Description

Die Erfindung betrifft eine Vorrichtung zum Siegeln einer Pak­ kungshülle von Packungen, insbesondere einer Folienumhüllung von Zigarettenpackungen, mit sich gegenüberliegenden, die Pak­ kungen im Bereich ihrer Verschlußfläche mit Anlagedruck erfas­ senden und an ihrer den Packungen abgewendeten Innenseite durch Siegelorgane beaufschlagbaren, umlaufenden Siegelbändern.The invention relates to a device for sealing a pak kungshülle of packs, especially a film wrapping of cigarette packs, with opposing ones, the pak conditions in the area of their closure surface with system pressure send and through on the inside facing away from the packs Sealing organs acted upon, surrounding sealing tapes.

Vorrichtungen der eingangs bezeichneten Gattung sind in der Regel Bestandteile sogenannter Cellophaniermaschinen, auf denen beispielsweise die Faltlappen bzw. Schließlappen von Außenum­ hüllungen aus Kunststoff-Folien (Polyäthylen etc.) mittels be­ heizter Siegelorgane durch thermische Verschweißung miteinander verbunden werden.Devices of the type mentioned are in the Rule components of so-called cellophane machines on which for example the folding flaps or closing flaps from the outside envelopes made of plastic films (polyethylene etc.) using be heated sealing elements by thermal welding to each other get connected.

Im kontinuierlichen Betrieb derartiger Vorrichtungen haben sich relativ dünne Siegelbänder bewährt, die einerseits den Trans­ port der zu siegelnden Packungen durch die Siegelstrecke unter­ stützen und andererseits die durch die Siegelorgane bzw. Sie­ gelbacken erzeugte Heizleistung möglichst verlust- und verzöge­ rungsfrei an die Faltlappen übertragen.In the continuous operation of such devices Relatively thin sealing tapes that have proven the Trans port of the packs to be sealed through the sealing section below support and on the other hand through the sealing organs or you Gel-baked heat output generated loss and delay as possible transfer to the folding tabs without

Es hat sich gezeigt, daß insbesondere bei der Cellophanierung relativ steifer bzw. unnachgiebiger, quaderförmiger Hinged-Lid- Packungen schon geringe Größenunterschiede, insbesondere über­ größen der Packungen, zur vorzeitigen Deformierung und Zerstö­ rung der empfindlichen Siegelbänder führen können.It has been shown that especially in cellophane relatively stiff or unyielding, cuboid hinged lid Packs already small size differences, especially about sizes of the packs, for premature deformation and destruction sensitive sealing tapes.

Der Erfindung liegt die Aufgabe zugrunde, Maßnahmen zum scho­ nenden Betrieb und damit zur Standzeiterhöhung der Siegelbän­ der zu treffen.The invention has for its object measures to scho operation and thus to increase the service life of the sealing tapes the to meet.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß zwischen den Siegelbändern und den Siegelorganen eine die Siegelorgane überbrückende Folienabdeckung vorgesehen ist. This object is achieved in that between the sealing tapes and the sealing organs one the sealing organs bridging foil cover is provided.  

Als für den schonenden Betrieb der Siegelbänder besonders wirk­ sam hat sich nach einer Weiterbildung eine Folienabdeckung erwiesen, die als entlang der Siegelstrecke hinter den Siegel­ bändern angeordnetes stationäres Vorlegeband ausgebildet ist.Particularly effective for the gentle operation of the sealing tapes sam has a film cover after further training proven to be along the seal path behind the seal bands arranged stationary feed tape is formed.

Ein optimaler Gleit- und Stützeffekt für die Siegelbänder läßt sich gemäß einer vorteilhaften Ausgestaltung dadurch erreichen, daß das Vorlegeband an Spannorganen befestigt ist. Zweckmäßigerweise ist das Vorlegeband über eine Einlauf- bzw. eine Auslaufschräge der Siegelstrecke hinweggeführt. Gemäß einer Fortbildung sind die Spannorgane als verdrehbare und arretierbare Spannklötze ausgebildet.An optimal sliding and support effect for the sealing tapes according to an advantageous embodiment, that the tape is attached to tensioning elements. The feed tape is expediently fed over an infeed or a run-off slope of the sealing section led away. According to a further training, the tensioning elements are rotatable and lockable clamping blocks.

