粉砕機の運転制御システムおよび診断装置Crusher operation control system and diagnostic device

　図１０、図１１の石臼式粉砕機に示すように粉砕機１は、中央に供給ホッパー２を取り付けた上蓋５の下方にグラインダー本体３を設けている。
　グラインダー本体３は重圧摩砕砥石を使用するもので、上蓋５に下向きに外周部に摩砕平坦面を有し、該平坦面に連続して内側に中くぼみ状の円錐台形部を形成したリング状固定砥石６を固定し、該固定砥石６に対向して上向きに摩砕平坦面を有し、同じく中くぼみ状の円錐台形部を形成した回転砥石７を原動機８で回転駆動する駆動軸９に固定した。図中１０は被摩砕物質取り出し用のダクトである。
　そして、上方の供給ホッパー２から装入された被摩砕物質はリング状固定砥石６及び回転砥石７の双方の圧接部分で極微粒子に摩砕され取り出し用のダクト１０から出てくる。
　リング状固定砥石６に対して回転砥石７は昇降可能に設けられ、この昇降はサーボモータ１１か、手動調整ハンドル１２で駆動される。
　図１２はこの昇降機構の詳細を示したもので、サーボモータ１１は、サーボモータ取付フランジ１３により本体装置に取り付き、ユニバーサルジョイント１４を介してユニバーサルジョイント用ウォームシャフト１５が接続される。このユニバーサルジョイント用ウォームシャフト１５にはキー１６を介してウォームギヤ１７が設置され、これがヘリカルギヤ１８に噛合する。
　図１３に示すように、ヘリカルギヤ１８は回転砥石７の昇降軸であるアジャスト１９を回転させる歯車で、前記サーボモータ１１の回転はウォームギヤ１７→、ヘリカルギヤ１８→アジャスト１９に伝達タされ、アジャスト１９が左右に回転することで回転砥石７はリング状固定砥石６に対して昇降し、回転砥石７とリング状固定砥石６間のクリアランスが変化する。
　手動調整ハンドル１２はユニバーサルジョイント用ウォームシャフト１５の前記サーボモータ１１とは反対側に設けられ、ユニバーサルジョイント用ウォームシャフト１５のこの手動調整ハンドル１２の取付部分はエンドサポート２０で機体に取り付く球面ブッシュケース２１内の球面ブッシュ２２で回転自在に支承される。図中２３はウォームクランプである。
　また、サーボモータ１１による機器の破損を防ぐものとして、フォトセンサー３１ａ（上限）、３１ｂ（下限）をケーシング内に設ける。
　そして、上方の供給ホッパー２から装入された被摩砕物質はリング状固定砥石６及び回転砥石７の双方の圧接部分で極微粒子に摩砕され取り出し用のダクト１０から出てくる。
　このように極微粒子に摩砕することによって味覚並びに歩留を良好ならしめる製飴、スープ、ジュース等の食品が得られる。また、顔料塗料等の工業品等にこの砥石を用いてもよい。
　前記石臼式粉砕機は一定の粒径の超微粒子を連続して、かつ安定して得られなければならない。従って、上下の砥石の摩砕平坦面間のクリアランスは極めて重要であるが、従来は始動前に人手によってクリアランスを設定しており、これでは原料や必要粒度により常にクリアランスを一定にしておくことはできなかった。
　さらに、原料を粉砕することで砥石表面が摩耗するため初期のクリアランスが変化してしまい、この状態で連続運転を続けた場合、製品中に所望の粒径より大きい粗い粒子が混入し、品質の安定した製品が得られないこともある。
　そこで従来は一定時間毎に人手によりクリアランス調整が必要となり、多数台を同時に運転した場合や自動化ラインを構成した場合には特に大変な作業となっていた。
　また、原料の温度や粉砕時の摩擦により発生する熱のため機械本体及び砥石が熱膨張してクリアランスが狭くなってしまい、この状態が長時間続いた場合は砥石同志の強い摩擦が連続するので摩砕面の異常摩耗や過負荷のため機械の故障の原因となっていた。
　さらに砥石の膨張が安定するには時間が必要であるため、この間やはり人手により少しずつクリアランスの調整が必要であり作業者にとって大きな負担となっていた。
　下記特許文献は摩砕平坦面間の微小なクリアランスを自動的に調整することのできる装置として提案されたものである。

A worm gear 17 is installed on the universal joint worm shaft 15 via a key 16 and meshes with the helical gear 18.
