Description

Technical Field

[0001] The present invention relates to a paper processing device having a drive unit that can be replaced before failure, a gaming machine management device using the paper processing device, and a method for displaying a degree of degradation of the paper processing device. Background Art

[0002] The applicant of the present patent is the patentee of Japanese Patent No. 5484866 shown as Patent Document 1 in this specification, and has been producing and selling a paper sheet processing device based on the patent for many years, but the paper sheet processing device has the following disadvantages: in the event of a failure, the game machine itself in which the paper sheet processing device is built cannot be operated until the repair is completed, and the profit generated by the operation of the game machine cannot be obtained. The main cause of the failure of the paper sheet processing device is the deterioration caused by the operation of the drive unit constituting the operation part of the paper sheet processing device, and has the following disadvantages: once the drive unit fails, the game machine using the paper sheet processing device cannot be operated until the drive unit is replaced. The paper sheet processing device disclosed in Patent Document 1 has the advantages that the drive unit, the identification device and the storage device are constituted as separate units, and each unit can be easily separated, disassembled, assembled, maintained, inspected and replaced, and has the advantages that the integrated drive unit that can be detached and assembled can be removed from the paper sheet processing device, and the drive unit can be easily replaced and maintained and inspected.

[0003] Patent document 2 shows an automatic banknote deposit and withdrawal device, in which a memory (storage device) for storing the type of the box is respectively set in the temporary holding box and the replenishment / recovery box, and the control unit receives information from each memory via a connector, and the control unit identifies the type of the box based on the memory information.

[0007] Patent Document 2: Japanese Patent Application Laid-Open No. 10-27274 Summary of the invention

[0008] Problems to be solved by the invention

[0009] When the drive unit of the paper sheet processing device disclosed in Patent Document 1 is used continuously, its deterioration state cannot be identified and the time when the failure or problem occurs cannot be predicted. Usually, a sudden failure or problem of the drive unit will cause the paper sheet processing device itself to fail to work or to work abnormally. If the drive unit fails, the paper sheet processing device and the game machine equipped with the paper sheet processing device cannot be operated until the drive unit is replaced with a normally working one. The paper sheet processing device and the game machine cannot be used, which has the disadvantage that the increase in revenue generated by the operation of the game machine cannot be expected, and the non-operation time of the paper sheet processing device and the game machine cannot be reduced.

[0010] Therefore, an object of the present invention is to provide a paper processing device capable of identifying the degree of degradation or replacement time of a drive unit to be replaced, a gaming machine management device using the paper processing device, and a method for displaying the degree of degradation of the paper processing device.

[0011] Solutions to Solve Problems

[0012] The paper sheet processing device (1) of the present invention comprises: an identification device (2) for identifying the authenticity of paper sheets; an identification conveying path (10) formed in the identification device (2); and a drive unit (13) detachably installed in the identification device (2). The components of the drive unit (13) that conveys paper sheets in the identification device (2) along the identification conveying path (10) are destined to deteriorate in stages or gradually due to the operation of the drive unit (13), thereby reducing the quality, performance or function. Therefore, the drive unit (13) comprises: one or more drive sensors (24) that detect physical values ​​related to the quality, performance or function of the drive unit (13); and a physical property storage device (25) that stores the physical values ​​detected by the drive sensor (24). The change in the physical quantity from the drive sensor (24) represents the degree of deterioration of the drive unit (13). By retrieving, taking out, and displaying the physical values ​​stored in the physical property storage device (25) all the time, periodically, or when necessary, it is possible to objectively grasp the degree of deterioration related to the quality, performance or function of the drive unit (13).

[0021] based on Figure 1 to Figure 7 The paper sheet processing device, the gaming machine management device, and the degradation degree display method of the paper sheet processing device of the present invention are described in detail. The terms "paper sheets" and "paper sheets" used in this specification should be broadly understood to include all valuable paper sheets such as banknotes, paper or resin currency, coupons, paper money, securities, vouchers, etc.

[0022] Basic structure of the present invention

[0023] The paper sheet processing device (1) involved in the embodiment of the present invention is a device obtained by improving the mechanical structure and electrical structure of the driving unit (13) of the conventional paper sheet processing device shown in Patent Document 1. The mechanical structure and electrical structure of the driving unit (13) used in the paper sheet processing device of the present invention are different from those of Patent Document 1, but the identification device (2), the identification conveying path (10) and the storage device (3) other than the driving unit (13) have the same structure and function as those of Patent Document 1. The driving unit (13) of the present invention includes: a driving sensor (24) for detecting a physical value related to the time-dependent change or degradation of the quality, performance or function of the driving unit (13); and a physical property storage device (25) for sorting and storing the physical value detected by the driving sensor (24), so that the state of the time-dependent change or degradation related to the quality, performance or function of the driving unit (13) can be objectively grasped. The embodiment of the present invention described in this specification can use the structure of the conventional identification device and storage device shown in Patent Document 1 except for the driving unit (13), and the content of Patent Document 1 can be directly applied to this specification.

[0024] Figure 1The paper sheet processing device (1) shown in the figure comprises: an identification device (2) for identifying the authenticity of paper sheets such as banknotes and coupons; an identification conveying path (10) formed in the identification device (2); and a driving unit (13) for conveying paper sheets in the identification device (2) along the identification conveying path (10). The driving unit (13) comprises: an identification conveying device (5) for conveying paper sheets inserted into the identification device (2) along the identification conveying path (10); and a storage conveying device (6) for storing paper sheets conveyed along the identification conveying path (10) by the identification conveying device (5) in the storage device (3). The driving unit (13) has a bottom surface covering the driving unit (13). Figure 2 The bottom cover (13a) is shown.

