Description

Procédé pour la décoration par marquage de surfaces planes ou complexes Method for decoration by marking flat or complex surfaces
La présente invention concerne, de façon générale, la décoration de surfaces planes ou de surfaces complexes, c'est-à-dire s'étendant dans les trois dimensions de l'espace, par un procédé industriel de marquage. Ce procédé s'applique à la décoration de surfaces pouvant appartenir à des objets en matières diverses : métal, matière plastique, bois, matière textile, etc. Plus particulièrement, l'invention est applicable au marquage décoratif par coloration d'articles scolaires et de bureau, dits de "papeterie", un exemple particulier étant le marquage décoratif des ciseaux, notamment des lames métalliques de ciseaux.The present invention relates, in general, to the decoration of flat surfaces or complex surfaces, that is to say extending in the three dimensions of space, by an industrial marking process. This process applies to the decoration of surfaces that may belong to objects made of various materials: metal, plastic, wood, textile, etc. More particularly, the invention is applicable to decorative marking by coloring of school and office articles, called "stationery", a particular example being the decorative marking of scissors, in particular metal blades of scissors.
Des techniques de marquage décoratif par sublimation sont déjà utilisées dans les industries de l'automobile et de la lunetterie. D'autres techniques connues, permettant d'obtenir un résultat visuellement équivalent, sont les suivantes :Decorative sublimation marking techniques are already used in the automotive and eyewear industries. Other known techniques, making it possible to obtain a visually equivalent result, are the following:
- la sérigraphie, applicable pour des surfaces planes ou de très grand rayon de courbure ;- screen printing, applicable for flat surfaces or very large radius of curvature;
- la tampographie, utilisable sur des surfaces de toutes formes ; - le marquage par "offset", envisageable uniquement pour des surfaces planes et sur des matériaux du genre papier ou carton.- pad printing, usable on surfaces of all shapes; - the marking by "offset", possible only for flat surfaces and on materials such as paper or cardboard.
Ces diverses techniques permettent d'obtenir une décoration visuellement acceptable, mais les marquages réalisés possèdent une relativement faible adhérence sur leurs surfaces de support, si bien que la tenue dans le temps de tels marquages n'est pas convenablement assurée.These various techniques make it possible to obtain a visually acceptable decoration, but the markings produced have a relatively low adhesion to their support surfaces, so that the resistance over time of such markings is not adequately ensured.
En particulier, les ciseaux et, plus généralement, tous les articles scolaires et de bureau sont soumis à des agressions mécaniques, dues à leur utilisation (propriétés abrasives du papier) ou à leurs conditions de rangement et de transport, par exemple à l'intérieur d'un tiroir ou d'une trousse où ils sont soumis aux frottements et chocs contre d'autres articles ou instruments analogues, notamment si ces derniers sont métalliques. Dans ces conditions, tout marquage décoratif insuffisamment adhérent se dégrade rapidement, voire même disparaît complètement après un certain temps.In particular, scissors and, more generally, all school and office items are subjected to mechanical attack, due to their use (abrasive properties of paper) or to their storage and transport conditions, for example inside a drawer or case where they are subject to friction and impact against other similar articles or instruments, especially if these are metallic. Under these conditions, any insufficiently adherent decorative marking degrades quickly, or even disappears completely after a certain time.
