Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper sheet accumulating apparatus and a paper sheet processing apparatus for accumulating and binding paper sheets such as securities.

[0002]

2. Description of the Related Art A paper sheet processing apparatus of this type includes a supply unit for stacking a large number of securities, a take-out device for taking out the securities one by one from the supply unit, and a valuable device taken out by the take-out device. A transport device that transports securities along a predetermined transport path, an inspection unit that inspects the papers transported by the transport device, and a sorting unit that separates the transport direction according to the inspection result of the inspection unit. And a binding device for stacking, for example, 100 securities each having a transport direction divided by the sorting portion and binding them in a small band, and a predetermined number of bundles bound by the binding device, for example, 10 bundles of large bundles. And a large band binding device that binds together.

[0003] The above-mentioned binding device has an accumulating device for accumulating securities and a binding device for binding the securities accumulated in this accumulating device. The accumulator has an impeller,
Securities are introduced into the impeller and conveyed. When the securities reach a predetermined position, the leading end thereof is brought into contact with a scraping plate, scraped out of the impeller, and dropped and accumulated in an accumulation portion.

[0004] The impeller has connectivity with a transport device for transporting securities, a smooth introduction of the securities, a length capable of completely storing the securities, and a sufficient speed reduction of the securities. In many cases, the blade body is shaped to follow the involute curve.

However, if the impeller blade body is simply shaped along the involute curve, a sufficient deceleration effect cannot be obtained due to the influence of the material of the securities and a change in the friction coefficient of the blade body with time. Sometimes.

In this case, there is a relative speed between the securities and the impeller, and the leading end of the securities is strongly contacted with the scraping plate and rebounds, and the leading ends of the securities are gathered together. It becomes difficult to carry out the binding, and the binding condition becomes poor.

Therefore, conventionally, a disc-shaped brake is coaxially mounted on the center axis of the impeller, and the tip end of the securities inserted into the blade groove is sandwiched between the brake and the blade body to reduce the speed. I was trying to get an effect.

[0008]

However, the conventional brake has a great effect on deceleration of securities,
Since all of the momentum of the securities is received by being sandwiched between the blade body and the stopper, a large shear force is generated at the two leading ends of the securities, which may cause a crack.

The present invention has been made in view of the above circumstances,
Paper sheets inserted into the blade groove of the impeller without causing any shearing force at the tip of the paper sheet, and reliably reducing the speed to zero the relative speed between the paper sheet and the impeller An object of the present invention is to provide a stacking device and a sheet processing device.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to an embodiment shown in the drawings. FIG. 1 shows a securities processing apparatus 10 as a paper sheet processing apparatus. The securities processing device 10 takes out and inspects and counts the securities as paper sheets one by one, and accumulates a fixed number of sheets, for example, every 100 sheets, and binds them by a small band to form a binding bundle.

At the right end of the processing apparatus, 1000 pieces of securities are collectively stacked in a stacked state. An input device 12 is provided as a supply means for automatically inputting the liquid sequentially.

Securities whose length has been detected are classified into a plurality of types according to the detection result, for example, a clean ticket, a heavily soiled ticket, and a discarded ticket, and the binding unit 24 or the expired unit 2 for each type.
Sent to 3.

The binding unit 24 includes two units corresponding to the type of securities.
It has two binding devices 24a, 24b. These binding devices 24a and 24b have an accumulating device 1 for accumulating securities to be bound. Bundling device 24a,
Below the bunch 24b, there is provided a bundle transport device 22 for transporting the bound bundles. A bundle bundle formed by binding 100 securities is conveyed to the large bundle unit 21 by this bundle conveying device 22, where a predetermined number of bundles, for example, 10 bundles, are bundled.
The bundle is bound by a large band and then discharged to a predetermined portion by the discharge device 15.

The large bundle bundling device 21 includes a bundling portion 25 provided below the small bundle conveying device 22 as a supplied portion, and a band supply device 26 that supplies a large band to the bundling portion.
2 and 3 show the integration device 1 of the binding unit 24 and the driving device 6 thereof.

The stacking device 1 introduces the securities P conveyed by the traveling of the conveyor belt 2 and sends the securities P in a predetermined direction, and the securities P sent by the impeller 3 from the impeller 3. A scraping plate 4 for scraping and discharging,
A stacking unit 5 is provided below the impeller 3 and accumulates securities P discharged from the impeller 3. Impeller 3
As shown in FIG. 3, are mounted on one end of the drive shaft 7 in parallel at a predetermined interval. Drive shaft 7
Is rotatably mounted on a support frame 8 via a mounting 9. The drive shaft 7 is connected to a shaft 35 of a drive motor 34 via a pulley 26, a drive belt 27, and a drive pulley 28 in the middle. The drive motor 34 is mounted on the support frame 8.

