Title
(EN) SYSTEM FOR POWDER COATING FOR ELEMENTS TO BE COATED OF CONSIDERABLE LENGTH
(FR) SYSTÈME POUR REVÊTEMENT DE POUDRE POUR ÉLÉMENTS À REVÊTIR DE LONGUEUR ÉLEVÉE
Abstract
(EN)
The invention discloses a system (I) for powder coating elements to be coated of considerable length, characterised in that it comprises, within an overall occupied floor space (800), a safety area (50) dedicated to the work activities of personnel, exhibiting a zone dedicated to the stage of loading (100) and a zone dedicated to the stage of unloading (600) the finished elements (1) from the overhead conveyor line (2), said safety area (50) marking the perimeter of a single, central block (101) exhibiting the activities of the production process and the specific units predisposed thereto and identified as a unit (200) dedicated to the pre-treatment of the elements to be coated, a unit (300) dedicated to the drying of the elements to be coated and a unit (500) for the polymerisation of coating powders deposited on the elements to be coated, there being further provided a unit (400) dedicated to coating and an overhead conveyor line (2) for the elements to be coated (1) that extends with a winding path. The invention further discloses a procedure for coating elements to be coated of considerable length (1), characterised in that it provides a coating booth (401) that has a triangular plan schematically identified by a first, a second and a third vertex (A, B and C), and a conveyor line (2) for the elements (1) that enters a side (BC) and extends along a path that brings said elements to be coated (1) toward said first vertex (A) and then returns and has said elements to be coated (1) exit from said side (BC) in a substantially symmetrical position with respect to said first vertex (A), said path being configured so that the elements to be coated (1), in transit in the booth, encounter direct spraying by sets of electrostatic spray guns (10 and 11), and coating powder, which, given that it has not directly deposited on said elements to be coated (1), travels toward a vertical suction inlet (12) located at said first vertex (A), and encounters the array of profiles in transit prior to being suctioned.

La présente invention concerne un système (I) pour revêtir de poudre des éléments à revêtir de longueur élevée, caractérisé en ce qu'il comprend, dans un espace au sol globalement occupé (800), une zone de sécurité (50) dédiée aux activités de travail du personnel, présentant une zone dédiée à l'étape de chargement (100) et une zone dédiée à l'étape de déchargement (600) des éléments finis (1) depuis la ligne de convoyeur aérien (2), ladite zone de sécurité (50) marquant le périmètre d'un bloc central unique (101) présentant les activités du processus de production et les unités spécifiques prédisposées pour celui-ci et identifiée comme une unité (200) dédiée au prétraitement des éléments à revêtir, une unité (300) dédiée au séchage des éléments à revêtir et une unité (500) pour la polymérisation de poudres de revêtement déposés sur les éléments à revêtir, dans laquelle il est disposé une unité (400) dédiée au revêtement et une ligne de convoyeur aérien (2) pour les éléments à revêtir (1) qui s'étend avec un chemin sinueux. L'invention concerne en outre une procédure pour revêtir des éléments à revêtir de longueur élevée (1) caractérisée en ce qu'elle comprend une cabine de revêtement (401) qui a un plan triangulaire schématiquement identifié par un premier, un deuxième et un troisième sommet (A, B et C), et une ligne de convoyeur (2) pour les éléments (1) qui entre d'un côté (BC) et s'étend le long d'un chemin qui amène lesdits éléments à revêtir (1) vers ledit premier sommet (A) et retourne ensuite et amène lesdits éléments à revêtir (1) à sortir par ledit côté (BC) dans une position sensiblement symétrique par rapport audit premier sommet (A), ledit chemin étant configuré de sorte que les éléments à revêtir (1), en transit dans la cabine, subissent une pulvérisation directe par des ensembles de pistolets de pulvérisation électrostatique (10 et 11), et la poudre de revêtement, qui, étant donné qu'elle n'a pas été directement déposée sur lesdits éléments à revêtir (1), se déplace vers une entrée d'aspiration verticale (12) située audit premier sommet (A), et rencontre l'agencement de profilés en transit avant d'être aspirée.
