Description

この発明は、マンコンベアのチェーン部に潤滑油を供給する給油装置に関するものである。   The present invention relates to an oil supply device that supplies lubricating oil to a chain portion of a man conveyor.

従来のマンコンベアの給油装置には、ポンプを有する1つの給油本体ユニットに、潤滑油の定量供給を行う絞り弁を備えた少なくとも1つの油圧回路と、ポンプの一動作中に一定量の潤滑油を一回のみ供給する定量供給弁を備えた少なくとも1つの油圧回路とをそれぞれ接続したことによって、単一の給油装置により、給油タイミング及び給油量の異なる複数の給油箇所へ、常に適量の給油を可能にしたものがある。(例えば、特許文献1参照)   A conventional oil supply device for a man conveyor includes at least one hydraulic circuit provided with a throttle valve for supplying a fixed amount of lubricating oil to one oil supply main unit having a pump, and a certain amount of lubricating oil during one operation of the pump. By connecting at least one hydraulic circuit with a fixed supply valve that supplies oil only once, a single oiling device always supplies an appropriate amount of oil to multiple oiling locations with different oiling timings and oiling amounts. There is something that made it possible. (For example, see Patent Document 1)

特開平6−50494号公報JP-A-6-50494

特許文献1に記載のマンコンベアの給油装置では、単一の給油装置によって、給油タイミング及び給油量の異なる複数の給油箇所への適量な給油を可能としている。しかし、給油配管先端に設けられている吐出ノズルに目詰まりが生じた場合には、そのことを知る手段がないため、給油駆動装置(給油ポンプ)が稼動しているにもかかわらず、潤滑油の塗布を必要とする潤滑部に十分な潤滑油が供給されていない、又は潤滑油が全く供給されていないという問題が生じていた。また、吐出ノズルに目詰まりが生じているかを実際に確認するためには、給油ポンプを稼動させた後に、作業者が吐出ノズルからの潤滑油の供給状態を確認する必要があった。   In the oil supply device for the man conveyor described in Patent Document 1, an appropriate amount of oil can be supplied to a plurality of oil supply locations having different oil supply timings and oil supply amounts by a single oil supply device. However, if the discharge nozzle provided at the tip of the oil supply pipe is clogged, there is no means for knowing this, so the lubricating oil is used even though the oil supply drive (oil supply pump) is operating. There has been a problem that sufficient lubrication oil is not supplied to the lubrication part that needs to be applied, or no lubrication oil is supplied at all. Further, in order to actually check whether the discharge nozzle is clogged, it is necessary for the operator to check the supply state of the lubricating oil from the discharge nozzle after operating the oil supply pump.

また、使用する潤滑油の粘度が高いほど、上記のような吐出ノズルの目詰まりは深刻な問題となる。従来のような低粘度の潤滑油を使用する場合には、潤滑部であるチェーンから潤滑油が落ち易いため、頻繁に、例えばマンコンベアの運転時間が数十時間経過する毎に給油する必要があった。これに対し、給油頻度を少なくするために高粘度の潤滑油を使用することによって、例えば運転時間が数百時間経過したら給油する長期給油インターバルを実現することも考えられている。このような高粘度の潤滑油を使用する場合には、1回の給油が行われないことによって非常に長い無給油期間が発生してしまうため、潤滑油の不足によりチェーンの伸びや騒音などが発生することが考えられている。また、高粘度の潤滑油の使用によって給油インターバルが長くなるため、ゴミなどが付着して吐出ノズルの先端が固まり易くなるという問題もある。   Further, the higher the viscosity of the lubricating oil used, the more serious the clogging of the discharge nozzle as described above. When using a low-viscosity lubricating oil as in the past, the lubricating oil tends to fall from the chain that is the lubricating part, so it is necessary to refuel frequently, for example, every time the man conveyor runs for several tens of hours there were. On the other hand, it is also considered to realize a long-term lubrication interval in which lubrication is performed after several hundred hours of operation, for example, by using high-viscosity lubricating oil in order to reduce the frequency of lubrication. When using such high-viscosity lubricating oil, a very long non-lubricating period will occur due to the lack of a single refueling. It is thought to occur. In addition, since the oil supply interval becomes longer due to the use of high-viscosity lubricating oil, there is also a problem that dust or the like adheres and the tip of the discharge nozzle tends to harden.

