Description

Die Erfindung betrifft eine Vorrichtung zum Spenden von Etikettenhülsen nach dem Oberbegriff des Anspruchs 1, wie bekannt aus der US 4565592 A .The invention relates to a device for dispensing label sleeves according to the preamble of claim 1, as known from the US 4565592 A ,

Behälter, wie Getränkeflaschen oder dergleichen, lassen sich unter Anderem mit hülsenförmigen Etiketten ausstatten. Diese werden in einem Spendeaggregat von einem auf einer Vorratsrolle bereitgestellten Folienschlauch vorzugsweise entlang an dem Folienschlauch vorhandener Querperforationen abgerissen und über die zu etikettierenden Behälter in an sich bekannter Weise gestülpt. Die Querperforationen werden vorzugsweise mit einem dem Spendeaggregat voran geschalteten Perforieraggregat erzeugt. Für einen kontrollierten Transport des Folienschlauchs zwischen der Vorratsrolle und dem Spendeaggregat wird der Folienschlauch ferner zwischen Tensorrollen umgelenkt und unter möglichst gleichmäßiger Spannung gehalten.Containers, such as beverage bottles or the like, can be equipped, inter alia, with sleeve-shaped labels. These are demolished in a dispensing unit by a film tube provided on a supply roll, preferably along transverse perforations present on the film tube, and slipped over the containers to be labeled in a manner known per se. The transverse perforations are preferably produced with a perforating unit connected in front of the dispensing unit. For a controlled transport of the film tube between the supply roll and the dispensing unit, the film tube is further deflected between Tensorrollen and kept as uniform as possible tension.

Die US 3802152 A offenbart ferner einen Etikettenspender zum Abtrennen von Schrumpfhülsen von einem über Umlenkrollen endlos zugeführten Schrumpfschlauch. Der flachgefaltete Schrumpfschlauch wird über eine schwimmend gelagerte Metallkugel gezogen und dabei geöffnet. Als integraler Bestandteil des Etikettenspenders ist stromabwärts eine Rücklaufbremse bestehend aus miteinander verzahnten Walzen und einer Rastkupplung ausgebildet, um den Schrumpfschlauch in gezielten Portionen vorzuschieben und gleichzeitig dessen Zurücklaufen zu verhindern. Im Anschluss an die Rücklaufbremse folgt eine Schneideinrichtung zum Vereinzeln zu Schrumpfschlauchsegmenten, die der späteren Versiegelung von Verschlüssen und Halsbereichen von Behältern dienen.The US 3802152 A further discloses a label dispenser for separating shrink sleeves from a continuously supplied via deflection rollers heat shrink tubing. The flat-folded shrink tube is pulled over a floating metal ball and thereby opened. As an integral part of the label dispenser downstream a return brake is formed consisting of mutually toothed rollers and a detent coupling to advance the shrink tubing in targeted portions while preventing its retrace. Following the return brake is followed by a cutting device for singulating shrink tubing segments, which serve the subsequent sealing of closures and neck areas of containers.

Die DE 3850912 T2 offenbart ferner ein Perforieraggregat, das stromaufwärts eines Aufweitdorns ausgebildet ist, so dass sich Etikettenhülsen entlang von Querperforationen mittels Abreißwalzen vereinzeln lassen.The DE 3850912 T2 further discloses a perforating unit formed upstream of an expanding mandrel so that label sleeves can be singulated along tear perforations along transverse perforations.

Beim Abreißen der Etikettenhülsen im Spendeaggregat kann der nachlaufende Folienschlauch mechanisch so stark belastet werden, dass er insbesondere im Bereich zwischen dem Perforieraggregat und dem Spendeaggregat entlang einer Querperforation vorzeitig abreißt und von der Spanneinrichtung in den Bereich der Tensorrollen zurückgezogen wird. In der Regel löst sich der Folienschlauch dann von mehreren Rollen ab, so dass er in Transportrichtung wieder durch die Spanneinrichtung bis zum Spendeaggregat eingefädelt werden muss. Dieser Arbeitsschritt verursacht einen unerwünschten Zeitaufwand und kann zudem von einem einzelnen Bediener nicht bewältigt werden.When tearing off the label sleeves in the dispensing unit, the trailing film tube can be mechanically loaded so heavily that it breaks off prematurely in particular in the region between the perforating unit and the dispensing unit along a transverse perforation and is withdrawn by the tensioning device into the area of the tensor rolls. In general, the film tube then detached from several roles, so that it must be threaded in the transport direction again through the clamping device to the dispensing unit. This step causes an undesirable amount of time and can not be handled by a single operator.

