Abstract
Description
La présente invention concerne le domaine des équipements électroménagers, en particulier des cuisinières, des fours, des lave-vaisselle et des appareils micro-ondes munis d'un ou de plusieurs panneaux verriers en verre trempé, formant généralement des bandeaux de commande, et a pour objet un procédé de réalisation de bandeaux de commande, notamment pour de tels appareils électroménagers.The present invention relates to the field of equipment appliances, in particular stoves, ovens, dishwashers and microwave appliances with one or more glass panes hardened, generally forming control panels, and relates to a process for producing control panels, in particular for such Appliances.
Les éléments verriers utilisés à cet effet sont généralement des pièces d'esthétique décorées par sérigraphie d'émail ou d'encre. Le décor comporte, le plus souvent, un fond de couleur, un logo de marque d'une autre couleur, et des indications de positionnement des boutons de commandes de l'appareil, ainsi que, parfois, des symboles plus ou moins éclairés indiquant l'état de fonctionnement de l'appareil. En conséquence, il est courant d'utiliser plus de deux couleurs sérigraphiées sur un élément verrier devant servir de bandeau de commande d'un appareil.The glass elements used for this purpose are generally pieces of aesthetics decorated by serigraphy of enamel or ink. The decor includes, more often, a colored background, a brand logo of another color, and indications for positioning the control buttons of the device, as well as, sometimes more or less illuminated symbols indicating the operating status of the device. As a result, it is common to use more than two colors screen printed on a glass element to be used as a control panel for a apparatus.
Ces éléments du décor respectent un positionnement précis, soit par rapport aux bords du verre; soit par rapport à des trous prévus dans l'élément verrier et destinés aux boutons de commande ou boutons poussoirs, ou par rapport à l'axe de symétrie du verre.These elements of the decor respect a precise positioning, either by relative to the edges of the glass; either with respect to holes provided in the element glass and intended for control buttons or push buttons, or relative to the axis of symmetry of the glass.
Les symboles, logos, marquages, indications d'état de fonctionnement sont généralement obtenus par des opérations de sérigraphie successives, permettant une impression des couleurs sur le verre, aux endroits souhaités, tout en respectant les positionnements par rapport à l'élément verrier.Symbols, logos, markings, status indications of operation are generally obtained by screen printing operations successive, allowing an impression of the colors on the glass, at the places desired, while respecting the positioning relative to the glass element.
Ces opérations de sérigraphie successives nécessitent, cependant. des réglages de machine, voire des changements d'outils de sérigraphie, ce qui entraíne des temps de réglage et de changement d'outil pénalisant la production et grevant le prix de revient des pièces ainsi réalisées. Ce problème est d'autant plus crucial que les séries de production des pièces d'esthétique sont faibles, du fait même de leur variété, ce afin de couvrir toutes les niches de marché.These successive screen printing operations require, however. of machine settings, even changes of screen printing tools, which results tool setting and change times penalizing production and encumbering the cost price of the parts thus produced. This problem is all the more crucial that the production series for aesthetic parts are low, due to the very fact of their variety, in order to cover all market niches.
Il a également proposé, par EP-A-0 391 848 un procédé de décoration consistant à modifier localement la pigmentation d'une couche de revêtement au moyen d'un faisceau laser. Ce procédé met en oeuvre une couche de revêtement particulièrement adaptée à une décoration ultérieure par faisceau laser et n'est pas utilisable pour une couche quelconque de revêtement. He also proposed, by EP-A-0 391 848 a method of decoration consisting in locally modifying the pigmentation of a layer of coating by means of a laser beam. This process uses a layer of coating particularly suitable for subsequent decoration by laser beam and cannot be used for any coating layer.
Par ailleurs, JP-A-61 108487 décrit un procédé de gravage par faisceau laser, dans lequel le verre est protégé, dans les zones ne devant pas être gravées, par un revêtement protecteur qui est éliminé ultérieurement.Furthermore, JP-A-61 108487 describes a method of engraving by laser beam, in which the glass is protected, in areas that should not be engraved, by a protective coating which is later removed.
