Description
Zufuhr- oder Anlegetisch für Schnellpressen, Rotationsdruckmaschinen, Zweitourenmaschinen, Tiefdruck- und Gummidruckmaschinen sowie Falzmaschinen Die Erfindung bezweckt, bei gewöhnlichen Schnellpressen, bei Zweitourenmaschinen, Rotationsdruckmaschinen, Tiefdruck- und Gummidruckmaschinen sowie Falzmaschinen die Bogen über die Seitenziehvorrichtung hinweg sicher bis zu den Anlegemarken des Arbeitsz_v linders zu führen.Feed or feed table for high-speed presses, rotary printing machines, Two-turn machines, gravure and rubber printing machines as well as folding machines Die The purpose of the invention is for ordinary high-speed presses, for two-speed machines, rotary printing machines, Gravure and rubber printing machines as well as folding machines pull the sheets over the side pulling device away safely to the mooring marks of the Arbeitsz_vinder.
Da die Schnellpressen, Rotationsdruckmaschinen u. dgl. stündlich 4. 5oo Bogen und mehr bedrucken, müssen die Bogen mit sehr großer Geschwindigkeit über den Anlegetisch bewegt werden, so daß besonders bei dünnem Papier die Gefahr besteht, daß die vordere Bogenkante namentlich auf dem Wege über die Seitenziehvorrichtung vom Anlegetisch abgelüftet wird und somit der Bogen nicht ordnungsgemäß an den Anlegemarken des Druckzylinders ankommt. Bei der Ankunft an der Ziehvorrichtung verlassen nämlich die Bogen die aus umlaufenden Bändern und Gegendruckröllen bestehende Fördervorrichtung, so daß sie auf ihrem Wege über die Ziehvorrichtung keine Führung haben. Druckrollen oder andere mechanische Niederhaltvorrichtungen; die zudem nur eine schädliche Bremswirkung äußern könnten, lassen sich schlecht an dieser Stelle anbringen.Since the high-speed presses, rotary printing machines and the like every hour 4. To print 500 sheets and more, the sheets have to be passed over at a very high speed moving the feed table, so that especially with thin paper there is a risk of that the leading edge of the sheet is specifically on the way over the side pulling device is vented from the feed table and thus the sheet is not properly attached to the feed marks of the printing cylinder arrives. On arrival at the pulling device namely leave the sheets the conveyor device consisting of revolving belts and counter-pressure rollers, so that they have no guidance on their way over the pulling device. Pressure rollers or other mechanical hold-down devices; which also only has a harmful braking effect could not express themselves at this point.
Nach der Erfindung dient zum Niederhalten der Bogen im Bereich der Ziehvorrichtung Gebläsewind, der einem quer über den unteren Teil des Anlegetisches gelagerten Düsenrohr in der Förderrichtung der Bogen entströmt, so daß er fördernd wirkt und somit in der Lage ist, Bogen kleinerer Abmessung nach dem Verlassen der Fördervorrichtung über die Ziehvorrichtung bis zum Druckzylinder z u befördern.According to the invention is used to hold down the bow in the area Pulling device blower wind that runs across the lower part of the feed table stored nozzle tube flows out in the conveying direction of the sheet, so that it is conveying acts and is therefore able to bend smaller dimensions after leaving the Convey the conveying device via the pulling device to the printing cylinder.
Bei Schnellpressen ist Gebläsewind bereits zu dem Zweck verwendet worden, die Druckrollen zu ersetzen, wobei die Druckluftstrahlen senkrecht gegen die Förderbänder gerichtet werden.In the case of high-speed presses, blower wind is already used for this purpose been to replace the pressure rollers, with the compressed air jets perpendicular against the conveyor belts are straightened.
Auf der Zeichnung ist ein Ausführungsbeispiel der Erfindung veranschaulicht, und zwar stellen dar: Abb. i den Anlegetisch mit dem Druckzylinder und dem Bogenstapel mit Saugstange im Querschnitt, und Abb.2 eine Draufsicht auf das Düsenrohr: Durch die Sauger a der Saugerstange b werden die zu. bedruckenden Bogen vom Stapel d abgehoben und auf den Anlegetisch g gebracht, über den sie durch die üblichen Förderbänder i: bis zum Druckzylinder lz bewegt «-erden. Vor der Bogenziehvorrichtung h, durch die die Bogen seitlich ausgerichtet werden, nimmt die Förderung durch die Bänder t.' ihr Ende, so daß auch keine Gegendruckrollen zum Niederhalten des Bogens an dieser Stelle angebracht werden können. An deren Stelle tritt gemäß der Erfindung ein quer über den unteren Teildes Anlegetisches g angeordnetes Düsenrohr y, dessen Gebläsedüsen in der Förderrichtung der Bogen gegen die Ziehvorrichtung h geneigt gerichtet sind, so daß die Bogen bei rascher Förderung nicht ablüften können und durch den Gebläsestrahl gegen den Druckzylinder gefördert werden.An exemplary embodiment of the invention is illustrated in the drawing, namely show: Fig. i the feed table with the impression cylinder and the sheet pile with suction rod in cross section, and Fig. 2 a top view of the nozzle tube: Through the suction cups a of the suction rod b are the too. printing sheet lifted from the stack d and brought to the feed table g, over which it is carried by the usual conveyor belts i: moved up to the impression cylinder lz «- earth. Before the sheet puller h, through which the sheets are aligned laterally, the promotion by the belts takes t. ' their end, so that there are no counter-pressure rollers to hold down the sheet can be attached at this point. In their place occurs according to the invention a nozzle tube y arranged across the lower part of the feed table g, whose Fan nozzles inclined in the conveying direction of the sheet against the pulling device h are directed so that the sheets can not flash off at rapid promotion and be conveyed by the blower jet against the printing cylinder.
Das Düsenrohr p wird zur Regelung der Windstärke gegenüber der Anschlußstelle an die Gebläseleitung 7n vorteilhaft mit einem einstellbaren Abblasventil ia versehen, so daß keine zusätzliche Belastung des Gebläses eintritt,. wenn die Gebläsedüsen für geringe Windstärke durch entsprechende Einstellung des Ventiles ia umgestellt werden.The nozzle pipe p is used to regulate the wind force in relation to the connection point on the blower line 7n advantageously provided with an adjustable blow-off valve ia, so that there is no additional load on the fan. when the fan nozzles for low wind strength changed by setting the valve accordingly will.
Damit die Richtung der Gebläsestrahlen dem jeweils zu bedrückenden Bogen angepaßt werden kann, ist das Düsenrohr um seine Längsachse drehbar zu lagern.So that the direction of the blower jets is the one to be oppressed Arch can be adjusted, the nozzle tube is to be rotatably mounted about its longitudinal axis.
