Description

【0001】
【発明の属する技術分野】
本発明は野菜、魚等の生鮮食品を収容した食品通箱に所定量の氷を自動投入する装置に関する。
【0002】
【従来の技術】
従来上記食品通箱内への氷の投入は作業員が氷貯槽からスコップを用いて一つ一つ目分量で同通箱内への投入を行う等、人手に依存しているのが実状であり、経済性や生産性の側面からその合理化が課題となっている。
【0003】
又氷貯槽の氷投入口の下に上記食品通箱を置き、氷投入口をその都度開いて定重量の氷を投入することを考えた場合、食品通箱が必要とする氷の量、即ち食品通箱内に収容されている食品の量に応じて必要な量の氷を適切に投入する課題を達成し難い。
【0004】
投入すべき氷の量は食品通箱の容積や収容されている食品の種類と量等によって適切な投入量が定められることが品質管理の上で望ましい。
【0005】
上記氷投入装置によっても、この課題に充分に応えることができず、生産性や労力軽減の面での課題が充分に解決できず、品質管理上安全性を見込んだ過大な量の氷を投入する等の不経済性を伴う。
【0006】
【課題を解決するための手段】
本発明は食品通箱が必要とする氷の量、即ち食品通箱内に収容されている食品の量に応じた適正な量の氷を自動投入することができる食品通箱内への自動氷投入装置を提供する。
【0007】
又食品通箱内に事前に投入されている氷の溶融量に応じた適正な量の追氷が自動的に行える食品通箱内への自動氷投入装置を提供する。
【0008】
本発明は食品を収容した食品通箱をコンベアにより連続的に搬送しつつ、該搬送ライン上において上記各食品通箱内へ氷を自動投入する装置である。
【0009】
この装置は上記コンベアによる搬送ライン上に重量計測ステーションを設け、該重量計測ステーションに各食品通箱の重量を計測する重量計測装置を配する。この重量測定によって各食品通箱に投入すべき氷の量、追氷量を把握する。
【0010】
そして上記重量計測ステーションの搬出側の搬送ライン上に氷投入ステーションを設け、該氷投入ステーションに上記重量計測装置からの重量計測信号により各食品通箱内へ該計測信号に応じた量の氷を投入する氷投入装置を配し、協働して食品通箱内に収容されている食品の量に応じた適正な量の氷を自動投入し、又は食品通箱内に事前に投入されている氷の溶融量に応じた適正な量の氷を自動的に追氷投入する。
【0011】
上記追氷投入を要する食品通箱は、食品を収容し且つ事前に氷が投入されて輸送に供された通箱である。この通箱は上記事前投入氷の溶融水を排出する排水口を有する。
【0012】
上記食品通箱が追氷を要する通箱である場合には、該通箱を上記コンベアによる搬送ラインに流し、この搬送ライン上に氷破砕ステーションを設け、該氷破砕ステーションに上記事前に投入された氷の結氷を破砕する氷破砕装置を配する。
【0013】
そして上記氷破砕ステーションの搬出側の搬送ライン上に重量計測ステーションを設け、該重量計測ステーションに各食品通箱の重量を計測する重量計測装置を配し、更に該重量計測ステーションの搬出側の搬送ライン上に氷投入ステーションを設け、該氷投入ステーションに上記重量計測装置からの重量計測信号により各食品通箱内へ同計測信号に応じた量の氷を追氷投入する。
【0014】
事前に氷が投入されて長時間輸送された食品通箱は輸送中に通箱の開口面に板状に結氷している場合が多く、このままでは追氷が困難であるが上記氷破砕装置はこの結氷板を破砕し、追氷を適正に実行可能とする。
【0015】
事前に氷が投入され輸送に供された食品通箱は輸送中に氷が溶融するが、上記重量計測装置は主としてこの氷の溶融量を計測して必要な追氷量を把握し、氷投入装置による必要な追氷を実行する。
【0016】
上記氷破砕ステーションの搬出側の搬送ライン上には破砕氷払掃ステーションを設け、該破砕氷払掃ステーションに上記氷破砕装置によって破砕されて食品通箱上に散乱する氷を食品通箱搬送下において払掃する破砕氷払掃装置を配し、破砕氷を除去した上で上記重量計測装置にかけ、追氷量の外乱要因を取り除く。
【0017】
上記各食品通箱内への自動氷投入装置においては、上記氷投入ステーションの搬出側の搬送ライン上に氷均しステーションを設け、該氷均しステーションに上記氷が投入された食品通箱に振動を与えて該投入氷を均す氷均し装置を配する。
【0018】
氷投入装置によって投入された氷は食品通箱の開口部において盛り上がっており、又食品間への浸入が不充分である。
