Description
Die vorliegende Erfindung betrifft eine Verpackungsmaschine mit einem Tänzer, einer Folienbremse, einem Klebetisch und/oder einer Folienrolle.The present invention relates to a packaging machine with a dancer, a film brake, a gluing table and / or a film roll.
Derartige Verpackungsmaschinen sind aus dem Stand der Technik bekannt. Siehe z.B.
Es war deshalb die Aufgabe der vorliegenden Erfindung, eine Verpackungsmaschine zur Verfügung zu stellen, die die Nachteile des Standes der Technik nicht aufweist.
Gelöst wird die Aufgabe mit einer Verpackungsmaschine gemäß Anspruch 1.Such packaging machines are known from the prior art. See eg
It was therefore the object of the present invention to provide a packaging machine which does not have the disadvantages of the prior art.
The problem is solved with a packaging machine according to
Die vorliegende Erfindung betrifft eine Verpackungsmaschine, bei der eine Unterfolienbahn, insbesondere eine Kunststofffolienbahn, die vorzugsweise eine Breite zwischen 200 mm und 1 m und mehr aufweist, von einer Vorratsrolle abgerollt und vorzugsweise intermittierend entlang der Verpackungsmaschine transportiert wird. In einer Formstation wird diese Unterfolienbahn dann zunächst erwärmt und mittels eines Tiefziehwerkzeugs werden Verpackungsmulden in die Unterfolienbahn geformt. In der Regel werden mehrere Verpackungsmulden, die in einem sogenannten Format angeordnet sind, gleichzeitig geformt und im Folgenden gleichzeitig entlang der Verpackungsmaschine transportiert. Nachfolgend wird jede Verpackungsmulde mit einem Verpackungsgut, insbesondere einem Lebensmittel, wie beispielsweise Wurst, Schinken oder Käse, befüllt und in einem nächsten Schritt in einer Siegelstation mit einer Oberfolie verschlossen, wobei die Oberfolie in der Regel an die Unterfolienbahn gesiegelt wird. Anschließend wird die so fertiggestellte Verpackung vereinzelt. Die Oberfolienbahn wird ebenfalls von einer Vorratsrolle abgerollt.The present invention relates to a packaging machine in which a lower film web, in particular a plastic film web, which preferably has a width between 200 mm and 1 m and more, is unrolled from a supply roll and preferably transported intermittently along the packaging machine. In a forming station, this sub-web is then first heated and by means of a thermoforming tool Molded packaging troughs in the lower film web. As a rule, several packaging troughs, which are arranged in a so-called format, are shaped simultaneously and subsequently transported simultaneously along the packaging machine. Subsequently, each packaging tray with a packaged, especially a food, such as sausage, ham or cheese, filled and sealed in a next step in a sealing station with a top film, the top film is usually sealed to the lower film web. Subsequently, the thus finished packaging is separated. The top film web is also unrolled from a supply roll.
Erfindungsgemäß ist stromabwärts von der jeweiligen Vorratsrolle bezogen auf die Transportrichtung der jeweiligen Folienbahn zumindest im Bereich der Oberfolienbahn, aber ggf. auch im Bereich der Unterfolienbahn ein Tänzer vorgesehen, der vorzugsweise zwei Rollen aufweist, die an einem Gestänge vorgesehen sind, das sich von einem Drehantrieb angetrieben um eine Drehachse dreht und dadurch eine gewisse Folienlänge speichert und/oder die gewünschte Spannung in der Folienbahn erzeugt. Der Tänzer eignet sich folglich als Materialspeicher, da die Abwicklung der Folienbahn von der Vorratsrolle mit einem unterschiedlichen Geschwindigkeitsprofil als der Vorschub der Folienbahn erfolgt.According to the invention, a dancer is provided downstream of the respective supply roll with respect to the transport direction of the respective film web at least in the region of the top film web, but possibly also in the region of the bottom film web, which preferably has two rollers which are provided on a linkage extending from a rotary drive driven rotates about a rotation axis and thereby stores a certain length of film and / or generates the desired tension in the film web. Consequently, the dancer is suitable as a material storage since the development of the film web from the supply roll takes place with a different velocity profile than the advance of the film web.
