Description
La présente invention concerne un procédé de production optimisée de rondelles de liège naturel pour la fabrication de bouchons selon le préambule de la revendication 1. Un tel procédé est connu du document
L'invention couvre aussi un dispositif associé selon le préambule de la revendication 5. Un tel dispositif est connu du document
Le liège naturel est récolté à partir du chêne liège et les récolteurs retirent des planches de lièges de dimensions variables. Il convient d'attendre près de 50 ans avant de pouvoir disposer de planches de bonne qualité, utilisables dans la bouchonnerie. On dispose donc d'une planche avec une croûte qui est la face extérieure, un ventre côté intérieur, correspondant à la face orientée vers le tronc et la mie qui est la partie noble de la planche, entre la croûte et le ventre. Les propriétés exceptionnelles du liège, notamment de la mie, permettent de l'utiliser pour de nombreuses applications dont celle concernée plus particulièrement par la présente invention à savoir le bouchage.Natural cork is harvested from cork oak and harvesters remove cork boards of varying sizes. It is necessary to wait nearly 50 years before being able to have boards of good quality, usable in the cork. We therefore have a plank with a crust which is the outer face, a belly on the inner side, corresponding to the side facing the trunk and the crumb, which is the noble part of the plank, between the crust and the belly. The exceptional properties of cork, especially of the crumb, make it possible to use it for many applications including the one more particularly concerned with the present invention namely corking.
Il est à noter que la meilleure qualité est celle qui se situe proche du ventre car elle présente moins de défauts.It should be noted that the best quality is that which is close to the belly because it has fewer defects.
Il existe des bouchons obtenus par découpe de liège en une seule passe de façon à réaliser des bouchons monolithiques. De tels bouchons sont destinés à être introduits dans le goulot des bouteilles de vins tranquilles.There are plugs obtained by cutting cork in a single pass so as to make monolithic plugs. Such caps are intended to be introduced into the neck of bottles of still wines.
Ces bouchons sont tubes à partir de bandes de liège découpées dans les planches de liège, le tubage étant réalisé à partir de la tranche de la bande, uniquement dans la mie.These plugs are tubes from cork strips cut in the cork boards, the casing being made from the edge of the strip, only in the crumb.
Il existe aussi d'autres procédés de réalisation de bouchons, notamment celui utilisé pour la production des bouchons de vin effervescents tels que le champagne, des boissons alcoolisées effervescentes comme le cidre ou encore pour des boissons gazeuses telles que des eaux gazeuses.There are also other methods of making corks, especially that used for the production of sparkling wine corks such as champagne, effervescent alcoholic beverages such as cider or for soft drinks such as sparkling waters.
En effet de tels bouchons nécessiteraient des épaisseurs de liège très importantes pour leur réalisation, ce qui est impossible dans des conditions économiques acceptables, voire pour des problèmes de ressource. Seule la mie étant utilisée, on constate des rendements de l'ordre de 13% uniquement car, en plus, la croûte qui n'est pas utilisée est de forte densité.Indeed, such caps would require cork thicknesses very important for their realization, which is impossible in acceptable economic conditions, or even for resource problems. Only the crumb being used, we see yields of the order of 13% only because, in addition, the crust that is not used is high density.
Aussi, de tels bouchons sont des bouchons dits techniques, c'est-à-dire réalisés en plusieurs parties, collées entre elles au moyen de colles alimentaires, à savoir une tête et des rondelles. Le nombre de rondelles est lié à la longueur de bouchon recherchée et à l'épaisseur des rondelles disponibles.Also, such plugs are so-called technical caps, that is to say made in several parts, glued together by means of food glues, namely a head and washers. The number of washers is related to the desired length of stopper and the thickness of the washers available.
Dans les vins pétillants, il faut en effet pouvoir résister à la pression donc le diamètre est plus important.In sparkling wines, it must indeed be able to withstand the pressure so the diameter is larger.
