Abstract

A labelling device for applying a label to an article (27, 28), particularly a large label to a paper roll, is disclosed which has a label-receiving device (10) and a pressing roller (13), which are arranged on a common support (8). In known devices of this type, the paper roll must be rotated in order to be provided with the label. It is here not ensured that the label adheres at the correct point and completely. By way of the novel device, it is achieved that the label adheres reliably to the desired position and completely. To this end, the support (8) can move in a horizontal direction and in a vertical direction, the two movements being independent of each other, and the label-receiving device (10) and/or the pressing roller (13) can move on the support relative to each other. Furthermore, a method is disclosed for applying the label to the surface of an article, in particular a paper roll, in which the label is taken from a receiving station, a layer of adhesive is generated, the label is transported to the article and is there pressed onto the article by means of a pressing roller. The pressing roller is here moved, under pressure, over the surface of the stationary article. <IMAGE>

Description

Die Erfindung betrifft eine Vorrichtung zum Aufbringen eines Etiketts auf einen Gegenstand mit einer Etikettenaufnahmeeinrichtung und einer Andruckrolle, die an einem gemeinsamen in horizontaler und in vertikaler Richtung bewegbaren Träger angeordnet sind, und ein Verfahren zum Aufbringen eines Etiketts auf die Oberfläche eines Gegenstandes, bei dem das Etikett zum Gegenstand transportiert und dort mittels einer Andruckrolle, die unter Druck über die Oberfläche des stillstehenden Gegenstandes bewegt wird, an den Gegenstand angedrückt wird.The invention relates to a device for applying a label to an object with a label receiving device and a pressure roller, which are arranged on a common carrier which can be moved in the horizontal and vertical directions, and a method for applying a label to the surface of an object, in which the The label is transported to the object and is pressed against the object there by means of a pressure roller which is moved under pressure over the surface of the stationary object.

Eine solche Vorrichtung und ein solches Verfahren sind aus FR-A-1 494 894 bekannt. Die Etikettierungsvorrichtung weist eine Etikettenaufnahmeeinrichtung und eine Andruckrolle auf, die an einem gemeinsamen in horizontaler und vertikaler Richtung bewegbaren Träger angeordnet sind. Die bekannte Vorrichtung bringt die Etiketten dadurch auf einen Gegenstand auf, daß sie mit der dem Gegenstand zugewandten Spitze der Etikettenaufnahmeeinrichtung ein Rechteck beschreibt, an dessen einer vertikaler Bewegungsbahn das Etikett an den Gegenstand zur Anlage gebracht wird. Die nachfolgende Andruckrolle fährt dabei über das Etikett. Andruckrolle und Etikettenaufnahmeeinrichtung führen die gleichen Bewegungen aus, weil sie starr am Träger befestigt sind und ihre Bewegungen durch die Bewegung des Trägers verursacht werden, der mit Hilfe einer Nockenscheibe gesteuert wird.Such a device and such a method are known from FR-A-1 494 894. The labeling device has a label receiving device and a pressure roller which are arranged on a common carrier which can be moved in the horizontal and vertical directions. The known device applies the labels to an object in that it describes a rectangle with the tip of the label receiving device facing the object, on the rectangle the label is brought into contact with the object in a vertical movement path. The following pressure roller runs over the label. The pinch roller and label take-up device perform the same movements because they are rigidly attached to the carrier and their movements are caused by the movement of the carrier, which is controlled by means of a cam disk.

Eine weitere Vorrichtung mit einer Etikettenaufnahmeeinrichtung und einer Andruckrolle, die an einem gemeinsamen Träger angeordnet sind, ist aus DE-A-37 40 093 und FR-A-2 607 471 bekannt. Bei dieser Vorrichtung ist eine Etikettenaufnahmeeinrichtung zusammen mit einer Andruckrolle an einem abgewinkelten Hebel gelagert. Ein Etikett wird auf die Etikettenaufnahmeeinrichtung geschoben und dort mittels Unterdruck festgehalten. Der gesamte Hebel wird um eine feste horizontale Achse geschwenkt, bis die Etikettenaufnahmeeinrichtung an der zu etikettierenden Papierrolle anliegt. Die Papierrolle wird dann gedreht, wodurch das Etikett von der Etikettenaufnahmeeinrichtung herabgezogen und durch die Andruckrolle an der Papierrolle festgedrückt wird.Another device with a label receiving device and a pressure roller, which are arranged on a common carrier, is known from DE-A-37 40 093 and FR-A-2 607 471. In this device, a label receiving device is mounted together with a pressure roller on an angled lever. A label is pushed onto the label receiving device and held there by means of negative pressure. The entire lever is pivoted about a fixed horizontal axis until the label receiving device lies against the paper roll to be labeled. The paper roll is then rotated, whereby the label is pulled down from the label holder and pressed against the paper roll by the pressure roller.

