Abstract

The device has clamps (7a, 7b) provided to circle a conveyor belt (6) on a path, where the path is identical for both the clamps. The clamps are respectively connected with a pair of traction units (13, 14). The clamps descend laterally downward before a third clamp that is behind the conveyor belt, where packages (G1, G2) are laid at the clamps (7a, 7b) that are accelerated in a short-run manner. The packages are assembled from a number of packaged products (P) such as beverages or flour packed in bags. An independent claim is also included for a method for stamping a number of packages in a foil.

Description

Die Erfindung betrifft eine Einrichtung und ein Verfahren zum Einschlagen von aus mehreren verpackten Produkten zusammengestellten Gebinden in Folie mit einem in Transportrichtung umlaufend angetriebenen, endlosen Transportband, auf das die Gebinde aufsetzbar sind, einer über das Transportband zugeführten Folie, einem ersten vor einem ersten aufgesetzten Gebinde in Transportrichtung mit der Geschwindigkeit des Transportbandes umlaufenden ersten Bügel, an dem das erste Gebinde anliegt, mindestens einem zweiten vor einem zweiten aufgesetzten Gebinde in Transportrichtung mit der Geschwindigkeit des Transportbandes umlaufenden zweiten Bügel, und mit einem unterhalb der zugeführten Folie angeordneten, mit höherer Geschwindigkeit als das Transportband angetriebenen dritten Bügel, der auf einer Bahnkurve das Transportband umrundet und auf seiner Bahnkurve oberhalb des Transportbandes die Folie um das am ersten Bügel anliegende Gebinde herumzieht.The invention relates to a device and a method for wrapping composed of several packaged products containers in foil with a circumferentially driven in the transport direction, endless conveyor belt to which the containers are placed, a supplied via the conveyor belt, a first placed in front of a first container in the transport direction with the speed of the conveyor belt rotating first bracket to which the first container is present, at least a second before a second patch container in the transport direction with the speed of the conveyor belt circulating second bracket, and arranged with a below the supplied film, with a higher speed than the conveyor belt driven third bracket, which circumscribes the conveyor belt on a trajectory and pulls on its trajectory above the conveyor belt, the film around the adjacent to the first bracket container.

Eine solche Einrichtung ist beispielsweise aus der DE 42 07 725 A1 bekannt.Such a device is for example from the DE 42 07 725 A1 known.

Einzeln verpackte Produkte, wie beispielsweise in Kartons eingefüllte Getränke oder in Tüten verpacktes Mehl oder dergleichen werden zum besseren Transport anschließend zu größeren Gebinden zusammengefasst. Hierzu werden die Produkte in einer Verpackungsmaschine zusammen gefördert und durch entsprechende Steuerung der Transportbänder zu Gruppen gewünschter Größe zusammengefasst. Ein solches Gebinde kann dann beispielsweise durch Einfüllen mehrerer Produkte in eine Verpackung aus Karton oder durch Einwickeln in Folie erfolgen, die anschließend geschrumpft wird, so dass das Gebinde stabil wird.Individually packaged products, such as drinks filled in cartons or flour packaged in bags or the like, are subsequently added for better transportation summarized to larger containers. For this purpose, the products are conveyed together in a packaging machine and summarized by appropriate control of the conveyor belts to groups of desired size. Such a container can then take place, for example, by filling a plurality of products in a cardboard packaging or by wrapping in film, which is then shrunk so that the container is stable.

Aus der US 2002/0189204 A1 ist ein Verfahren zum Einschlagen von Produkten mit einer Schrumpffolie und eine Vorrichtung hierzu bekannt.From the US 2002/0189204 A1 is a method for wrapping products with a shrink film and an apparatus known thereto.