As shown in FIG. 13, the helical gear 18 is a gear for rotating the adjust 19 which is the elevating shaft of the rotary grindstone 7. The rotation of the servomotor 11 is transmitted from the worm gear 17 → helical gear 18 → adjust 19. By rotating left and right, the rotary grindstone 7 is moved up and down with respect to the ring-shaped fixed grindstone 6, and the clearance between the rotary grindstone 7 and the ring-shaped fixed grindstone 6 changes.
The manual adjustment handle 12 is provided on the side opposite to the servomotor 11 of the universal joint worm shaft 15, and the mounting portion of the manual adjustment handle 12 of the universal joint worm shaft 15 is a spherical bush case attached to the body by the end support 20. The bearing 21 is rotatably supported by a spherical bush 22 in the housing 21. In the figure, 23 is a worm clamp.
Moreover, as a thing to prevent the damage of the apparatus by the servomotor 11, the photosensors 31a (upper limit) and 31b (lower limit) are provided in a casing.
Then, the material to be ground charged from the upper feed hopper 2 is ground to ultrafine particles at the pressure contact portions of both the ring-shaped fixed grindstone 6 and the rotary grindstone 7 and comes out from the duct 10 for removal.
By grinding into extremely fine particles in this manner, food products such as rice bran, soup, juice and the like which can improve taste and yield can be obtained. In addition, the grindstone may be used for industrial products such as pigment paint.
The above-described mill must be able to continuously and stably obtain ultrafine particles of a certain particle size. Therefore, although the clearance between the grinding flat surfaces of the upper and lower grinding wheels is extremely important, conventionally, the clearance is manually set before starting, and in this case it is always possible to keep the clearance constant depending on the raw material and the required particle size. could not.
Furthermore, crushing the raw material causes wear on the surface of the grinding wheel, which changes the initial clearance, and when continuous operation is continued in this state, coarse particles larger than the desired particle diameter are mixed in the product, resulting in quality deterioration Sometimes a stable product can not be obtained.
Therefore, conventionally, it is necessary to manually adjust the clearance at regular time intervals, and it has been particularly difficult when a large number of machines are operated at the same time or when an automation line is configured.
In addition, the heat generated by the temperature of the raw material and friction during grinding causes thermal expansion of the machine body and the grinding wheel to narrow the clearance, and if this state continues for a long time, the strong friction between the grinding wheels will continue. It was the cause of machine failure due to abnormal wear and overload on the grinding surface.
Furthermore, since it takes time to stabilize the expansion of the grinding wheel, it is also necessary to adjust the clearance little by little by hand during this time, which is a heavy burden on the operator.
The following patent documents are proposed as an apparatus capable of automatically adjusting the minute clearance between the grinding flat surfaces.
Japanese Patent Publication No. 3-51464
　前記特許文献２は、回転砥石を回転駆動する主モータの負荷に対応する入力電流の変化を直流電圧に変換する変換器と、この直流電圧の基準電圧からの偏差に応じて上記駆動機器を動作させ、回転砥石と固定砥石とのクリアランスを調整する制御機器とを設けてなる。
　この特許文献２によれば、摩砕機において回転砥石を上下動する手動の調整ハンドルに代えてサーボモータを用いて回転砥石を上下動させる構成とし、さらに回転砥石を回転駆動する主モータの負荷を常時検出し、この大小によりサーボモータを正又は逆回転させてクリアランスを所定の値に保つ。 The patent document 2 operates the drive device according to a converter that converts a change in input current corresponding to the load of a main motor that rotationally drives the rotary grindstone into a DC voltage, and a deviation of the DC voltage from a reference voltage. And a control device for adjusting the clearance between the rotary grindstone and the fixed grindstone.
