Die Erfindung betrifft eine Auslegevorrichtung an Bogenrotationsdruckmaschinen gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a delivery device on sheet-fed rotary printing machines according to the preamble of claim 1.
In Auslegevorrichtungen an Bogenrotationsdruckmaschinen sollen die Bogen mit einer praktisch auf Null reduzierten Geschwindigkeit zur Ablage auf einem Stapel kommen. In der Praxis bedeutet das, daß die Bogen auf einer kurzen Strecke abgebremst und dann auf den Stapel abgelegt werden müssen.In delivery devices on sheet-fed rotary printing machines, the sheets should be practically at zero can be placed on a stack at reduced speed. In practice this means that the Sheets have to be braked a short distance and then placed on the pile.
Zum Abbremsen der Bogen sind angetriebene Saugwalzen z. B. durch die US-PS 29 69 980 bekanntgeworden. To brake the sheet are driven suction rolls z. B. became known through US-PS 29 69 980.
Nachteilig bei dieser Saugwalze ist jedoch, daß sie ziemlich groß baut und so nicht nahe genug am Papierstapel angebracht werden kann.The disadvantage of this suction roll, however, is that it is quite large and not close enough to the Stack of paper can be attached.
Der Erfindung liegt die Aufgabe zugrunde, eine angetriebene Saugwalze für eine Auslegevorrichtung an einer Bogenrotationsdruckmaschine zu schaffen, mit der es möglich ist, den Abstand Saugwalzenmitte — Stapelkante möglichst klein zu halten; außerdem soll der abzubremsende Bogen während des Abbremsevorgangs über seine Breite ausgestreift, d.h. Falten geglättet werden.The invention is based on the object of a driven suction roll for a delivery device to create a sheet-fed rotary printing press with which it is possible to reduce the distance between the center of the suction roll and To keep the stacking edge as small as possible; in addition, the sheet to be braked should be during the braking process stripped across its width, i.e. wrinkles are smoothed.
Diese Aufgabe wird erfindungsgemäß durch den Gegenstand der kennzeichnenden Teile der Ansprüche gelöst.According to the invention, this object is achieved by the subject matter of the characterizing clauses of the claims solved.
Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, daß es möglich ist, während des Abbremsvorgangs den Bogen von der Bogenmitte nach außen nach beiden Seiten hin auszustreifen, und daß entsprechend der gerade zu verarbeitenden Bogenformatbreite ein Teil der Saugwalze inaktiv gestellt werden kann. Außerdem kann der Außendurchmesser der Saugwalze beliebig klein gehalten werden, und eine Saugluftzufuhr muß nicht von innen erfolgen.The advantages achieved by the invention are in particular that it is possible during the Braking the bow from the center of the bow to the outside to spread out to both sides, and that Depending on the sheet format width to be processed, part of the suction roll can be made inactive can. In addition, the outer diameter of the suction roll can be kept as small as desired, and a The suction air does not have to be supplied from the inside.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Es zeigt F i g. 1 einen Vertikalschnitt durch die Saugwalze,An embodiment of the invention is shown in the drawing and will be described in more detail below described. It shows F i g. 1 a vertical section through the suction roll,
F i g. 2 eine Ansicht von oben auf die Saugluftzufuhrstücke, F i g. 2 a view from above of the suction air supply pieces,
F i g. 3 eine Ansicht der Saugwalze.F i g. 3 is a view of the suction roll.
