Description

Die Erfindung betrifft einen Seitenfaltungspakker für Zigarettenweichpackungen mit einer Verpackungsstation, die eine Zuführeinrichtung für Innenpapierabschnitte quer zur Förderrichtung von zu verpackenden Zigarettenblöcken und Falteinrichtungen zum Falten der Innenpapierabschnitte besitzt, die seitliche Faltdaumen, ein in Förderrichtung hin- und herbewegliches Mundstück zur Aufnahme eines Zigarettenblocks und ein Faltelement aufweisen, das von einer Position oberhalb des Mundstücks in eine dieses übergreifende Faltposition beweglich ist.The invention relates to a side-folding packer for soft cigarette packs with a packaging station which has a feed device for inner paper sections transverse to the conveying direction of cigarette blocks to be packaged and folding devices for folding the inner paper sections, the lateral folding thumbs, a mouthpiece which can be moved back and forth in the conveying direction, and a folding element have, which is movable from a position above the mouthpiece into a folding position spanning this.

Ein derartiger Seitenfaltungspacker ist aus der DE-B-1 173 832 bekannt, bei dem Zigarettenblöcke in ein als Hohlstössel ausgebildetes Mundstück eingeschoben werden, das sich dann mit dem Zigarettenblock bis in eine Stellung weiterbewegt, in der ein Ausräumhebel in Anlage an die Rückseite der Zigaretten gelangt, um beim Rückhub des Mundstücks die Zigaretten zurückzuhalten. Ein als Schlagfalter ausgebildetes Faltelement ist zusammen mit daran vorgesehenen Faltdaumen zum Bilden der inneren Seitenwandbereiche des Innenpapierabschnitts in eine das Mundstück in dessen Ausgangslage übergreifende Faltposition auf einem Kreisbogen schwenkbar, wobei dann durch den Vorwärtshub des Mundstücks die seitlich vorne überstehenden Zipfel auf die inneren Seitenwandbereiche umgelegt werden. Infolgedessen, dass die Bildung der Bodenkanten des Innenpapiers nicht im Stillstand erfolgt, ergibt sich bei hoher Verpackungsgeschwindigkeit keine exakte winklige Anordnung der Lappen des Innenpapiers.Such a side-folding packer is known from DE-B-1 173 832, in which cigarette blocks are inserted into a mouthpiece designed as a hollow plunger, which then moves further with the cigarette block into a position in which a removal lever abuts the rear of the cigarettes reached to hold back the cigarettes during the return stroke of the mouthpiece. A folding element designed as a folding folder can be pivoted together with the folding thumbs provided on it to form the inner side wall regions of the inner paper section into a folding position which overlaps the mouthpiece in its initial position, the projections laterally projecting laterally being then folded over onto the inner side wall regions by the forward stroke of the mouthpiece . As a result of the fact that the bottom edges of the inner paper are not formed at a standstill, there is no exact angular arrangement of the flaps of the inner paper at high packaging speeds.

Aufgabe der Erfindung ist es, einen Seitenfaltungspacker der eingangs genannten Art zu schaffen, der eine hohe Verpackungsgeschwindigkeit gewährleistet, wobei jedoch die Bildung der Bodenkanten praktisch wie im Stillstand erfolgt, so dass sich eine exakt winklige Anordnung der Lappen ergibt, obwohl der zu verpackende Zigarettenblock kontinuierlich gefördert wird, und der konstruktionsmässig einfach ist.The object of the invention is to provide a gusset packer of the type mentioned, which ensures a high packaging speed, but the formation of the bottom edges takes place practically as at a standstill, so that there is an exactly angular arrangement of the rags, even though the cigarette block to be packaged continuously is promoted, and is structurally simple.

