Definitions

  • the invention relates to an empties return device for a container of at least one predetermined type. Furthermore, the invention relates to a method for operating an empties return device for an empties of at least one predetermined type.
  • a conventional empties return device such as a bottle return device, is usually designed to bring an empties placed in a receiving chamber of the empties return device into a storage container and a deposit of the empties emptied as a monetary amount or as a credit to a user of the empties return device issue.
  • the user places a foreign object in the receiving chamber instead of the empties with the respective pledge. If the empties return device does not recognize in this case that the foreign object does not correspond to the empties with the deposit to be paid out, the operator of the empties return device loses the deposit amount.
  • Some empties return devices therefore have a bar code reader which is designed to recognize a bar code attached to a container.
  • An empties return device with a bar code reader is usually designed so that only after a recognition of the bar code on the respective empties the pledge is issued.
  • Such an empties take-back device has the disadvantage that they have only a low security with regard to the detection of counterfeit products to be repelled.
  • a bar code reader is not suitable for distinguishing empties with a bar code from a rolled-up copy.
  • a security feature is also known, which can be evaluated via an additional optical detection unit.
  • Glass bottles as they are common in the catering, usually have no safety markings. Due to the expensive evaluation unit for the security feature and the system-related exclusion of glass bottles, the recognition reliability of the bar code method can not be achieved to the extent necessary by additional evaluation of a security feature.
  • empties return devices are known from the prior art, which are equipped with a camera and an image processing device.
  • the image processing device is designed to distinguish the document from a foreign object on the basis of an image provided by the camera.
  • Such reverse vending machines are used, for example, in DPG-certified automatic reverse vending machines in beverage markets.
  • the camera and the appropriate image processing device are comparatively expensive. The use of Camera and the image processing device is therefore not possible with a cost automatic reverse vending machine.
  • an empty bottle return device is described with at least one optical sensor for determining at least one diameter of a parked object. While the at least one optical sensor is moved past the object via a linear unit, such as a slide or a manually closable door, the at least one optical sensor measures the object contour. With a suitable object contour, an electronic control unit recognizes the parked object as a bottle.
  • the empty bottle return device requires a comparatively long acquisition time and a relatively expensive linear unit.
  • only a coarse screening of the object contour can be detected with the empty bottle return device.
  • the evaluation electronics is hardly able to differentiate bottles of similar sizes from the provided sensor data.
  • a method for operating an empties return device for an empties of at least one predetermined type comprising the steps of: at least once scanning an empties object arranged in a receiving chamber of the empties return device with an optical radiation by means of a light source; Receiving the emerging from the emptied at least once emptied object optical radiation by means of a light detector; Analyzing the received optical radiation according to at least one predetermined criterion; and accepting / rejecting the empties object based on analyzing the received optical radiation.
  • FIG. 1 shows a schematic representation of a first embodiment of the empties return device.
  • empties take-back device has a receiving chamber, in which a user of the empties return device can turn off an empties object 10 to be examined in the following.
  • a user of the empties return device can turn off an empties object 10 to be examined in the following.
  • the empties return device may be designed to take back an empties having at least one predetermined shape, at least one predetermined size and / or width, at least one preferred manufacturer and / or at least one specific material.
  • a bottle, a can, a jar, a can, a box and / or a plastic packaging can be understood.
  • the empties take-back device is suitable, for example, for empties made of glass, plastic, metal, cardboard and / or paper. The operation of the empties take-back device is not affected by a partial training and / or coating of the empties an opaque material, such as a metal.
  • the empties return device described here is also designed to examine the empties object 10 when a user inserts the empties object 10 in different positions in the receiving chamber in comparison with a conventional bottle return machines.
  • the operation of the empties return device can be easily extended to the effect that the empties object 10 is recognized as a can of a particular manufacturer when the user puts the empties object 10 with a downwardly facing opening on a surface of the receiving chamber.
  • the empties object 10 can be recognized as a bottle of a certain size, regardless of whether the empties object 10 is provided with upward facing opening or laterally aligned opening on the bottom surface of the receiving chamber.
  • the examples described here are also expandable to other types and positions of the empties object 10.
  • the empties take-back device is therefore also suitable for users who, for example, can not read.
  • the empties take-back device comprises a light source 12 and a light detector 14 cooperating with the light source 12.
  • the light source 12 is designed to emit an optical radiation 16a.
  • the emitted optical radiation 16a may have a predetermined total intensity.
  • the emitted optical radiation 16a may be within a predetermined wavelength spectrum.
  • the light source 12 may be adapted to the optical Radiation 16a to emit with a preferred spectral intensity distribution.
  • the wavelength range of the emitted optical radiation 16a can be selected taking into account the at least one empties preferred for taking back.
