Description

Die Erfindung betrifft eine Vordermarke zum Ausrichten von in einer Bogentransportrichtung auf einen Anlegtisch geförderter Bogen nach der Vorderkante, wobei eine Schar von Vordermarken verteilt über die Breite des Anlegtischs zwischen einer Ausrichtlage am Anlegtisch sowie einer vom Anlegtisch entfernten Rastlage einem Geschwindigkeitsprofil folgend verbringbar ausgeführt sind und die Vordermarken in ihrer Position in der Ausrichtlage in Kontakt mit innerhalb eines Stellbereichs einstellbaren Anschlagmitteln stehen.The invention relates to a front mark for aligning conveyed in a sheet transport direction on a feed table sheet after the front edge, wherein a crowd of front marks distributed over the width of the feed table between an alignment position on the feed table and a remote from the feed table locking position following a speed profile are carried out and the Front mark in their position in the alignment position in contact with adjustable within a control range stop means are.

Derartige Vordermarken sind allgemein bekannt. In der EP 538 638 werden Vordermarken beschrieben, die aus einem eigenfedernden Material bestehen und gemeinsam auf einer Markenwelle angeordnet sind. Die Markenwelle wird mittels eines Kurvengetriebes zyklisch geschwenkt, wodurch die auf der Markenwelle angeordneten Vordermarken im Maschinentakt aus ihrer Rastlage unter dem Anlegtisch in die Arbeitslage am Anlegtisch und nach dem Ausrichten eines Bogens wieder zurück in die Rastlage geschwenkt werden. Der Weg der Vordermarke ist so bemessen, dass diese in ihrer Arbeitslage gegen ein im Anlegtisch vorgesehenes Anleglineal geführt und so gegen die Wirkung des eigenfedernden Materials ausgerichtet werden. Am Anleglineal sind den einzelnen Vordermarken zugeordnete Anschläge vorgesehen, die durch an den Anschlägen angreifende Steuerelemente in ihrer Position verändert werden können. Entsprechend der Position der Anschläge können einzelne Vordermarken oder die Schar der Vordermarken in ihrer Gesamtheit verstellt und damit die durch die Vordermarken vergegenständlichte Anleglinie in oder entgegen der Bogentransportrichtung verschoben, schräg gestellt sowie konkav oder konvex ausgebildet werden.Such leading brands are well known. In the EP 538 638 are described front brands, which consist of a self-resilient material and are arranged together on a brand shaft. The brand wave is cyclically pivoted by means of a cam gear, whereby the arranged on the brand shaft front marks are pivoted in the machine cycle from its rest position under the feed table in the working position on the feed table and after aligning a sheet back into the rest position. The path of the leading edge is dimensioned such that they are guided in their working position against a Anlegglineal provided in the feed table and are aligned against the action of the inherent springing material. At Anleglineal the individual front brands associated attacks are provided, which can be changed by attacking the attacks controls in position. According to the position of the attacks individual leading brands or the crowd of frontal brands can be adjusted in their entirety, and thus the objectified by the front brands Anleglinie moved in or against the sheet transport direction, tilted and formed concave or convex.

Es ist auch bekannt, die Vordermarken an sich biegesteif auszubilden und der gemeinsamen Markenwelle so zu zuordnen, dass diese entgegen der Wirkung eines Kraftspeichers beim Anlegen an am Anlegtisch vorgesehenen einstellbaren Anschlägen relativ zur Markenwelle verstellt werden können. Damit können die Vordermarken einzeln oder in der Gesamtheit den Erfordernissen angepasst werden.It is also known to form the leading brands rigidly and to assign the common brand shaft so that they can be adjusted against the action of an energy storage when creating at the feed table provided adjustable stops relative to the brand shaft. Thus, the front brands can be adjusted individually or in the whole of the requirements.

Aus der DE 195 46 066 C2 sind weiterhin Vordermarken bekannt, die mittels einer Blattfeder und einer Druckfeder jeweils in einem Markengehäuse gelagert und die Markengehäuse drehfest mit einer Markenwelle verbunden sind. In ihrer Arbeitslage werden die Vordermarken gegen ein Anlegmittel geführt, das in seiner Position und seiner Form veränderbar ist, so dass die Vordermarken gegen den aus Blatt- und Druckfeder bestehenden Kraftspeicher derart verschoben werden, dass die gewünschte Anleglinie realisiert wird.From the DE 195 46 066 C2 are also leading brands known, which are mounted by means of a leaf spring and a compression spring in each case in a brand-name housing and the brand name housing rotatably connected to a brand shaft. In their working position, the leading brands are guided against a landing means, which is changeable in its position and its shape, so that the leading brands against the existing of leaf and compression spring Force memory can be moved so that the desired Anlegg line is realized.

