入插頭4的插座5。又，從設於插頭4的開孔將 元件（P i e ζ 〇元件）8的板狀檢測構件6插入T型/ 又，插頭4及插座5係螺合固定，另外，在螺紋 插座5及接頭部2b之間亦螺合固定。 T型管接頭2的主管部2 a係連接於未圖示的潤 配管，具有作為潤滑劑流通部的功能。另外，上 2 b係從主管部2 a的中央垂直延伸，藉由該接頭 紋接管3、插頭4及插座5，構成插入檢測構件6 件插入部1 5。又，除T型管接頭2外，也可使用 於Y型管接頭或十字管接頭的接頭，但從構成的 慮最好使用T型管接頭2。 又，螺紋接管3及插座5係以對應檢測構件6 調整檢測構件插入部1 5的長度為目的而設者，因 326\專利說明書(補件)\93-03\93100876 14 於該壓電 為：感測 給狀態監 成。在連 械的軸承 的接頭部 皂接著插 具有壓電 ;接頭2。 接管3、 滑劑供給 述接頭部 部2b、螺 的檢測構 安裝插頭 容易性考 的長度而 此並非為 1271486 必備的構成。但是，正如後續之說明 器感度’檢測構件6的長度需要有某 最好有設置。 檢測構件6的上端，係利用樹脂7 上部部分，藉此可防止潤滑劑從T型 檢測構件6的下端，係以非受限狀態 流通部的功能的主管部2 a内。據此， 於主管部2 a時，藉由潤滑劑流在檢測 位以致彎曲變形，壓電元件8因該彎 產生電壓。 如圖2之縱剖面圖所示，檢測構件 住形成為長形的角板形的壓電元件8 彎曲性的被覆材1 0被覆其全體的構； 在壓電元件8的兩面分別設有端部 極，利用焊錫等連接著用以取出由壓 壓的導線1 1。也就是說，在伴隨著潤 用於壓電元件8而產生歪曲的情況，— 壓電元件8可使用彎曲型者，亦即 變形而產生電壓者，並可為由一片的 型者，也可為由黏貼2片壓電元件而 變型壓電元件藉由力F彎曲時，一側 的元件收縮而使兩元件均產生電荷， 又，壓電元件8也可為黏貼3片以上 成者。構成壓電元件8的材料只要為 326\專利說明書(補件)\93-03\93100876 15 ，為獲得良好的感測 種程度的長度，因此 固]匕以固定插頭4的 ί接頭2洩漏。另外， 位於具有作為潤滑劑 當供給潤滑劑而流通 構件6的下端產生變 曲變形而誘發電荷， 6具有由補強板9夾 的兩面，再由具有可 卜 電極，在該端部電 電元件8所產生的電 滑劑流的彎曲應力作

到操作便利性及製造成本，最好為長形的長方體形狀。 補強板9係為使不易引起壓電元件8因彎曲應力造成破 損而設者。只要為對指定的彎曲應力，可防止壓電元件8 的破損的材料便可，若與壓電元件8絕緣的話，為鐵等的 金屬或塑膠等的高分子材料亦可。又，補強板9可設於壓 電元件8的兩面，也可設於單面。 另外，被覆材1 0係用以將壓電元件8與補強板9 一體 化而予以保護，同時，若在壓電元件8破損的情況，可防 止破損片混入潤滑劑中而產生設備異常。該被覆材1 0尤其 在由脆的陶瓷形成壓電元件8的情況相當有效。作為被覆 材1 0的材料，只要為具有可彎曲性的充分保護功能者便 可，而以樹脂材料為佳。例如，較適宜使用熱收縮性薄膜。 此等補強板9及被覆材1 0，係根據壓電元件8的材質、 使用條件等而可為多層構造。另外，並不一定要具備補強 板9及被覆材1 0，也可不使用補強板9而由被覆材1 0直 接被覆壓電元件8來形成檢測構件6，亦可將由補強板9 夾住壓電元件8者直接使用作為檢測構件6。又，若壓電 元件8具有充分的強度或韌性，也可由壓電元件8單獨構 成檢測構件6。但是，被覆材1 0最好為具有強化對壓電元 件8的防濕、電性絕緣的效用而設者。 16 326\專利說明書(補件)\93-03\93100876 1271486 圖3為顯示將上述潤滑劑之供給狀態監視感測器1組入 潤滑劑供給迴路的構成例圖。 潤滑劑之供給狀態監視感測器1，係組入以一定間隔供 給潤滑劑的自動集中潤滑裝置所構成的潤滑劑供給迴路的 一部分。具體而言，設於從分配閥1 2所分叉的潤滑劑供給 配管1 3的中間。為可監視潤滑劑被供給至潤滑部位之情 形，最好安裝於潤滑部位之軸承1 4的極近處或軸承1 4本 身。 在如上的構成的潤滑劑之供給狀態監視感測器中，在透 過潤滑劑供給配管1 3將潤滑劑供給潤滑部位時，在T型管 接頭2的主管部2a產生如圖1所示的箭頭方向的潤滑劑 流。於是5檢測構件6以藉由樹脂7所固定的部分作為支 點而向潤滑劑流的下游方向彎曲。其結果，在壓電元件8 的表背面產生各自相反的電荷而於導線1 1的兩端產生電 壓。因此，藉由檢測該電壓，可把握潤滑劑之供給狀態。 圖4顯示此時的輸出波形。圖4之縱軸表示產生於導線 1 1的電壓，橫軸表示經過時間。如圖4所示，當間歇的潤 滑劑壓送流作用於檢測構件6而產生彎曲時，產生脈衝狀 的電壓1 7。然後，當潤滑劑流停止時，檢測構件6藉由壓 電元件8與補強板9的彈性力而恢復為原來的狀態。此時， 被加上的歪曲減少，結果產生具有相反的極性的脈衝狀的 電壓1 8。 如此，藉由間歇的潤滑劑流產生形成正負之對的電壓脈 衝，如圖4所示，可獲得雜訊少的波形。據此，檢測構件 17 326\專利說明書(補件)\93-03\93100876 1271486 6的長度越長歪曲變得越大，因此可獲得更大的產生電壓。 在本實施形態之潤滑劑之供給狀態監視感測器中，係為 基於使用壓電元件8的如上原理而設計，因此即使在進行 產生的電壓也大的訊號處理時，也為不需要特別的放大處 理、雜訊除去處理的位準。另外，因為使用壓電元件8， 可把握不使用電源的潤滑劑的供給狀態。據此，可將潤滑 劑之供給狀態監視感測器設為小型且廉價者。 另外，根據該原理，流動的潤滑劑量越多，檢測構件6 的歪曲越大，因此可知所產生的電壓17的峰值也變大。據 此，若電壓1 7為一定以上的大小便可供給充分量的潤滑 劑，相反地，若電壓1 7為一定以下的大小，便可判定所供 給的潤滑劑量不充分。 又，如此般，以將具有壓電元件8的檢測構件6的上端 固定，使下端位於供給潤滑劑時所形成的潤滑劑流中的位 置的方式予以配置，以藉由潤滑劑流而於下端產生變位而 彎曲變形的方式，藉由彎曲變形而於壓電元件8產生電 Λ 壓，因此，較檢測如上述專利文獻2的潤滑劑的脈動壓力 的情況，可獲得本質上的大輸出，在各潤滑部位附近可確 實監視潤滑劑之供給狀態。 以下，說明確認如此的效果的實驗。 準備如圖5Α所示的作為潤滑劑的潤滑脂供給裝置，如 圖示般安裝上述圖1所示的構造的實施例的潤滑劑的供給 狀態監視感測器，及圖5Β所示的構造的比較例的潤滑劑的 供給狀態監視感測器。也就是說，實施例的供給狀態監視 18 326\專利說明書(補件)\93-03\93100876 1271486 感測器係為在單手握持檢測構件的狀態垂直安裝於τ型管 接頭（1 / 4Β )内者，比較例的供給狀態監視感測器，係為模 擬上述專利文獻2 (日本專利特開平1 - 1 9 7 6 2 3號公報）的感 測器，在兩面握持檢測構件的狀態水平安裝於Τ型管接頭 (1 / 4 Β )内者。作為構成檢測構件的壓電元件，係使用 5 m m X 6 0 m m X 0 · 5 m m的I太酸錯S吏船系陶瓷，在其上面被覆熱收 縮性薄膜（商品名SUM I TUBE)而作為檢測構件。 屬潤滑劑之潤滑脂的供給，係使用法伐爾泵（i a r v a 1 p u m p )而間歇性地進行。圖6顯示此時的電壓檢測狀態。如 該圖所示，相對.於比較例的情況中藉由潤滑脂的供給可獲 得至多為數mV的脈衝，在本實施例的情況可獲得超過2 0 mV 的脈衝。由此可以確認，根據本發明的構成可更為確實地 監視潤滑劑的供給狀態。 其次，說明使用以上說明的潤滑劑的供給狀態監視感測 器1以監視潤滑劑的供給狀態用的監視裝置的構成。 圖7為顯示第1實施形態之潤滑劑之供給狀態監視裝置 的構成圖。 第1實施形態之潤滑劑之供給狀態監視裝置，係為於潤 滑劑的供給狀態監視感測器1設置計數裝置2 5者，為連接 潤滑劑的供給狀態監視感測器1的導線1 1與計數裝置2 5 的輸入端子而構成者。 在產生潤滑劑流的過程中，由檢測構件6檢測該潤滑劑 流，藉由計數裝置2 5計數供給潤滑劑的次數並予以顯示。 在此，預先記錄下計數裝置2 5的初期計數，在經過一定時 19 326\專利說明書(補件)\93-03\93100876 1271486 間後，確認該計數裝置2 5所顯示的計數，藉由減法演 可算出在該一定時間内所供給的潤滑劑的供給次數。 此，在未計數的情況，即為未供給潤滑劑或供給量少 況。據此，藉由比較該算出的次數及一定時間内所應 的潤滑劑的供給次數，便可判定是否正常供給潤滑劑 該情況，因為使用壓電元件8作為檢測構件6，因 需要如上述的用以供電給檢測構件6的電源，而僅對 數裝置2 5供給電源即可，因此藉由在計數裝置2 5使 型電池等，即可使裝置全體小型化且更為廉價。 圖8為顯示濶滑劑之供給狀態監視裝置的另一實施 的構成圖。本實施形態之裝置係在潤滑劑的供給狀態 感測器1設置計數裝置2 5、定時裝置2 6及警報裝置 利用由計數裝置2 5所計數的潤滑劑的供給次數及： 裝置2 6的時間資訊，由未圖示的演算裝置，判斷是否 定時間内供給潤滑劑，若為在指定時間内未供給潤滑 情況或供給量少的情況，由警報裝置2 7發出警報。 在本實施形態中，可以較小的裝置監視潤滑劑的供 良並發出警報。因此可將計數裝置2 5、定時裝置2 6 報裝置2 7構成為一體，也可為將此等分離而由訊號線 的構成。 另外，警報裝置27可藉由光、聲音等而發出警報： 也可為不只由電子顯示器顯示而由機械切換來表示警 者。 圖9為顯示潤滑劑之供給狀態監視裝置的又一實施 326\專利說明書(補件)\93-03\93100876 20 算便 在 的情 供給 〇

增加的情況，判定為潤滑劑的供給不良，並由警報裝置2 7 發出警報。 本實施形態之裝置，係為設置分配閥變位感測器2 8以 取代另一實施形態之裝置的定時裝置2 6，並檢測分配閥的 變位，於分配閥1 2的作動時監視潤滑劑的供給狀態。因 此，相較於使用定時裝置2 6之情況，可快速檢測出異常。 圖1 0為顯示潤滑劑之供給狀態監視裝置的再一實施形 態的構成圖。本實施形態之裝置係由潤滑劑的供給狀態監 視感測器1、計數裝置2 5、警報裝置2 7及潤滑劑供給泵起 動訊號2 9所構成者。 潤滑劑供給泵起動訊號2 9從導通（ON )開始，在指定時 間内計數裝置2 5的計數未增加的情況，判定為潤滑劑的供 給不良，並由警報裝置27發出警報。 本實施形態之裝置，係為設置潤滑劑供給泵起動訊號2 9 以取代另一實施形態之裝置的定時裝置2 6，檢測潤滑劑供 給泵起動訊號2 9的導通，以監視潤滑劑的供給狀態。因 此，相較於使用定時裝置2 6之情況，可快速檢測出異常。 圖1 1為顯示潤滑劑之供給狀態監視裝置的再一實施形 21 3%\專利說明書(補件)\93-03\93100876 1271486 態的構成圖。本實施形態之裝置係於第1或另一實施形態 之裝置設置無線裝置3 0及資料收集裝置3 1者。 本實施形態之裝置中，即使是對於因安全上的問題等而 在設備的工作狀態中無法容易接近的設備，仍可收集有關 潤滑劑的供給狀態的資料而予以監視。該情況收集的資料 可為計數值，也可為潤滑劑的供給狀態的判定結果。 圖1 2為顯示潤滑劑之供給狀態監視裝置的再一實施形 態的構成圖。本實施形態之裝置係作為生產線監視系統 (Ο η _ 1 i n e m ο n i t 〇 r i n g s y s t e m )的構成。潤滑劑的供給狀態 監視感測器1係透過導線1 1而連接於計數裝置2 5及資料 收集監視裝置3 5，並進一步利用未圖示的有線、無線、電 話線路、L A N等將有關潤滑劑的供給狀態的資料傳送給個 人電腦36 。 藉由該構成，尤其關於重要的設備，可遠距離地經常集 中監視潤滑劑的供給狀態。又，生產線監視系統並不限定 於圖1 2所示的形態，也可為與上述的實施形態組合，具備 資料收集監視裝置3 5及個人電腦3 6的構成，也可使用資 料收集監視裝置3 5來監視由各個實施形態所產生的資 料。又，可直接將潤滑劑的供給狀態監視感測器1的輸出 訊號直接連接於資料收集監視裝置3 5。 如上述的各實施形態的潤滑劑之供給狀態監視裝置，係 為使用設於潤滑部位或潤滑劑供給配管的潤滑劑的供給狀 態監視感測器1，來監視所供給的潤滑劑的狀態是否供給 一定以上的·潤滑劑。藉由在如此的潤滑劑的供給狀態監視 22 326\專利說明書(補件)\93-03\93100876 1271486 感測器1中，如上述各實施形態，組合根據需要的各零件、 裝置來構成監視裝置，在附加種種的功能、種種的應用中， 可形成監視潤滑劑的供給狀態所必要的充分的裝置構成。 因此，可監視於潤滑部位或潤滑部位附近的潤滑劑供給狀 態，並可將潤滑劑的供給不良引起的初期異常防範於未然。 又，本發明並不僅限於上述實施形態，其可作種種的變 4匕。例如，在上述實施形態中，雖例示有潤滑脂來作為潤 滑劑，但也可使用潤滑油等的油狀及脂狀的種種的潤滑 劑。另外，在上述實施形態中，雖顯示將本發明之裝置應 用於自動集中潤滑裝置的例子，但也可應用於手動的潤滑 裝置。 如圖1 3所示，也可為直接將插頭4插入T型管接頭2 上部，再從設於該插頭4的開口將檢測構件6插入T型管 接頭2内部，由樹脂7將插頭4的上部部分固化，以固定 檢測構件6的單側端，同時防止潤滑劑從T型管接頭2的 洩漏的構成。 另外，如圖1 4所示，也可為將插入有插頭4的螺紋接 管3連接於T型管接頭2的接頭，再從設於該插頭4的開 口將檢測構件6插入T型管接頭2内部，由樹脂7將插頭 4的上部部分固化，以固定檢測構件6的單側端，同時防 止潤滑劑從T型管接頭2的洩漏的構成。 圖1 5為顯示將潤滑劑之供給狀態監視感測器組入潤滑 劑供給迴路的構成例圖。 潤滑劑之供給狀態監視感測器1，係組入以一定的時間 23 326\專利說明書(補件)\93-03\93100876 1271486 間隔供給潤滑劑的自動集中潤滑裝置所構成的潤滑劑供給 迴路的一部分。具體而言，設於從分配閥1 2所分叉的潤滑 劑供給配管1 3的中間，但為了可監視潤滑劑被供給潤滑部 位的情形，最好可安裝於潤滑部位之軸承1 4的極近處或軸 承1 4本身。 但是，在該設備的設置場所的環境中，也有難以設於轴 承1 4的附近情況。此時，如圖1 6所示，最好選定潤滑劑 之供給狀態監視感測器1的破損少的場所進行設置。 圖1 7為簡要顯示本發明之另一實施形態之潤滑劑之供 給狀態監視感測器的構成的剖面圖。 另一實施形態之潤滑劑之供給狀態監視感測器，係為於 第1實施形態之潤滑劑之供給狀態·監視感測器中，使用Y 型管接頭2 1以替代T型管接頭2的構成。 在本實施形態中，因為可將潤滑劑之供給狀態監視感測 器的高度抑制為較低，因此有可應用於與其他的裝置、機 器等干涉的狹窄的場所的優點。 圖1 8為簡要顯示本發明之又一實施形態之潤滑劑之供 給狀態監視感測器的構成的剖面圖。 又一實施形態之潤滑劑之供給狀態監視感測器，係為於 第1實施形態之潤滑劑之供給狀態監視感測器中，使用十 字型管接頭2 2以替代T型管接頭2的構成。然後，將插頭 4分別插入十字型管接頭2 2的與流動方向垂直的2個部位 的端部，再從設於一個插頭4的開口將具有感測元件的板 狀檢測構件6插入十字型管接頭2 2，由兩端的插頭4承接 326\專利說明書(補件)\93-03\93100876 24 1271486 並支持。 在本實施形態中，係為貫穿潤滑劑供給配管1 3而設置 檢測構件6，從兩側保持檢測構件6的構造，因此可將單 側的高度設為較低。 圖1 9為簡要顯示本發明之再一實施形態之潤滑劑之供 給狀態監視感測器的構成的剖面圖。 再一實施形態之潤滑劑之供給狀態監視感測器，係為於 第1實施形態之潤滑劑之供給狀態監視感測器中，使用肘 型彎管接頭2 3以替代T型管接頭2的構成。 在本實施形態中，可將潤滑劑之供給狀態監視感測器應 用於轉換潤滑劑供給配管1 3的潤滑劑流方向的部位。又， 在本實施形態中，為感度良好地檢測潤滑劑流，最好將檢 測構件6配設於上游側的潤滑劑供給配管1 3的出口附近的 位置。 又，管接頭除肘型彎管接頭2 3外還可使用彎管接頭。 在此，肘型彎管接頭2 3、彎管接頭的角度不限於9 0度， 而可由任意的角度所構成。 圖2 0為顯示本發明之再一實施形態之潤滑劑之供給狀 態監視感測器的構成的剖面圖。 再一實施形態之潤滑劑之供給狀態監視感測器，係為與 第1實施形態相同之構成，但在檢測構件6使用歪曲檢測 元件以取代壓電元件8的方面不同。 圖2 1為從顯示檢測構件6的構成的側面所見的剖面圖。 檢測構件6係使用歪曲測量儀1 6作為歪曲檢測元件， 25 326\專利說明書(補件)\93-03\93100876 1271486 將該歪曲測量儀黏貼於補強板9上，再由具彈性力的被覆 材1 0被覆全體的構成。然後，在設於歪曲測量儀1 6的端 部的電極，利用焊錫等連接導線1 1。 在此，補強板9只要為對指定的彎曲應力可產生歪曲的 材料即可，也可為鐵等的金屬或塑膠等的高分子材料。 另外，歪曲測量儀1 6的安裝，不僅黏貼在補強板9的 單側，亦可黏貼於兩側。又，也可為使用虛設測量儀（d u m m y g a u g e )以補償溫度變化的方式的構成，亦可為使用公知的 各種手法作為通常測定方法的構成。 如此般，在將潤滑劑供給連接於潤滑劑供給配管1 3的 潤滑劑之供給狀態監視感測器時，產生如圖2 0所示箭頭方 向的潤滑劑流。於是，檢測構件6係將由樹脂7所固定的 部分作為支點而向潤滑劑流的下游方向彎曲。其結果，歪 曲測量儀1 6的基準線變形而使其電阻值發生變化。利用由 未圖示之惠斯登電橋檢測該電阻值的變化而作為電壓變化 以測定歪曲量。 圖2 2為顯示使用歪曲檢測元件之潤滑劑之供給狀態監 視感測器的輸出波形圖。 縱軸表示歪曲量，橫軸表示從左至右所經過的時間。藉 由分3次間歇性的潤滑劑壓送流作用於檢測構件6而產生 的歪曲，可獲得3個山形的歪曲量波形1 9 a、1 9 b、1 9 c。 