Description

Die Erfindung betrifft eine Etikettiervorrichtung nach den Merkmalen des Oberbegriffs des Anspruchs 1 und ein Verfahren zum Etikettieren nach den Merkmalen des Oberbegriffs des Anspruchs 9. Aus der JP 2004-262 512 ist eine Vorrichtung und ein Verfahren dieses Art bekannt.The invention relates to a labeling device according to the features of the preamble of claim 1 and a method of labeling according to the features of the preamble of claim 9. From the JP 2004-262 512 a device and a method of this kind is known.

Bei Etikettiervorrichtungen ergibt sich in der Praxis das Problem, dass das Etikett exakt zu dem zu etikettierenden Produkt auszurichten.In labeling devices arises in practice the problem that align the label exactly to the product to be labeled.

So zeigt beispielsweise die EP 1 932 767 B1 eine Etikettiervorrichtung eines Verpackungssystems, bei der die Position des Etiketts gemäß der Produktausrichtung verändert wird.For example, shows the EP 1 932 767 B1 a labeling device of a packaging system, wherein the position of the label is changed according to the product orientation.

Bei dieser vorgeschlagenen Lösung ist es notwendig einen Etikettierer einzusetzen, der das Etikett entsprechend der Fehlausrichtung des zu etikettierenden Produkts verschieben kann. Solche Etikettier sind konstruktiv relativ aufwändig und zudem im Betrieb langsam, so dass die zu erzielende Etikettiergeschwindigkeit oftmals hinter den Erwartungen zurückbleibt.In this proposed solution, it is necessary to use a labeler that can move the label according to the misalignment of the product to be labeled. Such labeling are structurally relatively complex and also slow in operation, so that the labeling speed to be achieved often falls short of expectations.

Der Erfindung liegt die Aufgabe zugrunde eine Vorrichtung und ein Verfahren zum Etikettieren zu schaffen, welches auf konstruktiv einfache Art und Weise eine zuverlässige und dabei leistungsfähige Etikettierung von Verpackungen ermöglicht.The invention has for its object to provide a device and a method for labeling, which allows a structurally simple way reliable and efficient labeling of packaging.

Diese Aufgabe wird erfindungsgemäß durch eine Vorrichtung mit den Merkmalen des Anspruchs 1 und ein Verfahren mit den Merkmalen des Anspruchs 9 gelöst.This object is achieved by a device having the features of claim 1 and a method having the features of claim 9.

Über eine Bilderkennungsvorrichtung wird die Position einer Verpackung erfasst und ein Korrektursignal ermittelt, welches an einen Drucker gesendet wird. Auf Basis des Korrektursignales variiert der Drucker das Druckbild auf dem Etikett entsprechend der Lage der Verpackung. Anschließend wird das Etikett von einem Applikator an dem Drucker aufgenommen und auf der Verpackung angebracht. Der Applikator für die Etiketten kann dabei als dem Fachmann aus der Praxis bekannter Stempelapplikator, oder als Blasapplikator oder als Rotationsapplikator ausgebildet sein. Der Applikator übernimmt das Etikett von dem Drucker und appliziert das Etikett auf der Verpackung immer an der gleichen Stelle. Der Stempelapplikator verfährt dazu einen Stempel, der das Etikett hält, linear von oben nach unten bis auf die Verpackung. Der Blasapplikator bläst dazu das Etikett mittels Druckluft auf die Verpackung und der Rotationsapplikator appliziert das Etikett mittels eines rotierenden Armes auf der Verpackung. Ein solcher Applikator appliziert das Etikett dabei immer an der gleichen Stelle der Verpackung. Eine Verschiebung des Etiketts durch den Applikator ist nicht notwendig. Etwaige Lagetoleranzen der Verpackung werden über die Verschiebung des Druckbildes auf dem Etikett ausgeglichen.Via an image recognition device, the position of a package is detected and a correction signal is determined, which is sent to a printer. Based on the correction signal, the printer varies the printed image on the label according to the position of the package. The label is then picked up by an applicator on the printer and mounted on the package. The applicator for the labels can be designed as a person skilled in the art from known stamp applicator, or as Blasapplikator or as a rotary applicator. The applicator takes over the label from the printer and always applies the label on the packaging in the same place. The stamp applicator moves to a stamp that holds the label, linear from top to bottom down to the packaging. The blow applicator blows the label onto the packaging by means of compressed air and the rotary applicator applies the label to the packaging by means of a rotating arm. Such an applicator always applies the label in the same place of the packaging. A displacement of the label by the applicator is not necessary. Any positional tolerances of the packaging are compensated by the displacement of the printed image on the label.