Kleinere Verpackungen, insbesondere Getränkekartons, die keinen Quader sondern einen Polyeder bilden, müssen in Umkartons einfüllt werden, da ihre Aufstandsfläche so klein ist, dass sie vielfach beim Einschlagen in Folie umfallen, was dann zu einem Produktionsstillstand führt, weil das gesamte Gebinde, das die umgefallene Packung enthält, vom Band geräumt werden muss, was die Produktionskosten deutlich erhöht.Smaller packaging, especially beverage cartons, which do not form a cuboid but a polyhedron, must be filled in cartons, since their footprint is so small that they often fall over when wrapping in foil, which then leads to a production stoppage, because the entire container, the which must be evacuated from the belt, which significantly increases the cost of production.

Um das Umfallen der Produkte zu verhindern, ist bei der Einrichtung nach der DE 42 07 725 A1 vorgesehen, dass vor und hinter einem Gebinde Abstützbügel an die Produkte angelegt werden. Dann wird das Gebinde mittels eines dritten Bügels zusammen mit den Abstützbügeln mit Folie umwickelt. Wenn der Wickelvorgang beendet ist, werden die Bügel seitlich herausgezogen, bevor der Schrumpfvorgang beginnt.In order to prevent the fall of the products is in the device after the DE 42 07 725 A1 provided that before and behind a container Abstützbügel be applied to the products. Then the container is wrapped by means of a third bracket together with the Abstützbügeln with foil. When the winding process is completed, the straps are pulled out laterally before the shrinking process begins.

Mit dieser Ausgestaltung kann das Umfallen verhindert werden. Damit die Bügel aber seitlich herausgezogen werden können, ist eine entsprechend längere Förderstrecke notwendig. Außerdem sind Störungen nicht ausgeschlossen, wenn die Folie zu eng gewickelt wird und dadurch die auf die Bügel einwirkenden Reibungskräfte hoch sind. Durch die entsprechend lockere Wickelung ist der Folienbedarf pro Gebinde hoch. Außerdem können nur zwei Einschlagbahnen unmittelbar nebeneinander angeordnet werden, weil seitlich neben jeder Bahn ausreichend Platz verbleiben muss, um die Abstützbügel herausfahren zu können.With this configuration, the falling over can be prevented. So that the brackets can be pulled out laterally, a correspondingly longer conveying distance is necessary. In addition, disturbances are not excluded if the film is wound too tightly and thereby the frictional forces acting on the stirrups are high. Due to the correspondingly loose winding, the film requirement per container is high. In addition, only two lanes can be arranged directly next to each other, because laterally next to each lane must remain sufficient space to drive out the Abstützbügel can.

Die nachveröffentlichte DE 10 2005 051 027 A1 offenbart eine Einrichtung und ein Verfahren zum Einschlagen eines Gebindes mit Folie. Die zu einem Gebinde zusammengefassten Produkte werden mit ihrer Aufstandsfläche auf die Folie aufgelegt und stützen sich gegen einen ersten umlaufenden Bügel ab, der mit derselben Geschwindigkeit wie das Transportband und die Folie umläuft und dadurch wirkungsvoll verhindert, dass einzelne Produkte während des Förderprozesses umfallen. Ein zweiter Bügel umwickelt das Gebinde mit der Folie und beide Bügel tauchen auf ihren Bahnkurven am Ende des Transportbandes unter dieses ab. Das dann in Folie geschlagene Gebinde kann übergeben werden auf ein dem Transportband nachfolgend angeordnetes Band, das das Gebinde in einen Schrumpfofen fördert, in dem die Folie geschrumpft wird, so dass das Gebinde stabil transportierbar wird.The post-published DE 10 2005 051 027 A1 discloses a device and method for wrapping a package with foil. The combined into a container Products are placed with their footprint on the film and are supported against a first circumferential strap, which revolves at the same speed as the conveyor belt and the film and thereby effectively prevents individual products fall over during the conveying process. A second strap wraps the container with the film and both brackets dive on their trajectories at the end of the conveyor belt under this. The then wrapped in foil container can be passed to a belt arranged below the conveyor, which promotes the container in a heat-shrink oven, in which the film is shrunk so that the container is stably transported.

