Description
Vorrichtung zur Herstellung von Wellpappe aus mehreren Bahnen Die Erfindung betrifft eine Vorrichtung zur Herstellung sich rechtwinklig kreuzender Wellbahnen aus beliebigem Werkstoff, z. B. Pappe, Hartpappe, Leder usw.Device for the production of corrugated cardboard from several webs Die The invention relates to a device for producing at right angles intersecting Corrugated sheets made of any material, e.g. B. cardboard, hard cardboard, leather, etc.
Es ist an sich bekannt, auf eine Wellpappbahn Tafeln mit zu den Rippen der Bahn senkrecht stehenden Rippen aufzubringen. Dies wurde jedoch bisher ausschließlich von Hand bzw. mit ungenügenden technischen Hilfsmitteln ausgeführt, wodurch das Fertigfabrikat wesentlich verteuert wurde.It is known per se to place panels on a sheet of corrugated cardboard with the ribs to apply vertical ribs to the web. However, so far this has been exclusively carried out by hand or with insufficient technical aids, whereby the The finished product became much more expensive.
Das Wesen der vorliegenden Erfindung besteht nun darin, daß auf eine mit Querrillen versehene Wellpappbahn abgeschnittene Stücke einer rechtwinklig zur Bahn verlaufenden zweiten Wellpappbahn durch eine oder mehrere Saugvorrichtungen, die wechselseitig den Transport der Stücke vornehmen, pneumatisch aufgebracht werden, wie solches an sich bei Druck- und anderen Papier verarbeitenden Maschinen bekannt ist.The essence of the present invention is that on a corrugated cardboard sheet provided with transverse grooves cut pieces of a perpendicular to the Second corrugated cardboard web running through one or more suction devices, which alternately carry out the transport of the pieces, are applied pneumatically, as is known per se in printing and other paper processing machines is.
Wichtig für die vorliegende Erfindung ist ferner, daß die Erzeugung des Unterdruckes in den Saugvorrichtungen in Zylindern erfolgt, an deren Enden Toträume angeordnet sind, die eine vertikale Bewegung im Sinne der Kolbenbewegung ausüben, gegenüber der Kolbenbewegung jedoch nacheilen.It is also important for the present invention that the generation of the negative pressure in the suction devices takes place in cylinders, at the ends of which there are dead spaces are arranged that exercise a vertical movement in the sense of the piston movement, however lag behind the piston movement.
In der Zeichnung ist der Erfindungsgegenstand in einer Ausführungsform beispielsweise schematisch dargestellt, und zwar zeigt Abb. z eine Draufsicht, Abb.2 eine Seitenansicht, Abb. 3 den Grundriß eines Teiles der pneumatischen Fördereinrichtungen. Von den Walzen a wird die Papierbahn b in bekannter Weise geriffelt. Rechtwinklig zu der Bahn b wird eine weitere, ebenfalls geriffelte Bahn d angeordnet, die durch eine Schneidvorrichtung r zu Tafeln f geschnitten wird. Diese Tafeln f werden mittels einer pneumatischen Fördereinrichtung aufgenommen und auf die Bahn b aufgesetzt.In the drawing, the subject matter of the invention is shown schematically in one embodiment, for example, namely Fig. Z shows a plan view, Fig.2 shows a side view, Fig. 3 shows the plan of part of the pneumatic conveying devices. The paper web b is corrugated by the rollers a in a known manner. At right angles to the web b, a further, also corrugated web d is arranged, which is cut into sheets f by a cutting device r. These panels f are picked up by means of a pneumatic conveyor device and placed on the web b.
Die pneumatische Fördereinrichtung besteht aus mehreren Kolben o nebst den zugehörigen Zylindern u: Durch eine Kurbelwelle i, eine Pleuelstange k, einen Balancier l und eine Schubstange m werden die Kolben o in Gleitbahnen t hin und her bewegt. Die Weglänge der Saugvorrichtungen ist so lang, daß die auf der Rollbahn s befindliche Tafel f 2rfaßt und der Bahn b bündig deckend zugeführt werden kann. Die Luftzutritt- bzw. -austrittöffnungen v in den Zylindern yi sind so angeordnet, daß am Ende der Zylinder n Toträume p, q entstehen. Der Hub der Kurbelwelle i wird so groß gewählt, daß der Kolben beim Hingang im Zylinderinnern Unterdruck erzeugt.The pneumatic conveying device consists of several pistons o together with the associated cylinders u: The pistons o are moved back and forth in slideways t by a crankshaft i, a connecting rod k, a balancer l and a push rod m. The path of the suction devices is so long that the board located on the runway s can be grasped and fed flush with the web. The air inlet and outlet openings v in the cylinders yi are arranged so that n dead spaces p, q arise at the end of the cylinder. The stroke of the crankshaft i is chosen to be so large that the piston generates negative pressure in the interior of the cylinder when it enters.
Der Sauger g zum Anheben der Barunterliegenden Tafel f steht mittels der Leitung v mit dem Zylinder n in Verbindung. Beim Weitergang des Kolbens o trifft dieser schließlich auf den Totraum q und nimmt nunmehr den Sauger g mit.The suction cup g for lifting the panel f underneath the bar is connected to the cylinder n by means of the line v. As the piston o continues, it finally encounters the dead space q and now takes the suction cup g with it.
Beim Rückwärtsgang des Kolbens wird die Luft im Zylinder n verdichtet und der von dem Sauger g gehaltene Bogen auf die Barunterliegende Bahn abgestoßen.When the piston moves backwards, the air in cylinder n is compressed and repelling the sheet held by the sucker g onto the web underlying the bar.
Durch Anwendung mehrerer Saugheber, die beispielsweise wechselweise zueinander arbeiten, wird erreicht, daß eine Serie derselben die Tafeln f fördert, während die andere Serie zurückläuft. Hierdurch wird ein nahezu kontinuierlicher Betrieb erreicht.By using several suction cups, the example work alternately to one another, it is achieved that a series of these work the tables f promotes while the other series runs back. This makes an almost continuous one Operation achieved.
Die Bahn b wird vor der Aufbringung der Tafeln f in an sich bekannter Weise mit einer Leimschicht versehen, damit die aufgebrach-An Tafeln f söfort nach dem Aufbringen fest auf der Bahn b haftenbleiben.The web b is known per se before the panels f in Provided with a layer of glue so that the panels can be opened immediately adhere firmly to the web b after application.
