Description

Vorrichtung zum Herstellen von gefüllten Aufgußbeuteln Zur Herstellung von mit Tee, Kaffee od. dgl. gefüllten Aufgußbeuteln wird naßfestes, durchlässiges Papier verwendet. Dieser Werkstoff wird bisher zwecks Bildung der Verschluß- und Verbindungsnähte durchgehend mit einer heißsiegelfähigen Beschichtung, beispielsweise mit einer dünnen Lackschicht versehen. Die aus derartigen Werkstoffen hergestellten Aufgußbeutel weisen Kissenform auf und sind mit wenigstens drei Randsiegelnähten verschlossen.Device for the production of filled infusion bags For production Infusion bags filled with tea, coffee or the like become wet-strength, permeable Paper used. This material is so far for the purpose of forming the closure and Joint seams with a heat-sealable coating, for example provided with a thin layer of varnish. Those made from such materials Infusion bags are pillow-shaped and have at least three edge sealing seams locked.

Bei den bekannten Aufgußbeuteln hat sich als Nachteil herausgestellt, daß durch die Beschichtung und die Rückstände der Lösungsmittel, mit denen ein Teil der Beschichtung vom Beutelwerkstoff entfernt wird, um dessen Durchlässigkeit wieder herzustellen, der Geschmack des zubereiteten Getränkes und insbesondere von Tee beeinflußt wird. In the case of the known infusion bags, it has been found to be a disadvantage that through the coating and the residues of solvents with which a part the coating is removed from the bag material in order to restore its permeability to produce the taste of the prepared beverage and especially of tea being affected.

Zur Vermeidung dieser Nachteile geht die Erfindung von solchen bekannten Vorschlägen aus, bei denen zum Herstellen von Aufgußbeuteln aus naßfestem, durchlässigem Papier deren Verbindungsnähte durch Heißsiegeln gebildet werden, so daß auf den verwendeten Werkstoffbahnen lediglich im Bereich der zu versiegelnden Nähte Streifen eines heißsiegelfähigen Klebemittels mittels Auftragwalzen aufgetragen werden. Dabei ist auch als an sich bekannt anzusehen die Verwendung eines aus einer Strangpresse austretenden dünnen Fadens, der zwischen zwei Folien als Klebe- und Verbindungsmittel eingebracht wird. Ferner ist es bereits bekannt gewesen, für den beabsichtigten Zweck zwei Bahnen kreuzweise zusammenzuführen. Schließlich wurde auch schon eine Vorrichtung vogeschlagen, mit welcher bei Verpakkungsmaschinen zum Abfüllen pulverigen und körnigen Gutes in Streifenpackungen zwischen zwei heißsiegelbaren Folienbändern das erste Folienband mit einer Meßzylindertrommel in etwa gleicher Geschwindigkeit umlaufend diese teilweise umspannen zu lassen und das Füllgut auf dem tangential ablaufenden Folienband liegend aus den Meßzylindern auszustoßen. To avoid these disadvantages, the invention is based on such known ones Proposals from where to make infusion bags from wet-strength, permeable Paper whose seams are formed by heat sealing, so that on the strips of material used only in the area of the seams to be sealed a heat-sealable adhesive can be applied by means of applicator rollers. Included is also to be regarded as known per se the use of one from an extrusion press emerging thin thread between two foils as an adhesive and connecting means is introduced. Furthermore, it has already been known for the intended Purpose to merge two tracks crosswise. Eventually it became one Device proposed with which powdery packaging machines are used for filling and granular goods in strip packs between two heat-sealable foil strips the first film strip with a measuring cylinder drum at approximately the same speed to partially encircle this and the filling material on the tangential eject the running film tape lying down from the measuring cylinders.