Diese Aufgabe wird dadurch gelöst,This task is solved by

dass ein kontinuierlich angetriebener Förderer zum Transportieren der zu verpackenden Zigarettenblöcke durch die Verpackungsstation vorgesehen ist,that a continuously driven conveyor is provided for transporting the packets of cigarettes to be packed through the packaging station,

dass das Faltelement U-förmig, in der Ausgangsposition in Förderrichtung vor der Ausgangsposition des Mundstücks angeordnet, schräg zur Förderrichtung verfahrbar und in der übergreifenden Faltposition solange haltbar ist, bis die inneren Seitenwandbereiche des Innenpapierabschnitts hindurchgelaufen und umgefaltet sind,that the folding element is U-shaped, arranged in the starting position in the conveying direction before the starting position of the mouthpiece, can be moved obliquely to the conveying direction and can be held in the overlapping folding position until the inner side wall regions of the inner paper section have passed through and been folded over,

dass in der Faltposition des Faltelements der Zigarettenblock mit dem Innenpapierabschnitt durch das Faltelement mittels des Förderers förderbar ist,that in the folded position of the folding element the cigarette block with the inner paper section can be conveyed through the folding element by means of the conveyor,

dass die Faltdaumen in Förderrichtung vor der übergreifenden Faltposition des Faltelements stationär angeordnet sind undthat the folding thumbs are arranged stationary in the conveying direction before the overlapping folding position of the folding element and

dass die Geschwindigkeit des U-förmigen Faltelements in Förderrichtung und des Mundstücks mit der Fördergeschwindigkeit synchronisierbar ist.that the speed of the U-shaped folding element in the conveying direction and the mouthpiece can be synchronized with the conveying speed.

Bei einem derartigen Seitenfaltungspacker werden nach der Bildung des Bodenbereichs zunächst die inneren Seitenwandbereiche gefaltet, wonach die sich am Bodenbereich befindlichen seitlichen Zipfel umgefaltet werden, worauf die äusseren Seitenwandbereiche auf die inneren Seitenwandbereiche gefaltet werden, so dass die Zipfel zwischen den äusseren und inneren Seitenwandbereichen zu liegen kommen und daher beim Zurückschieben von nicht benötigten Zigaretten in die Packung nicht stören.In such a side-folding packer, after the bottom area has been formed, the inner side wall areas are first folded, after which the side corners located on the bottom area are folded over, whereupon the outer side wall areas are folded onto the inner side wall areas so that the corners lie between the outer and inner side wall areas come and therefore do not interfere when pushing unnecessary cigarettes back into the pack.

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.

Gemäss den Fig. 1 und 2 besitzt der Seitenfaltungspacker eine nicht dargestellte Förderkette für Zigarettenblöcke 10, die mittels Kettenhaken 11 (Fig. 3) mit konstanter Vorschubgeschwindigkeit gefördert und in ein Mundstück 12 eingeführt werden. Das Mundstück 12 besitzt unterseitig einen entsprechenden (nicht dargestellten) Schlitz zum Durchtritt des Kettenhakens 11.1 and 2, the side-folding packer has a conveyor chain, not shown, for cigarette blocks 10, which is conveyed by means of chain hooks 11 (FIG. 3) at a constant feed rate and inserted into a mouthpiece 12. The mouthpiece 12 has a corresponding slot (not shown) on the underside for the passage of the chain hook 11.

In Förderrichtung vor dem Mundstück 12 ist eine Zuführeinrichtung 13 für Innenpapierabschnitte 14 vorgesehen. Die Zuführeinrichtung 13 führt Innenpapier von einer Bobine über Vorschubrollen 15 einer Trenneinrichtung 16 zu, durch die die Innenpapierabschnitte 14 abgelängt werden. Der Trenneinrichtung 16 ist ein stationäres Führungsteil 17 nachgeschaltet, das mit zwei L-förmigen seitlichen Führungselementen 18 zusammenarbeitet, so dass der Innenpapierabschnitt 14 entlang dem stationären plattenförmigen Führungsteil 17 seitlich durch die L-förmigen Führungselemente 18 geführt quer zur Förderrichtung der Zigarettenblöcke 10 vor das Mundstück 12 gefördert werden kann.A feed device 13 for inner paper sections 14 is provided in the conveying direction in front of the mouthpiece 12. The feed device 13 feeds inner paper from a bobbin via feed rollers 15 to a separating device 16, through which the inner paper sections 14 are cut to length. The separating device 16 is followed by a stationary guide part 17, which cooperates with two L-shaped lateral guide elements 18, so that the inner paper section 14 is guided along the stationary plate-shaped guide part 17 laterally through the L-shaped guide elements 18 in front of the mouthpiece transversely to the conveying direction of the cigarette blocks 10 12 can be funded.

