Description
本発明は、複数の現像機のタンクに純水等の液体を補充する現像機用送液装置に関するものである。 The present invention relates to a liquid feeder for a developer that replenishes a tank of a plurality of developers with a liquid such as pure water.
従来、写真フィルムや印画紙等の感光材料を処理液の充填された処理タンク内を通過させて自動的に現像処理する現像機としては、例えば、特許文献１がある。この特許文献１の現像機は、稼動状態において処理液中の水分が蒸発して液濃度が濃くなったとき、処理タンク内に純水を補充して処理液の濃度を適正な値に維持するための給水タンクを内蔵している。 Conventionally, as a developing machine for automatically developing a photosensitive material such as a photographic film or photographic paper through a processing tank filled with a processing solution, there is, for example, Patent Document 1. In the developing machine of Patent Document 1, when the water in the processing liquid evaporates and the liquid concentration becomes high in the operating state, the processing tank is replenished with pure water to maintain the processing liquid concentration at an appropriate value. It has a built-in water tank.
しかしながら、特許文献１の現像機を複数使用する場合には、各現像機がそれぞれ給水タンクを内蔵しており、これらの給水タンク内の水量をそれぞれ個別に管理する必要がある。このため、各給水タンク内の水量をそれぞれ検知するためのセンサー等が必要になり、設備のコストアップに繋がる。 However, when using a plurality of developing machines disclosed in Patent Document 1, each developing machine has a built-in water supply tank, and the amount of water in these water supply tanks must be individually managed. For this reason, a sensor or the like for detecting the amount of water in each water supply tank is required, leading to an increase in the cost of the equipment.
本発明は上記事実を考慮し、低コストで複数の現像機に液体を供給可能な現像機用送液装置を得ることを課題とする。 In view of the above-described facts, an object of the present invention is to obtain a developer feeding device capable of supplying liquid to a plurality of developing machines at low cost.
請求項１に記載の発明の現像機用送液装置は、液体が貯留されるメインタンクと、前記メインタンクに設けられ、水位を検出する水位検出部材と、複数の現像機のそれぞれに設けられたサブタンクと前記メインタンクとを水位が同一となるように連結する送液管と、を有する。 According to a first aspect of the present invention, there is provided a liquid feeder for a developing machine, which is provided in each of a plurality of developing machines, a main tank that stores liquid, a water level detection member that is provided in the main tank and detects a water level. And a liquid feed pipe for connecting the sub tank and the main tank so that the water levels are the same.
請求項１に記載の発明の現像機用送液装置では、液体が貯留されるメインタンクに設けられた水位検出部材によってメインタンク内の水位を検出することで水量を管理する。また、複数の現像機のそれぞれに設けられた各サブタンクは、メインタンクと送液管によって連結されており、サイフォンの原理によって、各サブタンクとメインタンクとの水位が同一となる。従って、水位検出部材で、メインタンクの水位のみを管理することで、同時に、複数のサブタンクの水量を管理することができる。この結果、低コストで複数の現像機に純水等の液体を供給することが可能になる。 In the liquid feeder for a developing machine according to the first aspect of the present invention, the amount of water is managed by detecting the water level in the main tank by a water level detecting member provided in the main tank in which the liquid is stored. In addition, each sub tank provided in each of the plurality of developing machines is connected by a main tank and a liquid feeding pipe, and the water level of each sub tank and the main tank becomes the same by the principle of siphon. Therefore, by managing only the water level of the main tank with the water level detection member, it is possible to simultaneously manage the water amounts of the plurality of sub tanks. As a result, it is possible to supply liquid such as pure water to a plurality of developing machines at low cost.
請求項２に記載の発明は請求項１に記載の現像機用送液装置において、前記送液管は、前記メインタンクに連結された本管と、前記本管から分岐され前記本管と前記サブタンクを連結する分岐管と、を有する。 According to a second aspect of the present invention, in the liquid feeding device for a developing device according to the first aspect, the liquid feeding pipe includes a main pipe connected to the main tank, a main pipe branched from the main pipe, and the main pipe and the main pipe. And a branch pipe connecting the sub tank.
請求項２に記載の発明の現像機用送液装置では、メインタンクに連結された本管から分岐された分岐管が本管とサブタンクを連結している。従って、メインタンクと各サブタンクとをそれぞれ個別の独立した送液管で連結する場合に比べて、総配管長が短くなる。 According to the second aspect of the present invention, the branch pipe branched from the main pipe connected to the main tank connects the main pipe and the sub tank. Therefore, the total pipe length is shorter than in the case where the main tank and each sub tank are connected to each other by independent liquid feeding pipes.
請求項３に記載の発明は請求項１又は請求項２に記載の現像機用送液装置において、前記複数のサブタンクに接続される各送液管の流水抵抗は、前記メインタンクからの流路長が長いほど小さくされている。 According to a third aspect of the present invention, in the liquid feeding device for a developing device according to the first or second aspect, the flow resistance of each liquid feeding pipe connected to the plurality of sub tanks is a flow path from the main tank. The longer the length, the smaller.
