Description

【０００１】
【発明が属する技術分野】
この発明は、水道メータ部品等の対象物を収容し、所定の液中に浸漬するための浸漬収容ケースに関する。
【０００２】
【従来の技術】
水道メータは一般に本体ハウジングとなるような下ケースと、これに組み合わされる上ケース（上蓋）とを備えるのが普通で、水が主に流通するその下ケースの材質に鉛を含む合金が採用される場合がある。その場合、水中に鉛が溶出すること防止するために、その下ケースを所定の液に浸漬してその液を下ケースの表面に接触させる液処理（ドブ付けメッキのような処理）を行うことがある。
【０００３】
そのような浸漬処理に際しては、水道メータ部品である下ケースを輸送用のコンテナに収納して、目的とする専用の液処理工場等へ搬入し、浸漬工程の際には多数の下ケースを輸送用コンテナから取り出し、浸漬用バスケットに多数投入し、そのバスケットを介して所定の液中に浸漬し、それが終わると、浸漬用バスケットから液処理後の下ケースを取り出し、再び輸送用のコンテナに収容して所定の場所へ運んでいた。
【０００４】
【発明が解決しようとする課題】
しかしながら、このような輸送用コンテナから浸漬用バスケットへの移転、液処理後の浸漬用バスケットから輸送用コンテナへの積み替えは、多くの労力と時間・コストを要し、生産性を高める上での障害となる。
【０００５】
この発明は、浸漬工程から輸送・保管まで一貫して使用できる浸漬収容ケースを提供することを課題とする。
【０００６】
【課題を解決するための手段及び発明の効果】
この発明は、両側に突き出し部を有する水道メータ部品等の対象物を位置を規定して収容し、保管・輸送及び所定の液への浸漬処理を行うための収容ケースであって、
全体が耐液性を有するとともに、少なくとも底部が通液性を備え、その底部に前記対象物を保持する保持部が固定又は一体に形成され、該ケースの底部が前記対象物の重量を支持すべく該対象物を着座させるとともに、前記保持部はその対象物の両側の突き出し部を浮かせた状態で受け入れるために、前記突き出し部の下端より低い位置に底部が形成された凹部を有して、両者間に所定の隙間が形成されるようにし、かつ前記突き出し部と該凹部の前後端との間にも所定の隙間が確保されるように凹部の間口幅が形成され、前記隙間は当該ケースを前記液中で揺動させることにより前記対象物を前記凹部の範囲内で前記保持部に対して相対的に移動させる隙間とされたことを特徴とする。
【０００７】
これにより、該浸漬収容ケースの保持部に水道メータ部品等の対象物を保持した状態で、所定の液中にこの浸漬収容ケースごと浸漬され、その液中で該ケースが揺動させられると、対象物の両側の突き出し部と凹部との隙間の範囲でその対象物が保持部に対して相対的に移動し、対象物の表面にくまなく液を接触させやすくなる。
【０００８】
通常では対象物をいかにガタ無く固定し、保持するかが重要と考えられるが、これとは逆に、積極的に対象物を移動（揺動等）させるに必要な隙間（凹部）を形成することにより、浸漬工程で対象物の一部（例えば支持されている箇所）に液が触れなかったり、空洞部に空気が残り、そこに液が回らなかったりすることを可及的に防ぐことができる。
【０００９】
また、従来の浸漬用バスケットに対象物をバラで投入して浸漬する場合は、対象物に傷が付きやすいのに対し、この浸漬収容ケースを使用すれば、対象物の移動が適度に規制され、対象物同士の衝突が回避されるから、対象物に傷が付きにくい効果もある。
【００１０】
しかも、浸漬工程のみならず、運搬や保管にもこのケースを使用できるから、運搬してきた当該ケースをそのまま液中に浸漬し、その後、当該ケースに入れたままで対象物を輸送することができるから、浸漬工程が改善されるのみならず、工程間あるいは工場間の輸送の効率が飛躍的に向上する。
【００１１】
また、本発明では、対象物をケース底部で支持し、かつ対象物の両側の突き出し部を保持部の凹部により浮かせた状態で受け入れることにより、対象物の位置がその凹部で規定され、かつその凹部内で対象物の保持部に対する移動が許容されるとともに、対象物の両側の突き出し部が凹部の下端等に触れないから、浸漬の際にその突き出し部の外周に十分に液が付着し、またケースの揺動を介して、ケース底部に対し対象物が移動（揺動や滑動等）することにより、対象物の上記ケース底部で支持される部分にも液が回り、良好な液処理ができる。
【００１２】
【発明の実施の形態】
以下、この発明の実施の形態を図面に示す実施例を参照しつつ説明する。
図１及び図２に示す浸漬収容ケース１は、方形のケース本体２と、その内側に形成された保持部３とを有し、その保持部３はケース本体２の側部と平行に延びる保持板４を２条以上（この例では１０条）備え、各保持板４はこれと直交する補強板５により補強されている。より詳しくは、ケース本体２の短辺側の側部２ａと平行に１０個の保持板４がケース本体２の内部に設けられ、ケース本体２の長辺側の側部２ａと平行に２個の補強板５が設けられている。この例では、本体ケース２と保持部３とは別体に形成され、本体ケース２に保持板４及び補強板５が組み込まれた形態となっていて、ケース本体２はポリプロピレン等の樹脂で形成され、保持板４及び補強板５は硬質ウレタン等の樹脂で形成されて、いずれも浸漬される液に対する耐液性を有している。
【００１３】
