おいて、めっき液に補給液を供給する手段としては定量
ポンプが使用されている。When using a plating solution, especially an electroless plating solution, metal salts, reducing agents, etc. are consumed in a short period of time, and the composition of the solution fluctuates rapidly. An automatic control device or method has been proposed (Japanese Patent Application Laid-open Nos. 53-44434 and 53-4563).
No. 1, No. 548123, etc.), but in these automatic control devices, a metering pump is used as a means for supplying replenishment liquid to the plating solution.

しかし、定量ポンプは、最近においてかなり精密なもの

しも満足し得ない上、定量設定操作、その制御にも常に
注意を払わなければならず、また定量設定操作の際にミ
スを伴なうおそれがあり、その扱いに問題がある。However, recently, quite precise metering pumps have been proposed, but these are expensive, and the ones that are commonly used tend to break down in the field, and their quantitative performance is not always satisfactory. Attention must always be paid to the quantitative setting operation and its control, and there is a risk of mistakes occurring during the quantitative setting operation, which poses problems in handling.

そして定量ポンプが故障したり、その定量設定操作にミ

の定量ポンプを設置しなければならず、非常に設備費が
高くなる等の欠点を有していた。In addition, especially when the plating tank is large and the amount of replenishment liquid required at one time is large, a large metering pump must be used or a large number of metering pumps must be installed, resulting in extremely high equipment costs. It had the following drawbacks.

本考案は上記欠点を除去したもので、常に確実に一定量
の補給液を供給することができ、取扱いも簡単で操作ミ
スを伴なうおそれも少なく、かつその構成も比較的簡単

作動させる。That is, in the measuring process of supplying and storing the replenishment liquid S into the cylinder 1, as shown in FIG. In response to a signal from the control device 17, the pump 5 is turned on when the on-off valves 4 and 8 are open (and the three-way control valve 11 is operated and the air conduit 10 and the air circulation pipe 14 are in communication with each other). Activate.

流れて補給液槽６内に戻されると共に、液位が更に上昇
し、液面感知計９の位置にまで到達すると、感知計９が
これを感知し、信号を発する。As a result, the replenishment liquid S in the replenishment liquid tank 6 is introduced into the measuring cylinder 1 through the replenishment liquid introduction pipe 3, and when the liquid level of the replenishment liquid S rises above the protruding end 7a of the overflow pipe 7,
When the liquid above the one protruding end 7a flows through the overflow pipe 7 and is returned to the replenishment liquid tank 6, the liquid level further rises and reaches the position of the liquid level sensor 9, when the sensor 9 detects this level. senses and emits a signal.

これにより、オーバーフロー管７の一端部７ａより上側
に存する補給液Ｓがこのオーバーフロー管７内を流れて
補給液槽６内に戻されることにより筒１内の液位が下降
し、オーバーフロー管７の一端部７ａ位置まで低下する
とオーバーフローが停止する。As a result, the replenishment liquid S existing above the one end 7a of the overflow pipe 7 flows through the overflow pipe 7 and is returned to the replenishment liquid tank 6, thereby lowering the liquid level in the cylinder 1 and lowering the liquid level in the overflow pipe 7. When the pressure drops to the position of one end 7a, overflow stops.

必要とした際に発せられるようになっている。The operation command from the control device 17 to the air pump 12 is issued when the control device 17 receives a signal such as a limit switch that operates every time the object to be plated moves in and out of the plating tank 16, or when the concentration of the plating solution is changed. When the control device 17 receives the electric signal of the plating liquid automatic control device that automatically senses and emits an electric signal at a predetermined concentration, or when the amount of replenishment liquid S per unit time is determined in advance. If there is, it is emitted at predetermined time intervals, and generally speaking, it is emitted when the plating solution P needs to be replenished.

される。When the liquid level of the replenishment liquid S in the cylinder 1 drops to the position of the one end 15a of the replenishment liquid supply pipe 15 by supplying the replenishment liquid S into the plating tank 16, the air is removed from the one end 15a of the replenishment liquid supply pipe 15.
It flows into this pipe 15 from 5a and is discharged to the atmosphere from the other end.

そしてこの補給液供給管１５他端からの放出が生じた後

供給管１５の一端部１５ａとの間の液量が確実にめっき
槽１６内に供給され、常に一定量の補給液Ｓがめつき液
Ｐに補給される。Therefore, in the process of replenishing the replenishment liquid to the plating tank 16, the amount of liquid between the protruding one end 7a of the overflow pipe 7 and the one end 15a of the replenishment liquid supply pipe 15 is always reliably supplied into the plating tank 16. A fixed amount of replenishment liquid S is always supplied to the plating liquid P.