Le problème majeur est que la production du liège est lié à un processus de renouvellement très long, étalé sur plusieurs années si bien que la culture du liège est de plus en plus abandonnée au profit de productions agricoles plus rentables.The major problem is that the production of cork is linked to a very long renewal process, spread over several years, so that cork cultivation is increasingly abandoned in favor of more profitable agricultural production.
La production diminuant, les prix augmentent et il devient nécessaire d'exploiter la ressource au maximum des possibilités pour en faire des produits nobles comme les bouchons, les chutes et matière moins nobles permettant de répondre à des applications tolérant des lièges avec des imperfections ou des applications mettant en oeuvre des chutes.Production decreases, prices increase and it becomes necessary to exploit the resource to the fullest extent to make noble products such as corks, falls and less noble material to meet cork tolerant applications with imperfections or defects. applications implementing falls.
Or, ainsi que cela a été indiqué et qui est parfaitement compréhensible au regard du caractère naturel et brut du produit utilisé, les planches présentent des configurations géométriques très différentes et aléatoires.However, as has been indicated and which is perfectly understandable in view of the natural and raw nature of the product used, the boards have very different geometrical configurations and random.
Suivant l'orientation de l'arbre qui produit le liège par exemple, une planche peut présenter des épaisseurs très variables et des dimensions longueur / largeur également très différentes et, dans tous les cas, aucune planche n'est identique à une autre, y compris dans du liège premier choix. Le nombre de rondelles par cm2 de planche est quasiment constant et sans possibilité de l'améliorer avec le procédé actuellement mis en oeuvre.Depending on the orientation of the tree that produces the cork for example, a board can have very variable thicknesses and dimensions length / width also very different and, in any case, no board is identical to another, including included in first choice cork. The number of washers per cm 2 of board is almost constant and can not be improved with the method currently used.
Actuellement, les planches de liège sont débitées en bande d'une largeur supérieure au diamètre des rondelles à réaliser, ce qui génère une perte de 3 mm de liège environ pour chaque découpe de chaque bande. Il faut un premier opérateur pour réaliser cette étape.Currently, the cork planks are cut into strips of a width greater than the diameter of the washers to be made, which generates a loss of about 3 mm of cork for each cut of each strip. It takes a first operator to complete this step.
De façon connue, ces bandes sont "dégauchies" pour éliminer les surépaisseurs, la croûte, opération d'écroutage, et la mère afin de ne disposer que de la mie. On note qu'il faut un deuxième opérateur pour alimenter la machine.In a known manner, these strips are "stripped" to eliminate excess thickness, the crust, the operation of peeling, and the mother to have only the crumb. Note that it takes a second operator to power the machine.
Ces bandes sont alors tubées perpendiculairement à la bande, c'est-à-dire radialement par rapport à la planche initiale et donc au tronc, si l'on se réfère au liège en place.These strips are then cased perpendicular to the band, that is to say radially relative to the initial board and thus to the trunk, if one refers to the cork in place.
Le tubage est effectué de la croûte vers la mère, c'est-à-dire radialement de l'extérieur vers l'intérieur, même si la croûte et la mère ont été retirées.Casing is done from the crust to the mother, ie radially from the outside to the inside, even if the crust and the mother have been removed.
On note la nécessité de la présence d'un troisième opérateur pour cette opération.We note the need for the presence of a third operator for this operation.
Les rondelles sont ainsi fabriquées actuellement à l'aveugle, c'est-à-dire que les rondelles sont tubées quelle que soit l'épaisseur, les rondelles ainsi tubées sont traitées par la suite notamment en subissant le bouillage, la rectification et le tri pour que, au final, 30 à 35% soient rejetées et donc 30 à 35% de matière se trouvent perdus en plus des traitements subis. Il serait bien entendu préférable de procéder à une élimination préalablement à ces traitements.The washers are thus currently manufactured blind, that is to say that the washers are cased whatever the thickness, the washers thus cased are subsequently treated in particular by undergoing the boiling, grinding and sorting so that, in the end, 30 to 35% are rejected and therefore 30 to 35% of material are lost in addition to the treatments. It would of course be preferable to proceed with an elimination prior to these treatments.
