Abstract

The invention relates to a device for separating mushrooms by classifying them into a number of categories: ''short-stemmed'', ''medium-stemmed'', and ''long-stemmed''. It consists of a conveyor belt and a motion camera enabling the total length 3 and diameter 2 of each mushroom to be measured. Sorting occurs afterwards on the basis of the ratio of 3:2. The invention is chiefly intended for sorting mushrooms before they are trimmed mechanically.

Description

La présente invention concerne un dispositif pour trier les champignons en fonction de la longueur des pieds. The present invention relates to a device for sorting mushrooms according to the length of the feet.

Le frein au parage mécanique des champignons réside dans l'hétéro -généité de la matière première. The obstacle to the mechanical trimming of mushrooms lies in the heterogeneity of the raw material.

Ce mélange initial entraîne:
- un recyclage important dans les machines à parer d'où des pertes de qualité,de produit1 etc.. This initial mixture results in:
- significant recycling in trimming machines, resulting in loss of quality, product1 etc.

- un règlage difficile des scies : perte de rendement technique. - difficult adjustment of saws: loss of technical efficiency.

- une reprise manuelle post machine des mal coupé s.  - manual post-machine recovery of poorly cut s.

- un renvoi de 25 à 30 % des champignons vers le parage manuel qui représente 70 % du temps de travail. - a return of 25 to 30% of the mushrooms to manual trimming which represents 70% of the working time.

Tous ces inconvénients résultent du fait qu'on n'a jamais su séparer les champignons selon la longueur des pieds.En effet tous les systèmes testés se sont heurtés à la difficulté de mesurer en continu la longueur (1) figure t.  All these drawbacks result from the fact that we have never been able to separate the mushrooms according to the length of the stems. In fact, all the systems tested have encountered the difficulty of continuously measuring the length (1) figure t.

Le but de la présente invention est de séparer puis de diriger en fonction de leur catégorie les champignons ;ee
- pied court vers le parage manuel ou des machines à parer spécialisées.The purpose of the present invention is to separate and then manage according to their category the mushrooms;
- short foot towards manual trimming or specialized trimming machines.

- pied moyen vers les machines à parer classiques dont les performances seront nettement améliorées ou vers des machines à 100% de prise1 sans recyclage,sans eau et permettant un imprégnation ultérieure optimum. - medium foot towards conventional trimming machines whose performance will be significantly improved or towards 100% setting machines1 without recycling, without water and allowing optimum subsequent impregnation.

- pied long vers les mêmes types de machines que ci dessus mais réglées différemment. - long foot towards the same types of machines as above but adjusted differently.

Il est évident qu'on pourra faire autant de catégories que l'on voudra;pour simplifier,nous n'avons retenu que les trois ci-dessus. It is obvious that we can make as many categories as we want; for simplicity, we have retained only the three above.

Le principe de la présente invention réside dans la corrélation qui existe au sein de chaque catégorie entre la longueur (1) et le diamètre (2). On peut retenir pour un "pied moyen": (1) = (2). Cette corrélation existe aussi entre la longueur totale (3) et le diamètre (2):
(3) = (2) x 1,5 pour un pied "moyen". The principle of the present invention lies in the correlation which exists within each category between the length (1) and the diameter (2). We can retain for an "average foot": (1) = (2). This correlation also exists between the total length (3) and the diameter (2):
(3) = (2) x 1.5 for a "medium" foot.

Le rapport R = (3)/(2) servira de référence dans la présente invention. The ratio R = (3) / (2) will serve as a reference in the present invention.

I < R < 1,3 : "pied court"
1,3 < R < 1,6 : pied moyen"
R > i,6 : "pied long"
Ces valeurs ne sont données qu'à titre indicati-f et pourront être modifiées selon les lots de champignons.I <R <1.3: "short foot"
1.3 <R <1.6: medium foot "
R> i, 6: "long foot"
These values are given for information only and may be modified depending on the batch of mushrooms.

