Description

La présente invention concerne un système de support pour une bobine de bande à estamper. L'invention se rapporte à un module dérouleur de bande à estamper, équipé avec au moins un tel dispositif de support pour bobine de bande à estamper. L'invention concerne une machine d'estampage pour la fabrication d'emballages, comprenant au moins un tel dispositif de mise en place de bobine de bande à estamper. L'invention concerne une machine d'estampage pour la fabrication d'emballages équipée avec un module dérouleur comprenant au moins un tel dispositif de mise en place de bobine. L'invention concerne également un procédé de mise en place d'une bobine de bande à estamper dans un module dérouleur de bande à estamper.The present invention relates to a support system for a reel of embossing tape. The invention relates to a tape unwinder module to be stamped, equipped with at least one such support device for a reel of tape to be stamped. The invention relates to a stamping machine for the manufacture of packaging, comprising at least one such device for placing a reel of tape to be stamped. The invention relates to a stamping machine for the manufacture of packaging equipped with an unwinder module comprising at least one such device for placing the coil. The invention also relates to a method for placing a reel of embossed tape in an unrolling tape dispenser module.

Dans le domaine de la fabrication des emballages, par exemple ceux destinés à l'industrie du luxe, une machine de façonnage par estampage dépose par pression des motifs sur un élément en feuille. Les motifs, par exemple des textes et/ou des décorations le plus souvent métallisés, sont obtenus par une forme à estamper ou cliché. Les motifs proviennent de portions d'une pellicule issue d'une ou plusieurs bandes à estamper.In the field of the manufacture of packaging, for example those intended for the luxury industry, a stamping machine press-deposits patterns on a sheet member. The patterns, for example texts and / or decorations most often metallized, are obtained by a stamping or cliché shape. The patterns come from portions of a film resulting from one or more bands to be stamped.

Dans la machine d'estampage, les éléments en feuille sont retirés d'une pile située en amont, saisis par un transporteur, et amenés successivement dans une presse d'estampage à platine porteuse du cliché. Le cliché est monté sur le sommier supérieur fixe de la presse. Une contrepartie d'estampage correspondant au cliché est montée sur le sommier inférieur mobile de la presse. Dans le cas d'un estampage à chaud, connu sous le nom de hot foil stamping, le cliché est chauffé. Les bandes à estamper métallisés sont conduites entre le plan de défilement des éléments en feuille et le sommier supérieur.In the stamping machine, the sheet elements are withdrawn from an upstream stack, picked up by a conveyor, and successively fed into a stamping press with a plate carrying the cliché. The cliché is mounted on the upper fixed base of the press. A stamping counterpart corresponding to the cliché is mounted on the movable lower bed of the press. In the case of hot stamping, known as hot foil stamping, the cliché is heated. The metallized embossing bands are led between the travel plane of the sheet elements and the upper base.

Dans un mouvement vertical de montée, le sommier inférieur mobile va presser la bande à estamper contre chaque élément en feuille entre le cliché et sa contrepartie pour y déposer les portions de pellicule. Une fois le dépôt de pellicule réalisé, le sommier inférieur redescend et l'élément en feuille estampé est ensuite relâché par la barre de pinces sur une pile dans une réception, pour laisser la place au nouvel élément en feuille qui suit.In a vertical upward movement, the movable lower base will press the strip to be stamped against each sheet element between the cliché and its counterpart in order to deposit the portions of film thereon. Once the film deposition has been completed, the lower beam descends and the stamped sheet element is then released by the gripper bar onto a stack in a reception, to make room for the new sheet element that follows.

Dans le même intervalle de temps, la bande à estamper est déplacée de façon à ce qu'une nouvelle surface de pellicule soit mise en correspondance avec le cliché. Le transport des bandes nécessite des moyens de déroulement et d'avance intermittents généralement constitués par des rouleaux contre lesquels les bandes sont pincées par des galets presseurs. L'entraînement motorisé de ces rouleaux permet l'avance intermittente de ces bandes.At the same time interval, the strip to be embossed is moved so that a new film surface is matched with the cliché. The transport of the bands requires means of unwinding and intermittent advance generally constituted by rollers against which the bands are clamped by pressure rollers. The motorized drive of these rollers allows the intermittent advance of these bands.

