The flow of banknotes transported inside the banknote stacking apparatus will be described with reference to FIG. FIG. 1 is an explanatory diagram simply showing an arrangement configuration inside the banknote stacking apparatus. First, a plurality of banknotes 61 having different banknote lengths are set in the banknote insertion slot 51 provided in the banknote stacking apparatus 1 for stacking.

The roller 11a provided on the transport path 10 inside the banknote stacking apparatus 1 takes in banknotes from the banknote insertion slot 51 into the transport path 10 inside the banknote stacking apparatus, and transfers the banknotes captured in units of one sheet to the transport path 10.

A plurality of banknotes 63 having different banknote lengths are stacked in a good state in the banknote stacking port 52 with the banknotes accommodated therebetween.

Next, the schematic configuration inside the banknote stacking device will be described with reference to FIG. FIG. 2 is a block diagram showing a schematic configuration inside the banknote stacking apparatus of the present embodiment. The banknote stacking apparatus 1 shown in FIG. 2 is a control unit that controls the transport path 10 that transports banknotes, a banknote length acquisition section 20 that acquires banknote length, an impeller 30 that stacks banknotes, and the entire banknote stacking apparatus 1. 40.

The conveyance path 10 includes a conveyance mechanism 11 such as a roller that conveys banknotes on the conveyance path 10 and a conveyance driving unit 12 such as a motor that drives the roller.

The transport mechanism 11 is constituted by, for example, a roller and a belt that connects the rollers, and rotates when the transport driving unit 12 is driven to transport bills on the transport path 10.

The conveyance drive unit 12 is constituted by, for example, a stepping motor, and fluctuates the rotation speed of the conveyance mechanism 11 by performing drive control stepwise by the control unit 40.

The banknote length acquisition unit 20 stores in advance a sensor mechanism 21 that reads a banknote, a denomination identification unit 22 that identifies a denomination of a banknote by reading the banknote, and a banknote length corresponding to the denomination and the denomination, The bill length management memory 23 manages the length of the paper sheet, and the bill length corresponding to the denomination is acquired from the bill length management memory 23.

The sensor mechanism 21 includes, for example, a sensor that detects a banknote image and a timing sensor that detects the passage timing of the banknote on the transport path 10, and identifies the denomination of the banknote in the banknote length acquisition unit 20. Bill information and passage timing that can be detected.

The denomination identifying unit 22 identifies the denomination of the banknote based on the banknote information that can be identified by the sensor mechanism 21.

The impeller 30 includes an impeller mechanism 31 such as a rotating shaft of the impeller and the impeller 30, a rotation driving unit 32 that drives the impeller mechanism 31, and a blade tip position detection unit 33 that detects the position of the rotating blade tip. have.

The impeller mechanism 31 includes, for example, a plurality of blades, a rotating shaft, a disk for detecting a tip position of a blade tip (described later) provided on the rotating shaft, and the like. The bills are sequentially accommodated between the blades adjacent to the impeller 30, and the bills accommodated between the adjacent blades are sequentially accumulated.

The rotation drive unit 32 is constituted by, for example, a stepping motor, and the stepping motor is driven in proportion to the transmitted pulse power amount when sending pulse power that can change rapidly in a short time. Is. As a result, the stepping motor freely changes the rotation speed of the motor in a short time according to the amount of pulse power.

Further, the stepping motor is interlocked with the rotation shaft of the impeller 30, and when the rotation is driven, the impeller 30 is rotationally driven in synchronization and the rotational speed of the impeller 30 is also changed.

The blade tip position detection unit 33 is constituted by, for example, a sensor that detects the tip position of each blade, which will be described later. In order to control the tip of a bill to enter the central portion between adjacent blades, the impeller 30 to detect the tip position of each blade.

Here, the disk and sensor for detecting the tip position of the blade 31a will be described in more detail with reference to FIG. FIG. 3 is an explanatory diagram simply showing the arrangement of the disk and blade tip position detector 33 provided in the shaft portion of the impeller 30.

