Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to a paper sheet reversing device, and more particularly, to a paper sheet reversing device that is installed in an automatic teller machine (ATV) or a deposit machine, and is used to reverse paper sheets such as banknotes inserted face down. This invention relates to an improvement of a paper sheet reversing device that reverses paper sheets face up.

Description of Prior Art FIG. 4 is a diagram showing an outline of a conventional paper sheet reversing device installed in an ATM or a deposit machine, and FIG. 5 is a timing chart for explaining the delay in reversing banknotes.

First, referring to FIG. 4, an 81 sensor 11 is installed at the entrance of the reversing device to detect passing banknotes. A flapper 1 is provided for sorting banknotes. When the front-up banknotes are conveyed, the flapper 1 distributes them to the front-side banknote transport path 2. ], Once the face-down banknotes have been conveyed, they are sorted (pulled) to the reversing machine 4f43. In the reversing mechanism 3, the face-down banknotes are conveyed by rollers 4 and 5. When the tip of the bill hits the stopper 6, the rear edge of the face-down banknote is pulled by the impeller 7 rotating in the closing direction, and rotates counterclockwise around the tip that hits the stopper 6, thereby turning the banknote face up. is reversed.

Then, the back end of the banknote turned over is 1 cola 8.
9 and conveyed, and merges with the conveyance path 2 for face-up banknotes at a merging section 10. An S4 sensor 12 is provided in the confluence section 10, and the S4 sensor 12 detects a face-up banknote and a face-down banknote turned face-up. .

By the way, there are three types of banknotes: 10,000 yen bills, 5,000 yen bills, and 1,000 yen bills, each of which has a different length. For this reason, the timing of feeding out the inverted banknotes differs depending on the type of banknote. That is, as shown in FIG. 5(a), the S1 sensor 11 sequentially detects a face-up banknote and a face-down banknote, and when the face-up banknote is reversed by the reversing mechanism 3 and the S4 sensor 12 detects its passing timing, Compared to the passing timing of the 10,000 yen bill shown in Figure 5(b), the length of the 5,000 yen bill and the 1,000 yen bill is shorter than that of the 10,000 yen bill. As shown in Figure 5(d), the passing timing is delayed little by little.

Therefore, even if a mixture of face-up banknotes and face-down banknotes is conveyed to the entrance of the paper sheet reversing device at a certain interval, the intervals between the banknotes will be different at the exit, which may cause jams or cause problems after the reversing mechanism. There was a problem with the distribution of students by division, which resulted in mistakes.

Purpose of the Invention Therefore, the main object of the present invention is to provide a method for handling paper sheets that are face-down when a plurality of paper sheets of different lengths are conveyed face-up or face-down at predetermined intervals. To provide a paper sheet reversing device which can be reversed face up and fed out at regular intervals.

Structure and Effects of the Invention To summarize the present invention, sorting of paper sheets facing up and paper sheets facing down includes an LC between a means and a reversing mechanism for detecting paper sheets facing down. A detection means is installed, and when the detection means detects a face-down paper sheet, the clock pulse is counted to 51, and when the predetermined number of 31 is reached, a clock pulse is set between the reversing mechanism and the merging path. It is configured to drive the provided rollers to feed paper sheets that have been turned face up into a merging path at regular intervals.

Therefore, according to the present invention, the rollers are driven after a certain period of time has elapsed since a face-down paper sheet is detected, so even if the lengths of the paper sheets are different, the feeding interval can be adjusted. It can be kept constant.

The present invention will be explained in more detail below along with embodiments shown in the drawings.

5.1 Description of examples FIG. 1 is a schematic diagram of an embodiment of the present invention.

The reversing device shown in FIG. 1 is the same as that in FIG. 4 described above except for the following points. That is, between the sorting 1 flapper 1 and the roller 4, there is an S2 sensor 15 for detecting face-down banknotes sorted into the reversing mechanism 3, and a brake 16 and a clutch 17 connected to the roller 8. provided. The brake 16 is for stopping the rotation of the roller 8 until a certain period of time has passed after the S2 sensor 15 detects a face-down banknote. After a certain period R has elapsed, the brake 16 separates from the roller 8, and the clutch 17 rotates the roller 8.

Note that the feeding means 13 is for feeding out banknotes one by one, and the discrimination circuit 14 is for identifying whether the banknotes fed by the feeding means 13 are face up or face down. .

Furthermore, the S3 sensor 18 for detecting the front-up banknotes that have been transported is provided on the front-face banknote transport path 2 .