この補給工程後、上述した計量工程が繰返えされ、かく
してめっき液Ｐへの補給液の定量補給が遠戚される。After this replenishment step, the above-mentioned metering step is repeated, and thus quantitative replenishment of the replenishment solution to the plating solution P is achieved.

限られず、例えば第３図に示すように側方に向けて連通
ずるようにしてもよい。In the above embodiment, one end of the overflow pipe 7 is directed upward and communicated with the inside of the measuring tube 1, but the present invention is not limited to this. For example, as shown in FIG. Good too.

The pump that introduces the replenishment liquid S from the replenishment liquid tank 6 into the cylinder 1 also includes:
It is not limited to the suction pump 5, but can be any air pump that sucks the air in the cylinder 1 by its operation to reduce the pressure inside the cylinder 1, thereby sucking up the replenishment liquid S in the replenishment liquid tank 6 through the replenishment liquid introduction pipe 3. In this case, this air pump can also be used as the air pump 12 for supplying compressed air into the cylinder 1, and other configurations can be changed without departing from the gist of the present invention. No problem.

供給するよう構成したことを特徴とするものである。As explained above, the present invention includes a replenishment liquid measuring cylinder 1, a replenishment liquid introduction pipe 3 whose one end communicates with the inside of the cylinder 1, an overflow pipe 7 whose one end communicates with the inside of the cylinder 1, and the introduction pipe 3.
means for introducing the replenishment liquid S of the replenishment liquid tank 6 into the cylinder 1 through the inside thereof, and means for supplying compressed air into the cylinder 1 when the plating solution P requires replenishment; A replenishment liquid supply pipe 15 is provided below one end of the overflow pipe 7 and communicates with the inside of the cylinder 1, and the replenishment liquid tank 6 is provided while the supply of compressed air into the cylinder 1 is stopped.
The replenishment liquid S in the cylinder 1 is introduced into the cylinder 1, and the liquid level of the replenishment liquid S in the cylinder 1 reaches the one end 7 of the overflow pipe 7.
a, the introduction of the replenishing liquid S into the cylinder 1 is stopped, and the replenishing liquid S existing above one end 7a of the overflow pipe 7 is discharged from the overflow pipe 7 to the outside of the cylinder 1. The present invention is characterized in that the replenishment liquid S stored in the replenishment liquid supply pipe 15 is supplied into the plating solution P through the replenishment liquid supply pipe 15 under the pressure of compressed air.

。Therefore, in the process of measuring the replenishment liquid S into the measuring cylinder 1 in this way, the replenishment liquid in the cylinder 1 is overflowed and discharged from the one end 7a of the overflow pipe 7 and outside the cylinder 1. The liquid level is always maintained at the position of one end 7a of the overflow pipe 7, so that a certain amount of replenishment liquid below this one end 7a is always reliably measured and stored.

また、筒１内の補給液Ｓをめっき液Ｐに補給する工程に
おいて、圧搾空気の圧力で常に導入管３の一端部３ａと
補給液供給管１５の一端部１５ａとの間の液量がめつき
液Ｐに供給され、一定量の補給液Ｓが常に確実にめっき
液Ｐに補給される。In addition, in the process of replenishing the plating solution P with the replenishment solution S in the cylinder 1, the amount of liquid between the one end 3a of the introduction pipe 3 and the one end 15a of the replenishment solution supply pipe 15 is constantly reduced by the pressure of compressed air. A fixed amount of the replenishing liquid S is supplied to the plating liquid P, and the plating liquid P is always reliably replenished with a certain amount of the replenishing liquid S.

５内に補給液を残すことなく、常に一定量の補給液を供
給できる。In this case, if you use a metering pump to directly supply the replenishment solution in the replenishment solution tank to the plating solution, if the metering pump stops operating, the metering pump will be placed between the metering pump and the plating solution being replenished. Replenishment liquid often remains in the tube 1, which causes measurement errors and errors in the supply amount of replenishment liquid.In the present invention, compressed air is supplied into the cylinder 1 and
Since the replenishment liquid is supplied through the pipe 5, this supply pipe 1
A constant amount of replenishment liquid can always be supplied without leaving any replenishment liquid in the tank.

また、圧搾空気をめっき液Ｐに対する補給液供給手段と
して用いているので、補給されるめっき液Ｐの存する位
置が計量筒１の設置位置よりかなり高いところにあって
も補給が確実に行なわれる。Further, since compressed air is used as a replenishment liquid supply means for the plating solution P, even if the plating solution P to be replenished is located at a location considerably higher than the installation position of the measuring tube 1, replenishment can be performed reliably.

更に、取扱いも簡単で操作ミスを伴なうおそれも少なく
、かつ構成も比較的簡単で安価に製作し得る等の利点を
有する。Further, it has advantages such as being easy to handle and less likely to cause operational errors, and having a relatively simple structure and being able to be manufactured at low cost.
