Description

【0001】
【発明の属する技術分野】
この発明は、計量ホッパーに関するもので、主としてマダイ、ハマチ、ヒラメ等の魚類や、その他ゴボー、ナガイモ、レンコン等の長もの野菜等の重量計量にも利用できる。
【0002】
【従来の技術】
ウエイトサイザー形態の選別装置が一搬的に知られているが、この形態ではマダイやハマチ等は、所定の大きさの皿形容器に載せた状態で計量する。この計量後は選別箇所へ搬送させて、容器を転倒させて被計量物を選別排出させる。
【0003】
【発明が解決しようとする課題】
容器を反転させたり横側へ傾斜させて被計量物を選別位置等へ排出させる技術では、比較的大きく長い被計量物、例えば、マダイやハマチ等の魚類や、ゴボウや大根、レンコン等の長もの根菜類等では、これらを載せる容器が長く大きい特殊な形態となるため、装置が大型化となる。又、これら被計量物を容器上面から排出完了されるまでの長い時間を要し、大きい落差を要する等により、正確な計量や選別排出等が行われ難い。特にマダイ等の魚類を生きたままの状態で計量する場合は、衝撃や損傷を与えないようにすることはもとより、迅速で簡単な計量操作とすることが必要である。又、マダイのような扁平な魚では、魚体を横向きにすると計量中に跳ね上るように動いて正確な計量を行い難い。
【0004】
【課題を解決するための手段】
請求項1に記載の発明は、方形状のホッパー1の長手側両端の支架部2,3を支持部材4,5に支架させて、この支架部2,3の重量を各々計量可能に設け、底部の排出口6には開閉可能のシャッター7を設けたことを特徴とする計量ホッパーの構成とする。シャッター7を閉めたホッパー1に被計量物を長手方向に沿わせた状態に収容させる。この被計量物を収容したホッパー1の長手側両端の支架部2,3が支持部材4,5との間の計量器によって重量計量される。これらホッパー1の両支架部2,3の合計重量により被計量物の重量が演算される。計量後はシャッター7を開いて被計量物を底部の排出口6から落下排出させる。このときシャッター7の排出口6開きによって被計量物は全長にわたって同時に速かに排出される。
【0005】
請求項2に記載の発明は、前記ホッパー1は、上端部をテーパー状に開拡する漏斗部8と、この漏斗部8の下部にあって前後に狭く所定高さに垂直状に形成される規制室部9とからなることを特徴とするものである。この規制室部9の高さや幅等の形態は被計量物である対象物に応じて設定されるが、前記のようにホッパー1に供給した被計量物は、上部の漏斗部8内を案内されて、下部の幅狭く所定高さの規制室部9に供給され、長い被計量物の両腹部が挾持されるような形態に支持案内される。
【0006】
請求項3に記載の発明は、前記シャッター7は、支架部2,3の計量に基づいて連動して開かれることを特徴とするものである。前記のようにホッパー1内に供給されて重量を計量される被計量物は、この両側の支架部2,3での計量が行われた後ち、この計量に基づいて直接、又は間接に連動してシャタ7が開かれて彼計量物がこの排出口6から排出される。
【0007】
請求項4に記載の発明は、前記ホッパー1は、被計量物を受けた状態で搬送されながら計量されると共に、このシャッター7は、ホッパー1の上下動に基づいて、計量搬送行程では閉鎖ロックし、選別排出行程ではロック解除して開放することを特徴とするものである。ホッパー1が上動位置で計量搬送される間は、このホッパー1の上動によりシャッター7が閉鎖位置にロックされて開かない状態にある。この計量後の選別排出行程では、ホッパー7が下動されて、この下動によって、閉鎖位置にロックされていたシャッター7がロック解除されて排出口6を開放状態とする。被計量物を所定の選別位置へ搬送してこの排出口6から排出させることができ選別装置を兼ねた形態とする。
【0008】
【発明の効果】
請求項1に記載の発明は、長もの被計量物を長手方向に沿わせるようにしてホッパー1内に供給収容させて、このホッパー1の長手方向の両端支架部2,3の重量を計量するものであるから、頭尾部乃至左右で重量の異なる長もの被選別物を安定した姿勢に支持させて、正確な計量を行うことができる。このホッパー1内に供給されて計量された被計量物は、底部排出口6のシャッター7の開きによって、この排出口6から落下排出させるため、略計量されたままの姿勢で排出されて、速かに排出され、排出高さを低くできると共に、被計量物の引きずり等を少くして、排出位置への落下排出を正確に行わせることができる。
【0009】
請求項2に記載の発明は、特に生きている魚を被計量物とする場合に好適である。マダイのように扁平状の魚体では、腹部を下側にした姿勢で供給しても、漏斗部8のテーパー状傾斜面によって、この漏斗部8から規制室部9内への滑り込みが円滑に行われて魚体に損傷を与え難く、この規制室部9内に入ると魚体の腹部が左右両側部から挾持案内されるようになり、魚の動きが少く、安定した計量を行わせることができる。しかも、この規制室部9は魚体の扁平面に沿うように適宜の高さを有するため、魚体を傷付けないように支持案内することができる。
【0010】
請求項3に記載の発明は、ホッパー1の両端支架部2,3における計量に基づいて自動的にシャッター7が開かれるため、生鮮魚等の計量処理を速かに行わせて、魚勢、鮮度等を長く維持できる。
