[Prior art]
2. Description of the Related Art A banknote deposit machine that performs a bill depositing process is conventionally known. In general, a banknote depositing machine pulls in banknotes that are collectively put into a banknote depositing port, separates the individual banknotes one by one, and sequentially feeds out the banknotes. Discriminating unit that discriminates one by one in the middle of the transport path, if the deposited bill is an inappropriate bill, sorts the inappropriate bill into the deposited bill return path, and identifies When a bill is not included, it has the functions of a branching section that permits entry into the bill temporary storage path, and a temporary storage that temporarily accumulates banknotes for collective return or storage in the storage.
[0003]
As a temporary storage used in such a banknote deposit machine, there is, for example, one having a structure shown in FIGS. 39, 40 and 41 below.
FIG. 39 is an explanatory view of a main part showing an example of a conventional temporary storage. The illustrated temporary storage is a so-called stacking car system, in which a stacking car 102 around which a plurality of blades 101 are provided, a transport roller 104 for feeding bills 103 to the stacking car 102, and a temporary storage provided below the stacking car 102. It is composed of a transport belt 105 that has been stacked, a banknote stopper 106 that extracts banknotes from the stacking vehicle 102, and a belt 107 that is used to bundle and transport stacked banknotes.
[0004]
The accumulation vehicle 102 is rotating clockwise. The bills 103 conveyed in the short direction by the conveying rollers 104 are fed between the blades 101 and conveyed while being held between the blades 101. When the leading end of the bill 103 reaches the bill stopper 106, the bill 103 is extracted from between the blades 101 and dropped on the transport belt 105. The upper part of the transport belt 105 constitutes a banknote stacking unit, and the banknotes 103 transported here are sequentially stacked. The temporarily stacked banknotes are pressed from above by tilting the belt 107 in the direction shown by the arrow in the figure, and are transported collectively while being sandwiched by the transport belt 105.
[0005]
FIG. 40 is an explanatory view of a main part showing another example of the conventional temporary storage. The temporary storage shown in the drawing is a so-called impeller (concrete) type, in which a transport roller 112 around which several blades 111 are provided, and a transport roller for carrying the bills together with the transport roller 112 into the temporary storage. 113, a belt 114 used when collectively transporting the stacked banknotes, a stage 116 movable vertically and having transport rollers 115a, 115b, 115c, and a belt 116 formed between the belt 114 and the stage 116. And a bill holding member 118 whose free end presses the stage 116 with its own weight on the stacking portion 117.
[0006]
The bills transported in the longitudinal direction by the transport rollers 112 and 113 are sent to a stacking unit 117 formed between the belt 114 and the stage 116. At this time, the leading end of the bill slides between the bill holding fixture 118 and the stage 116. When the bill passes through the transport rollers 112 and 113, the trailing end is beaten downward by the blade 111. As a result, the trailing end of the bill is always pushed down, so that a space is secured above the accumulated bills, and the leading end of the next entering bill collides with the trailing end of the already accumulated bills. Disappears. When the stacking of the banknotes is completed, the stage 116 moves up and presses the stacked banknotes against the belt 114. By driving the belt 114 in such a state, the bills sandwiched therebetween are conveyed at once.
[0007]
FIG. 41 is an explanatory view of a main part showing still another example of a conventional temporary storage, in which (A) shows a view from the direction in which bills are conveyed, and (B) shows a view from the lateral direction. FIG. The illustrated temporary storage is called a pusher system, and includes a pusher 121 that reciprocates up and down, a conveyor belt 122 that conveys bills, and a bill storage unit that stores conveyed bills one by one. The bill receiving device 124 includes a bill receiving member 124, a conveyor belt 126 that constitutes a bill stacking unit 125 below the bill storage unit 123, and a stage 127 that can move up and down.
[0008]
When stacking bills, the stage 127 has been moved up to just below the bill receiving bracket 124. First, in a state where the pusher 121 is in the upper position, when the bills are conveyed one by one from the direction of the arrow 128 by the conveyance roller 122, the bills are received by the bill receiving fittings 124 at both edges in the conveyance direction. The paper money is stored in the paper money storage part 123 in the form. Next, the banknotes stored in the banknote storage unit 123 are pushed down by the pusher 121, and are pushed into the banknote stacking unit 125 through the central opening of the banknote storage unit 123, and are placed on the transport belt 126. Be accumulated. Then, the pusher 121 is raised to the original position, and waits for the next banknote stacking operation. By repeating such an operation, the transported banknotes are stacked one by one on the banknote stacking unit 125 by the pusher 121. When the predetermined stacking is completed, the stage 127 is lowered to the stacked banknotes, and the banknotes are sandwiched between the stage 127 and the transport belt 126. By driving the conveyor belt 126 in this state, the stacked banknotes are conveyed collectively.
[0009]
[Problems to be solved by the invention]
However, in the conventional temporary storage, first, in the stacking vehicle system, bills are inserted between the blades of the stacking vehicle, and the blades hold and convey the bills with frictional force. In some cases, the paper may not be properly inserted between the blades, or may fall out of the space between the blades during transportation and not be collected at a correct position. In particular, a worn and crumpled or broken banknote has a weak waist, so that the banknote may not be properly pushed between the blades and may not be correctly conveyed to the stacking position.
[0010]
In addition, in the impeller (tacking) method, since the next bill is conveyed in a state where the next bill slides on the surface of the accumulated bill, if there is a fold in a corner of the already accumulated bill, the next bill is broken. In some cases, the transfer operation may be interrupted by colliding with the portion, and it may not be possible to accumulate. In addition, since bills of different sizes are mixed in foreign (outside of Japan) bills, for example, when a short bill is conveyed, the blade may not be able to hit the trailing end of the bill. For this reason, if there are banknotes stacked with the back end warped upward without being beaten, the banknotes conveyed next may collide and be incorrectly stacked.
