Description
jeweils für die erneute Bildung eines Vakuums erforderlich ist.is required in each case for the renewed formation of a vacuum.
In der Zeichnung ist eine nach der Erfindung ausgebildete Vorrichtung in Seitenansicht schematisch dargestellt.In the drawing, a device designed according to the invention is shown schematically in side view shown.
Auf Förderbändern 6 laufen die Bogen 1 und 2 mit einem gewissen Abstand voneinander. Die Bogen werden mittels einer Schneidevorrichtung 7 vom Rollenpapier getrennt.The sheets 1 and 2 run on conveyor belts 6 at a certain distance from one another. The sheets are separated from the roll paper by means of a cutting device 7.
Sobald der hintere Rand des Bogens2 die in der Zeichnung dargestellte Lage erreicht hat, in welcher er von der Fördervorrichtung 4,6 freigegeben ist, schlägt die um die Achse 12 schwenkbare Hubvorrichtung 3 nach oben. Hierbei treten die Arme dieser Hubvorrichtung zwischen den Förderbändern 6 hindurch und bringen den hinteren Bogenrand zum Anhaften gegen die Teller der Sauger 5, welche lediglich eine durch einen Doppelpfeil angegebene Hin- und Herbewegung ausführen.As soon as the trailing edge of sheet2 is in the Has reached the position shown in the drawing, in which it is released by the conveyor 4, 6, strikes the pivotable lifting device 3 about the axis 12 upwards. Here kick the arms of this Lifting device between the conveyor belts 6 and bring the rear edge of the sheet to adhere against the plates of the suction cups 5, which only have a backward movement indicated by a double arrow and perform float.
Schon im Augenblick des Anhaftens des hinteren Bogenrandes schwenkt die Hubvorrichtung 3 zurück, wobei das freie Ende 9 etwa auf halbem Weg der abwärts gerichteten Schwenkbewegung durch die Forderbänder 6 nach unten zurücktritt, so daß schon die Vorderkante des folgenden Bogensl unter den angehobenen hinteren Rand des Bogens2 eingeschoben werden kann.The lifting device 3 swivels back as soon as the rear edge of the sheet sticks, the free end 9 about halfway through the downward pivoting movement Conveyor belts 6 back down so that the leading edge of the following sheet under the raised rear edge of the sheet2 can be inserted.
Die Arme der Hubvorrichtung 3 weisen eine Kröpfung 10 auf, welche in der gestrichelt gezeichneten oberen Lage der Hubvorrichtung vor dem vorderen Ende 11 der Fördermittel 4 liegt.The arms of the lifting device 3 have a crank 10, which is shown in dashed lines upper position of the lifting device is in front of the front end 11 of the conveyor 4.
Die Schwenkbewegung der Hubvorrichtung 3 wird von einer Nockenscheibe 13 gesteuert, die auf einer mit der Welle der Schneidevorrichtung 7 gekoppelten Welle sitzt. Gegebenenfalls ist eine Untersetzung in die Antriebsverbindung 8 eingeschaltet. Die Nockenscheibe 13 wirkt auf das Hebelgestänge 14, 15. 16 ein.The pivoting movement of the lifting device 3 is controlled by a cam disk 13, which is on a with the shaft of the cutting device 7 coupled shaft sits. If necessary, a reduction in the drive connection 8 switched on. The cam disk 13 acts on the lever linkage 14, 15, 16 a.
