Title: Currency transport mechanism

Description:
CROSS-REFERENCE TO RELATED PATENT APPLICATIONS 
     The present application claims priority to U.S. Provisional Application No. 61/935,252, titled “Currency Transport Mechanism” filed Feb. 3, 2014, the entirety of which is herein incorporated by reference. 
    
    
     BACKGROUND 
     The present invention relates generally to devices that accept paper currency. Such devices include automated teller machines (“ATMs”), bank teller bill recyclers, vending machines, or any other device configured to accept paper currency. In some cases, such devices may recycle received paper currency. The term “recycling” as used herein refers to receiving paper currency in a first transaction and later dispensing the previously received currency in a second transaction. In other cases, instead of recycling received currency, such devices may deposit and hold received paper currency in a first currency storage cassette and dispense currency from a second currency storage cassette. The second currency storage cassette is typically preloaded in the device by the operator of the device (e.g., a bank). For example, a first user may deposit a currency bill at an ATM. The deposited currency bill is stacked in a first bill cassette in the ATM. Subsequently, a second user may request a cash withdrawal from the same ATM. The ATM completes the cash withdrawal by dispensing an appropriate amount of paper currency from a second cassette that was preloaded with paper currency by the owner of the ATM. 
     Utilization of currency recycling mechanisms in ATMs and other devices has been limited because not all received currency is appropriate for recycling. Some paper currency includes rips, tears, creases, and other defects that may cause jams within the device during dispensing operations. Accordingly, the owners and operators of the dispensing devices often preload the devices with currency that is deemed “fit” for dispensing. Fit currency is currency that is relatively free of rips, tears, creases, and other defects such that the risk of a jam occurring during a dispensing operation is greatly reduced. The fit currency is dispensed during withdrawal operations. 
     SUMMARY 
     A first exemplary embodiment relates to a currency receiving and dispensing device. The device includes a bill input configured to receive paper currency bills. The device further includes a cassette configured to store received paper currency bills. The device includes a transport mechanism coupled to the bill input and the cassette, the transport mechanism is configured to transport received paper currency bills from the bill input to the cassette. The device further includes a heating element coupled to the transport mechanism or the cassette, the heating element configured to heat the paper currency bills.

     DETAILED DESCRIPTION 
     Numerous specific details may be set forth below to provide a thorough understanding of concepts underlying the described implementations. It may be apparent, however, to one skilled in the art that the described implementations may be practiced without some or all of these specific details. In other instances, some process steps have not been described in detail in order to avoid unnecessarily obscuring the underlying concept. 
     The following systems and methods relate to devices that recycle received paper currency by dispensing the received paper currency in later transactions. The described systems include mechanisms to condition received paper currency such that the received paper currency becomes fit for recycling. The conditioning may be achieved by heating the received paper currency, steaming the received paper currency, exposing the received paper to pressure, or a combination thereof. 
     Referring to  FIG. 1 , a perspective view of an ATM  100  is shown according to an exemplary embodiment. The ATM includes a display  102 , a keypad  104 , and a card reader  106 . ATM  100  is configured to provide a user paper currency during a withdrawal transaction through a paper currency output  108 . ATM  100  may be configured to provide multiple denominations of paper currency during the withdrawal transaction. Additionally, ATM  100  is configured to receive paper currency from a user during a deposit transaction through a deposit input ( 110 ). ATM  100  may be configured to receive multiple denominations of paper currency during the deposit transaction. ATM  100  includes a printer  112  configured to print receipts of transactions and other records (e.g., bank account statements). During operation, ATM  100  may recycle received paper currency by providing paper currency during a withdrawal transaction that was received in an earlier deposit transaction. ATM  100  is configured to condition received paper currency such that the received paper currency becomes fit for recycling thereby reducing the risk of jams occurring in the currency transport mechanisms within ATM  100 . The conditioning is achieved by heating the received paper currency, steaming the received paper currency, exposing the received paper currency to pressure, or a combination thereof as described in further detail below. 
     Referring to  FIG. 2 , a schematic diagram of a paper currency recycling system  200  is shown according to an exemplary embodiment. System  200  may be part of an ATM (e.g., ATM  100 ), a bank teller bill recycler, a vending machine, or another system configured to receive and output paper currency. The bolded arrows of  FIG. 2  represent the paths that paper currency may take within system  200 . System  200  is configured to receive paper currency through a bill input  202  and to output paper currency through a bill output  204 . In an alternative arrangement, the bill input and bill output may be a single device configured to perform both functions. After being received in the system  200  through the bill input  202 , paper currency passes through a sensor  206 . The sensor  206  may include a plurality of sensors. The sensor  206  is configured to detect characteristics of the received paper currency and provide feedback signals of the detected characteristics to a controller  208  of the system. The controller  208  is configured to validate the received paper currency as genuine based on analyzing the feedback relating to the detected characteristics received from sensor  206 . The detected characteristics may relate to properties of the received paper currency, such as physical properties of the paper currency (e.g., size, weight, conductivity, fluorescent properties, reflective properties, security feature locations, magnetic properties, etc.) and optical properties of the paper currency (e.g., what is printed on the paper currency, the color of the currency, printed security feature attributes, pixel spacing, etc.). The controller  208  may determine a denomination of the received paper currency based on the above recited characteristics. Additionally, the controller  208  may determine a condition of the received paper currency based on the feedback signal relating to detected characteristics of the received paper currency from the sensor  206 . The received paper currency may be rejected by the system  200  if the received paper currency is not genuine or if the condition of the received paper currency falls outside of an acceptable range (e.g., if the received paper currency is mutilated). 
