Description

Paper sheet storage and dispensing apparatus

Technical Field

The present invention relates to a paper sheet storage and dispensing apparatus which stores and dispenses paper sheets by winding and unwinding a tape.

Background

Paper sheet storage and dispensing devices have been developed for use in banknote processors and the like, having: a first reel drum on which the tape is wound from one side thereof; and a second reel drum that rolls the tape on the sheet of paper while the tape is wound thereon from the other side. In such a sheet storing and dispensing apparatus, when the second reel drum is rotated in one direction, a sheet of paper is wound around the second reel drum together with the tape and stored thereon, and when the second reel drum is rotated in the opposite direction, the sheet of paper stored on the second reel drum is fed out together with the tape.

For example, japanese patent laying-open No.3534966 discloses a technique in which in a paper sheet storing and dispensing apparatus using tapes for storing and dispensing paper sheets as described above, any slack of the tapes is restricted, and the winding speed can be changed depending on the number of tape windings.

However, in the aforementioned paper sheet storage and dispensing apparatus, the transfer speed of the tape is estimated from the outer peripheral diameter of the tape wound on the drum, and is changed depending on the number of windings of the tape around the drum and the number of windings of the paper sheets around the drum. Accordingly, it is impossible to accurately measure the transport speed of the tape. For this reason, it is difficult to keep the transport speed of the belt at an accurate, predetermined constant speed, and it is impossible to obtain sheets from the inlet/outlet at proper fixed time intervals. As a result, it is impossible to supply the sheet to the outside through the inlet/outlet at appropriate fixed time intervals.

According to a paper sheet storing and dispensing apparatus of a first aspect of the present invention, paper sheets are stored and dispensed, and the apparatus includes: a first reel drum around which the tape is wound from one side thereof; a second reel drum on which the paper sheets are stored by winding the tape from the other side of the tape in a state in which the paper sheets supplied from the external paper sheet conveying section to the inlet/outlet and the tape are overlapped with each other; a motor for driving the first reel drum and the second reel drum by a driving system; an electromagnetic clutch that switches between transmitting and interrupting the driving force from the drive system; an electromagnetic brake that applies braking to the drive system; a trigger sensor that detects the supply of the sheet from the sheet transport portion to the inlet/outlet; a tape speed detecting section that detects a transport speed of the tape at the entrance/exit; a motor speed variation control unit which controls variation of a rotational speed of the motor; a winding control unit which causes a winding operation by controlling the electromagnetic clutch so as to transmit a driving force of the motor when the trigger sensor detects that the paper sheet is supplied to the inlet/outlet, the winding operation being an operation in which the tape is dispensed from the first reel drum when the tape is wound on the second reel drum so that the paper sheet supplied to the inlet/outlet is wound on the second reel drum, and the winding control unit controls the motor speed variation control unit so that a tape transmission speed detected by the tape speed detection unit is maintained at a fixed speed which is faster by a predetermined amount than a transmission speed of the paper sheet transmission portion during the winding operation.

According to the above-described structure, the tape speed detecting section detects the conveyance speed of the tape at the entrance/exit. For this reason, it is possible to easily and accurately measure the transport speed of the tape. In addition, during a winding operation that is started when the trigger sensor detects that the paper sheet is supplied to the inlet/outlet, the winding control unit controls the motor speed variation control unit so that the belt conveyance speed detected by the belt speed detection unit is maintained at a fixed speed that is faster than the conveyance speed of the paper sheet conveyance section by a predetermined amount. For this reason, the sheet supplied from the sheet conveying portion can be safely sucked.

According to the above-described structure, the tape speed detecting section detects the conveyance speed of the tape at the entrance/exit. For this reason, the transport speed of the tape can be easily and accurately measured. Further, during the unwinding operation, the unwinding control unit controls the motor speed variation control unit so that the belt conveyance speed detected by the belt speed detection unit is maintained at a fixed speed that is slower by a predetermined amount than the conveyance speed of the paper sheet conveying section. For this reason, the paper sheets to be dispensed to the paper sheet conveying portion can be securely conveyed to the paper sheet conveying portion.

According to the above-described structure, the tape speed detecting section detects the conveyance speed of the tape at the entrance/exit. For this reason, the transport speed of the tape can be easily and accurately measured. In addition, during a winding operation that starts when the paper sheet is detected by the trigger sensor to be supplied to the inlet/outlet, the winding control unit controls the motor speed variation control unit so that the belt conveyance speed detected by the belt speed detection unit is maintained at a fixed speed that is faster than the conveyance speed of the paper sheet conveyance section by a predetermined amount. For this reason, the sheet supplied from the sheet conveying portion can be safely sucked. In addition, in the unwinding operation, the unwinding control unit controls the motor speed variation control unit so that the belt conveyance speed detected by the belt speed detection unit is maintained at a fixed speed that is slower by a predetermined amount than the conveyance speed of the paper sheet conveying section. For this reason, the sheet dispensed to the sheet transport portion can be securely conveyed to the sheet transport portion.

In the paper sheet storing and dispensing apparatus according to the first to third aspects of the present invention described above, the belt speed detecting portion may be provided on a feed roller that is provided at the entrance/exit and overlaps the belt and the paper sheets with each other.

According to the above configuration, since the belt speed detecting portion is provided on the feeding roller which is provided at the entrance/exit and overlaps the belt and the paper sheet with each other, the positioning of the belt speed detecting portion can be simplified.

In the paper sheet storing and dispensing apparatus according to the first to third aspects of the invention described above, the tape dispensing position may be calculated using the number of pulses of the motor speed variation control unit.

According to the above configuration, since the tape dispensing position is detected by the calculation of the number of pulses using the motor speed variation control unit, it is possible to accurately detect the dispensing end of the tape and also the point adjacent to the end in the winding operation, and to detect the dispensing end of the tape and also the point adjacent to the end in the unwinding operation.

Detailed Description

A paper sheet storage and dispensing apparatus according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

The paper sheet storage and dispensing apparatus 1 of the present embodiment can be used as a temporary holding section or a storage section of different denominations of an automatic teller machine which processes banknotes S as one type of paper sheet. The conventional paper sheet storage and dispensing apparatus 1, which collects, holds, and dispenses bills one at a time from the top or the bottom in a conventional box-shaped space, replaces the conventional paper sheet storage and dispensing apparatus. The paper sheet storing and dispensing apparatus 1 of the present embodiment can process currency bills whose sizes are greatly different depending on the denomination, and transport and store the bills such that the longitudinal direction thereof is aligned with the transport direction.

As shown in FIG. 1, the paper sheet storing and dispensing apparatus 1 of the present embodiment is divided into a drive system space 22 and a collection space 23. Drive system space 22 is sandwiched between vertically aligned side discs 19 (shown in fig. 1) and support disc 20 parallel to side discs 19. The collecting space 23 is sandwiched between the support disc 20 and the side disc 21 parallel to and on the opposite side to the side disc 19. The side discs 19 and 20 are formed as flat discs. The side disc 21 has a stepped shape. One side of the side disc 21 forms a main disc portion 200 and the opposite side forms a stepped disc portion 201. Main disc portion 200 is parallel to side disc 19 and support disc 20. Stepped disk portion 201 is parallel to side disk 19 and backup disk 20 and is closer to backup disk 20 than main disk portion 200. Side disc 19, support disc 20 and side disc 21 are connected together by a plurality of pins or the like (not shown).

As shown in fig. 2 and 3, in the collection space 23, an inlet/outlet 2 connected to a conveyance path 50 (i.e., an external paper sheet conveyance section) on a side surface of a main body 202 of the automatic teller machine in which the paper sheet storage and dispensing apparatus 1 is disposed is provided. At the inlet/outlet 2, the banknotes S are received and dispensed to the main body 202 side. The inlet/outlet 2 has a pair of guide disc portions 205 and 206, and a top roller 3 and a bottom roller 4, and is substantially horizontally aligned. The pair of guide tray portions 205 and 206 are vertically positioned up and down so as to extend horizontally, and thus form a passage 204 therebetween for the passage of the banknotes S therealong. The top roller 3 and the bottom roller 4 are a pair of parallel feed rollers that can be in contact with each other and are disposed vertically facing each other so that they both protrude onto the passage 204 between the guide tray portions 205 and 206.