La majorité des motifs déposés sur les emballages peuvent être réalisés à partir de bandes à estamper de faible laize, n'excédant généralement pas 30cm. Mais il est parfois nécessaire de recourir à des bandes à estamper de plus grande laize, typiquement de l'ordre de 50cm à 140cm. Un ensemble de bandes plus étroites disposées côte à côte et dont la laize totale cumulée atteint cet ordre de grandeur peut également être utilisé.The majority of the designs deposited on the packaging can be made from narrow width stamping strips, generally not exceeding 30cm. But it is sometimes necessary to resort to stamping bands of larger width, typically of the order of 50cm to 140cm. A set of narrower strips arranged side by side and the total cumulative width of which reaches this order of magnitude can also be used.

Chaque bande à estamper est conditionnée sous la forme d'une bobine qui est montée mobile en rotation sur elle-même, et qui est dévidée par l'intermédiaire d'un arbre d'avance ou un baladeur tirant directement sur la bande. Les bobines de bandes à estamper sont stockées dans un module dérouleur. Le module sert à supporter les bobines et à alimenter la machine avec de la ou des bandes. En pratique, cet arbre d'avance est voué à tourner à vitesse variable étant donné que l'avance de bande s'opère de façon séquentielle au sein de la presse à platine à la différence d'un baladeur qui, en production tire en continu sur la bobine. Pour garantir une tension de bande optimale, la bobine est en effet freinée de façon permanente en lui appliquant un couple de freinage dont l'intensité est régulièrement abaissée au fur et à mesure du dévidage. Mais comme la bobine présente une masse et donc une inertie relativement importante, il s'avère particulièrement difficile pour elle de suivre une telle succession d'accélérations, de décélérations et de temporisations.Each strip to be stamped is packaged in the form of a reel which is mounted so as to be able to rotate on itself, and which is unwound by means of an advance shaft or a slide pulling directly on the strip. The reels of tape to be embossed are stored in an unwinder module. The module is used to support the coils and to feed the machine with tape (s). In practice, this advance shaft is doomed to rotate at variable speed given that the web feed takes place sequentially within the platen press unlike a player which, in production, pulls continuously. on the spool. To guarantee optimum tape tension, the reel is in fact permanently braked by applying a braking torque to it, the intensity of which is regularly lowered as it is unwound. But as the coil has a mass and therefore a relatively large inertia, it turns out to be particularly difficult for it to follow such a succession of accelerations, decelerations and delays.

Etat de la techniqueState of the art

L'opérateur est confronté au montage de la bobine ou des bobines dans le module dérouleur. En effet, de telles bobines sont généralement assez lourdes et coûteuse en raison du matériau utilisé pour l'estampage, qui peut typiquement être de l'or ou un autre métal précieux. Le document WO 2013/143664 décrit un système comprenant des moyens de levage. De plus, le document EP 1 588 968 A1 décrit un système de support de bobines tels que défini par le préambule de la revendication 1 et un procédé mise en place d'une bobine. Du fait de leur poids allant jusqu'à 300kg, ces bobines sont donc peu pratiques à mettre en place et l'opérateur court en plus le risque de l'endommager lors de son montage dans le module ce qui n'est pas économiquement acceptables compte tenu de leur coût élevé.The operator is confronted with the assembly of the reel or reels in the unwinder module. This is because such coils are generally quite heavy and expensive due to the material used for stamping, which can typically be gold or another precious metal. The document WO 2013/143664 describes a system comprising lifting means. In addition, the document EP 1 588 968 A1 discloses a coil support system as defined by the preamble of claim 1 and a method for placing a coil. Due to their weight of up to 300kg, these coils are therefore impractical to install and the operator also runs the risk of damaging it during its assembly in the module which is not economically acceptable. given their high cost.

Exposé détaillé des formes de réalisation préféréesDetailed description of the preferred embodiments

La Fig. 1 illustre une vue en perspective d'un module porte-bobine dérouleur 1 dans lequel des bobines 2 et 2' sont installées. Chaque bobine 2 et 2' est montée sur une traverse ou glissière 3, 3' et 3" qui est fixée dans des parois latérales 4 et 4' du module 1. Chaque traverse 3, 3' et 3" porte au moins un système de support pour bobine. Le système de support comprend une paire de supports latéraux réglables 5 et 5'. Les bobines 2 et 2' sont tenues sur chaque traverse 3' et 3" entre les deux supports latéraux 5 et 5'.The Fig. 1 illustrates a perspective view of a reel holder module 1 in which reels 2 and 2 'are installed. Each coil 2 and 2 'is mounted on a cross member or slide 3, 3' and 3 "which is fixed in side walls 4 and 4 'of module 1. Each cross member 3, 3' and 3" carries at least one system of spool holder. The support system includes a pair of adjustable 5 and 5 'side supports. The coils 2 and 2 'are held on each cross member 3' and 3 "between the two side supports 5 and 5 '.

