Abstract

The object to be wrapped is deposited on thin aluminium foil which extends over the mouth of a forming device comprising an annulus and a plurality of resilient blades each fixed at one end to the annulus and converging at their other, free ends towards a first half mould having a hemispherical cavity coaxial with the annulus. A push rod is advanced axially of the preforming device to push the object and the aluminium foil between the resilient blades, making the foil adhere to the leading surface of the object and effecting a first moulding of the aluminium foil around the trailing surface of the object. The partially wrapped object is expelled from the forming device the blades of which close to effect a second moulding of the aluminium foil over the trailing surface of the object, forming a rear projection in the form of a tail constituted by that part of the aluminium foil which does not adhere to the object. The object expelled from the forming device is transferred into the cavity of the first half-mould, while a second half-mould is having a hemispherical cavity facing the first half-mould is displaced axially of the first half-mould through the forming device so as to squash the rear projection of aluminium foil against the object.

Description

Die vorliegende Erfindung betrifft eine Vorrichtung zum Einwickeln eines runden, mit auf der Oberfläche verteilten, kleinen Erhöhungenn versehenen Gegenstandes gemäss dem Oberbegriff des Anspruchs 1. Aus der US-A-2 915 861 ist es bekannt, mittels einer solchen Vorrichtung kugelige Gegenstände, wie eine Frucht, mit Papier, und insbesondere Gewebepapier einzuwickeln. Hierzu wird dieses Papier auf eine ringförmig angeordnete Schar von Lamellen gelegt und auf dieses Papier dann der einzuwickelnde kugelige Gegenstand. Mittels eines Stempels wird dann dieser kugelige Gegenstand zusammen mit dem Papierdurch die Lamellenscharauf eineAufnahme gestossen,wobei das überstehende Papier durch die Lamellen gerafft wird.The present invention relates to a device for wrapping a round object provided with small elevations distributed on the surface according to the preamble of claim 1. From US-A-2 915 861 it is known to use such a device to produce spherical objects, such as Fruit, wrapped with paper, and especially tissue paper. For this purpose, this paper is placed on an array of lamellae arranged in a ring, and the spherical object to be wrapped is then placed on this paper. This spherical object together with the paper is then pushed onto a receptacle by means of a stamp, the excess paper being gathered by the lamellae.

Aus der GB-A-673 995 ist es bekannt, das schwanzförmige Anhängsel eines Verpackungsmaterials an den Gegenstand anzudrücken, was jedoch nicht durch ein entsprechend geformtes Werkzeug, sondern durch den nachfolgenden Gegenstand selbst erfolgt.From GB-A-673 995 it is known to press the tail-shaped appendage of a packaging material onto the object, but this is not done by an appropriately shaped tool, but by the subsequent object itself.

Bekannt sind Verfahren zum Einwickeln von glatten, runden Gegenständen in Alufolie. Solche Verfahren sind im allgemeinen bei runden Gegenständen mit kleinen, auf der Oberfläche verteilten Erhöhungen nicht anwendbar. In einem charakteristischen Anwendungsbeispiel besteht der runde Gegenstand aus einer runden Süssware, die mit einer gehackte Nüsse enthaltenden Schokoladenmasse überzogen ist. In diesem Fall würde die Anwendung der Verfahren zum Einwickeln von glatten, runden Produkten die Oberfläche der Süssware beschädigen, wodurch sich der ästhetische Gesamteindruck des Produktes verschlechtert.Methods for wrapping smooth, round objects in aluminum foil are known. Such methods are generally not applicable to round objects with small ridges distributed over the surface. In a characteristic application example, the round object consists of a round confectionery which is coated with a chocolate mass containing chopped nuts. In this case, the application of the methods for wrapping smooth, round products would damage the surface of the confectionery, thereby worsening the overall aesthetic impression of the product.

Daher musste man zum Einwickeln solcher Produkte bisher manuelle Verpackungsverfahren oder ziemlich komplizierte und sowohl zeitlich als auch kostenmässig aufwendige automatische Verfahren anwenden.For this reason, it has previously been necessary to use manual packaging processes or rather complicated automatic processes which are both time-consuming and costly to wrap such products.