A tape T, one side of which is drawn out and fixed to the banknote collection drum 10 (i.e. the second reel drum), is looped around the bottom roller 4 of the inlet/outlet 2 so as to be able to pass between the bottom roller 4 and the top roller 3. The banknote collection drum 10 is arranged toward the rear as viewed from the inlet/outlet 2 and is parallel to the bottom roller 4. The tape T substantially reverses its extending direction after being looped around the bottom roller 4, and its transport path is formed by a plurality of, more specifically, three rollers 208, 209 and 210. The other side of the tape T is fixed to a tape winding drum 12 (i.e., a first reel drum) which is parallel to the banknote collection drum 10. The entrance/exit area Ta of the tape T connecting the banknote collection drum 10 and the bottom roller 4 together substantially coincides with the direction in which the passage 204 of the entrance/exit 2 extends. The bottom roller 4 is rotated by contact tension from the tape T, that is, rotated together with the transportation of the tape T. The top roller 3 also rotates along with the transport of the tape T or the banknotes S overlapped on the tape T and moving integrally with the tape T. The rollers 208, 209 and 210 for guiding the tape T are also rotated by the contact tension of the tape T.

The banknotes S conveyed from the conveyance path 50 while being divided into individual banknotes are fed at a uniform speed from the conveyance path 50 to the passage 204 between the pair of guide tray portions 205 and 206 of the inlet/outlet portion 2 by the conveyance driving force at the conveyance path 50 side. Subsequently, the middle position in the short-side direction of each banknote S is stacked on the tape T of the path 204 by the top roller 3 and the bottom roller 4. Next, the banknotes S are transported together with the tape T and wound around the banknote collection drum 10 together with the tape T to be collected and stored thereon. Specifically, the banknotes S are stacked on the top roller 3 side of the tape T by the top roller 3 and the bottom roller 4. The banknotes S move on the linear entrance/exit area Ta together with the portion of the tape T on which the banknotes S are superposed. The winding outer circumferential region Tb is formed by the outermost circumferential portions of those portions of the tape T which is wound on the banknote collection drum 10 and is adjacent to the upstream side of the inlet/outlet region Ta in the rotational direction of the banknote collection drum 10. Next, the banknotes S are wound on the tape T which has been wound on the banknote collection drum 10 from the boundary position between the entrance/exit region Ta and the winding outer circumferential region Tb, and sandwiched between the tape T and the banknote collection drum 10. In this way, since the banknotes S are wound around the banknote collection drum 10 in order together with the tapes T, they are collected on the banknote collection drum 10.

In contrast, when the portion of the tape T that has been overlapped on the banknotes S is transported away from the banknote collection drum 10 and reaches the linear entrance/exit section Ta, the banknotes S that have been collected on the banknote collection drum 10 are moved away from the winding outer circumferential section Tb together with the tape T and are dispensed. Subsequently, the banknotes S are separated from the tapes T at the entrance/exit 2 and are dispensed to the transport path 50 at the same uniform speed as described above, from which the transport direction of the transport path 50 has been reversed as described above.

The tape winding drum 12 and the banknote collection drum 10 are rotated in a predetermined banknote storage direction (i.e., clockwise in fig. 2 and 3). By rotating in this direction, as the tape T is dispensed from the tape winding drum 12, the tape T is wound onto the banknote collection drum 10, and the banknotes S are fed from the conveyance path 50 to the inlet/outlet 2 and stored on the banknote collection drum 10. This is a winding operation.

The tape winding drum 12 and the banknote collection drum 10 are also rotated in a predetermined banknote dispensing direction (i.e., counterclockwise in fig. 2 and 3) opposite to the above-described direction. By rotating in this direction, the tape T is dispensed from the banknote collection drum 10 while only the tape T is wound on the tape winding drum 12, so that the banknotes S stored on the banknote collection drum 10 are fed from the inlet/outlet 2 to the conveyance path 50. This is the unwinding operation.

In this way, the banknotes S can be stored or dispensed by performing the winding operation and the unwinding operation of the tape T between the tape winding drum 12 and the banknote collection drum 10. Both ends (i.e., a starting end and a finishing end) of the tape T are coupled to the outer circumferential surface of a corresponding one of the banknote collection drum 10 and the tape winding drum 12 by coupling members (not shown) and then wound thereon.

The banknote collection drum 10 has an axial length slightly longer than the short side length of the largest one of the banknotes S that are transported in its longitudinal direction aligned with the transport direction. The banknote collection drum 10 is supported on a shaft 11 aligned parallel to the top and bottom rollers 3, 4, that is, horizontally aligned, and is capable of rotating about the shaft 11.

As shown in fig. 1, the groove 14 is formed in a spiral shape extending in the circumferential direction on the outer circumferential surface of the banknote collection drum 10. The groove 14 forms a path for sensor light for detecting the presence of a banknote. Recessed portions 15 whose grooves are centered around the shaft 11 are formed at both ends in the axial direction of the banknote collection drum 10.

The tape winding drum 12 is rotatably supported on a shaft 13, and the shaft 13 is parallel to the rollers 3 and 4 at a position diagonally opposite to the inlet/outlet 2 in the collection space 23.

The tape winding drum 12 dispenses the tape T when the banknotes S are collected, and conversely, when the banknotes S are dispensed, collects the surplus tape T. Since the tape winding drum 12 winds only the tape T having a smaller width than the banknotes S in the overlapped state, the tape T has a shorter axial length than the banknote collection drum 10 and is set substantially the same width as the tape T here.

In the present embodiment, the banknote separating section 79 is disposed adjacent to the banknote collection drum 10. In a state where the banknotes S are dispensed from the banknote collection drum 10, when a portion of the tape T supporting the banknotes S on the outside reaches the entrance/exit section Ta, the banknote separating section 79 separates the banknotes S supported by the portion from the winding outer circumferential section Tb, which is a portion of the tape T not yet wound on the banknote collection drum 10, and guides the banknotes S together with the tape T to the entrance/exit section Ta. That is, in principle, when the banknotes S that have been collected on the banknote collection drum 10 are dispensed from the banknote collection drum 10, the banknote separation section 79 is put into use, and the dispensed banknotes S can be reliably separated from the banknote collection drum 10.

The banknote separation section 79 includes a banknote separation facilitating mechanism 80 and a banknote separation mechanism (i.e., separation section) 51. The banknote separation promoting mechanism 80 is located on the upstream side in the direction in which the banknotes S are dispensed, and is arranged at a position in contact with the banknote S closest to the dispensing side among the banknotes S wound around the banknote collection drum 10. The banknote separation facilitating mechanism 80 facilitates separation of the banknotes S from the winding outer circumferential zone Tb. The banknote separating mechanism 51 is disposed in close proximity to the downstream side in the dispensing direction of the banknotes S and is disposed on the dispensing side of the tape T, that is, on the bottom roller 4 side of the banknote collection drum 10. The banknote separating mechanism 51 separates the banknotes S from the winding outer circumferential zone Tb wound around the banknote collection drum 10 and causes them to be transported to the inlet/outlet zone Ta together with the tape T.

As shown in fig. 1 to 5, the banknote separation promoting mechanism 80 has a pair of shafts 82 parallel to the banknote collection drum 10. These shafts 82 are located in the support disc 20 and the side disc 21 so as to be coaxial with each other. These shafts 82 are disposed above the entrance/exit area Ta of the tape T when viewed from the axial direction of the drum.

The banknote separation promoting mechanism 80 has a pair of arm members 81 and a shaft 83, which are positioned on opposite sides of the collection space 23 of each of a pair of shafts 82. The pair of arm members 81 can rock about the shaft 82. The shaft 83 connects together end portions of a pair of arm members 81 on opposite sides of the shaft 82, and is parallel to the shaft 82. The pair of arm members 81 are parallel to each other, and the leading ends of the arm members 81 extend downward to a position outside the inlet/outlet area Ta of the tape T when viewed from the axial direction of the drum.

The banknote separation promoting mechanism 80 has a base member 84 supported by a shaft 83 so as to be swingable about the shaft 83 in a state of extending between the respective arm members 81. That is, the base member 84 is supported so as to be swingable around the arm member 81 which is also swingable.

