Abstract

The present invention makes it possible to restart an accumulation process with a very short interruption time after paper sheet bundles previously accumulated are transferred to an extraction area without causing increases in size and cost and, furthermore, without causing paper sheet jams in a bladed wheel. In addition, the present invention achieves both large-volume accumulations and small-volume accumulations with a single paper sheet processing device. An accumulation tray device 50 that individually accumulates paper sheets discharged from a bladed wheel 10 comprises: a first accumulation tray 51 that accumulates paper sheets when in the accumulation position P1 and that moves to a withdrawal position P2 when the accumulated paper sheet count reaches a prescribed count; and a second accumulation tray 71 that moves to an accumulation position P4 when the first accumulation tray is moved to the withdrawal position and accumulates paper sheets and that is rotated and moved to a withdrawal position P3 when the accumulated paper sheet bundles have been extracted. The accumulated paper sheet bundles can be individually extracted to the outside when the first accumulation tray is in the withdrawal position and the second withdrawal tray is in the accumulation position.

Description

Paper leaf processing device, stacking tray device, and paper leaf stacking method

The present invention relates to a paper sheet processing device such as a paper sheet counting device, an accumulation tray device, and an improvement of a paper sheet accumulation method.

The banknote counting device as a kind of paper sheet counting device separates the banknote bundles accumulated in the hopper section one by one, feeds them out, transports them to the identification section, and counts the banknotes that identify the denomination, authenticity, etc. At the same time, it is provided with a configuration for re-accumulating a predetermined number of sheets in an aligned state by transferring them into a stacker (accumulation storage) by an impeller. The banknote bundles re-accumulated in the stacker until a predetermined number (designated number) is reached are manually taken out and subjected to processing such as strapping.

However, in the conventional banknote counting device, the counting process is temporarily stopped when a predetermined number of banknotes are accumulated in the stacker, and the counting process is suspended until the accumulated banknote bundle is removed from the stacker. It was necessary to remove the bundle of accumulated banknotes in order to resume.
On the other hand, the worker must not only take out the banknote bundle from the stacker, but also perform various complicated and time-consuming work such as bundling the taken out banknote bundle with a strap or a rubber band and preparing a banknote bundle to be counted next. .. Since the banknote bundles are taken out in the meantime while performing such work, it is not always possible to immediately take out the banknote bundles from the stacker immediately after the counting and accumulation of a predetermined number of banknotes are completed, and the timing of taking out the banknote bundles is different. Become slow. For this reason, the standby state of the counting device may occur frequently or the waiting time may become long, and the efficiency of bill counting, strapping work, etc. has been significantly reduced. In particular, when counting a large number of banknotes, it has not been realized even though there is a strong demand for continuous processing without stopping the counting work as much as possible or with the minimum necessary interruption time. ..
In order to eliminate such a standby state and shorten the standby time, a plurality of stackers are installed side by side, and when the number of accumulated sheets in one stacker reaches a predetermined number, subsequent bills are accumulated in the other stacker by a switching means. A device for making the device has been proposed, but this has led to an increase in the size and cost of the device.

Patent Document 1 discloses a method and an apparatus for stacking sheet materials provided with a mechanism for dividing and stacking banknotes continuously supplied from a hopper in units of a predetermined number, for example, 100 sheets. In this device, banknotes that rotate and move while being inserted between the blades of the impeller are separated from the impeller by a stripper and dropped onto a stacking shelf for stacking, and when the number of stacks reaches a predetermined number. Retract the stripper to a position where it does not interfere with the banknotes on the impeller. After a predetermined number of banknotes have been accumulated on the accumulation shelf and before the accumulated banknote bundle is removed from the accumulation shelf, the auxiliary accumulation shelf is introduced between the impeller and the accumulation banknote, so that the subsequent banknotes can be placed on the auxiliary accumulation shelf. Accumulate continuously. According to this, it is said that the interruption time can be shortened by separating the banknote bundle accumulated in a predetermined number of banknotes and the subsequent banknote bundle.

However, Patent Document 1 has the following problems.
First, in recent years, a banknote counting device is required to increase the number of processed banknotes, for example, high-speed processing of about 15 sheets / second. However, in Patent Document 1, a predetermined number of banknotes, for example, the 100th banknote is accumulated on an accumulation shelf. The stripper must be retracted in an extremely short time until the subsequent 101st bill, which is continuously supplied, arrives after the completion of the above, and there is a problem in its responsiveness. It is doubtful that a mechanism for causing the stripper to operate at such a high speed can be realized. That is, the configuration of Patent Document 1 is not suitable for high-speed processing of 15 sheets / sec.

In addition, while the stripper is retracted, the banknotes are sequentially pushed into the individual banknote storage spaces between the adjacent blades and stored in a stacked state, so that the banknotes are stored in the individual banknote storage spaces. There is a high risk of collisions (jams) between banknotes. That is, it is impossible to realize high-speed processing of banknotes while preventing the occurrence of jam by accommodating only one banknote in the banknote storage space.
Further, in recent banknote counting devices, a mechanism is required to sequentially read the serial numbers of banknotes transported from the hopper one by one, record and utilize them in the order in which they are transported, but there are a plurality of banknotes in the banknote storage space between the blades. If the banknotes are stacked and held, they cannot be collected in the order in which they were transported when they were separated from the blades and collected. That is, in Patent Document 1, after all 100 banknotes, which is the unit accumulation number, are held by each banknote storage space of the impeller, the stripper is operated to separate the banknotes in each banknote storage space onto the collection shelf. There is. However, since the number of bill storage spaces formed between the blades of the impeller is less than 100, which is the unit accumulation number, it is necessary to stack and hold a plurality of bills in one bill storage space. Assuming that the number of bill storage spaces is 20, the first bill is stored in the first bill storage space that has moved to the bill supply position on the outer periphery of the impeller, and the second bill is stored in the next bill storage space. When the banknotes of No. 1 are sequentially stored, the 21st banknote is stored in an overlapping manner with the first banknote in the first storage space. When the storage of the 100th banknote is completed, five banknotes are finally stored in all the banknote storage spaces, and at this stage, the stripper is operated to collect the banknote bundle in each banknote storage space. When the banknotes are sequentially separated and collected on the accumulation shelf, the order of the banknotes is different from the order of the banknotes sent from the hopper. That is, with respect to the first bill storage space, the 21st bill, the 41st bill, the 61st bill, and the 81st bill are sequentially stacked on the first bill. Therefore, the order of the accumulated banknotes on the accumulated shelves is also the same.
As described above, in the apparatus configuration of Patent Document 1, it is not possible to sequentially read the serial numbers of banknotes transported from the hopper one by one, and record and utilize them in the order in which they were transported.

Next, in Patent Document 2, the accumulated paper leaves are collected in the process of naturally dropping the paper leaves (banknotes) held by the impeller onto an ascending / descending mounting table having a horizontal mounting surface. Paper leaf processing in which a partition member is projected laterally above the previously accumulated paper leaf bundle when changing to that of the next account so that subsequent paper leaves are accumulated on the partition member. The device is disclosed. However, since the paper sheets on the mounting table are not pressurized, if they contain a large number of non-flat deformed banknotes, they may swell in the thickness direction and the total thickness may exceed the thickness expected at the time of design. In this case, the partition member protruding from the lateral direction collides with the side surface of the thickened paper banknote bundle to generate jam. In addition, the naturally falling bills are not stable in the falling posture, and land on the mounting table in a state of being displaced in the long side direction, the short side direction, or the diagonal direction. For this reason, the positions in the surface direction between the banknotes are variously dispersed, resulting in an unaligned state, and the work of rearranging the banknote bundles when the post-processing such as strapping is manually performed becomes complicated.
Patent Document 3 has a similar problem.

Further, in recent banknote counting devices, users are required to increase the accumulated capacity, for example, to increase the accumulated capacity from 100 sheets to 500 sheets, and the accumulation space tends to be increased. However, for a user who desires processing in units of a small number of sheets of about 100 sheets, most of the space for 500 sheets is wasted, which causes the device to become larger than necessary.

Patent No. 4390145 Japanese Unexamined Patent Publication No. 62-16981 JP 2001-76209

The present invention has been made in view of the above, and when a large amount of paper sheets are continuously counted and accumulated, the size of the device is increased by adding stackers, the cost is increased, and the paper leaf storage space of the impeller A paper leaf processing device that can restart the stacking process with an extremely short interruption time without causing jamming between the paper sheets inside and without removing the bundle of paper sheets that has been accumulated in advance from the stacker. , A collection tray, and a method for collecting paper sheets.
Further, it is intended that the stacking order of the paper sheets discharged from the impeller and collected is the same as that when the paper sheets are fed from the hopper section.
Another object of the present invention is to provide a technique capable of realizing both large-capacity accumulation and small-capacity accumulation by two divisions by one paper sheet processing device.

In order to achieve the above object, the paper leaf processing apparatus of the present invention holds a plurality of blades radially protruding around a rotation axis and a single sheet of paper formed between the adjacent blades and received.

