Description:
BACKGROUND OF THE INVENTION  
         [0001]    1. Technical Field  
           [0002]    The field of this invention relates to high-volume currency processing using currency processing machines.  
           [0003]    2. Description of the Related Art  
           [0004]    Automated, high-volume currency processing is a growing international industry affecting numerous aspects of the distribution, collection, and accounting of paper currency. Currency processing presents unique labor task issues that are intertwined with security considerations. Currency processing requires numerous individual tasks, for example: the collection of single notes by a cashier or bank teller, the accounting of individual commercial deposits or bank teller pay-in accounts, the assimilation and shipment of individual deposits or accounts to a central processing facility, the handling and accounting of a currency shipment after it arrives at a processing facility, and the processing of individual accounts through automated processing machines. Any step in the process that can be automated, thereby eliminating the need for a human labor task, saves both the labor requirements for processing currency and increases the security of the entire process. Security is increased when instituting automated processes by eliminating opportunities for theft, inadvertent loss, or mishandling of currency and increasing accounting accuracy.  
           [0005]    A highly automated, high-volume processing system is essential to numerous levels of currency distribution and collection networks. Several designs of high-volume processing machines are available in the prior art and used by such varied interests as national central banks, independent currency transporting companies, currency printing facilities, and individual banks. In general, currency processing machines utilize a conveyer system which transports individual notes past a series of detectors. By way of example, a note may be passed through a series of electrical transducers designed to measure the note&#39;s width, length, and thickness. The next set of sensors could be optical sensors recording the note&#39;s color patterns. Detectors can likewise be used to detect specific magnetic or other physical characteristics of individual notes.  
           [0006]    High volume currency processing machines typically pull individual notes from a stack of currency through a mechanical conveyer past several different detectors in order to facilitate the sorting of the individual notes and the accumulation of data regarding each note fed through the machine. For example, a currency processing machine can perform the simple tasks of processing a stack of currency in order to ensure that it is all of one denomination with proper fitness characteristics while simultaneously counting the stack to confirm a previous accounting. A slightly more complex task of separating a stack of currency into individual denominations while simultaneously counting the currency can be accomplished as well. On the more complex end of prior art currency processing machines, a stack of currency consisting of various denominations can be fed into the machine for a processing that results in the separation of each denomination, a rejection of any currency that does not meet fitness specifications, the identification of counterfeit bills, and the tracking of individual notes by serial number.  
           [0007]    Older prior art high-volume currency processing machines are loaded with one single stack of currency, identified to a single set of accounting parameters, before executing the sort process. For example, a stack of currency associated with a specific commercial deposit at a bank may be loaded at the beginning of the currency processing cycle. The currency is then fed into the currency processing machine and sorted based on the needs of the customer. Data obtained from the sort process, for example the number of each denomination note that was detected during the procedure and the total deposit amount, is then compared to the same data identified to the stack of currency prior to the processing cycle. However, a newer prior art currency processing methods have become available that reduces the labor involved in loading the currency processing machine and improves the security involved in this step. Specifically, these currency processing methods process numerous stacks of currency identified to individual accounting parameters one after another without having to wait to reload or stop the machine in order review data collected on each individual account.  
           [0008]    However, in addition to sorting numerous stacks of currency to individual accounting parameters, a need exists to process change orders as well. A change order is an order for a certain number of various denominations of currency needed by a bank customer. For example, a store may send an order for twenty-five $1.00 notes, fifty $5.00 notes, fifty $10.00 notes, and one hundred $20.00 notes. These represent the currency denominations and amounts the store needs to conduct operations for the day. However, each customer has different requirements and, furthermore, each customer&#39;s requirements may change from day to day. Therefore, a predetermined routine for filling change orders cannot be used. Because the requirements for different customers are different and because requirements change from day to day, prior art currency processing machines are incapable of filling these change orders which resulted in the change orders being filled manually. Therefore, a need exists for an improved currency processing machine and methods capable of filling change orders automatically with minimal use of manual labor.  
