Description

本発明は、２枚の皮の間に内材を挟み込んだどら焼きの皮を製造するどら焼き用皮製造装置並びにどら焼き製造装置及び方法に関する。   The present invention relates to a dorayaki skin manufacturing apparatus, a dorayaki manufacturing apparatus and a method for manufacturing a dorayaki skin in which an inner material is sandwiched between two skins.

どら焼きは、従来より和菓子として広く知られた商品の１つであり、「どら焼き」という商品名で多種多様なものが製造販売されている。一般的などら焼きは、小麦粉、卵、砂糖、膨張剤、水等を混ぜ合わせた生地を焼き板で円板状に焼成して２枚の皮を作成し、作成した皮の間に粒餡等の内材を挟み込んで製造する。   Dorayaki is one of the products that has been widely known as Japanese confectionery, and a wide variety of products are manufactured and sold under the trade name “Dorayaki”. In general, hirayaki is made by baking a dough mixed with flour, eggs, sugar, swelling agent, water, etc. into a disk shape on a baking sheet, and then creating two skins. It is manufactured by sandwiching inner materials such as.

このように製造されるどら焼きを、手作業によらずに自動的に製造する製造装置が提案されている。例えば、特許文献１では、生地を焼成板上に供給して薄く引き延ばす生地供給装置と、焼成板を加熱して生地の下面を焼き、生地を反転させてもう一方の面を焼成板で加熱して焼く加熱処理装置と、焼いた生地上に中味を充填して別の焼いた生地を重ね合わせ、２つの生地の耳締めを行うどら焼き処理装置とを備えた製造装置が記載されている。   There has been proposed a manufacturing apparatus that automatically manufactures the dorayaki manufactured in this way without using manual work. For example, in Patent Document 1, a dough supply device that supplies a dough onto a fired plate and thins the dough, and heats the fired plate to bake the lower surface of the dough, inverts the dough and heats the other surface with the fired plate. There is described a manufacturing apparatus including a heat-treatment device for baking and a dorayaki processing device for superimposing another baked dough by filling the baked dough with another content and fastening the ears of the two doughs.

特開２００９−１００６８４号公報JP 2009-100654 A

上述した特許文献では、どら焼きの製造を自動化して量産化を図るようにしているが、どら焼きの２枚の皮の周縁部を密着させる耳締めの処理を安定して行うことが難しい。すなわち、耳締めの処理を行うためには、耳締め処理で付着させるための皮の周縁部に焼き目を付けないように生地を焼く必要がある。しかしながら、生地の周縁部に焼き目を付けない状態では生地が生焼け状態となって垂れるおそれがあるため、生地の周縁部についてもある程度加熱して生地が垂れない程度に硬化した状態としなければならない。   In the above-mentioned patent documents, the production of dorayaki is automated to achieve mass production, but it is difficult to stably perform the ear fastening process for bringing the two skins of dorayaki into close contact with each other. That is, in order to perform the ear fastening process, it is necessary to bake the dough so that the peripheral edge portion of the skin to be attached by the ear fastening process is not burnt. However, since there is a risk that the dough is drowned and drooped in a state where the peripheral edge of the dough is not baked, the peripheral edge of the dough must also be heated to some extent and hardened to the extent that the dough does not drip .

こうした状態は生地の周縁部に対して加熱処理を微調整する必要があるが、特許文献のように、生地の下面を焼いた後に反転してもう一方の面を焼成板で焼く処理では、加熱処理を微調整することは難しく、生地の周縁部が耳締めの処理に最適な状態となるように安定して加熱処理することは困難である。また、生地を反転してもう一方の面を焼く際に既に加熱により発泡して膨張する生地が反転により内部の気泡が抜けてしぼむように薄くなるため、ふっくらとした皮に安定して仕上げることができない欠点がある。   In such a state, it is necessary to finely adjust the heat treatment on the peripheral edge of the dough, but as in the patent document, in the treatment where the lower surface of the dough is reversed and the other surface is baked with the baking plate, It is difficult to finely adjust the treatment, and it is difficult to stably heat-treat the peripheral edge of the fabric so as to be in an optimum state for the ear-tightening treatment. Also, when the dough is turned over and the other side is baked, the dough that already foams and expands by heating is thinned so that the bubbles inside it are pulled out and squeezed out, so that the skin can be finished stably. There is a drawback that can not be.

そこで、本発明は、どら焼きの製造に好適な皮を作成することができるどら焼き用皮製造装置並びにどら焼き製造装置及び方法を提供することを目的とする。   Accordingly, an object of the present invention is to provide a dorayaki skin manufacturing apparatus, a dorayaki manufacturing apparatus and a method capable of producing a skin suitable for manufacturing dorayaki.

以下、本発明に係る実施形態について詳しく説明する。なお、以下に説明する実施形態は、本発明を実施するにあたって好ましい具体例であるから、技術的に種々の限定がなされているが、本発明は、以下の説明において特に発明を限定する旨明記されていない限り、これらの形態に限定されるものではない。   Hereinafter, embodiments according to the present invention will be described in detail. The embodiments described below are preferable specific examples for carrying out the present invention, and thus various technical limitations are made. However, the present invention clearly indicates that the invention is particularly limited in the following description. Unless otherwise specified, the present invention is not limited to these forms.

