Definitions
- the invention relates to a method for detecting, Recognizing and sorting objects of a material stream, in particular wood waste and wood fiber products such as paper and Kartonagen, according to the preamble of claim 1, as well as a Device for detecting, recognizing and sorting objects a stream of material according to the preamble of claim 9.
- Thermally recyclable waste mixtures are often used for energetic use by burning used. Under the aspect of the sustainable use of valuable raw materials but it makes sense, from appropriate waste mixtures Sort out recyclables clean and use them as recycled goods. For a long time that is Use of waste paper and cardboard in the paper industry known and is now being carried out intensively.
- a method of this type is known, for example, from EP 1 048 363 A2.
- the material flow to be sorted is present Radiation sources and through the detection range of cameras moved along a rectilinear direction of movement, wherein the Cameras are the wavelengths of the objects of the Material stream emitted radiation and their intensity detect and control the following Sorting devices serve.
- the wavelength of the reflected from the objects Radiation is determined, an assignment of the object to a certain faction is tried, and in the event that there is none Group can be clearly assigned, then the Intensity differences of the reflected radiation of be determined different sub-areas of the object. For example, large intensity differences of the reflected radiation from different object areas, this indicates printed paper, while low Intensity differences rather close to cardboard boxes, as cardboard generally hardly printed with small font is.
- EP 1 048 363 A2 the idea is further expressed, a Line camera to use only a strip of a Object maps, with a movement of the object more Strips are recorded one after the other so as to shed light on to get the entire object.
- the reflected wavelength of such a strip integral detected, a differentiation in terms of the reflected Wavelengths of different areas of a strip, however not made.
- Claim 1 relates generically to a method for detecting, recognizing and sorting Objects of a material flow, in particular wood waste and Wood fiber products such as paper and cardboard, the pre Radiation sources and through the detection range of cameras, to control subsequent sorting serve, moved along a rectilinear movement direction is, whereby the detection range of the cameras strip-shaped across the direction of movement of the objects extends and the cameras the wavelengths of the Radiated objects of the material flow detect.
- claim 1 provides that for several areas of this strip-shaped section the Intensity of an object of the material flow emitted radiation detected for multiple wavelengths becomes.
- Claim 2 provides that the Control of the subsequent sorting by means Comparison of detected, location-dependent Wavelength spectra with previously measured wavelength spectra is made. Based on these comparisons of the collected location dependent, spectral reflectance intensities of measured object with previously collected product samples a classification of the object can be performed. Various materials can be predefined are taught and then assigned to material classes. Based on the classified gauges, the locomotion of Objects in the conveying direction of the sorting belt and the rapid Repetition of the measurement results in such a way classification-capable image of the object to be recognized. This image is evaluated using algorithms and accordingly the user's specifications of a run or one Assigned to discharge fraction.
- Claim 3 therefore provides a possibility of reducing the amount of data to be evaluated before, by only selected, discrete Wavelength ranges for controlling the following Sorting devices are used.
- the objects with electromagnetic radiation in certain To irradiate wavelength ranges are particularly advantageous, the objects with electromagnetic radiation in certain To irradiate wavelength ranges.
- the wavelengths of the Radiation sources emitted radiation Wavelength range from near infrared to ultraviolet Include light.
- the generation of evaluable wavelength spectra can on done different way.
- the wavelength of the objects of the Material stream emitted radiation as a reflection spectrum is detected.
- the Wavelength of the objects of the material flow emitted radiation detected as a transmission spectrum becomes. The decision on choosing one of these two Methods are added depending on the composition of the material flow be meeting.
- Claim 9 finally provides a device for detecting, Recognizing and sorting objects of a material stream, in particular wood waste and wood fiber products such as paper and Cardboard boxes, in front, the radiation sources and cameras for Control of subsequent sorting devices comprises.
- the detection range of the cameras, through which the material flow is moved along a rectilinear movement direction is while strip-shaped transversely to the direction of movement of the objects educated.
- the cameras are detectors for the wavelengths of the objects of the material flow emitted radiation.
- the characterizing features of claim 9 is provided in devices of this kind, that the cameras are spatially resolved spectrometers which deals with multiple areas of an object, respectively simultaneously within this strip-shaped section lie, measuring the intensity of this object allow emitted radiation for multiple wavelengths.
