Description

[Technical field]

[0001] An embodiment of the present invention relates to a conveying device and an automatic ticket gate device. [Background technology]

[0002] The automatic ticket gate device is equipped with a conveying device that has a pair of rollers and a pressing mechanism that presses one of the pair of rollers against the other roller, and conveys ticket media such as magnetic tickets. When multiple ticket media are inserted into the insertion slot at the same time, the separating device as a conveying device separates them one by one with the pair of rollers. The pair of rollers face each other with a gap between them, and by adjusting the gap to a size that allows only one ticket medium to pass through, the multiple ticket media can be separated one by one.

[0003] The gap is adjusted to a desired size by separating one roller from the other roller, taking into account the displacement of the one roller due to the pressing, based on the position of the one roller when pressed against the other roller. If the pair of rollers wear unevenly and the amount of wear is greater than a predetermined value, the gap between the pair of rollers cannot be completely eliminated when one roller is pressed against the other roller, and a gap may remain in the area where the amount of wear is large. Therefore, even if the other roller is separated taking into account the amount of displacement, the size of the gap between the pair of rollers will be larger than the desired size. If the size of the gap cannot be adjusted to an appropriate range, separation failure may occur. [Prior art documents] [Patent documents]

[0009] Hereinafter, the embodiment of the present invention will be described with reference to the drawings. Note that the disclosure is merely an example, and any suitable modification that a person skilled in the art can easily conceive of while maintaining the gist of the invention is naturally included in the scope of the present invention. In addition, in order to make the drawings and explanation clearer, the width, thickness, shape, etc. of each part may be shown in a schematic manner compared to the actual embodiment, but this is merely an example and does not limit the interpretation of the present invention. In this specification and each figure, elements similar to those described above with respect to the previous figures may be given the same reference numerals, and detailed explanations may be omitted as appropriate. Hereinafter, an automatic ticket gate device according to an embodiment will be described in detail with reference to the drawings. Also, a separation device will be described as an example of a conveying device according to an embodiment.

[0010] FIG. 1 is a cross-sectional view showing an automatic ticket gate device 10 according to an embodiment. As shown in Fig. 1, the automatic ticket gate device 10 includes an insertion slot EN, a separation device 20, an alignment device 100, a magnetic processing device 110, a punching and printing device 120, a discharge and ticket collecting device 130, and a discharge slot EX. The separation device 20, the alignment device 100, the magnetic processing device 110, the punching and printing device 120, and the discharge and ticket collecting device 130 each have a transport mechanism that transports the ticket medium P inserted from the insertion slot EN along a transport path. The ticket medium P is, for example, a magnetic ticket.

[0011] The insertion slot EN has dimensions (length, width, height) that allow multiple magnetic tickets, for example, four magnetic tickets, to be inserted in a stacked state. When a plurality of ticket media P are inserted simultaneously (stacking) into the insertion slot EN, the separating device 20 separates the ticket media P one by one and conveys them to the aligning device 100 one by one. The alignment device 100 aligns the conveying direction and position of the ticket medium P conveyed from the separation device 20 , and conveys the ticket medium P to the magnetic processing device 110 . The magnetic processing device 110 performs magnetic processing on the ticket medium P transported from the alignment device 100. For example, when using the automated ticket gate device 10 to enter a station, the magnetic processing may include recording information such as the entrance station and the entrance time on the ticket medium P. The magnetic processing device 110 transports the magnetically processed ticket medium P to the punching and printing device 120.

[0012] The punching and printing device 120 punches holes in the ticket medium P transported from the magnetic processing device 110 to indicate that the ticket has passed through the automated ticket gate device 10, and prints necessary information on the ticket medium P. The punching and printing device 120 transports the punched and printed ticket medium P to the ticket dispensing and collecting device 130. The ticket discharging / collecting device 130 discharges from the discharge port EX the ticket medium P transported from the punching / printing device 120. At this time, if multiple ticket media P, for example two sheets, are inserted into the insertion port EN at the same time, separated by the separating device 20, and transported sequentially to the alignment device 100, the magnetic processing device 110, and the punching / printing device 120, the two ticket media P are collected by the ticket discharging / collecting device 130 and are discharged from the discharge port EX at the same time.

[0013] The configuration of the separation device 20 will be described with reference to FIGS. Fig. 2 is a side view showing the separation device 20 of the automatic ticket gate device 10 according to the embodiment. Fig. 3 is a perspective view showing a part of the separation device 20 shown in Fig. 2. Fig. 4 is a side view seen from the arrow A in Fig. 2. Note that the frame Fr is omitted in Figs. 2 and 3. First, the first direction X, the second direction Y, and the third direction Z shown in Figures 2 to 4 will be defined. The first direction X corresponds to the length direction of the certificate medium P. The second direction Y corresponds to the thickness direction of the certificate medium P. The third direction Z corresponds to the width direction of the certificate medium P. As shown in Figures 2 to 4, the separation device 20 includes a conveying mechanism 22, a thickness detection unit 24, a feed roller 26, a separation roller 28, a displacement detection unit 30, a pickup roller 32, a support mechanism 34, and a frame Fr.

