ところで，本出願人に係る上記おにぎり製造装置では，成型円盤を用いるものであって，均一な品質のおにぎりを大量に製造する装置としては, 非常に優れた装置であるが，おにぎりの成形工程では, 米飯を成型孔内の周囲の壁と成型孔内で作動する上下の成形ユニットにより, 米飯が型内で全く逃げ場のない状態にして圧縮し成形するので, 出来上がったおにぎりが, 手で握ったおにぎりに比較して硬く，ふっくら感に欠ける傾向があった。また，上記おにぎり製造装置は，米飯の具穴に具を入れた具入り米飯を，成型円盤上に形成した成型孔内で一度に圧縮成形しているので，出来上がったおにぎりが硬く食感が良いとは言えないものであった。 By the way, the above-mentioned rice ball manufacturing apparatus according to the present applicant uses a molding disk, and is an excellent apparatus for mass-producing rice balls of uniform quality. The cooked rice is compressed and molded by the surrounding wall in the molding hole and the upper and lower molding units that operate in the molding hole so that there is no escape in the mold. There was a tendency to be harder and less plump than rice balls. In addition, the above rice ball manufacturing apparatus compresses the cooked cooked rice with the cooked rice in the mold hole at once in the molding hole formed on the molded disk, so the resulting rice ball is hard and has a good texture. It could not be said.

また，最近では，おにぎりを食する消費者も含め, おにぎり製造業界の関係者の声として「手作り感のあるふっくらとしたおにぎり」の製造を機械ができないかという声が強まっているのが現状である。そこで，本出願人は，上記の課題を考慮して, 人が手でおにぎりを握るときの動作を改めて細かく分析してみて, 特に，米飯上に所定の具を載せた後に, 具を米飯で包み込むように，米飯を折り込む時の動きと，米飯を所定形状に成形しておにぎりを成形する時の成形型の動きについては, 出来るだけ人の手の動きに近づけることにより，手作り感のあるふっくらとしたおにぎりを製造することができるのではないかとの結論に至った。 In recent years, the voice of people involved in the rice ball manufacturing industry, including consumers who eat rice balls, has been growing as to whether or not the machine can produce “fluffy rice balls with a handmade feel”. is there. Therefore, in consideration of the above-mentioned problems, the present applicant re-analyzes the movement of a person holding a rice ball by hand, and in particular, after placing a predetermined ingredient on the cooked rice, As for the movement when folding the rice so as to wrap it and the movement of the mold when forming the rice ball after shaping the rice into a predetermined shape, it is as fluffy as handmade by bringing it as close to the movement of the human hand as possible. I came to the conclusion that I could make a rice ball.

この発明の目的は，上記の課題を解決することであり，コンビニエンスストアーやスーパマーケット等の店で販売されている梅干し，鮭，昆布，鰹節等の具入りおにぎりを製造する装置であって，３〜４個分の量の米飯を全体的に均一に解されたシート状米飯に成形し，解された具入りシート状米飯を成形装置によって所定の形状のおにぎりを形作るように，成形装置における折り込みコンベヤを独立して走行し且つシート状米飯を搬送するボトムベルトとシート状米飯の両側を折り込むサイドベルトによって構成し，あたかも人が手で握ったように米飯が押し硬めたり押し潰れておらず，ふっくらとした食感の良いおにぎりを成形装置によって成形すると共に，おにぎりの形状を変更する場合には，成形装置の成形円盤を単に交換するのみで，おにぎりを好ましい形状に成形し，しかもおにぎりを安定して高効率に製造して大量生産を可能にし，おにぎり製造のコストダウンを図ることができるおにぎり製造装置を提供することである。 An object of the present invention is to solve the above-mentioned problems, and is an apparatus for producing rice balls containing ingredients such as umeboshi, salmon, kelp, and bonito sold at stores such as convenience stores and supermarkets.

