Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Verschweißen eines becherartigen Behälters mit einem Aufreißdeckel mittels Ultraschall gemäß dem Oberbegriff des Anspruchs 1 bzw. dem Oberbegriff des Anspruchs 7.The The invention relates to a method and a device for welding a cup-shaped container with a tear-open lid by means of ultrasound according to the preamble of claim 1 or the preamble of claim 7.
Es ist bekannt, Kunststoffe oder mit Kunststoff beschichtete Bauteile mittels Ultraschall miteinander zu verschweißen. Bei der Ultraschallverschweißung kann der Energieeintrag derart gesteuert werden, dass die Materialien der miteinander zu verschweißenden Bauteile an den gewünschten Stellen erweichen und sich miteinander verbinden. Bei einem anderen Verfahren zum Verbinden von Kunststoffen wird die Energie mittels Heizelementen eingetragen, wobei von außen die Heizenergie, mit welcher die Bauteile plastifiziert werden, eingebracht werden muss. Hierbei wird auf jeden Fall ein Bauteil über seine gesamte Dicke plastifiziert, was unter Umständen unerwünscht ist. Außerdem kann bei diesem Verfahren der Energieeintrag nicht so gezielt auf eine Stelle konzentriert werden, wie beim Ultraschallverschweißen.It is known, plastics or plastic-coated components to be welded together by means of ultrasound. In ultrasonic welding can the energy input are controlled so that the materials to be welded together Components to the desired Make soften and connect with each other. With another Method of joining plastics is the energy by means of Entered heating elements, from the outside, the heating energy, with which the components are plasticized, must be introduced. in this connection will definitely be a component over its entire thickness plasticized, which may be undesirable. Furthermore In this method, the energy input can not be so targeted to concentrate a spot, as in ultrasonic welding.
Das Anbringen eines Aufreißdeckels auf einen becherartigen Behälter erfolgt mittels Heizelementen, was relativ lange dauert, und wobei der Rand des Aufreißdeckels vollflächig mit dem flanschartigen Rand des Behälters verschweißt wird. Eine großflächige Verschweißung hat zwar den Vorteil, dass sie üblicherweise eine große Sicherheit hinsichtlich ihrer Dichtigkeit bietet, es muss jedoch in Kauf genommen werden, dass der Aufreißdeckel nur mit Mühe vom Behälter entfernt werden kann.The Attaching a tear-open lid on a cup-shaped container takes place by means of heating elements, which takes a relatively long time, and wherein the edge of the tear-open lid entire area is welded to the flange-like edge of the container. A has extensive welding Although the advantage that they usually a big Safety in terms of their tightness offers, but it must be taken into account that the tear-open only with difficulty from the container can be.

Ein weiterer Nachteil beim Stand der Technik wird darin gesehen, dass beim Aufreißen des Deckels dieser in der Regel vollständig vom Becher abgerissen wird, so dass er als separates Teil oftmals weggeworfen wird und dann der Behälter nicht wieder verschlossen werden kann.One Another disadvantage of the prior art is seen in that when tearing open the lid of this usually completely demolished from the cup so that it is often thrown away as a separate part and then the container can not be closed again.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zum Verschweißen eines becherartigen Behälters mit einem Aufreißdeckel bereit zu stellen, bei welchem der Aufreißdeckel zwar mit Sicherheit am Behälter befestigt ist, der Aufreißdeckel sich jedoch mit geringem Kraftaufwand erstmalig öffnen lässt und trotzdem sichergestellt ist, dass der Aufreißdeckel am Behälter verbleibt.Of the Invention is based on the object, a method and an apparatus for welding a cup-like container with a tear-open lid to provide, in which the tear-off lid certainly with security on the container is attached, the tear-open lid However, it can be opened for the first time with little effort and still ensured is that the tear-open lid on the container remains.
Diese Aufgabe wird mit einem Verfahren gelöst, welches die Merkmale des Anspruchs 1 aufweist.These The object is achieved by a method which has the features of Claim 1 has.
