ermöglicht es, die Rolle von der Vorder-/Bedienerseite einzulegen. Die Rolle mit Bahnmaterial wird außerhalb des Rahmens auf den Träger geladen und mit dem Träger in den Rahmen bewegt. In der bevorzugten Ausgestaltung der Erfindung stützen die Führungsschienen an dem Rahmen den Träger in einer Position, in welcher die Rolle koaxial auf die an dem Rahmen angebrachte Rollenbremse ausgerichtet ist. In einer Druckmaschine können eine Vielzahl austauschbarer Träger verwendet werden, wobei die Führungsschienen in jeder Abwickeleinrichtung dafür sorgen, daß jeder Träger in einer Position gestützt wird, worin die zugeordnete Rolle sich koaxial mit der zugeordneten Bremse befindet.An unwinding device constructed according to the present invention makes it possible to insert the roll from the front / operator side. The roll of web material is loaded onto the carrier outside the frame and moved into the frame with the carrier. In the preferred embodiment of the invention, the guide rails on the frame support the carrier in a position in which the roller is coaxially aligned with the roller brake attached to the frame. A variety of interchangeable brackets can be used in a printing machine, with the guide rails in each unwinder ensuring that each bracket is supported in a position where the associated roller is coaxial with the associated brake.

Anhand der beigefügten, nachstehend erläuterten Zeichnungen wird eine bevorzugte Ausführungsform der Erfindung im folgenden näher beschrieben.

Fig. 1
is a schematic front view of a part of a printing unit constructed according to the present invention;
Fig. 2
is a view taken along line 2-2 of FIG. 1, with no parts, for clarity of illustration.

Wie in Fig. 1 gezeigt, umfaßt ein nach vorliegender Erfindung konstruierter Druckmaschinenteil 10 eine Abwickeleinrichtung 12 und ein Druckwerk 14. Die Abwickeleinrichtung 12 umfaßt einen Rahmen 16 und einen Träger 18. Der Träger 18 ist in den Rahmen 16 hinein und aus dem Rahmen 16 heraus bewegbar, und das Druckwerk 14 ist über dem Rahmen 16 angeordnet. Das Druckwerk 14 umfaßt ein Paar Druckwalzen 20 zum Bedrucken einer Materialbahn 22, welche von der Abwickeleinrichtung 12 durch das Druckwerk 14 bewegt wird.As shown in FIG. 1, a printing machine part 10 constructed according to the present invention comprises an unwinder 12 and a printing unit 14. The unwinder 12 comprises a frame 16 and a carrier 18. The carrier 18 is in and out of the frame 16 movable, and the printing unit 14 is arranged over the frame 16. The printing unit 14 comprises a pair of printing rollers 20 for printing on a material web 22 which is moved by the unwinder 12 through the printing unit 14.

Wie in den Fig. 1 und 2 gezeigt, hat der Rahmen 16 generell eine rechteckige Struktur. Ein Paar voneinander beabstandete Rahmenteile 24 und 26 bestimmen die Vorder-/Bedienerseite des Rahmens 16. Ein einzelnes Rahmenteil 28 bestimmt die Hinter-/Getriebeseite des Rahmens 16. Mehrere Traversen 30 befestigen die Rahmenteile 24 und 26 an dem Rahmenteil 28. Die Rahmenteile 24 und 26 haben jeweilige Randflächen 32 und 34, die über der Vorder-/Bedienerseite des Rahmens 16 einander gegenüberliegen. Die Randflächen 32 und 34 bestimmen so eine öffnung, durch welche der Träger 18 bewegbar ist.As shown in FIGS. 1 and 2, the frame 16 generally has a rectangular structure. A pair of spaced frame members 24 and 26 define the front / operator side of the frame 16. A single frame member 28 defines the rear / transmission side of the frame 16. A plurality of cross members 30 attach the frame members 24 and 26 to the frame member 28. The frame members 24 and 26 have respective edge surfaces 32 and 34 which are opposite each other over the front / operator side of the frame 16. The edge surfaces 32 and 34 thus define an opening through which the carrier 18 can be moved.