Les bobines 2 et 2' ont dans ce cas plusieurs tailles différentes en fonction de l'estampage à réaliser. L'agencement plusieurs bobines 2 et 2' par traverse 3, 3' et 3" peut également être prévu, par exemple deux ou plus, dans la mesure où la taille de chaque bobine 2 et 2' permet un tel arrangement côte-à-côte. Le choix de l'utilisation d'une ou plusieurs bobines 2 et 2' par traverse 3, 3' et 3" peut être dicté par l'estampage à effectuer.The coils 2 and 2 'in this case have several different sizes depending on the stamping to be produced. The arrangement of several coils 2 and 2 'per cross member 3, 3' and 3 "can also be provided, for example two or more, insofar as the size of each coil 2 and 2 'allows such a side-to-side arrangement. The choice of using one or more coils 2 and 2 'per cross member 3, 3' and 3 "may be dictated by the stamping to be carried out.

Les Figs. 2 et 3 illustrent un premier mode de réalisation non-revendiqué du système de support d'une bobine dans le module 1, sur une traverse 3. Plus précisément, le système de support comprend les deux supports 5 et 5' munis chacun d'un pied 6 et 6' qui se monte sur la traverse 3. Chaque pied 6 et 6' se bloque dans une position choisie grâce à un système de serrage avec vis par exemple. En état desserré, les supports 5 et 5' peuvent se déplacer latéralement sur la traverse 3 pour s'adapter à la taille de la bobine 2.The Figs. 2 and 3 illustrate a first unclaimed embodiment of the system for supporting a coil in module 1, on a cross member 3. More precisely, the support system comprises the two supports 5 and 5 'each provided with a foot 6 and 6 'which is mounted on the crosspiece 3. Each foot 6 and 6' is blocked in a position chosen by means of a tightening system with screws for example. In a loose state, brackets 5 and 5 'can move sideways on cross member 3 to accommodate the size of spool 2.

Les supports 5 et 5' comprennent en outre une paroi ou joue 7 et 7', qui est montée sur les pieds 6 et 6' par exemple par vissage ou soudage ou autre moyen équivalent. Chaque paroi 7 et 7' comprend une arête ou bord supérieur allongé 8 et 8'.The supports 5 and 5 'further comprise a wall or cheek 7 and 7', which is mounted on the feet 6 and 6 'for example by screwing or welding or other equivalent means. Each wall 7 and 7 'comprises a ridge or elongated upper edge 8 and 8'.

Pour porter une bobine 2, une paire de flasques 9 et 9' présentent un axe d'un côté (côté extérieur), qui est destiné à coopérer avec une encoche 10 et 10' ménagée dans la paroi 7 et 7.' De l'autre côté (côté intérieur) des flasques 9 et 9', un moyeu expansif 11 et 11' est utilisé pour solidariser et bloquer chaque flasque 9 et 9' sur l'axe de la bobine 2. Ainsi, une paire de flasques 9 et 9' est montée sur chaque bobine 2 et 2' et est bloquée sur celles-ci grâce au moyeu expansif 11 et 11'.To carry a coil 2, a pair of flanges 9 and 9 'have an axis on one side (outer side), which is intended to cooperate with a notch 10 and 10' formed in the wall 7 and 7. ' On the other side (inner side) of the flanges 9 and 9 ', an expanding hub 11 and 11' is used to secure and block each flange 9 and 9 'on the axis of the coil 2. Thus, a pair of flanges 9 and 9 'is mounted on each coil 2 and 2' and is blocked on them thanks to the expansive hub 11 and 11 '.

Une fois ce montage effectué et lorsque les supports 5 et 5' seront fixés sur la traverse 3, 3' et 3", l'opérateur peut poser la bobine 2 et 2' avec les flasques 9 et 9' sur le rebord 8 et 8' et faire rouler la bobine 2 et 2' vers l'intérieur du module 1 jusqu'à ce que les axes des flasques 9 et 9' rentrent à l'intérieur des encoches 10 et 10' (comme dans les Figs. 2, 4 et 6).Once this assembly has been carried out and when the supports 5 and 5 'are fixed on the crossbar 3, 3' and 3 ", the operator can place the coil 2 and 2 'with the flanges 9 and 9' on the edge 8 and 8 'and roll the spool 2 and 2' towards the inside of module 1 until the axes of the flanges 9 and 9 'fit inside the notches 10 and 10' (as in the Figs. 2 , 4 and 6 ).