According to this patent document 2, in place of the manual adjustment handle for moving the rotary grindstone up and down in the grinding machine, a servomotor is used to move the rotary grindstone up and down, and further the load of the main motor for rotationally driving the rotary grindstone It is always detected, and the servomotor is rotated forward or backward according to the magnitude to keep the clearance at a predetermined value.
　前記特許文献２の方法では、下部の回転砥石を回転させた後該回転砥石を上昇させて上部の固定砥石と接触させたときの主モータの負荷の変化で異常を検知することになる。
　上下砥石間のクリアランスがゼロの基準状態を設定するべく砥石間に水を投入して、下部の回転砥石を回転させた後該回転砥石を上昇させて上部の固定砥石と接触させたときの主モータの負荷の変化は、上下の両砥石を強く接触させた場合でも７ｋＷ程度であり、これに対して同じ摩砕機で実際に樹脂を粉砕した場合の負荷の変化は２ｋＷ~２０ｋＷまでランダムに変化しており、上記のクリアランスのゼロ状態を主モータの負荷信号で検出するのは非常に困難であった。
　このような問題を解決しようとして特開平８−１０２０号公報では、サーボモータを備えた摩砕機の運転時に該サーボモータを駆動して下部回転砥石を上昇させて上記摩砕平坦面間のクリアランスをゼロとし、その時のサーボモータのトルク信号により該サーボモータを停止した後直ちに下部回転砥石を所定クリアランスまで下降させる動作を断続的に複数回繰り返すこととしている。
　サーボモータは回転砥石を上下動させるための駆動源であるが、そのトルク制御機能によれば該サーボモータの出力軸に加わるトルクが予め設定されたトルク値となった時に、該サーボモータを停止してその位置をクリアランスがゼロと定め、このクリアランスがゼロ位置から該サーボモータを逆回転して所定のクリアランスとなるまで回転砥石を下降させることで、所望のクリアランスが得られるというものである。
　しかし、この方法では機械本体や砥石の熱膨脹によるクリアランスの変化や原料の粉砕摩砕による砥石表面の摩耗によるクリアランスの変化に対しては、上記のような動作を頻繁に行なう必要があり、特に運転開始直後の約３０分間は特に砥石の膨脹によるクリアランスの変化が大きいため上記動作を繰り返す時間間隔は短くしなければならない。
　特に粉砕摩砕を行う原料に対して砥石を接触し続けてクリアランスの状態を判断することはできず、摩砕平坦面間のクリアランスをゼロとした時点でサーボモータを停止した後直ちに下部回転砥石を所定クリアランスまで下降させる動作を断続的に複数回繰り返すことを行わなければならない。
　すなわち、上記のような動作を頻繁に行なわなければ、機械本体や砥石の熱膨脹によるクリアランスの変化や原料の粉砕摩砕による砥石表面の摩耗によるクリアランスの変化に対して常にクリアランスは所定の値に保つことができない。
　従来、粉砕を行う食材または材料に対する固定砥石と回転砥石との適正クリアランス判断は回転砥石を動かしてみてその時の音により判断することもおこなわれていた。しかし、食材または材料の種類で音の状態はそれぞれ異なり、その判断に経験を必要とし、高度な技術を保有する熟練技能者だけが行えるものでありまた、周囲の雑音等で聴取が困難となる。
　本発明の目的は前記従来例の不都合を解消し、第１に、負荷の変化という不安定要因ではなく、また、音を聞いての人の判断でもなく、振動センサーの反応で接触状態の適否を判定することにより、確実な判定が迅速に得られ、高度な技術を保有する熟練技能者がなくても、高度な加工を行うことができ、加工の難しかった食品の加工も可能になる粉砕機の運転制御システムを提供することにある。
　第２に、運転状況をデジタル表示し安定した運転の補助に利用することができ、また、砥石のクリアランス等の調整が可能なので作製する品質の安定を確保でき、さらに、軸受け・モータの異常を検知し故障判断を行うことや、砥石および刃物の重心ずれなどの良否判定を行うことが簡単にでき、また、品質管理として利用することもできる粉砕機の診断装置を提供することにある。 In the method of Patent Document 2, after rotating the lower rotary grindstone, the rotary grindstone is raised to detect an abnormality based on a change in load of the main motor when it contacts the upper fixed grindstone.
