Combination Weigher
First Claim
1. A combination weigher comprising:
- a plurality of combination hopper groups each including a plurality of combination hoppers which are fed with objects to be weighed;
a plurality of upper collecting chutes which are disposed below the combination hopper groups to respectively correspond to the combination hopper groups and are configured to gather the objects to be weighed which have been discharged from the combination hoppers and to discharge the objects to be weighed from discharge outlets at bottom parts thereof;
a plurality of upper collecting hoppers which are provided at the discharge outlets of the upper collecting chutes to respectively correspond to the upper collecting chutesand are configured to hold the objects to be weighed which have been discharged from the discharge outlets of the upper collecting chutes and then to discharge the objects to be weighed; and
a control means configured to repeatedly perform a combination process in which combination calculation is performed based on weights of the objects to be weighed which are held in the combination hoppers belonging to the plurality of combination hopper groups to determine a combination of the combination hoppers holding the objects to be weighed whose total weight falls within a predetermined weight range and determine the combination as a discharge combination, a first discharge process in which the combination hoppers belonging to the discharge combination determined in the combination process discharge the objects to be weighed, and a second discharge process in which the plurality of upper collecting hoppers discharge the objects to be weighed simultaneously, to discharge the objects to be weighed which have been discharged from the combination hoppers and are held in the upper collecting hoppers.

Abstract
A combination weigher includes a plurality of upper collecting chutes disposed below weighing hoppers, a plurality of upper collecting hoppers provided at discharge outlets of the upper collecting chutes, a lower collecting chute provided below the upper collecting hoppers, a lower collecting hopper provided at a discharge outlet of the lower collecting chute, and a control unit which repeatedly performs a combination process to determine one discharge combination of the weighing hoppers, a discharge process for discharging the objects from the weighing hoppers onto the upper collecting chutes, and a discharge process for discharging the objects simultaneously from the upper collecting hoppers, and a discharge process for discharging the objects from the lower collecting hopper.