     If the received paper currency is deemed to be genuine and if the condition of the currency is acceptable, a transportation  210  mechanism transports the received currency to one of the cassettes  212 . The transport mechanism  210  is coupled to at least one cassette  212 . In some arrangements, the system  200  includes a plurality of cassettes (e.g., one cassette for each denomination of accepted paper currency, a cassette for received paper currency that falls within the acceptable condition range but outside of a fit condition for recycling, a cassette that was preloaded with fit currency, etc.). In other arrangements, the system  200  may include a single cassette  212 . The transportation mechanism  210  may include rollers, belts, and grippers configured to transport paper currency between the bill input  202 , the bill output  204 , and the cassettes  212 . The transportation mechanism  210  is configured to transport received and accepted paper currency from the bill input  202  to a designated cassette  212  during deposit operations. The transportation mechanism  210  may also be configured to transport paper currency from a designated cassette  212  to the bill output  204  during withdrawal operations. In some arrangements, a second transportation mechanism is configured to transport paper currency from the cassettes  212  to the bill output  204  during withdrawal operations. The transport mechanism  210  may include a flipping mechanism such that received paper currency is stacked in the same direction within a given cassette  212 . 
     The transportation mechanism  210  is coupled to a paper currency conditioner  214 . The conditioner  214  selectively performs a conditioning operation on the received paper currency while the received paper currency is transported by transportation mechanism  210 . The conditioning operation increases a fit level of the received paper currency. By increasing the fit level of the received paper currency, the received paper currency may be transformed from currency that is not suitable for recycling (i.e., currency that is not capable of being dispensed in a later withdrawal operation) to currency that is suitable for recycling. The conditioning may be achieved at least in part by heating the received paper currency. Accordingly, the conditioner  214  may include a heating element. In some arrangements, the heating element directly heats the received paper currency (i.e., as the received paper currency passes through the transportation mechanism  210 , the paper currency passes through the heating element). In other arrangements, the heating element heats components of the transportation mechanism  210  (e.g., a roller or a conveyor), which in turn heat the received paper currency as the paper currency is routed through the transportation mechanism  210 . The components of the transportation mechanism  210  that are heated may be metal. In some arrangements, the heating element includes a heat transfer system (e.g., a heat pipe, a heat exchanger, etc.) configured to transport heat from a heat-generating component of the system  200 , such as controller  208 , to the received paper currency as described above. Heating the received paper currency may remove at least a portion of creases contained within the received paper currency thereby increasing the received paper currency&#39;s suitability for recycling. In some arrangements, the transportation mechanism  210  may be configured to exert pressure on the received paper currency during the conditioning operation (e.g., by passing the received currency through opposing rollers or belts). The pressure may also assist in conditioning the received paper currency and increasing the received paper currency&#39;s suitability for recycling. In additional arrangements, the conditioner  214  may include a steaming device configured to steam the received paper currency. 
     Alternatively or additionally, the conditioner  214  may be coupled to at least one of the cassettes  212 . Accordingly, received paper currency may be conditioned after the received paper currency is routed to the designated cassette  212 . In such an arrangement, a stack of received paper currency in the cassette  212  may be conditioned through heating, steaming, and/or pressure (e.g., the pressure already exerted on the stack of received paper currency by the stacking mechanism associated with the cassette  212 ). 
     Cassettes  212  are configured to receive and store paper currency. System  200  may include a single cassette  212  or a plurality of cassettes  212 . If the system  200  includes a plurality of cassettes  212 , each of the plurality of cassettes may be designated to hold a particular denomination of paper currency. The cassettes  212  may also configured to dispense paper currency during withdrawal operations. At least one cassette of the plurality of cassettes  212  may be configured to only store currency that is not fit for recycling. Each cassette includes a stacking mechanism configured to store paper currency in a stack. 
