【０００２】
【従来の技術】
本発明に係る先行例として、例えば特許第２９１７００３号公報がある。この先行例においては、ホッパーから降下する食品生地の通路の左右両側に配置した挟圧手段としての複数の挟圧ローラにより食品生地を挟圧することによって所定厚さのシート状生地に形成して連続的に供給しているものである。
【０００３】
【発明が解決しようとする課題】
前記先行例においては、ホッパーから降下する食品生地を効果的に挟圧し、シート状生地として連続的に供給する上において有効である。しかし、食品生地を挟圧してシート状生地とするとき、食品生地の通路の左右に列状に配置した挟圧ローラ群の少なくとも一方が他方の挟圧ローラに対して、上部側を中心として接近離反するように揺動を繰り返すものである。この挟圧ローラの接近離反の揺動動作時に、左右の挟圧ローラ列の下部が大きく開いたりするので、食品生地の性状によってはシート状生地の厚さに影響することがあり、シート状生地の厚さ精度のより正確さを求められることがある。

【０００９】
請求項６に係る発明は、生地受入れ部から降下する食品生地の通路の左右両側に、前記食品生地をシート状生地に形成すべく前記食品生地を挟圧自在の挟圧手段を配置した食品生地の連続供給装置において、一方の挟圧手段は大径の挟圧ローラで、他方の挟圧手段は複数の挟圧ローラを列状に備えた構成であって、上記一方の挟圧ローラと他方の複数の挟圧ローラ間の間隔を拡縮自在に設け、かつ前記一方の挟圧手段の下部側と他方の挟圧手段の下部側との間隔を常にほぼ一定に保持した構成であり、他方の複数の挟圧ローラは、大径の前記挟圧ローラに対して近接離反する方向へ個別に移動自在であることを特徴とするものである。
【００１０】
請求項７に係る発明は、生地受入れ部から降下する食品生地の通路の左右両側に、前記食品生地をシート状生地に形成すべく前記食品生地を挟圧自在の挟圧手段を配置した食品生地の連続供給装置において、左右の挟圧手段はそれぞれ径の異なる複数の挟圧ローラを列状に備えた構成であって左右の挟圧ローラ間の間隔を拡縮自在に設け、かつ左右の最下部の挟圧ローラの間隔を常にほぼ一定に保持した構成であり、左右の対をなす挟圧ローラは同一径であることを特徴とするものである。
【００１１】
【発明の実施の形態】
図１を参照するに、本発明の第１の実施の形態に係る食品生地の連続供給装置１は、例えばパン生地等の食品生地３の大きな団塊を受け入れるための生地受入れ部の１例としてのホッパー５を備えており、このホッパー５の下側の出口から降下する食品生地３の通路の左右両側には、前記食品生地３を所定厚さのシート状（帯状も同義）生地３Ａに形成すべく挟圧自在の複数の挟圧手段としての挟圧ローラ７Ｌ，７Ｒが回転自在に設けられている。
【００１２】
前記左右の挟圧ローラ７Ｌ，７Ｒは、ホッパー５内の食品生地３を下方向へ送るべくモータ（図示省略）によって互いに反対方向へ回転駆動されるものであって、両挟圧ローラ７Ｌ，７Ｒの軸間距離、すなわち両挟圧ローラ７Ｌ，７Ｒの間隔は、本実施の形態においては食品生地３の降下が生じ易いように比較的広く常にほぼ一定に保持されている。そして、左右の挟圧ローラ７Ｌ，７Ｒはホッパー５に対して相対的に上下動するように設けられている。
【００１３】
前記左右の挟圧ローラ７Ｌ，７Ｒの上下動は、図１（Ａ）に示すように同期して上下動する構成でも、また図１（Ｂ）に示すように、左右の挟圧ローラ７Ｌ，７Ｒが交互に上下動する構成でも良いものである。なお、左右の挟圧ローラ７Ｌ，７Ｒの間隔を常にほぼ一定に保持した状態において同期して上下動する構成や交互に上下動する構成は、例えばカム機構やリンク機構など種々の構成を採用することができるので、左右の挟圧ローラ７Ｌ，７Ｒを上下動する構成についての詳細な説明は省略する。
【００１４】
