【0001】
【発明が属する技術分野】
この発明は、供給室内の海苔混合液を隙間に通して排出室内に流し、隙間より大きな小エビや小貝等の異物を供給室に残し、供給室内に溜まった異物を供給室から排出するようにした海苔異物除去方法及び装置に関する。
【0002】
【従来の技術】
この種の海苔異物除去装置は、特開平6−121660号公報等に開示されているように、海苔原料液(海苔混合液)を貯留可能な貯留タンク内の供給室に外壁の少なくとも一部に生海苔の厚みより僅かに大きい孔幅の細長い分離孔を有する異物分離器を配設し、その異物分離器内の排出室に排出ポンプを連結し、排出室内の海苔原料液を吸引して貯留タンク内の海苔原料液を分離孔を通して排出室内に吸引し、分離孔の孔幅より薄い生海苔を分離孔に通過させ、それより大きな異物を分離孔に係止させて供給室に残して除去するようにしてある。
【0003】
そして、異物除去作業を所定時間継続した結果、供給室内の異物が増大して異物除去の処理能力が低下した場合には、海苔異物除去装置の作動を一時停止し、供給室の底部に設けた排出孔の栓(コック)を開けて供給室内の海苔混合液を外に排出して供給室内の異物を除去し、その後栓を閉じて供給室に新たな海苔混合液を供給して海苔異物除去作業を再開している。
【0004】
【発明が解決しようとする課題】
上記従来装置においては、供給室内の異物が増大した場合に、海苔異物除去装置の作動を一時停止し、供給室の海苔混合液をそのまま排出孔から外に排出しているので、供給室内の海苔混合液に混入している多くの生海苔が異物と共に廃棄されて無駄になる経済的な問題があり、また供給室内の海苔混合液の排出に長い時間を必要として異物除去作業の停止時間が長くなり、異物除去装置の稼働率が低下する問題がある。また、従来装置においては、供給室の底部に異物が生海苔と共に付着しており、供給室内の海苔混合液を排出した後も供給室内を人手によって清掃する手間を必要とし、その作業が面倒である問題もある。
【0005】
【課題を解決するための手段】
そこで、本発明は、供給室内の海苔混合液を隙間に通して排出室内に流し、隙間より大きな異物を供給室に残し、供給室内に溜まった異物を供給室から排出するようにした海苔異物除去方法において、供給室内に残される異物入り海苔混合液を所定の設定時間毎に自動的に排出するものであって、その供給室内に溜まった異物入り海苔混合液を排出するに先立ち、供給室内の海苔混合液を排出室に流す作業を継続した状態で、供給室内への海苔混合液の供給を所定時間停止し、供給室内の海苔混合液の液面が所定の高さ迄低下した時点を検出したとき、供給室内に水を所定時間供給することによって海苔混合液の濃度を薄くし、その後、供給室内の海苔混合液の液面が所定の高さ迄低下したことを検出したとき、供給室内の海苔混合液を排出室に流す作業を停止すると共に供給室内の異物入り海苔混合液を所定時間排出し、供給室内に残される海苔混合液の生海苔の量を少なくして異物入り海苔混合液を自動排出することを特徴としている。

【0007】
また、本発明は、生海苔の海苔混合液を供給する供給室と生海苔の海苔混合液を排出する排出室とを、生海苔の厚みより大きくて除去すべき異物より小さい隙間を有する分離壁によって区切り、供給室に海苔混合液を供給する液供給手段と、排出室から海苔混合液を排出する液排出手段とを備えた海苔異物除去装置において、供給室に水を供給する給水手段を設け、供給室の底部に異物入り海苔混合液を排出可能な異物排出ポンプの吸引口を連結して供給室から異物入り海苔混合液を排出可能な異物排出手段を設け、異物排出手段の異物排出ポンプが所定時間毎に作動する作動時間を制御するタイマを備え、異物排出手段の作動に先立し、液排出手段が供給室内の海苔混合液を排出室に流す作業を継続した状態で、液供給手段による供給を停止し、供給室内の海苔混合液の液面が所定の高さ迄低下したとき、給水手段による水供給を所定時間行い、その後供給室内の海苔混合液の液面が所定の高さ迄低下したことを検出したとき、液排出手段による海苔混合液の排出を停止すると共に異物排出手段の異物排出ポンプを所定時間作動させて異物を排出するように制御する制御装置を備え、所定の設定時間毎に供給室内の海苔混合液の生海苔量を少なくして異物入り海苔混合液を自動排出するようにしたことを特徴としている。
【0008】
【発明の実施の形態】
図において、Aは海苔原料液(海苔混合液とも言う)から異物を除去するための異物除去ユニット、Bは異物除去後の海苔原料液を一時貯留して海苔原料液内の極めて小さな異物を除去して高品質の海苔原料液を得ると共に水(真水または海水の何れをも意味する。)を還流して海苔混合液の濃度を濃くするための仕上ユニットで、ユニットA、Bは一体に設けられているが、分離して設けても良い。Cは、水還流ユニットで、水タンク1内に水を通過させるも異物を通過させない漉し網等のフイルター2が着脱自在に配置して構成してある。水タンク1は、場合によっては既設の水槽を利用しても良い。水還流ユニットCは後述の水還流手段85の一部を構成している。水還流ユニットCはユニットA、Bと一体に設けても良い。
【0009】
先ず異物除去ユニットAについて説明する。3は、支持枠4を介して支持されている貯留タンクで、海苔混合液を貯留可能な箱型に形成され、貯留タンク3の下方には収容空間5が形成されている。
貯留タンク3内には多数の小さな連通孔6aを有する環状(八角形)の仕切壁6がその壁板を上方へ抜き差しして交換可能(固定的に設けても良い)に設置され、貯留タンク3内を内側の供給室7と外側の排水室8に区切っている。仕切壁6の連通孔6aは海苔原料液の生海苔は通さないが水や極めて小さな異物は通す大きさ例えば直径2mm程度の大きさの丸孔に形成されているが、その形状や大きさは任意に変更しても良い。仕切壁6は市販のパンチングメタルを用いても良く、その場合仕切壁6の一部のみに用い他を単なるプレートで構成しても良い。仕切壁6は宙吊り状態の箱型に設けても良い。
【0010】
供給室7及び排水室8の底部には異物入り海苔混合液を排出可能な異物排出手段10が設けられている。異物排出手段10において、11、12は供給室7及び排水室8の底部に設けた比較的大きな異物排出口で、異物排出ポンプ13の吸引口に夫々ホース14a、14a‘を介して連結されている。異物排出ポンプ13の吐出口は水還流ユニットCの水タンク1内に設けたフイルター2内にホース14bを介して連結されている。異物排出手段10は図示しないタイマによって設定時間毎例えば1時間毎とか2時間毎等に作動するようにしてあり、その場合他の手段と共に所定の作動を行うように後述の制御装置150によって制御されるようになっている。
【0011】
供給室7内の中央部付近には上下側が閉鎖されている閉鎖筒状の異物分離器15が軸線が上下方向になるように固定的に設置されている。この異物分離器15は図4、5に示すように排出室16を形成する中空容器17を備えている。中空容器17の周壁は筒状体22によって構成され、筒状体22に複数の開口部23が形成されると共に外周面に小さなピッチ例えば5.4mmピッチの螺旋溝24が形成されている。筒状体22の外周に例えば直径5mmのステンレス製の線材25が螺旋溝24に嵌まり込むように螺旋状に巻付けられ、線材25の両端部は筒状体22に螺子で挾んで固着されている。
