Abstract

The invention relates to an enveloping machine for cuboid articles, especially cigarette packs (3), with a turret (1) having cells (2), with a slide (4) for pushing the articles (3) over into the cells (2), with a device (6) for feeding foil portions (7) into the region between the slide (4) and cell (2), and with an upper and a lower folder (16, 18). So as to treat the articles (3) carefully and for a reliable transfer of the lower fold into the turret arc, the drive (20) for the lower folder (18) is so designed that it first approaches the cigarette pack (3), at the same time taking up the lower wrap-over portion (12), comes to bear on the cigarette pack, moves along on the lower wrap-over portion (12) until it overlaps this, and lifts off during the further advance of the turret (1), during which the upper wrap-over portion (13) of the foil portion (7) is wrapped round as a result of the turret rotation. <IMAGE>

Description

Die Erfindung betrifft eine Folieneinschlagmaschine für quaderförmige Gegenstände, insbesondere Zigarettenpäckchen, mit einem Zellen aufweisenden und schrittweise drehbaren Revolver, einem Schieber zum Überschieben der Ge­genstände in jeweils eine Zelle, einer Zuführeinrichtung für Folienabschnitte in den Bereich zwischen Schieber und Zelle sowie mit einem Ober- und einem Unterfalter, wobei der Oberfalter durch einen in Drehrichtung des Revolvers be­nachbart der Position der in Aufnahmeposition befindlichen Zelle beginnenden Revolverbogen gebildet wird und der Unterfalter von unten in Anlage an die nach außen gerichtete Seite des in der in Aufnahmeposition befindlichen Zelle aufgenommenen Gegenstandes mittels eines Antriebs beweglich ist.The invention relates to a film wrapping machine for cuboid objects, in particular cigarette packs, with a revolver which has cells and can be rotated step by step, a slide for pushing the objects into a cell, a feed device for film sections into the area between the slide and cell, and with an upper and a Unterfalter, wherein the Oberfalter is formed by a revolver arc beginning in the direction of rotation of the revolver adjacent to the position of the cell in the receiving position and the lower folder is movable from below into contact with the outward-facing side of the object received in the receiving position cell by means of a drive .

Bei derartigen bekannten Folieneinschlagmaschinen ist es bekannt, den Unterfalter für den unteren Überschlag des zum Einschlagen verwendeten Folien­abschnitts am Ende eines Hebels anzuordnen, der um das andere Ende derart am Revolver schwenkbar gelagert ist, daß der Unterfalter den unteren Überschlag umlegt und gegen das Zigarettenpäckchen schlägt, wonach der Revolver weiter­dreht. Bei einem derartigen Bewegungsablauf, der zudem mit hohen Taktzeiten abläuft, besteht die Gefahr, daß das Zigarettenpäckchen an der entsprechenden Kante, um die der untere Unterschlag umgelegt wird, beschädigt und die Unter­faltung wieder zurückgezogen wird.In known film wrapping machines of this type, it is known to arrange the lower folder for the lower flap of the film section used for wrapping in at the end of a lever which is pivotably mounted on the revolver around the other end in such a way that the lower folder flips over the lower flap and hits the packet of cigarettes, after which the revolver continues to turn. With such a sequence of movements, which also runs at high cycle times, there is a risk that the packet of cigarettes will be damaged at the corresponding edge around which the lower flap is folded and the folding will be withdrawn again.

