Abstract: 1488133 Sheet ordering apparatus TOKYO SHIBAURA ELECTRIC CO Ltd 26 Sept 1974 [28 Sept 1973] 41854/74 Heading B8R Apparatus for sorting banknotes into a first group comprising fit notes (normal notes and soiled notes) and a second group comprising unfit notes (those of the wrong denomination, invalid notes and very soiled notes) includes a feeder 2 for receiving batches of notes and forwarding individual notes to a conveyer 3, a detector 5 for detecting fit and unfit notes and a deflector 6 for sorting the notes so detected. The original bundles of notes comprise sorting cards upon which the results of a counting operation on the notes are recorded. The feeder.-The banknotes are initially received in batches of 100 each batch being surrounded by a strap. The strap is removed and inserted into inlet 51, Fig. 7, where it is conveyed by conveyer 52 past a strap detector 53 to a printer 54 which impresses the strap with data concerning the batch. The strap is then received between tapes from reel 55a and 55b and wound up onto storage reel 56. A sorting card bearing the same data as that impressed on the stored strap is prepared by attaching a strip of magnetic tape from reel 57 to a web of card stock 58 cutting into individual card blanks at 59 and impressing the data magnetically on the tape by printer 60. The data so recorded is checked with that recorded on the strap and if correspondance is found the card is issued at 63. Each sorting card is loaded into the feeder at the bottom of the batch to which it relates until the magazine of the feeder holds, e.g. 1000 notes, i.e. 10 batches. The notes and sorting cards are then fed sequentially to belt conveyer 3. Sorting device.-Notes and sorting cards leaving the detector 5 are segregated at 6 into fit notes and unfit notes plus sorting cards. The fit notes are further sorted at 11 into soiled and normal notes. The normal notes are conveyed to collectors 12a and 12b where they are assembled in batches of 100. The soiled notes pass printer 16 (which cancels any notes which are too soiled to be used again) and are conveyed to collectors 14a and 14b where they are assembled in batches of 100. Completed batches are discharged from the collectors onto conveyer 17 and are routed by turning conveyer 18 to a jogging device 20, a device 21 for restrapping the batches, a strap checking device 24 and a printer 25 which marks the strap with data showing whether the batch contains soiled or normal notes. The batches are sorted at 26 into a normal rate batch collector and a soiled note batch collector. Counting device.-The unfit notes and their corresponding sorting cards are received in a collector 29. As each sorting card passes a recorder 27 it is impressed with the result obtained by subtracting the total number of normal and soiled notes received in collectors 12 and 14 from the number of notes in the original batch. This result should correspond to the number of unfit notes received in collector 29. To verify this the sorting card and corresponding unfit notes are manually fed into a count collator 48, Fig. 12, where the data on the sorting card is read by device 103 and compared with a count of the number of notes made by counters 104 and 107. The sorting cards are finally deposited in stacker 106 and the unfit notes in stacker 109. Separating paper fed from a roll 110 and cut by cutter 111 is used to segregate batches of 100 unfit notes. Fault detection.-If the passage of a note between two detectors takes longer than a prescribed time, a jamming display is activated and the conveyers stopped. If notes are too closely spaced a succeeding note is diverted temporarily into conveying path 8 until the preceding note has progressed further whereupon the succeeding note is reintroduced into the main conveying path.