Bei diesen Vordermarken ist es von Nachteil, dass es nicht möglich ist, für alle Positionen der Vordermarken in ihrer Arbeitslage am Anlegtisch eine optimierte Aufprall- und Abhebgeschwindigkeit zu realisieren. Vielmehr wird die Aufprall- und Abhebgeschwindigkeit in dem Maß vergrößert, in dem die Position der Vordermarken in Bogentransportrichtung verschoben wird. Die hohen Aufprall- und Abhebgeschwindigkeiten führen zu Verschleiß an den Vordermarken und den Anschlägen, so dass eine ständige Nachjustierung erforderlich ist. Außerdem wird ein hoher Lärmpegel emittiert, bei hohen Arbeitsgeschwindigkeiten der Anlagepasser durch das Prellverhalten der Vordermarken nachteilig beeinflusst und Schwingungen in das System eingeleitet, die zum Dublieren führen können.With these front lays it is disadvantageous that it is not possible to realize an optimized impact and lift-off speed for all positions of the front lays in their working position at the feed table. Rather, the impact and Abhebgeschwindigkeit is increased to the extent in which the position of the leading brands is moved in the sheet transport direction. The high impact and Abhebgeschwindigkeiten lead to wear on the leading brands and the attacks, so that a constant readjustment is required. In addition, a high noise level is emitted, adversely affected by the bounce behavior of the leading brands at high operating speeds of the investment fit and initiated vibrations in the system, which can lead to doubling.

Aufgabe der Erfindung ist es, als Anschlagmarken ausgebildete Vordermarken so in ihrer Arbeitslage zu positionieren, dass eine Erhöhung des Lärmpegels und eine nachteilige Beeinflussung der Qualität des Verarbeitungsgutes in Abhängigkeit von der Position der Vordermarken ausgeschlossen ist.The object of the invention is to position stop marks formed as leading brands in their working position that an increase in the noise level and an adverse effect on the quality of the processed material is excluded depending on the position of the leading brands.

Erfindungsgemäß wird die Aufgabe durch die Merkmale des Anspruchs 1 gelöst.According to the invention the object is achieved by the features of claim 1.

Durch die erfindungsgemäße Lösung ist es möglich, als Anschlagmarken ausgebildete Vordermarken ohne großen Aufwand und ohne nachteilige Wirkung innerhalb des von den Anschlagmitteln zu realisierenden Stellbereichs zu positionieren. Insbesondere wird es vermieden, das Druckergebnis nachteilig beeinflussende Impulse in das System einzuleiten, wobei eine Erhöhung des Lärmpegels vermieden wird.The solution according to the invention makes it possible to position leading marks formed as stop marks without great effort and without adverse effect within the setting range to be realized by the stop means. In particular, it is avoided to initiate the printing result adversely influencing impulses in the system, with an increase in the noise level is avoided.

In one embodiment, the invention is explained in detail. In the drawings show:

In der Fig. 1 ist eine Vordermarke 1 in Seitenansicht gezeigt, die eine zu einem Anlegtisch 2 gewandte Anschlagfläche 3 aufweist. Die Vordermarke 1 ist einem Markenhebel 4 zugeordnet, der biegesteif ausgeführt und mittels eines Bolzens 5 drehbeweglich in einem Halter 6 gelagert ist. Der Halter 6 ist drehfest mit einer Markenwelle 7 verbunden. Der Halter 6 weist einen Ansatz 8 auf, der mit einem Anschlag 9 korrespondiert, welcher dem Markenhebel 4 zugeordnet ist. Durch eine zwischen dem Markenhebel 4 und dem Halter 6 vorgesehene Druckfeder 10 wird der Anschlag 9 des Markenhebels 4 gegen den Ansatz 8 des drehfest mit der Markenwelle7 verbundenen Halters 6 geführt.In the Fig. 1 a front marker 1 is shown in side view, which has a facing to a feed table 2 stop surface 3. The front mark 1 is associated with a brand lever 4, which is rigid and mounted by a bolt 5 rotatably mounted in a holder 6. The holder 6 is rotatably connected to a brand shaft 7. Of the Holder 6 has a projection 8, which corresponds to a stop 9, which is associated with the brand lever 4. By a provided between the brand lever 4 and the holder 6 compression spring 10, the stop 9 of the brand lever 4 is guided against the projection 8 of the rotatably connected to the Markenwelle7 holder 6.

