Next, the sales operation will be explained. When a regular coin is inserted into the 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 stored in the temporary storage section 27.

When the switch 32 operates, the first switch R2- of the fin source end L-coin switch 32-relay R2, -relay R,
A current flows through one iotad D, one power supply L, and the relay R.
forms a self-holding circuit via its own first switch RH. Also, due to the operation of relay R, relay R8 is activated by relay R.
A current flows through the third switch R, -3 of , and the first switch R7- of the relay R7 to the power supply terminal L,, -, and a self-holding circuit is formed at the first switch R3-, of the relay R7. At the same time, the plunger type solenoid 40 is operated by the second switch R8-2 of the relay R8 to close the input port 13. Furthermore, each sold-out detection switch 35'a...
- Current flows through 35'd, each sellable indicator lamp 155-18, and the second switch R, -2 of relay R.
After that, selection button 14 among selection buttons 14a to 14d
Continuing the explanation assuming that b is operated, the corresponding selection switches 36b and 37b operate 0, and the series circuit of the power terminal L-switches 34a to 34d, selection switches 35d,
35c, 35b - sold-out switch 35b - plunger type solenoid 33b - relay R. The current flows between the second switch R, -2 and the power supply terminal L2, and the solenoid 33b operates, and the current flows between the second switch Rr2 of the power supply machine L, the switch 34a, 34b, the solenoid 33b, and the second switch Rr2 of the relay R. current, and current flows through switch 34'b - relay R3 - diode D2.

Then, by operating the solenoid 33b, one can 11 is ejected from the storage section 10. Relay R2 cuts off the power to relay R, but relay R, , relay R
The second, etc. are configured so that the power supply is cut off after a certain period of time by a delay circuit. Further, the selection switch 37b operates the motor R3, and the first switch R3-3 operates the motor M. Due to the operation of this motor M, the connecting village 23
, 23' are operated to lower the yielding village 22 and raise the guide pin 21 at the same time. The operation of the motor M causes the guide cup 22 to be driven to the bottom dead center by the cam switch CSW. When the upper sample guide pin 21 is raised and the guide punch 22 is lowered, the can 11 falling in a long state in the lateral direction through the Sekiguchi 17 comes into contact with the guide pin 21 from the center to the outlet side.
Using this contact part as a ball, rotational force is applied to the heating coil 1.
9 and accommodate the receiving plate 2 of the guide village 22 in the vertical direction.
5. The can is positioned above. When the can 11 is positioned on the receiving plate 25, the can detection switch CSS which detects that the can 11 is inside the coil 19 is operated, and when the can 11 contains a beverage and has a predetermined weight, the force of the spring 26 is activated. The weight overcomes this and the receiving plate 25 descends, operating the can weight detection switch CWS.

With the operation of the motor M, the pulse switch P is operated and the relay R4 is energized, and the first switch R4- of the timer switch L-relay R4 and the first switch R4- of the delay relay Ro are activated.
A self-holding circuit for relay R4 is formed via switch Ro. Then, due to the operation of relay R4, relay R4
The relay R5 operates via the second switch R4-2 and the can weight detection switch CWS, and the third switch R
4-3 and the timer motor T via the can detection switch CSS.
M, delay relay Ro, heating indicator lamp 19 and delay timer R. After the operation of , relay R8 operates. When the timer motor TM operates and the timer switch T operates, the timer motor TM, delay relay Ro, relay R6, and heating indicator lamp 19 are energized through the timer switch T, and then the timer switch T2 operates and the relay R4 self-energizes. Release the hold. The heating device 38 is energized to heat the can 11 by operating the IJ Rays R5 and R6. Additionally, the fourth switch R5-4 of the relay R5 and the timer switch T4 are opened, and the solenoid 30 is energized.
operates to collect the coins stored in the temporary storage section 27. Then, timer switch T3 operates and motor M
When the can 11 is re-driven, the guide punch 22 is raised and the guide pin 21 is lowered, the can 11 is overturned toward the passage 20, and the can 11 is sent upside down to the outlet 16 to perform a selling operation. finish. Note that the solenoid 31 is passed through by the timer switch T5 and the opening/closing plate 29 is opened.
1 has a predetermined weight, it is irrelevant. At the same time, relay R7 is energized, releasing the self-holding of relay R8 and cutting off the energization to solenoid 40.
This is to release the closure of item 3. Delay relay R above. is a timer switch T, which operates only for a certain period of time after energization.
It is set slightly longer than the operation of . The storage section 10
If the released can 11 does not have a predetermined weight, the relay R5 becomes inoperative and the heating device 40 does not operate. However, the timer motor TM is operated in a cycle, operating the solenoid 31 with the timer switch, opening the opening/closing plate 29 of the temporary holding section 27, returning the stored coins to the return slot 15, and operating the relay R7. This is to release the coin slot 13 from closing. Note that the can 11 is sent to the outlet 15 without being heated. As described above, in the present invention, if the can to be sold does not have a predetermined weight, the amount equivalent to the amount invested is returned, so there is no inconvenience to the purchaser, and when there is less than the predetermined amount of contents in the can 11, This also prevents the disadvantage of overheating and causing burns. In the embodiment, temporarily held coins are refunded, but change may also be paid out. As is clear from the above embodiments, the present invention provides a vending control device for a vending machine, which includes a detection means for detecting the weight of a product in an induction heating coil disposed between a product storage section and a product takeout port. This system is equipped with a return method that returns the amount invested in purchasing the product if the weight is less than the set weight, which eliminates troubles with the installer due to selling products with insufficient weight to the purchaser. Since the amount equivalent to the amount invested is refunded, no inconvenience is caused to the trespassers, and moreover, the purchaser can use the money to purchase the product again.

In addition, if the product is underweight, it is guided to the product outlet without being heated, which eliminates the problem of abnormal heating and burns.
