Description
本発明は、コンベアにて搬送されるシート状ないしブロック状の豆腐生地を搬送方向に沿って所定サイズに切断し間隔を開ける豆腐生地製造装置の切断装置に関する。 The present invention relates to a cutting device of a tofu dough manufacturing apparatus for cutting a sheet-like or block-like tofu dough transported by a conveyor into a predetermined size along the transport direction and spacing.
従来は、連続成型機にて連続的に凝固成型されたシート状の豆腐生地は、連続成型機の下側コンベアによって水中ないしは陸上に搬送されながら、固定のロール切断刃によって搬送方向（列方向）に沿って製品１個分（１丁分）の列幅で縦切りされて、次に搬送方向と直交する方向（行方向）で製品１個分（１丁分）の行幅で横切りされる（特許文献１、３、８、９）。また同様に型箱で成型されたブロック状の豆腐生地が水中ないしは陸上で移送されながら、切断機構にて搬送方向と直交する方向に切断（横切り）され、その横切りでは製品１個分（１丁分）の行幅で１行分の小さいブロック状の豆腐を切り出す。次に、小さいブロック状の豆腐が水中で移送されながら、列方向の切断分配機構にて搬送方向に沿って所定間隔で切断され間隔を開けられて整列された状態となり、パック詰め機構（自動パック詰め装置）にてパック詰めされる（特許文献２、４〜７）。豆腐を油揚げ等の揚げ物とする場合には、切断分配機構の下流にフライヤーが配される。豆腐を凍り豆腐や冷凍豆腐とする場合には、切断分配機構の下流にフリーザーが配される。本明細書では、木綿豆腐や絹ごし豆腐、ソフト木綿豆腐、ソフト豆腐、油揚げ生地、厚揚げ生地、生揚げ生地、凍り豆腐生地、これらの冷凍豆腐生地または凍結乾燥豆腐生地（FD；フリーズドライ）の食品を豆腐生地と称する。なお、豆乳や豆腐生地は本機構の前後工程は特に限定せず、例えば殺菌処理された豆乳や豆腐生地でもよい。 Conventionally, a sheet-like tofu dough continuously coagulated and formed by a continuous forming machine is conveyed by the lower roller of the continuous forming machine underwater or on land while the conveying direction (row direction) by a fixed roll cutting blade Is cut longitudinally with a column width of one product (one branch) and then traversed by a row width of one product (one branch) in the direction (row direction) orthogonal to the transport direction (Patent documents 1, 3, 8, 9). Similarly, while a block-like tofu dough molded in a mold box is transported in water or on land, it is cut (crossed) in a direction orthogonal to the transport direction by the cutting mechanism, and one cross (one cut) Cut out a small block of tofu with a line width of 1). Next, while small blocks of tofu are transferred in water, they are cut at predetermined intervals along the transport direction by the cutting and dispensing mechanism in the row direction, and are spaced apart and aligned, and the packing mechanism (automatic packing The packing apparatus) packs (patent documents 2, 4-7). When tofu is used as fried food such as fried food, a fryer is disposed downstream of the cutting and dispensing mechanism. When tofu is frozen tofu or frozen tofu, a freezer is disposed downstream of the cutting and dispensing mechanism. In the present specification, foods of cotton tofu, silk tofu, soft tofu, soft tofu, deep-fried dough, thick-fried dough, fresh-fried dough, frozen tofu dough, foods of these frozen tofu dough or freeze-dried tofu dough (FD; freeze-dried) It is called tofu dough. In addition, soymilk and tofu dough are not particularly limited before and after the process of the present mechanism, and may be, for example, sterilized soymilk or tofu dough.
従来、上記ベルト状の豆腐生地（ブロック状の豆腐生地）は、コンベアにて搬送されながら、水の無い状態（陸上）で切断されるか、水中で切断される。水の無い状態で豆腐を切断する切断分配機構としては、例えば特許文献１から３が文献公知となっており、水中で豆腐を切断する切断分配機構としては、例えば特許文献４から７が文献公知となっている。 Conventionally, the belt-like tofu dough (block-like tofu dough) is cut in a water-free state (land) or cut in water while being transported by a conveyor. For example, Patent Documents 1 to 3 are publicly known documents as a cutting and distributing mechanism for cutting tofu in the absence of water, and for example, Patent Documents 4 to 7 are known for example as a cutting and distributing mechanism for cutting tofu in water. It has become.
ところで、豆腐生地の量産が可能な自動連続製造ラインにおいては、製造原価低減のため高速化が求められている。特許文献３のように時間あたり３，０００〜４，０００丁の処理能力に高める形態が示されているが、その数倍の処理能力が要求され、機械の動きも更なる高速化が求められている。また、近年のパック詰め作業は、高速化処理と共に、多様なバリエーションが求められており（例えば、多数列同時パック詰め）、又、油揚げ工程、焼き工程、冷凍工程等に移行する際にも、多様な大きさや形状のバリエーションが求められ、これに合わせた搬送も要求されている。 By the way, in an automatic continuous manufacturing line capable of mass-producing tofu dough, speeding up is required to reduce the manufacturing cost. Although the form of increasing the processing capacity to 3,000 to 4,000 per hour as shown in Patent Document 3 is shown, several times the processing capacity is required, and further speeding up of machine motion is also required. ing. Also, in recent years, packing operations are required to have various variations along with speed-up processing (for example, packing in multiple rows simultaneously), and also when shifting to a frying process, a baking process, a freezing process, etc. A variety of variations in size and shape are required, and transport in accordance with this is also required.
他方、従来の切断方法では、連続成型機にて連続的に凝固成型されたシート状の豆腐生地を第１切断工程で先ず例えばパック詰めする大きさ（豆腐生地最小単位）の１丁分の列幅で列方向に切断して、水槽中に入れて、このパック詰め列方向（１丁分の幅）の豆腐生地を搬送コンベアで搬送させながら第２切断工程で行方向に１丁ごとに切断して水中でパック詰めする（特許文献８）。 On the other hand, in the conventional cutting method, a sheet of tofu dough continuously coagulated and formed by a continuous forming machine is firstly packed in a first cutting step, for example, in one row of a size (minimum unit of tofu dough) to be packed. It is cut in the column direction by width, put in the water tank, and this tofu dough in the packed row direction (width of 1 section) is transported by the conveyer and cut by 1 in the row direction in the second cutting step And packed in water (Patent Document 8).
しかしながら、連続成型機にて連続的に凝固成型されたシート状の豆腐生地を切断工程でパック詰めする大きさ（１丁分の行幅）で１行単位で切断する形態では、豆腐生地を傷めないように切ってゆっくり送り出す動作が必要で切断工程にかかる時間の制約から、連続ラインの処理能力は概ね時間あたり５，０００丁が限界であった。無理に切断工程の各動作速度を速めると、豆腐生地を傷めたり、搬送ベルト上をスリップして定位置を外れて切断寸法精度が低下し、機械的な耐久性も低下する事態になるなどの問題を有していた。このため、その後の工程でパック詰め等すると、欠けや重量不足等の不良品として扱われることが多くなる。特に、柔らかい豆腐生地では変形やロスを生じ難くしつつ高精度で切断することは難しかった。なお、油揚げ工程においても、生地が傷んだり、切断寸法がバラツクと、油揚が変形する等のロスを増やす結果になった。 However, the tofu dough is damaged when it is cut in units of one row with a size (one line width) in which the sheet-like tofu dough continuously solidified and formed by the continuous forming machine is packed in the cutting step. Due to the restriction of time required for cutting process so as not to cut off and feed slowly, the processing capacity of the continuous line was almost limited to 5,000 per hour. If each operation speed in the cutting process is forcedly increased, the tofu dough may be damaged, or the conveyor belt may slip, deviating from the fixed position, cutting dimensional accuracy may decrease, and mechanical durability may also decrease. I had a problem. For this reason, if packing etc. are carried out by subsequent processes, it will be treated as inferior goods, such as a chipping and lack of weight, in many cases. In particular, with soft tofu dough, it was difficult to cut with high precision while making deformation and loss difficult to occur. Also in the frying process, the dough is damaged, and the cutting dimension is increased, resulting in an increase in losses such as deformation of the frying.
そこで本発明の目的は、柔らかい豆腐生地でも傷めにくく変形やロスを生じ難くしつつ高精度で切断するとともに、パック詰めや油揚げ工程等への搬送を多様でかつ効率的にして処理能力を時間あたり５，０００〜２０，０００丁と高めた連続製造ラインを提供することを目標として、律速工程である切断工程を改善した高い処理能力を有する豆腐生地の切断装置を提供することを目的とする。 Therefore, the object of the present invention is to cut with high precision while making soft tofu dough resistant to damage and less likely to cause deformation or loss, and to carry out processing to packing process and frying process variously and efficiently for processing capacity per hour An object of the present invention is to provide an apparatus for cutting a tofu dough having a high throughput and an improved continuous cutting process, which is a rate-limiting process, with the goal of providing a continuous production line of 5,000 to 20,000.
（１）本発明は、豆腐生地搬送装置により連続的に搬送されて成型されるシート状豆腐生地において、搬送コンベヤの進行方向を列方向、搬送コンベヤの進行方向と直角に交わる方向を行方向として、前記シート状豆腐生地から少なくとも１つ以上の行方向の横切り切断刃を備えた少なくとも１つ以上の横切り切断ユニットを備えて、前記横切り切断ユニットを介して得られた細帯状豆腐生地の少なくとも２行以上の複数行分の帯状豆腐生地を列方向に切断する縦切り切断刃を行方向に少なくとも１枚以上備え列方向に沿って切断するように配設した縦切り切断ユニットを備え、
前記縦切り切断ユニットは、複数行分の前記帯状豆腐生地を列方向及び／又は行方向の位置決め手段によって位置決めさせた状態にして前記縦切り切断刃で切断するか、又は、複数行分の前記帯状豆腐生地を列方向及び／又は行方向の位置決め手段によって位置決めさせた状態にした後に該帯状豆腐生地から該位置決め手段が離れた後に前記縦切り切断刃で切断することを特徴とする。
ここで、連続的に搬送されて成型されるシート状豆腐生地とは、連続成型機で連続して無端状に成型されて、最小単位の豆腐生地が行方向にＮ個分及び／又は高さ方向にＬ個分に相当し（Ｎ≧２、Ｌ≧１）、かつ列方向に多数個分（Ｍ≒∞）に相当する無端状豆腐生地であり、又は連続成型機で型枠を備えた形態で行方向にＮ個分及び／又は高さ方向にＬ個分に相当し（Ｎ≧２、Ｌ≧１）、かつ列方向にＭ個分（Ｍ≧２）に相当するブロック状豆腐生地である。連続成型機の下布や下側キャタピラー等の搬送ベルトの駆動は一般に連続駆動であるが、後工程の切断装置等と同期連動する断続駆動であってもよい。太帯状豆腐生地とは、豆腐生地最小単位の少なくとも２個分の辺に相当する長さを列方向の短辺に有し、豆腐生地最小単位の少なくとも２個分の辺に相当する長さを行方向の長辺に有する略直方体であって豆腐生地最小単位の複数分が行列状に配列した豆腐生地である。細帯状豆腐生地とは、豆腐生地最小単位の少なくとも１個分の辺に相当する長さを列方向の短辺に有し豆腐生地最小単位の少なくとも２個分の辺に相当する長さを行方向の長辺に有する略直方体であって豆腐生地最小単位の複数分が１行状に配列した豆腐生地である。いずれの帯状豆腐生地も両端の生地耳を除去する場合は、行方向の長辺の長さは取り除く両端の生地耳の長さを加えた長さになる。 本発明の豆腐生地は油揚生地、薄揚げ・厚揚げの生地、生揚げ・絹生揚げの生地、焼き豆腐生地、ソフト木綿豆腐、木綿豆腐、ソフト豆腐、絹ごし豆腐、これらの冷凍豆腐生地、凍結乾燥豆腐生地などを含む。 従来、豆腐生地の連続製造装置では、連続的に成型・搬送されるベルト状豆腐を各製品サイズに切断して間隔を広げるように整列する切断・整列工程は全体のライン能力を決定する律速工程の一つである。従来は第１切断で１列ごとに切断し、第２切断で１行ごとに切断する方式である（特許文献８）。これに対して、本発明における細帯状豆腐生地は、第１の切断工程で１枚の横切り切断刃によって１回の動作で切り出す細帯状豆腐生地１行分、又は第１の切断工程で複数の横切り切断刃によって１回の動作で切り出す細帯状豆腐生地の複数行分、又は第１の切断工程で１枚の横切り切断刃によって１回の動作で切り出して横倒しにした太帯状豆腐生地１行分を経て得られた細帯状豆腐生地複数行分、又は第１の切断工程で少なくとも２行以上の太帯状豆腐生地をまとめて１枚の横切り切断刃によって１回の動作で切り出して、第２の切断工程で１枚の横切り切断刃によって１行ごとに１回の動作で切断する２段階の切断工程で切り出す細帯状豆腐生地の複数行分などであって、行方向に細長い細帯状豆腐生地に切断される形態であれば切断手段や切断機構や切断回数などは特に限定しない。本発明ではこれら細帯状豆腐生地の少なくとも２行分をまとめて縦切り切断工程で１丁（１個）毎に切断する。ここで、１丁（１個）の豆腐生地とは包装製品の最小単位ないしは後工程に必要な最小サイズであり、冷凍工程やフライ工程等に応じたサイコロ形や賽の目形や短冊形等の小さなサイズまで含む。なお、縦切り切断工程で１回で切断する細帯状豆腐生地の行数は、前工程の横切り切断工程で１回に切り出す太帯状豆腐生地の相当行数ないしは細帯状豆腐生地の行数と同じでも、異なってもよい。
本発明によれば、縦切り切断工程において前工程（第１の切断工程ないしは第２の切断工程など）から搬送された複数行の細帯状豆腐生地を列方向に切断する縦切り切断刃を１つ以上備えた縦切り切断刃ユニットによって複数行及び複数列に配列する複数の豆腐生地最小単位に一斉に同時またはほぼ一斉ないしはほぼ同時に切断するので、１工程ないしは１動作（切断刃の上下１回の往復動作ないしは回動動作、列方向で下流〜上流間で一方向に動かす水平動作ないしは回転動作など）で多数の最小単位の豆腐生地（１個分）を同時ないしはほぼ同時に得ることができ、切断処理能力を大幅に高める効率的な切断が可能である。縦切り切断刃は行方向に少なくとも１枚以上で平行に並べた形態あって、細帯状豆腐生地の両端を耳として切断する場合は行方向の豆腐生地最小単位の数（Ｎ）に１つ多い数（Ｎ＋１）を備える。縦切り切断刃は中華包丁型切断刃、ナイフ型切断刃、円形切断刃（ロールカッター）等で昇降動作、回動動作、回転動作、水平動作、往復動作、一定方向の周回動作等を行う機構を備える。切断動作では搬送コンベアの駆動と合わせて列方向に切断するようにしてもよい。これら縦切り切断刃やその切断動作を適宜組み合わせて同時ないしほぼ同時に、複数行の細帯状豆腐生地を略一度に、略一斉に切断する。ここでほぼ同時とは、例えば下流側細帯状豆腐生地の下流側から切断刃が切り込み、上流側の細帯状豆腐生地の上流側へ切断刃が水平動作して１動作で短時間に順次に切断することを意味する。
ここで縦切り切断刃が中華包丁型切断刃の場合は切断後、搬送ベルトから少し離して行方向に横移動して、最小単位の豆腐生地の行方向の間隔を広げて整列させる動作も行ってもよい（図３）。また縦切り切断刃がナイフ型切断刃やロールカッターの場合は後述する千鳥式の豆腐生地分配整列方法であっても、２つ以上の搬送コンベアによる速度差分配整列方法であってもよい。また、第３の切断刃は、下降動作して押し切りする場合に限らず、引き切りする包丁を第３の縦切りに使っても良い（図３５）。引き切りするナイフ型やロール型切断刃の方が接触面が少なく洗浄しやすく衛生的である。
また従来と同じように、前記連続成型されるシート状豆腐の両端は角に丸みや不良な表面があり、両端の一部は耳として切断して取り除く場合では、豆腐自身の柔らかさやダレ具合（自重による行方向への広がり方）による拡張、冷却時の収縮も考慮した上で、前記太帯状豆腐生地ないしは前記細帯状豆腐生地の行方向の長さは豆腐生地最小単位の複数分の長さに追加して生地耳分だけ少し長めに設定される。 本発明によれば、連続的に成型されるシート状豆腐生地から１個分の行幅を有する細長い細帯状豆腐生地に縦切り切断工程でまとめて切断するので、機械的動作を可及的に速くでき、機械的動作時間に余裕を作ることができ、更に好ましくは後述の（２）のように積極的に位置決めして切断するので、陸上においても従来よりも高い切断精度で効率的で大量生産向きである。結果的に型崩れや味抜けが防止でき、柔らかい豆腐生地であっても、豆腐生地の歪みを防止して、精度よく綺麗に切断することができる。 特に本発明としては、豆腐生地搬送装置により連続的に搬送されて成型される複数分のシート状豆腐生地から第１の切断工程によって切り出された太帯状豆腐生地から、複数行の細帯状豆腐生地に切断する第２の切断工程を経て、縦切り切断刃ユニットによって、列方向に一斉に同時ないしはほぼ同時に切断して、複数行及び複数列に配列する複数個の豆腐生地最小単位に切断する縦切り切断工程を備える多段階切断工程を構成することが好ましく、従来よりも切断処理能力を大幅に向上させることができる。
(1) In the present invention, in the sheet-like tofu dough continuously conveyed and molded by the tofu dough conveying apparatus, the advancing direction of the conveying conveyor is a row direction, and the direction intersecting the advancing direction of the conveying conveyor is a row direction At least 2 of strip-shaped tofu dough obtained through the cross cutting unit, comprising at least one or more cross cutting units provided with at least one or more row-direction cross cutting blades from the sheet-like tofu dough; A longitudinal cutting unit provided with at least one longitudinal cutting blade in the row direction for cutting a plurality of rows or more of band-like tofu dough in the column direction and arranged to cut along the column direction,
