Description

 P R O D U C T D E S T E S O N S - V O R I C H T U N G

The invention relates to a device for detecting individual or multiple product identifiers associated with the respective product and representing the respective product and / or selected features and / or properties of this product.

In the context of a constantly increasing environmental awareness on the one hand, and an increasing awareness of the finiteness of natural raw materials on the other hand, take-back and deposit systems, the recycling of the raw materials used for product manufacturing or their reprocessing or their proper disposal gain more and more importance. It has proven to be sustainable to increase the return rate of products of interest in this context through suitable deposit systems. These efforts are flanked by rising commodity prices, which further increase the need for such deposit systems. In this context, there is a need for as counterfeit-proof labeling of the respective products or their packaging, in order to limit the existing abuse possibilities as far as possible. It has proven to be useful if the affected products in this context are both provided with a clear product identification, as well as with a tamper-proof security feature as possible. In connection with the training of security mechanisms to prevent counterfeiting and counterfeiting, sufficiently complex technologies are available to exclude such counterfeits with almost certainty. However, these are often inappropriate in connection with the mentioned deposit systems, because the corresponding security solutions are disproportionately expensive in relation to low-price products offered.

From DE 103 04 1 19 A1, various possibilities for checking the authenticity of pledge markings, for example using barcodes, wavy lines, geometric representations and images as well as the use of chemical or magnetic markings are known in this context, which are then canceled in a reverse vending machine.

In addition, from DE 20 2005 005 915 U1 a reverse vending machine for empties article is already known, which is provided with a chute, which is provided with a completely arranged detection system which detects its mark from several sides as the lien passes by. A devaluation is carried out by the token is associated with a coil, which can first be queried via a weak excitation coil and then deleted via a fall path in the following arranged strong excitation coil.

From DE 20 2007 003 767 U1 an all-round reading of a deposit mark is also previously known. In this case, the solution according to the invention provides for placing an empties article on a conveyor belt, this conveyor belt being provided with a point of interruption, in the area of which the empties are checked from all sides, using non-contact means, such as a code laser or Inkjet heads, a devaluation of the pledge is performed.

Based on this prior art, the invention is based on the object to provide a device for the detection of product-identifying product identifier, on the one hand as high as possible Erfassungsgeschwindig- On the other hand, it offers increased security against possible misuse of such deposit systems.

The object underlying the invention is achieved with a device according to the features of the current claim 1. Advantageous embodiments of the invention can be taken from the dependent claims 2-9.

According to the current claim 1, the device according to the invention for detecting product-related product identifiers identifying this product provides at least one detection ring which is provided with detection devices distributed over the circumference of the detection ring, preferably cameras, for the detection of product identifiers. The ring arrangement of the detection device ensures that all, approximately distributed over the circumference of the product, this product identifying product identifier, at least can be detected and read at least approximately simultaneously. For this purpose, the cameras are arranged distributed over the circumference, that in each case a 360 ° detection is realized within the inner circumference of the detection ring in which the distance of the cameras depending on their respective image capture angle is selected so that a complete coverage, so a 360 ° detection is realized within the detection ring. As a result, the visual product identifiers associated with the products moved by the detection ring are detected in any case using the image acquisition realized by the cameras. In order to ensure that an automatic detection of the product identifiers takes place, the detection rules are additionally assigned one or more motion detection devices in such a way that the image acquisition of the cameras is activated synchronously to the passage of a product through the detection ring.

In a concrete embodiment, the products by means of a conveyor or other propulsion or by gravity, so in free fall, by a then horizontally arranged detection ring and thus persistently by one or more detection rings are moved. In doing so, the tion detection devices and the image acquisition systems are tuned such that a detection of the associated product with the visible product identifiers is ensured in any case, for example, the image capture upstream motion detection devices at such a distance from the image capture so the or the detection ring / s are arranged that the proper Image recognition is ensured in any case.