然後，若潤滑劑流停止時，檢測構件6係由補強板9的彈 性力恢復為原來的狀態。其結果，歪曲量朝向原來的狀態 而開始復元。如此，藉由間歇性的潤滑劑流可獲得山形的 26 326\專利說明書(補件)\93-03\93100876 1271486 歪曲量波形，該波形成為雜訊少的波形。 在此，在圖2 2之波形，連續山形的歪曲量波形藉由補 強板9的彈性力直到恢復為原來的狀態為止需要時間，因 此，只要選定彈性力較高的材料為補強板9，便不可產生 該現象。不過在應用每數小時供給潤滑劑的自動集中潤滑 裝置的情況，該現象並不是問題。 另外，作為歪曲測量儀1 6所具的缺點，可舉出如潤滑 劑在溫度變化的情況的零點的偏移，但藉由上述溫度補償 的應用或使用高通濾波器的訊號處理，可獲得解決。 又，潤滑劑之供給狀態監視感測器，係為在檢測構件6 僅使用歪曲測量儀1 6的簡單構造。因此，若與應用壓力感 測器的情況比較，可獲得小型、廉價的潤滑劑之供給狀態 監視感測器。 接著，說明除上述說明的功能之外，還具備計數潤滑劑 的供給次數，並判定潤滑劑的供給狀態用的功能的潤滑劑 之供給狀態監視裝置的構成。 圖7為顯示第1實施形態之潤滑劑之供給狀態監視裝置 的構成圖。作為本實施形態的變化例，在使用圖1 3所示之 供給狀態監視感測器的情況，可將計數裝置2 5與T型管接 頭2直接接合。 圖23A、圖23B及圖23C為簡要顯示本發明之另一實施 形態之潤滑劑之供給狀態監視裝置的構成的剖面圖。 圖2 3 A、圖2 3 B及圖2 3 C之潤滑劑之供給狀態監視裝置， 係為於圖7之潤滑劑之供給狀態監視裝置中，將計數裝置 27 326\專利說明書(補件)\93-03\93100876 1271486 2 5設置為可旋轉自如的構成。 也就是說，圖2 3 A係以檢測構件6的長方向作為中心 軸，將計數裝置2 5構成為可繞該中心軸旋轉自如。另外， 圖2 3 B係以檢測構件6垂直於承受潤滑劑的動壓的面的方 向作為中心軸，將計數裝置2 5構成為可繞該中心軸旋轉自 如。又，圖2 3 C係構成為可繞圖2 3 A及圖2 3 B的兩中心軸 旋轉自如。 根據該實施形態，與設置潤滑劑之供給狀態監視裝置的 狀態無關，可以適宜的角度使計數裝置25旋轉，因此無須 變化讀取者的姿勢而可容易地讀取計數值。 圖2 4為簡要顯示本發明之潤滑劑之供給狀態監視裝置 的再一實施形態的剖面圖。 圖2 4之潤滑劑之供給狀態監視裝置，係於圖7之潤滑 劑之供給狀態監視裝置中，將計數裝置25可裝卸自如地構 成於T型管接頭2或螺紋接管3，藉由導線1 1連接於檢測 構件6及計數裝置2 5。由於可裝卸自如地構成計數裝置 2 5，故於計數裝置2 5設置夾緊機構或吸著機構。 圖2 5 A及圖2 5 B為顯示將計數裝置2 5安裝於潤滑劑供 給配管1 3的狀態的圖。圖2 5 A顯示安裝狀態的前視圖，圖 2 5 B顯示安裝狀態的剖面圖。計數裝置2 5可藉由夾緊機構 3 4安裝於潤滑劑供給配管1 3。在此，例如，可使用夾子等 的廉價物品作為夾緊機構3 4。 圖26A、圖26B及圖26C為顯示將計數裝置25安裝於T 型管接頭2上的狀態的圖。圖2 6 A顯示安裝狀態的仰視圖， 28 326\專利說明書(補件)\93-03\93100876 1271486 圖2 6 B顯示安裝狀態的前視圖，圖2 6 C顯示安裝 視圖。計數裝置2 5可藉由夾緊機構3 4安裝於T 2或螺紋接管3。 根據圖2 4的實施形態，即使在作業中因安全_ 而無法接近的場所安裝檢測構件6等的情況，仍 的場所安全地讀取計數值。另外，利用將計數裝】 為裝卸自如，可將潤滑劑之供給狀態監視裝置的 的構造簡要化，可使裝置廉價。又，在本實施形 明了使用夾緊機構3 4的構成，但並不限於此例， 計數裝置2 5上設置使用磁鐵等的吸著機構而構/ 卸自如。 圖2 7為簡要顯示本發明之再一實施形態之潤i 給狀態監視裝置的構成的剖面圖。 圖2 7之潤滑劑之供給狀態監視裝置，係為於f 滑劑之供給狀態監視裝置中，由可撓性管2 0連接 6及計數裝置2 5間的構成。該可撓性管2 0係為 力於計數裝置2 5而可自由伸縮變形，另外，將施 後仍可保持形狀的素材或構造所構成。 根據本實施形態，可容易地將計數裝置2 5移i 的位置，因此可容易進行計數值的讀取，可將有 監視的作業效率化。又，在本實施形態中，可為 置2 5具備上述的夾緊機構或吸著機構的構成。 圖2 8為簡要顯示本發明之再一實施形態之潤 給狀態監視裝置的構成的剖面圖。 326\專利說明書(補件)\93-03\93100876 29 狀態的側 型管接頭 -的理由 可在較遠 ί 2 5構成 結合部分 態中，說 也可為在 〔為可裝 卜劑之供 ]7之潤 檢測構件 用施加 加力撤去 !;於合適 關點檢、 於計數裝 ^劑之供 1271486 圖2 8之潤滑劑之供給狀態監視裝置，係於圖7之潤滑 劑之供給狀態監視裝置中，具備可設定並顯示日期的曰期 設定機構。 為判定是否正常供給有潤滑劑，有調查指定期間内的計 數數值的必要。在此，利用在潤滑劑之供給狀態監視裝置 預先設定·顯示該重設計數器後的月日（亦即起算日），便 可在現場立即判斷是否正常供給有潤滑劑。 本實施形態中，作為日期設定機構，係使用旋轉顯示數 字的旋轉輪以設定日期的旋轉式日期設定器2 4的構成，例 如也可使用如圖2 9所示的旋轉記載有數字的圓板而設定 日期的旋轉式日期設定器3 3的構成。若於計數裝置2 5的 背面設置該旋轉式日期設定器3 3，而成為點檢者藉由+驅 動器來設定日期的構成的話，便可將潤滑劑之供給狀態監 視裝置構成為小型化。 圖3 0為簡要顯示本發明之再一實施形態之潤滑劑之供 給狀態監視裝置的構成的剖面圖。 .圖3 0之潤滑劑之供給狀態監視裝置，係於圖7之潤滑 劑之供給狀態監視裝置中，計數裝置2 5具備重設計數值的 重設開關32。 為判定是否正常供給有潤滑劑，有調查指定期間内的計 數數值的必要。在此，利用在潤滑劑之供給狀態監視裝置 設置計數器的重設開關3 2，只要在點檢時重設計數器，便 可把握下一次點檢時的正常時的計數值，可在現場立即判 斷是否正常供給有潤滑劑。 30 326\專利說明書(補件)\93-03\93100876 1271486 圖3 1為顯示本發明之另一實施形態之潤滑劑之供給狀 態監視裝置的計數裝置2 5的構成的方塊圖。 來自檢測構件6的訊號係透過導線1 1被輸入計數裝置 2 5。本實施形態中，計數裝置2 5具備計數器部4 0，並具 有計數潤滑劑的供給次數並顯示該值的功能。又，,3 1 未圖示有關計數器的重設功能。 本實施形態之潤滑劑之供給狀態監視裝置，係為依最小 限的構成的檢測裝置，因此可作成小型且廉價的裝置。 圖3 2為顯示本發明之又一實施形態之潤滑劑之供給狀 態監視裝置的計數裝置2 5的構成的方塊圖。 圖3 2之計數裝置2 5，係由計數器部4 0、定時器部41、 演算部4 2、警報部4 3及警報設定部4 4所構成。 本實施形態中，根據由計數器部4 0所計數的潤滑劑的 供給次數及定時器部4 1的時間資訊，在演算部4 2判斷是 否在指定時間内供給指定量以上的潤滑劑。在定時器的指 定時間内的供給次數為指定值以下的情況、亦即在指定時 間内未供給潤滑劑或供給量少的情況，便由警報部4 3發出 警報。在此，發出警報用的臨限值、亦即供給次數的設定 值係由警報設定部4 4所設定。 圖3 2之潤滑劑之供給狀態監視裝置，係可以較小型的 裝置來監視潤滑劑的供給不良而發出警報。又，構成計數 裝置25的各部（40〜44)可一體構成，也可適當分離而由訊 號線予以連接。 圖3 3為顯示本發明之再一實施形態之潤滑劑之供給狀 31 326\專利說明書(補件)\93-03\93100876 1271486 態監視裝置的計數裝置2 5的構成的方塊圖。其中對有關具 備圖3 2之功能的部分賦予相同的元件符號，並省略詳細說 明。 圖3 3之計數裝置2 5，在取代另一實施形態之定時器部 4 1而改採分配閥變位感測器訊號部4 5方面與前一實施形 態不同。未圖示的分配閥變位感測器係檢測分配閥1 2的作 動，分配閥變位感測器訊號部4 5將該作動時序作為潤滑劑 的供給時序而取入。然後，從分配閥1 2作動開始在指定期 間内計數器部4 0的計數未增加的情況，演算部4 2判定其 為潤滑劑的供給不良，而由警報部4 3發出警報。警報設定 部44係設定用於演算部42的判定的指定時間。 圖3 3之潤滑劑之供給狀態監視裝置，係取代圖3 2之定 時器部4 1而改設置分配閥變位感測器訊號部4 5，利用檢 測分配閥的變位，把握分配閥1 2的作動時序，以監視潤滑 劑之供給狀態。因此，相較於使用定時器部4 1之情況，可 更快速檢測出異常。 圖3 4為顯示本發明之再一實施形態之潤滑劑之供給狀 態監視裝置的計數裝置2 5的構成的方塊圖。其中，對具備 與圖3 2相同功能的部分賦予相同的元件符號，並省略詳細 說明。 圖3 4之計數裝置2 5，在取代圖3 2之定時器部41而改 採潤滑劑供給泵起動訊號部4 6方面與前一實施形態不同。 未圖示的自動集中潤滑控制裝置輸出潤滑劑供給泵起 動訊號，潤滑劑供給泵起動訊號部4 6將潤滑劑供給泵起動 32 326\專利說明書(補件)\93-03\93100876 1271486 訊號成為導通（Ο N)的時序作為潤滑劑的供給時序而取入。 然後，從潤滑劑供給泵起動訊號成為導通（ON)開始，在指 定期間内計數器部4 0的計數未增加的情況，演算部4 2判 定其為潤滑劑的供給不良，而由警報部4 3發出警報。警報 設定部44係設定演算部42的判定用的指定時間。 圖3 4之潤滑劑之供給狀態監視裝置，係取代圖3 2之定 時器部4 1而改設置潤滑劑供給泵起動訊號部4 6，利用檢 測潤滑劑供給泵起動訊號的導通（0 N )，以監視潤滑劑之供 給狀態。因此，相較於使用定時器部41之情況，可更快速 檢測出異常。 圖3 5為顯示本發明之再一實施形態之潤滑劑之供給狀 態監視裝置的計數裝置2 5的構成的方塊圖。其中對具備與 圖3 2相同功能的部分賦予相同的元件符號，並省略詳細說 明。 圖35之計數裝置25，在除了圖32之計數裝置25的構 成之外另外設置資料無線送信部4 7方面與前一實施形態 不同。 資料無線送信部4 7係將計數值、潤滑劑之供給狀態的 判定結果、警報輸出中的至少一個訊號發送給資料無線接 收裝置4 8。該送信時序可為指定週期，也可在從外部受取 資料送信要求時進行送信。 根據圖3 5之潤滑劑之供給狀態監視裝置，對因安全上 的問題等而在設備的工作狀態中無法容易接近的設備，仍 可收集有關潤滑劑的供給狀態的資料而予以監視。 33 326\專利說明書(補件)\93-03\93100876 1271486 圖3 6為顯示本發明之再一實施形態之潤滑劑之供給狀 態監視裝置的計數裝置2 5的構成的方塊圖。其中對具備與 圖3 2相同功能的部分賦予相同的元件符號，並省略詳細說 明。 圖3 6之計數裝置2 5，在除了圖3 2之計數裝置2 5的構 成之外另外設置資料收集部5 0方面與前一實施形態不同。 圖3 6之潤滑劑之供給狀態監視裝置，係用作為生產線 監視系統而構成者。也就是說，資料收集部5 0係利用有 線、無線、電話線路、L A N等的通信線路，將有關潤滑劑 之供給狀態的資料傳送給資料管理系統5 1。 根據該構成，尤其是有關重要的設備，可以遠距離經常 集中監視潤滑劑之供給狀態。又，生產線監視並不限於圖 3 6所示的形態，也可組合目前為止說明的實施形態，透過 資料收集部5 0，將在各個實施形態所產生的資料傳送給資 料管理系統5 1，以便進行監視。 又，警報部4 3可使用各種方式的構成。例如，在利用 光發出警報的情況，也可在潤滑劑之供給狀態監視裝置設 置發光二極體，形成在遠距離的場所使室内訊號燈閃爍的 構成。 另外，在利用聲音發出警報的情況，也可在潤滑劑之供 給狀態監視裝置設置揚聲器，形成在駕駛室或保全部署的 遠距離的場所透過另設的警報裝置輸出警報音、聲音的構 成。 又，在顯示警報的情況，可不只是利用電子顯示器的顯 34 326\專利說明書(補件)\93-03\93100876 1271486 示，也可改為以機械式顯示警報者。例如，如圖3 7所示，可 在計數裝置2 5上設置施行分為正常·異常顏色等分色加工 的旋轉圓板5 5，從警報顯示窗5 6顯示潤滑劑的供給狀態。 另外，如圖3 8 A所示，可在計數裝置2 5上設置利用分 色等分為正常·異常顏色的平板5 7，透過彈簧5 8抵接於 銷5 9，當產生異常時，如圖3 8 B所示，利用解除銷5 9使 平板5 7移動，而從警報顯示窗5 6顯示潤滑劑的供給狀態。 另外，警報顯示後，利用壓入桿6 0而使顯示狀態還原。 若使用以上說明的各個實施形態之潤滑劑之供給狀態 監視裝置的話，便可監視是否有必要量的潤滑劑被供給至 種種狀態之旋轉機械等的設備。更且，藉由根據需要組合 上述實施形態的各零件、裝置以構成該潤滑劑之供給狀態 監視裝置，便可建構具有新功能的潤滑劑之供給狀態監視 裝置。因此，可以必要且充分的功能來構成潤滑劑之供給 狀態監視裝置，其可將多種多樣的設備的潤滑劑的供給不 良引起的初期異常防範於未然。 又，本發明之潤滑劑之供給狀態監視裝置，不僅可適用 於潤滑脂，還可應用於油類等的潤滑劑。 又，因為上述實施形態中含有種種階段的發明，因此藉 由所揭示的複數構成要件的適宜組合，可抽出種種的發 明。例如，即使從實施形態所揭示的全構成要件去除多個 構成要件，在可解決發明所欲解決之課題部分中所陳述的 課題，及可獲得發明效果部分中所陳述的效果的情況，仍 可將去除該構成要件的構成作為發明抽出。 35 326\專利說明書(補件)\93-03\93100876 1271486 圖3 9為顯示本發明之潤滑劑之供給狀態監視方法的一 實施形態的曲線圖。本實施形態中，在該所計數的潤滑劑 的供給次數低於預先設定的指定時間内的潤滑劑的供給次 數時，判定潤滑劑之供給狀態為異常。 圖3 9之例子中，預先設定的指定時間内的潤滑劑的供 給次數為1次/ 2小時（5次/ 1 0小時），潤滑劑之供給狀態 在4 0小時内為1次/ 2小時（5次/ 1 0小時）的正常潤滑劑的 供給次數，但在4 0〜5 0小時，潤滑劑的供給次數減少為〇 次/小時，在5 0〜6 0小時再度增加為1次/ 2小時的正常潤 滑劑的供給次數。雖然在4 0〜6 0小時，潤滑劑的供給次數 低於預先設定的指定時間内的潤滑劑的供給次數，但這是 因為必須有潤滑之供給的本機器因生產線停止而被停止的 緣故。 又，在6 0〜7 0小時再度繼續為1次/ 2小時的正常潤滑劑 的供給次數，但在8 0小時低於預先設定的指定時間内的潤 滑劑的供給次數，因此判定潤滑劑之供給狀態為異常。圖 4 0為顯示將圖3 9所示之每一指定時間的潤滑劑的供給次 數對時間的變化，改為潤滑劑的供給次數的累積次數而重 新製成的曲線圖。圖4 0中也與圖3 9相同可監視潤滑劑之 供給狀態。 人· 也就是說，圖4 0中，曲線在0〜4 0小時内成為具有一定 斜率（潤滑劑的供給次數/指定時間）的直線，在4 0〜5 0小時 的需要有潤滑劑供給的本機器因生產線停止而被停止時’ 曲線暫時成為水平。其後，在5 0〜7 0小時内，再度成為具 36 326\專利說明書(補件)\93-03\93100876 1271486 有與在0〜4 0小時相同斜率的直線，但是從8 0小時開始， 斜率下降，於是判定潤滑劑之供給狀態為異常。 圖4 1係作為本發明之潤滑劑之供給狀態監視方法的另 一實施形態，顯示使用可進行峰值同步處理的裝置所測定 的感測器輸出的峰值電壓對時間的變化的一例。只要將感 測器輸出波形輸入附有峰值同步處理功能的示波器或其他 的解析裝置，便可容易獲得感測器輸出的峰值電壓。本實 施形態中，從感測器輸出波形，藉由峰值同步處理測定感 測器輸出的峰值電壓，在該峰值電壓處於預先設定的範圍 外時，判定潤滑劑之供給狀態為異常。具體而言，也可預 先於峰值電壓設定下限臨限值及上限臨限值，在峰值電壓 未滿下限臨限值時，判斷為潤滑劑的供給量減少或停止， 而在峰值電壓超過上限臨限值時，則判斷為較感測器下游 側發生堵塞。圖4 1之例子中，以預先測定的初期電壓為基 準而設定的峰值電壓的下限臨限值為0 . 1 5 V，上限臨限值 為 0. 4V 。 峰值電壓的下限臨限值及上限臨限值的設定方法，在將 資料的抽樣週期抑制在較低值的情況，最好考慮在峰值同 步處理時有或多或少會產生誤差的可能性來進行設定。 在此，圖41中，潤滑劑之供給狀態在3 0小時内，係其 峰值電壓為0 . 2 V的正常的潤滑劑的供給狀態，但在4 0小 時之時間，峰值電壓低於下限臨限值0. 1 5 V而成為0. 1 V， 因此判定潤滑劑之供給狀態為供給不足。然後，在4 0〜6 0 小時，繼續峰值電壓為0 . 1 V的狀態。在7 0小時之時間， 37 3%\專利說明書(補件)\93-03\93100876 1271486 因為峰值電壓進一步下降，峰值電壓成為零，在此，判定 潤滑劑之供給狀態為無供給。但是，在9 0小時之時間，峰 值電壓急遽上升，超過上限臨限值0. 4 V而成為0. 5 V，因 此判定其為較感測器下游側發生堵塞。這是因為若發生較 感測器下游側的堵塞，感測器部分的壓力上升，為了施加 大的力於壓電元件或歪曲測量儀，使得峰值電壓也變高。 又，不進行峰值同步處理，也有含有略微的誤差的情 況，藉由在示波器的晝面上以目視測定峰值間電壓求得 值電壓，也可容易判定潤滑劑之供給狀態。 例如，圖4 2為顯示直接使用示波器試驗性觀察感測器 輸出波形的晝面輸出的說明圖，從圖4 2之左向右，可判定 正常的潤滑劑供給狀態及潤滑劑之供給不足、無供給、發 生較感測器下游側的堵塞。又，圖4 2為將各狀態以每5 秒間隔1秒進行潤滑劑的供給的試驗結果。 圖43B如圖1、圖13及圖14所示般，為僅取出將壓電 元件用於感測器之潤滑劑之供給狀態監視裝置的感測器部 6，從前端的A部將圖4 3 A所示壓電元件切斷為各1 0 Hi m， 使用靜電容量測定器實驗性測定感測器切斷長度從 Omm(未切斷）至50mm為止的靜電容量者。 根據圖4 3 B可和，相對於完全未切斷感測器時（初期值） 的靜電容量為1 5 3 0 0 p F，而當從其前端將感測器切斷1 0 mm 時，靜電容量成為1 3 2 0 0 p F，最終，當從前端切斷5 0 m in時， 大大減少成為2 9 0 0 p F。亦即，可知壓電元件的長度與靜電 容量的大小大致成比例。 38 326\專利說明書(補件)\93-03\93100876 1271486 一般而言，使用壓電元件的感測器的異常，幾乎均為因 潤滑劑的彎曲應力造成起因於感測器固定部附近的破損的 情況，此時，若測定感測器的靜電容量的話便大大減少， 因此感測器固定部的破損的判定變得容易。 藉此，本發明中在開始潤滑劑之供給狀態的監視後，若 藉由上述圖3 9〜圖4 2所示例發現有異常，便測定感測器的 靜電容量，其較預先設定的臨限值減少時，判定感測器為 異常，可從基於潤滑劑的供給次數的計數的異常判定或基 於峰值電壓的異常判定中去除基於感測器異常者。在圖 4 3 B之例子中，考慮感測器從其前端有1 0 m m破損的情況， 預先將臨限值設定為1 2 0 0 0 p F。 亦即，藉由上述圖3 9〜圖4 2所示的本發明之潤滑劑之供 給狀態監視方法的實施形態，可判定潤滑劑之供給狀態為 異常，但是，藉由圖43A所示實驗結果，在將壓電元件用 作為感測器的情況，藉由測定感測器的靜電容量，即使簡 單地在外觀上潤滑劑之供給狀態為異常，仍可修正基於潤 滑劑之供給次數的計數的異常判定或基於峰值電壓的異常 判定，亦即，仍可從此等的異常判定中去除基於感測器異 常的異常，故較為理想。 另一方面，在如圖2 0所示的感測器中使用歪曲測量儀 的潤滑劑的供給狀態監視裝置的情況，藉由測定歪曲測量 儀的絕緣電阻便可確認歪曲測量儀的斷線。另外，藉由靜 歪曲測定可確認歪曲測量儀.是否正常。 另外，本發明不僅限於應用於潤滑脂等的潤滑劑供給軸 39 326\專利說明書(補件)\93-03\93100876 1271486 承等用的自動供給裝置，還可應用於手動供給裝置。 (產業上的可利用性） 根據本發明，可在各潤滑部位附近確實監視供給潤滑部 位的潤滑劑的供給狀態，且可廉價構成，因此可應用於旋 轉機械的軸承等的需要潤滑劑的各個部位。本發明可迅速 發現潤滑劑不良，而防範故障於未然。