[0014] First, the basic configuration of the transport mechanism 22 will be described. The transport mechanism 22 has a transport path 36 along which the ticket medium P is transported, a first motor 38, and a second motor 40. Furthermore, the transport mechanism 22 has various motors for driving the transport path 36 in addition to the first motor 38 and the second motor 40. The transport path 36 is defined by various rollers, belts, etc. shown in FIG. The conveying path 36 is between the conveying belt B1 and the conveying roller Ra1, between the conveying belt B1 and the thickness detection unit 24, between the conveying belt B1 and the conveying belt B2, between the conveying belt B1 and the separation roller 28, and between the pickup roller 32 and the rotating body 42. In one example, the conveying path 36 extends in the first direction X. The ticket medium P inserted through the insertion slot EN is transported along the transport path 36.

[0015] The conveyor belt B1 is an endless belt. On the inside of the conveyor belt B1, conveyor rollers Ra2, Ra3, Ra4, driven rollers Rb1, Rb2, and a feed roller 26 (more specifically, conveyor roller Ra5) are located. The conveyor belt B1 is wound around the conveyor roller Ra5 and the driven rollers Rb1, Rb2. The conveyor belt B1 rotates in synchronization with the conveyor roller Ra5 and the driven rollers Rb1, Rb2. The conveyor belt B1 is urged from the outside by the driven roller Rb3.

[0016] The conveyor belt B2 is located above the conveyor belt B1. The conveyor belt B2 is an endless belt that is shorter than the conveyor belt B1. The drive roller Rc1, conveyor rollers Ra6 and Ra7, and driven roller Rb4 are located inside the conveyor belt B2. The conveyor belt B2 is wound around the drive roller Rc1 and driven roller Rb4. The conveyor belt B2 rotates in synchronization with the drive roller Rc1 and driven roller Rb4. The conveying roller Ra6 faces the conveying roller Ra3 in the second direction Y. The conveying roller Ra7 faces the conveying roller Ra4 in the second direction Y.

[0017] Next, each device included in the separator 20 will be described. The thickness detection unit 24 detects the thickness and number of the ticket media P inserted through the insertion slot EN. The thickness detection unit 24 has a contact 25 at one end in the second direction Y. The contact 25 is biased downward. The thickness detection unit 24 is a contact-type sensor that detects the thickness and number of the ticket media P based on the amount of displacement (amount of movement) of the contact 25. Note that the thickness detection unit 24 is not limited to being a contact-type sensor and may be, for example, a non-contact sensor that utilizes light reflection.

[0018] The feed roller 26 has a first roller R1, a first rotating shaft 44, and two conveying rollers Ra5. The first roller R1 is located between the two conveying rollers Ra5 in the third direction Z. The first roller R1 and the conveying roller Ra5 are fixed to the first rotating shaft 44 and can rotate around the first rotating shaft 44. The first rotating shaft 44 is connected to a first motor 38. The feed roller 26 is driven by the first motor 38. The first roller R1 is made of rubber. As described above, since the conveyor belt B1 is wound around the conveyor roller Ra5, the conveyor belt B1 can be moved by driving the feed roller 26. In one example, the ticket medium P is conveyed in the first direction X by rotating the feed roller 26 counterclockwise.

[0019] The separation roller 28 is located downstream of the thickness detection unit 24, and has a second roller R2 and a second rotation shaft 46. The separation roller 28 faces the feed roller 26 with a gap G1 in the second direction Y. More specifically, the second roller R2 faces the first roller R1 with a gap G1 in between. The size of the gap G1 is preset according to the thickness of the ticket medium P to be processed by the automated ticket gate device 10. Specifically, it is a value slightly larger than the thickness of the ticket medium P. For example, if the thickness of the ticket medium P is 0.2 mm, the size of the gap G1 is set to 0.25 to 0.3 mm. The second roller R2 is made of rubber.

[0020] The second roller R2 can rotate around a second rotating shaft 46. The second rotating shaft 46 is connected to a second motor 40. The separation roller 28 is driven by the second motor 40. The separation roller 28 performs a separation operation when multiple sheets of ticket media P are stacked and inserted into the insertion slot EN. The separation operation refers to rotating the separation roller 28 in a direction that does not feed the ticket media P in the conveying direction when the value detected by the thickness detection unit 24 is equal to or greater than a predetermined size. In one example, the separation device 20 separates multiple sheets of ticket media P by rotating the separation roller 28 counterclockwise.

[0021] The displacement detection unit 30 is provided so as to be able to detect the amount of displacement (amount of movement) of the separation roller 28 in the second direction Y. The displacement detection unit 30 has a contact 31 at one end in the second direction Y. The contact 31 is biased downward. The displacement detection unit 30 is a contact-type sensor that detects the amount of displacement of the separation roller 28 (second roller R2) based on the amount of displacement of the contact 31. Note that the displacement detection unit 30 is not limited to being a contact-type sensor, and may be, for example, a non-contact type sensor that utilizes light reflection.

[0022] The pickup roller 32 is located downstream of the feed roller 26 and the separation roller 28. The pickup roller 32 is pressed against a rotating body 42. The rotating body 42 is, for example, a bearing. The pickup roller 32 receives the certificate medium P sent out from the feed roller 26 and the separation roller 28, and transports the certificate medium P to the alignment device 100.

[0023] The support mechanism 34 includes a connecting member 48, a support member 50, a first arm 52, a second arm 54, and a gap adjustment mechanism 56. The connecting member 48 has a main body portion 48a extending in the third direction Z, an extending portion 48b formed by extending from one end of the main body portion 48a in the first direction X, and an extending portion 48c formed by extending from the other end of the main body portion 48a in the first direction X. The connecting member 48 rotatably supports both ends of the second rotating shaft 46 by the pair of extending portions 48b, 48c. The support member 50 is formed in a columnar shape extending in the third direction Z, and is fixed to a main body portion 48a of the connecting member 48.