Von dieser Problemstellung ausgehend sollen die gattungsgemäße Einrichtung und das beschriebene Verfahren so verbessert werden, dass das Einschlagen der Gebinde in Folie vereinfacht wird und der Verfahrensablauf zeitlich optimiert wird.Based on this problem, the generic device and the method described should be improved so that the wrapping of the container in film is simplified and the procedure is optimized in time.

Zur Problemlösung zeichnet sich eine gattungsgemäße Einrichtung durch folgende Merkmale aus:

  • der erste und der zweite Bügel umrunden das Transportband auf einer Bahnkurve,
  • die Bahnkurve für den ersten Bügel und den zweiten Bügel ist identisch,
  • der erste Bügel steht mit einem ersten Antrieb und der zweite Bügel steht mit einem zweiten Antrieb in Verbindung,
  • die Bügel, an denen die Gebinde anliegen, tauchen hinter dem Transportband zeitlich vor dem dritten Bügel nach unten ab, und
  • werden hierzu zumindest kurzfristig beschleunigt.
To solve the problem, a generic device is characterized by the following features:
  • the first and second brackets circle the conveyor belt on a trajectory,
  • the trajectory for the first stirrup and the second stirrup is identical,
  • the first bracket is connected to a first drive and the second bracket is connected to a second drive,
  • the stirrups on which the containers are located dive down behind the conveyor belt before the third stirrup, and
  • will be accelerated, at least in the short term.

Verfahrensmäßig erfolgt die Lösung des Problems durch folgende Schritte:

  • Antreiben eines ersten Bügels entlang einer ersten Bahnkurve, die um ein mit einer Transportgeschwindigkeit in Transportrichtung angetriebenes Transportband verläuft, in Bezug auf die Transportrichtung mit Transportgeschwindigkeit,
  • Antreiben eines zweiten Bügels entlang der ersten Bahnkurve,
  • Antreiben mindestens eines dritten Bügels entlang einer, von der ersten Bahnkurve unterschiedlichen zweiten Bahnkurve, die um das angetriebene Transportband verläuft, mit einer Geschwindigkeit, die größer ist als die Transportgeschwindigkeit,
  • Auflegen einer Folienbahn auf den vorderen Bereich des Transportbandes vor dem ersten Bügel und Mitführen der Folienbahn mit Transportgeschwindigkeit,
  • Aufsetzen eines ersten Gebindes auf die mit dem Transportband transportierte Folienbahn mit Transportgeschwindigkeit derart, dass das Gebinde an dem ersten Bügel anliegt,
  • Anheben der Folienbahn von dem Transportband mittels des mindestens einen dritten Bügels über das Gebinde hinweg,
  • Vorbeiführen des dritten Bügels mit der angehobenen Folienbahn über das Gebinde,
  • Beschleunigen des ersten Bügels am Ende des Transportbandes,
  • Absenken des ersten Bügels hinter dem Transportband,
  • Absenken der Folienbahn auf das Transportband mittels des mindestens einen dritten Bügels hinter dem ersten Gebinde am Ende des Transportbandes,
  • Absenken des mindestens einen dritten Bügels hinter dem Transportband,
  • Zurückführen beider Bügel unterhalb des Transportbandes auf ihren Bahnkurven,
  • Abbremsen des ersten Bügels auf die Transportgeschwindigkeit,
Procedurally, the solution to the problem is through the following steps:
  • Driving a first strap along a first trajectory, which extends around a conveyor belt driven at a transport speed in the transport direction, with respect to the transport direction at transport speed,
  • Driving a second strap along the first trajectory,
  • Driving at least one third strap along a second trajectory different from the first trajectory, which runs around the driven conveyor belt, at a speed that is greater than the transport speed,
  • Placing a film web on the front region of the conveyor belt in front of the first bail and carrying the film web at transport speed,
  • Placing a first container on the transported with the conveyor belt web at transport speed such that the container is applied to the first bracket,
  • Lifting the film web from the conveyor belt by means of the at least one third bracket over the container,
  • Passing the third strap with the raised foil web over the container,
  • Accelerating the first strap at the end of the conveyor belt,
  • Lowering the first bracket behind the conveyor,
  • Lowering the film web onto the conveyor belt by means of the at least one third bracket behind the first container at the end of the conveyor belt,
  • Lowering the at least one third bracket behind the conveyor belt,
  • Returning both stirrups below the conveyor belt on their trajectories,
  • Braking the first bracket to the transport speed,