Le procédé selon la présente invention vise à répondre à cette problématique d'optimisation de production de rondelles de lièges pour la fabrication de bouchons, quelles qu'en soient les applications.The method according to the present invention aims to address this problem of optimizing the production of cork washers for the manufacture of corks, whatever the applications.
Le but est d'optimiser d'une part la surface de la planche disponible, c'est-à-dire de tirer le plus grand nombre de rondelles par unité de surface et d'optimiser d'autre part l'épaisseur de ladite planche. Ceci permet de ne retenir que les rondelles ayant une valeur en rejetant le liège ayant peu de valeur.The goal is to optimize on the one hand the surface of the available board, that is to say to draw the largest number of washers per unit area and optimize the other side the thickness of said board . This allows to retain only the washers having a value by rejecting cork having little value.
Le procédé consiste dans sa généralité à découper des ébauches directement à partir d'une planche brute, perpendiculairement à sa surface, ceci en optimisant le volume découpé.The method consists in its generality to cut blanks directly from a blank board, perpendicular to its surface, this optimizing the cut volume.
De plus, comme les rondelles sont découpées une à une, on optimise chaque partie de la planche et on tire 1, 2 ou 3 rondelles en fonction de l'épaisseur disponible. Comme on ne débite par en bandes, il y a une économie de matière première.In addition, as the washers are cut one by one, one optimizes each part of the board and one draws 1, 2 or 3 washers according to the available thickness. As we do not sell in strips, there is a saving of raw material.
Le but de ce procédé est également d'accélérer les cadences de production.The purpose of this process is also to speed up production rates.
Le dispositif associé vise à répondre à la mise en oeuvre du procédé qui engendre des problèmes très importants liés à la découpe d'ébauches à travers toute l'épaisseur de la planche brute.The associated device aims to respond to the implementation of the method which generates very important problems related to cutting blanks through the entire thickness of the blank board.

Le procédé selon la présente invention consiste, comme résumé dans le schéma bloc de la
- 1ère étape Référence 12 : une
planche 10 de liège naturel brute est préparée préalablement de façon connue, notamment en lui faisant subir une opération de trempage dans de l'eau bouillante, ce qui permet de lui conférer une malléabilité adaptée, tout en assurant un traitement antiseptique. La planche comprend une croûte sur le dessus, une mère à la partie inférieure et une partie noble dite mie entre les deux. - 2ème étape Référence 14 : la planche est placée avec la mère vers le haut. On découpe des ébauches E (E1, E2...... En) de liège dans le sens perpendiculaire à la surface de ladite planche. Ainsi les ébauches sont découpées sur toute l'épaisseur disponible de la planche, y compris croûte et mère. Ces découpes sont réalisées avec les sections circulaires des ébauches juxtaposées les unes aux autres, soit en une opération, soit en plusieurs opérations successives de découpe de la même planche.
Les opérations de découpe en plusieurs opérations successives peuvent s'avérer nécessaires suivant l'épaisseur de la planche car il se pose un problème d'échauffement et de puissance nécessaire. En effet, l'épaisseur de l'outil de découpe lors de la pénétration de l'outil dans le liège provoque une compression radiale du liège ainsi que cela sera expliqué plus avant dans la description. Du fait des propriétés d'élasticité, de la forte capacité de résistance aux frottements de la matière, il se produit des échauffements importants car la cadence de coupe est importante. Dans le cas d'une découpe de la planche en plusieurs opérations, le procédé prévoit une première opération de découpe multiple d'ébauches E avec des outils de coupe suivant une première géométrie de points distants les uns des autres d'une distance supérieure au diamètre d'ébauche. Le procédé prévoit alors un déplacement en translation relative de la planche par rapport aux outils et au moins une autre opération de découpe multiple entre les découpes d'ébauches déjà réalisées, suivant une deuxième géométrie.