As shown in FIG. 3, on the disk 31b provided in the shaft portion of the impeller 30, elongated slits 311b are engraved radially at the same number and the same interval as the blades 31a provided in the impeller 30, and the position of the slit 311b And the position of the blade 31a correspond one to one.

The sensor includes a light emitting element 33a that irradiates light on one surface of the disk 31b on one side and a light receiving element 33b that receives light from the light emitting element 33a on the other surface so as to sandwich the disk 31b. .

The light receiving element 33b can receive light from the light emitting element 33a only when the slit 311b carved in the disk 31b rotating in synchronization with the rotation of the impeller 30 passes through the light emitting element 33a. Based on the timing, the blade tip position corresponding to the slit 311b is detected.

The control unit 40 includes a drive control unit 41 that controls driving of the impeller 30, a conveyance drive control unit 42 that controls driving of the conveyance path 10, a conveyance speed detection unit 43 that detects the conveyance speed of the conveyance path 10, and A conveyance distance acquisition unit 44 that acquires the distance of the conveyance path 10 and a conveyance that stores in advance the distance of the conveyance path 10, that is, the distance of the conveyance path that is conveyed from when the paper sheet length is acquired until it enters between the blades. It has a distance memory 45, a rotational speed memory 46 for storing the rotational speed of the impeller 30 in advance, and a bus 47 for performing data transmission / reception.

Here, the timing immediately before the banknote enters the central portion between the blades adjacent to the impeller 30 will be described. FIG. 4 is an explanatory view simply showing a state in which the leading edge of the banknote enters the central portion between adjacent blades.

As shown in FIG. 4, the banknote transported on the transport path 10 is immediately before entering the central portion between the blades adjacent to the impeller 30 provided at the end of the transport path 10, and the front end of the banknote is between the adjacent blades. When it is a place located in the center part 101, after that, the roller 11a can enter the predetermined center area | region between adjacent blade | wings by pushing a banknote in the direction between blade | wings.

However, when the banknote transported on the transport path 10 is just before entering the central portion between the blades adjacent to the impeller 30, the tip of the banknote is not located at the central portion 101 between the adjacent blades. When the roller 11a pushes out the bill in the direction between the blades, the tip of the bill may collide with the tip of the blade and cannot enter the central part between adjacent blades.

Or after the front-end | tip of a banknote approached the center part between adjacent blade | wings, the banknote which conveyed the conveyance path 10 may be unable to fully enter into the predetermined center area | region between adjacent blade | wings after that. .

In order to avoid this, the drive control unit 41 is configured so that the leading edge of the banknote is positioned at the central part between the next blades at the timing immediately before entering the central part between the blades adjacent to the impeller 30. It is necessary to control the rotation speed of the vehicle 30 so as to rotate at a high speed.

Therefore, the drive control unit 41 divides the conveyance distance acquired by the conveyance distance acquisition unit 44 by the conveyance speed detected by the conveyance speed detection unit 43, so that the leading edge of the bill enters the central part between adjacent blades. The timing just before is calculated.

The drive control unit 41 controls the driving of the stepping motor in units of one sheet so that the leading edge of the banknote is positioned at the center between adjacent blades at the calculated timing.

For example, if the leading edge of the bill has passed through the central portion between adjacent blades at the calculated timing, the drive control unit 41 impeller is positioned so as to be positioned at the central portion between the adjacent blades thereafter. The control is performed at a high rotational speed of 30.

Also, a state in which a bill has entered a predetermined central area between the blades adjacent to the impeller 30 will be described. FIG. 5 is an explanatory view simply showing a state in which the banknote has sufficiently entered a predetermined central region between adjacent blades.

As shown in FIG. 5, when the leading edge of a bill enters the central part between adjacent blades and sufficiently enters a predetermined central region between adjacent blades, the leading edge of the banknote is deep in the predetermined central region between the blades. The impeller 30 that reaches 201 and rotates is rotated while the banknotes are accommodated between the adjacent blades until the banknotes are stacked in the banknote stacking port 52.