【0019】
上記氷均し装置は食品通箱内に投入された氷を収容されている食品の表面を均一に覆うように均すと共に、食品表層部の食品間への氷浸入を助成する。
【0020】
【発明の実施の形態】
以下本発明の実施の形態を図1乃至図13に基づいて説明する。
【0021】
図1Aに示すように、魚、野菜等の食品1は防水処理を施した段ボール箱や発泡スチロール等の合成樹脂製箱等の食品通箱2内に定量小分けして輸送等の流通に供される。
【0022】
前記の通り、これら食品通箱2内に事前に投入された氷3は輸送中に溶融が進むので輸送拠点において追氷が必要となる。その代表例は輸入ブロッコリーである。
【0023】
図1Aに示すように、現在、輸入ブロッコリーの多くは内面に防水処理を施した段ボール箱から成る食品通箱2内に収容され、その表面に小塊の氷3を投入し、船による輸送に供されている。
【0024】
図1Cに示すように、この食品通箱2の底板には輸送中における氷3の溶融水を排出する多数の排水口4が設けられ、輸入先の港において各食品通箱2内への上記追氷が行われている場合が多い。
【0025】
これら追氷は例えば港内の施設で手作業によって行われ、その作業のために多大な時間と労力とコストを要し、流通効率を悪化しているのが実態である。
【0026】
他方事前に氷3が投入されていない食品通箱内2に市場等において氷3を投入する場合、即ち発泡スチロール等の食品通箱2内に定量の魚等を投入し、その表面に最初に氷3を投入する作業も多くは手作業に依存しているのが実態であり、上記と同様の問題を有している。
【0027】
以下図2,図3,図4に基づき上記食品通箱2内に追氷を行う自動氷投入装置の実施形態について説明する。この装置は上記食品通箱2内に新たな氷3を投入する装置を含んでいる。
(1)氷破砕ステーション
【0028】
上記事前に氷3が投入された食品通箱2をコンベア5、例えばベルトコンベアにより搬送ライン上に間隔を置いて連続搬送しつつ、この搬送ライン上に氷破砕ステーションST1を設け、該氷破砕ステーションST1に上記事前に投入された氷3の結氷を破砕する氷破砕装置6を設ける。
【0029】
図1Bに示すように、事前に氷3が投入されて長時間輸送された食品通箱2は輸送中に通箱2の開口面に板状に結氷している場合が多く、このままでは追氷が困難であると共に追氷による冷却効果を損なうが、上記氷破砕装置6はこの結氷板7を破砕し、追氷を適正に実行可能とする。
【0030】
上記氷破砕装置6の具体例として図5に示すように、下面に複数の鋭利な破砕爪8を持った破砕板9をシリンダ10にて上下動し、下動時に上記結氷板7を破砕爪8にて破砕する。
【0031】
上記氷破砕装置6に供する食品通箱2はコンベア5、例えばベルトコンベア上に荷受けしつつ、該ベルトコンベアを停止して上記破砕板9を下降し結氷板7の破砕を行い、破砕後ベルトコンベアを再起動して次の破砕氷払掃ステーションST2に供する。
【0032】
(2)破砕氷払掃ステーション
上記氷破砕ステーションST1の搬出側の搬送ライン上には破砕氷払掃ステーションST2を設け、該破砕氷払掃ステーションST2に上記氷破砕装置6によって破砕されて図1Cに示すように、食品通箱2上に散乱する氷3′を食品通箱2の搬送下において払掃する破砕氷払掃装置11を設け、破砕氷3′を除去した上で、次の重量計測ステーションST3に供し、重量計測に及ぼす外乱要因を取り除き、適正な量の追氷を行うことを保証する。
【0033】
上記破砕氷払掃装置11の具体例として図6に示すように、コンベア5、例えばベルトコンベアで搬送している食品通箱2の上面に接触して回転するブラシロール12を設け、食品通箱2を搬送しつつ同通箱2の上面に散乱している破砕氷3′を上記ブラシロール12にて払い出し、次の重量計測ステーションST3に供する。
【0034】
(3)重量計測ステーション
上記氷破砕ステーションST1の搬出側の搬送ライン上、即ち破砕氷払掃ステーションST2の搬出側の搬送ライン上に重量計測ステーションST3を設け、該重量計測ステーションST3に各食品通箱2の重量を計測する重量計測装置13を配する。
【0035】
前記の通り、事前に氷3が投入されている輸送中の食品通箱2は輸送中に氷3が溶融するが、上記重量計測装置13は主としてこの氷3の溶融量を計測して必要な追氷量を把握し、次に述べる氷投入ステーションST5に設けた氷投入装置14による必要な追氷を実行する。
