Definitions
- the present invention relates to the characterization, and the case if necessary, automatic sorting of objects, in particular household packaging recyclable, according to their constituent materials and / or according to their color, the combination of a constituent material or substance and a color being called in the following a category.
- Its object is an inspection device and method automatic scrolling objects with characterization and discrimination in depending on their chemical composition.
- the machine according to the invention is particularly, but not limitatively, suitable for inspection, and if necessary for sorting, at high rate of different recyclable plastic packaging, including PET, HDPE, PVC, PP and PS bottles, as well as packaging paper / cardboard, composites (drink bricks) or metal.
- this machine can also be used for inspection and discrimination of all other objects or articles containing organic chemical compounds and scrolling with a substantially monolayer planar presentation, such as for example fruit (discrimination by sugar level), and discrimination can be produced on the basis of a majority or minority chemical compound, or of a plurality of chemical compounds.
- discrimination may lead to separation of the flow of objects by categorical sorting or simply by counting and characterization of said flow.
- Document EP-A-0 706 838 in the name of the applicant, presents a sorting machine and method suitable for flow objects Planar.
- This machine uses at least one machine vision system to locate objects, as well as to recognize their shape and color, a robotic arm for gripping and handling objects, and at minus a complementary sensor to recognize their constituent material.
- This complementary sensor is advantageously an infrared spectrometer.
- This system has the advantage of being in principle multi-material, since the main packaging is sorted by material, and / or by color, and they are distributed in a plurality of suitable bins. A single machine can thus sort up to eight different categories. Through elsewhere, the individual grip of the objects guarantees excellent quality sorting, typically a default for 1000 sorted objects.
- the sorting rate of this system is limited by the individual gripping of sorted objects and does not exceed 60 to 100 kg / h per sorting module.
- the only way to increase this rate is to stunt several identical sorting modules, which increases the overall size of the machine, as well as its cost price.
- Document US-A-5 260 576 presents a sorting machine planar emitting over the flux of electromagnetic radiation, received by transmission below the stream of objects.
- the intensity of these radiation makes it possible to distinguish materials according to their relative opacity in transmission. So when the radiation is X-ray, it document mentions a satisfactory separation of PVC, which contains a chlorine atom opaque to X-rays, compared to other plastics, which do not contain it, in particular PET.
- a row of nozzles ejects one of the object classes or not.
- Document EP-A- 0 776 257 describes a sorting machine planar broadband, and likely to recognize a material among many.
- the material to be recognized is chosen at the time of construction of the machine by a suitable, fixed calibration.
- near-infrared lighting is emitted on top and the sensor is also placed on top so that it analyzes the light backscattered vertically by the objects.
- the reception is done by means of a plane mirror or concave in a semicircle extending over the entire width of the mat, then polygonal rotating mirror. There is therefore a cyclical scanning of the measuring point across the width of the mat.
- the light received from the measuring point is then divided by a mounting of semi-reflecting mirrors in several streams. Each stream passes through an interference filter centered on a specific wavelength, then leads to a detector. Each detector therefore measures the proportion of the received light contained in the bandwidth of the filter. Analysis of relative intensities measured by the various detectors allows to decide if the material present at the point of measurement is or is not that which one seeks.
- the number of filters mentioned in this document is between 3 and 6.
- the detection algorithm must perform a reconstruction two-dimensional objects to be sorted before ejecting them, which assumes a relatively large distance between the detection zone and the ejection area, increasing the risk of erroneous ejection due to movement of objects between detection and ejection.
- WO 99/26734 presents a sorting machine high-speed planar, with an architecture fairly close to the document previous, but announces multi-material recognition.
- this document approaches the problem of the quantity of light: it offers a vision system in upstream on the infrared detection conveyor, quite system comparable to that mentioned in the aforementioned document EP-A-0 706 838.
- This system makes it possible to locate each object present, and allows, at the level infrared detection, to control by a set of mirrors positions a single measurement point which follows the scrolling object.
- Time available analysis becomes relatively long, around 3 to 10 ms, since we only analyze one point per object.
