Abstract
A dispensing device for a powder filling machine comprises a duct with at least one dispensing outlet from which a powder material is directed into a container positioned beneath. The outlet incorporates an iris diaphragm with a plurality of occluding elements capable of movement between an operating condition in which the outlet is closed, disallowing passage of the powder material, and a non-operating condition in which the outlet is open, with the occluding elements compassing a flow section aligned concentrically with the duct and allowing the passage of the powder material.
Claims21
A dispensing device in machines for filling containers with powder material, comprising:
- a feed duct referable to a longitudinal axis and furnished with at least one outlet from which powder material is dispensed into a corresponding container;
- and
- closure means associated with the outlet, capable of movement between an operating condition in which the outlet is closed to disallow the passage of the powder material and a non-operating condition in which the outlet remains open,
- wherein the closure means comprises a plurality of occluding elements each capable of movement between a first position corresponding to the operating condition of the closure means and at least a second position corresponding to the non-operating condition of the closure means, each occluding element obscuring a part of the dispensing outlet when in the first position and combining with the remaining elements when in the second position to establish a flow section affording a passage to the powder material, each occluding element being directly and mechanically connected with at least one other adjacent occluding element.
