Description

Die vorliegende Erfindung betrifft eine Vorrichtung und ein Verfahren zum Befestigen von Verschlussfolien an auf Verbundpackungen, insbesondere Getränkepackungen, angeordneten Ausgießelementen.The present invention relates to an apparatus and a method for attaching closure foils to pouring elements arranged on composite packages, in particular beverage packages.

Heute sind Verbundpackungen, insbesondere für Getränke, häufig mit sogenannten Ausgießelementen versehen, um ein Öffnen und ein Wiederverschließen solcher Packungen zu ermöglichen. Damit die Packungen nach dem erstmaligen Öffnen auch wieder zuverlässig verschlossen werden können, werden zu diesem Zweck oftmals insbesondere Schraubverschlüsse verwendet. Allerdings ergibt sich bei den Schraubverschlüssen - wie auch bei den übrigen verwendeten Ausgießelementen - das Problem, dass diese im verschlossenen Zustand keine sehr hohe Gasdichtigkeit aufweisen. Dadurch ist es möglich, dass Gase von außen durch den Verschluss in das Innere der Packung gelangen und so die Haltbarkeit des Packungsinhaltes beeinträchtigen. Somit können unter Umständen die gewünschten langen Haltbarkeitszeiten durch den Hersteller nicht gewährleistet werden. Ebenfalls können sich Qualitäts- und/oder Aromaverluste des abgefüllten Produktes durch Migration von innen nach außen ergeben.Today, composite packages, especially for beverages, are often provided with so-called pouring elements to allow opening and reclosing of such packages. So that the packages can be reliably closed again after the first opening, screw closures are often used for this purpose. However, in the screw caps - as well as in the other pouring elements used - the problem arises that they do not have a very high gas tightness in the closed state. As a result, it is possible that gases from the outside through the closure into the interior of the package and thus affect the durability of the package contents. Thus, under certain circumstances, the desired long shelf life can not be guaranteed by the manufacturer. Also, quality and / or aroma losses of the bottled product can result from migration from the inside out.

Daher hat es sich als notwendig erwiesen, die Ausgießöffnungen der Ausgießelemente unterhalb des Deckelelementes mit einer Verschlussfolie zu überziehen und so gasdicht zu verschließen. Hierzu kann auf der Innenseite der Packung eine Folie über die Öffnung für das Ausgießelement gesiegelt werden, die beim erstmaligen Öffnen der Packung durchstoßen wird. Alternativ dazu ist es auch möglich, die Ausgießöffnung des Ausgießelementes selbst mit einer Verschlussfolie zu versehen, die die Ausgießöffnung abdichtet. Im Falle eines Schraubverschlusses wird erst nach Anbringen dieser Verschlussfolie das Deckelelement aufgeschraubt. Ein derartiges Ausgießelement ist beispielsweise aus der EP 0 505 388 B1 bekannt.Therefore, it has been found necessary to coat the pouring of the pouring elements below the lid member with a sealing film and so close gas-tight. For this purpose, a film can be sealed on the inside of the pack over the opening for the pouring element, which is pierced when opening the package for the first time. Alternatively, it is also possible to provide the pouring opening of the pouring element itself with a sealing film which seals the pouring opening. In the case of a screw cap, the cover element is screwed on only after the attachment of this sealing foil. Such a pouring element is known, for example, from EP 0 505 388 B1.

Insbesondere dann, wenn die Packungen unter aseptischen Bedingungen befüllt werden sollen, ist es wünschenswert, die Verschlussfolie nicht erst nach dem Befüllen an der Ausgießöffnung anzubringen, sondern diese schon vorher im Bereich des Ausgießelementes zu befestigen und die Ausgießöffnung unmittelbar nach dem Sterilisieren und Befüllen mit der Verschlussfolie dicht zu verschließen. Dadurch wird erreicht, dass insbesondere die dem Packungsinhalt zugewandte Seite der Verschlussfolie mit sterilisiert wird.In particular, when the packages are to be filled under aseptic conditions, it is desirable not to attach the sealing film after filling at the pouring opening, but to fix it before in the pouring element and the pouring opening immediately after sterilization and filling with the Close sealing foil tightly. It is thereby achieved that, in particular, the side of the closure film facing the package contents is also sterilized.