Le dispositif selon la présente invention comprend :
- une bande transporteuse (4) figure 2 de couleur unifor^- -me permettant une alimentation régulière et telle que les champignons se présentent isolément devant la caméra (5).The device according to the present invention comprises:
- a conveyor belt (4) figure 2 of uniform color - - me allowing a regular feeding and such that the mushrooms stand alone in front of the camera (5).

- une ou plusieurs caméras(5) à traitement d'image (G) relié à un intégrateur calculateur qui mesurent les deux plus grandes cotes situées dans deux plans perpendiculaires de chaque champignon. Le rapport de ces deux mensurations est assimilé au rapport R, y compris dans le cas des chapeaux isolés ou de pieds presquinexistants.  - one or more cameras (5) with image processing (G) connected to a calculator integrator which measure the two largest dimensions located in two perpendicular planes of each mushroom. The ratio of these two measurements is assimilated to the R ratio, including in the case of isolated hats or pre-existing feet.

- un appareil de triage (7) qui séparera les champignons en fonction des signaux émis selon la valeur du rapport R. Cet appareil pourra entre avantageusement constitué d'un ensemble électro pneumatique. - A sorting device (7) which will separate the mushrooms according to the signals transmitted according to the value of the ratio R. This device may advantageously consist of an electro-pneumatic assembly.

les champignons seront éjectés par Jets d'air. Naturellement,d'autres systèmes pourront être utilisés : ventouses,aspiration,éjectien mécanique,jets dteau. Pour simplifier,seules deux catégories sur trois seront éjectées,la troisième,la plus importante en nombre,alimentera directement un tapis ou une goulotte de réception (8). Ce triage pourra être plus complet en séparant les champignons en fonction de leur diamètre (2) au sein de chaque catégorie.the mushrooms will be ejected by air jets. Naturally, other systems could be used: suction cups, suction, mechanical ejector, water jets. To simplify, only two categories out of three will be ejected, the third, the largest in number, will directly feed a conveyor belt or chute (8). This sorting can be more complete by separating the mushrooms according to their diameter (2) within each category.

Le dispositif selon la présente invention pourra également se situer après un calibreur classique,les champignons étant déjà séparés en fonction du diamètre du chapeau (2). Seule la longueur totale (3) sera mesurée par la caméra ou tout autre système optique puisque la valeur (2) sera connue et constante à chaque sortie du calibreur. Le principe reste le mêmeXbasé sur le rapport (3)/(2),mais le dispositif sera plus lourd et moins performant car le calibrage mécanique est peu fiable.  The device according to the present invention may also be located after a conventional sizer, the mushrooms being already separated according to the diameter of the cap (2). Only the total length (3) will be measured by the camera or any other optical system since the value (2) will be known and constant at each output from the calibrator. The principle remains the same X based on the ratio (3) / (2), but the device will be heavier and less efficient because the mechanical calibration is unreliable.

La bande transporteuse (4) pourra présenter les champignons dans tous ressens devant la caméra comme dans la figure 2;. Elle pourra également,afin de faciliter la mesure,orienter les champignons par un ensemble de courroies comme sur la figure 3 ou de rouleaux comme sur la figure 4. The conveyor belt (4) can present the mushrooms in any way in front of the camera as in Figure 2 ;. It can also, in order to facilitate the measurement, orient the mushrooms by a set of belts as in Figure 3 or rollers as in Figure 4.

Le passage devant les caméras pourra également servir à détermi -ner la qualité des champignons par la couleur
blanc beige uniforme = premier choix
taches marrons à grises = deuxième choix.The passage in front of the cameras could also be used to determine the quality of the mushrooms by color
uniform beige white = first choice
brown to gray stains = second choice.

Ce tri selon la qualité vient se superposer au précédent et n'est que l'aboutissement de la recherche de l'utilisation optimum des caméra.  This sorting according to quality is superimposed on the previous one and is only the culmination of the search for the optimum use of the cameras.

Le dispositif selon la présente invention pourra également etre utilisé pour trier dans les refus de machine,les champignons entiers des cassés (pieds et morceaux séparés).  The device according to the present invention can also be used to sort in machine rejects, whole broken mushrooms (feet and separate pieces).