Le système de support 5 et 5' comprend également des moyens de freinage. Ces moyens de freinage comprennent un disque 12 attaché à l'axe du flasque 9, et un frein à disque 13 sur lequel agissent une pince 14 et des plaquettes. L'actionnement des plaquettes du frein peut se faire sous pression hydraulique par exemple ou autre moyen équivalent.The support system 5 and 5 'also comprises braking means. These braking means comprise a disc 12 attached to the axis of the flange 9, and a disc brake 13 on which a clamp 14 and pads act. The brake pads can be actuated under hydraulic pressure, for example, or other equivalent means.

Une butée 15 et 15' est prévue sur la paroi 7, du côté opposé à celui de l'encoche 10 et 10'. Comme décrit ci-dessus, des moyens de fixation 16 sont prévus pour bloquer le support 5 et 5' sur la traverse 3, 3' et 3". La butée 15 et 15' sert à éviter un retour et une chute de la bobine 2 hors du système de support 5 et 5'.A stop 15 and 15 'is provided on the wall 7, on the side opposite that of the notch 10 and 10'. As described above, fixing means 16 are provided to block the support 5 and 5 'on the cross member 3, 3' and 3 ". The stop 15 and 15 'serves to prevent a return and a fall of the coil 2 out of the 5 and 5 'support system.

La Fig. 4 illustre un support dans un autre mode de réalisation du système de support 25 et 25' de la présente invention. Dans ce mode, les principes exposés ci-dessus s'appliquent également et la différence réside principalement dans les moyens de freinage utilisés. Des moyens de freinage magnétique 30 sont utilisés.The Fig. 4 illustrates a support in another embodiment of the support system 25 and 25 'of the present invention. In this mode, the principles set out above also apply and the difference lies mainly in the braking means used. Magnetic braking means 30 are used.

Plus précisément, un support 25 comprend notamment les mêmes éléments suivants que celle du premier mode, i.e. un pied 6, des moyens de fixation 16, une paroi 7, un bord 8, et une encoche 10 qui peut être fermée par un rabat pivotant 29 et 29' (Flèche R en Fig. 5).More specifically, a support 25 comprises in particular the same following elements as that of the first embodiment, ie a foot 6, fixing means 16, a wall 7, an edge 8, and a notch 10 which can be closed by a pivoting flap 29 and 29 '(Arrow R in Fig. 5 ).

Les moyens de freinage magnétique 30 comprennent notamment un train de pignons d'engrenage 31, 32, 33 et 34, ainsi qu'un élément magnétique 35 qui coopère et agit sur le dernier pignon 34 pour en moduler la vitesse, et ainsi fonctionne comme un frein pour ralentir la rotation de la bobine 2 et 2'. Les moyens de freinage magnétique 30 comprennent l'élément magnétique 35 qui permet de ralentir le pignon 34, qui est entraîné par le pignon 42 de la flasque 9.The magnetic braking means 30 comprise in particular a train of gear pinions 31, 32, 33 and 34, as well as a magnetic element 35 which cooperates and acts on the last pinion 34 to modulate its speed, and thus functions as a brake to slow down the rotation of the reel 2 and 2 '. The magnetic braking means 30 comprise the magnetic element 35 which makes it possible to slow down the pinion 34, which is driven by the pinion 42 of the flange 9.

Les flasques 9 et 9' comprennent leur moyeu expansif 11 et 11'. La flasque 9 du côté gauche de la figure comprend en plus un pignon axial 42 monté sur son axe 43, le pignon axial 42 étant engrené avec le premier pignon 31 des moyens de freinage 30. Compte tenu de cet engrènement, il est préférable d'utiliser le rabat 29 et 29' pour éviter que la flasque 9 et ainsi la bobine 2 et 2' ne bougent pendant le freinage.The flanges 9 and 9 'include their expanding hub 11 and 11'. The flange 9 on the left side of the figure further comprises an axial pinion 42 mounted on its axis 43, the axial pinion 42 being meshed with the first pinion 31 of the braking means 30. In view of this meshing, it is preferable to use the flap 29 and 29 'to prevent the flange 9 and thus the coil 2 and 2' from moving during braking.

