本発明は、樹脂の吐出量の制御方法及びその制御を行う
吐出装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for controlling the amount of resin discharged and a discharge device that performs the control.
（従来の技術）
従来、この種の装置は、第３図に示されるように、吐出
装置本体１からシリンジ３に圧縮された空気を送り込み
、その空気の圧力Ｐ及び加圧時間ｔにより液体の吐出量
を制御するようにしている。(Prior Art) Conventionally, this type of device, as shown in FIG. 3, sends compressed air from the dispensing device main body 1 to the syringe 3, and uses the pressure P of the air and the pressurization time t to generate liquid. The discharge amount is controlled.
一般に粘度及び管径が一定であれば、圧力Ｐ及び加圧時
間ｔによって、吐出量■が決定される。Generally, if the viscosity and pipe diameter are constant, the discharge amount (2) is determined by the pressure P and pressurization time t.
しかしながら、２液性接着剤のような時間と共に粘度ｎ
が変化する液体は、圧力Ｐ及び加圧時間ｔが一定の場合
でも、第４図に示されるように、吐出量■が指数関数的
に変化する。However, with time, the viscosity n
In the case of a liquid whose pressure changes, even when the pressure P and the pressurization time t are constant, the discharge amount ■ changes exponentially, as shown in FIG.
従って、必要とされる吐出量■１〜Ｖ２を得る方法とし
て、従来は予め、圧力Ｐ及び加圧時間ｔを設定しておき
、Ｔ’５−Ｔｚの間の時間内に吐き出し使用するという
方法をとっていた。Therefore, as a method to obtain the required discharge amount ■1 to V2, the conventional method is to set the pressure P and pressurization time t in advance, and discharge and use it within the time between T'5 and Tz. was taking.
しかし、この従来の方法では前記したように樹脂の吐出
時間がＴ１〜Ｔ２の間に定まり、つまり、１回について
の樹脂の使用時間が限定されること、また、Ｔ、〜Ｔ、
の時間内においても吐出量■が■１〜■２の間で変化す
るという欠点がある。However, in this conventional method, as described above, the resin discharge time is fixed between T1 and T2, that is, the resin usage time per one time is limited, and T, ~T,
There is a drawback that the discharge amount (2) changes between (1) and (2) even within the time period (2).
従来の他の方法として２液温合吐出装置を使用する方法
がある。Another conventional method is to use a two-liquid heating and discharging device.
これは、第５図に示されるように、２系統の同様の吐出
装置を使用し、一定の混合比でミキサ部ｍ内において混
合しながら吐き出しするものである。このことにより、
実時間で２液を混合できるので、吐出装置使用時間の粘
度変化は無視できる。As shown in FIG. 5, this uses two systems of similar discharge devices and discharges the mixture while mixing it in the mixer section m at a constant mixing ratio. Due to this,
Since the two liquids can be mixed in real time, changes in viscosity during the time the dispensing device is used can be ignored.
（発明が解決しようとする問題点）
しかしながら、本装置においては、第６図に示されるよ
うに、２液温合比が大きくなるに従い、最小吐出量が１
液吐出装置よりも太き（なり、微少量吐出には不都合で
ある。また、２液温合吐出装置は１液吐出装置に比べて
微少量を長時間かげて吐出する場合に硬化してしまう等
の格別の難しさを伴う。従って、従来より安全な方法と
して、予め２液を混合して１液とし、１液吐出装置を使
用することが一般に行われている。(Problems to be Solved by the Invention) However, in this device, as the two-liquid heating ratio increases, the minimum discharge amount decreases to 1.
It is thicker than a liquid dispensing device (which is inconvenient for dispensing very small amounts.Also, two-component heating dispensing devices harden when discharging minute amounts over a long period of time compared to single-component dispensing devices). Therefore, as a safer method than conventional methods, it is generally practiced to mix two liquids in advance to make one liquid and use a one-liquid discharging device.

この点について、以下、詳細に説明する。This point will be explained in detail below.
第４図は加圧時間が一定の場合の２液温合後の経過時間
Ｔによる吐出量の変化を示したものであるが、これは次
の式で表される。FIG. 4 shows the change in the discharge amount depending on the elapsed time T after the two liquids have warmed up when the pressurization time is constant, and this is expressed by the following equation.

That is, the pressurization time may be changed by the control device according to (5) 2 above. Since the above equation (6) does not include the factor of the elapsed time T, it is possible to easily control the discharge amount ■ by arbitrarily setting to.

In other words, the pressurization time t corresponding to the elapsed time T is stored in a table form in the memo January O, and the signal of the pressurization time t corresponding to the elapsed time T is sent to the main body of the dispensing device via the I10 interface. 12 and is sent to the timer 13 to control the pressurization time. Furthermore, the ejection conditions can be changed by appropriately inputting data from the MDI device depending on the resin to be ejected.
