The turntable 1 has two, preferably one above the other arranged, provided with expandable jaws 2 for a bobbin 3 'or 3' ', which are provided with a bobbin core 4 is in which the receiving pin 2 engages and clamps it. The expiring Bobine 3 '' is according to the illustrated embodiment over the new bobbin 3 '. The bobbins 3 ', 3' 'can for example for the production of the inner paper, the outer paper or the wrapping film serve from cigarette packs.

Um die neue Bobine 3' anspleißen zu können, ist die neue Bobine 3' zunächst zu öffnen. Hierzu sind verschiedene Möglichkeiten bekannt. Im dargestellten Ausführungsbeispiel ist ein Hebel 5 um eine Achse 6 drehbar vorgesehen, der an seinem freien Ende einen Schlitten 7 trägt. Der Schlitten 7 ist über den Hebel 5 gegen den Außenumfang der Bobine 3' schwenkbar und trägt ein schematisch dargestelltes Messer 8, das mit dem Schlitten 7 quer zur Verpackungsmaterialbahn 9' der Bobine 3' beweglich ist, um diese durchzutrennen. Außerdem ist ein radial verschiebarer Friktionskörper mit dem Außenumfang der Bobine 3' in Eingriff bringbar, der bewirkt, daß die Verpackungsmaterialbahn 9' abhebt. Dies kann durch Blasluft, die auf die Schnittstelle gerichtet wird, unterstützt werden. Die Blasluft kann mit zunehmender Stärke oder getaktet aufgebracht werden.In order to be able to splice on the new bobbin 3 ', the new bobbin is 3 'to open first. Various options are known for this. In the illustrated embodiment, a lever 5 is about an axis 6 rotatably provided, a carriage 7 at its free end wearing. The carriage 7 is against the outer circumference of the lever 5 Bobine 3 'pivotable and carries a schematically illustrated knife 8, that with the carriage 7 transverse to the packaging material web 9 'of the bobbin 3 'is movable to cut them. It is also a radially displaceable one Friction body engages with the outer circumference of the bobbin 3 ' bringable, which causes the packaging material web 9 'lifts off. This can be assisted by blowing air directed at the interface will. The blown air can with increasing strength or clocked be applied.

Der Bahnmaterialgreifer 10 umfaßt einen zweiarmigen Hebel 11, der um eine Achse 12 zwischen zwei Endpositionen (in Fig. 3 dargestellt) hin- und herdrehbar ist. In der Aufnahmeposition für das Ende der Verpackungsmaterialbahn 9' liegt der Bahnmaterialgreifer 10 mit einer Rolle 13, die am freien Ende des zur Bobine 3' gerichteten Hebelarms 11' des Hebels 11 angeordnet ist, am Umfang der Bobine 3' an. Eine weitere, zur Rolle 13 parallele Rolle 14 befindet sich an einem Schlitten 15, der längs des Hebelarms 11' verschiebbar ist. Nachdem das freigelegte Ende der Verpackungsmaterialbahn 9' zwischen den beiden insbesondere mit einem Friktionsbelag versehenen Rollen 13, 14 bewegt worden ist, fährt der Schlitten 15 die Rolle 14 gegen die Rolle 13, so daß das Ende der Verpackungsmaterialbahn 9' eingeklemmt wird. (Anstelle der verschiebbaren Rolle 14 kann auch ein mit der Rolle 13 in Eingriff bringbarer Greifer vorgesehen sein.)The web material gripper 10 comprises a two-armed lever 11, the about an axis 12 between two end positions (shown in Fig. 3) is rotatable back and forth. In the shooting position for the end the packaging material web 9 'is the web material gripper 10 with a Roller 13, the free end of the lever arm directed towards the bobbin 3 ' 11 'of the lever 11 is arranged on the circumference of the bobbin 3'. Another, roller 14 parallel to roller 13 is located on a carriage 15, which is displaceable along the lever arm 11 '. After the exposed End of the packaging material web 9 'between the two in particular rollers 13, 14 provided with a friction lining have been moved, the carriage 15 moves the roller 14 against the roller 13, so that the end the packaging material web 9 'is clamped. (Instead of the sliding one Roll 14 can also be brought into engagement with the roll 13 Gripper may be provided.)