La première et la deuxième géométries peuvent être identiques.
Selon le procédé de l'invention, soit la planche est déplacée en translation sous les mêmes outils, soit les outils sont déplacés en translation par rapport à la planche, soit encore la planche est déplacée d'un premier jeu d'outils sous un autre jeu d'outils autant qu'il y a d'opérations de découpe multiple.
Avantageusement, le procédé selon la présente invention prévoit deux opérations de découpe multiple d'ébauches E d'une même planche. - 3ème étape Référence 16 : le procédé prévoit ensuite une résection de chaque ébauche, de préférence en lot, afin de supprimer les irrégularités de la mère de chaque ébauche. Cette étape de résection consiste à retirer sur chaque ébauche une épaisseur constante perpendiculairement à son axe de découpe c'est-à-dire que l'on retire une rondelle d'une épaisseur donnée. On plaque chaque ébauche contre une butée de référence afin de ne retirer que le minimum nécessaire de la mère de chaque ébauche.
- 5ème étape Référence 18 : au cours de cette étape, une fois l'extrémité de l'ébauche parfaitement nette et régulière, le procédé prévoit de mesurer la longueur L (L1, L2, ...Ln) de chaque ébauche E (E1, E2...... En) ainsi réséquée y compris une mesure par lot. Chaque ébauche est ensuite découpée en rondelles, de façon optimisée, pour limiter les pertes en fonction de la longueur. Cette opération d'optimisation peut être réalisée par un logiciel. La longueur de chaque ébauche est divisée par les épaisseurs de rondelles théoriques définies pour que la somme des épaisseurs théoriques de rondelles soit la plus proche de celle de la longueur totale disponible de l'ébauche.
- 6ème étape Référence 20 : les rondelles issues de chaque ébauche sont collectées et la chute, côté croûte, est éliminée.
- Reference 1 st step 12: a
board 10 of raw natural cork is previously prepared in a known manner, in particular by subjecting a dipping operation in it to boiling water, which allows to impart a suitable malleability, whilst ensuring a antiseptic treatment. The board includes a crust on the top, a mother at the bottom and a noble part called crumb between the two. - Step 2 Reference 14: the board is placed with the mother upwards. E blanks (E1, E2 ...... En) of cork are cut in the direction perpendicular to the surface of said board. Thus the blanks are cut on all the available thickness of the board, including crust and mother. These cuts are made with the circular sections of the blanks juxtaposed to each other, either in one operation, or in several successive cutting operations of the same board.
Cutting operations in several successive operations may be necessary depending on the thickness of the board because there is a problem of heating and necessary power. Indeed, the thickness of the cutting tool during the penetration of the tool in the cork causes a radial compression of the cork as will be explained further in the description. Due to the elasticity properties, the strong resistance to friction of the material, there is significant heating because the rate of cutting is important. In the case of a cutting of the board in several operations, the method provides a first multiple blank cutting operation of blanks E with cutting tools according to a first geometry of points distant from each other by a distance greater than the diameter debauchery. The method then provides a displacement in relative translation of the board relative to the tools and at least one other multiple cutting operation between blank cuts already made, according to a second geometry.
The first and second geometries can be identical.
According to the method of the invention, the board is moved in translation under the same tools, or the tools are moved in translation relative to the board, or the board is moved from one set of tools under another tool set as much as there are multiple cutting operations.
Advantageously, the method according to the present invention provides two operations of multiple cutting blanks E of the same board. - Step 3 Reference 16: The method then provides for a resection of each blank, preferably in batch to remove the irregularities of the parent of each blank. This resection step consists in removing on each blank a constant thickness perpendicular to its cutting axis, that is to say that a washer of a given thickness is removed. Each blank is plastered against a reference stop to remove only the minimum required from the mother of each blank.
