【０００１】
【産業上の利用分野】
この発明は、食肉スライサーが切り落とすスライス片をベルトコンベア上に受け取って、その搬出過程において自動的に前後に二つ折りに折り畳むようにした食肉スライス片の折畳処理方法とその装置に関し、コンベアの搬送面にバーを供給してその上にスライス片を落下させ、次いでこのバーを持ち上げて二つ折りにし、再びコンベア上にバーとともに二つ折りしたスライス片を戻した後にバーを抜き取ることにより、特に生肉のように軟らかい食肉スライス片の切断時の形状を維持しつつ前後に二つ折りするようにしたことを特長とする。
【０００２】
【従来の技術】
櫛状に並べた複数本のバーにそれぞれスライス片の真中を掛けて二つ折りにした後、バーの向きを変え、載置面上に降ろしてバーを抜き取って、二つ折りしたスライス片を複数枚毎に鱗列状に並べるようにした装置には、例えば特開平６ー３１５３４０号公報がある。
また、食肉スライサーが切り落とすスライス片の落下位置に、多条形の搬送面を備えたコンベアを設置してスライス片を受け取るとともに、上記搬送面の間から櫛歯形の折畳み部材を反転させて、スライス片を二つ折りするようにしたものには特公平３ー６６２１３号公報がある。
【０００３】
【発明が解決しようとする課題】
前者は、バーを所定間隔で櫛歯状に並べた受取り部材を用いるので、食肉スライサーに直結して切り落とされるスライス片が自動的にバーに掛けられるようにするには、技術的にまたスペース的に困難があり、手掛け作業に頼るほかなく、二つ折りの完全な自動化は見込めない。
【０００４】
後者は、スライス片の落下位置で櫛歯形の折畳み部材を後側または前側から約１８０°往復反転させてスライス片を二つ折りするので、スライス片の切断時の形状を損ね易い多条形の搬送面を備えたコンベアを使用する必要があることの他、切り落とされて平に受け取られたスライス片の後半または前半を反転させて折り返すことと、受け取ったその場で次の切断周期に間に合わせるために急速に折り畳む必要があることなどから、生肉のように軟らかい食肉スライス片の場合には、接触面に張り付いたり、スライス片が腰折れするなどして切断面の形状維持が難しいという欠点があった。
【０００５】
以上のことから、軟らかく薄い食肉スライス片の切断時の形状をできるだけ損なわないように維持しつつ、扁平状態のスライス片を無理なく二つ折りできるようにした食肉スライス片の折畳処理方法とそれに使用する装置を開発することが解決すべき課題となっていた。
【０００６】
【課題を解決するための手段】
そこで本発明は、スライサーが所定の周期で切り落とす各スライス片を、それぞれ搬送面上に横断して置かれたバーに上からかぶせつつ、かつ、互いに前後に間隔を開けて、第１のベルトコンベア上に扁平状態のまま受け取らせる第一工程、上記第１のベルトコンベアの搬送面上からバーの両端を上昇させて、該バー上でスライス片を前後に二つ折りする第二工程、第二工程で上昇させたバーを下降させつつ、二つ折りしたスライス片をバーととも比較的に低速走行する第２のベルトコンベアの始端部に接地させて、該コンベア上に順次移乗させることにより、二つ折りしたスライス片を搬送方向に沿って鱗列状に並べる第三工程、第三工程で鱗列状に並べられて第２のベルトコンベア上をそれぞれ搬送されつつある複数毎のスライス片からコンベアの側方に向けて、バーを横に抜き出す第四工程、以上の工程を有する食肉スライス片の折畳処理方法を提供するものである。
【０００７】
また本発明は、本発明折畳処理方法を実施する装置として、
所定の周期で食肉塊をスライスするスライサー、
搬送面をスライス片の切り落とし位置に置き、搬送面の始端側に、スライサーの切断周期に同調してバーを搬送面の横断方向に供給するバーホッパーを備え、このバーホッパーから供給されるバーを両側縁に設けた掛止部に掛止してスライス片の切り落とし位置に搬送し、各バーの上にかぶさるスライス片をそれぞれ扁平状態に、かつ、前後に間隔を開けて受け取る第１のベルトコンベア、