Water is poured between the grinding wheels to set a reference state where the clearance between the upper and lower grinding wheels is zero, the lower rotating grinding wheel is rotated and then the rotating grinding wheel is raised to contact with the upper fixed grinding wheel The change in motor load is about 7 kW even when the upper and lower wheels are in strong contact, while the change in load when resin is actually crushed by the same grinder changes randomly from 2 kW to 20 kW It is very difficult to detect the above-mentioned clearance zero state by the load signal of the main motor.
In order to solve such a problem, in JP-A-8-1020, during operation of a grinding machine equipped with a servomotor, the servomotor is driven to raise the lower rotary grindstone to increase the clearance between the above-mentioned grinding flat surfaces. The operation of lowering the lower rotary grinding stone to a predetermined clearance immediately after stopping the servomotor by a torque signal of the servomotor at that time is intermittently repeated a plurality of times.
The servomotor is a drive source for moving the rotary grindstone up and down. According to its torque control function, the servomotor is stopped when the torque applied to the output shaft of the servomotor reaches a preset torque value. Then, by setting the clearance as zero and setting the clearance back to zero from the zero position until the predetermined clearance is reached, the desired clearance can be obtained.
However, with this method, it is necessary to frequently perform the above operation against changes in the clearance due to thermal expansion of the machine main body and the grinding wheel and changes in the clearance due to abrasion of the grinding wheel surface due to grinding and crushing of raw materials. The time interval for repeating the above operation should be short, especially for about 30 minutes immediately after the start, because the change in the clearance due to the expansion of the grinding wheel is large.
In particular, it is not possible to judge the state of the clearance by continuing the contact of the grindstone with the raw material to be crushed and ground, and it is not possible to judge the state of the clearance. The operation of lowering the distance to the predetermined clearance must be repeated several times intermittently.
That is, if the above operation is not performed frequently, the clearance is always kept at a predetermined value against the change of the clearance due to the thermal expansion of the machine main body or the grinding wheel or the change of the clearance due to the wear of the grinding wheel surface due to the grinding of raw materials. I can not do it.
Heretofore, it has been practiced to determine the proper clearance between the fixed grindstone and the rotary grindstone with respect to the material or material to be crushed by moving the rotary grindstone and judging by the sound at that time. However, the state of the sound differs depending on the type of food or material, and it requires experience to make such judgments, and only skilled technicians who possess advanced technology can do it. .
The object of the present invention is to eliminate the disadvantages of the prior art, and firstly, it is not an unstable factor such as a change in load, nor a person's judgment of hearing a sound, but the appropriateness of the contact state by the reaction of the vibration sensor. It is possible to obtain a reliable judgment quickly by judging the smashing, allowing high-level processing without requiring skilled technicians who possess high-level technology, and also possible processing of food which has been difficult to process. To provide an operation control system for the aircraft.
Second, it can be used to digitally display the operating conditions and assist in stable operation, and since the adjustment of the wheel clearance and the like is possible, it is possible to ensure stable quality to be produced, and furthermore, bearing / motor abnormalities It is an object of the present invention to provide a crusher diagnostic device which can be easily detected and judged as a failure, and judgment of quality such as deviation of the center of gravity of a grinding stone and a blade can be easily performed, and can also be used as quality control.

