【考案の詳細な説明】
本考案は、処理液循環方式の自動現像機に関し、特に棒
状ヒータを現像機処理槽内に設置して処理液を直接加熱
する構造の自動現像機に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic developing machine using a processing liquid circulation system, and more particularly to an automatic developing machine having a structure in which a rod-shaped heater is installed in a processing tank of the developing machine to directly heat the processing liquid.
一般に、自動現像機は、処理性の安定を目的として、処
理液循環方式を採用している。Generally, automatic processors employ a processing liquid circulation system for the purpose of stabilizing processing performance.
すなわち、処理液の均等化と、処理液の温度の均等化が
、処理液の循環によってなされている。That is, equalization of the processing liquid and equalization of the temperature of the processing liquid are achieved by circulating the processing liquid.
自動現像機で処理液は、３５°Ｃ前後に維持して処理を
行うことが多いので、ヒータと感温部（センサ）を用い
て液温を一定に維持することがなされている。In automatic developing machines, the processing solution is often maintained at around 35° C., so a heater and a temperature sensing section (sensor) are used to maintain the solution temperature constant.
第１図は、現在多く用いられている熱交換器方式の自動
現像機の断面図である。FIG. 1 is a sectional view of a heat exchanger type automatic developing machine that is currently widely used.
処理槽１内の処理液は、配管２によってヒータ３および
センサ４を内臓した熱交換器５と液体ポンプ６とを通っ
て循環する形式のものである。The processing liquid in the processing tank 1 is circulated through a heat exchanger 5 containing a heater 3 and a sensor 4 and a liquid pump 6 via piping 2 .
この熱交換器方式のものは、自動現像機の外部に広い配
管スペースが必要であることと、熱交換器部５からの放
熱等で熱効率が悪い欠点をもっている。This heat exchanger type has the drawbacks that a large piping space is required outside the automatic developing machine and that thermal efficiency is low due to heat radiation from the heat exchanger section 5, etc.
これらの欠点を除くために、第２図に示すような、ヒー
タ３を現像機処理槽１内に設置して処理液を直接加熱す
る循環方式の自動現像機の断面図である。In order to eliminate these drawbacks, this is a sectional view of a circulation type automatic developing machine in which a heater 3 is installed in the developing machine processing tank 1 to directly heat the processing liquid as shown in FIG.
ヒータ３は内部にニクロム線等を内蔵し、表面積を多く
とって放熱性をよくするために、棒状のものを多く使用
している。The heater 3 contains a nichrome wire or the like inside, and is often rod-shaped in order to have a large surface area and improve heat dissipation.
第２図のように処理液の排出口の近くにヒータ３を設置
すると、処理液はＳで示したような流線を形成しながら
循環することとなる。If the heater 3 is installed near the outlet of the processing liquid as shown in FIG. 2, the processing liquid will circulate while forming a streamline as shown by S.
ヒータ３の３ａ部分では処理液の流速が高いので、ヒー
タ３の３ａ部分の表面温度は実測すると５０′Ｃ程度を
示していた。Since the flow rate of the processing liquid was high in the portion 3a of the heater 3, the surface temperature of the portion 3a of the heater 3 was actually measured to be about 50'C.
これに反してヒータ３の３ｂ部分は処理液の流速も低く
、３ｂ部分の表面温度は実測すると８０Ｃ程度となって
いた。On the other hand, the flow rate of the processing liquid in the portion 3b of the heater 3 was low, and the surface temperature of the portion 3b was actually measured to be about 80C.
このようにヒータ３の表面温度が高いと、処理液の加熱
劣化が促進されることが判明している。It has been found that when the surface temperature of the heater 3 is high as described above, heating deterioration of the processing liquid is accelerated.
例えば、現像液についてみると、現像液中の硬膜剤の劣
化があられれて、このような現像液で処理したフィルム
は含水量が増えて、乾燥性が悪くなるような欠点があら
れれる。For example, when it comes to developing solutions, the hardening agent in the developing solution deteriorates, and films treated with such developing solutions have an increased moisture content, resulting in poor drying properties.
本考案は、ヒータ表面の流速をあげて処理液の加熱劣化
を防止する目的でなされたもので、棒状ヒータを現像機
処理槽内に設置して処理液を直接加熱する処理液循環方
式の自動現像機において、上記棒状ヒータの長子方向に
沿って上記処理液が流線を形成するように規制板を設け
たことを特徴とする自動現像機を提供するものである。This invention was developed for the purpose of increasing the flow rate on the surface of the heater to prevent heat deterioration of the processing solution.It is an automatic processing solution circulation method in which a rod-shaped heater is installed in the processing tank of the developing machine to directly heat the processing solution. The present invention provides an automatic developing machine, characterized in that a regulating plate is provided so that the processing liquid forms a streamline along the longitudinal direction of the rod-shaped heater.
第３図は、本考案の実施例を示したもので、ヒ−タ３を
取付台７によって処理槽１の内壁に取り付け、新たに規
制板８を設けた。FIG. 3 shows an embodiment of the present invention, in which a heater 3 is attached to the inner wall of the processing tank 1 using a mounting base 7, and a regulating plate 8 is newly provided.
規制板８を設けたことによって、循環する処理液の流線
Ｓは棒状ヒータ３の長手方向に沿って形成するようにし
た。By providing the regulating plate 8, the streamline S of the circulating processing liquid is formed along the longitudinal direction of the rod-shaped heater 3.
このようにすると、ヒータ３表面の流速は一様に高くな
り、局部的にヒータ３表面の温度が上昇するのを防止す
る効果があり゛、長時間循環処理を行っても、処理液の
加熱劣化が殆んど認められなかった。In this way, the flow velocity on the surface of the heater 3 becomes uniformly high, which has the effect of preventing the temperature on the surface of the heater 3 from rising locally. Almost no deterioration was observed.