A first accumulation tray that accumulates leaves and moves to a retracted position retracted rearward from the leaf accumulation position when the number of accumulated paper leaves reaches a predetermined number, and the first accumulation tray is the paper leaf accumulation position. While it is in the retracted position retracted from the paper leaf accumulation position, when the first accumulation tray moves to the retracted position or in the process of moving, it moves to the paper leaf accumulation position and is discharged. When the first stacking tray is in the retracted position, the first stacking tray is provided with a second stacking tray that accumulates paper sheets and is rotationally moved to the retracted position when a predetermined number of stacked paper leaf bundles are taken out. And, when the second stacking tray is in the paper leaf stacking position, it is possible to take out the stack of paper leaf bundles to the outside.

According to the present invention, when a large number of paper sheets are continuously counted and then accumulated, the bundle of paper sheets that has been accumulated in advance is not removed from the stacker and is accumulated through an extremely short interruption time. Processing can be resumed. In addition, one paper sheet processing device can realize both large-capacity accumulation and small-capacity accumulation.

FIG. 6 is an explanatory diagram showing an arrangement example of various sensors arranged in the stacker unit (impeller and integrated tray device).

In addition, although the banknote as an example of the paper leaf will be described in this embodiment and all the following embodiments, the paper leaf is not only a banknote but also a sheet-like material such as securities, gold tickets, tickets, etc. regardless of the material. Is widely included.

The banknote counting device 1 has a plurality of blades 15 projecting radially (curved) about a rotation axis 11 and a paper sheet holding space 17 formed between adjacent blades and holding a received sheet. The impeller 10 is provided with, and when the banknotes are rotated in the banknote storage direction indicated by the arrow in FIG. 1, one sheet of paper B held in each leaf holding space is sequentially discharged into a predetermined banknote collection area. Banknote supply means (hopper, banknote supply and transport means) that supplies banknotes one by one to the banknote transport path (banknote supply and transport means) 100 that supplies banknotes one by one from the outer diameter direction into each bill holding space 17 of the impeller. ) 30, a stacking tray device 50 that is arranged in the banknote collection area SA and holds the paper sheets discharged from each paper leaf holding space 17 one by one in a stacked state, drive

mechanisms

60, 80, a drive mechanism, etc. The control means 200 for controlling various control targets of the above is provided.

The stacking tray device 50 collects the bills discharged when it is at the bill stacking position (banknote receiving position (posture)) P1 facing the impeller 10, and also collects the bills when the number of bills accumulated reaches a predetermined number. When the first accumulation tray 51 retracted from the accumulation position P1 to the retracted position P2 and the first accumulation tray is at the bill accumulation position (accumulation position) P1, the accumulation position P1 or the first accumulation tray moves forward and backward. While it is in the retracted position P3 retracted from the route, when the first accumulation tray retracts to the retracted position P2 (or in the process of retracting), it is rotated to the bill accumulation position P4 (banknote receiving position) and released. In addition to accumulating the incoming banknotes, a second accumulating tray 71 that is rotationally moved to the retracted position P3 when a predetermined number of accumulated paper leaf bundles are taken out is provided. Then, when the first accumulation tray 51 is in the evacuation position P2 and when the second accumulation tray 71 is in the bill accumulation position (accumulation position) P4, the accumulated paper leaf bundle can be taken out to the outside, respectively.

Hereinafter, the specific configuration of the bill counting device 1 will be described in more detail.
The bill supply means 30 separates the payout roller 31 for feeding out the bills on the lowermost surface by rotating in contact with the lower surface of a large number of bill bundles BBa before counting, which are laminated on a laminated plate (not shown). It also has a separation roller pair 32 for preventing double feeding, which is sent out to the bill transport path (banknote supply and transport means) 100. The separation roller pair 32 is composed of a lower feed roller 32a that is rotationally driven in the paper feed direction and a brake roller 32b that is arranged above the feed roller and is made of a high friction material that nips with the feed roller.
A banknote transport path (banknote supply and transport means) 100 including a belt, a transport means such as a roller, and a motor (not shown) is provided between the bill supply means 30 and the impeller 10 and is provided on the bill transport path 100. An identification unit 110 for determining the authenticity and denomination of banknotes is provided. The first gate 120 and the second gate 122 are sequentially arranged at positions in front of the impeller 10 of the banknote transport path. Each gate is rotatably configured around a rotation shaft, is rotated by a solenoid (drive mechanism) (not shown), and is controlled and operated by the control means 200 to set the destination of banknotes to the regular transport path 100a. It selectively switches to the branch transfer path 100b and the reject transfer path 100c.

As will be described later, the first gate 120 is a means that operates when another stacker unit SU is connected to switch the transfer destination to the branch transfer path 100b for transporting banknotes to the other stacker unit. The second gate 122 is a means for switching the transport destination to either a regular transport path 100a toward the impeller 10 or a reject transport path 100c for transporting banknotes to the reject portion 130 provided below.
The control means (CPU, ROM, RAM) 200 controls each control target based on operation signals from operation switches, detection signals from various sensors, and the like.
The impeller 10 constitutes an impeller drive unit UN1 together with its drive mechanism 20.
The stacking tray device 50 constitutes the stacking tray drive units UN2 and UN3 together with the

drive mechanisms

60 and 80.

Next, the impeller drive unit UN1 will be described with reference to FIGS. 2 and 5.
In this example, two impellers 10 having the same shape are fixed to the rotating shaft 11 at a predetermined axial distance, and a bill holding space is formed between the blades 15 of the two impellers. According to 17, the short side is rotated while holding two long sides of the bill being transported in a posture parallel to the transport direction. Each impeller 10 includes a disk-shaped base 12 integrated with a rotating shaft 11, a plurality of blades 15 made of an elastic material that protrudes radially and spirally (curved) from the outer periphery of the base, and in the circumferential direction. It is provided with a bill holding space 17 formed between adjacent blades and holding a received bill so that it can be freely put in and taken out.
The impeller drive mechanism 20 includes an impeller motor 21, an intermediate gear 22 that meshes with the output gear 21a of the impeller motor, and a small gear 22a that is integrated with the intermediate gear 22 with the shaft core fixed to the rotating shaft 11. A driven gear 23 that meshes with the driven gear 23 is roughly provided. By driving the impeller motor 21, the impeller 10 rotates in the bill storage direction indicated by the arrow.

As shown in FIG. 5, when the stacker unit SC in which the first and second integrated tray drive units UN2 and UN3 are assembled to the impeller drive unit UN1, the stacker unit SC is manufactured so as to cover the rotating shaft 11. The space and the space outside each impeller are covered by the impeller guide 26. Since the upper surface (stopper for removing bills) 26a of the impeller guide is in a positional relationship that interferes with the long side on the inner diameter side of the bill B that is held by the two impellers and rotates, the bill B is in contact with the upper surface 26a. After that, the bill is pushed up by the upper surface 26a. This pushing force acts in the direction of separating the bills from the bill holding vacant spaces 17, and the bills separated from the bill holding vacant spaces are sequentially discharged to the bill collecting area located in the outer diameter direction of the impeller. Therefore, two or more subsequent banknotes are not stacked and held in one banknote holding space. Further, since the bills in the bill holding vacant space 17 are surely separated by the upper surface 26a, the bills are not already held when the impeller rotates and the bill holding vacant space reaches the bill supply position 100A. ..

Next, the first integrated tray drive unit UN2 will be described with reference to FIGS. 3 and 5.
The first integrated tray 51 and its drive mechanism 60 constitute the first integrated tray drive unit UN2.
The first accumulation tray 51 has an L-shaped front surface, and includes a bottom plate 52 and a back plate 54 that is bent by approximately 90 degrees from the rear end edge of the bottom plate 52 and stands up. The bottom plate 52 is a means for supporting the lower long side of the bill discharged from the impeller into the bill collecting area, and the back plate 54 is a means for supporting the back surface of the bill.
The first stacking tray 51 as the first stacker has the bill bundle stacking position P1 shown in FIGS. 3 (a-1), (b-1), and (c-1) by the drive mechanism 60, and FIG. 3 (a-2) ( b-2) It advances and retreats linearly with the retracted position P2 shown in (c-2).

In this example, the bottom plate 52 has a configuration in which three elongated plates are arranged in parallel at intervals, but this is an example, and if the bottom of a bundle of banknotes stacked in a horizontally long state can be stably supported. Good. The upper surface of each elongated plate may be formed on the same plane. Similarly, the back plate 54 may have a configuration that can stably support the back surface of the banknote bundle supported on the bottom plate in an upright state. Since the long side of the banknote bundle is placed on the flat upper surface of the bottom plate 52, even if the banknotes are displaced, they are only in the longitudinal direction and there is no deviation in the width direction. Therefore, it is possible to facilitate the manual alignment work after taking out the banknote bundle.
The bill collection area SA is an area where bills separated from the bill holding vacant spaces 17 of the impeller are discharged, and the first collection tray device 51 and the collection position P1 closest to the impeller are in the bill collection area. , Both the retracted positions P2 located behind the accumulation position are included. Further, the position of the evacuation position P2 is not uniquely determined to the position shown in the drawing, and covers a wide range in the inner part of the bill collection area.

