A method of weighing and an apparatus therefor, wherein articles varying in unit weight are continuously weighed by a single weighing machine to classify them into three ranks, one for articles having error weights outside the allowable error limits, another for articles having error weights plus-oriented inside the allowable error limits and the other for articles having error weights minus-oriented inside the allowable error limits, said articles having error weights outside the allowable error limits being rejected, said articles having plus-oriented and minus-oriented error weights inside the allowable error limits being separately pooled and their weights or error weights being allotted to two shift registers and memorized therein in correspondence to the pooling order, and arithmetic operations for combinations of said memorized values are performed to provide a combination of weights equal or most approximate to a predetermined weight. Other merits and details of the construction will be made clear.
A method of automatically weighing a plurality of articles having varying weights to produce a collection of said articles meeting a predetermined total weight of a group of the articles comprising weighing each of the articles in a single weighing zone;
An article handling apparatus for weighing a plurality of articles having varying weights to produce a collection of the weighed articles which will substantially meet a predetermined selected weight for a group of such articles comprising a weighing station, means for feeding the articles of varying weights to said weighing station one at a time, electrical means for memorizing the weight of each individual article as it is weighed, an article separating station positioned at the discharge end of the weighing station, said separation station including a first reject station, a second allowable weight plus section, a third allowable weight minus section, and discharge means adjacent each section for passing a weighed article, dependent on its weight value, to one of the three aforementioned sections, article accumulation means associated with said second weight plus station and said weight minus section for receiving selected articles therefrom, means for selectively receiving from the memorizing means the combination of weight values of the individual articles in the second and third sections which approximate the desired predetermined total weight of a plurality of articles, means actuated by said selectively receiving means for discharging the individual articles from the first and second sections or combinations thereof whose weight values have been selected as approximating the predetermined total weight into the article accumulating means, and means for erasing the weight value of each of the articles selected to make up the collection of articles passed to the article accumulating means from the electrical memorizing means.
