Abstract
A feed system for feeding light-weight materials, such as tobacco, into large blending and/or bulking bins. The present invention resides primarily in a novel, light-weight feed system comprising a trolley and a shuttle conveyor adapted to reciprocatingly feed rapidly in either a longitudinal or lateral direction with a minimum amount of inertia during acceleration and deacceleration. A feed conveyor deposits said material onto the shuttle conveyor, said feed conveyor comprising drive elements adapted to synchronize movement of the feed conveyor with movement of the shuttle conveyor. The shuttle conveyor, at least in the X direction, is unencumbered mechanically by the feed conveyor.
Claims7
A blending and bulking bin assembly comprising
- (a) an elongated, rectangular bin having longitudinal X and lateral Y directions;
- (b) a trolley movable longitudinally with respect to the bin;
- (c) a shuttle conveyor carried by said trolley and moveable laterally on the trolley with respect to the bin;
- (d) an endless conveyor belt carried by said shuttle conveyor;
- (e) a feed conveyor adapted to feed tobacco onto said shuttle conveyor belt, said feed conveyor having a movable discharge end;
- (f) drive means mechanically independent from the shuttle X direction of movement affixed to said feed conveyor discharge end to move said discharge end laterally to coincide with lateral movement of the shuttle conveyor.
A blending and bulking bin assembly for tobacco comprising
- (a) at least two side-by-side rectangular bins having the same longitudinal and lateral directions;
- (b) a trolley movable longitudinally with respect to said bins;
- (c) a shuttle conveyor carried by said trolley and moveable laterally on the trolley with respect to the bin;
- (d) an endless conveyor belt carried by said shuttle conveyor
- (e) a pivoting feed conveyor having a fixed pivot point and a feed belt discharge end removed from the pivot point and movable with respect to said pivot point;
- (f) a laterally extending track means;
- and
- (g) guide means moveable on said track means affixed to said feed belt discharge end maintaining the lateral position of said discharge end coincident with the lateral position of said shuttle conveyor belt.