6- FIG. 2 is a schematic block diagram showing the electrical configuration of an embodiment of the present invention. First, the configuration will be explained with reference to FIG. The discrimination circuit 14 shown in FIG. 1 identifies whether the banknote is facing up or down, and provides the identification signal to the CPU 21. A RAM 22 is connected to the CPU 21 . This RAM 22 includes an area 23 as an S1 counter,
Area 24 as an S4 counter, area 25 as a feed-out control counter, area 26 as an end counter, area 27 for setting the reversal hole monitoring flag to 1~, and setting the passing hole monitoring flag. area 28.

The 81 counter 23 counts 84 clock pulses after the S1 sensor 11 shown in FIG. 1 detects the face-up banknote 2 and the face-down banknote. S4 counter 2
4 counts clock pulses after the S4 sensor 12 detects a banknote. Pay-out control counter 25 counts the time from when the S3t flap 15 detects a face-down banknote to when the roller 8 is rotated. The termination counter 26 counts clock pulses to determine whether the face-down bill has been flipped face-up by the flipping mechanism 3 within a predetermined period of time. The reversal hole monitoring flag area 27 is set when the discrimination circuit 14 identifies a face-down banknote.
This area is used to set the reversal hole monitoring flag. The passage hole monitoring flag area 28 is used as an area for setting the passage hole monitoring flag to the cellar 1 when the discrimination circuit 14 identifies a face-up banknote.

Furthermore, a sensor interrupt circuit 29, a tachogenerator interrupt circuit 30, a solenoid control circuit 31, a clutch control circuit 32, and a brake control circuit 33 are connected to the CPU 21.

The sensor interrupt circuit 29 connects each sensor 11, 1 shown in FIG.
This is for providing an interrupt signal to the CPU 21 when the output signal 2, 15, and 18 output a detection signal. The tacho energy interrupt circuit 30 is a motor (not shown) for conveying banknotes.
When a clock pulse is output from the tachogenerator provided in connection with the tachogenerator, the tachogenerator interrupt signal is output to CP.
This will be given to U21. The solenoid control circuit 31 controls a solenoid for driving the flapper 1. The clutch control circuit 32 is for controlling the clutch 17 provided in relation to the roller 8, and the brake control circuit 33 is for controlling the brake 16.

FIG. 3 is a flowchart for explaining the specific operation of one embodiment of the present invention.

Next, with reference to FIGS. 1 to 3, a specific operation of an embodiment of the present invention will be described.

First, in the initial state, the CPU 21 clears all areas 23 to 28 of the RAM 22 in step (abbreviated as SP in the drawing) SP1. And the CPU
21 gives a feeding command to the feeding means 13 in step SP2.

Then, the feeding means 13 sequentially feeds out the banknotes one by one at regular intervals. The dispensed banknotes include both face-up and face-down banknotes. These banknotes are identified by the discrimination circuit 14 as whether they are face up or face down, and the identification signal is given to the C-9-PtJ 21. The bill identified by the discrimination circuit 14 is detected by the S1 sensor 11. S1 sensor 1
1 detects a banknote, the CPU
An interrupt signal is given to 21. Based on the interrupt signal from the sensor interrupt circuit 29, the CPU 21 performs step S.
At P3, it is determined whether the 81 sensor 11 has detected a banknote.

When the CPU 21 determines that the S1 sensor 11 has detected a banknote, it increments the 81 counter 23 in step SP4. Then, in step SP5, the end counter 26 is turned on, that is, in a count-up enabled state, and in step 9P6, the discrimination result identified by the discrimination circuit 14 is read. In step SP7, the CPU 21 determines whether or not the identification result is a reversed card. When it is not a reverse bill, that is, if it is a face-up bill,
In step SP8, a signal for turning on the solenoid is given to the solenoid control circuit 31. When the solenoid is turned off, the flapper 1 transports the transported banknotes to the front-side banknote transport path 2. At the same time, the CPU 21 sets the passage hole monitoring flag to the area 28 in step SP9.

If the discrimination circuit 1'l identifies a face-down banknote,
In step 5P10, the solenoid is turned on, and the flipper 1 distributes the face-down banknotes to the reversing machine IM3.

Then, in step SP11, a reversal hole monitoring flag is set in area 27.

When the face-down banknotes are sorted to the reversing mechanism 3, S2 t
4-15 detects the face-down banknote. Cl]U21
At step SP12, S2t! is sent from the sentry training circuit 29 to S2t! It is determined whether or not the interrupt signal of 4 is input. S2t? If the interrupt signal from the sensor 18 has been input, it is determined in step 5P13 whether or not the passage hole monitoring flag has been set for the cellar 1. If S 2
When there is an interrupt signal from the t-fusa 18 and the passage hole monitoring flag is not set to the cellar 1, it is a selection mistake, so processing for a selection mistake is performed in step SP1/I. However, if there is an interrupt signal from the S2 sensor 18 and the passage hole monitoring flag is set to the cellar 1, then: 11- This flag is cleared in step S'P15.