図１は、本発明に係る実施形態に関する概略正面図（図１（ａ））及びどら焼きの製造過程を示す説明図（図１（ｂ））である。どら焼き製造装置１は、どら焼きの皮の材料である生地を焼成板の上面に供給する生地供給部２、焼成板の上面に供給された生地を加熱して皮を焼成する生地焼成部３、焼成した皮を反転する皮反転部４、反転された皮に内材を供給して一対の皮で挟むように重ね合わせてどら焼きを成形する内材供給部５及び耳締め処理部６を備えている。   FIG. 1: is a schematic front view (FIG. 1 (a)) regarding embodiment which concerns on this invention, and explanatory drawing (FIG.1 (b)) which shows the manufacturing process of dorayaki. The dorayaki manufacturing apparatus 1 includes a dough supply unit 2 that supplies dough, which is a material of dorayaki skin, to the upper surface of the baking plate, and a dough baking unit 3 that heats the dough supplied to the upper surface of the baking plate and burns the skin. The skin reversing unit 4 for reversing the fired skin, the inner material supplying unit 5 for forming the dorayaki by superposing the inner material so as to be sandwiched between the pair of skins and the ear fastening processing unit 6 I have.

生地供給部２は、予め小麦粉、卵、砂糖、膨張剤、水等を混合して調製した生地を投入するホッパ１０及び生地を適量ずつ焼成板１２の上面に吐出するノズル１１を備えており、ノズル１１から吐出された生地は焼成板１２上に薄く延ばして円形状に形成される。   The dough supply unit 2 includes a hopper 10 for feeding dough prepared in advance by mixing flour, eggs, sugar, a swelling agent, water, and the like, and a nozzle 11 for discharging the dough to the upper surface of the baking plate 12 by an appropriate amount. The dough discharged from the nozzle 11 is thinly extended on the baking plate 12 and formed into a circular shape.

生地焼成部３は、無端状のチェーンベルトに短冊状の焼成板１２を複数枚配列した加熱コンベヤ１３を備えており、焼成板１２は、無端状のチェーンベルトを張架したプーリ１４を駆動することで、搬送されるようになっている。周状に配列された焼成板１２の内側には、下側加熱手段であるガスバーナー等の下側加熱装置１５が配置されており、上側に配列された焼成板１２は、下側加熱装置１５により下方から加熱されながら搬送されていく。また、上側に配置された焼成板１２の上方には、上側加熱手段である赤外線バーナー等の上側加熱装置１６及び１７が搬送方向に沿って配置されており、下流側の上側加熱装置１７と焼成板１２との間には、円形の貫通孔を形成した熱遮蔽板１８が配設されている。熱遮蔽板１８は、耐熱材料から構成され、上側加熱装置１７から放射される赤外線等が円形の貫通孔以外を通過しないように遮蔽し、円形の貫通孔から生地の上面に赤外線等を照射して生地の中心部分を円形に焼き色を付ける。   The dough baking unit 3 includes a heating conveyor 13 in which a plurality of strip-shaped baking plates 12 are arranged on an endless chain belt, and the baking plate 12 drives a pulley 14 that stretches an endless chain belt. Therefore, it is designed to be transported. A lower heating device 15 such as a gas burner which is a lower heating means is arranged inside the circumferentially arranged firing plates 12, and the upper firing device 12 is arranged on the lower heating device 15. Is conveyed while being heated from below. Further, above the baking plate 12 arranged on the upper side, upper heating devices 16 and 17 such as an infrared burner serving as an upper heating means are arranged along the conveying direction, and the upper heating device 17 and the baking on the downstream side are fired. A heat shielding plate 18 having a circular through hole is disposed between the plate 12 and the plate 12. The heat shielding plate 18 is made of a heat-resistant material, shields infrared rays or the like emitted from the upper heating device 17 from passing through other than the circular through holes, and irradiates infrared rays or the like on the upper surface of the fabric from the circular through holes. Bake the center of the dough in a circle.

図２は、生地焼成部３における生地の焼成過程を示す説明図である。生地Ｆは、生地供給部２から吐出されて焼成板１２の上面に載置されると、下側加熱装置１５により加熱された焼成板１２の熱により生地Ｆの下面が焼かれていく。加熱コンベヤ１３は、生地Ｆの焼成速度に対応させた搬送速度で焼成板１２を間欠搬送していき、焼成板１２の搬送中に生地Ｆの下面に対して適度な焼き色が付けられていく（図２（ａ））。   FIG. 2 is an explanatory diagram showing the baking process of the dough in the dough baking unit 3. When the dough F is discharged from the dough supply unit 2 and placed on the upper surface of the baking plate 12, the lower surface of the dough F is baked by the heat of the baking plate 12 heated by the lower heating device 15. The heating conveyor 13 intermittently conveys the baking plate 12 at a conveyance speed corresponding to the baking speed of the dough F, and an appropriate baking color is applied to the lower surface of the dough F during the conveyance of the baking plate 12. (FIG. 2 (a)).

そして、焼成板１２が間欠搬送されて上側加熱装置１６の下方において生地Ｆが対向配置された状態で一時停止するように搬送制御される。上側加熱装置１６に対向配置された状態で生地Ｆの上面側が加熱されるようになる。上側加熱装置１６では、生地Ｆの上面全体が加熱されて膨張し、生地Ｆの表面が流動しないように固まる程度に加熱処理される（図２（ｂ））。生地Ｆは、上側加熱装置１６を通過して間欠搬送されながら下側加熱装置１５により継続して下面側が焼かれていく（図２（ｃ））。   Then, the firing plate 12 is intermittently conveyed, and the conveyance control is performed so that the dough F is temporarily stopped in a state of being opposed to the lower side of the upper heating device 16. The upper surface side of the dough F is heated in a state of being disposed opposite to the upper heating device 16. In the upper heating device 16, the entire upper surface of the dough F is heated and expanded, and heat treatment is performed to such an extent that the surface of the dough F is hardened so as not to flow (FIG. 2B). The dough F is baked on the lower surface side by the lower heating device 15 while being intermittently conveyed through the upper heating device 16 (FIG. 2C).