各保持板４には後述する対象物としての水道メータ下ケース（水道メータ部品）の突き出し部を受け入れる凹部６が所定の間隔で複数形成されて、互いに対応する１組の凹部６に水道メータ部品の両側の突き出し部が予め定められた隙間を介して入り込み、保持板４と平行な方向の揺動によりその部品が保持板４に対して同じ方向に揺動可能とされている。
【００１４】
具体的には、図３（ａ）に示すように、保持板４は長手方向に所定の間隔で複数（この例では４個）の凹部６を備え、また上記補強板５との組立のために２個の切り込み７を有している。また各凹部６は、上側がやや開くようなテーパ状に形成され、この保持板４をトムソン刃等で打ち抜いた際の、製品の取り出しが容易にされるとともに、水道メータ部品の突き出し部を凹部６に挿入しやすくなっている。
【００１５】
また、同図（ｂ）に示すように、補強板５は長手方向に複数の切り込み８を備え、この切り込み８は１０枚の保持板４と交差状態で組み合わせるために、１０箇所に形成されている。補強板５の切り込み８と保持板４の切り込み７とが互いに差し込まれて互いに同じ高さＨとなり、各保持板４の上端と各補強板５の上端（低い切欠１１の底部）とがほぼ面一になるような格子構造となる。また各補強板５の下側縁には複数（５個）の切欠９が所定の切り込み８の間に形成されており、これらの切欠９が当該ケース１が液中に浸漬された際にその液を流通させる液流通部（液通路）となる。これにより補強板５でケース内部が仕切られいても、補強板５と交差する（直交する）方向における液の流動がスムーズに行われる。なお、補強板５の両端部には側方に突出する突起１０がそれぞれ形成されており、これらの突起１０が図１に示すケース本体２の側部２ａにおける網目構造の網孔２ｃに嵌り込むことにより、補強板５ひいては保持板４がケース本体４に固定されている。
【００１６】
図７〜図１０は、ケースへ収容される水道メータ部品としての下ケース（この例では口径１３mmのもの）１３を示している。この下ケース１３は円筒容器状をなし、上部の開口１３ａと、両側に突き出た突き出し部としての袖部１３ｅ、１３ｆ（管部）と、これら袖部１３ｅ、１３ｆの開口である水の流出入口１３ｂ、１３ｃとを備える。流出入口１３ｂ、１３ｃの一方から他方へ流れる水が、内部にピボット軸３６（図９（ｂ）参照）を介して回転自在に保持された羽根車を回転させ、この回転数に基づいて水の流量（使用量）が検出される。上記羽根車を回転自在に支持するピボット軸３６は、この下ケースの底部に立設され、そのピボット軸３６の頂点に羽根車が緩く嵌って支持されるが、そのピボット軸の下端部は図９に示されるねじ穴１３ｇ（有底・非貫通）にねじ込まれて固定される。このような水道メータは通常、単箱式水道メータと称される。
【００１７】
上記のような水道メータ部品としての下ケース１３は、図４及び図５に示すように、その開口１３ａを横に向けるようにしてこの浸漬収容ケース２の底部２ｂで支持されるとともに、互いに所定間隔（下ケース１３の袖部間の外寸法より狭い間隔）で配置された２枚の保持板４に形成された、互いに対応する各凹部６に、下ケース１３の袖部１３ｅ、１３ｆが浮き上がった状態で入り込む。言い換えれば、各袖部１３ｅ、１３ｆの下端より、凹部６の下端部（底部）の方が一定量低くされ、そのため各袖部１３ｅ、１３ｆの下端と凹部６の底部との間には一定の隙間ができる。また各凹部６の内側の前後端と、各袖部１３ｅ、１３ｆの外面との間にも一定の隙間が確保されるように、凹部６の間口幅が定められている。
【００１８】
図６は、水道メータ部品である上記下ケース１３と保持板４の凹部６との関係を模式的に示すものである。この図からも明らかなように、下ケース１３を浸漬収容ケース１に収容した状態で、下ケース１３の袖部１３ｅ、１３ｆと凹部４との間に、上下の隙間ｔ1、側方の隙間ｔ2が設定され、下ケース１３の下部がケース底部２ｂ上に着座した状態となる。図１１は図１の浸漬収容ケース１を規定数の下ケース１３で満たした状態（この例では２０個）を示してしる。
【００１９】
そして、複数の浸漬収容ケース１が所定の枠ケージ（パンチングメタル等で構成される集合ケージ等）に格納された状態で、所定の液（例えば鉛溶出防止処理液）にその枠ケージごと浸漬される。より詳しくは、脱脂液槽、水洗槽、表面調整槽、水洗槽、化成処理槽、水洗槽、湯洗槽等に対し、クレーン等で枠ケージが吊り下げられ、それに支持された浸漬収容ケースがその枠ベースとともに各槽に順次浸漬されることとなる。
【００２０】
その浸漬の際に、例えばクレーン等の支持手段により枠ゲージが一定の方法へ揺動させられ、それにより各浸漬収容ケース１内の水道メータ部品である下ケース１３は、図６（ｃ）に概念を示すように、開口１３ａをほぼ横方向に向けた状態で、保持板４と平行な面を基準としてケース本体底部２ｂに対して移動（揺動やスライド等）する。その結果、収容部品たる下ケース１３は、外面側では液の相対的な流動が大きく、内面側ではそれとともに空気が閉じこめられにくく、よって外面側でも内面側でも、処理液等の液にまんべんなく触れやすくなり、液処理の欠落部が生じにくい良好な液処理が実施される。特にこの例で、図９に示す下ケース１３の底部に形成されたピボット軸３６の固定用ねじ穴１３ｇを横方向に寝かせた状態で、そのねじ穴１３ｇが上下に小角度揺動することで、そのねじ穴１３ｇ内に空気が閉じ込められること（エアポケットの発生）を回避することができる。
【００２１】
次に、浸漬収容ケースの別の実施例を図１２ないし図１８に基づいて説明する。