- Step 5 Reference 18: During this step, once the end of the blank perfectly sharp and regular, the method provides for measuring the length L (L1, L2, ... Ln) of each blank E (E1 , E2 ...... En) as well resected including one batch measurement. Each blank is then cut into slices, in an optimized way, to limit the losses according to the length. This optimization operation can be performed by software. The length of each blank is divided by the thicknesses of theoretical washers defined so that the sum of the theoretical thicknesses of washers is the closest to that of the total available length of the blank.
- 6th
stage 20 Reference: washers from each blank are collected and fall, crust side is eliminated.
Ce procédé permet d'éliminer uniquement la mère de façon optimisée car la mère éliminée est celle qui est propre à chaque ébauche. La longueur de chaque ébauche est prise en compte pour le choix de la découpe et l'optimisation du nombre de rondelles.This method makes it possible to eliminate only the mother in an optimized way because the eliminated mother is that which is specific to each blank. The length of each blank is taken into account for the choice of cutting and the optimization of the number of washers.

Lorsque le poinçon pénètre dans le liège, l'épaisseur de chaque tube provoque des forces F de compression radiale et du fait de la vitesse de pénétration, de la très forte capacité d'attrition du liège et de la surface importante de contact, il se produit un échauffement susceptible de provoquer des dégradations du liège en le noircissant jusqu'à des dégradations des outils dont les traitements thermiques sont modifiés.When the punch penetrates into the cork, the thickness of each tube causes forces F of radial compression and because of the speed of penetration, the very high attrition capacity of the cork and the large surface of contact, it is produces a heating that can cause damage to the cork by blackening it until damage to tools whose heat treatments are modified.
Aussi, la présente invention propose un dispositif avec une variante du poste de poinçonnage pour répondre au problème qui vient d'être expliqué.Also, the present invention provides a device with a variant of the punch station to address the problem just explained.
Le dispositif selon la présente invention est maintenant décrit en regard des
Sur la
Le poste 28 de poinçonnage comprend un convoyeur 42 destiné à recevoir une planche 10 brute de liège, après prétraitement à l'eau bouillante par exemple. Cette planche 10 est posée sur un convoyeur 42 avec sa face "croûte" côté convoyeur, c'est-à-dire le côté convexe vers le convoyeur.The punching
Ce poste 28 comprend plusieurs outils 22-1 et 22-2 de coupe, c'est-à-dire des poinçons sous forme de tubes à section circulaire, munis d'un bord 24 d'attaque affiné formant un bloc poinçon 46.This
Selon un premier mode de réalisation du dispositif selon la présente invention, il est prévu un traitement de surface adapté des outils de coupe afin qu'ils résistent à la montée en température et de façon à limiter cette montée en température. Il est aussi prévu des moyens de lubrification, non représenté car à la portée de l'homme de l'art avec un lubrifiant présentant des qualités alimentaires pour le cas particulier du bouchon et plus généralement pour toutes les applications où le liège est susceptible d'entrer en contact avec un produit alimentaire.According to a first embodiment of the device according to the present invention, a suitable surface treatment of the cutting tools is provided so that they resist the rise in temperature and so as to limit this rise in temperature. It is also provided lubrication means, not shown because within the reach of those skilled in the art with a lubricant having food qualities for the particular case of the cap and more generally for all applications where the cork is likely to come in contact with a food product.
Il peut s'agir d'une dépose par vaporisation, ou par contact au défilement dudit lubrifiant sur la périphérie du tube, immédiatement avant la phase de poinçonnage.It may be a vaporization deposit, or a sliding contact of said lubricant on the periphery of the tube, immediately before the punching phase.
