Description

BogenleiteinrichtungSheet guiding device

Die Erfindung betrifft eine Bogenleiteinrichtimg, die mittels einer Saugvorrichtung bogenförmige Bedruckstoffe während des Transportvorganges, insbesondere innerhalb von Druckmaschinen ansaugt und so in einer vorbestimmten Transportlage fixiert. Bekannt sind derartige Bogenleiteinrichtungen wie die nach der DE-OS 39 38 863 beschriebene Vorrichtung zum Führen frisch bedruckter Bogen, vorzugsweise in der Auslage von Druckmaschinen, bei der der Bogen mittels an Ketten umlaufender Greiferwagen gefördert wird.The invention relates to a sheet guiding device which, by means of a suction device, sucks in sheet-shaped printing materials during the transport process, in particular within printing machines, and thus fixes them in a predetermined transport position. Such sheet guiding devices are known, such as the device described in DE-OS 39 38 863 for guiding freshly printed sheets, preferably in the delivery of printing machines, in which the sheet is conveyed by means of gripper carriages rotating on chains.

Bei dieser Einrichtung wird die Unterseite des Bogens durch mittels Axial-Ventilatoren erzeugte Blasluftströme beaufschlagt. Dadurch wird der Bogen in gleichem Abstand von einer Führungsfläche flatter- und abschmierfrei geführt.With this device, the underside of the sheet is exposed to air currents generated by axial fans. This means that the sheet is guided at the same distance from a guide surface without fluttering or smearing.

Die insbesondere bei hohen Geschwindigkeiten und dünnem Druckträgermaterial häufig zum Flattern des Bogens kommende nachteilige Erscheinung wird durch diese Einrichtung beseitigt.This device eliminates the disadvantageous phenomenon of sheet fluttering, which often occurs, particularly at high speeds and with thin printing substrates.

Beschädigungen des Produktes, wie beispielsweise Kratzer, Knicke, etc., werden dadurch verhindert.This prevents damage to the product, such as scratches, creases, etc.

Mittels Einbau von Bogenleitblechen in Form einer Saugkastenkonstruktion wird der Bogen angesaugt und dem "Flattern" des Bedruckstoffes entgegengewirkt.By installing sheet guide plates in the form of a suction box construction, the sheet is sucked in and the "fluttering" of the printing material is counteracted.

Nachteilig an dieser Einrichtung ist jedoch, daß es bei einer Installation dises Bogenleitblecb.es gegenüber eines Strahlungstrockners zu einer überhöhten Erwärmung und damit zu einem Verzug des als Lochblech ausgebildeten Bogenleitbleches kommt. Die Aufgabe der Erfindung besteht deshalb darin, eine Bogenleiteinrichtimg zu schaffen, die wärmebedingte Verzüge der Bogenleiteinrichtungen und damit verbundene Qualitätsverluste der Druckprodukte verhindert.The disadvantage of this device, however, is that when this sheet guide plate is installed in contrast to a radiation dryer, excessive heating and thus distortion of the sheet guide plate, which is designed as a perforated plate, occurs. The object of the invention is therefore to create a sheet guide device that prevents heat-related distortion of the sheet guide devices and the associated loss of quality of the printed products.

Gelöst wird die Aufgabe durch die kennzeichnenden Merkmale der Ansprüche. Nachfolgend soll anhand eines Ausführungsbeispieles die erfindungsgemäße Einrichtung näher erläutert werden.
In der dargestellten Zeichnung zeigtThe object is achieved by the characterizing features of the claims. The device according to the invention will be explained in more detail below using an exemplary embodiment.

Transportfläche geschaffen, die keine Unebenheiten aufweist und dadurch Qualitätsbeeinflussungen der Druckprodukte ausschließt.A transport surface has been created that has no unevenness and therefore prevents any influence on the quality of the printed products.

Wird das Bogenleitblech 1 gegenüber einem Strahlungstrockner installiert, kommt es zu einer überhöhten Erwärmung und somit zu einem Verzug des Bogenleitbleches 1.If the sheet guide plate 1 is installed opposite a radiation dryer, excessive heating occurs and thus the sheet guide plate 1 becomes distorted.

