  • Patent number: 8025143
    Abstract: The distribution table (3) is arranged downstream of an introduction table (2) and upstream of single file channels (12) and comprises an entry zone (10) which is provided at the sides with sensors (17) which detect the presence of bottles and connected to control means for controlling and regulating the introduction flow of said bottles at said entry zone (10) and also between said entry zone (10) and the single file channels (12) and distribution channels (11) of transverse alignment the number of which corresponds to half the number of single file channels (12). The distance separating channels (11) from the channels (12) is of the order of one quarter of the diameter of the bottles. The distribution channels (11) are defined by longitudinal walls (21) supported by a mobile structure (15), said structure being moved in a continuous circular sweep of low amplitude in front of said single file channels (12).

  • Patent number: 4880103
    Abstract: A pressureless conveyor for objects, bottles or similar items, including an input conveyor having single-channel paddle chains, a slowdown conveyor having a guide ramp, and an output conveyor with multiple juxtaposed channels. This conveyor includes a distribution system attached to the slowdown conveyor guide ramp for, imparting a serpentine path to the bottles on the output conveyor. More particularly, this distribution system transforms the straight-line motion of the bottles on the slowdown conveyor into an alternating movement combined with the progression of the different paddle chains of the output conveyor. This results in the distribution of the bottles over the entire working surface of the output conveyor.
