Description

【0001】
【発明の属する技術分野】
この発明は、穀粒を精白処理する精米施設に関するものである。
【0002】
【従来の技術】
コインあるいはプリペイドカ−ド等を投入することにより、投入した穀粒を精白する精米施設に関しては周知である。このような精米施設に関して、精米装置の原料貯留タンクに穀粒の有無を検知するセンサを設け、投入した穀粒を原料貯留タンクに投入開始すると、センサがONし、その後一定時間経過すると精米装置が起動し精米作業を開始するという技術が開示されている(特開平7−124486号)。
【0003】
また、顧客が精米施設に料金を投入し、原料投入ホッパに穀粒を投入すると、精米施設の装置各部が運転を開始し、供給ラセンあるいはロ−タリバルブ等の搬送手段で穀粒の搬送を開始するが、同時に精米装置の精白ロ−ルの回転駆動の有無を検出している。そして、精白ロ−ルがロック状態等で回転駆動しなかったことを検出すると、一旦精白ロ−ルを逆転した上で再度起動した上で、精白ロ−ルの回転駆動を検出するまでこれを所定回数繰り返す。それでも精白ロ−ルの回転駆動状態を検出できない時、精米装置のモ−タへの通電を遮断し、さらに所定時間遅れて穀粒の搬送手段である供給ラセン等が停止することにより、昇降機や精白室内の穀粒残留を少なくできるという技術が開示されている(特開平3−174255号)。
【0004】
【発明が解決しようとする課題】
精米施設を起動したとき、故障あるいはモ−タロック等で精白ロ−ルが回転駆動しない場合がある。また、特開平3−174255号公報のようにモ−タロック等で精白ロ−ルが回転駆動状態を検出しない際に精米装置のモ−タへの通電を遮断して起動そのものを停止する場合がある。
【0005】
このような場合において、特開平7−124486号公報については搬送手段で原料貯留タンクまで搬送し、そして一定時間原料貯留タンクに供給してから精米装置を起動するので、精米施設を起動してから精白ロ−ルが回転駆動までの時間、搬送手段は駆動している。従って、精米装置・精米施設が停止すると原料投入部から精米装置に至るまでの搬送経路に投入した穀粒が残留する。
【0006】
また、特開平3−174255号公報についても精白ロ−ルの起動と同時に搬送手段も起動するので、精白ロ−ルが再起動している間に搬送経路に穀粒が入り込んでしまう。従って、再起動後、精米施設が過負荷等で停止すると、同様に搬送経路に穀粒が残留する。その際、精米施設の管理者は精米施設のメンテナンスをすると同時に、残留した穀粒を取り出さなければならないが、搬送経路全般に穀粒が残留しているので、投入した穀粒すべてを取り出すのに手間がかかる。
【0007】
本発明は、精白ロ−ルの回転駆動状態を検出しない際に、一旦精白ロ−ルの起動を中止させた上で再度精白ロ−ルを起動させ、それを所定回数繰り返し、それでも回転駆動状態を検出しない場合には、強制的に精白ロ−ルの起動を継続させる構成の精米施設においては、起動の継続開始時以降に搬送手段を起動させることで、過負荷による精米施設の停止の際の搬送手段の経路における穀粒の残留量をより減少させることを目的とする。そしてこれらにより、作業者が精米装置・精米施設のメンテナンスをする際、投入した穀粒を原料投入部より回収できる割合を向上させることを目的とする。
【0008】
【課題を解決するための手段】
本発明は、上記の課題を達成するために次のような技術的手段を講ずる。請求項1においては、穀粒を投入する原料投入ホッパ(5)と、該原料投入ホッパ(5)内の穀粒を搬送するロータリバルブ(6)と、ロータリバルブ(6)で排出した穀粒を揚穀する石抜装置用昇降機(7)と、該石抜装置用昇降機(7)で揚穀された穀粒中の石を抜く石抜機(11)と、該石抜機(11)で石抜きされた穀粒を揚穀する精米装置用昇降機(8)と、該精米装置用昇降機(8)で揚穀された穀粒を精白ロール(15)で精米する精米装置( D )と、精白度を設定すると共に精白作業を開始する白度選択ボタン(34a),(34b),(34c)とを備え、該白度選択ボタン(34a),(34b),(34c)を操作すると精白ロール(15)が起動する構成とし、該精白ロール(15)が起動して検出回転駆動状態を検出手段(18b)が検出すると前記ロータリバルブ(6)、前記石抜装置用昇降機(7)及び前記精米装置用昇降機(8)が起動する構成とし、
前記検出手段(18b)が前記精白ロ−ル(15)の回転駆動状態を検出しない場合には、一旦前記精白ロ−ル(15)の起動を中止し、再度前記精白ロ−ル(15)を起動することを所定回数反復し、且つ、所定回数反復しても精白ロ−ル(15)の回転駆動状態を前記検出手段(18b)が検出しない場合には、精白ロ−ル(15)への通電を継続すると共に、前記ロータリバルブ(6)、前記石抜装置用昇降機(7)及び前記精米装置用昇降機(8)の起動を開始することを特徴とする精米施設とした。