On connaît encore la technique de marquage "au trempé", qui peut convenir techniquement dans le domaine d'application ici concerné, mais dont la mise en œuvre implique des coûts élevés. La présente invention vise à éviter ces inconvénients, en fournissant un procédé de décoration par marquage qui soit applicable à tous genres de surfaces, et qui conduise à l'obtention d'un marquage de grande qualité, non seulement du point de vue de l'effet décoratif mais aussi par sa très bonne adhérence, lui procurant une résistance aux agressions mécaniques et une longue durée de vie, ce procédé restant toutefois économique. Dans le cas particulier de la décoration de lames de ciseaux, l'invention vise aussi à fournir un procédé qui s'intègre aisément dans le processus de fabrication des ciseaux. A cet effet, le procédé pour la décoration par marquage de surfaces planes ou complexes, objet de l'invention, consiste essentiellement à réaliser un vernissage préalable de la surface à décorer, puis à réaliser, sur la surface vernie, une opération de thermo-impression avec utilisation de papier de sublimation, préalablement imprimé avec le décor choisi. Ainsi, l'invention consiste à prévoir une étape préalable de vernissage, indispensable à la décoration proprement dite des surfaces concernées, qui est réalisée par thermo-impression, autrement dit par une opération de sublimation.The "dip" marking technique is still known, which may be technically suitable in the field of application here concerned, but the implementation of which involves high costs. The present invention aims to avoid these drawbacks by providing a decoration method by marking which is applicable to all kinds of surfaces, and which leads to obtaining a high quality marking, not only from the point of view of decorative effect but also by its very good adhesion, providing it with resistance to mechanical aggressions and a long service life, this process however remaining economical. In the particular case of decorating scissor blades, the invention also aims to provide a process which is easily integrated into the process of manufacturing scissors. To this end, the process for decoration by marking flat or complex surfaces, object of the invention, essentially consists in carrying out a prior varnishing of the surface to be decorated, then in carrying out, on the varnished surface, a heat- printing using sublimation paper, previously printed with the chosen decoration. Thus, the invention consists in providing a prior varnishing step, essential for the actual decoration of the surfaces concerned, which is carried out by thermal printing, in other words by a sublimation operation.
Plus particulièrement, cette opération de sublimation s'effectue en appliquant, sur les surfaces préalablement vernies, une pression et une température adaptées, permettant le transfert en phase gazeuse de l'encre, depuis le papier de sublimation vers les surfaces à décorer.More particularly, this sublimation operation is carried out by applying, to the previously varnished surfaces, an appropriate pressure and temperature, allowing the transfer in ink phase of the ink, from the sublimation paper to the surfaces to be decorated.
Quant à l'étape préalable de vernissage, celle-ci comprend avantageusement l'enduction de la surface à décorer avec au moins une couche de peinture blanche, puis le dépôt d'au moins une couche de vernis transparent, avec des phases intermédiaires de séchage et de dégazage, le vernissage étant suivi par une cuisson dans une étuve.As for the prior varnishing step, this advantageously comprises coating the surface to be decorated with at least one layer of white paint, then depositing at least one layer of transparent varnish, with intermediate drying phases. and degassing, the varnishing being followed by cooking in an oven.
Dans le cas particulier d'une application du procédé de l'invention à la décoration de lames de ciseaux, notamment de lames métalliques, ce procédé de décoration intervient après l'usinage des lames de ciseaux, et avant le surmoulage des anneaux sur ces lames par injection d'une matière thermoplastique.In the particular case of an application of the method of the invention to the decoration of scissor blades, in particular of metal blades, this decoration process occurs after the machining of the scissor blades, and before the molding of the rings on these blades by injection of a thermoplastic material.
Le procédé objet de l'invention est décrit ci-après plus en détail, en prenant précisément pour exemple la décoration de lames métalliques de ciseaux. On considère donc ces lames en fin d'usinage, dont l'affûtage est la dernière opération. Une fois l'usinage achevé, les lames sont dégraissées une nouvelle fois, sur une machine de nettoyage par solvant, avant d'engager l'opération de vernissage. L'opération de vernissage est réalisée en plusieurs phases successives, sur une vernisseuse à rouleaux composée de plusieurs ensembles liés mécaniquement.The process which is the subject of the invention is described below in more detail, taking precisely as an example the decoration of metal blades of scissors. These blades are therefore considered at the end of machining, the sharpening of which is the last operation. Once the machining is complete, the blades are degreased again, on a solvent cleaning machine, before starting the varnishing operation. The varnishing operation is carried out in several successive phases, on a roller varnisher composed of several mechanically linked assemblies.