以下，図面を参照して，この発明によるおにぎり製造装置の実施例を説明する。このおにぎり製造装置の実施例では，概して，図１に示す米飯を搬送するのにベルトコンベヤ即ちコンベヤを使用したコンベヤ式おにぎり製造装置について説明している。この発明によるおにぎり製造装置は，複数のベルトを用いる折り込みコンベヤ３０を持つ成形装置３５であり，おにぎりの形状を変更する場合には，成形円盤３１を変更するのみであり，それ故に，おにぎりの成形型の交換が従来のものに比較してシンプルになり，また，おにぎりの多品種少量生産を要求されるおにぎり製造工場にとっては, 作業面のスペース上の問題, 費用面で大幅なコストダウンが可能になり，大きなメリットを発揮するものである。 Embodiments of a rice ball manufacturing apparatus according to the present invention will be described below with reference to the drawings. In this embodiment of the rice ball manufacturing apparatus, a conveyor type rice ball manufacturing apparatus using a belt conveyor, that is, a conveyor, for conveying the cooked rice shown in FIG. 1 is generally described. The rice ball manufacturing apparatus according to the present invention is a forming device 35 having a folding conveyor 30 that uses a plurality of belts. When the shape of the rice balls is changed, only the forming disk 31 is changed, and therefore the rice balls are formed. Mold change is simpler than conventional ones, and for rice ball manufacturing factories that require the production of small and high-quality rice balls, it is possible to significantly reduce costs in terms of work space and costs. This is a great advantage.

このおにぎり製造装置は，概して，架台３６に設置されたシート状米飯製造装置３３，架台７１に設置された具供給コンベヤ２９を備えたトッピングステーション３４，及び架台３７に設置された成形装置３５の３つの装置から構成されている。このおにぎり製造装置は，特に，図３に示すシート状米飯製造装置３３，及び図６〜８に示す成形装置３５に特徴を有している。図２及び図３に示すように，シート状米飯製造装置３３において，米飯リフター１２で揚げられた米飯供給部２３に供給された米飯５７は，米飯搬送コンベヤ１で搬送される途中で，先端に配置されている解し羽根７０である程度解されてホッパ２を通って米飯振り分け部２４に送られる。米飯振り分け部２４は，図４に示すように，フロントプレート３９，バックプレート６２，及び一対のサイドプレート３８に囲まれたスペースＳ１に，米飯５７をガイドするシュート３，切換えダンパ４０及び振り分けローラ４が設置されている。米飯振り分け部２４に送られた米飯５７は，図４に示すシュート３にガイドされて振り分けローラ４と切換えダンパ４０によって主米飯供給部２５と補填米飯供給部２６にそれぞれ振り分けられて供給される。 This rice ball manufacturing apparatus generally includes a sheet-like cooked rice manufacturing apparatus 33 installed on a gantry 36, a topping station 34 equipped with a tool supply conveyor 29 installed on a gantry 71, and a molding apparatus 35 installed on a gantry 37. It consists of two devices. This rice ball manufacturing apparatus is particularly characterized by a sheet-shaped cooked rice manufacturing apparatus 33 shown in FIG. 3 and a forming apparatus 35 shown in FIGS. As shown in FIG. 2 and FIG. 3, in the sheet-shaped cooked rice production apparatus 33, the cooked rice 57 supplied to the cooked rice supply unit 23 fried by the cooked rice lifter 12 is being transported by the cooked rice conveyor 1 at the tip. It is unraveled to some extent by the disassembling blades 70 arranged and sent to the cooked rice distribution unit 24 through the hopper 2. As shown in FIG. 4, the cooked rice sorting unit 24 includes a chute 3, a switching damper 40, and a sorting roller 4 for guiding the cooked rice 57 in a space S1 surrounded by the front plate 39, the back plate 62, and the pair of side plates 38. Is installed. The cooked rice 57 sent to the cooked rice sorting unit 24 is guided by the chute 3 shown in FIG. 4 and is sorted and supplied to the main cooked rice supply unit 25 and the supplemented cooked rice supply unit 26 by the sorting roller 4 and the switching damper 40.