- Implementation although not specified, can then use a known technology compatible with this analysis time.
- document DE-A-1 96 09 916 describes a miniaturized spectrometer for a planar sorting machine for plastics, operating with a diffraction grating to spread the infrared spectrum on an output band, and a small number of sensors corresponding to wavelengths irregularly distributed in this output band. It is indicated in this document that one can be satisfied with ten well-chosen sensors, instead of the 256 sensors of a conventional photodiodes array. However, each of these ten sensors has an area equivalent to each sensor of a strip, typically a rectangle of 30 x 250 ⁇ m 2 . Such a surface collects little light and limits the analysis rate to 200 measurements / second. Such a spectrometer cannot therefore analyze all the points of a fast conveyor with the speeds and resolutions mentioned above.
- the main object of the present invention is to propose a machine and a method of inspection, and if necessary of sorting, operating at high speed and for substantially object flows monolayer, this machine and this process being capable of discriminating from reliably objects with significant heights, while making state of construction and implementation which remain simple and economic.
- the invention will have to overcome a vision system independent to locate objects, minimize the number of sensors necessary, maintain good reliability, especially in the event of sorting, when the objects move relative to the support which transports them and present a optimized operating efficiency of the radiation emitted.
- the superimposition of the lighting and scanning planes gives a good depth of field and their tilt by relation to the plane of the objects analyzed makes it possible to effectively eliminate the stray light constituted by specular reflection.
- the receiving device comprises a movable reflecting member carrying the input optical center, directly receiving the reflected radiation at the level of the sweeping elementary measurement area and having dimensions substantially of the same order of magnitude as the dimensions of said elementary measurement zone which it ensures movement, preferably slightly higher.
- the means of application consist of broad spectrum lighting means, applied radiation consisting of a mixture of electromagnetic radiation from the visible domain and the infrared range, and said lighting means include organs concentrating the emitted radiations, at the level of the plane of conveying, on a transverse detection strip swept periodically by the elementary measurement zone and whose longitudinal median axis corresponds to the detection line.
- the means for applying radiation are preferably consisting of two application units spaced apart and arranged in a transverse alignment with respect to the direction or direction of scrolling of the objects, each unit comprising an emission member elongated associated with a section shaped reflector member elliptical.
- each member elongated emission is substantially positioned at the level of the near hearth of the elliptical reflector associated therewith, the means of applying radiation being positioned and the reflectors being shaped and dimensioned in such a way that the second distant focus is located at a distance from the conveying plane corresponding substantially to the height average of the objects to be sorted.
- the receiving device is in the form of a head reception located at a distance above the conveying plane and carrying, part, a movable reflecting member in the form of a plane mirror (the the geometric center is advantageously substantially confused with the input optical center), arranged substantially centrally by relative to the conveyor plane and oscillating by pivoting with sufficient amplitude for the mobile elementary measurement area can explore the entire detection band during a half-oscillation and, on the other hand, a focusing means, for example under lens shape, of the fraction of radiation (s) reflected by a part elementary of the detection band and transmitted by the oscillating mirror in direction of said means, said head also carrying the end having the inlet opening of the means for transmitting said fraction of radiation (s), after focusing by the means, towards at least one spectral analysis device.
- a focusing means for example under lens shape
- the mobile elementary measurement zone which sweeps in a progressive the entire surface of the moving conveyor support, is defined, in combination, by the characteristics of the inlet opening means of transmission and the characteristics of the means of focusing, as well as their relative arrangement, the focusing means and the consecutive transmission means being located outside the field exploring the oscillating mirror (defined by its optical center or geometric), located in the scanning plane, the alignment axis mirror / focusing means / entry aperture being located in said plane containing said field.
- the fraction of detection or measurement surface reflected by the oscillating mirror will advantageously be at least slightly higher in area at the elementary measurement area, centered with respect to this last and the same shape or not.
- the oscillating plane mirror forming the member mobile reflective is located between the two units forming the means application of radiation and in a relative provision such as said units do not interfere with the field of exploration of said mirror.