Der Nachteil dieser Vorrichtung liegt darin, daß die zu etikettierende Packung relativ zur Etikettenaufnahmeeinrichtung bewegt werden muß, um das Etikett aufzubringen. Dazu ist eine in der Regel runde Packung, d.h. eine Rolle, notwendig, die um ihre Achse gedreht wird. Es können zwar auch ebene Flächen, z.B. die Stirnflächen einer Packung beklebt werden. Dazu ist jedoch ein Umbau der Vorrichtung notwendig, so daß die Drehachse des Hebels nicht mehr horizontal, sondern vertikal liegt. Der zu etikettierende Gegenstand muß dann linear an der Etikettenaufnahmeeinrichtung vorbeigezogen werden. Insbesondere bei schweren Gegenständen, die verpackt und etikettiert werden sollen, ist ein großer Antrieb erforderlich, um die notwendige Bewegung des Gegenstandes sicherzustellen. Da schwere Gegenstände nur relativ schwer zu bremsen sind, ist es schwierig, das Etikett präzise an einer gewünschten Stelle zu plazieren. Wenn das Etikett beim Aufschieben auf die Etikettenaufnahmeeinrichtung nicht ganz präzise plaziert worden ist, ist es möglich, daß es bereits über die Andruckrolle übersteht. Beim Drehen der Packung wird dann nicht mehr das gesamte Etikett durch die Andruckrolle an der Packung festgelegt, so daß eine vollständige Befestigung des Etiketts nicht gewährleistet ist.The disadvantage of this device is that the package to be labeled has to be moved relative to the label receiving device in order to apply the label. This usually requires a round pack, ie a roll, which is rotated around its axis. Even flat surfaces, for example the end faces of a pack, can be stuck on. However, this requires a modification of the device so that the axis of rotation of the lever is no longer horizontal, but vertical. The object to be labeled must then be drawn linearly past the label receiving device. Especially when it comes to heavy items that need to be packaged and labeled, it's a big one Drive required to ensure the necessary movement of the object. Because heavy objects are relatively difficult to brake, it is difficult to place the label precisely at a desired location. If the label was not placed very precisely when it was pushed onto the label receiving device, it is possible that it already protrudes over the pressure roller. When the package is rotated, the entire label is then no longer fixed to the package by the pressure roller, so that a complete attachment of the label is not guaranteed.

FR-A-1 487 135 beschreibt eine weitere Etikettierungsvorrichtung mit einer Trägerbahn, auf der eine Vielzahl von Etiketten mit ihrer Bildseite der Trägerbahn zugewandt und der Reihe nach aufgebracht sind. Die Trägerbahn wird nun über einen Andruckrollenmechanismus so an einen Gegenstand zur Anlage gebracht, daß ein Etikett mit seiner Befestigungsseite am Gegenstand anliegt. Alsdann wird eine Andruckrolle über die Trägerbahn hinund hergeführt.FR-A-1 487 135 describes a further labeling device with a carrier web, on which a plurality of labels face the carrier web with their image side and are applied in sequence. The carrier web is now brought into contact with an object via a pressure roller mechanism in such a way that a label lies with its fastening side on the object. Then a pressure roller is guided back and forth over the carrier web.

Es ist die Aufgabe der vorliegenden Erfindung, eine Vorrichtung und ein Verfahren anzugeben, mit denen ein Etikett sicher vollständig anliegend auf jeder Seite eines Gegenstandes befestigt werden kann.It is the object of the present invention to provide an apparatus and a method with which a label can be securely attached completely on each side of an object.

Diese Aufgabe wird bei einer Etikettierungsvorrichtung der eingangs genannten Art dadurch gelöst, daß die Etikettenaufnahmeeinrichtung und die Andruckrolle, die durch jeweils ihnen zugeordnete getrennte Antriebe in entsprechende Arbeitspositionen verbringbar sind, verlagerbar an dem Träger gehaltert sind.This object is achieved in a labeling device of the type mentioned at the outset in that the label receiving device and the pressure roller, which can be moved into corresponding working positions by respective associated separate drives, are displaceably mounted on the carrier.

Mit dieser Vorrichtung lassen sich sowohl Stirnetiketten, d.h. Etiketten, die auf die Stirnseite einer Papierrolle geklebt werden, als auch Ballenetiketten, d.h. Etiketten, die auf die Umfangsfläche einer Papierrolle geklebt werden, verarbeiten, ohne den Aufbau der Vorrichtung zu ändern. Damit ergibt sich eine größere Vielfalt von zu etikettierenden Gegenständen. Auch die Größe der zu etikettierenden Gegenstände kann stark variieren. Eine Begrenzung ist praktisch nur durch die Bauhöhe und die Baulänge der Vorrichtung gegeben. Das Gewicht des zu etikettierenden Gegenstandes spielt keine Rolle mehr. Der Gegenstand muß nicht mehr bewegt, also nicht mehr beschleunigt und nicht mehr abgebremst werden. Dadurch kann das Etikett sehr präzise plaziert werden. Das Aufbringen und das Andrücken des Etiketts sind entkoppelt. Es ist sogar möglich, ein bereits vorgeklebtes Etikett mit der erfindungsgemäßen Vorrichtung erneut anzudrücken, ohne daß die Etikettenaufnahmeeinrichtung tätig werden muß. Durch die horizontale Bewegungsmöglichkeit der Etikettenaufnahmestation können Etiketten von mehreren Etikettenaufnahmepositionen aufgenommen werden. Dies erleichtert die Etikettierung verschiedenartiger Gegenstände mit unterschiedlichen Etiketten, ohne daß ein großer Vorbereitungsaufwand notwendig ist. Mit Vorteil lassen sich mit der erfindungsgemäßen Vorrichtung Großetiketten verarbeitetn, d.h. solche Etiketten, die nicht vollständig auf der Vorderseite eines Stempels ausgerichtet und dann mit dem Stempel auf die zu etikettierende Oberfläche gebracht werden. Neben Papierrollen lassen sich auch andere große Gegenstände etikettieren.With this device, both end labels, i.e. Labels that are glued to the face of a roll of paper, as well as bale labels, i.e. Process labels that are stuck to the peripheral surface of a roll of paper without changing the structure of the device. This results in a greater variety of objects to be labeled. The size of the items to be labeled can also vary widely. A limitation is practically only given by the height and length of the device. The weight of the item to be labeled no longer matters. The object no longer has to be moved, that is to say it no longer needs to be accelerated and decelerated. This allows the label to be placed very precisely. The application and the pressing of the label are decoupled. It is even possible to press an already pre-glued label again with the device according to the invention without the label receiving device having to operate. Due to the horizontal movement possibility of the label pick-up station, labels can be picked up from several label pick-up positions. This facilitates the labeling of different types of objects with different labels without the need for a large amount of preparation. Large labels can advantageously be processed with the device according to the invention, i.e. those labels that are not completely aligned on the front of a stamp and then brought with the stamp onto the surface to be labeled. In addition to paper rolls, other large objects can also be labeled.