Le bloc poinçon 46, multi outils 22, est manoeuvré en translation perpendiculairement à la surface de la planche par tout moyen 48 de manoeuvre adapté, en l'occurrence un vérin 50 pour venir découper, grâce aux outils, des ébauches E de liège.The
Il est prévu un premier poste 52 de transfert qui comprend des moyens de manoeuvre en translation du bloc poinçon 46 multi empreintes et des ébauches qu'il contient, au moins une navette 56 de recueil des ébauches comportant un bloc 58 avec le même nombre de logements 60 que d'outils 22, suivant la même géométrie de disposition, pour recevoir les ébauches et des moyens 62 éjecteurs des ébauches de chaque outil vers le logement 60 correspondant des navettes. Avantageusement, les moyens 62 éjecteurs sont des pistons mobiles en translation, venant au droit de la partie supérieure des outils, et poussant les ébauches à travers lesdits outils lors des mouvements en translation.There is provided a
En sortie du poste 28 de poinçonnage, on dispose donc d'une navette 56 comportant des logements 60 avec une géométrie de disposition correspondant à celle des outils 22.At the outlet of the punching
Selon un second mode de réalisation, le dispositif selon la présente invention comprend un bloc poinçon 46 multi outils mais comportant un nombre réduit d'outils 22, par exemple la moitié, disposés suivant une géométrie telle que chaque outil est séparé de chacun des outils juxtaposés, par une distance égale à au moins le diamètre d'un des outils. Une disposition en quinconce de ces outils en nombre moitié est une solution.According to a second embodiment, the device according to the present invention comprises a
De ce fait, comme cela est indiqué dans le procédé de l'invention, il convient de réaliser deux coups de poinçonnage pour réaliser la totalité des ébauches E de façon optimisée, après un mouvement relatif de la planche par rapport au bloc poinçon 46.Therefore, as indicated in the method of the invention, it is necessary to perform two punching strokes to achieve all the blanks E in an optimized manner, after a relative movement of the board relative to the
Avantageusement, il est prévu des moyens de déplacement en translation relative de la planche 10 et du bloc poinçon 46.Advantageously, there are provided displacement means in relative translation of the
Selon un mode préféré de réalisation le bloc poinçon 46 est déplacé en translation suivant une direction perpendiculaire à la direction de convoyage de la planche, entre les premier et second coups de poinçonnage de sorte à pouvoir découper toutes les ébauches nécessaires en laissant le minimum de matière, comme cela sera expliqué lors de la description du fonctionnement du dispositif et de la mise en oeuvre du procédé.According to a preferred embodiment, the
On constate que les deux modes de réalisation peuvent aussi être combinés c'est-à-dire un bloc poinçon 46 avec un nombre réduit d'outils, des moyens de déplacement en translation relative du bloc poinçon et de la planche, et/ou une lubrification et/ou un traitement de surface des outils.It can be seen that the two embodiments can also be combined, that is to say a
En variante totalement équivalente, on peut prévoir un convoyeur avec des supports de planche 10 qui se meuvent en translation en lieu et place des déplacements du bloc poinçon 46 multi empreintes. Le but, comme le requiert le procédé, est de disposer d'un mouvement relatif entre la planche et le bloc poinçon 46 multi empreintes.In a totally equivalent variant, a conveyor may be provided with board supports 10 which move in translation in place of the displacements of the
Afin de maintenir la planche 10 parfaitement en place lors de l'opération de poinçonnage, il est prévu des moyens de pressage, non représentés, car à la portée de l'homme de l'art.In order to keep the
Ces moyens de pressage comportent selon un mode de réalisation préférentiel, au moins un rouleau presseur ou un train de rouleaux presseurs, solidaire du poste de poinçonnage.These pressing means comprise, according to a preferred embodiment, at least one pressure roller or a set of pressure rollers, integral with the punching station.
Ces moyens de pressage assurent le plaquage de la planche sur le convoyeur pendant les déplacements en translation de ladite planche et la maintiennent immobilisée pendant les coups de poinçonnage.These pressing means ensure the plating of the board on the conveyor during translational movements of said board and keep it immobilized during the punching strokes.
