Next, the work process of the rice milling facility will be described with reference to FIG.
The user enters the operation room 22 of the building 20 and inputs a fee. Then, a cleaning process for starting the rotary valve 11, the first elevator 2 and the stone remover 3 is performed in the closed position H where the open / close door 16 closes the input surface of the input hopper 1. “Wait for about 20 seconds during cleaning now,” announces. Then, when the previous user's residual brown rice remains in the charging hopper 1, it is drawn out and shaken up by the stone lifting sorting plate 3 a of the first elevator 2 and the stone removing machine 3 and stored in the storage box 28. That is, the stone selected by the stone remover 3 during the rice milling operation and the residual brown rice that has passed through the stone remover 3 in the cleaning process are stored in a common storage box 28.

  When a set time (for example, 20 seconds) elapses, the cleaning process ends, and the rotary valve 11, the first elevator 2 and the stone remover 3 are temporarily stopped. Then, the open / close door 16 is raised from the closed position H to the open position K where the input surface of the input hopper 1 is opened. In conjunction with the opening of the open / close door 16, the open / close shutter 19 also moves to the open position of the white rice tank 10.

  When the brown rice brought by the user is put into the feeding hopper 1 and any one of a plurality of milling degree selection switches 25 (upper white 25a, standard 25b, eighth 25c) is selected, each part of the rice milling equipment is activated and the rice milling is started. Operation starts. At this time, when the grain discriminating sensor 14 discriminates the cereal as rice cake, the voice notification device 30 informs the user that “the rice is rice cake cannot be polished”, and the rice milling operation is not performed.

  When the rice milling operation is started, the brown rice in the charging hopper 1 passes through the first elevator 2 from the rotary valve 11, and is removed by the stone removal sorting plate 3 a of the stone removal machine 3. Is removed and stored in the brown rice tank 6 through the second elevator 5. The brown rice in the brown rice tank 6 is supplied to the rice mill 8 by the rotary valve 7 and subjected to the rice milling process. The rice bran generated by the rice milling process is sucked by the suction fan 9 and accommodated in a rice bowl chamber or a bag not shown, and the rice milled rice milled is discharged and stored in the white rice tank 10. When the user steps on the discharge pedal 10b linked to the white rice tank discharge shutter 10a formed at the bottom of the white rice tank 10, the white rice tank discharge shutter 10a is opened and accommodated in a bag or the like brought with the polished rice in the white rice tank 10. . At this time, when the discharge pedal 10b is stepped on, a switch (not shown) is turned on, and the white rice tank vibration motor 10c is activated to promote the discharge of the polished rice in the white rice tank 10.

  When the rice milling operation proceeds and the grain presence / absence detection sensor 13 detects that brown rice in the throwing hopper 1 is not detected, the vibration motor 15 is driven for a predetermined time to vibrate the throwing hopper 1 and the residual brown rice caught on the separation net 12. Or the grain caught by the grain presence / absence detection sensor 13 or the grain discrimination sensor 14 is dropped on the bottom of the feeding hopper 1. When the vibration motor 15 stops after a lapse of a predetermined time, the finishing operation process of the rice milling equipment is performed.

  The finishing operation process is a process for processing the brown rice remaining in the charging hopper 1 and discharging it to the white rice tank 10 so that there is no residual brown rice in the rice milling equipment. In the end operation step, first, the rotary valve 11 is stopped. And the stone discharge process and the remaining rice process of the stone remover 3 are performed. That is, in the stone discharging process, the stones accumulated on the rocking side of the swing sorting plate 3a are discharged to the storage box 28 by switching the storage box 28 side of the stone extraction switching valve 3b, and then the stone extraction switching valve 3b is passed through the remaining rice passage. The remaining rice that has been switched to the 31 side and is swung up by the swing sorting plate 3 a is discharged from the remaining rice passage 31 to the rice mill elevator 5.

  Then, when the stone discharging process and the remaining rice process are completed, the first elevator 2, the stone remover 3, and the second elevator 4 are sequentially stopped. Finally, the remaining brown rice is processed by the rice mill 8 and the rice mill 8 is stopped. The end operation process is ended. The stop timing of each device in the end operation process is configured to be performed by time control. If the operation time for the input fee has not elapsed after entering the end operation step, the fee to be returned is calculated and the coin is returned from the coin mech (not shown) to the change port 29. .

  If a set time (for example, 10 minutes) has elapsed after the end operation process is completed and no new charge or brown rice has been detected, it is determined that the user has finished the milling operation, and the door 16 is closed. Move to. Then, the opening / closing shutter 19 also moves to a position where the upper surface opening of the white rice tank 19 is closed.

