Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a banknote sorting device that stacks and aligns banknotes fed one by one so that they are shifted little by little along the conveyance direction.

BACKGROUND ART In a banknote-based automatic vending machine, automatic ticket vending machine, etc., when a user presses a cancel button after inserting multiple banknotes into the machine, when the banknotes are returned to the user, the banknotes to be returned are are aligned in the confirmation window with their tips slightly shifted one on top of the other so that the user can easily confirm the amount of the banknotes, that is, the type and number of bills, through the confirmation window before receiving the banknotes, It is desirable to be able to prevent troubles regarding the amount to be returned.

In addition, in order to prevent problems with the payout amount at automatic currency exchange machines that exchange high-value banknotes for low-value banknotes, automatic cash dispensing machines for deposits, etc.,
It is desirable that the bills to be dispensed be arranged in a stacked manner with their tips offset from each other in the confirmation window so that the user can easily confirm the type and number of bills from the confirmation window before receiving the bills. ing.

As this type of device, a banknote aligning device disclosed in Japanese Patent Application Laid-open No. 130698/1983 is known. This banknote sorting device is equipped with a pair of endless belts that are installed downstream of the validating machine and transports the banknotes while holding the front end of the banknotes between them.The device disconnects power from the first solenoid mechanism of the upper endless belt on the validating machine side. At the same time, the arm having a space through which the banknotes sent from the validating machine passes is moved up to the front stage of both endless belts by energizing the second solenoid mechanism to separate the banknotes from the lower endless belt. Curve the end upwards. In this state, when the next banknote is fed from the discriminator, the next banknote overlaps below the banknotes already stored in both endless belts. After that, when the first solenoid mechanism is energized, the upper endless belt and the lower endless belt clamp the banknote, and when the second solenoid mechanism is de-energized, the arms descend, and then both endless belts slightly transport the banknotes. By doing this, the banknotes that are fed one by one are stacked and arranged in a slightly shifted state.

Problems to be Solved by the Invention However, in the banknote sorting device described above, the upper endless belt moves toward the lower endless belt and clamps the banknotes. As a result, the holding position of the banknotes is tilted,
Therefore, there was a problem in that a plurality of banknotes could not be arranged in such a manner that their tips were regularly shifted from each other.

The present invention has been made in view of the above-mentioned problems, and provides a banknote aligning device that can reliably align a plurality of banknotes by superimposing them so that their tips are regularly shifted from each other using a simple mechanism. The purpose is to

Means for Solving the Problems According to the present invention, the above-mentioned problems are solved by a first conveyance mechanism that pinches and conveys fed banknotes by a pair of upper and lower endless belts arranged in parallel; a second conveyance mechanism that operates for a certain period of time each time a banknote is fed from the conveyance mechanism and clamps the front end side of the banknote; a drag mechanism that rotates in the same direction as the first conveyance mechanism around a shaft that supports a pulley on the downstream side around which the endless belt is wound; and a guide facing the first conveyance mechanism, the downstream end of the lower endless belt is further away from the second conveyance mechanism than the upper endless belt, and the drag mechanism includes: Located between the endless belts below the first conveyance mechanism, one side extends from the endless belt below the first conveyance mechanism toward the second conveyance mechanism along the banknote conveyance path by the first conveyance mechanism. The second conveyance mechanism is provided at the lower side of the banknote conveyance path, and when the second conveyance mechanism stops, it rotates once together with the first conveyance mechanism, so that the rear part of the banknote is curved downward along the guide. This problem can be solved by creating a banknote sorting device.

Function When a banknote is fed from the first conveyance mechanism with the picking mechanism stopped, the second conveyance mechanism operates for a certain period of time, pinches the leading end of the banknote and conveys it slightly, and then transfers the banknote slightly. After the second conveyance mechanism stops with the leading edge of the banknote clamped, the first conveyance mechanism continues to feed the trailing edge of the banknote, and the retrieval mechanism is centered around the shaft that supports the downstream pulley of the endless belt below. The banknote is rotated once in the same direction as the endless belt below to bend the rear part of the banknote downward along the guide. Then, with the retracting mechanism stopped, the first
When the next banknote is fed from the transport mechanism, the next banknote overlaps the top surface of the previous banknote that has already been held by the second transport mechanism, and when the second transport mechanism operates for a certain period of time in this state, The next banknote is clamped together with the previous banknote by the second conveyance mechanism in a state where the leading edge side is shifted by a certain amount from the front edge of the previous banknote that has already been clamped.

The endless belts 8a, 8b; 10a, 10b are rotated together with the banknote transport mechanism within the banknote processing apparatus 1. Therefore, the first rotation mechanism can be used in common with the rotation mechanism of the banknote transport mechanism in the banknote processing apparatus 1.

In this example, the second conveyance mechanism 4 is a pair of a drive roller 4a and a pinch roller 4b, and shafts 17a and 17b supporting each roller are connected to support walls 14 and 14.
It penetrates freely and rotates freely. The shaft 17a is a gear 18
It is connected to a third rotation mechanism (not shown) such as a motor via a motor, and is rotated for a certain period of time when the bill detector 7 detects the rear end of the bill. The banknote detector 7 is
It is separated from the second transport mechanism 4 toward the banknote processing apparatus 1 by approximately the same distance as the length of the banknote in the transport direction.