[0024] The first arm 52 has an arm body 58, a bracket 60, and a rotating body 62. The arm body 58 is formed in a substantially L-shape in a side view, and is fixed to one end of the support member 50 in the third direction Z. The bracket 60 is formed in a plate shape extending in the first direction X, and is fixed to the arm body 58 with screws. The bracket 60 has a support portion 64 formed at one end in the first direction X and extending in the third direction Z. A rotating body 62 is fixed to the support portion 64. The rotating body 62 is, for example, a bearing that is rotatable around the support portion 64. The rotating body 62 is in contact with the contactor 31 of the displacement detection unit 30.

[0025] The second arm 54 is formed to extend in the first direction X, and has a connecting portion 66 and an adjustment portion 68. The connecting portion 66 is fixed to the other end of the support member 50 in the third direction Z. The adjustment portion 68 has a first adjustment surface Sa, a second adjustment surface Sb located on the opposite side of the first adjustment surface Sa, and an attachment hole H located between the first adjustment surface Sa and the second adjustment surface Sb. The first adjustment surface Sa is a plane parallel to the second adjustment surface Sb. A spring 70 is attached to the attachment hole H. The spring 70 is in a state longer than its natural length and pulls the adjustment portion 68 downward.

[0026] The gap adjustment mechanism 56 has a third motor 72, an attachment member 74, and a pressing mechanism 76. The third motor 72 is located below the adjustment unit 68 and has a motor shaft 78. An upper end 78a of the motor shaft 78 faces the first adjustment surface Sa. When the third motor 72 is driven, the motor shaft 78 moves up and down along the second direction Y. When the motor shaft 78 is pressed against the first adjustment surface Sa, a force acts on the second arm 54 in a direction that separates the second roller R2 from the first roller R1. From the above, the third motor 72 is an actuator that separates the second roller R2 from the first roller R1.

[0027] The mounting member 74 has a mounting portion 80 located at one end in the second direction Y, and a stopper ST located at the other end in the second direction. The mounting portion 80 is fixed to the frame Fr (frame Fr2) and fixes the third motor 72. The stopper ST is fixed to the frame Fr (frame Fr2) and faces the lower end 78b of the motor shaft 78. The stopper ST defines the movement range (lower limit) of the motor shaft 78.

[0028] The pressing mechanism 76 has a solenoid 82, a solenoid lever 84, and a solenoid link 86. The solenoid 82 has a housing part 82a and a movable part 82b extending from the housing part 82a in the first direction X. The housing part 82a is fixed to the frame Fr (frame Fr2) and is located below the second arm 54, the support member 50, etc. The solenoid 82 can be switched between ON and OFF, and is ON when it is energized. When the solenoid 82 is turned ON, the movable part 82b is drawn into the housing part 82a.

[0029] The solenoid lever 84 is formed in a plate shape extending in the first direction X, and one end 84a of the solenoid lever 84 is connected to the movable portion 82b of the solenoid 82. The solenoid link 86 is formed in a plate shape extending in the second direction Y, and one end 86a of the solenoid link 86 is rotatably connected to the other end 84b of the solenoid lever 84. A pivot 88 and a pressing pin 90 are provided on the other end 86b of the solenoid link 86.

[0030] The pivot 88 is formed in a columnar shape extending in the third direction Z and is rotatably supported by the frame Fr (frame Fr2). The pressing pin 90 is formed in a columnar shape extending in the opposite direction to the pivot 88 and has an outer circumferential surface facing the second adjustment surface Sb. The pressing pin 90 is located away from the pivot 88 in the first direction X. Since the pressing mechanism 76 is configured as described above, when the solenoid 82 is turned ON, the solenoid link 86 rotates about the pivot 88, and a predetermined load acts on the second adjustment surface Sb from the outer circumferential surface of the pressing pin 90. By the above operation, the pressing mechanism 76 can press the second roller R2 against the first roller R1.

[0031] The pair of frames Fr are formed to extend in the first direction X and the second direction Y. One frame Fr1 is located between the connecting member 48 and the first arm 52 in the third direction Z. The other frame Fr2 is located between the connecting member 48 and the second arm 54 in the third direction Z. A first rotating shaft 44 and a support member 50 are mounted on the pair of frames Fr. The pair of frames Fr rotatably support the first rotating shaft 44 and the support member 50.

[0032] Since the support mechanism 34 and the frame Fr are configured as described above, when a force in the second direction Y is applied to the second arm 54, the separation roller 28, the connecting member 48, the first arm 52, and the second arm 54 rotate integrally around the support member 50. At this time, the contact state between the contactor 31 of the displacement detection unit 30 and the first arm 52 (rotating body 62) is maintained, so that the displacement detection unit 30 can detect the amount of displacement of the separation roller 28 (second roller R2) based on the amount of displacement of the rotating body 62.

[0033] Next, the control configuration of the separating device 20 will be described. Fig. 5 is a block diagram showing a control configuration of the separation device 20 of the automatic ticket gate device 10 according to the embodiment. As shown in Fig. 5, the separation device 20 further includes a controller 92, a memory 94, a notification unit 96, and an operation unit 98. The controller 92 is connected to the transport mechanism 22 including the first motor 38 and the second motor 40, the thickness detection unit 24, the displacement detection unit 30, the third motor 72, the pressing mechanism 76, the memory 94, the notification unit 96, and the operation unit 98.

