DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper sheet conveying device. The banknote counting machine used in financial institutions, etc., counts the banknotes that pass through the transport path by feeding the banknotes one by one to the transport path, but the banknotes that were normally counted as the banknotes were not properly counted. To distinguish banknotes,
A switching gate is provided in the transport path to transport each bill.

[0002] When the banknote transport in the transport path is interrupted, the transport gate is switched in order to collect the banknote remaining in the transport path, and it is required to prevent the paper jam occurring at the switching gate portion from being jammed. .

[0003]

2. Description of the Related Art FIG. 5 is an explanatory view of a main part of a bill conveyance.
In FIG. 5A, bills 51 counted by a bill counter are displayed.
Are fed out one by one from the banknote supply unit 50 to the transport path 5,
Various sensors such as bill feeding sensor S1, skew sensor
S2, a longitudinal width detection sensor (detection of different denomination bills) S3, a bill thickness detection sensor S4, and the like are detected, and these detection information is notified to a transport monitoring unit (not shown) to monitor the transport status of the bills.

That is, the transport monitoring unit determines whether or not the bill 51 is a normal bill based on the notified detection information. In the case of a normal bill, the bill 51 is conveyed toward the normal bill pool unit 52, and the bill 51 is stored in the normal bill pool unit 52 after being counted by the number counting sensor S5.

If an abnormality in the bill 51 itself is detected during the transportation, the transportation monitoring unit sets the gate 59 to the normal bill pool 52.
To the rejected bill pool 53. This gate switching is performed when the gate timing sensor S9 detects the conveyed bill 51, as shown in FIG. Start up, switch the transport to reject bill pool 53, and reject bill pool
The bill 51 is collected in 53.

When the bill 51 collected in the reject bill pool 53 is detected by the reject counting sensor S6, the gate 59 of the gate switching section 56 closes the gate and returns the transport path 5 to the transport of the normal bill.

The banknote 51 conveyed as described above is switched between normal conveyance to the normal banknote pool section 52 and conveyance to the reject banknote pool section 53 by switching of the gate switching section 56. If a processing or transport abnormality occurs, supply of the bill 51 from the bill supply unit 50 is interrupted, and the gate
If 59 is open, the banknotes that close the gate 59 and remain in the transport path 5 are transported toward the normal banknote pool 52 and are collected.

[0008]

As described above, the transport path 5
When the banknotes staying in the banknotes are conveyed toward the normal banknote pool section 52 and collected, the gate 59 is closed if the gate 59 is open. When the banknote 51-1 is skewed and stays as shown in FIG. 7A, a part of the banknote 51-1 is pushed down to the reject banknote pool 53 by the gate 59, and the medium is transported. 6 and the gate 59 (FIG. 6 (b)), a paper jam occurs in which the paper cannot be discharged in the medium discharge direction.

An object of the present invention is to prevent a paper jam from occurring.

[0010]

FIG. 1 is a block diagram showing the principle of the present invention. What is claimed is: 1. A sheet transport device for switching a transport gate of a sheet based on sensor information for detecting the sheet transported on the transport path, comprising: a transport path 1; and a medium detection unit provided in the transport path 1. 2 and a transport control unit 3 for transporting paper sheets
And a gate switching control unit 4 for switching the conveyance of the sheets conveyed through the conveyance path 1 based on the detection information of the medium detection unit 2. Upon receiving the command, the conveyance of the paper sheets remaining in the conveyance path 1 is started and notified to the gate switching control unit 4, and the gate switching control unit 4
The detection information of the paper sheet detected by the medium detection unit 2 is checked, and when the detection of the paper sheet is lost, the gate is switched so that the paper sheet is taken into a predetermined stacking unit.

[0011]

The gate switching control section checks the detection information of the paper sheet detected by the medium detection section, and switches the gate so that the paper sheet is taken into a predetermined stacking section when the detection of the paper sheet disappears. I do.