In an advantageous embodiment of the invention, in addition to the usual product-identifying features, namely the product identifier, usually an EAN barcode or for the North American area a UPC barcode, and / or other identification features are applied to the product. The European Article Number (EAN) is an internationally distinctive product identifier for merchandise. The number consists of 8 or 13 digits, of which the first 2 or 3 or 7, 8 or 9 digits centrally by the so-called GS 1 group and assigned to the manufacturer on request as a Global Loca- tion Number. The invention additionally provides for the identification of the products by a unique product ID, a unique device identification (UDI). This is a combination of numbers or characters that can be used to uniquely identify hardware and software, people, communications, objects, or entities within a given category. The assignment of the numbers must be done in a way that excludes the multiple assignment of the same number for different entities. Often, a reversibly clear relationship is required. This means that such a product ID is always assigned only once and also allows a perfect identification of a product. As a rule, the marking of products with the UDI takes place in the form of a machine-readable two-dimensional barcode, a so-called QR code or data matrix code. In the context of the solution according to the invention, therefore, these product identifiers are supplied to automatic image acquisition. Furthermore, the solution according to the invention provides for the use of an additional security feature, namely a pigment label, in order in particular to increase the security against counterfeiting. The solution according to the invention is thus based on the fact that, at least in this embodiment, the products to be detected are each provided with three features identifying the product, which is prior to

Background of the above-mentioned simultaneous detection of multiple product-identifying features is a useful development of the solution according to the invention. The pigment label is invisible to the human eye by, for example, the pigments forming the pigment label being invisibly integrated into one or more product labels of the respective product for the human eye. In that regard, an advantage of the security feature and thus also an essential contribution to its security against counterfeiting is that it is invisible and as such is not perceived at all, which in itself constitutes a significant contribution to the protection against counterfeiting. In addition, the integration of such pigments into a printing ink, which must be used anyway for the application of product information, to realize comparatively inexpensive.

In this case, this pigment label has a pigment arrangement which is excited to fluorescence with visible light, which is irradiated onto the pigment label, in particular when passing through the detection ring, such that this fluorescence effect can be read out by means of a special detection device. The integration of this pigment arrangement in an ink is associated with some technical effort, so that thereby the counterfeit security of the inventive device is sustainably improved. This fluorescence effect can be detected in a conventional manner by means of photoelectric sensors.

In a concrete embodiment, the photoelectric sensors are also arranged distributed over the inner circumference of the detection ring, in particular in the interspaces between the along the inner circumference of the detection ring of the arranged cameras. This ensures that the recording of the pro- product identifiers and the security feature is carried out at least substantially simultaneously.

In this case, the detection of the product identifiers by the image acquisition systems takes place with visible light, while the detection of the fluorescence effect can take place with the aid of photo-electric sensors in one possible embodiment with laser light, thus the detection ring (s) has two light sources each having a different wavelength associated with emitted light. In an alternative embodiment, both the image capture of the product characteristics and the detection of Fluoreszenzeffekts each with visible light, so that the detection of Fluoreszenzeffektes and the image-capturing product labels are carried out simultaneously, thus the passage speed of the products can be increased by the detection ring. This is achieved, for example, by generating light, preferably in the infrared or ultraviolet range, by means of LEDs distributed over the inner circumference of the detection ring, which light is suitable both for image acquisition and for the generation of the fluorescence effect to be detected. In an advantageous embodiment, the product features detected and / or read by means of the detection device are transmitted to a connected data acquisition device, stored at this point and / or sent for further processing. In particular, by means of the connected data acquisition device, a deposit amount to be paid out may be determined and output via an output device. In addition, the calculations required for further billing, such as collecting societies, can be made on the basis of the data collected in this context. Incidentally, it may be noted in the database that a deposit amount associated with the identified product has been disbursed, and further the tied product may be canceled, so that further payout is prevented. In a concrete embodiment, the detection device according to the invention can be arranged in a return unit for goods to be returned. In this case, the detection ring is arranged horizontally within a return chute within the return unit, for example, such that the goods returned for security purposes fall through the chute and thus through the detection ring, whereby the product features identifying the respective product are detected and / or read during the flyby of the respective product become.