[0034] The controller 92 is configured as a computer equipped with a CPU (Central Processing Unit), ROM (Read-Only Memory), RAM (Random-Access Memory), etc., and controls the overall operation of the separation device 20, including the operation of each of the conveying mechanism 22, thickness detection unit 24, displacement detection unit 30, third motor 72, pressing mechanism 76, and notification unit 96, by executing a program stored in the ROM. For example, the controller 92 can drive the first motor 38, the second motor 40, etc. to transport the ticket medium P along the transport path 36.

[0035] The controller 92 can determine whether or not to perform a separation operation based on the information detected by the thickness detection unit 24, and control the rotation direction of the second motor 40. The controller 92 can perform automatic gap adjustment by driving the third motor 72, the solenoid 82, etc. at a predetermined timing, such as when starting or stopping, to automatically adjust the size of the gap G1 between the first roller R1 and the second roller R2. The controller 92 can drive the first motor 38 and the second motor 40 at a predetermined timing, such as when starting up or stopping, to perform a cleansing operation to remove dirt from the surfaces of the first roller R1 and the second roller R2.

[0036] The controller 92 can perform a detection operation to detect the amount of vibration of the second roller R2 while driving the pressing mechanism 76 (solenoid 82) to press the second roller R2 against the first roller R1 and rotate at least one of the first roller R1 and the second roller R2. In one example, the amount of vibration corresponds to the displacement of the second roller R2 in the second direction Y, and can be detected by the displacement detection unit 30. Hereinafter, the "displacement detection unit 30" will also be referred to as the "vibration detection unit 30". The controller 92 can perform the above-mentioned detection operation multiple times at any given time period. The given time period can be, for example, the period from when the power supply is turned on until the next time it is turned on, or the period from when it is turned on until it is turned off. In other words, the controller 92 can periodically perform the detection operation.

[0037] The controller 92 can store in the memory 94 the detected amount of vibration of the second roller R2. The controller 92 can create a function that indicates a prediction of a future transition of the vibration amount of the second roller R2 based on the vibration amount of the second roller R2 detected by multiple detection operations. In one example, the function is a linear function or a quadratic function. The controller 92 can predict the replacement timing of the first roller R1 and the second roller R2 based on the threshold values ​​stored in advance in the memory 94 by the operator's operation via the operation unit 98 and the created function.

[0038] The controller 92 can notify the outside of the replacement time of the first roller R1 and the second roller R2 at a timing a predetermined period before the replacement time via the notification unit 96. The predetermined period is, for example, two weeks or one month. The controller 92 can store in the memory usage status information at the installation location of the automated ticket gate device 10. The usage status information is, for example, a tendency of the number of ticket media P inserted. The controller 92 can create a function by taking into consideration the vibration amounts of the multiple second rollers R2 as well as the above-mentioned usage information.

[0039] Next, the automatic gap adjustment will be described in detail with reference to FIGS. Fig. 6 is a schematic diagram for explaining the automatic gap adjustment. Fig. 6 is a diagram showing the initial state of the automatic gap adjustment. Fig. 6 is a side view showing the second arm 54, the spring 70, the third motor 72, the mounting member 74, and the pressing mechanism 76, and the first roller R1, the second roller R2, and the connecting member 48 are shown by two-dot chain lines.

[0040] As shown in FIG. 6, in the initial state of the automatic gap adjustment, the upper end 78a of the motor shaft 78 faces the first adjustment surface Sa with a gap therebetween, and the lower end 78b of the motor shaft 78 contacts the stopper ST. The spring 70 pulls the adjustment portion 68 of the second arm 54 downward with a load F1, and urges the second roller R2 toward the first roller R1. That is, in the example shown in FIG. 6, the second roller R2 contacts the first roller R1 due to the weight of the second roller R2 and the members connected to the second roller R2, and the load F1 of the spring 70. The position of the second roller R2 at this time is defined as the first position. The solenoid 82 is OFF. At this time, when the upper end 78a of the motor shaft 78 is pressed against the first adjustment surface Sa, the second arm 54 rotates counterclockwise. Therefore, in the initial state, the position (0 point) of the upper end 78a of the motor shaft 78 when the first roller R1 and the second roller R2 are in contact with each other cannot be identified.

[0041] Fig. 7 is a schematic diagram for explaining the automatic gap adjustment following Fig. 6. Fig. 7 shows a state in which the solenoid 82 is turned on. As shown in Fig. 7, when the solenoid 82 is turned on, the solenoid link 86 rotates about the pivot 88, and the pressing pin 90 applies a load F2 to the second adjustment surface Sb of the second arm 54. That is, the second roller R2 is pressed toward the first roller R1 by the pressing pin 90. At this time, since the first roller R1 and the second roller R2 are made of rubber, the shapes of the first roller R1 and the second roller R2 are deformed, and the position of the second roller R2 is displaced to a second position lower than the first roller R1. The displacement amount d1 of the second roller R2 from the first position to the second position corresponds to the deformation amount (deflection amount) of the first roller R1 and the second roller R2.