Außerdem ist es aus der DD-A-119 995 bekannt, bei einer Folienein­schlagmaschine den Oberfalter unterhalb der Revolverzelle, in die ein einzu­hüllendes Zigarettenpäckchen eingeschoben wird, anzuordnen, während der Un­terfalter entsprechend oberhalb angeordnet ist und zwei Bewegungen ausführt, eine senkrecht entlang des Päckchen zum Umlegen des unteren Überschlags des Folienabschnitts, die von einer Kurve gesteuert wird, wonach sich der Revolver weiterdreht, und einer zweiten Schwenkbewegung, um aus dem Einschubbereich für das nächste Zigarettenpäckchen herauszugelangen. Dadurch, daß der Unterfalter in Anlage am Zigarettenpäckchen bleibt, während der Revolver weiterschaltet, übt der Unterfalter aufgrund der Reibung eine den unteren Überschlag zurück­ziehende Wirkung aus, zumal bei der Revolverdrehung die nachlaufende Päck­chenkante gegen den Unterfalter drückt. Dies führt zu keiner schonenden Be­handlung der Päckchen und zu nicht genügend stramm sitzenden Klarsichtfolien­umhüllungen.In addition, it is known from DD-A-119 995 to arrange the upper folder below the turret cell, into which a packet of cigarettes to be wrapped is inserted, in a film wrapping machine, while the lower folder is arranged above and executes two movements, one vertically along the packet for turning over the lower flap of the film section, which is controlled by a curve, after which the revolver continues to rotate, and a second pivoting movement in order to get out of the insertion area for the next packet of cigarettes. Due to the fact that the lower folder remains in contact with the cigarette packet while the revolver is advancing, the lower folder exerts a lowering effect on the lower rollover due to the friction, especially since the trailing edge of the packet presses against the lower folder when the turret is rotated. This does not result in gentle handling of the parcels and in insufficiently tight-fitting transparent film wrappings.

Aufgabe der Erfindung ist es daher, eine Folieneinschlagmaschine der eingangs genannten Art zu schaffen, die eine schonende Behandlung der Kanten der Zigarettenpäckchen bei einfacher Konstruktion gewährleistet.The object of the invention is therefore to provide a film wrapping machine of the type mentioned at the outset, which ensures gentle handling of the edges of the packets of cigarettes with a simple construction.

Diese Aufgabe wird dadurch gelöst, daß der Antrieb für den Unterfalter derart ausgebildet ist, daß der Unterfalter einen geschlossenen Umlaufweg durchläuft, auf dem sich der Unterfalter der in Aufnahmeposition befindlichen Zelle aus einer Position mit Abstand zur Zelle und außerhalb deren Einschub­bereich bis zur Anlage an dem in die Zelle eingeschobenen Gegenstand den un­teren Überschlag des Folienabschnitts überlappend nähert, sich entlang des Bereichs des unteren Überschlags bis zur im wesentlichen vollständigen Über­deckung hiervon in Anlage verbleibend bewegt, sich zu Beginn des Weiterschal­tens des Revolvers in Richtung der Zellendrehung weiterbewegt und dann ablüf­tet und in die Ausgangsstellung zurückkehrt.This object is achieved in that the drive for the sub-folder is designed such that the sub-folder passes through a closed circulation path on which the sub-folder of the cell in the receiving position is from a position at a distance from the cell and outside its insertion area to the system on the Object inserted into the cell overlaps the lower flap of the film section, moves along the region of the lower flap until it is essentially completely covered, moves further in the direction of the cell rotation at the beginning of the indexing of the revolver and then vented and into the Starting position returns.

Hierdurch wird erreicht, daß sich der Unterfalter dem in der Zelle des Revolvers befindlichen Zigarettenpäckchen den unteren Überschlag mitnehmend bis zur Anlage nähert, sich entlang der entsprechenden Seite des Zigaretten­päckchens unter Andrücken des unteren Überschlags bewegt und ablüftet, während der obere Überschlag in Richtung auf den unteren Überschlag umgelegt wird. Gleichzeitig erfolgt eine sichere Übergabe der Unterfaltung in den Revolver­bogen.This ensures that the underfold takes the lower rollover to the cigarette packet in the cell of the revolver and moves towards the system, moves along the corresponding side of the cigarette packet while pressing on the lower rollover, and ventilates, while the upper rollover in the direction of the lower one Rollover. At the same time, the underfold is securely transferred to the revolver bow.

Weitere Ausgestaltungen der Erfindung sind der nachfolgenden Beschrei­bung und den Unteransprüchen zu entnehmen.Further embodiments of the invention can be found in the following description and the subclaims.