[Prior Art] The amount of production equipment provided in a factory or the like is used at a certain time interval. One of the main reasons for the automatic centralized lubrication of bearings for bearings, such as lubrication, is that the operation of supplying each device is very important. As a method of monitoring automatic centralized lubrication, it is known that it is used to operate with a certain valve and count for a specified time. The supply of the lubricant is appropriately performed. However, in this method, since the supply state of the lubricant is not obtained, the supply of the lubricant to the lubricant is not good. In another method, the supply state of the lubricant supply pipe to each of the lubrication parts in which the supply state of the machine parts is supplied is confirmed. Each of the lubricants measured by the pressure sensor is provided with a predetermined set pressure, which is based on a lubrication device such as a mechanical bearing. A large number of rotating machines are used. Lubricant is supplied to the rotary unit, such as large grease. The equipment of the rotating machine is abnormal. Therefore, it is possible to check the number of operations of the distribution valve when the supply state time interval of the lubricant of the lubricant 〇 device is supplied, and to confirm that the passage behind the distribution valve is known, and it is impossible to monitor the damage from the distribution valve to the bearing tube. In the lubrication method of the bearing or the like caused by clogging or the like, the pressure sensor attached to the bearing is used to confirm the lubrication method. The controller compares the pressure and the result of the lubricant in the pipe by the controller. It is determined that the lubricant is not supplied with an abnormality of the pressure sensor or the pressure sensor, and an alarm is issued, for example, as disclosed in Patent Document 1 (for example, Patent Document 1). However, in the method using such a pressure sensor, it is necessary to mount a pressure sensor power supply pressure sensor to each lubricant supply pipe of each lubrication portion. Therefore, in the case where it is desired to form a monitoring point of thousands of parts in a production plant or the like in a pressure-sensing manner, the monitoring device becomes expensive, and the installation cost becomes expensive, and as another method, The piezoelectric element is placed in a state in which the lubricant path is connected, and the pulsation in the flow path is pressed against the piezoelectric element, and the charge obtained by the piezoelectric effect is transformed to detect the supply state of the lubricant. For the purpose of knowing (example 2). However, in the method of applying the pulsating pressure of the lubricant to the piezoelectric element in a state in which such a diameter is connected, it is difficult to obtain a sufficiently large size because the practical supply of the lubricant supply state cannot be obtained, and thus the lack of correctness is caused.

Top member. The method for monitoring the supply state of the lubricant of the present invention is characterized in that a distortion measuring instrument is used. [Embodiment] Fig. 1 is a cross-sectional view showing the configuration of a lubricant sensor according to an embodiment of the present invention. The lubricant supply state monitoring sensor 1 has a T-shaped pipe joint 2 2 b that is configured to supply an oil-like or grease-like lubricant (for example, grease) to a lubricant supply pipe of a rotating machine or the like, and is connected. Threaded socket 3. On the other side of the nipple 3, the socket 5 of the plug 4 is inserted. Further, the plate-shaped detecting member 6 of the component (Pie ζ 〇 element) 8 is inserted into the T-shape from the opening of the plug 4, and the plug 4 and the socket 5 are screwed and fixed, and the screw socket 5 and the joint are provided. The portions 2b are also screwed together. The main pipe portion 2a of the T-shaped pipe joint 2 is connected to a lubrication pipe (not shown) and has a function as a lubricant circulation portion. Further, the upper portion 2b extends perpendicularly from the center of the main pipe portion 2a, and the joint detecting member 6 is inserted into the fitting portion 15 by the joint groove 3, the plug 4, and the socket 5. Further, in addition to the T-shaped pipe joint 2, a joint of a Y-shaped pipe joint or a cross pipe joint may be used, but it is preferable to use a T-shaped pipe joint 2 from the viewpoint of constitution. Further, the nipple 3 and the socket 5 are provided for the purpose of adjusting the length of the detecting member insertion portion 15 corresponding to the detecting member 6, since the 326\patent specification (supplement)\93-03\93100876 14 is : Sensing to state monitoring. At the joint of the mechanical bearing, the soap is then inserted into the piezoelectric joint; The nozzle 3, the lubricant supply, the joint portion 2b, and the detection structure of the screw are installed. The length of the plug is easy to test. This is not a necessary configuration for the 1271486. However, as the subsequent description of the sensitivity of the detecting member 6, it is necessary to have some preferable setting. The upper end of the detecting member 6 is made of the upper portion of the resin 7, whereby the lubricant can be prevented from passing from the lower end of the T-shaped detecting member 6 to the main portion 2a of the function of the flow-receiving portion in an unrestricted state. According to this, in the main pipe portion 2a, the lubricant element is bent and deformed at the detection position, and the piezoelectric element 8 generates a voltage due to the bending. As shown in the longitudinal cross-sectional view of Fig. 2, the detecting member is formed into an elongated gusset-shaped piezoelectric element 8. The flexible covering material 10 is covered with the entire structure; the piezoelectric element 8 is provided with ends on both sides thereof. The pole is connected by a solder or the like for taking out the wire 11 which is pressed. That is to say, in the case where the distortion is caused by the application of the piezoelectric element 8, the piezoelectric element 8 can be bent, that is, deformed to generate a voltage, and can be a one-piece type, or When the piezoelectric element is bent by the force F by bonding two piezoelectric elements, one element shrinks and both of the elements generate electric charges, and the piezoelectric element 8 may be bonded to three or more pieces. The material constituting the piezoelectric element 8 is only 326\patent specification (supplement)\93-03\93100876 15 , and in order to obtain a good degree of sensing, the 接头 joint 2 of the fixed plug 4 is leaked. Further, the lower end of the flow-through member 6 is supplied as a lubricant, and the lower end of the flow-through member 6 is deformed to induce electric charge. 