Ella concerna plus réciséme t um tabla da tri utilisable pour l'élimination da corps étrangers restant mélangés i ur» rêooie da fruits au â une vendange.  Ella concerned more recisame t um tabla da tri usable for the elimination of foreign bodies remaining mixed with a roo da da fruit at a harvest.
Une tal a tabla da tri permet notamment da séparer d'une part daa taies de raisin at d'autre part des feuilles, des pétioles ou daa débris plus volumineux ou plus0 allongés que las baies de raisin {feuilles, sarments, pétioles, rafles,„,). Il s'agit de débris susceptibles de sa trouver dens une vendange et an particulier d'une vendange a ant subi une opération d'égrappage,  In particular, a sorting table makes it possible to separate, on the one hand, grape pea and on the other hand leaves, petioles or debris which are larger or longer than berries of grapes (leaves, branches, petioles, stems, "). This is debris likely to find in a harvest and especially a vintage having undergone a destacking operation,
Da manière plus générale, l'Invention peut tre mise en m m pour l'élimination de débris susceptibles de sa trouver dans une résulte de fruits, at en particulier des patte fnjfts tels que des grœellles, du cassis, des mûres, des framboises, des olives, des asnnebergas, des airelles eu encore d'autres baies ou drupes.  In a more general way, the invention can be put in mm for the elimination of debris likely to be found in a result of fruits, and in particular legs fnjfts such as grêellles, cassis, blackberries, raspberries, olives, asnnebergas, cranberries, and other berries or drupes.

However, when the sieve is too weak, the rollers are too slow or the spill rate is too high to cause fruit arriving at the outlet end of the table to be discarded. mm debris, conversely, too much spacing between the rollers or a rotation speed too low favor an unwanted passage of debris through the sorting table, with the fruit,

E.iposé de f Ir erîtlen E.Issue of Dr. Iritlen
Linvantlon résulte de l'identification d'un certain nombre de problèmes techni ues tenant au réglage de la table da tri Un premi r problème as! qu'un réglage optimal da la table da tri ne tient généralement pas compta de la var ation de la qualité ou de la quantité da vendange à trier, La variation da la qualité s!entend oomma une variation da la tailla des fruits eu das baies ou encore oom a une variation du nombre et du type da débris mêlés aux fuite. A titre d'exem le, lors d'un tr! d'une vendange, une variation de la qualité peut tenir au cépage des raisins de le vendange* Elle peut aussi tenir à la parcelle» votre à une portion da parcelle, de provenance des raisins de la vendange à trier. Enfin, la variation da la qualité sa con tat aussi antre une vendange Intègre et une vendange avec des bêles écrasées eu altérées, Linvantlon results from the identification of a number of technical problems relating to the adjustment of the table. A first problem as! that an optimal setting of the sorting table does not generally take into account the variation of the quality or the quantity of the crop to be sorted, the variation in the quality of the quality of the crop . This is understood to mean a variation in the size of the fruits in the bays or even in a variation in the number and type of debris mixed with the leaks. As an example, during a tr! From a vintage, a variation of the quality can hold to the grape variety of the grape harvest * It can also hold to the parcel » your to a portion da parcel, from source of the grapes of the vintage to be sorted. Finally, the variation in the quality is also a result of an integrated grape harvest and a harvest with crushed, altered berries.
La variation da la quantité s'entend somme une variation du débit des truite ou des biles i l'entrée de la tabla de tri. Elle peut être liée ux variations de quantité de grappes da raisin récoltées mécaniquement par une machine à vendanger. Elle peut aussi être lléa aux variations de débit de fruits en provenance d'un dispositif d!allmentetlon d'une table de tri utilisée en chai. Variation in quantity means a variation in the flow of trout or bile at the entrance of the sorting table. It may be related to variations in the amount of grapes grapes mechanically harvested by a harvesting machine. It can also be linked to variations in fruit flow from a device d ! allmentetlon of a sorting table used in chai.