         SUMMARY OF THE INVENTION  
         [0009]    The present invention provides a currency processing machine and method, system, and computer program product for filling change orders. In one embodiment, the currency processing machine includes a document input which receives a stack of documents and feeds single documents from the stack of documents into the document processing machine. The currency processing machine also includes an information collection system collects identifying information about the documents, sorting bins for receiving the documents, a sorter; and a data processing system. The data processing system receives information regarding the quantity of each of several denominations needed by a customer for a change order and dynamically dedicates at least one of the sorting bins for use for filling the change order. The data processing system instructs the sorter to deliver specified quantities of notes of specified denominations to the sorting bins designated for use for filling the change order.

     DETAILED DESCRIPTION  
       [0019]    [0019]FIG. 1 shows a currency processing machine  10  embodying the present invention and loaded with a batch feed of currency  12  prior to starting the currency processing cycle. This batch feed of currency  12  is fed into the currency processing machine one single note at a time. Single notes then travel on a conveyer past several different detectors before being deposited in one of the sort bins  14 . Typically, a single sort bin is used to accumulate a single denomination of note at the end of the sort process.  
         [0020]    [0020]FIG. 2 shows a currency batch  12  having several individual currency stacks. The currency batch  12  illustrated consists of a first stack of currency  16 , a second stack of currency  20 , and a third stack of currency  24 . Each stack of currency is accompanied with a separator card  18 ,  22 ,  26 . In this embodiment, the separator cards  18 ,  22 ,  26  are shown as header cards where a first separator card  18  is stacked on top of the first stack of currency  16  and would identify the first stack of currency  16  during the currency processing cycle. Likewise, a second separator card  22  is stacked on top of a second stack of currency  20  and identifies the second stack of currency during the currency processing cycle. It is understood that the present invention contemplates that numerous currency stacks  16 ,  20 ,  24  such as the three depicted can be successively stacked to form a large batch feed  12  prior to insertion in the currency processing machine  10 . It is also understood that an alternative embodiment from that depicted in FIG. 2 could use separator cards  18 ,  22 ,  26  at the end of each stack of currency  16 ,  20 ,  24 , called trailer cards. A third embodiment could use both header cards and trailer cards to separate the currency stacks  16 ,  20 ,  24 .  
         [0021]    [0021]FIGS. 3A and 3B depict an exemplar separator card  18  of the present invention. FIG. 3A shows the first side  28  of the separator card  18 , while FIG. 3B shows the second side  30  of the separator card  18 . In the embodiment shown by FIGS. 3A and 3B, the first side  28  is overlaid with a first magnetic strip  32  and a second magnetic strip  34 . The second side  30  is imprinted with a bar code  36 . As will be described in more detail below, this embodiment allows for accurate identification of a separator card  18  primarily by detection of the two magnetic strips  32 ,  34 , while accounting data on an individual stack of currency can be identified to a specific bar code number encoded on the bar code  36  of the separator card  18 .  
         [0022]    [0022]FIG. 4 shows a flow chart of a method of processing currency utilizing separator cards and simultaneously filling change orders for bank customers. Using the same exemplar batch of currency  12  shown in FIG. 2, FIG. 4 shows three individual currency stacks  16 ,  20 ,  24 . Account data  56 ,  58 ,  60  associated with each currency stack  16 ,  20 ,  24  is first recorded for each account. This account data  56 ,  58 ,  60  might include the number of individual currency notes, the total currency value, and the identity of the currency stack to a single commercial deposit or bank teller&#39;s shift. The account data  56 ,  58 ,  60  is then associated with a separator card  18 ,  22 ,  26 , which will accompany an individual currency stack  16 ,  20 ,  24 . This account data can be identified to a separator card by either identifying a bar code number unique to the specific separator card to the account data or by encoding the account data information directly on to the separator card. The physical combination of separator cards  18 ,  22 ,  26  and the currency stacks  16 ,  20 ,  24  form what is shown as single accounting subsets  68 ,  70 ,  72 . These accounting subsets  68 ,  70 ,  72  can then be stacked into a currency batch  12 . This currency batch  12  is fed into a currency processing machine  10 .  
