Description
Die vorliegende Erfindung betrifft eine Etikettiervorrichtung zum Etikettieren von Gegenständen, insbesondere von Getränkekisten" mit Etiketten, die mit einer Klebebeschichtung versehen sind, wobei die Etikettiervorrichtung eine Fördereinrichtung zum Fördern der zu etikettierenden Gegenstände, eine Etikettenzuführeinrichtung zum Bereitstellen und Anbringen von einzelnen mit einer Klebebeschichtung versehen Etiketten an den zu etikettierenden Gegenständen, und eine Andrückeinrichtung zum Andrücken der an den zu etikettierenden Gegenständen angebrachten Etiketten umfasst, wie im Oberbegriff von Anspruch 1 angegeben.The present invention relates to a labeling device for labeling articles, in particular beverage crates, with labels provided with an adhesive coating, the labeling device comprising a conveyor for conveying the articles to be labeled, a label supply device for providing and applying individual labels provided with an adhesive coating on the articles to be labeled, and a pressing device for pressing the labels attached to the articles to be labeled comprises, as indicated in the preamble of
Derartige Etikettiervorrichtungen sind bereits aus dem Stand der Technik bekannt. So beschreibt das Dokument
Ferner zeigt das Dokument
Ferner ist eine derartige Anordnung nur für bestimmte Getränkekisten mit relativ großflächigen zu beklebenden Oberflächen geeignet Dies liegt daran, dass die Massiereinrichtung aufgrund der an dieser vorbeigeförderten Getränkekiste immer einen relativ großen Flächebereich erfasst. Damit sind die Anwendungsmöglichkeiten einer derartigen Etikettiervorrichtung stark eingeschränkt und nur auf bestimmte Getränkekistentypen begrenzt. Heutzutage kommen aber eine Vielzahl verschiedener Getränkekistentypen zum Einsatz, die allesamt automatisiert mit hoher Qualität zu etikettieren sind.Furthermore, such an arrangement is suitable only for certain beverage crates with relatively large surfaces to be bonded surfaces. This is because the massaging device always detects a relatively large area due to the crate conveyed past it. Thus, the applications of such a labeling device are severely limited and limited to certain types of beverage crates. Today, however, come a variety of different crate types all of which are automatically labeled with high quality.
Zur Etikettierung von Getränkekisten gibt es eine Reihe weiterer Lösungen im Stand der Technik. Hierzu wird beispielsweise auf das Dokument
Darüber hinaus beschreibt das Dokument
Neben der Etikettierung der Trägerkisten besteht ein weiterer Aspekt der Erfindung darin, die einmal etikettierten Kisten nach einem Rücklauf von alten Etiketten zu befreien. Dies geschieht natürlich vor der erneuten Etikettierung.In addition to the labeling of the carrier boxes, another aspect of the invention is to free the once labeled boxes after a return of old labels. Of course, this happens before re-labeling.
Zum Befreien der Kisten von Etiketten wurden in der Vergangenheit insbesondere Lösungen gewählt, bei denen die Etiketten von den Trägerkisten durch Einsatz chemischer Lösungen oder/und durch thermische Bestrahlung abgelöst wurden. Diese Lösungen beruhen auf dem gemeinsamen Ansatz, den Klebstoff der in der Regel selbstklebenden Etiketten chemisch oder thermisch zu lösen und die Etiketten dann von den Trägerkisten abzustreifen oder abzuwaschen. Derartige Lösungen sind jedoch einerseits mit den heutigen Anforderungen an umweltfreundliche Verfahren nicht mehr zu vereinen und andererseits aus energetischen Gesichtspunkten ungünstig.To free the boxes of labels have been chosen in the past, in particular solutions in which the labels were detached from the carrier boxes by using chemical solutions and / or by thermal irradiation. These solutions are based on the common approach to chemically or thermally dissolve the adhesive of the usually self-adhesive labels and then strip or wash the labels of the carrier boxes. However, such solutions are on the one hand with the current requirements for environmentally friendly processes no longer unite and on the other hand unfavorable from an energetic point of view.
Ferner ist es aus einer im Internet verfügbaren Veröffentlichung bekannt (http://www.delbrouck.de/files/sealedcover folientechnik mit funktion 060222.pdf), einzelne Folien von Getränkekisten mittels einer entsprechend stark dimensionierten Saugvorrichtung einfach abzusaugen. Selbst bei stark dimensionierten Saugvorrichtungen, die entsprechend kostenintensiv und wegen ihres Stromverbrauchs teuer im Betrieb sind, kann es jedoch zu unbefrtedigenden Ablöseergebnissen kommen, wobei Etikettenreste oder ganze Etiketten an den Trägerkisten verbleiben und anschließend manuell entfernt werden müssen.Furthermore, it is known from a publication available on the Internet ( http://www.delbrouck.de/files/sealedcover folientechnik with function 060222.pdf), simply suck off individual slides of crates by means of a correspondingly large- sized suction device. However, even with highly dimensioned suction devices, which are correspondingly cost-intensive and expensive to operate because of their power consumption, there may be unsatisfactory release results, with label residues or entire labels remaining on the carrier boxes and then having to be removed manually.
Das Ablösen von Etiketten von Flaschen, die auf einem rotierenden Drehtisch geführt werden, ist aus dem Dokument
Schließlich zeigt das deutsche Gebrauchsmuster
Es ist eine Aufgabe der vorliegenden Erfindung, eine Etikettiervorrichtung der eingangs bezeichneten Art bereitzustellen, bei der die Qualität der Etikettierung auch bei Getränkekisten mit komplizierter Geometrie und kleinerer Oberflächenbereiche, an denen Etiketten angebracht werden können, mit hohem Durchsatz möglich ist.It is an object of the present invention to provide a labeling device of the type described in the introduction, wherein the quality of the labeling with high throughput is also possible in beverage crates with complicated geometry and smaller surface areas where labels can be attached.
