摘要： A weighing apparatus comprises feeder means for temporarily storing an object to be weighed and discharging the object to be weighed as needed, a plurality of weighing hopper means each having a plurality of storage chambers which are integrally coupled, a plurality of weighing means, provided in correspondence with the plurality of weighing hopper means, for independently weighing weights (referred to as partial weights hereinafter) of objects to be weighed, stored in the storage chambers, and a control apparatus for calculating partial weight values of the objects to be weighed based on weighing signals from the weighing means. The control apparatus combines at least one of the calculated partial weight values and the number of objects to be weighed, calculated from the partial weight values, so as to select a combination closest or equal to at least one of a preset weight or a preset number, causes the selected objects to be weighed to be discharged and collected from the storage chambers, and includes at least a plurality of operation means for calculating at least one of true partial weights and the number of plurality of stored objects to be weighed. The control apparatus is controlled such that the discharge operation of the object to be weighed has a higher priority than that of the weighing operation of the object.

摘要： This invention provides a combined metering apparatus in which the convey efficiency of a target metering object from an upper-stage hopper to a lower-stage hopper is improved. For this purpose, the direction in which a bottom plate 33 of a pool hopper 25 is moved to open the lower open surface of a cylindrical body 26 and the direction in which a bottom plate 43 of a lower-stage metering hopper 35 is moved to close the lower open surface of a cylindrical body 36 are set the same. Also, the direction in which the bottom plate 43 of the metering hopper 35 is moved to open the lower open surface of the cylindrical body 36 and the direction in which a bottom plate 59 of a lower-stage timing hopper 50 is moved to open the lower open surface of a cylindrical body 51 are set the same. Hence, when the bottom plate of the lower-stage hopper is moved in the closing direction, the bottom plate of the upper-stage hopper is moved in the opening direction almost simultaneously, so that the target metering object in the upper-stage hopper can be transferred to the lower-stage hopper efficiently.

摘要： A novel electromagnetic balance-type weighing apparatus according to the invention includes a weighing pan/balance beam assembly (15) whose balance beam is angularly displaced as a function of the weight of an object of weighing placed on the weighing pan. An electromagnetic coil (9) is provided to generate an electromagnetic force that offsets the displacement of the balance beam of the weighing pan/balance beam assembly (15) caused by the weight of the object of weighing. A displacement detector (3, 4, 5) is provided to detect the displacement of the balance beam of the weighing pan/balance beam assembly (15). An operation unit (7) performs operations to determine a control voltage in response to the detection signal transmitted from the displacement detector (3, 4, 5). A current transducer circuit (20) generates an electric current in response to the control voltage applied to it by the operation unit (7) and supplies it to the electromagnetic coil (9). The current transducer circuit (20) comprises a negative feedback loop circuit for feeding the output current from said current transducer circuit (20) back to the input terminal of the current transducer circuit (20). A weight calculator (24) calculates the weight of the object of weighing from the output current of the current transducer circuit (20).
