Description

【０００１】
【発明の属する技術分野】
本発明は、食品成形装置、より詳しくは、パン生地、饅頭生地等の外皮材によって、餡、調理した肉・野菜等の内材を確実に包み込み成形することができる食品成形装置に関するものである。
【０００２】
【従来の技術】
こうした外皮材によって内材を包み込む食品成形に関する技術としては、従来より内材を棒状にしてその外側に外皮材を筒状にしたものを連続して形成し、シャッタ機構の開閉動作により絞り込んで成形切断することが行われてきている（例えば特許文献１参照）。しかしながら、上述したパン生地等の発酵性の生地を外皮材として用いる場合筒状に形成することは外皮材に加圧、捻りなどが加わって生地がダメージを受けてしまい、成形切断後に生地が十分膨らまなくなり、外皮材が弾性のない硬い食品になってしまうため、その成形加工は人間の手で行っているのが現状である。こうした外皮材の筒状形成を避けてシート状の外皮材で食品成形を行う方法も提案されている。例えば、特許文献２では、丸形状生地片をベルトコンベアによりカップ上に供給し、その上に餡を配置して押込み棒でカップ内に押込み、封止ゲートによりパン生地を封止した点が記載されている。また、特許文献３では、シート状の食品生地をベルトコンベアで受け器上に搬送し、上方から押圧部材で生地を押圧して円形状に打ち抜いて凹状に形成して受け器内に設置される点が記載されている。また、特許文献４では、ほぼ扁平円形状に形成した外包材をベルトコンベアでカップ状の雌型の開口部に載置し、雌型の内壁面に沿って外包材を椀状に形成し、この椀状に形成した外包材の内部に内材を供給した後、外包材の上縁部を複数のシャッタ片から成るシャッタで絞ることによって外包材の上縁部を封着して内材を包み込んだ点が記載されている。

【発明が解決しようとする課題】
上述のようなシート状の外皮材を用いて成形を行う場合、内材を外皮材で包み込み成形する際に外皮材が適切な位置に配置されていないと外皮材の周縁部がきちんと封着されずに内材が露出してしまうことになる。上述した従来技術のように、外皮材の搬送は一般的にベルトコンベアで行っているが、ベルトコンベアから配置場所に移す際に外皮材が柔軟性を有するため外皮材の位置が一定にならないことが多い。こうした問題点に対して、従来技術では、外皮材を一旦カップ状の受け器等に保持して椀状形成を行うことで、外皮材を適切な位置に配置するようにしている。さらに、上述した特許文献３では、押圧部材で食品生地を円形に打ち抜いて受け器に設置するようにしている。他の先行文献では対応策について特に明記されてはいないが、カップ状の雌型等を用いていることから、外皮材を予めカップの開口部より大きめに形成しておき、外皮材の位置が少しずれても外皮材の周縁部が封着されるようにしているものと考えられる。しかしながら、適切な位置に外皮材が配置されたとしても外皮材の形状がばらついていると、外皮材の周縁部がきちんと封着されないおそれがある。また、特許文献２及び特許文献４では、外皮材の封着手段としてシャッタを用いているが、いずれもシャッタが摺動するカップの上面に外皮材の周縁部を保持しているため、シャッタの閉動作により外皮材の周縁部が水平方向に寝たまま圧縮されてうまく封着されない場合が生じやすい。
【０００５】
本発明は、従来の食品成形装置に上記のような難点があったことに鑑みて為されたもので、簡単な構成で外皮材の配置に柔軟に対応でき、確実に外皮材で内材を包み込み成形することができる食品成形装置を提供することを目的とするものである。
【０００６】
【課題を解決するための手段】
本発明に係る食品成形装置は、複数のシャッタ片を開閉動作させて開口部を形成するとともにシート状の外皮材を受けるシャッタと、外皮材に内材を配置する配置手段と、シャッタの開口部から下方にその中央部が湾曲形成された外皮材の周縁部を内材が包み込まれるように封着する封着手段と、シャッタの開口部から下方にその中央部が湾曲形成された外皮材を支持する支持手段とを備えた食品成形装置において、前記封着手段は、前記シャッタの上方に設けられるとともに、前記外皮材の周縁部に複数の接触面を接触させた状態で該接触面により前記外皮材の周縁部を寄せ集める手段を備えていることを特徴とする。
本発明に係る別の食品成形装置は、開口部が形成されるとともにシート状の外皮材を受ける受け部材と、外皮材に内材を配置する配置手段と、受け部材の開口部から下方にその中央部が湾曲形成された外皮材の周縁部を内材が包み込まれるように封着する封着手段と、受け部材の開口部から下方にその中央部が湾曲形成された外皮材を支持する支持手段とを備えた食品成形装置において、前記封着手段は、前記受け部材の上方に設けられるとともに、前記外皮材の周縁部に複数の接触面を接触させた状態で該接触面により前記外皮材の周縁部を寄せ集める手段を備えており、前記受け部材の下方には、寄せ集められた前記外皮材の周縁部に対して複数のシャッタ片を動作させて封着するシャッタを備えていることを特徴とする。
本発明に係るさらに別の食品成形装置は、開口部が形成されるとともにシート状の外皮材を受ける受け部材と、外皮材に内材を配置する配置手段と、受け部材の開口部から下方にその中央部が湾曲形成された外皮材の周縁部を内材が包み込まれるように封着する封着手段と、受け部材の開口部から下方にその中央部が湾曲形成された外皮材を支持する支持手段とを備えた食品成形装置において、前記封着手段は、前記受け部材の上方に設けられるとともに、前記外皮材の周縁部に複数の接触面を接触させた状態で該接触面により前記外皮材の周縁部を寄せ集める手段を備えており、前記受け部材の下方には、寄せ集められた前記外皮材の周縁部に対して複数のスライド封着部材を動作させて封着するスライド封着手段を備えていることを特徴とする。
さらに、上記の食品成形装置において、前記配置手段は、前記外皮材を前記受け部材の開口部に押し込んで前記外皮材を椀状に形成する押込み手段を備えたことを特徴とする。さらに、前記押込み手段は、前記内材を供給する内材供給手段を備えたことを特徴とする。さらに、前記外皮材の縁部を前記受け部材に保持する保持手段を備えたことを特徴とする。さらに、前記封着手段は、複数の封着部材の封着面を集合させて封着動作を行うことを特徴とする。さらに、複数の前記封着部材は、先端部に形成された封着面を前進させて封着動作を行うことを特徴とする。
【０００７】
上記のような構成を有することで、外皮材は受け手段に配置されて外皮材の中央部が受け手段の開口部から下方に湾曲形成された状態で封着手段による封着動作を行う際に、外皮材の周縁部に複数の接触面を接触させた状態で該接触面により外皮材の周縁部を寄せ集める手段を備えたことで、外皮材のダメージをできるだけ抑えて確実に外皮材により内材を包み込んで封着することができる。すなわち、受け手段に外皮材の周縁部が配置されることで、外皮材の周縁部がいわばせり上げられたような状態になり、確実な包み込みが可能になるとともに、外皮材の周縁部に複数の接触面を接触させてそのまま寄せ集めるようにしたので、外皮材の周縁部を接触面が摺動する等のダメージを極力抑えることができる。また、受け手段での外皮材の配置が多少ずれたとしても受け手段の開口部から外れなければ、外皮材の周縁部が封着手段の封着動作領域に配置されるため封着手段による封着動作には影響がなくなる。そして、支持手段が外皮材を支持するので、安定した封着動作ができる。
【０００８】
受け手段を開口部を形成した受け部材とすることで、外皮材を安定した状態で配置することができる。また、受け手段が複数のシャッタ片を開閉動作させて開口部を形成するシャッタを備えることで開口部の大きさを適宜設定できるとともに封着手段と兼ねることも可能となる。
【０００９】
また、受け部材の開口部で外皮材を椀状形成する場合内材を外皮材上に供給するだけでもその自重により椀状形成がなされるが、押込み手段を用いて積極的に椀状形成を行うこともできる。押込みの際同時に内材を供給するようにすればより生産効率を向上させることができる。また、受け部材の開口部から吸引手段により外皮材を吸引して椀状形成を行えば、外皮材を押圧することなく安定して外皮材を椀状形成することができ、外皮材に与えるダメージを軽減することができる。そして、外皮材の縁部を受け部材上に保持することで、より確実に外皮材の椀状形成及び封着動作を行うことができる。
【００１０】
また、封着手段が複数の封着部材の封着面を集合させて封着動作を行うことで外皮材へのダメージを抑えて封着させることができ、封着部材の先端部に封着面を形成して封着部材を前進させて封着動作を行うことで、適度な圧着力を外皮材に与えることができる。そして、封着動作の際に支持手段が下方に移動することで封着部材の圧着力とともに下方への引張り力が加わり、より確実に外皮材を封着することができる。なお、封着手段の外皮材を寄せ集める手段は、こうした複数の封着部材を用いて行うようにしてもよく、また、複数の封着部材と別に設けることもできる。