以上のごとき構成において、生地受入れ部の１例としてのホッパー５内に食品生地３の適宜形状の団塊３を投入又は搬入し、かつ左右の挟圧ローラ７Ｌ，７Ｒを、食品生地３を下方向へ送るべく互いに反対方向に回転し、さらに左右の挟圧ローラ７Ｌ，７Ｒを上下動すると、左右の挟圧ローラ７Ｌ，７Ｒ間に食品生地３が降下し、左右の挟圧ローラ７Ｌ，７Ｒにより挟圧されてシート状の生地３Ａに形成される。
【００１５】
上述のごとく左右の挟圧ローラ７Ｌ，７Ｒによって食品生地３をシート状生地３Ａに形成するとき、左右の挟圧ローラ７Ｌ，７Ｒが上下動することにより食品生地３に対する挟圧作用域が長くなると共に左右の挟圧ローラ７Ｌ，７Ｒの間隔をほぼ一定に保持してのならし作用効果があり、シート状生地３Ａの厚さ精度が向上するものである。さらに、左右の挟圧ローラ７Ｌ，７Ｒが下降する際には回転と相俟ってシート状生地３Ａに下方向への送り作用を付与することとなり、送り作用の向上を図ることができるものである。
【００１６】
また、図１（Ｂ）に示すように、左右の挟圧ローラ７Ｌ，７Ｒが交互に上下動する構成の場合には、ホッパー５内の食品生地３がシート状生地３Ａに形成される部分において食品生地３にうねり，くねり等を生じ、食品生地３に対して揉み上げ作用を付与する態様となり、食品生地３におけるグルテンの組織を強化できるものである。
【００１７】
さらに、左右の挟圧ローラ７Ｌ，７Ｒを上下動する際、上昇時と下降時の速度に応じて挟圧ローラ７Ｌ，７Ｒの回転速度が異なるように制御することにより、食品生地３の下方向への送り作用（排出作用）を制御でき、例えば下方向への食品生地３の送り速度をほぼ一定に制御することができる。また、場合によっては下流側の都合に合わせて送り速度を適宜に制御することができる。
【００１８】
図２は本発明の第２の実施の形態を示すもので、本実施の形態においては、複数の挟圧手段として左右両側にそれぞれ複数段に配置した複数の挟圧ローラ９Ａ，９Ｂ，９Ｃ；１１Ａ，１１Ｂ，１１Ｃを列状に備えた構成であって、上部側の左右の挟圧ローラ９Ａ，１１Ａの間隔よりも下部側の左右の挟圧ローラ９Ｂ，９Ｃ，１１Ｂ，１１Ｃの間隔の方がより狭くなるように、左右の挟圧ローラ列１３Ｌ，１３ＲはＶ字形状に配置してある。そして、最下部の左右のローラ９Ｃ，１１Ｃの間隔は、食品生地３を所定厚さのシート状生地３Ａに形成するように常にほぼ一定に保持されている。
【００１９】
前記左右の挟圧ローラ列１３Ｌ，１３Ｒにおける各挟圧ローラ９Ａ〜９Ｃ：１１Ａ〜１１Ｃは、回転速度は各々任意に調節可能であり、実施の形態においては、下側の挟圧ローラほど周速が大きくなるように回転され、食品生地３の挟圧と下方向への送り作用は円滑に行われるものである。
【００２０】
なお、図２（Ａ）の構成は、左右の挟圧ローラ列１３Ｌ，１３Ｒが同期して斜め方向に上下動する場合を例示し、図２（Ｂ）の構成は、左右の挟圧ローラ列１３Ｌ，１３Ｒを交互に斜め方向に上下動する場合を例示してある。
【００２１】
上記構成においては、左右の挟圧ローラ列１３Ｌ，１３ＲがＶ字形状の配置であることによりホッパー５から左右の挟圧ローラ列１３Ｌ，１３Ｒ内への食品生地３の降下がより容易であり、かつ挟圧作用域が前述の実施の形態よりもさらに長くなるものであって、食品生地３を揉み上げる作用がさらに向上するものである。そして、最下部の左右の挟圧ローラ９Ｃ，１１Ｃの間隔が常にほぼ一定に保持されることにより、シート状生地３Ａの厚さの均一性がより向上するものである。
【００２２】
ところで、左右の挟圧ローラ９Ａ〜９Ｃ：１１Ａ〜１１Ｃを上下動する際、上昇時と下降時の速度に応じて挟圧ローラ９Ａ〜９Ｃ：１１Ａ〜１１Ｃの回転速度が異なるように制御することにより、食品生地３の下方向への送り作用を制御でき、前述の実施の形態と同様の効果を奏し得るものである。
【００２３】
