Description

La présente invention concerne un procédé de découpage d'une bande pour la réalisation de flans pour jupes de coiffes de bouteilles. Elle a des applications dans le domaine de l'embouteillage, notamment des boissons de type Champagne dont le dispositif de fermeture du goulot est recouvert d'une coiffe.The present invention relates to a cutting method of a strip for producing blanks for skirts of bottle caps. It has applications in the field of bottling, including champagne drinks whose neck closure device is covered with a cap.

Les coiffes recouvrant les dispositifs de fermeture de bouteilles notamment de Champagne sont réalisées dans des matériaux relativement couteux afin de donner un aspect luxueux aux dites bouteilles. On met généralement en oeuvre pour ces coiffes des matériaux métallisés qui comportent en outre des dispositifs d'aide à leur ouverture/déchirure ainsi que des indications diverses. Outre leur coût intrinsèque, ces coiffes doivent être réalisées et disposées sur les bouteilles de manière relativement précise afin que les dispositifs et indications puissent assurer leurs fonctions.The caps covering the closure devices of bottles, especially Champagne, are made of relatively expensive materials in order to give a luxurious appearance to said bottles. Metallic materials are generally used for these caps, which furthermore comprise devices for assisting their opening / tearing, as well as various indications. In addition to their intrinsic cost, these caps must be made and arranged on the bottles in a relatively precise manner so that the devices and indications can perform their functions.

Ces coiffes sont généralement réalisées par enroulement sur elle même autour d'un mandrin conique d'une forme appelée flan afin de former une jupe dont l'extrémité supérieure, celle de diamètre le plus réduit des deux extrémités opposées de la jupe, est ensuite fermée, soit par repliement de ladite extrémité, soit par fixation d'un chapeau, ou rondelle de tête, rapporté.These caps are generally made by winding on itself around a conical mandrel of a shape called blank to form a skirt whose upper end, the one of smaller diameter of the two opposite ends of the skirt, is then closed either by folding of said end, or by fixing a cap, or head washer, reported.

Ces opérations se déroulent dans un contexte industriel où les cadences et la qualité du résultat doivent être élevées. On met donc en général en oeuvre des procédés en continu à partir d'une feuille de matériau sous forme d'une bande que l'on découpe après les éventuelles réalisations antérieures du type impression de motifs, réalisation/installation d'accessoires (lignes de fragilisation, tire-fil...).These operations take place in an industrial context where the rates and the quality of the result must be high. Continuous processes are therefore generally carried out from a sheet of material in the form of a strip which is cut after any previous embodiments of the type of pattern printing, production / installation of accessories (lines of embrittlement, pull-wire ...).

Or le flanc résultant du découpage et destiné à former la jupe de la coiffe présente une forme contournée dont les bords ne peuvent pas tous s'ajuster à la forme de la bande et aux autres flans à découper le long de la bande. Il en résulte qu'une partie significative du matériau de la bande est éliminé pour l'obtention des flans, ce qui augmente les coûts de fabrication.Or the flank resulting from the cutting and intended to form the skirt of the cap has a contoured shape whose edges can not all adjust to the shape of the band and other blanks to be cut along the band. As a result, a significant portion of the web material is eliminated to obtain the blanks, which increases the manufacturing costs.

En effet, le flan non enroulé présente une forme générale triangulaire tronquée à son sommet et certains de ses quatre bords sont généralement incurvés. Il en résulte que le découpage d'un flan dans une bande de matériau entraine une perte de matière d'environ 16% de la surface, voire plus.Indeed, the uncoiled blank has a truncated triangular general shape at its top and some of its four edges are generally curved. As a result, the cutting of a blank in a strip of material causes a loss of material of about 16% of the surface, or more.