主米飯供給部２５は，バックプレート４２，フロントプレート６３，一対のサイドプレート４３，４４で囲まれるスペースＳ２の下部にホッパ４１が配設されると共に，解しローラ４５と解しローラ４５に対向して送りローラ４６が設置されている。主米飯供給部２５のスペースＳ２には，所定の位置にレベルセンサ５８（第１レベルセンサ）が設置され，レベルセンサ５８は，主米飯供給部２５に供給される米飯５７の供給量を制限する機能を有している。また，補填米飯供給部２６は，バックプレート６５，フロントプレート６４，一対のサイドプレート６６，６７で囲まれるスペースＳ３の下部にホッパ６９が配設されると共に，主米飯供給部２５と同様の解しローラ４５と解しローラ４５に対向して送りローラ４６が設置されている。補填米飯供給部２６のスペースＳ３には，所定の位置にレベルセンサ６０（第３レベルセンサ）が設置され，レベルセンサ６０は，補填米飯供給部２６に供給される米飯５７の供給量を制限する機能を有している。 The main cooked rice supply unit 25 has a hopper 41 disposed below a space S2 surrounded by a back plate 42, a front plate 63, and a pair of side plates 43, 44, and is opposed to the unrolling roller 45 and the unrolling roller 45. Thus, a feed roller 46 is installed. In the space S2 of the main cooked rice supply unit 25, a level sensor 58 (first level sensor) is installed at a predetermined position, and the level sensor 58 limits the supply amount of the cooked rice 57 supplied to the main cooked rice supply unit 25. It has a function. The supplemented cooked rice supply unit 26 has a hopper 69 disposed below the space S3 surrounded by the back plate 65, the front plate 64, and the pair of side plates 66 and 67, and has the same solution as the main cooked rice supply unit 25. A feed roller 46 is disposed opposite the tear roller 45 and the tear roller 45. In the space S3 of the supplemented cooked rice supply unit 26, a level sensor 60 (third level sensor) is installed at a predetermined position. The level sensor 60 limits the amount of cooked rice 57 supplied to the supplemented cooked rice supply unit 26. It has a function.

主米飯供給部２５と補填米飯供給部２６との各々の米飯５７が，主米飯供給部２５と補填米飯供給部２６とに所定量，例えば，おにぎり３〜４個分の量の米飯が溜まり且つ条件が整うと運転が開始される。また，主米飯供給部２５と補填米飯供給部２６では，各々の送り出し機構の入口部に解し機構５，８を直結したことによって，米飯５７の解しが良好に行われる。主米飯供給部２５に振り分けられた米飯は，図３及び図４に示すように，解し機構５の送りローラ４６と解しローラ４５により全体が均一に解されながら，図５に示すシート状米飯送り出し機構６に送られる。また，補填米飯供給部２６に振り分けられた米飯は，同様に，図４に示す解し機構４の送りローラ４６と解しローラ４５により全体が均一に解されながら図３に示す補填米飯送り出し機構９に供給される。解し機構５としては，例えば，本出願人が開発した特許第４９４３６７９号に開示されているものを利用することができる。米飯５７が解し機構５，８を通過した直後の米飯５７は，解しローラ４５で全体が均一に良好に解されているため，送りローラ４６を通過する際には米飯５７の密度が一定になっている。それ故に，カッタ７，１０で米飯５７が切断された際に，シート状米飯５１の重量が極めて安定して均等なシート状米飯５１になる。シート状米飯５１の計量後に，補填量の指示が可能になり，シート状米飯５１の重量が安定し，例えば，１枚のシート状米飯５１が予め９５ｇｒと設定し，重量の許容範囲を±３ｇｒとすると，補填するべきシート状の補填米飯５４の必要量は極めて少なくなり，シート状補填米飯５４をシート状米飯５１に補填する機会が少なくなり，米飯５７の補填が簡素化することができる。 Each of the cooked rice 57 of the main cooked rice supply unit 25 and the supplemented cooked rice supply unit 26 accumulates a predetermined amount of cooked rice in the main cooked rice feed unit 25 and the supplemented cooked rice feed unit 26, for example, three to four rice balls. Operation starts when the conditions are met. Further, in the main cooked rice supply unit 25 and the supplemented cooked rice supply unit 26, the cooked rice 57 is unraveled satisfactorily by disassembling the mechanisms 5 and 8 directly at the inlet