Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper sheet processing machine, and more particularly to stacking paper sheets to be conveyed one by one and then collectively conveying them to a predetermined location such as an outlet. The present invention relates to a sheet conveying device.

[0002]

2. Description of the Related Art In a bill handling machine, bills fed one by one are stacked in a stacking unit, and the stacked bills that have been stacked are collectively transported to an outlet or the like. There is an opportunity (for example, JP-A-58-195285).

In the above-mentioned processing machine, the banknotes are fed one by one from the storage section and accumulated in the accumulating section, and then the accumulated banknotes are raised and pressed against the conveying belt, and the conveying belt and the conveying belt are opposed to each other from the accumulating section. Stacked banknotes are gripped between a conveyor belt (or roller) provided and then conveyed and ejected to an outlet or the like.

[0004]

However, in the above-described conventional processing machine, the accumulated banknotes are conveyed at a constant conveying speed from the time when the banknotes are transferred between the upper and lower conveyor belts to the time when the banknotes are ejected to the outlet or the like. Therefore, when the number of stacked banknotes is large, the banknotes are displaced in a stepwise manner while being conveyed while the upper and lower conveyor belts are not easily inserted, and it is difficult to eject the banknotes in an orderly and accumulated state.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to provide an accumulated paper sheet conveying apparatus capable of conveying accumulated paper sheets to a predetermined place without disturbing the accumulation state. According to the present invention, as a means for solving the problem, the carrying speed at the time of transferring from the stacking unit to the carrying device is made variable according to the number of stacked paper sheets, and the carrying speed is increased when the number of stacked paper sheets is large. This is because a speed control unit that drives the conveying device is slower and the speed is faster when the number of sheets is small. Preferably, the transfer speed of the transfer device at the time of delivery is set to high speed or low speed depending on whether the number of stacked sheets is less than or equal to a predetermined number.

[0006] As a result, when the number of stacked sheets is large, they are gripped slowly, so that the stacked sheets are conveyed in an orderly stacked state without shifting in a stepwise manner, and the number of stacked sheets is increased. When the amount is small, it is gripped at a high speed, and it is possible to prevent the conveyance efficiency from decreasing.

Therefore, in the case of a processor for ejecting banknotes, when the banknote is ejected to a length such that it can be grasped by hand, the end faces of the banknotes are aligned and it is easy to grasp.
Also, if the number of collected sheets is small, it can be sent at a high speed, so that the processing time need not be unnecessarily long.

... is pivotally supported. Regarding the receiving plate 76, FIG.
4, as shown in FIG. 17, the first rising portion 74 of the base 74A.
Shaft 78 of roller 78 inserted at the upper end of A ₁ , 74A _1.
a is inserted through the bracket portions 76a, 76a of the receiving plate 76, and the compression spring 74B is interposed between the lower surface of the receiving plate 76 and the upper surface of the base 74A. Further, a pin 74A ₃ planted in the _second rising portion 74A ₂ of the base 74A is inserted into an arcuate long groove 76b formed in the bracket portion 76a, and normally the pin 74A ₃ is urged by the compression spring 74B.
And the lower end of the long groove 76b are engaged with each other, so that the receiving plate 76 maintains a horizontal posture with respect to the base 74A. Also, due to the banknotes accumulated on the receiving plate 76, the receiving plate 76 is attached to the base 74A by the shaft 7
8a will be swung downwards against the compression spring 74B.

One end of the sliding body 74 is provided with a shaft 7 on the side of the machine body 1.
A swing lever 80 supported by 9 so as to be swingable in the vertical direction.
A cam follower 83, which is connected to the other end of the swing lever 80 via a shaft 75 passing through the elongated hole 81, is attached to an intermediate position of the swing lever 80, and is shown on the peripheral surface of a cam 85 rotated by a motor 84. The swing lever 80 is swung up and down by the rotation of the cam 85, and the base 74A and the receiving plate 76 are moved up and down over the stroke b.

Two upper belts 86 are arranged side by side in the width direction of the machine body 1 so as to cover the entire length of the receiving plate 76 in the longitudinal direction and to reach the immediate vicinity of the ejection port 2, in other words, from the ejection port 2 to the recovery port 3. The support plate 76 is stretched to
88A (fixed position) provided at a position slightly closer to the outlet 2 side of the outlet 2 side of the temporary holding section 17 near the end of the outlet 2 side and vertical movement provided near the outlet 2 A lower belt 87 is stretched between the possible pulleys 88, and a banknote is sandwiched between the upper and lower belts 86 and 87 and sent to the outlet 2 (or collected from the collecting port 3). Is configured. The throwing out or collecting here means not a state in which the banknotes are completely discharged, but a state in which a part of the banknotes is projected and held from the discharging port 2 or the collecting port 3 to the outside. The pulley 86
The positions of A, 86B and 88A are all fixed.

On the other hand, the outlet 2 of the lower belt 87
The pulley 88 on the side has its shaft 88a on both side plates 1a, 1a.
It is supported so as to be vertically displaceable along the long holes 1b, 1b, and is normally biased to the upper belt 86 side by the spring 89 as shown in FIGS. 18 and 19 so as to descend according to the amount of bills. It is configured. Reference numeral 90 denotes a fixed intermediate roller that is in contact with the upper surface of the upper belt 86 on the lower traveling side at a position corresponding to the intermediate position of the lower belt 87 in the front-rear direction, and cooperates with the pulley 86B to collect the accumulated banknotes. It has a role of keeping the upper surface position constant.