In einer vorteilhaften Ausführungsform ist die Etikettenaufnahmeeinrichtung um eine Schwenkachse, die parallel zur Andruckrollenachse liegt, gegenüber dem Träger verschwenkbar. Die Lage, in der das Etikett von seiner Aufnahmeposition aufgenommen wird, und die Klebelage, d.h. die Lage, in der das Etikett am zu etikettierenden Gegenstand angebracht wird, müssen nicht mehr gleich sein. Beispielsweise ist es möglich, ein horizontal liegendes Etikett von der Aufnahmeposition aufzunehmen und an eine vertikale Fläche zu kleben. Die Aufnahmevorrichtung kann vorteilhafterweise weggeschwenkt werden, um beim Andrücken nicht zu stören.In an advantageous embodiment, the label receiving device can be pivoted relative to the carrier about a pivot axis which is parallel to the pinch roller axis. The position in which the label is picked up from its receiving position and the adhesive layer, ie the position in which the label is attached to the object to be labeled, no longer have to be the same be. For example, it is possible to pick up a horizontal label from the recording position and stick it to a vertical surface. The receiving device can advantageously be pivoted away so as not to interfere with the pressing.

In einer weiteren bevorzugten Ausführungsform ist die Andruckrolle um eine Schwenkachse, die parallel zur Andruckrollenachse liegt, gegenüber dem Träger verschwenkbar. Unabhängig von der Etikettenaufnahmeeinrichtung kann also die Andruckrolle geschwenkt werden, so daß sie beim Aufnehmen, beim Transport und beim Ankleben des Etiketts an den Gegenstand durch die Etikettenaufnahmeeinrichtung nicht stört.In a further preferred embodiment, the pressure roller can be pivoted relative to the carrier about a pivot axis which is parallel to the pressure roller axis. Independently of the label receiving device, the pressure roller can thus be swiveled so that it does not interfere with the label receiving device when picking up, transporting and sticking the label onto the object.

Mit Vorteil ist ein Andruckrollenschwenkantrieb vorgesehen, der die Andruckrolle über ein Hebelgestänge um ihre Schwenkachse verschwenkt. Der Antrieb stellt also sicher, daß zusätzlich zu der horizontalen und der vertikalen Bewegung des gemeinsamen Trägers eine davon unabhängige Schwenkbewegung der Andruckrolle sichergestellt ist. Damit kann die Andruckrolle in jeder Position des Trägers gegen den Gegenstand geschwenkt werden. Durch Verfahren des Trägers in horizontale und/oder vertikale Richtung wird dann das Etikett am Gegenstand festgedrückt bzw. festgewalzt.A pinch roller swivel drive is advantageously provided which pivots the pinch roller about its pivot axis via a lever linkage. The drive thus ensures that, in addition to the horizontal and vertical movement of the common carrier, an independent pivoting movement of the pressure roller is ensured. The pressure roller can thus be pivoted against the object in any position of the carrier. The label is then pressed or rolled onto the object by moving the carrier in the horizontal and / or vertical direction.

Dabei ist es von Vorteil, daß der Andrucksrollenschwenkantrieb die Andruckrolle unter einem permanenten Druck gegen den Gegenstand preßt. Damit folgt die Andruckrolle der Kontur eines Gegenstandes, auch wenn die zu etikettierende Oberfläche nicht in einer Ebene liegt. Insbesondere können damit die Mantelflächen von Zylindern etikettiert werden.It is advantageous that the pinch roller swivel drive presses the pinch roller under permanent pressure against the object. The pressure roller thus follows the contour of an object, even if the surface to be labeled is not in one plane. In particular, the lateral surfaces of cylinders can be labeled with it.