【0011】
請求項4に記載の発明は、ホッパー1は被選別物を受けた状態で計量搬送行程を搬送されながら計量され、この被選別物を選別排出するもので、このホッパー1の上下動によってシャッター7の開閉や、このロック、及びロック解除を行うものであるから、計量中にシャッター7が開くようなことがなく、簡単な構成で正確な計量を行うことができ、このロックがホッパー1の上下動によって行われるため、ロック機構も簡単にすることができる。
【0012】
【発明の実施の形態】
この発明の実施例を図面に基づいて説明する。ホッパー1は、平面視で左右横方向に長く、前後方向には狭く形成した細長い長方形態とし、上部の漏斗部8と下部の規制室部9と底部のシャッター7とから構成され、規制室部9の底部には排出口6が形成されて、前側辺、又は後側辺に沿うシャッタ軸10の周りに上下回動自在にしてシャッター7が設けられる。漏斗部8は、上端側が前後に広くてテーパー状、乃至弧状曲面の漏斗面11を形成する。この下側の規制室部9は、該漏斗面11に連続する規制面12が上下垂直状に、かつ略平行状に形成されている。この規制室部9の長手方向の長さや、規制面12間の幅、及び上下方向の高さ等は、被計量物Aの大きさや、形体、種類等に応じた寸法に設定する。又、前記規制面12は、正確な平行面でなくても、規制室部9内側へ凸弧状曲面、又は逆に凹弧状曲面等に形成することもできる。
【0013】
図例のホッパー1の規制室部9は、被計量物Aである生きているマダイを計量するための形態として、魚体の大きに適合させるように、しかもマダイAは腹部Bを下側に向け背部Cを上側に向けた状態の泳ぎ姿勢にして収容する構成としている。このため、前後規制面12間の幅が比較的狭く形成され、高さ乃至深さの比較的大きい形態に形成される。このようなホッパー1に生きマダイAを泳ぎ姿勢にして収容させると、マダイは静かで暴れない状態となり、計量を正確に行うことができる。
【0014】
このようなホッパー1は、左右両側端の支架部2,3を支持部材4,5に支持させて、これら支持部材4,5に設けられるロードセル40,41からなる計量装置によって各々計量されるが、この計量構成の形態としては、ホッパー1を移送チエン13で牽引搬送しながら、この搬送中に被計量物Aの重量を計量して、この重量区分毎に選別排出させる計量選別装置の形態と、単に被計量物Aを受けて計量して、計量毎に排出、乃至ビニール袋57などの容器に収容させる計量形態とがある。
【0015】
このうち計量選別装置の形態の実施例を図1〜図7に基づいて説明する。前記ホッパー1を多数移送チエン13に沿って配置して回転移送させながら、このホッパー1の左右の支架部2,3は、支持部材4,5を一部に設けたガイドレール25に摺動支持させる。このホッパー1の搬送行程始端部の供給行程で被選別物Aを供給させ、続く計量行程では計量させ、更に続く選別行程では重量区分毎に選別排出させる構成とする。
【0016】
前記左右一対の移送チエン13は前後のスプロケット16,17間に張設されて、この左右一対の移送チエン13間にわたって、取付ブラケット14の左右両端部を取付軸15部で回動自在にして取付ける。この取付ブラケット14は方形状の囲桁形態として、この左右両側面に取付軸15やスライダー18等が設けられる。この取付軸15は移送チエン13のチエンプレートに固定され、これら取付ブラケット14とスライダー18は一体として、この取付軸15の周わりに回動自在である。又、このスライダー18は、取付ブラケット14とは略直交形態に形成されて、取付軸15部の前側と後側とに回転自在のローラ19が設けられる。このローラ19を機枠20に取付けられた左右一対のガイドレール21上に摺動させて案内させることができる。このガイドレール21は移送チエン13の回転行程の主として上辺行程部に設けられて、取付ブラケット14を上下垂直状に維持させ、下辺行程部ではこの取付ブラケット14が移送チエン13に対して適宜傾斜角度を維持するように案内させる構成とすることもできるが、図例のように、この下辺行程部にはガイドレール21を構成しないで、自由な垂下姿勢で移送させる形態とすることができる。
【0017】
前記ホッパー1は、この取付ブラケット14の後側四隅部において平行状の連結リンク22を介して上下動自在に連結される。このホッパー1の左右両側には支架部2,3としてローラ23を回転自在にしたピン24を有し、このローラ23を機枠20の左右両側部に設けられる一対のガイドレール25上に摺動支持させて案内させる。このガイドレール25は、移送チエン13の上辺行程部に沿って設けられるが、下辺行程部には設けなくてもよい。又、このガイドレール25の始端部には、左右のロードセル40,41で支持されるレール形態の支持部材4,5が設けられて、該ホッパー1のローラ23を摺動支持することによって、各々ロードセル40,41で計量することができる。
【0018】