Dabei ergibt sich allerdings das Problem, dass es notwendig ist, die Verschlussfolie vor dem Befüllen zuverlässig in der Weise an dem Ausgießelement zu befestigen, dass einerseits ein nachträgliches Versiegeln der Ausgießöffnung ohne Schwierigkeiten möglich ist und andererseits das Befestigen der Verschlussfolie den Herstellungsprozess der Packungen nicht unnötig behindert oder verzögert. Außerdem ist es erforderlich, dass ein Befüllen der Packung bei bereits befestigter Verschlussfolie möglich ist.However, there is the problem that it is necessary to reliably fasten the sealing film to the pouring element before filling in such a way that subsequent sealing of the pouring opening is possible without difficulty and the fixing of the sealing film does not make the production process of the packages unnecessary obstructed or delayed. It is also necessary that a Filling the package is possible with already attached closure foil.

Eine Vorrichtung gemäß dem Oberbegriff des Anspruchs 1 ist aus der GB-A-2 071 565 bekannt.An apparatus according to the preamble of claim 1 is known from GB-A-2 071 565.

Davon ausgehend liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine Vorrichtung und ein Verfahren der eingangs genannten und zuvor näher beschriebenen Art bereitzustellen, mit denen es möglich ist, Verschlussfolien während des Herstellungsprozesses von Verbundpackungen zuverlässig und schnell an auf den Verbundpackungen angeordneten Ausgießelementen zu befestigen.Based on this, the object of the present invention is to provide a device and a method of the type mentioned above and with which it is possible to fasten closure films reliably and quickly to pouring elements arranged on the composite packages during the production process of composite packages.

Vorrichtungsmäßig wird diese Aufgabe gelöst durch das kennzeichnende Merkmal des Anspruchs 1.In terms of apparatus, this object is achieved by the characterizing feature of claim 1.

Mit der Taktfördereinrichtung werden die Verschlussfolien vereinzelt und zu der Zuführeinrichtung gefördert. Die daran vorgesehene Klemmeinrichtung hält jeweils eine Verschlussfolie, die in der Aufnahmeposition von der Taktfördereinrichtung an die Klemmeinrichtung übergeben wird. Danach wird die Verschlussfolie durch die Bewegung der Zuführeinrichtung in die Schweißposition gebracht. Durch die Transporteinrichtung werden die mit Ausgießelementen versehenen Verbundpackungen ebenfalls in den Bereich der Schweißposition transportiert, so dass es dann möglich ist, die vereinzelte Verschlussfolie mittels der Schweißeinrichtung an dem Ausgießelement zu befestigen. Wenn die Verschlussfolie an dem Ausgießelement befestigt ist, gibt die Klemmeinrichtung die Verschlussfolie frei und die Zuführeinrichtung kann sich zurück in die Aufnahmeposition bewegen, um eine weitere Verschlussfolie für das nächste Ausgießelement aufzunehmen.With the clock conveyor, the closure films are separated and conveyed to the feeder. The clamping device provided thereon each holds a sealing film, which is transferred in the receiving position of the clock conveyor to the clamping device. Thereafter, the sealing film is brought by the movement of the feeder in the welding position. By the transport device are with Pouring elements provided composite packages also transported in the region of the welding position, so that it is then possible to attach the sporadic sealing film by means of the welding device to the spout. When the closure foil is attached to the pouring element, the clamping device releases the sealing foil and the feeder can move back to the receiving position to receive another sealing foil for the next pouring element.

Somit ermöglicht zunächst die Taktfördereinrichtung ein Vereinzeln der gegebenenfalls kontinuierlich zugeführten Verschlussfolien. Durch die Klemmeinrichtung, die an der Zuführeinrichtung vorgesehen ist, kann die Verschlussfolie in einer definierten Position dem Ausgießelement zugeführt werden, so dass auch die Stellung, die die Verschlussfolie nach dem Befestigen einnimmt, eindeutig festgelegt ist.Thus, initially the clock conveyor device allows a separation of the optionally continuously supplied closure films. By the clamping device, which is provided on the feed device, the closure film can be supplied in a defined position of the pouring element, so that the position which occupies the sealing film after fastening, is clearly defined.

Nach einer weiteren Ausführungsform der Erfindung erstreckt sich die Klemmeinrichtung in der Schweißposition in Richtung der Mittelachse der Öffnung der auf den Verbundpackungen angeordneten Ausgießelemente und parallel dazu. Dadurch wird erreicht, dass die Verschlussfolien rechtwinklig zur Öffnungsebene abstehend befestigt werden und damit bei dem sich anschließenden Sterilisieren und Befüllen nicht stören.According to a further embodiment of the invention, the clamping device extends in the welding position in the direction of the central axis of the opening of the pouring elements arranged on the composite packages and parallel thereto. This ensures that the closure films are mounted at right angles to the opening plane projecting and thus do not interfere with the subsequent sterilization and filling.