ゴミの付着や潤滑油の凝固などによって吐出ノズルに上記のような目詰まりが生じる場合には、通常、潤滑油の供給が突然停止するわけではなく、潤滑油の供給が完全に停止する前に、その供給量が徐々に減少していく過程を経る。つまり、吐出ノズルから糸状に連続的に潤滑油が供給されていたものが、吐出ノズルの一部にゴミの付着や潤滑油の凝固などが発生して、徐々にその供給量が減少していく。この状態を放置してさらに時間が経過すると、間欠的に潤滑油が供給される滴下状態を経て、最終的には全く潤滑油を供給することができない状態となってしまう。したがって、給油ポンプの稼働時間を常に一定に保っている場合には、潤滑油の供給量が減少し始めてからはチェーンに必要な量の潤滑油が供給されなくなるという問題が生じていた。特に、潤滑油が間欠的に供給される場合には、チェーンの一部に潤滑油が全く供給されていないという状態が生じていた。   When the above-mentioned clogging occurs on the discharge nozzle due to dust adhesion or solidification of the lubricating oil, the supply of the lubricating oil does not usually stop suddenly, but before the supply of the lubricating oil stops completely The process of gradually decreasing the supply amount. In other words, what is continuously supplied in the form of a thread from the discharge nozzle, dust adheres to the part of the discharge nozzle, solidification of the lubricant, etc., the supply amount gradually decreases . If a further time elapses after leaving this state, the lubricating oil is intermittently supplied, and finally the lubricating oil cannot be supplied at all. Therefore, when the operating time of the oil supply pump is kept constant, there has been a problem that a necessary amount of lubricating oil cannot be supplied to the chain after the supply amount of the lubricating oil starts to decrease. In particular, when the lubricating oil is intermittently supplied, there has been a state in which no lubricating oil is supplied to a part of the chain.

この発明は、上述のような課題を解決するためになされたもので、給油配管先端に設けられた吐出ノズルの目詰まりや吐出ノズルからの潤滑油の供給を検出することができるマンコンベアの給油装置を提供することである。   The present invention has been made to solve the above-described problems, and is an oil supply for a man conveyor that can detect clogging of a discharge nozzle provided at the tip of an oil supply pipe and supply of lubricating oil from the discharge nozzle.

It is a longitudinal cross-sectional view in the oil supply state of an oil supply apparatus.