請求項３に記載の発明の現像機用送液装置では、メインタンクからの流路長が長いサブタンクに接続される送液管の流水抵抗を、メインタンクからの流路長が短いサブタンクに接続される送液管の流水抵抗に比べて小さくすることで、流路長が異なるために生じる送水時間の差による各サブタンク毎の水位差が生じにくくなる。 In the liquid feeding device for a developing machine according to claim 3, the flow resistance of the liquid feeding pipe connected to the sub tank having a long flow path length from the main tank is connected to the sub tank having a short flow path length from the main tank. By making it smaller than the flowing water resistance of the liquid feeding pipe, the difference in the water level for each sub-tank due to the difference in the water feeding time caused by the different flow path lengths is less likely to occur.
請求項４記載の発明は、請求項３に記載の現像機用送液装置において、前記流水抵抗は、前記送液管の内径を変えること又は前記サブタンクに形成された流入口の開口面積を変えることにより変える。 According to a fourth aspect of the present invention, in the liquid feeding device for a developing machine according to the third aspect, the flow resistance changes the inner diameter of the liquid feeding pipe or the opening area of the inlet formed in the sub tank. It changes by things.
請求項４記載の発明の現像機用送液装置では、送液管の内径を変えること又はサブタンクに形成された流入口の開口面積を変えることにより各サブタンクに接続される各送液管の流水抵抗を変える。従って、簡単な構成で、流路長が異なるために生じる送水時間の差による各サブタンク毎の水位差が生じにくくなる。 According to a fourth aspect of the present invention, there is provided a liquid feeder for a developing machine, wherein the water flow of each liquid feed pipe connected to each sub tank is changed by changing the inner diameter of the liquid feed pipe or by changing the opening area of the inlet formed in the sub tank. Change the resistance. Accordingly, with a simple configuration, a difference in water level for each sub-tank due to a difference in water supply time caused by different flow path lengths is less likely to occur.
請求項１に記載の本発明の現像機用送液装置は、上記構成としたので、低コストで複数の現像機に液体を供給できる。 Since the liquid feeding device for a developing machine according to the first aspect of the present invention has the above-described configuration, the liquid can be supplied to a plurality of developing machines at a low cost.
請求項２に記載の本発明の現像機用送液装置は、上記構成としたので、総配管長を短くできる。 Since the liquid feeding device for a developing machine according to the second aspect of the present invention has the above configuration, the total pipe length can be shortened.
請求項３に記載の本発明の現像機用送液装置は、上記構成としたので、流路長が異なるために生じる送水時間の差による各サブタンク毎の水位差を生じにくくできる。 Since the liquid feeding device for a developing machine according to the third aspect of the present invention has the above-described configuration, it is difficult to cause a difference in water level for each sub-tank due to a difference in water feeding time caused by a difference in flow path length.
請求項４に記載の本発明の現像機用送液装置は、上記構成としたので、簡単な構成で流路長が異なるために生じる送水時間の差による各サブタンク毎の水位差を生じにくくできる。 Since the liquid feeding device for a developing machine according to the fourth aspect of the present invention has the above-described configuration, it is difficult to cause a difference in water level for each sub-tank due to a difference in water feeding time caused by a difference in flow path length with a simple configuration. .
（第１実施形態）
次に、本発明の現像機用送液装置の第１実施形態を図１及び図２に従って説明する。
(First embodiment)
Next, a first embodiment of a liquid feeding device for a developing machine according to the present invention will be described with reference to FIGS.
図１に示すように、本実施形態における現像機用送液装置１０は、液体としての純水１２が貯留されるメインタンク１４を備えている。なお、純水１２は、水道水の中に存在する不純物（塩類、残留塩素等）がイオン交換樹脂等によって除去され高純度になっており、給水口１６からメインタンク１４内に供給されるようになっている。 As shown in FIG. 1, the developer feeding device 10 in this embodiment includes a main tank 14 in which pure water 12 as a liquid is stored. The pure water 12 has a high purity because impurities (salts, residual chlorine, etc.) present in the tap water are removed by an ion exchange resin or the like, and is supplied into the main tank 14 from the water supply port 16. It has become.
メインタンク１４の内部には、水位（液面）Ｗ０を検出するための水位検出部材としてのフロートセンサ２０、２２、２４、２６が設けられている。これらのフロートセンサ２０、２２、２４、２６は、メインタンク１４の底部１４Ａからの高さが異なる位置に配置されており、上下方向中間部に配置されたフロートセンサ２２とフロートセンサ２４とで水位Ｗ０を所定範囲内に維持するための検知を行うと共に、上下方向両端部に配置されたフロートセンサ２０とフロートセンサ２６とによって、水位の異常を検知するようになっている。 In the main tank 14, float sensors 20, 22, 24, and 26 are provided as water level detection members for detecting the water level (liquid level) W0. These float sensors 20, 22, 24, and 26 are disposed at different heights from the bottom 14 </ b> A of the main tank 14, and the water level is determined by the float sensor 22 and the float sensor 24 disposed at the middle in the vertical direction. While detecting for maintaining W0 within a predetermined range, the float sensor 20 and the float sensor 26 disposed at both ends in the vertical direction detect an abnormality in the water level.
なお、これらのフロートセンサ２０、２２、２４、２６は、フロート（浮き）を使用した周知の構成であるため、構成の詳細な説明は省略する。また、これらのフロートセンサ２０、２２、２４、２６は、純水１２を供給する制御装置に電気的に接続されており、検知信号を制御装置に出力するようになっている。 Since these float sensors 20, 22, 24, and 26 have a well-known configuration using a float (floating), detailed description of the configuration is omitted. Moreover, these float sensors 20, 22, 24, and 26 are electrically connected to a control device that supplies pure water 12, and output detection signals to the control device.
