Abstract

Device for aligning sheets by the front edge comprises a number of lay marks (2) consisting of front marks (4) and top marks (3), which are moved from a position on the feed table (1), in which the top marks catch the sheets and the front marks form a feed line, into a position below the feed table and thus out of the path of the sheets. The lay marks are pivotably arranged on an eccentric mark shaft so that they correspond with clamping rings rotationally fixed on the mark shaft. Each front mark is supported in its position on the feed table against a driven element (21) of a control mechanism (22). Preferred Features: A driven rocker (17) of a coupling mechanism (14) is rotationally fixed to the mark shaft to move the lay marks from the position on the feed table into the position below the feed table.

Description

Die Erfindung betrifft eine Einrichtung zum Ausrichten von Bogen nach der Vorderkante mit einer Anzahl von aus einer Vordermarke und Deckmarke bestehenden Anlegmarken, die aus einer Position an einem Anlegtisch, in der die Deckmarken einen auszurichtenden Bogen fangen und die Vordermarken eine Anleglinie bilden, in eine Position unter den Anlegtisch und damit aus der Bahn der Bogen bringbar sind.
In Bogendruckmaschinen besteht das Erfordernis, einerseits die Anlegmarken, die aus Deckund Vordermarken bestehen, aus einer Position am Anlegtisch in eine Position unter dem Anlegtisch und damit aus der Bahn der Bogen sowie wieder zurück zum Anlegtisch zu bewegen, andererseits müssen die Deckmarken, welche die von einem Bändertisch auf den Anlegtisch geförderten Bogen fangen und damit ein Überschießen dieses Bogens verhindern, auf die Stärke der zur Verarbeitung gelangenden Bedruckstoffe eingestellt werden. Außerdem ist es erforderlich, um ein passerhaltiges Bedrucken des zur Verarbeitung gelangenden Materials zu sichern, die Vordermarken einzeln oder in ihrer Gesamtheit differenziert in oder entgegen der Förderrichtung zu verstellen und diese so dem tatsächlichen Verlauf der Bogenkante des zur Verarbeitung gelangenden Verarbeitungsgutes anzupassen.The invention relates to a device for aligning sheets to the leading edge with a number of feed marks consisting of a front mark and cover mark, which from one position on a feed table, in which the cover marks catch a sheet to be aligned and the front marks form a contact line, into one position under the feed table and thus the sheet can be brought out of the way.
In sheetfed printing machines, there is the requirement, on the one hand, to move the feed marks, which consist of cover and front marks, from a position on the feed table to a position under the feed table and thus out of the path of the sheets and back again to the feed table; catch a sheet conveyed sheet on the feed table and thus prevent this sheet from overshooting, be adjusted to the thickness of the printing material to be processed. In addition, it is necessary to ensure that the material to be processed is printed in register, to adjust the front marks individually or in their entirety differently in or against the conveying direction and to adapt them to the actual course of the sheet edge of the material to be processed.

Aus der DE 42 43 585 C2 ist eine derartige Einrichtung bekannt. Bei dieser Einrichtung sind die Anlegmarken jeweils starr an einer Koppel eines als Doppelschwinge ausgebildeten Gelenkvierecks angeordnet. Die Gestellpunkte der Doppelschwinge sind in einer schwingbeweglich gelagerten Abtriebsschwinge eines Stellgetriebes aufgenommen, während mit der Antriebsschwinge der Doppelschwinge eine Abtriebsschwinge eines vorgeordneten Antriebsgetriebes verbunden ist.
Nachteilig bei dieser Einrichtung ist der zur Realisierung erforderliche hohe Aufwand, da jeder Anlegmarke eine derartige Getriebeanordnung zugeordnet ist. Außerdem ist es von Nachteil, dass die Anlegmarken keine aktive Fangbewegung ausführen und die Anlegmarken in der die Anleglinie realisierenden Position, bedingt durch ihre Eigenmasse, bei hohen Arbeitsgeschwindigkeiten zu Schwingungen angeregt werden, die während der Ausrichtphase zu Anlagepasserdifferenzen führen.Such a device is known from DE 42 43 585 C2. In this device, the contact marks are each rigidly arranged on a coupling of a quadrangle formed as a double rocker. The frame points of the double rocker are accommodated in an output rocker of an actuating gear which is mounted such that it can oscillate, while an output rocker of an upstream drive gear is connected to the drive rocker of the double rocker.
A disadvantage of this device is the high outlay required for implementation, since such a gear arrangement is assigned to each contact mark. In addition, it is disadvantageous that the contact marks do not carry out an active catching movement and the contact marks in the position realizing the contact line, due to their inherent mass, are excited to vibrate at high working speeds, which lead to differences in register during the alignment phase.