The base member 84 is provided with a pair of shafts 88 and 89. These shafts 88 and 89 are provided on the outer side, that is, on the bottom side of the boundary position between the inlet/outlet region Ta and the winding outer circumferential region Tb on the circumferentially outermost side of the tape T wound around the banknote collection drum 10 so as to sandwich the tape T from both sides in the axial direction of the banknote collection drum 10. The separation promoting roller 85 and the separation promoting roller 86 are rotatably provided on a shaft 88 and a shaft 89, respectively. That is, the pair of separation facilitating rollers 85 and 86 are held on the base member 84 by the shafts 88 and 89. The pair of shafts 88 and 89 are inclined when viewed from the drum radial direction so that the opposite sides thereof are positioned on the downstream side in the dispensing direction when the banknotes S are dispensed from the banknote collection drum 10. As a result, the pair of separation facilitating rollers 85 and 86 are uniformly inclined so that the gap therebetween becomes narrower as it approaches the downstream side in the direction in which the banknotes S are dispensed from the banknote collecting drum 10, that is, as it approaches the inlet/outlet 2 thereof. In other words, the pair of separation promoting rollers 85 and 86 are disposed in a V shape that is tapered on the inlet/outlet 2 side. The specific angle of inclination of the shafts 88 and 89 is set to be substantially 10 ° with respect to the intersection angle α of the orthogonal lines extending from the central axis of each shaft. The minimum distance between the pair of separation facilitating rollers 85, 86 is wider than the width of the tape T, and the pair of separation facilitating rollers 85, 86 are disposed at positions on both outer sides of the tape T and away from the tape T, that is, so as not to contact the tape T.

The shaft 83 connects the pair of arm members 81 together and supports the base member 84. The auxiliary roller 87 is provided on the shaft 83 so as to be freely rotatable around the shaft 83. The position of the auxiliary roller 87 in the axial direction coincides with the center of the tape T, and the auxiliary roller 87 projects onto the banknote collection drum 10 side outside the base member 84 when viewed from the drum axial direction. The auxiliary roller 87 supported on the shaft 83 is smaller than the width of the tape T so as to be positioned on the inner side of both edge portions of the tape T. Since the auxiliary roller 87 is disposed against the winding outer circumferential area Tb of the tape T, the auxiliary roller 87 can maintain the distance between the winding outer circumferential area Tb and the base member 84. That is, when only a large amount of the tape T is wound on the banknote collecting drum 10 and the separation facilitating rollers 85 and 86 are not moved in the radial direction of the banknote collecting drum 10, the auxiliary roller 87 comes into contact with the tape T and causes the base member 84 to move so as to follow the outer radius of the tape T. As a result, the auxiliary roller 87 prevents the base member 84 and the tape T from directly contacting each other.

Joint pins 213 are attached to the base member 84 side of each of the pair of arm members 81. The engagement pins 214 are respectively mounted in the support tray 20 and the side tray 21 on opposite sides of the engagement pin 213 so that the engagement pins 214 sandwich the banknote collection drum 10. A tension spring (i.e., arm urging member) 91 is located between the engagement pins 213 and 214 on each side. The tension spring 91 urges the pair of arm members 81 in a direction in which the separation facilitating rollers 85 and 86 approach the banknote collection drum 10 (i.e., clockwise in fig. 2 and 3).

The engaging pins 215 are respectively installed at the center positions of the pair of arm members 81. An engagement pin 216 is mounted on the base member 84 on the arm member 81 side and the side opposite to the shaft 83. A tension spring (i.e., arm urging member) 90 is located between the engagement pins 215 and 216 on each side. These tension springs 90 urge the base member 84 in a direction opposite to the pair of arm members 81 so that the pair of separation facilitating rollers 85 and 86 approach the banknote collection drum 10 (i.e., counterclockwise in fig. 2 and 3).

A pair of separation facilitating rollers 85 and 86 are disposed to contact both sides in the transverse direction of the banknotes S held on the tape T at the central position in the transverse direction thereof by the urging force of the tension springs 90 and 91, and the banknotes S are the closest to the dispensing side among the banknotes S wound around the banknote collection drum 10. When the position of the banknote S closest to the dispensing side is changed in the radial direction of the banknote collection drum 10 in accordance with the change in the number of banknotes wound around the banknote collection drum 10, mainly, the arm member 81 also swings so as to follow such a change in position. That is, the banknote separation promoting mechanism 80 can move in the radial direction of the banknote collection drum 10 so as to track the number of banknotes wound around the banknote collection drum 10. In addition, the banknote separation promoting mechanism 80 contacts the banknotes S in the dispensing direction at the boundary position between the entrance/exit area Ta and the winding outer circumferential area Tb of the tape T regardless of the number of banknotes.

The banknotes S that are held on the tapes T at the central position in the lateral direction thereof and are closest to the dispensing side among the banknotes S wound around the banknote collection drum 10 move along with the dispensing of the tapes T. During this movement, in the banknote separation promoting mechanism 80, a pair of separation promoting rollers 85 and 86, which push both sides of the banknote S toward the tape T, are arranged on both sides of the tape T and are inclined such that a gap therebetween is narrowed as the gap approaches the downstream side in the dispensing direction of the banknote S. As a result, wrinkles extending in the dispensing direction are formed in the banknotes S on the side of the tape T, and the tape T side thereof is lifted away from the winding outer circumferential area Tb of the tape T, thus facilitating separation.

As shown in fig. 1 to 3 and 6, the banknote separating mechanism 51 has a guide tray 52. The guide plate 52 is directly mounted on the collection space 23 side of the side plate 21 by means of, for example, screws or the like (not shown) so as to extend between the shaft 11 and the inlet/outlet 2. The guide disc 52 is formed by a disc member having an L-shaped cross section, which is folded back from the side disc 21 onto the side of the collecting space 23. A pair of guide grooves 53 and 54 parallel to each other and inclined downward when approaching the inlet/outlet 2 side are formed at the center position of the guide plate 52. The upper guide groove 53 is closer to the shaft 11 than the lower guide groove 54. These guide grooves 53 and 54 are provided on the banknote collection drum 10 side, that is, on the upper side of the inlet/outlet region Ta of the tape T.

The banknote separating mechanism 51 has a base member 55. The base member 55 has a slide pin 62 slidably engaged in the guide groove 53 of the guide plate 52, and a slide pin 63 slidably engaged in the guide groove 54 of the guide plate 52. The seat member 55 slides between the support tray 20 and the slide tray 21 in the direction in which the guide grooves 53 and 54 extend. A slide groove 65 is also formed on the base member 55 so as to extend in parallel to the guide grooves 53 and 54 in the guide tray 52. A guide pin 64 mounted on the support plate 20 is engaged in the slide groove 65 so as to be relatively slidable. The base member 55 can perform a stable sliding motion using the guide grooves 53 and 54, the sliding groove 65, the sliding pins 62 and 63, and the sliding pin 64.

In general, the base member 55 is mounted on the banknote collection drum 10 side, that is, on the top side of the entrance/exit area Ta of the tape T. The base member 55 has a base portion 218, a base portion 219, and a connecting portion 220. The base portion 218 is disposed adjacent to the collection space 23 side of the side tray 21, and has slide pins 62 and 63 engaged in the guide grooves 53 and 54 of the guide tray 52. Base portion 219 is disposed adjacent to the collection space 23 side of backup tray 20 and has a guide groove 65 that slides when guided by a guide pin 64 provided on backup tray 20. The connecting portion 220 connects the base portions 218 and 219 together. The connecting portion 220 is provided to project onto the inlet/outlet region Ta of the tape T at the end portions of the base portions 218 and 219 on the opposite side of the banknote collection drum 10 as viewed from the drum axis direction.

The banknote separating mechanism 51 has a shaft 69, and the portion of the shaft 69 of the connecting portion 220 of the base member 55 inside the base portions 218 and 219 is parallel to the banknote collection drum 10 when viewed from the drum axis direction. The bill separating mechanism 51 has a guide roller 70 supported on a shaft 69 so as to be freely rotatable about the shaft 69. The guide roller 70 protrudes outside the connecting portion 220 on the side of the banknote collection drum 10. The position of the guide roller 70 in the drum axis direction matches the winding outer circumferential section Tb on the outermost circumference of the tape T wound on the banknote collection drum 10. The slide pins 62 and 63, the guide pin 64, the base member 55, the shaft 69, and the guide roller 70 described above constitute a slide portion 222 that slides relative to the banknote collection drum 10.