  In the state where the grain presence / absence detection sensor 13 has not detected the detection of brown rice, that is, in the state where brown rice of a set amount or more is present in the charging hopper 1, The device stops operating (out of charge). At that time, when the user inputs an additional fee, each part of the rice milling equipment is activated to resume the rice milling operation. When the additional fee is not charged, the user operates the rice return switch 27 when the brown rice left in the charging hopper 1 remains, and the rotary valve 11 and the first elevator 2 are activated to start the charging hopper. The brown rice in 1 is returned from the return passage 18 to the return port 18a, and the user receives it in the bag brought into the loading hopper 1 and takes it home. However, if a set time (for example, 15 minutes) elapses, no additional fee is charged, and if the rice return switch 27 is not operated, the brown rice in the loading hopper 1 remains unchanged and the open / close door 16 moves to the closed position H. To do. Then, the opening / closing shutter 19 also moves to a position where the upper surface opening of the white rice tank 19 is closed.

The effect of this embodiment will be described below.
Before the brown rice brought by the user is thrown in, the cleaning process is performed to remove the brown rice of the previous user remaining in the throwing hopper 1 due to the stoppage due to the above-mentioned charge expiration. Therefore, mixing with the brown rice brought by the user and the residual brown rice of the previous user can be prevented. Further, since the door 16 is closed during the cleaning process, the user cannot put the brown rice brought into the feeding hopper 1, so that it can be prevented from mixing with the brown rice of the previous user. .

  Further, before the grain presence / absence detection sensor 13 detects that the brown rice in the feeding hopper 1 is less than the set amount and performs the end operation process, the feeding hopper 1 is vibrated by the vibration motor 15 so that the separation net 12 or It is possible to prevent brown rice caught by the grain presence / absence detection sensor 13 or the grain discrimination sensor 14 from dropping and remaining in the throwing hopper 1. Further, since the vibration motor 15 is disposed above the grain presence / absence detection sensor 13 and below the separation net 12, the vibration motor 15 gives a vibration effect to any of the separation net 12, the grain discrimination sensor 14, and the grain presence / absence detection sensor 13. Cheap. The vibration of the vibration motor 15 may also be performed during the cleaning process.

  In addition, since the opening / closing operation of the opening / closing shutter 19 of the white rice tank 10 and the opening / closing operation of the opening / closing door 16 of the charging hopper 1 are controlled in an interlocked manner, the white rice tank 10 is opened and the polished rice is stored only during the rice polishing operation. It is possible to prevent mischief into the white rice tank during non-milling operation.

Next, the work process of the rice milling equipment of FIG. 5 will be described.
In FIG. 5, the cleaning process is different from the operation process of FIG. That is, the cleaning process is performed after the opening / closing door 16 is closed after a set time has elapsed since the rice milling operation was stopped. In other words, by performing the cleaning process in anticipation that the user is no longer in the rice milling facility, the user has no waiting time for the time of the cleaning process, and it is quick while preventing mixing with the remaining brown rice of the previous user. Can be used for the milling work.

Next, another embodiment of the cleaning process will be described.
In the above description, when the cleaning process shown in FIG. 4 is finished, the rotary valve 11, the first elevator 2 and the stone remover 3 are stopped and then the door 16 is opened (FIG. 7A).

  As another example shown in FIG. 7B, when a fee is charged and the cleaning process is started, first, as described above, the rotary valve 11, the first elevator 2 and the stone remover 3 are activated with the open / close door 16 closed. Then, after the set time (for example, 6 seconds), the rotary valve 11 is first stopped, and the door 16 is opened while the first elevator 2 and the stone remover 3 are driven. When the user puts brown rice into the feeding hopper 1 and selects the milling degree selection switch 25, the rotary valve 11 is activated again and the rice milling operation is started as it is. With this configuration, since the brown rice brought into the input hopper 1 and the degree of milling can be selected during the cleaning process, the waiting time of the user in the cleaning process can be shortened.

  Moreover, in this Embodiment, although it is the structure which stores the remaining rice of a cleaning process in the storage box 28 of the stone punching machine 3, as shown in FIG. You may make it the structure which switches and accommodates by the switching apparatus 41 provided in a spout side. Further, in the configuration in which the grain feeding device is provided with a spiral (not shown) instead of the rotary valve 11, the spiral may be reversed and accommodated in a dedicated remaining rice receiving box (not shown).

  Further, even when the cleaning process is completed and the open / close door 16 moves to the open position H, the user manually performs the cleaning process when the user notices that the remaining brown rice still remains in the feeding hopper 1. A switch (not shown) may be provided on the operation panel 24. This manual switch can be used only when the opening / closing door 16 is open, and the cleaning process is performed only when the door is kept pressed, so that the unnecessary cleaning process can be prevented.
