Abstract
Abstract A paper handling system is used in combination with a duplicator of the type having a printing station and means for conveying printed sheets from the printing station. The paper handling system includes a gravity feed accumulator for receiving sheets from the sheet conveying means and collecting them in a set, a finishing station positioned at the lower level of the accumulator for receiving collected sets from the accumulator and including a stapling device for binding together the sheets of the set, an elevator which communicates with the finishing station to receive bound pamphlets therefrom, and a stacking device which is positioned above the finishing station and communicates with the elevator for receiving pamphlets and arranging them in a stack. The stacking device includes an upper level stacking station, a discharge station located beneath the stacking station, and a movable tray which is capable of being indexed between the upper level and the discharge station. The discharge station includes a discharge conveyor which transports the offset stack of sets of sheets from the tray to a shelf positioned at an optimum height above the floor of the work area within which the paper handling system is located.

Claim 1
Independent Claim
338 words
For use with a duplicating device of the type having printing means for imparting an image onto single sheets of paper, and conveying means including a sheet feed station for conveying sheets from the printing means to the sheet feed station, a paper handling system comprising: a gravity feed accumulator for receiving sheets serially from a sheet feed station and collecting them into a set, said accumulator having an intake for communicating with a sheet feed station to receive sheets therefrom, an outlet, positioned at a lower elevation than and sidewardly from said intake, through which sets of collected sheets leave said accumulator, and means joining said intake and said outlet and positioned at an elevation therebetween, for repetitively accumulating sheets entering said intake into a set and conveying sets sidewardly from said intake to said outlet; a finishing station positioned below said intake and communicating with said outlet, said finishing station having transition means for conveying sets sidewardly from said outlet then rearwardly; elevator means having an inlet end located rearwardly of and communicating with said transition means, means for conveying pamphlets upwardly from said inlet, and an outlet end located above said inlet for conveying pamphlets forwardly from said conveying means; top-loading stacker means superposed to said finishing station and having an upper level communicating with said outlet end, a substantially horizontal tray and means for indexing said tray in a vertical direction downwardly from said upper level such that a first bound pamphlet may be conveyed forwardly from said outlet means, placed upon said tray at said upper level, and said table indexed downwardly repeatedly so that successive pamphlets may be stacked one on top of another; and discharge conveyor means communicating with said stacker means and said tray and having a discharge station positioned exteriorly and forwardly of said stacker means for transporting a stack of bound pamphlets from said tray to said discharge station, said discharge station being located at an elevation intermediate the elevations of said upper level and said finishing station.

Claim 6
Dependent Claim
246 words
For use with a duplicating system which produces sets of printed sheets in serial paginated sequence for binding into pamphlet form, a paper handling system comprising: receiving means for receiving printed sheets; accumulator means located adjacent said receiving means for accumulating sheets into pamphlet-defining sets; conveying means for conveying sets one at a time, as accumulated, sidewardly away from said accumulator; finishing means for receiving sets of sheets sidewardly from said conveyor means and ejecting sets of sheets received in a rearward direction; elevator means having an inlet end and an outlet end for receiving sets of sheets ejected rearwardly from said finishing means through said inlet end and conveying sets of sheets along an arcuate path which extends rearwardly from said inlet, thence upwardly, and thence forwardly through said outlet end; stacking means substantially superposed to said finishing means including a substantially horizontal tray for receiving sets of sheets from said outlet end of said elevator means and stacking sets into a stack upon said tray while lowering said tray to maintain a top surface of a stack upon said tray level with said outlet end of said elevator means; discharge means having an elevation intermediate said conveying means and said outlet end for removing a stack from said tray and discharging a removed stack in a forward direction; and a shelf substantially coplanar with said discharge means for receiving a removed stack from said discharge means and presenting a removed stack to a user.
Claim 7
Dependent Claim