[0011]
Furthermore, in the pusher system, the banknotes carried into the storage unit are sent one by one to the stacking unit by the reciprocating motion of the pusher, so that the stacking process cannot be performed at high speed. There is a problem in that a large installation space is required for reciprocating the prepared pusher, and it is difficult to reduce the size.
[0012]
The present invention has been made in view of such a point, and a medium holding device capable of securely taking in and accumulating media such as a weak banknote, a banknote having a bent corner, and a banknote having a greatly different size. The purpose is to provide.
[0013]
[Means for Solving the Problems]
According to the present invention, in a medium holding device that receives and holds at least one medium conveyed individually, and discharges the held medium collectively later, the medium holding device is rotatable from a medium standby position to a medium release position. An integrated vehicle having a drum-like shape mounted on the vehicle and having a groove opening at an outer peripheral surface corresponding to the medium carry-in position when the medium is at the medium standby position and for introducing a leading end portion of the medium carried in A clamper that clamps a leading end portion of the medium introduced into the groove, opens at the medium opening position of the accumulation vehicle, and a medium accumulation unit that accumulates the medium opened at the medium opening position. And a medium holding device provided with:
[0014]
According to the above configuration, when the medium is carried in, the leading end of the medium is first introduced into the groove of the accumulation vehicle stopped at the medium standby position. The leading end of the medium introduced into the groove is clamped by the clamper. When the accumulation wheel rotates while holding the leading end of the medium, the medium is drawn into the medium accumulation section from the leading end. The stacking vehicle pulls the medium to the medium stacking section while holding the leading end of the medium with the clamper, so in the transfer process for stacking, the front end of the medium is not blocked by something in the middle of the transfer and clogged. The sheet is reliably transported to the medium release position. When the clamper unit opens the leading end of the medium at the medium release position, the conveyance of the medium by the accumulation vehicle ends, and the medium is left in the medium accumulation unit. In the same manner, the medium conveyed next is drawn into the medium stacking section with the leading end portion sandwiched, and the operation of releasing the sandwiching at the medium release position is repeated. And stays at the medium release position in a state of contact with the medium, and is aligned and collected in the medium collecting section.

And a merging unit 8 where the banknotes returned in the branching unit 5 and the temporary holding unit 6 merge with each other.
[0017]
The operation of the banknote deposit machine 1 having such a configuration will be described focusing on the flow of banknotes. First, when one or a plurality of bills are inserted into the deposit / return unit 2 (arrow 9a), the bills are collectively transported to the separation unit 3 (arrow 9b). In the separation unit 3, a plurality of banknotes are separated one by one and sequentially fed to the discrimination unit 4 (arrow 9c). The discriminating unit 4 performs denomination determination, counting for each denomination, true / false determination, appropriateness determination of the separated transport state, and the like for the input bill, and outputs the bill for which the determination has been completed (arrow 9d). The branching unit 5 performs a switching operation of the bill conveyance path according to the determination result of the discrimination unit 4. If the determination result is affirmative, the branching unit 5 performs switching control of the transport path in a direction in which the bill is allowed to enter the temporary holding unit 6 (arrow 9e). Is controlled in the direction passing through the arrow (arrow 9f). The bill that has proceeded to the merging section 8 is conveyed to the deposit / return section 2.
[0018]
The bills conveyed to the temporary holding unit 6 are sequentially aligned and accumulated, and when a predetermined accumulation is completed, the accumulated bills are output collectively. Thereafter, the transport direction of the bill is determined according to the confirmation of the depositor. That is, when a storage command is issued, the banknotes output collectively are bundled and stored in the banknote storage 7 and stored (arrow 9g). It is directed in the direction and is conveyed to the deposit / return unit 2 (arrow 9h).

Is determined to be introduced into the groove 14 after passing through the position.
[0030]
Next, the stacking / holding operation and the unloading operation of banknotes in the temporary holding unit 10 will be described. First, the stacking / holding operation of the temporary holding unit 10 will be described with reference to FIGS. 5 to 11. In these figures, only the elements related to the description of the operation will be described with reference numerals and arrows indicating the operation direction. .
[0031]
FIG. 5 is a side cross-sectional view showing a state in which the banknotes are accumulated in the temporary holding unit. FIG. 5 shows a state in which a bill P determined to be normal in a discrimination unit (not shown) is conveyed by the bill carry-in unit 13 from the left in the drawing. At this time, the stacking car 11 is stopped at the illustrated rotation position where the groove 14 is open to the bill carry-in portion 13, and the roller 21 is riding on the cam 23 so that the clamper 15 is moved out of the groove 14. Have been evacuated.
[0032]
FIG. 6 is a side cross-sectional view showing a state in which bills are carried into the groove of the stacking vehicle. In FIG. 6, the bill P is carried into the groove 14 of the stacking car 11 by the bill carry-in section 13, and at this time, the light emitted from the light emitting section 37 and received by the light receiving section 38 is blocked by the bill P. Is detected, and the carry-in of the bill P is detected. After a predetermined time from this detection, that is, at the timing when the leading end portion of the banknote P has advanced deeper than the clamper 15, the accumulation vehicle 11 is started to rotate clockwise in the figure by a motor (not shown) or the like.