The vertical cutting unit cuts a plurality of rows of the tofu dough in a state of being positioned by the positioning means in the column direction and / or the row direction and cuts with the vertical cutting blade, or the plurality of rows It is characterized in that the banded tofu dough is positioned by the positioning means in the row direction and / or the row direction and then cut by the vertical cutting blade after the positioning means is separated from the banded tofu dough.
Here, the sheet-like tofu dough continuously conveyed and formed is continuously formed into an endless shape by a continuous forming machine, and the minimum unit of tofu material is N pieces and / or the height in the row direction Endless tofu dough corresponding to L pieces in the direction (N 2 2, L 1 1) and in the row direction to a large number (M ∞)), or with molds in a continuous forming machine Block shape tofu dough corresponding to N pieces in the row direction and / or L pieces in the height direction (NN2, L ≧ 1) and M pieces in the column direction (M ≧ 2) It is. Driving of the transport belts such as the lower cloth and the lower caterpillar of the continuous forming machine is generally continuous driving, but may be intermittent driving synchronized with a cutting device or the like in a post process. The thick band tofu dough has a length corresponding to at least two sides of the minimum unit of tofu dough on the short side in the column direction, and a length corresponding to at least two sides of the minimum unit of tofu dough It is a substantially rectangular parallelepiped having long sides in the row direction, and a plurality of tofu dough minimum units are arrayed in a matrix. The fine banded tofu dough has a length corresponding to at least one side of the minimum unit of tofu dough in the short side in the column direction and a length corresponding to the side of at least two minutes of the minimum unit of tofu dough. It is a substantially rectangular solid having long sides in the direction, and a plurality of tofu dough minimum units are arrayed in one row. When removing the dough ears at both ends of the banded tofu dough, the length of the long side in the row direction is the length obtained by adding the lengths of the dough ears at both ends to be removed. The tofu dough of the present invention is a deep-fried dough, a deep-fried / deep-fried dough, a fresh-fried / silk-fried dough, a baked tofu dough, a soft cotton tofu, a cotton tofu, a soft tofu, a silk tofu, a frozen tofu dough of these, a freeze-dried tofu dough And so on. Conventionally, in a continuous production apparatus for tofu dough, a cutting and aligning step of cutting continuously shaped and transported belt-like tofu into product sizes and aligning so as to widen the interval is a rate-limiting step that determines the entire line capacity. one of. The conventional method is a method in which the first cutting is performed for each row, and the second cutting is performed for each row (Patent Document 8). On the other hand, the strip-shaped tofu dough according to the present invention is a strip of strip-shaped tofu dough cut out in one operation by a single cross-cutting blade in the first cutting step, or a plurality of strips in the first cutting step. A line of thin band-like tofu dough cut out in one operation with a cross cutting blade, or a thick line of tofu dough cut out in a single operation with a single cross cutting blade in a first cutting step A plurality of rows of strip-shaped tofu dough obtained through the above, or at least two rows of thick strip-shaped tofu dough in a first cutting step are cut out in one operation with a single transverse cutting blade, A plurality of rows of strip-shaped tofu dough cut out in a two-step cutting step in which one cross-cut cutting blade cuts one row at a time in a cutting step; Cutting if it is a form to be cut Not particularly limited, such as the stage and the cutting mechanism and the number of cuts. In the present invention, at least two rows of these thin band-like tofu doughs are cut together in a longitudinal cutting step. Here, one (1) piece of tofu dough is the smallest unit of the packaged product or the smallest size necessary for the post process, and it is small such as a dice shape or a box shape or a strip shape corresponding to a freezing process or a frying process. Including the size. The number of rows of strips of tofu dough cut at one time in the longitudinal cutting process is the same as the number of equivalent rows of thick tofu dough cut at one time in the cross-cutting process of the previous step or the number of rows of stripy tofu dough. But it may be different.
According to the present invention, in the longitudinal cutting step, the longitudinal cutting blade for cutting a plurality of rows of strip-shaped tofu dough conveyed from the previous step (the first cutting step to the second cutting step etc.) in the row direction 1 One step or one operation (one time up and down the cutting blade) because it cuts simultaneously or almost simultaneously or almost simultaneously to a plurality of tofu dough minimum units arranged in a plurality of rows and a plurality of rows by a vertical cutting blade unit equipped with two or more A plurality of minimum unit of tofu dough (one piece) can be obtained simultaneously or almost simultaneously by reciprocation operation or rotation operation, horizontal operation or rotation operation to move in one direction between downstream and upstream in the row direction, etc.) Efficient cutting is possible, which greatly increases the cutting capacity. The vertical cutting blade has a form in which at least one sheet is arranged in parallel in the row direction, and when cutting both ends of the strip-like tofu dough as an ear, the number (N) of tofu dough minimum units in the row direction is one more It has a number (N + 1). The vertical cutting blade is a mechanism that performs lifting and lowering operation, rotation operation, rotation operation, horizontal operation, reciprocation operation, circling operation in a fixed direction, etc. with Chinese knife type cutting blade, knife type cutting blade, circular cutting blade (roll cutter) etc. Equipped with In the cutting operation, cutting in the row direction may be performed together with the drive of the transport conveyor. At the same time or approximately simultaneously with the vertical cutting blades and their cutting operations, a plurality of rows of strip-shaped tofu dough are cut substantially simultaneously and substantially simultaneously. Here, “almost simultaneously” means that, for example, the cutting blade cuts from the downstream side of the downstream thin banded tofu dough, and the cutting blade moves horizontally to the upstream side of the thin banded tofu dough upstream, and cuts sequentially in a short time in one operation. It means to do.
In this case, if the vertical cutting blade is a Chinese knife-shaped cutting blade, move it a little further away from the conveyor belt and move it horizontally in the row direction to widen and align the rows of tofu dough in the minimum unit. It may be (FIG. 3). When the vertical cutting blade is a knife type cutting blade or a roll cutter, it may be a staggered type of tofu dough distribution alignment method described later, or a speed difference distribution alignment method by two or more conveyers. Further, the third cutting blade is not limited to the case of pressing down by lowering operation, and a knife to be pulled out may be used for the third vertical cutting (FIG. 35). A knife-type or roll-type cutting blade that pulls off has a small contact surface and is easy to clean and hygienic.
Also, as in the conventional case, both ends of the sheet-shaped tofu to be continuously molded have rounded or defective surfaces at the corners, and in the case where a part of the ends is cut and removed as an ear, the tofu itself's softness and dripping In consideration of expansion due to its own weight in the row direction) and shrinkage at the time of cooling, the length in the row direction of the thick zonate tofu dough or the zonate tofu dough is several minutes of the minimum unit of tofu dough In addition to the dough ear minutes are set slightly longer. According to the present invention, since the continuous molding sheet-like tofu dough is cut into a long strip-like tofu dough having a row width for one piece in the longitudinal cutting process, the mechanical operation is possible as much as possible Fast and efficient mechanical operation time, and more preferably positively positioned and cut as described in (2) below. It is suitable for production. As a result, it is possible to prevent the shape loss and taste loss, and even if it is a soft tofu dough, it is possible to prevent the distortion of the tofu dough and to cut it precisely and precisely. In particular, according to the present invention, a plurality of rows of strip-like tofu dough are cut from a large strip-like tofu dough cut out by a first cutting step from a plurality of sheet-like tofu dough continuously transported and molded by a tofu dough transport device. Through a second cutting step of cutting into a plurality of tofu dough minimum units which are simultaneously or substantially simultaneously cut in the row direction by the vertical cutting blade unit simultaneously and in multiple rows and multiple columns It is preferable to configure a multi-step cutting process including a cutting process, and the cutting capacity can be significantly improved as compared to the prior art.
（２）本発明としては、（１）の豆腐生地の切断方法であって、複数行の前記細帯状豆腐生地を各々列方向及び／又は行方向の位置決め手段によって位置決めさせた状態にして前記縦切り切断刃で切断するか、又は、複数行の前記細帯状豆腐生地を各々列方向及び／又は行方向の位置決め手段によって位置決めさせた状態にした後に該細帯状豆腐生地から該位置決め手段が離れた後に前記縦切り切断刃で切断する、縦切り切断工程を備えることを特徴とする。
本発明によれば、予め位置決め手段により位置決めして正確な切断を行うことができる。その位置決めは縦切り切断工程で切断直前に行うか、ないしは前工程の切断工程の直後、行間の間引きに用いた前工程の切断刃によって押し送る動作と兼ねてもよく、前工程の切断工程における位置決め手段によって位置決めされて細帯状豆腐生地から離れた後に搬送コンベアで位置が変わらないように縦切り切断工程に搬送される形態であってもよい。位置決め手段は位置決め部材の動作単独なしいは搬送コンベア動作との協働によって位置決めする形態であってもよい。本発明によれば、連続的に成型されるシート状豆腐生地から１個分の行幅を有する細長い細帯状豆腐生地に縦切り切断工程でまとめて切断するので、機械的動作を可及的に速くでき、機械的動作時間に余裕を作ることができ、更に好ましくは位置決めして切断するので、従来よりも高い切断精度で効率的で大量生産向きである。結果的に型崩れや味抜けが防止でき、陸上であっても、柔らかい豆腐生地であっても、豆腐生地の歪みを防止して、精度よく綺麗に切断することができる。また本発明によれば、縦切り切断工程で細帯状豆腐生地を停止させた状態から離れる瞬間の直前や直後以降に切断すると、最小単位の豆腐生地と切断刃や位置決め部材との密着性による最小単位の豆腐生地の位置ずれを軽減できるとともに、片側位置決めや両側位置決めを行なった後、離れても、豆腐生地の安定感を保って切断することができる。
ここで、停止させた状態した後に細帯状豆腐生地から離れた状態にしてとは、位置決め手段や位置決め手段を兼用する前工程の切断刃などが、細帯状豆腐生地を位置決めした停止状態から離れる瞬間や、その直前ないしはその直後ないしはそれ以降の状態であり、また搬送コンベア上において上流側で位置決めしてから下流側に移動して切断される形態でもよく、縦切り切断工程の直前ないしは手前の位置で一旦位置決めした状態にしておくことである。特に陸上での切断時においてダレが少ない硬い豆腐生地において好ましい形態である。柔らかい豆腐生地においても、無理に位置決め手段で挟んだり押されると、その際に細帯状豆腐生地を傷めたり、位置決め手段に接することによる細帯状豆腐生地の歪みがあるまま切断されて、歪んで不均等な形になり、Ｂ級品やロスになる場合もあるからである。そのため細帯状豆腐生地にかかる歪みを除いてから切断することで、不均等な形の製品を少なく、全体を平均化できる場合がある。また一旦位置決めして位置決め部材が細帯状豆腐生地から離れて、歪みなどを修正して、再び切断時に細帯状豆腐生地に接して位置決めしながら切断する形態であってもよく、また位置決め部材が何回か細帯状豆腐生地に接したり離れたりの繰り返し動作を行って歪みを平均的に修正してから切断する形態であってもよい。この場合、切断時は細帯状豆腐生地から離れていても、接していてもよい。
(2) The present invention is the cutting method of tofu dough according to (1), wherein the strip-like tofu dough in a plurality of rows is positioned by means of positioning means in the column direction and / or row direction. The positioning means is separated from the strip-like tofu dough after cutting with a cutting blade or after positioning the plurality of rows of the strip-like tofu dough in the row direction and / or the row direction positioning means It is characterized by including a vertical cutting step of cutting later by the vertical cutting blade.