Es besteht daher Bedarf für eine Vorrichtung zum Spenden von Etikettenhülsen, bei der sich der Produktionsbetrieb nach einem fehlerhaften Abreißen des zugeführten Folienschlauchs schneller und mit weniger Personal ordnungsgemäß fortsetzen lässt.There is therefore a need for a device for dispensing label sleeves, in which the production operation can continue properly after a faulty tearing of the supplied film tube faster and with less staff.

Die gestellte Aufgabe wird mit einer Vorrichtung gemäß Anspruch 1 gelöst. Demnach umfasst diese: ein Abrollaggregat zum Bereitstellen eines Folienschlauchs von einer Rolle; ein Spendeaggregat zum Abtrennen der Etikettenhülsen von dem Folienschlauch; und eine zwischen dem Abrollaggregat und dem Spendeaggregat ausgebildete Spanneinrichtung, mit der sich der Folienschlauch beim Transport auf Zugspannung halten lässt. Erfindungsgemäß ist zwischen der Spanneinrichtung und dem Spendeaggregat eine Rücklaufbremse für den Folienschlauch ausgebildet.The stated object is achieved with a device according to claim 1. Accordingly, it comprises: a roll-off unit for providing a film tube from a roll; a dispensing unit for separating the label sleeves from the film tube; and a clamping device formed between the rolling-off unit and the dispensing unit, with which the film tube can be held in tension during transport. According to the invention, a return brake for the film tube is formed between the tensioning device and the dispensing unit.

Die Rücklaufbremse ermöglicht ein selektives Abbremsen und/oder Festhalten des Folienschlauchs. Darunter ist zu verstehen, dass sich die Rücklaufbremse, beispielsweise in Form einer Schlauchklemme, gezielt in Abhängigkeit von einem Betriebszustand auslösen lässt und/oder permanent nur entgegen der Transportrichtung des Folienschlauchs wirkt. Letzteres lässt sich beispielsweise durch Kombination eines Vorschubfreilaufs mit einer permanenten Rücklaufsperre erzielen.The return brake allows a selective braking and / or holding the film tube. This is to be understood that the return brake, for example in the form of a hose clamp, can be triggered selectively in dependence on an operating state and / or permanently acts only counter to the transport direction of the film tube. The latter can be achieved for example by combining a feed freewheel with a permanent backstop.

Der auslösende Betriebszustand ist insbesondere ein fehlerhaftes, insbesondere vorzeitiges Abreißen des Folienschlauchs entlang einer Querperforation. Denkbar wären aber auch andere Störungen, beispielsweise im Bereich des Spendeaggregats oder im Bereich des Perforieraggregats. Die Rücklaufbremse bewirkt in jedem Fall, dass der Folienschlauch stromaufwärts der Fehlerstelle festgehalten wird, derart dass insbesondere ein abgerissenes freies Ende des Folienschlauchs nicht in die Spanneinrichtung zurück gezogen wird. Dies erleichtert zudem die Fehlerbeseitigung stromabwärts der Rücklaufbremse. Die Begriffe stromaufwärts und stromabwärts beziehen sich hierbei auf den Transport des Folienschlauchs.The triggering operating state is in particular a faulty, in particular premature tearing of the film tube along a transverse perforation. However, other disturbances would also be conceivable, for example in the area of the dispensing unit or in the area of the perforating unit. The return brake causes in each case that the film tube is held upstream of the fault, so that in particular a torn free end of the film tube is not pulled back into the clamping device. This also facilitates troubleshooting downstream of the return brake. The terms upstream and downstream refer to the transport of the film tube.

Das Abrollaggregat eignet sich in an sich bekannter Weise zum Abrollen und Vorschieben von Folienschläuchen. Der Transport durch die erfindungsgemäße Vorrichtung ist vorzugsweise kontinuierlich. Der Folienschlauch könnte auch mit den Querperforationen vorkonfektioniert auf der Rolle bereit gestellt werden. Das Spendeaggregat ist insbesondere zum Abreißen der Etikettenhülsen an vorbestimmten Trennstellen entlang der Querperforationen ausgebildet. Prinzipiell könnten die Etikettenhülsen jedoch ebenso abgeschnitten werden und/oder das Spendeaggregat für das Abreißen und Abschneiden ausgebildet sein. Die Spanneinrichtung hält den Folienschlauch vorzugsweise zwischen mehreren Tensorrollen auf Spannung, von denen wenigstens eine federnd vorgespannt ist und/oder in eine geeignete Spannstellung gefahren wird.The rolling unit is suitable in a conventional manner for unrolling and advancing film tubes. The transport through the device according to the invention is preferably continuous. The film tube could also be provided with the transverse perforations prefabricated on the roll. The dispensing unit is designed in particular for tearing off the label sleeves at predetermined separation points along the transverse perforations. In principle, however, the label sleeves could also be cut off and / or the dispensing unit designed for tearing off and cutting off. The tensioning device preferably holds the film tube between a plurality of tensor rollers, at least one of which is resiliently biased and / or driven into a suitable tensioning position.

