Description

Detailed Description of the Invention "Industrial Application Field" The present invention is capable of attracting paper sheets loaded in a holder to suction shafts evenly arranged on a concentric circle of a rotating cylinder and turning them over one by one. Along with counting,
When the preset number of paper sheets has been counted,
The present invention relates to a paper sheet counter that allows a desired number of paper sheets to be taken out by interrupting the counting operation.

"Conventional technology" Conventionally, this type of paper sheet counting machine was
There is a "paper sheet counter" shown in Publication No. 787.

This "paper sheet counting machine" counts the paper sheets loaded in the holder by attracting them to a suction shaft evenly arranged on the concentric circle of a rotating tube and flipping them one by one. When the number of sheets has been counted, the separator of the so-called batching device is pressed against the surface of the set number or more of sheets that have not yet been counted on the holder side, and the suction shaft is used to peel them up. The counting operation is interrupted so that the desired number of sheets can be taken out.

In other words, a batch device is a device that uses a separator to forcibly press down on the part where more than a set number of paper sheets are picked up by the remaining vacuum pressure in the suction shaft and turned over. This is to prevent it from being turned over.

``Problem to be solved by the invention'' In this way, because paper sheets are forcibly prevented from being turned up by separators, paper sheets, such as circulation tickets, become easily damaged and cut. In the case of banknotes, there has been a problem in that they may be pulled and cut between the part pressed by the separator and the part sucked by the suction shaft.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a paper sheet counting machine that can take out a desired number of paper sheets without requiring a so-called batching device having a separator. The purpose is to

"Means for solving the problem" In order to achieve the above object, the first invention:
When the number of sheets of paper turned over by the suction shaft reaches a preset number plus one sheet, the rotation of the rotary tube is abruptly stopped and the operation of turning over subsequent sheets of paper is interrupted. , a separation stop function that causes the set number of sheets plus the first sheet to be stopped by the suction shaft at an intermediate separation position away from uncounted sheets and counted sheets; and a rotation cylinder position sensor ON/OFF function. Based on the OFF signal,
It monitors whether or not the paper sheets are separated at the intermediate separation position, which is separate from the uncounted paper sheets and the counted paper sheets, and outputs a batch failure alarm when the paper sheets are not at the intermediate separation position. At the same time as the separation monitoring function and the separation stop operation by the separation stop function, the supply of vacuum pressure to the suction shaft is stopped, and the separation stop function separates both the uncounted paper sheets and the counted paper sheets. In order to combine the set number of sheets plus the first sheet stopped at the intermediate separation position with the uncounted sheets, the rotary cylinder in the stopped state is rotated by a predetermined angle in the opposite direction to that during counting. It has a rotation function.

In the second invention, when the number of sheets turned over by the suction shaft reaches a preset number plus one sheet, the rotation of the rotary cylinder is abruptly stopped, and the subsequent turning of the sheets is stopped. a separation stop function that interrupts the picking operation and stops the set number of sheets plus the first sheet by the suction shaft at an intermediate separation position separated from both uncounted sheets and counted sheets; Based on the ON/OFF signal of the cylinder position sensor,
It monitors whether or not the paper sheets are separated at the intermediate separation position, which is separate from the uncounted paper sheets and the counted paper sheets, and outputs a batch failure alarm when the paper sheets are not at the intermediate separation position. At the same time as the separation monitoring function and the separation stop operation by the separation stop function, the supply of vacuum pressure to the suction shaft is stopped, and after the vacuum pressure ceases to act, the separation stop function stops the uncounted paper. In order to bring together the set number of paper sheets that have been stopped at an intermediate separation position away from both the leaves and the counted paper sheets, the rotary cylinder in the stopped state is moved in the same order as during counting. It also has a collective rotation function that further rotates a predetermined angle in the direction.

"Operation" According to the first invention, the number of paper sheets turned over by the suction shaft is a preset number plus 1.
When the number of sheets is reached, the rotation of the rotary tube is suddenly stopped and the operation of turning over subsequent sheets is interrupted, and the set number of sheets plus the first sheet is not counted by the suction shaft. It is stopped at an intermediate separation position away from the paper sheets and the counted paper sheets, and at the same time, the supply of vacuum pressure to the suction shaft is stopped.

Then, for the set number of sheets plus the first sheet that is stopped at an intermediate separation position that is far away from both uncounted sheets and counted sheets, the rotary cylinder in the stopped state moves in the opposite direction to the one at the time of counting. By being rotated by a predetermined angle, the paper sheets are returned together with the uncounted paper sheets, and the so-called batch processing is completed.

In addition, during such batch processing, if sheets do not stop at the intermediate separation position, a batch failure alarm is output, so the operator can immediately notify that an abnormality has occurred during batch processing. This makes it possible to quickly move on to batch processing again, and as a result, batch processing can be performed reliably and efficiently.

Further, according to the second invention, when the number of sheets turned over by the suction shaft reaches a preset number, the rotation of the rotary tube is abruptly stopped and the following sheet is removed. At the same time, the turning operation is interrupted, and the set number of sheets is stopped by the suction shaft at an intermediate separation position away from uncounted sheets and counted sheets, and at the same time, the vacuum is applied to the suction shaft. The pressure supply is stopped.

After the vacuum pressure of the suction shaft is no longer applied, the set number of sheets is stopped at the intermediate separation position, which is far away from both the uncounted sheets and the counted sheets. By further rotating the rotary cylinder by a predetermined angle in the forward direction from the time of counting, the sheets are collected together with the sheets that have already been counted, completing the so-called batch processing.

In addition, during such batch processing, if sheets do not stop at the intermediate separation position, a batch failure alarm is output, so the operator can immediately notify that an abnormality has occurred during batch processing. This makes it possible to quickly move on to batch processing again, and as a result, batch processing can be performed reliably and efficiently.

"Example" Below, first, the first invention will be described.
An explanation will be given based on an embodiment applied to a banknote counting machine shown in FIGS.

First, the structure of the banknote counting mechanism will be explained with reference to FIGS. 1 to the counting position shown by the solid line in FIG. 1 or the standby position shown by the chain line in FIG. , the suction shaft 5 on the rotary tube 3 is rotated clockwise around the shaft 6, vacuum pressure is applied to the inside of the suction shaft 5, and the banknotes S on the holder 1 are turned over one by one and counted. , the banknote S is determined by reading the reflected light of the light irradiated onto the surface of the banknote S by a light receiver from a light projector, which will be described later.

The holder 1 is provided with a base plate 1a that supports the banknote S from the back side (opposite side of the suction shaft 5), and the surface 1b of the base plate 1a is colored black to reduce the level of reflected light. It is formed.

The shafts 4 and 6 of the rotary cylinder 3 and the suction shaft 5 are formed in a hollow shape as shown in FIG.
Suction port 9 of vacuum pump 8 via suction line 7
The vacuum pressure of this vacuum pump 8 is connected to the opening 1 provided in a part of the outer periphery of the suction shaft 5.
By acting on the banknotes S through the suction shaft 5, the banknotes S are attracted to the suction shaft 5.

Further, a pressure sensor 1 is provided in the middle of the suction pipe line 7.
1 is provided, and this pressure sensor 11 detects whether the vacuum pressure within the suction pipe line 7 has risen to a level that allows the bill S to be sucked.

On the other hand, an exhaust pipe 13 is connected to the exhaust port 12 of the vacuum pump 8, and the tip of the exhaust pipe 13 is used to blow exhaust gas onto the sides of the banknotes S to easily separate the banknotes S from each other. On the other hand, an exhaust nozzle 14 is provided in the middle of the exhaust pipe line 13 to switch the exhaust gas to emitted light 15 when the banknotes S are not being counted, thereby preventing the generation of noise from the exhaust nozzle 14. A solenoid valve 16 is provided.

In addition, each of the suction shafts 5 has a structure shown in FIGS.
As shown in FIG. 3, a pair of position regulating pieces 5a are fixed.

The position regulating piece 5a protrudes from the side surface of the suction shaft 5 and is provided so as to sandwich an opening 10 of the suction shaft 5 between the position regulating pieces 5a. When the banknote S is attracted, the banknote S is supported from the side to prevent the banknote S from falling or bending.

The position regulating piece 5a allows the suction shaft 5 to maintain the upright state of the bill S which has been attracted and separated, thereby detecting whether or not double feeding is being carried out (in FIG. 1, the bill S is The banknote S is positioned at the adsorbed and separated position shown by .

Further, a plurality of actuation pieces 17 made of a magnetic material are attached to the outer circumference of the rotary cylinder 3, and each suction shaft 5 is moved to a standby position (opening) depending on whether or not these actuation pieces 17 actuate the magnetic sensor 18. Part 10 is banknote S
and the inside of the suction shaft 5 is in communication with the vacuum pump 8), or the starting position (the position immediately before the opening 10 directly faces the banknote S,
In addition, it is detected whether the inside of the suction shaft 5 is at a position where it is cut off from the vacuum pump 8.

In addition, in FIG. 3, reference numeral 19 is a counting motor that drives the rotary cylinder 3 via a belt 20;
1 is a pump motor that drives the vacuum pump 8 via a belt 22, 23 is a holder motor that rotates the holder 1, and 24A and 24B indicate whether the holder 1 is in the closed position (close to the suction shaft 5) or open. This is a holder position detection switch that detects whether the holder is in the holder position (a position away from the suction shaft 5).

Next, a stamping mechanism for stamping a confirmation stamp on a bundle of banknotes S will be explained with reference to FIGS. 1 and 2.

In FIG. 1, a stamping mechanism 30 is provided on the side of the holder 1. Supported seal 30
A, a pressing body 30B that presses the rear end surface of the seal stamp 30A, and a stamping solenoid 30C that presses and drives this pressing body 30B.

On the other hand, what is indicated by the reference numeral 31 in FIG. 2 is a stamping mechanism provided below the holder 1, and this stamping mechanism 31
The seal stamp 31A is supported movably in the direction of arrow E--L in FIG. 1, a pressing body 31B that presses the rear end surface of the stamp 31A, and a stamping solenoid 31C that presses and drives this pressing body 31B.

Next, a mechanism for detecting double feeding of banknotes S turned over by the suction shaft 5 will be explained with reference to FIG. 1.

Reference numerals 37 and 38 in FIG. 1 indicate a double feed detection lamp and a light receiving element (these elements constitute a double feed detection sensor), and 39 indicates a double feed detection lamp and a light receiving element (these elements constitute a double feed detection sensor). This is a condensing lens that condenses transmitted light from the banknote S onto the light receiving element 38.

