Description

TECHNICAL FIELD The present invention relates to a paper sheet discriminating and storing device.

[Conventional technology]

Conventionally, a paper sheet identifying and storing device for identifying and storing two types of paper sheets has a storage box for each paper sheet. In the case of such a configuration, when one storage box reaches the specified amount and becomes full, one type of paper sheet cannot be stored. For example, in an automatic vending machine or another unmanned sales system, Even if the other storage box has a sufficient storage capacity, the paper sheet identification storage device must stop the storage. Even if a particular paper sheet is stored more than other paper sheets and becomes full, if other paper sheets are used, it is possible to purchase products by vending machines, etc. Since all the paper sheets are unusable, it has caused great inconvenience to both the selling side and the purchasing side.

In order to solve this, one storage is provided with a pair of partition plates that have holes on the surfaces facing each other and are urged toward the holes facing each other inside and away from each other. A paper sheet identifying and storing device provided with a box has been proposed (for example, Japanese Utility Model Laid-Open No. 60-673). In this proposed paper sheet identifying and storing device, the paper sheet inserted through the insertion port is identified by the identifying means, and the inserted paper sheet is sorted by the sorting mechanism based on the determination result by the identifying means. Is transferred to either one of a pair of receiving devices provided so as to face the hole of the. When the paper sheet is received by the receiving device, the pushing member is reciprocated to push the paper sheet into the storage box through the hole. Further, the rear surface of the partition plate is provided with detection means for detecting that the storage of the paper sheets is the limit when the distance between them reaches a predetermined dimension. As a result, the storage space in one storage box can be flexibly shared by the two types of paper sheets, so that storage and sale can be performed more efficiently than when two storage boxes are provided separately.

[Problems to be solved by the invention]

However, in the paper sheet identification and storage device provided with the above-mentioned one storage box, a sorting mechanism for sorting the paper sheets and a device for driving the same are required, and the device becomes large.

It detects that it is in the storage position and outputs a second storage position detection signal. The control device 112 is composed of a microcomputer, and as its functional means, a counting unit 114 and a determination unit 116.
And a drive control unit 118. The counting unit 114 is a passage detector 28
The passage detection pulses from are counted. The determination unit 116 is the counting unit 1
When the count value of 14 reaches a predetermined storage limit value for paper sheets, a storage limit reaching signal is output to the drive control unit 118 and the display device 120. The drive control unit 118 outputs a signal from the identification device 30 indicating whether the paper sheet is proper or not, and a signal indicating the type of the paper sheet (first paper sheet or second paper sheet) when it is proper. , The insertion detection signal and the ejection detection signal from the insertion detector 106, the first storage position detection signal from the first storage position detector 108, and the second storage position detection signal from the second storage position detector 110. Based on these signals, the drive of the transport drive device 122 and the storage box drive device 72 is controlled.

FIG. 6 is a flow chart showing an example of the operation of the control device 112 shown in FIG. The operation will be described below with reference to FIGS. 1 to 6.

First, when the power (not shown) of this device is turned on, the storage box
"Φ" is initially set as the storage amount C of the paper sheets stored in 40 (step 201). It is assumed that the program has a built-in storage limit value Cmax of paper sheets that can be stored in the storage box 40 in advance. In this state, when a paper sheet is inserted through the insertion port 12, the insertion detector 106 sends an insertion detection signal to the drive control unit 118 (YES in step 202).
When the drive control unit 118 receives the insertion detection signal, the transport drive unit 122 moves the belt 22 in the direction of arrow F ₁ (step 203). At this time, the belt 84 is also moved in the arrow F ₂ direction. As a result, the inserted paper sheets are nipped by the belt 22 and the rollers 24, 26, and are conveyed to the first conveyance path 50 side. At this time, the leading edge of the paper sheet first passes through the passage detector 28 and then the identification device 30. The identification device 30 first determines whether or not the passing paper sheets are proper (step 204),
If it is improper, an improper signal is sent to the drive control unit 118, and if it is improper, an appropriate signal is sent to the drive control unit 118.

When the drive control unit 118 receives the improper signal (step 204)
No.) and the belt 22 by the transport driving device 122 is moved in the direction of arrow B (step 205), and the ejection detection signal from the insertion detector 106 is received (YES in step 204), the transport driving device 122 is driven. It stops (step 207, and waits for the insertion of the next paper sheet) (step 202).

On the other hand, the drive control unit 118 receives the appropriate signal (step 2
When YES of 04), the conveyance drive device 122 continues to convey the paper sheet in the direction of the arrow F ₁ , and when the trailing edge of the paper sheet passes the passage detector 28, the passage detector 28 drives and controls the passage detection pulse. It is sent to the section 118 (YES in step 208). Upon receiving the passage detection pulse, the counting unit 114 increments the stored amount C and sends the stored amount C to the determination unit 116 (step 209). The determination unit 116 compares the received storage amount C with a predetermined storage limit value Cmax (step 210), and when the storage amount C is larger than the storage limit value Cmax (C> Cmax) (Y in step 210).
ES), the storage limit reaching signal is sent to the drive control unit 118 and the display unit 120.
Send to. When the display device 120 receives the storage limit signal, it indicates that the paper sheet cannot be stored any more (step
211). Further, when the drive control unit 118 receives the storage limit reaching signal, it moves to step 205 and returns the inserted paper sheets.

