  By the way, some paper sheets have different sizes depending on the type. For example, when the paper sheet is a banknote like the above-mentioned patent document, the size of the banknote is the same in the short direction regardless of the denomination, but the longitudinal direction differs depending on the denomination. For this reason, in the case of a holding and stacking device having a structure for transporting in the short direction, the length of the holding space is constant, and four-type denomination mixed storage and collective payout are possible. However, if all the operations from the bill insertion to the stacking are performed in the horizontal orientation as described above, it is not preferable in the vending machine or the like in which the stacking and stacking device is required to limit the lateral width as much as possible in the installed state.

  On the other hand, in the case of a stacking and stacking device having a structure for transporting in the longitudinal direction, when a plurality of denominations are mixed and accumulated, there is a dimensional difference in the insertion direction (length direction) depending on the denomination of the banknotes as described above. When the same stacking unit is mixed and stacked, as shown in FIG. 10, when the insertion end side of the bill A is stopped by the stopper X formed at a predetermined position, the rear end side of the bill A becomes uneven. And if it is constituted so that the rear end side is struck intermittently with a sweeper Y equipped with flexible blades and retracted in the stacking direction with reference to a large denomination banknote, a denomination with a small longitudinal dimension The sweeper Y does not reach the rear end side. For this reason, when the banknotes A are mixed and accumulated, the already accumulated banknotes jump up onto the insertion part (throwing conveyance path) into the insertion space, and cause jamming by interfering with the next inserted banknote. Become.

  In this case, if the length of the blade of the sweeper Y is increased, the tapping force is weakened. Since a number of problems occur separately, it is difficult to ensure reliability.

  The present invention has been made paying attention to such a problem, and can realize an appropriate stacking state corresponding to the difference in the size of paper sheets such as banknotes, thereby effectively preventing the occurrence of jams and the like. It is an object of the present invention to newly provide a paper sheet storage and stacking device that can be prevented.

  In order to achieve this object, the present invention takes the following measures.

In other words, the paper sheet stacking and accumulating apparatus according to the present invention has a structure for loading paper sheets transported from the outside into a storage space for storing paper sheets and stacking and holding them on the storage plate. The paper sheet is provided with a movable restricting portion that can change the restriction position along the loading direction at the leading end side of the paper sheet , and by switching the restriction position of the movable restriction portion , the holding range of the paper sheet is changed to the paper sheet. A holding range switching mechanism that is variable in a predetermined direction according to the size of the paper is provided in the holding space, and the rear end side of the stored paper is placed in the paper stacking direction in the vicinity of the input / output portion of the paper A sweeper for evacuating the paper sheet, including a paper sheet identification unit for identifying the type of the paper sheet to be conveyed, and in conjunction with the identification result by the paper sheet identification unit, The lower end of the part is in close contact with the retaining plate The holding range switching mechanism changes the holding position of the movable restricting portion to change the holding range of the paper sheet in the holding space, so that the paper The end positions are substantially aligned .

  When configured in this way, when paper sheets are mixed and accumulated in one storage unit, the storage range of paper sheets in the storage space can be changed according to the size through the storage range switching mechanism. An appropriate holding state can be ensured even for paper sheets of the size. For this reason, it becomes possible to effectively cope with the interference between the already-inserted paper sheet and the next input paper sheet, the occurrence of jam, and the like caused by the irregularity of a specific part of the paper sheet. .

In addition, a paper sheet identification unit for identifying the type of paper sheet to be conveyed is further provided, and the holding range switching mechanism is linked to the identification result by the paper sheet identification unit, and the paper sheet in the holding space. Since the holding range is changed in a predetermined direction, it is possible to suitably cope with different types of paper sheets.

Also, the turned back end side of the sheet in view in particular but jamming is likely to occur, hold range switching mechanism, the regulating position modifiable movable restrictor along a charging direction to the insertion tip side of the sheet comprising a part, the rear end position of the paper sheet irrespective of the charging direction of the dimension of the paper sheet is to switch the regulating position to substantially align.

Further, in the vicinity and out of the paper sheet, since the turned back end side of the pending paper sheet is provided with a sweeper for keeping retreated to the paper sheet stacking direction, it is possible to ensure the function of the sweeper can Ru.