Both the double feed detection lamp 37 and the light receiving element 38 are provided toward the rotary barrel 3 side, and the light beam emitted from the double feed detection lamp 37 is directed toward the flipped banknote Sa. The beam is irradiated from a direction crossing the banknote Sa, and is irradiated to approximately the center position of the peeled-off portion of the banknote Sa.

The light irradiated and transmitted to the banknote Sa is focused on the light receiving element 38 by the condensing lens 39, and the amount of light is detected. Based on the amount of transmitted light detected by the light receiving element 38, double feeding is determined. It's becoming more common.

That is, if the amount of transmitted light is above a predetermined value, normal feeding (single sheet feeding) is determined, and if the amount of transmitted light is less than a predetermined value, it is determined to be double feeding.

Next, a discrimination mechanism for discriminating the denomination and front and back of the banknote S will be described with reference to FIGS. 1 and 2.

In FIG. 2, the reference numeral 40 is a light projector that irradiates light onto the frontmost banknote Sb of uncounted banknotes that is about to be turned over by the suction shaft 5. bill
It is a light receiver that receives the reflected light of the light irradiated on Sb, and the light irradiated from the light projector 40 is
The area of Sb including at least the area E indicated by the two-dot chain line in the figure is irradiated.

The light receiver 41 also includes an area sensor 42 that generates an electrical signal according to the pattern on the surface of the banknote.
and a condensing lens 43 that condenses reflected light from the banknote Sb onto the area sensor 42.

The area sensor 42 detects the area E of the banknote Sb.
It is configured so that a plurality of horizontal line patterns suitable for discrimination can be detected and read from among them, and as described later, it is operated by a trigger signal output from the discrimination control circuit 46. The amount of reflected light on a specific line in the area E is converted into a time-series electric signal (analog signal) and output.

That is, the area sensor 42 is configured to be able to output data in the horizontal direction for the line after setting a line in the vertical direction, and the horizontal direction corresponds to the X coordinate of the area E. , whose vertical direction corresponds to the Y coordinate of area E, and by the correspondence between the vertical and horizontal coordinates of the area sensor 42 and the XY coordinates of area E, the surface pattern (line data) in area E can be expressed as, for example, , Y=1, Y=3 and the lines can be specified and read.

In this way, the read area data is A/D converted and stored as described later, and compared with reference data stored in the ROM 64 to determine the denomination of the banknote Sb. A determination will be made.

Next, with reference to FIG. 4, a counting control circuit 45 (separation stop function, return rotation function, set rotation function) and discrimination control circuit 46 (denomination discrimination function) that respectively control the counting mechanism and discrimination mechanism will be explained.

That is, the counting control circuit 45 has a ROM 47 that stores a counting control program (see FIGS. 5 and 6), which will be described later, and the like, and writes and reads various data according to the programs stored in the ROM 47. It is composed of a RAM 48 that performs this, and a CPU 49 that controls these.

Furthermore, the CPU 49 is connected via the input side I/O port and the receiver 51 to a start switch 52 for instructing the start of counting operation, a detection mode switch 53 for determining the denomination and double feed, and a detection mode switch 53 for determining the front and back sides. A holder closed position sensor 24 is connected to the front/back mode switch 54 and detects whether the holder 1 is in the closed position or the open position.
A and the holder open position sensor 24B, and further,
The rotary cylinder position sensor 18, pressure sensor 11, and other operation switches 55 including a clear switch and the like are connected to each other.

In addition to the clear switch, the operation switch 55 includes a mode selection switch that selects modes such as count addition, designation (batch), re-examination (check), stamping, amount calculation, etc., and an abnormal termination switch as described later. 10,000-note button, 5,000-note button for inputting denomination confirmation for abnormal banknotes when counting is interrupted.
There are senken buttons (this confirmation button is also used to confirm different denominations), etc.

Here, to briefly explain the mode, "count and addition" is a mode in which the number of banknotes is counted and the counted value is accumulated for each counting operation, and "designation (batch)" is a mode in which the number of banknotes is counted and the counted value is accumulated for each counting operation. In this mode, the number of banknotes is specified as, for example, 50, and when counting of 50 banknotes is completed, counting is interrupted and separated into 50 banknotes that have been counted and banknotes that have not yet been counted. (Check) is a mode to check whether there are a set number of banknotes in a bundle, and
"Stamping" is a mode in which a banknote is re-verified and, if the re-verification result is correct, a stamp is stamped on the band from the side or from below. This mode calculates and displays the total amount of banknotes that are counted.

A plurality of these modes can be set at the same time, unless their functions conflict with each other.

By the way, the start switch 52 shown in FIG.
In this embodiment, the push button 60 (see FIG. 1) provided on the holder 1 is used. It may also be used as a start switch 52.

Further, the CPU 49 is connected via an output side I/O port 61 and a driver 62 to marking solenoids 30C and 31C, and a double feed detection lamp 37.
Alternatively, the lamp consisting of the projector 40, the holder motor 23, the counting motor 19, the pump motor 21, the solenoid valve 16, the operation panel for the bill counting function (not shown), etc. displays the number of bills installed, presence or absence of abnormality, etc. A display unit 63 is connected to each display unit.

On the other hand, the discrimination control circuit 46 has a ROM 64 that stores discrimination control programs (see FIGS. 7 and 8), and writes and reads various data according to the programs stored in the ROM 64. It is composed of a RAM 65 and a CPU 66 that controls them.

Further, an area sensor 34 is connected to the CPU 66 via an output side I/O port 70 and a drive circuit 71, and the output of this area sensor 34 is sent to an amplifier 72, an A/D converter 73, and an input side I/O port. The data is inputted to the RAM 65 via 74.

Note that from the drive circuit 71 to the area sensor 34
The drive signal supplied to the banknote is composed of an X-axis drive signal and a Y-axis drive signal, and by outputting these X-axis drive signals and Y-axis drive signals, the surface pattern at a specific position in area E of the banknote is determined. (area data)
is now read out.

When extracting surface pattern data in area E, first output a Y-axis drive signal to determine the Y coordinate of area E, then output an X-axis drive signal to determine the area What is necessary is to change the X coordinate of E in a certain direction.

In other words, set the Y coordinate to 1 and convert the data in area E to line data (X, 1) (however, X
= 1 to
X=1 to Xmax), a plurality of read line data are stored in the RAM 65, and compared with reference data stored in the ROM 64.

On the other hand, similar to the area sensor 34, the A/D converter 73 is connected to a light receiving element 38 of a double detection sensor via an amplifier 78.

Furthermore, analog switches 79 and 80 are provided between the amplifiers 72 and 78 and the A/D converter 73, respectively, and are operated by switching signals from the output side I/O port 70. 79 and 80, the output signal of either the area sensor 34 or the light receiving element 38 of the dual detection sensor is sent to the A/D converter 73.

Further, the CPU 49 of the counting control circuit 45 and the CPU 66 of the discrimination control circuit 46 are connected to each other via data transfer I/O ports 81 and 82, and can mutually convert data and operate in conjunction. It is configured as follows.

Below, Figures 5 to 6, Figure 9, and Figure 1 are shown below.
According to FIGS. 14 to 14, the counting control circuit 45
The contents of the program stored in the ROM 47 will be explained together with the operation of the banknote counting machine.

Furthermore, Figure 5 consists of two figures, A and B.
Furthermore, FIG. 6 consists of four diagrams A, B, C, and D.

Furthermore, SN in FIGS. 5 and 6 indicates step N in the following explanation, and FIGS.
Tn in the figures to FIG. 14 indicates timing Tn in the following explanation.

(a) Counting control operation 1 (see Figures 5A to B and Figure 9) Figure 5A <Step 1> Power on <Step 2> The holder open position detection sensor 24A is activated,
It is determined whether the holder 1 is in the open position or not. If NO, the holder motor 23 is driven to open to set the holder 1 to the open position (step 3), and if YES, the next step is started. Proceed to step 4.

<Step 4> Based on the presence or absence of an output from the rotary cylinder position sensor 18, it is determined whether the suction shaft 5 is in the standby position (that is, the position where the suction shaft 5 directly faces the banknote S),
If NO, the counting motor 19 is driven forward at low speed (in the counting direction) to set the suction shaft 5 to the standby position (step 5), and if YES, the process advances to the next step 6.

<Step 6> Determine whether or not the mode setting switch has been set. If YES, the mode operated according to the various mode setting operations is memorized (Step 7); if NO, the mode is stored. Next step 8
Proceed to.

<Step 8> Start signal (ST) from start switch 52
Determine whether or not is output, and if NO,
Returning to step 6, if YES, proceed to the next step 9 (timing T1).

<Step 9> The holder closed position detection sensor 24B is operated,
It is determined whether the holder 1 is in the closed position or not. If NO, the holder motor 23 is driven to close and the holder 1 is set to the closed position (step 10), and if YES, the next step is started. Proceed to 11 (timing T2).

<Step 11> A pump drive signal (PMP) is output to drive the pump motor 21, and a solenoid valve drive signal (SV) is output to switch the solenoid valve 16 to the exhaust nozzle 14 side.

<Step 12> Depending on the presence or absence of the output from the rotary cylinder position sensor 18, the suction shaft 5 is at the starting position (that is, the position immediately before the opening 10 of the suction shaft 5 faces the banknote S, and the inside of the suction shaft 5 is is in the position where it is cut off from the vacuum pump 8), and if NO, the counting motor low speed reverse drive signal (CMD-R)
is output, the counting motor 19 is driven in reverse at low speed (in the opposite direction to that used during counting) to set the suction shaft 5 to the starting position (step 13), and if YES, proceed to the next step 14. (timing T3).

<Step 14> Wait for the pressure judgment signal (VSW) to be output, that is, wait for the vacuum pressure in the suction pipe 7 to rise to a predetermined value, and then proceed to the next step 15 (timing T4). ).

<Step 15> By outputting the pressure judgment signal (VSW), the counting motor forward rotation drive signal (CMD-FF) is output.
is output, and high-speed rotation of the rotary cylinder 3 and the suction shaft 5 is started.

Fig. 5B <Step 16> The suction shaft 5 attracts and turns up the banknotes S one by one, and in parallel with this turning-up operation, the rotary cylinder position sensor 18 counts each time a signal (SNS) is generated. The signal (CNT) is output and the banknote S
is counted (timing T6 to Tm).