portions of the feeding mechanisms. As shown in FIGS. 3 and 4, the cooked rice distributed to the main cooked rice supply unit 25 is uniformly unwound by the feed roller 46 and the unwinding roller 45 of the unwinding mechanism 5, and the sheet shape illustrated in FIG. It is sent to the cooked rice delivery mechanism 6. Moreover, cooked rice, which is distributed to compensate the rice supply unit 26, likewise, compensation rice feeding mechanism shown in FIG. 3, while the whole is uniformly understood by loosening roller 45 construed feed roller 46 of the mechanism 4 shown in FIG. 4 9 is supplied. As the unraveling mechanism 5, for example, the one disclosed in Japanese Patent No. 4934679 developed by the present applicant can be used. The cooked rice 57 immediately after passing through the unwinding mechanism 5, 8 is unwound uniformly and satisfactorily by the unrolling roller 45, so the density of the cooked rice 57 is constant when passing through the feed roller 46. It has become. Therefore, when the cooked rice 57 is cut by the cutters 7 and 10, the weight of the sheet-like cooked rice 51 becomes very stable and becomes a uniform sheet-like cooked rice 51. After weighing the sheet-like cooked rice 51, it becomes possible to indicate the amount of filling, and the weight of the sheet-like cooked rice 51 is stabilized. For example, one sheet-like cooked rice 51 is set to 95 gr in advance, and the allowable range of weight is ± 3 gr. Then, the required amount of the sheet-like supplemented cooked rice 54 to be supplemented is extremely small, the opportunity for supplementing the sheet-like supplemented cooked rice 54 with the sheet-like cooked rice 51 is reduced, and the supplementation of the cooked rice 57 can be simplified.

図５に示すシート状米飯送り出し機構６（第１シート状米飯送り出し機構）に供給された米飯は，前段に配設された一対の送りローラ４９とその下方の後段に配設された一対の送りローラ５０とによって，シート状米飯５１になって送り出される。シート状米飯送り出し機構６は，解された米飯５７を所定の厚さのシート状米飯５１に形成するため，対向した一対の送りローラ４９，５０が少なくとも２段配設されており，送りローラ４９，５０間の間隔は前段送りローラ４９が後段送りローラ５０より大きく設定されており，送りローラ４９，５０間を通過する解された米飯５７が順次薄く所定の厚さのシート状米飯５１に成形される。補填米飯送り出し機構９は，シート状米飯送り出し機構６と同様に構成されている。シート状米飯送り出し機構６では，一対の下段の送りローラ５０の間隔は，一対の上段の送りローラ４９の間隔より狭くなるように設定されており，シート状米飯５１の厚みが徐々に薄くなるように構成されている。シート状米飯送り出し機構６は，バックプレート４７，一対のサイドプレート４８，４８，及びフロントプレート６８で囲まれるスペースＳ４に主米飯供給部２５からの解された米飯５７が供給される。スペースＳ４の下部には，対向して逆回転する一対の送りローラ４９，５０が複数段，図では２段設けられており，下段の送りローラ５０の下方にカッタ７が設置されている。解された米飯５７は，送りローラ４９，５０間と通過することによってシート状米飯５１に形成される。シート状米飯５１の厚みは，一対の送りローラ４９，５０の間隔をそれぞれ調節することによって予め決められた所定の厚みに調節することができる。また，シート状米飯５１の送り量は，送りローラ４９，５０の回転数を制御することによって調節され，予め決められた量のシート状米飯５１が送り出されるとカッタ７が作動して所定量のシート状米飯５１が計量コンベヤ２７に載置される。ここでは，図示していないが，シート状米飯送り出し機構６は，主米飯をシート状米飯５１に形成するものであるが，補填米飯５４も同様にシート状米飯送り出し機構を用いてシート状米飯５１に補填するシート状の補填米飯を形成することができる。 