次に、焼成板１２が間欠搬送されて上側加熱装置１７の下方において生地Ｆが対向配置された状態で一時停止するように搬送制御される。上側加熱装置１７に対向配置された状態では、上方から見て生地Ｆの中心部分が熱遮蔽板１８の貫通孔にほぼ一致するように設定され、貫通孔を通過した赤外線により生地Ｆの上側の中心部分が加熱されるようになる。上側加熱装置１７では、生地Ｆの中心部分が加熱により膨張して盛り上がるとともに表面が焼かれて円形の焼き色Ｂが付く程度に加熱処理される（図２（ｄ））。生地Ｆは、上側加熱装置１７を通過して間欠搬送されながら下側加熱装置１５により継続して下面側が焼かれていき、下面側全面に均等な焼き色が付いた状態となる（図２（ｅ））。   Next, conveyance control is performed so that the baking plate 12 is intermittently conveyed and the dough F is temporarily opposed to the lower side of the upper heating device 17 in a state of being opposed. In a state of being opposed to the upper heating device 17, the center portion of the fabric F is set so as to substantially coincide with the through hole of the heat shielding plate 18 when viewed from above, and the upper side of the fabric F is irradiated by infrared rays passing through the through hole. The central part is heated. In the upper heating device 17, the center portion of the dough F is heated and expanded to the extent that the surface is baked and a circular baked color B is attached (FIG. 2D). The dough F continues to be baked on the lower surface side by the lower heating device 15 while being intermittently conveyed through the upper heating device 17, and the entire lower surface side is colored (see FIG. 2). e)).

以上のように生地の焼成処理を行うことで、一方の面側に全面焼き色が付くとともに他方の面側に中心部分にのみ焼き色の付いた皮Ｋが焼成される。そして、皮Ｋの他方の面側の焼き色の付いていない周縁部は、生地が加熱により固まって流動せずわずかに焼き色が付いた状態となり、後述する耳締め処理の際に密着可能な程度の焼き加減に仕上げられている。また、生地Ｆの上面側を上側加熱装置１６及び１７により２度焼きすることで、生地Ｆの中央部分が膨張して盛り上がった形状の皮に仕上げることができ、後述するように製品として成形する場合に、ソフト感及びボリューム感を有する製品形状となる。   By performing the baking process of the dough as described above, the entire surface is colored on one side and the skin K colored only on the central part on the other side is baked. Further, the peripheral edge portion of the other surface side of the skin K which is not colored is in a state where the dough does not flow due to heating and does not flow, and is slightly colored. Finished to a moderate degree. Moreover, the upper surface side of the dough F is baked twice by the upper heating devices 16 and 17, so that the center portion of the dough F can be finished into a swelled shape and formed as a product as described later. In some cases, the product shape has a soft feeling and a volume feeling.

下側加熱装置１５は、生地の供給から生地の上側の加熱処理までの間の間欠搬送期間中に生地の下面側を加熱するようになっており、この期間中に生地に適度な焼き色が付く程度に焼成板１２の加熱温度を調整するように加熱制御される。   The lower heating device 15 is configured to heat the lower surface side of the dough during the intermittent conveyance period from the supply of the dough to the upper heat treatment of the dough. Heating control is performed so as to adjust the heating temperature of the fired plate 12 to such an extent that it adheres.

なお、上側加熱装置１６及び１７は、１つの加熱装置を用いてもよく、また赤外線を放射する加熱装置等を用いて熱源自体を円形にすることで熱遮蔽板１８を不要とすることもできる。   The upper heating devices 16 and 17 may use one heating device, or the heat shielding plate 18 may be unnecessary by making the heat source itself circular by using a heating device or the like that emits infrared rays. .

皮反転部４は、生地焼成部３に対して加熱コンベヤ１３の搬送方向下流側に配置されており、第一反転部２０及び第二反転部２１を備えている。第一反転部２０は、生地焼成部３のそれぞれの焼成板１２において焼成された一対の皮を把持して反転させながら搬送コンベヤ２２の搬送面に移送するように動作する。第二反転部２１は、第一反転部２０に対して搬送コンベヤ２２の搬送方向下流側に配置されており、第一反転部２０により反転した一対の皮のうち１枚を回動板で受けてもう一度反転させるように動作する。   The skin reversing unit 4 is disposed on the downstream side in the transport direction of the heating conveyor 13 with respect to the dough baking unit 3 and includes a first reversing unit 20 and a second reversing unit 21.

It is designed to rotate in the direction.

押え部材２０１は、回転シリンダ２０７の回転駆動により支持部材２００に対して回動動作を行うことができ、図３に示すように、支持部材２００から離間した待機位置及び支持部材２００に近接した作動位置に設定することが可能であり、押え部材２０１が作動位置に設定された状態では支持部材２００に重ね合うように配置される。そして、各押え部材２０１の一対の長辺部には、支持部材２００に対向する側にストッパ２０１ａが突設されており、押え部材２０１が作動位置に設定されると、ストッパ２０１ａが支持部材２００に近接配置されるようになっている。   The holding member 201 can rotate with respect to the support member 200 by the rotational drive of the rotary cylinder 207, and as shown in FIG. 3, the holding position separated from the support member 200 and the operation close to the support member 200 are performed. It can be set to a position, and is arranged so as to overlap the support member 200 in a state where the pressing member 201 is set to the operating position. Then, a stopper 201a protrudes from the pair of long sides of each pressing member 201 on the side facing the support member 200. When the pressing member 201 is set to the operating position, the stopper 201a is supported by the support member 200. Are arranged close to each other.

