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:
An apparatus is provided for non-destructively testing for a predetermined minimum release torque of container caps on containers at a torque testing station. The apparatus includes a device for clamping the containers at the torque testing station; a device for grasping the caps of the containers at the torque testing station; a device connected to the cap grasping device for applying a release torque to the container caps; and, a device including a strain gage coupled to the release torque applying device for sensing the level of release torque applied to the caps and providing a signal indicative of such level. The apparatus also includes selectively operable controls for destructively testing selected capped containers, on a sampling basis, to determine the actual release torque of the container caps on such containers.
Abstract:
A transgrip spindle assembly includes a ball head coupler. A transgrip arm includes a quick change bore, and a lateral bore opening orthogonally into the quick change bore. A cam lock assembly includes a cylindrical body, and a ball head bore radially penetrating the cylindrical body for alignment with the quick change bore. The cylindrical body is receivable in the transgrip arm. The transgrip arm is coupleable with the transgrip spindle assembly by coupling the ball head coupler with the cylindrical body.
Abstract:
A method of operating a closing station includes decoupling a first closing element from a working position of the closing station and moving it away from the working position, bringing a second closing element into the working position, and coupling it into the container transport path at the working position.
Abstract:
An installation for packaging a measured quantity of a liquid product in a corresponding container advancing along a feed path that includes a filling station equipped with a plurality of product dispensers and a capping station located downstream of the filling station for applying a cap to each previously filled container; the dispensers are movable along an axis between a rest position at a rest zone away from the feed path and a working position at a working zone aligned with the feed path; the installation includes a second group of dispensers movable along the axis between a respective rest position at a respective rest zone away from the feed path and a respective working position at a respective working zone aligned with the feed path.
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.

Abstract:
An improved quick-change collet chuck used with an existing single lane capping apparatus for gripping and installing container caps during the automated high-volume filling and capping process. The quick-change collet chuck allows quick and effortless swapping out of different size jaw sets for different size caps and minimizes interruption and downtime during the automated container capping processes. The quick-change collet chuck has a slim profile for low inertia so as not to interfere with high speed operation and accurate servo torquing. Another optional feature is shown in conjunction with the quick-change collet chuck to facilitate reversible operation when it is desirable to include on-the-fly cap removal and removal torque testing on the capping machine. This feature insures that the collet chuck cannot unscrew or spin loose from the spindle shaft after the quick-change collet is already locked in position.
