Abstract

A passive chute assembly includes: a chute configured to receive objects to be dispensed, the chute having an outlet; and a passive dispensing unit attached to the chute outlet. The passive dispensing unit has a staging portion, wherein objects are captured prior to dispensing. The staging portion is movable between a staging position, in which objects may be captured within the staging portion, and a dispensing position, in which the objects may be fed gravimetrically into a receptacle positioned below the dispensing unit. The staging portion includes an adaptive opening that, when the staging portion moves to the dispensing position, opens adaptively corresponding to a diameter of the receptacle.

Claims

1. A passive dispensing chute assembly, comprising:

a chute configured to receive objects to be dispensed, the chute having an outlet;

a passive dispensing unit attached to the chute outlet, the passive dispensing unit having a staging portion, wherein objects are captured prior to dispensing, the staging portion including a gate member movable between a staging position, in which objects may be captured within the staging portion, and a dispensing position, in which the objects may be fed gravimetrically into a receptacle positioned below the dispensing unit;

the dispensing unit further including a release member, the release member being coupled with the gate member, such that movement of the release member from a staging position to a dispensing position moves the gate member from its staging position to its release position;

wherein movement of the release member rotates the gate about an axis that is generally perpendicular to the path followed by objects released from the chute.

2. The chute assembly defined in claim 1, further comprising a spout positioned downstream of the staging portion.

3. The chute assembly defined in claim 2, wherein the spout is attached to the release member.

4. The chute assembly defined in claim 2, wherein the spout comprises a flexible material that enables the spout to conform to receptacles of different diameters.

5. The chute assembly defined in claim 1, wherein the release member is coupled to the gate member such that gravity biases the release member toward the staging position.

6. The chute assembly defined in claim 1, wherein the release member moves relative to the chute as the release member moves between the staging and release positions.

7. The chute assembly defined in claim 1, wherein the release member translates relative to the chute in moving between the staging and release positions.

8. The chute assembly defined in claim 1, wherein the gate is pivotally mounted to the chute.

9. A passive dispensing chute assembly, comprising:

a chute configured to receive objects to be dispensed, the chute having an outlet;

a passive dispensing unit attached to the chute outlet, the passive dispensing unit having a staging portion, wherein objects are captured prior to dispensing, the staging portion including a gate member movable between a staging position, in which objects may be captured within the staging portion, and a dispensing position, in which the objects may be fed gravimetrically into a receptacle positioned below the dispensing unit;

the dispensing unit further including a release member, the release member being coupled with the gate member, such that movement of the release member from a staging position to a dispensing position moves the gate member from its staging position to its release position; and

the dispensing unit further comprising a spout positioned downstream of the staging portion, the spout comprising a flexible material that enables the spout to conform to receptacles of different diameters.

10. The chute assembly defined in claim 9, wherein the gate member moves generally within a plane in moving from the staging to the dispensing position, and wherein the plane is generally normal to a path followed by objects being released from the staging portion.

11. The chute assembly defined in claim 10, wherein the release member is configured to move in a direction generally opposite of the path followed by objects being released.

12. The chute assembly defined in claim 10, wherein the release member is rotatable about an axis that is generally parallel to the path followed by objects being released.

13. The chute assembly defined in claim 9, wherein the spout is attached to the release member.

14. The chute assembly defined in claim 9, wherein the release member is coupled to the gate member such that gravity biases the release member toward the staging position.

15. The chute assembly defined in claim 9, wherein the release member moves in concert with the chute as the release member moves between the staging and dispensing positions.

16. The chute assembly defined in claim 9, wherein the release member moves relative to the chute as the release member moves between the staging and release positions.

17. A passive dispensing chute assembly, comprising:

a chute configured to receive objects to be dispensed, the chute having an outlet;

a passive dispensing unit attached to the chute outlet, the passive dispensing unit having a staging portion, wherein objects are captured prior to dispensing, the staging portion including a gate member movable between a staging position, in which objects may be captured within the staging portion, and a dispensing position, in which the objects may be fed gravimetrically into a receptacle positioned below the dispensing unit;

the dispensing unit further including a release member, the release member being coupled with the gate member, such that movement of the release member from a staging position to a dispensing position moves the gate member from its staging position to its release position;

wherein the gate member moves generally within a plane in moving from the staging to the dispensing position, and wherein the plane is generally normal to a path followed by objects being released from the staging portion; and

wherein the release member is configured to move in a direction generally opposite of the path followed by objects being released.

18. The chute assembly defined in claim 17, further comprising a spout positioned downstream of the staging portion.

19. The chute assembly defined in claim 18, wherein the spout is attached to the release member.

20. The chute assembly defined in claim 18, wherein the spout comprises a flexible material that enables the spout to conform to receptacles of different diameters.

21. The chute assembly defined in claim 17, wherein the release member is coupled to the gate member such that gravity biases the release member toward the staging position.

22. The chute assembly defined in claim 17, wherein the release member moves relative to the chute as the release member moves between the staging and release positions.