この例の浸漬収容ケース２１は、図１２ないし図１４等に示されるように、ケース本体２２（これは前記ケース本体２と同じもの）と、その内部に形成された保持部２３とを備え、保持部２３はケース本体２２の長辺方向の２つの側部２２ａに沿った２枚の保持板２４ａ、２４ａと、それらと平行にかつそれらの中間において中央を横断する保持板２４ｂと、ケース本体２２の短辺方向の２つの側部２２ａに沿って配置された２枚の補強板２５ａ、２５ａと、各保持板２４ａの中間に配された短い補強板２５ｂ、２５ｂとを備えている。
【００２２】
各保持板２４ａは、図１５にも示すように、後述する対象物としての水道メータ部品を保持するための複数（５個）の凹部２６を、上部に所定の間隔で備え、また下部には液の流通を許容する複数（５個）の切欠３１を隣り合う凹部２６の中間位置に有している。また、保持板２４ａは、両端部に下向きの切り込み２８と、側方に突出する突起３０を備え、各突起３０がケース本体２２の側部の網孔に嵌め込まれてケース本体２２に固定される。この点は図１と同様である。また保持板２４ａの上記切り込み２８に対し、図１２等に示す補強板２５ａの下向きの切り込み（図示せず）が差し込まれて、両者が直交するように組み合わされる。
【００２３】
中央の保持板２４ｂについて、その両端部に形成された突起（図１５の突起３０と同様のもの）においてケース本体２２に固定される構造、及び両端部に形成された上向きの切り込みに補強板２５ａの下向きの切り込みが差し込まれる構造は、両サイドの保持板２４ａと同様であるが、水道メータ部品の後述する袖部を受け入れる凹部の形態は相違している。中央の保持板２４ｂの長手方向には、図１２、１３に示すように、上向きに複数の凸部２７が一定の間隔で形成され、これら凸部２７の間の部分が一定間隔の複数の凹部２８となっていて、中央の保持板２４ｂの凹部２８の個数は、両サイドの保持板２４ａにおける凹部２６の数（この例では５個）の２倍（１０個）となっている。
【００２４】
つまり、中央の保持板２４ｂは両サイドの各保持板２４ａに共通に対向する保持板とされる。中央の保持板２４ｂには、両サイドにおける一方の保持板２４ａに形成された凹部２６と対応する凹部２８と、他方の保持板２４ａに形成された凹部２６と対応する凹部２８とが交互に（一つおきに）形成されていることとなり、両サイドの保持板２４ａ、２４ａの各凹部２６の形成位置は所定のピッチ（この例では半ピッチ）互いにずれている。この例でも、保持板２４ａ、２４ｂ及び補強板２５ａ、２５ｂは硬質ポリウレタン等の樹脂で形成され、ポリプロピレン等の樹脂からケース本体２２とともに、浸漬される液に対する耐液性を有している。
【００２５】
上記のような浸漬収容ケース２１に収容する対象物の水道メータ部品の一例が、図１９及び図２０に示されている。これは水道メータのハウジングを構成する下ケース３３であり、その上部の開口３３ａに対し上ケースが組み付けられる。その中央部の両側から側方へ突き出した突き出し部として袖部３３ｅ、３３ｆを（管部）を備え、その各端部が水の流出入口３３ｂ、３３ｃとされ（この例はこの開口直径（口径）が例えば２０mm）、この場合は３３ｃを流入口、３３ｂを流出口として水が流通し、その水の流れにより回転する羽根車の回転数に基づき流量（水道使用量）が計量される。このような水道メータは通常、複箱式水道メータと称される。
【００２６】
この下ケース３３は内部に計量室ケース等を組み込みための内フランジ３３ｈ（図１９（ｂ）参照）が形成されていて、所定の液に浸漬したとき、この内フランジ３３ｈのために、開口３３ａからケース底部側へ液が回り入り込みにくい構造となっている。このような場合は、流出入口３３ｂ、３３ｃの軸線と平行な面を基準に下ケース３３を揺動させると、その内部へ処理液が回りやすいと言える。つまり、図７等に示した前述の下ケース１３は流出入口１３ｂ、１３ｃの軸線と直角な面を基準に下ケース１３を揺動させることを前提にしていたが、図１９等に示す下ケース３３ではこれと揺動の向きが９０度異なるということができる。
【００２７】
図１６、図１７は上記のような下ケース３３を１個だけ浸漬収容ケース２１に入れた状態を示しており、図２１はその浸漬収容ケース２１を規定数（この場合は１０個）の下ケース３３で満たした状態を示している。また図１８はその水道メータ部品である下ケース３３の、浸漬収容ケース２１に対する収容状態を模式的に示すものである。この図からも明らかなように、下ケース３３は開口３３ａが下で底部が上になるように伏せられた状態で、保持板２４ａと２４ｂとの間にセットされる。
【００２８】
より詳しくは、開口３３ａの端面がケース本体２２の底部に着座してここで重量が支持され、また両側に突き出した袖部３３ｅ、３３ｆが、サイドの保持板２４ａの凹部２６と、センターの保持板２４ｂの凹部２７とに、高さ方向（上下）の隙間ｓ1と横方向（前後）の隙間ｓ２を介して、いわば浮き上がった状態で入り込む（受け入れられる）。言い換えれば、各凹部２６及び２７の底部（底面）は、袖部３３ｅ及び３３ｆの下端より低く形成されており、また各袖部３３ｅ、３３ｆは根元側がより太くなるテーパ状の形態をなしているが、各凹部２６、２８の幅（間口）はそのテーパ状の外形より一定の隙間分広く形成されているため、下ケース３３は各保持板２４ａ、２４ｂに対して袖部３３ｅ、３３ｆの軸方向に所定の小距離分移動することができる。
【００２９】
