AN AUTOMATIC DISPENSING MODULAR ASSEMBLY FOR GRANULES AND METHOD OF OPERATING THEREOF

摘要

The automatic dispensing modular assembly includes plurality of granule dispensing modules to dispense a pre-set quantity of a selectable granular material out of different types of granular materials provided in different dispensing modules. Each granule dispensing module includes a canister sub- assembly (30) and a pneumatic cylinder sub-assembly (40). The canister sub- assembly (30) includes a granule canister (5) and a granule volumetric dozer (16) to dispense consistently and accurately a pre-set quantity of a granular material. The pneumatic cylinder sub-assembly (40) includes a pneumatic cylinder (4) having piston rod (17) capable of imparting forward and backward motion to the granule conveyor (6) coupled to the piston rod (17) of the pneumatic cylinder sub-assembly (40) by means of granule conveyor coupler (15). The granular material is dispensed through granule dispensing tube (20) under pressure of exhaust air flowing through exhaust air conveyor tube (19) when the granule volumetric dozer (16) is brought in vertical alignment with the granule dispensing port (7) and compressed air port (8) due to the forward motion of the granule conveyor (6) imparted to it by the forward motion of the piston rod (17) through granule conveyor coupler (15).