第１のベルトコンベアの終端部の両側にそって設けられ、コンベアベルトの両側に突出するバーの両端を下から支承して該バー上のスライス片を前後に二つ折りするように持ち上げる前後二組の支持杆と、この支持杆を取り付けて、かつ、該コンベアと同方向に等速に走行しつつバーの載置間隔に対応して二組の支持杆を交互に昇降させるように無端の長円形軌道をえがく軌道体とからなるバーの昇降装置、
第１のベルトコンベアと略同幅で延長方向に伸びる搬送面を有し、かつ、同コンベアよりも適宜に低速の周速度で循環し、始端部を第１のベルトコンベアの終端部に接近させ、かつ、該始端部の両側に、バーの昇降装置の支持杆の下降位置を位置させて、該位置で下降する支持杆からバーとともに二つ折りされたスライス片を第１のベルトコンベアの終端部から順次移乗させることにより、搬送方向に沿って二つ折りしたスライス片を鱗列状に並べる第２のベルトコンベア、
第２のベルトコンベアの中間の一側方に設けられ、先端を該コンベアの側縁に接近させて互いに上下に揺動自在に備えられ、開閉機構に連なって適時に開閉する上下２組のアームと、各組のアームの先端にそれぞれ回転自在に備えられて、この上下２組のアームの揺動により、第２のベルトコンベアに搬送されつつある複数本のバーの一端を搬送方向にそって挟持する上下一対のローラーと、上下一対のローラーをバーの抜取方向に回転駆動する抜取駆動機構と、バーを挟持して抜取方向に回転駆動される上下一対のローラーととともに、上下２組のアームを、第２のベルトコンベアの搬送面と同方向に等速に移動させた後、急速に抜取位置に復帰するローラー往復機構とからなるバーの抜取装置、
以上の各構成を一連に具備してなる食肉スライス片の折畳処理装置を提供するものである。
【０００７】
本発明において、前記第１のベルトコンベアを、前記スライサーの切断周期に同調して駆動するとともに、スライサーの切断周期に対して差動させることにより、スライス片の折り畳み位置を前後に調整可能にして、例えば二つ折りするスライス片の前後の割合を真半分に限らず、例えば２対８とか３対７とか４対６とかのように折り畳みの割合を希望する割合に変更し、スライス片の望ましい表面を表にして並べられるようにすることができる。
【０００８】
また本発明において、前記第１のベルトコンベアの終端部の搬送面の高さを、前記第２のベルトコンベアの始端部の搬送面の高さよりも低くすることにより、二つ折りされたスライス片の後部長さの長い場合に、第２のベルトコンベアへの移乗を円滑に行わせるようにすることができる。
【０００９】
また本発明において、前記第２のベルトコンベアの始端部の下方と、前記第１のベルトコンベアの終端部の搬送曲面との間に、スクレーパーを掛け渡すことにより、粘着性のあるスライス片の後部が第１のベルトコンベアの終端部の搬送曲面に付着して巻き込まれることを防止することができる。
【００１０】
【作用】
本発明は、
ａ．搬送面の扁平な第１のベルトコンベア上にスライサーの切断周期に応じた所定間隔を保持させつつバーを供給して、その上からスライス片を切り落とさせて扁平状態に受け取らせるようにしたので、スライス片の切断時の形状の維持が容易である。
ｂ．バー上でスライス片を二つ折りするときは、バーを第１のベルトコンベアと等速に走行させつつ上昇させるので、搬送面からのスライス片の分離が無理なくスムーズに行われ、伸び縮みする割合が低いので、スライス片の切断時の形状の維持が容易である。
ｃ．バーの上昇により二つ折りされたスライス片が下降するときは、第１のベルトコンベアよりも低速に走行する第２のベルトコンベア上に受け取られるので、少しずつずれて前後のスライス片が重なり合い、自動的に鱗列状態を順次形成する。
また第２のベルトコンベアは、その始端部を第１のベルトコンベアの終端部の延長方向に接近させているので、スライス片の特に後部の乗り移りがスムーズに行われ、移乗の際のスライス片の形状の維持も容易である。
