[0028]
Next, the configuration and operation of the recycle box 8 to which the present invention is applied will be described with reference to FIGS. 6 and 7.
[0029]
The recycle box 8 includes a stack / separation mechanism for storing and separating and feeding bills.
[0030]
The stack / separation mechanism includes a stack / feed roller 81, a pickup roller 90, a guide roller 93, a follow-up rotating backup roller 82, and a storage roller that are rotationally driven via a gear from a drive source (not shown) outside the storage. Gate roller 83 that rotates in the direction of rotation and does not rotate in the feed-out direction, brush roller 84 on the same axis as this gate roller 83 and having elastic members arranged radially about a half circumference, and at the time of separation and stacking It is attached to the separation / stack guide 85 that moves in the same axis as the gate roller 83, and is lifted up to a position that wraps with the separation / stack guide 85 at the time of stacking. A deformation additional guide 92 that is pushed under the floor plate 88 so as not to obstruct the transport bill; The upper scraping roller 91 disposed in the vicinity of the upper part of the separation / stack guide 85 and the lower scraping roller disposed in the vicinity of the gate roller 83 at the lower part of the storage unit. 89.
[0031]
Next, the bill storing operation of the recycle box 8 will be described.
[0032]
The bills are stored in a storage space surrounded by a bottom plate 88, a push plate 86, a bottom belt 87 suspended so as to support the lower surface of the bill on the upper surface from the bottom plate 88, and a separation / stack guide 85.
[0033]
The banknotes conveyed to the recycle box 8 are transformed between the rotating stack / feed roller 81 and the backup roller 82 and subsequently between the stack / feed roller 81 and the gate roller 83 rotating in the stacking direction. The additional guide 92 is lifted to enter the stack space 96. The banknotes that have entered the stack space 96 are influenced by the deformation addition guide 92, are taken along the separation / stack guide 85, and are stored in the stack space 96.
[0034]
The lower end of the stored banknote is scraped in the stacking direction by a rotating brush roller 84 to prevent interference with a subsequent banknote. The brush roller 84 is provided with brushes radially about only half a circle in order to realize a separating operation described later. In order to surely scrape out the trailing edge of the stored banknotes in the stacking direction with a brush, rotation phase control corresponding to each banknote is performed on the plush roller 84. That is, the tip of the banknote conveyed to the recycle box 8 is detected by a sensor (not shown), and the rotational speed of the brush roller 84 is increased or decreased until the detected banknote is sandwiched between the stack / feed roller 81 and the backup roller 82. By doing so, the phase alignment is realized.
[0035]
Further, the bills scraped by the brush roller 84 are configured so as not to be obstructed by the subsequent bills by entering the teeth on the outer periphery of the lower scraping roller 89 as they are.
[0036]
Furthermore, the increase of the banknotes stored in the stack space 96 is configured to be monitored by the remaining banknote detection sensors 95a and 95b. When the remaining banknote is detected, the push plate 86 and the bottom belt 87 are controlled to move in a direction in which the stored banknote is retracted from the stack space 96 by a drive source (not shown). Further, even when no remaining banknote is detected, the stack space 96 can be secured by retracting the pressing plate 86 and the bottom belt 87 in advance according to the number of banknotes taken into the stack space 96. To do.
[0037]
Further, the upper scraping roller 91 and the lower scraping roller 89 are rotated in the storing direction to support the upper and lower ends of the stored bills, thereby holding the bills in a standing posture.
[0038]
Thus, a stable stack is realized by avoiding interference between the stored banknotes in the stack space 96 and the transported banknotes transported to the stack space 96.
[0039]
Next, the banknote separation operation of the recycle box 8 will be described.
[0040]
First, the brush roller 84 rotates and is stopped and fixed at a position where a portion where no brush is disposed is exposed.
[0041]
Next, the bills stored in the stack space 96 are moved in the direction of the separation / stack guide 85 by driving the push plate 86 and the bottom belt 87 by a drive source (not shown) outside the safe. When the stored banknote moves to the separation / stack guide 85, the separation / stack guide 85 gradually moves to a position indicated by a broken line 85a, and the pickup roller 90 is exposed. When the pickup roller 90 applies a predetermined pressing force to the stored banknote, the pickup roller 90 that rotates in the feeding direction, the stack / feed roller 81 and the guide roller 93, and the built-in one-way clutch rotate in the feeding direction. The banknotes are conveyed one by one so as to prevent two-sheet feeding by the action of the gate roller 83 that does not. At this time, the guide roller 93 that rotates in the separating direction can be separated while stretching the folded folds of the bills, and the bills can be separated stably.
[0042]
The banknote handling apparatus 1 handles a single denomination in one recycle box 8 in order to take in and out an arbitrary number of banknotes handled.
[0043]
In consideration of banknote separation performance and banknote portability, the recycle box 8 includes a side plate 71 for orderly storing banknotes as shown in FIG.
[0044]
Since the width of the banknote conveyance port constituted by the stack / feed roller 81, the gate roller 83, and the brush roller 84 and the width between the side plates 71 may vary greatly depending on the banknote size, The deviation is corrected.
[0045]
Next, the configuration and operation of the displacement correction mechanism applied to the recycle box 8 in one embodiment of the present invention will be described.
[0046]
First, the configuration of the deviation correcting mechanism will be described.
[0047]
As shown in FIGS. 1 and 2, the displacement correcting mechanism of this embodiment gradually increases the width from the banknote conveyance port constituted by the stack / feed roller 81, the gate roller 83, and the brush roller 84 to between the side plates 71. A displacement correction plate 72 is provided so as to be narrowed. The displacement correction plate 72 is desirably a member having a low frictional force with respect to banknotes. In addition, as shown in FIG. 8, this deviation correction plate 72 is used to bring the deviated banknotes closer to the center and to increase the contact surface with the deviation correction sheet 73a described later. Has an oblique surface.