このガイドレール25の途中には、各重量選別区分位置に切替レール部26が配置されて、ガイドレール25上を摺動案内されるローラ23をこのガイドレール25の切替えによってこの切替口32を下側へ下降案内させて、ホッパー1を下動させることができる。この切替レール部26は後端を切替軸27の周りに上下回動自在に支持し、前端を上動位置ではガイドレール25上面に一致させ、切替口32を閉鎖する状態とし、下動位置では下向きに傾斜させて切替口32を開いてローラ23を下動案内させる。この切替レール部26は下側に押上縁28を有して自重下回動でき、上動位置側へは前記ガイドレール21を案内されるスライダー18のローラ19通過によって、該押上縁28が押し上げられると共に、この上動位置でピン穴29に係合しうるソレノイドピン30が設けられる。このソレノイドピン30を、ソレノイド31の電磁作動でピン穴29から係合を外すことによって、切替レール部26が自重で下方へ回動される。そして、この状態でホッパー1のローラ23が上面を通過するとき、この切替レール部26の下動された切替口32を下動させて切替案内される。この切替レール部26の上動復帰はスライダー18の移動を利用したが、復帰バネを設けて上動復帰させる構成とすることもできる。該支架部2,3のローラ23の下動位置を案内するガイドレール60が設けられている。
【0019】
前記ホッパー1の底部排出口6を開閉するシャッター7は、この排出口6の前側縁に沿って設けられるシャッタ軸10の周りに下方へ回動されることによって開放される。このホッパー1の左右両側部にはシャッター7の開閉を許す左右一対のロックレバー33がレバーピン34周りに回動自在に設けられる。このロックレバー33の後端にはフック35が形成されて、シャッター7の左右両側端で後端縁から突出されるシャッタピン36に下側から係合して、このシャッター7の閉鎖位置を維持できる。又、このロックレバー33の前端部38は、前記取付ブラケット14の取付軸15とこの下方の規制ピン37との間に位置させて、このロックレバー33の上下回動域を制限させる。さらに、このロックレバー33と前記ローラ23を有するピン24との間には規制ロッド39が連結される。この規制ロッド39の上部には長穴42を形成して、この長穴42を該ピン24に嵌合させて、この長穴42により規制ロッド39の上下動を規制することによっても、ロックレバー33の揺動域を規制している。
【0020】
このようなシャッター7の構成により、ホッパー1が切替レール部26の下向切替えによって下動され、このホッパー1と共に下動されるロックレバー33の前端部38が取付ブラケット14の規制ピン37に係止されて、フック35部の係合ロックが解除されて下側へ重力回動されるため、これに支持されているシャッタピン36と一体のシャッター7がシャッタ軸10の周りに下方へ回動して排出口6が開放される。このロックレバー33のフック35とシャッタピン36との回動軌跡線は、各回動中心のレバーピン34とシャッタ軸10位置とが前後に偏位しているため、異なる円弧軌跡に描かれる。このためロックレバー33のフック35が回動しないかぎり、被計量物を受けたシャッター7は下方へ回動されず、排出口6は開かない。この状態で支架部2,3のローラ23が、ガイドレール25、及び支持部材4,5の上を摺動案内されている間は、このローラ23部でのみホッパー1部の重量を支持させて正確な計量を行わせるようにしている。ホッパー1が前記切替レール部26の切替えによって下降すると、ロックレバー33が規制ピン37に係止して回動され、フック35を退避回動させてシャッタピン36との係合を外して、シャッター7を開放回動させる。
【0021】
又、このシャッター7の閉鎖は、シャッタ軸10周りに上方回動されて行われる。このシャッター7の回動はホッパー1が移送チエン13の始端部側のスプロケット17周りに回動されるとき、このスプロケット軸42周りに設けられるリング43に摺接させることにより、シャッター7を押上げて回動させ、この排出口6を閉鎖させる。この閉鎖位置ではホッパー1がリンク22を介して平行状態を維持して上動されるため、ロックレバー33及び規制ロッド39が自重回動され、乃至は前端部38が取付軸15部に接当して回動されて、フック35が閉鎖位置のシャッタピン36を係合支持して開口しないようにロックする。
【0022】
このようなホッパー1の回転移動行程の始端部上には供給台44や、案内板45が設けられ、この間に供給口46が形成されて、供給台44上の被計量物Aを各箇毎に供給口46から下側を移動される各ホッパー1内へ供給することができる。47は各選別区分域のシャッター7開放位置の直下に設けられたシャーターで、シートを波形状に形成して、左右一側へ傾斜させて、排出口6から選別落下される被選別物Aを受けて滑落させる。48はモータで、スプロケット16の軸49との間にベルト乃至チエン50を掛けわたして回転駆動する。
【0023】
前記左右一対のロードセル40,41によってホッパー1の左右支架部2,3の重量を計量すると、各計量値がコントローラ51へ入力されて演算され、被計量物Aの重量が算出されて計量表示52部にデジタル表示されると共に、この選別位置のソレノイド31が出力されて、切替レール部26のピン穴29からソレノイドピン30が外される。又、このときソレノイドピン30が外されて一定時間が経過すると後続して移動されるホッパー1のスライダー18によって復帰される。