Erfindungsgemäß verhindert die Rücklaufbremse ein Zurücklaufen des Folienschlauchs, also entgegen seiner Transportrichtung, zumindest in dem Maße, dass ein abgerissenes freies Ende des Folienschlauchs nicht vollständig durch die Rücklaufbremse zurück gezogen wird, insbesondere nicht bis in den Bereich der Spanneinrichtung, um ein Abfädeln des Folienschlauchs von den Tensorrollen zu vermeiden.According to the invention, the return brake prevents the film tube from running backward, ie counter to its transport direction, to the extent that a torn open end of the film tube is not completely pulled back through the return brake, in particular not into the area of the tensioning device, to thread the film tube from to avoid the tensor rollers.

Ferner ist zwischen der Rücklaufbremse und dem Spendeaggregat ein Perforieraggregat zum Querperforieren des Folienschlauchs vorhanden. Das Perforieraggregat befindet sich somit vorzugsweise, jedoch nicht notwendigerweise, stromabwärts der Rücklaufbremse. Auch könnte der Folienschlauch bereits vorperforiert sein. Die Rücklaufbremse ist in jedem Fall stromaufwärts eines Transportabschnitts angeordnet, in dem die Gefahr eines Abreißens durch mechanische Überbeanspruchung des Folienschlauchs besonders hoch ist, wie beispielsweise in einem Bereich unmittelbar vor dem Spendeaggregat.Furthermore, a perforating unit for transverse perforation of the film tube is present between the return brake and the dispensing unit. The perforating unit is thus preferably, but not necessarily, downstream of the return brake. Also, the film tube could already be pre-perforated. The return brake is arranged in each case upstream of a transport section in which the risk of tearing due to mechanical overstressing of the film tube is particularly high, such as in an area immediately in front of the dispensing unit.

Vorzugsweise umfasst die erfindungsgemäße Vorrichtung ferner eine Überwachungseinheit zum Feststellen eines fehlerhaften Abreißens des Folienschlauchs beim Transport und/oder eines fehlerhaften Abtrennens einer Etikettenhülse im Spendeaggregat. Die Rücklaufbremse lässt sich dann gezielt ansteuern, sobald der Folienschlauch gerissen ist oder fehlerhaft im Spendeaggregat abgeschnitten wurde. Ein Riss lässt sich an einem Nachlassen der gemessenen Schlauchspannung im abgerissenen, nachlaufenden Folienschlauch feststellen und/oder daran, dass der Folienschlauch in einem bestimmten Bereich stromabwärts der Rücklaufbremse nicht mehr vorhanden ist. Auch ein fehlerhaftes Abschneiden einer Etikettenhülse, das ein Zurückziehen des nachlaufenden Folienschlauchs zur Folge haben könnte, lässt sich auf die gleiche Weise erkennen, um die Rücklaufbremse gezielt anzusteuern.Preferably, the device according to the invention further comprises a monitoring unit for detecting a faulty tearing of the film tube during transport and / or a faulty separation of a label sleeve in the dispensing unit. The return brake can then be targeted to control as soon as the film tube is torn or was incorrectly cut off in the dispensing unit. A crack can be detected by a decrease in the measured hose tension in the torn, trailing film hose and / or the fact that the film hose in a certain area downstream of the return brake is no longer present. Even a faulty cutting of a label sleeve, which could have a retraction of the trailing film tube result, can be seen in the same way to selectively control the return brake.

Vorzugsweise umfasst die Überwachungseinheit einen Spannungsdetektor zum Messen einer Zugspannung im Folienschlauch, also einer durch den Transport und das Aufspannen erzeugten mechanischen Spannung. Damit ließe sich ein drohender oder vorhandener Riss des Folienschlauchs auch dann zuverlässig feststellen, wenn sich der Riss stromabwärts des Spannungsdetektors ereignet. Eine solche Erkennung ist besonders schnell, da das abgerissene Schlauchende für eine Fehlererkennung nicht bis zum Detektor zurücklaufen muss.Preferably, the monitoring unit comprises a voltage detector for measuring a tensile stress in the film tube, that is, a mechanical stress generated by the transport and the clamping. Thus, a threatening or existing crack of the film tube could be reliably detected even if the crack occurs downstream of the voltage detector. Such a detection is particularly fast, since the torn-off hose end does not have to run back to the detector for error detection.

