Description

[Detailed Description of the Invention] The object of the present invention is to provide a vending machine that does not require a reject control mechanism that accepts additional coins when a customer inserts them, regardless of the operating state of the vending machine. To provide a change dispensing method in which the remaining amount after subtracting the product sales amount from the input amount is used as change and when money is inserted during dispensing, the input money amount is also paid out as change along with the remaining amount.

First, an outline of an embodiment of the present invention will be explained with reference to the block diagram of FIG. When the inserted money detecting section B detects the insertion of money, the inserted money data is transmitted to the buffer device D including a counter, and the counter temporarily stores the amount or number of coins inserted. The input amount stored in the buffer device D and the amount stored in the storage device 1 are totaled by the calculation unit B, and the total amount is stored in the storage device 1 again. However, the timing at which the buffer device D transmits the input amount data to the calculation unit B' is controlled by the control unit C, rather than transmitting the input amount data to the calculation unit B' at any time. In other words, it is naturally impossible for the control section B to calculate the remaining amount by selling a product, subtract the change amount from the remaining amount during change disbursement, and add the input amount while the change is being calculated. Therefore, the control unit C sends the input amount data transmission prohibition signal to the buffer device D. Therefore, the control section C receives the sales signal from the product sales section F and the change payout confirmation signal from the payout confirmation device G, and determines whether or not the addition operation is possible. Further, the calculation result by the calculation unit B is sequentially determined by the determination unit, and a calculation result determination signal is input to the control unit C. The control section C determines the next operation of the vending machine based on the determination signal. For example, the input amount stored in the buffer device D and the storage device 1
When the remaining amount stored in the storage device 1 is summed up in the calculation section B and the result is determined as the judgment section date, the storage device 1 is judged to have overflowed.
The control unit C sends a command to the change dispensing device A to pay out the overflow amount of coins as change, and also sends a command to the control unit B to subtract the overflow amount of money and to the buffer device D to input the money. This sends a signal to prohibit transmission of amount data. When it is confirmed that the change dispensing device A is in the dispensing state, the dispensing confirmation device G sends a change dispensing confirmation signal. Next, the second part describes the operation in detail based on specific drawings.
The figure shows a specific circuit showing an inserted coin detection section E, a buffer device D, a judgment section, a storage device 1, and a calculation section B. The storage device MCCI stores the total input amount or the remaining amount after subtracting the sales amount after the sales operation, and 2 is a change calculation counter BCC.
It is. The device of the present invention is T.・T20T3・T4・T51
MCCI and BCC2 are controlled by timing pulses that are repeatedly generated in sequence from t・T7, and are equipped with a 7-stage delay flip-flop circuit that outputs one timing pulse with a one-bit delay. This is a shift register that performs shifting. In addition, 3, 4 and 5 of the inserted coin detection section E are 10 yen, 50 yen and 10 yen, respectively.
The coin switches 3, 4, and 5 are connected to buffer counters 6, 7, and 8 of the buffer device D corresponding to the type of coin. Each of the buffer counters 6, 7, and 8 is a counter that stores the number of coins inserted. When q coins of 1 are inserted, the buffer counter 6 sends an L signal to the AND circuit 9, and the buffer counter 7 sends an L signal to the AND circuit 9.
When a 0 yen coin is inserted, the buffer counter 8 transmits an upper signal to the AND circuit 10, and when a 100 yen coin is inserted, the buffer counter 8 transmits a signal to the AND circuit 11, respectively. The output of the buffer counter 8 is sent to the gates of AND circuits 9 and 10 via an inverter 12, and the output of the buffer counter 7 is sent to the gates of AND circuits 9 and 10 via an inverter 12.
3 to the gate of the AND circuit 9, if there are two or more signals on i, i2, the signal of the higher coin is inputted to the OR circuit 14 with priority. Therefore, the buffer device D is a circuit that stores the number of coins inserted and outputs information on coins inserted in the order of high-value coins. 15 is the above BCC
A full adder that together with 2 constitutes the arithmetic unit B has an MCC for An.
The count contents of I or BCC2 are input and Bn is OR.
The output of the circuit 14 and the operation signals of 10BCC, 10MCC, and 11 are input.

