And

  Further, a return switch 8 for taking out the residual brown rice remaining in the charging hopper 2 from the return port 7 to the outside of the machine is provided, and the door 5 is automatically closed after the return switch 8 is operated.

  In the rice milling action as described above, when the operation time for the fee has elapsed and the rice milling operation has stopped, when the residual brown rice remaining in the charging hopper 2 is taken out from the return port 7 to the outside, the return switch 8 is operated. To do. When the return switch 8 is turned on, the door 5 is closed when it is detected by the brown rice sensor 6 that there is no residual rice in the throwing hopper 2. When the brown rice sensor 6 detects residual rice, the door 5 is kept open.

  Further, by operating the cleaning switch 11 or closing the door 5, a small amount of residual brown rice in the charging hopper 2 is cleaned and conveyed via the elevator 9 and is taken out and stored in the residue container 10. Further, in this embodiment, it is also possible to provide a take-out shooter 37 and the like for taking out and discharging the residue container 10 prepared in the external operation chamber 19 directly by the switching valve 13 at the outlet of the elevator 9. The small amount of residual brown rice here is a small amount of brown rice that does not turn on the brown rice sensor 6.

  In the cleaning process as described above, the operation of the cleaning switch 11 causes a transfer auger, which is a feed mechanism for feeding and transporting the remaining brown rice in the feed hopper 2 and the lifted rice hopper 2, the elevator 9, the switching valve 13, and the take-out shooter. The residue container 10 is taken out and accommodated through 37. Such cleaning and conveyance is also performed when a small amount of residual brown rice in the charging hopper 2 is conveyed through the elevator 9 after the door 5 is closed.

  By introducing a rice milling charge corresponding to the amount of brown rice for performing rice polishing into the coin insertion slot 25, the door 5 of the insertion slot 4 is opened, and the brown rice from the insertion slot 4 to the input hopper 2 is transferred. The introduction door 5 can be closed by the operation of the door opening / closing switch 30 after the start of the rice milling. This door 5 is automatically detected by the signal from the coin mech 3 when the brown rice sensor 6 after the rice milling action detects that there is no brown rice, or when the operation time of the rice milling apparatus 1 has elapsed for the input fee. To be closed.

When the brought-in brown rice is milled, a rice milling fee (coins) corresponding to the amount of brown rice to be polished is inserted into the coin insertion slot 25. With this charge input, the feed and transfer auger 12, the rice milling device 1, the stone extraction and sorting device 15, the elevators 9 and 16 and the like are operated, and the input door 5 of the brown rice input port 4 is opened. Brown rice can be introduced into the introduction hopper 2 from the section 4. A predetermined amount of brown rice is charged into the charging hopper 2 through the brown rice charging port 4 where the door 5 is opened. Here, when the milling degree selection switch 28 is selected and operated, the milling action of the brown rice by the milling apparatus 1 or the like is performed. (Steps S1, S2)
When the amount of brown rice brought in is large and additional rice milling is performed, the initial rice milling is detected by the coin-feeding sensor of the coin mech 3 by inserting an additional rice milling fee into the coin insertion slot 25 before or after the completion of the initial rice milling. The charging door 5 of the brown rice charging port 4 is opened by the output from the controller 31. Here, by adding additional brown rice from the brown rice input port 4 to the brown rice hopper 2 and operating the milling degree selection switch 28, the rice milling device can be driven to continue the additional rice milling action. (Step S3)
Further, when the door opening / closing switch 30 capable of opening the closing door 5 during the rice milling operation is provided, as described above, the closing door 5 during rice milling apparatus operation can be polished by operating one of the milling degree selection switches 28. Although it is maintained in the closed state when the device 1 is driven, it can be opened by operating the door opening / closing switch 30. Therefore, it is convenient when adding additional brown rice to the brown rice hopper 2 and continuing the milling. is there.

  Therefore, the door opening / closing switch 30 can be configured to open the closing door 5 using the whiteness selection switch 28, and other switches can be used without providing a special switch. It is possible to make it easy to add the additional brown rice.

As described above, when the rice milling user brings brown rice and inserts a coin of a predetermined fee into the coin insertion slot 25, the door 5 of the insertion slot 4 opens, so that the brown rice is introduced from the insertion slot 4 to the insertion hopper 2. Can be thrown in. Here, the rice milling device 1, the groining machines 9, 16, and the stone extraction / separation device 15 are driven by pressing the rice milling self-selection switch 28 to start the rice milling operation, and the white rice is taken out into the white rice hopper 23. Can do. (Step S1)
The amount of brown rice in the input hopper 2 is managed by the brown rice sensor 6, and if this detected brown rice is present, the rice polishing operation is continued during the operation time of the coin mech 3, and the rice polishing operation is stopped when a predetermined operation time has elapsed. (Step S2). If an additional fee is inserted into the coin insertion slot 25 when the operation is stopped at this time, the rice milling operation is further continued. When the return switch 8 for returning the residual brown rice is turned on during the rice milling operation, the brown rice remaining in the feeding hopper 2 by the detection of the brown rice sensor 6 is converted into the sown grain machine 9 and the switching valve 13. It is possible to take out from the return port 7 to the return port 7 prepared in advance on the top of the loading hopper 2 through the return path 32 and the like switched by (step S3). At this time, the brown rice sensor 6 detects the presence or absence of brown rice. When the brown rice is present, the door 5 of the slot 4 is opened, and when there is no brown rice, the door 5 is closed. The door 5 is closed and the cleaning process is started (step S4). For example, the transfer auger 12, the elevator 9 or the like is driven to store the hopper residual rice in the residue container 10, so that A cleaning operation for removing a small amount of residual brown rice remaining in the elevator 9 is performed. Therefore, it can prevent mixing with the brown rice brought by the next user.

  If the brown rice sensor 6 does not detect the remaining rice in the throwing hopper 2 during the rice milling operation, the swing motor 33 is driven to swing the swing net 34 for a predetermined time, and the predetermined rice polishing is completed. The end operation process for operating is operated (step S5). Then, the door 5 of the inlet 4 is closed as the operating time for the fee passes, and the cleaning process is performed (step S4).

  In the rice milling machine as described above, when only a small fee less than the usage fee of brown rice introduced by the user is charged, brown rice remains in the charging hopper 2 and the operation is stopped. After this stop, the user can take out the residual rice by pushing the return switch 3 which is an operation button at the time of take-back operation. When the brown rice is lost in the charging hopper 2, the charging port 4 After closing the door 5, the transfer auger 12, the groining machine 9, the switching operation of the switching valve 13, and the like are automatically performed, and the cleaning action is performed. When the brown rice sensor 6 detects that brown rice remains in the charging hopper 2, the door 5 does not close. Even if the amount is small, brown rice may remain in the input hopper 2 after the residual rice is brought home. By removing it by performing a cleaning process, the subsequent user does not feel uncomfortable.

  In the case of restart after operation stop due to the expiration of the charge, since the same user does not need to clean the charging hopper 2, etc., this cleaning is not performed. Shorten the time, prevent the operating rate from decreasing, and shorten the waiting time of customers.

  In addition, when the brown rice sensor 6 detects brown rice due to shutdown due to out of charge, but the amount of brown rice remaining in the input hopper 2 is small (for example, 1.5 kg or less), the amount of rice necessary for batch rice polishing May not be secured. In such a case, brown rice is likely to be mixed with white rice. Therefore, when the amount of residual rice in the input hopper 2 is small, the operation cannot be started, or a warning is given by the audio device 35 or the like so that the user can take it home as returned rice. Control.

  Next, mainly in FIG. 6, a foreign matter sensor 36 is provided on the bottom surface 38 of the elevator 9 for the stone extraction and sorting device 15. The foreign matter sensor 36 detects foreign matter such as powder and liquid sent to the groining machine 9 by the rotary valve of the charging hopper 2, the transport auger 12, etc., and issues an alarm. This is because the rotary valve, the transfer auger 12 and the like have a large transfer gap, and it is difficult for the brown rice sensor 6 and the input port 4 sensor to detect powder or liquid accurately.

  As described above, by providing the cleaning switch 11 on the operation panel 24, residual rice or the like is transported inside the apparatus or into the hopper 2 and discharged to the residue container 10 at the bottom of the stone extraction and sorting apparatus 15.

  Further, during such a cleaning operation, when the brown rice sensor 6 of the feeding hopper 2 is turned on from OFF during rotation of the rotary valve or the conveyance auger 12, it is determined that the user has introduced the brown rice, and the rotary rice is immediately turned. The drive of the valve and the transfer auger 12 is stopped. Alternatively, after confirming that the brown rice sensor 6 of the charging hopper 2 is OFF for a certain time, the door 5 of the charging port 4 is opened. When the user quickly puts brown rice into the charging hopper 2, the brown rice is discharged into the residue container 10.

  Further, during such a cleaning operation, pressing the milling degree selection switch 28 stops the cleaning operation, and turning on the switch 28 button makes automatic rice milling impossible, and the cleaning operation becomes unnecessary. .