Das Mundstück 12 ist bezüglich des fördernden Trums der Förderkette hin- und herbeweglich, wobei das Mundstück 12 in der in Fig. 3 dargestellten Stellung eine Geschwindigkeit erreicht hat, die gleich der Förderkettengeschwindigkeit ist. Diese Geschwindigkeit wird bis zur Endposition gemäss Fig. 5 beibehalten, worauf das Mundstück 12 wieder in die Ausgangsposition von Fig. 1 zurückgeführt wird.The mouthpiece 12 can be moved back and forth with respect to the conveying run of the conveyor chain, the mouthpiece 12 in the position shown in FIG. 3 having reached a speed which is equal to the conveyor chain speed. This speed is maintained up to the end position according to FIG. 5, whereupon the mouthpiece 12 is returned to the starting position of FIG. 1.

Bei der Bewegung des Mundstücks 12 in Förderrichtung 19 stösst dieses gegen den Innenpapierabschnitt 14 und führt diesen mit sich. Durch das Entlanglaufen des Mundstücks 12 mit dem Innenpapierabschnitt 14 an einer Auflageplatte 20 und damit durch das Auflaufen des Innenpapierabschnitts 14 auf die in Förderrichtung 19 hintere Kante der Auflageplatte 20 wird der Innenpapierabschnitt 14 auf die Bodenseite des Mundstücks 12 umgelegt. Das Umlegen auf die Oberseite erfolgt durch Freigabe des Innenpapierabschnitts 14 durch die L-förmigen Führungselemente 18, die zu diesem Zweck seitlich von dem stationären Führungsteil 17 über Schwenkeinrichtungen 21 in Richtung der Pfeile 22 wegschwenkbar sind, sowie dadurch, dass der Innenpapierabschnitt 14 durch Stäbe 23 auf das Mundstück 12 aufgelegt wird. Die Stäbe 23 sind über eine Schwenkeinrichtung 24 schwenkbar sowie beidseitig des Mundstücks 12 angeordnet, so dass sie den Innenpapierabschnitt 14 neben dem Mundstück 12 seitlich etwas abwärts drücken, wie in Fig. 3 dargestellt ist.When the mouthpiece 12 moves in the conveying direction 19, it abuts against the inner paper section 14 and carries it with it. By running the mouthpiece 12 with the inner paper section 14 on a support plate 20 and thus by running the inner paper section 14 onto the rear edge of the support plate 20 in the conveying direction 19, the inner paper section 14 is folded over onto the bottom side of the mouthpiece 12. The folding over onto the upper side takes place by releasing the inner paper section 14 by means of the L-shaped guide elements 18, which for this purpose can be swiveled laterally away from the stationary guide part 17 via swiveling devices 21 in the direction of the arrows 22, and by the inner paper section 14 being provided by rods 23 is placed on the mouthpiece 12. The rods 23 can be pivoted via a swiveling device 24 and are arranged on both sides of the mouthpiece 12, so that they push the inner paper section 14 next to the mouthpiece 12 to the side somewhat downwards, as shown in FIG. 3.

Die Stäbe 23 verhindern, dass sich der Innenpapierabschnitt 14 am hinteren freien Ende hochstellen und dadurch den nachfolgenden Faltvorgang stören kann. Die Auflageplatte 20 ist wie das Mundstück 12 zum Hindurchführen der Kettenhaken 11 geschlitzt ausgebildet.The bars 23 prevent the inner paper section 14 from rising up at the rear free end and thereby interfering with the subsequent folding process. The support plate 20, like the mouthpiece 12, is slotted for the passage of the chain hooks 11.

