Description

DETAILED DESCRIPTION OF THE INVENTION (A) Technical Field to which the Invention pertains This invention relates to a main payout roller for a banknote stored in a banknote storage unit inside a machine, such as an automatic teller machine used for banking business. The present invention also relates to a method for controlling the feeding of sheets by a device for feeding by rotation of an auxiliary feeding roller.

(B) Conventional technology Generally, as shown in FIG. 5, a bill feeding mechanism has a main feeding roller 43 and an auxiliary feeding roller 44 immediately above the main feeding roller 43 in a feeding section 42 of a banknote storage section 41. The separating roller 45 is applied to the feeding roller 43, and the rotational force is input to the main feeding roller 43 and the auxiliary feeding roller 44 via the respective clutches, and the main feeding is performed one by one from the frontmost banknote of the banknote storage unit 41. It is fed out between the roller 43 and the separation roller 44, and this is detected by the sensor 46.

Referring to the timing chart of FIG. 6, the conventional control method will be described in more detail. The main feed roller 43 (FIG. 6A) is turned on by a feed command, and the main feed roller 43 is turned on.
While the rubber portion 43a is in contact with the frontmost banknote 47 and rotates several tens of degrees (in other words, while the feeding force acts on the frontmost banknote 47 by the frictional force of the rubber portion 43a), the auxiliary feeding roller 44 (the sixth
(B) is turned on to feed the front bills 47 in an auxiliary manner and pay out one bill at a time.

In addition, when the bills are fed out in a partially overlapped state (when the take-out occurs), the fact that the light shielding time of the sensor 46 is long is used to determine this as “take-out”,
After a certain period of time, the feeding is stopped and the taken-out banknotes are collected.

However, in the conventional control method, when the take-out occurs, the main feeding roller 43 is stopped before the second and subsequent bills are completely fed from the feeding unit 42, and as a result, the sensor 46 is shielded from light. There is a problem that the operation may be continued as it is, leading to a stop of the operation of the apparatus (apparatus down).

(C) Problems to be Solved by the Invention The present invention prevents the operation of the apparatus from being stopped (device down) by completely feeding out the second and subsequent sheets from the feeding section when the take-out occurs. It is possible,
In addition, it is an object of the present invention to provide a sheet feeding control method capable of restarting the feeding operation after collecting taken-out sheets at a predetermined place and completing feeding of a predetermined number of sheets.

(D) Means for Solving the Problems The present invention arranges a main feeding roller and an auxiliary feeding roller in a feeding section of a paper sheet storage unit, and detects both the fed paper sheets by a sensor and detects both rollers. In the device that controls the turning on and off of the rotation of the auxiliary feeding roller at the time of detecting the take-out of the sheet by the sensor, after rotating the main feeding roller until the taken-out sheet is completely fed, The method is a sheet feeding control method in which the rotation of the main feeding roller is stopped until the taken-out sheet is collected at a predetermined place, and the feeding operation is resumed after the collection.

(E) According to the present invention, when the sensor detects the take-out of the paper sheet, the main feeding roller continues to rotate, and the second and subsequent sheets in the taken-out state are completely removed from the feeding section. At the same time as the paper is fed, the auxiliary feeding roller stops the rotation and stops the feeding of the sheet after that, so that the sensor is connected to the main feeding roller portion in a state where the sensor is shielded from light, and the sheet does not remain.

Moreover, after the main feeding roller rotates until the take-out sheet is completely fed, the rotation of the main feeding roller is stopped until the take-out sheet is collected at a predetermined place. After the collection, the feeding operation is restarted.

(F) Effects of the Invention Therefore, according to the present invention, the paper sheets fed in a continuous state can be completely collected, and the sensor does not continue to be shielded from light. Reliability can be improved. In addition, since the next sheet is in a normal state in the sheet storage unit, after the above-mentioned taken-out sheet is collected at a predetermined place, the next feeding operation can be immediately restarted, and the feeding stop time is reduced. Can be minimized and a smooth restart can be performed.

(G) Embodiment One embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 shows a banknote depositing / dispensing mechanism to which the method of the present invention is applied.
The cartridge 2 is provided with a pressing plate 3 which moves up and down, and the bills 4 are deposited and stored on the pressing plate 3.

On the left side of the upper part of the cartridge 2 is a bill inlet 5, and bills passing through the passage 6 between the guide plates 6a, 6b are sent to the carry inlet 5 by receiving the pinching and conveying force between the stacking roller 7 and the conveying roller 8, and The push plate 3 is knocked down by the car 9 and
Integrated on top.

The right side of the upper part of the cartridge 2 is a bill feeding port 10,
The bill passing between the main feed roller 11 and the separation roller 12 is to be fed through the passage 13 between the guide plates 13a and 13b, and the fed bill is detected by the feed detection sensor 14.

The main feeding roller 11 incorporates a clutch 15 and a brake 16 shown in FIG. 3, a rubber portion 11a for applying a feeding force to a bill is provided on a peripheral surface, and a detecting plate 17 and a synchronous sensor 1 are provided.
The rotation angle is detected by the coexistence with 8.

Between the carry-in port 5 and the feed-out port 10, an auxiliary feed-out roller 19, which is a rubber roller around the entire circumference, is mounted directly above the center of the cartridge 2. The auxiliary feeding roller 19 includes a clutch 20 (see FIG. 3). Reference numeral 21 denotes a gate lever which is separated from and attached to the feeding guide 22 to open and close the feeding port 10.