The cooked rice supplied to the sheet-like cooked rice feed mechanism 6 (first sheet-like cooked rice feed mechanism) shown in FIG. 5 is a pair of feed rollers 49 arranged in the preceding stage and a pair of feeds arranged in the lower stage below it. A sheet of cooked rice 51 is sent out by the roller 50. The sheet-shaped cooked rice feed mechanism 6 has at least two pairs of feed rollers 49 and 50 opposed to each other in order to form the uncooked cooked rice 57 into the sheet-shaped cooked rice 51 having a predetermined thickness. , 50 is set so that the front-stage feed roller 49 is larger than the rear-stage feed roller 50, and the cracked cooked rice 57 passing between the feed rollers 49, 50 is successively formed into a sheet-like cooked rice 51 having a predetermined thickness. Is done. The supplemented cooked rice feed mechanism 9 is configured in the same manner as the sheet-shaped cooked rice feed mechanism 6. In the sheet-like cooked rice feed mechanism 6, the interval between the pair of lower feed rollers 50 is set to be narrower than the interval between the pair of upper feed rollers 49, so that the thickness of the sheet-like cooked rice 51 gradually decreases. It is configured. Mechanism 6 feeding sheet rice, the backplate 47, rice 57 solutions have been from the main rice supply unit 25 to the space S4, surrounded by a pair of side plates 48,4 8 and the front plate 68, is supplied. At the bottom of the space S 4, a pair of feed rollers 49 and 50 a plurality of stages of reverse rotation opposite is provided two-stage in the figure, the cutter 7 below the lower feed row La 5 0 is established Yes. The uncooked cooked rice 57 is formed into the sheet-like cooked rice 51 by passing between the feed rollers 49 and 50. The thickness of the sheet-like cooked rice 51 can be adjusted to a predetermined thickness by adjusting the distance between the pair of feed rollers 49 and 50, respectively. Further, the feed amount of the sheet-like cooked rice 51 is adjusted by controlling the rotation speed of the feed rollers 49, 50. When a predetermined amount of the sheet-like cooked rice 51 is fed out, the cutter 7 is operated and a predetermined amount is fed. Sheet-shaped cooked rice 51 is placed on the weighing conveyor 27. Here, although not shown, the sheet-shaped cooked rice delivery mechanism 6 forms the main cooked rice into the sheet-shaped cooked rice 51, but the supplemented cooked rice 54 is similarly formed using the sheet-shaped cooked rice feed mechanism 51. It is possible to form a supplementary cooked rice in a sheet form to be supplemented.