         [0023]    During the currency processing cycle individual notes from each accounting subset  68 ,  70 ,  72  are sorted into sort bins  82 ,  84 ,  86 ,  88 ,  90 ,  92 ,  100 ,  102 ,  104 . Typically, these sort bins are used to bundle individual denomination notes. For example, the first sort bin  82  may be designated to accumulate $1.00 notes, while the second sort bin  84  may be designated to accumulate $5.00 notes. FIG. 4 shows a separate bin  94  for a rejected sort with the separator cards. This rejected sort bin  94  could be designated to hold any counterfeit currency detected during the currency sort process. By depositing the counterfeit currency with the separator cards  18 ,  22 ,  26 , a quick physical check can be made to determine which single accounting subset  68 ,  70 ,  72  is associated with the counterfeit notes found to follow a specific separator card  18 ,  22 ,  26 .  
         [0024]    Additionally, during the currency processing cycle, change orders for various customer&#39;s are filled by dedicating a certain sorting bins  100 ,  102 ,  104  to individual customers having change orders to be filled. Change order information  98  is received from the bank&#39;s customers and sent to the currency processing machine  10 . After a currency note has been processed for account information, the currency note is sorted into one of bins  100 ,  102 ,  104  to fill a customer&#39;s change order requirement. While bin  100  is receiving notes of a first denomination value (e.g., $1.00 notes) as notes of that denomination become available, bin  102  is receiving notes of a second denomination value (e.g., $5.00 notes) and bin  104  is receiving notes of a third denomination value (e.g., $10.00 notes) as notes of the second and third denomination values become available. Notes not needed by any of the change order bins  100 ,  102 ,  104  are routed to one of sorting bins  82 ,  84 ,  86 ,  88 ,  90 ,  92 . Once each change order bin  100 ,  102 ,  104  has had its order filled for a current denomination value, the next value of denomination needed to fill the change order for the current customer assigned to a change order bin  100 ,  102 ,  104 .  
         [0025]    Once a change order is complete, an operator may stop the currency processing machine  10  to remove the change order notes. The operator then resumes operation the currency processing machine  10  and the next change order or orders received by change order information  98  is processed. Once all of the account deposits have been processed, a determination of the remaining quantities of denominations needed to complete change orders currently being processed and to complete change orders yet to be processed is made. An operator then retrieves the needed quantities and places them into the input of the currency processing machine  10  and change order filling continues. Other sort bins  82 ,  84 ,  86 ,  88 ,  90 ,  92  used for other purposes during account deposit processing may now be used as additional change order bins allowing more change orders to be processed simultaneously.  
         [0026]    Returning now to account deposit processing, account data  96  for each accounting subset  68 ,  70 ,  72  is accumulated during the currency processing cycle. This account data  96  can then be compared with similar account data  56 ,  58 ,  60  which was originally collected for each individual currency stack  16 ,  20 ,  24 . For example, while processing the first accounting subset  68 , the currency processing machine can accumulate information on the number of each denomination of note processed and the total currency value of the notes associated with the first accounting subset  68 . This account data  96  accumulated on the first accounting subset  68  can then be compared to the account data  56  associated with the first currency stack  16  prior to the consolidation of the accounting subset  68   70 ,  72  into the currency batch  12 .  
         [0027]    [0027]FIG. 5 shows a flow chart of a method for identifying separator cards used by currency processing machines and a method for filling change orders for bank customers. FIG. 5 starts with the single accounting subset  68 ,  70 ,  72 , that are likewise shown on FIG. 4. These accounting subsets  68 ,  70 ,  72  are stacked to form a currency batch  12 . This currency batch is then loaded into the currency processing machine  98 . The top item off of the currency batch  12 , whether it is a separator card  80  or currency  100 , is then pulled into a conveyer past several detectors.  
         [0028]    The first detector shown in FIG. 5 is a magnetic field detector  102 . This magnetic field detector can detect a unique magnetic strip on a separator card  80  in order to assist the currency processing machine in delineating between separator cards  80  and currency  100 . This can be accomplished even in the event of a misfeed which results in a currency note  100  masking other physical features of the separator card  80 , since the magnetic field of the separator card  80  can be read through the masking currency  100 . The currency processing machine can be designed to read the individual serial number on the note masking what it detects to be a concurrently stacked separator card  80 . The information obtained by the magnetic field detector on the separator card, as well as information obtained on the masking note throughout the following detectors, allows for a reconstruction of the misfeed and avoids co-mingling of the accounting subsets  68 ,  70 ,  72  during the currency processing cycle.  