Die Zugspannung kann sich in den einzelnen Transportabschnitten der erfindungsgemäßen Vorrichtung in unterschiedlichem Maße aus Anteilen zusammensetzen, die vom Transport des Folienschlauchs, dem Aufspannen des Folienschlauchs in der Spanneinrichtung und/oder dem Abreißen der Folienhülsen im Spendeaggregat verursacht werden. Eine Spannungsmessung könnte auch stromaufwärts der Rücklaufbremse hilfreich sein, beispielsweise im Bereich der Spanneinrichtung, um die Rücklaufbremse besonders zuverlässig auszulösen. Mit einem Spannungsdetektor lässt sich die Rücklaufbremse selektiv auslösen, sobald die im Folienschlauch gemessene Spannung einen für den jeweiligen Transportabschnitt vorgegebenen Mindestwert unterschreitet oder ein anderes geeignetes Vergleichskriterium erfüllt.The tension can be composed in the individual transport sections of the device according to the invention to varying degrees from shares that are caused by the transport of the film tube, the clamping of the film tube in the clamping device and / or the tearing of the film sleeves in the dispensing unit. A voltage measurement could also be helpful upstream of the return brake, for example in the area of the tensioning device, in order to trigger the return brake particularly reliably. With a voltage detector, the return brake can be triggered selectively as soon as the voltage measured in the film tube falls below a minimum value specified for the respective transport section or fulfills another suitable comparison criterion.

Vorzugsweise umfasst die Überwachungseinheit einen optischen Detektor zum Abtasten des Folienschlauchs. Damit lässt sich das Vorhandensein des Folienschlauchs auf einfache Weise berührungslos feststellen. Fehlt der Folienschlauch bei laufendem Transport, kann auf ein fehlerhaftes Abreißen des Folienschlauchs geschlossen werden. Der optische Detektor kann beispielsweise als Transmissionslichtschranke oder Reflexionslichtschranke ausgebildet sein. Ebenso denkbar wäre eine Bild gebende Überwachung des Folienschlauchs.Preferably, the monitoring unit comprises an optical detector for scanning the film tube. This makes it possible to determine the presence of the film tube in a simple manner without contact. If the film tube is missing during transport, it can be concluded that the film tube tears off incorrectly. The optical detector can be designed, for example, as a transmission light barrier or reflection light barrier. Also conceivable would be an image-giving monitoring of the film tube.

Vorzugsweise umfasst die Überwachungseinheit wenigstens einen Detektor zum Überwachen des Folienschlauchs stromabwärts der Rücklaufbremse, beispielsweise im Eingangsbereich des Spendeaggregats. Insbesondere werden die Zugspannung und/oder das Vorhandensein des Folienschlauchs überwacht.Preferably, the monitoring unit comprises at least one detector for monitoring the film tube downstream of the return brake, for example in the entrance area of the dispensing unit. In particular, the tension and / or the presence of the film tube are monitored.

Vorzugsweise umfasst die Überwachungseinheit wenigstens einen Detektor zum Überwachen des Folienschlauchs stromabwärts des Perforationsaggregats, beispielsweise im Eingangsbereich des Spendeaggregats. Ein fehlerhafter Riss des Folienschlauchs lässt sich dann besonders zuverlässig erkennen.Preferably, the monitoring unit comprises at least one detector for monitoring the film tube downstream of the perforation unit, for example in the entrance area of the dispensing unit. A faulty tear of the film tube can then be detected particularly reliably.

Vorzugsweise umfasst die Rücklaufbremse eine aktiv steuerbare Klemme. Beispielsweise lässt sich wenigstens ein Klemmbacken in Abhängigkeit von einem festgestellten fehlerhaften Abreißen des Folienschlauchs gegen den zurücklaufenden Folienschlauch fahren, schwenken oder dergleichen. Die Rücklaufbremse hält den Folienschlauch dann sowohl in als auch entgegen der Transportrichtung fest.Preferably, the return brake comprises an actively controllable terminal. For example, at least one clamping jaw can be driven, pivoted or the like depending on a detected faulty tearing off of the film tube against the returning film tube. The return brake then holds the film tube firmly both in and against the transport direction.

