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.

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 combination weighing device includes a calculation part, a normal discharge part, a sample selection part, and a sample discharge part. The calculation part selects a plurality of types of articles according to a predetermined ratio and the weights thereof. The sample selection part selects specific types of articles from amongst the plurality of types of articles selected by the calculation part. The sample discharge part discharges the specific types of articles selected by the sample selection part.

The combination weighing apparatus is an apparatus that conducts combination weighing of articles based upon weight data from a plurality of weight hoppers, and is comprised of a plurality of supply buckets that supply articles to any of a plurality of weighing hoppers, a rotation mechanism that rotates the supply buckets so that they move along an arrangement of the weighing hoppers in a weighing area, and a control computer. The control computer controls the supply of articles from the supply buckets inside the weighing area to the weighing buckets, and from amongst the plurality of weighing hoppers that request a supply of articles, priority is given to the weighing buckets that are downstream in the direction of rotation, and article supply takes place. In a combination weighing apparatus that supplies articles from supply buckets that rotates with respect to weighing hoppers, preventing difficult situations such as articles being supplied to predetermined weighing hoppers, and improving the accuracy of combination weighing.