According to the present invention, accurate cutting can be performed by positioning in advance by the positioning means. The positioning may be performed immediately before cutting in the vertical cutting process, or may be performed immediately after the cutting process in the previous process, or may be performed by the cutting blade of the previous process used for thinning between rows. After being separated by the positioning means and separated from the strip-like tofu dough, it may be conveyed to the longitudinal cutting process so that the position does not change on the conveying conveyor. The positioning means may be in the form of positioning by the movement of the positioning member alone or in cooperation with the conveyor operation. According to the present invention, since the continuous molding sheet-like tofu dough is cut into a long strip-like tofu dough having a row width for one piece in the longitudinal cutting process, the mechanical operation is possible as much as possible As it can be made faster, mechanical operation time can be spared, and positioning and cutting are more preferable, it is efficient and suitable for mass production with higher cutting accuracy than before. As a result, it is possible to prevent the shape loss and the taste loss, and it is possible to prevent the distortion of the tofu dough and to cut it precisely with good precision, even on land or in a soft tofu dough. Further, according to the present invention, when cutting is performed immediately before or after the moment when the strip-like tofu dough is stopped in the longitudinal cutting process, the minimum value is obtained due to the adhesion between the smallest unit of tofu dough and the cutting blade or positioning member. While being able to reduce the positional deviation of the tofu dough of a unit, after performing one-sided positioning or both-side positioning, even if it leaves, it can cut | disconnect, maintaining the sense of stability of tofu dough.
In this case, if it is separated from the strip-shaped tofu dough after being stopped, the positioning blade or the cutting blade in the previous step which also serves as the positioning unit is instantaneously removed from the stopped state in which the strip-shaped tofu dough is positioned. Alternatively, it may be positioned immediately upstream or immediately after or after it, positioned upstream on the transport conveyor, and then moved downstream for cutting, and may be positioned immediately before or before the longitudinal cutting process. It is to be in the state of positioning once. In particular, it is a preferable form in hard tofu dough with little dripping at the time of cutting on land. Even if soft tofu dough is forcibly pinched or pressed by the positioning means, it may damage the strip-shaped tofu dough at that time, or it may be cut with distortion of the strip-like tofu dough due to contact with the positioning means. It becomes an even form, and it may be a B grade product or loss. Therefore, it may be possible to reduce the amount of uneven products and average the whole by cutting after removing distortion applied to the minced tofu dough. Alternatively, the positioning member may be positioned once, separated from the strip-shaped tofu dough, corrected for distortion, etc., and may be cut while being positioned in contact with the strip-shaped tofu dough again at the time of cutting. The distortion may be corrected on the average after repeated operations of touching or separating to the thin band-like tofu dough, and then cutting may be performed. In this case, it may be separated from or in contact with the strip-like tofu dough at the time of cutting.

（６）本発明としては、豆腐生地の切断装置であって、豆腐生地搬送装置の進行方向を列方向、その進行方向と直角に交わる方向を行方向として、連続的に搬送されて成型されるシート状豆腐生地から少なくとも１つ以上の行方向の横切り切断刃を配する横切り切断ユニットを少なくとも１つ以上備えて、前記横切り切断ユニットによって切り出された細帯状豆腐生地を搬送する豆腐生地搬送装置を備えて、前記細帯状豆腐生地の少なくとも２行分を列方向に切断する縦切り切断刃を行方向に少なくとも１枚以上備え列方向に沿って切断するように配設した縦切り切断ユニットを備えることを特徴とする。
本発明によれば、前記シート状豆腐生地から横切り切断ユニットによって少なくとも２行分の細帯状豆腐生地を切り出して、豆腐生地搬送装置によって該細帯状豆腐生地を下流側に搬送して、縦切り切断ユニットによって該豆腐生地搬送装置上の該細帯状豆腐生地を最小単位の豆腐生地に切断し、少なくとも２行以上の行列状に配列した最小単位の豆腐生地に切断することができる。従来のように前記細帯状豆腐生地１行毎に最小単位の豆腐生地を切り出す方法に比べて、同じ切断処理能力においては縦切り切断ユニットの動作の１サイクル所要時間が２倍以上になり時間的余裕ができ、縦切り切断ユニットの機械寿命を延ばすことができる。また同じ１サイクルの所要時間においては搬送装置（搬送コンベア）の増速が可能であれば、縦切り切断処理能力は２倍以上に高めることが可能になる。 本発明では、前記縦切り切断刃や前記位置決め部材の昇降動作や水平動作、回動動作などは特に精密な制御が設定できるよう、エアシリンダ、油圧シリンダ、水圧シリンダでもよいが、電動シリンダ、ロボシリンダ（ＩＡＩ製）などの、数値設定できるリニアアクチュエータが好ましい。あるいは位置決め部材が回動する形態であっては、チェーンとスプロケットやベルトとプーリー等を介して昇降動作や水平動作させる形態であってもよい。インバータ設定や近接スイッチや接触・非接触センサーの組み合わせでの制御でも良いが、ロータリーエンコーダやサーボモータ、ステッピングモータ、ロボットなど正確に数値設定できる方が好ましい。それによって再現よく正確な機械動作を実現しやすく、切断処理能力を限界まで向上させることができる。
本発明によれば、複数行の前記細帯状豆腐生地をひとまとめにして一斉に切断することによって、切断処理能力を大幅に向上させることができる。ここで縦切り切断刃は、中華包丁型切断刃のような刃渡りの長い押し切りの刃が好ましいが、引き切りするナイフ型切断刃（包丁型、刃渡りは少なくとも豆腐生地の高さより長い。）や円形切断刃（ロールカッターともいう。好ましくは搬送装置（コンベア）と同調し回転しながらか、搬送装置（コンベア）上を列方向に水平・上下に走査させて、刃の重みで押し切るようにして、また小径よりも大径の円形刃が好ましい。）などの形状を有し、それら縦切り切断刃が列方向に沿って切断するように、行方向に多数、等間隔に配設された形態である。両端の生地耳を取り除く場合は、その行方向の豆腐生地最小単位数（Ｎ）に１つ加えた数（Ｎ＋１）枚の切断刃を備える。両端の生地耳を除かない場合はその行方向の豆腐生地最小単位数（Ｎ）から１つ差し引いた数（Ｎ−１）枚の切断刃を備える。前記中華包丁型切断刃の場合は複数行の細帯状豆腐生地に接するような刃長を有し、昇降機構を備えた縦切り切断ユニットによって上昇・下降する動作を行い複数行の細帯状豆腐生地を一斉に同時に切断する。その後、搬送ベルトを傷つけぬよう少し上昇した後に行方向に移動して、１個分の豆腐生地の間隔を等間隔に広げる動作を行ってもよい。前記ナイフ型切断刃の縦切り切断ユニットの場合、回転軸に多数のナイフ形切断刃を備えて列方向に回動ないし水平・上下動作することによって、停止中の搬送装置（コンベア）上にある複数行の細帯状豆腐生地を下流側から上流側へ（ないしはその逆）順に一気に１回の引き動作によって切断する。または回転軸に多数のナイフ形切断刃を備えて列方向に回動し、搬送装置（コンベア）によって複数行の細帯状豆腐生地を一回の動作で順次に（ほぼ同時に）切断する形態であってもよい。また前記ナイフ型切断刃の縦切り切断ユニットの場合、昇降機構によって上下して、水平動作機構によって引き切りするか、搬送装置（コンベア）で進行する複数行の細帯状豆腐生地を一気に切断する形態であってもよい。円形切断刃の縦切り切断ユニットの場合、軸が基台に固定されて回転刃は遊動回転して搬送装置（コンベア）によって進行する豆腐生地を切断する形態でもよいが、昇降動作機構や水平動作機構を備えて、停止中ないし駆動中の搬送装置（コンベア）上にある複数行の細帯状豆腐生地に対して、下降して列方向に水平移動して円形切断刃を転がすように下流側から上流側へ（ないしはその逆）一気に１回の動作で引き切るように切断してもよい。また縦切り切断刃はある範囲で遊動するようにして一定方向の周回するように配設した動作の中で、搬送装置上の複数行の細帯状豆腐生地を順次切断するようにしてもよく、搬送装置と同調、同期するようにすると、機構的にもシンプルかつメンテナンスや故障・異物混入等のリスクを軽減する。また周回動作の中で切断刃の洗浄工程を設けることで常に衛生的な状態を保つことが可能になる。なおナイフ形切断刃や円形切断刃の場合、切断後の横移動や横開き動作はなく、切断された１個分の豆腐生地の行方向の間隔を開く工程は、後工程で、２つの間隔調整コンベアに移載してその速度差で間隔を開く機構や、駆動する搬送コンベア上で各１個分の豆腐生地を進行させながら行方向に１個おきにストッパを効かせて交互に列方向にずらして、１個分に相当する距離を行方向に開く千鳥式分配機構や、行方向に横開きする板上に移載して行方向の間隔を等間隔に開く機構であってもよく、特に限定しない。
（７）本発明としては、上記（６）の豆腐生地の切断装置において、前記縦切り切断ユニットと連動して、前記細帯状豆腐生地を各々列方向及び／又は行方向で予め位置決めする位置決め部材を有する位置決めユニットを備えることを特徴とする。
本発明によれば、縦切り切断工程において、予め位置決め手段により位置決めして正確な切断を行うことができる。その位置決めは縦切り切断工程で切断直前に行うか、ないしは前工程の切断工程の直後、細帯状豆腐生地の行間の間引きに用いた前工程の切断刃によって押し送る動作と兼ねてもよく、前工程の切断工程における前工程の位置決め手段によって予め位置決めされて縦切り切断工程の位置で細帯状豆腐生地から離れた後に縦切り切断刃で切断される形態であってもよい。また位置決めする方向は列方向や行方向で、両側ないしは片側一方からの位置決めであってもよい。ここで搬送コンベアで位置が変わらないように縦切り切断工程に搬送される形態が好ましい。
（８）本発明としては、上記（７）の豆腐生地の切断装置であって、前記位置決め部材が前記縦切り切断刃と直交する方向（行方向）に配設し、前記第２の位置決め部材が前記細帯状豆腐生地の上流端及び／又は下流端に接して列方向に挟むように位置決めをする位置決め部材であることを特徴とする。
即ち、本発明では細帯状豆腐生地を最小単位の１個分の豆腐生地に切断する縦切り切断刃と直交する方向（行方向）に位置決め部材が配設されて、細帯状豆腐生地の上流側の端面及び／又は下流側の端面に接して、列方向の位置決めを行う形態であって、特に温かく柔らかい細帯状豆腐生地の長手方向が歪みやすいことからそれを修正するために好ましい形態である。また縦切り切断工程において後述の（９）の発明との併用によって四方から位置決めをしてより一層正確に縦切り切断工程の切断を行うことができるので好ましい形態である。なお、縦切り切断工程の前工程から細帯状豆腐生地を押し送る際に用いる押し送り板を上流側の位置決め部材として代用する形態であってもよい。

（９）本発明としては、上記（７）の豆腐生地の切断装置であって、前記位置決め部材が前記縦切り切断刃と平行（列方向）に配設し、前記位置決め部材が前記細帯状豆腐生地の左端及び／又は右端に接して行方向に挟むように位置決めをする位置決め部材であることを特徴とする。
即ち、本発明では細帯状豆腐生地を最小単位１個分の豆腐生地に切断する縦切り切断刃と平行な位置決め部材が細帯状豆腐生地の下流に向かって右側の端面及び／又は左側の端面に接して行方向の位置決めを行い、縦切り切断工程において生地耳量を一定にするか、または生地耳を出さずにロスを最小限に抑えるべく、縦切り切断工程の位置決めの前に予め補助的な位置決めを行っておくこと（段階的な位置決め）も好ましい。また縦切り切断工程において前述の（８）の発明との併用によって四方から位置決めをすることより一層正確に縦切り切断工程を行うことができるので好ましい形態である。
また特に温かく柔らかい細帯状豆腐生地は特に陸上では特に自重によるダレの現象があり（半水中でもある程度起こりうる）、行方向に細長い帯状豆腐生地においては中央付近に比べて行方向の両端付近の豆腐生地が外側に広がり、生地耳が増えるとともに、厚みが薄くなる傾向にある。本発明ではそのようなダレ現象が製造条件（大豆、豆乳、凝固条件等）によって変化しても一定でかつ均一な寸法を維持できる効果がある。
本発明によれば、例えば、細帯状豆腐生地から１個分のサイズまでに切断する縦切り切断工程の直前までに少なくとも前記細帯状豆腐生地の行方向の定位置状態を整えるようにすることによって、大幅に切断精度が低くなることを避けることができる。また温かく柔らかい細帯状豆腐生地を大きな塊として比較的素早く移送しても、また次の搬送や切断する場所が水中ないしは半水中ないしは陸上であっても、移送する際の豆腐の歪みや変形や欠けを最小限に防止できる。パック詰め等に必要な所定の大きさの豆腐生地になるように列方向に切断する（縦切り切断工程）際も、機械的動作時間にゆとりができることにより、結果的に豆腐の歪みや変形や欠けを防止した状態で切断処理能力を向上させて、１個単位の大きさに正確に効率的に切断することができる。またロスを軽減し、生産ラインの歩留りを向上させ、製品原価を下げる経済的な効果も期待できる。また１動作で多数分の豆腐生地を切断するので、生産量あたりの動作回数を減らせるため機械的な寿命を延長し、メンテナンスの管理負担を軽減する効果も期待できる。また本発明によれば、生地耳としてのロスを最小限ないしはゼロにする効果も期待できる。

すなわち前記横切り切断工程によって切り出された細帯状豆腐生地を後の縦切り切断工程に送り出す工程で、その送り出し機構が細帯状豆腐生地の上流端面に接して位置決めする位置決めを代用する形態である。本発明では、細帯状豆腐生地が水中にあるか、又は、前記縦切り切断工程以降において陸上に引き上げられた細帯状豆腐生地であることが好ましく、その際に上下１８０度反転させる反転工程を介して、その反転枠から細帯状豆腐生地を送り出す送り出し機構であってもよい。本発明では段階的な切断工程において、前工程の送り出し機構を次工程の位置決めにも兼用するので、機械的機構（部品点数）を減らし、装置コストを低く抑え、洗浄部品も減らし作業性を向上させ、メンテナンスの管理負担を軽減させる効果が期待できる。
以上、本発明（１）〜（１０）によれば、例えば、シート状豆腐生地から１個分のサイズまでに切断する各切断工程、すなわち行方向に切断する横切り切断工程や列方向に切断する縦切り切断工程の直前までに少なくとも前記細帯状豆腐生地の列方向及び／又は行方向の定位置状態を整えるようにすることによって、その定位置状態を修正して、大幅に切断精度が低くなることを避けることができる。また温かく柔らかい豆腐生地を比較的ゆとりを持って移送しても処理能力が向上する。また次の搬送や切断する場所が水中ないしは半水中ないしは陸上であっても、移送する際の豆腐の歪みや変形や欠けを最小限に防止できる。パック詰め等に必要な所定の大きさの豆腐生地になるように列方向に切断する（縦切りの切断工程）際も、機械的動作時間にゆとりができることにより、結果的に豆腐の歪みや変形や欠けを防止した状態で切断処理能力を向上させて、１個単位の大きさに正確に効率的に切断することができる。また生地耳ロスを削減し、生産ラインの歩留りを向上させ、製品原価を下げる経済的な効果も期待できる。また１動作で多数分の豆腐生地を切断するので、生産量あたりの動作回数を減らせるため機械的な寿命を延長し、メンテナンスの管理負担を軽減する効果も期待できる。
また、本発明（１）〜（１０）によれば、縦切り切断工程で、陸上においても、豆腐生地の歪みを防止して綺麗に切断することができるが、水中（半水中を含む）の場合には、さらに安定した位置決め作用が生まれて、複数行の細帯状豆腐生地の歪みを防止して綺麗に切断することができる。また縦切り切断工程において、豆腐生地が陸上にあっても、豆腐生地の歪みを防止して綺麗に切断することができる上、よりゆとりをもって機械動作が可能になり、より高い処理能力を実現できる。

That is, in the present invention, a positioning member parallel to the longitudinal cutting blade for cutting the strip-like tofu dough into the minimum unit of tofu dough is located on the right end face and / or the left end face toward the downstream of the strip-like tofu dough In order to position the row direction in contact and to make the amount of cloth ears constant in the vertical cutting process or to minimize the loss without putting out the cloth ears, the auxiliary cutting is previously performed prior to the positioning of the vertical cutting process It is also preferable to perform various positioning (stepwise positioning). In addition, in the longitudinal cutting step, the longitudinal cutting step can be performed more accurately by positioning from four directions by using the invention of the above (8) in combination, which is a preferable embodiment.