Der Seitenfaltungspacker besitzt ferner ein U-förmiges Faltelement 25, das an einem Schieber 26 befestigt ist, der in einer nicht dargestellten Führung schräg zur Förderrichtung 19 verschiebbar angeordnet ist. In der Ausgangsposition des Faltelements 25 befindet sich dieses in Förderrichtung 19 vor dem Mundstück 12 und oberhalb von diesem, vgl. Fig. 1. Wenn das Mundstück 12 die Position von Fig. 3 erreicht, bewegt sich das Faltelement 25 schräg abwärts in Förderrichtung und umgreift hierbei fortschreitend das vordere Ende des Mundstücks 12 mit dem auf dessen Oberseite zurückgelegten Innenpapierabschnitt von oben. Hierbei ist die Geschwindigkeitskomponente des Faltements 25 in Förderrichtung gleich der Fördergeschwindigkeit und damit gleich der Geschwindigkeit des Mundstücks 12. Die Bewegung des Faltelements 25 erfolgt soweit, bis es eine das Mundstück 12 praktisch übergreifende Faltpostion am in Förderrichtung vorlaufenden Ende des Mundstücks 12 erreicht hat. Daraufhin bleibt das Faltelement 25 solange in dieser Faltposition, bis der Zigarettenblock 10 mit dem Innenpapierabschnitt 14 durchgelaufen ist, wodurch die inneren Seitenwandbereiche 27 gefaltet worden sind. Das Mundstück 12 wird währenddessen in seine Ausgangsposition von Fig. 1 zurückgeführt. Nach Beendigung des Faltens der inneren Seitenwandbereiche 27 (vgl. Fig. 6) wird auch das Faltelement 25 in seine Ausgangsposition gemäss Fig. 1 zurückgeführt.The side-folding packer also has a U-shaped folding element 25 which is fastened to a slide 26 which is arranged so as to be displaceable at an angle to the conveying direction 19 in a guide (not shown). In the starting position of the folding element 25, it is located in the conveying direction 19 in front of the mouthpiece 12 and above it, cf. Fig. 1. When the mouthpiece 12 reaches the position of Fig. 3, the folding element 25 moves obliquely downward in the conveying direction and thereby progressively engages around the front end of the mouthpiece 12 with the inner paper section covered on its top from above. Here, the speed component of the folding element 25 in the conveying direction is equal to the conveying speed and thus to the speed of the mouthpiece 12. The movement of the folding element 25 takes place until it has reached a folding position practically overlapping the mouthpiece 12 at the end of the mouthpiece 12 leading in the conveying direction. The folding element 25 then remains in this folding position until the cigarette block 10 with the inner paper section 14 has passed through, as a result of which the inner side wall regions 27 have been folded. The mouthpiece 12 is in the meantime returned to its starting position in FIG. 1. After the folding of the inner side wall regions 27 (cf. FIG. 6), the folding element 25 is also returned to its starting position according to FIG. 1.

Die Bewegungen des Mundstücks 12, des Faltelements 25, der Führungselemente 18 und der Stäbe 23 erfolgt zweckmässig über entsprechend gestaltete Kurvengetriebe, die mit einem gemeinsamen Antrieb für den Seitenfaltungspacker gekoppelt sind.The movements of the mouthpiece 12, the folding element 25, the guide elements 18 and the rods 23 are expediently carried out via appropriately designed cam mechanisms which are coupled to a common drive for the side-folding packer.

Die seitlich nach Faltung der Seitenwandbereiche 27 überstehenden Zipfel 28 werden dann durch jeweils einen auf jeder Seite seitlich angeordneten Faltdaumen 29, gegen die die Zipfel 28 laufen, einwärts in Richtung auf den Zigarettenblock 10 gefaltet. Das Falten der äusseren Seitenwandbereiche 30 erfolgt dann in üblicher Weise durch entsprechende Faltorgane.The tips 28 protruding laterally after folding the side wall regions 27 are then folded inwards in the direction of the cigarette block 10 by a folding thumb 29, which is arranged on each side and against which the tips 28 run. The outer side wall regions 30 are then folded in the usual way by means of corresponding folding members.

Wie aus Fig. 6 ersichtlich, erfolgt zunächst ein Umlegen des Innenpapierabschnitts 14 in Richtung der Pfeile 31, danach der inneren Seitenwandbereiche 27 in Richtung 32, der Zipfel 28 in Richtung 33 und der äusseren Seitenwandbereiche 30 in Richtung 34.As can be seen from FIG. 6, the inner paper section 14 is first folded in the direction of the arrows 31, then the inner side wall regions 27 in the direction 32, the tips 28 in the direction 33 and the outer side wall regions 30 in the direction 34.