【００１１】
【発明の実施の形態】
以下、本発明を添付図面に示す実施形態に基づいて詳しく説明する。図１は本発明に係る食品成形装置の正面図であり、内部構造を示すために一部断面図としている。
【００１２】
図１において符号１で指示するものは、図２の平面図に示した４個の揺動封着部材10・10…で構成された封着手段である。揺動封着手段１は、図１及び図２に示すように、駆動軸11・11…に各々固定された各揺動封着部材10がこの駆動軸11を中心に往復揺動して各揺動封着部材10の先端に形成された封着面が封着点に集中するように構成されている。揺動封着部材10は、先端部が折れ曲がったＬ字状とされている。図１において符号２で指示するものは、図２の平面図に示した計４枚のシャッタ片20・20…が組み合って開閉可能に構成され、上述した揺動封着手段１の下方に配設されたシャッタ２である。シャッタ２の各シャッタ片20は、その上面が揺動封着手段１の揺動封着部材10の下面と隙間の無いように配設される。揺動封着手段１の駆動軸11と同心状に設けられた駆動中空軸21・21…に各シャッタ片20は固定されており、駆動中空軸21を中心に往復揺動して各シャッタ片20の先端が隣りのシャッタ片20の側辺を摺動移動するように構成されており、これらシャッタ片20・20…の側辺で囲んだ領域を開閉させる。
【００１３】
図４は図１の面Ｕにおける平面図で、揺動封着手段１の揺動駆動機構を示している。図１及び図４に示すように、揺動封着手段１の揺動駆動機構は、各駆動軸11の下端部に固定されたフランジ12と、このフランジ12に枢着され、フランジ12同士を連繋するリンク13・13…と、これらリンク13を駆動するモータ14とから構成されており、このモータ14の回転方向、回転角度等を制御することによって、複数のリンク13・13…が連関動作して揺動封着手段１の揺動封着部材10を適宜に封着点に集中させる。図３は図１の面Ｔにおける平面図で、シャッタ２の揺動駆動機構を示している。図１及び図３に示すように、シャッタ２の揺動駆動機構は、各駆動中空軸21の下端部に固定されたフランジ22と、このフランジ22に枢着され、フランジ22同士を連繋するリンク23・23…と、これらリンク23を駆動するモータ24とから構成されており、このモータ24の回転方向、回転角度等を制御することによって複数のリンク23・23…が連関動作してシャッタ２を適宜に開閉させる。
【００１４】
図１において符号３で指示するものは、外皮材を椀状に形成するための押込み手段である。本実施形態の押込み手段３は、図１に示すように、ステー31に固定された押込み部材30と、このステー31を上下動させる送りねじ機構32と、この送りねじ機構32を駆動するモータ33とから構成されており、このモータ33の回転方向、回転角度等を制御することによって押込み部材30を適宜に上下昇降させる。改めて詳述するが、この押込み部材30を下降させてシャッタ２の開口に進入させて、シャッタ２上に供給したシート状外皮材の中央部を窪ませて椀状に形成することができる。
【００１５】
また、本実施形態では、外皮材を椀状に形成すると共に椀状形成した外皮材の底部に内材を供給する内材供給手段を備えている。即ち、押込み部材30は、下端に内材を吐出するための吐出孔を備えた筒体により構成されており、この吐出孔を開閉するための弁40が内装されている。そして、ホッパ45内へ投入した内材を、従来公知のポンプ44により供給パイプ43を通じて押込み部材30の筒内へ圧送し、前記ステー31に固定されたエアシリンダ42の駆動によりロッド41を介して弁40を上下動させることで、吐出孔を適宜開閉して椀状形成した外皮材の底部に所要量の内材を供給する。
【００１６】
図１において符号５で指示するものは、外皮材の縁部をシャッタ２上に保持する保持手段である。保持手段５は、押込み部材30を囲むように設けられた複数の通孔を有するリング状のステー52、このステー52の通孔に上下スライド可能に挿嵌され、上端にステー52に係止可能な頭部を備えた複数の支持ロッド51、この支持ロッド51の下端に固定されるとともに押込み部材30を囲むように設けられたリング状の押え部材50、ステー52を上下動させるエアシリンダ53を備えている。押え部材50とステー52との間には、各支持ロッド51に被嵌され、押え部材50を下方へ付勢するためのコイルばねが設けられており、押え部材50が常時下方に付勢されるようになっている。したがって、エアシリンダ53によってステー52を下降させることで、押え部材50を受け部材２上の外皮材に押し付けることができる。
【００１７】
図１において符号６で指示するものは、シャッタ２の下方に配設され、外皮材を支持するための支持手段である。支持手段６は、図１に示すように、支持部材60と、この支持部材60によってベルトが上下動されるベルトコンベヤ63とから構成されている。支持部材60は、支持ロッド61を介してラック−ピニオン機構62に連結され、モータ64によりラック−ピニオン機構62が駆動されることで支持ロッド61を介して適宜に上下動して外皮材を支持する。そして、成形品Ｈはベルトコンベア63で次の工程へ搬送される。
【００１８】
図５〜図12を参照しながら本実施形態の食品成形装置による食品成形工程の一例について説明する。図５（ｂ）〜図12（ｂ）は、図１の部分断面図であり、各工程での揺動封着手段１、シャッタ２、押込み部材30、押え部材50及び支持部材60の配置を示している。図５（ａ）〜図12（ａ）は、それぞれ図５（ｂ）〜図12（ｂ）に示す各工程での揺動封着手段１及びシャッタ２の平面図を示している。なお、本実施形態では、外皮材Ｆとしてパン生地を使用し、内材Ｇとして餡を使用した例で説明する。
【００１９】
まず、図５（ａ）に示すように、揺動封着手段１の封着部材１０を封着点から退避させ、シャッタ２を閉鎖させた状態におき、図５（ｂ）のように押込み部材30を上昇させた状態でシャッタ２のシャッタ片20上にシート状の外皮材Ｆを戴置する。本実施形態では、外皮材Ｆをシャッタ片20上に安定的に戴置するため、シャッタ２を全閉させた状態で外皮材Ｆを載置しているが、シャッタ２を外皮材Ｆが落下しない程度に開口させた状態で外皮材Ｆを載置するようにしても良い。また、シャッタ片20上に外皮材Ｆを戴置した後、揺動封着手段１の揺動封着部材10を封着点に向けて前進させて、外皮材Ｆが所定位置に収まるように外皮材Ｆの位置調整を行なうようにしてもよい。
【００２０】
次に、図６（ａ）に示すように、押込み部材30が通過できる程度にシャッタ２を開口させる。そして、図６（ｂ）のように、押込み部材30を下降させると、押込み部材30に装着された押え部材50が外皮材Ｆの周縁部に当接する。引き続き、押込み部材30を下降させると、押え部材50は、支持ロッド51に固定されているため、押込み部材30に固定されたステー52との間隔が狭まる。間隔が狭まることでコイルばね５３の付勢力が働き、押え部材50は外皮材Ｆの周縁部に押し付けられて外皮材Ｆがシャッタ２のシャッタ片20上に保持される。このように外皮材Ｆの周縁部を保持した状態で、図７（ｂ）に示すように、押込み部材30をシャッタ２の開口部にさらに進入させて外皮材Ｆの中央部を窪ませることにより外皮材Ｆを椀状に形成する。このとき、外皮材Ｆを支持部材60で支持するようにすれば、外皮材が必要以上に下方へ伸びてしまうことを防ぐことができ、外皮材を確実に椀状形成することができる。
【００２１】
次に、図８（ｂ）に示すように、押込み部材30を上昇させながら押込み部材30内の弁40を上昇させて吐出孔を開くことにより、内材Ｇが吐出されて椀状形成された外皮材Ｆの底部に配置される。所定量の内材Ｇが吐出された時点で弁40を下降させ吐出孔を閉じる。このように本実施形態では、押込み部材30を上昇させると同時にこの押込み部材30を通して内材Ｇを供給しているので、押込み部材30の上昇に伴ってパン生地から成る外皮材Ｆが収縮してしまうのを防ぐことができるとともに、外皮材の形状形成と内材の供給を効率よく行うことができる。また、このとき、外皮材Ｆを支持部材60で支持しているので、内材Ｇの吐出による外皮材の必要以上の伸びを防ぐことができ、内材Ｇを確実に配置することができる。さらに押込み部材30を上昇させて、図９（ｂ）に示すように、押え部材50を外皮材Ｆの周縁部から離す。
【００２２】