[0042] FIG. 8 is a schematic diagram for explaining the automatic gap adjustment, following FIG. 8, the solenoid 82 is ON, and the upper end 78a of the motor shaft 78 is pressed against the first adjustment surface Sa of the second arm 54. The second arm 54 is pressed downward by the pressing mechanism 76, and therefore does not rotate even when subjected to a force from the motor shaft 78. Therefore, it is possible to determine the amount of movement of the motor shaft 78 from a state in which the lower end 78b of the motor shaft 78 is in contact with the stopper ST until the upper end 78a of the motor shaft 78 comes into contact with the first adjustment surface Sa, and by determining the amount of movement, the zero point adjustment of the motor shaft 78 is completed.

[0043] Fig. 9 is a schematic diagram for explaining the automatic gap adjustment following Fig. 8. Fig. 9 shows a state in which the solenoid 82 is turned off, and then the motor shaft 78 is moved upward, completing the automatic gap adjustment. 9, the solenoid 82 is in an OFF state, and the load F2 is not applied from the pressing mechanism 76 to the second arm 54. At this time, when the motor shaft 78 is moved upward, the connecting member 48 and the second arm 54 rotate counterclockwise about the support member 50, and the second roller R2 moves in a direction away from the first roller R1.

[0044] Therefore, the gap G1 can be set to a desired size by determining the movement amount of the motor shaft 78 according to the displacement amount d1. More specifically, the gap G1 can be set to a desired size by moving the motor shaft 78 upward from the 0 point so that the second roller R2 moves in a direction away from the first roller R1 by a distance equal to the total of the displacement amount d1 and the desired size of the gap G1 from the second position. Even in the initial state (see FIG. 6), the first roller R1 and the second roller R2 are slightly bent due to the load F1 and their own weight. The displacement amount d2 of the second roller R2 due to this bending may be calculated in advance, and the gap G1 may be set to a desired size taking the displacement amount d2 into consideration. In other words, the second roller R2 may be moved in a direction away from the first roller R1 by a distance equal to the sum of the displacement amount d1, the displacement amount d2, and the desired size of the gap G1, to set the gap G1 to a desired size.

[0045] Next, uneven wear of the first roller R1 and the second roller R2 will be described. Fig. 10 is a perspective view showing new first roller R1 and second roller R2 and worn out first roller R1 and second roller R2. Fig. 10 shows two examples of worn out items. As shown in Fig. 10, when new, the first roller R1 and the second roller R2 are cylindrical in shape. On the other hand, when worn item example 1 is in a state, the first roller R1 and the second roller R2 are roughly drum-shaped, with central portions C1 and C2 worn. Also, when worn item example 2 is in a state, the first roller R1 and the second roller R2 are elliptical cylindrical in shape.

[0046] The reason why the first roller R1 and the second roller R2 wear to the state of the wear item shown in Example 1 and Example 2 will be described. First, the reason why the first roller R1 and the second roller R2 become the state of the wear item shown in Example 1 will be described. 4, the first roller R1 faces a pair of conveying rollers Ra5 with a gap therebetween in the third direction Z. The second roller R2 faces the connecting member 48 (more specifically, the extensions 48b, 48c) with a gap therebetween in the third direction Z. That is, the first roller R1 and the second roller R2 have a degree of freedom at both ends in the third direction Z. Furthermore, the first roller R1 and the second roller R2 are made of rubber.

[0047] From the above, when multiple ticket media P are stacked and inserted into the insertion slot EN, the multiple ticket media P are inserted into the gap G1 between the first roller R1 and the second roller R2, and a load acts on the outer peripheral surfaces of the first roller R1 and the second roller R2, allowing both ends of the first roller R1 and the second roller R2 to escape to the outside. On the other hand, the central portions C1 and C2 of the first roller R1 and the second roller R2 cannot move outward because they have no freedom of movement. Therefore, depending on the number of ticket media P passing through the gap G1, the central portions C1 and C2 of the first roller R1 and the second roller R2 wear out and become in the state of Example 1 of the worn item.

[0048] Next, the reason why the first roller R1 and the second roller R2 become in the state of Example 2 of the worn items will be described. When multiple sheets of certificate media P are stacked and inserted into the insertion slot EN, the contact points of the first roller R1 and the second roller R2 change and the wear points become uneven because the total circumferential length of the first roller R1 and the second roller R2 is different from the total length of the certificate media P. Due to the unevenness of the wear points, the first roller R1 and the second roller R2 become in the state of Example 2 of the worn item.

[0049] Next, a detection operation for detecting the vibration amount of the second roller R2 will be described. First, when at least one of the first roller R1 and the second roller R2 is rotated while the second roller R2 is pressed against the first roller R1, the first roller R1 and the second roller R2 vibrate due to friction between the first roller R1 and the second roller R2. As described above, the first roller R1 and the second roller R2 wear out with repeated use. The waveform of the displacement amount of the second roller R2 when the first roller R1 and the second roller R2 are new and the waveform of the displacement amount of the second roller R2 when the first roller R1 and the second roller R2 are worn out show different characteristics. The waveform of the displacement amount of the second roller R2 will be described with reference to Figs. 11 to 14.

[0050] Fig. 11 is a diagram showing a waveform of the displacement amount of the second roller R2 when the first roller R1 and the second roller R2 are in a brand new state. Fig. 12 is a diagram showing a waveform of the displacement amount of the second roller R2 detected at a different timing from that of Fig. 11. More specifically, Fig. 12 shows a waveform of the displacement amount of the second roller R2 detected at a different time on the same day using the same automated ticket gate device 10 as Fig. 11. Fig. 13 is a diagram showing a waveform of the displacement amount of the second roller R2 when the first roller R1 and the second roller R2 are in a worn state. Fig. 14 is a diagram showing a waveform of the displacement amount detected at a different timing from that of Fig. 13. More specifically, Fig. 14 shows a waveform of the displacement amount of the second roller R2 detected at a different time on the same day using the same automated ticket gate device 10 as Fig. 13.