[0025] Figure 1 The identification device (2) shown in the figure comprises: an identification sensor (11) for generating a detection signal representing the optical characteristics of a paper sheet conveyed in an identification conveying path (10) by a driving unit (13); and a determination device (12) for receiving the detection signal from the identification sensor (11) and determining the authenticity of the paper sheet. Figure 6 ). The identification sensor (11) that generates a detection signal for forming an optical image of a paper sheet is, for example, composed of a contact image sensor (CIS) that acquires optical image data of a paper sheet moving along the identification conveying path (10). The paper sheet that is judged to be authentic by comparing the optical image data acquired by the identification sensor (11) with the optical image data of a regular paper sheet by the determination device (12) is transported to the storage device (3) via the identification conveying path (10) by the driving belt (36) of the identification conveying device (5), and is transported to the waiting room (61a) of the storage room (79) by the storage conveying device (6), and is stored in the storage room (79) from the waiting room (61a) by the pushing device (62). When the storage room (79) is full of paper sheets, the facility manager separates the full storage device (3) from the paper sheet processing device (1) and recovers the paper sheets in the storage room (79).

[0026] exist Figure 3The driving unit (13) of the mechanical structure shown in the figure comprises: a conveying motor (701) constituting the identification conveying device (5) for conveying the paper sheet inserted into the identification device (2) along the identification conveying path (10); and a pushing motor (702) constituting the storage conveying device (6) for pushing the paper sheet conveyed to the storage device (3) into the storage chamber (79) of the storage device (3). For the specific structure and function of the identification conveying device (5) and the storage conveying device (6) that convey the paper sheet through the conveying motor (701) and the pushing motor (702) respectively via the power transmission device (8) and push it into the storage device (3), refer to Patent Document 1. In an embodiment of the present invention, there is a fundamental difference from the structure of Patent Document 1 in the following aspects: various physical values ​​related to the quality, performance or function of the identification conveying device (5) including the conveying motor (701) and the power transmission device (8) are detected by multiple conveying sensors (241-246), and a conveying log is generated by digitizing, scoring or grading the detected physical values.

[0027] The identification conveying device (5) comprises: a reversibly driven conveying motor (701) capable of forward and reverse rotation; a pinion (not shown) fixed to the driving shaft of the conveying motor (701); a power transmission device (8) drivingly connected to the pinion; and a drive belt (36) operating via the pinion of the conveying motor (701) and the power transmission device (8). Different from the structure of the identification conveying device of Patent Document 1, the drive belt (36) comprises: a front drive belt (361) that rotates the entrance roller (46) at the front center of the identification conveying path (10) to convey the paper sheet; and a pair of rear drive belts (362) that convey the paper sheet at the rear of the identification conveying path (10). The front drive belt (361) and the rear drive belt (362) are driven by the conveying motor (701) via the power transmission device (8). The entrance roller (46) can also be rotated via a gear meshing with a gear rotated by the front drive belt (361).

[0028] Similar to the structure of Patent Document 1, a paper sheet processing device (1) includes a storage device (3) for storing paper sheets transported along a distinguishing transport path (10), and a drive unit (13) includes a storage conveying device (6) for storing paper sheets in a storage chamber (79) of the storage device (3). In an embodiment of the present invention, there is a fundamental difference from the structure of Patent Document 1 in the following aspects: various physical values ​​related to the quality, performance or function of the storage conveying device (6) including a push motor (702) and a power transmission device (8) are detected by a plurality of storage sensors (251-256), and a storage log is generated in which the detected physical values ​​are digitized, scored or graded.

[0029] Figure 6The electrical structure of the drive unit (13) used in the present invention is shown. The conventional drive unit shown in Patent Document 1 certainly does not have the electrical structure of the drive unit (13) used in the present invention. The identification conveying device (5) has a timing encoder (45) which measures the rotation time of the conveying motor (701) and generates a conveying measurement signal by rotating the front drive belt (361) that rotates the entrance roller (46). The timing encoder (45) that measures the rotation time of the conveying motor (701) can measure the rotation speed and number of rotations of the conveying motor (701). The entrance roller (46) that rotates through a gear (not shown) that is rotated by the front drive belt (361) or rotates in conjunction with the front drive belt (361) conveys the paper sheet inserted into the entrance (14) of the identification conveying path (10) along the identification conveying path (10).

[0030] In this way, the timing encoder (45) and the entrance roller (46) are driven by the front drive belt (361). The physical property storage device (25) also connected to the timing encoder (45) stores the drive log from the plurality of conveying sensors (241-246) together with the workload time of the drive unit (13) measured by the timing encoder (45). There is a fundamental difference from the structure of Patent Document 1 in the following aspects: the plurality of conveying sensors (241-246) detect various physical values ​​related to the quality, performance or function of the identification conveying device (5) including the conveying motor (701) and the power transmission device (8), and a storage log is generated by digitizing, scoring or grading the physical values ​​detected by the conveying sensors (241-246) and storing it in the physical property storage device (25).

[0031] Electrical structure of the drive unit

[0032] like Figure 6 As shown, various drive sensors (24), identification sensors (11) and timing encoders (45) for measuring various physical quantities of the conveying motor (701) and the pushing motor (702) are all connected to the physical property storage device (25). The physical quantities detected by each drive sensor (24) are sorted by the physical property storage device (25), and each physical quantity is stored in a required storage area together with the time signal measured by the timing encoder (45). In addition, the optical image signal of the paper sheet obtained by the identification sensor (11) is sent to the determination device (12), and the determination device (12) determines the authenticity of the paper sheet. The paper sheet judged as authentic by the determination device (12) based on the optical image signal is transported to the storage chamber (79) through the identification conveying device (5) and the storage conveying device (6).

[0033] When the optical image signal of the paper sheet is insufficient, the determination device (12) reverses the identification conveying device (5) to return the paper sheet to the entrance side along the identification conveying path (10), and rotates the identification conveying device (5) forward again to convey the paper sheet along the identification sensor (11), so that the physical property storage device (25) counts the number of times the paper sheet identification is performed again. The paper sheet processing device (1) or the drive unit (13) is connected to the terminal retrieval device (401) of the central management device (300) via a connection device (25a) such as a USB interface, and the physical quantity stored in the physical property storage device (25) is read out by the terminal retrieval device (401). The central management device (300) has a computer such as a server and related peripheral devices. Figure 6 The driving sensor (24) for detecting the physical values ​​of the conveying motor (701) and the pushing motor (702) of the driving unit (13) is merely exemplified.

