Description

[Detailed description of the invention] [Technical field to which the invention pertains]

This invention is a coin recognition device (also referred to as a coin knock) that uses a different method for automatic vending machines (also referred to as Ui machines).
The present invention relates to a device that can be controlled by switching. Note that in the description of each figure below, the same reference numerals indicate the same or corresponding parts.

[Prior art and its problems]

The operation method of foreign-made coin mechs is commonly (MA+MB)
The domestic version is different from the coin knock operation method. The operation of this (MA+MB) system (hereinafter simply referred to as the foreign system) will be explained below based on an example of a conventional coin knock control circuit shown in FIG. 4 and a time chart shown in FIG. In addition, the number of set prices for the foreign system Coin Mech 4 (4A) in FIG. 4 shows an example of 4 prices. First, when a coin is inserted into the CoinMech 4A, the CoinMech 4A stores the amount of money inserted. Next, when the product selection button P (one of PI, P2 -...-) is pressed, the corresponding selection relay SR (SR
I, 5R2-...) and the price signal line PL (
A current flows from phase PH2 of the AC power line to phase PH1 of the AC power line to the corresponding selected price detection photocoupler 5 (one of 51 to 54) in Coinmech 4A through one of PLI to PL4), and the Change is coin knock control circuit 8
(time A in Fig. 5). The coin mech control circuit 8 checks whether the memorized amount of inserted coins is greater than or equal to the preset amount corresponding to the price signal line PL to which the voltage from the phase PH2 is input. If the value is above, the corresponding price signal output relay PR (one of PRI-PH1) is turned on (time B in FIG. 5). Therefore, the a contact PRa of the price signal output relay PR outputs the corresponding price signal line PL.
When the voltage of the AC power supply phase PH1 is supplied to the selection relay SR, the selection relay SR self-holds through its a contact SRa, and as a result, the auxiliary relay XA is energized through the a contact SRa of the relay SR. As a result, the corresponding product delivery mechanism (not shown) starts the ONL product delivery operation. At the same time as the auxiliary relay XA turns ON, the voltage of the AC power supply phase PH1 that was being supplied to the CREM terminal #6 of the coin MEC 4A is cut off by its b contact XAb, and the coin MEC 4A is no longer accepted (time C in Fig. 5). Price signal output relay PR turns OFF after a certain period of time (fifth control point), but at this point auxiliary relay XA closes its a contact XAa.
The product is already self-retained via the self-propelled switch 10 of the product delivery motor, and the product delivery operation continues. Then, at the end of the product unloading operation, the self-propelled switch 10 is temporarily turned OFF.
After F, turn on again. At this OFF point, auxiliary relay XA is deenergized. When the product unloading operation is completed in this way, the unloading motor self-propelled switch 10 and the b contact XAb of the auxiliary relay XA
CREM terminal of Coinmech 4A via #
The voltage of the AC power supply phase PH1 is applied to the terminal 6, and the machine enters the state of waiting for coin insertion again (time E in Fig. 5). The above is the coin knocking operation of the foreign method, that is, the (MA+MB) method. By the way, Figure 4 shows an example where the circuit for controlling sales is all constructed with relays, and the coin knock 4AIJ<
In order to determine the selected price, it was possible to drop the price signal line PL to the AC power supply phase PH2 through the contacts of the product selection button P. However, recent sales control circuits are mainly electronic circuits using microcomputers, and in such electronic circuits, the status of the product selection button is read at high speed on a time-sharing basis in a DC circuit that is isolated from the AC circuit. It is normal that the On the other hand, for the domestic coin knock, as described below, to determine the selected price, the AC power supply ■phase PH1 to ■phase PH2
The sales control circuit using an electronic circuit combined with this is configured so that the circuit for determining the selected price does not go through the product selection button P. For this reason, in a vending control circuit constructed entirely of relays, the circuit used for domestic coin knocks could be applied almost unchanged to foreign-made coin knocks, but with electronic vending control circuits, it could be applied to domestic coin knocks. There was a problem in that the method used could not be used as is for foreign-made coin knocks.

[Purpose of the invention]

The object of the present invention is to eliminate the above-mentioned drawbacks and provide an electronic coin knock control circuit that can be used in combination with both domestic coin knocks and foreign coin knocks.

