A row of suckers and a pair of conveyor rollers are disposed between the sheet feeder and the impression cylinder. An uppermost sheet of a stack of sheets is liftable at a leading edge thereof by the row of suckers over and beyond stack stops of the stack stop assembly and being feedable to the pair of conveyor rollers for advancing the uppermost sheet to the sheet stops formed on the impression-cylinder grippers. The stack stop assembly includes swivel bearings supporting the stack stops, respectively, at both sides thereof, each of the stack stops having a journal pin to which a pivot arm is secured.

Description

Die Erfindung bezieht sich auf einen Stapelanschlag am Bogenanleger von Druckmaschinen gemäß dem Oberbegriff des Anspruches 1.The invention relates to a stack stop on the sheet feeder of printing machines according to the preamble of claim 1.

Um einen paßgenauen Druck und einen sicheren Lauf bei der Verarbeitung von Papierbögen bei Druckmaschinen zu bekommen, ist es nötig, den Bogen in Lauf- und in seitlicher Richtung vor dem Drucken gegen Anschläge zu führen und hiermit auszurichten. Hierzu ist an der vorderen, der Arbeitsmaschine zugekehrten Seite des Papierstapels ein Stapelanschlag vorgesehen, mit dem insbesondere die obersten Lagen des Bogenstapels ausgerichtet werden.In order to get a precisely fitting print and a safe run when processing paper sheets in printing presses, it is necessary to guide the sheet in the running and lateral directions against printing and to align it with it. For this purpose, a stack stop is provided on the front side of the paper stack facing the working machine, with which the uppermost layers of the sheet stack in particular are aligned.

Der oberste Papierbogen wird mit einem schwenkbaren Saugersystem der Stapelanlage entnommen und einem Transportwalzenpaar zugeführt, das den Bogen mit einer konstanten Umfangsgeschwindigkeit, die größer als die Umfangsgeschwindigkeit des Druckzylinders ist, bis an den Papieranschlag im Druckzylinder weitertransportiert. Der Papieranschlag kann hierbei im Greifersystem des Druckzylinders vorgesehen sein. Wenn der Bogen mit einer leichten Bauschung an diesem anliegt und von den Greifern sicher gehalten wird, beenden die Transportwalzen den Transport des Bogens. Hierzu werden sie, über eine Kurvenscheibe gesteuert, voneinander getrennt.The uppermost paper sheet is removed from the stacking system with a swiveling suction system and fed to a pair of transport rollers, which transport the sheet at a constant peripheral speed, which is greater than the peripheral speed of the printing cylinder, to the paper stop in the printing cylinder. The paper stop can be provided in the gripper system of the printing cylinder. If the sheet lies against it with a slight bulge and is held securely by the grippers, the transport rollers stop the sheet from being transported. To do this, they are separated from each other, controlled by a cam.

Bei der Verarbeitung von unterschiedlichen Papierqualitäten kommt es insbesondere bei dickeren Papieren zu unerwünscht großen Bauschungen, die zu starken Geräuschen und Beschädigungen an der Papiervorderkante durch den Anschlag im Druckzylinder führen können. Das dickere Papier wird, wenn es durch das Saugersystem den.Transportwalzen zugeführt ist, früher erfaßt als dünnere Bogen, so daß es härter auf den Anschlag im Druckzylinder auftrifft und somit ein größeres Geräusch verursacht. Auch bei Transportende, wenn die Transportwalzen sich trennen, wird das dickere Papier gegenüber dem dünneren eine längere Zeit und somit einen längeren Weg transportiert.When processing different paper qualities, especially with thicker papers, undesirably large bulges occur, which can lead to strong noises and damage to the leading edge of the paper due to the stop in the printing cylinder. The thicker paper, when it is fed through the suction system to the transport rollers, is caught earlier than thinner sheets, so that it hits the stop in the impression cylinder harder and thus causes a greater noise. Even at the end of the transport, when the transport rollers separate, the thicker paper is transported for a longer time and thus a longer way than the thinner one.

Zu dieser zwangsläufigen Erscheinung kommen weitere Faktoren wie Differenzen beim Ansaugen und Lösen der Bögen durch das Saugersystem, Übergabe an die Transportwalzen und Schlupf zwischen den Transportwalzen, die die unterschiedlichen Transportzeiten noch verstärken können. All diese Erscheinungen können zu einer Verstärkung des Geräusches, dem sogenannten Papierknall, führen.In addition to this inevitable phenomenon, there are other factors such as differences in the suction and loosening of the sheets by the suction system, transfer to the transport rollers and slippage between the transport rollers, which can increase the different transport times. All of these phenomena can lead to an amplification of the noise, the so-called paper bang.

