Abstract: The components of a rotary conveyor (1) for a carousel type capping machine (2) include a center shaft aligned on a main axis (X) coinciding with the main axis of the machine (2), a carrier element (4) coupled to the shaft so that the two rotate as one about the main axis (X), and a set of gripper mechanisms (5) associated operationally with the carrier element (4), distributed circumferentially about the supporting shaft. Each gripper mechanism (5) is switchable between a first configuration, establishing a recess (6) in which to accommodate a respective container (3), a second configuration in which the container (3) is retained within the recess (6) by a predetermined gripping force, and a third configuration in which the container (3) is restrained by a gripping force greater than the force exerted in the second configuration, so as to counteract any unwanted rotation of the container (3) about its longitudinal axis (Y) that might be induced during the course of capping operations.

Abstract: Containers are closed with screw caps by a carousel machine of which a central drum (31) is rotatable about a vertical axis (A) and carries a set of capping units (36) equipped with respective capping heads (37), each presenting a gripper (38) by which the cap (3) is held, and a mechanism (66) by which the hinged jaws (39) of the gripper (38) are opened and closed; each capping head (37) is capable of axial motion induced by components incorporated into the relative unit (36), which are guided axially in their movements and supported by auxiliary components (40; 49, 50) associated rigidly with the central drum (31).

Abstract: Capping assemblies (2) of the type fitted to capping units (1a) in a machine for packaging containers filled with fluid or powdered products are equipped with a gripping apparatus (1) comprising a gripper (4) with three arms (5), each carrying an adapter (20) furnished with a pad (20b) offered in direct contact to the cap, through which the gripping action is applied. Each adapter (20) is secured to a fitting (17, 18) insertable into a socket (16) afforded by the bottom of a structural member (6) that forms the main part of each arm (5) and is hinged to the movable head of a relative capping assembly (2); when inserted into the structural member (6), the fitting (17, 18) is retained automatically by a snap lock mechanism (12) incorporated into the arm (5), which can be released subsequently by introducing the tip of a screwdriver into a slot (18a) created in the side of the fitting (17, 18) and levering the components apart.

Abstract: A capping machine (1) of carousel design comprises a centre shaft (2) turning on a fixed base frame (3) about a vertical axis of rotation (Y), a set of capping units (4) encircling and revolving as one with the shaft (2) about the axis of rotation (Y), and a cylindrical cam (5) interposed between the shaft (2) and the capping units (4), by which the single units (4) are caused to move toward and away from the fixed base frame (3). During operation, the cam (5) is held in at least one predetermined fixed position relative to the base frame (3) by a single supporting element (6) anchored to the base frame (3), concealed internally of the rotating shaft (2) and connected to the cam (5), which represents a departure from the conventional method of supporting the cam on two or more columns located externally of the carousel structure and exposed to view.

The hollow body (12) is equipped with a pedestal (19) presenting a platform (20) on which to stand the container, and a connecting element (21) of which a first end (21a) is coupled with the load cell internally of the hollow body (12) and a second end (21b), opposite to the first end (21a), is secured to the platform (20). To advantage, the first end (21a) of the connecting element (21) is seated in a through opening (13) afforded by the underside of the hollow body (12).

Abstract: Containers for packaging liquid or powder products are directed onto a carousel (1) presenting a support element (9) equipped with a number of peripheral stations (10), each accommodating a relative container (2), and set in rotation about a vertical axis (X) by a drive system (6) housed internally of floor-standing frame (5) on which the carousel (1) is mounted. The support element (9) presents substantially disc-like appearance and is hollow, composed of a top panel (11) and a bottom panel (12) distanced one from another in such a way as to create an annular chamber (13) between the two panels.

Abstract: A packaging machine or machine unit, as used in particular for capping containers (5), is enclosed by a structure (1) that comprises a casing (2) positioned at least in part around the active components (3) of a packaging unit (4) supplied with open containers (5). The casing (2) comprises a fixed cowl (13) encompassing the components (3) of the packaging unit (4), and a movable cowl (23) furnished with at least one sealing element (4). The movable cowl (23) is capable of movement between an open configuration, in which a gap (23a) is created between the fixed cowl (13) and the movable cowl (23) so as to place the fixed cowl (13) in fluid communication with the surrounding atmosphere, and a closed configuration in which the sealing element (24) of the movable cowl (23) engages the fixed cowl (13), occluding the gap (23a) and consequently isolating the interior of the fixed cowl (13) from the surrounding atmosphere.