Auf der Markenwelle 7 sind beabstandet zueinander die Halter 6 mit den schwenkbar aufgenommenen Markenhebeln 4 und damit den Vordermarken 1 angeordnet (Fig. 2). Diese über die Breite des Anlegtischs 2 angeordneten Vordermarken 1 bilden eine Anleglinie. An der Markenwelle 7 greift ein Markenantrieb 11 an, der die Markenwelle 7 zyklisch im Arbeitstakt schwenkt und damit die Vordermarken 1 aus ihrer am Anlegtisch 2 gelegenen Arbeitslage in die unter dem Anlegtisch 2 gelegene Rastlage sowie zurück in die Arbeitslage führt. Der Markenantrieb 11 kann als Markengetriebe 12, bekanntermaßen als Kurvengetriebe 13 ausgebildet sein.On the brand shaft 7 are spaced from each other, the holder 6 with the pivotally received brand levers 4 and thus the front lays 1 arranged ( Fig. 2 ). These arranged over the width of the feed table 2 front lays 1 form an Anleglinie. At the brand shaft 7 engages a brand drive 11, which pivots the brand shaft 7 cyclically in the power stroke and thus leads the front lays 1 from its lying on the feed table 2 working position in the location below the feed table 2 detent position and back to the working position. The brand drive 11 can be designed as a brand transmission 12, known as a cam gear 13.

