Description

[Detailed explanation of the invention] (a) Industrial application field This invention is applicable to the bill dispensing section and bill taking section of automatic teller machines and automatic currency exchange machines used in banking business, for example. This invention relates to a paper sheet feeding device.

(B) Prior Art Taking the above-mentioned banknotes as an example among paper sheets such as banknotes, slips, cards, fixed forms, and securities, the banknote storage section is usually located at the front and stores the banknotes. A feed-out roller is disposed, and a push-out plate is disposed at the rear for biasing and transferring the stored banknotes.

However, since the banknotes that are transferred under the urging force of this pressing plate are stacked vertically in the front and back direction, when they slide on the placement plate and move forward,
The lower edge of the banknote moves against the sliding resistance with the placement plate, causing the lower end to fold during transfer of the banknote. In particular, thin pieces of paper such as banknotes are weak, and when a large number of sheets are stacked and stored, the sliding resistance with the mounting plate increases and the phenomenon of folding of the lower edge becomes noticeable. If it gets caught when feeding out,
This was the cause of empty rolls, double rolls, jams, etc.

(c) Purpose of the invention This invention eliminates the phenomenon of folding of the bottom edge of paper sheets that hinders the feeding of paper sheets, and also eliminates the phenomenon of paper sheets falling forward by forcibly pulling the bottom edge of the paper sheets forward. To provide a paper sheet feeding device capable of efficiently guiding paper sheets to a feeding side and surely feeding them one by one.

(d) Structure of the device This device stores paper sheets stacked vertically in the front-rear direction, and includes a pressing plate positioned at the rear in the stacking direction to transport the paper sheets forward, and a pressing plate positioned at the rear in the stacking direction to transport the paper sheets forward. a loading and conveying belt located at the bottom of the paper sheet storage section, which places and conveys the paper sheets on the upper surface thereof to the forward delivery side; A conveyance control means for controlling the feeding of paper sheets while forcibly pulling the lower end of the paper sheet forward by setting the loading and conveying belt at a conveyance speed faster than the biasing transfer speed of the pressing plate. It is characterized by being a feeding device.

(e) Effects of the invention According to this invention, a transport control means is provided which sets the transport speed of the loading transport belt faster than the urging transport speed of the pressing plate that urges and transports paper sheets forward. Even if the lower edge of the paper sheet tends to bend due to the pressing force of the pressing plate, the lower edge side of the paper sheet is forcibly pulled forward by the drive of the loading and conveying belt, and the paper sheet is transferred. Even if the posture of the paper sheets tends to bend forward during the process, this can be satisfactorily corrected, preventing the paper sheets from falling forward and maintaining the stacked state without bending the lower ends.

Therefore, even if the paper is a weak and thin piece of paper such as a banknote, the storage condition suitable for feeding is always maintained, and smooth feeding is ensured to prevent empty sheets, double sheets, jams, etc. I can do it.

Furthermore, due to the conveying action of this belt, the lower edge side of the paper sheet is accurately fed to the forward feeding roller section, resulting in a high-performance feeding device in which the feeding performance at the feeding section is further improved.

(F) Embodiment An embodiment of this invention will be described below in detail based on the drawings.

The drawing shows an example in which a bill dispensing device is applied to a cartridge that is attached to and detached from an automatic teller machine. A storage section 13 is formed to control the feeding of the material.

This storage section 13 stores banknotes 12 in a horizontally elongated upright state stacked in the front-rear direction while leaning against a press plate 14 and aligned on a loading conveyor belt 15. The banknotes 12 stored therein are urged to be transferred to the payout side by the urging and transfer action of both.

The above-described loading and conveying belt 15 includes a driving pulley 16 on the front stage side in the feeding direction and a driven pulley 1 on the rear stage side.
7, and are arranged horizontally parallel to a pair of left and right (however, for convenience of illustration, only one is shown in the drawing), corresponding to the horizontal length of the banknote 12.

Furthermore, the upper surface of this horizontal placement and conveyance belt 15 is set as a belt placement surface on which banknotes 12 are placed and conveyed, and the position parallel to this belt placement surface is slightly sunken from the belt placement surface. A bill placing plate 18 is installed to supplementally place the banknotes 12 placed on the placing and conveying belt 15.

The above-mentioned pressing plate 14 is biased and supported toward the feeding side via a biasing mechanism 20 supported by a slider 19, and this slider 19 is supported by the above-mentioned banknote placement plate 18.
It has several guide rollers 21 that sandwich the slider 19 from above and below, and the slider 19 and the fixing pin 2 on the front stage side.
The slider 19 is allowed to slide forward along the banknote placement plate 18.