Es sind ein Paar Klammern 36 an den Rahmenteilen 24 und 26 an der Vorder-/Bedienerseite des Rahmens 16 angebracht. Diese Klammern 36 erstrecken sich innerhalb der öffnung zwischen den Randflächen 32 und 34. Ein Paar Führungsschienen 38 sind mit ihrem vorderen Ende an den Klammern 36 und mit ihrem hinteren Ende an dem Rahmenteil 28 befestigt. Die Führungsschienen 38 liegen parallel zueinander und befinden sich zwischen den Randflächen 32 und 34, welche die öffnung an der Vorder-/Bedienerseite des Rahmens 16 bestimmen.A pair of clips 36 are attached to frame members 24 and 26 on the front / operator side of frame 16. These brackets 36 extend within the opening between the edge surfaces 32 and 34. A pair of guide rails 38 are attached with their front end to the brackets 36 and with their rear end to the frame part 28. The guide rails 38 are parallel to one another and are located between the edge surfaces 32 and 34, which determine the opening on the front / operator side of the frame 16.

Eine Anzahl von Bahnleitwalzen sind quer über die Innenseite des Rahmens 16 angebracht, nämlich eine obere Leitwalze 40, eine untere Leitwalze 42 und eine Ausglelchswalze 44. Ein Ausgleichsmechanismus 46 von bekannter Ausführung ist der Auslgeichswalze 44 zugeordnet. Der Ausgleichsmechanismus 46 bewirkt eine begrenzte Drehbewegung der Ausgleichswalze 44 um eine Nabe 48 in bekannter Weise. Eine Bremse 50 ist an dem Rahmenteil 28 neben einer Bremsöffnung 52 an der Hinter-/Getriebeseite des Rahmens 16 angebracht. Die Bremse 50 ist funktionsmäßig mit dem Ausgleichsmechanismus 46 in bekannter Weise verbunden.A number of web guide rolls are mounted across the inside of the frame 16, namely an upper guide roll 40, a lower guide roll 42 and a compensating roll 44. A compensating mechanism 46 of known design is associated with the compensating roll 44. The compensating mechanism 46 effects a limited rotational movement of the compensating roller 44 around a hub 48 in a known manner. A brake 50 is attached to the frame part 28 next to a brake opening 52 on the rear / transmission side of the frame 16. The brake 50 is functionally connected to the compensating mechanism 46 in a known manner.

Wie in den Fig. 1 und 2 gezeigt, hält der Träger 18 eine Rolle 60 mit Bahnmaterial 22. Die Rolle 60 hat einen Rollenkern 62. Der Träger 18 umfaßt ein Paar voneinander beabstandete Trägerrahmenteile 64 und 66. Jedes der Trägerrahmenteile 64 und 66 umfaßt ein Paar Rollenlager 68, in welchen ein Endteil des Rollenkerns 62 drehbar gelagert ist. Eine Rollenkernsperre 70 ist in dem Trägerrahmenteil 64 drehbar gelagert. Die Rollenkernsperre 70 ist in eine und aus einer Kontaktposition mit dem Rollenkern 62 bewegbar, um den Rollenkern 62 gegen eine axiale Bewegung auf dem Träger 18 zu sichern. Ein Seitenanschlagmechanismus 72 ist ebenfalls an dem Trägerrahmenteil 64 angebracht. Der Seitenanschlagmechanismus 72 bewirkt das Regulieren der axialen Position des Rollenkerns 62 auf dem Träger 18. Die Rollenkernsperre 70 und der Seitenanschlagmechanismus 72 sind von bekannter Ausführung und kooperieren miteinander und mit dem Rollenkern 62 in bekannter Weise. Die Trägerrahmenteile 64 und 66 tragen ebenfalls eine Leitwalze 74, die sich quer zum Träger 18 erstreckt.1 and 2, the carrier 18 holds a roll 60 of web material 22. The roll 60 has a roll core 62. The carrier 18 includes a pair of spaced-apart support frame members 64 and 66. Each of the support frame members 64 and 66 includes one A pair of roller bearings 68 in which an end part of the roller core 62 is rotatably supported. A roller core lock 70 is rotatably supported in the support frame part 64. The roller core lock 70 can be moved into and out of a contact position with the roller core 62 in order to secure the roller core 62 against axial movement on the carrier 18. A side stop mechanism 72 is also attached to the support frame member 64. The side stop mechanism 72 regulates the axial position of the roller core 62 on the carrier 18. The roller core lock 70 and the side stop mechanism 72 are of a known design and cooperate with one another and with the roller core 62 in a known manner. The carrier frame parts 64 and 66 also carry a guide roller 74 which extends transversely to the carrier 18.

