Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention [Object of the Invention] (Industrial Application Field) The present invention is directed to an automatic transaction device that automatically deposits and withdraws banknotes and coins using a cash card, for example. This invention relates to a shutter device that opens and closes the deposit and withdrawal port of Et (ATV).

(Prior art) The shutter that opens and closes the deposit/withdrawal port of an automated teller machine (hereinafter referred to as ATM) must be closed manually by the customer when depositing money, including confirmation that the deposit is complete. When withdrawing money, if the detection of remaining banknotes became ``no'', the bank automatically closed the bank, assuming that the banknotes had been handled. If a customer fails to take out a banknote during automatic closing, the customer may stick his or her hand in again, so to avoid getting his or her fingers caught, close the shutter halfway and then slowly close the shutter. A slip mechanism was installed in the drive system, so that even if a customer's finger were to get caught in the shutter, they would not feel any pain.

(Problems to be solved by the invention) However, as ATVs become widespread and are operated on holidays, etc.
With sales counters now closed, customers who previously were not good at operating mechanisms such as ATVs are now forced to use them, and are having to forget to close the shutters when making deposits and reinserting their hands when withdrawing money. This has led to an increase in the number of people getting their hands caught, which has resulted in problems such as not being able to operate smoothly and making customers feel uneasy.

The present invention has been made based on the above-mentioned circumstances, and its purpose is to enable the shutter to be closed immediately after the customer finishes handling banknotes when depositing money or removing bills to be withdrawn. The operation rate is improved by preventing forgetting to close the door, and the processing time of the entire mechanism is shortened.
Even if a customer were to touch or touch the door again, this would be detected and evacuated, thereby providing a safe shutter device for the deposit/withdrawal port.

[Structure of the Invention] (Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a method that, when accepting banknotes,
and a shirt removal device that opens the deposit/withdrawal port during discharging and normally closes the deposit/withdrawal port, and includes a shutter provided to be movable in order to open/close the deposit/withdrawal port, and a shutter drive for driving the shutter. means, a first detection means for monitoring while moving slightly in front of the shutter which is moved in and out by the shutter drive means, and moving in parallel with the shutter; a second detection means for monitoring the position, and a third detection means for monitoring the position of about half the normal height of the banknote; Second
．． and a shutter control means for controlling the shutter driving means by a detection signal from the third detection means, and the shutter control means controls the shutter drive means when the detection signal of the third detection means is "present" after the shutter is opened at the time of deposit. 1. If the detection signal of the second detection means is "absent", the shutter is closed, and when withdrawing money, the first detection means is opened after opening the shutter. Second. If the detection signal of the third detection means is "absent", the shutter is controlled to be closed.

(Function) Since the shutter can be closed immediately after the customer finishes handling banknotes when depositing money or removing banknotes, it is possible to improve the operating rate by preventing customers from forgetting to close the shutter, and also to reduce the overall efficiency of the mechanism. Processing time is shortened, and even if the customer inserts his/her finger or hand again, it can be detected and evacuated.

(Example) The present invention will be described below with reference to the oral surface. In the figure, reference numeral 1 indicates a deposit/withdrawal port formed in the operating section 2 of the money processing device. At a position corresponding to deposit/withdrawal 01, there is a receiving port 3 for receiving banknotes P and coins K in a mixed batch. Coin take-in where P' is taken upwards via the take-in means 4 and coins K are taken downwards via the coin ejection section 5! A banknote 6 is arranged, and a banknote P is also placed.

The structure includes a shutter device 7 that opens the deposit/withdrawal port 1 when accepting coins and discharging banknotes P, and normally closes the deposit/withdrawal port 1.

The money receiving device 6 has the following configuration.

That is, in the figure, 10 is a floor 111 as a supporting member.
is a backup member, and the above-mentioned receiving port 3 is configured between these mutually opposing surfaces.

The floor 10 is formed in an L-shape, and constitutes the front side and bottom of the receiving opening 3, and as shown in the third factor, the lower part of the front side is used for discharging coins. A plurality of large holes 10a serving as the portion 5 are formed.

Further, the floor 10 and the backup member 11 are rotatably supported by the same rotating shaft 12 via oil-impregnated bearings 13 . This rotating shaft 12 is mounted on a frame 14.14 with an oil-impregnated bearing 13.14 as shown in FIG.
The shaft is rotatably supported via a shaft 13, and one end thereof is connected to a pulse motor 15 serving as shaft driving means, so that it can rotate in both forward and reverse directions.