図２に示すように、メインタンク１４の底部１４Ａに形成した流出口２９には、送液管としての本管３０の一方の端部３０Ａが連結されており、この本管３０は内径Ｒ０の管材によって構成されている。また、本管３０の長手方向中間部３０Ｂにおける最もメインタンク１４に近い位置には、送液管としての第１分岐管３４の一方の端部３４Ａが連結されている。 As shown in FIG. 2, one end 30A of a main pipe 30 serving as a liquid supply pipe is connected to an outlet 29 formed in the bottom 14A of the main tank 14, and the main pipe 30 has an inner diameter R0. It is composed of pipe material. In addition, one end 34A of the first branch pipe 34 as a liquid feeding pipe is connected to a position closest to the main tank 14 in the longitudinal intermediate portion 30B of the main pipe 30.
第１分岐管３４は内径Ｒ１の管材によって構成されており、第１分岐管３４の他方の端部３４Ｂは、第１現像機３６の内部に設けられたサブタンク３８の底部３８Ａに形成された流入口３９に連結されている。また、第１分岐管３４の中間部３４Ｃには開閉バルブ４０が設けられており、開閉バルブ４０を開くことで、メインタンク１４の純水１２が、本管３０と第１分岐管３４とを通って、サブタンク３８の内部に送られるようになっている。 The first branch pipe 34 is made of a pipe material having an inner diameter R1, and the other end 34B of the first branch pipe 34 is a flow formed at the bottom 38A of the sub tank 38 provided inside the first developing device 36. Connected to the inlet 39. In addition, an opening / closing valve 40 is provided in the intermediate portion 34C of the first branch pipe 34, and by opening the opening / closing valve 40, the pure water 12 of the main tank 14 is connected to the main pipe 30 and the first branch pipe 34. It passes through and is sent into the sub tank 38.
メインタンク１４と第１現像機３６のサブタンク３８とは、同じ高さの位置に配置されており、メインタンク１４とサブタンク３８とが本管３０と第１分岐管３４とによって互いに連結されている。このため、開閉バルブ４０を開くことで、メインタンク１４の水位Ｗ０と第１現像機３６のサブタンク３８の水位Ｗ１とがサイフォンの原理によって同一となるようになっている。 The main tank 14 and the sub tank 38 of the first developing device 36 are arranged at the same height, and the main tank 14 and the sub tank 38 are connected to each other by the main pipe 30 and the first branch pipe 34. . Therefore, by opening the on-off valve 40, the water level W0 of the main tank 14 and the water level W1 of the sub tank 38 of the first developing device 36 are made the same by the siphon principle.
本管３０の長手方向中間部３０Ｂにおける第１分岐管３４との連結部からメインタンク１４と反対方向へ所定距離離間した位置には、送液管としての第２分岐管４４の一方の端部４４Ａが連結されている。 One end of a second branch pipe 44 serving as a liquid feed pipe is located at a position spaced apart from the connecting portion with the first branch pipe 34 in the longitudinal intermediate portion 30B of the main pipe 30 in a direction opposite to the main tank 14. 44A is connected.
第２分岐管４４は内径Ｒ２の管材によって構成されており、第２分岐管４４の他方の端部４４Ｂは、第２現像機４６の内部に設けられたサブタンク４８の底部４８Ａに形成された流入口４９に連結されている。また、第２分岐管４４の中間部４４Ｃには開閉バルブ５０が設けられており、開閉バルブ５０を開くことで、メインタンク１４の純水１２が、本管３０と第２分岐管４４とを通って、サブタンク４８の内部に送られるようになっている。 The second branch pipe 44 is made of a pipe material having an inner diameter R2, and the other end 44B of the second branch pipe 44 is a flow formed at the bottom 48A of the sub tank 48 provided inside the second developing device 46. Connected to the inlet 49. In addition, an opening / closing valve 50 is provided in the intermediate portion 44C of the second branch pipe 44, and by opening the opening / closing valve 50, the pure water 12 of the main tank 14 is connected to the main pipe 30 and the second branch pipe 44. It passes through the inside of the sub tank 48.
メインタンク１４と第２現像機４６のサブタンク４８とは、同じ高さの位置に配置されており、メインタンク１４とサブタンク４８とが本管３０と第２分岐管４４とによって互いに連結されている。このため、開閉バルブ５０を開くことで、メインタンク１４の水位Ｗ０と第２現像機４６のサブタンク４８の水位Ｗ２とがサイフォンの原理によって同一となるようになっている。 The main tank 14 and the sub tank 48 of the second developing device 46 are arranged at the same height, and the main tank 14 and the sub tank 48 are connected to each other by the main pipe 30 and the second branch pipe 44. . Therefore, by opening the opening / closing valve 50, the water level W0 of the main tank 14 and the water level W2 of the sub tank 48 of the second developing device 46 are made the same by the siphon principle.
本管３０の長手方向中間部３０Ｂにおける第２分岐管４４との連結部からメインタンク１４と反対方向へ所定距離離間した位置には、送液管としての第３分岐管５４の一方の端部５４Ａが連結されている。 One end of a third branch pipe 54 serving as a liquid feed pipe is located at a position spaced apart from the connecting portion with the second branch pipe 44 in the longitudinal intermediate portion 30B of the main pipe 30 in a direction opposite to the main tank 14. 54A is connected.