Durch diese Ausgestaltung werden die zu dem Gebinde zusammengefassten Produkte mit ihrer Aufstandsfläche auf die Folie aufgelegt und stützen sich gegen den ersten Bügel bzw. den zweiten Bügel ab, der mit derselben Geschwindigkeit wie das Transportband und die Folie umläuft und dadurch wirkungsvoll verhindert, dass einzelne Produkte während des Förderprozesses umfallen. Der dritte Bügel umwickelt das Gebinde mit der Folie und beide Bügel tauchen auf ihren Bahnkurven am Ende des Transportbandes unter dieses ab. Das dann in Folie eingeschlagene Gebinde kann übergeben werden auf ein dem Transportband nachfolgend angeordnetes Band, das das Gebinde in einen Schrumpfofen fördert, in dem die Folie geschrumpft wird, so dass das Gebinde stabil transportierbar wird. Dadurch, dass die beiden Bügel, an denen die Gebinde anliegen von jeweils einem eigenen Antrieb angetrieben werden, und die Antriebe voneinander unabhängig ansteuerbar sind, können diese Bügel, wenn sie das Ende des Transportbandes erreicht haben, beschleunigt werden, bevor sie hinter dem Transportband nach unten abtauchen. Dadurch kann die von der Länge des Transportbandes bestimmte Transportstrecke reduziert werden, weil die Beschleunigung des Haltebügels (erster bzw. zweiter Bügel) erfolgt, bevor dieser von dem Folieneinschlagbügel (dritter Bügel) überholt wird. Dadurch, dass der erste und der zweite Bügel voneinander unabhängig angetrieben werden, können unterschiedlich große Gebinde bzw. Produkte auf der Anlage gefahren werden.As a result of this configuration, the products combined with the container are placed on the film with their contact surface and are supported against the first bracket or the second bracket, which revolves at the same speed as the conveyor belt and the film and thereby effectively prevents individual products fall over during the funding process. The third bracket wraps the container with the film and both brackets dive on their trajectories at the end of the conveyor belt under this. The pack then wrapped in foil can be transferred to a belt arranged downstream of the conveyor belt, which conveys the container into a shrink oven, in which the film is shrunk so that the container is stably transported. Due to the fact that the two stirrups against which the containers abut are each driven by a separate drive, and the drives can be controlled independently of one another, these stirrups, when they reach the end of the conveyor belt, can be accelerated before moving behind the conveyor belt dive down. As a result, the transport distance determined by the length of the conveyor belt can be reduced because the acceleration of the holding bracket (first or second bracket) takes place before it is overtaken by the film wrapping bracket (third bracket). The fact that the first and the second bracket are driven independently of each other, different sized containers or products can be driven on the system.

Vorzugsweise sind zum Antrieb des ersten und zweiten Bügels jeweils ein Servomotor vorgesehen. Auch der dritte Bügel kann durch einen eigenen Servomotor angetrieben werden.Preferably, in each case a servomotor are provided for driving the first and second bracket. Also, the third bracket can be driven by its own servo motor.

Zumindest der erste und zweite Bügel sind vorzugsweise an zwei beidseitig neben dem Transportband verlaufenden Zugmittel, die insbesondere Ketten sein können, befestigt. Dadurch ist eine parallele Lagefixierung und Führung der Bügel gewährleistet.At least the first and second brackets are preferably attached to two traction means running on both sides next to the conveyor belt, which may be chains in particular. As a result, a parallel position fixing and guiding the bracket is guaranteed.

