Description

Die Erfindung betrifft einen Bogenausleger für Druckmaschinen gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a sheet delivery for printing machines according to the preamble of claim 1.

Durch die DE-PS 20 47 808 ist ein derartiger Bogenausleger bekannt geworden. Dieser weist hintere Bogenanschläge auf, die beim Einschieben eines Hilfsablagetisches quer zu einer Bogentransportrichtung abgeschwenkt werden. Durch das Abschwenken der Bogenanschläge sind diese außer Funktion gesetzt. Um jedoch auch weiterhin eine Ausrichtung der auf den Hilfsablagetisch abgelegten Bogen vornehmen zu können, werden zusätzlich angeordnete Bogenanschläge auf den Hilfsablagetisch abgesenkt. Diese zusätzlichen Bogenanschläge sind mittels eines Hilfsgestänges mit den abschwenkbaren Bogenanschlägen verbunden. Nachteilig ist die Anordnung zusätzlicher Bogenanschläge und die aufwendige Konstruktion zu deren Betätigung. Weiterhin können Bogen, die während des Einschiebens des Hilfsablagetisches auf diesem abgelegt werden, durch das Herabsenken der zusätzlich vorgesehenen Bogenanschläge zwischen diesen und dem Hilfsablagetisch eingeklemmt werden. Hierdurch würden dann beim Herausziehen des Hilfsablagetisches eingeklemmte Bogen zerstört werden, was zu einer unkorrekten Stapelbildung führen würde und damit zu vorzeitigem Stapelwechsel oder gar Maschinenstop.Such a sheet delivery has become known from DE-PS 20 47 808. This has rear sheet stops, which are swiveled transversely to a sheet transport direction when an auxiliary storage table is inserted. By swiveling the sheet stops, they are disabled. However, in order to be able to continue to align the sheets deposited on the auxiliary deposit table, additionally arranged sheet stops are lowered onto the auxiliary deposit table. These additional bow stops are connected to the swing-away bow stops by means of an auxiliary linkage. The disadvantage is the arrangement of additional sheet stops and the complex construction for their actuation. Furthermore, sheets that are placed on the auxiliary storage table during the insertion of the auxiliary storage table can be clamped between the auxiliary storage table by lowering the additionally provided sheet stops. This would destroy any jammed sheets when the auxiliary storage table was pulled out, which would lead to incorrect stack formation and thus to premature stack change or even machine stop.

Der Erfindung liegt die Aufgabe zugrunde, einen einfachen Bogenanschlag für die Bogenhinterkante bei Auslegern an bogenverarbeitenden Maschinen zu schaffen, der eine Ausrichtung des Bogenhauptstapels in Bogentransportrichtung bewirkt und insbesondere beim Einschieben einer Zwischenstapeleinrichtung in den Bereich der abzulegenden Bogen verhindert, daß der oder die Bogen einer oberen Lage des Bogenhauptstapels wie auch die auf die Zwischenstapeleinrichtung aufgelegten Bogen durch das Einschieben der Zwischenstapeleinrichtung aus einer vorbestimmten, ausgerichteten Lage verschoben werden.The invention has for its object to provide a simple sheet stop for the sheet trailing edge on cantilevers on sheet-processing machines, which causes an alignment of the main sheet stack in the sheet transport direction and in particular when inserting an intermediate stacking device in the area of the sheets to be deposited prevents the sheet or sheets from an upper Position of the main sheet stack as well as the sheets placed on the intermediate stacking device can be shifted from a predetermined, aligned position by inserting the intermediate stacking device.

Die geltende Aufgabe wird erfindungsgemäß durch den kennzeichnenden Teil des Anspruchs 1 gelöst.The applicable task is solved according to the invention by the characterizing part of claim 1.

