AI Technical Summary

Technical Problem

The configuration of existing combination weighing devices that rotate multiple weighing hoppers around a rotation axis and supply materials from a single location leads to an increase in device size due to the need for a collection chute to collect selected weighing materials, which complicates the discharge path.

Method used

A combination weighing device and system that includes a control circuit to manage the movement and discharge of weighing hoppers into defined regions, allowing for continuous supply of materials while minimizing device size by eliminating the need for a collection chute.

Benefits of technology

The solution enables efficient coordination with feeder systems while suppressing the increase in device size, allowing for continuous material supply and simplifying the discharge path, thereby facilitating appropriate coordination with the feeder systems.

Abstract

In a combined weighing device that rotates multiple weighing hoppers around a rotating axis and supplies weighing materials to multiple weighing hoppers from one location, the present invention provides a combined weighing device and system that can achieve appropriate coordination with a feeder while suppressing an increase in the size of the device. [Solution] The combination weighing device comprises a plurality of weighing hoppers that rotate around a rotation axis, a plurality of weighing instruments provided in each of the plurality of weighing hoppers, and a control circuit. The control circuit performs a combination calculation using the weights of the objects to be weighed held in a predetermined number of weighing hoppers located in the combination calculation area. As a result of the combination calculation, when a weighing hopper holding an object to be weighed included in the combination is located in the discharge area, the control circuit controls the weighing hopper to discharge the object to be weighed from that hopper. The control circuit outputs a command signal to the supply device so that the object to be weighed is supplied to the weighing hopper at the timing when the weighing hopper that has discharged the object to be weighed is located in the supply area.
