VIBRATORY FEEDER FOR GRANULAR MATERIALS.

摘要

In order to convey granular material (14) from an upstream processing location, a vibratory feeder (10) includes a conveyor (12) having an inlet end (12a) and an outlet end (12b) disposed in spaced apart relation. The conveyor (12) has the inlet end (12a) disposed in a position to receive the material (14) from an outlet (16) of a source (18) of the material by way of gravity. The vibratory feeder (10) utilizes an unbalanced motor (28) for vibrating the conveyor (12) to apply a vibratory force causing the material (14) to be conveyed from the inlet end (12a) to the outlet end (12b) thereof. The transfer of the material from the source (18) to the conveyor (12) is controlled by using a receptacle (20) having a valve (22) for dispensing the material in the receptacle (20) at the inlet end (12a) of the conveyor (12). Specifically, the receptacle (20) receives the material (14) from the source (18) by gravity and the valve (22) opens and closes dependent upon accumulation of the material (14) in the receptacle (20).