シート状米飯送り出し機構６から所定量のシート状米飯５１が送り出されると，一対の送りローラ５０の下方に配置されているカッタ７が作動して，シート状米飯５１が切断され，切断されたシート状米飯５１が計量コンベヤ２７上に落下する。計量コンベヤ２７上に落下したシート状米飯５１は搬送されながら計量される。シート状米飯５１は，計量コンベヤ２７から間欠作動コンベヤ２８に移動し，間欠作動コンベヤ２８の上方には，補填米飯供給部２６が配設されており，シート状米飯５１が予め決められた所定量より不足している場合には，補填米飯供給部２６に指令が発され，不足分の量の米飯が補填米飯供給部２６の下方に設置されたシャッタ状のカッタ１０が作動し，所定量の補填米飯５４は，間欠作動コンベヤ２８上のシート状米飯５１が補填米飯供給部２６を通過する時に，シート状米飯５１上に載せられて補填される。この時，予め決められた所定量に対して許容範囲の重量のシート状米飯５１，或いはオーバしたシート状米飯５１は，補填米飯供給部２６を通過するように設定されている。補填米飯５４は，主米飯供給部２５の解し機構５とシート状米飯送り出し機構６と同様の機構に構成された解し機構８とシート状の補填米飯送り出し機構９を使用して，指令によりカッタ１０が作動して補填米飯供給部２６の米飯から不足分が切り落とされ，シート状米飯５１上に載せられる。また，間欠作動コンベア２８には，シート状米飯５１の姿勢即ち向きを整列させるシート状米飯整列機構１１が設けられている。シート状米飯５１は，シート状米飯整列機構１１によって折り込みコンベヤ３０のボトムベルト１３と一対のサイドベルト１４に対して直角に進入するように姿勢が調整されて，それによって，シート状米飯５１の両側がサイドベルト１３によってそれぞれ折り込まれて，具５２がシート状米飯５１に包み込まれるようになる。 When a predetermined amount of sheet-like cooked rice 51 is fed from the sheet-like cooked rice feed mechanism 6, the cutter 7 disposed below the pair of feed rollers 50 is operated to cut the sheet-like cooked rice 51, and the cut sheet The cooked rice 51 falls on the weighing conveyor 27. The sheet-like cooked rice 51 dropped on the weighing conveyor 27 is weighed while being conveyed. The sheet-like cooked rice 51 moves from the weighing conveyor 27 to the intermittently-operated conveyor 28, and the supplementary cooked-rice supply unit 26 is disposed above the intermittently-operated conveyor 28 so that the sheet-like cooked rice 51 has a predetermined amount. If there is a further shortage, a command is issued to the supplemented rice supply unit 26, and the shutter-like cutter 10 installed below the supplemented rice supply unit 26 operates to supply a predetermined amount of rice. The supplementary cooked rice 54 is placed and supplemented on the sheet-like cooked rice 51 when the sheet-like cooked rice 51 on the intermittent operation conveyor 28 passes through the supplemented cooked rice supply unit 26. At this time, the sheet-shaped cooked rice 51 having a weight within an allowable range with respect to a predetermined amount set in advance or the sheet-shaped cooked rice 51 that has exceeded is set to pass through the supplemented cooked rice supply unit 26. The supplementary cooked rice 54 is used in accordance with a command by using the unraveling mechanism 8 and the sheet-shaped supplemented rice feeding mechanism 9 configured in the same manner as the unraveling mechanism 5 and the sheet-shaped cooked rice feeding mechanism 6 of the main cooked rice supply unit 25. The cutter 10 is actuated so that the shortage is cut off from the cooked rice in the supplemented cooked rice supply unit 26 and placed on the cooked rice 51. Further, the intermittently operated conveyor 28 is provided with a sheet-like cooked rice alignment mechanism 11 that aligns the posture, that is, the orientation of the sheet-like cooked rice 51. The posture of the sheet-like cooked rice 51 is adjusted by the sheet-like cooked rice aligning mechanism 11 so as to enter at right angles to the bottom belt 13 and the pair of side belts 14 of the folding conveyor 30, thereby both sides of the sheet-like cooked rice 51. Are folded by the side belts 13 so that the tool 52 is wrapped in the sheet-like cooked rice 51.