[0034] Each driving sensor (24) detects the physical value of the constituent elements of the driving unit (13) in analog or digital quantities all the time, periodically or when necessary, and sends the detected physical value to the physical property storage device (25), and the physical property storage device (25) stores the received physical value in a specified storage area. When detecting the physical value in the driving unit (13), each driving sensor (24) converts the analog value into a digital value, and sends the detected physical value of the digital quantity in the driving unit (13) as a numerical, scored or graded driving log to the physical property storage device (25), and the physical property storage device (25) stores the received driving log in a specified storage area. In addition, the physical property storage device (25) stores the conveying log and the storage log as a driving log together with the working time of the conveying motor (701) and the pushing motor (702) measured by the timing encoder (45). The physical values ​​detected by the drive unit (13) are digitized, scored or graded, and are divided into ratios of raw values ​​detected by the drive sensor (24), reference values ​​or a plurality of predetermined grades or levels, and stored in a physical property storage device (25).

[0035] The drive sensors (24) can be configured such that each drive sensor (24) converts the physical value of the analog quantity into a digital quantity or a digital value, and sends the detected physical value of the digital quantity in the drive unit (13) as a digitized, scored or graded drive log to the physical property storage device (25). Alternatively, the drive sensors (24) can be configured such that each drive sensor (24) directly sends the detected physical value of the analog quantity to the physical property storage device (25), and the physical property storage device (25) converts the received physical value of the analog quantity into a digital quantity, and converts the physical value of the digital quantity into a digitized, scored or graded drive log for storage.

[0036] The physical property storage device (25) stores the conveying log or the storage log as a driving log together with the working time of the conveying motor (701) and the pushing motor (702) measured by the timing encoder (45). The physical property storage device (25) stores inherent identification information such as the serial number for identifying each driving unit (13) or each paper sheet processing device (1) while storing the driving log detected by the driving sensor (24). When a request signal is received from the input device (405) of the central management device (300), after a certain period of time or automatically, the physical property storage device (25) sends the stored driving log and inherent identification information to the terminal retrieval device (401) via the connection device (25a), so that the terminal retrieval device (401) stores the driving log and inherent identification information.

[0037] The central management device (300) receives the drive log and inherent identification information sent from the connection device (25a), and converts the physical values ​​detected from the drive unit (13) into scores. The central management device (300) converts the physical values ​​of the identification conveying device (5) or the storage conveying device (6) into scores, such as the time elapsed since the last replacement date or maintenance date of the drive unit (13), the number of working times, the total number of working times, the maximum temperature during operation, the number of working stops, and the conveying accuracy (conveying deviation) of the paper sheet, and sends them to the central storage device (403) and stores them in the central storage device (403). When the total score of the physical values ​​of the identification conveying device (5) or the storage conveying device (6) falls outside a predetermined range, the characteristic comparison device (402) of the central management device (300) determines the possibility of at least one of the identification conveying device (5) and the storage conveying device (6) failing in the future, and the central management device (300) generates a warning signal or notifies the administrator of the necessity of replacing or maintaining the drive unit (13).

[0038] For example, assuming that the total physical value of a new drive unit (13) is set to 100 points, and the total physical value of the drive unit (13) detected when a fault occurs is set to 70 points, the central management device (300) notifies the manager of the necessity of replacing or maintaining the drive unit (13) when the total physical value of the drive unit (13) after use drops to 80 points. If the operator replaces the drive unit (13) in response to the notification, the actual fault of the drive unit (13) can be prevented. For example, when the maximum temperature of the operating conveying motor (701) or the pushing motor (702) exceeds 90°C or the average temperature exceeds 80°C, the total physical value of the drive unit (13) is deducted. In addition, the total physical value of the drive unit (13) is deducted according to the increase in the elapsed time, the number of operations, the total number of operations, and the number of work stops. Furthermore, when the total number of rotations of the conveying motor (701) or the pushing motor (702) exceeds 500,000 times since the paper sheet processing device (1) was shipped from the factory or the driving unit (13) was last replaced, the total physical value of the driving unit (13) is deducted.

[0039] A characteristic comparison device (402) is capable of calculating the replacement period or replacement priority of a drive unit (13) by using an algorithm for converting statistics in another method. If the central management device (300) receives the drive log and inherent identification information sent by the connection device (25a), the characteristic comparison device (402) compares the drive log received by the central management device (300) with the failure rate curve characteristic of the drive unit (13) stored in the central storage device (403). The characteristic comparison device (402) determines which current position on the failure rate curve characteristic of the drive unit (13) the degradation degree of the received drive log corresponds to, and calculates the latest replacement period or the remaining time or remaining days until the replacement period of the drive unit (13) whose wear amount (degradation degree) before the wear failure period of the total working time reaches 80% based on the corresponding position of the degradation degree on the failure rate curve characteristic, and displays the calculated latest replacement period on the display device (404).

[0040] On the other hand, if the central management device (300) receives the drive log and inherent identification information sent by the connection device (25a), the characteristic comparison device (402) substitutes the drive log indicating the current degree of degradation received by the central management device (300) into the failure rate approximation function of the drive unit (13) stored in the central storage device (403). The characteristic comparison device (402) calculates the most recent replacement period or the remaining time or remaining days until the replacement period of the drive unit (13) whose wear amount (degree of degradation) before the wear failure period of the total working time reaches 80% based on the corresponding position of the degree of degradation on the failure rate approximation function, and displays the calculated most recent replacement period on the display device (404).

