Abstract

The invention relates to a complementary use of the device described in Patent no. 86 03570. The ratio of the diameter of the cap to the diameter of the stem is used to separate the mushrooms into those with bulbous stems and those with cylindrical stems. Non-mechanisable mushrooms can thus be eliminated before they pass into the trimming machines.

Description

le brevet N 86 03570 intitulé "dispositif pour trier lea champignons selon la longueur dea pieds" repose sur la nesure et le calcul du rapport des deux cotes maximums situées dans deux plana perpendiculaires de chaque champignon. le présent additif décrit une application complémentaire de ce dispositif. Patent N 86 03570 entitled "device for sorting fungi according to the length of feet" is based on the measurement and calculation of the ratio of the two maximum dimensions located in two perpendicular planas of each fungus. the present additive describes a complementary application of this device.

L'hétérogénéité dea longueurs n'est pas le aeul problène rencontré dans le
parage mécanique.La conformation des pieds joue aussi un rôle important.L'idéal est
représenté par la figure 1,planche 1/1,c'est à dire un champignon avec un pied
cylindrique;mais on rencontre aussi d'autres formes:
pied bulbeux comme sur la figure 2
doublet comme sur la figure 3; nous l'assimilerons à un pied bulbeux et il sera traité comme tel.The heterogeneity of lengths is not the only problem encountered in the
The conformation of the feet also plays an important role. The ideal is
represented by FIG. 1, plate 1/1, that is to say a mushroom with a foot
cylindrical, but we also meet other forms:
bulbous foot as in Figure 2
doublet as in Figure 3; we will assimilate it to a bulbous foot and it will be treated as such.

Dans le cas d'un pied bulbeux, la machine à parer ne peut "reconnaitre" le pied du chapeau. Le problème devient d'autant plus aigu lorsque les 2 diamètres pied et chapeau se rapprochent. De tels champignons aeront recyclés dans les machines jusqu'à leur casse ou leur éjection vers le parage manuel. Leur séparation dès le départ sera sans conteste une grande amélioration dans le fonctionnement des machines,sans compter le gain de temps ou de qualité. In the case of a bulbous foot, the machine can not "recognize" the foot of the hat. The problem becomes even more acute when the 2 diameters foot and hat are getting closer. Such fungi will be recycled in the machines until they are broken or ejected to manual trimming. Their separation from the start will undoubtedly be a great improvement in the operation of machines, not to mention the time or quality saving.

le principe réside dans le calcul du rapport des deux plus grands diamètres
du chapeau (a) et du pied (c). Plus ce rapport se rapproche de un,noina les
champignons seront mécanisables. n pourra prendre comme valeur de référence:
0,9 < a/c < 1,1 = pied bulbeux,le champignon sera orienté vers
le parage manuel a a
> 1,1 ou < 0,9 = champignon mécanisable.the principle lies in the calculation of the ratio of the two largest diameters
hat (a) and foot (c). The closer this report is to one, the more
mushrooms will be mechanizable. n can take as reference value:
0.9 <a / c <1.1 = bulbous foot, the fungus will be oriented towards
manual trimming aa
> 1.1 or <0.9 = mechanizable mushroom.

c c
le calcul de cerapport ne sera fait que sur les champignons répondant au
critère "pied noyen" ou "pied long" ( voir brevet N 86 03570 ).cc
the calculation of the report will be done only on the mushrooms answering the
criterion "pied noyen" or "long foot" (see patent N 86 03570).

Le dispositif utilisé sera le nEne que celui décrit dans le brevet no 86 03570,
Mais dans cette nouvelle utilisation, l'orientation des champignons est indispen- -sable. The device used will be the same as that described in patent No. 86 03570,
But in this new use, the orientation of the mushrooms is essential.

les mesures peuvent être faites simultanément sur plusieurs lignes à
l'aide d'une caméra b capteur matriciel,voir figure 4.Les champignons porront être
orientés perpendiculairement ou parrallèlement au défilement du tapis.measurements can be made simultaneously on several lines to
Using a matrix sensor camera, see Figure 4. Fungi may be
oriented perpendicularly or parallel to the scrolling of the carpet.

les mesures pourront aussi être effectuées successivement;les champignons
sont orientés parallèlement au défilement;voir figure 5. On pourra utiliser dans
ce cas une caméra à capteur linéaire.Une série de mesures sera faite au cours de
l'avancement du champignon devant l'objectif. measurements can also be made successively;
parallel to the scroll, see Figure 5. It will be possible to use in
this case a linear sensor camera.A series of measurements will be made during
the advancement of the mushroom in front of the objective.

@n observera ainsi le passage du chapeau donnant un premier groupe de mesures avec une augmentation des cotes, puis un rétrécissement correspondant au début du -' pied. Dans le cas d'un pied bulbeux,les mensurations réaugmenteront pour donner un deuxième groupe de mesures. Dans chacun de ces groupes,seules les cotes les plus a importantes,correspondant à a et à c,seront retenues pour calculer le rapport .  Thus, the passage of the hat will be observed, giving a first group of measurements with an increase in the dimensions, then a narrowing corresponding to the beginning of the foot. In the case of a bulbous foot, the measurements will increase to give a second group of measurements. In each of these groups, only the highest scores, corresponding to a and c, will be used to calculate the ratio.

c
Le champignon peut se présenter à l'envers,celà n'a aucune importance puisqu'on peut intervertir les cotes a et c sans que celà intervienne sur le tri. c
The mushroom can be upside down, it does not matter since we can invert the dimensions a and c without it intervenes on sorting.