Furthermore, in the mode for discriminating banknotes S, a trigger signal (TRG) for extracting the detection data of the area sensor 42 is output at approximately the same timing, and the banknote S is discriminated.

<Step 17> As the uncounted banknotes S on the holder 1 disappear and the suction shaft 5 is no longer able to suck the banknotes S, the vacuum pressure in the suction pipe 7 drops and the pressure sensor 11 turns OFF. , pressure judgment signal (VSW)
is no longer output, or as described later, when the suction shaft 5 completes the turning operation of the set number of banknotes S in the batch mode and the rotary tube 3 suddenly stops, the subsequent turning of banknotes S is stopped. If the picking operation is canceled, normal end YES
If so, proceed to the next step 18; otherwise, proceed to step 30 as NO.

Note that, as will be described later, the detection of residual errors and number-of-sheets mismatch errors is determined after normal termination, so these are included in normal termination.

<Step 18> The output of the counting motor forward rotation drive signal (CMD-FF) is stopped, and instead, the counting motor brake signal (CM-BRK) is output, and the counting motor 19 is suddenly stopped (timing Tm+1).

At the same time, the output of the pump drive signal (PMP) and the solenoid valve drive signal (SV) is stopped, the pump motor 21 is stopped, and the solenoid valve 16 is switched to the discharge port 15 side.

<Step 19> Determine whether batch mode is ON or not. If YES, proceed to step 20; if NO, proceed to step 22.

<Step 20> As will be described later, it is determined whether the batch operation has ended normally. If YES, proceed to step 22; if NO, proceed to step 21.

<Step 21> Since the batching operation is not performed normally and it is unclear whether the set number of banknotes and uncounted banknotes have been reliably separated, an alarm signal (a signal that drives a buzzer, etc.) indicating the abnormality is output.

<Step 22> As described later, it is determined whether the holder 1 open signal has been output automatically depending on the processing mode or by operating the clear button (clear switch), and if YES, the Returning to step 2 in FIG. 5A (timing Tn), if NO, the process waits at step 22.

When the process returns to step 2, the opening position setting operation of the holder 1 and the standby position setting operation of the suction shaft 5 are performed as described above, and counting is started immediately by the next start signal (step 8). It will be put on standby until it can start.

<Step 30> If it is not determined in step 17 that the cycle has ended normally, in step 30, the rotating cylinder 3 suddenly stops due to error detection (determination error, different denomination, front and back mismatch, double suction detection) to be described later. Then, the suction shaft 5 prevents the bill from being turned over, and it is determined whether or not there is an abnormal end in which the counting is interrupted. If YES, proceed to step 31; if NO, return to step 16. .

As mentioned above, as long as the pressure judgment signal (VSW) is output (NO),
Alternatively, unless a batch operation is performed, steps 16, 17, and 30 are looped and a counting operation is performed as described later.

<Step 31> When it is determined that the process has ended abnormally, the counting motor 19 is suddenly stopped, the pump motor 21 is stopped, and an operation for separating and stopping the abnormal banknotes is performed.

Note that the separation stop operation at this time is the basis of the batch operation described later, so the processing from step 31 to step 35 described later will be explained in the 11th step.
This will be explained in detail with reference to the state explanatory diagram shown in FIG. 12 and the time chart shown in FIG. 13.

That is, as shown in FIG. 11, the rotating barrel position sensor 18 detects the actuating piece 17 provided around the rotating barrel 3, and the rotating barrel position sensor 18 detects the operating piece 17 by the timing T81 when the rotating barrel position sensor output signal (SNS) rises. , it is assumed that the discrimination process for banknote Sa has been completed and this banknote Sa has been determined to be an abnormal banknote.

Then, at this timing T81, as shown in FIG. 13, a counting motor brake signal (BRK) is given instead of the counting motor drive signal (CMD forward rotation), and the rotation cylinder 3 in which the suction shaft 5 is arranged is Rotation is suddenly decelerated.

Thereafter, at timing T81, the actuating piece 17 detected by the rotary cylinder position sensor 18 continues until it is no longer detected by the rotary cylinder position sensor 18, that is, until the rotary cylinder position sensor output signal (SNS) falls. Within rotation range (11th
(within the rotation range from the position shown in the figure to the position shown in Fig. 12), for example, at the timing shown in Fig. 13.
At T82, the rotation of the rotary cylinder 3 completely stops.

At this timing T82, as shown in FIG. 12, the abnormal banknote Sa is located at an intermediate separation position away from both the uncounted banknotes (the frontmost banknote is represented by Sb) and the counted banknotes Sc and Sd. It will be stopped.

Note that the banknote Sb immediately after the abnormal banknote Sa that has been separated and stopped is due to the residual vacuum pressure in the suction shaft 5.
At the time of separation stop operation, the first
As shown in Figure 2, the banknote Sb is in a bent state as it is attracted to the suction shaft 5, but due to its own stiffness (elasticity), it immediately returns in the direction of the arrow.

<Step 32> Abnormal banknote Sa is the first banknote due to sudden stop of counting motor 19.
As shown in FIG. 2, it is determined whether or not the separation is reliably stopped at the intermediate position. If YES, the process proceeds to the next step 33, and if NO, the process proceeds to step 40.

In this case, whether or not the rotating cylinder position sensor output signal (SNS) remained ON until the rotation of the rotating cylinder completely stopped (for example, within a certain period of time from timing T81 to timing T83). Depending on this, it can be determined whether or not the separation has been reliably stopped.

<Step 33> It is determined whether or not the separated and stopped abnormal banknotes Sa are re-counted by the retry process described later and are continuously determined as abnormal banknotes. If NO, proceed to the next step. The process advances to step 34, and if the same banknote is consecutively determined to be abnormal banknotes (YES), the process advances to step 36.

<Step 34> In order to perform a retry process to automatically re-identify the abnormal bill Sa separated and stopped at the intermediate separation position shown in Fig. 12, the counting motor 19 is driven in reverse at low speed (Step 35), After setting the suction shaft 5 to the starting position, the process returns to step 11 in FIG. 5A and the discrimination operation for the abnormal banknote Sa is performed again.

That is, at timing T83, a counting motor drive signal (CMD low speed reverse rotation) is applied instead of the counting motor brake signal (BRK) to cause the counting motor 19 to start reverse rotation at a low speed.

At timing T84 during this reverse operation,
As shown in FIG. 12, the suction shaft 5 located between the abnormal banknote Sa and the uncounted banknote Sb is reversed to the starting position shown in FIG. The abnormal banknote Sa became the 11th banknote.
The banknote Sa is returned to the position shown in the figure, and further, at timing T85, the suction shaft 5 located between the abnormal banknote Sa and the counted banknotes Sc and Sd in FIG. 12 is reversed to the starting position shown in FIG. 11. As a result, the separated and stopped abnormal banknotes Sa become uncounted banknotes Sb
become together with

Then, at timing T85, a counting motor brake signal (BRK) is applied again instead of the counting motor drive signal (CMD low speed reverse rotation) to stop the motor at this position.

When the process returns to step 11 in Fig. 5A, the pump motor 21 is driven again, and when the pressure judgment signal (VSW) is output again (timing T86), it is replaced with the counting motor brake signal (BRK). A counting motor drive signal (CMD forward rotation) is given to automatically restart the discrimination operation for abnormal banknotes Sa (after timing T87).

Next, steps 36 to 41 will be described regarding the process to be performed when the separated and stopped abnormal banknotes Sa are re-counted in the previous retry process and are again consecutively determined as abnormal banknotes Sa. explain.

The processing from step 36 to step 41 will be explained in detail with reference to the state diagrams shown in FIGS. 11 and 12 and the time chart shown in FIG. 14.

<Step 36> As shown in FIG.
Since the abnormal banknote Sa is separated and stopped at a position relatively close to the counted banknotes Sc and Sd, it may be difficult for the operator to visually confirm the abnormal banknote Sa.

In order to solve this problem, it is better to reverse the suction shaft 5 (rotary tube 3) from the separation stop state position shown in FIG. 12 to the banknote Sa position shown in FIG. 1, and then return the suction shaft 5 to the standby position. Process this step 36
This is done between steps 39 and 39.

That is, at timing T103, a counting motor drive signal (CMD) is output in the reverse direction,
The counting motor 19 is driven in reverse at low speed (step 37) until the suction shaft 5 returns to the starting position shown in FIG. 11 (while this step 36 is NO). This step 36 is YES
If: At timing T104), the next step
Proceed to 38.

<Step 38> After the suction shaft 5 is returned to the starting position shown in FIG. The counting motor 19 is driven in normal rotation at low speed (step 39) until the standby position shown in Figure 1 is set (while this step 38 is NO). case:
At timing T106), proceed to the next step 40.

<Step 40> Continuous abnormal banknotes after steps 33 to 39
If Sa is detected and terminates abnormally, or
In the case of an abnormal termination in which separation and stop of the abnormal banknote Sa fails in step 32, the denomination of the abnormal banknote Sa is visually confirmed by the operator.

In this case, as shown in FIG. 1, the abnormal banknote Sa is set at a position where visual confirmation can be easily performed, so that the operator can quickly confirm the abnormal banknote Sa.

Then, by operating the confirmation switch, it is determined that the continuous count is YES, and the process proceeds to step 11.

Thereafter, the pump motor 21 is started to be driven and the pressure determination signal (VSW) is output (step 14YES), so that the operation for determining whether or not the uncounted banknotes Sb are turned over is restarted.

On the other hand, in this step 40, while the confirmation step is not operated (while the continuous count is NO), it is determined in step 41 whether or not the clear button has been operated, and if the clear button has been operated (YES),
From step 41, the process returns to step 2 in the same way as step 22 described above, and if step 41 is NO
In this case, the process waits in a loop of steps 40 and 41.

Next, details of the counting process flow in the CPU 49 will be explained with reference to FIGS. 6A to D, and further details of the discrimination process flow in the CPU 66 will be explained with reference to FIGS. 7 and 8.

(b) Counting control operation 2 (see FIGS. 6A to 6D) First, the control during counting will be explained with reference to the flow shown in FIG. 6A.

Figure 6A <Step 100> start <Step 101> The pump motor 21 starts to drive.

<Step 102> Rotating tube position sensor output signal (SNS) ON-
Based on the OFF state, it is determined whether the suction shaft 5 is at the starting position (SNS is OFF), and if NO, the counting motor 19 is reversed at low speed to set the suction shaft 5 at the starting position. (Step 103), YES
If so, proceed to the next step 104.