Sur le premier ensemble, les lames dégraissées sont déposées unitairement sur un tapis de convoyage, de telle manière que le sens de la longueur des lames corresponde au sens d'avance du tapis, les lames étant maintenues dans ce sens par des guides latéraux. L'approvisionnement du tapis de convoyage peut être réalisé manuellement, par exemple avec amenée d'une lame toutes les trois secondes.On the first assembly, the degreased blades are individually deposited on a conveyor belt, so that the length direction of the blades corresponds to the direction of advance of the belt, the blades being held in this direction by lateral guides. The conveyor belt can be supplied manually, for example by supplying a blade every three seconds.
Chaque lame passe ensuite sous un rouleau blanchet de largeur adaptée, par exemple égale à 45 mm. Ce rouleau blanchet est, en amont, enduit de peinture blanche en continu par un dispositif de dépose par report, composé d'un encrier et d'un encreur automatique à galet en acier gravé et microporeux. En sortie de ce premier ensemble, la lame est séchée par une buse pneumatique, avant de passer sous un deuxième ensemble analogue, composé d'un encreur et d'un blanchet. L'épaisseur totale de peinture blanche, ainsi déposée sur la lame, est de quelques microns.Each blade then passes under a blanket roller of suitable width, for example equal to 45 mm. This blanket roller is continuously coated with white paint by a transfer deposition device, composed of an inkwell and an automatic ink roller with an engraved and microporous steel roller. At the outlet of this first assembly, the blade is dried by a pneumatic nozzle, before passing under a second similar assembly, composed of an ink pad and a blanket. The total thickness of white paint thus deposited on the slide is a few microns.
La lame enduite de cette peinture est ensuite entraînée en avant par une bande transporteuse de séchage à basse température, et pendant une durée pouvant être comprise entre 40 et 60 secondes. La bande transporteuse de séchage est surmontée par un dispositif émetteur de rayonnement infrarouge, et par une buse pneumatique à faible pression qui facilite le dégazage de l'enduit précédemment déposé, c'est-à-dire l'évaporation des solvants contenus dans la peinture blanche déposée dans les étapes précédentes. Après ce séchage partiel, la lame est transférée sur l'ensemble suivant, où elle repasse sous un double dispositif à encreur et blanchet. Le produit ici déposé est un vernis transparent, l'épaisseur totale de vernis déposé en deux couches successives étant de quelques microns.The blade coated with this paint is then driven forward by a conveyor belt for drying at low temperature, and for a period which may be between 40 and 60 seconds. The drying conveyor belt is surmounted by an infrared radiation emitting device, and by a low pressure pneumatic nozzle which facilitates the degassing of the coating previously deposited, that is to say the evaporation of the solvents contained in the paint. white deposited in the previous steps. After this partial drying, the slide is transferred to the next set, where it passes under a double inking and blanket device. The product deposited here is a transparent varnish, the total thickness of varnish deposited in two successive layers being a few microns.
La lame, ainsi recouverte de vernis, est de nouveau séchée au moyen d'une buse pneumatique. Ensuite, la lame vernie séchée est évacuée sur un plateau interchangeable, supporté par un chariot motorisé à avance mécanisée, enclenchée après détection de la présence de la lame.The blade, thus covered with varnish, is again dried by means of a pneumatic nozzle. Then, the dried varnished blade is discharged on an interchangeable plate, supported by a motorized carriage with mechanized advance, engaged after detection of the presence of the blade.
L'opération de vernissage de la lame est suivie d'un dégazage effectué sur le plateau supporté par le chariot précité.The varnishing operation of the blade is followed by degassing carried out on the plate supported by the aforementioned carriage.
Ensuite, les lames regroupées sont placées dans une étuve, où elles sont soumises à une cuisson, pendant une durée d'environ 15 minutes.Then, the grouped blades are placed in an oven, where they are subjected to cooking, for a period of approximately 15 minutes.
