Description

Stand der TechnikState of the art

Die Erfindung geht aus von einer Vorrichtung zur Erfassung von Erkennungsmerkmalen an mindestens einer Seite von kastenartigen oder fassartigen Leergutgebinden, die auf einer Transporteinrichtung in einer Transportrichtung transportiert werden.The invention is based on a device for detecting identification features on at least one side of box-type or barrel-type empties containers which are transported on a transport device in a transport direction.

Derartige Vorrichtungen werden beispielsweise in Leergut-Rücknahmeautomaten eingesetzt. Sie dienen dazu, Leergutgebinde, insbesondere einzelne Flaschen oder Dosen sowie mit Flaschen gefüllte Getränkekisten und Partyfässer, aufzunehmen und in Abhängigkeit von charakteristischen Merkmalen der eingegebenen Leergutbehälter oder Leergutgebinde ein Pfand an den Benutzer auszugeben. Bei kastenartigen und fassartigen Leergutgebinden wie Getränkekisten und Partyfässer werden als charakteristische Merkmale beispielsweise eine auf die Seite des Leergutgebindes aufgebrachte Kennzeichnung, die Vollständigkeit des Gebindes, die darin enthaltene Flaschensorte, eventuelle Fremdflaschen, quer- oder längsliegende Flaschen, Flaschen, welche mit ihrer Öffnung nach unten in der Getränkekiste ausgerichtet sind, beschädigte Flaschen, Flaschen mit oder ohne Verschluss, teilweise oder ganz gefüllte Flaschen, Fremdkörper zwischen den Flaschen, die Form und eventuelle Beschädigungen der Getränkekiste erfasst. Die Kennzeichnung des Leergutgebindes an der Seite wird durch eine Vorrichtung erfasst, welche das auf einer Transporteinrichtung beförderte Leergutgebinde seitlich beleuchtet und das von der Oberfläche des Leergutgebindes reflektierte Licht erfasst und auswertet. Die übrigen Merkmale werden durch eine separate Vorrichtung erfasst, die die Leergutgebinde von oben beleuchtet und die Reflektionen auswertet. Häufig wird zusätzlich das Gewicht eines Leergutgebindes bestimmt. Erfüllt ein Leergutgebinde nicht die für die Annahme des Leergutes vorgegebenen Kriterien, so wird das Leergutgebinde durch den Leergut-Rücknahmeautomaten wieder an den Kunden zurückgegeben. Durch die Auswertung der Kennzeichnung auf den Seiten eines kastenartigen oder fassartigen Leergutgebindes kann beispielsweise festgestellt werden, ob das Leergutgebinde durch den Betreiber des Leergut-Rücknahmeautomaten angenommen wird. Die Kennzeichnung enthält beispielsweise die Marke des zugehörigen Getränkeherstellers oder - abfüllers. Der Betreiber des Leergut-Rücknahmeautomaten kann auf diese Weise verhindern, dass Kunden Leergutgebinde von Herstellern oder Abfüllern zurückgeben, die er in seinem Geschäft nicht vertreibt.Such devices are used for example in reverse vending machines. They serve empties containers, in particular individual bottles or cans and filled with bottles crates and party kegs, record and issue a deposit to the user depending on the characteristics of the entered empty containers or empties containers. In box-like and barrel-type empties such as crates and party kegs are characteristic features such as applied to the side of the empties label, the completeness of the container, the bottles contained therein, any foreign bottles, transverse or longitudinal bottles, bottles, which with their opening down aligned in the crate, damaged bottles, bottles with or without closure, partially or completely filled bottles, foreign bodies between the bottles, the shape and possible damage to the crate recorded. The identification of the empties container on the side is detected by a device which illuminates the empties container transported on a transport device laterally and detects and evaluates the light reflected from the surface of the empties container. The remaining features are detected by a separate device that illuminates the empties containers from above and evaluates the reflections. Often, the weight of an empties container is also determined. If an empties container does not fulfill the criteria for accepting the empties, then this becomes Returned empty containers through the reverse vending machine to the customer. By evaluating the marking on the sides of a box-like or barrel-type empties container, it can be determined, for example, whether the empties container is accepted by the operator of the reverse vending machine. The label includes, for example, the brand of the associated beverage manufacturer or bottler. In this way, the operator of the reverse vending machine can prevent customers from returning empty packaging containers from manufacturers or bottlers, which he does not sell in his shop.