次に、図10（ａ）及び図11（ａ）に示すように、揺動封着手段１の揺動封着部材10を封着点に向けて前進させて、シャッタ２のシャッタ片20上に位置する外皮材Ｆの周縁部を揺動封着部材10の先端の封着面により封着点に寄せ集め、外皮材Ｆで内材Ｇを包むようにする（図10（ｂ）及び図11（ｂ）参照）。この際、揺動封着手段１の各揺動封着部材10の封着面は当接した状態にはならず、外皮材Ｆの周縁部が寄せ集められて内材Ｇを覆い隠すように、所定間隔だけ空いた状態で前進動作を停止する。すなわち、従来では、人間の手によって外皮材で内材を包み込む場合に、周縁部を寄せ集め指で摘み上げるようにしているが、こうした動作と類似の動作を揺動封着手段１の各揺動封着部材10が行っているといえる。また、この工程では、複数のシャッタ片10・10…によって外皮材Ｆの周縁部を内材Ｇに沿って中央に集めることができるので、外皮材Ｆと内材Ｇとの間の空気を逃がしながら外皮材Ｆで内材Ｇを包んでゆくことができる。
【００２３】
そして、図12（ａ）に示すように、揺動封着手段１で外皮材Ｆの周縁部を集めてシャッタ２を動作させることにより、集めた外皮材Ｆの周縁部を確実に封着して外皮材Ｆで内材Ｇを包み込んだ成形品Ｈを得るのである（図12（ｂ）参照）。この際にも、シャッタ２は完全に閉じることなく、外皮材Ｆの封着が十分行われたところで閉じる動作を停止する。したがって、外皮材Ｆは、分割又は切断されることがないため、滓等は発生することがないだけでなく、外皮材Ｆのダメージも軽減される。その後、成形品Ｈを支える支持部材60が下降してベルト上に成形品Ｈが載置された状態となり、ベルトコンベア63を駆動して成形品Ｈをベルト搬送する。なお、外皮材Ｆの周縁部をシャッタ２で封着するとき、支持部材60を適宜に上下動させてシャッタ２との間隔を調整することでシャッタ２による外皮材Ｆの絞込み程度を調整でき、外皮材Ｆの封着の度合いを見ながら調整すればより確実に封着することができる。図13に成形品Ｈの斜視図（図13（ａ））及び側面断面図（図13（ｂ））を示す。成形品Ｈには、上面中央に突起部Ｃが形成されており、その根元は第二シャッタの動作により確実に封着されている。成形品Ｈは、図１でも説明したように、突起部Ｃは押し潰されるとともに、反転して上面は突起部のない状態となって、見栄えのよいものとなる。
【００２４】
このように本実施形態によれば、まず、揺動封着手段１が外皮材Ｆの周縁部を集め（図11（ｂ）の符号Ａ参照）、次いで下方のシャッタ２が、集めた部分（図11（ｂ）の符号Ａ参照）とは異なる外皮材Ｆの周辺部分（図11（ｂ）の符号Ｂ参照）を更に集めて封着するので、外皮材Ｆの形状にばらつきがあったとしても、外皮材の周縁部を確実に封着することができる。また、揺動封着手段１及びシャッタ２はともに完全に閉じた状態にはならないため、外皮材は分離することなく、滓等の発生も防止できる。
【００２５】
さらに、図14及び図15に示すように、揺動封着手段１とシャッタ２との間に、外皮材Ｆを受ける受け部材として薄板70を挟んでおくと、押え部材50と薄板70により外皮材Ｆを確実に保持できる。薄板70には、図16の平面図に示すような円形の開口部71が設けられており、開口部71に上記実施形態のように押込み部材30を進入させて外皮材を椀状形成する。
【００２６】
図17には、支持部材60に関する別の例を示している。この例では、支持部材60は回転軸64により外皮材Ｆを載置する面が回転するようになっており、載置面には、回転中心から放射状に延びるように段差部65が形成されている。そして、外皮材Ｆが載置されて揺動封着手段１及びシャッタ２により封着動作が行われる際に載置面を回転させて外皮材Ｆの封着部分に所定の捻れを加えることで、外皮材Ｆがより確実に封着される。
【００２７】
上記実施形態では、封着手段として、揺動封着手段１及びシャッタ２を用いているが、封着手段としては、これらに限定されない。例えば、図18に示すように、棒状のスライド封着部材80を備えたスライド封着手段８を用いてもよい。スライド封着部材80は、ドーナツ状の基台81に穿設された貫通孔に摺動自在に挿通されており、各スライド封着部材80が基台81の中心に向かって前進して封着点にその先端が集中するようになっている。そして、貫通孔内には、バネが装着されており、このバネは、スライド封着部材80を退避させる方向に付勢するように作用する。基台81の周囲には、基台81を囲むようにドーナツ状の回転体82が回動自在に配設されており、その外周面には駆動歯車85と噛み合う歯列83が形成され、内周面にはスライド封着部材80の後端と当接するカム面84が形成されている。したがって、駆動歯車85により回転体82を回動させると、カム面84が回動してスライド封着部材80の後端を押圧し、それによってスライド封着部材80が前進及び退避動作を行う。
【００２８】
図19から図24は、封着手段として、揺動封着手段１及びスライド封着手段８を用いた例を示している。図６（ｂ）〜図12（ｂ）と同様の部分断面図であり、各工程での押込み部材30、押え部材50及び支持部材60についても同様のものを用いている。揺動封着手段１とスライド封着手段８との間には、外皮材Ｆの受け部材として薄板70が配設されている。
【００２９】
図19では、揺動封着手段１及びスライド封着手段８はともに退避位置にあり、薄板70にシート状の外皮材Ｆが供給される。そして、図20に示すように、押し込み部材30が下降して外皮材Ｆの周縁部を押え部材50で薄板７０に保持すると共に薄板70の開口部71に進入して外皮材Ｆが椀状に形成される。下方から支持部材60が外皮材Ｆを支持する。スライド封着部材80は、退避位置から前進して待機位置に停止する。次に、図21に示すように、押し込み部材30から内材Ｇが椀状形成された外皮材Ｆに供給された後、押し込み部材30は上昇する（図22参照）。そして、揺動封着手段１の各揺動封着部材10が前進して薄板70上に保持されていた外皮材Ｆの周縁部を封着点に寄せ集め（図23参照）、続いてスライド封着手段８の各スライド封着部材80が前進して各揺動封着部材10とともに封着動作を行う（図24参照）。
【００３０】
この例においても、揺動封着手段１が外皮材Ｆの周縁部を集め（図23の符号Ａ参照）、次いで下方のスライド封着手段８が、集めた部分（図24の符号Ａ参照）とは異なる外皮材Ｆの周辺部分（図24の符号Ｂ参照）を更に集めて封着するので、外皮材Ｆの形状にばらつきがあったとしても、外皮材Ｆの周縁部を確実に封着することができる。
【００３１】
上述した例以外にも、例えば、図25及び図26に示すように、２つのスライド封着手段８ａ、８ｂを用いて封着動作を行うようにしてもよい。この場合も、上方のスライド封着手段８ａが外皮材Ｆの周縁部を集め（図25の符号Ａ参照）、次いで下方のスライド封着手段８ｂが、集めた部分（図26の符号Ａ参照）とは異なる外皮材Ｆの周辺部分（図2６の符号Ｂ参照）を更に集めて封着するので、外皮材Ｆの周縁部を確実に封着することができる。図27から図29では、さらに、別の封着手段を用いた例を示している。挟持封着手段９は、押し込み手段３の上方に装着されており、封着点を中心として複数の爪部材90を備えている。複数の爪部材90は下方に伸びる先端部91が封着点に集中して封着動作を行うようになっている。各爪部材90の上方に伸びる後端部92はＬ字状に折れ曲がるように形成されており、後端は押し込み手段３に固定された支持部材93にピン94で回動自在に取付けられている。そして、折れ曲がり部分には連設部材96の下端がピン97により回動自在に取付けられており、連設部材96の上端は、駆動部材95にピン98で回動自在に取付けられている。
【００３２】
図27に示すように、挟持封着手段９は、シャッタ２上に配設された薄板70の上面に爪部材90の先端が当接するように配置されており、各爪部材90は開いた状態となっている。そして、上記実施形態と同様に押し込み手段３により外皮材Ｆが椀状形成されて内材Ｇが供給される。図28では、駆動部材95が図示しない駆動手段により下方に移動し、それに伴い連設部材96が爪部材90の折れ曲がり部分を下方に押圧することで、爪部材90はピン94を中心に内側に回動する。したがって、各爪部材90の先端部91が封着点に向かって集中するように移動し、その際に薄板70上に保持されていた外皮材Ｆの周縁部を寄せ集めるように動作する。図29では、各爪部材90により外皮材Ｆの周縁部を寄せ集めた状態でシャッタ２を動作させて封着動作を行う。
【００３３】