Ein Gestänge im Sinne der Erfindung ist jedes beliebige Bauteil, das beispielsweise aus Stangen, Rohren, Profilen und/oder Blechen und/oder Platten zusammengesetzt ist. Bei dem Gestänge kann es sich aber auch um ein urgeformtes Bauteil handeln, dass ggf. nachbearbeitet wird. An diesem Gestänge sind mindestens zwei drehbare, insbesondere nicht angetriebene Rollen angeordnet.A linkage in the context of the invention is any component which is composed for example of rods, tubes, profiles and / or sheets and / or plates. The linkage can also be a pre-formed component that may be reworked. At least two rotatable, in particular non-driven rollers are arranged on this linkage.
Vorzugsweise ist an dem Tänzer ein Mittel vorgesehen, mit dem die Winkelstellung des Gestänges erfasst wird. Dadurch weiß eine Steuerung, an die dieses Mittel angeschlossen ist, welche Folienbahnlänge sich in dem Tänzer befindet und/oder die Steuerung kann beispielsweise die Gradzahl errechnen, um die die Stellung des Gestänges verändert werden muss, um eine bestimmte Spannung in der Folie zu erzielen.Preferably, a means is provided on the dancer, with which the angular position of the linkage is detected. As a result, a controller to which this means is connected knows which length of film web is in the dancer and / or the controller can, for example, calculate the number of degrees by which the position of the linkage has to be changed in order to achieve a certain tension in the film.
Erfindungsgemäß ist der Tänzer, insbesondere das Gestänge, mit einem Drehantrieb versehen und/oder verbunden, der das Gestänge und damit die beiden Rollen gleichzeitig um die Drehachse des Gestänges dreht und dadurch die Speicherlänge der Folienbahn in dem Tänzer und/oder die Folienspannung verändert. Vorzugsweise handelt es sich bei dem Drehantrieb um einen pneumatischen Antrieb, einen Servo- oder einen Schrittmotor. Für den Fall, dass der Drehantrieb ein pneumatischer Antrieb ist, wird vorzugsweise der Druck in Abhängigkeit von der Winkelstellung des Gestänges angepasst. Dies kann beispielsweise durch ein Proportionalventil erfolgen. Ausgehend von einer Nullstellung fällt der Druck vorzugsweise ab und steigt dann bis zur Endstellung des Gestänges wieder an. Besonders bevorzugt entspricht der Druckverlauf einer Cosinus-Kurve, wobei der Druck besonders bevorzugt zu keinem Zeitpunkt null sein sollte.
Gemäß einer bevorzugten Ausführungsform der vorliegenden Erfindung ist mindestens eine Rolle des Tänzers, vorzugsweise alle Rollen des Tänzers, an ihren beiden gegenüberliegenden Enden gelagert. Dadurch ergibt sich eine gleichmäßigere Lastverteilung entlang der Rolle. Insbesondere wird deren Biegung zumindest vermindert und/oder über die Folienbreite weitgehend symmetrisch gestaltet, was insbesondere bei breiten Folienbahnen, vorzugsweise > 400 mm, von entscheidender Bedeutung ist, um über die gesamte Breite der Folienbahn, d.h. quer zu ihrer Transportrichtung einen möglichst konstanten und/oder zumindest symmetrischen Spannungsverlauf zu erzielen.
Vorzugsweise stützen sich beide Lager jeder Rolle an einer Wand, die sich auf einer Seite der Folienbahn befindet, ab. Dadurch ist der Bereich unter dem Tänzer frei verfügbar und kann eingesehen und, falls benötigt, bearbeitet werden.
Vorzugsweise ist der Tänzer, insbesondere das Gestänge vollständig eingehaust. Die Folienbahn gelangt durch Schlitze in das Gehäuse hinein bzw. aus dem Gehäuse heraus. Dadurch ist der Tänzer vor Spritzwasser, beispielsweise bei der Reinigung geschützt.