La présente invention a pour but d'optimiser la réalisation des flans en réduisant les pertes de matière. A cette fin, les flans sont disposés par paires et tête-bêche sur la largeur de la bande de matériau que l'on découpe pour former les flans. De plus, dans une modalité de réalisation, ce découpage de la bande se fait dans un premier temps entre les flans de la paire afin de former deux alignements ou sous-bandes de flans alignés et dans le même sens selon la longueur de la sous-bande dont chacune servira ultérieurement à la réalisation des flans individuels. Grace à l'invention, les gains en matière (surface) sont d'au moins 10% par rapports aux procédés traditionnels sans compter l'augmentation de cadence de production qui est obtenue. Parmi ces procédés traditionnels, on peut mentionner ceux décrits dans DE 14 61 955 A1 et US 2 562 423 A et FR 2 825 687 A1 .The present invention aims to optimize the realization of blanks reducing material losses. To this end, the blanks are arranged in pairs and head-to-tail over the width of the strip of material that is cut to form the blanks. In addition, in one embodiment, this cutting of the strip is done firstly between the blanks of the pair so as to form two alignments or subbands of aligned blanks and in the same direction according to the length of the sub-band. band each of which will subsequently be used to produce the individual blanks. Thanks to the invention, the gains in material (area) are at least 10% compared to traditional processes without counting the increase in production rate that is obtained. Among these methods traditional, we can mention those described in DE 14 61 955 A1 and US 2,562,423 A and FR 2 825 687 A1 .

Ainsi, l'invention concerne un procédé de découpage d'une feuille en bande de matériau simple ou complexé pour la réalisation de flans destinés à former, après sa mise en forme, chacun une jupe de coiffe de bouteille, caractérisé en ce que les flans sont découpés à partir d'un agencement des flans par paire(s), les deux flans de la paire étant tête-bêche suivant la largeur de la feuille en bande et les flans étant alignés à la file suivant la longueur de la feuille en bande, selon la revendication 1.Thus, the invention relates to a method of cutting a strip sheet of simple material or complexed for producing blanks intended to form, after shaping, each a bottle cap skirt, characterized in that the blanks are cut from an arrangement of the blanks in pairs (s), the two blanks of the pair being upside-down according to the width of the web sheet and the blanks being aligned in line along the length of the web sheet according to claim 1.

En particulier, cette machine de réalisation de flans ou de sous-bandes d'alignements de flans à partir d'une feuille en bande de materiau simple ou complexé, comporte des moyens spécifiquement destinés à produire au moins des sous-bandes d'alignements de flans par le procédé de l'invention et dans lequel les flans sont découpés à partir d'un agencement des flans par paire(s), les deux flans de la paire étant tête-bêche suivant la largeur de la feuille en bande et les flans étant alignés à la file suivant la longueur de la feuille en bande.In particular, this machine for producing blanks or subbands for aligning blanks from a web sheet of simple or complexed material, comprises means specifically intended to produce at least sub-bands of alignments of blanks by the method of the invention and wherein the blanks are cut from a pairwise arrangement of the blanks, the two blanks of the pair being upside-down depending on the width of the web sheet and the blanks being aligned in line along the length of the strip sheet.

L'invention permet d'obtenir des flans directement obtenus par le procédé de l'invention, soit sous forme d'un alignement de flans dans une sous-bande, soit en tant que flans individuels.The invention makes it possible to obtain blanks directly obtained by the method of the invention, either in the form of an alignment of blanks in a sub-band, or as individual blanks.

La présente invention, sans qu'elle en soit pour autant limitée, va maintenant être exemplifiée avec la description qui suit de modes de réalisation et de mise en oeuvre en relation avec :

  • la Figure 1 qui représente une vue de face d'une bande d'un matériau sur laquelle on a représenté la forme des flans destinés à réaliser des jupes de coiffe, une seule paire de flan étant prévue en largeur,
  • la Figure 2 qui représente une vue de face visualisant la forme du trait de découpe longitudinal de la bande de la Figure 1,
  • la Figure 3 qui schématise les traits de découpage transversaux séparant les flans les uns des autres,
  • la Figure 4 donne un détail du trait de découpe longitudinal centré sur le petit coté de la forme triangulaire périodique dudit trait de découpe,
  • la Figure 5 qui représente la bande de matériau avec des motifs et repères imprimés/réalisés à sa surface,