【0024】
モータ48によって移送チエン13を回転するとこの取付ブラケット14によってホッパー1が牽引移動される。この上辺部の移動行程ではスライダー18がガイドレール21上面に案内されるため取付ブラケット14は略垂直状態を維持され(図3、図4)、従ってホッパー1もこれと平行状に維持される。又、下辺部の移動行程ではスライダー18がガイドレール21から外れた状態にあるために、取付ブラケット14を傾斜させた状態にして、ホッパー1は重力で垂下される(図3、図6)。このホッパー1が始端部のスプロケット17部の周りを上側へ回動されるとき、スライダー18がガイドレール21の始端部に案内される。又、支架部2,3のローラ23がガイドレール25の始端部に案内される。そしてホッパー1のシャッター7の下面をスプロケット軸42上のリンク43の外周に受けさせるため、このシャッター7が排出口6を閉鎖すると共に、ホッパー1の姿勢は図6から図4の状態に順次移行される。
【0025】
このようにしてホッパー1が始端部に達して供給口46の下側に位置すると、供給台44上の被計量物Aを一箇宛て供給口46からホッパー1内へ供給する。このときシャッター7はフック35に係止されているため、被計量物Aを受けても開かない。この状態のホッパー1は殆どローラ23部を介してガイドレール25上に支持された状態にある。そして、このローラ23がガイドレール25の途中の支持部材4,5上を通過するとき、各ロードセル40,41による計量を受ける。これらホッパー1の左右両側部の計量に基づいて、コントローラ51からのソレノイド31出力によりこのホッパー1の通る選別位置の切替レール部26からソレノイドピン30が抜き外されて、下動状態にある。ここにホッパー1のローラ23がこの切替口32を下動案内されて、ホッパー1は連結リンク22を介して平行状に下動される。この下動に伴ってロックレバー33がレバーピン34周りに回動されて、シャッタピン36の係止を外して、シャッター7を下方回動させて排出口6を開く(図5)、この排出口6から被計量物Aが落下されてシュータ47に受けられる。
【0026】
このような計量選別作用におい、ホッパー1内に収容される被計量物Aが生きているマダイのように体形の比較的扁平状の形態である場合は、このマダイAの腹部Bを下側のシャッター7面に受けさせて背部Cを上方に向けた状態として供給する。このとき左右両側の側部Dは前後の規制面12に支持されて、あたかも泳ぎ姿勢と同様になり、マダイAは静かな姿勢を維持することができ、このため計量作用が安定し正確に行われる。
【0027】
次に、主として図8、図9に基づいて上例と異なる点を説明する。ホッパー1は単に計量を行う計量装置の形態としたものである。このホッパー1は計量フレーム53の上部に支持され、この支持部材4,5には角軸状の支架部2,3が嵌合支持されて、ホッパー1が前後に傾斜しないよう垂直姿勢を維持している。シャッター7を開閉するソレノイド31はホッパー31の外側面に取付けられて、通電によって閉鎖させ、非通電によってバネ54により開放するように作動される。
【0028】
計量フレーム53の底部には受台55がバネ56等の緩衝部材を介して支持されて、衝撃を緩和しうる。この受台55上には容器乃至ビニール袋57を載置して、排出口6から落下されるマダイAを直接受けて収容することができる。58はゴム製等からなる供給ガイドで、上側に排出口6をのぞませて計量フレーム53上部に取付けられる。
【0029】
マダイAを一尾毎ホッパー1に供給して計量すると、この計量によってソレノイド31によりシャッター7が一定時間開かれて、マダイAが排出口6からビニール袋57内に落下供給される。このビニール袋57には酸素を注入してマダイAを生きた状態に維持させて、取扱い、乃至運搬することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a weighing hopper, and can be mainly used for weighing fish such as red sea bream, hamachi and flounder, and other long vegetables such as gobo, yam and lotus root.
[0002]
[Prior art]
A sorter in the form of a weight sizer is known in a portable manner. In this embodiment, red sea bream, hamachi, and the like are weighed in a state of being placed in a dish-shaped container having a predetermined size. After the weighing, the weighing object is transported to a sorting place, the container is turned over, and the objects to be weighed are selectively discharged.