図において、潤滑油を収容する潤滑油タンク(図示せず)に連結された給油配管(図示せず)は、この潤滑油タンクから潤滑油の塗布を必要とする潤滑部の上方まで延設され、その潤滑部側端部に吐出ノズル2が設けられている。この吐出ノズル2の下方には、一方向に傾斜している傾斜面3cを底面に有する案内手段からなる受け皿3が備えられ、この傾斜面3cの上部が吐出ノズル2の下方に位置するように設置されている。傾斜面3cの下部には、その中央部に分岐部からなる平面視三角形の凸部3aが設けられ、この凸部3aと凸部3aの両側に設けられた側壁3dとで2つの給油口3bが形成されている。また、受け皿3の下方には潤滑部からなるチェーン1が備えられており、チェーン1のピンリンクプレート1bとローラリンクプレート1cとの間に形成された間隙1aの上方に前述した給油口3bが位置するように、受け皿3が配置されている。また、この受け皿3には、傾斜面3cの上方に側壁3dに渡って軸4が締結固定されており、この軸4に油受け5が設けられている。この油受け5は、吐出ノズル2の下方に受け部5aを有し、軸4を中心にして所定角度内を回動することができる構成となっている。さらに、この受け皿3には、油受け5の変位を検出するセンサ6(例えば、近接センサ)が固定台7を介して設置され、油受け5とセンサ6とで検出手段が構成されている。   In the drawing, an oil supply pipe (not shown) connected to a lubricating oil tank (not shown) that contains lubricating oil extends from the lubricating oil tank to above a lubricating part that requires application of lubricating oil. The discharge nozzle 2 is provided at the end of the lubrication part. Below the discharge nozzle 2, there is provided a tray 3 comprising guide means having an inclined surface 3c inclined in one direction on the bottom surface, and the upper portion of the inclined surface 3c is positioned below the discharge nozzle 2. is set up. At the lower part of the inclined surface 3c, a convex portion 3a having a triangular shape in a plan view is provided at the center thereof, and two oil filler ports 3b are formed by the convex portion 3a and side walls 3d provided on both sides of the convex portion 3a. Is formed. Further, a chain 1 made of a lubricating portion is provided below the tray 3, and the aforementioned oil filler port 3 b is located above the gap 1 a formed between the pin link plate 1 b and the roller link plate 1 c of the chain 1. The tray 3 is arranged so as to be positioned. Further, a shaft 4 is fastened and fixed to the tray 3 over the side wall 3d above the inclined surface 3c, and an oil receiver 5 is provided on the shaft 4. The oil receiver 5 has a receiving portion 5 a below the discharge nozzle 2 and is configured to be able to rotate within a predetermined angle about the shaft 4. Further, a sensor 6 (for example, a proximity sensor) for detecting the displacement of the oil receiver 5 is installed in the tray 3 via a fixed base 7, and the oil receiver 5 and the sensor 6 constitute a detection means.

次に、潤滑油を潤滑部に供給する動作ついて説明する。
潤滑油が吐出ノズル2から供給されない無給油状態では、油受け5は受け部5a側の方が軽いため、受け部5a側が上方となるように斜めに静止している(図2)。ここで、マンコンベアの運転時間が前回の給油から所定時間経過すると、給油ポンプが自動的に運転を開始し、潤滑油タンクに収容されている潤滑油が、給油配管を介して吐出ノズル2から供給される。吐出ノズル2から供給された潤滑油は、吐出ノズル2の真下に設置されている油受け5の受け部5aに落下する。すると、受け部5aに落下した潤滑油によって油受け5は受け部5a側が重くなるため、軸4を中心にして回転し、受け部5a側が下方となるように斜めに静止する(図3)。受け部5aから受け皿3の傾斜面3aに流れ出た潤滑油は、傾斜面3cに沿って下方に進み、傾斜面3cのほぼ中央部に位置する凸部3aの頂点で2方向にほぼ均等に分かれてそれぞれの給油口3bに達する。さらに、それぞれの給油口3bから落下した潤滑油は、チェーン1の間隙1aへと供給され、潤滑油の塗布が必要なチェーン1のピンとブッシュ(図示せず)との間に潤滑油が浸透することになる。また、給油ポンプは運転が開始されてから所定時間経過すると自動的に運転が停止されるように制御されている。このため、給油ポンプが停止し、油受け5の受け部5aに潤滑油が供給されなくなると、油受け5は再び受け部5a側が軽くなり、軸4を中心にして回転し、受け部5a側が上方となるように斜めに静止する(図2)。なお、この油受け5の一連の動きは、受け皿3に固定されているセンサ6で検出され、その検出結果は警告ランプや警告表示などの報知手段(図示せず)によって監視員などが確認できるようになっている。
Next, the operation for supplying the lubricating oil to the lubricating part will be described.
In an oil-free state in which no lubricating oil is supplied from the discharge nozzle 2, the oil receiver 5 is lighter on the receiving portion 5 a side, so that it stays diagonally so that the receiving portion 5 a side is upward (FIG. 2). Here, when the operation time of the man conveyor is a predetermined time after the previous refueling, the refueling pump automatically starts operation, and the lubricating oil stored in the lubricating oil tank is discharged from the discharge nozzle 2 via the refueling pipe. Supplied. The lubricating oil supplied from the discharge nozzle 2 falls to the receiving portion 5a of the oil receiver 5 installed immediately below the discharge nozzle 2. Then, since the oil receiver 5 becomes heavy on the side of the receiving part 5a due to the lubricating oil falling on the receiving part 5a, the oil receiver 5 rotates around the shaft 4 and stops diagonally so that the receiving part 5a side is downward (FIG. 3). The lubricating oil that has flowed out from the receiving portion 5a to the inclined surface 3a of the tray 3 proceeds downward along the inclined surface 3c, and is divided approximately evenly in two directions at the apex of the convex portion 3a located substantially at the center of the inclined surface 3c. Reach the respective fuel filler openings 3b. Further, the lubricating oil dropped from each oil supply port 3b is supplied to the gap 1a of the chain 1, and the lubricating oil penetrates between the pin and the bush (not shown) of the chain 1 that needs to be coated with the lubricating oil. It will be. Further, the fuel pump is controlled so that the operation is automatically stopped when a predetermined time elapses after the operation is started. For this reason, when the oil pump is stopped and the lubricating oil is no longer supplied to the receiving portion 5a of the oil receiver 5, the oil receiver 5 is lightened again on the receiving portion 5a side and rotates around the shaft 4, and the receiving portion 5a side is It stops at an angle so as to be upward (FIG. 2). The series of movements of the oil receiver 5 is detected by a sensor 6 fixed to the tray 3, and the detection result can be confirmed by a monitoring person or the like by a notification means (not shown) such as a warning lamp or warning display. It is like that.

