SED-4-2FGS-3 — High-Speed 4-Head Screw-Type Powder Filling and Stoppering Machine

Vials feed via 304 SS turntable into the linear infeed track and reach the rotary positioning station, where a Mitsubishi servo-driven star-wheel locks each vial in place (servo-current sensing detects jams and prevents bottle breakage). The 316L stainless steel powder hopper holds the API powder; a low-speed permanent-magnet motor drives the powder-feed screw to maintain head pressure at the dosing screws. Each of 4 servo-driven dosing screws (Mitsubishi 400W) rotates a programmable count to deliver the set fill weight (0.1–5.0 g). Optional secondary or tertiary fill cycles per bottle for tricky powders. After fill, vials transit on the conveyor to the vacuum-free rotary stopper-pressing system: a chopstick-style mechanism delivers each rubber stopper into a spring-loaded cap-pressing disc with a rising cam — vials rotate vertically as they rise, no vacuum needed. No-stopper detection by Leuze sensor triggers auto-rejection. Production statistics counted by Panasonic photoeye; Siemens 12" HMI provides 3-level password lockout, jog/auto modes, recipe storage, fault history.