On the other hand, when the storage amount C is less than or equal to the storage limit value Cmax (C ≦ Cmax) (NO in step 210), the identification device 30 determines the type of paper sheet (step 212). The determination result (first paper sheet or second paper sheet) is sent to the drive control unit 118.

Next, the operation when the drive control unit 118 receives from the identification device 30 the fact that it is the first paper sheet will be described.

The paper sheet is conveyed through the first conveyance path 50 by the conveyance driving device 122, and when the trailing edge reaches the first storage position detector 108, the first storage position detector 108 drives the first storage position detection signal. It is sent to the control unit 118 (YES in step 213).
When the drive control unit 118 receives the first storage position detection signal,
Since the fact that the paper sheet conveyed from the identification device 30 is the first paper sheet has already been received, the driving of the conveyance drive device 122 is stopped (step 214). Next, the drive control unit 118
Sends a drive signal to the storage box drive device 72 to rotate the crank pulley 303 by the storage box drive motor 301. Here, the pin 70 formed on the upper surface of the crank pulley 303 rotates eccentrically on the upper surface of the crank pulley 303 (1/4 rotation in the counterclockwise direction in FIG. 1) so that the pin 70 extends in the longitudinal direction in the protruding groove 74. The entire storage box 40 is slid in the direction of arrow L while sliding to (step 215). At this time, the paper sheets stopped in the first transport passage 50, that is, the first paper sheet
The paper sheets pass through the rib 46 and are stored in the first paper sheet storage unit 60. When the crank pulley 303 further rotates counterclockwise by 1/4 and the storage operation of the first paper sheet is completed, the drive control unit 118 stops the drive of the storage box drive device 72, and the next paper sheet is moved. Wait for insertion (step 202).

Next, the operation when the drive control unit 118 receives the fact that it is the second paper sheet from the identification device 30 will be described.

Although the drive control unit 118 receives the first storage position detection signal as described above, since it has already received the fact that the paper sheet conveyed from the identification device 30 is the second paper sheet, the conveyance drive device Continue driving 122. Therefore, the paper sheet, that is, the second paper sheet, passes through the first transport passage 50 and the connection passage 10
It is guided to the second transfer passage 52 via 2. After that, the paper sheets are transported in the second transport path 52, and when the trailing edge reaches the second storage position detector 110, the second storage position detector 1
10 sends the second storage position detection signal to the drive control unit 118 (YES in step 216). Upon receiving the second storage position detection signal, the drive control unit 118 stops driving the transport drive device 122 (step 217). Next, the drive control unit 118 sends a drive signal to the storage box drive device 72 and causes the storage box drive motor 302 to rotate the crank pulley 303. Here, the pin 70 formed on the upper surface of the crank pulley 303 is eccentrically rotated on the upper surface of the crank pulley 303 (clockwise 1/4 rotation in FIG. 1) to move the pin 70 in the longitudinal direction in the protruding groove 74. While sliding, the entire storage box 40 is slid in the direction of arrow R (step 218). At this time, the second paper sheet stopped in the second transport passage 52 gets over the rib 48 and is stored in the second paper sheet storage portion 62. The crank pulley 303
When the second paper sheet storage operation is completed by further rotating clockwise by 1/4, the drive controller 118 stops driving the storage box drive device 72 and waits for the next paper sheet to be inserted (step 20
2).

Further, the newly inserted paper sheet is inserted through the insertion opening 12, and the newly inserted paper sheet is sandwiched between the belt 22 and the pulleys 24 and 26, and the first paper sheet is inserted.
When the leading edge approaches the entrance of the transport passage, the stored first paper sheets that have been discriminated and stored in the first paper sheet storage unit are held by the ribs 46 in the first paper sheet storage unit. The newly inserted paper sheet is guided into the first transport path without the newly inserted paper sheet and the stored first paper sheet interfering with each other.
Similarly, the newly inserted paper sheet is used as the second sheet by the identification device 30.
Even when the newly inserted paper sheet is identified as a paper sheet, when the newly inserted paper sheet passes through the first transport passage and the connection passage 102 and is guided into the second transport passage, it is identified and stored in the second paper sheet storage unit. Since the stored second paper sheet is held in the second paper sheet storage section by the rib 48 second paper sheet, the newly inserted paper sheet and the front edge of the stored second paper sheet interfere with each other. Without doing so, the newly inserted paper sheets are guided into the second transport passage. Further, the first paper sheet storage section is provided with a pulley 18 for pressing the paper sheet inward of the storage box by the spring property of the spring metal fitting, so that the first paper sheet storage section can store the first paper sheet in the storage box. By pushing inward the storage box, floating of the paper sheets can be prevented, and the effect of preventing the interference between the front edge of the newly inserted paper sheet and the first stored paper sheet can be further enhanced.

According to the above configuration, since the storage box is slid when the paper sheets are stored in the storage box, only one drive device is required to perform the storage operation. Further, since the pair of transport passages are connected by the connecting passage, a complicated sorting mechanism as in the conventional case is not required. Further, the storage limit of the paper sheets in the storage box can be determined by a simple configuration in which the passage of the paper sheets is detected and the passage detection pulse is counted.

〔The invention's effect〕

As is clear from the above description, according to the present invention, the pair of transport passages are connected by the connection passage, and the paper sheets are distributed by changing the stop position according to the type of the paper sheets. It is possible to provide a small-sized and inexpensive paper sheet identification / accommodation device with a simple structure that does not require a distribution mechanism having a complicated configuration as in the past.
