ABSTRACT:
To provide a conveyor system for divergence and convergence, which is capable of always satisfactorily diverging or converging articles without regard to their size. When the roller axes 19 are orthogonal to the transport path 9, an article 60 to be transported is transported downstream by the rollers 16 without being sorted. When it is desired to sort the article 60, an angle changing device 30 is actuated to individually change the angles of inclination of the rollers 16, such that those rollers which are disposed in the upstream region are given a smaller angle of inclination, the angle of inclination being gradually increased. Diversion of the article can be effected such that it has its direction of orientation gradually changed from a smaller angle to a larger angle while it is gradually moved to one side by a smaller amount to a larger amount. The article 60 can be subjected not to an early (sharp) diverging action but to a sufficient diverging action; thus, it can always be satisfactorily diverged without regard to its size. It can always be satisfactorily converged by the reverse operation.