[0048]
Further, as shown in FIG. 2, the displacement correction mechanism in this embodiment includes a displacement correction sheet roller 73 in which at least one sheet-shaped displacement correction sheet 73 a extends from the boss portion, and a side plate 71. It is provided to be located at the same width position or outside it.
[0049]
In this embodiment, the deviation correcting sheet roller 73 is installed on a common shaft with the brush roller 84 and rotates in the same direction as the brush roller 84 during the bill storing operation. The deviation correcting sheet roller 73 functions to send the banknote in the storing direction and avoid interference with the subsequent banknote, and to function to send the banknote in the direction to correct the deviation of the banknote. The displacement correction sheet 73a is preferably made of a flexible material and has a high frictional force against the banknote.
[0050]
As shown in FIG. 8, the displacement correction sheet roller 73 is arranged so that the displacement correction sheet 73 a contacts the displacement correction plate 72 every time it rotates. Since the displacement correction sheet 73 a is flexible, when it contacts the displacement correction plate 72, it is elastically deformed toward the center of the stack space 96.
[0051]
As shown in FIG. 2, since the paper sheet stacking apparatus of this embodiment corrects the deviation of the bills in the central direction, the deviation correction plate 72 and the deviation correction sheet roller 73 are stored and separated. Install on both sides of mouth.
[0052]
Next, the operation of the deviation correcting mechanism will be described.
[0053]
The offset bill is corrected when it is taken into the stack space 96 of the recycle box 8. In the storing operation, when a bill is taken into the stack space 96, the bill released from the sandwiching force between the stack / feed roller 81 and the gate roller 83 is scraped out to the stack space 96 by the brush roller 84.
[0054]
As shown in FIG. 9, when the bill taken into the stack space 96 is displaced, the lower end is sandwiched between the displacement correction sheet 73 a and the displacement correction plate 72. As described above, the displacement correction plate 72 and the banknote have low friction, the displacement correction sheet 73a and the banknote have high friction, and the displacement correction sheet 73a has a stack space each time it comes into contact with the displacement correction plate 72. 96, the banknote sandwiched between the displacement correction plate 72 and the displacement correction sheet 73a is deformed by the displacement correction sheet 73a, that is, as the displacement correction sheet roller 73 rotates. It is fed into the stack space 96 while being corrected for displacement in the central direction of the stack space 96.
[0055]
Further, since the displacement correction sheet roller 73 is continuously rotated, the displacement correction sheet 73a is in contact with the continuously displaced banknote to correct the displacement.
[0056]
Due to the above-described function, the deviated banknote moves toward the center of the stack space 96 as long as it can be sandwiched between the displacement correction plate 72 and the displacement correction sheet 73a. The deviation is corrected until it moves to.
[0057]
The side plate 71, the displacement correction plate 72, and the displacement correction sheet roller 73 are preferably installed so that the position in the width direction of the transport path can be changed according to the size of the bill handled by the recycle box 8.
[0058]
Further, the displacement correction sheet 73a may have a brush (brush) shape instead of a sheet shape.
[0059]
Such a displacement correction mechanism can correct the displacement of the bill without being influenced by the rigidity of the bill.
[0060]
Next, a displacement correcting mechanism that is particularly effective for banknotes having relatively high rigidity will be described.
[0061]
As shown in FIG. 10, this displacement correction mechanism includes a displacement correction guide 74 having inclined surfaces that gradually narrow the width of the conveyance path at both ends of the separation / stack guide 85.
[0062]
During the storing operation, the banknote is taken in the direction of the arrow along the separation / stack guide 85 by the conveying force of the stack / feed roller 81 and the gate roller 83 as shown in FIG. At that time, as shown in (b) and (c), the deviated banknote is taken into the stack space 96 while being elastically deformed by the deviating correction guide 74. Thus, at the moment when the banknotes conveyed into the stack space 96 while being elastically deformed are released from the clamping force of the stack feed roller 81 and the gate roller 83, the banknotes are restored to (d) by the restoring force from the elastic deformation. As shown, the stack is moved while moving in the center direction (in the direction of the arrow) of the stack space 96 and correcting the displacement.
[0063]
By implementing this displacement correction mechanism in combination with the displacement correction mechanism described above, more reliable displacement correction can be realized.
[0064]
In addition, as shown in FIG. 1, by arranging a top plate 94 on the top of the stack space 96, skew can be corrected when banknotes are taken into the stack space 96.
[0065]
As described above, the displacement correction mechanism applied to the horizontal recycle store 9 that stores banknotes in a standing posture has been described. However, it can also be applied to a vertical recycle store that stores banknotes in a horizontal posture.
[0066]
Moreover, although the embodiment of the deviation correcting mechanism described above corrects the deviation when the banknote is stored in a certain space, an area is provided in which the banknote is not sandwiched in the middle of the conveyance path. It is also possible to correct the deviation of the banknote in the middle of the transport path by installing the above-described deviation correction mechanism at the position.
[0067]
As described above, the banknote handling apparatus that handles banknotes has been described as an embodiment, but it can also be widely applied to apparatuses that handle slips, gift certificates, letters, and the like.
[0068]
【The invention's effect】
The present invention can correct a deviation of a paper sheet having low rigidity or a paper sheet having a large deviation without reducing the conveying speed with a simple structure. It is possible to prevent the paper sheet from staying and to stabilize the operation of the entire paper sheet handling apparatus.
