However, when a folded banknote or a wrinkled banknote (hereinafter referred to as a worn-out banknote) is wound around the winding drum 113, the winding diameter of the winding drum 113 may become equal to or larger than an expected winding diameter. In such a case, as illustrated in
According to an aspect of the embodiments, a paper sheet storage device includes: a supply reel that supplies a rolled belt-like member; a winding drum around which a paper sheet is wound together with the belt-like member supplied from the supply reel; a first detection unit that detects a supply amount of the belt-like member supplied from the supply reel; and a second detection unit that detects the winding drum of which the outer diameter becomes equal to or larger than a predetermined outer diameter when the paper sheet is wound around the winding drum together with the belt-like member.
The object and advantages of the invention will be realized and attained by means of the elements and combinations particularly pointed out in the claims.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are not restrictive of the invention.
Hereinafter, a banknote storage device and a banknote storage method according to an embodiment, related to a paper sheet storage device and a paper sheet storage method disclosed in the present application will be described in detail based on the drawings. The paper sheet storage device and the paper sheet storage method disclosed in the present application are not limited to the following embodiments.
First Embodiment
[Configuration of Banknote Handling Device]
[Configuration of Banknote Storage Device]
As illustrated in
In the first embodiment, although the narrow tape 14 is used as an example of the belt-like member, the belt-like member is not limited to the tape. Moreover, in the embodiment, although the tape 14 formed of a resin film is used, the tape 14 is not limited to this but a tape formed of other material may be used as appropriate.
The banknote storage device 11 includes a plurality of guide rollers 18 disposed between the supply reel 12 and the winding drum 13. The plurality of guide rollers 18 forms a conveying path, along which the tape 14 supplied from the supply reel 12 is conveyed to the winding drum 13. The guide roller 18 is rotatably supported by a spindle 18a.
As illustrated in
The supply reel 12 is supported by a rotating shaft 25, and as illustrated in
The tape 14 is formed of a resin film having a light transmitting property and has, for example, a thickness of approximately 0.1 mm and a width of approximately 20 mm. As illustrated in
Although not illustrated in the drawings, a spring mechanism including a torsion spring that applies tension to the tape 14, is incorporated into the supply reel 12. Moreover, a torque limiter for making the tension applied to the tape 14 constant, is provided in the rotating shaft 25 of the supply reel 12.
As illustrated in
The winding drum 13 is supported by a rotating shaft 26 and is rotated by a driving motor (not illustrated) included in the driving mechanism 28. Moreover, the rotation direction of the driving motor of the driving mechanism 28 is switched between a normal direction and a reverse direction by the control unit 29, whereby the driving motor of the driving mechanism 28 selectively rotates the rotating shaft 25 of the supply reel 12 or the rotating shaft 26 of the winding drum 13 using a transmission mechanism of the driving mechanism 28.
[Configuration of First Detection Unit and Detection of End of Tape]
The first detection unit 16 is disposed near the conveying path of the tape 14 drawn from the supply reel 12, and an optical sensor is used as the first detection unit 16. The optical sensor as the first detection unit 16 has a light emitting unit 16a, which emits detection light, and a light receiving unit 16b, which receives the detection light emitted by the light emitting unit 16a. As illustrated in
In the first detection unit 16, the starting end 32 and the terminal end 33 of the tape 14 move between the light emitting unit 16a and the light receiving unit 16b with a winding operation of the supply reel 12 or the winding drum 13 winding the tape 14. In this case, since the intermediate portion in the longitudinal direction (the direction A) of the tape 14 does not block the detection light emitted by the light emitting unit 16a, a state, in which the light receiving unit 16b receives the detection light, is created. On the other hand, since the starting end 32 and the terminal end 33 of the tape 14 block the detection light emitted by the light emitting unit 16a, a state, in which the detection light is not received by the light receiving unit 16b, is created. Therefore, the light receiving unit 16b detects the positions of the starting end 32 and the terminal end 33 of the tape 14 when the state, in which the detection light is received, is changed to the state, in which the detection light is not received.