第３分岐管５４は内径Ｒ３の管材によって構成されており、第３分岐管５４の他方の端部５４Ｂは、第３現像機５６の内部に設けられたサブタンク５８の底部５８Ａに形成された流入口５９に連結されている。また、第３分岐管５４の中間部５４Ｃには開閉バルブ６０が設けられており、開閉バルブ６０を開くことで、メインタンク１４の純水１２が、本管３０と第３分岐管５４とを通って、サブタンク５８の内部に送られるようになっている。 The third branch pipe 54 is made of a pipe material having an inner diameter R3, and the other end 54B of the third branch pipe 54 is a flow formed at the bottom 58A of the sub tank 58 provided inside the third developing device 56. Connected to the inlet 59. In addition, an opening / closing valve 60 is provided in the intermediate portion 54C of the third branch pipe 54, and by opening the opening / closing valve 60, the pure water 12 of the main tank 14 is connected to the main pipe 30 and the third branch pipe 54. It passes through the inside of the sub tank 58.
メインタンク１４と第３現像機５６のサブタンク５８とは、同じ高さの位置に配置されており、メインタンク１４とサブタンク５８とが本管３０と第３分岐管５４とによって互いに連結されている。このため、開閉バルブ６０を開くことで、メインタンク１４の水位Ｗ０と第３現像機５６のサブタンク５８の水位Ｗ３とがサイフォンの原理によって同一となるようになっている。 The main tank 14 and the sub tank 58 of the third developing device 56 are arranged at the same height, and the main tank 14 and the sub tank 58 are connected to each other by the main pipe 30 and the third branch pipe 54. . Therefore, by opening the opening / closing valve 60, the water level W0 of the main tank 14 and the water level W3 of the sub tank 58 of the third developing device 56 are made the same by the siphon principle.
また、本実施形態では、本管３０の内径Ｒ０、第１分岐管３４の内径Ｒ１、第２分岐管４４の内径Ｒ２及び第３分岐管５４の内径Ｒ３が、Ｒ１＜Ｒ２＜Ｒ３＜Ｒ０となっており、本管３０の流水抵抗Ｔ０、第１分岐管３４の流水抵抗Ｔ１、第２分岐管４４の流水抵抗Ｔ２及び第３分岐管５４の流水抵抗Ｔ３は、Ｔ１＞Ｔ２＞Ｔ３＞Ｔ０となっている。 In the present embodiment, the inner diameter R0 of the main pipe 30, the inner diameter R1 of the first branch pipe 34, the inner diameter R2 of the second branch pipe 44, and the inner diameter R3 of the third branch pipe 54 are R1 <R2 <R3 <R0. The flowing water resistance T0 of the main pipe 30, the flowing water resistance T1 of the first branch pipe 34, the flowing water resistance T2 of the second branch pipe 44, and the flowing water resistance T3 of the third branch pipe 54 are T1> T2> T3> T0. It has become.
従って、管の内径が同じ場合には、メインタンク１４からの流路長が長いために、送水時間が長くなり水位の上昇が遅れるサブタンクに接続される送液管の流水抵抗を、メインタンク１４からの流路長が短いために、送水時間が短くなり水位の上昇が早まるサブタンクに接続される送液管の流水抵抗に比べて小さくすることで、流路長が異なるために生じる送水時間の差による各サブタンク毎の水位差が生じにくくなっている。 Therefore, when the inner diameter of the pipe is the same, since the flow path length from the main tank 14 is long, the flow resistance of the liquid feed pipe connected to the sub tank in which the water feed time is long and the rise in the water level is delayed is set to the main tank 14. Since the flow path length from the pipe is short, the water feed time is shortened and the rise in the water level is shortened. The difference in water level for each sub tank due to the difference is less likely to occur.
具体的には、第１現像機３６のサブタンク３８に比べて、メインタンク１４からの流路長が長い第２現像機４６のサブタンク４８に接続される第２分岐管４４の流水抵抗Ｔ２を、第１現像機３６のサブタンク３８に接続される第１分岐管３４の流水抵抗Ｔ１に比べて小さくすることで、流路長が異なる第１現像機３６のサブタンク３８と、第２現像機４６のサブタンク４８とに水位差が生じにくくなっている。同様に、流路長が異なる第２現像機４６のサブタンク４８と第３現像機５６のサブタンク５８とにも水位差が生じにくくなっている。 Specifically, the flow resistance T2 of the second branch pipe 44 connected to the sub tank 48 of the second developer 46 having a long flow path length from the main tank 14 as compared with the sub tank 38 of the first developer 36, By reducing the flow resistance T1 of the first branch pipe 34 connected to the sub tank 38 of the first developing device 36, the sub tank 38 of the first developing device 36 and the second developing device 46 having different flow path lengths are used. A difference in water level between the sub tank 48 and the sub tank 48 is less likely to occur. Similarly, a water level difference is less likely to occur between the sub tank 48 of the second developing device 46 and the sub tank 58 of the third developing device 56 having different flow path lengths.
