Abstract
A stripper assembly can include a feed wheel, a stripping tire, a drag clutch, and first and second stripping elements. The feed wheel and stripping tire can be mounted for rotation in clockwise (CW) and counter-clockwise (CCW) directions and can contact one another to define a nip through which papers are directed. The drag clutch can be interposed between the stripping tire and the shaft it is mounted upon. The first and second stripping elements can be positioned on the shaft of the stripping tire on opposite sides of the nip. Each of the stripping elements can be configured and positioned to engage papers passing through the nip. The drag clutch is not interposed between either of the first and second stripping elements and the shaft of the stripping tire.
Claims20
A stripper assembly comprising:
- a feed wheel having a first radius and mounted on a first shaft for rotation in a clockwise (CW) direction and in a counter-clockwise (CCW) direction about a longitudinal axis of said first shaft;
- a stripping tire having a second radius and mounted on a second shaft for rotation in the CW direction and in the CCW direction about a longitudinal axis of said second shaft, wherein said feed wheel and said stripping tire contact one another to define a nip through which papers are directed, and wherein said longitudinal axis of said first shaft and said longitudinal axis of said second shaft are a first distance apart along a first axis that is normal to both of said longitudinal axis of said first shaft and said longitudinal axis of said second shaft;
- a drag clutch interposed between said stripping tire and said second shaft, said drag clutch including a radially-outer portion and a radially-inner portion, said drag clutch configured such that said radially-outer portion and said radially-inner portion are fixed together up to a predetermined level of torque and further configured such that said radially-outer portion and said radially-inner portion are rotationally moveable relative to one another in response to torque greater that the predetermined level of torque;
- first and second stripping elements engaged with said second shaft and positioned on opposite sides of said nip, each of said first and second stripping elements being circular and defining respective third and fourth radii, each of said first and second stripping elements configured and positioned to engage papers passing through said nip, and wherein said drag clutch is not interposed between either of said first and second stripping elements and said second shaft;
- an anchor link;
- and
- a first one-way clutch interposed between said radially-inner portion of said drag clutch and said anchor link, said first one-way clutch and said anchor link cooperating to prevent rotation of said radially-inner portion of said drag clutch in one of the CW direction and the CCW direction and permit rotation of said radially-inner portion of said drag clutch in the other of the CW direction and the CCW direction;
- wherein:
- said first one-way clutch further comprises at least one of a first tab and a first notch, said at least one of said first tab and said first notch projecting parallel to said longitudinal axis of said second shaft in a first direction;
- said radially-inner portion of said drag clutch further comprises the other of said at least one of said first tab and said first notch, said other of said at least one of said first tab and said first notch projecting parallel to said longitudinal axis of said second shaft in a second direction opposite to said first direction;
- and
- said at least one of said first tab and said first notch of said first one-way clutch slidably and releasably engages said other of said at least one of said first tab and said first notch of said radially-inner portion of said drag clutch to interlock said first one-way clutch and said radially-inner portion of said drag clutch for concurrent rotation about said longitudinal axis of said second shaft.

- first and second stripping elements engaged with said second shaft and positioned on opposite sides of said nip, each of said first and second stripping elements being circular and defining respective third and fourth radii, each of said first and second stripping elements configured and positioned to engage papers passing through said nip, and wherein said drag clutch is not interposed between either of said first and second stripping elements and said second shaft;
- a second one-way clutch interposed between said radially-inner portion of said drag clutch and said second shaft, said second one-way clutch configured to transmit rotation of said second shaft to said radially-inner portion of said drag clutch in only one of the CW direction and the CCW direction;
- an anchor link;
- and
- a first one-way clutch interposed between said radially-inner portion of said drag clutch and said anchor link, said first one-way clutch and said anchor link cooperating to prevent rotation of said radially-inner portion of said drag clutch in the other of the CW direction and the CCW direction and permit rotation of said radially-inner portion of said drag clutch in the one of the CW direction and the CCW direction, wherein said second one-way clutch and said first one-way clutch are positioned on opposite sides of said drag clutch along said longitudinal axis of said second shaft;
- wherein said second one-way clutch and said first one-way clutch and said drag clutch are connected to one another through a plurality of interlocking tabs and notches that slidably engage one another when said second one-way clutch and said first one-way clutch and said drag clutch are moved relative to one another along said longitudinal axis of said second shaft.
