As cases of COVID-19 began to intensify across the U.S., a diagnostics manufacturer reached out to ESS Technologies to build two identical filling systems with automated cap torque for diagnostics vials to be used in manufacturing COVID-19 test kits. Speed and urgency drove the project. The system needed to be fast, capable of filling up to 120 vials/min.
Though originally developed for vials used in COVID testing, the machines can be used for applications using vials or small bottles. Available in semi-automatic and fully automated configurations, ESS’ flexible filler/capper uses a circular puck conveyor system to transport vials or small bottles to the inline filling system. A timing screw drive positions six vials beneath the six-up diving nozzle assembly where a precise amount of diagnostic reagent is dispensed. The cap placement is automated using Fanuc SCARA robots and a cap feeder. A three-up final torque station then applies the precise amount of torque to the caps. The machine uses Allen Bradley PLC controls and a 6 in. color touchscreen HMI for ease of operation. An optional 10 in. HMI is available. The system provides fast changeover, under 10 min.