- the mirror will preferably be located at a more distant large of the conveying plane that the units of the application means, under in the form of halogen lamps for example. However, it can also be arranged at the same height or even closer to this plane than said units, without affecting the efficiency of the detection station.
- the means of transmission preferably consist of a bundle of fibers 10 "optics, all or most of which are connected to a device analysis breaking down the reflected radiation into its different spectral components and determining the intensities of some of said components having wavelengths characteristic of the materials of objects to be sorted, and a minority of which can be advantageously linked to a analysis device detecting the respective intensities of the three colors fundamental, said optical fibers having at the opening input a square or rectangular arrangement in section.
- a first analysis device consists, on the one hand, of a spectrometer with diffraction grating decomposing the multispectral light flux received from the elementary measurement area in its different spectral components constitutive, notably in the infrared domain, on the other hand, by means for recovering and transmitting light fluxes elementary corresponding to different spectral ranges irregularly spaced apart characterizing the chemical substances and compounds of objects to discriminate, for example in the form of fiber optic bundles separated, and finally by photoelectric conversion means delivering an analog signal for each of said elementary light fluxes.
- Multispectral light flux from the measurement area elementary is introduced into the spectrometer at an entry slit and the elementary luminous fluxes are recovered at the level of slits of outlet having a shape and dimensions identical to those of the slot input and positioned according to the dispersion factor and ranges spectral to be recovered, the output end portions of the fibers of the majority component of the fiber bundle forming the means of transmission and the input end portions of the optical fibers of the recovery and transmission means with arrangements identical linear and being mounted respectively in the entry slit and the exit slots.
- the input end portions of the optical fibers of the bundles forming the recovery and transmission means are mounted in thin plates provided with suitable receiving recesses, preferably associated with retaining and locking, so as to form mounting and positioning supports said optical fibers in the body of the spectrometer.
- the body of the spectrometer comprises a rigid receiving and holding structure with blocking of said supports, authorizing their installation by sliding and their installation by stacking, with possibly interleaving of adjusted shims, so as to position said supports at the locations corresponding to the zones impact of elementary light fluxes to be noted.
- Such an arrangement allows rapid, easy and Accurate inspection machine to detect groups of materials different, characterized by groups of wavelength ranges specific, depending on the type of objects and the selectivity to operate.
- the first spectral analysis device is therefore mainly consisting of a means allowing light to be distributed without significant losses according to its constituent wavelengths, as well as a small number of detectors (10 to 20) in the form of conversion means photoelectric with high unit area, each of these detectors being specific to a wavelength range (PLO), these PLOs being suitably chosen for robust and simultaneous identification of several chemical substances or compounds, corresponding for example to several materials.
- PLO wavelength range
- a second analysis device carrying out the color recognition of objects is associated with the previous device by taking a small part of the light flux from the fiber bundle to route it to three sensors each sensitive to one of the colors fundamental, ie Red, Green, or Blue.
- the latter also includes a processing and operating management of the detection station, such as a computer controlling in particular the movement of the reflecting organ mobile and possibly the conveyor, sequencing the acquisition of reflected radiation at the level of the mobile elementary measurement area and processing and evaluating the signals delivered by the analysis devices, by example by comparison with programmed data, with a view to determination of the chemical composition of each object inspected or the presence of a chemical substance in said objects, while correlating the results of said determination with a determination of the spatial location of said objects.
- a processing and operating management of the detection station such as a computer controlling in particular the movement of the reflecting organ mobile and possibly the conveyor, sequencing the acquisition of reflected radiation at the level of the mobile elementary measurement area and processing and evaluating the signals delivered by the analysis devices, by example by comparison with programmed data, with a view to determination of the chemical composition of each object inspected or the presence of a chemical substance in said objects, while correlating the results of said determination with a determination of the spatial location of said objects.
- the detection strip is in the form of an elongated rectangular surface of small width extending perpendicular to the median axis and transversely across the width the conveyor plan, for example in the form of a belt or strip whose upper surface coincides with said plane of conveying.
