It is interposed in the current-carrying circuits 3c and 33d. Next, the sales operation of the sales apparatus having the above configuration will be explained.

When a coin is inserted into the regular coin slot, the coin passes through a coin sorter (not shown) that determines whether the coin is acceptable or not, and then the coin switch 32 is operated and the coin is temporarily stored in the storage unit 27. When the switch 32 operates, a current flows through the power source, the coin switch 32, the first switch R2 of the relay R2, one relay R, one diode D, and the power terminal L2, and the relay R switches its own first switch RH. to form a self-holding circuit. In addition, due to the operation of relay R, current flows from relay R8 to power supply terminals L and L2 via third switch Rr3 of relay R, first switch R7- of relay R7, and the first switch R8-, A self-holding circuit is formed at , and the plunger type solenoid 40 is operated by the second switch R8-2 of the relay R8 to close the closing row 3. Furthermore, each sold-out detection switch 35'a...35'd
and each sellable display lamp 15 to 18, the second of relay R,
Switch R. Current flows through -2. If we continue the explanation assuming that the selection button 14d among the selection buttons 14a to 14d is then operated, the corresponding selection switch 36
b, 37b operate, and the power terminal L-switches 34a to 3
4d series circuit, selection switches 35d, 35c, 35b
- Sell-out switch 35d - Third switch Rs2-3 (normally closed contact) of sales prohibition relay Rs2 - Plunger type solenoid 33b - Relay R. The second switches R, -2 - power supply terminal L are energized, and the solenoid 33b operates to connect the power supply L - switches 34a, 34b - the third switch Rs2-3 of the prohibited sale relay Rs2 - solenoid 33b -
The second switch R of relay R. -2-A current flows through the power supply terminals, and a current flows through the switch 34'b, the relay R3, and the diode D2.

Then, by operating the solenoid 33b, one droplet 11 is discharged from the storage section 10. Relay R2 cuts off the power to relay R, but relay R,, relay R2
etc., the power is cut off after a certain period of time by a delay circuit. Further, the selection switch 37b operates the relay R3, and the first switch R3- operates the motor M. The operation of the motor M causes the connecting pins 23, 23' to operate, lowering the guiding pin 22 and raising the guide pin 21 at the same time. In other words, cam switch CS
At W, the motor M is driven so that the guide shaft 22 is lowered to the bottom dead center. When the guide pin 21 rises and the guide village 22 descends, the moth 11 falling in a long state in the transverse direction of the open row 7 contacts the guide pin 21 from the center to the outlet side, and this contact portion A rotational force is applied to the heating coil 19 so that the grain is accommodated in the heating coil 19 in the vertical direction, and the grain is positioned on the receiving plate 25 of the induction village 22 . There is 1 grain on the receiving plate 25.
1 is located, the scale detection switch CSS, which detects that the cage 11 is inside the coil 19, operates and the structure 11 is activated.
When there is a drink in the saddle and it has a predetermined weight, the weight overcomes the force of the spring 26 and the receiving plate 25 descends, causing the saddle weight detection switch C to be activated.
Operate WS.

As the motor M operates, the pulse switch P operates to energize the relay R4, and the timer switch L-first switch R4- of the relay R4 and one delay relay R. the first of
Switch R. -, a self-holding circuit for relay R4 is formed. Then, due to the operation of relay R4, relay R4
The relay R5 operates via the second switch D4-2 and the moth weight detection switch CWS, and the third switch R
4-3 and the timer motor T via the positive detection switch CSS.
After M, delay relay Ro, heating indicator lamp 19 and delay timer Ro are operated, the relay is exhausted. When the timer motor TM operates and the timer switch T operates, the timer motor TM, delay relay RD, relay horse, and heating indicator lamp 19 are energized through the timer switch T, and then the timer switch L operates and the relay R4 self-energizes. Release the hold. By operating the relays R5 and R6, the heating device 38 is energized and heats Satoshi 11. Further, the fourth switch P5-4 of the relay R5 and the timer switch L are closed, the solenoid 30 is energized, the opening/closing plate 28 is operated, and the coins stored in the temporary storage section 27 are collected. When the timer switch L is operated and the motor M is re-driven, the transfer plate 22 is raised and the guide pin 21 is lowered, causing the heating element 11 to fall toward the passage 20 side and moving the rice cake 11 up and down to the outlet 16. The sales operation is completed by sending the product out so that it is reversed. Note that the solenoid 31 is energized by the timer switch T5 and the opening/closing plate 29 is opened, but this is irrelevant if the bonito 11 has a predetermined weight. At the same time, relay R7 is energized to release the self-holding of relay R8, cut off energization to solenoid 40, and release coin slot 13 from closing. The delay relay Ro operates for a certain period of time after being energized, and is set slightly longer than the operation of the timer switch T. Further, if the beard 11 discharged from the storage section 10 does not have a predetermined weight, the relay R5 is deactivated and the heating device 40 is not activated.
However, the timer motor TM is operated in a cycle, operating the solenoid 31 with the timer switch T5, opening the opening/closing plate 29 of the temporary holding section 27, returning the stored coins to the return row 5, and operating the relay R7. This is to release the coin slot 13 from closing. Note that the key 11 is sent to the outlet 15 without being heated. Next, to explain the case where the product in the d column of the double serpentine truck column 10 that was currently being sold has run out and the product is replenished, the detection means S and 2 are activated and a current flows to the sales prohibition relay Rs2. The first switch Ps2- of the sales prohibition relay Rs2 forms a self-holding circuit, and the second switch Rs2- of the sales prohibition relay Rs2 forms a self-holding circuit.
The sales prohibition timer TMs2 is operated through the switch Ps2-3, and the operation circuit of the plunger type solenoid 33b is opened by the third switch Ps2-3. Therefore, even if the corresponding selection button 14b is operated, the plunger type solenoid 33b is inoperative. Approximately 4 minutes after the sales prohibition timer TMs2 is activated, the switch Ts2 is engaged to release the self-holding of the sales prohibition relay Rs2, thereby canceling the sales prohibition of column b. As mentioned above, in the present invention, if there is not a predetermined weight of the contents to be sold, the amount equivalent to the input amount will be returned, so there will be no inconvenience to the bidder, and if there is not a predetermined amount of contents in the tower 11. This also prevents the problem of overheating and causing burns. Further, in the embodiment, the temporarily reserved coins are returned, but the coins may be paid out from the change. Additionally, columns that have been refilled with ant products will be prohibited from selling for a certain period of time, so when selling cold products, it will be possible to sell products that have been cooled below a predetermined temperature, and when selling them after heating. Since the temperature before heating is constant, there is almost no variation in temperature rise during heating depending on the product.

As is clear from the above embodiments, the vending machine vending control device according to the present invention is provided with a detection means for detecting that a product is filled in the product filling port, and a column and a column, and a countermeasure is taken when the detection means is operated. Each column is equipped with a prohibition switch that prohibits the sale of the columns and a timer device that releases the prohibition switch after a predetermined period of time has elapsed, and a sales mechanism that cools, heats, or warms the products in each column and sells them. When replenishing products, it is not necessary to stop selling all columns as in the past, but only the corresponding column is stopped selling for a certain period of time. This improves the operating rate of the vending machine, and also allows the vending machine to be refrigerated or refrigerated for a certain period of time using a timer device. Because of heating, especially when selling products heated after storing them in the refrigerator, the desired temperature before heating can be kept almost constant for each product, and the temperature of the products will not rise abnormally due to insufficient cooling. , which has various advantages.