In a millstone crusher equipped with a servomotor for vertically moving a rotary grindstone, in which a ring-shaped fixed grindstone forming a portion and a ring-shaped rotary grindstone are vertically disposed with their grinding flat surfaces facing each other. An object of the present invention is to provide a vibration sensor on the machine body and to control the movement of the rotary grinding stone based on the reaction of the vibration sensor.
The inventor noted that when the clearance of the upper and lower grinding wheels and the flat surface of the grinding changes, the vibration also changes, so that the optimum clearance can be set by digitizing this based on the vibration instead of the sound. According to the present invention as set forth in claim 1, it is possible to set an appropriate clearance without using human sensitivity as a judgment factor by controlling the movement of the rotating grinding stone based on the reaction of the vibration sensor. it can.
As the movement continues, the parts expand and the grinding wheels are strongly pressed against each other, and the temperature of the raw material rises and burns, which requires adjustment. In the past, it was difficult for the adjustment to be done by sounds and smells, and not by delicate and experienced skilled technicians.
According to the first aspect of the present invention, since a slight thermal expansion can also be grasped as an increase in numerical value by the vibration sensor, it is possible to always maintain a constant pressure contact state.
According to the second aspect of the present invention, while rotating the rotary grindstone, it is moved to the fixed grindstone side to be in contact with the food material or material to be ground, and when it contacts, the vibration sensor detects the presence or absence of vibration and The gist of the present invention is to control the movement of the rotary grindstone based on the above.
In the present invention, the movement of the rotary grindstone is controlled by comparing the stored proper vibration value and the vibration sensor to be actually measured. According to the present invention of claim 2, the desired set value is Since it changes depending on the type and conditions of the raw material and the grinding wheel, the vibration value can be determined in advance by the fineness, temperature and state of the raw material which has been manually operated and processed in advance.

The gist of the present invention is that it comprises an auxiliary device for setting an EP (Easy Point).
According to the present invention as set forth in claim 4, a stable clearance can be maintained by digitizing the vibration value with respect to the clearance of the grinding wheel by the vibration sensor. The clearance changes at any time due to thermal expansion or abrasive wear. Until now, I had judged by my sense. By quantifying the vibration value, even an unskilled person can accurately set the clearance.
The vibration sensor detects abnormalities in bearings and motors to make a fault judgment. Currently, it was judged by the abnormal sound and vibration due to the sound or the touch of the hand. The vibration sensor can accurately quantify the vibration, so the bearing and motor life can be clearly determined.
The vibration sensor is used to digitally display the deviation of the center of gravity of the grinding wheel and the blade to judge whether the wheel is good or bad. Whether the center of gravity shift is within an acceptable range or a defect can be accurately determined by using the change in magnitude of vibration between when the wheel is not attached and when the wheel is attached.
Furthermore, the vibration value can be recorded simultaneously with the elapsed time and used as quality control. The vibration value is a standard for keeping the clearance of the grinding wheel constant. Therefore, if the vibration value is adjusted to be constant, the quality can be stabilized.

