Abstract

Abstract Apparatus for accumulating stacks of sliced material successively cut from an elongated mass comprises a platen mounted on a vertically movable carriage and means for moving the carriage downwardly as the slices are accumulating on said platen. After an accumulation of a desired number of slices in a stack, the platen is rapidly moved to release and discharge the stack and the carriage is moved upwardly on a return stroke to a position ready for the next accumulation cycle.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 210 words
Apparatus for cutting successive slices from an elongated mass comprising a knife rotatable around a cutting path, means for feeding said mass at a substantially constant rate along a downward feed path intersecting said cutting path to cause successive slices to be cut from said mass, means spaced below said cutting path for accumulating a stack of the slices successively cut from said mass, means for moving said accumulating means downwardly at a rate infinitely variable within a range to equal substantially the rate at which said mass is fed along said feed path, thereby maintaining a substantially constant dropping distance for successive slices cut from said mass, said moving means including a carriage mounted for vertical reciprocation on downward accumulation strokes and upward return strokes, and including a motor and clutch for driving said carriage on said downward strokes and resilient biasing means for moving said carriage upwardly on said return strokes, said accumulating means comprising a platen rotatably movable between a substantially horizontal accumulating position during a downstroke accumulating a stack of the slices and a releasing position for releasing the stack, drive means for moving said platen from said accumulating position to said releasing position adjacent the lower end of a downward stroke of said moving means.
Claim 2
Dependent Claim 210 words
Apparatus for cutting successive slices from an elongated mass comprising a knife rotatable around a cutting path, means for feeding said mass at a substantially constant rate along a downward feed path intersecting said cutting path to cause successive slices to be cut from said mass, means spaced below said cutting path for accumulating a stack of the slices successively cut from said mass, means for moving said accumulating means downwardly at a rate infinitely variable within a range to equal substantially the rate at which said mass is fed along said feed path, thereby maintaining a substantially constant dropping distance for successive slices cut from said mass, said moving means including a carriage mounted for vertical reciprocation on downward accumulation strokes and upward return strokes, and including a motor and clutch for driving said carriage on said downward strokes and resilient biasing means for moving said carriage upwardly on said return strokes, said accumulating means comprising a platen rotatably movable between a substantially horizontal accumulating position during a downstroke accumulating a stack of the slices and a releasing position for releasing the stack, drive means for moving said platen from said accumulating position to said releasing position adjacent the lower end of a downward stroke of said moving means.
Claim 3
Dependent Claim 58 words
The apparatus of claim 1 wherein said accumulating means comprises a plurality of such platens extending outwardly at different angles from a common shaft mounted for rotation on said carriage means, and drive means including means for rotatably indexing said shaft between said accumulating position and said releasing position successively for each of said platens on said shaft.
Claim 4
Dependent Claim 83 words
The apparatus of claim 2 wherein said accumulating means includes a second shaft mounted for rotation on said moving means spaced horizontally from said common sHaft, a plurality of said platens extending outwardly at different angles from said second shaft, pairs of platens from each shaft cooperating to form a horizontal receiver for a stack of slices as they are cut, said indexing means including means for rotatably indexing said second shaft in opposite directions to said first mentioned shaft in synchronism therewith.
Claim 5
Dependent Claim 27 words
The apparatus of claim 3 wherein said indexing means comprises means responsive to a counted number of slices for indexing said shafts to discharge an accumulated stack.
Claim 6
Dependent Claim 32 words
The apparatus of claim 4 wherein said indexing means is operable to discharge an accumulated stack of slices when said moving means is adjacent a lower level away from said cutting path.
Claim 7
Dependent Claim 24 words
The apparatus of claim 1 including means for dampening the movements of said moving means adjacent the end of its downward and return strokes.