Neben Leergutrücknahmeautomaten finden derartige Vorrichtungen auch in Abfüllbetrieben Anwendung, um das angelieferte Leergut einer Eingangskontrolle zu unterziehen. Dabei werden fehlerhafte Leergutgebinde ausgesondert, um den störungsfreien Wiedereinsatz der Leergutgebinde zu gewährleisten.In addition to reverse vending machines such devices find application in bottling plants to subject the delivered empties an incoming inspection. In the process, faulty empties containers are sorted out to ensure trouble-free reuse of the empties containers.

Bei dem Einsatz einer Vorrichtung zum Abtasten der Seiten von kastenartigen oder fassartigen Leergutgebinden ist dafür Sorge zu tragen, dass diese den Einsatz von Vorrichtungen zum Abtasten der Oberseite der Leergutgebinde nicht beeinträchtigen. Da beide Vorrichtungen jeweils für sich unterschiedliche Merkmale eines Leergutgebindes erfassen, werden häufig beide Vorrichtungen kumulativ eingesetzt. Um die Erfassung der Merkmale zu beschleunigen und um die Strecke, auf der die Erfassung erfolgt, möglichst kurz zu gestalten, befinden sich die beiden Vorrichtungen in der Regel unmittelbar nebeneinander und ermitteln gleichzeitig die jeweiligen Merkmale. Bei beiden Vorrichtungen werden hierzu die ihnen jeweils zugewandten Seiten der Leergutgebinde beleuchtet. Als nachteilig erweist sich dabei, dass die Beleuchtung der Seiten eines Leergutgebindes dazu führt, dass bei der Abtastung der Oberseite des Leergutgebindes nicht mehr exakt zwischen dem Leergutgebinde und seiner Umgebung unterschieden werden kann. Dies kann zu einer Verfälschung des Ergebnisses der Abtastung führen.When using a device for scanning the sides of box-like or barrel-type empties containers, care must be taken that they do not interfere with the use of devices for scanning the top of the empty containers. Since both devices each seize different characteristics of an empties package, often both devices are used cumulatively. In order to accelerate the detection of the features and to make the track on which the detection takes place as short as possible, the two devices are usually next to each other and simultaneously determine the respective features. In both devices for this purpose they each facing sides of the empty containers are illuminated. It proves to be disadvantageous that the illumination of the sides of an empties container leads to the fact that when scanning the top of the empties container can no longer be distinguished exactly between the empties container and its environment. This can lead to a falsification of the result of the scan.

Um zwischen dem von der nach oben weisenden Seite eines Leergutgebindes und dem von seiner Seite reflektierten Licht unterscheiden zu können, werden Laser unterschiedlicher Wellenlängen zur Beleuchtung eingesetzt. Als Nachteil erweist sich jedoch hierbei, dass die mit Lasern ausgestatteten Vorrichtungen zur Abtastung der Oberseite eines Leergutgebindes aufgrund ihres apparativen Aufwandes und der für die Abtastung notwendigen Strecke hinsichtlich ihres Baumasses derart lang sind, dass sie nicht in dem bei einem potentiellen Anwender zur Verfügung stehenden Raum aufgestellt werden können.In order to be able to distinguish between the light reflected from the upwardly facing side of an empties container and the light reflected from its side, lasers of different wavelengths are used for illumination. However, a disadvantage in this case proves that the devices equipped with lasers for scanning the top of an empties container due to their equipment cost and necessary for scanning track in terms of their construction dimensions are so long that they are not in the space available to a potential user can be set up.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Abtasten mindestens einer Seite von kastenartigen oder fassartigen Leergutgebinden zur Verfügung zu stellen, welche eine Abtastung der Oberseite eines Leergutgebindes nicht beeinträchtigt und welche ein möglichst kleines Baumass aufweist.The invention has for its object to provide a device for scanning at least one side of box-like or barrel-like empties packages available, which does not interfere with a sampling of the top of an empties container and which has the smallest possible Baumass.

