ABSTRACT:
The device is adapted for the accumulating of a variable number of objects having a collar (9) in the vicinity of their upper end, in particular plastic bottles (8). The holding of the objects is effected in each row by a flow of air coming from an elongated air conveyor arranged above the path of the objects, having a lower wall provided with a longitudinal slit the edges of which serve as guide for the collar (9) of the objects (8), a blow channel having lateral slits for the flow of the air being placed above the longitudinal slit so that the air acts on the upper end of the objects, causing their displacement. The device comprises a plurality of parallel, independent, separate accumulation rows (2a, 2b, 2c, 2d) which can be placed selectively, in succession, in communication with a distribution path (4) connected to the upstream row (6) and with a collection path (5) connected to the downstream row (7), each accumulation row having furthermore, on the downstream side, a controlled stop device (22a, 22b, 22c, 22d) capable of blocking the displacement of the objects.