図５は、第一反転部２０の駆動機構に関する右側面図（図５（ａ））、背面図（図５（ｂ））及び上面図（図５（ｃ））である。駆動機構は、支持部材２００及び押え部材２０１を加熱コンベヤ１３の搬送方向に往復動させる移動機構、支持部材２００及び押え部材２０１を回動させる反転機構及び支持部材２００に対して押え部材２０１を回動させる作動機構を備えている。移動機構は、機枠１００の外側面に固定された一対のガイドレール１０１に取り付けられた板状のキャリッジ１０３を備えている。一対のガイドレール１０１は、上下に所定の間隔を空けて固定されており、キャリッジ１０３は、内側面に設けられた２対の係合部１０２がそれぞれガイドレール１０１に対して左右方向に移動可能に係合して支持されるようになっている。キャリッジ１０３の側方には、機枠１００に駆動モータ１０４が取り付けられており、駆動モータ１０４には、クランク機構１０５が設けられている。クランク機構１０５は、駆動モータ１０４の駆動軸に円板が固定されて円板の偏心した位置に作動シャフト１０６の一端が取り付けられており、駆動モータ１０４の回転動作を作動シャフト１０６の左右方向の往復動作に変換するようになっている。そして、作動シャフト１０６の他端がキャリッジ１０３の側端に固定されており、作動シャフト１０６が左右方向に往復動作することでキャリッジ１０３が左右方向に往復動するようになっている。この例では、駆動モータを用いてキャリッジ１０３を往復動させるようにしているが、エアシリンダ等の駆動手段を用いて往復動させるようにすることもできる。   FIG. 5 is a right side view (FIG. 5A), a rear view (FIG. 5B), and a top view (FIG. 5C) regarding the drive mechanism of the first reversing unit 20. The driving mechanism includes a moving mechanism that reciprocates the support member 200 and the presser member 201 in the conveying direction of the heating conveyor 13, a reversing mechanism that rotates the support member 200 and the presser member 201, and the support member 200 that rotates the presser member 201. An operating mechanism is provided. The moving mechanism includes a plate-like carriage 103 attached to a pair of guide rails 101 fixed to the outer surface of the machine casing 100. The pair of guide rails 101 are fixed vertically with a predetermined interval, and the carriage 103 is movable in the left-right direction with respect to the guide rail 101 by two pairs of engaging portions 102 provided on the inner surface. It is adapted to be engaged with and supported. A drive motor 104 is attached to the machine frame 100 on the side of the carriage 103, and the drive motor 104 is provided with a crank mechanism 105. In the crank mechanism 105, a disk is fixed to the drive shaft of the drive motor 104, and one end of the operation shaft 106 is attached to an eccentric position of the disk, and the rotation operation of the drive motor 104 is performed in the horizontal direction of the operation shaft 106. It converts to reciprocating motion. The other end of the operating shaft 106 is fixed to the side end of the carriage 103, and the carriage 103 reciprocates in the left-right direction when the operating shaft 106 reciprocates in the left-right direction. In this example, the carriage 103 is reciprocated using a drive motor, but it can also be reciprocated using drive means such as an air cylinder.

機枠１００には、移動位置検知センサ１１０が設けられており、駆動モータ１０４を駆動してキャリッジ１０３を左右方向に移動させ、キャリッジ１０３が所定位置に到来したことを移動位置検知センサ１１０が検知すると駆動モータ１０４を駆動停止し、キャリッジ１０３を所定位置に位置決めすることができる。   The machine frame 100 is provided with a movement position detection sensor 110. The movement position detection sensor 110 detects that the carriage 103 has arrived at a predetermined position by driving the drive motor 104 to move the carriage 103 in the left-right direction. Then, the drive motor 104 can be stopped and the carriage 103 can be positioned at a predetermined position.

反転機構は、支持部材２００及び押え部材２０１を回動させるために、キャリッジ１０３に取り付けられた駆動モータ１０７を備えており、駆動モータ１０７の駆動軸には駆動プーリ１０８が取り付けられている。そして、駆動プーリ１０８は、従動プーリ２０５との間に駆動ベルト１０９が張架されており、駆動プーリ１０８の回転駆動に連動して従動プーリ２０５が回動するようになっている。したがって、駆動モータ１０７を回転駆動することで、回転軸体２０６が回転して支持部材２００及び押え部材２０１を加熱コンベヤ１３の搬送方向に回動させるようになっている。   The reversing mechanism includes a drive motor 107 attached to the carriage 103 for rotating the support member 200 and the presser member 201, and a drive pulley 108 is attached to the drive shaft of the drive motor 107. A driving belt 109 is stretched between the driving pulley 108 and the driven pulley 205, and the driven pulley 205 rotates in conjunction with the rotational driving of the driving pulley 108. Therefore, when the drive motor 107 is driven to rotate, the rotary shaft 206 is rotated to rotate the support member 200 and the pressing member 201 in the conveying direction of the heating conveyor 13.

また、キャリッジ１０３には、取付部材を介して回転位置検知センサ１１１が設けられており、回転位置検知センサ１１１は、回転軸体２０６に連結された回転体１１２の回動を検知するように設定されている。そして、駆動モータ１０７を駆動して回転軸体２０６を回転させ、回転軸体２０６と同期して回動する回転体１１２が所定の回転角度位置まで回動したことを回転位置検知センサ１１１が検知すると、駆動モータ１０７を駆動停止する。そのため、回転軸体２０６に固定された支持部材２００を所定の回転角度位置に位置決めすることができる。   Further, the carriage 103 is provided with a rotational position detection sensor 111 via an attachment member, and the rotational position detection sensor 111 is set so as to detect the rotation of the rotary body 112 connected to the rotary shaft body 206. Has been. Then, the rotation position detection sensor 111 detects that the rotation shaft 112 is rotated to the predetermined rotation angle position by driving the drive motor 107 to rotate the rotation shaft body 206 and rotating in synchronization with the rotation shaft body 206. Then, the drive of the drive motor 107 is stopped. Therefore, the support member 200 fixed to the rotation shaft body 206 can be positioned at a predetermined rotation angle position.

