Zusammenfassung:To improve supplying properties of bulk objects.SOLUTION: A measuring machine comprises: a measuring hopper 31 that includes a weight sensor 3S attached thereto, for measuring a weight of fed bulk objects, and alternately performs a first measuring mode of not discharging the bulk objects until a detected weight, the weight measured by the weight sensor 3S, reaches a prescribed amount, and a second measuring mode of discharging the bulk objects when the detected weight reaches the prescribed amount; and a supply unit 2 that sequentially supplies bulk objects to the measuring hopper 31. The supply unit 2 includes a movable section 2M that rakingly delivers the bulk objects by pins 2P foresting, with their projecting to an outer peripheral surface of a rotating roller 2R along the radial direction, and a stationary section 2F extending along a part of a trajectory formed by the tips of the pins 2P when the roller 2R rotates, and having a guide face 2G for guiding raking delivery of the bulk objects by the pins 2P.SELECTED DRAWING: Figure 4 【課題】バラ物の投入性を高める。【解決手段】計量機は、投入されたバラ物の重量を計測する重量センサ3Sが付設され、重量センサ3Sで計測された重量である検出重量が所定量に達するまではバラ物を排出しない第一計量モードと検出重量が所定量に達するとバラ物を排出する第二計量モードとを交互に実施する計量ホッパ31と、計量ホッパ31へバラ物を順次投入する投入ユニット2と、を備える。投入ユニット2は、回転するローラ2Rの外周面に対して径方向に沿って突出した状態に林立されたピン2Pでバラ物を掻き送る可動部2Mと、ローラ2Rが回転するときにピン2Pの先端のなす軌跡の一部に沿って延在するとともにピン2Pによるバラ物の掻き送りを案内するガイド面2Gを有する固定部2Fと、を有する。【選択図】図4
