Methods for controlled dispensing
Devices and methods for controlled dispensation are described herein where such an assembly may generally comprise an index plate having one or more protrusions extending from a surface of the plate, a first actuator configured to translate the plate in a first direction, and a second actuator configured to translate the plate in a second direction different from the first direction. The one or more protrusions may define one or more rows which are arranged upon the plate in a collinear arrangement and may further define one or more columns which are arranged upon the plate at an angle relative to a proximal or distal edge of the plate such that each protrusion is off-set relative to an adjacent protrusion along the column.
1. A method for selective actuation, comprising: translating an index plate in a first direction in proximity to a plurality of bins arranged relative to one another in a plurality of columns of bins and each having a corresponding trigger release arm, wherein the index plate defines a plane having a perimeter border and a plurality of protrusions extending from a surface of the plate entirely within the perimeter border of the plane such that the plurality of protrusions are non-planar relative to the index plate and where the plurality of protrusions define a plurality of rows arranged upon the plate in a collinear arrangement; aligning a single protrusion to a single trigger release arm along the first direction; and translating the index plate in a second direction transverse to the first direction such that the single protrusion engages with the single trigger release arm and actuates a preselected bin which corresponds to the single trigger release arm, wherein the plurality of protrusions further define a plurality of columns which are arranged upon the plate at an angle relative to a proximal or distal edge of the plate such that each protrusion is off-set relative to an adjacent protrusion along the plurality of columns of protrusions which are further arranged to actuate alternating columns from the plurality of columns of bins for dispensing.
2. The method of claim 1 wherein translating an index plate comprises translating the index plate within an enclosure in which the index plate and plurality of bins are secured.
3. The method of claim 1 wherein a distance between the plurality of columns of protrusions is less than a distance between adjacent trigger release arms.
4. The method of claim 1 further comprising releasing a lid upon actuation of the single trigger release arm.
5. The method of claim 4 further comprising sensing a release of the lid from a bin.
6. The method of claim 1 wherein translating an index plate in a first direction comprises activating a first actuator to move the index plate along the first direction.
7. The method of claim 6 wherein translating the index plate in a second direction comprises activating a second actuator to move the index plate along the second direction.
8. The method of claim 1 further comprising translating a second index plate slidingly positioned adjacent to the index plate and in proximity to the plurality of bins, the second index plate having a plurality of additional protrusions extending from a surface of the second index plate.
9. The method of claim 1 further comprising controlling translation of the index plate in the first direction and second direction via a controller.