[0041] The amount of change in the physical value from the drive sensor (24) indicates the time-dependent change, i.e., the degree of degradation, of the drive unit (13) displayed on the horizontal axis of the failure rate curve characteristic. The physical property storage device (25) has a built-in oscillator or oscillation circuit that generates a time (clock) signal, and has the function of calculating the duration, speed, and acceleration of the physical value from the drive sensor (24) based on the time signal generated by the oscillation circuit. The inherent identification information for identifying the drive unit (13) or the paper processing device (1) installed with the physical property storage device (25) and the past maintenance and inspection history of the drive unit (13) being repaired or inspected are also stored in the physical property storage device (25).

[0042] Unlike the structure of Patent Document 1, the identification and transporting device (5) according to the embodiment of the present invention has Figure 6 The driving sensor (24) shown has the following functions: counting each working time of the conveying motor (701) and sending the counted time signal to the conveying counter (241) of the physical property storage device (25); counting the current value and the number of overcurrents flowing through the conveying motor (701) each time the conveying motor (701) works, and sending the counted high current value, high current time and high current number of signals to the overcurrent detection resistor or conveying ammeter (242) of the physical property storage device (25); and measuring the ambient temperature of the conveying motor (701) and its high temperature duration each time the conveying motor (701) works, and sending the counted digital signals of the ambient temperature, high temperature duration and high temperature number of signals to the conveying temperature sensor (243) of the physical property storage device (25).

[0043] The drive sensor (24) further comprises: a conveying timer (244) for counting the total working time and the number of working times required for the conveying motor (701) to work each time the conveying motor (701) works, and sending the digital signals obtained by counting as a drive log to a physical property storage device (25); a conveying acceleration sensor (245) such as a crystal acceleration sensor for counting the low acceleration and the number of low acceleration times of the conveying motor (701) each time the conveying motor (701) works, and sending the digital signals obtained by counting as a drive log to a physical property storage device (25); and a conveying speed sensor (246) for counting the rotation speed of the conveying motor (701) each time the conveying motor (701) works, and sending the speed digital signal obtained by counting as a drive log to a physical property storage device (25).

[0044] Similar to the conveying motor (701), a Figure 6The driving sensor (24) comprises: each time the pushing motor (702) works, the working time of the pushing motor (702) is counted, and the digital time signal obtained by counting is sent as a driving log to the storage counter (251) of the physical property storage device (25); each time the pushing motor (702) works, the current value and the number of overcurrents flowing through the pushing motor (702) are counted, and the digital signals of the high current value, the high current time and the number of high currents obtained by counting are sent as a driving log to the overcurrent detection resistor and the storage ammeter (252) of the physical property storage device (25); each time the pushing motor (702) works, the ambient temperature and the high temperature duration of the pushing motor (702) are measured, and the digital signals of the ambient temperature, the high temperature duration and the number of high temperature obtained by counting are sent as a driving log to the storage temperature sensor (253) of the physical property storage device (25).

[0045] In addition, the drive sensor (24) has: each time the push motor (702) works, the total working time and the number of times required for the push motor (702) to work are counted, and each digital signal obtained by counting is sent as a drive log to a storage timer (254) of the physical property storage device (25); each time the push motor (702) works, the low acceleration of the motor and the number of times, and each digital signal obtained by counting is sent as a drive log to a storage acceleration sensor (255) such as a crystal acceleration sensor of the physical property storage device (25); and each time the push motor (702) works, the rotation speed of the push motor (702) is counted, and the digital speed signal obtained by counting is sent as a drive log to a storage speed sensor (256) of the physical property storage device (25).

[0046] For example, a known temperature measuring device that displays a resistance change or a current value change caused by a temperature change of each motor winding of the conveying motor (701) and the pushing motor (702) in a digital signal can be used for the conveying and storage temperature sensors (243, 253). In short, the workload time of the conveying motor (701) and the pushing motor (702) is measured by counting the clock (elapsed time) signal of the time by the timing encoder (45). The physical property storage device (25) stores the drive log from the drive sensor (24) together with the workload time of the drive unit (13) measured by the timing encoder (45).

[0047] Therefore, the transport and storage temperature sensors (243, 253) detect the temperatures of the transport motor (701) and the push motor (702) whenever the transport device (5) and the push device (7) are identified to be working, and generate a transport detection signal obtained by converting the detected temperature into a digital signal, which is sent and stored in the physical property storage device (25). The temperature value converted into a digital signal is displayed as a numerical, scored or graded drive log and stored in the physical property storage device (25). The transport and storage speed sensors (246, 256) detect the rotation speeds of the transport motor (701) and the push motor (702) whenever the transport device (5) and the push device (7) are identified to be working, and generate a speed detection signal obtained by converting the detected rotation speed into a digital signal, which is sent and stored in the physical property storage device (25). The speed detection signal converted into a digital signal is displayed as a numerical, scored or graded drive log and stored in the physical property storage device (25). It should be noted that the amount of decrease in the physical value from the conveying and storage speed sensors (246, 256), that is, the speed detection signal converted into a digital signal, represents the degree of deterioration of the drive unit (13).

[0048] The main cause of failure of the drive unit (13) can be considered to be the following time-dependent change, i.e., degradation, of the operating parts constituting the conveying motor (701) or the pushing motor (702) and the power transmission device (8). Therefore, the following will study the pre-failure replacement method of the drive unit (13) according to each degradation cause.

[0049] 1. Wear and tear during the total working time,

[0050] 2. Fatigue failure caused by repeated work accumulation,

[0051] 3. Overcurrent damage caused by repeated overloads,

[0052] 4. Thermal damage in high temperature environment,

[0053] 5. Abnormal movement speed reduction,

[0054] 6. Abnormal movement acceleration is reduced,

[0055] 7. Seizure of mechanical sliding parts (cogging effect)

[0056] wear and tear

[0057] Wear failure of the sliding part of the conveying motor (701) or the pushing motor (702) occurs due to the wear caused by the passage of the total working time of each conveying and pushing motor (701, 702). Until the wear failure occurs, the wear amount of each conveying and pushing motor (701, 702) can be considered to be proportional to the total working time of each conveying and pushing motor (701, 702). Therefore, the working time of each conveying motor (701) and the pushing motor (702) is counted by the conveying and storage counter (241, 251), and the time signal obtained by the count is sent to the physical property storage device (25). The physical property storage device (25) calculates and stores the total working time of each conveying and pushing motor (701, 702).

