Description

Die Erfindung betrifft ein Pfandrücknahmesystem, das eine Entwertungseinheit zum irreversiblen Zerstören von eingegebenen Einweggut umfasst. Ferner betrifft die Erfindung ein Verfahren zur Überwachung eines solchen Pfandrücknahmesystems.The invention relates to a deposit collection system comprising a devaluation unit for irreversibly destroying input disposable goods. Furthermore, the invention relates to a method for monitoring such a deposit-return system.

Bekannte Pfandrücknahmesysteme, die häufig auch als revers wending machines bezeichnet werden, umfassen eine Fronteinheit, in die das Einweggut eingegeben wird. Anschließend wird das Einweggut über eine Sortierstrecke zu einem Kompaktor transportiert, in dem das Einweggut über eine Entwertungseinheit zum irreversiblen Zerstören des eingegebenen Einweggutes und zum Verkleinern des Volumens des Einweggutes vorgesehen ist, kompaktiert wird bevor das Einweggut dann in einem Behälter gesammelt wird. Der Person, die das Einweggut eingegeben hat, wird entsprechend der Pfandbetrag gutgeschrieben.Known deposit return systems, which are often referred to as reverse wending machines, include a front unit into which the disposable material is entered. Subsequently, the disposable material is transported via a sorting line to a Kompaktor in which the disposable material is provided via a devaluation unit for irreversible destruction of the input disposable material and to reduce the volume of the disposable material is compacted before the disposable material is then collected in a container. The person who has entered the disposable good will be credited according to the deposit amount.

Das Dokument DE 10 2010 036923 A1 offenbart eine Anordnung zur Rücknahme von Leergutbehältern, die eine Erkennungseinrichtung zur Identifikation des mit einem charakteristischen Merkmal versehenen Leergutbehälters umfasst.The document DE 10 2010 036923 A1 discloses an arrangement for taking back empties containers, which comprises a recognition device for identifying the empties container provided with a characteristic feature.

Aus dem Dokument KR 2009 0126107 A ist ein Pfandrücknahmerücknahmesystem bekannt, bei dem in der Nähe einer Entwertungseinheit ein Mikrofon angeordnet ist, mit dessen Hilfe die beim Auftreffen von Einweggütern auf das Entwertungssystem entstehenden Geräusche aufgenommen werden. Hierbei werden spezielle Frequenzen ermittelt, die dann mit hinterlegten typischen Frequenzen der beim Auftreffen des Einwegguts auf die Entwertungseinheit entstehenden Geräuschen verglichen werden. Mit Hilfe dieses Vergleichs sollen insbesondere Fehlfunktionen erkannt werden.From the document KR 2009 0126107 A a deposit return withdrawal system is known in which a microphone is arranged in the vicinity of a devaluation unit, with the aid of which the noise generated when hitting disposable goods on the cancellation system are recorded. In this case, specific frequencies are determined, which are then compared with stored typical frequencies of the noise generated when the disposable goods hit the invalidation unit. With the help of this comparison in particular malfunctions should be recognized.

Es sind Betrugsversuche bekannt, bei denen das Einweggut innerhalb der Sortierstrecke zwischen der Fronteinheit und dem Kompaktor abgefangen und erneut der Fronteinheit zugeführt wird, was dazu führt, dass das Pfand des Einweggutes mehrfach gutgeschrieben wird, da die Erfassung und Gutschreibung bereits über die Fronteinheit erfolgt.Fraud attempts are known in which the disposable material is intercepted within the sorting path between the front unit and the Kompaktor and fed again to the front unit, which leads to the pledge of the disposable good is credited multiple times, since the detection and credit is already on the front unit.

Zur Vermeidung solcher Betrugsversuche ist es bekannt, dass an der Sortierstrecke Sensoren vorgesehen sind, die ein Entnehmen von Einweggut aus der Sortierstrecke erkennen sollen. Allerdings gibt es auch Betrugsversuche, bei denen diese Sensoren manipuliert oder umgangen werden.To avoid fraud attempts, it is known that sensors are provided on the sorting path, which are intended to detect a removal of disposable material from the sorting path. However, there are also fraud attempts in which these sensors are manipulated or bypassed.