Vorzugsweise ist die Klemme pneumatisch angetrieben, insbesondere mittels eines pneumatischen Hubzylinders. Beispielsweise lässt sich ein beweglicher Klemmbacken dann schnell gegen einen stationären Klemmbacken, eine Führungsrolle oder dergleichen fahren, um den Folienschlauch fest zu halten.Preferably, the clamp is pneumatically driven, in particular by means of a pneumatic lifting cylinder. For example, a movable jaw can then quickly travel against a stationary jaw, guide roller or the like to hold the film tube tight.

Vorzugsweise umfasst die Rücklaufbremse ein in Transportrichtung des Folienschlauchs freilaufendes Reibrad mit einer Rücklaufsperre. Beispielsweise könnte der Folienschlauch zwischen zwei Klemmrollen hindurch laufen, von denen eine an eine Rücklaufsperre gekoppelt ist. Das heißt der Folienschlauch wird dann im Wesentlichen nur entgegen der Transportrichtung gebremst. Eine derartige Rücklaufbremse wäre gegebenenfalls auch ohne zusätzliche Überwachungseinheit permanent wirksam.Preferably, the return brake comprises a free-running in the transport direction of the film tube friction wheel with a backstop. For example, the film tube could pass between two pinch rollers, one of which is coupled to a backstop. That is, the film tube is then braked substantially only against the transport direction. If necessary, such a return brake would be permanently effective even without an additional monitoring unit.

Vorzugsweise ist das Spendeaggregat zum Abtrennen der Etikettenhülsen durch Abreißen entlang an dem Folienschlauch ausgebildeter Querperforationen ausgebildet. Bei diesen hinsichtlich der Konstruktion und des Verschleißes vorteilhaften Aggregaten wird der Folienschlauch in Längsrichtung stark beansprucht, so dass eine Rücklaufbremse bei fehlerhaftem Abreißen entlang der Perforationen in besonderem Maße Kosten und Zeit spart.Preferably, the dispensing unit for separating the label sleeves is formed by tearing along formed on the film tube transverse perforations. In these advantageous in terms of construction and wear aggregates of the film tube is heavily stressed in the longitudinal direction, so that a return brake in faulty tearing along the perforations saves in particular costs and time.

Bei einer weiteren günstigen Ausführungsform ist das Spendeaggregat zum Abschneiden der Folienhülsen von dem Folienschlauch ausgebildet. Dadurch lässt sich die beim Abtrennen der Etikettenhülsen verursachte Zugspannung reduzieren.In a further advantageous embodiment, the dispensing unit is designed for cutting off the film sleeves of the film tube. This can reduce the tension caused when separating the label sleeves.

Vorzugsweise umfasst die Spanneinrichtung wenigstens eine federnd vorgespannte Tensorrolle zum Umlenken und Spannen des Folienschlauchs. Derartige Tensorrollen ermöglichen ein zuverlässiges Einhalten einer vorgegebenen Zugspannung im Folienschlauch, ziehen einen abgerissenen Folienschlauchs jedoch bei herkömmlichen Vorrichtungen in den Bereich der Spanneinrichtung zurück, wo das Wiedereinfädeln des Schlauchs einen besonders hohen Arbeitsaufwand verursacht. Somit ist die erfindungsgemäße Rücklaufbremse stromabwärts der Tensorrollen besonders vorteilhaft.Preferably, the clamping device comprises at least one resiliently biased Tensorrolle for deflecting and tensioning the film tube. Such Tensorrollen allow a reliable compliance with a predetermined tension in the film tube, pull a demolished Foil tube, however, in conventional devices back to the area of the clamping device, where the re-threading of the hose causes a particularly high workload. Thus, the return brake according to the invention downstream of the tensor rollers is particularly advantageous.

Die gestellte Aufgabe wird ebenso mit einer Etikettiervorrichtung für Behälter, insbesondere Flaschen, gelöst, die die erfindungsgemäße Vorrichtung umfasst. Derartige Etikettiervorrichtungen arbeiten vorzugsweise unter kontinuierlichem und vergleichsweise schnellem Transport des Folienschlauchs, so dass ein zeitnahes und ergonomisch günstiges Wiederaufnehmen des Produktionsbetriebs von besonderer Bedeutung ist.The stated object is also achieved with a labeling device for containers, in particular bottles, which comprises the device according to the invention. Such labeling preferably operate under continuous and comparatively fast transport of the film tube, so that a timely and ergonomically favorable resumption of the production operation is of particular importance.