When the first accumulation tray 51 is at the bill accumulation position P1 shown in FIGS. 7 (a) to 7 (d), the bottom plate 52 and the back plate 54 face the impeller and are discharged one by one from the impeller. The bills are sequentially received on the bottom plate 52 and the back plate 54 and held in an upright state. As will be described later, stable accumulation can be realized by setting the bill accumulation position P1 so as to maintain an appropriate distance from the impeller.
In the two-segment accumulation mode, the first accumulation tray 51 is moved back and forth between the bill accumulation position P1 and the retracted position P2 by its drive mechanism 60. Further, in the large-capacity accumulation mode described later, the first accumulation tray is controlled so as to retreat from the initial banknote accumulation position P1 by a predetermined distance as the number of accumulated banknotes increases. In this case, it moves further backward beyond the evacuation position P2.
When the first collection tray 51 is at the bill collection position P1, it is closest to the impeller and maintains an appropriate interval, so that the bills are efficiently collected in the correct standing posture without falling or shifting on the bottom plate 52. It becomes possible.

On the other hand, in the large-capacity accumulation mode, the first accumulation tray is determined at an appropriate timing so that the distance between the front surface of the banknote bundle BB1 already accumulated on the first accumulation tray 51 and the impeller becomes an appropriate value. Control to move backward by distance. By this control, the distance between the front surface of the accumulated banknote bundle BB1 and the impeller is kept constant, and it is possible to efficiently collect the accumulated banknotes in the correct standing posture.
As shown in FIG. 3, the drive mechanism 60 of the first integrated tray 51 includes a first integrated tray motor 61, an output pulley 61a of the integrated tray motor, a driven pulley 62a arranged below the motor 61, and both pulleys 61a. , The endless belt 63 wound between 62a, the driven gear 62 coaxially integrated with the driven pulley 62a, the rack gear 64 arranged at the bottom of the bottom plate 52 and meshing with the driven gear 62, and the first It includes a guide rail 65 that guides the stacking tray 51 in the front-rear direction so as to be able to move forward and backward.
By driving the first integrated tray motor 61 composed of a stepping motor in the forward and reverse directions, the driving force is transmitted to the first integrated tray 51 via the belt 63, the driven gear 62, and the rack gear 64, and the first integrated tray 51 is in the integrated position. It advances and retreats linearly between P1 and the retracted position P2. By using a stepping motor, it becomes easy to finely adjust the position of the first integrated tray in the front-rear direction.

Further, as shown in FIG. 3 and the like,

photo interrupters

66a and 66b fixed to the main body of the apparatus are arranged in the movement path of the detected portion 55 provided on the side portion of the first integrated tray 51, and the photo interrupters 66a are arranged. Detects the home position (P1) of the first stack tray. The photo interrupter 66b detects the end position (P2) of the first stack tray. That is, the first accumulation tray 51 is in the home position when it is in the first accumulation position P1, and is in the end position when it is in the retracted position P2.

Next, the second integrated tray drive unit UN3 will be described with reference to FIGS. 4 and 5.
The second integrated tray 71 and its drive mechanism 80 constitute the second integrated tray drive unit UN3.
The second accumulation tray 71 has a retracted position P3 retracted above the bill accumulation area as shown in FIG. 7 and an accumulation position P4 lowered into the accumulation area as shown in FIG. 8 and the like by its drive mechanism 80. It is configured to rotate between and.
In the second integrated tray 71 according to this example, elongated thin plates having different lengths are alternately arranged and integrated so that the front surfaces of the thin plates form the same plane. The base end portion of the second accumulation tray 71 is fixed to the rotation shaft 73 and is rotationally driven by the drive mechanism 80. Since the second accumulation tray 71 is pivotally supported by the rotating shaft 73 provided on the casing 85, its position does not change even if the first accumulation tray moves forward and backward.

As shown in FIG. 4, the drive mechanism 80 of the second integrated tray 71 includes a second integrated tray motor 81, an intermediate gear 82 that meshes with the output gear 81a of the motor 81, and a small gear 82a integrated with the intermediate gear 82. It has a driven gear 83 that meshes with the driven gear 83, and a rotating shaft 73 is integrated with the shaft core of the driven gear 83. The two

photo interrupters

85a and 85b are respectively arranged in the rotational movement path of the detected member 75 projecting from the end of the rotational shaft 73. As a result, the photo interrupter 85a detects the home position (retracted position P3) of the second accumulation tray, and the photo interrupter 85b detects the end position (accumulation position P4) of the second accumulation tray.
The impeller drive unit UN1, the first integrated tray drive unit UN2, the second integrated tray drive unit UN3, and the casing 85 that supports them constitute the stacker unit SU.

FIG. 6 shows various sensors for detecting banknotes mounted on the stacker unit SU. The bill counting sensor CS is a photo interrupter that counts bills passing through the regular transport path 100a, and counts the number of bills supplied to the impeller from the bill supply position 100A to store the first stack tray 51 and the second stack. This is a means for counting the number of banknotes that are discharged and stacked on the tray 71.
The first bill presence / absence detection sensor S1 (light emitting element S1E, light receiving element S1R) is a photo interrupter that detects the presence / absence of bills on the first stacking tray 51 and the second stacking tray 71 located in the bill stacking area SA. The second bill presence / absence detection sensor S2 (light emitting element S2E, light receiving element S2R) is a photo interrupter that detects the presence / absence of bills behind the bill accumulation area (behind the back plate 54 at the first accumulation position).

[1-2: Accumulation operation in 2-segment integration mode]
Next, the bill counting and the stacking operation (stacking operation, stacking method) by the bill counting device will be described based on the flowcharts of FIGS. 7, 8, 9, and 10. Note that FIGS. 6 and 7 show only the stacker unit SU in which the bill supply means 30, the bill transport path 100, the identification unit 110, and the like are omitted.
As described below, the bill counting device 1 alternately moves the two stacking

trays

51 and 71 to the stacking position to collect a predetermined number of bills discharged from the impeller on each stacking tray2. It is possible to realize a compartmentalized integration mode and a large-capacity integration mode using only the first integration tray described later.

7 (a) to 7 (e) are diagrams for explaining the integration operation by the first accumulation tray in the two-segment accumulation mode, and FIGS. 8 (f) to 8 (k) are diagrams for explaining the integration operation by the second accumulation tray. 9 (l) to 9 (n) are diagrams for explaining the retracting operation of the second accumulation tray. FIG. 10 is a flowchart showing the counting by the bill counting device and the collecting operation by each stacking tray.
The following processing is performed on the premise of starting counting the passing bills in step S1 of FIG. That is, after the power of the bill counting device is turned on and the start switch is turned on, the control means 200 confirms that the bill bundle BBa is set on the bill feeding means 30. If it is set, the banknote supply means 30 and the motor for driving the banknote transport path 100 (banknote supply and transport means) are driven to start the counting process, thereby starting from the bottom of the banknote bundle BBa before counting. The banknotes are taken out one by one and sent to the banknote transport path 100. At this point, the impeller motor 21 may be driven.

When the banknotes transported by the banknote transfer path 100 pass through the identification unit 110, the authenticity and the denomination are determined. If the bill is not genuine or is not a predetermined denomination to be counted, the second gate 122 is operated to transport the bill to the reject unit 130 via the reject transport path 100c. When the bill is genuine and has a predetermined denomination, the impeller motor 21 is driven.
FIG. 7A shows that the first bill B1 sent from the bill supply means 30 (not shown) to the bill transport path 100 and sent to the regular transport path 100a via the first gate 120 and the second gate 122 is a bill. It shows the state immediately before reaching the count sensor CS. At this time, the control means 200 starts driving the impeller motor 21 and rotates the impeller 10 in the bill storage direction indicated by the arrow in FIG. 7B, so that the impeller 10 starts from the bill supply position 100A in the right direction. The banknotes B1, B2, B3, ... Sent to the outer periphery of the banknote are sequentially inserted into the banknote holding vacant spaces 17. At this time, the number of banknotes passed by the banknote count sensor CS is counted.
The long side on the inner diameter side (long side on the tip side in the insertion direction) of the first bill B1 inserted and held in one bill holding space 17 is the upper surface (stopper) of the impeller guide 26 as the impeller rotates. When it comes into contact with 26a, the banknote B1 cannot follow the rotation of the impeller any more, and moves toward the banknote accumulation area while being separated from the banknote holding space 17. At this point, since the first collection tray 51 is located in the bill collection area SA, the discharged bill B1 is held in contact with the bottom plate 52 and the back plate 54 constituting the first collection tray. Subsequent banknotes B2, B3, ... Are also sequentially laminated on the front surface of the banknote B1 (FIG. 7 (c)).

FIG. 7D shows a state at the time when a predetermined number of banknotes, 100 banknotes BB1 in this example, have been accumulated in the first accumulation tray 51, and the last 100th banknote passes through the banknote count sensor CS. Then, the impeller 10 is stopped after being accumulated in the first accumulation tray 51 through the banknote holding space 17 of the impeller, and the banknote supply by the banknote supply means 30 and the transfer by the banknote transport path 100 are also stopped (FIG. 10). , Step S1 YES, Step S2). At this point, the subsequent 101st banknote may come to the front of the banknote supply position 100A and stop, and the 102nd and subsequent banknotes already sent by the banknote supply means 30 may also be stopped. It may be stopped in the bill transport path 100.
When the stacker unit SU is single as in this example, the banknotes cannot be transported to other stacker units, so that all the banknotes in the single stacker unit SU are stopped. However, when a plurality of stacker units are connected as described later, subsequent bills can be continuously accumulated in other stacker units, so that it is not necessary to stop all the bill transport paths.