<Step 104> Determine whether or not the detection mode switch 53 is ON, that is, whether or not it is necessary to read the pattern on the surface of the banknote.If YES,
The discrimination ON signal and the front/back mode signal (however, only when the front/back mode switch 54 is ON, the same applies hereinafter) are output to the discrimination control circuit 46 (discrimination routine shown in FIG. 7) (indicated by the arrow), and the double feed is performed. The detection lamp 37 and the floodlight 40 are turned on (step 105).

If the detection mode switch 53 is OFF, it is determined that only counting is to be performed, and the process proceeds to the next step 106.

<Step 106> This step continues until the vacuum pump 18 is driven and the suction shaft 5 is set to the starting position, so that the vacuum pressure inside the suction shaft 5 increases and the pressure judgment signal (VSW) is output. Wait at 106.

<Step 107> When the pressure judgment signal (VSW) is output, the counting motor 19 starts rotating at high speed in the forward rotation direction.

<Step 108> It is detected whether or not the rotary tube position sensor output signal (SNS) which is in the OFF state has reached the rising time to be in the ON state. If YES, the process proceeds to the next step 109.

<Step 109> A trigger signal (TRG) is output to the discrimination control circuit 46 (discrimination routine shown in FIG. 7) at the same timing as in step 108 (indicated by an arrow).

<Step 110> Rotating cylinder position sensor output signal (SNS) ON-
Detects the OFF state. If ON (YES), proceed to the next step 111; if NO, proceed to step 116.
Proceed to.

<Step 111> Determine whether the pressure judgment signal (VSW) is ON or not. If ON (YES), proceed to the next step 112, and if OFF (ON), proceed to step 180. It then outputs a discrimination OFF signal to the discrimination control circuit 46 (discrimination routine shown in FIG. 7) (indicated by an arrow), and drives the counting motor 19, pump motor 21, double feed detection lamp 37, and floodlight 40. Stop lighting (step 181)
After that, the process advances to step 182 in FIG. 6D to perform normal termination processing.

<Step 112> Determine whether the detection mode switch 53 is ON or not, and if YES, proceed to the next step 113.
If NO, proceed to step 114.

<Step 113> As will be described later, when a different denomination is detected, when a discrepancy between the front and back sides is detected in the front/back discrimination mode, when it is determined that there is an abnormality in discrimination because it does not match all the reference patterns, or when two When heavy adsorption is detected, it is determined whether there is an input of an error signal (indicated by an arrow) output from the determination control circuit 46 (determination routine shown in FIG. 7), and if YES, In order to perform retry processing or confirmation processing for the error banknote (abnormal banknote), the process advances to step 135 in FIG.

<Step 114> Determine whether batch mode is ON or not. If YES, proceed to the next step 115.
If NO, the process returns to step 110.

<Step 115> The number of banknotes turned over (count value) is compared with a preset value, and it is determined whether the two values match, and it is determined that the count value has not reached the set value. If the answer is NO, the process returns to step 110 and it is determined that the count value has reached the set value.
If YES, the process proceeds to step 120 of FIG. 6B for so-called batch processing.

In this way, as long as the rotary tube position sensor output signal (SNS) is ON, the pressure judgment signal (VSW) is ON, no error signal is input, and a match in the batch mode is not obtained, the step The routine continues from step 110 to step 115, and when the rotary cylinder position sensor output signal (SNS) turns OFF in step 110, the routine proceeds to step 116.

<Step 116> As in step 111 above, determine whether the pressure judgment signal (VSW) is ON or not.
If ON (YES), the process proceeds to the next step 117, and if OFF (ON), the process proceeds to step 118 where the discrimination OFF signal is output to the discrimination control circuit 46 (7th step).
(discrimination routine shown in the figure) (indicated by an arrow), and drives the counting motor 19, pump motor 21, double feed detection lamp 37, and floodlight 4.
After stopping the lighting of 0 (step 181), step 182 in FIG. 6D is performed to perform normal termination processing.
Proceed to.

<Step 117> As in step 108, it is detected whether or not the rotary tube position sensor output signal (SNS) which is in the OFF state has reached the rising time when it is in the ON state.
If YES, proceed to the next step 118; if NO, return to step 116.

<Step 116> Similarly to step 109, a trigger signal (TRG) is output to the discrimination control circuit 46 (discrimination routine shown in FIG. 7) (indicated by an arrow), and a counter that counts the number of turned bills is output.
Add 1 to CNT (step 119) and return to step 110.

Next, control during batch processing (in the case of YES in step 115) will be explained with reference to the flow shown in FIG. 6B.

FIG. 6B <Step 120> As in step 180, a discrimination OFF signal is output to the discrimination control circuit 46 (discrimination routine shown in FIG. 7) (indicated by an arrow), and the process proceeds to the next step 121.

In addition, in the explanation of the steps after step 121 for performing batch processing in accordance with the number of sheets matching, detailed explanations will be given with reference to the state diagrams shown in FIGS. 11 and 12 and the time chart shown in FIG. 9. explain.

First, the situation at the time when the count value and the set value match will be explained.

When the set number of banknotes to be batch-processed is the banknote Sa shown in FIG.
At the point when the rotary cylinder position sensor output signal (SNS) rises after being detected by (Step 115).

As mentioned above, in the same way as when detecting abnormal banknotes,
If the rotation of the rotary tube 3 is suddenly stopped at this point,
Since the set number of banknotes Sa stops at the intermediate separation position shown in FIG. 12, the rotary tube 3 is allowed to continue rotating without immediately stopping suddenly, and its rotational position is monitored.

<Step 121> Turn on the rotary tube position sensor output signal (SNS).
The OFF state is monitored, and when it becomes OFF (YES), it proceeds to the next step 122, and when it becomes ON (NO), it waits at this step 121.

In addition, the time when it becomes OFF corresponds to the time when the set number of banknotes Sa reaches the position shown in FIG. 12, and if there is a set number of banknotes plus the first banknote, The plus first banknote is turned over to the position shown by banknote Sb in FIG. 12.

<Step 122> Rotating tube position sensor output signal (SNS) ON-
The OFF state is monitored, and if it is ON (YES), proceed to the next step 123, and if it is OFF (NO), it waits at step 122.

In addition, when it turns ON, it means the set number of banknotes.
This corresponds to when Sa reaches the position shown by banknote Sc in Figure 11, which coincides with the timing shown by timing Tm + 1 in Figure 9, and as before, the set number of banknotes plus the first banknote. If there is a banknote Sa, the first banknote is shown in Figure 11 as a banknote Sa.
It will be flipped to the position indicated by .

<Step 123> Then, at this timing Tm+1, the counting motor forward rotation drive signal (CMD-
Counting motor brake signal (CM−
BRK), the rotation of the rotary cylinder 3 in which the suction shaft 5 is arranged is suddenly decelerated, and the pump motor 21 is driven and the double feed detection lamp 3 is
7. Lighting of the floodlight 40 is stopped.

<Step 124> Turn on the rotary tube position sensor output signal (SNS).
The OFF state is monitored, and in a loop with the next step 125, it is determined whether the rotating barrel 3 has stopped while the rotating barrel position sensor output signal (SNS) remains in the ON state.

In other words, the rotary tube position sensor output signal (SNS)
is in the ON state (when step 124 is YES), it is determined in step 125 whether the ON state has continued for a certain period of time, and if it is NO that the certain period of time has not elapsed, the process is repeated with step 124. Waits in a loop, and if YES after a certain period of time,
It is determined that the rotary cylinder 3 has been stopped in the ON state, and the process proceeds to the next step 126 (timing Tm+ in Fig. 9).
2).

On the other hand, in the loop from step 124 to step 125, the ON state does not continue for a certain period of time and
If it is in the OFF state (step 124 is NO)
), proceed to step 133.

Note that the rotary cylinder position sensor output signal (SNS)
The case where the rotary cylinder 3 is able to stop while remaining ON corresponds to when the set number of banknotes Sa reaches the position shown by banknote Sc (Sd) in FIG. 12, and similarly to the above, If the set number plus the first bill exists, the plus first bill is the maximum number of 12th bills.
The banknote will be turned over to the intermediate separation position indicated by Sa in the figure.

Furthermore, the limited number plus the second banknote Sb shown in FIG. 12 is attracted to the suction shaft 5 for a short period of time due to the residual vacuum pressure inside the suction shaft 5, as shown in FIG. Although it is in a bent state, the banknote Sb's own strength causes it to immediately return in the direction of the arrow.

<Step 126> For batch processing, it is necessary to clearly separate the set number of banknotes and uncounted banknotes, and the set number of banknotes stopped at the intermediate separation position plus 1
A process is performed to return the th banknote Sa (FIG. 12) to the uncounted banknote Sb side.

That is, in this step 126, the timing
At Tm+3, a counting motor low speed reversal signal (CMD-R) is applied in place of the counting motor brake signal (CM-BRK) to start the counting motor 19 in reverse at a low speed.

Note that this reversal process is controlled by monitoring the ON-OFF state of the rotary cylinder position sensor output signal (SNS).

<Step 127> Rotating cylinder position sensor output signal (SNS) ON-
The OFF state is monitored, and if it is OFF (YES), proceed to the next step 128, and if it is ON (NO), it waits at step 127.

In addition, the time when it becomes OFF is the time when the banknote Sa shown in Figure 12
The set number of banknotes plus the first banknote is the first banknote.
This corresponds to when the bill is returned to the position indicated by Sa in Figure 1.

Also, at this time, the set number of banknotes Sc (Sd) is determined by the strength of the banknote itself, as shown in Figure 11.
It is not divided into two by the suction shaft 5 which is reversed as shown by Sc.

<Step 128> Rotating tube position sensor output position (SNS) ON-
The OFF state is monitored, and if it turns ON (YES), it proceeds to the next step 129, and if it turns OFF (NO), it waits at this step 128.

In addition, the time when it becomes ON corresponds to the time when the set number of bills returned to the position shown by banknote Sa in Figure 11 plus the first banknote is returned to the position shown by banknote Sb in Figure 12. This coincides with the timing indicated by timing Tm+4 in FIG.

Even if the rotation of the rotary cylinder 3 is stopped at this timing Tm+4, due to the strength of the banknote Sb itself, it will be mixed with other uncounted banknotes as shown by the arrow in Fig. 12. In order to bring them together, the rotating cylinder 3 continues to be reversed a little more.

<Step 129> Rotating tube position sensor output signal (SNS) ON-
The OFF state is monitored, and when it is OFF (YES), it proceeds to the next step 130, and when it is ON (NO), it waits at step 129.