Further, the paper sheet input / output unit further includes an input / output unit drive mechanism for loading the paper sheet into and out of the storage space, and discharging the paper sheet, and when the paper sheet is discharged, the storage plate It is preferable that the sheet is moved to the discharge position so that the rear end side of the paper sheet can be sandwiched by the rollers constituting the input / output unit drive mechanism.
Further, the movable restricting portion hangs down from an upper unit that covers the upper portion of the retaining plate, and the retaining range switching mechanism further includes a fixed restricting portion that rises from the loading tip side of the retaining plate. When a long paper sheet is inserted, the movable restricting portion should not be hindered by the fixed restricting portion and turn up to a position where it overlaps the fixed restricting portion in a side view. Is preferred.
In order to achieve the above-described configuration effectively, it is preferable to provide a shape changing unit that deforms the paper sheets so that the cross section perpendicular to the loading direction becomes a non-linear shape when the paper sheets are loaded.

  As described above, according to the present invention, since the holding range of the holding space can be changed in a necessary direction according to the type of the inserted paper sheet, an appropriate holding state according to the type of the paper sheet is set. By realizing this, it is possible to provide an excellent paper sheet storage and stacking apparatus that can be appropriately used for heterogeneous mixed stacking without generating jam or the like.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 shows a banknote storage and stacking apparatus as a paper sheet storage and stacking apparatus according to this embodiment.

  In this case, a banknote A, which is a paper sheet inserted from a batch insertion slot 11, is passed through a banknote identification section 13 via an insertion slot 12, and the banknote A is temporarily held via a transport path 10. It has the function to convey to. The banknotes A are sequentially inserted into the holding unit 2 through the input / output unit 2x, which is also referred to as a so-called throw-in conveyance path, and the stacked banknote bundle is moved from the holding unit 2 to the input / output unit 2x at a predetermined timing as shown in FIG. Are discharged together and transferred to the adjacent stacking unit 3. In order to carry the banknote A in a limited space, the conveyance path 10 in the apparatus shown in FIG. 1 including the vicinity of the entrance / exit 2x is similar to the bent conveyance path 10x shown in FIG. There is a bend.

  3 and FIG. 4 is a side view of the holding unit 2 in which the lower unit 4 shown in FIG. 6 and the upper unit 5 shown in FIG. 7 are vertically combined as shown in FIG. Since the positional relationship of the component parts necessary for explanation is clear from each drawing, in FIG. 3 and FIG. The same applies to the other drawings.

  As shown in FIGS. 3, 5 and 6, the lower unit 4 has a unit frame 41 having a facing piece 41 a, and an end portion of the unit frame 41 is pivoted to the facing piece 41 a of the unit frame 41 via a support shaft 42 a. A retaining plate 42 that is attached and has the other end as a free end, and a lower roller unit 43 and a lower discharge roller 46 disposed on the rotating end side of the retaining plate 42 are provided. The retaining plate is also commonly referred to as a payout plate, and the discharge roller is also commonly referred to as a payout roller. The lower roller unit 43 has a plurality of (three in the figure) lower feeding rollers 44 along the axial direction of the lower roller shaft 44a, and a sweeper having flexible blades between the lower feeding rollers 44, 44. (Tapping wheel) 45 has a configuration with a shaft attached thereto.

  The retaining plate 42 is pivotally attached to the lower discharge roller 46 via a roller shaft 46a in the vicinity of the rotation end, and in the vicinity of the support shaft 42a of the retaining plate 42 in a lower adjacent position in FIG. A pressure receiving portion 42b that is urged by a vertical movement of a fork (not shown) in the accumulation portion 3 in the arrow direction is set. That is, when the banknote A is inserted, the storage plate 42 moves to the retracted position away from the insertion roller 44 as shown in FIG. 4 to FIG. 3, thereby expanding the storage space S shown in FIG. As shown in FIGS. 3 to 4, when the paper is discharged, the paper A is moved to a discharge position where it can be discharged by the lower discharge roller 46, etc. The actuating source of the storage plate 42 is also used as a fork in the accumulating unit 3, so that it is not necessary to bring a new driving source separately.