Aufgabe der Erfindung ist es, eine gattungsgemäße Einrichtung zu schaffen, die mit einem geringen Aufwand zu realisieren ist, durch eine Fangbewegung ein Überschießen von Bogen verhindert und auch bei hohen Arbeitsgeschwindigkeiten einen guten Anlagepasser ermöglicht. The object of the invention is to provide a generic device with a low effort can be achieved by overshooting arches by a catching movement prevented and enables a good system registration even at high working speeds.

Erfindungsgemäß wird die Aufgabe durch eine Einrichtung gemäß den Merkmalen des Anspruchs 1 gelöst.
Durch die erfindungsgemäße Lösung wird eine Einrichtung zum Ausrichten von Bogen nach der Vorderkante geschaffen, die mit einfachen Mitteln zu realisieren ist und durch eine zusätzlich ausgeführte Fangbewegung ein Überschießen von Bogen verhindert. Infolge des Anlegens der Vordermarken an die Abtriebsglieder von Stellgetrieben werden Schwingungen der Anlegmarken auch bei hohen Arbeitsgeschwindigkeiten unterdrückt und damit ein exakter Anlagepasser gesichert.According to the invention the object is achieved by a device according to the features of claim 1.
The solution according to the invention creates a device for aligning sheets towards the leading edge, which can be implemented with simple means and prevents an overshooting of sheets by an additional catch movement. As a result of the application of the front marks to the output elements of actuating gears, vibrations of the application marks are suppressed even at high working speeds, thus ensuring an exact registration.