【0009】
【0010】
【発明の作用】
請求項1においては、白度選択ボタン(34a),(34b),(34c)を操作すると精白ロール(15)が起動し、精白ロール(15)が起動して検出回転駆動状態を検出手段(18b)が検出するとロータリバルブ(6)、石抜装置用昇降機(7)及び精米装置用昇降機(8)が起動する。
検出手段(18b)が精白ロ−ル(15)の回転駆動状態を検出しない場合には、一旦精白ロ−ル(15)の起動を中止し、再度精白ロ−ル(15)の起動を所定回数反復し、精白ロール(15)が起動すると精米施設は通常の精米作業を行ない、所定回数反復しても精白ロ−ル(15)の回転駆動状態を検出手段(18b)が検出しない場合には、精白ロ−ル15への通電を継続すると共に、ロータリバルブ(6)、石抜装置用昇降機(7)及び精米装置用昇降機(8)の起動を開始する。
【0011】
【発明の効果】
本発明によると、穀粒を投入する原料投入ホッパ(5)と、該原料投入ホッパ(5)内の穀粒を搬送するロータリバルブ(6)と、ロータリバルブ(6)で排出した穀粒を揚穀する石抜装置用昇降機(7)と、該石抜装置用昇降機(7)で揚穀された穀粒中の石を抜く石抜機(11)と、該石抜機(11)で石抜きされた穀粒を揚穀する精米装置用昇降機(8)と、該精米装置用昇降機(8)で揚穀された穀粒を精白ロール(15)で精米する精米装置( D )と、精白度を設定すると共に精白作業を開始する白度選択ボタン(34a),(34b),(34c)とを備え、該白度選択ボタン(34a),(34b),(34c)を操作すると精白ロール(15)が起動する構成とし、該精白ロール(15)が起動して検出回転駆動状態を検出手段(18b)が検出すると前記ロータリバルブ(6)、前記石抜装置用昇降機(7)及び前記精米装置用昇降機(8)が起動する構成とし、
前記検出手段(18b)が前記精白ロ−ル(15)の回転駆動状態を検出しない場合には、一旦前記精白ロ−ル(15)の起動を中止し、再度前記精白ロ−ル(15)を起動することを所定回数反復し、且つ、所定回数反復しても精白ロ−ル(15)の回転駆動状態を前記検出手段(18b)が検出しない場合には、精白ロ−ル(15)への通電を継続すると共に、前記ロータリバルブ(6)、前記石抜装置用昇降機(7)及び前記精米装置用昇降機(8)の起動を開始することで、精白ロ−ル(15)への通電を継続した直後に過負荷等の異常により精米施設が停止した場合でもロータリバルブ(6)、前記石抜装置用昇降機(7)及び前記精米装置用昇降機(8)における穀粒の残留をより減少させることができる。したがって、精米施設を停止した際、管理者がメンテナンスをするにあたって、投入した穀粒を原料投入ホッパ(5)より回収できる割合を向上させることができる。
【0012】
【発明の実施の形態】
本発明の精米施設をの全体構成を図1から図4に基づいて説明する。図1は、精米施設を設置する建家の平面図で、内部は仕切壁1により操作室Aと機械室Bに分けられている。この操作室A側には、穀粒袋置き台2、操作盤3、白米タンク4等を設け、機械室B側には、原料投入ホッパ5、原料投入ホッパ5に投入した穀粒を搬送する搬送手段となるロ−タリバルブ6、石抜装置用昇降機7、精米装置用昇降機8、そして、穀粒中の石等を抜く石抜装置C、穀粒を精白する精米装置D、精米装置Dから発生した糠を処理する糠処理部E等を設けている。なお、搬送手段は前記ロ−タリバルブ6、各種昇降機6、7に限らずラセン・スロワ等を用いてもよい。
【0013】
図1に示すように、前記操作室A側から機械室B側に向かって、穀粒袋置き台2、原料投入ホッパ5をそれぞれ配置する構成とし、原料投入ホッパ5の下部には、原料投入ホッパ5に投入した穀粒を繰り出すロ−タリバルブ6を設けている。そして、ロ−タリバルブ6の排出側を石抜装置用昇降機7のホッパ部7aに連通させ、石抜機用籾摺昇降機7の上部は石抜装置Cに臨ませる。
【0014】
石抜装置Cは上から異物除去装置10、石抜機11を配設している。石抜機11は、図3にあるように、傾斜して配置している揺動選別板11a、その下方に配置している送風ファン11b等から構成される周知の構成で、揺動選別板11aの揺下側の排出口11cが精米装置用昇降機8のホッパ部8aに連通している。そして、精米昇降機8の上部を、精米装置Dの原料貯留タンク12に臨ませる。
【0015】