Upon detecting the starting end 32 of the tape 14, the first detection unit 16 transmits a detection signal to the control unit 29. Similarly, upon detecting the terminal end 33 of the tape 14, the first detection unit 16 transmits a detection signal to the control unit 29. Based on a detection signal of the terminal end 33 from the first detection unit 16, the control unit 29 stops the driving motor and stops the winding operation of the winding drum 13.
In this manner, when the first detection unit 16 detects both ends of the tape 14 supplied from the supply reel 12, the control unit 29 calculates a supply amount of the tape 14 (that is, the winding amount of the tape 14 wound by the winding drum 13). The control unit 29 performs a predetermined calculation process based on the winding amount of the tape 14 to count the number of banknotes 2 stored in a state of being wound around the winding drum 13.
In the present embodiment, although the starting end 32 and the terminal end 33 of the tape 14 have a light blocking property and the intermediate portion of the tape 14 has a light transmitting property, the tape 14 is not limited to this configuration. Contrary to this configuration, the starting end 32 and the terminal end 33 of the tape 14 may have a light transmitting property, and the intermediate portion of the tape 14 may have a light blocking property. In this case, it is also possible to detect the starting end and the terminal end similarly to the present embodiment. Moreover, a reflection sheet may be used instead of the light blocking film formed on the starting end 32 and the terminal end 33 of the tape 14.
In the present embodiment, although the first detection unit 16 is configured using an optical sensor, a rotary encoder, which detects a rotation amount of the rotating shafts 25 and 26 of the supply reel 12 and the winding drum 13, may be used.
[Configuration of Second Detection Unit and Detection of Winding Diameter of Winding Drum]
As illustrated in
As illustrated in
The detection lever 36 is disposed at a predetermined attitude around the spindle 36c so that the contactor 36a makes contact with the winding drum 13 of which the outer diameter becomes equal to a predetermined winding diameter. When the detection lever 36 is at an initial position, which is the predetermined attitude, the contactor 36a is separated from the winding drum 13 in a radial direction of the winding drum 13. When the diameter of the winding drum 13 becomes equal to or larger than the predetermined winding diameter, the contactor 36a makes contact with the tape 14 wound around the winding drum 13. In this way, the contact between the tape 14 and the detection lever 36 is suppressed as much as possible to prevent wearing and damage of the detection lever 36 and the tape 14 to enhance durability. Moreover, the detection lever 36 is biased around the spindle 36c by a torsion spring (not illustrated) so that the contactor 36a returns to the initial position.
As illustrated in
The predetermined winding diameter of the winding drum 13 is set to such a diameter (outer diameter) that the winding drum 13 does not interfere with other constituent members such as the guide member 23 disposed inside the banknote storage device 11. Particularly, in the present embodiment, the predetermined winding diameter is set to such a diameter that the winding drum 13, around which the banknotes 2 are wound, does not interfere with the conveying path of the tape 14 supplied from the supply reel 12.
The second detection unit 17 transmits a detection signal to the control unit 29 upon detecting the winding drum 13 of which the outer diameter becomes equal to or larger than a predetermined winding diameter when the contactor 36a of the detection lever 36 makes contact with the tape 14 wound around the winding drum 13. Based on the detection signal from the second detection unit 17, the control unit 29 stops the driving motor and stops the winding operation of the winding drum 13.
In the banknote storage device 11, when such a worn-out banknote, as described in the related art, is wound around the winding drum 13, the winding diameter of the winding drum 13 may become equal to or larger than an expected winding diameter. In such a case, according to the second detection unit 17, it is possible to stop the winding operation before the winding drum 13 interferes with the conveying path of the tape 14 or another constituent member such as the guide member 23. In this way, it is possible to prevent damage and breakage of the winding drum 13 or the other constituent member to improve the reliability of the winding operation.
