Querschneidemaschinen für Papier, Pappe, Karton, Stoffe u. dgl. mit einem umlaufenden Obermesser arbeiten in der Regel derart, daß die Messerwelle ständig gedreht wird. Hierbei ist aber folgender Nachteil zu verzeichnen. Das Schneidgut bewegt sich bekanntlich in stets gleichem Tempo vorwärts, und es wird jeweils so viel abgeschnitten, als während eines Messerkreisens durchgelaufenCross cutting machines for paper, cardboard, cardboard, fabrics and the like with a rotating Upper knives usually work in such a way that the knife shaft is constantly rotated. However, this has the following disadvantage record. As is well known, the food to be cut moves forward at the same pace, and as much is cut off in each case as is run through during a knife circle
ίο ist. Die Schneidlänge wurde also von der Umdrehungsdauer des Messers bestimmt, und deshalb war sie beschränkt. Zwar könnte ja diese Dauer durch eine entsprechende Übersetzung beliebig vergrößert werden, das aber ist in der Praxis nicht verwendbar, weil dann die Messerbewegung zu langsam wird, um ein kräftiges Schneiden zu ermöglichen.ίο is. The cutting length was therefore determined by the The rotation time of the knife was determined, and therefore it was limited. Yes, it could this duration can be increased as required by a corresponding translation, but that cannot be used in practice because the knife movement will then be too slow to allow a enable powerful cutting.
Bei der neuen Einrichtung soll dieser Nachteil dadurch beseitigt werden, daß das Messer nur absatzweise bewegt wird. Durch die hierbei jedesmal erfolgende schnelle Bewegung des Messers wird ein sauberer, rechtwinkliger Schnitt und eine größere Durchschlagskraft des Messers erreicht, auch fällt das Stauchen des nachfolgenden Schneidgutes am umlaufenden Messerbalken weg. Es können infolgedessen auch die denkbar größten Schneidlängen erzielt werden. Aber auch geringere Längen bleiben möglich, da es lediglich notwendig ist, die Ruhepause für das Messer entsprechend abzugrenzen.In the new device, this disadvantage is to be eliminated in that the knife is only moved intermittently. Because of the rapid movement that takes place every time of the knife becomes a cleaner, square cut and greater penetration of the knife reached, also the upsetting of the following material to be cut falls on the circumferential Knife bar gone. As a result, the longest possible cutting lengths can also be used be achieved. But shorter lengths are also possible, since it is only necessary is to delimit the break for the knife accordingly.
In der Zeichnung ist eine beispielsweise Ausführungsform der Erfindung schematisch dargestellt.An example embodiment of the invention is shown schematically in the drawing shown.
Über den Tisch α wird das (hier nicht dargestellte) Schneidgut von den Transportwalzen b ständig in der Pfeilrichtung zugeführt. Das Untermesser c ist am Vorderrand der . Laufbahn befestigt; das Obermesser d sitzt auf einer Welle e, und diese Welle trägt fest angeordnet an dem Ende ein Zahnrad f sowie vor ihm eine Platte g mit einer kreisförmigen Ausbuchtung g1. Mit h ist die Antriebsscheibe bezeichnet; an ihrem Umfange ist eine Zahnleiste i aufgesetzt, welche mit den Zähnen f in Eingriff steht, und an ihrer Vorderfläche trägt sie einen ausgeschnittenen Ring k. Via the table α , the material to be cut (not shown here) is continuously fed in the direction of the arrow by the transport rollers b. The lower knife c is on the front edge of the. Track attached; the upper knife d is seated on a shaft e, and this shaft carries a gear wheel f , which is fixedly arranged at the end, and a plate g with a circular bulge g 1 in front of it. The drive pulley is denoted by h; A toothed strip i is placed on its circumference, which meshes with the teeth f , and on its front surface it has a cut-out ring k.
Die gezeichnete Stellung ist die Schneidstellung. Nach dem Schneiden dreht das Messer bis zum Ende der Zahnleiste weiter, wonach es außer Eingriff kommt. Gleichzeitig ist die Platte g gedreht worden, und deren kreisförmige Ausbuchtung kommt mit dem Ring k in Eingriff, wodurch während des ganzen Vorbeigleitens des Ringes ein Zurückfallen des Messers verhindert wird. Am Ende des Ringes wird der Eingriff von Ring k und Platte g unterbrochen, und die Zahnleiste i greift wieder in die Zahnung f ein, wodurch die Welle e und damit das Messer eine neue Drehung ausführt.The position shown is the cutting position. After cutting, the knife continues to rotate until the end of the toothed strip, after which it disengages. At the same time, the plate g has been rotated and its circular bulge comes into engagement with the ring k , whereby the knife is prevented from falling back during the entire passage of the ring. At the end of the ring, the engagement of ring k and plate g is interrupted, and the toothed bar i again engages in the toothing f, as a result of which the shaft e and thus the knife rotates again.