また、上述した実施形態では外皮材Ｆを押込み部材30により椀状形成しているが、押込み部材30の代わりに支持部材に吸引手段を設けることで椀状形成することもできる。図30から図33にその食品成形工程を示す。図30に示すように、保持手段５のステー52はシリンダ54に固定され、シリンダ54の進退動作に応じて保持手段５は上下動する。支持部材100は先端に複数の通気孔101を設けた管状部材102で構成され、管状部材102には図示されていない吸排気装置に接続されている。そして、支持部材100は、通気孔101から吸気することで外皮材Ｆを吸着保持するとともに通気孔101から排気することで吸着保持した外皮材Ｆを離すようになる。図30では、揺動封着手段１が退避位置に設定され、シャッタ２は閉じた状態に設定されており、シャッタ２の上面に内材Ｇを配置した外皮材Ｆが供給される。図31では、シャッタ２を開いた状態にした後保持手段５が下降して外皮材Ｆの周縁部をシャッタ２の上面に押え付ける。支持部材100が上方に移動して外皮材Ｆの下面に当接し、通気孔101から吸気することで外皮材Ｆを吸着保持する。図32では、支持部材100が外皮材Ｆを吸着保持した状態で下降することで外皮材Ｆが椀状に形成される。以後上述した実施形態と同様に、保持手段５が上昇して退避して、揺動封着手段１の揺動封着部材10が動作を開始し、その先端部が外皮材Ｆの周縁部を寄せ集める。そして、揺動封着手段１が外皮材Ｆの周縁部を寄せ集めた状態で、シャッタ２が動作開始してさらに外皮材Ｆの周縁部を寄せ集めながら封着動作を行う。
【００３４】
なお、上述した例では、押え部材50により外皮材Ｆを受け部材２上に保持するようにしているが、外皮材Ｆが椀状形成の際に受け部材70からずれないようであれば、保持手段を設けなくてもかまわない。
【００３５】
また、各封着手段の封着部材の数は、特に限定されることはなく、必要に応じて設定すればよい。さらに、こうした封着手段を複数組並列配置して同時に駆動することで、生産効率が大幅にアップするとともに、駆動軸の共通化等により装置の構造が単純化でき、さらにコンパクト化も達成できる。
【００３６】
また、上述した例において、上方に配置された揺動封着手段１、スライド封着手段８及び挟持封着手段９については、封着動作まで行うようにされているが、外皮材の周縁部を寄せ集めるまでを行い、その後下方に配置されたシャッタ２及びスライド封着手段８により封着するようにしてもよい。
【００３７】
【発明の効果】
以上に説明したとおり、本発明に係る食品成形装置にあっては、外皮材は受け手段に配置されて外皮材の中央部が受け手段の開口部から下方に湾曲形成された状態で封着手段による封着動作を行うことから、確実に外皮材により内材を包み込んで封着することができる。すなわち、受け手段に外皮材の周縁部が配置されることで、外皮材の周縁部がいわばせり上げられたような状態になり、確実な包み込みが可能になる。また、受け手段での外皮材の配置が多少ずれたとしても受け手段の開口部から外れなければ、外皮材の周縁部が封着手段の封着動作領域に配置されるため封着手段による封着動作には影響がなくなる。そして、支持手段が外皮材を支持するので、安定した封着動作ができる。
【００３８】
受け手段を開口部を形成した受け部材とすることで、外皮材を安定した状態で配置することができる。また、受け手段が複数のシャッタ片を開閉動作させて開口部を形成するシャッタを備えることで開口部の大きさを適宜設定できるとともに封着手段と兼ねることも可能となる。さらに、受け手段に外皮材の位置を調整する位置決め手段を設けることで、外皮材の位置を確実に適切な位置に配置することができ、より確実にシャッタによる封着動作を行うことができる。
【００３９】
また、受け部材の開口部で外皮材を椀状形成する場合内材を外皮材上に供給するだけでもその自重により椀状形成がなされるが、押込み手段を用いて積極的に椀状形成を行うこともできる。押込みの際同時に内材を供給するようにすればより生産効率を向上させることができる。また、受け部材の開口部から吸引手段により外皮材を吸引して椀状形成を行えば、外皮材を押圧することなく安定して外皮材を椀状形成することができ、外皮材に与えるダメージを軽減することができる。そして、外皮材の縁部を受け部材上に保持することで、より確実に外皮材の椀状形成及び封着動作を行うことができる。
【００４０】
また、封着手段が複数の封着部材の封着面を集合させて封着動作を行うことで外皮材へのダメージを抑えて封着させることができ、封着部材の先端部に封着面を形成して封着部材を前進させて封着動作を行うことで、適度な圧着力を外皮材に与えることができる。そして、封着動作の際に支持手段が下方に移動することで封着部材の圧着力とともに下方への引張り力が加わり、より確実に外皮材を封着することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a food molding apparatus, and more particularly to a food molding apparatus capable of reliably wrapping and molding inner materials such as rice cakes, cooked meat and vegetables with outer skin materials such as bread dough and bun dough.
[0002]
[Prior art]
As a technology related to food molding that wraps the inner material with the outer shell material, conventionally, the inner material is made into a rod shape and the outer shell material is continuously formed on the outside, and then formed by narrowing down by the opening and closing operation of the shutter mechanism. Cutting has been performed (see, for example, Patent Document 1). However, when fermentable dough such as the bread dough described above is used as a shell material, forming it into a cylindrical shape causes the dough to be damaged due to pressure, twisting, etc. applied to the skin material, and the dough swells sufficiently after forming and cutting. Since the outer skin becomes a hard food with no elasticity, the molding process is currently performed by human hands. There has also been proposed a method of forming food with a sheet-like skin material while avoiding the tubular formation of the skin material. For example, Patent Document 2 describes that a round dough piece is supplied onto a cup by a belt conveyor, a ridge is placed thereon, pushed into the cup with a push bar, and the bread dough is sealed with a sealing gate. ing. Moreover, in patent document 3, a sheet-like food dough is conveyed on a receiver with a belt conveyor, the dough is pressed from above by a pressing member, punched into a circular shape, and formed into a concave shape and installed in the receiver. Points are listed. In Patent Document 4, the outer packaging material formed in a substantially flat circular shape is placed on the opening of the cup-shaped female mold by a belt conveyor, and the outer packaging material is formed in a bowl shape along the inner wall surface of the female mold. After supplying the inner material to the inside of the outer packaging material formed in this bowl shape, the upper edge of the outer packaging material is squeezed with a shutter composed of a plurality of shutter pieces to seal the upper edge of the outer packaging material. The encased point is indicated.