Une autre difficulté est liée é l'évaluation permanente du bon réglage de la table de tri et de la détection précoce d'un réglage Inadéquat En effet, le constat tardif d'une concentration trop élevée de débris dans las fruits triés ou au contraire la présence de Imita dans tes débris mis m rebut entraine une parte qualitative et ou quentitatlv sur les fruits triés.  Another difficulty is related to the permanent evaluation of the good setting of the sorting table and the early detection of an inadequate adjustment. Indeed, the late finding of a too high concentration of debris in the sorted fruits or on the contrary the The presence of Imita in the debris put aside leads to a qualitative part or quititatlv on the sorted fruits.
La présente Invention a ainsi pour but da proposer une table de tri pour irolte qui na présente pas les difficultés mentionnées ol lessus» The present invention is thus intended to provide a sorting table for irolte which does not have the mentioned difficulties ol lessus »
Un but est an particulier de proposer une table de tri adaptative avec une capacité d'évaluation da l'adéquation des réglages avec la récoite à trier, et une capacité d'ajustage des paramétres de tri, au cours d'une opération de tri, sans Interrompre le fonctionnement de la table da tri. Four atteindra sas buts, ïïrmnMùn proposa lus précisément ont table a tri pour truffe comprenant : A particular aim is to propose an adaptive sorting table with an ability to evaluate the adequacy of the settings with the pick to be sorted, and an ability to adjust the sorting parameters, during a sorting operation. without interrupting the operation of the sorting table. Oven will reach its goals, but it was precisely proposed to have a truffle sorting table comprising:

Comme Indiqué dans la partie inirodycilm les termes "fruit" ou *rtote* s'entendent sans limitation puant â la nature des fruits ou de la récolte et englobant ainsi également une vendange da relslnss ou dee raisins égreppés.. As Indicated in part inirodycilm the terms "fruit" or * * rtote are without stinking limit â nature fruit or harvest and thus also encompassing relslns da dee s harvest or égreppés grapes ..
Le terme "récolta* est entendu comme yn mélange de fruits et de débris non souhaités, mélangés eux frutîB au moment de leur collecte.. Les débris peuvent comporter des feuillages, de petites branchas, des pétioles, des refies, ou d'autre» corps étrangers.. La mm «fadmtafa du convoyeur est une par e du convoyeur sur l quelle est déversée le récolte, Elle est de préférence située à Tentée du envo ur. Une trémie ou un autre mécanisme de déversoir peut être révu au-dessus de la mm d'admission pour approvisionner le œnvoyeur et pour y répartir la récolte à trier, La mm de décharge de la table de tri eit située de préférer» an une sortie du convoyeur, Elle aa trouve m aval da la zone d'admission par rapport à une directe) de œnvo ge, La mm de décharge reçoit les débns qui n'ont pas traversé le orlble de la table de tri, da manière à les éliminer ou à las valoriser sépareraient, The term "reaped * is understood as yn mixture of fruits and unwanted debris, mixed them frutîB at the time of collection .. Debris may include leaves, small branchas, petioles, refies, or else" foreign bodies.. The conveyor belt is a conveyor belt on which the crop is dumped. It is preferably located at the bottom of the conveyor. A hopper or other weir mechanism can be seen above the inlet mm to supply the laborer and to distribute the crop to be sorted. The discharge mm of the sorting table is preferably used for an exit. From the conveyor, it is found downstream of the intake zone with respect to a direct discharge. The discharge mm receives the outlets which have not passed through the ort of the sorting table, so as to eliminate them. or to valorize them would separate,
Le onbie s'étend dans le pian de convoyage entre la icne d'admission et la zona da décharge. Ainsi le convoyeur fait passer la récolte au-dessus du srfble. Le longueur du crible peut être égale ou Inférieure à le distance séparent le sm d'admission et le zone de décharge.The onbie extends in the conveyor plane between the intake icon and the discharge zone. Thus the conveyor passes the crop over the srfble. The length of the screen may be equal to or less than the distance between the inlet sm and the discharge zone.
l convient de préciser u'une partie du son voyeur peut former directement le crible. Ceci est le cas lorsque le convoyeur comprend des rouleaux trieurs destinée i convoyer la réoolte. De tels rouleaux trieurs présentent entre eux des eapaoemente qui oonitltuent les ouvertures du orlble,  It should be pointed out that a part of the voyeur sound can directly form the screen. This is the case when the conveyor comprises sorter rollers for conveying the reool. Such sorting rollers have between them, which provide the openings of the hole,
Les fruits qui t av rsa t les ouvertures du crible sont soustraits de la récolte convoyée selon le plan da convoyage, lis sont recueils au-dessous du crible, c'est à dire sous le plan de'convoyage. Fruits that t av rsa t the apertures of the sieve are subtracted from the crop conveyed by da conveying plane, lily are collections below the sieve, i.e. below the plane of 'conveying.