線材25は異物分離器15の内外を区切る分離壁27を構成し、また開口部23には螺旋状に巻付けられた隣合う線材25相互間の隙間によって生海苔の厚みより僅かに大きい孔幅(図の場合0.4mm)の細長い分離孔28(隙間とも言う。)が形成されている。なお、前記分離孔28の形成は、筒状体22の外周面に例えば1.4mmの螺旋溝24を形成し、筒状体22の外周に例えば直径1mmのステンレス製の線材25を螺旋溝24に嵌まり込むように螺旋状に巻付けるようにしても良く、種々の実施の形態がある。
【0012】
分離壁27は中空容器17内の排出室16と中空容器17外の供給室7を区分している。筒状体22にはほぼ円錐形の底壁29が一体に成形され、筒状体22の上側には蓋板30が固着されている。底壁29には海苔原料液を排出する為の一対の排出孔26a、26aが形成されている。
上記分離孔28の大きさは、生海苔の厚みや大きさが採取時期や切断の仕方によって異なるので、上記数値に限定されるものではなく、孔幅を例えば0.3mm程度に小さくしたり、例えば1mm程度に大きくしたり、長さを例えば20mm程度に短くしたり、例えば50mm程度に長くしたり、分離孔28を環状或は螺旋状の連続隙間にしても良い。また、分離孔28は、並設した固定的または回動可能な棒材や固定的または回動可能なプレートで構成する等任意に変更しても良い。
【0013】
次に、31は供給室7内に前工程から海苔混合液を供給する液供給手段で、供給管32aと供給ポンプ32bとで構成され、粗切り(又は細かく切断)された生海苔を水に混合させて成る海苔原料液を供給するようになっている。液供給手段31の供給ポンプ32bは、後述の仕上ユニットBの排出作動とほぼ連動して作動するように制御され、またその作動はタイマー等で例えば3秒間作動した後例えば6秒間停止する1サイクルをり返すように制御される。
【0014】
33は異物分離器15の排出室16内の海苔混合液を強制排出する液排出手段で、水を吸引可能な一対のモータ付排出ポンプ34と、排出ポンプ34の吸引力を上記排出口26a、26aに交互に作用させるための切換弁を構成する回転切換弁35とを備えている。回転切換弁35は、図6、7に示すように、筒型の弁本体36内に回転弁室37を設けると共にその弁本体36の周壁の相対向する位置に2つの供給ポート38を設けてある。また一方の側壁には回転軸39を軸受40を介して回転自在に支承し、他方の側壁には1つの排出ポート41を設け、回転弁室37内に回転軸39に固着されている回転弁体42を回転自在に設けてある。回転弁体42は回転弁室37の内面に沿って回転する筒型に形成され、その一部は回転中心に対する開き角度が150度程度の開口部42aが形成され、2つの供給ポート38を選択的に開放するようになっている。回転軸39にはプーリ43が固着され、プーリ43が可変速の駆動モータ44の駆動軸44aに設けた駆動プーリ45によってベルト46を介して回転されるようになっている。2つの供給ポート38は夫々排出室15の排出孔29aに連結ホース47を介して連結されている。
【0015】
上記一対の排出ポンプ34は、吸引孔どうしが連結管51によって連結されると共に吐出孔どうしが連結管52によって連結されており、吸引側の連結管51の中央部が回転切換弁35の排出ポート41にホース53を介して連結されている。吐出側の連結管52の中央部には排出ホース54の一端が連結されている。排出ホース54の他端は貯留タンク3の側片3aに立設した一対の連結管55、56の一方の下端に連結されている。連結管55、56の上端には透明または半透明の透視連結管57が連結され、内部を流れる海苔原料液の状態を目視できるようにしてある。他方の連結管56の下端は、仕上ユニットBの貯留室90の底部に設けた曲折供給管58にホース59を介して連結されている。
一対のモータ付排出ポンプ34によって排出するようにしているので、小型のモータ付ポンプによって排出能力をきわめて大きくでき、その結果装置をコンパクトにできる。
【0016】
一対の排出ポンプ34は、図示しない制御ボックス内に設ける制御装置により所定時間例えば4秒間吸引運転した後所定時間例えば3秒間吸引を停止する1サイクルを繰り返すようになっている。この排出ポンプ34が断続運転する場合の運転時間や停止時間はタイマー等によって容易に設定可能にしてあり、各時間の長さも任意に例えば2秒間運転して1秒間停止するように変更可能にしてある。なお、排出口26aを1つ設け、排出ポンプ34を1つとし、排出ポンプ34の吸引口を排出口26aにホースを介して直接連結しても良い。
60は供給室7に水を補給するための給水手段で、水還流ユニットCの水タンク1内に配設した給水ポンプ61の吐出口に連結されている給水ホース62の端部が供給室7内に臨むように配設され、給水ポンプ61の作動により供給室7内に水を補給するようにしてある。
【0017】
66は排出室16から異物分離器15の分離孔28に向けて水を噴射して分離孔28の詰まりを清掃する水噴射手段(清掃手段)で、貯留タンク3に固着されている支持枠67に設けた軸受68と異物分離器15の蓋板30に設けた軸受69によって回転自在に支承されている中空の回転軸70(給水管とも言える)と、異物分離器15内に挿入されている回転軸70の下部両側に夫々半径方向へ張り出すように固着されている複数の噴射ノズル71と、回転軸70の上端部に回転継手72と供給ホース73を介して連結されている一対の供給ポンプ74、75とを備えている。回転軸70には撹拌翼70aが設けられている。
供給ポンプ74、75は直列に連結され、一方の供給ポンプ74の吐出口は供給ホース73に連結され、吸引口は他方の供給ポンプ75の吐出口にホース76を介して連結され、他方の供給ポンプ75の吸引口は水タンク1の底部にホース77を介して連結されている。回転軸70にはスプロケット78が固着され、支持枠79に設けられている駆動モータ80によってスプロケット81とチェーン82を介して低速回転されるようにしてある。
一対の供給ポンプ74、75によって水を供給するようにしているので、小型の供給ポンプによって極めて大きな水噴射力を出すことができ、その結果供給ポンプの収納スペースを小さくできて装置をコンパクトにできる。
【0018】
供給ポンプ74、75の能力は、噴射ノズル71が分離孔28(隙間)に対して排出室16から供給室7に向けて水を噴射させる噴射力が排出ポンプ34による分離孔28(隙間)の吸引力より大きくなる能力で水を供給し、噴射水が分離孔28を通して供給室7内に高圧で噴出して供給室7内の海苔原料液に打ちたたくような激しい衝撃力を与えるようにしてある。また、噴射水の水量が一対の排出ポンプ34による排出量より多くなり、供給室7内の海苔原料液の水量が増えて水と小さな異物が連通孔6aから排水室8に流れるようにしてある。従って、水噴射装置66は供給室7内に水を供給可能な給水手段をも構成している。