Das Andrücken der Rolle 13 des Bahnmaterialgreifers 10 an die Bobine 3' erfolgt über einen Zylinder 16, der an dem von der Bobine 3' weggerichteten Hebelarm 11'' des Hebels 11 über ein Gabelstück 17 angreift. Nach dem Ergreifen des Endes der Verpackungsmaterialbahn 9' gibt der Zylinder 16 den Hebelarm 11'' durch entsprechendes vertikales Verschieben des Gabelstücks 17 frei, so daß der Hebelarm 11' infolge eines Kontergewichts 18 am Hebelarm 11'' mit dem eingeklemmten Ende der Verpackungsmaterialbahn 9' um die Achse 12 schwenkend abwärts sinken kann.The pressing of the roll 13 of the web material gripper 10 to the Bobine 3 'takes place via a cylinder 16 which is connected to the bobbin 3' away lever arm 11 '' of the lever 11 engages via a fork 17.

In addition, a lever-shaped loop former 28 is provided, the pivotable about an axis 29 and at its free end with a baffle plate 30 (or a deflection roller) protruding at right angles is provided.

Zusätzlich sind zwei mit Abstand zueinander angeordnete Andrückrollen 31', 31'' vorgesehen, die in die Umfangsbahn des Kreiszylindersegments 21, an den Enden von entsprechenden Hebeln angeordnet, federvorgespannt sind und über die die Verpackungsmaterialbahn 9'' geführt ist.In addition, there are two pressure rollers arranged at a distance from each other 31 ', 31' 'provided in the circumferential path of the circular cylinder segment 21, arranged at the ends of corresponding levers, spring-biased are and over which the packaging material web 9 '' is.

Ferner ist ein Beleimkopf 32 vorgesehen, der in den Bereich der durch den Schlaufenbildner 28 gebildeten Schlaufe der Verpackungsmaterialbahn 9' einfahrbar ist, um auf dieser mehrere Leimraupen, etwa Heißleimraupen, aufzubringen.Furthermore, a gluing head 32 is provided which extends into the area the loop of the packaging material web formed by the loop former 28 9 'is retractable in order to have several glue beads, for example Hot glue caterpillars to apply.

Schließlich ist ein rotierenden Messer 33 vorgesehen, um die Verpackungsmaterialbahn 9'' vor dem Spleißer durchzutrennen. Das rotierende Messer 33 ist mit gleicher Umfangsgeschwindigkeit wie die Bahngeschwindigkeit der Verpackungsmaterialbahn 9'' drehbar. Das Messer 33 ist auf einem Kreisbogen in die Bahn der Verpackungsmaterialbahn 9'' zugleich um seine Achse rotierend schwenkbar. (Stattdessen kann auch ein mit einem stehenden Messer zusammenwirkendes, senkrecht zur Verpackungsmaterialbahn 9'' bewegliches Messer verwendet werden.)Finally, a rotating knife 33 is provided to the Cut the web of packaging material 9 '' in front of the splicer. The rotating Knife 33 is at the same peripheral speed as the web speed the packaging material web 9 '' rotatable. The knife 33 is on a circular arc into the path of the packaging material path 9 '' at the same time rotatable around its axis. (Instead, one with one standing knives interacting, perpendicular to the packaging material web 9 '' movable knife can be used.)

Wie aus Fig. 3 ersichtlich, ist zunächst das Kreiszylindersegment 21 von dem Gegenelement 22 derart weggeschwenkt, daß der Bahnmaterialgreifer 11, der mit seiner Rolle 13 an der Bobine 3' anliegt, zwischen diesen beiden Teilen ohne Behinderung hindurchschwenken kann. Wenn die Verpackungsmaterialbahn 9' zwischen den Rollen 13, 14 eingeklemmt ist, sinkt der Bahnmaterialgreifer 11 abwärts zwischen dem Kreiszylindersegment 21 und dem Gegenelement 22 hindurch. Die Verpackungsmaterialbahn 9' verläuft dann über die in Fig. 3 rechts oben befindliche Kante des Kreiszylindersegments 21.3, the circular cylinder segment is first 21 pivoted away from the counter element 22 such that the web material gripper 11, which rests with its roller 13 on the bobbin 3 ', between can swing these two parts through without hindrance. If the packaging material web 9 'is clamped between the rollers 13, 14 is, the web material gripper 11 sinks down between the circular cylinder segment 21 and the counter element 22 therethrough. The packaging material web 9 'then runs over the edge located at the top right in FIG. 3 of the circular cylinder segment 21.

