If an abnormality occurs in the dispensing device of the selected column, the user needs to give a refund instruction to the deposit processing unit 36 by manual operation, and in order to purchase another product, the user has to manually issue a refund instruction to the deposit processing unit 36. They are forced to insert coins into a vending machine.

In addition, as seen in Japanese Patent Application Laid-open No. 53-5698, in some cases, when the product payout is not completed within the timer time, the control section 38 controls the input money processing section 36.
There is a system that automatically refunds the coins that have been inserted.

Problems to be Solved by the Invention In this way, in the conventional configuration, the timer 46
Although it is possible to detect a dispensing error in the product dispensing device using
``re-inserting the refunded coins'' or ``re-inserting the refunded coins'' even for items that are automatically refunded, and reinserting coins is a hassle and there is a risk of losing the desire to purchase. However, sales are expected to decline.

SUMMARY OF THE INVENTION An object of the present invention is to provide a product dispensing abnormality detection device that allows a product to be paid out of another product without re-inserting coins even when a dispensing abnormality occurs.

Means for Solving the Problems The product delivery abnormality detection device of the present invention includes a sales price setting unit that outputs a bend signal to a selection pushbutton switch corresponding to a product whose sales price is within the input amount, and a sales price setting unit that outputs a bend signal to a selection pushbutton switch corresponding to a product whose sales price is within the input amount. a control unit that detects that any of the selected selection pushbutton switches has been operated, resets the output of the bend signal, and starts energizing the product dispensing device of the column corresponding to the operated selection pushbutton; a dispensing confirmation switch that detects the end of one operation of the product dispensing device; a specified time is set longer than the time of the one operation during normal operation; and a dispensing confirmation switch starts timing at the start of the energization or the start of the one operation; A timer whose timing is reset by the payout confirmation switch at the end of one operation is provided, and the control section includes:
The present invention is characterized in that the selection column at the timing when the timer detects a time-up is switched to a sold-out state, and the sales price setting unit is instructed to reset the bend signal.

Effect: According to this configuration, when an abnormality occurs, the timer detects the occurrence of the payout abnormality and the control section sets the selection column to the sold-out state. Therefore, the power supply to the power source is immediately turned off even though the product delivery has not been completed, thereby preventing the power source from overheating.

Furthermore, when an abnormality is detected, the control unit controls the sales price setting unit and resets the bend signal, so there is no need to perform the troublesome operations of ``refund operation'' and ``reinsertion of refunded coins'' as in the past. It is possible to purchase products in other columns.

Embodiment Hereinafter, an embodiment of the present invention will be described based on the drawings.

FIG. 1 shows a front view of a vending machine that can sell two types of products, A and B, with the same selling price. 1 is a product display window, 2 is a coin slot, 3A and 3B are product selection pushbutton switches for columns A and B, respectively, 4A and 4B are sold-out indicator lamps for columns A and B, respectively, and 5 is a product takeout port. .

FIG. 2 shows the electrical circuit of the device. Reference numeral 6 denotes an input amount counter, and 7 denotes a sales price setting unit. During normal sales operation, input amount information given from the input amount counter 6 is held until the end of product dispensing, and the input amount information being held and the A column are A bend signal 7A is outputted to the sellable selection pushbutton switch by comparing the sales price of column B and the selling price of column B. Reference numeral 8 denotes a control unit of each device, which controls the product dispensing device 9 according to the operated selection pushbutton switch, and also controls whether either selection pushbutton switch 3A or 3B receiving the bend signal 7A is operated. is detected and the output of the bend signal 7A is reset. The product dispensing device 9 has electric motors 10A and 10 for each column.
B, and the electric motor 10 is controlled by the control unit 8.
Relays 11A and 11B that control on/off of energization to A and 10B, sold-out detection switch 12A,
12B, and payout confirmation switches 13A and 13B that detect the end of one operation of paying out selected products.

FIG. 3 shows the structure of the product dispensing device 9. Since both A column and B column have the same structure,
Here, the stocker 14 in column A will be explained. Reference numeral 15 indicates the product; 16a, 16b, and 16c are holes formed in the bottom wall, the lower part of the front wall, and the lower part of the rear wall of the stocker 14 as passing holes for the pusher 17 for dispensing the product; 18 is the sold-out detection switch 1;
This is a hole for inserting the sensing lever 19 of 2A. Here, the pusher 17 is connected to the electric motor 11 via a rotation → linear reciprocating motion conversion mechanism (not shown) such as a mangle.
A, the sensor lever 20 of the payout confirmation switch 13A is configured to be movable to the virtual line position by the pusher 17 in the stopped state.
In normal sales operation, the control unit 8 starts energizing the electric motor 10A via the relay 11A based on the selection pushbutton switch 3A, and the product delivery confirmation switch 13A The energization is turned off when the return to the stop position is detected. 21
is a chute that guides the product 15 discharged from the stocker 14 by the pusher 17 to a point facing the outlet 5.

