2 shows a second stage in which the wafer is further transported.

As shown in these figures, in a state where the trailing end of the bill P has passed between the carrying roller 9 and the carrying roller 24, the bill P receives the weight of the pressing member 42 near its leading end. P is concave rollers 44 and 45 and pressing roller 5
The bent shape given by the guide members 5 and
3 and 54, and the banknote P
Is supported between the concave rollers 44 and 45, the pressing rollers 50 and 51, and the guide member with respect to the transport direction, so that rotation of the banknote P in the clockwise direction in the figure is suppressed. Thereby, since the front end of the bill P does not bend, the bill P reaches the carry-in / out port above the storage portion without being collided with the bill Ps carried in earlier, while keeping the carrying posture stable.

As described above, the concave rollers 44 and 45, the pressing rollers 50 and 51, and the guide members 63 and 54 cause the bill being conveyed to bend in the width direction so that the bill has a strong waist (rigidity) in the conveying direction. This constitutes means for giving.

Until the trailing end of the banknote P reaches the position of the impellers 13 and 18, the blades 13a and 18a of the impeller rotate while entering the lower surface of the banknote P while being deformed. It is not hit by a car,
When the trailing end of the bill P passes through the positions of the impellers 13 and 18 as shown in FIG. 4, the trailing end of the bill P is moved to the blades 13a and 1a of the impellers 13 and 18 so as not to hinder the subsequently carried bills.
By 8a, the banknotes are beaten downward from above and stacked on the banknotes Ps (the stage 3 when there is no banknote) carried in earlier.

Next, the operation of unloading a bill will be described.

When the banknote P in the storage section 2 is carried out from here, the solenoid 57 is urged and the plunger 58 is sucked. As a result, the plunger 58 pulls the connecting plate 56 rightward in the drawing, and as shown in FIGS.
47 is the rotating shaft 2 against the urging force of the coil spring 52.
6 is rotated clockwise in the figure. As a result,
Press rollers 50, 5 attached to arms 46, 47
1 and the guide members 53 and 54 are raised upward and retracted out of the transport path 1.

Pressing rollers 50 and 51 and guide member 5
2 and 3 are retracted from the transport path 1 so that
As shown in FIG. 8, there is no resistance in the transport path 1 when the banknote P is transported.

Next, the stage 3 is moved by the elevating motor (not shown) so that the banknotes P
And raise it. As a result, the upper surface of the uppermost banknote P is brought into contact with the transport rollers 27 and 29. Here, by rotating the transport rollers 27 and 29 in the clockwise direction in the figure, the uppermost banknote P is fed out from the storage section 2 toward the transport path 1, and further, the transport roller 21 and the gate roller 17.
Then, the sheet is carried out to the outside via the conveyance path 1 between the conveyance roller 24 and the conveyance roller 9.

[0028]

However, in such a conventional paper sheet storage device, the rear end of the paper money P loaded into the storage unit 2 at the time of the paper currency transfer operation is the impeller 13,
After passing through the position 18, since the bent shape maintained by the guide members 53 and 54 is eliminated, the strong waist (rigidity) given to the banknote P disappears. Also, as shown in FIG. 51, when the front end of the bill P is pushed upward by the pressing member 42 and the trailing end of the bill P is knocked down by the blades 13a and 18a of the impeller, the bill P is moved in the transport direction. Since the strong waist has disappeared, the bill may be bent to both sides with its central portion as the vertex and deformed into a convex shape. In this state, when the next bill is carried in, jamming easily occurs in the bill,
Further, the banknotes cannot be stacked on the stage 3 of the storage unit in a flat and normal state. If the banknotes conveyed into the storage unit cannot be stacked flatly, the banknotes may jam in the middle of the conveyance when the banknotes are conveyed out of the storage unit, and may be jammed in the conveyance path 1 and may not be conveyed.

According to the present invention, in order to solve such inconveniences, a paper sheet storage device capable of smoothly loading and unloading banknotes without causing jamming of the banknotes when loading and unloading the banknotes into and out of the storage device.

However, if the supporting portion of the bending assist member becomes longer, the posture of the banknote becomes stable, but it becomes a resistance when the banknote is dropped. Therefore, the length of the supporting portion is preferably determined by a combination of both.

Next, a description will be given of the operation of loading the banknotes of the paper sheet storage device of the embodiment of the present invention thus configured.

FIGS. 6 to 8 show the first stage of the process of loading a bill. The bills P, which are sandwiched between the upper and lower transport rollers 6, 6 and 24, 24 and are transported from the left entrance of the transport path 1 in the direction of the right storage section 2, are pressed by the concave rollers 44, 45 and the pressing rollers 50, 51. When passing between the concave roller 4
The banknotes P are bent in the width direction by the convex portions at both ends of the outer peripheral surfaces of the banknotes 4 and 45. At this time, the bill P is

A strong waist (rigidity) is provided in the transport direction of the banknote P, and the banknote P extends straight without being bent in the transport direction.

When the banknote P further moves toward the storage section 2,
Guide members 53 and 54 whose both ends in the width direction of the bill are inclined.
Are further scooped up by the inner wall surfaces 53a, 54a of the bill, and the bill is in a state in which the cross section is bent substantially in a U-shape,
It is supported in the same posture and enters above the storage section 2.

