Description

【0001】
【発明の属する技術分野】
本発明は、玄米等の穀類を精白する精米機に関し、特に、搗精品質を確保した上で、精白処理後に穀類が機体内に残留することなく迅速に排出することができる簡易な構成の精米機に関する。
【0002】
【従来の技術】
【特許文献1】
特開平7−132239号公報
従来、投入ホッパから供給口に受けた玄米を圧送搗精する前下がり配置の搗精部、搗精部の精白圧力を確保する抵抗板、除糠送風機等を備えた精米機が知られている。この精米機は、精白処理が進んで投入ホッパの玄米が尽きると搗精部の圧送力が減少し、また、除糠送風機の吸着作用等により、投入米の一部残留が避けられないので、この残留米が次の精白処理に混入したり、次の精白処理まで長時間滞留することにより品質問題の原因となっていた。特に、コイン式自動精米機においては、銘柄等級の不明な先行者による残留米が混入することによる違和感や異種銘柄米の混入による食味の低下等の問題を抱えていた。
【0003】
この問題に対して、特許文献1の精米機が提案されている。この精米機は、搗精部の排出口側を低く傾斜配置し、供給口に設けた米検出センサにより、ホッパの玄米が尽きた後に除糠送風機を停止し、抵抗板を開放したままさらに搗精部を継続稼動することにより、複雑な構成を要することなく、搗精部の傾斜により残留米を最後まで排出するように運転制御して上記問題の解決を図ったものである。
【0004】
【発明が解決しようとする課題】
しかしながら、上記構成の精米機は、搗精部を継続稼動してその搗精ロールの送り作用によって内部の残留米を排出するものであることから、全残留米を排出するまでに多くの時間を要するとともに、傾斜した搗精部内の前後位置の圧力差によって精白処理の仕上がりに悪影響を与えるので、搗精品質の面から傾斜角度を小さく抑えざるを得なかった。したがって、排出終了までの利用者の待ち時間の増加とともに精米機の占有時間の増加による利用回転率の低下を招くこととなる。
【0005】
本発明の目的は、簡易な構成により、搗精品質を確保した上で、精白処理後に穀類を機体内に残留することなく迅速に排出することができる精米機を提供することにある。
【0006】
【課題を解決するための手段】
上記課題を解決するために、請求項1に係る発明は、類を供給口から受けて搗精ロールにより精白処理する搗精部と、この搗精部の排出口抵抗を与える開閉可能な抵抗板とを備える精米機において、上記搗精部には、その供給口の投入側を閉鎖可能なシャッタを備え、搗精部の供給口に、供給口送風路を介して送風機を連結すると共に、穀類が無いことを検出するセンサを設け、さらに、上記センサの検出信号により、シャッタの閉鎖、抵抗板の開放および供給口送風路への送風を行うことを特徴とする。
【0007】
穀類の投入が尽きるとこれをセンサが検出し、抵抗板を開放するとともにシャッタを閉じ、さらに供給口送風路により搗精部の供給口に送風するべく稼動制御すると、供給口の投入側がシャッタで閉鎖されていることから、供給口送風路による送風空気は搗精部の内部を通って排出口から流出し、この空気流とともに搗精部の内部に残留した穀類が排出される。
【0008】
請求項2に係る発明は、前記搗精部には除糠用の通風手段を設け、この通風手段 類が無いことを検出するセンサの検出信号により前記抵抗板の開放、シャッタの閉鎖、供給口送風路への送風の動と連動して通風を停止することを特徴とする。この精米機は、除糠通風手段により除糠下で搗精する場合において、同通風手段を停止するべく稼動制御することにより、搗精部の除糠網等に通風圧力によって残留した穀類が吸着されること無く、排出送風によって能率良く排出口から排出される
0009
【発明の効果】
本発明の精米機は以下の効果を奏する。
上記精米機は、所定の稼動制御により、搗精部の供給口から排出口に向かう空気流とともに搗精部の内部に残留した穀類が排出されることから、搗精部に特段の構成変更を要することなく、搗精部の供給口に送風手段を付加しただけの簡易な構成により、搗精品質を確保した上で、利用者の待ち時間の増加を抑え、精米機の占有時間の増加による利用回転率の低下を招くことなく、内部に残留した穀類を搗精部から迅速に排出することができる。
0010
