Abstract
Description
L'objet de l'invention fait référence à une lame décapeuse, utilisée dans des machines pour vernir des feuilles de métal pour éviter que du vernis ne soit déposé sur la face intérieure de cette feuille.The object of the invention refers to a scraper blade, used in machines for varnishing metal sheets to prevent varnish from being deposited on the inner face of this sheet.
Dans l'actuel état de la technique, différents équipements pour vernir des feuilles de métal sont connus. Dans les dossiers
Dans la technologie connue, les lames décapeuses sont métalliques. Un problème non résolu de ces lames décapeuses métalliques se présente quant à l'usure qu'ils produisent à cause du frottement dans le cylindre qu'ils nettoient et avec lequel, nécessairement, ils doivent être en contact en permanence pour réaliser cette tâche.In the known technology, the scraper blades are metallic. An unsolved problem of these metal scraper blades arises as to the wear they produce because of friction in the cylinder they are cleaning and with which, necessarily, they must be in constant contact to perform this task.
Un autre problème non résolu des lames décapeuses métalliques est leur courte durée de vie en machine ; c'est-à-dire qu'il faut les retirer très fréquemment pour les aiguiser, ce qui suppose un grand nombre d'heures de travail pour changer et aiguiser les lames.Another unresolved problem of metal scraper blades is their short machine life; that is to say, they must be removed very frequently to sharpen them, which supposes a large number of hours of work to change and sharpen the blades.
Les tâches de remplacement du cylindre s'avèrent très complexes et laborieuses, avec une perte de temps de travail conséquente de la machine. La lame décapeuse, conformément à l'invention, ne produit pas d'usure à cause du frottement dans le cylindre qu'elle nettoie ; de sorte que, quand un remplacement est nécessaire à cause de l'usure, la lame est changée plus rapidement, ce pourquoi les pertes de temps de travail de la machine sont minimales.The tasks of replacing the cylinder are very complex and laborious, with a consequent loss of work time of the machine. The scraper blade according to the invention does not produce wear because of the friction in the cylinder that it cleans; so that when a replacement is necessary because of the wear, the blade is changed more quickly, which is why the machine's working time losses are minimal.
Le demandeur a contrôlé de manière expérimentale que les lames de travail en plastique durent en machine davantage d'heures de fonctionnement avant qu'il ne faille les retirer pour les aiguiser à nouveau. D'autre part, l'aiguisage des lames en plastique est plus coûteux et celles-ci requièrent beaucoup moins de temps d'aiguisage pour obtenir le tranchant nécessaire.The Applicant has experimentally tested that the plastic working blades last longer in machine hours before they have to be removed to sharpen them again. On the other hand, sharpening plastic blades is more expensive and these require much less sharpening time to get the necessary sharpness.
La lame décapeuse, conformément à l'invention, est constituée de matériau non métallique et sa dureté est toujours inférieure à celle du cylindre qu'elle nettoie. Particulièrement, elle présente une configuration mono-pièce pourvue de conformations conjuguées avec celles de la machine où elle est montée (avec des moyens d'ancrage connus).The scraper blade, according to the invention, is made of non-metallic material and its hardness is always less than that of the cylinder that it cleans. In particular, it has a single-piece configuration provided with conformations in conjunction with those of the machine where it is mounted (with known anchoring means).
À partir de cette conception de base, toutes réalisations n'altérant pas, ni ne changeant ou ne modifiant pas le fondement proposé sont incluses dans l'objet de l'invention ; c'est-à-dire que la dureté de la lame est toujours inférieure à la dureté du cylindre qu'elle nettoie.From this basic design, all embodiments that do not alter or change or modify the proposed basis are included in the subject of the invention; that is to say that the hardness of the blade is always less than the hardness of the cylinder that it cleans.
Pour cette raison, le contenu de la présente demande constitue une invention nouvelle impliquant une activité inventive, pouvant être appliquée dans le secteur industrielle.For this reason, the content of the present application is a new invention involving an inventive step, which can be applied in the industrial sector.