En sortie du poste 28 de poinçonnage, en suivant le sens de production des bouchons, le dispositif comporte le poste 30 de transfert sur un chariot 32 munis de logements 66, disposés avec une géométrie identique à celle des logements 60.At the outlet of the punching
Ces chariots 32 sont disposés en nombre sur un carrousel de façon à transférer lesdits chariots devant chaque poste.These
Le poste 30 de transfert a pour objet de déplacer les ébauches contenues dans les logements 60 de la navette 56 du poste 28 de poinçonnage dans les logements 66 du chariot 32 correspondant.The purpose of the
Dans le mode de réalisation préférentiel décrit, le chariot 32 est disposé à une distance D1 d'une butée 68 et les ébauches sont plaquées contre la butée par des pistons 70, par exemple, de façon à venir en référence sur cette butée.In the preferred embodiment described, the
Le chariot 32 est déplaçable en translation pour venir au droit du poste 34 de découpe de la mère, tout en maintenant les ébauches plaquées contre la butée 68.The
Le poste 34 de découpe de la mère comporte des moyens 72 de coupe avec une lame circulaire de coupe, entraînée en rotation comme une trancheuse, disposée à une distance D2 de la butée sur laquelle est référencée la navette avec D2 inférieure à D1.The cutting
Ainsi, la face avant de chaque ébauche est éliminée et toutes les ébauches sont mises au même niveau de référence. Ainsi, on ne retire que l'épaisseur de mère nécessaire pour chaque ébauche sans aucune nécessité de prévoir une marge de sécurité et donc une perte de matière première. On note que seule la face avant est traitée si bien que les différentes ébauches ont des longueurs différentes, en fonction de l'endroit de la planche dont elle est issue. On note que l'épaisseur maximale de mie est préservée suivant l'épaisseur initiale de la planche de liège. Au poste 36 de mesure de longueur, des moyens 74 de mesure de la longueur sont appairés avec chaque ébauche. De tels moyens peuvent avantageusement être des sondes à ultrasons par exemple, pressées contre les ébauches contenus dans chacun des logements du chariot.Thus, the front face of each blank is eliminated and all the blanks are set to the same reference level. Thus, only the thickness of mother required for each blank is removed without any need to provide a safety margin and therefore a loss of raw material. It is noted that only the front face is treated so that the different blanks have different lengths, depending on the location of the board from which it came. It is noted that the maximum thickness of crumb is preserved according to the initial thickness of the cork board. At the
Ainsi il est possible de mesurer la longueur L de chaque ébauche. Chaque longueur L1.......Ln de chaque ébauche ainsi que son positionnement dans le logement 66 correspondant du chariot 32 sont intégrés dans un logiciel de mise en oeuvre du procédé pour les postes suivants.Thus it is possible to measure the length L of each blank. Each length L1 ....... Ln of each blank as well as its positioning in the corresponding
Ainsi, le logiciel peut optimiser les différentes épaisseurs de rondelles réalisables en fonction de la longueur d'ébauche disponible, après retrait de la mère, sachant qu'il y aura une chute inutilisable qui correspond à la croûte avec un minimum de perte de mie associée.Thus, the software can optimize the different thicknesses of washers achievable according to the available roughing length, after removal of the mother, knowing that there will be an unusable fall that corresponds to the crust with a minimum associated loss of crumb .
Ainsi, on peut avoir trois postes successifs avec des épaisseurs de rondelles e1, e2 et e3 de 3mm, 4mm et 5mm.Thus, one can have three successive positions with thicknesses of washers e1, e2 and e3 of 3mm, 4mm and 5mm.
De façon générale, on prévoit un minimum de chute incluant la croûte, par exemple 2,5 mm de façon à permettre un calcul approprié.In general, a minimum drop including the crust, for example 2.5 mm, is provided so as to allow an appropriate calculation.
Pour une ébauche ayant une longueur initiale L1 = 16 mm, on peut découper 1 rondelle de 3mm, une rondelle de 4mm et une rondelle de 5mm, soit 12 mm.For a blank having an initial length L1 = 16 mm, it is possible to cut out a 3mm washer, a 4mm washer and a 5mm washer, ie 12mm.