         [0029]    The next detector depicted in FIG. 5 is a bar code reader  104 . This bar code reader identifies the specific bar code number for each individual separator card  80  read. The bar code number is then identified by the currency processing machine with the currency  100  that follows the specific separator card  80 . The separator card  80  or currency  100  then passes through one or more detectors designed to measure the thickness and size of the item on the conveyer, as depicted in FIG. 5 by a thickness detector  106  and a size detector  108 . This information can be of additional use to the currency processing machine in distinguishing between a separator card  80  and currency  100 . The final detector shown on FIG. 5 is an optical pattern detector  110 . This optical pattern detector  110  can likewise assist in the process of delineating between a separator card  80  and currency  100 , both having unique color characteristics and patterns.  
         [0030]    It is understood that the order and type of detectors shown in FIG. 5 represent only one example of a preferred embodiment for the method described. The detectors used in the present invention could be arranged in many different sequences. In addition, other types of detectors can be used to record various characteristics of currency and separator cards.  
         [0031]    After passing through the currency processing machine, the currency  100  is deposited in the appropriate sort bin  82 ,  84 ,  86 ,  88 ,  90 ,  92  as a part of the currency sort process or in change order bins  100 ,  102 ,  104  as part of the change order filling process in response to the change order information  98  received from customers. The separator card, likewise is directed to the separator card sort bin  94 .  
         [0032]    Account data  96  collected by the currency processing machine on each accounting subset  68 ,  70 ,  72  can be compared to similar account data that was associated with the accounting subset  68 ,  70 ,  72  prior to the consolidation of these accounts into the currency batch  12 . As shown in FIG. 5, the account data  96  collected during the currency processing cycle is assimilated from information provided by the various detectors  102 ,  104 ,  106 ,  108 ,  110 .  
         [0033]    The preferred embodiment illustrated in FIG. 5 can additionally detect sequencing errors between separator cards  80  and currency notes  100 . For example, when the accounting subsets  68 ,  70 ,  72  are comprised of currency stacks separated by header cards, the first item processed through the sequence shown in FIG. 5 should be a separator card  80 . The next item processed should be currency  100 . If a separator card  80  is detected immediately following the processing of another separator card  80 , this event would be identified as a sequencing error which might be traced to improper stacking of the accounting subsets  68 ,  70 ,  72 . Sequencing errors could likewise be detected when the separator card  80  is a trailer card. The most accurate detection of sequencing errors, however, occurs when the preferred embodiment utilizes both header and trailer cards with each accounting subset  68 ,  70 ,  72 . The use of both header and trailer cards requires, in sequence, that the first separator card  80  processed for an accounting subset  68 ,  70 ,  72  is a header card. The next item processed should be currency  100 . The next separator card  80  detected should be a trailer card. A trailer card would then be immediately followed by a header card for the next accounting subset. Any deviations from the above described sequence would, again, indicate a sequencing error that might be attributable to improper stacking of separator cards  80  and currency  100  in the accounting subsets  68 ,  70 ,  72 .  
         [0034]    [0034]FIG. 6 shows a flowchart showing logical steps for processing account deposit information and also fulfilling change order requirements for various customers. Notes and separators are placed in input bin  12  of currency processing machine  10  (step  602 ). Each note and separator card is recognized and authenticated by the currency processing machine  10  (step  604 ) and the input reconciled against respective accounts (step  606 ). Output batching requirements for change orders are received from customers (step  608 ) and provided to the currency processing machine  10  which uses the information to transport notes to dynamically allocated pockets and, in some embodiments, fixed denomination pockets, such that change orders for the customers are fulfilled (step  610 ). Shortfalls in output change order batches are displayed to an operator and corrective action is taken either manually by the operator or automatically by the currency processing machine  10  (step  612 ). Once change orders are filled, an operator collects the output batches for the change orders from the output bins  14  of the currency processing machine  10  as well as collects the excess sorted or unsorted notes.  