精米装置Dは、上から原料貯留タンク12、搗精部13を配置しており、搗精部13は、精白金網14に精白ロ−ル15、送穀ラセン16を内装し、駆動軸17で回転駆動する周知の形態である(図4、図5参照)。なお、前記駆動軸17には検出ボス18aと回転センサ(近接センサ)18bとを取り付け、検出ボス18aが回転センサ18bに近づくと回転センサのLED18cが点灯し、離れると消灯することにより、精白ロ−ル15の回転駆動の有無を検出するよう構成している(図6参照)。そして、前記搗精部13の出口側は、白米を取り出す白米タンク4に連通し、操作室A側より白米を取り出せるようになっている。なお、精米作業にて発生する糠は、糠搬送ファン(図示せず)で糠処理部Eに搬送されるか、糠切替シャッタ19を切り換えて客室取り出しサイクロン20を経て操作室側Aに搬送される。
【0016】
糠処理部Eは、サイクロン21、該サイクロン21より落下した糠を水平移送する糠移送ラセン22、該糠移送ラセン22を内装する糠移送樋23、該糠移送樋23の途中部と終端部に開口した糠排出部(図示せず)、該糠排出部より排出した糠を受ける糠袋24・24から構成されている。ところで、前記操作室A側の操作盤3は、その盤面には図7に示すように、故障警報ランプ30、コイン金額表示灯31、コインメック32、もち選択ボタン33、白度選択ボタン34a・34b・34c(本実施例では、上白・標準・8分の三段階に選択できる)、料金表(図示せず)、電流計35等を配設している。このコインメック32は精白作業開始手段であり、投入コインの識別部(図示せず)や投入コイン毎に作動するコインセンサ36等を備えている。そして、この操作盤3の内部には、各部駆動モ−タの駆動制御を行なうシ−ケンスによる制御部(CPU)40を備えている。
【0017】
図8に示すように、前記制御部(CPU)40には、コインセンサ36からの検出情報、白度選択ボタン34a・34b・34cからの籾・玄米の白度選択情報、回転センサ18bの検出情報、精米装置駆動モ−タ45の過負荷を検出する過負荷検出手段55からの検出情報等が入力インタ−フェイス39を介して入力される。
【0018】
一方、ロ−タリバルブ駆動モ−タ41への制御信号、石抜装置用昇降機駆動モ−タ42、石抜機用駆動モ−タ43、精米昇降機駆動モ−タ44への制御信号、精米装置駆動モ−タ45への制御信号、白度調節モ−タ46への制御信号、糠ラセン駆動モ−タ47、コイン引落し用アクチュエ−タ48等が出力インタ−フェイス49を介してある。
【0019】
次に、精米施設の作業行程について図2、図9に基づいて説明する。原料となる穀粒(玄米・もち)を原料投入ホッパ2に投入し(S100)、穀粒量に見合う運転時間を確保できるだけのコインをコインメック42の投入口に投入する(S101)。次に投入する穀粒がもちの場合はもち選択ボタン33を押す(S102)。そして白度選択ボタン44a・44b・44cのいずれかを選択し精白度を設定すると(S103)、白度調節モ−タ46が作動し圧迫板50の位置を設定する。これらの設定準備が完了すると(S104)、CPU40は投入コイン(100円硬貨)の枚数を読み込み、運転時間を算出し、当該算出時間にわたり駆動信号を出力し、装置各部は運転を開始する(S105)。
【0020】
原料投入ホッパ2に投入された穀粒(玄米・もち)は、ロ−タリバルブ6で石抜装置用昇降機7に搬送され、石抜装置用昇降機7のバケットコンベア(図示せず)で揚穀され、石抜装置Cの異物除去装置10に投入される。異物除去装置10で藁くず等が取り除かれ、石抜機11に供給される。石抜機11に供給された穀粒は、前記揺動選別板11aで揺動選別される。そこで、穀粒に混入している石等は、選別板揺上側に移動し、石抜排出口60より排出され、貯溜室61に貯溜される。一方、穀粒は、選別板揺下側に流下し、穀粒排出口11cより精米装置用昇降機8に供給される。
【0021】
精米装置用昇降機8で揚穀された穀粒は、精米装置Dに供給され、精白ロ−ル15と精白金網14との間で、設定された精白度になるよう表面糠層を剥離される。そして、精白された白米は白米タンク4に搬送され、適宜操作室A内にて回収できる。なお、精白ロ−ル15と精白金網14とによる精白作用の際、発生する糠等は、糠処理部Eに空気搬送され、サイクロン21を経て、糠移送樋23を糠ラセン(図示せず)で搬送され、糠袋24・24に回収される。
【0022】
運転各部は投入金額にて設定された時間が経過すると(S106)、まず、ロ−タリバルブ6が停止し、所定時間遅れて、石抜装置用昇降機7、石抜機11、精米装置用昇降機8、次いで精米装置D等が停止するものとし(S107)、石抜装置用昇降機7、精米装置用昇降機8、精米装置D内の残留穀粒を少なくできるようになっている。そして、精米作業をした結果、投入金額に達しなかった場合、コイン引落し用アクチュエ−タ48が作動し、釣銭が返却口(図示せず)より返却される。なお精白作業開始手段として、プリペイドカ−ド等を使用あるいは併用可能にしても良い。