[0058] Figure 7 A bathtub (bathtub type) curve characteristic or failure rate curve characteristic is shown, with the vertical axis representing the failure rate of the drive unit (13) and the horizontal axis representing the total working time or total number of working times of the machine. The failure rate curve characteristic shown in the figure is composed of three periods in time series: an initial failure period, an occasional failure period, and a wear failure period. In this specification, the initial failure period for ensuring the quality of the drive unit (13) and the stable occasional failure period for expecting stable continuous operation are not considered, but the focus is on the failure rate rising point (T) in the second half of the occasional failure period when the failure rate increases sharply toward the wear failure period.

[0059] For example, if the failure rate rise point (T) corresponding to 500 hours is reached at 90% of the total operating time of the conveying motor (701) or the pushing motor (702) having a sliding portion, and it is judged from the experimental value or maintenance activity that the accidental failure period has entered the wear failure period, then when the wear amount (deterioration degree) before the wear failure period of the total operating time of each conveying and pushing motor (701, 702) reaches 80% of 400 hours, a warning signal can be generated from the physical property storage device (25) to inform the manager of the replacement of the drive unit (13). In short, based on the failure rate rise point (T) represented by the failure rate curve characteristic or the failure rate approximate function, the period of 70% to 90% before it is set as the replacement period of the drive unit (13), and when the replacement period of the drive unit (13) is reached, an audible alarm or a visual alarm can be generated from the warning device connected to the physical property storage device (25) as a warning signal from the physical property storage device (25). Assuming that components of the paper sheet identification device (1) other than the drive unit (13) do not suffer from wear, fatigue, or thermal damage and that failures rarely occur, the failure rate curve characteristic of the paper sheet identification device (1) returns to the original point after the drive unit (13) is replaced.

[0060] Fatigue accumulation

[0061] Even under low load conditions, the conveying motor (701) or the pushing motor (702) accumulates fatigue due to the reduction in the allowable stress of the material caused by repeated operation, and fatigue failure may occur. Fatigue failure of each conveying and pushing motor (701, 702) occurs according to the accumulated number of operations, and Figure 7 The failure rate curve characteristics shown are similar. Until fatigue failure occurs, the fatigue accumulation of each conveying and pushing motor (701, 702) can be considered to be proportional to the cumulative repeated operation times of each conveying and pushing motor (701, 702). Therefore, the operation times of each conveying motor (701) and pushing motor (702) are counted by conveying and storage counters (241, 251) or other counters, and the counted operation times signal is sent to the physical property storage device (25). The physical property storage device (25) calculates and stores the cumulative operation times of each conveying and pushing motor (701, 702). Based on experience, it is assumed that fatigue damage occurs when the cumulative number of operations of each conveying and pushing motor (701, 702) reaches, for example, 500,000 times. When the cumulative number of operations of each conveying and pushing motor (701, 702) reaches 400,000 times at which the wear amount reaches 80%, a warning signal can be generated from the physical property storage device (25) to urge the administrator to replace the drive unit (13).

[0062] Overcurrent damage

[0063] Due to some reasons, the components are deformed and the smooth operation of the driving unit (13) is hindered. Compared with the deformation of the components, a larger load is generated during operation, and sometimes an overcurrent flows through the conveying motor (701) or the pushing motor (702). If the overcurrent flows frequently, the electronic components in the conveying motor (701) or the pushing motor (702) are thermally damaged or broken down due to overheating caused by the overcurrent or discharge of the breakdown current, and the conveying motor (701) or the pushing motor (702) sometimes fails. Therefore, the overcurrent detection resistor and the conveying and storage ammeter (242, 252) for counting the high current value, high current time and high current number of times are used to detect and count the current value, high current duration and overcurrent load number of the overcurrent flowing through the conveying motor (701) or the pushing motor (702), and the signals of the high current value, high current duration and high current number obtained by detection and counting are sent to the physical property storage device (25). The physical property storage device (25) calculates and stores the high current value, high current time, and high current frequency of the conveying motor (701) or the pushing motor (702). When the current value flowing through the conveying motor (701) or the pushing motor (702) is, for example, 10 amperes or more, the power-on time exceeds 3 seconds, and the power-on frequency exceeds 5 times, it is determined that the component may be thermally damaged or broken down due to the high current. At this time, a warning signal can be generated from the physical property storage device (25) to prompt the administrator to replace the drive unit (13).

[0064] Thermal damage in high temperature environments

[0065] When a resin-sealed electronic component installed on a conveying motor (701) or a pushing motor (702) is exposed to a high temperature of 120°C or more, a semiconductor chip built into the electronic component may be thermally damaged or broken down, and the expected function may not be achieved. Therefore, by setting a conveying and storage temperature sensor (243, 253) for measuring the ambient temperature and high temperature duration of the conveying motor (701) or the pushing motor (702), the ambient temperature, high temperature duration, and high temperature frequency are counted each time the conveying and pushing motor (701, 702) is working, and the signals of the counted ambient temperature, high temperature duration, and high temperature frequency are sent to a physical property storage device (25). The physical property storage device (25) calculates and stores the counted ambient temperature, high temperature duration, and high temperature frequency. For example, when the high temperature of 120°C or more is more than 30 seconds and exceeds 3 times, it is judged that the electronic component may be thermally damaged or broken down due to the high temperature environment, and a warning signal can be generated from the physical property storage device (25) to urge the manager to replace the drive unit (13).