Nachdem der Bahnmaterialgreifer 11 seine Endposition erreicht und das freie Ende der Verpackungsmaterialbahn 9' zwischen einem Abführrollenpaar 34 angeordnet hat, schwenkt das Kreiszylindersegment 21 in Richtung auf das Gegenelement 22, so daß die Verpackungsmaterialbahn 9' zwischen den beiden letztgenannten eingeklemmt wird, und zwar zwischen der Friktionsrolle 23 und ihrer Gegenfläche 24. Ferner kann die Verpackungsmaterialbahn 9' zwischen einem Teil des ebenen Abschnitt des im Schnitt halbkreisförmigen Halters 26 und einer planen Gegenfläche 35 am Kreiszylindersegment 21 (vgl. Fig. 4) zusätzlich eingeklemmt werden, jedoch kann hier auch etwas Luft sein.After the web material gripper 11 reaches its end position and the free end of the packaging material web 9 'between a pair of discharge rollers 34 has arranged, the circular cylinder segment 21 pivots in Direction towards the counter element 22, so that the packaging material web 9 ' is pinched between the latter two, between the friction roller 23 and its counter surface 24. Furthermore, the Packaging material web 9 'between part of the flat section of the in Section of semicircular holder 26 and a flat counter surface 35 am Circular cylinder segment 21 (see FIG. 4) are additionally clamped, however can be some air here.

Der Schlaufenbildner 28 schwenkt nun in die Bahn der Verpackungsmaterialbahn 9' ein und bewirkt die Bildung einer Schlaufe.The loop former 28 now swings into the path of the Packaging material web 9 'and causes the formation of a loop.

Danach fährt der Leimkopf 32 in die gebildete Schlaufe und bringt mehrere Leimraupen auf der Verpackungsmaterialbahn 9' auf (alternativ kann es sich auch um einen Kopf 32 handeln, der einen beidseitig klebenden Streifen oder beidseitig klebende Punkte aufbringt).The glue head 32 then moves into the loop and applies several glue beads on the packaging material web 9 '(alternatively it can also be a head 32, one on both sides adhesive strips or double-sided adhesive dots).

Anschließend dreht sich die Scheibe 20 mit dem Kreiszylindersegment 21 und dem Gegenelement 22 sowie der dazwischen eingeklemmten Verpackungsmaterialbahn 9' in Richtung auf die Andrückrollen 31', 31'' und damit in Richtung auf die Verpackungsmaterialbahn 9''. Die beleimte Verpackungsmaterialbahn 9' wird so über die erste Andrückrolle 31' an die Verpackungsmaterialbahn 9'' gedrückt und mit dieser verbunden.Then the disc 20 rotates with the circular cylinder segment 21 and the counter element 22 and the clamped in between Packing material web 9 'in the direction of the pressure rollers 31', 31 '' and thus in the direction of the packaging material web 9 ″. The glued Packaging material web 9 'is thus applied to the first pressure roller 31' the packaging material web 9 '' pressed and connected to it.

Vorzugsweise wird die Beleimung so vorgenommen, daß eine erste Leimraupe praktisch unmittelbar benachbart zu dem Halter 26 aufgetragen wird. Anschließend wird der Halter 26 gegen die Transportrichtung verdreht und mit einem Abschnitt benachbart zur Friktionsrolle 23 in einer entsprechenden Ausnehmung 36 im Kreiszylinderelement 21 aufgenommen. Dadurch wird ein kleiner, die erste Leimraupe tragender Abschnitt der Verpackungsmaterialbahn 9' in den so gebildeten keilförmigen Spalt zwischen Kreiszylindersegment 21 und Gegenelement 22 gezogen und daher zunächst nicht mit der Verpackungsmaterialbahn 9'' verklebt.The gluing is preferably carried out so that a first Glue bead applied practically immediately adjacent to the holder 26 becomes. Then the holder 26 is rotated against the transport direction and with a portion adjacent to the friction roller 23 in one corresponding recess 36 received in the circular cylinder element 21. Thereby becomes a small section of the packaging material web carrying the first glue bead 9 'in the wedge-shaped gap thus formed between Circular cylinder segment 21 and counter element 22 drawn and therefore initially not glued to the packaging material web 9 ''.