At that time, as shown in FIG. 5, the rotating impeller 30 supports the banknotes at three points, that is, the back part 201 of the blades 31, the bent part 202 of the blades 31 a, and the tip 203 of the blades 31 a. Therefore, the banknotes can be collected with high accuracy and good condition.

Here, when a bill whose bill length is longer than the reference length is inserted into the bill stacker 1, until the leading edge of the bill enters the central portion between adjacent blades and sufficiently enters a predetermined central region between adjacent blades. When the rotational speed of the impeller 30 is low, the bank 11 is pushed out by the roller 11a in a state where the leading edge of the banknote has reached the back of the blade 201. At the moment when it is separated from the roller 11a, the banknote is separated from the blade back 201 and the impeller 30 cannot support the banknote at the above three points 201 to 203 during the banknote stacking. Accumulation cannot be performed in good condition such as jumping out from between the blades.

In order to avoid this, when a bill whose bill length is longer than the reference length is inserted into the bill stacker 1, the drive control unit 41 sets the rotational speed of the impeller 30 to be higher than the rotational speed corresponding to the reference length. It is necessary to control to rotate.

In addition, when a bill whose bill length is shorter than the reference length is inserted into the bill stacker 1, the leading edge of the bill enters the central portion between adjacent blades and sufficiently enters a predetermined central region between adjacent blades. When the rotational speed of the impeller 30 in the middle is high, the banknote does not reach the back of the blade 201. Therefore, the impeller 30 cannot support the banknote at the three points 201 to 203 during the banknote accumulation, and the banknote Accumulation cannot be performed in good condition such as jumping out from the space.

In order to avoid this, when a bill whose bill length is shorter than the reference length is inserted into the bill stacker 1, the drive control unit 41 sets the rotational speed of the impeller 30 to be lower than the rotational speed corresponding to the reference length. It is necessary to control to rotate.

Therefore, the drive control unit 41 drives the stepping motor in units of one sheet based on the banknote length acquired from the banknote length acquisition unit 20 so that the banknote can sufficiently enter a predetermined central region between adjacent blades. Is to control.

When the banknote length acquired from the banknote length acquisition unit 20 is longer than the reference length, the drive control unit 41 controls the driving of the stepping motor to rotate faster than the rotation speed corresponding to the reference length.

On the other hand, when the bill length is shorter than the reference length, the drive control unit 41 controls the driving of the stepping motor to rotate at a lower speed than the rotation speed corresponding to the reference length.

For example, the drive control unit 41 controls the rotational speed of the impeller 30 to be 25% with respect to the transport speed of the banknote transporting the transport path 10 when the banknote length is a reference length banknote.

Moreover, the drive control part 41 is controlled to make the rotational speed of the impeller 30 faster between 25% and 40% with respect to the conveyance speed of a banknote, when the banknote length is longer than a reference | standard length. is there.

And when the banknote length is shorter than the reference length, the drive control unit 41 controls the rotation speed of the impeller 30 to be slower between 25% and 20% with respect to the banknote conveyance speed. is there.

Normally, a stepping motor can be driven in proportion to the amount of pulse power sent. However, if the pulse power amount is changed significantly in order to make a sudden change in driving, the pulse power amount and the stepping motor In some cases, the stepping motor may not be driven in proportion to the amount of pulse power.

In order to avoid such a phenomenon, when the drive control unit 41 controls the rotational speed of the impeller 30 to be high or low, after the banknote reaches the back of the predetermined central region between adjacent blades. Returning to the normal rotation speed, the stepping motor is controlled so as not to change suddenly.

The conveyance drive control unit 42 can enter the banknote length acquisition unit 20 so that the leading edge of the banknote can enter without colliding with the leading edge of the blade and can sufficiently enter the predetermined central region between the adjacent blades. The rotation drive of the conveyance path 10 is controlled in units of one banknote based on the banknote length acquired from 1.

The conveyance speed detection part 43 detects the conveyance speed of the banknote conveyed on the conveyance path 10, when controlling the rotational drive of the impeller 30 and the conveyance path 10. FIG.