ｄ．スライス片を二つ折りした後のバーは、低速に走行する第２のベルトコンベア上に鱗列状態に重ね合わされたスライス片にそって横に等速に移動しながら複数本毎に側方へ抜き出すので、二つ折りしたスライス片の形状維持を含めて鱗列状態の維持が良くできる。
【００１１】
【実施例】
以下に本発明の実施例を図面について説明する。
図１の(a),(b),(c) 図に示すように、本発明折畳処理方法は、四つの工程よりなる。
第１工程は、図１の(a) に示すように、搬送面をスライサーの切断位置の真下に接近させて図示左行する第１のベルトコンベア１上に、スライサーＳの切断周期に同調させてバー２を搬送面の横断方向に供給し、その上からスライサーＳにスライス片３を切り落とさせることにより、それぞれ裏面にバー２を挿通させた状態で各スライス片３を扁平状態のまま、前後に少しの間隔を開けて順次第１のベルトコンベア１上に受け取らせる。
【００１１】
第２工程は、図１(b) の右手に示すように、第１のベルトコンベア１の終端部１’の両側において、コンベアベルトの両側に突出するバー２の両端に、下から上昇させてきたバー支持杆４の上端を係合させて、バー２とともにスライス片３を搬送面上から持ち上げる。この時、スライス片３の前部は、第１のベルトコンベア１が終端部１’の曲面に差し掛かる位置に当たるので、コンベア１からの剥離がスムーズにできる。一方、当該スライス片３の後端の分離も、第１のベルトコンベア１の走行に伴って終端部の曲面に差し掛かることと、該コンベア１と平行して等速にバー支持杆４の横走行が行われることとにより、搬送面からの剥離に際する伸び縮みはきわめて少ない。
【００１２】
第３工程は、図１(b) の左手に示すように、第２のベルトコンベア５の始端部５’の両側において、バー支持杆４が下降し、前工程で二つ折りしたスライス片３をバー２とともに第２のベルトコンベア５に移乗させる工程である。
第２のベルトコンベア５の始端部５’の両側でバー支持杆４が下降すると、バー２がスライス片３とともに、第２のベルトコンベア５の始端部上に受け渡される。この時二つ折りのスライス片３の後端部は、第１のベルトコンベア１の終端部１’の曲面から離れて、第２のベルトコンベア５の始端部５’の曲面に乗り移る。
第２のベルトコンベア５の走行速度は、第１のベルトコンベア１の速さに較べて例えば１／１０程度の低速に設定することにより、後続のスライス片３が先のスライス片３の後に順順に重なり、図示のように鱗列状態を形成する。
【００１３】
第４工程は、図１(c) に示すように、第２のベルトコンベア５の搬送面上に鱗列した各スライス片３のバー２を抜取装置６が複数本ずつ毎に横へ抜き取る工程である。
バーの抜取装置６は、第２のベルトコンベア５の一側方に設けらて、コンベア５の側縁に沿って平行し、互いにバーを抜き取る方向に自転しつつ、接離し合うように設けた上下一対のローラー７、８と、先端に上下のローラーの両端をそれぞれ回転自在に軸支し、かつ、互いに上下に揺動する上下２組のアーム９、１０とを有する。
【００１４】
この抜取装置６は、後述のように適時に上下２組のアーム９、１０を揺動させて、ローラー７、８の間に第２のベルトコンベア５上に並ぶ複数本のバー２の一端を挟持し、ローラー７、８の回転により鱗列しているスライス片３からバー２を横に抜き出しつつ、第２のベルトコンベア５の走行方向に添って等速に移動し、バー２を抜き終えた後にアーム９、１０を開くとともに急速に抜取位置に復帰して、その間に搬送されてきている次位の複数本のバー２を挟持して抜き出すという動作を反復する。
【００１５】
次に、本発明装置の実施例を図２、３について説明する。
図２に示す部分は、主として前記第１工程、第２工程を行う部分である。
図２において、第１のベルトコンベア１は、右から左に搬送面を走行させ、始端部上方にバーホッパー１１を設け、スライサーＳの切断周期に同調して作動するフィーダー１２から１本ずつ搬送面の横断方向に供給されるバー２をコンベアベルトの両側縁に前後に所定間隔で突起状に設けた掛止部１３（図１参照）に掛止して、所定の周期で図示左右に往復するスライサーＳの丸刃Ａの裏面に接近した位置へ搬送する。