  On the other hand, as shown in FIGS. 3, 5 and 7, etc., the upper unit 5 is disposed at a position covering the lower unit 4, and includes a unit frame 51 having a facing piece 51a, An upper feeding roller 52 that is pivotally attached to the opposing piece 51a via an upper roller shaft 52a and disposed at a position corresponding to the lower feeding roller 44, and a lower discharge roller that is pivotally attached to the opposing piece 51a via a roller shaft 53a. The upper discharge roller 53 is arranged at 46 corresponding positions.

  The upper insertion roller 52 is attached to the bill A together with the lower insertion roller 44 from both sides in the thickness direction, and in this state, the bill A is transferred toward the holding space S by synchronously rotating in the reverse direction. The banknote A that has passed through the upper and lower insertion rollers 44 and 52 is thrown into the holding space S, dropped downward by the sweeper 45, and moved by the sweeper 45 toward the stacking direction so as not to interfere with the next inserted banknote A. It is struck intermittently and accumulated and held on the retaining plate 42. Thereby, space-saving and high-speed continuous integration is performed.

  Further, the upper discharge roller 53 is in a position where the rear end side of the banknote bundle can be clamped in cooperation with the lower discharge roller 46 when the holding plate 42 is pushed up as shown in FIGS. When these discharge rollers 53 and 46 are attached to both sides of the bill A and rotate synchronously in the reverse direction, the bill bundle is discharged from the holding space S to the outside. At this time, the upper input roller 52 and the lower input roller 44 rotate in the direction opposite to that at the time of input, and the banknote A sent out from the discharge rollers 53 and 46 is further led out toward the bent conveyance path 2x.

  The upper loading roller 52, the lower loading roller 44, the upper discharging roller 53, and the lower discharging roller 46 constitute a loading / unloading section drive mechanism 6 that causes a loading / unloading operation to the bill A in the loading / unloading section 2x of the holding space S. These rollers 44, 52, 46, 53 are configured to be synchronously driven by appropriate means such as a timing belt.

  In the above, when the banknotes are mixed and accumulated, the longitudinal dimension differs depending on the type of the banknotes A. Therefore, when the leading end side of the banknotes A is stopped at the same position on the holding plate 42, the position of the rear end side of the banknotes varies. . For example, a thousand yen bill and a 10,000 yen bill have a dimensional difference of about 10 mm in the longitudinal dimension. For this reason, if the holding range in the longitudinal direction is determined so that the rear end side is appropriately hit with the sweeper 45 with reference to a large denomination of 5,000 yen bill or 10,000 yen bill, When the banknote A having a small denomination is inserted, the sweeper 45 does not reach the rear end side, and interferes with the next inserted banknote A, which causes jamming.

  Therefore, in the present embodiment, the holding range switching mechanism 7 (FIGS. 5 and 8) that makes the holding range of the bill A in the holding space S variable according to the size of the bill A in order to enable the four denomination mixed accumulation. Etc.).

This holding range switching mechanism 7 has a tongue-shaped fixing restricting portion 71 that rises from the leading end side of the holding plate 42 that constitutes the lower unit 4 shown in FIG. 6, and an angle-like shape that hangs down from the upper unit 5 shown in FIG. The movable restricting portion 72 is pivotally mounted around the support shaft 72a, and the fixed restricting portion 71 is passed through the window 72c provided in a part of the hanging wall 72b while the fixed restricting portion 71 is passed. It can be rotated without interfering with the restricting portion 71. By this turning function, the movable restricting portion 72 is thrown up to a position shown in FIG. 9 that does not interfere with the restriction by the fixed restricting portion 71 and overlaps the fixed restricting portion 71 in a side view, and thus the fixed restricting portion 71 is inserted. The hanging wall 72b functions as a stopper that regulates the leading edge position a1 of the long banknote A, and the movable regulating portion 72 is pivoted and lowered to the position shown in FIG. It functions as a stopper that regulates the leading end position a2 of the short banknote A that is moved to the side closer to the sweeper than the fixing restricting portion 71 and is inserted. The lower end of the downward wall 72b is adapted to have an L-shaped bent outward, its lower end is lowered to a relatively close position without interfering on hold plate 42 by the rotation.