Es ist vorgesehen, dass die Etiketten größere Abmessungen aufweisen, als das Druckbild. So kann das Druckbild auf dem Etikett um eine bestimmte Strecke in X-Richtung oder in Y-Richtung verschoben werden. Es ist auch möglich, dass das Druckbild von dem Drucker um einen bestimmten Winkelbetrag im Uhrzeigersinn oder entgegen des Uhrzeigersinns gedreht wird, um Lagetoleranzen der Verpackung auszugleichen.It is intended that the labels have larger dimensions than the printed image. This allows the printed image on the label to move a certain distance in the X direction or in the Y direction be moved. It is also possible that the print image is rotated by the printer by a certain angle clockwise or counterclockwise to compensate for positional tolerances of the package.

In einer Ausführung ist vorgesehen, dass der Drucker einen Speicher aufweist, in dem mehrere Etikettenlayouts abgespeichert sind, wobei jedes Etikettenlayout ein um einen bestimmten Korrekturwert verschobenes Druckbild aufweist. Der Drucker kann dann dem Korrektursignal entsprechend das Layout aussuchen welches dem gewünschten Druckbild entspricht bzw. nahekommt. Dadurch wird ein schnellerer Druckvorgang ermöglicht, da nicht bei jedem Druckvorgang das gesamte Layout neu berechnet bzw. zuerst an den Drucker übertragen werden muss.In one embodiment, it is provided that the printer has a memory in which a plurality of label layouts are stored, each label layout having a printed image shifted by a specific correction value. The printer can then select the correction signal according to the layout which corresponds to the desired print image or comes close. This allows for faster printing because the entire layout does not have to be recalculated or transferred to the printer every time you print.

Als Drucker können bekannte Thermotransferdrucker oder auch Tintenstrahldrucker zum Einsatz kommen.As a printer, known thermal transfer printer or ink jet printer can be used.

Es ist in einer Ausführung vorgesehen, dass das Druckbild des Etiketts einen variablen Wert, insbesondere einen Gewichtswert oder einen Portobetrag beinhaltet, der sich von Verpackung zu Verpackung ändern kann. Dieser Wert wird von einer Messeinrichtung, insbesondere einer Waage, ermittelt und an den Drucker übertragen. Dieser Wert kann von dem Drucker als Zahlenwert oder als Strichcode bzw. 3D-Code in das Druckbild integriert werden.It is provided in an embodiment that the printed image of the label includes a variable value, in particular a weight value or a postage amount, which may change from one package to another. This value is determined by a measuring device, in particular a balance, and transmitted to the printer. This value can be integrated by the printer as a numeric value or as a barcode or 3D code into the print image.

Es ist in einer Ausführung vorgesehen, dass die Verpackungen auf einem Transportband transportiert werden. Dabei kommt als Kamera für die Bilderkennungseinrichtung eine optische Kamera zum Einsatz, die im sichtbaren Bereich oder auch im Infrarotbereich aufnehmen kann. Die Kamera kann vorteilhafterweise als Zeilenkamera ausgebildet sein, um Bauraum zu sparen. Ein auf der Verpackung vorhandener Druckbereich oder Druckrahmen kann von der Kamera detektiert und als Referenz für die Ermittlung des Korrektursignals verwendet werden.It is provided in an embodiment that the packages are transported on a conveyor belt. Here comes as a camera for the image recognition device an optical Camera for use, which can record in the visible range or in the infrared range. The camera can be advantageously designed as a line scan camera to save space. An existing on the packaging printing area or printing frame can be detected by the camera and used as a reference for the determination of the correction signal.

