Title: A COMBINATION WEIGHER
Abstract:
This invention relates to a combination weigher(100) including a dispersion unit(101) adapted to radially disperse product material dropped in from above onto the dispersion unit, plurality of weighing hoppers(108), plurality of conveyor units (103) arranged around and below a periphery of the dispersion unit(101). The conveyor units include troughs having infeed ends positioned below the dispersion unit (101) and outfeed ends positioned above the weighing hoppers(108), and spiral shaped members(104)extending from the infeed ends towards the outfeed ends. The spiral shaped members being operable connected to an operation unit for operating a rotational movement of the spiral shaped members and thus the conveying of the product material from the infeed ends towards the outfeed ends and into the weighing hoppers(108). The combination weigher further includes conical shaped members (105)that are arranged within the spiral shaped members (104) with the wider ends positioned adjacent to the infeed ends of the troughs and the narrower end extending towards the outfeed ends of the troughs.
