Patent ID: 8689525

Claim:
A machine (M) for filling and capping vials (F) comprising, arranged in a cascade fashion: a supply station ( 1 ) of empty vials (F); an Archimedes screw ( 2 ) 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 device (D) for disengaging a predetermined number of vials (F) from the screw ( 2 ), activated in phase relation with the screw ( 2 ), and for transferring the vials (F) transversally; a comb conveyor ( 3 ), step-moved and designed to receive the predetermined number of vials (F) from the device (D), consequently to a suitable phase relation between a velocity of the conveyor ( 3 ) and the activation of the device (D); a filling station ( 6 , 7 ), 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 capping station ( 10 , 11 ) for sealing a plurality of vials (F) which is equal to the predetermined number of vials (F); an outlet zone (U) for conveying the vials (F) out of the operating line of the machine; and, wherein the screw ( 2 ) exhibits peripheral grooves ( 20 ) which are equal in number to the predetermined number of vials (F) and parallel to one another, and in that the device (D) comprises pusher means (S) conformed such as to engage the grooves ( 20 ) and project towards the vials (F), transferring the vials (F) between the ribs of the comb conveyor ( 3 ).
