Description

Die Erfindung bezieht sich auf eine Bogenleitvorrichtung mit einem gekühlten Bogenleitblech nach dem Oberbegriff des Patentanspruches 1 zur Verwendung in Bogendruckmaschinen.The invention relates to a sheet guide device with a cooled sheet guide plate according to the preamble of claim 1 for use in sheet printing machines.

Bekannt ist eine solche Bogenleitvorrichtung aus DE 94 18 358 U1. Die durch diese Druckschrift offenbarte Bogenleitvorrichtung besteht aus einem gelochten Bogenleitblech, einer darunter angeordneten Luftkammer und einem darin unmittelbar unter dem Bogenleitblech ausgebildeten Kühlsystem mit von Wasser durchströmten Kühlkanälen. Letztere sind als oben offene Rinnen aus Blech geformt und mit der Rückseite (Unterseite) des Bogenleitbleches verschweißt. Ihre Anordnung erfolgt in der weise, daß Luftöffnungen im Bogenleitblech nicht verdeckt werden, so daß Blasluft aus der Luftkammer durch die Luftöffnungen unter den über das Bogenleitblech hinweg transportierten Bogen austreten und gegebenenfalls auch angesaugt werden kann.Such a sheet guiding device is known from DE 94 18 358 U1. The sheet guiding device disclosed by this document consists of a perforated sheet guiding plate, an air chamber arranged underneath and a cooling system formed therein directly under the sheet guiding plate with cooling channels through which water flows. The latter are made of sheet metal and are welded to the back (underside) of the sheet guide plate. They are arranged in such a way that air openings in the sheet guide plate are not covered, so that blown air can escape from the air chamber through the air openings under the sheet transported over the sheet guide plate and, if appropriate, can also be sucked in.

Verlangt wird von Bogenleitvorrichtungen der von der Erfindung betroffenen Bauart eine möglichst gleichmäßig und optimal gekühlte Bogenleitfläche und eine auch unter wechselnden Temperaturen dichte Trennung des Kühlmittels von der Luft in der Luftkammer. Das Bogenleitblech soll eine glatte Oberfläche aufweisen und darf bei sich ändernden Temperaturen nicht zu Verwerfungen neigen. Andererseits soll die Bogenleitvorrichtung eine möglichst geringe Bauhöhe und ein geringes Gewicht aufweisen, leicht montierbar und mit möglichst geringem Aufwand herstellbar sein.What is required of sheet guiding devices of the type affected by the invention is a sheet guiding surface that is cooled as uniformly and optimally as possible and a separation of the coolant from the air in the air chamber that is sealed even under changing temperatures. The sheet guide plate should have a smooth surface and should not tend to warp when the temperature changes. On the other hand, the sheet guiding device should have the lowest possible height and weight, be easy to assemble and be able to be produced with as little effort as possible.

Es ist Aufgabe der Erfindung, eine Bogenleitvorrichtung der eingangs genannten Bauart mit geringer Bauhöhe kostengünstig herzustellen, bei der eine glatte Bogenleitfläche auch im praktischen Betrieb erhalten bleibt und gleichmäßig gekühlt werden kann, um eine hohe Betriebssicherheit im schnellen Fortdruck hochtouriger Maschinen zu erreichen.It is an object of the invention to produce a sheet guiding device of the type mentioned at the outset with a low overall height, in which a smooth sheet guiding surface also in practical operation is maintained and can be cooled evenly in order to achieve high operational reliability in the fast production of high-speed machines.

Zur Lösung dieser Aufgabe besteht die Erfindung in einer Bogenleitvorrichtung der eingangs genannten Bauart mit Ausbildungsmerkmalen nach dem Kennzeichen des Patentanspruches 1.To achieve this object, the invention consists in a sheet guiding device of the type mentioned at the outset with training features according to the characterizing part of patent claim 1.