Vorzugsweise ist in Transportrichtung T vor dem Transportband eine Folienschneidvorrichtung angeordnet. Dadurch wird sichergestellt, dass die von der Rolle zuführbare Folienbahn auf die zum Einschlagen des Gebindes notwendige Länge zugeschnitten wird, nachdem der zweite Bügel die Folienbahn anhebt, was das weitere Transportieren und Einschlagen erleichtert.Preferably, a film cutting device is arranged in the transport direction T in front of the conveyor belt. This ensures that the film web that can be fed from the roll is cut to the length necessary for wrapping the bundle after the second bow lifts the film web, which facilitates further transport and wrapping.

Die Folienschneideinrichtung ist bevorzugt in einer Ebene unterhalb des Transportbandes angeordnet. Ebenfalls in einer Ebene unterhalb des Transportbandes ist vorzugsweise die die Folie aufnehmende Rolle gelagert.The film cutting device is preferably arranged in a plane below the conveyor belt. Also in a plane below the conveyor belt, the film receiving roller is preferably stored.

Die in Folie eingeschlagenen Gebinde werden vorzugsweise in einer dem Transportband nachgeordneten Schrumpfeinrichtung im Durchlauf geschrumpft.The wrapped in foil containers are preferably shrunk in a conveyor belt downstream shrinking device in the flow.

Mit Hilfe einer Zeichnung soll ein Ausführungsbeispiel der Erfindung nachfolgend näher beschrieben werden.With the aid of a drawing, an embodiment of the invention will be described in more detail below.

Die in Figur 1a dargestellte Verpackungsmaschine arbeitet vereinfacht erläutert wie folgt:In the FIG. 1a illustrated packaging machine works simplified as follows:

Aus einem hier nicht näher dargestellten Produktionsprozess werden die Produkte P hintereinander der Verpackungsmaschine zugeführt. Im ersten Bereich I werden die Produkte P um 90° gedreht und dann aus einem aus vier oder mehr Produkten P bestehenden Gebinde Gi zusammengefasst. Im Bereich II wird das Gebinde Gi über eine Greif- und Drehvorrichtung 1 ergriffen, auf eine Transportgeschwindigkeit vT beschleunigt, erneut um 90° gedreht und am Ende des Bereiches II auf die im Bereich III angeordnete Folieneinschlageinrichtung 2 übergeben. Hier wird das Gebinde Gi in Folie 5 eingeschlagen und anschließend über eine kurze Rollenbahn an ein Transportband 12 übergeben, das das Gebinde G in einem im Bereich IV angeordneten Schrumpfofen 3 transportiert, wo es im Durchlauf unter Hitzewirkung geschrumpft wird.From a production process, not shown here, the products P are successively fed to the packaging machine. In the first area I, the products P are rotated by 90 ° and then combined from a container G i consisting of four or more products P. In region II, the container G i is gripped by a gripping and rotating device 1, accelerated to a transport speed v T , again rotated by 90 ° and transferred at the end of region II to the film inserting device 2 arranged in region III. Here, the container G i is wrapped in foil 5 and then passed over a short roller conveyor to a conveyor belt 12, which arranged the container G in a region IV Shrinking furnace 3 transports, where it is shrunk in the passage under heat effect.

Unterhalb des Gestells der Verpackungsanlage ist eine Rolle 4 gelagert, auf die eine Folienbahn 5 aufgewickelt ist. Die Folienbahn 5 wird über verschiedene Umlenk- und Spannvorrichtungen, die hier nicht näher erläutert werden sollen, in Richtung des mit Transportgeschwindigkeit vT umlaufenden Transportbandes 6 der in Folienschlageinrichtung 2 gefördert. Vor dem Transportband 6 ist eine Folienschneidvorrichtung 9 angeordnet, mit der die Folienbahn 5 in Längen getrennt wird, die notwendig sind, um ein Gebinde G im Bereich III in Folie einzuschlagen.Below the frame of the packaging system, a roller 4 is mounted, on which a film web 5 is wound. The film web 5 is conveyed by means of various deflection and tensioning devices, which will not be explained in more detail here, in the direction of the transport belt 6 circulating at the transport speed v T in the film striking device 2. Before the conveyor belt 6, a film cutting device 9 is arranged, with which the film web 5 is separated into lengths that are necessary to beat a container G in the area III in foil.

