Abstract

PROBLEM TO BE SOLVED: To stop the operation of a machine when there is a large possibility that a paper jam occurs. SOLUTION: When a delivery request is given (S101), bank note conveyance to a lump delivery retention section is instructed (S102), and prescribed bills are accumulated in the lump delivery retention section. When the prescribed number of bills are made ready, a bank note conveyance start to a delivery port is instructed (S103). Bank notes are delivered in a lump when a lump delivery motor is driven and a lump delivery belt is traveled. The load current value of the lump delivery motor is detected and compared with the prescribed motor load current value set in advance for judgment (S104). If the load current value of the lump delivery motor is smaller than the predetermined value, it indicates that bills are satisfactorily conveyed, thus lump delivery is continues (S105), and a delivery operation is completed (S106). If the load current value of the lump delivery motor exceeds the predetermined value, it is judged that there is a large probability to cause a paper jam during the delivery operation, and the delivery operation is stopped (S107).

And send it out.

Although not shown, a separation roller and a separation claw are provided near the entrance of the 1,000 yen safe 41, and
, One by one, is surely fed into the low bill transport path 12.

Next, the operation of receiving and paying out the bill A will be briefly described.

First, when a 1,000-yen bill (banknote A) is inserted into the banknote insertion slot 8, the banknote A is identified by the banknote identification section 4,
The paper is fed from the receiving conveyance path 10 through the first gate 14 (switching the gate in this case) to the low bill storage section 6 through the low bill conveyance path 12. The bill A sent to the low bill storage unit 6 is sent from the storage standby position connected to the low bill transport path 12 to the 1,000 yen safe 41 by the feed stack plate.

On the other hand, when a 5,000-yen bill or a 10,000-yen bill (banknote A) is inserted into the bill insertion slot 8, the bill identification unit 4 determines that the bill is a 5,000-yen bill or a 10,000-yen bill. The identification is recognized, the first gate 14 rotates, and the transport path is switched, and is sent from the receiving transport path 10 to the high-value banknote storage unit 3 through the high-value banknote transport path 11.

In the high bill storage unit 3, the high bill stacking plate 25 is at the upper end position and is in a standby state for receiving a 10,000-yen bill. In this state, the large bill stacking plate 25 moves down from this state, and sends the bill A to the 10,000 yen safe 24.

When the banknote A is identified as a 5,000-yen bill by the banknote recognition section 4, the high-amount banknote stack plate 25 moves to the lower end position before the banknote A is fed into the standby passage 21. When the banknote A is received in the standby passage 21, the high-value banknote stack plate 25 moves upward and sends the banknote A to the 5,000 yen safe 23.

Next, in the case of dispensing bills, the second gate 15 is rotated to connect the low bill transporting path 12 and the payout transporting path 13 and the low bill transport belt 32 travels, and the bill is paid for 1,000 yen. Banknote A is transferred from the safe 41 to the low-value banknote transport path 1
2 and the dispensing transport path 13, the bill dispensing section 5
Are sent one by one. The banknotes A are counted by the second passage sensor 38 while the bills are
They are accumulated as if they are stacked on top of each other.

When the number of bills A in the batch payout holding section 35 reaches a predetermined number, the low bill transport belt 32 stops, and at the same time, the guide plate 33 of the bill payout section 5 moves upward, and the guide plate 33 accompanies the bills A. When it reaches the upper end position, the collective payout belt 34 is driven by the collective payout motor 39.
Starts running, and sends out the banknotes A from the batch payout holding unit 35 to the banknote payout port 9 collectively.

On the other hand, when the identification sensor 40 identifies that the banknotes A are being conveyed in an overlapping manner in the transport process from the 1,000 yen safe 41 to the collective dispensing and holding section 35, the overlapping banknotes A are collectively dispensed and held. Waiting to reach the unit 35, the transport of the banknote A from the 1,000 yen safe 41 is temporarily stopped, the guide plate 33 is moved up, and then the reject stack plate 37 is moved down. Banknote A
Is sent into the reject holding unit 36. Then, a predetermined number of banknotes A are newly conveyed in the same procedure as described above.

Although the overall structure of the paper sheet processing machine is as described above, the gist of the present invention relates to an improvement particularly relating to a bill payout mechanism.

As described above, the payout mechanism of the present sheet processing apparatus drives a motor (not shown) to drive the low bill transport belt 3 when there is a payout request (command).
2, the banknotes A are sent one by one from the thousand yen safe 41 to the banknote payout section 5 through the low-value banknote transport path 12 and the payout transport path 13.

The bills A are accumulated while being counted by the second passage sensor 38 so as to be stacked in the lump-sum payout holding section 35. When the number of banknotes A in the lump-sum payment holding unit 35 reaches a predetermined number, the low-amount banknote transport belt 32 is stopped, and the lump-sum payout motor 39 is driven to move the lump-sum payout belt 34 so that the lump-sum bills A are collectively collected. It is sent from the lump-sum payment holding section 35 to the bill payout port 9.

At this time, the present invention has a function of detecting the jam of banknotes during the lump-out operation, stopping the operation of the machine, and preventing troubles thereafter. The functions are realized by configuring respective function realizing means by the control microcomputer 7 to be described later and each control device connected thereto.

The operation flow of the function realizing means for detecting the jam of the bill will be described with reference to the flowchart of FIG.

First, when there is a payout request (S10
1) In step S102, a command is issued to transfer the banknotes to the lump-sum payment holding unit. That is, predetermined banknotes are accumulated in the lump-sum payment holding unit 35 by the low-value banknote transport belt 32 or the like driven by a motor (not shown). In a state where the predetermined number of banknotes have been collected, the process proceeds to step S103, and a batch payment, that is, a command to convey the banknotes to the payout port 9 is instructed.

This is performed by driving the collective payout motor 39 and running the collective payout belt 34. At this time, the load current value of the collective payout motor 39 that drives the collective payout belt 34 is detected, and a comparison is made with a predetermined motor load current value set in advance in step S104.

If the load current value of the collective payout motor 39 is smaller than a predetermined set value, banknotes are conveyed satisfactorily. Therefore, collective payout is performed as it is and transfer to the payout port 9 is performed. Then, the payout operation ends (S106).

On the other hand, if the load current value of the batch payout motor 39 exceeds the predetermined set value in step S104, the flow advances to step S107 to stop the payout operation.

This is because the state of the banknotes A accumulated in the lump-sum payment holding unit 35, that is, the state of the banknotes A themselves and the state of the alignment of the banknotes A, is not smooth. There is a high probability that a paper jam will occur during the payout operation. At that time, the load of the collective payout motor 39 driving the collective payout belt 34 is increased.

In this stopped state, since the lump-out operation has just started with the lump-out payout belt 34, the bills A to be paid out still exist in the lump-out payout belt 34, and at least one of the bills 9 is dispensed. , The banknote A to be paid out becomes clear if the machine is opened in that state, so that there is no trouble in delivery to the user.

A control circuit for performing the operation of the sheet processing apparatus of the present invention will be described with reference to the block diagram of FIG.

The sheet processing apparatus is controlled by a control microcomputer 7, and the control microcomputer 7 stores a control program for controlling the entire machine.
M74 is connected thereto, and an internal memory (RAM) 73 for storing a detection signal such as a determination operation during the operation is connected.

The bill payout motor 71 and the collective payout motor 39 are connected to the payout mechanism according to the gist of the present invention.
Nine current detection circuits 72 are connected. Note that control elements for controlling the entire machine are omitted in this figure.