Um eine zuverlässige Bilderkennung zu ermöglichen kann vorgesehen sein, dass die Bilderkennungsvorrichtung eine Beleuchtungsvorrichtung aufweist, die den zu erfassenden Bereich ausleuchtet und damit die Bilderkennung unabhängig von den vorherrschenden Lichtverhältnissen macht.In order to enable reliable image recognition it can be provided that the image recognition device has a lighting device which illuminates the area to be detected and thus makes the image recognition independent of the prevailing lighting conditions.

In einer Ausführung kann vorgesehen sein, dass unabhängig von der Lage der Verpackung nach dem Applizieren des Etiketts das Druckbild innerhalb des auf der Verpackung angeordneten Druckbereichs oder des Druckrahmens angeordnet ist. Um einen optisch ansprechenden Eindruck zu erzielen kann vorgesehen sein, dass die Etiketten ein durchsichtiges Trägermaterial aufweisen, so dass der Druckrahmen oder der Druckbereich der Verpackung durch das Etikett hindurch zu erkennen sind. Alternativ kann auch vorgesehen sein, dass der Drucker den Druckrahmen mit dem Layout auf das Etikett aufdruckt.In an embodiment it can be provided that, independently of the position of the packaging after the application of the label, the printed image is arranged within the printing region or the printing frame arranged on the packaging. In order to achieve a visually appealing impression it can be provided that the labels have a transparent carrier material, so that the printing frame or the printing area of the packaging can be seen through the label. Alternatively, it can also be provided that the printer prints the printing frame with the layout on the label.

Eine Anwendung der Erfindung ist insbesondere bei der Etikettierung von verpackten Gütern mit unregelmäßigen Abmessungen, wie z. B. bei in Folie verpacktem Geflügel vorgesehen. Jedoch kann die Erfindung auch bei Verpackungen mit regelmäßigen Abmessungen zum Einsatz kommen, um beispielsweise Lagetoleranzen, die beim Transport der Verpackungen auftreten können, auszugleichen.An application of the invention is particularly in the labeling of packaged goods with irregular dimensions, such. B. provided in foil-packaged poultry. However, the invention can also be used in packages of regular dimensions to For example, to compensate for positional tolerances that may occur during transport of the packaging.

Weitere Ausführungsbeispiele der Erfindung sind in den Figuren dargestellt und der dazugehörenden Beschreibung beschrieben.Further embodiments of the invention are illustrated in the figures and the associated description.

In den Figuren 1 und 2 ist jeweils eine erfindungsgemäße Etikettiervorrichtung 1 dargerstellt. Ein Gestell 12, welches über höheneinstellbare Füße 13 aufgestellt ist, wird ein Transportband 11 geführt. Das Transportband 11 transportiert verpackte Lebensmittel in der Darstellung der Figuren von rechts nach links. Als einzeln verpacktes Lebensmittel wird beispielsweise in Folie verpacktes Geflügel transportiert.In the FIGS. 1 and 2 in each case a labeling device 1 according to the invention is shown. A frame 12, which is placed on height-adjustable feet 13, a conveyor belt 11 is guided. The conveyor belt 11 transports packaged food in the representation of the figures from right to left. As individually packaged food, for example, packaged in foil poultry is transported.

