Description

[Detailed description of the invention] For example, in a banknote sorting machine, the present invention takes out banknotes supplied to a supply section one by one, stacks them in a predetermined stacking device to be stored, and separates them into a predetermined number of banknotes. The present invention relates to a stacking device for paper sheets that is arranged by hand.

Conventionally, for example, a stacking device for a banknote sorting machine has a stacking box provided with a vertically movable mounting plate, and a separator located above the mounting plate that can rotate and move in the front and rear directions. is located. That is, the banknotes that have been counted and conveyed one by one are sequentially stacked on a separator that is placed on standby above the placement plate. When the number of banknotes that can be accumulated on the separator reaches a predetermined number, for example 100, the separator rotates, so that the 100th banknote and the 101st and subsequent banknotes are separated. be separated into After that, the 100 banknotes on the placement plate are taken out from the accumulation chamber, and the separator leaves the accumulation chamber, so that the banknotes on the separator fall under their own weight and are stored on the placement plate. Therefore, the separator is moved forward again and returned to the upper position of the stacking chamber, and then when 100 banknotes are stacked on the mounting plate, it waits to separate it from the 101st and subsequent banknotes. It's summery.

However, in such a stacking device, if the intervals between banknotes being conveyed are narrow,
Even if the separator was activated at the same time as the banknotes fell and accumulated on the placement plate, the separation from the following paper sheets was not ensured.There was a problem that reliable counting accuracy could not be obtained. .

The present invention was developed in view of the above circumstances, and its purpose is to separate paper sheets into a predetermined number of sheets in a collection box, and to stack them in an arranged manner.
Moreover, it is an object of the present invention to provide a paper sheet stacking device that automatically detects that the stacked paper sheets have been reliably separated into a predetermined number of sheets.

The present invention will be explained below based on an embodiment shown in FIGS. 1 to 5. Fig. 1 shows an outline of this device. In the figure, 2 is a suction/take-out roller that sucks and takes out paper sheets, such as bank notes P... one by one, supplied to the supply section 1. The banknotes P are conveyed while being held between conveyor belts 3a and 3b, and pass through detection devices 4A and 4B. The banknotes P are configured to be fed into the stacking devices 6A, 6B and the pocket 7 via the gate devices 5A, 5B, respectively, based on the detection results of the detection devices 4A, 4B.

Next, FIGS. 2 to 4 show an integrated device. In the figure, 10 is a detection device that emits a signal when a bank note P conveyed from the direction of arrow A passes.
It is held between a pair of feed rollers 11a and 11b and fed into the apparatus. A static electricity removing device 12 is attached to the feed roller 11b, and this static electricity removing device 12 removes the charge on the bank note P to prevent erroneous separation.

In this case, when transporting banknotes P of a predetermined size, it is necessary to make the storage capacity within the stacking device variable so as to match the size, and in particular, to stack the banknotes in alignment within the device.

Therefore, when the handle 13 shown in FIG. 3 is rotated in the direction of the arrow to adjust it to a predetermined size, the slide stopper 15 shown in FIG. Sa is obtained. At the same time, as the cam 16 fixed to the slide stopper 15 moves in the direction of arrow X, the cam follower 17 moves in the direction of arrow Y.

The cam follower 17 and the hinges 18, 18 shown in FIG. 5 are fixed to a block that slides on a shaft 19. The hinge 18 is attached to a door 20 made of synthetic resin as shown in FIG. 5, and is moved in the direction of arrow Y by rotating the handle 13.

Further, 21A is a diaphragm A that vibrates in the direction of arrow Y, and 21B is a diaphragm B that vibrates in the direction of arrow X.
It serves to align the banknotes P accumulated in the accumulation device. Further, 22 is an eccentric cam mounted on the motor 23, and 24a and 24b are cam followers. By driving the motor 23 and rotating the eccentric cam 22, the diaphragm A 21A and the diaphragms B and 21B are simultaneously activated by the cam follower 24a, 2
4b. In FIG. 2, the slide stopper 15 and door 20 are rotated by rotating the handle 13, but it is also possible to move the diaphragms A and 21A at the same time. That is, the diaphragm A,2
Brackets 25a, 25b supporting the fulcrum of 1A
The bracket 25 has the same function as the cam 16 for moving the slide stopper 15.
By applying it to a and 25b, it is possible to move in three directions at the same time.

