El carro 49 se acciona mediante unos medios de accionamiento adecuados 60. Dichos medios comprenden un motor engranado 62 en cuyo eje de salida están fijadas dos poleas 62 y 62', cada una de las cuales se acopla en una correa 62, cuyos extremos están fijados en las guías 492.The car 49 is operated by means of suitable drive 60. Said means comprise a motor geared 62 on whose output shaft two pulleys 62 and 62 ', each of which is coupled on a belt 62, whose ends are fixed on guides 492.
El bastidor móvil completo 40 se controla mediante un procesador que proporciona el movimiento de toda la unidad, de manera continua o a intervalos discretos, por encima de la boca superior de una tolva 200 para recibir los polvos mezclados, de manera que se depositen dichos polvos en dicha tolva en una secuencia preestablecida o aleatoria.The complete mobile frame 40 is controlled through a processor that provides the movement of all the unit, continuously or at discrete intervals, above the upper mouth of a hopper 200 to receive the powders mixed, so that said powders are deposited in said hopper in a preset or random sequence.
En el funcionamiento de la invención, mientras la unidad completa se desplaza por encima de la tolva 200, los polvos depositados de manera continua en la parte inferior 2 se someten a distintas operaciones de mezclado que pueden ser delicadas, más o menos constantes, o prolongadas según el ajuste predominante en el momento.In the operation of the invention, while the complete unit moves over the hopper 200, the dusts deposited continuously in the bottom 2 are undergo different mixing operations that can be delicate, more or less constant, or prolonged depending on the setting predominant at the moment.
En general, antes de la deposición de los polvos en la tolva 200, se produce un primer mezclado en el momento de dicha deposición, según las posiciones de los elementos de distribución 3 tanto uno con respecto al otro como con respecto a la parte inferior 2, y según la velocidad de rotación de este último; un segundo mezclado en la hoja desviadora en la que la masa entrante se somete a un determinado giro alrededor de su dirección de deslizamiento; y un (posible) fraccionamiento/mezclado dentro del cilindro 5.In general, before the deposition of powders in hopper 200, a first mixing occurs at the time of said deposition, according to the positions of the elements of distribution 3 both with respect to each other and with respect to the bottom 2, and according to the rotation speed of this latest; a second mixed in the diverter sheet in which the dough incoming is subjected to a certain turn around its direction Sliding; and a (possible) fractionation / mixing within the cylinder 5.
Según una variante de la invención, dichos elementos de distribución 3 están asociados con un sistema robotizado, no representado puesto que es de tipo conocido, que durante la deposición de polvo en la placa giratoria 2 varía su posición con respecto a dicha placa giratoria, de manera continua o a intervalos predeterminados, con el fin de diversificar la manera de mezclar los polvos.According to a variant of the invention, said distribution elements 3 are associated with a system robotic, not represented since it is of known type, which during the deposition of dust on the turntable 2 varies its position with respect to said turntable, continuously or at predetermined intervals, in order to diversify the way of mixing the powders.
En otra variante de la invención, representada en la figura 6, por lo menos un rodillo 100 está asociado con dicha placa, para compactar la mezcla de polvo corriente arriba de la abertura de descarga 12. Se hace girar dicho rodillo mediante un motor engranado 101. Sin embargo en determinadas aplicaciones de la invención el rodillo puede montarse libre con el fin de obtener efectos estéticos particulares.In another variant of the invention, represented in figure 6, at least one roller 100 is associated with said plate, to compact the powder mixture upstream of the discharge opening 12. The roller is rotated by means of a geared motor 101. However, in certain applications of the invention the roller can be mounted free in order to obtain particular aesthetic effects