[Problems to be solved by the invention]
When molding using a sheet-like skin material as described above, when the inner material is wrapped and molded with the outer skin material, the outer edge of the outer skin material is properly sealed unless the outer skin material is arranged at an appropriate position. Without this, the inner material will be exposed. As in the prior art described above, the outer shell material is generally transported by a belt conveyor, but the outer shell material is flexible when moving from the belt conveyor to the place of placement, so that the position of the outer shell material is not constant. There are many. With respect to such problems, in the conventional technology, the outer skin material is temporarily held in a cup-shaped receptacle or the like to form a hook shape, thereby arranging the outer skin material at an appropriate position. Furthermore, in patent document 3 mentioned above, food dough is punched out circularly with a press member, and it is made to install in a receiver. In other prior literatures, the countermeasures are not specified in particular, but since a cup-shaped female mold or the like is used, the skin material is previously formed larger than the opening of the cup, and the position of the skin material is It is considered that the peripheral edge of the outer skin material is sealed even if it is slightly shifted. However, even if the skin material is arranged at an appropriate position, if the shape of the skin material varies, the peripheral edge of the skin material may not be properly sealed. Further, in Patent Document 2 and Patent Document 4, a shutter is used as a sealing means for the outer skin material, but since both hold the peripheral edge portion of the outer skin material on the upper surface of the cup on which the shutter slides, Due to the closing operation, the peripheral portion of the outer skin material is likely to be compressed while being laid down in the horizontal direction and not sealed well.
[0005]
The present invention was made in view of the above-mentioned difficulties in the conventional food molding apparatus, and can be flexibly adapted to the arrangement of the outer skin material with a simple configuration, and the inner material can be reliably used by the outer skin material. It is an object of the present invention to provide a food molding apparatus capable of wrapping molding.
[0006]

  Another food molding apparatus according to the present invention is:A receiving member for receiving a sheet-like outer shell material with an opening formed therein, a disposing means for arranging the inner material in the outer skin material, and a peripheral edge of the outer skin material having a central portion bent downward from the opening of the receiving member In a food molding apparatus comprising: sealing means for sealing the portion so that the inner material is wrapped; and support means for supporting the outer skin material whose central portion is curved downward from the opening of the receiving member, The sealing means is provided above the receiving member, and includes means for gathering the peripheral edge portions of the outer skin material by the contact surfaces in a state where a plurality of contact surfaces are in contact with the peripheral edge portions of the outer skin material. A shutter is provided below the receiving member to operate and seal a plurality of shutter pieces with respect to the peripheral portion of the collected skin material.
