A bag-making and packaging machine works with a weighing machine installed upstream to manufacture bags containing article discharged from the weighing machine. The bag-making and packaging machine includes a forming unit, a transverse sealing unit, a conveyance unit, a communication unit, and a control unit. The communication unit receives from the weighing machine a signal relating to weighing and discharge of the article. The control unit has a disposal mode for disposing of the article in the weighing machine. When changing from a normal production mode to the disposal mode, the control unit performs control to skip, among operations in the normal production mode, the operation of the transverse sealing unit implemented in conjunction with the signal received by the communication unit from the weighing machine.

A system and method for dispensing a powdered pharmaceutical into a bottle is disclosed. The system includes a filler having a powder filler head and respective weight sensor, two or more draft shields, and one or more static reduction devices. In some embodiments, the system also includes one or more dust extractors. In some embodiments, the static reduction device is an active static reduction device, such as one or more static bars. The two or more draft shields may include an inner draft shield to reduce small pressure and/or airflow changes and an outer draft to reduce large pressure and/or airflow changes.

Accurate and repeatable portioning of polycrystalline silicon chunks without excessive generation of fines is accomplished by separating silicon chunks into a multiplicity of weighed portions and combining at least four portions which together closely match a target weight into a plastic shipment bag which is then closed.

A weighing and packaging apparatus (10) includes a packaging unit (14), a weighing unit (11), and a frame (70). The packaging unit (14) includes a film transport mechanism (30) that transports a film (F) in a film transport direction, a detachable former (22), a former seat (82) that supports the former (22), and a sealing mechanism (50). The weighing unit (11) is positioned on an upper side in a vertical direction of the packaging unit (14), and supplies articles (A) to be packaged to the packaging unit (14). The frame (70) supports at least the weighing unit (11), and includes legs including a first front leg (71a), a first back leg (71b), a second front leg (72a), and a second back leg (72b). A movable portion (89) including the former seat (82) moves in a maintenance mechanism movable space (PM) when the former (22) is detached. All of the legs are located so as to avoid a leg prohibited space (PP).
