A combination weighing device (1) includes: a plurality of hoppers (5, 6) configured to temporarily retain the articles which are conveyed by the conveyance unit, and then discharge the articles downstream; an acquisition unit (50) configured to acquire weight values of the articles retained in each of the hoppers; and a control unit (30) configured to specify at least one of the hoppers from which the articles are discharged on the basis of the weight values and a target range which is preset. The combination weighing device (1) operates such that the articles are additionally supplied to a selected hopper while the articles retained in the hopper are left as is in the first mode, and operates such that, instead of the articles being additionally supplied to a selected hopper, the articles retained in the selected hopper are discharged to the outside, and the articles are newly supplied to the selected hopper in the second mode.

A combination weighing apparatus (1) includes: a first channel (CH1) for processing of articles; and a second channel (CH2) for processing of articles. The combination weighing apparatus (1) includes a discharge chute (60) and a timing hopper (70). The discharge chute (60) has: a slide face (65) sloping toward a center in a horizontal direction (X) of the combination weighing apparatus (1) as downward in a vertical direction (Z); and a chute outlet (66) through which the articles are discharged. A distance in the horizontal direction (X) between a center of the outlet (72a) in the first channel (CH1) and a center of the outlet (72a) in the second channel (CH2) is longer than a distance in the horizontal direction (X) between a center of the chute outlet (66) in the first channel (CH1) and a center of the chute outlet (66) in the second channel (CH2).

A weighing apparatus includes: a conveyance unit configured to convey an article; a weighing unit configured to weigh the article on the conveyance unit; and a processing unit including a plurality of digital filters set in advance and configured to process an original signal that is output from the weighing unit. The processing unit is configured to select one digital filter among the plurality of digital filters, based on a result of applying each of the plurality of digital filters to the original signal, when the conveyance unit is in operation and the article is not conveyed by the conveyance unit.

The object of the present invention is to provide a novel conveying device with which it is possible to easily adjust a conveying amount of articles in a trough using a restricting plate, and a combination weighing apparatus having the conveying device. A conveying device (1) to convey articles in a trough (2) has a restricting plate (4) to restrict a flow of the articles in the trough and the angle at which the restricting plate faces the articles is variable. With this configuration, there is no need to prepare a plurality of restricting plates that have different shapes and materials or to exchange such a plurality of restricting plates in the same manner as in a conventional device because the conveying amount in the trough can be adjusted merely by varying the angle at which the restricting plate faces the articles.