When the drive motor 34 rotates, the drive belt 27 travels, and the travel causes the impellers 3, 3 to rotate via the drive shaft 7. As shown in FIG. 4, the impeller 3 includes a circular rotor 31 and a plurality of blades integrally formed at a predetermined interval on the outer peripheral portion of the rotor 31 in the rotation direction. 32 ... The plurality of blades 32 are formed into a shape curved along an involute curve, and blade grooves 32a for introducing securities P are formed between the blades 32.

The blades 32 of the impeller 3 protrude from the roots of the blades 32 in the direction of curvature of the blades 32, and have a high frictional resistance against the securities P inserted into the blade grooves 32a. A projecting portion 37 for applying is integrally formed.

Next, the operation of accumulating securities P will be described. As the transport belt 2 runs, the transported securities P are inserted into the blade grooves 32a of the rotating impeller 3. Immediately after entering into the blade groove 32a, the security P inserted into the blade groove 32a has its tip abutting on the inner surface of the blade body 32 to cause momentary buckling. Proceed along. The traveling securities P receive a dynamic frictional force from the inner surface of the blade groove 32a while having a relative speed with respect to the impeller 3. By continuously receiving the dynamic friction force, the securities P have a zero relative speed with respect to the impeller 3, and are conveyed integrally with the impeller 3. Thereafter, the security P is scraped off when its tip collides with the scraping plate 4 with the relative speed being zero. Then, the scraped-out securities fall freely and are accumulated on the accumulation section 5.

By the way, the blade groove 32a of this securities P
If the relative speed with respect to the impeller 3 does not become zero at the time of the insertion, the impact of the securities P on the scraping plate 4 becomes large and the securities P are strongly rebounded. If it is bounced strongly in this manner, the leading end of the securities P is disturbed, the accumulation state is disturbed, and the binding state is deteriorated.

The fact that the blade groove 32a has a shape following the involute curve is excellent in that the securities P can be smoothly introduced to impart a kinetic friction force, but that the relative speed with respect to the impeller 3 is reduced to zero. Is not enough, and the above-mentioned problem occurs.

Therefore, in this embodiment, as described above, the arc-shaped protrusion 37 protruding in the curved direction is integrally formed at the base of the blade body 32a shaped along the involute curve.

When the securities P conveyed along the blade grooves 32a reach the protruding portion 37, they come into sliding contact with the protruding portion 37 and a large frictional force is applied, so that a high deceleration effect can be obtained. As a result, the relative speed of the securities P with respect to the impeller 3 becomes zero, and the securities P are not scraped off in a state in which the tips are disturbed, and a good accumulation state with little variation in the tips is obtained. .

When the radius of the involute base circle is Ra and the radius of the protruding portion 37 of the blade 32 is Rb, Ra × R
It is desirable to have a relationship of 1.5 ≦ Rb ≦ Ra × 2.5. That is, if the radius of the protruding portion 37 of the blade 32 is 1.5 times or less the radius of the involute base circle, the protruding portion 37 is too rearward of the blade 32 and the deceleration effect is too slow. If the ratio is more than .5 times, the deceleration by the protruding portion 37 starts from an early stage, so that the securities P are easily buckled.

In this embodiment, the radius of the protrusion 37 is 35 mm with respect to the base radius of the involute of 20 mm. FIG. 5 shows another embodiment of the present invention.

In this embodiment, the impeller 3 is provided with a stopper 41 as a speed reducing means. Stopper 4
Reference numeral 1 denotes a disk portion 42 which is mounted coaxially with the impeller 3 on the outer side of the impeller 3 and which is rotatably provided on the outer peripheral portion of the disk portion 42 at a predetermined interval in the rotation direction. The protrusions 43 are fitted into the blade groove 32a in a nested manner at the base side in the blade groove 32a.

A part (hereinafter referred to as an inclined piece 43a) of each of the projections 43 ... fitted into the blade groove 32a is inclined so as to form a wedge with the opposing blade body 32. The securities P inserted into the blade grooves 32a of the impeller 3 are stopped by the frictional force applied thereto while the leading ends thereof slide and deform along the inclined pieces 43a of the stopper 41. Therefore, as before,
The relative speed of the securities P with respect to the impeller 3 can be reduced to zero without generating a shearing force at the tip of the securities.

[0040]

As described above, according to the present invention, a plurality of blades are integrally formed with a protruding portion protruding in an arc shape in the curved direction at the base side, and the protruding portions are used for the paper sheet. Since frictional force is applied, it is possible to apply higher frictional force to paper sheets compared to a conventional blade body that only follows the involute curve, and the relative speed of the paper sheets to the impeller is zero. Can be

Therefore, the relative speed with respect to the impeller can be reduced to zero without generating a shearing force at the leading end of the paper sheet as in the related art, and the leading end of the paper sheet is not damaged. .

The frictional force is imparted by slidingly deforming the leading end of the paper sheet inserted into the blade groove, which is inserted into the blade groove formed between the blade bodies, thereby reducing the speed. Since there is a deceleration means for reducing the speed of the paper leaf, the relative speed with respect to the impeller can be reduced to zero without generating a shearing force at the front end of the paper leaf as in the related art. There is no.