　以下、図面について本発明の実施の形態を詳細に説明する。図１は本発明の運転制御システムおよび診断装置を備えた石臼式粉砕機の要部の斜視図で、本発明の診断装置は振動センサー２７と振動センサー２７が砥石の振動を捉え数値化することによって接触状態もしくはクリアランスを適正にたもつＥＰ（イージーポイント）を設定する補助機器とからなる。
　図１０、図１１に示すように、粉砕機１は、中央に供給ホッパー２を取り付けた上蓋５の下方にグラインダー本体３を設けている。
　グラインダー本体３は重圧摩砕砥石を使用するもので、上蓋５に下向きに外周部に摩砕平坦面を有し、該平坦面に連続して内側に中くぼみ状の円錐台形部を形成したリング状固定砥石６を固定し、該固定砥石６に対向して上向きに摩砕平坦面を有し、同じく中くぼみ状の円錐台形部を形成した回転砥石７を原動機８で回転駆動する駆動軸９に固定した。図中１０は被摩砕物質取り出し用のダクトである。
　そして、上方の供給ホッパー２から装入された被摩砕物質はリング状固定砥石６及び回転砥石７の双方の圧接部分で極微粒子に摩砕され取り出し用のダクト１０から出てくる。
　リング状固定砥石６に対して回転砥石７は昇降可能に設けられ、この昇降はサーボモータ１１か、手動調整ハンドル１２で駆動される。
　図１２はこの昇降機構の詳細を示したもので、サーボモータ１１は、サーボモータ取付フランジ１３により本体装置に取り付き、ユニバーサルジョイント１４を介してユニバーサルジョイント用ウォームシャフト１５が接続される。このユニバーサルジョイント用ウォームシャフト１５にはキー１６を介してウォームギヤ１７が設置され、これがヘリカルギヤ１８に噛合する。
　図１３に示すように、ヘリカルギヤ１８は回転砥石７の昇降軸であるアジャスト１９を回転させる歯車で、前記サーボモータ１１の回転はウォームギヤ１７→ヘリカルギヤ１８→アジャスト１９に伝達され、アジャスト１９が左右に回転することで回転砥石７はリング状固定砥石６に対して昇降し、回転砥石７とリング状固定砥石６間のクリアランスが変化する。
　手動調整ハンドル１２はユニバーサルジョイント用ウォームシャフト１５の前記サーボモータ１１とは反対側に設けられ、ユニバーサルジョイント用ウォームシャフト１５のこの手動調整ハンドル１２の取付部分はエンドサポート２０で機体に取り付く球面ブッシュケース２１内の球面ブッシュ２２で回転自在に支承される。図中２３はウォームクランプである。
　また、サーボモータ１１による機器の破損を防ぐものとして、フォトセンサー３１ａ（上限）、３１ｂ（下限）をケーシング内に設ける。
　本発明は回転砥石７の位置検知手段としてサーボモータ１１の回転結果を数値化して表示するようにしたもので、図１４に操作パネルを示す。２５はタッチパネルのメイン画面、２６はボタン類で、電源スイッチ２６ａ、運転準備スイッチ２６ｂ、上昇ボタン２６ｃ、下降ボタン２６ｄ、全停止ボタン２６ｅ、非常停止ボタン２６ｆ、ブザーボタン２６ｈ、ブザー停止ボタン２６ｉである。
　なお、粉砕機１は、サーボモータ１１の設定を行うことでリング状固定砥石６と回転砥石７とのクリアランスを一定に保持して行う自動運転が可能なものである。
　粉砕機１の機体に本発明の診断装置を構成する振動センサー２７を設け、この振動センサー２７の反応をもとに回転砥石の移動を制御することとした。
　この振動センサー２７の取付けは、粉砕機１の機体枠内でもよいが、図１に示すように中央に供給ホッパー２を取り付けた上蓋５に設けるものとした。
　振動センサー２７の取付け位置として上蓋５を選択したのは、上蓋５は下方にグラインダー本体３を設けているので振動を検知し易く、かつ、邪魔にならず、取付け易いもので、本発明装置を備えていない粉砕機１に対しても後からの取付も容易であることによる。
　振動センサー２７には出力コード２８が着脱自在に接続され、ロックリング２９により固定する。
　振動センサー２７の出力は、振動を捉え数値化することによって接触状態もしくはクリアランスを適正にたもつＥＰ（イージーポイント）を設定する補助機器（パソコン）に導入し、ここでのプログラミングをもとに、サーボモータ１１の回転を制御するものである。
　図７にメイン画面２５の画面例を示す。また、図８に補助機器として振動値の設定画面を示す。この補助機器は振動センサー２７が砥石の振動を捉え数値化することによって接触状態もしくはクリアランスを適正にたもつＥＰ（イージーポイント）を設定するためのもので、電源ランプ３２ａと設置値ランプ３２ｂによる表示ランプ３２とデジタルモニター３３、モードキー３４ａ、ＵＰキー３４ｂ、ＤＯＷＮキー３４ｃ、セットキー３４ｄとを有する。
