  • Patent number: 11248948
    Abstract: When a combination calculator has selected both a first weighing hopper and a second weighing hopper corresponding to one feeding hopper, a controller drives a feeder so as to increase an amount of objects to be weighed that are held in the one feeding hopper, and then causes the one feeding hopper to discharge the objects to be weighed in both a first direction and a second direction concurrently to distribute the objects to be weighed to the first weighing hopper and the second weighing hopper that have been emptied.

  • Patent number: 11137280
    Abstract: A weighing apparatus includes a rough-charge weigher and a combination weigher. The rough-charge weigher includes: a feeding device; a lower hopper configured to hold and discharge objects to be weighed that are fed from the feeding device; a feeding adjuster configured to feed the objects to be weighed from the feeding device to the lower hopper, and adjust an amount of the objects to be weighed that are fed to the lower hopper; and a weight sensor provided on either the feeding device or the lower hopper. A controller: continuously measures, by the weight sensor, a weight of the objects to be weighed that are fed by the feeding adjuster from the feeding device to the lower hopper; and at a point when the weight of the objects to be weighed that are fed to the lower hopper has reached the rough-charge weight, stops the feeding adjuster.