除糠通風手段が連動して停止するように構成した場合は、搗精部の除糠網等に通風圧力によって残留した穀類が吸着されること無く、供給口送風によって能率良く排出口から残留した穀類が排出されるので、通風手段による除糠機能を確保した上で、搗精部から残留した穀類を迅速に排出することができる。
0011
センサの検出信号により精白処理の終了とともに残留物の排出動作を稼動制御する場合は、精白処理の都度、確実に残留物が排出されることから、コイン式の自動精米機等において、利用者の待ち時間の増加および利用回転率の低下を招くこととなく、先行処理物の混入による違和感や処理品質の問題を解決することができる。
0012
【発明の実施の形態】
上記技術思想に基づき具体的に構成された実施の形態について以下に図面を参照しつつ説明する。本発明の精米機1は、図1の縦断側面図に示すように、投入ホッパ2aによる投入部2、回転する搗精ロール3aを備えて玄米を精白処理する搗精部3、電動機4等を収容した補機部5により構成される。
0013
投入ホッパ2aは投入玄米を受けてその下端から搗精部3の供給口3bに案内するべく連通接続する。搗精ロール3aは、通風路をなす中空軸に螺旋部3cと通風用のスリット3dとを備え、供給口3bから受けた玄米を回転動作により排出口3e方向に送り出すとともに中空部からの通風により精白米を除糠する。
0014
搗精部3の供給口3bには、投入ホッパ2aからの玄米供給が無くなったことを検出するセンサ10と投入ホッパ2aの下端を閉じるシャッタ11を設けるとともに供給口送風路13を連通する。シャッタ11はセンサ10が無米状態を検出すると投入ホッパ2aとの間を閉鎖するように制御されるソレノイド12等のアクチュエータにより開閉動作可能に構成する。また、搗精部3には、精白処理による糠を吸引除去する除糠網14による除糠部とシュータ付き排出口3eを押さえて搗精圧を加える抵抗板15とその圧力を開閉調節するアクチュエータ16とを備える。除糠部には、除糠網14に臨む吸引管14aとその吸引用の除糠送風機17を設ける。
0015
動力伝動系については、電動機4からベルト伝動を受けるプーリ21を搗精ロール3aに設けるとともに、この動力を分岐するプーリ22を近接配置して除糠送風機17にベルト伝動する。供給口3bの供給口送風路13には、別の電動式の供給口送風機18を配設する。上記各機器は、図示せぬ制御部によって精白処理、残留物排出処理等に応じて協調動作可能にそれぞれを制御する。
0016
上記構成の精米機1による精白処理は、投入ホッパ2aに投入された玄米(精白物)が供給口3bから搗精部3に進入し、搗精ロール3aの送り作用と抵抗板15とによる搗精圧によって精白処理を行いこの精白米は、除糠部の通風によって吸引除糠される。精白処理が進行して投入ホッパ2aの玄米が尽きると、センサ10の信号によって残留物の排出処理に移行する。
0017
この残留物の排出処理は、作用説明のための搗精部の拡大断面図を図2に示すように、センサ10が供給口3bの無米状態を検出すると、図示せぬ制御部により図例では搗精部3の停止を介して除糠送風機17を停止し、抵抗板15の開放、シャッタ11の閉鎖をした上で、供給口送風機18を稼動して供給口送風路13から送風を行うように稼動制御する。この送風により、供給口3bから排出口3eに空気が抜け、この空気流とともに、除糠網14に吸着されること無く、搗精部3から残留した穀類が排出される。
0018
したがって、上記構成の精米機1は、簡易な構成により、利用者の待ち時間の増加を抑え、精米機1の占有時間の増加による利用回転率の低下を招くことなく、内部に残留した穀類を搗精部3から迅速に排出することができるので、先行処理物の混入による違和感や処理品質の問題を解決することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a rice milling machine for whitening grains such as brown rice, and in particular, a rice milling machine having a simple configuration capable of quickly discharging grain without remaining in the machine body after the milling process while ensuring milling quality. About.