[0051] 11 to 14, the displacement amount on the vertical axis is a value detected by the displacement detection unit 30, and is the displacement amount in the second direction Y of the second roller R2. First, the first period T1, the second period T2, the third period T3, the fourth period T4, and the fifth period T5 shown in Fig. 11 to Fig. 14 will be described. The first period T1 is a period during which the second roller R2 is pressed against the first roller R1 with a predetermined pressing force by the pressing mechanism 76, the first roller R1 is stopped, and the second roller R2 rotates forward. Note that "forward rotation" refers to rotation in the direction in which the ticket medium P is transported in the transport direction. For example, in Fig. 2, "forward rotation" refers to "counterclockwise rotation of the first roller R1" and "clockwise rotation of the second roller R2."

[0052] The second period T2 is a period during which the second roller R2 is pressed against the first roller R1 with the same pressing force as in the first period T1, and the first roller R1 and the second roller R2 rotate forward. The third period T3 is a period during which the pressing force by the pressing mechanism 76 is reduced, and the position of the second roller R2 is raised slightly. In the third period T3, it is preferable to raise the second roller R2 until the first roller R1 and the second roller R2 are in contact with each other. The fourth period T4 is a period during which the second roller R2 is pressed against the first roller R1 with a pressing force smaller than that in the first period T1 and the second period T2 changed to the third period T3, the first roller R1 is stopped, and the second roller R2 rotates forward.

[0053] The fifth period T5 is a period during which the second roller R2 is pressed against the first roller R1 with the same pressing force as the fourth period T4, and the first roller R1 and the second roller R2 rotate forward. The sixth period T6 is a period during which the second roller R2 is pressed against the first roller R1 with the same pressing force as the fourth period T4, and the first roller R1 and the second roller R2 rotate backward. Note that "backward" means rotation in the opposite direction to forward rotation. For example, in FIG. 2, "reverse" means "clockwise rotation of the first roller R1" and "counterclockwise rotation of the second roller R2". In one example, the time length of each of the first period T1, the second period T2, the third period T3, the fourth period T4, the fifth period T5, and the sixth period T6 is about 1 second.

[0054] 11 and 12, when the first roller R1 and the second roller R2 are brand new and detection operations are performed at different times, the vibration amounts in the waveforms of the detected displacement amounts of the second roller R2 are different. Note that the vibration amount refers to the amplitude. The same is true when the first roller R1 and the second roller R2 are in a worn state, and as shown in Figures 13 and 14, when the detection operation is performed at different timings, the detected vibration amount differs. In summary, even when detecting the amount of vibration using the same aircraft at the same time, there will be slight variations in the detected values, so in order to detect the amount of vibration more accurately, it is preferable to perform the detection operation multiple times on the same day.

[0055] As shown in FIGS. 11 and 13, when the first roller R1 and the second roller R2 are worn parts, the vibration amount in the waveform of the displacement amount of the second roller R2 is larger than when the first roller R1 and the second roller R2 are new. The reason why the magnitude of vibration differs between new and worn items as described above will be explained below. When the first roller R1 and the second roller R2 are unevenly worn (see FIG. 10), the contact area between the first roller R1 and the second roller R2 becomes smaller compared to when the first roller R1 and the second roller R2 are new.

[0056] On the other hand, when the pressing force by the pressing mechanism 76 is the same in a new state and in a worn state, the smaller the contact area between the first roller R1 and the second roller R2, the greater the stress caused by the pressing force, according to the relationship between area and force. The greater the stress, the greater the vibration amount of the first roller R1 and the second roller R2 caused by friction. Therefore, when the first roller R1 and the second roller R2 are in a worn state, the vibration amount detected from the waveform of the displacement amount of the second roller R2 is greater than when the first roller R1 and the second roller R2 are in a new state.

[0057] In the example shown in Fig. 11 to Fig. 14, when the first roller R1 rotates forward or backward, the rotation speed of the first roller R1 is about 4 rpm, and when the second roller R2 rotates forward or backward, the rotation speed of the second roller R2 is about 18 rpm. The above-mentioned rotation speeds are the rotation speeds used during the cleansing operation of the first roller R1 and the second roller R2. As described above, when the rotation speed of the first roller R1 and the rotation speed of the second roller R2 are different, the effect of friction between the first roller R1 and the second roller R2 is more easily detected than when the rotation speed of the first roller R1 and the rotation speed of the second roller R2 are the same.

[0058] In Figures 11 to 14, the roller rotation patterns for the detection operation are shown as one roller rotating forward and the other roller stopped, both rollers rotating forward, and both rollers rotating reverse. However, it is also possible to detect patterns where one roller rotates forward and the other roller rotates reverse, or one roller rotates reverse and the other roller is stopped. Using the above method, the controller 92 can set the rotation speed and rotation direction of the first roller R1 and the second roller R2 to the desired state by controlling the conveying mechanism 22, and can set the pressing force from the second roller R2 to the first roller R1 to the desired magnitude by controlling the pressing mechanism 76, and can detect the vibration amount of the second roller R2 under various conditions with the displacement detection unit (vibration detection unit) 30.