On peut compter environ 0,5 mm de perte par coupe, soit 1,5 mm ce qui conduit à utiliser 13,5 mm de la longueur de l'ébauche. Il reste donc 2,5 mm, ce qui correspond au minimum de chute, incluant la croûte.It is possible to count about 0.5 mm of loss per section, ie 1.5 mm, which leads to using 13.5 mm of the length of the blank. It remains 2.5 mm, which corresponds to the minimum drop, including the crust.
Pour une ébauche ayant une longueur L2 = 13 mm, on peut découper de façon optimisée 1 rondelle de 5 mm et une rondelle de 4 mm, plus 0,5 mm par coupe soit 1mm, ce qui conduit à une utilisation de 10 mm de l'ébauche. Il reste donc 3 mm ce qui est supérieur au minimum de chute, incluant la croûte. La perte de mie est de 0,5mm, ce qui est négligeable.For a blank having a length L2 = 13 mm, one can cut in an optimized manner 1 washer of 5 mm and a washer of 4 mm, plus 0.5 mm per cut or 1 mm, which leads to a use of 10 mm of l 'draft. It remains 3 mm which is greater than the minimum drop, including the crust. The loss of crumb is 0.5mm, which is negligible.
Dans le mode de réalisation représenté, le premier poste 38-1 de découpe de rondelle est positionné en sortie du poste de mesure de longueur. Ce poste est de conception identique au poste de résection de la mère des ébauches E. Avantageusement les moyens de coupe à disque de coupe tournant sont conservés, seule l'épaisseur de coupe est modifiée.In the embodiment shown, the first washer cutting station 38-1 is positioned at the output of the length measuring station. This post is of identical design to the resection station of the mother of the drafts E. Advantageously, the rotary cutting disc cutting means are retained, only the cutting thickness is modified.
Sur chaque poste 38 de découpe de rondelle, il est prévu comme pour les autres postes, une butée et des poussoirs afin de mettre en référence l'ébauche, ou ce qu'il en reste, pour assurer une découpe à la longueur définie par la position de la lame rotative par rapport à la butée, ce qui définit les épaisseurs e1, e2 et e3.At each
Il est ainsi possible d'optimiser les épaisseurs de rondelles à découper dans une ébauche donnée, ce qui conduit à gagner en matière première utilisée grâce à une diminution des pertes, ébauche par ébauche.It is thus possible to optimize the thicknesses of washers to be cut in a given blank, which leads to a gain in raw material used thanks to a reduction in losses, roughing by roughing.
Le dispositif selon la présente invention permet la mise en oeuvre du procédé en optimisant l'utilisation de la matière première, en diminuant les pertes lors du tubage, en diminuant les pertes lors de la découpe des rondelles.The device according to the present invention allows the implementation of the method by optimizing the use of the raw material, by reducing the losses during the casing, by reducing the losses during the cutting of the washers.
Les rondelles ainsi obtenues sont triées dès la découpe puisque les rondelles de chaque poste de découpe sont recueillies dans des contenants adaptés, de façon à disposer de rondelles découpées dans la mie, d'une épaisseur donnée.The washers thus obtained are sorted as soon as they are cut, since the washers of each cutting station are collected in suitable containers, so as to have discs cut in the crumb, of a given thickness.
Ces rondelles peuvent ensuite être associées pour réaliser des bouchons de longueur adaptée, elles peuvent subir des traitements éventuels de surfaçage, etc.These washers can then be combined to make plugs of suitable length, they may undergo possible surfacing treatments, etc.
Le dispositif est particulièrement attractif en ce sens que la matière première est optimisée et la qualité des rondelles est assurée.The device is particularly attractive in that the raw material is optimized and the quality of the washers is ensured.
Dans le procédé et le dispositif, il est prévu d'éliminer la mère et de découper les rondelles pour ensuite laisser la croûte avec la chute mais il serait possible de réaliser les mêmes opérations en réséquant la croûte et en laissant la mère.In the process and the device, it is planned to eliminate the mother and cut the washers to then leave the crust with the fall but it would be possible to perform the same operations resecting the crust and leaving the mother.