In addition, particularly warm and soft stripy tofu dough has a phenomenon of sagging particularly due to its own weight on land (it may occur to some extent in half water), and elongated tofu strips in tow direction have tofu near both ends in the row direction compared to near the center. The dough spreads outward, and as the dough ears increase, the thickness tends to be thinner. In the present invention, even if such a dripping phenomenon changes according to manufacturing conditions (soybean, soy milk, coagulation conditions, etc.), there is an effect that uniform and uniform dimensions can be maintained.
According to the present invention, for example, by arranging at least the fixed position of the strip-like tofu dough in the row direction until just before the longitudinal cutting process of cutting the strip-like tofu dough into a size for one piece , It can be avoided that the cutting accuracy drops significantly. Also, even if the warm and soft stripy tofu dough is relatively quickly transferred as a large mass, and the place to be transported or cut next time is underwater or half water or on land, distortion, deformation or chipping of tofu during transfer. Can be minimized. Even when cutting in the column direction (longitudinal cutting process) to form tofu dough of a predetermined size necessary for packing etc., distortion and deformation of tofu can be obtained as a result by being able to relax mechanical operation time. The cutting capacity can be improved while preventing chipping, and cutting can be performed accurately and efficiently to the size of one unit. In addition, it is possible to reduce the loss, improve the yield of the production line, and to reduce the cost of the product economically. In addition, since a large number of portions of tofu dough are cut in one operation, the number of operations per production amount can be reduced, so that the mechanical life can be extended and the effect of reducing maintenance management burden can be expected. Further, according to the present invention, the effect of minimizing or eliminating the loss as the material ear can also be expected.
(10) The apparatus for cutting tofu dough according to the above (7) according to the present invention, wherein the plurality of thin band-like thick band tofu dough in water, semi water or land is cut longitudinally on land The apparatus is characterized by comprising a delivery mechanism for delivering in the process, and the delivery mechanism also serves as positioning means for positioning the upstream end of the strip-like tofu dough in the longitudinal cutting process.
That is, in the step of feeding the strip-like tofu dough cut out in the cross-cutting step into the later vertical cutting step, the delivery mechanism substitutes the positioning for positioning in contact with the upstream end face of the strip-like tofu dough. In the present invention, it is preferable that the strip-like tofu dough is in water or a strip-like tofu dough pulled up to land after the above-mentioned longitudinal cutting step, and in that case, through a reversing step of reversing 180 degrees up and down. Alternatively, it may be a delivery mechanism for delivering the strip-like tofu dough from the inverted frame. In the present invention, since the delivery mechanism of the previous step is also used for positioning of the next step in the stepwise cutting process, the mechanical mechanism (number of parts) is reduced, the apparatus cost is reduced, the number of cleaning parts is reduced, and the workability is improved. Can be expected to reduce the maintenance burden.
As described above, according to the present inventions (1) to (10), for example, each cutting step of cutting sheet-like tofu dough into pieces of one size, ie, a transverse cutting step of cutting in the row direction and cutting in the column direction By adjusting the fixed position of at least the strip-like tofu dough in the row direction and / or the row direction just before the vertical cutting process, the fixed position condition is corrected and the cutting accuracy is significantly lowered. You can avoid that. In addition, the transferability of the warm and soft tofu dough can be improved relatively well. In addition, even if the place to be transported or cut next time is underwater, semi-underwater or on land, distortion, deformation or chipping of tofu during transfer can be minimized. Even when cutting in the column direction (longitudinal cutting process) so that the tofu material of a predetermined size necessary for packing etc. can be relaxed in mechanical operation time, distortion or deformation of tofu as a result The cutting processing ability can be improved while preventing chipping and cutting can be performed accurately and efficiently in the size of one unit. In addition, it is possible to reduce the material ear loss, to improve the yield of the production line, and to reduce the cost of the product economically. In addition, since a large number of portions of tofu dough are cut in one operation, the number of operations per production amount can be reduced, so that the mechanical life can be extended and the effect of reducing maintenance management burden can be expected.
Moreover, according to the present inventions (1) to (10), distortion of tofu dough can be prevented and the cut can be finely performed on land also in the vertical cutting process, but in water (including half water) In this case, a more stable positioning action can be produced to prevent distortion of a plurality of rows of strip-like tofu dough and to cut cleanly. In the longitudinal cutting process, even if the tofu dough is on land, it is possible to prevent distortion of the tofu dough and cut it cleanly, and machine operation becomes possible with more ease, and higher processing capacity can be realized .
本発明ではシート状豆腐生地から横切り切断で得られた少なくとも２行以上の細帯状豆腐生地をまとめて１回の動作で最小単位の豆腐生地に切断することを特徴とする。また列方向ないし行方向で細帯状豆腐生地の位置決めをした後、縦切り切断で列方向に１個分の製品ごとに１回の動作で切断して、その後列間を広げて列方向で位置決めする形態であってもよく、前記同様に豆腐の変形や欠けを防止した状態でライン全体の能力を向上させて、正確に速く効率的に切断することができるとともに、生産ラインの歩留りを向上させ、製品原価を下げる経済的な効果も期待できる。 The present invention is characterized in that at least two or more rows of strip-like tofu dough obtained by cutting across a sheet-like tofu dough are cut together into a minimum unit of tofu dough in one operation. Also after the positioning of the strip-like tofu cloth in the column direction or the row direction, it is cut in one operation in the column direction by vertical cutting cut of every 1 minute of product, positioning in the column direction with open between the rear row In the same manner as described above, the capability of the entire line can be improved while preventing deformation and chipping of tofu, so that accurate and efficient cutting can be performed, and the yield of the production line can be improved. The economic effect of lowering product costs can also be expected.
本発明によれば、複数行分の細帯状豆腐生地からパック詰めする１個分の大きさになるように列方向に切断する縦切り切断工程において、縦切り切断工程に対応する位置決め手段を設けることにより豆腐の変形を防止した状態で正確にかつ効率的に切断することができる。また、ロス軽減と歩留まり向上が可能になり、高い処理能力の機械において各機械動作をゆっくり、かつ、動作回数を減らすことにより機械装置のメンテナンス軽減と機械寿命を延ばすことができる。また水槽の水に晒す工程が存在しても、水中にある豆腐生地は太帯状豆腐生地であり、表面積が少ないため、離水が生じ難く、味が抜ける事態や雑菌が付着して汚染する事態を抑制した状態で切断することができる。また前記位置決め手段（細帯状豆腐生地の上流側ないしは下流側、又は下流方向に見て左側ないしは右側の位置決め手段）、又は、縦切り切断刃によって切断する際、位置決め部材の接触・押圧による歪みや変形発生を効果的に防止することができる。 According to the present invention, positioning means corresponding to the longitudinal cutting step is provided in the longitudinal cutting step of cutting in the column direction so as to be one pack size packed from a plurality of rows of strip-like tofu dough Thus, it is possible to cut the tofu accurately and efficiently while preventing deformation of the tofu. In addition, loss reduction and yield improvement can be achieved, and machine maintenance can be reduced and the machine life can be extended by reducing the number of operations slowly and reducing the number of operations in a high throughput machine. Also, even if there is a process of exposing the tank to water, the tofu dough in the water is a thick band-like tofu dough and has a small surface area, so it is difficult to cause water separation, and the taste disappears or miscellaneous bacteria adhere and contaminate. It can be cut in a suppressed state. In addition, when cutting by the positioning means (upstream or downstream side of the strip-like tofu dough, or positioning means on the left or right as viewed in the downstream direction) or longitudinal cutting blade, distortion due to contact or pressure of the positioning member or The occurrence of deformation can be effectively prevented.
また、本発明によれば、縦切り切断工程の機械的動作に要する許容時間が拡大できて、切断工程の切断処理能力を大幅に向上することができる。シート状の豆腐生地から、最小単位の１個分の豆腐生地までに効率よく切断できる。従って豆腐類の連続凝固成型・切断ライン全体では、従来のように１行ごとの縦切り切断工程（２，０００〜３，０００丁／ｈ）と比較して、２倍（５，０００〜８，０００丁／ｈ）ないしは数倍の能力（１０，０００〜３６，０００丁／ｈないしはそれ以上）にすることが可能になる。 Further, according to the present invention, the allowable time required for the mechanical operation of the vertical cutting process can be expanded, and the cutting capacity of the cutting process can be significantly improved. It can be efficiently cut from sheet-like tofu dough to a minimum unit of tofu dough. Therefore, the entire continuous curd shaping / cutting line for tofu is twice (5,000 to 8) as compared to the conventional longitudinal cutting process (2,000 to 3,000 c / h) for each row. It is possible to make it possible to have a capacity of from 1,000, 000 / h to several times (10,000 to 36,000 / h or more).

