Eine Saugwalze 01 besteht z. B. aus einem Hohizyiinder 02 mit in radialer Richtung verlaufenden Bohrungen 03. Der Hohizyiinder 02 ist auf einem seitengestellfesten, außen mit Lagermetall 04 versehenen Tragrohr 06 drehbar gelagert. Die Bohrungen 03 erstrecken sich etwa über die Hälfte, d. h. 150° bis 210°, insbesondere 180° bis 210° der Mantelfläche bzw. der Umfangslinie 07 der Saugwalze 01.A suction roller 01 consists, for. B. from a Hohizyiinder 02 with bores 03 running in the radial direction. The Hohizyiinder 02 is rotatably mounted on a support tube 06 which is fixed to the side frame and provided with bearing metal 04 on the outside. The bores 03 extend approximately over half, i. H. 150 ° to 210 °, in particular 180 ° to 210 ° of the lateral surface or the circumferential line 07 of the suction roll 01.
Das Tragrohr 06 sowie das Lagermetall 04 sind an ihrer oberen, d. h. einer bogennahen Seite mit Luftzufuhrschlitzen 08 versehen, so daß die durch das erste Ende des seitengestellfest gelagerten Tragrohres 06 zugeführte Saugluft zu den jeweiligen Bohrungen 03 des Hohizylinders 02 gelangen kann. Es entsteht bezüglich des Ansaugens ein wirksamer Teil der Mantelfläche 07 der Saugwalze 01 , etwa von 20 bis 30 Bogengrad.The support tube 06 and the bearing metal 04 are on their upper, d. H. Provide air supply slots 08 on a side near the bend, so that the suction air supplied through the first end of the support tube 06 which is fixedly mounted on the side frame can reach the respective bores 03 of the hollow cylinder 02. An effective part of the lateral surface 07 of the suction roller 01 is formed with respect to suction, for example from 20 to 30 degrees of arc.
Das Tragrohr 06 ist an seinem zweiten Ende mit einem Zapfen 09 versehen, auf welchem eine walzengelagerte Mitnehmerhülse 15 drehbar angeordnet ist, die drehfest mittels eines in radialer Richtung weisenden gekröpften Mitnehmerarmes 10 mit dem rotierbaren Hohizyiinder 02 verbunden ist. Die Mitnehmerhülse 15 ist mittels Wälzlagern 18; 19 auf dem Zapfen 09 bzw. in einem Seitengestell 17 in Wälzlagern 18; 19 gelagert. Auf der walzenabgewandten Seite des Seitengestells 17 ist ein mit der Mitnehmerhülse 15 verdrehfest verbundener Antriebsmotor 12, z. B. Schrittmotor oder ein winkellagegeregelter Elektromotor (d. h. Einzelantrieb) zur Erzeugung einer ungleichförmigen Geschwindigkeit in Umfangsrichtung aufgeflanscht.The support tube 06 is provided at its second end with a pin 09, on which a roller-mounted driver sleeve 15 is rotatably arranged, which is rotatably connected to the rotatable Hohizyiinder 02 by means of a crank arm 10 which points in the radial direction. The driving sleeve 15 is by means of roller bearings 18; 19 on the pin 09 or in a side frame 17 in roller bearings 18; 19 stored. On the side of the side frame 17 facing away from the roller, a drive motor 12, for. B. stepper motor or an angular position controlled electric motor (i.e. individual drive) flanged to produce a non-uniform speed in the circumferential direction.
Der Hohizyiinder 02 trägt in Uhrzeigerdrehrichtung A der Saugwalze 01 gesehen, am Anfang seiner eingebrachten Bohrungen 03 in axialer Richtung der Saugwalze 01 nebeneinander angeordnete, um einen Betrag b, z. B. drei bis fünf Millimeter, über die Umfangslinie 07 hinausragende Vordermarken 13.The Hohizyiinder 02 is seen in the clockwise direction of rotation A of the suction roller 01, on Beginning of his holes 03 arranged in the axial direction of the suction roller 01 next to each other by an amount b, z. B. three to five millimeters, over the circumferential line 07 protruding front marks 13th
Nach einer bevorzugten Ausführungsvariante weist der Hohizyiinder 02 mit Bohrungen 03 versehene Saugringe 14; 16 auf, die sich in axialer Richtung auf dem Hohizyiinder 02 beabstandet nebeneinander befinden. Die Saugringe 14; 16 sind jeweils durch auf dem Hohizyiinder 02 eingebrachte ringförmige Nuten 20 beabstandet. Es können auch noch weitere, nicht dargestellte Saugringe angeordnet sein. Jeder Saugring 14; 16 weist ebenfalls sich über die Hälfte der Umfangslinie 07 erstreckende Bohrungen 03 auf, die dann ebenfalls den Hohizyiinder 02 durchdringen.According to a preferred embodiment variant, the Hohizyiinder 02 has suction rings 14; 16, which are spaced apart in the axial direction on the Hohizyiinder 02. The suction rings 14; 16 are spaced apart by annular grooves 20 made on the Hohizyiinder 02. Further suction rings, not shown, can also be arranged. Each suction ring 14; 16 likewise has bores 03 which extend over half of the circumferential line 07 and which then likewise penetrate the Hohizyiinder 02.