Die Folieneinschlagvorrichtung 2 besteht im Wesentlichen aus dem in Transportrichtung T umlaufend angetriebenen Transportband 6, das über eine Mehrzahl hier nicht einzeln bezeichneter Umlenk- und Spannrollen geführt ist. Ein erster, auf einer ersten Bahnkurve B1 quer (in Zeichenebene) über das Transportband 6 ragender Bügel 7a wird über einen ersten Servomotor 18 angetrieben. Ein zweiter Bügel 7b wird über einen zweiten, hier nicht näher dargestellten Servomotor angetrieben. Die beiden Servomotoren 18 sind voneinander unabhängig ansteuerbar. Die Bügel 7a, 7b werden an parallel neben dem Transportband 6 angeordneten Ketten 13, 14; 15, 16 geführt, die auf einer identischen Bahnkurve B1 laufen. Die Bahnkurven B1 sind in vertikaler Richtung identisch. In horizontaler Richtung verlaufen sie parallel zueinander.The film wrapping device 2 consists essentially of the transport belt 6 driven peripherally in the transporting direction T, which is guided over a plurality of deflecting and tensioning rollers which are not individually designated here. A first, on a first trajectory B 1 transversely (in drawing plane) on the conveyor belt 6 projecting bracket 7a is driven by a first servo motor 18. A second bracket 7b is driven by a second, not shown here servomotor. The two servomotors 18 are independently controllable. The brackets 7a, 7b are arranged on parallel next to the conveyor belt 6 chains 13, 14; 15, 16 out, which run on an identical trajectory B 1 . The trajectories B 1 are identical in the vertical direction. In the horizontal direction, they run parallel to each other.

Auf einer zweiten Bahnkurve B2 werden zwei ebenfalls quer (in Zeichenebene) über das Transportband 6 ragende Bügel 8a, 8b mit einer Geschwindigkeit v2 angetrieben, die bezogen auf die Transportrichtung T größer ist als die Transportgeschwindigkeit vT mit dem das Transportband 6 umläuft. Der unterschiedliche Verlauf der Bahnkurven B1, B2 oberhalb und unterhalb des Transportbandes 6 ist den Figuren 3a bis e bzw. 4a bis e entnehmbar.On a second trajectory B 2 , two likewise transversely (in drawing plane) on the conveyor belt 6 projecting bracket 8 a, 8 b driven at a speed v 2 , which is relative to the transport direction T greater than the transport speed v T with which the conveyor belt 6 rotates. The different course of the trajectories B 1 , B 2 above and below the conveyor belt 6 is the FIGS. 3a to e respectively. 4a to e removable.