[0003]
[Problems to be solved by the invention]
In the technology of discharging a weighing object to a sorting position by inverting or tilting the container to the side, a relatively large and long weighing object, for example, fish such as red sea bream and yellowtail, burdock, radish, and lotus root, etc. In the case of root vegetables and the like, the container in which they are placed takes a long and special form, so that the apparatus becomes large. In addition, it takes a long time until the objects to be weighed are completely discharged from the upper surface of the container, and a large head is required. Therefore, accurate weighing, sorting and discharging are difficult to be performed. In particular, when weighing fish such as red sea bream in a living state, it is necessary not only to prevent impact and damage but also to perform a quick and simple weighing operation. Further, in a flat fish such as a red sea bream, if the fish body is turned sideways, it moves so as to jump up during weighing, and it is difficult to perform accurate weighing.
[0004]
[Means for Solving the Problems]
According to the first aspect of the present invention, the supporting portions 2, 3 at both ends on the longitudinal side of the rectangular hopper 1 are supported on the supporting members 4, 5, and the weights of the supporting portions 2, 3 are provided so as to be weighable, A discharge hopper 6 at the bottom is provided with a shutter 7 that can be opened and closed to form a weighing hopper. The object to be weighed is accommodated in the hopper 1 with the shutter 7 closed in a state of extending along the longitudinal direction. The supporting portions 2 and 3 at both ends on the longitudinal side of the hopper 1 containing the object to be weighed are weighed by a weighing device between the supporting members 4 and 5. The weight of the object to be weighed is calculated from the total weight of the two supporting portions 2 and 3 of the hopper 1. After the weighing, the shutter 7 is opened to drop the object to be weighed from the outlet 6 at the bottom. At this time, the object to be weighed is simultaneously discharged quickly over the entire length by opening the discharge port 6 of the shutter 7.
[0005]
According to the second aspect of the present invention, the hopper 1 is formed in a funnel portion 8 whose upper end portion is tapered and expanded, and is formed vertically below a predetermined height at a lower portion of the funnel portion 8. It is characterized by comprising a regulation room 9. The form such as the height and width of the regulation chamber 9 is set according to the object to be weighed, but the object to be weighed supplied to the hopper 1 as described above is guided in the upper funnel 8. Then, it is supplied to the narrow, predetermined height regulating chamber 9 at the lower portion, and is supported and guided in such a form that both abdominal parts of the long object to be weighed are clamped.
[0006]
The invention according to claim 3 is characterized in that the shutter 7 is opened in conjunction with the measurement based on the measurement of the supporting portions 2 and 3. The object to be weighed, which is supplied into the hopper 1 and weighed as described above, is directly or indirectly linked based on the weighing after the weighing is performed on the supporting portions 2 and 3 on both sides. Then, the shutter 7 is opened and the weighed material is discharged from the discharge port 6.
[0007]
According to a fourth aspect of the present invention, the hopper 1 is weighed while being conveyed while receiving an object to be weighed, and the shutter 7 is closed and locked in the weighing and conveying stroke based on the vertical movement of the hopper 1. In the sorting and discharging process, the lock is released and released. While the hopper 1 is weighed and conveyed at the upward movement position, the shutter 7 is locked at the closed position by the upward movement of the hopper 1 and cannot be opened. In the sorting and discharging process after the weighing, the hopper 7 is moved down, and by this moving down, the shutter 7 locked in the closed position is unlocked and the outlet 6 is opened. The object to be weighed is conveyed to a predetermined sorting position and can be discharged from the discharge port 6 so as to serve also as a sorting device.
[0008]
【The invention's effect】
According to the first aspect of the present invention, a long object to be weighed is supplied and accommodated in the hopper 1 along the longitudinal direction, and the weight of the both-end support portions 2 and 3 in the longitudinal direction of the hopper 1 is weighed. As a result, it is possible to support a long object to be sorted having different weights at the head and tail or right and left in a stable posture and perform accurate weighing. The object to be weighed supplied and weighed into the hopper 1 is dropped and discharged from the discharge port 6 by opening the shutter 7 of the bottom discharge port 6, so that the object is discharged in a substantially weighed posture, and quickly discharged. Crate is discharged, the discharge height can be reduced, the drag of the object to be weighed is reduced, and the discharge to the discharge position can be performed accurately.
[0009]
The invention described in claim 2 is particularly suitable when a living fish is to be weighed. In a flat fish body such as a red sea bream, even if the fish is supplied with its abdomen down, the tapered slope of the funnel 8 allows the funnel 8 to smoothly slide into the regulation chamber 9. The fish body is hardly damaged, and when entering the regulation chamber 9, the abdomen of the fish body is guided and pinched from both left and right sides, so that the movement of the fish is small and stable weighing can be performed. In addition, since the regulating chamber 9 has an appropriate height along the flat surface of the fish, it can support and guide the fish without damaging the fish.
[0010]
According to the third aspect of the present invention, since the shutter 7 is automatically opened based on the measurement at the both ends supporting portions 2 and 3 of the hopper 1, the measuring process of fresh fish or the like is performed quickly, Freshness etc. can be maintained for a long time.