Further, 26 is a disk having a slit (not shown) fixed to the shaft 18a of the handle 13, and 27
is an image sensor disposed to engage with the outer circumference of the disk 26, and when the handle 13 is rotated to match the size desired by the clerk, the banknote P is scanned by a signal from the detection device 10. Since the timing is set in advance, the banknotes P being conveyed always stop at the slide stopper 15.
They are struck by the beats 28, 28 at the same position, and are accumulated in the accumulating device. 29a, 29 in the figure
b is a housing that supports the beats 28, 28 and the slide stopper 1;
5, 15a, 15b are housings 29a, 29
The beats 28, 28 are driven by a rotary solenoid 30 to rotate with a constant stroke.

Further, the slide stopper 15 shown in FIG.
b, 15b move due to the size change, but are positioned downward due to the moving locus of the separator 31 with an R-shaped tip to prevent collision with the bank note P.
This makes the accumulation condition good. On the other hand, the slide stoppers 15a, 15a are always provided above the conveyance path, and prevent the banknotes P knocked down by the beats 28, 28 from scattering outside the stacking device, and detect them. A device 32 is adapted to detect clogging phenomena.

Reference numeral 33 is a vertically movable mounting plate, ie, a back-up, which is located below the separator 31 and accumulates banknotes P. In FIG.
Since the separator 31 is designed to retreat in the direction of the arrow x, the bank note P on the separator 31 is transferred onto the backup 33. Moreover, at this time, the backup 33 is raised to the position shown by the solid line in FIG. 2 and is on standby, so that the banknotes P are transferred from the separator 31 onto the backup 33 while maintaining their alignment.

Then, the separator 31 is rotated counterclockwise, that is, in the direction of the arrow y to change its angle, and then moves forward in the direction of the arrow z and returns to the position shown by the dashed line and waits. .

In this way, when almost a predetermined number of banknotes P are accumulated on the backup 33, the backup 33 descends to the position shown by the dashed line. When a predetermined number of banknotes P are stacked on the backup 33, the separator 31, which is positioned above and stands by, rotates clockwise and stops at the position shown by the solid line. The separator 31 separates the banknotes P that can be stacked on the banknotes 33 from the banknotes P that are subsequently brought in.

Note that the reason why the separator 31 is rotated counterclockwise to temporarily wait at the top level and then rotated clockwise again to lower it to the horizontal position shown by the solid line is to ensure that the separator operates reliably. By this means, the space between the beats 28, 28 and the banknotes P accumulated on the backup 33 is widened, making it easier to separate them. In particular, the stacked banknotes P are struck by the beats 28, 28, thereby shortening the falling time of the banknotes P, and also making it possible to reliably separate the banknotes P regardless of whether they are bent or how strong the banknotes are. .

In this manner, the number of banknotes P accumulated on the backup 33 is counted by the detection device 10.

Next, FIGS. 4 and 5 show a separator and its driving device. In the figure, 35 is a motor, and this motor 35 is directly connected to a separator drive shaft 37 via a coupling 36. Reference numeral 38 denotes a driving roller fitted to the shaft 37. A recess 38a is provided on the outer peripheral surface of the driving roller 38, and the separator 31 is fitted into the recess 38a. ...is now being driven directly.

Further, 39 is an arm rotatable around the shaft 37, and this arm 39 is fixed to a shaft 40. A leaf spring 41 is fixed to the shaft 40, and separator guide rollers 42a, 42b are fixed to the shaft 40.
are pressed together. Furthermore, the separator 31...
A guide roller 42c fixed to the arm 39 is also provided on the lower side of the arm 39, and each of the guide rollers 42a, 42b, and 42c is configured to be rotatable about the shaft 37 together with the arm 39.

A separator stopper 43 is locked to the arm 39, and a pin 44 inserted into the tip of the separator 31 moves to the left as the separator 31 moves back and hits the stopper 43 at the same time. Separator 31 rotates counterclockwise. The rotation of the separator 31 is regulated and locked by a claw 45 engaged with the arm 39 and a claw 48 of a magnet device 47 attached to the pace 46. (See Figure 5)
Note that the arm 39 is always urged downward under the tension of a spring 49.

