BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper sheet transport mechanism for transporting paper sheets such as banknotes by sandwiching the same with a transport belt.

[0002]

2. Description of the Related Art Heretofore, a transport mechanism for transporting paper sheets while sandwiching the same with a transport belt has been used for financial instruments and the like installed in financial institutions. FIG. 4 is a schematic side sectional view showing a bill automatic payment device installed in a financial institution. In the figure,
A dispensing port 2 is provided on the front of the device housing 1, a rear door 3 is provided on the back side, and a payment mechanism 4 is provided inside the housing 1.

[0003] The following components are provided in the payment mechanism 4. That is, a shutter 5 provided at the dispensing port 2 so as to be openable and closable, a stage 6 disposed near the shutter 5 for temporarily accumulating and storing bills to be paid, an accumulating roller 7 disposed at one end of the stage 6, Safe 8, which stores gold bills
9. Delivery means 10 and 11 for delivering bills in safes 8 and 9.
Transport paths 12a, 12b, 1 through which the fed bills are transported
2c, 12d, a reject safe 13 disposed immediately below the stage 6, a sensor 14 for detecting a full state of banknotes in the reject safe 13, a lower transport belt 15 disposed below the stage 6, and an upper part of the lower transport belt 16 Are provided respectively.

Next, the payment operation will be described. When the customer inserts a card from a card insertion slot (not shown) and presses a key on the operation unit to input information such as a personal identification number and a required payment amount, the banknotes 1 and 9 are fed from the safes 8 and 9 by the feeding means 10 and 11. The bills are fed one by one, and the fed bills are conveyed by the conveying paths 12a to 12d and are stacked on the stage 6 by the stacking rollers 7.

[0005] When the amount and number of bills requested by the customer are accumulated on the stage 6, the bills are clamped by the upper transport belt 16 and the lower transport belt 15. The upper transport belt 16 is configured to rotate in the direction of arrow A. With this rotation, the stacked banknotes are nipped by the upper transport belt 16 and the lower transport belt 15, and the two transport belts 15,

Transported to Thereafter, the shutter 5 is opened, and the customer can take out the banknote from the outlet 2.

[0006] If the customer does not take out the bill even if the shutter 5 is opened, that is, if the customer forgets to take the bill, the shutter 5 is closed after a certain period of time, and the bill is dropped into the reject safe 13. You.

[0007]

However, in the above-described conventional apparatus, when the number of bills to be paid increases, the bills sandwiched between the upper and lower conveyor belts become thicker as shown in FIG. 16 bends. The transport belt 15 is hardly bent because it is a toothed belt. In this state, when the transport belts 15 and 16 are driven to transport the bills 17, as shown in FIG. 6, the bills 17 are inserted between the pulley 18 a that drives the transport belt 16 and the transport belt 16, and the bills 17 are transported. In some cases, it could not be transported. FIGS. 5 and 6 are explanatory views showing a state of transporting bills in a conventional example.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to prevent the conveyance belt from being bent even if the number of paper sheets to be sandwiched is large, thereby preventing the paper sheets from being stuck. It is another object of the present invention to provide an excellent transport mechanism for satisfactorily transporting paper sheets.

[0009]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to a paper sheet transport mechanism for sandwiching and transporting stacked paper sheets by two transport belts stretched over pulleys. The two transport belts are each composed of a flat belt and a toothed belt, are disposed separately inside the transport belt composed of the flat belt, extend near the downstream pulley in the transport direction of the paper sheets, and extend from the flat belt. A transport guide having a guide surface for restricting the transport belt in a planar direction is provided.

[0010] Further, in a sheet transport mechanism for sandwiching and transporting stacked paper sheets by two transport belts stretched over pulleys, the two transport belts each comprise a flat belt and a toothed belt. A guide surface is disposed inside the flat belt and spaced apart from the pulley on the downstream side in the transport direction of the paper sheet, and forms a guide surface that regulates the surface belt of the flat belt. And a rotatable roller disposed at an intermediate portion of the conveyance guide and protruding toward the conveyance belt from the guide surface.

