An automatic centering device for a conveyor belt for industrial and/or agricultural machinery looped around at least two tensioning rollers characteristically comprises: a detection system which generates a signal correlated to a transversal movement of the belt in a direction relative to its reference position centered on the two rollers; actuator means which drive the rotation of at least one of the two rollers in a plane parallel to the main plane in which the belt lies; a control unit, with the input connected to the detection system and the output connected to the actuator means. The control unit continuously implements a procedure which involves at least, in succession, a step of acquiring and processing the signal, a step of comparing the signal processed with a predetermined threshold value, and, if the threshold value is exceeded, a step of activating the actuator means in which the two rollers are made to converge on the side opposite that of the transversal movement of the belt by a predetermined angle relative to their starting configuration for a predetermined time, to promote a transversal movement of the belt in the opposite direction and return it to its reference position.
An automatic centering device for a conveyor belt for industrial and/or agricultural machinery, the belt being of the type looped around at least two tensioning rollers, the device comprising:
An industrial machine equipped with a conveyor belt of the type looped around at least two tensioning rollers, the industrial machine comprising a guard enclosing the space inside the belt and a pump blowing a compressed gaseous substance into the space inside the belt, keeping the pressure in the space inside the belt higher than outside and preventing the entry of impurities and dirt from outside.
An agricultural machine equipped with a conveyor belt of the type looped around at least two tensioning rollers, the agricultural machine comprising a guard enclosing the space inside the belt and a pump blowing a compressed gaseous substance into the space inside the belt, keeping the pressure in the space inside the belt higher than outside and preventing the entry of impurities and dirt from outside.
