A combination weighing device facilitates the performance of operation using optimal operational settings. The combination weighing device includes a dispersion feeder, a plurality of radial feeders and a plurality of weighing hoppers. The dispersion feeder is disposed in an upper portion, and conveys and disperses supplied articles. The radial feeders are arranged radially on the periphery of the dispersion feeder, and convey the articles that are discharged from the dispersion feeder. The weighing hoppers receive the articles discharged from the radial feeders. The combination weighing device performs a combination weighing based on the weight of the articles in the weighing hoppers. In the combination weighing device, the operational settings are performed automatically.

A form-fill-seal machine is capable of reducing poor sealing caused by a packaged article catching in lateral seal portions. The form-fill-seal machine is provided with an upper tube, a lower tube disposed therebelow, a former, a lateral sealing mechanism below the lower tube, and opening and closing sliding members. A packaged article is dropped through the interiors of the upper tube and the lower tube. The former winds a sheet of a film F around the circumference of the lower tube to convert same into a tubular film. The lateral sealing mechanism laterally seals the tubular film. The opening and closing sliding members, which are disposed between the upper tube and the lower tube, shut off an upwardly oriented flow of gas from the interior of the lower tube when in a closed state.

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.