Die Folienbahn 5 wird in Richtung auf das Transportband 6 zugeführt, in der Schneidvorrichtung 9 geschnitten und ihr freies Ende über die diversen Rollen 10 dann auf den Anfang des Transportbandes 6 zugefördert und hier auf das Transportband 6 aufgelegt, von dem es ergriffen und mit Transportgeschwindigkeit vT mitgezogen wird. Über die Greif- und Drehvorrichtung 1 wird das zuvor auf Transportgeschwindigkeit vT beschleunigte Gebinde G1 auf die am Anfang des Förderbandes 6 liegende Folienbahn 5 aufgestellt, wobei es am Bügel 7a, der zu diesem Zeitpunkt ebenfalls am Anfang des Förderbandes 6 auf seiner Bahnkurve B1 läuft und mit Transportgeschwindigkeit vT angetrieben wird, anliegt. Das Gebinde G1 wird dann am Bügel 7a anliegend mit Transportgeschwindigkeit vT weitergeführt (vgl. Figur 3b). Der auf seiner Bahnkurve B2 mit höherer Geschwindigkeit v2 angetriebene Bügel 8a tritt in vertikaler Richtung vor dem Transportband 6 nach oben vorbei, hebt dabei die Folie 5 an und zieht sie entlang der Bahnkurve B2 um das Gebinde G1 herum. Am Ende des Einschlagvorganges (vgl. Figuren 3c, 4c) gelangt das Gebinde G1 in Eingriff mit dem Förderer 11, der die Stützfunktion übernimmt, so dass der Bügel 7a hinter dem Transportband 6 nach unten auf seiner Bahnkurve B1 zurückgeführt werden kann, dabei wird der Bügel 7a mittels des Servomotors 18 beschleunigt, um sicherzustellen, dass er nicht vom Bügel 8a eingeholt wird. Das Gebinde G1 wird weitertransportiert, bis auch der zweite Bügel 8a unter das Transportband 6 taucht, wobei ein Teil der Folie 5 dann über den Aufstandsbereich des Gebindes G1 hervorsteht. Das Gebinde G1 wird dann mittels des Förderers 11 von dem Transportband 6 auf das Transportband 12 übergeben, wobei der überstehende Teil der Folie 5 um den Aufstandsbereich des Gebindes G1 herumgezogen wird und das Gebinde G1 dann in den Schrumpfofen 3 überführt wird.The film web 5 is fed in the direction of the conveyor belt 6, cut in the cutting device 9 and then fed their free end on the various rollers 10 to the beginning of the conveyor belt 6 and placed here on the conveyor belt 6, from which it is taken and with transport speed v T pulled along becomes. About the gripping and rotating device 1, the previously accelerated at transport speed v T container G 1 is placed on the lying at the beginning of the conveyor belt 6 film web 5, wherein it at the same time on the bracket 7a at the beginning of the conveyor belt 6 on its trajectory B. 1 is running and with transport speed v T is driven, is applied. The container G 1 is then continued on the bracket 7a adjacent transport speed v T (see. FIG. 3b ). The on his trajectory B 2 at a higher speed v 2 driven bracket 8a passes in the vertical direction in front of the conveyor belt 6 upwards over, lifts the film 5 and pulls them along the trajectory B 2 to the container G 1 around. At the end of the wrapping process (cf. Figures 3c . 4c ), the container G 1 engages with the conveyor 11, which takes over the support function, so that the bracket 7a can be returned behind the conveyor belt 6 down on its trajectory B 1 , while the bracket 7a is accelerated by the servo motor 18 to ensure that it is not overtaken by the bracket 8a. The container G 1 is transported further, until the second bracket 8a dives under the conveyor belt 6, wherein a portion of the film 5 then protrudes beyond the contact area of the container G 1 . The container G 1 is then transferred by the conveyor 11 from the conveyor belt 6 to the conveyor belt 12, wherein the protruding portion of the film 5 is pulled around the uprising portion of the container G 1 and the container G 1 is then transferred to the consolidation furnace. 3

Das Schneiden der Folie 5 erfolgt vorzugsweise, nachdem der Bügel 8a die Folie 5 vom Transportband 6 angehoben hat, und zwar dann, wenn ausreichend Folie 5 abgezogen ist, um das Gebinde Gi vollständig einzuschlagen. Bei kleineren Gebinden ist es gleichwohl möglich, die Folie 5 vor dem Anheben durch den Bügel 8a, 8b zu schneiden. Sie wird dann durch die diversen Rollen 10 dem Transportband 6 zugeführt.The cutting of the film 5 is preferably carried out after the bracket 8a has lifted the film 5 from the conveyor belt 6, and that is when sufficient film 5 is peeled off to fully beat the container G i . For smaller containers, it is nevertheless possible to cut the film 5 before lifting by the bracket 8a, 8b. It is then fed through the various rollers 10 the conveyor belt 6.