In the full adder 15, the contents of An and Bn are added, and the counted contents are written to MCCI or BCC2 from the S end. Furthermore, when there is a carry as a result of addition, a carry signal C is inputted from the Cout terminal via the AND circuit 19 and the flip-flop circuit 20 with a 1-bit delay, and the other gate of the AND circuit 19 is T7 timing pulse is inverter 2! Since the C signal is input through the Cin terminal, the C signal is not input to the Cin terminal at timing T7. The C signal is also output to the AND circuit 16 together with the T7 timing pulse, and when the AND circuit 16 obtains the logical product, the T7·C signal is output to the AND circuits 17 and 31. The control unit C of this embodiment is characterized by performing sequence control, in which each sequence is transitioned from timing T to timing T7 as one sequence, and predetermined operations and calculations are performed in each sequence. It accomplishes the purpose of the invention.

Figure 3 shows the control unit C, which is a sequence flip-flop circuit F, , F2, F3, F connected in a closed loop.
4, F5, F6, F7 and F8 and change payout coin determination stage 2
Same as circuit 9, sequence flip-flop circuit FA
, Fo, and when set, each sequence flip-flop circuit receives a sequence control signal S. ,S2,S
3, S4, S5, S6, S7, S8, SA, and So, respectively, to instruct each section to perform calculations and operations corresponding to each sequence. The flip-flop circuits F to F8 are connected in a closed loop as shown in FIG. 4, and their operations will be explained using the n-th and (n11)-th flip-flop circuits 41 and 42. The output of the previous flip-flop circuit is connected to the set terminal S of each flip-flop circuit together with the timing pulse T and the timing pulse via an AND circuit, and the reset terminal R is inputted with the timing pulse T and the timing pulse. Therefore, in the n-sequence, the flip-flop circuit 41 is in operation, and the output Sn is outputted from the control section C as an Sn sequence signal, and predetermined operations and calculations of the n-sequence are performed. On the other hand, since Sn is input to the AND circuit 43 together with T and the timing pulse, T
, when a timing pulse is generated, the flip-flop circuit 42 operates to form an (n+1) sequence and output Sn.
is output as an Sn sequence control signal, while being input to the set end of the flip-flop circuit at the next stage. Also, since the flip-flop circuit 41 is reset by this T timing pulse, Sn disappears. It should be noted that each flip-flop circuit 41, 42 is a set priority circuit,
In this case, when the flip-flop circuit 42 is set, it is set even if the timing pulse T is applied to its reset terminal. Also, the AND circuit 44 has T,
A prohibition signal is inputted together with the timing pulse via the inverter 45, but if a prohibition signal is generated, the AND
In the circuit 44, the logical product cannot be obtained, so the timing pulse T is not input to each flip-flop circuit 41, 42, and for example, the flip-flop circuit 42 is set (n
(11) When in the sequence T, it is not reset even at the timing point and remains in the (n11) sequence. It was mentioned above that the T7-C signal is generated in the AND circuit 16 of the determination section, but the T7-C signal is generated in the AND circuit 16 of the judgment section.
When the logical AND is obtained with the S2 sequence control signal in step 7, the overflow determination flip-flop circuit 18 is set and an overflow determination is performed, and an overflow signal OVF is sent from the determination section to the control section C.

Further, when the AND circuit 31 performs a logical product between the T7.C signal and the S5 sequence control signal, a determination is made to proceed to the sales standby sequence So, and a So set signal is sent to the control section C from the determination section. In the circuit in Figure 2, the numbers in the round frames are the control gate circuits included in the control section C, whose opening and closing are controlled by the respective sequence control signals.
Depending on the sent sequence control signal, the control gates necessary to perform the predetermined arithmetic operation of the sequence are opened. FIG. 5 is a diagram showing gates that open corresponding to each sequence, and the circles indicate the open state. Furthermore, S4
In the sequence, when the S4 sequence control signal and the OVF signal are input to the AND circuit 33, and when the S4 sequence control signal and the OVF signal indicating that there is no overflow are A
There are two cases in which the signal is input to the ND circuit 32. M.C.C.I.
The control gates (1) and (2) in the front stage of the BCC 2 and the control gates (2) and (2) in the return path from the rear stage to the front stage are opposite to each other, and when one is connected, the other is closed. ■and■
When is open, it is writing to MCCI and BCC2, so ① and ② are closed to erase the contents that have been stored so far, and the contents are deleted without being returned. MCCI and BCC2 to retain the memory contents when ■ and ■ are closed.
The contents of the subsequent stage are fed back and held through (1) and (2) every shift. Now, after inserting a coin, a product with a value less than the amount of coins inserted is selected and the product is served, and the selling price is subtracted from the amount inserted and the remaining amount is stored in the MCCI.In the S^ sequence, the next coin of 100 yen is inserted. Assume that the flip-flop circuit F operates from the S^ sequence and shifts to the S sequence.