作動機構は、上述したように、押え部材２０１を回動させる回転シリンダ２０７を備えている。押え部材２０１を固定した回転軸体２０８は、回転軸体２０６の両端部に取付固定された軸支部材２０８ａに両端部を挿入して回動可能に軸支されており、一方の端部が軸支部材２０８ａに固定された回転シリンダ２０７と連結している。回転シリンダ２０７は、ほぼ９０度の角度範囲を回転駆動するように設定されており、回転シリンダ２０７を適宜回転させることで、押え部材２０１を支持部材２００と近接する作動位置又は支持部材２００とほぼ直交する待機位置に設定することができる。   As described above, the operating mechanism includes the rotating cylinder 207 that rotates the pressing member 201. The rotary shaft body 208 to which the pressing member 201 is fixed is pivotally supported by inserting both end portions into pivot support members 208a attached and fixed to both end portions of the rotary shaft body 206, and one end portion is supported. The rotary cylinder 207 is fixed to the shaft support member 208a. The rotary cylinder 207 is set so as to rotate in an angle range of approximately 90 degrees. By appropriately rotating the rotary cylinder 207, the pressing member 201 is moved to an operating position close to the support member 200 or substantially the same as the support member 200. The standby position can be set to be orthogonal.

第二反転部２１では、回動板２０３を支持固定する回転軸体２０９が搬送コンベヤ２２の搬送方向に対して直交する方向に沿って配設されており、回転軸体２０９は回転シリンダ２１０に連結されて回転駆動されるようになっている。第一反転部２０により反転移送された２枚の皮のうち１枚の皮が回動板２０３上に載置された後回転シリンダ２１０を回転駆動して回動板２０３を搬送コンベヤ２２の搬送方向にほぼ１８０度回動させることで、回動板２０３上に載置された皮を反転させることができる。   In the second reversing unit 21, a rotary shaft body 209 that supports and fixes the rotating plate 203 is disposed along a direction orthogonal to the transport direction of the transport conveyor 22, and the rotary shaft body 209 is attached to the rotary cylinder 210. It is connected and rotationally driven. After one of the two peels reversed and transferred by the first reversing unit 20 is placed on the rotating plate 203, the rotating cylinder 210 is driven to rotate and the rotating plate 203 is conveyed by the conveyor 22 The skin placed on the rotating plate 203 can be reversed by rotating it approximately 180 degrees in the direction.

押止部材２０４は、細幅の板状体からなり、搬送コンベヤ２２の搬送方向に対して直交する方向に沿って配設されたシャフト２１１に直立するように取付固定されている。シャフト２１１の一端部は、駆動シリンダ２１３の駆動体２１２に固定されており、駆動シリンダ２１３が搬送コンベヤ２２の搬送方向に沿って駆動体２１２を往復動させることで、押止部材２０４が搬送コンベヤ２２の搬送面の上方において搬送方向に往復動作するようになっている。押止部材２０４は、後述するように、第一反転部２０により皮を反転し搬送コンベヤ２２に移送する工程において支持部材２００及び押え部材２０１を戻す際に皮に当接して押し止め、皮を搬送コンベヤ２２の搬送面に載置するように作用する。   The holding member 204 is made of a thin plate-like body, and is attached and fixed so as to stand upright on a shaft 211 disposed along a direction orthogonal to the transport direction of the transport conveyor 22. One end of the shaft 211 is fixed to the drive body 212 of the drive cylinder 213, and the drive cylinder 213 reciprocates the drive body 212 along the transport direction of the transport conveyor 22, so that the holding member 204 is moved to the transport conveyor. The reciprocating operation is performed in the transport direction above the transport surface 22. As will be described later, the retaining member 204 abuts against the skin when the support member 200 and the retaining member 201 are returned in the process of reversing the skin by the first reversing unit 20 and transferring it to the conveyor 22. It acts so as to be placed on the transport surface of the transport conveyor 22.

図６から図１２は、皮反転部４の動作に関する説明図である。図６（ａ）から図１２（ａ）は、皮反転部４に関する概略上面図を示しており、図６（ｂ）から図１２（ｂ）は、皮反転部４に関する概略正面図を示している。   6 to 12 are explanatory diagrams relating to the operation of the skin reversing unit 4. 6 (a) to 12 (a) show schematic top views of the skin reversal unit 4, and FIGS. 6 (b) to 12 (b) show schematic front views of the skin reversal unit 4. FIG. Yes.