Next, in FIG. 7 (e), the first accumulation tray 51 at the accumulation position P1 (home position) is moved to the rear part (inner inner part) of the bill accumulation area SA by driving the drive mechanism 60 for the first accumulation tray. It shows a state of retracting to a certain retracted position P2 (end position) P2 (step S3). The control means 200 determines that 100 banknote bundles BB1 have been accumulated in the first accumulation tray 51 by the count signal from the banknote count sensor CS, and another banknote is placed in the retracted position P2 by the second banknote presence / absence detection sensor S2. After confirming that the first integrated tray 51 does not exist, the first integrated tray 51 is moved to the retracted position P2 by the drive mechanism 60 of the first integrated tray 51. The banknote bundle on the first accumulation tray at the evacuation position P2 can be taken out. Further, as will be described later, in this example, the banknote bundle on the first accumulation tray at the accumulation position P1 can also be taken out to the outside of the casing.

Further, in this example, the evacuation position P2 is set as the innermost part of the bill collection area, but the position on the front side of the innermost part may be set as the evacuation position.

FIG. 8 (f) shows a state immediately after the second integrated tray 71 is rotated by 90 degrees from the retracted position P3 (home position) shown in FIG. 7 and lowered by driving the motor 81 for the second integrated tray. .. In this state, the second accumulation tray 71, which had been in the evacuation position P3 until then, has moved to the accumulation position P4 (banknote accumulation area SA) as the end position (step S4). At this point, since the first accumulation tray 51 has already moved to the evacuation position P2, the second accumulation tray 71 is directly facing the impeller 10 and is in a positional relationship in which the discharged bills can be sequentially received. is there.
In the illustrated configuration example, when the second accumulation tray 71 moves to the accumulation position P4, it is separated from the front surface of the banknote bundle BB1 on the first accumulation tray 51, but the first accumulation tray at this point is separated. By setting the position in the front-rear direction of the above position to be a predetermined distance ahead of the position shown in the drawing, the second accumulation tray that has moved to the accumulation position P4 controls to pressurize the banknote bundle BB1 on the first accumulation tray. You can also do it.
That is, since the position of the first stacking tray in the front-rear direction can be arbitrarily adjusted, such control is possible.
When the second stacking tray is in the paper leaf stacking position in this way, the stack of paper strips piled up in the first stacking tray may be configured and controlled to be pressurized.

When the stack of paper bundles previously stacked on the first stack tray is not pressurized, the stack of paper bundles contains a large number of paper strips having an uneven deformation habit. It may bulge in the thickness direction and its total thickness may exceed the thickness expected at the time of design. As described in Patent Document 2 in the background technique, since the paper leaf bundle on the mounting table previously accumulated is not pressurized, the side surface of the paper leaf bundle in which the partition member protruding from the lateral direction is thickened. Collides with and causes jam.
In the present invention, by adjusting the position of the first stacking tray in the front-rear direction, it is possible to compress the bundle of paper sheets accumulated in the first stacking tray by rotating the second stacking tray to the paper leaf stacking position. Even if the bundle of paper swells in the thickness direction beyond the expectation at the time of design, the bundle of paper is compressed and crushed by the second accumulation tray, so that the bundle of paper can be stably accumulated.
The second accumulation tray descends by rotating 90 degrees from the retracted position P3 (home position) retracted upward from the bill accumulation area SA, and comes into contact with or faces the front surface of the banknote bundle BB1 on the first accumulation tray. It is a structure to do. Therefore, unlike the partition member of Patent Document 2, the second stacking tray does not collide with the side surface of the paper leaf bundle in the process of lowering. Therefore, the merit of pressurizing the banknote bundle on the first stacking tray by the second stacking tray is that if the banknote bundle is not pressurized, the alignment state of the banknote bundle on the first stacking tray deteriorates and the alignment workability after taking out the banknote bundle is improved. It is possible to prevent the problem of deterioration.

In FIG. 8 (g), after the first banknote presence / absence detection sensor S1 confirms that no banknotes are present in the front portion of the banknote accumulation area SA (step S5 YES), the banknotes are fed by the banknote supply means 30 and the banknote transport path. The banknote transport by 100 is restarted, and when the impeller count sensor CS detects the entry of the 101st banknote B101, the impeller rotation is restarted (step S7).
In this way, the control means 200 is operated by the paper leaf supply / transport means 30 and 100 and the impeller when a predetermined number of paper sheets are piled up on the first stacking tray 51 at the stacking position P1. Paper leaf discharge operation is stopped, the first stacking tray is retracted to the retracted position P2 in the inner part of the bill accumulation area SA, and the second stacking tray 71 is lowered to the stacking position P4 to supply the paper leaf. The transport operation and the paper leaf discharge operation are restarted.
That is, in this configuration example, when the accumulation of 100 banknotes in the first accumulation tray 51 is completed, the banknote supply means 30 does not continue feeding and transporting, but after the accumulation is completed, the first accumulation tray 51 The delivery and transportation of new banknotes are not resumed until the banknotes are retracted from the accumulation position P1. However, since this interruption time stays within 1 second, the overall processing speed is not significantly delayed even when high-speed counting processing of about 15 sheets / second is required.

If it is detected by the first bill presence / absence detection sensor S1 in FIG. 8 (g) that bills remain in the bill accumulation area (accumulation position P1), an error is taken. That is, if the first bill presence / absence detection sensor S1 detects that there is a bill in the bill accumulation area SA in step S5 of FIG. 10, an error occurs (step S6).
FIG. 8H shows a state in which the import of banknotes by the impeller is resumed, and one banknote B101, B102, B103, ... Is sequentially held in each banknote holding space 17 (step S7). ).
In FIG. 8 (i), similarly to FIG. 7 (c), the 101st banknote B101 held in the banknote holding space 17 and the subsequent banknotes B102, B103, ... As the impeller rotates. By coming into contact with the upper surface (stopper) 26a of the impeller guide 26, the banknotes are separated from the banknote holding vacant space and moved toward the banknote collection area, and are sequentially stacked on the second collection tray 71. In this example, the bottom plate 52 of the first accumulation tray is configured to have a long front-rear direction so that the back plate 54 extends to the lower part of the bill accumulation area SA even if the back plate 54 retracts to the evacuation position P2. Therefore, the 101st and subsequent banknotes can be received on the bottom plate 52. It should be noted that the support structure of the succeeding banknotes by making the bottom plate 52 long is not essential, and the banknotes may be directly accumulated on the lower surface of the banknote accumulation area (the bottom surface of the casing 85).

The banknote bundle BB2 accumulated in the second accumulation tray 71 at the accumulation position P4 can be taken out of the casing at any time, that is, after the stage where the accumulation in FIG. 8 (j) is completed.
In FIG. 8 (j), the impeller stops after the 200th banknote B200 passes through the banknote count sensor CS and is accumulated in the second accumulation tray 71 (step S8 YES, step S9). The banknote bundle BB2 shows a banknote bundle composed of 100 sheets from the 101st sheet B101 to the 200th sheet B200.

In step S10, the presence / absence of the first bill is determined by the first and second bill presence / absence detection sensors S1 and S2 on the front side and the rear side of the collection area SA with the second collection tray 71 as a boundary. If the detection sensor S1 detects the presence of banknotes on the front side (accumulation position P4), but the second banknote presence / absence detection sensor S2 does not detect the banknotes behind the accumulation area, the accumulation position is in step S11. Wait for the banknotes to be taken out from the second accumulation tray 71 on P4. Further, although the first bill presence / absence detection sensor S1 does not detect the presence of bills on the front side of the accumulation area (accumulation position P4), the second bill presence / absence detection sensor S2 is on the rear side of the accumulation area (first accumulation tray side). When the banknotes are detected, the process proceeds to step S12 and step S7 in order to collect the banknotes on the second accumulation tray 71 at the accumulation position P4.
If none of the bill presence detection sensors in step S10 detects the presence of bills, the second stack tray 71 is moved to the home position, the retracted position P3, by the second stack tray motor 81 in step S13.
Subsequently, in step S14, the first stacking tray 51, which had been in the retracted position P2 until then, is advanced in the stacking area to move to the stacking position P1, and in step S15, the impeller motor 21 is restarted.

FIG. 8K shows a state in which the accumulated banknote bundle BB1 at the evacuation position P2 and the accumulated banknote bundle BB2 at the accumulation position P2 are taken out from an outlet (not shown) provided in the casing 85. As a result, the banknote collection area SA becomes empty as a whole, and the 201st and subsequent banknotes can be collected in the first collection tray at the collection position P1. This corresponds to the case where none of the bill presence / absence detection sensors S1 and S2 detects the presence of bills in step S10.
FIG. 9 (l) shows the state immediately before the second stacking tray 71 retracts from the stacking position P4 to the retracting position P3, and FIGS. 9 (n) and 9 (m) show the first stacking tray after retracting the second stacking tray. It shows a state in which 51 is returned to the accumulation position P1.

