Description of the Related Art For example, a two-component mixing dispenser is usually used when a main component of a two-component mixing curing type resin and a curing agent are mixed and supplied at a predetermined ratio. As the two-liquid mixing dispenser, a gear pump type, a pneumatic type, a tube deformation type, etc. are known depending on the type of pump.

まい、所期の特性が得られなくなる場合がある。In the conventional two-liquid mixing dispenser, the main agent and the curing agent are metered and supplied by a pump. However, during operation for a long time, the main agent and the curing agent may be deteriorated due to wear of parts and other factors. The supply amount of the curing agent may change, and the conventional dispenser cannot detect the change in the supply amount. Therefore, the mixture ratio of the main agent and the curing agent may change during long-time operation, and the desired characteristics may not be obtained.

However, the flow meter can perform accurate measurement if the flow of the liquid is stable, but it is difficult to measure the flow rate accurately when the liquid intermittently flows by a fixed amount like a dispenser.

In the case of mixing and discharging with, the supply pressures of the two liquids are also kept constant. However, if the mixing ratio changes,
Since the viscosity of the mixed liquid changes, the supply pressure of the two liquids changes. Therefore, the pressure at the proper mixing ratio is measured by the pressure detector, and if the subsequent pressure fluctuation is monitored with reference to the pressure, it is detected whether the mixing ratio of the two liquids has changed. It becomes possible.

000cps である。With this dispenser, the main component for the two-component mixed curing type epoxy resin and the curing agent were mixed and discharged. The viscosity of the main agent supplied from the main agent tank 11 is 8000 cps, the viscosity of the curing agent supplied from the curing agent tank 15 is 80 to 100 cps, the proper mixing ratio is the main agent: hardening agent = 100: 7, and the viscosity when mixed is 4
It is 000cps.

圧力が０kgf/cm2 G になるまでの時間はＴ2 である。The pressure behavior detected by the pressure detectors 35 and 37 at this time is shown in FIG. (A) shows continuous ejection, and (B) shows intermittent ejection. That is, the pressure during continuous discharge is P 1 when the mixing ratio is appropriate, and the maximum pressure during intermittent discharge is P 2 ,
The time required for the pressure to reach 0 kgf / cm 2 G is T 2 .

The shot ejection time becomes shorter than T 2 . This is because a large amount of a low-viscosity curing agent is added, the viscosity of the mixture is reduced, and the liquid is easily drained at the nozzle.

力が立上がりやすくなるためである。Next, FIG. 4 shows the pressure behavior when the mixing ratio of the main agent: hardening agent was changed to 100: 5. (A) The pressure becomes higher than P 1 during continuous discharge, and (b) the maximum pressure becomes higher than P 2 during intermittent discharge and the discharge time becomes longer than T 2 . This is because the curing agent having a low viscosity decreases, the viscosity of the mixture increases, and the pressure easily rises at the nozzle.

よびノズル部ではヒーターと温度調整器により混合物の
温度を一定に保つことが望ましい。When the two liquids are mixed with the dispenser shown in FIG. 1, the viscosity of the base resin and the curing agent is extremely important, and therefore it is desirable to perform them in a constant temperature chamber. Further, in the mixer and the nozzle section, it is desirable to keep the temperature of the mixture constant by using a heater and a temperature controller.
【００１７】実施例２ 実施例１は混合する２液の粘度が異なる場合であるが、
２液の粘度が同等の場合でも、混合時の化学反応により

る。Example 2 In Example 1, the two liquids to be mixed have different viscosities.
Even if the viscosities of the two liquids are the same, if heat generation or heat absorption occurs due to a chemical reaction during mixing, it is possible to check whether or not the mixing ratio is appropriate by pressure detection.
【００１８】その理由は、例えば発熱反応が起きる場
合、主剤に対する硬化剤の量が標準混合比より少ないと
きは発熱が少なく、混合物の粘度が高くなって圧力が上
昇し、逆に主剤に対する硬化剤の量が標準混合比より多

低下するからである。したがって２液の粘度が同等の場
合でも、混合時に発熱反応または吸熱反応が起きる場合
には、図１と同じ装置で混合比の変化を知ることができ
た。The reason is that, for example, when an exothermic reaction occurs, when the amount of the curing agent relative to the main agent is less than the standard mixing ratio, the heat generation is small, the viscosity of the mixture increases, and the pressure rises. When the amount is larger than the standard mixing ratio, a large amount of heat is generated, the viscosity of the mixture becomes low, and the pressure drops. Therefore, even if the viscosities of the two liquids are the same, if the exothermic reaction or endothermic reaction occurs during mixing, it was possible to know the change in the mixing ratio with the same device as in FIG.
【００１９】実施例３ 次に２液の粘度が同等で、混合時に発熱反応も吸熱反応

ーと同じである。Example 3 Next, when the two liquids have the same viscosity and neither exothermic reaction nor endothermic reaction occurs during mixing, either one of the main agent and the curing agent is heated or cooled to forcibly change the viscosity. By doing so, it is possible to detect a change in the mixing ratio as in the first embodiment. The structure of the two-liquid mixing dispenser at this time is shown in FIG. In this dispenser, a heater or a cooling pipe 39 is provided in the curing agent supply path to heat or cool the curing agent so that the viscosity of the curing agent is different from that of the main agent. The other structure is the same as the dispenser of FIG.

できる。In the above embodiments, the case where the change in the mixing ratio of the main agent and the curing agent is detected has been described. However, by using the dispenser of the present invention, it is possible to detect other abnormality of the dispenser. For example, when the mixing ratio does not change but the amounts of the main agent and the curing agent increase or decrease at the same ratio, pressure fluctuations occur due to an increase or decrease in the discharge amount, so that an abnormality can be detected. Further, when the mixture adheres to the mixer or the nozzle portion and hardens, the fluid resistance of the mixture increases, so that the pressure fluctuation also occurs and the abnormality can be detected.