At this time, in the S sequence, the upper signal is output from the buffer counter 8 to the AND circuit 11, while the AND circuit
S, a sequence control signal, and the output of the OR circuit 23 are input to the other gate of the circuit 11. Since the L and T4 timing pulses are input to the OR circuit 23, S,
As mentioned above, the sequence period is from T to T7 timing, so every time T2 timing and L timing are output from the OR circuit 23 to the AND circuit 11, the AND circuit 1
1 is T, the period from T7 timing 011.011.0
- Output a binary code signal of 0.0 to Bn of the full adder 15 via the OR circuit 14. This signal is input to BCC2 from the S terminal via control gate ■0, 0, 0, 1,
Writing is performed as 0, 1, and 0. On the other hand, AND circuit 1 1
is also connected to the coin buffer section 8, and the above-mentioned 0.11
When the output of 0, 1, 0, 000 is input, the coin buffer section 8 subtracts 1 from the input memory number and stores 1 100 yen coin.
The memory of inserting a card is erased. In the S2 sequence, the next input amount of 100 yen written in the BCC2 in the S sequence is added to the remaining amount stored in the MCCI.

Here, S^ and S assume that the remaining amount is 200 yen, and in the sequence, MCCI, which is a 7-stage shift register, is T.
, in the timing, each stage from R to R7 is set to 0, 0,
Memorize the remaining amount as 1.0.1.0.0, and do the following:
L・T4・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・ Carry is carried out as the timing progresses, but the contents of R7 are returned to R via control gate ■, and the remaining amount of 200 yen is transferred to the 17th It is stored and held at each timing as shown in the truth table shown in the figure.
In the S2 sequence, the contents of R7 at each timing are from T to 0, 0, 1, 0, in the T7 timing period.
1.0.0 and is output to An of the full adder 15. Also S
2 sequence, the control gate ■ opens and the contents of BCC2 change from T to 001, 0, 1, 0, in the T7 timing period.
0.0 and Bn' are output. Therefore, the input contents of An and Bn are summed by the full adder 15, and the result is 0.111.1.1.0 from the S end in the T7 timing period from T.
・Output as 0 and send to MCCI via control gate ■0.0
11.1.1.1.0 is written, and this arithmetic operation is shown in the truth table of FIG. As can be seen from the table, in this case, the carry signal is not generated from Cout, so it is a logical product of T7 timing pulse and T? - The C signal is not generated and the overflow judgment flip-flop circuit 18 does not operate. Note that R7 is the 0, 0, 1, 0, 1, 0, 0 that is output to An during the T7 timing period from T, because the control gate ■ is closed, so it is not fed back to R, and therefore the sum result is are sequentially written to the MCCI at each timing. In the S3 sequence, the sequence flow is divided into two ways.

First, to explain the operation of the pulse switch 40 that confirms that the change dispensing device has operated, the shaft 25 of the change dispensing motor
A cam 26 and a metal piece 27 as shown in FIGS. 6 and 7 are attached to the motor. In FIG. 6, the motor is stopped and the pulse switch output (PSW) is 1. After approximately 200 seconds have elapsed since the motor started rotating for change dispensing, the metal piece 27 separates from the proximity switch head 28 as shown in FIG. 7, and the PSW becomes 0. In the S3 sequence, when PSW=0, the sequence moves to S, which will be detailed later. However, in this case, since the motor is not rotating, PSW=1 and the process moves to the S4 sequence. Note that the setting of 200 ms will become clear later. S4
BCC when there is no overflow in the sequence
2, the contents of the MCCI are written.