Erfindungsgemäß wird dieser nachteiligen Erscheinung durch wasserleitende Kühlschlangen entgegengewirkt, die auf der Rückseite des Bogenleitbleches 1 wärmeleitend angeordnet sind.According to the invention, this disadvantageous phenomenon is counteracted by water-conducting cooling coils which are arranged in a heat-conducting manner on the back of the sheet guide plate 1.

Die Anordnung dieser Kühlschlangen erfolgt dabei so, daß die Luftein- und Luftaustrittsöffnungen 2 frei bleiben.The arrangement of these cooling coils is such that the air inlet and outlet openings 2 remain free.

Auf Grund der der durch den Strahler erzeugten unterschiedlichen Wärmeniveaus auf der den wärmeleitenden Kühlschlangen abgewandten Seite des Bogenleitbleches 1, kann es zu Ablösungen der Kontaktstellen zwischen Bogenleitblech 1 und den Kühlschlangen kommen und damit einen Verzug des des Bogenleitbleches 1 hervorrufen.Due to the different heat levels generated by the radiator on the side of the sheet guide plate 1 facing away from the heat-conducting cooling coils, the contact points between the sheet guide plate 1 and the cooling coils can become detached, thus causing the sheet guide plate 1 to become distorted.

Durch die erfindungsgemäße Einrichtung werden diese Nachteile verhindert.The device according to the invention prevents these disadvantages.

In der Figur 1 sind diese Kühlschlangen schematisch als Kühltaschen 3 dargestellt.In Figure 1, these cooling coils are shown schematically as cooling pockets 3.

Schematisch ist in dieser Figur auch diQ Anordnung eines Axialventilators 4 unterhalb der Rückwand 5 der Saugkastenkonstruktion dargestellt.This figure also schematically shows the arrangement of an axial fan 4 below the rear wall 5 of the suction box construction.

Die Unterseite und der schematische Schnitt der Saugkastenkonstruktion ist in Figur 2 abgebildet.The underside and the schematic section of the suction box construction is shown in Figure 2.

Das Bogenleitblech 1 und das Leitblech 6 des Kühlmittelleitsystemes sind als zwei deckungsgleich übereinander angeordnetenBleche mit einem gleichen Lochungsraster angeordnet.The sheet guide plate 1 and the guide plate 6 of the coolant guide system are arranged as two plates that are arranged one above the other and have the same hole pattern.

Dabei werden die beiden Bleche an den Luftein- und Luftaustrittsöffnungen (2) und an den Blechrändern mittels eines Laserschweißverfahrens bearbeitet.The two sheets are processed at the air inlet and outlet openings (2) and at the sheet edges using a laser welding process.

Das Bogenleitblech 1 und das Leitblech 6 weisen bei der Einrichtung unterschiedliche Dicken auf. Auf dem relativ gesehen dünnem Leitblech 6 sind Anschlußstutzen 8 angebracht, über die der Ein- und Austritt des Kühlmittels erfolgt.The sheet guide plate 1 and the guide plate 6 have different thicknesses in the device. Connecting pieces 8 are attached to the relatively thin guide plate 6, through which the coolant enters and exits.

Das Kühlmittel, vorzugsweise Wasser, wird durch die Kanäle 7 des Kühlmittelsystemes mittels eines Drucksystemes gedrückt und eine Wölbung des Leitbleches 6 bewirkt, die einen Hohlkörper analog zu den Schweißkonturen enstehen läßt. Das dickere Bogenleitblech 1 behält dabei seine ursprüngliche Form.The coolant, preferably water, is pressed through the channels 7 of the coolant system by means of a pressure system and causes the guide plate 6 to curve, which creates a hollow body analogous to the welding contours. The thicker sheet guide plate 1 retains its original shape.

Die Form der Kanalführungen können niäanderförmig, z-fönnig oder andere Grundstrukturen aufweisen.The shape of the channel guides can be nielloed, z-shaped or have other basic structures.