そして、このようして複数の下ケース３３を収容した浸漬収容ケース２１を、前述のような枠ゲージに入れて、前述と同様にして処理液中に浸漬し、図１２等における保持板２４ａと２４ｂとの対向方向に揺動させると、図１８（ｃ）に示すように、下ケース３３はケース本体２２とともに揺動しつつ、ケース本体２２の底部上を滑るように往復動し、これにより下ケース３３のケース本体２２に対する着座部にも十分処理液が接触し、また下ケース３３の内部にも、図１９（ｂ）の内フランジ３３ｈの存在にかかわらず、その奥部まで液が回り込みやすくなる。
そのため、上ケース３３の外側にも内側にも十分に液が接触し、液欠落部の生じにくい良好な液処理が可能となる。
【００３０】
さらに別の実施例として、図２２には、収容対象物として図７等の両側の袖部１３ｅ、１３ｆがさらに長く延びた下ケース４３（例えば口径１３mmのロングタイプ）を所定個数、例えば１２個収容する浸漬収容ケース４１を示している。このケース本体２は前述の実施例と同じものであり、また内部の保持部は、図１及び図２等と比較すると、異なる点は保持板４間のスパンが長くなった分、その保持板４の数が１０枚から６枚に減らされている点であり、その他の部分は前述の実施例と同様であって、図１等に示した浸漬収容ケース１と実質的に同様の作用効果が得られる。
【００３１】
図２３に示すさらに別の実施例は、収容対象物として図１９等に示す上ケース３３の口径が拡大、及び全体的に大きくされて通水可能量が増えた下ケース５３（例えば口径２５mmロング）を所定個数、例えば８個収容する浸漬収容ケース５１を示している。このケース本体２は前述の実施例と同じものであり、また内部の保持部は、図１２及び図１３等と比較すると、異なる点は保持板２４ａの凹部２６の数を５個から４個に減らした保持板３４ａと、保持板２４ｂの凹部２８の数を１０個から８個に減らした保持板３４ｂを使用している点であり、補強板３５ａ、３５ｂは前述の補強板２５ａ、２５ｂと同様であって、この例でも図１２等に示したものと実質的に同様の作用効果が得られる。
【００３２】
なお、以上のような浸漬収容ケース１、２１、４１、５１は、内部の保持部に関しては収容対象である水道メータ部品のサイズや形状に応じて変更されるが、ケース本体２、２２はすべてを通じて共通である。そして、所定の液槽への浸漬に際しては、先にも述べたように、図２４に概念的に示すような枠ゲージ６０（例えばパンチングメタル等の通通液性がある複数の棚が形成されたもの）の各棚に、所定の水道メータ部品（下ケース１３、３３、４３、５３等）を収容した浸漬収容ケース（この例ではＮｏ．１〜Ｎｏ．１５）を格納し、枠ゲージ６０をクレーン等の吊り下げ手段で液槽に浸漬した状態で、上記枠ゲージ６０をその吊り下げ手段又は専用の揺動手段により一方向、例えば浸漬収容ケースの短辺方向に沿うように揺動させると、前述のように対象物に対する液の回りがよくなる。
【００３３】
ここで、図２４のＮｏ．１〜Ｎｏ．１５のケースは、すべて同じ種類のもの（例えば浸漬収容ケース１のみを複数）としてもよいし、異なる種類（例えば浸漬収容ケース１、２１、４１、５１）の任意の組合せとしてもよい。例えば浸漬収容ケース１と２１を混合して枠ケージに入れて液槽に浸漬し、その状態で一方向に（複数方向でもよいが）揺動させれば、前述した図６（ｃ）に示すような下ケース１３の保持板４と平行な方向に沿った揺動と、図１８（ｃ）に示したような下ケース３３の保持板２４ａと直角な方向に沿った揺動とが同時に生じる。言い換えれば、図６の下ケース１３では袖部１３ｅ、１３ｆの軸方向と直角な方向に沿った揺動、図１８の下ケース３３では袖部３３ｅ、３３ｆの軸方向と平行な方向に沿った揺動が生じ、各上ケース１３、３３の形態・構造に応じて液の回りを良好にすることができる。
【００３４】
以上は主に、所定の液槽へ浸漬する点に着目して各浸漬収容ケースを説明したが、上記のような浸漬収容ケースは、水道メータ部品等の対象物を保管したり、運搬（輸送）したりする際にもそのまま使用することができる。その際、上記した浸漬収容ケース１、２１、４１、５１においてケース本体の少なくとも平面サイズは共通である。そして、図２５に示すように、ケース本体の底部には、積み重ね時の嵌合部７０が下向きに突出して、かつ底面視で方形に又は４個のコーナー部のみに部分的に設けられ、積み重ね状態でそのケース底部の嵌合部７１が、ケース開口部１７の内側に嵌合して位置決めされる。
【００３５】
したがって、前記水道メータ部品等の対象物を収容した複数のケース１等を、上記のように積み重ねた状態で保管したり、トラック等に載せて運搬したりすることができ、かつそのケース１等は所定の液に対し、耐液性と通液性を有するから、ケース１等に収容した対象物を取り出すことなく、そのまま前記枠ゲージ等を介して、又は積み重ね状態のままで、前述の液槽に対する浸漬を実施することができ、逆に浸漬後の対象物をケース１等に収容したまま、保管や運搬ができるから、作業効率が大幅に向上する。
【００３６】
以上の説明では、浸漬収容ケースにおいてケース本体２，２２と保持部３，２３とが別体で形成され、両者が組立により一体化された例を説明したが、ケース本体と保持部（補強部も含めて）が一体に形成されてもよい。例えば樹脂による一体成形も可能である。

[Technical field to which the invention belongs]
The present invention relates to an immersion housing case for housing an object such as a water meter part and soaking it in a predetermined liquid.