上記水噴射装置66は、仕上ユニットBや水還流ユニットCと共に排出室16から吸引した海苔原料液の水を供給室7に還流するための水還流手段85を兼用しており、供給ポンプ43の吸入口が水タンク1にホース49を介して連結されている。水噴射装置66は還流水に代えて新たな海水や井戸水や水道水等を噴射するものでも良い。
【0019】
次に、仕上ユニットBについて説明する。88は貯留タンクで、上方が開放されている平面形状多角形(八角形)の箱形に形成されている。貯留タンク88内には多数の小さな連通孔89aを有する環状(八角形)の仕切壁89が壁板を上方へ抜き差しして交換可能(固定的に設けても良い)に設置され、貯留タンク88内を内側の貯留室90と外側の排水室91に区切っている。仕切壁89は小さな異物を通すが生海苔を通さない多数の小さな連通孔89aを有する分離壁を構成している。貯留室90は、貯留タンク68内に宙吊り状態に設けた分離容器によって構成し、その底板及び側板を多孔板(例えばパンチングメタル)によって構成しても良い。連通孔89aの径の大きさは、1mm程度〜3mm程度の範囲の所望の大きさに設定されている。
貯留室90と排水室91の底部には図示しない異物排出口が設けられ、それらの異物排出口に必要時に開放可能なバルブを有する排出管が連結されている。なお、沈殿する異物量が多いときは、前記異物排出手段10と同様に構成すると良い。貯留室90の底部には、海苔混合液を供給可能な前記曲折供給管58と海苔混合液を次工程に排出可能な曲折排出管93が上方突出するように配設されている。曲折排出管93の他端部は移送ホース94を介して送給ポンプ95の吸引口に連結されている。曲折排出管93が突出しているので、貯留室90内の底部の小さな異物が次工程に供給されるのを防止できる。
【0020】
96は貯流室80内に供給された海苔混合液を撹拌する為の撹拌装置である。この撹拌装置96において、97は貯留室90の中心部を貫通するように配設されている撹拌軸で、貯留タンク88の底板に設けた軸受98と貯留タンク86に固着されている支持枠99に設けた軸受100によって回転自在に支承されている。撹拌軸97には撹拌翼102が固着されている。撹拌翼102は貯留室90内の海苔混合液を仕切壁89に押圧するように形成されている。
撹拌軸97の上端部は、支持枠99に取着されている正逆転可能でかつ変速可能な上記駆動モータ105の駆動軸105aに連結されている。駆動モータ105は支持枠79に取着されている制御装置150によって所定時間例えば10秒(この時間は任意にに設定できるようにしてある。)置きに正転と逆転を繰返すように制御される。
【0021】
次に、106は図1、2に示すように貯留タンク3、88の側面に一体に固着されている還流槽で、細長い箱形容器に形成されている。還流槽106に対向する貯留タンク3、88の側壁には排水窓107、108が夫々設けられている。排水窓107、108の下側部分には溢水板107a、108aが高さ位置調整可能に取付けられ、排水室8、91内の液面が上限又は上限近くになったときにオーバフローさせるようにしてある。還流槽106の底壁には排出孔110が設けられ、この排出孔110にホース111が連結されている。ホース111の他端部は還流ポンプ112の吸引口に連結され、還流ポンプ112の吐出口に連結したホース113の端部が水タンク1内のフイルター2内に配置され、還流槽106内の水を水タンク1内に回収するようにしてある。還流槽106を2つの貯留タンク3、88の側面に設け、両方の貯留タンク3、88の水を同時に回収するようにしたので、装置の構成を簡易にできると共に小型化できる。
【0022】
117は供給室7内の海苔原料液の液面の高さが所定高さまで低下したことを検出する検出装置で、貯留タンク3の底部と連通するように立設した透明樹脂材料から成る検出管118と、検出管118内に水に浮いて上下動可能なように収納した浮子119と、検出管118の下部に浮子119の位置を検出可能に設けた光電式の検出スイッチ120とで構成されている。121は、は貯留室90内の海苔原料液の液面の高さを検出する検出スイッチで、海苔原料液の濃度が濃くなって液面の上限を検出すると排出ポンプ34の作動を停止して貯留室90内への海苔原料液の供給を停止し、液面の下限を検出すると汲み出し用の送給ポンプ95の作動を停止して海苔原料液の汲み出しを停止するようになっている。
【0023】
上記海苔異物除去装置は、海苔製造工程における原藻洗い工程と洗浄原藻切断工程の間や、原藻粗切断工程と原藻細切断工程との間、原藻切断洗浄工程と海苔切断洗浄脱水工程の間、海苔切断洗浄脱水工程と海苔熟生脱水工程の間、海苔熟生脱水工程と海苔調合工程の間又は海苔調合工程と海苔抄造工程との間等に組み込んで使用する。
使用に際しては、異物除去ユニットAにおいて、予め水タンク1と貯留タンク3内に水を適当量供給した状態で、液供給手段31によって前工程から海苔原料液を供給室7に供給する。供給室7内の海苔混合液の生海苔の一部と水の一部は分離孔28を通して排出室16に入り、海苔原料液の水と小さな海苔くず等の異物は仕切壁6の連通孔6aを通して排水室8に入る。供給室7内への海苔原料液の供給は供給手段31の供給ポンプが予めタイマー等で設定した所定時間断続運転することによって行われる。一方仕上ユニットBの貯留タンク88に適当量例えば8割程度水を供給しておく。
【0024】
この状態で液排出手段33の駆動モータ44及び一対の排出ポンプ34と水噴射手段66の供給ポンプ74、75を作動させ、また駆動モータ80を作動させて噴射ノズル71を矢印方向へ回転させる。排出ポンプ34の作動は間欠的に例えば3秒間作動した後3秒間停止する1サイクルを必要時間繰り返す。従って、排出室16内の海苔混合液が3秒間おきに3秒間づつ間欠的に強制吸引される。また、駆動モータ44の作動により回転弁体42が回転し、排出ポンプ34の吸引口を一対の排出孔29aに例えば1秒置きに交互に連通させる。排出室16内の海苔原料液が一対の排出孔29aから交互に間欠的に強制吸引されると、供給室7内の海苔原料液が分離孔28から排出室16内に間欠的に強制吸引されると共にその吸引力が変動され、生海苔と水が分離孔28から排出室16内に流入され、分離孔28の隙間より大きな異物は分離孔28に係止されて供給室7に残される。
【0025】
排出ポンプ34によって吸引された海苔混合液はホース54、透視連結管57、ホース59等を介して仕上ユニットBの貯留室90に供給される。水噴射手段66の供給ポンプ74、75が作動されると、水タンク1内の水を吸引して回転軸70から各噴射ノズル71に供給し、噴射ノズル71の噴射孔から水を連続的に噴射する。噴射ノズル71は分離壁27に対して回転しているので、各分離孔28には噴射水が周期的に連続的に噴射され、その結果、分離孔28に詰まっている生海苔や異物が分離孔28から供給室7内に噴出されて分離孔28が連続的に完全に開放され、新たな生海苔が分離孔28から排出室8に効率よく流入するようになる。また、分離孔28から供給室7内に高圧の噴射水が噴出され、供給室7内の海苔原料液が高圧の噴射水によって衝撃力を加えられ、その結果、海苔原料液の生海苔が噴射水に打ちつけられて表面がきれいに洗浄され、生海苔の表面に食い込んでいた小エビ等の異物が生海苔から離脱される。
