Description

Vorrichtung zum Heißversiegeln von Seitenfaltenverschlüssen von Behältern aus Papier, Karton od. dgl. Device for the heat sealing of gusset closures of containers made of paper, cardboard or the like.

Die Erfindung betrifft eine Vorrichtung zum Verschließen von Behältern mit dachförmigem Faltversohluß und nach innen gefalteten Giebelflächen aus teilweise oder ganz thermoplastisch beschichtetem Papier, Karton od. dgl., deren zu verbindende Teile über Falt-und Umlegeweichen den Preßwerkzeugen zugeführt werden.The invention relates to a device for closing containers with roof-shaped pleated insole and inwardly folded gable surfaces made of partially Or completely thermoplastically coated paper, cardboard or the like. Their to be connected Parts are fed to the pressing tools via folding and folding switches.

Bei den bekannten Vorrichtungen zum Verschließen derartiger Faltverschlüsse werden die zu verschließenden Teile nach erfolgter Vorfaltung mit Hilfe von Faltweichen zusammengelegt und in den Bereich der Preßwerkzeuge gebracht. Das Verpressen der miteinander zu verbindenden Teile erfolgt dann unter gleichzeitiger Einwirkung von Druck und Wärme. Es hat sich aber gezeigt, daß die miteinander verpreßten Teile beim Nachlassen des Preßdruckes sich zuweilen wieder voneinander lösen. Das Lösen der Verschlußteile ist darauf zurückzuführen, daß sich der durch die Wärmeeinwirkung plastifizierte Kunststoff noch nicht verfestigt hat und die Verschlußteile auf Grund ihrer Eigenspannung zur Rückfederung neigen.In the known devices for closing such folding closures the parts to be closed are after the prefolding with the help of folding switches collapsed and brought into the area of the pressing tools. The pressing of the Parts to be connected to one another then take place under the simultaneous action of Pressure and heat. But it has been shown that the parts pressed together when the pressure is released, they sometimes come apart again. The loosening the closure parts is due to the fact that the by the action of heat plasticized plastic has not yet solidified and the closure parts due their internal stress tend to spring back.

Insbesondere macht sich dieser Nachteil dann bemerkbar, wenn die zu verbindenden Teile unmittelbar vor dem Verpressen gefaltet und umgelegt werden. Beispielsweise ist bei Behältern, die mit einer die Verschlußfaltung abdeckenden Verschlußklappe versehen sind, in der um 1800 umgelegten Verschlußklappe eine erhebliche Eigenspannung verhanden, die das Lösen der Klebestellen verursacht.This disadvantage is particularly noticeable when the connecting parts are folded and turned over immediately before pressing. For example, in the case of containers with a fold that covers the closure Closure flap are provided, in the flap folded around 1800 a considerable Residual stress negotiate that causes the splices to loosen.

Zur Behebung dieser Nachteile wird nun der Neuerung entsprechend vorgeschlagen, geheizte Fall-und Umlegeweichen zu verwenden, denen sich gekühlte Preßwerkzeuge unmittelbar anschließen. Durch diese Maßnahme wird erreicht, daß der durch die erwärmten Faltweichen und durch die sich anschließende Heizschiene plastifizierte Kunststoff beim Pressen mit den gekühlten Preßbacken sofort erstarrt und somit die Verschlußteile fest verbindet. Ein weiterer Vorteil besteht darin, daß die Preßzeit durch das Erwärmen innerhalb der Faltweichen bzw. der Heizschiene und das Pressen mit gekühlten Preßwerkzeugen wesentlich verringert wird, wodurch sich ein schnellerer Arbeitstakt und damit eine höhere Leistung der Maschine ergibt. Die Preßwerkzeuge sind dabei mit einer Kühlvorrichtung in Form eines Wasserumlaufes versehen.In order to remedy these disadvantages, it is now proposed according to the innovation, Use heated case and turnouts, which are cooled pressing tools connect immediately. This measure ensures that the heated by the Foldable switches and plastic plasticized by the adjacent heating rail when pressed with the cooled press jaws solidified immediately and thus the locking parts firmly connects. Another advantage is that the pressing time is reduced by heating within the folding switches or the heating rail and pressing with cooled pressing tools is significantly reduced, resulting in a faster work cycle and thus a results in higher machine performance. The pressing tools are equipped with a cooling device provided in the form of a water circuit.

Den Fall- schienen 3 schließt sich eine Heizschiene 4 mit Schlitz 5 und Heizung 6 an. Durch die Heizung 6 werden die Faltsohienen 3 mit- erwärmt so daß die zu verbindenden thermoplastisch beschichteten Teile schon während des Faltvorganges vorgewärmt werden. Die eigentliche Aktivierung des Kunststoffauftrages geschieht während des Durchlaufes des fertig gefalteten dachförmigen Verschlusses durch den Schlitz 5 der Heizschiene 4. Nach Durchlauf durch die Heizschiene 4 werden die Behälter 1 den sich u=ittelbar anoohlie- Senden Preßwerkzeugen 7. 8, die aus einer beweglichen Preßbaoke 7 und aus einer feststehenden Preßbaoke 8 bestehen, zugeführt.

The case- rails 3 is followed by a heating rail 4 with slot 5 and heater 6. Through the heater 6, the folded rails 3 are heated so that the thermoplastic coated to be joined Parts are preheated during the folding process. The actual activation of the plastic application takes place during the passage of the completely folded roof-shaped closure through the slot 5 of the heating rail 4.