[0066] Reduced movement speed

[0067] Due to specific reasons or complex degradation, the operating speed of the drive unit (13) may sometimes decrease. For example, if an adhesive material attached to a sheet of paper transported along the identification conveying path (10) adheres to a part of the identification conveying device (5) or the storage conveying device (6) or foreign matter is mixed in, the operating performance of the drive unit (13) is greatly reduced. Therefore, by counting the total working time and the number of times required for the operation of the conveying motor (701) or the pushing motor (702), the low working speed of the motor (701, 702) and the number of times are counted, and the signals obtained by the count are sent to the physical property storage device (25). The physical property storage device (25) calculates and stores the low working speed and the number of times of the low working speed of the conveying and pushing motor (701, 702) obtained by the count. When the specified number of low working speeds is counted, a warning signal is generated from the physical property storage device (25) to prompt the administrator to replace the drive unit (13).

[0068] For example, when a user of a paper sheet processing device (1) spills a viscous liquid such as a beverage onto an inlet (14) of an identification conveying path (10), the viscous liquid adheres to the identification conveying device (5), the storage conveying device (6), the push device (7) or the power transmission device (8), and the conveying speed of the conveying and pushing motors (701, 702) is delayed or changed. The central management device (300) always monitors the conveying speed change of the conveying and pushing motors (701, 702), and when the conveying and pushing motors (701, 702) do not operate at a predetermined speed, it is determined that the viscous liquid adheres to the identification conveying device (5), and a warning signal is generated or a manager is notified to replace the drive unit (13). In addition, when foreign matter such as dust or sand intrudes into the identification conveying path (10) from the inlet (14) of the identification conveying path (10), the conveying speed of the conveying and pushing motors (701, 702) is changed due to the adhesion or accumulation of the foreign matter on the power transmission device (8). A plurality of conveying sensors (241-246) are used to quantify conveying delays caused by foreign matter, monitor increases in conveying loads, and generate warning signals or notify managers to replace drive units (13).

[0069] Reduced movement acceleration

[0070] Sometimes, due to deformation of components or other reasons, the acceleration of the drive unit (13) is reduced, and the rotational force required for conveying or storing paper sheets is reduced. Therefore, the low acceleration and the number of times of the conveying and pushing motors (701, 702) are counted by conveying and storing acceleration sensors (245, 255) such as crystal acceleration sensors, and each signal obtained by the count is sent to a physical property storage device (25). The physical property storage device (25) calculates and stores the counted low acceleration and the number of times of the motor. When the low operating speed is counted for a specified number of times, a warning signal can be generated from the physical property storage device (25) to prompt the administrator of the necessity of replacing the drive unit (13).

[0071] The transport and storage acceleration sensors (245, 255) detect the accelerations of the transport motor (701) and the push motor (702), and generate acceleration detection signals obtained by converting the detected accelerations into digital signals whenever the transport device (5) and the push device (7) are working, and the acceleration detection signals are sent out as a drive log and stored in the physical property storage device (25). The acceleration signals converted into digital signals are displayed as a numerical, scored or graded drive log and stored in the physical property storage device (25). The physical value from the transport and storage acceleration sensors (245, 255), that is, the decrease in the speed detection signals converted into digital signals, indicates the degree of degradation of the drive unit (13).

[0072] Cogging of the drive unit

[0073] If a jam (tooth groove effect) occurs in a part of the degraded identification conveying device (5), the conveying speed of the paper sheet will deviate (uneven), the optical image of the paper sheet will be missing, deformed, shortened, stretched or slipped, and the photoelectric identification sensor (11) cannot obtain appropriate image information of the paper sheet, and the judgment device (12) may sometimes be unable to correctly judge the authenticity of the paper sheet based on the optical image of the paper sheet. For example, if the judgment device (12) cannot correctly read the identification mark such as the barcode printed on the paper sheet, the judgment device (12) generates an error signal, causing the drive unit (13) to reverse and forward, and then judge the authenticity of the paper sheet again. The physical property storage device (25) stores the number of times the judgment device (12) judges the authenticity of the paper sheet as a drive log.

[0074] Idle rotation and slippage of the drive unit

[0075] The characteristic comparison device (402) compares the length information of the paper sheet sent from the physical property storage device (25) to the terminal retrieval device (401) with the regular length stored in the central storage device (403). If the image length signal read by the identification sensor (11) deviates from the specified range, the characteristic comparison device (402) determines that idling (slipping) has occurred during the belt drive of the drive unit (13). The physical property storage device (25) counts the number of idling occurrences during the belt drive, and reads the number of idling occurrences during the belt drive from the physical property storage device (25) in the terminal retrieval device (401) through the input device (405), the terminal retrieval device (401) and the connecting device (25a). If the number of idling occurrences exceeds a certain number stored in the central storage device (403), the characteristic comparison device (402) determines that the identification conveying device (5) is faulty. For example, by storing a storage log from a storage ammeter (252), a storage acceleration sensor (255), or a storage speed sensor (256) indicating the operating delay time or operating current level of a storage conveying device (6) in a physical property storage device (25), it is possible to notify an administrator to replace the drive unit (13) before the storage chamber (79) of the storage device (3) is filled with paper sheets.

[0076] For example, the accumulated pulse width of the drive signal to the storage conveying device (6) or the pushing device (62) may be measured, and when a certain accumulated pulse width is detected, it is detected that the storage chamber (79) is full of paper sheets. It is also possible to store the inherent identification information of the paper sheet processing device (1) or the drive unit (13) having a storage chamber (79) that is frequently full of paper sheets in the physical property storage device (25), and replace the storage device (3) that is detected to be deteriorated.

[0077] As described above, due to various factors such as the increase in the total working time or the cumulative number of repeated working times of the drive unit (13) including the conveying motor (701), the pushing motor (702) and the power transmission device (8), changes in ambient temperature, abnormal rotation output, increase in wear, reduced function or strength due to repeated actions, increased fatigue due to repeated low loads, and idling (slipping) during belt driving, the quality, performance and function of each component of the drive unit (13) are bound to decrease, and deteriorate in stages or gradually.