         [0035]    With reference now to FIG. 7, a block diagram of a data processing system is shown in which the present invention may be implemented. Data processing system  200  is an example of a computer which may be implemented within a currency processing machine such as currency processing machine  10 , in which code or instructions implementing the processes of the present invention may be located. Data processing system  200  employs a peripheral component interconnect (PCI) local bus architecture. Although the depicted example employs a PCI bus, other bus architectures such as Accelerated Graphics Port (AGP) and Industry Standard Architecture (ISA) may be used. Processor  202  and main memory  204  are connected to PCI local bus  206  through PCI bridge  208 . PCI bridge  208  also may include an integrated memory controller and cache memory for processor  202 . Additional connections to PCI local bus  206  may be made through direct component interconnection or through add-in boards. In the depicted example, local area network (LAN) adapter  210 , small computer system interface SCSI host bus adapter  212 , and expansion bus interface  214  are connected to PCI local bus  206  by direct component connection. In contrast, audio adapter  216 , graphics adapter  218 , and audio/video adapter  219  are connected to PCI local bus  206  by add-in boards inserted into expansion slots. Expansion bus interface  214  provides a connection for a keyboard and mouse adapter  220 , modem  222 , and additional memory  224 . SCSI host bus adapter  212  provides a connection for hard disk drive  226 , tape drive  228 , and CD-ROM drive  230 . Typical PCI local bus implementations will support three or four PCI expansion slots or add-in connectors.  
         [0036]    An operating system runs on processor  202  and is used to coordinate and provide control of various components within data processing system  200  in FIG. 2. The operating system may be a commercially available operating system such as Windows XP, which is available from Microsoft Corporation. An object oriented programming system such as Java may run in conjunction with the operating system and provides calls to the operating system from Java programs or applications executing on data processing system  200 . “Java” is a trademark of Sun Microsystems, Inc. Instructions for the operating system, the object-oriented programming system, and applications or programs are located on storage devices, such as hard disk drive  226 , and may be loaded into main memory  204  for execution by processor  202 .  
         [0037]    Those of ordinary skill in the art will appreciate that the hardware in FIG. 2 may vary depending on the implementation. Other internal hardware or peripheral devices, such as flash read-only memory (ROM), equivalent nonvolatile memory, or optical disk drives and the like, may be used in addition to or in place of the hardware depicted in FIG. 2. Also, the processes of the present invention may be applied to a multiprocessor data processing system.  
         [0038]    For example, data processing system  200 , if optionally configured as a network computer, may not include SCSI host bus adapter  212 , hard disk drive  226 , tape drive  228 , and CD-ROM  230 . In that case, the computer, to be properly called a client computer, includes some type of network communication interface, such as LAN adapter  210 , modem  222 , or the like. As another example, data processing system  200  may be a stand-alone system configured to be bootable without relying on some type of network communication interface, whether or not data processing system  200  comprises some type of network communication interface. As a further example, data processing system  200  may be a personal digital assistant (PDA), which is configured with ROM and/or flash ROM to provide non-volatile memory for storing operating system files and/or user-generated data.  
         [0039]    The depicted example in FIG. 2 and above-described examples are not meant to imply architectural limitations.  
         [0040]    The processes of the present invention are performed by processor  202  using computer implemented instructions, which may be located in a memory such as, for example, main memory  204 , memory  224 , or in one or more peripheral devices  226 - 230 .  
         [0041]    It would be understood that various changes in the details, materials, and arrangements, of the processes which have been described and illustrated in order to explain the nature of the invention, may be made by those skilled in the art within the principle and scope of the invention as expressed in the following claims. For example, the number of sorting bins utilized may be more or less than those depicted in the various examples presented. Furthermore, a larger or smaller percentage of the sorting bins may be dedicated for use in filling change orders than has been depicted herein.  
         [0042]    Furthermore, it is important to note that while the present invention has been described in the context of a fully functioning data processing system, those of ordinary skill in the art will appreciate that the processes of the present invention are capable of being distributed in a form of a computer readable medium of instructions and in a variety of forms. Further, the present invention applies equally regardless of the particular type of signal bearing media actually used to carry out the distribution. Examples of computer readable media include recordable-type media such a floppy disc, a hard disk drive, a RAM, a CD-ROM, a DVD-ROM, and transmission-type media such as digital and analog communications links, wired or wireless communications links using transmission forms such as, for example, radio frequency and light wave transmissions. The computer readable media may take the form coded formats that are decoded for actual use in a particular data processing system.  
         [0043]    The description of the present invention has been presented for purposes of illustration and description, but is not limited to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention the practical application to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated
