Description
Die Erfindung geht aus von einem Verfahren und einer Vorrichtung zur Erfassung des Materials und des Füllzustands von Leergutbehältern in Leergut-Rücknahmeautomaten.The invention is based on a method and a device for detecting the material and the filling state of empties containers in reverse vending machines.
Leergut-Rücknahmeautomaten dienen dazu, einzelne Leergutbehälter, insbesondere Flaschen oder Dosen, aufzunehmen und in Abhängigkeit von charakteristischen Merkmalen der eingegebenen Leergutbehälter ein Pfand an den Benutzer auszugeben. Aus dem Stand der Technik sind Leergut-Rücknahmeautomaten bekannt, die einzelne Leergutbehälter in entweder horizontaler oder vertikaler Ausrichtung aufnehmen und in dieser Position anhand einer Erkennungseinrichtung die charakteristischen Merkmale der einzelnen Leergutbehälter ermitteln. Zu den charakteristischen Merkmalen zählen beispielsweise die Form, das Material, der Füllzustand bzw. Füllstand, ein Strichcode und eine DPG-Logoerkennung. Der Füllzustand oder Füllstand eines Leergutbehälters hängt davon ab, ob der Leergutbehälter vollständig entleert ist oder noch einen Inhalt aufweist. Ist ein Leergutbehälter ganz oder teilweise gefüllt, so wird er von dem Leergut-Rücknahmeautomaten zurückgewiesen und an den Kunden wieder ausgegeben. Das Material eines Leergutbehälters ist entscheidend für die weitere Ver- und Bearbeitung des Leergutbehälters im Leergut-Rücknahmeautomat. Die Leergutbehälter werden daher in Abhängigkeit ihres Materials unterschiedlichen weiteren Stationen zugeführt. Leegutbehälter aus Glas werden mehrfach verwendet und daher gesammelt. Bei einigen Leergutbehältern aus Kunststoff oder Metall handelt es sich um Einwegbehälter. Sie werden daher häufig gepresst oder zerkleinert.Empties reverse vending machines serve to receive individual empty containers, especially bottles or cans, and issue a deposit to the user depending on the characteristics of the entered empty containers. Empties reverse vending machines are known from the prior art record the individual empty containers in either horizontal or vertical orientation and determine the characteristic features of the individual empty containers in this position by means of a detection device. Characteristic features include, for example, the shape, the material, the filling state or filling level, a barcode and a DPG logo recognition. The fill level or fill level of an empties container depends on whether the empties container is completely emptied or still has a content. If an empty container is completely or partially filled, it will be rejected by the reverse vending machine and returned to the customer. The material of an empties container is crucial for the further processing and processing of the empties container in the reverse vending machine. The empties containers are therefore supplied to different other stations depending on their material. Leegutbehälter made of glass are used several times and therefore collected. Some plastic or metal empty containers are disposable containers. They are therefore often pressed or crushed.
Aus dem Stand der Technik beispielsweise der
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zur Erfassung des Materials und des Füllzustands von Leergutbehältern in Leergut-Rücknahmeautomaten zur Verfügung zu stellen, die die Feststellung des Materials und des Füllzustands der Leergutbehälter mit geringerem Aufwand ermöglichen, wobei die Vorrichtung kostengünstig herzustellen ist und nicht anfällig gegen Verschleiß ist.The invention has for its object to provide a method and apparatus for detecting the material and the filling state of empties containers in reverse vending machines are available that allow the determination of the material and the filling state of the empty containers with less effort, the device to produce cost is and is not prone to wear.