【0036】
又上記事前に氷3が投入されていない食品通箱2内に新たな氷3を投入する場合、上記重量計測装置13は食品1が投入されている食品通箱2の重量を計測し、該食品通箱2内に投入されている食品1の量に応じた所要の氷投入量を把握し、次に述べる氷投入ステーションST5に設けた氷投入装置14による所要量の氷投入を実行する。
【0037】
容量の異なる食品通箱2、従って収容している食品1の重量が異なる食品通箱2が自動氷投入装置14に供給された場合、上記重量計測装置13はこれら重量の異なる食品通箱2の重量を夫々計測し、これに応じた氷3の投入量を検出把握する。
【0038】
図7は上記重量計測装置13の具体例を示している。この具体例における重量計測装置13はコンベア5a、例えばベルトコンベアを荷受けしつつ、コンベア5a上に荷受けされた食品通箱2の重量を測定する構造を有する。
【0039】
即ち重量計測装置13の上位に固有のコンベア5aを配し、該コンベア5aを支持脚15にて重量計測装置13の荷受け面16にて支承するよう一体構造とする。よって重量計測装置13は食品通箱2とコンベア5aの重量からコンベア5aの重量を差し引き重量計測信号S1として出力し、次に述べる氷投入ステーションST5における氷投入量を制御する。
【0040】
上記コンベア5aの搬入端側にはコンベア5a上に搬入される食品通箱2の終端を検出するセンサー24を設け、食品通箱2の全体がコンベア5a上に搬入されたことを検出し、上記重量計測装置13による重量計測を行う。
【0041】
上記ベルトコンベア5aの搬入端には一段又は二段以上のベルトコンベア5を連続して設け、該コンベア5上に前記氷破砕ステーションST1と破砕氷払掃ステーションST2を形成する。
【0042】
又ベルトコンベア5aの搬出端には別のベルトコンベア5bを連続して配し、該ベルトコンベア5b上に重量計測後の食品通箱2の待機ステーションST4を形成し、図8に示すように、該待機ステーションST4に食品通箱2の前当て22を設け、該前当て22をシリンダ23等にてタイミング的に進退せしめ、前進によって食品通箱2の前面に当接し送りを停止する。
【0043】
即ち次に述べる氷投入ステーションST5における氷投入が完了するまで食品通箱2の送りを停止し、氷投入の完了後、前当て22を後退せしめて送り停止を解除し、氷投入ステーションST5へ向け搬出する。この前当て22は爾後の食品通箱2の氷投入位置を事前に設定する。
【0044】
(4)氷投入ステーション
上記重量計測ステーションST3の搬出側の搬送ライン上、即ち待機ステーションST4の搬出側の搬送ライン上に氷投入ステーションST5を設け、該氷投入ステーションST5に上記重量計測装置13からの重量計測信号S1により各食品通箱2内へ重量計測信号S1に応じた量の氷3を追氷投入する氷投入装置14を配する。
【0045】
図9乃至図12は氷投入装置14の具体例を示している。同図に示すように、投入すべき氷3を貯蔵するホッパー17を備え、該ホッパー17の内底部に投入する氷3を送り出すスクリューコンベア18を横設し、該ホッパー下端の該スクリューコンベア出口端に通箱2内へ氷3を投入する投入口19を設ける。
【0046】
ホッパー17内の氷3はスクリューコンベア18によって側方へ搬出し、上記投入口19を通じて食品通箱2内へ投入する。
【0047】
上記スクリューコンベア18はサーボモーター20にて回転し、該サーボモーター20の回転時間を上記重量計測信号S1にて設定し制御する。再述すると、
【0048】
▲1▼搬送ライン上の重量計測装置13にて食品通箱2の重量を計測し、不足重量データを検出する。
【0049】
▲2▼重量計測装置13は上記不足重量データ信号を重量計測信号S1として制御盤21に送ると共に、氷投入可信号を制御盤21に送る。
【0050】
▲3▼制御盤21は上記重量計測信号S1を時間に置き換える演算を行い、この時間信号を氷投入装置14のサーボモーター20に送る。
【0051】
▲4▼上記信号に基づきサーボモーター20を指定時間駆動し、よってスクリューコンベア18を指定時間回転し、指定量の追氷投入を行う。即ち不足重量データ信号分の氷3を食品通箱2内に投入する。
【0052】
▲5▼氷投入装置14による氷投入が完了すると氷投入完了信号を制御盤21に送り、該制御盤21によりコンベアを駆動し、次の氷均しステーションST6に搬出する。