(Cutting process of tofu dough)
FIG. 1 is a view for explaining a cutting process 50 of tofu dough T to which the present invention is applied. Block-like or sheet-like (belt-like) tofu dough T (hereinafter collectively referred to as sheet-like tofu dough) continuously or intermittently formed by the upper and lower conveyors is transported by the transport conveyor C 1 to the water tank W In the water tank W, the first cutting device 51 cuts into a plurality of rows of thick band-like tofu dough T1 having at least two rows, is lifted in the reversing step H (or 20), and is delivered to the transport conveyor C2. Be Then, after being cut into a plurality of rows of strip-shaped tofu dough T2 in the second cutting step 52 of cutting in the row direction with one row width for packing, the minimum unit of one portion of tofu dough T3 After being cut in the row direction by the vertical cutting device 53, the product is packed. In the automatic production line 1 of tofu according to the present embodiment, the sheet-like tofu dough T is transported from the land to the water by the transport conveyor C1, and in the first cutting step 51 in the direction orthogonal to the transport direction of the transport conveyor C1. Block-like tofu dough T1 (corresponding to a plurality of rows) having a length of N pieces (N columns in the row direction) and a length of M pieces (M rows in the column direction) in the product size conveying direction The product is cut into one row of long band-like large-sized tofu dough), inverted by a reverse processing apparatus H, and divided in a second cutting step 52 into M equal lengths of M pieces of tofu dough T1 in the column direction It has a length of one product size (one side) and a length of N pieces in the row direction (this length may be the length of the material ears at both ends added). Strips of tofu dough having the same size are cut into M in units of one row, and then the transport direction of the transport conveyor C2 (column direction) It is shredded into N pieces in one product size (longitudinal cutting in the column direction) and divided into M × N pieces, for example, 2 pieces in 10 rows by a total of 20 pieces in 10 columns, and a predetermined interval The tofu dough T3 which has been spread and aligned is transported, and a pack transport conveyor of a packaging pack which collectively transports and transports a total of 20 packs in 10 rows for 2 rows and 10 transports in a direction orthogonal to the transport direction. The tofu dough T3 is packed at once (land-packed). M and N are positive integers. The transfer destination by the transfer conveyor C2 is packed by the packing conveyor C3 for transferring the pack group (two-row pack group) so as to intersect the transfer conveyor C2, and the process moves to the next step. In the present application, the advancing direction of each conveyor is taken as the column direction, and the direction orthogonal to the advancing direction is taken as the row direction.
（第１の横切り切断と反転工程）
まず、豆腐の自動製造ライン図１では、全ては図示しないが、成形装置の出口側の搬送コンベアＣ１から連続的ないしは断続的に成形される連続するシート状又は断続するブロック状の態様で排出される豆腐生地Ｔは、晒し水（常温の井戸水、水道水ないしはそれに次亜塩素酸水やクエン酸・グルコン酸等の食品用有機酸等を含む水、又は１００℃以下のお湯）を満たした水槽Ｗに導かれ、豆腐生地Ｔのホエーやアク成分を洗い落とし、冷却又は加熱して少なくとも表面を少し硬化させ損傷しにくく布離れをよくするか、又は、表面殺菌を施して、水槽Ｗ中において浮力を利用して豆腐生地Ｔを損傷させずに押し送りしながら、順次に第１の行方向の切断工程５１が実施される。第１の行方向切断は、豆腐生地Ｔを自動製造ラインの幅方向（行方向又は搬送方向に対して直交方向）に切断して、反転処理に適する大きさの太帯状豆腐生地Ｔ１にする。なお、一般に柔らかな豆腐に無理な力が掛かった状態で切断すると、切断後、歪んだ形状になってしまうが、一旦水槽Ｗに導入するのは搬送時のシート状豆腐生地Ｔの歪み（膨らみ）を抑えて、所定サイズの良好な切断状態を得る効果があり、またシート状豆腐生地Ｔを濾布から剥離させやすくする効果や、水質によっては表面に付着した雑菌の除去や殺菌効果もある。
豆腐生地の反転処理装置Ｈは、豆腐生地Ｔ１を収納するケージ２Ｋを反転するケージ反転機構２０と、豆腐生地Ｔをケージに押し込む送り込み機構１０と、豆腐生地Ｔをケージ２Ｋから排出するための押し出し機構３０とからなり、豆腐の自動製造ラインの途中に配置され、豆腐の自動製造ライン中において太帯状豆腐生地Ｔ１を反転する役割を分担する（図１）。同図中の矢印は、豆腐の自動製造ラインの流れ方向を示し、同図の左手方向が上流側であり右手方向が下流側である。なお本発明では太帯状ないしは細帯状豆腐生地についての反転処理装置Ｈが介在しない形態であってもよいが、以下反転処理装置Ｈが介在する形態を中心に述べる。
水槽Ｗの上流側には、連続成型機の下側コンベアである搬送コンベアＣ１の終端が水面下に漬かる形に配設し、その搬送コンベアＣ１に続いて、第１の横切り切断工程５１を備えて、水槽Ｗには横切りされた２行分に相当する太帯状豆腐生地Ｔ１を押し送る送り手段Ｃ５１ａ（図示なし）と該太帯状豆腐生地Ｔ１を案内する水平仕切り板Ｃ５１を備えた搬送装置Ｃ５１が設置されている形態でも良い。好ましくは複数の送り手段Ｃ５１ａの搬送方向又は上下方向の動作により豆腐生地Ｔ１を下流方向位に順次前進させる。特に搬送装置Ｃ５１がコンベアベルト式搬送装置６０であってもよく、コンベアベルト式搬送装置６０が、搬送方向に循環駆動され、搬送コンベアＣ１から送り込まれた太帯状豆腐生地Ｔ１を下流側に搬送する形態であってもよい。水槽Ｗの水面下には、上流側から押し送りされてくる該太帯状豆腐生地Ｔ１の姿勢を水平に制御しながら該太帯状豆腐生地Ｔ１を案内する水平仕切り板Ｃ５１が設置される。前記水平仕切り板５１の上面やコンベアベルト式搬送装置６０のベルト上面は下流方向に少しずつ高さが下がるよう下り勾配や所定の高低差が設定されている。特に硬い豆腐質の製品では成型機の下側コンベアである搬送コンベアＣ１とは別にコンベアベルト式搬送装置６０を設けると、成型機の下布を水槽Ｗに漬け込まないように、全て陸上で搬送、切断、反転ができて、水槽中の豆腐粕や雑菌を下布や製品に付着することを防止できるので好ましい。コンベアベルト式搬送装置６０や、搬送コンベアＣ１の移動に合わせて反転機構２０や反転ケージ２Ｋや押し出し機構３０が介在して連動してもよい。
ここで２行分に相当する太帯状豆腐生地Ｔ１は２行以上分に相当の太帯状豆腐生地Ｔ１であってもよく、又は、太帯状豆腐生地に代わって１行ないしは２行以上の細帯状豆腐生地Ｔ２に置き換えた形態であってもよい。ここで例示する第１の横切り切断の形態以外には、切断手段、切断刃形状・材質・表面加工や分割ないし２枚重ねした切断刃等の構成、切断機構などの形態は特に限定しない。 反転処理装置Ｈは、水槽Ｗの下流側の終端部に配置されている。反転処理装置Ｈの作動範囲は、水槽Ｗの終端部から搬送コンベアＣ２の上流側の端部に及ぶものであり、反転処理装置Ｈは、第１次の横切り切断作業を経た太帯状豆腐生地Ｔ１の表裏を反転するとともに、太帯状豆腐生地Ｔ１を水槽Ｗから水上（空中）の搬送コンベアＣ２へ陸上げする（特許文献８）。この陸上げのとき押し出し機構３０がその櫛歯状の板で太帯状豆腐生地Ｔ１の後方側から押してケージ２Ｋから太帯状豆腐生地Ｔ１を押し出す。一般に型箱や連続成型機による木綿豆腐の成型工程では、太帯状豆腐生地Ｔの上布面はアバタ状や凹凸ができる傾向があり、下布面の方が商品としては見栄えがよくなる傾向があるため、反転してパック詰めすることがある。また、特に木綿豆腐の連続自動ラインでは、下布面の状態（異物の付着がないか、損傷していないか等の異常）を目視しにくいため、反転することで目視ないしはカメラで検査できるようにすることが重要である。ここで太帯状豆腐生地Ｔ１の反転以外に、細帯状豆腐生地Ｔ２を反転する形態であってもよい。またここで例示する反転機構形態以外には反転手段、反転機構などは特に限定しない。
(First cross cutting and reversing process)
First, the automatic production line of tofu, although not shown in the drawing, is discharged from the conveyer C1 on the outlet side of the forming apparatus in the form of a continuous sheet or an intermittent block shaped continuously or intermittently. Tofu dough T is a water tank filled with bleached water (well water at normal temperature, tap water, or water containing organic acids for food such as hypochlorous acid water, citric acid, gluconic acid, etc., or hot water at 100 ° C. or less). It is introduced to W, and the whey and oysters of tofu dough T are washed away, cooled or heated to at least cure the surface a little to make it hard to damage or improve the release of the cloth, or surface disinfected to be buoyant in the water tank W The first row cutting step 51 is sequentially performed while pushing the tofu dough T without damaging it. In the first row direction cutting, the tofu dough T is cut in the width direction (the row direction or the direction orthogonal to the transport direction) of the automatic production line to form a thick band-like tofu dough T1 having a size suitable for reverse processing. In addition, if it cuts in the state where force was applied to the soft tofu in general, it will become a distorted shape after cutting, but once it is introduced into the water tank W, the distortion of the sheet-like tofu dough T at the time of conveyance Has the effect of obtaining a good cut state of a predetermined size, and also has the effect of making sheet-like tofu dough T easy to peel off from the filter cloth, and depending on the water quality there is also a removal of germs attached to the surface and a bactericidal effect .
Inversion processing apparatus H of tofu dough includes cage inversion mechanism 20 for reversing cage 2K for storing tofu dough T1, feeding mechanism 10 for pushing tofu dough T into the cage, and extrusion for discharging tofu dough T from cage 2K. It consists of a mechanism 30 and is disposed in the middle of an automatic production line of tofu, and in the automatic production line of tofu, it shares the role of inverting the thick band-shaped tofu dough T1 (FIG. 1). The arrow in the figure shows the flow direction of the automatic manufacturing line of tofu, the left-hand direction of the figure is the upstream side, and the right-hand direction is the downstream side. In the present invention, the reverse processing apparatus H may not be used for thick band-like or strip-like tofu dough, but the following description will focus on a form in which the reverse processing apparatus H intervenes.
On the upstream side of the water tank W, the end of the conveyer C1, which is the lower conveyer of the continuous forming machine, is disposed so as to dip below the water surface, and following the conveyer C1, the first cross cutting step 51 is provided. The transport apparatus C51 includes a feeding means C51a (not shown) for pushing the large band of tofu dough T1 corresponding to two rows cut across the water tank W and a horizontal partition C51 for guiding the large band of tofu dough T1. May be installed. Preferably, the tofu dough T1 is sequentially advanced in the downstream direction by the movement of the plurality of feeding means C51a in the transport direction or the up-down direction. In particular, the conveying device C51 may be a conveyor belt type conveying device 60, and the conveyor belt type conveying device 60 is driven to circulate in the conveying direction and conveys the large band tofu dough T1 fed from the conveying conveyor C1 downstream. It may be in the form. Below the water surface of the water tank W, a horizontal partition plate C51 for guiding the large band tofu dough T1 while horizontally controlling the posture of the large band tofu dough T1 pushed from the upstream side is installed. A downward slope and a predetermined height difference are set such that the height of the upper surface of the horizontal partition plate 51 and the belt upper surface of the conveyor belt type conveying device 60 is gradually lowered in the downstream direction. Especially in the case of hard tofu products, if a conveyor belt type conveyor 60 is provided separately from the conveyor C1 which is the lower conveyor of the molding machine, all the conveyance is carried on land so that the lower cloth of the molding machine is not soaked in the water tank W It is preferable because it can be cut and inverted to prevent tofu and bacteria in the water tank from adhering to the lower cloth and the product. The reversing mechanism 20, the reversing cage 2K, and the pushing mechanism 30 may intervene and interlock with the movement of the conveyor belt-type transfer device 60 and the transfer conveyor C1.
Here, the thick band tofu dough T1 corresponding to two lines may be a thick band tofu dough T1 corresponding to two or more lines, or, in place of the large band tofu dough, one strip is two or more lines It may be replaced with tofu dough T2. There are no particular limitations on the form of the cutting means, the shape of the cutting blade, the material, surface processing, the configuration of the cutting blade or the like divided or overlapped, the cutting mechanism, etc., other than the first transverse cutting form exemplified here. The reverse processing device H is disposed at the downstream end of the water tank W. The operation range of the reverse processing device H extends from the end of the water tank W to the upstream end of the conveyer C2, and the reverse processing device H has a large cross-cut tofu dough T1 that has undergone the first cross cutting operation. Reverse the front and back, and lift up the thick tofu dough T1 from the water tank W to the transport conveyor C2 on water (in the air) (Patent Document 8). At the time of landing, the pushing mechanism 30 pushes the thick band tofu dough T1 from the rear side of the large band tofu dough T1 with its comb-like plate and pushes out the large band tofu dough T1 from the cage 2K. In general, the upper cloth surface of the thick band-shaped tofu dough T tends to have an avatar-like shape and irregularities, and the lower cloth surface tends to look better as a product in the molding process of cotton tofu using a mold box or a continuous molding machine. Because of this, they may be flipped and packed. In addition, in the continuous automatic line of cotton tofu in particular, it is difficult to visually check the condition of the lower cloth surface (abnormality such as adhesion of foreign matter, damage etc.), so it is possible to inspect by visual inspection or camera by reversing. It is important to Here, in addition to the inversion of the thick tofu dough T1, the thin tofu material T2 may be reversed. Further, the reversing means, the reversing mechanism, etc. are not particularly limited other than the reversing mechanism form exemplified here.