In nicht dargestellten Seitengestellen einer Bogenauslegevorrichtung ist in bekannter Weise eine angetriebene Saugwalze 1 gelagert. Sie kann, wie ebenfalls bekannt; in und entgegen Bogentransportrichtung Verschoben werden, um die Saugwalze 1 möglichst nahe — entsprechend dem Papierformat — an die hintere Stapelseite anzustellen. Die Saugwalze 1 ist als Vollkörper ausgeführt und mit einer Vielzahl von die Rotationsachse der Saugwalze 1 schneidenden Bohrungen 2 versehen. Sie haben z. B. einen Durchmesser von 4 mm. Die Bohrungen 2 liegen auf je einer von einer Walzenhälfte ausgehenden, links bzw. rechts steigenden Spirallinie um die Saugwalze 1. Die Bohrungen 2 sind jeweils um 10° am Umfang und ca. 6 mm seitlich zueinander versetzt angeordnet. Unterhalb der Saugwalze 1 sind über die gesamte, mit Bohrungen 2 versehene Länge der Saugwalze 1 eine Mehrzahl von gegeneinander abgeschotteten Saugluftzufuhrstücken 3 nebeneinander angeordnet. Die einzelnen Saugluftzufuhrstücke 3 sind an einen Radius »r« der Saugwalze 1 angepaßt und gegen die Umgebungsluft so abgedichtet, daß keine Fremdluft zwischen Saugwalze 1 und Saugluftzuführstücke 3 eintreten kann. Jedes Saugluftzufuhrstück 3 ist mittig mit einer Längsnut 4 versehen, die mit einem Anschlußrohr 6 in Verbindung steht. Über einen Schlauch 7 ist jedes der Anschlußrohre 6 mit einem ihm zugeordneten Absperrventil 8 verbunden. Sämtliche Absperrventile 8 sind über Schläuche bzw. Rohre an eine nicht dargestellte Saugluftquelle angeschlossen. In side frames, not shown, of a sheet delivery device, a driven suction roll 1 is mounted in a known manner. You can, as is also known; be moved in and against the sheet transport direction in order to place the suction roller 1 as close as possible - according to the paper format - to the rear side of the stack. The suction roll 1 is designed as a solid body and is provided with a large number of bores 2 which intersect the axis of rotation of the suction roll 1. You have e.g. B. a diameter of 4 mm. The bores 2 each lie on a spiral line starting from one roller half and rising to the left or right around the suction roller 1. The bores 2 are each arranged offset by 10 ° on the circumference and about 6 mm laterally to one another. Below the suction roll 1, over the entire length of the suction roll 1, which is provided with bores 2, a plurality of suction air supply pieces 3 which are sealed off from one another are arranged next to one another. The individual suction air supply pieces 3 are adapted to a radius "r" of the suction roll 1 and are sealed against the ambient air in such a way that no external air can enter between the suction roll 1 and suction air supply pieces 3. Each suction air supply piece 3 is provided in the middle with a longitudinal groove 4 which is connected to a connecting pipe 6. Each of the connecting pipes 6 is connected to a shut-off valve 8 assigned to it via a hose 7. All shut-off valves 8 are connected to a suction air source, not shown, via hoses or pipes.
Über die Absperrventile 8 kann die Saugluft jedes einzelnen Saugluftzufuhrstückes 3 eingestellt beziehungsweise abgestellt werden. Nahezu an die Saugwalze 1 anstoßend ist in entgegengesetzter Richtung zur Bogentransportrichtung ein Tisch 9 vorgesehen. Eine Oberfläche 11 des Tisches 9 ist etwas unterhalb des höchsten Punktes der Saugwalze 1 angeordnet. Der Tisch 9 ist auf seiner Oberfläche 11 mit Austrittsöffnungen 12 für Blasluft versehen. Die Austrittsöffnungen 12 sind dabei so gestaltet, daß sie den Luftstrom entlang der Oberfläche 11 austreten lassen, wodurch entsprechend dem »hydrodynamischen« Paradoxon der Papierbogen gegen den Tisch 9 gezogen wird.The suction air of each individual suction air supply piece 3 can be adjusted or adjusted via the shut-off valves 8 be turned off. Almost abutting the suction roll 1 is in the opposite direction to A table 9 is provided in the direction of sheet transport. A surface 11 of the table 9 is slightly below the arranged at the highest point of the suction roll 1. The table 9 is on its surface 11 with outlet openings 12 provided for blown air. The outlet openings 12 are designed so that they move along the air flow the surface 11 can emerge, whereby according to the "hydrodynamic" paradox of the paper sheet is pulled against the table 9.
Durch die spiralförmige Anordnung der Bohrungen 2 werden in Verbindung mit den Saugluftzufuhrstücken 3 nur wenige von ihnen gleichzeitig mit Saugluft beaufschlagt. Durch die Drehung der Saugwalze 1 werden die Bohrungen 2 in zeitlicher Reihenfolge an die Saugluftquelle an- bzw. von ihr abgeschaltet, und zwar jeweils beginnend von der Mitte der Saugwalze 1 nach ihrem rechten bzw. linken Ende hin. Durch diesen Effekt in Verbindung mit der Drehung der Saugwalze 1 in Bogenlaufrichtung wird ein seitlicher Ausstreifeffekt des abzubremsenden Bogens erzielt.The spiral arrangement of the bores 2 in connection with the suction air supply pieces 3 only a few of them have suction air applied at the same time. By rotating the suction roll 1 the bores 2 are switched on or off from the suction air source in chronological order, namely each beginning from the center of the suction roll 1 towards its right or left end. Because of this effect in connection with the rotation of the suction roll 1 in the sheet running direction, there is a lateral spreading effect achieved the arc to be braked.