6 has two faces sandwiched by the reinforcing plate 9, and further has a measurable electrode at the end of the electric component 8 The resulting bending stress of the electric slip stream is made; • A voltage is generated across the wire. A double variant consisting of a single change consisting of each curved piezoelectric element as described above. The two components stretch and the other side gives a larger output. The material of the plate-shaped piezoelectric element is 1271486, and it is preferably a piezoelectric ceramic or a piezoelectric piezoelectric film. Among these, piezoelectric ceramics having a large output voltage are preferable. Further, the shape of the piezoelectric element 8 may be a rod shape or a shape similar to a groove shape in which the tube is cut into half, as long as it can withstand the bending of the lubricant flow, but the operation is considered. Convenience and manufacturing cost are preferably elongated cuboid shapes. The reinforcing plate 9 is provided so as not to cause damage to the piezoelectric element 8 due to bending stress. The material of the piezoelectric element 8 may be prevented from being damaged by the specified bending stress. If it is insulated from the piezoelectric element 8, it may be a metal such as iron or a polymer material such as plastic. Further, the reinforcing plate 9 may be provided on both surfaces of the piezoelectric element 8, or may be provided on one side. Further, the covering material 10 is used to protect the piezoelectric element 8 and the reinforcing plate 9 in an integrated manner, and when the piezoelectric element 8 is broken, it is possible to prevent the damaged piece from being mixed into the lubricant to cause an abnormality of the device. The covering material 10 is particularly effective in the case where the piezoelectric element 8 is formed of a brittle ceramic. The material of the covering material 10 is preferably a resin material as long as it has a sufficient protective function for flexibility. For example, a heat shrinkable film is preferably used. The reinforcing plate 9 and the covering material 10 may have a multilayer structure depending on the material of the piezoelectric element 8, the use conditions, and the like. Further, the reinforcing plate 9 and the covering material 10 are not necessarily required, and the detecting member 6 may be formed by directly covering the piezoelectric element 8 with the covering material 10 without using the reinforcing plate 9, or the piezoelectric plate may be sandwiched by the reinforcing plate 9 The element 8 is directly used as the detecting member 6. Further, if the piezoelectric element 8 has sufficient strength or toughness, the detecting member 6 may be separately constituted by the piezoelectric element 8. However, it is preferable that the covering material 10 has a function of enhancing the moisture-proof and electrical insulation of the piezoelectric element 8. 16 326\Patent Specification (Repair)\93-03\93100876 1271486 FIG. 3 is a view showing an example of a configuration in which the supply state monitoring sensor 1 of the above-described lubricant is incorporated in a lubricant supply circuit. The supply state monitoring sensor 1 of the lubricant is a part of a lubricant supply circuit composed of an automatic centralized lubrication device that supplies lubricant at regular intervals. Specifically, it is provided in the middle of the lubricant supply pipe 13 branched from the distribution valve 12. In order to monitor the supply of the lubricant to the lubrication site, it is preferable to install it in the vicinity of the bearing 14 of the lubrication portion or the bearing 14 itself. In the supply state monitoring sensor of the lubricant having the above configuration, when the lubricant is supplied to the lubrication portion through the lubricant supply pipe 13, the arrow shown in FIG. 1 is generated in the main pipe portion 2a of the T-shaped pipe joint 2. Directional lubricant flow. Then, the detecting member 6 is bent in the downstream direction of the lubricant flow with the portion fixed by the resin 7 as a fulcrum. As a result, opposite charges are generated on the front and back surfaces of the piezoelectric element 8, and a voltage is generated at both ends of the wire 11. Therefore, by detecting the voltage, the supply state of the lubricant can be grasped. Figure 4 shows the output waveform at this time. The vertical axis of Fig. 4 indicates the voltage generated in the wire 11, and the horizontal axis indicates the elapsed time. As shown in Fig. 4, when a intermittent lubricant pressure feed flow acts on the detecting member 6 to cause bending, a pulse-like voltage 17 is generated. Then, when the lubricant flow is stopped, the detecting member 6 is returned to the original state by the elastic force of the piezoelectric element 8 and the reinforcing plate 9. At this time, the added distortion is reduced, and as a result, a pulse-like voltage 18 having an opposite polarity is generated. Thus, a voltage pulse forming a positive and negative pair is generated by the intermittent lubricant flow, and as shown in Fig. 4, a waveform with less noise can be obtained. Accordingly, the longer the length of the detecting member 17 326\patent specification (supplement) \93-03\93100876 1271486 6 is, the larger the distortion becomes, so that a larger generated voltage can be obtained. In the supply state monitoring sensor of the lubricant according to the present embodiment, the piezoelectric element 8 is designed based on the above principle. Therefore, it is not necessary to perform special signal processing when the generated voltage is large. The level of amplification processing and noise removal processing. Further, since the piezoelectric element 8 is used, the supply state of the lubricant that does not use the power source can be grasped. According to this, the supply state monitoring sensor of the lubricant can be made small and inexpensive. Further, according to this principle, the larger the amount of the lubricant flowing, the larger the distortion of the detecting member 6, and therefore the peak value of the generated voltage 17 is also increased. Accordingly, a sufficient amount of the lubricant can be supplied when the voltage 17 is equal to or greater than a certain value. Conversely, if the voltage 17 is equal to or smaller than a certain value, it can be determined that the amount of the supplied lubricant is insufficient. Further, in this manner, the upper end of the detecting member 6 having the piezoelectric element 8 is fixed, and the lower end is placed at a position in the lubricant flow formed when the lubricant is supplied, so that the lubricant flows to the lower end. In the manner in which the displacement is deformed and the bending is deformed, the piezoelectric element 8 is electrically contracted by the bending deformation. Therefore, in