Die Erfindung und ihre VorteileThe invention and its advantages

Die erfindungsgemäße Vorrichtung mit den Merkmalen des Anspruchs 1 zeichnet sich dadurch aus, dass sie mit einer Lichtquelle oberhalb der Transporteinrichtung ausgestattet ist. Der Abstand der Lichtquelle zur Transporteinrichtung ist größer als die größte mögliche Höhe eines von der Vorrichtung zu erfassenden Leergutgebindes. Damit befindet sich die Lichtquelle auch oberhalb eines auf der Transporteinrichtung beförderten Leergutgebindes. Das Licht wird mittels eines seitlich und oberhalb der Transporteinrichtung verlaufenden Lichtleiters und mittels einer Abstrahleinrichtung nach unten in einen Bereich geleitet, in dem üblicherweise Kennzeichnungen an den Seiten eines Leergutgebindes angeordnet sind. Da die Lichtquelle oben und nicht seitlich angeordnet ist, weist die Vorrichtung ein kleines Baumass hinsichtlich ihrer Länge und ihrer Breite auf.The device according to the invention with the features of claim 1 is characterized in that it is equipped with a light source above the transport device. The distance of the light source to the transport device is greater than the largest possible height of an emptied container to be detected by the device. Thus, the light source is also above a conveyed on the transport container empties. The light is guided by means of a light guide extending laterally and above the transport device and by means of an emission device downwards into an area in which labels are usually arranged on the sides of an empties package. Since the light source is located above and not laterally, the device has a small amount of build-up in terms of its length and width.

Das Licht der Lichtquelle wird mittels einer Einrichtung aus dem Lichtleiter ausgekoppelt. Dieses Licht wird mittels der Abstrahleinrichtung auf die Seite eines Leergutgebindes gelenkt. Dadurch wird eine großflächige und homogene Beleuchtung der Seite eines Leergutgebindes mit vergleichsweise geringer Lichtintensität erreicht. Damit ist zum einen gewährleistet, dass eine Kennzeichnung an der Seite des Leergutgebindes nicht nur partiell sondern vollständig beleuchtet wird, und dass die Intensität der Beleuchtung so gering ist, dass sie eine parallel stattfindende Abtastung der Oberseite des Leergutgebindes nicht beeinträchtigt.The light from the light source is coupled out of the light guide by means of a device. This light is directed by means of the emission device on the side of a container empties. This will be a large-scale and homogeneous Lighting the side of an empties container achieved with comparatively low light intensity. This ensures, on the one hand, that a marking on the side of the empties package is not only partially but completely illuminated, and that the intensity of the illumination is so low that it does not affect parallel scanning of the top of the empties container.

Das von der Seite eines Leergutgebindes reflektierte Licht wird durch eine Kamera erfasst und anschließend ausgewertet. Zur Auswertung ist die Kamera mit einer Bildverarbeitungseinrichtung ausgestattet oder verbunden. Bei der Auswertung werden Informationen betreffend die auf der Seite des Leergutgebindes enthaltenen Erkennungsmerkmale, beispielsweise eine Kennzeichnung des Leergutgebindes, gewonnen.The reflected light from the side of an empties container is detected by a camera and then evaluated. For evaluation, the camera is equipped or connected with an image processing device. During the evaluation, information regarding the identification features contained on the side of the empties container, for example an identification of the empties container, is obtained.

Nach einer vorteilhaften Ausgestaltung der Erfindung ist die Einrichtung zum Auskoppeln mit einer Streuscheibe ausgestattet. Diese sorgt für ein diffuses Licht, welches besonders geeignet ist, um die Seite eines Leergutgebindes homogen zu beleuchten.According to an advantageous embodiment of the invention, the device for decoupling is equipped with a lens. This provides a diffused light, which is particularly suitable for homogeneously illuminating the side of an empties container.

