Description

DETAILED DESCRIPTION OF THE INVENTION <Technical Field> The present invention relates to a raw material discharge control device for a vending machine.

<Prior art> A vending machine that takes beverage ingredients such as powdered coffee, sugar, and milk stored in separate raw material containers and dilutes and mixes them with hot water, etc. to the appropriate amount each time they are sold, and makes the prescribed drinking water available for sale. It is necessary to carry out a carry-out test of the beverage raw materials at certain times and check the quantity carried out, but in conventional systems, it is necessary to perform such a carry-out test by operating the select button on the open front door one by one.

That is, the conventional raw material discharge control device is shown in Fig. 2, in which 4 indicates a product selection switch corresponding to a group of product selection buttons provided on the operation panel in front of the door of the vending machine. The product selection switches 4a to 4n are grouped together, and for example, the product selection switch 4a is for coffee with cream and sugar, the switch 4b is for coffee with sugar, the switch 4c is for coffee with cream, and the switch 4d is for black coffee. Switch 4n is a product selection switch for cocoa.

5 is an input latch circuit, and AND gate G ₁
The signal obtained from the product select switch group 4 is latched by the latch pulse obtained from the latching pulse, and the latched data is sent to the input processing circuit 9 at the next stage.

The above AND gate _G1 is a clock signal output from the oscillator OSC when a coin signal (input from terminal 6) or a test signal (input when test switch 7 is turned on) is input to one input terminal through OR ₂ . is configured to output as the above-mentioned latch pulse.

Reference numeral 8 denotes a flip-flop which sustains the single pulse test signal output when the test switch 7 is turned on.

The input processing circuit 9 outputs a raw material selection signal from an output terminal based on a signal given from the input latch circuit 5. For example, the output terminals 9a to 9c output raw materials for coffee, sugar, and cream. A selection signal is outputted from the output terminal 9n, and a raw material selection signal for discharging cocoa is outputted from the output terminal _9n , and a series of operation command signals are outputted from the output terminal 9n1.

Ta to Tn are raw material discharge amount setting timers with variable setting times. For example, Ta is for coffee raw materials, Tb
Tc is for cream, Tn is for cocoa, and when the raw material selection signal is given, a raw material discharge signal is output for a set time to drive a discharge motor (not shown). .

In addition, Tn ₁ is a series operation time setting timer that sets the time required for the vending machine to execute one vending mode, and the operation starts when the above series operation command signal is output, and the set time elapses. Then, a time-up signal is output to the reset signal output circuit 10.

When this reset signal output circuit 10 receives a time-up signal from the series operation time setting timer Tn ₁ , it outputs a reset signal accordingly to the input latch circuit 5, the flip-flop 8, and each of the setting timers Ta to Tn and Tn _1. This is to reset the .

OR circuit OR ₃ is output terminal 9a of input processing circuit 9
When it receives a raw material selection signal from 9n to 9n, it outputs the signal to give a signal to the hot water valve and the mixer drive timer.

When checking the amount of raw material to be carried out, the test switch 7 is turned on and the flip-flop 8 is set.
This set output is given to one input terminal of AND gate _G1 , which is _connected to the oscillator OSC.
The input latch circuit 5 outputs a latch pulse in synchronization with the input of the clock signal to enable the input latch circuit 5.

Next, the tester presses the product selection switch 4a to test, for example, coffee with cream and sugar.
When turned on, the input latch circuit 5 inputs and latches a signal indicating that only the input corresponding to this product selection switch 4a is "H" and the others are "L", and the latched "H, L, L" , . . .L" are applied to the input processing circuit 9.

This input processing circuit 9 recognizes from the signals "H, L, L, . . . L" given from the input latch circuit 5 that it is the cream sugar coffee sales mode, and outputs the output terminals 9a to 9c. It outputs raw material selection signals for coffee raw material, cream, and sugar, respectively, and also outputs a series of operation command signals from output terminal _9n1 .

Then, a part of each raw material selection signal mentioned above causes the OR ₃ to give a signal to the hot water valve and mixer driving timer to drive the hot water valve and mixer. Although these are not shown, they serve as diluent supply means.