The control circuit shown in FIG. 2 shows the overall circuit configuration. The clock pulse and the signals from the sensors 14 and 18 as shown in FIG.
4 and input to the CPU 26 via the interface 25,
The CPU 26 controls the driver circuit 28 from these signals according to the program stored in the memory 27, activates the actuators 15 and 20 such as clutches, and performs a predetermined number of bill feeding operations. The operation stops when it is confirmed that the bill dispensing is completed.

FIG. 3 shows a circuit configuration of a main part of FIG. 2, which is issued from the CPU 26 such as an ON signal of the brake 16, an ON signal of the clutch 15, a forced ON signal of the clutch 20, an ON signal of the clutch 20, and the like. The command signal and the amplified signals of the synchronous sensor 18 and the feed detection sensor 14 are input to the driver circuit 28, and the brake 16, the clutches 15, 20 are controlled as described in the following operation.

That is, the mechanism of FIG. 1 has a bill receiving / dispensing function, as is apparent from the configuration described above.

Prior to the start of the feeding operation, the pressing plate 3 is raised, the banknote 4 is pressed against the auxiliary feeding roller 19, and the rotation of the auxiliary feeding roller 19 causes the uppermost banknote 4 to be separated from the separation roller 12 and the main feeding roller 11. And into the gap.

From this state, first, the clutch 15 is moved as shown in FIG. 4A.
When turned on, the main feeding roller 11 rotates. At this time, an ON signal is also sent to the clutch 20 as shown in FIG. 4C, but the clutch 20 is not immediately turned ON because the clutch 20 is also interlocked with the synchronous sensor 18 for extracting the rotation of the main feed roller 11.

The main feeding roller 11 feeds the uppermost banknote 4 through the space between the separation rollers 12 by the rubber portion 11a. However, the separation roller 12 is a rubber roller that does not rotate, and as a result, the next bill is blocked by being hit by the separation roller 12, so that only one bill is fed.

The clutch 15 of the main feeding roller 11 remains ON until a predetermined number of banknotes are fed, but the clutch 20 of the auxiliary feeding roller 19 turns the main feeding roller 11 per banknote.
Turn ON for about 90 degrees of the rotation angle of. This is because the banknotes are continuously fed when the auxiliary feeding roller 19 continues to rotate. ON timing of clutch 20 is the main feeding roller
This is achieved by detecting the 11 detecting plates 17 by the synchronous sensor 18,
Specifically, the rubber portion 11a of the main feeding roller 11 is held for about 90 degrees from around the position where the rubber portion 11a hits the feeding guide 22. Therefore, the signal waveforms are synchronized as shown in FIGS. 4B and 4D.

On the other hand, the feeding detection sensor 14 generates an ON signal each time one bill is detected as shown in FIG. 4E.

However, depending on the state of the stacked bills, a plurality of bills may be fed out in a continuous state.

When this occurs, the passage width of the bill in the feeding detection sensor 14 increases from the normal state t1 in FIG. 4E to t2. This means that the light-shielding time of the feeding detection sensor 14 is measured by counting clock pulses (FIG. 4G) of the tachogenerator 23 that generates a pulse synchronized with the transport speed. It is determined to be taken out at the point (arrow A in FIG. 4).

At this time, the ON signal of the clutch 20 (FIG. 4C) is output.
OFF, and even if the synchronous sensor 18 turns ON, the clutch 20
N, while turning clutch 15 off for a while
Continue to N. That is, the auxiliary feeding roller 19 is kept stopped, and only the main feeding roller 11 continues to rotate. As a result, the taken-out bill is completely fed into the passage 13, while the feeding of the next bill is suppressed because the auxiliary feeding roller 19 is stopped.

After the taken-out banknote is completely sent out to the passage 13, the rotation of the main feeding roller 11 is stopped by turning off the clutch 15 and turning on the brake 16, and the banknote feeding is temporarily interrupted.
The taken-out bill in 13 is collected at a predetermined place.

Once the banknote 4 is taken out like this,
By continuing the rotation of the main feeding roller 11 until the taken-out bill is completely sent out from the pay-out port 10 to the passage 13, it is possible to easily collect the subsequently taken-out bill, and the taken-out bill that is not completely drawn out shields the feeding detection sensor 14. It is possible to eliminate the stop of the operation of the apparatus due to the continuous operation.

In addition, since the auxiliary feeding roller 19 immediately stops rotating due to the occurrence of the take-out, there is no unnecessary feeding of the banknote thereafter, and the banknote is stored in the banknote storage unit 1 in a normal state, thus preparing for the feeding operation to be restarted.

Moreover, after the main feeding roller 11 rotates until the taken-out banknote is completely fed, the main feeding roller 11 stops rotating until the taken-out banknote is collected at a predetermined place, and after this collection. The feeding operation can be restarted.

In the correspondence between the configuration of the present invention and the above-described embodiment, the feeding section of the present invention corresponds to the feeding port 10 of the embodiment, and similarly, the sensor corresponds to the feeding detection sensor 14, and Corresponds to the banknote 4, and the sheet storage unit corresponds to the banknote storage unit 1. However, the present invention is not limited to the configuration of the above-described embodiment.
