[Detailed Description of the Invention] [Summary] The present invention relates to an impeller mechanism in which the impeller can be easily removed from the rotating shaft.The purpose of this invention is to provide an impeller mechanism in which the impeller can be easily replaced. , consisting of a presser ring and a fixing ring,
The rotation shaft is provided in the conveyance path or above the paper sheets on the tray plate 1, parallel to the direction perpendicular to the transport direction of the paper sheets, and is rotated in the transport direction by a driving means. It is made of a flexible and elastic resin material, has a shaft hole that slidably fits into the rotating shaft, and has a predetermined length radially arranged at equal angles around the boss with slots in the width direction. A plurality of blade plates are provided on the rotary shaft, and the boss is fitted at a predetermined position on the rotary shaft by widening the slots, and the retaining ring is slidably fitted on the rotary shaft and The impeller has a large outer diameter and has at least one engagement protrusion on the side facing the plurality of blade plates of the impeller that engages the blade plate in the rotational direction near the base of the blade plate, and is fitted to the rotating shaft. It is fixed to the rotating shaft by engaging the engagement protrusion with the vane plate in contact with one side of the boss of the impeller, and the fixing ring is slidably fitted to the rotating shaft, and It is fixed to the rotating shaft by touching the opposite side of the boss of the impeller fitted to the retaining ring, and the impeller is rotated by the rotation of the rotating shaft, and the impeller is rotated by the blade plate. It is configured to transport paper sheets by hitting them.

(Industrial Application Field) The present invention relates to an impeller mechanism in a conveyance path of a paper sheet handling device, and more particularly to an impeller a structure that allows the impeller to be easily removed from the rotating shaft.

In recent years, automatic deposit and payment machines (Auto
oa+atic Teller Machine:
Automated transaction devices such as ATMs are widely used, and these devices have a built-in banknote handling device that transports, stores, and dispenses banknotes to be deposited and withdrawn.

In a banknote handling device, when skew occurs during conveyance of banknotes, the banknote is accelerated and hits the front roller to correct the skew, thereby accelerating the banknote to be stored in the storage section to facilitate storage. An impeller is used in this acceleration mechanism. By the way, the impeller is made of urethane rubber.
It is prone to wear and breakage due to use, so it needs to be replaced frequently.
Since the replacement work of removing and replacing the rotating shaft to which the impeller is attached requires a lot of man-hours, a mechanism that can easily replace the impeller is desired.

[Conventional technology]

FIG. 4 is an internal side view showing an outline of the banknote handling device 2 incorporated in the ATV. In the figure, to the right of the deposit and withdrawal port 3,
A dispensing section 41 that dispenses the inserted banknotes 1a one by one; a discriminating section 5 that distinguishes and counts the authenticity, denomination, and front and back of the banknotes 1a; and a front-back reversing section 6 that aligns the front and back sides of the banknotes 1a that have been turned upside down. Pool section 7. and a feeding section 8 are arranged. Further, a return/withdrawal pool section 9 is provided below the deposit/withdrawal port 3.

At the bottom of the device, banknotes 1a are sorted by denomination (1000 yen, 500 yen
0 yen.

Storage boxes 10a to 10c for storing 10,000 yen bills, respectively, are arranged, and storage rollers R1 to R3 for storing banknotes 1a and feeding rollers R4 to R6 for feeding them are provided above the storage boxes 10a=10c.

A reject part 11a is provided at the rear of the device, and a storage box 10 is provided.
It is collected when the banknote 1a fed out from a=LOc becomes unidentified due to double feed or the like.

In addition, a conveyance loop) A-M is provided between each mechanism, and a feed roller 1 (not shown) is provided at a necessary location, and a feed belt (not shown) is provided.
Gates G1 to G8 are provided at the branch points. Each of the above sections is controlled by a control section (not shown).

Therefore, the banknotes 1a inserted into the deposit/withdrawal slot 3 at the time of deposit are discriminated and counted in the discrimination section 5, and are aligned front and back in the front and back alignment section 6 and pooled in the pool section 7. Once the amount is confirmed, the bills 1a are again dispensed into the dispensing section 8. They are unrolled, the denomination is identified, and each is placed in a storage box 1.
It is stored in 0a”lOc.

After being sent to the return/withdrawal pool section 9, the failed banknotes are returned through the deposit/withdrawal port 3.

In addition, when withdrawing money, banknotes 1a are fed out from the storage box 10a''lOc, verified by the verification section 5, the amount is counted, pooled in the return/withdrawal pool section 9, and then paid out to the deposit/withdrawal port 3.

Here, the money 1a conveyed along the conveyance route A-M travels diagonally during conveyance, so as shown in FIG. ,
14b (details will be described later) to accelerate the banknote 1a (b
At this point, as shown in Figure 5, the skew is corrected by colliding with the front ['J-ra Ri]. That is, the impeller mechanism 12
A is a rotating shaft 13a on the L side of the route along which the banknotes 1a are conveyed.
Multiple impellers! As shown in FIG. 6, the impellers 14a and 14b are made of a resin material 1 having flexibility and elasticity, such as urethane rubber. The rotating shaft 13
a has a shaft hole 17a that is slidably fitted into the boss 15a.
Feather plates 16a of a predetermined width radially arranged at equal angles on the outer periphery of the
16b, - are provided.

Also, a metal ring 18a of the same diameter is attached to one side of the boss 15a.
, 18b are glued together, and metal rings 18a, 18b are fixed to the rotating shaft 13a with screws.

The lengths of the vanes 16a, 16b, are shown in Figure 5 (al
As described above, by rotating the rotary shaft 13a in the transport direction, it is set to rub the transport route surface while bending. Further, the rotating shaft 13a is rotated by a seven-wheel drive, and its rotational speed is set to a speed that accelerates the conveyance speed of the banknotes 1a.

Therefore, the banknotes 1a are accelerated by being hit by the impellers 14a and 14b, and are conveyed while their skew is corrected.

Also, when storing banknotes 1a in storage boxes 10a to 10c,
As shown in the seventh drawing, the banknotes 1a are accelerated by the impeller mechanism 12b, and the banknotes 1a collide with the side walls of the storage boxes 10a to 10c to be stored.

That is, the impeller mechanism 12b is a mechanism similar to the impeller mechanism 12a described above, and is located on the right-L in the diagram of the storage boxes 10a to 10c.
It is provided outside the storage opening 19 at the end.

Therefore, the number of stored banknotes 1a is 8! When the banknotes 1a are sawed, they are hit by the blades 16a, 16b, . . . and are accelerated and stored.

In addition, as a different conventional example, as shown in FIG. 8, an impeller mechanism 12c is a mechanism similar to the impeller mechanism 12a described above, and when a device such as a printer sends out a plurality of sheets of paper 1b to a stacker 30, a plurality of sheets of paper 1b are It is used when stacking papers with their leading edges aligned one after another, and by rotating in the direction of the arrow, the paper 1b moves in the direction of the abutment 31 and the leading edges are aligned.

Impellers 14a and 14b of the impeller mechanism t2a=12c
Since the blade plates 16a, 16b, are constantly bent and rubbed by the conveyance route and the banknotes 1a, they are easily worn out or broken, and need to be replaced. The shaft 13a and the impellers 14a and 14b are replaced together with the shaft 13a.

[Problems to be Solved by the Invention] According to the above-mentioned conventional method, when the impeller of the impeller mechanism is replaced in the event of a broken IM, the entire rotating shaft is disassembled and removed from the device, and disassembling and removing the rotating shaft is extremely troublesome.