【0026】
分離孔28は、生海苔の厚みより僅かに大きな寸法の孔幅を有する細長い形状に設けてあるので、海苔原料液の生海苔は水と共に分離孔28から排出室16内に流入するが、分離孔28の孔幅より大きな寸法の小エビや小貝等の異物は分離孔28の孔縁によって係止されて供給室7内に残される。分離孔28の孔幅は生海苔の厚みより僅かに大きな大きさ例えば0.4mm程度に形成してあるので、排出室16内に入った海苔原料液の中には例えば0.4mm程度以上の異物が全く無くなる。
供給室7内の海苔原料液が分離孔28から排出室16内に積極的に吸引されることによって、生海苔が分離壁27外周に付着して分離孔28を塞ぐ現象を示すが、回動する噴射ノズル71の噴射孔から分離壁27の全周に亘って連続的に水が噴射されており、しかも排出室16に作用する吸引力が間欠的に停止されるので、分離壁27に吸着された生海苔や異物は噴射ノズル71からの高圧の水噴射によって確実に離脱されて供給室7に拡散され、分離孔28の詰まりが完全に解消されて生海苔の流入が極めて良くなる。このことは単位時間当りの海苔異物除去能力を大幅に向上させる。
【0027】
また水噴射手段66の供給ポンプ74、75の能力を排出手段33の排出ポンプ34の能力より大きくしてあるので、排出ポンプ34が排出室16内の海苔原料液を吸引しているときでも供給室7内の海苔原料液の水量は増加する。ところが、供給室7内の海苔原料液の水と小さな異物は仕切壁6の連通孔6aから排水室8に出て、水と共に泡や軽いごみが排水窓107から還流槽106内に溢れ出されるので、供給室7内の水と小さな異物が連通孔6aから排水室8に大量に流れる(水が循環される)ことになる。その結果供給室7内の海苔原料液から小さな異物が効率良く除去され、また供給室7内の海苔原料液内の小エビ等の軽い異物が仕切壁6の内周面に付着して分離除去される。還流槽106内に回収された異物入り水は還流ポンプ112によってホース111、113を介して水タンク1内のフイルター2内に供給され、きれいな水が水タンク1内に回収される。
【0028】
排出ポンプ34によって排出室16内の海苔原料液が吸引されると、供給室7内の海苔原料液の濃度が薄くなるので、排出ポンプ34による吸引排出に連動して或は略連動して液供給手段31によって海苔原料液が供給室7に供給される。還流ポンプ112は還流槽106内の水を図示しない検出スイッチに基づいて自動的に水タンク1内に回収するが、このように還流槽106から水が回収されているので、液排出手段33による排出の際に大量に使用する水量を水タンク1に補給できて使用水量を節減できて経済的である。
【0029】
次に、仕上ユニットBにおいては、貯留室90内の液面が上限に達したことを検出スイッチ121が検出すると、液排出手段33の排出ポンプ34の運転を停止させる。この場合、排水窓108の溢水板108aの高さが検出スイッチ121の上限の高さより僅かに低くなるように設定してあるので、貯留室90内の海苔原料液の濃度が低いときは分離容器70の小孔89aから水と小さな異物が外に流れて排水窓108から溢れ出し、貯留室90内の水位が上昇しないので、上限を検出することはない。
ところが、濃度が高くなると、小孔89aから水と小さな異物が外に流れ出にくくなり、貯留室90内の水位が高くなり、上限を検出して排出ポンプ34による海苔原料液の供給が停止されると共に液供給手段31による供給室7への海苔原料液の供給が停止される。貯留室90内では、駆動モータ105が常時駆動することによって撹拌翼102を交互に正転・逆転させる。撹拌翼102が正転と逆転を所定時間毎に繰り返すことによって、海苔原料液が撹拌されて生海苔に付着している小さな異物が分離され、分離した小さな異物が小孔89aから排水室91に押し出される。
【0030】
貯留室90内での海苔原料液の撹拌を所定時間例えば5分程度(この時間は任意であり、特定されるものではない。)行うことで、海苔原料液に混入している小さな異物が貯留室90外に出されて除去され、貯留室90内には異物除去された生海苔と水の良質の海苔原料液が残される。その後、送給ポンプ95を作動させて貯留室90内の海苔原料液を曲折排出管93及びホース94を介して次工程に移送し、この海苔原料液が海苔抄造に使用される。貯留室90から外側に出された排水室91内の海苔原料液は排水窓108から還流槽106に溢水し、水タンク1内のフイルター2内に回収される。水タンク1内に回収された水は水噴射や水補給に使用される。
貯留室90内の海苔原料液が次工程に移送されて海苔原料液が下限になったことを検出スイッチ121が検出すると、その信号によって排出ポンプ34が再び作動して海苔原料液が貯留室90内に供給され、再び海苔原料液から小さな異物の除去作業が開始される。また、同時又は略同時に液供給手段31による供給室7への海苔原料液の供給が再開される。
【0031】
上記異物の除去作業が継続されて供給室7、排水室8内に異物が多く溜ったとき又は溜まる時点になると、作業員のスイッチ操作又はタイマーの作動により自動的に異物排出手段10が次のように作動する。
先ず、液供給手段31による供給室7内への海苔混合液の供給が停止される。液排出手段33の作動は継続されるので、排出ポンプ34の作動により供給室7内の海苔混合液が減少する。供給室7内の海苔混合液の液面が所定の高さ迄低下した時点をタイマー等(検出スイッチでも可)で検出すると、給水手段60の給水ポンプ61が所定時間例えば15秒間作動し、供給室7内に水を供給して海苔混合液の濃度を薄くすると共に海苔混合液の液面を高くする。この状態で液排出手段66が作動されて供給室7内の海苔混合液が排出室16に吸引されて異物除去作業が行われる。その結果、供給室7内の海苔混合液の量が少なくなると共にも海苔混合液に含まれる生海苔の量も少なくなる。
【0032】
その後、供給室7内の海苔混合液の量が少なくなり、液面が所定高さに迄減少したことを検出スイッチ120が検出すると、その信号により液排出手段33による海苔混合液の排出が停止されると共に水噴射手段66による水噴射が停止され、また異物排出手段10の異物排出ポンプ13が所定時間例えば10秒間(この時間は供給室7と排水室8内の液を排出するに必要な時間に設定すれば良い)作動し、供給室7と排水室8内の異物入り海苔混合液と異物入り水を水タンク1内のフイルター2内に供給する。フイルター2内に供給された海苔混合液の水は水タンク1内に回収される。なお、供給室7と排水室8内の異物入り海苔混合液や水は水タンク1に回収することなく廃却しても良い。
また、上記異物除去作業が継続されて貯留室90、排水室91内に異物が多く溜ったときには、貯留室90の海苔原料液を排出した後、図示しない排出管のバルブを開いて貯留室90、排水室91内の異物を外部に排出する。
上記のようにして供給室7と排水室8内の異物入り海苔混合液を排出する場合、仕切壁6の上縁に沿って全周又は一部に放水管を配設しておき、この放水管に仕切壁6の外面と内面に向かう噴射孔を多数開けておき、これらの噴射孔から水を噴射して仕切壁の内外面に付着している異物を流し落すようにすると仕切壁6の内外面をきれいに清掃できて好ましい。この放水管への水供給は異物排出手段10に連動して作動する供給ポンプによって行なうと便利である。
