<p>A singulator device for flat rectangular postal objects coated with transparent film in which a pack of postal objects is fed to a singulator system (10) provided with a motor-driven withdrawing belt (19) for withdrawing individually the postal objects from a front face of the pack and feeding them along an unloading path (L). A first barrier of n emitter/receiver sensors C (C0, C1, C2, ... . C n ) is set aligned along the unloading path and is designed to detect the movement of edges of the postal object along the unloading path and a second barrier of m emitter/receiver sensors F (F0, F1, F2, ... . F m ) is set aligned along the unloading path and is designed to detect passage of the edges of the transparent rectangular envelope containing the postal object along the unloading path. Electronic means are provided, designed to control the motion of the withdrawing belt (19) as a function of the signals coming from the first barrier and from the second barrier for creating a constant gap between the transparent rectangular envelopes of the postal objects singulated in succession.</p> |