【0053】
他方食品通箱2によっては氷3の溶融量が許容限度内にあり、この場合には上記重量計測装置13にて通箱2の重量を計測し、氷3の量が適量と判断し、不足重量データ信号を制御盤21に出力せず、よって氷投入装置14による氷投入を行わず、次に述べる氷均しステーションST6に搬出する。
【0054】
又上記ホッパー17内には氷アジテーターを設け、ホッパー17内で結氷した氷3を分散する。この氷アジテーターの具体例として上記スクリューコンベア18と並行して単数又は複数の撹拌シャフト26を設け、該撹拌シャフト26の周面から軸方向に間隔を置いて多数の撹拌ピン27を突設し、撹拌シャフト26をモーター28により回転させることにより、ホッパー17内の貯蔵氷3を撹拌ピン27にて撹拌し分散する。
【0055】
上記撹拌シャフト26は三角形の各頂点に配置した一本の上部撹拌シャフトと二本の下部撹拌シャフトとから成り、該下部撹拌シャフトの下位に既述したスクリューコンベア18を配する。
【0056】
上記氷投入ステーションST5における食品通箱2の荷台は駆動ローラーから成るローラコンベア5cにて形成する。該駆動ローラーコンベア5cは氷投入中は停止し、氷投入後に駆動して食品通箱2を氷投入ステーションST5から該駆動ローラーコンベア5cの搬出端に連続して設けたコンベア5d上に搬出し、該コンベア5dを介してその搬出端に設けた氷均しステーションST6へ搬出する。
(5)氷均しステーション
【0057】
この氷均しステーションST6には上記氷3が投入された食品通箱2に振動を与えて該投入氷を均す氷均し装置25を配する。
【0058】
氷投入装置14によって投入された氷3は食品通箱2の開口部において盛り上がっており、又食品1間への浸入が不充分である。
【0059】
上記氷均し装置25は氷3が食品通箱2内に収容されている食品1の表面を均一に覆い、表層部の食品1間への氷浸入を助成する。
【0060】
図13A、Bは上記氷均し装置25の具体例を示している。図示のようにこの氷均し装置25は基本的にはローラーコンベア5eにより構成され、複数本のローラー29を並設し、該各ローラー29の周面に周方向と軸方向に間隔を置いて多数本の送りピン30を突設し、例えば周方向に一定間隔に四本乃至六本等の送りピン30を突設し、該送りピン30を軸方向に間隔を置いて多数突設する。
【0061】
食品通箱2は図13Aに示すように、ローラー29の回転に伴い送りピン30のうちの周方向の各一本が垂直に起立した時に食品通箱2を上死点まで突き上げ、図13Bに示すように、周方向の各二本が垂直線の左側と右側に対称に持ち来された時に下死点まで下降し、両動作の繰り返しにより食品通箱2を上下に振動する。この結果食品通箱2内に投入された氷3を均し処理する。
【0062】
又上記ローラーコンベア5eは食品通箱2を上記均し動作を惹起しつつ搬入端から搬出端へ搬送する。即ちローラーコンベア5eはアジテーター手段と、搬送手段とを兼務する。
【0063】
上記説明は追氷投入装置について述べたが、食品通箱2内に事前に投入した氷3が存在せず、新たな氷3を投入する場合には、氷破砕ステーションST1と破砕氷払掃ステーションST2を設けずに、魚等や野菜等の食品1が投入された食品通箱2を直接重量計測ステーションST3に供し、氷投入ステーションST5と氷均しステーションST6に供する。
【0064】
事前に氷3が投入されていない食品通箱2に投入すべき新たな氷3の量は、食品通箱2の容積や収容されている食品1の種類と量等によって適切な投入量が定められることが品質管理の上で望ましい。重量計測ステーションST3においては、重量計測装置13上に搬入された通箱2の容量、即ち食品重量に応じ、これを測定して氷投入装置14による氷投入量を指令する。
【0065】
【発明の効果】
以上によって食品通箱内への新たな氷の投入並びに追氷投入の自動化と、合理化が適切に達成でき、省力化、食品通箱の流通効率の向上、コスト削減等を達成できる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to an apparatus for automatically pouring a predetermined amount of ice into a food box containing fresh food such as vegetables and fish.
