Conveyor Belt Alignment Control

April 8, 2014

Conveyor Component’s Model VA belt alignment control protects valuable conveyor belts from severe damage caused by belt misalignment, prevents costly downtime, and increases production. Designed for use on bucket elevators, the Model VA ensures that belts are tracking properly. Normally installed in pairs on each side of the conveyor belt near the head pulley and/or the tail pulley, these heavy-duty controls consist of a conveyor roller with sealed bearings, four-bar linkage, and a double pole/double throw microswitch. The roller detects any belt run-off and will trigger the first pole of the microswitch to sound a warning alarm, illuminate an indicator light, or stop the conveyor completely when the vertical belt strays beyond 10° from horizontal. The second pole is triggered when the belt strays 25° from horizontal and can be wired to stop the conveyor motor. To eliminate false signals the controls should be mounted about one inch away from the belt. For high-speed conveyors a breakaway mount is recommended. In the event of a run-off, the control unit performs its job of shutting down the conveyor and the breakaway mount allows the control itself to get out of the way of damage.
