The parcel distributor is a modular set with additional storage module in the form of a ceiling box set on a corner box to which it is rigidly connected and coupled by a cantilever lift mounted in a vertical shaft formed in the support rack frames in both boxes. In each module, between their cantilever racks, there is an electrically driven Cartesian manipulator. On the Cartesian manipulator trolley, there is a grabbing mechanism for taking trays from the front or rear cantilever rack. The window for sending and collecting parcels in the distributor is a locker, preferably in the operating panel, which has an electrically lifted lock cooperating with a ratchet lock and limit switches blocking its lower position when the locker door is open.
