Patent ID: 8601777

Claim:
A machine (M) for packing vials (F), wherein it comprises, arranged in a cascade fashion: a supply station ( 1 ) of empty vials (F); an Archimedes screw ( 3 ) having a rotation axis parallel to a longitudinal development of the machine (M), supplied with the vials (F) in arrival from the supply station ( 1 ), and destined to transfer the vials (F) to an outlet thereof, at a predetermined step; a first device ( 4 ) comprising at least two cogged sectors, with an equal step to the step of the screw ( 3 ), which at least two cogged sectors rotate on a same axis independently of one another, and are alternatively activated in phase relation with the screw ( 3 ), in order to receive a predetermined number of vials (F) from the screw ( 3 ); a comb conveyor ( 5 ), step-moved and designed to receive the vials (F) from one or another of the cogged sectors of the first device ( 4 ), consequently to a suitable phase relation between a velocity of the conveyor ( 5 ) and a peripheral velocity of the corresponding cogged sector; a filling station ( 8 ), designed for introduction of a liquid solution contemporaneously into a plurality of vials (F), which plurality is equal in number to the predetermined number of vials (F); a statistical weighing station ( 10 ) of the vials (F), arranged in proximity of the filling station ( 8 ), able to detect a tare and a gross weight of sample vials (F) of the vials (F); a capping station ( 11 ), for at least partly sealing a plurality of vials (F) which plurality is equal to the predetermined number of vials (F); a second sector device ( 12 ), conformed like the first device ( 4 ), in which at least two cogged sectors are alternatively activated in phase relation with the movement of the comb conveyor ( 5 ); a star device ( 13 ), activated in phase relation with the movement of the cogged sector of the second device ( 12 ), which star device ( 13 ) is interested by the predetermined number of vials, and exhibits a double outlet, a first outlet (U 1 ) and a second outlet (U 2 ); the star device ( 13 ) being destined to direct conforming vials (F 1 ) towards the first outlet (U 1 ), and to reject vials (F 2 ) which do not conform to determined requisites and to convey them towards the second outlet (U 2 ).
