Abstract
Description
Falzwerk für Papierbogen Die Erfindung be-trifft ein Falzwerk für Papierbogen, das insbesondere zur Anordnung vor einer Sammelheftmaschine bestimmt, aber auch für andere Zwecke verwendbar ist. Folding unit for sheets of paper The invention relates to a folding unit for Sheets of paper intended in particular to be placed in front of a saddle stitcher, but can also be used for other purposes.
Bekannte Falzwerke für Papierbogen sind so ausgebildet, daß die gefalzten Bogen das Falzwerk mit der Falzkante voran verlassen. Infolgedessen ist es nicht möglich, die gefalzten Bogen unmittelbar der Sammelkette einer Heftmaschine zuzuführen, weil dazu die Falzkante des Bogens nach oben gerichtet sein müßte.Known folding mechanisms for sheets of paper are designed so that the folded Sheets leave the folding unit with the folding edge first. As a result, it is not possible to feed the folded sheets directly to the saddle chain of a stitching machine, because for this the folded edge of the sheet would have to be directed upwards.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Falzwerk für Papierbogen zu schaffen, das es ermöglicht, die gefalzten Bogen mit einfachen Mitteln und hoher Geschwindigkeit unmittelbar mit der offenen Seite nach unten gerichtet der Sammelkette einer Heftmaschine zuzuführen.The invention is therefore based on the object of a folding mechanism for sheets of paper to create that makes it possible to produce the folded sheets with simple means and high Speed immediately with the open side facing down the saddle chain to be fed to a stapler.
Die Lösung dieser Aufgabe besteht erfindungsgemäß darin, daß dem Falzwerk eine Vorrichtung zum Wenden der gefalzten Bogen nachgeordnet und dieser Wendevorrichtung Mittel zum offenen der gefallen Bogen nachgeordnet sind. Bei einer bevorzugten Ausführungsform ist das Falzwerk als Taschenfalzwerk ausgebildet und weist eine nach Art einer Falztasche ausgebildete, mit einem federnden Anschlag für die Falzkante der Bogen versehene zusätzliche Tasche auf, die so angeordnet ist, daß die yefalzten Bogen nach dem Verlassen der letzten Falztasche mit der E'alzkante voran unmittelbar in die Wendetasche einlaufen ac anschließend von oben her mit der offenen Seite voran einer in bekannter Weise mit zwei gegenläufig rotierenden Saugwalzen ausgestatteten äffnungsvorrichtung zugeführt werden.The solution to this problem is, according to the invention, that the folding unit a device for turning the folded sheets is arranged downstream and this turning device Means to open the fallen bow are subordinate. In a preferred embodiment is the folding mechanism is designed as a pocket folding mechanism and has one in the manner of a folding pocket trained, provided with a resilient stop for the folded edge of the sheet additional pocket, which is arranged so that the folded sheets after Leave the last folding pocket with the edge leading directly into the reversible pocket then enter ac from above with the open side first, one in known Way with two counter-rotating suction rolls equipped opening device are fed.
Weitere Einzelheiten der erfindung sind aus der nachfolgenden Beschreibung und der Zeichnung eines Ausführungsbeispieles zu entnehmen, und zwar zeigt die Zeichnung ein Falzwerk mit einer Falztasche 1, einer Wendet asche 2 und insgesamt sieben Förderwalzen 3 bis 9, ferner eine mit zwei an sich bekannten Saugwalzen 10 und 11 ausgestattete Vorrichtung zum Öffnen der gefalzten Bogen und die Sammelket-te 12 einer Heftmaschine im Querschnitt.Further details of the invention are from the following description and to be taken from the drawing of an exemplary embodiment, namely the drawing shows a folding unit with a folding pocket 1, a turning ash 2 and a total of seven conveyor rollers 3 to 9, furthermore one equipped with two suction rolls 10 and 11 known per se Device for opening the folded sheets and the collecting chain 12 of a stapling machine in cross section.
Die zu falzenden Papierbogen a werden in bekannter Weise von einem nicht gezeigten Stapel abgenommen und einzeln den gegenläufig rotierenden Walzen 3 und 4 sowie durch letztere bis zu einem verstellbaren Anschlag 13 in die Tasche 1 eingeführt.The sheets of paper to be folded a are in a known manner by a not shown stack removed and individually the counter-rotating rollers 3 and 4 and through the latter up to an adjustable stop 13 in the pocket 1 introduced.
Sodann erfolgt in bekannter Weise zwischen den gegenläufig rotierenden Walzen 4 und 5 die Bildung des Falzes. Der so gefalzte Bogen wird mit der Falzkante voran durch ein Leitblech 14 den ebenfalls gegenläufig rotierenden Walzen 5 und 6 und von diesen in die Tasche 2 eingeführt, in der ein in Längsrichtung der Tasche verstellbarer, federnder Anschlag 15 vorgesehen ist.Then takes place in a known manner between the counter-rotating Rollers 4 and 5 form the fold. The sheet folded in this way becomes with the folded edge ahead by a guide plate 14 also counter-rotating rollers 5 and 6 and inserted from these into the pocket 2, in which one in the longitudinal direction of the pocket adjustable, resilient stop 15 is provided.
Dieser Anschlag wird jeweils so eingestellt, daß nach dem Auftreffen der Falzkan-te eines Bogens a das dadurch bewir]cte Ausweichen und anschließende Zurückfedern des Anschlages 15 die offene Seite des gefalzten Bogens die in der Zeichnung gestrichelt angedeutete Lage einnimmt, in welcher der Bogen von den gegenläufig rotierenden Walzen 6 und 7 erfaßt und durch die ebenfalls gegenläufig rotierenden Walzen 8 und 9 dem Saugwalzenpaar 10 und 11 zugeführt wird, durch das der Bogen in der dargestellten Weise geöffnet und direkt der Sammelkette 12 einer Heftmaschine zugeführt wird.This stop is set so that after impact the folded edge of a sheet a the resulting deflection and subsequent Spring back of the stop 15 the open side of the folded sheet in the Drawing assumes position indicated by dashed lines, in which the arc of the opposite directions rotating rollers 6 and 7 detected and also rotating in opposite directions Rolls 8 and 9 is fed to the pair of suction rollers 10 and 11, through which the sheet in the illustrated Way opened and directly to the saddle chain 12 is fed to a stapler.
Die so ausgebildete Falz-, Wende- und Öffnungsvorrichtung zeichnet sich durch einfachen Aufbau und große Betriebssicherheit aus und ermöglicht das Arbeiten mit hohen Geschwindigkeiten.The folding, turning and opening device designed in this way draws is characterized by a simple structure and high operational reliability and makes this possible Working at high speeds.
Naturgemäß sind die Ausführungsmöglichkeiten der Erfindung durch das dargestellte Ausführungsbeispiel nicht erschöpft, So ist es beispielsweise möglich, anstelle des dargestellten und beschriebenen Einfach-Taschenfalzwerkes ein Mehrfach-Taschenfalzwer]c oder auch ein Schwertfalzwerk vorzusehen. Ferner kann in der Wendetasche 2 anstelle des federnden Anschlages 15 auch ein im Arbeitstakt des Falzwerkes gesteuerter Anschlag vorgesehen werdenNaturally, the implementation options of the invention by the The illustrated embodiment is not exhausted, so it is possible, for example, instead of the single pocket folder shown and described, a multiple pocket folder] c or to provide a knife folding unit. Furthermore, in the reversible pocket 2 instead of the resilient stop 15 is also a stop controlled in the working cycle of the folding unit are provided
