ABSTRACT:
A clutch and declutch assembly is disclosed for live conveyors that is particularly suitable for conveyors having sections of zones. The clutch assembly has a clutch biasing spring and nut assembly which causes inner and outer driven clutch members to frictionally engage the driving clutch member. The clutch also has a torque limiting feature and a declutching feature. Declutching is performed by expanding a bladder or a hydraulic cylinder, causing a clutch release plate to axially move the outer driven clutch member to disengage with the driving clutch member. A zoned live conveyor is obtained by using at least one live roller, sensor and valve in each zone. When the presence of a load unit in a zone is sensed, a sensing signal is sent to a central control unit, which in turn operates a valve to expand a bladder or cylinder that axially move the clutch release plate to declutch the roller. A variety of control logics can be programmed into the control unit and are easily changed.