Le plan de conv yage peut être de préférer» un plan sensiblement ortonfel I! peut aussi être Incliné par rapport à fhcntontele comme si ressort de la suite de la oascnp son,  The convoy plan may be to prefer a substantially ortonfel I! can also be inclined in relation to fhcntontele as if springing from the continuation of the oascnp sound,
Le dispositif de mesure de la quantité ou du débit de fruit traversant le crible ne mesure pas la quantité ou le débit total de initie mais est limité à une partie seulement du cribla.. Cette partie est désignée par "tronçon da référence* The device for measuring the quantity or flow rate of fruit passing through the screen does not measure the quantity or the total rate of initiation but is limited to only a part of the screen. This part is referred to as "reference section" .
Des mesures peuvent être effectuées sur plusieurs tronçons de référer» se succédant le long du crible selon un exe de eonvoyage, Chaque tronçon de référence peut dans ce cas, comporter un dispositif da mesura qui lui est propre, Les signaux des différents dispositifs de mesure, ou les signaux des capteurs qu'ils comportent peuvent alore être combinée pour rétablissement de commandes d'ajustage da la table de tri. En particulier, la mise en œuvra de deux fronçons de référence peut être avantageuse pour un réglage optimal du crible d'une table da tn susceptible da recevoir à 1a fois des vendanges Intégras at das vendages écrasées ou altérées. L'usage da deux tronçons da référence ennel da comparer 4 m oe oaa ta débits de baies de raisin trawre nt la crible an début at an fin de table da tri, par eienipls, Measurements can be carried out on several reference sections' succeeding one another along the screen according to a cleaning exe. Each reference section can in this case include a measuring device of its own, the signals of the different measuring devices, or the signals of the sensors which they comprise may also be combined for restoration of adjustment commands in the sorting table. In particular, the implementation of two reference frontiers can be advantageous for an optimal setting of the screen a table da tn likely to receive at once harvest Integraras and das crushed or altered sales. The use of two reference sections in comparison to 4 m oe oaa the grape berry flow trawre the sieve at the beginning and at the end of the table da sort, by eienipls,
s Dana un aoûts! da simplification, un seul tronçon da référence ait mentionné dans la suite da la description, sans toutefois préjuger du nombre de fronçons de nlférenee m s an mwm pour la table da tri.  s Dana an austere! In simplification, only one reference section has been mentioned in the remainder of the description, without, however, prejudging the number of reference fringes mwm for the sorting table.
La quantité de fruits au la débit da fruits traversant le cribla sur la tronçon da 10 référence est utilisée pour évaluer la quantité da fruits susceptible d'atteindre la zone de décharge à ra>drérn!té du convoyeur, The amount of fruit at the fruit rate passing through the screen on the reference section is used to evaluate the amount of fruit likely to reach the discharge zone at the conveyor's level.
La tronçon da référence est situé I dfstenc» da la zone d'admission du convoyeur. De préférence, Il peut être situé la plut pris possible de fartémité du cribla tournée van la mm de d cha ge. En état si une quantité da trolls importante t$ traverse le orlble sur son tronçon de référera», et si oe tronçon est proche de l'extrémité du crible, on peut estimer qu'une partie Importante des fruits de la vendange n'a as été sélectionnée avant la tronçon da référence at risque d'atteindre le zo a da décharge,  The reference section is located in the intake zone of the conveyor. Preferably, it can be located as much as possible from the screen of the screen to the table of the month. In condition if a significant amount of trolls passes through the bed on its reference section, and if this section is close to the end of the sieve, it can be considered that an important part of the fruits of the harvest does not have was selected before the reference section at risk of reaching the discharge zone,
inv raan ant, al très peu da fruits ou aucun fwft ne traverse le tronçon de référer»0 du crible, on peut estimer qua l'ensemble des tylts a déjà été trié avant d'atteindre le tronçon de référence et qua la partie restante du crible risque inutilement da faire passer da mani re non souhaitée des débris dena les fruits triés.  In the case of very little fruit where no fwft crosses the reference section of the screen, we can estimate that all the tylts have already been sorted before reaching the reference section and that the remaining part of the The sieve may needlessly pass unwanted debris out of the sorted fruit.
