雑な機構を必要とする欠点があった。For example, when spraying a two-component paint consisting of a base agent and a curing agent with an airless spray gun, conventionally the two components were pumped separately using two pumps of the same type that mechanically kept the discharge amount constant. This method is used to maintain a constant mixing ratio by driving two plunger pumps simultaneously using a single reciprocating air motor.
Generally, a pumping device was used in which the mixing ratio was adjusted by adjusting the stroke ratio of the plungers of two pumps, but with this method, even if the properties of the base resin and curing agent were different, There is a restriction that pumps of the same type must be used, and a complicated mechanism is required to adjust the stroke ratio of the plungers of the two pumps.

C is a cleaning liquid pressure-feeding pipeline, and the main agent pressure-feeding pipeline A pumps up the base agent in the tank 1 with a plunger-type auxiliary pressure-feeding pump 2 to a storage tank 3 and pumps it with a plunger pump 4, and the hardening agent pressure-feeding pipeline B The curing agent in the tank 5 is pumped up into the storage tank 7 by a plunger-type auxiliary pressure pump 6, and the hardening agent is pumped by a gear pump 8, and pressure gauges 9 are installed at the terminals of each of the pressure feed pipes A and B. , IO1 on-off valve 11.12
and check valves 13 and 14 are interposed in sequence, check valves L3,
14 are connected to each other and connected to a static mixer 15, and a nozzle 16 with a small-diameter nozzle hole is provided at the outlet of the nozzle 16. The branch pipes branched into two are connected to the base agent pressure feed line A and the curing agent pressure feed line B via on-off valves 19 and 20, respectively, and the on-off valve 11 .12 and 19.20
are connected to each other so as to open and close in conjunction with each other.

・ＰｌとなりＰ】を一定に保つことによりＰｌが常に一
定に保たれるようになっている。In the plunger pump 4 of the main agent pressure feed line A, a plunger 43 is connected to a piston 42 of a reciprocating air motor 41 that is driven by pressurized air at a constant pressure supplied from a pressurized air supply source (not shown). piston 42
Let the area of A1. The area of the plunger 43 is A2. When the pressure of pressurized air is Pl, discharge pressure P2=AI/A2
・Pl becomes P] By keeping P] constant, Pl is always kept constant.

形成された空間に充満した液体を圧送するようにしたも
のであって。On the other hand, the gear pump 8 of the curing agent pressure feeding pipeline B has a pair of gears 82 that mesh with each other and rotate within the case 81.
．． 82 is connected to a constant speed motor 84 via a continuously variable transmission 83, and the liquid filled in the space formed between the pair of gears 82, 82 and the case 81 is pumped. .
歯車８２．８２同士及び歯車８２とケース８１の間で生
ずる漏れ量が無視し得る程度であれば、その吐出流量は
歯車８２．８２の回転速度に比例する。If the amount of leakage occurring between the gears 82, 82 and between the gears 82 and the case 81 is negligible, the discharge flow rate is proportional to the rotational speed of the gears 82, 82.

４の吐出流量をＱ ａ 、ギヤーポンプ８の吐出流量を
Ｑｂとすると、 Ｑ＝Ｑ ａ ＋Ｑ ｂとなる。Note that the flow rate Q and pressure P of the liquid discharged from a nozzle hole with an area of 1
Since the relationship Qoc S, /i'' holds true, the orifice area of the nozzle 16 can be determined by the discharge flow rate Q of the mixed liquid discharged from the nozzle 16 and the discharge pressure P required to obtain good atomization. S is determined, and if the discharge pressure is kept at a constant value P using the nozzle 16 with this area, the discharge flow rate of the mixed liquid is maintained at a constant value Q, and the discharge flow rate of the plunger pump 4 is also maintained at a constant value Q. When Q a and the discharge flow rate of the gear pump 8 are Qb, Q=Q a +Q b.
したがって、プランジャポンプ４の吐出圧力がＰとなる

うにその回転速度を調整すると、逆止弁１３．１４を押
し開いて合流し、スタティックミキサ１６で混合されて
ノズル１６から噴出する混合液の流量Ｑは一定であり、
しかも。Therefore, if the pressure of the pressurized air supplied to the air motor 41 is adjusted so that the discharge pressure of the plunger pump 4 becomes P, and the rotational speed is adjusted so that the discharge flow rate of the gear pump 8 becomes Qb, the opposite occurs. The flow rate Q of the mixed liquid that pushes open the stop valves 13 and 14 to merge, is mixed in the static mixer 16, and is ejected from the nozzle 16 is constant,
Moreover.
プランジャポンプ４によって吐出される主剤の流量Ｑａ
＝Ｑ−Ｑｂも必然的に一定となるから、主剤と硬化剤の
混合比Ｑ ａ ／ Ｑ ｂは一定に維持されるのである
。Flow rate Qa of the base agent discharged by the plunger pump 4
Since =Q-Qb is also necessarily constant, the mixing ratio Q a /Q b of the main agent and curing agent is maintained constant.

あるから、主剤の吐出流量は硬化剤の増加分だけ減少し
、または、減少分だけ増加して混合比が変化するのであ
る。When adjusting the mixing ratio, changing the rotational speed of the gear pump 8 using the continuously variable transmission 83 changes the discharge flow rate of the curing agent, but since the discharge flow rate Q of the mixed liquid is constant, the main agent The discharge flow rate decreases by the amount of the hardening agent, or increases by the amount of the decrease, and the mixing ratio changes.
噴射を休止するときは、開閉弁１１．１２を閉じ、他方

出し、管路中の残留塗料を排出して硬化を防止する。When stopping the injection, the on-off valve 11.12 is closed and the other on-off valve 19.20 is opened to supply the cleaning liquid to the pressure feeding pipes A and B for the main agent and curing agent and discharge it from the nozzle 16. Prevents curing by discharging residual paint in pipes.
前記において、プランジャポンプ４は、吐出流量の変動
にかかわらず吐出圧力を一定に保つものであり、また、
ギヤーポンプ８は吐出圧力の変動にかかわらずに吐出流
量を一定に保つものであって、このような機能を有する
ものであれば、他の形式のポンプを使用してもよい。In the above, the plunger pump 4 maintains the discharge pressure constant regardless of fluctuations in the discharge flow rate, and
The gear pump 8 keeps the discharge flow rate constant regardless of fluctuations in the discharge pressure, and other types of pumps may be used as long as they have this function.
