A weighing system comprising;
- a platform scale on which a container containing objects is placed;
- and
- a hand-operated combination weigher including a plurality of weighing trays on which the objects are put;
- wherein a controller of the weighing system derives a target weight of the objects in the combination weigher using a weight of the container which is weighed by the platform scale;
- and
- the controller selects a combination of the weighing trays so that a combination weight of the objects on the weighing trays falls within an allowable range of the target weight.
A weighing work method comprising:
- a step of stacking containers in plural layers on a platform scale of subtraction type, each of the containers containing the objects of predetermined number;
- a step of putting the objects of predetermined number on each of a plurality of weighing trays in a hand-operated combination weigher;
- a step of obtaining a weight of one container when one of the containers is taken out of the platform scale;
- a step of deriving a target weight of the objects in the combination weigher using the weight of the container;
- a step of selecting a combination of the weighing trays so that a combination weight of the objects on the weighing trays falls within an allowable range of the target weight;
- and