図６では、焼成板１２に載置されながら加熱されて焼かれた皮Ｋが加熱コンベヤ１３により間欠搬送されてくる。支持部材２００は、焼成板１２の上面とほぼ平行となるように設定され、押え部材２０１は、支持部材２００に対して上方に向かってほぼ直角方向となる開いた状態に設定されている。図７では、回転軸体２０６を回転駆動して支持部材２００を下方にわずかに傾けながら皮Ｋに向かってキャリッジ１０３（図示せず）を移動するように動作する。皮Ｋが間欠搬送されるタイミングで支持部材２００を移動させることで、支持部材２００の先端が焼成板１２の上面を滑るように皮Ｋの底面に入り込み、支持部材２００が全体にわずかに撓んだ状態となって皮Ｋの底面を焼成板１２から剥がすように作用する。そのため、皮Ｋの底面が焼成板１２からきれいに剥離して支持部材２００の上面に掬い上げられた状態となる。図８では、回転軸体２０８が回転駆動され押え部材２０１が支持部材２００に接近する方向に回動して皮Ｋの上面に接触した作動位置に設定され、支持部材２００及び押え部材２０１により皮Ｋが挟持されるようになる。押え部材２０１は、コ字状に形成されているため、皮Ｋの上面に形成された焼き色が付いた中心部分の両側を押えるようになる。そのため、膨張した中心部分が押えられることがなく皮Ｋがふっくらした状態のまま挟持することができる。また、膨らんだ状態の中心部分を囲むように押え部材２０１が配置されるので、皮Ｋを安定した状態でしっかりと保持することが可能となる。押え部材２０１のストッパ２０１ａは、皮Ｋの外周縁に近接した位置に設定され、反転する際に皮Ｋが回転軸体２０６側にずれないようになっている。そのため、回転軸体２０６とストッパ２０１ａとの間には、支持部材２００及び押え部材２０１の内側の隙間が空いた状態となる。   In FIG. 6, the skin K heated and baked while being placed on the baking plate 12 is intermittently conveyed by the heating conveyor 13. The support member 200 is set so as to be substantially parallel to the upper surface of the fired plate 12, and the pressing member 201 is set in an open state that is substantially perpendicular to the support member 200 upward. In FIG. 7, the rotary shaft body 206 is driven to rotate, and the carriage 103 (not shown) is moved toward the leather K while the support member 200 is slightly tilted downward. By moving the support member 200 at the timing at which the skin K is intermittently conveyed, the front end of the support member 200 enters the bottom surface of the skin K so as to slide on the upper surface of the firing plate 12, and the support member 200 slightly bends as a whole. In this state, the bottom surface of the skin K is peeled from the fired plate 12. Therefore, the bottom surface of the skin K is cleanly peeled off from the fired plate 12 and is scooped up on the upper surface of the support member 200. In FIG. 8, the rotary shaft 208 is driven to rotate and the presser member 201 is rotated in a direction approaching the support member 200 and is set to an operating position in contact with the upper surface of the leather K. The support member 200 and the presser member 201 K comes to be pinched. Since the pressing member 201 is formed in a U shape, the pressing member 201 can press both sides of the center portion with a baked color formed on the upper surface of the leather K. Therefore, the inflated center portion is not pressed and can be sandwiched while the skin K is in a fluffy state. Further, since the pressing member 201 is disposed so as to surround the center portion in the swelled state, it is possible to hold the leather K firmly in a stable state. The stopper 201a of the pressing member 201 is set at a position close to the outer peripheral edge of the skin K so that the skin K does not shift toward the rotating shaft body 206 when it is reversed. Therefore, a gap is formed between the rotating shaft body 206 and the stopper 201a inside the support member 200 and the pressing member 201.

図９では、皮Ｋが支持部材２００及び押え部材２０１に挟持された状態で回転軸体２０６が回転駆動されて反転動作が行われるとともにキャリッジ１０３が搬送コンベヤ２２の方へ移動する。反転動作により押え部材２０１が皮Ｋの下側に配置され、支持部材２００が皮Ｋの上側に配置される。また、皮Ｋの上面側が全面焼き色が付いた面となり、皮Ｋの下面側が中心部分にのみ焼き色の付いた面となる。   In FIG. 9, the rotary shaft 206 is driven to rotate in a state where the leather K is sandwiched between the support member 200 and the pressing member 201, and the reversing operation is performed, and the carriage 103 moves toward the transport conveyor 22. The pressing member 201 is disposed on the lower side of the leather K and the support member 200 is disposed on the upper side of the leather K by the reversing operation. Further, the upper surface side of the skin K is a surface that is entirely baked, and the lower surface side of the skin K is a surface that is baked only at the central portion.

一方、押止部材２０４は、搬送コンベヤ２２の端部に配置されて上方に向かって直立した状態に設定され、回動板２０３は、搬送コンベヤ２２の搬送面上において押止部材２０４に隣接して配置されている。図１０では、キャリッジ１０３の移動動作により反転動作した支持部材２００及び押え部材２０１が搬送コンベヤ２２の搬送面の上方に配置されるようになり、その際に押止部材２０４は、回転軸体２０６とストッパ２０１ａとの間に形成された支持部材２００及び押え部材２０１の内側の隙間に挿入されるようになる。また、回動板２０３は、１枚の皮Ｋを保持する支持部材２００及び押え部材２０１の下方に対向配置されるようになる。   On the other hand, the holding member 204 is arranged at the end of the conveyor 22 and set in an upright state. The rotating plate 203 is adjacent to the holding member 204 on the transfer surface of the conveyor 22. Are arranged. In FIG. 10, the support member 200 and the presser member 201 that are reversed by the movement operation of the carriage 103 are arranged above the transport surface of the transport conveyor 22, and at this time, the presser member 204 is the rotating shaft body 206. And the stopper 201a, the support member 200 and the presser member 201 are inserted into a gap inside. Further, the rotating plate 203 is arranged to be opposed to the lower side of the supporting member 200 and the pressing member 201 that hold one piece of skin K.

次に、図１１では、キャリッジ１０３を加熱コンベヤ１３の方へ移動させる。キャリッジ１０３の移動に伴い支持部材２００及び押え部材２０１が加熱コンベヤ１３側に移動するようになるが、支持部材２００及び押え部材２０１に挟持された皮Ｋは、押止部材２０４に当接して押し止められるようになる。そのため、支持部材２００及び押え部材２０１の間から皮Ｋがすり抜けて、１枚の皮Ｋは搬送コンベヤ２２の搬送面に載置され、もう１枚の皮Ｋは回動板２０３の上面に載置されるようになる。   Next, in FIG. 11, the carriage 103 is moved toward the heating conveyor 13. As the carriage 103 moves, the support member 200 and the presser member 201 move toward the heating conveyor 13, but the leather K sandwiched between the support member 200 and the presser member 201 comes into contact with the presser member 204 and presses it. You can stop. Therefore, the skin K slips through between the support member 200 and the presser member 201, and one skin K is placed on the transport surface of the transport conveyor 22, and the other skin K is placed on the upper surface of the rotating plate 203. Will be placed.