[0059] 10 shows two abnormal wear patterns, Example 1 and Example 2. Differences in the waveform of the displacement amount of the second roller R2 depending on the abnormal wear pattern will be described. Fig. 15 is a diagram showing an example of the displacement amount of the second roller R2 when the first roller R1 and the second roller R2 are in the state of wear item example 1. Fig. 16 is a diagram showing an example of the displacement amount of the second roller R2 when the first roller R1 and the second roller R2 are in the state of wear item example 2. Fig. 17 is a diagram showing an example of the displacement amount of the second roller R2 when the first roller R1 and the second roller R2 include elements of both wear item example 1 and example 2.

[0060] 15 and 16, the displacement amount of the upwardly protruding convex portion B and the downwardly protruding concave portion D is approximately constant. In one example, the displacement amount of the convex portion B is approximately the same as the displacement amount of the adjacent convex portion B. The displacement amount of the concave portion D is approximately the same as the displacement amount of the adjacent concave portion D. The wavelength of the vibration of the second roller R2 when the first roller R1 and the second roller R2 are in the state of wear item example 1 is shorter than the wavelength of the vibration of the second roller R2 when the first roller R1 and the second roller R2 are in the state of wear item example 2. From the above, whether the first roller R1 and the second roller R2 are the wear items (Example 1 or Example 2) can be determined based on the wavelength of the vibration amount.

[0061] 17, when the first roller R1 and the second roller R2 include elements of both the wear items of Example 1 and Example 2, the displacement amount of the convex portion B and the displacement amount of the concave portion D are not constant. In one example, the displacement amount of the convex portion B is different from the displacement amount of the adjacent convex portion B. The displacement amount of the concave portion D is different from the displacement amount of the adjacent concave portion D. From the above, it can be determined that when the convex portion B and the concave portion D are not constant, the first roller R1 and the second roller R2 include elements of both Example 1 and Example 2 of the wear item.

[0062] Next, a function indicating a prediction of future changes in the vibration amount of the second roller R2 will be described. Fig. 18 is a diagram showing the relationship between the operating time of the automated ticket gate device 10 and the vibration amount of the second roller R2. In Fig. 18, the detection value DE of the vibration amount obtained by the detection operation is shown by a solid line, and a function F equivalent to a prediction of the transition of the vibration amount is shown by a dashed line. As shown in Fig. 18, the detection value DE is the vibration amount of the second roller R2 calculated based on the waveform (see Figs. 11 to 14) of the displacement amount of the second roller R2 detected in the detection operation until 20 months have passed since the first roller R1 and the second roller R2 were brand new. In one example, the average value of the vibration amount detected in the second period T2 is plotted as the detection value DE. Note that the detection value DE does not have to be the vibration amount in the second period T2. Furthermore, the detection value DE is not limited to being the average value of the vibration amount, and may be, for example, a median value or a maximum value.

[0063] The function F is a curve created by approximating the detection value DE. In one example, the function F is a quadratic function. The function F exists even in a period in which the detection value DE does not exist. In the example shown in FIG. 18, the function F exists in a prediction period from 20 months onwards. The function F in the prediction period corresponds to a prediction of a future change in the vibration amount of the second roller R2. The function F may be a linear function, and the controller 92 may determine whether the function F is a linear function or a quadratic function each time the controller 92 stores the detection value DE in the memory 94.

[0064] The threshold value Th corresponds to a value of the vibration amount of the second roller R2 at which the first roller R1 and the second roller R2 should be replaced. For example, when the vibration amount of the second roller R2 reaches the threshold value Th, the accuracy of the separation operation by the first roller R1 and the second roller R2 becomes equal to or lower than a desired accuracy. In one example, the threshold value Th is set to 100 μm. Hereinafter, the time when the function F reaches the threshold value Th is referred to as a replacement time RT1. Also, the period from a time a predetermined period before the replacement time RT1 to a time a predetermined period has passed is referred to as a replacement period RT2.

[0065] From the above, the automatic ticket gate device 10 can calculate the replacement timing RT1 and the replacement period RT2 based on the function F and the threshold value Th. The calculated replacement time RT1 and replacement period RT2 are notified to the outside via the notification unit 96 (see FIG. 5) at a timing (notification time NT) a predetermined period before. The above-mentioned outside is, for example, the manufacturer, manager, or user of the automatic ticket gate device 10. The notification unit 96 may also notify the outside of the function F. The notification unit 96 may also sound an alarm when the replacement time RT1 approaches.

[0066] Next, the usage status information will be described. Fig. 19 is a diagram showing an example of the usage status of the installation location of the automated ticket gate device 10. Fig. 19 shows the relationship between the operation time of the automated ticket gate device 10 and the number of ticket media P passing through the gap between the first roller R1 and the second roller R2. 19, the number of passing sheets of the certificate medium P during the period when the operating time is from 2 to 4 months and the period when the operating time is from 14 to 16 months is smaller than the number of passing sheets of the certificate medium P during the period when the operating time is from 6 to 10 months. The number of passing sheets of the certificate medium P is the largest when the operating time is 8 months.

