【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、送液接続構造に係り、一般には実質的に縦
向きに連結され、上流の第２管路に対して下流の第１管
路端部が挿入された接続構造に関する。Description: BACKGROUND OF THE INVENTION The present invention relates to a liquid feed connection structure, generally connected substantially vertically, and a first pipe downstream from an upstream second pipe. The present invention relates to a connection structure in which a road end is inserted.
第２図のように、液の管路に関して、縦向きに連結さ
れた第１管路１および第２管路２を有し、下方の第２管
路２に対して上方の第１管路１端部が挿入された接続構
造が知られている。As shown in FIG. 2, a first conduit 1 and a second conduit 2 which are vertically connected to each other with respect to a liquid conduit, and an upper first conduit with respect to a lower second conduit 2. A connection structure in which one end is inserted is known.
この場合、第１管路１の端面は、単に直角に切断され
たままの形状である。In this case, the end face of the first conduit 1 has a shape simply cut at a right angle.
しかるに、かかる接続構造においては、第２図のよう
に、液に混入した気泡Ｂが、送液を停止した場合などに

ことが度々ある。また、送液時、先頭液面が第１管路１
液面が空気を巻き込み泡を発生させる場合が多い。この
場合、当該液がたとえば感光材料であるときは、記録ム
ラとなり、大きな品質上の問題となる。However, in such a connection structure, as shown in FIG. 2, the bubbles B mixed in the liquid float when the liquid supply is stopped or the like, and are caught on the end face of the first pipe 1 to supply the liquid later. Occasionally, the bubbles are often mixed into the next liquid. Also, at the time of liquid feeding, the head liquid level is the first line 1
The liquid surface often entrains air and generates bubbles. In this case, when the liquid is, for example, a photosensitive material, recording unevenness occurs, which causes a large quality problem.
従来、かかる事態を回避するために、各管路１、２が
可撓性材料からなるときは、第２図のように、第２管
路２の途中を圧潰および解放を繰り返して、液を流動化

新たな液の送給の際に大流量の液を流して、その液に泡
Ｂを同伴させるか、さらには第２管路２以降に脱泡装
置を付加するなどの手段を講じていた。Conventionally, in order to avoid such a situation, when each of the pipes 1 and 2 is made of a flexible material, the middle of the second pipe 2 is repeatedly crushed and released as shown in FIG. Either make the foam float on the liquid surface by fluidizing and defoam,
At the time of feeding a new liquid, a large flow rate of the liquid is caused to flow, and the liquid is accompanied by bubbles B, or a defoaming device is provided after the second pipe 2.
しかし、前記およびの方法では、手間がかかる、
さらにの方法では、第２管路が可撓性のもののみしか

方法では、余分な液を使用することになり不経済である
との欠点がある。他方、の方法では設備費が嵩む難点
がある。However, the above method and the above method are troublesome,
In a further method, there is a limitation that only the second conduit is flexible, and the second conduit is damaged by crushing and releasing the second conduit. There is a disadvantage that the use of a liquid is uneconomical. On the other hand, the other method has a disadvantage that the equipment cost increases.
したがって、本発明の主たる課題は、特別な手段を構
じることを避け、しかも確実に脱泡を図ることにある。Therefore, a main object of the present invention is to avoid special means and to surely remove bubbles.
上記課題は、それぞれ縦向きに配置され、下側の第２

決できる。The above tasks are arranged vertically, and the second
In the connection structure in which the upper end of the first conduit is inserted into the conduit, a taper is formed on the inner surface of the lower end of the first conduit, and the taper angle θ with respect to the cross section of the conduit is 10 degrees or more. The problem can be solved by setting the thickness t of the lower end surface to 0.5 mm or less.
なお、本発明は、第１管路または第２管路の一方が継
手であることを当然に含む。Note that the present invention naturally includes that one of the first conduit and the second conduit is a joint.
本発明に従って、第１管路の下端内面にテーパーを形
成すると、液中に混入した泡が浮上したとき、第１管路
下端面にトラップすることなく、テーパーに沿って浮上
し、液面において脱泡が図られる。According to the present invention, when a taper is formed on the inner surface of the lower end of the first conduit, when bubbles mixed into the liquid float, they float along the taper without being trapped on the lower end surface of the first conduit, and at the liquid surface, Defoaming is achieved.
以下本発明を第１図を参照しながら実施例によりさら
に詳説する。Hereinafter, the present invention will be described in more detail with reference to an embodiment with reference to FIG.
本発明では、第１図のように、第１管路１の下端内面
にテーパー部1aが形成され、その第１管路１の横断面に
対するテーパー角度θが10度以上であり、しかも下端面
の肉厚ｔが0.04〜0.5mmとされる。In the present invention, as shown in FIG. 1, a tapered portion 1a is formed on the inner surface of the lower end of the first conduit 1, the taper angle θ with respect to the cross section of the first conduit 1 is 10 degrees or more, and the lower end surface Has a thickness t of 0.04 to 0.5 mm.

接続の際に手を傷付ける虞れがある。Is preferably 45 degrees or more, and more preferably 60 degrees or more. The thickness t of the lower end face of the first conduit 1 is preferably 0.1 mm or less. The lower limit is set to 0.04 mm. If the thickness t of the lower end surface is too small, there is a possibility that the hand may be damaged during connection.

ラーネガ用写真感光材料乳剤などに対して有効である。The materials of the first conduit 1 and the second conduit 2 are not limited as in the conventional example. Although the viscosity of the target liquid is not limited, the effect of the present invention is remarkably exhibited for a liquid having a high viscosity, a liquid having a viscosity of 5 cp or more, and particularly a liquid having a viscosity of about 12 to 25 cp. The type of liquid is effective for a gelatin liquid, a color negative photographic light-sensitive material emulsion, and the like.
以下実施例を示し、本発明の効果を明らかにする。 Examples are shown below to clarify the effects of the present invention.

た。In a state where the pipe having such a connection structure is inclined at 23 degrees with respect to the vertical line, a 6% gelatin solution having a viscosity of 17 cp is used.
The liquid was sent at a rate of 10 cc / min. At the time of this liquid feeding, there is no phenomenon in which the head liquid level entrains air at the end of the first conduit to generate bubbles, the bubbles remain at the lower end of the first conduit, and the bubbles of visible bubbles in the supplied liquid are reduced. No unevenness was seen.
