Description

Die vorliegende Erfindung betrifft eine Vorrichtung zum fortlaufenden Spenden von selbstklebenden Etiketten nach dem Oberbegriff des Patentanspruches 1.The present invention relates to a device for the continuous dispensing of self-adhesive labels according to the preamble of claim 1.

Derartige Vorrichtungen sind im Stand der Technik in unterschiedlicher Form bekannt, siehe z.B. FR-A-2 535 683. Nachteilig hat sich bei solchen Vorrichtungen jedoch bemerkbar gemacht, daß im Alltagsbetrieb ungleichmäßige Etikettenabzugskräfte entstehen, die auf das unterschiedliche Gewicht und den differierenden Durchmesser der Etikettenrolle vom Anfang bis zum Ende hin zurückzuführen sind, was zu Positionierungenauigkeiten führt. Insbesondere wird auch das Arbeiten im Hochgeschwindigkeitsbereich beeinträchtigt.Devices of this type are known in the prior art in various forms, see for example FR-A-2 535 683. A disadvantage of such devices, however, has become noticeable that uneven label pull-off forces arise in everyday operation due to the different weight and the different diameter of the label roll from the beginning to the end, which leads to positioning inaccuracies. In particular, working at high speeds is also affected.

Der Erfindung liegt deshalb die Aufgabe zugrunde, die eingangs genannte Vorrichtung derart zu verbessern, daß sie die obigen Nachteile sicher vermeidet, d.h. die Etikettenabzugskräfte sollen unabhängig vom Gewicht und Durchmesser der Etikettenrolle sein, und die Abzugsgeschwindigkeit der Etiketten soll an unterschiedlichste Bedingungen anpassbar sein, so daß auch im Hochgeschwindigkeitsbereich fortlaufend ein einwandfreies, positioniergenaues Spenden der Etiketten sichergestellt ist. Diese Aufgabe wird durch die im Anspruch 1 gekennzeichnete Vorrichtung gelöst.The invention is therefore based on the object of improving the above-mentioned device in such a way that it reliably avoids the above disadvantages, i.e. the label pull-off forces should be independent of the weight and diameter of the label roll, and the pull-off speed of the labels should be adaptable to a wide variety of conditions, so that even in the high-speed range a correct, accurate positioning of the labels is ensured. This object is achieved by the device characterized in claim 1.

Hierzu wird erfindungsgemäß eine Steuereinrichtung vorgesehen, welche ein winkelartiges Gestell mit einem Pendelarm für seine eine Achse und eine elektrisch angetriebene Welle mit Rolle für seine andere Achse aufweist. Parallel zu dieser Rolle ist eine Lichtschrankenfotozelle angeordnet, die den taktweisen Vorabzug von der Etikettenrolle ermöglicht, so daß beim Spenden immer die gleichen Abzugskräfte bestehen, und zwar unabhängig vom Durchmesser oder dem Gewicht der Etikettenrolle selbst.For this purpose, according to the invention a control device is provided which has an angular frame with a pendulum arm for its one axis and an electrically driven shaft with roller for its other axis. In parallel to this roll, a photoelectric cell is arranged, which enables the cyclical advance withdrawal from the label roll, so that the same withdrawal forces always exist when dispensing, regardless of the diameter or the weight of the label roll itself.

Ebenfalls wird erfindungsgemäß eine Klammer mit Gegendruckrollen vorgesehen, die auf der motorgetriebenen Rolle aufliegen, über die das Etikettenband verläuft. Auf diese Art und Weise wird ein einwandfreier Transport und taktweiser Vorschub von Etikett zu Etikett erreicht, der unabhängig von Gewicht und Durchmesser der Etikettenrolle gleichmäßig ist. Der Pendelarm ist schwenkbar am Gehäusearm befestigt und mit einer Feder vorgespannt. Das winkelartige Gestell ist dabei so angeordnet, daß die die Fotozelle tragende Stange angrenzend an den Außenrand der Führungsscheiben angeordnet ist.According to the invention, a clip with counter-pressure rollers is also provided, which rest on the motor-driven roller over which the label tape runs. In this way, perfect transport and intermittent feed from label to label is achieved, which is uniform regardless of the weight and diameter of the label roll. The pendulum arm is pivotally attached to the housing arm and biased with a spring. The angular frame is arranged so that the rod carrying the photocell is arranged adjacent to the outer edge of the guide disks.