In FIG. 2, reference numeral 22 denotes an abnormality detection device having a timer, which is configured as shown in FIG. 4.
23 is a timer, and the payout confirmation switch 13
Timing is started at the timing when A or 13B detects the start of movement of the pusher 17 of each column, and the timing is reset when the payout confirmation switch 13A or 13B detects that the pusher 17 has returned to the stop position. The specified time T of the timer 23 is set to be longer than the time required for the payout confirmation switch 13A to detect the start of movement until the return detection in normal sales operations. 30 is an OR gate, 24A and 24B are AND gates that detect coincidence with the payout signals of the A column and B column, respectively, and 25A and 25B are R-S flip-flops that are set by the outputs of the AND gates 24A and 24B, respectively. When the timer 23 detects a time-up condition, the R-S flip-flop 25A corresponds to the selected column at that time.
Alternatively, when 25B is set, the output of the set RS flip-flop 25A or 25B is configured to act on the control section 8 as a control signal for switching the selected column to the sold-out state. Also, 26 and 27 are a of relay 11A.
Contacts 28 and 29 are a contacts of the relay 11B.

With this configuration, the output of the abnormality detection device 22 acts on the control unit 8 as follows. Figure 5a
5 shows the output of the dispensing confirmation switch 13A, FIG. 5b shows the energization period to the electric motor 10A, FIG. 23, t represents the time required for the payout confirmation switch 13A to detect the start of movement of the pusher 17 after the start of energization. 5e shows a reset instruction signal of the bend signal 7A sent from the control section 8 to the sales price setting section 7, FIG. 5f shows the bend signal 7A, and FIG. It represents the period in which Selection pushbutton switch 3
If A is operated, the electric motor 10A starts to be energized and the output of the bend signal 7A is reset. When it is detected that the pusher 17 has started moving (time I in FIG. 5a), the timer 23 starts measuring time. During normal sales operation, the product delivery confirmation switch 13A detects the return of the pusher 17 before the timer 23 detects the elapse of the specified time T, and the timer 23 is reset. Further, when the payout confirmation switch 13A detects the return of the pusher 17, the control section 8 clears the input amount information held in the sales price setting section 7 to prepare for the next sales operation.

On the other hand, the movement of the pusher 17 is blocked due to the product 15 getting caught, and the dispensing confirmation switch 13
If A is in an abnormal state of dispensing and does not detect the return of the pusher 17 within the specified time T of the timer 23, the timer 23 detects a time-up [Fig. 5d] and the selection column at that time, for example A
To force the column into a sold-out state, RS flip-flop 25A is set via AND gate 24A of AND gates 24A and 24B. When the control unit 8 detects that the output Q of the R-S flip-flop 25A is inverted to the "H" level, the power to the motor 10A is forcibly turned off, and the product is switched to a state in which the products in the A column cannot be dispensed. This is notified to the user by lighting the sold-out indicator lamp 4A. Furthermore, the control unit 8
- When it is detected that the output Q of the S flip-flop 25A is inverted to the "H" level, the sales price setting unit 7 is informed of the input amount information held at the time as shown in FIG. 5 f and g. Instructs to re-output the bend signal 7A. When the bend signal 7A is re-outputted in this manner, another product can be reselected without performing the operation of refunding the deposited money. In other words, by simply operating the selection pushbutton switch 3B, it is possible to receive the products in the B column.

In the above embodiment, the timer 23 is configured to start counting when the payout confirmation switch 13A or 13B detects the start of movement of the pusher 17 in each column.
The same effect can be obtained even if the timing is configured to start at the timing when energization to A or 10B is started or when the energization instruction signal is generated.

Effects of the Invention As described above, according to the present invention, if the product dispensing operation is not completed within the specified time of the timer, the control unit switches the column to the sold-out state, so that the product dispensing device of the selected column is not energized. It can be forcibly turned off to prevent the power source from overheating.

Furthermore, when the above-mentioned abnormal condition is detected, the control section resets the bend signal to the sales price setting section, so the user processes the refund as before, inserts the refunded coins again, and selects the product. You can reselect another product without having to go through the troublesome operations of
Compared to conventional vending machines, the operability is greatly improved, and it is possible to prevent users from losing their desire to purchase, thereby preventing a decline in sales.
