Abstract
A buffer unit is configured to store and transfer adhesive particulate to at least one adhesive melter. The buffer unit includes a buffer bin defining an interior space configured to hold a bulk supply of adhesive particulate with an agitator plate positioned within the housing at a non-horizontal orientation. A vibration generating mechanism is coupled to the agitator plate so that vibration is transmitted into the adhesive particulate to form a flow of fluidized adhesive particulate which flows toward at least one pump inlet. The buffer unit breaks up clumps of coalesced adhesive particulate to avoid clogging the pump inlet, while also ensuring that all adhesive particulate in the buffer bin can be removed at the pump inlet. Additionally, makeup air used by pumps to generate vacuum at the pump inlet does not need to be drawn through the entire bulk supply of adhesive particulate.
