Abstract:
A method for filling a container (2) with a filling product, comprising the steps of: positioning the container (2) in a filling station (1) so that its mouth (2b) is below the filling valve (9); separating a treatment volume (40) of the neck (2a) comprised between the filling valve (9) and at least one part of the neck (2a) of the container (2) from an external environment (6) containing the body (2d) of the container (2); dispensing plasma into the treatment volume (40) so that it flows over the neck (2a) of the container (2); enabling the filling valve (9) to dispense the filling product into the container (2).
Abstract:
A fastening device for fastening a changeable attachment with a container handling station includes a first member and a second member formed as a fitting counterpart to said first member. The attachment can be transferred into the fastened position by uniting and rotating said members relative to each other. A fixed stop disposed on the fastening device in the fastened position prevents rotating the two members relative to each other in one rotational direction, and an elastic, radially snapable section acts as a stop without application of any external force and prevents the members from rotating relative to each other in the other rotational direction. The snapable section fastens the two members relative to each other and can be pressed in radially such that it no longer acts as a stop and the attachment can be rotated from the fastened position and removed from the container handling station.
Abstract:
A capping device fits caps onto containers by applying an axial force to the caps as they are threaded onto the containers. The capping device utilizes a spindle rotatable about an operational axis for imparting rotation to a capper unit. A connector coupled to the capper unit is releasably coupled to the spindle by a quick release mechanism. The quick release mechanism is normally biased in the locked position and is configured to automatically move from the unlocked position back to the locked position when the connector mates with the spindle as a user re-connects the capping unit back to the spindle. Methods of releasing and re-connecting the capping unit to the spindle are also disclosed.
Abstract:
A capping device fits caps onto containers by applying an axial force to the caps as they are threaded onto the containers. The capping device utilizes a drive member rotatable about an operational axis for imparting rotation to a capper body slidably coupled to the drive member. A helical spring urges the capper body away from the drive member with a biasing force. An adjustment mechanism adjusts the biasing force thereby adjusting the axial force applied to the caps as they are threaded onto the containers. A pair of retaining pins move between a latched position to prevent adjustment of the biasing force and an unlatched position to allow adjustment of the biasing force. The retaining pins are biased in the latched position to prevent inadvertent adjustment of the biasing force during use.
Abstract:
This invention relates to an apparatus for rotating cylindrical downwardly facing threaded caps onto upwardly facing, threaded open ends of containers primarily for use in container capping machines. The apparatus comprises at least one spindle assembly slideably carried by a support frame for movement generally parallel to the vertical axis of the spindle assembly, the weight of the spindle assembly causing the downward movement of the spindle assembly, structure carried by the support frame for controlling the vertical movement of the spindle assembly, and a selectively adjustable device for resiliently urging the spindle assembly upwardly so that the device at least partially supports the weight of the spindle assembly and the container is engaged by a cap with less than the full weight of the spindle assembly pressing downwardly on the container.
Abstract:
A laboratory capper, decapper or combination capper/decapper includes a deck containing with a nest designed to hold an SBS-formatted tube storage rack, and a bit exchange magazine assembly containing one or more sets of adapter bits. The adapter bits are mounted on and unloaded from motor driven fittings, and are exchanged in order to cap or decap laboratory sample tubes or vials that have different head configurations. The bit exchange magazine assembly enables the bit to be exchanged robotically.
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 chuck for a bottle capping machine is capable of applying a pre-defined torque to a cap and reducing top load during application. The capping chuck includes a drive gear mechanically connected to a clutch. The clutch controls the torque transmitted to a gripper head through a driveshaft. The gripper head secures the cap to the bottle, and includes a substantially continuous perimeter wall surrounding a plunger that moves under load in a direction parallel to the longitudinal axis of the driveshaft. The extent of movement can be controlled by a resistance element such as, for example, a spring. An engagement device affects the contact the drive gear has with the bull gear of the capping mechanism. The engagement device can rotate the capping chuck relative to the bull gear to ensure positive engagement of the drive gear with the bull gear. The engagement device can include a slotted opening and an adjustment screw.
Abstract:
A capping device fits caps onto containers by applying an axial force to the caps as they are threaded onto the containers. The capping device utilizes a drive member rotatable about an operational axis for imparting rotation to a capper body slidably coupled to the drive member. A helical spring urges the capper body away from the drive member with a biasing force. A bearing mechanism allows relative free sliding movement of the capper body relative to the drive member. The bearing mechanism includes a plurality of bearing members. In one embodiment, the bearing members are bushings. In another embodiment, the bearing members are ball bearings.