  • la Figure 7 qui représente une vue de face d'une bande d'un matériau sur laquelle on a représenté la forme des flans destinés à réaliser des jupes de coiffes, deux paires de flans étant prévues en largeur.
The present invention, without it being so limited, will now be exemplified with the following description of embodiments and implementation in relation to:
  • the Figure 1 which represents a front view of a strip of a material on which the shape of the blanks for making cap skirts has been represented, a single pair of blank being provided in width,
  • the Figure 2 which represents a front view visualizing the shape of the longitudinal cutting line of the band of the Figure 1 ,
  • the Figure 3 which schematizes the transverse cutting lines separating the blanks from each other,
  • the Figure 4 gives a detail of the longitudinal cutting line centered on the small side of the periodic triangular shape of said cutting line,
  • the Figure 5 which represents the strip of material with patterns and marks printed / made on its surface,
  • the Figure 6 which schematizes a machine for making caps from individual blanks, and
  • the Figure 7 which represents a front view of a strip of a material on which is represented the shape of the blanks intended to make skirts of caps, two pairs of blanks being provided in width.

Dans cette description, on a dénommé les bords des flans afin de faciliter la compréhension de l'invention. Ainsi, le bord supérieur du flan correspond au bord qui sera au sommet étroit de la jupe conique une fois le flan enroulé. Le bord inférieur du flan correspond au bord qui sera à la base large de la jupe conique une fois le flan enroulé. Les bords supérieur et inférieur sont incurvés, concave pour le supérieur et convexe pour l'inférieur. Cette dénomination est purement explicative et ne saurait limiter l'invention de quelque manière que ce soit.In this description, the edges of the blanks have been called in order to facilitate the understanding of the invention. Thus, the upper edge of the blank corresponds to the edge which will be at the narrow top of the conical skirt once the blank wound. The lower edge of the blank corresponds to the edge which will be at the broad base of the conical skirt once the blank rolled. The upper and lower edges are curved, concave for the upper and convex for the inferior. This denomination is purely explanatory and can not limit the invention in any way whatsoever.

Le premier bord latéral et le second bord latéral du flan sont les deux bords opposés qui viendront au contact l'un de l'autre lors de l'enroulement du flan sur lui même pour former la jupe conique. Les bords latéraux sont des bords droits. Toujours afin de faciliter la compréhension, on dénomme premier et second bords latéraux des bords qui ont toujours la même position par rapport aux bords supérieur et inférieur et sur une même face de la bande où sont formés les flans. Ainsi, dans ces explications, ce sont deux premiers bords latéraux de deux flans d'une paire tête-bêche sur la largeur de la bande qui sont communs/au contact l'un de l'autre. Les deux seconds bords latéraux de cette même paire sont eux aux extrémités opposées de la largeur de la bande et sont parallèles entre eux et aux deux bordures latérales de la bande, qu'ils se confondent ou pas avec ces bordures.The first side edge and the second side edge of the blank are the two opposite edges which will come into contact with each other during the winding of the blank on itself to form the conical skirt. The side edges are straight edges. Still in order to facilitate understanding, the first and second lateral edges are called edges which always have the same position relative to the upper and lower edges and on the same face of the strip where the blanks are formed. Thus, in these explanations, there are two first side edges of two blanks of a head-to-tail pair across the width of the band which are common / in contact with each other. The two second side edges of this same pair are at opposite ends of the width of the strip and are parallel to each other and to the two lateral edges of the strip, whether or not they coincide with these borders.

La bande qui est découpée pour former des flans comporte typiquement des motifs imprimés ainsi qu'éventuellement des motifs en relief et/ou des réalisations fonctionnelles comme des lignes de déchirure, des accessoires d'aide à la déchirure etc. Il est donc nécessaire que le découpage s'effectue dans des conditions précises à la fois quand au format des flans que la position des lignes de découpage sur la bande.The web that is cut to form blanks typically has printed patterns as well as possibly raised patterns and / or functional embodiments such as tear lines, tear-off aids, and the like. It is therefore necessary that the cutting is carried out under precise conditions both when the format of the blanks that the position of the cutting lines on the tape.