Herausragend ist das Merkmal der Anordnung eines Dichtungsmittels zwischen dem Kühlmittel und der Luft in der Luftkammer in Verbindung mit der dadurch ermöglichten Punktschweißung oder Impulsschweißung (Kondensatorentladungsschweißen) zur Sicherung einer ausreichend festen Verbindung zwischen dem eigentlichen Bogenleitblech und dem Kühlwannenblech, in dem die Kanäle für das Kühlmittel ausgebildet sind. Vorzugsweise kommt als Dichtungsmittel ein Weichgummiring zur Anwendung, insbesondere ein sogenannter O-Ring mit geringer Shorehärte. Wärmeeinwirkungen durch die Schweißung werden somit äußerst gering gehalten und wirken sich in keiner Weise auf die den Bogen führende Oberfläche des Bogenleitbleches aus. Zur Verringerung der Herstellungskosten werden vorgefertigte O-Ringe in Rillen eingelegt, die in das Kühlwannenblech eingedrückt sind, worauf eine punktförmige Schweißung entweder auf einer Seite neben dem eingelegten Dichtungsring oder vorzugsweise auf beiden Seiten neben dem eingelegten Dichtungsring erfolgt. Dazu weist ein im Bereich der Luftöffnungen des Bogenleitbleches mit Ausschnitten versehenes Kühlwannenblech Prägungen mit einer den Ausschnitt umschließenden Rille für die Aufnahme eines Dichtungsringes und beidseitig daneben flach und bündig an dem Bogenleitblech anliegende Schweißzonen auf. Die konstruktive Ausbildung der Erfindungsmerkmale ermöglicht eine gleichmäßig und optimal gekühlte Bogenleitfläche, wobei auch unter wechselnden Temperaturen eine dichte Trennung des Kühlmittels von der Luft in der Luftkammer erhalten bleibt. Die im Wege der Punktschweißung, Laserschweißung oder Impulsschweißung (Kondensatorentladungsschweißen) hergestellte Verbindung zwischen dem Bogenleitblech und dem Kühlwannenblech führt weder bei der Herstellung der Bogenleitvorrichtung noch bei deren bestimmungsgemäßen Verwendung unter wechselnden Temperaturen zu unerwünschten Verwerfungen.Outstanding is the feature of the arrangement of a sealant between the coolant and the air in the air chamber in connection with the spot welding or pulse welding (capacitor discharge welding) thereby enabled to ensure a sufficiently firm connection between the actual arc guide plate and the cooling trough plate, in which the channels for the coolant are trained. A soft rubber ring is preferably used as the sealant, in particular a so-called O-ring with low Shore hardness. The effects of heat from the welding are thus kept extremely low and have no effect on the surface of the sheet guide plate that guides the sheet. To reduce manufacturing costs, prefabricated O-rings are inserted into grooves that are pressed into the cooling trough plate, whereupon spot welding is carried out either on one side next to the inserted sealing ring or preferably on both sides next to the inserted sealing ring. For this purpose, a cooling trough plate provided with cutouts in the area of the air openings of the sheet guide plate has embossments with a groove enclosing the cutout for receiving a sealing ring and, on both sides, flats lying flush and flush against the sheet guide plate. The constructive design of the features of the invention enables a uniformly and optimally cooled sheet guiding surface, and even under changing temperatures a tight separation of the coolant from the Air remains in the air chamber. The connection between the arc guide plate and the cooling trough plate, which is produced by means of spot welding, laser welding or pulse welding (capacitor discharge welding), does not lead to undesirable distortions during the manufacture of the arc guide device or when used as intended under changing temperatures.

Zur Abdichtung des Kühlmittels in den Kanälen des Kühlmittelsystems 4 gegenüber der Luft in der Luftkammer 5 ist ein Dichtungsmittel vorgesehen. Dieses Dichtungsmittel besteht im dargestellten Falle aus einer Weichgummischnur oder vorzugsweise einem Weichgummiring 8, welcher in eine rillenförmige Prägung 9 des Kühlwannenbleches 3 eingebracht ist. Im Falle des Beispieles nach Figur 2 befindet sich einseitig neben der Prägung 9 mit dem eingelegten Dichtungsring 8 eine flach und bündig an dem Bogenleitblech anliegende Schweißzone 10. Im Falle des Beispieles nach den Figuren 3 und 4 ist eine solche Schweißzone 10 beidseitig neben der rillenförmigen Prägung 9 mit dem darin eingebrachten Dichtungsring 8 vorgesehen. In den einseitig oder beidseitig angeordneten Schweißzonen sind das Bogenleitblech 1 und das Kühlwannenblech 3 durch in Abständen vorgenommene Punktschweißungen 11 miteinander verbunden. Die Luftkammer 5 ist in nicht dargestellter weise mit dem Luftversorgungssystem der Maschine verbunden und kann sowohl mit überdruck als auch mit Unterdruck beaufschlagt werden.In the sheet guide device, a sheet guide plate 1 forms with its surface the sheet guide surface 2 for the sheet transported over the sheet guide device. On the underside opposite the sheet guide surface 2, a cooling trough plate 3 is connected to the sheet guide plate 1, in which a cooling system 4 with coolant channels is formed. The cooling system is located within an air chamber 5, which is formed by a further sheet 6. Between the channels of the coolant system 4 are in the sheet guide plate 1 Air openings 7 are provided, which in the case of the example are formed by tongue-shaped incisions and can be blown through the air from the air chamber 5 under the sheet, not shown in the drawing, which is transported over the sheet guide surface 2. A sealant is provided to seal the coolant in the channels of the coolant system 4 from the air in the air chamber 5. In the case shown, this sealing means consists of a soft rubber cord or preferably a soft rubber ring 8, which is introduced into a groove-shaped embossing 9 of the cooling trough plate 3. In the case of the example according to FIG. 2 there is a welding zone 10 on one side next to the embossment 9 with the inserted sealing ring 8. In the case of the example according to FIGS. 3 and 4, such a welding zone 10 is located on both sides next to the groove-shaped embossing 9 provided with the sealing ring 8 inserted therein. In the welding zones arranged on one or both sides, the sheet guide plate 1 and the cooling trough plate 3 are connected to one another by spot welds 11 which are carried out at intervals. The air chamber 5 is connected in a manner not shown to the air supply system of the machine and can be pressurized with both overpressure and underpressure.