The conveyance distance acquisition unit 44, for example, stores the distance from the position of the timing sensor in the sensor mechanism 21 to the central portion between the blades adjacent to the impeller 30 provided at the end of the conveyance path 10 from the conveyance distance memory 45 that stores in advance. Configured to get.

The transport distance memory 45 stores in advance, for example, the distance from the position of the timing sensor in the sensor mechanism 21 to the central portion between the blades adjacent to the impeller 30 provided at the end of the transport path 10.

For example, when the drive control unit 41 controls the driving of the stepping motor based on the banknote length acquired from the banknote length acquisition unit 20, the rotational speed memory 46 is longer than the reference length, the reference length, and the reference length. The rotational speed at which the stepping motor is driven corresponding to each of the cases where the length is less than or equal to the length is stored in advance.

The paper sheet stacking apparatus described in the present application is the banknote stacking apparatus 1, the transport means is the transport path 10, the paper sheet length acquiring means is the banknote length acquiring unit 20, the rotary stacking means is the impeller 30, and the rotation driving means. The rotary drive unit 32 and the drive control means correspond to the drive control unit 41.

Further, the conveyance speed detection means described in the claims corresponds to the conveyance speed detection section 43, the conveyance distance acquisition means corresponds to the conveyance distance acquisition section 44, and the blade tip position detection means corresponds to the impeller mechanism 31 and the blade tip position detection section 33.

Further, the paper length management means described in the claims corresponds to the paper length management memory 23, the type identification means corresponds to the denomination identification unit 22, and the paper length measurement means corresponds to the sensor mechanism 21.

Next, the operation of the banknote stacking apparatus 1 according to the present embodiment will be described with reference to FIG. FIG. 6 is a flowchart showing the processing operation inside the banknote stacking apparatus related to the banknote stacking process of the banknote stacking apparatus.

In FIG. 6, the control unit 40 determines whether there is a banknote to be stacked at the banknote slot 51 (step S101). The control part 40 complete | finishes a processing operation, when there is no banknote which accumulate | stores in the banknote insertion slot 51 (step S101: No).

On the other hand, when there is a banknote to be stacked at the banknote insertion slot 51 (step S101: Yes), the roller 11a takes the banknote from the banknote slot 51 into the transport path 10 inside the banknote stacking apparatus (step S102). Then, the banknotes taken in units of one sheet are transported to the banknote length acquisition unit 20 provided on the transport path 10.

And the sensor mechanism 21 detects the banknote information which can identify a money type of the banknote taken in step S102 with a sensor etc. (step S103), and the money type identification part 22 detected by the sensor mechanism 21. Based on the banknote information that can identify the denomination, the denomination of the banknote is identified (step S104).

Subsequently, the banknote length acquisition unit 20 acquires the banknote length stored in the banknote length management memory 23 based on the denomination identified in step S104 (step S105).

The drive control unit 41 calculates and calculates the timing immediately before the leading edge of the banknote enters the central part between adjacent blades based on the transport speed at which the banknote transports the transport path 10 and the transport distance of the transport path 10. At the timing, the rotational speed of the impeller 30 (hereinafter referred to as “entry position control speed”) that allows the leading edge of the banknote to enter the central portion between adjacent blades is calculated (step S106).

And the drive control part 41 controls the drive of a stepping motor so that the rotational speed of the impeller 30 may become the approach position control speed calculated by step S106 (step S107).

Thereafter, the drive control unit 41 calculates the rotational speed of the impeller 30 according to the banknote length acquired in step S105 (step S108).

The control unit 40 determines whether or not the leading edge of the bill has entered the central portion between adjacent blades (step S109). When the leading edge of the banknote has not entered the central part between adjacent blades (step S109: No), the control unit 40 proceeds to step S109 until the leading edge of the banknote enters the central part between adjacent blades. Repeat the determination process.

On the other hand, the drive control part 41 controls the drive of a stepping motor so that it may become the rotational speed calculated by step S108, when the front-end | tip of a banknote approached into the center part between adjacent blade | wings (step S109: Yes) (step S109: Yes). Step S110).