The banknote separating mechanism 51 has an engaging pin 60, an engaging pin 59, and a tension spring (i.e., urging member) 57. Dowel pin 60 is mounted on base portion 219 on the support tray 20 side of base member 55. The engaging pin 59 is mounted on the support plate 20 at a position on the extension line extending from the engaging pin 60 in the direction in which the slide groove 65 extends, outside the banknote collection drum 10. The tension spring 57 is located between the engagement pins 59 and 60. The bill separating mechanism 51 has the above-described slide pin 62, engaging pin 61, and tension spring (i.e., urging member) 58. The slide pin 62 is mounted on the base member 218 on the side disc 21 side of the base member 55. The engaging pin 61 is mounted on the support plate 21 at a position outside the banknote collection drum 10 on an extension line extending from the engaging pin 62 in the direction in which the guide grooves 53 and 54 extend. The tension spring 58 is located between the engagement pin 61 and the slide pin 62.

Accordingly, the base member 55, that is, the slide portion 222 is urged by the tension springs 57 and 58 in the direction of the center of the banknote collection drum 10. As a result, the sliding portion 222 causes the guide roller 70 held on the base member 55 to be disposed in contact with the outer circumferential surface of the banknote collection drum 10 when the tape T is not wound around the banknote collection drum 10, and to be disposed in contact with the winding outer circumferential section Tb of the tape T when the tape T is wound around the banknote collection drum 10. Accordingly, the sliding portion 222 slides so as to follow the size of the outer circumference, which varies depending on the number of tapes T and bills S wound on the bill collecting drum 10. That is, the guide roller 70 positions the base member 55 relative to the outer circumferential surface of the banknote collection drum 10 and the winding outer circumferential section Tb of the tape T. As a result, the base member 55 slides along the guide grooves 53 and 54 depending on the number of tapes T and banknotes S wound on the banknote collection drum 10. The guide roller 70 is rotated due to contact with the banknote collection drum 10 or the tape T.

Specifically, when the tape T and the banknotes S are not wound on the banknote collection drum 10, the base member 55 is positioned along the guide grooves 53 and 54 of the guide tray 52 on the side of the shaft 11 closest to the center of the banknote collection drum 10. When the tape T and the banknotes S are sufficiently wound around the banknote collection drum 10, the base member 55 is positioned along the guide grooves 53 and 54 of the side tray 52 away from the side of the shaft 11 which is substantially the center of the banknote collection drum 10. The sensor shielding portion 97 is provided on the base member 55. The sensor shielding section 97 is detected by the optical collecting section full capacity detecting sensor 96 which detects that the banknotes S collected on the banknote collecting drum 10 have reached the full capacity during the collecting operation. That is, when the bills are collected on the bill collecting drum 10, the outer circumference of the bill collecting drum 10 including the tapes T and the bills S becomes gradually larger because the tapes T and the bills S are wound. Along with this, the slide portion 222 of the banknote separating mechanism 51 including the sensor shielding portion 97 slides toward the inlet/outlet 2 side located on the outer side in the radial direction of the banknote collection drum 10. When the collecting section full capacity detecting sensor 96 detects the sensor shielding section 97, it detects that the banknotes S have been collected to the full capacity during the operation of collecting the banknotes S on the banknote collecting drum 10.

The banknote separating mechanism 51 has an axis 66 parallel to the banknote collection drum 10. The shaft 66 is provided in a part of the connecting portion 220 of the base portion 55 that protrudes from the base portions 218 and 219 when viewed from the drum axis direction. The banknote separating mechanism 51 has a separator (i.e., a separating member) 56 supported on a shaft 66 so as to be able to rock about the shaft 66. That is, the separator 56 is held in the slide portion 222 so as to be able to rock. The separator 56 is located in a space having a substantially acute shape formed by an inlet/outlet area Ta and an outer circumferential area Tb of the tape T wound around the banknote collection drum 10. The separator 56 has a separating distal portion 224 and a guide portion 225. A separating distal end portion 224 is formed at the end on the banknote collection drum 10 side. The leading portion 225 extends from the detached distal portion 224 along the entrance/exit Ta of the tape T. The distal separating portion 224 has an acute angle shape when viewed from the drum axis direction, and one of its surfaces is connected to the guide portion 225.

The banknote separator mechanism 51 also has an engagement pin 227 mounted on the separator 56, an engagement pin 228 mounted on the base member 55, and a tension spring (i.e., urging member) 67 located between the engagement pins 227 and 228. When no tape T is wound on the banknote separator drum 10, the banknote separator mechanism 51 urges the separating distal end member 224 toward the outer circumferential portion of the banknote separator drum 10 using the tension spring 67, and when the tape T has been wound on the banknote separator drum 10, the banknote separator mechanism 51 urges the separating distal end portion in a direction (i.e., clockwise in fig. 6) in which the separating distal end portion meets the winding outer circumferential region Tb of the tape T using the tension spring 67. As a result, when the tape T is wound on the banknote collection drum 10, the separator 56 causes the separating distal end portion 224 to be always disposed in contact with the winding outer circumferential region.

That is, when the tape T and the banknotes S are wound on the banknote collection drum 10, a slight difference in diameter is generated between a portion with the banknotes S and a portion without the banknotes S. For this reason, there is a slight movement in the position of the separator 56 held by the sliding portion 222, and the sliding portion 222 is arranged with respect to the winding outer circumferential section Tb of the tape T by the guide roller 70 arranged against the tape T. For this reason, by enabling the separator 56 to rock, any difference in diameter is absorbed. The guide roller 70 and the separator 56 have a width such that they are contained within the tape T in the drum axis direction.

When the part of the tape T that is holding the banknotes S reaches the entrance/exit area Ta when the banknotes S are dispensed from the banknote collection drum 10, there is generated a case where the distal end portion of the banknotes S being held by the part tries to move while it is still attached to the winding outer circumferential area Tb of the tape T. In this case, for example, the separating distal end 224 of the separator 56 disposed against the winding outer circumferential region Tb separates the banknotes S by shaving the distal end portions of the banknotes S from the winding outer circumferential portion Tb of the tape T. In addition, the banknotes S separated by the separating distal end portion 224 in this way are guided to the entrance/exit 2, that is, toward the downstream side, by the guide portion 225 facing the entrance/exit area Ta of the tape T. As described above, the separator 56 that actually separates and guides the bills S is swingably supported on the base member 55, and the base member 55 slides along the guide grooves 53 and 54 depending on the number of tapes T and bills S wound on the bill collecting drum 10.

The guide portion 225 has a middle guide surface 230, an entrance-side guide portion 231, and a dispensing-side guide surface 232. The inlet-side guide surface 231 is positioned on the inlet/outlet 2 side of the intermediate guide surface 230. In a state where the intermediate guide surface 230 is parallel to the entrance/exit area Ta of the tape T, the entrance-side guide surface 231 is inclined so as to move away from the entrance/exit area Ta when it approaches the entrance/exit 2. The dispensing-side guide surface 232 is positioned on the banknote collection drum 10 side of the intermediate guide surface 230. In a state where the intermediate guide surface 230 is parallel to the entrance/exit region Ta of the tape T, the dispensing-side guide surface 232 is inclined so as to move away from the entrance/exit region Ta when it approaches the banknote collection drum 10 side. The intermediate guide surface 230 has a larger inclination angle with respect to the inlet-side guide surface 231 than the dispensing-side guide surface 232. The dispensing-side guide surface 232 guides the banknotes S, which have been smoothly separated from the banknote collection drum 10 by the separating distal end portion 224 between the separator 56 and the entrance/exit area Ta of the tape T, to the entrance/exit 2 side. The inlet-side guide surface 231 can guide even the banknotes S having twist, crease, or bend therein, which are smoothly transported from the inlet/outlet 2 side to the banknote collection drum 10 between the separator 56 and the inlet/outlet area Ta of the tape T.

The banknote separating mechanism 51 also has a transport roller 71 which is supported on a shaft 66 so as to be rotatable about the shaft 66, wherein the shaft forms a rocking center of the separator 56 with respect to the base member 55.

The conveying roller 71 is always in contact with the guide roller 70. Further, a part of the conveying roller 71 protrudes from the intermediate guide surface 230 to the entrance/exit area Ta on the side of the tape T, and can be in contact with the tape T located at the entrance/exit area Ta or the banknotes S mounted on the tape T located at the entrance/exit area Ta. As a result, when the banknote collection drum 10 rotates, the transport roller 71 is in contact with the guide roller 70, the guide roller 70 rotates in the opposite direction by being in contact with the banknote collection drum 10, and the transport roller 71 rotates in the opposite direction to the guide roller 70. As a result, the conveyance roller 71 rotates in the same direction as the banknote collection drum 10. Accordingly, when dispensing the banknotes, the conveyance roller 71 grasps the banknotes S separated from the winding outer circumferential region Tb of the tape T on the banknote collection drum 10 between it and the entrance/exit region Ta of the tape T and conveys it to the entrance/exit 2 side, that is, to the downstream side.