Diese Aufgabe wird durch eine Etikettiervorrichtung der eingangs bezeichneten Art mit den Merkmalen des Anspruchs 1 gelöst. Insbesondere ist bei dieser Etikettiervorrichtung vorgesehen, dass die Andrückeinrichtung mit wenigstens zwei gegenläufig zueinander bewegbaren Druckkörpern ausgebildet ist, mit denen die Andrückeinrichtung an einem auf dem zu etikettierenden Gegenstand angebrachten Etikett angreift und dieses durch Auseinanderbewegen der Druckkörper auf dem zu etikettierenden Gegenstand streckt. Dabei können auch offene Bereiche, beispielsweise Fenster oder Durchbrüche, des zu etikettierenden Gegenstandes mit dem aufgebrachten Etikett überspannt werden.This object is achieved by a labeling device of the type described with the features of
Erfingdungsgemäß ist die Andrückeinrichtung mit den gegenläufig zueinander bewegbaren Druckkörpern versehen. Dadurch ist es möglich, ein auf einen zu etikettierenden Gegenstand, wie beispielsweise eine Getränkekiste, aufgebrachtes, jedoch wegen des noch nicht festhaftenden Klebstoffs oder Leims relativ zu dem zu etikettierenden Gegenstandverschiebbares Etikett mittels der Druckkörper in einer Sollposition auszurichten und zu strecken und gleichzeitig das Etikett an dem zu etikettierenden Gegenstand festzudrücken. Es wird also mit der vorliegenden Erfindung statt eines flächigen Andrückens infolge des Vorbeilaufens der Kiste an der Andrückeinheit gezielt mittels der Druckkörper das Etikett an dem zu etikettierenden Gegenstand positioniert und in der Sollposition angedrückt. Dadurch lässt sich die Etikettierung wesentlich exakter durchführen. Darüber hinaus lassen sich auch zu etikettierende Gegenstände zuverlässig mit Etiketten versehen, die nur eine relativ kleine Oberfläche aufweisen, an denen das Etikett anhaften soll, und ansonsten beispielsweise zur Materialeinsparung oder als Sichtfenster mit Durchbrüchen versehen sind. Letzteres ist insbesondere dann von Bedeutung, wenn transparente Etiketten verwendet werden. Die Etiketten werden dann an den verhältnismäßig kleinen zum Anbringen der Etiketten zur Verfügung stehenden Oberflächen des zu etikettierenden Gegenstands gezielt angebracht. Durch die erfindungsgemäße Streckbewegung der Druckkörper kann eine Verwerfung oder Blasenbildung an den Etiketten unterbunden werden, was das äußere Erscheinungsbild eines erfindungsgemäß etikettierten Gegenstands deutlich verbessert.According to the invention, the pressing device is provided with the pressure bodies movable in opposite directions. As a result, it is possible to align and stretch a label to be labeled on an object to be labeled, such as a crate, but because of the adhesive or glue not yet adhesive relative to the object to be labeled sliding label in a desired position and at the same time the label to press the object to be labeled. It is therefore with the present invention instead of a flat pressing due to the passage of the box on the Andrückeinheit targeted by means of the pressure body, the label positioned on the object to be labeled and pressed in the desired position. This makes the labeling much more accurate. In addition, articles to be labeled can be reliably provided with labels having only a relatively small surface to which the label is to adhere and otherwise are provided, for example, for material savings or as a viewing window with openings. The latter is particularly important when transparent labels are used. The labels are then selectively attached to the relatively small surfaces of the article to be labeled for applying the labels. As a result of the stretching movement of the pressure bodies according to the invention, a warpage or blistering on the labels can be prevented, which significantly improves the external appearance of an article labeled according to the invention.
Erfindungsgemäß ist ferner vorgesehen, dass die wenigstens zwei Druckkörper relativ zu einer Basis der Andrückeinrichtung gemeinsam verlagerbar sind. Dies bedeutet, dass die beiden Druckkörper zusätzlich zu ihrer gegenläufigen Bewegung auch noch eine überlagerte gemeinsame Bewegung relativ zu der Basis der Andrückeinrichtung vollziehen können. Dies wird gemäß der vorliegenden Erfindung dadurch erreicht, dass die wenigstens zwei Druckkörper an wenigstens einer Lagerschiene angebracht sind, die relativ zur Basis der Andrückeinrichtung oszillierend verlagerbar ist. Mit anderen Worten sind die Druckkörper nicht unmittelbar an der Basis gelagert, sondern an einem Zwischenelement, nämlich der Lagerschiene. Ferner ist in diesem Zusammenhang vorgesehen, dass die wenigstens eine Lagerschiene über eine erste Exzenterhebelanordnung an der Basis der Andrückeinrichtung angebracht und relativ zu dieser verlagerbar ist. Es versteht sich, dass auch mehrere Lagerschienen vorgesehen sein können, die miteinander verbunden oder separat über entsprechende Exzenterhebelanordnungen an der Basis gelagert werden können.According to the invention, it is further provided that the at least two pressure bodies are displaceable together relative to a base of the pressure device. This means that, in addition to their opposite movement, the two pressure bodies can also perform a superimposed joint movement relative to the base of the pressure device. This is achieved according to the present invention in that the at least two pressure bodies are mounted on at least one bearing rail, which is oscillatingly displaceable relative to the base of the pressure device. In other words, the pressure bodies are not mounted directly on the base, but on an intermediate element, namely the bearing rail. Furthermore, it is provided in this context that the at least one bearing rail is attached via a first eccentric lever arrangement to the base of the pressure device and is displaceable relative thereto. It is understood that a plurality of bearing rails can be provided, which can be connected to each other or stored separately via corresponding Exzenterhebelanordnungen to the base.
Es ist vorgesehen, dass die Bewegung der lagerschiene zu der Bewegung der zu etikettierenden Gegenstände, insbesondere Getränkekisten, auf der Fördereinrichtung synchronisiert ist. Dies bedeutet, dass die Lagerschiene sich zusammen mit den Druckkörpern synchronisiert zu der Förderbewegung der zu etikettierenden Gegenstände auf der Fördereinrichtung mitbewegt Daher ist es nicht erforderlich, die zu etikettierenden Gegenstände, insbesondere Getränkekisten, während des Andrückvorgangs anzuhalten. Demzufolge kann der Durchsatz hochgehalten werden.It is envisaged that the movement of the bearing rail to the movement of the objects to be labeled, in particular beverage crates, is synchronized on the conveyor. This means that the bearing rail moves along with the pressure bodies synchronized to the conveying movement of the objects to be labeled on the conveyor Thus, it is not necessary to stop the items to be labeled, especially beverage crates, during the Andrückvorgangs. As a result, the throughput can be kept high.
Die Synchronisation kann derart erfolgen, dass zwischen Lagerschiene und zu etikettierendem Gegenstand, der über die Fördereinrichtung gefördert wird, keine oder nur eine unwesentliche Relativbewegung in Förderrichtung stattfindet. Die die Druckkörper tragende Lagerschiene beschreibt also eine Bewegung, bei der sie der Bewegung der zu etikettierenden Gegenstände in Förderrichtung abschnittsweise folgt.The synchronization can take place in such a way that there is no or only an insignificant relative movement in the conveying direction between the bearing rail and the object to be labeled, which is conveyed via the conveying device. The bearing rail carrying the pressure bodies thus describes a movement in which it follows in sections the movement of the objects to be labeled in the conveying direction.