【００１６】
スライサーＳは従来公知のもので、上部に設置した固定保持部１４と可動保持部１５とで構成した肉箱Ｂから送り出す食肉塊Ｍを、往復する丸刃Ａで下端から順次スライス片３にして切り落とす。
切り離される各スライス片３は上からバー２にかぶさり、それぞれ裏面にバー２を挿通した状態で第１のベルトコンベア１上に扁平状態に受け取られる。
【００１７】
第１のベルトコンベア１の終端部１’の両側には、スライス片３の裏面に挿通したバー２の両端を下から支承して第１のベルトコンベア１上から持ち上げ、バー２上でスライス片３を前後に二つ折りする前後二組の支持杆４と、この支持杆４を取り付け、かつ、第１のベルトコンベア１と同方向に等速に走行しつつバー２の載置間隔に対応して二組の支持杆４を交互に昇降させるように長円形軌道をえがく軌道体１６とからなるバーの昇降装置１７が付設されている。
【００１８】
第１のベルトコンベア１は、スライサーＳの丸刃Ａを往復駆動するクランク軸１８を原動軸とする駆動経路１９に駆動されて、丸刃Ａを１往復させるクランク軸１８の１回転間に、肉箱Ｂの固定保持部１４と可動保持部１５との間に挟持される材料の最大積載許容幅を若干上回る長さを走行するようにその速度を設定されていて、スライサーＳの切断周期に同調して駆動されるとともに、切り落とされる各スライス片３の間に少しの間隔を形成させる。
【００１９】
また、第１のベルトコンベア１の駆動経路１９中には、差動歯車式位相調整装置２０が介設されている。この差動歯車式位相調整装置２０を操作すると、スライサーＳの切断周期の中で第１のベルトコンベア１に差動を生じさせることがでる。
第１のベルトコンベア１が差動すると、バー２上に切り落とされるスライス片３の受取位置は前後に調整される。例えばバー２の挿通位置をスライス片３の真半分に限らず、前後に２対８とか３対７とか４対６というように動かすと、１枚のスライス片３の中の折り曲げ位置を移動し、それによって、鱗列状にした後のスライス片３の外観上の見栄えを良くすることができる。
【００２０】
前記バーの昇降装置１７は、第１のベルトコンベア１の原動ローラー２１と調帯２２を介して前記軌道体１６を駆動することにより、第１のベルトコンベア１の走行に、バーの支持杆４の昇降と横走行を同調させる。
なお図中、２３は第１のベルトコンベア１のみを走行させる場合に使用するモーターで、伝動帯２３’を介して第１のベルトコンベア１の前記原動ローラー２１を駆動するように備えられている。
【００２１】
次に本発明の第３、第４工程を行う後半部分の装置を図３、４、５について説明する。
図３に示すように、第２のベルトコンベア５は、始端部５’（図示右手）を第１のベルトコンベア１の終端部１’に接近させて、延長方向に略同等の幅で接続する搬送面を具え、図示左端のモーター２４に駆動されて同方向に約１／１０の速度で循環する。
【００２２】
第２のベルトコンベア５の始端部５’は、その両側に前記バーの昇降装置１７の後半を位置させ、軌道体１６によって搬送されて下降しつつある支持杆４からバー２とともに二つ折りされたスライス片３を受け取る。なおこの時、次位の支持杆４は次のバー２と係合する位置に達するように取り付けられている。
上記のようにこの第２のベルトコンベア５は、低速走行する搬送面に二つ折りされたスライス片３を第１のベルトコンベア１の終端部１’から順次移乗させることにより、先のスライス片３の後部に後続のスライス片３の前部が重なり、図１の(b)(c)に示すような鱗列状態を形成させつつスライス片３を搬出する。
【００２３】
鱗列状態のスライス片３からバー２を横に抜き取る抜取装置６は、第２のベルトコンベア５の中間の一側方（搬送方向右手）に備えられている。