Nach einer weiteren vorteilhaften Ausgestaltung weist die Abstrahleinrichtung eine Kammer mit mehreren das Licht der Lichtquelle diffus reflektierenden Oberflächen auf. Dabei kann es sich beispielsweise um matte, weiße Oberflächen handeln. Die die Rauheit der Oberfläche bedingenden Strukturen sind in diesem Fall größer als die Wellenlängen des Lichts der Lichtquelle. Bevorzugt wird weißes Licht des sichtbaren Wellenlängenbereichs eingesetzt. Der Lichtkegel des aus dem Lichtleiter ausgekoppelten Lichts wird in der Kammer aufgeweitet. Das aus dem Lichtleiter ausgekoppelte Licht trifft auf die Wände der Kammer und wird von diesen reflektiert. Durch eine seitlich an der Streuscheibe angeordnete Blende wird vermieden, dass das aus dem Lichtleiter ausgekoppelte Licht direkt auf ein Leergutgebinde fällt. Es findet damit keine direkte Beleuchtung, sondern eine indirekte Beleuchtung eines Leergutgebindes statt. Die Kammer ist nur an ihrer der Transporteinrichtung zugewandten Seite für das Licht der Lichtquelle durchlässig, so dass nur an dieser Seite das Licht die Kammer verlassen kann. Die Größe der Kammer wird dabei so gewählt, dass der aus der Kammer austretende Lichtkegel groß genug ist, um die Seite eines typischen Leergutgebindes möglichst vollständig zu beleuchten. Da die Kammer an der Seite oberhalb der Transporteinrichtung angeordnet ist, ist der Abstand zwischen einem Leergutgebinde und der Kammer und damit die Aufweitung des Lichtkegels nach dem Austritt aus der Kammer innerhalb gewisser Grenzen vorgegeben. Da der Abstand zwischen der Kammer und einem auf der Transporteinrichtung beförderten Leergutgebinde klein ist, wird der Lichtstrahl nach dem Austritt des Lichts aus der Kammer nur noch in geringem Umfang aufgeweitet.According to a further advantageous embodiment, the emission device has a chamber with a plurality of surfaces which diffusely reflect the light of the light source. These may be, for example, matt, white surfaces. The roughness of the surface conditional structures in this case are greater than the wavelengths of the light of the light source. Preferably, white light of the visible wavelength range is used. The light cone of the light coupled out of the light guide is widened in the chamber. The light coupled out of the light guide strikes the walls of the chamber and is reflected by them. By a laterally arranged on the lens aperture is avoided that the decoupled from the light guide light falls directly onto an empty container. There is thus no direct lighting, but an indirect lighting of an empties container instead. The chamber is facing only at its the transport device Page permeable to the light from the light source, so that only at this side the light can leave the chamber. The size of the chamber is chosen so that the emerging from the chamber light cone is large enough to illuminate the side of a typical empties container as completely as possible. Since the chamber is arranged on the side above the transport device, the distance between an empties container and the chamber and thus the expansion of the light cone after exiting the chamber is given within certain limits. Since the distance between the chamber and an emptied container conveyed on the transport device is small, the light beam is expanded only to a small extent after the exit of the light from the chamber.

Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung weist die Kammer eine senkrecht zur Transportoberfläche der Transporteinrichtung ausgerichtete, für das Licht der Lichtquelle durchlässige Scheibe auf. Diese deckt die Seite der Kammer ab, durch die das Licht in Richtung der Transporteinrichtung und eines auf der Transporteinrichtung beförderten Leergutgebindes abgestrahlt wird. Die Scheibe schließt sich unmittelbar an die Oberkante der Transportoberfläche der Transporteinrichtung an. Sie trennt damit die Kammer von der Transporteinrichtung und sorgt dafür, dass die Kammer vor Verunreinigungen geschützt wird. Durch die Scheibe wird das Licht aus der Kammer auf ein auf der Transporteinrichtung befördertes Leergutgebinde abgestrahlt.According to a further advantageous embodiment of the invention, the chamber has a perpendicular to the transport surface of the transport device, for the light of the light source permeable disk. This covers the side of the chamber through which the light is emitted in the direction of the transport device and an emptied container transported on the transport device. The disc connects directly to the upper edge of the transport surface of the transport device. It thus separates the chamber from the transport device and ensures that the chamber is protected from contamination. Through the disc, the light is emitted from the chamber to a transported on the transport device empties container.

Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung ist die Scheibe getönt. Sie besteht typischerweise aus Glas oder Kunststoff. Durch die Tönung wird die Lichttransmission reduziert. Ferner können bestimmte Wellenlängen des Lichts vollständig blockiert werden. Zur Tönung ist die Scheibe meist eingefärbt, beispielsweise in den Farben braun, blau, grün, rot oder gelb. Die Tönung sorgt dafür, dass die Lichtintensität des auf die Seite eines Leergutgebindes abgestrahlten Lichts zusätzlich reduziert wird und eine Beeinträchtigung der Abtastung der Oberseite eines Leergutgebindes ausgeschlossen wird.According to a further advantageous embodiment of the invention, the disc is tinted. It is typically made of glass or plastic. The tint reduces the light transmission. Furthermore, certain wavelengths of light can be completely blocked. For tinting the disc is usually colored, for example in the colors brown, blue, green, red or yellow. The tint ensures that the light intensity of the light emitted on the side of an empties container is additionally reduced and a Impairment of scanning the top of an empties container is excluded.

Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung ist die Kamera oberhalb der Kammer angeordnet. Dadurch kann das Baumass der Vorrichtung klein gehalten werden. Die Kamera befindet sich in diesem Fall zwischen der Kammer und der Lichtquelle. Darüber hinaus wird verhindert, dass das aus dem Lichtleiter ausgekoppelte Licht direkt in die Kamera fällt. Die Kammer weist eine Öffnung auf, durch die das von der Oberfläche eines Leergutgebindes reflektierte Licht in die Kamera einfallen kann.According to a further advantageous embodiment of the invention, the camera is arranged above the chamber. As a result, the construction dimension of the device can be kept small. The camera is in this case between the chamber and the light source. In addition, the light emitted from the light guide is prevented from falling directly into the camera. The chamber has an opening through which the light reflected from the surface of an empties package can enter the camera.

Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung ist sie mit einem Spiegel ausgestattet, um das von der Oberfläche eines Leergutgebindes reflektierte Licht in Richtung der Kamera umzulenken. Die Position und die Ausrichtung des Spiegels werden dabei an die Position der Kamera angepasst.According to a further advantageous embodiment of the invention, it is equipped with a mirror to redirect the light reflected from the surface of a container empties in the direction of the camera. The position and orientation of the mirror are adjusted to the position of the camera.

Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung ist die Vorrichtung an der der Transporteinrichtung zugewandten Seite mit einer Licht absorbierenden Oberfläche ausgestattet. Davon ausgenommen ist die Scheibe an der Kammer. Die absorbierende Oberfläche sorgt dafür, dass das Licht der Lichtquelle einer Vorrichtung zur Abtastung der Oberseite eines Leergutgebindes nicht durch Reflektionen in den Bereich seitlich eines Leergutgebindes gelangen kann, in welchem sich eine Kennzeichnung befindet. Dadurch wird verhindert, dass dieses Licht die Abtastung der Seite eines Leergutgebindes beeinträchtigt. Ferner sind die Kamera der Vorrichtung zur Abtastung einer Seite eines Leergutgebindes sowie ein Spiegel zum Umlenken des von der Oberfläche der Seite eines Leergutgebindes reflektierten Lichts derart angeordnet, dass ein unerwünschter direkter Lichteinfall von oben ausgeschlossen werden kann.According to a further advantageous embodiment of the invention, the device is equipped on the side facing the transport device with a light-absorbing surface. The exception is the disc on the chamber. The absorbing surface ensures that the light of the light source of a device for scanning the top of an empties container can not pass through reflections in the region of the side of an empties container in which a label is located. This prevents this light from affecting the scanning of the side of an empties container. Further, the camera of the device for scanning a side of a container empties and a mirror for deflecting the light reflected from the surface of the side of a container empties are arranged such that an undesirable direct light from above can be excluded.

Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung ist die Einrichtung zum Auskoppeln des Lichts aus dem Lichtleiter durch eine der Wände der Kammer gegen die Transporteinrichtung abgeschirmt. Dadurch wird verhindert, dass das aus dem Lichtleiter ausgekoppelte Licht direkt auf ein Leergutgebinde abgestrahlt wird, welches auf der Transporteinrichtung befördert wird. Außerdem wird vermieden, dass aus dem Lichtleiter ausgekoppeltes Licht durch Streuung und Reflektion nach oben abgestrahlt wird.According to a further advantageous embodiment of the invention, the means for coupling the light from the light guide by one of Walls of the chamber shielded against the transport device. This prevents that the light coupled out of the light guide is emitted directly onto an emptied container, which is conveyed on the transport device. In addition, it is avoided that coupled out of the light guide light is emitted by scattering and reflection upwards.

Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung ist die Lichtquelle Teil einer Vorrichtung zum Abtasten der Oberseite eines kastenartigen oder fassartigen Leergutgebindes. Damit kann die Lichtquelle für beide Vorrichtungen eingesetzt werden. Dadurch wird der Platzbedarf beider Vorrichtungen zusätzlich reduziert.According to a further advantageous embodiment of the invention, the light source is part of a device for scanning the top of a box-like or barrel-type empties container. Thus, the light source can be used for both devices. As a result, the space requirement of both devices is additionally reduced.

Weitere Vorteile und vorteilhaften Ausgestaltungen der Erfindung sind in der nachfolgenden Beschreibung, der Zeichnung und den Ansprüche enthalten.Further advantages and advantageous embodiments of the invention are contained in the following description, the drawing and the claims.

In the drawing, an embodiment of the invention is shown. It shows:
FIG. 1
Device in a view in the transport direction of the transport device.

Beschreibung des AusführungsbeispielsDescription of the embodiment

In Figur 1 sind eine Vorrichtung zur Erfassung von Erkennungsmerkmalen an mindestens einer Seite von kastenartigen oder fassartigen Leergutgebinden und eine Transporteinrichtung dargestellt. Die Blickrichtung in Figur 1 entspricht der Transportrichtung der Transporteinrichtung 1. Die Transporteinrichtung ist mit einem Transportband 2 ausgestattet, auf dem ein Leergutgebinde 3 in Form einer Getränkekiste befördert wird. Die Vorrichtung zur Erfassung von Erkennungsmerkmalen an mindestens einer Seite des Leergutgebindes 3 weist eine Lichtquelle 4, einen Lichtleiter 5 mit einer Streuscheibe 6 zum Auskoppeln des Lichts aus dem Lichtleiter, eine Kammer 7 mit diffus reflektierenden Oberflächen 8 an den Wänden, eine getönte Scheibe 9, einen Spiegel 10 und eine Kamera 11 auf. Die Teile der Vorrichtung sind mit Ausnahme der Scheibe 9 an der der Transporteinrichtung zugewandten Seite mit einer Verkleidung 12 versehen. Diese Verkleidung deckt insbesondere teilweise die Kammer 7 und die Kamera 11 nach außen ab. Die Verkleidung 12 ist an der der Vorrichtung abgewandten Außenseite mit einer das Licht des sichtbaren Wellenlängenbereichs absorbierenden Oberfläche 13 versehen. Licht, das von dem Leergutgebinde reflektiert wird und auf diese Oberfläche trifft, wird absorbiert.In FIG. 1 a device for detecting recognition features on at least one side of box-like or barrel-like empties containers and a transport device are shown. The line of sight in FIG. 1 corresponds to the transport direction of the transport device 1. The transport device is equipped with a conveyor belt 2, on which an empties container 3 is conveyed in the form of a crate. The device for detecting identification features on at least one side of the empties container 3 has a light source 4, a light guide 5 with a diffusing screen 6 for decoupling the light from the light guide, a chamber 7 with diffusely reflecting surfaces 8 on the walls, a tinted window 9, a mirror 10 and a camera 11. The parts of the device are provided with the exception of the disc 9 on the side facing the transport device with a panel 12. In particular, this panel partially covers the chamber 7 and the camera 11 to the outside. The cladding 12 is provided on the outer side facing away from the device with a surface 13 absorbing the light of the visible wavelength range. Light that is reflected by the empty container and hits this surface is absorbed.

