Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a paper sheet dispensing machine. In particular, it uses a paper sheet (for example, banknotes) storage cassette that can be freely attached to and detached from the machine body. This is applicable to a system in which a batch of items is dispensed, temporarily held, and then dispensed at once from a dispensing port with only a portion exposed when dispensing from the cassette is completed.

[Conventional technology]

2. Description of the Related Art A paper sheet dispensing machine (for example, a banknote dispensing machine) is conventionally known as a device that dispenses a desired number of paper sheets (for example, banknotes) of a desired type (for example, denomination).

In such a bill dispensing machine, bill storage cassettes are prepared for each denomination and are removable from the dispensing machine, and the banknotes stored in the cassettes are taken out and dispensed in desired numbers for each denomination, and are temporarily stored. It is designed to be temporarily held in the holding section. When the temporarily held banknotes are completely discharged from the cassette, they are conveyed all at once to the payout port by a conveyor belt system using conveyor means such as a conveyor belt or a conveyor pulley, and some of the banknotes are delivered from the payout port to the outside It is designed to be paid out to the Terror with a portion of the shell exposed.

As a technique for conveying a plurality of bills to such a payout port and causing them to protrude from the payout port, for example, there is a technique described in Japanese Utility Model Publication No. 56-52500. In the system described in this publication, when a plurality of bills are fed out and the tip of the bill is detected by a switch, the conveyance system is temporarily stopped, the shutter is opened, and the bill is conveyed again. The bill is discharged from the discharge port and stopped when the tip of the bill hits the stopper.

[The problem that the idea aims to solve]

By the way, in a banknote dispensing machine having a temporary holding section, paper sheets of each denomination are stacked together in a state that they are held in the temporary holding section, and therefore the paper sheets are piled up all at once when being transported in the conveyance system. It is done in a state where it is done. For this reason, due to deterioration or wear and tear of the upper and lower conveying means that sandwich the stacked banknotes, the stacked banknotes may be conveyed while being disrupted. Also,
When the banknotes are stacked together in the temporary holding section and sent out to the conveying means, the piled state of the banknotes may collapse and the banknotes may be conveyed as is.

If such stacked banknotes are conveyed, especially in a state where they are collapsed in the front-back direction, the banknotes become uneven when they are projected from the payout port, making it difficult for the teller to receive them. In extreme cases, even though the bills at the rear end have not yet reached the outlet, the bills at the front end may fly out from the outlet and fall.

In addition, in the conventional device described above, since the tip is only stopped by the stopper, depending on the relationship between the distance between the conveying pulley and the stopper and the length of the bill, the bill may be thrown away, warped, or bent.
There was a problem that the stacking condition collapsed.

The present invention has been made in order to solve the above-mentioned drawbacks of the conventional device, and provides a paper sheet dispensing machine that prevents paper sheets from being discharged from the dispensing port while the stacked state is collapsed. The purpose is to

[Means to solve the problem]

In order to achieve the above object, the present invention dispenses a desired number of paper sheets from a cassette containing paper sheets, temporarily stores the ejected paper sheets in a temporary storage section, Upon completion of discharging from the cassette, the paper sheets piled up in the temporary holding section are conveyed to the payout port via the conveyor belt system, and a portion of the piled sheets is transferred from the payout port to the outside. The conveyor belt system is stopped in a state where a portion of the sheet is exposed, and the stacked sheet portion located inside the dispensing port is held by the conveyor belt system in preparation for removal of the stacked sheet from the dispensing port. In the paper sheet dispensing machine, the transport state detection sensor detects stacked sheets transported from the temporary holding section to the dispensing port by the transport belt system, and a drive for the transport belt system. a conveyance pulse generator that outputs a conveyance pulse in synchronization with the conveyance pulse, a counter that counts the conveyance pulse while the conveyance state detection sensor detects stacked sheets, and a storage for storing returned sheets. and when the count value of the counting unit exceeds a predetermined reference value, it is assumed that there is an abnormal length due to stacking collapse, and transport of the stacked paper sheets to the dispensing port is prohibited. The present invention is characterized in that it further includes a control section that causes the stacked paper sheets to be collected into the storage section.

[Effect]

In this device, while the conveyance state detection sensor is detecting paper sheets, if the count value of the conveyance pulses emitted in synchronization with the drive of the conveyor belt system is equal to or greater than the reference value, there is an abnormal length. Since the sheets are collected without being discharged because they are considered to have collapsed, paper sheets that have collapsed due to stacking are not discharged.

Among the select pieces 5, 15, . . ., the protrusion 16 of the select piece in the forward position operates the corresponding micro switch when loading the cassette, and the protrusion 16 of the select piece in the retreat position does not operate the micro switch. Therefore, by loading a cassette and detecting the operating state of each microswitch, the denomination set in the machine body 1 can be determined.