[0033]
FIG. 7 is a side sectional view showing a state in which a bill is clamped. 7, when the roller 21 of the arm 16 is separated from the cam 23 by the rotation of the accumulation wheel 11, the arm 16 is rotated clockwise around the support shaft 17 by the urging force of the tension spring 19, and the clamper 15 is moved. It enters into the groove 14. As a result, the banknotes P carried into the groove 14 are sandwiched between the upper inner wall of the groove 14 and the clamper 15 and are transported together with the rotating accumulation wheel 11. At this time, in order to prevent the bill P from coming off the clamper 15, the peripheral speed on the outer periphery of the stacking vehicle 11 is set to be the same as or slightly lower than the transport speed of the bill input unit 13. As a result, although the banknote P may be slightly bent during transportation, the banknote P is not pulled by the banknote carry-in portion 13 and the clamper 15, so that the banknote P does not come off or is damaged from the clamper 15. . In this embodiment, the outer peripheral speed of the stacking vehicle 11 is set to a speed that is about 5% lower than the transport speed of the bill input unit 13.
[0034]
FIG. 8 is a side sectional view showing a state immediately before the clamp of the bill is released. In FIG. 8, when the stacking wheel 11 is further rotated and the leading end of the bill P sandwiched by the clamper 15 approaches the restricting portions 24 a to 24 d of the stopper 24, the roller 21 comes into contact with the cam 23 again. Then, the roller 21 rides on the cam 23, and the arm 16 is rotated counterclockwise around the support shaft 17 against the pulling force of the tension spring 19.
[0035]
FIG. 9 is a side sectional view showing a state in which a banknote is restricted by a stopper. In FIG. 9, since the clamper 15 is retracted from the inside of the groove 14 by the rotation of the arm 16 in the counterclockwise direction, the bill P is released from being pinched and is in a free state. The movement of the banknote P in the free state is restricted by the restricting portions 24a to 24d of the stopper 24, and the banknote P remains in the holding space S.
[0036]
FIG. 10 is a side sectional view showing a state where bills are accumulated in the holding space. In FIG. 10, when the accumulation wheel 11 further continues to rotate, the banknotes P, the leading ends of which are regulated by the regulating portions 24 a to 24 d of the stopper 24, come out of the groove 14. At this time, the tip of the gate 31 is configured to lightly hold the bill P from below. When the banknote P further rotates, the radius of the outer peripheral surface of the stacking vehicle 11 constituting the holding space S gradually increases with the rotation, so that the tip of the banknote P coming out of the groove 14 at the position of the regulating portions 24a to 24d of the stopper 24 is The bill P is moved downward by the outer peripheral surface of the accumulation vehicle 11 and is pushed toward the guide plate 26 in the holding space S.
[0037]
FIG. 11 is a side sectional view showing a state where the accumulation vehicle has returned to the accumulation standby state. In FIG. 11, in a state where the banknotes P are held in the holding space S, the stacking vehicle 11 stops at the position where the groove 14 is opened toward the banknote loading path 13, and is in a stacking standby state. By repeating the above-described operations from FIG. 5 to FIG. 11, a plurality of bills can be accumulated and retained in the retaining space S. At this time, since the portion with the groove 14 holding the bill, that is, the outer peripheral surface of the stacking car 11 having the largest radius starts to rotate in the holding space S, the outer peripheral surface of the portion with the groove 14 becomes The bills P that have already been stacked are advanced while being pushed in the direction of the guide plate 26. As a result, a space for accumulating in the holding space S is secured while the banknotes P are being conveyed. Therefore, during conveyance of the holding space S, the friction between the banknotes being conveyed and the banknotes already accumulated is reduced, and In addition, the bill does not come off from being clamped by the clamper 15.
[0038]
Next, with reference to FIG. 12 to FIG. 14, an operation of unloading the stacked and reserved banknotes will be described.
FIG. 12 is a side sectional view showing a state in which a plurality of bills are accumulated in the holding space. FIG. 12 shows a state after the stacking of the banknotes is completed and the stacking car 11 is rotated to the position of the stacking standby state, and is formed by the outer peripheral surface of the stacking car 11 and the guide plate 26. A plurality of banknotes P are stored in the storage space S. At this time, the plurality of banknotes P are aligned with their tips abutting on the restricting portions 24a to 24d of the stopper 24. The tip of the gate 31 is slightly pushed down due to the rigidity of the accumulated banknotes P on hold.
[0039]
FIG. 13 is a side sectional view showing a state immediately before carrying-out of a reserved banknote. In FIG. 13, when receiving a command to enter or return a reserved banknote, the stopper 24 is driven to rotate counterclockwise around the support shaft 25 by an actuator (not shown) or the like, thereby regulating the unloading direction of the banknote P. Is released. The support plate 28 provided on the back surface of the guide plate 26 is also driven to rotate clockwise around the support shaft 30 by an actuator (not shown) or the like. Thus, the pressing roller 27 supported by the support plate 28 presses the bills P accumulated in the holding space S, and sandwiches the bills P between the pushing roller 27 and the accumulation wheel 11.
[0040]
FIG. 14 is a side sectional view showing a state in which a reserved banknote is being carried out. When the banknotes P are carried out, first, the storage / return transport unit 34 is driven so as to carry out the banknotes P in the returning direction, and then the stacking vehicle 11 is rotated clockwise. Since the pressing roller 27 rolls while pressing the banknote P against the outer peripheral surface of the stacking vehicle 11, the banknote P enters and returns with the rotation of the stacking vehicle 11 due to the friction between the outer peripheral surface of the stacking vehicle 11 and the banknote P. It is transported in the direction of the transport unit 34. Here, when the trailing end of the banknote P carried out from the holding space S passes through the gate 31, the storage / return transport unit 34 performs a transport operation according to a command for the stacked banknotes P. In other words, when the command is storage, the storage / return transport unit 34 reverses the driving direction and unloads the banknote P in the storage direction, that is, the direction toward the banknote storage 7. If the command is a return, the storage / return transport unit 34 carries out the banknote P in the return direction, that is, the direction of the storage / return unit 2 without changing the driving direction.
[0041]
Next, a description will be given of a second embodiment of the temporary holding section in which the bill clamping force is improved.