[0002]
[Prior art]
[Patent Document 1]
JP, 7-132239, A Conventionally, the rice milling machine provided with the milling part of the front-lowering arrangement which pressure-feeds and refines the brown rice which received from the input hopper to the supply mouth, the resistance board which secures the whitening pressure of the milling part, the de-airing blower, etc. Are known. In this rice milling machine, when the whitening process proceeds and the brown rice in the input hopper is exhausted, the pumping power of the milling section decreases, and the remaining part of the input rice is unavoidable due to the adsorption action of the demolding blower, etc. Residual rice was mixed into the next whitening treatment or stayed for a long time until the next whitening treatment, causing quality problems. In particular, the coin-type automatic rice milling machine has problems such as a sense of incongruity due to the mixing of residual rice by an antecedent whose brand grade is unknown, and a decrease in taste due to mixing of different brands of rice.
[0003]
For this problem, a rice milling machine disclosed in Patent Document 1 has been proposed. This rice milling machine has a low-tilt discharge outlet side of the milling section, and the rice detection sensor provided at the feeding port stops the dehuller blower after the brown rice in the hopper is exhausted, and the milling section is further opened with the resistance plate open. By continuing the operation, the above-mentioned problem is solved by controlling the operation so that the remaining rice is discharged to the end by the inclination of the milling portion without requiring a complicated configuration.
[0004]
[Problems to be solved by the invention]
However, since the rice milling machine having the above configuration continuously operates the milling unit and discharges the residual rice inside by the feeding action of the milling roll, it takes a lot of time to discharge all the residual rice. Since the finish of the whitening process is adversely affected by the pressure difference between the front and rear positions in the tilted spermatozoon, the tilt angle has to be kept small in terms of sperm quality. Therefore, the increase in the waiting time of the user until the end of the discharge and a decrease in the utilization rate due to the increase in the occupation time of the rice milling machine are caused.
[0005]
An object of the present invention is to provide a rice mill capable of promptly discharging cereals without remaining in the machine body after the milling process while ensuring milling quality with a simple configuration.
[0006]
[Means for Solving the Problems]
In order to solve the above problems, the invention according to claim 1, a pearling unit for milling process by pearling roll receives cereals from the feed opening, and an openable resistive plate giving the outlet resistance of the pearling portion In the rice milling machine, the milling unit is provided with a shutter that can close the inlet side of the supply port, and the blower is connected to the supply port of the milling unit via the supply port air passage and has no grains. a sensor for detecting provided, further, the detection signal of the sensor, closed chain of the shutter, and performs sending wind to the open- Contact and supply port air flow passage of the resistive plate.
[0007]
When the input of cereals is exhausted, the sensor detects this, opens the resistance plate, closes the shutter, and further controls the operation to send air to the supply port of the milling section through the supply port air passage, closing the supply port input side with the shutter Therefore, the air blown by the supply port air flow path flows out from the discharge port through the inside of the finer portion, and the cereal remaining in the finer portion is discharged together with this air flow.
[0008]
The invention according to claim 2, said pearling portion provided ventilation means for removing bran, the ventilation means, the opening of the resistive plate by a detection signal of a sensor which detects that cereals no closure of the shutter, in conjunction with the operation of the blower to supply port airflow path, characterized in that stop ventilation. In this rice milling machine, when the rice is milled under the removal by the removal air ventilation means, the remaining grains are adsorbed by the removal pressure of the removal net or the like of the polishing portion by controlling the operation to stop the ventilation means. Without being exhausted, it is efficiently discharged from the outlet by the exhaust air .