comparison with the case of detecting the pulsating pressure of the lubricant as in the above-mentioned Patent Document 2, an essentially large output can be obtained. The supply state of the lubricant can be reliably monitored in the vicinity of each lubrication portion. Hereinafter, an experiment for confirming such an effect will be described. A grease supply device as a lubricant as shown in FIG. 5A is prepared, and a supply state monitoring sensor of the lubricant of the embodiment shown in FIG. 1 is mounted as shown in the drawing, and the configuration shown in FIG. The supply state of the lubricant of the comparative example monitors the sensor. That is to say, the supply state monitoring of the embodiment 18 326\patent specification (supplement)\93-03\93100876 1271486 The sensor is vertically mounted to the τ-type pipe joint in the state of holding the detecting member with one hand (1 / (4) The sensor of the comparative state of the present invention is a sensor that simulates the above-mentioned Patent Document 2 (Japanese Patent Laid-Open Publication No. Hei No. Hei No. Hei No. Hei. The status level is installed in the Τ type pipe joint (1 / 4 Β ). As the piezoelectric element constituting the detecting member, an I too acid-wound S-boat ceramic of 5 mm X 60 mm X 0 · 5 mm is used, and a heat-shrinkable film (trade name: SUM I TUBE) is coated thereon as a piezoelectric element. Detection of components. The supply of the lubricant which is a lubricant is carried out intermittently using a van der pump (i a r v a 1 p u m p ). Figure 6 shows the voltage detection state at this time. As shown in the figure, relative. In the case of the comparative example, a pulse of at most several mV can be obtained by the supply of the grease, and in the case of the present embodiment, a pulse exceeding 20 mV can be obtained. From this, it was confirmed that the configuration of the present invention can more reliably monitor the supply state of the lubricant. Next, the configuration of the monitoring device for monitoring the supply state of the lubricant using the supply state of the lubricant described above will be described. Fig. 7 is a view showing the configuration of a supply state monitoring device for a lubricant according to the first embodiment. In the supply state monitoring device for the lubricant according to the first embodiment, the monitoring device 1 is provided with the counting device 25 in the supply state of the lubricant, and the wire 1 1 of the sensor 1 is monitored for the supply state of the connected lubricant. It is composed of the input terminals of the counting device 2 5 . In the process of generating the lubricant flow, the lubricant flow is detected by the detecting member 6, and the number of times the lubricant is supplied is counted by the counting device 25 and displayed. Here, the initial count of the counting device 25 is recorded in advance, and after a certain period of time 19 326\patent specification (supplement)\93-03\93100876 1271486, the count displayed by the counting device 25 is confirmed by The subtraction method calculates the number of times the lubricant is supplied during the predetermined period of time. Therefore, in the case of not counting, the lubricant is not supplied or the supply amount is small. Accordingly, by comparing the calculated number of times and the number of times the lubricant is supplied in a predetermined period of time, it is possible to determine whether or not the lubricant is normally supplied. Since the piezoelectric element 8 is used as the detecting member 6, it is necessary to The power supply for supplying power to the detecting member 6 is only required to supply power to the counter device 25. Therefore, the entire device can be made smaller and cheaper by using a battery or the like in the counting device 25. Fig. 8 is a configuration diagram showing another embodiment of the supply state monitoring device for the lubricant. In the apparatus of the present embodiment, the supply state sensor 1 of the lubricant is provided with the counting device 25, the timing device 26, and the alarm device using the number of times the lubricant is counted by the counting device 25 and the time of the device 26. The information is determined by an arithmetic device (not shown) to supply the lubricant for a predetermined period of time. If the lubrication is not supplied for a predetermined period of time or the supply amount is small, the alarm device 27 issues an alarm. In the present embodiment, the lubricant can be monitored by a small device and an alarm can be issued. Therefore, the counting means 25 and the timing means 26 can be formed integrally, or the signal lines can be separated by separating them. Further, the alarm device 27 can issue an alarm by light, sound, or the like: it is also possible to indicate the police by mechanical switching not only by the electronic display. Fig. 9 is a still further embodiment of the monitoring device for supplying the lubricant. 326\Patent specification (supplement)\93-03\93100876 20 The availability of the situation is not in the case of small form monitoring 27 « t The composition of the finger is not available for the police connection, and the composition of the form 1271486 is reported. In the apparatus of the present embodiment, the supply state of the lubricant is monitored by the sensor 1, the counting device 25, the alarm device 27, and the distribution valve displacement sensor 28. The distribution valve displacement sensor 28 detects the operation of the distribution valve 12, and takes in the timing at which the distribution valve 12 is actuated as the supply timing of the lubricant. Then, from the start of the operation of the distribution valve 12, the count of the counter device 25 is not increased for a predetermined period of time, and it is determined that the supply of the lubricant is defective, and the alarm device 27 issues an alarm. In the apparatus of the present embodiment, the distribution valve displacement sensor 28 is provided in place of the timing device 2 6 of the apparatus of another embodiment, and the displacement of the distribution valve is detected, and the lubrication is monitored when the distribution valve 12 is actuated. The supply status of the agent. Therefore, the abnormality can be quickly detected as compared with the case of using the timing device 26. Fig. 10 is a configuration diagram showing still another embodiment of the supply state monitoring device for the lubricant. The apparatus of the present embodiment is composed of a lubricant supply state monitoring sensor 1, a counter device 25, an alarm device 27, and a lubricant supply pump start signal 29. When the lubricant supply pump start signal 2 9 is turned on (ON) and the count of the counter device 25 is not increased within a predetermined time, it is determined that the supply of the lubricant is poor, and the alarm device 27 issues an alarm. In the apparatus of the present embodiment, the lubricant supply pump start signal 2 is provided instead of the timing device 2 6 of the apparatus of another embodiment to detect the conduction of the lubricant supply pump start signal 29 to monitor the supply state of the lubricant. . Therefore, the abnormality can be quickly detected as compared with the case of using the timing device 26. Fig. 11 is a configuration diagram showing still another embodiment of the supply state monitoring device for the