Furthermore, the control unit 40 determines whether or not the leading edge of the banknote has reached the back of the predetermined central region between adjacent blades (step S111). When the leading edge of the banknote does not reach the back of the predetermined central area between the adjacent blades (step S111: No), the control unit 40 reaches the back of the predetermined central area between the adjacent blades. Until it is done, the determination process of step S111 is repeated.

On the other hand, the drive control part 41 controls the drive of a stepping motor so that it may become normal rotation speed, when the front-end | tip of a banknote reaches | attains the back of the predetermined center area | region between adjacent blade | wings (step S111: Yes). (Step S112).

And the control part 40 determines whether there exists a banknote which accumulate | stores in the banknote insertion slot 51 (step S113). When there is a banknote to be stacked at the banknote insertion slot 51 (step S113: Yes), the process proceeds to the processing operation of step S102, and the process for each banknote is repeated.

On the other hand, the control part 40 complete | finishes a processing operation, when there is no banknote which accumulate | stores in the banknote insertion slot 51 (step S113: No).

According to the present embodiment, the control unit 40 is positioned at the central part between the next blades immediately before the leading edge of the banknote enters the central part between the blades adjacent to the impeller 30 in units of one sheet. In addition, the rotational speed of the impeller 30 is controlled.

Furthermore, the bill length of each bill is acquired, and the rotational speed of the impeller 30 after entering the central portion between the blades adjacent to the impeller 30 is controlled based on the bill length.

Thereby, even when banknotes having different banknote lengths are mixed and thrown into the banknote stacking device, the front end of the banknote can enter without colliding with the front end of the blade, and the predetermined center region between adjacent blades can be entered. It is possible to enter sufficiently, and it is possible to accumulate the banknotes with high accuracy in a good state.

In addition, in the said Example, the banknote length acquisition part 20 detects the banknote information which can identify the money type of the taken-in banknote, identifies a money type based on the detected banknote information, and uses it for the identified money type. Based on this, the banknote length stored in the banknote length management memory 23 is acquired.

However, the light receiving element detects the time during which the light emitted from the light emitting element of the sensor is blocked by the banknote passing through the transport path 10, and acquires the banknote length based on the detected banknote passing time and the transport speed. You may do it.

In this case, there is no need to store the banknote length in advance in the banknote length management memory 23, and no processing for acquiring the banknote length stored in the banknote length management memory 23 is performed based on the denomination. 1 storage capacity and processing time can be greatly reduced.

Moreover, in the said Example, when the control part 40 controls the rotational speed of the impeller 30, in the case of a banknote whose banknote length is longer than a reference length, in the case of a reference length, and a case where it is shorter than a reference length, it rotates in three steps. The speed was changed.

However, the rotational speed may be controlled to vary in proportion to the banknote length of each banknote. In this case, the rotational speed can be controlled in more detail, and accordingly the state of the banknote is improved with higher accuracy. Accumulation can be performed.

Moreover, in the said Example, although the control part 40 was controlled to fluctuate the rotational speed of the impeller 30, based on the rotational speed of the impeller 30, the conveyance speed of the banknote conveyed on the conveyance path 10 is also combined. In this case, the banknotes can be stacked with higher accuracy and better state.

In the above-described embodiment, the rotation driving unit 32 and the conveyance driving unit 12 are described as using stepping motors. However, cheaper motors that can vary the rotational driving of the motors may be used. In this case, the cost of parts can be reduced.

Moreover, in the said Example, the control part 40 is set so that the front-end | tip of a banknote may be located in the center part between subsequent wing | blades at the timing just before approaching to the center part between the blade | wings adjacent to the impeller 30. FIG. The control is performed by increasing the rotational speed of the impeller 30.

However, the control may be performed at a low rotation speed of the impeller 30 so that the leading edge of the banknote is located at the center between the previous blades.

Moreover, in the said Example, although demonstrated taking the case of the banknote stacking apparatus 1 which identifies a banknote, it can apply also to other arbitrary paper sheets, such as a check other than a banknote, a bill, and a gift certificate. Needless to say.