[0011]
According to a fourth aspect of the present invention, the hopper 1 is weighed while being conveyed in a weighing / conveying process in a state in which the hopper 1 receives the material to be sorted, and sorts and discharges the material to be sorted. Since the shutter is opened and closed, and the lock and unlock are performed, the shutter 7 does not open during the weighing, and accurate weighing can be performed with a simple configuration. Since the operation is performed by movement, the lock mechanism can be simplified.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described with reference to the drawings. The hopper 1 has an elongated rectangular shape that is long in the left-right and lateral directions in plan view and narrow in the front-rear direction, and includes an upper funnel portion 8, a lower regulating chamber portion 9, and a bottom shutter 7, and a regulating chamber portion. A discharge port 6 is formed at the bottom of the shutter 9, and a shutter 7 is provided so as to be vertically rotatable around a shutter shaft 10 along the front side or the rear side. The funnel portion 8 forms a funnel surface 11 having a tapered or arcuate curved surface with the upper end side wide front and back. The lower regulating chamber 9 has a regulating surface 12 that is continuous with the funnel surface 11 and is formed vertically vertically and substantially parallel. The length of the regulation chamber 9 in the longitudinal direction, the width between the regulation surfaces 12, the height in the vertical direction, and the like are set to dimensions according to the size, shape, type, and the like of the object A to be weighed. Further, the regulating surface 12 may be formed as a curved surface convex toward the inside of the regulating chamber 9 or a concave curved surface, etc., instead of being an accurate parallel surface.
[0013]
The regulating chamber section 9 of the hopper 1 in the illustrated example is configured to measure a living red sea bream, which is the object A, so as to be adapted to the size of the fish body, and the red sea bream A has its abdomen B downward. It is configured that the back part C is accommodated in a swimming posture with the back part facing upward. For this reason, the width between the front and rear regulating surfaces 12 is formed to be relatively narrow, and the height to the depth is formed to be relatively large. When the live red sea bream A is accommodated in such a hopper 1 in a swimming posture, the red sea bream A is in a calm and non-violent state, and the weighing can be performed accurately.
[0014]
In such a hopper 1, the supporting portions 2, 3 on both left and right ends are supported by supporting members 4, 5, and the hopper 1 is weighed by a weighing device including load cells 40, 41 provided on these supporting members 4, 5. As a form of this weighing configuration, there is a form of a weighing and sorting device which weighs the object A to be weighed during the transfer while the hopper 1 is being conveyed by the transfer chain 13 and sorts and discharges the weighing object A for each weight division. There is a weighing mode in which the object A is simply received and weighed, discharged every time the weighing is performed, or stored in a container such as a plastic bag 57.
[0015]
An embodiment of the weighing and sorting device will be described with reference to FIGS. While the plurality of hoppers 1 are arranged along the transfer chain 13 and rotationally transferred, the left and right supports 2 and 3 of the hopper 1 are slidably supported by guide rails 25 provided with support members 4 and 5 in part. Let it. The object A to be sorted is supplied in a supply process at the start end of the transport process of the hopper 1, weighed in a subsequent weighing process, and sifted and discharged for each weight division in a further subsequent sorting process.
[0016]
The pair of left and right transfer chains 13 is stretched between the front and rear sprockets 16 and 17, and the right and left ends of the mounting bracket 14 are rotatably mounted on the mounting shaft 15 between the pair of right and left transfer chains 13. . The mounting bracket 14 is in the form of a square girder, and a mounting shaft 15 and a slider 18 are provided on both left and right side surfaces. The mounting shaft 15 is fixed to a chain plate of the transfer chain 13. The mounting bracket 14 and the slider 18 are integrally rotatable around the mounting shaft 15. The slider 18 is formed substantially orthogonal to the mounting bracket 14, and has rotatable rollers 19 on the front and rear sides of the mounting shaft 15. The roller 19 can be guided by sliding on a pair of left and right guide rails 21 attached to the machine frame 20. The guide rail 21 is provided mainly in the upper stroke portion of the rotation stroke of the transfer chain 13 to maintain the mounting bracket 14 vertically and vertically, and in the lower stroke portion, the mounting bracket 14 is appropriately inclined at an angle to the transfer chain 13. However, as shown in the figure, the guide rail 21 may not be provided in the lower stroke portion, and the guide may be transported in a free hanging posture.
[0017]
The hopper 1 is vertically movably connected via parallel connecting links 22 at four rear corners of the mounting bracket 14. On the left and right sides of the hopper 1, there are provided pins 24 for freely rotating rollers 23 as supporting portions 2 and 3, and the rollers 23 slide on a pair of guide rails 25 provided on both right and left sides of the machine frame 20. Let them be supported and guided. The guide rail 25 is provided along the upper stroke of the transfer chain 13, but need not be provided on the lower stroke. At the starting end of the guide rail 25, support members 4 and 5 in the form of rails supported by left and right load cells 40 and 41 are provided, and the rollers 23 of the hopper 1 are slidably supported. The weight can be measured by the load cells 40 and 41.