Therefore, during the temporary holding operation when the banknotes are thrown out, the receiving plate 76 is placed in the lowered position (the position shown by the solid line in FIG. 14), and the storage units 8 ₁ ,
The banknotes delivered from 8 ₂ by the delivery means 15 and 15 are sent to the temporary holding section 17 through the transport path 16.
It is accumulated on the rollers 78 of the receiving plate 76. In addition,
If dispenses the bills of both housing portions 8 _1, 8 _2, dispensing operation earlier from one of the housing portions _81, 82 with priority is performed, one bill on the conveying path 16 Each of them is conveyed at a predetermined interval.

In this way, when a predetermined amount of banknotes are temporarily held and the dispensing approval button is pressed, the motor 84 is activated and the cam 85 is rotated, and the sliding member 7 is moved through the swing lever 80.
4 is raised and the bill on the receiving plate 76 is pressed against the lower surface of the upper belt 86 (FIG. 16). At this time, the receiving plate 76 is
A banknote is placed in a swinging position on the base 74A. Next, by rotating the upper belt 86, the bill P is transferred to the upper belt 8
The upper belt 86 and the lower belt 87 are fed out while being sandwiched between the lower surface of 6 and the rollers 78, 78 of the receiving plate 76.
The paper money is delivered and conveyed between and, and the ejected bill is stopped and held in a state of partially protruding from the ejection port 2. When the banknotes thrown out to the outlet 2 are not taken out and are to be collected, the upper belt 86 and the lower belt 87 are both reversed while the receiving plate 76 is in the raised position to be collected.
And the bill is stopped and held as a state in which a part of the bill projects to the outside. When the banknotes in the temporary holding section 17 are directly collected, the receiving plate 76 is raised and then the upper belt 86 is reversed so that the banknotes are ejected to the collection port 3 as shown in FIG. It is stopped and held in the state.

In sending the bills to the outlet 2,
The sensors S ₆ and S ₆ provided on the inside of the outlet 2 are used for the bill P.
When a predetermined time elapses after the tip of the banknote P is detected and the tip of the banknote P is a 1,000-yen banknote (banknote length L ₁ ) from the outlet 2, c, 10,000-yen banknote (banknote length In the case of L ₂ ), only d is projected from the outlet 2 and stopped.

Further, the driving speed of the belt of the conveying device 4 is controlled as shown in FIG. That is, in FIG. 21, when the number of banknotes P is less than 50, the upper and lower belts 86,
The speed at the time of being pushed in for 87 is increased like the speed e, and the constant speed (conveyance speed f) is set by the timer setting. This constant speed conveyance speed f is also set to a high speed v ₁ . 50 or more banknotes P and 110 (the maximum storage amount in the temporary holding unit 17 is 110
(Because it is one sheet), the biting speed is slowed down as compared with e like g, and the constant speed transport speed h is also set to slow speed v ₂ . The gripping area at the time of bill ejection is a period from the exit of the bill to the intermediate position between the pulley 88A and the pulley 90, and the speed of the period is e Alternatively, as g, the period is set by a timer.

As another control method, as shown in FIG. 22, when the number of banknotes is less than 50 and when the number of banknotes is 50 or more, only the gripping speeds are e and g (speeds of less than 50, e and 50). The speed may be changed as in the case of more than one sheet, and the constant speed feeding may be the same speed v ₁ of the speed f. Further, at the time of collection, the gripping speed is slowed down as indicated by g in both of the examples of FIGS. 21 and 22 regardless of the number of sheets.

If the transport speed of the paper sheets is slowed down immediately before the ejection as in the illustrated embodiment, the paper sheets will not suddenly pop out from the dispensing port, and it is possible to prevent the user from being surprised. .

The holding period at the time of collection will be described. The holding period is the same banknote length as the holding period at the time of dispensing, but there are two types of collection, and the storing sections 8 ₁ , 8 are provided. _There are cases in which the _second bill is collected in the temporary storage unit 17 and collected, and there is a case in which the bill sent to the outlet 2 is not taken out by an operator such as a customer and is collected as an uncollected bill. In the former case, the bills are directly collected from the temporary holding section 17 to the collecting port 3, so that the bill holding plate 76 is used during the bill holding period.
78 is a moving distance of about two rollers 78. In the latter case, it is a period until the trailing edge of the bill (the leading edge at the time of collection) reaches below the roller 90. Note that the speed during the gripping period may differ depending on the amount of bills (see FIGS. 21 and 2).
2) The reason why the speed in the constant speed period is made different depending on the amount of bills (FIG. 21) is to prevent the bills from being slightly misaligned with each other when a large amount of bills is conveyed during conveyance of the accumulated bills, and to prevent this. .

FIG. 23 is a control block diagram, in which the transfer speed setting unit is operated by inputting a dispensing a signal or a recovery b signal from the dispensing number counting unit 93 and the transfer start command unit 94 to the transfer control unit 92 of the control unit 91. The speed of 95 is set, the motor M is driven through the setting unit 95 and a timer, and the upper and lower belts 86 and 87 are driven at a constant speed through a drive transmission means (not shown) to change the speed of the motor M. As a result, the speed of both belts 86 and 87 is controlled while maintaining a constant speed relationship. The speed change command is based on the command from the timer.

If the bill P has been thrown into the throw-out port 2 and the bill P cannot be removed even after a predetermined time has passed,
As described above, the upper and lower belts 86 and 87 are reversed to be sent to the recovery port 3 for recovery processing.

[0056]

As described above, according to the present invention, when the number of sheets transferred from the stacking unit to the conveying device is large, the conveying speed is slow, and when the number is small, the conveying speed is high. Therefore, it is possible to allow the user to easily grab when he / she grabs it from the dispensing port or the like, without making a staircase-like deviation and keeping it in an orderly gathered state. Further, the conveying speed is variable according to the number of accumulated sheets, and especially when the number of sheets is small, the conveying speed is high, so that the processing time can be shortened.
