Cured leaf separator
A leaf removal assembly including a frame comprising a front plate having a feed opening, a leaf stripping assembly mounted on said front plate in front of said feed opening and an upper sprocket wheel comprising a plurality of upper socket grippers extending radially outward of the upper sprocket wheel and being disposed behind the front plate. The leaf removal assembly further includes a lower sprocket wheel comprising a plurality of lower sprocket grippers extending radially outwardly of the lower sprocket wheel and being disposed behind the front plate. At least one of the upper sprocket wheel and the lower sprocket wheel may be adjustably attached to the frame. A process for separating a leaf from a stalk comprising at least one leaf is also included.
1. A method of removing leaf from a collection of stalks of different sizes, the method comprising:
stripping leaf from each stalk by feeding each stalk through a stripping mechanism,
the stripping including,
drawing each stalk between opposing, radially moveable, rotationally fixed cutting edges while biasing the cutting edges radially inward, and
abating cutting of each stalk by limiting radial inward movement of the cutting edges by contacting a stem during the drawing step with a portion of a guide shoe that moves with and extends radially inwardly beyond each cutting edge, and
the feeding including,
gripping an end portion of each stalk between a pair of opposing, rotating grippers while biasing one of the grippers toward the other gripper, the pair of opposing, rotating grippers on an upper wheel and a lower wheel that are rotatably fixed within a cradle housing, the cradle housing extending at least a length of the upper wheel and the lower wheel;
upon an occurrence of a jam from a first stalk, relieving the jam by moving one of the grippers away from the other, while continuing the biasing; and
the feeding further comprising continuously rotating the grippers throughout the gripping, biasing and relieving.
2. The method of claim 1 , wherein the stripping mechanism comprises a spring configured to bias the cutting edges radially inward.
3. A method of removing leaf from a collection of stalks of different sizes, the method comprising:
stripping leaf from each stalk by feeding each stalk through a stripping mechanism,
the stripping including
drawing each stalk between opposing, radially moveable, rotationally fixed cutting edges while biasing the cutting edges radially inward, and
the feeding including,
gripping an end portion of each stalk between a pair of opposing, rotating grippers while biasing one of the grippers toward the other gripper, the pair of opposing, rotating grippers on an upper wheel and a lower wheel that are rotatably fixed within a cradle housing, the cradle housing extending at least a length of the upper wheel and the lower wheel;
upon an occurrence of a jam from a first stalk, relieving the jam by moving one of the grippers away from the other, while continuing the biasing; and
the feeding further comprising continuously rotating the grippers throughout the gripping, biasing and relieving.
4. The method of claim 3 , wherein the stripping further includes abating cutting of each stalk by limiting radial inward movement of the cutting edges by contacting a stem during the drawing step with a portion of a guide shoe that moves with and extends radially inwardly beyond each cutting edge.
5. The method of claim 4 , wherein the stripping mechanism comprises a spring configured to bias the cutting edges radially inward.
6. A method of removing leaf from a collection of stalks of different sizes, the method comprising:
stripping leaf from each stalk by feeding each stalk through a stripping mechanism, the feeding including gripping an end portion of each stalk between a pair of opposing, rotating grippers while biasing a first gripper of the pair of grippers toward a second gripper of the pair of grippers and while biasing the second gripper toward the first gripper, the pair of opposing, rotating grippers on an upper wheel and a lower wheel that are rotatably fixed within a cradle housing, the cradle housing extending at least a length of the upper wheel and the lower wheel;
upon an occurrence of a jam from a first stalk, relieving the jam by moving one of the grippers away from the other, while continuing the biasing; and
the feeding further comprising continuously rotating the grippers throughout the gripping, biasing and relieving.
7. The method of claim 6 , wherein the stripping includes drawing each stalk between opposing, radially moveable cutting edges while biasing the cutting edges radially inward.
8. The method of claim 7 , wherein the stripping includes abating cutting of each stalk by limiting radial inward movement of the cutting edges by contacting a stem during the drawing step with a portion of a guide shoe that moves with and extends radially inwardly beyond each cutting edge.
9. The method of claim 8 , wherein the stripping mechanism comprises a spring configured to bias the cutting edges radially inward.
10. The method of claim 7 , wherein the cutting edges are configured to be rotationally fixed.
