COMBINATION WEIGHING APPARATUS

摘要

The weighing apparatus includes a feeder which temporarily accommodates materials to be weighed and delivers them when required and a number of weighing hoppers which have a number of storing rooms composed as one body. A number of weiging devices are provided and weigh independently the materials to be weighed accommodated in the storing rooms. A controller calculates either the value of partial weight of materials to be weighed in each storing room based on the signals from the weigher or the number of materials to be weighed calculated from the values of partial weight. The controller combines either values to select such combination that provides a value approximate or equal to a predetermined weight or number. These selected materials are delivered from the storing rooms.
