Descripción de la invenciónDescription of the invention

Para paliar los problemas arriba enunciados se presenta el sistema de dosificación y aplicación de colores, objeto de la presente patente de invención.To alleviate the problems mentioned above, presents the dosing system and application of colors, object of the present invention patent.

Distribuidos alrededor de una fresa esférica o cónica se sitúan las barras de pigmento en polvo aglutinado. La fresa pulveriza las barras, que junto con el aire procedente de la entrada de aire crea una corriente de aire y polvo en dirección a la aguja de la punta del pulverizador, donde se mezcla con el líquido pulverizado, saliendo el pigmento, el líquido y el aire mezclados hacia la superficie a decorar.Distributed around a spherical strawberry or Conical are bonded powder pigment bars. The strawberry pulverizes the bars, which together with the air coming from the air inlet creates a stream of air and dust in the direction of the spray tip needle, where it mixes with the liquid sprayed, leaving the pigment, liquid and air mixed towards the surface to decorate.

El sistema admite tantas barras de colores como se desee. Estas barras de pigmento en polvo aglutinado, al avanzar hacia la fresa giratoria se pulverizan y el polvo resultante sale hacia el exterior. Las barras son movidas mediante motores eléctricos, estando la velocidad de los motores controlada por ordenador, de tal modo que mediante éste se controla la dosificación del pigmento. Mediante la velocidad relativa de los motores que hacen avanzar las minas se controla el color, según aumente o disminuya la velocidad. También se controla el caudal de agua, según la velocidad de avance del émbolo del dosificador de líquido y su distancia a la superficie a decorar se regula el tamaño de la línea. Igualmente se dispone de un cargador automático de barras de pigmento, que permite que cuando una de las barras de pigmento se termine, se pasea la siguiente.The system supports as many color bars as is desired. These bonded powder pigment bars, as you go towards the rotating mill they are pulverized and the resulting powder comes out outward. The bars are moved by motors electrical, the motor speed being controlled by computer, so that it controls the pigment dosage. By the relative speed of the engines that advance the mines the color is controlled, according to increase or decrease speed. The flow rate of water, depending on the feed rate of the dosing piston liquid and its distance to the surface to be decorated regulates the line size. There is also an automatic charger of pigment bars, which allows when one of the bars of Pigment is finished, the next one is walked.

Si movemos, bien la estructura del cabezal, que es el conjunto formado por el pulverizador y la fresa esférica o cónica, bien la superficie a decorar, en las tres dimensiones del espacio con una estructura mecánica adecuada, estando también su movimiento controlado por motores eléctricos gobernados desde un ordenador, tendremos que el sistema puede ejecutar un recorrido programado junto con un color deseado, y por tanto, representar cualquier imagen que se desee.If we move, well the head structure, which is the set formed by the sprayer and the spherical milling cutter or conical, well the surface to decorate, in the three dimensions of the space with a suitable mechanical structure, also being its movement controlled by electric motors governed from a computer, we will have that the system can run a tour programmed together with a desired color, and therefore, represent Any image you want.

Mediante este sistema se consigue representar cualquier imagen que se desee sobre todo tipo de superficies, preferentemente del tipo cerámico, reuniendo las características de cambio dinámico de color y grosor de linea deseados.Through this system it is possible to represent any desired image on all types of surfaces, preferably of the ceramic type, meeting the characteristics of Dynamic color change and line thickness desired.

The coming air from the entrance (121) creates a stream of air and dust in the direction to the tip of the sprayer (11) where it mixes with the liquid sprayed, and from the tip of the sprayer (11) is by where the pigment, the liquid and the air go to the surface to decorate or paint

El funcionamiento del pulverizador se basa en que el líquido que sale del dosificador (3) pasa por un tubo de diámetro reducido, con una aguja en su interior. Alrededor de este tubo hay una corona muy fina que por donde sale el aire, produciendo la pulverización del líquido dosificado por el émbolo (50), evitando el goteo que se produciría en el caso de caída libre del líquido sin el empuje del aire.The operation of the sprayer is based on the fact that the liquid leaving the dispenser (3) passes through a tube of reduced diameter, with a needle inside. Around this tube there is a very fine crown where the air comes out, producing spraying the liquid dosed by the plunger (50), avoiding the dripping that would occur in the case of free fall of the liquid without the air thrust.

Todos los movimientos descritos son controlados por el ordenador (2) a través de motores eléctricos. De este modo, hay un motor eléctrico (servo-motor, paso a paso, etc.) para el movimiento de cada uno de los ejes XYZ del movimiento bien del cabezal, bien de la superficie a decorar, otro para el dosificador (3), otro para el movimiento propio de la fresa (12), y tantos (servo-motores, paso a paso, etc.) como barras de pigmento (20) se encuentren.All described movements are controlled by the computer (2) through electric motors. In this way, there is an electric motor (servo motor, step by step, etc.) for the movement of each of the XYZ axes of the movement either the head, the surface to decorate, another for the dispenser (3), another for the proper movement of the milling cutter (12), and as many (servo motors, step by step, etc.) as Pigment bars (20) meet.