[0011]

According to the present invention having the above construction, the transport guide is provided between the vicinity of the pulley on the downstream side in the transport direction of the paper sheet and the position facing the sandwiched paper sheet. When holding the sheets, the transport belt does not bend even if the number of sheets is large. Since the conveyance guide is provided to the vicinity of the pulley on the downstream side in the conveyance direction, even if the conveyance belt holding the sheets is driven, the conveyance belt conveys the sheets without bending. There is no difficulty between the conveyor belt. Further, by providing the rollers, it is possible to prevent abrasion of the transport belt caused by the contact of the transport belt with the transport rollers.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment according to the present invention will be described below with reference to the drawings. Elements common to the drawings are assigned the same reference numerals. FIG. 1 is an explanatory view showing a transport mechanism of an embodiment according to the present invention, and FIG. 2 is an explanatory view showing a transport mechanism of an embodiment in which bills are held. The transport mechanism described in the present embodiment is mounted in a bill automatic payment device as in the case of the conventional example.

In FIG. 1, the conveyor belt 15 has a pulley 2
0a and 20b, and is driven by the pulley 20a being rotationally driven by a motor (not shown). The transport belt 15 is a toothed belt. The transport belt 16 is stretched around pulleys 21a and 21b.
The pulleys 21a and 21b are rotatably supported by a bracket 22, and the pulley 21a is driven to rotate by a motor (not shown). The bracket 22 is rotatable in the direction of arrow A about the axis of the pulley 21a.

A transport guide 23 is fixed to the bracket 22, and the transport guide 23 forms a guide surface 23 a facing the inner side of the transport belt 16.
The guide surface 23a is provided up to the vicinity of the pulley 21a, and is also formed at a position facing the banknote 24 when the banknote 24 is held between the transport belts 15, 16 as shown in FIG.

A projection 25 is formed on the bracket 22 between the two guide surfaces 23a, and a roller 26 is rotatably provided on the projection 25. Roller 26
Is substantially in contact with the inside of the conveyor belt 16, that is,
The transport guide 23 is disposed closer to the transport belt 16 than the guide surface 23a.

By rotating the conveyor belt 16 in the direction of arrow A shown in FIG. 1, the stacked banknotes 24 are held between the conveyor belt 16 and the conveyor belt 15. At this time, the transport belt 16
Is bent by being pushed by the stacked banknotes 24, but contacts the guide surface 23a as shown in FIG. In this state, the transport belt 15 and the transport belt 1
When the motor 6 is driven by a motor (not shown), the pinched banknote 24 is transported in the direction of arrow B. The conveyor belt 16 is driven to rotate by being guided by the guide surface 23a and the rollers 26.

Even if the leading end of the bill 24 reaches the vicinity of the pulley 21a, the transport belt 16 keeps the guide surface 2 of the transport guide 23.
It contacts the roller 3a and the roller 26 and does not bend so much. Therefore, the bill 24 does not get into the gap between the transport belt 16 and the pulley 21a, and the transport of the bill 24 is performed without any trouble.

Since the roller 26 protrudes toward the conveyor belt 16 from the guide surface 23a, the roller
Is not in surface contact with the guide surface 23a, and therefore, the wear of the transport belt 16 during driving is small. Further, since the transport guide 23 in the present embodiment is provided substantially within the area where the transport belt 16 is provided, the mounting space may be narrow, which is suitable for a case where the transport guide 23 is incorporated in a device having a high component mounting density.

[0019]

As described above in detail, according to the present invention, since the transport guide is disposed inside the transport belt, the transport belt does not flex or slightly flexes even when the stacked banknotes are pinched. Since there is no bill, the bill is conveyed normally without being jammed between the belt and the pulley.