図４に示すように、バーの抜取装置６は、まず第２のベルトコンベア２３の側縁に平行に沿って互いに接離するように備えられ、該コンベア上に並ぶ複数本のバー２の端部を一度に挟持する長さを具えた上下一対のローラー７、８と、ローラー７、８の両端をそれぞれ回転自在に先端に軸支して揺動自在に備えられ、適時に開閉する上下２組のアーム９、１０を具備する。
【００２４】
上下一対のローラー７、８をバーの抜取方向に回転駆動する抜取駆動機構２５は、図４、５に示すように、上下一対のローラー７、８の外端にそれぞれ固定したピニオン２６、２７と、アーム９、１０の一側に沿ってピニオン２６、２７にそれぞれ掛け渡した上下のタイミングベルト式の回転伝動帯２８、２９と、アーム９、１０の揺動支点軸３０、３１とそれぞれ同軸上に備えられ、互いに噛み合って、一側に一体に設けた大プーリー２８’、２９’を介し、上記回転伝動帯２８、２９を互いに等速に循環駆動する上下一対の歯車３２、３３と、一方の歯車３２に出力軸を直結した抜取用モーター３４を備えている。
【００２５】
上下２組のアーム９、１０を適時に開閉して、ローラー７、８を接離させる開閉機構３５は、図５に示すように、上側のアーム９の基部に固定されて垂下し、該アーム９の揺動支点軸３０を支点とするカムレバー３６と、カムレバー３６の下端に備えた転子３７と当接してその高所ａと低所ｂで該カムレバー３６に振幅をあたえる円板カム３８と、第２のベルトコンベア５上に所定数のバー２が載る時間間隔内に円板カム３８を１回転させるモーター３９と、両アーム９、１０の基部で互いに係合するように設けられて、カムレバー３６の揺動を下側のアーム１０の揺動に伝達する上下一対の突起４０、４１ならびに両突起４０、４１間にねじこまれてローラー７、８の圧接程度を調整する調節ねじ４２とからなる。
【００２５】
またバーの抜取装置６は、同じく図４、５に示すように、上記上下一対のローラー７、８と上下２組のアーム９、１０と抜取駆動機構２５および開閉機構３５を、第２のベルトコンベア２１の搬送面と同方向に等速に一体に移動した後、急速に抜取位置に復帰するローラー往復機構４３を備えている。
【００２６】
常時搬出方向に走行している第２のベルトコンベア５から複数本ずつ毎にバー２を横に抜き出すために、ローラー往復機構４３は、第２のベルトコンベア５を支持する架台４４に設けたガイド軸４５に、筒形のスライダー４６を遊嵌させて、該コンベア２１の走行方向に沿って往復する走行台４７を有する。
【００２７】
走行台４７上には、前記ローラー７、８とアーム９、１０と抜取駆動機構２５および開閉機構３５を搭載する一方、第２のベルトコンベア５の駆動モーター２４に、電磁クラッチ４８を介して間欠駆動される伝動帯４９を設け、この伝動帯４９との間に設けた連結杆５０の牽引により、第２のベルトコンベア５の搬送面と同方向に等速に抜取装置６全体が移動する。
【００２８】
ローラー往復機構４３は、１回に抜き取られるバー２の抜取幅に相当して往復する走行台４７の往行程距離５１を、上記電磁クラッチ４８が接離する作動間隔の中に設定し、架台４４と走行台４７との間に設けた復元ばね５２の付勢により、電磁クラッチ４８の結合から開放された走行台４７を急速に抜取位置へ後退させ、止めねじ５３によりガイド軸４５上に調整可能に設定した復帰位置までスライダー４６を復位させるようにしている。
【００２９】
以上のようにして、バーの抜取装置６によりバー２を複数本ずつ毎に横に抜き出させることにより、二つ折りに折り畳まれて鱗列状に搬出される各スライス片３は鱗列状態を殆ど乱すことなく、また切断形状も満足すべき状態を維持することができた。
【００３０】
更に本発明は、図３に示すように、第１のベルトコンベア１の終端部１’の搬送面の高さを、第２のベルトコンベア５の始端部５’の搬送面の高さよりも低く段差を設けることにより、第１のベルトコンベア１の終端部１’において曲面に沿って下側に回り込もうとするスライス片３の後部の剥離速さと、高い位置で低速回転する第２のベルトコンベア５の始端部５’の搬送面の送り速さとが釣り合って、二つ折りされたスライス片３に伸び縮みの少ない移乗を行わせる。