FIG. 3 is a block diagram showing the control system. As shown, the CPU (central processing unit) has ROM (read-only memory) and RAM (write-read memory)
It operates according to programs and data (parameters, etc.) stored therein, and reads data and controls the drive unit. These CPU, ROM, and RAM constitute the control unit. Data from the denomination discrimination unit DNJ, dispensing control discrimination unit ABJ, conveyance state detection sensor KCH, dispensing detection sensor KCL, and withdrawal detection sensor KHT, and interface from the control unit CNG of the operation unit or separate tellers machine and cash dispensing machine. The data input via Face ITF is immediately taken into the RAM and sent to the banknote dispensing unit DCH, banknote transport unit CNV, and display unit.
Used for DSP control.

The banknote dispensing unit DCH includes a take-out mechanism 3 for taking out banknotes one by one from the cassette 2 and a sensor 12 for detecting banknotes one by one each time the banknotes are taken out.

The banknote transport unit CNV transports and temporarily holds the removed banknotes, and transports them to a payout port or to a reject unit, and includes transport mechanisms 4, 5, a transport body 6,
It includes a conveyor belt 8, a switching member 10, and a return path 11.

The display section DSP displays the number of coins thrown out, errors such as accidents, etc.

The conveyance pulse generator HPG generates pulses (conveyance pulses) in synchronization with the driving of the conveyance belt 8. Holes or slits are provided along the circumference of a disc attached to the drive shaft, and pulses are generated by detecting the holes or slits with a photocoupler or the like.

FIG. 4 is a diagram showing a part of the memory area in the RAM of FIG. 3.

The dispensed sheet number memories TS1 to TS3 store the number of sheets to be dispensed for each of the upper, middle, and lower cassettes. Length check upper limit memories LL1 to LL3 each store the upper limit number of pulses used for length checking for each cassette. Denomination setting memory DE1~
3 stores which denomination of banknotes is contained in each cassette. The dispensed number memory TSX stores data on the number of bills to be dispensed for the banknotes of the currently dispensed denomination. The dispensing counter TCOU counts the number of bills dispensed. Length abnormal value memory A sets the value of length upper limit memory LLX to allowable value α (α≒
20 mm: 20 pulses) is stored, and if the length check counter SCOU counts more than A = LL Note that this length check counter SCOU corresponds to a counting section. The payout conveyance value memory B is a reference value B=LLX+β (where β=
L-LLX, where L is equal to the sum of the distance between the payout detection sensor KCL and the payout port 9 and the length of the bill protruding from the payout port 9. ).

Further, the length upper limit memory LLX selects the length of the largest bill among the denominations of the dispensed bills from the length upper limit memories LL1 to LL3 and stores the data.
The dispensing check counter DCOU counts the conveyance pulses in order to cause the dispensing material to protrude from the dispensing port 9 by a predetermined length. In addition, the length check counter
SCOU counts the pulses (pulses from the transport pulse generator HPG) that are emitted to check the length of the banknotes sent to the payout port 9 in batches.

Next, the operation of the control system of the dispensing machine will be explained with reference to the flowchart shown in FIG.

When the dispensing process is started, a denomination discrimination process is first performed (102). Although the specific contents of this process are not shown, it consists of the following steps.
First, when the cassette 2 is loaded into the machine body 1, the denomination set by the select piece is determined based on which micro switch is turned on. That is, the combination of microswitches that are turned on among the three microswitches provided in each of the upper, middle, and lower rows is determined. Then, the set denomination determined in this way is stored in the denomination memory DE _o of the storage device.
(n=1 to 3). With this, the first stage ~
The determination and memorization of the denominations of cassettes 2, 2, 2 in the third row are completed.

The number of selection pieces 15, 15, . . . installed is three in the illustrated embodiment, but this number may be determined depending on the number of types of banknotes to be handled. In the example, we assume the mark of West Germany, 10 marks,
20 marks, 50 marks, 100 marks, 500 marks
There are three denominations, but in the case of Japan, the currently circulating banknotes are 1,000 yen, 1,000 yen,
Since there are 4 denominations of 5,000 yen and 10,000 yen, select pieces 15, 15, ... and micro switch 3 are available.
4, 34, . . . may also be two each.

In addition, in the illustrated example, the cassettes 2, 2 loaded into the machine body 1 are arranged in three stages, top, middle, and bottom, but the number of cassettes 2, 2 to be installed, such as four or five stages, can be selected as appropriate depending on the model. Yes, there is no limit to the number.

When the above denomination discrimination process (102) is completed, data indicating the denomination stored in each cassette is set in DE1-3 corresponding to each cassette. Next, a length upper limit value is set (104). That is,
According to the result of denomination discrimination (102), the upper limit of length is determined for each cassette for the denomination.
Read from ROM, maximum length memory in RAM LL
Write in numbers 1 to 3. As a result, an upper limit value for banknotes stored in each cassette is set corresponding to each cassette.

Next, check for near end and empty (106). Then, the number of sheets to be dispensed is determined from the outside (external operation unit or control unit CNS of Teller's Machine, etc.).
(108), and then sets the parameter n (110).