Die Aufgabe wird durch ein Verfahren mit den Merkmalen des Anspruchs 1 und eine Vorrichtung mit den Merkmalen des Anspruchs 9 gelöst. Das Verfahren zeichnet sich dadurch aus, dass lediglich geprüft wird, ob das Gewicht eines Leergutbehälters unterhalb eines vorgegebenen Gewichts-Schwellenwertes liegt, und ob bei Bestrahlung eines Leergutbehälters mit Licht eines bestimmten Wellenlängenbereichs eine Transmission des Lichts durch den Leergutbehälter feststellbar ist. Aus den Ergebnissen der Überprüfung der beiden Kriterien kann geschlossen werden, ob es sich um einen leeren oder gefüllten Leergutbehälter handelt, und ob der Leergutbehälter, sofern leer, aus Glas, Metall oder Kunststoff besteht. Weitere Kriterien müssen hierzu nicht untersucht werden. Zur Überprüfung ist die erfindungsgemäße Vorrichtung mit einem Drucksensor und einem Durchlichtsensor ausgestattet. Weitere Sensoren oder Detektoren sind nicht notwendig.The object is achieved by a method having the features of
Mit dem Drucksensor wird überprüft, ob der durch den Leergutbehälter auf den Drucksensor ausgeübte Druck, der von der Gewichtskraft des Leergutbehälters abhängt, kleiner als ein vorgegebener Schwellenwert ist. Dem Druck-Schwellenwert wird dabei der korrespondierende Gewichts-Schwellenwert zugeordnet. Liegt das Gewicht unterhalb des Schwellenwertes, wird angenommen, dass der Leergutbehälter leer ist und aus Metall oder Kunststoff besteht. Stimmt das Gewicht mit dem Schwellenwert überein oder ist größer als der Schwellenwert, so wird angenommen, dass der Leergutbehälter zumindest teilweise mit einem Inhalt gefüllt ist oder aus Glas besteht. Besteht der Behälter aus Glas, so kann er leer oder voll sein. Zur weiteren Unterscheidung dient das Ergebnis des Durchlichtsensors.With the pressure sensor, it is checked whether the pressure exerted by the empty container on the pressure sensor pressure, which depends on the weight of the empty container, is smaller than a predetermined threshold. The pressure threshold is the corresponding weight threshold assigned. If the weight is below the threshold, it is assumed that the empty container is empty and made of metal or plastic. If the weight coincides with the threshold or is greater than the threshold, it is assumed that the empty container is at least partially filled with a content or made of glass. If the container is made of glass, it can be empty or full. To further differentiate the result of the transillumination sensor is used.
Mit dem Durchlichtsensor wird die Transmission des Lichts durch den Leergutbehälter erfasst. Die Transmission und Absorption von Licht hängt vom Material ab. Jedes Material weist für bestimmte Wellenlängenbereiche eine spezifische Lichtabsorption und Lichttransmission auf. Jeder Leergutbehälter wird mittels einer Beleuchtungseinrichtung mit Licht eines bestimmten Wellenlängenbereichs bestrahlt. Der Durchlichtsensor erfasst das Licht nach dem Passieren des Leergutbehälters. Wird eine Transmission festgestellt, so wird davon ausgegangen, dass der Leergutbehälter leer ist und aus Glas oder durchsichtigem Kunststoff besteht. Wird keine Transmission oder nur geringe Transmission festgestellt, so wird davon ausgegangen, dass der Leergutbehälter aus Metall besteht und/ oder zumindest teilweise mit Inhalt gefüllt ist.The transmitted light sensor detects the transmission of light through the empty container. The transmission and absorption of light depends on the material. Each material has a specific light absorption and light transmission for specific wavelength ranges. Each empty container is irradiated by means of a lighting device with light of a certain wavelength range. The transmitted light sensor detects the light after passing through the empties container. If a transmission is detected, it is assumed that the empty container is empty and made of glass or transparent plastic. If no transmission or only low transmission is detected, then it is assumed that the empty container is made of metal and / or at least partially filled with content.
Aus der Kombination der beiden Abfragen ergibt sich eine eindeutige Zuordnung des Leergutbehälters in eine der vier Kategorien:
- teilweise mit Inhalt gefüllter Leergutbehälter aus Glas, Metall oder Kunststoff,
- leerer Leergutbehälter aus Metall,
- leerer Leergutbehälter aus Kunststoff,
- leerer Leergutbehälter aus Glas.
- partially filled with content empties container made of glass, metal or plastic,
- empty empty container made of metal,
- empty empty plastic container,
- empty empty glass container.
Nach einer vorteilhaften Ausgestaltung des erfindungsgemäßen Verfahrens wird überprüft, ob das Licht nach der Transmission durch einen Leergutbehälter unterhalb eines vorgegebenen Transmissions-Schwellenwerts liegt. Ist die Intensität des Lichts nach dem Passieren des Leergutbehälters kleiner als der Transmissions-Schwellenwert, wird davon ausgegangen, dass das Licht überwiegend von dem Leergutbehälter oder seinem Inhalt absorbiert oder reflektiert wird. Der Schwellenwert wird in Abhängigkeit von den typischen Materialien der Leergutbehälter festgelegt.According to an advantageous embodiment of the method according to the invention, it is checked whether the light after transmission through an empty container is below a predetermined transmission threshold. If the intensity of the light after passing through the empties container is less than the transmission threshold, it is assumed that the light is predominantly absorbed or reflected by the empty container or its contents. The threshold is determined depending on the typical materials of the empty containers.

Auf diese Weise kann besonders exakt von der Transmission des Lichts auf das Material des Leergutbehälters geschlossen werden.According to a further advantageous embodiment of the method according to the invention, the illumination device emits monochromatic light. In this way, the transmission of the light to the material of the empty container can be closed particularly accurately.