FIG. 15 is an enlarged side view of a main part of the temporary holding unit according to the second embodiment. In FIG. 15, the same elements as those of the first embodiment shown in FIG. 1 are denoted by the same reference numerals, detailed description thereof will be omitted, and only characteristic parts will be described.
[0042]
In the groove 14 of the integrated vehicle 11, a friction material 39 having a high friction coefficient, for example, made of rubber is embedded in an inner wall portion of the groove 14 facing the damper 15. Thereby, when the clamper 15 clamps the bill P carried into the groove 14, the friction material 39 improves the clamping force of the bill P by the clamper 15, thereby stabilizing the stacking operation. That is, when the banknotes P are accumulated in the storage space S, when the leading end of the transported banknotes P is clamped and drawn into the storage space S, the space between the stacked banknotes P and the transported banknotes P is increased. A large resistance will be generated. Therefore, by providing the friction material 39 at a position facing the clamper 15, a force enough to overcome the resistance can be easily obtained.
[0043]
In the example of FIG. 15, the friction material 39 is provided on the inner wall of the groove 14. However, the friction material may be provided on the tip of the clamper 15 which enters the groove 14, or the inner wall of the groove 14 may be provided. And the tip of the clamper 15.
[0044]

In FIGS. 16 and 17, the same elements as those in the first embodiment shown in FIG. 1 are denoted by the same reference numerals, detailed description thereof will be omitted, and only characteristic parts will be described. explain.
[0045]
The friction material 39 is formed integrally with convex portions 39a and 39b at the end opposite to the end facing the clamper 15. A hole 40 is formed in the inner wall portion of the groove 14 of the integrated vehicle 11 facing the clamper 15 so as to match the shape of the friction material 39. The friction material 39 is fixed to the accumulation wheel 11 by being fitted into the hole 40. The fitting of the friction material 39 is performed by inserting the friction material 39 from the lateral direction of the integrated vehicle 11 as shown in FIG. The convex portions 39a and 39b of the friction material 39 prevent the friction material 39 from coming off in the direction of the clamper 15. Further, the friction material 39 is formed of a material such as elastic vulcanized rubber, preferably urethane rubber, and at least the outer dimensions of the convex portions 39a and 39b are adjusted to the inner dimensions of the holes 40 into which the convex portions 39a and 39b are fitted. Slightly larger than As a result, the friction material 39 mounted on the integrated vehicle 11 is fixed to the hole 40 by press-fitting, so that the friction material 39 does not easily come out of the hole 40 in the insertion direction.
[0046]
In this way, the friction material 39 having the convex portions 39a and 39b for retaining is fitted to the hole 40 formed in the inner wall portion of the groove 14 of the accumulation wheel 11 by press-fitting, so that the friction material 39 is fixed to the accumulation wheel 11. did. As a result, during operation of the banknote deposit machine, paper dust or oil or the like adheres to the friction material 39, or the material constituting the friction material 39 deteriorates, so that the friction coefficient of the friction material 39 with respect to the banknote P decreases. Even if the stacking operation becomes unstable, the friction material 39 can be easily replaced, and the banknote deposit machine can be restored in a short time. In addition, even in the case of overhaul, the processing can be performed with the minimum required number of replacement units, which is economic.
[0047]
FIG. 18 is an enlarged side view of a main part of the temporary storage unit according to the fourth embodiment, and FIG. 19 is an enlarged perspective view of a main part of the temporary storage unit according to the fourth embodiment. In FIGS. 18 and 19, the same elements as those in the first embodiment shown in FIG. 1 are denoted by the same reference numerals, detailed description thereof will be omitted, and only characteristic parts will be described. explain.
[0048]
The friction material 39 is formed integrally with a convex portion 39c having a circular cross section at the end opposite to the end facing the groove 14 of the accumulation wheel 11. A hole 41 is formed in the clamper 15 in a central portion on the side facing the groove 14 of the accumulation wheel 11 so as to match the shape of the friction material 39. The friction material 39 is fixed to the clamper 15 by fitting into the hole 41. The fitting of the friction material 39 is performed by inserting the friction material 39 from the side of the clamper 15 as shown in FIG. The convex portion 39c of the friction material 39 prevents the friction material 39 from coming off in the direction of the groove 14. Further, the friction material 39 is molded from a material such as elastic vulcanized rubber, and at least the outer dimension of the convex portion 39c is slightly larger than the inner dimension of the hole 41 into which the convex portion 39c is fitted. . As a result, the friction material 39 is pressed into the hole 41, so that the friction material 39 does not easily come out of the hole 41 in the insertion direction. Thereby, the replacement of the friction material 39 is facilitated, and the processing can be performed inexpensively and in a short time.
[0049]
Next, a description will be given of a fifth embodiment of the temporary holding unit that more reliably clamps bills with the clamper 15.
FIG. 20 is a partially cutaway perspective view of the temporary holding unit according to the fifth embodiment. 20, the same elements as those in the first embodiment shown in FIG. 1 are denoted by the same reference numerals, and detailed description thereof will be omitted. Only characteristic parts will be described.
[0050]
According to the temporary holding section shown in FIG. 20, the connecting shaft 20 penetrating through the holes formed in the accumulation vehicles 11a to 11c is connected to the arms 16a and 16c of the accumulation vehicles 11a and 11c arranged on both sides. Is fixed, but is not fixed to the arm 16b of the integrated vehicle 11b arranged at the center. That is, a hole 50 having a diameter larger than the diameter of the connection shaft 20 is formed in a corresponding position of the arm 16b through which the connection shaft 20 passes, and the connection shaft 20 is loosely inserted into the hole 50. As a result, the movement of the connecting shaft 20 is transmitted to the center arm 16b through the large hole 50, so that the clamper 15b operates differently from the clampers 15a and 15c of the arms 16a and 16c on both sides.