- the distance detection-discrimination can be limited to approximately 100 mm, which minimizes the probability that an unstable object on the mat will move before his discrimination, resulting for example in his evacuation.
- the invention also relates to an automatic sorting machine. of objects according to their chemical composition, these objects scrolling so substantially monolayer on a conveyor, this sorting machine comprising an upstream detection station functionally coupled to a downstream station for active separation of said objects according to the results of measurements and / or analyzes carried out by said detection station, characterized in that the detection station is a detection station as described above.
- the detection station delivers signals actuation to a module for controlling the ejection means, transverse alignment of the active separation station according to the results of said analyzes, a burst of actuation signals being emitted after each complete exploration of a transverse detection strip by the mobile elementary measurement zone.
- the detection line is located near immediate (for example within 30 cm) of the ejection means, by example by lifting, in the form of a row of nozzles delivering gas jets, preferably air.
- said method consists in particular in concentrating the radiation, preferably in the visible and infrared range, at the plane of conveying on a transverse detection strip swept periodically by the elementary measurement zone and whose longitudinal median axis corresponds to the detection line, so as to obtain an intensity of high and substantially homogeneous radiation over the entire surface of said detection band.
- said method can consist in sweeping sequentially the detection band with the elementary measurement zone movable by pivoting oscillation of a plane mirror forming the organ reflective, to focus the light flux coming from the measurement area elementary on the inlet opening of the transmission means in the form of a bundle of optical fibers, to bring the majority of the luminous flux multispectral sensed towards the entry slit of a spectrometer forming part a first means of analysis, to decompose this luminous flux into its different elementary spectral components, to recover fluxes of some of these components corresponding to ranges of specific narrow wavelengths at and at exit slits transmit through means adapted to means of photoelectric conversion to provide first measurement signals, to bring, if necessary, simultaneously a small part of the luminous flux multispectral captured towards a second means of analysis determining the respective intensities of the three basic colors and providing second measurement signals, to process said first and possible second measurement signals, at the level of a processing and management unit IT controlling in particular the movement of the organ mobile reflective, sequencing the acquisition of radiation reflected
- the inspection process When the inspection process is implemented in relation with a sorting machine as described above, it can also consist to be delivered by the processing and management unit, depending on the results of processing measurement signals, actuation signals to a control module for ejecting means from a separation station located downstream of the detection station in relation to the flow of objects, and, finally, to eject or not to eject each of the different objects scrolling on the support plane conveyor conveyor according to actuation signals issued.
- a burst of actuation signals is emitted after completion of each scan of the detection and processing strip corresponding measurement signals, if applicable with consideration measurement signals from the previous scan.
- the radiation emitted is concentrated in the vicinity of the lighting plane Pe and said lighting plane Pe and the scanning plane Pb are combined, this common plane Pe, Pb being inclined with respect to the perpendicular D to the conveying plane Pc. This last provision allows in particular to get rid of specular reflection.
- transverse in relation to the detection line 7, we means an extension over the entire width of the defined conveying plane Pe by the conveyor 3 ce, preferably but not limited to, straight and perpendicular to the direction of travel of objects 2.
- the conveyor plane Pc will correspond for a support of flat conveying on the surface of the latter and for non-planar supports, such as buckets mounted on chains (for individualized transport, for example for fruits), to a median plane characterizing the scrolling of said objects.
- the detection station 4 is identical for these two machines, the sorting machine additionally comprising a separation station 5.
- Figure 1 shows the general structure of the sorting machine 1 automatic by chemical composition or material.
- Objects 2 arrive in fast scrolling (2 to 3 m / s) on a conveyor or conveyor 3 so that they are substantially spread over a single layer.
- the surface of conveyor 3 is dark, and its constituent material (in general of matt black rubber) is chosen different from the materials or compounds chemicals to recognize.
- This region is substantially demarcated by broad spectrum lighting means 6 (visible and infrared), which concentrate the light flux through 6 'reflectors, strongly illuminate an area 7 'in the form of a narrow detection strip effective, the width of which is 25 to 40 mm.
