Combination weighing apparatus with stagger discharge

摘要

The present invention relates to a combination weighing apparatus for selecting a combination of some of weighing hoppers (6i) accommodating therein articles that have been supplied thereto, which combination results in a combination calculated value (Wc) of measured weights of the articles (M) contained in some of the weighing hoppers (6i) forming the combination, falling within a predetermined combination tolerance, and for subsequently discharging the articles (M) in the selected weighing hoppers (6i). In accordance with a condition of a flow of the articles (M) on a falling route downstream of the combination weighing apparatus (1), discharge timing for discharging the articles (M) from the hoppers (6i) is automatically changed among the hoppers (6i). It is thereby possible to promptly detect abnormality in the flow of the articles and to maintain the high operativity and productivity (yield) of the combination weighing apparatus (1). <IMAGE>