（第２の横切り切断工程）
反転処理によって少なくとも２行分の太帯状豆腐生地Ｔ１は、陸上の搬送コンベアＣ２に陸上げされて送られて、搬送コンベアＣ２上で第２の切断工程と第３の縦切り切断工程を経てパック詰め装置の方向に向かって搬送される（図１）。
図２は、行方向の第２の切断工程の斜視図であり、図４は行方向に切り離す第２の切断工程を説明する側面図である。第２の切断刃３ａと、第２の切断刃３ａを駆動する上下動シリンダを有する行方向切断刃ユニット３を備え（図２（ａ）、図４（ａ））、第２の切断刃３ａは、下降して前記搬送コンベアＣ２上に２行分の太帯状豆腐生地Ｔ１を停止させる下流側位置決め手段２ａで停止させた状態で複数行・複数列分の太帯状豆腐生地Ｔ１の中央を行方向で細帯状豆腐生地Ｔ２１、Ｔ２２に切断する（図２（ｂ）（ｃ）、図４（ｂ））。図４中符号７は、第２の切断刃３ａと下流側位置決め手段２ａとを搬送方向に駆動するシリンダ７である。これらは後述する吊り下げ駆動機構４０（図８〜図１０参照）により駆動するが、下流側位置決め手段２ａは、シリンダを有するユニット２により昇降動作され、第２の切断刃３ａを昇降するユニット３と同期的に駆動する。そして、下流側位置決め手段２ａと第２の切断刃３ａとで切断した先頭（１行目）の細帯状豆腐生地Ｔ２１を挟んだ状態で前方（パック詰め装置側）に向かって送り出す機構になっている。これにより、２行目の細帯状豆腐生地Ｔ２２との列方向の間隔が広げられて整列される（図２（ｄ）（ｅ）、図４（ｃ））。
(2nd crossing cutting process)
At least two lines of thick band-like tofu dough T1 are landed on the land conveyor C2 by inversion processing and sent, and are subjected to the second cutting process and the third vertical cutting process on the conveyor C2 to pack them It is transported in the direction of the filling device (Figure 1).
FIG. 2 is a perspective view of a second cutting step in the row direction, and FIG. 4 is a side view illustrating the second cutting step of separating in the row direction. A second cutting blade 3a is provided with a second cutting blade 3a and a row direction cutting blade unit 3 having a vertical movement cylinder for driving the second cutting blade 3a (FIGS. 2 (a) and 4 (a)). Is stopped by the downstream positioning means 2a that lowers and stops the large band of tofu dough T1 for two lines on the transport conveyor C2 while the center of the large band of tofu dough T1 for multiple lines and multiple columns is stopped It is cut into strips of tofu dough T21 and T22 in the direction (FIGS. 2 (b) and (c), FIG. 4 (b)). The code | symbol 7 in FIG. 4 is the cylinder 7 which drives the 2nd cutting blade 3a and the downstream positioning means 2a in the conveyance direction. These are driven by a suspension drive mechanism 40 (see FIGS. 8 to 10) described later, but the downstream positioning means 2a is moved up and down by the unit 2 having a cylinder to move up and down the second cutting blade 3a. Drive synchronously with And it becomes a mechanism which sends out toward the front (packing device side) in the state which pinched the strip shaped tofu dough T21 of the head (the 1st line) cut with the lower stream side positioning means 2a and the 2nd cutting blade 3a.

次に、搬送コンベアＣ２上の複数行の細帯状豆腐生地（図３５では４行の細帯状豆腐生地の例を示す）について、縦切り切断工程５３で、行方向に所定数のナイフ型縦切り切断刃２２ａを下降させて、上流に向かって列方向に水平移動しながら、下流側の細帯状豆腐生地Ｔ２１から、Ｔ２２、Ｔ２３を経て上流側の細帯状豆腐生地Ｔ２４まで１動作で短時間に順次に一気に切断して、最小単位の豆腐生地Ｔ３１、Ｔ３２、Ｔ３３、Ｔ３４に細断する（図３５（４）〜（５））。その後、ナイフ型縦切り切断刃２２ａは上昇して元の位置に戻るとともに、搬送コンベアＣ２から後工程のコンベア式のプレートＰ２への乗り移りの際に、両コンベアの速度差で各最小単位の豆腐生地Ｔ３の列方向の前後間隔を調整するようにしてもよい（図３５（６））。また本実施形態では各最小単位の豆腐生地Ｔ３の行方向の間隔を広げる手段としては、後述の千鳥分配整列式や速度分配整列式等が適用する。ナイフ以外に、ロールカッターの円板刃でも同様に行方向に切断しても良く、中華包丁型刃よりも豆腐生地接触面積を小さくして、付着物や微生物の混入リスクを軽減し、洗浄作業性も向上させることができる。
なお、縦切り切断刃は、板厚０．５〜１ｍｍ程度の薄く細く、傾斜した刃先を備えた材質で、切断時の切断抵抗を小さくして位置ずれを起こさないようにすることが好ましく、また刃先は搬送コンベアＣ２には接触しないか、接触しても損傷を避けるようにバネなどで軽く付勢するように遊動式にするとよい。
図３４と図３５では第２の横切り切断がない形態（太帯状豆腐生地を経ない形態）で、第１の横切り切断で細帯状豆腐生地４行同時に切り出す形態である。すなわち、第１の横切り切断工程５１で細帯状豆腐生地に横切り（行方向）して、第２の横切り切断工程５２を省略し、第３の縦切り切断工程５３に相当するナイフ型縦切り刃２２ａで縦切り（列方向）する。ナイフ型刃２２ａの動作方向は上流から下流でもその向きは問わない。なお、本形態においては第１の横切り切断工程５１で横切り切断刃で送り出すところで予め位置決めされて、その位置決め部材を兼ねる第１の横切り切断刃は細帯状豆腐生地から離れた状態として、縦切り切断が行われる。

本実施の形態は、水槽Ｗを用いず、陸上においてシート状豆腐生地Ｔから太帯状豆腐生地Ｔ１を切り出して、その太帯状豆腐生地Ｔ１の搬送方向の上流側及び下流側において位置決めをする上流側位置決め手段６ａと下流側位置決め手段２ａが配されており、複数行分（２行分）の太帯状豆腐生地Ｔ１の上流側及び下流側を位置決めした後、第２の切断刃３ａが下降動作して２行分の太帯状豆腐生地の中央を切断して細帯状豆腐生地Ｔ２１、Ｔ２２を得る（図１１、図１２）。
すなわち、陸上の上流側のプレート上で第１の切断刃１１ａにより、シート状豆腐生地Ｔから２行分の太帯状豆腐生地Ｔ１に切断されて、第１の切断刃１１ａにより搬送コンベアＣ２に送られると、下流側位置決め手段２ａが下降して待機しており、搬送される太帯状豆腐生地Ｔ１の下流側に接して静止させ、搬送コンベアも一旦停止する（図１２（１）〜（３）。次に上流側位置決め手段６ａが下降した後、次に上流側位置決め手段６ａが下流方向に横移動して太帯状豆腐生地を、下流側位置決め手段２ａとともに軽く挟持するか、又は一旦強く挟持して軽く挟持する（図１２（（４））。その後、豆腐生地を上流側と下流側で位置決めした状態で、第２の切断刃３ａが下降して豆腐生地の中央を切断し、搬送コンベアＣ２から少し離れて上昇する（図１２（５））。なお、上流側と下流側で位置決めした後、豆腐生地から位置決め手段が離れてから（上昇した後）、切断するようにしてもよい（第７の実施の形態参照。図１３、図１４））。

Sixth Embodiment
In the present embodiment, the large band tofu dough T1 is cut out from the sheet-like tofu dough T without using the water tank W, and the upstream side and the downstream side of the large band tofu dough T1 in the transport direction are positioned. The positioning means 6a and the downstream side positioning means 2a are arranged, and after positioning the upstream side and the downstream side of the large band of tofu dough T1 for a plurality of lines (two lines), the second cutting blade 3a is moved downward. The center of a thick band of tofu dough for two lines is cut to obtain a thin band of tofu dough T21 and T22 (FIGS. 11 and 12).
That is, the sheet-like tofu dough T is cut into two rows of thick band-like tofu dough T1 by the first cutting blade 11a on the plate on the upstream side of land, and is conveyed to the conveyer C2 by the first cutting blade 11a. Then, the downstream positioning means 2a descends and stands by, and is brought into contact with the downstream side of the thick band-like tofu dough T1 to be transported, and the transport conveyor is also temporarily stopped (FIG. 12 (1) to (3)) Next, after the upstream positioning means 6a is lowered, the upstream positioning means 6a moves laterally in the downstream direction to lightly pinch the thick band-like tofu dough together with the downstream positioning means 2a or hold it strongly once. Then, while the tofu dough is positioned on the upstream side and the downstream side, the second cutting blade 3a descends to cut the center of the tofu dough, and the conveyer C2 is moved. A little away from Ascending (Fig. 12 (5)) After positioning on the upstream side and downstream side, cutting may be carried out after the positioning means is separated (raised) from the tofu dough (the seventh embodiment) See form, Fig. 13, Fig. 14)).
When cut by the second cutting blade 3a, the second cutting blade 3a slightly raises and cuts the cut downstream strip-shaped tofu dough T21 to the downstream side, and the upstream strip-shaped tofu dough T22 And the interval between (Fig. 12 (6) to (7)). At this time, it is preferable that the downstream side positioning means 2a lightly clamp the narrow band-like tofu dough T21 in synchronization with the second cutting blade 3a, but it does not hold it and ascends first and retreats only with the cutting blade 3a A feed operation may be performed (not shown). At the time of the delivery operation, the conveyer may be stopped or synchronized and driven in synchronization. On the other hand, while the second cutting blade 3a is stopped after cutting, the conveyer C2 is driven, and in synchronization with it, the downstream positioning means 2a is also moved downstream to move the strip-shaped tofu dough T21 downstream. It may be moved to open a gap with the upstream strip-shaped tofu dough T22, and the downstream positioning means 2a may also rise and retract before the operation of the conveyer C2 in this case. After opening the space between the thin band-like tofu dough T21 and T22, the conveyer C2 is driven to be sent to the next process P2 (plate, conveyor, etc.), and the upstream positioning means 6a and the downstream positioning means 2a, The second cutting blade 3a returns to its original position and repeatedly performs the above operation while interlocking or in parallel. The downstream positioning means 2a may also perform an operation of extruding the cut strip-shaped tofu dough T22 into the downstream plate P2, and may also perform an operation of extruding the strip-shaped tofu dough T21.
（第７の実施の形態）
本実施の形態は、水槽Ｗを用いず、陸上においてシート状豆腐生地Ｔから太帯状豆腐生地Ｔ１を切り出して、その太帯状豆腐生地Ｔ１を下流側及び上流側位置決め手段２ａ，６ａが位置決めした後、太帯状豆腐生地Ｔ１から離れた状態して、第２の切断刃３ａが下降して、複数行分の太帯状豆腐生地Ｔ１から細帯状豆腐生地Ｔ２１、Ｔ２２に切断する形態である。本実施の形態としては、第２の切断の前に、予め豆腐生地Ｔ１の搬送方向の上流側及び下流側の両方で位置決め手段により位置決めしておいてから切断する（図１３、図１４）。
すなわち、陸上の上流側のプレートＰ１上で第１の切断刃１１ａにより、２行分の豆腐生地Ｔ１に切断されて、第１の切断刃１１ａにより搬送コンベアＣ２に送られると、予め下降していた下流側位置決め手段２ａが搬送されてくる２行分の太帯状豆腐生地Ｔ１を静止させて位置決めして、次に上流側位置決め手段６ａが下降した後に下流側に横移動して、下流側位置決め手段２ａと挟持するように位置決めをする（図１４（１）〜（４））。このとき豆腐生地の狭持と開放を２回以上繰り返して柔らかい豆腐生地の形の歪みや内部応力の歪みを修正するようにしても良い。
太帯状豆腐生地Ｔ１を上流側と下流側で位置決めした後、下流側位置決め手段２ａは下流側に移動し、同時に、上流側位置決め手段６ａが上流側移動して、太帯状豆腐生地Ｔ１から離れると、第２の切断刃３ａが下降して太帯状豆腐生地Ｔ１の中央を切断する（図１４（５）〜（６））。ここで、下流側位置決め手段２ａと上流側位置決め手段６ａが太帯状豆腐生地Ｔ１から離れる際上方に移動してもよい。第２の切断刃３ａは搬送コンベアＣ２のベルトを傷つけぬようにやや上昇して切断した下流側の細帯状豆腐生地Ｔ２１を静止している搬送コンベアＣ２のベルト上を滑らせながら（ないしは搬送コンベアＣ２を同調駆動させながら）下流側に所定の距離を押し出し動作して、上流側の細帯状豆腐生地Ｔ２２との所定の間隔に広げ整列させる。その際下流側位置決め手段２ａは上昇して退避してもよいが、上流方向に横移動して細帯状豆腐生地Ｔ２１を第２の切断刃３ａと軽く挟持して、その後の次工程Ｐ２への移載時に第２の切断刃３ａと同期・同調するようにしても良い。上記第２の切断刃３ａにより切断した後は、搬送コンベアＣ２は静止のまま、静止状態の細帯状豆腐生地Ｔ２１を第２の切断刃３ａで（ないしは下流側位置決め手段２ａとともに軽く挟持した状態で）下流方向に押して送るとともに、上流側位置決め手段６ａも下流方向に横移動して細帯状豆腐生地Ｔ２２に接し、次に搬送コンベアＣ２を駆動させて、その駆動に同期・同調するように第２の切断刃３ａ（ないしは第２の切断刃３ａと下流側位置決め手段２ａ）と上流側位置決め手段６ａを更に下流方向に横移動させて間隔を開いて整列した細帯状豆腐生地Ｔ２１、Ｔ２２を次工程Ｐ２へ移載する（図１４（７））。その移載の際に、次工程のＰ２がコンベアである場合はそのコンベアも同期・同調して駆動させることが好ましい。その後は位置決め手段、切断刃ともに上昇して上記の繰り返し動作の準備のため待機する（図１４（７）〜（８））。ここでの位置決め手段２ａ，６ａの太帯状豆腐生地Ｔ１から離れる時間差は僅かであり、離れると直ぐに第２の切断刃３ａが切断するので、位置決めは確保された状態で切断されている。本発明では、上記第２の切断刃３ａにより切断した後、上流側および下流側の位置決め手段６ａ、２ａが離れているため、搬送コンベアＣ２は静止のまま、第２の切断刃３ａを直ちに上流方向ないしは下流方向に移動させて、細帯状豆腐生地Ｔ２１とＴ２２の間隔を広げて整列させる。更に上流側および下流側の位置決め手段６ａ、２ａに接するまで広げるようにすることで正確に間隔を広げ整列することも可能である（図１４（７）〜(８)）。また本発明では位置決め手段の挟持による太帯状豆腐生地Ｔ１の歪み（特に挟持された豆腐生地が上方に盛り上がるか、位置決めのない行方向に伸びる現象）を除くとともに、切断前に位置決め状態の目視が可能になる。また離れた位置決め手段を上流方向ないしは下流方向に移動させて第２の切断刃を兼用するようにしてもよく、多少の時間は要するものの機器構成が簡素になり、衛生的かつ洗浄作業効率が上がる。
ここで、上記下流側と上流側の位置決め手段２ａ，６ａは、下降して位置決めした後に直ちに横移動するのではなく、すぐにその位置で上昇して太帯状豆腐生地から離れた後、第２の切断刃３ａで切断して、第２の切断刃３ａが細帯状豆腐生地Ｔ２１を下流方向に押し送る形態であってもよい（図１４（５ｂ）〜（８ｂ））。逆に第２の切断刃３ａが細帯状豆腐生地Ｔ２２を上流方向に押し戻す形態であってもよい。そして、位置決め手段２ａ，６ａが位置決めした後、上昇して位置決めを解除するものであり、これと入れ替わるようにして、これらの中央の切断刃３ａが降下して豆腐を切断する。第２の切断刃３ａが太帯状豆腐生地Ｔ１を切断すると、直ちに少し上昇して上流方向ないしは下流方向に動作して豆腐Ｔ２１とＴ２２との間隔を開ける。ここで搬送コンベアＣ２はその第２の切断刃３ａの動作に同期同調するように連動させて豆腐生地Ｔ２１、Ｔ２２の移動を補助するようにしてもよい。そして、第２の切断刃３ａが上昇すると、位置決め手段２ａ，６ａと同じように初期の待機状態に復帰する。本発明では上記下流側と上流側の位置決め手段２ａ，６ａや上記第２の切断刃３ａの列方向の動きを一部少なくでき、切断工程時間の短縮や動作機構の簡素化を図ることも可能である。
また第２の切断刃３ａで切断し間隔の開いた細帯状豆腐生地Ｔ２１、Ｔ２２を次工程Ｐ２に移載する際に、搬送コンベアＣ２を積極的に併用してもよい。すなわち、図１４（８ｂ）に図示したように、間隔の開いた細帯状豆腐生地Ｔ２１、Ｔ２２を搬送コンベアＣ２によって下流方向へ搬送して、次工程Ｐ２（特にコンベアタイプの工程）に移載する。その移載の際に、搬送コンベアＣ２と次工程Ｐ２のコンベア速度を同じにするよう同期・同調させる。あるいは次工程Ｐ２のコンベア速度を搬送コンベアＣ２よりも少し速めないしは遅めにして第２の切断工程で切断された細帯状豆腐生地Ｔ２１、Ｔ２２の間隔を微調整して整列させてもよい。この方法によれば生産中、豆腐生地の硬さ等により間隔が微妙に変化、変動するような場合に、機械的な取付を変更させることなく、細帯状豆腐生地Ｔ２１、Ｔ２２の間隔をコンベア駆動モータのインバータや電圧や無断減速機等の数値によって微調整可能である（特許4603056号参照）。
Seventh Embodiment
In the present embodiment, the thick band tofu dough T1 is cut out from the sheet-like tofu dough T on land without using the water tank W, and after the downstream and upstream positioning means 2a and 6a position the large band tofu dough T1. The second cutting blade 3a descends from the thick tofu dough T1 and cuts the plurality of rows of the thick tofu dough T1 into the thin tofu dough T21 and T22. In the present embodiment, prior to the second cutting, the tofu dough T1 is positioned by the positioning means on both the upstream side and the downstream side in the transport direction of the tofu dough T1 in advance (see FIGS. 13 and 14).