[0018]
In the middle of the guide rail 25, a switching rail portion 26 is arranged at each weight sorting section position, and the roller 23 slidably guided on the guide rail 25 lowers the switching port 32 by switching the guide rail 25. The hopper 1 can be moved downward by being guided downward to the side. The switching rail portion 26 supports a rear end of the switching shaft 27 so as to be rotatable up and down around a switching shaft 27, and has a front end aligned with the upper surface of the guide rail 25 in the upward movement position, closing the switching opening 32, and in the lower movement position. The switching port 32 is opened by inclining downward, and the roller 23 is guided to move downward. The switching rail portion 26 has a push-up edge 28 on the lower side and can be rotated under its own weight, and the push-up edge 28 is pushed up by the slider 18 guided by the guide rail 21 to the upper moving position side. And a solenoid pin 30 that can be engaged with the pin hole 29 in the upwardly moved position. When the solenoid pin 30 is disengaged from the pin hole 29 by the electromagnetic operation of the solenoid 31, the switching rail portion 26 is rotated downward by its own weight. Then, when the roller 23 of the hopper 1 passes through the upper surface in this state, the switching rail 32 is moved downward by moving the lower switching port 32 to be switched and guided. The upward movement return of the switching rail portion 26 utilizes the movement of the slider 18, but a return spring may be provided to perform the upward movement return. A guide rail 60 is provided for guiding the lower movement position of the rollers 23 of the support portions 2 and 3.
[0019]
The shutter 7 for opening and closing the bottom outlet 6 of the hopper 1 is opened by being rotated downward around a shutter shaft 10 provided along the front edge of the outlet 6. A pair of left and right lock levers 33 that allow the shutter 7 to open and close are provided on both left and right sides of the hopper 1 so as to be rotatable around lever pins 34. A hook 35 is formed at the rear end of the lock lever 33 and engages from below with a shutter pin 36 protruding from the rear edge at both left and right ends of the shutter 7 to maintain the closed position of the shutter 7. it can. The front end 38 of the lock lever 33 is positioned between the mounting shaft 15 of the mounting bracket 14 and the lower regulating pin 37 to limit the vertical rotation range of the lock lever 33. Further, a regulating rod 39 is connected between the lock lever 33 and the pin 24 having the roller 23. A lock hole is also formed by forming a long hole 42 on the upper part of the restriction rod 39, fitting the long hole 42 to the pin 24, and restricting the vertical movement of the restriction rod 39 by the long hole 42. 33 swing ranges are regulated.
[0020]
With such a configuration of the shutter 7, the hopper 1 is moved downward by the downward switching of the switching rail portion 26, and the front end 38 of the lock lever 33 that is moved downward together with the hopper 1 is engaged with the regulating pin 37 of the mounting bracket 14. Since the lock is stopped and the engagement lock of the hook 35 is released and the gravitational rotation is performed downward, the shutter 7 integrated with the shutter pin 36 supported by this is rotated downward around the shutter shaft 10. Then, the discharge port 6 is opened. The rotation trajectory line between the hook 35 of the lock lever 33 and the shutter pin 36 is drawn in a different arc trajectory because the lever pin 34 at the center of each rotation and the position of the shutter shaft 10 are deviated back and forth. Therefore, as long as the hook 35 of the lock lever 33 does not rotate, the shutter 7 that has received the object to be weighed is not rotated downward, and the discharge port 6 does not open. In this state, while the rollers 23 of the supports 2 and 3 are slid and guided on the guide rail 25 and the support members 4 and 5, the weight of one hopper is supported only by the rollers 23. We try to make accurate weighing. When the hopper 1 is lowered by the switching of the switching rail portion 26, the lock lever 33 is locked by the restriction pin 37 and is rotated, and the hook 35 is retracted and rotated to release the engagement with the shutter pin 36, and the shutter is released. 7 is opened and rotated.
[0021]
In addition, the shutter 7 is closed by being pivoted upward about the shutter shaft 10. When the hopper 1 is rotated around the sprocket 17 on the starting end side of the transfer chain 13, the shutter 7 is pushed up by slidingly contacting a ring 43 provided around the sprocket shaft 42. And the outlet 6 is closed. In this closed position, the hopper 1 is moved upward while maintaining the parallel state via the link 22, so that the lock lever 33 and the regulating rod 39 are rotated by their own weight, or the front end 38 is in contact with the mounting shaft 15. When the hook 35 is rotated, the hook 35 engages and supports the shutter pin 36 in the closed position and locks the shutter pin 36 so as not to open.