Weitere Vorteile und Merkmale gehen aus den vorstehenden Unteransprüchen hervor, die auch gemeinsam mit dem Hauptanspruch von neuerungswesentlicher Bedeutung sein können.Further advantages and features emerge from the preceding subclaims, which, together with the main claim, are also essential for innovation can.

Im folgenden wird ein bevorzugtes Ausführungsbeispiel der vorliegenden Erfindung unter Bezugnahme auf die Zeichnungen gezeigt.A preferred embodiment of the present invention is shown below with reference to the drawings.

Es zeigt:

  • Fig. 1 eine schematische Querschnittsansicht der erfindungsgemäßen Vorrichtung, bei der der Pendelarm der besseren Darstellung halber weggelassen worden ist;
  • Fig. 2 eine Draufsicht auf die erfindungsgemäße Steuereinrichtung mit winkelartigem Gestell; und
  • Fig. 3 eine Querschnittsansicht des Pendelarms.
It shows:
  • Figure 1 is a schematic cross-sectional view of the device according to the invention, in which the pendulum arm has been omitted for the sake of better illustration.
  • 2 shows a plan view of the control device according to the invention with an angular frame; and
  • Fig. 3 is a cross-sectional view of the pendulum arm.

Eine erfindungsgemäße Vorrichtung zum fortlaufenden Spenden von selbstklebenden Etiketten weist eine Etikettenrolle 12 auf, die von zwei kreisrunden Führungsscheiben 41 gehalten und auf einem Lager 22 drehbar gelagert ist, das sich im oberen Bereich eines Gehäusearmes 27 befindet. Das Etikettenband 56 ist in gestrichelter Form gezeigt, wobei die Pfeile die Abzugsrichtung andeuten. Deutlich geht aus Fig. 1 hervor, wie das Etikettenband 56 um die motorgetriebene Rolle 34 herumgeführt und von einer Klammer 10 über ihre Druckrollen 44,46 fest auf die Rolle 34 gedrückt wird. Die Umlenkrollen 54 und 1 gewährleisten dabei den ungehinderten, freien Ablauf des Etikettenbandes 56 bis hin zur Spendezunge 25 mit Andruckrolle 26, wo die nicht gezeigten Etiketten vom Band gelöst und auf einen zu etikettierenden Gegenstand, beispielsweise eine Flasche oder dergleichen, übertragen werden. Der Bandverlauf im Gehäuse 23 geht dann über die Transportrolle 20 mit Gegendruckrolle 21 bis hin zur Aufspulrolle 24 für das etikettenlose Trägerband. Selbstverständlich weist eine solche Etikettiervorrichtung einen Motor 28 mit Getriebe auf, sowie ein Tastelement 60 für einen einwandfreien Etikettenabzug. Am unteren Bereich des Gehäuses 23 ist eine Haltevorrichtung 62 vorgesehen, die eine beliebige Befestigung am gewünschten Ort ermöglicht.A device according to the invention for the continuous dispensing of self-adhesive labels has a label roll 12 which is held by two circular guide disks 41 and is rotatably mounted on a bearing 22 which is located in the upper region of a housing arm 27. The label tape 56 is shown in dashed form, the arrows indicating the direction of withdrawal. 1 clearly shows how the label band 56 is guided around the motor-driven roller 34 and is pressed firmly onto the roller 34 by a clamp 10 via its pressure rollers 44, 46. The deflection rollers 54 and 1 ensure the unimpeded, free flow of the label tape 56 to the dispensing tongue 25 with the pressure roller 26, where the labels, not shown, are released from the tape and transferred to an object to be labeled, for example a bottle or the like. The course of the tape in the housing 23 then goes over the transport roller 20 with counter pressure roller 21 to the winding roller 24 for the labelless carrier tape. Of course, such a labeling device has a motor 28 with a gear and a feeler element 60 for a perfect label print. At the lower area of the housing 23, a holding device 62 is provided, which enables any attachment at the desired location.