なお、図１では、本管３０、第１分岐管３４、第２分岐管４４及び第３分岐管５４を直線状に配管した状態を示しているが、本管３０、第１分岐管３４、第２分岐管４４及び第３分岐管５４は、メインタンク１４、第１現像機３６、第２現像機４６及び第３現像機５６のレイアウトに応じて所定の形状に屈曲して配管されている。 1 shows a state in which the main pipe 30, the first branch pipe 34, the second branch pipe 44, and the third branch pipe 54 are arranged in a straight line, the main pipe 30, the first branch pipe 34, The second branch pipe 44 and the third branch pipe 54 are bent and piped into a predetermined shape according to the layout of the main tank 14, the first developing machine 36, the second developing machine 46, and the third developing machine 56. .
（作用・効果）
本実施形態では、図２に示すように、純水１２が貯留されるメインタンク１４はフロートセンサ２０、２２、２４、２６によって水位Ｗ０を検出することで、水量を管理できる。また、第１現像機３６のサブタンク３８とメインタンク１４とを第１分岐管３４と本管３０とで、第２現像機４６のサブタンク４８とメインタンク１４とを第２分岐管４４と本管３０とで、第３現像機５６のサブタンク５８とメインタンク１４とを第３分岐管５４と本管３０とでそれぞれ連結することで、サイフォンの原理により、ポンプ等を使用することなく、第１現像機３６のサブタンク３８の水位Ｗ１、第２現像機４６のサブタンク４８の水位Ｗ２及び第３現像機５６のサブタンク５８の水位Ｗ３と、メインタンク１４の水位Ｗ０とを同一にできる。
(Action / Effect)
In the present embodiment, as shown in FIG. 2, the main tank 14 in which the pure water 12 is stored can manage the amount of water by detecting the water level W0 using the float sensors 20, 22, 24, and 26. Further, the sub tank 38 and the main tank 14 of the first developing machine 36 are connected to the first branch pipe 34 and the main pipe 30, and the sub tank 48 and the main tank 14 of the second developing machine 46 are connected to the second branch pipe 44 and the main pipe. 30, the sub tank 58 and the main tank 14 of the third developing device 56 are connected by the third branch pipe 54 and the main pipe 30, respectively. The water level W1 of the sub tank 38 of the developing machine 36, the water level W2 of the sub tank 48 of the second developing machine 46, the water level W3 of the sub tank 58 of the third developing machine 56, and the water level W0 of the main tank 14 can be made the same.
従って、フロートセンサ２０、２２、２４、２６によってメインタンク１４の水量を管理することで、同時に、第１現像機３６のサブタンク３８、第２現像機４６のサブタンク４８及び第３現像機５６のサブタンク５８の各水量を管理することができる。この結果、低コストで第１現像機３６、第２現像機４６及び第３現像機５６に純水１２を供給することができる。 Therefore, by managing the amount of water in the main tank 14 by the float sensors 20, 22, 24, 26, the sub tank 38 of the first developing device 36, the sub tank 48 of the second developing device 46, and the sub tank of the third developing device 56 are simultaneously used. Each water amount of 58 can be managed. As a result, the pure water 12 can be supplied to the first developing device 36, the second developing device 46, and the third developing device 56 at low cost.
また、本実施形態では、メインタンク１４に連結された本管３０から分岐された第１分岐管３４が第１現像機３６のサブタンク３８に連結されている。また、本管３０から分岐された第２分岐管４４が第２現像機４６のサブタンク４８に連結されており、本管３０から分岐された第３分岐管５４が第３現像機５６のサブタンク５８に連結されている。従って、メインタンク１４と、第１現像機３６のサブタンク３８、第２現像機４６のサブタンク４８及び第３現像機５６のサブタンク５８とをそれぞれ個別の独立した送液管で連結する場合に比べて、総配管長を短くできコストダウンになる。 In the present embodiment, the first branch pipe 34 branched from the main pipe 30 connected to the main tank 14 is connected to the sub tank 38 of the first developing device 36. A second branch pipe 44 branched from the main pipe 30 is connected to a sub tank 48 of the second developing machine 46, and a third branch pipe 54 branched from the main pipe 30 is connected to a sub tank 58 of the third developing machine 56. It is connected to. Therefore, as compared with the case where the main tank 14 is connected to the sub tank 38 of the first developing device 36, the sub tank 48 of the second developing device 46, and the sub tank 58 of the third developing device 56 by respective independent liquid feeding pipes. The total pipe length can be shortened and the cost is reduced.
また、本実施形態では、本管３０の内径Ｒ０、第１分岐管３４の内径Ｒ１、第２分岐管４４の内径Ｒ２及び第３分岐管５４の内径Ｒ３を、Ｒ１＜Ｒ２＜Ｒ３＜Ｒ０としている。このため、第１現像機３６のサブタンク３８に比べて、メインタンク１４からの流路長が長い第２現像機４６のサブタンク４８に接続される第２分岐管４４の流水抵抗Ｔ２を、第１現像機３６のサブタンク３８に接続される第１分岐管３４の流水抵抗Ｔ１に比べて小さくすることで、第１現像機３６のサブタンク３８と、第２現像機４６のサブタンク４８とに、送水時間の差による水位差を生じにくくできる。同様に、第２現像機４６のサブタンク４８と第３現像機５６のサブタンク５８とにおいても送水時間の差による水位差を生じにくくできる。 In the present embodiment, the inner diameter R0 of the main pipe 30, the inner diameter R1 of the first branch pipe 34, the inner diameter R2 of the second branch pipe 44, and the inner diameter R3 of the third branch pipe 54 are set as R1 <R2 <R3 <R0. Yes. For this reason, the flow resistance T2 of the second branch pipe 44 connected to the sub tank 48 of the second developer 46 having a longer flow path length from the main tank 14 than the sub tank 38 of the first developer 36 is set to the first By reducing the flow resistance T1 of the first branch pipe 34 connected to the sub tank 38 of the developing device 36, the water supply time is reduced to the sub tank 38 of the first developing device 36 and the sub tank 48 of the second developing device 46. The difference in water level due to the difference can be made difficult to occur. Similarly, a difference in water level due to a difference in water supply time can be hardly generated in the sub tank 48 of the second developing device 46 and the sub tank 58 of the third developing device 56.