Der Träger 18 umfaßt ferner Hebeöffnungen 80 und Lagerungsflächen 82 und 84. Die Lagerungsflächen 82 an der linken Seite des Trägers 18, wie in Fig. 1 gezeigt, werden von den horizontalen unteren Randflächen der Trägerrahmenteile 64 und 66 bestimmt. Die Lagerungsflächen 84 an der rechten Seite des Trägers 18 werden von den winkeligen unteren Randflächen der Platten 86 bestimmt, welche an den Trägerrahmenteilen 64 und 66 befestigt sind. Wenn sich der Träger 18 in der Arbeitsposition befindet, wie in den Fig. 1 und 2 gezeigt, so ruhen die Lagerungsflächen 82 und 84 auf den Führungsschienen 38, und der Rollenkern 62 liegt koaxial mit der Bremsöffnung 52 in dem Rahmenteil 28.Carrier 18 also includes lift openings 80 and bearing surfaces 82 and 84. The bearing surfaces 82 on the left side of carrier 18, as shown in FIG. 1, are from the horizontal lower peripheral surfaces of the Carrier frame parts 64 and 66 determined. The bearing surfaces 84 on the right side of the carrier 18 are determined by the angled lower edge surfaces of the plates 86, which are fastened to the carrier frame parts 64 and 66. When the carrier 18 is in the working position, as shown in FIGS. 1 and 2, the bearing surfaces 82 and 84 rest on the guide rails 38, and the roller core 62 lies coaxially with the brake opening 52 in the frame part 28.

Beim Betrieb der Druckmaschine 10 wird der Träger 18 in die und aus der Arbeitsposition bewegt, wie in Fig. 1 gezeigt. Die Rolle 60 mit Bahnmaterial 22 wird zunächst außerhalb des Rahmens 16 auf den Träger 18 geladen, indem der Rollenkern 62 mittels der Rollenkernsperre 70 auf die Rollenlager 68 geklemmt wird. Das vordere Endteil 90 des Bahnmaterials 22 wird dann um die Leitwalze 74 gewunden und auf der rechte Seite der Rolle 60 angeklebt, wie in Fig. 1 gezeigt. Das vordere Endteil 90 des Bahnmaterials 22 befindet sich somit in einer zugänglichen Position.During operation of the printing press 10, the carrier 18 is moved into and out of the working position, as shown in FIG. 1. The roll 60 with web material 22 is first loaded onto the carrier 18 outside the frame 16 by the roll core 62 being clamped onto the roll bearings 68 by means of the roll core lock 70. The front end portion 90 of the web material 22 is then wound around the guide roller 74 and glued to the right side of the roller 60, as shown in FIG. 1. The front end portion 90 of the web material 22 is thus in an accessible position.