【００３１】
また本発明は、図６に示すように、第２のベルトコンベア５の始端部５’の下方と、第１のベルトコンベア１の終端部１’が形成する搬送曲面との間に、スクレーパー５４を掛け渡すと、その強制的な剥離作用によって、スライス片３の後部が同曲面に付着したまま逆方向に巻き込まれるようなことが防止されるとともに、第２のベルトコンベア５の速さに応じたスムーズなスライス片３の移乗を生ずる。また、スクレーパー５４は、下縁５４’を開放することにより、バー２から落ちる肉片をコンベア外へ排出させることができる。
【００３２】
なお、上記第１のベルトコンベア１と第２のベルトコンベア５の間の段差と、スクレーパー５４の付設は、それぞれ材料の大きさ、肉質の差異によって必要のない場合もあり、任意の構成である。
【００３３】
【発明の効果】
以上の説明から明らかなように、本発明は、搬送面の扁平な第１のベルトコンベア上にバーを供給して、その上からスライス片を切り落として扁平な状態で受け取らせ、このスライス片を二つ折りするときは、バーを第１のベルトコンベアと等速に走行させつつ上昇させるので、搬送面からのスライス片の分離が無理なくスムーズに行われ、二つ折りする際の伸び縮みする割合が低いので切断形状の維持が容易にできる。
【００３４】
本発明はさらに、バーの上昇により二つ折りしたスライス片が下降するときに、第１のベルトコンベアよりも低速で同方向に走行する第２のベルトコンベアの始端部に受け取らせるので、スライス片が自然と鱗列状態に重ね合わされる。また第２のベルトコンベアは、その始端部を第１のベルトコンベアの終端部の延長方向に、かつ、ほぼ同幅で接近させているので、特にスライス片の後部の乗り移りがスムーズにでき、移乗の際の切断形状の維持も良くできる。
【００３５】
鱗列状態に重ね合わされたスライス片の中からバーを抜き出すときは．低速に走行する第２のベルトコンベア上で複数本毎に、かつ、抜き取るバーの移動と等速にコンベアに沿って抜取装置を移動させながら側方に抜き取るので、スライス片の形状維持とともに鱗列状態が良く維持できる。
【００３６】
以上のようにしてスライス片を二つ折りするようにした本発明は、スライサーに直結した折畳処理を完全に自動化できるので、特に人手を要さず、量販店等における生の食肉のスライス片処理に好適し、かつ、衛生的な処理ができる。

[Industrial application fields]
The present invention relates to a method and apparatus for folding a meat slice piece, which is received on a belt conveyor and sliced by a meat slicer, and is automatically folded in the front and back in the carrying-out process. Feeding the bar on the surface and dropping the slices on it, then lifting the bar and folding it in half, returning the sliced piece together with the bar back onto the conveyor and then pulling out the bar, in particular the raw meat As described above, the soft meat slice piece is folded in the front and back while maintaining the shape at the time of cutting.
