次に、図5に基づき精米設備の作業工程について説明する。
利用者は建屋20の操作室22に入り、料金を投入する。すると、開閉扉16が閉鎖位置Hから投入ホッパ1の投入面を開放する開放位置Kにすべく上昇する。開閉扉16の開放に連動して開閉シャッタ19も白米タンク10の開放位置に移動する。
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, 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.

利用者が持参した玄米を投入ホッパ1に投入して複数の精白度選択スイッチ25(上白25a,標準25b,八分25c)のいずれかを選択すると、精米設備の装置各部が起動して精米運転が開始される。このとき穀物判別センサ14が投入した穀物を籾と判別すると、音声報知装置30で「籾です精米できません」との旨を報知し、精米運転はなされない。   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.

精米運転が始まると、投入ホッパ1内の玄米はロータリバルブ11から第一昇降機2を経て、石抜機3の石抜選別板3aで石抜きされ、異物除去装置4で藁屑等の長尺物を除去され、第二昇降機5を経て玄米タンク6に貯留される。玄米タンク6内の玄米はロータリバルブ7で精米機8に供給され、精米処理がなされる。精米処理で発生した糠は吸引ファン9で吸引され、図示しない糠室や糠袋に収容され、精米処理された精白米は白米タンク10に排出され貯留される。利用者は白米タンク10の底部に形成する白米タンク排出シャッタ10aと連動する排出用ペダル10bを踏むことで、白米タンク排出シャッタ10aが開いて白米タンク10の精白米を持参した袋等に収容する。このとき、排出用ペダル10bを踏むと図示しないスイッチがONされ、白米タンク振動モータ10cが作動して白米タンク10内の精白米の排出促進が行なわれる。   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.

精米運転が進み、穀物有無検出センサ13が投入ホッパ1内の玄米無しを検出すると、振動モータ15が所定時間駆動して投入ホッパ1に振動を与え、分離網12に引っかかっている残留玄米や穀物有無検出センサ13や穀物判別センサ14に引っかかっている穀物を投入ホッパ1の底部に落下させる。所定時間経過して振動モータ15が停止すると、精米設備の終了動作工程を行なう。   When the rice milling operation proceeds and the grain presence / absence detection sensor 13 detects the absence of brown rice in the throwing hopper 1, the vibration motor 15 is driven for a predetermined time to vibrate the throwing hopper 1, and residual brown rice and grain caught on the separation net 12. Grains caught by the presence / absence detection sensor 13 and the grain discrimination sensor 14 are dropped onto 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.

終了動作工程とは、投入ホッパ1内に残り少なくなった玄米を処理して白米タンク10に排出する工程で、精米設備内に残留玄米が無いようにするためのものである。終了動作工程ではまず、ロータリバルブ11を停止する。そして、石抜機3の石排出処理と残米処理を行なう。すなわち、石排出処理では揺動選別板3aの揺上側に溜まっている石を石抜切替弁3bの貯留箱28側切り替えで貯留箱28に排出し、次いで、石抜切替弁3bを残米通路31側に切り替えて揺動選別板3aで揺り上げられた残米を残米通路31から精米昇降機5に排出される。   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.

そして、石排出処理及び残米処理が終了すると第一昇降機2、石抜機3、第二昇降機4と順次停止し、最後に精米機8で残りの玄米を精米処理して精米機8を停止すると終了動作工程を終了させる。終了動作工程の各装置の停止のタイミングは時間制御で行なう構成としている。なお、終了動作工程に入った段階で投入料金分の運転時間を経過していない場合には、返却すべき料金を演算してコインメック(図示せず)から釣銭口29にコインが返却される。   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. .

終了動作工程が終了して設定時間(例えば10分)が経過して、新規の料金や玄米の投入を検出しないと、利用者が精米作業を終了して帰ったと判定して開閉扉16が閉鎖位置Hに移動する。すると、開閉シャッタ19も連動して白米タンク19の上面開口部を閉鎖する位置に移動する。あるいは開閉シャッタ19を閉じるタイミングとして、別実施例として操作室22に利用者の有無を検出する人検知センサ(図示せず)を設け、人検知センサ(図示せず)が利用者が帰ったと判定したら開閉シャッタ19を閉じる構成でも良い。   If a set time (for example, 10 minutes) has passed after the end operation process has ended and no new charge or brown rice has been detected, it is determined that the user has finished the milling work and returned and the door 16 is closed. Move to position H. Then, the opening / closing shutter 19 also moves to a position where the upper surface opening of the white rice tank 19 is closed. Alternatively, as a timing for closing the opening / closing shutter 19, a human detection sensor (not shown) for detecting the presence or absence of a user is provided in the operation room 22 as another embodiment, and the human detection sensor (not shown) determines that the user has returned. Then, the structure which closes the opening-and-closing shutter 19 may be sufficient.