Mit Blick auf die Fig. 2 und 3 wird nun noch näher auf das erfindungsgemäße Merkmal der Steuereinrichtung 30 eingegangen, die den gleichmäßigen Etikettenabzug und die Positioniergenauigkeit der Etiketten gewährleistet, so daß kein Versatz an der Spendezunge 25 auftritt.With reference to FIGS. 2 and 3, the feature of the control device 30 according to the invention will now be discussed in more detail, which ensures the uniform removal of the label and the positioning accuracy of the labels, so that no offset occurs on the dispensing tongue 25.

Aus Fig. 2 geht deutlich der Aufbau des winkelartigen Gestells 29 hervor, das einen schienenartigen Pendelarm 32 aufweist, der an seinem Ende im oberen Bereich des Gehäusearmes 27 mittels der Schraubeinrichtung 4 schwenkbar befestigt ist und durch eine Feder 6 vorgespannt gelagert ist. An seinem anderen Ende ist eine Welle 36 befestigt, die eine Rolle 34 aufweist, die elektrisch angetrieben wird. Parallel zur Rolle sind im geringen Abstand zwei Stangen 38 und 40 angeordnet, wobei die Stange 40 eine axial verschiebbare Fotozelle 42 aufweist, mit der die Etiketten abgetastet werden und wodurch die Taktsteuerung bewirkt wird. Auf der gegenüberliegenden Stange 38 ist die Klammer 10 mittels einer Schraubvorrichtung 65 befestigt. Die Klammer 10 ist ebenfalls axial auf der Stange 38 verschiebbar, um verschiedenen Etikettenbreiten gerecht werden zu können. Die Zugfeder 6 wird derart eingestellt bzw. mit der Verschraubung 5 befestigt, das die Stange 40 in Normalposition am Abspulteller, nämlich den Führungsscheiben 41, anliegt. Die Pendelfunktion kann mit der Drehfeder 7 optimiert werden. Durch Einstellung des Potentiometers 11 im Pendelarm 32 kann die Fotozelle 42 auf die gewünschte Stärke gebracht werden.2 clearly shows the structure of the angular frame 29, which has a rail-like pendulum arm 32, which is pivotally attached at its end in the upper region of the housing arm 27 by means of the screw device 4 and is mounted in a preloaded manner by a spring 6. At its other end a shaft 36 is attached which has a roller 34 which is electrically driven. Parallel to the roll, two rods 38 and 40 are arranged at a short distance, the rod 40 having an axially displaceable photocell 42 with which the labels are scanned and by which the clock control is effected. The clamp 10 is fastened on the opposite rod 38 by means of a screw device 65. The clip 10 is also axially displaceable on the rod 38 in order to be able to meet different label widths. The tension spring 6 is adjusted or fastened with the screw connection 5 in such a way that the rod 40 bears in the normal position on the unwinding plate, namely the guide disks 41. The pendulum function can be optimized with the torsion spring 7. By adjusting the potentiometer 11 in the pendulum arm 32, the photocell 42 can be brought to the desired strength.

Der Pendelarm 32 ist in Fig. 3 noch einmal schematisch aus anderer Sicht dargestellt. Hier ist zu sehen, daß die Klammer 10 zwei Schenkel 48 und 50 aufweist, die an ihrem hinteren Ende durch eine Feder 52 vorgespannt sind und an ihrem jeweiligen vorderen Ende eine mit Teflon (eingetragenes Warenzeichen) beschichtete Rolle 44 bzw. 46 aufweisen, die auf der elektrisch angetriebenen Rolle 34 aufliegen, um den einwandfreien und gleichmäßigen Transport des nichtgezeigten Etikettenbandes sicherzustellen.The pendulum arm 32 is shown again schematically in FIG. 3 from a different point of view. It can be seen here that the Clamp 10 has two legs 48 and 50, which are pretensioned at their rear end by a spring 52 and have a roller 44 or 46 coated with Teflon (registered trademark) at their respective front end, which rest on the electrically driven roller 34, to ensure the correct and even transport of the label tape, not shown.