In addition, the time when it becomes OFF is the time when the banknote Sb in Figure 12
This corresponds to when the set number of banknotes plus the first banknote returned to the position shown in Figure 11 is returned to the position shown by banknote Sb in Figure 11.
This coincides with the timing indicated by timing Tm+5 in the figure.

<Step 130> Batch processing is completed at this timing Tm+5, and the counting motor low speed reverse signal (CMD-R)
Counting motor brake signal (CM-BRK) instead of
is applied for a short time to stop the counting motor 19.

<Step 131> This message is output if a clearing operation has been performed to take out the set number of banknotes batch-processed as described above from holder 1, or if the batch process described later has ended in failure. While canceling the alarm, it is determined whether a clearing operation has been performed to take out the banknotes on the holder 1, and if YES, the process proceeds to the next step 132.

<Step 132> Open signal for holder 1 (according to step 132)
22) is output and this flow ends.

On the other hand, in step 124, a case in which the rotary cylinder position sensor output signal (SNS) does not remain ON for a certain period of time but becomes OFF midway will be explained in a similar manner.

First, if the rotary barrel position sensor output signal (SNS) turns OFF midway, if there is a set number of banknotes plus the first banknote, then the first banknote is This indicates that the banknote has been turned over beyond the intermediate separation position shown by banknote Sa to the position shown by banknote Sc or banknote Sb in FIG. 11, which indicates a failure in batch processing. .

In addition, the above-mentioned plus first banknote is the banknote shown in Figure 11.
It may be possible to perform the above-mentioned return process by stopping at the position indicated by Sc, but depending on the stiffness of the banknote, etc.
Since it was considered that the rotary cylinder position sensor output signal (SNS) would be moved to the position indicated by Sd, if the rotary cylinder position sensor output signal (SNS) becomes OFF midway, the process will proceed to the next step 133.

By the way, if the set number of bills plus the first bill exists, batch processing will fail, but if the number of bills loaded in the holder 1 happens to match the set number of bills, even if the rotating tube 3 suddenly stops. Even if a process fails or an overrun occurs, it cannot be said that batch processing has failed.

That is, the next step 133 is a step of determining whether or not the set number of banknotes plus the first banknote is present.

<Step 133> As explained in step 120 above,
When the set number of banknotes (indicated by banknote Sa in Figure 11) is counted and the number of banknotes matches, the set number plus the first banknote (indicated by banknote Sa in Figure 11) is counted.
Sb), a trigger signal (TRG) for discrimination has already been output to the discrimination control circuit 46 (discrimination routine shown in FIG. 7) (see step 118, indicated by the arrow in FIG. 9). Timing Tm).

As will be explained in detail later, when this trigger signal (TRG) is output, the discrimination result for the set number of banknotes indicated by banknote Sa in FIG. 11 is output (however, only in the case of an abnormality), 1st
Based on the reading of the set number of banknotes shown in Figure 1 banknote Sb plus the surface pattern of the first banknote, and this read data, it is determined whether or not a banknote exists, and only when there is no banknote, an end signal is issued. will be output.

Therefore, in this step 133, it is determined whether or not the end signal has been output from the discrimination control circuit 46 as shown by the arrow, and if YES, the step 133 is continued without outputting an alarm.
Proceed to step 131, and if NO, proceed to the next step 134.

Note that in order for the end signal to be output, it is necessary to be in the detection mode as described above, and in the case of mere counting, all cases are treated as batch failures.

<Step 134> If the batch processing fails as described above, or if an abnormal banknote is detected and cannot be separated into the intermediate separation position shown by banknote Sa in Figure 12 as described later, the batch is defective. An alarm is output to notify the operator using an abnormality lamp or buzzer, and the process proceeds to step 131.

Next, when an abnormal banknote is detected (step 113YES)
The control in case 2) will be explained focusing on the flow shown in FIG. 6C.

In addition, in the description of the steps after step 135, which performs the intermediate separation and stop operation (approximately equivalent to the batch operation) during the retry process or confirmation process associated with the detection of abnormal banknotes, the state description shown in FIGS. 11 and 12 will be used. This will be explained with reference to the drawings and time charts shown in FIGS. 13 and 14.

First, it is assumed that an abnormal banknote (indicated by banknote Sa in FIG. 11) is detected at timing T81 in FIG. 13.

Fig. 6C <Step 135> Similar to step 180 and step 120, discrimination
An OFF signal is output to the discrimination control circuit 46 (discrimination routine shown in FIG. 7) (indicated by an arrow), and the process proceeds to the next step 136.

<Step 136> Then, at this timing T81, as shown in Fig. 13, a counting motor brake signal (BRK) is given instead of the counting motor signal (CMD normal rotation), and the rotation of the suction shaft 5 is The rotation of the cylinder 3 is suddenly decelerated, and the drive of the pump motor 21 and the lighting of the double feed detection lamp 37 and the floodlight 40 are stopped.

<Step 137> As in steps 124 to 125 above, the ON-OFF state of the rotating cylinder position sensor output signal (SNS) is monitored, and in a loop with the next step 138, the rotating cylinder position sensor output signal (SNS) is monitored. It is determined whether or not the rotating cylinder 3 has stopped while remaining in the ON state.

In other words, the rotary tube position sensor output signal (SNS)
is in the ON state (when step 137 is YES), it is determined in step 138 whether the ON state has continued for a certain period of time, and if it is NO that the certain period of time has not elapsed, the process is repeated with step 137. Waits in a loop, and if YES after a certain period of time,
It is determined that the rotating cylinder 3 has been stopped in the ON state, and the process proceeds to the next step 139 (see the timing diagram in Figure 13).
T82).

On the other hand, in the loop from step 137 to step 138, the ON state does not continue for a certain period of time and
If it is in the OFF state (step 137 is NO)
), similarly to the case where step 124 is NO, the process proceeds to step 134 shown in FIG. A batch failure alarm is output to notify the operator using an abnormality lamp or buzzer, and the above steps are performed.
Proceed to 131.

Note that the rotary cylinder position sensor output signal (SNS)
The case where the rotary cylinder 3 is able to stop while remaining in the ON state means that the abnormal banknote Sa is reliably stopped in a state where it is separated from the counted banknotes Sc and Sd and the uncounted banknotes Sb, as shown in FIG. It represents something.

Note that the banknote Sb following the abnormal banknote Sa shown in FIG. 12 is absorbed and bent by the suction shaft 5 for a short time due to the residual vacuum pressure in the suction shaft 5 as shown in FIG. Although the banknotes are in
Due to the strength of his hips, the striker will be able to quickly return to the direction of the arrow.

<Step 139> In step 119, the counted value of the counter CNT is compared with the value of the counter R・CNT set at the time of retry (which is reset to 0 at the initial stage of counting), and a discrepancy is determined.
In the case of NO, the process proceeds to the next step 140, where the count value of the counter CNT is set to the counter R.CNT, and the process proceeds to step 141, and in the case of YES, the process proceeds to step 147.

In other words, for example, if the 45th bill is determined to be an abnormal bill for the first time, the values of both counters will be CNT
= 45, R CNT = 0, the values of both counters do not match, it is determined that this is the first abnormal banknote, and the process moves to retry processing, whereas when it is determined that the banknote is abnormal continuously. Since R·CNT=45 was set at the time of the previous abnormality detection, the values of both counters match and the process is prevented from proceeding to retry processing.

<Step 141> As explained in step 34 above, the first
In order to perform a retry process to automatically re-identify the abnormal banknote Sa separated and stopped at the position shown in Figure 2, the counting motor 19 is driven in reverse at low speed (timing T83 in Figure 13), and the two previous suction shafts are rotated. Rotary tube position sensor output signal (SNS) to set to start position
The ON-OFF state of the is monitored in steps 142 to 144 below.

<Step 142> That is, in this step 142, the ON-OFF state of the rotary cylinder position sensor output signal (SNS) is monitored, and when it becomes OFF (YES), the next step is started.
Proceed to 143 and if ON (NO), complete this step.
Wait at 142.

In addition, the time when it becomes OFF is the time when the banknote Sa shown in Figure 12
This corresponds to when the abnormal banknote indicated by is returned to the position indicated by banknote Sa in Figure 11,
This coincides with the timing indicated by timing T84 in FIG.

<Step 143> Rotating tube position sensor output signal (SNS) ON-
The OFF state is monitored, and if it turns ON (YES), the process proceeds to the next step 144, and if it turns OFF (NO), it waits at this step 143.

Incidentally, the time when it is turned on corresponds to the time when the abnormal banknote that was returned to the position shown by banknote Sa in FIG. 11 is returned to the position shown by banknote Sb in FIG. 12.

<Step 144> Rotating tube position sensor output signal (SNS) ON-
The OFF state is monitored, and when it is OFF (YES), it proceeds to the next step 145, and when it is ON (NO), it waits at step 144.

In addition, the time when it becomes OFF is the time when the banknote Sb in Figure 12
The abnormal banknote returned to the position indicated by is the 11th banknote.
This corresponds to when the banknote is returned to the position shown in the figure Sb, and this corresponds to the timing shown in Figure 13.
Matches the timing shown in T855.

<Step 145> At this timing T85, the return processing of the abnormal banknote Sa is completed, and the counting motor brake signal (BRK) is sent instead of the counting motor drive signal (CMD low speed reversal).
is applied for a short time to stop the counting motor 19.

<Step 146> When the abnormal banknote shown as banknote Sa in FIG. 12 is combined with uncounted banknotes as shown in banknote Sb in FIG. 11, the count value of counter CNT is corrected. , subtract 1.

That is, the abnormal banknote Sa has already been counted by the counter CNT in step 119, and if it is combined with uncounted banknotes, it will be counted twice during retry counting. The count value is corrected by subtracting 1.

Thereafter, the process returns to step 101 shown in FIG. and lights up the floodlight 40.

Then, in step 106, the output of the pressure judgment signal (VSW) is detected (13th
At timing T86 in the figure, the counting motor 19 starts to rotate in the normal rotation direction at high speed, and thereafter, at the rising time when the rotating tube position sensor output signal (SNS) turns ON, the trigger signal (TRG) and counting signal (CNT) are output.
is output, and the banknote flipping and denomination determination operation from the point of interruption is automatically restarted.

On the other hand, as explained in step 139 above, a case will be explained in which the same banknote is consecutively determined to be an abnormal banknote.

First, at timing T101 in FIG. 14, an abnormal banknote (indicated by banknote Sa in FIG. 11) is detected, and at timing T102, the abnormal banknote Sa is detected as the first banknote.
Assume that the device is stopped in the separated state as shown in Figure 2.