Die Vorteile der erfindungsgemäßen Bogenanschläge liegen insbesondere darin, daß sie die Nachteile des Standes der Technik vermeiden und darüberhinaus die Bogen des Hauptstapels während des Einschiebens einer Zwischenstapeleinrichtung weiterhin ausrichten. Die einfache Konstruktion ist kostengünstig herstellbar, ist störunanfällig und leicht zu handhaben, wodurch Wartungskosten und Stillstandszeiten der Maschine gesenkt werden.The advantages of the sheet stops according to the invention are in particular that they avoid the disadvantages of the prior art and, moreover, continue to align the sheets of the main stack during the insertion of an intermediate stacking device. The simple construction is inexpensive to manufacture, is not susceptible to faults and is easy to use, which reduces maintenance costs and machine downtimes.

Ein Bogenausleger 1 für eine Druckmaschine weist ein Kettenrad 2 und eine umlaufende, endlose Kette 3 auf, an der Bogengreifereinrichtungen 4 angeordnet sind. Die Bogen 6 werden von einer nicht dargestellten Druckmaschine bedruckt und von den Bogengreifern 4 über einen Bogenhauptstapel 7 transportiert, über welchem sie an vorgegebener Stelle ihren Greiferschluß öffnen und den Bogen 6 fallenlassen. Hierbei wird die Bogenhinterkante von einer Bremseinrichtung 8 (z.B. Saugwalze) gehalten, welche die Geschwindigkeit des Bogens verzögert. Die Bremseinrichtung 8 ist in einer zwischen Gestellwänden 9,11 des Bogenauslegers 1 horizontal verschiebbaren Traverse (nicht dargestellt) gelagert. Die Traverse kann aufgrund ihrer horizontalen Verschiebbarkeit auf verschiedene Bogenformate eingestellt werden.A sheet delivery 1 for a printing press has a chain wheel 2 and a revolving, endless chain 3, on which sheet gripper devices 4 are arranged. The sheets 6 are printed by a printing machine, not shown, and transported by the sheet grippers 4 via a main sheet stack 7, via which they open their gripper closure at a predetermined point and drop the sheet 6. Here, the trailing edge of the sheet is held by a braking device 8 (e.g. suction roller), which decelerates the speed of the sheet. The braking device 8 is mounted in a crossbar (not shown) which can be displaced horizontally between the frame walls 9, 11 of the sheet boom 1. The traverse can be adjusted to different arch formats due to its horizontal displaceability.

Unterhalb der Bremseinrichtung 8 ist eine horizontal in Bogentransportrichtung oszillierende Leiste 13 vorgesehen. Die Leiste 13 weist zu diesem Zweck einen mit der Leiste 13 fest verbundenen Schlitten 12 auf. Der Schlitten 12 ist jeweils an seiner auf die Gestellwand 9;11 weisenden Seite mit zwei drehbar gelagerten Rollen 41,42 versehen, die in einer gestellwandfesten Führung 43 horizontal geführt werden. Eine erste Rolle 41 steht hierbei jeweils in Kontakt mit einem exzentrisch zur Bremseinrichtung 8 angeordneten Nocken 46. Eine Druckfeder 44 stützt sich auf ihrer einen Seite jeweils an der Gestellwand 9;11 und auf der anderen Seite am Schlitten 12 ab. Eine durch den Nocken 46 aufgezwungene, horizontale Auslenkung des Schlittens 12 erfolgt gegen die Rückstellkraft der Druckfeder 44.Below the braking device 8 there is a bar 13 which oscillates horizontally in the sheet transport direction. For this purpose, the strip 13 has a carriage 12 which is fixedly connected to the strip 13. The carriage 12 is provided on its side facing the frame wall 9; 11 with two rotatably mounted rollers 41, 42, which are guided horizontally in a guide 43 fixed to the frame wall. A first roll 41 is in each case in FIG Contact with a cam 46 arranged eccentrically to the braking device 8. A compression spring 44 is supported on one side in each case on the frame wall 9, 11 and on the other side on the slide 12. A horizontal deflection of the slide 12 forced by the cam 46 takes place against the restoring force of the compression spring 44.