Besonders bevorzugt ist der umgebende Maschinenbereich, in dem der Tänzer angeordnet ist, vollständig eingehaust. Alternativ oder zusätzlich ist das Gehäuse so vorgesehen, dass nach Öffnen einer Zugangstür der ganze Tänzer, insbesondere jedoch das Gestänge frei zugänglich ist.
Vorzugsweise sind die Rollen, insbesondere deren Drehlager geerdet, so dass es zu keiner unerwünschten spontanen Entladung aufgrund von elektrostatischer Aufladung kommt. Die Drehlager sind vorzugsweise Wälzlager.According to the dancer, in particular the linkage, provided with a rotary drive and / or connected, which simultaneously rotates the linkage and thus the two rollers about the axis of rotation of the linkage and thereby changes the storage length of the film web in the dancer and / or the film tension. The rotary drive is preferably a pneumatic drive, a servo motor or a stepper motor. In the event that the rotary drive is a pneumatic drive, the pressure is preferably adjusted as a function of the angular position of the linkage. This can be, for example done by a proportional valve. Starting from a zero position, the pressure preferably drops and then rises again until the end position of the linkage. Particularly preferably, the pressure curve corresponds to a cosine curve, with the pressure particularly preferably not being zero at any time.
According to a preferred embodiment of the present invention, at least one roller of the dancer, preferably all the rollers of the dancer, is supported at its two opposite ends. This results in a more uniform load distribution along the roll. In particular, their bending is at least reduced and / or made largely symmetrical over the width of the film, which is particularly important for wide film webs, preferably> 400 mm, to over the entire width of the film web, ie transversely to its transport direction as constant as possible and /. or at least to achieve symmetrical voltage curve.
Preferably, both bearings of each roller are supported on a wall located on one side of the film web. As a result, the area under the dancer is freely available and can be viewed and, if necessary, edited.
Preferably, the dancer, in particular the linkage is completely enclosed. The film web passes through slots in the housing or out of the housing. As a result, the dancer is protected from splash water, for example during cleaning.
Particularly preferably, the surrounding machine area, in which the dancer is arranged, completely housed. Alternatively or additionally, the housing is provided so that after opening an access door, the whole dancer, but in particular the linkage is freely accessible.
Preferably, the rollers, in particular their pivot bearings are grounded, so that there is no undesirable spontaneous discharge due to electrostatic charge. The pivot bearings are preferably rolling bearings.
Gemäß einem weiteren bevorzugten Gegenstand der vorliegenden Erfindung ist bezogen auf die Transportrichtung der Ober- und der Unterfolienbahn, insbesondere jedoch der Oberfolienbahn stromabwärts von dem Tänzer eine Folienbremse vorgesehen, die insbesondere zur Positionierung der Oberfolienbahn auf der Unterfolienbahn benötigt wird, beispielsweise zur Positionierung von Druckmustern, die oftmals auf der Oberfolienbahn vorgesehen sind.According to a further preferred subject matter of the present invention, based on the transport direction of the upper and lower film webs, but in particular the upper film web downstream of the dancer, a film brake is provided which is required in particular for positioning the upper film web on the lower film web, for example for positioning printing patterns, which are often provided on the upper film web.