As shown in fig. 8, when the tape T has been dispensed from the banknote collection drum 10 to the maximum, the inlet/outlet area Ta of the tape T overlaps with a line extending from the inlet/outlet 2. When the tape T and the banknotes S are wound on the banknote collection drum 10, as shown in fig. 9 and 10, the dispensing start position P, which is a boundary between the inlet/outlet area Ta and the winding outer circumferential area Tb of the tape T, is gradually moved to the inlet/outlet 2 side in the extending line direction of the inlet/outlet 2 in accordance with the winding amount of the tape T and the banknotes S, and at the same time, is gradually moved away from the banknote collection drum 10 in the radial direction. As a result, the entrance/exit area Ta of the tape T is inclined so that the entrance/exit 2 side thereof is on the upper side. In contrast, the sliding portion 222 moving along the guide grooves 53 and 54 slides in a manner of being disposed lower with respect to a horizontal line extending from the inlet/outlet 2, the closer to the inlet/outlet 2 thereof. As a result, regardless of the number of the tapes T and the banknotes S wound on the banknote collection drum 10, the sliding section 222 slides in a direction in which it always intersects with the direction in which the tapes T are dispensed from the banknote collection drum 10, that is, the direction in which the inlet/outlet section Ta extends.

Subsequently, the drive system will be described mainly with reference to fig. 1 and 7A and 7B.

The shaft 11 is rotatably supported by the main disc portion 200 of the side disc 19, the support disc 20 and the side disc 21 so as to be perpendicular to these members. A torque limiter 17 mounted on a support disc 20 by a mounting disc 18 is inserted through the shaft 11. An engagement member 16 engaged with a torque limiter 17 is fixed to the shaft 11. That is, the torque limiter 17 is provided between the engagement member 16 fixed to the shaft 11 and the mounting disk 18 which is a non-rotating portion. The torque limiter 17 and the engagement member 16 are arranged in a recessed portion 15 of the banknote accumulating drum 10.

A torque limiter 110 inserted through the shaft 11 is mounted in the other recess 15 of the banknote accumulating drum 10. An engaging member 111 engaged with the torque limiter 110 is fixed on the shaft 11 while being disposed in the recessed portion 15.

The torque limiter 17 allows only the shaft 11 to rotate when the torque limiter 17 receives a rotation torque from the motor 39 when storing bills or when the torque limiter 17 receives a rotation torque caused by tension generated in the tape T by the tape winding drum 12 when dispensing bills. That is, when storing or dispensing banknotes, the torque limiter 17 does not allow the shaft 11 to rotate unless necessary. When the outer diameters of the banknote collection drum 10 and the tape winding drum 12 are significantly different and the difference between the rotational speeds thereof increases due to the winding of the tape T and the banknote S, the torque limiter 110 generates a slip between the shaft 11 and the banknote collection drum 10, thus absorbing the difference between the speeds thereof. As a result, any difference in the rotational speed caused by the change in the outer diameter can be absorbed (abs) without performing any special gear change or the like. The tension of the tape T can thus be constant, while any excessive shock is hard to act on the tape T even if a sudden shock such as a banknote jam or the like occurs.

The shaft 13 is rotatably supported by the stepped disk portion 201 of the side disk 19, the support disk 20, and the side disk 21 so as to be perpendicular to these components. A torque limiter 27 mounted on support disk 20 by mounting disk 28 is inserted through shaft 13. An engagement member 26 engaged with the torque limiter 27 is fixed to the shaft 13. That is, the torque limiter 27 is provided between the engagement member 26 fixed to the shaft 13 and the mounting plate 28, which is a non-rotating portion.

A torque limiter 120 inserted through the shaft 13 is mounted on the tape winding drum 12 supported on the shaft 13 by a mounting plate 122. An engagement member 121 engaged with the torque limiter 120 is fixed to the shaft 13.

The torque limiter 27 allows only the shaft 13 to rotate when the torque limiter 27 receives a rotation torque from the motor 39 when dispensing bills or when storing bills, the torque limiter 27 receives a rotation torque caused by a tension generated in the tape T by the bill collecting drum 10. That is, when storing or dispensing banknotes, the torque limiter 27 does not allow the shaft 13 to rotate unless necessary. When the outer diameters of the banknote collection drum 10 and the tape winding drum 12 are significantly different and the difference between the rotation speeds thereof increases because the tape T and the banknote S are wound, the torque limiter 120 generates slip between the shaft 13 and the tape winding drum 12, thereby absorbing the difference between the speeds thereof. As a result, any difference in the rotational speed caused by the change in the outer diameter can be eliminated without performing any gear change or the like. The tension of the tape T can thus be constant, and at the same time, even if sudden shocks such as a banknote jam occur, any excessive shocks will hardly act on the tape T.

The shaft 109 is rotatably supported by the stepped disk portion 201 of the side disk 19, the backup disk 20, and the side disk 21 so as to be perpendicular to these components. Shafts 49 and 108 are supported on support plate 20 to be perpendicular to support plate 20. Shaft 49 is able to rotate relative to support disk 20, while shaft 108 is fixed to support disk 20.

The gear 103 is fixed to a portion of the shaft 49 on the collecting space 23 side. This gear 103 meshes with the gear 34 of the motor 39, also arranged on the same side of the collecting space 23. The electromagnetic clutch 100 is mounted on a portion of the shaft 49 on the drive system space 22 side. The gear 104 is provided on the shaft 49 via the electromagnetic clutch 100. That is, the driving force from the motor 39 is transmitted to the electromagnetic clutch 100 through the gears 34 and 103 and the shaft 49. When the electromagnetic clutch 100 is engaged (that is, when the electromagnetic clutch 100 enters an engaged state (on state)), the shaft 49 rotates together with the gear 104, and when the electromagnetic clutch 100 is disengaged (that is, when the electromagnetic clutch 100 enters a disengaged state (off state)), the shaft 49 freely idles in a state of being disengaged from the gear 104.

The gear 105 is disposed at a part of the drive system space 22 side of the fixed shaft 108 through the electromagnetic brake 102. The gear 105 meshes with the gear 104. When this electromagnetic brake 102 is disengaged (that is, when the electromagnetic brake 102 enters the disengaged state), the gear 105 is in the free-wheeling state, and when the electromagnetic brake 102 is engaged (that is, when the electromagnetic brake 102 enters the engaged state), the gear 105 is fixed on the fixed shaft 108, and braking can be applied thereto to immediately stop it.

A gear 106 meshing with the gear 105 is fixed to a part of the shaft 109 on the drive system space 22 side, and a gear 107 is also fixed to the shaft 109. A manually operated pulley 112 is fixed to a portion of the shaft 109 outside the step disc portion 201.

The saw-tooth pulley 30 is rotatably provided on a portion of the shaft 11 on the drive system space 22 side via a one-way clutch 31. The saw-tooth pulley 32 is also rotatably provided on the portion of the shaft 13 on the drive system space 22 side through a one-way clutch 33. The serrated timing belt 38 is endlessly moved by the serrated pulleys 30 and 32.

When the serrated pulley 30, the shaft 11, and the banknote collection drum 10 are rotated integrally, a driving force in the winding direction that rotates the tape T in the winding direction is applied to the serrated pulley 30 through the timing belt 38, and the one-way clutch 31 is in a locked state that rotates the shaft 11 integrally with the serrated pulley 30. In contrast, when the serrated pulley 30, the shaft 11, and the banknote collection drum 10 are integrally rotated, a driving force in the dispensing direction that causes the tape T to rotate in the dispensing direction is applied to the serrated pulley 30, and the one-way clutch 31 places the shaft 11 in a free state with respect to the serrated pulley 30.

