Abstract

PURPOSE:To simultaneously measure the number of paper moneys, the bending part of the paper money and the swelling of the paper money over a wide range by detecting the presence or absence of the paper money and the abnormal dimension of the paper money by plural sensors for a paper money housing pocket, pressing an inserted medium with fixed pressure by a pressing board, whose dimension is almost same as the paper money, and detecting moving quantity by the sensor. CONSTITUTION:The paper money is housed to a hopper 1a and a housing condition is detected by a size sensor 8. A housed paper money 5 is pressed with the fixed pressure by a spring 10 and the stroke of a link 10 is detected by a width sensor 9. After the cover of a money incoming and outgoing port is closed, it is detected by the sensor 8 whether the paper money is correctly put in the hopper or not. After that, the paper money is clamped by a pressing board 6 and the thickness or the bending part of the paper money is detected again by the stroke of the pressing board 6. Accordingly, the paper money is double checked. Thus, the paper money having strongly bented part or the bank notes, whose number is >= a rated number, can be detected in an entrance and exit part.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a medium abnormality detection mechanism at a deposit/withdrawal port in a banknote handling device.

[Conventional technology]

Detecting banknote abnormalities at the deposit/withdrawal opening in conventional banknote handling devices uses a large number of sensors inside the banknote storage hopper to convert the presence or absence of banknotes into sensor ON/OFF states when the customer is setting banknotes or removing banknotes. Generally, patterns are detected, and folds and thickness of banknotes are not taken into consideration.For foreign objects with abnormal dimensions, multiple sensors are used to detect foreign objects using the same method as above. Foreign objects such as banknotes and coins are dug out of the banknote storage pocket using vibration or the like.

It is also disclosed in Japanese Patent Application Laid-Open No. 61-291370. There is a conventional technique, but this conventional technique includes an inlet/outlet section for taking in and out of a banknote exchanger, a counting section for counting banknotes, a storage section for storing banknotes, and a structure between the input/exit section, the counting section, and the storage section. and a conveyor for selectively delivering banknotes.

At the time of a payment transaction, when the payment amount is specified, the conveyor takes out the banknotes all at once from the hopper of the storage section, inspects and deposits the specified number of bills in the counting section, and transfers them all at once to the entrance/exit section by the conveyor. In addition, when depositing banknotes, when the banknotes to be deposited are put into the bank at the entrance/exit section, the banknotes are delivered to the conveyor all at once. If the number of bills to be passed is too large, the structure of the carrier becomes large, which not only increases cost but also takes up a large amount of space. Furthermore, when transferring banknotes that are crooked or have large losses, there is a high possibility that problems such as jams during counting and failures in delivery occur.

[Problem to be solved by the invention]

The above-mentioned conventional technology does not give much consideration to the folds and banknote thickness, and strongly folded banknotes are difficult to separate and are prone to problems such as misfeeding. When doing so, problems such as jams are likely to occur due to the curls.

Regarding the thickness of banknotes, if more banknotes than a predetermined transaction number are inserted, they must be returned, but this can be detected at the deposit/withdrawal port. In addition, the thickness is thick, that is, M
The banknotes may be too large or too large, which can easily cause a jam. The present invention improves reliability and reduces processing time by clamping the above-mentioned folds and thickness under constant pressure with a pressure plate at the deposit/withdrawal port, and by returning items that exceed a specified stroke as an abnormality on the spot. The goal is to make it shorter.

In the above-mentioned conventional technology, foreign objects such as coins or foreign objects in an abnormally inserted state are detected by vibration or by detecting them with a plurality of sensor sensors. , by detecting abnormal dimensions, abnormal thickness, etc.
The purpose is to perform double detection and make it highly reliable.

[Means for solving rlM]

In order to achieve the above purpose, multiple sensors are used to detect the presence or absence of banknotes and abnormal dimensions in the banknote storage pocket.
By pressing the inserted medium at a constant pressure with a pressure plate that is approximately the same size as the banknote, and detecting the amount of movement with a sensor,
The maximum thickness of the entire banknote, that is, the number of banknotes, folds, and bulge of the banknote can be measured simultaneously over a wide range.

Foreign objects other than banknotes (such as coins) can also be returned or otherwise processed if the pressure plate can be prevented from moving. Furthermore, foreign objects, bills, etc. that are slanted in the storage pocket can be straightened by pressing them with a pressure plate, making them easier to detect with a sensor, and also making it possible to straighten the curls of bills, etc.

As a result of the above, it is possible to return and reinsert banknotes that are likely to cause trouble at the input/output port, thereby improving the reliability of the entire device.

In addition, using the above-mentioned detection means, the presence or absence of banknotes inserted into the deposit/withdrawal slot by the customer is detected by multiple sensors in the storage pocket after insertion, and then re-detected after being pressurized by a pressure plate. Further reliability improvements can be achieved by performing double checks.

