A measuring device includes a first measuring hopper, a first supply portion arranged above the first measuring hopper to supply the objects to the first measuring hopper, a second measuring hopper, a second supply portion fixedly arranged above the second measuring hopper to supply the objects to the second measuring hopper, a plurality of accommodating hoppers circumferentially arranged below the first and second measuring hoppers, and a control portion configured to control the second supply portion and the plurality of accommodating hoppers such that an accommodating hopper discharges the objects only if the total weight of the objects in the accommodating hopper that are discharged from the first and second measuring hoppers is substantially and no smaller than the predetermined weight. The plurality of accommodating hoppers are intermittently circulated such that each of the accommodating hoppers successively receives the objects from the first and second measuring hoppers.

A boxing device includes a collecting unit, a group weight measuring unit, a determination unit, and a boxing unit, and adapted to pack a predetermined weight or a predetermined number of articles in a box. The collecting unit is configured and arranged to collect the articles as a group. The group weight measuring unit is configured and arranged to measure the weight of the group. The determination unit is configured and arranged to determine whether or not it is adequate to pack the group of the articles in the box based on the weight measured by the group weight measuring unit. The boxing unit is configured and arranged to pack, in the box, a plurality of the groups of the articles determined by the determination unit to be adequate to be packed in the box.

A method and apparatus of forming portions of tobacco, and of removing the same by an conveyor having at least one path of holders for a respective portion, in which the holders are filled with individual portions of the contents at least two filling lines of one or more filling stations, and, prior to the individual filling operations, individual portions of the contents are weighed and weighed portions that satisfy the predetermined conditions—acceptable portions—are filled cyclically into the holders and weighed portions that do not satisfy the predetermined conditions are detected and ejected as defective portions, characterized by components and steps of (a) following detection of a defective portion, that holder which the filling line originally predetermined for filling this holder would have filled with the contents portion, on which the defective portion is based, had the contents portion satisfied the predetermined conditions—defective-portion holder—is sensed, and a filling line other than that originally predetermined for filling the defective-portion holder—compensating filling line—fills the defective-portion holder, preferably outside the original filling cycle thereof, with an acceptable portion that satisfies the predetermined conditions.

The invention provides a boxing apparatus (100) for boxing bags of predetermined weight or a predetermined number of bags comprises a collecting section (5), a group weight checker (6), a control section (10), and a boxing / sealing section (7). The collecting section (5) collects bags and makes a group of bags. The group weight checker (6) weighs the group of bags. The control section (10) judges appropriateness to box the group of articles on the basis of the weight value measured by the group weight checker (6). The boxing / sealing section (7) boxes groups of bags each of which is judged appropriate to be boxed by the control section (10). With this, a failure that there is a missing article is detected before boxing and an appropriate measure can be taken. As the result, the boxing apparatus operates less wastefully than conventional boxing apparatuses which judge appropriateness of the weight of bags (the number of those) after completion of the boxing and reject the whole box whose inappropriateness is found out from its production line.