Weiter haltert das Gestell 12 am Anfang der Transportvorrichtung eine Leitvorrichtung für die Verpackungen, bestehend aus zwei trichterförmig verlaufenden Leitblechen 14a und 14b. Diese Leitvorrichtung sorgt für eine grobe Ausrichtung der transportierten Verpackungen. Von der Leiteinrichtung gelangen die Verpackungen nach dem passieren einer Lichtschranke zu einer Bilderkennungsvorrichtung 2, die oberhalb des Transportbandes angeordnet ist. Anschließend ist in Transportrichtung eine Waage 6 mit einer Wägezelle 61 zum Erfassen des Gewichts der Verpackungen angeordnet. Weiter in Transportrichtung passieren die Verpackungen einen Etikettenapplikator 3 mit einem Drucker 4. Der Applikator bringt ein auf Basis der von der Waage 2 ermittelten Wägedaten und der von der Bilderkennungsvorrichtung 2 ermittelten Korrektursignale von dem Drucker 4 bedrucktes Etikett auf der Verpackung an. Ein unterhalb des Transportbandes 11 angeordneter Schaltkasten 15 beinhaltet eine Steuerungsvorrichtung, die mit den einzelnen Komponenten der Etikettiervorrichung 1 verbunden ist, sowie eine Stromversorgung.Next holds the frame 12 at the beginning of the transport device a guide device for the packaging, consisting of two funnel-shaped baffles 14 a and 14 b. This guide device ensures a coarse alignment of the transported packaging. From the guide, the packages arrive after passing a light barrier to an image recognition device 2, which is arranged above the conveyor belt. Subsequently, a balance 6 is arranged with a weighing cell 61 for detecting the weight of the packaging in the transport direction. Further, in the transport direction, the packages pass through a label applicator 3 with a printer 4. The applicator applies a label on the package printed by the printer 4 on the basis of the weighing data determined by the balance 2 and the correction signals determined by the image recognition device 2. A control box 15 disposed below the conveyor belt 11 includes a control device connected to the individual components of the labeling apparatus 1 and a power supply.

Über ein an der Bilderkennungsvorrichtung 2 angeordnetes Display 21 kann die Etikettiervorrichtung bedient werden. Zugleich kann an dem Display das Ergebnis der Bilderkennungsvorrichtung oder ein Etikettenlayout angezeigt werden.About a arranged on the image recognition device 2 display 21, the labeling can be operated. At the same time, the result of the image recognition device or a label layout can be displayed on the display.

Der schematische Aufbau der Bilderkennungsvorrichtung 2 ist aus der Figur 3 ersichtlich. Eine Zeilenkamera 22 nimmt die Bildinformation auf, wobei die aufzunehmende Bildzeile mittels zweier V-förmig angeordneter Lichtquellen 23 und 24 ausgeleuchtet wird. Mittels einer unterhalb der Kamera 22 angeordneten Blende werden Störeinflüsse ausgeblendet. Eine Haube umschließt die Bilderkennungsvorrichtung 2 und schirmt zusätzliche Störeinflüsse ab.The schematic structure of the image recognition device 2 is shown in FIG FIG. 3 seen. A line scan camera 22 captures the image information, with the image line to be captured is illuminated by means of two light sources 23 and 24 arranged in a V-shape. By means of an aperture arranged below the camera 22, interference effects are masked out. A hood encloses the image recognition device 2 and shields additional interference.

Die zeilenkamera nimmt das Bild der unter der Kamera 22 von dem Transportband 11 kontinuierlich transportierten Verpackungen 5 auf. Dabei erfolgt der Bildaufbau, indem die Zeilenkamera 22 zeitlich unmittelbar aufeinanderfolgend getaktet einzelne Bildzeilen aufnimmt, während das Transportband 11 den Artikel 5 mit konstanter Geschwindigkeit weitertransportiert. Durch aneinanderfügen der einzeln aufgenommenen Zeilen erhält man dann ein Gesamtbild des Artikels 5.The line camera captures the image of the packaging 5 continuously transported by the conveyor belt 11 under the camera 22. In this case, the image structure is carried out by the line scan camera 22 temporally immediately successively clocked records individual image lines, while the conveyor belt 11 further transports the article 5 at a constant speed. By joining the individually recorded lines one then obtains an overall picture of the article 5.