An advantageous use of the product detection device according to the invention is accordingly the use for the detection of deposit products, in particular returnable bottles and their subsequent devaluation in a centrally managed database.

The invention will be explained in more detail below with reference to an exemplary embodiment shown by way of example only in the drawing:

Show it:

1 shows a device for the detection of product features in a schematic diagram,

 Fig. 2: A detection device of the device shown in Figure 1, in relation to a product to be detected, also in a schematic diagram

According to the above embodiments, the product detection device 1 according to the invention for detecting product identifiers associated with a product 2, this product 2 identifying product - namely in this embodiment comprising a security feature S, a product identifier, here the so-called EAN barcode EAN as a machine-readable Barcode, as well as a single-unique product identifier, the Unique Device Identification UDI. The latter is a machine-readable product marking, the usual As a two-dimensional barcode, ie as a QR code or as a data matrix code, it is already contained on a large number of products. This marking is intended to enable globally unambiguous product labeling so that a clear identification of the individual product is possible via the aforementioned 2D code. As a result, the product 2 is characterized as such, so that, for example, a deposit bottle can be distinguished from another deposit bottle, even if it is the same product. Such a unique identifier is helpful, for example, in connection with deposit systems, so that by storing the product ID, for example, a devaluation of the deposit can be made so that no deposit can be required for the deposit bottle in question

The EAN barcode EAN contains a clear description of the product 2 in question, which is usually affixed or printed on the product 2 as a barcode. By reading this feature so you get a unique

Definition of the Respective Product 2. Within the scope of the invention, either one or both of the aforementioned codes can be read out with the aid of the product detection device 1 according to the invention in order to increase safety. Furthermore, the product detection device has a detection ring 3, distributed over the circumference of which are a plurality of detection devices, here cameras 4. In this case, the cameras 4 are arranged as a function of their image detection angle such that an all-around detection of the product 2 to be detected is made possible via the cameras 4.

To further increase the security against counterfeiting, which, for example, ensures that the above-mentioned markings are not used in conjunction with an exchanged product, it makes further sense to provide the corresponding product 2 inseparably with a security feature S, ideally. In the present embodiment, this is an imprint which is carried out directly on the product 2 and is accordingly inseparably connected to it by adding pigments into the ink used are introduced, which cause a luminous effect or a fluorescence effect upon irradiation of a light in the visible range, in a defined wavelength, which is not present in a possibly exchanged or imitated product. In that regard, an additional contactless verification of the product 2 is given to its authenticity.

The fluorescence effect is detected by means of the photoelectrical sensors 6 distributed in the circumference of the detection ring, preferably between the cameras 4. As a result, in the exemplary embodiment of the invention, the detection of the product identifications identifying the respective product takes place simultaneously the verification of the security feature S, which is realized in the present case by a pigment label.

As a result, in the case of the product 2 shown in FIG. 1, in addition to the identification of the product 2 via the EAN barcode, a unique identification of the product as such takes place via the product ID, whose authenticity can be checked with an additional security feature S. is.

The detection of this product 2 takes place in that the product 2 is moved by the detection ring 3 of the detection device 1 according to the invention.

The product 2 can be moved manually or by means of a conveying device through the detection ring 3, but also, as shown in Fig. 1, are simply moved by a falling motion following the gravity of the detection ring 3. In this case, even if the product identifiers S, UDI and EAN identifying the product 2 are distributed over the product 2, they can be detected simultaneously via the cameras 4 distributed on the detection ring 3 and subsequently evaluated. The image acquisition by the cameras 4 is activated in such a timely manner by motion sensors integrated into or in front of the detection ring 3 that the recognition of the product features is integrated by the sensors integrated in the detection ring 3

Cameras 4 is ensured. It has proven useful if both the image capture by means of the cameras 4, as well as the activation of Fluoreszenzeffektes each with visible light, preferably in the infrared or ultraviolet range, because then both the security feature and the product identifier can be detected simultaneously. As a result, therefore, the detection speed of the detection device 1 is increased.