- an NIR area camera is used for this purpose.
- Fig. 1 shows a schematic side view of a Embodiment of a sorting plant section for sorting of thermo energetically usable objects 7, 8, 9 as Wood waste, wood fiber products (e.g., waste paper, cardboard, Scraps of fabric), plastic waste (e.g., PET bottles, foils) as well as mixed fractions of different quality and Condition in which e.g. various existing substances, such as Paper 8, cardboard 9 or plastics 7 on at least one Sorting belt 1 lie and along a direction of movement. 2 be transported. At least one area of Sorting belt surface is characterized by at least one radiation source 3 irradiated. The radiation sources 3 can also use this Reflectors 4 be provided.
- the radiation sources 3 can also use this Reflectors 4 be provided.
- the of the individual objects 7, 8, 9 reflected radiation is detected by a camera 5 and the objects 7, 8, 9 on the basis of the determined data of a assigned to certain class of material or fraction 11, 12, as will be explained in more detail. Because of this assignment Sorting devices 10, 14 such as suction or Blow nozzles activated.
- the physical separation of objects 7, 8, 9 can in this case by apparatus measures such as separating rollers, Separating tapes or separating edges 13 are supported.
- Fig. 2 shows an alternative embodiment, which in Difference to the embodiment shown in Fig. 1 a Separation of the mix in three fractions allows.
- This is achieved by, for example, another Conveyor 15 is provided on the means of a first sorting device 10, 14 about all cardboard boxes. 9 be lifted and head towards 16 to a collection point be transported. With the help of a second one Sorting device 10, 14 are subsequently the other fractions such as paper 8 and plastic 7 separated.
- the separation of the different fractions using a suitable arrangement of suction and blowing nozzles or other conveyors can in many ways be made, however, are an accurate and reliable control of the sorting devices 10, 14 necessary, which in turn ensures rapid and reliable assignment the objects to the different fractions 11 or 12 conditionally.
- the inventive method is for this purpose in the Location.
- transmissive spectrometer systems which consists essentially of a lens 17, a Imaging Spectrograph 18 and a matrix detector 19 (e.g. a CCD camera) (see Fig. 4).
- a matrix detector 19 e.g. a CCD camera
- non-spatially resolved spectrometer must the Measuring head are moved over the object or the object be moved in different directions under the measuring head, nevertheless to provide locally differentiated spectral information receive.
- Spatial spectrometer systems here also as camera 5 or spectrometer 5 referred to measuring devices, the one simultaneous recording of spectral and local Information of an object surface allowed.
- the detection area 6 of the camera 5 is preferably line-by-line. or strip-shaped. This is done in a known manner achieves appropriate arrangement of lenses 17, the of the Object 7, 8, 9 emitted radiation on the entrance slot of the spectrograph 18.
- the length of the pictured Strip can range from a few millimeters to several Meters vary by either commercially available Microscope lenses or usual camera lenses used become. The spatial resolution varies accordingly Micrometers for measurements in the millimeter range up to several Millimeters for measurements in the meter range. Typically will the spectral image of a monochrome CCD camera 19 added.
- the location-dependent intensities for different wavelengths can thus be considered three-dimensional image are displayed. Every pixel corresponds to a specific location on the pictured strip of the object 7, 8, 9 and an intensity at a certain Wavelength.
- the spatial axis is in x direction and the spectral axis in the y direction of the detector 19 laid.
- the local resolution is then determined by the number of the pixels in the x direction, while the number of Wavelength bands by the number of pixels in y direction is determined.
- the matrix detector 19 usually a CCD camera, has prefers a uniform sensitivity over one the broadest possible wavelength range.
- CCD cameras 19 with such a characteristic at least in the visible Wavelength range are commercially available.
- the good ones Measuring characteristics of the ultraviolet and blue Wavelength range to the near infrared.
- NIR near infrared
- These Technology works up to a wavelength of 2500 nm.
- Transducer is preferred in these cases NIR area camera used.
- an FPA Fluor Plane Array
- InGaAs and thermoelectric cooling can be used.