When the separator 31 is thus locked, the driving roller 38 rotates counterclockwise and moves upward. When the light from the detector 50 is blocked, the driving roller 38
movement is stopped.

Therefore, when the 100th banknote P is detected by the detection device 10, a signal is sent to the magnet device 47 after a certain period of time, so that the separator 31 is released from the locked state.
The tension of the spring 14 causes it to fall.
In particular, when a large number of banknotes are to be processed, the time interval between banknotes becomes short and the separator is required to have high-speed response, so the separator 31...
I used pipes to make it as light as possible.
Note that the shape of the pipe is not limited to a cylindrical shape, but may be non-cylindrical, and in short, the effect can be achieved by forming the pipe in a cylindrical shape.

In this way, the predetermined number of banknotes P separated and accumulated on the backup 33 descends from the position shown by the one-dot chain line in FIG. 2 to the position shown by the two-dot chain line, completing the delivery of the banknotes P. At this time, since the separator 31 is already maintained in a horizontal state, the banknotes P can be aligned and stacked on the separator 31, and furthermore, the banknotes P can be placed on the backup 33 while maintaining the alignment. Predetermined number of banknotes P
can be separated.

Next, the operation of the electric circuit shown in FIGS. 6 and 7,
The timing chart will be explained in detail. A detection device 10 (light emitting element 10
The signal generated by the passage of the banknote P through the light receiving element 10b) is amplified by the amplifier 52 and inputted to the counter 53 and the beat check timing generation circuit 56. This signal is also input to the beat drive circuit 55 via a delay circuit D whose delay time changes depending on the output of the image sensor 27. Counter 5
The output signal of No. 3 is input to the 100-sheet signal input circuit 54. Beat drive circuit 55 drives rotary solenoid 30. The beat check timing generation circuit 56 sends out the beat 28, that is, the bank note P.
The timing to knock down the rotary solenoid 30 (timing to drive the rotary solenoid 30) is the signal “1” at CT1.
Output. At this time, the second detection device 32 (light emitting element 32a, light receiving element 3
The amplifier 59 outputs a signal "0" from the signal generated by the passage of the banknote P in step 2b), and both output signals are input to the AND circuit 65 of the abnormality check circuit 71. At this time, the output of the AND circuit 65 is a "0" signal, and the input of the OR circuit 67 is a "0" signal. On the other hand, beat 28, rotary solenoid 30
After being driven for a predetermined period of time, the beat drive circuit 55 applies a reverse drive to return it to its original position. At this time, the beat check timing generation circuit 56 outputs a signal "1" at this timing CT2. At this time, the banknotes P are knocked down by the series of operations of the beat 28 and are normally stacked inside the stacking device. That is, there should be no trace of the banknote P on the detection device 32 anymore. The output of the detection device 32 and the amplifier 59 is a “1” signal, which is sent to the abnormality check circuit 71.
It is input to the inverter circuit 63 inside. The output of the inverter circuit becomes a “0” signal and this is sent to CT2.
When the signal is input to the AND circuit 66 along with the “1” signal, the output of the AND circuit 66 becomes a “0” signal, which is input to the OR circuit 67. When the beat operation is performed normally, both the input and output of the OR circuit 67 are "0" signals, and the output of the OR circuit 68 is also "0".
Since it is a signal, the abnormality check circuit 71 does not issue an abnormal signal. However, for example, at timing CT1 when the beat 28 is lowered, the bank note P has not yet been conveyed to the predetermined position, that is, the position of the detection device 32, or at timing CT2 when the beat 28 has been returned. If there is an abnormality in which the bank note P or the next bank note is still in the detection device 32, “1” is sent to either the AND circuits 65 or 66.
Since the signal is input, the output of either the AND circuit 65 or 66 becomes "1", the output of the OR circuit 67 also becomes a "1" signal, and the input signal of the OR circuit 68 also becomes "1", resulting in an abnormality. The output of the check circuit 71 becomes "1" and generates an abnormal signal. That is, when a normal beating operation is not performed, this check circuit 71 can detect an abnormality.