An der Leiste 13 sind in einem Abstand a voneinander zwei Bolzen 16,17 vorgesehen, auf denen jeweils ein Bogenanschlag 18;19 schwenkbar angeordnet ist. Die Bogenanschläge 18;19 werden zusammen mit der Leiste 13 in bzw. gegen die Bogentransportrichtung bewegt und stoßen dabei an eine Bogen- bzw. Bogenstapelhinterkante. Hierbei werden die auf den Bogenhauptstapel 7 abgelegten Bogen 6 gegen einen vorderen Bogenanschlag 39 geschoben und ausgerichtet.On the bar 13 two bolts 16, 17 are provided at a distance a from one another, on each of which a bow stop 18, 19 is arranged pivotably. The sheet stops 18, 19 are moved together with the bar 13 in or against the sheet transport direction and thereby abut a sheet or sheet stack trailing edge. Here, the sheets 6 deposited on the main sheet stack 7 are pushed and aligned against a front sheet stop 39.

Die Bogenanschläge 18,19 sind so lang ausgeführt, daß sie einen oberen Bereich des Bogenhauptstapels 7 überdecken und somit auch für die Bogen des oberen Bereichs einen Anschlag bilden.The sheet stops 18, 19 are so long that they cover an upper area of the main sheet stack 7 and thus also form a stop for the sheets of the upper area.

Beim Einschub einer Zwischenstapeleinrichtung 21 in den Bereich der abzulegenden Bogen 6 werden sowohl die Bogen 6 auf dem Bogenhauptstapel 7 als auch die Bogen 6 auf einem Zwischenstapel 25 auf der Zwischenstapeleinrichtung 21 mittels der oszillierenden Bogenanschläge 18,19 ausgerichtet.When an intermediate stacking device 21 is inserted into the area of the sheets 6 to be deposited, both the sheets 6 on the main sheet stack 7 and the sheets 6 on an intermediate stack 25 on the intermediate stacking device 21 are aligned by means of the oscillating sheet stops 18, 19.

Die Bogenanschläge 18,19 wirken während der Trennung des unteren Bogenhauptstapels 7 von einem oberen Zwischenstapel 25 solange auf die Hinterkanten beider Stapel 7,25, bis die Zwischenstapeleinrichtung 21 mit ihrer Vorderkante die Bogenanschläge erreicht hat. In diesem Moment ist der obere Zwischenstapel 25 vom unteren Bogenhauptstapel 7 getrennt. Eine Ausrichtung des unteren Bogenhauptstapels 7 ist nicht mehr notwendig, daher werden die Bogenanschläge 18,19 beim Einschieben der Zwischenstapeleinrichtung 21, vorzugsweise bei Kontakt der Zwischenstapeleinrichtung 21 mit den Bogenanschlägen 18,19 quer zur Bogentransportrichtung bzw. quer zur Einschubrichtung der Zwischenstapeleinrichtung 21 um den Bolzen 16;17 nach oben geschwenkt, bis sie auf der Oberfläche der Zwischenstapeleinrichtung 21 zu liegen kommen. Eine oszillierende Bewegung der Bogenanschläge 18, 19 erfolgt daraufhin in Kontakt mit der Oberfläche der Zwischenstapeleinrichtung 21.The sheet stops 18, 19 act during the separation of the lower main sheet stack 7 from an upper intermediate stack 25 on the trailing edges of both stacks 7, 25 until the intermediate stacking device 21 with its front edge Has reached bow stops. At this moment, the upper intermediate stack 25 is separated from the lower main sheet stack 7. Alignment of the lower main sheet stack 7 is no longer necessary, therefore the sheet stops 18, 19 become transversely to the sheet transport direction or transversely to the direction of insertion of the intermediate stacking device 21 around the bolt when the intermediate stacking device 21 is inserted, preferably when the intermediate stacking device 21 comes into contact with the sheet stops 16; 17 pivoted upwards until they come to rest on the surface of the intermediate stacking device 21. An oscillating movement of the sheet stops 18, 19 then takes place in contact with the surface of the intermediate stacking device 21.

