Description

この発明は、チェーン部に給油頻度を少なくできる高粘度の潤滑油を給油できるようにしたマンコンベアの自動給油装置に関するものである。   The present invention relates to an automatic oil supply device for a man conveyor that can supply a highly viscous lubricating oil capable of reducing the frequency of oil supply to a chain portion.

マンコンベアの駆動部であるチェーン部に潤滑油を給油する自動給油装置においては、潤滑油として、従来は低粘度の潤滑油（例えば鉱物油等）が使用されていた。この低粘度の潤滑油を使用した場合は、潤滑部であるチェーンから潤滑油が落ち易く頻繁に給油が必要となる。その為、マンコンベアの運転時間が数十時間を経過したら、自動的に潤滑油を給油するようにしていた。この対策として、給油頻度を少なくできる高粘度の潤滑油（例えば合成油等）を用いることにより、例えば運転時間が数百時間経過したら自動的に給油する長期給油インターバルを実現することが考えられている。なお、潤滑油の動粘度と温度との関係は図３の特性図に示すとおりである。また、一般機械に備えられる駆動チェーンにおいても、滑らかな動きを維持するために油を塗布しており、油の塗布には自動給油装置が用いられている。この従来技術の自動給油装置として、油の温度変化にかかわらず被給油体（駆動チェーン）に対する吐出量を一定に維持するものがある（例えば、特許文献１参照）。   In an automatic oil supply apparatus that supplies lubricating oil to a chain portion that is a driving portion of a man conveyor, conventionally, a low-viscosity lubricating oil (for example, mineral oil) has been used as the lubricating oil. When this low-viscosity lubricating oil is used, the lubricating oil tends to drop from the chain, which is the lubricating portion, and frequent oil supply is required. Therefore, the lubricating oil is automatically supplied when the operation time of the man conveyor has exceeded several tens of hours. As a countermeasure, it is conceivable to use a highly viscous lubricating oil (for example, synthetic oil) that can reduce the frequency of refueling to realize a long-term refueling interval that automatically refuels after several hundred hours of operation, for example. Yes. The relationship between the kinematic viscosity and the temperature of the lubricating oil is as shown in the characteristic diagram of FIG. Also, in a drive chain provided in a general machine, oil is applied in order to maintain a smooth movement, and an automatic oiling device is used for applying the oil. As this prior art automatic oil supply device, there is one that maintains a constant discharge amount to an oil supply body (drive chain) regardless of a change in oil temperature (see, for example, Patent Document 1).

従来の低粘度の潤滑油を使用した場合は、潤滑部であるチェーンから潤滑油が落ち易く頻繁に給油が必要となるという問題があった。また、高粘度の潤滑油を使用した場合は、給油インターバルが従来の数十時間から数百時間へと大幅に長くなり、給油配管や給油ノズル内に空気が侵入し（エア噛み）、給油ポンプを起動しても適正量の給油が行われないことがある。また、高粘度の潤滑油を使用すると、低温で流動不良が生じ、給油不足になることがある。また、特許文献１に記載のものは、圧力温度補償機能付きの流量制御弁で温度変化に対応して一定給油するものであり、高粘度の潤滑油を使用できるように特別に考慮が払われたものではない。   When conventional low-viscosity lubricating oil is used, there is a problem that the lubricating oil tends to fall from the chain that is the lubricating portion, and frequent oil supply is required. In addition, when high-viscosity lubricating oil is used, the oiling interval is greatly increased from several tens of hours to several hundred hours, and air enters the oiling pipes and oiling nozzles (air engagement). Even if is started, the proper amount of refueling may not be performed. In addition, when a high-viscosity lubricating oil is used, poor flow may occur at low temperatures, resulting in insufficient lubrication. Further, the one described in Patent Document 1 is a flow control valve with a pressure temperature compensation function that supplies a constant amount of oil corresponding to a temperature change, and special consideration is given so that a high-viscosity lubricating oil can be used. Not a thing.

図１はこの発明の実施の形態１におけるマンコンベアの自動給油装置を示すシステム構成図、図２はこの発明の実施の形態１におけるマンコンベアの自動給油装置の動作を説明するフローチャートである。
図において、マンコンベアは、複数の踏段１を連結した踏段チェーン２、この踏段チェーンを駆動するチェーンスプロケット３、このチェーンスプロケットを駆動するドライブチェーン４、このドライブチェーンを駆動する駆動モータ５及び減速機６等を備えている。そして、マンコンベアの運転時間が数百時間を経過したら、駆動部である踏段チェーン２及びドライブチェーン４等に自動給油装置により高粘度の潤滑油が自動的に給油される構成となっている。すなわち、自動給油装置は、高粘度の潤滑油（例えば合成油等）が収容された潤滑油タンク７と、このタンク内の潤滑油を適正な温度に予め加熱しておくための加熱ヒータ８と、潤滑油タンク７と各チェーン部付近とを連結する給油配管９、９ａ、９ｂと、この給油配管９ａ、９ｂの途中に設けられ、潤滑油タンク８内の潤滑油を給油配管９ａ、９ｂを通して給油する給油ポンプ１０ａ、１０ｂと、給油配管９ａ、９ｂの先端にそれぞれ設けられ、踏段チェーン２やドライブチェーン４等に高粘度の潤滑油を供給する給油ノズル１１ａ、１１ｂと、各給油ポンプ１０ａ、１０ｂと各給油ノズル１１ａ、１１ｂとの間の給油配管９ａ、９ｂにそれぞれ設けられた逆止弁１２ａ、１２ｂと、各給油ノズル１１ａ、１１ｂの手前の給油配管９ａ、９ｂにそれぞれ設けられた絞り装置１３ａ、１３ｂと、各逆止弁１２ａ、１２ｂと各絞り装置１３ａ、１３ｂとの間の各給油配管９ａ、９ｂからそれぞれ分岐された空気取り入れ用の分岐配管１４ａ、１４ｂと、この各分岐配管にそれぞれ設けられた逆止弁１５ａ、１５ｂと、先端に空気取り入れ口１６有しその途中にエアポンプ１７及びエアフィルタ１８を有する空気取り入れ配管１９と、コントローラ２０と、給油ポンプ１０ａ、１０ｂの運転開始と運転停止を制御する給油タイマー２１と、潤滑油タンク７内の潤滑油の温度を検出するサーモセンサ２２とから構成されている。コントローラ２０は、自動給油装置の終了直前或いは給油ポンプ１０ａ、１０ｂの停止直後に給油配管９ａ、９ｂ及び給油ノズル１１ａ、１１ｂ内の潤滑油を押し出すために、エアポンプ１７を起動して空気取り入れ配管１９から給油配管９ａ、９ｂ内に空気を圧送し、給油配管９ａ、９ｂ及び給油ノズル１１ａ、１１ｂ内に残留している潤滑油を給油ノズル１１ａ、１１ｂから外に排出する。また、コントローラ２０は、マンコンベアの運転時間が例えば５００時間を経過したら、潤滑油タンク７内の潤滑油を加熱ヒータ８及びサーモセンサ２２により予め適正な温度となるように暖めておく。給油タイマー２１は、潤滑油が適正な温度になれば、給油ポンプ１０ａ、１０ｂによる給油を開始し、最も長い踏段チェーン２が少なくとも一巡するまでの予定時間、例えば約７０秒を経過してから給油ポンプ１０ａ、１０ｂを停止するようになって給油ノズル１１ａ、１１ｂ内に空気が侵入し易くなるが、上記コントローラ２０により、自動給油装置の終了直前或いは給油ポンプ１０ａ、１０ｂの停止直後に、エアポンプ１７を起動して空気取り入れ配管１９から給油配管９ａ、９ｂ内に空気を圧送し、給油配管９ａ、９ｂ及び給油ノズル１１ａ、１１ｂ内に残留している潤滑油を給油ノズル１１ａ、１１ｂから外に排出するようにしている。これにより、給油配管内に潤滑油が残らないためエア噛みも発生せず、給油ポンプによる適正量の給油を行うことができる。 Embodiment 1 FIG.
1 is a system configuration diagram showing an automatic refueling device for a man conveyor according to Embodiment 1 of the present invention, and FIG. 2 is a flowchart for explaining the operation of the automatic refueling device for a man conveyor according to Embodiment 1 of the present invention.
In the figure, a man conveyor includes a step chain 2 connecting a plurality of steps 1, a chain sprocket 3 for driving the step chain, a drive chain 4 for driving the chain sprocket, a drive motor 5 for driving the drive chain, and a speed reducer. 6 etc. And if the operation time of a man conveyor passes several hundred hours, it will become the structure by which the highly viscous lubricating oil is automatically supplied to the step chain 2 which is a drive part, the drive chain 4, etc. with an automatic oil supply apparatus. That is, the automatic oil supply apparatus includes a lubricating oil tank 7 in which a high-viscosity lubricating oil (for example, synthetic oil) is accommodated, and a heater 8 for preheating the lubricating oil in the tank to an appropriate temperature. The oil supply pipes 9, 9a, 9b for connecting the lubricating oil tank 7 and the vicinity of each chain portion are provided in the middle of the oil supply pipes 9a, 9b, and the lubricating oil in the lubricating oil tank 8 is passed through the oil supply pipes 9a, 9b. Oil supply pumps 10a and 10b for supplying oil, oil supply nozzles 11a and 11b provided at the tips of the oil supply pipes 9a and 9b, respectively, for supplying high-viscosity lubricating oil to the step chain 2, the drive chain 4, etc., and each oil supply pump 10a, Check valve 12a, 12b provided in oil supply piping 9a, 9b between 10b and each oil supply nozzle 11a, 11b, and oil supply piping 9a, 9 before each oil supply nozzle 11a, 11b, respectively And the branch pipes 14a and 14b for taking in air branched from the oil supply pipes 9a and 9b between the check valves 12a and 12b and the throttle apparatuses 13a and 13b, respectively. Check valves 15a and 15b provided on the respective branch pipes, an air intake pipe 19 having an air intake port 16 at the tip thereof, an air pump 17 and an air filter 18 in the middle, a controller 20, and an oil supply pump An oil supply timer 21 that controls the start and stop of operations of 10a and 10b and a thermosensor 22 that detects the temperature of the lubricating oil in the lubricating oil tank 7 are configured. The controller 20 activates the air pump 17 to push out the lubricating oil in the oil supply pipes 9a and 9b and the oil supply nozzles 11a and 11b immediately before the end of the automatic oil supply apparatus or immediately after the oil supply pumps 10a and 10b are stopped. Then, air is pumped into the oil supply pipes 9a and 9b, and the lubricating oil remaining in the oil supply pipes 9a and 9b and the oil supply nozzles 11a and 11b is discharged from the oil supply nozzles 11a and 11b. Further, the controller 20 warms the lubricating oil in the lubricating oil tank 7 in advance so as to reach an appropriate temperature by the heater 8 and the thermo sensor 22 when the operation time of the man conveyor elapses, for example, 500 hours. The lubrication timer 21 starts the lubrication by the lubrication pumps 10a and 10b when the lubricating oil reaches an appropriate temperature, and lubricates after the estimated time until the longest step chain 2 completes at least one round, for example, about 70 seconds. The pumps 10a and 10b are stopped so that air easily enters the oil supply nozzles 11a and 11b. However, the controller 20 allows the air pump 17 immediately before the end of the automatic oil supply device or immediately after the oil supply pumps 10a and 10b are stopped. And air is pumped from the air intake pipe 19 into the oil supply pipes 9a and 9b, and the lubricating oil remaining in the oil supply pipes 9a and 9b and the oil supply nozzles 11a and 11b is discharged from the oil supply nozzles 11a and 11b. Like to do. As a result, no lubricating oil remains in the oil supply pipe, so that no air is caught, and an appropriate amount of oil can be supplied by the oil supply pump.

次に、マンコンベアの自動給油装置の動作について説明する。
先ず、マンコンベアの運転がスタートすると、ステップＳ１で前回の給油から運転時間が一定時間である数百時間が経過したかどうかを積算時間として判断する。ここで前回の給油からの積算運転時間が数百時間を経過していたら、ステップＳ２で加熱ヒータ８により潤滑油を暖め、サーモセンサ２２により潤滑油が適正な温度になったかどうかを検出しコントローラ２０により判断する。高粘度の潤滑油は適正な温度に暖められると、従来の低粘度の潤滑油並みの粘度となる。そうしたら、ステップＳ３で給油ポンプ１０ａ、１０ｂの運転を開始して給油を開始する。次に、ステップＳ４で給油を開始してから最も長い踏段チェーン２が少なくとも一巡するまでの予定時間、例えば約７０秒間給油を継続したかどうかを判断する。ここで７０秒間給油を継続したら、最も長い踏段チェーン２の全てに高粘度の潤滑油が行き渡ったと判断して、ステップＳ５で給油ポンプ１０ａ、１０ｂの運転を停止し給油を停止する。給油終了直前又は給油ポンプの停止直後、ステップＳ６でエアポンプ１７を起動して空気取り入れ配管１９から給油配管９ａ、９ｂ内に空気を圧送し、給油配管９ａ、９ｂ及び給油ノズル１１ａ、１１ｂ内に残留している潤滑油を給油ノズル１１ａ、１１ｂから外に排出する。その後、ステップＳ７でエアポンプ１７を停止する。 Next, operation | movement of the automatic oil supply apparatus of a man conveyor is demonstrated.
First, when the operation of the man conveyor is started, in step S1, it is determined as an accumulated time whether or not several hundred hours, which is a constant operation time, has elapsed since the previous refueling. Here, if several hundred hours have elapsed since the previous refueling, the heating oil is warmed by the heater 8 in step S2, and the thermosensor 22 detects whether or not the lubricating oil has reached an appropriate temperature. Judge 20 When the high-viscosity lubricating oil is warmed to an appropriate temperature, the viscosity becomes the same as that of a conventional low-viscosity lubricating oil. If it does so, in step S3, operation of oil supply pump 10a, 10b will be started, and oil supply will be started. Next, it is determined whether or not refueling is continued for a predetermined time, for example, about 70 seconds, from the start of refueling until the longest step chain 2 completes one cycle. If refueling is continued for 70 seconds, it is determined that high-viscosity lubricating oil has spread over all of the longest step chain 2, and the operation of the oil pumps 10a and 10b is stopped in step S5 to stop refueling. Immediately before the end of refueling or immediately after the stop of the refueling pump, the air pump 17 is activated in step S6 to pump air from the air intake pipe 19 into the refueling pipes 9a and 9b, and remain in the refueling pipes 9a and 9b and the refueling nozzles 11a and 11b. The lubricating oil is discharged from the oil supply nozzles 11a and 11b. Thereafter, the air pump 17 is stopped in step S7.

上記の実施の形態１の説明では、チェーンスプロケット３に巻き掛けられた踏段チェーン２及びチェーンスプロケット３を駆動するドライブチェーン４に高粘度の潤滑油を給油した場合を例に説明しているが、実際には自動給油装置は、移動手摺駆動チェーンにも高粘度の潤滑油を自動給油するものであることは勿論である。   In the above description of the first embodiment, the case where the high-viscosity lubricating oil is supplied to the step chain 2 wound around the chain sprocket 3 and the drive chain 4 that drives the chain sprocket 3 is described as an example. Actually, the automatic oil supply device automatically supplies high-viscosity lubricating oil also to the moving handrail drive chain.