Further, the rotational force of the rotary shaft 12 rotated in a predetermined direction by the pulse motor 15 is independently transmitted to the floor 10 and the backup member 11 via the rotational force transmission means 16 . There is. That is, the rotational force transmission means 16 includes a driven bin 17 that projects from the lower part of the floor 10 and the backup member 11, and a drive bin 18 that projects from the rotating shaft 12 so as to be able to come into contact with the driven bin 17. , a coil spring 19 that is wound around the rotating shaft 12 at its midpoint and connected at both ends to the driven pin 17 and the driving pin 18, and is constantly biased in a direction in which both pins 17 and 18 come into contact with each other. There is.

Therefore, the tension of the coil springs 19 . . . causes the floor 10 and the backup member 11 to move the bins 17 . and 18 are positioned in contact with each other, and by rotating the rotating shaft 12 in the forward and reverse directions, the receiving state with sufficient receiving space as shown in FIG. 1 or the second
As shown in the figure, the device is in a capture operation state.

The backup member 11 includes a drive arm 20 rotatably supported on a rotating shaft 12, a pot supported on the drive arm 20 via screws 21.21, and springs 22, 22, and 23 with different tensions. A back-up plate 24 as a swingable bill pressing section supported by .23
It consists of

This back-up board 24 is made by pasting urethane foam on a structural material and further pasting a polyester film on the surface of the foam. It is formed in a curved state that matches the curve of the rollers 25....

The dimension between the lowest end of the back-up plate 24 and the bottom of the floor 10 is higher than the maximum diameter of the coin, so even if the coin K is standing, the back-up plate 24 will push it. Never.

Also, the tension of the lower spring 23.23 is considerably stronger than the tension of the upper spring 22.22, which is applied to the pivot supporting screw 21.21, so the back The up plate 24 always tries to rotate to the left (counterclockwise) using the screws 21 and 21 as a fulcrum, but is regulated by a stopper (not shown) to maintain the tenth shape.

Moreover, as shown in FIG. 1, the take-in rollers 25...
A part of it has a rubber chip 25a with a high rIl friction coefficient for taking in banknotes, and the upper part of the rubber chip 25a faces with a very small gap the size of one banknote P, and has a circumferential speed of 1/1.

In addition, feed rollers 27 are disposed below the O-roller 25 for taking in the material.

Next, the shutter device 7 for opening and closing the deposit/withdrawal 01 will be explained with reference to FIG.

30 in the figure is a shutter, which is driven by a shutter driving means 31 to open and close the deposit/withdrawal port 1. That is, a rack 33 that meshes with the gear 32 is provided on the lower surface of the shutter 30, and a rack 33 is provided on the lower surface of the shutter 30.
is sandwiched between the gear 32 and the guide roller 34.

The gear 32 is rotated in both forward and reverse directions by a pulse motor 35, thereby causing the shutter 30 to move forward and backward in order to open and close the deposit/withdrawal port 1.

Further, a first detection means 40 for detecting a finger monitors while moving slightly in front of the shutter 30 in parallel with the shutter 30.
is provided. This first detection means 40 is composed of an optical detector composed of a light emitting diode 41 and an optical sensor 42, and monitors the entire area approximately one finger width in front of the shutter 30 in a direction orthogonal to the moving direction of the shutter 30. are doing. Normally, it is in a bright state and outputs a detection signal of "absence", but if the shutter 30 closes or a finger is present, it becomes dark and outputs a detection signal of "presence". .

Furthermore, a second height detection device is provided for monitoring the position slightly above the normal height of the banknotes P inserted from the deposit/withdrawal port 1.
, and a third detection means 44 for residual detection that monitors approximately half the normal height of the banknote P (above the feeding roller 27).

The second detection means 43 consists of an optical detector composed of a light emitting diode 45 and an optical sensor 46, and when the banknote P is properly pressed against the bottom surface of the floor 10, a detection signal of "absence" is output. It is designed to output .

The third detection means 44 includes two light emitting diodes 47.4.
7 and optical sensors 48, 48, and when a banknote P is in the receiving port 3, it outputs a detection signal indicating "presence".