In Fig. 1 ist das Getriebeschema der Einrichtung mit einem Anlegtisch 1 und einer Anlegmarke 2, die aus einer Deckmarke 3 und einer Vordermarke 4 besteht, dargestellt. Der Antrieb der Anlegmarken 2 erfolgt über ein Kurvengetriebe 5, das aus einer Kurvenscheibe 10 besteht, an der eine Kurvenrolle 6 abläuft, die in einem Rollenhebel 7 gelagert ist. Der Rollenhebel 7 ist in einem Gestellpunkt 8 angeordnet, der in einer Kulisse 9 geführt ist und durch eine Stelleinrichtung 11 in der Kulisse 9 verschoben werden kann. Die Kurvenrolle 6 wird durch eine am Rollenhebel 7 angreifende Druckfeder 12 in Wirkverbindung mit der Kurvenscheibe 10 gehalten. Mit dem Rollenhebel 7 ist eine Antriebsschwinge 13 eines nachgeordneten Koppelgetriebes 14 biegesteif verbunden. Über eine Koppel 15 ist eine in einem Gestellpunkt 16 gelagert Abtriebsschwinge 17 an der Antriebsschwinge 13 angelenkt. Die Abtriebsschwinge 17 ist als ternäres Getriebeglied ausgebildet und das freie Ende mit einem' Gelenk 18 versehen. Eine Drehachse 16.1 des Gestellpunktes 16 und eine Schwenkachse 18.1 des Gelenkes 18 sind in einem Abstand e angeordnet. Im Gelenk 18 ist die Vordermarke 4 schwenkbar gelagert und wird durch eine Zugfeder 20 gegen einen biegesteif mit der Abtriebsschwinge 17 verbundenen Anschlag 19 gezogen. Im dem Anschlag 19 abgewandten Bereich korrespondiert die Vordermarke 4 mit einem Abtriebsglied 21 eines Stellgetriebes 22. Das Abtriebsglied 21 ist als ein in einer Geradführung 23 gelagertes Schiebeglied ausgebildet, das am der Vordermarke 4 zugewandten Ende mit einer Rolle 34 und am der Vordermarke abgewandten Ende mit einem Gleitstein 35 versehen ist, der in eine Führung eines Antriebsgliedes 23 eingreift. Das Antriebsglied 23 ist in einem Gestellpunkt 24 schwenkbar gelagert und biegesteif mit einem Zahnsegment 25 verbunden, in das ein Ritzel 26 eines Stellmotors 27 eingreift.
Da es erforderlich ist, die Anlegmarken 2 in Abständen nebeneinander über die Breite des Anlegtischs 1 verteilt anzuordnen, sind die Anlegmarken 2 auf einer exzentrischen Markenwelle 28 angeordnet (Fig. 2). Die Markenwelle 28 ist in Wänden 29 drehbar gelagert und mit dem Abtriebsglied 21 drehfest verbunden. Damit kann die Markenwelle 28, initiiert durch das Kurvengetriebe 5 und das Koppelgetriebe 14, um die Drehachse 16.1 verdreht werden. Auf der Markenweile 28 sind versetzt um den Abstand e schwenkbar um die Schwenkachse 18.1 mittels eines Lagerrings 30 die Anlegmarken 2 vorgesehen. Die Lagerringe 30 weisen jeweils einen Lagerhebel 30.1 auf. Jedem Lagerring 30 ist auf der Markenwelle 28 ein Klemmring 31 zugeordnet. Die Klemmringe 31 sind jeweils mittels einer Klemmschraube 32 verdrehfest auf der Markenwelle 28 angeordnet und mit einem Klemmhebel 31.1 versehen. Am Klemmhebel 31.1 ist der Anschlag 19 positioniert, gegen den der Lagerhebel 30.1 des Lagerrings 30 durch die Zugfeder 20, die am Lagerhebel 30.1 und am Klemmhebel 31.1 angreift, geführt wird.
Auf bekannte Weise werden Bogen von einem nicht dargestellten Bändertisch auf den Anlegtisch 1 und mit der Vorderkante gegen die in ihrer Position am Anlegtisch 1 befindlichen Vordermarken 4 gefördert und so nach der Vorderkante ausgerichtet. Nachfolgend kann eine Ausrichtung nach der Seitenkante erfolgen. Danach werden die Anlegmarken 2 durch ein Drehen der Markenwelle 28 um die Drehachse 16.1 aus ihrer Position am Anlegtisch 1 in eine Position unter den Anlegtisch 1 verbracht. Dazu läuft die Kurvenrolle 6 von einer hohen Rast auf eine niedere Rast, so dass die Abtriebsschwinge 17 entgegen dem Uhrzeigersinn verdreht wird. Bei der Bewegung in die Position unter den Anlegtisch 1 folgen die Anlegmarken 2 einem Wegverlauf 33. Danach bewegen sich die Anlegmarken 2 bei Bewegungsbeginn nahezu senkrecht zum Anlegtisch 1, d.h. die Deckmarken 3 heben vom Anlegtisch 1 ab, folgen dann einem etwa kreisförmigen Bahnabschnitt und werden so aus der Bahn der Bogen gebracht, so dass der auf dem Anlegtisch 1 befindliche Bogen durch nicht dargestellte Mittel abgeführt werden kann. Anschließend werden die Anlegmarken 2 zurückgeführt zum Anlegtisch 1, die Kurvenrolle 6 läuft von einer niederen Rast auf eine hohe Rast, wodurch die Abtriebsschwinge 17 im Uhrzeigersinn verdreht wird, wobei die Deckmarken 3 dem Wegverlauf 33 folgen. Bevor die Deckmarken 3 den etwa senkrecht zum Anlegtisch 1 gerichteten Wegverlauf 33 beschreiben, legen die Vordermarken 4 an den Rollen 34 des Stellgetriebes 22 an, wobei jeder Anlegmarke 2 ein Stellgetriebe 22 zugeordnet ist. Durch das Anlegen der Vordermarken 4 an den Rollen 34 werden die Vordermarken 4 entgegen der Wirkung der Zugfeder 20 auf der Markenwelle 28 um die Schwenkachse 18.1 geringfügig geschwenkt und so die Schar der Vordermarken 4, eine Anleglinie bildend, ausgerichtet. In dieser Position wird der Folgebogen gegen die Vordermarken 4 transportiert und damit gefangen. D.h. ein Überschießen von Bogen über die Deckmarken 3 wird sicher verhindert. Nachfolgend bewegen sich die Vordermarken 4 in Wirkverbindung mit den Rollen 34 stehend, etwa senkrecht in Richtung des Anlegtischs 1, bis die dem Anlegtisch 1 zugewandte Seite der Deckmarken 3 und die Oberfläche des Anlegtischs 1 einen vorgebbaren, durch die Materialdicke des zur Verarbeitung gelangenden Bogen bestimmten Abstand realisieren. Der Abstand kann verändert werden, indem der Gestellpunkt 8 mittels der Stelleinrichtung 11 in der Kulisse 9 verschoben wird.
