Abstract: A capping apparatus 1 includes torque sensor 12 which detects an output torque when a chuck 7 is driven for rotation by a motor 9. Initially, a cap 5 is held by the chuck 7. The cap 5 is fitted over a mouth of a vessel 2, and then the chuck 7 is rotated through one revolution in a clamping direction. A resulting output torque is detected by the torque sensor 12, and the output torque rapidly increases at the position where the threads on the cap 5 and the vessel 2 abut against each other (an incipient position of meshing engagement P). The cap 5 is rotated through a given angle of rotation as referenced to the incipient position of meshing engagement P, thus threadably engaging the cap 5 with the vessel 2. The invention allows a uniform clamping of cap 5 at the completion of the capping operation.

Abstract: A gripper includes grip members which are mounted on a first rotary shaft and a second rotary shaft, respectively, so as to be opened and closed. An engaging pawl is formed on an upper surface of the grip member. Both shafts are elevatable in an integral manner. A receptacle member is disposed below an exit star-wheel, and is arranged to rotate integrally with the star-wheel. The gripper is located below the flange of the vessel when receiving the vessel. Accordingly, the engaging pawl cannot contact the flange. When the vessel is depressed by the capping head during a capping operation, the engaging pawl engages the vessel. When the vessel is discharged, the vessel remains suspended above the receptacle member, and the gripper then descends to place the vessel on the receptacle member and to disengage the engaging pawl of the gripper. Accordingly, there is no scarring of the vessel when the vessel is introduced into and discharged from the screw capper, and a stable conveyance of vessels is enabled.

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.
