machine for sorting and stacking stacks of containers of different heights and of individual containers with folding walls, capable of forming stacks with a height suitable for palletizing, consisting of a single supply line (A),from one or more conveyor belts, from a recording station (B),from at least one committee band (X),consists of at least two stacking units (C1, C2, C3) provided at the outlet of storage lines (4e) and downstream of the guides of a common descent band (E), marked by the fact that the only supply line (A) is the recording station (B),All stacking units (C1, C2, C3) and the committee band (X) operate that for the transfer of the feeder line (A) to the committee band (X) respectively. the individual stacking units (C1, C2, C3) or individual containers (2a) acting across the supply line (A) acting as restraints (20b, 21b, 22b, 23b) (20c, 21c, 22c, 23c) and then sliding (20, 21, 22, 23) acting (20a, 21a, 22a, 23a) and that the movement (2a) of the conveyor belt of the supply line (A) during the operations of the recording station (B),continues during the action of the restraint bars (20c, 21c, 22c, 23c) and during the action of the sliders (20, 21, 22, 23), whereas for the time of holding and handing over a stack or a single container tothe corresponding stacking unit is blocked only if the distance to the next stack or container covered by the photoelectric barrier (2f) in the range of the recording station (B) is minimal.