  Yet another food molding apparatus according to the present invention is:A receiving member for receiving a sheet-like outer shell material with an opening formed therein, a disposing means for arranging the inner material in the outer skin material, and a peripheral edge of the outer skin material having a central portion bent downward from the opening of the receiving member In a food molding apparatus comprising: sealing means for sealing the portion so that the inner material is wrapped; and support means for supporting the outer skin material whose central portion is curved downward from the opening of the receiving member, The sealing means is provided above the receiving member, and includes means for gathering the peripheral edge portions of the outer skin material by the contact surfaces in a state where a plurality of contact surfaces are in contact with the peripheral edge portions of the outer skin material. A slide sealing means for operating and sealing a plurality of slide sealing members with respect to the peripheral edge of the collected outer skin material is provided below the receiving member.
  Furthermore, in the food molding apparatus, the arrangement means receives the outer skin material.ElementAnd a pressing means for forming the outer skin material into a bowl shape. Further, the pushing means includes an inner material supply means for supplying the inner material. Further, the edge of the outer skin material is received by the receiver.ElementIt is characterized by having holding means for holding. Furthermore, the sealing means collects sealing surfaces of a plurality of sealing members and performs a sealing operation. Further, the plurality of sealing members perform a sealing operation by advancing a sealing surface formed at a tip portion.
[0007]
By having the configuration as described above, the outer covering material is disposed on the receiving means, and when the sealing means performs the sealing operation with the central portion of the outer covering material curved downward from the opening of the receiving means. In addition, by providing means for gathering the peripheral edge of the outer skin material by the contact surface in a state where a plurality of contact surfaces are in contact with the peripheral edge of the outer skin material, The material can be wrapped and sealed. That is, by arranging the peripheral portion of the outer skin material on the receiving means, the peripheral portion of the outer skin material is in a state of being raised, so that it can be securely wrapped and a plurality of peripheral edges of the outer skin material are provided. Since the contact surfaces are brought into contact and gathered together, damage such as sliding of the contact surface on the peripheral edge of the outer skin material can be suppressed as much as possible. Further, even if the arrangement of the outer covering material at the receiving means is slightly deviated, if the outer covering material does not come out of the opening of the receiving means, the peripheral edge of the outer covering material is arranged in the sealing operation area of the sealing means, so that sealing by the sealing means is performed. There is no effect on the wearing operation. And since the support means supports the outer skin material, a stable sealing operation can be performed.
[0008]
By making the receiving means a receiving member having an opening, the outer skin material can be arranged in a stable state. In addition, since the receiving means includes a shutter that opens and closes a plurality of shutter pieces to form an opening, the size of the opening can be set as appropriate and can also serve as a sealing means.
[0009]
In addition, when the outer shell material is formed in a hook shape at the opening of the receiving member, the hook material is formed by its own weight only by supplying the inner material onto the outer shell material. It can also be done. If the inner material is supplied at the same time as pressing, the production efficiency can be further improved. Further, if the outer skin material is sucked from the opening of the receiving member by suction means to form a hook shape, the outer skin material can be stably formed into a hook shape without pressing the outer skin material, and damage to the outer skin material Can be reduced. Then, by holding the edge portion of the outer skin material on the receiving member, it is possible to more reliably perform the hook-like formation and sealing operation of the outer skin material.
[0010]
In addition, the sealing means collects the sealing surfaces of a plurality of sealing members and performs a sealing operation so that the sealing material can be sealed while suppressing damage to the outer skin material, and is sealed to the front end of the sealing member. By forming the surface and advancing the sealing member to perform the sealing operation, an appropriate pressure-bonding force can be applied to the outer skin material. Then, when the supporting means moves downward during the sealing operation, a downward pulling force is applied together with the pressing force of the sealing member, so that the outer skin material can be more reliably sealed. The means for gathering the outer cover material of the sealing means may be performed using such a plurality of sealing members, or may be provided separately from the plurality of sealing members.

[0018]
With reference to FIGS. 5 to 12, an example of a food molding process by the food molding apparatus of the present embodiment will be described. 5 (b) to 12 (b) are partial cross-sectional views of FIG. 1, and the arrangement of the swing sealing means 1, the shutter 2, the pushing member 30, the pressing member 50, and the supporting member 60 in each step is shown. Show. 5 (a) to 12 (a) are plan views of the swing sealing means 1 and the shutter 2 in the respective steps shown in FIGS. 5 (b) to 12 (b), respectively. In the present embodiment, an example in which bread dough is used as the skin material F and rice cake is used as the inner material G will be described.
[0019]
First, as shown in FIG. 5 (a), the sealing member 10 of the swinging sealing means 1 is retracted from the sealing point, the shutter 2 is closed, and pushed in as shown in FIG. 5 (b). A sheet-like outer skin material F is placed on the shutter piece 20 of the shutter 2 with the member 30 raised. In this embodiment, in order to stably place the skin material F on the shutter piece 20, the skin material F is placed with the shutter 2 fully closed, but the skin material F falls on the shutter 2. The outer skin material F may be placed in a state where it is opened to the extent that it does not. Further, after the outer skin material F is placed on the shutter piece 20, the rocking sealing member 10 of the rocking sealing means 1 is advanced toward the sealing point so that the outer skin material F is placed in a predetermined position. The position of the outer skin material F may be adjusted.
[0020]
Next, as shown in FIG. 6A, the shutter 2 is opened to such an extent that the pushing member 30 can pass through. Then, as shown in FIG. 6B, when the pushing member 30 is lowered, the holding member 50 attached to the pushing member 30 comes into contact with the peripheral portion of the outer skin material F. Subsequently, when the pushing member 30 is lowered, the holding member 50 is fixed to the support rod 51, so that the distance from the stay 52 fixed to the pushing member 30 is reduced. The urging force of the coil spring 53 works by the narrowing of the interval, and the pressing member 50 is pressed against the peripheral edge of the outer skin material F, and the outer skin material F is held on the shutter piece 20 of the shutter 2. With the peripheral edge portion of the outer skin material F held in this way, as shown in FIG. 7B, the pushing member 30 is further advanced into the opening of the shutter 2 and the central portion of the outer skin material F is depressed. The outer skin material F is formed in a bowl shape. At this time, if the outer skin material F is supported by the support member 60, it is possible to prevent the outer skin material from extending downward more than necessary, and the outer skin material can be surely formed into a bowl shape.
[0021]
Next, as shown in FIG. 8 (b), the inner member G is discharged to form a bowl by opening the discharge hole by raising the valve 40 in the pushing member 30 while raising the pushing member 30. Arranged at the bottom of the skin material F. When a predetermined amount of the inner material G is discharged, the valve 40 is lowered to close the discharge hole. Thus, in this embodiment, since the pushing member 30 is raised and the inner material G is supplied through the pushing member 30, the outer skin material F made of bread dough contracts as the pushing member 30 rises. In addition, it is possible to efficiently form the outer skin material and supply the inner material. At this time, since the outer skin material F is supported by the support member 60, it is possible to prevent the outer skin material from being stretched more than necessary due to the discharge of the inner material G, and the inner material G can be reliably disposed. Further, the pressing member 30 is raised, and the pressing member 50 is separated from the peripheral portion of the outer skin material F as shown in FIG.