Es ist Aufgabe der Erfindung, ein Pfandrücknahmesystem und ein Verfahren zur Überwachung eines Pfandrücknahmesystems anzugeben, mit dem Betrugsversuche über das mehrfache Zuführen des gleichen Einweggutes verhindert oder zumindest erschwert werden.It is an object of the invention to provide a deposit collection system and a method for monitoring a deposit recovery system, are prevented or at least made more difficult fraud attempts on the multiple supply of the same disposable goods.

Diese Aufgabe wird durch ein Pfandrücknahmesystem mit den Merkmalen des Anspruchs 1 und durch ein Verfahren mit den Merkmalen des unabhängigen Verfahrensanspruchs gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.This object is achieved by a deposit collection system having the features of claim 1 and by a method having the features of the independent method claim. Advantageous developments of the invention are specified in the dependent claims.

Erfindungsgemäß ist eine Schallerfassungseinheit zum Detektieren des beim Zerstören des Einweggutes durch die Entwertungseinheit entstehenden Schalls vorgesehen. In einem Speicherelement ist mindestens ein Sollwert mindestens einer charakteristischen Größe des beim Zerstören des Einweggutes entstehenden Schalls gespeichert. Eine Steuereinheit vergleicht diesen gespeicherten Sollwert mit mindestens einen über die Schallerfassungseinheit ermittelten Istwert dieser charakteristischen Größe des über die Schallerfassungseinheit detektierten Schalls.According to the invention, a sound detection unit is provided for detecting the sound produced when the disposable good is destroyed by the cancellation unit. In a memory element at least one setpoint value of at least one characteristic size of the sound produced when destroying the disposable good is stored. A control unit compares this stored setpoint value with at least one actual value of this characteristic variable of the sound detected via the sound detection unit via the sound detection unit.

Beim Zerstören des Einweggutes durch die Entwertungseinheit und dem hiermit verbundenen Zerstören der für die Erfassung des Einweggutes auf dem Einweggut vorgesehenen Merkmale entsteht ein charakteristischer Schall der über die charakteristischen Größen und deren Sollwerte in dem Speicherelement vorgegeben ist. Durch die Schallerfassungseinheit in der Nähe der Entwertungseinheit und dem Vergleich der ermittelten Werte mit den gespeicherten Sollwerten kann sichergestellt werden, dass das eingegebene Einweggut auch tatsächlich irreversibel zerstört wird. Somit können Betrugsversuche einfach erkannt werden.When destroying the disposable material by the devaluation unit and the associated destroying the provided for the detection of the disposable goods on the disposable goods features a characteristic sound is given on the characteristic variables and their setpoints in the memory element. By the sound detection unit in the vicinity of the devaluation unit and the comparison of the determined values with the stored setpoint values, it is possible to ensure that the input disposable material is actually irreversibly destroyed. Thus, fraud can be easily detected.

Bei einer besonders bevorzugten Ausführungsform der Erfindung ist in dem Speicherelement mindestens ein weiterer Sollwert einer weiteren charakteristischen Größe des Schalls gespeichert, wobei die Steuereinheit auch diesen Sollwert mit mindestens einem mit Hilfe der Schallerfassung ermittelten Istwert dieser weiteren charakteristischen Größe des detektierten Schalls vergleicht. Durch den Vergleich mehrerer charakteristischen Größen des Schalls kann eine noch genauere und sichere Erfassung erfolgen, sodass Fehler bei der Zuordnung des abgegebenen Schalls zu Einweggüter vermieden werden und Manipulationsversuchen noch sicherer vorgebeugt wird.In a particularly preferred embodiment of the invention, at least one further desired value of a further characteristic variable of the sound is stored in the memory element, the control unit also comparing this desired value with at least one actual value of this further characteristic variable of the detected sound determined with the aid of the sound detection. By comparing a plurality of characteristic quantities of the sound, an even more accurate and reliable detection can take place, so that errors in the allocation of the emitted sound to disposable goods are avoided and tampering attempts are even more reliably prevented.

Bei diesen charakteristischen Größen handelt es sich insbesondere um die Amplitude und/oder die Frequenzgänge des Schalls. Diese Größen können einfach erfasst werden und bilden eine sichere Erkennung der jeweiligen Einweggüter ab.These characteristic quantities are, in particular, the amplitude and / or the frequency responses of the sound. These sizes can be easily captured and form a reliable detection of the respective disposable goods.