Das Licht der Lichtquelle 4 wird in den Lichtleiter 5 eingekoppelt und seitlich senkrecht nach unten geführt. Die Lichtquelle 4 erzeugt weißes Licht im sichtbaren Bereich. Am unteren Ende des Lichtleiters 5 wird das Licht über eine Streuscheibe 6 ausgekoppelt. Von dort trifft das Licht auf die Wände der Kammer 7 und wird an den Oberflächen der Wände diffus gestreut bzw. reflektiert. Dabei entsteht gleichmäßiges, kontrast- und schattenarmes, weiches Licht, das für eine homogene Beleuchtung der Seite des Leergutgebindes 3 bestens geeignet ist. Das Licht wird durch die getönte Scheibe 9 auf das Leergutgebinde 3 abgestrahlt. Der Lichtleiter endet oberhalb der getönten Scheibe 9. Dadurch wird verhindert, dass das aus dem Lichtleiter 5 ausgekoppelte Licht direkt auf das Leergutgebinde abgestrahlt wird. Vielmehr wird es zunächst an den Oberflächen 8 der Wände der Kammer 7 diffus gestreut oder reflektiert. Das von der Seite 14 des Leergutgebindes 3 reflektierte Licht fällt durch die getönte Scheibe 9 zurück in die Kammer 7 und auf den Spiegel 10, der es in Richtung der Kamera 11 umlenkt. Dort wird die Information, die in dem von der Seite des Leergutgebindes 3 reflektierten Licht enthalten ist, erfasst und ausgewertet. Auf diese Weise können Kennzeichnungen wie Logos oder Marken auf der Seite des Leergutgebindes erkannt werden.The light of the light source 4 is coupled into the light guide 5 and guided laterally vertically downwards. The light source 4 generates white light in the visible range. At the lower end of the light guide 5, the light is coupled via a lens 6. From there, the light hits the walls of the chamber 7 and is diffused or reflected on the surfaces of the walls. The result is uniform, low-contrast and low-shadow, soft light, which is ideally suited for homogeneous illumination of the side of the empties container 3. The light is emitted through the tinted disc 9 on the empties container 3. The light guide ends above the tinted disc 9. This prevents that the light coupled out of the light guide 5 is emitted directly to the empties container. Rather, it is first scattered or reflected diffusely on the surfaces 8 of the walls of the chamber 7. The reflected light from the side 14 of the empties container 3 falls through the tinted disc 9 back into the chamber 7 and the mirror 10, which deflects it in the direction of the camera 11. There, the information contained in the reflected light from the side of the empties 3, recorded and evaluated. In this way, labels such as logos or brands can be recognized on the side of the empties container.

Das durch die getönte Scheibe 9 austretende diffuse Licht weist eine geringe Intensität auf. Da sich die getönte Scheibe ferner nahe des Transportbandes 2 befindet und sich nach oben die mit einer absorbierenden Oberfläche 13 versehene Verkleidung 12 anschließt, kann ausgeschlossen werden, dass Licht der Lichtquelle 4 nach oben in den Bereich oberhalb des Leergutgebindes reflektiert oder gestreut wird. Oberhalb des Leergutgebindes ist eine Vorrichtung 15 zur Erfassung der Oberseite eines Leergutgebindes angeordnet. Diese ist mit mindestens einer Lichtquelle und mindestens einer Kamera zur Aufnahme des von dem Leergutgebinde reflektierten Lichts ausgestattet. Lichtquelle und Kamera dieser Vorrichtung sind in der Zeichnung nicht dargestellt.The diffused light emerging through the tinted disk 9 has a low intensity. Since the tinted disc also near the conveyor belt 2 and adjoins the top 12 provided with an absorbent surface 13 panel 12, it can be ruled out that light from the light source 4 is reflected or scattered upwards in the area above the empties container. Above the empties container, a device 15 for detecting the top of an empties container is arranged. This is equipped with at least one light source and at least one camera for receiving the reflected light from the empties container. Light source and camera of this device are not shown in the drawing.

