Abstract

The arrangement shown in the drawing is a document holding station for a paper document collator, which requires only one reading station to perform the usual collator functions of sequence checking, selecting, merging and matching, and is particularly advantageous when the associated reading and recognition system is relatively complex and/or expensive. The transport system comprises a plurality of driven belts which thread paths over suitable pulleys or rollers, as shown.

Paper Document Collator

The arrangement shown in the drawing is a document holding station for a paper document collator, which requires only one reading station to perform the usual collator functions of sequence checking, selecting, merging and matching, and is particularly advantageous when the associated reading and recognition system is relatively complex and/or expensive. The transport system comprises a plurality of driven belts which thread paths over suitable pulleys or rollers, as shown.

Documents are loaded into two feed hoppers, not shown. The separator and aligner sections associated with each feed hopper are operated from a clutched drive. Each feeding system is individually clutched and normally keeps a queue of documents ready to enter the read station 3 via the main belt transport. A document sensor in the document feeding channel signals the clutched drive to stop at such a time as to leave a document leading edge in close proximity to the read drum 5 transport pinch point.

In the drawing, the primary hold in the belt transport system is shown in dot- dash lines and is furthest from the viewer, i.e., is next to the face plate of the machine. The belt system shown in solid lines is next further out, and second hold in the belt system is shown in dash lines and is the closest to the viewer.

Data read from the previous document normally decides which of the two feeding system drives will be energized, thus calling in the next document to be read. A selector blade 7 transfers to direct the document leaving the read drum into either the primary hold or secondary hold transport. (If the first document from the primary feed is transported into the hold station designated primary hold, this station will then transport all documents from the primary feed in performing collating functions.)

If the document entering the primary hold transport is to be held rather than fed on toward the stackers, the transport decelerates to a stop when the leading edge of the document in it reaches a sensor near the exit merge point of the hold stations. The selector transfers to deflect the next document to the secondary hold station. Meanwhile, the secondary feed has been energized via the separator-aligner clutch drive to feed a document onto the read drum. Data read from this document, when compared with the primary document being held, will determine which feed and associated hold station will be activated next.

The drive for the hold station transport belts comes from the read drum or main transport belt. This is done to achieve minimum velocity mismatch at the hold station entry and exit points, to avoid crumpling or tearing the documents. The primary hold transport belts and idlers are in a different plane than the main transport belt, and the secondary hold station belts and idlers are in a third plane, as explained above.

To illustrate the use of this transport, consider a typical merging operation. When merging, the collator comb...