[0022]
Next, as shown in FIGS. 10 (a) and 11 (a), the rocking sealing member 10 of the rocking sealing means 1 is moved forward toward the sealing point, and the shutter piece 20 of the shutter 2 is moved over. The peripheral portion of the outer skin material F located at the position is gathered to the sealing point by the sealing surface at the tip of the rocking sealing member 10, and the inner material G is wrapped with the outer skin material F (FIGS. 10B and 11). (See (b)). At this time, the sealing surfaces of the oscillating sealing members 10 of the oscillating sealing means 1 are not in contact with each other, and the peripheral portions of the outer skin material F are gathered together so as to cover the inner material G. The forward movement is stopped with a predetermined interval. That is, conventionally, when the inner material is wrapped with the outer skin material by a human hand, the peripheral portions are gathered together and picked up by the fingers. It can be said that the dynamic sealing member 10 is performing. Further, in this step, since the peripheral portion of the outer skin material F can be gathered in the center along the inner material G by the plurality of shutter pieces 10, 10..., The air between the outer skin material F and the inner material G is released. However, the inner material G can be wrapped with the outer skin material F.
[0023]
Then, as shown in FIG. 12 (a), the peripheral portion of the outer skin material F is collected by the swinging sealing means 1 and the shutter 2 is operated, so that the peripheral portion of the collected outer skin material F is securely sealed. Thus, the molded product H in which the inner material G is wrapped with the outer skin material F is obtained (see FIG. 12B). Also at this time, the shutter 2 is not completely closed, and the closing operation is stopped when the outer skin material F is sufficiently sealed. Therefore, since the outer skin material F is not divided or cut, not only wrinkles are generated but also damage to the outer skin material F is reduced. Thereafter, the support member 60 that supports the molded product H is lowered and the molded product H is placed on the belt, and the belt conveyor 63 is driven to convey the molded product H to the belt. In addition, when sealing the peripheral part of the outer skin material F with the shutter 2, the degree of narrowing down of the outer skin material F by the shutter 2 can be adjusted by adjusting the distance from the shutter 2 by appropriately moving the support member 60 up and down. If the adjustment is made while observing the degree of sealing of the outer skin material F, sealing can be performed more reliably. FIG. 13 shows a perspective view (FIG. 13 (a)) and a side sectional view (FIG. 13 (b)) of the molded product H. FIG. A protrusion C is formed at the center of the upper surface of the molded product H, and its root is securely sealed by the operation of the second shutter. As described with reference to FIG. 1, the molded product H is squeezed and turned upside down, so that the upper surface has no projections, so that it looks good.
[0024]
Thus, according to the present embodiment, first, the swing sealing means 1 collects the peripheral edge portion of the outer skin material F (see symbol A in FIG. 11B), and then the lower shutter 2 collects the portion ( Since the peripheral portion of the outer skin material F (see the reference symbol B in FIG. 11B) different from the reference symbol A in FIG. 11B is further collected and sealed, the shape of the outer skin material F is assumed to vary. In addition, the peripheral edge of the outer skin material can be reliably sealed. In addition, since the swing sealing means 1 and the shutter 2 are not completely closed, the outer skin material is not separated, and generation of wrinkles can be prevented.
[0025]
Further, as shown in FIGS. 14 and 15, when a thin plate 70 is sandwiched between the swinging sealing means 1 and the shutter 2 as a receiving member for receiving the outer skin material F, the pressing member 50 and the thin plate 70 make the outer skin. The material F can be securely held. The thin plate 70 is provided with a circular opening 71 as shown in the plan view of FIG. 16, and the pushing member 30 is made to enter the opening 71 as in the above-described embodiment, so that the outer skin material is formed in a bowl shape.
[0026]
FIG. 17 shows another example relating to the support member 60. In this example, the support member 60 is configured such that a surface on which the outer skin material F is placed is rotated by a rotation shaft 64, and a stepped portion 65 is formed on the placement surface so as to extend radially from the rotation center. Yes. Then, when the outer skin material F is placed and the sealing operation is performed by the swing sealing means 1 and the shutter 2, the placement surface is rotated to apply a predetermined twist to the sealing portion of the outer skin material F. The outer skin material F is more reliably sealed.
[0027]
In the above embodiment, the swing sealing means 1 and the shutter 2 are used as the sealing means, but the sealing means is not limited to these. For example, as shown in FIG. 18, a slide sealing means 8 having a rod-like slide sealing member 80 may be used. The slide sealing member 80 is slidably inserted into a through-hole formed in the donut-shaped base 81, and each slide sealing member 80 advances toward the center of the base 81 and seals. The tip is concentrated at the point. A spring is mounted in the through-hole, and this spring acts to urge the slide sealing member 80 in the retracting direction. Around the base 81, a donut-shaped rotating body 82 is rotatably disposed so as to surround the base 81, and a tooth row 83 meshing with the drive gear 85 is formed on the outer peripheral surface thereof. A cam surface 84 that contacts the rear end of the slide sealing member 80 is formed on the peripheral surface. Therefore, when the rotating body 82 is rotated by the drive gear 85, the cam surface 84 rotates and presses the rear end of the slide sealing member 80, whereby the slide sealing member 80 advances and retracts.
[0028]
19 to 24 show an example in which the swing sealing means 1 and the slide sealing means 8 are used as the sealing means. FIG. 13B is a partial cross-sectional view similar to FIG. 6B to FIG. 12B, and the same members are used for the pressing member 30, the pressing member 50 and the supporting member 60 in each step. Between the swing sealing means 1 and the slide sealing means 8, a thin plate 70 is disposed as a receiving member for the outer skin material F.
[0029]
In FIG. 19, the swing sealing means 1 and the slide sealing means 8 are both in the retracted position, and the sheet-like skin material F is supplied to the thin plate 70. Then, as shown in FIG. 20, the push-in member 30 descends and the peripheral portion of the outer skin material F is held on the thin plate 70 by the pressing member 50 and enters the opening 71 of the thin plate 70 so that the outer skin material F becomes bowl-shaped. It is formed. The support member 60 supports the outer skin material F from below. The slide sealing member 80 advances from the retracted position and stops at the standby position. Next, as shown in FIG. 21, after the inner member G is supplied from the pushing member 30 to the outer skin material F formed in a bowl shape, the pushing member 30 rises (see FIG. 22). Then, each rocking sealing member 10 of the rocking sealing means 1 moves forward and gathers the peripheral edge portions of the skin material F held on the thin plate 70 to the sealing point (see FIG. 23), and then slides. Each slide sealing member 80 of the sealing means 8 moves forward and performs a sealing operation together with each swing sealing member 10 (see FIG. 24).
[0030]
Also in this example, the rocking sealing means 1 collects the peripheral portion of the outer skin material F (see symbol A in FIG. 23), and the lower slide sealing means 8 then collects the portion (see symbol A in FIG. 24). Since the peripheral portion of the outer skin material F (see reference numeral B in FIG. 24) is further collected and sealed, even if the shape of the outer skin material F varies, the peripheral edge portion of the outer skin material F is securely sealed. can do.