[0012]

FIG. 2 shows a system configuration diagram of the embodiment. FIG.
Shows a transport device that is transported to count bills, the transport device, the bill supply unit 50, the transport path 1 having the detection sensor 21 and the gate 41, among the transported bills,
A stacking unit 12 for taking in normally counted bills, and a stacking unit 13 for taking in bills that are rejected when an abnormality is detected in the bills
Operation information input unit 32 having a drive unit 31 and an ejection key 33
And a processing device 30 having a transport control unit 3, a gate switching control unit 4, and a sensor information collection processing unit 35.

The bills to be counted are fed out one by one from the bill supply unit 50 to the transport path as shown in FIG. The bills being conveyed are detected by various sensors, that is, bill feeding sensor S1, skew sensor S2, longitudinal width detection sensor (detection of different kinds of bills) S3, bill thickness detection sensor S4, and the like. This is notified to the sensor information collection processing unit 35 (FIG. 2) in FIG.

The sensor information collection processing unit 35 sorts out whether the bill is normal or not based on the notified detection information. If an abnormal bill is detected, the gate drive timing sensor operates and the gate switching control unit 4 Integrated gate 41
Switching from transport of banknotes to 12 to stacking unit 13.

If an abnormal condition arises in which the operation of the apparatus must be stopped during the transfer of the banknote, the transfer control section 3 issues a transfer stop command to the drive section 31 to stop the operation of the apparatus. At this time, a plurality of bills remain in the transport path 1. In order to discharge these remaining bills out of the transport path 1, a discharge command is issued to the transport control unit 3 by pressing the discharge key 33 of the operation information input unit 32.

The gate switching process at the time of discharging the remaining bill will be described with reference to the explanatory diagram of the gate switching according to the embodiment of FIG. 3 and the processing procedure of the transport path switching of FIG. In FIG. 4, when a discharge command is issued to the transport control unit 3, the transport control unit 3 issues a transport start notification to the drive unit 31 and issues a medium discharge command to the gate switching control unit 4 in processing step 80.

In the processing step 81, the drive unit 31
The transport of the transport section 1 is started by rotating 14 (FIG. 3). When the conveyance of the conveyance path 1 is started, if the gate 41 is opened toward the stacking unit 12 as shown in FIG. 3A, the gate switching control unit 4 does not perform the gate switching process. The bills 51 remaining in the transport path are transported to the stacking unit 12 and collected.

On the other hand, as shown in FIG. 3B, when the gate 41 is open toward the collecting section 13, the gate 41 in the transport path 1
If there is a banknote 51 that has not passed through the banknote, the detection sensor 21 is detecting the banknote 51 or the detection sensor 21
It should detect 51.

That is, in the processing step 82, the gate switching control section 4 checks the detection information of the bill 51 detected by the detection sensor 21. If the bill medium is being detected (detection = 11), the process waits for the passage of the bill 51 through the detection sensor 21 (at the time when the sensor is switched from on to off) in processing step 83.

When the bill 51 passes through the detection sensor 21, the gate switching control section 4 waits for a predetermined time (gate passage time = T) to elapse (processing step 84).
13). This gate passage time "T"
Is, for example, a bill 51 being conveyed in FIG.
Is set in advance as the time required for transport from the transport position P1 where the leading end of the bill 51 is detected by the detection sensor 21 to the transport position P2 that has passed through the gate 41.

When time "T" has elapsed, processing step 85
Then, the gate switching control unit 4 checks the detection information from the detection sensor 21, and if the detection information is “detection = 11”, returns to the processing step 83 and waits again for the bill 51 to pass through the detection sensor.

If the detection information does not indicate that a bill medium is being detected (detection = 00), the gate switching control unit 4
Closes the gate 41 and closes the transfer to the accumulation unit 13. As a result of checking the detection information in processing step 82,
If the detection information is “detection = 00”, the process proceeds to processing step 84 in order to discharge the residual medium conveyed to the gate 41 to the stacking unit 13 within a predetermined time.

[0023]

As described above, when discharging the remaining banknotes in the transport path when the gate 41 of the transport path is open, it is confirmed based on the detection information of the detection sensor 21 that there is no bill near the gate 41. By performing the gate switching after this, the occurrence of the jam state of the bill can be prevented.
