A machine for dispensing dry and moist materials including those which are self-adhering and/or compactible or which tend to agglomerate comprising a material dispensing chute formed at its sides by horizontally reciprocating, expanded metal grid plates which engage and separate material from adjacent material pressing thereagainst for passage through the grids of the plates and metered depositation onto articles or products passing therebeneath. The grid plates have horizontally spaced, downwardly converging upper portions forming a V where the majority of material is separated and horizontally spaced, parallel lower portions forming a narrow transverse width channel which prevents material from loading up between the grid plates in the V, such giving the chute a generally Y-shape in transverse cross-section. Depending on the material being dispensed, the grid plates may be formed from either flat or raised expanded metal grid material preferably having a diamond grid pattern that enhances material separation through a funneling or wedging effect. The grid plates are desirably reciprocated in respective top and bottom tracks by eccentrics in a direction opposite each other for more uniform discharge of material. Either grid plate may be fixed and/or replaced by a solid or part solid/part grid plate, the latter providing a narrower width discharge pattern. Also provided is a power drive motor mount which permits quick and easy removal of the motor to allow cleaning of the machine without subjecting the motor to the cleaning environment.
A material dispensing machine comprising a chute for receiving material to be dispensed, said chute having horizontally spaced sides at least one of which is formed by a grid plate made of expanded metal grid material, mounting means for mounting said grid plate for oscillatory movement, and drive means for effecting such oscillatory movement so that material engaged with the expanded metal grid material of said grid plate is separated from adjacent material for passage through and discharge from said grid plate, said grid plate having an inclined upper portion horizontally spaced from an oppositely inclined upper portion of the other side of said chute and a vertical bottom portion closely spaced from a vertical bottom portion of said other side to form an upwardly opening top portion of said chute which downwardly tapers to a narrow vertical channel portion of said chute.
A material dispensing machine comprising a chute for receiving material to be dispensed, said chute having horizontally spaced sides which are formed by grid plates made of expanded metal grid material, mounting means for mounting said grid plates for oscillatory movement, and drive means for effecting such oscillatory movement so that material engaged with the expanded metal grid material of said grid plates is separated from adjacent material for passage through and discharge from said grid plates, said gird plates having horizontally spaced, downwardly converging upper portions terminating at closely horizontally spaced bottom portions forming a narrow depending channel.
A material dispensing machine comprising a chute for receiving material to be dispensed, said chute having horizontally spaced downwardly converging upper side portions terminating at closely spaced vertical bottom side portions forming a narrow depending channel, grid means forming at least one of said upper and bottom side portions of said chute, and means for horizontally reciprocating said grid means to effect refinement of material passing downwardly through said chute.
A material dispensing machine comprising a chute for receiving material to be dispensed, said chute having horizontally spaced sides at least one of which is formed by a grid plate having a plurality of openings therein for passage of material therethrough, mounting means for mounting said grid plate for oscillatory movement, and drive means for effecting such oscillatory movement so that material engaged by said grid plate is separated from adjacent material for passage through and discharge from said grid plate, said grid plate having an inclined upper portion on one side of said chute horizontally spaced from an oppositely inclined upper portion of the other side of said chute and a vertical bottom portion on said one side closely spaced from a vertical bottom portion of said other side to form an upwardly opening top portion of said chute which downwardly tapers to a narrow vertical channel portion of said chute.