図３は本発明に係る第３の実施の形態を示すものである。この実施の形態においては、ホッパー５から降下する食品生地３の通路の左右両側に、前記食品生地３を挟圧するための挟圧手段としての複数の左右の挟圧ローラ１５Ａ〜１５Ｄ：１７Ａ〜１７Ｄを列状に備えた左右の挟圧ローラ列１９Ｌ，１９ＲをＶ字形状に配置し、かつ左右の挟圧ローラ列１９Ｌ，１９Ｒの下部付近を中心として、上部側が互いに接近離反する左右方向へ揺動可能に設けた構成である。この実施の形態においても、各挟圧ローラ１５Ａ〜１５Ｄ：１７Ａ〜１７Ｄの回転は前記第２の実施の形態の場合と同様である。
【００２４】
図３（Ａ）に示す構成は、左右の挟圧ローラ列１９Ｌ，１９Ｒにおいて間隔を一定に保持した最下部の挟圧ローラ１５Ｄ，１７Ｄを中心として左右の挟圧ローラ列１９Ｌ，１９Ｒの上部側を左右に揺動する構成としたもので、図３（Ｂ）に示す構成は、変形例として下から２段目の挟圧ローラ１５Ｃ，１７Ｃの間隔を一定に保持し、この挟圧ローラ１５Ｃ，１７Ｃを中心として左右の挟圧ローラ列１９Ｌ，１９Ｒを左右方向へ揺動自在に設けた構成である。
【００２５】
上記構成においては、左右の挟圧ローラ列１９Ｌ，１９Ｒの上部側が互いに近接離反するように左右方向に揺動することにより、ホッパー５から降下する食品生地３を挟圧し、所定厚さのシート状生地３Ａに形成することができる。
【００２６】
この際、左右の挟圧ローラ列１９Ｌ，１９Ｒの揺動中心は左右の挟圧ローラ列１９Ｌ，１９Ｒの下部側であって、ホッパー５から降下した食品生地３は既に薄く挟圧されており、かつ揺動中心又は揺動中心付近の左右の挟圧ローラの左右方向への拡幅は小さく常にほぼ一定であるから、挟圧されて移送されるシート状生地３Ａの厚さは常にほぼ一定厚さになるものであって、従来に比較してシート状生地３Ａの厚さが均一となるものである。
【００２７】
なお、左右の挟圧ローラ列１９Ｌ，１９Ｒの揺動中心は、挟圧ローラの軸心に限ることなく、例えば最下部の挟圧ローラ１５Ｄ，１７Ｄに近接した位置であれば良いものである。
【００２８】
図４は本発明の第４の実施形態を示すもので、この実施の形態においては、ホッパー５から降下する食品生地３の通路の一側に、一方の挟圧手段として大径の挟圧ローラ２１を、食品生地３を下方向へ送るべく回転自在に配置し、前記食品生地３の通路の他側に、他方の挟圧手段として複数の挟圧ローラ２３Ａ，２３Ｂ，２３Ｃを回転自在かつ前記大径の挟圧ローラ２１に対して相対的に近接離反する方向へ移動自在に備えた構成である。そして、前記大径の挟圧ローラ２１と前記挟圧ローラ２３Ｃの下方位置に、挟圧手段として間隔を常にほぼ一定に保持した左右一対の挟圧ローラ２５Ｌ，２５Ｒを配置した構成である。
【００２９】
上記構成において、各挟圧ローラを、食品生地３を下方向へ移送するように回転し、かつ複数の各挟圧ローラ２３Ａ，２３Ｂ，２３Ｃをそれぞれ個別に矢印Ｐ，Ｑ，Ｒ方向へ移動し、大径の挟圧ローラ２１との間隔を拡大，縮小することにより、ホッパー５から降下する食品生地３の挟圧を行うことができる。そして、最下部の一対の挟圧ローラ２５Ｌ，２５Ｒにより挟圧することにより、一定厚さのシート状生地３Ａに形成できるものである。
【００３０】
なお、上記構成においては、右側の複数の挟圧ローラ２３Ａ，２３Ｂ，２３Ｃ及び２５Ｒを挟圧ローラ列として１列に配置した構成として、最下部の挟圧ローラ２５Ｒを揺動中心として上記挟圧ローラ列の上部側を左右方向に揺動する構成としても良いものである。
【００３１】
図４（Ｂ）は、図４（Ａ）に示した構成の変形例を示すもので、挟圧ローラ２３Ａ，２３Ｂ，２３Ｃを楕円形状又は長円形状に構成した場合を示すものである。このように、挟圧ローラ２３Ａ，２３Ｂ，２３Ｃを長円形状に形成することにより、定位置で回転するのみでもって大径の挟圧ローラ２１との間隔を拡縮することができ、各挟圧ローラ２３Ａ，２３Ｂ，２３Ｃを、図４（Ａ）に示した矢印Ｐ，Ｑ，Ｒ方向に移動することを省略可能であるが、上記矢印方向に移動する構成であっても良いものである。
【００３２】