Beim erfindungsgemäßen Verfahren wird der Rand des Deckels mit dem Rand des Bechers mittels einer Ultraschallschweißsonotrode verschweißt. Dabei wird in einem ersten Verfahrensschritt ein erster Umfangsabschnitt des Randes des Deckels mit dem Becher verschweißt, und in einem zweiten Verfahrensschritt der restliche Umfangsabschnitt. Auf diese Weise wird zum einen sichergestellt, dass der komplette Rand des Deckels am Becher angeschweißt wird, wobei aber der Rand im einen Umfangsabschnitt weniger stark als im anderen Umfangsabschnitt am Becher angeschweißt wird. Die Dichtigkeit ist nach wie vor gewährleistet, wohingegen die Aufreißkraft beim weniger stark angeschweißten Rand geringer ist. Ein derart angeschweißter Aufreißdeckel kann mit geringem Kraftaufwand aufgerissen werden, und verbleibt dennoch über den zweiten Umfangsabschnitt am Becher, da zum vollständigen Abreißen des Aufreißdeckels ein hoher Kraftaufwand erforderlich ist, welcher in der Regel nicht aufgewandt wird. Ein Becher mit einem derart am Becherrand befestigten Aufreißdeckel kann problemlos wieder verschlossen werden, da der Aufreißdeckel am Becherrand verbleibt.At the inventive method The edge of the lid with the edge of the cup by means of a Ultraschallschweißsonotrode welded. In this case, in a first method step, a first peripheral section the edge of the lid welded to the cup, and in a second process step the remaining peripheral portion. This ensures, on the one hand, that the complete edge of the lid is welded to the cup, but where the edge in a peripheral portion less than in the other peripheral portion is welded to the cup. The tightness is still guaranteed whereas the tearing force when less strongly welded Edge is lower. Such a welded Aufreißdeckel can with little effort be torn open, and yet remains over the second peripheral portion on the cup, because the complete Tear off of the tear-open lid a high amount of effort is required, which is usually not is spent. A cup with such attached to the edge of the cup The easy open can be closed again easily, since the tear-open lid remains on the edge of the cup.
Um den zweiten Umfangsabschnitt des Randes des Aufreißdeckels mit dem Becherrand zu verschweißen, wird entweder das Werkzeug oder das Werkstück oder werden beide gegeneinander verfahren. Es kann also mit dem gleichen Werkzeug zuerst der eine Umfangsabschnitt und dann der andere Umfangsabschnitt angeschweißt werden. Mit Vorzug liegt der Becher in einer Becheraufnahme, die als Sonotrode oder Gegenwerkzeug ausgebildet werden kann, wobei am Aufreißdeckel nacheinander der erste Schweißschritt und darin der andere Schweißschritt durchgeführt wird.To weld the second peripheral portion of the rim of the tear-open lid to the rim of the cup, either the tool or the workpiece will be traversed or both will move against each other. It can therefore be welded with the same tool first of a peripheral portion and then the other peripheral portion. With preference, the cup is in a cup holder, which as So Notrode or counter tool can be formed, wherein on the tear-open successively the first welding step and therein the other welding step is performed.
Um unterschiedlich starke Verschweißungen zu erhalten, wird beim einen Schweißvorgang die Spalthöhe zwischen der Ultraschallschweißsonotrode und dem Gegenwerkzeug geringer als beim anderen Schweißvorgang eingestellt.Around To get different degrees of welding, is the a welding process the gap height between the ultrasonic welding sonotrode and the counter tool lower than the other welding operation set.
Bei einer Weiterbildung dauert der eine Schweißvorgang länger als der andere Schweißvorgang. at In one development, one welding process takes longer than the other welding process.
Bei geringerem Schweißspalt wirken höhere Kräfte auf die miteinander zu verschweißenden Bauteile ein, wodurch es zu einer größeren Plastifizierung kommt.at less welding gap act higher forces to weld together Components, resulting in a greater plasticization.
Wird die Ultraschallschweißsonotrode vom einen Umfangsabschnitt auf den anderen verschoben, kann gleichzeitig die Spalthöhe geändert werden.Becomes the ultrasonic welding sonotrode moved from one peripheral section to the other, can simultaneously the gap height changed become.
Bei einem Ausführungsbeispiel ist vorgesehen, dass wenigstens zwei Ultraschallschweißsonotroden und/oder Gegenwerkzeuge für die beiden Umfangsabschnitt verwendet werden. Bei dieser Variante können die beiden Schweißvorgänge gleichzeitig durchgeführt werden, wobei bei der einen Ultraschallschweißsonotrode eine kürzere Schweißzeit eingestellt wird, als bei der anderen und eine andere Spalthöhe verwendet wird, als bei der anderen Ultraschallschweißsonotrode. Bei dieser Variante der Erfindung können höhere Taktzeiten erzielt werden, da lediglich einmal mit dem Werkzeug an das Werkstück herangefahren werden muss. Dabei werden der erste und der zweite Schweißschritt gleichzeitig durchgeführt.at an embodiment it is provided that at least two ultrasonic welding sonotrodes and / or counter tools for the two peripheral section are used. In this variant can the two welding processes simultaneously carried out be set with the one ultrasonic welding sonotrode a shorter welding time is used as in the other and a different gap height, than at the other ultrasonic welding sonotrode. In this variant of the invention, higher cycle times can be achieved because only once approached with the tool to the workpiece must become. In this case, the first and the second welding step performed simultaneously.
Die Schweißzeiten und Spalthöhen sind dabei so eingestellt, dass der eine Umfangsabschnitt leicht geöffnet werden kann, wobei der andere Umfangsabschnitt den Aufreißdeckel am Behälterrand sicher festhält.The welding times and gap heights are set so that the one peripheral section easily open can be, wherein the other peripheral portion of the Aufreißdeckel safe at the edge of the container holds.