[0002]
[Prior art]
Hang the slice piece in the middle of each of the multiple bars arranged in a comb shape and fold it in half, then change the direction of the bar, lower it on the mounting surface, pull out the bar, and fold the sliced piece For example, Japanese Patent Application Laid-Open No. 6-315340 discloses an apparatus arranged in a scale pattern every time.
In addition, a sliced slice is cut by the meat slicer by installing a conveyor having a multi-shaped conveying surface to receive the sliced piece, and the comb-shaped folding member is inverted from between the conveying surfaces to slice the sliced piece. Japanese Examined Patent Publication No. 3-66213 is one in which a piece is folded in half.
[0003]
[Problems to be solved by the invention]
The former uses a receiving member in which bars are arranged in a comb-like shape at a predetermined interval. Therefore, in order to automatically slice slice pieces that are cut directly by being connected to a meat slicer, technically and spatially. However, there is no choice but to rely on the handling work, and it is not possible to fully automate the bi-fold.
[0004]
In the latter, the comb-shaped folding member is reciprocally reversed by 180 ° from the rear side or the front side at the fall position of the slice piece, and the slice piece is folded in half, so that the shape at the time of cutting the slice piece is easily damaged. In addition to the need to use a conveyor with a surface, the second half or the first half of sliced pieces that have been cut and received flatly are turned over and turned back in time to meet the next cutting cycle on the spot In the case of meat slices that are soft like raw meat, it is difficult to maintain the shape of the cut surface because it sticks to the contact surface or the slice breaks back. It was.
[0005]
Based on the above, a method for folding meat slice pieces that can be folded into two without difficulty while maintaining the shape of the slices of soft and thin meat slices as much as possible, and its use It has been a problem to be solved to develop a device to perform.
[0006]
[Means for Solving the Problems]
In view of this, the present invention provides a first belt conveyor in which each slice piece that the slicer cuts off at a predetermined period is covered with a bar placed across the conveying surface from above and spaced apart from each other. The first step for receiving the flat state on the top, the second step for raising both ends of the bar from the conveying surface of the first belt conveyor, and folding the slice piece back and forth on the bar. While lowering the bar raised in step, the sliced piece folded in half is brought into contact with the start end of the second belt conveyor that travels at a relatively low speed together with the bar, and is sequentially transferred onto the conveyor. The third step of arranging the sliced pieces in a scale along the transport direction, from the plurality of slice pieces being arranged in a scale in the third step and being respectively transported on the second belt conveyor Towards the side of the conveyer, the fourth step of withdrawing the bar laterally is to provide a folding method of processing meat slices with the above steps.
[0007]
Moreover, this invention is as an apparatus which implements this folding method,
A slicer for slicing meat chunks in a predetermined cycle,
The transport surface is placed at the cut-off position of the slice piece, and a bar hopper that feeds the bar in the transverse direction of the transport surface in synchronization with the cutting cycle of the slicer is provided on the start end side of the transport surface.

[Action]
The present invention
a. Since the bar is supplied on the first belt conveyor having a flat conveying surface while maintaining a predetermined interval according to the cutting cycle of the slicer, the slice piece is cut off from above and received in a flat state. It is easy to maintain the shape when the slice piece is cut.
b. When folding the slice piece in half on the bar, the bar is raised while running at the same speed as the first belt conveyor, so the slice piece is smoothly separated from the transport surface without difficulty and the rate of expansion and contraction. Therefore, it is easy to maintain the shape when the slice piece is cut.
c. When the slice piece folded in half by the rising of the bar is lowered, it is received on the second belt conveyor running at a lower speed than the first belt conveyor, so that the slice pieces before and after are overlapped little by little. The scale state is formed sequentially.