lubricant 21 3% \ patent specification (supplement) \93-03\93100876 1271486. The apparatus of the present embodiment is a device in which the wireless device 30 and the data collecting device 31 are installed in the apparatus of the first or another embodiment. In the apparatus of the present embodiment, it is possible to collect information on the supply state of the lubricant and monitor it even in a device that cannot be easily accessed in the operating state of the apparatus due to a safety problem or the like. The data collected in this case may be a count value or a determination result of the supply state of the lubricant. Fig. 12 is a configuration diagram showing still another embodiment of the supply state monitoring device for the lubricant. The apparatus of the present embodiment is configured as a line monitoring system (Ο η 1 i n e m ο n i t 〇 r i n g s y s t e m ). The supply state monitoring sensor 1 of the lubricant is connected to the counting device 25 and the data collection monitoring device 35 via the wire 11 and further relates the lubricant to a wired, wireless, telephone line, LAN, or the like (not shown). The data of the supply status is transmitted to the personal computer 36. With this configuration, especially with respect to important equipment, the supply state of the lubricant can be constantly monitored in a long distance. Further, the line monitoring system is not limited to the embodiment shown in FIG. 12, and may be configured in combination with the above-described embodiment, and includes a data collection and monitoring device 35 and a personal computer 36, and may be used as the data collection and monitoring device 3. 5 to monitor the data generated by the various embodiments. Further, the output signal of the supply state monitoring sensor 1 of the lubricant can be directly connected to the data collection monitoring device 35. In the supply state monitoring device for a lubricant according to each of the above-described embodiments, the sensor 1 is monitored by the supply state of the lubricant provided in the lubrication portion or the lubricant supply pipe, and the state of the supplied lubricant is monitored. More than a certain amount of lubricant. By monitoring the supply state of the lubricant 22 326\patent specification (supplement)\93-03\93100876 1271486, the sensor 1 is combined with each component and device as needed in the above embodiments. The device can form a sufficient device configuration necessary for monitoring the supply state of the lubricant in various functions and various applications. Therefore, the lubricant supply state in the vicinity of the lubrication portion or the lubrication portion can be monitored, and the initial abnormality due to the supply failure of the lubricant can be prevented. Further, the present invention is not limited to the above embodiment, and various changes can be made. For example, in the above embodiment, grease is exemplified as the lubricant, but various oily or grease-like lubricants such as lubricating oil may be used. Further, in the above embodiment, the example in which the apparatus of the present invention is applied to the automatic centralized lubrication apparatus has been described, but it can also be applied to a manual lubrication apparatus. As shown in FIG. 13 , it is also possible to directly insert the plug 4 into the upper portion of the T-shaped pipe joint 2, and then insert the detecting member 6 into the inside of the T-shaped pipe joint 2 from the opening provided in the plug 4, and the plug 4 is inserted by the resin 7. The upper portion is solidified to fix the one-side end of the detecting member 6 while preventing the leakage of the lubricant from the T-shaped pipe joint 2. Further, as shown in FIG. 14, a joint of the nipple 3 into which the plug 4 is inserted may be connected to the joint of the T-shaped joint 2, and the detecting member 6 may be inserted into the T-shaped joint 2 from the opening provided in the plug 4. Internally, the upper portion of the plug 4 is solidified by the resin 7 to fix the one-side end of the detecting member 6 while preventing the leakage of the lubricant from the T-shaped pipe joint 2. Fig. 15 is a view showing an example of a configuration in which a supply state monitoring sensor of a lubricant is incorporated in a lubricant supply circuit. The lubricant supply state monitoring sensor 1 is a lubricant supply circuit composed of an automatic centralized lubrication device that supplies lubricant at intervals of 23 326\patent specification (supplement)\93-03\93100876 1271486. a part of. Specifically, it is provided in the middle of the lubricant supply pipe 1 branched from the distribution valve 12, but in order to monitor that the lubricant is supplied to the lubrication portion, it is preferable to be attached to the pole of the bearing 14 of the lubrication portion. Near or bearing 1 4 itself. However, in the environment where the equipment is installed, it is also difficult to provide it in the vicinity of the bearing 14. At this time, as shown in Fig. 16, it is preferable to set the place where the supply state of the lubricant is monitored and the damage of the sensor 1 is small. Fig. 17 is a cross-sectional view schematically showing the configuration of a supply state monitoring sensor of a lubricant according to another embodiment of the present invention. In the supply state monitoring sensor of the lubricant according to the first embodiment, the Y-type pipe joint 2 1 is used instead of the T-shaped pipe joint 2 in the supply state and monitoring sensor of the lubricant of the first embodiment. Composition. In the present embodiment, since the height of the supply state monitoring sensor of the lubricant can be suppressed to be low, there is an advantage that it can be applied to a narrow place where interference with other devices, machines, and the like is performed. Fig. 18 is a cross-sectional view schematically showing the configuration of a supply state monitoring sensor of a lubricant according to still another embodiment of the present invention. In the supply state monitoring sensor of the lubricant of the first embodiment, the cross-type pipe joint 2 2 is used instead of the T-shaped pipe joint 2 in the supply state monitoring sensor of the first embodiment. . Then, the plugs 4 are respectively inserted into the ends of the two portions of the cross-shaped pipe joint 2 2 perpendicular to the flow direction, and the plate-shaped detecting members 6 having the sensing elements are inserted into the cross-shaped tubes from the openings provided in one plug 4. The connector 2 2 is supported by the plugs 4 at both ends 326\patent specification (supplement)\93-03\93100876 24 1271486. In the present embodiment, the detecting member 6 is provided to penetrate the lubricant supply pipe 13 and the structure of the detecting member 6 is held from both sides. Therefore, the height of the single side can be made low. Fig. 19 is a cross-sectional view schematically showing the configuration of a supply state monitoring sensor of a lubricant according to still another embodiment of the present invention. In the supply state monitoring sensor of the lubricant according to the first embodiment, the elbow type pipe joint 23 is used instead of the T-type pipe joint 2 in the supply state monitoring sensor of the first embodiment. Composition. In the present embodiment, the supply state monitoring sensor of the lubricant can be