When the saw tooth pulley 32, the shaft 13 and the belt winding drum 12 are integrally rotated, a driving force in a winding direction that rotates the belt T in the winding direction is applied to the saw tooth pulley 32 through the timing belt 38, and the one-way clutch 33 is in a locked state that rotates the shaft 13 integrally with the saw tooth pulley 32. In contrast, when the saw-tooth pulley 32, the shaft 13 and the tape winding drum 12 rotate integrally, a driving force in the dispensing direction that causes the tape T to rotate in the dispensing direction is applied to the saw-tooth pulley 32, and the one-way clutch 33 places the shaft 13 in a free state with respect to the saw-tooth pulley 32.

The timing belt 38 is also looped through a pulley 35 that applies tension to the timing belt 38. The support member 36 is mounted on the support plate 20 and supports the pulley 35 while allowing rotation thereof. Two elongated mounting holes 37 are provided in the support member 36. By adjusting the mounting position of the support member 36 with respect to the support plate 20 within the range of the mounting hole 37, the tension of the timing belt 38 can be adjusted.

As shown in fig. 2, the collection paper sheet sensors 40a and 40b are arranged such that their sensor optical paths pass through the sensor optical path groove 14 provided in the banknote collection drum 10. Other detection is performed by these collection paper sheet detection sensors 40a and 40b, and in these detection sensors 40a and 40b, it is detected whether the banknotes S remain collected (i.e., wound) on the banknote collection drum 10. The reason why the two collection paper sheet sensors 40a and 40b are provided is that the length of the outer circumference of the banknote collection drum 10 is larger than the length of the long side of the smallest banknote S, and if only one collection paper sheet sensor is provided, it is possible that the presence of the banknote S that has been wound around the banknote collection drum 10 cannot be completely detected when the banknote collection drum 10 is stopped. Accordingly, if the length of the outer circumference of the banknote collection drum 10 is smaller than the length of the long side of the smallest banknote S, the presence of the banknote S can be completely detected using one collection paper sheet sensor. If control is performed such that the banknote collection drum 10 is slightly rotated and the width range of the outer circumferential surface is arranged on the sensor optical path, the presence of the banknote S can be detected with one collection paper sheet sensor bend.

An optical pass-through confirmation sensor 41 (i.e., a trigger sensor) that detects the passage of the banknotes S through the light shield is disposed directly outside the top roller 3 and the bottom roller 4 of the inlet/outlet 2. This feed-in of the banknotes S from the transport path 50 to the inlet/outlet 2 and the feed-out of the banknotes S from the inlet/outlet 2 to the transport path 50 are detected by the confirmation sensor 41. The number of banknotes S stored and dispensed is also counted by the confirmation sensor 41, and the timing for controlling the respective electromagnetic clutches 100 and 102 is detected.

An optical first end detection sensor (i.e., dispensing end detection section) 95 is provided between the bottom roller 4 and the banknote collection drum 10. The first end detection sensor 95 detects that the tape T that has been dispensed from the banknote collection drum 10 reaches the end, that is, that dispensing of the tape T from the banknote collection drum 10 has ended by detecting a detection portion (not shown) formed on the tape T. When the tape T is composed of a translucent resin material as its main part, for example, the detection section may be formed on the tape T by forming all or part of the detection section as a non-transparent colored section or the like. It is also possible to provide a plurality of detection portions at positions such as the end of the tape T dispensed from the banknote collection drum 10, a point adjacent to the end, the end of the tape T dispensed from the tape winding drum 12, and a point adjacent to the end.

The tape end detecting section 44 is provided near the tape winding drum 12. The tape end detecting section 44 detects that the end of the tape T dispensed from the tape winding drum 12 has been reached. The end of tape detecting section 44 has a shaft 43, an end of tape detecting arm 45, a roller 46, a tension spring 48, and a second end detecting sensor 42. The shaft 43 is arranged parallel to the shaft 13 near the tape winding drum 12. The tape detecting arm 45 is provided so as to be swingable about the shaft 43. The roller 46 is disposed parallel to the shaft 43, at an end portion of the shaft 43 on the opposite side of the belt end detection arm 45. The tension spring 48 urges the tape end detection arm 45 in a direction in which the roller 46 contacts the outermost circumferential surface of the tape T wound on the tape winding drum 12 (i.e., counterclockwise as viewed in fig. 2 and 3). The second end detection sensor 42 is an optical sensor, and the second end detection sensor 42 detects a sensor shielding portion 47 formed on the tape end detection arm 45 when the tape T is dispensed from the tape winding drum 12 to a point adjacent to the end thereof.

Specifically, the tape T wound on the tape winding drum 12 is dispensed as the storage operation of the banknotes S proceeds, and the outermost circumferential diameter of the tape T wound on the tape winding drum 12 gradually becomes smaller. At this time, the tape end detection arm 45 abutting against the outermost circumference pressing roller 46 is gradually swung around the shaft 43 to follow the outermost circumference by the spring force of the tension spring 48. When the sensor shielding portion 47 of the tape end detecting arm 45 shields the optical path of the second end detecting sensor 42, the second end detecting sensor 42 detects that the tape T has been dispensed from the tape winding drum 12 to the vicinity of the end thereof.

Without using the tape end detecting section 44, it is also possible to detect that the tape T has been dispensed from the tape winding drum 12 to near the end thereof by using the above-described collecting section full capacity detecting sensor 96 and sensor shielding section 97 provided on the base member 55 of the banknote separating mechanism 51. That is, when the sensor shielding portion 97 of the base member 55 is moved out of a certain predetermined position, it can be determined that the tape T has been dispensed until the end thereof is approached. The collecting section full capacity detecting sensor 96 corresponds to a position on the outer circumferential portion of the banknote collecting drum 10 on which the tapes T and the banknotes S have been wound on the banknote collecting drum 10, and the banknote collecting drum 10 includes the tapes T and the banknotes S. For this reason, if the banknotes S are not collected and only the tapes T have been wound on the banknote collection drum 10, it is possible that all the tapes T are dispensed from the tape winding drum 12 before the sensor shielding section 97 is detected by the collection section full capacity detection sensor 96. In this case, when the banknotes S are not collected and only the tapes T are wound on the banknote collection drum 10, it is necessary to provide a sensor for detecting the sensor shielding portion 97 at a position where a point adjacent to the end of the tape T can be detected, and when the position is exceeded, it is necessary to detect that the tape T has been dispensed adjacent to the end. Also in this case, it is necessary to use this sensor in combination with the first end detection sensor 95.

Specifically, in the present embodiment, the opaque detection portions are respectively provided on the transparent tapes T so that the end portion of the tape T on the banknote collection drum 10 side and the end portion of the tape T on the tape winding drum 12 side can be detected by the first end detection sensor 95. When the detection portion for detecting the end portion on the tape winding drum 12 side is detected by the first end detection sensor 95 and the second end detection sensor 42 of the tape end detection portion 44 has detected the sensor shielding portion 47, it is recognized that the tape T has reached the end portion thereof with respect to the tape winding drum 12. In contrast, when the detection section for detecting the end portion on the banknote collecting drum 10 side is detected by the first end detection sensor 95 and the second end detection sensor 42 of the tape end detection section 44 does not detect the sensor shielding section 47, it is recognized that the tape T has reached the end portion with respect to the banknote collecting drum 10.

Normally, each time a banknote S storage instruction is issued, the banknote S is collected on the banknote collection drum 10. At this time, this full capacity detection for the banknote collection drum 10 is controlled by determining the number of banknotes collected by using the upper phase control unit (i.e., the motor speed variable control unit, the winding control unit, and the unwinding control unit) C shown in fig. 2. If an unexpected situation or the like occurs, which causes the full capacity of the banknote collection drum 10 to be detected by the collection portion full capacity detection sensor 96, or when the ends of the tape T are detected by the first end detection sensor 95 and the second end detection sensor 42 of the tape T, an emergency stop is effected on the banknote collection drum 10.

