por debajo de un valor mínimo, es probable que se dé una situación de "flotación" de los paquetes de chatarra introducidos. La pared 30 se mueve entonces automáticamente entre la tercera posición y la segunda o cuarta posición (Figuras 5 y 7) y posteriormente vuelve a la posición inicial, es decir, a la tercera posición. Cuando la presión detectada por los transductores alcanza un valor máximo, correspondiente a una presión de sobrecarga producida por un exceso de chatarra entre los rodillos 52, 54, el último se mantiene en rotación en dicho estado de presión durante un tiempo previamente ajustado, por ejemplo 3 s, al final de los cuales las bombas impulsoras se reajustan a cero de acuerdo con una rampa de descarga previamente ajustada. Entonces se invierte la contrarrotación de los rodillos 52, 54 (direcciones F3, F4), pasando de una velocidad de rotación cero a una velocidad de rotación máxima de acuerdo con una rampa de aceleración predeterminada, por ejemplo gradual. Below a minimum value, it is likely that there will be a situation of "flotation" of the introduced scrap packages. The wall 30 then automatically moves between the third position and the second or fourth position (Figures 5 and 7) and subsequently returns to the initial position, that is, to the third position. When the pressure detected by the transducers reaches a maximum value, corresponding to an overload pressure produced by an excess of scrap between the rollers 52, 54, the latter is kept in rotation in said pressure state for a previously set time, for example 3 s, at the end of which the impeller pumps are reset to zero according to a previously adjusted discharge ramp. The counter rotation of the rollers 52, 54 (directions F3, F4) is then reversed, moving from a zero rotation speed to a maximum rotation speed according to a predetermined acceleration ramp, for example gradual.

Al mismo tiempo la pared 30 se mueve de la tercera posición a la segunda o cuarta posición determinando el rasgado, por medio de protuberancias de tipo gancho 40, de esa parte de la chatarra que ha provocado el estado de sobrecarga. At the same time the wall 30 moves from the third position to the second or fourth position determining the tearing, by means of hook-type protuberances 40, of that part of the scrap that has caused the state of overload.

Al final de un intervalo de tiempo predeterminado, la pared 30 vuelve a la tercera posición y los rodillos 52, 54 comienzan a rotar de nuevo en la dirección de fragmentación (F1, F2), pasando de la velocidad cero a la velocidad máxima de acuerdo con una rampa de aceleración previamente ajustada, que provoca que la chatarra así tratada se aplaste y se mueva hacia la salida de descarga 24. At the end of a predetermined time interval, the wall 30 returns to the third position and the rollers 52, 54 begin to rotate again in the direction of fragmentation (F1, F2), moving from zero speed to maximum speed according with a previously adjusted acceleration ramp, which causes the scrap so treated to crush and move towards the discharge outlet 24.

Programa para el aplastamiento preliminar de chatarra suelta Program for preliminary crushing of loose scrap

Los rodillos 52, 54 rotan en la dirección de rotación de fragmentación normal (F1, F2), la pared 30 se coloca en la posición inactiva (Figura 4), que es óptima para el tratamiento de chatarra suelta. The rollers 52, 54 rotate in the direction of normal fragmentation rotation (F1, F2), the wall 30 is placed in the inactive position (Figure 4), which is optimal for the treatment of loose scrap.

Si, durante al menos 15 s consecutivos, u otro intervalo de tiempo predeterminado, los valores de presión detectados por los transductores relativos en los circuitos hidráulicos que impulsan los rodillos 52, 54 permanecen por debajo de un valor mínimo predeterminado, es probable que se dé una situación de "flotación" de la chatarra suelta introducida. La pared 30 se mueve entonces automáticamente entre la posición inactiva y la tercera posición, quedándose en la tercera posición durante al menos 5 s, por ejemplo, y vuelve luego a la posición inicial, es decir, la posición inactiva. If, for at least 15 consecutive s, or another predetermined time interval, the pressure values detected by the relative transducers in the hydraulic circuits that drive the rollers 52, 54 remain below a predetermined minimum value, it is likely to be given a "flotation" situation of the loose scrap introduced. The wall 30 then automatically moves between the inactive position and the third position, remaining in the third position for at least 5 s, for example, and then returns to the initial position, that is, the inactive position.