[0051]
Next, the stacking / holding operation of banknotes in the temporary holding section will be described. Since the basic operation is the same as that of the temporary holding section of the first embodiment, here, the characteristic operation is described. Will be described only.
[0052]
FIG. 21 is a side view showing a stacking standby state of banknotes of the stacking vehicle arranged at the center. When the temporary holding unit is in the banknote stacking standby state, the stacking vehicle 11b is stopped at the illustrated rotation position where the groove 14b is opened so that the banknotes conveyed from the banknote carry-in unit 13 are received straight. Further, the rollers 21 provided at both ends of the connecting shaft 20 are in a state of riding on the cam 23, and therefore, the arm 16b counterclockwise around the support shaft 17 against the pulling force of the pulling spring 19b. The clamper 15b is urged and retracts the clamper 15b from inside the groove 14b. However, since the diameter of the hole 50 formed in the arm 16b is larger than the diameter of the connecting shaft 20, the clamper 15b is closer to the groove 14b than the other clampers 15a and 15c by half of the difference. Has stopped.
[0053]
FIG. 22 is a side view showing a bill clamp state of the stacking vehicle arranged at the center. When the banknote P is carried into the groove 14b of the stacking car 11b by the banknote carry-in section 13, a predetermined time after that, the stacking car 11b is started to rotate clockwise in the figure by a motor (not shown) or the like. Then, the rollers 21 provided at both ends of the connection shaft 20 are separated from the cam 23, the arm 16b is rotated clockwise around the support shaft 17 by the urging force of the tension spring 19b, and the clamper 15b is inserted into the groove 14b. storm in. As a result, the bill P carried into the groove 14b is sandwiched between the upper inner wall of the groove 14b and the clamper 15b, and is transported integrally with the rotating accumulation wheel 11b. At this time, the arm 16b is not in contact with the connecting shaft 20, so that the clamper 15b generates an independent holding force of the banknote P which is not restricted by the other clampers 15a and 15c. Thereby, the bill P is more reliably clamped, and the bill P does not come off the clamper 15 during the stacking / reserving operation, and no jam occurs.
[0054]
Next, a description will be given of a sixth embodiment of the temporary holding unit configured to stabilize the accumulation state of banknotes.
FIG. 23 is a side cross-sectional view of the temporary holding unit according to the sixth embodiment. In FIG. 23, the same elements as those in the first embodiment shown in FIG. 1 are denoted by the same reference numerals, detailed description thereof will be omitted, and only characteristic parts will be described.
[0055]
According to the temporary holding section shown in FIG. 23, a movable guide plate 51 is provided at a right position in the drawing of the collecting vehicle 11 at a predetermined interval from the outer peripheral surface of the collecting vehicle 11. The movable guide plate 51 is formed in an arc shape having a diameter larger than the outer circumferential circle of the integrated vehicle 11, and bearing pieces 52 are provided at both ends of an upper edge portion thereof. Shafts 53 whose both ends are fixed to the side plates 22a and 22b are passed through the bearing pieces 52, and the movable guide plate 51 is suspended from the shaft 53 so as to be swingable about the shaft 53. As a result, the thickness of the stacked banknote changes according to the number of stacked banknotes by the movable guide plate 51, the outer peripheral surface of the stacking vehicle 11, the side plates 22 a and 22 b, and the restricting portions 24 a to 24 d of the stopper 24. The storage space S is formed. Further, on the rear side of the movable guide plate 51, a movable guide plate position sensor 54 is provided at a predetermined interval from the rear surface. The movable guide plate position sensor 54 is preferably a reflection-type optical sensor that responds when the movable guide plate 51 approaches a certain distance. However, other non-contact sensors such as a proximity sensor using a magnetic property and a photo interrupter are used. Contact sensors may be used. The output of the movable guide plate position sensor 54 is connected to a control circuit (not shown) that controls the operation of the temporary holding unit.
[0056]
FIG. 24 is a side cross-sectional view of the temporary holding unit according to the sixth embodiment showing the state of stacking banknotes. When bills are not accumulated in the holding space S, the movable guide plate 51 is suspended from the shaft 53 by its own weight, and is closest to the outer peripheral surface of the accumulation vehicle 11. When the bill is drawn into the holding space S in this state, the bill is not affected by the state, that is, even if the bill is wrinkled, creased, or curled, by the accumulation wheel 11 and the movable guide plate 51. Since the bills pass through the narrowed gap and are accumulated, the bills do not accumulate in the holding space S in a curled state, for example.
[0057]
When the banknotes are accumulated in the holding space S and the thickness of the banknotes P is equal to or larger than the gap between the stacking vehicle 11 and the movable guide plate 51 at the time of non-accumulation as shown in the drawing, the banknotes P are removed from the movable guide plate 51. I will push in the direction. Then, the bills P receive a pressing force in the appropriate thickness direction from the movable guide plate 51, and the stacking state is stabilized.
[0058]
When the stacking continues and the number of stacked sheets increases, the movable guide plate 51 rotates around the shaft 53 in a direction away from the stacking vehicle 11 accordingly. Since the rotation position of the movable guide plate 51 moves in accordance with the thickness of the stacked bills, it is possible to estimate the thickness of the stacked bills from the rotation position. The rotational position is detected by the movable guide plate position sensor 54. As described above, the movable guide plate position sensor 54 monitors the thickness of the stacked banknotes and, when detecting the predetermined thickness of the stacked banknotes, notifies a control circuit (not shown). Then, the control circuit recognizes that the thickness of the stacked banknote has become equal to or greater than the thickness that can be transported after the temporary holding unit, stops the stacking operation, and performs the next process. This makes it possible to prevent troubles during the transportation of the stacked banknotes.