Der mit der Erfindung erzielte Vorteil besteht darin, daß das aus Kunststoff oder Metall bestehende gespannte Vorlegeband eine Stütz- und Gleitfunktion für das sehr dünne, vorzugsweise aus Stahl bestehende Siegelband ausübt, daß damit von örtlichen Verwerfungen verschont und dessen Funktionsfähigkeit demzufolge unbeeinträchtigt bleibt, was eine deutliche Standzeitverlänge­ rung bedeutet.The advantage achieved with the invention is that tensioned covering tape made of plastic or metal a support and slide function for the very thin, preferably steel sealing tape exerted by local Faults are spared and consequently its functionality remains unaffected, which is a significant increase in tool life tion means.

Die Erfindung wird nachstehend anhand des in der beigefügten Abbildung dargestellten Ausführungsbeispiels näher erläutert.The invention is illustrated below in the attached Figure illustrated embodiment explained in more detail.

Die Figur zeigt in der Draufsicht eine Siegelvorrichtung zum Siegeln von Kopf- und Bodenschluß der Folienumhüllung von Ziga­ rettenpackungen.The figure shows a top view of a sealing device for Sealing the top and bottom of Ziga's film wrapping rescue packs.

Die zu siegelnden Zigarettenpackungen 1 werden kontinuierlich mit einem definierten Teilungsabstand durch Anschlagleisten 2 eines Förderbandes 3 in Richtung des Pfeils 4 in die Siegel­ strecke eingeführt. Die Siegelstrecke ist durch zwei sich gegenüberliegende, dünne, endlose Siegelbänder 6 aus Stahl be­ grenzt, welche mittels Umlenkrollen 7 umlaufend geführt sind, von denen zwei von einem nicht gezeigten Motor über eine Kupplung 8 antreibbar sind.The cigarette packs 1 to be sealed are continuously introduced at a defined pitch by stop strips 2 of a conveyor belt 3 in the direction of arrow 4 into the sealing section. The sealing section is bordered by two opposing, thin, endless sealing strips 6 made of steel, which are guided circumferentially by means of deflection rollers 7 , two of which can be driven by a motor (not shown) via a clutch 8 .

Die Innenseite der einander zugewandten, die Packungen 1 mit Anlagedruck erfassenden Trume der Siegelbänder 6 sind durch beheizte Siegelorgane in Form von entlang der Siegelstrecke nebeneinanderliegenden Siegelbacken 9 beaufschlagbar, die mit­ tels Pneumatikzylindern 11 quer zur Förderrichtung (Pfeil 4) der Packungen 1 gegen die Siegelbänder 6 anstellbar sind.The inside of the facing, the packs 1 detected with system pressure strands of the seal bands 6 can be acted upon by heated sealing means in the form of side by side along the seal line sealing jaws 9, which transversely with means of pneumatic cylinders 11 to the conveying direction (arrow 4) of the packs 1 against the seal bands 6 are employable.

Zwischen den Siegelbacken 9 und den Siegelbändern 6 verläuft eine die Siegelbacken überbrückende Folienabdeckung in Form eines stationären Vorlegebandes 12, welches zwischen Spannorga­ nen in Form eines festen Spannklotzes 13 und eines verdrehbaren sowie mittels einer Verschraubung 14 arretierbaren Spannklotzes 16 straff eingespannt ist. Das aus Kunststoff oder Metall be­ stehende Vorlegeband 12 ist jeweils über schräge Einlaufschuhe 17 bzw. schräge Auslaufschuhe 18 herumgezogen.Between the sealing jaws 9 and the sealing strips 6 , a sealing covering bridging the sealing jaws runs in the form of a stationary supporting tape 12 which is clamped tight between clamping organs in the form of a fixed clamping block 13 and a rotatable clamping block 16 which can be locked by means of a screw connection 14 . The plastic or metal support tape 12 is pulled over inclined run-in shoes 17 or inclined run-out shoes 18 .

Das straff gespannte, stationäre Vorlegeband 12 verhindert bei Maßabweichungen der Packungen 1 bezüglich des auf eine be­ stimmte Formatbreite zwischen den Siegelbändern 6 eingestellten Abstandes örtliche Verformungen und daraus entstehende vor­ zeitige Zerstörungen der Siegelbänder 6. Zur Einstellung der jeweiligen Formatbreite sind die Siegelorgane auf am Maschinen­ gehäuse 19 gelagerten Trägern 21 relativ zueinander quer ver­ schiebbar.The tightly tensioned, stationary supply tape 12 prevents dimensional deviations in the packs 1 with respect to the set to a certain format width between the sealing tapes 6 distance local deformations and the resulting premature destruction of the sealing tapes 6th To set the respective format width, the sealing members on the machine housing 19 mounted supports 21 are relatively slidable ver relative to each other.