Aufgabe der Erfindung ist es, eine Vorrichtung zum Einwickeln eines runden, mit kleinen, auf der Oberfläche verteilten Erhöhungen versehenen Gegenstandes in Alufolie zu schaffen, mit der das Einwickeln schnell und einfach durchzuführen ist, ohne den Gegenstand und/oder die Alufolie zu beschädigen.The object of the invention is to provide a device for wrapping a round object provided with small elevations distributed on the surface in aluminum foil, with which the wrapping can be carried out quickly and easily without damaging the object and / or the aluminum foil.

Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass die Aufnahme einen auf den Stempel zu gerichteten halbkugeligen Hohlraum aufweist, dass koaxial um den Stössel ein Stempel angeordnet ist, dessen nach unten gerichtetes Ende eine - abgesehen vom Stösseidurchtritt - halbkugelige Höhlung aufweist, und dass der Stössei und der Stempel derart gesteuert sind, dass letzterer beim Absenken des Stössels zunächst hinter diesem zurückbleibt und nach erfolgtem Durchdrücken des einzuwickelnden Gegenstandes durch die Formvorrichtung relativ zum Stössel so weit abgesenkt wird, dass sich der Stempel und die Aufnahme berühren und somit ihre Hohlräume zur Kugelform ergänzen, in welche der Stössel nicht eindringt.According to the invention, this object is achieved in that the receptacle has a hemispherical cavity that is directed toward the stamp, that a stamp is arranged coaxially around the plunger, the end of which is directed downward and has a hemispherical hollow, aside from the impact passage, and that the impactor and the stamp is controlled in such a way that the latter initially lags behind the plunger when the plunger is lowered and, after the object to be wrapped has been pressed through the shaping device, is lowered so far relative to the plunger that the plunger and the receptacle touch and thus complement their hollow spaces to form a spherical shape, in which the plunger does not penetrate.

Aufgrund dieser Lösung ist es möglich, einen runden, mit kleinen oberflächlichen Erhöhungen versehenen Gegenstand in eine dünne Alufolie schnell und einfach einzuwickeln, ohne dass irgendwelche Handgriffe erforderlich sind und ohne dass Beschädigungen an Gegenstand und Folie auftreten.Due to this solution, it is possible to quickly and easily wrap a round object provided with small superficial elevations in a thin aluminum foil without any manipulations and without damage to the object and the foil.

In den Fig. 1 bis 4 wird ein runder Gegenstand, der mit kleinen auf der Oberfläche verteilten Erhöhungen versehen ist, und der z.B. eine mit einer gehackte Nüsse enthaltenden Schokoladenpaste überzogene Süssware sein kann, mit S bezeichnet.1 to 4 a round object is provided which is provided with small ridges distributed on the surface and which e.g. can be a confectionery coated with a chocolate paste containing chopped nuts, denoted by S.

Mit A wird eine dünne Alufolie bezeichnet, die dazu bestimmt ist, als Verpackung um den Gegenstand S gewickelt zu werden.A denotes a thin aluminum foil, which is intended to be wrapped around the object S as packaging.

Mit 1 wird eine Aufnahme mit einem halbkugeligen Hohlraum bezeichnet.1 with a recording with a hemispherical cavity is called.

Über der Aufnahme 1 befindet sich eine Formvorrichtung 3, bestehend aus einem koaxial zum halbkugeligen Hohlraum 2 angeordneten Ring 4, von dem mehrere elastische Lamellen 5 ausgehen, deren freie Enden 6 bei der Aufnahme 1 zusammenlaufen.Above the receptacle 1 there is a shaping device 3, consisting of a ring 4 arranged coaxially to the hemispherical cavity 2, from which a plurality of elastic lamellae 5 extend, the free ends 6 of which converge in the receptacle 1.

Ein Stempel 7 mit einem halbkugeligen Hohlraum 8 ist koaxial zum halbkugeligen Hohlraum 2 angeordnet und der Aufnahme 1 zugewendet.A stamp 7 with a hemispherical cavity 8 is arranged coaxially with the hemispherical cavity 2 and faces the receptacle 1.