[0059]
Next, a description will be given of a seventh embodiment of the temporary holding unit configured to urge the movable guide plate 51 in the direction of the accumulation vehicle 11.
FIG. 25 is a partially cutaway perspective view of the temporary holding unit according to the seventh embodiment. Since the configuration shown in FIG. 25 is generally the same as that of the first embodiment shown in FIG. 3, detailed description thereof will be omitted, and only characteristic portions will be described.
[0060]
According to the temporary holding unit shown in FIG. 25, the movable guide plate 51 arranged at a predetermined distance from the outer peripheral surface of the integrated vehicle 11 at the right position in the drawing of the integrated vehicle 11 has the outer circumferential circle of the integrated vehicle 11. A bearing piece 52 is formed in an arc shape having a larger diameter, and a shaft 53 having both ends fixed to the side plates 22a and 22b is passed through both ends of the upper edge thereof. A torsion coil spring 55 is mounted on the shaft 53. One end of the torsion coil spring 55 is locked to a stopper 56 provided on the side plate 22b, and the other end is locked to the movable guide plate 51 so as to constantly bias the movable guide plate 51 in the direction of the integrated vehicle 11.
[0061]
Due to the urging force of the torsion coil spring 55, the bill holding space S formed by the movable guide plate 51, the outer peripheral surface of the accumulation wheel 11, the side plates 22a and 22b, and the restricting portions 24a to 24d of the stopper 24, The gap in the thickness direction of the bill is always kept to a minimum. Therefore, in the holding space S, the stacked bills are constantly urged toward the outer peripheral surface of the stacking vehicle 11 by the movable guide plate 51. However, the banknotes are not curled and held in the holding space S, and the banknote stacking / holding operation is performed in a state of being aligned along the outer peripheral surface of the stacking vehicle 11.
[0062]
Next, a description will be given of an eighth embodiment of the temporary holding unit in the case where a sensor for monitoring the thickness of the stacked banknotes is provided at another position.
FIG. 26 is a side sectional view of a temporary storage section according to the eighth embodiment. FIG. 26 shows an example of a configuration having a fixed holding space S, but has a movable holding plate and a variable holding space S in which the space in the thickness direction changes according to the thickness of the bill. May be. Here, only the characteristic portions of the present embodiment will be described.
[0063]
According to the temporary holding section shown in FIG. 26, a gate 31 is provided near the lower end of the guide plate 26 so as to be swingable on the shaft 32 and urged clockwise by a tension spring 33. However, a gate position detecting sensor 37 for detecting the movement of the gate 31 is disposed below the position. The gate position detecting sensor 37 is connected to a control circuit (not shown).
[0064]
The tip of the gate 31 is located at a position inside the outer periphery of the accumulation vehicle 11 when there is no accumulation banknote in the holding space S, and when there is an accumulation banknote, the accumulated banknote is placed on the outer peripheral surface of the accumulation vehicle 11. Always in a lightly pressed state. The gate 31 rotates in a direction away from the accumulation vehicle 11 as the thickness of the accumulated bills increases. Since the distance between the tip of the gate 31 and the outer peripheral surface of the stacking car 11 is substantially equal to the thickness of the stacking bill at the time of the return / storage operation, the thickness of the stacking bill is estimated by detecting the position of the gate 31. It is possible. The position is detected by a gate position detecting sensor 37 using the gate 31 as a thickness detecting arm.
[0065]
When the thickness of the stacked bill reaches a predetermined thickness, that is, the maximum value of the transportable thickness, the gate position detecting sensor 37 detects the thickness and notifies a control circuit (not shown). Upon receiving the notification from the gate position detection sensor 37, the control circuit stops the accumulation operation of the temporary holding unit and performs the following processing. As described above, the gate position detection sensor 37 monitors the thickness of the stacked banknotes, and stops the stacking operation of the banknotes when the predetermined thickness of the stacked banknotes exceeds the transportable thickness. It is possible to prevent trouble at the time.
[0066]
Next, a description will be given of a ninth embodiment of a temporary holding unit having a function of manually removing jammed banknotes when a banknote jam occurs during the stacking operation.
FIG. 27 is a side cross-sectional view of the temporary storage section according to the ninth embodiment, and FIG. 28 is a vertical cross-sectional view of the temporary storage section taken along line bb in FIG. 27 and 28, the same elements as those in the first embodiment shown in FIGS. 1 and 2 are denoted by the same reference numerals, and detailed description thereof will be omitted. Will be described only.
[0067]
According to the temporary holding section shown in FIGS. 27 and 28, the accumulation vehicle operating section 60 is attached to one end of the rotating shaft 12 of the accumulation vehicle 11. The stacking vehicle operation unit 60 is for manually rotating the stacking vehicle 11 during maintenance work such as removing jammed banknotes when a banknote jam occurs during the stacking operation, and has a built-in one-way clutch 61. . The one-way clutch 61 is mounted between the accumulation vehicle operation unit 60 and the rotating shaft 12 of the accumulation vehicle 11, and is rotated when the accumulation vehicle operation unit 60 is rotated in the arrow direction (clockwise direction) shown in FIG. The rotational force is transmitted to the rotating shaft 12 and acts to idle when rotated in the direction opposite to the arrow (counterclockwise direction).