After that, continuous processing can be continued by repeating the accumulation procedure described with reference to FIGS. 7 and 8. That is, when it is determined that the 200th banknote has been accumulated in the second accumulation tray 71, the transfer by the banknote supply means 30 and the banknote transport path 100 is interrupted, and both accumulated banknotes BB1 are displayed on a display unit (not shown). The operator is encouraged to take out the BB2 by indicating that the BB2 should be taken out from the evacuation position P2 and the accumulation position P4, respectively.
After that, each of the sensors S1 and S2 detects that no banknotes are present in the entire banknote accumulation area SA, that is, in any of the retracted position P2 of the first accumulation tray and the accumulation position P4 of the second accumulation tray, so that the second is The stacking tray 71 is moved to the retracted position P3 (step S13), and the first stacking tray is moved to the stacking position P1 (step S14). By restarting the feeding and transporting by the bill supplying means 30 and the bill transport path 100 at this timing, the accumulation of the 201st and subsequent bills can be started (step S15).
The time required from the stop of the impeller motor in step S2 to the resumption of rotation of the impeller motor in step S7 is less than 1 second. Further, the time required from the stop of the impeller motor in step S9 to the resumption of rotation of the impeller motor in step S15 is less than 1 second.

As described above, the banknote collection method (banknote processing method) according to the present embodiment includes a banknote supply operation by the banknote supply / transport means when a predetermined number of banknotes are collected in the first collection tray 51 at the collection position P1. The bill ejection operation by the impeller is temporarily stopped, and the first stacking tray is retracted from the stacking position P1 to the inner part of the bill stacking area SA. Subsequently, the second accumulation tray 71 at the evacuation position P3 is projected to the accumulation position P4 in the bill accumulation area, and then the bill supply operation and the bill discharge operation are restarted.
In other words, the banknote collection method (banknote processing method) according to the present embodiment is a banknote supply operation by the banknote supply / transport means and an impeller when a predetermined number of banknotes have been collected in the first collection tray at the banknote collection position. The step of stopping the bill ejection operation by the banknotes, the step of moving the first stacking tray to the retracted position P2, the step of moving the second stacking tray to the bill stacking position P4, and the step of moving the second stacking tray to the bill stacking position P4. At that time, the banknote supply operation and the step of restarting the banknote release operation are provided.

According to the banknote collection method (banknote processing method) by the banknote counting device 1 and the banknote processing device 1 of the present invention having the above configuration, only one banknote is held in one holding space 17 of the impeller. Since it does not hold a plurality of banknotes, banknotes do not collide with each other and cause jam in one holding space. In addition, since the bills held one by one in one holding vacant space are sequentially discharged to the bill collecting area before moving around to the bill supply position 100A for supplying the bills in the holding vacant space, each collecting unit. The stacking order of the banknotes collected in 51 and 61 always matches the order at the time of supply. Therefore, it is suitable for adopting a mechanism in which the serial numbers of banknotes supplied from the banknote supply means 30 are sequentially read one by one, and recorded and utilized in the order of transportation.

Further, when a predetermined number of banknotes have been accumulated in the first accumulation tray 51, the first accumulation tray 51 is retracted to the rear of the banknote accumulation area, and the second accumulation tray 71 has been retracted outside the banknote accumulation area until then. Can be rotated to shift to the accumulation position P4. Therefore, the banknote bundle BB1 on the first accumulation tray at the evacuation position P2 can be separated from the banknote bundle BB1 and continuously accumulated on the second accumulation tray 71 without immediately taking out the banknote bundle BB1. it can. Stopping the supply of banknotes to the impeller and the discharge of banknotes from the impeller to the banknote collection area takes less than about 1 second to lower the second collection tray 71 while retracting the first collection tray 51. Since it is only a degree, the interruption time is shortened, and it becomes possible to efficiently carry out the counting work of a large amount of banknotes.
On the other hand, the conventional paper sheet counting device cannot continue the next collecting operation unless the paper sheet bundle discharged to the take-out position is taken out after the accumulation is completed. That is, conventionally, the device has been stopped unless the bundle of paper sheets accumulated in advance is taken out. On the other hand, in the present invention, the stacking operation can be resumed by waiting for an extremely short time required for the stacking trays to be replaced without taking out the bundle of paper sheets. By stopping the paper leaf discharge operation and the like and then restarting the paper leaf discharge operation and the like in this way, the counting and accumulation processing can be restarted with only the minimum necessary interruption time. Therefore, workability can be significantly improved.

In the present embodiment, since the two

accumulation trays

51 and 71 that operate individually and move in and out of the accumulation positions P1 and P4 are provided, it is possible to simultaneously accommodate two banknote bundles BB1 and BB2, and the preceding embodiment. Even when the accumulated banknote bundle BB1 exists in the inner part of the accumulation area SA, the next banknote bundle BB2 can be accumulated on the banknote accumulation area side in parallel. Therefore, it is possible to secure a time allowance for the worker to perform other related work such as taking out a bundle of banknotes and strapping them during the counting work. Further, since two predetermined number of banknote bundles can be accumulated at the same time by one device configuration, it is not necessary to provide a plurality of collecting devices (stackers), and the size and cost of the devices are not increased.
The bill accumulation area SA is configured to have a large capacity so that a large amount of bills can be accumulated, and the two-segment accumulation mode and the large capacity accumulation mode described later can be arbitrarily selected according to the capacity of the accumulated bills desired by the user. it can. Therefore, it can be used flexibly according to the purpose of operation without wasting space. In the two-segment accumulation mode, the previously accumulated banknote bundle BB1 is retracted in the inner part of the banknote accumulation area that also functions for large-capacity accumulation, so that the storage space is not wasted.

[1-3: Integration operation in large-capacity integration mode]
Next, FIGS. 11 (a) to 11 (f) and 12 (g) to (j) are diagrams for explaining the accumulation operation and the accumulation method in the large-capacity accumulation mode by the bill counting device, and FIG. 13 is the accumulation operation. , It is a flowchart relating to the accumulation method. The same parts as those of the stacker unit of FIG. 6 are designated by the same reference numerals, and the description of overlapping configurations and operations will be omitted.

The configuration of the banknote counting device 1 of this example is the same as that of the banknote counting devices of FIGS. 6 to 9, and when the user wishes to collect a large amount of banknotes, the large-capacity collection mode is performed using only the first collection tray 51. Perform continuous accumulation. Although the third bill presence / absence detection sensor S3 (effective element S3E, light receiving element S3R) is not shown in FIGS. 6 to 9, it is actually equipped. Further, the first and second bill presence / absence detection sensors S1 and S2 shown in FIGS. 6 and 6 are actually equipped although they are not shown in FIGS. 11 and 12.
FIG. 11A shows a standby state, and the banknote supply / transport means 30, 100, and the impeller 10 are in a stopped state. The first accumulation tray 51 is stopped at the accumulation position P1 which is the initial position. The distance L between the front surface of the first stacking tray and the impeller 10 at this time is a distance suitable for receiving the banknotes discharged from the impeller on the first stacking tray in an optimum state. If the first accumulation tray is retracted too far into the inner part of the bill accumulation area SA to the extent that the interval L exceeds the appropriate value, it is released from the impeller until it lands on the first accumulation tray. As the time required for the banknotes becomes longer, the banknotes are dropped and the accumulation is disturbed. If the accumulated state of the accumulated banknotes is scattered and becomes unaligned, it takes time and effort to take out the accumulated banknotes and then arrange them, which is a burden on the operator and leads to a decrease in counting work efficiency.

On the contrary, when the first accumulation tray is too close to the impeller so that the interval L is less than the appropriate value, the previously accumulated banknotes and the succeeding banknotes interfere with each other to transport the succeeding banknotes. Inhibits. When the situation becomes further worse, the bundle of already accumulated banknotes on the first accumulation tray presses on the impeller, deforms the outer shape of the impeller slightly, and causes the banknotes to fall off during transportation. Poor accumulation poses a risk of losing banknotes inside the device, leading to miscalculation.
Since the value of the interval L as an appropriate value has a predetermined margin, a predetermined number of banknotes, for example, 100 banknotes, are continuously accumulated in an appropriate posture at each accumulation position of the first accumulation tray. Can be done.

The effective element S3E and the light receiving element S3R constituting the third bill presence / absence detection sensor S3 are arranged so as to face each other via the gap provided in the back plate 54 of the first integrated tray, so that the detection light transmitted through the gap causes the first. 1 Detects the presence or absence of banknotes on the accumulation tray.
In the present embodiment, when the first integrated tray 51 is in the initial position shown in FIG. 11 (a), the impeller starts rotating as shown in (b) and the impeller as shown in (c) and (d). One by one, the banknotes are discharged onto the first accumulation tray.
When a predetermined number of banknotes on the first accumulation tray, for example, 100 sheets are accumulated, the first accumulation tray motor 61 moves the first accumulation tray to the rear of the banknote accumulation area by a predetermined distance L1 as shown in (e). .. Further, when 100 sheets are accumulated, the first accumulation tray is moved to the rear of the bill accumulation area by a predetermined distance L1 as shown in (f). This accumulation operation is repeated until the final banknote as shown in FIG. 12 (g).
During this time, the width at which the first stack tray is retracted is adjusted so that the distance L between the banknotes and the impeller on the first stack tray maintains the optimum value (allowable range) regardless of the increase in the number of stacks.