Der Stempel 7 bewegt sich zur Formvorrichtung 3 zwischen einer angehobenen Lage (Fig. 1, 2), in der die Formvorrichtung 3 zwischen der Aufnahme 1 und dem Stempel 7 gelagert ist und einer abgesenkten Lage (Fig. 4), in der der Stempel 7 die Aufnahme 1 berührt.The stamp 7 moves to the molding device 3 between a raised position (FIGS. 1, 2) in which the molding device 3 is mounted between the receptacle 1 and the stamp 7 and a lowered position (FIG. 4) in which the stamp 7 touches the recording 1.

Durch den Stempel 7 bewegt sich ein Stössel 9, der sich ebenfalls durch die Formvorrichtung 3 bewegt.A plunger 9 moves through the stamp 7 and also moves through the shaping device 3.

Fig. 5 zeigt ein Gestell 10, weiches ein Paar von Aufnahmen 11 trägt, von denen jede einen halbkugeligen, nach oben gerichteten Hohlraum 12 aufweist.Fig. 5 shows a frame 10 which carries a pair of receptacles 11, each of which has a hemispherical, upward cavity 12.

Über den Aufnahmen 11 trägt das Gestell 10 ein Paar von Formvorrichtungen 13 mit jeweils einem koaxial mit dem darunterliegenden Hohlraum 12 angeordneten Ring 14.Above the receptacles 11, the frame 10 carries a pair of shaping devices 13, each with a ring 14 arranged coaxially with the cavity 12 underneath.

Wie in den Fig. 6 und 9 besser zu erkennen ist, gehen vom Ring 14 einer jeden Formvorrichtung 13 erste und zweite elastische Lamellen 15a, 15b aus, die in abwechselnder Folge um den Rand von Ring 14 angeordnet sind.As can be seen better in FIGS. 6 and 9, first and second elastic lamellae 15a, 15b, which are arranged in an alternating sequence around the edge of ring 14, start from ring 14 of each shaping device 13.

Die Lamellen 1 5a, 15b sind derart geformt, dass sie in der Ruhestellung, dargestellt in Fig. 6 bis 9, die freien Enden 16a der ersten Lamellen 15a mit gegenseitiger Berührung in eine axiale Lage zum Ring 14 bringen. In der gleichen Ruhestellung decken die freien Enden 16b der zweiten Lamellen 15b teilweise die Spalte zu, die sich zwischen den ersten Lamellen 15a öffnen.The lamellae 15a, 15b are shaped such that in the rest position, shown in FIGS. 6 to 9, they bring the free ends 16a of the first lamellae 15a into an axial position with respect to the ring 14 with mutual contact. In the same rest position, the free ends 16b of the second fins 15b partially cover the Gaps that open between the first fins 15a.

Wie man im folgenden sehen wird, sollen die Lamellen 15a, 15b sich auseinanderspreizen, um das Passieren des einzuwickelnden Gegenstandes zu ermöglichen. Um eine geordnete Rückkehr der Lamellen 15a,15b in die oben beschriebene Ruhestellung zu erleichtern, sind die Enden 16b der zweiten Lamellen 15b jeweils V-förmig ausgebildet und öffnen sich zur Aussenseite der Formvorrichtung 13. Dagegensind die freien Enden 16b der ersten Lamellen 15a am Ende verjüngt.As will be seen in the following, the lamellae 15a, 15b should spread apart to enable the object to be wrapped to pass through. In order to facilitate an orderly return of the fins 15a, 15b to the rest position described above, the ends 16b of the second fins 15b are each V-shaped and open to the outside of the molding device 13. In contrast, the free ends 16b of the first fins 15a are at the end rejuvenated.

Vorzugsweise laufen die Spitzen der freien Enden 16a, 16b der Lamellen 15a, 1 5b strahlenförmig in Richtung der äusseren Formvorrichtung 13 auseinander.The tips of the free ends 16a, 16b of the fins 15a, 15b preferably diverge in the direction of the outer shaping device 13 in the form of a beam.

