Description
DESCRIPTION
La présente invention concerne un dispositif pour casser les coques de noix afin d'en extraire ultérieurement le fruit sans que celui-ci soit brisé.DESCRIPTION
The present invention relates to a device for breaking the nut shells in order to subsequently extract the fruit without it being broken.
Bien que les techniques précédentes et le dispositif correspondant aient donné quelque satisfaction, on a constaté une mauvaise régularité de cassage des coques, beaucoup de noix non cassées, une necessité de calibrage dans certaine technique (brevet FR 2638947) ; et en règle gé nérale une vitesse assez faible. Although the previous techniques and the corresponding device have given some satisfaction, there has been a poor regularity in breaking the hulls, many unbroken nuts, a need for calibration in certain techniques (patent FR 2638947); and generally a fairly low speed.
Le but de la présente invention est de procurer à la clientèle une machine assurant un cassage régulier et correct ainsi qu'une capacité de cassage modulable selon le désir. The object of the present invention is to provide customers with a machine ensuring regular and correct breaking as well as a modular breaking capacity as desired.
Une machine selon l'invention comprend un ou plusieurs mandrins en rotation dont les mors articulés, disposés de façon conique et au nombre de quatre minimum, sont destinés à recevoir les noix ; la disposition conique assurant la prise de tous les diamètres de noix. A machine according to the invention comprises one or more rotating mandrels whose articulated jaws, arranged conically and at least four in number, are intended to receive the nuts; the conical arrangement ensuring the setting of all nut diameters.
Ces mors en acier sont caractérises par une lèvre formant saillie. These steel jaws are characterized by a protruding lip.
Cette saillie va permettre, lors du serrage ulterieur des mors, une amorce de cassage ; le serrage des mors, d'une valeur prédéterminée venant parfaire l'éclatement de la noix. Ces mors sont articulés en leur base sur un axe respectif et sont reliés entre eux dans leur partie superieure par des leviers qui assurent l'ouverture et la fermeture du mandrin. Les mors supportent en leur partie supérieure des languettes destinées à recevoir la noix avant l'entrée dans le mandrin et permettant d'orienter la noix dans le sens de la longueur, ce qui assure la qualité du cassage. Pendant la rotation du mandrin, les mors vont être ressérés par les leviers au moment de leur passage entre les butées mécaniques.This projection will allow, during the subsequent clamping of the jaws, a crack initiation; the tightening of the jaws, of a predetermined value coming to perfect the bursting of the nut. These jaws are articulated at their base on a respective axis and are connected together in their upper part by levers which ensure the opening and closing of the mandrel. The jaws support in their upper part of the tongues intended to receive the nut before entering the mandrel and making it possible to orient the nut lengthwise, which ensures the quality of the breaking. During the rotation of the mandrel, the jaws will be tightened by the levers as they pass between the mechanical stops.
Les mandrins peuvent être disposés en série sur le même axe ou en série sur des roues, ce qui procure une capacité de cassage inégalée. The mandrels can be arranged in series on the same axis or in series on wheels, which provides an unequaled breaking capacity.
L'invention sera bien comprise dans la description détaillée d'une réalisation, en liaison avec le dessin joint sur lequel
La fig. 1 représente en coupe une machine à casser les coques de noix ; deux mors ne sont pas représentés pour faciliter la compréhension du dessin.The invention will be clearly understood in the detailed description of an embodiment, in conjunction with the attached drawing on which
Fig. 1 shows in section a machine for breaking nut shells; two jaws are not shown to facilitate understanding of the drawing.
La fig. 2 est une vue de dessus d'un mandrin et des butées mécaniques, le doigt n'étant pas représenté sur cette figure. Fig. 2 is a top view of a mandrel and mechanical stops, the finger not being shown in this figure.
La fig. 3 représente en perspective un mors ainsi que sa coupe dia métrale destinée à montrer la forme de la lèvre. Fig. 3 shows in perspective a jaw as well as its metric cross section intended to show the shape of the lip.
Dans la réalisation représentée selon l'invention, une machine à casser les coques de noix comprend une trémie d'alimentation 1 pourvue de fentes qui permettent le passage d'un doigt de métal 2 de forme ovale. Ce doigt solidaire du mandrin, assure pendant son passage dans la trémie, la prise d'une seule noix. Le mandrin est formé de deux tubes 3 et 4 reliés entre eux par soudage sur un autre tube 5 qui est monté sur l'arbre de rotation. Ce mandrin supportant le doigt 2, les mors 6, les leviers 7, est immobilisé sur l'arbre tournant par une clavette. In the embodiment shown according to the invention, a machine for breaking the nut shells comprises a feed hopper 1 provided with slots which allow the passage of a metal finger 2 of oval shape. This finger secured to the mandrel, ensures during its passage in the hopper, the taking of a single nut. The mandrel is formed of two tubes 3 and 4 connected together by welding on another tube 5 which is mounted on the rotation shaft. This mandrel supporting the finger 2, the jaws 6, the levers 7, is immobilized on the rotating shaft by a key.
Pendant la rotation du mandrin, qui est assurée par un moteurréducteur en bout d'arbre, le doigt 2 vient déposer la noix entre les languettes 8 supportées par les mors fermés sous l'influence des leviers 7 et des butées mécaniques 9, le mandrin se trouve à la verticale comme le montre la fig. 1. Les leviers vont ouvrir les mors sous l'action d'un ressort 10, les languettes vont échapper la noix qui va se mettre en contact avec les mors 6. Ces mors sont disposés en forme de cône afin d'accueillir tous les diamètres de noix. La rotation du mandrin se poursuivant, les leviers 7 vont être soumis à l'action des butées mécaniques 11 par l'intermédiaire des roulettes anti-usure 12. Cette action a pour effet de resserrer les mors qui ont la particularité de posséder une petite lèvre coupante comme le montre la figure 3. Cette lèvre va fendre la coque de la noix avant d'être écrasée par les mors selon une course déterminée par les butées mécaniques 11 ; course qui évite l'écrasement du fruit. Après le cassage, le mandrin va s'ouvrir laissant échapper la noix. During the rotation of the mandrel, which is ensured by a geared motor at the end of the shaft, the finger 2 comes to deposit the nut between the tongues 8 supported by the closed jaws under the influence of the levers 7 and of the mechanical stops 9, the mandrel located vertically as shown in fig. 1. The levers will open the jaws under the action of a spring 10, the tongues will escape the nut which will come into contact with the jaws 6. These jaws are arranged in a cone shape to accommodate all the diameters nuts. The rotation of the mandrel continues, the levers 7 will be subjected to the action of the mechanical stops 11 by means of the anti-wear rollers 12. This action has the effect of tightening the jaws which have the distinction of having a small lip cutting as shown in Figure 3. This lip will split the shell of the nut before being crushed by the jaws according to a stroke determined by the mechanical stops 11; race which avoids crushing the fruit. After breaking, the mandrel will open allowing the nut to escape.
En pratique, un atelier de cassage sera équipé d'une ou plusieurs machines comportant un grand nombre de mandrins décalés angulairement pour réduire le couple et le bruit. In practice, a breaking workshop will be equipped with one or more machines comprising a large number of mandrels offset angularly to reduce the torque and the noise.
La machine selon l'invention est particulièrement destinée à briser les coques de noix de noyer. The machine according to the invention is particularly intended for breaking the walnut hulls.