図１２では、回転軸体２０６及び回転軸体２０８が回転駆動され、支持部材２００及び押え部材２０１が図６に示す回動位置と同じ位置となるように回動する。支持部材２００が焼成板１２に対向する位置に設定され、押え部材２０１が支持部材２００と直交する待機位置に設定される。押止部材２０４は、加熱コンベヤ１３側に移動して待機位置に設定される。そして、回転シリンダ２１０が回転駆動され、回動板２０３が搬送コンベヤ２２の搬送方向に回動して皮Ｋを再度反転動作させる。この反転動作により皮Ｋの上面側が中心部分のみ焼き色の付いた面となり、もう１枚の皮Ｋの上面側が全面焼き色の付いた面のままで２枚の皮Ｋが並列した状態で内材供給部５に搬送される。   In FIG. 12, the rotating shaft body 206 and the rotating shaft body 208 are rotationally driven, and the support member 200 and the pressing member 201 rotate so as to be in the same position as the rotation position shown in FIG. The support member 200 is set at a position facing the firing plate 12, and the presser member 201 is set at a standby position orthogonal to the support member 200. The holding member 204 moves to the heating conveyor 13 side and is set at the standby position. Then, the rotating cylinder 210 is driven to rotate, and the rotating plate 203 rotates in the conveying direction of the conveying conveyor 22 to reversely rotate the leather K again. By this reversal operation, the upper surface side of the skin K becomes a surface colored only in the center portion, and the upper surface side of the other skin K remains the entire surface colored with the inner surface in the state where the two skins K are arranged in parallel. It is conveyed to the material supply unit 5.

以上説明したように皮の反転動作を行うことで、生地焼成部３で中心部分が焼けたふっくらした状態に仕上げられた皮にダメージをほとんど与えることなく反転動作を行うことができる。すなわち、支持部材２００及び押え部材２０１により皮を挟み込んで回動するため皮がずれることがなく、安定した状態で反転することが可能となる。また、搬送コンベヤに載置する際に、支持部材２００及び押え部材２０１で皮を把持した状態で搬送コンベヤ上に停止した後支持部材２００及び押え部材２０１を引き抜くように移動させて皮を搬送コンベヤに載置するようにしているので、反転動作の際に皮が受けるダメージを最小限とすることができる。   As described above, by performing the reversal operation of the skin, the reversal operation can be performed with almost no damage to the skin finished in the fluffy state where the center portion is burnt in the dough baking unit 3. That is, since the support member 200 and the presser member 201 sandwich the skin and rotate, the skin does not shift and can be reversed in a stable state. In addition, when placing on the conveyor, the support member 200 and the holding member 201 are stopped on the conveyor while being held by the support member 200 and the holding member 201, and then the support member 200 and the holding member 201 are moved so as to be pulled out. Therefore, the damage to the skin during the reversing operation can be minimized.

図１（ａ）に示すように、内材供給部５は、皮反転部４に対して搬送コンベヤ２２の搬送方向下流側に配置されており、餡等の内材を投入するホッパ２３及び内材を適量ずつ皮の上に吐出するノズル２４を備えている。内材供給部５では、第二反転部２１により反転された皮の上面の焼き色が付いた中心部分に内材を配置するようにノズル２４から内材を吐出する。   As shown in FIG. 1 (a), the inner material supply unit 5 is arranged on the downstream side in the transport direction of the transport conveyor 22 with respect to the skin reversing unit 4, and includes a hopper 23 and an inner member for feeding the inner material such as a basket. A nozzle 24 is provided for discharging an appropriate amount of material onto the skin. In the inner material supply unit 5, the inner material is discharged from the nozzle 24 so as to dispose the inner material in the center portion of the upper surface of the skin inverted by the second reversing unit 21.

内材供給部５には、ノズル２４の上流側にガイド機構２５が設けられており、ガイド機構２５は、搬送コンベヤ２２により搬送されてくる２枚の皮に当接して整列させる。また、ノズル２４の下流側に移載機構２６が設けられており、移載機構２６は、皮Ｋの上面に吸引して持ち上げる吸引手段を備えている。そして、搬送コンベヤ２２により搬送されてくる２枚の皮のうち内材を載置していない方の皮を吸引手段により持ち上げて、もう一方の皮の上に重ね合わせ、内材を２枚の皮で挟むように配置する。この場合、２枚の皮の内側の面が中心部分にのみ焼き色の付いた面となっており、焼き色の付いていない周縁部分が対向配置した状態に設定されている。   The inner material supply unit 5 is provided with a guide mechanism 25 on the upstream side of the nozzle 24, and the guide mechanism 25 contacts and aligns the two skins conveyed by the conveyor 22. Further, a transfer mechanism 26 is provided on the downstream side of the nozzle 24, and the transfer mechanism 26 includes suction means for sucking and lifting the upper surface of the skin K. Then, of the two skins transported by the transport conveyor 22, the skin on which the inner material is not placed is lifted by the suction means and superimposed on the other skin, and the inner material is Arrange it so that it is sandwiched between skins. In this case, the inner surface of the two sheets is a surface colored only in the central portion, and the peripheral portions that are not colored are set to face each other.