     Referring to  FIG. 3 , a method  300  of receiving and conditioning paper currency for recycling is shown according to an exemplary embodiment. Method  300  may be performed by a device configured to receive and dispense paper currency (e.g., ATM  100 , system  200 , etc.). Method  300  begins when paper currency is received ( 302 ). Paper currency is received via a paper currency input (e.g., deposit input  110 , bill input  202 , etc.). The paper currency is analyzed to determine whether it is authentic ( 304 ). The paper currency is passed through a sensor (e.g., sensor(s)  206 ). The sensor may include a plurality of sensors. The sensor is configured to detect characteristics of the received paper currency and provide feedback signals of the detected characteristics to a controller of the system. The controller is configured to validate the received paper currency as genuine based on analyzing the feedback relating to the detected characteristics received from sensor. The detected characteristics may relate to properties of the received paper currency, such as physical properties of the paper currency (e.g., size, weight, conductivity, fluorescent properties, reflective properties, security feature locations, magnetic properties, etc.) and optical properties of the paper currency (e.g., what is printed on the paper currency, the color of the currency, printed security feature attributes, pixel spacing, etc.). During the authentication process, the controller may additionally determine a denomination of the received paper currency based on the above recited characteristics. Based on the above-noted characteristics, the controller determines whether the received paper currency is authentic. 
     If the paper currency is deemed not authentic, then the paper currency is rejected ( 306 ). The received currency is rejected by outputting the received currency through the currency input or through a separate currency output. 
     If the paper currency is deemed authentic, then it is determined whether the paper currency is conditionable into fit currency ( 308 ). The controller of the system determines a condition of the received paper currency based on the above discussed feedback signal relating to detected characteristics of the received paper currency from the sensor. Some received paper currency may have a condition that is not suitable for conditioning into recyclable paper currency. For example, the received paper currency may include greater than a threshold number of defects, such as folds, wrinkles, creases, rips, tears, and other defects. Other currency may include less than a threshold number of defects such that the paper currency can be conditioned into fit currency for recycling. 
     If the paper currency is not conditionable into fit currency, the paper currency is deposited into a cassette that stores non-recyclable paper currency ( 310 ). The cassette is configured to receive and store the unfit paper currency. The cassette may include a stacking mechanism. The paper currency is transported to the cassette via a transportation mechanism. The transportation mechanism includes rollers, belts, and/or grippers configured to transport the paper currency between the currency input and the cassette. 
     If the paper currency is conditionable into fit currency, a conditioning operation is performed on the paper currency ( 312 ). The conditioning operation may be performed as the paper currency travels through the transportation mechanism. The conditioning operation increases a fit level of the received paper currency. By increasing the fit level of the received paper currency, the received paper currency may be transformed from currency that is not suitable for recycling (i.e., currency that is not capable of being dispensed in a later withdrawal operation) to currency that is suitable for recycling. The conditioning may be achieved at least in part by heating the received paper currency. Accordingly, a heating element applies heat to the received paper currency. In some arrangements, the heating element directly heats the received paper currency (i.e., as the received paper currency passes through the transportation mechanism, the paper currency passes through the heating element). In other arrangements, the heating element heats components of the transportation mechanism (e.g., a roller or a conveyor of the transportation mechanism), which in turn heat the received paper currency as the paper currency is routed through the transportation mechanism  210 . The components of the transportation mechanism that are heated may be metal. In some arrangements, the heating element includes a heat transfer system (e.g., a heat pipe, a heat exchanger, etc.) configured to transport heat from a heat-generating component, such as the controller of the system, to the received paper currency as described above. Heating the received paper currency may remove at least a portion of creases contained within the received paper currency thereby increasing the received paper currency&#39;s suitability for recycling. In some arrangements, the transportation mechanism may be configured to exert pressure on the received paper currency during the conditioning operation (e.g., by passing the received currency through opposing rollers or belts). The pressure may also assist in conditioning the received paper currency and increasing the received paper currency&#39;s suitability for recycling. In additional arrangements, the conditioning operation may include subjecting the received paper currency to steam from a steaming device. 
     The conditioned paper currency is deposited into a cassette that stores recyclable paper currency ( 314 ). After the conditioning operation, the conditioned paper currency is transported to a designated storage cassette by the transportation mechanism. The cassettes are configured to receive paper currency, store paper currency, and dispense paper currency. Each cassette may be designated to hold a particular denomination of paper currency. Each cassette includes a stacking mechanism configured to store paper currency in a stack. In some arrangements, the conditioning operation may take place after the received paper currency is deposited in the cassette. In such an arrangement, a stack of received paper currency in the cassette may be conditioned through heating, steaming, and/or pressure (e.g., the pressure already exerted on the stack of received paper currency by the stacking mechanism associated with the cassette). Conditioning of the received currency within the cassette may take place in addition to or instead of the above-noted conditioning that takes place during the currency&#39;s passage through the transportation mechanism. 
     A request to withdraw paper currency is received ( 316 ). The request may be received at the controller of the system. Paper currency from the cassette storing recyclable paper currency is dispensed ( 318 ). The controller instructs the appropriate cassette and the transportation mechanism to dispense the recyclable paper currency from the cassette. The transportation member transports the paper currency from the cassette and to a currency output of the system (e.g., cash output  108 , bill output  204 , etc.). In some arrangements, a second transportation mechanism is configured to output paper currency while a first transportation mechanism is configured to receive the paper currency. 
     Although described as being a component of an ATM, the above-described currency routing mechanisms and methods of routing currency may be employed with other devices that recycle paper currency. For example, the above described currency routing mechanism and method of routing currency may be employed with bank teller bill recyclers, vending machines, and the like.