　前記補助機器は制御器としてパソコンを内蔵するものであり、振動センサー２７とセットして販売することができる。
　図２に示すように、上蓋５にネジ孔３６を穿ち、ここに振動センサー２７の下方に突出するネジ３７を螺合して振動センサー２７を立設する。
　振動センサー２７には出力コード２８がソケット機構により着脱自在に接続され、ロックリング２９により固定する。
　図４は出力コードの端部の斜視図であるが、図中３９は出力コード２８側のソケット孔、３８はキー溝、４０は振動センサー２７のキーで、このキー４０がキー溝３８に係合して位置合わせが行なわれ、ロックリング２９を回して下降させ、跨らせる。
　上蓋５には取手４１が設けられるが、この取手４１に指をかけて上蓋５を外す場合には、出力コード２８を振動センサー２７から外しておけば支障にならない。
　なお、前記振動センサー２７の取り付け位置としては、上蓋５ではなく、上蓋５以外のハウジング３５、例えば、上蓋５のフタ受けの近傍で、ハウジング３５の上床面なども選択できる。
　次に、使用法について説明する。図９は運転の模試図であるが、粉砕機１に粉砕を行う食材または材料３０を投入し、回転砥石７を回転させながら、固定砥石６側に移動させて粉砕を行う食材または材料３０に接触させる。
　この接触した地点のサーボモータ１１での砥石の位置情報および振動センサー２７の振動情報は判定される。
　接触した時点で振動センサー２７において振動の有無を感知し、接触状態の適否を判定する。この適否判定は振動センサー２７が検知する振動波形をあらかじめパソコンに記憶した適正振動波形と比較し、その異同の大きさによりリング状固定砥石６及び回転砥石７の適正なクリアランスの設定を行うものである。
　このあらかじめ記憶した適正振動波形については、運転準備として図８に示す本発明の補助機器を用いて下記の操作を行い設定する。
１．サーボモータ１１を手動で操作し、回転砥石７がほんの僅かにリング状固定砥石６に接触する（空擦りをして砥石の粉が出ない範囲で）位置を探す。
２．食材または材料３０を投入し、運転（砥石の回転）を開始する。
３．サーボモータ１１を手動で操作し、振動センサー２７の出力がデジタルモニター３３で希望の振動値になるまで回転砥石７を上昇させる。
　希望の設定値は、原料や砥石の種類、条件によって変わるので、予め手動で操作し処理された原料の細かさや温度や状態で、振動値を決めておくものである。特に、食材または材料３０の希望の粒子を得る試みを行い、最適粒子が得られる回転砥石７の位置における振動センサー２７の振動値を把握し、この数値を基に運転制御を行うものである。
　運転においては、タッチパネルのメイン画面２５にて粉砕を行う食材または材料３０に合った接触検知値を入力する。
　インバータ盤にて運転し、インバータ回転数を調節する。上昇、下降ボタンを押して初期位置付近まで昇降する。このようにして、運転時には回転砥石７を回転させながら、固定砥石側に移動させて粉砕を行う食材または材料３０に接触させ、接触した位置をゼロ点として回転砥石７と固定砥石６とのクリアランスを調整するものである。
　希望の振動値になったら、自動運転（タッチパネル）に移行する。図７にその操作パネルを示す。
　以後、希望の数値の範囲内（任意設定値）に収まるように自動で砥石が上下し運転を継続する。なお、自動運転の一例として、温度の上昇でシャフトが伸び砥石の接触が強くなると、振動値も上昇し設定範囲から外れると、回転砥石を下降させ設定値内に収まるように制御する。
　また、シャフトの熱膨張が終わり砥石の接触により砥石が摩耗していくと振動値が下がるので今度は回転砥石７を上げるような運転制御が行われる。
　自動運転を図７に示す終了する場合は自動停止（タッチパネル）を押す。
　停止したら図１の全停止ボタン２６ｅを押す。
　本発明において振動センサー２７の取り付け位置は重要であり、上蓋５を含むハウジング３５のいずれかを選択することが必要である。なお、この場合、固定砥石６に接触させることや、直接取り付けることも選択肢に含む。

Next, usage will be described. FIG. 9 is a schematic drawing of the operation, but the food or material 30 to be crushed is put into the crusher 1, and while rotating the rotary grindstone 7, it is moved to the fixed grindstone 6 side to move to the grindstone 6 to crush it. Make contact.
