Custom Versatile Monoblock Can Also Apply Difficult Nasal Spray Cap

Greensboro, NC — Chase-Logeman Corporation introduces its latest automatic liquid filling and capping system with 100% check weighing designed for applications in pharmaceutical, biological, and diagnostic filling. It is ideal for R&D, pilot plant, and low speed production up to 35 vials per minute. Rates to 60 bottles per minute or better are possible without check weighing.

The Model FCC3-12H three function Monoblock features a unique two star wheel design that gives you the flexibility to isolate specific functions as needed. Filling and check weighing occur on the first star wheel with a non-destructive sample check weighing with direct feed-back control to the filling pump (either peristaltic or servo piston) that adjusts fill volumes automatically. The sample check weighing takes place in the star wheel utilizing two check weighing stations, a tare weight and a gross weight station. The tare weight is taken at the first station and data transferred to a microprocessor. After filling, the gross weigh station reweighs the vial to determine the gross weight. The microprocessor computes the difference between the tare weight and gross weight to determine the product weight (net weight). Each check weigh is compared to the target fill volume, the differencial value is then used to make trim adjustments to the fill volume, based on short term running average, i.e. weigh 10 shots, feed back to filler.

The trimming of the process allows improved accuracy without operator intervention or attention. Screw capping or stoppering occurs on the second star wheel. The machine illustrated includes a sanitary conveyor, a multi unit laminar flow enclosure, and both peristaltic and piston filling. Other options are available including ChaseLock® no tool, quick-change bottle and closure change parts.