Also, the above 1. Second. Third detection means 40°43.4
The detection signals No. 4 are input to a control 1fi 50 as a control means, as shown in FIG. 4, and these signals can control the rotary shaft driving pulse motor 15 and the shutter pulse motor 35.

Note that 55 shown in FIGS. 1 and 2 is a gate,
When dispensing money, this gate 55 rotates to the right and moves to the position indicated by the two-dot chain line in FIG. The banknote discharging conveyance path 56 is opened, and at the time of deposit, the banknote discharging conveyance path 56 is moved to the solid line position in FIG. It has become.

In addition, 57 is a bill taking-in conveyance path which conveys the banknote P taken in by the taking-in means 4 to the inspection part (not shown) which performs a denomination discrimination|determination etc., and the taking-in state of the banknote P is detected in the middle part. Detection means 58 is provided. Reference numeral 59 denotes a discharge chute for discharging the coins K discharged from the coin discharging section 5 to an inspection section (not shown) that performs denomination discrimination and the like.

Next, the operation of taking in banknotes P and coins will be explained.

When the transaction operation state of the money processing@placement reaches the stage of instructing the insertion of banknotes P and hard IK, the shutter 30 is activated as shown in FIG.
will open automatically. At this time, a sufficient receiving space is formed between the floor 10 and the backup member 11. Then, the user mixes and inserts banknotes P and coins K at once from the deposit/withdrawal port 1 according to operation guidance from an operation section (not shown), and then closes the shutter 30.

When it is confirmed that the shutter 3o is closed and completely locked by a locking device (not shown), the rotary shaft pulse motor 15 moves the rotary shaft 12 in a predetermined direction, that is, in the state shown in FIGS. 1 and 2. Drive to rotate to the left. Initially, both the floor 10 and the backup member 11 rotate to the left as the rotating shaft 12 rotates due to the force of the coil springs 19 of the rotational force transmitting means 16.

As the backup plate 24 of the backup member 11 moves away from the stopper (not shown), the subring 23.2
3 is stronger than 22.22, so it rotates counterclockwise using the pivot support screw 21.21 as a fulcrum.

Then, the floor 10 is first prevented from rotating to the left by a stopper (not shown), and the take-in roller 16 . It has a predetermined positional relationship with the feed roller 22.

When the pulse motor 15 continues to be driven and the rotary shaft 12 continues to rotate roughly, the bins 17 and 17 protruding from the floor 10
The pin 18.18 protruding from the rotating shaft 12 gradually separates from the pin 18.18, thereby winding up the coil spring 19.19 accordingly.

When the amount of banknotes P in the receiving port 3 is large and thick, the upper end of the back-up plate 24 comes into contact with the banknotes P.

At this time, the back-up plate 24 deforms the bill P to match the curve of the take-in roller 25... and takes in the entire bill P with an optimal pressing load. Press on 27...

That is, the total tension of the load ff1Ft that bends the tip of the banknote P, the optimal pressing direction 1iF2 of the back-up plate 24, and the coil springs 22.22 is 1, and the coil spring 2 is
3.23 to the total tension 1', spring 19.1
When 9 is set as 2 for the total tension, the spring constant of spring 22, 23, 19 is set so that Kr--K>Ft 2-F2 F2>F,
The optimum spring can be selected by determining the amount of displacement.

When these springs 22, 23, and 19 are attached, the back-up plate 24 hits the upper end and bends the tip of the banknote P sufficiently, then gradually rotates to the right (clockwise) and eventually As shown in FIG. 2, the state matches the curve of the intake row 525.

On the other hand, since the rotating shaft 24 continues to rotate to the left at this time, the backup member 1
The pin 17.17 protruding from the first drive arm 2o and the pin 18.18 protruding from the rotary shaft 12 are gradually separated, and the coil spring 19.19 is wound up accordingly.

The rotation of the pulse motor 15 is stopped at a position where 2 is generated equal to the predetermined F2, and this state is maintained.

Next, when the intake rollers 25... are rotated, the second and subsequent bills P are squeezed by the reverse rotation of the gate rollers 26..., and the amount of paper money formed between them is about one bill. The sheets are sent out one by one through the gap between the two.

