Description
Verfahren und Vorrichtung zum Abziehen von Papierbeuteln o. dgl. vom Stempel eines Ziehschachtes Es ist bekannt, konische Werkstücke, wie z. B. Papiertrinkbecher, die ,auf dem.entsprechend gestalteten Formstempel mit Hilfeeines Gegenstempels durch Ziehen oder Pressen hergestellt werden, oder auch konische Verpackungsbehälter, die auf einem entsprechenden Formklotz durch Faltfinger, Faltklappen o. dgl. erzeugt werden, von dem konischen Formstempel bzw. konischen Formklotz, auf dem sie mit verhältnismäßig großer Reibung festsitzen, mittels Luftstromes vom Formstempel abzustreifen. Ferner ist es bekannt, auf einem zylindrischen Dorn hergestellte Papierbeutel durch Druckluft vom Dorn abzustreifen.Method and apparatus for pulling paper bags o. The like. From Stamp of a drawing shaft It is known to use conical workpieces such. B. paper drinking cups, the, on the correspondingly designed form stamp with the help of a counter stamp Drawing or pressing, or also conical packaging containers, generated on a corresponding form block by folding fingers, folding flaps or the like be, of the conical die or conical form block on which they are with stuck relatively high friction, wiping off the forming die by means of an air stream. It is also known to use paper bags made on a cylindrical mandrel Stripping compressed air from the mandrel.
Demgegenüber handelt es sich bei der Erfindung um ein Verfahren zum Abziehen von Papierbeuteln o. dgl. vom Stempel oder Formklotz eines Ziehschachtes. Die Erfindung besteht darin, daß der letzte Teil des Arbeitsweges des Werkstückes im Ziehschacht unter Einfluß von Druckluft erfolgt, indem nach der Formgebung des Werkstückes Saug- oder Druckluft in Wirksamkeit tritt, so daß - das Ausstoßen aus dem Schacht nicht mehr durch den Stempel selbst zu erfolgen braucht. Auf diese Weise gelingt es, die Arbeitszeit abzukürzen, den Stempelhub zu verringern und alle mechanischen Mittel, wie gesteuerte Abstreifer o. dgl., zu ersparen.In contrast, the invention is a method for Removal of paper bags or the like from the stamp or shaped block of a drawing shaft. The invention consists in that the last part of the work path of the workpiece takes place in the drawing shaft under the influence of compressed air by after the shaping of the Workpiece suction or compressed air comes into effect, so that - the ejection from the shaft no longer needs to be done by the stamp itself. In this way it is possible to shorten the working time, to reduce the punch stroke and all mechanical Means, such as controlled scrapers or the like. To save.
Man kann in an .sich bekannter Weise Druckluft in das Innere des Ziehstempels hineinleiten und sie so steuern, daß sie während des Heraustretens des Beutels aus dem Ziehschacht wirksam wird.Compressed air can be introduced into the interior of the drawing punch in a manner known per se lead in and control them so that they come out during the exit of the bag the draw shaft takes effect.
Man kann aber auch die Stirnflächen des den Beutel tragenden Ziehstempels mit der Mündung in der Vorschubrichtung des Stempels derart hin und her bewegten Saugdüsen zusammentreten lassen, daß die Saugdüse vermöge einer Relativbewegung in bezug auf den Ziehstempel zwecks Verkürzung des Stempelhubes den Beutel abzieht. But you can also let the end faces of the drawing punch carrying the bag come together with the mouth in the direction of advance of the punch suction nozzles moved back and forth in such a way that the suction nozzle pulls off the bag by virtue of a relative movement with respect to the drawing punch in order to shorten the punch stroke.
Hier wird darauf hingewiesen, daß bereits eine Vorrichtung bekanntgeworden ist, bei der der Ziehschachtmündung eine Saugdüse ortsfest zugeordnet ist, die derart absatzweise arbeitet, daß die von ihr angesaugten Werkstücke in den Pausen durch mechanische Mittel abgeführt werden können. Bei der bekannten Einrichtung muß aber der Stempelhub so groß sein, daß das Werkstück- vom Stempel selbst vollkommen durch den Ziehschacht hindurchgetrieben wird. Eine Arbeitshubverkürzung des Ziehstempels wird also durch die bekannte - Einrichtung nicht erreicht.It is pointed out here that a device has already become known is, in which a suction nozzle is fixedly assigned to the mouth of the drawing shaft, which in such a way works intermittently that the workpieces sucked in by it through during the breaks mechanical means can be discharged. In the known device but must the punch stroke must be so large that the workpiece itself goes through completely from the punch is driven through the pull shaft. A shortening of the working stroke of the drawing punch is therefore not achieved by the known - facility.
Auf der Zeichnung ist in Abb. i ein Ziehstempel Z dargestellt, dessen Stirnfläche a siebartig durchlöchert ist, so daß die in den Hohlraum b des Ziehstempels bei ,e eingeblasene Druckluft in das Innere des Papierbeutels c eintreten kann.On the drawing, a drawing punch Z is shown in Fig. I, whose End face a is perforated like a sieve, so that the into the cavity b of the drawing punch at, e blown compressed air can enter the interior of the paper bag c.
Abb. z veranschaulicht das Abziehen des Papierbeutels mittels einer Saugdüse d. Die Mündung dieser Saugdüse wird zweckmäßig in ihrer Breite und Höhe der Stirnseite des Papierbeutels angepaßt. Die durch den Pfeil x angedeutete Relativbewegung zwischen Ziehstempel und Saugdüse kann sich sowohl aus der Rückbewegung des Ziehstempels gegenüber der ortsfesten Saugdüse als auch bei bewegter Saugdüse aus der Summe der Differenz der Bewegungen des Ziehstempels und der Saugdüse ergeben:Fig. Z illustrates the removal of the paper bag using a Suction nozzle d. The mouth of this suction nozzle is appropriate in its width and height adapted to the face of the paper bag. The relative movement indicated by the arrow x between the drawing punch and the suction nozzle can result from both the return movement of the drawing punch compared to the stationary suction nozzle and also with a moving suction nozzle from the sum of the The difference between the movements of the drawing punch and the suction nozzle results in:
