Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an ice sales control method for a vending machine that supplies ice at the same time as beverage sales, or for a vending machine that only sells ice cubes.

Conventionally, the ice making machine used in a vending machine is placed on the ceiling of a water storage storage, and the ice making operation is controlled by a water storage switch.It is common that the ice making machine used in a vending machine is also controlled by the water storage switch. While the water storage switch is detecting ice, in other words, if the water storage is not full, ice will not be supplied, even though there is ice in the shrimp that is less than full. There is the inconvenience of having to stop supply.

In view of the above points, the present invention aims to sell ice efficiently by making it possible to supply ice even when the water storage is not full.

An embodiment of the present invention will be described in detail below with reference to the drawings.

Figure 1 shows the configuration of the ice maker (1), and (4) shows the auger (
5) is a cylindrical ice making unit with a cooling coil (6) wound around the outer wall, (7) is an auger motor, and (8) is a reduction gear mechanism.

(9) is a water storage tank, (1 is an agitator that rotates in conjunction with the auger (5) and
is a water field that is opened when ice is supplied, and α4 has the same water level as the ice making section (4) and is 9 degrees. Figure 2 shows the electric circuit of the Fi ice maker. When the water storage switch (2) is turned on, the congresor, thermotor (c), and auger motor a are driven to start ice-making operation, and the water in step 4) is poured into the ice-making section. When the water level decreases due to ice making, the water level switch (07) installed in the cylinder (14) excites the water level switch (07), which activates the water level switch (07).
19 is closed and the water solenoid valve is opened so that water is appropriately supplied to the ice making section (4). And ice storage* (
9) When ice is formed all at once and the plate (I) is pushed upward and the water storage switch (2) is turned off, both the compressor motor α9 and the auger motor a0 stop driving and the ice making operation ends.

Figure 5 is a block diagram showing the control circuit of an automatic han vending machine that sells iced drinks. I) is a carp/sensor that detects inserted coins and outputs a calculation signal, (A) is a calculation device that calculates the amount of money inserted and the amount of change, (C) is a sales price setting switch, and (F) is a change dispensing mechanism. be. and@
The control unit compares the input amount with the selling price and decides whether or not to sell based on the presence or absence of change.

A sales signal V is output for products that can be sold.

(C) is a sales signal relay that is excited by the sales signal V and outputs an AC sales signal V'; @ is a selection device that enables selection operations using the sales signal V'; (2) is responsive to selection operations. The sales control mechanism opens the beverage supply valve for a certain period of time to supply a predetermined amount of beverage. Selection signal sensor consisting of Otokagura (To)
is the AC sales start signal v that also occurs with the selection operation.
For example, it is a photocoupler sales start signal 7, which converts s' into a DC signal v8. Then, the control unit (c) uses the sales start signal v8 and the selection signal S to subtract the sales amount from the input amount using the calculation device ■, and controls the change dispensing mechanism (goods) to pay out the change amount when there is change i. It is something to do.

Also, (3) is a counting device that turns off the water storage switch (2).
l, when setting device r31) set r50JK,
I remember that it was possible to supply ice for 50 cups. In this example, it is assumed that ice for one supply is made every three minutes of the mine ice making operation, and therefore, the timer device (to) is activated when the signal I indicating the ice making operation is input continuously. , +1 to the counting device (3) every 5 minutes.
Outputs the addition signal. (To) is an ice switch that is installed on the front panel of the vending machine and is operated when the customer desires a water drink. (B) is an ice switch (To) operation signal and counting device (3) The AND gate where the ice supply ready signal that occurs when the number of supplies is memorized is input, (to) is A
AN to which the output of ND Genit (To) and selection signal S are input.
The D gate (to) is an ice supply timer that is driven for a certain period of time at the exit of the A-attached D gate (to). While the ice supply timer (2) is running, the water field drive device (b) operates to open the water field a3 and supply a predetermined amount of ice. In addition, the output of the AND gate (to) allows the counting device (3
) is designed to subtract 1 assuming that one cup of ice is supplied.

With the above configuration, when the power is turned on when there is no ice in the water storage (9), the water storage switch (2) is turned on and ice-making operation starts, and during this ice-making operation period, the timer device holder indicates that 3 minutes have elapsed. The counting device (3) counts the number of times it is supplied because it outputs a +1 addition signal every time it is supplied.

When the counting device (counting state other than 3mrOJ, that is, the number of times of supply is memorized), it outputs an ice supply ready signal to the AND gate (goods), and when the ice switch (to) is operated, the AND gate (goods) On the other hand, when a predetermined amount of money is put into the vending machine in this state, a sales signal V is generated in the control section (c), and when the customer performs a selection operation, a selection signal is generated. 8 was obtained.

When ice sui and chi (to) are operated along with the selection operation, muN
D gate (to) K output is obtained and ice supply timer (to)
is driven for a certain period of time, and the water world driving device (goods) is driven. Then, the sales control mechanism (2) is driven by the selection operation, and at the same time as the beverage is supplied, a predetermined amount of ice is also supplied by opening the water field I. In addition, the output of the AND gate (to) is introduced to the counting device (3) as a subtraction signal, so
) - Subtract the number of doses delivered. Therefore, even if ice is not produced until it reaches the water storage switch (2) during the ice operation period, it is counted by the needle counting device (3) and ice can be supplied within the number of good supplies. However, when the ice making cannot keep up with the supply, the counting device (3) subtracts, and the signal I! indicating that the counted value has become "rO"! At the event, the deposit amount will be returned to customers who wish to sell ice or ice that is out of ice. In this state, the ice supply ready signal is not generated in the counting device (3), so even if you operate the ice switch, the output is not obtained at the mND gate (to), and the water supply switch i- (to) is not output. ) is inactive and does not operate to supply ice. Furthermore, some vending machines dispense more drinks if they run out of ice.

This can be achieved by outputting the signal E to the sales system # mechanism (to) and slightly lengthening the opening time of the beverage supply valve.

When ice is made until the water storage (9) is full, the water storage switch (2) is turned off and the ice making operation is stopped, and the counting device (3) is set to "5" by the setting device (01).
0" is set. By the way, the water storage (9) is full.
However, it cannot be helped that the amount of ice varies each time, and this setting value of 5 Ω will not work in any case.
9) is the minimum value that can be supplied when it is full. From then on, every time ice is supplied, the K AND gate (
The counting device (3) is subtracted by the output of the water storage switch (2), and when ice making operation is started by turning on the water storage switch (2), the counting device (3) is incremented every 5 minutes and the water storage switch (2) is turned off.
"50" is set when j, .

According to the present invention described in detail above, ice can be supplied even if ice is not being made until it reaches the water storage switch, and ice can be sold efficiently. Moreover, since the ice inventory is managed by the counting device when the water storage switch is not reached, when the ice runs out, it is possible to display to the customer that ice cannot be supplied, thereby preventing problems related to ice sales.