Le mesure du dispositif de mesura peut porter sur une quantité de truite absolue traversant la tronçon de référence du orlb!as par exemple lors du traitement d'un lot5 da récolte» Toutefois, et de préférence le dispositif peut ausal être configuré pour mesurer un débit ou un flux c'est-à-dire une quantité de fruits traversent la tronçon da référença par unité de temps, Measurement of the measuring device can relate to a quantity of trout absolute crossing the reference section of the orlb! S s for example during the treatment of a lot5 da harvest "However, and preferably the device can ausal be configured to measure a flow rate or a flow, that is to say a quantity of fruits pass through the section da referença per unit of time,
. Comme Indiqué précédemment la dispositif d'ajustage de la table de tri ast0 destiné à modifier sa sélectivité, . As indicated above the adjustment device of the sorting table ast0 intended to modify its selectivity,
11 peut agir sur la vitesse de oonvovege, sachant qu'une vitesse de oonvoyage plus élevée augmente la sélectivité du orlble, les fruits ayant davantage tendance â rester dans la plan de oonvoyage et à ne pas traverser le crible lorsqu'ils sont animés d'une vi e e élevée dans la sens de convoyage. Le dispositif d'ajustage paut encore agir ayr la calibre du crible. La calibre correspond i l'ouverture du crible, c'est â dire sa sélectivité. La oallbre est déterminé par la dimension des passages de fruits du crible. Dana le cas r^rtlouflar d'un cnble comprenant des rouleaux oonvoyeura-trl ura, le calibre du crible peut être ajusté an modifiant, par exemple, !%spacemertt antre las rouleaux son¥oyayr« rtauri.. It may affect the speed of feeding, as a higher speed of travel increases the selectivity of the fruit, as the fruit is more likely to remain in the plane of travel and not to pass through the screen when animated. a high vision in the conveying direction. The adjustment device can still act on the gauge of the screen. The size corresponds to the opening of the screen, ie its selectivity. The size is determined by the size of the fruit passages of the screen. In the exemplary case of a cable comprising air-rollers, the screen size can be adjusted by changing, for example, the spacing between the rolls and the roll.
H convient de préciser que la dimension des passages de fruits du crible, n'est pas écessairem nt constat ni uniforme le long de la table de tri. Le calibra s'entend ainsi somme une valeur moyenne d¾yvarlara du cribla,  It should be pointed out that the size of the fruit passages of the screen is not necessarily neither uniform nor consistent along the sorting table. The calibra is understood as an average value of yvarlara of the cribla,
La dispositif d'ajustage paut encore agir sur la pyantlté da fhA présenta sur le erlblas en modifiant un débit d'alimentation du convoyeur. Ca débit peut être modlflès par exemple an modifiant f ouverture ou la pente d'une trémie de déversement da le récolte ayr le mm dsadmiaalon du convoyeur, an modifiant la vitesse o 'é é e ent da la machine de récolte, The adjustment device can still act on the pyantlté da fhA presenta on the erlbla s by changing a feed rate of the conveyor. Ca modlflè s flow can be for example an amending f opening or the slope of a transfer hopper da the harvest the ayr mm s admiaalon the conveyor, an changing the speed o 'E E E da ent the harvesting machine,
Enfin la dispositif d'ajustage peyt agir sur une Inclinaison du convoyeur et dons do crible par rapport i iborfeonfile dans la direction de convoyage. Une faible Inclinaison dy cribla par rapport à fhon¾onta!es voire une Inclinaison négative en orientant vers le haut la zone de décharge, a tendance â réduira sa sélectivité tandis u'u e Inclinaison plus forte a tendance à augmenter la sélectivité du cribla, les forces de gravité accélérant alors la vitesse des tulle. Finally, the adjusting device can act on an inclination of the conveyor and the sieve has to be compared with the other in the conveying direction. Low Tilt dy riddled over fhon¾onta! Century even negative tilt in facing up the discharge area, a trend â reduce its selectivity while u'u e stronger inclination tends to increase selectivity riddled the gravitational forces then accelerating the speed of the tulle.