The banknote P further advances, and the bending assist member 103 whose leading end protrudes into the transport passage above the storage section 2.
In the state of the second stage as shown in FIGS. 9 to 11 in which the sheet P has passed through the position 104 and the rear end has passed between the conveying rollers 6, 6 and 24, 24, the bill P Although receiving the weight of the pressing member 42, the banknote P is sandwiched between the concave rollers 44 and 45 and the pressing rollers 50 and 51, is supported by the guide members 53 and 54, and has an interval smaller than the width of the banknote P. Bending assist member 103, 1
04 supports both ends of the banknote P in the width direction, the U-shaped bending posture of the banknote P is maintained as it is, and the banknote P
Is prevented from rotating clockwise in the figure. Accordingly, the leading end of the bill P can be kept at a position above the extension line extending the transport path 1 horizontally until immediately before the leading end of the bill P reaches the rear wall portion 41 of the storage unit 2.
Arrives at the upper part of the storage part 2 without colliding with the banknote Ps previously carried into the storage part 2 and in a stable transport posture.

The bending assist members 103 and 104 project from both sides in the width direction into the transport path above the storage section 2 to narrow the width of the transport path, but the leading end of the bill P passes therethrough. At this time, since the bill P is bent in a U-shape while being picked up by the guide members 53 and 54 when passing through the guide members 53 and 54, the tip of the bill P is slantingly upward in a state where the width of the tip is reduced as a whole. Since the banknote P is carried in while being turned, the front end of the banknote P
Even if the banknote P is carried in a state where the bill P is lowered to a position at which the banknote 04 is provided, the carrying of the banknote P is not performed by the bending assisting member 1013,
The operation is smoothly performed without being hindered by 104.

When the bill P is further conveyed, the bills P shown in FIGS.
This is the third stage as shown in FIG.

At this stage, when the trailing end of the bill P has passed through the positions of the impellers 13 and 18, the trailing end of the bill P is controlled by the blades of the impeller so as not to hinder the subsequently carried bills. It is knocked down. As a result, the rear end of the bill P is no longer supported, so that the leading end of the bill P is rotated clockwise in the figure by the weight of the pressing member 42 which has been lifted by the bill itself, and the bill P is moved into the storage unit 2. Be dropped. At this time, the bending assist member 103, 104 changes the bent shape of the banknote P given by the guide members 53, 54, etc.
Can be maintained even after passing through the guide members 53 and 54, so that a strong waist is maintained near the center of the banknote P provided with the bending assist member. As a result, the banknote P can be dropped into the storage section 2 in a substantially horizontal and stable posture while maintaining the banknote P in a bent state having a U-shaped cross section.

As described above, in the apparatus of the present invention, the bill P
When the paper money P is dropped into the storage section 2 from above, the front and rear end sides of the paper money P are not bent downward around the central portion thereof, so that the paper money P is not deformed in a convex shape. As shown in FIG. 14 (fourth stage), when the banknotes are loaded on the previously loaded banknotes Ps (stage 3 if there are no banknotes), the banknotes are aligned in a horizontally extended state without jamming. Stacked.

Next, the unloading operation when the banknotes stored in the storage section 2 are unloaded to the transport path 1 will be described.

As shown in FIGS. 15 and 16, when a bill is carried out, the solenoid 57 of the retraction mechanism is urged and the plunger 58 is sucked to set the carry-out mode. As a result, the upper ends of the arms 46 and 47 are rotated clockwise in the drawing against the coil spring 52 via the connecting plate 56, and the pressing rollers 50 and 51 and the guide members 53 and 54 at the lower ends of the arms are conveyed. It is evacuated above Road 1.

When the stage 3 on which the banknotes are stacked is raised by a lifting motor (not shown), the stage 3 and the banknotes P are raised with the holding member 42 placed thereon. Due to this rise, the bending assist members 103 and 104 are provided at intervals smaller than the width of the bill and slidably in the vertical direction.
The uppermost banknote comes in contact with the banknote and the spring 103
The uppermost banknote abuts against the outer peripheral surfaces of the transport rollers 27 and 29.
Thereafter, the transport rollers 29, 27, 2
1 and 24 are synchronously rotated clockwise in the opposite direction to the time of loading, so that the banknotes stacked in the storage unit 2 can be moved one by one from the top to the outer circumference of the friction members 29a and 27a of the transport rollers 29 and 27. Can be fed out to the transport path 1 side. The bills fed into the transport path 1 are respectively separated by the gate roller 17 and the transport roller 21 and the transport roller 2
The sheet is conveyed to the left side entrance side of the conveyance path 1 between the sheets 4 and 9.

As described above, the bending assisting members 101 and 102 provided on the transport path above the storage section 2 to assist the bending of the bills become resistors which bend the bills during the loading operation of the bills. During the unloading operation, the banknotes are automatically retracted from the transport path, and do not affect the unloading of the bills.

In the above embodiment, as the mechanism for retracting the bending assist member, a mechanism in which the bending assist member is slidably supported in a vertical direction and biased downward by a spring has been described. The present invention is not limited to this. The bending member retracting mechanism projects the bending auxiliary member into the transport path during the operation of loading the banknote, and retracts the bending auxiliary member to the outside of the transport path during the unloading operation. It is also possible to use a mechanism that is displaced in the horizontal or horizontal direction so as to protrude and retract into the transport path.