Vorzugsweise ist diese Folienbremse schwenkbar, insbesondere um eine vertikale Achse und/oder eine horizontale Achse schwenkbar, gelagert. Dadurch kann die Folienbremse von ihrer Ausrichtung im Produktionsstellung, d.h. quer zur Transportrichtung der Unterfolienbahn, in eine Position, beispielsweise parallel zu der Transportrichtung der Unterfolienbahn, geschwenkt werden, so dass dieser Bereich zu Inspektions- oder Bearbeitungszwecken zur Verfügung steht. Vorzugsweise ist gegenüberliegend von dem vertikalen Drehlager auf der anderen Seite der Folienbahn ein Verbindungsmittel, insbesondere ein Rastmittel vorgesehen, mit dem die Folienbremse in ihrer Produktionsstellung quer zur Transportrichtung der Unterfolienbahn fixiert werden kann. Dieses Verbindungsmittel wird vorzugsweise werkzeuglos betätigt. Weiterhin bevorzugt besteht die Folienbremse aus einem ersten und einem zweiten Teil, die miteinander verbunden sind, wobei zwischen dem ersten und dem zweiten Teil ein Spalt vorgesehen ist, durch den die Folienbahn, insbesondere die Oberfolienbahn, bei der Produktion läuft und im Bereich dessen ein Bremsmittel, beispielsweise ein aufblasbarer Schlauch, vorgesehen ist, mit dem der Transport der Oberfolie abgebremst werden kann, wodurch die Folienbahn gereckt wird. Vorzugsweise ist nun das zweite Teil drehbar, insbesondere um eine vertikale Drehachse, an dem ersten Teil gelagert oder umgekehrt. Dadurch kann, insbesondere zum Einfädeln der Folienbahn, das zweite Teil von dem ersten Teil weggedreht, die Folienbahn eingelegt und dann das zweite Teil wieder zurückgedreht und in einer Stellung parallel zu dem ersten Teil arretiert werden. Diese bevorzugte Ausführungsform der vorliegenden Erfindung erleichtert das Einfädeln der Folienbahn in die Folienbremse erheblich.Preferably, this film brake is pivotally mounted, in particular pivotable about a vertical axis and / or a horizontal axis. As a result, the film brake can be adjusted from its orientation in the production position, i. transverse to the transport direction of the lower film web, are pivoted to a position, for example, parallel to the transport direction of the lower film web, so that this area is available for inspection or processing purposes. Preferably, a connecting means, in particular a latching means is provided opposite the vertical pivot bearing on the other side of the film web, with which the film brake can be fixed in its production position transversely to the transport direction of the lower film web. This connecting means is preferably operated without tools. Further preferably, the film brake consists of a first and a second part, which are interconnected, wherein between the first and the second part, a gap is provided through which the film web, in particular the top film web, runs in production and in the region of a braking means , For example, an inflatable tube, is provided with which the transport of the top film can be slowed down, whereby the film web is stretched. Preferably, the second part is now rotatable, in particular about a vertical axis of rotation, mounted on the first part or vice versa. As a result, in particular for threading the film web, the second part is rotated away from the first part, the film web is inserted and then the second part is turned back again and locked in a position parallel to the first part. This preferred embodiment of the present invention greatly facilitates threading of the film web into the film brake.
Noch ein weiterer bevorzugter Gegenstand der vorliegenden Erfindung ist eine Verpackungsmaschine, die einen Schneid- und Klebetisch aufweist. Ein derartiger Schneid- und Klebetisch wird insbesondere bei einem Folienrollenwechsel benötigt, bei dem das Folienende der aufgebrauchten Folienrolle mit dem Anfang der neuen Folienrolle verbunden wird.
Vorzugsweise weist der Schneid- und Klebetisch mindestens eine, vorzugsweise mehrere Ausnehmungen auf, die an ein, insbesondere gemeinsames Vakuummittel angeschlossen sind. Durch dieses Vakuummittel werden die beiden zusammenzufügenden Folienbahnen auf dem Tisch fixiert und können entsprechend bearbeitet werden. Alternativ kann die Folienbahn auch mit Haftpads oder mit einem aufblasbaren Folienschlauch fixiert werden. Vorzugsweise sind die Ausnehmungen wahlweise sowie reversibel mit einem Ansaugmittel oder mit einem Blindstopfen bestückbar. Vorzugsweise weist das Ansaugmittel einYet another preferred object of the present invention is a packaging machine having a cutting and sticking table. Such a cutting and gluing table is particularly required in a film roll change, in which the film end of the used film roll is connected to the beginning of the new film roll.