A rotational speed detection disc (i.e., a belt speed detection portion) 235 is fixed on the support shaft 234 of the bottom roller 4. The rotation amount of the rotational speed detection disc 235, that is, the rotation amount of the bottom roller 4 is detected by a rotation amount detection sensor (i.e., a belt speed detection portion) 9 adjacent to the rotational speed detection disc 235. The control unit C calculates the transport speed of the tape T at the entrance/exit 2, that is, the speed at which the tape T transports the banknotes S, based on the amount of rotation speed per unit time of the bottom roller 4 detected by the rotation amount detecting sensor 9 located on the bottom roller 4. When the winding operation is performed to store the banknotes S on the banknote collection drum 10, the control unit C controls the amount of rotation of the motor 39 so that the amount of rotation detected by the rotation amount detection sensor 9 (i.e., the transport speed of the tape T, i.e., the banknotes S) is maintained at a predetermined fixed value for the winding operation. Also, when the unwinding operation is performed to dispense the banknotes S from the banknote collection drum 10, the control unit C controls the amount of rotation of the motor 39 so that the amount of rotation detected by the rotation amount detection sensor 9 (i.e., the conveyance speed of the tape T, that is, the banknotes S) is maintained at a predetermined fixed value for the unwinding operation. The motor 39 may be a pulse motor capable of forward and reverse rotation. Due to the control of the number of pulses of the motor control IC built into the D/a converter executed by the control unit C, the rotational speed of the motor 39 is maintained at an arbitrary uniform speed corresponding to the number of pulses, and if the setting is changed, the motor 39 can be changed to an arbitrary speed corresponding to the number of pulses.

When the banknotes S are stored, if the electromagnetic clutch 100 of the shaft 49 is engaged (that is, the electromagnetic clutch 100 is brought into an engaged state) and the electromagnetic brake 102 of the shaft 108 is released (that is, the electromagnetic brake 102 is brought into a disengaged state), and the motor 39 is rotated in the banknote storage direction, the rotational force from the motor 39 applies rotation in the banknote storage direction (that is, clockwise direction in fig. 2 and 3) to the shaft 11 through the timing belt 38. As a result, the banknote collection drum 10 is rotated in the banknote storing direction (e.g., clockwise in fig. 2 and 3) by the torque limiter 17, and the tapes T and the banknotes S are wound. At this time, the tape winding drum 12 and the shaft 13 are also rotated by the tape T.

At this time, as the tape T and the banknotes S are wound on the banknote collection drum 10, the outer diameter of the banknote collection drum 10 gradually becomes wider. In contrast, as the tape T is dispensed from the banknote collection drum 10, the outer diameter of the tape winding drum 12 gradually narrows. In this way, since the difference between the outer diameters of the banknote collection drum 10 and the tape winding drum 12 becomes large to cause the difference between the rotational speeds thereof to become large, in some cases, there is a possibility that an accident such as gear skipping or the like occurs. However, these differences can be absorbed by the action of the torque limiter 120 provided between the shaft 13 and the tape winding drum 12.

When the winding by the banknote collection drum 10 is finished, that is, when it is detected by the confirmation sensor 41 that the number of banknotes required to be stored has been stored, the electromagnetic clutch 100 of the shaft 49 is disengaged, and the driving force of the motor 39 is interrupted. Along with this, the electromagnetic brake 102 of the shaft 108 is engaged, so that the brake is applied to the timing belt 38 and the shaft 11, and the banknote collection drum 10 is stopped by the torque limiter 17 provided between the banknote collection drum 10 and the supporting plate 20. As a result, the tape winding drum 12 freely idling by the tape T is stopped by the torque limiter 27 provided between the tape winding drum 12 and the backup plate 20. In this way, the electromagnetic clutch 100 switches between transmitting and interrupting the driving force arriving from the motor 39 via the drive system, and the electromagnetic brake 102 applies sufficient braking to the drive system to stop the banknote collection drum 10.

In contrast, when the banknotes S are dispensed, if the electromagnetic clutch 100 of the shaft 49 is engaged (i.e., the electromagnetic clutch 100 is brought into the engaged state), the electromagnetic brake 102 of the shaft 108 is released (i.e., the electromagnetic brake 102 is brought into the disengaged state), and the motor 39 is rotated in the banknote dispensing direction, the rotational force from the motor 39 is applied to the shaft 13 in the banknote dispensing direction (i.e., counterclockwise in fig. 2 and 3) by the timing belt 38. As a result, the tape winding drum 12 is rotated in the bill dispensing direction (i.e., counterclockwise in fig. 2 and 3) via the torque limiter 27, and the tape T is wound thereon. At this time, the banknote collection drum 10 and the shaft 11 are also allowed to freely idle by the tape T.

At this time, as the tape T is wound, the outer diameter of the tape winding drum 12 becomes gradually larger. In contrast, as the tapes T and the banknotes S are dispensed therefrom, the outer diameter of the banknote collection drum 10 gradually becomes smaller. In this way, since the difference between the outer diameters of the banknote collection drum 10 and the tape winding drum 12 becomes large so that the difference between the rotational speeds thereof becomes large, in some cases, there is a possibility that an accident such as gear skipping or the like occurs. However, these differences are absorbed by the action of the torque limiter 110 provided between the shaft 11 and the banknote collection drum 10.

When the winding of the drum 12 by this tape has ended, that is, when it is detected by the pass-through confirmation sensor 41 that the amount of the bills S required to be dispensed has been dispensed, the electromagnetic clutch 100 of the shaft 49 is disengaged, and the driving force of the motor 39 is interrupted. Along with this, the electromagnetic brake 102 of the shaft 108 is engaged, so that the brake is applied to the timing belt 38, and the shaft 13 and the tape winding drum 12 are stopped by the torque limiter 27 provided between the tape winding drum 12 and the backup plate 20. As a result, the banknote collection drum 10 freely idling by the tape T is stopped by the torque limiter 17 provided between the tape winding drum 10 and the supporting tray 20. At this time, the collected banknote detection sensors 40a and 40b report to the control unit C that no banknote remains on the banknote collection drum 10. In this way, the electromagnetic brake 102 applies sufficient braking to the drive system to stop the tape winding drum 12.

The paper sheet storing and dispensing apparatus 1 of the present embodiment having the above-described structure can be used as a temporary holding portion in, for example, an automatic teller machine. In this case, the paper sheet storing and dispensing apparatus 1 operates in the following manner.

The paper sheet storing and dispensing apparatus 1 serving as a temporary holding section in the automatic teller machine stores various denominations of money loaded in the automatic teller machine by an operator until it receives a storage confirmation instruction.

When a storage operation such as loading of the banknotes S is completed by an operator and an operation to start counting is initiated (such as by pressing a button), the control unit C causes the loaded banknotes S to be drawn into the body of the machine and issues operation instructions to the transport system including the transport path 50 to cause the banknotes to be sorted, counted and temporarily stored, and to cause any broken banknotes to be rejected. At the same time, the control unit C issues a drive instruction to the motor 39 of the paper sheet storing and dispensing apparatus 1, instructing it to rotate in the direction in which the banknotes are stored, and causing the motor 39 to rotate. At this time, since the electromagnetic clutch 100 and the electromagnetic brake 102 are disengaged, the drive is not transmitted to the shaft 11 and the shaft 13, and the drive from the motor 39 at the time of disengagement merely causes the gear 103 of the shaft 49 to idle.

Subsequently, since the passage confirmation sensor 41 of the inlet/outlet 2 is shielded, when it is detected that the temporarily stored bills have been sucked into the inlet/outlet 2 from the conveyance path 50, the control unit C engages the electromagnetic clutch 100, and thus the drive from the motor 39 is transmitted to the shaft 11. As a result, the winding operation by the banknote collection drum 10 is started, and the driving force from the motor 39 is transmitted to the shaft 11 through the timing belt 38, thereby rotating the banknote collection drum 10 in the banknote collection direction (i.e., clockwise direction in fig. 2 and 3). In this way, the tapes T are sequentially dispensed from the tape winding drum 12 and wound onto the banknote collection drum 10. At this time, the banknotes S, which have been supplied from the inlet/outlet 2 one by one, separately from each other, and to be temporarily held, are overlapped on the inlet/outlet area Ta of the tape T by the bottom roller 3 and the top roller 4, and then wound on the banknote collection drum 10 together with the tape T. In addition, at this time, the banknotes S having entered through the inlet/outlet 2 are guided by the suction-side guide surface 231 of the guide portion 225 of the separator 56, and are smoothly sucked between the separator 56 and the inlet/outlet region Ta of the tape T. The banknotes S are then received with a conveying force from the conveying roller 71 in the direction of the banknote collection drum 10, and the conveying roller 71 is caused to rotate by the guide roller 70 as the banknote collection drum 10 rotates, which causes the banknotes S to be wound around the banknote collection drum 10. During this winding operation, the control unit C controls the rotational speed of the motor 39 so that the transport speed of the tape T at the entrance/exit 2 detected by the rotational amount detection sensor 9 is maintained at a fixed speed that is faster than the fixed transport speed of the banknotes S on the transport path 50 by a predetermined amount (e.g., 5%).