[0002]
[Prior art]
Conventionally, the input of ice into the above-mentioned food box is dependent on humans, such as the worker using the scoop to put the ice into the same box one by one from the ice storage tank. Therefore, rationalization is an issue from the aspects of economy and productivity.
[0003]
In addition, when the food bin is placed under the ice inlet of the ice storage tank and the ice inlet is opened each time and a constant weight of ice is thrown in, the amount of ice required by the food bin, that is, It is difficult to achieve the task of properly putting the required amount of ice in accordance with the amount of food contained in the food container.
[0004]
It is desirable from the viewpoint of quality control that an appropriate amount of ice to be charged is determined according to the volume of the food box, the type and amount of food contained, and the like.
[0005]
Even with the above-mentioned ice dispenser, this problem could not be fully met, and the problems in terms of productivity and labor reduction could not be sufficiently solved. Uneconomical cost.
[0006]
[Means for Solving the Problems]
The present invention relates to an automatic ice box in a food bin that can automatically feed an appropriate amount of ice according to the amount of ice required by the food bin, that is, the amount of food contained in the food bin. An input device is provided.
[0007]
In addition, there is provided an automatic ice feeding device into a food container, which can automatically add an appropriate amount of ice according to the amount of ice previously charged into the food container.
[0008]
The present invention is an apparatus for automatically feeding ice into each of the food containers on the transport line while continuously transporting the food containers containing the foods by a conveyor.
[0009]
In this apparatus, a weight measuring station is provided on a transport line by the above-mentioned conveyor, and a weight measuring device for measuring the weight of each food box is arranged in the weight measuring station. By this weight measurement, the amount of ice to be put into each food box and the amount of additional ice are grasped.
[0010]
An ice loading station is provided on the transfer line on the unloading side of the weight measuring station, and the ice loading station supplies an amount of ice according to the measurement signal into each food container by a weight measurement signal from the weight measuring device. An ice input device to be put in is arranged, and the proper amount of ice corresponding to the amount of food contained in the food box is automatically put in cooperation with the food box, or it is put in advance in the food box. An appropriate amount of ice is automatically added according to the melting amount of ice.
[0011]
The food container that requires additional ice is a container that accommodates food and is supplied with ice and transported in advance. This pass box has a drain port for discharging the molten water of the pre-charged ice.
[0012]
When the food container is a container requiring additional ice, the container is passed through a conveyor line provided with the conveyor, and an ice crushing station is provided on the conveyor line. An ice crusher for crushing frozen ice is provided.
[0013]
A weight measuring station is provided on a transport line on the unloading side of the ice crushing station, and a weight measuring device for measuring the weight of each food container is arranged at the weight measuring station. An ice charging station is provided on the line, and ice is added to the ice charging station in accordance with the weight measurement signal from the weight measuring device into each food storage box in accordance with the measurement signal.
[0014]
In many cases, food cartons that have been transported for a long time after ice has been put in them are often frozen in a plate shape on the opening surface of the cart during transport, and it is difficult to pursue ice as it is. This icing plate is crushed so that additional ice can be properly executed.
[0015]
Ice is melted during transportation in the food boxes that have been loaded with ice and transported in advance, but the weight measurement device mainly measures the melting amount of this ice to determine the required amount of additional ice, and then loads the ice.