In einer anderen bevorzugten Ausführungsform weist die Zuführeinrichtung einen Hebelarm auf, der um eine Achse schwenkbar ist und an dessen der Achse abgewandtem freien Ende die Klemmeinrichtung angeordnet ist. Damit wird durch eine einfache Schwenkbewegung ermöglicht, dass die Klemmeinrichtung sowohl die Aufnahmeposition als auch die Schweißposition einnehmen kann. Die Achse ist bevorzugt rechtwinklig zur Transportrichtung der Verbundpackungen und in einer Ebene parallel zur Transportebene angeordnet.In another preferred embodiment, the feed device has a lever arm, which is pivotable about an axis and at whose free end facing away from the axis, the clamping device is arranged. This is made possible by a simple pivoting movement that the Clamping device can take both the receiving position and the welding position. The axis is preferably arranged at right angles to the transport direction of the composite packages and in a plane parallel to the transport plane.

Eine weitere Ausgestaltung der Erfindung sieht vor, dass die Zuführeinrichtung mehrere drehbar mit der Achse verbundene Hebelarme aufweist, die sternförmig angeordnet sind. Dadurch wird erreicht, dass während des Zuführens bereits aufgenommener Verschlussfolien zur Schweißposition weitere Verschlussfolien an die Klemmeinrichtungen übergeben werden können, so dass eine höhere Taktrate beim Befestigen der Verschlussfolien erreicht werden kann.A further embodiment of the invention provides that the feed device has a plurality of lever arms rotatably connected to the axis, which are arranged in a star shape. It is thereby achieved that during the feeding of already recorded closure foils to the welding position further closure foils can be transferred to the clamping devices, so that a higher cycle rate can be achieved when fastening the closure foils.

In einer weiteren bevorzugten Ausführungsform sind die Klemmeinrichtungen derart ausgebildet, dass Klemmbacken vorgesehen sind, die zwischen einer geschlossenen und einer geöffneten Stellung hin- und her bewegbar sind, wobei dies weiter bevorzugt auf pneumatischem Wege geschieht. Durch eine derartige Anordnung wird eine zuverlässige Klemmeinrichtung bereitgestellt, die mittels der Pneumatik leicht ansteuerbar ist.In a further preferred embodiment, the clamping devices are designed such that jaws are provided, which are movable back and forth between a closed and an open position, wherein this further preferably takes place pneumatically. By such an arrangement, a reliable clamping device is provided, which is easily controlled by means of pneumatics.

Eine andere Ausführungsform sieht vor, dass die Hebelarme im Bereich der Klemmeinrichtungen einen Zentrierdorn aufweisen, mit dem das Ausgießelement während des Befestigens relativ zu der Verschlussfolie positioniert werden kann. Dadurch wird sichergestellt, dass die Verschlussfolie in einer genau definierten Position relativ zum Ausgießelement befestigt wird.Another embodiment provides that the lever arms in the region of the clamping devices have a centering mandrel, with which the pouring element can be positioned during fastening relative to the closure film. This ensures that the sealing film is fastened in a precisely defined position relative to the pouring element.

Wird zwischen der Taktfördereinrichtung und der Zuführeinrichtung eine Schneideinrichtung vorgesehen, können die Verschlussfolien als Band von der Rolle von der Taktfördereinrichtung gefördert werden und das Vereinzeln der Verschlussfolien erfolgt erst mittels der Schneideinrichtung, nachdem diese in der Klemmeinrichtung fixiert sind.If a cutting device is provided between the clock conveying device and the feeding device, the closing films can be conveyed as a belt from the roller by the clock conveying device and the separating of the closing films takes place only by means of the cutting device after they have been fixed in the clamping device.

Eine weitere Ausführungsform der Erfindung sieht vor, dass der Taktfördereinrichtung eine Stanzvorrichtung vorgeschaltet ist, so dass das Bandmaterial für die Verschlussfolie innerhalb der erfindungsgemäßen Vorrichtung an die gewünschte Form angepasst werden kann. Somit kann beliebiges Bandmaterial verwendet werden.A further embodiment of the invention provides that the punch conveyor is preceded by a punching device, so that the strip material for the sealing film within the device according to the invention can be adapted to the desired shape. Thus, any strip material can be used.