Ferner kann erfindungsgemäß vorgesehen sein, dass die Exzenterhebelanordnung zwischen Lagerschiene und Basis der Andrückeinrichtung ein erstes Paar paralleler oszillierend antreibbarer Exzenterhebel aufweist. Dabei kann vorgesehen sein, dass die erste Exzenterhebelanordnung motorisch, insbesondere mit einem Servomotor, antreibbar ist. Der Servomotor kann über eine Zahnradgetriebeanordnung, über ein Kettengetriebe oder über einen Zahnriemen mit der ersten Exzenterhebelanordnung kraftübertragend gekoppelt sein.Furthermore, it can be provided according to the invention that the eccentric lever arrangement has a first pair of parallel oscillating drivable eccentric levers between the bearing rail and the base of the pressing device. It can be provided that the first eccentric lever arrangement is motor-driven, in particular with a servomotor, can be driven. The servo motor can be coupled in a force-transmitting manner via a gear transmission arrangement, via a chain transmission or via a toothed belt to the first eccentric lever arrangement.
Um die vorstehend bereits erwähnte Streckbewegung der Druckkörper relativ zueinander zu realisieren, sieht eine Ausführungsvariante der Erfindung vor, dass jeder Druckkörper an der wenigstens einen Lagerschiene relativ zu dieser bewegbar gelagert ist. In diesem Zusammenhang kann vorgesehen sein, dass jeder Druckkörper jeweils mittels einer zweiten Exzenterhebelanordnung relativ zu der wenigstens einen Lagerschiene verlagerbar ist. So ist es bei einer Ausführungsvariante der Erfindung möglich, dass die zweite Exzenterhebelanordnung eine Parallelogramm-Hebelanordnung aufweist. Um die Streckbewegung zum Glattziehen und Andrücken des Etiketts zu erreichen, werden also die an der Lagerschiene gelagerten Druckkörper relativ voneinander weg bewegt, so dass sie das Etikett gleichmäßig auseinanderziehen, obgleich sich dieses zusammen mit dem zu etikettierenden Gegenstand, insbesondere der Getränkekiste, relativ zur Andrückvorrichtung bewegt. Gleichzeitig wird das Etikett an den zu etikettierenden Gegenstand angedrückt.In order to realize the above-mentioned stretching movement of the pressure bodies relative to one another, an embodiment variant of the invention provides that each pressure body is mounted on the at least one bearing rail so as to be movable relative thereto. In this context, it can be provided that each pressure body can be displaced in each case by means of a second eccentric lever arrangement relative to the at least one bearing rail. Thus, in one embodiment of the invention, it is possible for the second eccentric lever arrangement to have a parallelogram lever arrangement. In order to achieve the stretching movement for smooth drawing and pressing of the label, so stored on the bearing rail pressure body are relatively moved away from each other so that they spread the label evenly, although this together with the object to be labeled, especially the crate, relative to the pressing emotional. At the same time the label is pressed against the object to be labeled.
Erfindungsgemäß kann vorgesehen sein, dass einer der Hebel der Parallelogramm-Hebelanordnung über eine exzentrisch angetriebene Schubstange antreibbar ist. Die Schubstange kann separat von einer gesonderten Antriebsquelle angetrieben sein. Vorzugsweise ist aber vorgesehen, dass diese Schubstange wiederum exzentrisch über den vorstehend bereits erwähnten Servomotor angetrieben wird, der bereits zum Antreiben der ersten Exzenterhebelanordnung vorgesehen ist.According to the invention it can be provided that one of the levers of the parallelogram lever arrangement can be driven via an eccentrically driven push rod. The push rod may be driven separately from a separate drive source. Preferably, however, it is provided that this push rod is in turn driven eccentrically on the above-mentioned servo motor, which is already provided for driving the first eccentric lever assembly.
Bei einer bevorzugten Ausführungsvariante der Erfindung ist vorgesehen, dass die einem Paar aus Druckkörpern zugeordneten zweiten Exzenterhebelanordnungen derart zueinander gegenläufig antreibbar sind, dass sich die zugehörigen Druckkörper reziprozierend bis auf einen vorbestimmten Mindestabstand einander annähern und bis auf einen vorbestimmten Maximalabstand voneinander entfernen. Die Druckkörper bewegen sich dann, wenn sie sich in Anlage mit dem Etikett befinden, auseinander, und dann, wenn sie ohne Kontakt zu einem Etikett sind, wieder aufeinander zu. Dies wird dadurch erreicht, dass die vorstehend erwähnten ersten und zweiten Exzenterhebelanordnungen in ihrer Bewegung aufeinander abgestimmt sind. Diese Abstimmung erfolgt derart, dass die wenigstens eine Lagerschiene angetrieben durch die erste Exzenterhebelanordnung sich ausgehend von einer Ausgangsstellung entsprechend der Förderrichtung der Fördereinrichtung mit dem zu etikettierenden Gegenstand mitbewegt. Dabei greifen die Druckkörper an dem auszurichtenden und anzudrückenden Etikett an, strecken dieses und drücken es an dem zu etikettierenden Gegenstand an. Nach Abschluss des Streck- und Andrückvorgangs geben die Druckkörper das Etikett frei. In der Folge bewegt sich die wenigstens eine Lagerschiene aus der vorgerückten Stellung in die Ausgangsstellung zurück. Die Bewegung zwischen Ausgangsstellung und Entstellung kann reziprozierend erfolgen, oder durch eine geschlossene Bewegung entlang einer vorgegebenen Bewegungsbahn. In beiden Fällen werden die beiden Druckkörper wieder in ihre Ausgangsstellung zurückgeführt, in der sie minimalen Abstand haben und an der nächsten Getränkekiste ansetzen können.In a preferred embodiment of the invention, it is provided that the second eccentric lever arrangements assigned to a pair of pressure bodies can be driven in opposite directions in such a way that the associated pressure bodies reciprocally approach each other to a predetermined minimum distance and move away from each other to a predetermined maximum distance. The pressure bodies, when in contact with the label, move apart, and then face each other again when they are out of contact with a label. This is achieved in that the above-mentioned first and second eccentric lever assemblies are matched in their movement. These Tuning takes place in such a way that the at least one bearing rail, driven by the first eccentric lever arrangement, moves along with the object to be labeled starting from an initial position corresponding to the conveying direction of the conveying device. In this case, the pressure bodies engage the label to be aligned and pressed, stretch it and press it against the object to be labeled. Upon completion of the stretching and pressing operation, the pressure bodies release the label. As a result, the at least one bearing rail moves from the advanced position back to the starting position. The movement between starting position and dislocation may be reciprocating, or by a closed movement along a predetermined path of movement. In both cases, the two pressure bodies are returned to their original position, in which they have minimal distance and can start at the next crate.