Eine bevorzugte Ausführungsform der Erfindung ist in der einzigen Figur schematisch dargestellt.A preferred embodiment of the invention is shown schematically in the single figure.

Demnach umfasst die erfindungsgemäße Vorrichtung 1 zum Spenden von Etikettenhülsen 2 auf Behälter 3, wie beispielsweise Getränkeflaschen, ein Abrollaggregat 4 zum Bereitstellen eines Folienschlauchs 5 von einer Rolle 6. Der Folienschlauch 5 wird vorzugsweise in einem Perforieraggregat 7 quer zur Transportrichtung 8 des Folienschlauchs 5 perforiert. Entlang von Querperforationen 9 lassen sich die Etikettenhülsen 2 dann in einem Spendeaggregat 10 abreißen und über die Behälter 3 stülpen. Dies ist an sich bekannt und daher nachfolgend nicht näher erläutert. Prinzipiell könnte der Folienschlauch 5 auch vorkonfektioniert mit den Querperforationen 9 auf der Rolle 6 bereit gestellt werden. Ebenso könnten die Etikettenhülsen 2 in dem Spendeaggregat 10 mittels an sich bekannter Schneiden abgeschnitten werden, beispielsweise entlang einer Schnittlinie entsprechend der in der Figur mit Pfeil bezeichneten Querperforation 9.Accordingly, the device 1 according to the invention for dispensing label sleeves 2 on containers 3, such as beverage bottles, a roll-off unit 4 for providing a film tube 5 from a roll 6. The film tube 5 is preferably perforated in a perforating 7 transverse to the transport direction 8 of the film tube 5. Along transverse perforations 9, the label sleeves 2 can then be torn off in a dispensing unit 10 and put over the container 3. This is known per se and therefore not explained in detail below. In principle, the film tube 5 could also be provided ready-made with the transverse perforations 9 on the roll 6. Likewise, the label sleeves 2 could be cut in the dispensing unit 10 by means of known per se, for example, along a section line corresponding to the designated in the figure with arrow transverse perforation. 9

Zwischen dem Abrollaggregat 4 und dem Spendeaggregat 10 ist eine Spanneinrichtung 11 mit Tensorrollen 12 vorhanden. Mit einer schematisch angedeuteten Druckfeder 13, dergleichen elastischer Elemente und/oder einem Stellantrieb wird der Folienschlauch 5 während seines Transports auf geeigneter Zugspannung gehalten.Between the unwinding unit 4 and the dispensing unit 10, a clamping device 11 with tensor rolls 12 is present. With a schematically indicated compression spring 13, the like elastic elements and / or an actuator of the film tube 5 is held during its transport at a suitable tension.

Erfindungsgemäß ist zwischen der Spanneinrichtung 11 und dem Spendeaggregat 10 eine Rücklaufbremse 14 vorhanden, mit der sich der Folienschlauch 5 gezielt festhalten lässt. Dadurch lässt sich vermeiden, dass ein fehlerhaft abgerissenes freies Ende 5a des Folienschlauchs 5 in die Spanneinrichtung 11 zurück gezogen wird, und dass sich der Folienschlauch 5 dabei von den Tensorrollen 12 ablöst.According to the invention, a return brake 14 is present between the tensioning device 11 and the dispensing unit 10, with which the film tube 5 can be selectively held. As a result, it is possible to prevent a faulty torn-off free end 5a of the film tube 5 from being pulled back into the tensioning device 11, and that the film tube 5 thereby separates from the tensor rollers 12.

Die Rücklaufbremse 14 umfasst vorzugsweise wenigstens einen beweglichen Klemmbacken 15, dessen Schließbewegung 16 gegen einen zugehörigen stationären Klemmbacken oder dergleichen gezielt in Abhängigkeit von einem fehlerhaften Betriebszustand, bei einer Produktionsunterbrechung oder dergleichen, ausgelöst wird. Für den Antrieb des Klemmbackens 15 ist beispielsweise ein pneumatischer Zylinder 17, ein elektromagnetischer Stellantrieb oder dergleichen vorgesehen. Ebenso wäre eine Zange mit paarweise beweglichen Klemmbacken 15 möglich (nicht dargestellt).The return brake 14 preferably comprises at least one movable jaw 15, the closing movement 16 of which is triggered against an associated stationary jaw or the like in response to a faulty operating state, a production interruption or the like. For the drive of the jaw 15, for example, a pneumatic cylinder 17, an electromagnetic actuator or the like is provided. Likewise, a pair of pliers with movable jaws 15 in pairs would be possible (not shown).