<Step 147> As shown in Fig. 12, the abnormal banknote Sa is stopped at a position relatively close to the counted banknotes Sc and Sd, so it may be difficult for the operator to visually check it. Yes, this step 147
In the following, in order to solve this problem, the rotary cylinder 3 is reversed from the separation stop state shown in FIG. 12 to the banknote Sa position shown in FIG.

That is, at timing T103 in FIG.
A counting motor drive signal (CMD low speed reverse rotation) is given to the counting motor 19 in place of the counting motor brake signal (BRK) to drive the rotary cylinder 3 in reverse at a low speed.

<Step 148> Rotating tube position sensor output signal (SNS) ON-
The OFF state is monitored, and if it is OFF (YES), proceed to the next step 149, and if it is ON (NO), it waits at step 148.

In addition, the time when it becomes OFF is the time when the banknote Sa shown in Figure 12
This corresponds to the time when the abnormal banknote shown by is returned to the position shown by the banknote Sa in FIG. 11, and this corresponds to the timing shown by timing T104 in FIG. 14.

<Step 149> At this timing T104, counting motor 1
Counting motor drive signal for 9 (CMD low speed reverse)
The output is stopped, and a counting motor brake signal (BRK) is applied for a short time instead to stop the reverse rotation of the rotary cylinder 3, and at timing T105, a counting motor brake signal (BRK) is applied to the counting motor 19 instead. A counting motor drive signal (CMD low-speed forward rotation) is applied to drive the rotary cylinder 3 in low-speed forward rotation.

<Step 150> Rotating tube position sensor output signal (SNS) ON-
Monitor the OFF state, and when it becomes ON (YES), proceed to the next step 151 (timing T106 is reached).
If it is OFF (NO), it waits at step 150.

<Step 151> At timing T106, the output of the counting motor drive signal (CMD low speed forward rotation) to the counting motor 19 is stopped, and instead, the counting motor brake signal (BRK) is applied for a short time to cause the rotating cylinder 3 to rotate forward. This corresponds to when the abnormal banknote shown by banknote Sa in FIG. 11 is moved from approximately this position to the position shown by banknote Sa in FIG. 1.

In this state, the operator confirms what has been determined to be the abnormal banknote Sa.

<Step 152> Determine whether or not the current mode is the amount calculation mode. If YES, proceed to the next step 153; if NO, proceed to step 165.

<Step 153> The abnormal banknote Sa is placed at the intermediate separation position shown by banknote Sa in Figure 1 (both uncounted banknotes Sb and counted banknotes Sc and Sd).
In the suspended state where the banknote is separated and stopped at a position far away from the banknote, the operator visually confirms the denomination of the abnormal banknote Sa, and presses the denomination button corresponding to the denomination of the abnormal banknote Sa in this step 153. It is determined whether the 10,000-ticket button has been operated, and if YES, similarly to step 216 in the determination processing flow described later,
A code representing the ten-thousand ticket is set (set a flag: step 154), and if NO, proceed to the next step 155.

<Step 155> As in step 153, it is determined whether the 5,000-note button has been operated, and if the answer is YES, a code representing the 5,000-note button is set (step 156), and if the answer is NO, the next step is executed. Proceed to 157.

<Step 157> As in steps 153 and 155 above, determine whether the 1,000-note button has been operated, and if YES, set a code representing 1,000-notes (step 158), and if NO, proceed to the next step. Proceed to 159.

<Step 159> In any of the above steps 153, 155, and 157, it is determined whether the denomination code for the abnormal banknote Sa has been set. If YES, proceed to the next step 160; if NO, proceed to step 160. Proceed to step 161.

<Step 160> After setting the denomination code for the abnormal bill Sa, it is determined whether or not a confirmation button has been operated. If YES, proceed to step 163; if NO, proceed to the next step 161. move on.

<Step 161> If the visually confirmed abnormal banknote Sa is a double-adsorbed banknote, or if it is a sheet of paper such as a receipt that has been sandwiched between banknotes, this A clear operation is necessary to remove the
Similarly, determine whether the clear button is operated or not,
If YES, the process advances to step 162 to end the counting operation, and if NO, the process returns to step 153 so that the denomination code for the abnormal banknote Sa can be input.

<Step 162> Similar to step 132, an open signal (see step 22) to the holder 1 is output, and this flow ends.

<Step 163> On the other hand, in step 160, the abnormal banknote Sa
When the denomination code for the banknote is set and its confirmation operation is performed, the set denomination code is output in the same manner as step 216 in the discrimination processing flow described later, and in the next step 164, when the next abnormal banknote is detected, the denomination code is output. 6A, the pump motor 21 is started to be driven, and in step 105, the discrimination ON signal ( and front/back mode signal), and at the same time, the double feed detection lamp 37 and the floodlight 40 are turned on.

Then, in step 106, when the output of the pressure judgment signal (VSW) is detected, the counting motor 19 starts to rotate at high speed in the normal rotation direction, and thereafter, the rotary cylinder position set output signal (SNS) is in the ON state. At the rising edge of the trigger signal (TRG)
and a counting signal (CNT) are output, and the banknote flipping and denomination discrimination operation from the point of interruption is automatically restarted.

<Step 165> In step 152, if the current mode is other than the amount calculation mode, that is, when an abnormal banknote is detected in the different denomination detection mode, the abnormal banknote has already been turned over and counted. It is confirmed whether the banknote is of the same denomination as the banknote in question, and if it is confirmed that the banknote is of the same denomination as YES, the same steps as in steps 146 and 163 are carried out.
Returning to step 101 shown in FIG. 6A, the operation of turning over the banknotes and determining the denomination from the point of interruption is automatically resumed, and in the case of NO, the next step 166 is performed. Proceed to.

<Step 166> As in steps 131 and 161, it is determined whether the clear button has been operated or not, and it is confirmed that the abnormal banknote is a banknote of a different denomination and the clear button has been operated.
If YES, proceed to step 162, output an open signal for holder 1 (see step 22), and end this flow; if NO, return to step 165, and proceed to steps 165 to 165.
Waits in the loop at step 166.

In addition, in the flow shown in FIG. 6C,
It is explained that only a confirmation input can be made for one bill, and it may be thought that the only way to process this is to perform a clear operation in the case of double adsorption detection, but in the case of the present invention, double Since the suction banknotes can also be set to be separated and stopped at the intermediate separation position shown in FIG. 12 or FIG. 1, the number (and denomination composition) of double suction banknotes can be confirmed, It is also possible to configure the system so that the number of sheets data (and the denomination code for the number of sheets) can be input at the time of confirmation.

In this case, since the double-adsorbed banknote Sa itself has already been counted as one by the counter CNT, the data obtained by subtracting 1 from the input number of banknotes data is added to the counter CNT.

Furthermore, since all the input denomination codes are valid, they are used as they are for amount counting.

Next, as explained in step 111 or step 116 of FIG. 6A, FIG. The explanation will be based on the flow shown.

Note that this flow shows the flow at the end of counting in a mode other than the batch mode described above.

<Step 182> Determine whether or not the detection mode switch 53 is turned on. If YES, proceed to the next step 183.
If NO, proceed to step 188.

<Step 183> Similarly to step 133, if the end signal (indicated by the arrow) has not been input from the discrimination control circuit 46 (discrimination routine shown in FIG. 7) for a certain period of time (step 184), For example, if the suction shaft 5 does not pick up the banknotes even though banknotes to be counted have been set, a flag indicating a residual error is set in a predetermined area of the storage unit (RAM 48). After (step 185),
Proceed to the next step 186.

Further, if an end signal is input, the process advances to step 188.

<Step 186> In the same manner as in step 131, step 161, or step 166, it is determined whether the clear button has been operated or not, and the clear button is pressed to reset the residual error or to reset the discrepancy error described later. If the operation is YES, the program proceeds to step 187, outputs an open signal to the holder 1 (see step 22 above), and ends this flow; if the operation is NO, the program waits in step 186.

<Step 188> If the current mode is not the detection mode in the step 182, or if the input of the end signal is confirmed in the step 183, an error occurs when counting and determining the banknotes loaded in the holder 1. If the process is completed without any occurrence, it is determined whether the mode setting is set to the number of sheets check mode, and if YES, the process proceeds to the next step 189, and if NO, the process proceeds to step 193.

<Step 189> The number of banknotes counted as above is
Determine whether it matches the preset number of sheets, and if YES, proceed to the next step 190.
At the same time, in the case of no match, a flag indicating a mismatch error is set in a predetermined area of the storage unit (RAM 48) (step 191).
Proceed to step 186 above.

<Step 190> Furthermore, it is determined whether the mode setting is set to the stamping mode, and if YES, the stamping solenoid 30C (or 31C) is operated,
Stamp the seal (step 192), and if NO, proceed to the next step 193.

<Step 193> Determine whether or not the mode setting is set to addition mode. If YES, add the counting results of the previously counted bills and store the addition result in the storage unit (RAM 48). (step 194), and if NO, proceed to the next step 195.
Proceed to.

<Step 195> Determine whether or not the mode setting is set to amount counting mode. If YES, display the total amount of counted bills (Step 196), and if NO, display Proceed to step 187 above.
Open signal for holder 1 (step 22 above)
) and exit this flow.

In addition, in the amount counting mode, the step
Although it has been explained that the total amount is displayed in step 196, when the counter CNT in step 119 shown in FIG. It is also possible to calculate and display the total amount.

Next, the contents of the program stored in the ROM 64 of the discrimination control circuit 46 will be explained with reference to FIGS. 7 and 8.

Figure 7 <Step 200> Start of determination routine <Step 201> Determine whether or not the trigger signal (TRG) (indicated by the arrow) has been input from the counting routine, and YES
In this case, proceed to the next step 202.

<Step 202> It is determined whether or not the discrimination ON signal (indicated by the arrow) has been input from the counting routine. If NO, the process returns to step 201. If YES, the analog switch 80 shown in FIG. 4 is activated. Select the output of the light receiving element 38 of the double feed detection sensor to the amplifier 7.
8. Working through the A/D converter 73,
After storing it in the RAM 65 (step 203), the process advances to step 204.

<Step 204> Step 215, step 223, and step described later
Based on the error code set in 232,
Determine whether there is a mixture of different denominations, a discrepancy between the front and back sides, a discrimination error (abnormal banknotes are mixed),
If YES, an error signal and an error code are output, and the error details are displayed on the display section 63 (step 205), after which the process returns to step 201.