次に、本発明の現像機用送液装置の第２実施形態を図３に従って説明する。
なお、第１実施形態と同一部材に付いては、同一符号を付してその説明を省略する。
(Second Embodiment)
Next, a second embodiment of the liquid feeder for the developing machine of the present invention will be described with reference to FIG.
In addition, about the same member as 1st Embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.
図３に示すように、本実施形態における現像機用送液装置１０では、メインタンク１４の流出口２９の開口面積Ｓ０、第１現像機３６のサブタンク３８の流入口３９の開口面積Ｓ１、第２現像機４６のサブタンク４８の流入口４９の開口面積Ｓ２及び、第３現像機５６のサブタンク５８の流入口５９の開口面積Ｓ３が、Ｓ１＜Ｓ２＜Ｓ３＜Ｓ０となっている。 As shown in FIG. 3, in the developer feeding device 10 in this embodiment, the opening area S0 of the outlet 29 of the main tank 14, the opening area S1 of the inlet 39 of the subtank 38 of the first developer 36, The opening area S2 of the inlet 49 of the sub-tank 48 of the second developing machine 46 and the opening area S3 of the inlet 59 of the sub-tank 58 of the third developing machine 56 are S1 <S2 <S3 <S0.
なお、本実施形態では、本管３０の内径Ｒ０、第１分岐管３４の内径Ｒ１、第２分岐管４４の内径Ｒ２及び第３分岐管５４の内径Ｒ３は、同一（Ｒ１＝Ｒ２＝Ｒ３＝Ｒ０）としている。 In the present embodiment, the inner diameter R0 of the main pipe 30, the inner diameter R1 of the first branch pipe 34, the inner diameter R2 of the second branch pipe 44, and the inner diameter R3 of the third branch pipe 54 are the same (R1 = R2 = R3 = R0).
従って、流入口の開口面積が同じ場合には、メインタンク１４からの流路長が長いために、送水時間が長くなり水位の上昇が遅れるサブタンクの流入口の流水抵抗を、メインタンク１４からの流路長が短いために、送水時間が短くなり水位の上昇が早まるサブタンクの流入口の流水抵抗に比べて小さくすることで、流路長が異なるために生じる送水時間の差による各サブタンク毎の水位差が生じにくくなっている。 Therefore, when the opening area of the inflow port is the same, the flow path length from the main tank 14 is long, so the water flow resistance at the inflow port of the sub tank where the water supply time is long and the rise in the water level is delayed is from the main tank 14. Since the flow path length is short, the water supply time is shortened and the water level rises faster. Water level difference is less likely to occur.
具体的には、第１現像機３６のサブタンク３８に比べてメインタンク１４からの流路長が長い第２現像機４６のサブタンク４８の流入口４９の流水抵抗Ｔ２を、第１現像機３６のサブタンク３８の流入口３９の流水抵抗Ｔ１に比べて小さくすることで、流路長が異なるために生じる送水時間の差による第１現像機３６のサブタンク３８と第２現像機４６のサブタンク４８との水位差が生じにくくなっている。同様に、第２現像機４６のサブタンク４８と第３現像機５６のサブタンク５８とにおいても水位差を生じにくくなっている。 Specifically, the flow resistance T2 of the inlet 49 of the sub tank 48 of the second developer 46 having a longer flow path length from the main tank 14 than the sub tank 38 of the first developer 36 is set to By making it smaller than the flow resistance T1 of the inlet 39 of the subtank 38, the subtank 38 of the first developing machine 36 and the subtank 48 of the second developing machine 46 due to the difference in water feeding time caused by the different flow path lengths. Water level difference is less likely to occur. Similarly, a difference in water level is less likely to occur between the sub tank 48 of the second developing device 46 and the sub tank 58 of the third developing device 56.