Die Sollwerte für die charakteristischen Größen, die im Speicherelement gespeichert sind, wurden insbesondere vorab experimentell ermittelt.The setpoint values for the characteristic quantities stored in the memory element have been determined experimentally in advance in particular.

Besonders vorteilhaft ist es, wenn für verschiedene Einweggutarten unterschiedliche Sollwerte der charakteristischen Größe bzw. der charakteristischen Größen im Speicherelement gespeichert sind und wenn die Steuereinheit den Sollwert der Einweggutart des jeweils dem Pfandrücknahmesystem zugefügten Einweggutes auswählt und mit dem über die Schallerfassungseinheit ermittelten Istwert vergleicht. Somit wird sichergestellt, dass auch bei unterschiedlichen Einweggutarten, die dem Pfandrücknahmesystem zugeführt werden können, jeweils eine sichere Erkennung von deren Zerstörung erfolgen kann. Dies ist insbesondere dann wichtig, wenn verschiedene Einweggutarten mit einem unterschiedlich hohen Pfandbetrag versehen sind, sodass auch ein Austausch eines höherwertigen Einweggutes durch ein minderwertiges innerhalb der Sortierstrecke erkannt werden kann und somit auch ein Betrugsversuch über das Gutschreiben eines höheren Pfandbetrags als den zugeführten Einweggut vermieden wird.It is particularly advantageous if different setpoint values of the characteristic variable or of the characteristic variables are stored in the memory element for different types of disposable goods and if the control unit selects the setpoint value of the disposable material of the disposable material added to the deposit return system and compares it with the actual value determined via the sound acquisition unit. This ensures that even with different disposable goods that can be fed to the deposit recovery system, each reliable detection of their destruction can be done. This is particularly important when different disposable types of goods are provided with a different amount of deposit, so that an exchange of a higher-quality disposable goods can be detected by an inferior within the sorting line and thus a fraud attempt on the credit of a higher deposit amount than the supplied disposable material is avoided ,

Die Einweggutarten können beispielsweise PET-Flaschen, Dosen oder Glasflaschen sein.The disposable product types may be, for example, PET bottles, cans or glass bottles.

Es ist besonders vorteilhaft, wenn das Pfandrücknahmesystem eine im Sensor zur Erkennung des eingegebenen Einweggutes umfasst. Durch diesen Sensor erkennt das System, welche Einweggutarten eingegeben wurde, sodass die Steuereinheit den entsprechenden Sollwert aus dem Speicherelement verwenden kann.It is particularly advantageous if the deposit-return system includes a sensor for detecting the input disposable good. Through this sensor, the system detects which disposable items have been entered so that the controller can use the appropriate setpoint from the storage element.

Bei dem Sensor handelt es sich insbesondere um den gleichen Sensor, mit dem das Einweggut standardmäßig bei Pfandrücknahmesystemen bei seiner Eingabe erkannt wird. Insbesondere kann es sich um einen Barcodeleser handeln, der den auf den Einweggut aufgebrachten Strichcode für die Entpfandung ausliest.The sensor is, in particular, the same sensor with which the disposable material is recognized by default in the case of deposit-return systems as it is being input. In particular, it may be a barcode reader which reads the barcode applied to the disposable item for removal.

Das Pfandrücknahmesystem umfasst insbesondere eine Fronteinheit und einen separaten Kompaktor, in dem die Entwertungseinheit angeordnet ist. Die Fronteinheit und der Kompaktor sind insbesondere über eine Sortierstrecke miteinander verbunden, wobei der Sensor zur Erkennung des eingegebenen Einweggutes insbesondere in der Fronteinheit angeordnet ist.The deposit-return system comprises in particular a front unit and a separate Kompaktor in which the devaluation unit is arranged. The front unit and the Kompaktor are connected to each other in particular via a sorting path, wherein the sensor is arranged for detecting the input disposable good in particular in the front unit.

In dem Kompaktor ist insbesondere ein Schneidwerk angeordnet, über das das eingegebene Einweggut zerschnitten und/oder zusammengedrückt wird. Ferner ist in dem Kompaktor insbesondere ein Container vorgesehen, über den das kompaktierte und entwertete Einweggut gesammelt wird.In particular, a cutting unit is arranged in the compactor, via which the input disposable material is cut and / or compressed. Furthermore, in the compactor in particular a container is provided, via which the compacted and depreciated disposable material is collected.