【0033】
なお、給水手段60によって水を補給して供給室7内の海苔混合液の生海苔の濃度を薄くする代わりに、水噴射手段66による水噴射の水量を増やしたり、或いは、水噴射手段66による水噴射を継続した状態で液排出手段33の作動を一時中断して海苔混合液の濃度を薄くしても良い。
【0034】
【発明の効果】
以上のように本発明では、供給室内に残される異物入り海苔混合液を所定の設定時間毎に自動的に排出するものであって、その供給室内に溜まった異物入り海苔混合液を排出するに先立ち、供給室内の海苔混合液を排出室に流す作業を継続した状態で、供給室内への海苔混合液の供給を所定時間停止し、供給室内の海苔混合液の液面が所定の高さ迄低下した時点を検出したとき、供給室内に水を所定時間供給することによって海苔混合液の濃度を薄くし、その後、供給室内の海苔混合液の液面が所定の高さ迄低下したことを検出したとき、供給室内の海苔混合液を排出室に流す作業を停止すると共に供給室内の異物入り海苔混合液を所定時間排出し、供給室内に残される海苔混合液の生海苔の量を少なくして異物入り海苔混合液を自動排出するので、供給室内の異物入り海苔混合液を排出する際にその海苔混合液に含まれる生海苔を少なくできて経済的であり、また供給室内の異物入り海苔混合液を短時間に自動排出でき、異物排出のための異物除去装置の停止時間を短くできて装置の稼働率を高くできると共に省力化を図ることができる。しかも、本発明では、供給室内の海苔混合液の量を少なくした後水を供給して供給室内の海苔混合液の生海苔の濃度を薄くしているので、海苔混合液の濃度を短時間に薄くでき、その結果異物排出に要する時間をより短くでき、また、本発明では、供給室内の海苔混合液の濃度を薄くすると共に供給室内の海苔混合液を少なくした後異物入り海苔混合液を排出するので、供給室内の海苔混合液を短時間に排出できると共に排出する海苔混合液内の生海苔の量をきわめて少なくできる。
【0035】
また本発明では、供給室内への海苔混合液の供給を停止した後供給室内に水を供給して濃度を薄くし、供給室内の海苔混合液の量が少なくなったとき供給室内の海苔混合液の排出作業を停止した後供給室内の異物入り海苔混合液を排出するので、異物除去装置の作動手段を利用して効率良く異物を排出でき、異物除去装置の性能を良くできる。また、本発明では、供給室に水を供給する給水手段を設け、供給室の底部に異物入り海苔混合液を排出可能な異物排出ポンプの吸引口を連結して供給室から異物入り海苔混合液を排出可能な異物排出手段を設け、異物排出手段の異物排出ポンプが所定時間毎に作動する作動時間を制御するタイマを備え、異物排出手段の作動に先立し、液排出手段が供給室内の海苔混合液を排出室に流す作業を継続した状態で、液供給手段による供給を停止し、供給室内の海苔混合液の液面が所定の高さ迄低下したとき、給水手段による水供給を所定時間行い、その後供給室内の海苔混合液の液面が所定の高さ迄低下したことを検出したとき、液排出手段による海苔混合液の排出を停止すると共に異物排出手段の異物排出ポンプを所定時間作動させて異物を排出するように制御する制御装置を備え、所定の設定時間毎に供給室内の海苔混合液の生海苔量を少なくして異物入り海苔混合液を自動排出するようにしているので、簡易な装置で安価に実施できる実用上の効果を発揮する。

When the supply of the laver raw material liquid to the storage chamber 90 is stopped and the lower limit of the liquid level is detected, the pumping pump 95 for pumping is stopped to stop the pumping of the laver raw material liquid.
[0023]
The above-mentioned seaweed foreign matter removing device is used in the laver production process between the raw algae washing process and the washing raw algae cutting process, between the raw algae rough cutting process and the raw algae fine cutting process, the original algae cutting washing process and the laver cutting washing dehydration It is used by being incorporated between the processes, between the laver cutting and washing dehydration process and the laver ripening dehydration process, between the laver ripening dehydration process and the laver blending process, or between the laver blending process and the laver making process.
In use, in the foreign matter removal unit A, the nori raw material liquid is supplied to the supply chamber 7 from the previous step by the liquid supply means 31 with an appropriate amount of water supplied to the water tank 1 and the storage tank 3 in advance. Part of the raw nori and part of the water in the nori mixed liquid in the supply chamber 7 enter the discharge chamber 16 through the separation hole 28, and foreign matter such as water of the nori raw material liquid and small nori swarf is connected to the communication hole 6 a of the partition wall 6. Through the drainage chamber 8. The supply of the laver raw material liquid into the supply chamber 7 is performed by intermittent operation of the supply pump of the supply means 31 for a predetermined time set in advance by a timer or the like. On the other hand, an appropriate amount, for example, about 80% of water is supplied to the storage tank 88 of the finishing unit B.