Next, an integration operation procedure in the large-capacity integration mode will be described based on the flowchart of FIG.
In step S20, a predetermined small number (unit number), 100 banknotes in this example, passes through the banknote count sensor CS in a state where the impellers shown in FIGS. 11B, 11C, and 11D have started to rotate. Check if you did. When the 100th sheet has passed and is accumulated on the first accumulation tray as shown in FIG. 11 (e), the first accumulation tray faces the rear in the bill accumulation area SA by a predetermined distance L1 in step S21. The first integrated tray motor 61 is driven so as to retract. During this period, the impeller 10 continues to rotate to continue the accumulation on the first accumulation tray without interruption (FIG. 11 (f)).
In step S22, it is checked whether or not the next 100 sheets, that is, the 200th sheet is accumulated on the first accumulation tray, and if it passes, the first accumulation tray is further determined backward in the bill accumulation area SA. The first integrated tray motor 61 is driven so as to retract by a distance L1 (step S23). During this period, the impeller 10 continues to rotate to continue the accumulation on the first accumulation tray without interruption.

After that, by repeating the same operation, that is, retracting and accumulating only the distance L1 of the first accumulating tray, the accumulation completed state shown in FIG. 12 (g) is achieved. BBn indicates a large number of banknote bundles that have been collected. In step S24, it is checked whether or not the target collection of all banknotes is completed, and if the collection is completed, the impeller motor 21, the banknote supply / transport means 30, and 100 are stopped. At this stage, the accumulated banknote bundle BBn is taken out from the take-out opening provided in the casing 85 (FIG. 12 (h)).
In the following step S26, it is checked whether or not the third banknote presence / absence detection sensor S3 detects the banknote, and if the banknote is detected, the banknote is waited for extraction (step S27), and if the banknote is not detected. Moves the first stacking tray to the home position (FIG. 11 (a), stacking position P1) (step S28), restarts the rotation of the impeller motor (step S29), and starts from the state shown in FIG. 11 (b). Start agglomeration.
As described above, according to the bill counting device 1, while the large-capacity bill collecting area SA can be used to collect the bills in two categories, it is also possible to collect the large-capacity bills. In the large-capacity integration mode, the distance L between the first accumulation tray and the impeller that retracts the first accumulation tray by a predetermined distance L1 each time a predetermined number of units is accumulated can always be maintained at an appropriate value, and even a large number of sheets can be continuously used. Therefore, it becomes possible to stably accumulate.

In the present invention, the first stack tray that enables large-capacity accumulation and the second stack tray that enables two-segment accumulation are provided, so that one stacker unit can be used for large-capacity banknote accumulation and two categories according to the user's choice. Any of the accumulation can be carried out arbitrarily. Even if the user wants to collect a predetermined small number of sheets, it can be operated without wasting the collection space.
In addition, the two-segment accumulation mode and the large-capacity accumulation mode can be selected according to the capacity of the accumulated banknotes desired by the user, and the space can be utilized without wasting space according to the operation, and it can be flexibly handled.

[1-4: Modification example]
Next, FIGS. 14A and 14B are diagrams showing a configuration example when a plurality of stacker units are connected in the bill counting device according to the first embodiment. In addition, the basic configuration of the bill counting device of FIGS. 1 to 5 and the basic configuration of the stacker unit of FIG. 6 are also referred to, and the same parts as those of the first embodiment are designated by the same reference numerals, and the overlapping configurations and the overlapping configurations and The description of the operation is omitted.
As described with reference to FIG. 1, the bill transport path 100 of the bill counting device 1 is provided with a branch transport path 100b extending in parallel with the regular transport path on the upstream side of the regular transport path 100a. The branch transport path 100b is branched from the path toward the regular transport path 100a by the first gate 120, and extends rearward along the upper part of the impeller and the accumulation tray.

FIG. 14A shows a state in which the second stacker unit SU2 is connected to the side surface (outside of the take-out area 80) of the first stacker unit SU1 which is always provided in the bill counting device 1. The details of the connecting mechanism will not be described, but it will be configured so that it can be connected by screwing or the like. The configurations of the first stacker unit SU1 and the second stacker unit SU2 are almost the same. As shown in the figure, when the two stacker units are connected, the discharge unit 100b'provided at the end of the branch transfer path 100b inside the first stacker unit SU1 is provided at the start end of the branch transfer path 100b of the second stacker unit SU1. It is configured so that the banknotes that have been conveyed in communication with the receiving unit 100b "can be smoothly transferred. The discharging unit 100b'is also provided at the end of the branch transfer path 100b of the second stacker unit SU2. Therefore, other stacker units can be connected.
According to the apparatus configuration shown in FIG. 14A, even if the first and second

accumulation tray portions

51 and 71 of the first stacker unit SU1 are both filled with the accumulated banknote bundles, until then. By switching the first gate 120, which has opened the regular transport path 100a, to open the branch transport path 100b, the second stacker unit SU2 is used to count the subsequent bills without taking out each bundle of bills. , It becomes possible to continue the accumulation. Therefore, it is possible for the worker to secure a longer time allowance for performing the accompanying manual work accompanying the counting of the straps and the like.

The reject unit 130 may be provided only in the first stacker unit SU1, and it is not necessary to provide the reject unit 130 in the stacker units SU3, ... After the second stacker unit SU2 for connection.
Since the second stacker unit SU2 and the other stacker units SU3 and SU4 for connection shown in FIG. 14B have the same configuration, any number of stacker units SU3 and SU4 can be connected as shown in the drawing.
Since the stacker unit itself is miniaturized, the occupied area does not become so large even if a plurality of units are connected.

<Second Embodiment>
Next, FIGS. 15 (a) to 15 (g) are views showing the internal configuration and operation procedure of the bill counting device according to the second embodiment. FIGS. (A) to (e) show the integration operation in the two-segment integration mode, and FIGS. (F) and (g) show the integration operation in the large-capacity integration mode. In addition, the basic configuration of the bill counting device of FIGS. 1 to 5 and the basic configuration of the stacker unit of FIG. 6 are also referred to, and the same parts as those of the first embodiment are designated by the same reference numerals, and the overlapping configurations and the overlapping configurations and The description of the operation is omitted.

The bill counting device 1 according to the second embodiment is different from the first embodiment in that the impeller 10 is arranged in the upper part of the casing 85 and the blades are directed toward the bill collecting area SA arranged below the impeller. The point is that the banknotes are discharged downward from the car. In other words, in the first embodiment, the banknotes are accumulated and stacked in the horizontal direction, but in this example, the banknotes are accumulated in the vertical direction. Further, the first accumulation tray 51 moves in the vertical direction in the banknote accumulation area SA in an inclined posture in which banknotes can be accumulated. The second collection tray 71 is configured to freely appear and disappear in the bill collection area by a rotating shaft 73 provided on the inner wall (inner wall facing the impeller) of the bill collection area SA. At the retracting position P3, the second stacking tray 71 retracts upward at a position facing the impeller laterally with respect to the rotation shaft 73, and at the stacking position P4, the second stacking tray 71 is approximately 90 degrees toward the inside of the bill stacking area. It rotates and maintains a posture parallel to the first stack tray. In this example, when each stacking tray is in the stacking position, the bills are tilted as shown in the drawing so that the bills to be piled up can be gathered downward in the tilting direction.

Various processes as a premise for starting counting of passing bills in FIG. 15A are the same as those in the first embodiment.
The integration operation in the two-segment integration mode will be described with reference to FIGS. 15A to 15E.
FIG. 15A shows a state immediately before the first bill B1 sent into the regular transport path 100a reaches the impeller. By starting to drive the impeller motor 21 in this state, as shown in FIG. 15B, the banknotes sent to the outer periphery of the impeller are sequentially inserted into the banknote holding vacant spaces 17. At this time, the number of banknotes passed by the banknote count sensor CS is counted.
FIG. 15C shows a state in which a predetermined number of 100 banknotes BB1 have been accumulated on the first accumulation tray 51, and after the last 100th banknotes have been accumulated on the first accumulation tray 51. The impeller 10 is stopped at, and the bill supply by the bill supply means 30 and the transport by the bill transport path 100 are also stopped. Further, the first accumulation tray 51 is lowered to the retracted position P2.
In FIG. 15D, the second accumulation tray 71 is rotated 90 degrees from the retracted position P3 (home position) and moved to the accumulation position P4 (banknote accumulation area SA). At this point, since the first accumulation tray 51 has already moved to the evacuation position P2, the second accumulation tray 71 is directly facing the impeller 10 and is in a state where the discharged banknotes can be sequentially received. ..
In FIG. 15E, after the first banknote presence / absence detection sensor S1 (not shown) confirms that no banknotes exist in the upper part of the banknote accumulation area SA, the banknotes are fed by the banknote supply means 30 and the banknotes are transported by the banknote transport path 100. Is restarted, and after the impeller count sensor CS detects the entry of banknotes, the impeller rotation is restarted. By stopping the rotation of the impeller when the number of accumulated banknotes on the second accumulation tray 71 reaches a predetermined number, the accumulation divided into two categories is completed, and the accumulated banknote bundles BB1 and BB2 on each accumulation tray are separated. After taking it out, the impeller can resume the release of banknotes.

In this configuration example, new banknotes are not delivered and conveyed from the completion of the accumulation of 100 banknotes in the first accumulation tray 51 until the first accumulation tray 51 is retracted from the accumulation position P1. However, since this interruption time stays within 1 second, the overall processing speed is not significantly delayed even when high-speed counting processing of about 15 sheets / second is required.
Also in the present embodiment, it is possible to appropriately adjust the stop position of the first accumulation tray in order to pressurize the banknote bundle on the first accumulation tray with the second accumulation tray as in the first embodiment. ..

