  • Patent number: 11375743
    Abstract: A transferring and inspection unit for transferring and inspecting a group of elongated elements that are rod-shaped for smoking articles that includes a forming pocket, having a longitudinal axis, which is provided with a hollow housing suitable for housing a group of elongated elements to be inspected; a transporting conveyor of the forming pocket which is configured to advance the pocket along an advancing path through a first inspection position; a first tridimensional inspecting optical assembly configured to perform in respective successive scanning instants a plurality of first tridimensional optical scans by projecting a first light blade over a first head face of the group, during advancing of the forming pocket through the first inspection position; a processing device configured to obtain, for each first tridimensional scan, a respective first scanning line associated with the respective scanning instant and to reconstruct a first tridimensional profile of the first head face on the basis of the pl

  • Patent number: 10302418
    Abstract: An inspection group is proposed for inspecting cylinder-shaped elongated elements for smoking articles, in which a working plane is selected passing through a longitudinal axis of a first elongated element and there are considered a first half space and a second half space arranged on opposite parts with respect to the working plane.

  • Patent number: 10299506
    Abstract: A method is proposed for inspecting cylinder-shaped elongated elements for smoking articles that provides projecting from a first half-space a first stripe of light onto an external face of a first elongated element and projecting from a second half-space onto the first elongated element a second stripe of light. The method reconstructs, by means of a first identified curved line and a second identified curved line respectively in a first acquired view and in a second acquired view of the first elongated element, a first closed curved section profile of the first elongated element and identifies possible deformations of the reconstructed first closed curved profile with respect to an ideal section profile.

  • Patent number: 7779846
    Abstract: Groups of cigarettes approaching a packer are transferred and inspected by a conveyor equipped with receptacles advancing along a set path, and an inspection device such as will verify the presence and the integrity of each cigarette in each receptacle and generate signals to indicate the outcome of the inspection. The conveyor also incorporates emitters in the form of permanent magnets, each associated with a relative receptacle and interacting with a receiver consisting in an array of magnetoresistors ordered along the conveying path; the receiver is capable of emitting signals synchronized with the steps of the inspection procedure and indicating the position of each receptacle relative to a fixed inspection position.
