Abstract

PURPOSE:To carry out a feeding process without making the device inoperative, by providing a control means for driving a feeding roller again after once stopping the feeding roller according to a predetermined output from an abnormality detecting means. CONSTITUTION:When CPU 30 determines a skew bill in receipt of an output from a skew sensor 23, CPU 30 controls to switch a flapper 20 to recover the skew bill through a feed channel 22 to a bill recovery box 21. thereafter, CPU 30 controls to restore the flapper 20 to an original position. In the next step, CPU 30 switches off a clutch 10 to once stop the rotation of a feeding roller 3. When the roller 3 is stopped, a friction roller 4 is rotated at a small angle in an anti-feeding direction. Accordingly, a contact position of the friction roller 4 with respect to the feeding roller 3 is displaced, thereby removing a dust present between both the rollers 3 and 4. Thus, a portion of the roller 3 not injured and worn comes into contact with the roller 4, and it is therefore possible to prevent the generation of continuous skew.

Embodiment of the Invention An embodiment of the invention will be described below in detail with reference to the drawings.

The drawing shows a bill dispensing device, and in FIG. 1, a bill cartridge 1 has a dispensing roller 3 and a friction roller 4 disposed opposite to the roller 3 on the front end dispensing side of a horizontally suspended pedestal 2. In addition, a pressing plate 5 is provided that presses and urges the bill A on the pedestal 2 toward the feeding side, and when the above-mentioned feeding roller 3 is driven in the counterclockwise direction, the feeding section 6 between the above-mentioned rollers 3 and 4 is provided. Paper money A from the guide 7.8 to the feeding port 9
It is configured to output one sheet in sequence.

Here, the above-mentioned feeding roller 3 is connected to an 0-ra shaft 11 via a clutch 10, and a motor 1 is connected to this roller shaft 11.
2 are connected.

In addition, an auxiliary roller @1 is diagonally above the roller shaft 11 mentioned above.
3 is mounted horizontally, and the feeding roller 3 is mounted on this auxiliary roller shaft 13.
An auxiliary feeding roller 14 that rotates in conjunction with this is fitted.

As is clear from FIG.
The driving pulley 15 is fitted to the auxiliary roller shaft 13, and the driven pulley 16 is fitted to the auxiliary roller shaft 13.
, 16 with a belt 17 stretched between them.

Further, the ffm roller 4, which is disposed opposite to the above-mentioned feeding roller 3, is configured to rotate the roller 4 in a counter-feeding direction (counterclockwise direction in FIG. 1).
A one-sided clutch 4a is interposed to allow rotation only when the feed roller 3 is stopped, and the friction roller 4 is configured to rotate counterclockwise by a small angle when the feed roller 3 is stopped.

By the way, the above-mentioned feed-out port 9 and bill payment discharge port 18
A flapper 2 is installed at the branch part of the first conveyance path 19 connecting the
0, and also forms a 211th feeding path 22 for collecting abnormal banknotes that connects the above-mentioned branch part and the banknote collection box 21.

A skew detection sensor 2 for detecting skewed banknotes is provided on the first conveyance path 19 in front of the above-mentioned flapper 20.
3 is arranged, and the first conveyance path 1 at the rear of the flapper 20
9 is provided with a counting sensor 24 for detecting the number of bills to be dispensed. Both of these sensors 23 and 24 are constituted by, for example, photoelectric sensors equipped with a light-emitting element and a light-receiving element.

FIG. 2 shows a control circuit of the feeding device, in which the CPU 30 controls the clutch 10. The RAM 26 drives and controls the T-12 and the flapper 20, and stores necessary data such as the number of bills A to be paid in response to customer transactions.

Here, the CPU 30 described above has a built-in counter, and the number of allowed skews is preset to, for example, three times.

In addition, the predetermined output of the skew detection sensor 23 (the skew is
The above-mentioned CPU 30 performs temporary stop and re-drive control of the feeding roller 3 based on the output output when the rotation is detected.

The operation of the feeding device configured as described above will be explained with reference to the flowchart shown in FIG.

In a first step 31, the CPU 30 drives and controls the motor 12 based on input signals from a payment operation input section (not shown) and turns on the clutch 10.