Vorteilhafterweise ist die Andruckrolle um einen Winkel im Bereich zwischen 120° und 180° schwenkbar. Damit ist sichergestellt, daß die Etikettenaufnahmeeinrichtung ungestört arbeiten kann und nicht durch die Andruckrolle behindert wird. Erst wenn die Etikettenaufnahmeeinrichtung das Etikett an die Position vor die oder an der zu beklebenden Oberfläche gebracht hat, wird die Andruckrolle um den vorbestimmten Winkel geschwenkt, um ihrerseits tätig zu werden.The pressure roller can advantageously be pivoted through an angle in the range between 120 ° and 180 °. This ensures that the label receiving device can work undisturbed and is not hindered by the pressure roller. Only when the label receiving device has brought the label into position in front of or on the surface to be glued is the pressure roller pivoted through the predetermined angle in order to act on its part.

Bevorzugterweise weist das Hebelgestänge zwei Lagerhebel, die an einem Ende die Andruckrolle in selbsteinstellenden Pendellagen tragen und am anderen Ende in der Schwenkachse gelagert sind, und einen Antriebshebel auf, der kürzer als die Lagerhebel ist, der an einem Ende mit der Schwenkachse verbunden ist, wobei die Schwenkachse mittels Drehfedern mit den Lagerhebeln verbunden ist, und mit diesem einen spitzen Winkel einschließt und der am anderen Ende mit dem Andruckrollenschwenkantrieb verbunden ist. Dadurch ist ein Übersetzungsverhältnis zwischen dem Weg, den der Andruckrollenschwenkantrieb zurücklegt, und dem Weg, den die Andruckrolle selbst zurücklegt, gegeben, d.h. der Antriebsweg oder -hub des Antriebs kann kürzer sein als der Andruckrollenweg. Der Andruckrollenschwenkantrieb kann daher kleiner dimensioniert werden. Zwischen Antriebshebel und Bewegungsrichtung des Andruckrollenschwenkantriebs ist immer ein Winkel vorhanden, so daß bei jeder Bewegung des Andruckrollenschwenkantriebs ein Moment auf den Antriebshebel ausgeübt wird und sichergestellt ist, daß die Andruckrolle verschwenkt wird.Preferably, the lever linkage has two bearing levers which support the pressure roller in self-adjusting pendulum positions at one end and are mounted in the pivot axis at the other end, and a drive lever which is shorter than the bearing lever and which is connected at one end to the pivot axis, wherein the pivot axis is connected to the bearing levers by means of torsion springs, and encloses an acute angle with the latter and is connected at the other end to the pinch roller pivot drive. This provides a gear ratio between the path that the pinch roller swivel drive travels and the path that the pinch roller itself travels, i.e. the drive path or stroke of the drive can be shorter than the pressure roller path. The pinch roller swivel drive can therefore be dimensioned smaller. There is always an angle between the drive lever and the direction of movement of the pinch roller swivel drive, so that with each movement of the pinch roller swivel drive a moment is exerted on the drive lever and it is ensured that the pinch roller is pivoted.

In einer weiteren bevorzugten Ausführungsform ist die Etikettenaufnahmeeinrichtung an einer unterhalb ihrer Bewegungsbahn angeordneten Klebervermittlungsstation vorbeiführbar. Die Klebervermittlungsstation kann dabei eine einfache Wassersprühdüse sein, wenn gummierte Etiketten verwendet werden, sie kann jedoch auch eine Leimauftragungsstation sein, an der mit Hilfe einer Sprühdüse, einer Leimwalze oder einer Bürste Leim auf die Klebeseite des Etiketts aufgetragen wird, wenn nichtgummierte Etiketten verwendet werden.In a further preferred embodiment, the label receiving device can be guided past an adhesive transfer station arranged below its path of movement. The adhesive transfer station can be a simple water spray nozzle if rubberized labels used, but it can also be a glue application station, at which glue is applied to the adhesive side of the label with the aid of a spray nozzle, a glue roller or a brush, if non-rubberized labels are used.

Bei einem Verfahren der eingangs genannten Art wird die oben genannte Aufgabe dadurch gelöst, daß das Etikett aus einer Aufnahmeposition durch eine translatorische Bewegung in eine Abgabeposition verbracht wird, bei der das Etikett auf dem Gegenstand angeheftet wird, und daß anschließend eine vollständige Verklebung über eine auf der Etikettenfläche in zwei entgegengesetzte Richtungen verlagerbare Andruckvorrichtung erfolgt.In a method of the type mentioned, the above-mentioned object is achieved in that the label is moved from a receiving position by a translational movement into a delivery position, in which the label is attached to the object, and that a complete adhesive application is then carried out the label surface takes place in two opposite directions movable pressure device.

Es ist also nur ein kleiner Antrieb erforderlich, der die Andruckrolle gegenüber dem Gegenstand bewegt. Auch bei schweren Gegenständen, die eine hohe Trägheitsmasse haben, ist kein größerer Antrieb notwendig. Die Etiketten können präzise plaziert werden, da kleinere Massen genauer bewegt und vor allem genauer angehalten werden können. Mit dem Verfahren läßt sich eine beliebige Oberflächenform bekleben. Es ist nicht mehr notwendig, daß die Oberfläche ausschließlich zylinderförmig oder ausschließlich eben ist, vielmehr können beide Oberflächenarten beklebt werden. Die Erzeugung der Klebeschicht kann auch bereits vor dem Aufnehmen erfolgen. Wenn das Etikett von einem Etikettenstapel abgenommen wird, wird jedoch die Klebeschicht bevorzugterweise erst nach dem Aufnehmen erzeugt.So only a small drive is required to move the pressure roller relative to the object. Even with heavy objects that have a high inertial mass, no larger drive is necessary. The labels can be placed precisely because smaller masses can be moved more precisely and, above all, can be stopped more precisely. The method can be used to glue any surface shape. It is no longer necessary for the surface to be exclusively cylindrical or exclusively flat, rather both types of surface can be glued. The adhesive layer can also be generated before recording. If the label is removed from a stack of labels, however, the adhesive layer is preferably not produced until after it has been picked up.