Als Antrieb eignet sich insbesondere eine kurvengesteuerter Parallelo­grammantrieb, jedoch kann auch ein Antrieb aus einer in einer Führung geführ­ten Führungsstange, wobei die Führung ihrerseits zusätzlich verschwenkbar ist, verwendet werden.A curve-controlled parallelogram drive is particularly suitable as the drive, but a drive from a guide rod guided in a guide can also be used, the guide itself being additionally pivotable.

Die Erfindung wird nachstehend anhand eines in den beigefügten Abbil­ dungen dargestellten Ausführungsbeispiels näher erläutert.

  • Fig. 1 zeigt schematisiert und ausschnittweise in Frontansicht eine Fo­lieneinschlagmaschine.
  • Fig. 2 zeigt eine Seitenansicht von Fig. 1 mit dem Antrieb für den Un­terfalter.
  • Fig. 3a bis 3d zeigen den Bewegungsablauf für den Unterfalter der Fo­lieneinschlagmaschine.
The invention is described below with the aid of an illustration in the appended tion illustrated embodiment explained in more detail.
  • Fig. 1 shows schematically and partially a front view of a film wrapping machine.
  • Fig. 2 shows a side view of Fig. 1 with the drive for the lower folder.
  • 3a to 3d show the sequence of movements for the lower folder of the film wrapping machine.

Die dargestellte Folieneinschlagmaschine umfaßt einen Revolver 1, der Zellen 2 zur Aufnahme von Zigarettenpäckchen 3 aufweist und durch einen nicht dargestellten Schrittschaltantrieb um jeweils eine Zellenteilung schrittweise in Richtung des Pfeils drehbar ist. Ferner ist ein Schieber 4 vorgesehen, mittels dem ein in Einschubposition gebrachtes Zigarettenpäckchen 3 entlang eines Überführungsweges 5 in die in Aufnahmeposition befindliche Zelle 2 des Revolvers 1 schiebbar ist.The film wrapping machine shown comprises a revolver 1 which has cells 2 for receiving cigarette packs 3 and can be rotated step by step in the direction of the arrow by a cell division in each case by means of a stepping drive drive (not shown). Furthermore, a slide 4 is provided, by means of which a cigarette packet 3 brought into the insertion position can be pushed along a transfer path 5 into the cell 2 of the revolver 1 which is in the receiving position.

Außerdem ist eine Zuführeinrichtung 6 für Folienabschnitte 7, die üb­licherweise mit einem Aufreißstreifen versehen sind, vorgesehen. Die Zuführ­einrichtung 6 umfaßt ein rotierendes und ein feststehendes Messer 8, 9 sowie ein Zuführrollenpaar 10, das den durch die Messer 8, 9 von einem Folienband 11 abgetrennten Folienabschnitt 7 zum Einhüllen eines Zigarettenpäckchens 3 in den Überführungsweg 5 des Zigarettenpäckchens 3 befördert, das den Folienab­schnitt 7 beim Überschieben in die Zelle 2 durch den Schieber 4 mitnimmt. Hierdurch gelangt der Folienabschnitt 7 zunächst in Anlage an die vorlaufende Seite des Zigarettenpäckchens 3 und dann in Anlage an die Ober- und Untersei­te, so daß bei dem in der Zelle 3 befindlichen Zigarettenpäckchen 3 der untere und obere Überschlag 12, 13 nach außen gegenüber der Zelle 2 überstehen. (Desgleichen steht der Folienabschnitt 7 seitlich über, vgl. Fig. 2, wobei die stirnseitigen Zipfel 14 durch entsprechende Seitenfalter 15 beim Überschieben bereits eingefaltet wurden.)In addition, a feed device 6 for film sections 7, which are usually provided with a tear strip, is provided. The feed device 6 comprises a rotating and a fixed knife 8, 9 and a pair of feed rollers 10 which conveys the film section 7, separated by the knives 8, 9 from a film band 11, for wrapping a cigarette packet 3 into the transfer path 5 of the cigarette packet 3, which transports the film section 7 entrains when pushed into cell 2 by slide 4. As a result, the film section 7 first comes into contact with the leading side of the cigarette packet 3 and then into contact with the upper and lower sides, so that in the case of the cigarette packet 3 located in the cell 3, the lower and upper rollover 12, 13 to the outside opposite the cell 2 survive. (Likewise, the film section 7 protrudes laterally, cf. FIG. 2, the end tips 14 having already been folded in by corresponding side folders 15 when pushed over.)