On the other hand, each raw material selection signal is also given to the raw material discharge amount setting timers Ta, Tb, and Tc, and these timers output raw material discharge signals, respectively, and drive the corresponding discharge motors to extract the desired amount of coffee from each raw material container. Raw materials, cream and sugar will be carried out.

Further, the series operation command signal is given to the series operation time setting timer _Tn1 to drive the timer.

The coffee with cream sugar is cooked in the mixer in conjunction with the signal from OR ₃ and the operation of each timer Ta to Tc and Tn ₁ . Then, when the time set in the series operation time setting timer Tn ₁ has elapsed and the desired amount of coffee with cream and sugar is produced, at this timing, the time-up signal is output from the timer Tn ₁ to the reset signal output circuit 10.
The reset signal output circuit 10 outputs a reset signal to the input latch circuit 5, flip-flop 8, and each timer Ta to Tc.
Reset Tn ₁ and return to the original sales waiting state.

The above is the sales mode for coffee with cream sugar during normal sales, and the point is that when any switch in the product selection switch group 4 is turned on, the raw material selection signal and sequence necessary for the product corresponding to the switch are activated. An operation command signal is output from the input processing circuit, and in conjunction with the raw material selection signal, the corresponding raw material discharge amount setting timer, hot water valve, and mixer driving timer are driven to transport raw materials and hot water, mix them, and produce a predetermined amount. While drinking water, a series operation time setting timer is driven by a series operation command signal to control one sales operation time.

<Problems to be Solved> Therefore, when carrying out a test for carrying out raw materials, it is necessary to operate the product selection buttons provided on the operation panel on the front of the door one by one, as in the case of purchasing work. Moreover, since a diluent such as hot water is supplied together with the raw material, it is extremely troublesome to receive and take out the raw material alone.

<Means for solving the problem> This will be explained using FIG. 1 corresponding to the embodiment.
The same parts as those in FIG. 2 showing the conventional example are given the same reference numerals and the explanation will be omitted.

1 is installed on the vending machine body or the back side of the door, etc.
This is a test ingredient setting device for setting beverage ingredients to be tested for delivery. The setting device 1 may be a binary digital switch or a group of switches corresponding one-to-one to each beverage ingredient.

Reference numeral 9 denotes an input processing circuit that independently outputs a raw material selection signal for each type of beverage raw material to be delivered in response to the operation of the product selection switch, and similarly responds to the operation of the raw material setting device 1. .

Reference numeral 11 denotes a diluent selection means that receives a raw material selection signal from the input processing circuit 9 and generates a diluent selection signal that operates a hot water valve and a timer (diluent supply means [not shown]) for driving the mixer. . This diluent selection means is configured not to generate a diluent selection signal when it receives a detection signal from the detection means NOR ₂ which detects that a signal is output from the raw material setting device 1. The above detection means NOR ₂
For example, a Noah gate into which all signals from the raw material setting device 1 are introduced is used.

<Function> When the product selection switch 4 is operated while the test switch 7 is on, a raw material selection signal is output from the input processing circuit 9 and the corresponding raw material discharge amount setting timer is activated.
Ta to Ta are driven and the raw material is carried out from the raw material container.

At this time, since no signal is output from the raw material setting device 1, the detection means NOR ₂ does not output a detection signal. Therefore, the diluent selection means 11 receives the raw material selection signal from the input processing circuit 9, generates a diluent selection signal, drives the diluent supply means, and supplies the diluent.

Therefore, when operating the product selection switch 4,
The desired beverage is obtained.

On the other hand, when setting beverage ingredients using the test ingredient setting device 1, for example, when operating the setting device 1 with the door open, the ingredient setting selects the type of ingredient to be carried out from the input processing circuit 9. A signal is output and the corresponding raw material discharge amount setting timers Ta to Tn are driven. As the timers Ta to Tn are driven, the raw material is discharged from the raw material container.

At this time, of course, since the detection signal is output from the detection means NOR ₂ , the dilution liquid selection means 11 generates the dilution liquid selection signal even though the raw material selection signal is generated from the input processing circuit 9. do not.

Therefore, the diluent is not supplied and only the beverage raw material is discharged, so that the amount of the beverage raw material can be confirmed by receiving it in a cup, for example.