In the S2 sequence, MCCI has 0.011.1.1.
When 1.0 is written and the control gates ■, ■, ■ are opened, the above-mentioned 0, 0, 1, 1, 1, 100 is input to the far end of the full adder 15 in the timing period from T to T7. The signal is output from the S end and written to BCC2. Also S
0, 1, and BCC2 of BCC2 stored before the 4 sequence.
The contents of 0, 1, 0, 0, 0 are R when the control gate ■ is closed.
Since there is no return from 7 to R, the contents of MCCI are BCC.
It is written in 2. Note that since the control gate (2) of MCCI is open, the output of the R7 stage is fed back to the R stage, so its contents are not erased. BC in S5 sequence
It is determined whether BCC2 is 0 or not based on the contents written in C2. In other words, in this sequence, the control gate ■
, ■ is opened and the memory contents of BCC2 are 0, 0, 1, 1, 1.
-110 is input to An of the full adder 15 via the inverter 30 as BCC1.110.010.0.1. On the other hand, the 11 calculation signal is inputted to Bn through the control gate 2, and therefore calculations are performed as shown in the truth table of FIG. When BCC=0, as can be seen from the truth table in Figure 14, the C signal is generated from the Cout terminal, and the AND circuit 16
Therefore, the logical AND with T7 timing pulse is obtained and T7
- Since the C signal is output from the circuit 16 to the AND circuit 31, and the S5 sequence signal is input to one gate of the circuit 31, the So set signal instructing the transition to the So sequence is output, and the sequence is Move to So. In other words, when BCC=0, BCC2 has written the contents of MCCI in the previous S4 sequence, that is, the total of the remaining amount and the next input amount stored in the coin buffer sections 6, 7, and 8, but BCC= If it is 0, the remaining amount is 0 and no additional coins have been inserted, meaning that no coins have been inserted into the vending machine, and the process moves to the So sequence. In this case, since 300 yen is stored in the BCC 2, the So set signal is not generated and the sequence moves to the change payout coin determination stage 29. In this S5 sequence, control gates (2) and (2) are closed, and the result of addition by the full adder 15 is not written to MCCI and BCC2. The change payout coin determination stage 29 is a part that determines how to pay out the 300 yen stored in the BCC 2 as change based on the operation of the calculation unit B and the control unit C. When paying out in 100 yen coins, the change is determined at 10. A signal and a drive command signal for the change dispensing mode are output, and the BCC2 has a control gate ■
The 110 operation signal, ie, T, is inputted to the 0, 1, 011, 0, 0, 0 input characters Bn in a timing period of T7 through the control gate (2) and written to the BCC2 through the control gate (2).

In addition, when paying out 50 yen or 10 yen, the control gate ■ or <0 is opened, and the 15th calculation signal and the 11th calculation signal are input to Bn, respectively, in the timing period from T to T7. 1.0.1.0.0.0.0, 1.0.0.0
・Written as 0, 0, 0. A time signal for driving the change dispensing motor in response to a drive command signal is output from the control unit C. However, when dispensing change with the motor as in this embodiment, it is difficult to determine whether the motor has completely entered the drive for dispensing change. If the machine is still running at least 200 seconds after starting, it is confirmed that change is being dispensed. Therefore, the control unit C must output the HG signal to 10 during this period of 200 seconds.
The time of 200 s is taken by the pulse switch 40 mentioned above.

The purpose of S6 and the next S7 sequence is to calculate the difference between the memory contents of MCCI and BCC2 using the full adder 15. At this time, as explained above, 300 yen is stored in MCCI as 0, 0, 1,
1.111.0 and BCC2 have 100 yen as 0.0.0.
It is held as 1, 0, 1, 0.