Um die Etiketten an dem zu etikettierenden Gegenstand während des Andrückens und Streckens nicht zu beschädigen und andererseits zu garantieren, dass die Druckkörper hinreichend stark an den Etiketten angreifen können, um diese zu strecken, sieht eine Ausführungsvariante der Erfindung vor, dass jeder Druckkörper eine elastisch deformierbare Beschichtung mit hohem Reibwert, insbesondere ein Gummikissen oder ein Schwammelement, aufweist, womit der Druckkörper an dem Etikett angreift. So können die Druckkörper mit porösen Gummikissen, Gummischwämmen oder dergleichen ausgebildet sein. Ferner kann erfindungsgemäß vorgesehen sein, dass die Fördereinrichtung ein Förderband oder eine Förderkette aufweist. Beispielsweise bieten sich Scharnierbandketten an.In order not to damage the labels on the object to be labeled during pressing and stretching and on the other hand to guarantee that the pressure bodies can sufficiently attack the labels to stretch them, one embodiment of the invention provides that each pressure body is elastically deformable Coating with a high coefficient of friction, in particular a rubber pad or a sponge element has, with which the pressure body engages the label. Thus, the pressure bodies may be formed with porous rubber pads, rubber sponges or the like. Furthermore, it can be provided according to the invention that the conveyor has a conveyor belt or a conveyor chain. For example, offer hinge strap chains.
Eine Weiterbildung der Erfindung sieht vor, dass eine Positioniereinrichtung zum Positionieren der zu etikettierenden Gegenstände auf der Fördereinrichtung in vorbestimmten Sollabständen angebracht ist. Die Sollabstände sind derart zu wählen, dass sich die Andrückeinrichtung aus ihrer vorgerückten Endstellung nach dem Andrücken und Strecken der Etiketten an den zu etikettierenden Gegenständen wieder in ihre Ausgangsstellung zurückbewegen können, bevor sie an der nächsten Kiste angreifen.A development of the invention provides that a positioning device for positioning the articles to be labeled is mounted on the conveyor at predetermined desired distances. The desired distances are to be selected such that the pressing device can move back from its advanced end position after pressing and stretching the labels on the items to be labeled in their starting position before they attack the next box.
Im Detail kann vorgesehen sein, dass die Positioniereinrichtung wenigstens ein Greiferband, vorzugsweise zwei gegenüberliegende Greiferbänder, aufweist, mit dem/denen sie an einem zu etikettierenden Gegenstand angreift und diesen für eine Positionierung auf der Fördereinrichtung wechselweise festhält oder freigibt. Eine Weiterbildung der Erfindung sieht in diesem Zusammenhang vor, dass das wenigstens eine Greiferband mit Greiferlamellen aufweist, die aus einem Material mit hohem Reibwert hergestellt sind. Insbesondere ist erfindungsgemäß möglich, dass das wenigstens eine Greiferband zum Freigeben eines zu etikettierenden Gegenstands auf der Fördereinrichtung in Förderrichtung bewegbar ist.In detail, it can be provided that the positioning device has at least one rapier band, preferably two opposing rapier bands, with which it engages an object to be labeled and alternately holds or releases it for positioning on the conveyor. A development of the invention provides in this context, that has at least one gripper belt with gripper blades, which consists of a material with high Friction value are produced. In particular, it is possible according to the invention for the at least one gripper belt to be able to be moved on the conveyor in the conveying direction in order to release an article to be labeled.
Zur Erhöhung der Taktrate ist es selbstverständlich auch möglich, mehrere Andrückvorrichtungen hintereinander zu positionieren, die dann jeweils nur an jedem zweiten, dritten, etc. zu etikettierenden Gegenstand angreifen.To increase the clock rate, it is of course also possible to position a plurality of pressing devices in succession, which then act on only every second, third, etc., to be labeled object.
Ferner kann erfindungsgemäß vorgesehen sein, dass die Etikettenzuführeinrichtung ein Etikettenmagazin, eine Beleimungseinrichtung und eine Übergaberotor zum Aufbringen einzelner Etiketten auf die zu etikettierenden Gegenstände aufweist.Furthermore, it can be provided according to the invention that the label supply device has a label magazine, a gluing device and a transfer rotor for applying individual labels to the articles to be labeled.
Zur Ansteuerung der Andrückeinrichtung, insbesondere ihres Servomotors, kann erfindungsgemäß vorgesehen sein, dass eine Erfassungseinrichtung zum Erfassen einer augenblicklichen Position eines zu etikettierenden Gegenstands relativ zur Andrückeinrichtung nahe dieser angeordnet ist. So ist es möglich, beispielsweise dann, wenn kein zu etikettierender Gegenstand auf der Fördereinrichtung vorliegt, die Andrückeinrichtung passiv zu schalten. Ferner kann dann, wenn die zu etikettierenden Gegenstände nicht exakt in ihrer Sollposition auf der Fördereinrichtung liegen, eine jeweilige Ansteuerung der Andrückeinrichtung in Abhängigkeit von der aktuellen Position erfolgen.In order to control the pressing device, in particular its servo motor, it can be provided according to the invention that a detection device for detecting an instantaneous position of an object to be labeled relative to the pressing device is arranged close to it. Thus, it is possible, for example, when there is no object to be labeled on the conveyor, to switch the pressing device passively. Furthermore, if the objects to be labeled are not exactly in their desired position on the conveyor, then a respective control of the pressing device can be effected as a function of the current position.
Die Erfindung betrifft ferner ein Verfahren zum Etikettieren von Gegenständen, insbesondere von Getränkekisten, mit Etiketten, die mit einer Klebebeschichtung versehen sind, wobei das Verfahren die folgenden Schritte umfasst:
- Fördern der zu etikettierenden Gegenstände mit einer Fördereinrichtung,
- Bereitstellen und Anbringen von einzelnen mit einer Klebebeschichtung versehen Etiketten an den zu etikettierenden Gegenständen mit einer Etikettenzuführeinrichtung und
- Andrücken der an den zu etikettierenden Gegenständen angebrachten Etiketten mit einer Andrückeinrichtung.
- Conveying the articles to be labeled with a conveyor,
- Providing and applying individual adhesive coated labels to the articles to be labeled with a label feeder; and
- Pressing the attached to the items to be labeled labels with a pressing device.
Bei diesem Verfahren ist erfindungsgemäß vorgesehen, dass die an den zu etikettierenden Gegenständen angebrachten Etiketten während des Andrückens über die Andrückeinrichtung mittels wenigstens zweier sich gegenläufig bewegender Druckkörper gestreckt werden, und dass der Streckbewegung der sich gegenläufig bewegenden Druckkörper eine auf die Förderbewegung der Fördereinrichtung abgestimmte Folgebewegung überlagert wird. Schlieβlich kann erfindungsgemäß vorgesehen sein, dass die Druckkörper an wenigstens einer Lagerschiene angebracht sind, und derart bewegt werden, dass sie sich reziprozierend bis auf einen vorbestimmten Mindestabstand einander annähern und bis auf einen vorbestimmten Maximalabstand voneinander entfernen.In this method, the invention provides that the attached to the items to be labeled labels are stretched during pressing on the Andrückeinrichtung by means of at least two oppositely moving pressure body, and that the stretching movement of the counter-rotating Pressure body is superimposed on the conveying movement of the conveyor tuned subsequent movement. Finally, it can be provided according to the invention that the pressure bodies are mounted on at least one bearing rail, and are moved so that they approach each other reciprocally to a predetermined minimum distance and apart from each other to a predetermined maximum distance.
