Description
Die Erfindung betrifft eine Druckmaschine mit schwingendem Druckzylinder und einer Bänderführung für den Bogen sowohl während des Druckes als bei der darauffolgenden Abgabe an die Ausführorgane. Bei einer Maschine dieser Art halten, die Führungsbänder, welche mit einem Ende am Zylinder befestigt sind, den Bogen während des Abrollens dadurch bis zu den Anlege- bzw. Ausführzungen zurück in glatter Berührung mit dem Zylinderumfang, daß sie über Leitrollen laufen, die hierbei dicht an diese Zungen zu liegen kommen, sich aber während der Druckperiode zwecks ungestörten Entnehmend des Bogens durch die Greifer wieder heben.The invention relates to a printing machine with a vibrating printing cylinder and a Ribbon guide for the sheet both during printing and the next Submission to the executive bodies. With a machine of this type, keep the Guide straps, one end of which is attached to the cylinder, while the bow of the unwinding back to the contact or discharge tabs in smooth contact with the cylinder circumference that they run over guide rollers, which come to lie close to these tongues, but themselves during the printing period for the purpose of undisturbed removal of the sheet by the gripper raise again.
Durch diese Anordnung wird verhindert, daß die hintere Kante des Bogens beim Rückrollen des Druckzylinders den Zylinder früh-This arrangement prevents the trailing edge of the sheet from rolling back of the printing cylinder, the cylinder
ao zeitig verläßt und dadurch die ordnungsmäßige Abführung des Bogens verhindert.ao leaves early and thus prevents the proper discharge of the sheet.
Auf der Zeichnung ist eine Ausführungsform des Erfindungsgegenstandes beispielsweise dargestellt.An embodiment of the subject matter of the invention is shown in the drawing, for example shown.
Abb. ι zeigt einen Schnitt durch den Druckzylinder und die mit demselben arbeitenden Teile vor Beginn des Druckganges.Fig. Ι shows a section through the printing cylinder and the parts working with the same before the start of the print run.
Abb. 2 ist ein Schnitt durch die gleichen Teile während der Ausführung des gedruckten Bogens.Fig. 2 is a section through the same parts during the execution of the printed Bow.
Die periodisch um den Druckzylinder sich schlingenden und von diesem sich abwickelnden Bänder sind mit α bezeichnet. Sie sind mit dem einen Ende bei b am Druckzylinder, mit dem andern auf bandmaßartig arbeitenden· Winden c befestigt und über das am Ende der Schwingarme d sitzende Röllchen e geführt. Die Schwiiigarme d sind auf der vor- und rückwärts gedrehten Spindel / verkeilt und nehmen demgemäß bald eine gegen den Druckzylinder geneigte, bald eine vom Zylinder entferntere Stellung ein. In dem ersten Falle wird die Bänderzuführung um den Druckzylinder gegen die Anlegezungen zum Zwecke der Ableitung der Hinterkante des gedruckten Bogens über die Ausführzungen g verlängert, während im zweiten Falle eine entsprechende Verkürzung der Bänderführung eintritt, wodurch eine Beeinträchtigung der Wirkungsweise der Greifer am Druckzylinder bei der Übernahme eines auf den Anlegetisch h frisch angelegten Bogens vermieden wird.The bands looping periodically around the printing cylinder and unwinding from it are denoted by α. They are fastened with one end at b on the printing cylinder, with the other on winches c that work like a tape measure and are guided over the roller e located at the end of the swing arms d. The arms d are wedged on the forwards and backwards rotated spindle / and accordingly assume a position inclined towards the printing cylinder, now a position further away from the cylinder. In the first case, the ribbon feed around the printing cylinder is extended against the application tongues for the purpose of diverting the trailing edge of the printed sheet over the execution tongues g, while in the second case a corresponding shortening of the ribbon guide occurs, whereby the operation of the gripper on the printing cylinder is impaired Acquisition of a sheet freshly laid on the feed table h is avoided.
Mit Vorteil kann die Kippbewegung der Schwingarme d zur Bewegung eines den Bogen glattstreichenden Organs (wie Bürste, Filzzylinder o. dgl.) ausgenutzt werden, derart, daß während des Druckganges, also bei gehobenen Armen d und abgelenkten Bändern, das Streichorgan auf den Bpgen einwirkt, während dasselbe beim Abrollen des Bogens, d. h. bei gegen den Druckzylinder geneigten Armen, wieder abgehoben wird.Advantageously, the tilting movement of the swing arms d can be used to move an organ (such as a brush, felt cylinder or the like) which smoothes the sheet, so that the stroking element acts on the sheets during the printing process, i.e. when the arms d are raised and the ribbons are deflected , while the same is lifted off again when the sheet is unrolled, ie when the arms are inclined towards the printing cylinder.
