Title (EN) SYSTEM FOR EXTRUDING BEADS OF CEMENTITIOUS MATERIAL FOR A ROBOT USED FOR THE ADDITIVE MANUFACTURING OF COLOURED ARCHITECTURAL STRUCTURES
(FR) SYSTÈME D'EXTRUSION DE CORDONS DE MATÉRIAU CIMENTAIRE POUR ROBOT DE FABRICATION ADDITIVE DE STRUCTURES ARCHITECTURALES COLORÉES
Abstract:
(EN) The invention relates to a system for extruding beads of cementitious material for a robot used for the additive manufacturing of architectural structures, comprising: an extrusion head (30) for extruding beads of cementitious material, comprising an inlet mouth (31), an outlet nozzle (34) and a mixing chamber (35); and a feed circuit (20) for feeding cementitious material to the extrusion head (30), comprising a storage reservoir (10), a feed conduit (21) and a booster pump (22). The system is characterised in that it further comprises a device (40) for colouring the cementitious material present in the extrusion head (30), comprising at least one reservoir of colour pigments (41a, 41b, 41c), at least one colourization conduit (48a, 48b, 48c) opening into the mixing chamber (35), each colourization conduit (48a, 48b, 48c) being equipped with means for adjusting the quantity of pigments injected into the mixing chamber (35), such that the adjustment means can be operated in a coordinated manner in order to define the colour of the bead of cementitious material extruded through the outlet nozzle (34).
(FR) L'invention concerne un système d'extrusion de cordons de matériau cimentaire pour robot de fabrication additive de structures architecturales comprenant : une tête d'extrusion (30) de cordons de matériau cimentaire comprenant une bouche d'entrée (31), une buse de sortie (34), et une enceinte de mélange (35); un circuit d'alimentation (20) en matériau cimentaire de ladite tête d'extrusion (30) comprenant un réservoir de stockage (10), une conduite (21) d'alimentation, et une pompe de gavage (22), caractérisé en ce qu'il comprend en outre un dispositif de colorisation (40) du matériau cimentaire présent dans ladite tête d'extrusion (30) comprenant au moins un réservoir de pigments de couleur (41a, 41b, 41c), au moins une conduite de colorisation (48a, 48b, 48c) débouchant dans ladite enceinte de mélange (35), chaque conduite de colorisation (48a, 48b, 48c) étant équipée de moyens de réglage de la quantité de pigments injectés dans ladite enceinte de mélange (35), de sorte qu'une commande coordonnée des moyens de réglage permet de définir une couleur du cordon de matériau cimentaire extrudé par ladite buse de sortie (34).