[0068]
FIG. 29 is a side cross-sectional view of the temporary holding unit showing a state in which a paper jam has occurred and the stacking operation has been stopped. When a banknote jam occurs during the stacking operation and the stacking operation is stopped, the banknote P may remain clamped by the clamper 15 as illustrated. In such a case, the stacking vehicle 11 is rotated in the clockwise direction indicated by the arrow, that is, in the direction of the stacking operation by the stacking vehicle operation unit 60, and the banknotes P during the stacking operation are drawn into the holding space S. Thus, it is possible to recover from the state of the paper jam. At this time, even if the accumulation vehicle operation unit 60 is erroneously rotated in the counterclockwise direction, the accumulation vehicle operation unit 60 simply idles due to the action of the built-in one-way clutch 61, and the manual rotation drive is rotated. There is no transmission to the shaft 12. Therefore, when the operator manually drives the stacking car 11 to rotate, the stacking car 11 is rotated in the counterclockwise direction, so that the jammed banknotes are entrained and damaged, and in some cases, the banknotes are damaged. It is possible to prevent the carry-in portion 13 from being damaged or the portion constituting the outer peripheral side of the groove 14 of the integrated vehicle 11 from being broken.
[0069]
Next, a tenth embodiment of a temporary holding unit that enables a carry-out operation to be reliably performed even for a banknote that has been held in a folded state will be described.
FIG. 30 is a side cross-sectional view of the temporary holding section according to the tenth embodiment. 30, the same elements as those of the first embodiment shown in FIG. 1 are denoted by the same reference numerals, and detailed description thereof will be omitted. Only characteristic parts will be described.
[0070]
According to the temporary holding unit shown in FIG. 30, the pressing roller 27 is rotatably fixed to the support plate 28 pivotally supported on the support shaft 30 on the back side of the guide plate 26. I have. Further, the pressing roller 27 is driven to rotate counterclockwise by a rotation transmission mechanism described later. At this time, the speed (peripheral speed) in the tangential direction of the outer peripheral surface of the pressing roller 27 is set to be substantially equal to the speed in the tangential direction of the outer peripheral surface of the accumulation wheel 11.
[0071]
Here, it is assumed that the banknotes P accumulated in the holding space are in a bad state with, for example, a bent habit in the center as shown in the drawing. In such a case, if the delivery of the banknotes is dependent only on the rotation drive of the stacking car 11, the bent portion of the banknotes may be caught by the pressing roller 27, and the banknotes may not be normally discharged. 27 itself has a conveying force, and therefore, even if a banknote has a bent part, the banknote 27 can easily get over such a step and can be normally carried out. Furthermore, since the speeds in the tangential direction of the outer peripheral surfaces of the pressing roller 27 and the stacking wheel 11 are almost matched, the held banknotes can be conveyed without being shifted and kept in a bundle. Can be. Thereby, it is possible to prevent a transportation trouble when the reserved banknotes are returned in a lump or stored in the storage.
[0072]
FIG. 31 is a conceptual diagram illustrating an example of a rotation transmission mechanism in a bill discharging operation. The pressing roller 27 is driven to rotate by the driving force of a motor that drives the accumulation wheel 11. That is, the motor drive shaft 62 is configured such that the timing belt 65 is hung on the pulley 63 fixed to the rotating shaft 12 of the integrated vehicle 11 and the pulley 64 rotatably provided on the support shaft 30 of the support plate 28, so that the pulley 64 is It is configured to be driven to rotate. Further, another pulley 66 integrated with the pulley 64 is configured such that a timing belt 68 is hung on a pulley 67 rotatably supported by the support plate 28 to rotate the pulley 67. Further, a gear 69 is fixed to the pulley 67, and the gear 69 is engaged with a gear 70 fixed to the pressing roller 27. At this time, by appropriately selecting the diameters of the pulleys 63, 64, 66, 67 and the gear ratios of the gears 69, 70, the tangential speeds of the pressing roller 27 and the outer peripheral surface of the accumulation wheel 11 are made to substantially match. ing.
[0073]
At the time of banknote unloading operation, the motor drive shaft 62 is driven to rotate clockwise, so that the pulley 63 is also driven to rotate clockwise, and the accumulation wheel 11 is similarly driven through the rotation shaft 12 fixed thereto. It is driven to rotate in the circumferential direction. Further, since the pulley 64 is also driven to rotate clockwise, the pulley 66 integrated therewith is also driven to rotate clockwise, and the pulley 67 is also driven to rotate clockwise via the timing belt 68. Therefore, the pressing roller 27, which is driven to rotate via the gear 69 fixed to the pulley 67 and the gear 70 fixed to the pressing roller 27, is driven to rotate counterclockwise. Thus, since the pressing roller 27 and the stacking wheel 11 are driven to rotate in opposite directions to each other, the bills sandwiched therebetween can be reliably carried out of the temporary holding section regardless of the state of the kinks.
[0074]
Next, a description will be given of an eleventh embodiment of the temporary holding unit capable of performing the stacking operation without displacing even the banknotes stacked in a curled state.
FIG. 32 is a side cross-sectional view of the temporary storage unit according to the eleventh embodiment, and FIG. 33 is a partially cutaway perspective view of the temporary storage unit according to the eleventh embodiment. 32 and 33, the same elements as those in the first embodiment shown in FIGS. 1 and 3 are denoted by the same reference numerals, and detailed description thereof will be omitted. Will be described only.
[0075]
According to the temporary holding section shown in FIGS. 32 and 33, the gate 31 is disposed near the lower end of the guide plate 26, and the gate 31 is swingably supported on the shaft 32, and is rotated clockwise by the tension spring 33. Urged by a spring force. The gate 31 swings about the shaft 32 during the stacking operation of the banknotes, and a step 31 a is provided so that at least a part of the leading end thereof always intersects with the restricting portion of the stopper 24 in the swinging range. Has been. In accordance with this, as best shown in FIG. 33, the restricting portion is also provided so that the distal end portion of the restricting portion in the swing range of the gate 31 does not interfere with the restricting portion. A step 24e is provided, and the gate 31 and the restricting portion are in a cross-shaped form.
