Abstract
The device serves for stacking hollow objects generally tapered and intended for accumulation in stacks where they are arranged, each one partially inserted in the next. The stacking device operates at the exit of a rotating machine (20) operating at high speed, and having a rotating head (21) for the single objects, and comprise an extractor means (30) located in an exit station (B) of the rotating machine (20) intended to remove the objects from the rotating head (21) one at a time. According to the invention, an intermediate stacking means (40) is foreseen, fed at its entry point with objects introduced by means of the extractor means (30) with a movement parallel to the axis (R) of the objects in question, said intermediate stacking means (40) being adapted to grip the objects in the position in which they are received from the extractor means (30) and to send them in a longitudinal direction parallel to their axis (R) and at such a speed that, in relation to the feeding speed of the objects in question at the entry, the objects are accumulated in a partial manner, while maintaining a distance that prevents any substantial contact between the side walls (11) of the objects.