Next, the integration operation in the large-capacity integration mode will be described with reference to FIGS. 15 (a), (b), (f), and (g).
In FIGS. 15A and 15B, the first stacking tray 51 is located at the stacking position P1 closest to the impeller 10, but in FIG. 15F, the number of stacking trays reaches a predetermined unit number, or 100 in this example. At that time, the first accumulation tray 51 is lowered by a predetermined distance L1. This lowering operation is performed every time the number of accumulated banknotes increases by 100, and as shown in (g), the drive of the impeller or the like is stopped when the accumulation of all banknotes is completed.
Since the processing procedure for counting and accumulating is based on the flowcharts of FIGS. 10 and 13, the description thereof will be omitted.
In the two-segment accumulation mode, even after a predetermined number of sheets have been accumulated in the first accumulation tray 51, the subsequent banknotes can be processed while shortening the time for interrupting the processing, so that the processing efficiency of the banknotes can be improved. Further, since two predetermined number bundles BB1 and BB2 can be integrated at the same time by one stacker unit SU, it is not necessary to provide a plurality of stacker units, and it is possible to prevent an increase in size and cost of the apparatus. Further, it is possible to stably and surely separate a predetermined number of banknote bundles and subsequent banknote bundles without causing troubles such as banknote jam in the impeller. Further, the banknotes can be accumulated in the order in which they have been transported.

In addition, the two-segment accumulation mode and the large-capacity accumulation mode can be selected according to the capacity of the accumulated banknotes desired by the user, and the space can be utilized without wasting according to the operation purpose, and it can be flexibly dealt with.
A configuration for connecting a plurality of stacker units SC shown in FIG. 14 can also be applied to the present embodiment.

<Third Embodiment>
Next, FIGS. 16A to 16G are diagrams showing the internal configuration and operation procedure of the banknote counting device according to the third embodiment. FIGS. (A) to (e) show the integration operation in the two-segment integration mode, and FIGS. (F) and (g) show the integration operation in the large-capacity integration mode. The basic configuration of the bill counting device of FIGS. 1 to 5 and the basic configuration of the stacker unit of FIG. 6 are also referred to, and the same parts as those of the first embodiment and the second embodiment are designated by the same reference numerals. The description of the duplicated configuration and operation will be omitted.

Hereinafter, the differences from the second embodiment will be mainly described.
The bill counting device 1 according to the third embodiment differs from the second embodiment in the shape of the second accumulation tray 71, the height position when the second accumulation tray moves to the accumulation position P4, and the posture.
The second accumulation tray 71 of the third embodiment is centered on the rotation shaft 73 provided on one side wall 86 of the bill accumulation area SA, from the retracted position P3 in FIG. 16A to the accumulation position P4 in FIG. 16D. Although it rotates, at the accumulation position P4, the tip of the second accumulation tray is locked to the other side wall 87, so that it is not parallel to the first accumulation tray 51 at the evacuation position P2, and the bill accumulation area. It is locked with the upper opening of the. Moreover, the upper surface of the second accumulation tray is an inclined surface.
Therefore, as shown in FIG. 16E, the banknotes discharged from the impeller are collected in a substantially vertical posture supported by the inclined upper surface of the second accumulation tray 71 and the upper part of the side wall 86. The posture of the accumulated banknote bundle BB2 on the second accumulation tray 71 is a state in which the upper end side is inclined in a direction away from the impeller and leans against it, and the accumulated banknote bundle BB1 on the first accumulation tray 51 lies on its side with a gentle inclination. Although it is different from the posture, there is no problem in workability when taking it out.

The points other than the above, that is, the operations of the

integrated trays

51 and 71 in the two-segment integrated mode and the operations of the

integrated trays

51 and 71 in the large-capacity integrated mode are the same as those in the second embodiment. The point that the two-segment integration mode shown in FIGS. 15 (c), (d) and (e) and the large-capacity integration mode shown in FIGS. 15 (f) and 15 (g) can be arbitrarily selected, and other effects. Is the same as in the second embodiment.
Since the processing procedure for counting and accumulating conforms to the flowcharts of FIGS. 10 and 13, the description thereof will be omitted.
A configuration for connecting a plurality of stacker units SC shown in FIG. 14 can also be applied to the present embodiment.

<Fourth Embodiment>
Next, FIGS. 17A to 17D are explanatory views showing an internal configuration of the bill counting device according to the fourth embodiment and a two-segment accumulation operation procedure. The basic configuration of the bill counting device of FIGS. 1 to 5 and the basic configuration of the stacker unit of FIG. 6 are also referred to, and the same parts as those of the first to third embodiments are designated by the same reference numerals, and the overlapping configurations are described. And the description of the operation is omitted.

Hereinafter, the differences from the respective embodiments will be mainly described.
The difference between the bill counting device 1 according to the fourth embodiment and the above-described embodiments is the shape and operation of the bottom plate 140 and the back plate 150 constituting the integrated tray device 50.
The bottom plate 140 and the back plate 150 are orthogonal to each other in a T-shape, and the motors constituting the drive mechanism (not shown) centering on the common rotation shaft 141 are used to show the first integrated posture shown in FIG. It rotates forward and reverse within a range of 90 degrees with and from the second integrated posture shown in d).
The bottom plate 140 constitutes a first accumulation tray between the upper surface 142 of the bottom plate and the front surface of the back plate 150, and the first accumulation tray faces the impeller 10 at the accumulation position P1 shown in FIG. 17A. ing. Therefore, the banknotes discharged one by one from the impeller can be received and accumulated.

Further, in the bottom plate 140, the bottom plate bottom surface 143 faces the impeller 10 in the state after being rotated 90 degrees as shown in FIG. 17 (c), and one sheet from the impeller with the inner bottom surface 85a of the casing 85. Banknotes that are released one by one can be received and accumulated. The bottom surface 143 of the bottom plate and the bottom surface 85a inside the casing form a second accumulation tray.

Next, the integration operation will be described.
FIG. 17A shows a state immediately before the first bill B1 sent into the regular transport path 100a reaches the impeller. By starting to drive the impeller motor in this state, the banknotes sent to the outer periphery of the impeller are sequentially inserted into the banknote holding vacant spaces 17. At this time, the number of banknotes passed by the banknote count sensor CS is counted.
FIG. 17B shows a state in which a predetermined number of 100 banknotes BB1 have been accumulated on the first accumulation tray formed by the upper surface 142 of the bottom plate and the front surface of the back plate 150, and the final 100th sheet. After the banknotes are accumulated in the first accumulation tray, the impeller 10 is stopped, and the banknote supply by the banknote supply means 30 and the banknote transport path 100 shown in FIG. 1 are also stopped.
FIG. 15C shows a state in which the stacking tray device 50 is rotated 90 degrees counterclockwise, and a second stacking tray composed of a bottom plate bottom surface 143 and a casing inner bottom surface 85a is facing the impeller 10. .. Therefore, the discharged banknotes can be sequentially received in the second accumulation tray. The banknote bundle on the second accumulation tray can be taken out of the casing from an outlet (not shown).
At this point, the accumulated banknote bundle BB1 in the first accumulation tray is retracted from the accumulation position P1 and is located in the banknote take-out area 89 which is a space behind the casing 85, and is outside from an outlet (not shown) provided in the casing. Can be taken out to.

Since the banknote stacking operation in the second stacking tray can be continued even if the banknote bundle BB1 held in the first stacking tray is not taken out and is held by the first stacking tray, the bills are divided into two categories. Separate accumulation can be carried out.
By stopping the rotation of the impeller when the number of accumulated banknotes on the second accumulation tray reaches a predetermined number, the accumulation divided into two categories is completed, and the accumulated banknote bundles BB1 and BB2 on each accumulation tray are taken out. After that, the impeller can resume the release of banknotes.

In this configuration example, new banknotes are not delivered and transported from the completion of the accumulation of 100 banknotes in the first accumulation tray until the first accumulation tray is retracted from the accumulation position P1. However, since this interruption time stays within 1 second, the overall processing speed is not significantly delayed even when high-speed counting processing of about 15 sheets / second is required.

<Summary of composition, action, and effect of the present invention>
The paper leaf processing device 1 according to the first aspect of the present invention is a paper leaf that holds a plurality of blades 15 that protrude radially around a rotation shaft 11 and a single paper leaf that is formed between adjacent blades and is received. An impeller 10 having a holding space 17 and sequentially discharging a sheet of paper leaf B held in each paper leaf holding space when rotating to a predetermined accumulation area SA, and each paper leaf holding space of the rotating impeller Paper leaf supply and transporting

means

30 and 100 that supply paper sheets one by one in the facility, and a stacking tray device that is arranged in the accumulation area and holds the paper sheets discharged from each paper leaf holding space one by one in a stacked state. A paper leaf processing device including 50, drive

mechanisms

60 and 80, and control means 200 for controlling the drive mechanism. The stacking tray device is a paper leaf stacking position (paper leaf receiving posture) facing the impeller. ), The first stacking tray 51 and the first stack tray 51 are moved from the stacking position to the retracted position when the number of stacking paper sheets reaches a predetermined number. When the stacking tray is in the paper leaf accumulation position, it is in the retracted position retracted from the paper leaf accumulation position (advance / retreat path of the first accumulation portion), while when the first accumulation tray is moved to retract or in the process of moving. The second stacking tray 71, which moves to the paper leaf accumulation position and collects the discharged paper sheets, and is rotated to the retracted position when a predetermined number of accumulated paper leaf bundles are taken out, is provided. The first stacking tray is in the retracted position, and the second stacking tray is in the leaf stacking position, so that the stack of paper sheets can be taken out to the outside.
Paper sheet counting devices tend to increase the accumulation space. However, for users who desire processing in units of a small number of sheets, most of the large space due to the large capacity is wasted, which causes the device to become larger than necessary. That is, the counting device for a large number of sheets could not cope with the accumulation of a small number of sheets, and the counting device for a small number of sheets could not cope with the accumulation of a large number of sheets.

