A hopper is provided with which damages of articles can be suppressed without lowering the processing speed. A hopper () includes a first hopper main body (), and a first gate (G). A first inner surface () of the first gate (G) forms a collecting space (A) for holding articles with the first hopper main body (), and stores articles in the interior of the collecting space (A) when in the closed state and discharges articles by turning to open. The first inner surface () includes a first upper slanted surface (S) and a first lower slanted surface (S) that are continuous. An angle formed by the first lower slanted surface (S) and the horizontal plane is smaller than an angle formed by the first upper slanted surface (S) and the horizontal plane.

A measuring device is arranged to store a block or group of a plurality of objects in a state where the objects are congested in the block, to suppress the scattering magnification of the objects when the objects are dropped off to prevent failures such as seal bite in a filling device disposed below the measuring device, to shorten the dropping length of the objects, and to reduce the contact resistance of the objects to a receiving opening of the filling device during the objects are dropped off to attain the discharging speed of the objects. The shapes and opening degrees of a gate unit can be changed so that a lower opening of a hopper is disposed inside the receiving opening of the filling device in a top plan view.

A storage hopper temporarily stores articles supplied from above and then discharges the articles downward. The storage hopper includes a holding member of an article holding change mechanism in a storage portion. The holding member changes a state in which the articles are held in the storage portion according to a state of the articles.

A first gate opens obliquely downward, and maintains the posture, rendering the slope angle of the bottom surface thereof steeper than that of the bottom surface of the second gate. Thus, the bottom surface of the second gate forms a gentle slope sliding surface, and the bottom surface of the first gate forms a steep slope sliding surface. Then articles drop following the shape of a parabola toward the bottom surface of the first gate on the steep slope side, with momentum gained from sliding down the bottom surface of the second gate on the gentle slope side, and then change the sliding trajectory inward upon bumping into the bottom surface of the first gate. The articles then drop following the shape of a parabola toward the center area of a dispersal table, with momentum gained from sliding down the bottom surface of the first gate.

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.