Wie Fig. 5 zeigt, befindet sich koaxial zu jeder Formvorrichtung 13 ein senkrecht zum Gestell 10 bewegbarer Stempel 17, der jeweils am der Aufnahme 11 zugewandten Ende einen halbkugeligen Hohlraum 18 bildet.5 shows, coaxially to each molding device 13 there is a plunger 17 which can be moved perpendicular to the frame 10 and which forms a hemispherical cavity 18 at the end facing the receptacle 11.

Der Stempel 17 bewegt sich axial um einen Stössel 19, dessen Vertikalbewegung gegenüber den Formvorrichtungen 13 durch einen Gleitholm 20 bewerkstelligt wird, der entlang von Pfosten 21 des Gestells bewegbar ist.The plunger 17 moves axially around a plunger 19, the vertical movement of which relative to the shaping devices 13 is brought about by a sliding beam 20 which can be moved along posts 21 of the frame.

Jedem Stempel 17 ist ein Linearantrieb 22 zugeordnet, der eine Axialbewegung jedes Stössels 19 gegenüber dem Stempel 17 ermöglicht.A linear drive 22 is assigned to each punch 17, which enables each plunger 19 to move axially relative to the punch 17.

Vorzugsweise weist das äussere Ende des der Aufnahme 11 zugewandten Stössels 19 ebenfalls einen Hohlraum 19a auf. Der Hohlraum 19a hat eine kugelförmige Oberfläche und dient dazu, in der Stellung, in der der Stössel 19 vollständig in den Axialhohlraum des Stempels 17 zurückgezogen ist, den Pol des halbkugeligen Hohlraumes 18 auszufüllen.Preferably, the outer end of the plunger 19 facing the receptacle 11 also has a cavity 19a. The cavity 19a has a spherical surface and, in the position in which the plunger 19 is completely retracted into the axial cavity of the plunger 17, serves to fill the pole of the hemispherical cavity 18.

Zwischen den Formvorrichtungen 13 und den Aufnahmen 11 befindet sich eine Übertragungsvorrichtung 23 aus einer mit Löchern 24 versehenen Platte, von denen jedes koaxial zur darüberliegenden Formvorrichtung 13 ist.Between the molding devices 13 and the receptacles 11 there is a transfer device 23 made of a plate provided with holes 24, each of which is coaxial with the molding device 13 above.

Die Übertragungsvorrichtung 23 gleitet vertikal auf den Pfosten 25 des Gestells 10 unter Einwirkung eines Linearantriebs 26. Das Gestell 10 ist ausserdem mit einem Paar Horizontalführungen 26a versehen, die durch die von den Pfosten 21 und der Gleitschiene 20 gebildete Öffnung laufen.The transmission device 23 slides vertically on the post 25 of the frame 10 under the action of a linear drive 26. The frame 10 is also provided with a pair of horizontal guides 26a which run through the opening formed by the post 21 and the slide rail 20.

Über die Horizontalführungen 26a gleitet eine Führungsplatte 27, die zur Öffnungsoberfläche der Formvorrichtung 13 gesehen einen Hohlraum 28 bildet, der geeignet ist, eine dünne Alufolie (in Fig. 5 nicht dargestellt), welche, in Stücke geteilt, dazu bestimmt ist, einen Gegenstand einzuwickeln, aufzunehmen.A guide plate 27 slides over the horizontal guides 26a and, when viewed towards the opening surface of the molding device 13, forms a cavity 28 which is suitable for a thin aluminum foil (not shown in FIG. 5), which, divided into pieces, is intended for wrapping an object to record.

Die Platte 27 ist mit Löchern 29 versehen, von denen sich jedes koaxial zu einer Formvorrichtung 13 befindet. Bei Gebrauch der Vorrichtung wird in jedes der Löcher 29, eventuell im Zusammenhang mit einer (nicht dargestellten) Füllstation, die neben der erfindungsgemässen Vorrichtung eingerichtet wird, ein runder, einzuwickelnder Gegenstand gegeben.The plate 27 is provided with holes 29, each of which is coaxial with a molding device 13. When using the device, a round object to be wrapped is placed in each of the holes 29, possibly in connection with a filling station (not shown) which is set up next to the device according to the invention.