<Example> FIG. 1 is an electrical circuit diagram showing a raw material discharge control device according to the present invention, and the same parts as those in FIG. In the figure, 1 is a test material setting device installed inside the vending machine main body or inside the door, and 4 consists of four switches 2a to 2d.
It consists of a binary digital switch unit 2 and a binary decimal decoder 3.

The binary digital switch unit 2 outputs a 4-bit logic signal from the output terminal depending on the on/off state of the switches 2a to 2d, and outputs a binary signal.
The decimal decoder 3 receives the logical signals at input terminals A to D, converts them into decimal signals, and outputs the signals from output terminals numbered 0 to 9.

This test raw material setting device 1 is equipped with all switches 2 of the binary digital switch section 2 during normal sales.
A to 2d are turned off, all outputs are set to LOW (hereinafter referred to as "L"), and the binary decimal decoder 3
All output levels are set to "L".

5 is an input latch circuit, and AND gate G ₁
The signals obtained from the binary decimal decoder 3 or product select switch group 4 of the test material setting device 1, which are input to the input terminals 0 to 9 by the latch pulse obtained from the OR gate group (hereinafter referred to as
_OR1 ) and sends the latched data to the input processing circuit 9 at the next stage.

Reference numeral 11 denotes a diluent selection means for obtaining a diluent selection signal for operating a timer (diluent supply means) for driving a hot water valve and a mixer, and an AND gate Ga.
Each AND gate receives raw material selection signals from output terminals 9a to 9n of the input processing circuit 9 corresponding to one input terminal, and a NOR circuit (called NOR _{2 )} to the other input terminal. ), and when the output of this NOR ₂ and the outputs of the corresponding output terminals 9a to 9n are both "H", a diluent selection signal is given to the hot water valve and mixer driving timer through OR ₃ . ing.

The NOR ₂ is a detection means that outputs "H" when all outputs of the binary decimal decoder 3 are "L".

In this embodiment, there is another NOR circuit (NOR ₁ ) that receives outputs from the 1st and 2nd output terminals of the binary decimal decoder 3.
The output of NOR ₁ is set as the above raw material discharge amount setting timer Ta.
The raw material selection signal from the output terminal 9a of _the input processing circuit 9 is applied to the other input terminal of the AND gate _G2 .

The embodiment of the present invention is constructed as described above, and first, a normal sales operation will be explained.

In this case, each switch 2 of the test material setting device 1
Since a to 2d are all off, all outputs of the binary decimal decoder 3 are "L", and therefore,
The outputs of NOR ₁ and NOR ₂ are "H", and the inputs of AND gate G ₂ and one of the input terminals of Ga to Gn are all "H".

In this situation, if the purchaser inserts a predetermined coin into the coin slot (not shown),
Coupled with this, the coin signal obtained from terminal 6 is
The signal is applied to one input terminal of an AND gate _G1 via _OR2 , and the AND gate _G1 outputs a latch pulse in synchronization with the input of the clock signal of the oscillator OSC to enable the input latch circuit 5 to latch the input.

Next, when the purchaser turns on the product selection switch 4a to purchase, for example, coffee with cream or sugar, the input latch circuit 5 outputs only the input corresponding to this product selection switch 4a to "H" and the others to "L". A signal indicating a certain fact is input and latched, and the latched "H, L, L, . . . L" signal is supplied to the input processing circuit 9.

This input processing circuit 9 recognizes from the signals "H, L, L, . . . L" given from the input latch circuit 5 that it is the cream sugar coffee sales mode, and outputs the output terminals 9a to 9c. It outputs raw material selection signals for coffee raw material, cream, and sugar, respectively, and also outputs a series of operation command signals from output terminal _9n1 .

Then, the above raw material selection signal parts are both NOR ₂
A signal of "H" is applied to the other input terminal of the AND gates Ga to Gc, which have one input terminal, to turn on each AND gate and send a diluent selection signal to the hot water valve and mixer drive timer from _OR3 . to drive the hot water valve and mixer. the above
NOR ₂ and each AND gate Ga to Gc serve as a blocking means for blocking generation of the diluent selection signal.