[Effect]

In the present invention, as described above, abnormal dimensions can be detected by a plurality of sensors placed in the pocket storage section.1. Once again, the inserted banknotes are pressed to a constant pressure with a pressure plate that is approximately the same size as the banknotes, and the amount of movement can be detected by a sensor. Reliability can be improved by preventing large bulge banknotes from being mixed in and reducing banknote jams and rejection rates.

In addition, as mentioned above, it is possible to identify abnormal dimensions of improvised items in the main body of the deposit/withdrawal unit using two senses, pressure plate senses, etc., so that it can be determined on the spot. Since the amount of movement (the belt type has a large amount of movement) is reduced, reliability can be improved.

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

Before explaining the present invention in detail, a banknote handling device using the present invention will be explained. As shown in FIG. 10, the banknote handling device of the embodiment includes an entrance/exit section l, a counting section 2,
It is configured to include a storage section 3 and a transport body 4.

The input/output section 1 has a hopper 1a for a user to input banknotes 5 during a deposit transaction and for the user to receive banknotes 5 during a payment transaction, and is located at the upper front part of the device. It is installed in

The counting section 2 is configured to inspect and count banknotes during a transaction, and is installed at a rear position facing the entrance/exit section 1. The counting section 2 includes intake hoppers 2a and 2b that take in banknotes to be transacted when the banknotes are transported, a main conveyance path 2C that conveys the taken banknotes, and a main conveyance path. It has a discriminator 2d for discriminating banknotes passing through 2C, and an inspected hopper 2e+2ft 2g for sorting and holding the discriminated banknotes by type.

The receiving hoppers 2a and 2b are configured to take in banknotes of 10,000 yen, 5,000 yen, and 1,000 yen, respectively, during a payment transaction, and to take in all types of deposited banknotes during a deposit transaction. There is. The discriminator 2d detects the denomination of a banknote when the banknote passes through the main conveyance path 2c, and also detects whether the banknote is a genuine banknote or not, and also detects dirt on the banknote,
The system detects damage and distinguishes between banknotes that can be used for transactions and banknotes that cannot be used. The inspected hoppers 2e and 2f hold 1,000 yen and 5,000 yen banknotes and 10,000 yen banknotes by type, respectively, during a deposit transaction.
g is designed to accumulate and hold counterfeit bills and banknotes that are unusable. In addition, the inspected hopper 2e is configured to deposit and hold bills to be paid all at once, regardless of the type of bills, at the time of a payment transaction.

The storage section 3 has storage hoppers 3a+3b for storing banknotes by type, and is installed below the counting section 2. The hopper 3a stores 1,000 yen banknotes to be used for payment transactions, and the hopper 3b stores 10,000 yen banknotes to be used for payment transactions and deposited 10,000 yen banknotes, which are stored in the storage section. 3, 3a and 3b are arranged in the vertical direction in this order.

Next, it will be explained with reference to FIG.

The conveyor 4 has a hand 4a that collectively grips banknotes, and a drive source 4b that moves the hand 4& between the entrance/exit section 1, the counting section 2, and the storage section 3, and is capable of handling banknotes. He is trying to convey it to each part 1-3 based on the type.

That is, the hand 4& is connected to the input/output M1 during the deposit transaction.
When the banknotes are put into the hopper 1a, the banknotes are grasped all at once, conveyed to the take-in hopper 2b of the counter 2, and then transferred to the respective inspected hoppers 2e and 2f by the counter 2. When the banknotes are sorted, each inspected hopper 2i 2
He is trying to convey the banknotes on f to the corresponding hoppers 3c and ab of the storage section 3. In addition, when a payment amount is specified during a payment transaction, the banknotes are collectively grasped from the hoppers 3a and 3b of the storage section and conveyed to the receiving hoppers 2a and 2b corresponding to the counting section 20. When a number of banknotes corresponding to , are sent to the inspected hopper 2e at once,
The sent-out banknotes are conveyed to a hopper 1a at an entrance/exit section 1. In that case, the hand 4a transfers the hoppers 3b of the storage section 3 to the respective intake hoppers 2a+2b of the counting section 2 in advance so as to reduce the time required for payment transactions.

3a, and in the case of a deposit transaction, the bills in the receiving hopper 2b are transported to the corresponding hopper 3a in the storage section 3.
They will be transported to the hospital and temporarily returned to the hospital.

Therefore, the purpose of the medium abnormality detection means in the entrance/exit part l of the embodiment is to improve the reliability of handing over the banknotes to and from the hand 4a that collectively grips them. The main purpose is to ensure that the item is returned.