applied to the portion of the lubricant supply pipe 13 in the direction of the lubricant flow. Further, in the present embodiment, the lubricant flow is detected with good sensitivity, and it is preferable that the detecting member 6 is disposed at a position near the outlet of the upstream lubricant supply pipe 13 . In addition, the pipe joint can be used in addition to the elbow type pipe joint 2 3 . Here, the angle of the elbow joint 2 3 and the elbow joint is not limited to 90 degrees, and may be constituted by an arbitrary angle. Fig. 20 is a cross-sectional view showing the configuration of a supply state monitoring sensor of a lubricant according to still another embodiment of the present invention. The supply state monitoring sensor of the lubricant according to the other embodiment has the same configuration as that of the first embodiment, but the detecting member 6 is different from the piezoelectric element 8 in that a distortion detecting element is used. Fig. 21 is a cross-sectional view seen from the side of the configuration of the display detecting member 6. The detecting member 6 uses the distortion measuring instrument 16 as a distortion detecting element, 25 326\patent specification (supplement)\93-03\93100876 1271486, and the bending measuring instrument is adhered to the reinforcing plate 9 and then covered by the elastic force. The material 10 is covered with the entire structure. Then, the wire 11 is connected to the electrode provided at the end of the distortion measuring instrument 16 by soldering or the like. Here, the reinforcing plate 9 may be a material which is distorted to a predetermined bending stress, and may be a metal such as iron or a polymer material such as plastic. In addition, the installation of the distortion measuring instrument 16 is adhered not only to one side of the reinforcing plate 9, but also to both sides. Further, a configuration in which a dummy measuring instrument (d m m m y g a u g e ) is used to compensate for a temperature change may be employed, and a configuration using a known various methods as a general measuring method may be employed. In the same manner, when the lubricant is supplied to the supply state of the lubricant connected to the lubricant supply pipe 13 to monitor the sensor, a lubricant flow in the direction of the arrow shown in Fig. 20 is generated. Then, the detecting member 6 bends the downstream portion of the lubricant flow by using the portion fixed by the resin 7 as a fulcrum. As a result, the reference line of the distortion measuring instrument 16 is deformed to change the resistance value. The change in the resistance value is detected by a Wheatstone bridge (not shown) as a voltage change to measure the amount of distortion. Fig. 2 2 is a diagram showing the output waveform of the supply state monitoring sensor using the lubricant of the distortion detecting element. The vertical axis represents the amount of distortion, and the horizontal axis represents the time elapsed from left to right. By the distortion caused by the intermittent lubricant flow in three times acting on the detecting member 6, three mountain-shaped distortion amounts waveforms of 19 a, 1 9 b, and 19 c can be obtained. Then, when the lubricant flow is stopped, the detecting member 6 is returned to the original state by the elastic force of the reinforcing plate 9. As a result, the amount of distortion is restored toward the original state. Thus, the mountain shape of the 26 326 \ patent specification (supplement) \93-03\93100876 1271486 distortion waveform is obtained by intermittent lubricant flow, and the waveform becomes a waveform with less noise. Here, in the waveform of FIG. 2, the waveform of the continuous mountain-shaped distortion amount takes time until the original state is restored by the elastic force of the reinforcing plate 9, and therefore, if the material having a higher elastic force is selected as the reinforcing plate 9, This phenomenon cannot be produced. However, this phenomenon is not a problem in the case of applying an automatic centralized lubrication device that supplies lubricant every few hours. Further, as a disadvantage of the distortion measuring instrument 16, a shift of the zero point of the lubricant in the case of temperature change can be cited, but it can be solved by the above-described application of temperature compensation or signal processing using a high-pass filter. . Further, the supply state monitoring sensor of the lubricant is a simple configuration in which only the distortion measuring instrument 16 is used in the detecting member 6. Therefore, when compared with the case where a pressure sensor is applied, a small-sized, inexpensive lubricant supply state monitoring sensor can be obtained. Next, a configuration of a supply state monitoring device for a lubricant that counts the number of times the lubricant is supplied and determines the function of the supply state of the lubricant is provided. Fig. 7 is a view showing the configuration of a supply state monitoring device for a lubricant according to the first embodiment. As a variation of this embodiment, the counting device 25 can be directly joined to the T-tube connector 2 by using the supply state monitoring sensor shown in Fig. 13 . 23A, 23B, and 23C are cross-sectional views schematically showing the configuration of a supply state monitoring device for a lubricant according to another embodiment of the present invention. Fig. 2 3 A, Fig. 2 3 B and Fig. 2 3 C lubricant supply state monitoring device, in the lubricant supply state monitoring device of Fig. 7, the counting device 27 326\patent specification (supplement) \93-03\93100876 1271486 2 5 Set to a rotatable configuration. That is, in Fig. 2 3 A, the length direction of the detecting member 6 is taken as a central axis, and the counting device 25 is configured to be rotatable about the central axis. Further, Fig. 23B is configured such that the detecting member 6 is perpendicular to the direction of the surface subjected to the dynamic pressure of the lubricant as a central axis, and the counting device 25 is configured to be rotatable about the central axis. Further, Fig. 2 3 C is configured to be rotatable about the two central axes of Fig. 23A and Fig. 2B. According to this embodiment, the counting device 25 can be rotated at an appropriate angle regardless of the state in which the lubricant supply state monitoring device is provided. Therefore, the counter value can be easily read without changing the posture of the reader. Fig. 24 is a cross-sectional view showing still another embodiment of the supply state monitoring device for a lubricant of the present invention. The supply state monitoring device of the lubricant of Fig. 24 is the supply state monitoring device for the lubricant of Fig. 7, and the counting device 25 is detachably formed in the T-shaped pipe joint 2 or the nipple 3 by the wire 1 1 is connected to the detecting member 6 and the counting device 25. Since the counting device 25 is detachably constructed, the counting device 25 is provided with a clamping mechanism or a suction mechanism. Fig. 2 5A and Fig. 2 5B are diagrams showing a state in which the counting device 25 is attached to the lubricant supply pipe 13. Figure 2 5 A shows the front view of the installation state, Figure 2 5 B shows a sectional view of the installation state. The counting device 25 can be attached to the lubricant supply pipe 13 by the clamp mechanism 34.