Further, each biasing lever 24 is pivotally connected between the slider 19 and the pressing plate 14 in a link type,
The pressing plate 14 is further provided with a biasing force by the biasing force of a biasing spring 25 wound around one pivot portion of the biasing lever 24.

This pressing plate 14 is provided in a backwardly inclined state suitable for feeding out the banknotes 12, and the pressing plate 14 in this backwardly inclined state
Bills 12 are loaded leaning against the front side of the machine.

Coaxially with the above-mentioned driving pulley 16, a pulley (not shown) for transferring the pressing plate is provided via a one-way clutch.
In addition, a pulley (not shown) for transferring the pressure plate is similarly arranged coaxially with the driven pulley 17, and a pressure plate transfer belt (not shown in the figure) is installed between the front and rear pulleys for transferring the pressure plate. (not shown) is stretched, the above-mentioned slider 19 is connected to this pressure plate transfer belt, and the pressure plate 14 is transferred via the pressure plate transfer belt and the slider 19 by the spring force of the coil spring 23. .

The diameter of the front pulley for transferring the pressure plate mentioned above is
D2, the diameter of the drive pulley 16 is D1, and the pressure plate 1
4 moves forward a distance Lmm, the pulley for transferring the press plate rotates L/2πD2, and the drive pulley 16 rotates L/2πD2.

Therefore, the loading conveyor belt 15 is (L/2πD2)×
Since it moves by 2πD1=(D1/D2)L, D2<D1
By setting this, it is possible to quickly transport the loading and transporting belt 15 with respect to the pressing plate 14.

By the way, at the front end opening of the cartridge 11 corresponding to the feeding side of the storage section 13, there is a feeding auxiliary roller 26 that faces the center of the front end surface of the banknotes 12 that are arranged and stored in a rearward tilted state, and a rearward tilted banknote 12.
A feed-out roller 27 is disposed opposite to the lower front end surface of the banknote 12, and normally, the lower end of the banknote 12 receives a biasing action suitable for feeding out the press plate 14 and the placing and conveying belt 15. and are faced with each other. Furthermore, a feed-out control roller 28 equipped with a friction pad for feeding banknotes 12 to a subsequent stage is provided on the opposing surface facing the lower end of the feed-out roller 27 .

The feeding roller 27 is provided with a friction member made of a material having a high friction coefficient such as a rubber material on a part of the circumferential surface of the roller 27, so that one rotation of the roller 27 feeds out one bill. There is.

In the figure, 29 is a drive motor, 30 is its drive belt, and when the banknote 12 is fed out, the drive motor 2
9 to drive the above-mentioned placing and conveying belt 15 toward the feeding side, and at this time, the conveying speed of the above-mentioned placing and conveying belt 15 is set to be faster than the urging transfer speed of the above-mentioned pressing plate 14. It is formed so that the lower edge side of the banknote 12 is fed to the payout roller 27 side.

In the banknote dispensing device configured in this way, the banknotes 12 are rotated by the rollers 26 and 27 from the front end dispensing side of the storage section 13 under the pressure of the press plate 14 and the transfer action of the loading and conveying belt 15. By the driving operation, the bill 12 is guided and dispensed diagonally downward in the dispensing direction.

In this case, the banknotes 12 loaded in the storage section 13
However, when the lower end bends due to the pressing force of the press plate 14 during the transfer, the loading conveyor belt 15 is driven in conjunction with the transfer, and this belt speed is adjusted to the feed speed of the press plate 14. By setting the speed faster, the lower edge side of the banknotes 12 is forcibly pulled forward, and the banknotes 12 are transported in a stored state with no lower end folding, which is suitable for feeding, and the phenomenon of the banknotes 12 falling forward is prevented. I can do it.

In particular, by driving the loading and conveying belt 15, the lower edge side of the banknote 12 is sent to the circumferential surface of the payout roller 27, and the sent banknote 12 is fed out more accurately by the rotational action of the payout roller 27. Ru.

As mentioned above, the conveyance speed of the loading conveyor belt is
By setting the biasing movement speed of the pressing plate to be faster than the urging movement speed of the pressing plate, it is possible to reset the banknotes to the storage condition suitable for feeding during the feeding process, and also to efficiently guide the banknotes to the feeding roller part so that the banknotes are always stable. It is possible to maintain the same feeding performance.

In the correspondence between the structure of this invention and the above-mentioned embodiment, the paper sheet of this invention corresponds to the banknote 12 of the embodiment, and similarly, the biasing means corresponds to the coil spring 23 and the conveyance control Although the means correspond to the drive pulley 16, the invention is not limited to the configuration of the above-described embodiment.
