Description
Die Erfindung betrifft eine Vorrichtung zum Verschweißen einer Schlauchbeutelfolie, die eine Schweißstation mit einem Arbeitstisch und einer Sonotrode aufweist, dem von einer Transporteinrichtung in einer Transportrichtung das von der Schlauchbeutelfolie umhüllte Stückgut zuführbar ist, dass der Arbeitstisch eine in Transportrichtung verlaufende Öffnung aufweist, in welcher überlappende Endbereich der Schlauchbeutelfolie zu der Sonotrode führbar sind, und dass eine Andrückrolle vorgesehen ist, die der Sonotrode gegenüberliegend angeordnet ist Eine derartige Vorrichtung ist bekannt und wird dazu verwendet, die Längsränder von Schlauchbeutelfolien zu verschweißen, nachdem die zu verpackende Ware von der Schlauchbeutelfolie eingehüllt wurde. Hierzu ist bei der bekannten Vorrichtung vorgesehen, dass die für den Schweißvorgang erforderliche Energie thermisch eingebracht wird, indem die zu verschweißenden Ränder des Schlauchbeutels mit thermischen Schweißwerkzeugen beaufschlagt wird. Ein derartiges thermisches Schweißverfahren ist aber aus einer Reihe von Gründen nachteilig. Insbesondere besteht die Gefahr, dass die thermoplastische Schlauchbeutelfolie beim Verschweißvorgang an den Schweißwerkzeugen haften bleibt, wodurch Schweißnähte von minderer Qualität entstehen: Der Schlauchbeutel wird dadurch oft unbrauchbar.The The invention relates to a device for welding a Tubular bag film containing a welding station with a Worktable and a sonotrode, that of a transport device wrapped in a transport direction of the tubular bag film General cargo can be fed to the work table has an opening extending in the direction of transport, in which overlapping end region of the tubular bag film to the sonotrode are feasible, and that a pressure roller is provided, which is arranged opposite to the sonotrode Such a device is known and used to to weld the longitudinal edges of tubular bag films, after the goods to be packaged have been enveloped by the tubular bag film. For this purpose, it is provided in the known device that for thermally introduced the required energy welding is determined by the edges to be welded of the Tubular bag is subjected to thermal welding tools. Such a thermal welding process is but out a number of reasons disadvantageous. In particular exists the risk that the thermoplastic tubular bag film during welding adheres to the welding tools, creating welds of inferior quality arise: The tubular bag is often unusable.

der
Eine derartige Vorrichtung ist nicht dazu geeignet, bereits mit dem Stückgut befüllte Schlauchbeutel zu verschweißen, da bei einer derartigen Konstellation der Schlauchbeutel samt der in ihm aufgenommenen Ware zwischen der Sonotrode und Andrückrolle durchgeführt werden müsste, so dass eine Beaufschlagung der zu verschweißenden Bahnmaterial-Lagen durch die Andrückrolle nicht mehr möglich ist.A Such device is not suitable already with the piece goods to fill filled tubular bags, as at such a constellation of the tubular bag together with in him picked goods between the sonotrode and pressure roller would have to be carried out so that an admission the web material layers to be welded by the pressure roller is no longer possible.
Die
Es ist daher Aufgabe der vorliegenden Erfindung, eine Vorrichtung der eingangs genannten Art derart weiterzubilden, dass ein einfaches Verschweißen einer bereits Stückgut umgebenden Schlauchbeutelfolie zu einem Schlauchbeutel ermöglicht wird.It is therefore an object of the present invention, a device of The aforementioned type such that a simple Welding a already general cargo surrounding Tubular bag film allows for a tubular bag becomes.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Sonotrode mit ihrer Längsachse zum Arbeitstisch orthogonal verlaufend angeordnet ist, dass die Sonotrode als eine scheibenförmig ausgebildete, einseitig gelagerte Sonotrode ausgebildet ist, die eine im wesentlichen plane erste Stirnfläche und eine in Umfangsrichtung verlaufende Arbeitsfläche, eine zweite Stirnfläche und einen an diesen anschließende Sonotrodenkörper aufweist, wobei die Sonotrode derart in der Schweißstation angeordnet ist, dass ihre erste Stirnflächen die Arbeitsfläche des Arbeitstisches nicht oder nur unwesentlichen überragt, dass der an die zweite Stirnfläche der Sonotrode anschließende längliche Sonotrodenkörper mittels einer Lagerung in der Schweißstation gelagert ist, und dass die Achse der der Sonotrode gegenüberliegend angeordneten Andrückrolle im wesentlichen orthogonal zum Arbeitstisch verläuft, so dass die Arbeitsfläche der Sonotrode und die Umfangsfläche der Andrückrolle gegenüberliegend angeordnet sind, wobei zwischen der Sonotrode und der Andrückrolle die sich überlappenden Endbereiche der zur verschweißenden Schlauchbeutelfolie durchführbar sind.This object is achieved in that the sonotrode is arranged orthogonal running with its longitudinal axis to the work table that the sonotrode is designed as a disc-shaped, one-sided sonotrode, which has a substantially planar first end face and a circumferentially extending work surface, a second End face and has a subsequent sonotrode this body, wherein the sonotrode is arranged in the welding station that their first faces the work surface of the work table not or only slightly surmounted that adjoining the second end face of the sonotrode elongated sonotrode body by means of a storage in the welding station is mounted, and that the axis of the sonotrode oppositely arranged pressure roller in wesentli Chen orthogonal to the work table, so that the working surface of the sonotrode and the peripheral surface of the pressure roller are arranged opposite, wherein between the sonotrode and the pressure roller, the overlapping end portions of the tubular bag film to be welded are feasible.