Mit Vorrücken der Führungsplatte 27 längs den Führungen 26a wird jeder der einzuwickelnden Gegenstände passend zur Öffnungsseite der jeweiligen Formvorrichtung 13 gelegt, wo er von einer passenden Alufolie gehalten wird, wie in Fig. 1 schematisch dargestellt wird.As the guide plate 27 advances along the guides 26a, each of the objects to be wrapped is placed to match the opening side of the respective shaping device 13, where it is held by a suitable aluminum foil, as is shown schematically in FIG. 1.

Sobald die Axialität des einzuwickelnden Gegenstandes zur entsprechenden Formvorrichtung 13 erfüllt ist, wird der Gleitholm 20 so gesteuert, dass sich die Stössel 19 nach unten bewegen. Gleichzeitig wird jeder Linearantrieb 22 so gesteuert, dass der entsprechende Stempel 17 gegenüber dem Stössel 19 zurückgezogen bleibt, der auf diese Weise in bezug auf den halbkugeligen Hohlraum 18 nach unten herausragt.As soon as the axiality of the object to be wrapped to the corresponding shaping device 13 is satisfied, the sliding beam 20 is controlled in such a way that the plungers 19 move downward. At the same time, each linear drive 22 is controlled so that the corresponding plunger 17 remains retracted relative to the plunger 19, which in this way protrudes downward with respect to the hemispherical cavity 18.

Die Abwärtsbewegung der Stössel 19 bewirkt, wie Fig. 2 schematisch zeigt, ein Vorrücken des einzuwickelnden Gegenstandes und der Alufolie zwischen die elastischen Lamellen 1 5a, 1 5b der Formvorrichtung 13. Auf diese Weise legt sich die Alufolie um die vordere Oberfläche des Gegenstandes.The downward movement of the plunger 19, as shown schematically in FIG. 2, causes the object to be wrapped and the aluminum foil to advance between the elastic lamellae 15a, 15b of the shaping device 13. In this way, the aluminum foil lies around the front surface of the object.

Während der Vorrückbewegung spreizen sich die elastischen Lamellen auseinander und bewirken so ein «Kämmen» des Gegenstandes, so dass eine erste Formung der Alufolie entsprechend der hinteren Oberfläche des Gegenstandes erfolgt.During the advancing movement, the elastic lamellas spread apart and thus "comb" the object, so that the aluminum foil is first shaped in accordance with the rear surface of the object.

Durch eine weitere Vertikalbewegung des Stössels 19 wird der teilweise eingewickelte Gegenstand aus der Formvorrichtung 13 herausgestossen. Durch das Wiederschliessen der Lamellen 15a, 15b beim Ausstossen des Gegenstandes wird eine zweite Formgebung der Alufolie auf der Oberfläche des Gegenstandes bewirkt. Auf diese Weise erhält man ein hinteres, schwanzförmiges Anhängsel, bestehend aus dem noch nicht am Gegenstand anliegenden Teil der Alufolie.A further vertical movement of the plunger 19 pushes the partially wrapped object out of the shaping device 13. By re-closing the fins 15a, 15b when the object is ejected, a second shaping of the aluminum foil on the surface of the object is brought about. In this way, a tail-shaped tail is obtained, consisting of the part of the aluminum foil that has not yet touched the object.

Die Anordnung der Lamellen 1 5a, 15b um den Rand des Ringes 14 und die Gestaltung der äusseren Enden 16a, 16b bewirken, dass sich die elastischen Lamellen, deren freie Enden 16a, 16b sich längs des grössten Durchmessers (Fig. 2) des Gegenstandes in der grössten Spreizung aneinanderreihen, ordnungsgemäss beim Ausstossen des Gegenstandes aus der Formvorrichtung 13 wieder schliessen. Die Formgebung des schwanzähnlichen Anhängsels erfolgt deshalb ohne Zerreissen und Deformieren.The arrangement of the fins 1 5a, 15b around the edge of the ring 14 and the design of the outer ends 16a, 16b cause the elastic fins, the free ends 16a, 16b of which extend along the largest diameter (FIG. 2) of the object the largest spread together, close properly when the object is ejected from the molding device 13. The tail-like tag is therefore shaped without tearing and deforming.