[0002]
[Prior art]
A water meter generally has a lower case that serves as a main body housing and an upper case (upper lid) combined therewith, and an alloy containing lead is adopted as the material of the lower case through which water mainly circulates. There is a case. In that case, in order to prevent lead from eluting in the water, a liquid treatment (treatment such as plating with plating) is performed by immersing the lower case in a predetermined liquid and bringing the liquid into contact with the surface of the lower case. There is.
[0003]
In such immersion treatment, the lower case, which is a water meter component, is stored in a container for transportation and carried into a special liquid treatment plant, etc., where many lower cases are transported during the immersion process. Take out from the container for use, put in a large number of baskets for immersion, and immerse in the prescribed liquid through the basket. After that, remove the lower case after the liquid treatment from the basket for immersion, and again into the container for transportation. Contained and carried to the designated place.
[0004]
[Problems to be solved by the invention]
However, such a transfer from a transport container to a soaking basket and a transshipment from a soaking basket to a transporting container after liquid treatment require a lot of labor, time and cost, and increase productivity. It becomes an obstacle.
[0005]
This invention makes it a subject to provide the immersion storage case which can be used consistently from an immersion process to transportation and storage.
[0006]
[Means for Solving the Problems and Effects of the Invention]
The present invention is a storage case for storing a target such as a water meter part having protrusions on both sides, specifying the position, and storing / transporting and immersing in a predetermined liquid,
The whole has liquid resistance, and at least the bottom has liquid permeability, and a holding portion for holding the object is fixed or integrally formed on the bottom, and the bottom of the case supports the weight of the object. In order to seat the object as much as possible, the holding part has a recess with a bottom formed at a position lower than the lower end of the protruding part in order to receive the protruding parts on both sides of the object in a floating state. A gap width is formed in the recess so that a predetermined gap is formed between the two and a predetermined gap is secured between the protruding portion and the front and rear ends of the recess. By swinging in the liquid, the object is made a gap that moves relative to the holding portion within the range of the recess.
[0007]
Thereby, while holding the object such as water meter parts in the holding part of the immersion housing case, the entire immersion storage case is immersed in a predetermined liquid, and when the case is swung in the liquid, The object moves relatively with respect to the holding part in the range of the gap between the protruding part and the recessed part on both sides of the object, and the liquid is easily brought into contact with the entire surface of the object.
[0008]
Normally, it is considered important to fix and hold the object without play, but conversely, a gap (recess) necessary to actively move (swing, etc.) the object is formed. As a result, it is possible to prevent as much as possible that the liquid does not touch a part of the object (for example, a supported part) in the dipping process or that air remains in the cavity and the liquid does not rotate there. it can.
[0009]
In addition, when an object is put in a conventional basket for immersion and immersed, the object is easily scratched. On the other hand, if this immersion container case is used, the movement of the object is moderately regulated. Since the collision between the objects is avoided, there is also an effect that the objects are hardly damaged.
[0010]
Moreover, since this case can be used not only for the dipping process but also for transport and storage, the case that has been transported can be immersed in the liquid as it is, and then the object can be transported in the case. Not only is the dipping process improved, but the efficiency of transportation between processes or between plants is dramatically improved.
[0011]
Further, in the present invention, the object is supported at the bottom of the case, and the protrusions on both sides of the object are received in a state of being floated by the recesses of the holding part, whereby the position of the object is defined by the recesses, and The movement with respect to the holding part of the object is allowed in the recess, and the protrusions on both sides of the object do not touch the lower end of the recess, so that the liquid adheres sufficiently to the outer periphery of the protrusion when dipping, In addition, when the object moves (swings or slides, etc.) with respect to the bottom of the case via the swinging of the case, the liquid also flows to the part of the target that is supported by the above-mentioned case bottom, and good liquid processing is performed. it can.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the examples shown in the drawings.
The immersion housing case 1 shown in FIGS. 1 and 2 has a rectangular case main body 2 and a holding portion 3 formed inside thereof, and the holding portion 3 extends parallel to the side portion of the case main body 2. Two or more plates 4 (10 in this example) are provided, and each holding plate 4 is reinforced by a reinforcing plate 5 orthogonal thereto. More specifically, ten holding plates 4 are provided in the case body 2 in parallel with the side 2a on the short side of the case body 2, and two in parallel with the side 2a on the long side of the case body 2. The reinforcing plate 5 is provided. In this example, the main body case 2 and the holding portion 3 are formed separately, and the main body case 2 has a holding plate 4 and a reinforcing plate 5 incorporated therein. The case main body 2 is formed of a resin such as polypropylene. The holding plate 4 and the reinforcing plate 5 are formed of a resin such as hard urethane, and both have liquid resistance against the liquid to be immersed.