Nach einer weiteren vorteilhaften Ausgestaltung des erfindungsgemäßen Verfahrens werden die Leergutbehälter über eine Strecke mittels der Beleuchtungseinrichtung mit Licht bestrahlt, die im aufgerichteten Zustand des Leergutbehälters seiner Höhe oder einem Teil seiner Höhe entspricht. Ferner wird mittels des Durchlichtsensors die Transmission des Lichts auf einer entsprechenden Strecke untersucht. Auf diese Weise kann festgestellt werden, bis zu welcher Höhe der Leergutbehälter mit einem Inhalt, typischer Weise flüssiger Art, gefüllt ist.According to a further advantageous embodiment of the method according to the invention, the empty containers are irradiated over a distance by means of the illumination device with light that corresponds to its height or part of its height in the erected state of the empty container.

These may, for example, be light-emitting diodes. These are also suitable for generating a narrowband light.
Nach einer weiteren vorteilhaften Ausgestaltung der erfindungsgemäßen Vorrichtung weist der Durchlichtsensor mindestens einen Lichtsensor auf, der das von der Beleuchtungseinrichtung emittierte Licht nach der Transmission durch einen Leergutbehälter erfasst. Bei dem Lichtsensor kann es sich beispielsweise um eine CCD-Kamera oder um eine Fotodiode handeln. Die CCD-Kamera oder mehrere nebeneinander angeordnete Fotodioden gestatten eine ortsaufgelöste Auswertung des auszuwertenden Lichtes. Dabei ist zu beachten, dass die Messung nicht durch Streulicht oder Licht sonstiger Quellen verfälscht wird.According to a further advantageous embodiment of the device according to the invention, the transmitted light sensor has at least one light sensor, which detects the light emitted by the illumination device after transmission through an empty container. The light sensor may be, for example, a CCD camera or a photodiode. The CCD camera or several adjacently arranged photodiodes allow a spatially resolved evaluation of the light to be evaluated. It is too Note that the measurement is not distorted by stray light or light from other sources.
Nach einer weiteren vorteilhaften Ausgestaltung der erfindungsgemäßen Vorrichtung ist diese mit einem Transportband ausgestattet, um die Leergutbehälter in vertikaler Ausrichtung aufzunehmen und zu dem Drucksensor und dem Durchlichtsensor zu transportieren. Das Transportband kann dabei Teil einer Transporteinrichtung eines Leergutrücknahmeautomaten sein mit dem die erfindungsgemäße Vorrichtung ausgestattet ist.According to a further advantageous embodiment of the device according to the invention this is equipped with a conveyor belt to receive the empties container in a vertical orientation and to transport to the pressure sensor and the transmitted light sensor. The conveyor belt can be part of a transport device of a reverse vending machine with which the device according to the invention is equipped.
Nach einer weiteren vorteilhaften Ausgestaltung der erfindungsgemäßen Vorrichtung sind die Beleuchtungseinrichtung und der Durchlichtsensor seitlich am Transportband angeordnet. Dabei befindet sich die Beleuchtungseinrichtung an der einen Seite und der Durchlichtsensor an der gegenüberliegenden Seite des Transportbandes. In diesem Fall kann die Überprüfung der Transmission während des Transportes des Leergutbehälters stattfinden.According to a further advantageous embodiment of the device according to the invention, the illumination device and the transmitted light sensor are arranged laterally on the conveyor belt. In this case, the illumination device is located on one side and the transmitted light sensor on the opposite side of the conveyor belt. In this case, the verification of the transmission can take place during the transport of the empties container.
Nach einer weiteren vorteilhaften Ausgestaltung der erfindungsgemäßen Vorrichtung ist der Drucksensor unmittelbar unterhalb des Transportbandes angeordnet. Die Überprüfung des durch den Leergutbehälter auf den Drucksensor ausgeübten Drucks kann dabei während des Transportes des Leergutbehälters auf dem Transportband stattfinden. Der Vorgang der Überprüfung des Materials und des Füllzustandes des Leergutbehälters wird damit in den Transportvorgang integriert. Die Überprüfung kann im Durchlauf erfolgen, was zu einer Beschleunigung des Verfahrens führt.According to a further advantageous embodiment of the device according to the invention, the pressure sensor is arranged directly below the conveyor belt. The verification of the pressure exerted by the empty container on the pressure sensor pressure can take place during the transport of the empty container on the conveyor belt. The process of checking the material and the filling state of the empty container is thus integrated into the transport process. The check can be carried out in one pass, which leads to an acceleration of the procedure.