耳締め処理部６は、移載機構２６に対して搬送コンベヤ２２の搬送方向下流側に配置されており、重ね合わされた２枚の皮を上下方向から挟むように型押しする上型３０及び下型３１を有する耳締め機構と、搬送コンベヤ２２から移送された２枚重ねの皮を紐状ベルトで搬送する搬送コンベヤ３２とを備えている。上型３０及び下型３１は、２枚重ねの皮の周縁部を上下方向から挟圧して閉じるように密着させて耳締め処理を行う。   The ear fastening processing unit 6 is disposed downstream of the transfer mechanism 26 in the transport direction of the transport conveyor 22, and an upper mold 30 and a lower mold that press the two stacked skins from above and below. An ear fastening mechanism having a mold 31 and a transport conveyor 32 for transporting the double-layered skin transferred from the transport conveyor 22 by a string-like belt are provided. The upper mold 30 and the lower mold 31 are subjected to an ear fastening process by closely contacting the peripheral portions of the two-layered skin from above and below so as to be closed.

どら焼きの製造工程では、図１（ｂ）に示すように、まず、加熱コンベヤ１３で搬送される焼成板１２の上面に、２枚の皮に対応して生地Ｆが吐出され円形状に形成される。焼成板１２が搬送されていく間に下側加熱装置１５により加熱されて生地Ｆの下面が焼かれていき、生地Ｆの上面についても上側加熱装置１６及び１７により加熱されて焼かれ、一方の面に全面焼き色が付き他方の面に中心部分のみ焼き色の付いた２枚の皮Ｋが焼成される。皮Ｋは、第一反転部２０により反転されて搬送コンベヤ２２に移送され、１枚の皮Ｋについてはさらに第二反転部２１により反転されて、１枚の皮Ｋは全面焼き色の付いた面が上面側となり、もう１枚の皮Ｋは中心部分のみ焼き色の付いた面が上面側となる。   In the dorayaki manufacturing process, as shown in FIG. 1B, first, the dough F is discharged on the upper surface of the baking plate 12 conveyed by the heating conveyor 13 to form a circular shape corresponding to the two peels. Is done. While the baking plate 12 is being conveyed, it is heated by the lower heating device 15 and the lower surface of the dough F is baked, and the upper surface of the dough F is also heated and baked by the upper heating devices 16 and 17. Two peels K having the entire surface baked in color and the other surface baked only in the center are baked. The leather K is reversed by the first reversing unit 20 and transferred to the conveyor 22, and the single leather K is further reversed by the second reversing unit 21, so that the single leather K is colored on the entire surface. The surface is the upper surface side, and the surface of the other skin K that is colored in the center is the upper surface side.

それぞれ反転された２枚の皮Ｋは、搬送コンベヤ２２により内材供給部５に搬送されていき、ガイド機構２５により２枚の皮Ｋの先端が揃えられる。次に、２枚の皮Ｋは内材供給部５のノズル２４の下方に搬送され、上面側が中心部分のみ焼き色の付いた皮Ｋに適量の内材Ｇが供給されて焼き色の付いた中心部分に配置される。次に、２枚の皮Ｋは移載機構２６の下方に搬送され、上面側が全面焼き色の付いた皮Ｋが持ち上げられて内材Ｇが配置された皮Ｋに重ね合わせ、内材Ｇを２枚の皮Ｋで挟むようにセットする。２枚の皮Ｋを重ね合わせた状態で耳締め処理部６の搬送コンベヤ３２に移送し、上型３０及び下型３１により２枚の皮Ｋの周縁部分を型押しする。こうして中心部分が膨らんでふっくらした状態に仕上げられた皮を用いて周縁部を密着させたソフト感及びボリューム感を有する成形品Ｈを製造することができる。   The two skins K that are reversed are transported to the inner material supply unit 5 by the transport conveyor 22, and the tips of the two skins K are aligned by the guide mechanism 25. Next, the two skins K are conveyed below the nozzle 24 of the inner material supply unit 5, and an appropriate amount of the inner material G is supplied to the leather K whose upper surface is colored only at the central portion, so that it becomes colored. Located in the central part. Next, the two skins K are transported below the transfer mechanism 26, and the upper surface side of the skin K, which is colored in full color, is lifted and superimposed on the skin K on which the inner material G is arranged. Set so that it is sandwiched between two skins K. In a state where the two skins K are overlapped, they are transferred to the transport conveyor 32 of the ear fastening processing unit 6, and the peripheral portions of the two skins K are pressed by the upper mold 30 and the lower mold 31. Thus, a molded product H having a soft feeling and a volume feeling in which the peripheral edge portion is in close contact with the skin finished in a state where the central portion is swollen and plump can be manufactured.

以上説明した例では、２列の生地Ｆを供給して皮Ｋを焼成して１つの成形品Ｈを製造するようにしているが、焼成板１２のサイズを大きくして４列以上の偶数列で生地Ｆを供給して一度に複数の成形品Ｈを製造するようにすることもできる。また、第一反転部では、加熱コンベヤの焼成板から皮を掬い上げて反転動作し、搬送コンベヤに移送するようにしているが、加熱コンベヤ上に第一反転部を配置して焼成板から焼成板へ反転動作するように設定することもできる。   In the example described above, two rows of fabrics F are supplied and the skin K is baked to produce one molded product H. However, the size of the baked plate 12 is increased to an even number of four or more rows. The dough F can be supplied to produce a plurality of molded articles H at a time. Moreover, in the 1st inversion part, it peels up from the baking board of a heating conveyor, reverse | inverts, and it is made to transfer to a conveyance conveyor, but arrange | positions a 1st inversion part on a heating conveyor and bakes from a baking board. It can also be set to reverse to the plate.

なお、上述した例では、生地供給部２、生地焼成部３及び皮反転部４からなるどら焼き用皮製造装置として構成することもできる。   In addition, in the example mentioned above, it can also be comprised as a dorayaki skin manufacturing apparatus which consists of the dough supply part 2, the dough baking part 3, and the skin inversion part 4. FIG.
