Description

Verfahren und Einrichtung zum Ausrichten von BogenMethod and device for aligning sheets
Die Erfindung betrifft ein Verfahren und eine Einrichtung zum Ausrichten von auf einem Anlegtisch geförderten Bogen an in und/ oder quer zur Bogenf örderrichtung angeordneten Anschlägen.The invention relates to a method and a device for aligning sheets conveyed on a feed table to stops arranged in and / or transversely to the sheet conveying direction.
In Bogendruckmaschinen müssen die über den Anlegtisch der Druck¬ maschine zuzuführenden Bogen vor der Übernahme in die Druckma¬ schine in Bogenf örderrichtung und quer zur Bogenf örderrichtung ausgerichtet werden/ um eine hohe Druckqualität zu sichern.In sheet-fed printing presses, the sheets to be fed in via the feed table of the printing press must be aligned in the sheet conveying direction and transverse to the sheet conveying direction before being taken over into the printing press / in order to ensure high print quality.
Das Ausrichten in Bogenf örderrichtung erfolgt durch ständiges oder taktweises Fördern gegen Vorderanschläge. Für das ständige Fördern sind am Anlegtisch angeordnete Förderbänder (DE 39 17 072) und für das taktweise Fördern sind im Takt der Bogenf örderung gesteuerte Taktrollen (DD 139 706) bekannt.Alignment in the sheet conveying direction is carried out by constant or cyclical conveying against front stops. Conveyor belts (DE 39 17 072) arranged on the feed table are known for continuous conveying and clocked rollers (DD 139 706) are known for the cyclical conveying in time with the sheet conveying.
Für die seitliche Ausrichtung sind (DE 29 29 388) sog. Seiten- ziehmarken bekannt. Werden die Bogen mit zu geringer Kraft gegen die Anschläge gefördert/ erreichen sie die Anschläge nicht und es entstehen Ausrichtfehler. Der gleiche Effekt tritt auf/ wenn die Bogen mit hoher Geschwindigkeit an die Anschläge gefördert wer¬ den und anschließend zurückspringen. Ausrichtf fihler können auch entstehen/ wenn die Bogen mit hoher Kraft an die Anschläge ge¬ drückt werden und Bogenbauschen entstehen.So-called side draw marks are known for the lateral alignment (DE 29 29 388). If the sheets are conveyed against the stops with too little force, they will not reach the stops and alignment errors will occur. The same effect occurs / if the sheets are conveyed to the stops at high speed and then spring back. Alignment sensors can also occur / if the arches are pressed against the stops with high force and arches are formed.
Aus diesen Gründen sind die Ausrichteinrichtungen zur Vermeidung von Ausrichtfehlern kompliziert aufgebaut, erfordern hohen Ein¬ stellaufwand und trotzdem sind bei schneilauf enden Maschinen Aus¬ richtfehler nicht immer zu vermeiden.For these reasons, the alignment devices for avoiding alignment errors have a complicated structure, require a high adjustment effort and nevertheless alignment errors cannot always be avoided in machines that end in snow.
Aufgabe der Erfindung ist die Schaffung eines Verfahrens und ei¬ ner Einrichtung zur exakten Bogenausrichtung mit niedrigem Auf¬ wand. Erfindungsgemäß wird die Aufgabe durch die Merkmale der Patent¬ ansprüche gelöst.The object of the invention is to provide a method and a device for exact sheet alignment with little effort. According to the invention, the object is achieved by the features of the claims.

Auf einem Anlegtisch 1 einer nicht dargestellten Druckmaschine mit mindestens einem Anlagedruckwerk und gegebenenfalls weite¬ ren Druckwerken werden die von dem Anlagedruckwerk und den ge¬ gebenenfalls weiteren Druckwerken zu bedruckenden Bogen 2 mit bekannten Mitteln/ meist in geschuppter Form/ taktweise dem An¬ lagedruckwerk zugeführt. Die Taktfrequenz der Bogenförderung ist dabei von der Verarbeitungsgeschwindigkeit der Druckmaschine ab¬ hängig .On a feed table 1 of a printing machine, not shown, with at least one feed printing unit and possibly further printing units, the sheets 2 to be printed by the feed printing unit and, if appropriate, further printing units are fed to the feed printing unit in known manner / usually in scaled form / in cycles. The cycle frequency of the sheet conveyance is dependent on the processing speed of the printing press.