このおにぎり製造装置では，上記のように，主米飯供給部２５では，解し機構５の上方にレベルセンサ５８が設けられ，解し機構５とシート状米飯送り出し機構６との間にレベルセンサ５９が設けられている。補填米飯供給部２６では，解し機構８の上方にレベルセンサ６０が設けられ，解し機構８と補填米飯送り出し機構９との間にレベルセンサ６１が設けられている。レベルセンサ５８が米飯５７を感知して作動すると，米飯振り分け部２４及び米飯搬送コンベヤ１が停止して米飯５７の送り込みを停止する。また，レベルセンサ５９が解された米飯５７を感知して作動すると，解し機構５の解しローラ４５と送りローラ４６が停止する。それ故に，レベルセンサ５８〜６１の機能により，米飯５７が余分に送り込まれて米飯５７が溜まった状態にならず，米飯５７の自重で米飯５７が押し付けられて塊になることがないので，常にうんわりした均一の米飯５７の状態を維持できる。また，予め決められた所定量に調整されたシート状米飯５１は，間欠作動コンベヤ２８上に設けられたシート状米飯整列機構１１を通過して，シート状米飯５１の姿勢即ち向きが一方向に整えられ，トッピングステーション３４の具供給コンベヤ２９に送り込まれる。具供給コンベヤ２９では，図１に示すように，人Ｈの手作業により，梅干し，鮭，昆布，タラコ等の各種の具５２がシート状米飯５１上に載せられる。具５２が載せられたシート状米飯５１は，成形装置３５に送り込まれる。 In this rice ball manufacturing apparatus, as described above, in the main cooked rice supply unit 25, the level sensor 58 is provided above the unraveling mechanism 5, and the level sensor 59 is provided between the unraveling mechanism 5 and the sheet-like cooked rice feed mechanism 6. Is provided. In the supplemented cooked rice supply unit 26, a level sensor 60 is provided above the unlocking mechanism 8, and a level sensor 61 is provided between the unlocking mechanism 8 and the supplemented cooked rice delivery mechanism 9. When the level sensor 58 senses and operates the cooked rice 57, the cooked rice sorting unit 24 and the cooked rice conveyor 1 stop, and the feeding of the cooked rice 57 is stopped. Further, when the level sensor 59 senses and operates the cracked cooked rice 57, the unrolling roller 45 and the feed roller 46 of the unwinding mechanism 5 are stopped. Therefore, by the function of the level sensors 58 to 61, the cooked rice 57 is not fed in excessively, and the cooked rice 57 does not accumulate, and the cooked rice 57 is not pushed into the lump by its own weight. The state of the smooth and uniform cooked rice 57 can be maintained. The sheet-shaped cooked rice 51 adjusted to a predetermined amount passes through the sheet-shaped cooked rice alignment mechanism 11 provided on the intermittent operation conveyor 28, and the sheet-shaped cooked rice 51 is oriented in one direction. It is prepared and fed to the component supply conveyor 29 of the topping station 34. As shown in FIG. 1, in the tool supply conveyor 29, various tools 52 such as pickled plums, rice cakes, kelp, taraco, etc. are placed on the sheet-like cooked rice 51 by the manual work of the person H. The sheet-like cooked rice 51 on which the tool 52 is placed is fed into the molding device 35.

このおにぎり製造装置において，成形装置３５は，主として，図６及び図７に示すように，シート状米飯５１の折り込みコンベヤ３０とその後流の成形円盤３１から構成されている。このおにぎり製造装置は，特に，成形装置３５における折り込みコンベヤ３０に特徴を有している。折り込みコンベヤ３０は，図９〜図１０に示すように，具５２が中央部に載置されたシート状米飯５１の中央部を載置して移動するボトムベルト１３，及びボトムベルト１３の両側に近接して配設され且つボトムベルト１３に同期して移動するシート状米飯５１の両側側部をそれぞれ載置して移動する一対のサイドベルト１４から構成されている。ボトムベルト１３は，水平状態に配設されてシート状米飯５１を搬送する。また，サイドベルト１４は，折り込みコンベヤ３０の始端ではボトムベルト１３と同様に水平状態になっており，サイドベルト１４の進行に従って立ち上がり，折り込みコンベヤ３０の終端ではボトムベルト１３に対して垂直状態になって進行する。従って，成形装置３５において，折り込みコンベヤ３０では，ボトムベルト１３の両側に同期して移動するサイドベルト１４でシート状米飯５１を折り込む際に，サイドベルト１４が，特に図８に示すように，斜めに上がるように進行しながらシート状米飯５１を折り込むので，シート状米飯５１に無理な力がかからず，シート状米飯５１が無理なく的確に形崩れしないように折り込むことができることである。 In this rice ball manufacturing apparatus, as shown in FIGS. 6 and 7, the forming apparatus 35 is mainly composed of a folding conveyor 30 for the sheet-like cooked rice 51 and a forming disk 31 in the subsequent flow. This rice ball manufacturing apparatus is particularly characterized by the folding conveyor 30 in the molding apparatus 35. As shown in FIGS. 9 to 10, the folding conveyor 30 is placed on the bottom belt 13 on which the center portion of the sheet-like cooked rice 51 on which the tool 52 is placed is moved, and on both sides of the bottom belt 13. It is composed of a pair of side belts 14 which are placed close to each other and move on the both sides of the sheet-like cooked rice 51 which moves in synchronization with the bottom belt 13. The bottom belt 13 is disposed in a horizontal state and conveys the sheet-like cooked rice 51. Further, the side belt 14 is in a horizontal state at the starting end of the folding conveyor 30 in the same manner as the bottom belt 13, rises as the side belt 14 advances, and becomes vertical with respect to the bottom belt 13 at the end of the folding conveyor 30. And proceed. Therefore, in the forming apparatus 35, when the sheet-shaped cooked rice 51 is folded by the side belt 14 that moves in synchronization with both sides of the bottom belt 13 in the folding conveyor 30, the side belt 14 is inclined as shown in FIG. The sheet-like cooked rice 51 is folded while proceeding so that the sheet-like cooked rice 51 is not subjected to excessive force, and the sheet-like cooked rice 51 can be folded so as not to be deformed without difficulty.