That is, when it is cut into two lines of tofu dough T1 by the first cutting blade 11a on the plate P1 on the upstream side of land, and is sent to the conveyer C2 by the first cutting blade 11a, it descends in advance. The downstream positioning means 2a brings the two rows of thick band-like tofu dough T1 to be conveyed stationary and positioned, and then the downstream positioning means 6a descends and then moves laterally to the downstream side for downstream positioning Positioning is performed so as to sandwich the means 2a (FIGS. 14 (1) to (4)). At this time, the tofu dough may be repeatedly held and released twice or more to correct the distortion of the shape of the soft tofu dough or the distortion of the internal stress.
After the thick tofu dough T1 is positioned on the upstream side and the downstream side, the downstream positioning means 2a moves downstream, and at the same time, the upstream positioning means 6a moves upstream and leaves the thick tofu dough T1. The second cutting blade 3a is lowered to cut the center of the thick tofu dough T1 (FIGS. 14 (5) to (6)). Here, the downstream positioning means 2a and the upstream positioning means 6a may move upward when they are separated from the thick tofu dough T1. The second cutting blade 3a causes the strip-like tofu dough T21 on the downstream side which has been cut and lifted slightly so as not to damage the belt of the conveyer C2 while sliding on the belt of the conveyer C2 at rest (or the conveyer A predetermined distance is pushed out toward the downstream side while the C2 is synchronously driven, and the C2 is spread and aligned at a predetermined interval with the upstream strip-like tofu dough T22. At that time, although the downstream positioning means 2a may ascend and retreat, it moves laterally in the upstream direction to lightly pinch the strip-like tofu dough T21 with the second cutting blade 3a, and then to the next process P2 thereafter. It may be synchronized and synchronized with the second cutting blade 3a at the time of transfer. After cutting by the second cutting blade 3a, the conveyor belt C2 is kept still, and the thin strip-like tofu dough T21 in the stationary state is lightly held by the second cutting blade 3a (or in a state of being lightly held together with the downstream positioning means 2a 2.) The downstream positioning means 6a is also moved laterally to contact the strip-shaped tofu dough T22 while pushing and feeding in the downstream direction, and then the transport conveyor C2 is driven to synchronize and synchronize with the drive Strip-shaped tofu dough T21, T22 aligned by further moving the cutting blade 3a (or the second cutting blade 3a and the downstream positioning means 2a) and the upstream positioning means 6a laterally further in the downstream direction Transfer to P2 (FIG. 14 (7)). In the case of the transfer, when P2 of the next process is a conveyor, it is preferable to drive the conveyor synchronously and synchronously. After that, both the positioning means and the cutting blade ascend and stand by in preparation for the above-mentioned repetitive operation (FIGS. 14 (7) to (8)). The time difference between the positioning means 2a, 6a and the thick tofu dough T1 is small, and as soon as the positioning means 2a, 6a separates, the second cutting blade 3a cuts, so that the positioning is cut in a secured state. In the present invention, since the upstream and downstream positioning means 6a and 2a are separated after being cut by the second cutting blade 3a, the conveyer C2 remains stationary, and the second cutting blade 3a is immediately upstream. It is moved in the direction or the downstream direction to widen and align the strips of tofu dough T21 and T22. Furthermore, it is also possible to accurately widen and align the space by extending the position until it contacts the upstream and downstream positioning means 6a, 2a (FIGS. 14 (7) to (8)). Further, in the present invention, distortion of the thick tofu dough T1 (in particular, the phenomenon in which the tofu dough held in the upper part swells upward or does not extend in the row direction) due to the pinching of the positioning means is eliminated. It will be possible. Alternatively, the separated positioning means may be moved in the upstream direction or the downstream direction to double as the second cutting blade, but the equipment configuration becomes simple although it takes some time, and hygienic and cleaning work efficiency is improved. .
Here, the positioning means 2a, 6a on the downstream side and the upstream side do not move laterally immediately after being positioned down, but immediately after rising at that position and leaving the thick tofu dough, the second The second cutting blade 3a may cut the thin tofu dough T21 in the downstream direction by cutting with the cutting blade 3a (FIGS. 14 (5b) to (8b)). Conversely, the second cutting blade 3a may push back the strip-shaped tofu dough T22 in the upstream direction. Then, after the positioning means 2a, 6a are positioned, they are lifted to release the positioning, and in place of this, the central cutting blade 3a is lowered to cut the tofu. When the second cutting blade 3a cuts the thick band-like tofu dough T1, it immediately ascends slightly and operates in the upstream direction or the downstream direction to open the space between the tofu T21 and T22. Here, the conveyer C2 may be interlocked in synchronization with the operation of the second cutting blade 3a to assist the movement of the tofu dough T21, T22. Then, when the second cutting blade 3a ascends, it returns to the initial standby state in the same manner as the positioning means 2a, 6a. In the present invention, the movement of the downstream and upstream positioning means 2a, 6a and the second cutting blade 3a in the row direction can be partially reduced, and the cutting process time can be shortened and the operating mechanism can be simplified. It is.
Further, when transferring the thin tofu dough T21, T22 which is cut by the second cutting blade 3a and has an interval to the next process P2, the conveyer C2 may be positively used in combination. That is, as shown in FIG. 14 (8b), the narrow band-like tofu dough T21, T22 with a gap is conveyed in the downstream direction by the conveyer C2 and transferred to the next process P2 (especially the process of the conveyor type). . At the time of the transfer, the conveyor speeds of the conveyer C2 and the next process P2 are synchronized and synchronized to be the same. Alternatively, the conveyor speed of the next step P2 may be slightly faster or slower than the conveyer C2 to finely adjust and align the intervals of the strip-shaped tofu dough T21 and T22 cut in the second cutting step. According to this method, the interval between the strip-shaped tofu dough T21 and T22 is driven by the conveyor without changing the mechanical attachment when the spacing slightly changes or fluctuates due to the hardness of the tofu dough during production. Fine adjustment is possible according to the motor inverter, voltage, and the value of an unauthorized reduction gear etc. (refer to patent 4603056).

According to the present embodiment, two rows of thick band-like tofu dough T1 are cut from the sheet-like tofu dough T by the first cutting blade 11a on the plate on the upstream side on land, without using the water tank W. When the sheet is pushed to the conveyer C2 by the cutting blade 11a and sent, positioning is performed once so as to be held by the first cutting blade 11a and the positioning means 2a (FIG. 15, FIG. 16). Then, when the positioning means 2a and 11a are lifted and the positioning is released, the thick band tofu dough T1 is moved by the activation of the conveyer C2 and stopped at a predetermined position, and the second above the position The cutting blade 3a stands by, and the second cutting blade 3a descends to cut the thick band-like tofu dough T1 into two equal parts in the row direction to obtain thin band-like tofu dough T21, T22 (FIG. 1) to (4)). At this time, after using the second cutting blade 3a as the downstream positioning means, the second cutting blade 3a ascends and moves laterally in the upstream direction or the downstream direction, and as a cutting blade this time descends tofu dough You may cut the center of (not shown). In that case, the positioning means 2a can be omitted to make the structure simpler and hygienic. Then, after the second cutting blade 3a cuts, the second cutting blade 3a moves in the downstream direction (or in the upstream direction) to move the strip-shaped tofu dough T21 on the downstream side to the downstream direction T22 is pushed forward for a predetermined distance and fed, and the space between the upstream strip-shaped tofu dough T22 and the downstream strip-shaped tofu dough T21 is opened and aligned (FIG. 16 (5)).

(The ninth embodiment)
According to the present embodiment, two rows of thick band-like tofu dough T1 are cut from the sheet-like tofu dough T by the first cutting blade 11a on the plate on the upstream side on land, without using the water tank W. When the first cutting blade 11a serves as the upstream positioning means and is positioned by the cutting blade 11a of the first embodiment, the conveying conveyor C2 is driven to once move away from the thick tofu dough T1. The second cutting blade 3a cuts the center again (FIG. 17, FIG. 18 (1) to (5)). At this time, by positioning the first cutting blade 11a and then lifting and separating it, it is possible to reduce positional deviation of the strip-shaped tofu dough after cutting due to the adhesion between the tofu dough and the cutting blade. When the second cutting blade 3a cuts the thick tofu T1 in the same manner as described above, it stops for a while and feeds the thin tofu dough T21 by activating the conveyer C2, and then the second cutting blade 3a rises. The interval between the strip-like tofu dough T21 and T22 is carried out by backward feeding the upstream side tofu dough T22 or moving to the upstream or downstream side with the second cutting blade 3a lowered. It is opened and sent to the next process P2 by driving of the transport conveyor C2 (FIG. 17, FIG. 18 (6) to (7)). In the present embodiment, the cutting blade 2a and the first cutting blade 11a may be lowered simultaneously.

(FIG. 22 (6)). Therefore, it serves as a grid-like cutting blade. The pseudo grid blades arranged in a grid shape, the vertical cutting blades, and the cutting blades in the row direction may be sequentially operated at the same position by different operating mechanisms to cut into grid grids. The comb-shaped cutting blade K1 in the column direction and the comb-shaped cutting blade 31a in the row direction are slightly raised and synchronized simultaneously and moved downstream and / or upstream simultaneously to form a substantially thin strip in the row direction The distance between the front and back of the tofu dough T31 and T32 cut into units is increased, and the row direction is positioned. Here, with the comb blade-shaped cutting blade 31a in the row direction remaining stationary, the conveyer C2 is activated to convey T31 to the downstream side, and the intervals before and after the tofu dough T31, T32 are expanded, positioned and aligned It is also good. According to the present embodiment, after being cut, on the conveying conveyor C2 to be sent downstream, the spacing in the row direction is increased by one in a staggered distribution alignment method, and as a result, the left and right spaces are separated by one. It is preferable to open and position in the matrix direction (see FIGS. 17 to 19 in FIGS. 26 to 28 and Patent No. 5008102). Alternatively, the spacing may be made by a distribution method using the speed difference between two conveyors that transport and convey one row or one column of tofu dough T3 in the row direction or column direction (patent 4603056)).

(Twelfth embodiment)
The present embodiment is an example in which the first cutting step is performed in water (in the water tank) W, and the reversing operation is performed to send out to the second cutting step. 32 (32F) is used in combination with the positioning means 2a on the downstream side to position and sandwich the thick tofu dough T1 (FIGS. 23, 24 and 25).