Bei einer besonders bevorzugten Ausführungsform der Erfindung umfasst die Schallerfassungseinheit ein Mikrofon, mit dessen Hilfe der beim Zerstören der eingegebenen Einweggüter entstehende Schall erfasst wird. Dieses Mikrofon ist insbesondere in der Nähe der Entwertungseinheit, insbesondere in der Nähe eines Schneidewerkes angeordnet, sodass die entstehenden Geräusche sicher und ohne Einfluss von Umweltgrößen erfasst werden können.In a particularly preferred embodiment of the invention, the sound detection unit comprises a microphone, by means of which the sound produced when destroying the input disposable goods is detected. This microphone is arranged in particular in the vicinity of the cancellation unit, in particular in the vicinity of a cutting work, so that the resulting noise can be detected safely and without the influence of environmental factors.

Besonders vorteilhaft ist es, wenn das Mikrofon als Schall die bei der Zerstörung des Einweggutes entstehenden hörbaren Geräusche erfasst, d. h., dass das Mikrofon im für den Menschen hörbaren Bereich arbeitet. Alternativ oder zusätzlich kann das Mikrofon auch im nicht menschlich hörbaren Bereich, insbesondere im Ultraschallbereich, arbeiten. Somit wird eine besonders sichere Erfassung des Schalls und ein zuverlässiger Vergleich erreicht.It is particularly advantageous if the microphone detects as sound the audible noise resulting from the destruction of the disposable material, ie. That is, the microphone works in the human audible range. Alternatively or additionally, the microphone can also work in the non-human audible range, in particular in the ultrasound range. Thus, a particularly secure detection of the sound and a reliable comparison is achieved.

Als für den menschlichen Sinn hörbarer Schall wird insbesondere Schall zwischen 16 Hz und 20 kHz verstanden. Als Ultraschallbild wird insbesondere Schall zwischen 20 kHz und 1,6 GHz verstanden.In particular, sound between 16 Hz and 20 kHz is understood to mean sound audible to the human senses. In particular, sound between 20 kHz and 1.6 GHz is understood as ultrasound image.

Zusätzlich oder alternativ zu dem Mikrofon kann die Schallerfassungseinheit auch einen Körperschallabnehmer zum Erfassen von während der Zerstörung des Einweggutes entstehendem Körperschall umfassen. Auch über diesen Körperschallabnehmer, der insbesondere im Ultraschallbereich arbeitet, kann eine sichere Erkennung der Zerstörung des eingegebenen Einweggutes erreicht werden. Der Körperschallabnehmer erfasst insbesondere den Körperschall mindestens eines Bauteils des Pfandrücknahmesystems, beispielsweise eines Gehäuses des Pfandrücknahmesystems, insbesondere des Kompaktors, der Entwertungseinheit und/oder andere Bauteile in der Nähe der Entwertungseinheit, und/oder den Körperschall der Einweggüter.In addition or as an alternative to the microphone, the sound detection unit may also include a structure-borne sound pickup for detecting structure-borne noise arising during the destruction of the disposable material. Also via this structure-borne sound receiver, which operates in particular in the ultrasonic range, can reliably detect the destruction of the entered Disposable good can be achieved. In particular, the structure-borne sound pick-up detects the structure-borne noise of at least one component of the deposit collection system, for example a housing of the deposit return system, in particular of the compactor, the validation unit and / or other components in the vicinity of the validation unit, and / or the structure-borne noise of the disposable goods.

Die Steuereinheit nimmt das Pfandrücknahmesystem außer Betrieb, wenn der Vergleich mindestens eines Istwerts mit dem zugehörigen Sollwert eine Abweichung ergeben hat. Hierdurch wird erreicht, dass der Betrugsversuch verhindert wird. Insbesondere kann das System nur von einer autorisierten Person wieder aktiviert werden, sodass eine Aktivierung ohne Kenntnisnahme von dem Betrugsversuch vermieden wird.The control unit deactivates the deposit-return system if the comparison of at least one actual value with the associated nominal value has revealed a deviation. This ensures that the fraud attempt is prevented. In particular, the system can only be reactivated by an authorized person so that activation is avoided without notice of the attempted fraud.