Après cuisson, les lames sont extraites de l'étuve et entièrement refroidies. L'opération de sublimation peut alors intervenir. A cet effet, les lames sont disposées sur une presse de thermoimpression, et recouvertes du papier de sublimation, préalablement imprimé avec un décor prédéfini. La pression et la température appliquées dans la presse assurent le transfert en phase gazeuse de l'encre, depuis le papier vers le vernis précédemment déposé sur les lames de ciseaux. A la suite de cette opération de sublimation, les lames sont de nouveau refroidies, pour être rendues manipulables. Ces lames décorées sont alors prêtes pour l'opération finale de surmoulage des anneaux.After cooking, the blades are extracted from the oven and completely cooled. The sublimation operation can then take place. For this purpose, the blades are placed on a thermo-printing press, and covered with sublimation paper, previously printed with a predefined decoration. The pressure and the temperature applied in the press ensure the transfer in gaseous phase of the ink, from the paper to the varnish previously deposited on the scissor blades. Following this sublimation operation, the blades are again cooled, to be made manipulable. These decorated blades are then ready for the final operation of overmolding the rings.
Il est ainsi possible de décorer les lames de ciseaux, en particulier sur leurs faces extérieures, avec un motif d'une seule couleur ou multicolore, le motif étant géométrique ou quelconque.It is thus possible to decorate the scissor blades, in particular on their outer faces, with a pattern of a single color or multicolor, the pattern being geometric or arbitrary.
La figure unique du dessin annexé représente, en perspective, une paire de ciseaux dont les lames métalliques 2 et 3 sont décorées extérieurement par le procédé de l'invention, avant le surmoulage de leurs anneaux respectifs 4 et 5, et leur assemblage articulé par un axe 6. Le marquage décoratif, apposé par sublimation sur les faces extérieures des deux lames 2 et 3, consiste ici en des plages colorées telles que celles désignées par les repères 7 et 8, de couleurs distinctes et de formes variées.The single figure of the accompanying drawing shows, in perspective, a pair of scissors, the metal blades 2 and 3 of which are decorated externally by the method of the invention, before the overmolding of their respective rings 4 and 5, and their assembly articulated by a axis 6. The decorative marking, affixed by sublimation on the external faces of the two blades 2 and 3, here consists of colored areas such as those designated by the references 7 and 8, of distinct colors and of varied shapes.
On notera que l'effet décoratif obtenu peut être renforcé par le dépôt de couches successives, en créant un effet visuel de "laque chinoise", qui peut seulement être apporté par le procédé de sublimation, tel que décrit précédemment.It will be noted that the decorative effect obtained can be reinforced by the deposition of successive layers, by creating a visual effect of "Chinese lacquer", which can only be provided by the sublimation process, as described above.
Bien entendu, l'invention ne se limite pas au seul mode de mise en œuvre de ce procédé de décoration qui a été décrit ci-dessus, dans le cadre d'une application particulière. Elle en embrasse, au contraire, toutes les variantes respectant le même principe, quels que soient notamment les détails de l'étape de vernissage, quelles que soient encore la nature et la matière des objets ou surfaces à décorer, et quels que soient aussi les couleurs, l'étendue et l'aspect des marquages réalisés. En particulier, les marquages peuvent être purement décoratifs, ou comporter des inscriptions ou signes. Ces marquages peuvent être envisagés sur la totalité de la surface d'un objet, ou seulement sur une partie de ladite surface.Of course, the invention is not limited to the only mode of implementation of this decoration process which has been described above, within the framework of a particular application. On the contrary, it embraces all the variants respecting the same principle, whatever the details of the varnishing step in particular, whatever the nature and the material of the objects or surfaces to be decorated, and whatever the colors, extent and appearance of the markings made. In particular, the markings can be purely decorative, or include inscriptions or signs. These markings can be envisaged on the entire surface of an object, or only on a part of said surface.
Ainsi, le procédé de l'invention est applicable à la décoration ou au marquage des objets ou articles suivants :Thus, the method of the invention is applicable to the decoration or the marking of the following objects or articles:
- autres parties des ciseaux, en particulier leurs anneaux ;- other parts of the scissors, in particular their rings;
- cutters, avec décoration du corps et/ou des lames, le marquage pouvant ici comporter des décorations colorées et aussi une mention de sécurité ;- cutters, with decoration of the body and / or blades, the marking can here include colored decorations and also a safety notice;