Alternativ oder ergänzend kann die Rücklaufbremse 14 wenigstens ein am Folienschlauch 5 anliegendes Reibrad 18 oder dergleichen mit einem Vorschubfreilauf und einer schematisch angedeuteten Rücklaufsperre 19 umfassen. Die Rücklaufbremse 14 wirkt dann selektiv entgegen der Transportrichtung 8 durch Reibschluss mit dem Folienschlauch 5. Eine derartige Rücklaufsperre wäre prinzipiell auch wirksam, ohne die Integrität des Folienschlauchs 5 mittels separater Detektoren zu überwachen, also ohne Ansteuerung der Rücklaufbremse 14 von außen.As an alternative or in addition, the return brake 14 may comprise at least one friction wheel 18 or the like resting against the film tube 5, with a feed freewheel and a backstop 19 indicated schematically. The return brake 14 then acts selectively against the transport direction 8 by frictional engagement with the film tube 5. Such a backstop would in principle also be effective without monitoring the integrity of the film tube 5 by means of separate detectors, ie without controlling the return brake 14 from the outside.

In der Figur ist schematisch ein Abreißen des Folienschlauchs 5 entlang einer Querperforation 9 am Eingang des Spendeaggregats 10 dargestellt. In diesem Bereich wird der Folienschlauch 5 beim Abreißen einzelner Etikettenhülsen 2 besonders stark durch Zug in Längsrichtung belastet. Zur Kontrolle der Integrität des Folienschlauchs 5 ist vorzugsweise eine Überwachungseinheit 21 vorhanden, die beispielsweise wenigstens einen Spannungsdetektor 22 und/oder wenigstens einen optischen Detektor 23 umfasst.In the figure, a tearing of the film tube 5 is shown schematically along a transverse perforation 9 at the entrance of the dispensing unit 10. In this area, the film tube 5 is particularly heavily loaded by tearing in the longitudinal direction when tearing off individual label sleeves 2. To control the integrity of the film tube 5, a monitoring unit 21 is preferably present, which comprises, for example, at least one voltage detector 22 and / or at least one optical detector 23.

Der Spannungsdetektor 22 ist vorteilhaft, da sich auch ein Abreißen des Folienschlauchs 5 stromabwärts des Spannungsdetektors 22 anhand eines charakteristischen Rückgangs der gemessenen Zugspannung erkennen lässt, also bereits bevor das abgerissene nachlaufende Ende 5a des Folienschlauchs 5 bis zum Spannungsdetektor 22 zurück gezogen worden ist. Folglich kann ein Steuersignal 24 zum Auslösen der Rücklaufbremse 14 mit kurzer Reaktionszeit erzeugt werden.The voltage detector 22 is advantageous because it is also possible to detect a tearing off of the film tube 5 downstream of the voltage detector 22 on the basis of a characteristic decrease in the measured tensile stress, ie even before the torn off trailing end 5a of the film tube 5 has been pulled back to the voltage detector 22. Consequently, a control signal 24 for triggering the return brake 14 can be generated with a short reaction time.

Mit dem optischen Detektor 23, der beispielsweise als Transmissionslichtschranke oder Reflexionslichtschranke (nicht dargestellt) ausgebildet sein kann, lässt sich das Vorhandensein des Folienschlauchs 5 besonders zuverlässig überwachen. Fehlt der Folienschlauch 5 im Messbereich des optischen Detektors 23, so wird auf ein fehlerhaftes Abreißen des Folienschlauchs 5 geschlossen und das Steuersignal 24 erzeugt. Die Lage des Spannungsdetektors 22 und des optischen Detektors 23 in der Figur sind lediglich beispielhaft.With the optical detector 23, which may be formed, for example, as a transmission light barrier or reflection light barrier (not shown), the presence of the film tube 5 can be monitored particularly reliably. If the film tube 5 is missing in the measuring range of the optical detector 23, an erroneous tearing off of the film tube 5 is concluded and the control signal 24 is generated. The location of the voltage detector 22 and the optical detector 23 in the figure are merely exemplary.

Allerdings ist eine optische Überwachung im Transportbereich zwischen Perforieraggregat 7 und Spendeaggregat 10 besonders vorteilhaft, da dort ein fehlerhaftes Abreißen und somit ein Fehlen des Folienschlauchs 5 am wahrscheinlichsten ist. Außerdem ist eine optische Überwachung weitgehend unabhängig von Schwankungen der Zugspannung, die beim Abreißen der Etikettenhülsen 2 auftreten.However, optical monitoring in the transport area between the perforating unit 7 and the dispensing unit 10 is particularly advantageous, since there is a faulty tearing and thus a Absence of the film tube 5 is most likely. In addition, an optical monitoring is largely independent of variations in the tension that occur when tearing off the label sleeves 2.