Benachbart zum Revolver 1 befindet sich ein feststehender Revolverbogen 16, der in Höhe der in Drehrichtung vorlaufenden Innenseite des Aufnahmeraums der in Aufnahmeposition befindlichen Zelle 3 beginnt und an der dem Revolver 1 zugekehrten Seite eine Abschrägung 17 aufweist.Adjacent to the revolver 1 there is a fixed revolver bend 16 which begins at the level of the inner side of the receiving space of the cell 3 in the receiving position and which has a bevel 17 on the side facing the revolver 1.

Ferner ist ein Unterfalter 18 vorgesehen, der über ein Tragelement 19 mit einem Parallelogrammantrieb 20 verbunden ist.A folder 18 is also provided, which is connected to a parallelogram drive 20 via a support element 19.

Der Parallelogrammantrieb 20 umfaßt zwei mit Abstand zueinander in einer Gehäusewandung 21 befestigte Lagerhülsen 22, 23, die zur Lagerung jeweils ei­ner von zwei parallelen Achsen 24, 25 dienen. Auf der Achse 24 befindet sich eine Kurbel 26. Die Kurbel 26 nimmt eine Achse 27 auf, auf der ferner eine Stange 28 mit einem Ende gelagert ist, während das andere Ende auf einer Achse 29 einer Kurbel 30 drehbar angeordnet ist. Die Kurbel 30 ist bezüglich der Achse 25 drehbar angeordnet. Die Achse 25 ist mit einem Hebel 31 verbunden, der an seinem freien Ende zwei Rollen 32 zum Eingriff mit zwei Steuerkurven 33 trägt. Über letztere wird der Bewegungsablauf des Unterfalters 18 gesteuert. Die Stange 28 kann wie beim dargestellten Ausführungsbeispiel gegen eine Feder 34 teleskopartig zusammendrückbar ausgebildet sein.The parallelogram drive 20 comprises two bearing sleeves 22, 23 fastened at a distance from one another in a housing wall 21, each of which serves for mounting one of two parallel axes 24, 25. Located on axis 24 a crank 26. The crank 26 receives an axle 27, on which a rod 28 is also supported at one end, while the other end is rotatably arranged on an axle 29 of a crank 30. The crank 30 is rotatably arranged with respect to the axis 25. The axis 25 is connected to a lever 31 which carries at its free end two rollers 32 for engagement with two control cams 33. The movement sequence of the lower folder 18 is controlled via the latter. As in the exemplary embodiment shown, the rod 28 can be designed to be telescopically compressible against a spring 34.

Fig. 3a zeigt die Ausgangsposition des Unterfalters 18, nachdem ein Zi­garettenpäckchen 3 mit einem Folienabschnitt 7 in die in Aufnahmeposition be­findliche Zelle 3 des Revolvers 1 eingeschoben wurde. Aus dieser Position mit Abstand vor der Zelle 3 und außerhalb des Überführungsweges 5 nähert sich der Unterfalter 18 zunächst dem unteren Überschlag 12, um sich dann in einer Be­wegung schräg auf die geringfügig aus der Zelle 3 herausragende Seite des Zi­garettenpäckchens 3 hin unter Mitnahme des unteren Überschlags 12 dem Ziga­rettenpäckchen 3 zu nähern und in Anlage hieran unter teilweiser Überlappung mit dem unteren Überschlag 12 zu gelangen.3a shows the starting position of the lower folder 18 after a cigarette packet 3 with a film section 7 has been inserted into the cell 3 of the revolver 1 in the receiving position. From this position at a distance in front of the cell 3 and outside the transfer path 5, the lower folder 18 first approaches the lower flap 12, in order then to move obliquely towards the side of the cigarette packet 3 which slightly protrudes from the cell 3, taking the lower flap with it 12 to approach the packet of cigarettes 3 and to come into contact with it with partial overlap with the lower rollover 12.