Durch die erfindungsgemäßen Maßnahmen wird in vorteilhafter Art und Weise eine Vorrichtung zum Verschweißen einer bereits mit einer Ware gefüllten Schlauchbeutelfolie zu einem Schlauchbeutel geschaffen, welches erlaubt, dass auch bei einer derartigen Ausgangskonstellation zum Versiegeln der Endbereiche der Schlauchbeutelfolie Ultraschall verwendet werden kann. Dies besitzt den Vorteil, dass hierdurch die Schweißqualität der die beiden Endbereiche verbindenden Schweißnaht gegenüber den bekannten Vorrichtungen, bei denen die für den Schweißvorgang erforderliche Energie thermisch eingebracht wird, indem die zu verschweißenden Rändern des Schlauchbeutels mit thermischen Schweißwerkzeuge beaufschlagt werden, verbessert ist. Die beschriebene Vorrichtung ist insbesondere bei beschichteten Folien mit einer innen liegenden Beschichtung von Vorteil, da hierdurch die Gefahr einer Überhitzung und somit Zerstörung dieser beschichteten Folien reduziert oder eliminiert wird. Ein weiterer Vorteil der erfindungsgemäßen Vorrichtung besteht darin, dass während des Siegelvorgangs, keine Wärme auf das zu verpackende Produkt abgestrahlt wird. Dies ist insbesondere bei wärmeempfindlicher Ware wie z. B. Schokolade oder Eiscreme von Vorteil.By the measures according to the invention will in an advantageous manner, a device for welding an already filled with a product tubular bag film created to a tubular bag, which also allows for such a starting constellation for sealing the end regions the tubular bag film ultrasound can be used. This has the advantage that thereby the welding quality opposite to the weld connecting the two end regions the known devices in which the for the welding process required energy is thermally introduced by the edges to be welded of the tubular bag acted upon by thermal welding tools be improved. The device described is particularly useful coated films with an internal coating of Advantage, because of the risk of overheating and thus reducing destruction of these coated films or eliminated. Another advantage of the invention Device is that during the sealing process, no Heat is radiated to the product to be packaged. This is especially in heat-sensitive goods such. As chocolate or ice cream advantage.
Die rotierende Andrückrolle sowie die rotierende Sonotrode besitzen den Vorteil, dass hierdurch eine Faltenbildung in der zu verschweißenden Folie während des Schweißvorgangs vermieden wird.The rotating pressure roller and the rotating sonotrode have the advantage that thereby wrinkling in the zu welding film during the welding process is avoided.
Eine vorteilhafte Weiterbildung der Erfindung sieht vor, dass die Sonotrode mittels zweier Lagerstellen auf einer Halterung gelagert ist, und dass die erste Lagerstelle von der Mittelebene der scheibenförmige Sonotrode einen Abstand aufweist, der im wesentlichen gleich einem Viertel der Wellenlänge der verwendeten Ultraschallschwingung ist, und dass die zweite Lagerstelle von der Mittelebene der Sonotrode einen Abstand aufweist, der im wesentlichen gleich drei Viertel der Wellenlänge der verwendeten Ultraschallschwingung ist.A advantageous development of the invention provides that the sonotrode is mounted on a holder by means of two bearings, and that the first bearing point of the median plane of the disc-shaped Sonotrode has a distance that is substantially equal to a Quarter of the wavelength of the ultrasonic vibration used is, and that the second bearing point of the midplane of the sonotrode has a distance that is substantially equal to three quarters the wavelength of the ultrasonic vibration used.
Eine derartige Maßnahme besitzt den Vorteil, dass hierdurch besonders vibrationsarme Lagerung der Sonotrode in der Vorrichtung ermöglicht ist.A Such measure has the advantage that thereby particularly low-vibration mounting of the sonotrode in the device is possible.
Weitere vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.Further advantageous developments of the invention are the subject of the dependent claims.
