Abstract: 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.

Abstract: Control device for a flow of objects in continuous file and, more particularly, of postal parcels or packages, prior to their introduction into a separator mechanism which imposes at its oulet a suitable spacing between one object and the next, which comprises a first conveyor belt on which the objects are disposed in bulk, this conveyor travelling at a variable linear speed (V1), a second conveyor belt, disposed following the first and driven at a similarly variable linear speed (V2), a photographic camera for the acquisition in real time of an image of the second conveyor and of the packages transported by it, presenting according to the length of the conveyor a given longitudinal dimension (L), a processing circuit for the image received from the camera in order to discern within this image the number of packages (Nc) which it contains, a computer for controlling the instantaneous speeds (V1 and V2) of the two conveyors during the transfer of the packages disposed on the second conveyor according to the di