[0022]
A supply table 44 and a guide plate 45 are provided on the start end of the rotation movement process of the hopper 1, and a supply port 46 is formed between the supply table 44 and the guide plate 45 so that the object A on the supply table 44 can be individually Can be supplied from the supply port 46 into each hopper 1 to be moved downward. Reference numeral 47 denotes a shutter provided immediately below the shutter 7 opening position of each sorting section. The sheet is formed into a corrugated shape, inclined to one side to the left and right, and the sorting object A sorted and dropped from the discharge port 6 is removed. Receive and slide down. Reference numeral 48 denotes a motor, which is rotated by a belt or chain 50 between the sprocket 16 and the shaft 49.
[0023]
When the weight of the left and right support portions 2 and 3 of the hopper 1 is weighed by the pair of left and right load cells 40 and 41, the respective weighed values are input to the controller 51 and calculated, the weight of the object A is calculated and the weighing display 52 is displayed. And the solenoid 31 at this sorting position is output, and the solenoid pin 30 is removed from the pin hole 29 of the switching rail 26. At this time, after a certain time has elapsed since the solenoid pin 30 is removed, the slider 18 of the hopper 1 which is moved subsequently returns to the normal position.
[0024]
When the transfer chain 13 is rotated by the motor 48, the hopper 1 is pulled by the mounting bracket 14. During the movement of the upper side, the slider 18 is guided on the upper surface of the guide rail 21 so that the mounting bracket 14 is maintained in a substantially vertical state (FIGS. 3 and 4), so that the hopper 1 is also maintained in a parallel state. In addition, since the slider 18 is disengaged from the guide rail 21 during the lower stroke, the mounting bracket 14 is inclined and the hopper 1 is suspended by gravity (FIGS. 3 and 6). When the hopper 1 is rotated upward around the sprocket 17 at the start end, the slider 18 is guided by the start end of the guide rail 21. Further, the rollers 23 of the supports 2 and 3 are guided to the start end of the guide rail 25. The shutter 7 closes the discharge port 6 so that the lower surface of the shutter 7 of the hopper 1 is received on the outer periphery of the link 43 on the sprocket shaft 42, and the posture of the hopper 1 sequentially shifts from the state of FIG. 6 to the state of FIG. Is done.
[0025]
When the hopper 1 reaches the start end and is located below the supply port 46 in this way, the objects A on the supply table 44 are supplied to the hopper 1 from the supply port 46 by one. At this time, since the shutter 7 is locked by the hook 35, the shutter 7 does not open even when the object A is received. The hopper 1 in this state is almost supported on the guide rail 25 via the roller 23. When the roller 23 passes over the support members 4 and 5 in the middle of the guide rail 25, the rollers 23 are weighed by the load cells 40 and 41. Based on the weighing of the left and right sides of the hopper 1, the solenoid pin 30 is removed from the switching rail 26 at the sorting position through which the hopper 1 passes by the output of the solenoid 31 from the controller 51, and the hopper 1 is in a downward movement state. Here, the roller 23 of the hopper 1 is guided to move downward through the switching port 32, and the hopper 1 is moved downward through the connecting link 22 in parallel. With this downward movement, the lock lever 33 is rotated around the lever pin 34 to release the locking of the shutter pin 36, and the shutter 7 is rotated downward to open the discharge port 6 (FIG. 5). The object A is dropped from 6 and received by the shooter 47.
[0026]
In such a weighing and sorting operation, when the object A to be weighed contained in the hopper 1 has a relatively flat shape like a living red sea bream, the abdomen B of the red sea bream A is placed on the lower side. The sheet is supplied in a state in which the back portion C is directed upward with the shutter 7 receiving the sheet. At this time, the left and right side portions D are supported by the front and rear regulating surfaces 12, and become as if swimming, and the red sea bream A can maintain a quiet posture, so that the weighing action is stable and accurate. Is
[0027]
Next, points different from the above example will be described mainly based on FIGS. 8 and 9. The hopper 1 is simply in the form of a weighing device for weighing. The hopper 1 is supported on the upper part of the weighing frame 53. The supporting members 4 and 5 are fitted and supported with square shaft-like supports 2 and 3 to maintain the hopper 1 in a vertical posture so as not to tilt forward and backward. ing. A solenoid 31 that opens and closes the shutter 7 is attached to the outer surface of the hopper 31 and is operated to be closed by energization and opened by a spring 54 by non-energization.
[0028]
A pedestal 55 is supported on the bottom of the weighing frame 53 via a buffer member such as a spring 56, so that the impact can be reduced. A container or a plastic bag 57 can be placed on the receiving table 55 to directly receive and accommodate the red sea bream A dropped from the discharge port 6. Reference numeral 58 denotes a supply guide made of rubber or the like, which is attached to the upper portion of the weighing frame 53 with the discharge port 6 looking upward.
[0029]
When the red sea bream A is supplied to the hopper 1 one by one and weighed, the shutter 7 is opened for a certain time by the solenoid 31 by this weighing, and the red sea bream A is dropped and supplied from the discharge port 6 into the plastic bag 57. Oxygen is injected into the plastic bag 57 so that the red sea bream A can be kept alive and handled or transported.
