Abstract: A combination weighing device includes: a storage unit that stores time-series measurement values sequentially acquired by the measurement hoppers; a time measurement unit that measures an elapsed time from a timing corresponding to supply of the products to the measurement hoppers until a timing at which the time-series measurement values enter a region considered to be stabilized when the time-series measurement values stored in the storage unit converge to the region considered to be stabilized as a stabilization time until the measurement values become stabilized; and a selection unit that acquires the stabilization times by the time measurement unit over a plurality of cycles and can select a recommended stabilization time that is the stabilization time in which a predetermined measurement accuracy can be maintained based on a standard deviation of the acquired stabilization times for the plurality of cycles.

Abstract: A combination weighing device includes: an electroconductive plate opposed, with an interval, to an electroconductive part enabling detection of water intrusion inside the combination weighing device; a voltage wire for application of voltage to the electroconductive plate; and a detector that detects a potential difference between the electroconductive part and the electroconductive plate, wherein the detector or a controller of the combination weighing device determines presence or absence of water intrusion inside the interval, based on the detected potential difference.

Abstract: 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 to convey articles in a trough has a restricting plate 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.