【0023】
次に、発明の要部である精米施設の起動の際の駆動順序について図10に基づいて説明する。前記設定準備が完了すると(S104)、精米装置駆動モ−タ45に通電することにより精白ロ−ル15が起動し(S110)、前記精白ロ−ル15の回転センサ18bが回転駆動状態を検出する(S111)。そこで、精白ロ−ル15の回転駆動状態を検出すると搬送手段であるロ−タリバルブ6、石抜装置用昇降機7、精米装置用昇降機8が順次駆動し穀粒を搬送する(S112)。
【0024】
これにより、精白ロ−ルを搬送手段よりも先に起動することにより、精白ロ−ルの回転駆動あるいは非回転駆動状態の検出を搬送手段の起動よりも先にすることで非回転駆動状態の際、過負荷等の異常により精米施設が停止した場合、搬送手段に残留する穀粒の量を減少させることができる。また、ここで、精白ロ−ル15が過負荷等で回転駆動状態を検出しない場合であるが、その際には、ロ−タリバルブ6、石抜装置用昇降機7、精米装置用昇降機8を起動させない(S113)。
【0025】
このような構成にすることで、精米装置Dが停止した際、ロ−タリバルブ6、石抜装置用昇降機7、精米装置用昇降機8に穀粒が残留することが無い。一方、最初に精白ロ−ル15を起動させたときに起動せず、一旦精米ロ−ル15の起動を中止させた上で再度精米ロ−ル15を起動させ、精白ロ−ル15の回転駆動状態を検出するまでそれを例えば2回繰り返し、それでも回転駆動状態を検出しない場合には、強制的に精白ロ−ル15の起動を継続させる構成の精米施設について、図11に基づいて説明すると、最初に精白ロ−ル15を起動させたとき(S120)に精白ロ−ル15の回転駆動状態を検出する(S121)。そのとき、精白ロ−ル15の回転状態を検出できない場合、一旦精米ロ−ル15の駆動を中止させた上で(S122)再度精米ロ−ル15を起動させ(S123)精白ロ−ル15の回転駆動状態を検出する(S124)。この時、精白ロ−ル15の回転駆動を検出するまでは、ロ−タリバルブ6、石抜装置用昇降機7、精米装置用昇降機8も起動しない。そして、それでも回転駆動を検出しない場合には、例えば3回目に強制的な精白ロ−ルの起動開始以降(S125)にロ−タリバルブ6、石抜装置用昇降機7、精米装置用昇降機8を起動開始する(S126)。そして、強制的に精白ロ−ルを起動させ続けて過負荷等異常により精米施設が停止すると(S127)、精米作業は終了する。
【0026】
前述の精米施設は、精米施設を利用する作業者の為にできるだけ精米施設を停止したくないという意味がある他、強制的に精白ロ−ルの起動を継続すれば精白ロ−ルが回転駆動する場合があるということが背景にあるが、このような構成にすることで、精白ロ−ルの再起動中にはロ−タリバルブ6、石抜装置用昇降機7、精米装置用昇降機8に穀粒を搬送しないので、強制的に精白ロ−ルの起動を継続した直後に過負荷等の異常により精米施設が停止した場合において、穀粒の残留量をより減少させることができる。
【0027】
以上のことから本発明により、精米施設を停止した際、管理者がメンテナンスをするにあたって、投入した穀粒を原料投入部より回収できる割合を向上させることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a rice milling facility for whitening grains.
[0002]
[Prior art]
It is well known about a rice milling facility that whitens the input grain by inserting coins or prepaid cards. With regard to such a rice milling facility, a sensor for detecting the presence or absence of grain is provided in the raw material storage tank of the rice milling apparatus, and when the input grain starts to be fed into the raw material storage tank, the sensor is turned on, and after a certain time has elapsed, the rice milling apparatus Is started and rice milling is started (Japanese Patent Laid-Open No. 7-124486).
[0003]
Also, when the customer puts a fee into the rice milling facility and puts the grain into the raw material charging hopper, each part of the rice milling facility starts operation, and the transportation of the grain is started by the transportation means such as the supply spiral or rotary valve. However, at the same time, the presence or absence of rotational driving of the milling roll of the rice milling device is detected. When it is detected that the milling roll has not been rotated in a locked state or the like, the milling roll is reversed and then restarted, and this is repeated until rotation of the milling roll is detected. Repeat a predetermined number of times. If the rotational drive state of the milling roll cannot be detected yet, the energization to the motor of the milling machine is cut off, and the supply helix, etc., which is the grain conveying means, is stopped with a delay of a predetermined time. A technique that can reduce residual grains in the milling chamber is disclosed (Japanese Patent Laid-Open No. 3-174255).
[0004]
[Problems to be solved by the invention]
When the rice milling facility is activated, the milling roll may not be driven to rotate due to a failure or motor lock. Further, as in JP-A-3-174255, when the milling roll does not detect the rotational driving state due to a motor lock or the like, the energization to the motor of the rice milling apparatus may be cut off to stop the activation itself. is there.
[0005]
In such a case, Japanese Patent Application Laid-Open No. 7-124486 is transported to the raw material storage tank by the transport means, and is supplied to the raw material storage tank for a certain period of time before starting the rice milling apparatus. The conveying means is driven for the time until the whitening roll rotates. Accordingly, when the rice milling apparatus and the rice milling facility are stopped, the grains that have been put into the conveying path from the raw material charging unit to the rice milling apparatus remain.
[0006]
In JP-A-3-174255, the conveying means is activated simultaneously with the activation of the whitening roll, so that the grains enter the conveyance path while the whitening roll is restarted. Therefore, after the restart, if the rice milling facility is stopped due to overload or the like, the grains remain in the conveyance path in the same manner. At that time, the administrator of the rice milling facility must maintain the rice milling facility and take out the remaining grain at the same time, but since the grain remains in the entire transport route, it is necessary to remove all the input grain. It takes time and effort.
[0007]
In the present invention, when the rotational driving state of the whitening roll is not detected , the whitening roll is once started again after the whitening roll is stopped, and this is repeated a predetermined number of times. In the case of a rice milling facility that is configured to forcibly continue the milling roll when it is not detected, the transfer means is activated after the start of continuation of the activation so that the rice milling facility is stopped due to overload. It aims at further reducing the residual amount of the grain in the path | route of the conveyance means. And it aims at improving the ratio which can collect | recover the input grain from the raw material input part by these when an operator performs maintenance of a rice milling apparatus and a rice milling facility.
[0008]
[Means for Solving the Problems]
The present invention takes the following technical means in order to achieve the above-mentioned problems. In Claim 1, the raw material input hopper (5) which inputs a grain, the rotary valve (6) which conveys the grain in this raw material input hopper (5), and the grain discharged | emitted by the rotary valve (6) Elevator for stone removal device (7) for cerealing, stone removal machine (11) for removing stones in the grain cerealed by elevator (7) for stone removal device, and stone removal machine (11) Elevator for rice milling device (8) for milling extracted grain, rice milling device ( D ) for milling grain cerealed by elevator for rice milling device (8) with milling roll (15), and milling Whiteness selection buttons (34a), (34b), (34c) for setting the degree and starting the whitening work, and when the whiteness selection buttons (34a), (34b), (34c) are operated, the whitening roll (15) is configured to be activated, and the whitening roll (15) is activated to detect the rotational driving state. And detecting means (18b) detects the rotary valve (6), the stone disconnect device for elevator (7) and the rice apparatus for elevators (8) is configured to be activated,
When the detection means (18b) does not detect the rotational driving state of the whitening roll (15), the whitening roll (15) is once stopped and then again turned into the whitening roll (15). If the detection means (18b) does not detect the rotational driving state of the whitening roll (15) even after the predetermined number of times, the whitening roll (15) The rice milling facility is characterized in that the energization of the rotary valve (6), the lifting machine for stone removing device (7) and the lifting machine for rice milling device (8) are started .
[0009]
[0010]

[0019]
Next, the work process of the rice milling facility will be described with reference to FIGS. Grains (brown rice / mochi) as raw materials are put into the raw material charging hopper 2 (S100), and enough coins can be put into the coin mech 42 insertion slot (S101). Next, when the grain to be input is the rice cake, the rice cake selection button 33 is pressed (S102). When one of the whiteness selection buttons 44a, 44b, and 44c is selected and the whitening degree is set (S103), the whiteness adjustment motor 46 is activated to set the position of the compression plate 50. When these setting preparations are completed (S104), the CPU 40 reads the number of inserted coins (100-yen coins), calculates the operation time, outputs a drive signal over the calculation time, and each part of the apparatus starts operation (S105). ).
[0020]
The grains (brown rice / mochi) thrown into the raw material feeding hopper 2 are transported to the stone lifter elevator 7 by the rotary valve 6 and are raised by the bucket conveyor (not shown) of the stone lifter lift 7. The foreign matter removing device 10 of the stone removing device C is charged. Waste particles and the like are removed by the foreign material removing device 10 and supplied to the stone remover 11. The grains supplied to the stone remover 11 are subjected to rocking and sorting by the rocking and sorting plate 11a. Therefore, stones and the like mixed in the grains move to the upper side of the sorting plate, are discharged from the stone extraction outlet 60, and are stored in the storage chamber 61. On the other hand, the grain flows down to the side of the sorting plate and is supplied from the grain discharge port 11c to the elevator 8 for the rice milling apparatus.
