Machine for dry decoration of ceramic tiles, with a control system for a ceramic mixture accumulation

Abstract

A machine for dry decoration of ceramic slabs or tiles, comprising: —a deposit plane (); —a distributor unit (D), arranged to dispense, in a controlled manner, a ceramic compound in granular or powdered form, formed by two or more different ceramic materials; —a storage container (F), interposed between the distributor unit (D) and the deposit plane () to store a certain quantity of ceramic compound dispensed by the distributor unit (D), and comprising an unloading opening (O) arranged to allow the deposit of the ceramic compound on the deposit plane (); wherein the storage container (F) and the deposit plane () are in relative movement with respect to one another along a longitudinal direction (Y); —a control module, connected to the distributor unit (D) and arranged to control and regulate the dispensing of ceramic compound by the distributor unit (D); The machine comprises one or more sensors (S), connected to the control module and arranged to detect a significant parameter of the quantity of ceramic compound contained in the storage container (F) and to process a corresponding measurement signal; The control module is arranged to regulate the dispensing of ceramic compound as a function of the measurement signal received, so as to maintain a desired amount of ceramic compound inside the container (F).