Dans le but de mieux comprendre l'objet de la présente invention, une forme préférentielle de réalisation pratique, susceptible de changements accessoires ne dénaturant pas son fondement est représentée sur les plans.
- La
figure 1 représente une vue générale schématique en plan d'une lame décapeuse pour vernisseuses de feuilles de métal, conformément à l'invention. - La
figure 2 représente une vue/coupe générale de profil, correspondante à la figure précédente. - La
figure 3 représente une coupe de profil selon l'indication A:A de lafigure 1 , donnée par une des conformations d'ancrage (11).
- The
figure 1 is a schematic overall plan view of a scraper blade for metal sheet coaters according to the invention. - The
figure 2 represents a profile view / cross section, corresponding to the previous figure. - The
figure 3 represents a profile section according to the indication A: A of thefigure 1 given by one of the anchoring conformations (11).
Sur les deux figures, les moyens d'ancrage de la lame à la machine ont été omis, bien que les conformations d'ancrage (11) soient visibles, disposées à cet effet sur le corps (1) de la lame.In both figures, the means for anchoring the blade to the machine have been omitted, although the anchoring conformations (11) are visible, arranged for this purpose on the body (1) of the blade.
Ci-dessous est décrit un exemple de réalisation pratique, non limitatif, de la présente invention. D'autres modes de réalisation dans lesquels sont introduits des changements accessoires ne dénaturant pas son fondement ne sont absolument pas écartés ; au contraire, la présente invention comprend aussi toutes ses variantes.Below is an example of a practical, non-limiting embodiment of the present invention.

Conformément à l'invention, et selon la réalisation représentée, cette lame décapeuse pour vernisseuses de feuilles de métal se structure dans un corps mono-pièce (1) en matériau non métallique, qui définit en lui-même les conformations nécessaires (11) pour un ancrage opérationnel à la machine.According to the invention, and according to the embodiment shown, this scraper blade for metal sheet coaters is structured in a single-piece body (1) of non-metallic material, which defines in itself the necessary conformations (11) for an operational anchorage to the machine.
Particulièrement, le matériau dont est fait la lame, conformément à l'invention, est du plastique dur ; bien que dans l'objet de l'invention sont inclus la réalisation du corps (1) de la lame dans tout matériel de dureté inférieure à celle du matériel dont est fait le cylindre qu'il nettoie.In particular, the material of which the blade is made according to the invention is hard plastic; although in the subject of the invention are included the embodiment of the body (1) of the blade in any material of hardness less than that of the material which is the cylinder that cleans it.
Pour la réalisation représentée, les dites conformations (11) pour ancrer la lame dans la machine sont des fentes/cavités en « U » réalisées sur le bord/arête postérieure (10) du corps (1), opposé au bord/arête (12) qui définit l'angle d'attaque pour le nettoyage.For the embodiment shown, said conformations (11) for anchoring the blade in the machine are slots / cavities in "U" formed on the edge / rear edge (10) of the body (1), opposite the edge / edge (12). ) which defines the angle of attack for cleaning.
Les dimensions sont indistinctes et accessoires aux effets de l'invention : longueur, largeur et épaisseur du corps (1) ainsi que sa relation avec elles.The dimensions are indistinct and incidental to the effects of the invention: length, width and thickness of the body (1) and its relationship with them.
Les matériaux, les dimensions, proportions et, en général, tous les autres détails accessoires ou secondaires n'altérant pas, ni ne changeant ou ne modifiant le fondement proposé pourront être variables.The materials, dimensions, proportions and, in general, any other accessory or secondary details that do not alter or change or modify the proposed basis may vary.
Les termes dans lesquels est rédigé ce mémoire sont véritables et reflètent fidèlement l'objet décrit, ceux-ci devant être entendus dans leur sens le plus vaste et ceci jamais de manière limitative.The terms in which this memoir is written are true and faithfully reflect the object described, which must be understood in their broadest sense and this never in a limiting way.