Die Schwenkbewegung der Markenwelle 7 ist so bemessen, dass die Vordermarken 1 in ihrer am Anlegtisch 2 gelegenen Arbeitslage mit einem unter dem Anlegtisch 2 gelegenen Teil der Anschlagfläche 3 gegen im Bereich des Anlegtischs 2 positionierte Anschlagmittel 14 geführt werden, wobei die Anschlagmittel 14 im Ausführungsbeispiel als Anschlagbolzen 15 ausgeführt sind. Beim Anlegen der Vordermarken 1 an den Anschlagbolzen 15 werden die Vordermarken 1 gegen die Wirkung der Druckfeder 10 verschoben. Die Anschlagbolzen 15 sind an der Unterseite des Anlegtischs 2 oder durch andere Mittel geführt. Die einzelnen Anschlagbolzen 15 sind mit Stellhebeln 16 verbunden, die schwenkbar auf einer Stellwelle 17 gelagert sind. Am dem Anschlagbolzen 15 abgewandten Ende greift jeweils ein Stellelement 18 an. Durch Betätigung der Stellelement 18 können die Anschlagbolzen 15 in oder entgegen einer Bogenförderrichtung 19, in der die Bogen von einem nicht dargestellten Bändertisch auf den Anlegtisch 2 und mit der Bogenvorderkante gegen die Anschlagflächen 3 der Vordermarken 1 geführt werden, innerhalb eines Stellbereichs s verschoben werden. So können einzelne Vordermarken 1 verstellt, die Gesamtheit der Vordermarken 1 und damit die durch diese gebildete Anleglinie innerhalb der von den Anschlagbolzen 15 realisierbaren Stellbereichs s positioniert, die Anleglinie schräg gestellt oder konkav bzw. konvex ausgebildet werden. Um unabhängig von der Position der jeweiligen Aufpralllage bzw. Abheblage innerhalb des Stellbereichs s der Anschlagbolzen 15 gleiche Aufprall- bzw. Abhebgeschwindigkeiten realisieren zu können, folgen der Markenantrieb 11 bzw. das Markengetriebe 12 einem Bewegungsgesetz, das ein Geschwindigkeitsprofil 22 mit einer ersten Rast 20 und einer zweiten Rast 21 aufweist. Die erste Rast 20 und die zweite Rast 21 sind betragsmäßig gleich groß. In Fig. 4 ist ein derartiges Geschwindigkeitsprofil 22 über einen Maschinenwinkel ϕ aufgetragen. Aus dem Geschwindigkeitsprofil 22 ist zu erkennen, dass über einen Drehwinkel ϕ = 210° bis 360° die Vordermarken 1 in einer beliebigen Position innerhalb des Stellbereichs s der Anschlagbolzen 15 an diesem anliegen. Beginnend bei etwa ϕ = 0° werden von dem durch den Markenantrieb 11 oder das Markengetriebe 12 realisierte Bewegungsgesetz mit einem ansteigenden Geschwindigkeitsverlauf über etwa 15° die Vordermarken 1 von den Anschlagbolzen 15 entfernt, so dass die durch das Anlegen der Vordermarken 1 an den Anschlagbolzen 15 entgegen der Wirkung der Druckfeder 10 realisierte Verschiebung aufgehoben und der Anschlag 9 gegen den Ansatz 8 geführt wird. Daran schließt sich die zweite Rast 21 des Geschwindigkeitsprofils 22 an, in der die Vordermarken 1 in ihrer Gesamtheit in einer gleichförmigen Geschwindigkeit den Stellbereich s der Anschlagbolzen 15 durchlaufen und sich damit von diesen entfernen, ohne störende Impulse zu initiieren und diese in das System einzuleiten. Das Geschwindigkeitsprofil 22 zeigt weiter, dass nachfolgend mit einer sich erhöhenden Geschwindigkeit v die Vordermarken 1 vom Anlegtisch 2 entfernt und in die momentane Rastlage unter dem Anlegtisch 2 geführt werden. Dabei wird die Geschwindigkeit v vermindert, etwa bei einem Maschinenwinkel ϕ = 105° die Richtung umgekehrt und dem entsprechenden Geschwindigkeitsprofil 22 folgend zum Anlegtisch 2 zurückgeführt. Bevor die Vordermarken 1 den Stellbereich s der Anschlagbolzen 15 erreichen, beginnt die erste Rast 20 des Geschwindigkeitsprofils 22 (ϕ = 180°). Damit legen sich die Gesamtheit der Vordermarken 1, unabhängig von der Position der zugeordneten Anschlagbolzen 15 innerhalb des Stellbereichs s, mit einer gleichen Geschwindigkeit v an. Nach dem Anlegen der Vordermarken 1 an den Anschlagbolzen 15 wird ein von die Position der Anschlagbolzen 15 abhängiger Überweg kompensiert, indem die Druckfedern 10 zusammengedrückt und die Anschlage 9 von den Ansätzen 8 abheben. Nach dem Durchlaufen der ersten Rast 20 (ϕ = 200°) im Geschwindigkeitsprofil 22 wird die Geschwindigkeit v weiter verringert bis zu einem Wert v = 0 bei etwa ϕ = 210°.The pivotal movement of the brand shaft 7 is dimensioned such that the front lays 1 are guided in its working position 2 located at the working position with a located below the feed table 2 part of the stop surface 3 against positioned in the region of the feed table 2 stop means 14, wherein the stop means 14 in the embodiment as Stop bolts 15 are executed. When creating the front lays 1 to the stop pin 15, the front lays 1 are moved against the action of the compression spring 10. The stop pins 15 are guided on the underside of the feed table 2 or by other means. The individual stop pins 15 are connected to adjusting levers 16 which are pivotally mounted on a control shaft 17. At the stop pin 15 opposite end in each case an actuating element 18 engages. By actuation of the actuator 18, the stopper pin 15 in or against a sheet conveying direction 19, in which the sheets are guided by a belt table, not shown on the feed table 2 and the sheet leading edge against the stop surfaces 3 of the front lays 1, within a setting range s. Thus, individual front lays 1 can be adjusted, the entirety of the front lays 1 and thus the Anleglinie formed by this positioning within the realizable by the stop pin 15 adjusting range s, the Anleglinie be inclined or concave or convex. In order to realize the same impact or Abhebgeschwindigkeiten 15 regardless of the position of the respective impact position or Abheblage within the setting range s of the stop pin, the brand drive 11 and the market gear 12 follow a law of motion, the speed profile 22 with a first catch 20 and having a second latch 21. The first latch 20 and the second latch 21 are equal in magnitude. In Fig. 4 such a velocity profile 22 is plotted over a machine angle φ. From the speed profile 22 it can be seen that over a rotation angle φ = 210 ° to 360 °, the leading brands 1 in any position within the control range s of Stop bolt 15 abut this. Beginning at about φ = 0 ° are from the realized by the brand drive 11 or the vehicle transmission 12 law of motion with a rising speed over about 15 °, the front lays 1 of the stopper pin 15, so that by applying the front lays 1 to the stop pin 15th lifted against the action of the compression spring 10 realized displacement and the stopper 9 is guided against the projection 8. This is followed by the second latch 21 of the speed profile 22, in which the front lays 1 in their entirety in a uniform speed through the adjustment range s of the stop pin 15 and thus move away from them, without initiating disturbing pulses and initiate them into the system. The speed profile 22 further shows that the front lays 1 are subsequently removed from the feed table 2 with an increasing speed v and are guided into the current latching position under the feed table 2. In this case, the speed v is reduced, for example at a machine angle φ = 105 °, the direction reversed and the corresponding velocity profile 22 following fed back to feed table 2. Before the leading brands 1 reach the setting range s of the stop pins 15, the first stop 20 of the velocity profile 22 (φ = 180 °) begins. Thus, the entirety of the front lays 1, regardless of the position of the associated stop pin 15 within the control range s, at a same speed v at. After applying the front lays 1 to the stop pin 15 a dependent of the position of the stop pin 15 over-travel is compensated by the compression springs 10 compressed and lift off the stopper 9 of the lugs 8. After passing through the first stop 20 (φ = 200 °) in the velocity profile 22, the velocity v is further reduced to a value v = 0 at about φ = 210 °.