穀物有無検出センサ13が玄米の検出無しを検出していない状態、すなわち、投入ホッパ1内に設定量以上の玄米が在る状態で、投入した料金分の運転時間が経過すると、精米設備の各装置の運転が停止する(料金切れ停止)。そのとき、利用者が追加料金を投入したら精米設備の装置各部が起動して精米運転を再開する。追加料金を投入しない場合には、利用者は投入ホッパ1内に投入した玄米を持ち帰るときには米返却スイッチ27を操作すると、ロータリバルブ11と第一昇降機2が起動し、切換弁17を返却通路18側に切り換えて投入ホッパ1内の玄米を返却通路18から返却口18aに返却し、それを利用者が投入ホッパ1上で持参した袋で受けて収容して持ち帰る。しかしながら、設定時間(例えば15分)経過しても追加料金が投入されず、また、米返却スイッチ27が操作されないと、投入ホッパ1内の玄米はそのままで、開閉扉16が閉鎖位置Hに移動する。すると、開閉シャッタ19も連動して白米タンク19の上面開口部を閉鎖する位置に移動する。   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 no additional fee is charged, the user operates the rice return switch 27 to take home the brown rice thrown into the loading hopper 1, so that the rotary valve 11 and the first elevator 2 are activated, and the switching valve 17 is returned to the return passage 18. The brown rice in the charging hopper 1 is returned to the return port 18a from the return passage 18 and received by the bag brought on the charging hopper 1 by the user. 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.

開閉扉16が閉鎖位置Hに移動すると、ロータリバルブ11と第一昇降機2と石抜機3を起動する清掃工程が行なわれる。すると、投入ホッパ1内に利用者の残留玄米が残留していた場合に繰り出されて第一昇降機2及び石抜機3の石抜選別板3aで揺り上げられ貯留箱28に貯留される。すなわち、精米運転中に石抜機3で選別した石と、清掃工程で石抜機3を経た残留玄米は共通の貯留箱28に貯留される。   When the open / close door 16 moves to the closed position H, a cleaning process for starting the rotary valve 11, the first elevator 2, and the stone remover 3 is performed. Then, when the user's residual brown rice remains in the charging hopper 1, the rice is drawn out and shaken by the stone lifting and 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.

設定時間(例えば20秒)が経過すると、ロータリバルブ11と第一昇降機2と石抜機3が停止して清掃工程が終了する。
この実施例の効果を以下説明する。
When the set time (for example, 20 seconds) elapses, the rotary valve 11, the first elevator 2 and the stone remover 3 are stopped and the cleaning process is completed.
The effect of this embodiment will be described below.

精米運転を停止してから設定時間を経過するか、又は人検知センサ(図示せず)が利用者を検知しなくなると、開閉扉16を閉鎖して清掃工程を行なう。すなわち、利用者が精米設備から居なくなったことを見計らって清掃工程を行なうことで、利用者が清掃工程の時間分精米運転における待機時間が無くなり、前の利用者の残留玄米との混合を防止しながら迅速な精米作業を行なうことができる。   When the set time elapses after the rice milling operation is stopped, or when the human detection sensor (not shown) stops detecting the user, the door 16 is closed and the cleaning process is performed. In other words, by performing the cleaning process in anticipation that the user is no longer in the rice milling facility, the user eliminates waiting time in the rice milling operation for the time of the cleaning process and prevents mixing with the remaining brown rice of the previous user. The rice milling can be done quickly.

また、穀物有無検出センサ13が投入ホッパ1内の玄米が設定量以下であることを検出して終了動作工程を行なう前に、振動モータ15で投入ホッパ1を振動させることで、分離網12や穀物有無検出センサ13や穀物判別センサ14に引っかかっている玄米を落下させ、投入ホッパ1内に残留することを防止することができる。また、振動モータ15は穀物有無検出センサ13より上方で、分離網12より下方に配置していることで、分離網12、穀物判別センサ14、穀物有無検出センサ13の何れにも振動効果を与えやすい。なお、振動モータ15の振動を清掃工程のときにも行なっても良い。   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.