Nachdem die Rolle 60 auf den Träger 18 geladen worden ist, wird der Träger 18 von den Gabelarmen 92 eines Gabelstaplers 96 oder ähnlichem durch die öffnung an der Vorderseite des Rahmens 16 bewegt und auf die Führungsschienen 38 niedergelassen. Die Rolle 60 wird somit parallel zu ihrer Achse und parallel zu den Achsen der Druckwalzen 20 in den Rahmen 16 des Druckwerks 14 bewegt. Da der Rollenkern 62 sich koaxial mit der Bremsöffnung 52 erstreckt wenn der Träger 18 auf den Führungsschienen 38 ruht, kann dann der Seitenanschlagmechanismus 72 nach Bedarf betätigt werden, um den Rollenkern 62 durch die Bremsöffnung 52 hindurch in den Kontakt mit der Bremse 50 zu bewegen. Entsprechend diesem Merkmal der Erfindung werden die Platten 86 auf den Trägerrahmenteilen 64 und 66 in Positionen angebracht, in welchen die koaxiale Ausrichtung des Rollenkerns 62 und der Bremsöffnung 52 gewährleistet ist, wenn der Träger 18 auf den Führungsschienen 38 ruht. Eine Vielzahl von Trägern gleicher Konstruktion wie der Träger 18 sind deshalb in dem Rahmen 16 und anderen gleichförmigen Rahmen auswechselbar.After the roller 60 has been loaded onto the carrier 18, the carrier 18 is moved by the fork arms 92 of a forklift 96 or the like through the opening in the front of the frame 16 and lowered onto the guide rails 38. The roller 60 is thus moved parallel to its axis and parallel to the axes of the printing rollers 20 in the frame 16 of the printing unit 14. Since the roller core 62 extends coaxially with the brake opening 52 when the carrier 18 rests on the guide rails 38, the side stop mechanism 72 can then be actuated as required to move the roller core 62 through the brake opening 52 into contact with the brake 50. According to this feature of the invention, the plates 86 are mounted on the support frame parts 64 and 66 in positions in which the coaxial alignment of the roller core 62 and the brake opening 52 is ensured, when the carrier 18 rests on the guide rails 38. A plurality of supports of the same construction as the support 18 are therefore interchangeable in the frame 16 and other uniform frames.

Nachdem der Träger 18 in dem Rahmen 16 in Arbeitsposition bewegt worden ist, kann das vordere Endteil 90 des Bahnmaterials 22 entlang der gezeigten Strecke zwischen den Druckzylindern 20 in dem Druckwerk 14 oder alternativ entlang einer Strecke, die rechts unten aus dem Rahmen 16 in ein anderes Druckwerk (nicht gezeigt) verläuft, eingefädelt werden. Während das Bahnmaterial 22 von den Druckwalzen 20 in Längsrichtung durch das Druckwerk 14 bewegt wird, wird es von der Rolle 60 abgewickelt. Die Spannung in dem Bahnmaterial 22 zwischen der Rolle 60 und dem Druckwerk 14 wird gesteuert von der Ausgleichswalze 44, welche eine direkte Wirkung auf die Bahn 22 hat, und von der Bremse 50, welche eine direkte Wirkung auf den Rollenkern 62 hat. Wenn die Rolle 60 mit dem Bahnmaterial 22 verbraucht ist, kann der Träger 18 entfernt und eine andere Rolle 60 eingelegt werden oder der Träger 18 gegen eine anderen Träger, der eine andere Rolle enthält, ausgewechselt werden.After the carrier 18 has been moved into the working position in the frame 16, the front end part 90 of the web material 22 can be moved along the distance shown between the printing cylinders 20 in the printing unit 14 or alternatively along a distance that bottom right out of the frame 16 into another Printing unit (not shown) runs, are threaded. While the web material 22 is moved by the printing rollers 20 in the longitudinal direction through the printing unit 14, it is unwound from the roll 60. The tension in the web material 22 between the roll 60 and the printing unit 14 is controlled by the compensating roller 44, which has a direct effect on the web 22, and by the brake 50, which has a direct effect on the roll core 62. When roll 60 of web material 22 is used up, carrier 18 can be removed and another roll 60 inserted, or carrier 18 can be replaced with another carrier containing another roll.