Wie eingangs bereits erläutert ist es bekannt, verschiedene Gegenstände mit Etiketten zu versehen, um diese hinsichtlich ihres Inhalts zu kennzeichnen. So werden Trägerkisten in der Lebensmittelindustrie, wie beispielsweise Getränkekisten, die aus wiederverwendbarem Kunststoff (z.B. PET) hergestellt sind, häufig etikettiert. Auf diese Art und Weise kann jeweils nach Befüllung der Kiste mit Flaschen eines bestimmten Produkts, beispielsweise einem Getränk einer bestimmten Sorte, die Kiste mit einem passenden Etikett versehen werden. Nach Entleerung und Rückgabe kann diese Kiste für ein neues Produkt, beispielsweise ein Getränk einer anderen Sorte, das allerdings in gleichartigen Einweg- oder Mehrweg-Flaschen abgefüllt ist, wieder verwendet werden. Das vorstehend beschriebene Verfahren und die vorstehend beschriebene Etikettiervorrichtung können auch dazu verwendet werden, derartige Mehrweg-Kisten erneut zu etikettieren. Hierfür müssen diese aber von den alten Etiketten befreit werden, die oftmals beschädigt sind.As already explained, it is known to provide various objects with labels in order to identify them in terms of their content. Thus, carrier boxes in the food industry such as beverage crates made from reusable plastic (e.g., PET) are often labeled. In this way, each time after filling the box with bottles of a particular product, such as a drink of a certain variety, the box will be provided with a suitable label. After emptying and return this box for a new product, for example, a drink of another variety, which is, however, filled in the same disposable or reusable bottles, reused. The method described above and the labeling device described above can also be used to re-label such reusable boxes. For this they must be freed from the old labels, which are often damaged.
Es ist daher Aufgabe eines weiteren Aspekts der vorliegenden Erfindung, eine Ablösevorrichtung und ein Verfahren zum Ablösen von Etiketten von Gegenständen, insbesondere von Trägerkisten, wie beispielsweise Trägerkisten für Getränke- oder Lebensmittelbehälter bereitzustellen, mit denen unter geringem technischem und energetischem Aufwand bei gleichzeitig hoher Umweltverträglichkeit ein zuverlässiges Ablösen einzelner Etiketten von Gegenständen, wie beispielsweise Getränke-Trägerkisten, gewährleistet istIt is therefore an object of a further aspect of the present invention to provide a detaching device and a method for detaching labels from articles, in particular carrier boxes, such as carrier boxes for beverage or food containers, with which at low technical and energy costs with high environmental impact Reliable detachment of individual labels of items, such as beverage carrier boxes guaranteed
Die erfindungsgemäße Etikettiervorrichtung kann eine Ablösevorrichtung aufweisen, die in einer Gesamtanlage der vorstehend beschriebenen Etikettiervorrichtung vorgeschaltet vorgesehen ist, wobei die Ablösevorrichtung umfasst: wenigstens einen in einer Drehrichtung drehantreibbaren Rotor mit wenigstens einem Unterdruckgreifer, wobei wenigstens ein mit einem abzulösenden. Etikett versehener Gegenstand im Bereich des sich drehenden Rotors positionierbar ist, wobei sich der Unterdruckgreifer an das abzulösenden Etikett anlegt und das abzulösende Etikett ansaugt und wobei das Etikett durch den von dem Unterdruckgreifer angelegten Unterdruck am Unterdruckgreifer gehalten und von dem Gegenstand ablösbar ist. Gemäß diesem Aspekt der Etikettiervorrichtung wird das abzulösende Etikett demnach unmittelbar von dem Unterdruckgreifer erfasst und über diesen angesaugt. Durch entsprechende Bewegung des Unterdruckgreifers von dem Gegenstand weg, was allein durch die Drehbewegung des Rotors oder/und durch eine radiale Bewegung des Unterdruckgreifers relativ zur Drehachse bewirkt werden kann, wird das Etikett sozusagen von dem Gegenstand sorgfältig abgerissen. Dadurch kann gewährleistet werden, dass das gesamte Etikett rückstandsfrei von dem Gegenstand entfernt wird.The labeling device according to the invention may comprise a detachment device, which is provided upstream in an overall system of the above-described labeling device, wherein the detachment device comprises at least one rotor rotatably driven in one direction of rotation with at least one vacuum gripper, at least one with one to be detached. Label provided item is positioned in the region of the rotating rotor, wherein the vacuum gripper bears against the label to be detached and sucks the label to be detached and wherein the label is held by the negative pressure applied by the negative pressure on the vacuum gripper and detachable from the object. According to this aspect of the labeling device, the label to be detached is accordingly detected directly by the vacuum gripper and sucked over it. By appropriate movement of the vacuum gripper away from the object, which can be effected solely by the rotational movement of the rotor and / or by a radial movement of the vacuum gripper relative to the axis of rotation, the label is so to speak, carefully demolished by the object. This can ensure that the entire label is removed without residue from the object.
Für die Entfernung des Etiketts sind weder chemische Lösungen noch eine thermische Behandlung des von dem Etikett zu befreienden Gegenstands noch eine leistungsstark dimensionierte Saugvorrichtung erforderlich, wie vorangehend im Hinblick auf den Stand der Technik beschrieben. Dadurch lassen die sich mit diesen Lösungen verbundenen Nachteile hinsichtlich des hohen Energieaufwands, der geringen Umweltverträglichkeit oder der verhältnismäßig hohen Versagensrate beim Ablösen von Etiketten vermeiden.For the removal of the label neither chemical solutions nor a thermal treatment of the article to be liberated from the label nor a powerfully sized suction device are required, as described above with respect to the prior art. As a result, the disadvantages associated with these solutions in terms of high energy consumption, low environmental impact or the relatively high failure rate when removing labels can be avoided.