Unter einer Abweichung des Sollwerts wird insbesondere verstanden, dass der Istwert um einen vorbestimmten Mindestprozentsatz oder Mindestabsolutwert von Sollwert. Durch die Verwendung solcher Toleranzgrenzen wird erreicht, dass das System nicht bereits bei minimalen, vermutlich nicht auf einem Betrugsversuch zurückführenden Abweichungen einen Betrugsversuch annimmt und unnötig außer Betrieb genommen wird bzw. die im Folgenden noch beschriebenen Konsequenzen durchgeführt werden.A deviation of the setpoint value is understood in particular to mean that the actual value is a predetermined minimum percentage or minimum absolute value of setpoint value. The use of such tolerance limits ensures that the system does not attempt to commit fraud even if the deviations are minimal, presumably not attributable to a fraud attempt, and that it is unnecessarily shut down or that the consequences described below are carried out.

Zusätzlich oder alternativ zur Außerbetriebnahme gibt die Steuereinheit beim Vorliegen einer relevanten Abweichung zwischen dem Ist- und dem Sollwert auch eine Fehlermeldung aus. Die Fehlermeldung kann insbesondere über eine Kommunikationseinheit des Pfandrücknahmesystems durch eine zentrale Überwachungseinheit erfolgen, sodass der Betrugsversuch einfach erkannt und protokolliert werden kann. Diese zentrale Überwachungseinheit umfasst insbesondere einen Zentralcomputer der das Pfandrücknahmesystem herstellenden und/oder betreibenden Firma.In addition or as an alternative to decommissioning, the control unit outputs in the presence of a relevant deviation between the actual and the setpoint also an error message. The error message can be made in particular via a communication unit of the deposit return system by a central monitoring unit, so that the fraud attempt can be easily detected and logged. This central monitoring unit comprises, in particular, a central computer of the company producing and / or operating the deposit-return system.

Darüber hinaus kann das Pfandrücknahmesystem auch eine Anzeigeeinheit, beispielsweise einen Bildschirm, umfassen, über den die Fehlermeldung zusätzlich oder alternativ angezeigt wird.In addition, the deposit-return system can also include a display unit, for example a screen, via which the error message is additionally or alternatively displayed.

Darüber hinaus wird beim Vorliegen einer Abweichung und somit eines vermuteten Betrugsversuches insbesondere der Pfandwert des eingegebenen Einweggutes nichts gutgeschrieben.In addition, in the event of a deviation and thus a suspected fraud attempt in particular the deposit value of the entered disposable good nothing credited.

Darüber hinaus kann das Pfandrücknahmesystem eine Alarmeinheit umfassen, die einen akustischen und/oder optischen Alarm ausgibt, sofern die Steuereinheit eine Abweichung zwischen mindestens einem Istwert und dem zugehörigen Sollwert detektiert hat. Insbesondere kann ein lauter Warnton ausgegeben werden und es kann ein Blinklicht aktiviert werden.In addition, the deposit-return system may include an alarm unit that outputs an audible and / or visual alarm, if the control unit has detected a deviation between at least one actual value and the associated setpoint. In particular, a loud warning sound can be output and a flashing light can be activated.

Hierdurch wird erreicht, dass andere Personen auf den Betrugsversuch aufmerksam gemacht werden, was eine abschreckende Wirkung ausübt.This ensures that others are made aware of the fraud attempt, which has a deterrent effect.

Ein weiterer Aspekt der Erfindung betrifft ein Verfahren zur Überwachung eines Pfandrücknahmesystems, bei dem in einem Speicherelement mindestens ein Sollwert mindestens einer charakteristischen Größe des beim Zerstören von Einweggut durch eine Entwertungseinheit zum irreversiblen Zerstören von eingegebenen Einweggut entstehenden Schalls gespeichert wird. Mit Hilfe einer Schallerfassungseinheit wird der beim Zerstören des Einweggutes durch die Entwertungseinheit entstehenden Schall erfasst. Anschließend wird mindestens ein mit Hilfe der Schallerfassungseinheit ermittelte Istwert dieser charakteristischen Größe des detektierten Schalls mit dem gespeicherten Sollwert verglichen.A further aspect of the invention relates to a method for monitoring a deposit-return system, in which at least one desired value of at least one characteristic variable of the sound resulting from the destruction of disposable material by a devaluation unit for irreversibly destroying input disposable goods is stored in a storage element. By means of a sound detection unit, the sound produced by the destruction unit when destroying the disposable material is detected. Subsequently, at least one actual value of this characteristic quantity of the detected sound determined with the aid of the sound detection unit is compared with the stored desired value.