- CCD cameras 19 therefore sometimes indicated to use multiple spectrometers 5 to the entire wavelength range from the near infrared to sometimes in the UV range, because different materials for the generation of evaluable spectra sometimes in different wavelength ranges are examined have to. In this case, however, material flows can be sorted which are composed of diverse fractions.
- CCD cameras are also CMOS, CID or "Diode array" cameras are conceivable, albeit at least currently available systems of this kind still significantly lower Have sensitivities as conventional CCD cameras.
- the conversion of analog to digital data can be done using conventional PC frame grabber cards with 8-bit digitization be made, but it is at more sophisticated sorting tasks proves beneficial, Resolutions from 12 to 16 bit to use.
- Alternatively can also be a conversion of the analog measurement signal into a digital signal, sometimes on PC frame grabber cards can also be dispensed with.
- the amount of data collected can vary depending on the desired local and spectral resolution can sometimes be considerable. It will therefore be the speed of data processing to optimize which through appropriate data preparation as well as special Evaluation algorithms can be achieved. It turns out but in practice as adequate, not the whole spectral information at each pixel of the measured Object strip to digitize and evaluate, but to be limited to selected wavelength ranges. This can significantly increase the amount of data to be processed be reduced and the conveying speed of the Sorting belt 1 can be increased. Will about the number of to be evaluated coordinate points of the matrix detector 19 to the Factor 10 reduces, as a rule, a reduction is shown the data processing times by a factor of 100.
- the required irradiation intensity with the aid of Radiation sources 3 depends in particular on the properties the camera optics, the camera sensitivity, the spectral Resolution, the integration time (ie the measuring time of a Strip, which depends on the conveying speed of the sorting belt 1), the f-number of the lens 17 and the Spectrograph 18 and the spatial dimensions of the Detection range 6 from. It's about as possible uniform illumination of the detection area 6. That can be about using fiber optic lamps or tungsten halogen lamps with linear parabolic or elliptical Reflectors 4 achieved with downstream cylindrical lenses become.
- the lighting using the radiation sources 3 should be there as stable as possible and over the whole Wavelength range of the emitted radiation uniform ("flat") emission spectrum. As with many commercially available CCD cameras sensitivity in blue wavelength range decreases, may be in the lighting be ensured by means of the radiation sources 3 also the intensity is stronger in the blue wavelength range.
- Halogen lamps provide about a very stable spectrum and have a relatively long lifetime but over weak emission in the blue wavelength range. With the aid of a red filter, the emission intensity can exceed the entire wavelength range but somewhat balanced become.
- Xenon lamps produce a very flat spectrum in the visible area, but more unstable than that of halogen lamps is and also requires one High voltage supply. Xenon flash lamps can as well be used. They have a long life and represent high-power radiation sources, but Variations in intensity of 1-2% as well as spectral Instabilities in the lightning can occur.
- the classifiers are capable of learning, i. it can be a variety of materials predefined, trained and then material classes be assigned. Based on the classified strip, the Moving the objects 7, 8, 9 in the conveying direction 2 of the Sorting tape 1 and the rapid repetition of the measurement This results in a classified image of the one to be recognized Object 7, 8, 9.
- This picture is about algorithms evaluated and according to the instructions of the user Passing or assigned to a Austragsfr hope. To the assignment will be at the end of the sorting belt 1 time and Locally correct air nozzles or suction nozzles 10, 14 depending on Sorting task activated. After activation of the The object is discharged via a separating roller, separating belt or separating edge 13 separated from the other material flow.
- the inventive method thus provides a comparatively simple process solution, not for every single separation phase (paper board, plastic paper, Plastic 1-plastic 2, etc.) a separate separator with radiation source, evaluation unit and discharge or Blowing device must be provided. Instead, over spatially resolved spectroscopy sufficient data material charged to make a reliable classification can. It is also possible when irradiated by only a radiation source 3 unique material properties according to which the individual political groups 11, 12 can be sorted out. So can also about the groupage Appearing impurities such as e.g. Foils, laminated Cardboard boxes, composite cartons, multilayer cardboard boxes with Metal or plastic films detected us to be sorted out.
- impurities such as e.g. Foils, laminated Cardboard boxes, composite cartons, multilayer cardboard boxes with Metal or plastic films detected us to be sorted out.