Grundsätzlich ist es im Zusammenhang mit der Ablösevorrichtung möglich, an dem wenigstens einen Rotor lediglich einen Unterdruckgreifer vorzusehen. Um die Produktivität der Ablösevorrichtung weiter zu verbessern, kann eine Weiterbildung der Erfindung vorsehen, dass der Rotor eine Mehrzahl von im gleichen Winkelabstand zueinander angeordneten Unterdruckgreifern aufweist. So ist es möglich, einen oder mehrere Unterdruckgreifer in Form zweier Unterdruckgreifer-Baugruppen in einem Winkelabstand von 180° zueinander anzuordnen. Alternativ können auch beispielsweise drei Unterdruckgreifer-Baugruppen in einem Winkelabstand von 120° oder vier Unterdruckgreifer-Baugruppen in einem Winkelabstand von 90° vorgesehen sein. Je nach Anwendungsfall und Dimensionierung des von den Etiketten zu befreienden Gegenstands bietet sich die eine oder andere Alternative an.In principle, it is possible in connection with the detaching device to provide only one vacuum gripper on the at least one rotor. In order to further improve the productivity of the detachment device, a development of the invention can provide that the rotor has a plurality of vacuum grippers arranged at the same angular distance from one another. Thus, it is possible to arrange one or more vacuum grippers in the form of two vacuum gripper assemblies at an angular distance of 180 ° to each other. Alternatively, for example, three vacuum gripper assemblies can be provided at an angular distance of 120 ° or four vacuum gripper assemblies at an angular distance of 90 °. Depending on the application and dimensioning of the article to be liberated from the labels, one or the other alternative offers.
Ferner ist es möglich, eine Unterdruckgreifer-Baugruppe mit lediglich einem Unterdruckgreifer zu versehen. Um die Zuverlässigkeit der Ablösevorrichtung jedoch welter zu erhöhen, sieht eine Ausführungsvariante vor, dass in ein und derselben Winkelposition am Rotor eine Mehrzahl von Unterdruckgreifern in im wesentlichen vertikaler Richtung übereinander angeordnet sind. Mit anderen Worten kann bei dieser Ausführungsvariante eine Unterdruckgreifer-Baugruppe auch mit einer Mehrzahl von Unterdruckgreifern versehen sein, beispielsweise mit drei Unterdruckgreifern, die In vertikaler Richtung fluchtend zueinander, jedoch in gegenseitigem Abstand voneinander angeordnet sind.Furthermore, it is possible to provide a vacuum gripper assembly with only a vacuum gripper. However, in order to increase the reliability of the detaching device welter, an embodiment provides that in the same angular position on the rotor a plurality of vacuum grippers are arranged one above the other in a substantially vertical direction. In other words, in this embodiment, a vacuum gripper assembly can also be provided with a plurality of vacuum grippers, for example, with three vacuum grippers, which are arranged in the vertical direction in alignment with each other, but at a mutual distance from each other.
Grundsätzlich ist es möglich, allein durch die Drehbewegung des Rotors den wenigstens einen Unterdruckgreifer relativ zu dem von dem abzulösenden Etikett zu befreienden Gegenstand derart zu positionieren, dass das abzulösende Etikett zuverlässig von dem Unterdruckgreifer erfasst, angesaugt und von dem Gegenstand abgelöst wird. Es hat sich jedoch gezeigt, dass bei einer Weiterbildung die Zuverlässigkeit der Ablösevorrichtung dadurch verbessert werden kann, dass der wenigstens eine Unterdruckgreifer relativ zu einer Drehachse des Rotors in radialer Richtung verlagerbar ist.In principle, it is possible to position the at least one vacuum gripper relative to the object to be detached from the label alone by the rotational movement of the rotor in such a way that the label to be detached is reliably grasped, sucked and detached from the object by the vacuum gripper. However, it has been shown that in a further development, the reliability of the detaching device can be improved by the fact that the at least one vacuum gripper is displaceable relative to a rotational axis of the rotor in the radial direction.
So ist es gemäß einer Ausführungsvariante möglich, den Unterdruckgreifer in radialer Richtung auf den von dem Etikett zu befreienden Gegenstand durch eine Hubbewegung zu zu bewegen, um zu gewährleisten, dass der Unterdruckgreifer sicher an dem abzulösenden Etikett angreift. Ferner kann vorgesehen sein, dass der Unterdruckgreifer druckgesteuert derart in radialer Richtung verlagerbar ist, dass er sich dann von dem mit dem abzulösenden Etikett versehenen Gegenstand wegbewegt, sobald der Unterdruckgreifer das abzulösende Etikett hinreichend zum Ablösen angesaugt hat. Zusätzlich oder alternativ zu der oben genannten Hubbewegung ist es also möglich, durch eine Rückhubbewegung den Unterdruckgreifer in radialer Richtung von dem Gegenstand nach Ansaugen des Etiketts weg zu bewegen, um dadurch einen hinreichend starken, vorzugsweise abrupten "Abreißeffekt" zu erzielen. Dadurch kann die Wirksamkeit der Ablösevorrichtung hinsichtlich des Ablösen des Etiketts von dem Gegenstand weiter verbessert werden.Thus, according to one embodiment, it is possible to move the vacuum gripper in the radial direction towards the article to be liberated from the label by a lifting movement to ensure that the vacuum gripper securely engages the label to be detached. Furthermore, it can be provided that the vacuum gripper is pressure-controlled in such a way displaced in the radial direction, that he then moves away from the provided with the label to be detached item, as soon as the vacuum gripper has sucked the label to be detached sufficient for detachment. In addition or as an alternative to the above-mentioned lifting movement, it is thus possible to move the vacuum gripper in the radial direction away from the object after aspiration of the label by means of a return stroke, thereby achieving a sufficiently strong, preferably abrupt, "tear-off effect". Thereby, the effectiveness of the detachment device with regard to the detachment of the label from the article can be further improved.
Derartige Hubbewegungen oder Rückhubbewegungen können mechanisch, pneumatisch oder aber auch hydraulisch erreicht werden. Bei einer pneumatischen Steuerung der Hubbewegung beziehungsweise Rückhubbewegung ist es ferner möglich, diese in Abhängigkeit von dem gegenwärtigen Ansaugzustand zu steuern, beispielsweise derart, dass der Unterdruckgreifer in einer Hubbewegung auf den Gegenstand radial zu verlagert wird, solange das Etikett noch nicht hinreichend vom Unterdruckgreifer angesaugt ist, oder/und derart, dass der Unterdruckgreifer von dem Gegenstand abrupt weg bewegt wird, wenn erfasst wurde, dass das Etikett hinreichend stark von dem Unterdruckgreifer angesaugt wird. Eine derartige pneumatische Steuerung kann durch druckabhängig selbstschaltende pneumatische Bauelemente oder mittels aktiv ansteuerbarer Ventilelemente realisiert werden.Such strokes or Rückhubbewegungen can be achieved mechanically, pneumatically or hydraulically. In a pneumatic control of the lifting movement or return stroke movement, it is also possible to control these in dependence on the current intake state, for example, such that the vacuum gripper is displaced in a reciprocating motion on the object radially, as long as the label is not sufficiently sucked by the vacuum gripper , or / and such that the vacuum gripper is abruptly moved away from the object when it has been detected that the label is sufficiently sucked by the vacuum gripper. Such a pneumatic control can be realized by pressure-dependent self-switching pneumatic components or by means of actively controllable valve elements.