Ainsi, sur la Figure 1, la bande 1 de matériau qui peut être simple, par exemple feuille de métal, ou complexe, par exemple feuille de stratifié plastique-métal-plastique, et qui peut être stockée enroulée sur elle même, a été déroulée sur une certaine longueur et on y a représenté les formes des flans 5a-6a, 5b-6b, 5c-6c, qui y seront réalisés. La bande comporte deux bordures latérales 2, 3 droites et parallèles entre elles suivant la largeur de la bande 1. Dans cet exemple une seule paire 5a-6a ou 5b-6b ou 5c-6c de flans est prévue sur la largeur de la bande, dans d'autres modalités deux ou plus paires de flans peuvent être prévues. Dans chaque paire, les flans sont tête-bêche, donc inversés. Par contre, le long de la longueur de la bande, les flans de chaque paire sont dans le même sens. Il en résulte que sur la Figure 1, on a un premier alignement 5a-5b-5c des flans sur un premier coté latéral de la bande sur sa longueur (le long de la bordure 3) et un second alignement 6a-6b-6c, inverse du précédent, sur l'autre coté latéral de la bande sur sa longueur (le long de la bordure 2). Ainsi, lorsque l'on sépare les deux flans de chaque paire par une découpe médiane le long de la bande, on obtient deux sous-bandes de flans alignés et de même sens sur ladite sous-bande.So, on the Figure 1 , the strip 1 of material which can be simple, for example sheet metal, or complex, for example plastic-metal-plastic laminate sheet, and which can be stored rolled up on itself, has been unwound over a certain length and There is shown the shapes of the blanks 5a-6a, 5b-6b, 5c-6c, which will be made there. The strip has two lateral edges 2, 3 straight and parallel to each other along the width of the strip 1. In this example a single pair 5a-6a or 5b-6b or 5c-6c blanks is provided over the width of the strip, in other modalities two or more pairs of blanks can be provided. In each pair, the blanks are upside down, so inverted. On the other hand, along the length of the strip, the blanks of each pair are in the same direction. It follows that on the Figure 1 we have a first alignment 5a-5b-5c blanks on a first lateral side of the strip along its length (along the edge 3) and a second alignment 6a-6b-6c, inverse of the previous, on the other side side of the strip along its length (along the border 2). Thus, when the two blanks of each pair are separated by a median cut along the strip, two aligned blank subbands with the same direction are obtained on said sub-band.

Chaque flan présente une forme globalement trapézoïdale ou triangulaire tronquée comportant quatre bords sensiblement opposés deux à deux avec deux bords droits opposés correspondant à un premier bord latéral 9 de la jupe et un second bord latéral 10 de la jupe, et deux bords incurvés opposés dont l'un, le bord supérieur 8 du flan, est de largeur plus petite que l'autre, le bord inférieur 7 du flan, ledit flan étant destiné à être replié sur lui-même avec accolement et recouvrement partiel des deux bords droits latéraux pour former la jupe.Each blank has a generally trapezoidal or truncated triangular shape having four substantially opposite edges in pairs with two opposite straight edges corresponding to a first side edge 9 of the skirt and a second side edge 10 of the skirt, and two opposite curved edges of which one, the upper edge 8 of the blank, is of smaller width than the other, the lower edge 7 of the blank, said blank being intended to be folded on itself with joining and partial overlapping of the two side edges to form the skirt.

Dans chaque paire de flan, par exemple 5a-6a, les deux flans 5a, 6a sont inversés, tête-bêche, et leurs premiers bords latéraux 9 droits sont au contact l'un de l'autre et, par contre, leurs seconds bords latéraux sont opposés et forment, directement ou non, les deux bordures 2, 3 de la bande. Sur la Figure 1, une étroite ligne 4 de matériau sépare la bordure du second bord latéral du flan, cette étroite ligne 4 pouvant comporter des repères étant supprimée pour réalisation de la jupe.In each pair of blanks, for example 5a-6a, the two blanks 5a, 6a are inverted, head-to-tail, and their first right side edges 9 are in contact with each other and, on the other hand, their second edges side are opposed and form, directly or not, the two edges 2, 3 of the strip. On the Figure 1 a narrow line 4 of material separates the edge of the second lateral edge of the blank, this narrow line 4 may comprise pins being removed for producing the skirt.