[0013]
Each holding plate 4 is formed with a plurality of recesses 6 at predetermined intervals for receiving protruding portions of a water meter lower case (water meter component) as an object to be described later. The projecting portions on both sides of the steel plate enter through a predetermined gap, and the component can swing in the same direction with respect to the holding plate 4 by swinging in a direction parallel to the holding plate 4.
[0014]
Specifically, as shown in FIG. 3A, the holding plate 4 is provided with a plurality of (four in this example) concave portions 6 at predetermined intervals in the longitudinal direction, and for assembling with the reinforcing plate 5. Have two cuts 7. Each recess 6 is tapered so that the upper side is slightly opened. When the holding plate 4 is punched with a Thomson blade or the like, the product can be easily taken out, and the protruding portion of the water meter component is recessed. 6 is easy to insert.
[0015]
Further, as shown in FIG. 5B, the reinforcing plate 5 has a plurality of cuts 8 in the longitudinal direction, and these cuts 8 are formed at 10 locations in order to be combined with 10 holding plates 4 in an intersecting state. Yes. The notch 8 of the reinforcing plate 5 and the notch 7 of the holding plate 4 are inserted into each other so as to have the same height H, and the upper end of each holding plate 4 and the upper end of each reinforcing plate 5 (the bottom of the lower notch 11) are substantially flat. The lattice structure becomes one. In addition, a plurality (five) of notches 9 are formed between the predetermined notches 8 on the lower edge of each reinforcing plate 5, and when these notches 9 are immersed in the liquid, It becomes a liquid circulation part (liquid passage) through which the liquid flows. As a result, even if the inside of the case is partitioned by the reinforcing plate 5, the liquid flows smoothly in a direction intersecting (orthogonal to) the reinforcing plate 5. In addition, the protrusion 10 which protrudes to the side is formed in the both ends of the reinforcement board 5, respectively, and these protrusion 10 fits in the mesh hole 2c of the mesh structure in the side part 2a of the case main body 2 shown in FIG. Thus, the reinforcing plate 5 and thus the holding plate 4 are fixed to the case body 4.
[0016]
7 to 10 show a lower case (in this example, having a diameter of 13 mm) 13 as a water meter component housed in the case. The lower case 13 has a cylindrical container shape, and has an upper opening 13a, sleeve portions 13e and 13f (tube portions) protruding from both sides, and a water outflow inlet that is an opening of the sleeve portions 13e and 13f. 13b and 13c. Water flowing from one of the outflow inlets 13b and 13c to the other rotates an impeller held rotatably through a pivot shaft 36 (see FIG. 9 (b)), and based on this rotational speed, The flow rate (usage amount) is detected. A pivot shaft 36 that rotatably supports the impeller is erected on the bottom of the lower case, and the impeller is loosely fitted and supported at the apex of the pivot shaft 36. The lower end of the pivot shaft is illustrated in FIG. 9 is screwed into a screw hole 13g (bottomed / non-penetrating) shown in FIG. Such a water meter is usually referred to as a single box water meter.
[0017]
As shown in FIGS. 4 and 5, the lower case 13 as a water meter component as described above is supported by the bottom portion 2b of the immersion housing case 2 with its opening 13a facing sideways, and predetermined with each other. The sleeve portions 13e and 13f of the lower case 13 are lifted in the recesses 6 corresponding to each other formed on the two holding plates 4 arranged at intervals (spaces narrower than the outer dimension between the sleeve portions of the lower case 13). Enter in the state. In other words, the lower end portion (bottom portion) of the recess 6 is made lower by a certain amount than the lower ends of the sleeve portions 13e and 13f, so that there is a certain amount of space between the lower ends of the sleeve portions 13e and 13f and the bottom portion of the recess 6. There is a gap. Further, the opening width of the recess 6 is determined so that a certain gap is secured also between the front and rear ends inside the recess 6 and the outer surfaces of the sleeve portions 13e and 13f.
[0018]
FIG. 6 schematically shows the relationship between the lower case 13, which is a water meter component, and the recess 6 of the holding plate 4. As is clear from this figure, the upper and lower gaps t1 and t2 between the sleeves 13e and 13f of the lower case 13 and the recess 4 in the state where the lower case 13 is housed in the immersion housing case 1. Is set, and the lower portion of the lower case 13 is seated on the case bottom 2b. FIG. 11 shows a state (20 in this example) in which the immersion housing case 1 of FIG. 1 is filled with a specified number of lower cases 13.
[0019]
Then, the plurality of immersion housing cases 1 are immersed in a predetermined liquid (for example, lead elution prevention treatment liquid) together with the frame cage in a state where they are stored in a predetermined frame cage (an assembly cage made of punching metal or the like). The More specifically, a frame cage is suspended by a crane or the like for a degreasing liquid tank, a water washing tank, a surface conditioning tank, a water washing tank, a chemical conversion treatment tank, a water washing tank, a hot water washing tank, etc. It will be immersed in each tank sequentially with the frame base.
[0020]
At the time of the immersion, the frame gauge is swung in a certain manner by a supporting means such as a crane, for example, so that the lower case 13 which is a water meter component in each immersion housing case 1 is shown in FIG. As shown in the concept, the case 13 is moved (swinged, slid, etc.) with respect to the case main body bottom 2b with reference to a plane parallel to the holding plate 4 with the opening 13a oriented substantially in the lateral direction. As a result, the lower case 13 serving as the housing component has a large relative flow of liquid on the outer surface side, and air is not easily trapped together with the inner surface side, so that it touches the liquid such as the processing liquid evenly on the outer surface side and the inner surface side. This makes it easy to perform good liquid processing that is less likely to cause missing portions of the liquid processing. In particular, in this example, the screw hole 13g of the pivot shaft 36 formed on the bottom portion of the lower case 13 shown in FIG. It is possible to avoid that air is trapped in the screw hole 13g (occurrence of an air pocket).