また、白米タンク10の開閉シャッタ19の開閉動作と投入ホッパ1の開閉扉16の開閉動作を連動制御する構成とすることで、精米運転中だけ、白米タンク10を開口して精白米を貯留することができ、非精米運転時の白米タンク内への異物が混入することを防止することができる。   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 foreign matters from entering the white rice tank during non-milling operation.

次に図4の精米設備の作業工程について説明する。
図4では清掃工程を精米運転終了前に行なうことが、5の作業工程と異なるすなわち、利用者が持参した玄米を投入する前に、清掃工程を行なうことで、投入ホッパ1内に前の利用者の玄米が前述の料金切れによる停止で残留している場合に、それを除去することで、利用者の持参玄米と前の利用者の残留玄米と混合することを防止することができる。また、清掃工程を行なっているときには開閉扉16を閉鎖しているため、利用者は持参した玄米を投入ホッパ1に投入できないため、前の利用者の玄米と混合することを防止することができる。
Next, the work process of the rice milling equipment of FIG. 4 will be described.
In FIG. 4, the cleaning process is different from the work process 5 before the rice milling operation is finished. That is, the cleaning process is performed before putting the brown rice brought by the user into the feeding hopper 1. When the brown rice of the user remains due to the stoppage due to the above-mentioned charge expiration, it can be prevented from mixing with the brown rice left by the user and the previous user. 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. .

次に、清掃工程の別実施例について説明する。
図4に示す精米運転開始前の清掃工程が終了すると、ロータリバルブ11と第一昇降機2と石抜機3とを停止してから開閉扉16を開放する構成としている(図7A)。
Next, another embodiment of the cleaning process will be described.
When the cleaning process before the start of the rice milling operation shown in FIG. 4 ends, the rotary valve 11, the first elevator 2, and the stone remover 3 are stopped and then the door 16 is opened (FIG. 7A).

図7Bに示す別実施例として、料金を投入して清掃工程を開始すると、まず前述と同様に、開閉扉16を閉鎖状態でロータリバルブ11と第一昇降機2と石抜機3が起動する。そして、設定時間(例えば6秒)後にまずロータリバルブ11を停止し、第一昇降機2と石抜機3を駆動した状態で、開閉扉16を開放する。そして、利用者が玄米を投入ホッパ1に投入して、精白度選択スイッチ25を選択するとロータリバルブ11を再度起動してそのまま精米運転を開始する。この構成により、清掃工程の途中で持参玄米の投入ホッパ1への投入と精白度の選択を行なうことができるため、清掃工程による利用者の待機時間が短縮することができる。   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 can be selected and the degree of whitening can be selected during the cleaning process, the waiting time of the user during the cleaning process can be shortened.

また、本実施の形態では、清掃工程の残米を石抜機3の貯留箱28に貯留する構成であるが、図8に示すように別途専用の残米受箱40を設けて第一昇降機の投口側に設ける切換装置41で切り換えて収容する構成にしても良い。また、穀物繰出装置をロータリバルブ11の替わりにラセン(図示せず)を設ける構成においては、ラセンを逆転して専用の残米受箱(図示せず)に収容する構成にしても良い。   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).

また、清掃工程が終了して開閉扉16が開放位置Hに移動しても投入ホッパ1にまだ、残留玄米が残っていることを利用者が気がついたときに、利用者が手動で清掃工程を行なうためのスイッチ(図示せず)を操作盤24等の操作室22側に設けても良い。この手動スイッチは開閉扉16が開放しているときだけ使用できる構成とし、押し続けているときだけ清掃工程を行なうようにするか、押すと設定時間(例えば20秒)清掃工程を行なってから停止する構成にすることで、精米運転をしないときに無用に清掃工程が行なわれることを防止することができる。   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) for performing the operation may be provided on the operation chamber 22 side such as 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 opening / closing door 16 is kept pressed, or when it is pressed, the cleaning process is performed after a set time (for example, 20 seconds). By adopting such a configuration, it is possible to prevent the cleaning process from being performed unnecessarily when the rice milling operation is not performed.