[0076]
FIG. 34 is a diagram illustrating a possibility that a banknote in a bad state may come out of the holding space. As shown in the drawing, for example, if there is a banknote having a bad curl at the leading end in the stacking direction, the banknote may be moved between the leading end of the gate 31 and the regulating portion of the stopper 24 during the stacking operation. The leading end of a curled bill may enter the gap. In such a case, a problem such as a bill jam may occur at the time of the bill carry-out operation. However, as shown in FIG. 32 and FIG. 33, since a part of the tip portion of the gate 31 extends earlier than the regulating portion, even if banknotes having a bad curl state are accumulated, Since the leading end of the bill does not enter the gap between the leading end of the gate 31 and the restricting portion of the stopper 24 and goes out of the holding space S, the posture of the leading end of the held bill is changed. Always stable. As a result, it is possible to eliminate the occurrence of trouble at the time of unloading, and to enhance the reliability of the banknote deposit machine.
[0077]
Next, since the stopper 24 and the pressing roller 27 have two operation modes, namely, a bill accumulation operation and a bill carry-out operation, the drive mechanisms are simplified by operating these with one actuator. A twelfth embodiment of the holding unit will be described.
[0078]
FIG. 35 is a side cross-sectional view showing a temporary holding unit in a stacking standby state according to the twelfth embodiment, FIG. 36 is a side cross-sectional view showing a temporary holding unit during a banknote stacking operation in the twelfth embodiment, and FIG. It is a sectional side view which shows the temporary holding part just before a banknote discharge in twelfth embodiment. 35 to 37, the same elements as those in the first embodiment shown in FIG. 1 are denoted by the same reference numerals, detailed description thereof will be omitted, and only characteristic parts will be described. I do.
[0079]
According to the temporary holding section shown in FIGS. 35 to 37, the tension spring 81 is hooked on the other end of the stopper 24 provided below the accumulation vehicle 11 on the opposite side to the one end constituting the regulating section. The stopper 24 is urged by a spring force so as to rotate the stopper 24 clockwise in FIG. A rotatably supported cam shaft 82 is disposed below the stopper 24 between the support shaft 25 and the end on which the extension spring 81 is hung, and the cam shaft 82 has an elliptical cam plate. 83 and a pulley 84 are fixed. The stopper 24 swings by an action of contacting and separating with the long diameter portion of the cam plate 83 accompanying the rotation of the cam plate 83.
[0080]
A pressing roller 27 is rotatably supported on a shaft 29 fixed to a support plate 28 on the rear side of the guide plate 26, that is, on the right side in FIG. 35, and the support plate 28 is swingable on a support shaft 30. Supported. A tension spring 85 is hung on the end of the support plate 28 opposite to the side where the pressing roller 27 is provided, so that the support plate 28 can be rotated clockwise in FIG. To the spring force. Further, a cam shaft 86 rotatably supported is disposed on the right side of the support plate 28 between the support shaft 30 and the end where the extension spring 85 is hooked, and the cam shaft 86 has an elliptical shape. The cam plate 87 and the pulley 88 are fixed. The support plate 28 swings by an action of contacting and separating with the long diameter portion of the cam plate 87 accompanying the rotation of the cam plate 87.
[0081]
Further, an actuator 89 is disposed at a position on the right side of the cam shafts 82 and 86. A pulley 91 is fixed to a drive shaft 90 of the actuator 89. The pulley 91 has a timing belt 92 wound around a pulley 84 disposed on the stopper 24 side and a pulley 88 disposed on the support plate 28 side. Here, as shown in FIGS. 35 and 36, when the temporary holding section is in the stacking standby state and the stacking operation state, the cam plate 83 fixed to the pulley 84 has its long-diameter portion directed downward in the figure. The cam plate 87 fixed to the pulley 88 is located at a position where its long diameter portion is directed leftward in the drawing and is in contact with the support plate 28. Also, as shown in FIG. 37, when the temporary holding unit is in the banknote unloading operation state, the cam plate 83 fixed to the pulley 84 has its long diameter portion facing upward in the figure and The cam plate 87 fixed to the pulley 88 is located at a position where its long diameter portion is directed rightward in the drawing and does not contact the support plate 28. Therefore, by driving the actuator 89 to rotate the pulley 91, the pulleys 84, 88 rotate in synchronization with the rotation, and the cam plates 83, 87 fixed to these pulleys 84, 88 rotate, respectively. The stopper 24 and the support plate 28 swing.
[0082]
Here, when the temporary holding unit is in the stacking operation state, as shown in FIG. 36, the stopper 24 is urged by the spring force of the tension spring 81 to a position where the movement of the held banknote P is regulated. Maintained in state. Further, in this state, the support plate 28 retreats the pressing roller 27 from the holding space S by the contact of the long diameter portion of the cam plate 87 so that the pressing roller 27 does not interfere with the holding banknote P.
[0083]
Further, when receiving or returning a reserved banknote, the actuator 89 is driven to rotate, and the pulleys 84 and 88 are rotated via the timing belt 92 when the operation is shifted to the operation of carrying out the reserved banknote P. I do. Then, when the cam plates 83, 87 fixed to the pulleys 84, 88 have rotated to the positions shown in FIG. 37, the positions are detected by sensors (not shown), and the rotation of the actuator 89 is stopped. As a result, the stopper 24 comes into contact with the long diameter portion of the cam plate 83 and is driven to rotate counterclockwise about the support shaft 25, whereby the restriction on the carry-out direction of the reserved banknote P is released. . At the same time, since the long diameter portion of the cam plate 87 is separated from the support plate 28, the support plate 28 is driven to rotate counterclockwise around the support shaft 30 by the spring force of the extension spring 85, whereby the support plate 28 The supported pressing roller 27 presses against the banknote P held in the holding space S, and sandwiches the banknote P between the pressing roller 27 and the outer peripheral surface of the accumulation wheel 11.
[0084]