[ 0009 ]
【The invention's effect】
The rice mill of the present invention has the following effects.
In the above rice milling machine, the cereals remaining in the milling unit are discharged together with the air flow from the supply port to the discharge port of the milling unit by a predetermined operation control, so that no special configuration change is required in the milling unit. , By simply adding air blowing means to the feeding port of the milling unit, the milling quality is ensured, the waiting time of the user is suppressed, and the rotation rate of the milling machine is reduced due to the increase in the occupied time of the rice milling machine. The grain remaining inside can be quickly discharged from the scouring part without incurring any other problem.
[ 0010 ]
When it is configured so that the air removal means is stopped in conjunction with it, the cereals remaining from the discharge port efficiently by the supply port air blowing without adsorbing the cereals remaining due to the ventilation pressure on the dewatering net etc. Therefore, it is possible to quickly discharge the cereals remaining from the milled portion while ensuring the function of removing the debris by the ventilation means.
[ 0011 ]
When the operation of controlling the residue discharge operation at the end of the whitening process based on the detection signal of the sensor, the residue is reliably discharged every time the whitening process is performed. Without causing an increase in waiting time and a decrease in utilization rate, it is possible to solve problems of discomfort and processing quality due to the mixing of the preceding processed products.
[ 0012 ]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments specifically configured based on the above technical idea will be described below with reference to the drawings. As shown in the longitudinal side view of FIG. 1, the rice mill 1 of the present invention accommodates a milling unit 3 that is equipped with a feeding unit 2 by a feeding hopper 2 a, a rotating milling roll 3 a and whitening brown rice, an electric motor 4, and the like. The auxiliary unit 5 is configured.

The milling roll 3a is provided with a spiral portion 3c and a slit 3d for ventilation on a hollow shaft that forms a ventilation path, and sends out brown rice received from the supply port 3b in the direction of the discharge port 3e by a rotating operation and is also refined by ventilation from the hollow portion. Remove white rice.
[ 0014 ]
The supply port 3b of the milling unit 3 is provided with a sensor 10 for detecting that the supply of brown rice from the input hopper 2a is lost, and a shutter 11 for closing the lower end of the input hopper 2a, and communicates with the supply port air passage 13. The shutter 11 is configured to be openable and closable by an actuator such as a solenoid 12 that is controlled so as to close between the closing hopper 2a when the sensor 10 detects a state of no rice. Further, the finer portion 3 includes a debris portion by a debris net 14 that sucks and removes the fine particles due to the whitening process, a resistance plate 15 that applies the fine pressure by pressing the discharge port 3e with the shooter, and an actuator 16 that adjusts the opening and closing of the pressure plate. Is provided. In the removal part, a suction pipe 14a facing the removal net 14 and a removal fan 17 for suction are provided.
[ 0015 ]
As for the power transmission system, a pulley 21 that receives belt transmission from the electric motor 4 is provided on the fine roll 3 a, and a pulley 22 that branches this power is disposed close to the belt to be transmitted to the fanning blower 17. Another electric supply port blower 18 is disposed in the supply port air passage 13 of the supply port 3b. Each of the above devices is controlled by a control unit (not shown) so as to be capable of cooperative operation in accordance with a whitening process, a residue discharge process, and the like.
[ 0016 ]
In the milling process by the rice mill 1 having the above-described configuration, the brown rice (milled product) fed into the feeding hopper 2 a enters the milling unit 3 from the supply port 3 b, and is fed by the milling pressure by the milling roll 3 a feeding action and the resistance plate 15. After the whitening process, the polished rice is sucked and removed by the ventilation of the removal part. When the whitening process proceeds and the brown rice in the input hopper 2a is exhausted, the process proceeds to a residue discharge process by a signal from the sensor 10.
[ 0017 ]
