Abstract: The machine includes groups of bushes (1) of dimensions suitable for the superposed and aligned containment of a base cover (14), of a tablet (52) and of a lid cover (14).

Abstract: The bases and caps are aligned in two stages, with displacement by first pointed pushers (13-31) into corresponding calibrated horizontal channels (12-29) followed by displacement by second pushers (21-44) into corresponding calibrated vertical and descending channels (312-329). The second pusher (21) pushes the bases horizontally into the wider terminal part (20) of the descending channel, where the base is sucked by its sealed end and inserted into the corresponding supporting socket (1), with a vertical disposition and with the opening upwards. The second pusher (44), operating with the caps, acts on the intermediate parts of these with a point (144) which causes the caps to rotate with the opening downwards and transfers them with a vertical disposition into the wider terminal part (42) of the descending channel where the cap is held by a suction tube (46) which inserts it into the corresponding supporting socket (2).

Abstract: A movable abutment plate (28) which is bound by common vertical guide to a vertical axis, an axially hollow turntable (9) carrying two sets of vertical dosing devices (V1V2) and a central cap-shaped screw (29) secured to the top end of bar (33) are provided. Bar (33) passes through the turntable (9) and turret (1), such that the bar extends into the lower part of the dosing machine, where the bar (33) includes a crown gear (36) with suitably shaped peripheral apertures (37) arranged in an equispaced relation. When turntable (9) is lowered, one of the apertures (37) in crown gear (36) engages with a crankpin (41) which is fitted on the slowly rotating shaft of geared motor (43) controlled by encoder (44). When the volume of dosing devices (V1, V2) needs adjustment, turntable (9) is temporarily lowered and geared motor (43) is actuated to thereby lift or lower plate (28), against which bear the lateral appendices (25) of the moving elements of the dosing devices (V1, V2).
