ABSTRACT:
An automatic device for sorting flat articles comprises a casing with a vertical sorting drum in the center, said drum being provided with posts arranged around the periphery of said drum which are intermittently turned by a drive. Each post has a manipulator sliding freely over said post and having a catch for fixing said manipulator in the uppermost position. The sorting drum is provided with a memory unit with memory cells, each of said cells being made in the form of a group of arms controlled by electromagnets of an actuating mechanism and assembled on a vertical axle under each of said posts, the number of said arms corresponding to the number of flat articles to be sorted and stops, said stops being installed on each sorting position level with said arm which corresponds to the number of the sorted group, each catch being controlled by any one arm of the memory cell of the memory unit, thereby ensuring the distribution of the sorted flat articles in piles around the periphery of said casing in accordance with the parameters of said articles to be sorted.