[0024]
In this state, the drive motor 44 of the liquid discharge means 33 and the pair of discharge pumps 34 and the supply pumps 74 and 75 of the water injection means 66 are operated, and the drive motor 80 is operated to rotate the injection nozzle 71 in the arrow direction. The operation of the discharge pump 34 is repeated for a necessary time, for example, one cycle of intermittently operating for 3 seconds and then stopping for 3 seconds. Accordingly, the laver mixture in the discharge chamber 16 is forcibly sucked intermittently every 3 seconds for 3 seconds. Further, the rotary valve body 42 is rotated by the operation of the drive motor 44, and the suction port of the discharge pump 34 is alternately communicated with the pair of discharge holes 29a, for example, every other second. When the laver raw material liquid in the discharge chamber 16 is forcibly and intermittently sucked alternately from the pair of discharge holes 29a, the laver raw material liquid in the supply chamber 7 is intermittently forcibly sucked into the discharge chamber 16 from the separation hole 28. At the same time, the suction force is changed, raw seaweed and water flow into the discharge chamber 16 from the separation hole 28, and foreign matter larger than the gap of the separation hole 28 is retained in the separation hole 28 and left in the supply chamber 7.
[0025]
The laver mixture sucked by the discharge pump 34 is supplied to the storage chamber 90 of the finishing unit B through the hose 54, the perspective connection pipe 57, the hose 59, and the like. When the supply pumps 74 and 75 of the water injection means 66 are operated, the water in the water tank 1 is sucked and supplied from the rotary shaft 70 to each injection nozzle 71, and water is continuously supplied from the injection holes of the injection nozzle 71. Spray. Since the spray nozzle 71 rotates with respect to the separation wall 27, spray water is periodically sprayed continuously into each separation hole 28, and as a result, raw laver and foreign matter clogged in the separation hole 28 are separated. The separation hole 28 is ejected from the hole 28 into the supply chamber 7 and the separation hole 28 is continuously and completely opened, so that fresh raw laver efficiently flows into the discharge chamber 8 from the separation hole 28. Further, high-pressure jet water is jetted into the supply chamber 7 from the separation hole 28, and the nori raw material liquid in the supply chamber 7 is subjected to impact force by the high-pressure jet water, and as a result, raw nori of the nori raw material liquid is jetted. The surface is washed cleanly by being struck by water, and foreign substances such as shrimp that have bitten into the surface of the raw nori are removed from the raw nori.