In addition, since the second belt conveyor has its start end approaching the extending direction of the end of the first belt conveyor, the transfer of the slice piece in particular at the rear is performed smoothly, and the slice piece at the time of transfer is transferred. The shape can be easily maintained.
d. The bars after the slice pieces are folded in half are pulled out side by side while moving at a constant speed along the slice pieces superimposed on the second belt conveyor running at low speed. Therefore, the scale state can be well maintained including the shape maintenance of the slice piece folded in half.

【Example】
Embodiments of the present invention will be described below with reference to the drawings.
As shown in FIGS. 1A, 1B, and 1C, the folding method of the present invention includes four steps.
In the first step, as shown in FIG. 1A, the conveying surface is brought close to the cutting position of the slicer and is synchronized with the cutting cycle of the slicer S on the first belt conveyor 1 that goes to the left in the figure. The bar 2 is fed in the transverse direction of the conveying surface, and the slice piece 3 is cut off from the top by the slicer S, so that each slice piece 3 remains in a flat state with the bar 2 inserted through the back surface. Are sequentially received on the first belt conveyor 1 with a small interval.
[0011]
In the second step, as shown in the right hand of FIG. 1 (b), the both ends of the end portion 1 ′ of the first belt conveyor 1 are raised from below to both ends of the bar 2 protruding on both sides of the conveyor belt. The upper end of the bar support bar 4 is engaged, and the slice piece 3 is lifted from the conveying surface together with the bar 2. At this time, since the front part of the slice piece 3 hits the position where the first belt conveyor 1 reaches the curved surface of the terminal part 1 ′, the peeling from the conveyor 1 can be performed smoothly. On the other hand, the separation of the rear end of the slice piece 3 also reaches the curved surface of the terminal end as the first belt conveyor 1 travels, and the side of the bar support bar 4 parallel to the conveyor 1 at a constant speed. By running, there is very little expansion and contraction when peeling from the conveying surface.
[0012]
In the third step, as shown in the left hand of FIG. 1 (b), on both sides of the starting end portion 5 'of the second belt conveyor 5, the bar support rods 4 are lowered, and the slice piece 3 folded in the previous step is folded. This is a step of transferring to the second belt conveyor 5 together with the bar 2.
When the bar support rods 4 are lowered on both sides of the start end portion 5 ′ of the second belt conveyor 5, the bar 2 is transferred onto the start end portion of the second belt conveyor 5 together with the slice piece 3. At this time, the rear end portion of the half-folded slice piece 3 moves away from the curved surface of the terminal end portion 1 ′ of the first belt conveyor 1 and changes to the curved surface of the start end portion 5 ′ of the second belt conveyor 5.
The traveling speed of the second belt conveyor 5 is set to a low speed of, for example, about 1/10 compared to the speed of the first belt conveyor 1 so that the succeeding slice piece 3 follows the preceding slice piece 3 in order. It overlaps in order and forms a scale state as shown in the figure.
[0013]
As shown in FIG. 1 (c), the fourth step is a step in which the sampling device 6 pulls out the bars 2 of the slice pieces 3 arranged on the transport surface of the second belt conveyor 5 side by side by a plurality of units. It is.

[0014]
As will be described later, the sampling device 6 swings two sets of upper and lower arms 9 and 10 at appropriate times so that one end of the plurality of bars 2 arranged on the second belt conveyor 5 is placed between the rollers 7 and 8. The bar 2 is horizontally pulled out from the sliced pieces 3 that are nipped and rotated by the rotation of the rollers 7 and 8, moved at a constant speed along the traveling direction of the second belt conveyor 5, and the bar 2 is completely pulled out. After that, the operation of opening the arms 9 and 10 and quickly returning to the extraction position and holding and extracting the next plurality of bars 2 being conveyed therebetween is repeated.
