Abstract
Abstract An automatic continuous weighing machine of the belt conveyer type which can weigh a number of articles successively fed thereto, the improvement of which is that plural pairs of endless chains and corresponding weighing units are included, each of the weighing units being operatively coupled to each pair of chains, so that the articles to be weighed are successively put on the different pairs of chains and weighed by the corresponding weighing units without interference with the measurement of the adjoining articles, thereby enabling reduction of the feeding interval of the articles and a corresponding increase of weighing speed and efficiency.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
154 words
An automatic continuous weighing machine, comprising a plurality of endless conveyers driven at the same speed, and a plurality of weighing units, each weighing unit operatively coupled to one of said conveyers, respectively, for sensing weights of articles carried on said conveyers, each of said conveyers including a plurality of endless circulating members arranged in parallel, characterized in that said endless circulating members of the respective conveyers are arranged in mutually parallel intervening fashion, whereby said conveyers each have a common article transporting path, each of said endless circulating members having a plurality of article supporting subsections arranged at predetermined intervals in the lengthwise direction, said article supporting subsections belonging to each conveyer being aligned laterally to form article supporting sections of said conveyer, said article supporting sections of the respective conveyers being arranged sequentially in series along said article transporting path to allow themselves to move at least vertically, independently of each other.
Claim 2
Dependent Claim