Ein Beispiel eines aufgenommenen Bildes ist in der Figur 4 dargestellt. Dort sind einzelne, in Folie verpackte Hähnchen dargestellt, die nacheinander auf dem Transportband 11Transportiert werden. Auf der Oberseite der verpackten Hähnchen ist auf der Folie der Druckbereich 41 ersichtlich, der von der Bilderkennungsvorrichtung 2 ausgewertet wird. Entsprechend der Lage des Druckbereichs 41 generiert die Bilderkennungsvorrichtung 2 ein Korrektursignal, basierend auf einer x-Verschiebung und/oder Y-Verschiebung des Druckbereichs 41.An example of a captured image is in the FIG. 4 shown. There, individual, packaged in foil chickens are shown, which are transported one after the other on the conveyor belt 11. On the top of the packaged chicken, the printing area 41, which is evaluated by the image recognition device 2, can be seen on the film. According to the position of the printing area 41, the image recognition device 2 generates a correction signal based on an x-shift and / or Y-shift of the printing area 41.

Der Druckbereich 41 ist als farblich abgesetzter Bereich ausgebildet, der auf der Oberseite der Verpackung 5 angebracht ist und von der Bilderkennungsvorrichtung 2 ausgewertet wird. Ein Druckbild 71 eines anzubringenden Etiketts soll innerhalb des Druckbereichs zu liegen kommen.The printing area 41 is formed as a contrasting area, which is mounted on the top of the package 5 and the image recognition device. 2 is evaluated. A printed image 71 of a label to be attached should come to rest within the printing area.

In der Figur 5 ist eine Auswahl an einzelnen Etiketten 7 mit unterschiedlichen Etikettenlayouts 7a und 7b und 7c dargestellt. Der Drucker weist einen Speicher auf, in dem mehrere dieser Layouts vorab abgespeichert sind. Die einzelnen Layouts können am Display 21 erstellt oder bearbeitet werden, oder auch über eine Datenverbindung in den Speicher des Druckers eingespielt werden. Das Druckbild 71 ist in jedem Etikett gleich gestaltet. Die Position des Druckbilds ist von Layout zu Layout unterschiedlich angeordnet. Das Layout 7a zeigt eine Positionierung des Druckbildes ganz am linken Rand des Etiketts 7. Das Layout 7b zeigt eine mittige Positionierung des Druckbilds 71 während das Layout 7c eine am rechten Rand des Etiketts 7 angeordnete Positionierung des Druckbildes 71 zeigt. Durch die Verschiebung des Layouts auf dem Etikett können Lagetoleranzen der Verpackung 5 bzw. des Druckrahmens 41 ausgeglichen werden.In the FIG. 5 a selection of individual labels 7 with different label layouts 7a and 7b and 7c is shown. The printer has a memory in which several of these layouts are pre-stored. The individual layouts can be created or edited on the display 21, or also be imported via a data connection in the memory of the printer. The print image 71 is the same in each label. The position of the print image varies from layout to layout. The layout 7a shows a positioning of the print image at the very left edge of the label 7. The layout 7b shows a central positioning of the print image 71 while the layout 7c shows a positioning of the print image 71 arranged at the right edge of the label 7. By shifting the layout on the label, positional tolerances of the package 5 or the printing frame 41 can be compensated.

Beim Druck ruft der Drucker 4 das zu dem Korrektursignal der Bilderkennungsvorrichtung 2 passende Layout ab und bedruckt das Etikett entsprechend. Anschließend wird das Etikett von dem Applikator 3 auf die Verpackung 5 appliziert.When printing, the printer 4 retrieves the layout matching the correction signal of the image recognition device 2 and prints the label accordingly. Subsequently, the label is applied by the applicator 3 to the package 5.