  • the wavelength range of the emitted optical radiation 16a may be between 700 nm and 850 nm.
  • Advantageous embodiments for suitable wavelength ranges of the emitted optical radiation 16 a result from the materials of the preferred empties object 10.
  • optical radiation 16a is oriented so that the emitted optical radiation 16a at least partially on an outer surface of the disposed in the receiving chamber empties object 10 hits. If the empties object 10 is at least partially translucent, at least a portion of the empties object 10 is transilluminated by a transmission 16b of the emitted optical radiation 16a. If the at least one subregion of the empties object 10 comprises a material which has an absorption spectrum in which the transmission 16b lies, an emission is additionally excited. The optical radiation 16c emerging from the empties object 10 thus has an altered light intensity and / or an altered optical spectrum in comparison to the optical radiation 16a emitted by the light source 12.
  • the light detector 14 has at least one detector surface 18, by means of which the optical radiation 16c emerging from the empties object 10 can be received.
  • the light detector 14 may be, for example, an infrared diode array.
  • the light detector 14 is arranged on the empties return device such that a predetermined measurement position of the light detector 14 with respect to the empties object 10 can be maintained during the reception of the emanating from the empties object 10 optical radiation 16c.
  • the light source 12 can also be arranged on the empties return device such that a predefined sending position of the light source 12 with respect to the empties object 10 is maintained during the emission of the optical radiation 16a.
  • the light source 12 and the light detector 14 are not displaced from their positions during their operation. This eliminates the need for an adjustment for the light source 12 or for the light detector 14. The steps and the cost of producing a suitable adjustment can thus be saved.
  • the light source 12 and the light detector 14 may be formed stationary.
  • the reverse vending apparatus described herein is not limited to such an embodiment.
  • the unit may be brought to a predetermined measurement position. After the measurement, the unit can be placed in a protective position again.
  • the light detector 14 is coupled, for example via a line 20, to a control and evaluation device 22 which is designed to analyze the received optical radiation 16c according to at least one predetermined criterion and to provide a corresponding analysis signal.
  • Analyzing according to the at least one predetermined criterion may also be understood as applying an algorithm. Special execution options of the control and evaluation 22 will be discussed below.
  • the light source 12 may be connected via a further line 24 to the control and evaluation device 22.
  • the control and evaluation device 22 may in particular be designed to activate the light source 12 and the light detector 14 after detecting an arrangement of the empties object 10 in the receiving chamber of the empties return device. In this way, an operation of the empties return device is guaranteed with a relatively low energy consumption.
  • the light source 12 can be designed such that a power of the optical radiation 16a emitted by the light source 12 can be controlled by the drive and evaluation device 22.
  • the control and evaluation device 22 may be designed to output an intensity control signal to the light source 12, taking into account the optical radiation received by the light detector 14, preferably its intensity.
  • the control and evaluation device 22 may be designed, in particular, to determine an optical property of the illuminated exterior of the empties object 10 and / or of the illuminated subarea of the empties object 10, taking into account an optical radiation 16c impinging on a detector surface 18.
  • a property may be, for example, an absorption property, a reflection property, and / or an emission property.
  • the light detector 14 comprises a plurality of detector surfaces 18. In this case, it is possible to specifically examine different portions of the empties object 10 with respect to their optical properties. Since the evaluation of the information determined on the detector surfaces 18 regarding the optical properties of the different subareas of the empties object 10 can take place simultaneously, the investigation of the specific optical properties of the different subregions of the empties object 10 can be carried out relatively quickly.
  • the light detector 14 may have a plurality of comparatively small detector surfaces 18.
  • the light detector can be formed from several inexpensive short modules.
  • the light detector 14 may be designed to determine at least one intensity value of the optical radiation impinging on the at least one detector surface 18.
  • the at least one intensity value defined by the light detector 14 may comprise an overall intensity, a spectral distribution and / or an intensity in at least one predetermined wavelength range of the optical radiation 16c impinging on a detector surface 18.
  • a light detector 14 with only one detector surface 18 can determine a spectral intensity distribution of the optical radiation 16c emerging from the empties object 10.
  • a light detector 14 has a plurality of detector surfaces 18, an additional spatial intensity distribution of the optical radiation 16c emerging from the empties object 10 can be determined.
  • the drive and evaluation device 22 is preferably designed to differentiate a pattern of optical properties taking into account the intensity values provided by the light detector 14 Defines subareas of the empties object 10. This can also be designated such that a characteristic emission, absorption and / or diffraction pattern of the empties object 10 is determined.
  • a suitable control and evaluation device 22 is, for example, a microcontroller circuit or a PC.
  • the optical property can be compared with at least one comparison value.
  • the at least one comparison value can for example be stored on a database in a database memory 23.
  • the database memory 23 may be formed as a subunit of the control and evaluation device 22 or separated therefrom.