Note that the error signal output in step 205 is
As indicated by the arrow, step 113 of the counting routine of FIG. 6A is provided.

If NO, there is no mix-up of different denominations, no discrepancy between the front and back sides, and no discrimination abnormalities, the process proceeds to the next step 206.

Note that when the first trigger signal (TRG) is output, steps 215, 222, and 232 have not been passed and no determination has been made, so the first step 204 is always NO and the process proceeds to step 206.

<Step 206> Based on the detection data taken in from the light receiving element 38 of the double feed detection sensor in step 203 and the double comparison level serving as the discrimination standard set in step 218 (described later), the bill is double adsorbed. It is determined whether or not the error has been made, and if YES, an error signal and an error code are output, and the content of the error is displayed on the display section 63 (step 207), after which the process returns to step 201.

Note that the error signal output in step 207 is
As indicated by the arrow, step 113 of the counting routine of FIG. 6A is provided.

In addition, it was determined that no double adsorption occurred.
If so, proceed to the next step 208.

Note that, similarly to step 204, when the first trigger signal (TRG) is output, the banknote Sa for which double adsorption should be determined does not exist at the position shown in Figure 1, and the reference double comparison level is Since it has not been set, the first step 206 is always NO and the process proceeds to step 208.

<Step 208> Select the analog switch 79 shown in FIG.
By storing the output of the area sensor 34 in the RAM 65 via the amplifier 72 and the A/D converter 73, area data in the area E (data on the N line) is captured.

Note that this area data is taken in based on the flow shown in FIG.

That is, when a capture signal is output (step 300), after setting Y to 0 and X to 0 (step 301), the process proceeds to the next step 302.

Then, in this step 302, the required N
It is determined whether or not the output of line data (area data) has been completed, and if YES, a determination start signal is output (step 303), and the process returns to the main routine of FIG.

Also, if NO in step 302,
Steps 304 to 311 are looped until the specified N lines of data are output at step 312, and at the point when the data is output, the process proceeds to step 303 as described above.

When the line-by-line acquisition of area data is completed in this manner, the process proceeds to the next step 209 shown in FIG.

<Step 209> Determine whether the data captured in step 208 is of a level that does not have a pattern (that is, whether it is a black pattern on the surface 1b of the holder 1), and select YES (no data). If so, after outputting the end signal (step 210),
Return to step 201.

The end signal output at step 210 is supplied to step 133 in FIG. 6B or step 183 in FIG. 6D, as indicated by the arrow.

Furthermore, if the captured area data is of a level having a pattern (NO), the process advances to the next step 211.

<Step 211> Determine whether the setting mode is set to amount calculation mode, and if YES, determine which denomination of each bill is loaded into the holder 1. If yes, proceed to step 213, and if NO, proceed to the next step 212.

<Step 212> It is determined whether or not the bill attracted by the suction shaft 5 is the first one. If YES, proceed to step 213; if NO, proceed to step 230.

<Step 213> Based on the area data of the first bill imported in step 208, the standard of the current 3 denominations (L denominations) totaling 12 patterns (4 x L patterns) stored in the ROM64 After comparing the data (for one denomination, there are four patterns of front and back, forward and reverse), the process proceeds to the next step 214.

<Step 214> As a result of comparing the area data of the first banknote with the reference data of the 12 patterns, it is determined whether there is a matching pattern, and if NO, it is determined that the banknote is an abnormal banknote that cannot be identified. As the storage unit (RAM
A flag indicating a discrimination abnormality is set in a predetermined area of step 65) (step 215), and the process returns to step 201.

Also, if there is a matching pattern (YES),
A flag indicating that the identified banknote is one of the three denominations is set in a predetermined area of the storage unit (RAM 65) (step 216), and a flag indicating the front and back sides of the banknote is set (step 216). After step 217),
Based on the determined denomination and front/back information, ROM6
After setting the double comparison level, which is the discrimination criterion for double adsorption stored in step 4, in the storage section (RAM 65) (step 218), the process proceeds to step 219.

As described above, in the amount calculation mode, the counting control circuit 45 automatically calculates the total amount of the flipped bills at any time based on the denomination code output in step 216, and also performs this calculation. The results can also be displayed at any time on the display section 63 as described above.

<Step 230> On the other hand, if it is determined in step 212 that the bill attracted by the suction shaft 5 is not the first bill, the area data of the bill taken in in step 208 and the data stored in the ROM 64 are specified denomination (denomination set in step 216)
The process proceeds to the next step 231 after comparing only four patterns of reference data, front and back, forward and reverse.

<Step 231> As a result of comparing the area data of the banknote with the reference data of the four patterns, it is determined whether there is a matching pattern, and if NO, this banknote is a banknote of a different denomination (strictly speaking, There may also be banknotes with abnormal identification)
Assuming that the
232), return to step 201.

Also, if there is a matched pattern (YES)
As mentioned above, a flag indicating the front and back sides of the banknote is set in a predetermined area of the storage unit (RAM 65) (step 217), and further, in step 218, the banknote is double-adsorbed in a predetermined area of the storage unit (RAM 65). A double comparison level, which is a discrimination criterion, is set, and the process proceeds to the next step 219.

<Step 219> Determine whether or not the front/back mode switch 54 is turned on. If NO, return to the switch 201, and if YES, proceed to the next step 202.
Proceed to.

〈Step 220〉 Determine whether this banknote is the first one, and select NO.
If YES, proceed to step 222; if YES, proceed to the next step 221.

<Step 221> The front and back codes of the first banknote set in step 217 are set in the storage unit (RAM 65) as front and back reference data, and based on this front and back reference data, the front and back of the banknotes are thereafter determined (step 221). 222).

<Step 222> The front and back codes set in step 217 are compared with the front and back reference data set in step 221 to determine whether the second and subsequent banknotes match the front and back of the first banknote. If they match (YES), the process returns to step 201, and if they do not match (NO), in the next step 223, the two sides are stored in a predetermined area of the storage unit (RAM 65). After setting the flag indicating that
~Repeat step 232.

Note that the timing for capturing the trigger signal (TRG), double data, etc. described above is shown in the timing chart in FIG.

When these trigger signals (TRG) and the timing of capturing double data correspond to the steps in FIG. 7, the discrimination trigger signal corresponds to step 201, and the timing of capturing double data corresponds to step 203. Hereinafter, the error check timing corresponds to step 204, the double check timing corresponds to step 206, the area data import timing corresponds to step 208, and the end check timing corresponds to step 209.
Discrimination processing timing is from step 211 to step 214
Further, the denomination, front and back, double comparison level, and error set timing correspond to steps 216 to 218, step 215, step 223, and step 232, respectively.

In addition, in this determination processing flow, when determining the denomination of the second and subsequent coins when the mode is not in the amount calculation mode, that is, when both steps 211 and 212 are NO, only the different denomination code can be output as the error code. Immediately before step 232 of this discrimination processing flow, a comparison is made with the remaining eight patterns to determine whether or not there is a matching pattern, and if there is a matching pattern, it is left as is. Proceed to step 232 to set the different denomination code, and if there is no matching pattern, proceed to step 232.
It is also possible to proceed to 215 and set a discrimination error code.

As described above in detail, according to the first invention, the number of paper sheets turned over by the suction shaft is set to a preset number plus 1.
When the number of sheets is reached, the rotation of the rotary tube is suddenly stopped and the operation of turning over subsequent sheets is interrupted, and the set number of sheets plus the first sheet is not counted by the suction shaft. It is stopped at an intermediate separation position away from the paper sheets and the counted paper sheets, and at the same time, the supply of vacuum pressure to the suction shaft is stopped.

Then, for the set number of sheets plus the first sheet that is stopped at an intermediate separation position that is far away from both uncounted sheets and counted sheets, the rotary cylinder in the stopped state moves in the opposite direction to the one at the time of counting. By being rotated by a predetermined angle, the paper sheets are returned together with the uncounted paper sheets, and the so-called batch operation is completed.

Next, the second invention will be described based on the flow shown in FIG. 15 and with reference to state diagrams shown in FIGS. 11 and 12.

Note that the flow shown in FIG. 15 showing this second invention is replaced with the flow shown in FIG. 6B in the above-described first invention.

FIG. 15 (Step 400) As in step 120, the count value and the set value match, leading to this step 400.
A determination OFF signal is output and the process advances to the next step 401.

<Step 401> A brake signal is applied to the counting mode 19, and the rotation of the rotary cylinder 3 in which the suction shaft 5 is disposed is suddenly decelerated, and the pump motor 21 is driven and the double feed detection lamp 37 is activated. Lighting of the projector 40 is stopped.

<Step 402> Rotating tube position sensor output signal (SNS) ON-
The OFF state is monitored, and in a loop with the next step 403, it is determined whether the rotating barrel 3 has stopped while the rotating barrel position sensor output signal (SNS) remains in the ON state.

In other words, the rotary tube position sensor output signal (SNS)
is in the ON state (when step 402 is YES), it is determined in step 403 whether the ON state has continued for a certain period of time, and if the answer is NO that the certain period of time has not elapsed, the process is repeated with step 402. Waits in a loop, and if YES after a certain period of time,
It is determined that the rotary cylinder 3 can be stopped in the ON state, and the process proceeds to the next step 404.

On the other hand, in the loop from step 402 to step 403, the ON state does not continue for a certain period of time and
If it is in the OFF state (step 402 is NO)
), proceed to step 416.

Note that the rotary cylinder position sensor output signal (SNS)
The case where the rotary tube 3 is able to stop while remaining in the ON state corresponds to the case where the set number of banknotes has stopped at the position in front of the banknote Sa shown in FIG.

<Step 404> This state in which the set number of banknotes has stopped at the position shown by banknote Sa in FIG. 12 is referred to as B-1.

<Step 405> Similar to step 133, it is determined whether the end signal has been output, and if NO, it is assumed that the set number of bills plus the first bill Sb is present, and the next step 406 is performed. If YES, proceed to step 407.

Note that in order for the end signal to be output, it is necessary to be in the detection mode as described above, and in the case of mere counting, the process proceeds to the next step 406.

<Step 406> Determine whether the vacuum pressure inside the suction shaft 5 has decreased and approached atmospheric pressure (NAP-ON). If YES, proceed to the next step 407; if NO, proceed to this step. Wait on 406.

Note that approaching the atmospheric pressure means that the set number of banknotes plus the first banknote Sb shown in FIG. 12 approaches the pressure shown in FIG. This indicates that Sb uses his own hip strength to return in the direction of the arrow.