Eine Überwachung der Zugspannung im Folienschlauch 5 ist im Transportbereich zwischen Rücklaufbremse 14 und Perforieraggregat 7 besonders vorteilhaft, da das abgetrennte Ende 5a des Folienschlauchs 5 für eine Fehlererkennung nicht erst bis zum Spannungsdetektor 22 zurück laufen muss. Prinzipiell wäre eine Überwachung der Zugspannung im Folienschlauch 5 sogar stromaufwärts der Rücklaufbremse 14 denkbar, sofern ein fehlerhaftes Abreißen stromabwärts der Rücklaufbremse 14 einen geeigneten Rückgang der Zugspannung am Spannungsdetektor 22 verursacht.A monitoring of the tension in the film tube 5 is particularly advantageous in the transport area between return brake 14 and perforating unit 7, since the severed end 5a of the film tube 5 does not have to run back to the voltage detector 22 for fault detection. In principle, a monitoring of the tension in the film tube 5 even upstream of the return brake 14 would be conceivable, provided that a faulty tearing downstream of the return brake 14 causes a suitable decrease in the tension on the voltage detector 22.

In jedem Fall wird die Rücklaufbremse 14 ausgelöst, bevor das abgetrennte Ende 5a des Folienschlauchs 5 durch die Rücklaufbremse 14 zurück gezogen worden ist. Durch rechtzeitiges Auslösen der Rücklaufbremse 14 lässt sich verhindern, dass sich der Folienschlauch 5 von den Tensorrollen 12 ablöst, so dass für ein Wiederaufnehmen der Etikettierung lediglich der Folienschlauch 5 im Bereich stromabwärts der Rücklaufbremse 14 erneut eingefädelt werden muss.In any case, the return brake 14 is triggered before the severed end 5a of the film tube 5 has been pulled back by the return brake 14. Timely triggering of the return brake 14 can prevent the film tube 5 from detaching from the tensor rollers 12, so that only the film tube 5 has to be threaded again in the area downstream of the return brake 14 for resuming the labeling.

Die erfindungsgemäße Vorrichtung 1 ist vorzugsweise Bestandteil einer an sich bekannten Etikettiervorrichtung 30 zum Etikettieren der Behälter 3 mit den Folienhülsen 2. Eine derartige Etikettiervorrichtung 30 umfasst beispielsweise ein Etikettierkarussell 31, mit dem die Behälter 3 als kontinuierlicher Produktstrom unter dem stationären Spendeaggregat 10 hindurch gefahren werden. Die Drehachse 32 des Etikettierkarussells 31 ist in der Figur schematisch angedeutet. Der Transport des Folienschlauchs 5 durch die erfindungsgemäße Vorrichtung 1 ist somit vorzugsweise kontinuierlich und erfolgt in an sich bekannter Weise, so dass Einzelheiten hierzu nicht näher erläutert oder dargestellt sind.The device 1 according to the invention is preferably part of a labeling device 30 known per se for labeling the containers 3 with the film sleeves 2. Such a labeling device 30 comprises, for example, a labeling carousel 31, with which the containers 3 are driven as a continuous product stream under the stationary dispensing unit 10. The axis of rotation 32 of the labeling carousel 31 is schematically indicated in the figure. The transport of the film tube 5 by the device 1 according to the invention is therefore preferably continuous and takes place in a manner known per se, so that details of this are not explained or illustrated in detail.

Die schematisch angedeuteten Ausführungsformen der Rücklaufbremse 14 ließen sich sowohl einzeln als auch in Kombination beliebig im Bereich zwischen der Spanneinrichtung 11 und dem Spendeaggregat 10 einsetzen. Die ausgelöste/wirksame Rücklaufbremse 14 kann den Folienschlauch 5 fest halten und/oder einen langsamen Rücklauf des Folienschlauchs 5 zulassen, sofern ein Zurücklaufen des freien Endes 5a des Folienschlauchs 5 durch die Rücklaufbremse 14 hindurch verhindert wird.The schematically indicated embodiments of the return brake 14 could be used either individually or in combination as desired in the area between the clamping device 11 and the dispensing unit 10. The triggered / effective return brake 14 can hold the film tube 5 firmly and / or allow a slow return of the film tube 5, provided that a running back of the free end 5a of the film tube 5 is prevented by the return brake 14 therethrough.