[0078] However, if the mechanical structure and electrical structure of the drive unit (13) and their functions are specifically determined, the failure rate curve characteristics of the drive unit (13) related to wear, fatigue, overcurrent damage, thermal damage, reduced motion speed and reduced motion acceleration as the cause of the failure can be measured, imagined, or displayed by a failure rate approximation function, and the failure rate curve characteristic data or the failure rate approximation function are stored in the central storage device (403). The obtained failure rate curve characteristics or failure rate approximation function are sometimes also composed of a bathtub curve or other different failure rate characteristic curves, quadratic curves or straight lines. The working experience values ​​of the drive unit (13): total working time, total working times, ambient temperature, high temperature duration, high temperature times, low working speed, low working speed times, low acceleration, low acceleration times and the inherent identification information of the drive unit (13), i.e., the game console (200), are stored in the physical property storage device (25). The working experience value of the drive unit (13) can be read from the physical property storage device (25) in the terminal search device (401) through the input device (405), the terminal search device (401) and the connection device (25a).

[0079] If degradation data such as the current total working time and total working times are retrieved from the physical property storage device (25) through the input device (405), the terminal retrieval device (401) and the connection device (25a), and the degradation data is input (plotted) or substituted into the failure rate curve data or the failure rate approximate function stored in the central storage device (403), the degradation state of the drive unit (13) on the failure rate curve characteristics or the failure rate approximate function can be clearly identified, and the failure rate rising point (T) on the failure rate curve characteristics or the failure rate approximate function and the appropriate replacement position of the drive unit (13) can be identified before failure.

[0080] A drive unit (13) is built into an installation room (21) of an identification device (2) installed in each paper processing device (1) of a plurality of gaming machines (200) installed in a gaming hall or a club. A physical property storage device (25) of each drive unit (13) is connected to a terminal search device (401) of a central management device (300) via a connection device (25a). A search command signal can be input to the terminal search device (401) from an input device (405) such as a keyboard or an image input device connected to the terminal search device (401) of the central management device (300), and information in the physical property storage device (25) of the drive unit (13) storing a drive log of physical values ​​and inherent identification information can be retrieved via the terminal search device (401) and the connection device (25a), and necessary information can be retrieved.

[0081] like Figure 1 to Figure 3As shown, the paper sheet processing device (1) comprises: an installation chamber (21) formed in a housing (20) of an identification device (2) and configured with a drive unit (13); and a pair of pivot support parts (161) formed on the inner wall of the installation chamber (21). Figure 2 The drive unit (13) shown is as follows Figure 5 The identification device (2) is detachably mounted in the installation chamber (21) of the identification device (2). That is, the hinge tube (160) of the frame (13b) of the drive unit (13) can be detachably and rotatably mounted on the pivot support portion (161) of the housing (20) of the identification device (2), so that the frame (13b) rotates around the pivot support portion of the identification device (2), thereby accommodating the drive unit (13) in the installation chamber (21) of the identification device (2).

[0082] It is also possible to prevent the drive unit (13) from being removed from the paper processing device (1) during the power supply from the power source linked to the opening and closing of the bottom cover (13a) of the drive unit (13). After the power supply to the paper processing device (1) is temporarily stopped by opening and closing the bottom cover (13a) of the drive unit (13), when it is restarted, the terminal search device (401) detects the connection between the paper processing device (1) or the drive unit (13) and the connection device (25a) within a short time.

[0083] like Figure 5 As shown, if a terminal retrieval device (401) is connected to a connection device (25a) provided on a physical property storage device (25) of a drive unit (13) in an installation room (21) that accommodates an identification device (2), the terminal retrieval device (401) can access, retrieve and retrieve a drive log or warning signal stored in the physical property storage device (25) in accordance with a command signal given to the terminal retrieval device (401) from an input device (405) outside the paper sheet processing device (1), and display the drive log or warning signal on a display device (404) or generate an alarm.

[0084] The central management device (300) comprises: a central storage device (403) for storing the failure rate curve characteristics or failure rate approximation function of the drive unit (13); and a characteristic comparison device (402) connected to the central storage device (403) and the terminal search device (401). The characteristic comparison device (402) is capable of comparing the physical value of the drive unit (13) received by the terminal search device (401) with the failure rate curve characteristics of the drive unit (13) stored in the central storage device (403) or substituting the physical value of the drive unit (13) into the failure rate approximation function, calculating the most recent replacement period of the drive unit (13), and outputting and displaying it on a display device (404).

[0085] The current degree of degradation is determined based on the accumulated working physical values ​​of the drive unit (13) read out by the terminal retrieval device (401). By comparing the failure rate curve characteristics stored in the central storage device (403) with the accumulated working physical values ​​or substituting the accumulated working physical values ​​of the drive unit (13) into the failure rate approximation function, the failure rate rising point (T) of the failure rate curve characteristics and the period when the degree of degradation reaches 80% before the wear failure period can be predicted.

[0086] The identification sensor (11) of the identification device (2) reads the image information of the paper sheet of the banknote or coupon inserted into the paper sheet processing device (1), and the determination device (12) determines the authenticity of the paper sheet. The determination device (12) is also connected to the physical property storage device (25). A coupon of a specified size is inserted into the identification device (2), and the image length signal read by the identification sensor (11) is sent from the determination device (12) to the physical property storage device (25). The regular size information of the banknote or coupon is also stored in the central storage device (403). For the size and style of the coupon issued in the club facility and collected in a short time, the regular size and style can be maintained with less deterioration such as wrinkles, and a good reference value for measuring the conveying accuracy of the drive unit (13) is provided to the determination device (12) and the physical property storage device (25).