[0021]
The grains that have been cerealed by the lift 8 for the rice milling apparatus are supplied to the rice milling apparatus D, and the surface cocoon layer is peeled off between the milling roll 15 and the milled platinum net 14 so as to achieve the set milling degree. The Then, the polished white rice is conveyed to the white rice tank 4 and can be collected in the operation chamber A as appropriate. Note that, during the whitening action by the whitening roll 15 and the whitening platinum net 14, the generated soot and the like are conveyed by air to the soot processing unit E, passed through the cyclone 21, and the soot transporting spout 23 is turned into a spiral (not shown). ) And collected in bag 24/24.
[0022]
When the time set by the input amount has elapsed for each part of operation (S106), first, the rotary valve 6 is stopped, and after a predetermined time, the stone removal device elevator 7, the stone removal device 11, the rice milling device elevator 8, Next, the rice milling device D and the like are stopped (S107), and the residual grain in the stone milling device elevator 7, the rice milling device elevator 8, and the rice milling device D can be reduced. Then, as a result of the rice milling work, if the input amount has not been reached, the coin withdrawal actuator 48 is actuated and the change is returned from the return port (not shown). Note that a prepaid card or the like may be used or used together as the whitening work starting means.
[0023]
Next, the drive sequence when starting the rice milling facility, which is the main part of the invention, will be described with reference to FIG. When the setting preparation is completed (S104), the milling roll 15 is activated by energizing the rice mill drive motor 45 (S110), and the rotation sensor 18b of the milling roll 15 detects the rotational drive state. (S111). Therefore, when the rotational drive state of the milling roll 15 is detected, the rotary valve 6, which is a conveying means, the lifting machine for stone removal device 7, and the lifting machine 8 for rice milling device are sequentially driven to transport the grains (S112).
[0024]
Thus, by starting the whitening roll before the conveying means, the detection of the rotational driving or non-rotating driving state of the whitening roll is performed before the starting of the conveying means. At this time, when the rice milling facility is stopped due to an abnormality such as overload, the amount of grain remaining in the conveying means can be reduced. In this case, the milling roll 15 does not detect the rotational drive state due to overload or the like. In this case, the rotary valve 6, the stone elevating machine elevator 7, and the rice milling machine elevator 8 are activated. (S113)
[0025]
By adopting such a configuration, when the rice milling apparatus D is stopped, the grain does not remain in the rotary valve 6, the stone elevating machine lifting machine 7, and the rice milling machine lifting machine 8. On the other hand, when the milling roll 15 is first activated, the milling roll 15 is not activated, but once the milling roll 15 is stopped, the milling roll 15 is activated again and the milling roll 15 is rotated. A rice milling facility configured to forcibly continue the milling roll 15 when the driving state is detected, for example, is repeated twice, and the rotational driving state is still not detected, with reference to FIG. When the milling roll 15 is first activated (S120), the rotational drive state of the milling roll 15 is detected (S121). At that time, if the rotational state of the milling roll 15 cannot be detected, the milling roll 15 is once stopped (S122) and then the milling roll 15 is started again (S123). Is detected (S124). At this time, until the rotational drive of the milling roll 15 is detected, the rotary valve 6, the stone lifter lifting machine 7, and the rice milling machine lifter 8 are not started. If the rotational drive is not detected, the rotary valve 6, the stone elevating machine elevator 7 and the rice milling machine elevator 8 are activated after the third forced start of the milling roll (S125), for example. Start (S126). When the milling roll is forcibly continued and the milling facility is stopped due to an abnormality such as overload (S127), the milling operation is completed.
[0026]
The above-mentioned rice milling facility means that it is not necessary to stop the rice milling facility as much as possible for the workers who use the rice milling facility, and if the milling roll is forcibly continued, the milling roll will be driven to rotate. However, when the milling roll is restarted, the rotary valve 6, the stone lifter lifting machine 7, and the rice milling machine lifter 8 are used for the grains. Since the grains are not conveyed, the residual amount of grains can be further reduced when the rice milling facility is stopped due to an abnormality such as overload immediately after the start of the milling roll is forcibly continued.
[0027]
From the above, according to the present invention, when the rice milling facility is stopped, it is possible to improve the rate at which the input grain can be recovered from the raw material input unit when the administrator performs maintenance.