In the present invention, such conflicting requirements can be satisfied at the same time.
That is, the paper leaf counting device 1 is a two-segment accumulation mode in which a predetermined number of sheets of paper discharged from the impeller are accumulated on each accumulation tray by alternately moving the two

accumulation trays

51 and 71 to the accumulation position. And, it is possible to realize a large-capacity integration mode using only the first integration tray, which will be described later.

In the two-segment accumulation mode, an accumulation tray device 50 having a plurality of

accumulation trays

51 and 71 for accumulating the paper sheets discharged one by one from the impeller is arranged in the paper leaf accumulation area SA, and the first accumulation tray 51 Is in the stacking position, the second stacking tray 71 is in the retracting position, and when the second stacking tray is in the stacking position, the first stacking tray is in the retracting position. That is, the paper leaf accumulation area is divided into two by the second accumulation tray. Therefore, immediately after the accumulation of one accumulation tray is completed and the paper is moved to the evacuation position, the accumulation of paper sheets can be started immediately on the other accumulation tray. As a result, the processing interruption time is short, and the previously accumulated paper bundle and the subsequent accumulated other paper bundles can be separated and accumulated.
Even after one of the stacking trays holding the stack of paper strips is moved to the retracted position, the subsequent paper strips can be processed while shortening the time for interrupting the processing, so that the counting of paper sheets and the stacking processing efficiency can be improved as a whole. .. Not only is the complexity reduced because the user can continue counting and stacking without having to immediately remove the stack of paper from one tray, but the process continues as long as the stack of paper on one tray is removed. it can.

In recent years, improvement in processing efficiency has been desired in paper sheet counting devices, and it is necessary to shorten the waiting time such as temporary interruption of processing due to waiting for extraction of a bundle of accumulated paper sheets. However, the present invention solves this problem. can do.
Since two sets of a predetermined number of paper leaf bundles can be stacked at the same time by one stacking tray device, it is not necessary to provide a plurality of stacker units, and the size and cost of the device do not increase.

In addition, it is possible to stably and surely separate a predetermined number of paper strips and subsequent paper strips without causing troubles such as jams between the blades of the impeller.
Further, since the paper sheets can be accumulated on the accumulation tray in the order of being supplied and conveyed by the paper sheet supply means 30 and 100, the reading order information of the serial number obtained by carrying out the paper leaf feeding is obtained. The stacking order in the stacking paper bundle can be the same.
Since one impeller can be used to form two bundles of accumulated paper and two bundles can be held in the device at the same time, the stacker function for two units can be realized with one device configuration, and the number of parts is large. The size of the device can be reduced.
In the large-capacity accumulation mode, while holding the second accumulation tray in the retracted position, integration is performed only by the first accumulation tray.
The stacking direction of the banknotes may be a horizontal direction (diagonal horizontal direction) as in the first embodiment, or a vertical direction as in the second and third embodiments.

In the second paper leaf processing apparatus according to the present invention, in the control means 200, the control means 200 has the first stacking tray 51 holding the stack of paper sheets in the retracted position and the second stacking tray 71 not holding the stacking paper leaves. It is characterized in that the paper leaf is discharged from the impeller to the second stacking tray when the paper leaf is in the paper leaf accumulation position.
Therefore, the accumulation on the second accumulation tray can be continuously carried out without taking out the accumulation paper leaf bundle on the first accumulation tray.

In the third paper leaf processing apparatus according to the present invention, the position of the first stacking tray when the second stacking tray moves to the paper leaf stacking position is stacked in the first stacking tray by the second stacking tray. It is characterized in that the bundle of paper sheets is set to be pressurized.
If the position in the front-rear direction of the first stacking tray is adjusted so as to compress the stack of paper bundles accumulated in the first stacking tray by moving the second stacking tray to the stacking position of the paper strips, the bundle of paper sheets is assumed to be at the time of design. Even if it swells in the thickness direction more than expected, it can be stably accumulated because the bundle of paper sheets is compressed and crushed by the second accumulation tray.

In the paper leaf processing apparatus according to the fourth aspect of the present invention, the control means 200 uses the stacking paper on the first stacking tray when the first stacking tray is in the leaf stacking position and the second stacking tray is in the retracting position. It is characterized in that the distance between the first accumulation tray and the impeller is increased by retracting the first accumulation tray as the number of leaves increases.
In the large-capacity accumulation mode, only the first accumulation tray is arranged at the paper leaf accumulation position, and all the paper sheets discharged from the impeller are accumulated by the first accumulation tray. Since it is necessary to properly maintain the distance between the impeller and the stack of paper sheets, the first stacking tray is appropriately retracted at a predetermined timing as the number of sheets of paper to be collected increases. By increasing the distance between the first stacking tray and the impeller, the distance between the upper surface of the stack of paper sheets on the first stacking tray and the impeller can be kept constant.

In the fifth paper leaf processing apparatus according to the present invention, the control means holds only one sheet of paper, which has been supplied one by one from the paper leaf supply and transporting means, in one paper leaf holding space. It is characterized in that the paper leaves discharged from the leaf holding vacant space and accumulated in the first accumulation tray or the second accumulation tray are arranged in the order of supply by the paper leaf supply and transport means.
Paper leaf holding A single sheet of paper held in the empty space is always discharged to the accumulation area while the impeller is rotating 360 degrees, and does not return to the paper leaf supply position 100A after the rotation. Therefore, a plurality of paper sheets are not accommodated in one paper leaf holding space.
Paper leaves are held in each paper leaf holding space 17 in the order in which they were sent, and the held paper leaves are collected in the same order as they were sent in the process of rotating the impeller. Since it is discharged to the supply and accumulated, it can be accumulated on the accumulation tray in the order of supply by the paper leaf supply means.

In the sixth paper leaf processing apparatus according to the present invention, a paper leaf holding space for holding a plurality of blades radially protruding around a rotation axis and a single paper leaf formed between adjacent blades and received. It is equipped with a paper leaf processing device equipped with an impeller that sequentially discharges one sheet of paper held in each paper leaf holding space when rotating to a predetermined accumulation area, and is arranged in the accumulation area to each paper. A stacking tray device 50 that collects the paper leaves released from the leaf holding vacant space one by one. The stacking tray device is a stacking tray device facing the impeller and the paper leaf stacking position (rearward). The first stacking tray 51 that moves back and forth between the retracted retracted position and the first stacking tray are in the retracted position retracted from the leaf stacking position (advance / retreat path of the first stacking portion) when the first stacking tray is in the leaf stacking position. On the other hand, it is characterized in that it includes a second accumulation tray 71 that is rotationally moved to the paper leaf accumulation position when the first accumulation tray moves to the retracted position or in the process of moving.
This integrated tray device corresponds to the first integrated tray device according to the present invention, and when incorporated into the paper sheet processing device 1, it exerts the action and effect corresponding to the first invention.

In the seventh method of collecting paper sheets by the paper sheet processing apparatus according to the present invention, when a predetermined number of sheets of paper have been accumulated in the first accumulation tray at the sheet sheet accumulation position, the paper sheet feeding operation by the paper leaf feeding and transporting means is performed. , And the step of stopping the paper leaf discharge operation by the impeller, the step of moving the first stacking tray to the retracted position, and the step of moving the second stacking tray to the paper leaf stacking position, and the second stacking tray of paper leaf stacking. It is characterized by including a step of resuming the paper leaf supply operation and the paper leaf discharge operation when the user moves to the position.
According to this paper leaf accumulation method, by stopping the paper leaf discharge operation, etc., and then restarting the paper leaf discharge operation, etc., counting and accumulating processing can be resumed with only the minimum necessary interruption time. Can be done.
The conventional paper sheet counting device cannot continue the next collecting operation unless the paper sheet bundle discharged to the take-out position is taken out after counting and accumulating. However, in the method of the present invention, the paper sheet bundle is not taken out. However, the stacking operation can be resumed by waiting for an extremely short time required for the stacking tray to rotate.

In the paper leaf accumulation method using the paper sheet processing apparatus according to the eighth aspect of the present invention, when the second accumulation tray moves to the paper leaf accumulation position, the second accumulation tray is accumulated in the first accumulation tray. It is characterized by pressurizing.
According to this, since the bundle of paper sheets accumulated in the first accumulation tray is compressed by the second accumulation tray as in claim 3, even if the bundle of paper sheets expands in the thickness direction beyond the expectation at the time of design. Since the paper leaf bundle is compressed and crushed by the second accumulation tray, the effect of stable accumulation can be obtained.