[Key points of the invention]

The main point of this invention is that in controlling the CoinMech for domestic use, a relay that sends back the AC power phase voltage to the price signal line used to convey to the CoinMech the set price to which the selected product belongs. In controlling foreign-made coin knocks, the relay is switched to send back the AC power phase voltage to the price signal line, and a switch is provided to set the type of coin knock to be used. The main point is that the control method can be switched depending on the timing. In other words, the gist of the present invention is to determine that the input amount exceeds the set price of the product to be sold, and to sell the product at that price via a price signal line provided for each set price. A signal indicating that the product is actually selected (hereinafter referred to as a sellable signal) is output to the external circuit, and the external circuit sends a signal via the price signal line indicating that the set price of the product actually selected corresponds to the set price corresponding to the price signal line. This is a currency validation device that inputs a signal indicating that the price is a selected price signal (hereinafter referred to as the selected price signal) and returns the corresponding change. 1
After inputting the voltage of the phase (■ phase, etc.) as the selected price signal, confirm that the input amount is equal to or higher than the set price corresponding to the price signal line, and then input the voltage of the power supply line to the price signal line. The first currency validation device (such as a foreign coin mech) that outputs the voltage of the second phase (such as the ■ phase) as the sellable signal, or the amount inserted exceeds the set price. After sequentially outputting the voltage of the second phase of the power supply line as the sellable signal to the price signal line, a Clem signal given from an external circuit is determined based on the product selection, and all of the sellable signals are cut off. , then a second method of inputting the voltage of the second phase of the power supply line as the selected price signal from the price signal line corresponding to the set price of the selected product;
In a control device for a currency validation device that is configured to be able to selectively control any of the currency validation devices (such as a domestic coin mech), the currency validation device to be controlled is the first currency validation device. Setting means for setting whether it is a second item or a second item (Coinmech neck setting switch, etc.)
and means (selected price relay, etc.) provided for each of the price signal lines to supply a common voltage as the selected price signal to the selected price signal line based on the product selection; and a first phase of the power source; The present invention further includes means (such as a power supply phase changeover switch) for selectively switching the voltage of the second phase in accordance with the setting of the setting means and outputting it as the common voltage.

The present invention will be described in detail below based on FIGS. 1 to 3. FIGS. 1(A) and 1(B) are circuit diagrams showing the main part configurations of different embodiments of the present invention, and FIG. 1(A) is a circuit for controlling the above-mentioned foreign system coinmech 4 (4A). , the same figure (B) shows the domestic system CoinMech 4 (4B

This is similar to the figure, and this case also shows an example in which the number of set prices is four. Reference numeral 16 denotes a sales control circuit composed of a microcomputer or the like, and P (P1 to Pn) denotes a product selection button for inputting a product selection signal to the circuit. 11 (11
1 to 114) are price signal detection photocouplers, and the coin knock 4 is connected via the price signal line PL (PLI to PL4).
This is for detecting and inputting a sales enable signal from A (that is, a signal indicating that the input amount is equal to or higher than the set price corresponding to the price signal line PL and that the sale at the set price is possible). 5P (SPI ~ 5P4) is a selection price relay, which transmits the selection price signal (
That is, it is for giving a signal indicating to which price signal line PL the set price of the product selected by the product selection button P (Pi to Pn) corresponds to the coin knock 4A. Reference numeral 13 is a power supply phase changeover switch that switches the AC power supply to phase PH1 and phase PH2 depending on whether CoinMech 4 is foreign type 4A or domestic type 4B, and outputs the price signal line PL. It is intended to be given to 14 is a coin knock type setting switch, which sets whether the coin knock is 4A or 4B, and the sales control circuit 1
6, and is provided to operate in a control mode depending on the type of coin mech. CR is CRBMR2-, which is used to inform the coin MEC 4 from the sales control circuit 16 whether or not coins can be accepted. Each contact (a contact spa, b contact 5Pb) of the selected price relay SP connects each corresponding price signal line PL to AC via a power phase changeover switch 13 and a pull-down resistor 17.
It is connected to the power supply ■ phase PH2. For this reason, the selector switch 13 is short-circuited between P and R as shown in the figure. Further, the coin mech type setting switch 14 is also short-circuited between PR and P, and is input to the sales control circuit 16. Here, the changeover switch 13 and the coin mech type setting switch 14 are not limited to normal changeover switches.
It may also be a jumper wire on a printed circuit board. The sales enable signal output from the coinmech 4A is sent to the sales control circuit 1 via a price signal detection photocoupler 11.
6. Also, the a contact C of CREMR8-15
Ra is connected to supply the voltage of the AC power supply phase PH1 to the CREM terminal #6 of the coinmech 4A. FIG. 2 shows a block diagram of the sales control circuit 16 mentioned above. The states of the product selection button P, the price signal detection photocoupler 11, and the coin mech type setting switch 14 are read into the CPU 22 via an input/output ink face circuit (also abbreviated as Ilo) 21. Also, the CPU 22 is l10
21 to drive the selection price relay SP and CREM relay CR. The program is stored in ROM23,
The data are sequentially read into the CPU 22. Further, data for temporary storage is stored in the RAM 24 by the CPU 22. FIG. 3(A) shows the CPU 22 in the circuit of FIG. 1(A).