Next, the maximum value data of the length upper limit memories LL1 to LL3 for the denomination for which the number of coins to be dispensed is set is stored in the length upper limit memory LLX. Then, the value of LLX and the allowable value α are added and stored in the length abnormal value memory A, and the value of LLX and the allowable value β are added and stored in the payout conveyance value memory B (111).

Next, 1 is added to the parameter n (112), and it is determined whether or not the dispensed sheet number memory TS _o is 0 (114). Then, if the contents of _TSO are not 0, the contents of memory _TSO are set in the dispensed sheet number memory TSX (116).
Then, the banknotes are ejected from the n-th cassette (where n is 1, 2, or 3, n = 1 corresponds to the upper cassette, n = 2 corresponds to the middle cassette, and n = 3 corresponds to the lower cassette), but, The number of sheets is the number of sheets thrown out memory TSX
(118).

At step 114, the contents of the dispensed sheet number memory TS _o are 0.
If it is determined that n=3, it is determined (120), and if n≠3, the process returns to step 112. n
When =3, the dispensing operation is completed (122), and the banknotes are paid out at once from the temporary holding section 7 to the dispensing port 9 (124). This discharging is performed by rotating the conveyor belt 8 in the normal direction.

Next, it is determined whether the conveyance state detection sensor KCH is on or not (126), and when it is on, the length check counter SCOU counts the conveyance pulses from the conveyance pulse generator HPG (128).

Next, it is determined whether the value of the length check counter SCOU is greater than the value obtained in step 111, that is, the value of the length abnormal value memory A (130). Then, when SCOU>A, the stacking state has collapsed, so the conveyor belt 8 is stopped to stop conveying the banknotes (132), and the conveyor belt 8 is reversed for a predetermined period of time (134). As a result, the collapsed banknotes are returned to the front of the switching member 10.

Next, when the switching member 10 is turned on to set the state shown by the solid line in FIG. 1 (136) and the conveyor belt 8 is rotated forward for a predetermined period of time, the stacked banknotes are collected in the returned banknote storage section. (138). Then, the switching member 10 is turned off to be in the state indicated by the dotted line in FIG. 1 (140). Furthermore, it is determined whether or not re-throwing is necessary (142), and if necessary, the process returns to step 110, and if unnecessary, the operation is ended.

When SCOU≦A in step 130, that is, when the stacked state has not collapsed, it is determined whether the conveyance state detection sensor KCH is turned on (144). When KCH is on, the process returns to step 130, but when KCH is off, that is, when no bill is detected, the length check counter SCOU is set to 0.
Make it.

Next, it is determined whether or not the dispensing state detection sensor KCL is turned on (147), and when it is turned on, the dispensing check counter DCOU
Count the delivery pulses from the HPG (148).
This counting operation is repeated until the value of the counter DCOU becomes equal to the value of the payout conveyance value memory B (150). Then, when DCOU=B, the counter
The value of DCOU is set to 0 and transport is stopped (152).
At this time, the stacked banknotes should protrude from the payout port 9 by a predetermined length.

Next, it is determined whether or not the extraction detection sensor KHT has turned off (154), and if it has turned off, the operation is stopped because the banknote has been extracted by the teller. If the sensor KHT is not turned off, it is determined whether the payout detection sensor KCL is turned on (156), and if the sensor KCL is turned off, the process returns to step 154.

It is believed that when the sensor KCL was on, the teller pushed the banknotes protruding from the payout port 9 with his hand, causing the banknotes to be returned inside. Therefore, the value in the length upper limit memory is subtracted from the value in the dispensing conveyance value memory B (158), and the conveyor belt 8 is rotated in the normal direction to eject the bill again (160). Then, return to step 148.

Here, the characteristic functions of the dispensing machine according to the above embodiment can be summarized as follows.

That is, while the conveyance state detection sensor KCH is detecting banknotes, the conveyance pulses are counted (126, 128), and when a collapse of stacking is detected based on this count value (130), the switching member 1 is
0 is activated to collect the stacked banknotes into the storage section 2J (132, 140). Here, since the conveyance pulse is synchronized with the drive of the conveyor belt 8, the collapse of stacking can be detected without being affected by changes in conveyance speed due to wear of the belt system. By this,
Bills will no longer be dispensed from the dispensing port 9 with the piles collapsed.

It goes without saying that the present invention is not limited to the above-mentioned embodiments, and that various modifications can be made.

[Effect of idea]

As described above, in this invention, while detecting paper sheets that are conveyed in bulk from the temporary storage section to the dispensing port in a pile, the conveyance pulses synchronized with the drive of the conveyance belt system are counted, and the counted value is If it exceeds a standard value, it is assumed that there is an abnormal length due to collapse of the stack, and transport is prohibited and the paper sheets are collected.Therefore, there is no possibility that the paper sheets will be delivered without the stack being collapsed. do not have.
