Description

Vorrichtung zum Abstreifen von Überzügen, besonders von Flaschenkapseln, aus Stoffen, die zusammenhängende Häutchen bilden, von der Tauchform Die Herstellung von kapselförmigen überzügen, wie sie besonders zum Verschließen von Flaschen benutzt werden, erfolgt durch Tauchen entsprechender Formen in Lösungen von Stoffen, welche beim Verdunsten oder durch chemische Einwirkung zusammenhängende Häutchen geben. Die fertigen Kapseln werden in verschiedener Weise von der Form abgestreift. Dieses Abstreifen *erfolgte bisher in der Regel ohne Umstülpen der Kapsel. Die der Tauchform anliegende Seite der Kapsel blieb also auch Innenseite der fertigen Kapsel, obgleich sie glänzender ist als die Außenseite. Das wohl bereits geübte nachträgliche Umstülpen mit der Hand ist aber umständlich und erfordert viel Arbeitszeit.Device for stripping coatings, especially bottle caps, from substances that form coherent skins, from the dipping form The production of capsule-shaped coatings, such as those used in particular for closing bottles are done by dipping appropriate forms in solutions of substances, which give cohesive skins when evaporating or due to chemical action. The finished capsules are stripped from the mold in various ways. This Up until now, stripping * has generally been carried out without turning the capsule inside out. That of the diving form The adjacent side of the capsule remained on the inside of the finished capsule, although it is shinier than the outside. The already practiced turning inside out by hand, however, is cumbersome and requires a lot of working time.

Gegenstand der Erfindung ist eine Vorrichtung, welche gestattet, sofort beim Abziehen der Kapsel von der Form das Umstülpen vorzunehmen. Zu diesem Zweck wird das Abstreifen jeder Kapsel durch, ringförmige Greifer bewirkt, deren Gummibacken durch Federdruck gegen die Kapsel gepreßt werden, worauf sie gegen das Ende der Tauchform verschoben werden, die Kapsel von der Form abstreifen und über einen an die Kappe der überzogenen Form angedrückten, entsprechend geformten Stempel umstülpen. Auf diese Weise kommt die bisherige Innenseite nach außen zu liegen. Die Kapsel kann mit ihrem rauhen Rande verwendet werden, man kann diesen Rand aber auch vorher abschneiden, so daß sie gleich den für den Verkauf erforderlichen glatten Rand -hat. Den Greifer bildet man zweckmäßig so aus, daß er den Rand der Kapsel an der Schnittseite erfassen kann, so daß das -Umstülpen vollständig und ohne Faltenbildung erfolgt. Der Stempel kann als Rohr ausgebildet sein, welches an der Berührungsstelle mit der Kapsel entsprechend erweitert ist. Das Entfernen der umgestülpten Kapsel von dem Stempel erfolgt, nachdem die Tauchform entfernt ist, durch Abblasen mit Luft oder auch durch Wasserdruck. Das Ende des Stempels kann aus den verschiedensten Materialien bestehen, vorteilhaft ist die Verwendung von Gummi. Für den technischen Betrieb vereinigt man eine größere Zahl von Stülpvorrichtungen und treibt sie gemeinsam an. Die Zeichnung gibt In Abb. i und a Vertikaldurchschnitte durch die Abstreifvorrichtung. Nach Abb. i befindet sich auf der Tauchforints eine Kapsel b. Diese ist durch Tauchen in Lösungen entstanden und hierauf in. der Nähe des oberen Randes durch einen kreisförmigen Schnitt mit einer glatten Schnittfläche versehen worden. Gegen die Kapselt und ihre Tauchform a wird eine entsprechend geformte Gegenform c gedrückt. Hierauf wird die Kapsel von den Gummibakkend der ringförmigen oder aus Teilen eines Ringes bestehenden Greifvorrichtung erfaßt, die Backend werden durch Federdruck gegen die Kapsel b gepreßt. Hierauf verschiebt man die Greifvorrichtung in der Richtung nach der Gegenform c. Hierbei wird die Kapsel von der Tauchforma abgestreift und über die Gegenform c hinweggeschoben. Wenn sich hierbei zunächst in der Kapsel b eine Falte bildet, wird die Greifvorrichtung d etwas gelüftet bis zum Kapselrand emporgeschoben und nach Wiederandrücken nochmals in der Richtung von a nach c heruntergeschoben. Hierdurch wird das vollständige Umstülpen der Kapsel bewirkt; und die Kapsel nimmt dann auf der Gegenform c etwa di° in Abb. a dargestellte Stellung ein. Der abgeschnittene ungleichmäßige Kapselrand bleibt auf der Tauchform hängen und wird nach dem Abheben der Forma durch eine besondere Einrichtung abgestreift.The invention relates to a device which allows immediately to turn it inside out when pulling the capsule off the mold. To this end each capsule is stripped off by means of ring-shaped grippers, their rubber jaws are pressed by spring pressure against the capsule, whereupon they are against the end of the Dipping mold are moved, strip the capsule from the mold and put it on Turn over the cap of the coated mold with the correspondingly shaped stamp pressed down on it. In this way, the previous inside comes to lie on the outside. The capsule can be used with its rough edge, but you can also use this edge beforehand Cut off so that it has the smooth edge required for sale. The gripper is expediently designed in such a way that it touches the edge of the capsule on the cut side can grasp, so that the everting takes place completely and without wrinkling. The stamp can be designed as a tube, which at the point of contact with the capsule is expanded accordingly. Removing the everted capsule from the stamp takes place after the dipping form has been removed, by blowing off with air or by water pressure. The end of the stamp can be of the most varied Materials exist, the use of rubber is advantageous. For the technical Operation combines a larger number of everting devices and drives them together at. The drawing shows in Fig. I and a vertical sections through the stripping device. According to fig. I there is a capsule b on the diving forint. This is by diving originated in solutions and then in. near the upper edge by a circular Cut has been provided with a smooth cut surface. Against the capsule and hers Dipping form a is pressed into a correspondingly shaped counter-form c. Then the Capsule from the Gummibakkend the ring-shaped or consisting of parts of a ring Gripping device detected, the backend are pressed against the capsule by spring pressure b pressed. The gripping device is then moved in the direction of the counter-mold c. Here, the capsule is stripped from the immersion mold and over the counter-mold c pushed away. If a crease initially forms in capsule b, the gripping device d is slightly lifted up to the edge of the capsule and pushed after pressing it again pushed down again in the direction from a to c. Through this the capsule is completely everted; and the capsule then picks up the counter-shape c about di ° in Fig. a position shown. The cut one uneven capsule edge gets stuck on the dipping form and becomes after it is lifted off stripped of forma by a special device.