この発明の実施の形態1によれば、吐出ノズル2から潤滑油を受ける油受け5が無給油状態と給油状態とにおいて異なる位置で静止するため、この油受け5の位置をセンサ6で検出することによって、吐出ノズル2から正常に潤滑油が供給されているか否かを判断することができる。すなわち、吐出ノズル2に目詰まりが生じた場合には、給油ポンプの運転が開始されても吐出ノズル2から潤滑油が供給されないために、油受け5の回転が生じない。したがって、この時の油受け5の位置をセンサ6で検出することにより、吐出ノズル2から潤滑油が供給されていないことを判断することができる。なお、油受け5と軸4との間にゴミなどが付着することによって、油受け5の動作が悪くなった場合にも、センサ6で検出された給油状態と無給油状態での油受け5の位置を比較することにより、油受け5が正常に動作しているのかを判断することができる。また、油受け5からチェーン1の上方まで潤滑油を導く傾斜面3cは、給油装置の上方又は斜め上方から目視することができるため、給油ポンプを稼動させることなく容易に傾斜面3cの状態を確認することができる。したがって、給油口3bなどに小さなゴミが付着している場合でも発見し易く、メンテナンス作業を容易に行うことができる。なお、潤滑油が通る穴を有する、取外し可能な透明な蓋を受け皿3の上部に設けることで、実施の形態1と同様の効果を得ることができるとともに、装置上方からのゴミなどの進入を防ぐこともできる。   According to the first embodiment of the present invention, the oil receiver 5 that receives the lubricating oil from the discharge nozzle 2 stops at different positions in the non-oil supply state and the oil supply state, so the position of the oil receiver 5 is detected by the sensor 6. Thus, it can be determined whether or not the lubricating oil is normally supplied from the discharge nozzle 2. That is, when the discharge nozzle 2 is clogged, the oil receiver 5 does not rotate because the lubricant oil is not supplied from the discharge nozzle 2 even when the operation of the oil supply pump is started. Therefore, by detecting the position of the oil receiver 5 at this time by the sensor 6, it can be determined that the lubricating oil is not supplied from the discharge nozzle 2. Even when dust or the like adheres between the oil receiver 5 and the shaft 4 and the operation of the oil receiver 5 is deteriorated, the oil receiver 5 in the oil supply state detected by the sensor 6 and in the non-oil supply state. It is possible to determine whether the oil receiver 5 is operating normally by comparing the positions of. Moreover, since the inclined surface 3c which guides lubricating oil from the oil receiver 5 to the upper part of the chain 1 can be visually observed from the upper side or the diagonally upper side of the oil supply device, the state of the inclined surface 3c can be easily changed without operating the oil supply pump. Can be confirmed. Therefore, even when small dust is attached to the fuel filler opening 3b or the like, it is easy to find and maintenance work can be easily performed. It should be noted that by providing a removable lid having a hole through which lubricating oil passes on the upper part of the receiving tray 3, the same effect as in the first embodiment can be obtained, and intrusion of dust and the like from above the apparatus can be achieved. It can also be prevented.

また、吐出ノズル2にゴミなどが付着することによって吐出ノズル2からの潤滑油の供給量が減少した場合には、正常な給油時の油受け5の位置と給油ポンプ稼動時に検出された油受け5の位置とを比較することにより、吐出ノズル2からの潤滑油の供給量を判断することができる。特に、吐出ノズル2からの潤滑油の供給が間欠的な滴下状態になった場合には、油受け5の位置がポンプ稼動時に一定しないため、容易に検出することができる。また、吐出ノズル2からの潤滑油の供給量に異常が検出された際に作業員が直ちに修理を行うことができない場合には、検出された潤滑油の供給量から判断して、所定時間の給油ポンプ稼動後に再度給油ポンプを必要時間稼動させることによって、チェーン1に必要な量の潤滑油を供給することが可能となり、チェーン1の磨耗や騒音などを防止することが可能となる。このような潤滑油の供給量の検出は、吐出ノズル2の目詰まりが生じ易く、給油インターバルが長い高粘度の潤滑油を使用する場合には特に有効である。   Further, when the supply amount of lubricating oil from the discharge nozzle 2 decreases due to dust or the like adhering to the discharge nozzle 2, the position of the oil receiver 5 during normal oil supply and the oil receiver detected during operation of the oil pump By comparing with the position 5, the supply amount of the lubricating oil from the discharge nozzle 2 can be determined. In particular, when the supply of lubricating oil from the discharge nozzle 2 is intermittently dropped, the position of the oil receiver 5 is not constant when the pump is operating, and therefore can be easily detected. In addition, if an operator cannot immediately repair when an abnormality is detected in the supply amount of the lubricating oil from the discharge nozzle 2, it is determined from the detected supply amount of the lubricating oil, By operating the oil pump again for a necessary time after the oil pump is operated, it becomes possible to supply a necessary amount of lubricating oil to the chain 1 and to prevent wear and noise of the chain 1. Such detection of the supply amount of the lubricating oil is particularly effective when the high-viscosity lubricating oil having a long oil supply interval is used because the discharge nozzle 2 is easily clogged.

なお、実施の形態1では、吐出ノズル2から供給される潤滑油の検出手段として油受け5とセンサ6とを使用しているが、油受け5の代わりに羽根車を使用して、吐出ノズル2から潤滑油が供給された場合にこの羽根車が回転するような構成とし、センサ6の代わりに羽根車の回転速度(回転数)を検出するセンサを使用して、潤滑油の供給を検出する構成としても実施の形態1と同様の効果を得ることができる。   In the first embodiment, the oil receiver 5 and the sensor 6 are used as means for detecting the lubricating oil supplied from the discharge nozzle 2. However, instead of the oil receiver 5, an impeller is used and the discharge nozzle The configuration is such that the impeller rotates when lubrication oil is supplied from No. 2, and the supply of the lubrication oil is detected using a sensor that detects the rotational speed (number of rotations) of the impeller instead of the sensor 6. Even if it is the structure to perform, the effect similar to Embodiment 1 can be acquired.

また、実施の形態1では、チェーン1に潤滑油を供給するために2つの給油口3bを有する案内手段を使用したが、潤滑部の種類に対応して案内手段の形状や給油口の数を変更することで、チェーンのみならず、さまざまな潤滑部に応用することが可能である。   In the first embodiment, the guide means having the two oil supply ports 3b is used to supply the lubricating oil to the chain 1. However, the shape of the guide means and the number of oil supply ports are changed according to the type of the lubrication part. By changing, it can be applied not only to the chain but also to various lubrication parts.