Enfin, on connaít, par DE-A-42 02 074 et DE-A-43 20 341 des procédés de nettoyage de surfaces par mise en oeuvre d'un faisceau laser réalisant une destruction des dépôts indésirables.Finally, we know, from DE-A-42 02 074 and DE-A-43 20 341 of surface cleaning methods using a laser beam making destruction of unwanted deposits.
Ces procédés connus ne permettent, cependant, pas la réalisation de décoration sur des surfaces en verre préalablement munies d'une couche sérigraphiée, sans détérioration dudit verre.These known methods do not, however, allow the realization of decoration on glass surfaces previously provided with a layer screen printed, without deterioration of said glass.
La présente invention a pour but de pallier ces inconvénients en proposant un procédé de réalisation de bandeaux de commande, notamment pour appareils électroménagers, permettant l'obtention de bandeaux individuels personnalisés par association à la sérigraphie de décors communs à une gamme de bandeaux d'un décor spécifique.The object of the present invention is to overcome these drawbacks by proposing a method for producing control panels, in particular for household appliances, making it possible to obtain individual blinds personalized by combining screen printing with decorations common to a range of banners with a specific decoration.
A cet effet, le procédé de réalisation de bandeaux de commande, notamment pour appareils électroménagers, consiste essentiellement à réaliser au moins une gravure laser personnalisée sur au moins une sérigraphie déjà appliquée sur un bandeau brut de base en verre, par enlèvement des décors, symboles ou signes correspondants dans la couche sérigraphiée, puis à recouvrir ces gravures d'un enduit de couleur différente, immédiatement à la suite de l'opération de gravure ou lors d'une opération séparée, par un dépôt manuel ou automatisé.To this end, the process for producing control panels, especially for household appliances, essentially consists in carrying out minus a personalized laser engraving on at least one screenprint already applied on a raw basic glass strip, by removing decorations, symbols or corresponding signs in the screen-printed layer, then to cover these engravings a coating of a different color, immediately following the operation of engraving or in a separate operation, by manual or automated filing.
L'invention sera mieux comprise, grâce à la description ci-après. qui
se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif,
et expliqué avec référence au dessin schématique annexé, dans lequel :
Conformément à l'invention, et comme le montrent, à titre
d'exemples, les figures 1 et 2 du dessin annexé, le procédé de réalisation de
bandeaux de commande, notamment pour appareils électroménagers, consiste
essentiellement à réaliser au moins une gravure laser personnalisée de décors,
symboles ou signes 1 et/ou 2 sur au moins une sérigraphie 3 et/ou 4 déjà appliquée
sur un bandeau brut de base 5 en verre. In accordance with the invention, and as shown, by way of
examples, Figures 1 and 2 of the accompanying drawing, the method of making
control panels, in particular for household appliances, consists
essentially to carry out at least one personalized laser engraving of decorations,
symbols or
Ensuite, les gravures correspondant aux décors, symboles ou signes 1
et/ou 2 peuvent être recouvertes d'un enduit de couleur différente, immédiatement
à la suite de l'opération de gravure ou lors d'une opération séparée. par un dépôt
manuel ou automatisé. Ainsi, à titre d'exemple, les décors. symboles ou signes 1
et/ou 2, prévus autour des trous 6 et 7, sont, par exemple, respectivement de
couleur blanche et de couleur rouge.Then, the engravings corresponding to the decorations, symbols or
Selon une caractéristique de l'invention, le bandeau brut de base 5
peut être constitué en verre trempé et la ou les sérigraphies 3 et/ou 4 peuvent être
en émail vitrifié.According to a characteristic of the invention, the basic
La figure 3 du dessin annexé représente un bandeau brut de base 5
muni d'un logo sérigraphié 3, par exemple ABC, sur un fond également
sérigraphié 4, le logo étant d'une couleur donnée et le fond d'une autre couleur, à
savoir, respectivement en gris et en noir. En outre, le bandeau brut 5 peut
également être pourvu de deux trous 6 et 7.Figure 3 of the accompanying drawing shows a basic
La réalisation de tels bandeaux comportant quatre couleurs
différentes nécessite, actuellement, successivement au moins quatre passages de
sérigraphie et quatre réglages d'écrans. La sérigraphie des décors, symboles ou
signes complémentaires, désignés par les références 1 et 2 sur les figures 1 et 2.