Dans une réalisation très sommaire de l'Invention la m sure effectuée par la dispositif de mesure sur le tronçon de référença peut être affichée et peut être mise à profit par un utilisateur pour actionner le dispositif d'ajustage, In a very brief embodiment of the invention the measurement made by the measuring device on the reference section can be displayed and can be put to use by a user to actuate the adjustment device,
Toutefois.- et selon un® caractéristique particulièrement avantageuse, le dispositif d'ajustage peut être asservi au dispositif de mesure, pour un ajustement automatique. Ainsi, le dispositif d'ajustege peut tre configuré pour ajuster en temps réel le réglage de la table de tri en fonction de la quantité da frute traversant le crible ayr la tronçon de référence, et garantir ainsi un réglage optimal tenant compte notamment des variations da le qualité da la récolte traitée. L'asservissement est décrit de manière plus détaillée dans la suite du texte. Le dispositif de masure de la qmrmê ou du dédît da truite traversant fa tronçon da référence du orlble peut être un dispositif da mesura d'une valeur Instantanée, ou, de préférence, on dispositif de mesura Intégrateur éfmA i une mesure sur una certaine durée da temps.. L'utilisation d'un dispositif de masure intégrateur panne! da lisser las mesures ai évita de régler la tabla da tri en tenant compte da valeurs Instantanées anormales.. However, and according to a particularly advantageous characteristic, the adjustment device can be slaved to the measuring device for automatic adjustment. Thus, the adjustment device can be configured to adjust in real time the adjustment of the sorting table as a function of the quantity da frute passing through the screen ayr the reference section, and thus ensure an optimal adjustment taking into account in particular the variations of the quality of the treated crop. The enslavement is described in more detail in the rest of the text. The device for masking the dither or dither trout passing through the reference section of the oracle can be a device of measurement of an instantaneous value, or, preferably, the measuring device can be measured for a certain period of time. time .. The use of a device integrator home failure! To smooth the measurements, I avoided adjusting the sorting table taking into account abnormal instantaneous values.
Selon una réalisation possible du dispositif da mesure, celuM peut comporter eu moins una barrière optique disposée sur n passage da fruits ménagé sous le tronçon da ré érence da crible, at un totalis teur à' wûu da la banlèrs optique. On co s dè e que la barrière optique est disposée sur on passage da fruits connecté au tronçon da référence lorsque les toits travers»! la partit du crible sonespondant au tronçon de référença sont émanés à passer devant la barrière optique avant d'éteindre la »na da ioaption des fruits triés, According to a possible embodiment of the measurement device, this device may comprise at least one optical barrier arranged on a passage of fruits formed under the section of the screen, and a totalizer at the bottom of the optical compartment. It is said that the optical barrier is arranged on a passage of fruits connected to the reference section when the roofs cross! the part of the screen corresponding to the section of reference are emanated to pass in front of the optical barrier before extinguishing the na na tion of the sorted fruits,
La barrière optique peut oomperter un ou plusieurs falsoeauK lumineux qui sont Interrompus par le passage des toits, ou da débris traversant la crible, provenant du tronçon de référence du cribla. Le nombre et le diamètre des faisceaux lumineux sont da préférence adaptés i la tailla des fruits de manière à éviter una ouverture Intempestive da la barrière dans le aas d'an passage de a t la barrlèn- optique d'objets slgnlfloatlvement plus petite que las fruits, par exemple, des pépins ou de petits débris. The optical barrier may be blown off one or more light waves that are interrupted by the passage of roofs, or debris passing through the screen, from the reference section of the screen. The number and diameter of the light beams are preferably adapted to the size of the fruit so as to avoid an untimely opening of the barrier in the passageway of the light-bar of objects which is smaller than the fruit. for example, pips or small debris.
