ABSTRACT:
A capping machine (10) and method for installing a cap (12) having a threaded portion onto a container (14) having a threaded portion, the threaded portion of the cap corresponding to the threaded portion of the container, the capping machine having a rotatable turret (20) and a rotatable cap chuck (16) which grips the cap and positions the cap on the container. The cap chuck is rotated by a spindle (22) driven by a servo motor (24) at adjustable and reversible rotational velocities independent of the rotational velocity of the turret. The number of rotations of the cap is determined by monitoring the number of rotations of the servo motor compared to the number of rotations of the turret and is transmitted to a spindle drive control(70). The torque imparted to the cap is monitored by a torque monitor (50) and is transmitted to the spindle drive control. The rotational velocity of the cap is adjustable in response to the compared monitored number of rotations and monitored torque. The capped container is released from the cap chuck after a selected number of rotations of the cap onto the container has been made. Caps applied outside a selected range of monitored torques and number of rotations are tracked and rejected.
