摘要： A weighing system for making a predetermined weight of a product comprised of individual articles having variable weights by selecting the product stored in a combination of a predetermined number of storage cups. Quantities of the product having targeted weights are distributed to a plurality of scale-controlled hoppers for accurate weighing. The weighed product is fed from each of the scale-controlled hoppers to a plurality of storage cups associted with each of the hopers, and the product weight associated with each storage cup is registered. Specific combinations of storage cups are tested to determine whether the combined product weights therein add to make the desired weight, within acceptable limits. The first combination found to make the weight is used, and the appropriate storage cups are emptied to a container for receiving the product. The appropriate storage cups are refilled from the scale, and the process repeats. When none of the combinations of the preselected number of storage cups include a total product weight within the acceptable limits, the limits are broadened and the cycle repeats. The weighing system includes a programmed microprocessor for controlling operation thereof, for providing the combination to be tested, for calculating the combined weights, and for determining whether the combined weight falls within the acceptable limits. A specific distributor for the product includes a reversing rotating portion for preventing clogging of the product at openings provided for chutes connecting the distributor to the scale-controlled hoppers.
摘要翻译：一种称量系统，用于通过选择以预定数量的存储杯的组合存储的产品来制造具有可变重量的单个制品的产品的预定重量。具有目标重量的产品的数量被分配到多个尺度控制的料斗上以进行精确的称重。将称量的产品从每个秤控料斗进料到与每个所述梭子相关联的多个储存杯中，并且与每个储存杯相关联的产品重量被记录。测试存储杯的特定组合以确定其中的组合产品重量是否在可接受的限度内增加所需的重量。发现使用重量的第一个组合，并将适当的储存杯排空到用于接收产品的容器中。从秤上重新填充合适的储存杯，重复该过程。当预选数量的存储杯的组合中没有一个包括总产品重量在可接受限度内时，限制被扩大并且循环重复。称重系统包括用于控制其操作的编程微处理器，用于提供要测试的组合，用于计算组合的重量，以及用于确定组合重量是否在可接受的限度内。该产品的特定分配器包括一个反转旋转部分，用于防止产品堵塞开口，该开口用于将分配器连接到按比例控制的料斗上。