When the clutch 10 described above is turned ON, the rotational force of the motor 12 is transmitted to the roller shaft 11 via the clutch 10, and the rotation of the feeding roller 53 and the auxiliary feeding roller 14 is controlled in the counterclockwise direction in FIG. Feeding roller 3 and am
The banknotes A are sequentially dispensed one by one from the dispensing unit 6 with the row 54.

Next, in a second step 32, the CPU 30 determines whether the banknote is a skewed banknote or a normal banknote based on the presence or absence of a skew detection output from the skew detection sensor '+23. 3 steps 3
Move to 3.

In this third step 33, the CPtJ 30 resets the built-in counter (a counter that counts the number of allowed skews) to make the count value zero, and then proceeds to the next fourth step 34.
to move to.

In this fourth step 34, the CPU 30
It is determined whether a predetermined number of bills corresponding to the payment has been dispensed based on the dispensed bill number signal from the dispenser, and if the predetermined number is not reached, the process returns to the first step 31, and when the predetermined number of bills has been dispensed, a series of normal dispensing processes are performed. finish.

Note that the banknotes dispensed from the above-mentioned dispensing port 9 are sequentially discharged to the dispensing port 18 via the upper side of the flapper 20, which is switched to the solid line state in FIG. 1, and the first conveyance path 19.

By the way, when the CPU 30 determines in the second step 32 that the banknote is a skewed banknote based on the skew detection output from the skew detection sensor 23, the process proceeds to the next fifth step 35.

In this fifth step 35, the CPLJ 30 increments the built-in counter by 1 to make the count value 1, and then proceeds to the next sixth step 36.

In this sixth step 36, the CPU 30 controls the flapper 20 to switch to the imaginary line position shown in FIG.
After the banknotes are collected into the banknote collection box 21 via the conveyance path 22, the flapper 20 is controlled to return to its original position as shown by the solid line in FIG.

Next, in a seventh step 37, the CPLJ 30 determines whether the built-in counter has counted up.

At this stage when the count value of the above-mentioned built-in counter is 1, the built-in counter has not counted up, so the process returns to the first step 31.

Due to the skewed banknotes similar to those described above, the count value of the built-in counter becomes 3, and when this built-in counter counts up, the process moves to the next eighth step 38.

In this eighth step 38, the CPU 30 turns off the clutch 10 to temporarily stop the rotation of the feeding row 53.

When the above-mentioned feed-out row 53 stops, the friction roller 4, which is disposed opposite to this roller 3, rotates by a small angle in the counter-feed-out direction, that is, in the counterclockwise direction in FIG. 1, due to the reaction of the stop.

For this reason, the position of the friction roller 4 in contact with the feed-out roller 3 is displaced, so that the above-mentioned dust between the rollers 3 and 4 is removed, and the portion of the friction roller 4 that is not damaged or worn is removed from the feed-out roller 4. Since the contact point is in contact with the contact point, it is possible to prevent the skew phenomenon from occurring continuously.

After the clutch 10 is turned off in the eighth step 38, the process returns to the first step 31, and the CPtJ 30 turns on the clutch 10 again and re-drives the feeding roller 4, so that the number of bills A corresponding to the payment is dispensed. are fed out in sequence and normally, and as a result, there is an effect that the feeding process can be performed without causing the device to go down.

Regarding the correspondence between the structure of this invention and the above-mentioned embodiments, the paper sheet cartridge of this invention corresponds to the banknote cartridge 1 of the embodiment, and similarly, the paper sheet corresponds to banknote A. Although the paper sheet corresponds to a skewed banknote, the feeding path corresponds to the first conveyance path 19, the detection means corresponds to the skew detection sensor 23, and the control means corresponds to the CPLI 30, the present invention does not differ from the above embodiment. It is not limited to only the configuration.

Furthermore, in the above embodiment, the skew detection sensor 23
is a predetermined output that detects skewed banknotes three times, in other words
Although the feed roller 3 is configured to be temporarily stopped or driven again when the count value of the counter built in the PU 30 reaches 3, the above-mentioned count value is not limited to 3.