The thickness of the banknotes P in the receiving port 3 gradually decreases as they are taken out, but the pulse motor 15 remains stopped and the coil spring 19 .
With only the tension of 19, the back-up plate 24 gradually follows the intake row 525.

In this way, the banknotes P are sequentially taken out and the operation of taking in the banknotes P is performed until the two optical sensors 48, 48 of the third detection means 44 are "bright", that is, a detection signal indicating that there is no banknote is issued.

On the other hand, if coins K... are mixed in the receiving port 3,
Since the lower end of the back-up plate 24 is positioned higher than the maximum outer diameter of the coin, it does not press the coin K directly.

In addition, when the coins are mixed with banknotes P, they may be pushed through the banknotes P, but since the feed roller 27 is located above the maximum outer diameter of the coin, the upper take-in roller 2
It will not be sucked up to the position of 5....

A large hole 10a serving as the coin ejection section 5 is formed in the lower part of the front side of the floor 10, so that the floor

a... or are pushed by the bill P and are ejected from the holes 10a...J, and fall reliably into the ejection chute 59.

Further, even if the remaining banknotes P are detected, the banknotes P may not come out to the taking-in conveyance path 57.

In such a case, if the pressing force F2 of the back-up plate 24 is increased, the deformation of the banknote P will be eliminated and it will be easier to take it out.

Therefore, in this device, the pulse motor 15 is driven to further rotate the rotary shaft 12 to the left based on the signal from the detection means 58 that detects the state of taking in the banknotes P, thereby winding up the coil springs 19 and 19. The value of 2 will be increased accordingly.

On the other hand, if 2 is set too large, the adhesion between the banknotes P will increase and the overlapping rate will increase, so once this clogging situation is resolved, immediately turn the banknotes to return them to the original optimal F2 value. The pulse motor 15 is driven to rotate the shaft 12 clockwise and return it to its original position.

In addition, when the banknotes P... are all new bills, they tend to come out in reverse, and the so-called "double out" phenomenon, where the banknotes P come out in a continuous chain, tends to occur. In some cases, it is better to reduce the optimum F2, so the pulse motor 15 can be driven to rotate the rotary shaft 12 in the right direction, and K2 can be made slightly weaker.

In any case, with this device, various pressing forces for the backup plate 24 can be selected simply by changing the amount of rotation of the rotating shaft 12, and the pulse motor 15 is used as the power for changing the rotation opening of the rotating shaft 12. Since it is used, subtle adjustments can be made.

Next, after completing the loading, when the pulse motor 15 is driven to rotate the rotary shaft 12 in the right direction, the coil springs 19 that were wound up at first only return to their original positions, but they stick to the rotary shaft 12. The provided pins 18... project from the floor 10 and the backup member 11 of the bin 1.
7... can return the floor 10 and the backup member 11 to their original positions.

In addition, since the common rotating shaft 12 is located below the bottom plate of the floor 10, the receiving opening 3 formed between the mutually opposing surfaces of the floor 10 and the backup member 11 is naturally directed upward. It is possible to construct an extremely user-friendly receiving port 3 that is wide and narrow at the bottom.

In addition, if such a system is adopted in which the rotation shaft 12 is shared, it opens upward, so normally it is necessary to use a parallel link, a cam, etc. to perform the neck shooting operation of the back-up plate 24, but the present invention There are three types of springs 1
By selecting 9.22.23, it is possible to use the screw 21.21, which is the simplest pivot, as a fulcrum, and to make the displacement conform to the curve of the take-in roller 25. Note that the bill pressing surface 24a of the back-up plate 24 is also connected to the take-in roller 2.
5... It is formed with a curve that fits well.

Next, the operation of the shutter device [7] will be described.

In order to open the shutter 30 which is closed at the step of inserting the banknote P, a hole 3 formed on the lower surface of the shutter 3o is used.
The pulse motor 35 is driven so as to rotate the gear 32 meshing with the gear 3 counterclockwise in the state shown in FIGS. 1 and 2.

At this time, the upper surface of the shutter 30 is guided by guide rollers 34, and both side edges are guided by guide means such as rollers.
(not shown), and the shutter 30 can move smoothly without shaking.

A first detection means 40 is attached to the tip of the shutter 30 and monitors an area one finger length in front from the left and right.