[0021]
Next, another embodiment of the immersion housing case will be described with reference to FIGS.
As shown in FIGS. 12 to 14 and the like, the immersion housing case 21 of this example includes a case main body 22 (this is the same as the case main body 2) and a holding portion 23 formed therein. The holding portion 23 includes two holding plates 24a and 24a along two side portions 22a in the long side direction of the case main body 22, a holding plate 24b that is parallel to them and crosses the center in the middle thereof, and the case main body. 22, two reinforcing plates 25 a and 25 a arranged along two side portions 22 a in the short side direction, and short reinforcing plates 25 b and 25 b arranged between the holding plates 24 a.
[0022]
As shown in FIG. 15, each holding plate 24a has a plurality of (five) concave portions 26 for holding water meter parts as objects to be described later at an upper portion at a predetermined interval, and at the lower portion. A plurality of (five) cutouts 31 that allow the liquid to flow are provided at an intermediate position between the adjacent recesses 26. In addition, the holding plate 24 a includes a downward notch 28 and protrusions 30 protruding laterally at both ends, and each protrusion 30 is fitted into a net hole in a side portion of the case body 22 and fixed to the case body 22. . This is the same as in FIG. Further, a downward notch (not shown) of the reinforcing plate 25a shown in FIG. 12 or the like is inserted into the notch 28 of the holding plate 24a, and they are combined so as to be orthogonal to each other.
[0023]
The central holding plate 24b has a structure that is fixed to the case main body 22 at protrusions (similar to the protrusion 30 of FIG. 15) formed at both ends thereof, and a reinforcing plate 25a at the upward cut formed at both ends. The structure in which the downward cut is inserted is the same as that of the holding plates 24a on both sides, but the form of the recess for receiving a sleeve portion described later of the water meter component is different. In the longitudinal direction of the central holding plate 24b, as shown in FIGS. 12 and 13, a plurality of convex portions 27 are formed upward at regular intervals, and a portion between the convex portions 27 is a plurality of concave portions at regular intervals. The number of recesses 28 in the central holding plate 24b is twice (10) the number of recesses 26 (5 in this example) in the holding plates 24a on both sides.
[0024]
That is, the central holding plate 24b is a holding plate facing the holding plates 24a on both sides in common. In the central holding plate 24b, recesses 28 corresponding to the recesses 26 formed on one holding plate 24a on both sides and recesses 28 corresponding to the recesses 26 formed on the other holding plate 24a are alternately ( In other words, the formation positions of the concave portions 26 of the holding plates 24a and 24a on both sides are shifted from each other by a predetermined pitch (in this example, a half pitch). Also in this example, the holding plates 24a and 24b and the reinforcing plates 25a and 25b are formed of a resin such as hard polyurethane, and have liquid resistance against the liquid to be immersed together with the case body 22 from a resin such as polypropylene.
[0025]
An example of the water meter part of the target object accommodated in the immersion housing case 21 as described above is shown in FIGS. 19 and 20. This is a lower case 33 constituting a water meter housing, and the upper case is assembled to the upper opening 33a. Sleeve portions 33e and 33f (tube portions) are provided as projecting portions projecting laterally from both sides of the central portion, and the respective end portions serve as water outflow inlets 33b and 33c (this example has an opening diameter (bore diameter)). ) Is, for example, 20 mm). In this case, water flows through 33c as the inlet and 33b as the outlet, and the flow rate (water usage) is measured based on the number of rotations of the impeller rotating by the water flow. Such a water meter is usually referred to as a double box water meter.
[0026]
The lower case 33 is formed with an inner flange 33h (see FIG. 19B) for assembling a measuring chamber case or the like. When the lower case 33 is immersed in a predetermined liquid, an opening 33a is provided for the inner flange 33h. The structure makes it difficult for liquid to enter the case bottom. In such a case, it can be said that when the lower case 33 is swung with reference to a plane parallel to the axis of the outflow inlets 33b and 33c, the processing liquid can easily turn into the inside. That is, the lower case 13 shown in FIG. 7 and the like is based on the assumption that the lower case 13 is swung with respect to a plane perpendicular to the axis of the outflow inlets 13b and 13c. In 33, it can be said that the direction of oscillation differs by 90 degrees.
[0027]
16 and 17 show a state in which only one lower case 33 as described above is placed in the immersion housing case 21, and FIG. 21 shows a lower number of the immersion housing cases 21 (10 in this case). The state filled with case 33 is shown. FIG. 18 schematically shows the accommodation state of the lower case 33, which is a water meter component, with respect to the immersion accommodation case 21. As is clear from this figure, the lower case 33 is set between the holding plates 24a and 24b in a state where the opening 33a is turned down and the bottom is turned up.
[0028]
More specifically, the end surface of the opening 33a is seated on the bottom of the case main body 22 to support the weight, and the sleeve portions 33e and 33f protruding to both sides are provided to hold the concave portion 26 of the side holding plate 24a and the center. It enters (accepts), in a so-called floating state, into the concave portion 27 of the plate 24b through a gap s1 in the height direction (up and down) and a gap s2 in the horizontal direction (front and back). In other words, the bottom portions (bottom surfaces) of the concave portions 26 and 27 are formed lower than the lower ends of the sleeve portions 33e and 33f, and the sleeve portions 33e and 33f have a tapered shape in which the base side is thicker. However, since the width (frontage) of each of the recesses 26 and 28 is formed wider than the tapered outer shape by a certain gap, the lower case 33 has shafts of sleeve portions 33e and 33f with respect to the holding plates 24a and 24b. It is possible to move in a direction by a predetermined small distance.
