Further, as shown in FIG.
When the changeover switch S is set to the automatic operation position, the brown rice supplying device 50 (motor for horizontal feed screw conveyor, motor for first elevator, motor for stone removing device, etc.) is operated by ON / OFF operation of the sub supply switch 53. (Drive / stop), treat each ON / OFF operation of the rice polishing switch 44 and the supply switch 43 as an invalid operation, and stand by in a state where the brown rice supply device 50 and the brown rice extraction rice polishing device 51 are stopped and used by the money inputting means. After the charge is received, the brown rice removing rice-polishing device 51 (motor for rice-polishing device, motor for second elevator, etc.) is driven by the operation signal for pressing the whitening degree switch 42 to polish the brown rice. On the other hand, when the changeover switch S is set to the manual operation position, the ON / OFF operation of the rice polishing switch 44 and the supply switch 43 is treated as a valid operation to operate each device, and the ON / OFF operation of the sub supply switch 53 is performed. It may be treated as valid or invalid.

The operation sequence associated with the operation of the rice milling machine when the changeover switch S is set to the automatic operation position will be described with reference to the flowcharts of FIGS. In addition, the reference numerals of the respective members are omitted. First, as shown in FIG. 10, the output signal from the remaining amount sensor of the two storage tanks is insufficient for the unpolished rice with the indicator light in operation is turned on and the bill validator is powered off. It is determined whether or not the signal is an OFF signal indicating. If at least one OFF signal is output, even if the sold-out lamp corresponding to the corresponding remaining amount sensor is lit and the brown rice selection switch of the corresponding brand is pressed, the push-in operation signal is treated as invalid, Move on to. Also, when it is not OFF, that is, when the ON signal indicates that both of the storage tanks are full of brown rice, the next determination is performed. The judgment is
This is a determination as to whether or not the output signals from both remaining amount sensors are OFF signals. When both are OFF, both sold-out lamps are turned on, the business indicator lamp is turned off, and the process ends. On the other hand, if both are not OFF, when the customer presses the brown rice selection switch of the brand that corresponds to the sold-out lamp (which means that it is on sale) that is turned off, the state of accepting the push-in operation signal, so-called customer waiting It is in a state.

When the customer pushes the brown rice selection switch,
The pressed brown rice selection switch is turned on, the power of the banknote sorter is turned on to accept the insertion of money, and the banknote number display lamp displays 0. Next, when the 1,000-yen bill is inserted, the bill number display lamp displays 1, the timer starts counting, and all the whiteness degree switches are blinked so that the pushing operation of the whiteness degree switches is accepted.

If a 1,000-yen bill is further inserted before the grace time of the timer expires, the bill number display lamp displays the inserted number, and the timer starts counting the grace time again, as shown in FIG. Then, the process goes to the judgment as to whether or not the number of inserted sheets has reached the upper limit. When the inserted number reaches the upper limit value, the power of the bill sorter is turned off, the 1000-yen bill is not accepted thereafter, and it is determined whether or not the grace period of the timer has expired. Further, even when the number of inserted sheets has not reached the upper limit value, it is determined whether or not the grace period of the timer has expired.

When the grace period of the timer has not expired, when the desired whiteness degree switch is pushed, the pushed whiteness degree switch is turned on and the other whiteness degree switches are turned off. Also,
The power of the banknote sorter is turned off, the resistance motor is rotated so that the whiteness degree corresponding to the pressed whiteness degree switch is reached, and the force with which the resistance plate closes the outlet is changed, and the motor of the second elevator is turned on. . On the other hand, if the grace period of the timer has expired, turn off the power of the banknote sorter and rotate the resistance motor to change the force with which the resistance plate closes the outlet so that the whiteness corresponds to the standard whiteness switch. , Turn on the standard whitening degree switch, turn off the other whitening degree switches, and turn on the power supply of the motor of the second elevator. Next, the control device calculates the sales weight of brown rice commensurate with the input amount by multiplying the number of inserted 1,000 yen bills and the unit weight which is the set value. After that, the metering shutter of the storage tank that stores the brand of brown rice that was pressed at the beginning is opened, the indicator light during weighing is turned on, and it is determined whether or not the weight of brown rice has accumulated in the weighing device. If not reached, the process returns to the same judgment again. On the other hand, when the selling weight is reached, the opened measuring shutter is closed.

Subsequently, it is determined whether or not the remaining amount sensor of the storage tank of the closed weighing shutter is OFF. In the case of OFF, it is determined that the amount of brown rice is less than the maximum amount that can be sold in one purchase operation, and after the completion of the rice polishing process, the corresponding sold-out lamp is turned on and the process ends. On the other hand, when the remaining amount sensor is not OFF, the process is finished after performing the rice polishing process. It should be noted that the term "after the rice polishing process" means a certain amount of time from immediately after the rice polishing is completed until the customer finishes the process of refilling the bags of the rice polished in the guest room tank.

As shown in FIG. 12, the rice milling process is performed such that the dispensing shutter of the weighing device is opened and the weight of the weighing device is 0 kg.
Move to the determination of whether or not. When the payout shutter is opened, the brown rice is pulled up by the second elevator and supplied to the rice polishing apparatus. If it does not reach 0 kg, repeat the determination until it reaches 0 kg. When the weight becomes 0 kg, the payout shutter is closed, and it is determined whether or not the brown rice detection sensor of the rice polishing apparatus is turned on. If it is not turned on, this determination is repeated, and if it is turned on, the power of the motor is turned on to rotate the whitening roll of the rice polishing apparatus, the indicator light for measuring is turned off, and the indicator light for polishing rice is turned on. Subsequently, the process proceeds to the determination of whether or not the brown rice detection sensor of the rice polishing apparatus is turned off. If not, this determination is repeated. When it is turned off, the motor of the whitening roll is turned off to stop the rice polishing device, the motor of the second elevator is turned off, and the indicator light during polishing, the whitening degree switch and the charge indicator light are all turned off.

In the above description, it was assumed that rice should be milled. However, since brown rice is also included in the whitening degree switch, when brown rice is selected, after weighing with a weighing device,
By operating the shutter of the flow path switching device of the second elevator, the brown rice is discharged to the cabin tank without passing through the rice polishing device. Further, the money inserting means may be used in combination with a coin sorter as well as the bill sorter.

[0032]

According to the present invention, since the brown rice supply device can be operated by the sub supply switch of the second operation panel, the administrator operates the brown rice supply device on the second operation panel while the customer purchases the polished rice on the operation panel. You can do it, which is convenient because you can continue the business while supplying brown rice. Further, since the work of putting the brown rice into the brown rice supply device and the operation of operating the brown rice supply device can be performed in the machine room, the work of replenishing the brown rice becomes easier as compared with the conventional case.