[0026]
Since the separation hole 28 is provided in an elongated shape having a hole width slightly larger than the thickness of the raw nori, the raw nori of the nori raw material liquid flows into the discharge chamber 16 from the separation hole 28 together with water. Foreign matter such as shrimp and small shellfish having a size larger than the hole width of the hole 28 is retained by the edge of the separation hole 28 and remains in the supply chamber 7. Since the width of the separation hole 28 is formed to be slightly larger than the thickness of the raw nori, for example, about 0.4 mm, the nori raw material liquid that has entered the discharge chamber 16 has, for example, about 0.4 mm or more. There is no foreign matter at all.
The nori raw material liquid in the supply chamber 7 is positively sucked into the discharge chamber 16 from the separation hole 28, so that fresh laver adheres to the outer periphery of the separation wall 27 and closes the separation hole 28. Since water is continuously sprayed from the spray hole of the spray nozzle 71 to the entire circumference of the separation wall 27 and the suction force acting on the discharge chamber 16 is intermittently stopped, it is adsorbed on the separation wall 27. The raw seaweed and foreign matter are surely separated by the high-pressure water jet from the spray nozzle 71 and diffused into the supply chamber 7, and the clogging of the separation hole 28 is completely eliminated, so that the flow of raw seaweed becomes extremely good. This greatly improves the ability to remove the laver foreign matter per unit time.
[0027]
Further, since the capacity of the supply pumps 74 and 75 of the water injection means 66 is made larger than the capacity of the discharge pump 34 of the discharge means 33, supply is possible even when the discharge pump 34 is sucking the laver raw material liquid in the discharge chamber 16. The amount of the seaweed raw material liquid in the chamber 7 increases. However, water and small foreign substances in the seaweed raw material liquid in the supply chamber 7 exit from the communication hole 6a of the partition wall 6 to the drainage chamber 8, and bubbles and light dust overflow with the water from the drainage window 107 into the reflux tank 106. Therefore, a large amount of water and small foreign matter in the supply chamber 7 flows from the communication hole 6a to the drain chamber 8 (water is circulated). As a result, small foreign substances are efficiently removed from the laver raw material liquid in the supply chamber 7, and light foreign substances such as shrimp in the nori raw liquid in the supply chamber 7 adhere to the inner peripheral surface of the partition wall 6 and are separated and removed. Is done. The water containing foreign matter collected in the reflux tank 106 is supplied to the filter 2 in the water tank 1 through the hoses 111 and 113 by the reflux pump 112, and clean water is collected in the water tank 1.
[0028]
When the nori raw material liquid in the discharge chamber 16 is sucked by the discharge pump 34, the concentration of the nori raw material liquid in the supply chamber 7 decreases, so that the liquid is interlocked with or substantially interlocked with the suction discharge by the discharge pump 34. The nori raw material liquid is supplied to the supply chamber 7 by the supply means 31. The reflux pump 112 automatically recovers the water in the reflux tank 106 into the water tank 1 based on a detection switch (not shown). Since the water is recovered from the reflux tank 106 in this way, It is economical because the water tank 1 can be replenished with a large amount of water when discharged, and the amount of water used can be saved.
[0029]
Next, in the finishing unit B, when the detection switch 121 detects that the liquid level in the storage chamber 90 has reached the upper limit, the operation of the discharge pump 34 of the liquid discharge means 33 is stopped. In this case, since the height of the overflow plate 108a of the drainage window 108 is set to be slightly lower than the upper limit height of the detection switch 121, when the concentration of the laver raw material liquid in the storage chamber 90 is low, the separation container Since water and small foreign matter flow out from the small holes 89a of the 70 and overflow from the drainage window 108, the water level in the storage chamber 90 does not rise, so the upper limit is not detected.
However, as the concentration increases, water and small foreign matter are less likely to flow out from the small holes 89a, the water level in the storage chamber 90 increases, the upper limit is detected, and the supply of the laver raw material liquid by the discharge pump 34 is stopped. At the same time, the supply of the laver raw material liquid to the supply chamber 7 by the liquid supply means 31 is stopped. In the storage chamber 90, the drive motor 105 is always driven to alternately rotate the agitating blade 102 forward and backward. The stirring blade 102 repeats normal rotation and reverse rotation every predetermined time, whereby the laver raw material liquid is agitated to separate small foreign matter adhering to the raw nori, and the separated small foreign matter enters the drain chamber 91 from the small hole 89a. Extruded.
[0030]
By stirring the nori raw material liquid in the storage chamber 90 for a predetermined time, for example, about 5 minutes (this time is arbitrary and not specified), small foreign matters mixed in the nori raw liquid are stored. The fresh seaweed from which the foreign matter has been removed and the water of good quality are left in the storage chamber 90. Thereafter, the feed pump 95 is operated to transfer the nori raw material liquid in the storage chamber 90 to the next process through the bent discharge pipe 93 and the hose 94, and this nori raw material liquid is used for nori making. The seaweed raw material liquid in the drainage chamber 91 that is drawn out of the storage chamber 90 overflows from the drainage window 108 to the reflux tank 106 and is collected in the filter 2 in the water tank 1. The water collected in the water tank 1 is used for water injection and water supply.
When the detection switch 121 detects that the nori raw material liquid in the storage chamber 90 is transferred to the next process and the nori raw material liquid reaches the lower limit, the discharge pump 34 is actuated again by the signal, and the nori raw material liquid is stored in the storage chamber 90. The small foreign matter is removed from the laver raw material liquid again. Further, the supply of the laver raw material liquid to the supply chamber 7 by the liquid supply means 31 is resumed simultaneously or substantially simultaneously.
[0031]
When the foreign matter removal operation is continued and a large amount of foreign matter is accumulated in the supply chamber 7 and the drain chamber 8, or when the foreign matter is accumulated, the foreign matter discharging means 10 is automatically activated by the operator's switch operation or timer operation. Operates as follows.
First, the supply of the laver mixture into the supply chamber 7 by the liquid supply means 31 is stopped. Since the operation of the liquid discharge means 33 is continued, the laver mixture in the supply chamber 7 is reduced by the operation of the discharge pump 34. When the time point when the level of the laver mixture in the supply chamber 7 is lowered to a predetermined height is detected by a timer or the like (it can be a detection switch), the water supply pump 61 of the water supply means 60 is operated for a predetermined time, for example, 15 seconds, and supplied. Water is supplied into the chamber 7 to reduce the concentration of the laver mixture and increase the level of the laver mixture. In this state, the liquid discharge means 66 is operated, the laver mixed liquid in the supply chamber 7 is sucked into the discharge chamber 16, and the foreign matter removing operation is performed. As a result, the amount of the laver mixture in the supply chamber 7 is reduced, and the amount of fresh laver contained in the laver mixture is also reduced.
