  • Patent number: 8237067
    Abstract: A checkweigher for the in-motion weighing of objects being transported along a conveyor line. A checkweigher of the present invention employs a plurality of scales each having its own set of weighing conveyor elements. For example, a first scale may be associated with a set of lighter weight chains to convey and weigh smaller objects, while a second scale may be associated with a set of heavier weight chains to convey and weigh larger objects. This design essentially allows the incorporation of a lightweight and heavyweight checkweigher within one common checkweigher frame. The problem of noise caused by one set of conveyor elements associated with one scale affecting the accuracy of the other scale(s) is eliminated by locating the conveying surfaces of the conveyor elements associated with the individual scales in different planes. Thus, objects transported by one weighing conveyor exert no load on the conveyor elements of the other weighing conveyor(s).