Die Aufgabe der Erfindung ist es, mit einfachen Mitteln den Weg zwischen dem Stapelanschlag des Papierstapels und dem Anschlag im Druckzylindergreifer so verändern zu können, daß für jede Papierqualität und Stärke der Transportweg und damit die Bauschung des Bogens optimal eingestellt werden kann.The object of the invention is to be able to change the path between the stack stop of the paper stack and the stop in the impression cylinder gripper so that the transport path and thus the bag of the sheet can be optimally adjusted for each paper quality and thickness.

Die Aufgabe wird mit den Merkmalen des Kennzeichens des Anspruches 1 gelöst, wobei durch einfaches Betätigen des Schwenkhebels der Stapelanschlag in seiner Stellung zum Bogenstapel hin so verändert werden kann, daß bei minimalem Geräusch eine optimale Anlage des zugeführten Bogens an den Bogenanschlägen der Greifer und somit eine sichere Mitnahme des Bogens durch die Greifer gewährleistet ist. Ein weiterer Vorteil ist, daß durch ein Verschwenken des Stapelanschlags unterschiedliche Papierstärken und Schlupfauswirkungen in den Transportmitteln ausgeglichen werden können.The object is achieved with the features of the characterizing part of claim 1, the position of the stacking stop being able to be changed by simply actuating the pivoting lever in such a way that the sheet is fed optimally against the sheet stops of the gripper and thus with minimal noise safe gripping of the sheet is guaranteed by the gripper. Another advantage is that by swiveling the stack stop different paper thicknesses and slip effects in the means of transport can be compensated.

Die Unteransprüche kennzeichnen vorteilhafte Ausgestaltungen der in Anspruch 1 wiedergegebenen Lösung, so daß der Vorteil erreicht wird, unter Verwendung von einfachsten Mitteln eine leicht zu bedienende Vorrichtung zu schaffen, die insbesondere bei kleinen Druckmaschinen den Erfordernissen der Praxis entspricht.The subclaims characterize advantageous embodiments of the solution reproduced in claim 1, so that the advantage is achieved using the simplest means to create an easy-to-use device which, in particular in the case of small printing machines, corresponds to practical requirements.

Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen schematisch dargestellt. Es zeigt:

  • Fig. 1 eine Seitenansicht einer Stapelanlage,
  • Fig. 2 eine Teil- Draufsicht auf die Stapelanlage.
An embodiment of the invention is shown schematically in the drawings. It shows:
  • 1 is a side view of a stacking system,
  • Fig. 2 is a partial plan view of the stacking system.

In Figur 1 ist ein Teil eines ansich bekannten Offsetdruckwerkes dargestellt mit einem Druckzylinder 1 und einem Gummizylinder 2, der mit einem nicht dargestellten Platten zylinder zusammenwirkt, dem wiederum in bekannter Weise ein Farb-Feuchtwerk zugeordnet ist. Der Druckzylinder 1 ist hierbei mit Greifern 3 zum Transport der Bögen versehen, die Bogenanschläge 4 aufweisen. Das Transportwalzenpaar 5 transportiert den zugeführten Bögen 6 bis an den besagten Bogenanschlag 4 mit einer etwas höheren Geschwindigkeit als die Umfangsgeschwindigkeit des Druckzylinders 1. Nachdem sich der Bogen leicht gebauscht hat und sicher von den Greifern 3 gehalten wird, erfolgt ein voneinander Abheben des Transportwalzenpaares 5 über eine nicht dargestellte Steuereinrichtung.In Figure 1, a part of a known offset printing unit is shown with a printing cylinder 1 and a rubber cylinder 2, which cooperates with a plate cylinder, not shown, which in turn is assigned a ink dampening unit in a known manner. The printing cylinder 1 is provided with grippers 3 for transporting the sheets, which have sheet stops 4. The pair of transport rollers 5 transports the supplied sheets 6 up to said sheet stop 4 at a somewhat higher speed than the peripheral speed of the printing cylinder 1. After the sheet has bulged slightly and is securely held by the grippers 3, the pair of transport rollers 5 is lifted apart a control device, not shown.

