Description

  The present invention performs a combination calculation based on the weight of each article obtained by a plurality of weighing units, selects a combination of weighing units so that the obtained combined weight is close to the target weight, and identifies each combination. The present invention relates to a combination weighing device for display.

  Conventionally, various research and development have been conducted on combination weighing. For example, Patent Literature 1 discloses a combination weighing or counting method configured such that an appropriate operation is performed when a combination failure occurs continuously a predetermined number of times so that the overall operation rate does not decrease.

  Further, for example, Patent Document 2 discloses a manual combination weigher. In the manual combination weigher, when the operator supplies the object to be weighed (product) to the weighing pan and there are two or more combinations that have a predetermined weight or a predetermined number, the first selected weighing is performed. If the product is collected from the plate, the operator automatically displays the next selected weighing pan on the remaining weighing pans after completing the operation without any switch operation. This reduces the work burden on the operator who manually supplies and discharges the product, and does not display the next combination before the product collection operation is completed. Collecting goods can be performed without confusion between the weighing pan selected the second time and the weighing pan selected the second time.