Although the second detection unit 17 uses an optical sensor to detect the movement of the detection lever 36, the second detection unit 17 is not limited to the configuration in which the optical sensor is used. The second detection unit 17 may only need to have a configuration that detects the movement of the detection lever 36, and a pressure sensor or a press button switch, that is pressed by the detection lever 36 that moves, may be used. Moreover, a configuration, in which the light emitting unit and the light receiving unit of the optical sensor are disposed at an interval in an axial direction (the direction F) of the winding drum 13 so that the optical axis of the detection light passes through the position of the contactor 36a of the detection lever 36 at the initial position, may be employed. According to this configuration, it is possible to optically detect the winding drum 13 of which the outer diameter becomes equal to or larger than the predetermined outer diameter.
[Banknote Storage Operation]
An operation of winding the banknotes 2 around the winding drum 13 together with the tape 14 in the banknote storage device 11, which has such a configuration, will be described.
In
Subsequently, when the first detection unit 16 detects the terminal end 33 of the tape 14 or the second detection unit 17 detects the winding drum 13 of which the outer diameter becomes equal to or larger than the predetermined outer diameter, the rotation of the winding drum 13 is stopped by the control unit 29. In this way, the winding drum 13 ends the operation of storing the banknotes 2.
On the other hand, after the driving of the winding drum 13 stops, the control unit 29 switches the rotation direction of the driving motor of the driving mechanism 28 whereby the supply reel 12 is rotated by the driving motor. In
The banknote storage method in the banknote storage device 11 of the first embodiment includes a storing step, a first detection step, and a second detection step. In the storing step, the banknotes 2 are wound around the winding drum 13 together with the tape 14 supplied from the supply reel 12 around which the tape 14 is rolled. In the first detection step, the supply amount of the tape 14 supplied from the supply reel 12 is detected. In the second detection step, the winding drum 13, of which the outer diameter becomes equal to or larger than the predetermined outer diameter, is detected.
[Control Based on First and Second Detection Units]
As illustrated in
In the banknote storage device 11, after the first detection unit 16 detects the starting end 32 of the tape 14, the banknotes 2, loaded from the conveying port 21, are wound around the winding drum 13 together with the tape 14, whereby storing of the banknotes 2 starts. There is a possibility that during the operation of winding the tape 14 and the banknotes 2, the diameter of the winding drum 13 becomes equal to or larger than the predetermined winding diameter. Due to this, the control unit 29 determines whether the second detection unit 17 has detected the winding drum 13 of which the outer diameter becomes equal to or larger than the predetermined outer diameter during the winding operation (step S2). In step S2, when the second detection unit 17 has detected the winding drum 13, of which the outer diameter becomes equal to or larger than the predetermined outer diameter, the flow proceeds to step S4 to be described later, and the control unit 29 stops the driving motor of the driving mechanism 28. On the other hand, in step S2, when the second detection unit 17 has not detected the winding drum 13, of which the outer diameter becomes equal to or larger than the predetermined outer diameter, the winding operation of the winding drum 13 is continued and the flow proceeds to step S3.
Subsequently, the control unit 29 determines whether the first detection unit 16 has not detected the terminal end 33 of the tape 14 (step S3). In step S3, when the first detection unit 16 has not detected the terminal end 33 of the tape 14, the winding drum 13 continues the operation of winding the tape 14 and the banknotes 2, and the flow returns to step S2. On the other hand, in step S3, when the first detection unit 16 has detected the terminal end 33 of the tape 14, the flow proceeds to step S4, and the control unit 29 stops the driving motor of the driving mechanism 28. In this way, the control unit 29 stops the winding operation of the winding drum 13 (step S4).