Then, in the state where the shutter 30 is open, a "presence" detection signal is output from the third detection means 44 for residual detection, and the first detection means 4o for finger detection and the third detection means 4o for height detection are output. If the detection means 43 of No. 2 outputs a detection signal of "absence", it is assumed that the insertion of banknotes P has been completed, and the shutter 30 is immediately closed.

If the insertion of the banknote P is not completed, for example, if the banknote P is inserted while being grasped by hand, the optical path of the second detection means 43 for detecting the height will be blocked by the hand, and the "present" signal will be signaled. is output, and when you put your finger back in to fix it again after removing your hand, the finger blocks the optical path of the first detection means 4o for finger detection before the shutter 30 hits the finger, and a "presence" signal is generated. Output.

In addition, since the monitoring direction of the first detection means 4o and the monitoring direction of the second detection means 43 are made substantially orthogonal, it is possible to detect every movement of the customer's hand with the minimum necessary amount.

In this way, during the closing operation of the shutter 30, the first detection means 4o for finger detection or the second detection means 43 for height detection
If a "presence" signal is output from either one, the closing operation is immediately stopped, and the opening is reversed by approximately 1 tM. This is because when the shutter 30 comes out when inserting a finger into the deposit/withdrawal slot 01, the user will feel uneasy, so it is better to immediately retreat a little to prevent this. If the "present" state continues, the opening operation continues, and if the "absent" state continues, the closing operation is resumed.

Note that the first detection means 40 for finger detection is the shutter 30
In the state just before closing, the optical path is blocked by the stopper side wall formed at the front edge of the opening of deposit/withdrawal 01, and the state is always "present", so if you constantly monitor this, you will not be able to close it. .

Therefore, the detection operation of the first detection means 40 must be stopped immediately before the shutter 30 is closed. Therefore, for safety, the front end of the shutter 30 and the first
The distance between the sensor and the detection means 40 is set to be less than one finger length (approximately 12 m+).

Next, a case will be described in which the withdrawal banknotes P... are accumulated in the receiving port 3.

When the integration operation is completed, the shutter 30 is opened.

At this time, it is necessary to ensure that the stacked banknotes P... are taken from the receiver, so the banknotes must be held until the third detection means 44 for residual detection becomes "absent".

That is, unlike at the time of deposit, all three detection means 40, 43, and 44 for finger detection, height detection, and residual detection are "absent".
Only then does the shutter 30 start to close. Once the quantity operation is started, these three detection means 40, 43
．． If any one of 44 becomes "present", the closing operation is immediately stopped and the opening is reversed by about 11.

If it continues to be "present", the opening operation continues, and if it becomes "absent", the closing operation is restarted.

In this way, a wide range can be monitored by monitoring in almost orthogonal directions by the two detection means 40 and 43, and by using the pulse motor 35 as the drive #JJm, instantaneous stopping and reversing are possible, resulting in high-speed operation. Accordingly, it is possible to obtain a shutter device with high safety and security.

[Effects of the Invention] As explained above, the present invention provides the following advantages:
A shutter device that opens a deposit/withdrawal port at the time of discharging and normally closes the deposit/withdrawal port, the shutter being provided to be movable in order to open/close the deposit/withdrawal port, a shutter driving means for driving the shutter, and A first detection means monitors while moving slightly in front of the shutter which is moved in and out by the shutter driving means in parallel with the shutter, and monitors a position slightly above the normal height of the banknotes inserted from the deposit/withdrawal slot. a second detection means, and a third detection means for monitoring a position approximately half the normal height of the banknote; and a shutter control means for controlling the shutter driving means by a detection signal from the third detection means, and the shutter control means controls the shutter drive means when the detection signal of the third detection means is "present" after the shutter is opened at the time of deposit. 1. If the detection signal of the second detection means is "absent", the shutter is set to MtllL, and at the time of withdrawal, the shutter is opened and then the first. Second. If the detection signal of the third detection means is "absent", the shutter is controlled to be closed. Therefore, the shutter can be closed immediately after the customer finishes handling banknotes when depositing money or leaving the banknotes being withdrawn, which improves the operating rate by preventing customers from forgetting to close the shutter. The overall processing time for the system is shortened, and even if a customer inserts their finger or hand again, it can be detected and removed, providing a highly secure shutter device for the deposit/withdrawal slot. play.
