Device for controlling and regulating the spacing of parcels, packages or similar objects and, more particularly, of postal parcels, mounted at the outlet of a separation apparatus that includes a truncated cone-shaped rotating drum with its axis inclined towards the horizontal and having internal helical fins designed to deliver the packages one by one to the outlet of the drum. The device further includes a conveyor belt driven at constant speed and onto which the packages are tipped at the outlet of the drum, a barrier of detection cells, the beam of which extends in perpendicular to the line of travel of the conveyor in order to identify the moment of each package's passage into this beam and to measure, between two successive interruptions of the cells, the relative spacing of two consecutive packages intersecting, each in turn, the beam of the cells. The device further includes at least one instantaneous photographic camera to obtain an image illustrating the distribution in real time of the packages on the conveyor, a digital-processing circuit to process the image supplied by the camera to identify any superimposition or juxtaposition of two packages which have escaped detection by the cells, and a deviator mechanism actuated by the processing circuit to remove from the conveyor those packages which are not suitably spaced.
Device for controlling and regulating spacing of packages positioned to receive the packages from the outlet of a separation apparatus comprising a truncated cone-shaped rotating drum with its axis inclined horizontally and comprising internal helical fins designed to deliver the packages individually to the outlet of the drum, said device comprising a conveyor belt driven at constant speed and onto which the packages are provided from the outlet of the drum, a row of detection cells the collective beam of which extends perpendicularly across a portion of the conveyor for identifying the movement when each of the packages passes into this beam and for measuring, between two successive interruptions of the beam, the relative spacing of two successive packages, at least one video means to provide an image illustrating the distribution in real time of the packages on the conveyor, a processing circuit to process the image supplied by the video means to identify any superimposition of juxtaposition of at least two packages which have escaped detection by the cells, and a mechanism actuated by the processing circuit to remove from the conveyor those packages which are not suitably spaced.