The position information of the grindstone at the servomotor 11 at the contact point and the vibration information of the vibration sensor 27 are determined.
At the time of contact, the presence or absence of vibration is detected by the vibration sensor 27 to determine whether the contact state is appropriate. In this suitability determination, the vibration waveform detected by the vibration sensor 27 is compared with the appropriate vibration waveform stored in the personal computer in advance, and the appropriate clearance of the ring-shaped fixed grinding stone 6 and the rotating grinding stone 7 is set by the different sizes. is there.
The pre-stored proper vibration waveform is set by performing the following operation using the auxiliary device of the present invention shown in FIG.
1. The servomotor 11 is manually operated to find the position where the rotary grindstone 7 contacts the ring-shaped fixed grindstone 6 (in the range where the powder of the grindstone does not come out by rubbing).
2. Feed the food or material 30 and start operation (rotation of the grinding wheel).
3. The servomotor 11 is manually operated to raise the rotary grindstone 7 until the output of the vibration sensor 27 becomes a desired vibration value on the digital monitor 33.
Since the desired set value changes depending on the type of raw material and the type of grinding stone and conditions, the vibration value is determined in advance according to the fineness, temperature and state of the raw material manually operated and processed. In particular, an attempt is made to obtain desired particles of the food or the material 30, the vibration value of the vibration sensor 27 at the position of the rotary grindstone 7 at which optimum particles are obtained is grasped, and operation control is performed based on this numerical value.
In operation, on the main screen 25 of the touch panel, a contact detection value matching the food or material 30 to be crushed is input.
Operate with the inverter board and adjust the inverter rotation speed. Press the UP and DOWN buttons to move up and down to near the initial position. In this way, while rotating the rotary grindstone 7 at the time of operation, it is moved to the fixed grindstone side to be in contact with the food material or material 30 to be crushed, and the contact position is a zero point, the clearance between the rotary grindstone 7 and the fixed grindstone 6 To adjust the
When desired vibration value is obtained, shift to automatic operation (touch panel). FIG. 7 shows the operation panel.
Thereafter, the grinding wheel moves up and down automatically so as to be within the desired numerical range (arbitrary set value), and the operation is continued. As an example of the automatic operation, when the shaft extends and the contact of the grinding stone becomes strong due to the rise of temperature, the vibration value also rises and falls out of the set range, the rotary grinding stone is lowered and controlled to fall within the set value.
In addition, since the vibration value is lowered as the grinding wheel wears due to the thermal expansion of the shaft ending and the grinding wheel wears due to the contact of the grinding wheel, operation control to raise the rotary grinding wheel 7 is performed this time.
When the automatic operation is ended as shown in FIG. 7, the automatic stop (touch panel) is pressed.
When stopped, all stop button 26e in FIG. 1 is pressed.
In the present invention, the mounting position of the vibration sensor 27 is important, and it is necessary to select one of the housings 35 including the upper lid 5. In this case, contacting the fixed grinding stone 6 or directly attaching is also included in the options.
In order to confirm the effect of the present invention, the mounting position of the vibration sensor 27 was changed as shown in FIG. 5 and FIG. The results are shown in Table 1 below. Here, the casing 42 constitutes the upper part of the airframe 4 and refers to the lower part of the housing 35.
