Description

[Detailed Description of the Invention] This invention relates to a bill sorting device that automatically distinguishes currency bills and sorts and stores them.

For example, in Japan, there are four types of banknotes: 10,000 yen, 5,000 yen, 1,000 yen, and 500 yen. In department stores, supermarkets, banks, etc. that handle large quantities of such banknotes in a day, these banknotes must be aggregated or classified so that they can be easily processed by the handling financial institutions.
Therefore, there has been a need for an automatic banknote handling device that can sort and tabulate a large amount of such currency banknotes. Recently, in response to demand from financial institutions that handle banknotes, machines that automatically classify and tabulate the four types of currency notes have been developed and are beginning to be used in the market. However, such an automatic banknote processing apparatus requires complicated and large-scale mechanisms and controls to realize complete automation, including the differences in size between currency banknotes. Therefore, this device is necessarily large and also expensive.

This idea was created in view of the above-mentioned circumstances, and aims to provide a bill sorting device that simplifies the banknote sorting mechanism and control, takes up less space, and is inexpensive. It is characterized by having a rotary guide plate and a partition plate to accurately partition the banknotes sorted by the guide plate.

An embodiment of this invention will be described below with reference to the drawings. Fig. 1 is a sectional view showing the configuration of the main parts of a banknote sorting device which is an embodiment of the present invention, Fig. 2 is a sectional view taken along the line shown in Fig. 1, and Fig. 3 is a sectional view taken along the line shown in Fig.
The figure shows the relationship between gears, microswitches, and motors that perform banknote sorting operations. In these figures, numeral 1 is the insertion slot for handling banknotes,
The banknote detection sensor 2 is provided at the entrance of the conveyor belt 3 at the back of the insertion slot 1, and serves to detect the presence or absence of inserted banknotes. The feed roller 5 is provided further inside the conveyor belt 3. That is, the conveyor belt 3
is located between the bill detection sensor 2 and the feed roller 5, and conveys the bill that has passed the bill detection sensor 2 to the feed roller 5 while passing through the discrimination section 4. The determining unit 4 is provided midway in the conveying direction of the conveying belt 3, and determines the type and authenticity of the banknotes being conveyed. The feed roller 5 feeds the banknotes conveyed by the conveyor belt 3 to the banknote sorting section 8 through the timing sensor 6 and the passage hole 7. The timing sensor 6 is a sensor that detects whether the taken banknotes have passed through the passage hole 7 and been correctly conveyed to the banknote sorting section 8. The banknote sorting section 8 is a part that sorts out the conveyed banknotes based on the discrimination result of the discrimination section 4, and includes four guide plates 9, 9, . . . necessary for sorting.

A is fixed coaxially to the gear 10, and has detection protrusions extending radially outward at four equal locations on the circumference. As a result, the rotation of the gear 10 causes the shaft 10 to
It is possible to detect the positions of the four guide plates 9, 9, . A partition plate 12 is attached to the bottom of the bill sorting section 8 at a position such that its plane includes the shaft 10a. This partition plate 12, in conjunction with the action of the guide plates 9, 9... plays the role of distributing X banknotes and Y banknotes into partition chambers 31, 32, respectively, which are partitioned by the partition plate, and the banknotes are distributed here. The banknotes are dropped into the banknote storage section 13 below the partitions 31 and 32 and stored therein. A gear 15 is attached to the shaft of a motor 14 that rotationally drives the shaft 10a.
This gear 15 is connected to the gear 1 via gear trains 16 and 17.

are attached coaxially, and the position detection sensor 19b of a microswitch, for example, is operated by these convex portions. As already mentioned, the position detection sensor 19a serves to detect the position of the guide plates 9, 9, . . . by engaging with the convex portion of the position detection plate 11a.