Die auf dem Anlegtisch 1 der Druckmaschine geförderten Bogen 2 werden vor Übergabe an das Anlagedruckwerk an quer zur Bogen- laufrichtung 3 angeordneten Anlegmarken 4 in Bogenlaufrichtung ausgerichtet (Fig. 1). Danach oder zeitgleich werden die Bogen 2 an einer seitlich am Anlegtisch 1 angeordneten Seitenmarke 5 quer zur Bogenlaufrichtung 3 ausgerichtet (Fig. 2). Die genann¬ ten Marken fungieren dabei als Anschläge.The sheets 2 conveyed on the feed table 1 of the printing press are aligned in the sheet travel direction at transfer marks 4 arranged transversely to the sheet running direction 3 before transfer to the feed printing unit (FIG. 1). Then or at the same time, the sheets 2 are aligned transversely to the sheet running direction 3 at a side mark 5 arranged on the side of the feed table 1 (FIG. 2). The brands mentioned act as stops.
Das Ausrichten erfolgt durch das Aufbringen einer Kraftkompo¬ nente auf den Bogen 2. Die Kraftkomponente beinhaltet eine Be¬ wegungskomponente 8 oder setzt sich aus einer Andrückkomponente 7 und einer Bewegungskomponente 8 zusammen (Fig. 3) . Vermittels der Kraftkomponente wird der auszurichtende Bogen 2 an die Anlegmarken 4 und/oder die Seitenmarke 5 angelegt und damit ausgerichtet. Das Anlegen des Bogens 2 erfolgt dabei durch das Aufbringen von intermittierenden/ d.h. zeitweilig aussetzenden Impulsen auf den Bogen. Unter Impuls wird die kurzzeitige Wirkung einer physika¬ lischen Größe verstanden/ Das Aufbringen der Impulse erfolgt mit einem Impulselement 6.Alignment is carried out by applying a force component to the sheet 2. The force component includes a movement component 8 or is composed of a pressure component 7 and a movement component 8 (FIG. 3). By means of the force component, the sheet 2 to be aligned is applied to the contact marks 4 and / or the side mark 5 and thus aligned. The sheet 2 is applied by applying intermittent / temporarily interrupting pulses to the sheet. The pulse is understood to mean the short-term effect of a physical quantity / the impulses are applied with a pulse element 6.
Dabei wird in der Wirkphase der Impulse eine Andrückkomponente 7 und eine Bewegungskomponente 8 oder nur eine Bewegungskomponente unter Schlupf auf den Bogen 2 aufgebracht. In der Nichtwirkphase der Impulse (Aussetzphase) erfolgt die kraftfreie Entspannung des Bogens. Der Schlupf kann durch die Veränderung der Größe der An¬ drückkomponente je nach Bedruckstoffart gewählt werden. Die Frequenz der intermittierenden Impulse ist wesentlich größer als die Taktfrequenz der geförderten Bogen. Die Taktfrequenz der geförderten Bogen liegt in der Größenordnung von mehreren Hertz (bis ca. 5 Hz) und die Frequenz der intermittierenden Impulse in der Größenordnung über 50 Hz/ vorzugsweise in der Größenordnung von 200 - 400 Hz.In the active phase of the impulses, a pressure component 7 and a movement component 8 or only one movement component with slip are applied to the sheet 2. In the non-active phase of the impulses (suspension phase) the force-free relaxation of the bow takes place. The slip can be selected by changing the size of the pressing component depending on the type of printing material. The frequency of the intermittent pulses is much higher than the clock frequency of the conveyed sheets. The cycle frequency of the conveyed sheets is in the order of several Hertz (up to approx. 5 Hz) and the frequency of the intermittent pulses in the order of more than 50 Hz / preferably in the order of 200-400 Hz.