[Effects of First Embodiment]
The banknote storage device 11 of the first embodiment includes the supply reel 12, the winding drum 13 around which the banknotes 2 are wound together with the tape 14, the first detection unit 16 that detects the supply amount of the tape 14, and the second detection unit 17 that detects the winding drum 13 of which the outer diameter becomes equal to or larger than the predetermined outer diameter. In this way, the banknote storage device 11 can detect, with the aid of the second detection unit 17, that the diameter of the winding drum 13 becomes equal to or larger than the predetermined outer diameter during the winding operation when a worn-out banknote is wound around the winding drum 13, for example. Therefore, according to the banknote storage device 11, it is possible to prevent the winding drum 13 from interfering with the conveying path of the tape 14 or other constituent members during the winding operation and to prevent damage and breakage of the tape 14, the winding drum 13, and other constituent members. As a result, it is possible to improve the reliability of the winding operation of the winding drum 13.
The second detection unit 17 of the first embodiment includes the detection lever 36 that moves in contact with the winding drum 13 of which the outer diameter becomes equal to or larger than the predetermined outer diameter and the optical sensor 37 that detects the movement of the detection lever 36. In this way, it is possible to detect the winding diameter of the winding drum 13 with a simple configuration and is possible to suppress an increase in the manufacturing cost of the banknote storage device 11.
The detection lever 36 of the second detection unit 17 of the first embodiment is disposed to be separated from the winding drum 13 in the radial direction (the direction D) of the winding drum 13 so as to make contact with the winding drum 13 when the diameter of the winding drum 13 has become equal to or larger than the predetermined outer diameter. In this way, it is possible to suppress the contact between the detection lever 36 and the winding drum 13 as much as possible and is possible to prevent wearing and damage of the detection lever 36 and the tape 14.
In the first embodiment, the conveying path of the tape 14, conveyed from the supply reel 12 to the winding drum 13, passes near the outer diameter of the winding drum 13 around which the tape 14, supplied from the supply reel 12, is wound up to the terminal end 33 in the longitudinal direction (the direction A). Particularly, in a structure in which the size of the conveying path of the tape 14 is reduced, the presence of the second detection unit 17 is highly effective in preventing interference between the winding drum 13 and the conveying path of the tape 14. However, the conveying path of the tape 14 is not limited to such a configuration as illustrated in the first embodiment.
Hereinafter, other embodiments will be described with reference to the drawings. In the other embodiments, the same constituent members, as those of the first embodiment, will be denoted by the same reference numerals as those used in the first embodiment, and the description thereof will not be provided.
Second Embodiment
As illustrated in
In the detection lever 46 according to the second embodiment, the detection piece 46b, as detected the movement by the first detection unit 16, extends up to the vicinity of a position between the light emitting unit 16a and the light receiving unit 16b. The detection piece 46b is disposed such a position that the detection piece 46b does not make contact with the tape 14. Moreover, the detection piece 46b is formed between the light emitting unit 16a and the light receiving unit 16b so that, when the contactor 46a makes contact with the winding drum 13 and the detection lever 46 is moved, the detection piece 46b enters between the light emitting unit 16a and the conveying path of the tape 14.
[Effects of Second Embodiment]
The first detection unit 16 of the second embodiment uses an optical sensor that optically detects an end in the longitudinal direction (the direction A) of the tape 14. The optical sensor of the first detection unit 16 is the same member as the optical sensor 37 of the second detection unit 17. That is, the movement of the detection lever 46 of the second detection unit 17 is detected using the light emitting unit 16a and the light receiving unit 16b of the first detection unit 16. In this way, since the first detection unit 16 also serves as the optical sensor 37 of the second detection unit 17, the optical sensor is shared, and the optical sensor 37 of the second detection unit 17 of the first embodiment can be omitted. As a result, according to the second embodiment, it is possible to simplify the configuration of the second detection unit 17, to reduce the manufacturing cost, and to reduce the size of the entire banknote storage device 11. Moreover, in the second embodiment, it is possible to prevent damage and breakage of the tape 14, the winding drum 13, and the like and to improve the reliability of the winding operation of the winding drum 13 similarly to the first embodiment.