Alternativ zu einer aktiven Steuerung der Hubbewegung beziehungsweise Rückhubbewegung ist es gleichermaßen möglich, dass der Unterdruckgreifer relativ zu dem Rotor in radialer Richtung federnd gelagert ist, wobei sich der Unterdruckgreifer in radialer Richtung gegen die Federwirkung auf den Rotor zu verlagert, sobald er an dem abzulösenden Etikett angreift. Bei dieser Lösung wird der Unterdruckgreifer also dann, wenn er während seiner Rotationsbewegung mit dem Rotor an dem abzulösenden Etikett angreift, gegen die Federwirkung radial einwärts gedrückt. Dadurch kann eine hinreichend starke Anpresskraft des Unterdruckgreifers an dem Etikett erreicht und somit ein zuverlässiges Ansaugen des abzulösenden Etiketts durch den Unterdruckgreifer gewährleistet werden. Der Unterdruckgreifer kann bei dieser Ausführungsvariante beispielsweise durch den Unterdruck solange In seiner radial einwärts verlagerten Stellung gehalten werden, bis er das abgelöste Etikett wieder freigibt.As an alternative to an active control of the lifting movement or return stroke movement, it is equally possible that the vacuum gripper is resiliently mounted relative to the rotor in the radial direction, wherein the vacuum gripper moves in the radial direction against the spring action on the rotor as soon as it engages the label to be detached. In this solution, the vacuum gripper so when it engages during its rotational movement with the rotor on the label to be detached, pressed against the spring action radially inwardly. As a result, a sufficiently strong contact pressure of the negative pressure gripper can be achieved on the label and thus a reliable suction of the label to be detached by the vacuum gripper can be ensured. The vacuum gripper can be kept in its radially inwardly displaced position in this embodiment, for example, by the negative pressure until it releases the detached label again.
Um die Unterdruckquelle wirtschaftlich auslegen zu können, sieht eine Weiterbildung vor, dass in Abhängigkeit von der gegenwärtigen Winkelstellung des Rotors an den wenigstens einen Unterdruckgreifer Unterdruck anlegbar ist. Mit anderen Worten liegt nicht über die gesamte Rotationsbewegung eines oder mehrerer Unterdruckgreifer stets Unterdruck an diesen an. Vielmehr liegt der Unterdruck nur in den Bereich der Rotationsbewegung an, in dem es zu einem Kontakt, Ansaugen und Ablösen des Etiketts von dem Gegenstand kommt. Eine derartige winkelabhängige Unterdrucksteuerung kann beispielsweise mittels einer Unterdrucksteuerkurve erreicht werden. Zusätzlich oder alternativ kann die Unterdrucksteuerung auch mit gezielt ansteuerbaren Ventilen implementiert werden.In order to be able to design the vacuum source economically, a development provides that negative pressure can be applied as a function of the current angular position of the rotor to the at least one vacuum gripper. In other words, vacuum is not always applied to the entire rotational movement of one or more vacuum grippers. Rather, the negative pressure is only in the range of rotational movement, in which there is a contact, suction and detachment of the label from the object. Such angle-dependent negative pressure control can be achieved for example by means of a vacuum control curve. Additionally or alternatively, the negative pressure control can also be implemented with selectively controllable valves.
Eine Weiterbildung sieht vor, dass die Ablösevorrichtung mit einer Fördereinrichtung, insbesondere einem Förderband oder einer Förderkette, versehen ist, mittels der eine Mehrzahl der mit abzulösenden Etiketten versehenen Gegenständen relativ zu dem wenigstens einen drehbaren Rotor positionierbar ist, wobei der wenigstens eine Rotor relativ zu der Fördereinrichtung ortsfest angeordnet ist. In diesem Zusammenhang kann vorgesehen sein, dass die Fördereinrichtung den wenigstens einen mit einem abzulösenden Etikett versehenen Gegenstand mit einer Fördergeschwindigkeit relativ zu dem wenigstens einen Rotor fördert, wobei die Drehbewegung, insbesondere die Drehgeschwindigkeit, des wenigstens einen Rotors relativ zu der Fördergeschwindigkeit der Fördereinrichtung synchronisiert ist. Dabei kann bei einer Ausführungsvariante vorgesehen sein, dass die Fördergeschwindigkeit der Fördereinrichtung und die Drehbewegung des Rotors zueinander derart synchronisiert sind, dass immer dann, wenn wenigstens ein Unterdruckgreifer in eine der Fördereinrichtung nahe Stellung gelangt, ein mit einem abzulösenden Etikett versehener Gegenstand von der Fördereinrichtung in einerA further development provides that the detachment device is provided with a conveying device, in particular a conveyor belt or a conveyor chain, by means of which a plurality of the objects to be detached with labels can be positioned relative to the at least one rotatable rotor, wherein the at least one rotor relative to the Conveyor is arranged stationary. In this context, it can be provided that the conveying device conveys the at least one object provided with a label to a conveying speed relative to the at least one rotor, the rotational movement, in particular the rotational speed, of the at least one rotor being synchronized relative to the conveying speed of the conveying device , It can be provided in one embodiment, that the conveying speed of the conveyor and the rotational movement of the rotor are synchronized to each other such that whenever at least one vacuum gripper in one of the conveyor comes close position, provided with a detachable label object from the conveyor in one
Ablösestellung relativ zu dem Unterdruckgreifer positioniert ist.Ablösestellung is positioned relative to the vacuum gripper.
Vorangehend wurde insbesondere auf den Ablösevorgang eines abzulösenden Etiketts von dem Gegenstand, beispielsweise der Getränkekiste, eingegangen. Nachdem das Etikett von dem Gegenstand, beispielsweise der Getränkekiste, abgelöst wurde, befindet sich dieses Etikett aber noch an dem wenigstens einen Unterdruckgreifer. Um das Etikett nun von dem Unterdruckgreifer zu trennen, ist dem wenigstens einen drehbaren Rotor eine Abstreifereinrichtung zum Abstreifen eines abgelösten Etiketts von dem wenigstens einen Unterdruckgreifer zugeordnet. In diesem Zusammenhang kann vorgesehen sein, dass die Abstreifereinrihtung wenigstens zwei im Abstand zueinander angeordnete Abstreiferholme aufweist, zwischen denen der wenigstens eine Unterdruckgreifer bei seiner Drehbewegung mit dem Rotor hindurch läuft. Um das Lösen des Etiketts von dem wenigstens einen Unterdruckgreifer im Bereich der Abstreifereinrichtung zu unterstützen, sieht eine Weiterbildung der Erfindung vor, dass im Bereich der Abstreifereinrichtung der Unterdruck abgebaut wird. Dadurch werden die Kräfte zum Ablösen des Etiketts von dem wenigstens einen Unterdruckgreifer erheblich reduziert.Previously, particular attention was paid to the detachment process of a label to be detached from the object, for example the crate. After the label has been detached from the object, for example the crate, this label is still on the at least one vacuum gripper. In order to separate the label now from the vacuum gripper, the at least one rotatable rotor is associated with a stripping device for stripping a detached label from the at least one vacuum gripper. In this context, it can be provided that the Abstreifereinrihtung has at least two spaced apart Abstreiferholme, between which the at least one vacuum gripper passes during its rotational movement with the rotor. In order to assist the detachment of the label from the at least one vacuum gripper in the region of the wiper device, a development of the invention provides that the negative pressure is reduced in the region of the wiper device. As a result, the forces for detaching the label from the at least one vacuum gripper are significantly reduced.