Next, FIG. 4 is a circuit configuration diagram in one implementation of this invention, in which reference numerals 20 are the position detection sensors 19a,
This is a two-input AND gate that outputs "1" when 19b becomes a binary signal "1", and this output (position signal) is the trigger input terminal of flip-flops (D-type flip-flops) 21 and 22. It is supplied to T. The flip-flop 21 is
This flip-flop is set at the first rise of the position signal (output signal of AND gate 20) when the output of flip-flop 29 is "1", and its output Q is supplied to one input terminal of OR gate 23. Flip flop 22 is or gate 23
This flip-flop is set at the rising edge of the position signal when the output of the flip-flop is "1", and its output Q is input to the stop terminal B of the motor drive circuit 24, the reset terminals R of the flip-flops 28 and 29, and the input of the delay circuit (DL) 25. Supplied to the terminal. The OR gate 23 has a flip-flop 2 at one input terminal.
The output Q of flip-flop 28 is supplied to the other input terminal. The motor drive section 24 drives the motor 14, and when "1" is supplied to its terminal F, the motor 14
is rotated in the FW direction, and when a "1" signal is supplied to terminal R, the motor 14 is rotated in the RV direction, and when a "1" signal is supplied to stop terminal B, the rotation of the motor 14 is stopped. This is a circuit that allows The delay circuit (DL) 25 is a circuit that generates a pulse whose output becomes "1" after a certain period of time has passed since the output Q of the flip-flop 22 becomes "1".
The flip-flops 21 and 22 are simultaneously reset when the output pulse of the delay circuit 25 becomes "1".
The AND gate 26 has the discriminator 4 at one input end.
It is a two-input AND gate in which a signal when the banknote determined by is an ing. In the AND gate 27, a signal when the banknote discriminated by the discriminator 4 is a Y yen bill is inputted to one input terminal, and a timing sensor 6 is input to the other input terminal.

is supplied to. The flip-flop 28 is an SR type flip-flop that is set when the output of the AND gate 26 is "1", and its output Q is supplied to the F terminal of the motor drive unit 24 so as to rotate the motor 14 in the FW direction. The flip-flop 29 is an SR type flip-flop which is set when the output of the AND gate 27 is "1", and its output Q is supplied to the R terminal of the motor drive unit 24 so as to rotate the motor 14 in the RV direction.

Next, the operation of the bill sorting device of this invention having the above configuration will be explained. First, when X yen banknotes are inserted into the insertion slot 1, the banknote detection sensor 2 transmits a signal indicating that there is an inserted banknote to a control unit (not shown), and this control unit outputs a command to convey the banknotes, and The bill is conveyed by the conveyor belt 3 to the feed roller 5 while the type of banknote is determined by the discriminator 4. Since the banknote that passed through the discriminating section 4 during this conveyance is an X yen bill, the output of the discriminating section 4 becomes an X yen signal, and this signal is input to one side of the AND gate 26. The banknotes conveyed to the feed roller 5 pass through the passage hole 7 and pass through the guide plates 9, 9, . . . of the banknote sorting section 8.
When the banknote is conveyed horizontally onto any one of the banknotes and completely passes through the passage hole 7, the timing sensor 6 outputs a signal "1" indicating the end of banknote conveyance.
The output of this timing sensor 6 is AND gate 2
As a result, the output of AND gate 26 becomes "1" and flip-flop 28 is set. The output of the flip-flop 28 causes the motor drive member 24 to operate to rotate the motor 14 in the FW direction. In this way, the motor 14 rotates in the FW direction, and the position detection sensors 19a and 19b are both set to "1" by the protrusions every 90 degrees on the position detection plates 11a and 11b.
The rotation continues until the position detection sensor 19a,
When both 19b become “1”, AND gate 20
The output of is "1". Since the output Q of the flip-flop 28 is supplied to one input of the OR gate 23, the output of the OR gate 23 becomes "1" and at the same time, the D terminal of the flip-flop 22 becomes "1".
When the output of the AND gate 20 rises, the flip-flop 22 is set, and the output Q of the flip-flop 22 is supplied to the stop terminal B of the motor drive section 24, so that the motor is set to FW.
Stops at a position rotated 90° in the direction. In this process, the X
When the axis 10a of the yen bill rotates 90 degrees in the FW direction, the bills placed on the guide plates 9, 9, etc. become vertical, and as shown in FIG. The banknotes fall into the partition room 31 and are then regularly stored in the banknote storage section 13 where X yen bills are stored. The flip-flop 28 is reset when the flip-flop 22 is set, and the flip-flop 22 is reset by the delay circuit 25 after a predetermined period of time has elapsed after the flip-flop 22 is set.