図５は本発明の第５の実施の形態を示すもので、ホッパー５から降下する食品生地３の通路の左右両側に配置した挟圧手段として、対をなす挟圧ローラが同一径であって径の異なる複数の偏心挟圧ローラ２７Ａ，２７Ｂ，２７Ｃ：２９Ａ，２９Ｂ，２９Ｃを、前記通路の下側ほど狭くなるように、左右の挟圧ローラ列３１Ｌ，３１Ｒとして備えた構成である。
【００３３】
上記構成においては、左右の挟圧ローラ列３１Ｌ，３１Ｒにおける偏心挟圧ローラ２７Ａ〜２７Ｃ，２９Ａ〜２９Ｃを、下側の挟圧ローラほど周速が大きくなるように回転することによってホッパー５から降下する食品生地３の挟圧を行い、最下部の偏心挟圧ローラ２７Ｃ，２９Ｃの間からほぼ一定厚のシート状生地３Ａとして送り出すものである。
【００３４】
ところで、上記構成においては、径の異なる各偏心挟圧ローラ２７Ａ〜２７Ｃ，２９Ａ〜２９Ｃを、例えば同期して回転すると、図５（Ａ）に示すように、下側ほど偏心挟圧ローラの径が小径となる構成においては、食品生地３は挟圧作用と圧縮作用とを受けるものであり、図５（Ｂ）に示すように、下側ほど偏心挟圧ローラの径が大径となる構成においては、食品生地３は挟圧作用と引き延ばし作用とを受けるものである。
【００３５】
したがって食品生地３の特性や製造しようとする製品の特性に対応して使い分けることにより、製品に対応した適正生地とすることができ、かつほぼ一定厚のシート状生地３Ａとして送り出すことができるものである。
【００３６】
ところで、上記構成においては、全ての挟圧ローラが偏心ローラである構成について説明したが、左右の挟圧ローラ列１３Ｌ，１３Ｒの１部分、例えば下部の挟圧ローラを偏心ローラでない通常の挟圧ローラの構成としたり、或は１部分の挟圧ローラのみを偏心挟圧ローラとした構成とすることも可能である。すなわち通常の挟圧ローラと偏心挟圧ローラとを適宜に組合せた構成とすることも可能である。
【００３７】
図６は本発明の第６の実施の形態を示すもので、この実施の形態は、図４に示した第４の実施形態の変更形態を示すものである。すなわち、この実施の形態は、第４の実施の形態に例示した大径の挟圧ローラ２１に代えて、軸３３を中心として回転自在の回転部材３５の同一円周上に複数の延展ローラ３７を回転自在に備えた構成であるから、前記回転部材３５及び複数の延展ローラ３７が大径の挟圧ローラに相当することとなるものであり、その他の構成は前述した第４の実施の形態と同一構成である。よって、同一機能を奏する構成部分には同一符号を付することとして重複した説明は省略する。なお、上記構成においても前述同様の効果を奏し得るものである。
【００３８】
【発明の効果】
以上のごとき説明より理解されるように、本発明によれば、ホッパー等の生地受入れ部から降下される食品生地を、食品生地の通路の左右両側に配置した挟圧手段によってシート状生地に挟圧形成するとき、挟圧手段における終段付近の間隔を常にほぼ一定に保持して挟圧し送り出すものであるから、シート状食品生地の厚さを常にほぼ均一に挟圧することができ、挟圧されて連続的に送り出される食品生地の厚さ精度を向上することができるものであり、前述したごとき従来の問題を解消し得るものである。

[0020]
2A illustrates the case where the left and right pressing roller rows 13L and 13R move up and down in an oblique direction in synchronization, and the configuration in FIG. 2B shows the left and right pressing roller rows. The case where 13L and 13R are alternately moved up and down in an oblique direction is illustrated.
