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 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.
Abstract:
A device for closing containers, particularly bottles, with screw caps, having at least one rotatably drivable closing head in which a closure-specific closing element is exchangeably retained, a positive-fit quick-change mechanism for the respective closing element is embodied in the closing head, and in the release state of the quick-change mechanism the closing element can be laterally removed or inserted essentially perpendicular to the rotational axis of the closing head.
Abstract:
A capping head (2) for an apparatus (1) for capping containers (4) comprises a first cap fastening assembly, an additional cap fastening assembly (16) configured to fasten a different type of cap to a container aperture, detachable connecting means for detachably connecting the additional cap fastening assembly (16) to the first cap fastening assembly (12) to convert the capping head (2) from a first type of cap to a different type of cap, wherein the detachable connecting means comprise a trap cavity (17) formed in an external surface (18) of the first cap fastening assembly (12) and adapted to receive a corresponding latch member (19) of the additional cap fastening assembly (16) to lock the latter with respect to the capping head (2).
Abstract:
A device is provided for interconnecting a support and a connector through 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 support as a user re-connects the unit back to the support. Methods of releasing and re-connecting the unit to the support 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:
A screw-tightening spindle comprising a drive sleeve associated with a chuck comprising a cylindrical support member fitted with moving jaws, the cylindrical support member being provided externally with at least one stud extending radially outwards, the sleeve including at least one slot having a first segment opening out in a free edge of the sleeve and a second segment having an end portion forming an angle relative to the sleeve suitable for retaining the stud in the end portion of the slot when the stud is engaged therein, the sleeve being fitted with a ring having at least one stop extending radially inwards and received in the slot, the ring being mounted on the sleeve to slide between a locking position in which the stop extends in the first segment of the slot in register with the second segment, and an unlocking position in which the stop is retracted into a third segment of the slot.
Abstract:
A collet to be used in conjunction with a container capping device used primarily in the packaging industry, more particularly for gripping threaded container caps in preparation for the rotation of the caps onto threaded containers. The structure comprises separately pivoting segments for engaging the container cap without significant flexture of the segments.
Abstract:
A coupling mechanism for interconnecting a drive spindle and a capping chuck, the mechanism including a coupling hub internally threaded for fastening to the spindle. A collar is disposed around the hub, and the hub has an arcuate groove in which a spring is positioned and retained by a removable plate. The hub has lugs integral therewith extending into receiving slots in a floating ring positioned in the collar below the hub. The floating ring is elliptically shaped for lateral movement relative to the collar along a first axis, and has feet integral therewith extending into keyways in a coupling member laterally movable relative to the ring along a second axis right angularly related to the first axis. The coupling member drives a chuck sleeve through a torsion spring to release the closure upon achieving a predetermined degree of tightness on a container.