Mit Vorteil wird die Andruckrolle auf das Etikett aufgesetzt, in einer Richtung über das Etikett bewegt, bis sie das Etikett verläßt, und in die andere Richtung über das gesamte Etikett bewegt. Damit ist sichergestellt, daß die gesamte Oberfläche des Etiketts mit Hilfe der Andruckrolle an der Oberfläche des zu etikettierenden Gegenstands festgedrückt ist. Es kann nicht mehr passieren, daß der Anfang oder das Ende des Etiketts noch vom Gegenstand abstehen und dadurch der Gefahr des Abreißens oder des Ablösens ausgesetzt sind.The pressure roller is advantageously placed on the label, moved in one direction over the label until it leaves the label, and moved in the other direction over the entire label. This ensures that the entire surface of the label is pressed onto the surface of the object to be labeled with the aid of the pressure roller. It can no longer happen that the beginning or the end of the label still protrude from the object and are therefore exposed to the risk of tearing or peeling off.

Mit Vorteil befindet sich die Klebeschicht in keinem Verfahrensstadium oberhalb der Vorderseite des Etiketts. Das Etikett wird immer so transportiert, daß die Klebeseite nach unten weist bzw. maximal senkrecht steht. Damit wird sichergestellt, daß kein Klebstoff bzw. kein Wasser auf die Vorderseite des Etiketts gelangen können, um dort häßliche Spuren zu hinterlassen.The adhesive layer is advantageously not at any stage of the process above the front of the label. The label is always transported in such a way that the adhesive side points downwards or is at most vertical. This ensures that no adhesive or water can get on the front of the label to leave ugly marks there.

In einer bevorzugten Ausführungsform wird das Etikett zwischen der Aufnahmestation und dem Gegenstand horizontal und vertikal bewegt, wobei die Bewegungen in beiden Richtungen unabhängig voneinander erfolgen. Das Etikett wird durch eine vertikale Bewegung aufgenommen, in horizontaler Richtung zum Gegenstand hin verfahren und dort erneut durch eine vertikale Bewegung in der richtigen Höhe plaziert. Die horizontale Bewegung kann dabei so ausgelegt sein, daß das Etikett von verschiedenen Aufnahmestationen aufgenommen werden kann. Beispielsweise kann eine Aufnahmestation einen Drucker aufweisen, der bestimmte Daten des zu etikettierenden Gegenstands auf das Etikett druckt. Eine andere Aufnahmestation trägt lediglich einen Stapel gleicher Etiketten.In a preferred embodiment, the label is moved horizontally and vertically between the receiving station and the object, the movements taking place in both directions independently of one another. The label is picked up by a vertical movement, moved in the horizontal direction towards the object and then placed again at the correct height by a vertical movement. The horizontal movement can be designed so that the label can be picked up by different recording stations. For example, a receiving station can have a printer that prints certain data of the object to be labeled on the label. Another recording station only carries a stack of the same labels.

Mit Vorteil wird die Andruckrolle während des Transports des Etiketts mit dem Etikett zusammen bewegt. Dadurch läßt sich ein relativ schnelles Arbeiten sicherstellen. Die Andruckrolle steht nicht im Weg, wenn das Etikett an den Gegenstand angeklebt werden soll, d.h. das Etikett muß nicht außen um die Andruckrolle herumgeführt werden.The pressure roller is advantageously moved together with the label during the transport of the label. This ensures relatively quick work. The pinch roller is not in the way when the label is to be glued to the object, i.e. the label does not have to be passed around the outside of the pressure roller.

In einer bevorzugten Ausführungsform wird das horizontal liegende Etikett durch eine Ansaugvorrichtung aufgenommen, durch einen vertikalen Antrieb und durch einen horizontalen Antrieb in die Nähe des Gegenstandes transportiert, woraufhin die Ansaugvorrichtung das Etikett um eine horizonale Achse um einen Winkel von etwa 90° schwenkt und das Etikett am Gegenstand zur Anlage gebracht wird. Die Andruckrolle wird dann auf das Etikett gesetzt und das Etikett wird zwischen ihr und dem Gegenstand eingeklemmt. Die Ansaugvorrichtung gibt das Etikett frei und schwenkt weg, die Andruckrolle wird nach oben und nach unten über das gesamte Etikett bewegt, und das Etikett wird an der Oberfläche des Gegenstands festgedrückt.In a preferred embodiment, the horizontally lying label is picked up by a suction device, transported by a vertical drive and by a horizontal drive in the vicinity of the object, whereupon the suction device pivots the label about an horizontal axis through an angle of approximately 90 ° and the label is brought into contact with the object. The pinch roller is then placed on the label and the label is pinched between it and the object. The suction device releases the label and swings away, the pressure roller is moved up and down over the entire label, and the label is pressed onto the surface of the object.