nécessite au moins un passage de sérigraphie, voire deux, supplémentaire, selon
que ces décors, symboles ou signes seront ou non de même couleur ou de couleur
différente.The realization of such bands with four colors
currently requires successively at least four passages of
screen printing and four screen settings. The screen printing of the decorations, symbols or
additional signs, designated by the
En outre, une gamme d'appareils électroménagers peut fort bien comporter des bandeaux de même géométrie et perçage, présentant un même fond et un même logo, mais avec des inscriptions et ou d'autres signes, dont les tailles et les couleurs sont différentes, voire qui sont positionnés différemment.In addition, a range of household appliances may well have strips of the same geometry and drilling, with the same bottom and the same logo, but with inscriptions and or other signs, including sizes and the colors are different, or even positioned differently.
Ainsi, l'obtention par sérigraphie des bandeaux selon les figures 1
et 2, n'est possible que par utilisation d'un seul écran de sérigraphie commun, à
savoir celui du logo 3. Les écrans de sérigraphie du fond 4, ainsi que des décors.
symboles ou signes complémentaires, désignés par les références 1 et 2 sur les
figures 1 et 2, ne peuvent pas être communs, de sorte qu'à chaque production de
ces bandeaux, un changement des outils de sérigraphie, avec des temps et, par
conséquent, des coûts de réglage correspondants à imputer à la quantité produite
par lot de chacun des produits.Thus, obtaining by screen printing the strips according to Figures 1
and 2, is only possible by using a single common screen printing screen,
know that of the
L'invention propose de réaliser les bandeaux selon les figures 1 et 2 à
partir d'un bandeau brut 5. A cet effet, les décors, symboles ou signes 1 et/ou 2
sont gravés par une découpe au laser du fond 4. Une telle découpe peut être
réalisée en quelques secondes. Ainsi, les modes de réalisation selon les figures 1
et 2 peuvent être obtenus très rapidement et sans mise en oeuvre d'un outillage
particulier.The invention proposes to produce the strips according to FIGS. 1 and 2 to
from a
L'application de l'enduit de couleur différente dans les gravures
correspondant aux décors, symboles ou signes 1 et/ou du fond 4 sera effectuée
rapidement, soit manuellement ou automatiquement, par exemple avec une encre à
séchage rapide.Applying different color plaster in engravings
corresponding to the decorations, symbols or
La découpe des gravures correspondant aux décors, symboles ou
signes 1 et/ou 2 est avantageusement effectuée par l'intermédiaire d'un laser à
commande numérique. Il en résulte une grande flexibilité en ce qui concerne les
décors, symboles ou signes 1 et 2 à réaliser ainsi qu'une parfaite exécution de ces
décors, symboles ou signes 1 et 2. En outre, le nombre de variantes dans une
gamme devient illimité. Ainsi, le procédé n'a été décrit qu'à propos de la gravure
du fond 4, cependant, la gravure du logo 3 est également réalisable. par exemple
pour effectuer une modification de son aspect. Il est également possible de réaliser
le logo 3 directement sur le fond 4, par gravure laser. Dans un tel cas, seul le
fond 4 serait sérigraphié sur le bandeau brut 5.The cutting of the engravings corresponding to the decorations, symbols or
Le procédé conforme à l'invention permet donc de personnaliser à
l'infini dans un délai très court des bandeaux bruts 5 tenus en stock et pouvant
constituer la base d'une gamme d'éléments verriers de commande d'appareils. Ces
bandeaux bruts étant communs à de nombreuses variantes de bandeaux. ils
peuvent être produits en quantité élevée, avec des coûts réduits pour les séries
produites.The process according to the invention therefore makes it possible to personalize
infinity within a very short time of the
Selon une autre caractéristique de l'invention, le bandeau brut de
base 5 peut être constitué par un verre à couche réfléchissante en face avant. cette