If the banknote identified by the discrimination circuit 14 is a face-down banknote,
In step SP16, it is determined whether the S3 sensor 15 has detected a face-down banknote.

Then, in step SPI 7, it is determined whether or not the reverse hole monitoring flag is set for the rear 27.

If it is not set (if it is pulled), it is a selection error, and processing for the selection error is performed in step SP18. However, if the reversal hole monitoring flag is set, this flag is cleared in step 5P19. , the clutch 17 is turned off in step 5P20.
A control signal for turning the brake 16 on is given to the clutch control circuit 32, and a control signal for turning the brake 16 on is given to the brake control circuit 33. That is, the reversing mechanism 3
The rotational force is no longer transmitted to the roller 8 from the clutch 17, and its rotation is stopped by the brake 16.

Then, in step 5P21, the CPU 21 causes the feed-out control tachodynamic force 12-counter 25 to start from 1 to 1.

The face-down banknotes that have passed through the S3 sensor 15 are conveyed by rollers 4.5, and their tips abut against the stopper 6. Then, the rear end of the face-down banknote is hooked by the impeller 7, and rotates counterclockwise in the B1 direction about the tip that abuts the stopper 6. Then, the rear end of the face-down banknote reaches the roller 8 side. At this time, as the rollers 4 and 5 rotate, a clock pulse is output from the tacho generator. The tachogenerator interrupt circuit 30 provides a tachogenerator interrupt signal to the CPtJ21 every time a clock pulse is applied.

The CPU 21 selects the 84 sensor 12 in step 5P22.
It is determined whether or not an interrupt signal from the tachogenerator has been inputted, and if not inputted, it is determined in step 5P24 whether or not a tachogenerator interrupt signal has been inputted. If it has been input, it is determined in step 5P25 whether or not the feed-out control tachodynamic counter 25 is in the on state. If it is in the on state, the feedout 13-control tacho energy counter is updated in step 5P26. Then, in step 5P27, it is determined whether or not the feed-out control tachodynamic counter 25 has reached a predetermined count value, and if not, in step 5P29, it is determined whether the end counter 26 has counted a predetermined count value. . If the process has not ended, the process returns to step SP3.

If the interrupt signal from the 81 sensor 11 has not been input in step SP3, the process jumps to step SP12, and in step SPI 2 the S2 sensor 18
Determine whether an interrupt signal from is input. If no interrupt signal has been input, the process jumps to step SP16, and it is determined whether an interrupt signal from the S3 sensor 15 has been input. If not entered, step 5P22
, and it is determined whether an interrupt signal from the S4 sensor 12 has been input. If it has not been input, it is determined in step 5P24 whether or not a tachogenerator interrupt signal has been input.

This operation is repeated, and when the number of outputs of the feed-out control tachogen counter 14-counter 25 reaches a predetermined value, it becomes 1, that is, S
3 sensor 15 detects a face-down banknote, the face-down banknote is reversed by the reversing mechanism 3, the rear end is stopped by the stopped roller 8, and when a predetermined period of time has elapsed, the banknote is fed out. Control] In step 5P27, it is determined that the t1 value of the generator counter 25 has reached a predetermined value.

Then, in step 5P28, the clutch 17 is turned on and the brake 16 is turned off. Then,
The roller 8 rotates, and the banknotes turned face up are brought to the confluence section 1.
0. If the end counter 26 is on in step 5P29, step 5P30
The end counter 26 is updated.

In step 5P31, it is determined whether the secondary value of the end counter 26 has reached a predetermined value, and if it has not reached the predetermined value (J), the process returns to step SP3.

Then, the operations from step SP3 to step 5P30 are repeated until the end counter 26 reaches a predetermined value. If the count value of the end counter 26 reaches the predetermined value -15=, in step 5P32, the S1 counter 23
It is determined whether the counted value of 84 and the value of the 84 counter 24 match. If they do not match, it is abnormal, so
In step 5P33, abnormal termination processing is performed, and if they match, normal termination processing is performed in step 5P34, and the series of operations ends.

As described above, according to this embodiment, the clutch 17 and the brake 16 are provided in association with the roller 8 for delivering the banknotes reversed face up by the reversing mechanism 3 to the merging section 10, and the S3 sensor 15 is Since the roller 8 does not rotate if a predetermined period of time elapses after a banknote is detected, the banknotes have different lengths, such as 10,000 yen bills, 5,000 yen bills, and 1,000 yen bills. Even in the above case, it is possible to keep the intervals between the bills at the entrance side of the reversing device and the intervals between the bills at the exit side of the reversing device constant.