Die Bügel 7a, 7b; 8a, 8b laufen unterhalb des Transportbandes 6 nach vorn zum Anfang zurück und das nächste Gebinde Gi kann vorn Bügel 7a gestützt und - wie vorstehend beschrieben - mittels des Bügels 8a in Folie eingeschlagen werden. Im Bereich unterhalb des Transportbandes 6 wird der zuvor zum rechtzeitigen Abtauchen beschleunigte Bügel 7a wieder soweit verzögert, dass er vor das nächste Gebinde G2 wieder mit der Transportgeschwindigkeit vT auftauchen kann, so dass sich das Gebinde G2 anlegt. Die Gesamtzahl der Bügel 7a, 7b; 8a, 8b ist abhängig von der Länge des Transportbandes 6 und der Transportgeschwindigkeit vT, mit dem Ziel, eine möglichst hohe Taktzahl zu erreichen.The brackets 7a, 7b; 8a, 8b run back below the conveyor belt 6 forward to the beginning and the next container G i can be supported by the bracket 7a and - as described above - are beaten in foil by means of the bracket 8a. In the area below the conveyor belt 6 of the previously accelerated for timely descent bracket 7a is again delayed so far that he is in front of the next container G 2 can reappear with the transport speed v T , so that the container G 2 applies. The total number of brackets 7a, 7b; 8a, 8b is dependent on the length of the conveyor belt 6 and the transport speed v T , with the aim of achieving the highest possible number of cycles.

Dadurch, dass die Bügel 7a, 7b; 8a, 8b auf ihren Bahnkurven B1, B2 um das Transportband 6 herumlaufen, ist das Transportband 6 seitlich frei, so dass eine beliebige Anzahl von Transportbändern 6 zur Kapazitätserhöhung der Gesamtanlage unmittelbar parallel nebeneinander angeordnet und betrieben werden können und über eine hier nicht näher dargestellte Weiche die Gebinde Gi auf die einzelnen Bahnen dann verteilt werden.Characterized in that the bracket 7a, 7b; 8a, 8b on their trajectories B 1 , B 2 run around the conveyor belt 6, the conveyor belt 6 is laterally free, so that any number of conveyor belts 6 to increase the capacity of the entire system can be arranged and operated parallel to each other side by side and not closer here shown switch the containers G i are then distributed to the individual webs.

Um die Spalte S1, S2 zwischen den Transportbändern 6, 17 bzw. 6, 12 möglichst eng halten zu können, sind die Bahnkurven B1 und B2 an der Stelle, wo die Bügel 7a, 7b, 8a, 8b auftauchen bzw. abtauchen, identisch. Jeder Bügel 7a, 7b, 8a, 8b passiert also das Transportband in dieser Situation an demselben Punkt.In order to keep the gaps S 1 , S 2 between the conveyor belts 6, 17 and 6, 12 as narrow as possible, the trajectories B 1 and B 2 at the point where the bracket 7 a, 7 b, 8 a, 8 b appear or dive, identical. Each bracket 7a, 7b, 8a, 8b thus passes the conveyor belt in this situation at the same point.

Figur 2 zeigt, dass zwei aus mehreren parallel nebeneinander stehenden Produkten gebildeten Gebinde G1 nebeneinander geführt werden können. Unterhalb des Förderbandes 6 ist zu Beginn des Förderbandes eine hier nicht näher dargestellte Schneideinrichtung vorgesehen, die die Folie 5 in Transportrichtung T mittig trennt, so dass zwei Folienstreifen über die beiden Gebinde G1 geschlagen werden. FIG. 2 shows that two of several parallel juxtaposed products formed container G 1 can be performed side by side. Below the conveyor belt 6, a cutting device not shown here is provided at the beginning of the conveyor belt, which separates the film 5 in the transport direction T center, so that two film strips are beaten on the two containers G 1 .