[0032]
Thereafter, when the detection switch 120 detects that the amount of the laver mixture in the supply chamber 7 is reduced and the liquid level has decreased to a predetermined height, the discharge of the laver mixture by the liquid discharge means 33 is stopped by the signal. At the same time, water injection by the water injection means 66 is stopped, and the foreign matter discharge pump 13 of the foreign matter discharge means 10 is required for a predetermined time, for example, 10 seconds (this time is necessary for discharging the liquid in the supply chamber 7 and the drain chamber 8). It is sufficient to set the time) to supply foreign matter-containing laver mixed liquid and foreign matter-containing water in the supply chamber 7 and the drainage chamber 8 into the filter 2 in the water tank 1. The water of the laver mixture supplied in the filter 2 is collected in the water tank 1. The laver mixed liquid and water containing foreign matter in the supply chamber 7 and the drain chamber 8 may be discarded without being collected in the water tank 1.
Further, when the foreign matter removing operation is continued and a large amount of foreign matter is accumulated in the storage chamber 90 and the drain chamber 91, the laver raw material liquid in the storage chamber 90 is discharged, and then a valve of a discharge pipe (not shown) is opened to store the storage chamber 90. The foreign matter in the drain chamber 91 is discharged to the outside.
When discharging the mixed laver containing foreign matter in the supply chamber 7 and the drainage chamber 8 as described above, a water discharge pipe is provided on the entire periphery or part along the upper edge of the partition wall 6. If the water pipe has many injection holes directed to the outer surface and the inner surface of the partition wall 6 and water is sprayed from these injection holes so that the foreign matters adhering to the inner and outer surfaces of the partition wall are washed away, It is preferable because the inner and outer surfaces can be cleaned cleanly. It is convenient to supply the water to the water discharge pipe by a supply pump that operates in conjunction with the foreign matter discharging means 10.
[0033]
In addition, Instead of replenishing the water by the water supply means 60 and reducing the concentration of the raw nori in the mixed laver in the supply chamber 7, the amount of water jetted by the water jetting means 66 is increased, or the water jetting by the water jetting means 66 is performed. The operation of the liquid discharging means 33 may be temporarily interrupted in a state in which the seaweed is continued to reduce the concentration of the laver mixture.
[0034]
【The invention's effect】
As described above, in the present invention, Foreign matter-containing laver mixed liquid left in the supply chamber is automatically discharged at predetermined set times. Foreign matter collected in the supply chamber Nori mixed liquid Prior to discharging the laver mixture, supply the laver mixture to the supply chamber while continuing to flow the laver mixture in the supply chamber to the discharge chamber. Predetermined time Stop, When it detects the time when the liquid level of the laver mixture in the supply chamber drops to a predetermined height, Water in the supply chamber Predetermined time Supply Of the seaweed mixture by Reduce the concentration, then When it is detected that the level of the laver mixture in the supply chamber has dropped to the specified height, Stops flowing the laver mixture in the supply chamber to the discharge chamber As well as Foreign matter mixed laver mixed in the supply chamber Predetermined time Discharge And reducing the amount of raw nori in the nori mixture left in the supply chamber to automatically discharge the nori mixture with foreign matter Therefore, when discharging the nori mixed liquid containing foreign matter in the supply chamber, it is economical to reduce the raw nori contained in the nori mixed solution, and can automatically discharge the nori mixed liquid containing foreign matter in the supply chamber in a short time, The stop time of the foreign substance removing apparatus for discharging foreign substances can be shortened, the operating rate of the apparatus can be increased, and labor can be saved. In addition, in the present invention, the concentration of the nori mixture in the supply chamber is reduced by reducing the amount of the nori mixture in the supply chamber to reduce the concentration of the raw nori in the nori mixture in the supply chamber. As a result, the time required for discharging foreign matter can be shortened, and in the present invention, the concentration of the laver mixture in the supply chamber is reduced and the laver mixture in the supply chamber is reduced, and then the nori mixture containing foreign matter is discharged. Therefore, the laver mixture in the supply chamber can be discharged in a short time, and the amount of raw laver in the discharged laver mixture can be extremely reduced.
[0035]
Further, in the present invention, after the supply of the laver mixture into the supply chamber is stopped, water is supplied into the supply chamber to reduce the concentration, and when the amount of the laver mixture in the supply chamber decreases, the laver mixture in the supply chamber is reduced. Since the laver mixed liquid containing foreign matters in the supply chamber is discharged after the discharge operation is stopped, foreign matters can be efficiently discharged using the operating means of the foreign matter removing device, and the performance of the foreign matter removing device can be improved. In the present invention, water is supplied to the supply chamber. Water supply means And connect the suction port of the foreign matter discharge pump that can discharge the laver mixture containing foreign matter to the bottom of the supply chamber. A foreign matter discharge means that can discharge the laver mixed liquid containing foreign matter from the supply chamber is provided, and a timer that controls the operation time of the foreign matter discharge pump of the foreign matter discharge means every predetermined time is provided, prior to the operation of the foreign matter discharge means. In a state where the liquid discharge means continues the operation of flowing the laver mixed liquid in the supply chamber to the discharge chamber, Stop supply by liquid supply means When the liquid level of the laver mixture in the supply chamber drops to a predetermined height, water supply by the water supply means is performed for a predetermined time, and then the liquid level of the laver mixture in the supply chamber decreases to a predetermined height. Is detected, the discharge of the laver mixed liquid by the liquid discharge means is stopped and the foreign matter discharge pump of the foreign matter discharge means is operated for a predetermined time. It has a control device that controls to discharge foreign matter, Reduce the amount of raw nori in the nori mixture in the supply chamber every predetermined set time and automatically discharge the nori mixture with foreign objects. Therefore, a practical effect that can be implemented at low cost with a simple device is exhibited.