[0021]
In the above configuration, the food dough 3 can be more easily lowered from the hopper 5 into the left and right pressure roller rows 13L and 13R because the left and right pressure roller rows 13L and 13R are V-shaped. In addition, the pressure application area is longer than that in the above-described embodiment, and the action of squeezing the food dough 3 is further improved. And the uniformity of the thickness of the sheet-like cloth 3A is further improved by maintaining the distance between the left and right nipping rollers 9C, 11C at a substantially constant level.
[0022]
By the way, when the left and right nipping rollers 9A to 9C: 11A to 11C are moved up and down, the rotation speeds of the nipping rollers 9A to 9C: 11A to 11C are controlled to be different depending on the rising speed and the descending speed. Thus, the downward feeding action of the food dough 3 can be controlled, and the same effect as in the above-described embodiment can be obtained.
[0023]
FIG. 3 shows a third embodiment according to the present invention. In this embodiment, a plurality of left and right clamping rollers 15A to 15D: 17A to 17D as clamping means for clamping the food dough 3 on both left and right sides of the passage of the food dough 3 descending from the hopper 5 are used. The left and right nipping roller rows 19L and 19R are arranged in a V shape, and the upper side swings in the left-right direction with the upper side approaching and separating from each other around the lower part of the left and right nipping roller rows 19L and 19R. This is a configuration that can be moved. Also in this embodiment, the rotation of the nipping rollers 15A to 15D: 17A to 17D is the same as that of the second embodiment.
[0024]
The configuration shown in FIG. 3A is the upper side of the left and right pressure roller rows 19L and 19R with the lowermost pressure roller rows 15D and 17D held at a constant interval in the left and right pressure roller rows 19L and 19R. The configuration shown in FIG. 3B is a modified example in which the interval between the pressing rollers 15C and 17C in the second stage from the bottom is kept constant, and the pressing roller 15C 17C, the left and right nipping roller rows 19L and 19R are provided so as to be swingable in the left-right direction.
[0025]
In the above configuration, the food dough 3 descending from the hopper 5 is clamped by swinging in the left-right direction so that the upper sides of the left and right pressing roller rows 19L, 19R come close to and away from each other. It can be formed on the fabric 3A.
[0026]
At this time, the center of oscillation of the left and right nipping roller rows 19L and 19R is the lower side of the left and right nipping roller rows 19L and 19R, and the food dough 3 lowered from the hopper 5 has already been thinly pinched, In addition, since the laterally widening width of the left and right pinching rollers near the rocking center or near the rocking center is small and almost constant, the thickness of the sheet-like material 3A transferred by being pinched is always almost constant. And the thickness of the sheet-like material 3A becomes uniform as compared with the conventional case.
[0027]
The center of swinging of the left and right nipping roller rows 19L and 19R is not limited to the axis of the nipping roller, but may be a position close to, for example, the lowermost nipping rollers 15D and 17D.
[0028]
FIG. 4 shows a fourth embodiment of the present invention. In this embodiment, a large-diameter pressing roller is provided as one pressing means on one side of the path of the food dough 3 descending from the hopper 5. 21 is rotatably arranged so as to feed the food dough 3 downward, and a plurality of nipping rollers 23A, 23B, and 23C are rotatably arranged on the other side of the passage of the food dough 3 as the other nipping means. This is a configuration that is movably provided in a direction that is relatively close to and away from the large-diameter pinching roller 21. A pair of left and right pressing rollers 25L and 25R is arranged below the large-diameter pressing roller 21 and the pressing roller 23C as the pressing means so that the distance is always kept substantially constant.
