Abstract
A release assembly is mounted adjacent a track to release selected ones of a plurality of gripper clamps movable along the track past the release assembly. The release assembly includes a cam mounted for movement relative to the track between a first position in which the cam is engageable by a gripper clamp moving along the track, to open the gripper clamp, and a second position in which the cam is spaced from and not engageable by the moving gripper clamp. The release assembly includes a rotary actuator selectively operable to move the cam between its first and second positions. The release assembly includes an overcenter linkage for blocking movement of the cam out of its first position toward its second position upon engagement by a moving gripper clamp.