couche réfléchissante étant munie de décors, de symboles ou de signes par gravure
laser, lesdits décors, symboles ou signes pouvant être recouverts d'un enduit de
couleur déposé en face arrière. Ainsi, par cette découpe à des endroits précis, en
plus de la découpe d'émail en face arrière; les décors, symboles ou signes sont
parfaitement mis en exergue, du fait du remplissage des gravures correspondantes
par l'enduit de couleur, sans être atténués par la couche réfléchissante. Ce mode de
réalisation permet d'obtenir des couleurs vives déposées à l'arrière de verres
réfléchissants, remplaçant ainsi des sérigraphies recto et verso sur un même
élément verrier.According to another characteristic of the invention, the raw strip of
La découpe du décor de fond par laser à commandes numériques suivie d'une application de couleur à séchage rapide sur les zones découpées, permet une personnalisation à l'infini des produits, dans un temps court, en quantité même unitaire, de façon répétitive ou non, sans coût d'outillage significatif, ni temps de réglage prohibitif pour des séries faibles.Cutting the background decoration by laser with digital controls followed by a quick-drying color application on the cut areas, allows endless personalization of products, in a short time, while quantity even per unit, repetitively or not, without tooling cost significant, nor prohibitive setting time for weak series.
Grâce à l'invention, il est possible de réaliser, à coût réduit et dans des délais particulièrement courts, par exemple en flux tendu, à la demande, à partir de bandeaux bruts, des bandeaux de commandes d'appareils électroménagers personnalisés pour couvrir des niches de marché.Thanks to the invention, it is possible to produce, at reduced cost and in particularly short deadlines, for example just-in-time, on demand, from raw strips, device control strips custom appliances to cover market niches.
Ces bandeaux bruts, qui peuvent être stockés prêts à être personnalisés, peuvent déjà être munis de leurs éléments de fixations, tels que des équerres, des enjoliveurs collés, des bifaces ou un dépôt de colle. Le procédé permet ainsi d'éviter les délais entraínés par ces opérations de pose et collage. ainsi que par les temps de polymérisation des colles correspondantes.These raw strips, which can be stored ready to be can already be fitted with their fixing elements, such as brackets, glued covers, bifaces or a glue deposit. The process thus avoids the delays caused by these installation and bonding operations. as well as the polymerization times of the corresponding adhesives.
En outre, le procédé conforme à l'invention ne prévoit pas une gravure du verre par laser, mais un simple enlèvement d'une partie de la couche de revêtement sérigraphiée, sans détérioration du verre nuisible à l'esthétique, cette gravure étant suivie d'un dépôt d'une couche d'un revêtement d'une autre couleur.In addition, the method according to the invention does not provide for a glass etching by laser, but a simple removal of part of the layer of screen-printed coating, without deterioration of the glass detrimental to the aesthetics, this etching being followed by deposition of a layer of a coating of another color.
Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit, ni aux bandeaux de fours en verre trempé ou non trempé. Elle peut fort bien s'appliquer à des plans de cuissons en verre également sérigraphiés. Des modifications restent possibles, notamment du point de vue de la conception des pièces brutes devant subir la découpe au laser d'une partie de leur décor, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the embodiment described, nor to the oven or non-tempered glass oven strips. She may very well apply to glass baking plans also screen printed. Of modifications are still possible, particularly from the point of view of the design of raw parts to undergo laser cutting of part of their decoration, without however, depart from the scope of protection of the invention.