Next, when a Y yen bill is inserted into the insertion slot 1, the bill detection sensor 2 transmits a signal indicating that there is an inserted bill to a control unit (not shown), which outputs a command to transport the bill, and the Y yen bill is The bill is conveyed by the conveyor belt 3 to the feed roller 5 while the type of bill is determined by the discriminator 4 . Since the banknotes that passed through the discriminating section 4 during this conveyance are Y yen bills, the output of the discriminating section 4 becomes a Y yen signal, and this signal is input to one side of the AND gate 27 . The banknotes conveyed to the feed roller 5 are conveyed horizontally through the passage hole 7 onto any one of the guide plates 9, 9, . . . of the banknote sorting section 8,
When this banknote completely passes through the passage hole 7, the output of the timing sensor 6 becomes a signal "1" indicating the end of banknote conveyance.
Output. Since the output of the timing sensor 6 is supplied as the other input of the AND gate 27, the output of the AND gate 27 becomes "1" and the flip-flop 29 is set. The output of the flip-flop 29 causes the motor drive section 24 to operate to rotate the motor 14 in the RV direction. In this way, the motor 14
The position detection plates 11a and 11b rotate in the RV direction.
Position detection sensor 19a,
The rotation continues until both position sensors 19b become "1", and when both position sensors 19a and 19b become "1", the output of the AND gate 20 becomes "1". On the other hand, since the output Q "1" of the flip-flop 29 is supplied to the data terminal D of the flip-flop 21,
When the output of AND gate 20 rises, flip-flop 21 is set. At this time, or gate 2
Since the output of flip-flop 3 is “0”, flip-flop 2
2 is not set, B of the motor drive unit 24
The terminal is "0", so the motor does not stop at 90 degrees but rotates further in the RV direction. Due to the rotation of the motor, the position detection sensor 19 rotates at the next 90 degrees.
When the outputs of a and 19b both become "1", the output of the AND gate 20 also becomes "1". On the other hand, at this point, the output Q "1" of the flip-flop 21 is supplied to the other input of the OR gate 23, so
The data terminal D of the flip-flop 22 is set to "1". Therefore, when the output of the AND gate 20 rises, the flip-flop 22 is set.
By supplying the output Q of the flip-flop 22 to the stop terminal B of the motor drive section 24, the motor is stopped at a position rotated by 180 degrees in the RV direction. In this process, the axis 10a of the Y yen bill hanging horizontally on the guide plates 9, 9... is in the RV direction.
By rotating 180 degrees, the banknotes placed on the guide plates 9, 9, etc. become vertical, and as shown in FIG. The Yen bills are regularly stored in the storage section 13 at the place where the Y-yen bills are stored. The flip-flop is reset in the same way as when processing X yen bills.

In this way, according to the present invention, two types of banknotes are distinguished, and the guide plates 9, 9... are rotated, and the X yen banknote is rotated 90 degrees and falls to the X yen bank side around the partition plate 12, while the Y yen banknote is The two types of banknotes can be reliably sorted by a simple structure and control such that the yen banknote rotates 180 degrees and falls toward the Y yen banknote side centering on the partition plate 12.

It was considered that the amount of rotation of the guide plates 9, 9, etc. should be set to 180 degrees for both denominations in order to distribute the two types of banknotes, but the rotation of the guide plates was fast, so the banknotes were
When using yen bills, a problem arises in that they get caught between the guide plates 9, 9, . . . and the partition plate 12 before they fall. Further, the reason why two position detection sensors 19a and 19b are provided is to make positioning accurate, so one sensor may be used.

As explained above, according to this invention, the number of banknotes to be sorted is limited to two types, and the sorting operation is performed by rotating mutually orthogonal guide plates by 90 degrees or 180 degrees. The rotation control circuit can be assembled into an extremely simple and reliable circuit, and the overall mechanism and control circuit have the advantage of being sufficiently simple and inexpensive to configure, and of course, the accuracy and reliability of the distribution operation can also be improved. The effect is sufficiently high that it can be guaranteed.
