An aligning device for sheet deliveries of printing presses which includes fixed sheet stops for the front edge of the delivery stack, fixed sheet stops for the back edge of the delivery stack, and movable brush sheet stops for the back edge of the delivery stack having a sheet brake disposed thereon oriented transverse to the direction of sheet movement. The brush sheet stops comprising one or more recessed brushes having firm bristles which are directed at a forwardly and downwardly inclined angle.

Description

Die Erfindung betrifft eine Ausrichteeinrichtung für Bogenauslagen von Druckmaschinen nach dem Oberbegriff des ersten Patentanspruches.The invention relates to an alignment device for sheet deliveries of printing machines according to the preamble of the first claim.

Eine Ausrichteeinrichtung genannter Gattung ist aus der DE-OS 3 127 540 bekannt. Von Nachteil ist, daß durch die Anordnung der Bürsten an beiden Seiten in der Bogenauslage die Ausrichtung zur Vorderkante infolge von seitlichen Rückfederungen der von abzulegenden Bogen zuvor mitgenommenen Borsten zwangsläufig unbestimmt ist. Außerdem besteht die Gefahr, daß Bogen beidseitig am freien Durchfallen gehindert werden. Von Nachteil ist ferner der aufwendige Antrieb für eine Rotationsbewegung der seitlich angebrachten Bürsten.An alignment device of the type mentioned is known from DE-OS 3 127 540. It is disadvantageous that the arrangement of the brushes on both sides in the sheet delivery means that the orientation to the front edge is inevitably indefinite as a result of lateral springbacks of the bristles previously carried by sheets to be deposited. There is also the risk that sheets are prevented from falling through on both sides. Another disadvantage is the complex drive for a rotational movement of the brushes attached to the side.

Der Erfindung liegt die Aufgabe zugrunde, eine einfache Vorrichtung genannter Gattung zu schaffen, mit der exakt bestimmte Stapelvorderkanten ermöglicht werden.The invention has for its object to provide a simple device of the type mentioned, with which precisely determined stack leading edges are made possible.

Der Vorteil der Erfindung besteht in der Verbesserung der Stapelvorderkantenausbildung in der Bogenauslage von Druckmaschinen. Diese definierte Stapelvorderkante wird bei der Weiterverarbeitung als Anlagekante benötigt.The advantage of the invention is the improvement of the formation of the leading edge of the stack in the sheet delivery of printing machines. This defined stack leading edge is required for further processing as a system edge.

Nachfolgend soll die Erfindung an einem Ausführungsbeispiel näher erläutert werden.

  • Es zeigt: Fig. 1 den Bogenausleger einer Druckmaschine in Seitenansicht,
  • Fig. 2 die Draufsicht nach Fig. 1, teilweise im Schnitt,
  • Fig. 3 eine Ansicht der Bürste (3) als Einzelheit,
  • Fig. 4 einen Schnitt A-A nach Fig. 2 durch die Bürste (3) als Einzelheit im vergrößerten Maßstab.
The invention will be explained in more detail below using an exemplary embodiment.
  • 1 shows the sheet delivery of a printing press in a side view,
  • 2 shows the top view of FIG. 1, partly in section,
  • 3 is a view of the brush (3) as a detail,
  • Fig. 4 shows a section AA of FIG. 2 through the brush (3) as a detail on an enlarged scale.

Gemäß Fig. 1 werden die bedruckten Bogen 9 durch Kettenförderer 4 über den Auslegerstapel gebracht und dort abgelegt. Ein auf- und abfahrbarer Tisch für den Hauptstapel 5 ist in der Zeichnung nicht dargestellt, während in Fig. 2 ein in U-Schienen 15, 16 einschiebbarer Hilfsablagetisch 12 für den Bogenstapel 6 zu sehen ist.1, the printed sheets 9 are brought by chain conveyors 4 over the delivery stack and placed there. A table that can be moved up and down for the main stack 5 is not shown in the drawing, while in FIG. 2 an auxiliary storage table 12 for the sheet stack 6 that can be inserted into U-rails 15, 16 can be seen.