（作用・効果）
本実施形態では、第１実施形態と同様に、低コストで第１現像機３６、第２現像機４６及び第３現像機５６に純水１２を供給できると共に総配管長を短くできる。また、メインタンク１４の流出口２９の開口面積Ｓ０、第１現像機３６のサブタンク３８の流入口３９の開口面積Ｓ１、第２現像機４６のサブタンク４８の流入口４９の開口面積Ｓ２及び、第３現像機５６のサブタンク５８の流入口５９の開口面積Ｓ３が、Ｓ１＜Ｓ２＜Ｓ３＜Ｓ０となっている。このため、第１現像機３６のサブタンク３８に比べて流路長が長い第２現像機４６のサブタンク４８の流入口４９の流水抵抗Ｔ２を、第１現像機３６のサブタンク３８の流入口３９の流水抵抗Ｔ１に比べて小さくすることで、流路長が異なるために生じる送水時間の差による第１現像機３６のサブタンク３８と第２現像機４６のサブタンク４８の水位差を生じにくくできる。同様に、第２現像機４６のサブタンク４８と第３現像機５６のサブタンク５８とにおいても水位差を生じにくくできる。
(Action / Effect)
In the present embodiment, as in the first embodiment, the pure water 12 can be supplied to the first developing device 36, the second developing device 46, and the third developing device 56 at a low cost, and the total pipe length can be shortened. Further, the opening area S0 of the outlet 29 of the main tank 14, the opening area S1 of the inlet 39 of the sub tank 38 of the first developing machine 36, the opening area S2 of the inlet 49 of the sub tank 48 of the second developing machine 46, and the first The opening area S3 of the inlet 59 of the sub-tank 58 of the three developing machine 56 is S1 <S2 <S3 <S0. For this reason, the flow resistance T2 of the inlet 49 of the subtank 48 of the second developer 46 having a longer flow path length than the subtank 38 of the first developer 36 is set to the inlet 39 of the subtank 38 of the first developer 36. By making it smaller than the flowing water resistance T1, the difference in water level between the sub-tank 38 of the first developing device 36 and the sub-tank 48 of the second developing device 46 due to the difference in water feeding time caused by the different flow path lengths can be made difficult to occur. Similarly, a difference in water level can be hardly generated in the sub tank 48 of the second developing device 46 and the sub tank 58 of the third developing device 56.
（第３実施形態）
次に、本発明の現像機用送液装置の第３実施形態を図４に従って説明する。
なお、第１実施形態と同一部材に付いては、同一符号を付してその説明を省略する。
(Third embodiment)
Next, a third embodiment of the liquid feeder for the developing machine according to the present invention will be described with reference to FIG.
In addition, about the same member as 1st Embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.
図４に示すように、本実施形態における現像機用送液装置１０では、メインタンク１４と第１現像機３６のサブタンク３８とが、第１送液管７０によって直接連結されている。また、メインタンク１４と第２現像機４６のサブタンク４８とが、第２送液管７２によって直接連結されており、メインタンク１４と第３現像機５６のサブタンク５８とが、第３送液管７４によって直接連結されている。なお、第１送液管７０の中間部には開閉バルブ７６が設けられており、開閉バルブ７６を開くことで、メインタンク１４の純水１２が、第１送液管７０を通って、サブタンク３８の内部に送られるようになっている。同様に、第２送液管７２の中間部には開閉バルブ７８が設けられており、第３送液管７４の中間部には開閉バルブ８０が設けられている。 As shown in FIG. 4, in the developing device liquid feeding apparatus 10 in the present embodiment, the main tank 14 and the sub tank 38 of the first developing device 36 are directly connected by a first liquid feeding pipe 70. The main tank 14 and the sub tank 48 of the second developing device 46 are directly connected by the second liquid feeding pipe 72, and the main tank 14 and the sub tank 58 of the third developing machine 56 are connected to the third liquid feeding pipe. 74 is directly connected. An opening / closing valve 76 is provided in the middle portion of the first liquid feeding pipe 70, and by opening the opening / closing valve 76, the pure water 12 in the main tank 14 passes through the first liquid feeding pipe 70 and enters the sub tank. 38 is sent inside. Similarly, an opening / closing valve 78 is provided in the middle part of the second liquid feeding pipe 72, and an opening / closing valve 80 is provided in the middle part of the third liquid feeding pipe 74.
また、第１送液管７０の内径Ｒ４（図示省略）、第２送液管７２の内径Ｒ５（図示省略）及び第３送液管７４の内径Ｒ６（図示省略）は、Ｒ４＜Ｒ５＜Ｒ６となっており、第１送液管７０の流水抵抗Ｔ４、第２送液管７２の流水抵抗Ｔ５及び第３送液管７４の流水抵抗Ｔ６は、Ｔ４＞Ｔ５＞Ｔ６となっている。 The inner diameter R4 (not shown) of the first liquid feeding pipe 70, the inner diameter R5 (not shown) of the second liquid feeding pipe 72, and the inner diameter R6 (not shown) of the third liquid feeding pipe 74 are R4 <R5 <R6. The flow resistance T4 of the first liquid supply pipe 70, the flow resistance T5 of the second liquid supply pipe 72, and the flow resistance T6 of the third liquid supply pipe 74 satisfy T4> T5> T6.
従って、管の内径が同じ場合には、メインタンク１４からの流路長が長いために、送水時間が長くなり水位の上昇が遅れるサブタンクに接続される送液管の流水抵抗を、メインタンク１４からの流路長が短いために、送水時間が短くなり水位の上昇が早まるサブタンクに接続される送液管の流水抵抗に比べて小さくすることで、流路長が異なるために生じる送水時間の差による各サブタンク毎の水位差が生じにくくなっている。 Therefore, when the inner diameter of the pipe is the same, since the flow path length from the main tank 14 is long, the flow resistance of the liquid feed pipe connected to the sub tank in which the water feed time is long and the rise in the water level is delayed is set to the main tank 14. Since the flow path length from the pipe is short, the water feed time is shortened and the rise in the water level is shortened. The difference in water level for each sub tank due to the difference is less likely to occur.
