  • the cleaning device can be retracted from the cabin ceiling side or from the side by opening the door-shaped flaps to form the pre- and / or post-coating locations. After the doors and slots have been closed, it can then cause the interior walls of the cabin to be cleaned in the working position.
  • the invention therefore aims to provide a powder coating booth of the generic type, which allows fully automatic cleaning of the cabin interior in a space-saving manner as well as, in a preferred manner, automatic cleaning of the automatic cleaning device itself.

Abstract

L'invention a pour objet une cabine de pulvérisation (1) en forme générale de colonne, présentant un couvercle (4) et un fond sensiblement plan (2), ainsi qu'un dispositif de nettoyage (15; 15'; 15''; 15''', 15'''') mobile dans le sens de la hauteur de la cabine, pour nettoyer automatiquement au moins les surfaces des parois intérieures de la cabine. La cabine (1) peut être munie de volets (8) en forme de portes pour des emplacements de pré-application et de post-application (44, 45), ainsi que d'une fente obturable permettant le passage de dispositifs de pulvérisation (43). La cabine (1) présente un fond ouvrable (2) et le dispositif de nettoyage est placé, en position d'attente, au moins en partie au-dessous du fond (2). Ce fond peut être un fond divisé (20, 21) ou peut être complètement retiré ou encore être réalisé sous la forme d'un fond pivotant (40, 40'). Plus avantageusement, le logement situé sous le fond (2), servant à ranger le dispositif de nettoyage (15; 15'; 15''; 15'''; 15'''') en position d'attente, est réalisé sous la forme d'un compartiment de nettoyage fermé (29, 29'), de sorte que ledit dispositif de nettoyage (15; 15'; 15''; 15'''; 15'''') peut être lui-même nettoyé une fois l'intérieur de la cabine nettoyée. En outre, on spécifie les dimensions et les agencements correspondants des moyens de déplacement en hauteur (17; 17'; 17''; 17'''; 17'''') pour le dispositif de nettoyage (15; 15'; 15''; 15'''; 15'''').