Die Erfindung wird im folgenden anhand einer bevorzugten Ausführungsform in Verbindung mit der Zeichnung beschrieben. Darin zeigen:

The invention is described below with reference to a preferred embodiment in conjunction with the drawing. In it show:
Fig. 1
a labeling device when labeling the bale of a roll of paper,
Fig. 2
a rear view and
Fig. 3
the labeling device when labeling the end face of the paper roll.

Die Etikettierungsvorrichtung weist ein Gestell 1 auf, das auf Stützen 24-26 ruht. In dem Gestell 1 ist ein Fahrwerk 2 beweglich gelagert. Das Fahrwerk 2 ist mit einem über eine Umlenkrolle 5 geführten Riemen oder einer Kette 6 verbunden, der durch einen Motor 4 über ein Getriebe 3 angetrieben werden kann. Durch den Motor 4 läßt sich also das Fahrwerk 2 in horizontaler Richtung hin und her verfahren. Am Fahrwerk 2 ist ein Träger 8 angebracht, der mit Hilfe einer Antriebsvorrichtung 7, die im dargestellten Ausführungsbeispiel durch zwei Kolben-Zylinder-Anordnungen gebildet ist, in vertikaler Richtung bewegt werden kann. Dazu ist der Träger 8 in einer am Fahrgestell 2 angeordneten Führung 9 gelagert.The labeling device has a frame 1, which rests on supports 24-26. A chassis 2 is movably supported in the frame 1. The undercarriage 2 is connected to a belt or chain 6 which is guided over a deflection roller 5 and which can be driven by a motor 4 via a transmission 3. The motor 4 can thus move the chassis 2 back and forth in the horizontal direction. A carrier 8 is attached to the undercarriage 2 and can be moved in the vertical direction with the aid of a drive device 7, which in the exemplary embodiment shown is formed by two piston-cylinder arrangements. For this purpose, the carrier 8 is mounted in a guide 9 arranged on the chassis 2.

Am Träger 8 ist eine Etikettenaufnahmevorrichtung 10 angeordnet, die mit Hilfe eines Antriebzylinders 12 um eine Achse 11 schwenkbar ist. Die Etikettenaufnahmeeinrichtung weist dabei Sauger auf, die beim Aufnehmen des Etiketts leicht auf das Etikett gedrückt werden bzw. das Etikett berühren. Die Sauger weisen Venturi-Düsen auf, die mit Luft beaufschlagt werden, wodurch das Etikett von den Saugern angesaugt wird. Hierbei gehen die Sauger etwas zusammen und heben das Etikett an der Vorderseite von der Ablage.A label receiving device 10 is arranged on the carrier 8 and can be pivoted about an axis 11 with the aid of a drive cylinder 12. The label receiving device has suction cups that are pressed lightly onto the label or touch the label when the label is picked up. The suckers have Venturi nozzles which are pressurized with air, whereby the label is sucked in by the suckers. The suction cups go together a little and lift the label on the front of the shelf.

Am Träger 8 sind ferner zwei Lagerhebel 14 angeordnet, die an ihrem anderen Ende eine Andruckrolle 13 tragen. Die Lagerhebel 14 sind um eine im Träger 8 gelagerte Schwenkachse 15 verschwenkbar und mit dieser über Drehfedern 31 verbunden. Mit der Schwenkachse 15 ist ein Antriebshebel 16 drehfest verbunden. Dieser schließt mit den Lagerhebeln 14 in Neutralstellung der Drehfedern 31 einen spitzen Winkel ein. An der anderen Seite des Antriebshebels 16 greift ein Andruckrollenschwenkantrieb 17 an, der ebenfalls am Träger 8 befestigt ist. Mit Hilfe des Andruckrollenschwenkantriebs 17 läßt sich die Andruckrolle 13 um einen Winkel zwischen 120° und 180° um die Schwenkachse 15 verschwenken.Furthermore, two bearing levers 14 are arranged on the carrier 8, which bear a pressure roller 13 at their other end. The bearing levers 14 can be pivoted about a pivot axis 15 mounted in the carrier 8 and are connected to the latter via torsion springs 31. A drive lever 16 is connected in a rotationally fixed manner to the pivot axis 15. This includes an acute angle with the bearing levers 14 in the neutral position of the torsion springs 31. On the other side of the drive lever 16, a pinch roller swivel drive 17 engages, which is also attached to the carrier 8. With the help of the pinch roller pivot drive 17, the pinch roller 13 can be pivoted through an angle between 120 ° and 180 ° about the pivot axis 15.

Ferner sind zwei Vorbereitungsstationen 21, 22 vorgesehen, auf denen jeweils eine Etikettenaufnahmeposition 19, 20 angeordnet ist. Auf der Etikettenaufnahmeposition 19 befindet sich ein Etikett 18. Die Vorbereitungsstation 21 ist dabei ein Drucker, der Gewicht und Verpackungsdatum der Papierrolle auf das Etikett druckt.Furthermore, two preparation stations 21, 22 are provided, on each of which a label receiving position 19, 20 is arranged. A label 18 is located on the label receiving position 19. The preparation station 21 is a printer that prints the weight and packaging date of the paper roll on the label.