Die Steuereinheit nimmt das Pfandrücknahmesystem außer Betrieb, wenn der Vergleich mindestens eines Istwerts mit dem zugehörigen Sollwert eine Abweichung ergeben hat. Hierdurch wird erreicht, dass der Betrugsversuch verhindert wird. Insbesondere kann das System nur von einer autorisierten Person wieder aktiviert werden, sodass eine Aktivierung ohne Kenntnisnahme von dem Betrugsversuch vermieden wird.The control unit deactivates the deposit-return system if the comparison of at least one actual value with the associated nominal value has revealed a deviation. This ensures that the fraud attempt is prevented. In particular, the system can only be reactivated by an authorized person so that activation is avoided without notice of the attempted fraud.

Zusätzlich oder alternativ zur Außerbetriebnahme gibt die Steuereinheit beim Vorliegen einer relevanten Abweichung zwischen dem Ist- und dem Sollwert auch eine Fehlermeldung aus. Die Fehlermeldung kann insbesondere über eine Kommunikationseinheit des Pfandrücknahmesystems durch eine zentrale Überwachungseinheit erfolgen, sodass der Betrugsversuch einfach erkannt und protokolliert werden kann. Diese zentrale Überwachungseinheit umfasst insbesondere einen Zentralcomputer der das Pfandrücknahmesystem herstellenden und/oder betreibenden Firma.In addition or as an alternative to decommissioning, the control unit also gives an error message if a relevant deviation between the actual value and the nominal value exists out. The error message can be made in particular via a communication unit of the deposit return system by a central monitoring unit, so that the fraud attempt can be easily detected and logged. This central monitoring unit comprises, in particular, a central computer of the company producing and / or operating the deposit-return system.

Hierdurch wird erreicht, dass Manipulationsversuche einfach erkannt werden können.This ensures that manipulation attempts can be easily detected.

Das Verfahren gemäß des unabhängigen Verfahrensanspruchs kann mit den in den abhängigen Vorrichtungsansprüchen angegebenen Merkmalen bzw. entsprechenden Verfahrensmerkmalen weiterbildet werden.The method according to the independent method claim can be further developed with the features indicated in the dependent device claims or corresponding method features.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der folgenden Beschreibung, die die Erfindung anhand von Ausführungsbeispielen im Zusammenhang mit der beigefügten Figur näher erläutert.Further features and advantages of the invention will become apparent from the following description, which illustrates the invention of embodiments in conjunction with the accompanying figure explained in more detail.

Es zeigt:

Figur 1
eine schematische Darstellung eines Pfandrücknahmesystems.
It shows:
FIG. 1
a schematic representation of a deposit return system.

In Figur 1 ist eine schematische, perspektivische Darstellung eines Pfandsystems 10 zur Rücknahme und Entpfandung von Einweggut gezeigt.In FIG. 1 is a schematic, perspective view of a deposit system 10 for taking back and Entpfandung disposable goods shown.

Das Pfandrücknahmesystem 10 umfasst eine Fronteinheit 12, die eine Eingabeöffnung 14 zur Eingabe von Einweggut 18 umfasst. Bei dem Einweggut 18 kann es sich insbesondere um Plastikflaschen und Dosen handeln.The deposit-return system 10 includes a front unit 12 that includes an input port 14 for inputting disposable goods 18. The disposable item 18 may be, in particular, plastic bottles and cans.

An dem Einweggut 18 ist ein Erkennungsmerkmal, beispielsweise ein Strichcode vorgesehen, der nach der Eingabe des Einweggutes 18 über eine Sensoreinheit 16 erkannt wird. Mit Hilfe der Sensoreinheit 16 wird ermittelt, ob das eingegebene Einweggut zurückgenommen werden soll, um welche Einweggutart es sich handelt und wie hoch der gutzuschreibende Pfandbetrag ist.On the disposable 18 an identification feature, such as a bar code is provided, which is detected by the input of the disposable material 18 via a sensor unit 16. With the help of the sensor unit 16 it is determined whether the input disposable goods should be withdrawn, what kind of disposable goods it is and how high is the amount to be credited deposit.