- broad spectrum lighting means 6 visible and infrared
- Zone 7 ' is analyzed at high speed using a mirror oscillating 8 ', controlled by a computer 23, and which cyclically directs the measurement towards each of the elementary elementary zones 12 'of the zone 7'.
- a full scan cycle of area 7 ' takes approximately 8 ms.
- the conveyor 3 has advanced a distance substantially equal to the width of said zone 7 ′, so that there is no detection “hole”: any point of the conveyor 3, or of the moving conveyor plane Pc, is analyzed.
- Bundle 10 is subdivided into two parts: the first brings the majority of the luminous flux to a spectrometer 14, forming part of a first analysis device 11 and subdividing this part of flux according to its constituent wavelengths in the field near infrared (NIR).
- NIR near infrared
- a small number n of PLOs (Length Ranges selected) is sent to a module containing conversion means 16 in the form of surface NIR photodiodes high unit, and an amplification stage. This module converts signals bright in as many analog electrical signals, which are then analyzed by the computer 23.
- the second part of the bundle 10 is brought to a second analysis device 11 'corresponding to a color detection module.
- This module allows to isolate the Red, Green and Blue components by filtering, then convert the light signals into electrical signals and amplify. After conversion, the output signals are also analyzed by computer 23.
- a first decisive advantage of the machine 1 is that the reflected light receiving device (8 'mirror and 9 lens assembly) does not physically extend over the entire width of the conveying plane Pc corresponding for example to the surface of a conveyor belt 3, but is unique and implanted only at the center of the midline of the conveyor 3. This avoids inhomogeneities between different points of reception which would interfere with the uniformity of the signal across the 7 'detection.
- a second determining advantage of the geometry of the machine 1 is that the detection zone is placed as close as possible to the row 5 'ejection nozzles.
- the detection-ejection distance d can be limited, with suitable IT resources, approximately 100 mm, which minimizes the probability that an unstable object on the carpet will move before it ejection. It is only limited by the software processing time, which is very fast since it relates to information from a single line of measures, or even two contiguous lines only. This distance is significantly lower than that existing in planar flow machines known previously described.
- the aim is to bring a maximum of light onto the detection zone 7 ′ with the constraint of keeping the lamps far enough from the objects 2 in circulation to allow these objects to circulate without interference.
- the quantity of light is roughly evaluated in electrical W / cm 2 , knowing that we are referring to a halogen lamp with a color temperature of 3400 K.
- the manufacturing of the 6 'reflectors must be very precise for a good operation, but it is easier than that of conventional reflectors circular symmetry, like parabolic mirrors.
- a surface developable which can be produced by folding.
- the inventors have determined that the best intensity distribution is obtained using only two 6 'reflectors quite long, separated by a vacuum as shown in Figure 3.
- the average density obtained is 2 x 1000 / (80 X 4) ⁇ 6 W / cm 2 , or about 60 times more than the sun in broad daylight.
- Such a concentration is only compatible with a carpet 3 in rapid movement to avoid burning it.
- Electrical safety devices are provided to automatically switch off the lighting in the event of the carpet being stopped.
- the aim is to analyze around 40 to 80 surfaces within the 7 'zone by means of an elementary zone of measure 12 mobile.
- These elementary surfaces 12 ′ have a shape rectangular, with dimensions from 10 x 20 mm to 20 x 20 mm.
- such an elementary surface 12 ′ is called a "Pixel", all of said pixels corresponding to the detection area 7 '.
- the inventors chose a mobile mount that sequentially scans all the pixels. A single sensor then allows all the measurements, provided that the measurement is carried out very quickly.
- the preferred solution is an 8 '30 mm oscillating mirror diameter, mounted in a detection head 8 and which oscillates with a angular amplitude c between the positions shown in Figure 4A.
- the instantaneous delta angle (figure 4C)
- it returns the light from a pixel 12 'towards the fixed lens 9 which focuses it in a bundle 10 of fibers 10 "optics, the 12 ′ pixel has been represented as a point for readability of figures 4.