Auf einem Tisch 30, 30′ können der Etikettierungsvorrichtung Papierrollen 27-29 verschiedener Größen zugeführt werden. Dabei spielt es keine Rolle, ob der Ballen, d.h. die Zylindermantelfläche der Papierrolle, oder die Stirnseite der Papierrolle etikettiert werden soll. In jedem Fall arbeitet die Etikettierungsvorrichtung auf die gleiche Art und Weise.On a table 30, 30 'the labeling device paper rolls 27-29 of different sizes can be supplied. It does not matter whether the bale, i.e. the cylindrical surface of the paper roll, or the end face of the paper roll is to be labeled. In any case, the labeling device works in the same way.

Zum Aufnehmen eines Etiketts wird der Träger 8 vertikal nach oben und das Fahrgestell 2 horizontal nach rechts verfahren. Die Etikettenaufnahmeeinrichtung 10 muß dabei höher liegen als das Etikett 18. Die horizontale Bewegung und die vertikale Bewegung können dabei gleichzeitig erfolgen, sie sind aber in jedem Fall unabhängig voneinander. Wenn sich das Fahrwerk 2 über der Etikettenaufnahmeposition 19 befindet, wird der Träger 8 durch die vertikale Antriebsvorrichtung 7 abgesenkt, bis die Sauger der Etikettenaufnahmeeinrichtung 10 das Etikett berühren. Durch Ansaugen wird das Etikett 18 von der Aufnahmeposition 19 abgehoben. Danach wird das Fahrwerk 2, angetrieben durch den Motor 4, in horizontaler Richtung wieder nach links verfahren, bis es vor der zu etikettierenden Papierrolle 27, 28 bzw. 29 angehalten wird. Auf dem Weg dorthin hat das Etikett eine Befeuchtungseinrichtung 23 passiert. Die Befeuchtungseinrichtung hat dabei entweder Wasser auf die Unterseite des Etiketts gesprüht, wenn gummierte Etiketten verwendet werden, oder sie hat mit Hilfe einer Düse oder mit Hilfe einer Bürste bzw. Walze eine Leimschicht auf die Unterseite des Etiketts aufgebracht. Andere Möglichkeiten, wie Erhitzen eines wärmelöslichen Klebstoffs oder Besprühen einer vorbereiteten Schicht mit einem Lösungsvermittler sind ebenfalls denkbar.To hold a label, the carrier 8 is moved vertically upwards and the chassis 2 horizontally to the right. The label receiving device 10 must be higher than the label 18. The horizontal movement and the vertical movement can take place simultaneously, but they are independent of one another in any case. When the undercarriage 2 is above the label receiving position 19, the carrier 8 is lowered by the vertical drive device 7 until the suction cups of the label receiving device 10 touch the label. The label 18 is lifted from the receiving position 19 by suction. Then the carriage 2, driven by the motor 4, is moved to the left again in the horizontal direction until it is stopped in front of the paper roll 27, 28 or 29 to be labeled. On the way there, the label has passed a moistening device 23. The moistening device has either sprayed water onto the underside of the label if rubberized labels are used, or has applied a layer of glue to the underside of the label with the aid of a nozzle or with the aid of a brush or roller. Other ways like Heating a heat-soluble adhesive or spraying a prepared layer with a solubilizer are also conceivable.

Nach dem Passieren der Befeuchtungseinrichtung 23 wird die Etikettenaufnahmeeinrichtung 10 durch den Antrieb 12 um die Achse 11 geschwenkt, so daß das Etikett aus der waagrechten in eine annähernd senkrechte Lage gebracht wird. Das Fahrwerk 2 kann nun den Träger 8 so lange horizontal nach links verfahren, bis das Etikett an der Oberfläche der zu etikettierenden Papierrolle anliegt. Das Fahrwerk 2 kann jedoch auch bereits vorher angehalten werden, so daß das senkrechtstehende Etikett noch einen geringen Abstand von der zu etikettierenden Oberfläche aufweist. Nun wird die Andruckrolle 13 durch den Andruckrollenschwenkantrieb 17 um die Achse 15 gegen die Papierrolle geschwenkt und klemmt das Etikett zwischen sich und der Papierrolle ein. Die Sauger der Etikettenaufnahmeeinrichtung 10 blasen das Etikett ab und schwenken wieder in ihre ursprüngliche, d.h. waagrechte Stellung. Nach diesem Vorgang wird der Träger 8 durch den Antrieb 7 vertikal nach oben verfahren. Der Andruckrollenschwenkantrieb 17 hält dabei einen Druck auf den Antriebshebel 16 aufrecht, so daß die Andruckrolle 13 immer gegen die Papierrolle 27, 28 bzw. 29 gedrückt wird. Auch wenn einen Ballenoberfläche beklebt wird, kann die Andruckrolle der Kontur der Oberfläche folgen.After passing through the moistening device 23, the label receiving device 10 is pivoted about the axis 11 by the drive 12, so that the label is brought out of the horizontal into an approximately vertical position. The undercarriage 2 can now move the carrier 8 horizontally to the left until the label rests on the surface of the paper roll to be labeled. However, the undercarriage 2 can also be stopped beforehand, so that the vertical label is still a short distance from the surface to be labeled. Now the pinch roller 13 is pivoted about the axis 15 against the paper roll by the pinch roller swivel drive 17 and clamps the label between it and the paper roll. The suckers of the label receiving device 10 blow off the label and pivot back into their original, i.e. horizontal position. After this process, the carrier 8 is moved vertically upwards by the drive 7. The pinch roller pivot drive 17 maintains a pressure on the drive lever 16, so that the pinch roller 13 is always pressed against the paper roll 27, 28 or 29. Even if a bale surface is stuck on, the pressure roller can follow the contour of the surface.