The control unit C disengages the electromagnetic clutch 100 at a point of time when a predetermined time required for storing the bills S has elapsed after a point of time when the rear end portion of the bills S, the distal end side of which has been wound around the bill collecting drum 10, passes the through-path confirmation sensor 41 or after a point of time when the distal end of the bills S sucked through the inlet/outlet 2 has been detected by the confirmation sensor 41. Thereupon, the control unit C engages the electromagnetic brake 102, so that the drive from the electric motor 39 is no longer transmitted to the shaft 11 and the braking force is applied to the timing belt 38. As a result, the rotation of the shaft 11 is promptly stopped by the action of the torque limiter 17. The control unit C repeats the above winding operation each time the banknotes S to be temporarily held are detected by the passage confirmation sensor 41 of the inlet/outlet 2.

When all the stored banknotes S have been stored in the paper piece storage and dispensing apparatus 1 or have been returned to the operator as broken banknotes, the control unit C shows the total number of banknotes temporarily held on the display unit (not shown). While the total number is displayed, the operator is caused to perform the next processing operation, that is, to confirm or cancel the storage of the temporarily held bills. If the operator confirms the storage, an operation of confirming the storage is performed, and if the operator cancels the storage, an operation of canceling the storage is performed. Accordingly, the control unit C issues instructions to the respective locations to start the respective processes. That is, in the transport system of each section of the automatic teller machine, driving including transport on the transport belt 50 in the opposite direction is performed, and an instruction to drive in the bill dispensing direction is issued to the motor 39, thereby causing the motor 39 to rotate. The electromagnetic clutch 100 is then engaged, and the driving force of the motor 39 is transmitted to the shaft 13, so that the unwinding operation is started.

As a result, the driving force of the motor 39 is transmitted to the shaft 13 through the timing belt 38, and the belt winding drum 12 rotates in the banknote dispensing direction (i.e., counterclockwise in fig. 2 and 3). As a result, the tapes T and the banknotes S are dispensed from the banknote collection drum 10 in order, and only the tapes T are individually wound on the tape winding drum 12. At this time, due to the action of the banknote separation promoting mechanism 80, wrinkles extending in the banknote conveyance direction may be formed on the tape T side of the banknotes S being dispensed from the banknote collection drum 10. In this way, the separating distal end portion 224 of the separator 56 of the banknote separating mechanism 51 enters the wrinkled portion of the banknotes S whose separation from the banknote collection drum 10 has been promoted. As a result, the banknotes S are reliably separated from the winding outer circumferential region Tb of the tape T wound on the banknote collection drum 10 and conveyed to the inlet/outlet 2 while being guided by the dispensing-side guide surface 232 of the guide portion 225 of the separator 56 between the banknotes S and the inlet/outlet region Ta of the tape T. At this time, a conveying force toward the inlet/outlet 2 side is applied from the conveying roller 71 to the banknotes S, and the conveying roller 71 is rotated by the guide roller 70 with the rotation of the banknote collection drum 10.

In this way, the bills S stored on the bill collecting drum 10 are dispensed from the inlet/outlet 2 and conveyed to the conveyance path 50, and only the tape T is wound on the tape winding drum 12. During this unwinding operation, the control unit C controls the rotation speed of the motor 39 so that the transport speed of the tape T at the entrance/exit 2 detected by the rotation amount detection sensor 9 is maintained at a fixed speed that is faster than the fixed transport speed of the banknotes on the transport path 50 by a predetermined amount (e.g., 5%).

In the case of a storage confirmation operation, the banknotes S pass through a sorting section (not shown) for confirming the denomination again, and are then transferred to a different storage section depending on the denomination thereof. In the case of the cancel operation, the banknotes S are transported to the money output port of the automatic teller machine.

During the unwinding operation, when the end of the tape T on the banknote collection drum 10 side is detected, that is, when the end of dispensing of the tape T is detected by the first end detection sensor 95 and the second end detection sensor 42, the control unit C disengages the electromagnetic clutch 100 and engages the electromagnetic brake 102, so that the driving force of the motor 39 is not transmitted to the shaft 13, that is, to the tape winding drum 12. As a result, the rotation of the shaft 13, that is, the rotation of the tape winding drum 12, is rapidly stopped due to the action of the torque limiter 27.

Even if a sudden temporary change in voltage, a jam of the banknotes S, a jam of the tape T or a breakage of the tape T occurs during the winding operation or the unwinding operation as described above, it is possible to immediately detect an abnormality in the speed of the tape T by the rotation amount detecting sensor 9. Accordingly, when an abnormality is detected, the winding operation or the unwinding operation performed at that time can be promptly stopped.

According to the above-described paper sheet storing and dispensing apparatus 1 of the present embodiment, the conveying speed of the tape T at the entrance/exit 2 is detected by the rotation amount detection plate 235 and the rotation amount detection sensor 9. For this reason, compared to when the tape transport speed is manually calculated from the diameter of the outer circumference or the like wound on the drum, which varies depending on the number of drum windings around the tape or the number of bills stored on the drum, etc., the transport speed of the tape T can be easily and accurately measured.

In addition, during the winding operation initiated when the banknote S is detected to be fed to the inlet/outlet 2 by the confirmation sensor 41, the control unit C controls the motor 39 so that the transport speed of the tape T detected by the rotation amount detection plate 235 and the rotation amount detection sensor 9 is maintained at a fixed speed that is faster than the transport speed on the external transport path 50 by a predetermined amount (e.g., 5%). For this reason, it is possible to safely draw out the bills S that have been fed from the conveyor belt 50 through the inlet/outlet 2 to the inside. That is, the fact that the conveyance speed on the reception side is slightly faster than the conveyance speed on the conveyance side when the banknotes S are being conveyed makes it possible to stably perform conveyance.

In addition, the control unit C controls the rotational speed of the motor 39 so that the conveying speed of the tape T detected by the rotation amount detection plate 235 and the rotation amount detection sensor 9 is maintained at a fixed speed that is slower by a predetermined amount (e.g., 5%) than the conveying speed on the external conveying path 50. For this reason, the bills dispensed to the transport path 50 can be securely conveyed onto the transport path 50.

In addition, a rotation amount detection plate 235 and a rotation amount sensor 9 are arranged on the bottom roller 4, the bottom roller 4 being a feed roller provided at the inlet/outlet 2 and crushing the tape T and the banknotes S together. For this reason, the arrangement of the rotation amount detection plate 235 and the rotation amount detection sensor 9 can be easily performed, and the conveying speed of the tape T can be easily and accurately measured. It is also possible for the material for the outer circumferential surface, that is, for at least a part of the bottom roller 4, to be a material with a high coefficient of friction, such as urethane rubber. If this type of structure is used, even if a speed change such as a rapid rise in speed or a rapid fall in speed occurs in the tape T conveyed by contact with the bottom roller 4, it is possible to prevent the bottom roller 4 from slipping with respect to the tape T and to limit any speed difference therebetween, and it is possible to make the conveyance of the tape T more stable.

It is also possible to count the number of driving pulses of the motor 39 and accumulate the number of pulses using the control unit C each time a winding operation or an unwinding operation is performed on the tape T, then store it in the storage unit 250, and then repeat this fact, thereby calculating and detecting the dispensing position of the tape T. By using such a structure, it is possible to accurately detect the dispensing end of the tape T and the point also adjacent to the end, using the count value of the number of pulses, in the winding operation. However, the dispensing position of the tape T is detected only in a method when the winding operation and the unwinding operation of the tape T are normally performed. If there is a banknote jam or the banknote collection drum 10 or the tape winding drum 12 is manually rotated by an operator, it is no longer possible to accurately detect the dispensing position of the tape T. Accordingly, in this case, it is sufficient if the dispensing position of the tape T is detected by the hardware-based detection described in the present embodiment.

The paper sheet storing and dispensing apparatus 1 of the present embodiment can be used for a storage portion such as in an automatic teller machine.

While preferred embodiments of the invention have been described and illustrated above, it should be understood that these are merely exemplary of the invention and are not to be considered as limiting. Additions, omissions, substitutions, and other modifications can be made without departing from the spirit or scope of the present invention. Accordingly, the invention is not to be seen as limited by the foregoing description, but is only limited by the scope of the appended claims.
