Abstract
A feeder conveyor system having a frame, an actuator with a fixed element and a moving element, and a telescoping assembly. The telescoping assembly has a first member having a first end connected to an actuator output and a first spring seat, and a second member slidably connected to the first member and having a second end and a second spring seat. The second member is movable relative to the first member between a retracted position in which the second end is relatively close to the first end, and an extended position in which the second end is relatively far from the first end, a spring between the first spring seat and the second spring seat, a linkage between the first member and the second member, and a position sensor connected to the linkage and configured to generate a signal indicating a relative position between the first and second members.