- angles of light return non vertical are accepted. Choose a height of the mirror 8 ' large enough to limit the angle b of the field of exploration C to a value slightly lower than 60 °. From experience, faults geometrical sights remain acceptable for these angles. Like any variation of angle ⁇ of a rotating mirror results in a variation of 2. ⁇ from the position of the reflected beam, the plane mirror can then oscillate on a half angle, 30 ° in all.
- the lens 9 is arranged as much as possible under the mirror 8 ', without interfere with the field of exploration C (angle b). Nor should it be too low above the conveyor belt 3.
- Lighting design with an empty space in the center above of carpet 3 is used to make the oscillation plane coincide or scanning Pb of the mirror 8 '(including the scanning field C) with the lighting plane Pe (plane containing the focal points F and F 'and passing through the axis median of the detection zone 7 '.
- the measurement area (angle b) does not interfere with 6 "tubes or 6 'reflectors.
- This design is very advantageous for analyzing objects 2 significant height (up to 200 mm high), because whatever the height of the object, the illuminated area and the analyzed area coincide.
- the lighting and the measurement spot are no longer focused, detection remains reliable despite a decrease in pixel sharpness, because the brightness remains substantially identical. Indeed, the lighting disperses well on one more large surface, but at the same time the object approaches the halogen tube and therefore receives a larger direct flux, and the mirror / object distance decreases, which increases the density received on the mirror 8 '.
- the common plane (lighting plane Pe and scanning plane Pb) of lighting means 6 and the oscillating mirror 8 ' is inclined at an angle alpha by vertical to the conveying plane Pc.
- This gamma angle must be at least 5 °, and preferably greater than 10 ° for good safety (see figure 2 of the accompanying drawings).
- the lens 9 serves to limit the size of the pixel 12 'analyzed, even at great distance from the conveyor belt 3.
- the light flux received is optimal.
- it is almost independent of the mirror-conveyor distance, and that it is identical to the flux picked up by a bundle of fibers of the same surface, placed near the conveyor and under the same illumination, and without any optics.
- FIGS. 5 and 6 of attached drawings The following description is based on FIGS. 5 and 6 of attached drawings.
- a dispersion which is the ratio between the wavelength changes expressed in nm, and the distance over the exit slit, expressed in mm.
- the inventors have chosen a dispersion of between 20 nm / mm and 30 nm / mm.
- the bundle of optical fibers 10 makes it possible to transport the reflected light received from pixel 12 '(14 "multispectral light flux) from the square section end carrying the opening 10 ', of form identical to the pixel, towards the entry slot 17 of the spectrometer 14, where the fibers are rearranged according to a fine vertical 17 'slot.
- the image of the input slot 17 for each PLO chosen at the network output 14 ' is a slot 17' of the same shape and same dimensions as at the input.
- the various elementary light fluxes 14 "′ corresponding to the various PLOs are collected by exit slots 17 ′.
- a network of fiber bundles 15 ′ is provided at this level forming reception and transmission means 15 and these fibers are rearranged at the other end in 15 "circles, each of which is fixed in contact with a photodiode 16 of InGaAs, with an active surface of approximately 1 mm 2 .
- the spectral width of the PLOs is fixed, and is approximately 5 nm, which makes it possible to use identical photodiodes.
- beams 15 of different sections, associated with photodiodes 16 of corresponding surface for example a spectral width of 10 nm with two rows of contiguous optical fibers, for a photodiode surface of approximately 2 mm 2 ). It is thus possible, as desired, to increase the luminous flux received, or to refine the resolution.
- the amount of light is divided only once: if we double the number of output beams, each of them will have as much light as in the original montage.
- a rearrangement of the PLOs then consists simply in removing ferrules 18, 19 and shims 22 of the holding box 21, then to be replaced some shims by those of different dimensions, and finally to put them back in the case.
- the operation is easy, fast (only one work session), and reversible.