Cuando la presión detectada por los transductores de presión alcanza un valor máximo, correspondiente a una presión de sobrecarga producida por un exceso de chatarra entre los rodillos 52, 54, el último se mantiene en rotación en dicho estado de presión durante un tiempo previamente ajustado, por ejemplo 3 s, al final de los cuales las bombas impulsoras relativas se reajustan a cero de acuerdo con una rampa de descarga previamente ajustada. Entonces se invierte la contrarrotación de los rodillos 52, 54 (direcciones F3, F4), pasando de una velocidad de rotación cero a una velocidad de rotación máxima de acuerdo con una rampa de aceleración predeterminada, por ejemplo gradual. When the pressure detected by the pressure transducers reaches a maximum value, corresponding to an overload pressure produced by an excess of scrap between the rollers 52, 54, the latter is kept in rotation in said pressure state for a previously set time, for example 3 s, at the end of which the relative drive pumps are reset to zero according to a previously adjusted discharge ramp. The counter rotation of the rollers 52, 54 (directions F3, F4) is then reversed, moving from a zero rotation speed to a maximum rotation speed according to a predetermined acceleration ramp, for example gradual.

Al mismo tiempo la pared 30 se mueve de la posición inactiva a la segunda o cuarta posición determinando el rasgado, por medio de protuberancias de tipo gancho 40, de esa parte de la chatarra que ha provocado el estado de sobrecarga. At the same time the wall 30 moves from the inactive position to the second or fourth position determining the tearing, by means of hook-type protuberances 40, of that part of the scrap that has caused the overload state.

Al final de un intervalo de tiempo predeterminado, la pared 30 vuelve a la primera posición inactiva y los rodillos 52, 54 comienzan a rotar de nuevo en la dirección de fragmentación (F1, F2), pasando de la velocidad cero a la velocidad máxima de acuerdo con una rampa de aceleración previamente ajustada, provocando que la chatarra así tratada se aplaste y se mueva hacia la salida de descarga 24. At the end of a predetermined time interval, the wall 30 returns to the first inactive position and the rollers 52, 54 begin to rotate again in the direction of fragmentation (F1, F2), moving from the zero speed to the maximum speed of according to a previously adjusted acceleration ramp, causing the scrap so treated to crush and move towards the discharge outlet 24.

Programa semiautomático de chatarra en forma mixta Semi-automatic scrap program in mixed form

El programa semiautomático lo controla e inspecciona visualmente un operario. La pared 30 se coloca en la posición inactiva (Figura 4), independientemente del tipo de chatarra que se vaya a tratar. The semi-automatic program is controlled and visually inspected by an operator. The wall 30 is placed in the inactive position (Figure 4), regardless of the type of scrap metal to be treated.

Los rodillos 52, 54 rotan en la dirección de rotación de fragmentación normal (F1, F2), la pared 30 se coloca en la posición inactiva. Por medio del panel de mando, por ejemplo un control por radio, el operario puede intervenir durante el funcionamiento automático de los rodillos 52, 54 a su discreción, impulsando la palanca de mando, para mover la pared 30 manualmente de la posición inactiva a la segunda, tercera o cuarta posición, por ejemplo de manera continua y basándose en el estado real de introducción de la chatarra, para evitar posibles estados de "flotación". Cuando el operario libera la palanca de mando esto determina la vuelta automática de la pared 30 a la posición inactiva. The rollers 52, 54 rotate in the direction of normal fragmentation rotation (F1, F2), the wall 30 is placed in the inactive position. By means of the control panel, for example a radio control, the operator can intervene during the automatic operation of the rollers 52, 54 at his discretion, by pushing the control lever, to move the wall 30 manually from the inactive position to the second, third or fourth position, for example continuously and based on the actual state of introduction of scrap metal, to avoid possible "flotation" states. When the operator releases the joystick this determines the automatic return of the wall 30 to the inactive position.

Cuando la presión detectada por los transductores de presión alcanza un valor máximo, correspondiente a una presión de sobrecarga producida por un exceso de chatarra entre los rodillos 52, 54, el último se mantiene en rotación en dicho estado durante un tiempo previamente ajustado, por ejemplo 3 s, al final de los cuales las bombas impulsoras relativas se reajustan a cero de acuerdo con una rampa de descarga previamente ajustada. Entonces se When the pressure detected by the pressure transducers reaches a maximum value, corresponding to an overload pressure caused by an excess of scrap between the rollers 52, 54, the latter remains in rotation in said state for a previously set time, for example 3 s, at the end of which the relative drive pumps are reset to zero according to a previously adjusted discharge ramp.