[0031]
In addition to the example described above, for example, as shown in FIGS. 25 and 26, the sealing operation may be performed using two slide sealing means 8a and 8b. Also in this case, the upper slide sealing means 8a collects the peripheral edge portion of the outer skin material F (see symbol A in FIG. 25), and the lower slide sealing means 8b then collects the portion (see symbol A in FIG. 26). Since the peripheral portion of the outer skin material F different from that (see reference numeral B in FIG. 26) is further collected and sealed, the peripheral edge portion of the outer skin material F can be reliably sealed. 27 to 29 show an example in which another sealing means is used. The clamping and sealing means 9 is mounted above the pushing means 3 and includes a plurality of claw members 90 around the sealing point. The plurality of claw members 90 are configured to perform a sealing operation with the tip portions 91 extending downward concentrated on the sealing points. A rear end portion 92 extending upward of each claw member 90 is formed to be bent in an L shape, and the rear end is rotatably attached to a support member 93 fixed to the pushing means 3 by a pin 94. . The lower end of the connecting member 96 is rotatably attached to the bent portion by a pin 97, and the upper end of the connecting member 96 is rotatably attached to the drive member 95 by a pin 98.
[0032]
As shown in FIG. 27, the clamping / sealing means 9 is arranged so that the tip of the claw member 90 abuts on the upper surface of the thin plate 70 disposed on the shutter 2, and each claw member 90 is in an open state. It has become. And the outer skin material F is formed in the hook shape by the pushing means 3 similarly to the said embodiment, and the inner material G is supplied. In FIG. 28, the driving member 95 is moved downward by driving means (not shown), and accordingly, the connecting member 96 presses the bent portion of the claw member 90 downward, so that the claw member 90 is inwardly centered on the pin 94. Rotate. Therefore, the tip 91 of each claw member 90 moves so as to concentrate toward the sealing point, and operates so as to gather the peripheral portions of the skin material F held on the thin plate 70 at that time. In FIG. 29, the sealing operation is performed by operating the shutter 2 with the claw members 90 gathering the peripheral portions of the outer skin material F together.
[0033]
Further, in the embodiment described above, the outer skin material F is formed into a bowl shape by the pushing member 30, but it is also possible to form a bowl shape by providing suction means on the support member instead of the pushing member 30. 30 to 33 show the food molding process. As shown in FIG. 30, the stay 52 of the holding means 5 is fixed to the cylinder 54, and the holding means 5 moves up and down as the cylinder 54 moves forward and backward. The support member 100 is constituted by a tubular member 102 provided with a plurality of ventilation holes 101 at the tip, and the tubular member 102 is connected to an intake / exhaust device (not shown). The support member 100 sucks and holds the outer skin material F by sucking air from the vent hole 101 and releases the outer skin material F sucked and held by exhausting it from the vent hole 101. In FIG. 30, the swing sealing means 1 is set to the retracted position, the shutter 2 is set to the closed state, and the outer skin material F having the inner material G disposed on the upper surface of the shutter 2 is supplied. In FIG. 31, after the shutter 2 is opened, the holding means 5 is lowered to press the peripheral edge portion of the outer skin material F against the upper surface of the shutter 2. The support member 100 moves upward and comes into contact with the lower surface of the outer skin material F, and sucks and holds the outer skin material F by sucking air from the air holes 101. In FIG. 32, the outer skin material F is formed in a bowl shape by the support member 100 descending in a state where the outer skin material F is adsorbed and held. Thereafter, as in the above-described embodiment, the holding means 5 rises and retreats, the swing sealing member 10 of the swing sealing means 1 starts to operate, and the tip end portion of the outer peripheral material F is the peripheral portion. Gather together. Then, in a state where the rocking sealing means 1 gathers the peripheral edge portions of the outer skin material F, the shutter 2 starts to operate, and further, the sealing operation is performed while gathering the peripheral edge portions of the outer skin material F.
[0034]
In the above-described example, the outer skin material F is held on the receiving member 2 by the presser member 50. However, if the outer skin material F does not deviate from the receiving member 70 when forming the hook shape, the holding material 50 is held. There is no need to provide means.
[0035]
Further, the number of sealing members of each sealing means is not particularly limited, and may be set as necessary. Furthermore, by arranging a plurality of such sealing means in parallel and driving them at the same time, the production efficiency is greatly improved, and the structure of the apparatus can be simplified by using a common drive shaft, and further downsizing can be achieved.
[0036]
Further, in the above-described example, the swing sealing means 1, the slide sealing means 8 and the sandwich sealing means 9 disposed above are performed up to the sealing operation. It is also possible to perform the process up to gathering and then seal with the shutter 2 and the slide sealing means 8 arranged below.
[0037]
【The invention's effect】
As described above, in the food molding apparatus according to the present invention, the outer shell material is disposed in the receiving means, and the sealing means is formed in a state where the central portion of the outer skin material is curved downward from the opening of the receiving means. Therefore, the inner material can be reliably wrapped and sealed with the outer skin material. That is, the peripheral portion of the outer skin material is arranged on the receiving means, so that the peripheral edge portion of the outer skin material is raised, so that reliable wrapping is possible. Further, even if the arrangement of the outer covering material at the receiving means is slightly deviated, if the outer covering material does not come out of the opening of the receiving means, the peripheral edge of the outer covering material is arranged in the sealing operation area of the sealing means, so that sealing by the sealing means is performed. There is no effect on the wearing operation. And since the support means supports the outer skin material, a stable sealing operation can be performed.
[0038]
By making the receiving means a receiving member having an opening, the outer skin material can be arranged in a stable state. In addition, since the receiving means includes a shutter that opens and closes a plurality of shutter pieces to form an opening, the size of the opening can be set as appropriate and can also serve as a sealing means. Furthermore, by providing the receiving means with positioning means for adjusting the position of the outer skin material, the position of the outer skin material can be surely arranged at an appropriate position, and the sealing operation by the shutter can be performed more reliably.
[0039]
In addition, when the outer shell material is formed in a hook shape at the opening of the receiving member, the hook material is formed by its own weight only by supplying the inner material onto the outer shell material. It can also be done. If the inner material is supplied at the same time as pressing, the production efficiency can be further improved. Further, if the outer skin material is sucked from the opening of the receiving member by suction means to form a hook shape, the outer skin material can be stably formed into a hook shape without pressing the outer skin material, and damage to the outer skin material Can be reduced. Then, by holding the edge portion of the outer skin material on the receiving member, it is possible to more reliably perform the hook-like formation and sealing operation of the outer skin material.
[0040]
In addition, the sealing means collects the sealing surfaces of a plurality of sealing members and performs a sealing operation so that the sealing material can be sealed while suppressing damage to the outer skin material, and is sealed to the front end of the sealing member. By forming the surface and advancing the sealing member to perform the sealing operation, an appropriate pressure-bonding force can be applied to the outer skin material. Then, when the supporting means moves downward during the sealing operation, a downward pulling force is applied together with the pressing force of the sealing member, so that the outer skin material can be more reliably sealed.