Häufig sind etikettierte Gegenstände, wie beispielsweise Getränkekisten, auf zwei voneinander abgewandten Seiten mit Etiketten versehen. Um zu ermöglichen, dass derartige Gegenstände mit wenigen Schritten von den abzulösenden Etiketten befreit werden, sind wenigstens zwei gegenläufig drehbare Rotoren mit Unterdruckgreifern beidseits des Gegenstands angeordnet, um Etiketten von den entgegengesetzten Seiten des Gegenstands abzulösen. Mit dieser Weiterbildung ist es möglich, gleichzeitig an verschiedenen Seiten des Gegenstands, beispielsweise der Getränkekiste, Etiketten anzulösen.Often tagged items, such as crates, are provided on two opposite sides with labels. In order to allow such articles to be released from the peelable labels in a few steps, at least two counterrotatable rotors with vacuum grippers are disposed on both sides of the article to detach labels from the opposite sides of the article. With this development, it is possible to solve at the same time on different sides of the article, such as the crate, labels.

Das Etikett liegt nach dem Etikettlervorgang glatt und faltenfrei an der Kistenoberfläche an, so dass ein Etikettiervorgang unter hoher Qualität erreicht wird. Der Fluss der Getränkekisten muss nicht unterbrochen werden, weil sich die Andrückeinheiten mit den in Förderrichtung R laufenden Kisten mitbewegen.With the invention it is possible, wrinkle-free and individual labels attach to the box surface, even if it is provided with openings or windows or other cavities. The label is smooth and wrinkle-free on the box surface after the labeler operation, so that high-quality labeling is achieved. The flow of beverage crates does not have to be interrupted because the pressing units move with the crates running in the conveying direction R.

Die Ablösevorrichtung 210 umfasst eine auf einem Maschinengestell aufgebaute Fördereinrichtung 212, die mit einem Förderband 214 versehen ist. Das Förderband 214 kann eine Fortsetzung des Förderbands 12 der Etikettiervorrichtung gemäß

Die Offenbarung betrifft demnach auch eine Ablösevorrichtung und ein Verfahren zum Ablösen von Etiketten von Gegenständen, insbesondere Trägerkisten, wie beispielweise Getränkekisten oder Lebensmittelbehälter, wobei die Etiketten auf die Kisten mit einem Klebstoff aufgeklebt oder anderweitig an den Kisten adhäsiv angebracht sind und wobei nach Gebrauch der Kisten der Ablösevorgang allein mittels eines Rotors und mit diesem mitrotierenden Unterdruckgreifern erfolgt. Der Rotor dreht sich dabei im Wesentlichen kontinuierlich um seine Drehachse in einer vorgegebenen Drehrichtung, das heißt die Drehrichtung ändert sich nicht. Die Drehgeschwindigkeit des Rotors kann jedoch in Abstimmung auf die Bewegung des Förderbands, insbesondere in Abstimmung auf die Geschwindigkeit dieser Bewegung synchronisiert werden. Dadurch ist gewährleistet, dass immer dann ein Unterdruckgreifer in den Bereich des Förderbands gelangt, wenn sich auch eine von einem Etikett zu befrelende Trägerkiste in diesem Bereich befindet. Dadurch kann gewährleistet werden, dass ein Unterdruckgreifer immer zuverlässig an ein Etikett angelegt wird, sich an diesem festsaugt und es von dem Gegenstand ablöst. Um eine entsprechende Steuerung zu realisieren, können beispielsweise optische Sensoren vorgesehen werden, die die aktuelle Position der auf dem Förderband laufenden Trägerkisten erfassen.The disclosure accordingly also relates to a detaching device and a method for detaching labels from articles, in particular carrier boxes, such as crates or food containers, the labels being applied to the boxes glued with an adhesive or otherwise adhesively attached to the boxes and wherein after use of the boxes, the detachment process takes place solely by means of a rotor and with this co-rotating vacuum grippers. The rotor rotates substantially continuously about its axis of rotation in a predetermined direction of rotation, that is, the direction of rotation does not change. However, the rotational speed of the rotor may be synchronized in accordance with the movement of the conveyor belt, in particular in accordance with the speed of this movement. This ensures that a vacuum gripper always reaches the area of the conveyor belt when a carrier box to be embossed by a label is also located in this area. This can ensure that a vacuum gripper is always reliably applied to a label, sucks on this and peels it from the object. In order to realize a corresponding control, for example optical sensors can be provided which detect the current position of the carrier boxes running on the conveyor belt.
Mit der beschriebenen Lösung lassen sich auch aufwendige Ablösevorrichtung und Verfahren ersetzen, die beispielsweise ein Lösen mit aggressiven chemischen Lösungsmitteln und/oder ein energetisch aufwendiges thermisches Ablösen vorsehen. Die Lösung ist einfach aufgebaut und besitzt eine äußerst zuverlässige Funktionsweise mit geringer Verschleißanfälligkeit.With the solution described can also replace expensive detachment device and methods that provide, for example, a release with aggressive chemical solvents and / or an energetically complex thermal detachment. The solution is simple and has a very reliable operation with low susceptibility to wear.
Es sei nochmals darauf hingewiesen, dass die Ablösevorrichtung im Rahmen einer größeren Anlage zur Verarbeitung von wiederverwendbaren Getränkekisten der erfindungsgemäßen Etikettiervorrichtung vorgeschaltet sein kann, um bereits benutzte Getränkekisten zunächst von alten, abzulösenden Etiketten zu befreien, die Getränkekiste dann gegebenenfalls noch zusätzlich zu reinigen, und anschließend mit neuen Etiketten zu versehen.It should again be noted that the removal device may be upstream in the context of a larger system for processing reusable crates of the labeling invention to previously used crates first rid of old labels to be detached, then possibly additionally clean the crate, and then to be provided with new labels.