The light required for the detection of the fluorescent effect, as well as for image capturing is ideally also means tektionsringes over the inner circumference of the de- 3 arranged LEDs distributed ensured 6, the robustness and lifetime of the application described herein is appropriate.

As a result, the detection device 1 according to the invention thus makes it possible to detect the features S, ID and EAN identifying the product 2 at the same time in the flyby, ie. H. can be recognized in a minimal amount of time, and due to the additional security feature beyond a higher counterfeit security for the inventive method is guaranteed.

For this purpose, it must be ensured, as shown in FIG. 2, that the cameras 4 provided in this embodiment as a detection device are arranged at a distance from one another in such a manner that in each case an all-round detection of the products 2 guided through the detection ring 3 is ensured. The distance between the cameras 4 distributed over the detection ring 3 thus results from the image capture angle of the cameras 4 used. In addition to the evaluation of the images acquired by the camera 4, it is then possible to detect via the security feature S whether it is an authentic image Original product trades, via the EAN barcode, what kind of product it is, and finally the unique product ID identifies the individual product 2 as such and, for example, a deposit valuation in connection with this specific product 2 after the evaluation of the product has been completed by means of

Cameras recorded product characteristics are performed in a downstream central database. For this purpose, the cameras 4 are preferably wireless, et wa via a radio link 5, connected to a data acquisition or data processing device that releases, for example, as a result of a deposit payment or not and incidentally a log of the collected products 2 for further billing purposes, such as in connection with recovery or reprocessing companies performs.

FIG. 3 shows in a further side view again in the product detection device 1 according to the invention in a side view in conjunction with a product 3 to be detected, here as an example of a deposit bottle, which has a security feature S, a unique device ID UDI and an EAN bar code EAN is uniquely identified. The product detection device 1 essentially comprises a detection ring 3, which is provided on its inside with a plurality of cameras 4 arranged so as to be distributed over the inner circumference of the detection ring 3 such that a 360 ° detection of the product 2 is possible with the aid of these cameras 4 is, so that at least one or more cameras 4 can recognize the distributed over the circumference of the product 2 product features, in particular the unique device ID UDI and the EAN barcode EAN. In addition, distributed over the circumference of the detection ring 3 arranged photo-electric sensors 6 are arranged, which serve to detect the security feature S. In the present exemplary embodiment, this is a so-called pigment label, ie a pigment integrated in one or more of the imprints or labels of the product 2, specifically in its printing ink, that under irradiation of light in a defined wavelength, but not necessarily in the present example is excited to fluorescence in the visible range, for example in the infrared or ultra-violet range, this effect in turn can be detected using the photo-electric sensors 5. In this case, these sensors 5 are also arranged distributed over the circumference according to the illustration in Figure 3 but also in Figure 4 such that a possible fluorescence effect is detected and also transmitted to a downstream external device. It is advantageous both for the detection of the fluorescence effect and also for the product features S, UDI and EAN if the inner area surrounded by the detection ring 3 is well illuminated or illuminated in the correct wavelength and light intensity that additionally distributed over the circumference of the detection ring 3 lighting elements, preferably LEDs 6 are arranged.

The illustration in Figure 4 shows the detection ring 3 shown in a side view in Figure 3 in a plan view, from which it is seen that distributed over the circumference of the detection ring 3 arranged alternately cameras 4 and the photoelectric sensors 5 are arranged, and at regular intervals that for illuminating the region LED ' s enclosed by the detection ring 3 for illuminating this area.

Thus, the solution according to the invention allows a faster product detection with a higher degree of security, which can be used for example with advantage in connection with deposit or other take-back systems. Of course, the product detection device 1 according to the invention can also be used in all other areas in which a rapid product detection requires or otherwise advantageous.