On the other hand, when a predetermined number of sheets, for example 100 sheets, have been stacked on the stacking device, the separator drive circuit 57 is activated by the signal output from the 100 sheet signal output circuit 54, and the magnet device 47 is driven, and the separator 31 falls, causing the separator 31 to fall. Separate from subsequent banknotes. At this time, the upper position detector 5 of the separator 31
0 changes from dark to bright, and the separator lower position detector 51 changes from bright to dark. The output signal of the detector 51 is inputted to a separator check timing generation circuit 58 via an amplifier 62. This signal is input to an abnormality check circuit 71. At timing CT3 when the separator 31 is lowered in this way, the separator check timing generation circuit 58 outputs an output signal "1" and inputs it to the AND circuit 69. or
At the timing of CT3, the 100th bank note P is always below the separator lower position (horizontal in this example) due to the separator 31, and the next bank note has yet to pass through the first detection device 10 at the collection entrance. It's when you're doing it. In other words, at this time, there is a state in which there is not even a single bank note inside the stack above the separator 31, so the third detection device 34 (light-emitting element 34a, light-receiving element 34b) provided in the stack is used.
is in a bright state, so the output of the amplifier 60 is “1”
Output a signal. This signal is input to the NAND circuit 70. On the other hand, the outputs of the detector 50 and the amplifier 61 are "1" output signals at this time, which are also input to the NAND circuit 70. Also, the outputs of the detector 51 and the amplifier 62 are "0" output signals at this time, which are input to the inverter circuit 64, and thus input to the NAND circuit 70 which produces a "1" output signal. At this time, the output of the NAND circuit 70 is a "0" output signal, and this signal is input to the AND circuit 69. Therefore, the output of the AND circuit 69 becomes a "0" signal, and the OR circuit 6
Since the input/output signal of 8 is also "0", the abnormality check circuit 71 does not issue an abnormal signal. However, for example,
After the 100th banknote P has been separated by the separator 31, at check timing CT3, there is a banknote or the like that enters the stacking device above the separator 31 and blocks the detection device 34. In this case, the output of the detection device 34 and the amplifier 60 becomes a "0" signal, and the output of the NAND circuit 70 becomes "1".
The output of the AND circuit 69 becomes a "1" signal, the output of the OR circuit 68 also becomes a "1" signal, and the output of the abnormality check circuit 71 becomes "1".
This causes an abnormal signal to be emitted. That is, when there is a possibility that normal sorting of a predetermined number of sheets has not been performed, this check circuit 71 detects an abnormality.

As explained above, the present invention is designed to connect a beat device that knocks down paper sheets conveyed onto the entrance of a stacking device and a conveyance path, and a backup device that stacks a predetermined number of sheets knocked down by the beat device. A detection device is placed in each of the machines to count the number of paper sheets being conveyed, and when a predetermined number of sheets is reached, a separator is activated, so that a predetermined number of paper sheets can be automatically separated onto the backup. It has excellent effects such as being able to be integrated. In addition, 1 banknote
When stacking banknotes one by one, the operation of the gate beat device and the transport timing of the banknotes are checked, so if the beat operation is defective or the transfer is defective, it can be accurately detected, so that the stacking can be carried out without any malfunction in counting. . Furthermore, even when separating a predetermined number of banknotes, the timing of the separator operation and the timing of transporting the next banknote are checked, so that if the banknote separation operation is insufficient, it can be caught accurately. Because I became
This has a great effect on improving the counting accuracy of this type of machine, such as improving counting accuracy and making it possible to guarantee it. In this way, it is possible to reliably accumulate banknotes and separate a predetermined number of banknotes, and in case of failure, it can be reliably detected.
It is possible to reliably prevent occurrences such as excess or shortage of sheets, mixing due to overlap between bundles, and improper accumulation of bundles.
In this example, processing of banknotes has been demonstrated, but the present invention is not limited to this, and can be similarly implemented in a stacking device of a processing device that sorts paper sheets such as other banknotes.
In addition, the present invention is not limited to the embodiments described above, and it goes without saying that various modifications can be made without changing the gist of the present invention. Moreover, it goes without saying that the present invention can be applied not only to a beat device but also to a beat spring type accumulating device and an impeller type accumulating device.
