Description

[Detailed Description of the Invention] <Industrial Application Fields> This invention relates to a vending machine that is equipped with an ice maker inside and sells slush ice cream when a coin is inserted.

More specifically, when slush ice is removed by a method other than the normal sales operation to clean or maintain the ice stocker in the vending machine, the sales counter does not count it as the number of sales, so there is no ice remaining. This invention relates to a vending machine that prevents troubles caused by discrepancies between quantity and number of counts.

<Prior art> Since the ice making capacity of the ice maker of the above-mentioned vending machine is limited, when slush ice cream is sold continuously in the summer, etc., the slush ice cream (hereinafter simply referred to as ice) in the ice stocker is becomes less,
Even if a coin is inserted and a sales request is made, the specified amount of ice cannot be sold. Therefore, a sales counter is installed inside the aircraft, and the sales counter adds up the number of sales, and when that value reaches a predetermined value,
The display indicates that sales have been discontinued when the amount of ice in stock is running low.

<Problem to be solved by the invention> However, although the above sales counter is designed to be reset when the ice stocker is full, it is necessary to install a counter inside the vending machine for cleaning and maintenance of the ice stocker, etc. If a large amount of ice is removed from the ice stocker by operating the continuous ice removal switch, the sales counter is configured so that it cannot be counted as the number of sales even though the ice has been removed. Ta. For this reason, when the operator forgets to operate the display to indicate that the sale has been discontinued, the display indicating that the ice is on sale remains displayed even though the ice cannot be sold, causing trouble.

The present invention was developed to solve these problems, and the amount of ice removed by operating the continuous ice removal switch is counted using pulse signals from an oscillation circuit in the same way as the number of sales during normal sales. The purpose of the present invention is to provide a vending machine that can prevent troubles caused by discrepancies between the amount of delivery and the number of sales.

<Means for solving the problem> In order to achieve the above object, this invention is a vending machine that is equipped with an ice maker and sells slush ice cream when a coin is inserted. A timer circuit that drives the slush ice supply device for a predetermined period of time in response to a sales start signal from a signal line connected to the sales control section, and an OR circuit that is connected to the signal line in parallel with the timer circuit. A sales counter circuit that adds up the number of start signals, a sales stop signal generation circuit that generates a sales stop signal when the sales counter circuit adds up a predetermined number of times, and a sales stop signal generation circuit that is inserted between the supply device and the timer circuit. Another OR circuit is connected to the input terminal on the opposite side of the input terminal of the above timer circuit,
Separately from the timer circuit, a drive circuit is provided in which a continuous ice transfer switch is inserted to continuously drive the supply device, and further, when the continuous ice transfer switch is closed, a pulse is generated at the same period as the driving time of the timer circuit. The oscillator circuit that generates the
It is inserted between the input terminal of the above-mentioned signal line of the circuit and the input terminal on the opposite side, and when the continuous ice discharging switch is operated, the ice discharging amount of the above-mentioned supply device is controlled by the above-mentioned oscillation circuit in the same manner as the number of sales during normal sales. It is characterized by the fact that it can be integrated using a counter circuit.

<Function> In the above configuration, when the continuous ice transfer switch is operated, the amount of ice to be transferred is determined by the number of sales by the transmitting circuit provided between the continuous ice transfer switch and the sales counter circuit. The ice stocker is replaced by the ice stocker and accumulated at the sales counter, and when the ice in the ice stocker runs low, a sales stop message is displayed to prevent trouble from occurring.

<Example> Hereinafter, the present invention will be described in detail based on drawings showing examples thereof.

FIG. 1 is an electric block circuit diagram of the vending machine of the present invention, and FIG. 2 is a timing chart of the continuous ice dispensing switch and the transmitting circuit of the vending machine of the present invention. In FIG. 1, reference numeral 1 denotes a supply device consisting of a solenoid valve, etc., for delivering ice from an ice stocker (not shown) in a vending machine. It is becoming driven.

One input terminal 2a of the OR circuit 2 is connected between the continuous ice removal switch 3 provided in the machine and the transmitter circuit 9, and the other input terminal 2b is connected to the output side of the timer circuit 4. There is.

The input side of the above timer circuit 4 is connected to another
It is connected to a signal line that sends a sales start signal to one input terminal 7a of the OR circuit 7.

6 is a sales counter circuit that counts and totals the number of times ice is sold; the input side of this sales counter circuit 6 is connected to the output terminal of the OR circuit 7, and the output side of the sales counter circuit 6 generates a sales stop signal. It is connected to the input side of the circuit 8. The input terminal 7b on the opposite side of the OR circuit 7 is connected to the output side of the oscillation circuit 9.

Next, the operation of the present invention will be explained. During normal ice sales, a sales start signal A is issued, and when the above signal A is input to the input terminal 7a of the OR circuit 7, a sales signal is sent from the output terminal of the OR circuit 7 to the sales counter circuit 6. The sales counter circuit 6 counts the number of sales once and starts adding up the number of sales. The above sales start signal A is applied to the timer circuit 4 at the same time as the above OR circuit 7.
This timer circuit 4 starts operating, and while this timer circuit 4 is operating, the OR circuit 2
A driving signal is sent to the supply device 1 via the.
Then, by driving this supply device 1, ice is carried out of the machine. The amount of ice at this time is controlled by the operating time of the timer circuit 4, so that a constant amount is always carried out.

Normally, the above operation is repeated, and when the sales counter circuit has accumulated a predetermined number of sales, a sales stop signal is generated from the sales stop signal generation circuit 8, and a display means (not shown) displays a message such as "Sales Stop". will be held.

When the operator cleans or maintains the ice maker, the operator closes the ice continuous transport switch 3 to continuously transport the ice in the ice stocker. At this time, the supply device 1 is connected to the OR circuit 2.
The transmission circuit 9 is continuously driven by a signal from the transmitter, but the transmitter circuit 9 is also energized. Therefore, the transmitting circuit 9 sends a pulse signal to the input terminal 7b once every time t, which is equal to the operating time of the timer circuit 4, as shown in FIG.
It is applied to the sales counter circuit 6 through an OR circuit 7. Therefore, even if the supply device 1 is continuously operated by closing the ice continuous delivery switch 3, the amount of ice delivered is counted as the number of sales in the same way as in normal sales.

Therefore, after the operator has finished cleaning and maintaining the inside of the ice maker, the sales stop signal generation circuit 8 will issue a sales stop signal without any operation until the ice that can be sold is accumulated in the ice maker. Eliminate trouble.

[Effect of idea]

Since the present invention is constructed as described above, the amount of ice delivered while the continuous ice delivery switch is operating can be counted by the sales counter circuit in the same way as during normal sales. This has the remarkable effect of preventing the occurrence of troubles due to discrepancies between the amount of ice transported by operation and the sales count.