Le totalisateur d'ouverture associé à la barrière optique peut être un compteur d'un nombre d'ouvertures par unité de temps, La totalisateur compte ainsi la nombre d'ouvertures de la barrière optique par unité de temps et délivre on signal de mature représentatif du nombre de fruits passés i travers la tronçon de référence du crible par unité de temps. The opening totalizer associated with the optical barrier can be a counter of a number of openings per unit of time. The totalizer thus counts the number of openings of the optical barrier per unit of time and delivers a representative mature signal. the number of fruits passed through the reference section of the screen per unit of time.
L'utilisation d'un compteur du nombre d'ouvertures est adapté lorsque la flux de fruits traversant le tonçon de référence du crible est relativement faible. Lorsque le flux déviant plus Important une situation peut sa produire où la faisceau lumineux de la barrière optique resta Interrompu pendant una serlalne durée da temps af que pendant cette durée, plusieurs fruits passent devant la barrière. Dans » te i©t§flsa»ur d'ouverture peut da pr^érenoe être configuré pour établir un rapport entre une durée de temps d'ouverture da la barri re optique et une durée de référ nça. Pa ex mple* le testateur d'ouverture peut être configuré pour établir un mpport ntre une durée de tem s d'ouverture de la tanière optique et une dorée de temp de fermeture de la barrière o tique»The use of a counter of the number of openings is adapted when the flow of fruit passing through the reference wheel of the screen is relatively low. When the flow deviates more important a situation can occur where the light beam of the optical barrier remained interrupted during a period of time af that during this time, several fruits pass in front of the barrier. In this example, the opening angle may be set to establish a ratio between an opening time of the optical barrier and a reference time. Pa * ex mple the opening testator may be configured to establish a mpport etween a period of tem s opening of the optical den and a golden closure temp barrier o tick "
Les temps d'ouverture, respectivement de îmtmï , de la barrière optique sont ooroprle comme dea temps tore desquels le faisceau est Interrompu, respectivement ininterrompu. La totâllssteyr if ouverte peut encore m blmr les deux modes da comptage, The opening times of the optical barrier, respectively, are as long as the toroidal time of which the beam is interrupted, respectively uninterrupted. The open window can still mblm the two counting modes,
Selon un mode de ml» m œu re plue sophistiqué, I® dispositif de meeure de la qyantlté ou du débit de fruits frevereenf le tronçon de riféranoe du crible peut encore comporter une oamére et un sptème de treltement d'Image assoolé à le caméra. Le caméra et le système de treltement d'Image peuvent être configurés pour établir un nombre et une taille des objets traversant la tronçon de référence du orlbte. Dans ee sas le treltement de limage fournit directement une estimation du débit de fruits dans le tronçon de référence du crible et permet de discriminer, al nécessai e, les fruits des débris tra ersant accidentellement le crible, According to a more sophisticated mode of operation, the device for measuring fruit quantity or fruit flow fre- quency of the riféranoe section of the siever may further comprise a camera and a trotter of Image Assooled to the camera. The camera and the image trelt system can be configured to establish a number and size of objects traversing the reference section of the orbiter. In this case, the image treltement directly provides an estimate of the fruit flow in the reference section of the screen and makes it possible to discriminate, as necessary, the fruits of the debris accidentally trailing the screen,
Selon une autre possibilité de réalisation du dispositif de mesure assoolé au tronçon de référence du crible, celui-ci peut comporter un déflecteur disposé dans une chute de trolls entre la tronçon de référence du crible et la zone de réception da fruits triés, et un totalisateur dimpaets sur la déflecteur. Le déflecteur est, par exemple, une tôle sur laquelle tombent les fruits qui traversent le tronçon de référence du oribie, et le totalisateur tflm acts peut comporter un aceéléromètre solidaire du déflecteur, L'acoélèrométre peut, dans ce cas, être calibre de préférence pour comptabiliser des impacts de fruits et non d'objets plue petits comme des pépins da fruit According to another embodiment of the measuring device assooled with the reference section of the screen, it may comprise a deflector disposed in a troll drop between the reference section of the screen and the sorted fruit receiving area, and a totalizer dimpaets on the baffle. The deflector is, for example, a plate on which the fruits that cross the reference section of the oribie fall, and the totalizer tflm acts may comprise an aceéléromètre integral with the baffle, the acoélèrètre can, in this case, be caliber preferably for count impacts of fruits and not more small objects like fruit seeds