具体的には、第１現像機３６のサブタンク３８に比べてメインタンク１４からの流路長が長い第２現像機４６のサブタンク４８に接続される第２送液管７２の流水抵抗Ｔ５を、第１現像機３６のサブタンク３８に接続される第１送液管７０の流水抵抗Ｔ４に比べて小さくすることで、流路長が異なるために生じる送水時間の差による第１現像機３６のサブタンク３８と第２現像機４６のサブタンク４８との水位差が生じにくくなっている。同様に、第２現像機４６のサブタンク４８と第３現像機５６のサブタンク５８とにおいても水位差を生じにくくなっている。 Specifically, the flowing water resistance T5 of the second liquid feeding pipe 72 connected to the sub tank 48 of the second developer 46 having a long flow path length from the main tank 14 as compared with the sub tank 38 of the first developer 36, By reducing the flow resistance T4 of the first liquid feeding pipe 70 connected to the sub tank 38 of the first developing device 36, the sub tank of the first developing device 36 is caused by the difference in the water feeding time caused by the different flow path lengths. 38 and the sub tank 48 of the second developing device 46 are less likely to cause a difference in water level. Similarly, a difference in water level is less likely to occur between the sub tank 48 of the second developing device 46 and the sub tank 58 of the third developing device 56.
なお、図４では、第１送液管７０、第２送液管７２及び第３送液管７４をＬ字状に配管した状態を示しているが、第１送液管７０、第２送液管７２及び第３送液管７４は、メインタンク１４、第１現像機３６、第２現像機４６、第３現像機５６のレイアウトに応じて所定の形状に屈曲して配管されている。 4 shows a state in which the first liquid feeding pipe 70, the second liquid feeding pipe 72, and the third liquid feeding pipe 74 are arranged in an L shape, the first liquid feeding pipe 70, the second liquid feeding pipe 74, and the second liquid feeding pipe 74 are shown. The liquid pipe 72 and the third liquid feeding pipe 74 are bent and piped into a predetermined shape according to the layout of the main tank 14, the first developing machine 36, the second developing machine 46, and the third developing machine 56.
（作用・効果）
本実施形態では、第１現像機３６のサブタンク３８とメインタンク１４とを第１送液管７０とで、第２現像機４６のサブタンク４８とメインタンク１４とを第２送液管７２とで、第３現像機５６のサブタンク５８とメインタンク１４とを第３送液管７４とでそれぞれ連結することで、サイフォンの原理により、ポンプ等を使用することなく、第１現像機３６のサブタンク３８の水位、第２現像機４６のサブタンク４８の水位及び第３現像機５６のサブタンク５８の水位と、メインタンク１４の水位とを同一にできる。
(Action / Effect)
In this embodiment, the sub tank 38 and the main tank 14 of the first developing machine 36 are connected by the first liquid feeding pipe 70, and the sub tank 48 and the main tank 14 of the second developing machine 46 are connected by the second liquid feeding pipe 72. By connecting the sub tank 58 of the third developing device 56 and the main tank 14 with the third liquid feeding pipe 74, respectively, the sub tank 38 of the first developing device 36 is used without using a pump or the like according to the principle of siphon. , The water level of the sub tank 48 of the second developing device 46, the water level of the sub tank 58 of the third developing device 56, and the water level of the main tank 14 can be made the same.
従って、フロートセンサ２０、２２、２４、２６によってメインタンク１４の水量を管理することで、同時に、第１現像機３６のサブタンク３８、第２現像機４６のサブタンク４８及び第３現像機５６のサブタンク５８の各水量を管理することができる。この結果、低コストで第１現像機３６、第２現像機４６及び第３現像機５６に純水を供給することが可能になる。 Therefore, by managing the amount of water in the main tank 14 by the float sensors 20, 22, 24, 26, the sub tank 38 of the first developing device 36, the sub tank 48 of the second developing device 46, and the sub tank of the third developing device 56 are simultaneously used. Each water amount of 58 can be managed. As a result, it is possible to supply pure water to the first developing device 36, the second developing device 46, and the third developing device 56 at a low cost.
また、本実施形態では、第１現像機３６のサブタンク３８に比べてメインタンク１４からの流路長が長い第２現像機４６のサブタンク４８に接続される第２送液管７２の流水抵抗Ｔ５を、第１現像機３６のサブタンク３８に接続される第１送液管７０の流水抵抗Ｔ４に比べて小さくすることで、流路長が異なるために生じる送水時間の差による第１現像機３６のサブタンク３８と第２現像機４６のサブタンク４８との水位差を生じにくくできる。同様に、第２現像機４６のサブタンク４８と第３現像機５６のサブタンク５８とにおいても水位差を生じにくくできる。 In the present embodiment, the flow resistance T5 of the second liquid feeding pipe 72 connected to the sub tank 48 of the second developing device 46 having a longer flow path length from the main tank 14 than the sub tank 38 of the first developing device 36. Is made smaller than the flowing water resistance T4 of the first liquid feeding pipe 70 connected to the sub tank 38 of the first developing machine 36, so that the first developing machine 36 due to the difference in water feeding time caused by the different flow path lengths. The difference in water level between the sub tank 38 and the sub tank 48 of the second developing device 46 can be made difficult to occur. Similarly, a difference in water level can be hardly generated in the sub tank 48 of the second developing device 46 and the sub tank 58 of the third developing device 56.
