Abstract
Abstract A sheet handling machine having the dual capability of either collating or sorting sheet material into individual booklets or collations. The machine has a plurality of sheet receiving bins arranged within a rotary drum operatively associated with infeed and outfeed locations of the machine. The machine includes a conveyor for depositing sheets into the bins, and rotary extracting means located adjacent the bins for extracting sheets from the bins. Appropriate controls are provided to cause the rotary drum to be selectively operable in a predetermined sequence. In a sorting mode of operation, successive copies of the first page of a booklet are fed into successive bins until each bin contains one copy. Thereafter, successive copies of each successive page of the booklet are fed into each bin until each bin contains a completed booklet. Thus, as many booklets are simultaneously formed as there are bins. In the collating mode, each bin is automatically loaded with a predetermined number of the same page of the booklet, and a single sheet from each bin is extracted and conveyed to a receiving station to form a single completed booklet.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
270 words
A combined sorting and collating machine selectively operable in a plurality of modes of operation in which a plurality of copy sheets are assembled into booklets, said machine comprising: means defining an infeed location and an outfeed location; a rotatable drum having a plurality of bins for storing copy sheets, said bins being angularly arranged about the drum; conveyor means operatively associated with said plurality of bins for conveying copy sheets seriatim from said infeed location to said plurality of bins; rotatable withdrawing means disposed adjacent said drum for removing copy sheets from the bins of said drum; a first control means operatively connected to said drum for rotatably actuating said drum to receive copy sheets in a sequential manner in a predetermined number of said bins in order to assemble in each predetermined bin a booklet, thereby defining a machine sorting mode in which the number of booklets corresponds to said predetermined number of bins; a second control means operatively connected to said drum and said withdrawing means for rotatably actuating said drum and said withdrawing means to extract copy sheets in a sequential manner from a predetermined number of bins in order to successively assemble booklets comprising one sheet from each predetermined bin, thereby defining a machine collating mode in which the number of sheets in each booklet corresponds to said predetermined number of bins; and selector means operatively associated with both said first and second control means, respectively, for selecting which of said first or second control means is operable, whereby said machine is selectively operable in either said sorting mode or said collating mode of operation.
Claim 2
Dependent Claim
270 words
A combined sorting and collating machine selectively operable in a plurality of modes of operation in which a plurality of copy sheets are assembled into booklets, said machine comprising: means defining an infeed location and an outfeed location; a rotatable drum having a plurality of bins for storing copy sheets, said bins being angularly arranged about the drum; conveyor means operatively associated with said plurality of bins for conveying copy sheets seriatim from said infeed location to said plurality of bins; rotatable withdrawing means disposed adjacent said drum for removing copy sheets from the bins of said drum; a first control means operatively connected to said drum for rotatably actuating said drum to receive copy sheets in a sequential manner in a predetermined number of said bins in order to assemble in each predetermined bin a booklet, thereby defining a machine sorting mode in which the number of booklets corresponds to said predetermined number of bins; a second control means operatively connected to said drum and said withdrawing means for rotatably actuating said drum and said withdrawing means to extract copy sheets in a sequential manner from a predetermined number of bins in order to successively assemble booklets comprising one sheet from each predetermined bin, thereby defining a machine collating mode in which the number of sheets in each booklet corresponds to said predetermined number of bins; and selector means operatively associated with both said first and second control means, respectively, for selecting which of said first or second control means is operable, whereby said machine is selectively operable in either said sorting mode or said collating mode of operation.
Claim 3
Dependent Claim
64 words
The combined sorting and collating machine of claim 1, further comprising corner separator for separating top sheet from the remaining sheets when said sheets are being withdrawn from their respective bins, said separator means being disposed in each bin of said drum, and actuating means for setting each corner separator means to allow the withdrawal of one sheet at a time from each bin.
Claim 4
Dependent Claim
30 words
The combined sorting and collating machine of claim 2, wherein said actuating means is operatively connected to said drum for cyclically rotating said drum through at least one complete revolution.
Claim 5
Dependent Claim
80 words
The combined sorting and collating machine of claim 2, wherein said corner separator means comprises a pair of spaced apart corner separators, each separator being individually movable from a first position to a second position, biasing means for urging the corner separators to said first position, and camming means disposed adjacent the separator for moving the separators to the second position when actuated, said camming means being actuated by said actuating means which is operatively connected to said camming means.
Claim 6
Dependent Claim
56 words
The combined sorting and collating machine of claim 4, wherein said corner separator means further comprises extension members which are each connected to a corner separator and which moves into rotative contact with said camming means as the drum rotates, when said camming means is engageably actuated by said actuating means for contacting said extension members.
Claim 7
Dependent Claim
66 words
The combined sorting and collating machine of claim 1 further comprising third control means operatively connected to said drum for rotatably actuating said drum to receive successive pluralities of copy sheets in respective successive bins, thereby defining a machine loading mode, and said selector means further operatively associated with said third control means for selecting which of said first, second or third control means is operable.