- the photodiodes of the conversion means 16 provide a intensity proportional to the number of incident photons over the entire their surface for a given time. This current is converted into voltage and amplified before delivery to computer 23.
- the inventors preferred the first implementation, which is the simpler and less restrictive for the computer system of treatment 23.
- the active surface of the photodiodes 16 used in fact dimensions the entire design of the recovery / transmission / analysis assembly. Indeed, there is no point in producing an output beam 15 from the diffraction grating 14 'which is larger than the surface of the associated diode 16: the additional surface would not be used. Similarly, the laws of optics require that the dimensions of the inlet slot 17 of the network 14 'are the same as the dimensions of the outlet slot 17'. As for the optical fiber bundle 10, it obviously keeps the active surface unchanged, that is to say about 1 mm 2 .
- the flux received on the inlet opening end 10 ′ of this beam only depends on its surface, and on the intensity of illumination at the level of the conveying plane Pc (for example surface conveyor belt 3), subject to proper sizing of the optical assembly 8 'and 9.
- Figure 5 in relation to Figures 1, illustrates a possible embodiment of the second analysis device 11 '(color analysis).
- This second device 11 ′ could also be produced at by means of a diffraction grating.
- the photodiodes 27 associated with the aforementioned filters are in Silicon and cover the whole visible area: this material is very good market and has very good detectivity, about 100 times higher than InGaAs in the infrared. Thanks to this high sensitivity, there is no need to bring a bundle of fibers in front of the diode: a single fiber of diameter 200 ⁇ m gives a sufficient signal.
- the end with the inlet opening 10 ′ can thus comprise approximately twenty fibers, of which sixteen or seventeen are found at the end entering the entry slit 17 of the spectrometer 14, three of which enter the analysis device 11 'or color module. Given the amount of visible light available, we can even consider using a single fiber for color and spreading its light on three filters: this leaves a maximum of sensitive surface for the part of the beam 10 connected to the spectrometer 14.
- an amplification stage conventional, not shown, allows analog signals to be brought to a sufficient level to acquire them on the computer 23.

Abstract
Description
- individualisation complète avec un seul objet par réceptacle, sans saisie d'objet ;
- flux filaire, les objets étant alignés les uns derrière les autres ;
- flux planaire, les objets étant étalés en vrac sur un tapis nettement plus large que leur plus grande dimension, et répartis sur une seule couche.
- L'individualisation complète n'a jamais fait ses preuves industriellement. Les prototypes mis au point avec ce mode de présentation ont tous cessé de fonctionner depuis.
- Le flux filaire existait déjà dans les machines de sur-tri industrie dans lesquelles le flux principal était homogène, et le sur-tri consistait à retirer un faible pourcentage d'objets indésirables. Appliqués à un flux hétérogène d'emballages, des systèmes filaires ont fonctionné sur des flux particulièrement propres. Cependant, ces machines sont limitées en débit et nécessitent en amont de la machine la présence d'opérateurs manuels pour retirer les objets susceptibles de perturber le fonctionnement, notamment les grandes feuilles plastiques et les gros contenants. Ils ne constituent donc pas une solution satisfaisante d'automatisation du tri, et ont eu peu de succès.
- Au contraire, les flux planaires ont fait leurs preuves, puisqu'il s'agit exactement de la présentation des objets que l'on rencontre en tri manuel. On sait donc la réaliser simplement dans un contexte de déchets ménagers, et les machines utilisant ce type de flux sont adaptées aux conditions de tri en vrac et connaissant un succès nettement supérieur aux deux autres types précités.
- l'algorithme de détection doit être assez simple (donc peu d'opérations et traitement grossier) pour être effectué en temps réel ;
- l'électronique de réception doit être très rapide ;
- la quantité de lumière reçue doit être suffisante dans un temps très bref.
- une reconnaissance multimatériaux imposerait d'utiliser non pas 3 à 6 plages de longueurs d'onde (ou PLO), mais au moins 8 à 16 ;
- de plus, les largeurs des PLO, relativement importantes dans l'exemple cité (32 à 114 nm), devraient être réduites dans une gamme de 5 à 20 nm, puisqu'un plus grand nombre de PLO doit être distingué dans la même largeur spectrale.