Le fonctionnement général est le même pour les deux modes de réalisation. Le procédé de mise en place de la bobine de bande à estamper 2 dans un module dérouleur 1 d'au moins une bobine de bande à estamper pour une machine d'estampage comprend plusieurs étapes. Une première étape consiste à placer le système de support 5 et 5' ou 25 et 25' sur la glissière 3.The general operation is the same for both embodiments. The method of placing the reel of tape to be stamped 2 in an unwinder module 1 of at least one reel of tape to be stamped for a stamping machine comprises several steps. A first step consists in placing the support system 5 and 5 'or 25 and 25' on the slide 3.

Une deuxième étape consiste à installer les flasques latérales 9 et 9' des deux côtés de la bobine 2.A second step consists in installing the side shields 9 and 9 'on both sides of the coil 2.

Une troisième étape consiste à positionner la bobine 2 sur les deux joues 7 et 7', grâce à l'axe de rotation de chacune des flasques latérales 9 et 9'. Une bobine 2 et 2' avec des flasques 9 et 9' est amenée dans le module 1 et les axes de flasques 9 et 9' sont posés sur le bord 8.A third step consists in positioning the coil 2 on the two cheeks 7 and 7 ', thanks to the axis of rotation of each of the side flanges 9 and 9'. A coil 2 and 2 'with flanges 9 and 9' is fed into module 1 and the flange pins 9 and 9 'are placed on edge 8.

Une quatrième étape consiste à faire rouler la bobine 2 sur les deux joues 7 et 7', et plus précisément sur le bord 8 et 8' des deux joues 7 et 7', jusqu'au niveau des encoches 10 des deux joues 7 et 7'. Les flasques 9 et 9' sont déplacées par exemple par rotation jusqu'à ce que leurs axes soient entrés dans les encoches 10.A fourth step consists in rolling the coil 2 on the two cheeks 7 and 7 ', and more precisely on the edge 8 and 8' of the two cheeks 7 and 7 ', up to the level of the notches 10 of the two cheeks 7 and 7 '. The flanges 9 and 9 'are moved for example by rotation until their axes have entered the notches 10.

Une cinquième étape consiste à insérer l'axe de rotation de chacune des flasques latérales 9 et 9' dans chacune des encoches 10 et 10'. Puis l'axe peut être bloqué dans l'encoche 10 au moyen du rabat 29 et 29'. Ce rabat 29 et 29' est rendu nécessaire dans ce mode d'exécution à cause des moyens de freinage 30 utilisés.A fifth step consists in inserting the axis of rotation of each of the side flanges 9 and 9 'in each of the notches 10 and 10'. Then the axis can be blocked in the notch 10 by means of the flap 29 and 29 '. This flap 29 and 29 'is made necessary in this embodiment because of the braking means 30 used.

Une sixième étape consiste à faire coopérer les moyens de freinage 13 et 30 avec la bobine 2. Dans le premier mode de réalisation, le disque 12 du système de support 5 et 5' vient s'insérer dans la pince 14 des moyens de freinage 13. Dans le deuxième mode de réalisation, le pignon axial 42 des moyens de freinage 30 du système de support 25 et 25' vient s'engrener avec le premier pignon 31 des moyens de freinage 30.A sixth step consists in making the braking means 13 and 30 cooperate with the coil 2. In the first embodiment, the disc 12 of the support system 5 and 5 'is inserted into the clamp 14 of the braking means 13. In the second embodiment, the axial pinion 42 of the braking means 30 of the support system 25 and 25 'meshes with the first pinion 31 of the braking means 30.

La présente invention n'est pas limitée aux modes de réalisation décrits et illustrés. De nombreuses modifications peuvent être réalisées, sans pour autant sortir du cadre défini par la portée du jeu de revendications.The present invention is not limited to the embodiments described and illustrated. Many modifications can be made without departing from the scope defined by the scope of the set of claims.

D'autre type de moyens de freinage peut être utilisé, tels qu'un frein à patin frottant contre l'une des flasques 9. Les bobines de bande à estamper 2 et 2' peuvent être positionnées grâce aux systèmes de support selon l'invention en étant montées les unes au dessus des autres come dans le cas du module dérouleur, ou en étant disposées à l'horizontal directement dans la machine d'estampage, ou encore en étant placées en diagonal.Other type of braking means can be used, such as a pad brake rubbing against one of the flanges 9. The reels of strip to be stamped 2 and 2 'can be positioned thanks to the support systems according to the invention. by being mounted one above the other as in the case of the unwinder module, or by being arranged horizontally directly in the stamping machine, or by being placed diagonally.
