DISPOSITIF D'ALIMENTATION AUTOMATIQUE
POUR MACHINE A CALIBRER LES HUITRES, AUTRES COQUILLAGES
OU OBJETS DE FORME SIMILAIRE
Cette invention est relative à un dispositif destiné à assurer une alimentation automatique en huîtres vers une calibreuse.AUTOMATIC FEEDING DEVICE
FOR CALIBRATING OYSTERS, OTHER SHELLS
OR SIMILAR OBJECTS
This invention relates to a device intended to ensure an automatic supply of oysters to a grading machine.
Cette invention permet d'éviter l'inconvénient d'alimenter manuellement une machine à calibrer pour un débit bien supérieur. This invention avoids the disadvantage of manually feeding a machine to be calibrated for a much higher flow rate.
Les huîtres en vrac sont disposées dans la trémie d'un chargeur élévateur (1), qui mut par un moteur réducteur variateur assure au mieux une arrivée en huîtres vers des rouleaux mobiles (2) qui sont chargés d'éliminer dans leur rotation les huîtres au mauvais positionnement et en excédent. La vitesse de rotation est judicieuse ainsi que leur écartement "entr'axe", la pente de ces rouleaux qui assure la mise en ligne des huîtres est variable en fonction de la forme et de la région de production des huîtres. The oysters in bulk are placed in the hopper of a lifting loader (1), which mut by a variator reduction motor ensures at best an arrival in oysters towards mobile rollers (2) which are responsible for eliminating oysters in their rotation in the wrong position and in excess. The speed of rotation is judicious as well as their spacing "center to center", the slope of these rollers which ensures the putting in line of the oysters is variable according to the shape and the region of production of the oysters.
A la sortie des rouleaux aligneurs (2), une goulotte de transfert (3) d'une forme judicieuse assure la liaison entre les rouleaux aligneurs (2) et le dispositif d'alimentation automatique (4). At the exit of the alignment rollers (2), a transfer chute (3) of a judicious shape ensures the connection between the alignment rollers (2) and the automatic feed device (4).
Cette goulotte (3) est suffisamment longue pour maintenir le transfert d'une huître à chaque rotation des cônes (4) qui sont munis d'un pas de vis non régulier mais parfaitement synchronisé entre la calibreuse pour l'équivalent de une rotation complète des deux cônes (4) pour une balancelle de pesée (6). This chute (3) is long enough to maintain the transfer of an oyster at each rotation of the cones (4) which are provided with an irregular screw pitch but perfectly synchronized between the grader for the equivalent of a complete rotation of the two cones (4) for a weighing swing (6).
Une brosse à poils souples et longs (5) est placée sur champ et en bout de la goulotte (3) au-dessus de celle-ci afin d'empêcher certaines huîtres de faire la culbute. A brush with flexible and long bristles (5) is placed on the field and at the end of the chute (3) above it in order to prevent certain oysters from tumbling.
Si tous les éléments précités sont plus ou moins nécessaires au bon fonctionnement de l'invention, la partie (4) dite alimentation automatique reste la plus visée dans son originalité et son principe de fonctionnement. If all the aforementioned elements are more or less necessary for the proper functioning of the invention, the part (4) called automatic feeding remains the most targeted in its originality and its operating principle.
L'idée consiste en deux cônes traversés par deux axes, eux-mêmes supportés par des paliers aux extrémités et entraînés dans une rotation synchronisée vis-à-vis des godets de la calibreuse à alimenter. Une légère pente, un espace judicieux entre chaque cône et une vis hélicoïdale à pas inverse obligent les huîtres mal positionnées à s'éjecter de la vis. The idea consists of two cones crossed by two axes, themselves supported by bearings at the ends and driven in a synchronized rotation with respect to the buckets of the grader to be fed. A slight slope, a judicious space between each cone and a helical screw with reverse pitch force the badly positioned oysters to eject from the screw.
Par contre, les huîtres (7) correctement positionnées sont entraînées par les filets des vis coniques avec la différence que les filets ne sont pas d'un pas régulier mais au contraire, donc plus le diamètre du cône augmente, plus le pas de vis est long ceci, à l'image inverse du cône placé à côté. Tout le système réside
1) Lorsque des huîtres arrivent en "début de cône", peu importe le moyen (quoiqu'il soit préférable qu'elles arrivent en long), deux huîtres ne peuvent rester pour une seule place donc, une des deux doit disparaître. On the other hand, the oysters (7) correctly positioned are entrained by the threads of the conical screws with the difference that the threads are not of a regular pitch but on the contrary, therefore the more the diameter of the cone increases, the more the pitch of the screw is along this, in the opposite image of the cone placed next to it. The whole system resides
1) When oysters arrive at the "beginning of the cone", whatever the means (although it is preferable that they arrive long), two oysters cannot remain for a single place therefore, one of the two must disappear.
2) la deuxième constatation fait remarquer que des huîtres arrivées en travers se mettent en long grâce au système ; ce qui est meilleur pour l'arrivée dans le godet de la calibreuse (6). 2) the second observation points out that oysters arriving crosswise get long thanks to the system; which is better for the arrival in the grader cup (6).
3) Lorsque les huîtres arrivent en début de cône, on remarquera que la vitesse de rotation de I tour et demi ou plus à la seconde (vitesse synchronisée au passage des godets de la calibreuse par une loi mathématique) est très faible que l'huître a le temps de prendre sa place et dans sa meilleure position puis, entraînée par le filet apparent "d'un diamètre judicieux" fait que l'huître avance de plu s en plus vite d'une part, grâce au filet et d'autre part, grâce à la vitesse de plus en plus rapide en déroulement du cône "qui augmente son diamètre". Phénomène intelligent qui, sans réduire le poids de l'huître lui donne une mobilité exceptionnelle comme si elle était dûe à un coussin d'air et que, si éventuellement deux huîtres étaient encore lâ pour une seule place, très souvent la vitesse de déroulement éjecterait la gênante. 3) When the oysters arrive at the start of the cone, it will be noted that the rotational speed of I turn and a half or more per second (speed synchronized with the passage of the grader's buckets by a mathematical law) is very low than the oyster has time to take its place and in its best position then, carried along by the apparent net "of a judicious diameter" causes the oyster to advance more quickly on the one hand, thanks to the net and other part, thanks to the increasingly rapid speed in unrolling of the cone "which increases its diameter". Intelligent phenomenon which, without reducing the weight of the oyster gives it exceptional mobility as if it were due to an air cushion and that, if possibly two oysters were still there for a single place, very often the speed of unwinding would eject annoying.
4) En fin de cône, les deux filets arrivant en même temps et parfaitement synchronisés à l'arrière du godet font que l'éjection de l'huître est pratiquement parfaite dans la précision. 4) At the end of the cone, the two threads arriving at the same time and perfectly synchronized behind the bucket make the ejection of the oyster practically perfect in precision.
Toutes les huîtres non alimentées correctement sont récupérées par des moyens différents et dirigées vers la trémie de l'élévateur (1) pour une prochaine réalimentation. All oysters that are not properly fed are collected by different means and sent to the elevator hopper (1) for the next refueling.