Therefore, in the S6 sequence, BCC is
The memory contents of 2 are 001 and 001 in the timing period from T to T7.
0.1.010.0 is output to the inverter 30, inverted, and sent to the An of the full adder 15 via the control gate ■.
011, 0, 1, 111, and the contents of MCCI are outputted to Bn as 011, 1, 1, 1, 0, 0 in the timing period from T to T7 through the control gate ■, and the 10th
Operations are performed as shown in the truth table in the figure, and the results are written from the S end to the MCCI via the control gate (2) in the T to L timing period. Furthermore, if the control gate ■ is open, the content written to the MCCI until now is 0 because the control gate ■ is closed.
・1・111・1・0・0 is T of the above writing, to T7
During the timing period, the output from R7 is not fed back and its contents disappear. Next, in the S7 sequence, the contents of MCCI written in the S6 sequence are transferred from T to A of the full adder 15 in the T7 timing period via control gates ■ and ■.
n, and Bn receives 11 calculation signals from the control gate (1), i.e., 1, 0, 0, 0, in the T7 timing period from T,
0, 0, and 0 are output, an operation is performed as shown in the truth table of FIG. 11, and the result of this operation is written to MCCI from the S terminal via control gate (2). In other words, the MCCI remembers that the remaining amount after dispensing the 100 yen coin is 200 yen. In the S8 sequence, the control gate ■ is opened to return BCC2 to zero, and BCC2 changes to 0, 0, 0 during the timing period from T to T7 of this sequence.
-Writes 0, 0, 0, 0 and returns to zero.

In addition, although the change dispensing mode is activated from the change dispensing coin determination stage 29, the PSW is still 1, and it takes approximately 20 minutes for the control unit C to confirm that the change dispensing operation has started.
The flow of the sequence is stopped at S8 by the above-mentioned prohibition signal until PSW=0 after s has elapsed. Therefore S6
, S7, and S8 sequences, the control section C outputs the HG signal and the drive command signal to 10. The change payout flow from sequence S to S8 has been described in detail above, but in the other sequences and the change payout coin determination stage 29, the calculation unit B calculates the change amount and While the remaining change is being calculated and the S8 sequence is stopped, the control unit C is outputting the HG signal and drive command signal to 10, so it is impossible to add coins.

When PSW=0 and the prohibition signal is released to return to the S sequence, if a coin is inserted between the S2 and S8 sequences in the same manner as described above, it is written to BCC2, and then S2 The sequence also adds to the MCCI. If the change dispensing motor is still running after overflow determination and PSW=0, the sequence is S,, S2
, S3 are repeated. If a coin is inserted during this time, of course write to 8CC2 with S and MC with S2.
Overflow is determined in writing to CI S3. Eventually, the change will be dispensed and the change dispensing motor will stop and P
When SW=1, the sequence moves to S4, and the second 100 yen coin is then dispensed in the same sequence as described above. Change is then paid out by repeating the same operation, and in the S7 sequence, the MCCI is calculated as 0, and in the S8 sequence, BCC2 is returned to zero as described above, and if there is no coin inserted in the S sequence, the MCCI is
CI becomes 0 and BCC2 also becomes 0. Therefore, when the last payout is completed and PSW=1 and the sequence shifts to S4, since BCC=0, the sequence shifts to the So sequence. Next, a case will be explained in which an overflow occurs due to the next input coin.