Third Embodiment
As illustrated in
[Effects of Third Embodiment]
For example, when the circumferential surface of the winding drum 13 is inclined in an axial direction (the direction F) due to an inclination or the like of the rotating shaft 26 of the winding drum 13, the winding diameter of the winding drum 13 is biased in the axial direction (the direction F) of the winding drum 13. In such a case, at least one of the contactors 36a of the plurality of detection levers 36 makes contact with the tape 14 wound around the winding drum 13 whereby the winding drum 13, of which the outer diameter becomes equal to or larger than the predetermined outer diameter, can be detected. Due to this, according to the third embodiment, it is possible to improve the detection accuracy of the winding diameter of the winding drum 13. Therefore, in the third embodiment, it is possible to prevent damage and breakage of the tape 14, the winding drum 13, and the like and to improve the reliability of the winding operation of the winding drum 13 similarly to the first and second embodiments.
Fourth Embodiment
As illustrated in
The detection lever 56 has a plurality of contactors 56a, which makes contact with the tape 14 wound around the winding drum 13, and a detection piece 56b which is detected by an optical sensor 57, and the detection lever 56 is rotatably supported by a spindle 56c. Moreover, the detection lever 56 is biased around the spindle 56c by a torsion spring (not illustrated) so that the plurality of contactors 56a returns to an initial position.
The contactors 56a of the detection lever 56 are disposed at an interval along the width direction (the direction C) of the tape 14 wound around the winding drum 13. Due to this, the detection lever 56 detects the winding drum 13 of which the outer diameter becomes equal to or larger than the predetermined outer diameter when at least one of the plurality of contactors 56a makes contact with the tape 14 wound around the winding drum 13.
[Effects of Fourth Embodiment]
The detection lever 56 of the second detection unit 55 according to the fourth embodiment has the plurality of contactors 56a that makes contact with the winding drum 13, and the plurality of contactors 56a is disposed along the width direction (the direction C) of the tape 14 wound around the winding drum 13. Due to this, it is possible to cope with a case in which the winding diameter of the winding drum 13 is biased in the axial direction (the direction F) of the winding drum 13. That is, in such a case, it is possible to detect the winding drum 13 of which the outer diameter becomes equal to or larger than the predetermined outer diameter when at least one of the contactors 56a of the plurality of detection levers 56 makes contact with the tape 14 wound around the winding drum 13. Due to this, according to the fourth embodiment, it is possible to improve the detection accuracy of the winding diameter of the winding drum 13 similarly to the third embodiment. Therefore, in the fourth embodiment, it is possible to prevent damage and breakage of the tape 14, the winding drum 13, and the like, and to improve the reliability of the winding operation of the winding drum 13 similarly to the first, second, and third embodiments.
Although not illustrated in the drawings, a configuration, in which a plurality of detection levers each having a plurality of contactors is disposed in the width direction (the direction C) of the tape 14 wound around the winding drum 13, may be employed as appropriate. Moreover, although the detection lever of the embodiment is disposed at such a position as to make contact with the tape 14 wound around the winding drum 13, the detection lever may be disposed so as to make contact with the banknote 2 wound around the winding drum 13 as appropriate. However, a configuration, in which the detection lever makes contact with the tape 14, is preferable from the perspective of preventing damage and breakage of the banknotes 2.
The present embodiment may be applied to a configuration in which banknotes are wound around the winding drum together with two tapes while the banknotes are sandwiched between the facing tapes supplied from two supply reels. Moreover, the present embodiment may be applied to a configuration in which banknotes are wound around the winding drum together with a plurality of tapes arranged in parallel in the axial direction (the direction F) of the winding drum.
According to an aspect of the paper sheet storage device disclosed in the present application, it is possible to prevent breakage of a winding drum and the other constituent members and increase the reliability of a winding operation of the winding drum.