Die Saugwalze 01 ist z. B. in einer Transportrichtung C eines Bogens gesehen am Ende eines Anlegetisches so angeordnet, daß ihre Mantelfläche oder Umfangslinie 07 geringfügig oberhalb der Tischebene befindlich ist.The suction roller 01 is e.g. B. seen in a transport direction C of a sheet at the end of a feed table so that its outer surface or circumferential line 07 is located slightly above the table level.
Falls die Saugwalze 01 - wie dargestellt - Saugringe 14; 16 aufweist, so ist für jeden der Saugringe 14; 16 im Anlegetisch ein separater Schlitz vorgesehen.If the suction roller 01 - as shown - suction rings 14; 16, so for each of the suction rings 14; 16 a separate slot is provided in the feed table.
In Transportrichtung gesehen hinter dem Anlegetisch ist eine Weiterbearbeitungsstation, z. B. eine Transportwalze oder ein Druckzylinder angeordnet, welcher den Bogen z. B. mittels Greifersystemen übernehmen kann.Seen in the transport direction behind the feed table is a further processing station, e.g. B. a transport roller or an impression cylinder, which the sheet z. B. can take over by means of gripper systems.
Die Funktionsweise der Saugwalze 01 ist wie folgt:The functioning of the suction roller 01 is as follows:
In Transportrichtung wird auf dem Anlegetisch durch bekannte Mittel ein bereits seitenkantenausgerichteter Bogen bis zu den Vordermarken 13 der stillstehenden Saugwalze 01 transportiert (Umfangsgeschwindigkeit gleich Null). Mittels des mit unterschiedlicher Drehzahl rotierbaren Antriebes über den Motor 12, die Mitnehmerhülse 15 und den Mitnehmerarm 10 wird der Hohizyiinder 02 mit einer Umfangsgeschwindigkeit von Null auf z. B. 0,7 m/s beschleunigt, so daß der Bogen auf einer geradlinigen Beschleunigungsstrecke und einer nachfolgenden Gleichlaufstrecke, die Umfangsgeschwindigkeit des Druckzylinders von z. B. 0,6 m/s erreicht und mittels Greifersystem bei einem vorbestimmten Greiferschließpunkt auf dem Druckzylinder festgehalten wird. Beim Transport eines Bogens 17 sind jeweils zumindest eine oder mehrere Bohrungen 03 der rotierenden Saugringe 14; 16 mit dem Luftzufuhrschlitz 08 des Tragrohres 06 in Verbindung, so daß ein Bewegen des Bogens in Transportrichtung erfolgen kann. Die Umfangsgeschwindigkeit pendelt somit bei einer Umdrehung der Saugwalze 01 zwischen Null und dem 1 ,3- bis 2,5-fachen der Umfangsgeschwindigkeit des Druckzyiinders.In the transport direction, a sheet that is already aligned on the side edges is transported on the feed table to the front marks 13 of the stationary suction roller 01 (peripheral speed equal to zero) by known means. By means of the drive, which can be rotated at different speeds, via the motor 12, the driving sleeve 15 and the driving arm 10, the Hohizyiinder 02 becomes at a peripheral speed from zero to z. B. accelerated 0.7 m / s , so that the arc on a linear acceleration path and a subsequent synchronous path, the peripheral speed of the printing cylinder of z. B. 0.6 m / s and is held by means of a gripper system at a predetermined gripper closing point on the pressure cylinder. When transporting a sheet 17, at least one or more bores 03 of the rotating suction rings 14; 16 with the air supply slot 08 of the support tube 06 in connection so that the sheet can be moved in the transport direction. The circumferential speed thus fluctuates between zero and 1.3 to 2.5 times the circumferential speed of the printing cylinder when the suction roll 01 rotates.
Die Transportgeschwindigkeit des Bogens kann geringfügig (z. B. 10%) größer als die Umfangsgeschwindigkeit eines nachfolgenden Transportmittels, z. B. Zylinders, sein. Dieses nachfolgende Transportmittel kann wiederum Vordermarken aufweisen, so daß eine nochmalige Ausrichtung erfolgt. The transport speed of the sheet can be slightly (z. B. 10%) greater than the peripheral speed of a subsequent means of transport, e.g. B. cylinders. This subsequent means of transport can in turn have front marks so that it is aligned again.