At this time, it is assumed that the remaining amount in MCCI is 1180 yen and 100 yen has been input. MCCI is S^ and S, in the sequence T, in the timing period from T7, each stage from R to R7 performs a carry like the truth table in Figure 18 and stores the remaining amount q of 118. keeping. On the other hand, in S, sequence, the input amount is written to BCC2 from 100 yen, and T,
In timing, each stage is 0, 0, 0, 1, 0, 1, 0.
It is maintained in the state of . In the S2 sequence, An' of the full adder 15 is T from the R7 stage of the MCCI, and T from the R7 stage of the MCCI.
011, 1, 0, 1, 1, 1 are input in 7 timing periods, and Bn' is T from the R7 stage of BCC2, and T? from the R7 stage of BCC2. During the timing period, 0, 1, 0, 1, 0, OQO is input, the calculation is performed as shown in the truth table in Figure 9, the result is output from the S terminal, and 0, 01010, 0, 0, MCCI is output. 0
is written and the carry signal C is T2, L, T4, T5, T
6. Output from Co mountain at timing T7. Also T7
At the timing, T7 and C are ANDed by the AND circuit 16 and the T70C signal is output to the AND circuit 7, but in this circuit 17, the AND is done with the sequence signal S2 and T7・C
The signal is input to the S terminal of the overflow judgment flip-flop circuit 18, which is set and outputs the OVF signal from the Q terminal. When the OVF signal is generated, the operations in the S3 and S4 sequences are not performed, and the BCC 2 shifts to the S5 sequence with the contents written in the S sequence unchanged. After that, if no coins are inserted, BCC
2, 100 yen is stored, so the process moves to the change payout coin determination stage 29. At the change payout coin determination stage 29, the change payout motor is started by performing the same operation as described above so as to pay out the overflow input amount of 100 yen as change.
Then, in the S6 sequence, the contents of MCCI are inputted to Bn of the full adder 15 via control gate 2 as 01010/0101010 in the T7 timing period, and 1/0 to An via control gates 2 and 3.・1・0・1
・Since 1.1 is input, the calculation is performed as shown in the truth table in FIG. 15, and the result is written to MCCI from the S end. And in the S7 sequence, the contents of this MCCI and the control gate■
110, 0, 0, 0, 0, 0 is calculated as shown in the truth table in Figure 16 in the T7 timing period from the 11 calculation signal, that is, T, through the S terminal, and the result is written to MCCI from the S end. The message is that there is a balance of 1,180 yen. Further, in the previous S2 sequence, the overflow judgment flip-flop circuit 18 is set, but in the S6 sequence, this sequence signal S6 is input to the R terminal of the flip-flop circuit 18, so it is reset in the S6 sequence. In the S8 sequence, after stopping for 200 seconds until BCC2 returns to zero and PSW=0, the process moves to the S sequence. S, sequence is 11 for MCCI
80 yen is stored and the overflowed input amount of 100 yen is being paid out, but as mentioned above, S2
If there is a next coin inserted between S8 sequence and S8 sequence, it will be written to BCC2, and furthermore, it will be written to MCC in S2 sequence.
After the overflow is determined in the S3 sequence, the change dispensing motor is rotating, that is, PSW=
If it is 0 and there is no overflow (OVF), the sequence returns to S, and continues going through S2-S3 as described above until PSW=1. If an overflow occurs due to the coins inserted during this period, the sequence stops at S3, the overflowing coins are stored in the coin buffer section, and when PSW=1, the sequence returns to S3.
Move to 4. Thereafter, in the same manner as described above, each sequence is repeated until the MCC turtle and BCC2 become 0, change is paid out, and the process moves to the So sequence. In this embodiment, input coin data to the storage device MCCI is performed via the buffer device D in any case, but if the calculation unit B is capable of adding the input amount at the time of inputting coins, the data is input to the buffer device D. When the amount or number of coins inserted is memorized and the addition operation becomes possible, the input coin data is input to the calculation unit B via the control unit C. Also, if the calculation unit B is capable of adding the input amount at the time of coin insertion. Alternatively, a circuit in which inserted money data is directly inputted to the storage device 1 from the inserted money detection section E can also be considered.

Conventional vending machines have been equipped with a reject control mechanism to prevent the problem of not being able to accurately memorize the amount of coins and collecting coins when coins are inserted while dispensing change.

However, as described in detail above, the present invention provides a buffer device D before the counting device 1, and uses the remaining amount after subtracting the sales amount from the input amount as change during the payout calculation operation.In this embodiment, from S2 The coins inserted during the S8 sequence are temporarily stored in the buffer device D, and when the calculation is completed, the inserted coins are added to the counting device 1, and the inserted coins are paid out as change along with the unpaid portion of the remaining amount. ChiP
The coins inserted when SW=0 are sequentially added to the counting device 1 from the buffer device D and are paid out as change along with the remaining amount, so that a reject control mechanism is not required. Therefore, even if a customer accidentally inserts a coin during change dispensing, that is, during a dispensing calculation operation or a dispensing operation, the coin can be returned without a reject control mechanism. Note that the above-mentioned payout operation is in progress when the calculation unit B is performing calculation operations and the control unit C is performing a control operation of sending a drive command signal to the change dispensing device A.