Next, the deposit/withdrawal port l using this embodiment will be explained with reference to FIG. Reference numeral 7 denotes a lid for taking in and out bills with customers, and when inserted, it opens as shown in this figure, and after insertion, it closes in the direction of the arrow. Also, when dispensing, there is a pause, and after taking out, the hopper 1a closes.The input items (banknotes) are stored in the hopper 1a, and the size sensor detects the storage state. A spring 10 heats the link 11 at a constant rate, and a width sensor 9 detects the stroke of the link 11.

A series of this operation will be explained with reference to flowcharts in FIGS. 6 and 7. Conventionally, as shown in Figure 7, after inserting banknotes and closing the lid,
A sensor is used to check whether there is a person correctly inside the hopper. If OK, the next transaction is performed. If not, the lid is opened again and the customer is reloaded.0Example of the present invention So,
After closing the lid of the deposit/withdrawal section, use a sensor to check whether the deposit is properly in the hopper, then use the heating plate 6 to
The banknotes were clamped and the thickness and curl of the banknotes were checked using 60 strokes of the pressure plate, making it a double check. If something goes wrong, close the lid and put it back in.

Examples of sensor placement at the main deposit/withdrawal port are shown in Figures 1 and 2, and abnormal and normal sensor patterns are shown in Figure 3! Shown in J.

As shown in the flowchart in FIG.
2. Watch it on PS3 Kai 4. At this time, in normal condition, a is shown in Figure 3.
It will be like this. In addition, when an abnormality occurs, the condition will be as shown in Fig. 3 b-cad, and the lid will be opened and the liquid will be charged again. In the conventional case, this state was regarded as a normal ticket and the transaction was performed, but in the present invention, the reliability can be increased by performing steps b and c-d in FIG. Hereinafter, cases of abnormality will be explained using examples.

FIG. 7(A) shows state b of the sensor pattern in FIG. 3, indicating that the banknote 5 was smaller than the standard size. This could be due to foreign objects other than the banknote or the banknote being bent. Note that this example exists in addition to this figure.

Next, as shown in FIG. 8(B), a foreign object 9-
The detection means when a to 9-c are inserted will be explained.

Figure 8 (B) shows a foreign object 9-
The detection method when a is included is shown. By clamping with the pressure plate 6, the foreign object 9-a is corrected to form the sensor pattern C in FIG. 6, and the foreign object is detected. Figure 8 (C) below shows a foreign object detected in the hopper after the slanted object was turned vertical. FIG. 8(D) shows a broken object that has been straightened and a foreign object detected. In either case, the detection means of the present invention mounted on the pressure plate 6 corrects the foreign matter to detect it.

Next, regarding sensor pattern d in FIG.
This will be explained along line A-B in the figure.

Here, the detection stroke XO of the pressure plate is set in advance to XN. If it is larger than XN, it is returned to the customer as an abnormality and reinserted. A in FIG. 9 is an example in which more than a specified number of banknotes 5 are inserted, and after applying a certain pressure with a pressure plate,
In this example, the x1 stroke is larger than the specified XN, so it is considered abnormal.

This is effective in preventing the insertion of more than a specified number of sheets. Moreover, FIG. 9(B) shows a case where the banknotes are heavily damaged and are thicker than the same number of banknotes such as official tickets.

Similarly, since the stroke is larger than the specified stroke XN after constant pressurization, it is considered abnormal. FIG. 9(C) is an example in which a banknote 6 with a strong crease is subjected to constant pressure by the pressure plate 6. Since the stroke after pressure is larger than the specified stroke XN, it is regarded as abnormal.

Further, FIG. 9(D) is an example in which the foreign matter input object 9-d is pressurized by the pressure plate 6 and is deemed to be abnormal because it becomes larger than the specified stroke XN. This foreign substance refers to a foreign substance that did not fall off due to vibration or the like.

The examples given above are examples that are likely to cause trouble if they are considered normal, and are important means for increasing the reliability of the device.

In addition to the above embodiment, if a strain gauge or something like a mud switch that combines a conductive rubber and a switch part is used as the pressure plate, it is possible to determine which part is pressurized the most.
In addition, it is possible to determine in what part the medium is located, and therefore, it is possible to determine what kind of medium it is and how it is formed. Therefore, the plurality of sensors in the pocket storage section can be eliminated, and abnormality determination at the deposit/withdrawal section becomes more reliable, leading to improved reliability.

〔Effect of the invention〕

According to the present invention, strongly folded banknotes and banknotes exceeding a specified number can be detected at the entrance/exit section, and return/re-insertion processing is possible, reducing failures, increasing operating rates, and shortening processing time. In addition, the presence or absence of banknotes in the hopper is detected and a pressure plate is used to
By re-detecting, it is possible to detect two tumors, thereby reducing the number of failures, increasing the operating rate, and improving reliability.