Dann bewegt sich der Unterfalter 18 an dem Zigarettenpäckchen 3 entlang, bis er den daran zur Anlage gebrachten unteren Überschlag 12 im wesentlichen vollständig überdeckt, Fig. 3b. Hierbei wird durch den Unterfalter 18 eine ziehende Wirkung infolge Reibung auf den unteren Überschlag 12 in Richtung von der Umlegekante des unteren Überschlag 12 weg zum straffen Anlegen des unteren Überschlags 12 ausgeübt.Then the underfold 18 moves along the cigarette packet 3 until it substantially completely covers the lower rollover 12 which has been brought into contact with it, FIG. 3b. In this case, the lower folder 18 exerts a pulling action due to friction on the lower rollover 12 in the direction away from the fold-over edge of the lower rollover 12 in order to tighten the lower rollover 12.

Nun beginnt sich der Revolver 1 zu drehen und der Unterfalter 18 bewegt sich noch ein kurzes Stück in Richtung des Zellenweges an dem Zigarettenpäck­chen 3 anliegend mit. Der obere Überschlag 13, der sich benachbart zur Kante des Revolverbogens 16 befindet, wird zunächst durch die Abschrägung 17 bei der Bewegung des Revolvers 1 schräg in Richtung auf den bereits umgelegten unteren Überschlag 12 umgelegt. Hierbei gleitet der obere Überschlag 13 an der Ab­schrägung 17 entlang und bildet zunächst einen Winkel zum Zigarettenpäckchen 3 derart, daß der Unterfalter 18 entweichen kann, der zu Beginn des Umlegens des oberen Überschlags 13 durch den sich an die Abschrägung 17 anschließenden Ab­schnitt des Oberfalters 16 oder etwas vorher ablüftet und damit die Kante, um die der untere Überschlag 12 umgelegt wurde, freigibt, so daß diese nicht be­ansprucht wird, Fig. 3c. Außerdem wird keine zurückziehende Wirkung durch den Unterfalter 18 auf den umgelegten unteren Überschlag 12 ausgeübt.Now the revolver 1 begins to rotate and the subfold 18 moves a short distance in the direction of the cell path with the cigarette packet 3. The upper flap 13, which is located adjacent to the edge of the revolver arch 16, is first folded obliquely in the direction of the lower flap 12 already flipped by the bevel 17 during the movement of the revolver 1. Here, the upper flap 13 slides along the bevel 17 and initially forms an angle to the packet of cigarettes 3 such that the lower folder 18 can escape, which at the beginning of the folding of the upper flap 13 through the section of the upper folder 16 or vented somewhat beforehand and thus releases the edge around which the lower rollover 12 has been folded over, so that it is not claimed, FIG. 3c. In addition, the retractor 18 has no retracting effect on the folded-over lower flap 12.

Bei Weiterdrehung des Revolvers 1 legt der durch den Revolverbogen 16 gebildete Oberfalter den oberen Überschlag 13 vollständig auf den unteren Überschlag 12 um, Fig. 3d.When the revolver 1 continues to rotate, the revolver bends 16 formed Oberfalter the upper flap 13 completely on the lower flap 12, Fig. 3d.

Der Unterfalter 18 kehrt in seine Ausgangsposition gemäß Fig. 3a zurück, währenddessen wird das nächste Zigarettenpäckchen 3 in eine neue, in Aufnahm­eposition befindliche Zelle 3 zusammen mit einem Folienabschnitt 7 eingescho­ben.The lower folder 18 returns to its starting position according to FIG. 3a, during which the next packet of cigarettes 3 is inserted into a new cell 3 in the receiving position together with a film section 7.