- elle nécessite un matériel supplémentaire, à savoir un système de vision ;
- elle impose le choix par vision du point de mesure spectrométrique sur l'objet, ce qui peut être délicat en présence d'étiquettes ou de salissures ;
- elle suppose l'immobilité de l'objet sur le tapis : les deux détections s'effectuant sur des zones d'environ 1 m x 1m, l'objet se déplace de 1 m au moins entre sa détection par vision et sa détection par spectrométrie, puis de 0,5 m en moyenne entre sa détection par spectrométrie et son éjection finale. Or, l'immobilité n'est pas du tout assurée lorsque le convoyeur avance à 2,5 m/s, surtout lorsque les objets sont des bouteilles susceptibles de rouler.
- des moyens d'application de rayonnements électromagnétiques en direction du plan de convoyage, émettant lesdits rayonnements de manière à définir un plan d'éclairage, l'intersection dudit plan d'éclairage et dudit plan de convoyage définissant une ligne de détection s'étendant transversalement au sens de défilement des objets pour la largeur du flux convoyé,
- un dispositif de réception permettant de balayer périodiquement tout point de ladite ligne de détection, et recevant à tout instant les rayonnements réfléchis par une zone de mesure élémentaire située au voisinage du point balayé à cet instant, le plan défini par ladite ligne de détection et le centre optique d'entrée dudit dispositif étant appelé plan de balayage,
- des moyens de transmission à au moins un dispositif d'analyse desdits rayonnements réfléchis au niveau de la zone de mesure élémentaire balayante,

- à balayer périodiquement tout point de ladite ligne de détection par l'intermédiaire d'un dispositif de réception recevant à tout instant les rayonnements réfléchis par une zone de mesure élémentaire située au voisinage du point balayé à cet instant, le plan défini par ladite ligne de détection et le centre optique d'entrée dudit dispositif étant appelé plan de balayage,
- à transmettre lesdits rayonnements réfléchis au niveau de la zone de mesure élémentaire balayante à au moins un dispositif d'analyse par l'intermédiaire de moyens de transmission adaptés,
- des moyens 6 d'application de rayonnements électromagnétiques en direction du plan de convoyage Pc du convoyeur 3, émettant lesdits rayonnements de manière à définir un plan d'éclairage Pe, l'intersection dudit plan d'éclairage Pe et dudit plan de convoyage Pc définissant une ligne de détection 7 s'étendant transversalement au sens de défilement des objets 2,
- un dispositif 8 de réception permettant de balayer périodiquement tout point de ladite ligne de détection 7, et recevant à tout instant les rayonnements réfléchis par une zone de mesure élémentaire 12 située au voisinage du point balayé à cet instant, le plan défini par ladite ligne de détection 7 et le centre optique d'entrée 8" dudit dispositif 8 étant appelé plan de balayage Pb,

- les faisceaux de fibres 15 sont munies de férules rectangulaires usinées avec précision, réalisées en deux pièces 18 et 19. Il est ainsi facile de les manipuler sans les briser. Une telle férule est formée d'une première plaquette 18 avec un renfoncement 18' renfermant avec blocage les extrémités des fibres optiques 15' et fermé par une contre-plaquette 19.
- L'espacement minimum des férules définit la résolution du système (figure 8), c'est à dire l'écart minimal entre deux PLO : il est donné par l'encombrement de ces férules. A l'extrême, on peut supprimer la plaque de protection ou contre-plaquette 19 d'une des deux férules, ce qui donne un écart en longueur d'onde de 10 nm (Figure 8).
- Pour choisir un positionnement arbitraire des férules dans la zone de sortie du réseau 14', on utilise un jeu de cales 22, usinées avec une rande précision (environ +/- 0,15 µm de tolérance). Par exemple, une cale de 5000 µm, et une cale de 280 µm, permettent de réaliser un espacement de 5280 µm.