On the other hand, each raw material selection signal is also given to the raw material discharge amount setting timers Ta, Tb, and Tc, and these timers output raw material discharge signals, respectively, and drive the corresponding discharge motors to extract the desired amount of coffee from each raw material container. Raw materials, cream and sugar will be carried out.

Further, the series operation command signal is given to the series operation time setting timer _Tn1 to drive the timer.

The coffee with cream and sugar is cooked in the mixer in conjunction with the signal from OR ₃ and the operation of each timer Ta to Tc and Tn _1. Therefore, the above series of operation time setting timer Tn ₁ is set. When the predetermined amount of time has elapsed and the coffee with cream and sugar has been prepared, a time-up signal is applied from the timer Tn ₁ to the reset signal output circuit 10 at this timing.
A reset signal is output from 0 to reset the input latch circuit 5, flip-flop 8, and each timer Ta to Tc and Tn ₁ , returning to the original sales waiting state.

The above is the sales mode of coffee with cream sugar during normal sales.

Now, next, we will explain the raw material delivery test.

Now, for example, if you want to carry out a sugar transport test, turn on the switch 2b of the test raw material setting device 1, output a signal of "H" from the first output terminal of the binary decimal decoder 3, and also At the same time, the test switch 7 is turned on, a test signal is applied from the flip-flop 8 to the AND gate _G1 via _RO2 , and a latch pulse is applied to the input latch circuit 5 in conjunction with the clock signal output from the oscillator OSC.

Then, the latch circuit 5 inputs and latches the "H" signal received through OR ₁₁ in OR ₁ as well as the overall "L, H, L, L, . . . L" signal, and outputs the input processing circuit. Supply to 9.

Based on the signal received from the input latch circuit 5, the input processing circuit 9 recognizes that the coffee is made with sugar, and outputs a raw material selection signal from its output terminals 9a and 9b, and a series of operation command signals from its terminal _9n1 . Strengthen.

However, at this time, the "H" output from the first terminal of the binary decimal decoder 3
Since the outputs of both NOR ₁ and NOR ₂ are "L" in the signal, both AND gate G ₂ and Ga, Gb cannot output "H", and therefore, the sugar discharge amount setting timer Tb The only operation is to drive the sugar removal motor and perform the sugar removal test.

Further, the series operation time setting timer Tn ₁ starts operating in response to the series operation command signal, and when a predetermined time elapses, it outputs a time-up signal and causes the reset signal output circuit 10 to output a reset signal. The flip-flop 8 and the material discharge amount setting timer Tb are each reset to return to the original standby state.

In addition, when carrying out a coffee raw material carry-out test, turn on the switch 2a of the test raw material setting device 1 and set the 0th terminal of the binary decimal decoder 3 to "H".
Then, the input latch circuit 5 latches the signal "L, L, H, . . . L", and the input processing circuit 9 is made to recognize that it is black coffee.

The input processing circuit 9 also has an output terminal 9a.
A raw material selection signal is outputted and applied to AND gate _G2 and Ga.

However, at this time, the NOR ₂ obtains an "H" signal from the 0th terminal of the binary decimal decoder 3, sets its output to "L", and turns off the AND gate Ga, so the hot water valve and The mixer drive timer is not activated, and only the coffee raw material discharge amount setting timer Ta is driven through the AND gate _G2 , which receives an "H" signal from NOR ₁ , and a coffee raw material discharge test is executed.

Then, when the series operation time setting timer Tn ₁ times up, it returns to the original standby state.

As described above, according to the present invention, the normal selling operation by inserting a coin and the raw material delivery test can be performed.Of course, the test switch 7 is turned on and a latch pulse is input to the input latch circuit 5. By operating the product selection switch group 4 at , test sales can be performed with the same effect as the normal sales operation described above.

<Effects> The present invention includes a test raw material setting device separate from the product selection switch, a detection means for detecting a signal generated when the test raw material setting device is operated, and a detection means for receiving the detection signal of this detection means. In this case, since a diluent selection means that does not generate a diluent selection signal is provided, by operating the test raw material setting device, it is possible to carry out a test for carrying out only the raw material without supplying the diluent. If the container is installed inside the vending machine body or on the back side of the door, it is possible to carry out the test with the door open.
