KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Es gibt Tütenaufblasmaschinen, bei denen die Tüte auf ein Mundstück geschoben und mittels einer luftpumpenartigen Vorrichtung aufgeblasen wird. Gegenstand der Erfindung bildet nun eine Vorrichtung zum selbsttätigen Festhalten der Tüte oder des Beutels während der Blasperiode, so daß es nicht nötig ist, den Beutel oder die Tüte solange festzuhalten. There are bag inflation machines in which the bag is pushed onto a mouthpiece and is inflated by means of an air pump-like device. Subject of the invention now forms a device for automatically holding the bag or bag during the blowing period, so that it is not necessary to hold the bag or bag for that long.
ίο Gemäß der Erfindung wird zu diesem Zweck oberhalb und unterhalb der am Luftzylinder befestigten und das eigentliche Mundstück bildenden Blechtülle je eine Klappe angeordnet, die um ein auf der Tülle angebrachtes Scharnier drehbar und durch einen Stoffbalg mit dem Luftzylinder verbunden ist.ίο According to the invention is used for this purpose above and below those attached to the air cylinder and forming the actual mouthpiece Sheet metal grommet each has a flap arranged around a hinge attached to the grommet rotatable and connected to the air cylinder by a fabric bellows.
Durch die Zeichnung wird der Erfindungsgegenstand näher erläutert, und zwar zeigen: The subject of the invention is explained in more detail by the drawing, namely show:
Fig. ι einen Längsschnitt durch die Blasvorrichtung, Fig. Ι a longitudinal section through the blower,
Fig. 2 eine vordere Ansicht des Mundstücks, Fig. 3 eine Draufsicht undFig. 2 is a front view of the mouthpiece, Fig. 3 is a plan view and
Fig. 4 einen Schnitt durch dasselbe.Fig. 4 is a section through the same.
Am Luftpumpenzylinder a, dessen Boden b mit Klappe c versehen ist, ist noch ein Anschlag e und ein Führungsring f und Dichtungsring g für den Kolben h mit seiner Feder i angebracht. Ferner ist k die am Zylinder α angebrachte Mundstücktülle, die vorn abgeschrägt ist, damit man die Tüte 0 leicht aufstecken kann; I sind die Klappen. Die Bälge m und die Anschläge η begrenzen den Hub dieser Klappen /. Drückt man nun von oben auf den Kolben, so drückt die dadurch verdichtete Luft auch auf die Klappen I, sie faltet die Bälge m auseinander und drückt diese Klappen I gegen die Mundstücktülle k, wodurch die auf das Mundstück geschobene Tüte festgehalten wird. Beim Nachlassen des Druckes und Hochgehen des Kolbens saugt die von unten durch die Löcher d und die sich öffnende Klappe c eintretende Luft die Klappen I wieder hoch und die Tüte kann abgenommen werden, oder fällt von selbst ab. A stop e and a guide ring f and sealing ring g for the piston h with its spring i are attached to the air pump cylinder a, the bottom b of which is provided with a flap c. Furthermore, k is the mouthpiece nozzle attached to the cylinder α , which is beveled at the front so that the bag 0 can be easily attached; I are the flaps. The bellows m and the stops η limit the stroke of these flaps /. If the piston is now pressed from above, the air compressed thereby also presses on the flaps I, it folds the bellows m apart and presses these flaps I against the mouthpiece spout k, whereby the bag pushed onto the mouthpiece is held in place. When the pressure is released and the piston goes up, the air entering from below through the holes d and the opening flap c sucks the flaps I up again and the bag can be removed or falls off by itself.