<Step 407> It is determined whether or not the batch operation is in the B-1 state (a state in which the set number of banknotes is stopped at the position shown by banknote Sa in FIG. 12), and if YES, the next step is performed. Proceed to 408, if NO, step
Proceed to 421.

<Step 408> Set number of banknotes (indicated by banknote Sa in Figure 12)
In order to send the counted banknotes to the banknotes Sc and Sd,
The counting motor 19 is driven to rotate forward at low speed.

<Step 409> Rotating tube position sensor output signal (SNS) ON-
The OFF state is monitored, and when it is OFF (YES), the process proceeds to the next step 410, and when it is ON (NO), it waits at step 409.

In addition, the time when it becomes OFF corresponds to when the set number of banknotes passes the position shown by banknote Sa in FIG. 12.

<Step 410> Rotating tube position sensor output signal (SNS) ON-
The OFF state is monitored, and if it turns ON (YES), it proceeds to the next step 411, and if it turns OFF (NO), it waits at this step 410.

Note that the time when the result is NO corresponds to when the set number of banknotes has passed the position indicated by banknote Sc in FIG. 11.

<Step 411> Rotating tube position sensor output signal (SNS) ON-
The OFF state is monitored, and if it is OFF (YES), proceed to the next step 412, and if it is ON (NO), it waits at step 411.

In addition, the time when it becomes OFF corresponds to the time when the set number of banknotes has reached the position shown by banknote Sc in FIG. 12.

<Step 412> Rotating tube position sensor output signal (SNS) ON-
The OFF state is monitored, and if it turns ON (YES), the process proceeds to the next step 413, and if it turns OFF (NO), it waits at this step 412.

In addition, when it becomes ON, it corresponds to the time when the set number of banknotes has reached the position shown by banknote Sd in Figure 11, and the suction shaft 5 is set to the standby position shown in Figure 1. corresponds to

<Step 413> At this point, the forward rotation of the counting motor 19 is stopped.

<Step 414> This message is output when a clearing operation is performed to take out the set number of banknotes batch-processed as described above from holder 1, or when the batch process described later ends in failure. While canceling the alarm, it is determined whether a clearing operation has been performed to take out the banknotes on the holder 1, and if YES, the process proceeds to the next step 415.

<Step 415> Open signal for holder 1 (step 415)
22) is output and this flow ends.

On the other hand, a case will be described in which, in step 402, the rotary cylinder position sensor output signal (SNS) does not remain in the ON state for a certain period of time, but becomes OFF in the middle.

<Step 416> First, when the rotary barrel position sensor output signal (SNS) turns OFF midway, it means that the set number of banknotes has been turned over beyond the position indicated by banknote Sa in Figure 12. In a loop between this step 416 and the next step 417, it is determined whether the set number of banknotes has been turned over to the position indicated by banknote Sc in FIG.

In other words, the rotary tube position sensor output signal (SNS)
is in the OFF state (if step 416 is YES),
In step 417, it is determined whether the OFF state has continued for a certain period of time, and if the judgment is NO that the certain period of time has not elapsed, the process waits in a loop with step 416, and if the judgment is YES that the certain period of time has elapsed. Then, it is determined that the rotary cylinder 3 has stopped in the OFF state, and the process proceeds to the next step 418.

On the other hand, in the loop from step 416 to step 417, if the OFF state does not continue for a certain period of time and the state becomes ON midway, (step
If 416 is NO), proceed to step 430.

<Step 418> This state in which the set number of banknotes is stopped between the position shown by banknote Sa in FIG. 12 and the position shown by banknote Sc in FIG. 11 is referred to as B-2.

<Step 419> Similarly to step 405, it is determined whether the end signal has been output, and if NO, it is assumed that the set number of bills plus the first bill Sb is present, and the process proceeds to step 406. Wait until the pressure inside the suction shaft 5 approaches atmospheric pressure, and then proceed from step 407 to step 421.

On the other hand, in the case of YES, the process proceeds to the next step 420.

<Step 420> The case where the end signal is output indicates that the set number plus the first banknote Sb does not exist, and the set number of banknotes is placed on the counted banknotes Sc and Sd side. In order to perform the sending process, the counting motor 19 is driven in normal rotation at a low speed, and the step 410 is performed.
Proceed to.

<Step 421> On the other hand, in the batch in the B-2 state, the set number of bills plus the first bill Sb is in a state of being sandwiched between the two suction shafts 5, 5 as shown by bill Sa in FIG. In the following steps 421 to 429, a feeding operation for a set number of banknotes to the counted banknote side and an operation for returning the set number of banknotes plus the first banknote to the uncounted banknote side are performed.

First, the counting motor 19 is driven in normal rotation at a low speed in order to feed a set number of banknotes to the counted banknote side.

<Step 422> Rotating cylinder position sensor output signal (SNS) ON-
The OFF state is monitored, and if it turns ON (YES), the process proceeds to the next step 423, and if it turns OFF (NO), it waits at this step 422.

In addition, the time when it becomes ON corresponds to when the set number of banknotes passes the position shown by banknote Sc in Figure 11, while the set number plus the first banknote is at banknote Sa in Figure 11. This corresponds to passing the indicated position.

<Step 423> Rotating tube position sensor output signal (SNS) ON-
The OFF state is monitored, and when it is OFF (YES), the process proceeds to the next step 424, and when it is ON (NO), it waits at step 423.

In addition, the time when it becomes OFF corresponds to the set number of banknotes reaching the position shown by the banknote Sc in Figure 12, while the set number plus the first banknote reaches the position shown by the banknote Sa in Figure 12. This corresponds to passing the indicated position.

<Step 424> At this point, the forward rotation of the counting motor 19 is stopped, and then the counting motor 19 is driven in the reverse direction at a low speed in order to return the set number of bills plus the first bill to the uncounted bill side. .

<Step 425> At the beginning of this reversal, after the rotary cylinder position sensor output signal (SNS) turns ON (this step
425YES), hereafter, steps 127 to 127
By going through steps 426 to 428 similar to step 129, the set number plus the first banknote is returned to the uncounted banknote side, and in step 429, the reverse rotation of the counting motor 19 is stopped.

Then, the process proceeds to step 414, where after the clearing operation, an open signal to the holder 1 is output, and this flow ends.

Furthermore, a case will be described in which, in step 416, the rotary cylinder position sensor output signal (SNS) does not remain in the OFF state for a certain period of time, but instead becomes the ON state in the middle.

<Step 430> First, if the rotary barrel position sensor output signal (SNS) turns ON midway, it means that the set number of banknotes has been turned over beyond the position indicated by banknote Sc in Figure 11. It indicates that the
In the loop between this step 430 and the next step 431, the set number of banknotes are further transferred to the banknotes shown in FIG.
Whether it has been turned over to the position indicated by Sc, or
The set number of bills plus the first bill is shown in Figure 12.
It is determined whether the page has been turned over to the position indicated by Sa.

In other words, the rotary tube position sensor output signal (SNS)
is in the ON state (when step 430 is YES), it is determined in step 431 whether the ON state has continued for a certain period of time, and if the answer is NO that the certain period of time has not elapsed, the process is repeated with step 430. Waits in a loop, and if YES after a certain period of time,
In this ON state, it is determined that the rotary cylinder 3 has stopped, and the process proceeds to the next step 432.

On the other hand, in the loop from step 430 to step 431, if the ON state does not continue for a certain period of time and becomes OFF midway (step 430
is NO), proceed to step 439. 〈Step
432> This state in which the set number plus the first banknote stops between the position shown by banknote Sa in FIG. 11 and the position shown by banknote Sa in FIG. 12 is referred to as B-3.

In this case, the set number of banknotes is set at the position shown by banknote Sd in FIG. 11 or at the position shown by banknote Sc in FIG. 12 due to its stiffness.

<Step 433> As in steps 405 and 419, it is determined whether the end signal has been output, and if NO, it is assumed that the set number of bills plus the first bill Sb is present, and the next bill is Proceeding to step 434, only the operation of returning the set number of banknotes plus the first banknote to the uncounted banknote side is performed.

Also, if the end signal is output,
Since the returning operation is no longer necessary, the process proceeds to step 414, where after the clearing operation, an open signal to the holder 1 is output, and this flow ends.

<Step 434> The counting motor 19 is driven in reverse at a low speed in order to return the set number of bills plus the first bill to the uncounted banknote side.

<Step 435> Rotating cylinder position sensor output signal (SNS) ON-
Monitor the OFF state and perform steps 127 to 127 above.
By going through steps 435 to 437 similar to step 129, the set number plus the first banknote is returned to the uncounted banknote side, and in step 438, the reverse rotation of the counting motor 19 is stopped.

Then, the process proceeds to step 414, where after the clear operation, an open signal to the holder 1 is output, and this flow ends.

<Step 439> As in steps 405, 419, and 433, it is determined whether the end signal has been output, and if YES, there is no error in the batch status and no return operation is necessary. Assuming that (step
440), proceed to step 414, and after the clear operation,
An open signal for holder 1 is output, and this flow ends.

In addition, in the case of NO, the set number of bills plus the first bill passes the position shown by bill Sa in Fig. 12,
Since there is a high possibility that the batch processing has failed, a batch failure alarm is output (step 441), and the operator is notified by an abnormality lamp or buzzer, and is instructed to proceed to step 414. Make it.

As described above in detail, according to the second invention, when the number of sheets turned up by the suction shaft reaches a preset number, the rotation of the rotary tube is performed. is suddenly stopped and the subsequent sheet turning operation is interrupted, and the set number of sheets is separated by the suction shaft from uncounted sheets and counted sheets. At the same time, the supply of vacuum pressure to the suction shaft is stopped.

After the vacuum pressure of the suction shaft is no longer applied, the set number of sheets is stopped at the intermediate separation position, which is far away from both the uncounted sheets and the counted sheets. By further rotating the rotary cylinder by a predetermined angle in the forward direction from the time of counting, the sheets are collected together with the sheets that have already been counted, completing a so-called batching operation.

"Effects of the Invention" As explained in detail above, according to the first invention or the second invention, conventionally, after counting the desired number of paper sheets, by operating the separator, the subsequent Batch processing, which was previously performed by blocking the turning and counting operation of paper sheets, can be achieved without using a separator, so for example, in the case of banknotes that are damaged and easily cut, such as circulation tickets, This has the effect that there will be no breakage between the area pressed by the separator and the area sucked by the suction shaft.
