  • Patent number: 5590602
    Abstract: A conveyor system includes; a plurality of article carriers; a process conveyor for supporting and transporting the article carriers past the given location at a first speed; an overhead power and free transport conveyor for transporting the article carriers from a loading area at a second speed that differs from the first speed; and a load conveyor adapted for engaging the article carriers and for transporting the engaged article carriers from the transport conveyor to the process conveyor at a speed that is varied during transport by the load conveyor in such a manner that the article carriers are so positioned on the process conveyor that there is a predetermined separation distance between adjacent positioned article carriers. A reroute conveyor is coupled to the process conveyor for retransportation by the process conveyor. Transport by the conveyors is interrupted when a measured speed of article carrier movement past the given location is outside of a given range.

  • Patent number: 5396074
    Abstract: An article irradiation system includes a radiation source disposed along a horizontal axis; a plurality of article carriers; a process conveyor for supporting and transporting the article carriers past the radiation source at a first speed; an overhead power and free transport conveyor for transporting the article carriers from a loading area at a second speed that differs from the first speed; and a load conveyor adapted for engaging the article carriers and for transporting the engaged article carriers from the transport conveyor to the process conveyor at a speed that is varied during transport by the load conveyor in such a manner that the article carriers are so positioned on the process conveyor that there is a predetermined separation distance between adjacent positioned article carriers. A reroute conveyor is coupled to the process conveyor for transporting those article carriers carrying articles that have received radiation impinging upon only the first side of the articles.