The drag mechanism 5 includes a lower endless belt 10a, 1
Lower endless belt 10 is positioned between 0b and 0b.
It is fixed to the shaft 13b that supports the pulley 11b on the downstream side around which the belts 5a and 10b are wound. The portion 5b hangs down in the normal direction of the banknote conveyance surface, and when the second conveyance mechanism 4 rotates and then stops, the gear 16 and the shaft 1
3b, the second rotating mechanism rotates the endless belts 10a, 10 in the clockwise direction (indicated by arrow A) in FIG.
It is rotated once in the same direction as b. The arcuate portion 5c of the retracting mechanism 5 has two holes adjacent to the side portion 5a and the side portion 5b.
Holes 19, 19 are formed at the locations, and each hole 1
Rollers 20, 20 are provided at portions 9, 19. The rollers 20, 20 are rotatably supported by columns 21, 21 having slits 22, 22 formed in the same direction as the shaft 13b, and are supported by torsion coil springs 24, one end of which is fixed to the locking pieces 23, 23. , 24 toward the outside of the arcuate portion 5c. The pillars 21, 21 are circular arc portions 5

The guide 6 is curved to have a radius slightly larger than the radius of curvature of the circular arc portion 5c of the retracting mechanism 5, and the curved portion is in the circular arc portion 5c in the standby state.
They are fixed to supporting walls 14, 14 so as to face each other along. The upper part of the guide 6 is an endless belt 10
It is bent toward the second transport mechanism 4 so as to coincide with the banknote transport surface formed by a and 10b.

When a banknote is fed from the banknote processing apparatus 1, this device uses endless belts 8a, 8b; 10a, 10b.
rotates in synchronization with the transport mechanism in the banknote processing apparatus 1, so the first transport mechanism 3 transports the banknotes toward the second transport mechanism 4. At this time, the pulling mechanism 5
In this case, the side portion 5a acts as a guide for the banknote.

When the rear end of the banknote passes below the banknote detector 7, the second conveyance mechanism 4 operates for a certain period of time to slightly convey the banknote by a certain amount (for example, 1 to 2 cm). As a result, the tip side of the bill is placed on the rollers 4a and 4b.
The rear end side continues to be further transported by the first transport mechanism 3.

When the rotation of the second conveyance mechanism 4 stops, the shaft 13b is rotated by the second rotation mechanism, and the picking mechanism 5 rotates once in the clockwise direction in FIG. Make it bend.
That is, when the picking mechanism 5 rotates, the rear part of the banknote is transferred from the first conveyance mechanism 3 to the second conveyance mechanism 4.
Even though it is being conveyed toward
Moreover, as the retrieval mechanism 5 rotates, the side portion 5a of the retrieval mechanism 5 separates downward from the bottom surface of the endless belts 8a, 8b, so first the rear part of the banknote begins to curve downward little by little, and then the banknote When the rear part comes off the endless belts 10a, 10b and is pushed by the rotating pulling mechanism 5,
The rear part of the banknote hangs further downward, and then the retrieval mechanism 5 presses the banknote against the guide 6 with the rollers 20, 20 and rotates to the original position, as shown by the two-dot chain line in FIG. In this way, the rear part of the banknote is bent downward along the guide 6. When the retrieval mechanism 5 rotates, the upper endless belts 8a, 8b prevent the rear portion of the banknote from bending upward.

When the retrieval mechanism 5 rotates once, the rear portion of the banknote is deflected downward from the banknote transport path by the transport mechanism 3.

When the next banknote is fed from the banknote processing apparatus 1 after the retrieval mechanism 5 has rotated once, the first transport mechanism 3, the second transport mechanism 4, and the retrieval mechanism 5 operate in the same manner as described above. In this case, the second transport mechanism 4
Since the banknotes (the banknotes fed first) and the second banknotes (the banknotes fed next) are conveyed by a certain amount at the same time, and the first banknote has already been conveyed by a certain amount, the second banknote is
The banknote is stacked on top of the first banknote in a state shifted upstream from the first banknote, and the rear portion is deflected downward along the guide 6 by the drag mechanism 5.

Thereafter, each time a banknote is fed from the banknote processing device 1, the first transport mechanism 3, second transport mechanism 4, and retracting mechanism 5 operate as described above to sequentially shift the banknotes by a certain amount from each other. Arrange them so that they are stacked one on top of the other. The banknotes arranged in this way are conveyed to a confirmation window or a safe in a stacked state.

Note that in the above embodiment, a drive roller and a pinch roller are used as the second conveyance mechanism 4;
A conveyance mechanism using an endless belt can be used. Moreover, when the conveyance mechanism in the banknote processing apparatus 1 uses an endless belt, the conveyance mechanism 3 may be shared.

Effects of the invention As described above, according to the invention, a pair of endless belts are used as the first conveyance mechanism, and the lower endless belt is separated from the second conveyance mechanism, and a fan-shaped tracing mechanism is provided between them. Furthermore, since one side of the drag mechanism is extended toward the second conveyance mechanism to guide the banknotes, the banknotes fed to the first conveyance mechanism do not jam during conveyance. Therefore, banknotes can be reliably transported to the second transport mechanism. In addition, since the rear part of the banknote is bent downward by the rotation of the pulling mechanism while it is being held in the second conveyance mechanism, the holding position of the banknote does not tilt, and the banknote is subsequently fed. can be reliably superimposed on the upper surface of the previously fed banknote, and therefore, with a simple mechanism, it is possible to reliably stack and align multiple banknotes with their tips regularly shifted from each other. .
