Abstract

Abstract This invention relates to a web sorting apparatus for receiving and collating sheets from a copying machine. Roll members having a pair of belt members wound thereon are rotated in first one direction to separate and load copies of sheet No. 1 and then the opposite direction to separate and load copies of sheet No. 2. While sheets are not in the loading area they are trapped between layers of a belt on one of the rolls for temporary storage and protection. The operation is repeated until all the pages are loaded between the belt members. At this time the belts separate to unload the collated sets of copies into a receiving tray. By virtue of two separate paths, to the loading station simplex and duplex sorting modes of operation is accomplished.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 239 words
In a reproduction apparatus in which copy sheets reproduced from document information are distributed, an improved sorting apparatus comprising: a frame first roll means positioned on said frame including first and second belt members adapted to receive copy sheets advanced along a path therebetween, second roll means on said frame for receiving one of said belt members arranged along a path which has a copy sheet loading station located at a planar portion of the belt path at which copy sheets are loaded thereon and a third belt member adapted to receive copy sheets subsequent to loading of the sheets on the loading belt member therebetween, drive means for driving said first and second roll means to move said loading belt member past said copy sheet loading station to receive and separate copy sheets by positioning each copy sheet at a separate location on said loading belt member and then moving said loading belt member into loaded contact with another of said belt members to trap copy sheets therebetween, means to reverse said roll drive means at predetermined intervals to move the belt members in an opposite direction to position subsequent copy sheets in overlying relation to sheets previously loaded on said loading belt member to store at least partially completed copy sets on said roll means, means associated with one of said roll means for separating said belt member to unload copy sets into a receiving tray member.
Claim 2
Dependent Claim 239 words
In a reproduction apparatus in which copy sheets reproduced from document information are distributed, an improved sorting apparatus comprising: a frame first roll means positioned on said frame including first and second belt members adapted to receive copy sheets advanced along a path therebetween, second roll means on said frame for receiving one of said belt members arranged along a path which has a copy sheet loading station located at a planar portion of the belt path at which copy sheets are loaded thereon and a third belt member adapted to receive copy sheets subsequent to loading of the sheets on the loading belt member therebetween, drive means for driving said first and second roll means to move said loading belt member past said copy sheet loading station to receive and separate copy sheets by positioning each copy sheet at a separate location on said loading belt member and then moving said loading belt member into loaded contact with another of said belt members to trap copy sheets therebetween, means to reverse said roll drive means at predetermined intervals to move the belt members in an opposite direction to position subsequent copy sheets in overlying relation to sheets previously loaded on said loading belt member to store at least partially completed copy sets on said roll means, means associated with one of said roll means for separating said belt member to unload copy sets into a receiving tray member.
Claim 3
Dependent Claim 21 words
Apparatus according to claim 1 wherein said tray member is reciprocated at predetermined intervals to effect separation of the copy sets.
Claim 4
Dependent Claim 31 words
Apparatus according to claim 1 including gate means positioned in the sheet path to direct the copy sheets along an alternate path to enter the sheet loading zone in inverted form.