La Figure 2 permet de visualiser le trait de découpage longitudinal 13 de la bande qui sépare en deux chacune des paires de la bande pour former deux sous-bandes de flans alignés dans le même sens dans chaque sous-bande. Le trait de découpage longitudinal a une forme en dent de scie / triangulaire périodique. Cette forme triangulaire est asymétrique avec un long coté 11 et un petit coté 12. Le long coté 11 de la découpe passe le long des premiers bords latéraux 9 séparant chaque paire de flans. Le petit coté 12 de la découpe passe entre deux parties des bords inférieurs 7 de flans de paires adjacentes le long de la bande, par exemple entre les bords inférieurs des flans 6a et 5b.The Figure 2 allows to visualize the longitudinal cutting line 13 of the strip which splits in two each of the pairs of the band to form two sub-bands of blanks aligned in the same direction in each sub-band. The longitudinal cutting line has a periodic sawtooth / triangular shape. This triangular shape is asymmetrical with a long side 11 and a small side 12. The long side 11 of the cut passes along the first side edges 9 separating each pair of blanks. The small side 12 of the cut passes between two portions of the lower edges 7 of blanks of adjacent pairs along the band, for example between the lower edges of the blanks 6a and 5b.

On a en outre représenté les deux traits 14 de découpage des étroites lignes 4 de matériau le long des deux bordures 2, 3 de la bande 1. Dans d'autres modalités de réalisation, ces étroites lignes de matériau qui sont découpées n'existent pas ou une seule est prévue le long d'une seule des deux bordures.The two lines 14 for cutting the narrow lines 4 of material have also been represented along the two edges 2, 3 of the strip 1. In other embodiments, these narrow lines of material which are cut do not exist. or only one is provided along only one of the two borders.

A noter que la Figure 7 permet de visualiser l'application de l'invention à la réalisation de deux paires de flans sur la largeur d'une bande, un trait de découpe longitudinal linéaire, droit, 14' le long de la bande étant prévu vers le milieu de la bande pour séparer les paires de flans. On abouti en cours de procédé à la réalisation de quatre sous-bandes de flans alignés.Note that the Figure 7 allows to visualize the application of the invention to the production of two pairs of blanks over the width of a strip, a longitudinal linear cutting line straight, 14 'along the strip being provided towards the middle of the strip to separate the pairs of blanks. In the course of the process, four aligned lined subbands were produced.

La Figure 4 permet de mieux voir la relation du petit coté 12 du trait de découpe longitudinal 13 par rapport aux bords des flans de la paire 5a-6a et de la paire 5b-6b de flans. Le trait de découpe dans son petit coté 12 passe à distance des parties correspondantes de bords inférieurs 7 des flans 6a et 5b et il en résulte que si l'on souhaite obtenir un flan dont les limites correspondent bien aux différents bords, il sera nécessaire de couper les surplus de matière de part et d'autre du petit coté 12 et de la partie du bord inférieur 7 correspondant. Dans des variantes de réalisation on déplace le petit coté 12 du trait de découpe 13 pour le faire coïncider au mieux avec un des bords inférieurs des deux flans en correspondance. Dans d'autres modalités, on laisse le surplus de matière sur le/les bords inférieurs dans la jupe, dans une variante on peut le replier sous la jupe.The Figure 4 allows to better see the relationship of the short side 12 of the longitudinal cutting line 13 relative to the edges of the blanks of the pair 5a-6a and the pair 5b-6b of blanks. The cutting line in its small side 12 passes away from the parts corresponding to lower edges 7 of the blanks 6a and 5b and it follows that if it is desired to obtain a blank whose limits correspond to the different edges, it will be necessary to cut the surplus material on both sides of the small side 12 and the part of the corresponding lower edge 7. In alternative embodiments, the small side 12 of the cutting line 13 is moved to coincide with one of the lower edges of the two corresponding blanks. In other embodiments, the excess material is left on the lower edge (s) in the skirt, alternatively it can be folded under the skirt.