[0029]
Then, the immersion housing case 21 that accommodates the plurality of lower cases 33 in this manner is put in the frame gauge as described above and immersed in the treatment liquid in the same manner as described above, and the holding plate 24a in FIG. When it is swung in a direction opposite to 24b, as shown in FIG. 18C, the lower case 33 reciprocates so as to slide on the bottom of the case main body 22 while swinging together with the case main body 22. The processing liquid sufficiently contacts the seating portion of the lower case 33 with respect to the case main body 22, and the liquid spills into the lower case 33 regardless of the presence of the inner flange 33 h in FIG. 19B. It becomes easy.
Therefore, the liquid sufficiently contacts both the inside and the outside of the upper case 33, and a good liquid processing that does not easily cause a liquid missing portion is possible.
[0030]
As yet another embodiment, FIG. 22 shows a predetermined number, for example, 12 lower cases 43 (for example, a long type having a diameter of 13 mm) in which sleeve portions 13e and 13f on both sides of FIG. An immersion housing case 41 for housing is shown. The case main body 2 is the same as that of the above-described embodiment, and the internal holding portion is different from that shown in FIGS. 1 and 2 and the like in that the holding plate 4 has a longer span. The number of 4 is reduced from 10 to 6, and the other parts are the same as those in the above-described embodiment, and are substantially the same as the immersion housing case 1 shown in FIG. Is obtained.
[0031]
In another embodiment shown in FIG. 23, the upper case 33 shown in FIG. 19 or the like as an object to be accommodated has an enlarged diameter, and the lower case 53 (for example, a 25 mm long diameter) whose overall water passage has been increased. A dipping housing case 51 that houses a predetermined number, for example, eight. The case main body 2 is the same as that of the above-described embodiment, and the internal holding portion is different from FIGS. 12 and 13 in that the number of concave portions 26 of the holding plate 24a is changed from five to four. The reduced holding plate 34a and the holding plate 34b in which the number of concave portions 28 of the holding plate 24b is reduced from 10 to 8 are used. The reinforcing plates 35a and 35b are the same as the reinforcing plates 25a and 25b described above. In this example as well, substantially the same effects as those shown in FIG. 12 and the like can be obtained.
[0032]
In addition, although the above immersion storage cases 1, 21, 41, and 51 are changed according to the size and shape of the water meter parts to be stored with respect to the internal holding portion, the case main bodies 2 and 22 are all It is common throughout. When dipping in a predetermined liquid tank, as described above, a frame gauge 60 (for example, a plurality of liquid-permeable shelves such as punching metal, etc.) is formed as conceptually shown in FIG. In each shelf, a submerged storage case (No. 1 to No. 15 in this example) containing predetermined water meter parts (lower cases 13, 33, 43, 53, etc.) is stored. When the frame gauge 60 is swung in one direction, for example, along the short side direction of the dipping container case, with the hanging means or the dedicated rocking means in a state where the frame gauge 60 is immersed in the liquid tank by a hanging means such as a crane. As described above, the liquid around the object is improved.
[0033]
Here, in FIG. 1-No. The 15 cases may be of the same type (for example, only a plurality of immersion housing cases 1), or may be any combination of different types (for example, immersion housing cases 1, 21, 41, 51). For example, if the immersion housing cases 1 and 21 are mixed and placed in a frame cage and immersed in a liquid tank and swung in one direction (may be a plurality of directions), the above-described case is shown in FIG. Such a swing along the direction parallel to the holding plate 4 of the lower case 13 and a swing along the direction perpendicular to the holding plate 24a of the lower case 33 as shown in FIG. . In other words, the lower case 13 in FIG. 6 swings along a direction perpendicular to the axial direction of the sleeve portions 13e and 13f, and the lower case 33 in FIG. 18 extends along a direction parallel to the axial direction of the sleeve portions 33e and 33f. Oscillation occurs and the surroundings of the liquid can be improved according to the form and structure of the upper cases 13 and 33.
[0034]
Although the above has mainly explained each immersion container case by focusing on dipping in a predetermined liquid tank, the immersion container case as described above stores or transports (transports) objects such as water meter parts. ) Can also be used as is. At that time, at least the plane size of the case main body is common in the above-described immersion housing cases 1, 21, 41, 51. Then, as shown in FIG. 25, the bottom portion of the case body is provided with a fitting portion 70 at the time of stacking that protrudes downward and is provided in a square shape or only at four corners when viewed from the bottom. In this state, the fitting portion 71 at the bottom of the case is fitted and positioned inside the case opening 17.
[0035]
Accordingly, a plurality of cases 1 and the like containing objects such as the water meter parts can be stored in a stacked state as described above, or transported on a truck or the like. Has liquid resistance and liquid permeability with respect to a predetermined liquid, so that the above-mentioned liquid can be left as it is through the frame gauge or the like without being taken out of the object contained in the case 1 or the like or in a stacked state. Since immersion in a tank can be performed and the object after immersion can be stored and transported while being accommodated in the case 1 or the like, work efficiency is greatly improved.
[0036]
In the above description, the case main body 2, 22 and the holding portions 3, 23 are separately formed in the immersion housing case, and the case main body and the holding portion (reinforcing portion) are described. May also be formed integrally. For example, integral molding with resin is also possible.