折り込みコンベヤ３０は，図９又は図１０に示すように，ボトムベルト１３は常に水平状態で進み，サイドベルト１４は水平状態から徐々に立ち上がって垂直状態に成るように作動され，それに従って折り込みコンベヤ３０で搬送されるシート状米飯５１の両側がサイドベルト１４によって折り曲げられ，シート状米飯５１上の具５２がシート状米飯５１の両側で包み込むようになる。シート状米飯５１の折り込み順序は，図９の（Ａ），（Ｂ），（Ｃ）に示すように，最初は水平状態で進行するサイドベルト１４上のシート状米飯５１は，ボトムベルト１３の両側のサイドベルト１４が若干斜めに上昇しつつ傾きを変えてシート状米飯５１の両側で具５２を包み込むように垂直状態に折り込まれ，サイドベルト１４の終端では成形ロール１５が設置されているので，図１０の（Ｄ）及び（Ｅ）に示すように，ボトムベルト１３及びその両側の固定サイドガイド２１が架台３７に設けられており，ボトムベルト１３で搬送される具５２が載置されたシート状米飯５１の両側の合せ部の両側の合せ部が成形ロール１５によって整えられ，更に成形ロール１５の後流に設置された成形ロール１６によって，図１０の（Ｅ）に示すように，シート状米飯５１の中心部に具５２が包み込まれて略円筒状に成形される。折り込みコンベヤ３０では，シート状米飯５１は，ボトムベルト１３によって搬送されることになる。 As shown in FIG. 9 or FIG. 10, the folding conveyor 30 is operated so that the bottom belt 13 always advances in a horizontal state and the side belt 14 gradually rises from the horizontal state to become a vertical state, and accordingly the folding conveyor 30 The both sides of the sheet-like cooked rice 51 conveyed by the above are bent by the side belt 14, and the tool 52 on the sheet-like cooked rice 51 is wrapped around the both sides of the sheet-like cooked rice 51. As shown in FIGS. 9A, 9B, and 9C, the sheet-shaped cooked rice 51 on the side belt 14 that first proceeds in a horizontal state is formed on the bottom belt 13 as shown in FIGS. Since the side belts 14 on both sides are slightly tilted up and changed in inclination to be wrapped in a vertical state so as to wrap the tool 52 on both sides of the sheet-like cooked rice 51, the forming roll 15 is installed at the end of the side belt 14. , as shown in (D) and (E) in FIG. 10, a bottom belt 13 and on both sides of the fixed side guide 21 that is provided on the frame 37, immediately 52 carried by the bottom belt 13 is placed both sides of the mating portion of the mating portions on both sides of the sheet-like cooked rice 51 is trimmed by the forming rolls 15, further by forming roll 16 installed on the downstream of the forming roll 15, shown in (E) of FIG. 10 , The ingredients 52 in the center of the sheet-like cooked rice 51 is wrapped is formed in a substantially cylindrical shape.