Die Bogen werden nach öffnen der Greifer 8 durch eine Bogenbremse 7 abgebremst und gegen Bogenanschläge 11 für die Vorderkante ausgerichtet. Quer zur Bogenlaufrichtung sind an der Traverse 10 der Bogenbremse 7 neben festen Bogenanschlägen 1 für die Hinterkante Bürsten 3 in zugeordneten Ausnehmungen 19 weiterer fester Bogenanschläge 2 für die Hinterkante gegenüber der Anlagenseite des Bogens 9 angeordnet (Fig. 1 bis 4). Die Borsten 20 der Bürsten 3 sind nach unten schräggestellt und annähernd um den Differenzbetrag der Bogengröße innerhalb der größten Stapelfläche angeordnet. Die Tiefe des Hineinragens ist einstellbar und in Fig. 4 durch Pfeile angedeutet. Die Bürsten 3 besitzen nicht zu weiche Borsten 20, deren Schrägstellung nach unten mindestens 300 beträgt (Fig. 4).After opening the grippers 8, the sheets are braked by a sheet brake 7 and aligned against sheet stops 11 for the leading edge. Transversely to the sheet travel direction of B to the cross arm 10 ogenbremse 7 in addition to fixed sheet stops 1 for the trailing edge of the brush 3 in associated recesses 19 further fixed sheet stops 2 located on the trailing edge relative to the contact side of the sheet 9 (Fig. 1 to 4). The bristles 20 of the brushes 3 are inclined downwards and arranged approximately by the difference in the size of the sheets within the largest stacking area. The depth of the protrusion is adjustable and indicated by arrows in FIG. 4. The brushes 3 do not have to soft bristles 20 whose inclination downwards at least 30 is 0 (Fig. 4).

Dadurch wird erreicht, daß die Bogen 9 eine exakte Ausrichtung zur Anlagenseite erhalten, auch wenn aus Kostengründen Bogen in unterschiedlichen Größen, z.B. mit Unterschieden von 3 mm und mehr verarbeitet werden müssen. Kurze Bogen 9 fallen frei durch, während die langen Bogen 9 den elastischen Widerstand der Bürste 3 überwinden müssen. Länge und Stärke der Borsten 20 sowie deren Schrägungswinkel ist so gewählt, daß die Bogen 9 nicht in den Borsten 20 hängenbleiben und trotzdem noch eine ausreichende Schiebekraft vorhanden ist.This ensures that the sheets 9 are precisely aligned with the system side, even if sheets of different sizes, e.g. must be processed with differences of 3 mm and more. Short sheets 9 fall freely, while the long sheets 9 have to overcome the elastic resistance of the brush 3. The length and thickness of the bristles 20 and their helix angle is selected so that the bends 9 do not get caught in the bristles 20 and still have sufficient pushing force.

Die Bogenbremse 7 ist in Bogenlaufrichtung auf Führungsstangen 13, 14 verschiebbar angeordnet und zusammen mit den Bogenanschlägen 1, 2 für die Hinterkante und den in den Bogenanschlägen 2 integrierten Bürsten 3 auf das entsprechende Bogenformat einstellbar. Die Verschiebung erfolgt durch Verdrehen von Zahnrädern 17, 18, die mit an den Führungsstangen 13, 14 vorgesehenen Zähnen zusammenwirken.The sheet brake 7 is slidably arranged in the sheet running direction on guide rods 13, 14 and, together with the sheet stops 1, 2 for the trailing edge and the brushes 3 integrated in the sheet stops 2, can be adjusted to the appropriate sheet format. The displacement is carried out by turning gear wheels 17, 18 which cooperate with teeth provided on the guide rods 13, 14.

Die erfindungsgemäße Lösung ist nicht auf das beschriebene Ausführungsbeispiel mit einem Hilfsablagetisch 12 beschränkt, sondern sinngemäß für jede Art von Bogenauslegern zur sauberen Stapelausbildung zwischen festen Anschlägen bei Verarbeitung unterschiedlicher Bogengrößen vorteilhaft anwendbar.The solution according to the invention is not limited to the exemplary embodiment described with an auxiliary filing table 12, but can advantageously be used analogously for any type of sheet delivery for clean stack formation between fixed stops when processing different sheet sizes.
