（産業上の利用分野）
本発明は製鉄所における圧延ロール軸受、下水処理場の
コンベア用軸受等に主としてグリースを供給する集中潤
滑給油装置に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a centralized lubrication and oil supply system that primarily supplies grease to rolling roll bearings in steel plants, conveyor bearings in sewage treatment plants, and the like.
（従来技術）
集中潤滑給油装置の分配弁は大別して並列作動形の複管
式（ダブルライン方式）と進行作動形の単管式（シング
ルライン方式）が存在し、現在双方と６広く利用されて
いるが、一方の特長とするところは他方の短所となって
おり、互いに問題点を抱えている。(Prior art) Distribution valves for centralized lubrication and oil supply systems can be roughly divided into two types: a parallel-acting double-tube type (double-line system) and a progressive-acting single-tube type (single-line system). However, the strengths of one are the weaknesses of the other, and both have problems.

ら１ｇ！屈ではできても実際にはできないといった短所
がある。For example, the double line system is mainly used for large equipment such as steel plants, and can cover both the number of oil supply ports and the piping distance.If there are currently 10,001 oil supply ports (bearings, etc.), one of them is Even if lubrication becomes impossible due to clogging of bearings or piping, the remaining 9990s have the advantage of being able to be refueled without any problems. On the other hand, since two main pipes to the distribution valve used for this are required, the piping cost increases. In addition, in order to find one place where refueling is not possible, check the 1000 wood indicator rod that moves up and down with the operation of the distribution valve. 1g due to constraints such as machine operating conditions! The disadvantage is that although it can be done in a limited space, it cannot actually be done.

とである。How to use The single-line system has the advantage that whether there are 1,000 or 10 lubrication points, if one lubrication point becomes clogged, it will be impossible to supply lubrication to all lubrication points.
It has the advantage that feedback can be obtained easily and inexpensively. Also, since there is only one pipe to the distribution valve, it has the advantage that the piping cost is lower than that of a double line. However, the advantage of being able to confirm fuel supply through feedback etc. is also a disadvantage. This is because, because of one point where refueling is not possible, refueling to the remaining normal refueling points is interrupted.

By visually observing e, it can be confirmed that the grease is being pushed out from each of the discharge ports 2a to 2d h (lubricating confirmation). The distribution valve 2 shown in the figure is a single discharge type, that is, the grease is discharged from one place (discharge port 2) when the main piston reciprocates.
A to 2d) are shown, but it is also possible to adopt a double discharge type valve arrangement in which the reciprocating grease 11 of the main piston is guided to separate discharges [1].

ている。4 to 7 are single line type distribution valves (progressive type valve distribution), and the supply ports 4a to 7a and the double line distribution valve 2
The discharge ports 2a to 2d are oil supply pipes a- with different diameters and lengths.

いる。Therefore, flow resistance (pressure loss) downstream from distribution valves 4 to 7
are approximately equal, and by supplying a pressure of, for example, 40 Kg/ci to the supply ports 4a to 7a of each distribution valve 4 to 7, an optimum amount of grease can be supplied to each oil supply point 9.

近いものは遠いものより給油管口径が小さくなる。The diameters of the oil supply pipes a to d are determined in advance by Tomoe calculations based on conditions such as the installation location of the distribution valves 4 and 7 (length, flow pattern) so that the flow resistance (pressure loss) is approximately equal. has been done. Therefore, if the back pressure of the greasing pipe 8 and the lubrication point 9 is constant at each distribution valve 4 to 7, the installation positions of the single line distribution valves 4 to 7 will be such that those closer to the double line distribution valve 2 will receive more lubrication than those farther away. The pipe diameter becomes smaller.

１ｅの操作回数が少なくてすむ利点がある。Since the movement of the indicator rod 2e of the double line distribution valve 2 due to pump operation reciprocates at approximately the same speed, clogging in and after the oil supply pipes a-d can be easily identified because the indicator rod 2e does not move. Can be done. Also, install a double line distribution valve 2 in the visible range! However, since they are small in number, the movement of all the indicator rods 2e can be easily observed, and even if one of the fuel supply pipes a to d is damaged, the double line distribution valve indicator rod 2e leading to the damaged location can be easily monitored. Since the movement of one object moves faster than the other objects, abnormalities in the device can be immediately detected. Furthermore, since the single line distribution valves 4 to 7 are connected to the discharge ports 2a to 2d of the double line distribution valve 2, a large number of oil supply points can be covered. Therefore, it is much more economical than using the double line distribution valve 2 alone. Furthermore, since the lengths of the main pipes A and B to the double line distribution valve 2 are relatively short (within 1 TrL), the residual pressure when switching between the main pipes A and B can be ignored, and the residual pressure instantly returns to O. Also, supervisor A
, B can also be ignored, so there is an advantage that the number of operations of the manual handle 1e can be reduced.
次に本発明の装置の利点を詳述する。Next, the advantages of the device of the present invention will be explained in detail.
（１）運転と作動チェックが同時に可能親分配弁２がポ
ンプと共に操作員の目前に位置しており、ポンプを操作
しながら分配弁２の作動チェックができる。(1) Operation and operation check can be performed at the same time The main distribution valve 2 is located in front of the operator along with the pump, and the operation of the distribution valve 2 can be checked while operating the pump.
（２）給脂精度の向上

の確認もできる。(2) Improving greasing accuracy The fact that the parent distribution valve 2 uses a double-pipe type means that even if there is an unevenness in pressure loss after each discharge port 2a to 2d of the distribution valve 2, the main piston will It has a structure that can reliably operate up to the end of the stroke, and can also be confirmed using the indicator rod 2e.
（３）油最調整が１個所集中力式となる。(3) Oil adjustment is concentrated in one place.
従来は並列作動形弁配弁を給脂すべき機械の各所に分散
して取イ４けることが多（、分配弁の作動点検と共に各
分配弁の設置位置まで足を運ぶ必要があるが、本発明の
装置は１個所で全数の抽出調節が行える。Conventionally, parallel-acting valve distribution valves were often distributed to various parts of the machine to be greasing (although it was necessary to visit the installation location of each distribution valve while checking the operation of the distribution valves). The device of the present invention allows for all brewing adjustments to be made in one place.
（４）親分配弁以降の開基状態がキャッチできる。(4) The open state after the parent distribution valve can be detected.
親分配弁以降の配管、子分配弁及び軸受等にブロック現

異状に増大して、ブロックを生じた系統の指示棒が作動
しなかったり、又は若干作動してストローク途中でスト
ップする等によ゛り異状作動がキャッチできる。If a blocking phenomenon (clogging) occurs in piping, child distribution valves, bearings, etc. after the parent distribution valve, the pressure loss after the parent distribution valve will abnormally increase, causing the indicator rod of the system where the blockage occurred to operate. Abnormal operation can be detected if it does not work, or if it starts slightly and stops midway through the stroke.

る。(5) Catching leaks in piping between parent and child distribution valves If a leak occurs due to a break in the oil supply pipe a-d between parent and child distribution valves 2.4 and 7 or other causes, check the operation screw of the parent and child distribution valve indicator rod 2e. 1~
It is possible that there is a leak due to the abnormally fast rate of change! I can do 7 tsuji. In addition, not only due to leaks, but also when a considerable amount of air enters the piping between the parent and child, the pressure loss decreases and the operating speed of the indicator rod in that system increases, allowing you to detect any abnormalities.
上記（４）、（５）は共に親分配弁以降の流動抵抗の変
化が、親分配弁指示棒２ｅの作動スピードの変化となっ
て表れることを利用した異状のキャッチ法である。Both (4) and (5) above are methods for catching abnormalities that utilize the fact that a change in flow resistance after the parent distribution valve appears as a change in the operating speed of the parent distribution valve indicator rod 2e.
（６）高圧系配管の短縮
高圧系配管とはポンプから出た配管に接続される一次分
配弁２までの配管Ａ、Ｂを指すが、これを言い換えると
、配管が破損してリークを生じた場合、ポンプからの流
油量がそのままリーク徂となってポンプ運転中は連続し
てリークを継１ｆｃづる配管のことである。(6) Shortening of high-pressure system piping High-pressure system piping refers to piping A and B connected to the piping from the pump up to the primary distribution valve 2. In other words, the piping is damaged and a leak occurs. In this case, the amount of oil flowing from the pump becomes a leak, and the leak continues to flow for 1 fc while the pump is in operation.
前述のように従来は複管式分配弁を主機回り各所に設置
して、ポンプとの間を２木の主管Δ、１３で接続してお
り、その配管の延べ長さは数拾メートル或はそれ以上の
場合が多い。As mentioned above, in the past, double-pipe distribution valves were installed at various locations around the main engine, and they were connected to the pump with two main pipes Δ, 13, and the total length of the pipes was several tens of meters or more. Often more than that.
しかし本発明の装置はポンプと−次分配弁２（親分配弁

り、リークが発生してもポンプを操作している［、１前
でキ１１ツヂできる。However, in the device of the present invention, the connecting pipes A and B between the pump and the secondary distribution valve 2 (main distribution valve) are much shorter, with a total length of about 2 m, which is several percent shorter than the conventional system. It can be significantly reduced to cents. Therefore, the number of high-pressure pipes and fittings used is extremely reduced, the probability of leak occurrence is close to zero, and even if a leak occurs, the pump can be operated in advance.
（７）管内容積の大幅減少化

４４ｔｌｉが少なくてＪみ、グリースの回転周ＩＩが短
縮されると共に、新鮮度も向上する。(7) Significant reduction in pipe volume When compared with conventional central greasing equipment that uses only double-pipe distribution valves, as can be seen in the previous section, the high-pressure system - secondary piping is significantly shortened. Then, the piping a-d between the parent and child distribution valves
Even if you add up the three stages of piping (medium pressure system secondary piping) and piping from child distribution valves 4 to 7 to greasing point 9 (low pressure greasing piping), the internal volume of the pipes is often significantly smaller. In reality, it is less than a fraction of that. Therefore, the grease inside the pipe is
44tli is reduced, the rotational circumference II of the grease is shortened, and the freshness is also improved.
（８）給脂用分配弁４〜７の設置位置制限の緩和複管式
分配弁のみを使用した従来の装置では、分配弁の取付位

。(8) Relaxation of restrictions on the installation positions of greasing distribution valves 4 to 7 In conventional equipment that uses only double-pipe distribution valves, the installation position of the distribution valves can be checked by checking the finger rod and adjusting all fd. However, in the device of the present invention, the distribution valves 4 to 7 that perform direct greasing are progressively actuated child distribution valves, so the above conditions are not required, and the range of mounting positions can be widened.
（９）据付配管工事のコストダウン
前記（６）項による高圧系配管の１！異的な短縮と、（
７）項の管内容積の大幅節減は、配管材の節減と同時に

ン要望にも役立つものである。(9) Cost reduction of installation piping work1! Unusual shortening and (
The significant reduction in pipe internal volume described in item 7) means a reduction in piping materials as well as a reduction in piping processing man-hours. Therefore, reducing the cost of piping materials and piping processing, which accounts for about 70% of the price structure of a central lubrication system including installation costs, will also help meet customer demands for cost reduction.
（１０）据付配管工期の短縮
前項で配管材の節減と配管工数の低減を述べたが、これ
はそのまま工事の短縮に寄与するも゛のである。(10) Reducing the installation period of piping work The previous section mentioned the reduction in piping materials and piping man-hours, and this directly contributes to shortening the construction period.

ば工事が粗雑どなり、グリースの渾洩とか回路内にゴミ
の侵入が生じやすく、後日にクレームを生ずる原因とな
ることが実際面上多いと予想される。Generally, when mechanical equipment is newly installed or repaired, the installation and assembly of the machinery is carried out in advance, and the installation and piping for centralized greasing often has to be carried out at the end of the construction process. Therefore, if the installation or assembly of the main engine is delayed in construction work that is subject to construction period restrictions, there is a strong tendency for the construction period for centralized lubrication to be compressed, which may lead to shoddy construction work, grease leakage, and dirt intrusion into the circuit. In practice, it is expected that this will likely occur and will often lead to claims later.
特に従来の複管式の配管方式は高圧の２水配管Δ、Ｂの
距離が長く、分配弁との接続配管等配管技術及び配管工
数を要する部分が多いのが通常であり、これが工期制限
や工事予算に制約されて、粗雑な配管の原因となりがら
である。In particular, in conventional double-pipe piping systems, the distance between the two high-pressure water pipes Δ and B is long, and there are many parts that require piping technology and man-hours, such as connecting piping with distribution valves, which limits the construction period and However, due to construction budget constraints, this can lead to shoddy piping.
しかし本発明の装置は前述の配管材の節減による工数減
はもちろんのこと、上記配管技術を要する高圧系配管が
ぜ口に近いことは、工期短縮の最大原因となり得る。However, the apparatus of the present invention not only reduces the number of man-hours due to the above-mentioned savings in piping materials, but also the fact that the high-pressure system piping that requires the above-mentioned piping technology is close to the opening can be the biggest cause of shortening the construction period.