Nach einem weiteren bevorzugten Ausführungsbeispiel ist die Transporteinrichtung derart ausgebildet, dass mit ihr Verbundpackungen mit oben angeordneten Ausgießelementen aufrecht stehend transportiert werden können. Dadurch ist es möglich, die Verschlussfolien direkt vor einem Sterilisieren und späteren Befüllen der Verbundpackungen zu befestigen, so dass die befestigten Verschlussfolien nur für einen kurzen Zeitraum der Gefahr von Beschädigungen ausgesetzt sind.According to a further preferred embodiment, the transport device is designed in such a way that it can be used to transport composite packages with pouring elements arranged on top in an upright position. This makes it possible to fasten the closure foils directly before sterilizing and subsequently filling the composite packages, so that the fastened closure foils are exposed to the risk of damage only for a short period of time.

In weiter bevorzugter Weise verlaufen die Bewegungsrichtungen der Klemmeinrichtungen und der Transporteinrichtung im Bereich der Transporteinrichtung parallel zueinander, wodurch vermieden wird, dass Ausgießelemente mit Verschlussfolien während des Zuführens kollidieren, was die Verschlussfolien beschädigen oder zumindest verformen könnte. Dabei ist es weiter bevorzugt, wenn die Transporteinrichtung eine Schiene zum parallelen Ausrichten und Zuführen des Ausgießelements und der Verschlussfolien aufweist. Durch die Schiene werden Berührungen der Verschlussfolien mit dem Ausgießelement während des Zuführens vermieden, was ebenfalls zu einer Beschädigung der Verschlussfolien führen könnte.In a further preferred manner, the directions of movement of the clamping devices and the transport device in the region of the transport device parallel to each other, thereby avoiding that pouring elements collide with sealing films during feeding, which could damage or at least deform the sealing films. It is further preferred if the transport device is a rail for parallel alignment and feeding the Spout and the closure films. The rail avoids contact of the closure foils with the pouring element during feeding, which could also damage the closure foils.

Um die Bewegung der Transporteinrichtung und die der Zuführeinrichtung in Abhängigkeit voneinander steuern zu können, ist in weiterer Ausgestaltung der Erfindung vorgesehen, einen Sensor zum Erfassen eines an der Transporteinrichtung eintreffenden Ausgießelements vorzusehen.In order to be able to control the movement of the transport device and that of the feed device as a function of one another, in a further embodiment of the invention it is provided to provide a sensor for detecting a pouring element arriving at the transport device.

Insbesondere für den Fall, dass bandförmiges Material für die Verschlussfolien verwendet wird, ist es bevorzugt, dass die Taktfördereinrichtung zwei parallel zueinander angeordnete Förderwalzen aufweist. Dies ermöglicht einerseits eine genaue Positionierung des Bandmaterials und stellt andererseits einen geringen konstruktiven Aufwand dar. Als Bandmaterial wird bevorzugt Aluminiumfolie verwendet.In particular, in the case where ribbon-shaped material is used for the sealing sheets, it is preferable that the clock conveying means has two conveying rollers arranged parallel to each other. On the one hand, this enables accurate positioning of the strip material and, on the other hand, represents little constructional effort. The strip material used is preferably aluminum foil.

  • Zuführen von Bandmaterial,
  • Stanzen von Verschlussfolien aus dem Bandmaterial,
  • Fördern und Vereinzeln der Verschlussfolien,
  • Fixieren der Verschlussfolie in einer Klemmeinrichtung, die sich in einer Aufnahmeposition befindet,
  • Zuführen der Verschlussfolie von der Aufnahmeposition in eine Schweißposition,
  • Transport einer Verbundpackung mit einem Ausgießelement in den Bereich der Schweißposition,
  • Befestigen der Verschlussfolie am Ausgießelement mittels einer Schweißeinrichtung und Freigeben der Verschlussfolie durch die Klemmeinrichtung.
Procedurally, the solution of the task by the following steps:
  • Feeding strip material,
  • Punching closure foils from the strip material,
  • Conveying and separating the closure foils,
  • Fixing the sealing film in a clamping device, which is in a receiving position,
  • Feeding the sealing film from the receiving position to a welding position,
  • Transport of a composite packing with a pouring element in the area of the welding position,
  • Attaching the sealing foil to the pouring element by means of a welding device and releasing the sealing foil by the clamping device.