Preferably, the cutting and bonding table has at least one, preferably a plurality of recesses, which are connected to a, in particular common vacuum means. By this vacuum means, the two film sheets to be joined are fixed on the table and can be processed accordingly. Alternatively, the film web can also be fixed with adhesive pads or with an inflatable film tube. Preferably, the recesses are selectively and reversibly equipped with a suction or with a blind plug. Preferably, the suction means
Lochblech auf. Mittels des Lochblechs kann das Vakuum auf die jeweilige Folienbahn übertragen werden. Ein Blindstopfen deckt die Ausnehmung ab, so dass in diesem Bereich keine Ansaugkraft auf die Folienbahn ausgeübt wird. Durch die Lage der Ausnehmungen bzw. der Einsätze der Ansaugmittel und der Blindstopfen ist es möglich, den Schneid- und Klebetisch beispielsweise an die Breite, aber auch an die Beschaffenheit der jeweiligen Folienbahn anzupassen, ohne dass unterschiedliche Schneid- und/oder Klebetische für die jeweilige Folienbahn zur Verfügung gestellt werden müssten. Vorzugsweise sind die Ausnehmungen entlang einer Linie, insbesondere äquidistant angeordnet. Besonders bevorzugt weist der Schneid- und Klebetisch mindestens zwei insbesondere parallele Reihen von Ausnehmungen auf. Alternativ oder zusätzlich zu dem Lochblech kann auch eine Schlitzdüse oder ein poröses, beispielsweise Sintermaterial, zum Einsatz kommen.
Vorzugsweise ist der Schneid- und Klebetisch schwenkbar und/oder leicht montierbar an der Verpackungsmaschine vorgesehen, was deren Zugänglichkeit verbessert. Vorzugsweise ist der Schneid- und Klebetisch stromaufwärts von dem Tänzer, bezogen auf die Transportrichtung der Folienbahn, angeordnet, besonders bevorzugt jedoch unmittelbar hinter der Folienrolle.Perforated sheet on. By means of the perforated plate, the vacuum can be transferred to the respective film web. A blind plug covers the recess, so that in this area no suction force is exerted on the film web. Due to the position of the recesses or the inserts of the suction means and the blind plug, it is possible to adapt the cutting and bonding table, for example, to the width, but also to the nature of the respective film web without different cutting and / or gluing tables for the respective Film web would have to be provided. The recesses are preferably arranged along a line, in particular equidistantly. Particularly preferably, the cutting and gluing table has at least two, in particular, parallel rows of recesses. As an alternative or in addition to the perforated plate, it is also possible to use a slot nozzle or a porous, for example sintered material.
Preferably, the cutting and gluing table is pivotally and / or easily mounted on the packaging machine, which improves their accessibility. Preferably, the cutting and sticking table is arranged upstream of the dancer, with respect to the transport direction of the film web, but particularly preferably immediately behind the film roll.
Noch ein weiterer bevorzugter Gegenstand der vorliegenden Erfindung ist eine Verpackungsmaschine, die Rollen aufweist, bei denen der Lagersitz mittels einer Laserschweißnaht mit dem Drehkörper der Rolle verbunden ist. Diese bevorzugte Ausführungsform der Erfindung hat den Vorteil, dass die Rollen erheblich weniger Wärmeverzug als Rollen gemäß dem Stand der Technik aufweisen. Trotzdem sind sie komplett wasserdicht.
Vorzugsweise verläuft die Oberfolienbahn stromaufwärts von der Siegelstation zumindest Abschnittsweise parallel zum Maschinenrahmen bzw. parallel zur Transportrichtung der Unterfolienbahn. Alternativ kann die Laufrichtung der Oberfolienbahn abschnittsweise auch um 90 Grad zum Maschinenrahmen angeordnet werden, wodurch beispielsweise besonders große und dadurch zumeist auch schwere Vorratsrollen verwendet werden können, die eine hohe Speicherkapazität von Folie beinhalten.Yet another preferred subject of the present invention is a packaging machine having rollers in which the bearing seat is connected by a laser weld to the rotating body of the roller. This preferred embodiment of the invention has the advantage that the rollers have considerably less heat distortion than rollers according to the prior art. Nevertheless, they are completely waterproof.
Preferably, the upper film web runs upstream of the sealing station at least in sections parallel to the machine frame or parallel to the transport direction of the lower film web. Alternatively, the direction of travel of the top film web sections can also be arranged by 90 degrees to the machine frame, which, for example, particularly large and therefore usually heavy supply rolls can be used, which include a high storage capacity of film.