De préférence et comme représenté Figure 4, les zones de raccord entre le petit coté 12 et le grand coté 11 du trait de découpe longitudinal sont arrondies 26. Dans des variantes elles sont anguleuses.Preferably and as shown Figure 4 , the connection areas between the short side 12 and the long side 11 of the longitudinal cutting line are rounded 26. In variants they are angular.

Cette découpe longitudinale 13 est obtenue par mise en oeuvre d'un appareil de découpage en continu avec rouleau et contre-rouleau tournants entre lesquels la bande circule. Au moins un du cylindre et du contre-cylindre comporte au moins une empreinte de découpage. Des moyens de synchronisation de la rotation des rouleau et contre-rouleau avec des motifs imprimés 25 de la bande ou autres dispositifs réalisés sur la bande sont mis en oeuvre. A cette fin, des repères peuvent être imprimés ou réalisés le long des deux bordures 2, 3 de la bande 1 comme représenté Figure 5.This longitudinal cutout 13 is obtained by using a continuous cutting apparatus with rotating rollers and against rollers between which the band is circulated. At least one of the cylinder and the counter-cylinder has at least one cutting cavity. Means for synchronizing the rotation of the roll and counter roll with printed patterns of the web or other devices made on the web are implemented. For this purpose, marks may be printed or made along the two borders 2, 3 of the strip 1 as shown Figure 5 .

La Figure 3 schématise les traits de découpe transversaux 15 permettant de séparer les flans des uns des autres.The Figure 3 schematizes the transverse cutting lines 15 for separating the blanks from each other.

Sur la Figure 6, la machine de fabrication des coiffes reçoit des flans individuels résultant des découpages longitudinal et transversal de la bande de matériau dans une ou plusieurs autres machines d'amont. De préférence, une sous-bande de flans alignés est reçue et placée dans une machine d'aval (représenté symboliquement en 15) pour découpage transversal et éventuelle mise au format des flans individuels qui arrivent en 16. La machine de fabrication des coiffes comporte une série de cônes de formages 22 sur lesquels les flans sont enroulés en 17 puis le sommet de la jupe 23 ainsi obtenue est formé par des appuis de formage en 18. Ensuite, en 19, un outil de dépose de rondelle de tête est mis en oeuvre et un formage de ladite tête en 20 par un appui de formage afin d'obtenir la coiffe 24 qui est éjectée de la machine de fabrication des coiffes.On the Figure 6 the machine for manufacturing the caps receives individual blanks resulting from the longitudinal and transverse cuts of the web of material in one or more other upstream machines. Preferably, a subband of aligned blanks is received and placed in a downstream machine (represented symbolically at 15) for transverse cutting and possible formatting of the individual blanks that arrive at 16. The machine for manufacturing the caps comprises a series of forming cones 22 on which the blanks are wound at 17 and the top of the skirt 23 thus obtained is formed by forming supports 18. Then, at 19, a head washer removal tool is implemented and forming said head at 20 by a forming support to obtain the cap 24 which is ejected from the machine for making the caps.

Bien entendu la présente invention n'est pas limitée aux modes de réalisation particuliers qui viennent d'être décrits, mais s'étend à toutes variantes et équivalents conformes à l'étendue des revendications. Ainsi, on comprend bien que l'invention peut être déclinée selon de nombreuses autres possibilités sans pour autant sortir du cadre défini par les revendications. Par exemple le petit coté du triangle périodique du trait de découpage périodique triangulaire asymétrique longitudinal est dédoublé pour mettre directement au format les parties des bords inférieurs des flans correspondants. Dans des variantes, le long du long coté du trait de découpage périodique triangulaire asymétrique longitudinal est dédoublé pour séparer les flans de chaque paire par une mince ligne de matière.Naturally, the present invention is not limited to the particular embodiments described above, but extends to all variants and equivalents according to the scope of the claims. Thus, it is clear that the invention can be declined according to many other possibilities without departing from the scope defined by the claims. For example, the small side of the periodic triangle of the longitudinal asymmetric triangular periodic cutting line is split in order to directly format the portions of the lower edges of the corresponding blanks. In variants, along the long side of the triangular periodic cutting line Asymmetric longitudinal is split to separate the blanks of each pair by a thin line of material.