Demgegenüber bezieht sich die Erfindung auf eine Vorrichtung zum Herstellen von gefüllten Aufguß beuteln aus zwei naßfesten, durchlässigen, in zuemander senkrechten Richtungen zugeführten Papierbahnen, auf deren Rändern zur Herstellung der Beutelnähte heißsiegelfähige Klebstoffschichten aufgebracht sind, so daß nach dem Hauptmerkmal der Erfindung diese Vorrichtung sich kennzeichnet durch eine Einrichtung, welche die eine Bahn in Einzelzuschnitte abtrennt und diese auf ein im rechten Winkel zur Bahnrichtung angeordnetes endloses Förderband übergibt, das seinerseits die Zuschnitte um die Trommel einer Dosiervorrichtung an sich bekannter Art führt und dann die derart mit einer Füllgutmenge versehenen Zuschnitte einer weiteren Einrichtung zuleitet, welche die zweite Werkstoffbahn über die Zuschnitte führt, mit diesen zu Beuteln versiegelt und diese abtrennt. Erst durch diese erfindungsgemäße Gesamtkombination der gekennzeichneten Einzelmerkmale wird der wesentliche Vorteil erreicht, daß die Vorrichtung nicht nur besonders leistungsfähig, sondern auch einfach und raumsparend im Aufbau ist, und daß sie außerdem das kontinuierliche Auftragen der Klebestreifen auch auf die quer zugeführten Zuschnitte ermöglicht, was besonders bei Verwendung von mit Düsen arbeitenden Auftragvorrichtungen wesentlich ist. Die Erfindung weist als weiteren Vorteil die Möglichkeit auf, wahlweise Einfach- oder Doppelkammerbeutel herzustellen, ohne daß eine wesentliche Umstellung der Maschine notwendig ist. In contrast, the invention relates to a device for Manufacture of filled infusion bags from two wet-strength, permeable, in one another paper webs fed in perpendicular directions, on their edges for production of the bag seams heat-sealable adhesive layers are applied so that after the main feature of the invention this device is characterized by a device, which separates one web into individual blanks and these on one at right angles to the web direction arranged endless conveyor belt passes, which in turn the Blanks around the drum of a metering device of a known type and leads then the blanks of a further device which are provided with a quantity of filling material in this way feeds, which leads the second web of material over the blanks, with these sealed into bags and separates them. Only through this overall combination according to the invention of the identified individual features, the essential advantage is achieved that the Device not only particularly efficient, but also simple and space-saving is under construction, and that it also has the continuous application of the adhesive tape also allows the cross-fed blanks, which is especially useful when using of nozzle applicators is essential. The invention has Another advantage is the option of either single or double chamber bags without a substantial change of the machine is necessary.

Ferner können die Steuermittel für das gleichmäßige Zuführen der Zuschnitte zu den Siegelwalzen ohne weiteres einfachster und durchaus bekannter Art sein oder aber auch völlig entfallen, wenn das Förderband mit Mitnehmern versehen ist und mit den Siegelwalzen zusammen zwangläufig angetrieben wird.Furthermore, the control means for the uniform feeding of the blanks to the sealing rollers easily or of the simplest and well-known type but also completely omitted if the conveyor belt is provided with drivers and is inevitably driven together with the sealing rollers.

Weitere, nur im Zusammenhang mit dem Hauptmerkmal der Erfindung zu schützende Erfindungsmerkmale kennzeichnen sich dadurch, daß zum Versiegeln der Zuschnitte mit der zweiten Werkstoffbahn und zum Abtrennen der fertigen Beutel ein Rollenpaar vorgesehen ist, das beheizte Querstege aufweist und mit an diesen Querstegen angeordneten Messern und Gegenmessern ausgerüstet ist, bzw. daß die Do- siervorrichtung in an sich bekannter Weise aus einer in senkrechter Ebene umlaufenden Trommel mit radial angeordneten Meßkammern besteht, die unter einem Vorratstrichter vorbeilaufen. Further, only in connection with the main feature of the invention too protective features of the invention are characterized in that for sealing the Blanks with the second web of material and for severing the finished bag A pair of rollers is provided, which has heated transverse webs and with these transverse webs arranged knives and counter knives, or that the Do- adjustment device in a manner known per se from a drum rotating in a vertical plane there is radially arranged measuring chambers that pass under a storage funnel.