Le comptage des Impacts tout comme le comptage de l'ouverture d'une barrière optique est oileyi adapté ay comptage d'un flux discret de traits que peur l'évaluation d'un flux continu. Il est ainsi réservé de préférence à un tronçon de référence de petite longueur. Pour y?n mesure à la Ibis d'un flux discret et continu, a dispos!!!! da mesure associé au tronçon da référença peut encore comporter un déflecteur monté pivotant dans une chute de fruits antre la tonçs da référence du cribla ai la zona da réception de fruits triés, La déflecteur pivotant est associé ê un rassort de rappel du déflecteur dans une position da repos, at un capteur da dêfteilon angulaire du déflecteur par rapport i la position de repos. Le capteur peut êtra un capteur optique ou un capteur â potentiomètre, par exemple., The counting of impacts as well as the counting of the opening of an optical barrier is oileyi adapted ay counting a discrete flow of features that scares the evaluation of a continuous flow. It is thus preferably reserved for a reference section of short length. To measure the Ibis with a discrete and continuous flow, has arranged !!!! The measure associated with the section da referença may further comprise a baffle pivotally mounted in a fall of fruits antre the tonçs da reference cribla ai zona receiving sorted fruits, The pivoting baffle is associated with a return restor of the deflector in a position da rest, has an angular deflector sensor deflector relative to the rest position. The sensor may be an optical sensor or a potentiometer sensor, for example.
Dans oa ces l'importance da la dèflaxlon angulaire du déflecteur dépend du nombre da fruits qui atteint la déflecteur par unité de temps et donna une mesura du flux da traits traveraant le tronçon da référence du cribla, Where the importance of angular deflector deflection depends on the number of fruits reaching the deflector per unit of time and gives a measure of the flow of strokes passing through the reference section of the screen,
La dispositif de mesure peut aneore comporter un réceptacle da fruits dis osé en aval du tronçon de référence du crible dans la lone de réception de fruits triés, at un totalisateur de masse de truite dans le rec-apîaole» La totalisateur de niasse peut être une jauge de contrainte mesurant la massa ou l'accroissement de la massa da fruits dans la réceptacle., La réceptacle peut comporter un système da vidage automatique da son contenu * sain de le massa des fruits triés', The measuring device may have a fruit receptacle disposed downstream of the reference section of the screen in the sorted fruit receiving lone, and a trout mass totalizer in the recess. strain gauge measuring the massa or increased massa da fruit in the container., the receptacle may include a da da-emptying system * its healthy content massaged sorted fruit '
Comme mentionné précédemment a ysta§a de la table de tri peut avoir lieu en agissant sur un ou plusieurs paramètres. L'un da cas paramètres peut être notamment la vitesse da convo ge, Un oonvoyoge lent favorise le passage des fruits i fravara les ouvertures du crible avant qu'ils r attelgnent la zone da décharge. Inversement, un oonvoyage rapide favorise Favenoée des fruits dans la plan de oonvoyaga plutôt que tour Iravemée du crible, ca qui tend ainsi à augmenter la sélectivité du cribla, As mentioned previously, the sort table can take place by acting on one or more parameters. One of the parameters may be in particular the speed of convoy, A slow oonvoyoge favors the passage of fruits i fravara the openings of the sieve before they reaelgnent the area da discharge. Conversely, a rapid harvesting favors the fruit in the oonvoyaga plan rather than the screened turn, which tends to increase the selectivity of the screen,
Ainsi lorsque- le dispositif d'ajustage agit sur la vitesse de co voya^ l peut comporter un v rlateur agissant sur un organe moteur, I! peut s'agir de f un parmi : Thus, when the adjusting device acts on the traveling speed, it can comprise a vibrator acting on a driving member. may be one of:
