【発明の詳細な説明】 ＜産業上の利用分野＞ 本発明はエンジン駆動（もしくは、電動式駆動）のポ
ンプにおける圧力制御で、特に高粘度の吹付材の塗料圧
送ポンプの制御装置に関するものである。The present invention relates to a control device for pressure control in an engine-driven (or electric-driven) pump, and more particularly to a controller for a paint pressure pump for high-viscosity spray material. .
＜従来の技術＞ 一般に、塗料用の圧送ポンプは、各種駆動方法によっ
て運転されるが、一般的には空気駆動式、電動式、エン
ジン駆動式が代表的なものとなっている。<Prior Art> Generally, a pressure pump for paint is operated by various driving methods, but generally, air driving type, electric driving type, and engine driving type are representative.
空気駆動式は、作動空気圧力によって吐出圧力が自動
的に設定され、吐出圧力は作動空気圧力とのバランスに
よって保たれる。従って、作動空気に見合った吐出圧力
に常に制御されていることになる。In the air driven type, the discharge pressure is automatically set by the working air pressure, and the discharge pressure is maintained by the balance with the working air pressure. Therefore, the discharge pressure is always controlled to match the working air.
これに対し、電動式、エンジン駆動式は圧力制御装置
を設け、最高吐出圧力時に駆動停止等の制御をし、一定
の圧力降下により再び駆動する等の制御をする必要があ
る。On the other hand, it is necessary to provide a pressure control device for the electric drive type and the engine drive type, control the drive stop at the maximum discharge pressure, and control the drive again with a constant pressure drop.
圧力の検知は、ピストンに受ける圧力をばねが受ける
荷重の変位として検知する方法やブルドン管式変位量で
検知する方法や歪ゲージ式圧力センサーで検知する方法
等がある。The pressure can be detected by detecting the pressure applied to the piston as the displacement of the load received by the spring, detecting it by the Bourdon tube displacement amount, or detecting it by a strain gauge type pressure sensor.
制御装置としてピストン式は、停止圧力と作動圧力を
受圧面積の変更による差圧で制御する方式である。又、
ブルドン管式は変位量の差によってアナログスイッチを
作動させるもので、また歪ゲージ式はセンサーからの信
号を処理して制御信号を出力させる方式が採られてい
る。The piston type as a control device is a system in which the stop pressure and the working pressure are controlled by the differential pressure by changing the pressure receiving area. or,
The Bourdon tube type operates an analog switch according to the difference in displacement amount, and the strain gauge type employs a method of processing a signal from a sensor and outputting a control signal.
また、圧力設定時に必要な圧力表示はブルドン管式圧
力計が用いられている。A Bourdon tube pressure gauge is used to display the pressure required when setting the pressure.
一般には、吹付け等の材料吐出が中断され、吐出圧力

前記駆動手段を遮断し、塗料圧送ポンプの運転を停止さ

復帰し、駆動手段を作動させて塗料圧送ポンプは再び作
動する。この時、断続を行なう圧力の範囲は通常断続圧
力と呼れ、固定されている。Generally, when the discharge of material such as spraying is interrupted and the discharge pressure reaches a set pressure, it is detected by one of the methods, and the control device shuts off the drive means by receiving a displacement and a signal due to the pressure, Stop the operation of the pressure pump. After that, when spraying or the like is started again, the discharge side pressure decreases. When the pressure drops to a certain level, the control device is restored, the drive means is activated, and the paint pressure pump is activated again. At this time, the range of pressure for interrupting is usually called an interrupting pressure and is fixed.
圧送ポンプにより高粘度材料の吐出を行い吹付ガンよ
り噴出させる場合、途中の管路の圧力降下は著しく、例
えばポンプ吐出圧力が100kg/cm2であっても吹付ガンで
は数kg/cm2に低下してしまうことも通常であり、従っ
て、この種のポンプは高圧ポンプが用いられる。When a high-viscosity material is discharged by a pressure pump and ejected from a spray gun, the pressure drop in the pipeline in the middle is significant.For example, even if the pump discharge pressure is 100 kg / cm 2 , the spray gun drops to several kg / cm 2 . It is also normal for this to happen, so that a pump of this type is a high-pressure pump.
＜発明が解決しようとする課題＞ しかし、前記ブルドン管式圧力計は塗料が詰まりやす

である材料（塗料）が高粘度である程大く影響する。<Problems to be Solved by the Invention> However, the Bourdon tube type pressure gauge is apt to be clogged with paint and causes malfunction and malfunction at an early stage. Also, when it is provided in the middle of the pipe, a pressure outlet is required, so a pipe joint such as a T-shaped joint is provided and a pressure gauge is mounted there. For this reason, steps, narrowed portions, corners, etc. are inevitably formed in the passage, leading to an increase in flow resistance. This has a greater effect as the material (paint) that is a fluid has a higher viscosity.
制御装置におけ断続圧力が固定の場合、ポンプから吐
出された材料は塗料ホースより吹付ガンに送られるが、
塗料の粘度が低い場合（例えば数100cp）、吹付ガンの
圧力と塗料圧送ポンプ出口部での圧力は比較的一定の圧
力降下割合で同調する。だが、高粘度の場合（例えば数
万cp）では流れの関係から吹付ガンの作動により吹付圧
力が低下しても塗料圧送ポンプ側の圧力低下は時間的に
遅れ、従ってポンプ駆動は継続し、次に吹付ガンを停止
した時には圧力は上昇し、塗料圧送ポンプの作動は停止
する前に再び運転制御となり、連続運転の状態を継続す
る。即ち、吹付ガンの断続吹付けがあっても、塗料圧送
ポンプは連続運転となり、吹付ガン付近の圧力は脈動が
起り、吹付のバラツキが生ずる。When the intermittent pressure is fixed in the controller, the material discharged from the pump is sent from the paint hose to the spray gun,
When the viscosity of the paint is low (for example, several hundred cp), the pressure of the spray gun and the pressure at the outlet of the paint pump are synchronized at a relatively constant pressure drop rate. However, in the case of high viscosity (for example, tens of thousands of cp), even if the spray pressure decreases due to the operation of the spray gun due to the flow, the pressure drop on the paint pressure pump side is delayed in time, so the pump drive continues and When the spray gun is stopped, the pressure rises, and the operation of the paint pump is again controlled before it stops, and the continuous operation state is continued. That is, even if there is intermittent spraying of the spray gun, the paint pressure pump continues to operate and the pressure in the vicinity of the spray gun pulsates, causing variations in spraying.
また、前記吐出圧力調整は、実際に塗料圧送ポンプに
塗材を送り込み加圧をしないと、圧力計を見ながらの設
定はできない。これは圧力表示が実際の加圧によって変
化表示するアナログタイプのブルドン管式圧力計を用い
ているからであり、調圧時の操作が極めて面倒であっ
た。Further, the discharge pressure adjustment cannot be set while looking at the pressure gauge unless the coating material is actually sent to the coating material pressure pump to apply pressure. This is because an analog type Bourdon tube type pressure gauge that changes the pressure display by actual pressurization is used, and the operation at the time of pressure adjustment was extremely troublesome.
本発明は上記実情に鑑み、歪ゲージ式圧力センサーを
塗料圧送ポンプの吐出管路中に直接配設し、流量抵抗を
極力小さくし、上記欠陥を一掃する塗料圧送ポンプを制
御装置を提供することを目的としたものである。In view of the above situation, the present invention provides a control device for a paint pressure pump that disposes a strain gauge type pressure sensor directly in the discharge conduit of the paint pressure pump to minimize the flow resistance and eliminates the above defects. It is intended for.

るものである。<Means for Solving the Problems> In the present invention, a high-viscosity paint is pressure-fed by a paint pressure pump to a spray gun for intermittent spraying, and the paint pressure pump stops driving at a preset discharge pressure. In a pressure control device for a paint pump which is driven again by the decrease of the discharge pressure and maintains the discharge pressure within a set pressure range, a discharge pipe disposed between the paint pressure pump and the spray gun. A strain gauge type pressure sensor is directly provided in a flat manner, and the pressure sensor is used as a control pressure detection means and also as a pressure display means, and the control pressure can be adjusted in the same manner as a previously adjustable target pressure. It has a pressure setting circuit for setting the intermittent pressure difference.

A digital display for each of the, and a comparison circuit for comparing the signal from the pressure setting circuit set according to the target pressure, the control circuit for outputting the result and the output signal from the control circuit It is provided with a power transmission device for cutting off the drive.

を適宜行うものである。<Operation> Due to the above configuration, the paint (coating material) discharged from the engine-driven pump by the operation of the spray gun flows and sprays through the discharge pipes and hoses, but is discharged by intermittent spraying. When the pressure reaches the set pressure, the drive source is intermittently connected accordingly.

である。In this case, the discharge pressure is detected by a strain gauge type pressure sensor, but the pressure sensor is flatly arranged directly in the discharge pipe without a special joint, etc. Even if a high-viscosity paint is used, it is not adversely affected. In addition, since the signal of this pressure sensor is digitally displayed via the control device, its state can be seen at a glance, and a power transmission device such as an electromagnetic clutch that shuts off the power source under a predetermined pressure can be set according to the target pressure. It operates with the control signal output according to the result of the comparison circuit that compares it with the signal from the set pressure setting circuit, causing a time delay due to the pressure drop on the pump side even during repeated intermittent use of the spray gun. Instead, the pressure in the vicinity of the spray gun does not pulsate, and smooth spraying is possible.

る。<Effects of the Invention> As described above, the controller for the paint pressure pump of the present invention is
The strain gauge pressure sensor is directly installed in the discharge pipe between the paint pressure pump and the spray gun, so it is compact and clean, and the resistance inside the pipe is greatly reduced compared to the conventional one. Therefore, particularly in the case of a high-viscosity coating material, pressure loss is small and pulsation is reduced. Further, the coating material stays in the pipe, clogging, etc. are eliminated, and the cleaning property is good, so that the pipe can always be used in a correct state, and the resistance in the pipe line does not gradually increase even in long-term use. Of course,
It does not cause disabling due to clogging of coating materials. Moreover,
When setting the target pressure, etc., the pressure can be set by adjusting the volume without actually sucking the coating material and pressurizing it. Furthermore, since the discharge pressure that is optimum for the coating material used can be maintained and the drive source can be interrupted, the lifespan of the drive device and the transmission device is extended, and there is an effect that wasteful disconnection is not caused by changing the interrupt pressure difference. .