Im Bereich zwischen den beiden Andrückrollen 31', 31'' wird das Messer 27, das durch die Drehung des Halters 26 freigegeben wurde, betätigt, das die Verpackungsmaterialbahn 9' im Bereich der ersten Leimraupe oder unmittelbar benachbart dazu durchtrennt, wonach der Bereich der ersten Leimraupe durch die zweite Andrückrolle 31'' mit der Verpackungsmaterialbahn 9'' verklebt wird, vgl. Fig. 5. Hierzu wurde vorher der Halter 26 in seine Ausgangsposition, in der er den vorher gebildeten Spalt zwischen Kreiszylindersegment 21 und Gegenelement 22 wieder verschließt, zurückgedreht. So ergibt sich kein freier überstand der Verpackungsmaterialbahn 9', der sich entgegen der Transportrichtung hochbiegen und zu Störungen führen könnte. In the area between the two pressure rollers 31 ', 31' 'that is Knife 27, which has been released by the rotation of the holder 26, actuated, that the packaging material web 9 'in the area of the first glue bead or immediately adjacent to it, after which the area of the first Glue bead through the second pressure roller 31 '' with the packaging material web 9 '' is glued, cf. Fig. 5. For this purpose, the holder 26 in its starting position, in which it forms the previously formed gap between Circular cylinder segment 21 and counter element 22 are closed again, turned back. This means that there is no free projection of the packaging material web 9 ', which bend up and against the direction of transport Could cause interference.

Wenn kein Kleber od.dgl. wegen des Materials der Verpackungsmaterialbahnen 9', 9'' verwendet wird, kann alternativ ein Heiz-, Schweiß- oder Prägelement 37 im Bereich zwischen den beiden Andrückrollen 31', 31'' zur Einwirkung gelangen, um die beiden Verpackungsmaterialbahnen 9', 9'' miteinander zu verbinden.If no glue or the like. because of the material of the packaging material webs 9 ', 9' 'is used, alternatively a heating, Welding or embossing element 37 in the area between the two pressure rollers 31 ', 31' 'come into effect around the two packaging material webs 9 ', 9' 'to connect.

Nach dem Verbinden der Verpackungsmaterialbahnen 9', 9'' trennt das rotierende Messer 33 die Verpackungsmaterialbahn 9'' durch, während das Abführrollenpaar 34, nachdem es nach Hindurchführen des Endes der Verpackungsmaterialbahn 9' geschlossen wurde, das abgetrennte Ende abführt, nachdem das Kreiszylindersegment 21 und sein Gegenelement 22 wieder außer Eingriff gebracht sind.After connecting the packaging material webs 9 ', 9' 'separates the rotating knife 33 through the packaging material web 9 ″ while the removal roller pair 34 after it has passed through the end of the Packaging material web 9 'was closed, the separated end leads away, after the circular cylinder segment 21 and its counter element 22 again disengaged.

Das Kreiszylindersegment 21 und sein Gegenelement 22 werden durch Drehen der Scheibe 20 aus der Bahn der angespleißten Verpackungsmaterialbahn 9' herausgedreht, entsprechendes geschieht mit dem Schlaufenbildner 28, so daß die Verpackungsmaterialbahn 9' nunmehr über die Andrückrollen 31', 31'' läuft.The circular cylinder segment 21 and its counter element 22 are by rotating the disc 20 from the web of the spliced packaging material web 9 'unscrewed, the same happens with the loop former 28, so that the packaging material web 9 'now over the Pressure rollers 31 ', 31' 'runs.

Das Anspleißen kann somit bei voller Transportgeschwindigkeit der Verpackungsmaterialbahn 9'' und damit bei voller Verpackungsgeschwindigkeit der Zigarettenverpackungsmaschine vorgenommen werden. Außerdem ist der Spleißer für unterschiedliche Materialien von Verpackungsmaterial (Papier, Folie, Pappe, Verbundmaterial usw.) geeignet.The splicing can thus take place at full transport speed the packaging material web 9 '' and thus at full packaging speed the cigarette packaging machine. Furthermore is the splicer for different materials of packaging material (Paper, foil, cardboard, composite material, etc.).

Die Bobine 3' kann dann durch Drehung des Drehtellers 1 in die obere Position geschwenkt werden, ohne das der Abwickelvorgang hierdurch beeinträchtigt würde. In der oberen Position kann der verbliebene Bobinenkern 4 abgenommen und eine neue Bobine 3' angeordnet werden.The bobbin 3 'can then by rotating the turntable 1 in the the upper position can be pivoted without the unwinding process would be affected. The remaining bobbin core can be in the upper position 4 removed and a new bobbin 3 'are arranged.