Die Schwenkbewegung der Bogenanschläge 16,17 wird durch eine Einrichtung am Vorderteil der Zwischenstapeleinrichtung 21 ausgelöst. Zu diesem Zweck weist die Zwischenstapeleinrichtung 21 in einem Abstand b (b < a) zwei Schrägen 23,24 auf, deren Verlängerungen 26,27 sich unter einem spitzen Winkel α (z.B. 90°) schneiden, wobei die unter dem Winkel α gebildete Spitze 28 in Einschubrichtung der Zwischenstapeleinrichtung 21, also entgegen der Bogentransportrichtung, weist.The pivoting movement of the sheet stops 16, 17 is triggered by a device on the front part of the intermediate stacking device 21. For this purpose, the intermediate stacking device 21 has at a distance b (b <a) two bevels 23, 24, the extensions 26, 27 of which intersect at an acute angle α (for example 90 °), the tip 28 formed at the angle α points in the direction of insertion of the intermediate stacking device 21, that is, counter to the sheet transport direction.

Eine auf die Bogenanschläge 18,19 nach unten wirkende Kraft wird allein durch die Schwerkraft der Bogenanschläge 18,19 aufgebracht. Es ist jedoch auch denkbar, diese mittels Zug-oder Druckfedern zu verstärken. Die Bogenanschläge 18,19 hängen in Grundstellung, d.h. wenn eine Hauptstapelplatte 31 soweit abgeschwenkt ist, daß sie keinen Kontakt mehr mit den Bogenanschlägen 18,19 aufweist, stets um einen kleinen Winkel β (ca. 15°) zur Vertikalen 29,30 geneigt. Durch diese Anordnung wird erreicht, daß die Hauptstapelplatte 31 beim Hochfahren im z.B. leeren Zustand durch Kontaktieren der Bogenanschläge 18,19 diese in eine Schwenkbewegung versetzt, so daß die Bogenanschläge 18,19 nur durch ihr Eigengewicht belastet auf der Hauptstapelplatte 31 aufliegen.A force acting downward on the arch stops 18, 19 is applied solely by the gravity of the arch stops 18, 19. However, it is also conceivable to reinforce them by means of tension or compression springs. The sheet stops 18, 19 hang in the basic position, ie when a main stacking plate 31 is pivoted so far that it no longer has any contact with the sheet stops 18, 19, always inclined at a small angle β (approx. 15 °) to the vertical 29.30. This arrangement ensures that the main stacking plate 31st when starting up in the empty state, for example, by contacting the sheet stops 18, 19, these are pivoted so that the sheet stops 18, 19 rest on the main stacking plate 31 only under their own weight.

Die Zwischenstapeleinrichtung 21 ist in einfacher Bauweise als Stapelplatte ausgeführt und weist an ihren Seitenkanten 32,33 jeweils eine Anzahl drehbar gelagerter Rollen 34,36 auf, mittels derer sie in Schienen 37,38 leicht verschiebbar horizontal geführt wird. Die Schienen 37,38 sind an den Gestellwänden 9,11 befestigt.The intermediate stacking device 21 is of simple construction as a stacking plate and has on its side edges 32, 33 in each case a number of rotatably mounted rollers 34, 36, by means of which it is guided horizontally in rails 37, 38 in an easily displaceable manner. The rails 37, 38 are fastened to the frame walls 9, 11.

Der vordere Bogenanschlag 39 ist unterhalb des Kettenrades 2 vorgesehen und schwenkbar an den Gestellwänden 9,11 befestigt.The front bow stop 39 is provided below the sprocket 2 and is pivotally attached to the frame walls 9, 11.
