Zone control systems, conveyor systems, and methods

A conveyor system comprising:

• a conveyor frame;
• one or more rollers disposed on or within the conveyor frame, wherein at least one of the rollers comprises:
• a drive portion;
• and
• a driven portion configured to be driven by the drive portion when the drive portion and the driven portion are operably engaged;
• a spring disposed between the drive portion and the driven portion, wherein the spring is configured to transition between an extended state, such that the drive portion and the driven portion are separated by a gap and refrain from operably engaging, and a compressed state, such that the drive portion and the driven portion are operably engaged;
• and
• an actuator operably engaged with one or more of the roller and the spring, wherein the actuator is configured to actuate the spring between the extended state and the compressed state.

A method of using a zone control system, the method comprising:

• inflating, by an air supply inlet, an air bladder coupled to an actuating bracket, such that the actuating bracket compresses a spring separating a drive portion of a roller from a driven portion of the roller;
• engaging the drive portion and the driven portion such that the drive portion drives the driven portion of the roller;
• and
• deflating, by the air supply inlet, the air bladder, such that the actuating bracket extends a spring separating the drive portion of the roller from the driven portion of the roller.
