Abstract
Abstract An apparatus for accumulating sheets from a secondary source and changing their conveyance direction 90°. The accumulator is a group of vertically stacked bins that discharge batchwise and are loaded from the secondary source alternately by way of a diverter. Discharge is synchronous with a directionally constant primary sheet source.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
267 words
An apparatus for accumulating and directionally reorienting the movement of sheets being fed from a supplemental source along a supplemental sheet feed path defined by a supplemental sheet feeding means into a primary sheet feed path defined by a primary sheet feeding means which feeds sheets from a primary source, said accumulating and directionally reorienting apparatus comprising: A. means defining a plurality of vertically stacked sheet collecting bins disposed in overlying relationship to said primary sheet feed path, each of said bins having 1. an inlet opening extending along one side thereof that is perpendicular to the direction of said supplemental sheet feed path for receiving sheets from said supplemental source along said supplemental sheet feed path, and 2. a discharge opening on another side thereof that is disposed perpendicular to said one side for discharging sheets into said primary sheet feed path, B. sheet directing means mounted adjacent said inlet openings of said bins for directing sheets successively into said plurality of bins, C. ejecting means disposed in each of said bins for ejecting sheets therefrom successively through said discharge openings, and D. control means for operating said sheet directing means and said ejecting means in a predetermined timed sequence to permit a predetermined number of sheets to enter each of said bins and to cause said ejecting means to eject said sheets from said bins successively when said predetermined number of sheets has been fed to said bins, whereby sheets from said supplemental source can be associated with sheets from said primary source at a location disposed downstream from said accumulating and directionally reorienting apparatus.
Claim 2
Independent Claim
267 words
An apparatus for accumulating and directionally reorienting the movement of sheets being fed from a supplemental source along a supplemental sheet feed path defined by a supplemental sheet feeding means into a primary sheet feed path defined by a primary sheet feeding means which feeds sheets from a primary source, said accumulating and directionally reorienting apparatus comprising: A. means defining a plurality of vertically stacked sheet collecting bins disposed in overlying relationship to said primary sheet feed path, each of said bins having 1. an inlet opening extending along one side thereof that is perpendicular to the direction of said supplemental sheet feed path for receiving sheets from said supplemental source along said supplemental sheet feed path, and 2. a discharge opening on another side thereof that is disposed perpendicular to said one side for discharging sheets into said primary sheet feed path, B. sheet directing means mounted adjacent said inlet openings of said bins for directing sheets successively into said plurality of bins, C. ejecting means disposed in each of said bins for ejecting sheets therefrom successively through said discharge openings, and D. control means for operating said sheet directing means and said ejecting means in a predetermined timed sequence to permit a predetermined number of sheets to enter each of said bins and to cause said ejecting means to eject said sheets from said bins successively when said predetermined number of sheets has been fed to said bins, whereby sheets from said supplemental source can be associated with sheets from said primary source at a location disposed downstream from said accumulating and directionally reorienting apparatus.
Claim 3
Dependent Claim
46 words
An apparatus as set forth in claim 1 wherein said sheet directing means comprises deflector means mounted for movement between alternate positions in which said deflector means directs sheets from said supplemental sheet feed path successively into said inlet openings of any one of said bins.
Claim 4
Dependent Claim
65 words
An apparatus as set forth in claim 2 wherein said means for directing sheets alternately into each of said bins comprises deflector means mounted adjacent said inlet openings of said bins, said deflector means being pivotally mounted to oscillate between first and second positions in which sheets are directed from said supplemental sheet feed path alternately into one or the other of said inlet openings.
Claim 5
Dependent Claim
48 words
An apparatus as set forth in claim 1 wherein said plurality of vertically stacked bins comprises a pair of upper and lower bins, and said means for directing sheets into said bins comprises means for directing said sheets alternately into said upper and lower each of said bins.
Claim 6
Dependent Claim
24 words
An apparatus as set forth in claim 3 wherein said ejecting means comprises means in each of said bins for ejecting sheets therefrom alternately.
Claim 7
Dependent Claim
48 words
A apparatus as set forth in claim 5 wherein said ejector means comprises pusher means movably mounted in each of said bins adjacent the side of said bins opposite said discharge openings, and drive means for moving said pusher means alternately toward and away from said discharge openings.
Claim 8
Dependent Claim
55 words
A apparatus as set forth in claim 6 wherein said drive means comprises means interconnecting said pusher means in each of said bins to operate said pusher means asynchronously so that one of said pusher means is moving in an ejecting direction while the other of said pusher means is moving in a retracting direction.
Claim 9
Dependent Claim
107 words
An apparatus as set forth in claim 7 wherein said pusher means for both of said bins are mounted in vertical alignment, and said drive means comprises a rack connected to each of said pusher means in vertically spaced relationship, a gear rotatably mounted between and engaged with both said racks, and means for driving said gear alternately in opposite directions so that rotation of said gear in one direction moves said racks and said pushers simultaneously in a first sequence of opposite directions, and rotation of said gear in the opposite direction moves said racks and said pushers simultaneously in a second sequence of opposite directions.
Claim 10
Dependent Claim
108 words
An apparatus as set forth in claim 3 wherein said pair of bins comprises A. a first substantially flat sheet forming the bottom of said lower bin, B. a second substantially flat sheet mounted in overlying relationship with said first sheet and forming the bottom of said upper bin, and defining with said first sheet said inlet and discharge openings into and out of said lower bin, and C. a third substantially flat sheet mounted in overlying relationship with said second sheet and forming a cover for said upper bin, and defining with said second sheet said inlet and discharge openings into and out of said upper bin.
Claim 11
Dependent Claim
59 words
An apparatus as set forth in claim 9 wherein each of said sheets are pivotally mounted about a common axis so that each sheet can be raised from a substantially horizontal position to a substantially vertical position to permit jams in either of said bins or in said primary sheet feed path beneath said lower bin to be cleared.
Claim 12
Dependent Claim
30 words
An apparatus as set forth in claim 10 wherein each of said bins is provided with stop means on the side thereof opposite said inlet openings to register incoming sheets.
Claim 13
Dependent Claim
40 words
An apparatus as set forth in claim 11 wherein each of said bins is provided with reverse stop means on the side thereof adjacent said inlet opening to prevent sheets entering said bins from bouncing back into said inlet openings.
Claim 14
Dependent Claim
38 words
An apparatus as set forth in claim 12 wherein both said stop means and said reverse stop means comprise upstanding flanges extending along the sides of said first and second sheets adjacent to and opposite said inlet openings.
Claim 15
Dependent Claim
41 words
An apparatus as set forth in claim 13 wherein said second and third sheets are provided with elongate slots which accommodate said upstanding flanges on said first and second sheets respectively when all said sheets are in said substantially horizontal position.