Nach dem Erreichen der oberen Stellung wird der Träger 8 durch seinen Antrieb 7 vertikal nach unten verfahren. Die Andruckrolle 13 behält dabei in jedem Fall den Kontakt mit der Oberfläche der zu etikettierenden Papierrolle 27, 28 bzw. 29. Durch diesen Vorgang wird das Etikett vollständig an der Papierrolle angewalzt bzw. angeklebt. Es ist sichergestellt, daß das gesamte Etikett von der Andruckrolle 13 überstrichen worden ist.After reaching the upper position, the carrier 8 is moved vertically downward by its drive 7. In this case, the pressure roller 13 always remains in contact with the surface of the paper roll 27, 28 or 29 to be labeled. This process completely rolls or glues the label onto the paper roll. It is ensured that the entire label has been covered by the pressure roller 13.

Durch den Andruckrollenschwenkantrieb 17, der z.B. durch einen Pneumatik- oder Hydraulik-Zylinder gebildet werden kann, kann sich die Andruckrolle 13 praktisch jeder beliebigen Kontur anpassen. Bei einer geraden Fläche, z.B. die Stirnseite einer Papierrolle, bleibt der Andruckrollenschwenkantrieb 17 praktisch in seiner einmal ausgefahrenen Position, wenn der Träger 8 vertikal nach oben und unten verfahren wird. Beim Aufbringen eines Etiketts auf die Zylindermantelfläche einer Papierrolle wird der Andruckrollenschwenkantrieb 17 beim Bewegen der Andruckrolle 8 über die Oberfläche der Papierrolle 27, 28 eingefahren und danach wieder ausgefahren.By the pressure roller swivel drive 17, which e.g. can be formed by a pneumatic or hydraulic cylinder, the pressure roller 13 can adapt to practically any contour. With a straight surface, e.g. the end of a paper roll, the pinch roller pivot drive 17 practically remains in its extended position when the carrier 8 is moved vertically up and down. When a label is applied to the cylindrical surface of a paper roll, the pinch roller pivot drive 17 is retracted when the pinch roller 8 is moved over the surface of the paper roll 27, 28 and then extended again.

Nach dem Aufklebevorgang auf die Papierrolle schwenkt die Andruckwalze 13 wieder in ihre Grundstellung, und der Träger 8 wird nach oben verfahren. Anschließend kann das Fahrwerk 2 horizontal in seine Bereitschaftsstellung zur Aufnahme des nächsten Etiketts von der Aufnahmeposition 19 verfahren werden. Alle Fahrbewegungen bzw. alle Hub- und Schwenkbewegungen können mit Hilfe von elektrischen, pneumatischen oder hydraulischen Motoren durchgeführt werden.After the gluing process on the paper roll, the pressure roller 13 swivels back into its basic position, and the carrier 8 is moved upwards. The undercarriage 2 can then be moved horizontally into its ready position for receiving the next label from the receiving position 19. All travel movements or all lifting and swiveling movements can be carried out with the help of electric, pneumatic or hydraulic motors.

Wie aus Fig. 1 und 3 ersichtlich, können mit der gleichen Vorrichtung sowohl die Etiketten am Ballen als auch an der Stirnseite einer Papierrolle angebracht werden. Weiterhin braucht die Papierrolle während des Aufklebens von Etiketten nicht gedreht zu werden.As can be seen from FIGS. 1 and 3, the same device can be used to apply both the labels to the bale and to the front of a paper roll. Furthermore, the paper roll does not need to be rotated during the sticking of labels.

Weiterhin können Gegenstände unterschiedlichster Größenordnung verarbeitet werden. Wie aus Fig. 1 ersichtlich, müssen bei einer kleineren Rolle 27 lediglich das Fahrwerk 2 weiter nach links und der Träger 8 weiter nach unten verfahren werden, wie dies gestrichelt angedeutet ist.Objects of various sizes can also be processed. As can be seen from FIG. 1, in the case of a smaller roller 27, only the undercarriage 2 has to be moved further to the left and the carrier 8 further downward, as is indicated by dashed lines.

Die Etikettenaufnahmepositionen 19, 20 können in unterschiedlicher Höhe auf ihren Vorbereitungsstationen 21, 22 angeordnet sein. So ist es z.B. möglich, die Vorbereitungsstation 21 mit einem Drucker auszurüsten, der eine größere Bauhöhe hat als die Vorbereitungsstation 22, die beispielsweise nur aus einem Tisch besteht, auf dem Etiketten gestapelt werden. Die Vorrichtung läßt sich somit sehr flexibel handhaben.The label receiving positions 19, 20 can be arranged at different heights on their preparation stations 21, 22. So it is e.g. possible to equip the preparation station 21 with a printer that has a greater overall height than the preparation station 22, which for example consists of only one table, on which labels are stacked. The device can thus be handled very flexibly.