[0067] 18, the rate of increase in the detection value DE varies depending on the time period. For example, the rate of increase in the period when the operating time is from 2 months to 4 months and the rate of increase in the period when the operating time is from 14 months to 16 months are lower than the rate of increase in the period when the operating time is from 6 months to 10 months. 18 and 19 are values ​​detected at the same time for the same automated ticket gate device 10, it can be seen that there is a correlation between the usage status of the automated ticket gate device 10 (more specifically, the number of ticket media P passing through) and the change in the amount of vibration over time. More specifically, when the number of ticket media P passing through is large, the rate of increase in the amount of vibration of the second roller R2 increases, and when the number of ticket media P passing through is small, the rate of increase in the amount of vibration of the second roller R2 decreases.

[0068] On the other hand, if we assume that the cycle of the number of passing sheets of the certificate medium P is 12 months, it can be predicted that the number of passing sheets of the certificate medium P will be large when the operating time is between 18 and 22 months. Considering the above correlation, it can be predicted that the rate of increase in the vibration amount of the second roller R2 will be high when the operating time is between 18 and 22 months. In the automatic ticket gate device 10 of this embodiment, the function F is not limited to being created by taking into consideration only the vibration amount (detection value DE) of the second roller R2, but the function F may also be created by taking into consideration the above-mentioned usage status information and information obtained by correlation.

[0069] In summary, in the automatic ticket gate device 10 of this embodiment, the controller 92 acquires different usage information for each installation location, learns the trends in the usage information and the correlation with the vibration amount of the second roller R2, and creates the function F taking into account the learned correlation. 19 describes the usage status information regarding the number of passing sheets of the ticket medium P on a monthly basis, but the usage status information may be information regarding the number of passing sheets of the ticket medium P on a daily basis or information regarding the number of passing sheets of the ticket medium P on a weekly basis. By acquiring information regarding the number of passing sheets of the ticket medium P on a daily basis, the controller 92 can learn trends, such as the number of passing sheets on holidays being greater than the number of passing sheets on weekdays.

[0070] Next, the process of calculating the replacement time RT1 will be described. FIG. 20 is a flowchart showing an example of a process for calculating the replacement time RT1. 20, when processing is started, first, the controller 92 turns on the power of the automated ticket gate device 10 based on an instruction from the operator via the operation unit 98 (S1). Next, the controller 92 drives the pressing mechanism 76 (solenoid 82), the transport mechanism 22 (first motor 38, second motor 40), and the displacement detection unit (vibration detection unit) 30 to perform detection operations (S2), and stores the detected vibration amount of the second roller R2 in the memory 94 (S3).

[0071] Next, the controller 92 determines whether the future change in the vibration amount of the second roller R2 will be a linear function or a quadratic function based on the vibration amount stored in the memory 94 (in one example, the detection value DE in FIG. 18) (S4), and creates a function F based on the above determination (S5). Next, the controller 92 calculates the replacement time RT1 based on a threshold value Th previously stored in the memory 94 and the function F (S6), and determines whether the current time is a predetermined period before the replacement time (notification time NT) or not (S7).

[0072] If the current time has passed the notification time NT (S7), the controller 92 notifies the outside via the notification unit 96 of information on the replacement time RT1 (S8), and controls the pressing mechanism 76 and the transport mechanism 22 to perform automatic gap adjustment and cleansing operations (S9). On the other hand, if the current time has not passed the notification time NT (S7), the controller 92 executes step S9 without executing step S8. After executing step S9, the controller 92 determines whether or not to turn off the power to the automated ticket gate device 10 (S10), and if the power is to be turned off, executes steps S1 to S10 again. If the power to the automated ticket gate device 10 is not to be turned off (S10), the process of calculating the replacement time RT1 is terminated.

[0073] As described above, the automated ticket gate device 10 of this embodiment can create the function F by taking into account the vibration amount of the second roller R2 and the usage status information. Using Fig. 20 as an example of a process that takes into account the usage status information, in step S3, the controller 92 associates the vibration amount of the second roller R2 with the usage status information and stores it in the memory 94, and learns the correlation between the vibration amount and the usage status information. In step S5, the controller 92 creates the function F based on the vibration amount of the second roller R2 and the correlation. In step S8, the controller 92 may also notify the function F, the replacement period RT2, and the like to the outside.

[0074] The effects of this embodiment will be described below. According to the conveying device and automatic ticket gate device 10 of this embodiment, the conveying device includes a vibration detection unit 30 that detects the vibration amount of the second roller R2, a memory 94 that stores the vibration amount of the second roller R2, and a controller 92 that executes a detection operation and creates a function F based on the detected vibration amount. This makes it possible to detect the amount of vibration caused by friction changes according to wear, manage the wear amount of the first roller R1 and the second roller R2, and obtain a highly reliable conveying device.

[0075] The memory 94 stores a threshold value Th, and the controller 92 calculates the replacement time RT1 based on the threshold value Th and a function F. In addition, the controller 92 notifies the outside via the notification unit 96 of information on the replacement time RT1 at a timing prior to the replacement time RT1. This allows the first roller R1 and the second roller R2 to be replaced with new ones before malfunctions caused by wear of the first roller R1 and the second roller R2, such as ticket jamming, occur, thereby improving the operating rate of the automatic ticket gate device 10.

[0076] The controller 92 determines whether the function is a linear function or a quadratic function each time the vibration amount of the second roller R2 is stored in the memory 94. The controller 92 also associates the vibration amount of the second roller R2 with usage status information and stores it in the memory 94, learns the correlation between the vibration amount and the usage status information, and creates a function F based on the vibration amount and the usage status information. This makes it possible to improve the accuracy of the function F and to detect the replacement time RT1 more accurately.