[0087] Compared with the paper money in normal circulation, the restricted coupons with limited usage period and usage area are less degraded, and the optical reading size of the identification sensor (11) does not change. Therefore, if the driving unit (13) has a conveying abnormality, the paper page image information that deviates from the specified range is sent from the identification sensor (11) to the judgment device (12) and the physical property storage device (25). If the paper page image information outside the specified range is generated, the judgment device (12) causes the identification conveying device (5) to reverse and rotate forward and perform paper page identification again. The physical property storage device (25) counts the number of re-identifications. If it exceeds a certain number of re-identifications such as 5 times, it is determined that the conveying function of the identification conveying device (5) has degraded, and a warning signal is generated.

[0088] In addition, if the identification sensor (11) detects a banknote longer than a specified length, it can be determined that the identification conveying device (5) or the storage conveying device (6) is worn, idle or slipped, and the administrator is notified. For example, if the rubber roller of the identification conveying device (5) or the storage conveying device (6) is worn, the number of rotations of the rubber roller increases, and the banknote is detected as longer than the average length. If the rubber roller of the identification conveying device (5) or the storage conveying device (6) idles or slips, it is detected as a banknote with a large variation in average length. The identification sensor (11) of the identification device (2) can also read the barcode of the coupon, confirm the length, angle or encoder pulse interval of the coupon, and thus determine the degree of deterioration of the drive unit (13).

[0089] The central management device (300) can also automatically notify the manager of the deterioration of the drive unit (13) and the need for replacement, for example, determine the repair location, and prompt the manager of the repair method based on the past maintenance and inspection history. The central management device (300) can also determine the warranty period based on the S / N (signal to noise) ratio data, display the replacement history, prompt the motor replacement based on the number of motor operations, determine the degradation based on the values ​​of the conveying motor (701) and the pushing motor (702), determine the wear of the gears, determine the progress of the degradation based on the average external temperature, and confirm the content and number of error codes returned. The central management device (300) can register the content and countermeasures of the error or replace the parts, determine the tendency of the repair, and complete the maintenance as soon as possible.

[0090] When manufacturing the paper sheet processing device of the present invention, one or more drive sensors (24) for detecting physical values ​​in the drive unit (13) and a physical property storage device (25) for storing the physical values ​​detected by the drive sensor (24) are provided in the drive unit (13). Then, the drive unit (13) having the drive sensor (24) and the physical property storage device (25) is detachably installed in an installation chamber (21) of an identification device (2) for identifying the authenticity of paper sheets, thereby forming an identification conveying path (10) for conveying paper sheets in the drive identification device (2) along the drive unit (13).

[0091] Therefore, the method for displaying the degree of degradation of a paper sheet processing device of the present invention includes: a process of setting one or more drive sensors (24) for detecting physical values ​​in the drive unit (13) and a physical property storage device (25) for storing the physical values ​​detected by the drive sensor (24) in the drive unit (13); a process of detachably installing the drive unit (13) having the drive sensor (24) and the physical property storage device (25) in an identification device (2) for identifying the authenticity of paper sheets; a process of conveying a plurality of paper sheets along an identification conveying path (10) formed in the drive identification device (2) by the drive unit (13); a process of retrieving the physical values ​​stored in the physical property storage device (25) by a terminal retrieval device (401) and taking out the physical values; and a process of displaying the taken out physical values ​​on a display device (404).

[0092] The method for displaying the degree of degradation of a paper sheet processing device of the present invention may also include: a process of inputting a physical value retrieved by a terminal retrieval device (401) into a characteristic comparison device (402); a process of comparing a failure rate curve characteristic of a drive unit (13) stored in a central storage device (403) with a physical value received by a characteristic comparison device (402) or substituting the physical value received by the characteristic comparison device (402) into a failure rate approximation function of the drive unit (13) stored in a central storage device (403); and a process of calculating a most recent replacement period based on the physical value of the drive unit (13) through the characteristic comparison device (402) and displaying the most recent replacement period on a display device (404).

[0093] In an embodiment of the present invention, a method for detecting wear caused by the total working time of the drive unit (13), fatigue accumulation caused by the cumulative number of repeated working times, overcurrent damage caused by repeated overloads, thermal damage in a high temperature environment, abnormal reduction in movement speed, abnormal reduction in movement acceleration, and faults caused by sticking (cogging effect), idling and sliding is described. However, other mechanical or electrical faults, problems or malfunctions of the drive unit (13) can be detected by the drive sensor (24) and stored in the physical property storage device (25). When the fault time or the number of faults exceeds a certain level, a warning signal is generated from the physical property storage device (25) to remind the replacement of the drive unit (13).

[0094] The embodiments of the present invention can be modified. For example, when the rate of change of the motor control value of the identification conveyor (5) or the storage conveyor (6) exceeds 10%, it can be judged that the gear, belt or roller is dirty or worn, and the manager is notified. In addition, the average speed when the motor is driven at a certain torque can be measured by an encoder to quantify the conveying load of the identification conveyor (5) or the storage conveyor (6). As another method, the time until the target speed of the motor is reached can be measured to quantify the conveying load of the identification conveyor (5) or the storage conveyor (6). In addition, the customer code and the date of shipment can be written and stored in the physical property storage device (25) of the drive unit (13) before the paper sheet processing device (1) is shipped. The warranty period of the paper sheet processing device (1) or the drive unit (13) can be determined, and the resale of second-hand goods of the above-mentioned equipment can be suppressed.

[0095] Although not shown in the figure, the central management device (300) can also notify the mobile terminal of the manager of the facility where the paper sheet processing device (1) or the paper sheet processing device (1) is installed of the physical value of the drive unit (13) or the replacement of the drive unit (13). The manager of the paper sheet processing device (1) can show the physical value of the drive unit (13) to the manager of the facility to prove that the quality of the paper sheet processing device (1) is maintained. In addition, since the physical property storage device (25) stores the inherent identification information of the drive unit (13) or the paper sheet processing device (1), when the physical value of the drive unit (13) stored in the physical property storage device (25) is an abnormal value, the manager can investigate the actual use environment of the drive unit (13) or the paper sheet processing device (1).