Ferner umfasst das Pfandrücknahmesystem 10 einen von der Fronteinheit 12 separat angeordneten Kompaktor 20, in dem eine Entwertungseinheit 22 vorgesehen ist, mit deren Hilfe das eingegebene Einweggut 18 irreversibel zerstört wird. Hierbei wird insbesondere das Volumen des Einweggutes über ein Schneidwerk reduziert und gleichzeitig werden die Sicherheitsmerkmale zerstört, über die die bepfandeten Einweggüter 18 von der Sensoreinheit 16 erkannt werden. Somit können die Einweggüter 18 nach dem Durchlaufen durch den Kompaktor 20 nicht erneut der Fronteinheit 12 zugeführt werden.Furthermore, the deposit-return system 10 comprises a compactor 20 arranged separately from the front unit 12, in which a devaluation unit 22 is provided with the aid of which the input disposable item 18 is irreversibly destroyed. In this case, in particular the volume of the disposable material is reduced via a cutting unit and at the same time the security features are destroyed, via which the deposit disposable goods 18 are detected by the sensor unit 16. Thus, the disposable goods 18 after passing through the compactor 20 can not be fed to the front unit 12 again.

Die kompaktierten Einweggüter 18 werden in einem Behälter 24 gespeichert, der regelmäßig entleert wird.The compacted disposable goods 18 are stored in a container 24 which is emptied regularly.

Das über die Fronteinheit 12 eingegebene Einweggut 18 wird über eine Sortierstrecke 26 zu dem Kompaktor 20 transportiert. Um Betrugsversuche zu unterbinden, bei denen das Einweggut 18 innerhalb dieser Sortierstrecke 26 entnommen und der Fronteinheit 12 erneut zugeführt wird, ist in dem Kompaktor 20 eine Schallerfassungseinheit 28 in der Nähe der Entwertungseinheit 22 vorgesehen, mit deren Hilfe der beim Zerstören des Einweggutes 18 erzeugte Schall aufgezeichnet wird.The input via the front unit 12 Einweggut 18 is transported via a sorting line 26 to the Kompaktor 20. In order to prevent attempts to cheat, in which the disposable 18 taken within this sorting line 26 and the front unit 12 is supplied again, a sound detection unit 28 is provided in the vicinity of the devaluation unit 22 in the Kompaktor 20, with the help of the sound generated when destroying the disposable material 18 is recorded.

In Abhängigkeit von der Einweggutart, also insbesondere in Abhängigkeit der Form, der Größe und des Materials des Einweggutes 18, ergeben sich für jede Einweggutart unterschiedliche typische Frequenzgänge und Amplituden des beim Zerstören entstehenden Schalls. Diese jeweiligen typischen Frequenzgänge und Amplituden sind für jede Einweggutart spezifisch, sodass sich über die beim Zerstören entstehenden Schall erkennen lässt, ob das der Fronteinheit 12 zugefügte Einweggut 18 auch tatsächlich zerstört wurde.Depending on the Einweggutart, ie in particular depending on the shape, the size and the material of the disposable material 18, arise for each disposable product different typical frequency responses and amplitudes of the Destroying emerging sound. These respective typical frequency responses and amplitudes are specific to each disposable product type so that it can be seen from the sound produced during destruction whether the disposable product 18 added to the front unit 12 has actually been destroyed.

Hierzu ist in einem Speicherelement 32 eine Datenbank hinterlegt, für die für jede Einweggutart Sollwerte der Amplituden und typischen Frequenzgänge hinterlegt sind. Eine Steuereinheit 30 vergleicht die Istwerte der Amplituden und Frequenzgänge, die über die Schallerzeugungseinheit 28 aufgezeichnet werden, mit den zugehörigen Sollwerten aus der Datenbank, sodass auf einfache Weise erkannt werden kann, ob das über die Fronteinheit 12 zugefügte Einweggut 18 auch tatsächlich zerstört wurde. Insbesondere erkennt die Steuereinheit 30 über den Sensor 16 jeweils die Einweggutart des zugefügten Einweggutes, sodass sie die entsprechenden Sollwerte aus der Datenbank für den Vergleich mit dem über die Schallerfassungseinheit 28 ermittelten Istwert bzw. den ermittelten Istwerten verwenden kann.For this purpose, a database is stored in a memory element 32, for which setpoint values of the amplitudes and typical frequency responses are stored for each disposable product type. A control unit 30 compares the actual values of the amplitudes and frequency responses that are recorded via the sound generation unit 28 with the associated setpoint values from the database, so that it can be easily recognized whether the disposable material 18 added via the front unit 12 has actually been destroyed. In particular, the control unit 30 recognizes the disposable material type of the added disposable material via the sensor 16 so that it can use the corresponding setpoint values from the database for the comparison with the actual value or the determined actual values ascertained via the sound acquisition unit 28.