[0029]
In the above configuration, each pressing roller is rotated so as to transfer the food dough 3 downward, and each of the plurality of pressing rollers 23A, 23B, 23C is individually moved in the directions of arrows P, Q, R. The food dough 3 descending from the hopper 5 can be pinched by expanding and reducing the distance from the large-diameter pinching roller 21. And it can form in sheet-like cloth 3A of fixed thickness by pinching with a pair of lowermost pressure roller 25L and 25R.
[0030]
In the above-described configuration, the plurality of right-side nipping rollers 23A, 23B, 23C, and 25R are arranged in a single row as a nipping roller row. The upper side of the roller row may be configured to swing in the left-right direction.
[0031]
FIG. 4B shows a modification of the configuration shown in FIG. 4A, and shows a case where the nipping rollers 23A, 23B, and 23C are configured in an elliptical shape or an oval shape. Thus, by forming the pinching rollers 23A, 23B, and 23C into an oval shape, the distance from the large-diameter pinching roller 21 can be expanded and contracted only by rotating at a fixed position. Although it is possible to omit moving the rollers 23A, 23B, and 23C in the directions of arrows P, Q, and R shown in FIG. 4A, a configuration in which the rollers 23A, 23B, and 23C move in the directions of the arrows may be used.
[0032]
FIG. 5 shows a fifth embodiment of the present invention, in which paired nipping rollers have the same diameter as the nipping means arranged on the left and right sides of the passage of the food dough 3 descending from the hopper 5. A plurality of eccentric pinching rollers 27A, 27B, 27C having different diameters are provided as left and right pinching roller rows 31L, 31R so as to become narrower toward the lower side of the passage.
[0033]
In the above-described configuration, the eccentric clamping rollers 27A to 27C and 29A to 29C in the left and right clamping roller rows 31L and 31R are lowered from the hopper 5 by rotating so that the circumferential speed of the lower clamping roller increases. The food dough 3 is clamped and fed out as a sheet-shaped dough 3A having a substantially constant thickness from between the lowermost eccentric pressing rollers 27C and 29C.
[0034]
By the way, in the above configuration, when the eccentric clamping rollers 27A to 27C and 29A to 29C having different diameters are rotated in synchronization with each other, for example, as shown in FIG. In the configuration in which the diameter is small, the food dough 3 is subjected to a pinching action and a compression action, and as shown in FIG. 5 (B), the diameter of the eccentric pinching roller becomes larger toward the lower side. The food dough 3 is subjected to a pinching action and a stretching action.
[0035]
Therefore, by using properly according to the characteristics of the food dough 3 and the characteristics of the product to be manufactured, it is possible to obtain an appropriate dough corresponding to the product and to send it out as a sheet-shaped dough 3A having a substantially constant thickness. is there.
[0036]
By the way, in the above configuration, the configuration in which all the pressure rollers are eccentric rollers has been described. However, the normal pressure between the left and right pressure roller rows 13L and 13R, for example, the lower pressure roller is not an eccentric roller. It is also possible to adopt a configuration of a roller, or a configuration in which only one portion of the pressure roller is an eccentric pressure roller. That is, it is possible to adopt a configuration in which a normal nipping roller and an eccentric nipping roller are appropriately combined.
[0037]
FIG. 6 shows a sixth embodiment of the present invention, and this embodiment shows a modification of the fourth embodiment shown in FIG. That is, in this embodiment, instead of the large-diameter pinching roller 21 illustrated in the fourth embodiment, a plurality of extending rollers 37 are arranged on the same circumference of a rotating member 35 that is rotatable around a shaft 33. Since the rotation member 35 and the plurality of extending rollers 37 correspond to a large-diameter pinching roller, the other configurations are the same as those in the fourth embodiment described above. It is the same composition as. Therefore, the same reference numerals are assigned to components having the same function, and redundant description is omitted. The above-described configuration can also achieve the same effect as described above.
[0038]
【The invention's effect】
As can be understood from the above description, according to the present invention, the food dough lowered from the dough receiving portion such as a hopper is sandwiched between the sheet-like dough by the clamping means disposed on the left and right sides of the food dough passage. When the pressure is formed, the gap near the final stage in the clamping means is always held almost constant and fed out, so that the thickness of the sheet-like food dough can always be clamped almost uniformly. Thus, the thickness accuracy of the food dough that is continuously fed out can be improved, and the conventional problems as described above can be solved.