Die Impulsfrequenz ist einstellbar bzw. in Relation zur Maschinen¬ geschwindigkeit steuerbar.The pulse frequency is adjustable or controllable in relation to the machine speed.
Die Bewegungskomponenten werden für jede Ausrichtrichtung getrennt phasengleich oder phasenversetzt auf den Bogen aufgebracht (Rich¬ tungspfeile in Fig. 2). Bei der phasenversetzten Ausrichtung ist ein unbeeinflußtes Ausrichten in Seiten- und Bogenförderrichtung möglich/ d.h. die seitliche Ausrichtung erfolgt unbeeinflußt von der Ausrichtung an den Anlegmarken und umgekehrt. Durch ein Auf¬ bringen der Bewegungskomponenten unter einem Winkel zur Bogenför- derrichtung (gestrichelte Pfeildarstellung in Fig. 2) ist es mög¬ lich/ den Bogen in beiden Ausrichtrichtungen mit einem einzigen Impulselement 6 auszurichten. Der Winkel ist einstellbar/ damit ist es möglich je nach Bedruckstoffart optimale Winkel auszuwäh¬ len und die Bewegungsrichtung des auszurichtenden Bogens (rechts oder links angeordneter Seitenanschlag 5) zu wählen. Die intermittierenden Impulse werden entweder rotativ oder trans- lativ aufgebracht. Das rotative Aufbringen ist beispielsweise mit einem mit hoher Frequenz umlaufenden rotativen Element 9 mit meh¬ reren zahnartigen Erhöhungen/ die den Bogen in der Wirkphase be¬ rühren/ möglich (Fig. 4). Das rotative Element 9 ist entweder pa¬ rallel oder senkrecht zur Bogenförderebene angeordnet. Bei der in Fig. 4 dargestellten Ausführungsform ist das rotative Element 9 in senkrechter Stellung unterhalb des Bogens 2 ange¬ ordnet; oberhalb des Bogens ist ein Abstützelement 10 angeordnet. Das rotative Element 9 drückt dabei den Bogen gegen das Abstütz¬ element 10. Bei Anordnung des rotativen Elementes oberhalb des Bogens fungierte der Anlegtisch 1 als Abstützelement. Das translative Aufbringen der Impulse ist beispielsweise mit einem Schwinganker (Fig. 5) oder einem Wagnerschen Hammer/ einem Vibrationselement oder einem Schwingungselement bzw. durch Trans¬ lation aus Rotation möglich. The movement components are applied to the sheet separately in phase or out of phase for each alignment direction (direction arrows in FIG. 2). With phase-shifted alignment, uninfluenced alignment in the side and sheet conveying direction is possible / ie the lateral alignment is unaffected by the alignment on the contact marks and vice versa. By applying the movement components at an angle to the sheet conveying direction (dashed arrow in FIG. 2), it is possible to align the sheet in both alignment directions with a single pulse element 6. The angle is adjustable / it is thus possible, depending on the type of substrate, to select the optimum angle and to choose the direction of movement of the sheet to be aligned (side stop 5 arranged on the right or left). The intermittent impulses are applied either rotatively or translatively. The rotary application is for example with a rotating element 9 rotating at high frequency with several tooth-like elevations / which touch the arc in the active phase / is possible (FIG. 4). The rotary element 9 is arranged either parallel or perpendicular to the sheet conveying plane. In the embodiment shown in FIG. 4, the rotary element 9 is arranged in a vertical position below the arch 2; A support element 10 is arranged above the arch. The rotary element 9 presses the sheet against the support element 10. When the rotary element is arranged above the sheet, the feed table 1 acted as a support element. The translative application of the impulses is possible, for example, with an oscillating anchor (FIG. 5) or a Wagnerian hammer / a vibrating element or an oscillating element or by translation from rotation.
