【発明の属する技術分野】
本発明は、主として霧化能力自体の監視機能を有する噴霧潤滑装置に関し、更に詳しくは、霧化機構部における霧化性能の良否(吐出油量の安定度)の判断に供することができる有用な噴霧潤滑装置に存する。
【0002】
【従来の技術】
従来、斯かる噴霧潤滑装置としては、例えば、上下レベルスイッチにより管理される加圧油槽を備えている。
【0003】
【発明が解決しようとする課題】
しかしながら、上述した従来の噴霧潤滑装置の加圧油槽にあっては、あくまでも自動給油制御のためのものであり、霧化機構部における霧化性能の良否(吐出油量の安定度)の判断に供されるものではなかった。
【0004】
本発明は、このような従来の問題点に鑑みてなされたもので、霧化性能の良否(吐出油量の安定度)の判断に供されるなど、霧化能力自体の監視機能をも行うことができる有用な噴霧潤滑装置の提供を目的としたものである。
【0005】
【課題を解決するための手段】
上述の如き従来の問題点を解決し、所期の目的を達成するため本発明の要旨とする構成は、噴霧潤滑における加圧油槽と補給用油槽との二槽を備える噴霧潤滑装置において、
補給用油槽より定量油量を加圧油槽に補給する間隔を一定にし、何かの不具合発生により油の消費量が増加した際、加圧油槽内の油面低下を油面位置P 1 で噴霧油量の増加信号を発信し、油の消費量が低下した際は、加圧油槽内の油面上昇を油面位置P 2 で噴霧油量の低下信号として発信する油量信号発信手段を備えてなる噴霧潤滑装置に存する。
【0010】
このように構成される本発明の噴霧潤滑装置は、加圧油槽に供給する油量を少量一定にすること及び油面位置P1 ,P2 の位置を近づけ、霧化機能が正常である場合は、少量一定供給直後の油面位置をこの油面位置P1 ,P2 位置の中間とし、消費量が増加すれば、油面位置が油面位置P1 より低下して信号を発信し、消費油量が減少すれば、油面位置が油面位置P2 より上昇して信号を発信するので、霧化能力自体の監視機能を持つことになる。
【0011】
更に、噴霧潤滑以外の目的であっても、消費液量を管理するシステムとして流用可能であり、単位時間当たりにどれだけの量を使用する機器であるか、使用量の増減を監視し得ることとなる。
【0012】
以下、本発明に係る噴霧潤滑装置の実施の一例を図面を参照しながら説明する。図中Aは、本発明に係る噴霧潤滑装置であり、この噴霧潤滑装置Aは、噴霧潤滑における加圧油槽1及び補給用油槽2と、油面位置P1 及び/又は油面位置P2 を検出する油面検出手段3,3と、前記補給用油槽2より定量油量を加圧油槽に補給する定量油補給手段4と、噴霧油量の低下信号を発信する低下信号発信手段(図示せず)と、噴霧油量の増加信号を発信する油量増加発信手段(図示せず)と、油量信号発信手段 ( 図示せず ) とを備えている。
【0013】
加圧油槽1は、例えば、上位に配設された油滴下監視用のサイトドーム1aと、該サイトドーム1aに内設されたベンチュリ機構1bとを備えている。
【0014】
油面検出手段3,3としては、レベルスイッチが挙げられる。例えば、フロート式、静電容量式(電極棒式)等のレベルスイッチが挙げられるが、予め設定したレベル(油面位置)以上になった時或いはそれ以下になった時に、電気接点を開閉してその制御回路へ電気信号を送る役目をなすものである。
【0015】
更に、定量油補給手段4は、例えば、給油ポンプからなり、補給用油槽2より定量油量を加圧油槽1に補給する際、油面位置P1 のレベルスイッチの油面低下による切り換わり時に定量油量を供給する。
【0016】
また、低下信号発信手段(図示せず)は、このレベルスイッチのON/OFF作動を監視し、ON作動或いはOFF作動が本来の霧化消費時間の0.9〜10倍の規定時間内に繰り返されることを確認すると共に、確認されない場合に、噴霧油量の低下信号として発信するものであり、図2に示すように、油面位置P1 のレベルスイッチの作動A、Bによって、その時点A、Bを新たな規定時間の起点とすべく制御されている。
【0017】
更に、油量増加発信手段(図示せず)は、図3に示すように、本来の霧化消費時間の0.9倍未満の規定時間t内で、油面位置P1 のレベルスイッチの油面低下による切り換わり信号が作動する際(D地点)、噴霧油量の増加信号を発信するものであり、油面位置P1 のレベルスイッチの作動によってその時点を新たな規定時間の起点とすべく制御されている。
【0018】
また、油量信号発信手段は、補給用油槽2より定量油量を加圧油槽1に補給し、何かの不具合発生により油の消費量が増加した際、加圧油槽1内の油面低下を油面位置P1 で噴霧油量の増加信号を発信し、油の消費量が低下した際は、加圧油槽1内の油面上昇を油面位置P2 で噴霧油量の低下信号として発信すべくプログラムされている。
【0019】
例えば、図3に示すように、規定時間t内に、油面位置P1 のレベルスイッチの油面低下による切り換わり信号が作動した際(D地点)、このD地点で多消費の異常信号を発信し、D地点で補給が開始され、再認定される規定時間の原点になる。尚、規定時間マイナスリミットt1 内で再給油されるのは正常と判断され、規定時間プラスリミットt2 時点で小消費の異常信号が発信される。
【0020】
更に、定量油量は、その潤滑対象の要求により、その定量油量の油量を変更できる油量変更手段(図示せず)を備えるのが好ましい。
【0021】
尚、図中5は、エア又はオイル駆動のポンプであり、ルブリケータ1に間欠的に潤滑油を送り込むものである。換言すれば、このポンプ5は、例えば、加圧油槽1と連通されたインジェクションポンプからなり、また、図外の信号検出手段からの信号処理により同インジェクションポンプの作動頻度を増減させることで、フォグの生成量を増減させることもできるものであり、油霧発生器の形式により同ポンプ5の必要性の有無が決定される。
【0022】
このように構成される本実施例の噴霧潤滑装置は、加圧油槽1に供給する油量を少量一定にすること及び油面位置P1 ,P2 の位置を近づけ、霧化機能が正常である場合は、少量一定供給直後の油面位置をこの油面位置P1 ,P2 位置の中間とし、消費量が増加すれば、油面が油面位置P1 より低下して信号を発信し、消費油量が減少すれば、油面が油面位置P2 より上昇して信号を発信するもので、霧化能力の監視機能を付加することになる。
【0023】
また、霧化油量が単位時間当たり一割程増減しても、潤滑には殆ど問題を生じなく、二割になっても同様である。更に、油面位置P1 ,P2 の位置を近づけることによる不具合(停止の原因)を解消するため、▲1▼単位時間を少々長くしたり、▲2▼油面位置P1 ,P2 の位置関係を広いものにする等の対応が必要となる。
【0024】
尚、本発明の噴霧潤滑装置は、本実施例に限定されることなく、本発明の目的の範囲内で自由に設計変更し得るものであり、本発明はそれらの全てを包摂するものである。
【0025】
【発明の効果】
本発明は上述のように構成され、加圧油槽に供給する油量を少量一定にすること及び油面位置P1 ,P2 の位置を近づけ、霧化機能が正常である場合は、少量一定供給直後の油面位置をこの油面位置P1 ,P2 位置の中間とし、消費量が増加すれば、油面が油面位置P1 より低下して信号を発信し、消費油量が減少すれば、油面が油面位置P2 より上昇して信号を発信するため、霧化能力自体の監視機能を持つ噴霧潤滑装置を提供できるものであり、また、噴霧潤滑以外の目的であっても、消費液量を管理するシステムとして流用可能であり、単位時間当たりにどれだけの量を使用する機器であるか、使用量の増減などを監視できるなどの優れた効果を奏するものである。
【0026】
このように本発明の噴霧潤滑装置は、霧化能力の監視機能を持つことができ、また、構成が単純であるため大量生産に適し、価格も低廉なものとして需要者に提供できるなど、本発明を実施することはその実益的価値が甚だ大である。

The oil quantity signal originating hands stage, the quantitative amount of oil than the replenishment oil tank 2 and supplied to the pressurized oil tank 1, when the consumption of the oil is increased by defect occurrence of something, the oil level of the pressurized oil tank 1 reduced outgoing increase signal spray oil amount in the oil surface position P 1, when the consumption of the oil is decreased, lowering the signal spray oil amount of oil level rise in the oil level position P 2 of the pressurized oil tank 1 It is programmed to send as.
[0019]
For example, as shown in FIG. 3, within the specified time t, when the changeover signal by lowering the oil level of the level switch in the oil surface position P 1 is actuated (D point), the abnormal signal of the multi dissipated in the point D It will be the origin of the specified time when it is sent and replenishment is started at point D and re-authorized. Incidentally, what is refueling at a defined time minus limit t within 1 is determined to be normal, abnormal signal of small consumer is originated by the specified time plus limit t 2 time.
[0020]