Da jeder Anlegmarke 2 ein Stellgetriebe 22 zugeordnet ist, wobei über den Stellmotor 27 und die Wirkpaarung Ritzel 26/Zahnsegment 25 das Antriebsglied 23 geschwenkt und damit das Abtriebsglied 21 mit der Rolle 34 auf die Vordermarke 4 zu- oder von dieser wegbewegt werden kann, können die Vordermarken 4 einzeln beliebig verstellt werden. Damit ist es möglich, die Anleglinie geradlinig, konkav oder konvex auszubilden. Außerdem ist es möglich, einzelne Anlegmarken 2 abzustellen oder die Anleglinie in ihrer Gesamtheit beliebig zu verschieben. In Fig. 1, the transmission diagram of the device with a feed table 1 and a feed mark 2, which consists of a cover mark 3 and a front mark 4, is shown. The feed marks 2 are driven via a cam mechanism 5, which consists of a cam plate 10 on which a cam roller 6 runs, which is mounted in a roller lever 7. The roller lever 7 is arranged in a frame point 8 which is guided in a link 9 and can be moved in the link 9 by an adjusting device 11. The cam roller 6 is held in operative connection with the cam disc 10 by a compression spring 12 acting on the roller lever 7. With the roller lever 7, a drive rocker 13 of a downstream linkage 14 is rigidly connected. An output rocker 17 mounted in a frame point 16 is articulated on the drive rocker 13 via a coupling 15. The output rocker 17 is designed as a ternary gear member and the free end is provided with a joint 18. An axis of rotation 16.1 of the frame point 16 and a pivot axis 18.1 of the joint 18 are arranged at a distance e. The front mark 4 is pivotally mounted in the joint 18 and is pulled by a tension spring 20 against a rigidly connected stop 19 connected to the output rocker 17. In the area facing away from the stop 19, the front mark 4 corresponds to an output element 21 of an actuating gear 22. The output element 21 is designed as a slide element mounted in a straight guide 23, which has a roller 34 at the end facing the front mark 4 and an end facing away from the front mark a sliding block 35 is provided which engages in a guide of a drive member 23. The drive member 23 is pivotally mounted in a frame point 24 and rigidly connected to a toothed segment 25, in which a pinion 26 of a servomotor 27 engages.
Since it is necessary to arrange the application marks 2 next to one another at intervals along the width of the application table 1, the application marks 2 are arranged on an eccentric brand shaft 28 (FIG. 2). The marker shaft 28 is rotatably mounted in walls 29 and connected to the driven member 21 in a rotationally fixed manner. The marker shaft 28, initiated by the cam mechanism 5 and the coupling mechanism 14, can thus be rotated about the axis of rotation 16.1. On the marker shaft 28, the contact marks 2 are provided, offset by the distance e and pivotable about the pivot axis 18.1 by means of a bearing ring 30. The bearing rings 30 each have a bearing lever 30.1. Each bearing ring 30 is assigned a clamping ring 31 on the brand shaft 28. The clamping rings 31 are each arranged in a rotationally fixed manner on the mark shaft 28 by means of a clamping screw 32 and are provided with a clamping lever 31.1. The stop 19 is positioned on the clamping lever 31.1, against which the bearing lever 30.1 of the bearing ring 30 is guided by the tension spring 20 which acts on the bearing lever 30.1 and on the clamping lever 31.1.
In a known manner, sheets are conveyed from a belt table (not shown) onto the feed table 1 and with the front edge against the front marks 4 located in their position on the feed table 1 and thus aligned with the front edge. You can then align it to the side edge. Thereafter, the contact marks 2 are moved from their position on the feed table 1 to a position under the feed table 1 by rotating the mark shaft 28 about the axis of rotation 16.1. For this purpose, the cam roller 6 runs from a high rest to a low rest, so that the output rocker 17 is rotated counterclockwise. When moving into the position under the feed table 1, the feed marks 2 follow a path 33. Then the feed marks 2 move almost perpendicular to the feed table 1 at the start of the movement, ie the cover marks 3 lift off the feed table 1, then follow an approximately circular path section and become brought from the path of the sheet so that the sheet located on the feed table 1 can be removed by means not shown. Then the contact marks 2 are returned to the feed table 1, the cam roller 6 runs from a low rest to a high rest, whereby the output rocker 17 is rotated clockwise, the cover marks 3 following the path 33. Before the cover marks 3 describe the path 33 directed approximately perpendicularly to the feed table 1, the front marks 4 put on the rollers 34 of the actuating gear 22, with each feed mark 2 being assigned an actuating gear 22. By placing the front marks 4 on the rollers 34, the front marks 4 are pivoted slightly against the action of the tension spring 20 on the mark shaft 28 about the pivot axis 18.1 and thus aligning the family of the front marks 4, forming a contact line. In this position, the following sheet is transported against the front marks 4 and thus caught. This means that overshooting of sheets over the cover marks 3 is reliably prevented. Subsequently, the front marks 4 move in operative connection with the rollers 34, approximately vertically in the direction of the feed table 1, until the side of the cover marks 3 facing the feed table 1 and the surface of the feed table 1 have a predeterminable one, determined by the material thickness of the sheet to be processed Realize distance. The distance can be changed by moving the frame point 8 in the setting 9 by means of the adjusting device 11.
Since each contact mark 2 is assigned an actuating gear 22, the drive member 23 being pivoted via the servo motor 27 and the effective pairing of pinion 26 / toothed segment 25, and thus the driven member 21 with the roller 34 can be moved toward or away from the front mark 4 the front marks 4 can be individually adjusted as desired. This makes it possible to make the contact line straight, concave or convex. In addition, it is possible to park individual contact marks 2 or to move the entire contact line as desired.