Bei der Schallerfassungseinheit 28 kann es sich insbesondere um ein Mikrofon handeln, welches die beim Kompaktieren des Einweggutes 18 entstehenden Geräusche aufzeichnet. Zusätzlich oder alternativ kann die Schallerfassungseinheit 28 auch einen Körperschallabnehmer umfassen, mit dessen Hilfe der erzeugte Körperschall erfasst und mit den entsprechenden Sollwerten verglichen wird.In the sound detection unit 28 may be in particular a microphone, which records the resulting during compacting the disposable material 18 noise. Additionally or alternatively, the sound detection unit 28 may also include a structure-borne sound pickup, with the help of which the generated structure-borne noise is detected and compared with the corresponding desired values.

Hat die Steuereinheit 30 eine relevante Abweichung zwischen dem Istwert und dem erwarteten Sollwert ermitteln, die so groß ist, dass auf einen Betrugsversuch zurückgeschlossen werden kann, so nimmt die Steuereinheit 30 das Pfandsystem 10 außer Betrieb. Unter einer relevanten Abweichung wird insbesondere verstanden, dass die Abweichungen außerhalb eines Toleranzbereichs um den Sollwert liegt. Alternativ kann in der Datenbank auch gleich ein Sollbereich hinterlegt sein, sodass eine Abweichung dann ermittelt wird, wenn der Istwert außerhalb des Sollbereichs liegt.If the control unit 30 has determined a relevant deviation between the actual value and the expected setpoint that is so great that it is possible to deduce a fraud attempt, the control unit 30 deactivates the deposit system 10. A relevant deviation is understood in particular to mean that the deviations lie outside of a tolerance range around the desired value. Alternatively, a setpoint range can also be stored in the database, so that a deviation is determined when the actual value lies outside the setpoint range.

Das Pfandsystem 10 kann nach der Außerbetriebnahme insbesondere nur durch autorisierte Personen wieder aktiviert werden.The deposit system 10 can be reactivated after decommissioning in particular only by authorized persons.

Zusätzlich oder alternativ kann beim Vorliegen einer Abweichung und somit des Verdachtes eines Betruges auch eine Fehlermeldung erzeugt werden. Diese kann beispielsweise über einen Bildschirm 34 des Pfandsystems 10 ausgegeben werden und/oder an eine zentrale Überwachungseinheit in eine Zentrale der das Pfandrücknahmesystems 10 betreibenden Firma übersandt werden.Additionally or alternatively, an error message can be generated in the presence of a deviation and thus the suspicion of fraud. This can be output for example via a screen 34 of the deposit system 10 and / or sent to a central monitoring unit in a center of the deposit-taking system 10 operating company.

Darüber hinaus ist es auch möglich, dass über eine Alarmeinheit 36 ein akustischer und/oder optischer Alarm ausgegeben wird, sodass andere Personen alarmiert werden und eine abschreckende Wirkung ausgeübt wird, da die Betrugsversuch durchführenden Personen befürchten müssen, unmittelbar erkannt zu werden.In addition, it is also possible that an alarm and / or visual alarm is issued via an alarm unit 36, so that other people are alerted and a deterrent effect is exercised, since the persons attempting to commit fraud must fear being immediately recognized.

Insgesamt wird durch das zuvor beschrieben Verfahren, also das Sicherstellen der tatsächlichen Kompaktierung und Zerstörung der Sicherheitsmerkmale des Einweggutes 18 über den hierbei entstehenden Schall, erreicht, dass zeitnah und zuverlässig erkannt werden kann, wenn ein der Fronteinheit 12 zugefügtes Einweggut 18 innerhalb der Sortierstrecke 26 verbotenerweise wieder entnommen wird und nicht dem Kompaktor 20 zugeführt wird.Overall, by the method described above, ie ensuring the actual compaction and destruction of the security features of disposable material 18 on the resulting sound, achieved that timely and reliable can be detected when a front unit 12 added disposable 18 within the sorting path 26 illegal is removed again and is not supplied to the compactor 20.