Die zuzuführenden Papierbögen werden mit einem schwenkbaren Saugersystem 7 von dem Bogenstapel 8 entnommen und dem Transportwalzenpaar 5 zugeführt. Insbesondere bei kleinem Bogenformat genügt zum Ausrichten derselben in Laufrichtung ein Stapelanschlag 9, an den sich die Bögen anlegen. Durch die nicht dargestellte Stapelhubeinrichtung wird die Oberkante des Bogenstapels 8 immer in etwa gleicher Höhe gehalten.The sheets of paper to be fed are removed from the sheet stack 8 with a swiveling suction system 7 and fed to the pair of transport rollers 5. In particular in the case of a small sheet format, a stack stop 9 against which the sheets lie is sufficient to align them in the running direction. The upper edge of the sheet stack 8 is always held at approximately the same height by the stack lifting device, not shown.

Die Stapelanschläge 9 sind beiderseits über Schwenkzapfen 10 in Schwenklagern 11 gelagert, die wiederum an einer Gestelltraverse 12 befestigt sind. Die Gestelltraverse 12 ist zwischen den beiden Seitengestellen 13 vorgesehen und mit diesen verschraubt.The stacking stops 9 are supported on both sides via pivot pins 10 in pivot bearings 11, which in turn are fastened to a frame cross member 12. The frame cross member 12 is provided between the two side frames 13 and screwed to them.

An einem Schwenkzapfen 10 des Stapelanschlages 9 ist ein Schwenkhebel 14 befestigt, der seitlich des Bogenstapels 8 zu dessen hinterem Ende reicht und über einen Bremsbolzen 15 in einem Langloch 16 einer am Seitengestell 13 befestigten Platine 17 geführt ist. Über den Schwenkhebel 14 läßt sich somit der Stapelanschlag 9 in Papierlaufrichtung zum Stapel hin verschwenken, wodurch sich der Weg zwischen der Papiervorderkante in der Anlage am Stapelanschlag 9 und dem Bogenanschlag 4 im Druckzylinder 1 stufenlos verändern läßt, was zu unterschiedlichen Papierbauschungen führt. Durch die Schräglage des Stapelanschlages 9 in Richtung Bogenstapel 8 ist gewährleistet, daß die Papierbögen beim Nachsteigen des Tisches immer an den Stapelanschlag gedrückt werden.On a pivot pin 10 of the stack stop 9, a pivot lever 14 is fastened to the side of the sheet stack 8 the rear end of which extends and is guided via a brake bolt 15 in an elongated hole 16 of a circuit board 17 fastened to the side frame 13. Via the pivot lever 14, the stack stop 9 can thus be pivoted in the paper running direction towards the stack, so that the path between the paper leading edge in the system on the stack stop 9 and the sheet stop 4 in the printing cylinder 1 can be changed continuously, which leads to different paper bulges. The inclined position of the stack stop 9 in the direction of the sheet stack 8 ensures that the paper sheets are always pressed against the stack stop when the table is climbed.

Im gezeigten Ausführungsbeispiel ist der Stapelanschlag 9 als Hohlkörper ausgebildet und weist im Bereich der Stapeloberkante Blasöffnungen 18 auf, die über eine Zuleitung 19 an eine nicht dargestellte Druckluft-Versorgung angeschlossen sind. Die Blasöffnungen 18 am Stapelanschlag 9 dienen zur Auffächerung der Papierbögen in der Anlagestellung, um das Abheben des jeweils obersten Bogens beim Zuführen in die Maschine zu erleichtern. Zum seitlichen Ausrichten des Bogenstapels sind Anschläge 20 vorgesehen.In the exemplary embodiment shown, the stack stop 9 is designed as a hollow body and has blow openings 18 in the region of the top edge of the stack, which are connected via a feed line 19 to a compressed air supply, not shown. The blowing openings 18 on the stack stop 9 serve to fan out the paper sheets in the contact position in order to facilitate the lifting of the top sheet in each case when it is fed into the machine. Stops 20 are provided for laterally aligning the sheet stack.

In Figur 2 ist eine Draufsicht insbesondere auf den Stapelanschlag 9 mit dem Schwenkhebel 14 gezeigt, wobei die seitlichen Anschläge 20 für den Bogenstapel 8 nicht dargestellt sind.FIG. 2 shows a plan view, in particular of the stack stop 9 with the pivot lever 14, the side stops 20 for the sheet stack 8 not being shown.