  Then, a switching actuator 73 that can be switched at a sufficiently high speed than the conveyance interval of the bill A is mounted at the leading end of the holding space S, and the switching actuator 73 is based on the result of denomination being discriminated by the bill identifying unit 13 in FIG. Before the bill is inserted, the support shaft 72a is driven in advance, and the movable restricting portion 72 is moved to a position corresponding to the denomination. In the present embodiment, when the inserted bill A is 1,000 yen or 2,000 yen, the movable restricting portion 72 is lowered to shorten the holding range of the holding space S, and when the bill A is 5,000 yen or 10,000 yen. The movable restricting portion 72 is raised to set the holding space S longer.

  In this embodiment, the banknote A is deformed so that the cross-section perpendicular to the loading direction is a non-linear shape when being inserted into the loading / unloading section drive mechanism 6 described above, and the deformation is released when discharged as shown in FIG. A shape changing unit 61 shown in FIG. The shape deforming portion 61 is used as a nip roller by overlapping the throwing rollers 52 and 44 in the bill thickness direction, and deforms the bill into a corrugated cross-section or the like at the time of throwing. Therefore, the retaining plate 42 and the lower roller unit 43 can be interlocked by a balance member 47 pivotally attached via a support shaft 47a.

  As described above, the banknote holding and stacking apparatus of the present embodiment has a structure for putting the banknote A conveyed from the outside into the holding space S that holds the banknote A. A holding range switching mechanism 7 for changing the holding range of A according to the size of the bill A is provided.

  For this reason, when banknotes A are mixedly inserted and accumulated in one holding section 2, by changing the holding range of banknotes A in the holding space S through the holding range switching mechanism 7, any size of banknote A Therefore, it is possible to secure an appropriate hold state. For this reason, it is possible to effectively prevent the already inserted banknote A from interfering with the next inserted banknote A to cause jamming, and to improve the reliability effectively. Further, even when the holding unit 2 and the stacking unit 3 are arranged at a plurality of locations according to the denominations, these configurations can be shared.

  In particular, it further includes a banknote identification unit 13 for identifying the denomination of the banknote A to be conveyed, and the holding range switching mechanism 7 determines the holding range of the banknote A in the holding space S in conjunction with the identification result by the banknote identification unit 13. Since it changes and it is made to switch automatically to an appropriate state according to the kind of banknote A, it can respond suitably to continuous insertion of a mixed banknote. Even when the holding unit 2 and the stacking unit 3 are provided at a plurality of locations and control is performed by sorting and transporting each denomination, automatic length sorting can be performed in the same manner as described above. Even if the denomination is changed in, this can be handled automatically.

  The holding range switching mechanism 7 includes a movable restricting portion 72 whose regulation position can be changed along the insertion direction on the insertion tip side of the bill A, and the rear end of the bill A regardless of the dimension in the insertion direction of the bill A. In order to substantially align the positions, the restriction position is switched between the fixed restriction portion 71 and the bill A is distributed to a predetermined stop position. Therefore, a jam occurs between the already inserted bill A and the next inserted bill A. It is possible to effectively avoid this, and since the rear ends are aligned at the time of discharge, the banknote bundle can be sent out in an appropriate state via the discharge rollers 53 and 46 and the input rollers 52 and 44.

  In particular, the present embodiment is provided with a sweeper 45 for retracting the inserted rear end side of the banknote A held in the banknote stacking direction in the vicinity of the banknote A input / output section. The sweeper 45 can be surely acted on the rear end of the rear end to maintain an appropriate accumulation state.

  In these, if the substantial longitudinal dimension of the banknote A is shortened due to a crease or the like, the above-described structure is not effective. However, in this embodiment, the cross section orthogonal to the insertion direction of the banknote A is not present at the time of insertion. Since the shape changing portion 61 that is deformed so as to have a linear shape is provided, the banknote A can be given a firmness and the original longitudinal dimension can be maintained, and the effects of the present invention can be exhibited accurately.

  The specific configuration of each unit is not limited to the above-described embodiment.

  For example, the sweeper can be configured to rotate in the flip-up direction.

  In the above embodiment, the banknotes are sorted in two ways, but the lengths may be sorted in three or more ways.

  Furthermore, the application target of the present invention is also applicable to a structure in which banknotes accumulated in the holding space are discharged in another direction.

  Furthermore, the applicable paper sheets are not limited to domestic banknotes and thus banknotes, and can be widely applied to general mixed accumulation of paper sheets having different longitudinal dimensions.

  Other configurations can be variously modified without departing from the spirit of the present invention.