The large band of tofu dough T1 which has been cut from the sheet-like tofu dough T in the first cross-cutting step and transported in the water tank W by the conveyor is cut into two lines and the reversing mechanism 20 performs reversing operation. Then, it is sent to the land transport conveyer C2 and sent out to the second cross cutting step. In the upstream positioning means of the present embodiment, the pushing plate 32 of the pushing mechanism 30 for extruding the inverted tofu dough functions exactly as positioning means so that the tofu dough T1 is held together with the downstream positioning means 2a. (Figure 25). The thick band-like tofu dough T1 cut into a plurality of lines (two lines) and inverted by the first cutting blade 11b is conveyed by the conveying conveyor C2, and similarly by the positioning means 2a of the second cross cutting step. It is placed in a stopped state and is simultaneously cut by the second cutting blade 3a. In addition, it is also possible to cut | disconnect by the cutting blade 3a of a 2nd cross cutting process in the state aligned with either the pushing plate 32 (32F) which served as a positioning means or the positioning means 2a of the downstream. Then, in the same manner as described above, the interval between the strip-shaped tofu dough T21 and T22 is expanded in the lowered state as cut by the second horizontal cutting blade 3a, and the strip-shaped tofu dough T2 cut out into the downstream plate P2 is extruded. It also moves up and then climbs back to its original standby position.
第１の横切り切断工程の送り込み機構１０と後述する押し出し機構３０は、ケージ反転機構２０とは別にケージ反転機構２０の基台（空中に位置する基台）から支持されている。
押し出し機構３０は、水平フレーム３２Ｂに下垂姿勢の多数の下垂板である位置決め手段３２Ｆを並設した押し出し板３２を水平列方向と上下方向とに駆動する（図２３、図２４）。各下垂板３２Ｆは、それぞれ先端部に角板状の押当面３Ｆを形成した柄付きのへら状体（逆Ｔ字型）であり、多数の下垂板群３２Ｆは、定間隔を保って水平フレーム３２Ｂに取り付けられている。多数の下垂板群３２Ｆの押当面３Ｆは、同一平面に属するように整列されている。多数の下垂板群３２Ｆは、ケージ２Ｋからの排出側へ豆腐生地を押し出す際には、ケージ奥板２８の先端Ｅよりも下方になるように設定されている。このとき、ケージ奥板２８の下方先端Ｅよりも下方になるようにして太帯状豆腐生地Ｔ１がケージ下板（受け入れ姿勢時のケージ上板）２６上に載置された状態になる。
押し出し機構３０の押し出し板３２は、１基又は複数基の上下動シリンダＣ８および任意方式の上下動ガイド、例えば、ガイドロッドＬ８とガイドスリーブＧ８とからなる上下動ガイドを介して中間プレート３３に取り付けられ、また、中間プレート３３は、１基又は複数基の水平動シリンダＣ７および任意方式の水平動ガイド、例えば、ガイドロッドＬ７（図示なし）とガイドスリーブＧ７（図示なし）とからなる水平動ガイドを介して固定プレート３５，３５に取り付けられている。この結果、押し出し板３２は、上下動シリンダＣ８と水平動シリンダＣ７とによって上下方向及び水平列方向に移動することができる。
なお、水中ないしは半水中で本実施の形態を適用することも可能である。また、陸上にある前記太帯状豆腐生地Ｔ１を、陸上にある前記切断工程に送り出す送り出し機構３０を備え、この送り出し機構３０が前記切断工程における前記太帯状豆腐生地の上流端を位置決めする位置決め手段を兼用するものでも良い。
The feed mechanism 10 in the first cross cutting step and the push-out mechanism 30 described later are supported from the base (base located in the air) of the cage inversion mechanism 20 separately from the cage inversion mechanism 20.
The push-out mechanism 30 drives the push-out plate 32 in which the positioning means 32F, which is a large number of drop plates in the hanging posture, are juxtaposed to the horizontal frame 32B in the horizontal row direction and the vertical direction (FIG. 23, FIG. 24). Each pit plate 32F is a handle-like spatula (inverted T-shaped) in which a squat-shaped pressing face 3F is formed at the tip end, and the large number of pit plate groups 32F are horizontal frames keeping a fixed interval. It is attached to 32B. The pressing faces 3F of the large number of pital plate groups 32F are aligned so as to belong to the same plane. The many pitted plate groups 32F are set to be lower than the tip E of the cage back plate 28 when the tofu dough is pushed out to the discharge side from the cage 2K. At this time, the thick tofu dough T1 is placed on the cage lower plate (cage upper plate in the receiving posture) 26 so as to be lower than the lower end E of the cage back plate 28.
The push-out plate 32 of the push-out mechanism 30 is attached to the intermediate plate 33 via a vertical movement guide consisting of one or more vertical movement cylinders C8 and an arbitrary vertical movement guide, for example, a guide rod L8 and a guide sleeve G8. Also, the intermediate plate 33 is a horizontal movement guide consisting of one or more horizontal movement cylinders C7 and an optional horizontal movement guide, for example, a guide rod L7 (not shown) and a guide sleeve G7 (not shown) Are attached to the fixed plates 35, 35 via As a result, the pushing plate 32 can be moved in the vertical direction and in the horizontal row direction by the vertical movement cylinder C8 and the horizontal movement cylinder C7.

（第１３の実施の形態）
本実施の形態は、搬送コンベアＣ２による移動を制止する千鳥配列手段（位置決め手段）２１を備えて、交互に前後に開く、いわゆる千鳥形に間隔が広げられるようにする（図２６、図２７、図２８）。この千鳥形は特に後工程が包装工程でなく、フライヤーやフリーザーなどの工程の場合に適用しやすい。
上記搬送コンベアＣ２には、並走した状態で移送されてきた横１行分の各細帯状豆腐生地Ｔ２を、行方向に一つおきにせき止めて１個単位で隣接する１個分の豆腐生地Ｔ３を交互に搬送方向に進めて、間隔を開いて上方からみて千鳥配列に整列する千鳥配列手段（位置決め手段）２１が設けられている（図２７）。この千鳥配列手段２１は、搬送コンベアＣ２の下流に設置されるパック詰め手段６の前に、少なくとも１つは配されもので、各１個分の豆腐生地Ｔ３の進行方向に直交する回転軸Ｌ３に回転自在に取り付けられる千鳥配列板２１ａを有する。この千鳥配列板（位置決め手段）２１ａは、各豆腐生地Ｔの左右の幅に合わせた櫛歯有する櫛歯構造となっており、一つおきの豆腐生地（パック詰めする１丁分）を通過させ、一つおきの豆腐生地を停止状態におく。なお、この千鳥配列板２１ａの上端部は、伸縮自在の（駆動シリンダの）ロッド１１ｂに回転自在ないしは上下自在に連結されている。
(The 13th embodiment)
The present embodiment is provided with a zigzag arrangement means (positioning means) 21 for stopping the movement by the conveyer C2 so that the intervals can be expanded in a so-called zigzag shape alternately opened and closed (FIGS. 26, 27, Figure 28). This zigzag shape is particularly easy to apply in the case of a process such as a fryer or freezer, not a post-process is a packaging process.
In the above-mentioned conveyer C2, the thin band-like tofu dough T2 for one horizontal row transferred in parallel running state is clamped every other one in the row direction, and one tofu dough is adjacent by one unit A staggered arrangement means (positioning means) 21 is provided which advances T3 alternately in the transport direction, and opens the gap to align in a staggered arrangement as viewed from above (FIG. 27). At least one of the zigzag arranging means 21 is disposed in front of the packing means 6 disposed downstream of the conveyer C2, and the rotational axis L3 is orthogonal to the traveling direction of the tofu dough T3 for one unit. And a staggered array plate 21a rotatably mounted on the This staggered array plate (positioning means) 21a has a comb-tooth structure having comb teeth adjusted to the left and right width of each tofu dough T, and allows every other tofu dough (one pack to be packed) to pass through. Put every other tofu dough in a stopped state. The upper end portion of the staggered array plate 21a is rotatably or vertically coupled to a telescopic (drive cylinder) rod 11b.
搬送コンベアＣ２により並走した状態で横１行に並んだ各１個分の豆腐生地Ｔ３が通過しようとすると、まず、回転軸Ｌ３が下方に回動し、この回転軸Ｌ３に連結された千鳥配列板２１ａも下方に移動する。これにより、回転軸Ｌ３を中心に千鳥配列板２１ａが直立する方向に回転し、横１行分の各１個分の豆腐生地Ｔ３を一つおきにせき止める。千鳥配列板２１ａによって一部の１個分の豆腐生地Ｔ３はその位置でせき止められ、これに対し、せき止められなかった他の１個分の豆腐生地Ｔ３は進行する（図２８）。これにより、それまで横１列に並走した状態であった各豆腐生地Ｔが、千鳥配列となる。その後、千鳥配列板２１ａが上記とは逆に回転しせき止めていた残りの１個分の豆腐生地Ｔ３を進行させ、千鳥配列となった各１個分の豆腐生地Ｔ３（１丁）が、その配置を保ったままパック詰め手段（図示なし）に移送されることとなる。 When one unit of tofu dough T3 arranged in a row is attempted to pass parallel to one another by the conveyer C2, the rotation axis L3 is first rotated downward, and the zigzag connected to the rotation axis L3 The array plate 21a also moves downward. As a result, the zigzag array plate 21a rotates in the vertical direction about the rotation axis L3, and clamps one tofu dough T3 for every one horizontal row. A portion of the tofu dough T3 is stopped at that position by the staggered array plate 21a, while the other one portion of tofu dough T3 proceeds (FIG. 28). As a result, each tofu dough T, which has been in a state of parallel running in one horizontal row, becomes a staggered arrangement. After that, the zigzag alignment plate 21a is rotated in the reverse direction to the above to advance the remaining one serving of tofu dough T3 and the one serving of tofu dough T3 (one serving), which is in the staggered arrangement, It will be transported to the packing means (not shown) while maintaining the arrangement.
上記千鳥配列手段２１により、横１行状に並走した状態で移送されてきた１個分の各豆腐生地Ｔ３を容易に千鳥配列とすることができるので、パック詰め手段６がパックＰを各１個分の豆腐生地Ｔ３に被せる際、パックＰの綴じ代分のスペースを確保できるため、パック詰めをスムーズに行うことができる（特開2007-6759号参照）。なお、上記千鳥配列手段に限らず、他の千鳥配列手段（例えば、特開Ｈ１１−300692号参照）であってもよい。 Since each piece of tofu dough T3 transferred in parallel in a row can be easily arranged in a zigzag arrangement by the above-mentioned zigzag arrangement means 21, the packing means 6 can pack 1 pack P each When covering per unit of tofu dough T3, the space for the binding margin of the pack P can be secured, so packing can be smoothly performed (see Japanese Patent Application Laid-Open No. 2007-6759). In addition, not only the said zigzag arrangement means but another zigzag arrangement means (for example, refer Unexamined-Japanese-Patent No. H11-300692) may be used.
ここで、搬送コンベアＣ２上では多少各豆腐生地Ｔをベルト上でずらすことになり、衛生的で平滑なベルト材質を採用し、また摩擦力を抑えるために、そこに例えば水道水や井戸水など飲用可能な清水を散水するか、６０℃以上９９℃以下の高温状態のお湯を散布するか、食品添加物規格の次亜塩素酸水（又は弱酸性電解水）または次亜塩素酸ナトリウムを、有効濃度０．１〜２００ｐｐｍに調製した水を散布するなど、衛生的な手段を併用すると効果的である。衛生的手段はこれらに限ったものではない。場合によっては、ベルト上に水面を保つような、薄い水槽Ｗ１を設けて、ベルトの一部を薄い水槽Ｗ１に浸すようにしてもよい（図示なし）。 Here, on the conveyer C2, each tofu dough T is slightly shifted on the belt, and a hygienic and smooth belt material is adopted, and in order to suppress the frictional force, drinking water such as tap water or well water is used there. Watering possible fresh water, sprinkling hot water in a high temperature condition of 60 ° C or more and 99 ° C or less, or hypochlorous acid water (or weakly acidic electrolyzed water) or sodium hypochlorite according to the food additive specification It is effective to use a hygienic means such as spraying water prepared to a concentration of 0.1 to 200 ppm. Sanitary measures are not limited to these. In some cases, a thin water tank W1 may be provided to keep the water surface on the belt, and a part of the belt may be dipped in the thin water tank W1 (not shown).
上記千鳥配列となって搬送される各１個分の豆腐生地Ｔ３は、パック詰め手段６によってパック詰めされる。このパック詰め手段６は、搬送コンベアＣ２上に設置され、搬送コンベアＣ２上を流れる各１個分の豆腐生地Ｔ３を撮像する撮像手段Ｙ（図示せず）と、パックＰを掴む吸着手段Ｚを有し、撮像手段Ｙにより撮像された各１個分の豆腐生地Ｔ３の位置や傾きに合わせ各１個分の豆腐生地Ｔ３のパック詰めを行う産業用ロボット６ａから構成される。例えば、千鳥配列となって搬送される各豆腐生地Ｔ３の個数がＮ個である場合、このパック詰め手段６により、各豆腐生地Ｔ３のＮ個のパック詰めを同時に行うことが可能となる（特開2007-6759号参照）。 The one unit of tofu dough T <b> 3 transported in the zigzag arrangement is packed by the packing means 6. The packing means 6 is installed on the conveyer C2 and picks up an imaging means Y (not shown) for imaging one tofu dough T3 flowing on the conveyer C2, and an adsorbing means Z for grasping the pack P. It has an industrial robot 6a that packs the tofu dough T3 for each one piece in accordance with the position and inclination of the one piece of tofu dough T3 captured by the imaging means Y. For example, when the number of pieces of tofu dough T3 transported in a staggered arrangement is N, it is possible to pack N pieces of each tofu dough T3 simultaneously by this packing means 6 (especially, Open 2007-6759)).