The M relay CR is turned OFF to prohibit coin acceptance by the coin mech 4A, and then the process proceeds to step S17, where the product delivery mechanism (not shown) is driven to carry out the product delivery operation, and then the process returns to step S12. By performing the above-described operations, coin knocking can be controlled using a time chart similar to that shown in FIG. Next, FIG. 1(B) shows a case where a domestic Coin Mech 4 (4B) is used in the circuit of FIG. 1(A). This coinmech 4B is configured to receive a selected price signal from the outside via the price signal line PL as a voltage from the AC power supply phase PH1, and also receives the CREM signal (CREM terminal #terminal section 6 signal) using a foreign system. I accept it using the opposite logic. That is, when the voltage of AC power supply phase PH1 is applied to terminal #6, coin acceptance is prohibited, and when this voltage is not applied, coin insertion is accepted. In this case as well, an example is shown in which the number of set prices for CoinMech 4B is 4. Here, the external circuit of the coin knock is set to P-
There is a switch from the R short circuit state to the P-Q short circuit state, but other than that, the hardware is completely the same as in Figure 1 (A).
It is the same as the circuit of As a result, in Fig. 1 (A), the voltage of the power supply phase PH2 is applied to the coin knock 4 as the selected price signal.

The operating procedure is as shown in FIG. 3(B). That is, as described above, in step S11 of FIG. 3(8), the setting of the coin MEC neck setting switch 14 is determined to be a domestic coin MEC (branch N), and then the process moves to the procedure of FIG. 3(B). Each time the input amount exceeds the set price, the coin knock 4B turns on the corresponding price signal output relay PR (PR1 to PR4) and outputs the corresponding price signal line PL (PLI to PL4).
) sends a sellable signal (voltage of AC power supply ■ phase PH1). First, in step S21, it is determined whether the price signal detection photo coupler 11 (111 to 114) is ON in order to detect the sellable signal from the coin MEC 4B (branch Y). Next, select the product in step S22! UP(PI~P
n) is ON, and determines that the price signal detection photocoupler 11 corresponding to the set price of the pressed selection button P is ON (that is, that a coin of the set price has been inserted). Confirm (branch Y), and turn on the corresponding selected price relay 5P (one of SPI to SP4) in step S23. Then, in step 324, CREM relay CR is turned on,
The CREM signal (voltage of the AC power supply ■ phase PH1) is applied to the CREM terminal # terminal portion 6 of the coin MEC through the a contact CRa to prohibit the acceptance of coins, and the selected product is carried out in step S25. On the other hand, upon input of the CREM signal, the coinmech 4B de-energizes all price signal output relays PR, and de-energizes the ON selection/price detection photocouplers 5 (51 to 5).

【Effect of the invention】

As is clear from the above explanation, according to the present invention, in an electronic control circuit that can switch and control coin mechs of any of nine foreign coin mechs and nine domestic coin mechs, a price signal is sent depending on whether the coin mech used is a foreign coin mech or a domestic coin mech. A means is provided for switching whether the selected price signal to be given to the coin knock via the line is taken from the phase side or the phase side of the AC power source, and a setting input is provided to convey the type of coin knock to be used to the control circuit. Since the means is provided, the same coin knock control circuit can be used for both domestic coin knocks and foreign coin mechs, resulting in the effect of realizing a flexible coin knock control circuit.