Nach Beendigung des Ausstossens, an dem zusätzlich zur Aktion der Antriebsstange 1 9 auch die Rückkraft der elastischen Lamellen 15a, 1 5b mitwirkt, wird der Gegenstand im Hohlraum 12 der Aufnahme 11 aufgenommen.After the ejection has ended, in which, in addition to the action of the drive rod 19, the return force of the elastic lamellae 15a, 15b also participates, the object is received in the cavity 12 of the receptacle 11.

Synchron zur Vorrückbewegung des Gegenstandes zwischen dem unteren Ende der Formvorrichtung 13 und dem Hohlraum 12 senkt sich die Übertragungsvorrichtung 23, die sich normalerweise in angehobener Stellung, wie in Fig. 5 gezeigt, befindet, aufgrund der Betätigung des Linearantriebs 26 und berührt die Aufnahme 11.In synchronism with the advancement of the object between the lower end of the shaping device 13 and the cavity 12, the transmission device 23, which is normally in the raised position, as shown in FIG. 5, lowers due to the actuation of the linear drive 26 and touches the receptacle 11.

Die Übertragungsvorrichtung 23 steuert den Gegenstand während der Vorrückbewegung und stellt somit sicher, dass das Anhängsel der Alufolie, das noch nicht um den Gegenstand gelegt ist, seine Axialstellung zum Hohlraum 12 einhält.The transmission device 23 controls the object during the advancing movement and thus ensures that the appendage of the aluminum foil, which has not yet been placed around the object, maintains its axial position with respect to the cavity 12.

Sobald der Gegenstand aus der Formvorrichtung 13 ausgestossen worden ist, können die Linearantriebe 22 und der Gleitholm 20 derart gesteuert werden, dass sich jeder Stempel 17 längs des jeweiligen Stössels 19 bewegt, um das Ende des Hohlraumes 19b jedes Stössels 19 mit dem Pol des dazugehörigen halbkugeligen Hohlraumes 18 auszurichten und durch die Formvorrichtung 13 hindurch den halbkugeligen Hohlraum selbst in Berührung mit dem entsprechenden Hohlraum 12 der Aufnahme zu bringen.As soon as the article has been ejected from the molding device 13, the linear drives 22 and the sliding beam 20 can be controlled in such a way that each punch 17 moves along the respective plunger 19, around the end of the cavity 19b of each plunger 19 with the pole of the associated one Align hemispherical cavity 18 and bring through the molding device 13 through the hemispherical cavity itself in contact with the corresponding cavity 12 of the receptacle.

Wie in Fig. 4 schematisch dargestellt wird, wird durch diese Aktion das rückwärtige, noch nicht an den Gegenstand angelegte Anhängsel an den Gegenstand angedrückt. So wird der Einwickelvorgang vervollständigt.As is shown schematically in FIG. 4, this action presses the rear appendage, which has not yet been applied to the object, onto the object. This completes the wrapping process.

Nachdem die vom Gleitholm 20 und der Formvorrichtung 13 getragenen Stempel durch die Formvorrichtung 13 wieder nach oben bewegt worden sind, können die in der Aufnahme 11 enthaltenen, eingewickelten Produkte weiteren Verpackungsvorgängen zugeführt werden.After the stamps carried by the slide beam 20 and the shaping device 13 have been moved up again by the shaping device 13, the wrapped products contained in the receptacle 11 can be fed to further packaging processes.

Die Bewegung der erwähnten Stempel durch die Formvorrichtung 13 wird dadurch erleichtert, dass die Spitzen der äusseren Enden 16a, 16b der elastischen Lamellen 15a, 15b strahlenförmig gegen das äussere Ende der Formvorrichtung 13 auseinanderlaufen. Diese Spitzen greifen jedoch nicht in die Bewegung des Kopfteiles der Stempel 17 ein.The movement of the stamps mentioned by the shaping device 13 is facilitated in that the tips of the outer ends 16a, 16b of the elastic lamellae 15a, 15b diverge radially towards the outer end of the shaping device 13. However, these tips do not interfere with the movement of the head part of the stamp 17.
