Abstract
An ultraviolet (“UV”) emission device may emit energy towards a movable surface of a conveyor system. A housing of the UV emission device may attach to a frame of the conveyor system. A lateral edge of the housing may extend across the moveable surface. The housing and a portion of the moveable surface may be inclined with respect to the frame. A barrier bracket of the UV emission device may support an absorptive barrier along the lateral edge, the absorptive barrier configured to contact the moveable surface. In a first position of the barrier bracket, the absorptive barrier contacts the moveable surface and the barrier bracket activates an interlock switch. In a second position of the barrier bracket, the barrier bracket deactivates the interlock switch. Responsive to deactivation of the interlock switch, a controller may provide a control signal to decrease power to the UV energy emission element.