Dank des Aufbaus der Vorrichtung zur Erfassung von Erkennungsmerkmalen an mindestens einer Seite von kastenartigen oder fassartigen Leergutgebinden kann vermieden werden, dass Licht der Lichtquelle 4 zu der Kamera der Vorrichtung 15 zur Erfassung der Oberseite gelangt. Darüber hinaus kann verhindert werden, dass Licht der Lichtquellen der Vorrichtung 15 zur Erfassung der Oberseite über den Spiegel 10 in die Kamera 11 gelangt. Die beiden Vorrichtungen stören sich damit gegenseitig nicht.Thanks to the construction of the device for detecting recognition features on at least one side of box-like or barrel-like empties containers can be avoided that light from the light source 4 reaches the camera of the device 15 for detecting the top. In addition, it can be prevented that light of the light sources of the device 15 for detecting the top passes through the mirror 10 in the camera 11. The two devices do not interfere with each other.

In Figur 1 ist der Winkel α angegeben, unter dem das von der Seite des Leergutgebindes 3 reflektierte Licht über den Spiegel 10 gerade noch zu der Kamera 11 gelangt. Daraus ist erkennbar, dass die Position an der Seite des Leergutgebindes 3, von der aus Licht unter diesem Winkel reflektiert wird, nur wenig oberhalb der Mitte des Leergutgebindes liegt. Daraus ergibt sich, dass kein Licht einer Lichtquelle der Vorrichtung 15 direkt zu der Kamera 11 gelangen kann. Die getönte Scheibe 9 reduziert darüber hinaus die Möglichkeit oder Wahrscheinlichkeit, dass Streulicht anderer Lichtquellen durch die Kamera 11 erfasst und ausgewertet wird.In FIG. 1 the angle α is given, under which the light reflected from the side of the empties container 3 just passes through the mirror 10 to the camera 11. It can be seen that the position on the side of the empties container 3, from which light is reflected at this angle, is only slightly above the middle of the empties container. It follows that no light from a light source of the device 15 can reach the camera 11 directly. The tinted glass 9 also reduces the possibility or likelihood that stray light of other light sources is detected and evaluated by the camera 11.

In dem Ausführungsbeispiel gemäß Figur 1 ist die Vorrichtung zur Erfassung von Erkennungsmerkmalen an mindestens einer Seite von kastenartigen oder fassartigen Leergutgebinden nur auf der rechten Seite der Transporteinrichtung 1 angeordnet. Es besteht die Möglichkeit, eine entsprechende Vorrichtung alternativ oder kumulativ an der linken Seite der Transporteinrichtung anzuordnen. Ist an jeder Seite der Transporteinrichtung eine derartige Vorrichtung vorgesehen, können gleichzeitig auf zwei Seiten eines Leergutgebindes Erkennungsmerkmale erfasst werden.In the embodiment according to FIG. 1 For example, the device for detecting recognition features is arranged on at least one side of box-type or barrel-type empty packaging only on the right-hand side of the transport device 1. There is the possibility of a corresponding device alternatively or cumulatively to be arranged on the left side of the transport device. If such a device is provided on each side of the transport device, recognition features can be detected simultaneously on two sides of an empties container.

Sämtliche Merkmale der Erfindung können sowohl einzeln als auch in beliebiger Kombination miteinander erfindungswesentlich sein.All features of the invention may be essential to the invention both individually and in any combination with each other.