The same components as those in Fig. 3 are denoted by the same reference numerals, and detailed description thereof will be omitted. The counting device 25 of Fig. 35 differs from the previous embodiment in that a data wireless transmitting unit 47 is provided in addition to the configuration of the counting device 25 of Fig. 32. The data wireless transmitting unit 47 transmits at least one of the count value, the determination result of the supply state of the lubricant, and the alarm output to the data wireless receiving device 48. The transmission timing can be a specified period, or can be sent when an external data transmission request is received. According to the supply state monitoring device of the lubricant of Fig. 35, the equipment that cannot be easily accessed in the operating state of the equipment due to a safety problem or the like can be monitored by collecting information on the supply state of the lubricant. 33 326 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 The same components as those in Fig. 3 are denoted by the same reference numerals, and detailed description thereof will be omitted. The counting device 25 of Fig. 36 differs from the previous embodiment in that a data collecting unit 50 is additionally provided in addition to the configuration of the counting device 25 of Fig. 3 . The supply state monitoring device of the lubricant of Fig. 3 is used as a production line monitoring system. In other words, the data collection unit 50 transmits the data on the supply state of the lubricant to the material management system 51 by using a communication line such as a wired line, a wireless line, a telephone line, or a L A N. According to this configuration, particularly with respect to important equipment, it is possible to constantly monitor the supply state of the lubricant from a long distance. Further, the line monitoring is not limited to the embodiment shown in Fig. 36, and the embodiment described so far may be combined, and the data generated in each embodiment may be transmitted to the material management system 5 1 through the data collecting unit 50. Monitor. Further, the alarm unit 43 can use various configurations. For example, when an alarm is issued by light, a light-emitting diode may be provided in the supply state monitoring device of the lubricant to form a configuration in which the indoor signal lamp blinks at a remote location. Further, in the case where an alarm is issued by the sound, the speaker may be provided in the lubricant supply state monitoring device, and the alarm sound and sound may be output through a separate alarm device in a remote place where the cab or the security is deployed. Further, in the case where an alarm is displayed, it is possible to display the alarm not only by the display of the electronic display, but also by the mechanical display.

Further, as shown in Fig. 3A, a flat plate 5, which is divided into normal and abnormal colors by color separation, may be provided on the counter device 25, and the spring 5 8 abuts against the pin 5 9, when an abnormality occurs, such as As shown in Fig. 3 8B, the flat plate 57 is moved by the release pin 5 9 and the supply state of the lubricant is displayed from the alarm display window 56. Further, after the alarm is displayed, the display state is restored by the press-in lever 60. When the supply state monitoring device for the lubricant of each of the above-described embodiments is used, it is possible to monitor whether or not a necessary amount of lubricant is supplied to a device such as a rotary machine in various states. Further, by combining the components and devices of the above-described embodiments as needed to form the supply state monitoring device for the lubricant, it is possible to construct a supply state monitoring device for the lubricant having a new function. Therefore, the supply state monitoring device for the lubricant can be configured with necessary and sufficient functions, and the initial abnormality caused by the poor supply of the lubricant of various devices can be prevented. Further, the supply state monitoring device for a lubricant of the present invention can be applied not only to grease but also to lubricants such as oils. Further, since the above embodiment includes various stages of the invention, various kinds of inventions can be extracted by a suitable combination of the plurality of constituent elements disclosed. For example, even if a plurality of constituent elements are removed from the entire constituent elements disclosed in the embodiments, the problems stated in the part of the problem to be solved by the invention and the effects stated in the effect of the invention can be obtained. The configuration in which the constituent elements are removed is extracted as an invention. 35 326\Patent Specification (Supplement)\93-03\93100876 1271486 Fig. 3 is a graph showing an embodiment of a method of monitoring a supply state of a lubricant according to the present invention. In the present embodiment, when the number of times of supply of the lubricant to be counted is lower than the supply timing of the lubricant for a predetermined time set in advance, it is determined that the supply state of the lubricant is abnormal. In the example of Fig. 39, the supply time of the lubricant in the predetermined time period is 1 time / 2 hours (5 times / 10 hours), and the supply state of the lubricant is 1 time / 2 hours in 40 hours. (5 times / 10 hours) the number of normal lubricants supplied, but at 40 to 50 hours, the number of times the lubricant is supplied is reduced to 〇/hour, and once again at 50 to 60 hours. The number of normal lubricants supplied for 2 hours. Although the number of times the lubricant is supplied is lower than the predetermined number of times of supply of the lubricant in the predetermined time period from 40 to 60 hours, this is because the machine that has to supply the lubrication is stopped due to the stop of the production line. In addition, the number of times of supply of the normal lubricant for one time/two hours is continued again at 60 to 70 hours, but the number of times of supply of the lubricant is lower than the predetermined time within 80 hours, so that the lubricant is determined. The supply status is abnormal. Fig. 40 is a graph showing the change in the number of supply times of the lubricant for each specified time shown in Fig. 39 and the change in the number of times the lubricant is supplied. The supply state of the lubricant can also be monitored in Fig. 40 as well as in Fig. 39. In other words, in Fig. 40, the curve becomes a straight line with a certain slope (the number of times of supply of lubricant/specified time) in 0 to 40 hours, and a lubricant supply is required at 40 to 50 hours. When the machine is stopped due to the stop of the production line, the curve temporarily becomes level. Then, within 50 to 70 hours, it becomes a line with 36 326\patent specification (supplement)\93-03\93100876 1271486 with the same slope as 0 to 40 hours, but starting from 80 hours The slope is lowered, and it is determined that the supply state of the lubricant is abnormal. Fig. 4 is a view showing another example of the supply state monitoring method of the lubricant of the present invention, showing an example of a change in peak voltage of the sensor output measured by a device capable of performing peak synchronization processing with respect to time. The peak voltage of the sensor output can be easily obtained by inputting the sensor output waveform to an oscilloscope or other analysis device with peak synchronization processing. In the present embodiment, the waveform is output from the sensor, and the peak voltage output from the sensor is measured by the peak synchronization processing. When the peak voltage is outside the predetermined range, it is determined that the supply state of the lubricant is abnormal. Specifically, the lower limit threshold and the upper limit threshold may be set in advance in the peak voltage, and when the peak voltage is less than the lower limit threshold, it is determined that the supply amount of the lubricant is decreased or stopped, and the peak voltage exceeds the upper limit. When the limit value is reached, it is judged that the jam is generated on the downstream side of the sensor. In the example of Fig. 41, the lower limit threshold value of the peak voltage set based on the initial voltage measured in advance is 0. 1 5 V, the upper limit is 0. 4V. The method of setting the lower limit threshold and the upper limit threshold of the peak voltage, in the case of suppressing the sampling period of the data to a lower value, it is preferable to consider the possibility of occurrence of an error more or less in the peak synchronization processing. Make settings. Here, in Fig. 41, the supply state of the lubricant is within 30 hours, and its peak voltage is zero. 2 V normal supply of lubricant, but at 40 hours, the peak voltage is below the lower limit of 0. 1 5 V and become 0. 1 V, therefore, it is determined that the supply state of the lubricant is insufficient supply. Then, at 4 0~6 0 hours, continue the peak voltage to 0. 1 V status. At 70 hours, 37 3%\patent specification (supplement)\93-03\93100876 1271486 Since the peak voltage is further lowered and the peak voltage becomes zero, it is judged that the supply state of the lubricant is no supply. However, during the 90 hours, the peak voltage rises sharply, exceeding the upper limit threshold of 0. 4 V and become 0. 5 V, so it is judged to be blocked on the downstream side of the sensor. This is because if the clogging on the downstream side of the sensor occurs, the pressure of the sensor portion rises, and the peak voltage also becomes high in order to apply a large force to the piezoelectric element or to distort the measuring instrument. Further, the peak synchronization processing is not performed, and there is a case where a slight error is included, and the supply voltage of the lubricant can be easily determined by visually measuring the peak-to-peak voltage on the surface of the oscilloscope. For example, FIG. 42 is an explanatory diagram showing a kneading output of an output waveform of a sensor directly observed using an oscilloscope. From the left to the right of FIG. 4, it can be determined that the normal lubricant supply state and the supply of the lubricant are insufficient. No supply, no clogging on the downstream side of the sensor. Moreover, Fig. 4 2 is a test result of supplying the lubricant to each state at intervals of 1 second every 5 seconds. As shown in Fig. 1, Fig. 13, and Fig. 14, Fig. 43B is a sensor unit 6 for taking out a supply state monitoring device for using a piezoelectric element for a lubricant of a sensor, and Fig. 4 is a portion from the front end. The piezoelectric element shown in 3 A was cut into 10 μm each, and the electrostatic capacitance of the sensor was cut from Omm (uncut) to 50 mm by an electrostatic capacitance measuring device. According to Fig. 4 3 B, the electrostatic capacity is 1 5 3 0 0 p F when the sensor is not completely cut off (initial value), and when the sensor is cut off 10 mm from the front end thereof, The electrostatic capacity becomes 1 3 2 0 0 p F, and finally, when it is cut off from the front end by 50 m in , it is greatly reduced to 2,900 pF. That is, it is understood that the length of the piezoelectric element is approximately proportional to the magnitude of the electrostatic capacitance. 38 326\Patent specification (supplement)\93-03\93100876 1271486 In general, the abnormality of the sensor using the piezoelectric element is almost caused by the bending stress of the lubricant due to the vicinity of the fixed portion of the sensor. In the case of damage, the capacitance of the sensor is greatly reduced when the capacitance of the sensor is measured. Therefore, the determination of the damage of the sensor fixing portion is facilitated. Therefore, in the present invention, after the monitoring of the supply state of the lubricant is started, if the abnormality is found by the example shown in FIGS. 39 to 24, the electrostatic capacitance of the sensor is measured, which is larger than the preset threshold. When the value is decreased, it is determined that the sensor is abnormal, and the sensor-based abnormality can be removed from the abnormality determination based on the count of the number of supply times of the lubricant or the abnormality determination based on the peak voltage. In the example of Figure 4 3 B, consider the case where the sensor has 10 m m breakage from its front end, and set the threshold to 1 2 0 0 0 p F in advance. That is, according to the embodiment of the supply state monitoring method of the lubricant of the present invention shown in the above-mentioned Figs. 39 to 4, it can be determined that the supply state of the lubricant is abnormal, but the experimental result shown in Fig. 43A is obtained. In the case where the piezoelectric element is used as a sensor, by measuring the electrostatic capacity of the sensor, even if the supply state of the lubricant is abnormal in appearance, the count based on the number of times the lubricant is supplied can be corrected. The abnormality determination or the abnormality determination based on the peak voltage, that is, the abnormality based on the sensor abnormality can still be removed from the abnormality determination, which is preferable. On the other hand, in the case where the supply state monitoring device for the lubricant of the distortion measuring instrument is used in the sensor shown in Fig. 20, the disconnection of the distortion measuring instrument can be confirmed by measuring the insulation resistance of the distortion measuring instrument. In addition, the distortion measuring instrument can be confirmed by static measurement. Is it normal? Further, the present invention is not limited to the application of the lubricant supply shaft 39 325 of the grease or the like (patent specification) \93-03\93100876 1271486 for the automatic supply device, and can also be applied to the manual supply device. (Industrial Applicability) According to the present invention, it is possible to reliably monitor the supply state of the lubricant to be supplied to the lubrication portion in the vicinity of each lubrication portion, and it can be configured at a low cost. Therefore, it can be applied to each of the lubricants required for bearings such as rotary machines. Part. The present invention can quickly find that the lubricant is defective and prevent the malfunction from happening.