  • the at least one comparison value preferably corresponds to at least one comparison property, as occurs when a partial area of the at least one type of empties that is preferred for the return is illuminated.
  • the at least one comparison property is a transmission coefficient and / or an emission coefficient of the at least one material preferred for the return.
  • the at least one comparison characteristic may comprise a pattern of spatial intensity distributions, as can be ascertained by scanning a preferred empties due to a shape, a coating and / or a material composition of the type of empties preferred for the return. In this case, different patterns of spatial intensity distributions, as they occur in different positions of the empties, can be stored on the database for one type of empties.
  • the control and evaluation device 22 detects in a comparison that a deviation between the at least an optical property and the at least one comparison property is within a predetermined deviation range, it is determined that the empties object 10 is a preferred type of empties.
  • the control and evaluation device 22 outputs as an analysis signal an acceptance signal 26 to an acceptance device 28.
  • the acceptance device 28 can be designed to automatically arrange the empties object 10 in a storage chamber after receiving the acceptance signal 26. Subsequently, the acceptance device 28 outputs a deposit issuing signal 30 to a deposit issuing device 32.
  • the deposit issuing facility 32 is designed to issue a deposit corresponding to the empties object 10 as a monetary amount or as a credit to the user of the empties take-back device after receiving the deposit issuing signal 30. The user who has placed the correct empties in the receiving chamber of the empties return device thus receives the correct deposit of the empties.
  • control and evaluation device 22 recognizes that the empties object 10 does not have the at least one predefined optical property of a type of empties preferred for taking back, the control and evaluation device 22 recognizes the empties object 10 as a foreign object. In this case, the control and evaluation device 22 outputs as an analysis signal a reject signal to a (not shown) rejection device.
  • the rejection device may comprise at least one sound output and / or display device, the activation of which indicates to the user that the empties object 10 introduced into the receiving chamber is not accepted.
  • the control and evaluation device 22 may additionally be designed to distinguish between different types of empties suitable for taking back.
  • the driving and Evaluation device 22 additionally determines a type of empties object 10 in this case.
  • Information relating to the specified type of empties object 10 can be forwarded to the components 28 and 32 as an acceptance signal 26 and as a deposit issuing signal 30.
  • the acceptance device 28 may be configured to arrange different types of empties into different storage chambers. This saves a sorting of empties when emptying the empties return device. In addition, in this way, the space available in the empties take-back device can be used more efficiently.
  • a reliable identification of the empties object 10 by the empties return device is also ensured if instead of the entire empties object 10 only a portion is illuminated.
  • a partial region of the empties object 10 is preferably transilluminated, which is specific with regard to the shape, the size / width, the manufacturer identification and / or the material composition of the empties object 10.
  • the light source 12 and / or the light detector 14 compared to the empties object 10 can be made relatively small. This reduces the space requirement of the light source 12 and the light detector 14th
  • the empties take-back device may additionally comprise a metal detector (not shown). This is advantageous if the empties take-back device for a return of empties made of metal, such as a can, is used. In this case, in addition to the at least one optical property of the empties, the metal property of the empties can be seen. Thus, the empties of metal can be safely distinguished from a paper dummy.
  • a data matrix and / or a bar code reading unit may also be used to display, in addition to the shape, size, width, material composition and / or manufacturer of the empties object, an empties object 10 detect detectable barcode. This provides additional security in distinguishing a preferred empties from a foreign object.
  • FIG. 2 shows a schematic representation of a second embodiment of the empties return device.
  • the empties object 10 for example a mason jar, can be arranged in a receiving chamber of the empties return device, which has a reflective surface 40 on one side.
  • the reflective surface 40 may be planar or curved.
  • the light source 12 and the light detector 14 may be arranged together on one of the reflective surface 40 opposite side of the receiving chamber. It is thus ensured that an optical radiation 16 emitted by the light source 12 strikes an outside of the empties object 10, at least partially transmitted through the empties object 10 and after exiting the empties object 10 from the reflective surface 40 onto the empties object 10 Empties object 10 is reflected back. Subsequently, the reflected optical radiation again transmits through the empties object 10 before it strikes at least one (not sketched) detector surface of the light detector 14.
  • the reverse vending machine of the FIG. 2 has the advantage that the optical radiation 16 receivable by means of the light detector 14 has a longer beam path through the empties object 10.
  • the optical radiation 16 receivable by means of the light detector 14 has a longer beam path through the empties object 10.
  • Even with an empties object 10, which has no significant optical properties, a characteristic absorption and / or diffraction pattern can be reliably detected by means of the procedure described here.
  • the components 12, 14 and 20 to 32 of the empties return device of FIG. 2 correspond to the basis of FIG. 1 already described embodiment. For a further description of these components is therefore omitted.
